Comparison Of Umbral Dot Physical Properties In Developed And Undeveloped Sunspots, Muhammed Ali̇ Çalişir, Ali̇ Kilçik, Vasyl Yurchyshyn

Turkish Journal of Physics

Sunspots are cool regions where the magnetic field is significantly stronger than in the surrounding photosphere, and their darkest central regions are known as the umbra. Umbral dots (UDs) are small, bright features within the umbra that represent convective motions partially suppressed by strong magnetic fields. In this study, high-resolution images from the Goode Solar Telescope (GST) at Big Bear Solar Observatory (BBSO) were used to analyze four sunspots at different evolutionary stages, including two developed and two undeveloped sunspots. The physical properties of UDs, including brightness, diameter, eccentricity, lifetime, and dynamic velocity, were measured and compared across these sunspots …

Stress–Strain Behavior Of The High-Entropy Cantor Alloy Crmnfeconi Using A Deep Neural Network Potential, Nguyen Le Hoai Phuong, Le Huu Nghia, Huynh Khanh Van, Vo Khuong Dien, Nguyen Thanh Tien

Turkish Journal of Physics

Machine learning interatomic potentials (MLIPs) provide an efficient approach to large-scale molecular dynamics simulations of high-entropy alloys. In this work, an MLIP trained on AIMD data was developed for the CrMnFeCoNi Cantor alloy and validated against DFT calculations. In addition, we compared MLIP results with those obtained using the classical modified embedded atom method (MEAM)-based interatomic potential for the CrMnFeCoNi Cantor alloy. The model achieved energy and force RMSEs of 7.39 x 10-6 meV/atom and 4.46 x 10-3 eV/A, respectively. Tensile simulations demonstrated that the MLIP accurately reproduced the stress–strain response, elastic constants, and deformation mechanisms observed in DFT calculations. …

Spacer-Mediated Gold Nanocube Arrays For Edge-Localized Excitonic Enhancement In Monolayer Mos2​, Abdullah Efe Yildiz, Emre Ozan Polat

Turkish Journal of Physics

Plasmonic nanostructures offer an effective route for enhancing light-matter interaction in atomically thin semiconductors, whose optical response is intrinsically limited by their subnanometer active thickness. Here, we numerically investigate excitonic enhancement in monolayer (ML) Molybdenum Disulfide (MoS2) coupled to size-tuned gold (Au) nanocube arrays separated by thin aluminum oxide (Al2O3) and hexagonal boron nitride (h-BN) spacer layers. By varying the nanocube side length, the localized surface plasmon resonance is tuned across the visible spectral range to modulate the A- and B-excitonic transitions of monolayer MoS2.We show that the nanocube-size-dependent spectral redshift can be further controlled through the spacer material and …

Theoretical Construction Of Light Hexaquarks And Their Substantiation By Seven-Dimensional Representation Of Su(2) Group, Mayank Joshi, Shuchi Bisht, Navjot Hothi, Manish Bisht

Turkish Journal of Physics

This manuscript presents a theoretical approach to constructing light hexaquarks using up and down quarks. These light exotic hexaquarks are shown to exhibit a seven-dimensional representation of the SU(2) isospin group. Additionally, the isospin septuplet is developed along with the quintet, triplet, and singlet representations for these light exotic hexaquarks. These particles are essentially mesonic in nature and also satisfy the requirements of the Kronecker product. Furthermore, the physical characteristics and weights of the respective states are intrinsically provided for these light hexaquarks.

Strengthening Communities With Extension's People Empowering People Program, Stacey F. Stearns, Faye Griffiths-Smith

Journal of Extension

Programs that encourage personal growth, community connections, and civic engagement are even more essential as digital technology and virtual platforms disconnect residents from communities. The University of Connecticut People Empowering People (UConn PEP) program is one option. It strengthens individuals and communities through a 10-week facilitated program, hosted by the community, and taught by UConn-trained facilitators. UConn PEP has expanded to other states, was translated to Spanish, Arabic, and Portuguese, and three other countries expressed interest in offering the PEP curriculum. Programs such as this are an area for continuous expansion as Extension adapts to the changing needs of audiences.

Trials registered at least two years before the search date (January 2026) were included. Trial characteristics, including funding source, intervention type, enrollment size, blinding, number of centers, and recruitment location, were extracted. Publication …

Advancing Tuberculosis Vaccination: Immunological Insights And Emerging Strategies For Improved Protection, Zhicheng Zhang, Crystal Sanchez, Derek Baker, Jeries Bawardi, Victoria Renteria, Sheralyn Sanchez, Subramanian Dhandayuthapani, Jessica Chacon

School of Medicine Publications

Tuberculosis (TB) remains one of the leading causes of infectious disease mortality worldwide despite widespread Bacille Calmette-Guérin (BCG) vaccination and decades of control efforts. The limited and variable efficacy of current vaccination strategies, particularly against adult pulmonary disease, highlights the need for a deeper understanding of the host immune mechanisms that determine protection against Mycobacterium tuberculosis. While traditional approaches to TB vaccine development have largely focused on pathogen-specific immunity and clinical efficacy, emerging evidence suggests that successful TB control may depend equally on the strategic modulation of host immune responses. This narrative review examines the immunological basis of TB vaccination, …

Its variable presentation can overlap with more common causes of liver disease and delay recognition. We present a 28-year-old patient with one week of worsening jaundice, right upper quadrant abdominal pain, nausea and vomiting, and marked hyperbilirubinemia. Given a history of heavy alcohol use and a Maddrey Discriminant Function score of 73, severe alcohol-associated hepatitis was initially suspected. However, several months of reported alcohol abstinence, a strong maternal family history of early-onset cirrhosis, imaging evidence of …

Design Implications For Teacher-Configurable Generative Ai Writing Tools: A Participatory Design Study With Storybot, Ariel Han, Shenshen Han, Zhenyao Cai, Joey Huang, Franceli Cibrian, Kylie Peppler

Engineering Faculty Articles and Research

As generative AI (GenAI) tools become accessible, their integration into K–12 writing presents opportunities and challenges. This study partnered with 21 primary school teachers in a participatory co-design process to develop StoryBot, a teacher-configurable GenAI story-authoring platform. Teachers identified instructional needs and learning outcomes that informed system features, including genre-specific writing scaffolds, configurable prompts, and constraints on full-text generation to preserve student voice. The platform positions educators as co-designers of AI behavior rather than passive users. We conducted a pilot writing workshop with 13 youth (ages 8–12) and a focus group with six educators to examine how the platform influenced …

Navigating Systemic Neglect: Educator Perspectives On Supporting Central American Unaccompanied Minors In California Public Schools, Stephany Cuevas, Martha C. Franco

Education Faculty Articles and Research

This qualitative study examines how educators in California public schools conceptualize and respond to the needs of Central American unaccompanied minors. Using a sociohistorical trauma-reducing framework, we analyze interviews with 29 teachers, counselors, social workers, and afterschool providers. Findings highlight structural barriers to resources and identification, academic and linguistic challenges shaped by interrupted schooling, unmet mental health and socioemotional needs, and the burden educators assume as advocates within trauma-producing systems. Despite employing relational, justice-oriented practices, educators work within conditions that undermine sustainability, underscoring the need for trauma-reducing, equity-driven reforms.

Faculty Journal Articles

Surgical removal of tumor-draining lymph nodes (tdLNs) is commonly performed in cancer patients. Here, we investigated whether immune checkpoint blockade (ICB) responses persist after resection of tdLNs, important sites for the initiation and maintenance of anti-cancer immunity. Melanoma patients remained responsive to programmed death 1 (PD-1) blockade after regional LN dissection. Similarly, ICB efficacy persisted after tdLN resection in orthotopic murine melanoma and mammary carcinoma models. Following tdLN removal, interstitial fluid containing soluble antigen was diverted through interstitial spaces across lymphosome boundaries to distant LNs, wherein cancer-derived antigen was acquired and presented to T cells by LN-resident type I conventional …

Representation Of Beauty: Gendered Discourses In Czech And Indonesian Advertisements, Indah Kurnia Herliani, Nurenzia Yannuar, Yusnita Febrianti, Ahmad Faizuddin

Bahasa dan Seni: Jurnal Bahasa, Sastra, Seni, dan Pengajarannya

Beauty advertising is a public multimodal site in which gendered beauty ideals are made visible and linked to consumption. This study examines how beauty is constructed in the linguistic landscape (LL) of public advertisements in two localized urban settings: Olomouc, the Czech Republic, and Malang, Indonesia. We combine LL as the spatial and sociolinguistic framework, multimodal analysis through Cheong's (2004) Generic Structure Potential (GSP), and Feminist Critical Discourse Analysis (FCDA), operationalized through Fairclough's (1992) three-dimensional model. Rather than treating the two sites as representative of their countries or regions, we use them as comparative case studies to examine how similar …
