Piezoelectric and thermal strain in AlGaN/GaN-based HEMTs in operation

Marius Holger WETZEL · Carsten RICHTER (ORCID: 0000-0002-4230-215X) · Dina SHEYFER · Ugwumsinachi OJI · y 2 más

We propose to acquire operando scanning X-ray diffraction microscopy (SXDM) maps on Al(Ga)N/GaN-based HEMT devices in operation mode. The study aims to probe the lattice distortion in the active layer of the device due to inhomogeneities in the electric field and temperature distribution. The results will help to bench...

On a stochastic phase-field model of cell motility with singular diffusion

Amjad Saef · Wilhelm Stannat

We study existence of solutions in the variational sense for a class of stochastic phase-field models describing moving boundary problems. The models consist of stochastic reaction-diffusion equations with singular diffusion forced by a phase-field. We investigate both the case of an independently evolving phase-field...

Exosomes in brain diseases: Mechanisms, advances, and perspectives

Qinzhen Cheng · Yalan Zhu · Shiwen Lv · Rudong Chen · y 2 más

The blood-brain barrier (BBB) remains a major biological obstacle limiting the effective delivery of therapeutics for central nervous system (CNS) disorders. Although conventional drug delivery approaches have achieved continuous advances, their clinical translation is frequently restricted by limited brain penetration...

Local and electronic mechanisms of the 7-fold coordination transition in “metallic” WO3

JOAO ELIAS FIGUEIREDO SOARES RODRIGUES · Yimin MIJITI · Luís Fernando DA SILVA · Ariadne Cristina CATTO SILVA · y 1 más

Our goal is to probe the densification transition, local structure mechanisms, and electronic evolution of both amorphous WO3 and crystalline 7-coordinated “metallic” WO3, using XAS under high-pressure conditions. Amorphous (a) and crystalline (c) WO3 present distinct electronic properties, which are mainly concerned t...

Speckle-Based Dark Field at the Nanoscale

Kim BAZOT · Clara MAGNIN · Julie VILLANOVA · Simon RIT · y 6 más

X-ray nanoscopy is an imaging approach that is expected to provide numerous answers regarding the structure of matter at the molecular level. Full-field X-ray imaging can reach such resolution if the setup is combined with strongly focusing optics capable of generating the desired magnification. In this kind of imaging...

Establishing the Role of Hydrogen in Metal Plasticity

Sara IRVINE · Yaozhu LI (ORCID: 0000-0002-9092-659X) · Brinthan KANESALINGAM · Leora DRESSELHAUS-MARAIS · y 2 más

Hydrogen (H) is essential to decarbonize industry, but its use today is limited because it embrittles the metals and alloys required to store/distribute it. Despite 150 years of research, the fundamental mechanisms of H-embrittlement are still poorly understood. H atoms form a solid solution of interstitials in structu...

Serial (SSX): Southampton, Bristol, Essex, Exeter, KCL, Leicester Block Allocation Group (BAG)

Jack STUBBS · Samuel ROSE · Lewis WILLIAMS · Ivo TEWS · y 2 más

The BAG coordinates work in serial synchrotron crystallography, SSX. We propose to collect low dose ground states on enzymes, ligand complexes, and redox sensitive metallo-proteins, using the fixed target chip or foil sample delivery systems at ID29. For time resolved work, we propose laser activated work as well as mi...

Masked generative-contrastive representation learning for cross-dataset EEG-based emotion recognition

Huqin Weng · Jiayang Huang · Yimin Wen · Jie Du · y 2 más

Self-supervised learning (SSL) shows strong potential for cross-dataset transfer by improving feature representation and generalization. However, its application to EEG-based emotion recognition remains largely unexplored. Existing SSL methods struggle to capture the intricate spatiotemporal dependencies of EEG signals...

Inferring network-level alarm influence pathways for cellular infrastructure reliability

Cai, Xiao · Mukherjee, Anandarup · Wang, Qiqi · Parekh, Arjun · y 2 más

Large-scale telecommunication infrastructure, such as Radio Access Networks (RANs), is a critical component of the modern digital industry. To ensure infrastructure intelligence and operational reliability, it is essential to understand how alarms influence one another across base stations. Existing alarm analysis appr...

Echo state networks for time series forecasting: Hyperparameter sweep and benchmarking

Alexander Häußer

This paper investigates the performance of Echo State Networks (ESNs) for univariate forecasting of monthly and quarterly time series from the M4 Forecasting Competition dataset. We evaluate whether a simple first-order autoregressive ESN can serve as a competitive alternative to widely used forecasting methods. The st...
