How smart work environment applications can add strategic value

The way people work has changed and many corporate real estate (CRE) and facility managers (FM) are thinking about whether and how to implement smart-building applications in the work environments of their client. The data collected by these applications can be a valuable asset, however it is necessary to identify beforehand which type of data collection could provide which strategic value(s). Therefore, this study examined the expected strategic value of specific smart work environment applications for organizations from the perspective of CRE and FM professionals. A questionnaire was developed based on existing literature. In total, 122 CRE and FM experts participated and provided their perception of 20 different applications and 9 different strategic values. During follow-up expert interviews, the practical implications of the findings were discussed and translated into recommendations. The smart applications that are expected to decrease real estate costs mostly relate to the automatization of facility services. Employee satisfaction is particularly supported by smart applications related to personal preferences and personalization (e.g. temperature control, smart coffee machine). The smart applications that are expected to support productivity mostly concerned either features of the work environment (automatic printer and meeting room allocation), ways to eliminate negative conditions (noise cancelling), or support in finding colleagues elsewhere in the building. Although many studies have proven the effect of physical work environment characteristics on employees and/or on organizations, there is little insight into the effect of smart work environment applications on both. This paper has started to build theory on smart building applications. The findings in this paper are also relevant for CRE and facility managers and consultants as they provide insight in what their colleagues expect of different available smart work environment technology applications, to support their own decision making

Relationship of dietary monounsaturated fatty acids to blood pressure: the international study of macro/micronutrients and blood pressure

Objective: In short-term feeding trials, replacement of other macronutrients with monounsaturated fatty acid reduces blood pressure. However, observational studies have not clearly demonstrated a relationship between monounsaturated fatty acid intake and blood pressure. We report associations of monounsaturated fatty acid intake of individuals with blood pressure in a cross-sectional study. Methods: The International Study of Macro/Micronutrients and Blood Pressure is a cross-sectional epidemiologic study of 4,680 men and women ages 40-59 from 17 population samples in China, Japan, United Kingdom, and United States. Nutrient intake data were based on four in-depth multi-pass 24-hour dietary recalls/person and two timed 24-hour urine collections/person. Blood pressure was measured eight times at four visits. Results: Mean monounsaturated fatty acid intake ranged from 8.1 %kcal (China) to 12.2%kcal (United States). With sequential models to control for possible confounders (dietary, other), linear regression analyses showed significant inverse relationship of total monounsaturated fatty acid intake with diastolic blood pressure for all participants; for 2,238 “non-intervened” individuals, the relationship was stronger. Estimated diastolic blood pressure differences with 2-SD higher monounsaturated fatty acids (5.35 %kcal) were -0.82 mm Hg (P<0.05) for all participants and -1.70 mm Hg (P<0.01) for non-intervened individuals. Inverse associations of dietary total oleic acid (main monounsaturated) with blood pressure in non-intervened individuals were not significant, but those of oleic acid from vegetable sources were stronger and significant (P<0.05). Conclusions: Dietary monounsaturated fatty acid intake, especially oleic acid from vegetable sources, may contribute to prevention and control of adverse blood pressure levels in general populations. Condensed Abstract The associations of monounsaturated fatty acid intake of individuals with blood pressure was investigated in a cross-sectional epidemiologic study of 4,680 men and women ages 40-59 from 17 population samples in China, Japan, United Kingdom, and United States. Linear regression analyses showed significant inverse relationship of total monounsaturated fatty acid intake with diastolic blood pressure. Inverse associations of dietary total oleic acid from vegetable sources with blood pressure in non-intervened individuals were stronger and significant. Dietary monounsaturated fatty acid intake, especially oleic acid from vegetable sources, may contribute to prevention and control of adverse blood pressure levels in general populations

b-physics signals of the lightest CP-odd Higgs in the NMSSM at large tan beta

We investigate the low energy phenomenology of the lighter pseudoscalar $A_1^0$ in the NMSSM. The $A_1^0$ mass can naturally be small due to a global $U(1)_R$ symmetry of the Higgs potential, which is only broken by trilinear soft terms. The $A_1^0$ mass is further protected from renormalization group effects in the large $\tan \beta$ limit. We calculate the $b \to s A_1^0$ amplitude at leading order in $\tan \beta$ and work out the contributions to rare $K$, $B$ and radiative $\Upsilon$-decays and $B -\bar B$ mixing. We obtain constraints on the $A_1^0$ mass and couplings and show that masses down to ${\cal{O}}(10)$ MeV are allowed. The $b$-physics phenomenology of the NMSSM differs from the MSSM in the appearance of sizeable renormalization effects from neutral Higgses to the photon and gluon dipole operators and the breakdown of the MSSM correlation between the $B_s \to \mu^+ \mu^-$ branching ratio and $B_s - \bar B_s$ mixing. For $A_1^0$ masses above the tau threshold the $A_1^0$ can be searched for in $b \to s \tau^+ \tau^-$ processes with branching ratios \lsim 10^{-3}.Comment: 18 pages, 3 figures; references adde

Leptonic and Semileptonic Decays of Charm and Bottom Hadrons

We review the experimental measurements and theoretical descriptions of leptonic and semileptonic decays of particles containing a single heavy quark, either charm or bottom. Measurements of bottom semileptonic decays are used to determine the magnitudes of two fundamental parameters of the standard model, the Cabibbo-Kobayashi-Maskawa matrix elements $V_{cb}$ and $V_{ub}$. These parameters are connected with the physics of quark flavor and mass, and they have important implications for the breakdown of CP symmetry. To extract precise values of $|V_{cb}|$ and $|V_{ub}|$ from measurements, however, requires a good understanding of the decay dynamics. Measurements of both charm and bottom decay distributions provide information on the interactions governing these processes. The underlying weak transition in each case is relatively simple, but the strong interactions that bind the quarks into hadrons introduce complications. We also discuss new theoretical approaches, especially heavy-quark effective theory and lattice QCD, which are providing insights and predictions now being tested by experiment. An international effort at many laboratories will rapidly advance knowledge of this physics during the next decade.Comment: This review article will be published in Reviews of Modern Physics in the fall, 1995.

Meta-analysis of Genome-Wide Association Studies for Extraversion: Findings from the Genetics of Personality Consortium

Extraversion is a relatively stable and heritable personality trait associated with numerous psychosocial, lifestyle and health outcomes. Despite its substantial heritability, no genetic variants have been detected in previous genome-wide association (GWA) studies, which may be due to relatively small sample sizes of those studies. Here, we report on a large meta-analysis of GWA studies for extraversion in 63,030 subjects in 29 cohorts. Extraversion item data from multiple personality inventories were harmonized across inventories and cohorts. No genome-wide significant associations were found at the single nucleotide polymorphism (SNP) level but there was one significant hit at the gene level for a long non-coding RNA site (LOC101928162). Genome-wide complex trait analysis in two large cohorts showed that the additive variance explained by common SNPs was not significantly different from zero, but polygenic risk scores, weighted using linkage information, significantly predicted extraversion scores in an independent cohort. These results show that extraversion is a highly polygenic personality trait, with an architecture possibly different from other complex human traits, including other personality traits. Future studies are required to further determine which genetic variants, by what modes of gene action, constitute the heritable nature of extraversion

On the mechanisms governing gas penetration into a tokamak plasma during a massive gas injection

A new 1D radial fluid code, IMAGINE, is used to simulate the penetration of gas into a tokamak plasma during a massive gas injection (MGI). The main result is that the gas is in general strongly braked as it reaches the plasma, due to mechanisms related to charge exchange and (to a smaller extent) recombination. As a result, only a fraction of the gas penetrates into the plasma. Also, a shock wave is created in the gas which propagates away from the plasma, braking and compressing the incoming gas. Simulation results are quantitatively consistent, at least in terms of orders of magnitude, with experimental data for a D 2 MGI into a JET Ohmic plasma. Simulations of MGI into the background plasma surrounding a runaway electron beam show that if the background electron density is too high, the gas may not penetrate, suggesting a possible explanation for the recent results of Reux et al in JET (2015 Nucl. Fusion 55 093013)
