Opinion representative of cosmetic products

The purpose of this research is to summarize customer reviews of cosmetic products that were written in Thai by using sentiment analysis technics. We expect that text summarization system will help refine the results from customer review. The consumer will then be able to select the products that meet their needs while the cosmetic company will also have a chance to improve the quality of the products to meet the customers' need. We used the data from popular web sites, which has cosmetic products reviews. In this paper, the Naïve Bayes algorithm is used to classify the products while we classify the data as positive or negative polarity through opinion words used. Then Cosine similarity was used to find similar phrases. They were then ranked by PageRank algorithm and Hopfield Network algorithm to find the most important phrase. The performance of the program was measured with ROUGE and can be concluded that the data which were tested in the Hopfield algorithm has the highest accuracy at 0.82040, from ROUGE-1 performance measurement.
Clinical Practice Patterns of Radiotherapy in Patients with Hepatocellular Carcinoma: A Korean Radiation Oncology Group Study (KROG 14-07)

Purpose The aim of this study was to examine patterns of radiotherapy (RT) in Korean patients with hepatocellular carcinoma (HCC) according to the evolving guideline for HCC established by the Korean Liver Cancer Study Group-National Cancer Center (KLCSG-NCC). Materials and Methods We reviewed 765 patients with HCC who were treated with RT between January 2011 and December 2012 in 12 institutions. Results The median follow-up period was 13.3 months (range, 0.2 to 51.7 months). Compared with previous data between 2004 and 2005, the use of RT as a first treatment has increased (9.0% vs. 40.8%). Increased application of intensity-modulated RT resulted in an increase in radiation dose (fractional dose, 1.8 Gy vs. 2.5 Gy; biologically effective dose, 53.1 Gy10 vs. 56.3 Gy10). Median overall survival was 16.2 months, which is longer than that reported in previous data (12 months). In subgroup analysis, treatments were significantly different according to stage (p < 0.001). Stereotactic body RT was used in patients with early HCC, and most patients with advanced stage were treated with three-dimensional conformal RT. Conclusion Based on the evolving KLCSG-NCC practice guideline for HCC, clinical practice patterns of RT have changed. Although RT is still used mainly in advanced HCC, the number of patients with good performance status who were treated with RT as a first treatment has increased. This change in practice patterns could result in improvement in overall survival.
Variation in individual walking behavior creates the impression of a Lévy flight

Many animal paths have an intricate statistical pattern that manifests itself as a power law-like tail in the distribution of movement lengths. Such distributions occur if individuals move according to a Lévy flight (a mode of dispersal in which the distance moved follows a power law), or if there is variation between individuals such that some individuals move much farther than others. Distinguishing between these two mechanisms requires large quantities of data, which are not available for most species studied. Here, we analyze paths of black bean aphids (Aphis fabae Scopoli) and show that individual animals move in a predominantly diffusive manner, but that, because of variation at population level, they collectively appear to display superdiffusive characteristics, often interpreted as being characteristic for a Lévy flight.
A Binding Site for Multiple Transcriptional Activators in the fushi tarazu Proximal Enhancer Is Essential for Gene Expression In Vivo

ABSTRACT The Drosophila homeobox gene fushi tarazu(ftz) is expressed in a highly dynamic striped pattern in early embryos. A key regulatory element that controls theftz pattern is the ftz proximal enhancer, which mediates positive autoregulation via multiple binding sites for the Ftz protein. In addition, the enhancer is necessary for stripe establishment prior to the onset of autoregulation. We previously identified nine binding sites for multiple Drosophilanuclear proteins in a core 323-bp region of the enhancer. Three of these nine sites interact with the same cohort of nuclear proteins in vitro. We showed previously that the nuclear receptor Ftz-F1 interacts with this repeated module. Here we purified additional proteins interacting with this module from Drosophila nuclear extracts. Peptide sequences of the zinc finger protein Ttk and the transcription factor Adf-1 were obtained. While Ttk is thought to be a repressor of ftz stripes, we have shown that both Adf-1 and Ftz-F1 activate transcription in a binding site-dependent fashion. These two proteins are expressed ubiquitously at the timeftz is expressed in stripes, suggesting that either may activate striped expression alone or in combination with the Ftz protein. The roles of the nine nuclear factor binding sites were tested in vivo, by site-directed mutagenesis of individual and multiple sites. The three Ftz-F1–Adf-1–Ttk binding sites were found to be functionally redundant and essential for stripe expression in transgenic embryos. Thus, a biochemical analysis identifiedcis-acting regulatory modules that are required for gene expression in vivo. The finding of repeated binding sites for multiple nuclear proteins underscores the high degree of redundancy built into embryonic gene regulatory networks.
On the Riemann hypothesis

The purpose of this article is to entertain, and possibly to report a new result. Let ζ(s) and Γ(s) be the Riemann zeta function and the gamma function, respectively. From the original version of this math.GM/0507189, we have for − 1 2 < a < 1 2 and any positive real number t, |E(a, t)| ζ 1 2 + a + it − G(a, t) ζ 1 2 − a − it = 0, (1) where E(a, t) = 1 cos(πa 2) cos πq 2 2(2π) − 1 2 +a+it Γ 1 2 − a − it and G(a, t) = tan πa 2 + 1 cosh(πt) 2 + tanh 2 (πt). We shall consider the function W (a) = ζ 1 2 + a + it. Assume |E(a, t)| > G(a, t) 0 < a < 1 2 , t ≥ 13 , (2) and W (a 0) = W (−a 0) = 0. (3) Under these assumptions, we show the following lemma. Lemma 1. Let 0 < a < 1 2 and t ≥ 13 be a fixed positive real number. The global maximum of W (a) has a positive value, and can not exist over the interval (0, 1 2 − a 0). Proof. As ζ(s) is analytic for all s in the critical strip, it is also holomorphic in the critical strip. Hence W (a) is a nonnegative continuous function of a. Besides, since the number of zeros of ζ(s) in the critical strip with 0 < t < T is asymptotic to T ln T 2π as T → ∞ [1, pp. 293], there are finitely many zeros in the critical strip with 0 < t < T for each given T .
VANET privacy by “defending and attacking”

A major concern regarding Vehicular Ad Hoc Networks (VANETs) is the protection of the participants' privacy. Through the frequent transmission of beacons containing pseudonyms and telematic data like speed, acceleration and location of the vehicles, attackers are able to track VANET users. To address this problem, several privacy concepts have been proposed in the past to protect the participants. These concepts often work with a single centralized provider, require radio silence or are restricted to defense only. This can lead to weak protection or to major restrictions of VANET functionality. In this paper we propose the concept of “Defending and Attacking” to overcome these issues.
Theta lifting for some cohomologicaly induced representations

In his paper 'Theta lifting for representations with non zero cohomlogy', Jian-Shu Li proved that a certain kind of cohomological representations of $U(a,b)$ is automorphic. In this paper, this result is generalized to a more general class of cohomological representations of this group. It comes from the fact that these cohomological representations are the image by the theta correspondance of some representations obtained by cohomological induction. In proving this theorem, we also prove some cases of Adams conjecture.
AD-ESPRIT for multi-target localization in bistatic MIMO radar system

In this paper, an ESPRIT-based approach named as AD-ESPRIT is presented to jointly estimate the directions of arrival (DOAs) and directions of departure (DODs) estimation of interesting multi-targets for bistatic MIMO radar system. The proposed method does not need two-dimensional (2-D) or multiple 1-D spectrum peak searching. Thus, the computational complexity of the proposed algorithm is reduced for the direction finding cross localization in bistatic MIMO radar system. Furthermore, the estimated DODs and DOAs is automatically determined. Simulation results are presented to verify the effectiveness of the proposed method.
Applications of Orthogonal Arrays to Computer Science

Orthogonal arrays (OAs) are basic combinatorial structures, originally studied by statisticians motivated by their applications to design of experiments. In recent years, they have found numerous applications in com- puter science. Among their applications are derandomization of algorithms, random pattern testing of VLSI chips, authentication codes, universal hash functions, threshold schemes, and perfect local randomizers .

Experimental study on property of space charge for polyethylene doped with nano-powder

In this study, packet-like space charge behavior in linear low-density polyethylene (LLDPE) and LLDPE doped with two different nano-powder (Al2O3, MgO) were investigated by the pressure wave propagation (PWP). This paper focuses on the space charge dynamics and the isothermal decay process in LLDPE doped with Al2O3 and MgO by sligt concentration (0.01 wt%, 0.05 wt%, 0.1 wt%, 0.2 wt%, 0.5 wt%, 1 wt%). The 1mm sheet samples, sandwiched by semi-conductive electrodes, were submitted to DC high voltage of 40 kV/mm for 3 hours at 40 °C. The results show that, Al2O3/LLDPE with doping concentration more than 0.2 wt% can be effective to suppress the charge injection. For MgO/LLDPE sample, the value is 0.5 wt%.
Fatigue Status in Relation to Lifestyle in Healthy Japanese Adolescents

In order to investigate the prevalence of physical, mental, and chronic fatigue syndrome-(CFS-) related fatigue and its relation to lifestyle, 1,225 adolescents (591 males, 634 females) aged 11 to 16 years were asked to complete a self-reported questionnaire on fatigue status and lifestyle in the past one month. There was no gender difference in physical and mental fatigue scores, but CFS-related scores were significantly higher in females than in males. These scores were found to increase with the increase of age. After adjusting for age and gender, multiple regression analysis showed that physical and mental fatigue scores were associated with sleeping hours, extracurricular sports activity, food balance, the frequencies of snacks between regular meals, intake of sugar-sweetened beverages, and visits to the nurse's room. This paper is the first large cross-sectional study on fatigue in healthy adolescents in Japan, albeit there were numerous such studies in Western countries.
Turning From Parents: Psychological Distancing and Attachment-Related Changes in Regret for Immediate Contact in Emerging Adulthood

This longitudinal study examined how emerging adults psychologically distance themselves from parents. Every week during their first semester at college, participants (n = 71, M age = 18 years [SD = 0.48]) read hypothetical vignettes describing emotionally salient situations they could encounter at college. Participants then provided information about whether they would regret not being in immediate contact with parents versus peers when dealing with the aftermath of these situations. Results suggested that participants were separating themselves from parents in a dynamic manner over time, which was revealed in varying levels of regret for not possibly being in immediate contact with parents following emotional events. Moreover, compared to participants with negative representational models of parents, participants with positive models reported more consistent patterns of regret for not having immediate parental contact. This study provides new insights into normative attachment dynamics beyond childhood and how emerging adults reorganize their attachment hierarchies.
Progressive image coding using trellis coded quantization

In this work, we present coding techniques that enable progressive transmission when trellis coded quantization (TCQ) is applied to wavelet coefficients. A method for approximately inverting TCQ in the absence of least significant bits is developed. Results are presented using different rate allocation strategies and different entropy coders. The proposed wavelet-TCQ coder yields excellent coding efficiency while supporting progressive modes analogous to those available in JPEG.
Two-photon imaging of capillary blood flow in olfactory bulb glomeruli

Analysis of the spatiotemporal coupling between neuronal activity and cerebral blood flow requires the precise measurement of the dynamics of RBC flow in individual capillaries that irrigate activated neurons. Here, we use two-photon microscopy in vivo to image individual RBCs in glomerular capillaries in the rat dorsal olfactory bulb. We find that odor stimulation evokes capillary vascular responses that are odorant- and glomerulus-specific. These responses consist of increases as well as decreases in RBC flow, both resulting from independent changes in RBC velocity or linear density. Finally, measuring RBC flow with micrometer spatial resolution and millisecond temporal resolution, we demonstrate that, in olfactory bulb superficial layers, capillary vascular responses precisely outline regions of synaptic activation.
Comparison of cardiac troponin I immunoassays variably affected by circulating autoantibodies.

BACKGROUND We recently provided evidence that circulating autoantibodies against cardiac troponin I (cTnI) or the troponin complex cause negative interference in cTnI immunoassays. By comparing three cTnI immunoassays, we further explored the phenomenon of circulating autoantibodies and their consequences in patient samples. METHODS We developed a cTnI immunoassay with a novel assay design using three antibodies, two of which bind epitopes outside the stable, central part of cTnI. Samples from 541 chest pain patients were measured with the new cTnI assay and with a first-generation cTnI assay (Innotrac Aio cTnI) using a conventional midfragment assay design. Using another sample cohort, we also compared the new assay with a second-generation cTnI assay (Access AccuTnI). RESULTS The analytical detection limit of the new cTnI assay was 0.012 microg/L, and the lowest concentration giving a total imprecision (CV) of 10% was 0.060 microg/L. The mean difference (95% limits of agreement) between the new cTnI and Aio cTnI assays was larger in admission samples (21.0%; -107.8% to 149.7%) than in samples taken 6-12 h (12.8%; -61.5% to 87.2%) and 24 h after admission (3.0%; -71.3% to 77.4%; P <0.001). With the lowest concentrations giving 10% CV (0.22 microg/L for Aio cTnI) used as cutoffs, 14.3% (n = 76) of admission samples were positive only with the new assay, whereas 13.5% (n = 72) were positive with both assays. Of samples taken at 6-12 and 24 h, 10.2% (n = 31) and 8.3% (n = 29) were positive only with the new assay. ROC curve analysis of admission samples showed a significantly higher area under the curve for the new cTnI assay (0.940) than for the Aio cTnI assay (0.846; P <0.001). The new cTnI assay gave generally lower results than the AccuTnI assay; the mean (95% limits of agreement) differences were -58.9% (-151.8% to 34.0%) in admission samples. In samples with severe interference from autoantibodies, median ratios between the new assay and AccuTnI were higher than in samples with no apparent troponin autoantibodies (0.875 vs 0.481; P<0.001). CONCLUSIONS The new cTnI assay, which is based on a novel antibody combination different from the conventional midfragment antibody approach, offers improved detection of cTnI in samples containing troponin autoantibodies.
The challenges of joint attention

This article discusses the concept of joint attention and the different skills underlying its development. Research in developmental psychology clearly states that the development of skills to understand, manipulate and coordinate attentional behavior plays a pivotal role for imitation, social cognition and the development of language. However, beside the fact that joint attention has recently received an increasing interest in the robotics community, existing models concentrate only on partial and isolated elements of these phenomena. In the line of Tomasello’s research, we argue that joint attention is much more than simultaneous looking because it implies a shared intentional relation to the world. This requires skills for attention detection, attention manipulation, social coordination and, most importantly, intentional understanding. After defining joint attention and its challenges, the current state-of-the-art of robotic and computational models relevant for this issue is discussed in relation to a developmental timeline drawn from results in child studies. From this survey, we identify open issues and challenges that still need to be addressed to understand the development of the various aspects of joint attention and conclude with the potential contribution of robotic models.
APOE genotype and age modifies the correlation between cognitive status and metabolites from hippocampus by a 2D 1H-MRS in non-demented elders

Purpose. To examine the associations among age, Apolipoprotein E (APOE) genotype, metabolic changes in the hippocampus detected by 2D 1H magnetic resonance spectroscopy (MRS), and neuropsychological measures of cognition in non-demented elders. Materials and Methods. We studied a cohort of 16 cognitively normal controls (CN) and 11 amnestic mild cognitive impairment (aMCI) patients between 66 and 88 years old who were genotyped for APOE genetic polymorphism. Measurements of 2D1H-MRS metabolites were obtained in the hippocampus region. Adjusting by age among all subjects, the association between metabolic changes and cognitive function was measured by Spearman partial rank-order correlation. The effect of APOE status was measured by separating the subjects into APOE genotype subgroups, including the APOEε4 carriers and APOEε4 non-carriers. Results. In contrast to the CN group matched with age, gender, and education, aMCI patients showed increased myo-inositol (mI)/Creatine (Cr) ratio only in the right hippocampus. No differences were noted on N-acetylaspartate (NAA)/Cr and mI/NAA from bilateral hippocampus, and so was mI/Cr ratio in left hippocampus between aMCI and CN. The mI/Cr ratio from the right hippocampus in non-demented elders was negatively correlated with Montreal Cognitive Assessment (MoCA) scores. Whether ε4 genotype or age was added as a covariate, none of the correlation effects remained significant. Additionally, adjusting for age and APOE genotype together, there was no significant correlation between them. Conclusion. Since the higher mI/Cr from the right hippocampus of the patients with aMCI than those from CN, the mI/Cr could be a more specific predictor of general cognitive function in aMCI patients. There is an association between higher mI/Cr in right hippocampus and worse cognitive function for the non-demented older adults, and the correlation could be modified by APOE status and age. That provided a window on objectively understanding the mechanism between the brain metabolites and the influence factors in non-demented elders.
Body Memory: The change of Dungan people's Folk Life

Folklore is not always static, and the body constantly participates in the adaption in the process of displaying, remembering, and inventing folklore. The body helps folklore individuals adapt to the surrounding environment and seek group identity. The body is not only the target of folk disciplines, but also a distinctive symbol that expresses the value and significance of existence. The effectiveness and adaptability of folk life are manifested in the use and carrying of the body. After migrating from China, Dungan people became a multi-dimensional carrier who has an inherited traditions and new invented traditions in the exotic cultural space. The change of folk life can be found in the process of constructing the expression of its own body.
A collaborative filtering framework based on local and global similarities with similarity tie-breaking criteria

Collaborative Filtering is the most commonly used technique in Recommender Systems, based on the users ratings in order to identify similar profiles and suggest them items. However, because it depends essentially on direct similarity measures between users or items, it usually suffers from the sparsity problem. Upon this situation, a good alternative is using global similarities to enrich the users neighborhood by transitively connecting them together, even when they do not share any common ratings. In this paper, we investigated the use of both local and global similarity measures with the maximin distance algorithm, along with tie-breaking criteria for neighbors with equal similarity. Our experiments showed that the maximin distance algorithm in fact produces many equally similar global neighbors, and that the criteria set for deciding between them severely improved the results of the recommendation process.
Radio and infrared recombination studies of the southern massive star forming region G333.6−0.2

We present high spatial resolution radio and near-infrared hydrogen recombination line observations of the southern massive star-forming region G333.6 0.2. The 3.4-cm continuum peak is found slightly offset from the infrared source. The H90α spectra show for the first time a double peak profile at some positions. The complex velocity s tructure may be accounted for by champagne outflows, which may also explain the offset betw een the radio and infrared sources. The 2.17-µm Brγ image and H90α map are combined to construct an extinction map which shows a trend probably set by the blister nature of the H II region. The total number of Lyman continuum photons in the central 50-arcsec is estimated to be equivalent to that emitted by up to 19 O7V stars.
