Determination of Complex Permittivity of Low-Loss Samples From Position-Invariant Transmission and Shorted-Reflection Measurements

In this paper, we devise a position-invariant method for unique and accurate complex permittivity (<inline-formula> <tex-math notation="LaTeX">$\varepsilon _{r}$ </tex-math></inline-formula>) determination of low-loss samples from transmission and shorted-reflection scattering (S-) parameter measurements while mitigating the effect around Fabry–Perot frequencies. For this goal, we derived a metric function in terms of propagation factor <inline-formula> <tex-math notation="LaTeX">$T$ </tex-math></inline-formula> only and utilized a branch-index-independent expression for unique <inline-formula> <tex-math notation="LaTeX">$\varepsilon _{r}$ </tex-math></inline-formula> by eliminating multiple solutions problem. We measured S-parameters of two low-loss samples with substantial thickness, which both introduced a Fabry–Perot effect in the frequency range, and the measurements were conducted to validate our method and compare its accuracy with the accuracy of similar methods in the literature. We also performed an uncertainty analysis to evaluate and improve the accuracy of our method.
Analysis and Design of a Broadband Multifeed Tightly Coupled Patch Array Antenna

In this letter, a multifeed tightly coupled patch array antenna capable of broadband operation is analyzed and designed. First, an antenna array composed of infinite elements with each element excited by a feed is proposed. To produce specific polarized radiation efficiently, a new patch element is proposed, and its characteristics are studied based on a 2-port network model. Full-wave simulation results show that the infinite antenna array exhibits both a high efficiency and desirable radiation pattern in a wide frequency band (10 dB bandwidth) from 1.91 to 5.35 GHz (94.8%). Second, to validate its outstanding performance, a realistic finite 4 × 4 antenna prototype is designed, fabricated, and measured in our laboratory. The experimental results agree well with simulated ones, where the frequency bandwidth (VSWR < 2) is from 2.5 to 3.8 GHz (41.3%). The inherent compact size, light weight, broad bandwidth, and good radiation characteristics make this array antenna a promising candidate for future communication and advanced sensing systems.
Plants of the Melaleuca Genus as Antimicrobial Agents: From Farm to Pharmacy

Plants belonging to Melaleuca genus (Myrtaceae family) are native to Oceania, where they have been used for ages by Aborigine people in Australian traditional medicine, mainly because of their broad‐spectrum antimicrobial activity. Although, M. linariifolia, M. dissitiflora, and other species of Melaleuca can also be used, the tea tree oil, an essential oil obtained from M. alternifolia shows the longest history of medicinal uses. Tea tree oil contains for the 80–90% several monoterpenes (terpinen‐4‐ol, α‐terpinene, 1,8‐cineol, p‐cymene, α‐terpineol, α‐pinene, terpinolene, limonene, and sabinene). Sesquiterpenes and aromatic compounds further compose this oil. The essential oil of Melaleuca spp. has been reported to possess effective antibacterial and antifungal properties in vitro. In particular, data show that 1,8‐cineol, terpinen‐4‐ol and methyl eugenol play the key role in mediating this oil's antimicrobial activity. Copyright © 2017 John Wiley & Sons, Ltd.
Full-Duplex Cognitive Radio With Asynchronous Energy-Efficient Sensing

Using a novel embedded Markov chain, we model and analyze a cognitive radio performing full-duplex spectrum sensing which is being carried out imperfectly—i.e., with errors—and asynchronously with primary traffic, from the perspective of energy efficiency. The effect of sensing frequency, which is varied by inserting sleeping periods between sensing processes is investigated, with focus on: 1) the energy efficiency of the device measured in terms of the number of successful transmissions under a limited battery budget; 2) the average throughput; and 3) the collision with the primary’s traffic. We show analytically that, given false-alarm and mis-detection probabilities, the device’s operation in lower-than-maximum sensing frequency may be more energy-efficient than that in maximum-frequency sensing case, while the radio is neither suffering throughput degradation nor disturbing the primary traffic seriously. We validate the deployment of such full-duplex cognitive radio (FDCR) along with the proposed sensing scheme for low-power short-range applications like wireless machine-to-machine communications and sensor networks, where the share of sensing power is comparable to that of transmission power. The merits of the proposed FDCR scheme are demonstrated through comparisons with a half-duplex cognitive radio scheme under different operating conditions and full-duplex self-interference cancellation factors.
Predicting Occupational Strain and Job Satisfaction: The Role of Stress, Coping, Personality, and Affectivity Variables

Abstract Four studies employed path analysis to examine how measures of occupational stressors, coping resources, and negative affectivity (NA) and positive affectivity (PA) interact to predict occupational strain. The Occupational Stress Inventory (Osipow & Spokane, 1987) was used to measure stress, strain, and coping. The Positive and Negative Affectivity Schedule (Watson, Clark, & Tellegen, 1988) was used for the affectivity variables. The hypothesized model showed NA and PA as background dispositional variables that influenced relations among stress, strain, and coping while still allowing stress and coping to have a direct influence on strain. Goodness of fit indices were acceptable with the model predicting 15% of the variance in stress, 24% of coping, and 70% of strain. Study 2 replicated these findings. Study 3 added a positive outcome variable, job satisfaction (JSI: Brayfield & Rothe, 1951), to the model. The expanded model again fit the data well. A fourth study added a global measure of personality (NEO–FFI: Costa & McCrae, 1991) to the model tested in Study 3. Results indicated that personality measures did not add anything to the prediction of job satisfaction and strain in a model that already included measures of stressors, coping resources, NA, and PA. The series of four studies yielded a reliable structural model that highlights the influence of organizational and dispositional variables on occupational strain and job satisfaction.
SoI Monolithic Active Pixel Sensors for Radiation Detection Applications: A Review

Silicon-on-insulator (SoI) monolithic active pixel sensors have been developing fast in recent years. An SoI sensors use a thin low-resistivity upper Si layer for circuit implementation, and a high-resistivity bottom wafer as a sensor, sandwiching a buried oxide layer. These devices can be made very thin, fully depleted, avoiding bump bonding. In addition, they have fine pitch and low capacitance. An SoI pixel is a very attractive technology due to its inherent advantages. An SoI pixel process for monolithic radiation detectors is developed mainly based on Lapis Semiconductor Co. Ltd. 0.2-μm SoI FD-CMOS technology. The multilateral developments for both fundamental properties and dedicated application are progressing simultaneously. There have been many research projects on high-energy physics, space experiments, synchrotron radiation and industrial scan, and so on. Difficulties are unavoidable in the R&D process and many of them are solved by introducing new techniques, process/structure modifications, such as buried p-well, double-SoI, and 3-D vertical integration. This paper provides a review of the SoI sensor development: the theory; features; key issues; process; research; and applications.
Plasmodium knowlesi: a superb in vivo nonhuman primate model of antigenic variation in malaria

SUMMARY Antigenic variation in malaria was discovered in Plasmodium knowlesi studies involving longitudinal infections of rhesus macaques (M. mulatta). The variant proteins, known as the P. knowlesi Schizont Infected Cell Agglutination (SICA) antigens and the P. falciparum Erythrocyte Membrane Protein 1 (PfEMP1) antigens, expressed by the SICAvar and var multigene families, respectively, have been studied for over 30 years. Expression of the SICA antigens in P. knowlesi requires a splenic component, and specific antibodies are necessary for variant antigen switch events in vivo. Outstanding questions revolve around the role of the spleen and the mechanisms by which the expression of these variant antigen families are regulated. Importantly, the longitudinal dynamics and molecular mechanisms that govern variant antigen expression can be studied with P. knowlesi infection of its mammalian and vector hosts. Synchronous infections can be initiated with established clones and studied at multi-omic levels, with the benefit of computational tools from systems biology that permit the integration of datasets and the design of explanatory, predictive mathematical models. Here we provide an historical account of this topic, while highlighting the potential for maximizing the use of P. knowlesi – macaque model systems and summarizing exciting new progress in this area of research.
Screening for therapeutic targets of vorinostat by SILAC‐based proteomic analysis in human breast cancer cells

Histone deacetylases (HDACs) play critical roles in silencing tumor suppressor genes. HDAC inhibitors reactivate tumor suppressor genes and inhibit tumor cell growth in vitro and in vivo, and several HDAC inhibitors are currently being evaluated in clinical trials for cancer therapy. A comprehensive analysis of proteins regulated by HDAC inhibitors would enhance our ability to define and characterize their essential therapeutic targets. Here, we employed stable isotope labeling with amino acids in cell culture‐based quantitative proteomics to identify acetylated proteins in human breast cancer cells. Treatment with the clinically relevant HDAC inhibitor, suberoylanilide hydroxamic acid (vorinostat), induces lysine acetylation of 61 proteins in MDA‐MB‐231 human breast cancer cells. Suberoylanilide hydroxamic acid not only induces lysine acetylation in chromatin‐associated proteins, but also acetylates previously unrecognized nonhistone proteins, including transcriptional factors and regulators, chaperones, cell structure proteins, and glycolytic enzymes in a time‐dependent manner. Knowledge of the full repertoire of acetylated proteins will provide a foundation for further defining the functions of HDACs in cancer cells.
Co- and Counterphasing Tolerances for Dual-Pump Parametric $\lambda$ -Conversion of D(Q)PSK Signals

Recently, we have shown that a pump-phase modulation in single-pump parametric wavelength converters introduces severe signal degradations on differential (quadrature) phase-shift keying signals. In this letter, we extend our investigations to dual-pump parametric wavelength converters. It will be shown that even small deviations from ideal co- and counterphasing can lead to similar optical signal-to-noise ratio penalties as in the single-pump case. This nonideal behaviour can occur due to imperfections in the pump-phase modulation scheme as well as through walk-off between the pumps that is unavoidable for full tunable operation.
Taxonomic, phylogenetic and ecological diversity of Niphargus (Amphipoda: Crustacea) in the Hölloch cave system (Switzerland)

Groundwater belongs to the spatially most extensive, but least explored freshwater systems. On a global scale, the species richness of several subterranean invertebrate taxa parallels species richness found in surface waters, while on a local scale species richness hardly exceeds 20 species. This results in a high contribution of groundwater ecosystems to regional β- and γ-diversity, and to a smaller degree to α-diversity, and deserves focused attention. In general, more species are to be found in large cave systems. The second largest cave system in Europe is Hölloch in Switzerland. In this paper we revised the taxonomic, phylogenetic and ecological diversity of the amphipod community in the Hölloch cave system. While previous records listed five geographically widespread species of the genus Niphargus for this cave system, we could not confirm the presence of any of those species, but rather found three highly distinct species new to science. In this paper we describe Niphargus styx sp. nov., Niphargus murimali sp. nov., and Niphargus muotae sp. nov., and suggest that previous records from that cave were probably misidentifications. Although amphipod species richness in this cave system seems to be lower than previously thought in terms of absolute numbers, the cave retained its regional and international importance in terms of nature conservation for multiple reasons. First, all newly described species are probably endemic to this cave system. Second, they are phylogenetically distantly related and exhibit moderate to high phylogenetic diversity. Third, the species, as inferred from their functional morphology, are also ecologically highly divergent. Based on geographic distribution of their nearest relatives, we hypothesize that the cave system was most likely independently colonized from North, West and South and that the pre-adapted ancestors occupied different ecological niches within the system. http://zoobank.org/urn:lsid:zoobank.org:pub:A19309E5-C06B-4844-A4D8-7571F05F25C9
INFORMATION TECHNOLOGY IN BANKING SECTOR

Electronic banking is generally an extension of traditional banking, using the internet as an electric delivery channel for banking products and services. The banking today is redefined and re-engineered with the use of IT and it is sure that the future of banking will offer more sophisticated services to customers with the continuous product and process innovations. Thus there is a paradigm shift from seller‟s market to buyer‟s market. So banks also change their approach from “Conventional Banking to Convenience Banking” and “Mass banking to Class Banking”. The study examines various relevant issues relating to role of IT in banking and recommends to ensure privacy and confidentiality of data‟s, implement IT and other Cyber laws properly. This will ensure the developmental role of IT in the banking industry.
Hepatitis B Virus Genotype Change in Children Is Closely Related to HBeAg/Anti-HBe Seroconversion

Background and Objectives: Genotype changes have been observed during long-term follow-up in adults with chronic hepatitis B virus (HBV) infection. The aim of this study was to assess the frequency and distribution of HBV genotype shifts in treated and untreated European children during the different phases of chronic hepatitis B. Methods: The initial population consisted of 85 HBeAg-positive children who were sequentially investigated for HBV genotypes for a mean period of 7.1 years. During the survey, 65 patients seroconverted to anti-HBe and 24 received antiviral treatment. Genotyping was done by restriction fragment length polymorphism. Results: Genotypes at enrollment were distributed as follows: D (n = 67), A (n = 11), B (n = 4), and C and mixed (n = 3). A genotype change was observed in 16 (19%) participants at last visit, of whom 1 of 20 (5%) remained persistently HBeAg positive and 15 of 65 (23%) children had seroconverted to anti-HBe (P < 0.001). The genotype shift was D to A or B in 9 individuals, A to D in 5, and A to B in 1. Genotype changes were more frequent in untreated than in treated subjects; however, the difference was not statistically significant. Conclusions: The results of this study suggest that genotype change is a relatively frequent event in children with chronic hepatitis B after anti-HBe seroconversion and independent of treatment. The reasons why only some patients will experience this event remain to be clarified.
Minimum specific energy and transcritical flow in unsteady open-channel flow

AbstractThe study and computation of free surface flows is of paramount importance in hydraulic and irrigation engineering. These flows are computed using mass and momentum conservation equations, their solutions exhibiting special features depending on whether the local Froude number (F) is below or above unity, thereby resulting in wave propagation in the upstream and downstream directions or only in the downstream direction, respectively. This dynamic condition is referred to in the literature as critical flow and is fundamental to the study of unsteady flows. Critical flow is also defined as the state at which the specific energy and momentum reach a minimum, based on steady-state computations, and it is further asserted that the backwater equation gives infinite free surface slopes at control sections. So far, these statements were not demonstrated within the context of an unsteady-flow analysis, to be conducted in this paper for the first time. It is demonstrated that the effects of unsteadiness bre.
Designing an online lecture in the discipline of soil science

Technological developments have not only been introduced to support traditional face to face education, but also to facilitate the spread of distance education programs and online learning. This paper contributes to the development of online lectures based on the foundations provided by learning theories (behaviourism, cognitivism, constructivism and connectivism). Using this approach, the author has developed an online lecture in the discipline of soil science on the topic ‘crop residue management and phosphorus cycling’. Different aspects of designing an online lecture in terms of the content of lecture and its organisation, learner preparation, a couple of activities to engage students, and strategies to promote interaction have been discussed in detail. This lecture is designed for use in future and the feedback received by authors would be effectively utilised to improve upon this practice.

Complementary switching in metal oxides: Toward diode-less crossbar RRAMs

A major challenge in achieving high density crossbar arrays based on resistive-switching memory (RRAM) is the identification of a select device (e.g. diode) with suitable supply current and on-off swing. Recently, the complementary resistance switch (CRS) concept based on a 2-RRAM stack was proposed to solve the sneak-path problem in crossbar arrays [1]. This work demonstrates complementary switching (CS) in single-stack nonpolar-RRAM devices. After describing CS characteristics by simulations, we show the operation under DC/pulsed regime and discuss methods to improve the resistive window. Finally, a unified model for unipolar, bipolar and complementary switching in oxide-RRAM is proposed.
Back radiation minimization of ultra wideband Vivaldi antenna for radar application

This paper deals with the minimization of the back radiation of the Vivaldi antenna for the radar application (e.g. portable through-wall radars). The high back radiation can give rise to the reflection from the radar operator or from the area behind the radar. These reflections can influence negatively the captured useful signal. Consequently, the measured view of the guarded area can be distorted or the undesired reflections can lead to a false alarm. In the paper, several types of shielding for the back radiation minimization are presented: an antenna with planar back-plane, a boxed antenna, a skewed and boxed antenna and a skewed and boxed antenna with planar frontplane. The reflections, radiated impulses and their distortion are discussed.
Hamel bases and well–ordering the continuum

In ZF, the existence of a Hamel basis does not yield a well–ordering of R. Throughout this paper, by a Hamel basis we always mean a basis for R, construed as a vector space over Q. We denote by E the Vitali equivalence relation, xEy iff x− y ∈ Q for x, y ∈ R. We also write [x]E = {y : yEx} for the E–equivalence class of x. A transversal for the set of all E–equivalence classes picks exactly one member from each [x]E . The range of any such transversal is also called a Vitali set. A set Λ ⊂ R is a Luzin set iff Λ is uncountable but Λ ∩M is at most countable for every meager set M ⊂ R. A set S ⊂ R is a Sierpiński set iff S is uncountable but S ∩ N is at most countable for every null set N ⊂ R (“null” in the sense of Lebesgue measure). A set B ⊂ R is a Bernstein set iff B ∩P 6= ∅ 6 = P \B for every perfect set P ⊂ R. It has been well–known for more than a century that the existence of a well– ordering of the reals implies the existence of all these “pathological” sets of reals: 1The first author gratefully acknowledges support from the Marianne und Dr. Horst KiesowStiftung, Frankfurt a.M. 2The second author was partially supported by the SFB 878 “Groups, geometry, and actions” from the DFG (Deutsche Forschungsgemeinschaft).

Peptide-Mediated Liposome Fusion: The Effect of Anchor Positioning

A minimal model system for membrane fusion, comprising two complementary peptides dubbed “E” and “K” joined to a cholesterol anchor via a polyethyleneglycol spacer, has previously been developed in our group. This system promotes the fusion of large unilamellar vesicles and facilitates liposome-cell fusion both in vitro and in vivo. Whilst several aspects of the system have previously been investigated to provide an insight as to how fusion is facilitated, anchor positioning has not yet been considered. In this study, the effects of placing the anchor at either the N-terminus or in the center of the peptide are investigated using a combination of circular dichroism spectroscopy, dynamic light scattering, and fluorescence assays. It was discovered that anchoring the “K” peptide in the center of the sequence had no effect on its structure, its ability to interact with membranes, or its ability to promote fusion, whereas anchoring the ‘E’ peptide in the middle of the sequence dramatically decreases fusion efficiency. We postulate that anchoring the ‘E’ peptide in the middle of the sequence disrupts its ability to form homodimers with peptides on the same membrane, leading to aggregation and content leakage.
