REACH story of change: cleaning the tap: tap hygiene for safer drinking water by REACH

“…Evidence from Bangladesh suggests that regular cleaning of water point spouts and taps could substantially reduce this figure, even halving the number of contaminated handpumps.</p> <p>• Based on this evidence, new WHO guidance on Sanitary Inspections includes cleaning of handpump spouts for the first time. …”

A comparison of methods for forecasting value at risk and expected shortfall of cryptocurrencies by Trucíos, C, Taylor, JW

“…Those procedures are revisited in this paper, and their value at risk and expected shortfall forecasting performance are evaluated using recent Bitcoin and Ethereum data that include periods of turbulence due to the COVID-19 pandemic, the third halving of Bitcoin, and the Lexia class action. Additionally, in order to mitigate the influence of model misspecification and enhance the forecasting performance obtained by individual models, we evaluate the use of several forecast combining strategies. …”

Bisections of Mass Assignments Using Flags of Affine Spaces by Axelrod-Freed, Ilani, Soberón, Pablo

“…We also study the problem of halving several families of (𝑑−𝑘) -dimensional affine spaces of ℝ𝑑 using a (𝑘−1) -dimensional affine subspace contained in some translate of a fixed k-dimensional affine space. …”

Highly stretchable, elastic, and ionic conductive hydrogel for artificial soft electronics by Zhou, Yang, Wan, Changjin, Yang, Yongsheng, Yang, Hui, Wang, Shancheng, Dai, Zhendong, Ji, Keju, Jiang, Hui, Chen, Xiaodong, Long, Yi

“…The proposed ionic conductive hydrogel is achieved by physically cross-linking the tough biocompatible polyvinyl alcohol (PVA) gel as the matrix and embedding hydroxypropyl cellulose (HPC) biopolymer fibers inside matrix followed by salt solution soaking. The wrinkle and dense structure induced by salting in PVA matrix provides large stress (1.3 MPa) and strain (975%). …”

Thermally induced phase separation PVDF membrane fabricated by using NaCl coagulation bath: relation of membrane surface morphology and permeation performance by Chen, Ningyuan, Zhao, Jie, Shi, Lei, Goto, Atsushi, Wang, Rong

“…The inclusion of NaCl in the coagulation bath serves to decrease the solubility of PEG within this medium, owing to the salting-out effect. Consequently, the NaCl concentration in the coagulation bath emerges as a crucial factor in regulating the migration of PEG400 toward the membrane surface. …”

Simulation study of semiconductor thermoelectric power generator for waste heat recovery and energy harvesting by Chan, Murphy Kim Hua

“…One of the proven initiatives is to perform waste heat recovery using thermoelectric generators (TEGs) in wide variety of applications including space, solar photovoltaic, automotive, smelting and more. To understand key aspects of TEG performances such as power output and efficiency, the study of thermoelectric material with respect to applied temperature is also another important consideration. …”

Correlation between GNSS-TEC and eruption magnitude supports the use of ionospheric sensing to complement volcanic hazard assessment by Manta, Fabio, Occhipinti, Giovanni, Hill, Emma M., Perttu, Anna, Assink, Jelle, Taisne, Benoit

“…Moderate correlation between IVPI and peak ground velocity (PGV) requires further study in order to evaluate the role of different parameters (seismic magnitude, attenuation, style of faulting, crustal structure, etc.). Our results suggest that ionospheric monitoring by GNSS TEC can help to characterize volcanic eruptions, opening new exciting avenues for continuous volcano monitoring and warning systems by remote sensing.…”

Studies of seed-borne fungi of tropical pasture legume species by Nik, WZ, Parbery, DG

“…In order to isolate storage fungi, seeds were incubated on salt-malt agar. This medium was also effective in isolating pathogens which survived for long periods in seed, which suggests that such pathogens may share with storage fungi physiological characteristics which aid survival in seed. …”

A tale of two shuffle algebras by Neguț, Andrei

“…As a quantum affinization, the quantum toroidal algebra 𝑈𝑞,𝑞⎯⎯⎯(𝔤𝔩¨𝑛) is defined in terms of its “left” and “right” halves, which both admit shuffle algebra presentations (Enriquez in Transform Groups 5(2):111–120, 2000; Feigin and Odesskii in Am Math Soc Transl Ser 2:185, 1998). …”
