Authors: Bernaldo de Quirós Aragón Mónica , Labrador Encinas Francisco J. , Estupiñá Puig Francisco J. , Fernández Arias Ignacio
Published: April 2019

El objetivo de este trabajo fue analizar las diferencias entre los casos de corta (5-10 sesiones), media (10-18 sesiones) y larga duración (más de 18 sesiones) en variables sociodemográficas, clínicas y de tratamiento. Se analizaron los datos de 349 pacientes de la Clínica Universitaria de Psicología de la Universidad Complutense de Madrid (CUP-UCM), que habían terminado el tratamiento con éxito. El número de técnicas aplicadas durante la intervención fue la variable más discriminativa, seguida por la comorbilidad -haber recibido un tratamiento anterior- número de tratamientos anteriores y número de objetivos establecidos antes de la intervención. Los resultados señalan la importancia de identificar las técnicas más eficaces para cada problema u objetivo para reducir, en la medida de lo posible, la duración de las intervenciones sin disminuir su eficacia.

Authors: Villalta Paucar Marco Antonio , Martinic Valencia Sergio
Published: April 2019

Se analiza el discurso y práctica de docentes en la interacción didáctica de sala de clase asociada a tipos de exigencia cognitiva. Se utilizan técnicas cualitativas de análisis de contenido y análisis estadístico descriptivo de estructuras dialogales profesor-alumnos de 32 clases de ocho docentes con prácticas de enseñanza que promueven aprendizajes. Los resultados indican que los docentes eficaces en contextos sociales vulnerables: 1) explican reiteradamente los contenidos, 2) ordenan la presentación de contenidos en un proceso gradual de complejidad, 3) tienen dos objetivos: lograr aprendizajes y formar a los estudiantes en valores ciudadanos y 4) las estructuras dialogales de baja exigencia cognitiva son porcentualmente mayoritarias. Se discuten los resultados.
Rastreando en el pasado… formas de regular la felicidad, la tristeza, el amor, el enojo y el miedo
Authors: Retana Franco Blanca Estela , Sánchez Aragón Rozzana
Published: April 2019

La regulación emocional se refiere a las maneras de modular, inhibir, intensificar o disminuir la forma de reaccionar ante situaciones elicitadoras de emoción; esto, con el fin de que el individuo se adapte a su entorno. Este proceso se inicia en los primeros meses de vida, va creando pautas de interacción más o menos exitosas con otros individuos y se va a definir a la luz de la interacción, observación y presencia de los padres. Sobre este presupuesto, se exploró el impacto del conflicto o de la armonía entre los padres en las reacciones emocionales de 113 adultos mexicanos. Los resultados muestran que para las emociones positivas se encuentran una mayor apertura y expresividad, mientras que para las negativas, el ocultamiento y la falta de expresión.

Authors: Olivares José , Vera-Villarroel Pablo , Rosa Alcázar Ana Isabel , Kuhne Walter , Montesinos Luis , Pina José Antonio
Published: April 2019

In this report we examined the reliability and structural validity of the Chilean version of the Social Phobia and Anxiety Inventory, SPAI, (Turner, Beidel, Dancu y Stanley, 1989), using a sample of 1040 non clinical Chilean adolescents (range of age between 13 and 18 years). The structural validity analysis indicated the existence of two, clearly differentiated, subscales (Social Phobia and Agoraphobia) that explained 43.4% of the variance. The alpha reliability coefficients were very high in each one of the subscales. In spite of finding significant differences, for sex in both scales, the effect size was small. On the other hand, the age variable was significant in the social phobia scale but not in the agoraphobia one, but again the effect size was small. In general the results offer empirical evidence in support of the reliability and validity of the Chilean version of the Social Phobia and Anxiety Inventory.
Modelos bayesianos de inferencia psicológica: ¿cómo predecir acciones en situaciones de incertidumbre?
Authors: Taborda Osorio Hernando
Published: April 2019

Esta investigación examinó si la capacidad para predecir acciones en circunstancias de incertidumbre puede ser comprendida como un proceso de inferencia Bayesiana. Se llevaron a cabo dos experimentos, cada uno con un grupo diferente de estudiantes universitarios de cíclo básico. En ambos experimentos se presentó un video en donde un agente entraba a un laberinto para consumir alimento. La tarea de los participantes fue predecir cuál de cuatro entradas utilizaría el agente para ingresar a la parte interna del laberinto. Los resultados mostraron una correlación alta, significativa a un p<.01, entre las predicciones del modelo bayesiano y las respuestas de los participantes. Este hallazgo revela que la capacidad de predecir acciones implica la estimación de la probabilidad posterior de acuerdo con el modelo bayesiano propuesto.

Published: April 2019

El propósito de esta investigación fue establecer la existencia de diferencias de género en las relaciones con iguales y su relación con la conducta prosocial y antisocial en educación primaria, secundaria y superior. Los participantes fueron 464 niños y jóvenes de primaria (n = 140), secundaria (n = 200) y universidad (n = 124) instituciones educativas públicas y privadas de la ciudad de Valledupar (Colombia). Se recogió información de la relaciones entre iguales y la conducta prosocial y antisocial a través de nominaciones de compañeros. Se encontró que el género femenino tiende a ser más popular, mientras que el género masculino es más rechazado y excluido. Se hallaron correlaciones moderadas entre la conducta prosocial y antisocial y la preferencia y el impacto social. También que las mujeres son más prosociales y tienen mayor preferencia social en la primaria, pero la tendencia cambia en la universidad, donde los varones tienen mayor preferencia social y son más prosociales.

El grupo de comparación, fue inyectado con solución salina y a uno de los grupos experimentales se le administró NMDA y a los otros dos, dosis diferentes del péptido BLMP-101 (0.3, 3.0 ug/ul). Los resultados sugieren que el péptido BLMP-101 con dosis de 3.0 ug/ul, facilitan la memoria espacial, mejor que el NMDA.
Effects of Haloperidol on Responding Maintained with Food and Sucrose-Water
Authors: Aparicio Carlos F.
Published: April 2019

The “hedonic” value of reinforcers is mediated by dopamine. Accordingly, haloperidol diminishes the value of reinforcers, interfering with the emission of operant behaviors. Alternatively, interference with dopamine transmission leaves animals directed towards the consumption of food. Thus, reinforcers remain intact after the administration of haloperidol. We assessed these possibilities with two types of reinforcers, food-pellets and sucrose-water, delivered under multiple schedules of reinforcement. Lever presses maintained by food-pellets generally was higher than that maintained by sucrose-water. Haloperidol produced dose-related decreases in lever presses and obtained reinforcers. Differences in lever presses maintained by the two types of reinforcers were preserved across doses. Subcutaneous administrations of haloperidol were more potent in decreasing lever presses than intra-peritoneal administrations. Decreases in lever pressing were not necessarily accompanied by substantial reductions in obtained food-pellets and sucrose-water reinforcers; under the effects of haloperidol rats continued to produce a considerable number of both types of reinforcers.

Ethanol Stimulates Trehalose Production through a SpoT-DksA-AlgU-Dependent Pathway in Pseudomonas aeruginosa
Authors: Harty Colleen E. , Martins Dorival , Doing Georgia , Mould Dallas L. , Clay Michelle E. , Occhipinti Patricia , Nguyen Dao , Hogan Deborah A.
Published: April 2019

Pseudomonas aeruginosa
is often found with bacteria and fungi that produce fermentation products, including ethanol. At concentrations similar to those produced by environmental microbes, we found that ethanol stimulated expression of trehalose-biosynthetic genes and cellular levels of trehalose, a disaccharide that protects against environmental stresses. The induction of trehalose by ethanol required the alternative sigma factor AlgU through DksA- and SpoT-dependent (p)ppGpp. Trehalose accumulation also required AHL quorum sensing and occurred only in post-exponential-phase cultures. This work highlights how cells integrate cell density and growth cues in their responses to products made by other microbes and reveals a new role for (p)ppGpp in the regulation of AlgU activity.

Pullorum disease, an acute poultry septicemia caused by
Salmonella
Gallinarum biovar Pullorum, is fatal for young chickens and is a heavy burden on poultry industry. The pathogen is rare in most developed countries but still extremely difficult to eliminate in China. Efficient epidemiological surveillance necessitates clarifying the origin of the isolates from different regions and their phylogenic relationships. Genomic epidemiological analysis of 97
S
. Pullorum strains was carried out to reconstruct the phylogeny and transmission history of
S
. Pullorum. Further analysis demonstrated that functional gene loss and acquisition occurred simultaneously throughout the evolution of
S
. Pullorum, both of which reflected adaptation to the changing environment. The result of our study will be helpful in surveillance and prevention of pullorum disease.

Authors: Ollivier Luc , Renaud Emmanuelle , Gouders Dominique , Plantin Patrice
Published: April 2019

During the follow-up of a woman treated by radiotherapy for an in situ carcinoma of her left breast, radio-induced skin lesions were diagnosed. They appeared not to be simple radiodermatitis but radio-induced Sweet syndrome. Discussions were led on the benefit of completing the last session of radiotherapy for such a low-grade malignancy while considering the risk of complication from radio-induced disease. General and local corticotherapy rapidly eradicated the fever and asthenia, while the skin lesions disappeared gradually. Moreover, biological improvement was noticed. The presented features of Sweet syndrome are almost similar in their initial phase to the radiodermatitis that is seen in common medical conditions.
Mature teratoma containing carcinoid tumour arising within a fallopian tube
Authors: Preshaw Jessica , Sherpa Toshi , Pawade Joya , Vyas Sanjay
Published: April 2019

A 52-year-old woman with a background of vaginal hysterectomy for heavy menstrual bleeding underwent an elective laparoscopic adhesiolysis, left salpingo-oophorectomy for left-sided pelvic pain, and a right salpingectomy. Despite a grossly normal appearance, histology revealed a rare presentation of mature teratoma with insular carcinoid tumour arising from the left fallopian tube. Even though the salpingectomy was thought to be curative, the patient underwent a second operation to remove her remaining right ovary as a precaution against malignant spread. In light of limited information in such rare cases, counselling on best management and discussion of risks to guide patient decision making remains challenging.

Published: April 2019

A 48-year-old woman presented with bilateral non-pulsatile proptosis and ophthalmoplegia after 3 days following blunt orbital trauma. It was associated with fever, malaise and loss of vision in right eye. She was provisionally diagnosed with cavernous sinus thrombosis and was treated with intravenous antibiotics with no improvement. A subtle bruit was present on examination, and digital subtraction angiography revealed a right direct (type A) carotid-cavernous fistula (CCF). The patient underwent right coil embolisation of direct CCF. On follow-up at 4 months, her proptosis resolved completely and extraocular movements improved.
Improving communication of patient issues on transfer out of intensive care
Authors: Roberts Jessica Caroline , Johnston-Walker Lizzie , Parker Kim , Townend Katherine , Bickley James
Published: April 2019

The written medical handover document is frequently poor in quality and highly variable which raises concerns about patient safety. Intensive care unit (ICU) patients have complex medical and social issues which increases the risk of errors during ongoing hospital treatment. Our project team of four doctors and two nurses aimed to improve the documentation of patient problems as they leave the ICU.

A literature review and process mapping of both medical and nursing transfer documentation helped in understanding the current process. Current problems (CP) were defined as any patient issues which require ongoing thought, management or follow-up.

Our progress was tracked using a measure of the number of CPs listed in the free-text field titled ‘Current Problems’ in 50 medical transfer documents. This was graphed on a control chart showing a process in statistical control. Means and control limits were recalculated whenever a process shift occurred.

There was no relationship between the number of CPs listed and length of ICU stay, age of patient, or severity of illness on presentation (Acute Physiologic Assessment and Chronic Health Evaluation II score). An inter-relationship graph identified the key drivers which were amenable to change: (1) the doctors completing the clinical summary at the time of discharge did not have all the information readily available to them and (2) the doctors were uncertain of the types of problem which should be communicated.

Improvements were designed and trialled using Plan-Do-Study-Act cycles to address these two key drivers. At baseline, the average number of CPs per patient was 1.8. After implementation of a paper problem list at the patient bedside, with supporting education, the average increased to 2.7. This was further improved by the addition of a checklist of common patient problems. This increased the average to 3.85.

These improvements were permanently implemented and ongoing audits have shown sustained improvement using statistical process control methods.

Published: April 2019

The following essay outlines the intervention and presents a framework that will serve as a guide in the evaluation of the different effects of the Superblocks. Superblocks consist of amalgamations of blocks throughout the city, with the goal of improving the habitability of public spaces, advancing sustainable mobility, increasing urban green, and promoting residents’ participation and coresponsibility, while ultimately influencing residents’ health and health inequities. The evaluation framework considers the following aspects: the interventions implemented in the Superblock strategy, the changes that occur at neighbourhood and individual level and the population turnover as intermediate factors and finally the health outcomes. Inequity dimensions are also considered.

Published: April 2019

While 15% of adult-onset asthma is estimated to have an occupational cause, there has been evidence of a downward trend in occupational asthma incidence in several European countries since the start of this millennium. However, recent data from The Health and Occupation Reporting network in the UK have suggested a possible reversal of this downward trend since 2014. We present these data and discuss possible explanations for this observed change in incidence trend. A high index of suspicion of occupational causation in new-onset asthma cases continues to be important, whether or not the recently observed increase in occupational asthma incidence in the UK is real or artefactual.
Modelling microbial growth and biomass accumulation during methane oxidation in unsaturated soil
Authors: Feng Song , Leung Anthony Kwan , Liu Hong Wei , Ng Charles Wang Wai , Tan Wan Peng
Published: April 2019

Microbial aerobic methane oxidation (MAMO) affects methane emissions through landfill covers by not only consuming methane, but also causing biomass accumulation associated with bacterial growth. Although the reduction of soil porosity by biomass accumulation has been well recognized, most existing models ignore this effect when estimating MAMO efficiency. The present study proposes a newly improved theoretical model that could consider the effects of both microbial growth and biomass accumulation on MAMO during coupled water–gas–heat reactive transport in unsaturated soil. Comprehensive batch incubation tests were performed to determine the input parameters required. Part of a set of published experimental data was used to validate the new model, while the remainder of the dataset was used to evaluate the model predictability of soil–microbe interaction (i.e., class B prediction). When ambient temperature is relatively high (30 °C), ignoring biomass accumulation would lead to an overestimation of MAMO efficiency by more than three times. As the biomass accumulated in soil pores, the water permeability, gas permeability, and gas diffusion in the unsaturated soil reduced, consequently limiting the supply of oxygen to the bacteria for MAMO to take place.
In-plane free vibrations of multi-span transmission lines
Authors: Qi Liming , Xu Ameng , Liu Xiaohui
Published: April 2019

A theoretical method of in-plane mode and natural frequency of multi-span transmission lines is presented. The main idea is to establish moment balance equations of each insulator string and in-plane vertical motion equation of each span in multi-span section when the effect of conductor inertia component parallel to the chord on the additional horizontal tension of conductor is considered. The validity of theoretical mode and natural frequency is demonstrated by consistency with the numerical results of a typical five-span transmission line based on ABAQUS. It is shown that the mode of the five-span transmission line with a larger elasto-geometrical parameter exhibits asymmetrical shape that differed from those of single-span conductor. Considering the complexity of the theoretical expression, a simplified theoretical formulation of the modes and natural frequencies of multi-span transmission lines is obtained. Based on the curve of the frequency changing with the elasto-geometrical parameter, the various internal resonance conditions are discussed.

Published: April 2019

Fluorescence in situ hybridization (FISH) using oligonucleotides is a simple and convenient method for chromosome research. In this study, 34 of 46 previously developed oligonucleotides produced signals in barley. Together with two plasmid clones and one PCR-amplified cereal centromere repeat (CCS1) probe, 37 repetitive sequences were chromosomally located produced three types of signals covering different positions on the chromosomes. The centromeric and pericentric regions had a more complex genomic organization and sequence composition probably indicative of higher contents of heterochromatin. An efficient multi-plex probe containing eight oligonucleotides and a plasmid clone of 45S rDNA was developed. Thirty-three barley karyotypes were developed and compared. Among them, 11 irradiation-induced mutants of cultivar 08-49 showed no chromosomal variation, whereas 22 cultivar and landrace accessions contained 28 chromosomal polymorphisms. Chromosome 4H was the most variable and 6H was the least variable based on chromosome polymorphic information content (CPIC). Five polymorphic chromosomes (1H-2, 2H-1, 3H-3, 5H-2, and 6H-2) were dominant types, each occurring in more than 50% of accessions. The multi-plex probe should facilitate identification of further chromosomal polymorphisms in barley.
A High-Efficiency FPGA-Based Accelerator for Binarized Neural Network
Authors: Guo Peng , Ma Hong , Chen Ruizhi , Wang Donglin
Published: April 2019

Although the convolutional neural network (CNN) has exhibited outstanding performance in various applications, the deployment of CNN on embedded and mobile devices is limited by the massive computations and memory footprint. To address these challenges, Courbariaux and co-workers put forward binarized neural network (BNN) which quantizes both the weights and activations to [Formula: see text]1. From the perspective of hardware, BNN can greatly simplify the computation and reduce the storage. In this work, we first present the algorithm optimizations to further binarize the first layer and the padding bits of BNN; then we propose a fully binarized CNN accelerator. With the Shuffle–Compute structure and the memory-aware computation schedule scheme, the proposed design can boost the performance for feature maps of different sizes and make full use of the memory bandwidth. To evaluate our design, we implement the accelerator on the Zynq ZC702 board, and the experiments on the SVHN and CIFAR-10 datasets show the state-of-the-art performance efficiency and resource efficiency.
In-Network Distributed Least-Mean-Square Identification of Nonlinear Systems Using Volterra–Laguerre Model
Authors: Gupta Saurav , Kapgate Sachin N. , Sahoo Ajit Kumar
Published: April 2019

It is of great importance to model the behavior of nonlinear systems in a distributed fashion using wireless sensor networks (WSNs) because of its computation and energy-efficient data processing. However, least squares methods have been previously employed to estimate the parameters of Volterra model for modeling nonlinear systems. Still, it is more convenient and advantageous to use in-network distributed identification strategy for real-time modeling and control. In this context, a black-box model with generalized structure and remarkable modeling ability called Volterra–Laguerre model is considered in which distributed signal processing is employed to identify the nonlinear systems in a distributed manner. The model cost function is expressed as a separable constrained minimization problem which is decomposed into augmented Lagrangian form to facilitate the distributed optimization. Then, alternating direction method of multipliers is employed to estimate the optimal parameters of the model. Convergence of the algorithm is guaranteed by providing its mean stability analysis. Simulation results for a nonlinear system are obtained under the noisy environment. These results are plotted against the results of noncooperative and centralized methods, demonstrating the effectiveness and superior performance of the proposed algorithm.

Published: April 2019

In this paper, we perform a numerical analysis of the effective temperature extracted from the deviations from the fluctuation dissipation theorem in a system of active Brownian spherical particles with excluded volume interactions. We show that, in the low density homogeneous phase at fixed Péclet number, the effective temperature decreases when the density of the system is increased. We compare this trend to the one found in the literature with simulations of other active models.

Subprojectivity domains of pure-projective modules
Authors: Durğun Yılmaz
Published: April 2019

In a recent paper, Holston et al. have defined a module [Formula: see text] to be [Formula: see text]-subprojective if for every epimorphism [Formula: see text] and homomorphism [Formula: see text], there exists a homomorphism [Formula: see text] such that [Formula: see text]. Clearly, every module is subprojective relative to any projective module. For a module [Formula: see text], the subprojectivity domain of [Formula: see text] is defined to be the collection of all modules [Formula: see text] such that [Formula: see text] is [Formula: see text]-subprojective. We consider, for every pure-projective module [Formula: see text], the subprojective domain of [Formula: see text]. We show that the flat modules are the only ones sharing the distinction of being in every single subprojectivity domain of pure-projective modules. Pure-projective modules whose subprojectivity domain is as small as possible will be called pure-projective indigent (pp-indigent). Properties of subprojectivity domains of pure-projective modules and of pp-indigent modules are studied. For various classes of modules (such as simple, cyclic, finitely generated and singular), necessary and sufficient conditions for the existence of pp-indigent modules of those types are studied. We characterize the structure of a Noetherian ring over which every (simple, cyclic, finitely generated) pure-projective module is projective or pp-indigent. Furthermore, finitely generated pp-indigent modules on commutative Noetherian hereditary rings are characterized.
FULLY AUTOMATIC DIGITAL FRINGE PROJECTION MEASUREMENT FOR 3D FACIAL SURFACE

Published: April 2019

Digital fringe projection technique is widely used in industrial applications with high accuracy and measurement speed. In this study, a fully automatic high-speed digital fringe projection technique is presented to profile 3D facial characteristics. The structured light with fringe pattern is used to be the light source in the measurement system and is projected by a digital light processing projector. The distorted fringe patterns from facial surface are captured by the digital camera. The absolute phase maps are calculated by using phase-shifting and quality guided path unwrapping algorithm. A complete, 3D facial feature is obtained by our measurement. We achieved simultaneous phase acquisition, reconstruction and three-dimensional (3D) exhibition at a speed of 0.5[Formula: see text]s. This technique may provide a high accuracy and real-time 3D facial measurement for biometric verification.
A new peak fitting method for 1D solid-state 29Si NMR spectra based on singular spectrum analysis
Authors: Li Guiliang , Li Changjun , Wei Nan
Published: April 2019

[Formula: see text]Si Nuclear Magnetic Resonance (NMR) can measure the molecular structure of silicate in oilfield reinjection water. However, noise in [Formula: see text]Si NMR spectra (NMRS) affects the determination of silicate molecular structure type. To solve this problem, a new peak fitting method (Two-step Greedy-Singular Spectrum Analysis-Gaussian Fitting Method, TSG-SSA-GFM) is proposed in this paper. This method first uses TSG to determine the embedding dimension, then uses SSA to determine the characteristic peak position. Finally, GFM is used to calculate the molar ratio of characteristic peaks. The results show that TSG can quickly determine the embedding dimension and reduce computation by at least 50% vs. the global ergodic method. The mean deviation of characteristic peak positions determined by SSA is 0.07 ppm, while Discrete Wavelet Transform (DWT) and Empirical Mode Decomposition (EMD) cannot determine characteristic peaks of [Formula: see text]Si NMRS containing overlapping peak. The average [Formula: see text]-squared of Gaussian fitting of [Formula: see text]Si NMRS is 98.4% while Lorentzian is 90.6%. Therefore, this study provides an important method for quantitative analysis of [Formula: see text]Si NMRS.
Deeper investigation into the utility of functional class scoring in missing protein prediction from proteomics data
Authors: Zhao Yaxing , Sue Andrew Chi-Hau , Goh Wilson Wen Bin
Published: April 2019

Functional Class Scoring (FCS) is a network-based approach previously demonstrated to be powerful in missing protein prediction (MPP). We update its performance evaluation using data derived from new proteomics technology (SWATH) and also checked for reproducibility using two independent datasets profiling kidney tissue proteome. We also evaluated the objectivity of the FCS p-value, and followed up on the value of MPP from predicted complexes. Our results suggest that (1) FCS [Formula: see text]-values are non-objective, and are confounded strongly by complex size, (2) best recovery performance do not necessarily lie at standard [Formula: see text]-value cutoffs, (3) while predicted complexes may be used for augmenting MPP, they are inferior to real complexes, and are further confounded by issues relating to network coverage and quality and (4) moderate sized complexes of size 5 to 10 still exhibit considerable instability, we find that FCS works best with big complexes. While FCS is a powerful approach, blind reliance on its non-objective [Formula: see text]-value is ill-advised.

AIS-Clus: A Bio-Inspired Method for Textual Data Stream Clustering
Authors: Abid Amal , Jamoussi Salma , Hamadou Abdelmajid Ben
Published: April 2019

The spread of real-time applications has led to a huge amount of data shared between users. This vast volume of data rapidly evolving over time is referred to as data stream. Clustering and processing such data poses many challenges to the data mining community. Indeed, traditional data mining techniques become unfeasible to mine such a continuous flow of data where characteristics, features, and concepts are rapidly changing over time. This paper presents a novel method for data stream clustering. In this context, major challenges of data stream processing are addressed, namely, infinite length, concept drift, novelty detection, and feature evolution. To handle these issues, the proposed method uses the Artificial Immune System (AIS) meta-heuristic. The latter has been widely used for data mining tasks and it owns the property of adaptability required by data stream clustering algorithms. Our method, called AIS-Clus, is able to detect novel concepts using the performance of the learning process of the AIS meta-heuristic. Furthermore, AIS-Clus has the ability to adapt its model to handle concept drift and feature evolution for textual data streams. Experimental results have been performed on textual datasets where efficient and promising results are obtained.
Microtasking Software Failure Resolution
Authors: Adriano Christian
Published: April 2019

Open source software development enabled distributed teams of programmers to contribute to large software systems that became standards in the operation of government and business. Crowdsourcing went further by enabling contributions in the form of small and independent tasks. This allowed teams to scale from dozens to hundreds of people. While crowdsourcing established as industry practice in the areas of software testing, it is challenging for source code related tasks, e.g., software debugging. One of the reasons is that the complex dependencies in the source code can make many tasks difficult to partition and sequence, and later aggregate their outcomes. I am investigating these problems in the context of failure resolution tasks. A failure resolution task consists of inspecting the source code with the objective to identify and explain the root-cause of a software failure. My approach partitions code inspection into questions that are automatically instantiated from templates. I present here my research plan and the early results of experiments on the efficacy, efficiency, and scalability of my approach.

Generic Programming enables program constructs to be reused in a variety of situations. In programming languages, idea of generic programming is being opted through a variety of generic mechanisms. Generic mechanisms are either directly applied to pre-existing language constructs or it provides its own components for generic implementation. In this paper, we present such generic mechanisms in an organized way such that it appears as "one mechanism intensify other". Our aim is to exhibit generic evolution among mainstream object oriented programming languages (OOPLs). Hence, we analyze such approaches for better expressiveness and type-safety of generic programming as they evolved in OOPLs. This brief review article will help developers and researchers to precisely understand the generic mechanism in mainstream OOPLs.
Envisioning an Intelligent Collaborative Integrated Development Environment
Authors: Roy Subhajit
Published: April 2019

Abstract Programming editors have evolved over the years. However, we still lack an environment that can allow on-the-fly collaboration between multiple programmers. We envision Incide, an integrated development environment that allows a synergistic collaboration environment by using program synthesis technology to combine partial solutions from multiple programmers attempting to solve the (same) problem into one concrete solution. This solution is then communicated to the editor of each programmer as patches along with personalization on syntactic elements like choice of programming language constructs and variable names. We believe that such editors will improve productivity on complex solutions by bringing a discipline into combining the intuition and intellect of multiple programmers.

Recent years have witnessed a growing interest in urban air pollution monitoring, where hundreds of low-cost air quality sensors are deployed city-wide. To guarantee data accuracy and consistency, these sensors need periodic calibration after deployment. Since access to ground truth references is often limited in large-scale deployments, it is difficult to conduct city-wide post-deployment sensor calibration. In this work we propose In-field Calibration Transfer (ICT), a calibration scheme that transfers the calibration parameters of source sensors (with access to references) to target sensors (without access to references). On observing that (i) the distributions of ground truth in both source and target locations are similar and (ii) the transformation is approximately linear, ICT derives the transformation based on the similarity of distributions with a novel optimization formulation. The performance of ICT is further improved by exploiting spatial prediction of air quality levels and multi-source fusion. Experiments show that ICT is able to calibrate the target sensors as if they had direct access to the references.
Using Built-In Sensors to Predict and Utilize User Satisfaction for CPU Settings on Smartphones
Authors: Poyraz Emirhan , Memik Gokhan
Published: April 2019

Understanding user experience/satisfaction with mobile systems in order to manage computational resources has become a popular approach in recent years. One of the key issues in this area is to gauge user satisfaction. In this paper, we propose and evaluate a system to save energy by altering CPU core count and frequency while keeping users satisfied. Specifically, the system uses the sensor data collected from two popular personal devices: a smartphone and a smartwatch. In the proposed architecture, we first develop prediction models by collecting sensor data along with user performance satisfaction inputs. Then, our system predicts users' current satisfaction and sets CPU core/frequency based on these predictions in real-time. We observe that sensor data gathered from these two devices are highly correlated with users' instantaneous satisfaction of the phone.

We evaluate the proposed system by developing and comparing two different models. First, we develop a user-independent (user-oblivious) model by using data gathered from 10 users. Second, we develop user-dependent (personal) models for 20 different users. We demonstrate that both models can predict satisfaction with over 97% accuracy on average when a binary satisfaction model is used (i.e., users indicating satisfied versus unsatisfied). The prediction accuracy is over 91% on average if a 3-level satisfaction model is used. Our results also show that when compared to default scheme, the user-independent and user-dependent models save 8.96% and 10.12% of the total system energy on average, respectively, without impacting user satisfaction.
Polarization and Fake News

Published: April 2019

Users’ polarization and confirmation bias play a key role in misinformation spreading on online social media. Our aim is to use this information to determine in advance potential targets for hoaxes and fake news. In this article, we introduce a framework for promptly identifying polarizing content on social media and, thus, “predicting” future fake news topics. We validate the performances of the proposed methodology on a massive Italian Facebook dataset, showing that we are able to identify topics that are susceptible to misinformation with 77% accuracy. Moreover, such information may be embedded as a new feature in an additional classifier able to recognize fake news with 91% accuracy. The novelty of our approach consists in taking into account a series of characteristics related to users’ behavior on online social media such as Facebook, making a first, important step towards the mitigation of misinformation phenomena by supporting the identification of potential misinformation targets and thus the design of tailored counter-narratives.

Published: April 2019

Chromatographic separation has been widely applied in various fields, such as chemical engineering, precision medicine, energy, and biology. Because chromatographic separation is based on differential partitioning between the mobile phase and stationary phase and affected by band dispersion and mass transfer resistance from these two phases, the materials used as the stationary phase play a decisive role in separation performance. In this review, we discuss the design of separation materials to achieve the separation with high efficiency and high resolution and highlight the well-defined materials with uniform pore structure and unique properties. The achievements, recent developments, challenges, and future trends of such materials are discussed. Furthermore, the surface functionalization of separation ma-terials for further improvement of separation performance is reviewed. Finally, future research directions and the challenges of chromatographic separation are presented.

Aim. To analyze the radiological, clinical, and prognostic features of primary pulmonary salivary gland-type tumors (SGTs) and improve their diagnosis. Materials and Methods. We retrospectively collected clinical and pathological data for 32 SGT cases confirmed by pathology and analyzed their radiological features, clinical presentations, and treatment outcomes. Results. Mucoepidermoid carcinoma (MEC) was more likely to occur in younger patients than was adenoid cystic carcinoma (ACC) (35 ± 15 years vs 48 ± 16 years, p=0.038). MEC was equally distributed between both sexes, whereas ACC was more frequent in females (66.7%). The main presenting symptom of SGT was cough (56.3%), followed by dyspnea (40.6%), associated with the tumor location. ACC more frequently involved the trachea or main bronchus (86.7% vs 25.0%, p=0.001) and more commonly presented as lobulated or circumferential thickening than MEC (93.3% vs 37.5%, p=0.002). MEC more frequently presented as obvious enhancement than ACC (68.8% vs 31.3%, p=0.001). CT findings suggestive of airway obstructive disease were more likely to be observed with MEC than ACC (73.3% vs 25.0%; p=0.021). The SUVmax in 8 of 10 patients with PET/CT data exceeded 2.2 but was less than 6.0. The overall survival (OS) at 3 and 5 years was 90.9% and 72.2% in all patients, respectively. Tumor-node-metastasis (TNM) stage, surgery, and patient age were associated with OS (p≤0.001, p=0.001, and p=0.001, respectively). Conclusion. SGTs commonly occur in patients at a young age and are associated with weak invasive features and a good prognosis. The predominant site and CT characteristics are significantly different between ACC and MEC.
A Multicomponent Particle Model and Linear Fitting Calibration Method for Heterogeneous Rocks

Published: April 2019

Deformation and failure of rock are very important to underground space engineering. In this paper, a new three‐dimensional multicomponent bonded‐particle model is developed for heterogeneous rocks. Granite samples from the Sanshandao Gold Mine are first analyzed using a microscope. Cylindrical and disc models consisting of four minerals (i.e., plagioclase, potash feldspar, quartz, and biotite) are built to simulate the behavior of the granite under compressive and tensile tests. To improve the calibration efficiency, a new method for determining the microparameters of minerals is proposed. Uniaxial compression, triaxial compression, and Brazilian tests are carried out in the lab. The failure pattern and stress‐strain curves are obtained from numerical simulations and verified with those observed in the experiments. Furthermore, the Mohr–Coulomb and Hoek–Brown strength parameters are obtained and compared with the experimental results. The multicomponent particle model is shown to well reproduce the behavior of granite under the compressive and tensile tests. The multicomponent bonded‐particle model significantly improves the accuracy of three parameters: the ratio of tensile strength to uniaxial compressive strength, the friction angle, and the parameter mi of the Hoek–Brown criterion. The linear fitting calibration method provides a fast and efficient way to determine the microparameters of particles in heterogeneous rocks.
