Journal: :The wrongful conviction law review 2023

We analyzed the role that jailhouse informants have played in DNA exoneration cases. Thus, for first 375 cases compiled by Innocence Project (IP), we reviewed IP information relevant to informant testimony. supplemented from with National Registry of Exonerations (NRE) and Convicting Innocent (CTI) databases. found 15% these included In 13% cases, only evidence supporting a conviction was word ...

Abstract: nanocrystalline nickel samples with the grain size of ~25 nm were prepared via direct current electrodeposition andaluminized for different durations by pack cementation method at 500 means of SEM, EDS and XRD techniques. According to results, short time aluminizing resulted in the formation of asingle aluminide layer whereas at long duration two distinct aluminide layers were formed....

In this paper, for the numerical approximation of random partial differential equations (RPDEs) of parabolic type, an explicit higher order finite difference scheme is constructed. In continuation the main properties of deterministic difference schemes, i.e. consistency, stability and convergency are developed for the random cases. It is shown that the proposed random difference scheme has thes...

In stochastic volatility models, European option prices are solutions to parabolic differential equations. In this paper we propose a finite difference scheme for solving these equations numerically. We prove the stability and convergence of this method in norm infinity. Then we use the ADL method to separate the operators, this allows us to apply Thomas algorithm to solve the corresponding lin...

Following Parreau’s work in 1951-52, we give a unified definition of parabolic Riemann surfaces, with or without boundary. A surface is parabolic under the unified definition implies that it is either relative parabolic or parabolic under the classical definitions. Then we study the conformal structures of noncompact, proper, branched minimal surfaces in R and prove several criteria of such sur...

Recently there are so many mathematical models which describe nonlinear phenomena. In some phenomena, the free energy functional is not convex. So, the existence-uniqueness question is sometimes difficult. In order to study such phenomena, let us introduce the new class of abstract nonlinear evolution equations governed by timedependent operators of subdifferential type. In this paper we shall ...

We establish new convergence results, in strong topologies, for solutions of the parabolic-parabolic Keller–Segel system in the plane, to the corresponding solutions of the parabolic-elliptic model, as a physical parameter goes to zero. Our main tools are suitable space-time estimates, implying the global existence of slowly decaying (in general, nonintegrable) solutions for these models, under...

Recently, increase in the cost of fossil fuels and taking into consideration the environmental effects of exploiting them, caused many researchers and governments to find some ways to make use of renewable energies more cost-effectively. Solar energy is a category of renewable energies which could be harvested via several technologies. One of the most practical methods is using parabolic trough...

A common thread in the circular economy literature is linear–circular contrast. This study shows that has always been a mix of and linear applications but varying proportions. Furthermore, scrutiny emblematic examples both reveals misconceptions enriches extant knowledge frameworks their relationship. also explains which aspects encourage an to lean towards either or (i.e., profit, scarcity, ci...

We present a corrected operator splitting (COS) method for solving nonlinear parabolic equations of convection-diiusion type. The main feature of this method is the ability to correctly resolve nonlinear shock fronts for large time steps, as opposed to standard operator splitting (OS) which fails to do so. COS is based on solving a conservation law for modeling convection, a heat type equation ...
