Inclined Obstacle Recognition and Ranging Method in Farmland Based on Improved YOLOv8

World Electric Vehicle Journal
Unmanned tractors under ploughing conditions suffer from body tilting, violent shaking and limited hardware resources, which can reduce the detection accuracy of unmanned tractors for field obstacles.

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Stopovers of Swans (Cygnus cygnus and C. bewickii) (Anatidae, Aves) in the Agricultural Landscape of Southern Karelia during the Spring Migration

Biology Bulletin, 2019
—Spring migrations of the Whooper swan and Bewick’s swan were studied on farmland near the town of Olonets during the years 1997–2017. Usually the majority of swans crosses the territory of the agricultural landscape in transit, and only a small portion ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐

An Integrated Remote Sensing and GIS Approach to Evaluating the Trade-offs Between Solar Energy Deployment, Land Use, and Carbon Storage Potential

Journal of Applied Science and Engineering
This study evaluates the trade-offs between solar photovoltaic (PV) deployment, land-use change, and vegetation carbon storage in Taiwan. Satellite imagery and official land-use datasets were used as primary data sources, while Geographic Information ...
