On (J - Δ) Semi Homogeneous Systems Of Differential Equations, Aya H. Hasan, Bassam Jabbar Al-Asadi

Baghdad Science Journal

The concept of homogeneity in differential equations can be generalized to systems of differential equations as shown in this work. The classification of three-dimensional differential equation systems is presented based on the definition of the Jacobean matrix and its determinant, where two systems of the homogeneous system are defined, called the J-semi-homogeneous system and the other δ-semi-homogeneous system, where the first definition is based on the Jacobian matrix, while the second is based on the determinant of the Jacobite matrix. Examples are given for both definitions, and the relationship between the two definitions will be studied. In addition to finding …

This research proposes a mathematical model to investigate the dynamical behavior of the system of three species, namely prey, predator and top predator. The feeding behavior of each predator serves as a functional response. The interaction between the species is carried out by a functional response. Crowley Martin functional response is incorporated between prey and predator while Holling type III functional response occurs between predator and top predator. The existence of positivity and boundedness of the system have been examined. The equilibrium points of the system are determined. The system has been linearized by applying the Jacobian matrix. The main …

New Approximating Results By Weak Convergence Of Forked Sequences, Bareq Baqi Salman, Salwa Salman Abed

Baghdad Science Journal

The modular function spaces are natural generalization of spaces like Lebesgue space, Orlicz space, Lorentz p-space, Orlicz--Lorentz space, Musielak--Orlicz space, et al. The function modulars lack basic and flexible properties that norm functions have, as they are functional lacks homogeneity and subadditivity and, therefore, it might be surprising to use techniques involving asymptotic centers, normal structure and uniform convexity to obtain fixed point theorems. The purpose of this paper is to give a new accelerated iterative algorithm for multi valued\single valued mappings in modular function spaces and to prove some results about their convergence (strong or weak) to a fixed …

Hopf And Zero-Hopf Bifurcation Of The Four-Dimensional Lotka-Volterra Systems, Sirwan A. Mustafa, Niazy H. Hussen

A Natural Law Approach To Parental Rights, Richard A. Epstein

The Journal of Contemporary Legal Issues

The modern interest in the twin cases of Meyer v. Nebraska, and Pierce v. Society of Sisters has sparked a renewed curiosity in the intellectual foundations and current applicability of those two cases. In this instance, I stress less the constitutional underpinnings of the cases in order to focus more on their natural law approach to the parent-child relationship. Based on Lockean principles, I conclude that the standard rules of abuse and neglect offer the sole justification for such intervention, where the state is put to a high standard of proof for intervention. This framework has had only an …

Parental Rights, Parental Choice, And State Public Education Mandates, Nicole Stelle Garnett

The Journal of Contemporary Legal Issues

Pierce v. Society of Sisters and Meyer v. Nebraska were cases about parental rights in general, and parental choice in particular. Both centered on a challenge to a state’s legal effort to reduce or eliminate the educational choices available to parents—in the former, by requiring students to attend public schools, in the latter, by requiring instruction in all schools, public and private, be conducted in English. Pierce and Meyer also were about state efforts to forge a homogeneous American citizenry by limiting the educational choices available to parents. As Justice McReynolds observed in Meyer, “The desire of the Legislature …

The Centennial Of Meyer And Pierce: Parents’ Rights, Gender-Affirming Care, And Issues In Education, Ira C. Lupu

The Journal of Contemporary Legal Issues

This paper was prepared for a Symposium, held in March 2024, marking the centennial of the Supreme Court’s decisions in Meyer v. Nebraska (1923) and Pierce v. Society of Sisters (1925). At their inception, Meyer and Pierce reflected constitutional principles of economic freedom and parental control of their children’s education. Part I traces the path of ideas put in motion by Meyer and Pierce. These include the decline of their economic freedom component and the broader grounding of their doctrines of parental authority. Eventually, the chameleon-like legacy of Meyer and Pierce stretched to include First Amendment concerns of religious …

The Conservative Response To Transformative Disruption: Voice Or Exit 100 Years After Meyer And Pierce?, Neal Mccluskey

The Journal of Contemporary Legal Issues

In 1923 and 1925, respectively, the U.S. Supreme Court rulings in Meyer v. Nebraska and Pierce v. Society of Sisters established limits on the ability of government to constrain what children’s education contains and where it occurs. The Court recognized the “right” of parents to exercise basic control over those things. One hundred years later, we are seeing a renewed emphasis on “parental rights,” both with booming growth of “school choice” programs that allow government-connected funding to follow children to educational options their parents select and efforts to constrain what public schools do. The position of conservatives on such parental …

Norovirus Co-Opts Ninj1 For Selective Protein Secretion, Jaewon Song, Wandy L Beatty, Anthony Orvedahl, Et Al.

2020-Current year OA Pubs

Plasma membrane rupture by Ninjurin-1 (NINJ1) executes programmed cell death, releasing large cellular damage-associated molecular patterns (DAMPs). However, the regulation and selectivity of NINJ1-mediated DAMP release remain unexplored. Here, we uncover that murine norovirus (MNoV) strategically co-opts NINJ1 to selectively release the intracellular viral protein NS1, while NINJ1-mediated plasma membrane rupture simultaneously bulk-releases various cellular DAMPs. Host caspase-3 cleaves the precursor NS1/2, leading to NS1 secretion via an unconventional pathway. An unbiased CRISPR screen identifies NINJ1 as an essential factor for NS1 secretion. During infection, NINJ1 is recruited to the viral replication site, where it oligomerizes and forms speckled bodies, …
