Abstract
Background
In psychological services, the transition to the disclosure of ideation about self-harm and suicide (ISS) is a critical point warranting attention. This study developed and tested a succinct descriptor to predict such transitions in an online synchronous text-based counseling service.

Method
We analyzed two years’ worth of counseling sessions (N = 49,770) from Open Up, a 24/7 service in Hong Kong. Sessions from Year 1 (N = 20,618) were used to construct a word affinity network (WAN), which depicts the semantic relationships between words. Sessions from Year 2 (N = 29,152), including 1168 with explicit ISS, were used to train and test the downstream ISS prediction model. We divided and classified these sessions into ISS blocks (ISSBs), blocks prior to ISSBs (PISSBs), and non-ISS blocks (NISSBs). To detect PISSB, we adopted complex network approaches to examine the distance among different types of blocks in WAN.

Results
Our analyses find that words within a block tend to form a module in WAN and that network-based distance between modules is a reliable indicator of PISSB. The proposed model yields a c-statistic of 0.79 in identifying PISSB.

Conclusions
This simple yet robust network-based model could accurately predict the transition point of suicidal ideation prior to its explicit disclosure. It can potentially improve the preparedness and efficiency of help-providers in text-based counseling services for mitigating self-harm and suicide.
Preregistration: Practical Considerations for Speech, Language, and Hearing Research
Authors: Brown Violet A. , Strand Julia F. 
Published: December 2022

Purpose:
In the last decade, psychology and other sciences have implemented numerous reforms to improve the robustness of our research, many of which are based on increasing transparency throughout the research process. Among these reforms is the practice of preregistration, in which researchers create a time-stamped and uneditable document before data collection that describes the methods of the study, how the data will be analyzed, the sample size, and many other decisions. The current article highlights the benefits of preregistration with a focus on the specific issues that speech, language, and hearing researchers are likely to encounter, and additionally provides a tutorial for writing preregistrations.

Conclusions:
Although rates of preregistration have increased dramatically in recent years, the practice is still relatively uncommon in research on speech, language, and hearing. Low rates of adoption may be driven by a lack of understanding of the benefits of preregistration (either generally or for our discipline in particular) or uncertainty about how to proceed if it becomes necessary to deviate from the preregistered plan. Alternatively, researchers may see the benefits of preregistration but not know where to start, and gathering this information from a wide variety of sources is arduous and time consuming. This tutorial addresses each of these potential roadblocks to preregistration and equips readers with tools to facilitate writing preregistrations for research on speech, language, and hearing.

Published: December 2022

Context. Young massive clusters provide the opportunity to study the outcome of the star formation process and the early evolution of star clusters. In the first few million years, the (massive) stars dynamically interact, producing runaways and affecting the initial (binary) population.
Aims. Observing and interpreting the dynamics of young massive clusters is key to our understanding of the star formation process and predicting the outcome of stellar evolution, for example the number of gravitational wave sources.
Methods. We have studied NGC 6611 in the Eagle Nebula (M16), a young massive cluster hosting ∼19 O stars. We used Gaia EDR3 data to determine the membership, age, cluster dynamics, and the kinematics of the massive stars including runaways.
Results. The membership analysis yields 137 members located at a mean distance of 1706 ± 7 pc. The colour – absolute magnitude diagram reveals a blue and a red population of pre-main-sequence stars, consistent with two distinct populations of stars. In line with earlier studies, the youngest (reddest) population has a mean extinction of AV = 3.6 ± 0.1 mag and an age of 1.3 ± 0.2 Myr, while the older population of stars has a mean extinction of AV = 2.0 ± 0.1 mag and an age of 7.5 ± 0.4 Myr. The latter population is more spatially extended than the younger generation of stars. We argue that most of the OB stars belong to the younger population. We identify eight runaways originating from the centre of NGC 6611, consistent with the dynamical ejection scenario.
Conclusions. We have studied the kinematics of the O stars in detail and show that ≳50% of the O stars have velocities comparable to or greater than the escape velocity. These O stars can be traced back to the centre of NGC 6611 with kinematic ages ranging from 0 to 2 Myr. These results suggest that dynamical interactions played an important role in the early evolution of NGC 6611, which is surprising considering the relatively low current stellar density (0.1–1 × 103 M⊙ pc−3). Comparing our results to simulations of young massive clusters, the initial radius of 0.1–0.5 pc (needed to produce the observed O star runaway fraction) is not consistent with that of NGC 6611. We propose a scenario where the O stars initially form in wide binaries or higher order systems and possibly harden through dynamical interactions.
Ultra-broadband and tunable infrared absorber based on VO2 hybrid multi-layer nanostructure

Published: December 2022

We propose an ultra-broadband near- to mid-infrared (NMIR) tunable absorber based on VO2 hybrid multi-layer nanostructure by hybrid integration of the upper and the lower parts. The upper part is composed of VO2 nanocylinder arrays prepared on the front illuminated surface of quartz substrate, and VO2 square films and VO2/SiO2/VO2 square nanopillar arrays prepared on the back surface. The lower part is an array of SiO2/Ti/VO2 nanopillars on Ti substrate. The effects of different structural parameters and temperature on the absorption spectra were analyzed by the finite-difference time-domain method. An average absorption rate of up to 94.7% and an ultra-wide bandwidth of 6.5 μm were achieved in NMIR 1.5–8 μm. Neither vertical incident light with different polarization angles nor large inclination incident light has a significant effect on the absorption performance of the absorber. The ultra-broadband high absorption performance of this absorber will be widely used in NMIR photodetectors and other new optoelectronic devices.

Published: December 2022

Zusammenfassung
Hintergrund Im Rahmen der COVID-19-Pandemie hat die Online-Videosprechstunde einen zunehmenden Stellenwert in der Orthopädie und Unfallchirurgie erhalten. In der Literatur werden verschiedene Adaptationsmöglichkeiten für digitale orthopädisch-unfallchirurgische klassische Gelenk- und Funktionsuntersuchungen für eine Online-Videosprechstunde beschrieben.
Methodik Es wurde eine systematische Literaturrecherche der wissenschaftlichen Publikationen für passive digitale Gelenk- und Funktionsuntersuchungen auf der Datenbank PubMed (Zeitraum: Januar 2010 bis April 2021) durchgeführt. Die identifizierten Untersuchungstechniken wurden anschließend systematisch nach Körperregion und Pathologie zusammengefasst, detailliert beschrieben und mit reproduzierten Fotografien nachgestellt.
Ergebnisse Es konnten 17 Artikel eingeschlossen werden. Die beschriebenen Untersuchungstechniken waren überwiegend an die klassischen orthopädischen Tests angelehnt und so adaptiert, dass sie selbstständig durch den Patienten durchgeführt werden können. Als Hilfsmittel wurden alltägliche Gegenstände beschrieben. In 5 Publikationen wurde die Durchführung der Online-Videosprechstunde mit klassischen orthopädischen Untersuchungen verglichen. Die Funktionsuntersuchungen in der Online-Videosprechstunde zeigte im Vergleich zur Inspektion und ROM-Testung eine schlechtere Übereinstimmung mit der klassischen orthopädischen Untersuchung.
Zusammenfassung In der Literatur existiert eine breite Grundlage an bereits publizierten Untersuchungstechniken für die orthopädisch-unfallchirurgische Videosprechstunde. Die beschriebenen Untersuchungen orientieren sich weitgehend an den klassischen orthopädisch-unfallchirurgischen Tests. Die vorgestellten Untersuchungsmöglichkeiten müssen in Zukunft auf ihre Evidenz geprüft, validiert und ggf. weiter angepasst werden.
Berufliche Belastung als möglicher Risikofaktor für einen Rotatorenmanschettenschaden - Systematisches Review und Meta-Analyse
Authors: Diener Greta-Linn , Spahn Gunter , Hofmann Gunther O 
Published: December 2022

Zusammenfassung
Zielstellung Im September 2021 wurde vom „Ärztlichen Sachverständigenbeirat Berufskrankheiten“ beim Bundesministerium für Arbeit und Soziales (BMAS) die Empfehlung ausgesprochen, Läsionen der Rotatorenmanschette durch berufliche und langjährige Überschulterarbeit, repetitive Bewegungen, Tragen und Heben von schweren Lasten und Hand-Arm-Schwingungen (Vibration) als Berufskrankheit anzuerkennen. Um ein genaueres Verständnis über den Zusammenhang zwischen beruflichen Risikofaktoren und Schäden der Rotatorenmanschette zu erlangen, wurde in einer systematischen Literaturrecherche deren Einfluss auf die Entstehung von Schäden an der Rotatorenmanschette der Schulter untersucht und anhand dieser Ergebnisse die Empfehlung des BMAS eingeordnet.
Material und Methode Mithilfe einer systematischen Literaturrecherche wurde in den Datenbanken PubMed, Cochrane und Web-of-Science nach Arbeiten gesucht, die sich mit beruflicher Schulterbelastung und damit einhergehenden Schulterbeschwerden beschäftigten. Als Risikofaktoren wurde der Einfluss von Überkopfarbeit, repetitiver Arbeit, Vibration und Tragen und Heben von schweren Lasten untersucht.
Ergebnisse 58 Studien wurden im Volltext gelesen, wovon 13 Studien in die Metaanalyse inkludiert wurden. Alle untersuchten Risikofaktoren zeigten einen signifikanten Zusammenhang auf, wobei die stärkste Dosis-Wirkungs-Beziehung für die Risikofaktoren „Überkopfarbeit“ und „repetitive Arbeit“ gefunden wurde: Einfluss von Überkopfarbeit: 2,23 (95%-KI 1,98–2,52), Einfluss von repetitiver Arbeit: 2,17 (95%-KI 1,92–2,46), Einfluss von Vibration: 1,59 (95%-KI 1,13–2,23), Heben und Tragen von schweren Lasten: 1,57 (95%-KI 1,15–2,15).
Schlussfolgerung Zwar konnte in unserer Studie für alle 4 untersuchten Risikofaktoren ein signifikanter Effekt nachgewiesen werden, jedoch ist aufgrund der unzureichenden Menge an verfügbaren Studien mit qualitativ hochwertigem Studiendesign und unzureichender pathophysiologischer Erklärung für die Entstehung eines Rotatorenmanschettenschadens bei diesen mechanischen Tätigkeiten nach derzeitigem Stand ein Zusammenhang nicht sicher nachweisbar.

Electrochemical Benzylic C(sp3)–H Amidation via Ritter-Type Reaction in the Absence of External Mediator and Oxidant
Authors: Liu Ping , Sun Peipei , Chu Qiao , Zhou Yeqin , Ji Ce 
Published: December 2022

AbstractA straightforward method involving electrochemical Ritter-type amidation of alkylarenes in the absence of external mediator and oxidant is described. This direct benzylic C(sp3)–H amidation utilizes cheap CH3CN or other nitriles as the nitrogen source and trace amount of H2O in the solvent as the oxygen and hydrogen source. A wide range of alkylarenes were found to be compatible, providing a variety of N-benzyl-substituted amides in moderate to good yields.
Prediction of Marathon Performance using Artificial
Intelligence
Authors: Lerebourg Lucie , Saboul Damien , Clémençon Michel , Coquart Jérémy Bernard 
Published: December 2022

AbstractAlthough studies used machine learning algorithms to predict performances in
sports activities, none, to the best of our knowledge, have used and validated
two artificial intelligence techniques: artificial neural network (ANN) and
k-nearest neighbor (KNN) in the running discipline of marathon and compared the
accuracy or precision of the predicted performances. Official French rankings
for the 10-km road and marathon events in 2019 were scrutinized over a dataset
of 820 athletes (aged 21, having run 10 km and a marathon in the same
year that was run slower, etc.). For the KNN and ANN the same inputs (10-km race
time, body mass index, age and sex) were used to solve a linear regression
problem to estimate the marathon race time. No difference was found between the
actual and predicted marathon performances for either method
(p>0,05). All predicted performances were significantly
correlated with the actual ones, with very high correlation coefficients
(r>0,90; p<0,001). KNN outperformed ANN with a
mean absolute error of 2,4 vs 5,6%. The study confirms the validity of
both algorithms, with better accuracy for KNN in predicting marathon
performance. Consequently, the predictions from these artificial intelligence
methods may be used in training programs and competitions.

Published: December 2022

AbstractThe response of female cyclists depending on the functional test duration has not
been studied. This study aims to analyse the effect of modification of the
duration of two different functional tests: Wingate (WAnT) and Functional Power
Threshold (FTP) in female cyclists. Fourteen cyclists (27±8 years,
1,66±0,08 m, and 60,6±7,2 kg) performed 2 test
days with a 24-hour break between days, varying the test duration (WAnT 20- or
30-sec, and FTP 8- or 10-min). Relative power output, cadence, heart rate, local
oxygen saturation, lactate, and rating of perceived exertion were measured in
each test. Time duration did not affect the power output outcomes in both tests
(p>0,05). However, WAnT of 20 sec, compared with the test of
30 sec, resulted in a lower cadence decrease in the last 5 sec
(p<0,01, ES=1,3), lower heart rate variables (peak, average and
variation; p<0,01, ES>0,5), and higher execution inclination of
local oxygen saturation (p<0,05 and ES=1,0). In conclusion, the
time variations assessed do not alters power outcomes in female cyclists.
However, higher acute fatigue can be observed in the WAnT of 30 sec,
which suggests the use of the test of 20 sec to allow continue training
afterwards.

Abstract
Objective The aim of this study was to assess incidence, risk factors, and outcomes of distal recurrent tracheoesophageal fistula (RTEF) after repair of esophageal atresia (EA).
Methods Ethical consent was obtained. Data collection was done by review of hospital records of 286 patients (268 in-house and 18 referred) who underwent repair of type C or D EA from 1980 to 2021. Spitz class, long-gap (tracheoesophageal fistula at carina), fundoplication, leakage, and stricture were assessed as RTEF risk factors. Outcome measures were long-term closure of RTEF, retainment of native esophagus, and survival.
Results RTEF occurred in 23 patients (19 in-house) with type C (n = 22) or type D (n = 1) EA with median 4.4 (interquartile range [IQR]: 1.7–13) months after repair. Five patients had late RTEF 3.5 to 16 years after repair. Nineteen (7.3%) in-house patients developed RTEF. Presenting symptoms, age at diagnosis, and presence of anastomotic stricture (AS) are listed. No statistically significant risk factors were found, risk ratio of 0.5 to 2.7 (IQR: 0.1–8.7), p-value of 0.25 to 0.75. Detached closure clip and esophageal foreign body contributed to RTEF in two patients. Sixteen patients underwent rethoracotomy for closure of RTEF, 5 (22%) with AS eventually underwent esophageal reconstruction after a period with cervical esophagostomy. Two patients with late-manifested RTEFs underwent closure with laser cauterization. In 22 patients, treatment of RTEF succeeded, whereas 1 (4%) premature patient died of instant re-RTEF.
Conclusion RTEF had an incidence of 7% with diverse patterns of manifestation and predicting factors. Closure rate and patient survival were excellent, but RTEF with AS predicted loss of native esophagus.
Factor VIII and Factor IX Activity Measurements for Hemophilia Diagnosis and Related Treatments
Authors: Bowyer Annette E. , Gosselin Robert C. 
Published: December 2022

AbstractAccurate measurement of clotting factors VIII (FVIII) or IX (FIX) is vital for comprehensive diagnosis and management of patients with hemophilia A or B. The one-stage activated partial thromboplastin time (aPTT)-based clotting assay is the most commonly used method worldwide for testing FVIII or FIX activities. Alternatively, FVIII and FIX chromogenic substrate assays, which assess the activation of factor X, are available in some specialized laboratories. The choice of reagent or methodology can strongly influence the resulting activity. Variation between one-stage FVIII or FIX activities has been reported in the measurement of some standard and extended half-life factor replacement therapies and gene therapy for hemophilia B using different aPTT reagents. Discrepancy between one-stage and chromogenic reagents has been demonstrated in some patients with mild hemophilia A or B, the measurement of some standard and extended half-life factor replacement therapies, and the transgene expression of hemophilia A and B patients who have received gene therapy. Finally, the measurement of bispecific antibody therapy in patients with hemophilia A has highlighted differences between chromogenic assays. It is imperative that hemostasis laboratories evaluate how suitable their routine assays are for the accurate measurement of the various hemophilia treatment therapies.

Published: December 2022

AbstractAlström syndrome (AS) is a rare multisystem disorder characterized by cone-rod retinal dystrophy leading to vision loss, hearing deficiency, obesity, type 2 diabetes mellitus, and insulin resistance with hyperinsulinemia. The conditions include dilated cardiomyopathy, recurrent fibrotic pulmonary infections, and progressive renal, hepatic, and endocrinological dysfunction. Other clinical findings consist of thyroid problems, short height, and growth hormone insufficiency. In addition, patients present with normal IQ, but in some cases delay in psychomotor and cognitive development is described. There is no treatment for AS, and life expectancy is around 40 years. However, an early identification of the disease can help in reducing the progression to severe conditions and in ameliorating the patient's quality of life. Our intent was to analyze the clinical data in literature on AS and provide an up-to-date review.

A modular electromagnetic railgun accelerator facility named “RAFTAR” (i.e., Railgun Accelerator Facility for Technology and Research) has been commissioned and its performance has been characterized for high velocity impact testing on materials in a single-shot mode. In the first tests, RAFTAR demonstrated an acceleration of more than 1000 m/s for an 8 g solid aluminum-7075 armature projectile. The current fed was 220 kA, having a muzzle time of about 1.75 ms. It is a single pulse breech-fed rectangular bore (14 × 13 mm2) railgun, and its 1.15 m long barrel assembly consists of two parallel copper bars with an inter-gap of 13 mm that are encased within 50 mm thick high strength reinforced fiberglass sheets (Garolite G10-FR4) and bolted from both the sides. RAFTAR is powered by two capacitor bank modules that have a maximum stored energy of 160 kJ each (containing eight 178 μF/15 kV capacitors), two high power ignitron switches, and a pulse shaping inductor. To obtain consistent acceleration of the armature inside the barrel, reversal of driving current is prevented, and its pulse duration is stretched by tactical integration of the crowbar switch and bitter coil inductor in the circuit. Armature projectile velocity measurement in-bore and outside in free space was performed by the time-of-flight technique using indigenously made miniature B-dot sensors and a novel shorting-foil arrangement, respectively. The time resolved measurement of the in-bore armature evidenced a velocity-skin-effect in the high acceleration phase. There is good agreement between the experimentally measured and theoretically predicted efficiency, confirming the optimal choice of operating parameters. The conclusion summarizes important experimental findings and analyzes the underlying causes that limit the performance of railguns.
