A First Search for Coincident Gravitational Waves and High Energy Neutrinos Using LIGO, Virgo and ANTARES Data from 2007

We present the results of the first search for gravitational wave bursts associated with high energy neutrinos. Together, these messengers could reveal new, hidden sources that are not observed by conventional photon astronomy, particularly at high energy. Our search uses neutrinos detected by the underwater neutrino telescope ANTARES in its 5 line configuration during the period January - September 2007, which coincided with the fifth and first science runs of LIGO and Virgo, respectively. The LIGO-Virgo data were analysed for candidate gravitational-wave signals coincident in time and direction with the neutrino events. No significant coincident events were observed. We place limits on the density of joint high energy neutrino - gravitational wave emission events in the local universe, and compare them with densities of merger and core-collapse events.
Gay- and Lesbian-Identified Law Enforcement Officers

This qualitative exploration examined how 14 gay- and lesbian-identified law enforcement officers managed career choice, satisfaction, and their intersecting sexual/vocational identities. Participants reported choosing the vocation for much the same reasons as others already mentioned in the literature, including service/duty to community, financial benefits, and family influences. Constraining and facilitating factors were discovered, shedding light on how participants managed their intersecting identities, and their influence on career satisfaction. These factors deepen the understanding of when participants shared their sexual identity with colleagues and to what impact within the career environment. The presence of homophobic microaggressions without institutional support to address the hostile environment significantly hampered job satisfaction and willingness to risk being out at work for some. Implications and suggestions for future research are discussed, including the findings’ usefulness for other quasimilitary vocational settings in the aftermath of the repeal of “Don’t ask, don’t tell” legislation in the military.
On the Performance of Cooperative Amplify-and-Forward Relay Networks

This paper provides a general analysis of cooperative amplify-and-forward relay networks and gives a unified and comparative view of various proposed systems. The studied cooperative relay networks offer spatial diversity gains that conventional multi-antenna systems often fail to achieve due to limitations of the feasible number of antennas per terminal and correlated propagation. We first present a general analysis for the case of multiple antennas per node, which is subsequently used to investigate the relative attractiveness of cooperative schemes for various parameters that include SNR, spectral efficiency, and spatial correlation. We conclude that such virtual antenna arrays are an attractive option to overcome the drawbacks of conventional relaying systems.
Job Stressors as predictor of Counterproductive work behaviour in Indian banking sector

This research study was conducted to understand the cause and effect relationship between Counterproductive Work Behaviour (CWB) and Job stressors among junior managers (scale -1 officer) of Indian public sector banks. Total 300 junior managers (scale -1 officers) were chosen through purposive sampling technique from various Indian public sector banks. Data was collected by questionnaire method and analyzed with structure equation modeling and Karl Pearson correlation. Result of research study reveals sabotage, withdrawal and theft dimensions of counterproductive work behaviour were found positive and significant in correlation with organization constraints, quantitative workload inventory, inter personal conflict at workplace and physical symptoms inventory dimensions of job stressors. Theft dimension of CWB was found positive and significant in correlation with interpersonal conflict at workplace and quantitative workload inventory dimensions of job stressors, among scale-1 officers of Indian Public Sector Banks. No significant correlation was found between theft and physical symptoms inventory, abuse and organization constraint scale, abuse and interpersonal conflict at workplace. Production deviance another dimension of CWB was also found, insignificant in correlation with organization constraint scale, interpersonal conflict at workplace; physical symptoms inventory dimensions of job stressor among scale-1 officers of Indian Public Sector Banks.
On prime factors of integers of the form $ab+1$

1. If n is a positive integer, p is a prime number and k is a non-negative integer with p | n, p n then we write p‖n. For n > 1 let p(n) and P (n) denote the least and greatest prime factor of n, respectively. In the last 15 years many papers have been written on the arithmetical properties of elements of sum sets A + B (defined as the set of the integers of the form a + b with a ∈ A, b ∈ B) where A and B are two “dense” sets of positive integers. In particular, it has been shown that

Examples of the reasons for introducing hydrophobic domains into hydrophilic gels are given; typology of these materials is introduced. Synthesis routes are exemplified and properties of a variety of such hydrogels in relation with their intended applications are described. Future research needs are identified briefly.
Proton (or hydroxide) fluxes and the biphasic osmotic response of human red blood cells

Upon exposure of human red blood cells to hypertonic sucrose, the fluorescence of the potentiometric indicator 3,3'- dipropylthiadicarbocyanine iodide, denoted diS-C3(5), displays a biphasic time course indicating the rapid development of an inside- positive transmembrane voltage, followed by a slow DIDS (4,4'- diisothiocyano-2,2'-disulfonic acid stilbene)-sensitive decline of the voltage. In addition to monitoring membrane potential, proton (or hydroxide) fluxes were measured by a pH stat method, cell volume was monitored by light scattering, and cell electrolytes were measured directly when red cells were shrunken either with hypertonic NaCl or sucrose. Shrinkage by sucrose induced an initial proton efflux (or OH- influx) of 5.5 mu eq/g Hb.min and a Cl shift of 21-31 mu eq/g Hb in 15 min. Upon shrinkage with hypertonic NaCl, the cells are initially close to Donnan equilibrium and exhibit no detectable shift of Cl or protons. Experiments with the carbonic anhydrase inhibitor ethoxzolamide demonstrate that for red cell suspensions exposed to air and shrunken with sucrose, proton fluxes mediated by the Jacobs-Stewart cycle contribute to dissipation of the increased outward Cl concentration gradient. With maximally inhibitory concentrations of ethoxzolamide, a residual proton efflux of 2 mu eq/g Hb.min is insensitive to manipulation of the membrane potential with valinomycin, but is completely inhibited by DIDS. The ethoxzolamide-insensitive apparent proton efflux may be driven against the electrochemical gradient, and is thus consistent with HCl cotransport (or Cl/OH exchange). The data are consistent with predictions of equations describing nonideal osmotic and ionic equilibria of human red blood cells. Thus osmotic equilibration after shrinkage of human red blood cells by hypertonic sucrose occurs in two time-resolved steps: rapid equilibration of water followed by slower equilibration of chloride and protons (or hydroxide). Under our experimental conditions, about two-thirds of the osmotically induced apparent proton efflux is mediated by the Jacobs- Stewart cycle, with the remainder being consistent with mediation via DIDS-sensitive HCl cotransport (or Cl/OH exchange).
Isolation of plasma membranes from corn roots by sucrose density gradient centrifugation: an anomalous effect of ficoll.

An investigation was conducted into the isolation of plasma membrane vesicles from primary roots of corn (Zea mays L., WF9 x M14) by sucrose density gradient centrifugation. Identification of plasma membranes in cell fractions was by specific staining with the periodic-chromic-phosphotungstic acid procedure. Plasma membrane vesicles were rich in K(+)-stimulated ATPase activity at pH 6.5, and equilibrated in linear gradients of sucrose at a peak density of about 1.165 g/cc. It was necessary to remove mitochondria (equilibrium density of 1.18 g/cc) from the homogenate before density gradient centrifugation to minimize mitochondrial contamination of the plasma membrane fraction. Endoplasmic reticulum (NADH-cytochrome c reductase) and Golgi apparatus (latent IDPase) had equilibrium densities in sucrose of about 1.10 g/cc and 1.12 to 1.15 g/cc, respectively. A correlation (r = 0.975) was observed between K(+)-stimulated ATPase activity at pH 6.5 and the content of plasma membranes in various cell fractions. ATPase activity at pH 9 and cytochrome c oxidase activity were also correlated.A major peak of ATPase activity at pH 6.5 was observed at low density in Ficoll after nonequilibrium centrifugation in a combination Ficoll-sucrose gradient. Twenty to forty percent of the vesicles in this ATPase fraction stained positively for plasma membranes, and with equilibrium centrifugation the major portion of the ATPase activity shifted to densities in sucrose which were characteristic of plasma membranes. All major vesicular ATPase activities observed in Ficoll or sucrose contained substantial amounts of plasma membranes. For unknown reasons, mitochondria and plasma membranes equilibrated over a broader density range and at lower peak densities in sucrose as a result of equilibrium centrifugation through Ficoll.
Internal Evaluation Measures as Proxies for External Indices in Clustering Gene Expression Data

Several external indices that use information not present in the dataset were shown to be useful for evaluation of representative based clustering algorithms. However, such supervised measures are not directly useful for construction of better clustering algorithms when class labels are not provided. We propose a method for identifying internal cluster evaluation measures that use only information present in the dataset and are related to given external indices. We utilize these internal measures for the construction of representative based clustering algorithms. Both identification and utilization steps of the proposed method are enabled by use of a component-based clustering algorithm design. Experiments on 432 algorithms using gene expression data sets provide evidence that some internal measures could be used as surrogates for external indices proposed in the literature. Moreover, the obtained results suggest that internal measures correlated to selected external indices can guide the algorithms toward significantly better cluster models.
Median aperture of the fourth ventricle revisited.

BACKGROUND The median aperture of Magendie is the largest of three openings of the fourth ventricle and thus it forms the main path for the outflow of the cerebrospinal fluid from the ventricle. The Magendie aperture connects the fourth ventricle with the cisterna magna and makes a natural corridor for neurosurgical approach and inspection of the ventricle and its floor. The purpose of this study was to give a contemporary anatomical view of this structure in the context of historical data. MATERIAL AND METHODS The Magendie foramen was studied in 30 fixed specimens of human brainstems with cerebella. The microdissection technique was used. Measurements were taken with a microscope ocular ruler. RESULTS The aperture is limited by the following structures: obex and gracile tubercles inferiorly, and tela choroidea with choroid plexus superolaterally. Obex tubercles usually have the form of a piece of neural tissue bridging two halves of the brainstem above the entrance to the central canal. Gracile tubercles together are 8.15 mm wide and the maximal width of the foramen is 6.53 mm. Tela choroidea attaches laterally at both sides to the inferior medullary velum. In most cases the right and left choroid plexus are connected to each other with a triangular membrane of tela choroidea, which protrudes through the median foramen and attaches to the vermis at a highly variable level. CONCLUSIONS We hope that the presented description of anatomical relations around the Magendie aperture, with its new measurements, will be helpful for those operating in the area and will explain some of the inaccuracies found in literature.
Reframing the Embodied Consumer As Cyborg a Posthumanist Epistemology of Consumption

The two-fold purpose of this research is to introduce a posthumanist epistemology of technology consumption and to illustrate the usefulness of this epistemology in the study of consumption as a whole. Combining recent Anglo-American theories of consumer behavior and European systems theory, we first introduce the tetralemma of the system, an analytical framework for the systemic structuration of consumer behavior, which is then used to explore and develop three posthumanist systems on the rise and of interest in the marketplace matrix: (1) cyborg consumers (2) brand systems and (3) protest systems. The cyborg is the prototypical posthumanist consumer, a cybernetic organism that signifies the symbiosis between animal and machine, but also reflects the transformative union between economic priority and insatiable desire, living being and observing system. A brand system embeds consumers’ and marketers’ brand related social communication to establish control over consumption. A protest system is concerned with the ongoing social process of ensuring outsider status from the market dominated social environment through consumption. Finally, we conclude that our posthumanist epistemology of consumption and the notion of systems provide important new insights into the posthumanist understanding of the consumer as well as the cultural structuring of posthuman consumer culture.
Diffusion-Weighted MRI as a Biomarker of Tumor Radiation Treatment Response Heterogeneity: A Comparative Study of Whole-Volume Histogram Analysis versus Voxel-Based Functional Diffusion Map Analysis.

RATIONALE Treatment of glioblastoma (GBM) remains challenging due in part to its histologic intratumoral heterogeneity that contributes to its overall poor treatment response. Our goal was to evaluate a voxel-based biomarker, the functional diffusion map (fDM), as an imaging biomarker to detect heterogeneity of tumor response in a radiation dose escalation protocol using a genetically engineered murine GBM model. EXPERIMENTAL DESIGN Twenty-four genetically engineered murine GBM models [Ink4a-Arf(-/-)/Pten(loxp/loxp)/Ntv-a RCAS/PDGF(+)/Cre(+)] were randomized in four treatment groups (n = 6 per group) consisting of daily doses of 0, 1, 2, and 4 Gy delivered for 5 days. Contrast-enhanced T1-weighted and diffusion-weighted magnetic resonance imaging (MRI) scans were acquired for tumor delineation and quantification of apparent diffusion coefficient (ADC) maps, respectively. MRI experiments were performed daily for a week and every 2 days thereafter. For each animal, the area under the curve (AUC) of the percentage change of the ADC (AUCADC) and that of the increase in fDM values (AUCfDM+) were determined within the first 5 days following therapy initiation. RESULTS Animal survival increased with increasing radiation dose. Treatment induced a dose-dependent increase in tumor ADC values. The strongest correlation between survival and ADC measurements was observed using the AUCfDM+ metric (R (2) = 0.88). CONCLUSION This study showed that the efficacy of a voxel-based imaging biomarker (fDM) was able to detect spatially varying changes in tumors, which were determined to be a more sensitive predictor of overall response versus whole-volume tumor measurements (AUCADC). Finally, fDM provided for visualization of treatment-associated spatial heterogeneity within the tumor.

Effects of Surgical Lengthening of the Hamstrings Without a Concomitant Distal Rectus Femoris Transfer in Ambulant Patients With Cerebral Palsy

Eighteen ambulant patients (32 legs) who had undergone fractional lengthening of the medial and lateral hamstrings without rectus femoris transfer underwent pre- and postoperative gait analysis. A significant increase in the amount of knee extension and a decrease in the amount of peak knee flexion in swing were observed. This decrease in knee flexion signified a change towards more normal speed-related values. Dorsiflexion at initial contact decreased significantly for patients who did not undergo a gastrocnemius lengthening (n = 24). Absolute cadence was significantly lower after surgery, but the change in dimensionless cadence was not significantly different. This difference in the outcome between dimensionless and absolute stride parameters can be attributed to the increase in body height after surgery. The clinical significance of these findings is that it is important to recognize that postoperative effects of surgery on gait in children may, in part, be explained by changes in height and not surgery alone.
Concurrent Optical Imaging Spectroscopy and Laser-Doppler Flowmetry: The Relationship between Blood Flow, Oxygenation, and Volume in Rodent Barrel Cortex

Functional magnetic resonance imaging (fMRI) is based on the coupling between neural activity and changes in the concentration of the endogenous paramagnetic contrast agent deoxygenated hemoglobin. Changes in the blood oxygen level-dependent (BOLD) signal result from a complex interplay of blood volume, flow, and oxygen consumption. Optical imaging spectroscopy (OIS) has been used to measure changes in blood volume and saturation in response to increased neural activity, while laser Doppler Flowmetry (LDF) can be used to measure flow changes and is now commonplace in neurovascular research. Here, we use concurrent OIS and LDF to examine the hemodynamic response in rodent barrel cortex using electrical stimulation of the whisker pad at varying intensities. Spectroscopic analysis showed that stimulation produced a biphasic early increase in deoxygenated hemoglobin (Hbr), followed by a decrease below baseline, reaching minima at approximately 3.7 s. There was no evidence for a corresponding early decrease in oxygenated hemoglobin (HbO(2)), which simply increased after stimulation, reaching maximum at approximately 3.2 s. The time courses of changes in blood volume (CBV) and blood flow (CBF) were similar. Both increased within a second of stimulation onset and peaked at approximately 2.7 s, after which CBV returned to baseline at a slower rate than CBF. The changes in Hbr, Hbt, and CBF were used to estimate changes in oxygen consumption (CMRO(2)), which increased within a second of stimulation and peaked approximately 2.2 s after stimulus onset. Analysis of the relative magnitudes of CBV and CBF indicates that the fractional changes of CBV could be simply scaled to match those of CBF. We found the relationship to be well approximated by CBV = CBF(0.29). A similar relationship was found using the response to elevated fraction of inspired carbon dioxide (FICO(2)).
Impact of combined precut techniques on selective biliary cannulation.

INTRODUCTION simple biliary cannulation techniques obtain a success rate of 80-95%. Advanced precut techniques are not immediately successful in 10-40% of cases. Between extreme options such as a second attempt a few days later or an immediate attempt by the transparietal route, an alternative precut technique may be used as a rescue strategy for the initially failed procedure. The purpose of this study was to assess the efficacy and safety of the combined use of two precut techniques when immediate biliary access is not granted by an initial procedure. PATIENTS AND METHOD a retrospective analysis of a personal series of precut (needle-knife and transpancreatic) sphincterotomies, both alone and in combination. RESULTS five hundred sixty nine ERCPs (endoscopic retrograde cholangio-pancreatography) met the inclusion criteria for the analysis. Simple cannulation was obtained in 444 (78%) of them. In all, 119 (21%) precuts were attempted and 110 (92.4%) were successful, which raised the overall cannulation rate to 97.4%. Ninety-five (80%) precuts were successful with the initial technique. Rescue with the alternative technique was attempted for 20 failures with a successful outcome in 15, which raised the overall success rate to 92%. The combination of needle-knife precut plus transpancreatic precut raised the success rate from 87% to 94%. The combination of transpancreatic precut plus needle-knife precut raised the success rate from 70% to 90%. Among all 96 patients with available follow-up data, 17 (18%) complications were recorded: 9 bleeding episodes, 4 pancreatitis cases, and 4 retroperitoneal perforations. No mortality was recorded. CONCLUSIONS a combination of precut techniques is effective for biliary cannulation when simple cannulation and initial precut approaches fail. The safety profile differs from that in the delayed strategy, hence both should be considered alternatives, their use depending on the technical and clinical conditions prevailing for each patient, as well as endoscopist experience.
Perception of age and creativity in work context

As the workforce ages it becomes important to examine if there is misperception of creativity and age in work contexts. A laboratory experiment examined perceptions of the creativity of a team with both young and old workers and of a team composed entirely of young workers. Scripted videos portrayed such teams engaged in designing an outdoor advertising campaign. Altogether, 220 participants were randomly assigned to watch one of the video clips and complete a structured questionnaire. No significant differences were observed in the perceptions of the two teams’ performance or of the quality of the resulting advertising proposal. In general, there was also no significant difference in the individual characteristics attributed to the four characters on the teams. However, participants aged 35 or above evaluated both teams and all four characters more favorably than participants aged 20 to 34.
