Introducing intense rainfall and snowmelt variables to implement a process-related non-stationary shallow landslide susceptibility analysis.

Sci Total Environ 2021 Apr 27;786:147360. Epub 2021 Apr 27.

Dipartimento di Scienze della Terra "A. Desio", Università degli Studi di Milano, Milan, Italy.

The study objective was to derive a susceptibility model for shallow landslides that could include process-related non-stationary variables, to be adaptable to climate changes. We selected the territory of the Mont-Emilius and Mont-Cervin Mountain Communities (northern Italy) as the study area. To define summary variables related to landslide predisposing and triggering processes, we investigated the relationships between landslide occurrences and intense rainfall and snowmelt events (period 1991-2020).

Phys Rev Lett 2021 Apr;126(16):161802

Laboratoire Leprince-ringuet (llr), Palaiseau, France.

We present an angular analysis of the B^{+}→K^{*+}(→K_{S}^{0}π^{+})μ^{+}μ^{-} decay using 9  fb^{-1} of pp collision data collected with the LHCb experiment. For the first time, the full set of CP-averaged angular observables is measured in intervals of the dimuon invariant mass squared.

Photoperiod affects the laying performance of the mountain duck by regulating endocrine hormones and gene expression.

Vet Med Sci 2021 May 6. Epub 2021 May 6.

Guangdong Province Key Laboratory of Waterfowl Healthy Breeding, College of Animal Science and Technology, Zhongkai University of Agriculture and Engineering, Guangzhou, China.

Light mainly affects animal reproductive performance through the hypothalamus- pituitary-gonadal axis, but the specific regulating mechanism is not yet clear in duck. To reveal the effects of light on the laying performance of ducks and its possible regulatory mechanisms, Shanma ducks at 52 weeks age were divided into three group treated with different photoperiods of 16 hr (control group), 24 hr (long-photoperiod group, LP), and 8 hr (short-photoperiod group, SP). Laying performance, endocrine-related hormones and gene expression of three groups were compared. Read More

Lessons on Mass Gatherings Learned From the 2019 Union Cycliste Internationale Mountain Bike World Cup.

Cureus 2021 Apr 3;13(4):e14275. Epub 2021 Apr 3.

Emergency Medicine, West Virginia University School of Medicine, Morgantown, USA.

The Union Cycliste Internationale (UCI) Mountain Bike World Cup in 2019 provided unique challenges for effective prehospital care. While on-site medical care has demonstrated improved outcomes along with reduced emergency department and emergency medical services (EMS) utilization, this aspect has not been well documented in the literature with respect to rural mass gathering events (MGEs). Conducted at a large mass gathering event in a geographically isolated area, this study aimed to assess the medical needs at this specific event and will hopefully assist in future coordination of similar events.

Department of Microbiology and Immunology, School of Medicine, University of Maryland Baltimore, Maryland, USA.

Species of (: ) are obligate intracellular parasites of a wide range of eukaryotes, with recognized arthropod-borne human pathogens belonging to the transitional group (TRG), typhus group (TG), and spotted fever group (SFG) rickettsiae. Growing in the host cytosol, rickettsiae pilfer numerous metabolites to make a typical Gram-negative bacterial cell envelope. The O-antigen of rickettsial lipopolysaccharide (LPS) is immunogenic and has been shown to tether the S-layer to the rickettsial surface; however, little is known about the structure and immunogenicity of the lipid A moiety.
