Centralization Trade-off with Non-Uniform Taxation [PDF]

When local public goods are provided by a centralized authority, spillovers are internalized, but heterogeneity in preferences may be suppressed. Besley and Coate (2003) recently examined this classic trade-off for a uniform tax regime with strategic ...

3D Coverage Optimization for WSNs Based on Improved Flow Direction Algorithm

Kongzhi Yu Xinxi Jishu
Traditional algorithms often struggle to address the issue of three-dimensional non-uniform coverage in Wireless Sensor Networks (WSNs). This paper presents a three-dimensional coverage optimization algorithm for WSNs, based on an improved flow direction

Predictive Ability of Plasma p‐tau217 for β‐Amyloid Status: A Prospective Multicenter Study

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Plasma tau phosphorylated at threonine 217 (p‐tau217) measured with fully automated platforms has shown high accuracy for Alzheimer's disease (AD) diagnosis, but real‐world multicenter data remain limited. We aimed to validate the diagnostic performance of p‐tau217 for identifying AD pathology in a real‐world multicenter cohort ...

On Certifying Non-Uniform Bounds against Adversarial Attacks [PDF]

This work studies the robustness certification problem of neural network models, which aims to find certified adversary-free regions as large as possible around data points. In contrast to the existing approaches that seek regions bounded uniformly along

Non-uniform stability for bounded semi-groups on Banach spaces

Journal of Evolution Equations, 2008
Let S(t) be a bounded strongly continuous semi-group on a Banach space B and – A be its generator. We say that S(t) is semi-uniformly stable when S(t)(A + 1)−1 tends to 0 in operator norm. This notion of asymptotic stability is stronger than pointwise stability, but strictly weaker than uniform stability, and generalizes the known logarithmic ...

Nexus Between Renewable, Non-Renewable, Nuclear Energy Consumption and Economic Growth in Five Developing and Developed Countries: A Cobb–Douglas Production Function Analysis

Energies
This paper estimates an extended Cobb–Douglas production function for five major economies (China, the EU, India, the Russian Federation, and the USA) over the period of 1990–2023, incorporating electricity production from renewable, non-renewable, and ...

Numerical solution for laminar unsteady flow about fixed and oscillating cylinders

Computer Assisted Methods in Engineering and Science, 2023
This paper presents a finite-difference solution of the two-dimensional, time dependent incompressible Navier-Stokes equations for laminar flow about fixed and oscillating cylinders placed in an otherwise uniform flow. Using boundary fitted coordinates,

Spatial and Volumetric Characteristics of Glioblastoma: Associations With Clinical Presentation and Survival

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective We aim to comprehensively analyze how regional tumor and edema characteristics are associated with clinical presentations and survival outcomes in a large cohort of glioblastoma patients. Methods Patients with IDH‐wildtype glioblastoma who received brain MRI from 2010 to 2023 were included.

Enhancing the quality of low-light images via the coefficient bounds derived for a subclass of Sakaguchi-type function

EURASIP Journal on Image and Video Processing
This paper introduces a new approach for enhancing low-light images by utilizing coefficient bounds from a specific subclass of analytic functions, a concept rooted in geometric function theory.

Neurochemical Endpoints to Inform Early‐Stage Trials of Spinocerebellar Ataxia 2 and 3 in a Multisite Setting

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Neurochemical levels measured by brain MR spectroscopy (MRS) have been proposed as endpoints for clinical trials in early‐stage spinocerebellar ataxia (SCA) trials. We tested their trial‐readiness by quantifying neurochemicals in three affected brain regions in early‐stage cohorts of SCA2 and SCA3, examining their reproducibility in ...
