Review of hybrid and opaque scintillator technologies advancing neutrino and dark matter detectors

Stefan Schoppmann

Organic liquid scintillators are used since several decades, especially in neutrino physics. They excel at the detection of low-energy particles where energy and timing information is required. Organic liquid scintillators have advantages such as high light yield, radio purity, cost effectiveness, and more. However, th...

Labeled plane trees and increasing plane trees

Lora R. Du · Kathy Q. Ji · Dax T.X. Zhang

The main aim of this paper is to establish a polynomial analogue of $(n+1)!C_n=2^n(2n-1)!!$ (with $C_n$ as the $n$-th Catalan number) in the setting of labeled plane trees and increasing plane trees. This analogue is formulated in terms of improper edges of labeled plane trees and yields explicit formulas for the gener...

Alternaria and Fusarium across malting barley process: a comprehensive study of mycotoxins and quality effects

Eliana Castañares · Maria Inés Dinolfo · Carolina Manno · Verónica Conti · y 5 más

This study aimed to evaluate the incidence and biomass of Alternaria and Fusarium and their mycotoxins during the malting process, as well as their impact on barley grains and malt quality. Barley samples from different geographical regions of Argentina and two genotypes were subjected to micro-malting. Mycotoxins were...

Structural and metal ions gradients in Bacillus subtilis biofilms.

Mnar GHRAYEB · Ricardo SANTANDER GUALDRON · Remi TUCOULOU TACHOUERES · Liraz CHAI · y 2 más

Biofilms are groups of microbial cells that aggregate on surfaces and Interfaces. The cells in a biofilm are encased in an Extracellular Matrix (ECM) that serves as a shield for the cells from antibiotic activity. The ECM is a network of biopolymers, mainly polysaccharides and proteins, which composes more than 90% of...

Probing magnons of CaKFe4As4 superconductor

Nicholas BROOKES · Flora YAKHOU-HARRIS · Marli DOS REIS CANTARINO · RACHEL NICKEL · y 1 más

CaKFe4As4 is a hybrid iron superconductor between CaFe2As2 and KFe2As2 that acts like an ordered hole-doped material for the AeFe2As2 (Ae = alkaline earth) parent compound. Unlike hole-doped (Ba1–xKx)Fe2As2 (K-BFA), Ca and K do not occupy crystallographically equivalent sites because of the large differences in their i...

Characterization of glycosaminoglycan interactions with the chemokine CCL20 (MIP3α) and its carboxyterminal antimicrobial and antibiofilm peptide

Gopal, Ramamourthy · Hiroaki, Ishida · Hans J, Vogel

The chemokine CCL20/MIP3α plays an important role in the migration of dendritic cells and several lymphocytes. This 70-residue protein is also implicated in various diseases, such as rheumatoid arthritis, psoriasis, sepsis and numerous forms of cancer. In addition, as the most basic human chemokine, CCL20 also displays...

The structure of pharmaceuticals subjected to cryo-milling and compression

Joanna GRELSKA · Taoufik LAMRANI · Karolina JURKIEWICZ · Andy FITCH

The dosage of pharmaceuticals produced in non-crystalline phases, such as nanoparticles or glasses, has a great advantage due to their better bioavailability and solubility than crystalline counterparts. The modification of pharmaceutical by mechanical perturbation, e.g., milling or compaction, may lead to the desired...
