Emotion Differentiation based on Decision-Making in Emotion Model

Having emotions is essential for robots in order for them to understand and sympathize with people's feelings. In addition, it may allow robots to be accepted in human society. The role of emotions in decision-making is another important perspective. In this paper, a model of emotions is proposed based on various neurological and psychological findings related to empathic communication between humans and robots. Subsequently, a decision-making mechanism based on affects using convolutional long short-term memory and deep deterministic policy gradient is examined. We set a “facial expression” task simulating mother-child interactions and verified emotion differentiation during the task.
Parenting Styles and Parent–Adolescent Relationships: The Mediating Roles of Behavioral Autonomy and Parental Authority

The parent–adolescent relationship has been a classic research topic, and researchers have found that parenting styles (e.g., authoritative, authoritarian) are closely related to various qualities of parent-adolescent relationships (e.g., cohesion, conflict). However, little empirical work has addressed how these variables correlate with each other in mainland China, nor has prior research addressed internal psychological mechanisms. The present study investigated the associations between parenting styles and parent–adolescent relationship factors, examined the mediating effects of adolescents’ expectations of behavioral autonomy and beliefs about parental authority, and explored whether adolescent gender moderated these effects. Results from a sample of 633 Chinese adolescents (7th grade: Mage = 13.50 ± 0.62 years, 9th grade: Mage = 15.45 ± 0.67 years, 11th grade: Mage = 17.30 ± 0.75 years) suggested similar levels of parent–adolescent conflict frequency for all parenting styles. However, for parent–adolescent conflict intensity, youth of neglectful and authoritarian parents reported higher levels compared to those with indulgent parents. The highest levels of cohesion with both parents were reported by adolescents with authoritative parents, followed by indulgent, authoritarian and neglect parenting styles. Cohesion with mothers for youth with authoritative or indulgent mothers was higher for girls than boys. Adolescents’ expectation for behavioral autonomy mediated the links between parenting style and conflict, whereas adolescents’ beliefs about the legitimacy of parental authority mediated the links between parenting style and cohesion; some of these mediating effects differed by gender. Findings highlight the importance of studying potential effects of adolescents’ values and attitudes within the family system in specific cultural contexts.
Analysis of Determinant Factors of User Acceptance of Mobile Payment System in Indonesia (A Case Study of Go-Pay Mobile Payment)

Mobile payment in Indonesia is designed to help the growth of online transport, such as GO-J ek with mobile payment products, which is the GO-Pay mobile payment to make it easier for customers to pay drivers and merchants. The study was carried out for the analysis and evaluation of the acceptance of technology in the mobile payment GO-Pay using the technology acceptance model (TAM). The research was carried out using the quantitative research approach by obtaining 284 active respondents using the GO-Pay mobile payment. The research question in this research is whether GO-Pay as a mobile payment system can be accepted in Indonesia? The result of this research is factor of perceived about usefulness, ease of use, mobility, and the attitude factor can make GO-Pay as mobile payment is acceptable in Indonesia. For the perceived trust, it is not a significant effect, but the effect on perceived trust is perceived reputation, while for the environmental risk it does not affect the perceived reputation.
Densely Connected Attention Propagation for Reading Comprehension

We propose DecaProp (Densely Connected Attention Propagation), a new densely connected neural architecture for reading comprehension (RC). There are two distinct characteristics of our model. Firstly, our model densely connects all pairwise layers of the network, modeling relationships between passage and query across all hierarchical levels. Secondly, the dense connectors in our network are learned via attention instead of standard residual skip-connectors. To this end, we propose novel Bidirectional Attention Connectors (BAC) for efficiently forging connections throughout the network. We conduct extensive experiments on four challenging RC benchmarks. Our proposed approach achieves state-of-the-art results on all four, outperforming existing baselines by up to 2.6% to 14.2% in absolute F1 score.
Cognitive and Brain Activity Changes After Mnemonic Strategy Training in Amnestic Mild Cognitive Impairment: Evidence From a Randomized Controlled Trial

Background: Mnemonic strategy training (MST) has been shown to improve cognitive performance in amnestic mild cognitive impairment (a-MCI), however, several questions remain unresolved. The goal of the present study was to replicate earlier pilot study findings using a randomized controlled design and to evaluate transfer effects and changes in brain activation. Methods: Thirty patients with a-MCI were randomized into MST or education program. At baseline, participants completed clinical and neuropsychological assessments as well as structural and functional magnetic resonance imaging (fMRI). Interventions were administered individually and comprised four sessions, over 2 weeks. MST taught patients to use a three-step process to learn and recall face-name associations. Post-treatment assessment included fMRI, a separate face-name association task, neuropsychological tests, and measures of metamemory. Behavioral (i.e., non-fMRI) measures were repeated after one and 3-months. Results: Participants in the MST condition showed greater improvement on measures of face-name memory, and increased associative strategy use; effects that were accompanied by increased fMRI activation in the left anterior temporal lobe. While all participants reported greater contentment with their everyday memory following intervention, only the MST group reported significant improvements in their memory abilities. There was no clear indication of far-transfer effects to other neuropsychological tests. Conclusion: Results demonstrate that patients with a-MCI not only show stimulus specific benefits of MST, but that they appear capable of transferring training to at least some other cognitive tasks. MST also facilitated the use of brain regions that are involved in face processing, episodic and semantic memory, and social cognition, which are consonant with the cognitive processes engaged by training.
A Flattened Metadata Service for Distributed File Systems

Key-Value stores provide scalable metadata service for distributed file systems. However, the metadata's organization itself, which is organized using a directory tree structure, does not fit the key-value access pattern, thereby limiting the performance. To address this issues, we propose a distributed file system with a flattened and fine-grained division metadata service, LocoMeta, to bridge the performance gap between file system metadata and key-value stores. LocoMeta is designed to bridge the gap between file metadata to key-value store with two techniques. First, LocoMeta flattens the directory content and structure, which organizes file and directory index nodes in a flat space while reversely indexing the directory entries. Second, it exploits a fine-grained division method to improve the key-value access performance. Evaluations show that LocoMeta with eight nodes boosts the metadata throughput by five times, which approaches 93 percent throughput of a single-node key-value store, compared to 18 percent in the state-of-the-art IndexFS.
Monitoring the Process of Endostar-Induced Tumor Vascular Normalization by Non-contrast Intravoxel Incoherent Motion Diffusion-Weighted MRI

Tumor vascular normalization has been proposed as a new concept in anti-tumor angiogenesis, and the normalization window is considered as an opportunity to increase the effect of chemoradiotherapy. However, there is still a lack of a non-invasive method for monitoring the process of tumor vascular normalization. Intravoxel incoherent motion diffusion-weighted magnetic resonance imaging (IVIM DW-MRI) is an emerging approach which can effectively assess microperfusion in tumors, without the need for exogenous contrast agents. However, its role in monitoring tumor vascular normalization still needs further study. In this study, we established a tumor vascular normalization model of CT26 colon-carcinoma-bearing mice by means of Endostar treatment. We then employed IVIM DW-MRI and immunofluorescence to detect the process of tumor vascular normalization at different times after treatment. We found that the D* values of the Endostar group were significantly higher than those of the control group on days 4, 6, 8, and 10 after treatment, and the f values of the Endostar group were significantly higher than those of the control group on days 6 and 8. Furthermore, we confirmed through analysis of histologic parameters that Endostar treatment induced the CT26 tumor vascular normalization window starting from day 4 after treatment, and this window lasted for 6 days. Moreover, we found that D* and f values were well correlated with pericyte coverage (r = 0.469 and 0.504, respectively; P < 0.001, both) and relative perfusion (r = 0.424 and 0.457, respectively; P < 0.001, both). Taken together, our findings suggest that IVIM DW-MRI has the potential to serve as a non-invasive approach for monitoring Endostar-induced tumor vascular normalization.
Micro-Resonator Based Bivariate Detection of Glucose Concentration With Phenylboronic Acid Functionalized Reduced Graphene Oxide

We developed a biosensor based on radio frequency micro-resonator for sensitive detection of aqueous glucose solutions. The device incorporates a modified interdigital capacitor-based multilayer resonator realized using integrated passive device technology. In addition, reduced graphene oxide was functionalized by phenylboronic acid aided with graphene oxide for the selective binding of glucose molecules under an electromagnetic field, resulting in a reliable concentration-specific resonance characteristic of the samples. The resonance frequency and bivariate (in terms of magnitude dip and phase reversal of the reflection coefficient) characteristics were found to be linearly related to the glucose concentration, thereby demonstrating the utility of the proposed microwave passive sensor in the detection of glucose with a sensitivity of 0.32 MHz per dL−1. Furthermore, the corresponding variation in the capacitance and the impedance was accessed for each concentration of the glucose solutions.
Experimental Evaluation of Cooperativeness and Collision Safety of a Wearable Robot Arm

This paper presents an experimental evaluation of a collaborative task for a design assessment of a wearable robot arm. Wearable robotic devices have been recently proposed as a new concept of the human robot collaboration. In particular, wearable robot arms have been expected to complement our physical capabilities and perform multiple tasks simultaneously. However, a design principle of a wearable robot arm based on the cooperativeness and collision safety has not been discussed sufficiently. The design factors of the wearable robot arm are considered to have a dominant influence on the cooperativeness and collision safety. We therefore conducted an experiment to evaluate time required for a collaborative task and number of collisions with a robot arm device. Arm lengths and attachment positions were compared in the conducted experiment as a design factor of a wearable robot arm. The experimental results indicated a correlation between evaluation indexes and design factors. As a result, we suggest that the concept design of a wearable robot arm is recommended to consist of an extended arm length without constraints of the attachment positions.
Gesture Aided Speech for Deaf and Mute

Speech impaired people make use of sign language to communicate along with normal people. Common people also face difficulties to understand the gesture language. In order to minimize these real time issues, an attempt has been made to develop a system which consists of Flex sensors attached with the Data gloves along all fingers. These will be wearable gloves converts hand gestures into an audio output to interpret the expression. This reduces the communication gap that exists between mute and ordinary people. The proposed system plays corresponding recorded voice on an android phone connected to the hardware system via Bluetooth Module as an interpretation of the gesture. It is achieved by integrating flex sensor and 8051 microcontroller. The phone will use a text to speech converter to produce the output of corresponding gesture. This system offers high reliability and fast response as microcontroller works at a speed of 12 MHz. Processing time of microcontroller is much less than the time taken for a human to change from one gesture to another, the system works efficiently in real time scenario hence making the system faster.
Siena: Exploring the Design Space of Heterogeneous Memory Systems

Memory systems are crucial to the performance, power, and cost of high-performance computing systems. Recently, multiple factors are driving the need for more complex, deep memory hierarchies. However, architects and customers are struggling to design memory systems that effectively balance multiple, often competing, factors in this large, multidimensional, and fast-moving design space. In this paper, we systematically explore the organization of heterogeneous memory systems on a framework called Siena. Siena facilitates quick exploration of memory architectures with flexible configurations of memory systems and realistic memory workloads. We perform a design space exploration on 22 proposed memory systems using eight relevant workloads. Our results show that horizontal organizations of memories can achieve higher performance than vertical organizations when the distribution of memory traffic balances the performance gap between memories. However, the coupling effects through shared resources and application behaviors could negate the advantage of high-performance memory in horizontal organizations.
Herding and Social Media Word-of-Mouth: Evidence from Groupon

This study explores how herding, social media word-of-mouth (WOM), and their interaction effects drive product sales. While herding helps updating consumers’ beliefs about the product quality, social media WOM can also have an advertising effect. Using a panel data set consisting of about 500 deals from Groupon, we find both herding and Facebook-mediated WOM has a direct impact on sales, whereas Twitter-mediated WOM does not. More importantly, we theorize the interaction effect between herding and social media WOM and show they are complements in driving product sales. To uncover the underlying mechanisms, we find the herding effect is more salient for experience goods than for search goods, but the effect of Facebook-mediated WOM does not significantly differ between the two product categories. The comparison suggests that signaling product quality is the underlying mechanism of herding, while the effect of Facebook-mediated WOM is primarily through advertising, rather than signaling.
Pharmacokinetic and bioequivalence study of sugar-coated and film-coated eperisone tablets in healthy subjects: A randomized, open-label, three-way, reference-replicated crossover study .

OBJECTIVE Eperisone hydrochloride is used in the treatment of musculoskeletal disorders as a muscle relaxant via blocking of calcium channels. In this study, we aimed to investigate the within-subject variability (CVwR) of reference eperisone formulation for highly-variable drugs and to perform bioequivalence study of two oral formulations (sugar- and film-coated tablets) of eperisone hydrochloride 50 mg in healthy subjects by reference-replicated crossover study. MATERIALS AND METHODS 36 healthy Korean male subjects were recruited, and 33 subjects completed the study. A randomized, single-dose, open-label, three-way, three-sequence, reference formulation-replicated, crossover bioequivalence study was conducted to determine the bioequivalence of eperisone. Blood samples were collected before dosing and at 0.33, 0.67, 1, 1.5, 2, 2.5, 3, 4, 6, 8, and 12 hours after dosing. The plasma concentration of eperisone was determined using liquid chromatography-tandem mass spectrometry. RESULTS The CVwR of eperisone reference product was 33.17% for AUCt and 50.21% for Cmax. The acceptance limit for Cmax was scaled to 0.6984 - 1.4319 according to CVwR. The 90% confidence intervals for the test/reference geometric mean ratio were 0.8275 - 1.1692 for AUCt and 0.7587 - 1.1652 for Cmax, which were within the accepted bioequivalence limits. Single oral doses of eperisone hydrochloride 50 mg were generally well tolerated in healthy adult subjects in this study. CONCLUSION The newly developed film-coated tablet can be interchanged with the original sugar-coated tablet of eperisone. In addition, the reference scaling methods are more effective and economical than the classical method for assessing BE of HVDs.
Democratic Systems Increase Outgroup Tolerance Through Opinion Sharing and Voting: An International Perspective

Democracy may contribute to friendly attitudes and positive attitudes toward outgroups (i.e., outgroup tolerance) because members of democratic societies learn to exercise their rights (i.e., cast a vote) and, in the process, listen to different opinions. Study 1 was a survey study with representative samples from 33 countries (N = 45,070, 53.6% female) and it showed a positive association between the levels of democracy and outgroup tolerance after controlling for gender, age and the rate of immigrants influx from 2010 to 2013. Study 1 demonstrated that members in countries with higher political participation and civil liberty showed greater tolerance toward immigrants. In Study 2, we conducted an experimental study in Taiwan (N = 93, 67.7% female) to further examine two potential mediators (opinion sharing and voting) of the effect of democratic system on tolerance toward outgroups (i.e., attitudes toward mental patients) after controlling for gender and age. We found that when individuals were allowed to share opinions and vote, they had the highest positive other-oriented emotions toward mental patients, which in turn led to greater tolerance toward outgroups compared to those who were not allowed to share opinions or vote. In general, these results demonstrated that the democratic system plays a critical role in increasing outgroup tolerance. Limitations of the two studies and implications regarding opinion sharing, voting, democratic systems, and effects on outgroup tolerance are discussed.
Comparison of Unilateral With Bilateral Metal Stenting for Malignant Hilar Biliary Obstruction

Purpose: The main purpose of this study was to compare the clinical effectiveness between unilateral and bilateral metal stenting for malignant hilar biliary obstruction (MHBO). Methods: From January 2012 to October 2017, consecutive patients with MHBO underwent unilateral or bilateral stent insertion at our center. Technical and clinical success, stent patency, and survival were compared between these 2 groups. Results: A total of 110 patients with MHBO were included in this study. Technical successful rates of unilateral and bilateral stenting were 93.1% (54/58) and 90.4% (47/52), respectively (P=0.864). Clinical successful rates of unilateral and bilateral stenting were 96.4% (53/55) and 97.9% (46/47), respectively (P=1.000). There was no significant difference in stent patency period (unilateral, 182 d; bilateral, 198 d; P=0.999) and survival (unilateral, 189 d; bilateral, 199 d; P=0.867) between 2 groups. Conclusions: Unilateral and bilateral metal stenting had similar clinical effectiveness and long-term outcomes in patients with MHBO.
Sulfamethoxazole derivatives complexed with metals: a new alternative against biofilms of rapidly growing mycobacteria

Abstract Biofilms are considered important sources of infections on biomedical surfaces, and most infections involving biofilm formation are associated with medical device implants. Therefore, there is an urgent need for new antimicrobial compounds that can combat microbial resistance associated with biofilm formation. In this context, this work aimed to evaluate the antibiofilm action of sulfamethoxazole complexed with Au, Cd, Cu, Ni and Hg on rapidly growing mycobacteria (RGM), as well as to evaluate their safety through cytotoxic assays. The results demonstrate potentiation of the novel compounds in antibiofilm activity, mainly in the complex with Au, which was able to completely inhibit biofilm formation and had the capacity to destroy the biofilm at all the concentrations tested. All cytotoxic data suggest that the majority of sulfamethoxazole metallic derivatives are antimicrobial alternatives, as well as safe molecules, which could be used as potential therapeutic agents for bacterial and biofilm elimination.
A Theoretical Framework for Optimizing Multicarrier Systems Under Time and/or Frequency-Selective Channels

A highly relevant case of wireless transmission over time-selective channel (TSC) and/or frequency-selective channel (FSC) is when the channel-state information is only known at the receiver. Under these scenarios, this letter aims to derive the necessary conditions for a unitary transmitter matrix to maximize the coded modulation (CM) capacity. We approach the problem by considering the CM capacity upper bound (UB) instead of the general one due to simplification of the problem and tightness at high signal-to-noise ratio regions. The theoretical analysis reveals that the optimal waveforms spread the symbols over the domain of selectivity of the channel. To demonstrate this result, we evaluate orthogonal frequency-division multiplex- ing (OFDM), single carrier (SC), and orthogonal chirp-division multiplexing (OCDM), where we have that: 1) OCDM and SC are optimal for FSCs and 2) OCDM and OFDM are optimal for TSCs. Finally, we show that the UB has the same performance order as the real CM capacity, providing evidence that the UB criteria are meaningful for the optimization of a communication system.
