Meshless methods: theory and application in 3D fracture modelling with level sets [PDF]

, 2010
Accurate analysis of fracture is of vital importance yet methods for effetive 3D calculations are currently unsatisfactory. In this thesis, novel numerical techniques are developed which solve many of these problems. This thesis consists two major parts:

Level of Vascular Ligation for Sigmoid Colon Cancer: Does It Matter? The Pina Low‐T Study

Journal of Surgical Oncology, EarlyView.
ABSTRACT Background and Methods In sigmoid colon cancer surgery, the inferior mesenteric artery (IMA) can be ligated at its origin (high ligation, HLG) or distal to the left colic artery bifurcation (low ligation, LLG). While high ligation facilitates lymph node harvest and mobilization, it may compromise colonic perfusion and increase nerve injury ...

Juvenile Mycosis Fungoides: A Multicenter Retrospective Italian Study

JEADV Clinical Practice, EarlyView.
This multicenter retrospective study included 29 juvenile mycosis fungoides (JMF) patients from five Italian centres with confirmed histopathological diagnosis. most often presents with hypopigmented/classic variants and CD8+ phenotype. Early‐onset cases ( < 14 years) show better long‐term outcomes.

Heterogeneity Analyzed by CT‐Based Habitat Analysis for Clinical Management of Cancers: A Narrative Review

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Tumors are highly heterogeneous, and whole‐lesion radiomics analysis is a popular method for extracting texture features that reflect this heterogeneity, which can be used to build models for cancer diagnosis, staging, therapy response evaluation, and prognosis prediction.

Variational derivation of the simplified P(2) nodal approximation.

, 1994
In order to develop models that contain more accurate transport physics than standard P$\sb1$ theory, researchers have developed higher-order P$\sb{\rm N}$ methods, which are based on spherical-harmonic expansions of the unknown angular flux of neutrons.

Variational Multiscale Finite Element Method Based on Bubble Element for Steady Advection-Diffusion Equations

This paper presents a variational multiscale (VMS) finite element method based on the bubble element, which enables the establishing of a multiscale function to stabilize the advective-diffusive limit and the discontinuity in steady advection-diffusion ...

Robust Position Control of an Electro‐Hydraulic Actuator via Metaheuristic Optimization of a Fractional‐Order PID Controller

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT In this study, a robust position control strategy is presented for a two‐stage electro‐hydraulic actuator system using a fractional‐order proportional–integral–derivative (FOPID) controller tuned by Kirchhoff's law algorithm (KLA). Electro‐hydraulic systems exhibit strong nonlinearities, parameter uncertainties, and external disturbances ...

Ultrasound‐Confirmed Median Nerve Pseudoconduction Block due to Anatomical Variation

Muscle &Nerve, EarlyView.
ABSTRACT Introduction/Aims Conduction block (CB) at non‐entrapment sites is an important electrodiagnostic (EDX) feature supporting acquired demyelinating neuropathies. However, anatomical variation may produce pseudoconduction block, mimicking true CB.

A Coupled Extended Finite Element–Cohesive Zone Model for Hydraulic Fracture Propagation Under Poroelastic Effects Across Different Propagation Regimes

International Journal for Numerical and Analytical Methods in Geomechanics, EarlyView.
ABSTRACT Numerical simulation of hydraulic fracturing remains challenging due to the strong coupling between geomechanics and fluid flow when modelling multiple physical mechanisms of rock deformation, fracture evolution and fluid leak‐off. This study develops a coupled hydraulic fracture propagation framework that combines the extended finite element ...
