Main maximum power point tracking strategies intended for photovoltaics

This paper presents evaluations among the most usual MPPT techniques, doing meaningful comparisons with respect to the amount of energy extracted from the photovoltaic panel (PV) (Tracking Factor - TF) in relation to the available power, PV voltage ripple, dynamic response and use of sensors. Using MatLab/Simulink® and DSpace platforms, a digitally controlled boost DC-DC converter was implemented and connected to an Agilent Solar Array E4350B simulator in order to verify the analytical procedures. The main experimental results are presented and a contribution in the implementation of the IC algorithm is performed and called IC based on PI. Moreover, the dynamic response and the tracking factor are also evaluated using a Friendly User Interface, which is capable of online program power curves and compute the TF. Finally, a typical daily insulation is used in order to verify the experimental results for the main PV MPPT methods.
Additive effects of trans-10, cis-12 conjugated linoleic acid and propionic acid on milk fat content and composition in dairy cows

Diet is a relatively simple way to modify milk fat yield and composition in dairy cows as the end-products of digestion are precursors or inhibitors of milk fat synthesis. The individual effects of these end-products are well-known, but it is still not known whether these nutrients have an additive effect or an interaction effect on milk fat secretion. Thus our objective was to investigate the effects of two of these nutrients on milk fat secretion, trans-10, cis-12 conjugated linoleic acid (CLA) and propionic acid (C3) supplied alone or together, under the same experimental conditions. Four Holstein dairy cows were used in a 4×4 Latin square design with 14-d periods. Treatments were control, CLA (duodenal infusion of 1·85 g/d of trans-10, cis-12 CLA), C3 (ruminal infusion of 500 g/d of C3) and CLA+C3 (duodenal infusion of 1·85 g/d of trans-10, cis-12 CLA plus ruminal infusion 500 g/d of C3). Infusions of trans-10, cis-12 CLA reduced milk fat content and yield by 18% whereas C3 infusions had no significant effect on milk fat secretion. Trans-10, cis-12 CLA decreased the yields of all milk fatty acids (FA). This reduction was proportionally greater for FA synthesized de novo than for preformed long-chain FA. Infusions of C3 decreased the yields and percentages of 4:0 and 18:0 and increased the yields and percentages of all odd-chain FA. Interactions between trans-10, cis-12 CLA and C3 infusions on milk fat content, yield and FA composition were never significant. Overall, this study showed that trans-10, cis-12 CLA has different and greater effects on milk fat secretion than C3. Moreover, under our experimental conditions, their effects on milk FA yields, which reflect their effects on mammary lipogenesis, were additive, whatever their individual effect.
Notetaking in non-academic settings: a review

There is considerable research on notetaking in academic settings but relatively little of it in non-academic ones. This paper reviews the effects of notetaking in legal situations, counselling and interviewing, and assesses the usefulness of notetaking as a memory aid for older people and as a prospective memory device for brain-injured persons. The results suggest that: notetaking has no significant effect on recall in ‘real-life’ jury situations; there is some evidence that notetaking by counsellors in counselling sessions might be harmful for clients; there is some evidence that notetaking in interviews can reduce bias in decision making; there is some evidence that notetaking is helpful for older persons; and that too little research has been conducted on the use of notetaking as a device for aiding the prospective memory for brain-injured persons to reach any firm conclusions. The general limitations of the research are reviewed and implications for future work considered. Copyright © 2002 John Wiley & Sons, Ltd.
A Double Standard in Death? Gender Differences in Obituaries

Male/female differences in aging-related issues may extend beyond individuals' actual lives. Gender differences in 869 obituaries, death notices, and memorials were examined. Males, compared to females, had significantly more lines describing careers. Support was also found for a possible double standard in obituary pictures; while pictures were more likely to be included in male than female obituaries, the discrepancy between actual age and estimated pictured age was significantly greater for women than men. This greater emphasis on careers for men and younger appearance for women in obituaries parallels gendered expectations for adult men and women in our society.
Clinical multicentre study of citalopram compared double-blindly with mianserin in depressed patients in Finland

Ahlfors UG, Elovaara S, Harma P, Suoniemi I, Heikkila L, Nummi K, Vartiainen A, Var-tiainen H, Tarnminen T, Elgen K, Sundman K. Clinical multicentre study of citalopram compared double-blindly with mianserin in depressed patients in Finland.The aim of the trial was to study the antidepressant effect and side effects of citalopram and mianserin in a double-blind, multicentre study in six psychiatric hospitals in Finland. Patients of both sexes, aged 18 to 70 years, were included. The depression was classified as endogenous or non-endogenous by means of the Newcastle Depression Scale (1). Thirty-seven patients were allocated to treatment with citalopram and 34 to treatment with mianserin. Six patients (5+1) did not fulfil the inclusion criteria and nine patients (4+5) dropped out of the study. Citalopram. 40-60 mg daily, and mianserin, 60-90 mg daily, were given once a day in the evening for 4 weeks. The patients were assessed before treatment and after 1, 2, and 4 weeks. The Clinical Global Impression Scal.
Multi-output RNN-LSTM for multiple speaker speech synthesis with α-interpolation model

Deep Learning has been applied successfully to speech processing. In this paper we propose an architecture for speech synthesis using multiple speakers. Some hidden layers are shared by all the speakers, while there is a specific output layer for each speaker. Objective and perceptual experiments prove that this scheme produces much better results in comparison with sin- gle speaker model. Moreover, we also tackle the problem of speaker interpolation by adding a new output layer (a-layer) on top of the multi-output branches. An identifying code is injected into the layer together with acoustic features of many speakers. Experiments show that the a-layer can effectively learn to interpolate the acoustic features between speakers.
Variations in intensity, fundamental frequency, and voicing for teachers in occupational versus nonoccupational settings.

PURPOSE In this study, the authors created a more concise picture of the vocal demands placed on teachers by comparing occupational voice use with nonoccupational voice use. METHOD The authors used National Center for Voice and Speech voice dosimetry databank to calculate voicing percentage per hour as well as average dB SPL and fundamental frequency (F(0)). Occupational voice use (9:00 a.m.-3:00 p.m., weekdays) and nonoccupational voice use (4:00 p.m.-10:00 p.m., weekends) were compared (57 teachers, 2 weeks each). RESULTS Five key findings were uncovered: (1) Similar to previous studies, occupational voicing percentage per hour is more than twice that of nonoccupational voicing; (2) teachers experienced a wide range of occupational voicing percentages per hour (30+/-11% per hr); (3) average occupational voice was about 1 dB SPL louder than the nonoccupational voice and remained constant throughout the day; (4) occupational voice exhibited an increased pitch and trended upward throughout the day; and (5) some apparent gender differences were shown. CONCLUSIONS Data regarding voicing percentages, F(0), and dB SPL provide critical insight into teachers' vocal health. Further, because nonoccupational voice use is added to an already overloaded voice, it may add key insights into recovery patterns and should be the focus of future studies.
From policy to practice: engaging and embedding the third mission in contemporary universities

Purpose – Over the past 20 years public policy has sought to promote and formalise the socio‐economic role of universities under the auspices of the so called “third mission”. The purpose of this paper is to consider how the third mission relates to, and has the capacity to reinforce the core missions of teaching and research.Design/methodology/approach – By highlighting the key limitations of contemporary debate the paper bridges the conceptual model/case‐study dichotomy that characterises the literature. The paper draws on an ongoing study of higher education institutions in the UK and Europe.Findings – The paper contends that triangulating teaching, research, and third stream activities reinforces the respective dynamics of each component through their recursive and reciprocal development.Research limitations/implications – The paper forms the foundations of a de novo research agenda to better understand the dynamics of the third mission as a central facet of the contemporary university.Practical impli.
Organizational Citizenship Behaviors of Pharmacy Faculty: Modeling Influences of Equity Sensitivity, Psychological Contract Breach, and Professional Identity

The purpose of this paper is to develop a model that defines the impact of psychological contract breach, identity salience, and equity sensitivity on organizational citizenship behavior (OCB) of pharmacy faculty. Using social exchange and social identity theories, we develop a model and propose the potential relationships among model constructs. Our theory-based model posits that equity sensitivity will have direct effects on OCB and will also moderate the relationships between contract breach, identity salience, and the performance of OCB. This paper provides university and pharmacy school leadership teams insight into the potential predictors of job performance of pharmacy faculty members.
FA*IR: A Fair Top-k Ranking Algorithm

In this work, we define and solve the Fair Top-k Ranking problem, in which we want to determine a subset of k candidates from a large pool of n » k candidates, maximizing utility (i.e., select the "best" candidates) subject to group fairness criteria. Our ranked group fairness definition extends group fairness using the standard notion of protected groups and is based on ensuring that the proportion of protected candidates in every prefix of the top-k ranking remains statistically above or indistinguishable from a given minimum. Utility is operationalized in two ways: (i) every candidate included in the top-k should be more qualified than every candidate not included; and (ii) for every pair of candidates in the top-k, the more qualified candidate should be ranked above. An efficient algorithm is presented for producing the Fair Top-k Ranking, and tested experimentally on existing datasets as well as new datasets released with this paper, showing that our approach yields small distortions with respect to rankings that maximize utility without considering fairness criteria. To the best of our knowledge, this is the first algorithm grounded in statistical tests that can mitigate biases in the representation of an under-represented group along a ranked list.
Event-Related Potentials in Substance Use Disorders

Mechanisms that mediate the transition from occasional, controlled, drug use to the impaired control that characterizes severe dependence are still a matter of investigation. The etiology of substance use disorders (SUDs) is complex, and in this context of complexity, the concept of “endophenotype,” has gained extensive popularity in recent years. The main aim of endophenotypes is to provide a simpler, more proximal target to discover the biological underpinnings of a psychiatric syndrome. In this view, neurocognitive and neurophysiological impairments that suggest functional impairments associated with SUDs have been proposed as possible endophenotypes. Because of its large amplitude and relatively easy elicitation, the most studied of the cognitive brain event-related potentials (ERPs), the P300 component, has been proposed as one possible candidate. However, if a P300 amplitude alteration is a common finding in SUDs, it is also observable in other psychiatric afflictions, suggesting that the associations found may just reflect a common measure of brain dysfunction. On this basis, it has been proposed that a multivariate endophenotype, based on a weighted combination of electrophysiological features, may provide greater diagnostic classification power than any single endophenotype. The rationale for investigating multiple features is to show that combining them provides extra useful information that is not available in the individual features, leading ultimately to a multivariate phenotype.The aim of the present article is to outline the potential usefulness of this kind of “combined electrophysiological procedure” applied to SUDs. We present a review of ERP studies, combining data from people with SUD, family members, and normal control subjects, to verify whether the combination of 4ERPs (P50, MMN, P300, and N400) may produce profiles of cortical anomalies induced by different types of SUD (alcohol vs cocaine vs cannabis vs heroin).
“Why Should I Feel Guilty?”: Reflections on the Workings of Guilt in White‐Aboriginal Relations

Statements by various public figures that White people ought not to feel guilty about Aboriginal dispossession, and although many Australians assert that they feel no guilt in the matter, this paper asserts that White attitudes to the Australian Aboriginal people are strongly influenced by guilt. The nature of a guilt that ostensibly does not and ought not exist is examined. Persecutory and depressive aspects of guilt are considered, and the history of a two-factor theory of guilt in the psychoanalytic literature is outlined. The workings of the two types of guilt are charted in the group dynamics of a psychology class studying Aboriginal issues.
Losing the rose tinted glasses: neural substrates of unbiased belief updating in depression

Recent evidence suggests that a state of good mental health is associated with biased processing of information that supports a positively skewed view of the future. Depression, on the other hand, is associated with unbiased processing of such information. Here, we use brain imaging in conjunction with a belief update task administered to clinically depressed patients and healthy controls to characterize brain activity that supports unbiased belief updating in clinically depressed individuals. Our results reveal that unbiased belief updating in depression is mediated by strong neural coding of estimation errors in response to both good news (in left inferior frontal gyrus and bilateral superior frontal gyrus) and bad news (in right inferior parietal lobule and right inferior frontal gyrus) regarding the future. In contrast, intact mental health was linked to a relatively attenuated neural coding of bad news about the future. These findings identify a neural substrate mediating the breakdown of biased updating in major depression disorder, which may be essential for mental health.
Human Spatial Representation: Insights from Animals

Since the work of Tolman [1], many psychologists have argued that mammalian navigation depends on internal representations that are enduring, geocentric, and comprehensive: 'cognitive maps' of the environment. Suggestive evidence for cognitive maps came from studies of rodents, who systematically explore novel environments, detect displaced landmarks, and take new paths between familiar locations [1–3]. More recently, however, much of the mammalian spatial behavior that was attributed to cognitive maps has been found to depend on representations of quite a different sort: representations that are dynamic, egocentric, and limited to a restricted subset of environmental information. Here we review briefly research on navigating animals from ants to primates and then turn to research on human navigation. We suggest that momentary, egocentric, and limited representations underlie much of human spatial behavior, including aspects of human navigation that have been taken as paradigmatic evidence for cognitive maps. We focus on three systems that underlie navigation in diverse animals: (1) a path integration system that operates by dynamic updating, (2) a place recognition system that operates by template matching of viewpoint-dependent representations of landmarks, and (3) a reorientation system that operates by congruence-finding on representations of the shape of the surface layout. After reviewing the evidence for these systems from studies of animal navigation, we consider evidence for these systems from studies of humans. Finally, we ask what might account for the special character of human navigation. Path integration is a process by which the relation of the animal to one or more significant places in the environment is updated continuously as the animal moves. For example, the position of the nest relative to a foraging animal changes as the animal moves through the environment. By representing the nest's egocentric position as a vector, specifying both the radial direction and the distance of the nest from the animal's current position and heading, and by continuously subtracting from it a second vector specifying the direction and distance traveled from the last moment of updating to the current one, the resulting vector corresponds to the current egocentric position of the home. (Alternatively, the nest could be represented as the origin of a geocentric coordinate system, the ant's current position represented as a vector specifying its distance and direction from the nest, and updating could occur by vector addition. With one fixed and one changing position, these two representational schemes are equivalent.) Path integration has been found …
Visualization of a Copper Wire Explosion in Atmospheric Pressure Air

Experimental and computational images of a 90-μm thick copper wire explosion in atmospheric pressure air are presented. A Marx generator is used to produce a pulsed current density into the wire with a maximum rate of rise of ~ 1018 Am-2 s-1. A multiphase numerical model includes mass and momentum conservation equations, thermofield ionization, Maxwell's equations, and heat transfer between the phases. Visual records of the experiment agree with the simulation results.
Tooth whitening effects on bracket bond strength in vivo.

OBJECTIVE To test the hypothesis that there is no difference between the bracket survival rate of brackets bonded to bleached and unbleached teeth. MATERIALS AND METHODS Thirty-eight patients who required comprehensive orthodontic treatment were included in the study. A split mouth technique was used with one arch exposed to in-office whitening gel containing 38% hydrogen peroxide for 30 minutes, while the unbleached arch served as the control. Patients were divided into two groups: Brackets bonded within 24 hours after bleaching and brackets bonded 2-3 weeks after bleaching. The bracket survival rate was computed using the log-rank test (Kaplan-Meier Analysis). RESULTS A significantly higher rate of bracket failure was found with bleached teeth (16.6%) compared with unbleached teeth (1.8%) after 180 days. Brackets bonded within 24 hours of bleaching resulted in significantly higher clinical failure (14.5%) compared with those bonded after 3 weeks (2.1%). Adhesive Remnant Index scores of failed brackets revealed that the majority of failure in bleached teeth occurred in the enamel/resin interface. CONCLUSIONS The hypothesis was rejected. Brackets bonded within 24 hours after bleaching have a significantly higher risk for bond failure. Orthodontic bonding should be delayed for 2-3 weeks if patients have a history of in-office bleaching with 38% hydrogen peroxide.
"They Must Be Working Hard": An (Auto-)Ethnographic Account of Women's Artistic Gymnastics

This article includes narrative excerpts compiled from field notes the author collected observing six Australian women's elite artistic gymnasts and their two coaches. Using creative nonfiction and auto-ethnography, the stories' plots describe the gymnasts' daily training realities and include personal reflections on the author's gymnastics experiences and reactions to what she saw during the observations. The stories illustrate how, despite differing levels of authority, the coaches', gymnasts', and parts of her own identity and behaviors are shaped by a dominant gymnastics model. This ideal coerces the coaches and gymnasts to regulate their selves and behaviors according to its dominant characteristics. Although potentially beneficial and satisfactory, the training model's discourses and practices can have debilitating effects.
Place status, place loyalty and well being: an exploratory investigation of Israeli residents

Purpose – The purpose of the current exploratory study is to examine whether place status (ordinary or prestigious) and place loyalty can be related to personal well being (measured by happiness and self‐esteem). Design/methodology/approach – Data were collected through a field survey with 150 respondents.Findings – Significant differences were found between residents of prestigious versus ordinary communities. Among those who perceive their community as ordinary, the paper found no relationship between place loyalty and self esteem, and a marginally significant negative relationship between place loyalty and happiness. In contrast, among those who perceive their community as prestigious, the paper found a positive relationship between place loyalty and happiness, and a marginally significant positive relationship between place loyalty and self esteem.Research limitations/implications – The present study is based on a rather small non‐representative sample. As it is unclear whether place loyalty predicts h.
Evaluation of a Wound Dressing Composed of Hyaluronic Acid and Collagen Sponge Containing Epidermal Growth Factor in Diabetic Mice

Abstract This study investigated the effect of a wound dressing composed of hyaluronic acid (HA) and collagen (Col) sponge containing epidermal growth factor (EGF) on wound healing in diabetic mice. High-molecular-weight (HMW) HA aqueous solution, hydrolyzed low-molecular-weight (LMW) HA aqueous solution and heat-denatured Col aqueous solution were mixed, followed by freeze-drying to obtain a spongy sheet. Cross-linkage between Col molecules was induced by UV irradiation to the spongy sheet (Type-I wound dressing). In a similar manner, a spongy sheet containing EGF (Type-II wound dressing) was prepared by freeze-drying the mixed solution of HMW-HA, LMW-HA and Col containing EGF. The efficacy of these products was evaluated in type-II diabetic BKS.Cg-+Leprdb/+Leprdb (db/db) mice. Wound dressings were applied to a full-thickness, dorsal skin defect measuring 1.5 cm × 2.0 cm, showing adipose tissue. In the control group, a commercially available artificial dermis composed of collagen spongy sheet (TERUDERMIS®) was used. A commercially available polyurethane film dressing (Bioclusive®) was applied over each wound dressing. After 1 week of application, wound conditions were evaluated based on their gross and histological appearances. Type-I and -II wound dressings promoted a decrease in wound size associated with angiogenesis and granulation tissue formation, compared with the artificial dermis. In particular, Type-II wound dressings promoted sufficient re-epithelialization. These findings indicate that the combination of HA, Col and EGF promotes wound healing by stimulating cell activity including cell migration and proliferation on the adipose tissue in a diabetic wound. Type-I and -II wound dressings would be useful to prepare a well-vascularized wound bed acceptable for split-thickness auto-skin grafting.
