Authors: Prasad Ankush , Mihačová Eliška , Manoharan Renuka Ramalingam , Pospíšil Pavel 
Published: January 2025

AbstractThe oxidative damage induced by abiotic stress factors such as salinity, drought, extreme temperatures, heavy metals, pollution, and high irradiance has been studied in Arabidopsis thaliana. Ultra-weak photon emission (UPE) is presented as a signature reflecting the extent of the oxidation process and/or damage. It can be used to predict the physiological state and general health of plants. This study presents an overview of a potential research platform where the technique can be applied. The results presented can aid in providing invaluable information for developing strategies to mitigate abiotic stress in crops by improving plant breeding programs with a focus on enhancing tolerance. This study evaluates the applicability of charged couple device (CCD) imaging in evaluating plant stress and degree of damage and to discuss the advantages and limitations of the claimed non-invasive label-free tool.
Entropy Generation Rate as a Marker for the Onset of Flame Instability
Authors: Zhumabayeva Daniya , Cant Robert Stewart 
Published: January 2025

AbstractA comprehensive understanding of the mechanisms of intrinsic flame instability, including hydrodynamic and thermodiffusive instabilities, is becoming more important with the move towards greater reliance on hydrogen as a zero-carbon fuel. While intrinsic flame instabilities have been studied extensively both numerically and experimentally, certain important features, including their onset, have been defined mainly by qualitative measures. This work proposes a quantitative marker to identify the onset of intrinsic flame instabilities derived from the statistics of the entropy equation. Direct numerical simulations were carried out for two-dimensional laminar premixed planar methane-air flames, with varying amounts of hydrogen addition up to 100% by volume. Entropy generation mechanisms were analysed based on contributions resulting from heat conduction, viscous dissipation, mass diffusion, and chemical reaction. Instability onset was shown to be characterised by increased data dispersion in all entropy generation terms. The dispersion was quantified by the statistical range, which increased for all locations within the flame as the flame transitioned into instability. Increasing hydrogen addition resulted in a delayed instability onset attributed to the decreasing hydrodynamic instability growth rate. The entropy generation rate due to viscous dissipation was found to be smaller in magnitude compared to other mechanisms, but it was found to be the most sensitive indicator of instability onset. This quantity is readily computed using data from numerical simulations and can be estimated from experimental data, suggesting its potential use as a marker of intrinsic flame instability.

Abstract
Sociodemographic disadvantage is a stressor related with unsupportive parenting practices, but little is known about the process by which it may undermine early parental emotion socialization. In the current study, we examined (1) the direct association between sociodemographic risk and supportive emotion socialization and (2) possible indirect effects via psychological distress and mother-oriented cry processing (i.e., negative cognitions about crying) in a short-term 3-wave longitudinal study that followed a stratified sample of 259 first-time mothers from pregnancy through 14-months postpartum. Sociodemographic risk included mothers’ age, education, and income reported by the expectant mothers prenatally. Psychological distress was assessed prior to the 6-month laboratory visit using mothers’ reports on depressive symptoms, difficulty regulating emotions, and trait positive and negative emotions. During the 6-month laboratory visit, mother-oriented cry processing was assessed using a video-recall procedure. Supportive emotion socialization at 14 months was assessed based on observer-rated maternal sensitivity during two distress eliciting tasks and maternal reports. Consistent with prediction, the first indirect pathway from higher sociodemographic disadvantage to lower supportive emotional socialization through higher mother-oriented cry processing was statistically significant, however the second indirect pathway from higher sociodemographic disadvantage to higher psychological distress to higher mother-oriented cry processing to lower supportive emotion socialization was not. Over and above these indirect effects, higher sociodemographic disadvantage was directly associated with lower supportive emotion socialization. Psychological distress was not significantly directly associated with emotion socialization. These findings highlight the importance of policies and interventions that provide financial assistance to the mothers experiencing sociodemographic disadvantage and target their psychological wellbeing.

Published: January 2025

Abstract
Parenting is a product of complex, interactive, and interwoven factors, which are affected by a variety of characteristics, including parent characteristics and the family environment. Such characteristics, including marital dissatisfaction and poor mental health, could place infants at an increased risk for affect regulation difficulties. The current longitudinal study extended previous research by examining how multiple factors of the parenting environment are associated with infant affect regulation with mothers and fathers. Families (n = 89, primarily White) from the Southeastern United States were assessed at 4 and 8 months of age. Parent mental health (anxiety and depression symptoms, well-being) and marital satisfaction were measured by questionnaires when infants were 4 months old. Infant affect regulation was measured via infant affect observational ratings during a face-to-face play task at 4 and 8 months of age. Mothers, who were higher in well-being, had infants lower in negative affect. Infants, whose fathers were low in social anxiety and had higher marital satisfaction, had decreased levels of negative affect. Findings provide target areas for promoting infant affect regulation, such as parent marital satisfaction and parent mental health.

Published: January 2025

AbstractRhythm perception in speech and non-speech acoustic stimuli has been shown to be affected by general acoustic biases as well as by phonological properties of the native language of the listener. The present paper extends the cross-linguistic approach in this field by testing the application of the iambic-trochaic law as an assumed general acoustic bias on rhythmic grouping of non-speech stimuli by speakers of three languages: Arabic, Hebrew and German. These languages were chosen due to relevant differences in their phonological properties on the lexical level alongside similarities on the phrasal level. The results show Iambic-Trochaic-Law (ITL) conforming weak–strong grouping for duration-cued acoustic salience. However, only German participants judged intensity-varying sequences as strong–weak; no grouping preferences were found for speakers of Arabic and Hebrew. Overall these results suggest that prosodic properties of the phonological phrase and of the lexical level of the native language show differing effects on rhythmical grouping.
Optimizing urban blue-green space in climate adaptive planning: a systematic review of threshold value of efficiency thresholds
Authors: Han Mingxiao , Zhang Tingting , Si Zhen 
Published: January 2025

Abstract

Context
Although various methods exist to mitigate the urban heat island (UHI) effect, urban blue-green spaces (UBGS) are considered particularly effective. Understanding the threshold value of efficiency (TVoE) for UBGS can optimize urban land use and spatial planning.

Objectives
This study systematically reviews the TVoE of UBGS to provide urban managers and landscape designers with comprehensive insights for climate-adaptive planning. We aim to summarize the distribution patterns and influencing factors of the TVoE, identify current research limitations and future directions and offer planning and research recommendations.

Methods
We conducted a systematic literature review (SLR) following the PRISMA guidelines, analyzing publications on the TVoE of UBGS from the Web of Science, PubMed, and Scopus databases.

Results
The distribution patterns of the TVoE of UBGS are influenced by spatial types, latitude, and climate. Generally, the TVoE of urban green spaces (UGS) increases with decreasing latitude and increasing humidity, whereas the TVoE of parks and urban blue spaces (UBS) decreases with decreasing latitude and increasing humidity. The studies reviewed focus on the impact of landscape features of UBGS on cooling effects, while patch surrounding environmental and meteorological factors are less frequently mentioned. Cost-effective urban planning should prioritize UBS with complex shapes in low-latitude, humid regions, while in high-latitude, arid areas focusing on UGS with regular shapes. Future research should explore vertical structures within UBGS, surrounding environmental factors, and Local Climate Zones (LCZ) to enhance understanding of climate-adaptive planning.
Relation-Guided Versatile Regularization for Federated Semi-Supervised Learning

Published: January 2025

AbstractFederated semi-supervised learning (FSSL) target to address the increasing privacy concerns for the practical scenarios, where data holders are limited in labeling capability. Latest FSSL approaches leverage the prediction consistency between the local model and global model to exploit knowledge from partially labeled or completely unlabeled clients. However, they merely utilize data-level augmentation for prediction consistency and simply aggregate model parameters through the weighted average at the server, which leads to biased classifiers and suffers from skewed unlabeled clients. To remedy these issues, we present a novel FSSL framework, Relation-guided Versatile Regularization (FedRVR), consisting of versatile regularization at clients and relation-guided directional aggregation strategy at the server. In versatile regularization, we propose the model-guided regularization together with the data-guided one, and encourage the prediction of the local model invariant to two extreme global models with different abilities, which provides richer consistency supervision for local training. Moreover, we devise a relation-guided directional aggregation at the server, in which a parametric relation predictor is introduced to yield pairwise model relation and obtain a model ranking. In this manner, the server can provide a superior global model by aggregating relative dependable client models, and further produce an inferior global model via reverse aggregation to promote the versatile regularization at clients. Extensive experiments on three FSSL benchmarks verify the superiority of FedRVR over state-of-the-art counterparts across various federated learning settings.

Published: January 2025

AbstractA 33-year-old woman with morbid obesity, positive IgM cardiolipin antibody, and recurrent venous thromboembolism on weight-based enoxaparin treatment developed severe headaches during her 9th week of pregnancy and was diagnosed with cerebral vein thrombosis (CVT). She was treated with enoxaparin (1 mg/kg) 240 mg twice daily, after a few days of intravenous heparin. Her complete blood count showed mild pancytopenia, with normal peripheral smear. She had a normal bone marrow biopsy done due to leukocytosis a year ago. She few days later presented to our emergency department (ED) with worsening headache and photophobia. Workup revealed normal anti-Xa activity despite weight-based enoxaparin, CVT, and a new diagnosis of acute promyelocytic leukemia. While it is known that APML predisposes to thrombotic events, there is limited literature that reports enoxaparin-resistant CVT as an initial manifestation of APML. It is important for clinicians to be aware that occurrence of unusual thromboembolism may herald APML.
Auroral Acceleration at the Northern Magnetic Pole During Sub‐Alfvénic Solar Wind Flow at Earth

Published: January 2025

AbstractBetween 23 and 25 May 2002 the solar wind, due to very low plasma density, became sub‐Alfvénic for enough time to promote the establishment of Alfvén wings that can limit typical solar wind‐magnetosphere coupling. During this interval, the interplanetary magnetic field (IMF) was oriented northward and duskward, with a slightly dominant component; driving of the magnetosphere was expected to be low. Many signatures are used to assess solar wind‐magnetosphere‐ionosphere coupling, including ultraviolet (UV) observations of the auroral zone to infer monoenergetic electron precipitation and radio observations of auroral kilometric radiation (AKR) to infer the development of the auroral acceleration region. Observing these signatures with the IMAGE (Imager for Magnetopause‐to‐Aurora Global Exploration) and Wind spacecraft, we find evidence of auroral acceleration that allowed amplification of AKR to similar intensities as during super‐Alfvénic coupling. This coincides with polar electron aurora around square in latitude and at magnetic latitudes greater than 88. The multipoint radio observations imply sources are generated along a constrained flux tube. Given the primary coincidence of AKR and the electron polar spot 3 hr following the incidence of minimally sub‐Alfvénic solar wind at Earth, this acceleration occurs while the Alfvén wings are most complete. Given the IMF conditions, auroral morphology of the polar spot and the inference of an upward field‐aligned current, the magnetospheric dynamics are most related to those of the high‐latitude dayside aurora (HiLDA). These observations are the first to show AKR amplification from HiLDA and during a sub‐Alfvénic magnetosphere, highlighting the possibility of strong localized coupling under quiet geomagnetic conditions.

AbstractThe γ-tubulin ring complex (γ-TuRC) is a structural template for controlled nucleation of microtubules from α/β-tubulin heterodimers. At the cytoplasmic side of the yeast spindle pole body, the CM1-containing receptor protein Spc72 promotes γ-TuRC assembly from seven γ-tubulin small complexes (γ-TuSCs) and recruits the microtubule polymerase Stu2, yet their molecular interplay remains unclear. Here, we determine the cryo-EM structure of the Candida albicans cytoplasmic nucleation unit at 3.6 Å resolution, revealing how the γ-TuRC is assembled and conformationally primed for microtubule nucleation by the dimerised Spc72 CM1 motif. Two coiled-coil regions of Spc72 interact with the conserved C-terminal α-helix of Stu2 and thereby position the α/β-tubulin-binding TOG domains of Stu2 in the vicinity of the microtubule assembly site. Collectively, we reveal the function of CM1 motifs in γ-TuSC oligomerisation and the recruitment of microtubule polymerases to the γ-TuRC.

AbstractTooth degradation develops easily over time from initial caries to deeper cavities. The quality and durability of restorations are crucial in a patients’ life, and it is primarily determined by the mechanical properties of the restorations. Clinicians and engineers apply biomimetic science in dentistry to mimic the natural design of the teeth and emphasize careful material selection as well as bond strength between the tissue and artificial material. The aim of this research was to develop and compare five different bulk filling restoration techniques for high C-factor (5.0) Class I cavities and determine the most durable technique. Tensile bond strength between the dentin and the filling, as well as the inner structure of the filling was measured via computed tomography, scanning electron microscopy and mechanical testing methods. It was found that the semi-direct bulk filling technique (bulk filling with an extra, indirect curing step) can increase the tensile bond strength on average by 58% (51.1 ± 12.2 MPa) compared to the direct bulk filling method with the same materials (32.4 ± 8.2 MPa). The introduced semi-direct technique allows bulk filling to be used on Class I cavities while achieving a high bond strength, resulting in highly durable and reproducible restorations.

AbstractEnvironmental heat stress causes significant economic loss in the poultry industry. Therefore, interest has increased in using feed additives to reduce the negative impacts of heat stress on the chickens and improve production performance. This study aimed to assess the effect of supplementing with Nigella sativa nanoparticles (Nano-NS) as an anti-stress and growth promoter in broiler diets under hot climatic conditions. A total of 375 male one-day-old Ross 308 chicks were randomly divided into a control group and four treatment groups (75 chicks/group). The first group fed a basal diet without additives, the second group fed a basal diet supplemented with avilamycin at 50 mg/kg, and the other groups fed a basal diet supplemented with 30, 40, and 50 mg/kg Nano-NS, respectively. Despite that feed intake was not affected, feed conversion ratio, body weight gain, and crude protein digestibility improved in broilers fed Nano-NS (P < 0.05) compared with avilamycin and the control groups. Adding Nano-NS led to an increase in the dressing percentage and the relative weight of the bursa of Fabricius and thymus. Serum high-density lipoprotein levels increased while total cholesterol and low-density lipoprotein concentrations decreased (P < 0.05) in broilers fed Nano-NS compared with control groups. Furthermore, Nano-NS supplementation significantly increased (P < 0.05) serum immunoglobulin (IgG and IgA), and superoxide dismutase (SOD) levels, while decreasing malondialdehyde (MDA), interleukin-6 (IL-6), and tumor necrosis factor-alpha (TNF-α) concentration. Moreover, there was a significant increase in the Lactobacillus population and a decrease (P < 0.05) in the E. coli and C. perfringens population in chicks fed Nano-NS. In the intestinal tissues, mucin 2 (MUC2) gene expression increased in chickens fed 50 mg/kg Nano-NS compared to other groups. It is concluded that adding Nano-NS (up to 50 mg/kg) reduced the negative effects of heat stress via enhancing growth performance, immune responses, and antioxidant status, modulating the microbial community structure, and increasing the expression of the MUC2 gene in broilers under high ambient temperature.
