TCAD Simulations of Degradation Mechanism in p-GaN Gate HEMTs under Gate Stress

2026 IEEE International Reliability Physics Symposium (IRPS)
In this paper we perform physical simulations of p-GaN gate HEMTs to study the time-dependent-gate-breakdown (TDGB) phenomenon when subject to constant-voltage stress (CVS). Leveraging on the advanced capabilities of Ginestra TCAD software, we show for the first time a simulation methodology able to model and explain the onset of gate breakdown ...

Passenger variants as pan‐clonal markers of pediatric AML: Implications for molecular MRD

HemaSphere, Volume 10, Issue 8, August 2026.
Abstract A streamlined, sensitive, and universal molecular method for MRD detection in pediatric AML remains an unmet clinical need. Here, we propose a novel approach based on tracking somatic non‐coding passenger variants. Using whole‐genome sequencing (WGS) of diagnostic bone marrow DNA, we identify patient‐specific somatic passenger variants, which ...

Knowledge‐distilled diffusion models for improving cone‐beam CT image quality with meta‐learning under imbalanced data

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Adaptive radiation therapy (ART) relies on daily cone‐beam CT (CBCT), yet its limited image quality hinders accurate dose calculation, particularly under substantial anatomical changes. Purpose To overcome the clinical challenge of scarce paired planning CT (pCT) data versus abundant unpaired CBCTs, we propose a framework driven by ...

Equivariant conditional diffusion model for head and neck CT image synthesis from CBCT

Medical Physics, Volume 53, Issue 8, August 2026.
Abstract Background Cone‐beam computed tomography (CBCT) is a commonly used modality for image guided radiotherapy (IGRT). It offers real time anatomical visualization with low acquisition cost and dose. Nevertheless, photon scattering and beam hindrance lead CBCT images to suffer from several artifacts.

Cascading River‐Lake Hydrological Regulation Reshapes Carbon Budgets of Floodplain Lakes in the Yangtze River Basin

Earth's Future, Volume 14, Issue 8, August 2026.
Abstract The carbon budget of floodplain lakes is regulated by natural hydrological processes, yet the role of human interventions, including cascade river‐lake hydraulic projects, remains unclear. We evaluated the combined effects of the Three Gorges Dam (TGD) located on the Yangtze River and the proposed lake‐specific hydraulic projects (LHPs) on the

Bidirectional Energy Transfer via Simultaneous Wave‐Particle Resonances in Inhomogeneous Space Plasmas

AGU Advances, Volume 7, Issue 4, August 2026.
Abstract Wave‐particle resonance is a key mechanism for energy transfer in collisionless plasmas with important implications for wave excitation and particle acceleration. Cyclotron resonance occurs when a particle's gyromotion synchronizes with the wave fields, with their interactions usually describable by quasilinear diffusion or nonlinear trapping.

Taming the Heterogeneous Dynamics of Oceanic Chlorophyll‐a Concentration With a Novel Deep Learning Model to Improve Prediction

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Chlorophyll‐a (Chl_a) concentration in the ocean is a critical indicator of primary production and plays a pivotal role in the global carbon cycle. Its accurate predictions are essential for reliable projections of future climate change. However, Chl_a is controlled by myriads of interactive physical and biogeochemical processes, posing a ...

Disentangling Spatial‐Temporal Features for Controllable Factors Learning in Precipitation Nowcasting

Journal of Geophysical Research: Machine Learning and Computation, Volume 3, Issue 4, August 2026.
Abstract Precipitation nowcasting refers to the high‐resolution forecasting of rainfall and hydrometeors within 0–6 hr according to the official definition of the World Meteorological Organization, which has relied on numerical models for decades. Recently, artificial intelligence (AI) has shown promise in addressing precipitation nowcasting.
