Static and streaming algorithms for random sampling over spatial range joins

Spatial range joins have many applications, including geographic information systems, location-based social networking services, neuroscience, and visualization. However, joins incur not only expensive computational costs but also too large result sets. A practical and reasonable...

Preoperative predictors of patient-reported outcomes after joint-preserving forefoot surgery for rheumatoid arthritis

Aims: Forefoot deformities are common in patients with rheumatoid arthritis (RA) and often impair quality of life. Patient-reported outcome measures (PROMs), including the Self-Administered Foot Evaluation Questionnaire (SAFE-Q), are increasingly used to assess surgical outcomes;...

Standardization of shotgun metagenomics parameters for pks-positive enterobacteria detection in human fecal samples: Receiver operating characteristic analysis using polymerase chain reaction as reference standard

Enterobacteria harboring the polyketide synthase ( pks ) island ( clbA – clbS ), which encodes colibactin ( pks⁺ enterobacteria), is a putative risk factor for colorectal cancer. Polymerase chain reaction (PCR) is the current standard for detection. Primer-independent shotgun met...

[ 18 F ] PSMA ‐1007 PET –Based Recurrence Site Distribution and Predictors of Metastatic Disease in Patients With Biochemical Recurrence of Prostate Cancer

ABSTRACT Objectives Prostate‐specific membrane antigen positron emission tomography (PSMA‐PET) is a sensitive imaging modality for detecting recurrent prostate cancer following definitive local therapy. However, evidence on 18 F‐labeled PSMA tracers in Japanese patients with bioc...

Humidity‐Guided In Situ Polymerization for Controlled Formation of Smooth, Oriented Covalent Organic Framework Films

Efficient, reliable preparation of high-quality films of covalent organic frameworks (COFs) is essential for fully exploring the potential of this class of porous crystalline compounds in, for example, sensing and catalysis. To this end, in situ polymerization on substrates offer...
