Fraternal Twins: Syntheses and Crystal Structures of Yb11O2(OH)[AsO3]8[As2O5] and Lu6O[AsO3]4[As2O5]
The complex triclinic structure of Yb11O2(OH)[AsO3]8[As2O5] crystallizes in P1 (a = 843.81(6), b = 841.32(6), c = 1236.40(8) pm, α = 76.759(2), β = 71.726(2), γ = 85.347(2)°; Z = 1). The triclinic Lu6O[AsO3]4[As2O5] (P1¯$\overline{1}$; a = 836.72(6), b = 849.45(6), c = 1344.51(9) pm, α = 81.078(2), β = 85.289(2), γ = 86.034(2)°; Z = 2) can also be ...

Abstract Unsustainable hunting practices can alter population dynamics, driving biodiversity declines, which leads to ‘empty forests’. Understanding hunting behaviour, including motivations for hunting and relationships with market drivers, and access to hunting grounds are important to develop affirmative policies to stem biodiversity loss.

Abstract Volunteers have been involved in nature observations for decades through citizen science initiatives, providing large data sets as well as problem identification that allow a more complete understanding of many natural phenomena. Although communication is a core component in citizen science, the key factors that determine its effectiveness in ...

The continuing significance of chiral agrochemicals
In the time frame 2018–2023, around 43% of the 35 chiral agrochemicals introduced to the market (herbicides, fungicides, insecticides, acaricides, and nematicides) contain one or more stereogenic centers in the molecule, and almost 69% of them have been marketed as racemic mixtures of enantiomers or stereoisomers.

Multi‐level fatigue reliability assessment of reinforced concrete railway bridges
Abstract This paper presents a multi‐level reliability framework for assessing the fatigue life of reinforced concrete (RC) railway trough bridges subjected to cyclic loading. The framework incorporates increasing levels of analytical complexity and real‐world data in four steps. First, an analytical model applies S–N curves and the Palmgren–Miner rule

Abstract This study investigates the numerical modeling of internal tendon breaks in prestressed concrete structures and evaluates the key parameters affecting accuracy. A combined approach is followed, involving global sensitivity analysis via the Elementary Effects Method and subsequent model calibration using experimental data from distributed fiber‐

Abstract Based on an analysis of the Old Literary Tibetan corpus—a corpus of the oldest documented Tibetic language—the present study provides evidence that literary Tibetan v3 verb stems (commonly termed ‘future’) initially encoded passive voice. New arguments put forward in this article range from Trans‐Himalayan nominal morphology to early Tibetan ...
