Test of modified BCS model at finite temperature

open access: yes, 2005
A recently suggested modified BCS (MBCS) model has been studied at finite temperature. We show that this approach does not allow the existence of the normal (non-superfluid) phase at any finite temperature.

Testing Conditional Factor Models [PDF]

open access: yesSSRN Electronic Journal, 2009
We develop a new methodology for estimating time-varying factor loadings and conditional alphas based on nonparametric techniques. We test whether long-run alphas, or averages of conditional alphas over the sample, are equal to zero and derive test statistics for the constancy of factor loadings. The tests can be performed for a single asset or jointly

Student Withdrawal: Test of an Integrated Model [PDF]

open access: yes, 2000
This study examined a model of student withdrawal that integrated the major elements of Tinto\u27s (1975) Student Integration Model and Bean\u27s (1982, 1983) Industrial Model of Student Attrition.

European Standard Clinical Practice Guideline and EXPeRT Recommendations for the Diagnosis and Management of Gastroenteropancreatic Neuroendocrine Neoplasms in Children and Adolescents

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Pediatric gastroenteropancreatic neuroendocrine neoplasms (GEP‐NENs) are extremely rare and clinically heterogeneous. Management has largely been extrapolated from adult practice. This European Standard Clinical Practice Guideline (ESCP), developed by the EXPeRT network in collaboration with adult NEN experts, provides (adult) evidence ...

A test for model specification of diffusion processes

open access: yes, 2008
We propose a test for model specification of a parametric diffusion process based on a kernel estimation of the transitional density of the process. The empirical likelihood is used to formulate a statistic, for each kernel smoothing bandwidth, which is ...

Why and When Are Evidence‐Based Interventions Adopted in Paediatric Supportive Care? A Qualitative Exploration of the Determinants of Photobiomodulation Implementation

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background Oral mucositis is a common and debilitating side effect of childhood cancer and stem cell transplant treatments. It affects the quality of life of children and young people (CYP) and places a strain on services. Photobiomodulation is recommended for oral mucositis prevention in international guidance but is poorly implemented in UK ...

Experimental Study on Dynamic Responses of Floating Offshore Wind Turbines and Its Validation Against the Vector-Form Intrinsic Finite Element Method

open access: yesJournal of Marine Science and Engineering
In this study, a novel rigid–flexible coupled computational model for floating offshore wind turbines (FOWTs) is developed using the vector-form intrinsic finite element (VFIFE) method, named VFIFE-FOWT.

Parameter optimization design of stern flap of displacement surface warship

open access: yesZhongguo Jianchuan Yanjiu, 2019
[Objectives]The design of stern flap usually focuses on resistance reduction at high speed. For surface warship stern flap design which is aimed at optimizing the cruise speed and design speed,the cruise speed comes in a large range,so the parameter ...

Experimental Investigation of Dynamic Response of Pile-Supported Wharf in Liquefiable Ground Under Wave Action

open access: yesShanghai Jiaotong Daxue xuebao, 2023
Pile-supported wharf (PSW) is widely used in the deep-water port engineering construction, most of which are located in liquefiable ground. The effect of wave action on the working performance of PSW in liquefiable ground cannot be ignored, but few ...

Upward Influence in Organizations: Test of A Model [PDF]

open access: yes, 1990
A causal model of upward influence in organizations was proposed and tested on a sample of staff nurses and their supervisors in a hospital setting. LISREL results demonstrated that the proposed model fit the data well, and reflected a better fit than ...
