Published: April 2024

A substantial level of significance has been placed on renewable energy systems, especially photovoltaic (PV) systems, given the urgent global apprehensions regarding climate change and the need to cut carbon emissions. One of the main concerns in the field of PV is the ability to track power effectively over a range of factors. In the context of solar power extraction, this research paper performs a thorough comparative examination of ten controllers, including both conventional maximum power point tracking (MPPT) controllers and artificial intelligence (AI) controllers. Various factors, such as voltage, current, power, weather dependence, cost, complexity, response time, periodic tuning, stability, partial shading, and accuracy, are all intended to be evaluated by the study. It is aimed to provide insight into how well each controller performs in various circumstances by carefully examining these broad parameters. The main goal is to identify and recommend the best controller based on their performance. It is notified that, conventional techniques like INC, P&O, INC-PSO, P&O-PSO, achieved accuracies of 94.3, 97.6, 98.4, 99.6 respectively while AI based techniques Fuzzy-PSO, ANN, ANFIS, ANN-PSO, PSO, and FLC achieved accuracies of 98.6, 98, 98.6, 98.8, 98.2, 98 respectively. The results of this study add significantly to our knowledge of the applicability and effectiveness of both AI and traditional MPPT controllers, which will help the solar industry make well-informed choices when implementing solar energy systems.

Deciphering past climate variability in the Western Pacific Warm Pool (WPWP), the Earth’s largest heat and moisture centre, is vital for understanding the global climate system. Nevertheless, its long-term evolution remains controversial, largely due to ambiguities in existing proxy interpretations and discrepancies between records. Here, we present a weathering and erosion reconstruction from the WPWP spanning the last 140,000 years, based on the mineralogy and geochemistry of a sediment core from offshore of northern New Guinea. The paleo-weathering reconstruction is consistent with the simulated precipitation evolution on nearby islands, thereby suggesting a close coupling between climate variability and island weathering in a tropical setting. In addition, our combined data-model interpretation of WPWP climate history shows many similarities to the East Asian Summer Monsoon (EASM) variability over orbital timescales. Overall, our study highlights the critical role of precession-paced interhemispheric energy redistribution, via the West Pacific meridional sea-surface pressure gradient, in linking orbital-scale WPWP climate and EASM variability.

The ability to respond to varying environments is crucial for sessile organisms such as plants. The amphibious plant Rorippa aquatica exhibits a striking type of phenotypic plasticity known as heterophylly, a phenomenon in which leaf form is altered in response to environmental factors. However, the underlying molecular mechanisms of heterophylly are yet to be fully understood. To uncover the genetic basis and analyze the evolutionary processes driving heterophylly in R. aquatica, we assembled the chromosome-level genome of the species. Comparative chromosome painting and chromosomal genomics revealed that allopolyploidization and subsequent post-polyploid descending dysploidy occurred during the speciation of R. aquatica. Based on the obtained genomic data, the transcriptome analyses revealed that ethylene signaling plays a central role in regulating heterophylly under submerged conditions, with blue light signaling acting as an attenuator of ethylene signal. The assembled R. aquatica reference genome provides insights into the molecular mechanisms and evolution of heterophylly.
Longitudinal microstructural changes in 18 amygdala nuclei resonate with cortical circuits and phenomics

Published: April 2024

The amygdala nuclei modulate distributed neural circuits that most likely evolved to respond to environmental threats and opportunities. So far, the specific role of unique amygdala nuclei in the context processing of salient environmental cues lacks adequate characterization across neural systems and over time. Here, we present amygdala nuclei morphometry and behavioral findings from longitudinal population data (>1400 subjects, age range 40-69 years, sampled 2-3 years apart): the UK Biobank offers exceptionally rich phenotyping along with brain morphology scans. This allows us to quantify how 18 microanatomical amygdala subregions undergo plastic changes in tandem with coupled neural systems and delineating their associated phenome-wide profiles. In the context of population change, the basal, lateral, accessory basal, and paralaminar nuclei change in lockstep with the prefrontal cortex, a region that subserves planning and decision-making. The central, medial and cortical nuclei are structurally coupled with the insular and anterior-cingulate nodes of the salience network, in addition to the MT/V5, basal ganglia, and putamen, areas proposed to represent internal bodily states and mediate attention to environmental cues. The central nucleus and anterior amygdaloid area are longitudinally tied with the inferior parietal lobule, known for a role in bodily awareness and social attention. These population-level amygdala-brain plasticity regimes in turn are linked with unique collections of phenotypes, ranging from social status and employment to sleep habits and risk taking. The obtained structural plasticity findings motivate hypotheses about the specific functions of distinct amygdala nuclei in humans.
Emergency policies are not enough to resolve Amazonia’s fire crises

Published: April 2024

The fire crises in the Amazon continues to increase the risk of large-scale forest dieback, threatening regional biodiversity and global climate. This issue gained international attention in 2019 when fires in the Brazilian Amazon led to a fire ban imposition. Despite the uncertainty of its impact, the fire ban was reenacted in subsequent years. Here we assess the effectiveness of each fire ban by comparing observed fire counts with climate-driven predictions of fire for 2019–2021. While the 2019 ban likely reduced the number of fires to expected levels, it was largely ineffective in the years that followed. Four years later in 2023 under a different political dynamic, the Brazilian Amazon faced another fire crisis. Resolving this recurrent issue requires interventions that target the underlying causes of fire and extend beyond emergency measures, including long-term strategies focused on landscape management, public awareness and education, and engagement with local communities and stakeholders.

Natural killer (NK) cells are critical to the innate immune system, as they recognize antigens without prior sensitization, and contribute to the control and clearance of viral infections and cancer. However, a significant proportion of NK cells in mice and humans do not express classical inhibitory receptors during their education process and are rendered naturally “anergic”, i.e., exhibiting reduced effector functions. The molecular events leading to NK cell anergy as well as their relation to those underlying NK cell exhaustion that arises from overstimulation in chronic conditions, remain unknown. Here, we characterize the “anergic” phenotype and demonstrate functional, transcriptional, and phenotypic similarities to the “exhausted” state in tumor-infiltrating NK cells. Furthermore, we identify zinc finger transcription factor Egr2 and diacylglycerol kinase DGKα as common negative regulators controlling NK cell dysfunction. Finally, experiments in a 3D organotypic spheroid culture model and an in vivo tumor model suggest that a nanoparticle-based delivery platform can reprogram these dysfunctional natural killer cell populations in their native microenvironment. This approach may become clinically relevant for the development of novel anti-tumor immunotherapeutic strategies.

The torsion of stellar streams and the overall shape of galactic gravity’s source
Authors: Bariego-Quintana Adriana , Llanes-Estrada Felipe J.
Published: April 2024

Context. Flat rotation curves, v(r), are naturally explained by elongated (prolate) dark matter (DM) distributions, and we have provided competitive fits to the SPARC database. To further probe the geometry of the halo, or the equivalent source of gravity in other formulations, one needs observables outside the galactic plane. Stellar streams, poetically analogous to airplane contrails, but caused by tidal dispersion of massive substructures such as satellite dwarf galaxies, would lie on their own plane (consistently with angular momentum conservation) should the DM-halo gravitational field be spherically symmetric. Tracks resembling entire orbits are seldom available because their periods are commensurable with Hubble time, with streams often presenting themselves as short segments.

Aims. Therefore, we aim to establish stellar stream torsion, a local observable that measures the deviation from planarity in differential curve geometry, as a diagnostic providing sensitivity to aspherical DM distributions and ensuring the use of even relatively short streams.

Methods. We performed small-scale simulations of tidally distorted star clusters to check that indeed a central force center produces negligible torsion, while distorted halos can generate it. Turning to observational data, we identified among the known streams those that are at the largest distance from the Galactic center, and that are likely not affected by the Magellanic clouds, as the most promising for the study, and by means of polynomial fits we extracted their differential torsion.

Results. We find that the torsion of the few known streams that should be sensitive to most of the Milky Way’s DM halo is much larger than expected for a central spherical bulb alone. This is consistent with the nonsphericity of the halo.

Conclusions. Future studies of stellar stream torsion with larger samples and further out of the galactic plane should be able to extract the ellipticity of the halo to see whether it is just a slight distortion of a spherical shape or whether it rather resembles a more elongated cigar.
Frozen Gaussian sampling for scalar wave equations
Authors: Chai Lihui , Feng Ye , Zhou Zhennan
Published: April 2024

In this article, we introduce the frozen Gaussian sampling (FGS) algorithm to solve the scalar wave equation in the high-frequency regime. The FGS algorithm is a Monte Carlo sampling strategy based on the frozen Gaussian approximation, which greatly reduces the computation workload in wave propagation and reconstruction. In this work, we propose feasible and detailed procedures to implement the FGS algorithm to approximate scalar wave equations with Gaussian and WKB initial conditions respectively. For both initial data cases, we rigorously analyze the error of applying this algorithm to wave equations of dimensionality d ≥ 3. In Gaussian initial data cases, we prove that the sampling error due to the Monte Carlo method is independent of the typical wave number. We also derive a quantitative bound of the sampling error in WKB initial data cases. Finally, we validate the performance of the FGS and the theoretical estimates about the sampling error through various numerical examples, which include using the FGS to solve wave equations with both Gaussian and WKB initial data of dimensionality d = 1, 2, and 3.

The Purposiveness Principle in Translation Evaluation
Authors: Liu Biao , Deng Yunhua
Published: April 2024

In recent years, the evaluation of translation quality has been widely commented upon in the domestic translation community, with numerous theoretical achievements. However, the author holds that rather than theory, it should be more of practice, in which the practical purposes of translation are involved. The purposes can be roughly classified into two: content-oriented translation and translation for overall appreciation. Different translation purposes should have different evaluation characteristics. In general, there are unified standards for the former; but for the latter, there appear widely accepted distinctions of merits and demerits, and also being complex and not absolutized. This paper, in the light of the purposive evaluation principle, typically discusses the respective evaluation in practice via translation examples.

Authors: Lv Fang
Published: April 2024

With the continuous development and improvement of the social system and structure, the scope of functions of colleges and universities, as market subjects, in participating in market activities continues to expand, and the logos of colleges and universities, as intangible assets of colleges and universities, can be transformed into tangible assets in market activities, and the economic value generated by them has brought considerable benefits to many speculators. The ensuing intellectual property rights dispute about the college logo is becoming more and more fierce. The Outline for Building a strong Intellectual Property Country (2021-2035) clearly proposes to strengthen the construction of an intellectual property protection system, which also provides a reference direction and expected construction for intellectual property protection in universities. This paper will make a simple analysis of the infringement of college logos through case analysis and literature review, and put forward corresponding objective and feasible solutions.

Published: April 2024

Die CD30-positiven primär kutanen lymphoproliferativen Erkrankungen stellen nach der Mycosis fungoides die zweithäufigste Form der kutanen T-Zell-Lymphome dar. Diese Gruppe umfasst die lymphomatoide Papulose (LyP), das primär kutane anaplastische großzellige Lymphom (pcALCL) und Borderline-Läsionen.

Therapeutisch findet bei lokalisierten Läsionen eine topische oder intraläsionale Steroidgabe Anwendung.

Bei disseminiertem Befund kommen u.a. Methotrexat, PUVA oder Brentuximab-Vedotin therapeutisch in Betracht.

Wir stellen hier eine 60-jährige Patientin vor, deren Klinik die Heterogenität dieser Erkrankungen und einen wechselhaften Verlauf über nahezu 3 Jahre zeigt.
Parents’ financial socialization or socioeconomic characteristics: which has more influence on Gen-Z’s financial wellbeing?
Authors: Abdul Ghafoor Khalid , Akhtar Muhammad
Published: April 2024

This research aims to explore the effectiveness of various approaches for promoting financial wellbeing among Gen-Z, with a particular focus on the parental role in shaping financial attitudes and behavior, using the theoretical lens of family financial socialization theory. The study utilized a mixed-methods approach to obtain in-depth findings on parental financial socialization and parental socioeconomic characteristics for Gen-Zs’ financial wellbeing. The qualitative findings revealed that parents use different strategies to financially socialize children by involving them in savings, financial decisions, and household and personal finances. Furthermore, it is found that parents are more inclined to teach daughters than sons about finances because of the expectations that females handle the household finances. Likewise, quantitative findings revealed that the father’s education level negatively influences Gen-Z’s financial attitude. This study strengthens the concept of family socialization and establishes a ground to explore potential mechanisms of action and implications for future research and practice.
Acoustohydrodynamic micromixers: Basic mixing principles, programmable mixing prospectives, and biomedical applications
Authors: Bai Chenhao , Tang Xiaoqing , Li Yuyang , Arai Tatsuo , Huang Qiang , Liu Xiaoming
Published: April 2024

Acoustohydrodynamic micromixers offer excellent mixing efficiency, cost-effectiveness, and flexible controllability compared with conventional micromixers. There are two mechanisms in acoustic micromixers: indirect influence by induced streamlines, exemplified by sharp-edge micromixers, and direct influence by acoustic waves, represented by surface acoustic wave micromixers. The former utilizes sharp-edge structures, while the latter employs acoustic wave action to affect both the fluid and its particles. However, traditional micromixers with acoustic bubbles achieve significant mixing performance and numerous programmable mixing platforms provide excellent solutions with wide applicability. This review offers a comprehensive overview of various micromixers, elucidates their underlying principles, and explores their biomedical applications. In addition, advanced programmable micromixing with impressive versatility, convenience, and ability of cross-scale operations is introduced in detail. We believe this review will benefit the researchers in the biomedical field to know the micromixers and find a suitable micromixing method for their various applications.
Fractional-order acoustic diffraction rings: A nonlocal computational framework for scattering surface-launched waves
Authors: Buonocore Salvatore , Sen Mihir
Published: April 2024

Several recent studies showed that nonlocal metasurfaces have great potential for guiding and exploiting nonlocal acoustic and electromagnetic phenomena. In this work, we provide a generalized description of the potentialities of acoustic nonlocal metasurfaces using a fractional-order hybrid-waves framework (i.e., a mixture of surface phonon polaritons and quasi-cylindrical waves). We provide a general investigation into the emergence of nonlocal resonant dynamics (resulting, for example, from multiple scattering, wave-field attenuation, and local enhancement) and, in particular, the occurrence of Wood-like anomalies due to bounded modes within the acoustic metasurface. The occurrence and transition between these phenomena are investigated by computational results obtained via a fractional-order hybrid-waves framework. The intrinsic capabilities of the proposed mathematical framework offer a novel route for guiding and exploiting a plethora of hybrid-wave transport effects with important implications from material characterization (e.g., Raman scattering) to bio-oriented applications.
