The outbreak of coronavirus disease 2019 (COVID-19) caused by the severe acute respiratorysyndrome coronavirus 2 has rapidly spread globally. Cancer patients are at a higher risk ofbeing infected with the coronavirus and are more likely to develop severe complications, ascompared to the general population. The increasing spread of COVID-19 presents challengesfor the clinical care of patients with gynecological malignancies. Concerted efforts should beput into managing gynecological malignancies in an orderly manner by strictly implementingthe measures that are specifically developed for controlling the spread of COVID-19. We havedrafted Recommendations on Management of Gynecological Malignancies during the COVID-19 Pandemicbased on our experience on controlling COVID-19 pandemic in China. We recommendthat patients with gynecological malignancies should be managed in hierarchical andindividualized manners in combination with local conditions related to COVID-19. Medicalcare decision should be balanced between controlling COVID-19 pandemic spread and timelydiagnosis and treatment for gynecologic oncology patients.

Wang, Wang, Yu-Qing,Zhou, Zhou, Ben-Lian 한국재료학회 1995 Fabrication and Characterization of Advanced Mater Vol.1 No.2
The behavior of SiC coating in carbon fiber reinforced aluminum, metal coatings, Ni, Fe in carbon fiber reinforced copper and alumina coated $K_2O{\cdot}6TiO_2$ whisker reinforced aluminum composites were investigated, respectively, by modern devices, like TEM, SEM etc. with the goal of controlling the interfacial interaction and wettability of reinforcement, like carbon fibers, $K_2O{\cdot}6TiO_2$ whiskers with matrices. SiC coating produced by a polycarbosilane solution process improved effectively the strength because it successfully resisted the oxidation of carbon fibers themselves and the harmful reaction between carbon fibers and molten aluminum during fabrication process and heating process of the composites. The metal coating, Fe and Ni by electrical plating, strengthened the bonding of carbon fibers with copper, by changing the bonding state of the interface from mechanical one to partly chemical one. Therefore the strengths of composites were improved obviously. The aluminal coating on $K_2O{\cdot}6TiO_2$ alos controlled the diffusion of K element from whiskers into aluminum matrix and reaction with aluminum and led the optimaization of interfacial bonding between the whiskers and aluminum, so that the properties of the composites reached a higher level.

<P><B>Abstract</B></P> <P>Due to the relatively slow, diffusion-controlled faradaic reaction mechanisms of conventional LiFePO<SUB>4</SUB> (LFP) materials, which is hard to deliver satisfied capacity for high rate applications. In this work, ultrafine LFP quantum dots (LFP-QDs) co-modified by two types of carbonaceous materials - amorphous carbon and graphitized conductive carbon (graphene) have been successfully synthesized through a novel microreactor strategy. Because of the very limited area constructed by the dual-carbon microreactor for the growth of LFP crystal, it's demension was furthest suppressed to a very small level (~ 6.5nm). Such a designed nano-composite possesses a large specific surface area for charge adsorption and abundant active sites for faradaic reactions, as well as ideal kinetic features for both electron and ion transport, and thus exhibits ultra-fast, surface-reaction-controlled lithium storage behavior, mimicking the pseudocapacitive mechanisms for supercapacitor materials, in terms of extraordinary rate capability (78mAhg<SUP>−1</SUP> at 200C) and remarkable cycling stability (~ 99% over 1000 cycles at 20C). On the other side, due to the quasi-2D structure of the synthesized LFP-QDs composite, which can be used as the basic unit to further fabricate free-standing film, aerogel and fiber electrode without the addition of binder and conductive agent for different practical applications.

A novel pulse fitting analysis (PFA) method is presented for the acquisition of nuclear spectra. Thecharging process of the feedback capacitor in the resistive feedback charge-sensitive preamplifier isequivalent to the impulsive pulse, and its impulse response function (IRF) can be obtained by non-linearfitting of the falling edge of the nuclear pulse. The integral of the IRF excluding the baseline representsthe energy deposition of the particles in the detector. In addition, since the non-linear fitting process inPFA method is difficult to achieve in the conventional architecture of spectroscopy system, a new multichannel analyzer (MCA) based on Zynq SoC is proposed, which transmits all the data of nuclear pulsesfrom the programmable logic (PL) to the processing system (PS) by high-speed AXI-Stream in order toimplement PFA method with precision. The linearity of new MCA has been tested. The spectrum of 137Cswas obtained using LaBr3(Ce) scintillator detector, and was compared with commercial MCA by ORTEC. The results of tests indicate that the MCA based on PFA method has the same performance as thecommercial MCA based on pulse height analysis (PHA) method and excellent linearity for g-rays withdifferent energies, which infers that PFA method is an effective and promising method for the acquisitionof spectra. Furthermore, it provides a new solution for nuclear pulse processing algorithms involvingregression and iterative processes

Statins are a class of lipid-lowering drugs commonly used in the prevention of cardiovascular diseases. However, statin therapy presents many limitations, which have led to an increased interest in non-drug therapies, such as probiotics, to improve blood cholesterol levels. Indeed, probiotic strains such as Lactobacillus acidophilus have been found to improve blood lipid profiles, especially in reducing total cholesterol and LDL-C levels. In this study, we established a high-cholesterol rat model and studied the effect of Lactobacillus acidophilus administration alone or in combination with rosuvastatin. We were able to show that Lactobacillus exerts a cholesterol-lowering effect. Additionally, we observed that when administered together, rosuvastin and Lactobacillus exert a combined cholesterol-lowering effect. Altogether, our data advocate for the possibility of establishing probiotics as non-drug supplements for the treatment of hypercholesterolemia.
Job Search Activity of Unemployed Married Men and Women in Canada
Yaping Zhou(Yaping Zhou),Yixuan Wang(Yixuan Wang) 한국캐나다학회 2011 Asia-Pacific Journal of Canadian Studies (APJCS) Vol.17 No.1
Cyclical bust and boom and the resulting economic restructuring result in some workers being forced out of work. Based on the controversy over the presence or absence of gender differences in coping responses to unemployment that differ in unequal expectations of sex roles and sexual division of labor among the unemployed married individuals, this paper, using the 2008 Labor Force Survey conducted by Statistics Canada, explores whether there are gender-based differences in job seeking, one of the most important strategies for coping responses to unemployment. The finding shows that women value their employment as much as men and make similar efforts to re-enter the labor market when unemployed.
RUNES II : A Distributed Rule Engine Based on Rete Network in Cloud Computing
Rui Zhou,Guowei Wang,Jinghan Wang,Jing Li 보안공학연구지원센터 2014 International Journal of Grid and Distributed Comp Vol.7 No.6
In recent years, cloud computing has drawn more and more attention. Increasingly amount of systems and applications have been constructed in cloud environments, yet few researches of rule engine has been done. Rule engine technologies have been widely used in the development of enterprise information systems. These rule-based systems may encounter the problem of low performance, when a large amount of fact data are matched with these rules. Deploying rule engines in cloud environments can increase the capability and efficiency of these systems. In this paper, we propose an approach to implement rule engine based on a message-passing concurrency model in cloud computing. The approach can be extended conveniently and it can deal with extensive rules and facts efficiently. To improve the performance of the rule engine, an algorithm of allocation is proposed. A resource cost model is explored to make high efficient use of resources in cloud. In addition, we implement the rule engine system RUNES II in cloud platform and conduct experiments to show its performance.

Differentiation from proplastids into chloroplasts isa light- and energy-dependent process. How this process isregulated is still poorly understood at the molecular level. We herein report a new putative plastidial adenine nucleotidetransporter, BRITTLE1-3 (referred to as OsBT1-3), encoded bythe rice (Oryza sativa) White Stripe Leaf 2 (WSL2) gene. Loss of OsBT1-3 function results in defective chloroplastbiogenesis, severely reduced photosynthetic efficiency, andfinally a white stripe leaf phenotype in the first four leaves. The expression levels of genes related to chlorophyllbiosynthesis and photosynthesis are drastically reduced,accompanied with over accumulation of reactive oxygenspecies (ROS) in the wsl2 mutant. OsBT1-3 is targeted tothe chloroplasts and it expresses in almost all tissues inplants, especially in young leaves. OsBT1-3 consists of 419amino acids and exhibits features of all mitochondrialcarrier proteins, including a typical transmembrane-spanningdomain and a highly conserved sequence motif designatedas the ‘mitochondrial energy transfer signatures’. Phylogeneticanalysis shows that OsBT1-3 is a putative plastidialadenine nucleotide transporter and is most closely relatedto ZmBT1-2. Together, these observations suggest that thenew putative adenine nucleotide transporter, OsBT1-3,plays an essential role in regulating chloroplast biogenesisand maintenance of ROS homeostasis during rice seedlingde-etiolation.
