PocketFlow: An Automated Framework for Compressing and Accelerating Deep Neural Networks

Deep neural networks are widely used in various domains, but the prohibitive computational complexity prevents their deployment on mobile devices. Numerous model compression algorithms have been proposed, however, it is often dif-ﬁcult and time-consuming to choose proper hyper-parameters to obtain an efﬁ-cient compressed model. In this paper, we propose an automated framework for model compression and acceleration, namely PocketFlow. This is an easy-to-use toolkit that integrates a series of model compression algorithms and embeds a hyper-parameter optimization module to automatically search for the optimal combination of hyper-parameters. Furthermore, the compressed model can be converted into the TensorFlow Lite format and easily deployed on mobile devices to speed-up the inference. PocketFlow is now open-source and publicly available at https://github. om/Ten ent/Po ketFlow .
Dance Pedagogy: Myth Versus Reality

The teaching of ballet is steeped in tradition. As a dancer retires from the stage, he or she will often embark upon a teaching career in order to provide a continuation of that tradition for the next generation. It is not uncommon for the institutional tenets of training dance skills to be at odds with what is biomechanically sound and, therefore, unsafe for the dancer to repeat in daily technique class. Dance science had its beginnings in the late 1960s. Colleges and universities began to turn a serious eye to the analysis of the physical component of dancing. Rudimentary equipment, such as videography, has given way to very sophisticated movement analysis systems such as 7-camera motion capture systems. As the ability to “see” dance increases with more refined tools, teachers of dance in general and ballet in particular need to make anatomically sound corrections and unassailable decisions in the training of young dancers, as the technique class should be the first stop in injury prevention. This presentation touches on just a few of the discrepancies between what is taught and what is actually possible to achieve in the ballet class.
Can Caribbean coral populations be modelled at metapopulation scales

Understanding and predicting the connectivity of coral reef organisms linked by larval dispersal is a key goal of tropical coastal ecosystem science and management. As oceanographers make advances modelling transport processes between reefs, ecologists should be prepared to embrace the population dynamics of organisms at larger metapopulation scales. A metapopulation is demographically closed but contains multiple open local populations. Metapopulation models of coral dynamics would aid the identification of larval source and sink areas and help identify the boundaries of demographically closed populations. Metapopulation models would also aid the understanding of species extinctions and help formulate transboundary management strategies to conserve ecosystem function. Existing metapopulation models are not spatially realistic or proven to represent physical and biological processes at appropriate spatial and temporal scales. Before more realistic alternatives can be established, further research is needed into (1) the larval transport between reefs (i.e. the coupling of reef-scale and oceanic models of water circulation, the pre-settlement mortality rates of larvae, and larval mobility in the water column), (2) the influence of larval supply on coral population dynamics at local (10s of kilometres) scales (i.e. processes of settlement behaviour, post-settlement mortality, and the pre-emption of space by algae), and (3) processes affecting the net fecundity of local populations (i.e. interactions of colony size, partial mortality rate, competition with algae, and the influence of habitat, physical disturbance, herbivore pressure, nutrification and sedimentation).
Assessment of urban solid waste logistics systems: the case of Kampala, Uganda

Many cities, especially in developing countries, are facing challenges in the management of solid waste. The aim of the study was to develop effective logistics systems for solid waste management in urban areas of developing countries, with a specific focus on Kampala, Uganda. This thesis contains an assessment of the reverse logistics systems that enable effective recapturing of valuable products from urban solid waste. The study mapped the waste collection systems in Kampala using a geographic information system (GIS), i.e. ArcGIS software, and examined the existing models of waste collection to the final disposal destinations. It was found that food and yard wastes constitute 92.7 % of the waste that reaches landfills in Kampala. Recyclables and other special wastes constitute only 7.3 % of the total waste. The generation rate of solid wastes on average from poor areas, upscale wealthier areas, business centres and market areas was 582, 169, 105 and 90 tonnes/day respectively. The study optimised travel distances, number of vehicles and collection time, while maximising total waste collection for environmental sustainability. Results showed that, an increase from a 6-tonne truck to a 10-tonne one reduced the travel distance by 39 %, while an increase from a 10-tonne truck to an 18-tonne truck reduced the travel distance by 34 % considering the current 40 % waste collection. Suggestions regarding the best waste collection routes and a suitable vehicle fleet and capacity to be used by Kampala Capital City Authority (KCCA) have been provided in this study. The research study further developed an overview of reverse logistics at the Kiteezi landfill. The study analysed in detail the collection, re-processing, re-distribution and final markets of these products into a reversed supply chain network of products delivered to the landfill. Of the products at the Kiteezi landfill, 14 % was channelled into the reverse chain, 63 % could be included in the distribution chain but were left out and disposed of while the remaining 23 % was buried straightaway. The main conclusion of the work was that solid waste management in Kampala is characterised by inefficient collection methods, insufficient coverage of the collection system and improper disposal of municipal solid waste. The existing system pertaining to reverse logistics suffers from unfavourable economics and legislative, technical and operational constraints that affect the recycling rate in Kampala compared to developed countries. This study presented large-scale data that can be used to improve solid waste management in other cities in developing countries.
POPs in hazardous waste incineration

Toxic effects of POPs can include cancer, allergies and damage to the central and peripheral nervous systems. Some POPs are endocrine disruptors, meaning that they affect systems in the human body that are controlled by hormones. In this way, they can cause sexual development problems, brain development problems, feminizing of males etc. Because cell growth and differentiation during the development of a foetus is regulated by hormones, a foetus is very sensitive to chemicals that affect the hormonal balances. Therefore, doses of endocrine disruptors that have no effect on the mother can cause severe birth defects.
Consumer willingness to pay for animal welfare attributes in a developing country context: The case of chicken in Nairobi, Kenya

In developing countries, especially in sub-Saharan Africa, policy makers have been reluctant to formulate animal welfare policies. This is despite potential benefits of such policies including increased domestic and global consumers’ demand for products that are compliant with humane treatment of animals. This study employed a choice experiment method to establish consumer willingness to pay (WTP) for animal welfare attributes in chicken. Data were drawn from 200 chicken consumers in Nairobi, Kenya and estimated using a random parameter logit model. The results indicate that consumers were willing to pay a premium for humanely-treated chicken. The consumers had a positive and significant preference for use of certified transportation means, humanely slaughtered chicken and animal welfare labelling. However, the consumers showed a negative preference for use of antibiotics in chicken production. These findings are vital for formulation of product differentiation strategies in the industry as well as food policy.
A comparison of 103–105 year uplift rates on the South Alkyonides Fault, central Greece: Holocene climate stability and the formation of coastal notches

Measurements of Holocene coastal notch sequences exposed in the footwall of the active South Alkyonides normal fault, Greece, reveal 3 Holocene paleoshorelines near the lateral fault tip, rising in elevation eastward toward the center of the fault, where a 4th paleoshoreline appears. The implied eastward increase in Holocene uplift rate mirrors that for an uplifted Quaternary marine terrace (0.29 mm/yr–0.55 mm/yr from west to east). Assuming these uplift rates were constant through the Holocene, notch elevations predict ages of 650, 1900, 3700 and 6500 years B.P., comparable with published 14C ages on notch fauna, and well correlated with periods of relatively stable Holocene climate. We propose that the notch sequences formed when post‐glacial sea level rise became outpaced by the coastal uplift rate, whilst individual notches formed when stable climate facilitated sustained erosion. The parity of the Holocene and Quaternary uplift rates suggests that notch sequences could be used to characterize long‐term patterns of uplift, slip‐rate and seismic hazards on active normal faults, if 6500 years is long enough to fully characterize temporal variation in the seismic cycle.
HERMITIAN WEIGHTED COMPOSITION OPERATORS ON WEIGHTED HARDY SPACES

Weighted composition operators have been related to products of composition operators and their adjoints and to isometries of Hardy spaces. In this paper, Hermitian weighted composition operators on weighted Hardy spaces of the unit disk are studied. In particular, necessary conditions are provided for a weighted composition operator to be Hermitian on such spaces. On weighted Hardy spaces for which the kernel functions are (1 − wz)−κ for κ ≥ 1, the Hermitian weighted composition operators are explicitly identified and, in some cases, their spectra are described. In addition, as a consequence of the properties of weighted composition operators, we compute the extremal functions for certain invariant subspaces of the Bergman space.
Enlarging the chemical space of anti-leishmanials: a structure–activity relationship study of peptoids against Leishmania mexicana, a causative agent of cutaneous leishmaniasis

Peptoids, a class of peptide mimetics, have emerged as promising anti-infective agents against a range of bacterial and fungal infections. Recently we have shown peptoids to be novel anti-parasitic and, specifically, anti-leishmanial, compounds. In this study, we have expanded the chemical space of our peptoid library and have identified peptoids with low micromolar activity against Leishmania mexicana axenic amastigotes and significantly, the first peptoids with promising activity against intracellular amastigotes, which are the clinical cause of cutaneous leishmaniasis.
A Method for Developing Seismic Intensity Maps from Twitter Data

Aim of this article, is to present a methodology for extracting macroseismic intensity information and producing seismic intensity maps from VGI (volunteered geographic information). As a VGI source for obtaining and assessing macroseismic observations, the authors chose twitter. Our methodology is validated in two recent earthquakes occurred in Greece: the January 26, 2014 ML = 5.8 in Kefallinia, and the November 17, 2014 ML = 5.2 in Evoikos. Twitter data published within the first 6 h, 12 h, 24 h and 48 h after the earthquake occurrence were analyzed to develop seismic intensity maps. Those maps were evaluated through intensity maps for the same earthquakes, published by international institutes. Evaluation results provide a strong empiric evidence for the credibility of our methodology, the accuracy of the produced seismic intensity maps and accentuate VGI, generated by twitter, as an adequate alternative source for collecting macroseismic information.
Effect of Electron Beam Irradiation on the Bacterial Load and Sensorial Quality of Sliced Cantaloupe

: Electron beam irradiated sliced cantaloupe was tested for 21 d of storage for total aerobic microbial counts, texture, color, and different sensorial parameters as a function of irradiation doses 0, 0.7, and 1.4 kGy and the wash treatments, 1 and 200 ppm chlorine applied to the melons before cutting. Irradiation resulted in a reduction in the total aerobic microbial counts with increasing doses. Melons washed only with water before cutting had total aerobic bacterial counts of 4.0, 2.0, and 0.8 log colony-forming units (CFU)/g on day 0 at irradiation doses of 0, 0.7, and 1.4 kGy, respectively. Across all doses of irradiation, counts were consistently lower for cantaloupe pieces obtained from melons that had been subjected to chlorine rinse in comparison with those washed with water without chlorine. Melons washed with chlorine before cutting had total aerobic bacterial counts of 2.7, 0.7, and 0.5 log CFU/g on day 0 at irradiation doses of 0, 0.7, and 1.4 kGy, respectively. Objective color analysis indicated no significant effect of irradiation on the color of cantaloupe. Texture measured as compression force was lower only for cantaloupe irradiated at 1.4 kGy. Irradiation did not affect descriptive attribute flavor and texture sensory attributes of cantaloupe pieces. Decontamination of whole cantaloupes before cutting using chlorine wash may be combined with low-dose irradiation for shelf-life extension of sliced cantaloupe.
Editorial: Effective Use of APA Style in Manuscript Preparation

One of the challenges for researchers in the social sciences is staying current in their fields of study. Several decades ago, Noland (1970) noted the difficulty of staying current, arguing that the social sciences literature was scattered throughout a variety of publication outlets. If staying current was a problem then, it is certain that today’s technological advancements (e.g., creation of Internet-based materials), in addition to a general knowledge explosion within the social sciences, make currency a challenge for even the most astute of scholars. Researchers are also faced with changes in social policy that affect their ability to work with human subjects (i.e., participants) and regular shifts in the issues that are deemed worthy of research and/or for which external research funding is available. Finally, researchers must stay current with changes in research reporting and writing conventions. These changes may be as minimal as shifts in preferred terminology used within a given field or as sweeping as requirements that older vague or misleading language (e.g., stating that the test is reliable) be replaced with more methodologically accurate language (e.g., test scores are reliable) so as to avoid miscommunication or misunderstandings about research. Collectively, these trends and changes in the field often result in the creation of standards governing the quality of research within a field of scholarship (e.g., American Educational Research Association, 2002, 2006). Changes in research reporting are frequently captured in writing style guides. While publications featuring educational research use a variety of style guides, the Publication Manual of the American Psychological Association (APA) is one of the most commonly accepted standards within the discipline. Indeed, according to Henson (2001), 66.5% of educational journals use APA style. In this editorial we offer guidelines for use of APA style in preparing manuscripts for educational journals. Following a brief history of the evolution of the current Publication Manual, we offer guidelines for employing APA style in four specific areas: (a) basic writing style and mechanics, (b) referencing of sources, (c) methodological considerations, and (d) reporting of quantitative data. It is hoped that these guidelines will aid authors who desire to submit manuscripts to Research in the Schools and other educational journals.
Correlation of Immunoexpression of E-Cadherin and Vascular Endothelial Growth Factor to Histopathology Gradation and Enlargement Regional Lymph Node in Oral Squamous Cell Carcinoma

Introduction: Oral Squamous Cell Carcinoma (OSCC)is the most common factor of secondary infection in the head and neck. Changes in the expression function of both E-Cadherin and Vascular Endothelial Growth Factor (VEGF) genes are known to provide an increased chance of invasion, metastasis and tumor growth. Immunohistochemistry immune techniques are known to examine the expression of tumor-linked gene proteins (immunoexpression) with a high degree of cellular accuracy. Method: A total of 30 body tissue subjects were selected from patients of Anatomical Pathology Faculty of Medicine Universitas Padjadjaran-Hospital Dr. Hasan Sadikin Bandung. Subsequently prepared using immunohistochemistry principles to test the correlation of histopathology gradation and immunoexpression of both E-Cadherin and VEGF. This cross sectional study with secondary data was retrospective and then evaluated correlation ofboth immunoexpressions of E-Cadherin and VEGF. Correlation using Correlation Rank Spearman with significance p <0,05. Results: There was a negative correlation (rs=-0.522) and significant (p <0.005) between E-Cadherin and histopathology gradations of OSCC. Results also showed no significant correlation between immunoexpression of both E-Cadherin and VEGF to enlargement of lymph nodes regional of OSCC. Conclusion: Oral Squamous Cell Carcinoma . Either E-Cadherin or VEGF is unrelated in enlargement of regional lymph nodes of Oral Squamous Cell Carcinoma.
Quantitative RT-PCR luminometric hybridization assay with an RNA internal standard for cytokeratin-19 mRNA in peripheral blood of patients with breast cancer

Objectives: To develop a highly sensitive quantitative RT-PCR hybridization assay for the determination of CK-19 mRNA in peripheral blood of patients with breast cancer. Patients and methods: Quantification of CK-19 mRNA was based on the coamplification of CK-19 mRNA with a recombinant CK-19 RNA internal standard (CK-19 RNA-IS) through RT-PCR. The biotinylated amplification products were immobilized on steptavidin coated wells, hybridized with digoxigenin labeled probes and determined through an antidigoxigenin antibody conjugated to alkaline phosphatase by luminometric detection. The developed luminometric hybridization assay was validated with samples containing total RNA of known amounts from CK-19 expressing cells (MCF-7) in the presence of 1 g total RNA isolated from peripheral blood mononuclear cells (PBMC) of healthy controls and a constant amount of CK-19 RNA-IS. The method was applied for the quantitative determination of CK-19 mRNA in the peripheral blood of 26 healthy volunteers, 14 patients with stage IV breast cancer and 37 patients with stage I/II breast cancer before chemotherapy. Results: Luminescence ratios for CK-19 mRNA and CK-19 RNA-IS were linearly related to the number of MCF-7 cells within the range of 1 to 2000 cells. The overall reproducibility of the assay (between-run) varied between 8.9% and 13.4%. The method can clearly detect CK-19 mRNA from 1 MCF-7 cell in the presence of 10 normal PBMC and is highly specific as none of the 26 healthy controls tested had detectable CK-19 mRNA levels, while 10 out of 14 (71.4%) and 9 out of 37 (24.3%) patients with stage IV and stage I/II breast cancer, respectively, were tested positive. Conclusion: The developed quantitative RT-PCR hybridization assay for CK-19 is reproducible, highly sensitive and specific, and can be used for a large-scale prospective evaluation of clinical samples. © 2002 The Canadian Society of Clinical Chemists.

Quality Control of Sachet-Packaged Drinking Water Sold in Primary Schools and Dantokpa Market in Cotonou

The Republic of Benin has an important population growth of nearly 3% and urban development in recent years counting 44.8% of the total population (2017) with an estimated urbanization rate of 3.55% per year (2015-2020) [1]. This development is one of the causes of the lifestyle change of citizens living in big cities. In recent years, this has led to the proliferation of sachet-packaged drinking water locally called "pure water" in Beninese cities, including Cotonou, the economic capital. This new category of drinking water is well appreciated by populations [2] because they are practical, refreshing, low cost and well presentable [3]. It is established that better access to safe drinking water can translate into tangible health benefits. But, water can also be the cause of diseases and cause of death [4].
Hepatitis B NAT virus‐positive blood donors in the early and late stages of HBV infection: analyses of the window period and kinetics of HBV DNA

Background and Objectives The Japanese Red Cross (JRC) carries out nucleic acid amplification testing (NAT) for hepatitis B virus (HBV), hepatitis C virus (HCV) and human immunodeficiency virus‐1 (HIV‐1) by using a multiplex (MPX) reagent. Screening is undertaken on serologically negative units. In this study we characterized HBV NAT‐positive donations individually and analysed the window period and kinetics of HBV DNA, during acute infection, in follow‐up studies.
Sample variance and Lyman α forest transmission statistics

We compare the observed probability distribution function (PDF) of the transmission in the H i Lyman {$α$} forest, measured from the Ultraviolet and Visual Echelle Spectrograph (UVES) `Large Programme' sample at redshifts z = [2, 2.5, 3], to results from the gimic cosmological simulations. Our measured values for the mean transmission and its PDF are in good agreement with published results. Errors on statistics measured from high-resolution data are typically estimated using bootstrap or jackknife resampling techniques after splitting the spectra into chunks. We demonstrate that these methods tend to underestimate the sample variance unless the chunk size is much larger than is commonly the case. We therefore estimate the sample variance from the simulations. We conclude that observed and simulated transmission statistics are in good agreement; in particular, we do not require the temperature-density relation to be `inverted'.
