Two-dimensional materials represent a major frontier for research into exotic many-body quantum phenomena. In the extreme two-dimensional limit, electron-electron interaction often dominates over other electronic energy scales, leading to strongly correlated effects such as quantum spin liquid and unconventional *** dominance is conventionally attributed to the lack of electron screening in the third dimension. Here, we discover an intriguing metal to mott insulator transition in 1T-TaSe2that defies conventional wisdom. Specifically, we find that dimensionality crossover, instead of reduced screening, drives the transition in atomically thin 1T-TaSe2. A dispersive band crossing the Fermi level is found to be responsible for the bulk metallicity in the material. Reducing the dimensionality,however, effectively quenches the kinetic energy of these initially itinerant electrons, and drives the material into a mott insulating *** dimensionality-driven metal to mott insulator transition resolves the long-standing dichotomy between metallic bulk and insulating surface of 1T-TaSe2. Our work further reveals a new pathway for modulating two-dimensional materials that enables exploring strongly correlated systems across uncharted parameter space.

判例是彰显公平正义的载体。依托制定法传统,精准划分制定法与判例的边界,明确判例的法学性质及制度价值是成文法国家判例制度发挥其应有价值的前提。在与我国同样有着浓厚制定法传统的法国,司法机构行使最终法律解释权而作出的、起到生成法律规则作用的判决具有独立法源地位。法源地位的确立强化了法国判例的事实约束力,使其能在尊重司法权与立法权分离原则的基础上,持续发挥解释制定法、推动制定法发展的作用。同时,也为“准宪法”条款等制定法及合宪性审查对判例进行约束提供了正当性依据。法国法学界论述判例法源地位的路径、判例制度的构建及相关约束措施的设置,为我国指导性案例制度的发展提供了可供参考的样本。

Bayesian meta-analysis of regional biomass factors for Quercus mongolica forests in South korea

引用

Journal of Forestry Research 2015年第4期26卷 875-885页

作者： Tzeng Yih Lam Xiaodong Li Rae Hyun kim kyeong Hak Lee Yeong mo son Division of Forest Management Department of Forest and Climate Change Korea Forest Research Institute57 Hoegiro Dongdaemun-gu Seoul 130-712 South Korea School of Forestry and Resource Conservation National Taiwan University

Indirect approaches to estimation of biomass factors are often applied to measure carbon flux in the forestry sector. An assumption underlying a country-level carbon stock estimate is the representativeness of these factors. Although intensive studies have been conducted to quantify biomass factors, each study typically covers a limited geographic area. The goal of this study was to employ a meta-analysis approach to develop regional bio- mass factors for Quercus mongolica forests in South korea. The biomass factors of interest were biomass conversion and expansion factor （BCEF）, biomass expansion factor （BEF） and root-to-shoot ratio （RSR）. Our objectives were to select probability density functions （PDFs） that best fitted the three biomass factors and to quantify their means and uncertainties. A total of 12 scientific publications were selected as data sources based on a set of criteria. Fromthese publications we chose 52 study sites spread out across South korea. The statistical model for the meta- analysis was a multilevel model with publication （data source） as the nesting factor specified under the Bayesian framework. Gamma, Log-normal and Weibull PDFs were evaluated. The Log-normal PDF yielded the best quanti- tative and qualitative fit for the three biomass factors. However, a poor fit of the PDF to the long right tail of observed BEF and RSR distributions was apparent. The median posterior estimates for means and 95 % credible intervals for BCEF, BEF and RSR across all 12 publica- tions were 1.016 （0.800-1.299）, 1.414 （1.304-1.560） and 0.260 （0.200-0.335）, respectively. The Log-normal PDF proved useful for estimating carbon stock of Q. mongolica forests on a regional scale and for uncertainty analysis based on monte Carlo simulation.

土壤盐渍化是世界性生态环境问题,是阻碍作物生长并致使农业生产损失的潜在非生物胁迫因子之一。利用植物根际促生菌促进植物生长,提高植物耐盐性,缓解植物所受的非生物胁迫被视为1种新兴有效可行方法。本研究以实验室前期于南海岛礁根际土壤中分离到的1株特基拉芽孢杆菌(Bacillus tequilensis)Bt-RS为研究对象,利用功能培养基对其耐盐特性和耐盐促生性状进行定性定量分析,并进一步通过土壤盆栽实验评价该菌株在盐胁迫环境下对香蕉幼苗生长的影响。研究结果显示:Bt-RS菌株能够在NaCl含量为0~10%的条件下生长,能耐受多种类型盐分,具有产1-氨基环丙烷-1-羧酸(1-aminocyclopropane-1-carboxylate,ACC)脱氨酶能力;在1%~5%的NaCl浓度下能够分泌植物生长素吲哚-3-乙酸(indole-3-acetic acid,IAA),最大产量值为6.4mg/L。盆栽实验结果显示:在正常条件下,接种菌株Bt-RS的香蕉幼苗相比未接种菌株其株高、叶面积、地上部分鲜重、地下部分鲜重、地上部分干重、地下部分干重分别提高40.30%、93.00%、102.38%、81.08%、65.82%、50.50%;在200mmol/L盐胁迫环境下,接种菌株Bt-RS的香蕉幼苗与对照组相比在株高、叶面积、地上部分鲜重、地下部分鲜重、地上部分干重、地下部分干重方面分别提高20.55%、65.01%、98.14%、144.93%、87.85%、54.01%;在正常条件与盐胁迫下接种菌株均能显著提高香蕉幼苗的株高、叶面积以及生物量(P<0.05),盐胁迫环境下的实验组与正常条件下的对照组相比在株高和叶面积上均无显著差异,因此通过施用菌株Bt-RS能够有效缓解NaCl对香蕉幼苗的胁迫,促进香蕉幼苗的生长。综上结果表明,特基拉芽孢杆菌Bt-RS具有较强的耐盐性以及产IAA和ACC能力,能够促进香蕉幼苗生长并在盐胁迫环境下显著提高植物耐盐性,可为开发与利用盐渍土提供菌株资源。
