An integrated circularity and life cycle assessment of power electronic converters: key hotspots and improvement opportunities

The rapid electrification of energy systems relies heavily on power electronic converters (PECs), which enable efficient electricity conversion and control in applications such as industrial drives, renewable energy systems, and electric mobility. However, despite their high oper...

Invariance Without a Beneficiary: What Survives Cognitive Parity, and on What Grounds

Past the parity threshold this corpus has closed route after route, and read quickly the series says that nothing holds. It does not say that. Every closed route was a configuration whose working condition contained a relative capacity term, and the complementary question was nev...

Incidentally detected elevated jugular venous pressure revealing a delayed post-CABG ascending aortic pseudoaneurysm near a saphenous vein graft origin: a case report

Ascending aortic pseudoaneurysm is an uncommon but potentially life-threatening delayed postoperative complication of cardiac surgery, arising at previous aortic manipulation sites. It may remain clinically silent until expansion, compressive effects, contained rupture, or catast...

Comparison of Single-Channel and Double-Channel Flow Characteristics in Downward-Facing Heating Channel of Core Catcher

원전 중대사고 발생 시 유럽 등 일부 국가 원전에서는 원자로에서 방출되는 노심용융물을 코어캐처에 모은 뒤 냉각수를 이용해 순환 유동을 발생시켜 코어캐처 및 노심용융물 전체를 냉각시키는 전략을 채택하고 있다. 본 연구에서는 이때 코어캐처 하부 구조의 변화에 따른 냉각 및 유동 변화를 확인...

A systematic review of deep learning techniques for learners’ engagement prediction in electronic learning systems

Electronic learning enables learners to acquire knowledge outside the confines of a classroom. However, engagement is of significant concern, as the system does not facilitate one-on-one monitoring. To propose innovative systems capable of forecasting learners’ engagement, it is...

Effect of application delays on the dentin bond strength and interfacial morphology of different adhesive systems: an SEM analysis

This study evaluated the effect of application delays on the dentin bond strength of different adhesive systems used in composite restorations. Forty-five extracted human molars were randomly assigned to Clearfil SE Bond, G-Premio Bond, and Single Bond Universal ( n = 15). Each a...

The Universe Exists Only in This Instant

Based on the author's previously proven Closed-System Self-Update Paradox (Chen, 2026a), this paper extrapolates the conclusion to a cosmological model. We first clarify the conditionality of this extrapolation: if the universe satisfies (1) finite information capacity and (2) ab...

MMAllo: a multimodal deep learning framework and GaMD simulations for predicting protein allosteric sites and allosteric mutations

Allosteric regulation, whereby small molecules or mutations modulate protein function from sites distal to the orthosteric active site, is a pervasive mechanism of biological control and an important opportunity for drug discovery. Yet the prospective identification of allosteric...

Does cross-border regulatory cooperation reduce excessive risk-taking?

This study investigates how heightened regulatory scrutiny by the U.S. Securities and Exchange Commission (SEC), caused by the passage of the Multilateral Memorandum of Understanding (MMoU), affects excessive risk-taking by U.S. listed foreign firms. Using data from 37 countries...

Energy efficiency of miscanthus insulation for building walls in various world climates

The building sector is a major contributor to global energy consumption, highlighting the need for efficient and sustainable insulation materials. This study investigates the thermal and energy performance of miscanthus-based bio-sourced insulation applied to exterior building wa...

Native myocardial T1 reference values in a tunisian cohort using MOLLI and SMART1Map

Native T1 values in cardiac magnetic resonance (CMR) are influenced by acquisition sequence, physiological factors, and site-specific variability, complicating clinical interpretation. The absence of population-specific reference values further limits diagnostic accuracy. This st...

Clinical and molecular characteristics of thalamic gliomas in adults: prognostic impact of TERT promoter mutation

BACKGROUND: Adult thalamic gliomas (ATGs) are rare and biologically heterogeneous tumors. Although the 2021 World Health Organization (WHO) classification designates all diffuse midline gliomas (DMGs), H3-altered, as grade 4, accumulating evidence suggests that adult thalamic DMG...

Spatial ecotype in tumor immune exclusion: from spatial architecture to therapeutic strategies

The tumor microenvironment (TME) exhibits widespread immunophenotypic heterogeneity. Based on the spatial immune contexture, tumor immune profiles can be classified as immune-inflamed, excluded, or desert. Immune-excluded tumors, a distinct tumor immune phenotype, are characteriz...

Subjective well-being of healthcare workers after Japan’s COVID-19 state of emergency

Healthcare workers (HCWs) are the cornerstone of pandemic response, yet their subjective well-being may be compromised by unavoidable occupational risks. While current research has documented the immediate psychological impact of COVID-19, fewer studies have tracked how self-repo...

Utilizing the antidermatophytic potential of aromatic essential oils and their major constituents against clinically relevant dermatophytes

Dermatophytosis is a common fungal infection of keratinized tissues (skin, hair, nails) caused by dermatophyte fungi. Conventional treatments rely on synthetic antifungals that can be costly, slow-acting, and prone to resistance or side effects. This has spurred interest in natur...

The Visualization of Jomon One-Dimensional Coordinate System

Every line segment has two endpoints. Ala denotes that the component of the tuple is the first component.

“When teaching turns turbulent: a mixed-methods study on prioritizing critical incidents of health sciences teachers”

Critical incidents significantly impact teacher identity, either constructively or disruptively. However, without knowing which incidents are most impactful, interventions and long-term plans cannot be designed. This study aimed to identify and prioritize critical incidents from...

Contrasting seasonal roles of external forcing and internal variability in East Asian temperature

How to reliably separate external forcing (EXF) and internal variability (IV) components of regional temperature variation is of critical importance in East Asia. We implement here an EOF-based semi-empirical framework to avoid spurious teleconnections often present with conventi...

Valorisation of Zingiber officinale hydrodistillation residual cake as a sustainable source of bioactive gingerols and shogaols: Quantification by validated HPLC-DAD and multi-spectroscopic characterization

Zingiber officinale Roscoe (ginger) hydrodistillation for essential oil production generates large quantities of residual cake, an underutilized by-product rich in non-volatile phenolics. This study characterized and quantified gingerols and shogaols in fresh Ecuadorian ginger rh...
