Cross matching of music and image

Human perception of music and image are highly correlated. Both of them can inspire human sensation like emotion and power. This paper investigates how to model the relationship between music and image using 47,888 music-image pairs extracted from music videos. We have two basic observations for this relationship: 1) music space exhibits simpler cluster structure than image space, and 2) the relationship between the two spaces is complex and nonlinear. Based on these observations, we develop Multiple Ranking Canonical Correlation Analysis (MR-CCA) to learn such relationship. MR-CCA clusters the music-image pairs according to their music parts, and then conducts Ranking CCA (R-CCA) for each cluster. Compared with classical CCA, R-CCA takes account of the pairwise ranking information available in our dataset. MR-CCA improves performance and significantly reduce computational cost. Experiment results show that R-CCA outperforms CCA, and MR-CCA has the best performance with a consistency score of 84.52% with human labeling. The proposed method can be generalized to model cross media relationship and has potential applications in video generation, background music recommendation, and joint retrieval of music and image.
Linking the evolution of gender variation to floral development.

BACKGROUND AND AIMS In the present review, I have endeavoured to conduct a joint assessment of the thinking underlying the evolutionary genetics of gender polymorphism and the developmental genetics of gender determination. It is my hope, through highlighting the historical development of ideas in two related but somewhat disparate sets of scientific literature, to encourage a synthetic perspective that integrates the two. SCOPE An overview is provided of various theories on the evolution of sex polymorphism and examples of evidence that has been brought to bear in support of them. Current knowledge on floral development is summarized, with an emphasis on gender variation. Finally, an attempt is made to integrate the two perspectives with the hope that it will encourage future research at the interface. CONCLUSIONS Evolutionary models of gender evolution have, of necessity, posited genetic effects that are relatively simple in their impacts. Emerging insights from developmental genetics have demonstrated that the underlying reality is a more complex matrix of interacting factors. The study of gender variation in plants is poised for significant advance through the integration of these two perspectives. Bringing genomic tools to bear on population-level processes, we may finally develop a comprehensive perspective on the evolution of floral gender.
The Relationship between Information Systems (IS) Assets, Organizational Capabilities, and IS-enabled Absorptive Capacity in U.S. State Information Technology Departments

Despite the recognition that information is a strategic asset for any state government, we lack research on the deployment and use of information systems in the U.S. state government context. Information systems are central for state agencies’ efforts to develop optimal responses to demands from their internal and external constituents. We examine how a specific IS asset combines with prior knowledge to influence organizational capabilities. We also examine the connection between organizational capabilities and the IS-enabled absorptive capacity of U.S. state IT departments from the perspective of IS employees. This study may help researchers and practitioners understand the role of IS assets in forming IS-enabled absorptive capacity in government organizations. We collected survey data from 417 government IS employees that represented 21 different states. The findings indicate that the role of an IS asset depends on the type of asset. Inside-out IS assets (ERP) moderate the relationship between prior knowledge and organizational capabilities, while outside-in IS assets (CRM) directly affect organizational capabilities. In addition, organizational capabilities can directly affect IS-enabled absorptive capacity in IT departments. This research increases our understanding of the influence of different IS assets on IS-enabled absorptive capacity in state government IT departments. We discuss limitations and directions for future research.
Particle cooling in Vaporizing Coolant

The approximate mathematical model for a cooling of the particle in a volatile liquid is developed and analyzed. Despite the precise model is complex and requires the solution of the nonstationary two-phase flow equations with the conjugated heat transfer boundary problem for the particle, vapor, and liquid cooling pool, the considered simple model may be of interest. Vapor is permanently produced and removed from the coolant pool. Analysis of the model obtained resulted in some correlations for the three main parameters of the cooling process, which may be used for estimation of the particle cooling.
Psychopathic traits influence amygdala–anterior cingulate cortex connectivity during facial emotion processing

Abstract There is accumulating evidence that youths with antisocial behavior or psychopathic traits show deficits in facial emotion recognition, but little is known about the neural mechanisms underlying these impairments. A number of neuroimaging studies have investigated brain activity during facial emotion processing in youths with Conduct Disorder (CD) and adults with psychopathy, but few of these studies tested for group differences in effective connectivity—i.e. changes in connectivity during emotion processing. Using functional magnetic resonance imaging and psycho-physiological interaction methods, we investigated the impact of CD and psychopathic traits on amygdala activity and effective connectivity in 46 male youths with CD and 25 typically-developing controls when processing emotional faces. All participants were aged 16–21 years. Relative to controls, youths with CD showed reduced amygdala activity when processing angry or sad faces relative to neutral faces, but the groups did not significantly differ in amygdala-related effective connectivity. In contrast, psychopathic traits were negatively correlated with amygdala–ventral anterior cingulate cortex connectivity for angry vs neutral faces, but were unrelated to amygdala responses to angry or sad faces. These findings suggest that CD and psychopathic traits have differential effects on amygdala activation and functional interactions between limbic regions during facial emotion processing.
Lessons from Amphioxus Bauplan About Origin of Cranial Nerves of Vertebrates That Innervates Extrinsic Eye Muscles

Amphioxus is the living chordate closest to the ancestral form of vertebrates, and in a key position to reveal essential aspects of the evolution of the brain Bauplan of vertebrates. The dorsal neural cord of this species at the larval stage is characterized by a small cerebral vesicle at its anterior end and a large posterior region. The latter is comparable in some aspects to the hindbrain and spinal cord regions of vertebrates. The rostral end of the cerebral vesicle contains a median pigment spot and associated rows of photoreceptor and other nerve cells; this complex is known as “the frontal eye. ” However, this is not a complete eye in the sense that it has neither eye muscles nor lens (only a primitive retina‐like tissue). Cranial nerves III, IV, and VI take part in the motor control of eye muscles in all vertebrates. Using a recent model that postulates distinct molecularly characterized hypothalamo‐prethalamic and mesodiencephalic domains in the early cerebral vesicle of amphioxus, we analyze here possible scenarios for the origin from the common ancestor of cephalochordates and vertebrates of the cranial nerves related with extrinsic eye muscle innervations.

Structural Analysis of Exosomes Using Different Types of Electron Microscopy

Interest in exosomes as biomarkers for early diagnosis of a disease is rapidly increasing because exosomes contain specific proteins or genetic material that represent the functions of their original cells (Thery, 2011). It is not easy to characterize exosomes because among extracellular vesicles, shed microvesicles (100~1,000 nm) have a size similar to exosomes (40~150 nm) (Villarroya-Beltri et al., 2014; Vlassov et al., 2012). In addition, because exosomes have various sizes and morphologies depending on their origin and function, they need to be analyzed using electron microscopy (EM). Currently, the cup shape of exosomes identified through negative staining has been considered to be their typical structure (Gyorgy et al., 2011; Thery et al., 2009). However, scanning EM (SEM) (Enderle et al., 2015), atomic force microscopy (Sharma et al., 2010), and cryo-transmission EM (TEM) (Montaner-Tarbes et al., 2016; Saari et al., 2015) revealed that exosomes have a round shape. In this study, we investigated the structure of exosomes using various EM approaches, including block preparation, sectioning, focused ion beam (FIB)-SEM, electron tomography, and cryo-TEM.

Metabolome Integrated Analysis of High-Temperature Response in Pinus radiata

The integrative omics approach is crucial to identify the molecular mechanisms underlying high-temperature response in non-model species. Based on future scenarios of heat increase, Pinus radiata plants were exposed to a temperature of 40°C for a period of 5 days, including recovered plants (30 days after last exposure to 40°C) in the analysis. The analysis of the metabolome using complementary mass spectrometry techniques (GC-MS and LC-Orbitrap-MS) allowed the reliable quantification of 2,287 metabolites. The analysis of identified metabolites and highlighter metabolic pathways across heat time exposure reveal the dynamism of the metabolome in relation to high-temperature response in P. radiata, identifying the existence of a turning point (on day 3) at which P. radiata plants changed from an initial stress response program (shorter-term response) to an acclimation one (longer-term response). Furthermore, the integration of metabolome and physiological measurements, which cover from the photosynthetic state to hormonal profile, suggests a complex metabolic pathway interaction network related to heat-stress response. Cytokinins (CKs), fatty acid metabolism and flavonoid and terpenoid biosynthesis were revealed as the most important pathways involved in heat-stress response in P. radiata, with zeatin riboside (ZR) and isopentenyl adenosine (iPA) as the key hormones coordinating these multiple and complex interactions. On the other hand, the integrative approach allowed elucidation of crucial metabolic mechanisms involved in heat response in P. radiata, as well as the identification of thermotolerance metabolic biomarkers (L-phenylalanine, hexadecanoic acid, and dihydromyricetin), crucial metabolites which can reschedule the metabolic strategy to adapt to high temperature.
ClassiNet -- Predicting Missing Features for Short-Text Classification

Short and sparse texts such as tweets, search engine snippets, product reviews, and chat messages are abundant on the Web. Classifying such short-texts into a pre-defined set of categories is a common problem that arises in various contexts, such as sentiment classification, spam detection, and information recommendation. The fundamental problem in short-text classification is feature sparseness -- the lack of feature overlap between a trained model and a test instance to be classified. We propose ClassiNet -- a network of classifiers trained for predicting missing features in a given instance, to overcome the feature sparseness problem. Using a set of unlabeled training instances, we first learn binary classifiers as feature predictors for predicting whether a particular feature occurs in a given instance. Next, each feature predictor is represented as a vertex vi in the ClassiNet, where a one-to-one correspondence exists between feature predictors and vertices. The weight of the directed edge eij connecting a vertex vi to a vertex vj represents the conditional probability that given vi exists in an instance, vj also exists in the same instance. We show that ClassiNets generalize word co-occurrence graphs by considering implicit co-occurrences between features. We extract numerous features from the trained ClassiNet to overcome feature sparseness. In particular, for a given instance x, we find similar features from ClassiNet that did not appear in x, and append those features in the representation of x. Moreover, we propose a method based on graph propagation to find features that are indirectly related to a given short-text. We evaluate ClassiNets on several benchmark datasets for short-text classification. Our experimental results show that by using ClassiNet, we can statistically significantly improve the accuracy in short-text classification tasks, without having to use any external resources such as thesauri for finding related features.
A Novel Type of Chaotic Attractor for Quadratic Systems Without Equilibriums

In this paper, a new chaotic dynamic system without equilibriums is presented. A conducted research of the qualitative properties of the discovered system reveals a noncompliance between the bifurcation behavior of the system and the Feigenbaum–Sharkovskii–Magnitsky theory. Additional research of known systems confirms the discrepancy.
Berry Phenolic Antioxidants – Implications for Human Health?

Antioxidants present in the diet may have a significant effect on the prophylaxis and progression of various diseases associated with oxidative stress. Berries contain a range of chemical compounds with antioxidant properties, including phenolic compounds. The aim of this review article is to provide an overview of the current knowledge of such phenolic antioxidants, and to discuss whether these compounds may always be natural gifts for human health, based on both in vitro and in vivo studies. It describes the antioxidant properties of fresh berries (including aronia berries, grapes, blueberries, sea buckthorn berries, strawberries and other berries) and their various products, especially juices and wines. Some papers report that these phenolic compounds may sometimes behave like prooxidants, and sometimes demonstrate both antioxidant and prooxidant activity, while others note they do not behave the same way in vitro and in vivo. However, no unwanted or toxic effects (i.e., chemical, hematological or urinary effect) have been associated with the consumption of berries or berry juices or other extracts, especially aronia berries and aronia products in vivo, and in vitro, which may suggest that the phenolic antioxidants found in berries are natural gifts for human health. However, the phenolic compound content of berries and berry products is not always well described, and further studies are required to determine the therapeutic doses of different berry products for use in future clinical studies. Moreover, further experiments are needed to understand the beneficial effects reported so far from the mechanistic point of view. Therefore, greater attention should be paid to the development of well-controlled and high-quality clinical studies in this area.
Identification of Single Nucleotide Polymorphisms Regulating Peripheral Blood mRNA Expression with Genome-Wide Significance: An eQTL Study in the Japanese Population

Several recent studies have reported that expression quantitative trait loci (eQTLs) may affect gene expression in a cell-dependent manner. In the current study, a genome-wide eQTL analysis was performed in whole blood samples collected from 76 Japanese subjects. RNA microarray analysis was performed for 3 independent sample groups that were genotyped in a genome-wide scan. The correlations between the genotypes of 534,404 autosomal single nucleotide polymorphisms (SNPs) and the expression levels of 30,465 probes were examined for each sample group. The SNP-probe pairs with combined correlation coefficients of all 3 sample groups corresponding to P<3.1×10−12 (i.e., Bonferroni-corrected P<0.05) were considered significant. SNP-probe pairs with a high likelihood of cross-hybridization and SNP-in-probe effects were excluded to avoid false positive results. We identified 102 cis-acting and 5 trans-acting eQTL regions. The cis-eQTL regions were widely distributed both upstream and downstream of the gene, as well as within the gene. The eQTL SNPs identified were examined for their influence on the expression levels in lymphoblastoid cell lines by using a public database. The results showed that genetic variants affecting expression levels in whole blood may have different effects on gene expression in lymphoblastoid cell lines. Further studies are required to clarify how SNPs function in affecting the expression levels in whole blood as well as in other tissues.
Pertussis epidemiology in Argentina: TRENDS after the introduction of maternal immunisation

Abstract Data on the impact of the recently recommended maternal pertussis vaccination are promising, but still insufficient to universalise this approach. We thus compared the epidemiological data prior to the implementation of this vaccination strategy in Argentina (2012) with the figures reported after 2012. During that 2010–2016 period, two outbreaks occurred, one in 2011 and another in 2016. In the former, the incidence was 6.9/100 000 inhabitants and the case-fatality rate 2.6%. Thereafter, a decline in incidence was detected until 2014. During 2015 and 2016 an increase in the incidence transpired, but this rise was fortunately not accompanied by one in the case fatality ratio. Indeed, in 2016 the case fatality ratio was the lowest (0.6%). Moreover, during the 2016 outbreak, the incidence (3.9/100 000 inhabitants) and the case severity detected in the most vulnerable population (infants 0–2 months) were both lower than those in 2011. Consistent with this pattern, in 2016, in the most populated province of Argentina (Buenos Aires), the case percentage with laboratory-positive results indicating a high number of symptoms (59.1% of the total cases) diminished compared with that detected in the 2011 outbreak without maternal immunisation (71.9%). Using the mathematical model of pertussis transmission we previously designed, we assessed the effect of vaccination during pregnancy on infant incidence. From comparisons between the epidemiological data made through calculations, emerged the possibility that vaccinating women during pregnancy would benefit the infants beyond age 2 months, specifically in the 2–12-month cohort.
Review Article Relationships between intuitive eating and health indicators: literature review

Abstract Objective To review the peer-reviewed literature on relationships between intuitive eating and health indicators and suggest areas of inquiry for future research. We define the fundamental principles of intuitive eating as: (i) eating when hungry; (ii) stopping eating when no longer hungry/full; and (iii) no restrictions on types of food eaten unless for medical reasons. Design We include articles cited by PubMed, PsycInfo and Science Direct published in peer-reviewed journals or theses that include ‘intuitive eating’ or related concepts in the title or abstract and that test relationships between intuitive eating and physical or mental health indicators. Results We found twenty-six articles that met our criteria: seventeen cross-sectional survey studies and nine clinical studies, eight of which were randomised controlled trials. The cross-sectional surveys indicate that intuitive eating is negatively associated with BMI, positively associated with various psychological health indicators, and possibly positively associated with improved dietary intake and/or eating behaviours, but not associated with higher levels of physical activity. From the clinical studies, we conclude that the implementation of intuitive eating results in weight maintenance but perhaps not weight loss, improved psychological health, possibly improved physical health indicators other than BMI (e.g. blood pressure; cholesterol levels) and dietary intake and/or eating behaviours, but probably not higher levels of physical activity. Conclusions Research on intuitive eating has increased in recent years. Extant research demonstrates substantial and consistent associations between intuitive eating and both lower BMI and better psychological health. Additional research can add to the breadth and depth of these findings. The article concludes with several suggestions for future research.
Diagnostic Value of Nasal Cytology in Chronic Rhinosinusitis Assessed by a Liquid-based Cytological Technique

Back ground: Nasal cytology has generally been employed as a useful diagnostic tool in the differentiation of rhinopathies. Objective The aim of this study was to assess the extent and diagnostic value of inflammation of nasal and paranasal sinus mucosa in chronic rhinosinusitis patients by employing a combination of nasal brushings and a liquid-based cytological technique. Methods Forty-eight patients with chronic sinusitis and 20 control subjects without any sign of sinusitis undergoing endoscopic surgery, although not all underwent endoscopic sinus surgery, were recruited to the study. Nasal cytology samples were collected from all subjects using nasal brush and processed a liquid-based cytological technique for evaluation of total and differential inflammatory cell counts. Biopsies were also taken from the inferior turbinates from its anterior margin in all subjects and from identical lateral maxillary sinus mucosa in patients with chronic sinusitis during surgery and routinely processed for staining and evaluation of inflammatory cells. Results Total and individual inflammatory cell counts in nasal brushings were significantly correlated with the respective inflammatory cell counts in biopsies obtained from the inferior turbinate (eosinophils: r = .519 and P = .016; neutrophils: r = .540 and P = .012; lymphocytes: r = .540 and P = .011) but not in biopsies obtained from the maxillary sinus. No correlation was observed between the inflammatory cells in biopsies from the inferior turbinate and biopsies from the maxillary sinus. The liquid-based cytological technique showed higher sensitivity (94.1%), specificity (76.9%), and positive predictive value (84.2%) for inflammation in the inferior turbinates than for inflammation in the maxillary sinus (sensitivity = 63.4% and positive predictive value = 63.4%). Conclusion Nasal cytology evaluated by use of nasal brushings processed by a liquid-based cytological technique is likely to have higher diagnostic value for the inflammatory response in noninfectious rhinitis than in chronic rhinosinusitis.
Airway stenting for patients with airway stenosis because of small cell lung cancer

Airway stenting has been reported to be useful for patients with malignant airway stenosis as a bridge to tumour‐specific therapy, such as chemotherapy and radiation therapy, as well as palliative therapy. However, its role in patients with small‐cell lung cancer (SCLC), the most aggressive lung cancer subtype, is unclear. We investigated the efficacy of airway stenting for patients with airway stenosis resulting from SCLC.
