The impact of China's low-carbon policies' intensity on the labor demand of listed companies.

This study examines the impact of China's low-carbon policies on labor demand in listed firms, focusing on command-and-control and market-based instruments. The research integrates a comprehensive dataset spanning 2007 to 2016, comprising employment and financial data, alongside an analysis of low-carbon policy intensity from 2007 to 2022. Results from fixed-effects panel data regression indicate that both types of policies positively influence labor demand, with command-and-control policies exhibiting a slightly stronger effect.

Phase Transition of α-MgPO at High-Pressure and High-Temperature Conditions: The Third Polymorph of MgPO.

MgPO has two known polymorphs, i.e., α- and β-phase, at low and high temperatures, respectively.

WBC Image Segmentation Based on Residual Networks and Attentional Mechanisms.

White blood cell (WBC) morphology examination plays a crucial role in diagnosing many diseases. One of the most important steps in WBC morphology analysis is WBC image segmentation, which remains a challenging task. To address the problems of low segmentation accuracy caused by color similarity, uneven brightness, and irregular boundary between WBC regions and the background, a WBC image segmentation network based on U-Net combining residual networks and attention mechanism was proposed.

Spatio-temporal variation of ozone pollution risk and its influencing factors in China based on Geodetector and Geospatial models.

Ozone (O) has become the primary pollutant in many cities, and high concentrations of O cause significant harm to the ecological environment and human health. This study investigated the spatiotemporal distribution of surface concentrations of ozone over entire China and analyzed the influencing factors based on the geographical detector technique. Moreover, the Pearson correlation analysis was used to analyze the influence of various meteorological factors on ozone concentrations.

A base-mediated aerobic oxidative synthesis of cyclopent-2-enol derivatives from doubly activated cyclopropanes and substituted acetonitriles.

We report here that polysubstituted cyclopent-2-enols can be constructed by the one-pot reaction of doubly activated cyclopropanes and α-EWG substituted acetonitriles under mild basic conditions a domino-ring-opening-cyclization/deacylation/oxidation sequence. Moreover, the synthetic applications of these cyclopent-2-enols have been demonstrated in the late-stage derivatization into functionalized cyclopentapyrimidin-4-ones and 2-hydroxy cyclopentanones with good yields.

Effects of Hydrogen Multijet and Flow Rate Assignment on the Combustion Flow Characteristics in a Jet-Stabilized Combustor.

In this study, a hydrogen fuel jet-stabilized combustor is proposed, the combustion flow characteristics are numerically investigated under the conditions of three equivalence ratios (1, 0.37, and 0.22), and the effects of hydrogen flow rate assignment on the combustion flow are also analyzed.

Comparison of Trust Assessment Scales Based on Item Response Theory.

Three widely used interpersonal trust measurement scales [Interpersonal Trust Scale (ITS), Philosophies of Human Nature Scale (RPHNS), Company Trust Scale (CTS)] have seldom been applied in non-Western contexts. Different social environments may lead to variation in the level or structure of trust. Therefore, it is necessary to compare the applicability of these scales to different levels of trust-related traits in Eastern cultures so that researchers can choose appropriate scales for relevant studies.

Classifying Multifunctional Enzymes by Incorporating Three Different Models into Chou's General Pseudo Amino Acid Composition.

With the avalanche of the newly found protein sequences in the post-genomic epoch, there is an increasing trend for annotating a number of newly discovered enzyme sequences. Among the various proteins, enzyme was considered as the one of the largest kind of proteins. It takes part in most of the biochemical reactions and plays a key role in metabolic pathways.
