End-Fire Vivaldi Antenna Array With Wide Fan-Beam for 5G Mobile Handsets

In this paper, we present a portable end-fire antenna array design for the fifth-generation (5G) mobile handsets that exploits a Vivaldi antenna and shows a wide fan-beam on the elevation plane. We make the proposed antenna array more efficient by printing on a 10-layer printed circuit board (PCB) lamination in a vertical direction of the ground plane edge. Using the proposed Vivaldi antenna array design, the radiation characteristics of $4\times 1$ linear arrays are fabricated. To validate the feasibility, we perform simulations and experiments. Simulation results show that the total efficiencies of the antenna array are higher than about 8.16 – 9.46 dBi for the scanning range between 0° to 60°. Measurement results display that the antenna has S11 reply less than −10 dB in the frequency area of 27.5 to 28.5 GHz and wide beamwidth (130.8° in elevation plan, 21.35° in azimuth plan). There is a high accord between the calculated and measured results and we consider that the results in this study can be well achieved by designers who design the wide beamwidth high-speed antennas of 5G mobile terminals.
Managing bushmeat hunting in Okapi Wildlife Reserve, Democratic Republic of Congo

Projected rates of agricultural clearing in the Ituri Forest of north-eastern Democratic Republic of Congo range from 0 to 0.1 per cent per year and suggest that deforestation for subsistence agriculture is not an immediate threat to the integrity of the Okapi Wildlife Reserve (OWR). If the human population continues to grow at over 3 per cent per annum, and bushmeat continues to be a major source of income for rural communities, subsistence-level exploitation of bushmeat may, however, not be sustainable. This paper proposes management approaches that address the demand for and supply of bushmeat, which are targeted at those political districts within the OWR where hunting is the greatest threat to populations of bushmeat species. These management approaches are designed to help conserve the Ituri's natural resources without compromising the health and income security of rural communities.
Variation-Aware Defect Characterization at Cell Level

Small Delay Faults (SDFs) are an indicator of reliability threats even if they do not affect the behavior of a system at nominal speed. Various defects may evolve over time into a complete system failure, and defects have to be distinguished from delays due to process variations which also change the circuit timing but are benign. Based on Monte-Carlo electrical simulation at cell level, in this work it is shown that a few measurements at different operating points of voltage and frequency are sufficient to identify a defect cell even if its behavior is completely within the specification range. The developed classifier is based on statistical learning and can be annotated to each element of a cell library to support manufacturing test, diagnosis and optimizing the burn-in process or yield.
Test Sequence-Optimized BIST for Automotive Applications

As the use of electronic components grows rapidly in the automotive industry, the number of complex safety-critical devices used in advanced driver assistance systems or autonomous cars is rising with high-end models containing more than 200 embedded microcontrollers. Achieving functionally safe automotive electronics requires test solutions that address challenges posed by high quality and long-term reliability requirements mandated, for example, by the ISO 26262 standard. The paper presents test pattern generation schemes for a scan-based logic BIST optimizing test coverage and test time during in-system test applications for automotive ICs. As a part of overall safety, they help in ensuring reliable operations of vehicle's electronics throughout their lifecycles. The proposed schemes can be deployed in different modes of in-system testing, including key-off, key-on, and periodic (incremental) online tests. Experimental results obtained for automotive designs and reported herein show improvements in test quality over conventional logic BIST schemes.
Green tea and health: An overview

Tea is the most widely consumed beverage in the world, except water. Recently, numerous researches have discovered the strong antioxidant potential mostly in green tea. This property is essentially due to catechins belonging to the polyphenolic flavonoids. These compounds are strong scavengers of free radicals and oxidants that could develop many ailments such as cancer, cardio-vascular disorders, inflammatory diseases, etc. Recent in vitro, animal and human studies have reported that green tea or its catechins may prevent cancer development, reduce cholesterol levels and hypertension, protect neurodegenerative diseases, improve dental health, etc. Although the antioxidant potential of green tea is evident, the results from epidemiological and clinical studies of the relationship between green tea and prevention of these diseases in humans are mixed. More controlled, well-designed clinical trials are needed to determine the effectiveness of green tea in human chemoprevention. The aim of this overview article is to revise the most recent medicinal studies of green tea, its chemical composition, its catechin pharmacokinetics and its side-effects.
Container Migration Mechanism for Load Balancing in Edge Network Under Power Internet of Things

As a novel computing technology closer to business ends, edge computing has become an effective solution for delay sensitive business of power Internet of Things (IoT). However, the uneven spatial and temporal distribution of business requests in edge network leads to a significant difference in business busyness between edge nodes. Due to the natural lightweight and portability, container migration has become a critical technology for load balancing, thereby optimizing the resource utilization of edge nodes. To this end, this paper proposes a container migration-based decision-making (CMDM) mechanism in power IoT. First, a load differentiation matrix model between edge nodes is constructed to determine the timing of container migration. Then, a container migration model of load balancing joint migration cost (LBJC) is established to minimize the impact of container migration while balancing the load of edge network. Finally, the migration priority of containers is determined from the perspective of resource correlation and business relevance, and by introducing a pseudo-random ratio rule and combining the local pheromone evaporation with global pheromone update at the same time, a migration algorithm based on modified Ant Colony System (MACS) is designed to utilize the LBJC model and thus guiding the choice of possible migration actions. The simulation results show that compared with genetic algorithm (GA) and Space Aware Best Fit Decreasing (SABFD) algorithm, the comprehensive performance of CMDM in load balancing joint migration cost is improved by 7.3% and 12.5% respectively.
Predict the Performance of Students and School on Educational Database (U-DISE)

In India, advancement in technology is imperative for the betterment of the education system. For improving the nature of education given to the understudies, the School must make a collective climate for Technological Changes. The Education System generates a large amount of data related to different indicators involved in the U-DISE+ and SDMIS database of the Education System. However, these indicators are considered as very important for quality Education. The goal of this paper is to anticipate the execution of School and understudies based on UDISE Plus information by utilizing different classification Algorithms.
SWR1-Independent Association of H2A.Z to the LINC Complex Promotes Meiotic Chromosome Motion

The H2A.Z histone variant is deposited into chromatin by the SWR1 complex affecting multiple aspects of meiosis. Here we describe a SWR1-independent localization of H2A.Z at meiotic telomeres and the centrosome. We demonstrate that H2A.Z colocalizes and interacts with Mps3, the SUN component of the LINC complex that spans the nuclear envelope and links meiotic telomeres to the cytoskeleton promoting meiotic chromosome movement. H2A.Z also interacts with the meiosis-specific Ndj1 protein that anchors telomeres to the nuclear periphery via Mps3. Telomeric localization of H2A.Z depends on Ndj1 and the N-terminal domain of Mps3. Although telomeric attachment to the nuclear envelope is maintained in the absence of H2A.Z, the distribution of Mps3 is altered. The velocity of chromosome movement during meiotic prophase I is reduced in the htz1Δ mutant lacking H2A.Z, but it is unaffected in swr1Δ cells. We reveal that H2A.Z is an additional LINC-associated factor that contributes to promote telomere-driven chromosome motion critical for error-free gametogenesis.
Observations on Ixodes eudyptidis Maskell (Acari: Ixodidae), Ornithodoros capensis Neumann (Acari: Argasidae), and other tick parasites of sea birds in New Zealand

Abstract The studies reported here represent a collection of experiments and observations on sea bird ticks over a number of years, undertaken on the rare occasions that material became available. Collection details from ticks in 70% ethanol were the source of basic seasonality data for 4 species. In addition, living Ixodes eudyptidis and Ornithodoros capensis collected from sea bird colonies were able to be fed in the laboratory using, respectively, mice and domestic chickens. Life cycle details were obtained from ticks kept at ambient temperature and in a moist atmosphere. Observations on birds in the field infested with I. eudyptidis showed that paralysis of the hosts was common, and in some instances was reversible once ticks were removed. Examples of paralysis caused by other ticks and the implications for bird conservation in New Zealand are discussed.
BEHAVIORAL SYNCHRONY IN IBEX GROUPS: EFFECTS OF AGE, SEX AND HABITAT

Summary Synchrony of activities is usually high in foraging groups, possibly to maintain group cohesion. Individuals with different levels of activity budgets, however, may have a hard time synchronizing their behavior to each other without incurring a cost. We predicted that the age and sex structure of a group would affect synchronization levels within a group because of differing individual activity budgets. Individuals in same-sex-age groups were hypothesized to show higher levels of activity synchrony than individuals in mixed sex-age groups. We investigated activity synchrony in adult male, adult female, subadult, and mixed sex-age groups of Alpine ibex — one of the most sexually dimorphic ruminant species. Activity budgets and movement rates were measured to calculate synchrony of activities between group members inJune and July 1999. Adult males were more synchronized with group peers than either females or subadults of both sexes. However, while adult males were synchronized in81% when inbachelor (adult male) groups, they were only synchronized in65% of the time when in mixed sex-age groups. Adult females were synchronized 61% of their time when in
Conservation Prospects for the Lion-Tailed Macaque (Macaca silenus) in the Forests of Sirsi-Honnavara, Western Ghats, India

Abstract: The lion-tailed macaque (Macaca silenus) is one of the most threatened of the primates of the Western Ghats. Confirmation of its large metapopulation in a relatively unprotected area (a reserve forest) of Karnataka has marked an important step for the future of this population. The number of lion -tailed macaques estimated was 638 in 31 groups with an average group size of 20.6, excluding lone males. A review of the literature confirms that this is one of the larger known populations in the wild. This reserve forest faces a number of threats because of anthropogenic activities such as habitat fragmentation, encroachment and developmental projects. In an attempt to save and restore the northernmost habitat of the lion-tailed macaque, we proposed that the forests where they live be declared a wildlife sanctuary or conservation reserve, using them as an umbrella species for conservation. In response to this, the forest department of the Government of Karnataka notified the proposed area, with only minor modifications to the boundary, as the ‘Aghanashini Lion-tailed Macaque Conservation Reserve’. We suggest some immediate management interventions to minimize further pressure on this highly threatened habitat.
Diabetic Retinopathy Image Classification Using Support Vector Machine

Diabetes is a leading cause of various serious diseases like kidney failure, cardiovascular problems and many more, blindness is one of them. As it progress it may affect the retina of the eye and leads to Diabetic retinopathy (DR). In this disease the retinal blood vessels start swelling and eventually retina gets damaged. This generally makes the patient total blind. The effective way of handle this disease is to detect and cure it at its earlier state. This needs regular screenings of the eye. There are several automatic screening techniques for the determination of the disease still there is a scope for the improvement in accuracy of prediction. One of the way to improve the accuracy is by considering important artifacts present in the retina; those play a vital role in disease prediction. In case of DR one important artifact is Exudates. Therefore, in this research two well-known predefined feature extraction techniques scale-invariant feature transform (SIFT) and speeded up robust features (SURF) have been used simultaneously on each retinal images to capture the Exudates regions. These Exudates of each image stored in a feature matrix and used by the support vector machine(SVM) classifier for prediction of DR. For a 100 set of test images the average sensitivity of the model is 94%.
Using Global Honeypot Networks to Detect Targeted ICS Attacks

Defending industrial control systems (ICS) in the cyber domain is both helped and hindered by bespoke systems integrating heterogeneous devices for unique purposes. Because of this fragmentation, observed attacks against ICS have been targeted and skilled, making them difficult to identify prior to initiation. Furthermore, organisations may be hesitant to share business-sensitive details of an intrusion that would otherwise assist the security community.In this work, we present the largest study of high-interaction ICS honeypots to date and demonstrate that a network of internet-connected honeypots can be used to identify and profile targeted ICS attacks. Our study relies on a network of 120 high-interaction honeypots in 22 countries that mimic programmable logic controllers and remote terminal units. We provide a detailed analysis of 80,000 interactions over 13 months, of which only nine made malicious use of an industrial protocol. Malicious interactions included denial of service and replay attacks that manipulated logic, leveraged protocol implementation gaps and exploited buffer overflows. While the yield was small, the impact was high, as these were skilled, targeted exploits previously unknown to the ICS community.By comparison with other ICS honeypot studies, we demonstrate that high-quality deception over long periods is necessary for such a honeypot network to be effective. As part of this argument, we discuss the accidental and intentional reasons why an internet-connected honeypot might be targeted. We also provide recommendations for effective, strategic use of such networks.
Delicate Fabric Handling Using a Soft Robotic Gripper With Embedded Microneedles

We propose a soft robotic gripper that can handle various types of fabrics with delicacy for applications in the field of garment manufacturing. The design was inspired by the adhesion mechanism of a parasitic fish called ‘lamprey’. The proposed gripper not only is able to pick up and hold a single sheet of fabric from a stack but also does not make any damages on it. In this work, we first modeled the holding force of the gripper and then experimentally evaluated its performance with different types of fabrics, in terms of the holding force and the response time. The experimental data showed a reasonable agreement with the predicted values by the model. The actuation time and the maximum holding force measured in the experiments were 0.32 seconds and 1.12 N, respectively. The gripper showed high success rates in picking up a single sheet of air permeable fabric, which was not possible by a commercial vacuum pad. It also showed durability in repeated motions of gripping test over 20,000 cycles. We believe the proposed gripper has a high potential in realizing smart manufacturing in garment industry.
First record of Halidrys siliquosa on the Portuguese coast: counter-intuitive range expansion?

The occurrence of the pod weed, Halidrys siliquosa , is recorded for the first time on the Portuguese coast. Several specimens of this brown algae were observed attached to the rocky surface in tide pools at 41o44′10″N 8o52′34″W, extending southward its previously known geographical distribution. The observed shift is inconsistent with general predictions of species migrations under warming climate conditions, which anticipate poleward shifts rather than southern expansions. Although more data will be required to undoubtedly uncover its cause, the recently observed range expansion raises important questions about the generalization of the previously stated biogeographic rules.
Predicting invasiveness of Australian acacias on the basis of their native climatic affinities, life history traits and human use

Aim Many Australian Acacia species have been widely planted around the world. Some taxa are among the most aggressive of invasive alien plants and cause severe ecosystem degradation. We aimed to predict invasiveness of taxa in a large set of Australian Acacia species on the basis of easy‐to‐assess predictors.
n-3 PUFA and inflammation: from membrane to nucleus and from bench to bedside

Inflammation is a normal part of the immune response and should be self-limiting. Excessive or unresolved inflammation is linked to tissue damage, pathology and ill health. Prostaglandins and leukotrienes produced from the n-6 fatty acid arachidonic acid are involved in inflammation. Fatty acids may also influence inflammatory processes through mechanisms not necessarily involving lipid mediators. The n-3 fatty acids EPA and DHA possess a range of anti-inflammatory actions. Increased content of EPA and DHA in the membranes of cells involved in inflammation has effects on the physical nature of the membranes and on the formation of signalling platforms called lipid rafts. EPA and DHA interfere with arachidonic acid metabolism which yields prostaglandins and leukotrienes involved in inflammation. EPA gives rise to weak (e.g. less inflammatory) analogues and both EPA and DHA are substrates for the synthesis of specialised pro-resolving mediators. Through their effects on early signalling events in membranes and on the profile of lipid mediators produced, EPA and DHA alter both intracellular and intercellular signals. Within cells, this leads to altered patterns of gene expression and of protein production. The net result is decreased production of inflammatory cytokines, chemokines, adhesion molecules, proteases and enzymes. The anti-inflammatory and inflammation-resolving effects of EPA and DHA are relevant to both prevention and treatment of human diseases that have an inflammatory component. This has been widely studied in rheumatoid arthritis where there is good evidence that high doses of EPA + DHA reduce pain and other symptoms.
Quantitative Analysis of Ku70 and Ku80 mRNA Gene Expression in Melanoma Brain Metastases. Correlation with Immunohistochemistry and In Situ Hybridization.

BACKGROUND Altered expression and prognostic significance of DNA double-strand repair genes Ku70 and Ku80 has been shown by our research group for malignant melanomas. High genomic instability known for melanoma brain metastases stimulated us to analyze Ku70 and Ku80 expression in melanoma brain metastases. MATERIALS AND METHODS Quantitative evaluation of mRNA Ku70 and Ku80 expression was performed in 13 melanoma brain metastases. Immunohistochemistry and in situ hybridization for Ku70 and Ku80 were applied to 34 metastatic tumours. RESULTS Quantitative analysis of Ku70 mRNA expression demonstrated values between 0.01 and 0.33. Ku80 mRNA expression ranged between 0.001 and 0.54. Immunohistochemistry demonstrated Ku70 and Ku80 expression in 34 and in 25 metastatic tumours, respectively. In situ hybridization detected Ku70 expression in 19/34 and Ku80 expression in 13/34 metastatic tumours. Correlation between Ku70 and Ku80 expression in melanoma brain metastases was lost. CONCLUSION Ku70 and especially Ku80 expression is altered in melanoma brain metastases and corresponds with the high genomic instability of these lesions.
Soy/whey protein isolates: Interfacial properties and effects on the stability of oil-in-water emulsions.

BACKGROUND The adsorption of proteins at oil/water interfaces can reduce interfacial tension and increase emulsion stability. However, emulsions stabilized by soy protein isolate (SPI) are not sufficiently stable. Using SPI as a control, a theoretical basis for the adsorption behavior of mixed SPI and whey protein isolate (WPI) at the oil/water interface was established and the effects of the protein ratio and content on the emulsion stability were studied. RESULTS Compared to SPI solution, SPI-WPI mixed solutions were found to reduce the size distribution of emulsion droplets and significantly improve the emulsion stability. Among the studied protein contents and ratios, the protein content of 0.2 g kg-1 and SPI/WPI mass ratio of 1:9 offered the lowest creaming stability index (15%), the smallest droplet size (278 nm), and the largest absolute value ζ-potential (35 mv), i.e. the emulsion stability was excellent. The largest dilatational modulus (10.08 mN m-1 ), dilatational elasticity (10.01 mN m-1 ), and dilatational viscosity (1.18 mN m-1 ), were observed with a protein content of 0.15 g kg-1 (SPI/WPI ratio of 1:9), along with a high interfacial protein adsorption capacity (47.33%). SPI-WPI complexes form a thick adsorption layer around oil droplets, resulting in an increase of the expansion modulus of the interfacial layer. CONCLUSION SPI-WPI complexes can form a thick adsorption layer around oil droplets, resulting in increased expansion modulus of the interfacial layer, which improves emulsion stability.

Lake restoration by biomanipulation- a personal view

Restoration of over-fertilized, algae-laden lakes and reservoirs has generally been based on removal or reduction of phosphorus inputs and concentrations. However, this approach frequently is not feasible. An alternative is biomanipulation, in which the biota of the water body, particularly the fish population, is manipulated so as to reduce predation on small herbivorous zooplankters. This results in increases in body size of the zooplankters with consequent great increases in grazing rates on the algae. The process, though controversial, has worked in many lakes and offers promise to many more.Key words: biomanipulation, trophic cascade, lake restoration.
