We present a new method for the a priori approximation of the orders of magnitude of the entries in the LU factors of a complex or real matrix A. This approximation is used to determine the positions of the largest entries in...

Crystallization of perovskite structure chromites (ACrO3) in aqueous conditions is difficult owing to the amphoteric nature of the Cr3+ in the alkaline-mediated reaction conditions. This is especially true for the small metal...
In his July 1984 interview with Michael Cooke, W. H. Winborne described his work with the Orangeburg Area Sickle Cell Anemia Foundation, the Family Health Center, and the outreach programs related to the foundation. Winborne...
Many studies have shown that urban workers may have a higher acceptance rate of coronavirus disease (COVID-19) vaccine uptake compared to their rural counterparts. As Omicron spreads globally, the COVID-19 booster vaccination...
The first example of enantioselective S‐H insertion reactions of sulfoxonium ylides is reported. Under the influence of thiourea catalysis, excellent levels of enantiocontrol (up to 95% ee) and yields (up to 97%) are achieved...

Abstract: Searches for CP violation in the two-body decays Ds+→h+π0 and Ds+→h+η (where h+ denotes a π+ or K+ meson) are performed using pp collision data collected by the LHCb experiment corresponding to either 9 fb−1 or 6 fb−1...
BACKGROUND: 6-[Bis(carboxymethyl)amino]-1,4-bis(carboxymethyl)-6-methyl-1,4-diazepane (AAZTA ) is a promising chelator with potential advantages over 1,4,7,10-tetraazacyclododecane-1,4,7,10-tetraacetic acid (DOTA) for...
The neutral hydrogen (H I) content of dark matter haloes forms an intermediate state in the baryon cycle that connects the hot shock-heated gas and cold star-forming gas in haloes. Measurement of the relationship between H I...

Searches for $CP$ violation in the two-body decays $D_{(s)}^{+}\rightarrow
h^{+}\pi^{0}$ and $D_{(s)}^{+} \rightarrow h^{+}\eta$ (where $h^{+}$ denotes a
$\pi^{+}$ or $K^{+}$ meson) are performed using $pp$ collision data...
RATIONALE: Pulmonary arterial hypertension (PAH) is characterized by excessive proliferation and apoptosis resistance in pulmonary artery smooth muscle cells (PASMCs). OBJECTIVE: We reasoned that chloroquine, based on its...
Data deposited in the Cambridge Structural Database (CSD) for compounds of scandium, yttrium, lanthanum and lutetium(III) have been analysed to assess the structural similarities of complexes of the different metal ions. 29 sets...
The direct synthesis of hydrogen peroxide (H2O2) from H2 and O2 represents a potentially atom-efficient alternative to the current industrial indirect process. We show that the...
Herein, we report the ruthenium-catalyzed ortho C–H alkenylation of a wide range of N-aryloxazolidinone scaffolds. Alkenylation was achieved with complete monoselectivity with a scope of 27 examples in 2-MeTHF. Yields ranged...
High-temperature superconductor (HTS) bulks have shown very promising potential for industrial applications due to the ability to trap much higher magnetic fields compared to traditional permanent magnets. In rotating...

This collected volume is written in honour of Allen G. Debus (1926–2009), the famous historian of science. Trained as a chemist, his interest in the history of science and chemistry would guide his research and his output. As...
Acute respiratory infections (ARIs) impose a major public health burden on fragile healthcare systems of developing Southeast Asian countries such as Vietnam. The epidemiology, genetic diversity and transmission patterns of...
Superionic states simultaneously exhibit properties of a fluid and a solid. Proton (H+) superionicity in ice, H3O, He-H2O, and He-NH3 compounds is well-studied. However, hydride (H-) superionicity in H-rich compounds is rare...
A study of the charge conjugation and parity (CP) properties of the interaction between the Higgs boson and top quarks is presented. Higgs bosons are identified via the diphoton decay channel (H→γγ), and their production in...
