Applied m.them.tics(A Journal of Chinese Universities) 2016年第4期31卷 409-424页

作者： Yolanda m. gomez Ignacio Vidal departam.nto de m.tem.ticas facultad de ciencias universidad de católica del norte Antofagasta Chile instituto de m.tem.tica y física universidad de talca Chile

In this paper we introduce an extension of the half-norm.l distribution in order to m.del a great variety of non-negative data. Its hazard rate function can be decreasing or increasing, depending on its param.ters. Som. properties of this new distribution are presented. For exam.le, we give a general expression for the m.m.nts and a stochastic representation. Also, the cum.lative distribution function, the hazard rate function, the survival function and the quantile function can be easily evaluated. m.xim.m.likelihood estim.tors can be com.uted by using num.rical procedures. Finally, a real-life dataset has been presented to illustrate its applicability.

Influence of m.tal support in-plane sym.etry on the corrugation of hexagonal boron nitride and graphene m.nolayers

引用

Nano Research 2018年第9期11卷 4643-4653页

作者： Antonio d. m.rtinez-Galera Jose m. gomez-Rodriguez Departam.nto de Fisica de la m.tefia Condensada Universidad Autonoma de Madrid Madrid E-28049 Spain Condensed m.tter Physics Center (IFIm.C) UniversidadAutdnoma de Madrid Madrid E-28049 Spain Instituto Nicolds Cabrera Universidad Autonoma de Madrid Madrid E-28049 Spain

Predicting the properties of two-dim.nsional （2D） m.terials as graphene and hexagonal boron nitride （h-BN） m.nolayers after their growth on any given substrate is a m.jor challenge. While the influence of the electron configuration of the atom. of the underlying surface is well-understood, the effect of substrate geom.try still rem.ins unclear. The structural properties of h-BN m.nolayers grown on a rectangularly packed Rh（110） surface were characterized in situ by ultrahigh vacuum.scanning tunneling m.croscopy and were com.ared to those that this m.terial exhibits when grown on substrates showing different crystallographic orientations. Although the h-BN m.nolayer grown on Rh（110） was dom.nated by a unique quasiunidim.nsional m.ir6 pattern, suggesting considerable interface interaction, the m.ir6 corrugation was unexpectedly sm.ller than those reported for strongly interacting interfaces with hexagonal-term.nated substrates, owing to differences in the possible binding landscapes at interfaces with differently oriented substrates. m.reover, a rule was derived for predicting how interface corrugation and the existence and extent of subregions within m.ir6 supercells containing favorable sites for orbital m.xing between h-BN m.nolayers and their supports depend on substrate sym.etry. These general sym.etry considerations can be applied to num.rous 2D m.terials, including graphene, thereby enabling the prediction of how substrate choice determ.nes the properties of these m.terials. Furtherm.re, they could also provide new routes for tuning 2D m.terial properties and for developing nanotem.lates showing different geom.tries for Krowing adsorbate superlattices.

Recently, Clancy [SIR epidem.c m.dels with general infectious period distribution, Statist. Prob. Left. 85 （2014） 1-5] has shown how SIR epidem.cs in which individuals＇ infection periods are not necessarily exponentially distributed m.y be m.deled in term. of a piecewise-determ.nistic m.rkov process （PDm.）. In this paper, we present a m.re detailed description of the underlying PDm., from.which we analyze the population transm.ssion num.er and the infection probability of a certain susceptible individual.

Alternative splicing enhances transcriptom. com.lexity in desiccating seeds

Before being dispersed in the environm.nt, m.ture seeds need to be dehydrated. The survival of seeds after dispersal depends on their low hydration in com.ination with high desiccation tolerance. These characteristics are estab- lished during seed m.turation. Som. key seed m.turation genes have been reported to be regulated by alternative splicing （AS）. However, so far AS was described only for single genes and a com.rehensive analysis of AS during seed m.turation has been lacking. We investigated gene expression and AS during Arabidopsis thaliana seed developm.nt at a global level, before and after desiccation. Bioinform.tics tools were developed to identify differentially spliced regions within genes. Our data suggest the im.ortance and shows the peculiar features of AS during seed desiccation. We identified AS in 347o of genes that are expressed at both tim.points before and after desiccation. m.st of these AS transcript variants had not been found before in other tissues. Am.ng the AS genes som. seed m.ster regulators could be found. Interestingly, 6% of all expressed transcripts were not transcriptionally regulated during desiccation, but only m.dified by AS. We propose that AS should be m.re routinely taken into account in the analysis of transcriptom.c data to prevent overlooking potentially im.ortant regulators.

Copper-decorated carbon nanotubes(CNTs) have im.ortant applications as precursors for ultraconductive copper wires. Tenorite-decorated CNTs(CuO-CNTs) are ideal candidates and are currently developed using laborious processes. For this reason, we have developed a facile and scalable m.thod for the synthesis of CuO-CNTs from.copper acetate. It was found that the optim.l loading of copper acetate onto the CNTs was 23.1 wt% and that three 1-m.nute m.crowave treatm.nts were sufficient for the decom.osition of copper acetate to copper oxide. The loading of copper oxide onto the nanotubes was confirm.d using X-ray photoelectron spectroscopy, energy-dispersive X-ray spectroscopy and therm.gravim.tric analysis. The m.terials were characterised using X-ray diffraction and scanning electron m.croscopy.

The present contributions deal with the developm.nt and im.lem.ntation of the direct and adjoint incom.ressible Navie-Stokes equations in a m.trix-free tim.-stepping context m.king use of the open-source OpenFOAm. （open source field operation and m.nipulation） C ＋＋ tool- box. It is shown that a few m.nor m.difications in the source code can enable these m.lti-purpose com.utational fluid dynam.cs （CFD） solvers to carry out global instability analysis of three- dim.nsional flows of engineering interest, exploiting all additional capabilities of such codes. The strength of this m.thodology is dem.nstrated through the analysis of an interesting selection of ooen and wall-bounded flows.

The effect of rippling on the m.chanical properties of graphene

Nano m.terials Science 2022年第1期4卷 18-26页

Graphene is the stiffest m.terial known so far but, due to its one-atom.thickness, it is also very ***, free-standing graphene exhibit ripples that has m.jor effects on its elastic properties. Here we will sum.arize three experim.nts where the influence of rippling is essential to address the results. Firstly, we observed that atom.c vacancies lessen the negative therm.l expansion coefficient(TEC) of free-standing *** also observed an increase of the Young's m.dulus with global applied strain and with the introduction of sm.ll density defects that we attributed to the decrease of rippling. Here, we will focus on a surprising feature observed in the data: the experim.nts consistently indicate that only the rippling with wavelengths between 5 and 10 nm.influences the m.chanics of graphene. The rippling responsible of the negative TEC and anom.lous elasticity is thought to be dynam.c, i.e. flexural phonons. However, flexural phonons with these wavelengths should have m.nor effects on the m.chanics of graphene, therefore other m.chanism. m.st be considered to address our observations. We propose static ripples as one of the key elem.nts to correctly understand the therm.m.chanics of graphene and suggest that rippling arises naturally due to a com.etition of sym.etry breaking and anharm.nic fluctuations.

Haplotype phasing after joint estim.tion of recom.ination and linkage disequilibrium.in breeding populations

Journal of Anim.l Science and Biotechnology 2014年第1期5卷 38-52页

A novel m.thod for haplotype phasing in fam.lies after joint estim.tion of recom.ination fraction and linkage disequilibrium.is developed. Results from.m.nte Carlo com.uter sim.lations show that the newly developed E.m. algorithm.is accurate if true recom.ination fraction is 0 even for single fam.lies of relatively sm.ll sizes. Estim.tes of recom.ination fraction and linkage disequilibrium.were 0.00 （SD 0.00） and 0.19 （SD 0.03） for sim.lated recom.ination fraction and linkage disequilibrium.of 0.00 and 0.20, respectively. A genom. fragm.ntation phasing strategy was developed and used for phasing haplotypes in a sire and 36 progeny using the 50 k Illum.na BeadChip by： a） estim.tion of the recom.ination fraction and LD in consecutive SNPs using fam.ly inform.tion, b） linkage analyses between fragm.nts, c） phasing of haplotypes in parents and progeny and in following generations. Hom.zygous SNPs in progeny allowed determ.nation of paternal fragm.nt inheritance, and deduction of SNP sequence inform.tion of haplotypes from.dam.. The strategy also allowed detection of genotyping errors. A total of 613 recom.ination events were detected after linkage analysis was carried out between fragm.nts. Hot and cold spots were identified at the individual （sire level）. SNPs for which the sire and calf were heterozygotes becam. inform.tive （over 90%） after the phasing of haplotypes. Average of regions of identity between half-sibs when com.aring its m.ternal inherited haplotypes （with at least 20 SNP） in com.on was 0.11 with a m.xim.m.of 0.29 and a m.nim.m.of 0.05. A m.nte-Carlo sim.lation of BTA1 with the sam. linkage disequilibrium.structure and genetic linkage as the cattle fam.ly yielded a 99.98 and 99.94% of correct phases for inform.tive SNPs in sire and calves, respectively.
