Abstract:Manual grading of boards limits throughput and introduces operator variability. We deploy line-scan cameras on a production conveyor and train a multi-head detector for knots, splits, and stain using operator-annotated imagery from three species mixes. Real-time inference achieves agreement with expert graders above ninety-two percent on hold-out shifts while flagging edge cases for human review, reducing downgrade revenue loss in pilot runs.
Abstract:Prolonged displacement exposes adolescents to cumulative adversity that standard talk therapies may not address. We adapt a brief narrative exposure protocol for group delivery in community centres and randomize 186 participants aged fourteen to seventeen. Intent-to-treat analysis at three-month follow-up shows greater PTSD symptom reduction than a psychoeducation control, with gains maintained on six-month caregiver reports and no increase in session dropout.
Abstract:Lightweight magnesium structures corrode rapidly in chloride-rich environments unless surface barriers limit galvanic coupling. We optimize silicate–phosphate electrolyte compositions and pulse regimes to grow dense ceramic layers on AZ31 sheet. Potentiodynamic polarization and salt-spray exposure demonstrate order-of-magnitude current-density reduction versus bare substrate, with cross-section microscopy linking performance to pore sealing and crystalline phase distribution.
Abstract:National immunization coverage masks district-level pockets of refusal driven by trust and access barriers. We link geocoded household surveys with census covariates in a multilevel logistic framework with spatial random effects. Posterior maps identify municipalities where hesitancy exceeds national averages after adjusting for education and urbanicity, enabling targeted community engagement without over-interpreting sparse direct estimates.
Abstract:Structural thinning precedes measurable visual-field loss, yet single time-point scans misclassify fast progressors. We derive a composite index from circumpapillary nerve-fibre thickness, ganglion-cell complex volume, and scan-quality metrics in a five-year observational registry. Cox models show the index stratifies conversion risk independently of intraocular pressure, supporting enriched enrolment for neuroprotective trials.
Abstract:Official transit inventories often omit shared taxis and motorcycle routes that serve peripheral districts. We combine smartphone traces from volunteer drivers with focus-group sketch maps to build a multimodal graph for a city of 420,000 inhabitants. Overlay analysis reveals transfer hubs absent from municipal plans and quantifies access-time gains from hypothetical feeder formalization scenarios discussed with neighbourhood councils.
Abstract:Integrating nitrogen-fixing legumes into cereal-dominated rotations may rebuild depleted organic matter without heavy fertilizer inputs. After eighteen years of factorial management, particulate and mineral-associated carbon pools respond differently to faba bean inclusion and reduced tillage. Structural equation modelling links macroaggregate protection to slower decomposition of labile fractions, informing extension advice on minimum disturbance paired with pulse crops.
Abstract:Delayed recognition of sepsis increases mortality in critical care units. We train a lightweight transformer on multivariate vital-sign streams sampled at five-minute intervals from a retrospective cohort of 6,800 admissions. The model flags deterioration six hours before clinician-documented suspicion with higher sensitivity at fixed false-alarm rates than gradient-boosted baselines, suggesting utility as a triage overlay rather than autonomous therapy.
Abstract:This study evaluated the effects of mannanoligosaccharides (MOS) on gut health, immune response, and productivity in ducks in the context of reducing antibiotic use in poultry production. In vitro experiments demonstrated that MOS (0.1–0.4%) effectively adsorbed pathogenic bacteria, including E. coli O2, P. vulgaris, K. pneumoniae, and C. diversus, indicating their strong anti-adhesive potential against enteropathogens. In vivo, 250 one-day-old ducks were randomly allocated into five groups and fed diets supplemented with MOS at inclusion levels of 0.1–0.4% over a 49-day rearing period. The highest inclusion level (0.4%) significantly improved intestinal microbiota balance by reducing E. coli counts while increasing populations of Lactobacillus spp. and Bifidobacterium spp. (p<0.05), without affecting intestinal pH. Mannanoligosaccharide supplementation significantly enhanced innate immune responses as evidenced by increases in serum bactericidal activity 34.85%, lysozyme activity 33.82%, and phagocytic activity 32.81%. Improvements in growth performance were observed, with a 14.3% increase in final body weight and a 2.5% reduction in feed conversion ratio compared with the control group. These findings demonstrate that MOS act as effective prebiotic feed additives that improve intestinal microbiota composition, strengthen immune function, and enhance productivity in ducks, supporting their potential use as an alternative to antibiotic growth promoters in modern poultry production systems.
Abstract:Lightweight lattice heat exchangers must survive cyclic thermal gradients during startup–shutdown. Selective laser melting produces struts with surface roughness and microstructural gradients that alter crack initiation sites. Isothermal and out-of-phase thermomechanical tests on dogbone specimens extracted from unit cells reveal shorter lives than bulk wrought material at matched stress amplitudes, motivating post-process hot isostatic pressing to close internal porosity.
