Context. Barium (Ba) stars are polluted by material enriched in the slow neutron capture (s-process) elements synthesised in the interior of their former asymptotic giant branch (AGB) companion star, which is now a white dwarf.
Aims. We aim to compare individual Ba star abundance patterns to AGB nucleosynthesis model predictions to verify if the AGB model mass is compatible with independently derived AGB mass, which was previously estimated using binary parameters and Gaia parallax data.
Methods. We selected a sample of 28 Ba stars for which both self-consistent spectroscopic observation and analysis were performed and, additionally, stellar mass determinations, via positioning the star on the Hertzsprung-Russell (HR) diagram and comparing with evolutionary tracks are available. For this sample of stars, we considered both previously (Y, Zr, Ce, and Nd) and recently derived (Rb, Sr, Nb, Mo, Ru, La, Sm, and Eu) elemental abundances. Then, we performed a detailed comparison of these s-process elemental abundances to different AGB nucleosynthesis models from the Monash and the FRUITY theoretical data sets. We simplified the binary mass transfer by calculating dilution factors to match the [Ce/Fe] value of each star when using different AGB nucleosynthesis models, and we then compared the diluted model abundances to the complete Ba-star abundance pattern.
Results. Our comparison confirms that low-mass (with initial masses roughly in the range 2−3 M⊙), non-rotating AGB stellar models with 13C as the main neutron source are the polluters of the vast majority of the considered Ba stars. Out of the 28 stars, in 21 cases the models are in good agreement with both the determined abundances and the independently derived AGB mass, although in 16 cases higher observed abundances of Nb, Ru, Mo, and/or Nd, Sm than predicted were present. For three stars, we obtain a match to the abundances only by considering models with masses lower than those independently determined. Finally, four stars show much higher first s-process peak abundance values than the model predictions, which may represent the signature of a physical (e.g. mixing) and/or nucleosynthetic process that is not represented in the set of models considered here.

Published: February 2022

EinleitungDer fibro-ossäre Pseudotumor der Finger (FOPD = fibro-osseous pseudotumor of the digits) ist unter den Handtumoren insgesamt als auch unter den benignen Handtumoren eine seltene Entität. FOPD können sowohl klinisch als auch radiologisch eine maligne Neoplasie nachahmen. Hauptsächlich tritt dieser Tumor bei jüngeren Erwachsenen, vorwiegend Frauen, auf. Bis dato ist eine maligne Transformation nicht beschrieben. Allerdings führen klinische und histologische Befunde fälschlicherweise immer wieder zur Diagnose eines bösartigen Tumors.

Published: February 2022

Zusammenfassung
Hintergrund: Die Vielseitigkeit der distalen Radiusfrakturen, der Diagnostik- und Therapiemöglichkeiten birgt großes Potenzial für eine mangelhafte Genesung mit der Folge der Patientenunzufriedenheit. Das Ziel dieser Studie ist die Evaluierung distaler Radiusfrakturen, die sekundär zu juristischen Streitfällen führten, um Rückschlüsse für Optimierungs-. bzw. Präventionsmaßnahmen zur Steigerung der Patientenzufriedenheit und Vermeidung von Folgekosten zu ziehen
Material und Methoden: Akten und Patientendaten aller juristisch behandelter Streitfälle in Bezug auf distale Radiusfrakturen eines öffentlichen Krankenhausbetreibers wurden im Zeitraum 2007 bis 2017 eingesehen und einer deskriptiven Statistik unterzogen.
Ergebnisse: Insgesamt wurden 35 Fälle mit Beschwerden in Bezug auf Behandlungs-, Kommunikations- und Folgeschäden identifiziert, die durch die deskriptive Statistik weiter analysiert und nach Schwerpunktthemen weiter aufgeschlüsselt wurden.
Schlussfolgerung: Komplikationen und Spätfolgen bei distaler Radiusfraktur sind nicht gänzlich vermeidbar, Kommunikationsdefizite und Behandlungsverzögerungen jedoch weitestgehend schon. Eine Reflexion der diagnostischen und therapeutischen, aber insbesondere der interpersonellen Herangehensweise erscheint im Sinne einer gesteigerten Patientenzufriedenheit unabdingbar.

Published: February 2022

Background Multiple computer-aided systems for polyp detection (CADe) have been introduced into clinical practice, with an unclear effect on examiner behavior. This study aimed to measure the influence of a CADe system on reaction time, mucosa misinterpretation, and changes in visual gaze pattern.
Methods Participants with variable levels of colonoscopy experience viewed video sequences (n = 29) while eye movement was tracked. Using a crossover design, videos were presented in two assessments, with and without CADe support. Reaction time for polyp detection and eye-tracking metrics were evaluated.
Results 21 participants performed 1218 experiments. CADe was significantly faster in detecting polyps compared with participants (median 1.16 seconds [99 %CI 0.40–3.43] vs. 2.97 seconds [99 %CI 2.53–3.77], respectively). However, the reaction time of participants when using CADe (median 2.90 seconds [99 %CI 2.55–3.38]) was similar to that without CADe. CADe increased misinterpretation of normal mucosa and reduced the eye travel distance.
Conclusions Results confirm that CADe systems detect polyps faster than humans. However, use of CADe did not improve human reaction times. It increased misinterpretation of normal mucosa and decreased the eye travel distance. Possible consequences of these findings might be prolonged examination time and deskilling.
Palladium-Catalyzed Cyanation of Arenediazonium Tetrafluoroborate Derivatives with 2-(Piperidin-1-yl)acetonitrile as the Cyano Source

Published: February 2022

AbstractThe present study describes the one-pot palladium-catalyzed cyanation of commercially available aryldiazonium tetrafluoroborate derivatives with 2-(piperidin-1-yl)acetonitrile (an organic cyano reagent) under mild conditions. This process utilizes a Pd/(Me3Si)2 system and is applied to a wide scope of aromatic diazonium substrates to give the corresponding nitrile-containing products in moderate to high yields (59–92%). This methodology is employed for the preparation of etravirine, a drug used for the treatment of HIV, and for transformations of 1H-indole-2-carbonitrile into compounds that are used as a NMDA receptor antagonists and that have high potential against mutant HIV strains. The mechanism proposed for this Pd-catalyzed cyanation involves cyanide ions, as confirmed using indicator paper.

Abstract
Objective Extraintestinal Escherichia coli isolates are the most common gram-negative pathogens in humans and cause urinary tract infections, sepsis, neonatal meningitis, and others. The aim of this study was to investigate the rates of antibiotic resistance and virulence factors (kpsM II, neuc K1, hlyF, fyuA, afa/draBC, sat, chuA, fimH, tsh, yfcv, ibeA, traT, iucD, usp, iutA, cnf1, hlyA, papC, sfa/focDE, and ompT) of E. coli strains isolated from blood and urine samples.
Methods A total of 150 E. coli strains isolated from blood and urine samples sent to the Microbiology Laboratory, Faculty of Medicine Hospital, Selcuk University were included in the study. The identification and antibiotic susceptibility tests were performed with the VITEK 2 automated system. Multiplex polymerase chain reaction was used to detect the virulence genes.
Results Although the highest antibiotic resistance rate found was against ampicillin (73.3%), the lowest rates were against ertapenem and meropenem (0.7%). Extended-spectrum β-lactamase positivity was 38% in E. coli blood isolates and 29% in urine. The highest rates of virulence genes were detected in fimH gene (92%). iutA gene was 91.3%, traT 76%, fyuA 50%, chuA 54.7%, iucD 46.7%, ompT 32.7%, yfcv 31.3%, hlyF 28.7%, sat 22%, papC and sfa/focDE 20%, kpsM II 19.3%, neuc K1 14.7%, tsh 13.3%, cnf1 6.7%, afa/draBC 6%, ibeA 5.3%, usp 4.7%, and hlyA 3.3%. kpsM II, tsh, hlyA, papC, sfa/focDE, and ompT genes were higher in blood isolates.
Conclusion High antibiotic resistance rates and virulence genes were detected in E. coli strains in Konya, Turkey. This is the first study in Turkey where both a large number and a variety of virulence factors were investigated and compared. Multicenter studies are needed to better understand E. coli virulence.

AbstractIn this article, our primary objective was to investigate the prevalence and etiology of extubation failure (EF) in patients following cardiac surgery for congenital heart disease. Secondarily, we examined the association of different risk factors with EF. This was single-center retrospective study in a 27-bed cardiac intensive care unit at a quaternary children's hospital. All patients between 0 and 18 years of age who underwent congenital cardiac surgery from January 2008 to September 2019 were included. During the study period, among 8,750 surgical encounters, 257 (2.9%) failed extubation, defined as reintubation within 48 hours from extubation. EF patients were younger, smaller, more likely to have genetic syndromes, higher Society of Thoracic Surgeons and the European Association for Cardio-Thoracic Surgery (STAT) mortality scores, single-ventricle physiology, longer cardiopulmonary bypass (CPB) and cross-clamp (XC) times, longer mechanical ventilation (MV) duration, and higher mortality (p <0.05). In a univariate analysis, EF patients when compared to matched controls by age, gender, and STAT score, and genetic syndrome, particularly heterotaxy, were associated with increased odds of EF (p <0.05). In a multivariable logistic regression of the entire cohort, the presence of any genetic syndrome was associated with higher odds of EF (p <0.05). In a subgroup of neonates, a univariate analysis was performed and multivariable analysis was attempted, but both did not achieve statistical significance. In summary, EF after congenital cardiac surgery is associated with younger age, lower weight, single-ventricle physiology, longer CPB and XC times, longer duration of MV, and genetic syndromes. Patients failing extubation have increased morbidity and mortality. Recognition of these risk factors may provide clinicians the ability to identify patients at high risk allowing for timely intervention to limit adverse outcomes.

Published: February 2022

AbstractIt is important to assess the patient satisfaction with shape and function by patient-reported outcome measures (PROMs) following structural or dorsal preservation rhinoplasty (DPR) techniques on the middle nasal vault. To analyze the results of different middle vault rhinoplasty techniques with multiple PROMs and compare their differences according to the findings of PROMs. Four different techniques were performed for the middle vault: spreader graft, L-strut graft, DPR with high strip (DPRwHS), DPR with low strip. The outcomes were evaluated preoperatively, 2 and 12 months postoperatively with the following PROMs: Nasal Obstruction Symptom Evaluation (NOSE), Rhinoplasty Outcomes Evaluation, and Standardized Cosmesis and Health Nasal Outcomes Survey. This study included 129 patients. All techniques provided significant improvements in all PROMs (p < 0.001), except DPRwHS in NOSE. Between postoperative short- and longer-term, no significant differences were observed in DPR groups (p > 0.05), unlike structural techniques. In this comparative study of different middle nasal vault rhinoplasty techniques, we did not detect a difference in the improvement of the patient-reported outcomes of DPR techniques from as early as 2 months to 1 year postoperative.

Abstract
Purpose This study aims to evaluate the relationship between inferior mesenteric artery (IMA) diameter and risk of type II endoleak.
Subjects and Methods: A retrospective study design to review all EVARs performed over a 4-year period at a tertiary care center. Out of the total cohort of 400 patients who underwent EVAR, 41 patients (10.3%) developed type II endoleak. The mean IMA ostial diameter for patients with type II endoleak secondary to IMA contributories was 4mm, while the mean IMA diameter for patients with lumbar arteries contributing to the type II endoleak was 3.7mm.
Results Statistical analysis using a paired t-test did not show a statistically significant difference in the IMA ostial diameter between the two groups.
Conclusion There is no significant correlation between preprocedural IMA ostium diameter and type II endoleak development and hence, preprocedural IMA embolization is not an appropriate prophylactic management strategy.
The Novel Use of a Synthetic Amino Acid Analog in the Management of Menkes' Disease
Authors: Jafar Bedour , Sharma Kamal , Sheikh Ameera , Maertens Paul 
Published: February 2022

AbstractMenkes' disease is a rare X-linked neurodegenerative disorder due to an ATPA7 mutation. This mutation results in a defective copper transport into the lumen of the trans-Golgi network (TGN) of all tissues, except the liver. As the liver remains effective in transporting copper into the TGN, parenteral copper administration is successful in normalizing copper and ceruloplasmin levels. In addition, such treatment improves function of cuproenzymes in the nucleus, cytosol, and mitochondria. However, ATPA7 mutation results in a deficient dopamine β-hydroxylase, a cuproenzyme needed to convert dopamine to norepinephrine (NE). Here, we present the novel use of the synthetic amino acid analog, droxidopa, a prodrug to NE in the management of Menkes' disease. In our 6-year-old Menkes' disease patient treated with daily parenteral copper infusion, we studied clinical features and urine catecholamines levels at baseline and after initiating droxidopa therapy. NE deficiency at baseline was associated with inattention, hypothermia, and dysautonomia. After correction of NE deficiency, the child's symptoms improved. Epinephrine levels remained low. In Menkes' disease, NE deficiency persists after normalization of copper and ceruloplasmin levels. Droxidopa therapy is successful in correcting NE levels and improving quality of life. Further studies are needed.
The increment of the temperature of maximum density of water by addition of small amounts of tert-butanol: Experimental data and microscopic description revisited
Authors: González-Salgado D. , Troncoso J. , Lomba E. 
Published: February 2022

The temperature of maximum density, TMD, of aqueous solutions of tert-butanol has been experimentally determined in the pressure range of 0–300 bars and up to 0.025 tert-butanol mole fraction. At atmospheric pressure, this quantity increases for low alcohol mole fractions, reaches a maximum at intermediate concentrations, and then quickly falls. The new experimental results are basically in agreement with previous data in the literature by Wada and Umeda [G. Wada and S. Umeda, Bull. Chem. Soc. Jpn. 35, 646 (1962)], except at very low mole fractions, where these authors reported a stronger density anomaly. Our measurements also confirm the known effect of pressure, p, on the variation in the temperature of maximum density with respect to that of pure water, ΔTMD: this quantity increases with p over the whole composition range. In addition, molecular dynamics simulations were performed between 0 and 2000 bars and from 238 to 328 K using a recently proposed model for the tert-butanol/water system. It has been found that our model reproduces qualitatively the experimental behavior of the ΔTMD, but for pressures above 1000 bars. A detailed structural analysis showed that the addition of tert-butanol promotes the low density water structure, and this promotion is somewhat hampered as the temperature increases at high pressure (ΔTMD &gt; 0) and mostly independent of temperature at low pressures (ΔTMD &lt; 0). Our analysis shows that the ultimate factor determining changes in the TMD is the temperature dependence of the low density water structure enhancement. We have also carried out a local structure analysis in which in addition to solid-like structures, low density liquid water ones have also been considered.
Visual object categorization in infancy
Authors: Spriet Céline , Abassi Etienne , Hochmann Jean-Rémy , Papeo Liuba 
Published: February 2022

SignificanceCategorization is the basis of thinking and reasoning. Through the analysis of infants’ gaze, we describe the trajectory through which visual object representations in infancy incrementally match categorical object representations as mapped onto adults’ visual cortex. Using a methodological approach that allows for a comparison of findings obtained with behavioral and brain measures in infants and adults, we identify the transition from visual exploration guided by perceptual salience to an organization of objects by categories, which begins with the animate–inanimate distinction in the first months of life and continues with a spurt of biologically relevant categories (human bodies, nonhuman bodies, nonhuman faces, small natural objects) through the second year of life.
Default gender in Belgian Dutch
Authors: Vanden Wyngaerd Emma 
Published: February 2022

AbstractGrammatical gender has been thoroughly investigated in codeswitching (CS) research. When (only) one of the languages involved in CS has grammatical gender, it has repeatedly been shown that (simultaneous) bilinguals assign default gender to a codeswitched noun from a genderless language (Liceras et al. 2008;Valdés Kroff et al. 2017;Parafita Couto 2019). For Spanish, “[t]here is little doubt that masculine is the unmarked or default gender” (Harris, 1991, 43). When looking at Belgian Dutch however, the picture is a bit more complicated, as it is not clear which determiner is unmarked for gender.Rooryck (2003)argues that the neuter gender is the under-specified category, while the masculine and feminine are marked for gender. This would predict that English nouns would be preceded by a neuter determiner when incorporated in a Belgian Dutch sentence. However, it seems to be the case that masculine, rather than neuter, is the preferred determiner for English codeswitches into Dutch. This paper reports on an acceptability judgment task in which simultaneous bilinguals were asked to rate (Belgian) Dutch sentences containing an English noun on a 7 point scale. Results surprisingly show a preference for feminine gender, in addition to neuter being dispreferred. I speculate that this unexpected result is due to influence from Standard Dutch.
Quasiperiodic oscillations from noncommutative inspired black holes
Authors: Rayimbaev Javlon , Bokhari Ashfaque Hussain , Ahmedov Bobomurat 
Published: February 2022

Abstract
We investigate the dynamics of test particles in the spacetime of noncommutative inspired black holes (NCi BHs). In this context, we first analyse spacetime properties of the NCi BHs together with innermost stable circular orbits (ISCOs) for the particles. It is observed that whereas the ISCO radius does not depend on the NC parameter, the frequencies of the Keplerian orbits and harmonic oscillations are NC parameter dependent. As an application, we consider quasiperiodic oscillations (QPOs) to test effects of the NC gravity around the BHs using twin-peak QPOs frequencies. It is found that the frequency changes even in the presence of the critical NC parameter are smaller than the error in the frequency measurements. The method developed for testing gravity using data from twin peak QPOs may also be applied to other alternate theories of gravity to obtain restrictions on the central BH parameters. We show that the orbits of QPOs lie near ISCO. This assumption may be helpful in solving the ISCO measurement problems in astrophysical observations. In addition, we determine the mass of the central BH in microquasar GRS 1915-105 and the QPO orbit in both the relativistic precession and warped disk models. It is shown that these parameters do not depend on the quantum corrections in the NC gravity. Lastly, we investigate the gravitational capture cross-section for photons and show that the effect of the NC parameter is also less than the error in shadow measurements of the supermassive BH (SMBH) Messier 87 (M87).
Analytical theory of enhanced Bose–Einstein condensation in thin films
Authors: Travaglino Riccardo , Zaccone Alessio 
Published: February 2022

Abstract
We present an analytically solvable theory of Bose–Einstein condensation (BEC) in thin film geometries. Analytical closed-form expressions for the critical temperature are obtained in both the low-to-moderate confinement regime (where the film thickness L is in the order of microns) as well as in the strong confinement regime where the thickness is in the order of few nanometers or lower. The possibility of high-temperature BEC is predicted in the strong confinement limit, with a square-root divergence of the critical temperature T
c ∼ L
−1/2. For cold Bose gases, this implies an enhancement up to two orders of magnitude in T
c for films on the nanometer scale. Analytical predictions are also obtained for the heat capacity and the condensate fraction. A new law for the heat capacity of the condensate, i.e. C ∼ T
2, is predicted for nano-scale films, which implies a different λ-point behavior with respect to bulk systems, while the condensate fraction is predicted to follow a

Nonstandard interactions and sterile neutrinos in super-weak U(1) extension of the standard model
Authors: Kärkkäinen Timo J , Trócsányi Zoltán 
Published: February 2022

Abstract
The super-weak force is a minimal, anomaly-free U(1) extension of the standard model (SM), designed to explain the origin of (i) neutrino masses and mixing matrix elements, (ii) dark matter, (iii) cosmic inflation, (iv) stabilization of the electroweak vacuum and (v) leptogenesis. We discuss the neutrino sector of this model in detail and study the allowed parameter space of the neutrino Yukawa matrices and mixing matrix elements. The model generates nonstandard neutrino interactions, whose allowed experimental limits are used to constrain the parameter space of the model. We provide benchmark points in the relevant parameter space that fall within the sensitivity region of the SHiP and MATHUSLA experiments.
