Photonic compressive sensing of microwave signals with enhanced compression ratio and frequency range via optical pulse random mixing.

We propose and demonstrate a photonic compressive sensing (PCS) scheme for microwave signals using optical pulse random mixing, significantly enhancing both the compression ratio and operating frequency range. Unlike continuous-wave laser-based PCS systems, our approach mitigates the non-ideal characteristics of the pseudo-random binary sequence (PRBS), such as sloped edges and amplitude jitters, resulting in a more ideal compression process. Additionally, the high harmonic components of the optical pulses further facilitate wideband downconversion, improving the system's operating frequency range.

First Report of Causing Pear Anthracnose in China.

China is a major producer of pears in the world and anthracnose is the most important disease, which may include fruit rot and early defoliation, and further brings enormous economic losses. In August of 2023, a sudden outbreak of anthracnose disease, ranging from 70% to 90% disease incidence, occurred on fruits of Pyrus pyrifolia (Burm.f.

Pretheranostic agents with extraordinaryNIRF/photoacoustic imaging performanceand photothermal oncotherapy efficacy.

Cervical cancer, the most common gynecological malignancy, significantly and adversely affects women's physical health and well-being. Traditional surgical interventions and chemotherapy, while potentially effective, often entail serious side effects that have led to an urgent need for novel therapeutic methods. Photothermal therapy (PTT) has emerged as a promising approach due to its ability to minimize damage to healthy tissue.

Ultrasensitive photoelectrochemical detection of cancer markers based on heterojunctions constructed from BiO star-like flower nanoclusters and CdS hollow nanorods.

CYFRA21-1 is a tumor marker for lung cancer, and its rapid and accurate detection can provide evidence for the early diagnosis of lung cancer. In this work, Bi-Fe turnbull blue analogues (Bi-Fe-TBA) were synthesized by the self-templating method. BiO-SFNs was prepared by simple oxidation in air using Bi-Fe-TBA as a template.

Personalized theta-burst stimulation enhances social skills in young minimally verbal children with autism: a double-blind randomized controlled trial.

Background: Minimally verbal children with autism are understudied and lack effective treatment options. Personalized continuous theta-burst stimulation (cTBS) targeting the amygdala and its circuitry may be a potential therapeutic approach for this population.

Methods: In a double-blind randomized controlled trial, minimally verbal children with autism (ages 2-8 years) received 4 weeks of cTBS.
