Research on Precise Identification of Rock Strength Based on Bolt Drilling Parameters

open access: yesEnergy Science &Engineering, EarlyView.
Drilling detection test platform. ABSTRACT During roadway excavation, the presence of weak interlayers and fractured rock masses significantly affects roof stability. To achieve timely and effective roadway support, it is crucial to identify and predict different rock types based on drilling signals from roof bolters.

Tracing large-scale structures in circumstellar disks with ALMA

open access: yes, 2012
Planets are supposed to form in circumstellar disks. The gravitational potential of a planet perturbs the disk and leads to characteristic structures, i.e. spiral waves and gaps, in the disk's density profile.

Reintroducing the Gray Wolf.

open access: yes, 2020
Earlier this month, the citizens of Colorado passed Proposition 114, a measure that reintroduces gray wolves into the local ecosystem. The measure involves a plan to reintegrate the wolves by the end of 2023. It passed with 50.4% of votes in support and 49.6% in opposition; it was quite controversial.

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

Previable PROM in twins: A systematic review and meta‐analysis

open access: yesInternational Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background Previable prelabor rupture of membranes (PROM) in twin pregnancies is a rare but high‐risk condition associated with substantial neonatal mortality and maternal morbidity. Management options include expectant management and selective reduction, though guidance is limited and based primarily on singleton data.
