Failure Law of Soft and Hard Interlayer Overlying Rock in Gently Inclined, Super‐Thick Coal Seam and Research on the Development Height of a Water‐Conducting Fissure Zone

open access: yesEnergy Science &Engineering, EarlyView.
Based on the layered structural characteristics of the strata, this study summarizes four typical overburden structural types under the geological conditions of the 51408 working face. Through theoretical derivation and numerical simulation, the study reveals the stepwise failure characteristics of the overburden and analyzes the variations in ...

A path to reconciliation between Indigenous and settler–colonial epistemologies

open access: yesFrontiers in Ecology and the Environment, EarlyView.
There is a movement across settler–colonial institutions of education and research to engage with Indigenous Peoples and Knowledges. Many settler and Indigenous governments are pursuing pathways to move forward together to address global problems such as climate change. However, given the pervasive history of exploitation and displacement of Indigenous

Li16Sr6Ge6N, Li16Sr6Ge6.5 and related lithium alkaline‐earth metal tetrelides: Alternative filling of voids by nitride or tetrelide ions

open access: yesZeitschrift für anorganische und allgemeine Chemie, Volume 648, Issue 23, December 13, 2022., 2022
Abstract Large black single crystals with a metallic luster of Li16Sr6Ge6N and several other representatives of the series Li16Ae6Tt6N and Li16Ae6Tt6.5 (Ae=Ca, Sr; Tt=Si, Ge, Sn, Pb) were grown from mixtures of the respective elements with addition of binary alkaline‐earth metal nitrides or lithium nitride in the case of the nitrides. For the synthesis

“Tension Chyle Leak”: A Life‐Threatening Sequela of Thoracic Duct Injury Following Resection of BRAF‐Mutated Anaplastic Thyroid Carcinoma

open access: yesHead &Neck, EarlyView.
ABSTRACT Background Airway obstruction secondary to chyle leak is an exceptionally rare phenomenon. Here, we describe this complication in a patient with anaplastic thyroid carcinoma (ATC) undergoing consolidative surgery after BRAF‐targeted therapy. Methods A 55‐year‐old man presented with a rapidly enlarging neck mass.

2019 Mw 6.0 Mesetas (Colombia) Earthquake Sequence: Insights From Integrating Seismic and Morphostructural Observations

open access: yesEarth and Space Science, Volume 9, Issue 12, December 2022., 2022
Abstract The boundary between the Northern Andean block and the South American plate is a first‐order tectonic structure in Colombia with historically M > 7 earthquakes. However, details about individual sections of the system remain unknown. We illuminate the seismotectonic of the Algeciras fault by investigating an earthquake sequence that started on

Intramolecular Phenyl Transfer from Boron to Lithium, Sodium, and Copper: Defining the Limits of Transmetalation

open access: yesHelvetica Chimica Acta, Accepted Article.
Transmetalation is a key elementary step in organometallic chemistry, for which reason there is a keen interest in better understanding the factors governing this reaction. We have previously reported the unusual transfer of a phenyl anion from boron to lithium in the gas‐phase dissociation of [LiBr(tBu)(Ph)Bpin]− (Chem. Eur.

Predefined‐time distributed event‐triggered algorithms for resource allocation

open access: yesIET Cyber-Physical Systems: Theory &Applications, Volume 7, Issue 4, Page 183-196, December 2022., 2022
This paper considers the distributed resource allocation problem over an undirected multi‐agent system by proposing a predefined‐time distributed algorithm. Furthermore, to reduce the communication burden, the static and dynamic event‐triggered mechanisms are provided.
