Brief Review of Photocatalysis and Photoresponse Properties of ZnO–Graphene Nanocomposites

As a typical wide bandgap semiconductor, ZnO has received a great deal of attention from researchers because of its strong physicochemical characteristics. During the past few years, great progress has been made in the optoelectronic applications of ZnO, particularly in the photocatalysis and photodetection fields. To enable further improvements in the material’s optoelectronic performance, construction of a variety of ZnO-based composite structures will be essential. In this paper, we review recent progress in the growth of different ZnO–graphene nanocomposite structures. The related band structures and photocatalysis and photoresponse properties of these nanocomposites are discussed. Additionally, specific examples of the materials are included to provide an insight into the common general physical properties and carrier transport characteristics involved in these unique nanocomposite structures. Finally, further directions for the development of ZnO–graphene nanocomposite materials are forecasted.

Measuring the International Mobility of Inventors: A New Database

This paper has two objectives. First, it describes a new database mapping migratory patterns of inventors, extracted from information included in patent applications filed under the Patent Cooperation Treaty. We explain in detail the information contained in the database and discuss the usefulness and reliability of the underlying data. Second, the paper provides a descriptive overview of inventor migration patterns, based on the information contained in the newly constructed database. Among the largest receiving countries, we find that the United States exhibits by far the highest inventor immigration rate, followed by Australia and Canada. European countries lag behind in attracting inventive talent; in addition, France, Germany, and the UK see more inventors emigrating than immigrating. In relation to the number of home country inventors, Central American, Caribbean and African economies show the largest inventor brain drain.
THE EFFECT OF PHENOLIC, ALKALOID AND TERPENOID EXTRACTS OF ARTIMISIA VULGARIS ON THE NON-CUMULATIVE MORTALITY OF LARVAL INSTARS OF THE CULEXQUINQUEFASCIATUS MOSQUITO

The purpose of this study was to determine the efficacy of phenolic, alkaloid, and crude terpene extracts of wormwoodArtimisia vulgaris leaves on non-cumulative mortality of larval instars of Culexquinquefasciatus mosquito. Under laboratory conditions at 30±1°C and a relative humidity of 65±5. The results of the present study showed a significant increase (P<0.05) in the mortality rates of larval instars treated with concentrations (100, 250, 500, 1000, 1500, 2000ppm) of extracts of phenolic alkaloids and crude terpenoids of wormwood leaves. The first larval instar was more sensitive than the other larval stages to all
Multi-level dynamics of a simulated agent system

Simulated multi-agent football provides a good test-bed to study the properties and dynamics of multi-level systems. A single player can be considered as the basic building block of the system, then groups of players form structures which can be considered to exit at a higher level than the players themselves. Structures have properties that single players do not, such as being strategically good. This paper presents a network based approach to represent and study the properties and dynamics of multi-level systems. In this paper the elements of a system (i.e. football agents, ball and goals) are represented by network nodes and their interactions as edges. A fundamental idea in this paper is that interconnected nodes are considered as new constructs that exist one level above the elements and interactions that de¯ne them. This assembly of networks into higher-level constructs leads into a multi-level representation of the simulated football system.
The Tax Consequences of Share Repurchases and Other Non-Dividend Cash Payments to Equity Owners

The financial behavior of corporations has changed greatly in the last ten years. Previously, most of the cash that stockholders received from cor porations took the form of dividends, and the dividend cash flow was the ultimate determinant of the value of equities. Recently, as this paper will document, dividends have been surpassed by nondividend cash dis tributions to shareholders. These distributions are the sum of share

Spasticity evaluation through physiological feedback system model identification

The quantitative and objective evaluation of spasticity has been desired by the clinical staff in rehabilitation and orthopaedics where subjective evaluations such as modified Ashworth scale (MAS) were mostly used. There have been a lot of studies for the evaluation of spasticity, but only few of them suggested quantitative evaluation with doubtful practicality for use in clinic. Data from the simple pendulum test can be used for quantitative evaluation of the spasticity with the help of biomechanical modeling. The spasticity of a knee joint can be modeled as nonlinear feedback of muscle lengthening velocity and the muscle length. Through the optimization of the modeling error, the feedback parameters can be determined which can be used as the quantitative evaluation criteria of the spasticity. This paper shows the principle and the clinical possibility of the method.
Vigilance Enhancement Using Computerized Techniques

This paper presents a review on vigilance enhancement using computerized means and discusses their contradictory findings. It highlights the key differences between research findings and argues that variations in experimental protocol could be a significant contributing factor to the controversial results. In this paper, we found that, computerized means of enhancement are reliable and have significant effects on reducing vigilance decrement. The paper discusses the challenges toward the enhancement techniques and suggests several alternative strategies to reduce vigilance decrement. Furthermore, this review provides evidence to use computerized means of enhancement on vigilance studies, regardless of their practical challenges.
Restoring hearing and balance in a mouse model of SLC26A4-related deafness

Mutations of SLC26A4 are the most common cause of the hearing loss associated with enlargement of the vestibular aqueduct. SLC26A4 encodes pendrin, an anion exchanger expressed in the cochlea, the vestibular labyrinth, and the endolymphatic sac of the inner ear. Slc26a4 mice, devoid of pendrin expression, develop an enlarged membranous labyrinth which leads to the failure to develop hearing, thereby recapitulating the human disease. Identifying the ionic composition of the endolymph and evaluating the importance of pendrin expression at various sites are initial steps towards developing strategies for preventing enlargement of the endolymph volume and subsequently restoring the inner ear functions. The major aims of the present study are 1) To determine the ionic composition of inner ear fluids during the developmental phase in which the enlargement of the endolymph volume occurs; 2) To test the hypothesis that pendrin expression in the endolymphatic sac is more important than its expression in the cochlea and the vestibular labyrinth. Here, we determined the Na and K concentrations in the cochlea and the endolymphatic sac with double-barreled ion-selective electrodes and generated a mouse model that restores pendrin expression in the endolymphatic sac while lacking expression in the cochlea and the vestibular labyrinth. High Na and low K concentrations were found in the cochlear endolymph during the embryonic stage. A rise of the K concentration along with a decline of the Na concentration occurred shortly before birth. The site-specific restoration of pendrin to the endolymphatic sac prevented enlargement and rescued hearing and balance. In conclusion, these data demonstrate that endolymph, in the phase of luminal enlargement during the embryonic development, is a Na-rich fluid that is modified into a K-rich fluid just before birth; restoration of pendrin in the endolymphatic sac is sufficient for developing normal inner ear function. Furthermore, these data suggest enlargement of endolymph volume caused by the loss of Slc26a4 is a consequence of disrupted Na absorption. Moreover, pharmacological strategies that correct fluid transport, as well as spatially and temporally limited restorations of pendrin, might restore normal inner ear functions in humans carrying mutations of SLC26A4.

Role of Human Papillomavirus and Its Association With an Indian OSCC Subjects

Oral Cancer; especially Oral Squamous Cell Carcinoma (OSCC) is the eighth most common cancer all over the globe and most common neoplasm in India. Due to the tobacco addiction pattern in Indians specially Guajarati’s are well known for high consumption of tobacco in non-smoking form may have the high-risk for developing oral cancer. Apart of this, Human papilloma virus(HPV) might be one of the cause for developing oral cancer hence, the proposed study was carried out for 50 primary OSCC subjects from January 2018 to October 2018. Tumour specimens were HPV-genotyped by type specific PCR method. Statistical analyses were performed by Fisher’s exact test. The present study identified 4% HPV infection frequency in advanced staged OSCC Indian subset, where One OSCC stage IV patient observed with HPV 16 infection and one OSCC stage III patient with HPV 18. Our finding differs with rest of the population, as the region have high amount of consumption of tobacco. Current study need to be validated in larger sample size to get the clear view for association of HPV with oral cancer.
Sound Visualization Using Typography Composition Based GIF

Visual communication design is a creative communication process, in which it combines art to encode and decode the message. As the technology advances, visual design communication explore further, paving ways to visualize something that doesn't have the visual attribute; sound, something that can only be perceived through auditory senses. The sound is transformed by controlling symbols, images, color & movement into an image, using a visual programming software combined with typography composition, to create GIF (Graphic Interchange Format) as the final product. Sound visualization opens the possibility to experience sounds without even hearing it. It is an experimental tool to experience sound, to give an even deeper meaning of a message, and to bridge the possibilities to convey sound to the hearing impairment, those who carry disability, expanding the minds and horizon so they can experience sound.
Structural transformations of a gas-atomized Al62.5Cu25Fe12.5 alloy during detonation spraying, spark plasma sintering and hot pressing

In this work, we traced structural transformations of an Al62.5Cu25Fe12. 5 alloy, in which a quasicrystalline icosahedral phase (i-phase) can be formed, upon spraying onto a substrate and consolidation from the powder into the bulk state. The Al62.5Cu25Fe12. 5 powder was obtained by gas atomization and consisted of i-phase and ? -phase AlCu(Fe). The powder was detonation sprayed (DS) and consolidated by spark plasma sintering (SPS)/hot pressing (HP). During DS, the particles experienced partial or complete melting and rapid solidification, which resulted in the formation of coatings of a complex structure. The composite regions containing i-phase were inherited from the powder alloy. The fraction of the material that experienced melting solidified as ? -phase AlFe(Cu) in the coating. It was suggested that the difficulty of obtaining i-phase upon post-spray annealing is related to aluminum depletion of the alloy during DS. During SPS and HP, the elemental composition of the alloy was preserved, while the exposure to an elevated temperature led to phase homogenization. SPS and HP conducted at 700? C resulted in full densification and the formation of a single-phase quasicrystalline alloy. The sintered single-phase alloy showed a higher microhardness in comparison with the DS coatings.
Regulation of virtual currencies in the United Arab Emirates: accounting for the emerging public/private distinction

ABSTRACT This article maps the changing global conversation on virtual currencies (VCs) internationally And brings that to bear on the development of a suitable regulatory framework for VCs in the United Arab Emirates (UAE). Through a review of recent international developments, the article notes a reversal in regulatory attitude towards VCs. This review suggests two emerging horizons of regulatory intervention. The first concerns the public issue of VCs to develop financial traceability and economic transparency – an arrangement that would be particularly relevant for developing countries with large informal economies. In particular, public VC issue raises follow-up questions of technological adequacy and the legal status of a means of payment guaranteed by the State. The second concerns privately issued VCs traded on independent platforms and focuses on the trade off between economic development, through a private market for VCs, and the risks connected to money laundering and the financing of terrorism. Here, a two-pronged system of ex ante licensing to private venture capitalists, coupled with ex post-sanctions, appears to be an emerging international standard for supporting economic development in countries marked by the preponderant weight of an underground economy.

Caf s are recognised as an important component of retail districts and cities more generally (Florida, 2004; Hospers & van Dalm, 2005; Jacobs, 1969), but they are rarely taken seriously as workplaces in literature about work.
A Methodology for Early Exploration of TSV Interconnects in 3D Stacked ICs

Planar scaling of semiconductor ICs for achieving higher integration seems to be on the brink of saturation. As an alternative solution, three-dimensional (3D) integration follows a more than Moore strategy in which circuit layers are stacked vertically. Although, 3D integration technology has moved from Lab to Fab, a complete supply chain is yet to fall in place. Due to the lack of a fully automated 3D IC design flow, realistic performance estimation at an early stage becomes imperative to ensure an efficient end-to-end design cycle. In this paper, an approach is shown for early performance and cost estimation of a 3D stacked IC in order to allow critical technology parameters to influence system design decisions. A novel methodology is proposed which explores Through-Silicon-Via (TSV) placement topologies for a 2-tier vertical interconnect across two performance corners of the TSV technology. It estimates electrical performance and TSV area penalty which are then translated to system design metrics. The methodology is applicable to digital ICs and offers flexibility in selection of the CMOS technology node and the 3D stacking granularity. Its implementation in SystemC efficiently achieves parameterizability and enables its integration into a high-level system simulation framework. By applying the methodology to a case of a 7-port 3D router it was found that, the most preferred TSV placement topology in terms of performance and cost is Isolated for 45 nm technology node and Shielded for 32 nm technology node.

Temperature Aware Routing Protocol in the field of Wireless Body Sensor Network

Wireless Body Sensor Network (WBSN) has come into view as a trending field in the recent years, having major application in the medical field. In this, few sensor nodes are put on or around human body which gathers the data and that data is processed for early detection of diseases where we can start early treatment, data is gathered while surgeries are performed. Based on the criticality of the information, it is very important to have routing protocols which are efficient and can be effectively used to gather the data[2]. In WBSN, one of the major concern is whenever we place sensor nodes on the human body, as they are used to gather the data, the temperature of those sensor node increases due to load and which need to be minimize in an effective way, how the packets need to be send in order to minimize the network load, energy saving mechanisms, efficient and effective packet delivery [3]. These few parameters bring the need of routing protocols into the picture. In this paper, we have critically reviewed all the routing protocols proposed so far which take temperature of the node as a metric, popularly known as Temperature-Aware Routing Protocols. We hope this help readers in their future work.
Barriers to Therapeutic Use of Hydroxyurea for Sickle Cell Disease in Nigeria: A Cross-Sectional Survey

Background: Sickle cell disease, the inherited blood disorder characterized by anemia, severe pain and other vaso-occlusive complications, acute chest syndrome, disproportionate hospitalization, and early mortality, has significant financial, social, and psychosocial impacts and drains individuals, families, and health systems globally. Hydroxyurea could improve the health of the 300,000 individuals born each year with sickle cell disease in sub-Saharan Africa; however, challenges to adoption and adherence persist. This study assessed the barriers to therapeutic use of hydroxyurea for sickle cell disease within the Nigerian healthcare system, specifically from the level of the patient, provider, and health system. Methods: We used purposive sampling to recruit participants from 13 regions in Nigeria. A cross-sectional survey was administered to physicians (n = 70), nurses or counselors (n = 17), and patients or their caregivers (n = 33) at 13 health centers. Findings were mapped onto the appropriate Consolidated Framework for Implementation Research (CFIR) domains. Results: This study was able to identify factors that mapped onto the inner setting, outer setting, and characteristics of individuals domains of CFIR. The majority of physicians (74.3%) prescribe hydroxyurea, and half stated hydroxyurea is the standard of care. Among clinicians, barriers included limited knowledge of the drug, as well as low self-efficacy to prescribe among physicians and to counsel among nurses; perceived side effects; perceived patient preference for traditional medicine; cost for patient and expense of accompanying laboratory monitoring; and limited availability of the drug and equipment for laboratory monitoring. Among patients and caregivers, barriers included lack of knowledge; perceived side effects; cost; religious beliefs of disease causation; and lack of pediatric formulation. Conclusions: Findings suggest that patient, provider, and health systems-level interventions are needed to improve hydroxyurea uptake among providers and adherence among patients with sickle cell disease in Nigeria. Interventions such as patient education, provider training, and policy change could address the disproportionate burden of sickle cell disease in sub-Saharan Africa and thus improve health equity.
