This study examines the realised volatility spillover effects between Malaysia's energy market and other sectoral indices on the Kuala Lumpur Stock Exchange from September 2018 to December 2024. To address the limitation...

Objective and MethodTo achieve rapid coalbed methane (CBM) extraction from broken-soft coal seams using surface horizontal wells, this study proposed a volume fracturing technology for coal seam roof using horizontal wel...

Purpose — This paper examines the relationship between South Africa’s rising public debt and real exchange rate (RER) volatility. Over the past two decades, the country has experienced an alarming increase in externa...

Three-phase pulse width modulation (PWM) rectifiers are crucial in industrial, civil, and transportation applications. Due to the diversity of grid loads, the three-phase input voltage may be unbalanced, which consequent...

To address the challenges of voltage deviation and increased network losses arising from the high integration of photovoltaic (PV) systems in distribution networks, this paper proposes a bi-level optimisation model for c...

Background and purposeRadiotherapy (RT) often causes delayed radiation-induced brain injury (RBI) with unclear pathophysiology; emerging evidence links this to glymphatic dysfunction, but radiation effects on cerebrospin...

With the proposal of the national dual-carbon strategic goal, distributed photovoltaic (PV) ushers in new development opportunities, and the management of voltage quality for photovoltaic power stations becomes a key cha...

Abstract Purpose This study aims to introduce an effective protocol for transvaginal ethanol sclerotherapy, focussing on the aspiration of viscous cystic content and the amount of ethanol instilled in the cystic cavity a...

Traditional bibliometric indicators such as the h-index emphasize cumulative citation impact but provide limited insight into the efficiency and concentration of that impact across a researcher's publication portfolio. T...

This describes a low-energy voltage level shifter (LS) architecture. We further introduce a regulated cross-coupled (RCC) pull-up network to achieve a considerable reduction in dynamic power consumption with higher switc...

This study investigates the effect of discharge voltage on fracture distribution and fragmentation extent in multi-hole pulsed discharge rock fragmentation. Comparative experiments were conducted on red sandstone specime...

Aiming at the problem that the topology of low-voltage distribution network is complex and leads to low fault segment localization accuracy, a fault segment localization method based on voltage difference network mapping...

Estimating three-dimensional morphological traits such as volume from two-dimensional RGB images presents inherent challenges due to the loss of depth information, projection distortions, and occlusions under field condi...

Grid-forming (GFM) converters are increasingly deployed to support power system stability in low-inertia grids. However, the impact of voltage magnitude control strategies on transient stability under fault conditions re...

This study provides an empirical analysis of the volatility dynamics of the Deutscher Aktienindex (DAX) stock index over a 20-year period based on daily observations, specifically from January 2, 2006, to March 20, 202...

Kai Wang,1,2,* Shuhan Zhang,1,* Zhaoyu Lv,1,* Wei Chen,1 Yonghua Li1 1Department of Anesthesiology, Second Affiliated Hospital of Naval Medical University (Shanghai Changzheng Hospital), Shanghai,...

This paper introduces a voltage regulation technique for an isolated power electronic converter that interconnects multiple transformers in series or parallel configurations using switches. This topology, known in the li...

Background and Study Aim. Finger flexor strength and endurance are components of lead climbing performance. Climbers develop these qualities within specific training environments shaped by facility characteristics and co...

Abstract Objective Accurate preoperative stone size assessment is crucial for predicting outcomes after percutaneous nephrolithotomy (PCNL), yet a gap persists between the accurate but impractical gold standard (3D softw...

This article presents the design and experimental validation of a 25-kW bidirectional DC/DC converter employing a dual DAB-CLLC resonant architecture to achieve high efficiency across an ultrawide 200–1000-V opera...

ABSTRACT Background Observational studies link insomnia to hippocampal atrophy, yet causal inference remains limited by confounding and reverse causality. While Mendelian randomization (MR) studies have explored sleep‐...

Objective This study aimed to assess the performance of time to maximum concentration (Tmax) using computed tomography perfusion for predicting stroke recurrence in patients with symptomatic non-acute atherosclerotic mid...

Understanding of thermodynamic variables in any binary liquid system is crucial for the development of industrial products. Among the various thermodynamic parameters, density (ρ), viscosity (η), surface tension (γ), ...

ABSTRACT This study examined acute vascular responses to three resistance training (RT) protocols differing in load and volume but matched for proximity to failure. Eleven adults (6 males and 5 females) performed three R...
