Gamma-ray spectra of IAEA and proficiency-test reference materials measured in one laboratory between 2013 and 2022, with reference activity concentrations decay-corrected to the acquisition date of each spectrum. The archive contains 255 spectra: 176 measured with an ORTEC GMX35P4-70 n-type coaxial HPGe detector and 79 with two Canberra HPGe detectors. All spectra are rebinned to a common 0.5 keV grid from 20 to 2900 keV after refitting the energy calibration. Labels cover the 226Ra series, 228Ra, 40K, 137Cs and other certified nuclides, with standard uncertainties. Metadata give material, detector, geometry, sample mass, fill height, acquisition time, live time and a measurement-group identifier that links partial saves of one acquisition. Background spectra and the test-set definition used in the accompanying article are included.

This study investigated the moderating role of task identity between organisational commitment and work engagement among employees in Beverage Company in Ogun State, Nigeria. The study adopted a cross sectional survey design. Three standardised instruments - Utrecht Work Engagement Scale (UWES), Organisation Commitment Scale (OCS) and Job Diagnostic Survey (JDS) – were used for data collection. Simple random sampling technique was used to select 293 employees of a beverage company in Ogun State, Nigeria. The mean responses were 75.98, with a standard deviation of 15.32 (M = 75.98, SD = 15.32) Two research hypotheses were tested to guide the study. Data collection was physically done at the organisation. The mean and standard deviation were established through descriptive statistics while hierarchical multiple regression was used to test the moderating role of task identity in the relationship between organisational commitment and work engagement. Statistical significance was evaluated at the .05 level. The results showed that organisational commitment was positively correlated with work engagement (r = .461; p< .01) and task identity (r = .510; p<.01). Also work engagement was positively related to task identity (r = .686; p< .01). Task identity significantly moderated the relationship between organisational commitment and work engagement, such that the relationship becomes stronger when task identity is high. Based on these findings, it is recommended that organizations should redesign jobs to encompass task identity by allocating complete, meaningful tasks that reflect employees’ contributions. Management should also provide enabling environment thorugh trust, fairness, participation, recognition and effective communication to strengthen organization commitment and increase work engagement

Wernicke-Korsakoff syndrome (WKS) is a neurological disorder resulting from severe thiamine deficiency and is classically associated with chronic alcohol use. Non-alcoholic causes, though less well recognised, include prolonged vomiting, restrictive dietary intake, and other malnourished states. We report a 25-year-old woman with no history of alcohol consumption who presented with a two-day history of confusion, unsteadiness, and horizontal diplopia, together with an inability to recognise close family members, following three weeks of poor oral intake and recurrent vomiting associated with a restrictive diet. Examination revealed disorientation, confabulation, profound anterograde amnesia, horizontal nystagmus, and a broad-based gait. Magnetic resonance imaging demonstrated changes consistent with Wernicke encephalopathy, and serum thiamine was low. She was treated with high-dose intravenous thiamine prior to glucose administration, along with supportive care. Nystagmus and gait ataxia improved, but the amnestic deficit and confabulation persisted at discharge. This case underscores that thiamine depletion from restrictive eating and prolonged vomiting alone, independent of alcohol use, can precipitate the full Wernicke-Korsakoff triad in young women, and highlights the need for a high index of suspicion and prompt thiamine replacement to prevent irreversible neurological sequelae.

This article compares two frameworks for diagnosing chaos. Karve, Rose, Campbell, and Polkovnikov introduce the speed-Fisher information, a response-theoretic susceptibility measuring irreversible entropy or energy production when a stationary state is subjected to a slow cyclic drive. Its behavior is governed by the low-frequency weight of a score-weighted spectral function. If that weight remains nonzero at zero frequency, the diagnostic diverges in the quasistatic limit, signaling breakdown of adiabatic following; if it decays rapidly, the response stays bounded. Independently, The Architecture of Chaos distinguishes thin chaos, where local instability remains confined and a projected reachable set avoids an operational failure set, from thick chaos, where instability becomes transport-effective and reaches failure. The Trojan Universality Class provides protected thin chaos through spectral gaps, normal-form suppression, and long-time confinement. The article argues that the frameworks are complementary rather than equivalent. Under explicit assumptions connecting the driven observable to the projected failure coordinate, rapid spectral decay corresponds to preserved thinness and bounded response, while a low-frequency plateau forces consumption of a finite failure margin and produces thick chaos. The beta-Fermi-Pasta-Ulam-Tsingou chain illustrates this: weak nonlinearity gives metastable thin behavior and bounded response; strong nonlinearity produces resonance overlap, low-frequency spectral weight, divergent response, and thermalization. The conclusion is that response theory supplies a measurable proxy for erosion of thinness margins, while architectural analysis explains why protection holds or fails and what it means operationally. Together they yield a sharper, hybrid classification of nonlinear dynamics.

Актуальность. Врождённые пороки сердца (ВПС) — самая распространённая группа врождённых аномалий развития и одна из ведущих причин неонатальной смертности [1–4]. Часть критических ВПС (CCHD) остаётся клинически нераспознанной к моменту выписки из родильного дома, что повышает риск декомпенсации и летального исхода. Цель — обобщить современные данные о подходах к диагностике ВПС у новорождённых и значении пульсоксиметрического скрининга. Методы. Проведён описательный (narrative) обзор публикаций PubMed/MEDLINE, Scopus, Web of Science, Google Scholar за 2009–2025 гг. с включением фундаментальных более ранних работ и доступных материалов Узбекистана. Результаты. Международный опыт (рекомендации AAP, AHA, CDC, европейский консенсус) подтверждает высокую специфичность пульсоксиметрии при умеренной дополнительной чувствительности к клиническому осмотру. Практическое значение. Стандартизированный протокол пульсоксиметрии в сочетании с осмотром и эхокардиографией обеспечивает своевременное направление к кардиологу. Заключение. Повсеместное внедрение неонатального пульсоксиметрического скрининга обоснованно снижает риск поздней диагностики критических ВПС.
