Topology change and heterotic flux vacua
Authors: Israël Dan , Melnikov Ilarion V. , Minasian Ruben , Proto Yann 
Published: July 2024

Abstract
We investigate the interrelation between topology and Narain T-duality of heterotic flux vacua. We present evidence that all 5 and 4-dimensional Minkowski space heterotic flux backgrounds with 8 supercharges have a locus in the moduli space with a T-dual description in terms of a compactification on the product of a K3 surface with a circle or a torus. A test of this equivalence is provided by calculating the new supersymmetric index on both sides of the duality. We examine the implications of these dualities for CHL-like orbifolds that reduce the rank of the gauge group, as well as those that lead to minimal supersymmetry in 4 dimensions. We also discuss properties of flux vacua that preserve minimal supersymmetry in 4 dimensions that cannot be related to conventional compactifications by Narain T-duality. Along the way we point out a number of properties of these vacua, including the role played by non-trivial flat gerbes, the appearance of rational worldsheet CFTs in decompactification limits, and the role of attractive K3 surfaces in backgrounds with minimal supersymmetry. Finally, we discuss the dual pairs from the perspective of M-theory/heterotic duality.
Superradiant instability of charged extremal black holes in Einstein-Born-Infeld gravity
Authors: Wu Zhe-Hua , Lü H. 
Published: July 2024

Abstract
We study charged scalar perturbations of charged extremal black holes in Einstein-Born-Infeld theory. Our numerical results indicate that these black holes all suffer from superradiant instability by the unstable quasi-bound states, regardless how small the coupling constant is. We therefore provide a new example that the superradiant stability of the Reissner-Nordström black hole is a fine-tuned result, as in the case when it is embedded in the STU supergravity model. The work is also motivated by the weak gravity conjecture since at the linear coupling constant level, the theory belongs to a subsect of four-derivative corrections in the effective field theory. Our results appear to support the notion that the black holes do decay when gravity is weaker by the correction, but the decaying halftime requires nonlinear effects and cannot be seen at the level of linear coupling constant. The full nonlinear effects also indicate that the black holes can decay even when gravity is stronger.
The Convergence of Some Positive Linear Operators on the Space of Multivariate Continuous Periodic Functions
Authors: Popa Dumitru 
Published: July 2024

AbstractAs a consequence of a general result, we prove that in the case of singular integrals the set of convergence consists only of the two functions $$\textbf{1}$$
1
and $$\cos $$
cos
. We prove also a multivariate version of this result and apply it to find the necessary and sufficient conditions for the convergence of the sequences of positive linear operators associated to the rectangular and triangular summation.
The Similarities in Microbial and Chemical Patterns of Fermentation in Two Open Environments were Promoted by Using 150-Year-Old Nukadoko as Starters

Published: July 2024

AbstractNukadoko, a fermented rice bran employed in traditional Japanese pickling, uses lactic acid bacteria to ferment vegetables. Here, we report the microbial and chemical data of a mixture of matured 150-year-old nukadoko and commercially available rice bran placed in two open environments over 29 days. Across the two environments, Loigolactobacillus was identified as the dominant microbial genera in the later stages of fermentation in nukadoko. The period of increase in the relative abundance of Loigolactobacillus correlated with a decrease in pH and Oxidation–Reduction Potential (ORP) values. While the two environments showed a difference in the rate of change in microbial diversity, they shared the common process through which Loigolactobacillus outcompeted adventitious bacteria in nukadoko, as indicated by the alpha and beta diversity index. Thus, the similarities in microbial and chemical data across two open environments during fermentation using starters indicate that starters contribute to the stability of fermentation in open environments.
Use of the Saccharomycopsis schoenii MET17 promoter for regulated heterologous gene expression
Authors: Rij Mareike , Wendland Jürgen 
Published: July 2024

AbstractThe ability to regulate the expression of genes is a central tool for the characterization of fungal genes. This is of particular interest to study genes required for specific processes or the effect of genes expressed only under specific conditions. Saccharomycopsis species show a unique property of necrotrophic mycoparasitism that is activated upon starvation. Here we describe the use of the MET17 promoter of S. schoenii as a tool to regulate gene expression based on the availability of methionine. Conditional expression was tested using lacZ and GFP reporter genes. Gene expression could be strongly down-regulated by the addition of methionine or cysteine to the growth medium and upregulated by starvation for methionine. We used X-gal (5-bromo-4-chloro-3-indolyl-β-d-galactopyranoside) to detect lacZ-expression in plate assays and ONPG (ortho-nitrophenyl-β-galactopyranoside) as a substrate for β-galactosidase in liquid-phase assays. For in vivo expression analyses we used fluorescence microscopy for the detection and localization of a MET17-driven histone H4-GFP reporter gene. With these assays we demonstrated the usefulness of the MET17 promoter to regulate expression of genes based on methionine availability. In silico analyses revealed similar promoter motifs as found in MET3 genes of Saccharomyces cerevisiae and Ashbya gossypii. This suggests a regulation of the MET17 promoter by CBF1 and MET31/MET32 in conjunction with the transcriptional activator MET4, which were also identified in the S. schoenii genome.
Towards a Classification of Steady-State Bifurcations for Networks with Asymmetric Inputs
Authors: Aguiar Manuela , Dias Ana , Soares Pedro 
Published: July 2024

AbstractWe consider homogeneous coupled cell networks with asymmetric inputs. We obtain general results concerning codimension-one steady-state bifurcations for networks with any number of cells and any number of asymmetric inputs. These results rely solely on the network adjacency matrices eigenvalue structure and the existence, or not, of network synchrony subspaces. For networks with three cells, we describe the possible lattices of synchrony subspaces annotated with the eigenvalues on each synchrony subspace. Applying the previous results, we classify the synchrony-breaking steady-state bifurcations that can occur for three-cell minimal networks with one, two or six asymmetric inputs.
Semantic guidance incremental network for efficiency video super-resolution

Published: July 2024

AbstractIn video streaming, bandwidth constraints significantly affect client-side video quality. Addressing this, deep neural networks offer a promising avenue for implementing video super-resolution (VSR) at the user end, leveraging advancements in modern hardware, including mobile devices. The principal challenge in VSR is the computational intensity involved in processing temporal/spatial video data. Conventional methods, uniformly processing entire scenes, often result in inefficient resource allocation. This is evident in the over-processing of simpler regions and insufficient attention to complex regions, leading to edge artifacts in merged regions. Our innovative approach employs semantic segmentation and spatial frequency-based categorization to divide each video frame into regions of varying complexity: simple, medium, and complex. These are then processed through an efficient incremental model, optimizing computational resources. A key innovation is the sparse temporal/spatial feature transformation layer, which mitigates edge artifacts and ensures seamless integration of regional features, enhancing the naturalness of the super-resolution outcome. Experimental results demonstrate that our method significantly boosts VSR efficiency while maintaining effectiveness. This marks a notable advancement in streaming video technology, optimizing video quality with reduced computational demands. This approach, featuring semantic segmentation, spatial frequency analysis, and an incremental network structure, represents a substantial improvement over traditional VSR methodologies, addressing the core challenges of efficiency and quality in high-resolution video streaming.
Menschen mit Demenz anlügen und täuschen? Eine prinzipienorientierte Falldiskussion
Authors: Erdmann Anke 
Published: July 2024

ZusammenfassungIn der Langzeitbetreuung von Menschen mit Demenz finden kommunikative Handlungen, die das Potenzial haben, Menschen mit Demenz zu täuschen, auf der Seite des Personals eine unterschiedliche Akzeptanz. Bushaltestellen, an denen kein Bus fährt, falsche Zugabteile, in denen ein Film die vorbeiziehende Landschaft simuliert, das Verstecken von Medikamenten in Nahrungsmitteln sind Interventionen, die Menschen in die Irre führen können, ohne ihnen tatsächlich falsche Informationen zu geben. Derartige kommunikative Praktiken wie Täuschungen, aber auch Lügen, definiert als absichtlich mitgeteilte irreführende Nachrichten, werfen die Frage auf, wie sie ethisch begründet werden können. Anhand einer fiktiven Fallschilderung, in dem eine Pflegeheimbewohnerin mit Hilfe eines vorgetäuschten Telefonanrufs daran gehindert wird, das Heim zu verlassen, zeige ich, dass die Täuschung, als eine von drei möglichen Handlungsoptionen, aus der Fürsorgeperspektive positiv bewertet werden kann, da die Bewohnerin ohne Zwang am Verlassen des Heimes gehindert wird. Das Prinzip der Autonomie aber wird verletzt, da die Bewohnerin nicht frei zwischen der Täuschung und der Realität wählen kann. Hinsichtlich der Verpflichtung gegenüber Dritten ist die Täuschung problematisch, da orientierte Bewohner und Bewohnerinnen die Szene beobachten und befürchten könnten, sie würden ebenfalls getäuscht. Die Synthese der verschiedenen Argumente zeigt, dass ein Spaziergang in Verbindung mit einem validierenden Gespräch als weitere Handlungsoption die Prinzipien der Fürsorge und Autonomie in Einklang bringt, aber aufgrund des Zeitaufwands das Risiko einer ungerechten Verteilung der Pflegeressourcen birgt.
Hemifacial microsomia: a scoping review on progressive facial asymmetry due to mandibular deformity
Authors: Atiba Peterson Makinde , Omotoso Bukola Rukayat , Madaree Anil , Lazarus Lelika 
Published: July 2024

Abstract
Purpose
This scoping review explores various parameters of the mandible in progressive facial asymmetry (FA) in hemifacial microsomia (HFM) patients, highlighting its relationship with sex, population, and age group.

Methods
The review was based on a comprehensive search of PubMed, EBSCOhost, and Web of Science. Eligible studies that met the inclusion criteria form part of the selection study. The included studies were appraised using screening and quantitative criteria of mixed-method appraisal tools. The authors utilised a pre-set data extraction form to obtain information from the included studies.

Results
Eleven studies met the inclusion criteria. The mandible parameters used were angular measurements, chin point, ramal height, body length, and total length. There was no relationship between FA and sex in HFM patients in the included studies. Most of the studies were comprised of European participants (55%), followed by Americans (36%) and Chinese (9%). The age groups included in the selected studies were categorised as dentition age (18%), early-to-middle childhood (18%), and varied ages (64%). The data presented in this review only pertains to the anomalous characteristics recorded on the affected side in HFM patients. No concomitant control data was recorded in this review.

Conclusion
An assessment of the included studies revealed that FA does not increase with age in HFM. Hence, FA is non-progressive in HFM patients. This information is relevant to diagnosing and managing HFM patients. More reports are needed on the progression of FA in HFM patients.
Comparison of in-person vs. remote administration of cognitive screening tools for people with ALS
Authors: Didcote Lyndsay , Vitoratou Silia , Al-Chalabi Ammar , Goldstein Laura H. 
Published: July 2024

Abstract
Objective
This study investigated whether cognitive screening tools used for people with amyotrophic lateral sclerosis (pwALS) are affected by the screen being administered face-to-face or remotely online. It also investigated whether demographic variables predicted total cognitive screen scores.

Methods
The cognitive component of the Edinburgh Cognitive and Behavioural ALS Screen (ECASc), the cognitive component of the ALS Cognitive Behavioural Screen (ALS-CBSc), and the Mini Addenbrooke’s Cognitive Examination (Mini-ACE) were administered to 41 pwALS and 41 controls face-to-face. Versions of the cognitive screens designed to be administered remotely were administered to 57 pwALS and 44 controls via videoconferencing methods.
Backwards stepwise linear regressions were conducted to assess whether total scores on the ECASc, ALS-CBSc, and Mini-ACE scores were predicted by administration mode (face-to-face or remote) or demographic variables.

Results
Mode of administration significantly affected scores on the ECASc and ALS-CBSc; remote administration was associated with better total scores. Administration mode did not significantly affect Mini-ACE scores. All cognitive screens were significantly affected by IQ scores; higher IQ scores predicted better screening tool scores. Only ECASc scores were significantly affected by age, with older age predicting poorer scores. Being female was associated with better Mini-ACE scores; sex did not predict ECASc and ALS-CBSc scores.

Conclusions
Our results suggest that videoconferencing versions of the ECASc and ALS-CBSc may function differently to the original, face-to-face versions. There are advantages to using remote versions of cognitive screening tools but clinicians and researchers who use them should consider that they may not yield equivalent scores.

Abstract
Background
The effects of tonsillectomy combined with steroid pulse (TSP) therapy for IgA nephropathy (IgAN) are little known. Therefore, we examined the effects of TSP therapy on the kidney outcomes of IgAN in a large, nationwide cohort study in Japan.

Methods
Between 2002 and 2004, 632 IgAN patients with ≥ 0.5 g/day proteinuria at diagnosis were divided into three groups with mild (0.50–0.99 g/day; n = 264), moderate (1.00–1.99 g/day, n = 216), or severe (≥ 2.00 g/day; n = 153). Decline in kidney function and urinary remission were compared among the three groups after TSP therapy, corticosteroid (ST) therapy, or conservative therapy during a mean follow-up of 6.2 ± 3.3 years. 10.6% and 5.9% of patients in the ST and conservative therapy group underwent tonsillectomy.

Results
The rate of urinary remission at the final observation was significantly higher in the TSP therapy group than in the ST or conservative therapy groups (mild proteinuria: 64%, 43%, and 41%; moderate proteinuria: 51%, 45%, and 28%; severe proteinuria: 48%, 30%, and 22%, respectively). In contrast, the rate of a 50% increase in serum creatinine was lower in groups TSP therapy, than ST or conservative therapy (mild proteinuria: 2.1%, 10.1% and 16.7%; moderate proteinuria: 4.8%, 8.8% and 27.7%; severe proteinuria: 12.0%, 28.9% and 43.1%, respectively). In multivariate analysis, TSP therapy significantly prevented a 50% increase in serum creatinine levels compared with conservative therapy in groups with moderate and severe proteinuria (hazard ratio, 0.12 and 0.22, respectively).

Conclusion
TSP significantly increased the rate of proteinuria disappearance and urinary remission in IgAN patients with mild-to-moderate urinary protein levels. It may also reduce the decline in kidney function in patients with moderate-to-severe urinary protein levels.
Day-after impact of simulated rival encounter in the common cuckoo
Authors: Winiarska Dominika , Jankowiak Łukasz , Tryjanowski Piotr , Osiejuk Tomasz S. 
Published: July 2024

AbstractStudies show that the common cuckoo exhibits a strong vocal response to rival playback. In this study, we aimed to assess if males would more eagerly vocally defend their home ranges a day after a simulated rival encounter. At 48 sites in Poland, we conducted a playback experiment where we played 20 calls repeated 5 times with a 5-min break between each series. Using the automatic analysis software Kaleidoscope Pro, we detected cuckoo calls in two datasets, directly after the experiment and the day after. Our results show that even though cuckoos respond to rival calls, this response is short-lived.

Published: July 2024

AbstractAlthough renal cell carcinoma (RCC) is a prevalent type of cancer, the most common pathological subtype, clear cell renal cell carcinoma (ccRCC), still has poorly understood molecular mechanisms of progression. Moreover, interferon-stimulated gene 15 (ISG15) is associated with various types of cancer; however, its biological role in ccRCC remains unclear.This study aimed to explore the role of ISG15 in ccRCC progression.ISG15 expression was upregulated in ccRCC and associated with poor prognosis. RNA sequence analysis and subsequent experiments indicated that ISG15 modulated IL6/JAK2/STAT3 signaling to promote ccRCC proliferation, migration, and invasion. Additionally, our animal experiments confirmed that sustained ISG15 knockdown reduced tumor growth rate in nude mice and promoted cell apoptosis. ISG15 modulates the IL6/JAK2/STAT3 pathway, making it a potential therapeutic target and prognostic biomarker for ccRCC.
Impact of common shade tree species on microclimate and cocoa growth in agroforestry systems in Ghana
Authors: Kohl Theresa , Niether Wiebke , Abdulai Issaka 
Published: July 2024

AbstractClimate change is a growing threat to agriculture globally, with most substantial impacts expected in tropical smallholder systems such as cocoa farms in West Africa. Cocoa agroforestry is widely believed to enhance resilience to climatic extremes due to protection and a favourable microclimate under the shade trees. Morphological traits of many locally used shade tree species and their specific contribution to microclimate for climate-resilient cocoa production remain unclear. Therefore, aboveground morphology and sub canopy microclimate of eight common shade tree species were investigated in cocoa agroforestry systems in the Ahafo region, Ghana. Additionally, the growth of cocoa trees in three different distance zones to the shade tree stem was measured. The eight different shade tree species exhibited considerable variation in their impact on microclimate and cocoa growth. M. indica and M. excelsa allowed lowest light transmission, with the highest microclimatic buffering effect, i.e., reducing vapour pressure deficit and daily fluctuations of temperature and relative humidity. Cocoa trees around M. lucida and F. capensis were the highest in growth, characterized by height and stem diameter. However, a universally superior shade tree species could not be identified implying the need for shade tree diversity allowing various microclimatic conditions within an agroforestry system to spread risk of climate extremes. Cocoa tree growth was more affected by distance to the shade tree than by shade tree species, resulting in enhanced growth with distance to the stem. These findings provide a better understanding of species-related differences on cocoa growing conditions and climate change adaptation strategies.

AbstractDocument-level relation extraction (RE) aims to predict the relational facts between two given entities from a document. Unlike widespread research on document-level RE in English, Korean document-level RE research is still at the very beginning due to the absence of a dataset. To accelerate the studies, we present (Toward Document-Level Relation Extraction in Korean) dataset constructed from Korean encyclopedia documents written by the domain experts. We provide detailed statistical analyses for our large-scale dataset and human evaluation results suggest the assured quality of . Also, we introduce the document-level RE model that considers the named entity-type while considering the Korean language’s properties. In the experiments, we demonstrate that our proposed model outperforms the baselines and conduct qualitative analysis.
Alternative green application areas for olive pomace catalytic pyrolysis biochar obtained via marble sludge catalyst

Published: July 2024

AbstractEvaluating industrial wastes in the system with minimum preprocessing and generation economically valuable products from them have critical importance. In this regard, especially cheap, wieldy, and readily available catalysts have been researched to increase variety of useful products in pyrolysis systems, to reduce process time, and to increase quality and diversity of products. Therefore, in this study, marble sludge (named K1) was evaluated as catalyst at different dosages (10%, 20%, 30%, 50%) and pyrolysis temperatures (300, 500, 700 °C) in olive pomace (OP) pyrolysis and; the potential green applications of produced new biochars at new usage areas with different purposes based on characteristics were investigated. ANOVA test results showed that temperature and catalysts ratio had significant effect on pyrolysis product yields since significance value for K1 and temperature was lower than 0.05 for pyrolysis products. OP-K1 biochars had alkaline properties and high earth metal quantities. Moreover, increment in K1 ratio and temperature resulted in decrement of the biochar surface acidity. Therefore, it can be indicated that these biochars can have a potential usage for anaerobic digestion processes, lithium-ion batteries, and direct carbon solid oxide fuel cell (DC-SOFC) but further electrochemical property test should be performed. Moreover, produced biochars can be alternative fuels in some processes instead of coal since they have low S content and high heat values. Consequently, it is foreseen that produced biochars will have an important place in the development of potential usage areas with a new and environmentally friendly approach in different areas apart from the conventional uses of catalytic pyrolysis chars.
