Temperature-dependent electrical performance of β-Ga2O3 Schottky barrier diodes under 5 MeV proton irradiation

This work examines the effects of 5 MeV proton irradiation at a fluence of 1 × 10 13 cm −2 on the electrical characteristics of β-Ga 2 O 3 Schottky barrier diodes over a temperature range of 25 °C to 100 °C. Current–voltage (I-V), capacitance–voltage (C-V), and deep-level transie...

Patterns of smartphone-mediated digital engagement among pre-service teachers: A behavioural clustering approach to digital self-regulation

Smartphone use among students is usually studied through exposure measures such as screen time, which reveal little about how learners manage their digital engagement for academic purposes. This study identifies distinct patterns of smartphone-mediated digital engagement among pr...

Cascaded Delayed Signal Cancellation-Based Three-Phase Phase-Locked Loop for Enhanced Per-Phase Detection under Unbalanced Grid Conditions

This paper proposes an enhanced three-phase Phase-Locked Loop (PLL) algorithm based on Cascaded Delayed Signal Cancellation (CDSC) for accurate per-phase detection under unbalanced grid conditions. PLL is essential for extracting grid frequency and phase in grid-connected power c...

Political Economy Forecasts: The 2026 Midterms

We employ a political economy model to forecast the outcome of the 2026 midterm elections in the House and Senate.Earlier versions of our model have been utilized, to good effect, since 2010.The model draws on sound theory, which posits the importance of political and economic fu...

An Experimental Study on the Manoeuvrability of the KLNG2 with Different Speeds by Free Running Model Tests

This study evaluates the manoeuvring performance of the KRISO LNG carrier (KLNG2) using a 1/80 scale model in Free Running Model Tests (FRMT) at full-scale speeds of 5, 15, and 19.5 knots. The programme included 35° turning-circle and 10/10, 20/20 zigzag tests. Turning results sh...

STAR Protocols question-and-answer series: Flow cytometry

Flow cytometry is an integral part of the research scientist's toolbox. However, it is a complex methodology, involving decisions from antibody panel design to gating strategies to obtain the best results. Because it is so commonly used, there are many frequently asked questions...

Challenges and pathways for renewable energy transition amid crisis: A case study on community perspectives during the Russian war against Ukraine

The ongoing war in Ukraine has exposed the vulnerability of centralised energy systems while increasing the importance of decentralised renewable energy for maintaining essential public services. Existing research has largely focused on infrastructure damage, national energy poli...

Application and Performance Evaluation of a Physics-Informed Neural Network for Transformer Insulation Paper Degradation Prediction

Long-term operation of oil-immersed transformers degrades the internal insulation paper, making stable insulation performance difficult to maintain. This study evaluates a forward physics-informed neural network (PINN) for predicting the degree of polymerization (DP) of transform...

Prevalence of urinary incontinence among women in Turkey: A systematic review and meta-analysis

Urinary incontinence (UI), defined as the involuntary leakage of urine, is a common condition that affects women's quality of life and overall health. UI becomes more frequent with age and is also observed during pregnancy and postpartum. This systematic review and meta-analysis...

A Study on the Short Circuit Current Characteristics and Short Circuit Protection of ESS Battery

Energy Storage Systems store large amounts of electrical energy and may therefore supply high short circuit currents from the battery during a short circuit fault, requiring appropriate short circuit protection. In this study, the short circuit current characteristics of an ESS b...

Characterization of Polypropylene Degradation Induced by Dielectric Barrier Discharge

Polypropylene (PP) is widely used as an insulating material in high-voltage applications, and methods capable of inducing measurable degradation-related property changes within a short period are useful for evaluating material responses. In this study, atmospheric- pressure diele...

Field Measurement Based Estimation and Expansion of Hourly Charging Patterns of Personal Slow EV Chargers on Jeju Island

Personal slow chargers account for 83.4 % of all EV chargers on Jeju Island, yet their hourly charging behavior is unobservable because these units have no communication capability and utility metering records only monthly energy by time of use (TOU) period. This paper presents a...

PV-ESS Integrated Operation Analysis of a Major Railway Station Based on Measured Load: 15-min Peak Demand and Time-of-Use Tariff

Railway stations run continuously with flat, base-load-dominated electricity demand, so the value of photovoltaics (PV) and energy storage (ESS) differs from buildings with daily peaks. This study analyzes PV-ESS integrated operation for SRT station using twelve months of metered...

Analysis of the Cost Impact of Pre-Clustering Methods on Inter-Array Network Optimization in Offshore Wind Farms with Multiple OSS(offshore substation)s

This paper analyzes the effect of pre-clustering methods on inter-array network optimization in offshore wind farms with multiple offshore substations (OSSs). A binary integer programming (BIP)-based model is used to compare integrated optimization with distance-based and angle-b...

Nonlinear response of soil moisture drought persistence to climatic aridity at the global scale

Soil moisture deficit persistence affects drought development, ecosystem resilience, and land–atmosphere feedbacks, but its dependence on climatic aridity is still not well understood at the global scale. We examine whether persistence changes gradually along the aridity gradient...

Mechanical pump shaft seals: Dynamic stability and dynamic sealing considerations

The majority of power reactor designs utilize pumps to circulate the primary coolant past the fuel to transfer heat away and provide the thermal power to generate electricity. Mechanical shaft seals are critical nuclear components used to prevent leakage between a rotating pump s...
