Assessment of Soil Erosion Over Six Decades in a Long‐Term Experiment Using Fallout 137Cs and RUSLE: A South American Case Study

open access: yesLand Degradation &Development, EarlyView.
ABSTRACT Soil erosion remains a major global concern affecting agricultural productivity and land sustainability. This study investigates the magnitude and variability of soil erosion in a long‐term experiment (LTE) established in 1963 in Colonia, Uruguay, aiming to compare the performance of the 137Cs tracer technique and the RUSLE model across ...

Highly Versatile Real‐Time Optical Noise Filtering Through Temporal Cloaking

open access: yesLaser &Photonics Reviews, EarlyView.
Conventional bandpass filtering strategies may be insufficient for recovering optical waveforms under extremely noisy conditions. We demonstrate a temporal‐cloaking denoising strategy enabled by the temporal Talbot effect, which concentrates the coherent signal of interest into short temporal slots while broadband noise remains temporally spread.

Dynamic Profiling of Circulating Tumor Cells and MYC/PTEN Alterations in Prostate Cancer Patients Undergoing Radical Prostatectomy in Amazon Population

open access: yesMolecular Carcinogenesis, EarlyView.
ABSTRACT Prostate cancer (PCa) is the second most frequently diagnosed malignancy among men and the sixth leading cause of cancer‐related mortality worldwide. Radical prostatectomy remains the standard treatment for localized disease; however, approximately one‐third of patients develop biochemical recurrence within 10 years. Although prostate‐specific

Differentiating Nonsuicidal Self‐Injury (NSSI) From Suicide Attempts in Adolescents: A Pilot Study

open access: yesMedicine Bulletin, EarlyView.
ABSTRACT Background Differentiating between nonsuicidal self‐injury (NSSI) and suicide attempts (SA) in adolescents is crucial due to distinct underlying motivations, treatment needs, and potential outcomes associated with each behavior.

Genome‐Wide Assessment Reveals Ancestral Differences in Homozygosity Patterns Potentially Linked to Parkinson's Disease Etiology

open access: yesMovement Disorders, EarlyView.
Abstract Background Recessive genetic variation and extended runs of homozygosity (ROHs) may contribute to the unexplained heritability of Parkinson's disease (PD), particularly in diverse and understudied populations. Objective We conducted the first large‐scale, multi‐ancestral investigation of PD to examine the impact of genome‐wide homozygosity on ...
