Towards accurate models for predicting smartphone applications’ QoE with data from a living lab study
Authors: De Masi Alexandre , Wac Katarzyna 
Published: October 2020

AbstractProgressively, smartphones have become the pocket Swiss army knife for everyone. They support their users needs to accomplish tasks in numerous contexts. However, the applications executing those tasks are regularly not performing as they should, and the user-perceived experience is altered. In this paper, we present our approach to model and predict the Quality of Experience (QoE) of mobile applications used over WiFi or cellular network. We aimed to create predictive QoE models and to derive recommendations for mobile application developers to create QoE aware applications. Previous works on smartphone applications’ QoE prediction only focus on qualitative or quantitative data. We collected both qualitative and quantitative data “in the wild“ through our living lab. We ran a 4-week-long study with 38 Android phone users. We focused on frequently used and highly interactive applications. The participants rated their mobile applications’ expectation and QoE and in various contexts resulting in a total of 6086 ratings. Simultaneously, our smartphone logger (mQoL-Log) collected background information such as network information, user physical activity, battery statistics, and more. We apply various data aggregation approaches and features selection processes to train multiple predictive QoE models. We obtain better model performances using ratings acquired within 14.85 minutes after the application usage. Additionally, we boost our models’ performance with the users expectation as a new feature. We create an on-device prediction model with on-smartphone only features. We compare its performance metrics against the previous model. The on-device model performs below the full features models. Surprisingly, among the following top three features: the intended task to accomplish with the app, application’s name (e.g., WhatsApp, Spotify), and network Quality of Service (QoS), the user physical activity is the most important feature (e.g., if walking). Finally, we share our recommendations with the application developers, and we discuss the implications of QoE and expectations in mobile application design.

Published: October 2020

AbstractA new drilling system was developed by the US Ice Drilling Program (IDP) to rapidly drill through overlying ice to collect subglacial rock cores. The Agile Sub-Ice Geological (ASIG) Drill system is capable of drilling up to 700 m of ice in a continuous manner. Intermittent ice core samples can be taken as needed. Ten-plus meters of subglacial bedrock and unconsolidated, frozen sediment cores can be drilled with wireline core retrieval. The functionality of the drill system was demonstrated in 2016–17 at the Pirrit Hills, Antarctica where 8 m of high-quality, continuous granite core was retrieved beneath 150 m of ice. The particulars of the drill system development, features and performance are discussed.
Large deviations and central limit theorems for sequential and random systems of intermittent maps
Authors: NICOL MATTHEW , PEREIRA FELIPE PEREZ , TÖRÖK ANDREW 
Published: October 2020

AbstractWe obtain large and moderate deviation estimates for both sequential and random compositions of intermittent maps. We also address the question of whether or not centering is necessary for the quenched central limit theorems obtained by Nicol, Török and Vaienti [Central limit theorems for sequential and random intermittent dynamical systems.Ergod. Th. & Dynam. Sys.38(3) (2018), 1127–1153] for random dynamical systems comprising intermittent maps. Using recent work of Abdelkader and Aimino [On the quenched central limit theorem for random dynamical systems.J. Phys.A49(24) (2016), 244002] and Hella and Stenlund [Quenched normal approximation for random sequences of transformations.J. Stat. Phys.178(1) (2020), 1–37] we extend the results of Nicol, Török and Vaienti on quenched central limit theorems for centered observables over random compositions of intermittent maps: first by enlarging the parameter range over which the quenched central limit theorem holds; and second by showing that the variance in the quenched central limit theorem is almost surely constant (and the same as the variance of the annealed central limit theorem) and that centering is needed to obtain this quenched central limit theorem.
Prolonged incubation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in a patient on rituximab therapy

Published: October 2020

AbstractThe incubation period of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is rarely >14 days. We report a patient with hypogammaglobulinemia who developed coronavirus disease 2019 (COVID-19) with a confirmed incubation period of at least 21 days. These findings raise concern for a prolonged presymptomatic transmission phase, necessitating a longer quarantine duration in this patient population.

AbstractBackgroundThe prevalence of psychotic experiences (PEs) is higher in low-and-middle-income-countries (LAMIC) than in high-income countries (HIC). Here, we examine whether this effect is explicable by measurement bias.MethodsA community sample from 13 countries (N = 7141) was used to examine the measurement invariance (MI) of a frequently used self-report measure of PEs, the Community Assessment of Psychic Experiences (CAPE), in LAMIC (n = 2472) and HIC (n = 4669). The CAPE measures positive (e.g. hallucinations), negative (e.g. avolition) and depressive symptoms. MI analyses were conducted with multiple-group confirmatory factor analyses.ResultsMI analyses showed similarities in the structure and understanding of the CAPE factors between LAMIC and HIC. Partial scalar invariance was found, allowing for latent score comparisons. Residual invariance was not found, indicating that sum score comparisons are biased. A comparison of latent scores before and after MI adjustment showed both overestimation (e.g. avolition, d = 0.03 into d = −0.42) and underestimation (e.g. magical thinking, d = −0.03 into d = 0.33) of PE in LAMIC relative to HIC. After adjusting the CAPE for MI, participants from LAMIC reported significantly higher levels on most CAPE factors but a significantly lower level of avolition.ConclusionPrevious studies using sum scores to compare differences across countries are likely to be biased. The direction of the bias involves both over- and underestimation of PEs in LAMIC compared to HIC. Nevertheless, the study confirms the basic finding that PEs are more frequent in LAMIC than in HIC.
Fear, anger, and desire: Affect and the interactional intricacies of rape humor on a live podcast
Authors: Franzén Anna G. , Jonsson Rickard , Sjöblom Björn 
Published: October 2020

AbstractAggressive, sexist humor is often understood as expressions of inner, misogynist attitudes. This article, however, investigates rape humor as a collective and interactive phenomenon. Drawing on an infamous Swedish podcast episode, we illuminate rape humor in terms of affect, desire, and repression (Butler 1987; Billig 1999), and as such, how taboo-breaking arouses both pleasure and fear among the participants. The analyses detail affective practices that both promote and discipline affects. The men in the group interpellate one of the participants as a clown, someone whose taboo-breaking they interactionally support and simultaneously distance themselves from. The article concludes that affects, like subject positions, are interpellated in interaction. Building on Wetherell's (2013) understanding of affect as both discursive and embodied, we suggest a reintroduction of repression/desire into a discursively oriented framework.

Calibrate to innovate: Community age vectors and the real time incrementation of language change
Authors: Holmes-Elliott Sophie 
Published: October 2020

AbstractThis study investigates children's real time incrementation of language change as it is impacted by community-wide patterns of linguistic variability. The investigation combines apparent time analyses across an age-stratified sample of adult speakers, with real time analyses across a panel of speakers spanning childhood to adolescence. Three variables are analysed: GOOSE-fronting, a socially unmarked change; TH-fronting, a socially stigmatised, rapidly expanding change; and T-glottaling, a socially stigmatised, steadily shifting change. Variables are selected based on their social and generational profiles which present learners with more or less challenging community patterns to extract. Real time analyses confirm that community variance impacts on speakers’ ability to increment change in real time. Findings provide support for themomentum-basedmodel of language change and builds on Labov's (2012:267) theory of the ‘outward orientation’ of children, which views learners as capable of extracting age vectors from generational differences. (Language change, incrementation, real time, GOOSE-fronting, TH-fronting, T-glottaling)*
The Alzheimer case: perceptions, knowledge and the acquisition of information about Alzheimer's disease by middle-aged and older adults in Flanders

Published: October 2020

AbstractAlzheimer's disease (AD) is a major health concern as the world population ages. Yet, few studies have examined what the public over the age of 50 knows about AD. This qualitative study, based on 40 in-depth interviews, examines the knowledge of AD by Flemish people between 50 and 80 years old and their cross-source engagement with information sources. Building on AD media representations and theories on media complementarity and health information behaviour, we find that respondents mostly encounter AD information non-purposively via traditional mass media and interpersonal communication, while the internet is occasionally used to purposefully seek information. Novels, personal experiences/social proximity, public figures and particularly film stand out as channels and sources of AD information, suggesting that fictional narratives, personal experiences and being able to identify with others leave lasting impressions and help to communicate and disperse AD information. However, common misconceptions and gaps in knowledge persist, including AD being considered part of the normal ageing process and old age as well as confusing AD with Parkinson's disease. The biomedical perspective and the tragedy discourse prevail among the majority of respondents, who describe AD in terms of decline, loss and death and as ‘the beginning of the end’. Only a few, typically female respondents, appear aware of the role of individual health behaviour and lifestyle choices to prevent dementia or delay its onset. The misconceptions of AD and gaps in knowledge, as well as the fact that a third of all cases of dementia might be delayed or prevented by managing lifestyle and other risk factors, stress the importance of public educational programmes and the need to emphasise and raise awareness of preventative behaviour. Overall, the findings from this study can be of help to public health communicators and dementia-awareness campaigns, as well as AD training programmes for health-care professionals and family care-givers.
Trochaic bias overrides stress typicality in English lexical development
Authors: HOFMANN Klaus , BAUMANN Andreas 
Published: October 2020

AbstractThis paper investigates whether typical stress patterns in English nouns and verbs are available as a prosodic cue for categorisation and accelerated word learning during first language acquisition. The stress typicality hypothesis states that left-stressed nouns and right-stressed verbs should be acquired earlier than the reverse configurations if stress effectively signals lexical class membership. In this view, class-typical stress patterns are expected to facilitate learning of novel items. A series of generalized additive models (GAMs) based on a comprehensive set of lexical data (CELEX) as well as a large set of age-of-acquisition (AoA) and concreteness ratings reveals that stress typicality plays a minor role in early acquisition, as it is generally superseded by a preference for left-hand (or ‘trochaic’) patterns in both nouns and verbs. This may be explained by general cognitive constraints (perceptual salience and recency) or exposure to the dominant pattern in the ambient language.
Popular differences for corners in Abelian groups
Authors: BERGER AARON 
Published: October 2020

AbstractFor a compact abelian group G, a corner in G × G is a triple of points (x, y), (x, y+d), (x+d, y). The classical corners theorem of Ajtai and Szemerédi implies that for every α > 0, there is some δ > 0 such that every subset A ⊂ G × G of density α contains a δ fraction of all corners in G × G, as x, y, d range over G.Recently, Mandache proved a “popular differences” version of this result in the finite field case $G = {\mathbb{F}}_p^n$, showing that for any subset A ⊂ G × G of density α, one can fix d ≠ 0 such that A contains a large fraction, now known to be approximately α4, of all corners with difference d, as x, y vary over G. We generalise Mandache’s result to all compact abelian groups G, as well as the case of corners in $\mathbb{Z}^2$.

Published: October 2020

AbstractIn order to realize the online allocation of collaborative processing resource of smart workshop in the context of cloud manufacturing, a multi-objective optimization model of workshop collaborative resources (MOM-WCR) was proposed. Considering the optimization objectives of processing time, processing cost, product qualification rate, and resource utilization, MOM-WCR was constructed. Based on the time sequence of workshop processing tasks, the workshop collaborative manufacturing resource was integrated in MOM-WCR. Fuzzy analytic hierarchy process (FAHP) was adopted to simplified the multi-objective problem into the single-objective problem. Then, the improved firefly algorithm which integrated the particle swarm algorithm (IFA-PSA) was used to solve MOM-WCR. Finally, a group of connecting rod processing experiments were used to verify the model proposed in this paper. The results show that the model is feasible in the application of workshop-level resource allocation in the context of cloud manufacturing, and the improved firefly algorithm shows good performance in solving the multi-objective resource allocation problem.
Is This Pa Chay Vue? A Study in Three Frames
Authors: MICHAUD JEAN 
Published: October 2020

AbstractThree archival photographs recently made public by the French National Library depict men associated with an event taking place in colonial Laos around 1920. However, upon examination of the pictures and textual sources, combined with contemporaneous documents, it turns out that the pictures are actually from Tonkin (colonial northern Vietnam) and may depict Batchai (Pa Chay Vue) a celebrated Hmong messiah in 1918 when he met with colonial authorities in an ultimate negotiation attempt before launching a four-year rebellion. Batchai famously led a violent revolt against Tai and French power in Tonkin and Laos between 1918 and 1921, which has been documented in French military reports. No photograph has ever been found of the rebel leader and his supporters and this find in itself would be of significance, especially for the Hmong diaspora in the West for whom Pa Chay Vue has achieved near-mythical status as a major folk hero. This article examines whether or not this is him; but beyond the simple task of identification, it proposes interpretations for the events that suggest a more complex affair than French military archives have ever been willing to tell, including the hypothesis of an administrative cover up.
The missing focus on women’s health in the First 1,000 days approach to nutrition
Authors: Kinshella Mai-Lei Woo , Moore Sophie E , Elango Rajavel 
Published: October 2020

AbstractThe First 1,000 Days approach highlights the time between conception and a child’s second birthday as a critical period where adequate nutrition is essential for adequate development and growth throughout the child’s life and potentially onto their own offspring. Based on a review of relevant literature, this commentary explores the First 1,000 Days approach with a maternal lens. While the primary objective of the First 1,000 Days approach to nutrition is to reduce child malnutrition rates, particularly chronic undernutrition in the form of stunting, interventions are facilitated through mothers in terms of promoting healthy behaviours such as exclusive breast-feeding and attention to her nutritional status during pregnancy and lactation. Though these interventions were facilitated through women, women’s health indicators are rarely tracked and measured, which we argue represents a missed opportunity to strengthen the evidence base for associations between maternal nutrition and women’s health outcomes. Limited evidence on the effects of dietary interventions with pregnant and lactating mothers on women’s health outcomes hinders advocacy efforts, which then contributes to lower prioritisation and less research.
Dietary health perceptions and sources of nutritional knowledge in an urban food environment: a qualitative study from Indonesia
Authors: Colozza David 
Published: October 2020

AbstractObjective:To investigate dietary health understandings, healthy foods access perceptions and the main sources of nutritional knowledge of residents in three urban communities of varying socio-economic make-up.Design:An ethnographic approach to primary qualitative data collection, involving frequent visits to study areas over 4 months and in-depth interviews. Interviews were recorded, transcribed verbatim and analysed through an iterative approach.Setting:Yogyakarta, Indonesia.Participants:A purposive sample of 45 participants divided equally among the 3 communities. Participants were mostly female (93 %), aged between 27 and 75 years (mean 47·7) and largely identified as the person responsible for household food-related decisions (93 %).Results:Three overarching themes emerged: (i) dietary health understandings; (ii) healthy foods access perceptions and (iii) sources of nutritional knowledge. Participants employed multifaceted conceptualisation of dietary health. Most identified healthy foods with traditional plant-based foods, inexpensive and locally available from multiple sources. Thus, all participants perceived healthy foods as highly available in the local environment and most (80 %) as affordable. Reported affordability issues referred to specific foods (particularly animal source products) and were independent of income levels. Participants acquired nutritional knowledge from multiple sources, including many community-based initiatives. These were overall perceived as useful, but also as presenting some limitations.Conclusions:The variety in dietary health understandings reported by study participants, and their high perceptions of healthy foods availability in the local environment reinforce the idea that individual- and food environment-level determinants of nutritional behaviours are highly contextual.
Impacts of Oceanic Mixed Layer on Hurricanes: A Simulation Experiment With Hurricane Sandy
Authors: Li Siqi , Chen Changsheng , Wu Zhongxiang , Beardsley Robert C. , Li Ming 
Published: October 2020

AbstractInfluences of the ocean mixed layer (OML) dynamics on intensity, pathway, and landfall of October 2012 Hurricane Sandy were examined through an experiment using the Weather Research and Forecasting (WRF) model. The WRF model was run for two cases with or without coupling to the OML. The OML in the WRF was calculated by an oceanic mixed layer submodel. The initial conditions of the depth and mean water temperature of the OML were specified using Global‐FVCOM and Global‐HYCOM fields. The comparison results between these two cases clearly show that including the OML dynamics enhanced the contribution of vertical mixing to the air‐sea heat flux. When the hurricane moved toward the coast, the local OML rapidly deepened with an increase of storm wind. Intense vertical mixing brought cold water in the deep ocean toward the surface to produce a cold wake underneath the storm, with the lowest sea temperature at the maximum wind zone. This process led to a significant latent heat loss from the ocean within the storm and hence rapid drops of the air temperature and vapor mixing ratio above the sea surface. As a result, the storm was intensified as the central sea level pressure dropped. Improving air pressure simulation with OML tended to reduce the storm size and strengthened the storm intensity and hence provided a better simulation of hurricane pathway and landfall.
3D-Printed electrochemical sensor-integrated transwell systems

Published: October 2020

AbstractThis work presents a 3D-printed, modular, electrochemical sensor-integrated transwell system for monitoring cellular and molecular events in situ without sample extraction or microfluidics-assisted downstream omics. Simple additive manufacturing techniques such as 3D printing, shadow masking, and molding are used to fabricate this modular system, which is autoclavable, biocompatible, and designed to operate following standard operating protocols (SOPs) of cellular biology. Integral to the platform is a flexible porous membrane, which is used as a cell culture substrate similarly to a commercial transwell insert. Multimodal electrochemical sensors fabricated on the membrane allow direct access to cells and their products. A pair of gold electrodes on the top side of the membrane measures impedance over the course of cell attachment and growth, characterized by an exponential decrease (~160% at 10 Hz) due to an increase in the double layer capacitance from secreted extracellular matrix (ECM) proteins. Cyclic voltammetry (CV) sensor electrodes, fabricated on the bottom side of the membrane, enable sensing of molecular release at the site of cell culture without the need for downstream fluidics. Real-time detection of ferrocene dimethanol injection across the membrane showed a three order-of-magnitude higher signal at the membrane than in the bulk media after reaching equilibrium. This modular sensor-integrated transwell system allows unprecedented direct, real-time, and noninvasive access to physical and biochemical information, which cannot be obtained in a conventional transwell system.
