Joint Matrix-Tensor Factorization for Knowledge Base Inference

While several matrix factorization (MF) and tensor factorization (TF) models have been proposed for knowledge base (KB) inference, they have rarely been compared across various datasets. Is there a single model that performs well across datasets? If not, what characteristics of a dataset determine the performance of MF and TF models? Is there a joint TF+MF model that performs robustly on all datasets? We perform an extensive evaluation to compare popular KB inference models across popular datasets in the literature. In addition to answering the questions above, we remove a limitation in the standard evaluation protocol for MF models, propose an extension to MF models so that they can better handle out-of-vocabulary (OOV) entity pairs, and develop a novel combination of TF and MF models. We also analyze and explain the results based on models and dataset characteristics. Our best model is robust, and obtains strong results across all datasets.
Lead, mercury, and organochlorine compound levels in cord blood in Québec, Canada.

We conducted this study to evaluate blood levels of lead, mercury, and organochlorine compounds in newborns in the Province of Quebec. During 1993 to 1995, we carried out a survey in 10 hospitals located in southern Quebec. During that time, umbilical cord blood samples were obtained from 1109 newborns, and we analyzed each for lead, mercury, 14 polychlorinated biphenyl congeners, and 11 chlorinated pesticides. We used the geometric mean and 95% confidence interval (CI) to describe the results. Mean concentrations of lead and mercury in cord blood were 0.076 micromol/l (95% CI = 0.074, 0.079) and 4.82 nmol/l (95% CI = 4.56, 5.08), respectively. The mean concentrations of total polychlorinated biphenyls (Aroclor 1260) and dichlorodiphenyl dichloroethylene were 0.514 microg/I (95% CI = .493, 0.536) and 0.412 microg/l (95% CI = 0.390, 0.435), respectively. We observed a statistically significant relationship between maternal age and cord blood concentrations of (a) lead, (b) mercury, (c) polychlorinated biphenyls, and (d) dichlorodiphenyl dichloroethylene. In addition, maternal smoking during pregnancy was associated with cord blood lead levels. The cord blood concentrations of lead, mercury, polychlorinated biphenyls, and dichlorodiphenyl dichloroethylene we measured in our study were the lowest levels recently reported in industrialized countries. The results of this study underline the role of public health authorities in the evaluation of biological levels of environmental contaminants among children for the assessment of risk of adverse health effects.
Effect of dielectrophoretic forces on nanoparticles

We have investigated the long term stability of nanofluids exposed to strong divergent fields. The nanofluids were made of conductive nanoparticles (magnetite) dissolved in a base transformer mineral oil. The results show that, due to dielectrophoretic forces, nanoparticles aggregation takes place under DC fields with modalities associated with the polarity of the applied voltage. Under AC fields, aggregation is still possible, but the fields needed are above streamer inception voltage. Comsol simulations and simplified analytical models are provided to investigate the nanoparticle concentration dynamics. The models confirm the role of dielectrophoretic forces as a driver for nanoparticle aggregation.
Particle Distributions in a Block Copolymer Nanocomposite

Self-consistent-field theory is used to predict the center-of-mass distribution of spherical nanoparticles embedded in the lamellar phase of a diblock copolymer melt. The calculation is performed in the dilute limit, where the particle-particle interactions have a negligible effect on the distribution. We investigate how the distribution is affected by particle radius R, surface affinity ⁄N, diblock segregation N, diblock composition f, and invariant polymerization index N h . While the preferred location of the particles (i.e., interface or domain center) is primarily controlled by ⁄N, the degree of particle localization depends on several factors. Larger values of R, N, and N h all tend to produce narrower particle distributions.
Analysis & characterization of dual tail current based dynamic latch comparator with modified SR latch using 90nm technology

This paper presents characterization of low operating voltage, high speed and power efficient comparator used as a basic building block in speed optimized Analog to Digital Converters (ADC), such as flash ADC. Overall performance of any ADC in terms of speed, resolution and power consumption highly depends on the underlying comparator being used. In this paper, better structure of comparator is implemented and analyzed, which is a combination of modified SR latch and sense amplifier. The comparator is built up by preamplifier and positive feedback latch (back-to-back connected inverter) to enhance the speed. The output of latch is given to the modified SR latch, which provides stable output signal compare to that of conventional dynamic latch structure. The implementation is carried out in 90nm technology in Mentor Graphics' IC Studio tool and simulation is done in Eldo tool.
The dynein genes of Paramecium tetraurelia. Sequences adjacent to the catalytic P-loop identify cytoplasmic and axonemal heavy chain isoforms.

Paramecium tetraurelia is a unicellular organism that utilizes both axonemal and cytoplasmic dyneins. The highly conserved region containing the catalytic P-loop of the dynein heavy chain was amplified by RNA-directed polymerase chain reaction. Eight different P-loop-containing cDNA fragments were cloned. Southern hybridization analysis indicated that each fragment corresponds to a separate dynein gene and that there are at least 12 dynein heavy chain genes expressed in Paramecium. Seven of the eight cloned contain sequence motif A, which is found in axonemal dyneins, and one contains sequence motif B, which is found in the dyneins from cell types that do not have cilia or flagella. Two of the Paramecium dynein genes were further investigated: DHC-6 which contains motif A, and DHC-8 which contains motif B. Additional sequencing of the central portions of these genes showed that DHC-6 most closely matches sea urchin ciliary beta heavy chain and DHC-8 is similar to the cytoplasmic dynein from Dictyostelium. Deciliation of the cells resulted in a substantial increase in the steady state concentration of DHC-6 mRNA but only a small change in DHC-8 mRNA. Antisera were produced against synthetic peptides derived from sequence motifs A and B. Competitive solid-phase binding assays demonstrated that each antiserum was peptide-specific. In western blots, the antiserum to motif A reacted with both ciliary and cytoplasmic dyneins. In contrast, the antiserum to motif B reacted with the cytoplasmic dyneins of Paramecium and bovine brain but did not react with ciliary dynein. (ABSTRACT TRUNCATED AT 250 WORDS)
Immune Status of Asymptomatic HIV-Infected Hemophiliacs: Randomized, Prospective, Two-Year Comparison of Treatment with a High-Purity or an Intermediate-Purity Factor VIII Concentrate

Summary It has been postulated that high-purity factor VIII (FVIII) concentrates, since they contain less alloantigenic proteins than intermediate-purity concentrates, might cause lesser deterioration of the immune systems of hemophilic patients infected with the human immunodeficiency virus (HIV). To evaluate this hypothesis, we have prospectively compared T-lymphocytes subsets and delayed hypersensitivity reactions to skin tests in 17 asymptomatic HIV-positive hemophiliacs randomly assigned to continue treatment with an intermediate-purity concentrate with those of 16 hemophiliacs changed to a high-purity concentrate. For both groups, during the 24-month follow-up period CD4 cell counts showed similar rates of fall from baseline values. There was also no difference in the number of patients anergic to skin tests. Three patients treated with the intermediate purity concentrate and one treated with the high-purity concentrate developed symptoms of HIV infection. On the whole, no striking benefit is conferred to the immune status of asymptomatic HIV-positive hemophiliacs by using this high-purity concentrate for 2 years.
Resistin levels in hyperthyroid patients before and after restoration of thyroid function: relationship with body weight and body composition.

BACKGROUND Resistin is a recently discovered peptide hormone that belongs to a family of tissue-specific resistin-like molecules. To date, very few studies have reported on resistin concentrations in hyperthyroid patients, and they present controversial results. OBJECTIVES To undertake a controlled, prospective study to investigate resistin concentrations in hyperthyroidism before and after restoration of euthyroidism and to correlate the results with body weight, body fat, waist circumference and body mass index (BMI). PATIENTS AND METHODS A total of 43 hyperthyroid patients (12 men and 31 women) were investigated, in addition to 23 controls. Anthropometric parameters and resistin concentrations were measured. All the patients commenced taking antithyroid drugs and 3-4 months later the same investigations were performed in 36 of the 43 individuals. RESULTS Hyperthyroid patients exhibited increased resistin concentrations in comparison with controls. Normalization of thyroid hormones was accompanied by a significant decrease in resistin concentration. A sex difference was also found, men showing a significant decrease in resistin concentrations, whereas in women no such difference was found. Resistin concentrations did not correlate with different anthropometric parameters, age and thyroid hormones, either before or after treatment. CONCLUSIONS This study demonstrates for the first time that, although resistin concentrations are increased in hyperthyroidism, they are not associated with body weight, body fat, waist circumference or BMI, which makes it unlikely that resistin plays a crucial part in thermogenesis and energy homeostasis in thyrotoxic patients.
Vitamin D, the immune system and asthma

The effects of vitamin-D on bone metabolism and calcium homeostasis have long been recognized. Emerging evidence has implicated vitamin-D as a critical regulator of immunity, playing a role in both the innate and cell-mediated immune systems. Vitamin-D deficiency has been found to be associated with several immune-mediated diseases, susceptibility to infection and cancer. Recently, there has been increasing interest in the possible link between vitamin-D and asthma. Further elucidation of the role of vitamin-D in lung development and immune system function may hold profound implications for the prevention and treatment of asthma.
Malignant ascites of unknown origin

To determine the clinical characteristics of patients presenting with malignant ascites, as well as means of evaluating the outcome of patients with the disease, a retrospective review was conducted of all cases of malignant peritoneal effusions diagnosed from 1978 to 1987 at a University Hospital and a Veterans Administration Hospital. Of 65 patients with malignant ascites (40 women; 25 men), the primary site was known in 51 cases (80%). Common sites in women were the ovaries, endometrium, and cervix; in men, common sites were the colon, rectum, and stomach. For five women and nine men the primary site was unknown. Median survival from diagnosis was 7.5 days (mean, 43 days; range, 1–256 days). Chest radiograph and abdominal computed tomography (CT) scan did not disclose the occult primary. An occult primary was detected while the patient was alive in only two cases and at autopsy in two other patients. Due to the poor prognosis for this disease, we do not recommend an aggressive approach to malignant ascites of unknown origin, except perhaps in women, in whom ovarian cancer should be suspected.
Assessment of Disease Behavior in Patients with Crohn’s Disease by MR Enterography

Background:Magnetic resonance imaging (MRI) of the bowel is an increasingly used modality to evaluate patients with Crohn’s disease. The Montreal classification of the disease behavior is considered as an excellent prognostic and therapeutic parameter for these patients. In our study, we correlated the behavior assessment performed by a radiologist based on MRI with the surgeons' clinical assessment based on the assessment during abdominal surgery. Methods:We evaluated 76 patients with Crohn’s disease, who underwent bowel resection and had an MRI within 4 weeks before surgery. Radiological behavior assessment was performed by 2 radiologists based on MRI. Behavior was classified into B1 (nonstricturing and nonpenetrating), B2, and B3 (penetrating) disease. Surgical assessment was done by the same surgeon, who performed all bowel resections, based on intraoperative findings and histologic results. Results:The surgical assessment identified 4 patients (5%) as B1, 16 patients (21%) as B2, and 56 patients (74%) as B3. In 97% (n = 74) of all patients, the intraoperative and radiological assessment were identical with interobserver agreement of 0.937. In one case, B2 was radiological considered as B1, and in another case, B3 was diagnosed as B2. The diagnosis of a stricture had the highest sensitivity of 96%, whereas the detection of inflammatory mass showed the lowest sensitivity of 81%. Abscesses had the lowest positive predictive value of 68% with a specificity of 88%. Best correlation was found for fistulae (0.895). Conclusions:MRI represents an excellent imaging modality to correctly assess the Montreal classification–based disease behavior in patients scheduled for bowel resection with Crohn’s disease.
Affective imposition influences risky choice: Handedness points to the hemispheres

The study of risk preference has become a widely investigated area of research. The current study is designed to investigate the relationship between handedness, hemispheric predominance and valence imposition in a risky-choice decision task. Research into the valence hypothesis (e.g., Ahern & Schwartz, 1985; Davidson, 1984) has shown that the left hemisphere is more active in processing positively valenced stimuli, whereas the right hemisphere is more active in processing negatively valenced stimuli. A total of 520 individuals (343 female, 117 male) participated in a self-imposed framing task and took a degree of handedness questionnaire. The results of the framing task and handedness questionnaire showed that participants' degree of handedness significantly influenced the positive/negative valence they imposed onto the framing task as well as their level of risk preference.
Understanding the "Mommy Tracks" : A Framework for Analyzing Work-Family Balance in the IT Workforce

Despite the recent growth in the number of women in the American labor force, women are still under-represented in the IT workforce. Key among the factors that account for this under-representation is balancing work-family issues. This article presents a framework for analyzing work-family balance from a field study of women employed in the American IT workforce. The findings are examined through the lens of the Individual Differences Theory of Gender and IT to show the range of ways in which work-family considerations influence women's IT career decisions. The framework is used to support the theoretical argument that women exhibit a range of decisions regarding career and parenthood: the non-parent, the working parent, the back-on-track parent, and the off-the-track parent. These findings illustrate an identifiable theme that crosses geographical regions and timeframes; societal messages are complex and difficult to digest and are processed in different ways by different women, yet they contribute to the decisions women make about their professional and personal lives.
Patients with multiple myeloma treated with thalidomide: evaluation of clinical parameters, cytokines,angiogenic markers, mast cells and marrow CD57+ cytotoxic T cells as predictors of outcome.

BACKGROUND AND OBJECTIVES In vitro studies suggest that thalidomide has an immunoregulatory role and alters the marrow microenvironment. We assessed laboratory and clinical parameters in patients with myeloma treated with thalidomide as potential prognostic markers and looked for changes with therapy. DESIGN AND METHODS Seventy-five patients with relapsed/refractory myeloma received thalidomide in a phase II trial. Serial samples of platelet-poor plasma and bone marrow were tested for angiogenic cytokines including vascular endothelial growth factor (VEGF), marrow microvessel-density (MVD), mast cells and CD57+ cell expression. The effects of these parameters on response rate (RR), progression-free survival (PFS) and overall survival (OS) were analyzed. RESULTS Elevated baseline VEGF predicted for a superior RR (p=0.018) and PFS. Elevated CD57+ cells also predicted superior PFS (p=0.012). MVD did not predict for RR, PFS or OS, but MVD and VEGF fell significantly in responders. Multivariate analysis identified that inferior OS was associated with age >65 years (p=0.017), raised lactate dehydrogenase (p=0.001), raised hepatocyte growth factor levels (p=0.012) and low pre-treatment CD57+ cells (p<0.001). INTERPRETATION AND CONCLUSIONS Our findings support the suggestion that thalidomide has anti-angiogenic and immunomodulatory effects in myeloma. The preferred method for assessing angiogenesis is plasma VEGF levels and the assessment of CD57+ cells for patients with myeloma receiving novel immunomodulatory drugs should be further investigated.
[In-hospital cardiopulmonary resuscitation at Landspitali University Hospital in Reykjavik].

INTRODUCTION Survival after in-hospital cardiac arrest has not been previously reported in Iceland and the purpose of this study was to examine the outcomes of in-hospital resuscitation over a two year period. MATERIAL AND METHODS There are resuscitation teams on each of the two campuses of the University Hospital in Reykjavik. Since the beginning of 2006, the resuscitation teams have compiled their reports in a structured form, Utstein style. RESULTS During 2006 and 2007 resuscitation teams were activated on a total of 311 occasions. Of those, there was need for a full cardiopulmonary resuscitation because of cardiac arrest of in patients in 80 cases (26%). Return of spontaneous circulation was achieved or the patient survived to be transferred to the intensive care unit in 55 (69%) of the 80 cases. Survival to discharge was 33%. Survival to discharge was better if the arrest occurred between 8 AM and 4 PM during daytime (50%), than outside of regular working hours (23%, p=0.02). The survival was better if ventricular tachycardia or fibrillation was the first rhythm encountered (50%) than if the initial rhythm turned out to be asystole or pulseless electrical activity (12%, p=0.002). Those who survived resuscitation were generally younger than those who did not (p=0.002). CONCLUSION The outcomes were similar to those reported at institutions in our neighboring countries. The survival rate was lower if the cardiac arrest occurred outside of regular working hours and if ventricular tachycardia or fibrillation was the first encountered rhythm.
Expression of RGS2, RGS4 and RGS7 in the developing postnatal brain

The abundant expression of RGS (regulator of G‐protein signalling) proteins in neurons, together with their modulatory function on G‐protein‐dependent neurotransmission, provides the basis for cellular adaptation to sensory inputs. To identify the molecular mechanism involved in the sensory experience‐induced neural development, we performed a systematic survey of the localization of mRNAs encoding three subtypes of the RGSs (RGS2, RGS4 and RGS7) in developing rat brains by in situ hybridization through postnatal day 2 (P2), P10 and P18 to adult. The most dramatic changes of expression patterns were observed in the discrete neuronal cell layers of the cerebral neocortex (for RGS2 and 4), the hippocampus (for RGS2, 4 and 7), the thalamus (for RGS4) and the cerebellum (for RGS2 and 7). In the neocortex, RGS2 mRNA was enriched in the superficial cortical plate at P2, in contrast to RGS4, which was enriched in more mature neurons of the deeper layer V and VI. In the hippocampus, the neuronal cell layer‐specific expression pattern of RGS2 developed from P2 to P18. RGS4 expression was temporarily confined to the CA pyramidal cell layer and not detectable in the dentate gyrus at P10 and P18. Similarly, a high level of expression of RGS7 was observed in the CA area, but not in the dentate gyrus at P2 and P10. In the cerebellum, the maturation of laminar expression patterns for the three RGSs correlated with neuronal maturation and synaptogenesis at P18. The most characteristic temporal pattern among the three RGSs was observed for RGS4 mRNA, which was highly enriched in the thalamocortical regions. The peaks of RGS4 expression were seen in the following regions with distinct onset and duration: the neocortex (from P2 onward), the hippocampus (P10 and P18) and the thalamus (from P18 onward). The divergent temporal and spatial expression of RGS subtypes and their dynamic control in the cortex, the hippocampus and the thalamus suggest that the RGS family could play multiple distinct roles in experience‐dependent brain development.
Forecasting Corn Futures Volatility in the Presence of Long Memory, Seasonality and Structural Change

Price volatility in the corn market has changed considerably globalization and stronger linkages to the energy complex. Using data from January 1989 through December 2009, we estimate and forecast the volatility in the corn market using futures daily prices. Estimates in a Fractional Integrated GARCH framework identify the importance of long memory, seasonality, and structural change. Recursively generated forecasts for up to 40-day horizons starting in January 2005 highlight the importance of seasonality, and long memory specifications which perform well at more distant horizons particularly with rising volatility. The forecast benefits of allowing for structural change in an adaptive framework are more difficult to identify except at more distant horizons after a large downturn in volatility.
THE EVOLUTION OF THEORIES OF INTERACTIVE BEHAVIOR

S peculation about the role and impact of nonverbal behavior in the human condition has been present for centuries in philosophy, science, and literature (see Knapp, this volume). Nevertheless, the development of systematic and focused empirical research on nonverbal behavior is a relatively recent phenomenon, growing rapidly from the late 1950s through the present day. Although the vast majority of this work consists of empirical research, theoretical scholarship has also been important, not only in developing a broader understanding of nonverbal communication but also in shaping subsequent empirical work. This chapter focuses on some of this theoretical development. In particular, I discuss theories of interactional nonverbal behavior (i.e., patterned cues in face-to-face contexts). Although nonverbal communication operates in a wide variety of contexts, it is especially important in face-to-face interactions. In such interactions, patterns of behavior are “negotiated” subtly and move typically toward some degree of stability. Partners’ behavior patterns might converge and be similar in form, or they might diverge and be dissimilar. Simultaneously, interactants make a wide variety of judgments about their partners and the interaction. So, how do we explain the complex 2
