A 6–18 GHz GaN distributed power amplifier using reactive matching technique and simplified bias network

Two-stage reactively matched gain cells are applied to design a high-gain multi-octave distributed power amplifier (DPA) in this paper. The proposed reactively matched distributed amplifier (RMDA) structure shows a high gain and high output power performance within a small die size. The DC bias network of each section is simplified to implement the proposed structure in an MMIC and the design guide for the bias network is provided. A 6–18 GHz GaN DPA fabricated with the commercial 0.25-µm GaN HEMT process shows output power reaching 40.3–43.9 dBm with 16–27% PAE. To the best of our knowledge, this is the first demonstration of a GaN DPA using reactively matched gain cells, and it exhibits excellent small-signal gain and RF power performance capabilities among other reported GaN PAs with a multi-octave bandwidth up to the Ku-band.
Incidence of Sarcoptes scabiei (Acari: Sarcoptidae) and Haematopinus suis (Anoplura: Haematopinidae) on swine in Indiana.

A survey was conducted during 1980 and 1981 to determine seasonal incidence of hog lice, Haematopinus suis (L.), and sarcoptic mange mites, Sarcoptes scabiei (De Geer), in market-weight swine in Indiana. The survey indicated that infestations of both lice and mites were higher during cooler months. Over the course of the survey, hog lice and mange (itch) mites were present on 18.1 and 25.3% of all animals examined, respectively. Animals confined in small pastures had higher incidences of lice than animals in totally or partially confined systems, although confinement type did not affect incidence of mite infestation. Results of a questionnaire sent to Indiana veterinarians concerning these pests are discussed. Responding veterinarians estimated a 51.5% incidence of hog lice and 36.2% incidence of sarcoptic mange mites on farms visited. Veterinarians did not notice correlations between lice or mange and confinement type, animal breed and age, or geographical area. Results of questions asking the veterinarians treatment methods preferred and importance of these parasites are presented.
Morphologic integration of hilar ectopic granule cells into dentate gyrus circuitry in the pilocarpine model of temporal lobe epilepsy

After pilocarpine‐induced status epilepticus, many granule cells born into the postseizure environment migrate aberrantly into the dentate hilus. Hilar ectopic granule cells (HEGCs) are hyperexcitable and may therefore increase circuit excitability. This study determined the distribution of their axons and dendrites. HEGCs and normotopic granule cells were filled with biocytin during whole‐cell patch clamp recording in hippocampal slices from pilocarpine‐treated rats. The apical dendrite of 86% of the biocytin‐labeled HEGCs extended to the outer edge of the dentate molecular layer. The total length and branching of HEGC apical dendrites that penetrated the molecular layer were significantly reduced compared with apical dendrites of normotopic granule cells. HEGCs were much more likely to have a hilar basal dendrite than normotopic granule cells. They were about as likely as normotopic granule cells to project to CA3 pyramidal cells within the slice, but were much more likely to send at least one recurrent mossy fiber into the molecular layer. HEGCs with burst capability had less well‐branched apical dendrites than nonbursting HEGCs, their dendrites were more likely to be confined to the hilus, and some exhibited dendritic features similar to those of immature granule cells. HEGCs thus have many paths along which to receive synchronized activity from normotopic granule cells and to transmit their own hyperactivity to both normotopic granule cells and CA3 pyramidal cells. They may therefore contribute to the highly interconnected granule cell hubs that have been proposed as crucial to development of a hyperexcitable, potentially seizure‐prone circuit. J. Comp.

Cloning, characterization, and expression of human LIG1.

Growth factor receptors are frequently amplified and over-expressed in various human cancers. Recently, a Drosophila cell surface protein, Kekkon-1, was found to participate in an epidermal growth factor (EGF) driven negative feedback loop. Kekkon-1 is induced by EGF, binds to the EGF-receptor, and inhibits receptor-mediated signaling. Here, we have searched for human genes with homologies to Kekkon-1 and identified human LIG1. The gene is the human homologue of mouse Lig-1 and is located on chromosome band 3p14, a region frequently deleted in various human cancers. It is predicted to encode a transmembrane cell-surface protein with extracellular leucine-rich repeats and immunoglobulin-like domains. LIG1 mRNA was detected in all tissues analyzed. The highest and lowest relative expression levels were found in brain and spleen, respectively, and differed by more than 200-fold. Taken together, our data are compatible with a role for LIG1 as a growth and tumor suppressor in human tissues.
Optically Controlled Reconfigurable Antenna Array for mm-Wave Applications

This letter reports the concept and development of the first optically controlled reconfigurable antenna for millimeter-wave (mm-wave) applications. It is based on a slotted-waveguide antenna array and two photoconductive switches, which are used to control the slot electrical length. This novel photonics-based reconfigurable strategy enables frequency tunability and radiation pattern reconfiguration through the 28- and 38-GHz frequency bands. Numerical simulations and experimental results illustrate its applicability for mm-wave indoor applications. The measured gain is approximately 8.0 and 9.0 dBi at 28 and 38 GHz, respectively.
Screening humans for degrees of attractiveness of mosquitoes.

Human populations have been studied for variability in attractiveness to mosquitoes [Aedes aegypti var. queenslandensis (Theobald)]. Attractiveness or its lack was quantitated in 2 ways: 1) by subjecting individuals to mosquito bites, and 2) by recording the time when 50% of exposed mosquitoes would probe on the bottom of a cage held over the forearm. This measurement we called probing time (PT50). With the biting technique 1 individual of 838 persons tested was found resistant to the bite of the mosquito. Persons highly attractive to mosquitoes could not be identified with this biting technique. With the technique of PT50, 6 persons were found very unattractive to mosquitoes and 3 highly attractive out of 100 other individuals tested. These individuals were each retested with 100 PT50 determinations after a lapse of 2–3 weeks. Three persons were confirmed as highly unattractive and 1 as very attractive. It was found that the same mosquitoes could be used for at least 100 PT50 determinations, making this a quick and reliable technique to establish individual differences in attractiveness to mosquitoes.
Demographic profile and pregnancy outcomes of adolescents and older mothers in Saudi Arabia: analysis from Riyadh Mother (RAHMA) and Baby cohort study

Objectives To investigate the impact of maternal age on pregnancy outcomes with special emphasis on adolescents and older mothers and to investigate the differences in demographic profile between adolescents and older mothers. Methods This study is a secondary analysis of pregnancy outcomes of women in Riyadh Mother and Baby cohort study according to maternal age. The study population was grouped according to maternal age into five subgroups; <20, 20–29, 30–34, 35–39 and 40+years. The age group 20–29 years was considered as a reference group. Investigation of maternal age impact on maternal and neonatal outcomes was conducted with adjustment of confounders using regression models. Results All mothers were married when conceived with the index pregnancy. Young mothers were less likely to be illiterate, more likely to achieve higher education and be employed compared with mothers ≥ 40 years. Compared with the reference group, adolescents were more likely to have vaginal delivery (and least likely to deliver by caesarean section (CS); OR=0.6, 95% CI 0.4 to 0.9, while women ≥40 years, were more likely to deliver by CS; OR 2.9, 95% CI 2.3 to 3.7. Maternal age was a risk factor for gestational diabetes in women ≥40 years; OR 1.7, 95% CI 1.3 to 2.1. Adolescents had increased risk of preterm delivery; OR 1.5, 95% CI 1.1 to 2.1 and women ≥40 years had similar risk; OR, 1.3, 95% CI 1.1 to 1.6. Conclusion Adverse pregnancy outcomes show a continuum with the advancement of maternal age. Adolescents mother are more likely to have vaginal delivery; however, they are at increased risk of preterm delivery. Advanced maternal age is associated with increased risk of preterm delivery, gestational diabetes and CS.
Determinants of Selecting Malaria Treatment in Rural Zimbabwe: Case Study from Mutema Rural Area

This study examines the determinants of selecting malaria treatment in rural Zimbabwe, using a case study from Mutema, a rural area which is located in the eastern part of Zimbabwe in the Chipinge District. The study uses cross sectional data collected in the period between August 2009 and February 2010. The eight villages were used as clusters. The systematic random sampling was done in each cluster and a sample of 163 households was assessed. The study mainly focuses on the role played by distance to health centre, religion, education and age in inﬂuencing the choice of malaria treatment. Using a probit model, with the dependent variable being the choice of treating malaria, that is either choosing medical or self-care, ﬁve factors were found to be signiﬁcant in determining the selection of malaria treatment by malaria-infected persons. These factors are the following: distance to the nearest health centre, household attained education, religion, severity of the disease and previous infection. More importantly, distance and religion with predicted probabilities of 20% and 98%, respectively, were found to be two of the prohibiting factors for people to use medical care. There is need for policy makers to implement policy measures that aim at increasing the number of health centres in rural areas to shorten the long distance people walk in order to get access to health facilities. The positive between by the predicted probabilities for sub categories of 0.3612, 0.1244, 0.0255 and representing no education, primary education, secondary education and tertiary education categories respectively. The probabilities depict the concept that people get more educated the probability of also These are in support of the ﬁndings by which that is positively to for
Computer Security and Ethics

Today there is a great concern among businesses and individuals about privacy and security while using computers and the Internet. The two topics, privacy and security, are closely related in the computer-industry and on the Internet and there are many questions that overlap each other. Secure communication is in many cases a requirement assuring privacy and security for businesses and individuals. One of the security techniques used in communication is data encryption, which prevents unwanted users to gain access of the information that is transmitted between computer networks or on the Internet. We will in this paper, among other things, look on the technique of encrypting data, authentication of users in network systems and on the ethical questions concerning privacy and security in computer networks.
Impact of New Standard “IFRS 16 Leases” on Statement of Financial Position and Key Ratios: A Case Study on an Airline Company in Turkey

The studies regarding the changes made related to the accounting for lease have taken its final status with the publication of IFRS16 Lease Standard as a result of a long time and effort in January 2016. The related Standard shall ensure (1) the reporting of all the leases in the same way, (2) the displaying of the unrecorded leases in the financial statements and therefore, (3) the submission of more transparent, correct and comparable information. The purpose of our study is to examine the statement of financial position of the lessee enterprise after the transition to the new financial reporting standard IFRS 16 and the impacts of the change in the basic ratios. For this purpose, the impacts possible to occur in the financial position of an airline company having activities in Turkey as a result of the application of the related standard have been examined. The results of the study show that the reflection of the operating leases on the balance sheet shall cause to significant increases in the assets and liabilities and for this reason; there shall be a significant increase in the ratio of liability/asset and a significant decrease return on asset.
Estimation and allocation of insurance risk capital

Estimating tail risk measures such as Value at Risk (VaR) and Conditional Tail Expectation (CTE) is a vital component in financial and actuarial risk management. The CTE is a preferred risk measure, due to coherence and a widespread acceptance in actuarial community. In particular we focus on the estimation of the CTE using both parametric and nonparametric approaches. In parametric case the conditional tail expectation and variance are analytically derived for the exponential distribution family and its transformed distributions. For small i.i. d. samples the exact bootstrap (EB) and the influence function are used as nonparametric methods in estimating the bias and the the variance of the empirical CTE. In particular, it is shown that the bias is corrected using the bootstrap for the CTE case. In variance estimation the influence function of the bootstrapped quantile is derived, and can be used to estimate the variance of any bootstrapped L-estimator without simulations, including the VaR and the CTE, via the nonparametric delta method. An industry model are provided by applying theoretical findings on the bias and the variance of the estimated CTE. Finally a new capital allocation method is proposed. Inspired by the allocation of the solvency exchange option by Sherris (2006), this method resembles the CTE allocation in its form and properties, but has its own unique features, such as managerbased decomposition. Through a numerical example the proposed allocation is shown to fail the no undercut axiom, but we argue that this axiom may not be aligned with the economic reality.
Public providers, or private providers, of public goods? A dynamic general equilibrium study

We study the difference between public production and public finance of public goods in a dynamic general equilibrium model. Under public production, public goods are produced by the government itself using public employees and goods purchased from the private sector. Under public finance, the same amount of public goods is produced by cost- minimizing private providers with the government financing their costs. When the model is solved numerically using fiscal data from the UK economy, we find that a switch from public production to public finance can have substantial aggregate and distributional implications. Also, public providers cannot beat private providers in terms of efficiency. The main message is that the following mix of reforms can be Pareto improving: (i) a transition to cost-minimizing private providers that allows the government to achieve efficiency savings (ii) a reduction in distorting income taxes made affordable by efficiency savings (iii) a mechanism (redistributive government transfers and, in particular, a reallocation of employees to the production of private goods) to reduce the rise in inequality caused by switching to private providers.
An experiential model of consumer engagement in social media

Purpose This study aims to propose an experiential model of consumer engagement focusing on Facebook brand pages. Building on the brand experience literature, the study synthesizes the experiential affordances of Facebook brand pages along perceptual, social, epistemic and embodied dimensions and tests their impact on consumer engagement. Design/methodology/approach The study operationalized key variables of the proposed model at the brand page level and assembled pertinent data, using systematic content analysis, on a sample of Facebook brand pages (n = 85). Poisson regression tested the proposed model. Findings The findings indicate that brands that facilitate greater number of experiential affordances on their Facebook brand pages generated higher levels of consumer engagement. For both brand post likes and brand post shares, the contributions of experiential affordances were significant and positive. Practical implications The findings offer actionable managerial insights for brands seeking to implement an experiential model of consumer engagement on their fan pages. Originality/value This study contributes to the literature by proposing and testing an experiential model of consumer engagement in the context of Facebook brand pages. To date, the experiential value of Facebook brand pages has rarely, if at all, been tested in an empirical study.

Infectious Bronchitis Virus E Protein Is Targeted to the Golgi Complex and Directs Release of Virus-Like Particles

ABSTRACT The coronavirus E protein is a poorly characterized small envelope protein present in low levels in virions. We are interested in the role of E in the intracellular targeting of infectious bronchitis virus (IBV) membrane proteins. We generated a cDNA clone of IBV E and antibodies to the E protein to study its cell biological properties in the absence of virus infection. We show that IBV E is an integral membrane protein when expressed in cells from cDNA. Epitope-specific antibodies revealed that the C terminus of IBV E is cytoplasmic and the N terminus is translocated. The short luminal N terminus of IBV E contains a consensus site for N-linked glycosylation, but the site is not used. When expressed using recombinant vaccinia virus, the IBV E protein is released from cells at low levels in sedimentable particles that have a density similar to that of coronavirus virions. The IBV M protein is incorporated into these particles when present. Indirect immunofluorescence microscopy showed that E is localized to the Golgi complex in cells transiently expressing IBV E. When coexpressed with IBV M, both from cDNA and in IBV infection, the two proteins are colocalized in Golgi membranes, near the coronavirus budding site. Thus, even though IBV E is present at low levels in virions, it is apparently expressed at high levels in infected cells near the site of virus assembly.
PRECISION MEDICINE: AN UPDATE ON GENOTYPE/BIOCHEMICAL PHENOTYPE RELATIONSHIPS IN PHEOCHROMOCYTOMA/PARAGANGLIOMA PATIENTS.

OBJECTIVE Pheochromocytomas and paragangliomas (PPGLs) are rare neuroendocrine tumors known to produce and secrete high levels of circulating catecholamines and their metabolites. The biochemical characteristics of these tumors can be used to divide them into three major phenotypes. The adrenergic, noradrenergic and dopaminergic phenotypes are defined by predominant elevations in epinephrine and metanephrine, norepinephrine and normetanephrine, and dopamine and 3-methoxytyramine, respectively. There are over 15 well-identified tumor-susceptibility genes responsible for approximately 40% of the cases. The objective of this review article is to outline specific genotype/biochemical phenotype relationships. METHODS Literature review. RESULTS None. CONCLUSION Biochemical phenotype of PPGL is determined by the underlying genetic mutation and the associated molecular pathway. Identification of genotype/biochemical relationships is valuable in prioritizing testing for specific genes, making treatment decisions and monitoring disease progression.

“PENGARUH SUPPLY CHAIN MANAGEMENT TERHADAP KINERJA OPERASIONAL OUTLET” (Studi Pada Counter Handphone yang terdaftar di PT. Multikom Indonesia Cabang Semarang)

The competitiveness of mobile phone stores and phone deposit outlets in Semarang are not attractive enough to the writer’s opinion. Owners should know and understand the need of their consumers. They choose Supply Chain Management as a strategy to enhance outlets’ operational and performance. The strategy is also aimed to increase the competitiveness of the business in the market. The research is aimed at analysing the impact of independent variables such as Information Sharing, Long Term Relationship, Cooperation and Process Integration to the dependent variables of the outlets’ performance. The population of the research consists of 171 outlets. The samples used in the research are 120 outlets owners in Semarang. Doubled linear analysis is used on this research. The writer used SPSS 16 for Windows as data processor tool. The result of the research explains that Information Sharing positively giving no significance toward outlets’ performance. In other hand, Long Term Relationship gives positive impact and significant to the outlets’ performance. The better Long Term Relationship between a mobile phone outlet and a distributor will improve the performance of the outlets. However, Cooperation positively giving no significance toward outlets’ performance. The better Integration Process between a mobile phone outlet and a distributor will help increasing the outlets’ performance.
The Influence Of Employee Empowerment, Ethical Climate, Organisational Support And Top Management Commitment On Employee Job Satisfaction. A Case Of Companies In The Gauteng Province Of South Africa

Manpower is a vital possession of any organization and the survival of any organization is dependent on the quality and empowerment of its employees, presence of good ethical climate, organizational support and commitment by top management to the organisation. An enabled manpower results in an efficient and effective organization. There is an urgent need for South Africa's companies to develop cultures that foster positive work environments and increase productivity. Achieving this is not an easy task and one of the ways to developing this culture is in the area of employee empowerment, ethical climate, organizational support and top management commitment which will ultimately lead to employee job satisfaction. Hence this paper is trying to look at the influence of employee empowerment, ethical climate, organisational support and top management commitment on employee job satisfaction, an area that seem to have been neglected by researchers considering companies in the Gauteng province of South Africa. In today’s work environment, employees are needed to make decisions, take initiative, take responsibility and find solutions to problems as well as being motivated and having the best interest of the company at heart. This study used a quantitative research methodology through using Smart PLS software to analyse the data. A sample of 200 registered companies in the Gauteng province was used to collect data from employees in both managerial and non-managerial positions. All the posited 4 hypotheses were supported by the data collected.
