A hybrid numerical scheme for extended Boussinesq equations

Shui kexue jinzhan, 2013
To efficiently solve the extended Boussinesq equations,a hybrid finite-difference and finite-volume scheme is developed. The one-dimensional governing equations are kept in conservation form.

Influence of variable particle size reinforcement on mechanical and wear properties of alumina reinforced 2014Al alloy particulate composite [PDF]

FME Transactions, 2020
Al2O3 may be the most important reinforcement in aluminum-based composites that are rising quickly in modern years. The significance of this paper is to study the influence of Al2O3p size variation (i.e. 53 µm and 88 µm) and content (i.e. 9, 12, and 15Wt

Solution property preserving reconstruction for finite volume scheme: a boundary variation diminishing+multidimensional optimal order detection framework [PDF]

International Journal for Numerical Methods in Fluids, 2019
SummaryThe purpose of this work is to build a general framework to reconstruct the underlying fields within a finite volume (FV) scheme solving a hyperbolic system of PDEs (Partial Differential Equations). In an FV context, the data are piecewise constants per computational cell and the physical fields are reconstructed taking into account neighbor ...

Effect of mechanical alloying on sinterability and phase evolution in pressure-less sintered TiB2‒TiC ceramics

Journal of Materiomics, 2019
Phase relation and microstructure evolution in the pressure-less sintered TiB2‒TiC ceramics preceded with mechanical alloying were systematically studied by a combination of SEM analysis. WC debris from milling balls promotes sintering by dissolving into

Sign changes in linear combinations of derivatives and convolutions of Polya frequency functions

International Journal of Mathematics and Mathematical Sciences, 1979
We obtain upper bounds on the number of sign changes of linear combinations of derivatives and convolutions of Polya frequency functions using the variation diminishing properties of totally positive functions.

Natural Killer Cells in Paediatric Soft Tissue Sarcomas: A Systematic Review

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Paediatric soft tissue sarcomas (pSTS) are a rare and heterogeneous group of malignant tumours arising in tissues of mesenchymal origin. The role of natural killer (NK) cells in pSTS remains poorly understood, with evidence fragmented across small preclinical studies and early‐phase clinical trials.

Impact of Japan's 2024 Physician Work‐Style Reform on Pediatric Hematology–Oncology: Educational Implications in a 2‐Year Survey

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Japan's 2024 physician work‐style reform introduced legally binding limits on physicians’ working hours, but its impact on education and workforce sustainability in pediatric hematology–oncology (PHO) remains unclear. Procedure We conducted a repeated cross‐sectional study with structured quantitative items and free‐text responses ...

The planar cell polarity protein Vangl2 interacts with the PDZ‐domains of Scribble but not with a unique PDZ‐like domain in Inturned

FEBS Letters, EarlyView.
Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Variation diminishing properties of Bernstein polynomials on triangles

Journal of Approximation Theory, 1987
Let T be a triangle, \(f: T\to R\), \(B_ n(f,T)=Bn(f)\) the Bernstein polynomial of degree n and \(\{\hat f{}_ n\}\) the net of Bézier of order n for f on T. Let \(V(f,T)=\int_{T}(f^ 2_ x+f^ 2_ y)^{1/2} dT\) and \(V_ 1(f,T)=\int_{T}(f^ 2_{xx}+2f^ 2_{xy}+f^ 2_{yy})^{1/2} dT.\) Then the following results hold: 1) For any \(n\geq 1\) we have \(V_ 1(B_ n(f)
