Adaptive Link Assignment Applied in Case of Video Streaming in a Multilink Environment

Nowadays the importance of multilink networks where end-to-end connections are provided by applying multiple communication links simultaneously is rapidly growing due to the expanding demand for high-speed Internet access and real-time video transmission. Since channel conditions may vary in time and space, the selection of the used communication links depends on traffic load, latency, coverage and desired data rate. Combining multilink architecture and adaptive video transmission can be therefore an effective solution for broadcasting video streams. In this paper the efficiency of the adaptive transmission scheme will be presented for a terrestrial heterogeneous multilink network which consists of WiMAX, LTE and HSDPA communication links.
Failure to detect immunocytochemically reactive endogenous lectin on the cell surface of Dictyostelium discoideum

The endogenous lectins of Dictyostelium discoideum, called discoidins I and II, have been implicated in cell cohesion during the associative phase of this organism. In an effort to repeat and extend the studies of these putative cell-surface proteins, we attempted a variety of immunocytochemical techniques. Antibodies to a mixture of the purified discoidins were raised in rabbit. Both living and fixed cells were examined by indirect immunoferritin labeling using whole antiserum and by direct immunolabeling using purified specific IgG adsorbed to colloidal gold. Cells, at the appropriate stage, of strains A3, NC-4, and WS-582 were tested. In no instance were cell surface antigens detected despite meticulous efforts to duplicate the published techniques and to extend and refine them. Specific localization was found only in the cytosol and on the cytoplasmic face of certain endomembrane vesicles, and much less so on outer nuclear and mitochondrial membranes, in inadvertently disrupted cells. In no case was specific label found on either side of the plasma membrane or on food vacuoles. Exogenously supplied discoidins, bound to cells, were successfully localized by our technique. We conclude that the discoidins are not present on the cell surface, or are there in undetectable quantities, during the associative phase. We suggest that previous demonstrations of these proteins at the cell surface were artifacts resulting from the way in which the cells were handled, which caused the binding of externalized discoidins, possibly those released from lysed cells. We believe that the current notion that the discoidins play a direct role in cell cohesion by virtue of their carbohydrate-binding capacity should be reexamined. We suggest that the true role of the discoidins is solely intracellular.
Contrasting Hippocampal and Perirhinalcortex Function using Immediate Early Gene Imaging

The perirhinal cortex and hippocampus have close anatomical links, and it might, therefore, be predicted that they have close, interlinked roles in memory. Lesion studies have, however, often failed to support this prediction, providing dissociations and double dissociations between the two regions on tests of object recognition and spatial memory. In a series of rat studies we have compared these two regions using the expression of the immediate early gene c-fosas a marker of neuronal activity. This gene imaging approach makes it possible to assess the relative involve-ment of different brain regions and avoids many of the limitations of the lesion approach. A very consistent pattern of results was found as the various hippocampal subfields but not the peri-rhinal cortex show increased c-fosactivity following tests of spatial learning. In contrast, the perirhinal cortex but none of the hippocampal subfields show increased c-fosactivity when presented with novel rather than familiar visual objects. When novel scenes are created by the spatial rearrangement of familiar objects it is the hippocampus and not the perirhinal cortex that shows c-foschanges. This double dissociation for gene expression accords with that found from lesion studies and highlights the different contributions of the perirhinal cortex and hippocampus to memory.
The design of a new instrument to assess leadership dimensions and styles

This paper explores a way in which the authors’ research into Emotional Intelligence and senior management (leaders’) competencies has been developed into a framework for assessing an individual’s leadership style within a context that aligns with the conclusions drawn from their review of the leadership literature. Details are presented on the development of a new questionnaire, The Leadership Dimensions Questionnaire (LDQ), to measure 15 leadership dimensions/constructs. Two pilot studies of the new LDQ are described on a total sample of 222 managers. Data are presented on two item analyses conducted to refine the pilot form. Acceptable reliability and face, content and construct validity of the final instrument was demonstrated. Construct validity was investigated by correlating LDQ scores with personality and team role data. Three new styles of Leadership, similar to Transformational, Transactional and Participative styles, are proposed and research on these styles is reported. A difference (d2) measure is then used to calculate differences between the manager’s own profile and the mean profile for each style. Difference measures for each style are then related to data on managers’ job function, gender, sector and nationality and on their Personality and Team Role data. Advice on interpreting the styles is also provided. Finally, a discussion of the results of the study and proposals for further work are presented.
Actividad física y perfil anímico en un sector de la población sevillana

Se analizan las relaciones existentes entre cantidad y tipo de actividad fisica (CAF) y estado de animo (EA). 310 sujetos clasificados por grupo de edad, sexo y estilo de vida contestaron a los cuestionarios Profile of Mood State (POMS) y el International Physical Activity Questionnaire (IPAQ) con el fin de conocer su perfil animico y su relacion con la cantidad y tipo de actividad fisica realizada. Relaciones altas y moderadas entre diferentes variables revelan asociaciones entre subescalas negativas de EA y CAF. Independientemente de la edad y sexo, en general la CAF realizada se relaciona negativamente con subescalas negativas del POMS y positivamente con las positivas. Consideramos la necesidad de nuevos estudios que permitan cuantificar la cantidad minima de actividad fisica necesaria para la existencia de estos efectos y que permitan discernir si la misma se realiza de manera espontanea o dirigida
Towards a science of user engagement (Position Paper)

User engagement is a key concept in designing user-centred web applications. It refers to the quality of the user experience that emphasises the positive aspects of the interaction, and in particular the phenomena associated with being cap-tivated by technology. This deﬁnition is motivated by the observation that successful technologies are not just used, but they are engaged with. Numerous methods have been proposed in the literature to measure engagement, however, little has been done to validate and relate these measures and so provide a ﬁrm basis for assessing the quality of the user experience. Engagement is heavily inﬂuenced, for example, by the user interface and its associated process ﬂow, the user’s context, value system and incentives. In this paper we propose an approach to relating and developing uniﬁed measures of user engagement. Our ultimate aim is to deﬁne a framework in which user engagement can be studied, measured, and explained, leading to recommendations and guidelines for user interface and interaction design for front-end web technology. Towards this aim, in this paper, we consider how existing user engagement metrics, web analytics, information retrieval metrics, and measures from immersion in gaming can bring new perspective to deﬁning, measuring and explaining user engagement.
Family configuration and maternal employment: effects on family environment and children's outcomes

The purpose of this study was to investigate the effects of maternal employment on children's outcomes and the social climate within divorced (N = 38) and intact (N = 38) middle class families having elementary school children. Parental perceptions of specific family environment characteristics (Moos & Moos, 1986) and children's behavioral conduct (Achenbach & Edelbrock, 1983) were assessed, Children's outcome characteristics were measured using the Harter Self Perception Profile For Children(Harter, 1985). These data were analyzed using a multiple regression model. As expected, signficantly more mothers were employed in the divorced group. In divorced homes, maternal employment was significantly associated with increased active recreational orientation within the family enviroment and increased self-esteem in children. The data suggest that when mothers are employed in families who have experienced parental divorce, there is moree of an inclination to participate in social and recreational activities tog.
Blastogenic response of human lymphocytes to oral bacterial antigens: comparison of individuals with periodontal disease to normal and edentulous subjects

Cell-mediated immunity in humans to antigens derived from oral plaque bacteria was investigated by using the lymphocyte blastogenesis assay. Subjects with varying severities of periodontal disease including normal, gingivitis, periodontitis, and edentulous were compared. Mononuclear leukocytes were separated from peripheral blood and cultured with antigens prepared by sonication of Actinomyces viscosus (AV), Actinomyces naeslundii (AN), Veillonella alcalescens (VA), Leptotrichia buccalis (LB), Bacteroides melaninogenicus (BM), and homologous dental plaque (DP). The lymphocyte response of subjects with gingivitis or periodontitis was significantly greater than that of normal subjects to antigens of AV, AN, and DP, but did not differ from the response of edentulous subjects. Periodontitis subjects were significantly more reactive than edentulous and normal subjects in response to VA, LB, and BM. These findings suggest that the tested gram-negative bacteria and the host response they evoke are associated with advanced periodontal destruction.
Human Rap1 modulates TRF2 attraction to telomeric DNA

More than two decades of genetic research have identified and assigned main biological functions of shelterin proteins that safeguard telomeres. However, a molecular mechanism of how each protein subunit contributes to the protecting function of the whole shelterin complex remains elusive. Human Repressor activator protein 1 (Rap1) forms a multifunctional complex with Telomeric Repeat binding Factor 2 (TRF2). Rap1–TRF2 complex is a critical part of shelterin as it suppresses homology-directed repair in Ku 70/80 heterodimer absence. To understand how Rap1 affects key functions of TRF2, we investigated full-length Rap1 binding to TRF2 and Rap1–TRF2 complex interactions with double-stranded DNA by quantitative biochemical approaches. We observed that Rap1 reduces the overall DNA duplex binding affinity of TRF2 but increases the selectivity of TRF2 to telomeric DNA. Additionally, we observed that Rap1 induces a partial release of TRF2 from DNA duplex. The improved TRF2 selectivity to telomeric DNA is caused by less pronounced electrostatic attractions between TRF2 and DNA in Rap1 presence. Thus, Rap1 prompts more accurate and selective TRF2 recognition of telomeric DNA and TRF2 localization on single/double-strand DNA junctions. These quantitative functional studies contribute to the understanding of the selective recognition of telomeric DNA by the whole shelterin complex.
Frequency of modifiable risk factors in stroke patients.

BACKGROUND Stroke is one of the common causes of admission in medical and neurology units in hospitals. The aim of this study was to find out the frequency of modifiable risk factors, and association of ischaemic stroke with these risk factors in stroke patients admitted in Ayub Teaching Hospital Abbottabad. METHODS This a cross-sectional descriptive hospital based study, carried out in medical units of Ayub Teaching Hospital, Abbottabad on 150 patients with stroke. Thorough history, clinical examination and appropriate investigations were performed to collect all the relevant information. CT scan was done to confirm the diagnosis. RESULTS Out of 150 subjects, 90 (60%) were males, while 60 (40%) were females. Ischaemic stroke was found in 105 (70%) patients and 45 (30%) were having haemorrhagic stroke. The risk factors were hypertension in 127 (84.7%), diabetes 31 (20.7%), Coronary artery diseases 31 (20.7%), previous TIA/stroke 42 (28%), smoking 28 (16.7%) and obesity 16 (10.7%). CONCLUSION There was no statistically significant association between risk factors and type of stroke except coronary artery diseases.
Physical Illness and Psychosis

Summary One hundred psychotic patients referred to a consultation service in a general hospital were compared with 50 psychotic patients without physical illness in a psychiatric unit. Background, mental and cognitive state were evaluated. In addition to providing a list of likely causes of cerebral dysfunction in such a sample, the study revealed an increased incidence of prior depression in those with cerebral dysfunction, and identified a group where psychosocial factors appeared more significant than cerebral dysfunction in determining the psychosis. The various ways in which a psychosis can be associated with a physical condition, and the various forms that it can take even when cerebral dysfunction is present, are discussed.

Enterprise Service Bus: A Performance Evaluation

The flexibility offered by an Enterprise Service Bus (ESB) in enabling various applications to exchange data makes it a very important middleware layer that is responsible for transporting data in a Service-Oriented Architecture (SOA). The popularity of the ESB has given rise to a number of commercial off the shelf (COTS) products as well as open source ESBs. In this study, we evaluated three open source ESBs and compared them both qualitatively and quantitatively. The empirical results were statistically tested to determine the statistical significance of the results.
Diverse expression of ErbB receptor proteins during rat liver development and regeneration.

BACKGROUND & AIMS The protein expression and interactions of the ErbB receptors were examined in different liver proliferation models in vivo and in vitro, including ontogeny and regeneration following partial hepatectomy. METHODS Expression and tyrosine phosphorylation status of specific ErbB proteins were studied by immunologic methods. RESULTS The epidermal growth factor receptor, ErbB2, and ErbB3 were the only ErbB proteins detected in the liver parenchyma on embryonic day 19. ErbB2 disappeared by the third week after birth and could not be appreciably induced in the adult animal by partial hepatectomy. ErbB2 was also detected in multipotent stem (RLE) and hepatoma (H4IIe) cell lines as well as in fetal, but not adult, hepatocyte cultures. Only epidermal growth factor receptor and ErbB3 were detected in adult liver, and both showed circadian variation in protein expression. ErbB4 was not detected in any model. Patterns of ligand-induced ErbB phosphorylation differed between fetal and adult hepatocytes. CONCLUSIONS Complex and independent programs regulate the ErbB receptors, with implications for differential cell signaling in hepatic development and regeneration.
[Panhypopituitarism secondary to pituitary metastases].

BACKGROUND Hypophyseal metastatic localizations are uncommon and rarely the first expression of a primary cancer. We report an exceptional case revealed by panhypopituitarism and diabetes insipidis. CASE REPORT Brain MRI visualized an intra- and suprasellar tumoral formation found to be a cribiform adenocarcinoma. The primary tumor could not be identified. Despite radiotherapy, surgery and chemotherapy combining carboplatin and etoposide, the tumor progressed with the development of cervical and mediastinal nodes. The patient died one year after onset of the clinical signs. DISCUSSION Diagnosis of hypophyseal metastasis is mainly based on indirect evidence: rapid course, invasion of neighboring structures. Optimal management of these rare tumors remains to be determined.
Video Telephony for End-Consumers: Measurement Study of Google+, iChat, and Skype

Video telephony requires high-bandwidth and low-delay voice and video transmissions between geographically distributed users. It is challenging to deliver high-quality video telephony to end-consumers through the best-effort Internet. In this paper, we present our measurement study on three popular video telephony systems on the Internet: Google+, iChat, and Skype. Through a series of carefully designed active and passive measurements, we uncover important information about their key design choices and performance, including application architecture, video generation and adaptation schemes, loss recovery strategies, end-to-end voice and video delays, resilience against random and bursty losses, etc. The obtained insights can be used to guide the design of applications that call for high-bandwidth and low-delay data transmissions under a wide range of “best-effort” network conditions.
Gender of Desire, The: Essays on Male Sexuality

Here, one of the world’s pioneers in the field of masculinity studies explores the construction of male sexuality, pornography, and sexual violence. Michael S. Kimmel analyzes what male sexuality is, where it comes from, how it works, what affects it, pornography’s impact on it, what fantasies men have about sex, what people think about sex, and how male ideas about sex affect what men actually do. Provocative and wide-ranging, these essays make important contributions to sociology, queer theory, American studies, history, and studies of gender, sexuality, and gay and lesbian issues.
Rotylenchulus reniformis Management in Cotton with Crop Rotation.

One-year crop rotations with corn or highly resistant soybean were evaluated at four locations for their effect on Rotylenchulus reniformis population levels and yield of a subsequent cotton crop. Four nematicide (aldicarb) regimes were included at two of the locations, and rotation with reniform-susceptible soybean was included at the other two locations. One-year rotations to corn or resistant soybean resulted in lower R. reniformis population levels (P </= 0.05) than those found in cotton at three test sites. However, the effect of rotation on nematode populations was undetectable by mid-season when cotton was grown the following year. Cotton yield following a one-year rotation to resistant soybean increased at all test locations compared to continuous cotton, and yield following corn increased at three locations. The optimum application rate for aldicarb in this study was 0.84 kg a.i./ha in furrow. Side-dress applications of aldicarb resulted in yield increases that were insufficient to cover the cost of application in 3 of the 4 years.

The leverage effect has become an extensively studied phenomenon that describes the (usually) negative relation between stock returns and their volatility. Although this characteristic of stock returns is well acknowledged, most studies of the phenomenon are based on cross-sectional calibration with parametric models. On the statistical side, most previous works are conducted over daily or longer return horizons, and few of them have carefully studied its estimation, especially with high-frequency data. However, estimation of the leverage effect is important because sensible inference is possible only when the leverage effect is estimated reliably. In this article, we provide nonparametric estimation for a class of stochastic measures of leverage effect. To construct estimators with good statistical properties, we introduce a new stochastic leverage effect parameter. The estimators and their statistical properties are provided in cases both with and without microstructure noise, under the stochastic volatility model. In asymptotics, the consistency and limiting distribution of the estimators are derived and corroborated by simulation results. For consistency, a previously unknown bias correction factor is added to the estimators. Applications of the estimators are also explored. This estimator provides the opportunity to study high-frequency regression, which leads to the prediction of volatility using not only previous volatility but also the leverage effect. The estimator also reveals a theoretical connection between skewness and the leverage effect, which further leads to the prediction of skewness. Furthermore, adopting the ideas similar to the estimation of the leverage effect, it is easy to extend the methods to study other important aspects of stock returns, such …
Surround-see: enabling peripheral vision on smartphones during active use

Mobile devices are endowed with significant sensing capabilities. However, their ability to 'see' their surroundings, during active use, is limited. We present Surround-See, a self-contained smartphone equipped with an omni-directional camera that enables peripheral vision around the device to augment daily mobile tasks. Surround-See provides mobile devices with a field-of-view collinear to the device screen. This capability facilitates novel mobile tasks such as, pointing at objects in the environment to interact with content, operating the mobile device at a physical distance and allowing the device to detect user activity, even when the user is not holding it. We describe Surround-See's architecture, and demonstrate applications that exploit peripheral 'seeing' capabilities during active use of a mobile device. Users confirm the value of embedding peripheral vision capabilities on mobile devices and offer insights for novel usage methods.
