Wind turbines hold substantial promise for harnessing wind energy, yet the blades endure severe unsteady aerodynamic loads due to prolonged operation in complex environments. These loads adversely affect both aerodynamic and structural performance. The aerodynamic and structural properties of airfoils are critical determinants of overall blade effectiveness. To enhance aerodynamic and anti-flutter

Embedding thermoelectric coolers (TECs) within thermal management systems is a promising approach for addressing localized heat. The required thermoelectric (TE) material properties for achieving a high cooling rate depend on the operating mode of TECs—refrigeration or active cooling—which is determined by the internal Fourier heat direction within the TE legs. Therefore, analyzing the operating mode

Isolated microgrids generate excess energy (Pexg) up to 70.1% of total generation, disturbing supply reliability and protection systems. This study presents the Pexg management, optimal design, and techno-economic-environmental analysis in a Hybrid Renewable Energy System (HRES) based isolated microgrid. The optimal sizing is obtained with the minimization of Levelized Cost Of Energy (LCOE), subject

The cerebellar ventricular zone (VZ) is the primary source of progenitors that generate cerebellar GABAergic neurons, including Purkinje cells (PCs) and interneurons (INs). This study provides detailed characterization of human cerebellar GABAergic neurogenesis using transcriptomic and histopathological analyses and reveals conserved and unique features compared to rodents. We show that the sequential

Large-scale integration of microbattery systems on chips has long been hindered by the technical barrier between electrochemistry and microelectronics, particularly in terms of the compatibility of microbattery cells and their collective manufacturability. In this work, a silicon-based all-solid-state thin-film microbattery cell is developed at low temperatures for on-chip integration applications

The collective motion of epithelial cells is a fundamental biological process which plays a significant role in embryogenesis, wound healing, and tumor metastasis. While it has been broadly investigated for over a decade both in vivo and in vitro, large-scale coherent flocking phases remain underexplored and have so far been mostly described as fluid. In this work, we report an additional mode of large-scale

Structural homeostasis and proper distributions of signaling molecules in cilia require a constant flow of cargoes carried by intraflagellar transport (IFT) trains in both anterograde and retrograde directions within the thin, long ciliary shafts. In the motile cilium framework, the nine microtubule doublets of the same length serve as the transportation rails, and a preferential association to the

Brain oscillations in different behavioral states are essential for cognition, and oscillopathies contribute to cognitive dysfunction in neuropsychiatric diseases. Cannabis-1 receptor (CB1-R) activation was reported to suppress theta and fast gamma activities in rats during waking exploration, and here, we show that cannabis fundamentally alters network activity during sleep as well. Prominent theta

Understanding how localized brain interventions influence whole-brain dynamics is essential for deciphering neural function and designing therapeutic strategies. Using longitudinal functional MRI datasets collected from mice, we investigated the effects of focal interventions, such as thalamic lesions and chemogenetic silencing of cortical hubs. We found that these local manipulations disrupted the

Excitatory amino acid transporters (EAATs) reside on cell surfaces and uptake substrates, including L-glutamate, L-aspartate, and D-aspartate, using ion gradients. Among five EAATs, EAAT3 is the only isoform that can efficiently transport L-cysteine, a substrate for glutathione synthesis. Recent studies suggest that EAAT3 also transports the oncometabolite R-2-hydroxyglutarate (R-2HG). Here, we examined

The MRE11/RAD50/NBS1 (MRN) complex plays multiple roles in the maintenance of genome stability. MRN is associated with replication forks to preserve fork integrity and is also required for end resection at double-strand breaks (DSBs) to facilitate homologous recombination (HR). The critical need for proper control of the MRE11 nuclease activity is highlighted by the extensive nascent strand DNA degradation

Bestrophin-1 (BEST1) is a chloride channel expressed in the eye and other tissues of the body. A link between BEST1 and the principal inhibitory neurotransmitter γ -aminobutyric acid (GABA) has been proposed. The most appreciated receptors for extracellular GABA are the GABA B G-protein-coupled receptors and the pentameric GABA A chloride channels, both of which have fundamental roles in the central

Interdisciplinary research is essential for addressing complex global challenges, but there are concerns that scientific institutions like journals select against it. Prior work has focused largely on how interdisciplinarity relates to outcomes for published papers, but which papers get accepted for publication in the first place is unclear. Furthermore, journals may evaluate two key dimensions of

Pseudohypoparathyroidism type 1B (PHP1B) is a multihormone resistance disorder caused by aberrant GNAS methylation. Characteristic epigenetic changes at GNAS differentially methylated regions (DMRs), i.e., NESP, AS1, AS2, XL, and A/B, are associated with specific structural defects in different autosomal dominant PHP1B (AD-PHP1B) subtypes. However, mechanisms underlying abnormal GNAS methylation remain

Membrane frizzled-related protein (MFRP), present in the retinal pigment epithelium (RPE), is an integral membrane protein essential for ocular development and the normal physiology of the retina. Mutations in MFRP are associated with autosomal recessive nonsyndromic nanophthalmos, leading to severe hyperopia and early-onset retinitis pigmentosa. While several preclinical gene-augmentation and gene-editing

Spatial epigenomics and multiomics can provide fine-grained insights into cellular states but their widespread adoption is limited by the requirement for bespoke slides and capture chemistries for each data modality. Here, we present SPatial assay for Accessible chromatin, Cell lineages, and gene Expression with sequencing (SPACE-seq), a method that utilizes polyadenine-tailed epigenomic libraries

The elastic properties of nanoscale extracellular vesicles (EVs) are believed to influence their cellular interactions, thus having a profound implication in intercellular communication. However, accurate quantification of their elastic modulus is challenging due to their nanoscale dimensions and their fluid-like lipid bilayer. We show that the previous attempts to develop atomic force microscopy-based

We report a transition from the ferroelectric nematic liquid crystal (N F ) phase to a lower-temperature, apolar fluid phase having reentrant isotropic symmetry (I R ), in the liquid crystal compound RM734 doped with small concentrations of the ionic liquids 1-Butyl-3-methylimidazolium hexafluorophosphate (BMIM-PF 6 ) or 1-Ethyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide (EMIM-TFSI). Even

Elevated miR-155 levels in B cell malignancies, such as CLL and DLBCL, correlate with increased aggressiveness of the disease. We recently reported that, in two different mouse models of miR-155 -driven B cell malignancy, miR-155 targets and down-regulates transcripts encoding ICOSL, the ligand for the Inducible T cell costimulator (ICOS), thereby impairing the capacity of T lymphocytes to recognize

Phospholipase Cβ (PLCβ) enzymes are the principal effectors activated by G q heterotrimers. Both Gα q and Gβγ subunits can activate PLCβ, which requires precise positioning of PLCβ at the plasma membrane to relieve structural autoinhibition and give the active site access to the phosphatidylinositol 4,5-bisphosphate (PIP2) substrate. PLCβ enzymes possess a unique distal C-terminal domain (dCTD) that
