Different risk factors for musculoskeletal complaints and musculoskeletal sickness absence.

OBJECTIVES The aim of this study was to investigate whether individual, work-related physical and psychosocial risk factors involved in the occurrence of musculoskeletal complaints also determine musculoskeletal sickness absence. METHODS This cross-sectional study used a self-administered questionnaire to collect data on individual and work-related risk factors and the occurrence of musculoskeletal complaints and musculoskeletal sickness absence among 373 employees of laundry-works and dry-cleaning establishments (response rate 87%). Logistic regression models were used to determine associations between risk factors and the occurrence of musculoskeletal complaints and sickness absence due to these complaints. RESULTS Both work-related physical and psychosocial factors showed strong associations with low-back pain and upper-extremity complaints. Work-related physical factors did not influence sickness absence, whereas psychosocial factors showed some associations with sickness absence. Sickness absence was associated with The Netherlands as the country of birth [odds ratio (OR) 0.3, 95% confidence interval (95% CI) 0.2-0.6], and female workers had an episode of sickness absence due to low-back pain less often (OR 0.5, 95% CI 0.3-0.9), but more often due to upper-extremity complaints (OR 2.2, 95% CI 1.14.5). CONCLUSIONS Work-related physical and psychosocial factors largely determine the occurrence of low-back pain and upper-extremity complaints, whereas individual factors predominantly determine whether persons with these musculoskeletal complaints take sick leave.
Regulated Expression of the Apolipoprotein E/C-I/C-IV/C-II Gene Cluster in Murine and Human Macrophages

Lipid-loaded macrophage “foam cells” accumulate in the subendothelial space during the development of fatty streaks and atherosclerotic lesions. To better understand the consequences of such lipid loading, murine peritoneal macrophages were isolated and incubated with ligands for two nuclear receptors, liver X receptor (LXR) and retinoic acid receptor (RXR). Analysis of the expressed mRNAs using microarray technology led to the identification of four highly induced genes that encode apolipoproteins E, C-I, C-IV, and C-II. Northern blot analysis confirmed that the mRNA levels of these four genes were induced 2–14-fold in response to natural or synthetic ligands for LXR and/or RXR. The induction of all four mRNAs was greatly attenuated in peritoneal macrophages derived from LXRα/β null mice. The two LXR response elements located within the multienhancers ME.1 and ME.2 were shown to be essential for the induction of apoC-II promoter-reporter genes by ligands for LXR and/or RXR. Finally, immunohistochemical studies demonstrate that apoC-II protein co-localizes with macrophages within murine arterial lesions. Taken together, these studies demonstrate that activated LXR induces the expression of the apoE/C-I/C-IV/C-II gene cluster in both human and murine macrophages. These results suggest an alternative mechanism by which lipids are removed from macrophage foam cells.
Multidisciplinary Approach for Restoring Function and Esthetics in a Patient with Amelogenesis Imperfecta: A Clinical Report

Amelogenesis imperfecta has been defined as a group of hereditary enamel defects which may or may not be associated with some other dental and skeletal developmental defects. It can be characterized by enamel hypoplasia, hypomaturation, or hypo-calcification of the teeth. This clinical report describes the oral rehabilitation of a twenty two year old female patient with amelogenesis imperfecta complicated by periodontal problems . The specific objectives of this treatment were to enhance aesthetics, eliminate tooth sensitivity and restore masticatory function.
Recent Trends in Microbiological Safety of Fruits and Vegetables

The number of documented outbreaks of human infections associated with the consumption of raw fruits, vegetables, and unpasteurized fruit juices has increased in recent years. According to the Centers for Disease Control and Prevention, in the U.S. the number of reported produce-related outbreaks per year doubled between the period 1973-1987 and 1988-1992 (2,24). During both time periods, the etiologic agent was unknown in more than 50% of outbreaks. Outbreaks with identified etiology were predominantly of bacterial origin, primarily
The Multidimensional Perfectionism Scale: Correlations with Depression in College Students with Learning Disabilities

Interpretations of depression in children and adolescents with learning disabilities have tended to be neuropsychological or motivational. Some research has related various cognitive-behavioral constructs with depression and other problematic outcomes for this population. Research with nonlearning-disabled college students has provided correlations for scores on the Self-oriented and the two social scales of the Multidimensional Perfectionism Scale with those on depression. No such work has been done with college students having learning disabilities. Measures for multidimensional perfectionism, anxiety, and depression were administered to 110 learning-disabled undergraduate men and women. Analysis showed that scores on only one of the social scales of perfectionism were positively correlated with depression scores, and this relation was weaker than previously found for nonlearning-disabled students. Findings are discussed in terms of previous research and a motivational interpretation of depression in learning-disabled college students.
Theory and Application of Software Defined Electronics: Design Concepts for the Next Generation of Telecommunications and Measurement Systems

The analog signal processing is substituted everywhere by its digital counterpart because of its higher accuracy and flexibility, its much lower cost and because in digital signal processing there is no need for regular calibration as it is required in the analog systems. The most important feature of digital approach is that the HW and SW components can be fully separated and the same HW, referred to as a universal HW device, can be used to implement very different applications. Although digital signal processing has been around everywhere in the low frequency applications for many years, until this time it could not satisfy the requirements of RF and microwave engineering. The main challenges in RF and microwave radio communications and measurements are: (i) implementation of ultra wide dynamic range (limited by the quantization noise and linearity) and (ii) minimize sampling rate required. In our time the situation is changing rapidly. Software Defined Radio, Universal Software Radio Peripheral and Virtual Instrumentation all mean that a universal HW device is used to extract the complex envelope of an RF bandpass signal to be demodulated or analyzed, and the implementation of radio receiver or signal analyzer is implemented entirely in SW. The complex envelope, processed in SW, carries all information available in the RF signal and assures the minimum sampling rate which is determined by the bandwidth of RF signal. The complex envelope represents fully the RF bandpass signal without any distortion and every RF bandpass signal can be reconstructed from its complex envelope without any distortion. This tutorial surveys the theory of complex envelopes, shows how the baseband equivalent models of RF systems can be derived and demonstrates how different radio transceivers and test equipment can be implemented by means of the same universal RF HW device in the 2.4-GHz ISM frequency band.
Location Based Social Networks – Definition, Current State of the Art and Research Agenda

The growing penetration of GPS equipped smartphones allowing users to constantly share geographic information on their current whereabouts has led the way to an augmentation of existing Social Network Sites with location‐based features or the creation of new ones exclusively around geographic information. Within these Location Based Social Networks vast amounts of geographic information are allocated, which attracted the attention of researchers with various scientific backgrounds. This article presents a comprehensive definition of this special type of Social Network Site and an overview of research activities, which are currently conducted using the data. Finally, a research agenda for GIScience is drawn from existing research directions.
Annealing-induced properties of Al-N-M (M: Co, Fe) thin films

In this study, we focus on nanocrystalline granular films in which small metal particle of nanometer size are embedded in an insulator matrix. We present here annealing induced magnetic and electric properties for the films with different compositions. The structure and the microstructure of these films were examined by X-ray diffraction and transmission electron microscopy. Magnetic and electrical properties were measured by a vibrating sample magnetometer and a four-probe method respectively.
Physical layer security for multi-user MIMO systems

T his thesis studies physical layer security for multi-user multiple-input multiple-output (MIMO) wireless systems. Due to the broadcast nature of the physical medium, wireless multi-user communications are very susceptible to eavesdropping, and it is critical to protect the transmitted information. Security of wireless communications has traditionally been achieved at the network layer with cryptographic schemes. However, classical cryptography might not be suitable in large dynamic networks, since it requires key distribution and management, and complex encryption/decryption algorithms. A method that exploits the characteristics of wireless channels, known as physical layer security, was proposed as an alternative to achieve perfect secrecy without requiring encryption keys. The rates at which messages can be reliably transmitted to an intended user while no information is leaked at the eavesdroppers, denoted as the secrecy rates, have been studied for several network topologies. However, the secrecy rates achievable in generic multiuser networks are still unknown. Hence in this thesis we study the secrecy rates achievable in multi-user systems with practical transmission schemes. We propose a linear precoder based on regularized channel inversion (RCI) for the broadcast channel with confidential messages (BCC). In the BCC, a multi-antenna base station (BS) simultaneously transmits independent confidential messages to several spatially dispersed malicious users that can eavesdrop on each other. We carry out a large-system analysis and obtain closed form expressions for the achievable secrecy rates under Rayleigh fading, as well as the optimal regularization parameter and the optimal network load. Simulations confirm that our analysis is accurate even for finite systems. We compare the secrecy rate of the proposed precoder to two upper bounds obtained without secrecy requirements and without interference, respectively, and show that it has the same scaling factor as the two bounds in the high signal-to-noise ratio (SNR) regime. We further extend our analysis to more practical scenarios where only imperfect channel state information is available at the BS, and where channel correlation is present among the transmit antenna elements. We then introduce the broadcast channel with confidential messages and external eavesdroppers (BCCE). Unlike the BCC, in the BCCE not just malicious users, but also randomly located external nodes can act as eavesdroppers. We obtain the probability of secrecy outage and the mean secrecy rate for the RCI precoder in the BCCE, for the two cases of non-colluding and colluding eavesdroppers. We show that, irrespective of the collusion strategy at the external eavesdroppers, a large number of transmit antennas drives both the probability of secrecy outage and the rate loss due to the presence of external eavesdroppers to zero. Increasing the density of eavesdroppers by a factor n, requires n2 as many antennas to meet a given probability of secrecy outage and a given
Imaging-based classification algorithms on clinical trial data with injected tumour responses

Current microwave breast cancer imaging algorithms focus primarily on generating an image, and provide little machinery for interpretation of the image. Within-image contrast is commonly used as a performance metric, but a better reflection of the tumour detection capability of an algorithm is the difference between the maximum voxel intensities observed in images from scans of tumour-free and tumour-bearing breasts. This paper extends existing imaging algorithms by incorporating an automatic tumour detection technique that involves classification based on maximum voxel intensities. We compare results obtained from different algorithms on the data collected from healthy breast scans performed during clinical trials of a microwave radar system. We artificially inject tumour signals that are constructed based on the transmission properties of the radar system and the estimated breast tissue properties. The results provide insights into which algorithms are sufficiently robust to handle discrepancies between the real measurement data and the modeling assumptions.
How degrading: Cyp26s in hindbrain development

The vitamin A derivative retinoic acid performs many functions in vertebrate development and is thought to act as a diffusible morphogen that patterns the anterior–posterior axis of the hindbrain. Recent work in several systems has led to insights into how the spatial distribution of retinoic acid is regulated. These have shown local control of synthesis and degradation, and computational models suggest that degradation by the Cyp26 enzymes plays a critical role in the formation of a morphogen gradient as well as its ability to compensate for fluctuations in RA levels.

Constriction of the ductus arteriosus, severe right ventricular hypertension, and a right ventricular aneurysm in a fetus after maternal use of a topical treatment for striae gravidarum

Abstract Fetal constriction of the ductus arteriosus is a complication of maternal non-steroidal anti-inflammatory drug use and polyphenol-rich food intake. It is unclear as to whether polyphenol-containing topical treatments have similar effects. We present a case of fetal constriction of the ductus arteriosus, severe right ventricular hypertension, and a right ventricular aneurysm associated with maternal use of a topical treatment for striae gravidarum.
Density and affinity of the dopamine D2 receptors in aged symptomatic and asymptomatic MPTP‐treated monkeys: PET studies with [11C]raclopride

We reported earlier on the binding of [C]-raclopride to the D2 receptors in monkeys with 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP)-induced lesions of the dopaminergic (DA) nigrostriatal system (Doudet et al., 2000). As expected, the binding potential (BP: an estimate or equivalent of Bmax/Kd) was increased in monkeys exhibiting rigidity, bradykinesia, and hypokinesia but was decreased or normal in animals with confirmed lesions (as assessed with 6-[F]fluoro-L-dopa (Doudet et al., 1998a)) but without parkinsonian symptoms. This result, however, is of limited value to understand the adaptative mechanisms occurring in the striatum in response to DA neurodegeneration. Indeed, a change in BP could be the result of a change in Bmax, Kd, or both. Alternatively, no change in BP does not necessarily indicate no change in receptor binding, since a simultaneous change in both Bmax and Kd could lead to no apparent change in BP. In the present study, we analyzed in vivo the density and affinity of the D2 receptors in a representative subgroup of the animals, normals, asymptomatic, and symptomatic MPTP-treated monkeys. Classical in vitro scatchard studies and one in vivo PET study have shown an increase in receptor density in early, untreated parkinsonism (Rinne et al., 1995) but none has addressed the status of the D2 receptors in the preceding preclinical period or in long-term untreated parkinsonism.
Investigation on properties of transmission spectra for Bulls-eye structure based on CNT film

In order to present an exhaustive exploration of the optical properties of a Bulls-eye structure consisting of a circular annular aperture surrounded with several concentric periodic grooves in a conductor film, we calculated and analyzed a series of transmission spectra of the proposed structure in terahertz (THz) range and demonstrate that the number of grooves, the depth of grooves, the width of grooves and the conductivity of film material are several important factor of the peak value of transmission spectra. The results obtained not only describe the effect of the geometry parameters of Bulls-eye structures on the transmission properties in detail, but also point out the direction to further optimum design to get the most efficiency Bulls-eye structure.
Rat Brain p64H1, Expression of a New Member of the p64 Chloride Channel Protein Family in Endoplasmic Reticulum*

Many plasma membrane Cl−channels have been cloned, including the cystic fibrosis transmembrane conductance regulator and several members of the voltage-gated ClC family. In contrast, very little is known about the molecular identity of intracellular Cl− channels. We used a polymerase chain reaction-based approach to identify candidate genes in mammalian brain and cloned the cDNA corresponding to rat brain p64H1. This encoded a microsomal membrane protein of predictedM r 28,635 homologous to the putative intracellular bovine kidney Cl− channel p64. In situ mRNA hybridization histochemistry showed marked expression in hippocampus and cerebellum, and in vitroexpression revealed a large cytoplasmic domain, one membrane-spanning segment, and a small nonglycosylated N-terminal luminal domain. The predicted protein contained consensus phosphorylation sites for protein kinase C and protein kinase A, and protein kinase C-mediated phosphorylation increased the M r of p64H1 to ∼43,000, characteristic of the native protein in Western blots. Recombinant p64H1 was immunolocalized to the endoplasmic reticulum of human embryonic kidney 293 and HT-4 cells, and incorporation of human embryonic kidney 293 endoplasmic reticulum vesicles into planar lipid bilayers gave rise to intermediate conductance, outwardly rectifying anion channels. Although p64H1 is the first intracellular Cl− channel component or regulator to be identified in brain, Northern blotting revealed transcripts in many other rat tissues. This suggests that p64H1 may contribute widely to intracellular Cl− transport.
Ultra-high-spectral-efficiency transmission

We discuss the generation, transmission, and coherent detection of 14-Gbaud polarization-division multiplexed, 16-ary quadrature-amplitude-modulation (16-QAM) signals (112-Gb/s line rate). We attain 630-km and 1020-km wavelength-division-multiplexed transmission with spectral efficiencies of 6.2 b/s/Hz and 4.1 b/s/Hz, respectively.
IMAGE STABILIZATION WITH BEST SHOT SELECTOR AND SUPER RESOLUTION RECONSTRUCTION

In this paper, we present an image stabilization algorithm based on Nikon’s Best Shot Selector [11]. We implement Best Shot Selector and use super resolution concept to reconstruct blurred images. Image stabilization includes optical and digital methods. Optical stabilization applies gyroscopic sensors and corrective lens to compensate camera shake optically. Digital stabilization applies image processing algorithms to restore motion blurs. Best Shot Selector avoids the risk of capturing blurred images by sequential capturing and selection. Furthermore, super resolution reconstruction combines images into a sharper image even if the result image of Best Shot Selector is blurred. The experiment results show that our image stabilization algorithm indeed selects and enhances the sharpest image.
Categorizing Externally Distributed Stimulus Samples for Unequal Molar Probabilities

40 Ss categorized random samples from one of two normal distributions and then received feedback. The over-all, molar probabilities of samples for the two distributions were . 35 and . 65. Problem-solving or Gambling instructions, and distributions on a Dot position or a Number continuum, were combined factorially with sex. There were no main instructional effects. Performance was superior on the position continuum (p < .01). Over-all performance resembled micromatching of probabilities at each continuum position, but some Ss responded independently of sample position. The molar probability of response “1” for the Dot group was less (.295) than the molar reinforcement level (p < .001). There were no main sex effects. Distance between centers was overestimated for Dot but not for the Number continuum.
Genomic resources in fruit plants: an assessment of current status

Abstract The availability of many genomic resources such as genome sequences, functional genomics resources including microarrays and RNA-seq, sufficient numbers of molecular markers, express sequence tags (ESTs) and high-density genetic maps is causing a rapid acceleration of genetics and genomic research of many fruit plants. This is leading to an increase in our knowledge of the genes that are linked to many horticultural and agronomically important traits. Recently, some progress has also been made on the identification and functional analysis of miRNAs in some fruit plants. This is one of the most active research fields in plant sciences. The last decade has witnessed development of genomic resources in many fruit plants such as apple, banana, citrus, grapes, papaya, pears, strawberry etc.; however, many of them are still not being exploited. Furthermore, owing to lack of resources, infrastructure and research facilities in many lesser-developed countries, development of genomic resources in many underutilized or less-studied fruit crops, which grow in these countries, is limited. Thus, research emphasis should be given to those fruit crops for which genomic resources are relatively scarce. The development of genomic databases of these less-studied fruit crops will enable biotechnologists to identify target genes that underlie key horticultural and agronomical traits. This review presents an overview of the current status of the development of genomic resources in fruit plants with the main emphasis being on genome sequencing, EST resources, functional genomics resources including microarray and RNA-seq, identification of quantitative trait loci and construction of genetic maps as well as efforts made on the identification and functional analysis of miRNAs in fruit plants.
Transfer learning for predictive models in MOOCs

Predictive models are crucial in enabling the personalization of student experiences in Massive Open Online Courses. For successful real-time interventions, these models must be transferable that is, they must perform well on a new course from a different discipline, a different context, or even a different MOOC platform. In this thesis, we first investigate whether predictive models "transfer" well to new courses. We then create a framework to evaluate the "transferability" of predictive models. We present methods for overcoming the biases introduced by specific courses into the models by leveraging a multi-course ensemble of models. Using 5 courses from edX, we show a predictive model that, when tested on a new course, achieved up to a 6% increase in AUCROC across 90 different prediction problems. We then tested this model on 10 courses from Coursera (a different platform) and demonstrate that this model achieves an AUCROC of 0.8 across these courses for the problem of predicting dropout one week in advance. Thus, the model "transfers" very well. Thesis Supervisor: Kalyan Veeramachaneni Title: Principal Research Scientist, Institute for Data, Systems and Society, CSAIL
