Degraded broadcast channels (DBC) are a typical multi-user communications scenario. There exist classic transmission methods, such as superposition coding with successive interference cancellation, to achieve the DBC capacity region. However, semantic communications method over DBC remains lack of in-depth research. To address this, we design a fusion-based multi-user semantic communications system for wireless image transmission over DBC in this paper. The proposed architecture supports a transmitter extracting semantic features for two users separately, and learns to dynamically fuse these semantic features into a joint latent representation for broadcasting. The key here is to design a flexible image semantic fusion (FISF) module to fuse the semantic features of two users, and to use a multi-layer perceptron (MLP) based neural network to adjust the weights of different user semantic features for flexible adaptability to different users channels. Experiments present the semantic performance region based on the peak signal-to-noise ratio (PSNR) of both users, and show that the proposed system dominates the traditional methods.

Diffusion models (DMs) have recently been introduced in image deblurring and exhibited promising performance, particularly in terms of details reconstruction. However, the diffusion model requires a large number of inference iterations to recover the clean image from pure Gaussian noise, which consumes massive computational resources. Moreover, the distribution synthesized by the diffusion model is often misaligned with the target results, leading to restrictions in distortion-based metrics. To address the above issues, we propose the Hierarchical Integration Diffusion Model (HI-Diff), for realistic image deblurring. Specifically, we perform the DM in a highly compacted latent space to generate the prior feature for the deblurring process. The deblurring process is implemented by a regression-based method to obtain better distortion accuracy. Meanwhile, the highly compact latent space ensures the efficiency of the DM. Furthermore, we design the hierarchical integration module to fuse the prior into the regression-based model from multiple scales, enabling better generalization in complex blurry scenarios. Comprehensive experiments on synthetic and real-world blur datasets demonstrate that our HI-Diff outperforms state-of-the-art methods.

BACKGROUND Fetus-in-fetu (FIF) is an extremely rare congenital abnormal mass, in which a normal fetus’s vertebral axis frequently connected with malformed fetus around this axis. Here, we report the case of a male infant aged 26 d presenting with retroperitoneal parasitic fetus. CASE SUMMARY In a prenatal examination, we first detected an abdominal mass measuring 7.8 cm × 5.1 cm × 6.8 cm in a mother’s abdomen at 25 gestational weeks and teratoma was suspected. After the fetal was born, we did a magnetic resonance imaging (MRI) and ultrasonography on him and saw a distinctive limb with five-toes. According to the result of MRI, ultrasonography and postoperative pathology, he finally was diagnosed with FIF. CONCLUSION A laparotomy was performed at 26 d of age with excision of the retroperitoneal cystic tumor, which measured about 10 cm in diameter. According to the result of imaging and histological test, FIF was confirmed.

This paper aims to explore the feasibility of the spectrum sharing between the communication and radar system. We investigate the full-duplex (FD) joint radar and communication multi-antenna system in which a node labeled ComRad with a dual communication and radar capability is communicating with a downlink and an uplink users, as well as detecting the target of interest simultaneously. Considering a full interference scenario and imperfect channel state information (CSI), the fundamental performance limits of the FD JRC system are analyzed. In particular, we first obtain the downlink rate when the radar signals act as interference. Then, viewing the uplink channel and radar return channel as a multiple access channel, we propose an alternative successive interference cancellation scheme, based on which the achievable uplink communication rate is obtained. For the radar operation, we first derive the general expression of the estimation rate, which quantifies how much information is obtained about the target in terms of the direction, the range and the velocity. Considering the uniform linear antenna array and linear frequency modulated radar signals, we further obtain the exact closed-form estimation rate. Numerical simulations reveal that the joint manner of the communication and radar operations achieves larger rate regions compared to that of working independently., Comment: 31 pages, 9 figures, Accepted by China Communication

FOS: Computer and information sciences ,Computer Vision and Pattern Recognition (cs.CV) ,Computer Science - Computer Vision and Pattern Recognition - Abstract
Image harmonization aims to achieve visual consistency in composite images by adapting a foreground to make it compatible with a background. However, existing methods always only use the real image as the positive sample to guide the training, and at most introduce the corresponding composite image as a single negative sample for an auxiliary constraint, which leads to limited distortion knowledge, and further causes a too large solution space, making the generated harmonized image distorted. Besides, none of them jointly constrain from the foreground self-style and foreground-background style consistency, which exacerbates this problem. Moreover, recent region-aware adaptive instance normalization achieves great success but only considers the global background feature distribution, making the aligned foreground feature distribution biased. To address these issues, we propose a self-consistent style contrastive learning scheme (SCS-Co). By dynamically generating multiple negative samples, our SCS-Co can learn more distortion knowledge and well regularize the generated harmonized image in the style representation space from two aspects of the foreground self-style and foreground-background style consistency, leading to a more photorealistic visual result. In addition, we propose a background-attentional adaptive instance normalization (BAIN) to achieve an attention-weighted background feature distribution according to the foreground-background feature similarity. Experiments demonstrate the superiority of our method over other state-of-the-art methods in both quantitative comparison and visual analysis., Comment: Accepted by CVPR 2022

The high computational costs of video super-resolution (VSR) models hinder their deployment on resource-limited devices, (e.g., smartphones and drones). Existing VSR models contain considerable redundant filters, which drag down the inference efficiency. To prune these unimportant filters, we develop a structured pruning scheme called Structured Sparsity Learning (SSL) according to the properties of VSR. In SSL, we design pruning schemes for several key components in VSR models, including residual blocks, recurrent networks, and upsampling networks. Specifically, we develop a Residual Sparsity Connection (RSC) scheme for residual blocks of recurrent networks to liberate pruning restrictions and preserve the restoration information. For upsampling networks, we design a pixel-shuffle pruning scheme to guarantee the accuracy of feature channel-space conversion. In addition, we observe that pruning error would be amplified as the hidden states propagate along with recurrent networks. To alleviate the issue, we design Temporal Finetuning (TF). Extensive experiments show that SSL can significantly outperform recent methods quantitatively and qualitatively., Comment: Accepted by CVPR2023, code is available at https://github.com/Zj-BinXia/SSL

Papillary thyroid carcinoma (PTC) is the most common malignancy of the thyroid gland, with a relatively high cure rate. Distant metastasis (DM) of PTC is uncommon, but when it occurs, it significantly decreases the survival of PTC patients. The molecular mechanisms of DM in PTC have not been systematically studied. We performed whole exome sequencing and GeneseeqPrime (425 genes) panel sequencing of the primary tumor, plasma and matched white blood cell samples from 20 PTC with DM and 46 PTC without DM. We identified somatic mutations, gene fusions and copy number alterations and analyzed their relationships with DM of PTC. BRAF‐V600E was identified in 73% of PTC, followed by RET fusions (14%) in a mutually exclusive manner (P < 0.0001). We found that gene fusions (RET, ALK or NTRK1) (P < 0.01) and chromosome 22q loss (P < 0.01) were independently associated with DM in both univariate and multivariate analyses. A nomogram model consisting of chromosome 22q loss, gene fusions and three clinical variables was built for predicting DM in PTC (C‐index = 0.89). The plasma circulating tumor DNA (ctDNA) detection rate in PTC was only 38.9%; however, it was significantly associated with the metastatic status (P = 0.04), tumor size (P = 0.001) and invasiveness (P = 0.01). In conclusion, gene fusions and chromosome 22q loss were independently associated with DM in PTC and could serve as molecular biomarkers for predicting DM. The ctDNA detection rate was low in non–DM PTC but significantly higher in PTC with DM., The study identified gene fusion and somatic copy number alterations, particularly chromosome 22q loss, to be risk factors for distance metastasis (DM) of PTC and provided a convenient tool for the prediction of PTC DM.

Delayed tooth development (DTD) is the development progress of a tooth germ that takes place later due to local or general causes. This case report reviews a 16-year-old Asian adolescent whose bilateral upper second premolar germs were at Nolla’s 6 stage as shown on a panoramic radiograph. It is unusual that tooth germs of the maxillary second premolar are developed after 11 years of age. To reduce the chance of misdiagnosis, clinicians should consider the possibility of DTD if a tooth germ does not present in radiographs.

The conserved microRNA396 (miR396) is involved in growth, development, and abiotic stress responses in a variety of plants by regulating target genes. Here, we obtained transgenic Chrysanthemum indicum (C. indicum) overexpressing the cin-miR396a gene. The transgenic plants (TGs) had longer internodes and fewer epidermal hairs in contrast with the wild-type (WT) control. cin-miR396a overexpression in C. indicum reduced salt tolerance and drought tolerance. After salt and drought stress compared with WT plants, the transgenic C. indicum exhibited a relative decrease in leaf water content, and the leaf free proline content, also exhibited a relative increase, in the leaf conductivity and leaf Malondialdehyde content, while the total chlorophyll content did not differ significantly from WT, and the Na+/K+ ratio in the roots of transgenic C. indicum increased after salt stress. We also identified two target genes of cin-miR396a, CiGRF1 and CiGRF5, whose expression was induced by salt and drought treatments and suppressed in transgenic C. indicum. Taken together, our results reveal a unique role for the regulatory module of miR396a-GRFs in C. indicum development and response to abiotic stresses. cin-miR396a plays a negative regulatory role in C. indicum in response to salt and drought stresses.

Diabetic retinopathy (DR) diagnosis methods in the literature are usually criticized as being limit in diagnosing DR-related features or being lack of interpretability. To deal with these issues, this paper investigates the feasibility of diagnosing both DR severity levels and the presence of DR-related features in a two-step procedure. Specifically, this paper first analyzes the quality of annotations in DR grading by measuring inter-grader variability. Cosine similarity is considered to evaluate the inter-grader variability of the presence of DR-related features, and quadratic weighted Cohen's kappa is employed to assess the inter-grader variability of DR severity levels. Next, different annotation methods as follows are compared to DR severity prediction performance using logistic regression: 1) single annotations by single grader (SASG); 2) single annotations from multiple graders (SAMG); 3) multiple annotations by voting (MAV); and 4) double annotations with adjudication of disagreement (DAAD). Based on the comparison results, the feasibility of diagnosing both DR severity and features is investigated. In the experiments, 1589 fundus images graded by three retinal specialists and four general ophthalmologists are considered. The results demonstrate that retinal specialists are more consistent than general ophthalmologists in grading both the presence of DR-related features and DR severity. The SASG and MAV should be avoided if possible while the DAAD is the good option when prediction performance is the highest priority and the SAMG is especially beneficial when both prediction performance and grading costs are considered. The upper limit performance of DR severity prediction gets accuracy 95.6% and kappa 0.962. When DR-related feature prediction achieves average cosine similarity 0.823, it is potential to get accuracy 91.2% and kappa 0.905 for DR severity prediction in real applications. These results together suggest the potential of diagnosis of both DR severity and the presence of DR-related features in a two-step procedure.

Some thyroid carcinomas (TCs) have an aggressive biological behavior and poor prognosis, and lacking of effective molecular markers is still the main obstacle for clinical stratified diagnosis and treatment of TC. The aim of the study was to discover the clinicopathological and prognostic implications of Src homology region 2-containing protein tyrosine phosphatase 2 (SHP2) and Hook microtubule tethering protein 1 (Hook1) expression in TC. The expression of SHP2 and Hook1 was detected by immunohistochemistry on tissue microarrays from 313 primary TCs who underwent surgery in January 2006 and January 2010 in Zhejiang Cancer Hospital. The χ2 test, Kaplan-Meier method, and Cox proportional-hazards regression models were used to analyze the associations between their expressions and clinicopathological features and prognosis. The expression rates of SHP2 and Hook1 in TC were 57.5% (180/313) and 22.0% (69/313), respectively. SHP2 was positively correlated with Hook1 in TC. SHP2 expression differed significantly by age, histologic variants, maximal tumor diameter, intrathyroidal dissemination, metastases, and disease stage (P .05). Our results suggested that SHP2 may be a favorable indicator of prognosis in TC.

This paper presents a weakly supervised image segmentation method that adopts tight bounding box annotations. It proposes generalized multiple instance learning (MIL) and smooth maximum approximation to integrate the bounding box tightness prior into the deep neural network in an end-to-end manner. In generalized MIL, positive bags are defined by parallel crossing lines with a set of different angles, and negative bags are defined as individual pixels outside of any bounding boxes. Two variants of smooth maximum approximation, i.e., $\alpha$-softmax function and $\alpha$-quasimax function, are exploited to conquer the numeral instability introduced by maximum function of bag prediction. The proposed approach was evaluated on two pubic medical datasets using Dice coefficient. The results demonstrate that it outperforms the state-of-the-art methods.

In this letter, we propose a semantic communication scheme for wireless relay channels based on Autoencoder, named AESC, which encodes and decodes sentences from the semantic dimension. The Autoencoder module provides anti-noise performance for the system. Meanwhile, a novel semantic forward (SF) mode is designed for the relay node to forward the semantic information at the semantic level, especially for the scenarios that there is no common knowledge shared between the source and destination nodes. Numerical results show that the AESC achieves better stability performance than the traditional communication schemes, and the proposed SF mode provides a significant performance gain compared to the traditional forward protocols., Comment: submitted to IEEE Communication Letters

Deep learning methods for diabetic retinopathy (DR) diagnosis are usually criticized as being lack of interpretability in the diagnostic result, thus limiting their application in clinic. Simultaneous prediction of DR related features during the DR severity diagnosis is able to resolve this issue by providing supporting evidence (i.e. DR related features) for the diagnostic result (i.e. DR severity). In this study, we propose a hierarchical multi-task deep learning framework for simultaneous diagnosis of DR severity and DR related features in fundus images. A hierarchical structure is introduced to incorporate the casual relationship between DR related features and DR severity levels. In the experiments, the proposed approach was evaluated on two independent testing sets using quadratic weighted Cohen's kappa coefficient, receiver operating characteristic analysis, and precision-recall analysis. A grader study was also conducted to compare the performance of the proposed approach with those of general ophthalmologists with different levels of experience. The results demonstrate that the proposed approach could improve the performance for both DR severity diagnosis and DR related feature detection when comparing with the traditional deep learning-based methods. It achieves performance close to general ophthalmologists with five years of experience when diagnosing DR severity levels, and general ophthalmologists with ten years of experience for referable DR detection.

Background During the process of shearing the ligamentum flavum, rotating the working channel, and manipulating the annulus fibrosis, the sinuvertebral nerve and the spinal nerve root can be irritated, inducing intolerable back and leg pain. Thus, general anesthesia is recommended and well accepted by most surgeons when performing percutaneous endoscopic lumbar discectomy (PELD) via the interlaminar approach. The aim of our study was to explore the efficacy and safety of percutaneous endoscopy interlaminar lumbar discectomy with gradient local anesthesia (LA) in patients with L5/S1 disc herniation. Methods This retrospective study was conducted between December 2017 and June 2018. The study included 50 consecutive patients who met the study criteria, had single-level L5/S1 disc herniation, and underwent PELD via the interlaminar approach under gradient LA. Different concentrations of local anesthetic compound (LAC) were injected into different tissues inside and outside the ligamentum flavum to complete gradient LA. The evaluation criteria included the intraoperative satisfaction score, visual analog scale (VAS) score, Oswestry Disability Index (ODI), complications, and adverse reactions. Results The intraoperative satisfaction score was consistently over 7, with an average score of 9.3 ± 0.7, indicating that LAC can achieve satisfactory pain control throughout the PELD operation without additional anesthesia. The postoperative VAS score and ODI were dramatically improved at each follow-up interval (P < 0.001, respectively). There was no serious complication such as dural rupture caused by puncture, dural laceration caused by manipulation under endoscopy, total spinal anesthesia, iatrogenic nerve root injury, epidural hematoma, infections, or local anesthetic-related adverse reactions. Three patients experienced transient postoperative dysesthesia of the lower limbs that gradually recovered within 24 h. Conclusions Gradient local anesthesia can satisfactorily and safely control intraoperative pain during the PELD via the interlaminar approach. It can not only improve intraoperative satisfaction, but also reduce local anesthesia-related adverse reactions and surgery-related complications.

Background: Dental plaque is the cause of many common oral diseases (e.g., caries, gingivitis, and periodontitis). Therefore, the detection and control of dental plaque are of great significance to children’s oral health. The objectives of this study are to design an artificial intelligence (AI) model based on deep learning to detect dental plaque on primary teeth and evaluate the diagnostic accuracy of the AI model.Methods: A conventional neural network (CNN) framework was adopted, and a total of 886 photos of primary teeth taken by an intraoral camera (1280×960 pixels; TPC Ligang, Shenzhen, China) were used to train the AI model. To validate the clinical feasibility, 98 photos of primary teeth taken by the intraoral camera were assessed by the AI model. Additionally, tooth photos were acquired using a digital camera (3216×2136 pixels, Canon EOS 60D, Japan). One experienced pediatric dentist looked at these photos and marked the regions the photos containing dental plaque. Then, a plaque-disclosing agent was applied, and the areas of dental plaque were identified. After a week, the dentist drew the dental plaque area on the 98 photos taken by the digital camera a second time to evaluate the consistency of manual diagnosis. In another round of comparison, 102 photos of primary teeth taken by the same intraoral camera were marked to denote the dental plaque area obtained both by the AI model and by the pediatric dentist to evaluate the diagnostic ability of each approach based on photos with lower-resolution (fewer pixels) than those taken by the digital camera. The mean intersection-over-union (MIoU) metric was employed to indicate the detection accuracy.Results: The MIoU for the detection of dental plaque on the tested tooth photos was 0.726 ± 0.165.The MIoU of the dentist when diagnosing the 98 photos taken by the digital camera for the first time was 0.695 ± 0.269, while after one week, the MIoU of the dentist was 0.689 ± 0.253. Compared to the dentist, the AI model demonstrated a higher MIoU (0.736 ± 0.174), and the results did not change after a week. When both the dentist and the AI model assessed the 102 photos taken by the intraoral camera. the MIoU of the pediatric dentist was 0.652 ± 0.195, and the MIoU of the AI model was 0.724 ±0.159. The results of a paired t-test found no significant difference between the AI model and human specialist (P > .05) in diagnosing dental plaque on primary teeth.Conclusions: The AI model showed clinically acceptable performance in detecting dental plaque on primary teeth compared with an experienced pediatric dentist. This finding illustrates the potential application in adopting such AI technology for helping children improve their oral health.

In this article, two Ba(II) metal-organic frameworks(MOFs), {[Ba(BPS)(H2O)2]·H2O}n(1) and [Ba(BPS)(H2O)2]n(2)(H2BPS=4,4′-bibenzoic acid-2,2′-sulfone), were synthesized and characterized. X-Ray crystal structural analyses reveal that compounds 1 and 2 have different structures, which is probably related to different coordination modes of ligand in compounds 1 and 2. It is remarkable that compounds 1 and 2 both show excellent thermal stability. The solid-state emission spectra reveal that compounds 1 and 2 both present strong luminescence emission bands at room temperature.

Service providers are transferring their static optical transport networks from semi-permanent connections to agile automatic switched optical networks (ASON) with dynamic optical connection provisioning and restoration. To achieve this goal, service providers are looking for flexible optical network ROADMs with CDC capabilities. Although many contention scenarios during network connection provisioning and restoration have been illustrated, surprisingly academic simulations have showed that the blocking probability improvement of CDC ROADM comparing with CD ROADM is not significant. This is good news for service providers since most deployed optical networks are only CD ROADM capable, instead of CDC ROADM capable. How to make use of existing CD ROADMs to achieve network automation becomes an urgent challenge. In this paper, we present two research results to attack this challenge: (1) first, we built an analytical mode to estimate the CD ROADM contention blocking probability and show that when a CD ROADM add/drop local direction capacity occupation ratio is low or moderate, the contention blocking probability is not significant. From this model, we estimate that one can use a CD add/drop local direction capacity occupation ratio up to 75% before installing another CD ROADM add/drop local direction or installing a CDC add/drop local direction when available. Simulation results on real network topologies and traffic matrices verified our recommendation; (2) second, we observed that most deployed optical networks are usually providing 100G or 200G per wavelength while majority applications are still requesting much smaller bandwidths and service providers often provide OTN (Optical Transport Network) over ROADM architecture for transport services. Since OTN provides electronic switching capability, in this paper, we present a new algorithm and methodology to make use of both OTN switch and CD ROADM to avoid service contention without using CDC ROADM.

In this paper, we deal with the problem of relay selection in mobile edge computing networks, where a source node transmits a computation-intensive task to a destination via the aid of multiple relay nodes. It differs from the traditional relay nodes in the way that each relay node is equipped with an edge computing server, thus each relay node can execute the received task and forwards the computed result to the destination. Accordingly, we define a delay outage probability to evaluate the impact of the relay computing ability on the link communications, and then propose a latency-best relay selection (LBRS) scheme that not only consider the communication capability, but also consider the computing ability. The performance of the proposed relay selection scheme with the traditional communication-only relay selection (CORS) and computing-only selection (CPORS) schemes in terms of the delay outage probability and the diversity order is analyzed, compared with other relay selection schemes. We show that the proposed LBRS scheme reduces to the traditional CORS scheme under the high signal-to-noise ratio (SNR) region. We further reveal that the diversity orders of both the proposed LBRS and CORS schemes are dependent on the computing ability of relay nodes., Comment: submitted to IEEE SPAWC 2019

- Abstract
Blattisocius Keegan is a genus of predatory mites in the family Blattisociidae, with potential utility as biological control agents. In the present study, Illumina HiSeq was used to sequence the complete mt genome of B. keegani Fox. The mt genome of B. keegani was a circular DNA molecule of 17,314 bp. With a 1,935 bp-long non-coding region, it is the second largest mt genome in Acari. All 37 genes expected to be present in a standard metazoan mitogenome were identified in this genome. Phylogenetic analyses of 28 additional species of Acari were then performed based on the mt genome. Bayesian inference (BI) and Maximum likelihood (ML) algorithm were used to analyse the sequence data. Compared with Limulus polyphemus, rearrangements of 34 genes and changes of three genes orientation (trnE, trnF and trnS1) in B. keegani were observed. Additionally, the gene order of the six mesostigmata mites used in the study showed a lack of conserved gene blocks. BI and ML trees based on 13 protein-coding genes suggested that B. keegani was clustered with E. nicholsi and P. persimilis into a Phytoseioidea branch, which was consistent with the traditional classifications result.

We demonstrated a significant reduction of amplified spontaneous emission (ASE) threshold for an organic optical gain medium operation on an ITO-coated glass by introducing a solution-processed cellulose acetate (CA) thin film as a space layer between the ITO electrode and the optical gain active layer. Using PFO as an optical gain medium, we observed a 4.4-fold threshold reduction from 140 μJ/cm2 for glass/ITO/PFO device to 32 μJ/cm2 for glass/ITO/CA/PFO by controlling the thickness of CA film at 38 nm, and 9.9-fold reduction to 15 μJ/cm2 by further increasing the thickness of CA film to around 152 nm. Furthermore, we investigated symmetrical waveguide of glass/ITO/CA/PFO/CA configuration. It exhibited 3.3-fold lower ASE threshold than that of asymmetrical waveguide of glass/ITO/CA/PFO (6.0 versus 20.0 μJ/cm2), which was even lower than that of quartz/PFO (8.4 μJ/cm2). The CA film was also doped with Ag nanoparticles (AgNPs) in various ratios to improve the conductivity. ASE threshold of glass/ITO/CA(AgNPs)/PFO exhibited no detectable increase with the doping ratio of Ag nanoparticles up to 15 wt%.

PowerShell is so extremely powerful that we have seen that attackers are increasingly using PowerShell in their attack methods lately. In most cases, PowerShell malware arrives via spam email, using a combination of Microsoft Word documents to infect victims with its deadly payload. Nowadays, the de-obfuscation and analysis of PowerShell are still based on the manual analysis. However, as the number of malicious samples and obfuscation methods growing quickly, it is so slow that can’t satisfy the demand. In this paper, we propose a de-obfuscation method of PowerShell called PSDEM which has two layers de-obfuscation to get original PowerShell scripts. One is extracting PowerShell scripts from much obfuscated document code. The other is de-obfuscating scripts including encoding, strings manipulation and code logic obfuscation. Meanwhile, we design an automatic de-obfuscation and analysis tool for malicious PowerShell scripts in Word documents based on PSDEM. We test the performance of the tool from the accuracy of de-obfuscation and the efficiency of time, and evaluation results show that it has a satisfactory performance. PSDEM improves the efficiency and accuracy rate for analyzing malicious PowerShell Scripts in Word documents, as well as provides a path in which further analysis for security experts to get more information about attacks.

The new generation air-to-air missile is supposed to provide high manoeuvrability. For this demand, the high angle of attack to flight is needed. Aiming at the problem of strong cross-couplings caused by high angle of attack, it's difficult to satisfy the requirements of the robust stability and robust performance for the ordinary controller design of single channel. The paper takes advantage of multivariable design by Miu-Synthesis control. The method of transverse and lateral double channel design was adopted. And the Miu-Synthesis controller was computed. The effectiveness is validated by simulation comparison between the new method and the single channel classical control design method.

BACKGROUND: Circular RNA (circRNA) is a new type of noncoding RNA that can serve as ideal biomarkers. Evidence has showed that circRNAs play an important role in carcinogenesis and cancer development. However, little is known about the diagnostic value of circRNAs in papillary thyroid carcinoma (PTC) as well as their associations with clinicopathologic characteristics of patients with PTC. METHODS: The expression levels of hsa_circ_0137287 were detected in 120 PTC and 60 adjacent noncancerous thyroid tissues by quantitative real‐time polymerase chain reaction. The relationships between the expression of hsa_circ_0137287 in PTC and the clinicopathologic factors were analyzed. Finally, receiver operating characteristic (ROC) curves were generated to assess the diagnostic value of hsa_circ_0137287 as a biomarker for PTC. RESULTS: The expression of hsa_circ_0137287 was significantly downregulated in PTC tissues compared with adjacent noncancerous tissues (P

Field observation, geochemical signatures and zircon Hf isotope data indicate that Cuomuqu ophiolite in the Bangonghu area was formed in a back-arc basin (BAB) above a supra-subduction zone (SSZ). Zircon U-Pb dating of the diabase from the Cuomuqu massif yielded an age of 164.3±1.9 Ma, thus indicating that the ophiolite complex was formed in the Middle Jurassic during back-arc extension of the mature Bangonghu-Nujiang Ocean. The zircon eHf(t) and TDMC values of the plagiogranite are similar to the eHf(t) and TDM of the diabase, respectively. The mode of occurrence of plagiogranites and their bulk-rock and Hf isotope characteristics indicate that they were derived from the mantle, associated with the surrounding gabbro and diabase, and were formed by partial melting of altered and hydrated mafic rocks under shear conditions during lateral drifting of the oceanic crust. The zircon U-Pb age of the plagiogranite is 156.4±1.4 Ma, and it is 7.9 Ma younger than the hosting diabase. In this study, zircon chronological and Hf isotopic data were tentatively analyzed to determine the genesis of plagiogranites in the Cuomuqu ophiolite complex.

The Jiang Tso ophiolite, situated in the middle segment of the Bangong- Nujiang Suture Zone, is a part of the easternmost Qieli Lake ophiolite subzone and is close to the south of Pung Lake ophiolite. The rock association of Jiang Tso ophiolite is relatively complete and is mainly composed of metamorphic peridotite, gabbro and diabase. Comparing with N-MORB, the ophiolite is high in Mg and low in Ti, K, Na, P, and is depleted in Nb, Ta, Hf, Th and enriched in Rb, Sr and Ba. Geochemical characteristics of the Jiang Tso ophiolite indicate it is of a supra-subduction zone type formed in the spreading ridge of back arc basin. The SHRIMP U-Pb dating of zircons from the gabbro yielded a weighted average age of 188.1±4.1 Ma (MSWD=1.4), indicating the Jiang Tso ophiolite was formed in the late stage of early Jurassic. The Sr, Nd isotopic compositions show that the Tethyan mantle domain is the depleted mantle (DM), with enriched mantle domain II (EM II). They have the same Sr, Nd isotopic composition with the India Ocean MORB type.

The subduction of the Bangonghu-Nujiang Meso-Tethys and the collision between the Lhasa and Qiangtang blocks were important events in the growth of the Tibetan crust. However, the timing of collision initiation and closure timing, as well as nature and structure of the Bangonghu ocean basin, are still poorly constrained. The Lagkor Tso ophiolite, located in the south of Gerze County, Tibet, is one of the most completed ophiolites preserved in the southern side of the Bangonghu-Nujiang suture zone. This study discussed the tectonic evolution of the Bangonghu-Nujiang suture zone as revealed by the Lagkor Tso ophiolite investigated by field investigations, petrology, geochemistry, geochronology and tectonic analysis methods. We present new LA-ICP-MS zircon U-Pb and 39Ar/40Ar ages for the Lagkor Tso ophiolite, in addition to geochemical and platinum-group element (PGE) data presented for the Lagkor Tso ophiolite in Tibet. It is suggested that the ancient Lagkor Tso oceanic basin split in Middle Jurassic (161.2 ± 2.7 Ma – 165.4 ± 3.5 Ma), and experienced a second tectonic emplacement during the Early Cretaceous (137.90 ± 6.39 Ma). The Lagkor Tso ophiolite likely developed in an independent suture zone. The Bangonghu-Nujiang ocean subducted southwards, and the dehydration of the subducting oceanic crust materials caused partial melting of the continental mantle wedge, which formed the second-order expanding center of the obduction dish. This led to inter-arc expansion, followed by the formation of inter-arc and back-arc basins with island arc features, which are represented by ophiolites around the Shiquanhe-Lagkor Tso-Yongzhu region. The tectonic environment presently can be considered to be similar to that of the current Western Pacific, in which a large number of island arc-ocean basin systems are developed.

The boiler water circulating pump is the core component of the supercritical power station starting system. The circulating media in the pump is high temperature and high pressure water, so the reliability of the boiler water circulation pump is very important. Because the pressure fluctuation may cause resonance eccentric operation of the unit and even the destruction of the static and dynamic components, pressure fluctuation analysis of boiler circulating pump is helpful to improve the stability of unit operation. In this paper, the pressure fluctuation of impeller and guide vane in boiler water circulating pump was calculated and analyzed by software ANSYS-CFX. The results showed that: with the increase of the flow rate, the periodicity of pressure fluctuations at monitoring points in the impeller and the guide vane becomes more and more obvious, and the fluctuation amplitude decreases gradually. The pressure fluctuations of the monitoring points in the impeller are mainly affected by the leaf frequency of the guide vane which is 536.36Hz. The first three monitoring points in the guide vane are mainly affected by the leaf frequency of impeller which is 292.56Hz. There is no significant fluctuation at the monitoring point DY04.

The study aimed to establish effective nomograms for prediction of tumor regional recurrence and distant recurrence of papillary thyroid carcinoma (PTC) patients after partial or total thyroidectomy. These nomograms were based on a retrospective study on 1034 patients who underwent partial or total thyroidectomy for PTC. The predictive accuracy and discriminative ability of the nomograms were evaluated by the concordance index (C-index) and calibration curve. In addition, a validation cohort was included at the same institution. Multivariate analysis demonstrated that family history, maximal tumor diameter, capsular invasion, and lymph node staging were independent risk factors for regional recurrence-free survival; and family history, histological variants, capsular invasion, perineuronal invasion, and vascular invasion were independent risk factors for distant recurrence-free survival. They were selected into the 2 nomograms, respectively, and the C-index for regional recurrence-free survival and distant recurrence-free survival prediction were 0.72 and 0.83, respectively. In the validation cohort, the 2 nomograms displayed a C-index of 0.72 and 0.89, respectively. The nomograms developed in this study demonstrated their discrimination capability for predicting 3 and 5-year regional recurrence and distant recurrence after partial or total thyroidectomy, and can be used to identify high-risk patients.

Caching popular contents is a promising way to offload the mobile data traffic in wireless networks, but so far the potential advantage of caching in improving physical layer security (PLS) is rarely considered. In this paper, we contribute to the design and theoretical understanding of exploiting the caching ability of users to improve the PLS in a wireless heterogeneous network (HetNet). In such network, the base station (BS) ensures the secrecy of communication by utilizing some of the available power to transmit a pre-cached file, such that only the eavesdropper's channel is degraded. Accordingly, the node locations of BSs, users and eavesdroppers are first modeled as mutually independent poisson point processes (PPPs) and the corresponding file access protocol is developed. We then derive analytical expressions of two metrics, average secrecy rate and secrecy coverage probability, for the proposed system. Numerical results are provided to show the significant security advantages of the proposed network and to characterize the impact of network resource on the secrecy metrics., Comment: submitted to IEEE ICC 2018

In the control of palaeogeomorphology and fracture, multistage slope break zones are developed in Beixi Slope. After the analyses of the structural-paleogeomorphologic features, according to the relationships between slope break zones and subsags, we divide the slope break zones into three cells—inner slope break zones, middle slope break zones and outer slope break zones. Compared with the outer and middle slope break zones, the fault block traps are richly developed in the inner slope break zones, which is nearer to the oil generating depressions. And the conditions of reservoirs there are good. So they are excellent for hydrocarbon accumulation and preservation with good oil accumulating conditions.

The wedge shaped Dong Tso ophiolitic block is distributed near the transition point from the western to the middle sub–belt of the Bangong–Nujiang suture zone. The ophiolite is characterized by well–developed cumulate rocks that are mainly composed of cumulate and massive gabbros. In the cumulate gabbros, the adcumulate amphiboles are distributed extensively around the plagioclase and residual pyroxene grains; hence, the rocks are named adcumulate amphibole–gabbro. In this study, the formation age of the ophiolite has been estimated to be 166 ± 4 million years (Ma) by the sensitive high–resolution ion microprobe (SHRIMP) II U–Pb isotopic analysis of the zircons from the adcumulate amphibole–gabbro; the 40Ar/39Ar plateau age was estimated to be 148.19 ± 1.53 Ma, which should represent the emplacement time of the ophiolite, by isotopic dating of the pure amphibole mineral from the amphibole–schist. Two different suits of volcanic lavas have been recognized in this work. The purple colored pillow basalts have high TiO2 and P2O5 contents, and are rich in light rare earth elements (LREEs), large–ion lithospheric elements (LILEs) and high–field–strength elements (HFSEs), the characteristics that are the typical of the oceanic island basalt (OIB). On the other hand, other massive basaltic andesites of celadon color are poor in MgO; rich in Fe2O3, LREEs, LILEs, and HFSEs; and especially characterized by negative Nb and Ta anomalies, the properties that establish the andesites as continental arc volcanic rocks. It is concluded that hotspots had developed in the old Dong Tso basin, the oceanic basin that had been developing from middle Jurassic (166 Ma) or even before and emplaced northward in late Jurassic (about 148 Ma).

How to evaluate the influence of the architecture space combinations effected by the properties of construction materials on the evacuation efficiency is an open and important question to the digital architecture research community. Few research works have been done to investigate the influences. This paper proposed a space-time use efficiency index to evaluate the use efficiency of space and time resources in the evacuation of the public buildings. Then, this paper evaluated the influence of the architecture space combinations on the evacuation efficiency by using the three indicators, namely, the evacuation time, evacuation distance and the proposed space-time use efficiency. The evacuation efficiency performance of the seven popular architecture space combinations which could be constructed different materials were tested by an implemented experimental system prototype, and their advantages and disadvantages were compared to draw a meaning suggestion in the architecture design.
