Combining Multiple Features for Image Popularity Prediction in Social Media

Popularity prediction, aiming at predicting target items' total interactions with users, is a very significant type of problem and has attracted a lot of attention in recent years. It can benefit a lot of real applications, such as cold-start recommendation[8] and online advertising [4]. The Social Media Prediction Task-1 (SMP-T1) of the ACM Multimedia 2017 Grand Challenge is designed to predict popularity of photos published by users in social media. In this paper, we introduce the method adopted in this contest detailedly. It is mainly based on carefully designed features and selected regression models. We demonstrate the effectiveness of each feature proposed for this task via univariate and ablation tests by employing different models. Based on those results, we further integrate the verified useful features with the best-performing regression model to obtain final prediction results. We participated this contest with the team name "heihei" and ranked in the second place in the final ranking list.
Characterization of the acoustic signature of a small remotely operated vehicle for detection

We present a characterization of both the hydrodynamic flow associated with the motion of a small remotely operated vehicle (ROV) and the acoustic signature emitted from the ROV. We experimentally measure the acoustic signature of a commercial off-the-shelf mini ROV by recording the underwater sound with stationary hydrophones, simultaneously compared with measuring the flow fields with particle image velocimetry (PIV). By conducting the trials during a variety of ROV maneuvers, we quantify the most underlying mechanisms that generate the ROV acoustic signatures which include the electric motor signal, propeller induced signal, pressure fluctuation due to the propeller wash and emission induced by flow over the ROV body. From the experimental results, we conclude that the electric motor is the main source of acoustic signature. The dominant acoustic frequency is between 70 Hz to 80 Hz with sound pressure level of 146 dB re 1 μPa at 1 m. Based on this characterization, we predict the feasibility of the detection of a small ROV using a model for transmission loss to predict the influences of attenuation and spreading. The predictions of detecting performance are based on a signal-to-noise ratio (SNR) for typical environments: shallow coastal water, ports and harbors, and deep oceans. Based on these models, we can quantify potentially the effective range of passive detection of underwater vehicle in the three distractive environments.
Three‐dimensional cohesive modeling of dynamic mixed‐mode fracture

A cohesive formulation of fracture is taken as a basis for the simulation of processes of combined tension‐shear damage and mixed‐mode fracture in specimens subjected to dynamic loading. Our three‐dimensional finite‐element calculations account explicitly for crack nucleation, microcracking, the development of macroscopic cracks and inertia. In particular, a tension‐shear damage coupling arises as a direct consequence of slanted microcrack formation in the process zone. We validate the model against the three‐point‐bend concrete beam experiments of Guo et al. (International Journal of Solids and Structures 1995; 32(17/18):2951–2607), John (PhD Thesis, Northwestern University, 1988), and John and Shah (Journal of Structural Engineering 1990; 116(3):585–602) in which a pre‐crack is shifted from the central cross‐section, leading to asymmetric loading conditions and the development of a mixed‐mode process zone. The model accurately captures the experimentally observed fracture patterns and displacement fields, as well as crack paths and crack‐tip velocities, as a function of pre‐crack geometry and loading conditions. In particular, it correctly accounts for the competition between crack‐growth and nucleation mechanisms. Copyright © 2001 John Wiley & Sons, Ltd.
Reducing the environmental impact of taxi operation: The taxi-sharing use case

Considering the fast development of urban areas and the increasing environmental awareness, we focus in this paper on a taxi-sharing system for improving the efficiency of public transport. In particular, we present a realistic and large-scale evaluation of the environmental impact of this system. The proposed method improves the efficiency of this form of public transport by determining, on the fly, the best match between taxi user requests, which leads to a reduction of the total and vacant travel distance. Our results show important reductions of CO2 emissions with full deployment of the system, reaching 9% under a higher demand scenario.
The use of psychotropics and survival in demented elderly individuals

The present study aimed to examine the use of psychotropics and its relation to survival in demented elderly persons. A random sample of 700 individuals, aged 75 years or older, was drawn from the population of Kuopio city in January 1998. A geriatrician and a nurse carried out clinical examinations of 601 individuals, of whom 137 suffered from dementia according to DSM-IV criteria. The lifespan was calculated from the date of examination in 1998 to the end of 2003. In survival analyses, subjects were divided according to psychotropic use into groups: (i) users of only one of kind of psychotropics and (ii) concomitant users of all kinds of psychotropics. Psychotropics were classified into antipsychotics, antidepressants and a group of anxiolytics and hypnotics/sedatives. Seventy-one percent (n=97) of demented elderly individuals used a psychotropic drug. Age- and sex-adjusted survival did not differ by severity of dementia (P=0.076) or by the diagnosis of dementia (P=0.54). When survival was compared with nonusers of psychotropics, the hazard ratio was 2.75 (P=0.002) for individuals who used antipsychotics as their only psychotropic medicine and 1.76 (95% confidence interval 1.09–2.86) for concomitant users of all kinds of psychotropics. The use of several psychotropics or antipsychotics is a risk factor for death in demented elderly persons.
The Validity and Reliability of the German Version of the Somatoform Dissociation Questionnaire (SDQ-20)

The present study investigated the validity of the German version of the Somatoform Dissociation Questionnaire (SDQ-20), a scale designed to measure somatoform dissociative symptoms. Somatoform dissociation involves physical manifestations of a dissociation of the personality and is considered a unique entity in the phenomenological spectrum of dissociation. The validity and reliability of the German version of the SDQ-20 was examined using a sample of 225 patients with (n = 39) and without dissociative disorders who were recruited from several in- and outpatient psychiatric clinics. Patients were assessed using structured diagnostic interviews; diagnostic checklists; and self-rating scales for dissociation, and posttraumatic stress. Patients with dissociative disorders reported significantly more (p < .001) somatoform dissociative symptoms than patients without dissociative disorders (criterion validity). Significant correlations (p < .001) were found between scores of somatoform dissociation, psychoform dissociation, posttraumatic stress symptoms, and traumatic childhood experiences (construct validity). Reliability was corroborated by a Cronbach's alpha coefficient of . 91 and a test–retest correlation of . 89. A component factor analysis suggested unidimensionality of the SDQ-20. In conclusion, the psychometric properties and cross-cultural validity of the German version of the SDQ-20 are excellent. Our results form the basis for the further study of somatoform dissociation in German-speaking populations.
Decreased DGCR 8 Expression and miRNA Dysregulation in Individuals with 22 q 11 . 2 Deletion Syndrome

Deletion of the 1.5–3 Mb region of chromosome 22 at locus 11.2 gives rise to the chromosome 22q11.2 deletion syndrome (22q11DS), also known as DiGeorge and Velocardiofacial Syndromes. It is the most common micro-deletion disorder in humans and one of the most common multiple malformation syndromes. The syndrome is characterized by a broad phenotype, whose characterization has expanded considerably within the last decade and includes many associated findings such as craniofacial anomalies (40%), conotruncal defects of the heart (CHD; 70–80%), hypocalcemia (20–60%), and a range of neurocognitive anomalies with high risk of schizophrenia, all with a broad phenotypic variability. These phenotypic features are believed to be the result of a change in the copy number or dosage of the genes located in the deleted region. Despite this relatively clear genetic etiology, very little is known about which genes modulate phenotypic variations in humans or if they are due to combinatorial effects of reduced dosage of multiple genes acting in concert. Here, we report on decreased expression levels of genes within the deletion region of chromosome 22, including DGCR8, in peripheral leukocytes derived from individuals with 22q11DS compared to healthy controls. Furthermore, we found dysregulated miRNA expression in individuals with 22q11DS, including miR-150, miR-194 and miR-185. We postulate this to be related to DGCR8 haploinsufficiency as DGCR8 regulates miRNA biogenesis. Importantly we demonstrate that the level of some miRNAs correlates with brain measures, CHD and thyroid abnormalities, suggesting that the dysregulated miRNAs may contribute to these phenotypes and/or represent relevant blood biomarkers of the disease in individuals with 22q11DS.

Interaction of CK1δ with γTuSC ensures proper microtubule assembly and spindle positioning

Casein kinase 1δ (CK1δ) family members associate with microtubule-organizing centers from yeast to humans. Budding yeast CK1δ, Hrr25, directly phosphorylated γTuSC proteins in vivo and in vitro, and this phosphorylation promoted δTuSC integrity and activity in biochemical assays.
IoTGuard: Dynamic Enforcement of Security and Safety Policy in Commodity IoT

—Broadly deﬁned as the Internet of Things (IoT), the growth of commodity devices that integrate physical processes with digital connectivity has changed the way we live, play, and work. To date, the traditional approach to securing IoT has treated devices individually. However, in practice, it has been recently shown that the interactions among devices are often the real cause of safety and security violations. In this paper, we present I O TG UARD , a dynamic, policy-based enforcement system for IoT, which protects users from unsafe and insecure device states by monitoring the behavior of IoT and trigger-action platform apps. I O TG UARD operates in three phases: (a) implementation of a code instrumentor that adds extra logic to an app’s source code to collect app’s information at runtime, (b) storing the apps’ information in a dynamic model that represents the runtime execution behavior of apps, and (c) identifying IoT safety and security policies, and enforcing relevant policies on the dynamic model of individual apps or sets of interacting apps. We demonstrate I O TG UARD on 20 ﬂawed apps and ﬁnd that I O TG UARD correctly enforces 12 of the 12 policy violations. In addition, we evaluate I O TG UARD on 35 SmartThings IoT and 30 IFTTT trigger-action platform market apps executed in a simulated smart home. I O TG UARD enforces 11 unique policies and blocks 16 states in six (17.1%) SmartThings and ﬁve (16.6%) IFTTT apps. I O TG UARD imposes only 17.3% runtime overhead on an app and 19.8% for ﬁve interacting apps. Through this effort, we introduce a rigorously grounded system for enforcing correct operation of IoT devices through systematically identiﬁed IoT policies, demonstrating the effectiveness and value of monitoring IoT apps with tools such as I O TG UARD .
Factors influencing the adoption of cloud computing in SME: A systematic review

The main purpose of this paper is to review the literatures on the adoption of Cloud Computing by SMEs in order to learn the current state of Cloud Computing studies and identify gaps for future research. Twenty-two articles were reviewed and analyzed from various journals and conference proceedings that were published on Cloud Computing adoption, acceptance, and diffusion. Findings revealed that there are growing numbers of studies in the adoption of Cloud Computing from different perspectives, yet there is a lack of theoretical and empirical studies in the field. Findings also indicated that there are only few articles evaluated the organizational perspective of Cloud Computing adoption in SMEs, while the majority of studies discussed operational and technical issues. Furthermore, this review observed various factors influencing the adoption of Cloud computing, which were addressed based on the four main criteria of the acceptance and diffusion of technological innovations, which are individual, organization, technology and environment.
Measuring Neuronal Branching Patterns Using Model-Based Approach

Neurons have complex branching systems which allow them to communicate with thousands of other neurons. Thus understanding neuronal geometry is clearly important for determining connectivity within the network and how this shapes neuronal function. One of the difficulties in uncovering relationships between neuronal shape and its function is the problem of quantifying complex neuronal geometry. Even by using multiple measures such as: dendritic length, distribution of segments, direction of branches, etc, a description of three dimensional neuronal embedding remains incomplete. To help alleviate this problem, here we propose a new measure, a shape diffusiveness index (SDI), to quantify spatial relations between branches at the local and global scale. It was shown that growth of neuronal trees can be modeled by using diffusion limited aggregation (DLA) process. By measuring “how easy” it is to reproduce the analyzed shape by using the DLA algorithm it can be measured how “diffusive” is that shape. Intuitively, “diffusiveness” measures how tree-like is a given shape. For example shapes like an oak tree will have high values of SDI. This measure is capturing an important feature of dendritic tree geometry, which is difficult to assess with other measures. This approach also presents a paradigm shift from well-defined deterministic measures to model-based measures, which estimate how well a model with specific properties can account for features of analyzed shape.
Acute effect of environmental temperature during exercise on subsequent energy intake in active men.

BACKGROUND The performance of exercise while immersed in cold water has been shown to influence energy intake in the subsequent meal. However, the effect of ambient temperature during land-based exercise is not known. OBJECTIVES Our aims were to investigate the effect of exercise performed in the heat on energy intake in the subsequent meal and to determine concentrations of circulating appetite-related hormones. DESIGN In a randomized, counterbalanced design, 11 active male participants completed 3 experimental trials in a fasted state: exercise in the heat (36 degrees C), exercise in a neutral temperature (25 degrees C), and a resting control (25 degrees C). The exercise trials consisted of treadmill running for 40 min at 70% VO(2peak). After each trial, participants were presented with a buffet-type breakfast of precisely known quantity and nutrient composition, which they could consume ad libitum. RESULTS Energy intake was greater after exercise in the neutral temperature compared with the control (P = 0.021) but was similar between exercise in the heat and the control and between the 2 exercise trials. When accounting for the excess energy expended during exercise, relative energy intake during exercise in the heat was lower than the control (P = 0.002) but was similar between exercise in the neutral temperature and the control and between exercise in the heat and in the neutral temperature. The lower relative energy intake after exercise in the heat was associated with an elevated tympanic temperature and circulating concentrations of peptide YY (P < 0.05). CONCLUSION Exercise in a neutral environmental temperature is associated with higher energy intake in the subsequent meal compared with a control, whereas exercise in the heat is not.
Epidemiology, Prognosis, and Evolution of Management of Septic Shock in a French Intensive Care Unit: A Five Years Survey

Purpose. To evaluate the epidemiology, prognosis, and management of septic shock patients hospitalized in our intensive care unit (ICU). Materiel and Methods. Five-year monocenter observational study including 320 patients. Results. ICU mortality was 54.4%. Independent mortality risk factors were mechanical ventilation (OR = 4.97), Simplify Acute Physiology Score (SAPS) II > 60 (OR = 4.28), chronic alcoholism (OR = 3.38), age >65 years (OR = 2.65), prothrombin ratio <40% (OR = 2.37), and PaO2/FiO2 ratio <150 (OR = 1.91). These six mortality risk factors recovered allow screening immediately septic shock patients with a high mortality risk. Morbidity improved with time (diminution of septic shock complications, increase of the number of days alive free from mechanical ventilation and vasopressors on day 28), concomitant to an evolution of the management (earlier institution of all replacement and medical therapies and more initial volume expansion). There was no difference in mortality. Conclusion. Our study confirms a high mortality rate in septic shock patients despite a new approach of treatment.
Role of ATP-Binding-Cassette Transporter Genes in High-Frequency Acquisition of Resistance to Azole Antifungals in Candida glabrata

ABSTRACT Candida glabrata has been often isolated from AIDS patients with oropharyngeal candidiasis treated with azole antifungal agents, especially fluconazole. We recently showed that the ATP-binding-cassette (ABC) transporter gene CgCDR1 was upregulated in C. glabrata clinical isolates resistant to azole antifungal agents (D. Sanglard, F. Ischer, D. Calabrese, P. A. Majcherczyk, and J. Bille, Antimicrob. Agents Chemother. 43:2753–2765, 1999). Deletion of CgCDR1 in C. glabrata rendered the null mutant hypersusceptible to azole derivatives and showed the importance of this gene in mediating azole resistance. We observed that wild-type C. glabrata exposed to fluconazole in a medium containing the drug at 50 μg/ml developed resistance to this agent and other azoles at a surprisingly high frequency (2 × 10−4 to 4 × 10−4). We show here that this high-frequency azole resistance (HFAR) acquired in vitro was due, at least in part, to the upregulation ofCgCDR1. The CgCDR1 deletion mutant DSY1041 could still develop HFAR but in a medium containing fluconazole at 5 μg/ml. In the HFAR strain derived from DSY1041, a distinct ABC transporter gene similar to CgCDR1, calledCgCDR2, was upregulated. This gene was slightly expressed in clinical isolates but was upregulated in strains with the HFAR phenotype. Deletion of both CgCDR1 and CgCDR2suppressed the development of HFAR in a medium containing fluconazole at 5 μg/ml, showing that both genes are important mediators of resistance to azole derivatives in C. glabrata. We also show here that the HFAR phenomenon was linked to the loss of mitochondria in C. glabrata. Mitochondrial loss could be obtained by treatment with ethidium bromide and resulted in acquisition of resistance to azole derivatives without previous exposure to these agents. Azole resistance obtained in vitro by HFAR or by agents stimulating mitochondrial loss was at least linked to the upregulation of both CgCDR1 and CgCDR2.
Triangulation of Graphs { Algorithms Giving Small Total State Space Triangulation of Graphs { Algorithms Giving Small Total State Space

The problem of achieving small total state space for triangulated belief graphs (networks) is considered. It is an NP-complete problem to nd a triangulation with minimum state space. Our interest in this topic originates from the eld of knowledge engineering where the applied knowledge representation scheme is provided by the notion of causal probabilistic networks (belief networks); CPNs for short. The application of a generalised evidence propagation scheme in CPNs requires triangularity (chordality) of the actual network. The paper includes a survey and evaluation of existing triangulation algorithms most of which are found to be highly ineeective w.r. t. the applied ee-ciency measure. Simple heuristic methods are presented and found to produce high-quality triangulations. Moreover, we introduce a method by which any non-minimal triangulation may be turned into a minimal one. Furthermore, we present a stochastic algorithm based on a technique known as simulated annealing by which the optimal solution to NP-complete problems may be found with probability arbitrarily close to 1.
Phyto-anxiolytic effects of a fixed herbal drug combination for the relief of stress and its potential to reduce benzodiazepine use

Stress affects already young healthy people and many elderly or patients with psychiatric disorders receive benzodiazepines. A recent study has shown that the phyto-anxiolytic herbal extract combination Ze 185 (Relaxane®) significantly reduced the subjective stress reaction in healthy men in an acute stress setting. Further, in a retrospective data analysis from stationary patients in a psychiatric hospital in Switzerland it was concluded that the use of benzodiazepines could be reduced under the treatment with Ze 185. As an example in evidence-based phytotherapy Ze 185 is discussed in the context of stress and anxiety-related disorders.
The influence of image objective parameters on the probability of finding corresponding points

This paper deals with the influence of global and local objective image parameters of the analyzed image on the process of finding corresponding points. We examined the impact of objective parameters on the usability of some significant point detectors. Moreover, the paper also contains the comparison of the reliability of finding corresponding points for a particular image point by using common methods and our new proposed method in dependency on some image objective parameters. The executed test confirms the advantage of the designed method. Specific improvement of the original method for finding corresponding points was proposed and described in this paper too.
