Stable Numerical Solution of an Elliptic PDE Inverse Problem Subject to Incomplete Boundary Conditions

Wasit Journal of Computer and Mathematics Science
This paper addresses the inverse problem of reconstructing complete steady-state solutions for elliptic partial differential equations when boundary information is incomplete a situation common in electromagnetic, thermal, and geophysical modeling where ...

Hölder stability for a semilinear elliptic inverse problem

Journal of Mathematical Analysis and Applications
We are concerned with the problem of determining the nonlinear term in a semilinear elliptic equation by boundary measurements. Precisely, we improve [5, Theorem 1.3], where a logarithmic type stability estimate was proved. We show actually that we have Hölder stability estimate with less boundary measurents and less regular nonlinearities.

The Coloniality of Data: Police Databases and the Rationalization of Surveillance from Colonial Vietnam to the Modern Carceral State

The British Journal of Sociology, EarlyView.
ABSTRACT Tracing the early adoption of computer gang databases by the Los Angeles County Sheriff's Department and the Los Angeles Police Department in the 1980s to the deployment of computationally‐assisted surveillance during the Vietnam War, this paper uses a genealogical approach to compare surveillance technologies developed across the arc of ...

Multifactorial determinants of male genital measurements: Correlations of stretched penile length and anogenital distance with anthropometric parameters

Andrology, EarlyView.
Abstract Background The stretched penile length is recognized as the most reliable measure of true penile size, this fact is not widely acknowledged, and societal myths often associate penile length with other anthropometric measurements. While markers of prenatal androgen exposure, such as anogenital distance and the second‐to‐fourth digit ratio (2D ...

Association of bi‐parametric MRI measures with continence after robot‐assisted radical prostatectomy

BJU International, Volume 135, Issue 4, Page 603-610, April 2025.
Objective To investigate the association between pre‐ and postoperative magnetic resonance imaging (MRI) measurements of the membranous urethra and the prostate volume and continence following robot‐assisted radical prostatectomy (RARP). Patients and Methods From December 2018 to June 2022, 100 continent patients undergoing unilateral nerve‐sparing or ...

Calibrating Bayesian inference

British Journal of Mathematical and Statistical Psychology, EarlyView.
Abstract Bayesian statistics has gained popularity in psychological research due to its intuitive uncertainty quantification and convenient information‐updating rules. In many applications, however, prior distributions are introduced merely as instruments to facilitate computation, rather than as representations of genuine subjective belief ...

Splatshop: Efficiently Editing Large Gaussian Splat Models

Computer Graphics Forum, EarlyView.
Abstract We present Splatshop, a highly optimized toolbox for interactive editing (selection, deletion, painting, transformation, …) of 3D Gaussian Splatting models. Utilizing a comprehensive collection of heuristic approaches, we carefully balance between exact and fast rendering to enable precise editing without sacrificing real‐time performance. Our

TABI: Tight and Balanced Interactive Atlas Packing

Computer Graphics Forum, EarlyView.
Abstract Atlas packing is a key step in many computer graphics applications. Packing algorithms seek to arrange a set of charts within a fixed‐size atlas with as little downscaling as possible. Many packing applications such as content creation tools, dynamic atlas generation for video games, and texture space shading require on‐the‐fly interactive ...

A Splitting Architecture for Exact Reduced Coulomb Friction

Computer Graphics Forum, EarlyView.
Abstract Existing approaches to frictional contact dynamics typically either modify the Coulomb law to improve numerical robustness or solve the exact law in a fully coupled monolithic form. However, in its reduced form, exact Coulomb friction can be written as a cone complementarity problem with an augmented velocity, which reveals a natural split ...

Anisotropic inverse problems for quasilinear elliptic equations

Journal of Physics: Conference Series, 2005
In this paper we discuss inverse boundary value problems for quasilinear elliptic equations in connection with the nonlinear conductivity problem and inverse problems in nonlinear material sciences.
