Structure and functions of Yellow-breasted Boubou (Laniarius atroflavus) solos and duets
Authors: Wheeldon Amie , Szymański Paweł , Budka Michał , Osiejuk Tomasz S. 
Published: October 2020

Background
Birds have extremely well-developed acoustic communication and have become popular in bioacoustics research. The majority of studies on bird song have been conducted in the temperate zones where usually males of birds sing to attract females and defend territories. In over 360 bird species mostly inhabiting the tropics both males and females sing together in duets. Avian duets are usually formed when a male and female coordinate their songs. We focused on a species with relatively weakly coordinated duets, with male solo as the prevailing vocalisation type.

Methods
Instead of analysing a set of recordings spread over a long time, we analysed whole day microphone-array recordings of the Yellow-breasted Boubou (Laniarius atroflavus), a species endemic to West African montane rainforests. We described the structure of the solo and duet vocalisations and temporal characteristics of daily activity based on 5,934 vocal bouts of 18 focal pairs and their neighbours.

Results
Birds had small, sex specific repertoires. All males shared three types of loud whistles functioning as song type repertoires in both solos and duets. Females vocalised with five types of harsh, atonal notes with a more variable and usually lower amplitude. Three of them were produced both as solos and in duets, while two seem to function as alarm and excitement calls given almost exclusively as a solo. Solos were the most common vocalisation mode (75.4%), with males being more vocally active than females. Duets accounted for 24.6% of all vocalisations and in most cases were initiated by males (81%). The majority of duets were simple (85.1%) consisting of a single male and female song type, but altogether 38 unique duet combinations were described. Males usually initiated singing at dawn and for this used one particular song type more often than expected by chance. Male solo and duet activities peaked around dawn, while female solos were produced evenly throughout the day.

Discussion
Yellow-breasted Boubou is a duetting species in which males are much more vocal than females and duetting is not a dominating type of vocal activity. Duet structure, context and timing of daily production support the joint resource defence hypothesis and mate guarding/prevention hypotheses, however maintaining pair contact also seems to be important. This study provides for the first time the basic quantitative data describing calls, solos and duet songs in the Yellow-breasted Boubou.

Published: October 2020

Maltodextrins were prepared from sago starch in a twin screw extruder. A response surface design was used in the extrusion, which included the variations in the α-amylase (Termamyl 120L) concentrations of 12-24 g/kg dry starch, the moisture contents of 45-55%, and the screw speeds of 75-175 rpm. The product properties examined included dextrose equivalent (DE) values, and composition of malto-oligosaccharides of degree of polymerization 2 (DP2) to DP7 by using high performance liquid chromatography (HPLC). The result indicated that DE values ranged from 3.16 – 23.55 mg/g sample and the oligosaccharide component of DP5 was predominant in the samples. The possibility of using the products in food application was also discussed, including incorporating the maltodextrin in a food system as binder, bulking agent, flavor encapsulation, fat replacer, or other applications.

Published: October 2020

ObjectiveConcerns about severe acute respiratory syndrome coronavirus 2 (SARS–CoV‐2) infection may have led to changes or discontinuation of immunosuppressive medications among patients with systemic rheumatic disease. Our goal was to assess patients’ perspectives regarding medication modifications and deviations from planned uses during the height of the pandemic.MethodsAdult patients of 13 rheumatologists at an academic center with physician‐diagnosed rheumatic disease and prescribed disease‐modifying medications were interviewed by telephone and asked open‐ended questions about the impact of SARS–CoV‐2 on their medications. Responses were analyzed using content and thematic analyses to generate categories that described patterns of medication modification.ResultsA total of 112 patients (mean age 50 years, 86% women, 34% non‐White race or Latino ethnicity) with diverse diagnoses (30% lupus, 26% rheumatoid arthritis, 44% other) who were taking various medications were enrolled. Patients reported clinically relevant issues that were iteratively reviewed to generate unique categories of medication modification: medications and increased or decreased risk of SARS–CoV‐2 infection; role of hydroxychloroquine; maintaining medication status quo; role of glucocorticoids; increasing or decreasing existing medications in relation to clinical disease activity; postponing infusions; and medication plan if infected by SARS–CoV‐2. Some modifications were suboptimal for disease control but were made to mitigate infection risk and to minimize potential harm when patients were unable to obtain laboratory tests and physical examinations due to cessation of in‐person office visits.ConclusionDuring the height of the pandemic, substantial medication modifications were made that, in some cases, were temporizing measures and deviations from planned regimens. Future studies will assess short‐ and long‐term sequelae of these medication modifications.

AbstractThe design and benchtop operation of a wireless miniature epiretinal stimulator implant is reported. The implant is optically powered and controlled using safe illumination at near‐infrared wavelengths. An application‐specific integrated circuit (ASIC) hosting a digital control unit is used to control the implant's electrodes. The ASIC is powered using an advanced photovoltaic (PV) cell and programmed using a single photodiode. Diamond packaging technology is utilized to achieve high‐density integration of the implant optoelectronic circuitry, as well as individual connections between a stimulator chip and 256 electrodes, within a 4.6 mm × 3.7 mm × 0.9 mm implant package. An ultrahigh efficiency PV cell with a monochromatic power conversion efficiency of 55% is used to power the implant. On‐board photodetection circuity with a bandwidth of 3.7 MHz is used for forward data telemetry of stimulation parameters. In comparison to implants which utilize inductively coupled coils, laser power delivery enables a high degree of miniaturization and lower surgical complexity. The device presented combines the benefits of implant miniaturization and a flexible stimulation strategy provided by a dedicated stimulator chip. This development provides a route to fully wireless miniaturized minimally invasive implants with sophisticated functionalities.

Published: October 2020

AbstractLinear dynamic range (LDR) and weak‐light detection limit of photodetectors (PDs) directly determine the imaging resolution and signal‐to‐noise ratio (SNR) in weak‐light condition. Herein, an all‐inorganic perovskite PD is designed with a sandwich structure of NiOx/CsPbBr3/TiO2 (NCT). The CsPbBr3 perovskites are designed by a spin‐coating method, and NiOx and TiO2 layers are introduced by an atomic layer deposition (ALD) method. The optimized NCT PD exhibits outstanding performance with ultralow dark current (≈10−11 A), broad LDR (186.7 dB), and ultralow detection limit (857 pW cm−2). Significantly, a proof‐of‐concept optical imaging system has been demonstrated using the NCT PD as the sensor element, which shows high resolution and high SNR even under weak‐light condition. Furthermore, as a demo application, a solution is provided to the identification problem of 2D barcode under a weak‐light environment as low as 4 nW cm−2. The results show promising applications of the all‐inorganic perovskite PD serving as a weak‐light imaging sensor, with unique potential for low‐cost manufacturing of large‐area optoelectronic devices.
Rural–Urban Differences in Health Care Access and Utilization under the Medicaid Expansion
Authors: Mandal Bidisha 
Published: October 2020

AbstractThe Affordable Care Act's Medicaid expansion ushered in substantial increases in enrollment in the public insurance program. I analyzed rural–urban differences in access to health insurance, financial access to primary care providers, use of preventive care, and use of emergency department for medical reasons that did not lead to hospitalization. Low‐income rural residents were found to have greater reduction in likelihood of uninsurance than their urban counterparts. While an increase in the likelihood of routine check‐ups was found to be significant only among rural residents, a decrease in the likelihood of repeated visits to the emergency departments for nonurgent reasons was only significant among the urban population. I highlight the importance of understanding rural experiences to reduce rural–urban health disparities.
Association between age at menarche and body mass index, waist circumference, waist to hip ratio, and waist to height ratio in adult women
Authors: Żurawiecka Martyna , Wronka Iwona 
Published: October 2020

AbstractObjectivesThe aim of the present study was to examine associations between age at menarche and body mass index (BMI), waist circumference (WC), waist‐to‐height ratio (WHtR), and waist‐to‐hip ratio (WHR) in young adult women.MethodsAnthropometric data and age at menarche information were collected in two cross‐sectional surveys conducted in the years 2004‐2006 (Cohort 1) and 2016‐2018 (Cohort 2). A total of 2419 women, aged 19‐24 years., were included.ResultsStatistically significant relationships between age at menarche and BMI, WHtR, and WC were observed. The values of the anthropometric parameters decreased with increasing age at menarche. The onset of menstruation before the age of 12 years. was linked to a heightened risk of overweight and obesity (BMI ≥ 25) and abdominal obesity defined as WC > 80 cm and/or WHtR ≥ 0.5. First menstruation after the age of 14 y. was associated with a lower risk of overweight and obesity (BMI ≥ 25, WC > 80 cm and/or WHtR ≥ 0.5), as well as a higher risk of being underweight (BMI < 18.5 and/or WHtR < 0.4). Associations between anthropometry and menarcheal timing were stronger in Cohort 1.ConclusionBoth early and late onset of menarche are associated with abnormal body composition: Early menarche is associated with overweight, while later maturing girls have a heightened risk of underweight.

Published: October 2020

AbstractA novel strategy to engineer biodegradable halochromic film based on poly (lactic acid) (PLA) for pH sensorial substances was presented. The effect of polyethylene glycol (PEG) compositions and dye amount on the efficiency of halochromic pH film was observed. The interactions between PLA, PEG, and dye was evidence by Fourier transform infrared. UV–VIS results indicated the sensitivity of the halochromic film through color changes. Mechanical performance was investigated by tensile testing to assess the potential of the halochromic film. It was found that the halochromic pH film has a clear color response from yellow to purple at pH 3–11 with a rapid response time within a minute. The results also revealed that varying content of PEG showed a significant effect on response time compared with varying dye compositions. PLA/PEG film and dye formed new interactions where PEG increased the free volume of PLA and made it possible for the PEG and the dye to diffuse and entrap between PLA chain. In term of the film strength, the addition of PEG and dye improved the flexibility of PLA film, which enables great potential in many applications such as medical, textile, and packaging.

Published: October 2020

AbstractThe introduction of chalcogen atoms into a polycyclic aromatic hydrocarbon structure is an established method to tune material properties. In the context of corannulene (C20H10), a fragment of fullerene C60, such structural adjustments have given rise to an emerging class of functional and responsive molecular materials. In this minireview, our aim is to discuss the synthesis and properties of such chalcogen (sulfur, selenium, and tellurium) derivatives of corannulene.
Fault diagnosis for semilinear distributed parameter systems with actuator/sensor based on iterative learning control
Authors: Zhang Jianxiang , Cui Baotong , Dai Xisheng 
Published: October 2020

AbstractThis paper focuses on the fault diagnosis problem for a class of semilinear distributed parameter systems with actuator and sensor. To diagnose the actual fault, a fault estimator is designed by using an introduced virtual fault for this system. Based on the semigroup theory and λ‐norm, the residual signal is used in the PD‐type iterative learning control scheme to regulate the introduced virtual fault, making the virtual fault track the practical fault. Then, the goal of fault diagnosis is obtained. Finally, the effectiveness of the proposed method is tested on a Fisher equation and applied to a class of typical chemical industry processes.

Authors: Reiterer Michael , Strauss Alfred , Kari Hannes 
Published: October 2020

AbstractEs werden neue innovative Ansätze zur performancebasierten Zustandsbeurteilung und Lebensdauerprognose von Ingenieurkonstruktionen auf Grundlage eines hybriden und modellbasierten Zuverlässigkeitsindex vorgestellt. Die Methode beruht auf der Zusammenführung der Ergebnisse aus rein visuellen Zustandsprüfungen von Ingenieurkonstruktionen mit vorhandenem Expertenwissen aus Versuchen und Berechnungen. Mittels Methoden der Künstlichen Intelligenz (KI) werden die Zustandsklassen aus der heuristischen visuellen Inspektion und das vorhandene Expertenwissen zur verfeinerten Ermittlung des zustandsabhängigen Zuverlässigkeitsindex unter Berücksichtigung der entsprechenden Schadensfolgeklassen (CCn) bei einem bestimmten Lebensalter der Konstruktion herangezogen. Es werden vier unterschiedliche Modelle für die Prognose der zukünftig sich ergebenden Zustandsentwicklung/Degradation und der zu erwartenden Lebensdauer der betrachteten Ingenieurkonstruktion vorgestellt. Diese methodischen Ansätze werden am Beispiel einer bei Zugvorbeifahrt hochgradig dynamisch beanspruchten Lärmschutzwandkonstruktion der Bahn zur Zustandsbeurteilung und Lebensdauerprognose skizziert.
Can jaw position affect the fine motor activity of the hand during writing?
Authors: Alghadir Ahmad H. , Zafar Hamayun , Iqbal Zaheen A. 
Published: October 2020

AbstractBackgroundJaw and neck systems have been shown to be functionally related and changes in either system can modulate gross motor functions, such as posture control. It remains to be seen if any change in jaw position can affect fine motor skills. The objective of this study was to determine the effect of resting, open and clenched jaw positions on various handwriting parameters while standing on firm and unstable surfaces.MethodsHandwriting samples were collected from 36 healthy male participants (age, 15–35 years) using a digitizer tablet (WACOM Intuos 4) with noninking pen in the resting, open and clenched jaw positions while standing on firm and unstable surfaces. The measured handwriting parameters included duration, vertical size, horizontal size, absolute size, average absolute velocity, and absolute jerk. Recordings and analyses were performed using NeuroScript MovAlyzeR software.ResultsAll handwriting parameters varied among the resting, open, and clenched jaw positions on both the firm and unstable surfaces. However, based on statistical analyses, there were no significant differences in the handwriting parameters among three jaw positions on both surfaces (p > .05).ConclusionThis study revealed that all handwriting parameters varied among the resting, open, and clenched jaw positions on both the firm and unstable surfaces, showing that change in the jaw motor system may potentially affect the fine motor skills. However, on statistical analysis, there was no significant effect of 3 studied jaw positions on fine motor skills as seen on gross motor skills among healthy individuals.
Coronary interventions among patients with hepatic insufficiency: Encouragement to avoid a jaundiced view
Authors: Whiteside Hoyle L. , Moliterno David J. 
Published: October 2020

Key Points
This observational study from the National Inpatient Sample found a temporal increase in percutaneous coronary interventions (PCI) among patients with liver cirrhosis.
In a propensity matched analysis, patients with underlying hepatic insufficiency demonstrated a predisposition to peri‐operative acute kidney injury and required greater resource allocation associated with higher in‐hospital mortality and costs.
Despite a higher‐risk profile associated with chronic hepatic insufficiency, contemporary technologies and techniques for PCI, including drug‐eluting stents, should not be withheld from this population.

A step toward physiologically guided chronic limb‐threatening ischemia intervention
Authors: Winscott John G. , Hillegass William B. 
Published: October 2020

Key Points
Spatial and quantitative measures of end‐tissue perfusion and oxygenation are an unmet need in the care of chronic limb‐threatening ischemia (CLTI) patients.
Pedal artery sheath measurements of pedal pressure are feasible, safe, and predictive of limb survival.
Extending this concept to other endovascular access sites and open surgery, multiple novel approaches may soon permit real‐time intraprocedural physiological measures to quantitatively inform revascularization and long‐term management of CLTI patients.
One in one equals two
Authors: Ooi Yinn Shaung , Gray William A. 
Published: October 2020

Key Points
Significant mitral regurgitation (MR) is common in patients undergoing valve‐in‐valve transcatheter aortic valve replacement (VIV‐TAVR) for aortic bioprosthetic structural valve deterioration.
The current study suggests that mild and moderate MR generally improves after VIV‐TAVR, and does not appear to impact clinical outcomes.
Further research is needed to refine these findings.

Authors: Rodriguez‐Paz Enrique , Heuser Richard R. 
Published: October 2020

Key Points
It is almost impossible to differentiate Takotsubo syndrome from acute coronary syndrome (ACS) on initial presentation.
One can usually elicit a history of a sudden emotional or physically stressful event suffered by the patient before presenting with Takotsubo syndrome.
Takotsubo syndrome more often occurs in females.
New evidence suggests that Takotsubo syndrome can coexist with ACS.

Local structure graph models with higher‐order dependence
Authors: Casleton Emily M. , Nordman Daniel J. , Kaiser Mark S. 
Published: October 2020

AbstractLocal structure graph models (LSGMs) describe random graphs and networks as a Markov random field (MRF)—each graph edge has a specified conditional distribution dependent on explicit neighbourhoods of other graph edges. Centred parameterizations of LSGMs allow for direct control and interpretation of parameters for large‐ and small‐scale structures (e.g., marginal means vs. dependence). We extend this parameterization to account for triples of dependent edges and illustrate the importance of centred parameterizations for incorporating covariates and interpreting parameters. Using a MRF framework, common exponential random graph models are also shown to induce conditional distributions without centred parameterizations and thereby have undesirable features. This work attempts to advance graph models through conditional model specifications with modern parameterizations, covariates and higher‐order dependencies.
