Review on the use of piezoelectric materials for active vibration, noise, and flow control

Considering the number of applications, and the quantity of research conducted over the past few decades, it would not be an overstatement to label the piezoelectric materials as the cream of the crop of the smart materials. Among the various smart materials, the piezoelectric materials have emerged as the most researched material for practical applications. They owe it to a few key factors like low cost, large frequency bandwidth of operation, availability in many forms, and the simplicity offered in handling and implementation. For piezoelectric materials, from an application standpoint, the area of active control of vibration, noise, and flow, stands, alongside energy harvesting, as the most researched field. Over the past three decades, several authors have used piezoelectric materials as sensors and actuators, to (i) actively control structural vibrations, noise and aeroelastic flutter, (ii) actively reduce buffeting, and (iii) regulate the separation of flows. These studies are spread over several engineering disciplines—starting from large space structures, to civil structures, to helicopters and airplanes, to computer hard disk drives. This review is an attempt to concise the progress made in all these fields by exclusively highlighting the application of the piezoelectric material. The research carried out in the past five years, in the areas of modeling, and optimal positioning of piezoelectric actuators/sensors, for active vibration control (AVC), are covered. Along with this, investigations into different control algorithms, for the piezoelectric based AVC, are also reviewed. Studies reporting the use of piezoelectric modal filtering and self sensing actuators, for AVC, are also surveyed. Additionally, research on semi-AVC techniques like the synchronized switched damping (on elements like resistor, inductor, voltage source, negative capacitor) has also been covered.

To assess the nutritional status among elderly and factors influencing it, in an urban area, Bengaluru - a cross sectional study

Background: Elderly population is on raise globally and in India. Malnutrition in old age, significantly increases the susceptibility to infection, compromises the outcomes of other underlying conditions and diseases and hence increases the risk of morbidity and mortality. The malnourished elderly are more likely to require more hospitalizations, cause burden to caregivers and possess a huge economic cost to society. This facilitates the need for early detection of malnourishment among elderly by assessing the nutritional status as a part of geriatric evaluation therefore appropriate measures can be taken to overcome the malnourishment and associated complications. Hence this study attempts to assess the nutritional status and factors influencing it among elderly, in an urban area, Bengaluru. Methods: A cross-sectional study was conducted among 300 elderly population aged ≥60 years in an urban area, Bengaluru during April to August 2016. Results: Among the study participants majority 182 (60.66%) were females and 64(21.33%) were malnourished. Nutritional status was found to worsen significantly with advancing age (χ²=42.12, P value <0.0001), Illiteracy (χ²=16.19, P value 0.0003), dependent financial status ( χ²= 16.45, P value 0.0003) and living arrangements without spouse and/or children ( χ²= 14.17, P value 0.0278). Good awareness but low utilization levels of the old age social security scheme was noted among the study population. Conclusions: Old age can only be protected, promoted and extended by adding quality to life. Geriatric nutritional status assessment helps to detect the malnourished and those at risk of malnutrition at an early stage, following which an early corrective interventions can improve their quality of life.
Age of the Berlin moraine complex, New Hampshire, USA, and implications for ice sheet dynamics and climate during Termination 1

Abstract At its late Pleistocene maximum, the Laurentide Ice Sheet was the largest ice mass on Earth and a key player in the modulation of global climate and sea level. At the same time, this temperate ice sheet was itself sensitive to climate, and high-magnitude fluctuations in ice extent, reconstructed from relict glacial deposits, reflect past changes in atmospheric temperature. Here, we present a cosmogenic 10Be surface-exposure chronology for the Berlin moraines in the White Mountains of northern New Hampshire, USA, which supports the model that deglaciation of New England was interrupted by a pronounced advance of ice during the Bølling-Allerød. Together with recalculated 10Be ages from the southern New England coast, the expanded White Mountains moraine chronology also brackets the timing of ice sheet retreat in this sector of the Laurentide. In conjunction with existing chronological data, the moraine ages presented here suggest that deglaciation was widespread during Heinrich Stadial 1 event (~18–14.7 ka) despite apparently cold marine conditions in the adjacent North Atlantic. As part of the White Mountains moraine system, the Berlin chronology also places a new terrestrial constraint on the former glacial configuration during the marine incursion of the St. Lawrence River valley north of the White Mountains.
Consumer Palatability of Beef Muscles From Australian and US Production Systems With or Without Enhancement

The objective was to assess the consumer (n = 360) palatability and satisfaction of enhanced (7%) and nonenhanced Australian grain-fed, Australian grass-fed, and US grain-fed beef from 2 beef muscles. Strip loin (longissimus lumborum [LL]) and top sirloin butt (gluteus medius [GM]) subprimals were collected from 12 Australian grass-fed, 12 Australian grain-fed, and 12 US grain-fed (USDA Choice) carcasses. In addition, tenderloin (psoas major) and eye of round (semitendinosus) subprimals were collected from the same US carcasses to serve as anchors for high and low palatability. All subprimals were aged until 29 to 32 d postmortem. All fabrication and enhancement occurred in Lubbock, Texas. Data were analyzed initially as a randomized complete design and subsequently as a split-split plot design, with the main effects of country of origin/diet (Australian grain-fed, Australian grass-fed, and US grain-fed), muscle (LL and GM), and enhancement (0% or 7%) and all potential interactions as fixed effects. Enhancement significantly improved palatability in both LL and GM steaks as evidenced by greater (P 0.05) to nonenhanced grain-fed beef. This response to enhancement was observed in consumer scores for both LL and GM samples. Consumers could not detect differences (P > 0.05) in tenderness, juiciness, flavor, overall liking, or satisfaction between grain-fed beef from Australia and the US.
Prevalence of Antimicrobial Utilization in a Tertiary Care Teaching Hospital

Background: Antibiotic resistance is said to be direct consequence of antibiotic use. Inappropriate prescribing and use practices are putting patients at unnecessary risk for acquisition and spread of resistant and difficult-to-treat pathogens. Methods: A total of 600 prescriptions from various O.P.Ds and 400 case record sheets of the in-patients, 100 each from the department of Medicine, Pediatrics, Obstetrics and Gynecology and Surgery were collected. The data was analyzed as per WHO outpatient prescribing indicators and appropriate prescribing indicators for inpatient antibiotic use. Results: OPD based prescriptions contained 1574 medicines with an average of 2.63 medicines per prescription. Total of 218 antibiotics were prescribed, 3 (1.4%) antibiotics were prescribed as injections. On the whole β-lactams (38.5%) were the most commonly prescribed group. Inpatients case records contained 2958 medicines. Total 606 antibiotics were prescribed for 297 (74%) inpatients that received an average of 2.04 antibiotics. β-lactam was the most commonly prescribed group of antibiotics in the inpatient department. Conclusion: Preparation and implementation of Standard treatment guidelines, antibiotic prescribing policy, prescribing from essential medicine list can make prescribing more rational, safe and help reducing cost of therapy.
Genome-Centered Metagenomics Analysis Reveals the Microbial Interactions of a Syntrophic Consortium during Methane Generation in a Decentralized Wastewater Treatment System

The application of anaerobic digestors to decentralized wastewater treatment systems (DWTS) has gained momentum worldwide due to their ease of operation, high efficiency, and ability to recycle wastewater. However, the microbial mechanisms responsible for the high efficiency and ability of DWTS to recycle wastewater are still unclear. In this study, the microbial community structure and function of two different anaerobic bioreactors (a primary sludge digestor, PSD, and anaerobic membrane bioreactor, AnMBR) of a DWTS located in Germany was investigated using 16S rRNA gene amplicon and metagenomic sequencing, respectively. The results showed that the microbial community structure was remarkably different in PSD and AnMBR. Methanobacteriaceae and Syntrophaceae were identified as the families that significantly differed in abundance between these two bioreactors. We also used genome-centered metagenomics to predict the microbial interactions and methane-generating pathway, which yielded 21 near-complete assembled genomes (MAGs) (average completeness of 93.0% and contamination of 2.9%). These MAGs together represented the majority of the microbial community. MAGs affiliated with methanogenic archaea, including Methanobacterium sp. , Methanomicrobiales archaea, Methanomassiliicoccales archaea, and Methanosaeta concilii, were recruited, along with other syntrophic bacterial MAGs associated with anaerobic digestion. Key genes encoding enzymes involved in specific carbohydrate-active and methanogenic pathways in MAGs were identified to illustrate the microbial functions and interactions that occur during anaerobic digestion in the wastewater treatment. From the MAG information, it was predicted that bacteria affiliated with Bacteroidetes, Prolixibacteraceae, and Synergistaceae were the key bacteria involved in anaerobic digestion. In the methane production step, Methanobacterium sp. performed hydrogenotrophic methanogenesis, which reduced carbon dioxide to methane with hydrogen as the primary electron donor. Taken together, our findings provide a clear understanding of the methane-generating pathways and highlight the syntrophic interactions that occur during anaerobic digestion in DWTS.
Improvement of growth performance, digestive enzymes and body composition of Persian sturgeon (
 Acipenser persicus
 ) following feeding on probiotics:
 Bacillus licheniformis
 ,
 Bacillus subtilis
 and
 Saccharomyces cerevisiae

The individual and combinational effects of probiotics on Persian sturgeon (Acipenser persicus) were evaluated through assessing the growth performance, proximate body composition, digestive enzymes and intestinal morphology. On the basis of feeding with experimental diets, the fish were assigned into four groups denoted as follows: control (basal diet), D‐Pro (basal diet + Bacillus subtilis and Bacillus licheniformis), D‐Pro/Yeast (basal diet + B. subtilis and B. licheniformis + Saccharomyces cerevisiae), Yeast (basal diet + S. cerevisiae). Maximum mean weight and length were measured for the fish fed with D‐pro regime. weight gain (WG), body weight gain (BWI%), feed efficiency (FE%), protein efficiency rate (PER), lipid efficiency rate (LER), and condition factor (CF) demonstrated the highest values for the fish fed with the diets containing D‐Pro and/or D‐Pro/yeast. LER and food conversion ratio (FCR) showed the highest performance for the fish received the D‐Pro diet. The diets containing D‐Pro exhibited higher performance in enhancing the activity of protease and lipase than the one supplemented only with the yeast, whereas the regimes treated with the yeast exhibited higher amylase activity. The fish received D‐Pro exhibited the highest protein and fat contents, yet did the lowest contents of moisture and total ash. Taken together, the findings revealed that the dietary administration of the D‐Pro and D‐Pro/Yeast could improve the growth performance of A. persicus.
Impact of different cadmium concentrations on two Pisum sativum L. genotypes

This study was conducted to evaluate the effect of different concentrations of cadmium (Cd) (0, 100, 200, and 400 μM Cd) on two genotypes (AG-10 and AP-3) of Pisum sativum. Cd stress reduced the length, fresh weight, and dry weight of roots and shoots in both genotypes. Chlorophyll ‘a’ and ‘b’ and carotenoid content was also decreased and greater decreases were observed for higher concentrations of Cd. As Cd stress increased, levels of proline, glycine betaine, and soluble proteins were increased and sugar content was decreased. The application of Cd also caused an increase in hydrogen peroxide, lipid peroxidation, and electrolyte leakage in both genotypes. The activities of defensive antioxidant enzymes like superoxide dismutase, catalase, ascorbate peroxidase, glutathione reductase, and glutathione S-transferase were also increased with increasing Cd concentrations; however, the increase in AG-10 was greater than in AP-3. The accumulation of phenols was decreased with Cd stress in both pea genotypes, with the greatest decreases were observed in AP-3. In conclusion, Cd caused a marked reduction in growth, biomass yield, and pigment content in both pea genotypes. However, enhanced accumulation of osmolytes and antioxidant enzyme activities alleviated the adverse effects of Cd. AG-10 was more tolerant genotype than AP-3, as AG-10 showed less Cd induced damage and higher antioxidant enzyme activities.

Generating Private Data Surrogates for Vision Related Tasks

With the widespread application of deep networks in industry, membership inference attacks, i.e. the ability to discern training data from a model, become more and more problematic for data privacy. Recent work suggests that generative networks may be robust against membership attacks. In this work, we build on this observation, offering a general-purpose solution to the membership privacy problem. As the primary contribution, we demonstrate how to construct surrogate datasets, using images from GAN generators, labelled with a classifier trained on the private dataset. Next, we show this surrogate data can further be used for a variety of downstream tasks (here classification and regression), while being resistant to membership attacks. We study a variety of different GANs proposed in the literature, concluding that higher quality GANs result in better surrogate data with respect to the task at hand.
Are We Ready for Fragile X Newborn Screening Testing?—Lessons Learnt from a Feasibility Study

Fragile X syndrome (FXS) is the most prevalent heritable cause of cognitive impairment but is not yet included in a newborn screening (NBS) program within Australia. This paper aims to assess the feasibility and reliability of population screening for FXS using a pilot study in one hospital. A total of 1971 mothers consented for 2000 newborns to be tested using routine NBS dried blood spot samples. DNA was extracted and a modified PCR assay with a chimeric CGG primer was used to detect fragile X alleles in both males and females in the normal, premutation, and full mutation ranges. A routine PCR-based fragile X assay was run in parallel to validate the chimeric primer assay. Babies with CGG repeat number ≥59 were referred for family studies. One thousand nine hundred and ninety NBS samples had a CGG repeat number less than 55 (1986 < 50); 10 had premutation alleles >54 CGG repeats (1/123 females and 1/507 males). There was complete concordance between the two PCR-based assays. A recent review revealed no clinically identified cases in the cohort up to 5 years later. The cost per test was $AUD19. Fragile X status can be determined on routine NBS samples using the chimeric primer assay. However, whilst this assay may not be considered cost-effective for population screening, it could be considered as a second-tier assay to a developed immunoassay for fragile X mental retardation protein (FMRP).
Prevalence and pattern of internet addiction among medical students, Bengaluru

The term Internet Addiction was proposed by Dr. Ivan Goldberg in 1995 for pathological compulsive internet use. 1 Internet addiction commonly refers to an individual’s inability to control his or her use of the internet, which eventually causes one’s marked distress and functional impairment in daily life. 2 Currently internet has become the source of entertainment, education, communication etc. and also for both legal and illegal activities. In the past five years use of social media has increased tremendously more so among the young. Currently (2016), there are 462 million active internet users in India. India stood second on the ranking of ABSTRACT

Provenance of Triassic sandstones in the basins of Northern Ireland—Implications for NW European Triassic palaeodrainage

Palaeodrainage models for the mixed fluvial‐aeolian systems, which supplied detritus to Triassic basins on and offshore Britain and Ireland are well established. Basins such as those across Northern Ireland are not as well understood. Provenance studies of Triassic sandstones in the Slyne Basin offshore western Ireland and in basins west of Shetland have indicated that sediment supply was through a southward flowing fluvial system. Similar work on Triassic sandstones in the Wessex and East Irish Sea basins on and offshore Britain identified source rocks to the south supporting models, which evoke the northward flowing “Budleighensis” river system. The basins across Northern Ireland are potentially situated along the drainage divide between these two large‐scale drainage systems. K‐feldspar Pb‐isotopic analysis, apatite U–Pb geochronology and trace element geochemistry identify the Hebridean Platform, and the Scottish and Irish massifs to the north and west, respectively, and the remnant Variscan Uplands to the far south of the basins as source areas. The proportion of the northern‐ and southern‐derived detritus fluctuates several times over the sampled intervals, suggesting the dominance of drainage systems supplying sand to the basins “switched” intermittently over time. This may be due to abnormally heavy rains periodically powering the Budleighensis river system farther north or perhaps localised subsidence temporarily disconnecting Triassic basins on and offshore Britain and Ireland. The Triassic basins in Northern Ireland acted as either a major drainage divide between southern and northern river systems or as a regional sink for sediment preventing further expansion of either system.
Polygenic background modifies penetrance of monogenic variants conferring risk for coronary artery disease, breast cancer, or colorectal cancer

Genetic variation can predispose to disease both through (i) monogenic risk variants in specific genes that disrupt a specific physiologic pathway and have a large effect on disease risk and (ii) polygenic risk that involves large numbers of variants of small effect that affect many different pathways. Few studies have explored the interaction between monogenic risk variants and polygenic risk.We identified monogenic risk variants and calculated polygenic scores for three diseases, coronary artery disease, breast cancer, and colorectal cancer, in three study populations — case-control cohorts for coronary artery disease (UK Biobank; N=12,879) and breast cancer (Color Genomics; N=19,264), and an independent cohort of 49,738 additional UK Biobank participants.In the coronary artery disease case-control cohort, increased risk for carriers of a monogenic variant ranged from 1.3-fold for those in the lowest polygenic score quintile to 12.6-fold for those in the highest. For breast cancer, increased risk ranged from 2.4 to 6.9-fold across polygenic score quintiles. Among the 49,738 UK Biobank participants who carried a monogenic risk variant, the probability of disease at age 75 years was strongly modified by polygenic risk. Across individuals in the lowest to highest percentiles of polygenic risk, the probability of disease ranged from 17% to 78% for coronary artery disease; 13% to 76% for breast cancer; and 11% to 80% for colon cancer.For three important genomic conditions, polygenic risk powerfully modifies the risk conferred by monogenic risk variants.
