Recharge coefficients and recharge mechanisms of precipitation to groundwater in karst areas of North China: A case study of Yangzhuang karst water system

地质科技通报
Objective To establish a series of hydrogeological parameter for karst areas in North China, an on-site experimental study on water balance has been carried out since the 1980s in a closed spring-drainage karst water system in Yangzhuang, Shandong ...

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‐

Methane emissions respond slowly to changes in soil water table depth in contrast to carbon dioxide emissions

Environmental Research Communications
We present results from two sets of soil mesocosm experiments designed to explore the impact of changes in water table depth on methane (CH _4 ) and carbon dioxide (CO _2 ) emissions. In all experiments, soils were initially drained, as they are in situ .

Peatland Water Table Depth Monitoring Using Quad-Polarimetric L-Band SAR

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing
Accurate, remote sensing-based methods of monitoring peatland water table depth (WTD) could support peatland management and restoration. Quad-polarimetric L-band synthetic-aperture radar (quad-pol L-band SAR) imagery has potential advantages over other ...

Pharmacological inhibition of the PERK pathway modulates hepatocellular carcinoma growth and immune signaling

FEBS Open Bio, EarlyView.
Pharmacological inhibition of PERK in a DEN‐induced mouse model of liver cancer does not reduce tumor burden but alters cellular stress signaling. Despite blocking PERK activity, downstream stress responses, including CHOP expression, remain active, suggesting compensatory mechanisms within the unfolded protein response that may influence tumor ...

Steady Water Flow with Interacting Point Source–Point Sink–Water Table in a Cylindrical Soil Domain

Vadose Zone Journal, 2019
A previously derived analytical solution to the quasi-linear form of the water flow equation is used to analyze (i) steady, coupled plant water uptake from a surface water emitter in a confined cylindrical soil domain with a non-evaporating surface in ...

High Resolution Water Table Modeling of the Shallow Groundwater Using a Knowledge-Guided Gradient Boosting Decision Tree Model

Frontiers in Water, 2021
Detailed knowledge of the uppermost water table representing the shallow groundwater system is critical in order to address societal challenges that relate to the mitigation and adaptation to climate change and enhancing climate resilience in general ...

Early‐life high‐fat diet exposure increases Achilles tendon stiffness and induces transcriptomic alterations

FEBS Open Bio, EarlyView.
Early‐life exposure to a high‐fat diet altered intact Achilles tendons in rat offspring, making them thinner, stiffer, and molecularly distinct even without injury. These findings suggest that developmental high‐fat diet exposure may impair tendon quality and increase susceptibility to mechanical overload or tendon injury later in life.

Effects of water-table depth on seed quality as β-glucan content in waxy and non-waxy naked barley grains

Plant Production Science
Naked barley (Hordeum vulgare L.) is often planted as a regional specialty crop in the western region of Japan, where there are many hilly and mountainous areas.
