Stochastic Gradient Descent in High Dimensions for Multi‐Spiked Tensor PCA

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We study the high‐dimensional dynamics of online stochastic gradient descent (SGD) for the multi‐spiked tensor model. This multi‐index model arises from the tensor principal component analysis (PCA) problem with multiple spikes, where the goal is to estimate the unknown signal vectors within the N$N$‐dimensional unit sphere through maximum ...

Energy Landscapes in Chemical Reactions and Transport

ChemPhysChem, Volume 26, Issue 6, March 15, 2025.
Kinetics/dynamics of chemical reactivity and transport of chemical species in a solid are both determined by the energy landscape in which they take place. Discussing common grounds but also distinct differences may help in advancing the understanding in both fields.

A Review of Virtual Twins in Physiologically‐Based Pharmacokinetic Modeling and Simulation

Clinical Pharmacology &Therapeutics, EarlyView.
The novel application of Virtual Twins (VT) in PBPK (VT‐PBPK) presents the opportunity to advance precision dosing and accelerate the shift from one‐size‐fits‐all to targeted, individualized treatments. This review aims to: (1) critically evaluate existing research on the use of VTs in PBPK, (2) develop a conceptual definition of VT‐PBPK, (3) describe ...

Prediction of Acute Liver Injury Trajectory in Patients Following Acetaminophen Overdose: A Multibiomarker Machine Learning Proof‐of‐Concept Study

Clinical Pharmacology &Therapeutics, EarlyView.
Clinical translation of novel therapies can be hindered by heterogeneity‐driven sample size inflation in late‐stage trials. In acetaminophen‐induced liver injury (APAP DILI), many patients recover spontaneously, diluting investigational drug efficacy signals.

Enhancing Knowledge and Technology Transfer: Determinants and Indicators of Successful University–Industry Collaboration

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Both universities and companies create value and innovation to maintain their position and remain competitive. Different, but still similar, with two goals that are shared. With their collaboration, they can enhance their pursuit of sustainability and as well corporate social responsibility by creating and delivering value and thus ...
