Spatial deformation prediction method of fractured rock tunnel based on quantified GSI and its application.

Determining rock mass mechanical parameters and accurately predicting tunnel deformation during tunnel construction remain challenging tasks. This study introduces a novel approach to calculate the Geological Strength Index by integrating indoor rock mechanics tests with geometric data from three-dimensional dense reconstruction. We utilized the Hoek-Brown strength criterion to develop a theoretical model for predicting tunnel deformation in fractured rock masses.

Soil bacterial communities associated with marbled fruit in Blanco 'Orah'.

Blanco 'Orah' is grown throughout southern China and provides enormous economic value. However, the agricultural industry has suffered substantial losses during recent years due to marbled fruit disease. The present study focuses on the soil bacterial communities associated with marbled fruit in 'Orah'.

Preventive therapeutic effect of Lactobacillus-fermented black wolfberry juice on sodium dextran sulfate-induced ulcerative colitis in mice.

In this study, male mice were treated with fermented and unfermented Lactobacillus plantarum, Lactobacillus bulgaricus, and Lactobacillus rhamnosus black wolfberry juice (10 mL/kg/day) for 40 days, and their prophylactic effects on ulcerative colitis (UC) induced by dextran sodium sulfate were investigated. The intervention of black wolfberry juice reduced the levels of pro-inflammatory cytokines and increased the content of anti-inflammatory cytokines in the serum and colon. In addition, the pathological changes in colon tissue were alleviated, the expression of Bcl-2 protein in the colon was enhanced, and the intestinal microbiota of the mice was regulated, with an increase in Bacteroidetes and a decrease in Helicobacter.

Nonintrusive Monitoring of Mental Fatigue Status Using Epidermal Electronic Systems and Machine-Learning Algorithms.

Mental fatigue, characterized by subjective feelings of "tiredness" and "lack of energy", can degrade individual performance in a variety of situations, for example, in motor vehicle driving or while performing surgery. Thus, a method for nonintrusive monitoring of mental fatigue status is urgently needed. Recent research shows that physiological signal-based fatigue-classification methods using wearable electronics can be sufficiently accurate; by contrast, rigid, bulky devices constrain the behavior of those wearing them, potentially interfering with test signals.

Precise Engineering of Conductive Pathway by Frictional Direct-Writing for Ultrasensitive Flexible Strain Sensors.

Highly sensitive strain sensors that can detect small strain are in high demand in the fields of displays, robotics, fatigue detection, body monitoring, in vitro diagnostics, and advanced therapies. However, resistive-type sensors that are composed of electrically conductive sensing films coupled with flexible substrates suffer from the limits that their gauge factors (GFs) at small strains (e.g.
