Context‐free graphs and their transition groups
Abstract Starting from context‐free inverse graphs, we introduce a new class of groups and study their structural properties. We establish closure properties, show that their coword problems are context‐free, analyze torsion elements, and realize them as subgroups of the asynchronous rational group.

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

Do Androids Dream of Electric Sheep? A Psychoanalytic Inquiry Into Large Language Models
ABSTRACT Large language models produce fluent, contextually appropriate language that invites the inference that something behind the output is thinking. The psychoanalytic theory of thinking, specifically the work of Wilfred Bion and Donald Winnicott read together, allows us to specify what thinking requires, what the LLM lacks, and what occurs when a

Deep Spatially Varying Coefficient Model for Interpolation of Non‐Stationary Meteorological Data
ABSTRACT In spatial statistics, the spatially varying coefficient model (SVCM) is widely applied in the analysis and interpolation of non‐stationary spatial data. By incorporating spatially varying coefficients, the model can capture spatial heterogeneity and provide an attractive interpretation of response‐covariate associations.

ABSTRACT Due to their superior load density, planetary gear journal bearings (PGJB) are progressively replacing rolling element bearings in wind turbine gearboxes; therefore, accurately revealing the dynamic characteristics of drivetrains supported by these bearings under variable operating conditions is crucial for ensuring operational reliability ...

ABSTRACT Electrical and Computer Engineering (EE/CE) education encompasses the rigorous study of electronic systems, computing architectures, embedded platforms, signal processing and hardware–software integration. Its inherently multidisciplinary nature demands mastery of mathematical modelling and experimental validation skills that pose substantial ...
