Effects of Wall‐to‐Floor Interactions on Seismic Response of Platform‐Type CLT Buildings

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Platform‐type cross‐laminated timber (CLT) buildings feature discontinuous wall segments supported by CLT floors. In practice, CLT floors are often treated as rigid diaphragm, yet the wall‐to‐floor interactions (WFIs) associated with flexibility of floors remain insufficiently investigated during seismic performance assessment.

Stability Evaluation and Parametric Optimization of Coal‐Concrete Composite Bearing Systems Under Mine‐Water‐Induced Deterioration: Experiments and FEINN Analysis

Energy Science &Engineering, EarlyView.
Mine‐water immersion tests reveal pronounced coal weakening (vs. minor concrete degradation), identifying coal pillars as the stability‐limiting component in composite dams. A coupled FEINN framework quantifies extreme‐pressure stability and ranks multi‐parameter designs via a normalized multi‐indicator scheme, enabling optimized dam configuration for ...

Oddness of least energy nodal solutions on radial domains

Electronic Journal of Differential Equations, 2010
In this article, we consider the Lane-Emden problem $$displaylines{ Delta u(x) + |{u(x)}mathclose|^{p-2}u(x)=0, quad hbox{for } xinOmega,cr u(x)=0, quad hbox{for } xinpartialOmega, }$$ where $2 < p < 2^{*}$ and $Omega$ is a ball or an annulus

Nodal variational principle for excited states

, 2018
It is proven that the exact excited-state wave function and energy may be obtained by minimizing the energy expectation value of trial wave functions that are constrained only to have the correct nodes of the state of interest.

PMU‐Based Wide Area Monitoring With Machine Learning to Prevent Blackouts in Bangladesh Power System

Energy Science &Engineering, EarlyView.
A Unified Real‐time Dynamic State Measurements (URTDSM) system with PMU and Phasor Data Concentrator (PDC) deployment plan has been proposed to avoid blackout in the Bangladeshi power system. Machine learning has been used to process data from PMU to identify abnormal events. ABSTRACT The electrical power system must be trustworthy and secure enough to

Dynamic multi‐objective optimisation of complex networks based on evolutionary computation

IET Networks, EarlyView., 2022
Abstract As the problems concerning the number of information to be optimised is increasing, the optimisation level is getting higher, the target information is more diversified, and the algorithms are becoming more complex; the traditional algorithms such as particle swarm and differential evolution are far from being able to deal with this situation ...

Space-angle approximations in the variational nodal method.

, 1999
The variational nodal method is formulated such that the angular and spatial approximations maybe examined separately. Spherical harmonic, simplified spherical harmonic, and discrete ordinate approximations are coupled to the primal hybrid finite element

Anatomical Understanding and Evolution of Surgical Treatment for Cancer of the Esophagogastric Junction: From Anatomical Controversies to Precision Surgery

Gut Medicine, EarlyView.
ABSTRACT The incidence of cancer of the esophagogastric junction (EGJC) has surged globally. Historically, its unique anatomical position and dual histological characteristics generated significant controversy regarding tumor classification and surgical strategies.

Incidence and Site‐Specific Risk Factors of Jaw Osteoradionecrosis for Head and Neck Patients in the IMRT/VMAT Era: Evidence From a Large, Hospital‐Based Cohort

Head &Neck, EarlyView.
ABSTRACT Purpose Osteoradionecrosis (ORN) of the jaw remains a serious late complication of head and neck cancer (HNC) radiotherapy. Although intensity‐modulated radiotherapy (IMRT) and volumetric‐modulated arc radiotherapy (VMAT) are expected to reduce ORN risk, large real‐world data in the modern era are limited.

External Validation of Pre‐Treatment Primary Tumor Volume as a Prognostic Factor in Head and Neck Cancer Treated With (Chemo)Radiotherapy

Head &Neck, EarlyView.
ABSTRACT Background Primary tumor volume (GTVp) is a key prognostic factor in oropharyngeal squamous cell carcinoma (OPSCC) treated with radiotherapy. We aimed to externally validate this association and assess its relevance in other head and neck sites.
