Fusion-in-T5: Unifying Document Ranking Signals for Improved Information Retrieval
Common document ranking pipelines in search systems are cascade systems that
involve multiple ranking layers to integrate different information
step-by-step. In this paper, we propose a novel re-ranker Fusion-in-T5 (FiT5),
which integrates text matching information, ranking features, and global
document information into one single unified model via templated-based input
and global attention. Experiments on passage ranking benchmarks MS MARCO and
TREC DL show that FiT5, as one single model, significantly improves ranking
performance over complex cascade pipelines. Analysis finds that through
attention fusion, FiT5 jointly utilizes various forms of ranking information
via gradually attending to related documents and ranking features, and improves
the detection of subtle nuances. Our code is open-sourced at

A New Direct Process to Prepare YBa2Cu3O7- films on Biaxially Textured Ag{110}<211>
YBCO films were successfully prepared on biaxially textured Ag{110}
substrates by using pulsed laser deposition. X-ray diffraction results showed
that the degree of preferential orientation of Ag{110} substrates varied
with increasing annealing temperature. With a thin template layer deposited at
low temperature, YBCO film with c-axis orientation and in-plane biaxial
alignment could be obtained at high deposition temperature. Scanning electron
microscopy observation revealed that YBCO grains enlarged but Ag grains on the
surface of the YBCO films became smaller with increasing deposition
temperature. At optimal deposition conditions, Ag atoms diffuse into the YBCO
grain boundaries, and then fill in the weak-link regions in the YBCO film,
resulting in the conduction easier. Jc value of 5105A/cm2 was obtained
at 77K and zero magnetic field for the best YBCO film in our work.Comment: 9 pages, 4 figure
Canonical correlation analysis on the association between pulmonary function and obesity in early-onset COPD: CT-based body composition analysis
BackgroundWhile body composition impacts pulmonary function, the differential effects of visceral (VAT) vs. subcutaneous adipose tissue (SAT) in early-onset COPD remain unquantified.ObjectiveTo elucidate the relationship between obesity patterns and pulmonary function in early-onset COPD versus non-COPD populations, focusing on body mass index (BMI), visceral adipose tissue (VAT), and subcutaneous adipose tissue (SAT) distribution.MethodsThis retrospective cohort study analyzed 290 patients (144 early-onset COPD, 146 non-COPD) aged 20–50 years. Body composition (BMI, SAT, VAT) was quantified via CT at the L1 vertebral level. Pulmonary function was assessed by bronchodilator responsiveness testing (FEV₁/FVC, MEF₇₅, MEF₅₀, MEF₂₅). Canonical correlation analysis (CCA) was used to evaluate the multidimensional associations between body composition and pulmonary function.ResultsCanonical correlation analysis revealed distinct multidimensional relationships between body composition and pulmonary function across study cohorts (p < 0.05). In the early-onset COPD cohort (N = 144), a statistically significant canonical variate (r = 0.383, λ = 0.172) demonstrated moderate association strength linking body composition (X1: BMI, SAT, VAT) with pulmonary function (Y1: FEV1, FVC, MEF75, MEF25). Conversely, the non-COPD group (N = 146) exhibited stronger canonical correlation (r = 0.537, λ = 0.405), with body composition (X2: BMI, VAT) associating with pulmonary function (Y2: FEV1, FVC).ConclusionIn summary, early-onset COPD patients with elevated BMI and VAT but reduced SAT exhibited improved pulmonary function across most parameters. This enhancement was not observed in MEF50 and MEF25. In contrast, the non-COPD cohort exhibits overall respiratory enhancement, as the cross-loading coefficient of MEF25—an indicator reflecting the weight of a variable in contributing to the canonical variate—is extremely small (0.05) and has a negligible impact on the overall association
Integrating Ki-67 and Treatment Strategies to Guide Prognosis in High-Grade Meningiomas: A Multivariable Analysis of Prognostic Factors in WHO Grade II/III Meningiomas
Introduction High-grade meningiomas (WHO Grade II/III) are associated with high recurrence rates and poor survival despite aggressive therapy Adjuvant radiotherapy’s (RT) benefit after gross total resection (GTR) remains uncertain and histopathologic markers such as Ki-67 may further refine risk stratification and inform postoperative management AIM: to identify the role of RT and clinicopathologic predictors of local failure-free survival (LFFS) and overall survival (OS) in high-grade meningiomashttps://jdc.jefferson.edu/radoncposters/1004/thumbnail.jp
