Improving the resilience of urban transportation to natural disasters: the case of Changchun, China.

This study quantitatively assesses the resilience of the urban transport system in Changchun under extreme climatic conditions, focusing on the impacts of natural disasters such as snowstorms, strong winds and extreme low temperatures on the transport system. The vulnerability, exposure, and emergency recovery capacity of the transport system in Changchun were analyzed by constructing a comprehensive assessment framework combining multi-criteria decision analysis (MCDM) and geographic information system (GIS). Based on the meteorological and traffic data of Changchun City in the past 10 years, key indicators such as traffic network density, emergency resource distribution, traffic flow, and extreme weather frequency were selected in this study.

Novel and efficient yeast-based strategies for subunit vaccine delivery against COVID-19.

Yeast shows promise as a delivery system for drugs and vaccines due to its specific targeting and immunogenic properties. The objective of this research is to create novel and effective yeast-based methods for delivering subunit vaccines. Through the modification of yeast expression plasmids and optimization of expression techniques, a new dual-expression system has been developed.

A stable zeolite with atomically ordered and interconnected mesopore channel.

Zeolites are crystalline microporous materials constructed by corner-sharing tetrahedra (SiO and AlO), with many industrial applications as ion exchangers, adsorbents and heterogeneous catalysts. However, the presence of micropores impedes the use of zeolites in areas dealing with bulky substrates. Introducing extrinsic mesopores, that is, intercrystal/intracrystal mesopores, in zeolites is a solution to overcome the diffusion barrier.

Dynamic Release Electrolyte Design for Stable Proton Batteries.

Aqueous proton batteries (APBs) have recently demonstrated unprecedented advantages in the fields of ultralow temperature and high-power energy applications due to kinetically favorable proton chemistry. Proton acids (e. g.

Association of joint exposure to organophosphorus flame retardants and phthalate acid esters with gestational diabetes mellitus: a nested case-control study.

Background: Organic phosphate flame retardants (OPFRs) and phthalate acid esters (PAEs) are common endocrine-disrupting chemicals that cause metabolic disorders. This study aimed to assess the association between joint exposure to OPFRs and PAEs during early pregnancy in women with gestational diabetes mellitus (GDM).

Methods: Seven OPFRs and five PAEs were detected in the urine of 65 GDM patients and 100 controls using gas chromatography-tandem triple quadrupole mass spectrometry (GC-MS).
