Study of Phase Stability in NiPt Systems

open access: yes, 2003
We have studied the problem of phase stability in NiPt alloy system. We have used the augmented space recursion based on the TB-LMTO as the method for studying the electronic structure of the alloys.

Thermodynamic Instability of Black Holes of Third Order Lovelock Gravity

open access: yes, 2009
In this paper, we compute the mass and the temperature of the uncharged black holes of third order Lovelock gravity and compute the entropy through the use of first law of thermodynamics.

Phase models and clustering in networks of oscillators with delayed coupling [PDF]

open access: yes, 2016
We consider a general model for a network of oscillators with time delayed, circulant coupling. We use the theory of weakly coupled oscillators to reduce the system of delay differential equations to a phase model where the time delay enters as a phase ...

Phase Stability of Concentrated Dairy Products [PDF]

open access: yesJournal of Dairy Science, 2003
The interactions between the two most important colloids in milk, fat globules and casein micelles, were investigated. Mixtures of oil droplets (as a model for fat globules) and casein micelles were prepared, and their phase behavior was studied.

Stability of solitons in time-modulated two-dimensional lattices

open access: yes, 2017
We develop stability analysis for matter-wave solitons in a two-dimensional (2D) Bose-Einstein condensate loaded in an optical lattice (OL), to which periodic time modulation is applied, in different forms.

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Alloy phase stability

open access: yes, 1987
The calculation of phase diagrams from first principles constitutes a critical test of accuracy of both quantum and statistical mechanical models. The slightest variation of calculated energies can result in drastic changes in the topology of phase diagrams: the location of phase boundaries and even the nature of the phases in mutual equilibrium is ...

The formation of sigma phase in the CoCrFeNi high-entropy alloys

open access: yesMaterials Research Express, 2021
The as-cast CoCrFeNi high-entropy alloys show simple FCC structure and outstanding deformation ability at room temperature. Respectively, after 50% of deforming at room temperature and annealing at intermediate temperature range of 600 °C–800 °C for 2 h,

Phase stability and polymorphism of a new naproxen salt

open access: yesBritish Journal of Pharmacy, 2023
We report on the synthesis and structural characterization of a new naproxen salt. In-situ heating X-ray diffraction experiment allows us to determine the phase stability of the various polymorphic phases.

Stability of phase retrievable frames [PDF]

open access: yesSPIE Proceedings, 2013
In this paper we study the property of phase retrievability by redundant sysems of vectors under perturbations of the frame set. Specifically we show that if a set $\fc$ of $m$ vectors in the complex Hilbert space of dimension n allows for vector reconstruction from magnitudes of its coefficients, then there is a perturbation bound $ $ so that any ...
