Low-density linear IED schemes for lossless source coding with decoder only side information

In this paper we investigate the performance of linear interactive encoding and decoding (IED) for lossless source coding with decoder only side information. Assume that the source alphabet chi is a finite field and that the side information alphabet is finite. It is shown that there exist universal linear IED schemes which are asymptotically optimal for any stationary, ergodic source-side information pair. Our analysis of low-density IED schemes further reveals that as long as isin<sub>n</sub>p<sub>n</sub> <sup>*</sup> = Omega(log n/n), where isin<sub>n</sub> and p<sub>n</sub> <sup>*</sup> are real numbers, one can always construct a sequence of universal linear IED schemes {I<sub>n</sub>} such that the average density of the parity check matrices associated with I<sub>n</sub> is concentrated around (|chi|-1)p<sub>n</sub> <sup>*</sup>, and the resulting symbol error probability is upper bounded by isin<sub>n</sub> + o(isin<sub>n</sub>).

Improved rendering algorithm of caustics and shadows based on caustic volume

For transparent objects modeled by triangular mesh, we present an improved rendering algorithm for caustics and shadows based on caustic volume method. Traditional caustic volume algorithm generates caustic volumes for triangles that can be viewed from light source position in accordance with geometrical optics formula. But it only applies to large-scale water. Using subdivision for triangles, our improved algorithm increases the applicability of caustic volume method. Besides, based on the observation that caustic volumes have covered both caustics and shadows region, this algorithm estimates the radiation of caustics and shadows in similar way and generates high-quality caustics and shadows for transparent objects simultaneously.
Distributed run-time resource management for malleable applications on many-core platforms

Todays prevalent solutions for modern embedded systems and general computing employ many processing units connected by an on-chip network leaving behind complex superscalar architectures In this paper, we couple the concept of distributed computing with parallel applications and present a workload-aware distributed run-time framework for malleable applications on many-core platforms. The presented framework is responsible for serving in a distributed way and at run-time, the needs of malleable applications, maximizing resource utilization avoiding dominating effects and taking into account the type of processors supporting platform heterogeneity, while having a small overhead in overall inter-core communication. Our framework has been implemented as part of a C simulator and additionally as a runtime service on the Single-Chip Cloud Computer (SCC), an experimental processor created by Intel Labs, and we compared it against a state-of-art run-time resource manager. Experimental results showed that our framework has on average 70% less messages, 64% smaller message size and 20% application speed-up gain.
INTEGRAL observations of the black hole candidate H 1743 322 in outburst

INTEGRAL made 3 observations in 2003 April of the black hole candidate H 1743-322 during the rising part, and close to the maximum, of an outburst. H 1743-322 was previously observed in outburst in 1977–1978. The source is located in a crowded region of the sky ($l = 357^\circ, \, b = -2^\circ)$ and at least 18 sources are clearly detected in the field of view of the ISGRI gamma-ray imager during a 277 ks exposure. These are well known persistent X-ray binary sources and 3 transient sources in outburst. The combined 5–200 keV JEM-X and SPI spectrum of H 1743-322 is well fit with an absorbed $((2.5 \, ^{+4.3} _{-2.5}) \times 10^{22}$ atom cm -2 ) soft (photon index $2.70 \pm 0.09$) power-law model, consistent with H 1743-322 being in a high/soft state.
Increased Brain Neurotensin and NTSR2 Lead to Weak Nociception in NTSR3/Sortilin Knockout Mice

The neuropeptide neurotensin (NT) elicits numerous pharmacological effects through three different receptors (NTSR1, NTSR2, and NTSR3 also called sortilin). Pharmacological approaches and generation of NTSR1 and NTSR2-deficient mice allowed to determine the NT-induced antipsychotic like behavior, the inhibitory of weak fear memory and the nociceptive signaling in a rat formalin tonic pain model to NTSR1. Conversely, the effects of NT on thermal and tonic nociceptions were mediated by NTSR2. However, the role of NTSR3/sortilin on the neurotensinergic system was not investigated. Here, by using C57Bl/6J mouse model in which the gene coding for NTSR3/sortilin has been inactivated, we observed a modification of the expression of both NTSR2 and NT itself. Quantitative PCR and protein expression using Western blot analyses and AlphaLisa™ technology resulted in the observation that brain NTSR2 as well as brain and blood NT were 2-fold increased in KO mice leading to a resistance of these mice to thermal and chemical pain. These data confirm that NTSR3/sortilin interacts with other NT receptors (i.e., NTSR2) and that its deletion modifies also the affinity of this receptor to NT.
Prehospital thrombolysis in acute stroke

Objective: Beneficial effects of IV tissue plasminogen activator (tPA) in acute ischemic stroke are strongly time-dependent. In the Pre-Hospital Acute Neurological Treatment and Optimization of Medical care in Stroke (PHANTOM-S) study, we undertook stroke treatment using a specialized ambulance, the stroke emergency mobile unit (STEMO), to shorten call-to-treatment time. Methods: The ambulance was staffed with a neurologist, paramedic, and radiographer and equipped with a CT scanner, point-of-care laboratory, and a teleradiology system. It was deployed by the dispatch center whenever a specific emergency call algorithm indicated an acute stroke situation. Study-specific procedures were restricted to patients able to give informed consent. We report feasibility, safety, and duration of procedures regarding prehospital tPA administration. Results: From February 8 to April 30, 2011, 152 subjects were treated in STEMO. Informed consent was given by 77 patients. Forty-five (58%) had an acute ischemic stroke and 23 (51%) of these patients received tPA. The mean call-to-needle time was 62 minutes compared with 98 minutes in 50 consecutive patients treated in 2010. Two (9%) of the tPA-treated patients had a symptomatic intracranial hemorrhage and 1 of these patients (4%) died in hospital. Technical failures encountered were 1 CT dysfunction and 2 delayed CT image transmissions. Conclusions: The data suggest that prehospital stroke care in STEMO is feasible. No safety concerns have been raised so far. This new approach using prehospital tPA may be effective in reducing call-to-needle times, but this is currently being scrutinized in a prospective controlled study.

A Game-Theoretic Study on Non-monetary Incentives in Data Analytics Projects with Privacy Implications

The amount of personal information contributed by individuals to digital repositories such as social network sites has grown substantially. The existence of this data offers unprecedented opportunities for data analytics research in various domains of societal importance including medicine and public policy. The results of these analyses can be considered a public good which benefits data contributors as well as individuals who are not making their data available. At the same time, the release of personal information carries perceived and actual privacy risks to the contributors. Our research addresses this problem area. In our work, we study a game-theoretic model in which individuals take control over participation in data analytics projects in two ways: 1) individuals can contribute data at a self-chosen level of precision, and 2) individuals can decide whether they want to contribute at all (or not). From the analyst's perspective, we investigate to which degree the research analyst has flexibility to set requirements for data precision, so that individuals are still willing to contribute to the project, and the quality of the estimation improves. We study this tradeoffs scenario for populations of homogeneous and heterogeneous individuals, and determine Nash equilibrium that reflect the optimal level of participation and precision of contributions. We further prove that the analyst can substantially increase the accuracy of the analysis by imposing a lower bound on the precision of the data that users can reveal.
Fluid particle dynamics: A synthesis of dissipative particle dynamics and smoothed particle dynamics

We present a generalization of dissipative particle dynamics that includes shear forces between particles. The new algorithm has the same structure as the (isothermal) smoothed particle dynamics algorithm, except that it conserves angular momentum and includes thermal fluctuations consistently with the principles of equilibrium statistical mechanics. This clarifies the connection of dissipative particle dynamics with numerical resolution algorithms of the macroscopic Navier-Stokes equations.
New results on holographic three point functions

We exploit a gauge invariant approach for the analysis of the equations governing the dynamics of active scalar fluctuations coupled to the fluctuations of the metric along holographic RG flows. In the present approach, a second order ODE for the active scalar emerges rather simply and makes it possible to use the Green's function method to deal with (quadratic) interaction terms. We thus fill a gap for active scalar operators, whose three-point functions have been inaccessible so far, and derive a general, explicitly Bose symmetric formula thereof. As an application we compute the relevant three-point function along the GPPZ flow and extract the irreducible trilinear couplings of the corresponding superglueballs by amputating the external legs on-shell.
Functional independence and mobility in kidney transplanted patients: cross-sectional study

- Aim — To assess functional independence, balance and mobility of kidney transplant recipients, to verify transplant time, donor type, regular exercise practice, musculoskeletal complaints, as well as association among these variables. Methods: Observational study with 86 kidney transplant individuals, subjected to evaluation of the Functional Independence Measure (FIM) and Timed Up and Go test (TUG). Results: The mean age of the study population was 43.98 years old, 50% of these individuals were between 5-10 years of transplantation and 50% between 10-15 years. Changes in mobility and balance (TUG) were found in 9.3% of transplant patients, while 2.3% had deficits in functional independence (FIM). The association between TUG and the FIM (χ2= 19.964, p< 0.001) was found in 25% of the 9.3% of individuals who showed changes in TUG. It was found that only 20.9% of kidney transplant between 5-10 years and 14.0% between 11 and 15 years performed regular physical exercises (χ2= 0.727, p= 0.394) and 67.4% presented prevalent complaints on lower limbs musculoskeletal. Conclusion: Although the level of dependence and impairments in mobility and balance found in renal transplants are low, deficits in mobility and balance may lead to changes in the ability to perform their functional activities independently.
Chapter 4 Modulation of Gamma and Spindle-Range Power by Slow Waves in Scalp Sleep EEG of Children

Deep sleep is characterized by slow waves of electrical activity in the cerebral cortex. They represent alternating down–states and up–states of, respectively, hyperpolarization with accompanying neuronal silence and depolarization during which neuronal firing resumes. The up states give rise to faster oscillations, notably spindles and gamma activity which appear of major importance for the role of sleep in brain function and cognition. Unfortunately, while spindles are easily detectable, gamma oscillations are of very small amplitude. No previous sleep study has succeeded in demonstrating modulations of gamma power along the time course of slow waves in human scalp electroencephalography (EEG). As a consequence, progress in our understanding of the functional role of gamma modulation during sleep has been limited to animal studies and exceptional human studies, notably those of intracranial recordings in epileptic patients. Because high synaptic density, which peaks some time before puberty depending on the brain region (Huttenlocher and Dabholkar, 1997), generates oscillations of larger amplitude, we considered that the best chance to demonstrate a modulation of gamma power by slow wave phase in regular scalp sleep EEG would be in school-aged children. Sleep EEG was recorded in 30 healthy children (aged 10.7 ± 0.8 years; mean ± s. d.). Time-frequency analysis was applied to evaluate the time course of spectral power along the development of a slow wave. Moreover, we attempted to modify the sleep architecture and sleep characteristics through automated acoustic stimulation coupled to the occurrence of slow waves in one subset of the children. Gamma power increased on the rising slope and positive peak of the slow wave. Gamma and spindle activity is strongly suppressed during the negative peak. There were no differences between the groups who received and did not receive acoustic stimulation in the sleep parameters and slow wave-locked time-frequency analysis. Our findings show, for the first time in scalp EEG in humans, that gamma activity is associated with the upgoing slope and peak of the slow wave. We propose that studies in children provide a uniquely feasible opportunity to conduct investigations into the role of gamma during sleep.
Selfing, adaptation and background selection in finite populations

Classic deterministic genetic models of the evolution of selfing predict species should be either completely outcrossing or completely selfing. However, even species considered high selfers outcross to a small degree (e.g. Arabidopsis thaliana and Caenorhabditis elegans). This discrepancy between theory and data may exist because the classic models ignore the effects of drift interacting with selection, that is, Hill–Robertson effects. High selfing rates make the effective rate of recombination near zero, which is expected to cause the build‐up of negative disequilibria in finite populations. Despite the transmission advantage associated with complete selfing, low levels of outcrossing may be favoured because of the benefits of increasing the effective rate of recombination to dissipate negative disequilibria. Using multilocus simulations, we confirm that selfing reduces effective population size through background selection and causes negative disequilibria between selected sites. Consequently, the rate of adaptation is substantially reduced in strong selfers. When selfing rate is allowed to evolve, populations evolve to be either strong outcrossers or strong selfers, depending on the parameter values. Amongst selfers, low, but nonzero, levels of outcrossing can be maintained by selection even when all mutations are deleterious; more outcrossing is maintained with higher rates of deleterious mutation. The addition of beneficial mutations can (i) lead to a quantitative increase in the degree of outcrossing amongst stronger selfers but (ii) may cause outcrossing species to evolve into stronger selfers.

Educational justice, segregated schooling and vocational education

The philosophical debate on educational justice currently focusses on the Anglo-American situation. This essay brings in an additional perspective. It provides a justice-oriented critique of the segregated education systems in German-speaking countries. First, arguments that are commonly put forward in favour of these systems are rejected. Second, an additional argument against early tracking in education is formulated. It is claimed that segregated education systems tend to undermine children’s ‘right to an open future’. It is also explained that the segregated systems in Germany, Austria and Switzerland are linked to well-established systems of vocational education and training. It is argued, in this essay, that a workplace-based vocational system can be an important element of a just education system. The proposal is, then, to introduce a comprehensive school system in the first 8 or 9 school years that prepares students for both the vocational system and the academic track (Gymnasium). Against this background, a so-called threshold conception of educational justice – that contains two different threshold levels – is formulated.
Ethnographic Field Research: Interpreting One's entrance into the Field as Thrownness

The field is where an ethnographer does the fieldwork, yet a discussion of one´s entrance into the field is essentially overlooked in the IS research literature. This paper suggests that entrance into the field can be seen as a rite of passage into a practice world. Using phenomenological hermeneutics, we direct the focus to everyday being-in-the-world to develop a practical understanding of the field as a fusion of horizons where an ethnographer is thrown. The concept of thrownness suggests including one´s historicity and prejudices as one enters the field. We provide some empirical evidence from an ethnographic field study at a large scale IT services organization. This paper is intended as a contribution to the discussion about qualitative research methods in information systems.

In this mini-review, I overviewed non-motor symptoms and signs in PD.
Race and Stratification in College Enrollment Over Time

We measure college enrollment selectivity gaps by race-ethnicity using a novel method that is sensitive to both the level (2- vs. 4-year) and selectivity of the college in which students enroll. We find that overall Hispanic–White and Black–White enrollment selectivity gaps closed in the United States between 1986 and 2014. This overall closing of gaps appears to be related to the closing of high school graduation gaps. However, this contraction was driven almost entirely by students at the margin between no college and college enrolling in non-degree-granting programs. Among students who enrolled in degree-granting schools, Black students have enrolled at increasingly less selective institutions than White students, whereas Hispanic–White gaps remained relatively unchanged over the nearly 30 years of our study. These gaps are concerning because of their implications for long-term economic inequality.

4-Hydroxynonenal regulates mitochondrial function in human small airway epithelial cells

Prolonged exposure to oxidative stress causes Acute Lung Injury (ALI) and significantly impairs pulmonary function. Previously we have demonstrated that mitochondrial dysfunction is a key pathological factor in hyperoxic ALI. While it is known that hyperoxia induces the production of stable, but toxic 4-hydroxynonenal (4-HNE) molecule, it is unknown how the reactive aldehyde disrupts mitochondrial function. Our previous in vivo study indicated that exposure to hyperoxia significantly increases 4-HNE-Protein adducts, as well as levels of MDA in total lung homogenates. Based on the in vivo studies, we explored the effects of 4-HNE in human small airway epithelial cells (SAECs). Human SAECs treated with 25 μM of 4-HNE showed a significant decrease in cellular viability and increased caspase-3 activity. Moreover, 4-HNE treated SAECs showed impaired mitochondrial function and energy production indicated by reduced ATP levels, mitochondrial membrane potential, and aconitase activity. This was followed by a significant decrease in mitochondrial oxygen consumption and depletion of the reserve capacity. The direct effect of 4-HNE on the mitochondrial respiratory chain was confirmed using Rotenone. Furthermore, SAECs treated with 25 μM 4-HNE showed a time-dependent depletion of total Thioredoxin (Trx) proteins and Trx activity. Taken together, our results indicate that 4-HNE induces cellular and mitochondrial dysfunction in human SAECs, leading to an impaired endogenous antioxidant response.
