AbstractExamination of the spawning and maturity traits of coexisting Platycephalus caeruleopunctatus, Platycephalus grandispinis and Platycephalus richardsoni (Pisces: Platycephalidae) in coastal waters of southeastern Australia identified many commonalities. Each species was gonochoristic, reproductively active for a prolonged period each year, displayed asynchronous oocyte development with indeterminate fecundity and thus likely spawned multiple times throughout each spawning season. Males of all three species matured at smaller total lengths and younger ages than females, with skewed sex ratios reflecting divergent growth characteristics between sexes. Reproductive isolation among species is likely maintained through behavioural and morphological factors as well as species‐specific depth‐related separation of reproductively active individuals. General similarities in the reproductive strategies of each species and with other sympatric coastal teleosts suggest similar ecological adaptations to a variable coastal environment.

AbstractPurposeTo evaluate the efficacy of concentrated growth factor (CGF) injections in patients with androgenic alopecia.MethodsVenous blood of 60 patients (aged 18–55 years old with a mean age of 38 years) with androgenic alopecia who were treated from September 2017 to September 2019 were collected to prepare CGF. 0.1 ml CGF was injected into the alopecia area with an interval of 30–35 days for a total of 6 times. The evaluation was performed before treatment and at 1, 3, and 6 months after the first injection and 3 and 6 months after the last injection.ResultsAmong the 60 patients, 58 cases received 6 treatments completely, 52 cases showed significant improvement, 8 cases improved, and no ineffective or worsening cases were found. Among the 58 patients, hair density, hair follicle density, and hair diameter increased significantly. Furthermore, the hair status of all patients was improved to varying degrees during the 6‐month follow‐up from the digital photographs. No complications such as redness, swelling, infection, and ulceration were found in the injection area, and the patient satisfaction was 93% (56/60).ConclusionConcentrated growth factor treatment can significantly improve the symptoms of hair loss and increase hair diameter in patients with androgenic alopecia. It is effective, safe, and worth popularizing.
Trusting without a Safety Net: The Peril of Trust in Base of the Pyramid Economies

Published: May 2022

AbstractIn high‐transaction‐cost environments, such as the world's poorest base‐of‐the‐pyramid economies (BOP), trust helps entrepreneurs form partnerships while conserving resources related to monitoring, contracting, and other transaction costs. However, trust can also expose entrepreneurs to their partners' opportunism. In developed economies, effective and consistent legal systems can protect against such opportunism. But what happens when formal institutions are ineffective and inconsistent, as is common in BOP economies, and how does trust influence entrepreneurs' performance subsequent to forming partnerships? We answer these questions, drawing on a sample of 338 entrepreneurs in the Kingdom of Eswatini (formerly known as Swaziland). We find that entrepreneurs' trust has a negative effect on business operating performance, indicating that, given the legal systems in the BOP context, trusting entrepreneurs bear more fully the brunt of opportunism. However, this negative effect can be mitigated when entrepreneurs register their businesses with the government and pay taxes. We also find that, for entrepreneurs who earn income from other businesses, the negative effect of trust on performance is stronger. We found no moderating effect related to entrepreneurs' education.

Published: May 2022

AbstractIntroductionDisorders of gut‐brain interaction (DGBI) are highly prevalent, estimated to affect about 40% of the global population. Patients with DGBI are still inadequately treated and face stigma which adversely impacts their disease course.MethodsA 12‐question multiple‐choice anonymous survey was distributed electronically to all adult gastroenterology fellowship program directors across the United States. Data were collected on demographics, training, attitudes, and knowledge in managing patients with DGBI.Results9.8% and 15.9% of all trainees reported that their attendings and peers often demonstrated a dismissive attitude towards patients with DGBI, respectively. 21.4% of all trainees often felt frustrated or burned out when seeing patients with DGBI with increasing odds of burnout by years of training (OR 4.4 for F3 trainees, trainees in their third year of training). Significantly, more female trainees reported frustration and burnout when seeing patients with DGBI (p = 0.005). 28.6% of all trainees report they often do not want to see patients with DGBI in their outpatient GI practice, including 39.6% of F3 trainees. 27.1% of F3 trainees reported that they were uncomfortable with titrating neuromodulators and only 31.6% of all trainees were comfortable knowing when to refer to a gastropsychologist.DiscussionMany trainees expressed some unwillingness and discomfort in managing patients with DGBI. Potential interventions will require a multi‐pronged and longitudinal approach with education and training initiatives at the trainee level and beyond and exploring systemic healthcare delivery innovations to remove barriers.

AbstractBackgroundChronic Pseudomonas aeruginosa colonization (Pa‐CC) affects cystic fibrosis (CF) progression, including pulmonary exacerbations and pulmonary function tests. There are few studies of the effects of eradication protocols on colonization time. Here, we aimed to evaluate the effect of eradication regimens on chronic colonization and assess the impact of Pa‐CC on body mass index, lung functions, and pulmonary exacerbations.MethodsA retrospective review was conducted of medical records, over a period of 11 years, of children aged under 18 years with CF who had Pa‐CC in our tertiary care pediatric hospital.ResultsPseudomonas aeruginosa was detected in 215 of our patients with CF during the study period. Forty‐four patients with Pa‐CC were recruited for the study. The eradication treatment for the initial acquisition of P. aeruginosa was inhaled antibiotics in 27 (61.4%) patients; the remainder were given intravenous antibiotics. It was observed that eradication treatment with either IV or inhaled antibiotics did not affect the time between the P. aeruginosa and the time of Pa‐CC(P = 0.791). There was a non‐significant decrease in the body mass index z‐score from the Pa‐IA to the last visit(P = 0.27), a significant decline in forced expiratory volume in 1 s (FEV1%) (P = 0.01) over time, and the annual number of exacerbations after colonization was significantly higher than before colonization (P = 0.03).ConclusionsThere was no difference between eradication regimens in delaying the age at Pa‐CC. Pseudomonas aeruginosa colonization in patients with CF was also associated with poorer lung functions, lower body mass index, and more pulmonary exacerbation regardless of mucoid type. Consequently, to slow the progression of lung disease, we must prevent Pa‐CC, which we can achieve with early eradication. Despite conventional eradication protocols, future studies need to evaluate those who fail to clear P. aeruginosa.
Adaptive digital elevation models construction method based on nonparametric regression

AbstractInterpolation is one of the most critical factors affecting the quality of digital elevation models (DEM) generated from sampling point data. However, existing methods have not taken into full account that the interpolation function should be consistent with the density and direction characteristics of sampling points. Therefore, an adaptive DEM construction method based on nonparametric regression (AdpNPR‐DEM) is proposed, which incorporates an adaptive kernel that changes according to local landform types. The method first estimates local terrain features, and second the dominant orientation of the local gradients. The orientation information adaptively “steers” the local kernel to produce elongated, elliptical contours that spread along the directions of local terrain features. The effectiveness of the AdpNPR‐DEM is verified based on directional features, the number of sampling points, and typical landform types. The results show that, compared with triangulated irregular network (TIN), natural neighbor interpolation (NNI), and the Australian National University digital elevation model (ANUDEM) interpolation method, AdpNPR‐DEM has the highest accuracy for all landform types and a better level of robustness. Our method improves the quality of DEM in areas with complex landforms. It could significantly promote the high‐quality production of DEMs, and also promisingly broaden and deepen its applications.
Cysteines have a role in conformation of the UVR8 photoreceptor
Authors: Liao Xinyang , Jenkins Gareth I. 
Published: May 2022

SUMMARYThe UV RESISTANCE LOCUS 8 (UVR8) photoreceptor mediates plant responses to Ultraviolet‐B (UV‐B) wavelengths. The UVR8 dimer dissociates into monomers following UV‐B photoreception, a process accompanied by conformational changes that facilitate interaction of UVR8 with proteins that initiate responses. However, the importance of particular amino acids in maintaining UVR8 conformation and modulating protein interactions is poorly understood. Here we examine the roles of cysteine amino acids C231 and C335 in UVR8 structure and function. UVR8C231S,C335S mutant protein forms dimers and monomerizes similarly to wild‐type UVR8. UVR8C231S,C335S interacts with CONSTITUTIVELY PHOTOMORPHOGENIC 1 (COP1) in plants to initiate photomorphogenic responses to UV‐B, although the interaction is weaker when examined in yeast two‐hybrid assays. Similarly, the interaction of UVR8C231S,C335S with REPRESSOR OF UV‐B PHOTOMORPHOGENESIS (RUP) proteins is weaker in both plants and yeast compared with wild‐type UVR8. Re‐dimerization of UVR8 in plants, which is mediated by RUP proteins, occurs with reduced efficiency in UVR8C231S,C335S. Fluorescence resonance energy transfer analysis indicates that UVR8C231S,C335S has an altered conformation in plants, in that the N‐ and C‐termini appear closer together, which may explain the altered protein interactions.

AbstractBackgroundA national serosurvey of U.S. blood donors conducted in partnership with the Centers for Disease Control and Prevention (CDC) was initiated to estimate the prevalence of SARS‐CoV‐2 infections and vaccinations.MethodsBeginning in July 2020, the Nationwide Blood Donor Seroprevalence Study collaborated with multiple blood collection organizations, testing labs, and leadership from government partners to capture, test, and analyze approximately 150,000 blood donation specimens per month in a repeated, cross‐sectional seroprevalence survey.ResultsA CDC website (https://covid.cdc.gov/covid-data-tracker/#nationwide-blood-donor-seroprevalence) provided stratified, population‐level results to public health professionals and the general public.DiscussionThe study adapted operations as the pandemic evolved, changing specimen flow and testing algorithms, and collecting additional data elements in response to changing policies on universal blood donation screening and administration of SARS‐CoV‐2 spike‐based vaccines. The national serosurvey demonstrated the utility of serosurveillance testing of residual blood donations and highlighted the role of the blood collection industry in public–private partnerships during a public health emergency.

AbstractA 2‐year‐old castrated male Creole Shepherd mixed dog was presented for non‐ambulatory paraparesis of the pelvic limbs. The magnetic resonance imaging and cerebrospinal fluid (CSF) analysis were consistent with meningomyelitis. Positive serology for Ehrlichia canis/Ehrlichia ewingii suggested exposure to a pathogen; qPCR on the serum and the CSF confirmed active infection. Ehrlichial morulae were observed within CSF and peripheral blood polymorphonuclear neutrophils; a species‐specific PCR confirmed E. canis infection. This is an interesting report of E. canis infection in a dog with morulae observed in neutrophils both in the peripheral blood and CSF.

Published: May 2022

AbstractObjectiveTo assess the effect of vocal cordectomy on airflow across equine larynges at different Rakestraw grades of arytenoid abduction using a unidirectional airflow model.Study designEx vivo, repeated measures.Sample populationTwenty cadaveric equine larynges.MethodsThe right arytenoid cartilage was maximally abducted in all larynges. Each larynx was assigned a Rakestraw grade A or B, and the left arytenoid was abducted accordingly. Each larynx was tested under 3 conditions: intact, left vocal cordectomy (LVC), and bilateral vocal cordectomy (BVC). Translaryngeal pressure and airflow were measured, and digital video footage was obtained. Translaryngeal impedance (TLI) was calculated, and the arytenoid left‐to‐right quotient angle (LRQ) and rima glottis cross‐sectional area (CSA) were measured from standardized still images.ResultsVocal cordectomy reduced TLI by 14.5% in LVC in comparison with intact larynges at Rakestraw grade B (P = .014). In Rakestraw grade A position, neither unilateral nor bilateral vocal cordectomy had any effect on TLI. Regardless of Rakestraw allocation, both LVC and BVC increased CSA in comparison with intact larynges (P < .005), with BVC larynges experiencing a greater effect than LVC (P < .0001).ConclusionUsing a unilateral airflow model, LVC improved TLI in larynges where arytenoid position approximated Rakestraw grade B. However, when the arytenoid position approximated Rakestraw grade A, there was no effect on TLI following LVC or BVC.Clinical significanceSurgeons considering a vocal cordectomy should take into account the degree of arytenoid abduction before performing the procedure, as it may not be warranted from a TLI point of view.

Model-Based Transmission Control

Published: May 2022

Abstract
This article presents an overview of model-based transmission control. The transmission is an integral part of the automotive powertrain and connects the engine to the vehicle via the driveline. Just as for the internal combustion engine, traditional transmission control has been conducted with extensive calibrations. This is mainly due to the lack of precise models and low cost sensors that can enable real-time model-based feedback control. However the calibration-based approach is facing more challenges as the recent trend in transmission systems has driven up the time and cost associated with the calibration process. Recently, eight and nine speed transmissions have been introduced. The increasing number of different types of transmissions and the gear ratios can drastically increase the burden for control calibration. This calls for control-oriented model development and model-based control. Transmission control is mainly concerned with the transmission shift scheduling and gear ratio shift control. This shift scheduling determines when to shift and which gear to shift.

ObjectiveTo determine the impact of sodium-dependent glucose type 2 cotransporter inhibitors on the renal function in acute heart failure.MethodsIn a single-centre, controlled, randomised study, patients were prescribed dapagliflozin in addition to standard therapy, or were in receipt of standard therapy. The prespecified outcome was renal function deterioration; the secondary outcomes were the development of resistance to diuretics, weight loss, death during hospitalisation and the rehospitalisation or death for any reason within 30 days following discharge.Results102 patients were included (73.4±11.7 years, 57.8% men). The average left ventricular ejection fraction was 44.9%±14.7%, the average N-terminal prohormone of brain natriuretic peptide (NT-proBNP) was 4706 (1757; 11 244) pg/mL, the average estimated glomerular filtration rate (eGFR) was 51.6±19.5 mL/min. eGFR decreased 48 hours after randomisation in the dapagliflozin group (−4.2 (−11.03; 2.28) mL/min vs 0.3 (−6; 6) mL/min; p=0.04) but did not differ between the groups on discharge (54.71±19.18 mL/min and 58.92±24.65 mL/min; p=0.36). The incidence of worsening renal function did not differ (34.4% vs 15.2%; p=0.07). In the dapagliflozin group, there was less tendency to increase the dose of loop diuretics (14% vs 30%; p=0.048), lower average doses of loop diuretics (78.46±38.95 mg/day vs 102.82±31.26 mg/day; p=0.001) and more significant weight loss (4100 (2950; 5750) g vs 3000 (1380; 4650) g; p=0.02). In-hospital mortality was 7.8% (4(8%) in the dapagliflozin and 4 (7.7%) in the control group (p=0.95). The number of deaths within 30 days following discharge in the dapagliflozin group and in the control group was 9 (19%) and 12 (25%), p=0.55; the number of rehospitalisations was 14 (29%) and 17 (35%), respectively (p=0.51).ConclusionThe use of dapagliflozin was associated with a more pronounced weight loss and less need to increase diuretic therapy without significant deterioration of the renal function. Dapagliflozin did not improve the in-hospital and 30-day prognosis after discharge.Trial registration numberN04778787.

AbstractBlack holes can be inserted in very rich astrophysical environments, such as accretion disks. Although isolated black holes are simple objects in general relativity, their accretion disks may significantly enrich the field configurations of their surroundings. Alternative theories of gravity can lead to novel black hole solutions, which can be represented by small deviations in the metric due to an effective stress-energy tensor. Among the key aspects of the interaction of black holes with their surroundings, stand tidal forces phenomena. We study the tidal forces of spherically symmetric black holes in the presence of effective matter fields, dubbed asdirty black holes. These effective fields can generically represent usual or exotic matter associated to a variety of gravity theories. We show that thisdirtinessleads to characteristic imprints in the tidal forces, which are absent in the case of a black hole surrounded by vacuum. We apply our results to particular cases, such as black holes coupled to linear and nonlinear electrodynamics theories and a Schwarzschild black hole surrounded by a spherical shell.
An improvement of a key exchange protocol relying on polynomial maps
Authors: Suzuki Keita , Nuida Koji 
Published: May 2022

Akiyama et al. [A key exchange protocol relying on polynomial maps, Int. J. Math. Ind. 11 (2019) 195003] proposed a post-quantum key exchange protocol that is based on the hardness of solving a system of multivariate nonlinear polynomial equations but has a design strategy different from ordinary multivariate cryptography. Their protocol has two versions, an original one and a modified one, where the modified one has a trade-off that its security is strengthened while it has nonzero error probability in establishing a common key. In fact, the evaluation in their paper suggests that the probability of failing to establish a common key by the modified protocol with the proposed parameter set is impractically high. In this paper, we improve the success probability of Akiyama et al.’s modified key exchange protocol significantly while keeping the security, by restricting each component of the correct common key from the whole of the coefficient field to its small subset. We give theoretical and experimental evaluations showing that our proposed parameter set for our protocol is expected to achieve both failure probability [Formula: see text] and 128-bit security level.
