Deep Learning based Large Scale Visual Recommendation and Search for E-Commerce

In this paper, we present a unified end-to-end approach to build a large scale Visual Search and Recommendation system for e-commerce. Previous works have targeted these problems in isolation. We believe a more effective and elegant solution could be obtained by tackling them together. We propose a unified Deep Convolutional Neural Network architecture, called VisNet, to learn embeddings to capture the notion of visual similarity, across several semantic granularities. We demonstrate the superiority of our approach for the task of image retrieval, by comparing against the state-of-the-art on the Exact Street2Shop dataset. We then share the design decisions and trade-offs made while deploying the model to power Visual Recommendations across a catalog of 50M products, supporting 2K queries a second at Flipkart, India's largest e-commerce company. The deployment of our solution has yielded a significant business impact, as measured by the conversion-rate.
Ammonia Flux from Open-Lot Dairies: Development of Measurement Methodology and Emission Factors

Abstract Ammonia emissions contribute to the formation of secondary particulate matter (PM) and violations of the National Ambient Air Quality Standard. Ammonia mass concentration measurements were made in February 1999 upwind and downwind of an open-lot dairy in California, using a combination of active bubbler and passive filter samplers. Ammonia fluxes were calculated from concentrations measured at 2, 4, and 10 m above ground at three locations on the downwind edge of the dairy, using micrometeorological techniques. A new method was developed to interpolate fluxes at six additional locations from ammonia concentrations measured at a single height, providing measurements at sufficient spatial resolution along the downwind border of the dairy to account for the heterogeneity of the source. PM measured up- and downwind of the dairy demonstrated insignificant ammonium particle formation in the immediate vicinity of the dairy and negligible contribution of dissociated ammonium nitrate to measured ammonia concentrations. Ammonium nitrate concentrations measured downwind of the dairy ranged from 26 to 0.26 μg m−3 and from 2 to 43% of total PM2.5 mass concentrations. Measured ammonia fluxes showed that liquid manure retention ponds represented relatively minor sources of ammonia in winter on the dairy studied. Ammonia emission factors derived from the measurements ranged from 19 to 143 g head−1 day−1, showing an increase with warmer, drier weather and a decrease with increased relative humidity and lower temperatures.
Intermediate Representations in Spoken Word Recognition; Evidence from Word Illusions

A new paradigm that may be appropriate for uncovering speech perceptual codes is presented. Illusory words (e.g., (bijou, /bi[formula]u/) are detected (Experiments 1 and 2) or spontaneously identified (Experiment 3) by blending two dichotic stimuli (e.g., /bit[formula]-k[formula][formula]u/). According to the logic of illusory conjuctions, the speech property involved in such illusions must be separately registered as an independent entity in the course of the recognition process. In addition, the design allows comparison of different properties by the manipulation of the distribution of information between the two inputs (e.g., for initial consonant, /ki[formula]u-b[formula]t[formula]/; for first vowel /b[formula][formula]u-kit[formula]/). The results show that illusory word targets are more frequently experienced when the distribution corresponds to syllables than when it corresponds to either the initial consonant (and its phonetic features) of the first vowel. Illusory words are also more frequent when the distribution corresponds to syllables than when it does not correspond to any obvious phonological property (e.g., /b[formula]tu-ki[formula][formula]/). Moreover, in the identification task, illusory percepts only involve syllable combinations. These results extend previous observations of a major role of the syllable as a segmentation unit in French.
Exploring Language Stereotypes in Post‑colonial Hong Kong through the Matched-guise Test

After the change of sovereignty in Hong Kong from Britain to China on July 1st, 1997, the status of Putonghua (the language of the new Chinese ruler) has been formally recognized in addition to Cantonese (the vernacular language) and English (the international and ex-colonizer’s language). Four years after the political handover, a Matched-guise test was conducted on a total of 1048 local Hong Kong Secondary 4 students. The aim of this study was to ascertain the respondents’ subjective reactions towards the three languages when the city was undergoing significant political and socio-economic changes. The results showed that the Cantonese guise was rated the highest on traits of solidarity, the English guise the highest on traits of power, whereas the Putonghua guise was rated the lowest in both dimensions. Although the study started from a micro perspective investigating the attitudes of the respondents towards the three target languages and their speakers, the research results helped to reveal the vitality of the three target languages in post-colonial Hong Kong and suggest directions for language education.
Age differences in associative and strategic processes in human conditional learning

Research indicates associative and strategic deficits mediate age related deficits in memory, whereas simple associative processes are independent of strategic processing and strategic processes mediate resistance to interference. The present study showed age-related deficits in a contingency learning task, although older participants' resistance to interference was not disproportionately affected. Recognition memory predicted discrimination, whereas general cognitive ability predicted resistance to interference, suggesting differentiation between associative and strategic processes in learning and memory, and age declines in associative processes. Older participants' generalisation of associative strength from existing to novel stimulus–response associations was consistent with elemental learning theories, whereas configural models predicted younger participants' responses. This is consistent with associative deficits and reliance on item-level representations in memory during later life.
Goal-Attribute Compatibility in Consumer Choice

This research advances the notion that product evaluations are a function of the compatibility of consumers' goals with the attributes describing choice alternatives. Building on the concept of self-regulation, it is argued that attribute evaluations are moderated by individuals' goal orientation and, specifically, that attributes compatible with individuals' regulatory orientation tend to be overweighted in choice. This proposition is tested by examining the impact of goal orientation on consumer preferences in 3 different contexts: (a) hedonic versus utilitarian attributes, (b) performance versus reliability attributes, and (c) attractive versus unattractive (good vs. bad) attributes. The data show that prevention-focused individuals are more likely to overweight (in relative terms) utilitarian, reliability-related, and unattractive attributes than promotion-focused consumers, who are more likely to place relatively more weight on hedonic, performance-related, and attractive attributes. Considered together, these findings support the proposition that attributes compatible with individuals' goal orientation tend to be overweighted in choice.
Using an inpatient portal to engage families in pediatric hospital care

Objective: Assess parent use and perceptions of an inpatient portal application on a tablet computer that provides information about a child’s hospital stay. Methods: This cross-sectional study was conducted with parents of children hospitalized on a medical/surgical unit at a tertiary children’s hospital. From December 2014 to June 2015, parents were provisioned a tablet portal application to use throughout the hospitalization. The portal includes real-time hospital vitals, medications, schedules, lab results, education, health care team pictures/roles, and request and messaging functionalities. Portal use information was gathered from tablet metadata. Parents completed discharge surveys on portal satisfaction, use, and impact on their information needs, engagement, communication, error detection, and care safety and quality. Data were analyzed using descriptive statistics and qualitative content analysis. Results: Over 6 months, 296 parents used the portal, sending 176 requests and 36 messages. No tablets were lost or damaged. The most used and liked features included vitals, medication list, health care team information, and schedules. Overall, parent survey respondents (90) were satisfied with the portal (90%), reporting that it was easy to use (98%), improved care (94%), and gave them access to information that helped them monitor, understand, make decisions, and care for their child. Many parents reported that portal use improved health care team communication (60%). Most perceived that portal use reduced errors in care (89%), with 8% finding errors in their child’s medication list. Conclusions: Overall, parents were satisfied with the inpatient portal. Portals may engage parents in hospital care, facilitate parent recognition of medication errors, and improve perceptions of safety and quality.
Evaluation of hybrid MRAM/CMOS cells for reconfigurable computing

The main objective of this paper is to give an overview of different hybrid MRAM/CMOS cells to use in the context of reconfigurable computing. The way to convert magnetic information into an electrical one is not unique and we propose to compare different kind of hybrid cells. These hybrid cells can be used to define structures as Look-up Table, configuration memory point, Flip-flop and other basic elements needed to define programmable logic. Even if these cells were designed for the TAS (Thermally Assisted Switching) MRAM technology, it is possible to adapt them to more advanced technologies such as STT (Spin Transfer Torque).
Paving Consensus: Enacting, Challenging, and Revising the Consensus Process in a Cohousing Community

This study focused on a cohousing community's use of consensus to make a decision about surfacing a parking area. It revealed that the community's use of consensus decision making allowed the residents to balance three goals: making an appropriate decision, meeting members’ needs, and maintaining the community's well-being. Reaching agreement, however, was complicated by members’ value differences and discontinuity in their participation. The analysis of this case reveals three qualities characteristic of the enactment of consensus: the role of structured communication within and between group meetings, a tension between maintaining process openness and reaching decision closure, and the expectation that group members will work within the consensus process. The analysis also highlights the importance of timing in the interpretation of conflict in a consensus-oriented group and the role of process change when a group reaches the limits of members’ commitment to consensus.
Environmental perceptions, attitudes and priorities: cross‐cultural implications for public policy

Presents the findings of a cross‐cultural analysis of perceived risks of environmental, technological, and societal problems. An international sample of 295 undergraduate and graduate students at three US universities and the National Taiwan University was surveyed. The study was designed to test two hypotheses: first, that today’s university students have grown numb to threat warnings and second, that differences in cultural and political contexts result in variation in the way societies perceive environmental issues and social concerns. Analysis of variance tests identified a number of significant differences in the way US and Asian university students perceive environmental risks, despite the many similarities in the university‐student cultures of both regions.
Assessing the Al-Anon Component of Alcoholics Anonymous

There have been few outcome studies on the Al-Anon component of A.A. In a convenience sample of 50 A.A. members, this study found no significant difference on reported family stress scores (IFR) between those who had a family member attending Al- Anon and those who did not have a family member attending. However, a significant correlation was found between increased duration of family member Al-Anon attendance and lower reported family stress scores for the A.A. member and the Al-Anon member. Al-Anon attendance was also significantly related to continuous attendance of A.A. by the alcoholic.
Teaching assistant argumentativeness: Effects on affective learning and student perceptions of power use

This study examined effects of teaching assistant argumentativeness on student affective learning and perceptions of teacher power use. Significant differences were found in student affective learning for classes taught by low, moderate and high argumentative TAs. Lower TA argumentativeness is positively associated with student affective learning and vice versa. Significant differences were also found for student perceptions of instructor power use for classes taught by low, moderate, and high argumentative TAs. Lower TA argumentativeness is associated with higher levels of power use and vice versa. Multiple correlations revealed that TA and student argumentativeness accounted for 14% of the variance in student affective learning and for 15% of the variance in TA referent power use. Findings suggest that although high argumentative TAs may be “social specialists” in power use (and thus be perceived by students to use less power), their high levels of argumentativeness seem to have negative effects on stud.
Maternal overweight and obesity in early pregnancy and risk of infant mortality: a population based cohort study in Sweden

Objective To investigate associations between maternal overweight and obesity and infant mortality outcomes, including cause-specific mortality. Design Population based cohort study. Setting and participants 1 857 822 live single births in Sweden 1992–2010. Main outcome measures Associations between maternal body mass index (BMI) in early pregnancy and risks of infant, neonatal, and postneonatal mortality, overall and stratified by gestational length and by causes of infant death. Odds ratios were adjusted for maternal age, parity, smoking, education, height, country of birth, and year of delivery. Results Infant mortality rates increased from 2.4/1000 among normal weight women (BMI 18.5–24.9) to 5.8/1000 among women with obesity grade 3 (BMI ≥40.0). Compared with normal weight, overweight (BMI 25.0–29.9) and obesity grade 1 (BMI 30.0–34.9) were associated with modestly increased risks of infant mortality (adjusted odds ratios 1.25 (95% confidence interval 1.16 to 1.35) and 1.37 (1.22 to 1.53), respectively), and obesity grade 2 (BMI 35.0–39.9) and grade 3 were associated with more than doubled risks (adjusted odds ratios 2.11 (1.79 to 2.49) and 2.44 (1.88 to 3.17)). In analyses stratified by preterm and term births, maternal BMI was related to risks of infant mortality primarily in term births (≥37 weeks), where risks of deaths due to birth asphyxia and other neonatal morbidities increased with maternal overweight and obesity. Obesity grade 2–3 was also associated with increased infant mortality due to congenital anomalies and sudden infant death syndrome. Conclusions Maternal overweight and obesity are associated with increased risks of infant mortality due to increased mortality risk in term births and an increased prevalence of preterm births. Maternal overweight and obesity may be an important preventable risk factor for infant mortality in many countries.
Monodromy of a Class of Logarithmic Connections on an Elliptic Curve

The logarithmic connections studied in the paper are direct images of regular connections on line bundles over genus-2 double covers of the elliptic curve. We give an explicit parametrization of all such connections, determine their monodromy, differential Galois group and the underlying rank-2 vector bundle. The latter is described in terms of elementary transforms. The question of its (semi)-stability is addressed.
Iron Status and Helicobacter pylori Infection in Symptomatic Children: An International Multi-Centered Study

Objective Iron deficiency (ID) and iron deficiency anaemia (IDA) are global major public health problems, particularly in developing countries. Whilst an association between H. pylori infection and ID/IDA has been proposed in the literature, currently there is no consensus. We studied the effects of H. pylori infection on ID/IDA in a cohort of children undergoing upper gastrointestinal endoscopy for upper abdominal pain in two developing and one developed country. Methods In total 311 children (mean age 10.7±3.2 years) from Latin America - Belo Horizonte/Brazil (n = 125), Santiago/Chile (n = 105) - and London/UK (n = 81), were studied. Gastric and duodenal biopsies were obtained for evaluation of histology and H. pylori status and blood samples for parameters of ID/IDA. Results The prevalence of H. pylori infection was 27.7% being significantly higher (p<0.001) in Latin America (35%) than in UK (7%). Multiple linear regression models revealed H. pylori infection as a significant predictor of low ferritin and haemoglobin concentrations in children from Latin-America. A negative correlation was observed between MCV (r = −0.26; p = 0.01) and MCH (r = −0.27; p = 0.01) values and the degree of antral chronic inflammation, and between MCH and the degree of corpus chronic (r = −0.29, p = 0.008) and active (r = −0.27, p = 0.002) inflammation. Conclusions This study demonstrates that H. pylori infection in children influences the serum ferritin and haemoglobin concentrations, markers of early depletion of iron stores and anaemia respectively.
Study Strategies and Generative Learning: What Works?

One hundred nine college students participated in an experiment that involved reading a passage and responding to a 20-item multiple choice test. The students were randomly assigned to one of four groups. The four conditions involved reading and copying, reading and highlighting, reading and taking notes, and reading and generating questions. Students who generated questions performed better than two of the three other groups on the test. The authors attributed this improved performance to generative learning.
Identity and Development: Lessons Learned From a Blind Child

This article uses an analysis of speech to qualitatively examine the relationship between a blind child and his environment, his use of semiotic signs, and his identity development. A brief overview of development in blind children is followed by a case study. The theoretical construct of this article, which is interactionism, is infused into the case study to clearly connect theoretical arguments, assumptions, and interpretations to the speech material that is analyzed. Clinical implications and challenges are addressed in the “conclusion” section.
Associations of mortality with ocular disorders and an intervention of high-dose antioxidants and zinc in the Age-Related Eye Disease Study: AREDS Report No. 13.

OBJECTIVE To assess the association of ocular disorders and high doses of antioxidants or zinc with mortality in the Age-Related Eye Disease Study (AREDS). METHODS Baseline fundus and lens photographs were used to grade the macular and lens status of AREDS participants. Participants were randomly assigned to receive oral supplements of high-dose antioxidants, zinc, antioxidants plus zinc, or placebo. Risk of all-cause and cause-specific mortality was assessed using adjusted Cox proportional hazards models. RESULTS During median follow-up of 6.5 years, 534 (11%) of 4753 AREDS participants died. In fully adjusted models, participants with advanced age-related macular degeneration (AMD) compared with participants with few, if any, drusen had increased mortality (relative risk [RR], 1.41; 95% confidence interval [CI], 1.08-1.86). Advanced AMD was associated with cardiovascular deaths. Compared with participants having good acuity in both eyes, those with visual acuity worse than 20/40 in 1 eye had increased mortality (RR, 1.36; 95% CI, 1.12-1.65). Nuclear opacity (RR, 1.40; 95% CI, 1.12-1.75) and cataract surgery (RR, 1.55; 95% CI, 1.18-2.05) were associated with increased all-cause mortality and with cancer deaths. Participants randomly assigned to receive zinc had lower mortality than those not taking zinc (RR, 0.73; 95% CI, 0.61-0.89). CONCLUSIONS The decreased survival of AREDS participants with AMD and cataract suggests that these conditions may reflect systemic rather than only local processes. The improved survival in individuals randomly assigned to receive zinc requires further study.
OsJAR1 Contributes Mainly to Biosynthesis of the Stress-Induced Jasmonoyl-Isoleucine Involved in Defense Responses in Rice

Jasmonate plays key roles in plant growth and stress responses, as in defense against pathogen attack. Jasmonoyl-isoleucine (JA-Ile), a major active form of jasmonates, is thought to play a pivotal role in plant defense responses, but the involvement of JA-Ile in rice defense responses, including phytoalexin production, remains largely unknown. Here we found that OsJAR1 contributes mainly to stress-induced JA-Ile production by the use of an osjar1 Tos17 mutant. The osjar1 mutant was impaired in JA-induced expression of JA-responsive genes and phytoalexin production, and these defects were restored genetically. Endogenous JA-Ile was indispensable to the production of a flavonoid phytoalexin, sakuranetin, but not to that of diterpenoid phytoalexins in response to heavy metal stress and the rice blast fungus. The osjar1 mutant was also found to be more susceptible to the blast fungus than the parental wild type. These results suggest that JA-Ile production makes a contribution to rice defense responses with a great impact on stress-induced sakuranetin production.
