Published: July 2024

ABSTRACTAchieving high‐performance aggregation is essential to scaling data‐parallel distributed machine learning (ML) training. Recent research in in‐network computing has shown that offloading the aggregation to the network data plane can accelerate the aggregation process compared to traditional server‐only approaches, reducing the propagation delay and consequently speeding up distributed training. However, the existing literature on in‐network aggregation does not provide ways to deal with slower workers (called stragglers). The presence of stragglers can negatively impact distributed training, increasing the time it takes to complete. In this paper, we present Serene, an in‐network aggregation system capable of circumventing the effects of stragglers. Serene coordinates the ML workers to cooperate with a programmable switch using a hybrid synchronization approach where approaches can be changed dynamically. The synchronization can change dynamically through a control plane API that translates high‐level code into switch rules. Serene switch employs an efficient data structure for managing synchronization and a hot‐swapping mechanism to consistently change from one synchronization strategy to another. We implemented and evaluated a prototype using BMv2 and a Proof‐of‐Concept in a Tofino ASIC. We ran experiments with realistic ML workloads, including a neural network trained for image classification. Our results show that Serene can speed up training by up to 40% in emulation scenarios by reducing drastically the cumulative waiting time compared to a synchronous baseline.

Published: July 2024

AbstractThis article investigates the control problem of switched systems with time‐varying delays under asynchronous switching. By reconstructing the switching rule of local controllers and empolying multiple Lyapunov functionals and integral inequalities, sufficient conditions without the constraint between the switching delay and the dwell time of submodes to solve the control problem are derived. The control gain matrices can be conveniently obtained by the proposed linear search algorithm.

AbstractAimFew studies have reported on the prevalence rate of extra‐articular diseases and on the clinical symptom and temporomandibular joint (TMJ) magnetic resonance imaging (MRI) findings that are seen in these diseases and are not related to genuine temporomandibular joint disorders (TMDs). Therefore, we aimed to determine the prevalence rate and clinical symptom of extra‐articular diseases of the head and neck region that mimic genuine TMDs on 3‐tesla (3T) MRI.MethodsThis study included 100 patients who were clinically diagnosed with TMDs and underwent TMJ MRI. We recorded lesions with abnormal signal intensities in the head and neck region using axial Dixon T2‐weighted imaging (T2WI). The clinical symptoms of the patients and pathology of extra‐articular diseases were determined based on medical records.ResultsThree patients (three males; mean age, 44.3 years) had lesions with abnormal high signal intensity in the head and neck region. All three patients presented with trismus as a clinical symptom. The locations of the lesions were as follows: the left medial and lateral pterygoid muscles, deep lobe of the right parotid gland, and body of the left mandible. Two patients had malignancies.ConclusionAmong the patients who visited the hospital, 3% had extra‐articular diseases and presented with genuine TMD symptom. Trismus may be a key clinical symptom indicating the presence of extra‐articular diseases and need for further clinical or imaging examinations.

AbstractIn the ICD‐11, a new model for the diagnosis of personality disorders is included, consisting of an assessment of the severity of personality impairment as well as an optional evaluation of pathological personality traits. This study aimed to examine the reliability, structural validity, and convergent and discriminant validity of the Norwegian versions of the Personality Disorder Severity ICD‐11 (PDS‐ICD‐11) scale for the assessment of personality disorder severity and the Revised Personality Assessment Questionnaire for ICD‐11 (PAQ‐11R) for the assessment of the ICD‐11 pathological personality traits in a Norwegian community sample. The sample consisted of 295 participants (75.9% female) with a mean age of 30.0 years (SD = 10.7 years). The participants answered the PDS‐ICD‐11, PAQ‐11R, Level of Personality Functioning Scale–Brief Form 2.0 (LPFS‐BF 2.0), and the Personality Inventory for DSM‐5–Brief Form Plus Modified (PID5BF + M). The Norwegian PDS‐ICD‐11 showed good reliability. Support for a unidimensional model and a high convergent correlation with the LPFS‐BF 2.0 was found. The reliability analysis of the Norwegian PAQ‐11R scales yielded mixed findings with suboptimal reliability estimates for the PAQ‐11R detachment, disinhibition, and dissociality scales. Analyzing the structure of the PAQ‐11R items, four factors emerged (negative affectivity, detachment, disinhibition, and anankastia). The PAQ‐11R scales showed good convergent and, overall, adequate discriminant validity with the PID5BF + M scales. The findings support the use of the PDS‐ICD‐11 for assessing severity in the ICD‐11 PD model in Norway. The Norwegian PAQ‐11R appears to be a useful screening tool for the ICD‐11 PD trait domains.
Cellulose acetate synthesized from cold‐sheared cellulose shows improved ability to toughen poly(lactic acid)

Published: July 2024

AbstractCellulose acetate (CA), synthesized by solid–liquid acetylation of low crystalline cellulose (LCCell) obtained by cold shearing in a short time under environmentally benign conditions, effectively enhanced the crystallization of poly(lactic acid) (PLA). The composite of PLA compounded with CA from LCCell exhibited higher crystallinity of PLA and flexural modulus than those from pristine PLA. CAs obtained from crystalline and recrystallized cellulose also improved the mechanical strength of PLA by compounding, but their effects were weaker than that of CA from LCCell. The factor of the effectiveness of CA obtained from LCCell is the higher miscibility with PLA originating from the sufficiently released interchain hydrogen bonds in the cellulose fibrils by cold shearing, which allows the dissolution of macroscopic aggregation of the CA chains in the composite.

Published: July 2024

AbstractPurposeBoth lower urinary tract symptoms (LUTS) and prostate cancer (PCa) are common in elderly men. While LUTS are generally due to a benign etiology, they may provoke an evaluation with prostate‐specific antigen (PSA), which can lead to a cascade of further testing and possible overdiagnosis in patients with competing risks. There is limited patient and provider understanding of the relationship between LUTS and PCa risk, and a lack of clarity in how to evaluate these men to balance appropriate diagnosis of aggressive PCa with avoidance of overdiagnosis.MethodsA literature review was performed using keywords to query the electronic database PubMed. All articles published before November 2023 were screened by title and abstract for articles relevant to our subject.ResultsEpidemiological studies suggest that LUTS and PCa are largely independent in elderly men. The best available tools to assess PCa risk include PSA permutations, novel biomarkers, and imaging, but there are limitations in older men based on lack of validation in the elderly and unclear applicability of traditional definitions of “clinically significant” disease. We present a three‐tiered approach to evaluating these patients.ConclusionElderly men commonly have LUTS as well as a high likelihood of indolent PCa. A systematic and shared decision‐making‐based approach can help to balance objectives of appropriate detection of phenotypically dangerous disease and avoidance of over‐testing and overdiagnosis.

Published: July 2024

AbstractDespite various proposed control schemes for uncertain bilateral teleoperation systems under time delays, optimally restricting the system's overshoot has remained an overlooked issue in this realm. For this aim, we propose two novel control architectures based on robust L1 theory, entitled position‐based adaptive L1 controller and transparent adaptive L1 controller, with the former focusing on position synchronization and the latter concerning system transparency. Since developing L1‐based controllers for nonlinear telerobotic systems encompassing uncertainty and round‐trip delays puts significant theoretical challenges forward, the main contribution of this paper lies in advancing L1 theory within the field of delayed teleoperation control. To formulate the theories, the asymptotic stability of the closed‐loop system for each controller is first proved utilizing the Lyapunov method, followed by transformation, along with the L1 performance criterion, into linear matrix inequalities. Ultimately, the control gains are attained by solving a convex optimization problem. The superiority of the designed controllers over a benchmark transparent controller for teleoperators is demonstrated via simulation. Furthermore, experimental tests on a two‐degrees‐of‐freedom nonlinear telerobotic system validate the efficient performance of the proposed controllers.

Abstract2D native surface oxides formed on low melting temperature metals such as indium and gallium offer unique opportunities for fabricating high‐performance flexible electronics and optoelectronics based on a new class of liquid metal printing (LMP). An inherent property of these Cabrera‐Mott 2D oxides is their suboxide nature (e.g., In2O3−x), which leads high mobility LMP semiconductors to exhibit high electron concentrations (ne > 1019 cm−3) limiting electrostatic control. Binary alloying of the molten precursor can produce doped, ternary metal oxides such as In‐X‐O with enhanced electronic performance and greater bias‐stress stability, though this approach demands a deeper understanding of the native oxides of alloys. This work presents an approach for hypoeutectic rapid LMP of crystalline InGaOx (IGO) at ultralow process temperatures (180 °C) beyond the state of the art to fabricate transistors with 10X steeper subthreshold slope and high mobility (≈18 cm2 Vs−1). Detailed characterization of IGO crystallinity, composition, and morphology, as well as measurements of its electronic density of states (DOS), show the impact of Ga‐doping and reveal the limits of doping induced amorphization from hypoeutectic precursors. The ultralow process temperatures and compatibility with high‐k Al2O3 dielectrics shown here indicate potential for 2D IGO to drive low‐power flexible transparent electronics.

AbstractFlexible all‐solid‐state asymmetric supercapacitors (FAASC) represent a highly promising power sources for wearable electronics. However, their energy density is relatively less as compared to the conventional batteries. Herein, a novel ultra‐high energy density FAASC is developed using nickel–cobalt sulfide (NiCo2S4)/polyaniline (PANI)/manganese dioxide (MnO2) ternary composite on carbon fiber felt (CF) as positive and N, S‐co‐doped carbon nanofibers (CNF)/CF as negative electrode, respectively. Initially, porous δ‐MnO2 nanoworm‐like network is decorated on CF using potentiodynamic method. Subsequently, interconnected PANI nanostructures is grown on the MnO2 via a facile in situ chemical polymerization, followed by the electrodeposition of highly porous NiCo2S4 nanowalls. Benefiting from 3D porous structure of conductive CF and redox active properties of NiCo2S4, PANI and MnO2, FAASC achieved a superior energy storage capacity. Later, high‐performance N, S‐co‐doped CNF/CF negative electrode is synthesized using electropolymerization of PANI nanofibers on CF, followed by the carbonization process. The assembled FAASC exhibits a wide voltage window of 2.2 V and remarkable specific capacitance of 143 F g−1 at a current density of 1 A g−1. The cell further delivers a superb energy density of 71.6 Wh kg−1 at a power density of 492.7 W kg−1, supreme cycle life and remarkable electrochemical stability under mechanical bending.

Published: July 2024

AbstractLow‐energy visible‐light‐activated carbon dots (CDs)‐based afterglow materials are difficult to realize due to the inherent aromatic carbon with high‐energy absorption and the lack of effective regulation. Here, a new strategy for visible‐light‐activated CDs is proposed by combining dual‐confinement and surface‐ionization, which employs NaOH for additional confinement and surface ionization of CDs in a single boric acid (BA) matrix. The comparison experiments show that: i) shifting the excitation from UV‐light to vis‐light is realized by enhancing the low‐energy surface states n→π* transition of the CDs by surface ionization of NaOH. ii) CDs are additionally protected by a more stable Na─O ionic bond after NaOH confinement, resulting in a brighter afterglow. iii) the energy gap (ΔEST) between the lowest singlet and triplet states is gradually shortened as increasing NaOH content, facilitating intersystem crossing, prolonging the lifetime of triplet excitons and efficiency. Further, vis‐light‐excited colorful afterglow powders are fabricated based on Förster Resonant Energy Transfer by combining the fluorescent dye 5‐carboxytetramethylrhodamine. Finally, advanced white‐light‐activated time‐resolved anti‐counterfeiting and intelligent traffic flashing signs are realized. The work may shed new light on the design of low‐energy‐activated afterglow materials and broaden the application scenarios in the daily lives of human society.

ABSTRACTMicroplastics (MPs) and glyphosate‐based herbicides (GBH) are among the most common contaminants in aquatic environments. In Brazilian rivers, both contaminants were found in elevated levels, leading to a high probability of their association, which can alter their individual effects and potentially intensify their toxicity. This study evaluated the isolated and combined effects of polyethylene microplastics (PE‐MPs) and GBH on Oreochromis niloticus using multi‐biomarkers of toxicity. The fish were subjected to a 96‐h exposure period, with concentrations set based either isolated, PE‐MPs group (5 mg L−1), GBH group (5 mg L−1), or in a group of associated contaminants (GAC), PE‐MP + GBH (5 mg L−1 + 5 mg L−1). Toxicity effects were evaluated using biochemical, cytogenetic, hematological, and histopathological biomarkers. We observed change in erythrocyte parameters leading to macrocytic normochromic anemia in GAC. Leukocyte parameters indicate a nonspecific immunosuppression caused by the exposure of associated contaminants, besides the attempts to repair damage caused by PE‐MPs. Histopathological markers indicate damage to tissues exposed to contaminants. Besides, there were morphophysiological adjustments on gills, with proliferation and hypertrophy of mitochondria‐rich cells on GBH and GAC, besides epithelium ruptures, which were mostly present in the exposed groups. Therefore, this study indicates that PE‐MPs and GBHs present toxic effects in O. niloticus with the used concentrations, intensified by the association of contaminants. Thus, multi‐biomarkers were useful key to verify toxicity, providing data to the investigation of high levels of contaminant's mixture toxicity present in aquatic environments.

AbstractBackgroundInfectious bursal disease (IBD) is a viral infectious disease that affects young chicks. A cross‐sectional study was conducted from October 2020 to June 2021 to determine seroprevalence and associated risk factors of IBD on backyard chickens of purposively selected three districts of Buno Bedelle Zone, Southwestern Ethiopia.MethodsThe study was carried out via a collection of serum samples, questionnaire surveys, and a total of 768 serum samples were collected from randomly selected backyard chickens of the study areas and examined for the presence of IBD virus. These serum samples were processed by using an indirect enzyme‐linked immunosorbent assay test procedure in laboratories. SPSS version 20 was used for data analysis and descriptive statics techniques were used.ResultsOut of a total serum samples collected, 361 of them were found positive for the disease with an overall seroprevalence of 47%. Different seroprevalence rates of IBD with 55.9%, 43.3% and 41.2% were recorded in Didessa, Chora and Gechi districts, respectively. The result indicated that there was statistically significant difference (p < 0.05) of the disease among the three districts. Among the nine Peasant Associations (PAs) observed for seroprevalence of IBD, highest (62.9%) and lowest (34.20%) seroprevalence of the disease was recorded in Yembero and Shengela PAs, respectively. However, IBD was statistically significant in only Shengela PA of Chora district (p = 0.04, OR = 1.93 and 95% CI 1.04–3.58) and Seko PA of Gechi district (p = 0.05, OR = 1.79 and 95% CI 1.01–3.16). Even though sex, breed, age, source and management‐based seroprevalence was observed in the present study, the result indicated that there was only statistical significant difference (p = 0.004, OR = 0.62 and 95% CI 0.45–0.86) seen in which higher seroprevalence of IBD was determined in exotic (50.3%) than in local (38.6%) chickens breeds of the study areas.ConclusionGenerally, higher seroprevalence of IBD in the present study indicates a widely distribution of the disease and one of the potential threats for poultry production in the study areas. So, chicken vaccination and improved management system should be warranted in order to control the disease effectively.

AbstractBackgroundAmong the large animals, the heart of sheep is functionally and structurally very similar to the human heart. In research, sheep are used as an animal model to study the process of cardiac disease pathogenesis and treatment. Therefore, determining the normal values of the heart structures of sheep with echocardiography is of particular emphasis. The purpose of the present research is to define the normal echocardiography values of heart in Iranian Shall breed sheep.Materials and methodsIn 20 healthy Iranian Shall male sheep weighing 30–35 kg and aged 4–6 months, standing echocardiography was done from the right parasternal approach concentrated on the 3rd to 5th intercostal spaces by 2.5–5 MHz phased array transducer in the longitudinal and transverse views by B‐mode, M‐mode and Doppler systems. In M‐mode echocardiographic, the parameters of interventricular septal, left ventricular internal diameter, left ventricular free wall, right ventricular free wall and right ventricular internal diameter in diastole and systole as well as end point septal separation, ejection fraction (EF) slope, aortic root diameter, left atrial appendage, left atrial diameter/aortic valve diameter, left ventricular ejection time, fractional shortening, end‐diastolic volume, end‐systolic volume, EF, stroke volume and cardiac output and in pulsed‐wave spectral Doppler echocardiographic, the parameters of mitral valve maximum velocity (Vmax), mitral valve mean velocity (Vmean), mitral valve maximum pressure gradient (PGmax), mitral valve mean pressure gradient (PGmean), mitral valve velocity time integral (VTI), mitral valve E‐wave (MV‐E), MV‐E pressure gradient, mitral valve A‐wave (MV‐A), MV‐A pressure gradient, aortic Vmax, aortic valve Vmean, aortic valve PGmax, aortic valve PGmean, aortic valve VTI, left ventricular outflow tract (LVOT)‐Vmax, LVOT‐Vmean were measured.ResultsAll the sheep in this study were healthy and had no signs of heart disease. In this study, the parameters of M‐mode and spectral Doppler echocardiographic were assessed and recognized in Iranian Shall sheep. The results demonstrated the parameters of echocardiographic could be dependably determined in Shall sheep which, established normal reference values for these parameters and left ventricular function indices in healthy Shall sheep. These results can be beneficial in appropriate imagination, recognition and measuring cardiac structures.ConclusionThis study can be exerted as a reference for the assessment and diagnosis of heart diseases in sheep medicine and human cardiovascular research in sheep experimental models.
