We proposed a protocol of.measuring the duration of.ultra-short single-photon pulse with two-photon *** pulse duration can be obtained f.om the width of.the visibility of.two-photon Hong-ou-Mandel interf.rence or the indistinguishability of.the two ***,the shape of.a single-photon pulse can be measured with ultra-short single-photon pulses through the two-photon interf.rence.

Crouzon syndrome is the result of.a gain-of.f.nction point mutation in f.f.2. Mimicking the human mutation, a mouse model of.Crouzon syndrome(f.f.2342Y) recapitulates patient def.rmities, including f.iled tracheal cartilage segmentation, resulting in a cartilaginous sleeve in the homozygous mutants. We f.und that the f.f.2C342Y/C^342Y mutants exhibited an increase in chondrocytes prior to segmentation. This increase is due at least in part to over prolif.ration. Genetic ablation of.chondrocytes in the mutant led to restoration of.segmentation in the lateral but not central portion of.the trachea. These results suggest that in the f.f.2C342Y/C342Y mutants, increased cartilage cell prolif.ration precedes and contributes to the disruption of.cartilage segmentation in the developing trachea.

Tars and alkali ashes f.om biomass gasif.cation processes currently constitute one of.the major problems in biomass valorisation, generating clogging of.f.lters and issues related with the purity of.syngas production. To date, these waste residues f.nd no usef.l applications and they are generally disposed upon generation in the gasif.cation process. A detailed analysis of.these residues pointed out the presence of.high quantities of.ca （〉30 wt%）. TG experiments indicated that a treatment under air at moderate temperatures （400-800 ~C） decomposed the majority of.carbon species, while XRD indicated the presence of.a crystalline cao phase. cao enriched valorized materials turned out to be good heterogeneous catalysts f.r biodiesel production f.om vegetable oils, providing moderate to good activities （50%-70% af.er 12 h） to f.tty acid methyl esters in the transesterif.cation of.sunf.ower oil with methanol.

Gut microbiota is a community of.microorganisms that reside in the gastrointestinaltract. An increasing number of.studies has demonstrated that the gutliveraxis plays a critical role in liver homeostasis. Dysbiosis of.gut microbiota cancause liver diseases, including nonalcoholic f.tty liver disease and alcoholic liverdisease. Preclinical and clinical investigations have substantiated that themetabolites and other molecules derived f.om gut microbiota and diet interactionf.nction as mediators to cause liver f.brosis, cirrhosis, and f.nal cancer. This ef.ecthas been demonstrated to be associated with dysregulation of.intrahepaticimmunity and liver metabolism. Targeting these f.ndings have led to thedevelopment of.novel preventive and therapeutic strategies. Here, we review thecellular and molecular mechanisms underlying gut microbiota-mediated impacton liver disease. We also summarize the advancement of.gut microbiota-basedtherapeutic strategies in the control of.liver diseases.

In a social network analysis the output provided includes many measures and metrics. f.r each of.these measures and metric, the output provides the ability to obtain a rank ordering of.the nodes in terms of.these measures. We might use this inf.rmation in decision making concerning disrupting or deceiving a given network. All is f.ne when all the measures indicate the same node as the key or inf.uential node. What happens when the measures indicate dif.erent key nodes？ our goal in this paper is to explore two methodologies to identif. the key players or nodes in a given network. We apply ToPSIS to analyze these outputs to f.nd the most inf.uential nodes as a f.nction of.the decision makers＇ inputs as a process to consider both subjective and objectives inputs through pairwise comparison matrices. We illustrate our results using two common networks f.om the literature： the Kite network and the Inf.rmation f.ow network f.om Knoke and Wood. We discuss some basic sensitivity analysis can may be applied to the methods. We f.nd the use of.ToPSIS as a f.exible method to weight the criterion based upon the decision makers＇ inputs or the topology of.the network.

磷灰石中挥发分的类质同象替换可以反映其结晶时岩浆体系的成分特点。采用扫描电镜、能谱、电子探针、X射线单晶晶胞参数测定和红外、拉曼光谱,对维苏威和武尔卡诺火山碎屑物中磷灰石进行了初步研究,发现其ca、P位置上不出现替换,主要替换形成于通道位置上。武尔卡诺磷灰石低硫富Cl,晶胞参数c/a值很小,在低压高温下形成;而维苏威磷灰石含硫稍多,通道离子主要由oH-f.成,形成于压力较大、温度较低的环境,Cl趋向于在早期喷发物中富集,而f.趋向于在晚期喷发物中富集。
