A cooperative and adaptive resource scheduling for Vehicular Cloud

A Vehicular Cloud is defined as a set of vehicles that share their computation resources in a cloud. These resources are scheduled on demand based on cooperation between vehicles and the roadside. The biggest challenge in this type of cloud is to create a structure that will manage the service and resource when the cloud does not depend on the roadside infrastructure. Thus, the vehicles need to collaborate with each other to provide services and resources through their embedded resources. To address this challenge, we propose a service scheduling that will manage the requested service and the allocation service to achieve the quality of service requirements, considering the vehicular network characteristics. Simulation results show that the proposed approach achieves a higher service ratio (approximately 95%) with a lack of service of about 5%. Furthermore, the proposed solution achieved an average of 93% when we consider the average service quality and an average of 0,6 second in the service consuming delay.
Opposite Effects of Insulin and Catecholamines on LDL-Receptor Activity in Human Mononuclear Leukocytes

The mechanisms by which insulin and catecholamines affect low-density lipoprotein (LDL)-receptor activity were studied in freshly isolated human mononuclear leukocytes. Incubation of cells for up to 24 h in a lipid-free medium resulted in an increase in the specific binding, accumulation, and degradation of 125I-labeled LDL. Insulin stimulated the ability of the cells to bind, accumulate, and degrade the lipoprotein with high affinity, which may be caused by an increase in the LDL-receptor number without altering binding affinity. (–)-Epinephrine inhibited the specific binding, accumulation, and degradation of 125I-LDL. This effect appears to be mediated by a decrease in the number of LDL receptors and not by a change in the binding affinity. (–)-Norepinephrine, the unspecific β-adrenergic agonist (–)-isoproterenol, and the β2-specific agonist terbutaline mimicked the effect of epinephrine on LDL-receptor activity. Catecholamines and β-adrenergic agonists yielded sigmoidal log-concentration effect curves. The action of epinephrine was attenuated by the β-antagonist (dl)-propranolol. These results demonstrate that insulin stimulates and catecholamines suppress the specific binding, accumulation, and degradation of 125I-LDL in human mononuclear leukocytes. The catecholamine action appears to be mediated by β2-adrenergic receptors. A suppression of LDL-receptor activity resulting from deficiency of insulin and elevated plasma catecholamine concentrations in uncontrolled insulin-dependent diabetic patients may contribute to the increased levels of LDL cholesterol observed in these patients.
Automated Detection of Hypertension and Stroke by Nicking Quantification in Retinal Images

Retinal blood vessels morphology have been shown to be highly related to the risk of cardiovascular diseases such as hypertension, stroke and coronary heart diseases. Measuring the width of arteries and veins shown to have good correlation with the detection of cardiovascular diseases. In this paper, the true vessels in retinal images are identified as a post processing step to segmentation. The segmented vascular structure was modeled as a vessel segment graph. The blood vessels are identified by finding the forest in the graph by using the algorithm traverse. The artery vein classification method finds the arteries and veins in the retinal images. The widths of arteries and veins are measured to find the presence of hypertension and stroke. The results are analyzed and experimented with respect to actual measurements of vessel morphology. The results shows that the proposed approach is able to achieve 98.9% pixel precision and 98.7% recall of the true vessels for clean segmented retinal images, and remains robust even when the segmented image is noisy.
Current and future perspectives on intracytoplasmic sperm injection : a critical commentary Introduction

Intracytoplasmic sperm injection (ICSI) is an increasingly popular means of treating infertility in couples who wish to conceive. However, there are many potential complications that can be faced by the clinician while performing ICSI. These complications and other related issues are discussed, with an emphasis on understanding how these issues are being resolved, or how they can be resolved in the future. Matters of sperm selection and injection are discussed, as well as the effect of ICSI on fertilization, embryonic growth and development, and the health of ICSI-conceived children. These aspects are viewed from various perspectives, including genetic, mechanistic, developmental and clinical. Since new studies on ICSI are published regularly, it is important that the established protocol is revised often, and that the role of ICSI in infertility therapy is continually re-evaluated.
On the turbulence structure in inert and reacting compressible mixing layers

Direct numerical simulation is used to investigate effects of heat release and compressibility on mixing-layer turbulence during a period of self-similarity. Temporally evolving mixing layers are analysed at convective Mach numbers between 0.15 and 1.1 and in a Reynolds number range of 15000 to 35000 based on vorticity thickness. The turbulence inhibiting effects of heat release are traced back to mean density variations using an analysis of the fluctuating pressure field based on a Green's function.
Two-dimensional dense-arrayed probe-cards with a hoe-shaped probing-tip micromachining technique

Presented is a MEMS probe-card with ultra dense two dimensional (2-D) probe arrays for wafer-level IC test. About 110000 probe tips can be simultaneously fabricated in a 4-inch wafer, with the 2-D tip pitch as 240 mum times 160 mum. The "hoe-shaped" microprobe structure is composed of one or two planar arms and an up-tilted tip, both of which are high-yield fabricated by metal micromachining techniques including electroplating. The measured spring constants for all the three types of designed probes agree well with the designed values. As both mechanical and electrical interconnections, the Sn/Ag solder-bumps feature excellent properties. The tested contact resistance values are always below 0.8Omega, while the current leakage between two adjacent probes is only 150 pA under 3.3 V.
Performance test parameters of remote sensing for identification burned area using Landsat-8

Landsat 8 satellite is a natural resource that is characterized by having continuity and consistency in analyzing observations of terrestrial changes in the past and the future in a time series and has modified the value of spatial resolution, spectral, temporal, and radiometric, so as to provide a number of opportunities utilization, such as identifying disaster forest fires. Forest as authorized and living resources, appropriately guarded sustainability of unbridled exploitation. Conversion of forest to cultivation, mining, agriculture in a way that does not sound environmental wisdom, such as burning of land, will face a lack of continuity and succession of tempests plant growth and the increasing amount of burnt area mapping carbon. Accurate assessment is needed to calculate the amount of biomass, for it parameters need to detect, reduce ambiguity, and reliably discriminate burned areas. This study aims to obtain the best models parameters for burned areas using Landsat 8, the results show NBR gave the best results compared to other parameters.
Modified linear projection for large spatial datasets

ABSTRACT Recent developments in engineering techniques for spatial data collection such as geographic information systems have resulted in an increasing need for methods to analyze large spatial datasets. These sorts of datasets can be found in various fields of the natural and social sciences. However, model fitting and spatial prediction using these large spatial datasets are impractically time-consuming, because of the necessary matrix inversions. Various methods have been developed to deal with this problem, including a reduced rank approach and a sparse matrix approximation. In this article, we propose a modification to an existing reduced rank approach to capture both the large- and small-scale spatial variations effectively. We have used simulated examples and an empirical data analysis to demonstrate that our proposed approach consistently performs well when compared with other methods. In particular, the performance of our new method does not depend on the dependence properties of the spatial covariance functions.

Toward Better Training in Peer Assessment: Does Calibration Help?

For peer assessments to be helpful, student reviewers need to submit reviews of good quality. This requires certain training or guidance from teaching staff, lest reviewers read each other’s work uncritically, and assign good scores but offer few suggestions. One approach to improving the review quality is calibration. Calibration refers to comparing students’ individual reviews to a standard—usually a review done by teaching staff on the same reviewed artifact. In this paper, we categorize two modes of calibration for peer assessment and discuss our experience with both of them in a pilot study with Expertiza system.
Perioperative Outcomes after Unilateral and Bilateral Total Knee Arthroplasty

Background:The safety of bilateral total knee arthroplasties (BTKAs) during the same hospitalization remains controversial. The authors sought to study differences in perioperative outcomes between unilateral and BTKA and to further compare BTKAs performed during the same versus different operations during the same hospitalization. Methods:Nationwide Inpatient Sample data from 1998 to 2006 were analyzed. Entries for unilateral and BTKA procedures performed on the same day (simultaneous) and separate days (staged) during the same hospitalization were identified. Patient and healthcare system–related demographics were determined. The incidences of in-hospital mortality and procedure-related complications were estimated and compared between groups. Multivariate regression was used to identify independent risk factors for morbidity and mortality. Results:Despite younger average age and lower comorbidity burden, procedure-related complications and in-hospital mortality were more frequent after BTKA than after unilateral procedures (9.45% vs. 7.07% and 0.30% vs. 0.14%; P < 0.0001 each). An increased rate of complications was associated with a staged versus simultaneous approach with no difference in mortality (10.30% vs. 9.15%; P < 0.0001 and 0.29% vs. 0.26%; P = 0.2875). Independent predictors for in-hospital mortality included BTKA (simultaneous: odds ratio, 2.23 [95% confidence interval, 1.69–2.95]; P < 0.0001; staged: odds ratio, 2.01 [confidence interval, 1.28–3.41]; P = 0.0031), male sex (odds ratio, 2.02 [confidence interval, 1.75–2.34]; P < 0.0001), age older than 75 yr (odds ratio, 3.96 [confidence interval, 2.77–5.66]; P < 0.0001), and the presence of a number of comorbidities and complications. Conclusion:BTKAs carry increased risk of perioperative morbidity and mortality compared with unilateral procedures. Staging BTKA procedures during the same hospitalization offers no mortality benefit and may even expose patients to increased morbidity.
A novel method of obtaining near real-time observations of phytoplankton from a mobile autonomous platform

Emerging marine observation technologies provide new opportunities to learn about phytoplankton communities with greater spatiotemporal resolution. Autonomous vehicles enable real-time ocean data collection and communications over long durations, in varying sea states and at lower cost than crewed ships. The Jupiter Research Foundation is developing a novel device to obtain near real-time phytoplankton observations from a mobile unmanned platform. The Jupiter Autonomous Microscope (JAM) is an autonomous microscope imaging system that acquires, crops and geo-tags phytoplankton images and sends them to a shore-based server via mobile phone or satellite networks. On-shore processing includes automated object measurements and classification, as well as statistical calculations. Images and corresponding data are made accessible on a dedicated website that allows filtering, annotation and sharing. Successfully deployed on Wave Gliders for several weeks at a time, JAM provides a unique view of phytoplankton community structure. This paper describes the overall JAM design and operation.
THE EXCAVATIONS AT TELL CHAGAR BAZAR AND AN ARCHAEOLOGICAL SURVEY OF THE HABUR REGION 1934–5. By M. E. L. Mallowan. Oxford University Press 1936. pp. 59, 29 figs., 3 pls. (Reprinted from Iraq,III, partI). 10s 6d.

excavations of Uruk and Jemdet Nasr which have given their name to two preceding civilizations characterized by their associated pottery ; and finally the excavations of Tell Asmar and Khafaje in the Baghdad region, principally famous for their richness in remains of the early dynastic period. These discoveries are also dealt with in a special chapter, in the light of subsidiary excavations rich in pottery typical of the main sites, thus enabling a system of relative chronology to be established. The author recalls that Sir Leonard Woolley puts the beginning of the Royal Tombs a little after 3500 B.C. and the dynasty of Ur at 3100 B.c., whilst Mr Frankfort places the latter at about 2900 B.C. To the archaic historical period belong religious buildings whose plans belong to two types ; the northern type, whose entrance is in a side of the building, and the southern type where it is in its longer axis. The study of these tombs leads naturally to a description of the Royal Tombs of Ur which seem to find their analogue, so far as the practice of human sacrifice is concerned, in the oldest parts of the Y cemetery at Kish. Statuary is carefully portrayed and studied in the concluding portion of the book. Of the Akkadian period, whose structural peculiarities are described (palace of Tell Asmar), we may select for mention an admirable bronze head from Nineveh representing perhaps a monarch of the dynasty of Agade. The book is written in a good clear style and provides an accurate and useful summary of recent discoveries in Mesopotamia. G. CONTENAU.
The challenge of energy retrofitting the residential housing stock: grassroots innovations and socio-technical system change in Worcester, MA

This paper addresses an intractable problem: how to energy-upgrade the existing residential housing stock on a large scale, potentially saving up to 30% of all greenhouse gas emissions? The paper focuses on the USA, with a case study in Worcester, Massachusetts. To address this problem we conceptualise the residential housing stock as a socio-technical system, with as main elements technology, professional knowledge and know-how, formal institutions, markets and the key actors within each. The analysis demonstrates the interconnectedness of the elements and sub-elements of the system, the need to affect change in all of them, identifies homeowners (consumers) and local authorities as the most difficult to change, and suggests that both technological and social innovation – including grassroots activism and multistakeholder collaboration – is needed. We conceptualise housing retrofitting projects as small-scale niche experiments and as grassroots innovations. In this paper we describe an experiment in Worcester, Massachusetts, in which the vision of the project – as community development – was produced by a coalition (WoHEC) of many local actors. This project illustrates both the potentials of our proposed framework in terms of grassroots innovations and socio-technical experiments and its limitations: learning among stakeholders is often slow and ineffective. More research is needed to refine the conceptual framework and to make it applicable to both grassroots innovations and municipal projects.
ZnO Nanorods Arrays and Heterostructures for the High Sensitive UV Photodetection

In the field of semiconductor nanostructures, one–dimensional (1D) ZnO nanostructures (e.g. Nanowires, nanorods, nanobelts) are the most promising candidates due to their important physical properties and application prospects. Large surface–to–volume ratio and direct carrier conduction path of 1D ZnO nanostructures are the key factors for getting edge over other types of nanostructures. ZnO is a direct wide band gap materials having bandgap of ~3.37 eV and high excitonic binding energy, 60 meV at room temperature. 1D ZnO nanostructures are extensively studied for their applications in various electronic and optoelectronic devices, e.g., field effect transistors, ultra violet (UV) photodetectors, UV light emitting diodes, UV nanolaser, field emitter, solar cells etc. (Huang et al., 2001a; Liao et al., 2007; Li et al., 2005; Kind et al., 2002; Soci et al., 2007; Alvi et al., 2010; Liu et al., 2009; Law et al., 2005; Law et al., 2006; Yeong et al., 2007; Xu et al., 2010; Gargas et al., 2009) Various types of ZnO nanorods (NRs) have been grown by several groups worldwide (Huang et al., 2001b; Wei et al., 2010; Ahn et al., 2004; Li et al., 2008; Dhara & Giri, 2011c; Chen et al., 2010; Giri et al., 2010) and they studied the effect of growth conditions on the morphology of the ZnO NRs. The surface of the nanostructures has crucial role in determining the electrical and optoelectronic properties of nano-devices. As the surface-to-volume ratio in NRs is very high, the surface states also play a key role on optical absorption, luminescence, photodetection and other properties. Thus, nanoscale electronic devices have the potential to achieve higher sensitivity and faster response than the bulk material.

Modelling human emotion in interactive environments: Physiological ensemble and grounded approaches for synthetic agents

With the rising research in emotionally believable agents, several advances in agent technology have been made, ranging from interactive virtual agents to emotional mechanism simulations and emotional agent architectures. However, creating an emotionally believable agent capable of emotional thought is still largely out of reach. It has been proposed that being able to accurately model human emotion would allow agents to mimic human behaviour while these models are studied to create more accurate theoretical models. In light of these challenges, we present a general method for human emotional state modelling in interactive environments. The proposed method employs a three-layered classification process to model the arousal and valence (i.e., hedonic) emotional components, based on four selected psychophysiological metrics. Additionally, we also developed a simplified version of our system for use in real-time systems and low-fidelity applications. The modelled emotional states by both approaches compared favourably with a manual approach following the current best practices reported in the literature while also improving on its predictive ability. The obtained results indicate we are able to accurately predict human emotional states, both in offline and online scenarios with varying levels of granularity; thus, providing a transversal method for modelling and reproducing human emotional profiles.
Modulating cortico‐striatal and thalamo‐cortical functional connectivity with transcranial direct current stimulation

Transcranial direct current stimulation (tDCS) is a noninvasive brain stimulation technique that has been shown to alter cortical excitability and activity via application of weak direct currents. Beyond intracortical effects, functional imaging as well as behavioral studies are suggesting additional tDCS‐driven alterations of subcortical areas, however, direct evidence for such effects is scarce. We aimed to investigate the impact of tDCS on cortico‐subcortical functional networks by seed functional connectivity analysis of different striatal and thalamic regions to prove tDCS‐induced alterations of the cortico‐striato‐thalamic circuit. fMRI resting state data sets were acquired immediately before and after 10 min of bipolar tDCS during rest, with the anode/cathode placed over the left primary motor cortex (M1) and the cathode/anode over the contralateral frontopolar cortex. To control for possible placebo effects, an additional sham stimulation session was carried out. Functional coupling between the left thalamus and the ipsilateral primary motor cortex (M1) significantly increased following anodal stimulation over M1. Additionally, functional connectivity between the left caudate nucleus and parietal association cortices was significantly strengthened. In contrast, cathodal tDCS over M1 decreased functional coupling between left M1 and contralateral putamen. In summary, in this study, we show for the first time that tDCS modulates functional connectivity of cortico‐striatal and thalamo‐cortical circuits. Here we highlight that anodal tDCS over M1 is capable of modulating elements of the cortico‐striato‐thalamo‐cortical functional motor circuit.
