Double-Layer Video Transmission Over Decode-and-Forward Wireless Relay Networks Using Hierarchical Modulation

We consider a wireless relay network with a single source, a single destination, and a multiple relay. The relays are half-duplex and use the decode-and-forward protocol. The transmit source is a layered video bitstream, which can be partitioned into two layers, a base layer (BL) and an enhancement layer (EL), where the BL is more important than the EL in terms of the source distortion. The source broadcasts both layers to the relays and the destination using hierarchical 16-QAM. Each relay detects and transmits successfully decoded layers to the destination using either hierarchical 16-QAM or QPSK. The destination can thus receive multiple signals, each of which can include either only the BL or both the BL and the EL. We derive the optimal linear combining method at the destination, where the uncoded bit error rate is minimized. We also present a suboptimal combining method with a closed-form solution, which performs very close to the optimal. We use the proposed double-layer transmission scheme with our combining methods for transmitting layered video bitstreams. Numerical results show that the double-layer scheme can gain 2-2.5 dB in channel signal-to-noise ratio or 5-7 dB in video peak signal-to-noise ratio, compared with the classical single-layer scheme using conventional modulation.
Safety Evaluation of Physical Human-Robot Interaction via Crash-Testing

The light-weight robots developed at the German Aerospace Center (DLR) are characterized by their low inertial properties, torque sensing in each joint and a load to weight ratio similar to humans. These properties qualify them for applications requiring high mobility and direct interaction with human users or uncertain environments. An essential requirement for such a robot is that it must under no circumstances pose a threat to the human operator. To actually quantify the potential injury risk emanating from the manipulator, impact test were carried out using standard automobile crash-test facilities at the German Automobile Club ADAC. In our evaluation we focused on unexpected rigid frontal impacts, i.e. injuries caused by sharp edges are excluded. Several injury mechanisms and so called Severity Indices are evaluated and discussed with respect to their adaptability to physical human-robotic interaction.
Campaigning for Hearts and Minds: How Emotional Appeals in Political Ads Work

It is common knowledge that televised political ads are meant to appeal to voters' emotions, yet little is known about how or if these tactics actually work. Ted Brader's innovative book is the first scientific study to examine the effects that these emotional appeals in political advertising have on voter decision-making. At the heart of this book are ingenious experiments, conducted by Brader during an election, with truly eye-opening results that upset conventional wisdom. They show, for example, that simply changing the music or imagery of ads while retaining the same text provokes completely different responses. He reveals that politically informed citizens are more easily manipulated by emotional appeals than less-involved citizens and that positive "enthusiasm ads" are in fact more polarizing than negative "fear ads. " Black-and-white video images are ten times more likely to signal an appeal to fear or anger than one to enthusiasm or pride, and the emotional appeal triumphs over the logical appeal in nearly three-quarters of all political ads. Brader backs up these surprising findings with an unprecedented survey of emotional appeals in contemporary political campaigns. Politicians do set out to campaign for the hearts and minds of voters, and, for better or for worse, it is primarily through hearts that minds are won. "Campaigning for Hearts and Minds" will be indispensable for anyone wishing to understand how American politics is influenced by advertising today.
Forward transport of proteins in the plasma membrane of migrating cerebellar granule cells

Significance Newly differentiated neurons migrate over long distances to reach their proper destination in the developing brain. The mechanisms by which neurons accomplish this translocation remain to be clarified. By analyzing the trajectories of antibody-coated single quantum dots bound to specific plasma membrane proteins, we found that membrane proteins of migrating cultured cerebellar granule cells exhibited net forward translocation in a form of biased drift, which is superimposed upon Brownian motion, and that this biased drift appears to be driven by myosin II-dependent active transport processes. Thus, plasma membrane proteins undergo forward translocation in unison with cytoplasmic components in migrating neurons. Directional flow of membrane components has been detected at the leading front of fibroblasts and the growth cone of neuronal processes, but whether there exists global directional flow of plasma membrane components over the entire migrating neuron remains largely unknown. By analyzing the trajectories of antibody-coated single quantum dots (QDs) bound to two membrane proteins, overexpressed myc-tagged synaptic vesicle-associated membrane protein VAMP2 and endogenous neurotrophin receptor TrkB, we found that these two proteins exhibited net forward transport, which is superimposed upon Brownian motion, in both leading and trailing processes of migrating cerebellar granule cells in culture. Furthermore, no net directional transport of membrane proteins was observed in nonmigrating cells with either growing or stalling leading processes. Analysis of the correlation of motion direction between two QDs on the same process in migrating neurons also showed a higher frequency of correlated forward than rearward movements. Such correlated QD movements were markedly reduced in the presence of myosin II inhibitor blebbistatin, suggesting the involvement of myosin II-dependent active transport processes. Thus, a net forward transport of plasma membrane proteins exists in the leading and trailing processes of migrating neurons, in line with the translocation of the soma.
Regional Inflation Dynamics within and Across Euro Area Countries and a Comparison with the Us

We investigate co-movements and heterogeneity in inflation dynamics of different regions within and across euro area countries using a novel disaggregate dataset to improve the understanding of inflation differentials in the European Monetary Union. We employ a model where regional inflation dynamics are explained by common euro area and country specific factors as well as an idiosyncratic regional component. Our findings indicate a substantial common area wide component, that can be related to the common monetary policy in the euro area and to external developments, in particular exchange rate movements and changes in oil prices. The effects of the area wide factors differ across regions, however. We relate these differences to structural economic characteristics of the various regions. We also find a substantial national component. Our findings do not differ substantially before and after the formal introduction of the euro in 1999, suggesting that convergence has largely taken place before the mid 90s. Analysing US regional inflation developments yields similar results regarding the relevance of common US factors. Finally, we find that disaggregate regional inflation information, as summarised by the area wide factors, is important in explaining aggregate euro area and US inflation rates, even after conditioning on macroeconomic variables. Therefore, monitoring regional inflation rates within euro area countries can enhance the monetary policy maker's understanding of aggregate area wide inflation dynamics.
Narrative Exposure Therapy as Treatment for Posttraumatic Stress Disorder: An Intervention Study

Background: Narrative Exposure Therapy (NET) is a treatment method defined as a standardized, short-term intervention for treating posttraumatic stress disorder (PTSD). NET has mainly been applied on victims of organized violence and whose life conditions are threatening and unsafe. There are no published studies of NET applied on PTSD patients living in Norway with another trauma history than war-traumas. Aim of the study: To investigate the effect of NET on diagnosed PTSD symptoms, general psychological status and depression symptoms in a sample of 10 adult patients recruited from outpatient clinics in Health-region West. Method: The patients were assessed with the Clinical Administered PTSD-scale for DSM-IV (CAPS), the Symptom Checklist -90-Revised (SCL-90-R) and the Beck Depression Inventory (BDI-II) before and one month after NET-treatment. Results: Ttests for dependent samples showed a significant reduction on 5 of 6 subscales on CAPS (n=10) post-treatment and 50% of the patients did no longer fulfil the PTSD criteria. On SCL90-R (n=8) there was a significant reduction of the somatisation subscale. Reduction in the total depression score on BDI-II (n=9) were borderline significant. Conclusion: The results indicate that NET can be a promising treatment method for PTSD patients living in nonthreatening and safe life-conditions in Norway.
Obesity, physical fitness, and inflammatory markers in Polish children

Background The relationship between obesity, physical fitness, and inflammation was analyzed in a Polish population aged 12 to 18 years. Material/Methods Body mass index measurements and Eurofit physical fitness tests were undertaken to assess the adiposity and physical fitness status, respectively, of subjects. Serum samples were collected to measure standard inflammatory markers, including interleukin 6; and the acute-phase proteins alpha1-acid glycoprotein and alpha1-antichymotrypsin. In addition, the glycosylation profiles of alpha1-acid glycoprotein and alpha1-antichymotrypsin were analyzed to further evaluate immune statuses. Results The physical fitness of individuals was negatively influenced by obesity. Obese subjects were characterized by an abnormal immune balance, including increased levels of alpha1-acid glycoprotein, as well as alpha1-antichymotrypsin, and altered glycosylation profiles indicative of an underlying inflammatory condition. Older age, male sex, and a large body mass index appeared to correlate with poor physical fitness scores and a disturbed immune status. Conclusions Impaired physical fitness is indicative for non-compensated overweight and affects mainly males aged 15 to 18 years. Female subjects seemed to cope better with increased body mass.
Age and gender differences in emotional and behavioural problems during the transition to residential treatment: the Odyssey Project

Utilising a national sample of 1,167 young people in residential treatment, this study explored whether the behav-ioural problems exhibited during the transition to residential treatment varied depending upon the age and gender of the youngsters. Specifically, we asked whether those who were admitted to residential treatment centres (RTCs) aged under 12 had a different set of behavioural problems from those who were 12 years and older when admitted, and whether boys had different characteristics than girls. The 11 scales of the Achenbach Child Behavior Checklist were examined. The results revealed statistically significant patterns of associations by age and gender. As populations shift within agencies and across time, knowledge of the behavioural problems associated with age and gender groups can be used to facilitate agency planning and staff training.
Piezoresistive Carbon Foams in Sensing Applications

Mechanical strain sensing is ubiquitous, found in applications such as heart rate monitoring, analysis of body part motion, vibration of machines, dilatation in buildings and large infrastructure, and so forth. Piezoresistive materials and sensors based on those offer versatile and robust solutions to measure strains and displacements and can be implemented even in acceleration and pressure analyses. In this paper, we overview the most prominent piezoresistive materials, and present a case study on carbon foams as well as on their hierarchical hybrid structures with carbon nanotubes/nanofibers. Our results show highly nonlinear electrical resistance and mechanical stress dependence on uniaxial strain in both types of materials up to 50% compression. The Young’s moduli increase with compressive strain between 1-65 kPa and 0.1-92 kPa for the foam and hierarchical structure, respectively. The foams have giant gauge factors (up to -1000) with large differential gauge factors (on the scale of -10) and differential pressure sensitivity of 0.016 1/Pa (at 10% strain) making them suitable for detecting both small and large displacements with excellent accuracy of electrical readout as we demonstrate in detecting building wall displacement as well as in monitoring heart rate and flexing of fingers.

Quantitative comparison of erythropoietin receptor levels in the epithelial versus endothelial fractions of primary breast tumors.

BACKGROUND Erythropoietin (EPO) was shown to reduce tumor survival in recent trials, however, its mechanisms of action are unclear. Efforts to measure tumor EPO receptor (EPOR) are limited by the promiscuity of EPOR antibodies, and concerns as to whether EPOR mRNA measurements are confounded by heterogeneity of tumor vasculature, a known EPOR source. MATERIALS AND METHODS This study compared mRNA levels of EPOR and JAK2 in 11 breast tumor epithelial versus endothelial dissections. RESULTS In nine tumors EPOR mRNA was 2.6 (1.2-5.7)-fold lower in the epithelial fraction, however, this reduction was less than the reduction of endothelial markers. In two tumors, EPOR mRNA was 2.9 (1.7-4.0)-fold higher in the epithelial fraction. The inter-tumor variation in EPOR levels exceeded the intra-tumor variation between fractions. Similar results were obtained for JAK2. CONCLUSION Tumor vasculature is not the sole source of EPOR and JAK2, and tumors can be segregated by EPOR and JAK2 levels for correlative analysis with clinical outcomes.
CXCL16/CXCR6 chemokine signaling mediates breast cancer progression by pERK1/2-dependent mechanisms

Our previous studies demonstrate that CXCL6/CXCR6 chemokine axis induces prostate cancer progression by the AKT/mTOR signaling pathway; however, its role and mechanisms underlying invasiveness and metastasis of breast cancer are yet to be elucidated. In this investigation, CXCR6 protein expression was examined using high-density tissue microarrays and immunohistochemistry. Expression of CXCR6 shows a higher epithelial staining in breast cancer nest site and metastatic lymph node than the normal breast tissue, suggesting that CXCR6 may be involved in breast cancer (BC) development. In vitro and in vivo experiments indicate that overexpression of CXCR6 in BC cells has a marked effect on increasing cell migration, invasion and metastasis. In contrast, reduction of CXCR6 expression by shRNAs in these cells greatly reduce its invasion and metastasis ability. Mechanistic analyses show that CXCL16/CXCR6 chemokine axis is capable of modulating activation of RhoA through activating ERK1/2 signaling pathway, which then inhibits the activity of cofilin, thereby enhancing the stability of F-actin, responsible for invasiveness and metastasis of BC. Taken together, our data shows for the first time that the CXCR6 / ERK1/2/ RhoA / cofilin /F-actin pathway plays a central role in the development of BC. Targeting the signaling pathway may prove beneficial to prevent metastasis and provide a more effective therapeutic strategy for BC.
Self referential and social cognition in adolescents with autistic spectrum disorder

A dominant social cognition model has construed the central socio-communicative impairments in Autistic Spectrum Disorders (ASDs) as deficits in understanding others’ minds- what other people know, intend, believe and feel. Difficulties for individuals with ASD have been well documented on “Theory of Mind” (TOM) tasks designed to tap these skills (Boucher, 2012). Recently however, research has shifted toward exploring how individuals with ASD understand their own minds, and to look at the cognitive mechanisms involved in thinking about “the self”. The present thesis is situated in the context of this emerging self-referential cognition (SRC) research, including its close connection to social cognition. This thesis explored the quantitative and qualitative differences in neurotypical (NT) adolescents and those with ASD in generating self-images (e.g. concepts such as I am a female, I am a footballer, I am kind) through use of novel fluency tasks (the ‘I Am’ and ‘(s)he is’ tasks) based on the Twenty Statements Test (TST; Kuhn and McPartland, 1954). Relationships between these tasks and social cognition (TOM measures) were also explored. The results indicated that both NT adolescents and those with ASD exhibited a self-reference effect (SRE), generating more statements about themselves than other people. The magnitude of the SREs was found to be significantly related to several TOM measures such as performance on the Mind in the Eyes task of emotion recognition. Moreover, the ASD group produced significantly less personal attributions across all fluency tasks, but a similar number of social and physical attributions, compared to the NT group. This mirrored emerging findings that indicate a specific deficit in psychological but not physical self awareness in ASD (e.g. Williams, 2010). Additionally, the ASD group were found to make significantly fewer spontaneous social stereotypes on the (s)he is tasks, such as the “Beauty is Good” stereotype, a finding which contrasts with previous research showing preserved social stereotyping in children with ASD (Fonesca et al, 2011). The theoretical and clinical implications of these findings for individuals with ASD are discussed with reference to the “absent-self hypothesis” (e.g. Frith, 2003). Additionally, the promising utility of fluency measures in capturing important aspects of SRC are also noted, including suggestions for further research.
Hubungan Antara Karakteristik Perawat dengan Motivasi Perawat Pelaksana dalam Menerapkan Komunikasi Terapeutik Pada Fase Kerja Di Rumah Sakit Islam Sultan Agung Semarang

Robust Adaptive Boundary Control of a Vibrating String Under Unknown Time-Varying Disturbance

In this paper, robust adaptive boundary control is developed for a class of flexible string-type systems under unknown time-varying disturbance. The dynamics of the string system is represented by a nonhomogeneous hyperbolic partial differential equation (PDE) and two ordinary differential equations. Boundary control is proposed at the right boundary of the string based on the original distributed parameter system model (PDE) to suppress the vibration excited by the external unknown disturbance. Adaptive control is designed to compensate the system parametric uncertainty. With the proposed robust adaptive boundary control, all the signals in the closed-loop system are guaranteed to be uniformly ultimately bounded. The state of the string system is proven to converge to a small neighborhood of zero by appropriately choosing design parameters. Simulations are provided to illustrate the effectiveness of the proposed control.
