Rate of approximation of blending type modified univariate and bivariate λ-Schurer-Kantorovich operators

Kuwait Journal of Science
In this work, we investigate some approximation properties of blending type univariate and bivariate Schurer-Kantorovich operators based on shape parameter λ ∈ [−1, 1]. We evaluate some moment estimates and obtain several direct theorems.

Bivariate tensor product ( p , q ) $(p, q)$ -analogue of Kantorovich-type Bernstein-Stancu-Schurer operators

Journal of Inequalities and Applications, 2017
In this paper, we construct a bivariate tensor product generalization of Kantorovich-type Bernstein-Stancu-Schurer operators based on the concept of ( p , q ) $(p, q)$ -integers.

Giving and receiving help in three contexts as predictors of alcohol outcomes in a longitudinal study of sober living house residents

American Journal of Community Psychology, EarlyView.
Abstract Although peer support is central to the social model approach emphasized in sober living houses (SLHs), no longitudinal studies have examined helping among SLH residents. This longitudinal study examined benefits of helping in three contexts among SLH residents. Data were from 205 participants entering 28 SLHs across 2021–2023. Interviews were

A Dunkl type generalization of Szász operators via post-quantum calculus

Journal of Inequalities and Applications, 2018
The object of this paper to construct Dunkl type Szász operators via post-quantum calculus. We obtain some approximation results for these new operators and compute convergence of the operators by using the modulus of continuity.

Examining pathways by which socioeconomic instability in adolescence influence sexual health during emerging adulthood in an agricultural setting in California

American Journal of Community Psychology, EarlyView.
Abstract This study investigates the longitudinal impact of socioeconomic instability on teen pregnancy and sexually transmitted infection (STI) diagnosis among adolescents and young adults (AYA) living in an agricultural region and examines pathways including supportive family and social structures, decision making autonomy in romantic relationships ...

Some inequalities and numerical results estimating error of approximation for tensor product kind bivariate quantum beta-type operators and pertaining to GBS variant

Journal of Inequalities and Applications, 2022
In this study, we investigate some inequalities estimating the error of approximation for new defined tensor product kind quantum beta-type operators on rectangular regions, and we give an inequality in weighted mean.

Hierarchy of general invariants for bivariate LPDOs

, 2005
We study invariants under gauge transformations of linear partial differential operators on two variables. Using results of BK-factorization, we construct hierarchy of general invariants for operators of an arbitrary order.

Work Disability, Early Retirement, and Loss of a Loved One in the World Trade Center Health Registry Cohort

American Journal of Industrial Medicine, EarlyView.
ABSTRACT Background Existing research on the economic outcomes of 9/11 remains limited and has primarily focused on early retirement. Little is known about the prevalence of work disability and loss of a loved one and whether they are associated with survey attrition.

The morphology of the oval window in Paranthropus robustus compared to humans and other modern primates

The Anatomical Record, EarlyView.
Abstract The oval window (OW) is an opening connecting the inner and middle ear. Its area has been shown to consistently scale with body mass (BM) in primates, and has been used alongside semi‐circular canal (SCC) size to differentiate Homo sapiens and fossil hominins, including Paranthropus robustus.

Patterns of spinal motion, kinematic spaces and the land‐to‐sea transition in carnivorans

The Anatomical Record, EarlyView.
Using 3D reconstructions, we quantify intervertebral joint mobility to investigate how cervical, thoracic, and lumbar vertebral regions evolved distinct kinematic roles in pinnipeds. The findings reveal lineage‐specific adaptations for swimming and highlight the functional significance of vertebral joint flexibility in ecological transitions.
