An Examination of Ongoing Associations Between Ethnic/Racial Discrimination and Experiences of Belonging Among Black and Latinx Students Attending a Predominantly White Institution

open access: yesJournal of Community &Applied Social Psychology, Volume 36, Issue 4, July/August 2026.
ABSTRACT Using longitudinal data collected across four years of college among a sample of Black and Latinx students enrolled at a predominantly White Institution (PWI; N = 170; 71% women), the present study investigated how experiences of ethnic/racial discrimination on campus may have influenced students' sense of belonging across their college years.

Some infinite series summations involving linear recurrence relations of order 2 and 3 [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
This paper extends known results of second and third order recursive sequences through extensive formulations of properties of the roots of their characteristic equations, some are old but most are new. They are applied to novel studies of Σₙ₌ₒ^∞ aₘₙ/10ⁿ⁺

A Modern Metrical Baseline for Sexing Sheep Horn‐Cores

open access: yesInternational Journal of Osteoarchaeology, Volume 36, Issue 4, Page 925-934, July/August 2026.
ABSTRACT Sex determination is essential for reconstructing past livestock management, yet the limited skeletal sexual dimorphism of sheep hinders the identification of ewes, rams, and wethers in archaeological assemblages. Horn‐cores are the most sexually dimorphic element of the sheep skeleton, and here, we establish a new metrical baseline for ...

Silver‐Alloyed Wide‐Bandgap (Ag,Cu)(In,Ga)S2 Thin‐Film Solar Cells With 15.5% Efficiency

open access: yesProgress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 942-956, July 2026.
This study reports improvements in compositional homogeneity, microstructure, enhanced radiative recombination, and extended carrier lifetime of CIGS absorber via Ag incorporation. The optimal Ag‐alloyed CIGS solar cells achieve 15.5% PCE and 948 mV VOC, competing with the VOC of the Ag‐free reference sample from the same batch.

A Block Encryption Construction Based on Bi-Periodic Pell Matrices and Elliptic Curve Group Operations

open access: yesAxioms
This paper presents a theoretical algebraic block transformation based on bi-periodic Pell matrices and elliptic-curve point-valued blocks. The construction uses block-dependent scalar key matrices Ki=P~m+i−1(a,b)∈GL2(Fq) to transform plaintext blocks ...

Time Quasilattices in Dissipative Dynamical Systems

open access: yesSciPost Physics, 2018
We establish the existence of 'time quasilattices' as stable trajectories in dissipative dynamical systems. These tilings of the time axis, with two unit cells of different durations, can be generated as cuts through a periodic lattice spanned by two ...

The Class Gap in Career Progression: Evidence From U.S. Academia

open access: yesEconometrica, Volume 94, Issue 4, Page 1345-1373, July 2026.
Unlike gender or race, class background is rarely a focus of research on career progression, or of DEI efforts in elite occupations. Should it be? In this paper, we document a large class gap in career progression in one occupation—U.S. tenure‐track academia—using parental education to proxy for class background.

Community building through play: Development and design of a board game for review in an undergraduate anatomy course

open access: yesAnatomical Sciences Education, Volume 19, Issue 6, Page 975-984, June 2026.
Abstract Engaging students and fostering interactions can be a challenge in large enrollment, foundational‐level, undergraduate anatomy classes. Despite the active learning environment of the anatomy laboratory, students often struggle to find study partners or even speak to fellow learners in a large classroom.

On Some Relationships Among Pell, Pell-Lucas and Modified Pell Sequences

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2010
In this study, Pell, Pell-Lucas and Modified Pell numbers are investigated. Using Binet formulas for these sequences, some relations among these sequences are obtained. Also, some sum formulas are given by these properties.

Non-Fisherian generalized Fibonacci numbers [PDF]

open access: yesNotes on Number Theory and Discrete Mathematics
Using biology as inspiration, this paper explores a generalization of the Fibonacci sequence that involves gender biased sexual reproduction. The female, male, and total population numbers along with their associated recurrence relations are considered ...
