Fatigue Crack Growth in Complex Stress Fields [PDF]

open access: yes, 2008
Fatigue crack growth has been traditionally modelled using LEFM through the use of the Paris law. This requires an accurate method for stress intensity factor (K) calculation. Weight functions have been developed for one-dimensional cracks (e.g.

Diagnostic weight functions in constants-of-motion phase-space

open access: yesNuclear Fusion
The fast-ion phase-space distribution function in axisymmetric tokamak plasmas is completely described by the three constants of motion: energy, magnetic moment and toroidal canonical angular momentum. In this work, the observable regions of constants-of-

Recursive weights for some Boolean functions

open access: yesJournal of Mathematical Cryptology, 2012
This paper studies degree 3 Boolean functions in n variables which are rotation symmetric, that is, invariant under any cyclic shift of the indices of the variables.

On a Certain Weighted Partition Function [PDF]

open access: yesProceedings of the American Mathematical Society, 1950
Verf. betrachtet von dem in einer früheren Arbeit behandelten Problem [Proc. Am. Math. Soc. 1, 182--191 (1950; Zbl 0037.16903)] den Spezialfall, wo \(\gamma(n)\) die Funktion \(\Lambda(n)\) aus der Primzahltheorie ist. Durch Anwendung der Mellinschen Formel erhält man \[ \log g(s) = -\frac1{2\pi i} \int_{3/2-i\infty}^{3/2+i\infty} \Gamma(z) s^{-z ...

Establishing an Apheresis Medicine Program in a Resource‐Constrained Setting: A 5‐Year Experience From Lagos, Nigeria

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Establishing a comprehensive apheresis medicine program in a resource‐constrained setting presents significant structural, financial, and logistical challenges. Despite the growing clinical importance of apheresis services globally, published experience from sub‐Saharan Africa remains sparse.

Non-real eigenvalues of symmetric Sturm–Liouville problems with indefinite weight functions

open access: yesElectronic Journal of Qualitative Theory of Differential Equations, 2017
The present paper deals with non-real eigenvalues of regular Sturm–Liouville problems with odd symmetry indefinite weight functions applying the two-parameter method.

Comparative Evaluation of Hemodiafiltration, Hemoperfusion, and Standard Hemodialysis on Efficacy, Inflammatory Control, Dialysis Adequacy, and Safety in End‐Stage Renal Disease: A Prospective Observational Study

open access: yesTherapeutic Apheresis and Dialysis, EarlyView.
ABSTRACT Background Chronic micro‐inflammation in patients with end‐stage renal disease (ESRD) is a significant driver of cardiovascular complications and diminished quality of life. While standard hemodialysis (SHD) effectively manages small‐molecule clearance, its ability to remove medium‐to‐large uremic toxins—the primary catalysts of systemic ...

Body Weight as a Motivating Operation: The Effect of Body Weight on Demand for Food in Hens. [PDF]

open access: yes, 2014
Demand for wheat and puffed wheat was examined in six hens, using an ascending geometric progression of fixed-ratio schedules of reinforcement. Hens responded by pecking a key for 2-s access to food in 40-min sessions.

On weight functions admitting Chebyshev quadrature [PDF]

open access: yes, 1987
In this paper we prove the existence of Chebyshev quadrature for three new weight functions which are quite different from the two known examples given by Ullman [15] and Byrd and Stalla [2]. In particular, we indicate a simple method to construct weight
