Time-synchronised data streams from bio-loggers are becoming increasingly important for analysing and interpreting intricate animal behaviour including split-second decision making, group dynamics, and collective responses to environmental conditions. With the increased use of AI-based approaches for behaviour classification, time synchronisation between recording systems is becoming an essential challenge. Current solutions in bio-logging rely on manually removing time errors during post processing, which is complex and typically does not achieve sub-second timing accuracies. We first introduce an error model to quantify time errors, then optimise three wireless methods for automated onboard time (re)synchronisation on bio-loggers (GPS, WiFi, proximity messages). The methods can be combined as required and, when coupled with a state-of-the-art real time clock, facilitate accurate time annotations for all types of bio-logging data without need for post processing. We analyse time accuracy of our optimised methods in stationary tests and in a case study on 99 Egyptian fruit bats (Rousettus aegyptiacus). Based on the results, we offer recommendations for projects that require high time synchrony. During stationary tests, our low power synchronisation methods achieved median time accuracies of 2.72 / 0.43 ms (GPS / WiFi), compared to UTC time, and relative median time accuracies of 5 ms between tags (wireless proximity messages). In our case study with bats, we achieved a median relative time accuracy of 40 ms between tags throughout the entire 10-day duration of tag deployment. Using only one automated resynchronisation per day, permanent UTC time accuracies of ≤ 185 ms can be guaranteed in 95% of cases over a wide temperature range between 0 and 50 °C. Accurate timekeeping required a minimal battery capacity, operating in the nano- to microwatt range. Time measurements on bio-loggers, similar to other forms of sensor-derived data, are prone to errors and so far received little scientific attention. Our combinable methods offer a means to quantify time errors and autonomously correct them at the source (i.e., on bio-loggers). This approach facilitates sub-second comparisons of simultaneously recorded time series data across multiple individuals and off-animal devices such as cameras or weather stations. Through automated resynchronisations on bio-loggers, long-term sub-second accurate timestamps become feasible, even for life-time studies on animals. We contend that our methods have potential to greatly enhance the quality of ecological data, thereby improving scientific conclusions. [ABSTRACT FROM AUTHOR]

There is no validated method of assessing masseter muscle thickness (MMT) by ultrasound imaging (US). However, this is important to ensure study and measurement quality of MMT by US in future studies, as MMT differs depending on the examined area. Thus, this study's aim was to present a new standardized method for assessing the MMT by US and to evaluate the reliability, consistency, and accuracy of its measurements. We also compared the results of MMT measurements obtained by US and computer tomography (CT). The study included nine healthy adults. The US and CT scans were collected in a supine rest position with the mandible in relaxed position. US measurements were determined according to a new standardized protocol (with precise probe location). The MMT measured by CT and US over a seven-day interval showed excellent intra-rater reliability. The mean MMT measured by CT was 12.1 mm (1.74) on the right side and 11.9 mm (1.61) on the left side. The mean MMT measured by US was 12.7 mm (2.00) on the right side and 11.5 mm (1.37) on the left side. The mean percent error in MMT measurement between CT and US was below 6%. A strong linear relationship was found between the CT and US measurements of the MMT on both body sides (p < 0.001, r ≥ 0.93). The proposed method of MMT measurement using US demonstrated excellent reliability, yielding results similar to those obtained from CT images. We recommend the use of this standardization protocol in further studies where precise assessment of MMT by US is expected. [ABSTRACT FROM AUTHOR]

Ultrasound imaging (US) is being increasingly used to aid in the diagnosis of entrapment neuropathies. This study aims to evaluate the shear modulus and cross-sectional area (CSA) of the median nerve in patients with carpal tunnel syndrome (CTS). A total of 35 patients with CTS participated in the study. CSA and shear modulus testing were performed in shear wave elastography (SWE) mode in five positions of the right and left radiocarpal joints (intermediate position 0°, 45° of extension, maximum extension, 45° of flexion, and maximum flexion). There were significant side-to-side differences in the median nerve shear modulus at each wrist position as compared to the asymptomatic side. There were significant side-to-side differences in the median nerve CSA at each wrist position as compared to the asymptomatic side. Shear modulus increases in patients with CTS at different angular positions of flexion and extension of the radiocarpal joint. In individuals with CTS, the CSA of the median nerve is greater on the symptomatic side compared to the asymptomatic side. The CSA decreases in positions of maximum extension and 45° of flexion and in maximum flexion relative to the resting position. [ABSTRACT FROM AUTHOR]

Literature provides four basic theories to explain regional election results and how they differ from national patterns: authority of regional governments, ethnic or linguistic cleavages, congruence of national and regional electoral systems, and second-order election effects. The second-order national election theory explains why regional elections exhibit lower turnout levels, why government parties lose voter support, and why opposition, minor, and new parties gain support. While second-order election theory provides the dominant explanation for countries with low regional power, we argue in favour of an additional explanation based on incumbency effects on parties' electoral support. We test the explanations on Czech regional and national election data for the years 2000–2020. The results attest to a strong effect of regional governorship, with a bonus of 5 percentage points for parties whose governors run for re-election. Parties also receive another bonus when national-level MPs and local mayors are present on the ballot. [ABSTRACT FROM AUTHOR]

Hyperspectral imaging (HSI) is a new emerging modality useful for the noncontact assessment of free flap perfusion. This measurement technique relies on the optical properties within the tissue. Since the optical properties of hemoglobin (Hb) and melanin overlap, the results of the perfusion assessment and other tissue-specific parameters are likely to be distorted by the melanin, especially at higher melanin concentrations. Many spectroscopic devices have been shown to struggle with a melanin related bias, which results in a clinical need to improve non-invasive perfusion assessment, especially for a more pigmented population. This study investigated the influence of skin tones on tissue indices measurements using HSI. In addition, other factors that might affect HSI, such as age, body mass index (BMI), sex or smoking habits, were also considered. Therefore, a prospective feasibility study was conducted, including 101 volunteers from whom tissue indices measurements were performed on 16 different body sites. Skin tone classification was performed using the Fitzpatrick skin type classification questionnaire, and the individual typology angle (ITA) acquired from the RGB images was calculated simultaneously with the measurements. Tissue indices provided by the used HSI-device were correlated to the possible influencing factors. The results show that a dark skin tone and, therefore, higher levels of pigmentation influence the HSI-derived tissue indices. In addition, possible physiological factors influencing the HSI-measurements were found. In conclusion, the HSI-based tissue indices can be used for perfusion assessment for people with lighter skin tone levels but show limitations in people with darker skin tones. Furthermore, it could be used for a more individual perfusion assessment if different physiological influencing factors are respected. [ABSTRACT FROM AUTHOR]

In this study we, evaluated the effects of a 10-week sensorimotor exercise program on the thickness and side-to-side asymmetry of the lateral abdominal muscles in adolescent soccer players. From among 120 initially recruited participants, we included 90 athletes (aged 10–17 years old) in our final analysis. Healthy athletes who met our inclusion criteria were randomly divided into comparative experimental and control groups. Sensorimotor exercises were conducted twice weekly for 10-weeks in the experimental group, and the control group received no intervention. We took ultrasound measurements when participants were in supine and standing rest positions. In the supine position, the experimental group (a) reduced the asymmetry of the internal oblique (IO) muscle by 0.4 mm (MD: 0.7; 95% CI 0.6–1.1); (b) increased the thickness of the external oblique (EO) muscle on the right by 0.7 mm (MD: 0.2; 95% CI 0.1–0.6) and on the left by 0.9 mm (MD: 0.2, 95% CI 0.2–0.7); and (c) increased the muscle on the IO right by 0.8 mm (MD: 0.3; 95% CI 0.2–0.9) and on the, left by 1.2 mm (MD: 0.4 95% CI 0.3–1.1). In a standing position the experimental group increased the thickness of the EO on the right by 1.5 mm (MD: 0.6; 95% CI 0.03–1.2) and on the left by 2.1 mm (MD: 0.6; 95% CI 0.1–1.3) and increased the IO on the right by 1.2 mm (MD: 0.7; 95% CI 0.2–1.7) and on the left by 1.1 mm (MD: 0.9; 95%CI 0.1–2.0). Thus, this 10-week program of additional sensorimotor exercises reduced the (side-to-side) asymmetry of the internal oblique muscle and increased the thickness of the EO and IO muscles in young football players.

Over the past 25 years, substantial legal changes, research advances, and rapidly developing technology have resulted in dramatic changes in the postsecondary disability landscape. As a result, disability service professionals have seen their job duties significantly expand while serving a rapidly increasing and diversifying postsecondary population with disabilities. The current study details the relevant developments of the past 25 years, reviews literature documenting emerging challenges, and provides a case study of the system-wide approach developed by the University System of Georgia to support its disability service professionals during this period of rapid evolution. The services and supports provided by the three independent components (i.e., the Regents Centers for Learning Disorders, the Center for Inclusive Design and Innovation, and the Regents' Administrative Committee on Accessibility and Disability Services) are described. In addition, the authors describe how the components work in a collaborative way to leverage the benefits of a multidisciplinary approach. The authors close by describing how system-wide approaches or aspects of the University System of Georgia approach could be adopted in other states and settings. [ABSTRACT FROM AUTHOR]

We study the exclusive diffractive c c ¯ photoproduction in ultraperipheral pA collisions. The formalism makes use of off-diagonal generalizations of the unintegrated gluon distribution, the so-called generalized transverse momentum dependent distributions (GTMDs). We present two different formulations. The first one is based directly on gluon GTMD parametrizations in momentum space. Another option is the calculation of the GTMD as a Fourier transform of the dipole-nucleon scattering amplitude N(Y, r → ⊥, b → ⊥). The latter approach requires some extra regularization discussed in the paper. Different dipole amplitudes from the literature are used. Compared to previous calculations in the literature, we integrate over the full phase space and therefore cross sections for realistic conditions are obtained. We present distributions in rapidity of c or c ¯ , transverse momentum of the c c ¯ pair, four-momentum transfer squared as well as the azimuthal correlation between a sum and a difference of the c and c ¯ transverse momenta. The azimuthal correlations are partially due to the so-called elliptic gluon Wigner distribution. Different models lead to different modulations in the azimuthal angle. The modulations are generally smaller than 5%. They depend on the range of transverse momentum selected for the calculation. [ABSTRACT FROM AUTHOR]

A hydrogen concentration measurement device is developed for nuclear reactor primary circuits water. Despite the necessity to monitor hydrogen, only one producer offers a really selective hydrogen sensor on the world market because of the complexity of the device preparation when long‐term signal stability is required. Therefore, the Mass Transfer Laboratory at UCT Prague shares the experience gained during the sensor development. The results of the amperometric hydrogen sensor laboratory tests are presented, which demonstrate how to improve the sensor durability. An operational test in Dukovany nuclear power plant confirmed a significant improvement of the latest sensor version and showed that a simple principle could be realized in the form of a reliable device for industrial measurements.

This research concerns the possibility of using reclaimed asphalt pavement as a substitute for conventional aggregate in cement concrete mixtures for roads and airfield applications. The advantages of using reclaimed asphalt pavement as a replacement for natural aggregates are presented. Economic and environmental aspects are indicated, including the reduction in the consumption of natural non-renewable sources of mineral aggregates, as well as reduction in transport costs and emissions of harmful greenhouse gases. The consistency of this recycled material with the idea of sustainable development in the construction industry is emphasized. The test results of the used reclaimed asphalt and the assessment of the effect of its amount on the change in mechanical, physical and strength parameters of cement concrete are presented. It has been shown that the addition of reclaimed concrete reduces selected parameters of cement concrete, but it is possible to use it in structures with less traffic load, taking into account the sustainable development policy.

Purpose. Assessing the relationship between ultrasound imaging of respiratory muscles during tidal breathing and running tests (endurance and speed) in adolescent football players. Methods. Ultrasound parameters of the diaphragm and intercostal muscles (shear modulus, thickness, excursion, and velocity), speed (30-m distance), and endurance parameters (multi-stage 20-m shuttle run test) were measured in 22 male adolescent football players. The relation between ultrasound and running tests were analysed by Spearman's correlation. Results. Diaphragm shear modulus at the end of tidal inspiration was moderately negatively (R=-0:49Ip=0:2) correlated with the speed score at 10 m. The diaphragm and intercostal muscle shear modulus ratio was moderately to strongly negatively correlated with the speed score at 10 m and 30 m (about R = -0:48Ip = 0:03). Diaphragm excursion was positively correlated with the speed score at 5 m (R = 0:46Ip = 0:04) and 10 m (R = 0:52Ip = 0:02). Diaphragm velocity was moderately positively correlated with the speed score at 5 m (R=0:42Ip=0:06) and 30 m (RD 0:42Ip=0:07). Ultrasound parameters were not significantly related to all endurance parameters (R≤0:36Ip≥0:11). Conclusions. Ultrasound parameters of the respiratory muscles are related to speed score in adolescent football players. The current state of knowledge does not allow us to clearly define how important the respiratory muscles' ultrasound parameters can be in predicting some performance parameters in adolescent athletes.

The article's goal is to show how young adults assess the ties with their parents and the parental support they can count on in difficult situations. The following research questions were posed - what is the character of the ties with parents during young adulthood? Do parents provide strong support to their adult children? Are the ties with the mother and maternal support different from those one has with the father? The empirical material was collected as a part of the research project "Academic Youth on Family and Religion 2020." The survey was conducted in the spring of 2020 with CAWI (Computer Assisted (Aided) Web Interviews) among academic youth from numerous Polish academic centers (N = 621). Most young people assessed their ties with the parents and parental support positively, especially from the perspective of stability and satisfaction. But important differences were noticeable: the ties with the mother were evaluated more positively. The ties with the father were assessed as weaker, especially regarding expressions of affection, honest and open communication, and trust and care. Similarly, when assessing parental support, the mother turned out more involved and her support did not depend on other factors, such as her education and the respondents' economic situation.

Bio-telemetry from small tags attached to animals is one of the principal methods for studying the ecology and behaviour of wildlife. The field has constantly evolved over the last 80 years as technological improvement enabled a diversity of sensors to be integrated into the tags (e.g., GPS, accelerometers, etc.). However, retrieving data from tags on free-ranging animals remains a challenge since satellite and GSM networks are relatively expensive and or power hungry. Recently a new class of low-power communication networks have been developed and deployed worldwide to connect the internet of things (IoT). Here, we evaluated one of these, the Sigfox IoT network, for the potential as a real-time multi-sensor data retrieval and tag commanding system for studying fauna across a diversity of species and ecosystems. We tracked 312 individuals across 30 species (from 25 g bats to 3 t elephants) with seven different device concepts, resulting in more than 177,742 successful transmissions. We found a maximum line of sight communication distance of 280 km (on a flying cape vulture [Gyps coprotheres]), which sets a new documented record for animal-borne digital data transmission using terrestrial infrastructure. The average transmission success rate amounted to 68.3% (SD 22.1) on flying species and 54.1% (SD 27.4) on terrestrial species. In addition to GPS data, we also collected and transmitted data products from accelerometers, barometers, and thermometers. Further, we assessed the performance of Sigfox Atlas Native, a low-power method for positional estimates based on radio signal strengths and found a median accuracy of 12.89 km (MAD 5.17) on animals. We found that robust real-time communication (median message delay of 1.49 s), the extremely small size of the tags (starting at 1.28 g without GPS), and the low power demands (as low as 5.8 µAh per transmitted byte) unlock new possibilities for ecological data collection and global animal observation.

Parsonage–Turner syndrome (PTS) is a rare neurological disorder that causes major diagnostic problems. This paper presents a case report of a patient with PTS and proposes a new physiotherapy program. Case description: a 23-year-old man presents a sudden severe pain of his right arm. The man is consulted by several doctors and physiotherapists. Three magnetic resonance imagings (MRI), a nerve conduction study (NCS), and needle electromyography (EMG) are performed. After 6 months, based on medical history, physical examination and ultrasound imaging (UI), the physiotherapist suggests PTS, which is confirmed by a neurologist. Intervention: due to the lack of physiotherapy treatment standards in PTS, we apply neurodynamic techniques. Outcomes: neurodynamic techniques are effective in reducing pain and paraesthesia, improving sensation, and reducing nerve swelling (assessed by UI), as well as improving manual dexterity and overall health status. Conclusions: the patient with PTS is challenging for making an accurate diagnosis. This study shows an important role for UI, which shows changes in the musculocutaneous nerve, despite the lack of abnormalities in the MRI, NCS, and EMG, and helps in making an accurate diagnosis. This report also confirms that physiotherapy based on neurodynamic techniques may have beneficial effects in PTS. [ABSTRACT FROM AUTHOR]

The main aim of this study was to evaluate the effects of a 10-week sensomotor exercise programme on body balance and agility in a group of adolescent athletes. Initially, 120 adolescent football players were included in the study. In the final analysis, 90 athletes aged 10–17 years participated. The study was designed as a single-blinded, randomised controlled trial. Healthy athletes who met the inclusion criteria were randomly divided into two comparative groups: experimental and control groups. Sensomotor exercises were conducted twice weekly for 10 weeks in the experimental group. The adolescent footballers were subjected to the following tests: a COP (Centre of Pressure) test on a stabilometric platform, a Y balance test (Y-BT), and an agility test. The experimental group showed improvement with respect to the following variables: COP-based path length, with eyes open, for 30 s duration—improved by 5.3 cm (mean: 20.0; 95% CI 15.3–24.8); area, with eyes open, for 30 s duration—improved by 1 cm2 (mean 2.1; 95% CI 0.6–3.5); area, with eyes closed, for 30 s duration—improved by 0.4 cm2 (mean 2.2; 95% CI 1.6–2.8). The Y-BT was significantly improved in terms of the final score for the following variables: left leg anterior by 2.1% (mean 73.1; 95% CI 70.7–75.2); right leg posterolateral by 3.8% (mean 112.3; 95% CI 109.3–115.3); right and left leg posteromedial by 5.6% (mean 111.7; 95% CI 108.6–114.9) and 5.7% (mean 112.3; 95% CI 109.7–115.1), respectively; medium posterolateral by 3.2% (mean 111.8; 95% CI 109.0–114.7); medium posteromedial by 6.0% (mean 112.0; 95% CI 109.2–115.0); and Y total score by 3.5% (mean 98.8; 95% CI 96.6–100.9). The agility test in the experimental group was improved by 1.6 s (mean 13.2; 95% CI 12.6–14.0). A 10-week programme of additional sensomotor exercises improved selected parameters determining balance and agility in the young football players. [ABSTRACT FROM AUTHOR]

Temporomandibular joint ankylosis (TMJ ankylosis) manifests itself as a locked jaw and reduced mouth opening. We hypothesized that the efficacy of TMJ ankylosis surgery in a child may largely depend on physiotherapeutic management. In this case report, we present the treatment of a girl between 1 and 4 years of age, who was unable to open her jaws immediately after birth. Congenital ankylosis was diagnosed. Two models of therapeutic management were presented, with a surgical procedure to release bone fusion adopted as a starting point. In the first model, the rehabilitation procedure started 21 days after surgery. Despite rehabilitation, no clinical improvement was achieved (i.e. the child was still unable to open her jaws). In the second model, rehabilitation started from the day after surgery and management according to the second model allowed for obtaining therapeutic benefits. After therapy, the girl was able to abduct the mandible to a degree allowing for improved speech and the ability to crush food. This clinical case shows that the efficacy of surgical procedures may depend on the type of postoperative management. It was demonstrated that physiotherapy started immediately after the procedure to release the ankylosis improved the mandible mobility outcomes for this child. [ABSTRACT FROM AUTHOR]

Ultrasound imaging (US) is increasingly being used in the diagnosis of entrapment neuropathies. The aim of the current study was to evaluate changes in stiffness (shear modulus), cross-sectional area (CSA), and trace length (TRACE) of the ulnar nerve in patients with cubital tunnel syndrome (CuTS), with shear wave elastography (SWE). A total of 31 patients with CuTS were included. CSA, shear modulus, and TRACE examinations were performed in the SWE mode in four positions of the elbow: full extension, 45° flexion, 90° flexion, and maximum flexion. There were significant side-to-side differences in the ulnar nerve elasticity value at 45°, 90°, and maximal elbow flexion (all, p < 0.001) but not at elbow extension (p = 0.36). There were significant side-to-side differences in the ulnar nerve CSA value at each elbow position (all, p < 0.001). There were significant side-to-side differences in the ulnar nerve trace value at each elbow position (all, p < 0.001). The symptomatic ulnar nerve in patients with CuTS exhibited greater stiffness (shear modulus), CSA, and TRACE values, compared with the asymptomatic side. US examinations (shear modulus, CSA, and TRACE evaluation) of the ulnar nerve can be helpful in supporting and supplementing the diagnosis in patients with CuTS. [ABSTRACT FROM AUTHOR]

Static two-point discrimination (2PD) and Semmes–Weinstein monofilament (SWM) tests are commonly used to evaluate sensory disorders in the hand. The aim of this study was to evaluate the reliability of 2PD and SWM tests in the ulnar nerve innervation area in patients with cubital tunnel syndrome (CuTS) and healthy individuals. This was a two-group repeated-measures inter-rater and intra-rater reliability study. Twenty-one patients with CuTS and 30 healthy adults participated. The static 2PD test was performed using a standardized Dellon discriminator, whereas the SWM test was conducted using TOUCH TEST monofilaments. Two examiners performed both tests at the hypothenar eminence and the fourth and fifth digits (ulnar nerve innervation hand territory). First, examiner A conducted three series of 2PD and SWM tests twice with a 15-min rest period (within-day intra-rater reliability). Next, examiner B repeated the same examination 5 min after (inter-rater reliability). Examiner A conducted the same examination 7 days after (between-day intra-rater reliability). For single measurements, the inter-rater reliability and within-day intra-rater reliability in the 2PD was at least 0.81 in patients with CuTS or healthy subjects. The between-days intra-rater reliability for a single measurement varied from 0.56 to 0.95 in CuTS patients and healthy subjects. The between-days intra-rater reliability for mean value from three measurements was above 0.80. The kappa for SWM was above 0.8 and the percentage of agreement was at least 90% for all sessions and trials. In conclusion, the 2PD and SWM tests are reliable for assessing sensation in the ulnar nerve innervation area of the hand in patients with CuTS and healthy subjects. [ABSTRACT FROM AUTHOR]

A k $k$‐extended q $q$‐near Skolem sequence of order n $n$, denoted by Nnq(k) ${{\mathscr{N}}}_{n}^{q}(k)$, is a sequence s1,s2,...,s2n−1 ${s}_{1},{s}_{2},\ldots ,{s}_{2n-1}$ where sk=0 ${s}_{k}=0$ and for each integer ℓ∈[1,n]\{q} $\ell \in [1,n]\backslash \{q\}$ there are two indices i $i$, j $j$ such that si=sj=ℓ ${s}_{i}={s}_{j}=\ell $ and ∣i−j∣=ℓ $| i-j| =\ell $. For an Nnq(k) ${{\mathscr{N}}}_{n}^{q}(k)$ to exist it is necessary that q≡k(mod2) $q\equiv k\,(\mathrm{mod}\,2)$ when n≡0,1(mod4) $n\equiv 0,1\,(\mathrm{mod}\,4)$ and q≢k(mod2) $q\not\equiv k\,(\mathrm{mod}\,2)$ when n≡2,3(mod4) $n\equiv 2,3\,(\mathrm{mod}\,4)$, where (n,q,k)≠(3,2,3) $(n,q,k)\ne (3,2,3)$, (4,2,4) $(4,2,4)$. Any triple (n,q,k) $(n,q,k)$ satisfying these conditions is called admissible. In this manuscript, which is Part III of three manuscripts, we construct the remaining sequences; that is, Nnq(k) ${{\mathscr{N}}}_{n}^{q}(k)$ for all admissible (n,q,k) $(n,q,k)$ with q∈⌊n+23⌋,⌊n−22⌋ $q\in \left[\lfloor \frac{n+2}{3}\rfloor ,\lfloor \frac{n-2}{2}\rfloor \right]$ and k∈⌊2n3⌋,n−1 $k\in \left[\lfloor \frac{2n}{3}\rfloor ,n-1\right]$.

Introduction: The purpose of this study was to evaluate the potential utility of respiratory muscles ultrasound (US) imaging for assessing respiratory function and identify US variables that best correlate with pulmonary parameters. Materials and Methods: A search of 5 databases was conducted. Initially, there was no language, study design, or time frame restrictions. All studies assessing the relationship between pulmonary and US parameters were included. Two reviewers independently extracted and documented data regarding to examined population, age, gender, health condition, methodology, US, and pulmonary function measurements. All studies were qualitative synthesis. Results: A total of 1,272 participants from 31 studies were included. Diaphragm thickness, diaphragm thickening ratio, and diaphragm excursion amplitude were mainly used as US parameters. Forced vital capacity, forced expiratory volume1sec, and maximal inspiratory pressure were mainly used as pulmonary parameters. The relationships between pulmonary and US parameters varied from negligible to strong (depend on examined population and methodology used). Data were not quantitatively synthesis due to high heterogeneity in terms of study design, population examined, and various pulmonary and US parameters. Conclusion: A strong relationship between US measurements and pulmonary parameters was demonstrated in some studies but not others. This review confirmed that US measurements can complement spirometry, but the exact role of the US remains to be confirmed. Further studies using standardized methodology are needed to obtain more conclusive evidence on the usefulness of US for assessing respiratory function. [ABSTRACT FROM AUTHOR]

The aim of this study was to assess the intra-rater reliability and agreement of diaphragm and intercostal muscle elasticity and thickness during tidal breathing. The diaphragm and intercostal muscle parameters were measured using shear wave elastography in adolescent athletes. To calculate intra-rater reliability, intraclass correlation coefficient (ICC) and Bland–Altman statistics were used. The reliability/agreement for one-day both muscle measurements (regardless of probe orientation) were at least moderate. During the seven-day interval between measurements, the reliability of a single measurement depended on the measured parameter, transducer orientation, respiratory phase, and muscle. Excellent reliability was found for diaphragm shear modulus at the peak of tidal expiration in transverse probe position (ICC3.1 = 0.91–0.96; ICC3.2 = 0.95), and from poor to excellent reliability for the intercostal muscle thickness at the peak of tidal inspiration with the longitudinal probe position (ICC3.1 = 0.26–0.95; ICC3.2 = 0.15). The overall reliability/agreement of the analysed data was higher for the diaphragm measurements (than the intercostal muscles) regardless of the respiratory phase and probe position. It is difficult to identify a more appropriate probe position to examine these muscles. The shear modulus/thickness of the diaphragm and intercostal muscles demonstrated good reliability/agreement so this appears to be a promising technique for their examination in athletes.

Background: The Functional Movement Screen (FMS) and the Y Balance Test (Y-BT) are screening tools to detect movement deficits and to identify footballers at high risk of injury. If these tools are able to identify athletes with high risk of injury, they should measure the same construct and also be highly correlated. Objectives: The aim of the study was to determine the relationship between the FMS and Y-BT in youth footballers. The present study also aimed to assess the degree of association between the FMS and Y-BT considering high-injury-risk (FMS <= 14 points and Y-BT <= 89.6%) and low-injury-risk groups (FMS > 14 points and Y-BT > 89.6%). Method: A sample of 226 healthy athletes (mean age: 14.0 ± 2.3 years) was selected from a football club. The FMS and Y-BT data were collected from all participants. The Y-BT raw data were normalised to the relative length of the lower limbs. Spearman's correlation was used in the analysis. Results: For the whole group, there was a moderate correlation (R = 0.41; p < 0.001) between the composite FMS score and composite Y-BT score. The strength of relationships varied from weak to moderate between the FMS subtests and most Y-BT results for each direction. In the high-injury-risk group, there was no correlation (R = 0.11; p = 0.61) between the composite FMS score and composite Y-BT score. For the low-injury-risk group, there was a weak significant correlation (R = 0.27; p < 0.007) between the composite FMS score and composite Y-BT score. Additionally, 56 and 53 athletes were classified to the high-injury-risk group based on the FMS and Y-BT, respectively. Only 23 athletes were classified to the high-risk group by both tests. Conclusions: Youth footballers showed only weak to moderate correlations between the FMS and the Y-BT. Footballers classified in the high-injury-risk group based on the FMS and Y-BT presented a different relationship between the FMS and Y-BT tasks compared to the low-injury-risk group. The results confirmed that the FMS and Y-BT should not be used interchangeably as they assess different movement deficits in the group of youth football players. The study results may partially suggest that using one of these screening tools cannot successfully predict injury risk in adolescent football players. This justifies the need to use these tests simultaneously to identify possible neuromuscular control deficits in youth footballers. [ABSTRACT FROM AUTHOR]

Background: To date, various forms of physiotherapy are used in the treatment of cubital tunnel syndrome (CuTS). The effectiveness of physiotherapy for CuTS is inconclusive. The aim of this systematic review was to evaluate the effects of physiotherapy in the conservative treatment of CuTS. Methods: The six databases were searched from December 2020 to March 2022. The inclusion criteria were randomised controlled trials, case series, and case reports that evaluate the effects of physiotherapy in the treatment of adult participants with diagnosis CuTS. A total of 11 studies met the eligibility criteria, capturing a total of 187 participants. Results: In three types of papers, pain, muscle strength, and limitation of upper limb function were the most frequently assessed characteristics. Physiotherapy was most often based on manual therapy, neurodynamic techniques, and electrical modalities. One clinical trial rated the risk of bias "high" and the other two "some concerns". In case-series designs, five studies rated the risk of bias as "serious" and three as "moderate". Most of the studies showed a significant improvement in the clinical condition, also in the follow-up study. Only one clinical trial showed no therapeutic effect. Conclusion: There is no possibility of recommending the best method of physiotherapy in clinical practice for people with CuTS based on the results of this systematic review. More high-quality studies are required. [ABSTRACT FROM AUTHOR]

Concrete airfield pavements can frequently suffer from initially small and relatively shallow delamination of the subsurface concrete layer. It may be due to natural and forced temperature impact on the pavement. As a result of these impacts, thermal stresses and other phenomena are formed in the concrete slab. The significant phenomena are those related to the movement of water vapour in the slab cross-section and the associated processes leading to defects of the concrete structure. They are due to the complex interaction of various phenomena: thermal, humidity and strength that were considered damage stimulants. [ABSTRACT FROM AUTHOR]

The impact of aircraft on airport pavements is varied and closely related to their operational durability. The article presents the impact of the annealing process related to the forced impact of airplanes on airport pavements. The composition of cement concrete with ceramic dust, which is characterized by increased thermal resistance, has been proposed. Two research cycles were programmed, differentiated by the annealing scheme and the way in which the temperature influences the annealing time. Samples stored at a temperature of 20 ± 2 °C were subjected to testing. The tests were carried out for two diagrams: A and B. The first—diagram A—included the continuous impact of the flue gas stream on the samples for a period of 350 min with a test step every 25 min. For the second—diagram B—the samples were alternately heated (1 min) and cooled (15 min). The influence of the proposed pavement mix on changes in the internal structure of cement concrete and the increase in its resistance to high temperatures was determined. In the microstructure of the CC-1 concrete matrix, it was found that there were plate-granular portlandite crystals up to 10 µm in size and ettringite crystals with a length of 8 µm. In the CC-2 concrete, the ettringite crystals were less numerous and had a length of up to 5 µm, there were also continuous contact zones between the aggregate grains and the cement matrix (diagrams A). The alternating annealing/cooling (diagram B) resulted in the ettringite crystals in the CC-1 matrix being up to 10 µm long, and in the CC-2 concrete up to 7 µm long. The contact zone between the aggregate grain and the matrix in CC-2 concrete was continuous, and the microcracks in CC-1 concrete were up to 8 nm. Regardless of the heating diagram, in the surface zone, there were larger microcracks in the CC-1 concrete than in the CC-2 concrete. For diagram A they were 14 µm and 4 µm and for diagram B they were 35 µm and 5 µm, respectively. It was found that concrete with ceramic dust is characterized by a lower and more stable temperature increase. In scheme A, the average temperature increase on the heated surface ranged from 46 °C to 79.5 °C for CC-1 concrete, and from 33.3 °C to 61.3 °C for CC-2 concrete. However, in scheme B, the temperature after 350 heating cycles for CC-1 concrete increased to 129.8 °C, and for CC-2 concrete to 116.6 °C. After the cooling period, the temperature of CC-1 and CC-2 concrete was comparable and amounted to 76.4 C and 76.3 °C, respectively. CC-2 concrete heats to lower values, and favorable changes in internal structure translate into higher strength and durability (after 350 heating cycles according to scheme A, the strength of CC-1 concrete was 67.1 MPa and of CC-2 concrete 83.9 MPa, while in scheme B, respectively, 55.4 MPa for CC-1 and 75 MPa for CC-2).

To date, no studies have assessed lateral abdominal muscles' (LAM) elasticity and thickness in relation to hip and groin symptoms in any population. The objectives were to a) assess the relationship between LAM ultrasound measurements (elasticity and thickness) and self-reported subscales of the Copenhagen Hip and Groin Outcome Score (HAGOS) and b) compare LAM elasticity and thickness between asymptomatic and symptomatic sides. Shear modulus and thickness of the oblique external (OE), internal (OI) and transversus abdominis (TrA) muscles in 25 young soccer players were assessed at rest and during isometric contraction using ultrasound shear wave elastography. HAGOS subscales were used to assess self-reported hip/groin problems. There was a significant (p < 0.05) moderate correlation between allometric-scaled OI resting thickness (mean of right and left) and the Activities of Daily Living (r = 0.40), Sport (r = 0.57) and Quality of Life (QOL) (r = 0.41) HAGOS subscales. Also, a moderate significant correlation was found between allometric-scaled TrA resting thickness and the QOL subscale (r = 0.47). Moderate correlations were found between resting OI shear modulus and the QOL (r = 0.44), between right TrA shear modulus during contraction and Symptoms (r = 0.57), and between the left TrA shear modulus during contraction and Physical Activity (r = 0.41) subscales. No differences were found between the symptomatic and asymptomatic side in thickness and elasticity measurements among soccer players with unilateral symptoms (p > 0.05). The relationships found between LAM and hip/groin problems in youth male soccer players indicate that muscles are thinner and more elastic (less stiff) in more symptomatic athletes.

Background: Many birds species range over vast geographic regions and migrate seasonally between their breeding and overwintering sites. Deciding when to depart for migration is one of the most consequential life-history decisions an individual may make. However, it is still not fully understood which environmental cues are used to time the onset of migration and to what extent their relative importance differs across a range of migratory strategies. We focus on departure decisions of a songbird, the Eurasian blackbird Turdus merula, in which selected Russian and Polish populations are full migrants which travel relatively long-distances, whereas Finnish and German populations exhibit partial migration with shorter migration distances. Methods: We used telemetry data from the four populations (610 individuals) to determine which environmental cues individuals from each population use to initiate their autumn migration. Results: When departing, individuals in all populations selected nights with high atmospheric pressure and minimal cloud cover. Fully migratory populations departed earlier in autumn, at longer day length, at higher ambient temperatures, and during nights with higher relative atmospheric pressure and more supportive winds than partial migrants; however, they did not depart in higher synchrony. Thus, while all studied populations used the same environmental cues, they used population-specific and locally tuned thresholds to determine the day of departure. Conclusions: Our data support the idea that migratory timing is controlled by general, species-wide mechanisms, but fine-tuned thresholds in response to local conditions. [ABSTRACT FROM AUTHOR]

A k‐extended q‐near Skolem sequence of order n, denoted by Nnq(k), is a sequence s1,s2,...,s2n−1 where sk=0 and for each integer ℓ∈[1,n]\{q} there are two indices i,j such that si=sj=ℓ and ∣i−j∣=ℓ. For a Nnq(k) to exist it is necessary that q≡k(mod2) when n≡0,1(mod4) and q≢k(mod2) when n≡2,3(mod4), where (n,q,k)≠(3,2,3),(4,2,4). Any triple (n,q,k) satisfying these conditions is called admissible. In this article, which is Part II of three articles, we construct sequences Nnq(k) for all admissible (n,q,k) with q∈[⌊n2⌋,n].

The Hip and Lower Limb Movement Screen (HLLMS) was developed to detect altered movement patterns and asymmetry specifically related to hip, pelvic, and lower limb movement control, as the other tools, such as the Functional Movement Screen (FMS), lacked focus on the hip and pelvic area. Both screening tools contain symmetrical and asymmetrical motor tasks which are based on observation of different aspects of each task performance. One motor task is in both screening tools. Therefore, they have some common features. The present study aimed to assess the relationship between the HLLMS and FMS performance in youth football players. The study included 41 elite male football (soccer) players (age: 15.6 ± 0.50 years), and the HLLMS and FMS scores were analyzed by assessing Spearman's rank correlation. The FMS total score and the FMSMOVE were moderately correlated with the HLLMS total score (R = −0.54; −0.53, respectively). The FMS rotatory stability task was moderately correlated with the HLLMS small knee bend with the trunk rotation task (R = −0.50). The FMS deep squat task was moderately correlated with the HLLMS deep squat task (R = −0.46). The FMS hurdle step was weakly correlated with two of the HLLMS tasks: standing hip flexion (R = −0.37) and hip abduction with external rotation (R = −0.34). There were no other relationships found (p > 0.05). Out of the seven FMS tasks, only one asymmetrical (trunk rotary stability) and one symmetrical (deep squat) task were moderately related to the newly developed HLLMS tool contributing moderate relationship between the FMS total score and the HLLMS total score. Other FMS tasks were weakly or unrelated with the HLLMS. These findings indicate that these two screening tools mainly assess different aspects of movement quality in healthy youth football players.

Objective The purpose of this study was to evaluate the effects of physical therapy on pulmonary function and respiratory muscle strength in children with cerebral palsy (CP). Methods A search of 10 databases was conducted for this systematic review. Initially, there were no language, study design, or time frame restrictions. All studies assessing the effect of physical therapy on the respiratory system in children with CP were included. Two reviewers independently extracted and documented data. The data extracted included description of the intervention (duration, therapeutic method) and study results (change of spirometric parameters, respiratory muscle strength). The effects of physical therapist treatment were calculated using software. Results A total of 269 children aged 5 to 18 years from 10 studies were included. The included studies consisted of 5 different therapeutic methods (inspiratory muscle training [IMT], aerobic training, swimming, respiratory exercise, exercise with elastic bands). Physical therapist intervention led to a significant increase in the maximal expiratory pressure (MEP) (I2 = 0%), peak expiratory flow (I2 = 0%), and maximum oxygen consumption (I2 = 37%). A separate analysis of the most frequently used therapy (IMT) showed a positive effect on MEP (I2 = 0%) and maximal inspiratory pressure (I2 = 35%). Conclusion Various forms of physical therapy have potential to demonstrate a positive effect on maximal inspiratory pressure, MEP, and peak expiratory flow in children with CP. There is no possibility to recommend the best method and duration of the physical therapy; however, it can be suggested that physical therapy should be applied for at least 4 weeks and include IMT. Impact CP is one of the most common causes of physical disabilities in children, and pulmonary dysfunction is the leading cause of death in people with CP. Thus, it is warranted to seek different approaches that may improve pulmonary function in people with CP. This review has shown that various forms of physical therapy have potential to improve the pulmonary function of children with CP. [ABSTRACT FROM AUTHOR]

In a seasonal world, organisms are continuously adjusting physiological processes relative to local environmental conditions. Owing to their limited heat and fat storage capacities, small animals, such as songbirds, must rapidly modulate their metabolism in response to weather extremes and changing seasons to ensure survival. As a consequence of previous technical limitations, most of our existing knowledge about how animals respond to changing environmental conditions comes from laboratory studies or field studies over short temporal scales. Here, we expanded beyond previous studies by outfitting 71 free-ranging Eurasian blackbirds (Turdus merula) with novel heart rate and body temperature loggers coupled with radio transmitters, and followed individuals in the wild from autumn to spring. Across seasons, blackbirds thermoconformed at night, i.e. their body temperature decreased with decreasing ambient temperature, but not so during daytime. By contrast, during all seasons blackbirds increased their heart rate when ambient temperatures became colder. However, the temperature setpoint at which heart rate was increased differed between seasons and between day and night. In our study, blackbirds showed an overall seasonal reduction in mean heart rate of 108 beats min-1 (21%) as well as a 1.2°C decrease in nighttime body temperature. Episodes of hypometabolism during cold periods likely allow the birds to save energy and, thus, help offset the increased energetic costs during the winter when also confronted with lower resource availability. Our data highlight that, similar to larger non-hibernating mammals and birds, small passerine birds such as Eurasian blackbirds not only adjust their heart rate and body temperature on daily timescales, but also exhibit pronounced seasonal changes in both that are modulated by local environmental conditions such as temperature.

Objectives: The aim of this study is to evaluate 2-point discrimination sense (2PD), strength and kinesthetic differentiation of strength (KDS), range of motion (ROM) and kinesthetic differentiation of movement (KDM) dysfunctions in occupationally active women with mild and moderate forms of carpal tunnel syndrome (CTS) compared to a healthy group.Material and Methods: The 2PD sense, muscle strength and KDS, as well as the ROM and KDM of the radiocarpal articulation were assessed.Results: The results of the 2PD sense assessment showed significantly higher values in all the examined fingers in the CTS women group compared to healthy women (p < 0.01). There was a significant difference in the percentage value of error in the strength and KDS of pincer and cylindrical grips (p < 0.01) in the CTS women group compared to healthy women. There was no difference in the ROM of flexion and extension between studied groups (p > 0.05). There was a significant difference in the percentage value of error in the KDM of flexion and extension movement of the radiocarpal articulation (p < 0.01) between the studied groups.Conclusions: There are significant differences in the 2PD sense, KDS and KDM in occupationally active women with mild and moderate forms of CTS compared to healthy women. There are no significant differences in ROM in professionally active women with mild and moderate forms of CTS compared to healthy women. Int J Occup Med Environ Health. 2019;32(2):185-96.

Considering that knowledge about lateral abdominal muscles (LAM) in idiopathic scoliosis (IS) is still very limited, the aims of this study were: (a) to compare LAM thickness and elasticity between C-shaped IS and non-scoliotic population; and (b) to compare LAM thickness and elasticity between C-shaped thoracic, thoracolumbar, and lumbar IS. A total of 259 adolescents were included in the final analysis; among these, 108 were IS and 151 were non-IS. LAM thickness and elasticity were measured at rest and during isometric contraction by an Aixplorer ultrasound scanner. Out of all LAM, only OE thickness was higher on the convex body side compared to the concave side in lumbar and thoracolumbar scoliosis. It may be related with muscle's atrophy/hypertrophy or other tissues displacement rather than different force generated by the muscle on both body sides, because an asymmetry in the elasticity of the LAM between the convex and concave side was not presented. The only TrA was stiffer in lumbar scoliosis compared to thoracolumbar and thoracic scoliosis. LAM elasticity was similar in IS and non-IS adolescents. [ABSTRACT FROM AUTHOR]
