Coordinated dispatch of virtual power plants in distribution systems under ramping constraints and uncertainties

This paper proposes a coordinated dispatch framework for distribution systems with virtual power plants (VPPs) that addresses both substation ramping constraints and load-ramping uncertainty. A data-driven quantile-regression temporal convolutional network (QR-TCN) is developed t...

Evaluating age-related differences in motor imagery in children aged 5 to 8: feasibility and task-specific modulation

Motor imagery (MI), the mental simulation of movement without execution, provides a behavioural tool to evaluate sensorimotor representations. However, its characterisation in young children remains debated. This study investigated age-related differences in MI across early prima...

Burden of sickle cell anemia among hospitalized children in Angola: a retrospective study

Chronic pediatric diseases are a growing challenge because of their impact on morbidity and healthcare resource utilization. In Angola, evidence on the hospital burden of chronic diseases, particularly sickle cell anemia (SCA), remains limited. This study compared the clinical ch...

Are QM/MM models systematically improvable? A case study on carbonic anhydrase binding affinities

Hybrid quantum mechanics/molecular mechanics (QM/MM) is the method of choice for modelling large biochemical systems, but their performance depends critically on how they are implemented. This paper examines the sensitivity of QM/MM enzyme-ligand binding energy predictions to key...

Development and application of a methodological framework for assessing the resilience of military infrastructure against climate change impacts

Mitigating climate change impacts and enhancing the resilience capacity of military infrastructure is essential for the Armed Forces, first, to ensure a high level of both readiness and sustainability transitions and, second, to contribute to each European Union Member-State’s (E...

Artificial light-harvesting systems based on the Förster resonance energy transfer mechanism

One of the major global challenges lies in the efficient utilization of solar energy. Natural organisms primarily rely on photosynthesis to capture solar energy and store it as chemical energy, with light harvesting as a primary step. In natural light-harvesting systems, pigments...

Reference values and prediction equations for six-minute walk distance and stair-climbing test performance in apparently healthy Ethiopian adults

The six-minute walk test (6MWT) and stair-climbing test (SCT) are simple and practical measures of functional exercise capacity. Interpretation of performance requires appropriate population-specific reference values and prediction equations. However, reference data for apparentl...

Thoracic disc herniation and vascular vulnerability in a watershed zone

Anterior spinal artery (ASA) syndrome is a rare cause of spinal cord infarction and is most commonly associated with aortic pathology or systemic hypoperfusion. Disc herniation as a precipitating factor is exceptional, particularly in young, healthy individuals. We report the cas...

Combined effects of twin-screw extrusion parameters on physical, morphological, and microstructural properties of cassava-based analog rice

The production of analog rice has emerged as a potential approach for food fortification and diversification, particularly for populations that depend on rice as a staple food. Although the production of analog rice through extrusion has been widely practiced, detailed scientific...

Understanding cervical cancer screening disparities among Somali women in Southeast Minnesota: a community-engaged mixed methods study

Immigrant communities in southeast Minnesota, particularly Somali women, have significantly lower rates of cervical cancer screening uptake compared to the general population. We sought to learn more about this disparity by: (1) gaining a better understanding of the barriers and...

Effect of replacing groundnut seed cake with a brewer’s yeast–noug seed cake mixture in ration on egg quality, fertility and hatchability of White Leghorn chickens

The high cost and limited availability of conventional protein feed ingredients have increased the need for alternative protein sources in poultry diets. Therefore, this study evaluated the effect of replacing groundnut seed cake with a brewer’s yeast–noug seed cake (BYNSC) mixtu...

Theca cell monolayer co-culture improves oocyte in vitro maturation and subsequent embryo development in buffalo (Bubalus bubalis)

Theca cells (TCs) are essential regulators of both follicular development and regression, as they produce androgens that serve as precursors for granulosa cell aromatization. The present study aimed to examine the effects of TC monolayer co-culture on oocyte in vitro maturation (...

Land use impairs soil quality in a Histosol: a comparative study between conventional cultivation and secondary forest

Histosols provide key ecosystem services, including carbon storage, hydrological regulation, and biodiversity support; however, the effects of conventional agriculture on their quality in tropical regions remain poorly understood. In this study, we evaluated the effects of differ...

Flow cytometry as a tool for assessing reactive oxygen species-related fluorescence in peripheral blood leukocytes from children and adolescents with asthma

Background Asthma is characterized by airway inflammation and bronchial hyperreactivity, with increased production of reactive oxygen species (ROS). Assessing oxidative stress is relevant to disease pathophysiology, but many methods have limitations in pediatric populations . Obj...

Reliability assessment of parallel-connected 3L-NPC machine-side converters in offshore wind turbines considering post-fault load redistribution

Parallel-connected machine-side converters provide redundancy for offshore direct-drive wind turbines, but a local submodule failure increases the current stress and accelerates degradation of the surviving units. Conventional fixed-load k -out-of- n reliability models do not cap...

Depressive Symptom Predictors in Older Mexican Adults: Interaction Structures and Nonlinear Effects from Machine Learning Explainability

Background Depression among older adults remains a critical public health issue in Latin America, where aging populations face compounded social and health vulnerabilities. Objective To characterize psychosocial and clinical predictors of depressive symptoms among older Mexican a...

Public antibiotic resistance mechanisms in Salmonella can maintain inhibition by probiotics during antibiotic treatment

Probiotics are being explored as a sustainable alternative to antibiotics that can also inhibit antibiotic-resistant pathogens. However, probiotics generally show a lower killing efficacy against susceptible pathogens compared to traditional antibiotics. Combining probiotics with...

Hybrid control with half-cycle adaptive switching rule and integral action for a Totem-Pole bridgeless rectifier

This paper proposes a hybrid control strategy for a single-phase Totem-Pole Bridgeless Rectifier (TPBR), modeled as an affine switched system combining controlled and autonomous dynamics under parametric uncertainties. The TPBR is analytically characterized as a current-dependent...

Bumblebee pollen collection is a costly affair

Pollen is an essential nutrient used by bees to rear their larvae and, minimally, for adult nutrition [1 ].Across bee species, females have evolved several different methods for collecting pollen, typically using movements of their fore, mid

Anti-cancer and anti- genotoxic potential of Yoom Noon rice: induction of apoptosis, cell cycle arrest, and inhibiting migration and invasion in vitro

Yoom Noon, a strain of rice from the Royal Initiative of Southern Thailand, is rich in flavonoids and exhibits strong antioxidant properties. However, no research has yet been conducted on its anti-cancer properties, leading us to explore the activity of polished and unpolished Y...
