Surface theorem for the Chern-Simons axion coupling

The Chern-Simons axion coupling of a bulk insulator is only defined modulo a quantum of e^2/h. The quantized part of the coupling is uniquely defined for a bounded insulating sample, but it depends on the specific surface termination. Working in a slab geometry and representing the valence bands in terms of hybrid Wannier functions, we show how to determine that quantized part from the excess Chern number of the hybrid Wannier sheets located near the surface of the slab. The procedure is illustrated for a tight-binding model consisting of coupled quantum anomalous Hall layers. By slowly modulating the model parameters, it is possible to transfer one unit of Chern number from the bottom to the top surface over the course of a cyclic evolution of the bulk Hamiltonian. When the evolution of the surface Hamiltonian is also cyclic, the Chern pumping is obstructed by chiral touchings between valence and conduction surface bands.Comment: 15 page

Double Bottom Line Project Report: Assessing Social Impact in Double Bottom Line Ventures

This tool expresses costs and social impacts of an investment in monetary terms. Quantification is achieved according to one or more of three measures: NPV (the aggregate value of all costs, revenues and social impacts discounted), benefit-cost ratio (the discounted value of revenues and positive impacts divided by discounted value of costs and negative impacts) and internal rate of return (the net value of revenues plus impacts expressed as an annual percentage return on the total costs of the investment)

Relevance differently affects the truth, acceptability, and probability evaluations of “and”, “but”, “therefore”, and “if–then”

In this study we investigate the influence of reason-relation readings of indicative conditionals and ‘and’/‘but’/‘therefore’ sentences on various cognitive assessments. According to the Frege-Grice tradition, a dissociation is expected. Specifically, differences in the reason-relation reading of these sentences should affect participants’ evaluations of their acceptability but not of their truth value. In two experiments we tested this assumption by introducing a relevance manipulation into the truth-table task as well as in other tasks assessing the participants’ acceptability and probability evaluations. Across the two experiments a strong dissociation was found. The reason-relation reading of all four sentences strongly affected their probability and acceptability evaluations, but hardly affected their respective truth evaluations. Implications of this result for recent work on indicative conditionals are discussed

Conditionals, Individual Variation, and the Scorekeeping Task

In this manuscript we study individual variation in the interpretation of conditionals by establishing individual profiles of the participants based on their behavioral responses and reflective attitudes. To investigate the participants’ reflective attitudes we introduce a new experimental paradigm called the Scorekeeping Task, and a Bayesian mixture model tailored to analyze the data. The goal is thereby to identify the participants who follow the Suppositional Theory of conditionals and Inferentialism and to investigate their performance on the uncertain and-to-if inference task

Agglomeration mechanism during the preparation of nickel(0) and iron(0) zeolites

Magnetization measurements have been used to study the reduction process of Ni - zeolites and the thermal decomposition of iron pentacarbonyl adsorbed on NaY zeolites . The Ni(0) particle size distribution in H2»reduced NiNaA, Ni NaX, Ni NaY and NiNaM is bidisperse. The amount and the volume of particles exceeding the cage dimensions increases in the sequence Μ,Υ,Χ,Α zeolites. Particle fusion is found to be the rate determining step. With decomposition of Fe(C0)5/NaY adducts, up to 97 wt.% of the iron particles produced are smaller than 1.3 nm. Fluidized sample bed, inert gas atmosphere and fast heating up to 440 Κ are essential to reach mononodal dispersion

Teaching Advanced SQL Skills: Text Bulk Loading

Studies show that advanced database skills are important for students to be prepared for today\u27s highly competitive job market. A common task for database administrators is to insert large amounts of data into a database. This paper illustrates how an up-to-date advanced database topic, namely bulk insert, can be incorporated into a database class. It gives detailed examples on how to import different file types and discusses associated issues

The Business Intelligence Group: Towards Collaborative Research In A Management Information Systems Curriculum

This paper introduces an extension of an approach referred to as the Research Group model, an award winning pedagogical methodology based on the premise that when undergraduate students engage in academic research in close consultation with their professors that their marketable skills are greatly enhanced and that the institutions involved benefit greatly as well. The history of the Research Group concept is detailed, the incentive structure that facilitates faculty buy in is explained and the extension to the general model that defines the Business Intelligence (BI) Group is described. The paper outlines several exemplar projects that have resulted from the approach

Prevalence and predictors of postdischarge antibiotic use following mastectomy

OBJECTIVESurvey results suggest that prolonged administration of prophylactic antibiotics is common after mastectomy with reconstruction. We determined utilization, predictors, and outcomes of postdischarge prophylactic antibiotics after mastectomy with or without immediate breast reconstruction.DESIGNRetrospective cohort.PATIENTSCommercially insured women aged 18–64 years coded for mastectomy from January 2004 to December 2011 were included in the study. Women with a preexisting wound complication or septicemia were excluded.METHODSPredictors of prophylactic antibiotics within 5 days after discharge were identified in women with 1 year of prior insurance enrollment; relative risks (RR) were calculated using generalized estimating equations.RESULTSOverall, 12,501 mastectomy procedures were identified; immediate reconstruction was performed in 7,912 of these procedures (63.3%). Postdischarge prophylactic antibiotics were used in 4,439 procedures (56.1%) with immediate reconstruction and 1,053 procedures (22.9%) without immediate reconstruction (P&lt;.001). The antibiotics most commonly prescribed were cephalosporins (75.1%) and fluoroquinolones (11.1%). Independent predictors of postdischarge antibiotics were implant reconstruction (RR, 2.41; 95% confidence interval [CI], 2.23–2.60), autologous reconstruction (RR, 2.17; 95% CI, 1.93–2.45), autologous reconstruction plus implant (RR, 2.11; 95% CI, 1.92–2.31), hypertension (RR, 1.05; 95% CI, 1.00–1.10), tobacco use (RR, 1.07; 95% CI, 1.01–1.14), surgery at an academic hospital (RR, 1.14; 95% CI, 1.07–1.21), and receipt of home health care (RR, 1.11; 95% CI, 1.04–1.18). Postdischarge prophylactic antibiotics were not associated with SSI after mastectomy with or without immediate reconstruction (bothP&gt;.05).CONCLUSIONSProphylactic postdischarge antibiotics are commonly prescribed after mastectomy; immediate reconstruction is the strongest predictor. Stewardship efforts in this population to limit continuation of prophylactic antibiotics after discharge are needed to limit antimicrobial resistance.Infect Control Hosp Epidemiol2017;38:1048–1054</jats:sec
