Abstract A two-dimensional version of the Pennsylvania State University mesoscale model has been applied to Winter Monsoon Experiment data in order to simulate the diurnally occurring convection observed over the South China Sea. The domain includes a representation of part of Borneo as well as the sea so that the model can simulate the initiation of convection. Also included in the model are parameterizations of mesoscale ice phase and moisture processes and longwave and shortwave radiation with a diurnal cycle. This allows use of the model to test the relative importance of various heating mechanisms to the stratiform cloud deck, which typically occupies several hundred kilometers of the domain. Frank and Cohen's cumulus parameterization scheme is employed to represent vital unresolved vertical transports in the convective area. The major conclusions are: Ice phase processes are important in determining the level of maximum large-scale heating and vertical motion because there is a strong anvil componen...

Numerical study of convection observed during the Winter Monsoon Experiment using a mesoscale two-dimensional model [presentation]

Fluorescent carbon nanoparticles or carbon quantum dots (CQDs) are a new class of carbon nanomaterials that have emerged recently and have garnered much interest as potential competitors to conventional semiconductor quantum dots. In addition to their comparable optical properties, CQDs have the desired advantages of low toxicity, environmental friendliness low cost and simple synthetic routes. Moreover, surface passivation and functionalization of CQDs allow for the control of their physicochemical properties. Since their discovery, CQDs have found many applications in the fields of chemical sensing, biosensing, bioimaging, nanomedicine, photocatalysis and electrocatalysis. This article reviews the progress in the research and development of CQDs with an emphasis on their synthesis, functionalization and technical applications along with some discussion on challenges and perspectives in this exciting and promising field.

Carbon quantum dots and their applications

Purpose – The purpose of this paper is to explore the psychological mechanisms explaining the impact of fit on burnout based on meta-theories. Design/methodology/approach – A total of 199 employees participated in three waves with three-week intervals. Person-organization fit and person-job fit were measured in Wave 1, psychological-mechanism variables were measured in Wave 2, and burnout was measured in Wave 3. Findings – Person-organization fit and person-job fit related to three components of job burnout via multiple psychological mechanisms. Research limitations/implications – The findings help to extend existing theories on fit and burnout literature. The research advances the understanding of psychological mechanisms about how misfit leads to job burnout. It helps stimulate research interest to further investigation on their relationships and effects with other variables besides burnout. It also helps understand the construct of burnout. Practical implications – For individuals, person-job fit shoul...

Although extensive research has been conducted to investigate various factors related to organizational justice, few studies have examined the link between personality traits and organizational justice. Using a field sample, we explored the relationships between the five-factor model of personality and organizational justice. Results indicated that agreeableness and neuroticism were important correlates of organizational justice. Specifically, agreeableness was found to be positively related to all four organizational justice components proposed by Colquitt (2001). Neuroticism was found to be negatively related to procedural justice and informational justice. Theoretical and practical implications of the results are discussed.

Linking the Big Five personality constructs to organizational justice

SARS-CoV-2 recombinant subvariant XBB.1.5 is growing rapidly in the United States, carrying an additional Ser486Pro substitution compared to XBB.1 and outcompeting BQ.1.1 and other XBB sublineages. The underlying mechanism for such high transmissibility remains unclear. Here we show that XBB.1.5 exhibits a substantially higher hACE2-binding affinity compared to BQ.1.1 and XBB/XBB.1. Convalescent plasma samples from BA.1, BA.5, and BF.7 breakthrough infection are significantly evaded by both XBB.1 and XBB.1.5, with XBB.1.5 displaying slightly weaker immune evasion capability than XBB.1. Evusheld and Bebtelovimab could not neutralize XBB.1/XBB.1.5, while Sotrovimab remains weakly reactive and notably, SA55 is still highly effective. The fact that XBB.1 and XBB.1.5 showed comparable antibody evasion but distinct transmissibility suggests enhanced receptor-binding affinity would indeed lead to higher growth advantages. The strong hACE2 binding of XBB.1.5 could also enable its tolerance of further immune escape mutations, which should be closely monitored.
