The spread of SARS-CoV-2, like that many other pathogens, is governed by heterogeneity. "Superspreading," or "over-dispersion," an important factor in transmission, yet it hard to quantify. Estimates from contact tracing data are prone potential biases due the increased likelihood detecting large clusters cases, and may reflect variation behavior more than biological In contrast, average number secondary infections per routinely estimated household surveys, these studies can minimize testing...
In-line lensless digital holography has great potential in multiple applications; however, reconstructing high-quality images from a single recorded hologram is challenging due to the loss of phase information. Typical reconstruction methods are based on solving regularized inverse problem and work well under suitable image priors, but they extremely sensitive mismatches between forward model actual imaging system. This paper aims improve robustness such algorithms by introducing adaptive...
The diagnosis of urinary tract infection (UTI) currently requires precise specimen collection, handling infectious human waste, controlled urine storage, and timely transportation to modern laboratory equipment for analysis. Here we investigate holographic lens free imaging (LFI) show its promise enabling automatic analysis at the patient bedside.We introduce an LFI system capable resolving important clinical biomarkers such as red blood cells, white crystals, casts in 2 mm thick...
Abstract Purpose Healthcare facilities are obligated to implement strategies protect healthcare workers from exposure hazardous drugs, including any real or potential risk contaminated surfaces. Guidelines broad and lack sufficient detail for establish clear effectiveness targets their decontamination procedures. Our goal in this analysis was measure the of a procedure pharmacy buffer room with 5 antineoplastic drugs. Methods Six rounds contamination, decontamination, wipe sampling were...

Urinalysis is an essential diagnostic tool in evaluating health and disease of the genitourinary tract. A urinalysis typically consists dipstick testing, which can detect red blood cells, white bacteria, microscopic evaluation urine sediment after centrifugation, further reveals other biomarkers such as crystals casts. In in-patient hospital setting, ordered suspected, drawing from collection bag a foley catheter sending sample to core laboratory for analysis. To improve access biomarkers,...
Urinary tract infections (UTIs) are a common condition that can lead to serious complications including kidney injury, altered mental status, sepsis, and death. Laboratory tests such as urinalysis urine culture the mainstays of UTI diagnosis, whereby specimen is collected processed reveal its cellular chemical composition. This process requires precise collection, handling infectious human waste, controlled storage, timely transportation modern laboratory equipment for analysis. Holographic...
