Effects of a medical intensivist on patient care in a community teaching hospital.

OBJECTIVE To determine the effect of adding a trained intensivist on patient care and educational outcomes in a community teaching hospital. MATERIAL AND METHODS We retrospectively reviewed outcomes for patients admitted to the medical intensive-care unit (MICU) of a 270-bed community teaching hospital between July 1992 and June 1994. Mortality rates and durations of stay were determined for the year before (BD, 1992 through 1993) and the first year after (AD, 1993 through 1994) introduction of a full-time director of critical care. Performance of resident trainees on a standardized critical-care examination was measured for the same periods. RESULTS Overall, 459 patients in the BD period were compared with 471 patients in the AD period. The mix of cases and severity of illness (acute physiology and chronic health evaluation or APACHE II scores) on admission were similar for the BD and AD periods. MICU mortality decreased from 20.9% during the BD to 14.9% during the AD period (P = 0.02), and in-hospital mortality decreased from 34.0% to 24.6% (P = 0.002). Disease-specific mortalities were lower during the AD period for most categories of illness. Detailed analysis of a subgroup of patients (those with pneumonia) demonstrated no differences in distribution of patients by gender, race, or acuity of illness (APACHE II scores). The mortality rate due to pneumonia decreased from 46% during the BD period to 31% during the AD period. This decrease was consistent across categories of APACHE II scores. From BD to AD periods, mean durations of total hospital stay decreased from 22.6 +/- 1.4 days to 17.7 +/- 1.0 days, and mean MICU stay decreased from 5.0 +/- 0.3 days to 3.9 +/- 0.3 days (P < 0.05). Critical-care in-service examination scores for 22 residents increased from 53.8 +/- 1.7% to 67.5 +/- 2.2% (P < 0.01), and AD scores were significantly higher than BD scores for residents at similar levels of training. CONCLUSION Addition of a medical intensivist was temporally associated with improved clinical and educational outcomes in our community teaching hospital.
Effects of masculine identity and gender role stress on aggression in men.

IN MEN by AMY COHN (Under the Direction of Amos Zeichner, Ph.D.) ABSTRACT Predominant theories posit that the association between masculine identity and aggression is moderated by the degree to which a man experiences cognitive stress when adhering to masculine norms; referred to as gender role stress. This study sought to examine whether masculine identity predicts aggressive behavior (under laboratory conditions) and whether this relationship is moderated by gender role stress. Seventy-five undergraduate males participated in a competitive reaction-time task whereby they were given the choice to shock or refrain from shocking an ‘ostensible’ opponent. Analyses revealed a significant moderating effect of gender role stress on the relationship between identity and aggression as well as significant main effects for identity and gender role stress. Findings are discussed as having implications for understanding the influence of intra-individual factors in the initiation and maintenance of aggressive behavior as well as the contribution of gender role socialization to understanding aggression.
Tracking the Response of Natural Killer T Cells to a Glycolipid Antigen Using Cd1d Tetramers

A major group of natural killer (NK) T cells express an invariant Vα14+ T cell receptor (TCR) specific for the lipoglycan α-galactosylceramide (α-GalCer), which is presented by CD1d. These cells may have an important immune regulatory function, but an understanding of their biology has been hampered by the lack of suitable reagents for tracking them in vivo. Here we show that tetramers of mouse CD1d loaded with α-GalCer are a sensitive and highly specific reagent for identifying Vα14+ NK T cells. Using these tetramers, we find that α-GalCer–specific T lymphocytes are more widely distributed than was previously appreciated, with populations of largely NK1.1− but tetramer-binding T cells present in the lymph nodes and the intestine. Injection of α-GalCer leads to the production of both interferon γ and interleukin 4 by nearly all NK T cells in the liver and the majority of the spleen within 2 h. These cells mostly disappear by 5 h, and they do not reappear after 1 wk. Curiously, tetramer-positive thymocytes do not rapidly synthesize cytokines, nor do they undergo decreases in cell number after lipid antigen stimulation, although they express equivalent TCR levels. In summary, the data presented here demonstrate that α-GalCer–specific NK T cells undergo a unique and highly compartmentalized response to antigenic stimulation.
On joint coding for watermarking and encryption

In continuation of earlier work, where the problem of joint information embedding and lossless compression (of the composite signal) was studied in the absence and in the presence of attacks, here we consider the additional ingredient of protecting the secrecy of the watermark against an unauthorized party, which has no access to a secret key shared by the legitimate parties. In other words, we study the problem of joint coding for three objectives: information embedding, compression, and encryption. Our main result is a coding theorem that provides a single-letter characterization of the best achievable tradeoffs among the following parameters: the distortion between the composite signal and the covertext, the distortion in reconstructing the watermark by the legitimate receiver, the compressibility of the composite signal (with and without the key), and the equivocation of the watermark, as well as its reconstructed version, given the composite signal. In the attack-free case, if the key is independent of the covertext, this coding theorem gives rise to a threefold separation principle that tells that asymptotically, for long block codes, no optimality is lost by first applying a rate-distortion code to the watermark source, then encrypting the compressed codeword, and finally, embedding it into the covertext using a previously proposed embedding scheme. In the more general case, however, this separation principle is no longer valid, as the key plays an additional role of side information used by the embedding unit
The Program and Treatment Effect of Summer Jobs on Girls’ Post-Schooling Incomes

Background: Public programs offering summer jobs to smooth the transition from school to work is commonplace. However, the empirical support for summer jobs is limited. This article exploits the availability of registered individual information and random allocation to summer jobs to provide empirical evidence on this issue. Objectives: To identify the effect of summer job programs on the post-schooling incomes of the intended participants. Also to identify the effect of sophomore girls’ high school work experience on their post-schooling incomes. Research Design: In this article, 1,447 sophomore girls from 1997 to 2003 are followed 5–12 years after graduation. They all applied to Falun municipality’s (Sweden) summer job program, and about 25% of them were randomly allotted a job. The random allocation to a summer job is used to identify the causal effect of sophomore girls’ high school income on their post-schooling incomes. Subjects: All the 1,447 sophomore girls who applied to Falun municipality’s summer job program during 1997–2003. Measures: Annual post-schooling income is used as an outcome measure. The work experience of girls in high school is also measured in terms of total income while in high school. Results: The program led to a substantially larger accumulation of income during high school as well as 19% higher post-schooling incomes. The high school income led to a post-schooling income elasticity of 0.37 which is, however, potentially heterogeneous with regard to academic ability. Conclusions: Both the program effect and the causal effect of high school income on post-schooling incomes were substantial and statistically significant.
Laparoscopic Surgery for Solid Pseudopapillary Tumor of the Pancreas

Background and Objectives: Solid pseudopapillary tumors of the pancreas are rare and occur most frequently in young women. They have an uncertain pathogenesis and unclear clinical behavior. Our aim was to evaluate the clinical presentation of solid pseudopapillary tumors and assess the efficacy of treatment with minimally invasive surgery. Methods: From March 1997 to February 2011, 13 of 273 patients who underwent laparoscopic procedures on the pancreas were found to have solid pseudopapillary tumors. There were 12 female patients and 1 male patient. The median age was 21 years (range, 15–77 years). Abdominal pain was the most common presenting symptom (n = 9). Tumors were incidentally found in 3 patients on computed tomography scans obtained for other reasons. Results: Enucleation of the tumor was performed in 4 patients, including 3 in whom the tumor was located in the head of the pancreas. Eight patients underwent distal pancreatectomy with splenectomy, whereas spleen-preserving distal pancreatectomy was performed in one case. The median tumor size was 6 cm (range, 1.5–11 cm), the median operative time was 197 minutes (range, 68–320 minutes), and the median blood loss was 50 mL (range, <50–750 mL). Distal resections were performed with a linear stapler. Four patients had postoperative complications. The median length of hospital stay was 5 days (range, 2–12 days). During a median follow-up period of 11 months (range, 3–121 months), no local recurrences or distant metastases were found. Conclusion: Laparoscopic resections and enucleations of solid pseudopapillary tumors of the pancreas can be performed safely and with adequate resection margins even if the tumors are located in the head of the organ.
Protecting Against Network Infections: A Game Theoretic Perspective

Security breaches and attacks are critical problems in today’s networking. A key-point is that the security of each host depends not only on the protection strategies it chooses to adopt but also on those chosen by other hosts in the network. The spread of Internet worms and viruses is only one example. This class of problems has two aspects. First, it deals with epidemic processes, and as such calls for the employment of epidemic theory. Second, the distributed and autonomous nature of decision-making in major classes of networks (e.g., P2P, adhoc, and most notably the Internet) call for the employment of game theoretical approaches. Accordingly, we propose a unified framework that combines the N-intertwined, SIS epidemic model with a noncooperative game model. We determine the existence of a Nash equilibrium of the respective game and characterize its properties. We show that its quality, in terms of overall network security, largely depends on the underlying topology. We then provide a bound on the level of system inefficiency due to the noncooperative behavior, namely, the “price of anarchy” of the game. We observe that the price of anarchy may be prohibitively high, hence we propose a scheme for steering users towards socially efficient behavior.
Learning Semantic Hierarchies via Word Embeddings

Semantic hierarchy construction aims to build structures of concepts linked by hypernym‐hyponym (“is-a”) relations. A major challenge for this task is the automatic discovery of such relations. This paper proposes a novel and effective method for the construction of semantic hierarchies based on word embeddings, which can be used to measure the semantic relationship between words. We identify whether a candidate word pair has hypernym‐hyponym relation by using the word-embedding-based semantic projections between words and their hypernyms. Our result, an F-score of 73.74%, outperforms the state-of-theart methods on a manually labeled test dataset. Moreover, combining our method with a previous manually-built hierarchy extension method can further improve Fscore to 80.29%.
Iron Isotope Fractionation During Magmatic Differentiation in Kilauea Iki Lava Lake

Magmatic differentiation helps produce the chemical and petrographic diversity of terrestrial rocks. The extent to which magmatic differentiation fractionates nonradiogenic isotopes is uncertain for some elements. We report analyses of iron isotopes in basalts from Kilauea Iki lava lake, Hawaii. The iron isotopic compositions (56Fe/54Fe) of late-stagemeltveins are 0.2 permil (‰) greater than values for olivine cumulates. Olivine phenocrysts are up to 1.2‰ lighter than those of whole rocks. These results demonstrate that iron isotopes fractionate during magmatic differentiation at both whole-rock and crystal scales. This characteristic of iron relative to the characteristics of magnesium and lithium, for which no fractionation has been found, may be related to its complex redox chemistry in magmatic systems and makes iron a potential tool for studying planetary differentiation.
The carboxy termini of Sir4 and Rap1 affect Sir3 localization: evidence for a multicomponent complex required for yeast telomeric silencing

The Silent Information Regulatory proteins, Sir3 and Sir4, and the telomeric repeat-binding protein RAP1 are required for the chromatin- mediated gene repression observed at yeast telomeric regions. All three proteins are localized by immunofluorescence staining to foci near the nuclear periphery suggesting a relationship between subnuclear localization and silencing. We present several lines of immunological and biochemical evidence that Sir3, Sir4, and RAP1 interact in intact yeast cells. First, immunolocalization of Sir3 to foci at the yeast nuclear periphery is lost in rap1 mutants carrying deletions for either the terminal 28 or 165 amino acids of RAP1. Second, the perinuclear localization of both Sir3 and RAP1 is disrupted by overproduction of the COOH terminus of Sir4. Third, overproduction of the Sir4 COOH terminus alters the solubility properties of both Sir3 and full-length Sir4. Finally, we demonstrate that RAP1 and Sir4 coprecipitate in immune complexes using either anti-RAP1 or anti-Sir4 antibodies. We propose that the integrity of a tertiary complex between Sir4, Sir3, and RAP1 is involved in both the maintenance of telomeric repression and the clustering of telomeres in foci near the nuclear periphery.
Detection of multiple human location and direction by integrating different kinds of sensors

As ubiquitous services become available, information on human location and direction have so important that many detection methods have been proposed. However, a lot of them generate electromagnetic waves or light rays. They are unsuited for use in detection of children's location because parents are wary of health damage caused by radiated electromagnetic waves. The accuracy of a lot of methods which doesn't generate electromagnetic waves is not always high indoors. In this paper, we propose a detection method of indoor multiple human location and direction by using a stereovision camera and direction detection sensors. With a stereovision camera, it is possible to detect human location with high accuracy, but individuals cannot be identified. Direction detection sensors make it possible to identify an individual wearing them. By integrating these sensing devices based on direction information, detection of location and direction become possible with high accuracy. Moreover, with this method it is possible to identify an individual. We built a prototype and conducted an evaluation experiment. We conducted the experiment in a room divided by a ferroconcrete wall. We conducted a total of 10 experiments, changing the number of subjects. The experimental evaluation result shows the average error of location was 0.11[m] and the average error of direction was 0.39[rad]. The success rate of identifying an individual was 90[%].
SERRE’S CONJECTURES

The goal of these notes is to provide an introduction to Serre’s conjecture concerning odd irreducible 2dimensional mod p Galois representations. The primary reference is Serre’s excellent paper [23]. We follow Serre’s suggestion in that paper and work systematically with modular forms in the sense of Katz, and must therefore modify Serre’s definitions of the weight of a Galois representation as in [9]. The first part of these notes gives an overview of the algebro-geometric theory of modular forms: such a viewpoint is essential in order to prove results later on down the road. Next, we explain the precise form of Serre’s conjecture specifying the level, weight, and character of an odd irreducible mod p Galois representation and motivate this recipe with the deep theorems of Deligne, Fontaine, Carayol and others describing the existence and properties of mod p representations associated to modular forms. Finally, we give evidence—both theoretical and computational–for Serre’s conjecture. In particular, we treat the general case of icosahedral mod 2 Galois representations, and correct several mistakes in Mestre’s original development [19] of these examples.
OpenFace: An open source facial behavior analysis toolkit

Over the past few years, there has been an increased interest in automatic facial behavior analysis and understanding. We present OpenFace - an open source tool intended for computer vision and machine learning researchers, affective computing community and people interested in building interactive applications based on facial behavior analysis. OpenFace is the first open source tool capable of facial landmark detection, head pose estimation, facial action unit recognition, and eye-gaze estimation. The computer vision algorithms which represent the core of OpenFace demonstrate state-of-the-art results in all of the above mentioned tasks. Furthermore, our tool is capable of real-time performance and is able to run from a simple webcam without any specialist hardware. Finally, OpenFace allows for easy integration with other applications and devices through a lightweight messaging system.
The Possible Role of Transplacentally-Acquired Antibodies to Infectious Agents, With Molecular Mimicry to Nervous System Sialic Acid Epitopes, as Causes of Neuromental Disorders: Prevention and Vaccine Implications

Proof of causality of most neuromental disorders (NMD's) is largely unavailable. Lessons from four-decade investigations of the epidemiology, immunology, pathogenesis, prevention and therapy of perinatal infectious agents, which invade directly the nervous system, have led us to propose a new indirect effect hypothesis: maternal transplacentally-acquired antibodies, to agents with epitope molecular mimicry with the developing nervous system, can cross the fetus/infant's blood–nervous system barriers to cause NMD's, clinically manifest years later. Further rationale is provided by relevant evolutionary/developmental (EVO–DEVO) considerations—applicable also to some vaccines. The hypothesis is being tested in: (a) older pregnancy studies with available maternal and newborn sera, and follow-up of the progeny for NMD's; and (b) NMD registry individuals linked to their stored newborn blood spots. Preliminary results support a possible role for schizophrenia of high-tittered antibodies to some agents (toxoplasma, influenza and herpes simplex type 2 virus). A model that includes likely genetic and postnatal influences is schematized and a list of putative agents and factors, based on varying rationales, is tabulated. In case pilot studies are confirmed, the identified agent(s) and antibodies would need to be tested in new prospectively enrolled pregnant women, so as to establish further risk factors leading to possible preventive modalities.
An Idealized Model Study of the Mass and Heat Transports between the Subpolar and Subtropical Gyres

Abstract The response of an ocean model of the subtropical and subpolar gyres to idealized surface forcing anomalies that mimic the thermal and mechanical forcing associated with the North Atlantic Oscillation (NAO) is analyzed. Emphasis is given on the subpolar gyre and the mechanisms that drive the mass and heat exchanges between the two gyres. First, steady anomalies are applied. Surface heat flux anomalies induce density gradient anomalies at depth, which drive current anomalies reinforcing the north-eastward mean current separating the two gyres. The northward heat transport of these anomalous currents is 10 times stronger than that associated with the transport of temperature anomalies by the mean current. The heat transport anomalies between the two gyres balances the prescribed surface heat flux after 6–7 yr. A similar mechanism is at work when a decadal harmonic forcing is considered, but the lag is shortened to 3–4 yr. The model response to a wind stress curl anomaly shows a similar behavior to .
Assessing Different Drivers of the GreatModeration in the U.S

This paper employs a calibrated new-Keynesian DSGE model to assess the relative importance of two different, potentially important drivers of the Great Moderation in the U.S., namely 'good policy' vs. 'good luck'. The calibrated model is capable to replicate the actual standard deviations of inflation and output. Factual and counterfactual simulations are run in order to gauge the relative importance of the systematic monetary policy vs. the stochastic shocks hitting the economic system in shaping some macroeconomic volatilities. Importantly, under the bad policy scenario sunspots may influence the equilibrium values of the macroeconomic variables of interest, and distortions in the transmission mechanism going from the structural shocks to the variables of interest are allowed for. Our findings support the relevance of both drivers in causing inflation volatility. By contrast, output volatility can hardly be explained by a monetary policy switch like the one occurred in the U.S. at the end of the '70s.
Weight Distributions of Regular Low-Density Parity-Check Codes Over Finite Fields

The average weight distribution of a regular low-density parity-check (LDPC) code ensemble over a finite field is thoroughly analyzed. In particular, a precise asymptotic approximation of the average weight distribution is derived for the small-weight case, and a series of fundamental qualitative properties of the asymptotic growth rate of the average weight distribution are proved. Based on this analysis, a general result, including all previous results as special cases, is established for the minimum distance of individual codes in a regular LDPC code ensemble.
Giant Lipomatosis of the Sciatic Nerve: Unique Magnetic Resonance Imaging Findings

Lipomatosis of the nerve, also known as fibrolipomatous hamartoma, is characterized by the infiltration of the nerve by fibro-fatty tissue. The affected nerve becomes thicker, and it simulates a mass lesion. Lipomatosis usually affects the median nerve and lipomatosis of the sciatic nerve is extremely rare. Magnetic resonance imaging (MRI) is the key to diagnosis, and it is usually pathognomonic. In this report, MRI and diffusion-weighted MRI findings of a case of a giant sciatic nerve lipomatosis without macrodactyly are presented. The MRI findings are unique, and awareness of the MRI features of this rare soft tissue mass may prevent unnecessary biopsies and surgeries.
