IMU-Based Indoor Localization for Construction Applications

Localization and tracking of resources on construction jobsites is an emerging area where the location of materials, labour, and equipment is used to estimate productivity, measure project's progress and/or enhance jobsite safety. GPS has been widely used for outdoor tracking of construction operations. However, GPS is not suitable for indoor applications due to the lack of signal coverage; particularly inside tunnels or buildings. Several indoor localization research had been attempted, however such developments rely heavily on extensive external communication network infrastructures. These developments also are susceptible to electromagnetic interference in noisy construction jobsites. This paper presents indoor localization system using a microcontroller equipped with an inertial measurement unit (IMU). The IMU contains a cluster of sensors: accelerometer, gyroscope and magnetometer. The microcontroller uses a direct cosine matrix algorithm to fuse sensors data and calculate non-gravitational acceleration using ninedegrees-of-freedom motion equations. Current position is calculated based on measured acceleration and heading, while accounting for growing error in speed estimation utilizing jerk integration algorithm. Experimental results are presented to illustrate the relative effectiveness of the developed system, which is able to operate independently of any external aids and visibility conditions.
Multi-User Oblivious RAM Secure Against Malicious Servers

It has been an open question whether Oblivious RAM stored on a malicious server can be securely shared among multiple users. ORAMs are stateful, and users need to exchange updated state to maintain security. This is a challenge, as the motivation for using ORAM is that the users may not have a way to directly communicate. A malicious server can potentially tamper with state information and thus break security. We answer the question of multi-user ORAM on malicious servers affirmatively by providing several new, efficient multi-user ORAM constructions. We first show how to make the original square-root solution by Goldreich and the hierarchical one by Goldreich and Ostrovsky multi-user secure. We accomplish this by separating the critical parts of the access, which depend on the state of the ORAM, from the non-critical parts that can be safely executed in any state. Our second and main contribution is a multi-user variant of Path ORAM. To enable secure meta-data update during evictions, we employ our first result, small multi-user secure classical ORAMs, as a building block. Depending on the block size, the overhead of our multi-user secure construction reaches a low O(logn) communication complexity per user, similar to state-of-the-art single-user ORAMs.
ocial and geographic contexts of adolescent substance use : The moderating ffects of age and gender

This study investigates whether age and gender moderate the effects of social network and neighborgocentric social network ocial disorganization ontextual effects eighborhood effects ctivity space oderation hood contexts on adolescent substance use using a spatially embedded, egocentric social network data set comprised of 254 urban adolescents. Results indicate that substance use is enhanced by being older and male, as well as the presence of neighborhood concentrated disadvantage and interaction with substance using peers at adolescents’ perceived risky places. Older adolescents are more strongly influenced by social and neighborhood contexts than younger adolescents, where ages 14–16 appear to be a key transition age for the emergence of contextual effects on substance use.
On the Optimality of the Backward Greedy Algorithm for the Subset Selection Problem

The following linear inverse problem is considered: Given a full column rank m × n data matrix A, and a length m observation vector b, find the best least-squares solution to A x = b with at most r < n nonzero components. The backward greedy algorithm computes a sparse solution to A x = b by removing greedily columns from A until r columns are left. A simple implementation based on a QR downdating scheme using Givens rotations is described. The backward greedy algorithm is shown to be optimal for the subset selection problem in the sense that it selects the "correct" subset of columns from A if the perturbation of the data vector b is small enough. The results generalize to any other norm of the residual.
SETD6 controls the expression of estrogen-responsive genes and proliferation of breast carcinoma cells

The lysine methyltransferase SETD6 modifies the histone variant H2AZ, a key component of nuclear receptor-dependent transcription. Herein, we report the identification of several factors that associate with SETD6 and are implicated in nuclear hormone receptor signaling. Specifically, SETD6 associates with the estrogen receptor α (ERα), histone deacetylase HDAC1, metastasis protein MTA2, and the transcriptional co-activator TRRAP. Luciferase reporter assays identify SETD6 as a transcriptional repressor, in agreement with its association with HDAC1 and MTA2. However, SETD6 behaves as a co-activator of several estrogen-responsive genes, such as PGR and TFF1. Consistent with these results, silencing of SETD6 in several breast carcinoma cell lines induced cellular proliferation defects accompanied by enhanced expression of the cell cycle inhibitor CDKN1A and induction of apoptosis. Herein, we have identified several chromatin proteins that associate with SETD6 and described SETD6 as an essential factor for nuclear receptor signaling and cellular proliferation.
Digital proportional-resonant (PR) control with anti-windup applied to a voltage-source inverter

Integral anti-windup is crucial for controlling converters subjected to constrains by the dc-link voltage. However, little literature is available about anti-windup if PR-controllers are applied. This paper presents a new approach to tackle this problem by controlling damping of the resonator. Another aim is to analyze why one common anti-windup strategy for PI-controllers, that reduces the input of the integrator, also works for PR-controllers. Even though the proposed damping anti-windup showed a somewhat lesser performance than the conventional one, it ensured stability. The newly proposed strategy is inherently stable and thus easy to tune. In particular, it is a reliable anti-windup for DSP-controlled converters.
Neurogenetics of vesicular transporters in C. elegans

The nematode Caenorhabditis elegans has a number of advantages for the analysis of synaptic molecules. These include a simple nervous system in which all cells are identified and synaptic connectivity is known and reproducible, a large collection of mutants and powerful methods of genetic analysis, simple methods for the generation and analysis of transgenic animals, and a number of relatively simple quantifiable behaviors. Studies in C. elegans have made major contributions to our under‐standing of vesicular transmitter transporters. Two of the four classes of vesicular transporters so far identified (VAChT and VGAT) were first described and cloned in C. elegans; in both cases, the genes were first identified and cloned by means of muta¬tions causing a suggestive phenotype (1, 2). The phenotypes of eat‐4 mutants and the cell biology of the EAT‐4 protein were critical in the identification of this protein as the vesicular glutamate transporter (3, 4). In addition, the unusual gene structure asso¬ciated with the cholinergic locus was first described in C. elegans (5). The biochemical properties of the nematode transporters are surprisingly similar to their vertebrate counterparts, and they can be as¬sayed under similar conditions using the same types of mammalian cells (6, 7). In addition, mild and severe mutants (including knockouts) are available for each of the four C. elegans vesicular transporters, which has permitted a careful evaluation of the role(s) of vesicular transport in transmitter‐specific behaviors. Accordingly, it seems appropriate at this time to present the current status of the field. In this review, we will first discuss the properties of C. elegans vesicular transporters and transporter mu¬tants, and then explore some of the lessons and insights C. elegans research has provided to the field of vesicular transport. —Rand, J.

Consistent Energy-Based Atomistic/Continuum Coupling for Two-Body Potentials in Three Dimensions

Very few works exist to date on development of a consistent energy-based coupling of atomistic and continuum models of materials in more than one dimension. The difficulty in constructing such a coupling consists in defining a coupled energy whose minimizers are free from uncontrollable errors on the atomistic/continuum interface. In this paper a consistent coupling in three dimensions is proposed. The main achievement of this work is in identifying and efficiently treating a modified Cauchy--Born continuum model which can be coupled to the exact atomistic model. The convergence and stability of the method is confirmed with numerical tests.
ADP Ribosylation Factors 1 and 4 and Group VIA Phospholipase A2 Regulate Morphology and Intraorganellar Traffic in the Endoplasmic Reticulum–Golgi Intermediate Compartment

In search of morphological determinants for the endoplasmic reticulum-Golgi intermediate compartment (ERGIC), we found that a concerted action of Arf1, Arf4, and PLA2G6-A controls the architecture of the ERGIC by regulating tubular carriers. This is predicted to impact the rate of transport and destination of cargos in the ERGIC.
Behind Every High Earning Man is a Conscientious Woman: A Study of the Impact of Spousal Personality on Wages

This paper explores the effects of a spouse's personality on earnings. We build on the growing literature spanning economics and psychology that investigates how personality traits affect one's own individual earnings. In particular, several of the big five personality characteristics (extraversion, agreeableness, conscientiousness, neuroticism and openness) have been shown to be predictors of own earnings. To our knowledge only one paper studies the relationship between spousal personality and labor market outcomes finding a strong correlation between the two. We extend this work to assess the linkage between spousal personality and earnings while accounting for the potential endogeneity of the selection into marriage. Using the Household, Income and Labor Dynamics in Australia Survey from 2001â€ 2013, we test which spousal personality characteristics affect earnings. Our results indicate that for men, having a conscientious wife raises his earnings while there is little consistent effect of husband's personality on his wife's earnings.
Migration and DNA methylation: a comparison of methylation patterns in type 2 diabetes susceptibility genes between indians and europeans

Background Type 2 diabetes is a global problem that is increasingly prevalent in low and middle income countries including India, and is partly attributed to increased urbanisation. Genotype clearly plays a role in type 2 diabetes susceptibility. However, the role of DNA methylation and its interaction with genotype and metabolic measures is poorly understood. This study aimed to establish whether methylation patterns of type 2 diabetes genes differ between distinct Indian and European populations and/or change following rural to urban migration in India. Methods Quantitative DNA methylation analysis in Indians and Europeans using Sequenom® EpiTYPER® technology was undertaken in three genes: ADCY5, FTO and KCNJ11. Metabolic measures and genotype data were also analysed. Results Consistent differences in DNA methylation patterns were observed between Indian and European populations in ADCY5, FTO and KCNJ11. Associations were demonstrated between FTO rs9939609 and BMI and between ADCY5rs17295401 and HDL levels in Europeans. However, these observations were not linked to local variation in DNA methylation levels. No differences in methylation patterns were observed in urban-dwelling migrants compared to their non-migrant rural-dwelling siblings in India. Conclusions Analysis of DNA methylation at three type 2 diabetes susceptibility loci highlighted geographical and ethnic differences in methylation patterns. These differences may be attributed to genetic and/or region-specific environmental factors.
Invariant approach to flavour-dependent CP-violating phases in the MSSM

We use a new weak basis invariant approach to classify all the observable phases in any extension of the Standard Model (SM). We apply this formalism to determine the invariant CP phases in a simplified version of the Minimal Supersymmetric SM with only three non-trivial flavour structures. We propose four experimental measures to fix completely all the observable phases in the model. After these phases have been determined from experiment, we are able to make predictions on any other CP-violating observable in the theory, much in the same way as in the Standard Model all CP-violation observables are proportional to the Jarlskog invariant.
THE HIGH-MASS END OF THE BLACK HOLE MASS FUNCTION: MASS ESTIMATES IN BRIGHTEST CLUSTER GALAXIES

We present Hubble Space Telescope imaging and spectroscopic observations of three Brightest Cluster Galaxies, Abell 1836-BCG, Abell 2052-BCG, and Abell 3565-BCG, obtained with the Wide Field and Planetary Camera 2, the Advanced Camera for Surveys and the Space Telescope Imaging Spectrograph. The data provide detailed information on the structure and mass profile of the stellar component, the dust optical depth, and the spatial distribution and kinematics of the ionized gas within the innermost region of each galaxy. Dynamical models, which account for the observed stellar mass profile and include the contribution of a central supermassive black hole (SBH), are constructed to reproduce the kinematics derived from the Hα and [N ii]λλ6548,6583 emission lines. Secure SBH detection with M• = 3.61+0.41−0.50 × 109M☉ and M• = 1.34+0.21−0.19 × 109M☉, respectively, are obtained for Abell 1836-BCG and Abell 3565-BCG, which show regular rotation curves and strong central velocity gradients. In the case of Abell 2052-BCG, the lack of an orderly rotational motion prevents a secure determination, although an upper limit of M• ≲ 4.60 × 109 M☉ can be placed on the mass of the central SBH. These measurements represent an important step forward in the characterization of the high-mass end of the SBH mass function.
A comparison of high-risk sexual behaviour and HIV testing amongst a bar-going sample of homosexual men in London and Edinburgh.

BACKGROUND This study compared high-risk sexual and HIV testing behaviour amongst homosexual men recruited from gay bars in London and Edinburgh. METHODS A cross-sectional survey monitoring high-risk sexual and HIV testing behaviour using a self-completed questionnaire was conducted in November and December 1996. RESULTS Two thousand, three hundred and ninety-seven questionnaires were returned (1,366 recruited in London and 1,031 in Edinburgh), with a response rate of 77%. A larger proportion of men surveyed in London had had unprotected anal intercourse (UAI) with one or more male partners in the previous year (35%) than in Edinburgh (30%). Men recruited in Edinburgh were less likely to have had an HIV test (54%) than men in London (63%). In both surveys, 25% of men who reported UAI with partners of the same HIV status as themselves also reported never having had an HIV test. CONCLUSIONS The observed dissimilarities in the HIV epidemic in the two cities may be accounted for by the differences in self-reported high-risk sexual and HIV testing behaviours between the two populations. A large proportion of men in both cities continue to engage in high-risk sexual behaviour suggesting continued transmission of HIV in these populations. Thus, there is a continued need for innovative and relevant health promotion amongst homosexual men in the UK.
A mixture model-based strategy for selecting sets of genes in multiclass response microarray experiments

MOTIVATION Multiclass response (MCR) experiments are those in which there are more than two classes to be compared. In these experiments, though the null hypothesis is simple, there are typically many patterns of gene expression changes across the different classes that led to complex alternatives. In this paper, we propose a new strategy for selecting genes in MCR that is based on a flexible mixture model for the marginal distribution of a modified F-statistic. Using this model, false positive and negative discovery rates can be estimated and combined to produce a rule for selecting a subset of genes. Moreover, the method proposed allows calculation of these rates for any predefined subset of genes. RESULTS We illustrate the performance our approach using simulated datasets and a real breast cancer microarray dataset. In this latter study, we investigate predefined subset of genes and point out interesting differences between three distinct biological pathways. AVAILABILITY http://www.bgx. org.uk/software.html
Galactic Bulges from Hubble Space Telescope NICMOS Observations: Central Galaxian Objects, and Nuclear Profile Slopes

We have measured the central structural properties for a sample of S0-Sbc galaxies down to scales of ~10 pc using Hubble Space Telescope NICMOS images. Central star clusters are found in 58% of our sample. Their near-infrared luminosities scale with the host bulge luminosities, as reported in 2003 by Balcells and coworkers. In terms of photometric masses, the relation is ℳPS = 107.75±0.15 (ℳbul/1010ℳ☉)0.76±0.13. Put together with recent data on bulges hosting supermassive black holes, we infer a nonlinear dependency of the "central massive object" mass on the host bulge mass such that ℳCMO/ℳ☉ = 107.51±0.06(ℳbul/1010 ℳ☉)0.84±0.06. The linear relation presented by Ferrarese and coworkers may be biased at the low-mass end by the inclusion of the disk light from cluster lenticular galaxies. Bulge-disk decompositions reaching to the outer disk show that ~90% of our galaxies possess central light excesses that can be modeled with an inner exponential and/or an unresolved source. All the extended nuclear components, with sizes of a few hundred parsecs, have disky isophotes, which suggest that they may be inner disks, rings, or bars; their colors are redder than those of the underlying bulge, arguing against a recent origin for their stellar populations. Surface brightness profiles (of the total galaxy light, and the bulge component on its own) rise inward to the resolution limit of the data, with a continuous distribution of logarithmic slopes from the low values typical of dwarf ellipticals (0.1 ≤ γ ≤ 0.3) to the high values (γ ~ 1) typical of intermediate-luminosity ellipticals; the nuclear slope bimodality reported by others is not present in our sample.
2-1-2010 H-Matrix-Based Fast Direct Finite Element Solver for Large-Scale Electromagnetic Analysis

In this work, we prove that the sparse matrix resulting from a finite-element-based analysis of electrodynamic problems can be represented by an -matrix without any approximation, and the inverse of this sparse matrix has a data-sparse matrix approximation with error well controlled. Based on this proof, we develop an -matrix-based direct finite-element solver of O(kNlogN) memory complexity and O(kNlogN) time complexity for solving electromagnetic problems, where k is a small variable that is adaptively determined based on accuracy requirements, and N is the number of unknowns. Both inverse-based and LU-based direct solutions are developed. The LU-based solution is further accelerated by nested dissection. Both theoretical analysis and numerical experiments have demonstrated the accuracy and almost linear complexity of the proposed solver in large-scale electrostatic and electrodynamic applications involving over 1 million unknowns. A comparison with the state-of-the-art direct finite element solver that employs the most advanced sparse matrix solution has shown clear advantages of the proposed solver. In addition, the proposed solver is applicable to arbitrarily-shaped threedimensional structures and arbitrary inhomogeneity.
Comparative Microsatellite Typing of New World Leishmania infantum Reveals Low Heterogeneity among Populations and Its Recent Old World Origin

Leishmania infantum (syn. L. chagasi) is the causative agent of visceral leishmaniasis (VL) in the New World (NW) with endemic regions extending from southern USA to northern Argentina. The two hypotheses about the origin of VL in the NW suggest (1) recent importation of L. infantum from the Old World (OW), or (2) an indigenous origin and a distinct taxonomic rank for the NW parasite. Multilocus microsatellite typing was applied in a survey of 98 L. infantum isolates from different NW foci. The microsatellite profiles obtained were compared to those of 308 L. infantum and 20 L. donovani strains from OW countries previously assigned to well-defined populations. Two main populations were identified for both NW and OW L. infantum. Most of the NW strains belonged to population 1, which corresponded to the OW MON-1 population. However, the NW population was much more homogeneous. A second, more heterogeneous, population comprised most Caribbean strains and corresponded to the OW non-MON-1 population. All Brazilian L. infantum strains belonged to population 1, although they represented 61% of the sample and originated from 9 states. Population analysis including the OW L. infantum populations indicated that the NW strains were more similar to MON-1 and non-MON-1 sub-populations of L. infantum from southwest Europe, than to any other OW sub-population. Moreover, similarity between NW and Southwest European L. infantum was higher than between OW L. infantum from distinct parts of the Mediterranean region, Middle East and Central Asia. No correlation was found between NW L. infantum genotypes and clinical picture or host background. This study represents the first continent-wide analysis of NW L. infantum population structure. It confirmed that the agent of VL in the NW is L. infantum and that the parasite has been recently imported multiple times to the NW from southwest Europe.
Converter Structure-Based Power Loss and Static Thermal Modeling of The Press-Pack IGBT Three-Level ANPC VSC Applied to Multi-MW Wind Turbines

Wind turbine converters demand high power density due to nacelle space limitation and high reliability due to high maintenance cost. Depending on the converter structure, the converter thermal performance determines the converter power density and reliability. To estimate the converter thermal performance, the converter structure-based power loss and thermal models are developed in this study for the medium-voltage (MV) three-level active neutral-point-clamped voltage source converter (3L-ANPC-VSC) utilizing 4500 V-1800 A press-pack insulated-gate bipolar transistor-diode pairs and interfacing a 6 MW wind turbine to a MV grid. The switching power loss models are built using the experimental switching power loss data acquired via the double-pulse tests conducted on a full-scale 3L-ANPC-VSC prototype. The converter static thermal model is developed based on the double-sided water-cooled press-pack switches. Via a single-phase test setup with two full-scale 3L-ANPC-VSC legs, the developed power loss and thermal models are validated experimentally. Employing the validated models, the 3L-ANPC-VSC's thermal performance is demonstrated on simulation for a 6 MW wind turbine grid interface. Hence, these converter structure-based models developed and validated in this study are proven to be suitable for the converter power density and reliability studies based on converter thermal performance.
