The Effects Of Orography On Wind, Cloud, And Rainfall Patterns During Typhoon Ketsana (2009)
Understanding the orographic effect is crucial for both disaster prevention and weather prediction for events such as tropical cyclones (TCs). Because of the complexity of orographic effects, due to the presence of mountains, the influence of orography on TCs remains unclear and is an active area of scientific research. The objective of this study is to investigate the effects of orography on the rainfall, wind, and cloud systems of the TCs in Malaysia, as this type of study has never been performed in Malaysia

Kesan pembakaran dan pencemaran ke atas Asia Tenggara (SEA) adalah kebimbangan besar kepada penyelidik perubahan iklim global. Lokasi geografi, topografi dan faktor-faktor meteorologi yang mempengaruhi cuaca SEA semuanya menyumbang kepada kerumitan sistem aerosol di seluruh dunia.
The impact of biomass burning and pollution on Southeast Asia (SEA) is of considerable concern to global climate change researchers. Geographical location, topography and meteorological factors affecting SEA all contribute to the complexity of the aerosols system worldwide
Global existence and temporal decay for the 3D compressible Hall-magnetohydrodynamic system
In this paper, we are concerned with the 3D compressible Hall-magnetohydrodynamic system in the whole space. We prove the global existence and temporal decay rates of the solutions to the system when the initial data are close to a stable equilibrium state by using a pure energy method
System biology analysis reveals the role of voltage-dependent anion channel in mitochondrial dysfunction during non-alcoholic fatty liver disease progression into hepatocellular carcinoma
Non-alcoholic fatty liver disease (NAFLD) is one of the most common causes of hepatocellular carcinoma (HCC), but the underlying mechanisms behind the correlation of NAFLD with HCC are unclear. We aimed to uncover the genes and potential mechanisms that drive this progression. This study uncovered the genes and potential mechanisms through a multiple 'omics integration approach. Quantitative proteomics combined with phenotype-association analysis was performed. To investigate the potential mechanisms, a comprehensive transcriptome/lipidome/phenome-wide association analysis was performed in genetic reference panel BXD mice strains. The quantitative proteomics combined with phenotype-association results showed that VDAC1 was significantly increased in tumor tissues and correlated with NAFLD-related traits. Gene co-expression network analysis indicated that VDAC1 is involved in mitochondria dysfunction in the tumorigenic/tumor progression. The association between VDAC1 and mitochondria dysfunction can be explained by the fact that VDAC1 was associated with mitochondria membrane lipids cardiolipin (CL) composition shift. VDAC1 was correlated with the suppression of mature specie CL(LLLL) and elevation level of nascent CL species. Such profiling shift was supported by the significant positive correlation between VDAC1 and PTPMT1, as well as negative correlation with CL remodeling enzyme Tafazzin (TAZ). This study confirmed that the expression of VADC1 was dysregulated in NAFLD-driven HCC and associated with NAFLD progression. The VDAC1-driven mitochondria dysfunction is associated with cardiolipin composition shift, which causes alteration of mitochondria membrane properties
Noncoordinating Flame-Retardant Functional Electrolyte Solvents for Rechargeable Lithium-Ion Batteries
In Li-ion batteries, functional cosolvents could significantly
improve the specific performance of the electrolyte, for example,
the flame retardancy. In case the cosolvent shows strong Li+-coordinating ability, it could adversely influence the electrochemical
Li+-intercalation reaction of the electrode. In this work,
a noncoordinating functional cosolvent was proposed to enrich the
functionality of the electrolyte while avoiding interference with
the Li storage process. Hexafluorocyclotriphosphazene, an efficient
flame-retardant agent with proper physicochemical properties, was
chosen as a cosolvent for preparing functional electrolytes. The nonpolar
phosphazene molecules with low electron-donating ability do not coordinate
with Li+ and thus are excluded from the primary solvation
sheath. In graphite-anode-based Li-ion batteries, the phosphazene
molecules do not cointercalate with Li+ into the graphite
lattice during the charging process, which helps to maintain integral
anode structure and interface and contributes to stable cycling. The
noncoordinating cosolvent was also applied to other types of electrode
materials and batteries, paving a new way for high-performance electrochemical
energy storage systems with customizable functions

An Overview of Mesoscale Aerosol Processes, Comparisons, and Validation Studies from DRAGON Networks
Over the past 24 years, the AErosol RObotic NETwork (AERONET) program has provided highly accurate remote-sensing characterization of aerosol optical and physical properties for an increasingly extensive geographic distribution including all continents and many oceanic island and coastal sites. The measurements and retrievals from the AERONET global network have addressed satellite and model validation needs very well, but there have been challenges in making comparisons to similar parameters from in situ surface and airborne measurements. Additionally, with improved spatial and temporal satellite remote sensing of aerosols, there is a need for higher spatial-resolution ground-based remote-sensing networks. An effort to address these needs resulted in a number of field campaign networks called Distributed Regional Aerosol Gridded Observation Networks (DRAGONs) that were designed to provide a database for in situ and remote-sensing comparison and analysis of local to mesoscale variability in aerosol properties. This paper describes the DRAGON deployments that will continue to contribute to the growing body of research related to meso- and microscale aerosol features and processes. The research presented in this special issue illustrates the diversity of topics that has resulted from the application of data from these networks
