Fracture evolution of a thick soft protection layer and the water inrush mechanism in overburden under longwall mining

Deep Underground Science and Engineering, EarlyView.
Through shear–tensile creep tests and viscoelastic modeling, the fracture evolution of thick soft protective layers is clarified. Results show thickness‐dependent rheological failure modes that govern four types of roof water inrush, providing a mechanism‐based framework for hazard prediction and control. Abstract In the Jurassic coal‐bearing strata of

Effects of Scape Removal Position on Nutrient Allocation, Yield, and Quality of Garlic (Allium sativum L.)

HortScience
The removal of garlic scapes requires substantial manual labor. Failure to remove scapes or improper scape removal positions may adversely affect bulb development.

T2 plants with normal bolting time are transgene-free plants.

, 2019
DNA was isolated from leaves collected from 4–6 individual normal bolting T2 plants for each of the 4 lines, and PCR was used to amplify Cas9 fragment.

Shock wave propagation characteristics of aluminum‐containing explosive in corrugated steel‐lined tunnel

Deep Underground Science and Engineering, EarlyView.
Aluminum‐enhanced afterburning renders AE explosives more hazardous than conventional ones. Corrugated steel linings reduce far‐field AE blast overpressure by ~50% through wave reflection and dissipation. The developed model accurately predicts peak pressure (<10% error) and arrival time (<3% error), supporting protective design.

Early bolting phenotypes observed in the T1 and T2 transgenic plants.

, 2019
(A) Early bolting phenotype in some T1 transgenic plants. Transgenic plants were selected on antibiotic-containing 1/2 MS plates, and ~5-day-old transgenic seedlings were transferred into soil pots and grown in a growth room.

Investigation on the failure evolution characteristics of surrounding rock in deep cross‐fault roadway: Based on physical model test and numerical simulation

Deep Underground Science and Engineering, EarlyView.
This study reveals the failure evolution characteristics of deep cross‐fault roadway surrounding rock under excavation support and periodic weighting. Periodic weighting readily induces fault activation, with the spatial distribution of failed rock masses being controlled by the fault strike and dip.

Investigation on the mechanical behavior of the multiple‐layered lining structure of a water conveyance tunnel with high internal water pressure

Deep Underground Science and Engineering, EarlyView.
This study presents large‐scale similarity model testing (geometric ratio 3.6) of an innovative multiple‐layered lining system—comprising exterior precast segments, middle self‐compacting concrete, and an interior steel pipe—for high‐pressure (0.75 MPa) water conveyance tunnels.

Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

Deep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.

Integrative path modeling and QTL mapping identify maturity, stem strength, and cell wall composition driving lettuce resistance to Sclerotinia minor

Scientific Reports
Lettuce (Lactuca sativa) is highly vulnerable to Sclerotinia minor, the pathogen causing lettuce drop. Breeding for resistance is the most effective control strategy; however, full resistance has not been achieved, and current partial resistance sources ...
