Abstract: Category: Basic Sciences/Biologics; Sports; Trauma Introduction/Purpose: Mesenchymal stem cells (MSCs) have demonstrated promise in augmenting the surgical repair of full thickness tendon tears. Despite this promise, obtaining a therapeutic concentration of MSCs is time-, labor- and resource intensive, and is subject to ever-tightening governmental regulations. Our group recently demonstrated that postoperative mobilization of MSCs from the marrow compartment and into peripheral blood via subcutaneous granulocyte- colony stimulating factor administration enhanced tendon-bone healing in a rat model of surgical repair of a full-thickness supraspinatus tendon tear. We hypothesized that combining postoperative stem cell mobilization with local delivery of a chemokine that stimulates MSC chemotaxis would enhance the surgical repair of a mid-substance Achilles tendon transection. Methods: Following IACUC approval, Achilles tendons were unilaterally frayed via multiple longitudinal scalpel blade nicks in 24 Lewis rats. Tendons were then surgically transected, followed by repair with braided non-absorbable suture in a modified-Kessler pattern. Based on randomization (n=6/group), the tendon anastomosis was coated with a resorbable chitosan hydrogel containing 100 ng of the chemokine, CCL5 (RANTES), or hydrogel without RANTES. Skin closure and anesthesia recovery were then performed; rats were allowed ad libitum activity. Beginning 24 hours postoperatively, rats received a daily subcutaneous injection of either a peripheral blood mobilizing agent, AMD3100 (5 mg/kg), or saline; dosing was repeated at 48 and 72 hours. At the 4- week endpoint, Achilles tendons harvested en bloc. Decalcified histologic sections were stained with H&E and Alcian Blue as well as immunostained for Collagen III, CD163, and CD68. Slides were digitized (40x magnification) and graded by blinded reviewers via modified-Bonar score to assess tendon integrity. Results: Rats that received local application of RANTES-loaded chitosan hydrogel had worse (higher) modified-Bonar subscores with respect to tenocyte morphology, collagen orientation, and ground substance staining, though none of these comparisons were statistically significant (p=0.068, p=0.672, and p=0.407, respectively). Animals that received subcutaneous AMD3100 alone, or in conjunction with RANTES-loaded chitosan hydrogel displayed the best (lowest) total modified Bonar scores, though these comparisons were also not statistically significant (p = 0.498). No significant differences were found with respect to CD163 (p=0.132) and CD68 (p=0.104) staining. Despite a lack of statistical significance, animals that received AMD3100 displayed a higher number of both macrophage subtypes. No differences were found with respect to Collagen III immunostaining (p=0.808). Conclusion: Tendon repair and regeneration remains a significant clinical challenge, which may be aided by MSC transplantation. The mobilization of endogenous marrow-derived MSCs into peripheral blood and subsequent recruitment via local chemokine delivery may be an efficacious way to enhance tendon repair without the need for ex vivo processing. We failed to demonstrate significant effects of stem cell mobilization via AMD3100 injections, and chemokine-directed recruitment, though trends were present indicating that AMD3100 alone may be beneficial. Additional work is required to draw any translatable conclusions from this research.

Abstract: Category: Midfoot/Forefoot Introduction/Purpose: An adult flatfoot deformity is a complex pathology that has been attempted to be addressed surgically with a variety of different procedures. Transfer of the flexor tendon has been a cornerstone of the treatment of flatfoot deformity for years. After the procedure, the appearance of the bony correction of the foot is noticeable on radiography, but after surgery when the patient begins to bear the weight the soft tissue laxity affects the achieved bony correction when compared to non- weight bearing images. This study aims to identify the effects of tendon transfer on bony and soft tissue after weight-bearing to better predict what the outcomes of surgery will be. Methods: 29 patients were included. there were 18 patients that underwent tendon transfer as part of their flat foot correction and 11 patients that underwent non-tendon transfer procedure for correction of flat foot deformity. Imaging was performed on patient's weight bearing (WB) and non-weight bearing (NWB) before and after surgery. X-ray measurements included Angles: calcaneal pitch (ML-CP), talo-1st metatarsal (ML-T1MT),talocalcaneal (ML-TC), talar declination (ML-Tdec), calcaneal 1st metatarsal (ML-C1MT) and Distances: talar height (ML-Tal-h), navicular height (ML-Nav-h), 1st cuneiform height (ML-1CN-h), cuboid height (ML-Cub-h), and 1st to 5th metatarsal distance (ML-1CN/5MT) in lateral X-ray and Angles: talonavicular coverage (AP-TN), talar 1st metatarsal (AP-T1MT), talar 2nd metatarsal (AP-T2MT) and Distances: talonavicular uncoverage distance in AP. The differences in measurement between the pre op post op non weight bearing considered as bony correction effect The differences in measurement between the pre op post op weight bearing considered as soft tissue effect. Results: the results from non-weight bearing imaging, tendon transfer had a statistically significant impact on calcaneal pitch (, p=0.026), Talo-1st metatarsal (p=0.048), talar declination ( p=0.038), talar height (p=0.016), navicular height ( p=0.014), 1st cuneiform height (p=0.001), talonavicular coverage (p=0.019), talar-1st metatarsal angle (p=0.015), and talar to 2nd metatarsal angle ( p=0.001). the results from WBimaging, tendon transfer had a statistically significant impact on calcaneal pitch ( p=0.000), calcaneal 1st metatarsal (p=0.02), talar height (35 to 39, p=0.003), navicular height ( p=0.002), 1st cuneiform height (p=0.016), cuboid height ( p=0.016), 1st to 5th The post-op effect calcaneal pitch was 12 degrees of difference in NWB compared to 6 degrees of difference in WB The effect on talar height, navicular height, and 1st cuneiform height was 10mm, 9mm, and 8mm, respectively, in NWBimages. This compares to an effect of 4mm, 6mm, and 4mm, respectively, WB imaging. Conclusion: When comparing NWB to WBimages, the effect of surgery on flat foot correction is consistently less pronounced inWB. there will be a difference between the bony correction and soft tissue correction. there is still a significant soft tissue effect seen in WBimaging. The comparison between NWB, WB changes shows that the soft tissue effect is around 50% of the bony correction on several key measurements. These include calcaneal pitch and talar, navicular, and 1st cuneiform height. These results provide a framework for establishing the soft tissue effect that tendon transfer surgery provides for flat foot correction surgery.

Abstract: Category: Ankle; Sports Introduction/Purpose: studies demonstrated that mechanical axis alignment affects the clinical outcome of the chondral repair surgery in the knee. Reduction in stress concentration around chondral defects with HTO has been found to favor cartilage repair in knee surgery. this study aimed to determine the relationship between the tibia mechanical axis alignment and OLT size and location. Methods: 57 patients that underwent OLT repair between 2016-2020 were included. X-rays and MRIs of the ankle were used to collect data on OLT in the study group. X-ray measurements included (a)-measured as distance from where vertical line through center of tibia crosses to center the talar joint in AP view (medial, lateral), (b)- measured as distance from where vertical line through center of tibia crosses to the center talar body in lateral view (ant, post). The coverage angle, TLS, TAS, MA, TI, TTI angles were measured. MRI measurements included distance of the edge of the OLT lesion from the center of the talar surface, in three plans, and for location of the OLT lesion based on the 9-zone grid system. Results: 37.3% of these patients had the mechanical axis of the joint cross posterolaterally, 15.6% anteromedially, 5.9% anterolaterally, and 3.9% posteromedially. 33.3% had the mechanical axis cross posteriorly along the midline of the lateral axis. Using the 9-zone grid to localize lesion location, lesions were most often seen in location 6 (37.3%), location 7 (21.6%), location 9 (21.6%), and location 4 (19.6%). Of note, 36.8% of patients with a posterolateral axis had lesions at location 6 and 26.3% at location 9. For patients with poster joint axis along the midline of the lateral axis, 47.1% had lesions at location 6 and 23.5% at location 7. There is a correlation between Lesion Surface Area and axis location in the AP view (Correlation coefficient: 0.301, P Value: 0.023). we found a significant difference for coverage angle (P

Abstract: Category: Other; Diabetes Introduction/Purpose: Infections pertaining to orthopaedic surgery play a major role in patient morbidity and increased healthcare-associated expenses. In the setting of foot and ankle surgery for infection, it is common practice to send acid-fast bacilli (AFB) and fungal intraoperative cultures, although there is no standard protocol in place. In this study, the rate of positive AFB and fungal cultures and associated costs in a consecutive series of foot and ankle surgeries was retrospectively assessed. Methods: Under an IRB-approved protocol, CPT codes were used to identify 447 procedures in 320 patients, who underwent foot and ankle surgery for infection by fellowship-trained foot and ankle orthopaedic surgeons at a Level 1, private, academic hospital from 2014 to 2019. A medical records review was performed to collect microbiology and patient demographic data. Materials and labor cost data, which was provided by the institution, was used to quantify a total culture cost. Results: In this series, there were 185 male and 135 female patients with an average age of 57 years (range, 10-105) and average BMI of 31 kg/m 2 (range, 13-56). No patients had positive AFB cultures and 20 patients (7.5%) had positive fungal cultures. There were 434 AFB and 525 fungal cultures performed during these procedures. Based on total cultures performed, there were 0% (0/434) AFB and 5% (26/525) fungal culture positivity rates. The total intra-institutional cost (i.e. labor and materials) for AFB cultures was $23,967. The total labor/materials cost for negative and positive fungal cultures was $12,428 and $2,371, respectively. The total labor/materials cost for all the cultures obtained over the time frame of our study was $38,767. Conclusion: This study highlighted low rates of positive AFB and fungal cultures in the orthopaedic foot and ankle surgery service in a 6-year retrospective review, as well as substantial institutional costs of routine use of intraoperative cultures. While this series included cases from three fellowship-trained foot and ankle orthopaedic surgeons, this study will be expanded to analyze AFB and fungal culturing practices and cost in other orthopaedic subspecialties. Creating and implementing a standardized protocol may achieve cost effectiveness of cultures without diminishing patient outcomes.

Subjects: Orthopedic surgery, RD701-811
Abstract: Category: Ankle; Hindfoot; Sports Introduction/Purpose: Surgical treatment of adult flatfoot deformity has traditionally be driven by tendon transfers and osteotomy. In acquired deformity, injury to the spring ligament and superficial deltoid ligament is common. The procedures mentioned previously do nothing to restore the function of the medial ligament complex. Studies have shown that reconstruction of the medial ligament complex, and thus the medial talonavicular joint, has benefit to patient outcomes. The question still remains of how much correction the medial ligament reconstruction confers on its own. The purpose of this study is to compare isolated medial ligament reconstruction procedures to other flat foot correcting procedures in the treatment of acquired flat foot deformity. Methods: 18 patients were identified that underwent procedure for flatfoot deformity. Of these patients there were 7 patients that underwent isolated medial ligament complex reconstruction and 11 patients that underwent non-tendon transfer procedure for correction of flat foot deformity. Imaging was performed on patient's weight bearing (WB) and non-weight bearing (NWB) before and after surgery. Measurements included Angles: calcaneal pitch, talo-1st metatarsal, talocalcaneal, talar declination, calcaneal 1st metatarsal and Distances: talar height, navicular height, 1st cuneiform height, cuboid height, and 1st to 5th metatarsal distance in lateral X-ray, and Angles: talonavicular coverage, talar 1st metatarsal, talar 2nd metatarsal and Distances: talonavicular uncoverage distance in AP. The differences in measurement between the pre-op and post-op non-weight bearing are considered as bony correction effect while differences between pre-op and post-op weight bearingare considered as soft tissue correction Results: For non-weight bearing; medial ligament reconstruction impact was seen on calcaneal pitch (19 to 35 degrees, p=0.007), 1st cuneiform height (21 to 28mm, p=0.016), talonavicular coverage (6 to 3 degrees, p=0.026), and Talar 1st metatarsal angle (14 to 7 degrees, p=0.008). Other corrections had an impact on calcaneal pitch (15 to 24 degrees, p=0.006), Talo-1st metatarsal angle (11 to 6 degrees, p=0.019), Calcaneal 1st metatarsal (139 to 129 degrees, p=0.044), Talar height (31 to 42mm, p=0.001), navicular height (24 to 34mm, p=0.002), and 1st cuneiform height (18 to 22mm, p=0.016). For weight bearing; reconstruction impact was seen on talocalcaneal angle (36 to 44 degrees, p=0.011), 1st-5thmetatarsal distance (12 to 18mm, p=0.047), and hindfoot moment arm (16 to 6mm, p=0.031). Other corrections had an impact on talar height (34 to 40mm, p=0.028), navicular height (26 to 30mm, p=0.031), cuboid height (p=0.021), and hindfoot alignment angle (17 to 7 degrees, p=0.003). Conclusion: When compared to procedures that only address bony changes in the foot, it is clear from this study that medial ligament repair plays a different, but significant, role in correction of flat foot deformity. Interestingly, the non-weight bearing and weight bearing results show that medial ligament reconstruction affects different aspects of the correction in these two distinct phases. This study serves to suggest that medial ligament reconstruction has a role in the correction of flat foot deformity that is not completely addressed in the more common procedures performed.

6. Applying the Periprosthetic Joint Infection Consensus Definition to a Case Series of Revision Foot and Ankle Implant-Associated and Infection-Suspected Procedures to Assess Diagnosis

Author: Erin A. Baker PhD, Jackson Harley BS, Corinn Gehrke MS, David J. Ciufo MD, Paul T. Fortin MD, and Zachary M. Vaupel MD
Subjects: Orthopedic surgery, RD701-811
Abstract: Category: Other Introduction/Purpose: Periprosthetic joint infection (PJI) affects 2-3% of all total joint replacement cases. In 10-30% of these cases, the organism is unidentifiable, which may impact treatment planning and outcomes. In this study, suspected periprosthetic infections of foot and ankle procedures treated by four foot and ankle-trained orthopaedic surgeons were retrospectively reviewed to determine culture status and applicability of the 2018 International Consensus Meeting on Orthopaedic Infections (ICM) Revision classification system. Methods: Under an IRB-approved protocol, cases of suspected infection, based on ICD-9/10 codes, from cases performed at a Level 1, private, academic hospital from October 2014 to November 2019 were reviewed for demographic, surgical, and infection-related data. Results: Of the 210 revision cases coded for infection, 82 met the inclusion criteria of the study; cases included removal of an implant and were not wound infection-related only. Preoperatively and intraoperatively, 10 (12%) and 59 (72%) cases were culture-positive, respectively. In this series, 21 (26%) cases met the ICM Revision major criteria and 36 (44%) cases met the threshold for ICM Revision minor criteria; overall, 43 (52%) cases were defined as infected by the 2018 ICM Revision classification system. Conclusion: This study reviewed and identified culture status and infection by the 2018 ICM classification system. In this series of 82 cases, approximately half of the cases met the criteria for infection diagnosis, according to the most recently revised ICM classification system, although nearly three-quarters of the population had at least one positively-identified intraoperative culture. Further data analysis is ongoing to assess the correlation between ICM scoring with pre/postoperative treatment and outcomes.

Abstract: Category: Hindfoot; Ankle; Ankle Arthritis; Basic Sciences/Biologics; Trauma Introduction/Purpose: Autologous bone graft is an important tool in the foot and ankle surgeon’s arsenal, and remains the gold standard despite the release of new biologics. The Reamer-Irrigator-Aspirator (RIA) system has become an option for local intramedullary bone graft harvest. Evidence supports the quality of graft and safety of RIA in the femur, and some series have demonstrated its value in tibial reaming for hindfoot fusion. However, there has been no analysis of the mechanical effects of the system on the tibia. The purpose of this study is to investigate the effect of retrograde intramedullary reaming on the mechanical properties of cadaveric tibias, with the hypothesis that this will produce no significant difference in torsional strength between groups. Methods: Intact, fresh frozen tibias were obtained for testing, totaling 11 matched pairs. One tibia was chosen for reaming from each pair with pre-test randomization. The selected tibia was reamed in a retrograde fashion over a guidewire to 12mm, which is the smallest diameter RIA device available. Each tibia was potted and mounted in a custom jig for testing on a servohydraulic test frame. Each specimen was first tested non-destructively for compressive properties using standardized loading rates. Each specimen was then loaded in torsion under constant angular velocity of 9˚/second until failure or the limit of the load cell was reached. Mechanical properties were determined from the load-displacement curve and compared between reamed and unreamed matched pairs using paired samples statistics, with statistical significance set at p=0.05. Results: Specimens were of mean age 56 (range 39-67) years, with 55% being female. The mean compressive stiffness of reamed (560.4 +- 111.7 N/mm) and unreamed (628.2 +- 117.2 N/mm) tibias were not statistically different (p = 0.167). Nine of the reamed specimens and 10 of the unreamed specimens fractured during torsional testing. Torsional testing for stiffness (178.4 Nm/rad +- 59.4 vs 168.1 +- 40.8, p=0.370), rigidity (50.4 Nm2/rad +- 19.1 vs 47.0 +- 13.7, p=0.331), and ultimate load capacity (71.2 Nm +- 24.3 vs 71.9 +- 20.5, p=0.880) showed minimal differences between reamed and unreamed specimens, respectively. Conclusion: Mechanical testing identified no statistically significant differences in torsional or compressive properties of our cadaveric tibias after intramedullary reaming. There was a trend towards decreased compressive stiffness, but this is not a common mechanism of fracture. Our findings suggest that the use of the smallest size RIA system in the tibia does not drastically alter the mechanical properties or require prophylactic fixation. The RIA can be used safely as a method of bone graft harvest or intramedullary debridement in the tibia, as long as appropriate technique is used to avoid eccentric reaming or excessive blood loss.

Author: Erin A. Baker PhD, Corinn Gehrke MS, David J. Ciufo MD, Zachary M. Vaupel MD, and Paul T. Fortin MD
Subjects: Orthopedic surgery, RD701-811
Abstract: Category: Other; Ankle; Ankle Arthritis; Arthroscopy; Diabetes; Hindfoot; Lesser Toes; Midfoot/Forefoot; Trauma Introduction/Purpose: Reduction of postoperative readmissions is an important goal for the improvement of patient outcomes and satisfaction, as well as mitigating rising healthcare costs. As a result of changing federal and insurer guidelines and requirements, hospitals monitor and report 90-day all-cause readmissions. This data can be used to drive both local and national improvements in patient care. The purpose of our study is to evaluate patient and perioperative factors associated with 90-day readmissions specifically in a foot and ankle surgery population. Methods: After obtaining Institutional Review Board approval, admissions and readmissions data from October 2012 to September 2016 at a Level 1, private, academic hospital were reviewed for patients treated surgically by four foot and ankle orthopaedic surgeons. Only foot and ankle surgical procedures were included, as identified by diagnosis codes (ICD-9/ICD-10), performed on patients from 10-95 years of age. All-cause readmission rate was recorded. A medical records review was performed to collect patient demographics, admissions, readmissions, and surgical data. Data was analyzed using an analysis of variance model with a Dunn’s post-hoc test as well as Spearman rank order correlation test, with significance set at α=0.05. Results: 6,054 patients were identified, and 4,578 met study inclusion criteria; 4,404 cases did not result in readmission and 174 cases resulted in readmission within 90 days of discharge of the index inpatient/outpatient case, leading to an overall, all-cause readmission rate of 3.80%. Between non-readmission and readmission cohorts, there were no significant differences in patient age (p=0.627) or sex (p=0.208; female: male ratio in both cohorts ˜ 60% v. 40%); however, there was a significant difference in BMI (29.8 v. 31.9, respectively; p

Abstract: There is limited literature on axial rotation of the ankle or variations in anatomy of the talus. We aim to evaluate the rotational profile of the distal tibia and its relationship to talus morphology, radiographic foot-type, and tibiotalar tilt in arthritic ankles.Preoperative imaging was reviewed in 173 consecutive patients with ankle arthritis. CT measurements were used to calculate tibial torsion and the talar neck-body angle (TNBA). Tibiotalar tilt and foot-type were measured on weightbearing plain radiographs.Measurements indicated mean external tibial torsion of 29.2±9.1˚ and TNBA of 35.2±7.5˚ medial. Tibiotalar tilt ranged from 48˚ varus to 23.5˚ valgus. A moderate association between increasing external tibial torsion and decreasing TNBA was found (ρ=-0.576, p.0001). Weak relationships were found between external tibial torsion and varus tibiotalar tilt (ρ=-0.239, p=.014) and plantarflexion of the talo-first metatarsal angle (ρ=-0.218, p.025).We observed a statistically significant correlation between tibial torsion and morphology of the talus, tibiotalar tilt, and first ray plantarflexion. This previously unreported association may provide information regarding the development of foot and ankle deformity and pathology.Level III.

Abstract: Osteochondral lesions of the talus (OLTs) are an increasingly implicated cause of ankle pain and instability. Several treatment methods exist with varying clinical outcomes. Due in part to successful osteochondral allografting (OCA) in other joints, such as the knee and shoulder, OCA has gained popularity as a treatment option, especially in the setting of large lesions. The clinical outcomes of talar OCA have been inconsistent relative to the positive results observed in other joints. Current literature regarding OCA failure focuses mainly on 3 factors: the effect of graft storage conditions on chondrocyte viability, graft/lesion size, and operative technique. Several preclinical studies have demonstrated the ability for bone and cartilage tissue to invoke an immune response, and a limited number of clinical studies have suggested that this response may have the potential to influence outcomes after transplantation. Further research is warranted to investigate the role of immunological mechanisms as an etiology of OCA failure.Level of Evidence: Level V, expert opinion.

Methods: Intact, fresh frozen tibias were obtained for testing, totaling 11 matched pairs. One tibia was chosen for reaming from each pair with pre-test randomization. The selected tibia was reamed in a retrograde fashion over a guidewire to 12mm, which is the smallest diameter RIA device available. Each tibia was potted and mounted in a custom jig for testing on a servohydraulic test frame. Each specimen was first tested non-destructively for compressive properties using standardized loading rates. Each specimen was then loaded in torsion under constant angular velocity of 9˚/second until failure or the limit of the load cell was reached. Mechanical properties were determined from the load-displacement curve and compared between reamed and unreamed matched pairs using paired samples statistics, with statistical significance set at p=0.05. Results: Specimens were of mean age 56 (range 39-67) years, with 55% being female. The mean compressive stiffness of reamed (560.4 +- 111.7 N/mm) and unreamed (628.2 +- 117.2 N/mm) tibias were not statistically different (p = 0.167). Nine of the reamed specimens and 10 of the unreamed specimens fractured during torsional testing. Torsional testing for stiffness (178.4 Nm/rad +- 59.4 vs 168.1 +- 40.8, p=0.370), rigidity (50.4 Nm2/rad +- 19.1 vs 47.0 +- 13.7, p=0.331), and ultimate load capacity (71.2 Nm +- 24.3 vs 71.9 +- 20.5, p=0.880) showed minimal differences between reamed and unreamed specimens, respectively. Conclusion: Mechanical testing identified no statistically significant differences in torsional or compressive properties of our cadaveric tibias after intramedullary reaming. There was a trend towards decreased compressive stiffness, but this is not a common mechanism of fracture. Our findings suggest that the use of the smallest size RIA system in the tibia does not drastically alter the mechanical properties or require prophylactic fixation. The RIA can be used safely as a method of bone graft harvest or intramedullary debridement in the tibia, as long as appropriate technique is used to avoid eccentric reaming or excessive blood loss.

Abstract: Fresh allograft transplantation of osteochondral defects restores functional articular cartilage and subchondral bone; however, rapid loss of chondrocyte viability during storage and osteoclast-mediated bone resorption at the graft–host interface after transplantation negatively impact outcomes. The authors present a pilot study evaluating the in vitro and in vivo impact of augmenting storage media with bisphosphonates. Forty cylindrical osteochondral cores were harvested from femoral condyles of human cadaveric specimens and immersed in either standard storage media or storage media supplemented with nitrogenated or non-nitrogenated bisphosphonates. Maintenance of graft structure and chondrocyte viability were assessed at 3 time points. A miniature swine trochlear defect model was used to evaluate the influence of bisphosphonate-augmented storage media on in vivo incorporation of fresh osteochondral tissue, which was quantified via μCT and decalcified histology. In the in vitro study, Safranin-O/Fast Green staining showed that both low- and high-dose nitrogenated-treated grafts retained chondrocyte viability and cartilage matrix for up to 43 days of storage. Allografts stored in nitrogenated-augmented storage media showed both μCT and histologic evidence of enhanced in vivo bony and cartilaginous incorporation in the miniature swine trochlear defect model. Several preclinical studies have shown the potential for enhanced storage of fresh osteochondral allografts via additions of relatively common drugs and biomolecules. This study showed that supplementing standard storage media with nitrogenated bisphosphonates may improve maintenance of chondrocyte viability and graft structure during cold storage as well as enhance in vivo osseous and cartilaginous incorporation of the graft.

Abstract: WOS: 000342750900005 PubMed: 25243849 Objective: The primary purpose of this study was to determine whether the Sanders computed tomography (CT) scan classification was still prognostic for outcome when long-term (10-20 years) radiographic and functional data of patients after open reduction and internal fixation for Sanders type II versus type III displaced intra-articular calcaneal fractures (DIACFs) were compared. The secondary purpose was to assess whether a bone graft or a locked plate was needed to maintain a reduction over time. Design: Prognostic case-control study. Setting: Level I trauma hospital. Patients: Patients with operatively treated Sanders type II/III DIACF managed between January 1, 1990, and December 31, 2000, by a single surgeon were identified from a prospectively gathered database. Skeletally mature patients with a closed isolated DIACF and a minimum of 10-year follow-up were included in this analysis. All fractures were classified according to Essex-Lopresti and Sanders. Of 638 fractures, 208 met the inclusion criteria. Intervention: Surgery consisted of a lateral extensile approach, posterior facet reduction, and lag screw fixation, followed by reduction of the anterior process and tuberosity with the application of a nonlocked lateral plate. Neither bone graft nor locking plates were used. Main Outcome Measures: Articular congruity and overall reduction were assessed by CT scan and plain radiography (Bohler and Gissane angle) immediately postoperatively and at the final follow-up examination in all patients. Functional assessment and outcome scores were obtained [AOFAS-AHS, the Maryland Foot Score, Short Form-36 (SF-36), Ankle Osteoarthritis Score (AOS), and Visual Analog Scale (VAS)], and all complications and/or subsequent surgeries were noted. A subtalar (ST) arthrodesis was considered a treatment failure and was used as the determining outcome variable for comparing the 2 groups (II vs. III). Results: One hundred eight fractures in 93 patients were available for follow-up at a minimum of 10 years (52%). Average follow-up was 15.22 years (range, 10.5-21.2 years). Eighty were joint depression (J) and 28 were tongue-type (T) fractures. There were 70 Sanders type II and 38 Sanders type III fractures. On immediate postoperative CT scan, posterior facet reduction was anatomic in 103 fractures (95%), near anatomic in 3 fractures (1-3 mm), and approximate in 2 fractures (3-5 mm step). There were no failed reductions (. 5 mm step). Long-term results indicated that only 3 fractures settled, but no plates failed. There was 1 missed peroneal tendon dislocation. Seven patients had sural neuritis. Twelve fractures (11%) required local wound care for apical necrosis. One patient had a dehiscence resulting in osteomyelitis, requiring a ST fusion. Thirty-one fractures (29 patients) developed ST arthritis, requiring an arthrodesis (30 ST, 1 triple) for unrelenting pain (VAS, 8-10) during the follow-up period, resulting in an overall long-term failure rate of 29%. Further breakdown by fracture type revealed that an ST fusion was performed in 47% of type III fractures (18/38) versus only 19% of type II (13/70) fractures (P = 0.002). Type III fractures were 4 times more likely to need a fusion compared with type II fractures (relative risk = 3.94; 95% confidence interval, 1.64-9.48). The remaining 66 patients (77 fractures) who did not require a fusion were evaluated for long-term functional outcome. Of these, only 1 patient used a cane and had a limp. Seventy-seven percent of the nonfused group (51/66) were within the US norm for the SF-36 PCS, with 46% (30/66) above the norm. The average AOFAS-AHS was 75. The average VAS was 1.75, with scores of 0-1 (very little or no pain) seen in 56% of this subset of patients (37/66). Conclusions: Based on the results of this comparative analysis, the Sanders classification remains prognostic; after a minimum of 10 years, type III fractures were 4 times more likely to need a fusion than type II fractures. Secondarily, it seems that neither a locked plate nor a bone graft is required to maintain a reduction over time, as virtually no loss of reduction was seen in this series (3/108, 0.9%). The "joint first" surgical treatment did not adversely affect calcaneocuboid joint outcome. Based on these results, if severe posttraumatic ST arthritis does not occur, long-term (10-20 years) functional results with mild pain, minimal alterations in activities of daily living or work, and essentially normal shoe wear can be expected from a properly performed open reduction and internal fixation. Patients must be counseled regarding difficulty with uneven ground and an inability to return to vigorous sports activities.

Abstract: The DØ experiment enjoyed a very successful data-collection run at the Fermilab Tevatron collider between 1992 and 1996. Since then, the detector has been upgraded to take advantage of improvements to the Tevatron and to enhance its physics capabilities. We describe the new elements of the detector, including the silicon microstrip tracker, central fiber tracker, solenoidal magnet, preshower detectors, forward muon detector, and forward proton detector. The uranium/liquid-argon calorimeters and central muon detector, remaining from Run I, are discussed briefly. We also present the associated electronics, triggering, and data acquisition systems, along with the design and implementation of software specific to DØ. © 2006 Elsevier B.V. All rights reserved.

Abstract: Made available in DSpace on 2022-04-28T20:54:02Z (GMT). No. of bitstreams: 0 Previous issue date: 2009-05-14 We describe a search for production of a charged Higgs boson, qq̄′→H+, reconstructed in the tb̄ final state in the mass range 180≤MH+≤300GeV. The search was undertaken at the Fermilab Tevatron collider with a center-of-mass energy s=1.96TeV and uses 0.9fb-1 of data collected with the D0 detector. We find no evidence for charged Higgs boson production and set upper limits on the production cross section in the types I, II, and III two-Higgs-doublet models (2HDMs). An excluded region in the (MH+, tanβ) plane for type I 2HDM is presented. © 2009 The American Physical Society.

Abstract: Made available in DSpace on 2022-04-28T20:06:00Z (GMT). No. of bitstreams: 0 Previous issue date: 2005-10-07 We have performed a search for neutral Higgs bosons produced in association with bottom quarks in ppÂ collisions, using 260pb-1 of data collected with the D0 detector in Run II of the Fermilab Tevatron Collider. The cross sections for these processes are enhanced in many extensions of the standard model (SM), such as in its minimal supersymmetric extension at large tanâ□¡Î. The results of our analysis agree with expectations from the SM, and we use our measurements to set upper limits on the production of neutral Higgs bosons in the mass range of 90 to 150 GeV. © 2005 The American Physical Society.

Abstract: Background Although early results with reverse total shoulder arthroplasty (rTSA) have been promising, concern exists about the high reported rates of scapular notching and the potential for catastrophic failure of glenoid component fixation. Generation of polyethylene wear debris may also contribute to notching and osteolysis of the scapula. A testing model for polyethylene wear is currently unavailable for reverse shoulder prostheses. The goal of this study was to develop a testing protocol using a commercially available hip simulator. Component design may also influence the generation of polyethylene debris. It is hypothesized that increased polyethylene wear occurs in glenospheres with holes in the articulating surface. Materials and methods Custom fixtures were fabricated to simulate both glenohumeral abduction and flexion on a 12-station hip wear simulator. Loading profiles for both abduction and flexion were alternated every 250,000 cycles for a total of 5 million cycles. Gravimetric analysis of humeral cups throughout the test was used to characterize wear. Lubricant fluid was collected throughout the test and digested for polyethylene particle analysis. Results Comparisons of volumetric wear rates and total volume loss between glenospheres with and without holes and between flexion and abduction loading profiles showed similar results. Particle analysis displayed fibrillar particles with an equivalent circle diameter of 0.3 ± .1 μm and an aspect ratio of 2.5 ± 1.4. Conclusions This study represents the first wear simulation and particle characterization of reverse shoulder systems. No significant difference in wear was reported between glenospheres with and without holes.

Abstract: Background: First generation total ankle arthroplasty (TAA) systems showed high rates of failure. The Agility™ (DePuy, Warsaw, IN) TAA system, a second generation design, had improved outcomes; however, implant failure due to loosening of the metallic components persisted. The purpose of this study was to analyze the damage modes and radiographic mode(s) of failure observed in retrieved Agility™ TAA. Materials and Methods: Ten devices were collected and each component was analyzed for common damage modes using microscopy. Clinical damage was analyzed with postoperative implant and preoperative revision procedure radiographs. Results: Analyses revealed damage/wear to retrieved components, including abrasion, dishing, and pitting. These third-body wear particles may be a precursor to wear debris induced osteolysis which could cause component loosening. Seven TAA systems were removed due to loosening or subsidence, suggesting component damage/wear may lead to clinically observed component loosening. Retrieval analysis indicated the polyethylene experiences edge loading, resulting in increased contact stresses to polyethylene in the primary articulation region and wear. Conclusion: Since poor clinical outcomes have been associated with component instability and osteolysis, analyzing retrieved components wear and damage may be an important step toward improving implant design, thereby decreasing wear debris induced osteolysis and improving clinical outcomes. Level of Evidence: IV, Case Series

Abstract: We report results of a search for the pair production of the lightest supersymmetric partner of the top quark, t ˜ 1 , using a data set corresponding to an integrated luminosity of 1 fb −1 collected by the DO detector at a p p ¯ center-of-mass energy of 1.96 TeV at the Fermilab Tevatron collider. Both scalar top quarks are assumed to decay into a b quark, a charged lepton and a scalar neutrino. The search is performed in the electron plus muon and dielectron final states. The signal topology consists of two isolated leptons, missing transverse energy, and jets. We find no evidence for this process and exclude regions of parameter space in the framework of the minimal supersymmetric standard model.

Abstract: We present a search for a narrow scalar or vector resonance decaying into Z gamma with a subsequent Z boson decay into a pair of electrons or moons. The data for this search were collected with the D circle divide detecror at the Fermilab Tevatron p (p) over bar collider at a center of mass energy root s = 1.96 TeV. Using 1.1 (1.0) fb(-1) of data, we observe 49 (50) candidate events in the electron (muon) channel, in good agreement with the standard model prediction. From the combination of both channels, we derive 95% C.L. upper limits on the cross section times branching fraction (sigma x B) into Z gamma. These limits range from 0.19 (0.20) pb for a scalar (vector) resonance mass of 600 GeV/c(2) to 2.5 (3.1) pb for a mass of 140 GeV/c(2).

Abstract: We present a search for a narrow-width heavy resonance decaying into top quark pairs X->ttbar in ppbar collisions at sqrt{s}=1.96TeV using approximately 0.9fb^-1 of data collected with the D0 detector at the Fermilab Tevatron Collider. This analysis considers ttbar candidate events in the lepton plus jets channel with at least one identified b jet and uses the ttbar invariant mass distribution to search for evidence of resonant production. We find no evidence for a narrow resonance X decaying to ttbar. Therefore, we set upper limits on sigma*B(X->ttbar) for different hypothesized resonance masses using a Bayesian approach. For a Topcolor-assisted technicolor model, the existence of a leptophobic Z' boson with mass M_Z'

Abstract: We present a measurement of the fraction of inclusive W +jets events produced with net charm quantum number 11, denoted W + c-jet, in p collisions at root s = 1.96 TeV using approximately 1 fb(-1) of data collected by the DO detector at the Fermilab Tevatron Collider. We identify the W +jets events via the leptonic W boson decays. Candidate W + c-jet events are selected by requiring a jet containing a muon in association with a reconstructed W boson and exploiting the charge correlation between this muon and W boson decay lepton to perform a nearly model-independent background subtraction. We measure the fraction of W + c-jet events in the inclusive W +jets sample for jet PT > 20 GeV and pseudorapidity |eta| < 2.5 to be 0.074 +/- 0.019(stat.) +/-(0.012)(0.014) (syst.), in agreement with theoretical predictions. The probability that background fluctuations could produce the observed fraction of W + c-jet events is estimated to be 2.5 x 10(-4), which corresponds to a 3.5 sigma statistical significance.

26. Plasma flow induced local variation of dispersion constants of ITO‐films observed with spectroscopic imaging ellipsometry

Abstract: The influence of the intentionally inhomogeneous plasma flow on the spatial distribution of the ITO optical properties has been investigated. The oscillator force has a minimum at low plasma flow and maxima at the high plasma flow regions of the sample. The free electron density increases at the edges of the wafer compared to the low plasma flow area of the sample. The changes are explained by varying the film microstructure and stoichiometry on macro- and microscopic scales. (© 2008 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim)

Abstract: We present new results of the search for WH→ℓνbb¯ production in pp¯ collisions at a center-of-mass energy of s=1.96 TeV, based on a dataset with integrated luminosity of 0.44 fb−1. We combine these new results with previously published searches by the D0 collaboration, for WH and ZH production analyzed in the E̸Tbb¯ final state, for ZH (→ℓ+ℓ−bb¯) production, for WH (→WWW) production, and for H (→WW) direct production. No signal-like excess is observed either in the WH analysis or in the combination of all D0 Higgs boson analyses. We set 95% C.L. (expected) upper limits on σ(pp¯→WH)×B(H→bb¯) ranging from 1.6 (2.2) pb to 1.9 (3.3) pb for Higgs boson masses between 105 and 145 GeV, to be compared to the theoretical prediction of 0.13 pb for a Standard Model (SM) Higgs boson with mass mH=115 GeV. After combination with the other D0 Higgs boson searches, we obtain for mH=115 GeV an observed (expected) limit 8.5 (12.1) times higher than the SM predicted Higgs boson production cross section. For mH=160 GeV, the corresponding observed (expected) ratio is 10.2 (9.0).

Abstract: The method of of imaging spectroscopic ellipsometry is applied on magnetic read/write heads of hard disks. By means of spectroscopic ellipsometry, an optical model of the TiC/Al 2 O 3 substrate including surface roughness and concentration gradient of TiC in the alumina substrate is generated. Surface roughness is measured with both ellipsoametry and atomic force microscopy (AFM). The granular structure of TiC/Al 2 O 3 is investigated in micrographs of n and k. It is discussed how Delta mapping of the magnetic pole area of the head can be used to measure DLC coating thickness and the variation of chemical constitution of the metal substrate. Repeatability of measurements of Delta is optimized in a one μm 2 region of interest (ROI) on a metal stripe of the magnetic pole.

Abstract: A data sample corresponding to an integrated luminosity of 2.1 fb(-1) collected by the D phi detector at the Fermilab Tevatron Collider was analyzed to search for squarks and gluinos produced in p (p) over bar collisions at a center-of-mass energy of 1.96 TeV. No evidence for the production of such particles was observed in topologies involving jets and missing transverse energy, and 95% C.L. lower limits of 379 GeV and 308 GeV were set on the squark and gluino masses, respectively, within the framework of minimal supergravity with tan beta = 3, A(0) = 0, and mu < 0. The corresponding previous limits are improved by 54 GeV and 67 GeV.

Abstract: We present a study of events with Z bosons and jets produced at the Fermilab Tevatron Collider in ppbar collisions at a center of mass energy of 1.96 TeV. The data sample consists of nearly 14,000 Z/G* -> e+e- candidates corresponding to the integrated luminosity of 340 pb-1 collected using the D0 detector. Ratios of the Z/G* + >= n jet cross sections to the total inclusive Z/G* cross section have been measured for n = 1 to 4 jet events. Our measurements are found to be in good agreement with a next-to-leading order QCD calculation and with a tree-level QCD prediction with parton shower simulation and hadronization.

Abstract: We present a study of eey and mu mu gamma events using 1109 (1009) pb-(1) of data in the electron (muon) channel, respectively. These data were collected with the DO detector at the Fermilab Tevatron pp collider at Is = 1.96 TeV. Having observed 453 (515) candidates in the eey (jtAy) final state, we measure the Z gamma production cross section for a photon with transverse energy ET > 7 GeV, separation between the photon and leptons Delta Rey > 0.7, and invariant mass of the di-lepton pair Mee > 30 GeV/(2)(c), to be 4.96 0.30(stat. + syst.) zE 0.30(lumi.) pb, in agreement with the Standard Model prediction of 4.74 0.22 pb. This is the most precise Zy cross section measurement at a hadron collider. We set limits on anomalous trilinear Zyy and ZZy gauge boson couplings of -0.085 < h(30)(y) < 0.084, -0.0053 < h(40)(y) < 0.0054 and -0.083 < h(30)(Z) < 0.082, 30 40 30 -0.0053 < h(40)(Z) < 0.0054 at the 95% C.L. for the form-factor scale A = 1.2 TeV. 40 .

Abstract: We report on a search for second generation leptoquarks LQ_2 which decay into a muon plus quark in p\bar{p} collisions at a center-of-mass energy of sqrt{s} = 1.96 TeV in the D0 detector using an integrated luminosity of about 300 pb-1. No evidence for a leptoquark signal is observed and an upper bound on the product of the cross section for single leptoquark production times branching fraction beta into a quark and a muon was determined for second generation scalar leptoquarks as a function of the leptoquark mass. This result has been combined with a previously published D0 search for leptoquark pair production to obtain leptoquark mass limits as a function of the leptoquark-muon-quark coupling, lambda. Assuming lambda=1, lower limits on the mass of a second generation scalar leptoquark are m{LQ_2}>274 GeV and m{LQ_2}>226 GeV for beta=1 and beta=1/2, respectively.

Abstract: A search for the pair production of scalar top quarks, {bar t}, has been performed in 360 pb{sup -1} of data from p{bar p} collisions at a center-of-mass energy of 1.96 TeV, collected by the D0 detector at the Fermilab Tevatron collider. The {bar t} decay mode considered is {bar t} {yields} c{bar {chi}}{sub 1}{sup 0}, where {bar {chi}}{sub 1}{sup 0} is the lightest supersymmetric particle. The topology analyzed therefore consists of a pair of acoplanar heavy-flavor jets with missing transverse energy. The data show good agreement with the standard model expectation, and a 95% C.L. exclusion domain in the (m{sub {tilde t}}, m{sub {tilde {chi}}{sub 1}{sup 0}}) plane has been determined, extending the domain excluded by previous experiments.

Abstract: We describe a search for the Standard Model Higgs boson with a mass of 105 GeV/c(2) to 145 GeV/c(2) in data corresponding to an integrated luminosity of approximately 450 pb(-1) collected with the D phi detector at the Fermilab Tevatron p (p) over bar collider at a center-of-mass energy of 1.96 TeV. The Higgs boson is required to be produced in association with a Z boson, and the Z boson is required to decay to either electrons or muons with the Higgs boson decaying to a b (b) over bar pair. The data are well described by the expected background, leading to 95% confidence level cross section upper limits sigma (p (p) over bar -> ZH) x B(H -> b (b) over bar) in the range of 3.1 pb to 4.4 pb.

Abstract: We present the results of a search for a new particle X produced in p p ¯ collisions at s = 1.96 TeV and subsequently decaying to Zγ. The search uses 0.3 fb−1 of data collected with the DO detector at the Fermilab Tevatron Collider. We set limits on the production cross section times the branching fraction σ ( p p ¯ → X ) × B ( X → Z γ ) that range from 0.4 to 3.5 pb at the 95% C.L. for X with invariant masses between 100 and 1000 GeV / c 2 , over a wide range of X decay widths.

Abstract: We present a search for the production of a new heavy gauge boson W' that decays to a top quark and a bottom quark. We have analyzed 230 pb(-1) of data collected with the DO detector at the Fermilab Tevatron collider at a center-of-mass energy of 1.96 TeV. No significant excess of events above the standard model expectation is found in any region of the final state invariant mass distribution. We set upper limits on the production cross section of W' bosons times branching ratio to top quarks at the 95% confidence level for several different W, boson masses. We exclude masses between 200 and 610 GeV for a W' boson with standard-model-like couplings, between 200 and 630 GeV for a W, boson with right-handed couplings that is allowed to decay to both leptons and quarks, and between 200 and 670 GeV for a W' boson with right-handed couplings that is only allowed to decay to quarks.

Abstract: A search for leptoquarks has been performed in 310 pb{sup -1} of data from p{bar p} collisions at a center-of-mass energy of 1.96 TeV, collected by the D0 detector at the Fermilab Tevatron Collider. The topology analyzed consists of acoplanar jets with missing transverse energy. The data show good agreement with standard model expectations, and a lower mass limit of 136 GeV has been set at the 95% C.L. for a scalar leptoquark decaying exclusively into a quark and a neutrino.

Abstract: We present the measurement of R = B(t -> Wb)/B(t -> Wq) in pp collisions at root s = 1.96 TeV, using 230 pb(-1) of data collected by the DO experiment at the Fermilab Tevatron Collider. We fit simultaneously R and the number (N-tt) of selected top quark pairs (tt), to the number of identified b-quark jets in events with one electron or one muon, three or more jets, and high transverse energy imbalance. To improve sensitivity, kinematical properties of events with no identified b-quark jets are included in the fit. We measure R = 1.03(-0.17)(0.19) (stat + syst), in good agreement with the standard model. We set lower limits of R > 0.61 and vertical bar V-tb vertical bar > 0.78 at 95% confidence level.

Abstract: The results of a search for squarks and gluinos using data from p p ¯ collisions recorded at a center-of-mass energy of 1.96 TeV by the DO detector at the Fermilab Tevatron Collider are reported. The topologies analyzed consist of acoplanar-jet and multijet events with large missing transverse energy. No evidence for the production of squarks or gluinos was found in a data sample of 310 pb−1. Lower limits of 325 and 241 GeV were derived at the 95% C.L. on the squark and gluino masses, respectively, within the framework of minimal supergravity with tan β = 3 , A 0 = 0 , and μ 0 .

Abstract: We report on a search for the pair production of second generation scalar leptoquarks (LQ_2) in ppbar collisions at the center-of-mass energy sqrt(s) = 1.96 TeV, using data corresponding to an integrated luminosity of 294 +- 19 pb^-1 recorded with the D0 detector. No evidence for a leptoquark signal in the LQ_2 LQ_2 -> muq muq channel has been observed, and upper bounds on the product of cross section times branching fraction were set. This yields lower mass limits of m(LQ_2) > 247 GeV for beta = Br(LQ_2->muq) = 1 and m(LQ_2) > 182 GeV for beta = 1/2. Combining these limits with previous D0 results, the lower limits on the mass of a second generation scalar leptoquark are m(LQ_2) > 251 GeV and m(LQ_2) > 204 GeV for beta = 1 and beta = 1/2, respectively.

Abstract: We present a search for electroweak production of single top quarks in the s-channel and t-channel using neural networks for signal-background separation. We have analyzed 230 pb(-1) of data collected with the DO detector at the Fermilab Tevatron Collider at a center-of-mass energy of 1.96 TeV and find no evidence for a single top quark signal. The resulting 95% confidence level upper limits on the single top quark production cross sections are 6.4 pb in the s-channel and 5.0 ph in the t-channel. (c) 2005 Elsevier B.V. All rights reserved.

44. Limites quantiques de résolution et structures transverses classiques dans un oscillateur paramétrique optique

Author: Claude Fabre, M. Vaupel, Nicolas Treps, and Agnès Maître
Subjects: General Physics and Astronomy
Abstract: Le bruit de grenaille est considere comme une limite fondamentale a la resolution des images optiques classiques. En fait, il est possible de passer au dela de cette limite en utilisant des etats multimodes non classiques de la lumiere. Un Oscillateur Parametrique Optique (OPO) degenere en modes transverses peut permettre de generer de tels etats. En particulier, dans des mesures de petits deplacements de faisceaux, un OPO concentrique peut permettre d'obtenir une resolution superieure a la limite quantique standard. Un oscillateur parametrique confocal degenere en frequence permet d'emettre des faisceaux multimodes dont le bruit local est inferieur au bruit de grenaille. L'experience presentee ici cherche a mettre en evidence de tels etats. Les faisceaux classiques emis resultent de l'interaction non-lineaire d'un grand nombre de modes transverses, condition necessaire pour observer les etats multimodes non-classiques.

Abstract: We have observed transverse pattern formation in a near-confocal, type II, triply resonant optical parametric oscillator (OPO) operating close to frequency degeneracy for the signal and idler modes. In the region of observation of these patterns, the OPO oscillation threshold increases. Complex ring patterns and latticelike structures are observed. These patterns are due to the nonlinear coupling of many transverse modes (on the order of 25). The transverse distribution of the light is different in the signal, idler, and transmitted pump modes.

Abstract: We report on the detection of matching effects between antidot and vortex lattices in rf SQUIDs that clearly demonstrate, that antidots can strongly reduce the low-frequency 1/f noise in active superconducting devices. Square lattices of holes (antidots) with diameters of 0.25-2 /spl mu/m and lattice parameters ranging from 0.5 to 50 /spl mu/m are patterned into optimized sputtered YBa/sub 2/Cu/sub 2/O/sub 7-/spl delta// thin films without deterioration of superconducting properties. First, a special experimental set-up consisting of an antidot lattice in flip-chip configuration with a bicrystal rf-SQUID is used for the demonstration of the principle of noise reduction by antidots. Matching effects between vortex and antidot lattice in form of minima in the noise spectra are observed, indicating that thermally activated hopping of vortices can strongly be reduced by antidots. Second, antidots are directly patterned into step-edge rf-SQUIDs. For large antidot lattice parameters (50 /spl mu/m) no degradation of the SQUID parameters can be measured. However, matching effects and noise reduction due to the presence of the antidots can not be observed in this first attempt. The results are discussed in terms of multiquanta, possible solutions and suggestions for improvements are given.

Author: M Vaupel
Subjects: Materials science, business.industry, General Mathematics, Applied Mathematics, Isotropy, General Physics and Astronomy, Frequency shift, Statistical and Nonlinear Physics, Self-focusing, Photorefractive effect, Condensed Matter::Materials Science, Optics, Saturation (chemistry), business, Anisotropy, Beam (structure), Mixing (physics)
Abstract: Self-focusing and -defocusing of light in two-wave mixing is investigatedexperimentally for BaTiO3 and BSO. Amplification and self-focusing of a probe beamare measured as functions of the frequency shift between probe and pump beam. The self-focusingin two-wave mixing in BSO is anisotropic, whereas it is isotropic in BaTiO3.Consequences of gain saturation for the measurement of self-focusing in BaTiO3 arediscussed.

Abstract: We derive a nonlinear wave equation for a signal beam which is coupled to a pump beam by two-wave-mixing in a photorefractive crystal. This equation describes self-focusing of the signal beam. We compare two-wave-mixing induced spatial self-focusing of single-pass experiments in a diffusion-type photorefractive crystal and of a photorefractive oscillator using the same crystal. We observe that the nonlinear refractive index change in the oscillator is decreased while increasing resonator losses.

50. Cross-phase-modulation–induced self-focusing in parametric oscillators

Author: O. Mandel and M. Vaupel
Subjects: Physics, business.industry, Cross-phase modulation, Physics::Optics, General Physics and Astronomy, Self-focusing, Photorefractive effect, Transverse mode, Resonator, Laser linewidth, Optics, Parametric oscillator, Self-phase modulation, business
Abstract: The dependence of spatial self-focusing on resonator detuning is experimentally investigated in the active medium of a photorefractive oscillator which is a parametric oscillator with narrow gain linewidth. Beam diameter of the TEM00-mode and beat frequency of the TEM00-mode and another simultaneously emitted transverse mode depend on detuning like a dispersion-shaped function. The maximum strength of self-focusing and the corresponding frequency shift are in the resonator strongly reduced with respect to single-pass wave mixing.
