A multithreaded CUDA and OpenMP based power‐aware programming framework for multi‐node GPU systems
Authors: Czarnul Paweł 
Published: August 2023

SummaryIn the article, we have proposed a framework that allows programming a parallel application for a multi‐node system, with one or more graphical processing units (GPUs) per node, using an OpenMP+extended CUDA API. OpenMP is used for launching threads responsible for management of particular GPUs and extended CUDA calls allow to transfer data and launch kernels on local and remote GPUs. The framework hides inter‐node MPI communication from the programmer. For optimization, the implementation takes advantage of the MPI_THREAD_MULTIPLE mode allowing: multiple threads handling distinct GPUs as well as overlapping communication and computations transparently using multiple CUDA streams. The solution allows data parallelization across available GPUs in order to minimize execution time and supports a power‐aware mode in which GPUs are automatically selected for computations using a greedy approach in order not to exceed an imposed power limit. We have implemented and benchmarked three parallel applications including: finding the largest divisors; verification of the Collatz conjecture; finding patterns in vectors. These were tested on three various systems: a GPU cluster with 16 nodes, each with NVIDIA GTX 1060 GPU; a powerful 2‐node system—one node with 8 NVIDIA Quadro RTX 6000 GPUs, the second with 4 NVIDIA Quadro RTX 5000 GPUs; a heterogeneous environment with one node with 2 NVIDIA RTX 2080 and 2 nodes with NVIDIA GTX 1060 GPUs. We demonstrated effectiveness of the framework through execution times versus power caps within ranges of 100–1400 W, 250–3000 W, and 125–600 W for these systems respectively as well as gains from using two versus one CUDA streams per GPU. Finally, we have shown that for the testbed applications the solution allows to obtain high speed‐ups between 89.3% and 97.4% of the theoretically assessed ideal ones, for 16 nodes and 2 CUDA streams, demonstrating very good parallel efficiency.

AbstractBackgroundBouldering psychotherapy (BPT) for depression has proven effective, but nothing is known about its potential predictors of response. This study should identify predictors of response to BPT, cognitive behavioural therapy (CBT) and an active control (home‐based exercise programme; EP) using a literature‐based model.MethodsIn a multicentre randomised controlled trial, 233 outpatients were assigned to BPT, CBT or EP. Response (reduction of at least 46% on the Montgomery–Åsberg Depression Rating Scale [MADRS]) and remission (≤7 MADRS points) were defined as suggested by the literature. Predictors of response were identified twofold: (1) univariate analyses followed by logistic regression analyses in each group with all predictors yielding a univariate p‐value <.20 and (2) a backward regression analysis with all potential predictors. Only variables that emerged as predictors in both types of analyses were interpreted.ResultsThere was a significantly greater proportion of responders (p = .035) in the BPT than in the EP. The chance of response in the BPT was higher for patients with a higher health‐related quality of life. In the EP, response was higher for patients with lower interpersonal sensitivity, suffering from their first episode and living with a partner.ConclusionsResponse rates in BPT are similar to or even higher than in other outpatient psychotherapy group therapies. BPT and CBT are suitable for a wide range of patients, but patients with higher functionality could start with psychoeducation and exercise.
Gain Enhancement of Composite Photonic Crystal Microstrip Patch Antenna Inspired by Maxwell Garnett Model for C‐Band, X‐Band and Ku Band Applications
Authors: Mercy P. Arockia Michael , Wilson K. S. Joseph 
Published: August 2023

AbstractThe latest developments in communication systems require an economical, light‐weight, compact size, and excellent performance in microstrip patch antennas in order to meet the requirements of the upcoming implementation. The optical, electrical, and physical properties of different materials have an impact on the design of antennas. An innovative composite photonic crystal microstrip patch antenna with outstanding gain has been developed. For composites of fumed silica embedded in RT‐Duroid dielectric material, the effective permittivity is calculated using the Maxwell‐Garnett model. The performance of composite antennas for different volume fractions and various dielectric substrate thicknesses is studied. The resonance frequencies of composites also shift from the X‐band to the C‐band with an increase in volume concentration, which is suitable for wireless communication systems. This investigation provides a perspective on how composite substrates can represent a communication revolution by providing an alternative to substrates that are readily accessible commercially in situations when the material qualities are insufficient. The photonic crystal composite antenna records the highest gain of 13.89 dB with the coverage of C‐band, X‐band, and Ku‐band, whereas the composite antenna reaches the best gain of 10 dB with the coverage of C‐band and X‐band.
Multi‐tiered dispute resolution clauses in engineering contracts: A Jordanian legal perspective

Published: August 2023

AbstractThis study delves into the intricacies of the multi‐tier dispute resolution clause in engineering contracts, particularly within the Jordanian legal system. The multi‐tier dispute resolution clause has evolved from a traditional arbitration clause into a more comprehensive approach, reflecting the complexities of modern contractual relationships. The study employs a doctrinal or library‐based methodology involving a comprehensive review of relevant legal texts, statutes, regulations, and case law. The multi‐tier dispute resolution clause is defined as a contractual clause that stipulates the existence of different stages, each involving separate procedures, to address disputes and seek to resolve them. The study also examines the mandatory nature of the multi‐tier dispute resolution clause and the procedural defense based on an arbitration clause. The study concludes that following the sequence outlined, the multi‐tier dispute resolution clause should be binding. This necessitates the Jordanian legislator's intervention to establish a legislative framework that empowers decisions made by the Dispute Adjudication Board (DAB) or Dispute Avoidance/Adjudication Board (DAAB) to achieve the goals of multi‐tiered dispute resolution clause. It also calls for an amendment to Article (109) of the Civil Procedure Law, allowing procedural defense based on the Multi‐Tiered Dispute Resolution Clause, not limiting it to the arbitration clause, even if arbitration is not one of its tiers. This power should also extend to amicable settlements to ensure the proper implementation of the steps under the multi‐tiered dispute resolution clause.

AbstractCo‐inoculation of soybean with plant growth‐promoting microorganisms has the potential to increase yield, and the Amazon is a biome rich in these beneficial microorganisms. Soybean is the most important grain crop in Brazil and is highly benefited by inoculation with Bradyrhizobium spp. strains, both of which represent exotic symbiotic partners. The objective of this study was to evaluate the effects of soybean co‐inoculation with Amazonian strains of Trichoderma asperellum and Bacillus amyloliquefaciens. Greenhouse and field experiments were conducted during the 2020 and 2021 crop seasons in Brazil, respectively. The experimental design was completely randomized in the greenhouse, and randomized blocks were used in the field, both with 3 × 2 factorial schemes. Standard inoculation with Bradyrhizobium and co‐inoculation with T. asperellum and B. amyloliquefaciens was considered the first factor, and the second factor was represented by phosphate fertilization (0 and 100 kg ha−1 of P2O5). The root system volumes were 25% and 17% higher than those of the standard inoculation with T. asperellum and B. amyloliquefaciens, respectively. In 2020, co‐inoculation with T. asperellum increased yield by 15%, plant height by 27%, and net profit by up to 121 USD compared with standard inoculation. In 2021, co‐inoculation with T. asperellum and B. amyloliquefaciens resulted in increases in several growth parameters compared to those with standard inoculation, including 7% and 13% greater yields, and 159 USD and 309 USD increases in net profit, respectively. Our results indicate the possibility of expanding soybean co‐inoculation with local strains of Bacillus and Trichoderma, with benefits for productivity and profitability.
Two modes of contact‐time reduction in the impact of particle‐coated droplets on superhydrophobic surfaces

Published: August 2023

AbstractReducing the contact time during droplet impact is essential for many scientific and industrial applications, such as self‐cleaning, anti‐icing, heat transfer, and condensation. This paper reports contact‐time reduction by coating droplets with micro–nano hydrophobic particles. Such particle‐coated droplets are known as liquid marbles (LM). LM impact on superhydrophobic surfaces reveals two different modes of contact‐time reduction. For lower impact energies, the reduced adhesion of LM with the surface is responsible for a reduction of up to 21%. Contact‐time reduction in this regime is found to be independent of particle size but dependent on the solid fraction of LM. However, a fragmentation‐based contact‐time reduction is observed for larger particle sizes and higher impact energies. Here, the reduction is as high as 65%. Such fragmentation occurs because the spreading LM lamella breaks when its thickness becomes similar to particle dimensions. Our findings reveal the potential of LM as a novel approach to reduce contact time during droplet impact, with implications for various scientific and industrial applications.

ABSTRACTAimChronic obstructive pulmonary disease (COPD) is common in heart failure with a mildly reduced or preserved ejection fraction (HFmrEF/HFpEF) and is associated with worse outcomes. In a pre‐specified analysis of DELIVER, we investigated the relationship between COPD status and outcomes, and the efficacy and safety of dapagliflozin, compared with placebo, according to COPD status.Methods and resultsPatients with severe pulmonary disease (including COPD) were excluded from the trial. The primary outcome was a composite of cardiovascular death or worsening heart failure. Of the 6261 patients with data on baseline COPD status, 694 (11.1%) had a known history of this condition. The risk of the primary endpoint was higher in patients with mild‐to‐moderate COPD compared with those without COPD (adjusted hazard ratio [HR] 1.28, 95% confidence interval [CI] 1.08–1.51). The benefit of dapagliflozin on the primary outcome was consistent irrespective of COPD status (no COPD: HR 0.82 [95% CI 0.72–0.93]; COPD: HR 0.82 [95% CI 0.62–1.10]; pinteraction = 0.98). Consistent effects were observed for heart failure, cardiovascular, and all‐cause hospitalization, and deaths, and composites of these. Dapagliflozin, as compared with placebo, improved the Kansas City Cardiomyopathy Questionnaire scores from baseline to 8 months to a similar extent in patients with and without mild‐to‐moderate COPD (pinteraction ≥ 0.63). Adverse events and treatment discontinuation were not more frequent with dapagliflozin than with placebo irrespective of COPD status.ConclusionsMild‐to‐moderate COPD is common in patients with HFmrEF/HFpEF and is associated with worse outcomes. The beneficial effects of dapagliflozin compared with placebo on clinical events and symptoms were consistent, regardless of COPD status.Clinical Trial Registration: ClinicalTrials.gov NCT03619213.

Published: August 2023

AbstractHerein, an efficient methodology for the homogeneous manganese‐catalysed transfer hydrogenation of N‐heterocycles by using ammonia‐borane as a hydrogen source under mild reaction conditions is reported. Good to excellent isolated yields are achieved by applying a PNP manganese pincer complex. In the reaction, 1,2‐dihydroquinoline is detected as intermediate by NMR spectra analysis and deuterium labelling experiment. The catalytic reaction likely proceeded by an outer‐sphere pathway based on the bifunctional pincer complex.

Published: August 2023

AbstractIonovoltaics is a breakthrough concept in energy conversion that harnesses water motion with ion dynamics to generate electrical energy. This phenomenon is based on the interaction between the nanoscopic ionic behavior at the solid–liquid interface and the flow of electrons in a semiconductor electrode. Ionovoltaic research aims to present the most rational and convincing mechanism for the much‐debated principle of energy conversion by water motion through a deeper understanding of solid–liquid interfacial phenomena and to discuss the potential to transform related fields through the development of enabling technologies such as novel energy harvesters, interfacial analysis tools, and bio/chemical sensors. Furthermore, efforts to develop high‐efficiency ionovoltaic device powered by small water droplets indicate a potential contribution to the advancement of green energy systems that complement solar and wind power generation and address environmental pollution and energy shortages. This review paper explores the evolution of energy harvesting technologies using water motion, with a particular focus on ionovoltaics as an emerging field. By establishing the fundamentals, this study investigates solid–liquid interfaces, semiconductor properties, and natural water motion‐driven ionovoltaic phenomena and also highlights that extensive research on complex ion/interface phenomena can have practical applications in diverse industrial fields.image
Toward multivariate fragility functions for seismic damage and loss estimation of high‐rise buildings
Authors: Kourehpaz Pouria , Molina Hutt Carlos , Lallemant David 
Published: August 2023

AbstractData‐driven models for seismic damage and loss assessment of buildings have become more common in recent years due to the availability of large repositories of recorded and synthetic ground motions coupled with structural response simulation data. This paper explores the benefits of using bivariate and multivariate fragility functions to estimate earthquake‐induced damage and economic loss in high‐rise buildings. The dataset used in this study encompasses 15,000 simulations of modern high‐rise reinforced concrete shear wall buildings ranging from eight to 24 stories which are subjected to ground motion records at five different intensity levels. The proposed functions are conditioned on average spectral accelerations and ground motion significant duration. The results indicate that bivariate fragility functions improve damage state prediction success (Brier score) by 16%, and multivariate fragility functions by 24% relative to conventional univariate functions (standard of practice). To develop multivariate functions, nominal and ordinal probit regression models are fit to the dataset. While both models yield satisfactory predictive performance, ordinal functions can lead to a 15% reduction in misclassified collapse instances, that is, the minority class. Univariate functions tend to overestimate seismic losses at lower intensity levels while underestimating them at higher intensities. These loss estimates are significantly improved when bivariate or multivariate building fragility functions are used. Given the increase in the use of physics‐based ground motion simulations and/or multi‐variate ground motion models, from which multiple intensity measures can be extracted, a shift toward a more complex representation of fragility functions, for example, multivariate curves, is necessary and inevitable. The proposed functions are used to evaluate the performance of a portfolio of modern high‐rise reinforced concrete shear wall buildings at four sites across the Seattle, Washington metropolitan area under a potential magnitude‐9 Cascadia subduction zone earthquake scenario. The results indicate that the proposed functions can be beneficial in enhancing damage state predictions and loss estimates at a regional scale.

AbstractThe benefits of fermented milk have been known to mankind since the ancient days of civilization. The important role of fermented milk in human nutrition has been well documented through the ages, from the original unpredictable souring of milk caused by the microorganisms inherent in milk to modern microbiological processes, leading to fermented milk with the greater nutritional value produced under controlled conditions. The bioactive peptides synthesized by the microbial degradation of proteins in fermented milk and the addition of supplements, such as probiotics and prebiotics endow them with various physiological functions, including the regulation of the gut microbiota, cholesterol lowering, and immunomodulation, making them potential functional foods that are notable in healthy diets. Here, we summarized the development of fermented milk into four stages and also summarized their impact on health and diseases during different developmental stages. In addition, we described the characteristics and limitations of fermented milk in different eras. Accordingly, we integrated the future trends in the development of fermented milk as functional foods. It is hoped that the efforts to develop the potential of fermented milk as functional foods will help manage the health risks faced by many countries.

Published: August 2023

AbstractIn this work, fundamental material properties of compounds in the system (La,Pr)2(Ni,Co)O4+δ as well as their performance as air electrodes in solid oxide electrolysis cells were investigated. Nickelates co‐doped with Pr and Co were characterized on a material basis by means of X‐ray diffraction and thermogravimetry. Conductivity and conductivity relaxation measurements were performed in order to obtain the electronic conductivity as well as the chemical surface exchange coefficient and the chemical diffusion coefficient of oxygen as a function of temperature and oxygen partial pressure. These parameters can be regarded as the most essential properties at the material level required to assess the suitability of mixed ionic‐electronic conducting ceramics for application as air electrode in solid oxide cells. The electrode performance of the materials was then tested on fuel electrode‐supported button cells at 800°C. The electrodes were applied by screen‐printing and the effect of varying the Pr‐content and Co‐content of the electrode powder was investigated. Cell tests were performed by means of current‐voltage measurements in electrolysis mode. While no significant impact of Pr‐doping on the investigated material properties was observed, the electrode performance of Pr‐containing materials was significantly better than for the Pr‐free compound, which has been discussed in detail.

AbstractCalcified chondroid mesenchymal neoplasms represent a distinct, and recently recognized, spectrum of tumors. To date most cases have been reported to be characterized by FN1 gene fusions involving multiple potential tyrosine kinase partners. Following incidental identification of a tumor morphologically corresponding to calcified chondroid mesenchymal neoplasm, but with a PDGFRA::USP8 gene fusion, we undertook a retrospective review to identify and characterize additional such cases. A total of four tumors were identified. Each was multilobulated and composed of polygonal‐epithelioid‐stellate cells with a background of chondroid matrix containing distinctive patterns of calcification. Targeted RNA sequencing revealed an identical PDGFRA (exon 22)::USP8 (exon 5) gene fusion in each case. Subsequent immunohistochemical staining confirmed the presence of PDGFRα overexpression. In summary, we report a series of four tumors within the morphologic spectrum of calcified chondroid mesenchymal neoplasms. In contrast to prior reports, these tumors harbored a novel PDGFRA::USP8 gene fusion, rather than FN1 rearrangement. Our findings expand the molecular diversity of these neoplasms, and suggest they are united through activation of protein kinases.
