Seamless Spectrum Sensing Scheme for Cognitive Radio System

We propose a new spectrum sensing scheme that utilizes multiple input and multiple output (MIMO) technology to perform spectrum sensing and data transmission simultaneously. By using our proposed scheme, we can reduce the degradation of quality of service that is caused by spectrum sensing and increase the throughput of CR systems. Through performance analysis and numerical results, we show that our proposed scheme can increase the performance of CR systems with respect to throughput and delay.
Experimental deformation of olivine single crystals at lithospheric temperatures

Rheological properties of mantle minerals and rocks at temperatures (T) appropriate to much of Earth's lithosphere have remained poorly constrained, even though past experimental studies on olivine single crystals and polycrystalline aggregates have quantified the high‐temperature creep mechanisms (T > 1200°C). Consequently, we have performed deformation experiments on crystals of San Carlos olivine at lower temperatures, from 900° to 1200°C, in triaxial compression along the [101]c direction. The experiments were carried out at a confining pressure of 300 MPa in a high‐resolution gas‐medium mechanical testing apparatus at differential stresses of 100 to 500 MPa. Several samples were deformed at constant displacement rate and others at constant load, in order to provide insight into possible effects of work‐hardening. Under the deformation conditions investigated, little evidence of work‐hardening was observed. The data follow a power‐law dependence on stress, as in previous high‐temperature deformation studies. The samples were, however, considerably weaker than predicted by the experimentally determined high‐temperature constitutive equation for olivine crystals of this orientation from the study of Bai et al. (1991). The mechanical behavior correlates instead with the weaker of the two mechanisms (flow laws) that contribute to the high‐temperature constitutive equation. Thus, our experiments demonstrate that published high‐temperature constitutive equations overestimate the strength of lithospheric mantle and that the transition to low‐temperature creep occurs at lower temperatures than previously inferred.
Baru Numerical Study of Turbulent Flow in Pipe with Sudden Expansion

The turbulent fluid flow through sudden expansion duct studies raise the knowledge of scientific and contribute many practical applications. The sudden change in the surface geometry of the duct cause the severe pressure gradient, the boundary layer separates at the step edge and forms a recirculation zone. The knowledge about the recirculation zone is useful in study turbulent flow properties. This paper presents a numerical study of 2D turbulence flow was modeled by the standard k-ε, realizable k-ε, and shear stress transport (SST) k-ω models. The stimulation was conducted by a sudden expansion duct with Reynolds number of 20000 at the inlet of the solution and expansion ratio of 1:2. In this research, flow characteristics at the recirculation zone in the sudden expansion pipe are analyzed. The recirculation size, velocity profile and turbulent intensity are compared between three models of turbulence flow. The results show that SST k-ω model has the best prediction of separation flow compared to two others models. Furthermore, the trends of mean velocity of these three models are same as the experimental results. Copyright © 2015 Penerbit Akademia Baru All rights reserved.
A chimeric virus-mouse model system for evaluating the function A chimeric virus-mouse model system for evaluating the function and inhibition of papain-like proteases of emerging coronaviruses and inhibition of papain-like proteases of emerging coronaviruses

To combat emerging coronaviruses, developing safe and efﬁcient platforms to evaluate viral protease activities and the efﬁcacy of protease inhibitors is a high priority. Here, we exploit a biosafety level 2 (BSL-2) chimeric Sindbis virus system to evaluate protease activities and the efﬁcacy of inhibitors directed against the papain-like protease (PLpro) of severe acute respiratory syndrome coronavirus (SARS-CoV), a biosafety level 3 (BSL-3) pathogen. We engineered Sindbis virus to coexpress PLpro and a substrate, murine interferon-stimulated gene 15 (ISG15), and found that PLpro mediates removal of ISG15 (deISGylation) from cellular proteins. Mutation of the catalytic cysteine residue of PLpro or addition of a PLpro inhibitor blocked deISGylation in virus-infected cells. Thus, deISGylation is a marker of PLpro activity. Infection of alpha/beta interferon receptor knockout (IFNAR (cid:2) / (cid:2) ) mice with these chimeric viruses revealed that PLpro deISGylation activity removed
Climate Responses to Solar Variability

During the past three decades a suite of space-based instruments has monitored the Sun’s brightness as well as the Earth’s surface and atmospheric temperatures. The 11-year solar irradiance cycle, shown in Figure 1, is now well characterized, having approximately equal amplitudes of ∼0.1% during the past three solar activity cycles. Solar cycle irradiance variations result from the competing effects of dark sunspots and bright faculae, whose variations are shown separately in Figure 1. But the extant space-base data record is, as yet, too short and of insufficient long-term precision to reliably establish whether longer-term changes are occurring in addition to the solar cycle. Historical solar brightness changes must therefore be estimated indirectly. One approach combines a model of the contemporary irradiance changes in terms of their solar magnetic sources (dark sunspots and bright faculae) with simulated long-term evolution of solar magnetism (Wang et al., 2005). In this way, the solar irradiance increase since the Maunder Minimum is estimated to be slightly larger than the increase in recent activity cycles, and smaller than early estimates, which were based on variations in Sun-like stars and cosmogenic isotopes.
Listen Before You Auscultate: An Active-Learning Approach to Bedside Cardiac Assessment

Introduction Bedside cardiac assessment (BCA) is deficient across a spectrum of noncardiology trainees. Learners not taught BCA well may become instructors who do not teach well, creating a self-perpetuating problem. To improve BCA teaching and learning, we developed a high-quality, patient-centered curriculum for medicine clerkship students that could be flexibly implemented and accessible to other health professions learners. Methods With a constructivist perspective, we aligned learning goals, activities, and assessments. The curriculum used a “listen before you auscultate” framework, capturing patient history as context for a six-step, systematic approach. In the flipped classroom, short videos and practice questions preceded two 1-hour class activities that integrated diagnostic reasoning, pathophysiology, physical diagnosis, and reflection. Activities included case discussions, jugular venous pressure evaluation, heart sound competitions, and simulated conversations with patients. Two hundred sixty-eight students at four US and international medical schools participated. We incorporated feedback, performed thematic analysis, and assessed learners’ confidence and knowledge. Results Low posttest data capture limited quantitative results. Students reported increased confidence in BCA ability. Knowledge increased in both BCA and control groups. Thematic analysis suggested instructional design strategies were effective and peer encounters, skills practice, and encounters with educators were meaningful. Discussion The curriculum supported active learning of day-to-day clinical competencies and promoted professional identity formation alongside BCA ability. Feedback and increased confidence on the late-clerkship posttest suggested durable learning. We recommend approaches to confirm this and other elements of knowledge, skill acquisition, or behaviors and are surveying impacts on professional identity formation-related constructs.

Lithium-induced nephrogenic diabetes insipidus (NDI) is associated with severe polyuria, aquaporin-2 (AQP2) downregulation and cellular remodelling of the collecting duct (CD). Several studies have hypothesized that a likely candidate for lithium entry is the amiloride-sensitive epithelial sodium channel (ENaC). To test whether ENaC is involved in lithium absorption, transgenic mice deficient of α ENaC specifically in the CD (KO mice) and littermate controls were subjected to chronic lithium treatment. This resulted in a marked increase in water intake in controls, but not in KO mice. The lithium-treated controls also exhibited polyuria and reduced urine osmolality, which was not observed in the KO mice. AQP2 protein levels were decreased in cortex/outer medulla and inner medulla (IM) from lithium-treated controls. In KO mice, only AQP2 levels in IM were partly decreased. Immunohistochemistry showed decreased AQP2 labeling in CD of lithium-treated controls compared to lithium-treated KO mice, whereas no changes were observed in connecting tubule (CNT). Lithium induced an increased H + -ATPase expression in IM of the controls, but not in the KO mice. No differences in blood lithium concentrations were observed between the KO and control mice. Thus, the absence of functional ENaC in CD protects the mice from lithium-induced NDI. Apparently, the CNT is able to escape the lithium toxicity. In conclusion our data supports the idea that ENaC-mediated lithium-entry into the CD principal cells is a crucial step within the pathogenesis of lithium-induced NDI.
Design and Implementation of Asynchronous 8-bit Microprocessor

A delay-insensitive asynchronous design methodology, named NULL Convention Logic (NCL), is one of mainstream asynchronous design techniques for low-power robust circuit operation. It offers many advantages over synchronous circuit design having scaling issues in nanometer region such as severe process variations, short channel effects, aging effects, and etc. Therefore, this paper proposes a new design methodology to convert synchronous circuits into NCL circuits in RTL (register transfer level) and a new interfacing block to connect NCL circuits to synchronous circuits/memories or synchronous circuits/memories to NCL circuits. In this paper, the proposed methodology has been evaluated by an 8051 microprocessor designed using a standard 0.35um CMOS technology, and the experimental results show that the proposed asynchronous 8051 microprocessor reduces power consumption by 40% compared with a synchronous 8051 microprocessor.
El comportamiento del consumidor de alimentos ecológicos en España: un estudio exploratorio a partir de variables sociodemográficas y económicas

espanolEl incremento de la demanda de alimentos ecologicos en Espana es un objetivo prioritario, tanto para los agentes del sector, como para las administraciones publicas, en un escenario caracterizado por el aumento continuo de la agricultura ecologica en Espana. En este contexto, explorar la influencia de determinadas variables sociodemograficas y economicas en el consumo de alimentos en Espana es el principal objetivo de este trabajo. Dos principales conclusiones hemos extraido. La primera es que la influencia de las variables no es siempre homogenea, sino que depende del tipo de alimento. La segunda es que el modelo de distribucion comercial es determinante en el nivel de la demanda, al influenciar el nivel de precios, en el caso del aceite de oliva, y la escasa disponibilidad, para las verduras, hortalizas y frutas EnglishThe increase of organic food demand in Spain is a priority aim, for the sector and the civil service, in a context characterized for the continued development of the ecological agriculture in Spain. In this context, the main objective of this paper is to analyze the influence of some socio-demographic and economic variables in the consumption of organic food in Spain. Two conclusions have been infered. First, the influence of the variables depends on the kind of food, it is not always homogeneous. Second, the commercial distribution is decisive in the level of the demand, due to its influence on the price, for the olive oil, and the limited availability for vegetables and fruits.
University of Birmingham In the beginning: role of autonomy support on the motivation, mental health and intentions of participants entering an exercise referral scheme.

Self-determination theory highlights the importance autonomy supportive environments can have on positive health outcomes, yet little is known about whether differential effects occur as a function of who provides this support. Further, there is no research on the role of motivation and the social environment for mental health and intentions to be physically active before entering an exercise referral scheme. This study samples 347 British adults about to start an exercise referral scheme. Regression analyses revealed that the effects of autonomy support on mental health and physical activity intentions differed as a function of who provided the support (offspring, partner, physician), with offspring having the weakest effects. A structural equation model has shown that autonomy support and more autonomous regulations lead to more positive mental health outcomes and stronger intentions to be physically active. Knowledge of the motivation of those about to commence an exercise program can provide important insights for professionals supporting such efforts.
‘THE OLDER ADULT’ DOESN’T EXIST. USING VALUES TO DIFFERENTIATE OLDER ADULTS IN THE DUTCH HOUSING MARKET.

To date most prognoses of older adults in the housing market have been based on average housing preferences and average housing market behaviour of all persons in a certain age cohort. Due to social-cultural and social-economic dynamics, the relationship between age and housing is expected to change for successive cohorts. This study sets out to improve housing preferences estimates by recognizing the growing differentiation among older adults. This heterogeneity is analysed by differentiating older adults on their lifestyles (operationalized as values), using latent class analysis as a clustering technique. These analyses result in older adults being classified into five segments on the basis of their viewpoints, motivations and attitude. Next, for each lifestyle segment a separate discrete choice model is estimated, offering insight in the relative importance that these segments give to various housing attributes. The findings demonstrate advantages over a traditional, single model approach and can be helpful in formulating contemporary housing policy.
Geology of the Santiago Peak quadrangle, Texas

The U. S. Geological Survey topographic sheet of the Santiago Peak quadrangle, Texas, covering 275 square miles, includes the southwestern part of the Marathon uplift, trans-Pecos Texas, where post-Cretaceous folds of the Santiago Mountains cross Paleozoic structural trends. Paleozoic sediments deposited in the Llanoria geosyncline aggregate 15,000 feet and were deformed in Pennsylvanian time by orogenic movements directed from the southeast. The Cretaceous sea, which advanced over beveled Paleozoic strata, deposited 2500 feet of sediments, mostly limestones. The Glen Rose limestone is the oldest Cretaceous formation. The Maxon sandstone may be Fredericksburg in age. The Devils River limestone is divided into four members, two of which can be correlated, at least in part, with the Edwards and the Georgetown formations of central Texas. The Aguja is the youngest Cretaceous formation. Post-Cretaceous doming of the Marathon uplift did not extend west of the Santiago Mountains, in which the chief structural feature is a monocline of Cretaceous strata with the limb overturned to the west. In places the lower flexure of the monocline is broken by a thrust fault, with thrusting from the east. The folding and faulting are believed to have been related to orogeny in the Sierra Madre Oriental 100 miles to the southwest. Large normal faults, trending north-south and northwest-southeast, produced blocks now tilted westward. Post-Cretaceous sills of alkalic syenite occur west of Santiago Mountains.
Clostridium difficile and its toxin in healthy neonates.

The results were analysed according to the method of feeding, delivery, length of ruptured membranes before delivery, and the ward in which the babies were nursed until their discharge home. A limited environmental survey was performed on one of the wards. The floor of the nurseries, pieces of equipment, and bed pan macerator were sampled with moistened swabs, which were then incubated in cooked meat broth and subcultitred on to C difficile agar. Finger impressions from staff were taken directly on to C difficile agar. The results (table) showed an increase in the carrier rate of C difficile in the stools of healthy babies in the first 28 days of life. By the end of the fourth week nearly half were colonised. There were no significant differences between breast fed and bottle fed babies; between those born by normal delivery, instrumental delivery (forceps or breech), or caesarean section; or between those born after short rupture of membranes (0-4 hours) and long rupture of the membranes (4-20 hours). There was, however, a significant clustering of positive cases in one of the postnatal wards (ward A) compared with the other two (p < 0-05 by the Fisher exact probability test for samples I and 2, but no significant difference for sample 3).
State of the Art Review Reverse shoulder arthroplasty: State-of-the-art

The reverse shoulder arthroplasty conceived by Paul Grammont in 1985 has gradually gained popularity as a treatment for multiple shoulder diseases. Unlike previous reverse shoulder prosthesis characterized by unsatisfactory results and a high glenoid implant failure rate, the Grammont design has immediately shown good clinical outcomes. This semi constrained prosthesis solved the issues of the very ﬁ rst designs by medializing and distalizing the center of rotation with an increased stability of the replacement of the component. The indication was initially limited to cuff tear arthropathy (CTA). It has then been expanded to irreparable massive cuff tears and displaced humeral head fractures. The most frequent problems of this design are a limited postoperative external rotation and scapular notching. Different modi ﬁ cations to the original Grammont design have been proposed with the aim of decreasing the risk of failure and complications and improving the clinical outcomes. Both the position and version/inclination of the glenosphere and the humeral con ﬁ guration (e.g. neck shaft angle) in ﬂ uence the RSA outcomes. A lateralized glenoid (whether with bone or metal) and a 135 (cid:1) Inlay system con ﬁ guration leads to a moment arm which is the closest to the native shoulder. Clinical research will focus on implant designs reducing bone adaptations and revision rate, strategies to prevent more effectively infections. Furthermore, there is still room for improvement in terms of better postoperative internal and external rotations and clinical outcomes after RSA implanted for humeral fracture and revision shoulder arthroplasty.

Personalized Context-Aware Smartphone Usage Forecasting: A Machine Learning Model

- In the past few decades, the field of human activity recognition has experienced significant growth. Numerous techniques for gathering data and evaluating it to find activity have been thoroughly researched. Contextual information pertinent to users' varied phone usage activities is captured through the device logs as a result of the growing popularity of recent enhanced features and context awareness in smart mobile phones. Context-aware customized systems may be created by simulating and forecasting how people will use their smartphones in different situations, such as temporal, geographical, or social information. In order to perform a context-aware analysis, we begin by applying five well-known machine learning methods for classifying data. We then present empirical assessments of an artificial neural network-based classification model, which is frequently used in deep learning, and perform a comparative analysis. A number of experiments are run on real mobile phone datasets gathered from users individually in order to evaluate the efficacy of these classifier-based context-aware models. Intuitive context-aware systems for smartphone users may be designed and built with the aid of the overall experimental findings and debates, which can be helpful to both researchers and application developers.
THE CASE OF TOURISM VERSUS TERRITORY CONFLICT

Conflict occurs when the parties involved have divergent interests. spatial planning involves a high number of agents who have conflicting characteristics (public/ private, central/local government, the economy/environment) and divergent objectives or interests, and therefore, face the challenge of managing conflicts that are particularly difficult to resolve. a conflict management process that seeks to promote joint and constructive action amongst the stakeholders, and arrive at mutually beneficial solutions, requires a collaborative approach. in such an approach, leadership takes on a fundamental role. in this context, proceeding from a review of the literature on collaborative leadership, the aim of this paper is to answer the following question: what are the main leadership characteristics and functions that are necessary to carry out a collaborative conflict management process? in order to arrive to a conclusion, a tourism vs. territory conflict study was carried out, in which 26 public and private stakeholders were interviewed. These people are responsible for policies and interventions that have an impact on a territory that is subject to a high tourist development pressure and, at the same time, retains a high degree of natural value, in which the existence of intractable conflicts is a constant, namely the troia -Melides coastal region in Portugal. The results of this empirical research confirm the idea that implementing a collaborative process in Portugal is only possible if there is a leadership that has authority, legitimacy, impartiality, neutrality and the necessary communication and mobilization skills to involve the stakeholders in the process.
