Spectral Central Radicals and Filtered Deformations of Hochschild Cohomolog

Let \(k\) be a field and let \(A\) be a finite-dimensional unital \(k\)-algebra equipped with a finite decreasing multiplicative filtration \(F\). For \(G=\operatorname{gr}_F A\), we construct the filtration-degree spectral sequence of the normalized Hochschild cochain complex an...

Validated but unconstrained: why total-clearance data cannot constrain minor elimination pathways, and how a thirtyfold parameter revision went undetected in ocular pharmacokinetics

Mechanistic models in drug development are validated against quantities that can be measured and then used to predict quantities that cannot. This work shows that the inference from one to the other is quantifiable, and often close to empty. When the validation target is a total...

Lecturers’ and Students’ Views on The Impact of Student Support Services on Student Retention and Throughput Rates

Recent studies have demonstrated a decline in numbers of students graduating within the allotted time at various institutions of higher learning. Despite several current discussions in the Technical and Vocation Education and Training (TVET) sector to unpack the role of colleges...

Multi-Source Theory 3.0: Informational Projections, Gaussian Correlation Bounds, and Cosmological Tests

Multi-Source Theory (MST) investigates whether observable physical states can be described as projections of correlated underlying informational domains. This revision replaces broad emergence claims with a hierarchy of explicit assumptions, conditional mathematical results and a...

One-Octonion Brane-Bulk Framework — Paper CCCLXII: The Yang–Mills Mass Gap as Finite Incidence Geometry — the Shortest Colour-Singlet Loop Floor and its Hubble-Scale Dilational Complement

Mechanism paper for the gauge-sector mass gap of the One-Octonion Brane-Bulk (OOB) framework, isolated as a standalone finite-incidence statement with its scale identification and strict sector bookkeeping. Within OOB the physical question, why the gauge sector has a smallest str...

The Merge Families of Greedy Mersenne Decomposition Occur at the Base-4 Digits of 1/π

Greedy Mersenne decomposition prices every position of an admitted window in closed form: its cost table is the bit length of a linear function of 2^m modulo 2^p - 1, with the straggler positions read off Pascal's triangle. This note prices the one phenomenon that closure leaves...

Oncoplastic Reconstruction of the Anterior Chest Wall Using a Latissimus Dorsi Myocutaneous Flap: A Case Report

Background: Dermatofibrosarcoma protuberans (DFSP) is an uncommon cutaneous fibroblastic neoplasm characterized by infiltrative growth, low metastatic potential, and a high risk of local recurrence following incomplete excision. Large or recurrent tumors of the anterior chest wal...

Physical Interpretation of the Origin of the Fixed‑Value Speed of Light

In the framework of modern physics, the speed of light (approximately 300 000 km/s) serves as a fundamental physical constant widely adopted in core theories including relativity and quantum mechanics. For a long time, academic research has focused on its measurement and applicat...

Words of Authority: Evaluating the Impact of Law Enforcement Messaging on a Hacker Forum

Law-enforcement agencies increasingly target individuals considered at risk of cybercrime, yet evidence of these interventions’ effectiveness remains limited. This study evaluated an intervention in which law enforcement publicly replied to hacker-forum users with warnings about...

Enhancing Time Series Forecasting: Applying Cross-Validation Methods to Hybrid Models for Predicting GCC Stock Market Indices

Forecasting Gulf Cooperation Council (GCC) country stock market returns is challenging because these markets exhibit volatility clustering, heavy tails, oil-price sensitivity, and asymmetric responses to shocks. This study evaluates whether ARIMA–GARCH-family hybrid models improv...

Chronic Pain Uncouples Functional Brain Network Segregation From Cognitive Performance in Aging

Introduction Chronic pain (CP) disproportionately affects older adults, not only because it is more prevalent in later life, but also because it may exacerbate cognitive aging and is associated with increased dementia risk [1]. Recent research has implicated accelerated brain agi...

Fasciocutaneous Flap Reconstruction of the Inguinal Region: A Contemporary Review of Anatomy, Indications and Technique

Reconstruction of the inguinal region remains one of the most demanding problems in reconstructive plastic surgery. Defects in this area arise after vascular reconstruction, oncological lymphadenectomy, necrotizing soft-tissue infection, burns, radiotherapy and trauma, and they f...

Spontaneous Triplet Bicorial, Triamniotic Pregnancy Complicated by A Hybrid Spectrum of Selective Fetal Growth Restriction and Twin to Twin Transfusion Syndrome

BACKGROUND: Spontaneous triplet pregnancy is a rare occurrence (1 in 8,000 pregnancies) that carries an 8.2-fold higher risk of developing monochorionic placentation compared to pregnancies resulting from assisted reproductive technologies. In this case, the coexistence of the “h...

Re-Epithelialization of Donor Sites and Meshed Skin Grafts Using Cryopreserved Cultured Cutaneous Allograft (Epifast®): Experience in Patients with Extensive Burns

Extensive full-thickness burns remain a major challenge in reconstructive surgery because limited donor-site availability frequently delays definitive wound coverage and increases the risk of infection, prolonged hospitalization, and hypertrophic scarring. Cryopreserved cultured...

From Health Economic Models to Decision Support Software: A MedSID/PINCER Researcher RSE Collaboration

The MedSID/PINCER project is developing decision support software to help understand the benefits, harms and costs of prescribing safety interventions. Building on existing health economic models, the project translated Excel based modelling work into reusable research software a...

Quasi-Elastic Spectator Recoils from Atmospheric Neutrinos and the LUX-ZEPLIN 248 keV Event

The LUX-ZEPLIN (LZ) collaboration has reported a single event consistent with a xenon nuclear recoil of 248 ± 23 (stat) ± 23 (sys) keV in a 2.84 tonne-year exposure, in tension with its background-only model at 2.6σ global significance. The published background model treats atmos...

Following Scrum with part-time teams: Experiences of delivering high-quality Git and GitHub documentation for Met Office employees, partners and collaborators

The Met Office has relied on Subversion and Trac for research software version control and issue and experiment management for over 20 years. In June 2023, the Science Git Migration Project was launched to support the widespread and business-critical transition to Git and GitHub....

One-Octonion Brane-Bulk Framework — Paper CCCLX: Schwinger-n=1 as the First e7 Boundary Channel — the B^(1/2) Amplitude Law and its B^(-1/2) Aperture Complement

Derivation paper for the One-Octonion Brane-Bulk (OOB) framework's first strong-field boundary channel. With one identification, one activated e7 boundary site per magnetic flux cell, rho_e7 = B/Phi_0 = 1/(2 pi l_B^2), and two stated working assumptions, the first-channel convers...

Symbiotically Mediated Heterochrony in Primate and Human Evolution

Human evolution exhibits an unusually prolonged and integrated developmental trajectory. Delayed maturation, extended juvenile dependency, slow life history, encephalisation, craniofacial reduction and altered bodily proportions are commonly interpreted within a heterochronic fra...

The Talbird Oak: Revolutionary Violence on Hilton Head and Daufuskie

This article investigates the legend of the Talbird Oak on Hilton Head Island, South Carolina, by testing the modern historical marker’s claims against primary sources. It begins with Rev. Henry Talbird’s 1888 family history and reconstructs the Revolutionary events on Hilton Hea...
