Is it really about me?: message content in social awareness streams

In this work we examine the characteristics of social activity and patterns of communication on Twitter, a prominent example of the emerging class of communication systems we call "social awareness streams. " We use system data and message content from over 350 Twitter users, applying human coding and quantitative analysis to provide a deeper understanding of the activity of individuals on the Twitter network. In particular, we develop a content-based categorization of the type of messages posted by Twitter users, based on which we examine users' activity. Our analysis shows two common types of user behavior in terms of the content of the posted messages, and exposes differences between users in respect to these activities.
School Dropouts: Examining the Space of Reasons

Background: Dropping out of school is a worldwide phenomenon with drastic mental health consequences for children, families and society. Aim and Materials & Methods: This study examines school dropouts in one district in Kerala with an emphasis on looking at multiple reasons for the problem. Results: The most common “reason” was various Physical disorders (80, 21.8%) followed by Mental Retardation (77, 20.9%). Child labour (Employment) came last (30, 8.1%) as a “reason” while financial issues constituted 50 (13.6%). Family issues accounted for 63 (17.1%) and School-related issues 68 (18.5%). Conclusion: This study highlights the need to examine a space of reasons for this phenomenon with active involvement and coordination of multiple agencies to examine and support getting children back to school and prevent dropouts.
Gang Membership, Delinquent Peers, and Delinquent Behavior

Youth gangs are on the rise. Today they threaten virtually every major city, many small communities, and even rural areas. The Office of Juvenile Justice and Delinquency Prevention (OJJDP) is committed to helping communities overcome this problem, and an essential first step is understanding the factors that contribute to the growth of youth gangs and the relationship of gang membership to delinquency.
Composite Cyclotomic Fourier Transforms With Reduced Complexities

Discrete Fourier transforms (DFTs) over finite fields have widespread applications in digital communication and storage systems. Hence, reducing the computational complexities of DFTs is of great significance. Recently proposed cyclotomic fast Fourier transforms (CFFTs) are promising due to their low multiplicative complexities. Unfortunately, there are two issues with CFFTs: (1) they rely on efficient short cyclic convolution algorithms, which have not been sufficiently investigated in the literature and (2) they have very high additive complexities when directly implemented. To address both issues, we make three main contributions in this paper. First, for any odd prime p, we reformulate a p -point cyclic convolution as the product of a (p-1) × (p-1) Toeplitz matrix and a vector, which has well-known efficient algorithms, leading to efficient bilinear algorithms for p-point cyclic convolutions. Second, to address the high additive complexities of CFFTs, we propose composite cyclotomic Fourier transforms (CCFTs). In comparison to previously proposed fast Fourier transforms, our CCFTs achieve lower overall complexities for moderate to long lengths and the improvement significantly increases as the length grows. Third, our efficient algorithms for p-point cyclic convolutions and CCFTs allow us to obtain longer DFTs over larger fields, e.g., the 2047-point DFT over GF(211) and 4095-point DFT over GF(212) , which are first efficient DFTs of such lengths to the best of our knowledge. Finally, our CCFTs are also advantageous for hardware implementations due to their modular structure.
The topological K-theory of certain crystallographic groups

Let Gamma be a semidirect product of the form Z^n rtimes Z/p where p is prime and the Z/p-action on Z^n is free away from the origin. We will compute the topological K-theory of the real and complex group C*-algebra of Gamma and show that Gamma satisfies the unstable Gromov-Lawson-Rosenberg Conjecture. On the way we will analyze the (co-)homology and the topological K-theory of the classifying spaces BGamma and underbar{B}Gamma. The latter is the quotient of the induced Z/p-action on the torus T^n.
Shrinkage Behaviour of One and Two Part Alkali-Activated Mortars: Factors and Mitigation Techniques

Alkali-Activated Binders (AABs) are promoted as sustainable alternatives to ordinary Portland cement (OPC) due to their promising characteristics and ability to reduce the global greenhouse emissions of construction materials. Despite many years of research, volumetric stability (i.e. shrinkage) of AABs, which has been scarcely investigated, is hindering their wider implementation in the construction sector. Hence, the initial attempt of the current study is to fully characterize and understand the shrinkage behaviour of AABs considering different factors. These factors included precursor materials, activator types and concentrations, and curing temperatures. Moreover, the effectiveness of shrinkage reducing admixtures (SRA) as a shrinkage mitigation technique and its interaction with AABs were evaluated. Two preparation methods for AABs, namely one-part (i.e. powder binder-powder activator) and two-part (i.e. powder binder-liquid activator), were also tested for comparison. Fresh properties including workability, setting behaviour, and heat evolution along with hardened properties (i.e. compressive strength) were explored. Results revealed that shrinkage for fly ash-based alkali-activated mortars was the lowest followed by blended fly ash/ slag, while alkali-activated slag-based mortars exhibited the highest values. Regardless of the preparation method, the higher the activator concentration, the higher the shrinkage. There is a strong link between AAB’s matrix rigidity and shrinkage behaviour. For both preparation methods, SRA was more effective in reducing shrinkage strains for slag-based alkali-activated mortars at different temperatures. Similar to OPC, SRA addition had induced a reduction in the compressive strength for all tested ABBs mixtures. However, the reduction in AABs mixtures strength was significantly lower than that for OPC mixtures.
Investigation of Microphysical Processes Occurring in Isolated Convection during NAME

AbstractA major objective of the North American Monsoon Experiment (NAME) was to quantify microphysical processes within convection occurring near the steep topography of northwestern Mexico. A previous study compared examples of isolated convection using polarimetric radar data and noted a dependence on mixed-phase processes via drop freezing and subsequent riming growth along the coastal plain and western slopes, with an even greater role of melting ice in rainfall production over the highest terrain. Despite the higher frequency of these isolated cells compared to organized convective systems, the latter were responsible for 75% of rainfall. Therefore, this study seeks to evaluate the role of mesoscale organization on microphysical processes and describes the evolution of these systems as a function of topography.Similar to isolated convection, both warm-rain and ice-based processes played important roles in producing intense rainfall in organized convection. Although similarities existed between cell .
Plasma Adiponectin and Soluble Leptin Receptor and Risk of Colorectal Cancer: A Prospective Study

Adipokines are adipocyte-secreted hormones that may mediate the etiologic link between obesity and colorectal cancer; however, the evidence from large prospective studies is limited. We prospectively evaluated the association of plasma adiponectin and soluble leptin receptor (sOB-R) with colorectal cancer risk within the Nurses' Health Study (1990–2008) and the Health Professionals Follow-up Study (1994–2008) among 616 incident colorectal cancer cases and 1,205 controls selected using risk-set sampling and matched on age and date of blood draw. In unconditional logistic regression with adjustment for matching factors and multiple risk factors, plasma adiponectin was significantly associated with reduced risk of colorectal cancer among men, but not among women. Compared with men in the lowest quartile of adiponectin, men in the highest quartile had a relative risk (RR) for colorectal cancer of 0.55 [95% confidence interval (CI), 0.35–0.86; Ptrend = 0.02]. The corresponding RR in women was 0.96 (95% CI, 0.67–1.39; Ptrend = 0.74). Plasma sOB-R was not associated with overall colorectal cancer risk in either men or women. A significant heterogeneity was noted in the association between sOB-R and colorectal cancer by subsite in women (Pheterogeneity = 0.004); sOB-R was significantly associated with increased risk of rectal cancer but not colon cancer. These findings support a role for adiponectin in colorectal carcinogenesis in men. Further studies are warranted to confirm these associations and elucidate potential underlying mechanisms.

Studies in bullous diseases. Treatment of pemphigus vulgaris with immunosuppressives (steroids and methotrexate) and leucovorin calcium.

Thirteen patients with pemphigus vulgaris were treated over a period of months or years with a combination of steroids and methotrexate. Antiepithelial antibodies were reduced in titer with the administration of these drugs. In ten of 13 patients side effects of methotrexate were quite severe despite low dosages. Methotrexate in adequate amounts would have been discontinued had not the use of leucovorin calcium, the specific antidote for methotrexate, been added as part of therapy. When leucovorin calcium was administered at intervals of one-half to three hours after injection of methotrexate, immunosuppressive action of methotrexate could be maintained in a majority of patients. In our experience flexibility in administration of the use of methotrexate alone or in combination with steroids and leucovorin calcium is recommended in the treatment of pemphigus.
Plasma melatonin and insulin‐like growth factor‐1 responses to dim light at night in dairy heifers

Abstract: The effect of dim (5, 10 and 50 1x) light at night on night plasma melatonin level (NML) and night plasma insulin‐like growth factor‐1 (IGF‐1) level was determined in 12 prepubertal Holstein heifers (245 ± 16 days age) using a 4 × 4 Latin Square design with 14‐day treatment and 14‐day recovery periods. Blood samples were collected at 23:00 hr (prior to the 8 hr night treatment which commenced at mid‐night) on days 0, 3 and 13, and throughout the night at 01:00, 02:00, 03:00, 04:00, 06:00 and 08:00 hr on days 1, 4 and 14 of treatment. Plasma was analysed by radioimmunoassay for melatonin (all samples) and IGF‐1 (samples for day 14, 04:00 hr only). Treatment (P = 0.03) and treatment × time (P = 0.02) were significant for NML. Exposure to 50 lx suppressed NML by 50% during the initial 2 hr of the night, but not thereafter. Exposure to 5 and 10 lx had no effect on NML. The NML response to 50 lx was found on all treatment days studied (treatment × time × day; P = 0.99). There was no treatment effect on plasma IGF‐1 level (P = 0.89), but plasma IGF‐1 level was higher (P = 0.001) during period 4. Plasma IGF‐1 level and NML tended (P = 0.10) to be negatively correlated. Light intensities of 10 lx or less appear safe for use at night in dairy barns where darkness is recommended.
Player Goal Recognition in Open-World Digital Games with Long Short-Term Memory Networks

Recent years have seen a growing interest in player modeling for digital games. Goal recognition, which aims to accurately recognize players' goals from observations of low-level player actions, is a key problem in player modeling. However, player goal recognition poses significant challenges because of the inherent complexity and uncertainty pervading gameplay. In this paper, we formulate player goal recognition as a sequence labeling task and introduce a goal recognition framework based on long short-term memory (LSTM) networks. Results show that LSTM-based goal recognition is significantly more accurate than previous state-of-the-art methods, including n-gram encoded feedforward neural networks pre-trained with stacked denoising autoencoders, as well as Markov logic network-based models. Because of increased goal recognition accuracy and the elimination of labor-intensive feature engineering, LSTM-based goal recognition provides an effective solution to a central problem in player modeling for open-world digital games.
HLA ANTIGENS IN ASIAN INDIAN PATIENTS WITH Graves'DISEASE

A study of 57 Asian Indian patients with Graves'disease revealed a significant increase in the frequency of HLA‐DQW2 (61.4%) as compared to the control population (22.6%) giving a relative risk of 5.4. Less prominent but statistically significant increase in the frequency of HLA‐A10 (29.8% patients as opposed to 10.5% controls) and HLA‐B8 (28.1% patients as opposed to 8.7% controls) was also observed. Further, patients carrying the phenotypes HLA‐A10 and HLA‐B8 were more prone to develop the disease at a younger age. Two HLA haplotypes, namely A10‐B8 and B8‐DR3, were found in significant linkage disequilibrium in our patients with Graves'disease. Patients carrying these haplotypes also had a tendency to develop the disease at an earlier age.
Structural Transformation Among the Aggregate Forms of Bacteriochlorophyll c as Determined by Electronic‐Absorption and NMR Spectroscopies: Dependence on the Stereoisomeric Configuration and on the Bulkiness of the 8‐C Side Chain ‡

Transformation among the aggregate forms of bacteriochlorophyll (BChl) c characterized by the wavelength of the Qy absorption, i.e. the dimer (B675), B705, B720 and B745, was traced by electronic‐absorption spectroscopy for each of the isomers including R[E,E], R[P,E], R[I,E], S[P,E] and S[I,E] suspended in the mixtures of methylene chloride and n‐hexane. A combination of NMR spectroscopy determining the structural motifs and calculation of the shift of the Qy absorption reflecting the long‐range transition dipole–transition dipole interactions among the macrocycles in the entire aggregate structures proposed the following models: B705d (B705d′), a linear array of straight (inclined) columns consisting of a pair of the piggyback dimers; B720d and B745d, an assembly of two and five shifted‐inclined columns consisting of more than six piggyback dimers; and B720m and B745m, an assembly of one and two parallel stepwise stacking of ∼30 monomers. Calculations of the steric energies rationalized two different pathways of transformations: the dimer → B705d (B705d′) → B720d → B745d for the R isomers; and the monomer → (B720m) → B745m for the S isomers. Addition of S[I,E] seems to trigger the B745d → B745m transformation of the R isomers.
Chlamydomonas ODA10 is a conserved axonemal protein that plays a unique role in outer dynein arm assembly

In vivo, assembly of axonemal dyneins into cilia is a multi-step process. We show that Chlamydomonas ODA10 encodes an axonemal protein required for a late step in outer arm dynein assembly. Once dynein arms have assembled, they can be extracted and the ODA10p protein is no longer required for high-affinity binding onto axonemal binding sites.
Lack of association between polymorphisms in p53 gene and spermatogenetic failure in a Chinese population

Although various genetic factors have been demonstrated in human male infertility, many genetic causes involving gene variants for the idiopathic male infertility have not yet been elucidated. P53 gene is involved in the meiosis of the male rat and mice, which suggested that p53 plays a critical role in spermatogenesis. To examine whether the codon72 polymorphism and IVS7 + 72C>T polymorphism of the human p53 gene are associated with spermatogenetic failure in Han‐Chinese population. A case–control study was conducted with 198 idiopathic infertile patients with nonobstructive azoospermia or severe oligozoospermia and 233 fertile controls. We genotyped the two polymorphisms, codon72 and IVS7 + 72C>T, using polymerase chain reaction‐restriction fragment length polymorphism assay. The polymorphisms were identified in both infertile patients and fertile controls. The allele and genotype frequencies of the two polymorphisms were not significantly different between the patients and controls. Further analysis showed that there was no statistically significant difference in the haplotype distributions between the patients and controls. The results of this study suggest that the codon72 and IVS7 + 72C>T polymorphisms of the p53 gene are unlikely to contribute to the pathogenesis of idiopathic male infertility with spermatogenetic failure.
The heat flux and the temperature gradient in the lower atmosphere

Most parameterizations used in Large Eddy Simulations of the atmospheric boundary layer are based on the assumption that subgrid‐scale fluxes are aligned against spatial gradients of transported quantities (down‐gradient closures). Based on field experiments, we determine the distribution and most probable relative orientations of the subgrid‐scale (SGS) heat flux relative to parameterizations based on the temperature gradient. We show that, under neutral and unstable atmospheric stability, the SGS heat flux most likely lies within the geometric span of the so called mixed tensor eddy diffusivity model.
Heparin-Binding Hemagglutinin Induces IFN-γ+ IL-2+ IL-17+ Multifunctional CD4+ T Cells during Latent but Not Active Tuberculosis Disease

ABSTRACT The mycobacterial heparin-binding hemagglutinin (HBHA) protein induces a potent gamma interferon (IFN-γ) response in latent tuberculosis (TB) infection and is a candidate vaccine and diagnostic antigen. We have assessed HBHA-specific intracellular IFN-γ, interleukin-2 (IL-2), and IL-17 production by CD4+ T cells in TB cases and household contacts (HHCs) as well as the level of secreted IFN-γ in whole-blood culture supernatant. HHCs were further classified as tuberculin skin test (TST) positive or negative, and the group was also divided as HIV positive or negative. Our study revealed that HBHA induces multifunctional IFN-γ-, IL-2-, and IL-17-coexpressing CD4+ T cells in HHCs but not in active TB cases; however, IFN-γ levels in culture supernatant did not differ between participant groups. Further studies are needed to completely understand how HBHA induces immune responses in different disease groups.
Frontal brain electrical activity (EEG) distinguishes valence and intensity of musical emotions

Using recent regional brain activation/emotion models as a theoretical framework, we examined whether the pattern of regional EEG activity distinguished emotions induced by musical excerpts which were known to vary in affective valence (i.e., positive vs. negative) and intensity (i.e., intense vs. calm) in a group of undergraduates. We found that the pattern of asymmetrical frontal EEG activity distinguished valence of the musical excerpts. Subjects exhibited greater relative left frontal EEG activity to joy and happy musical excerpts and greater relative right frontal EEG activity to fear and sad musical excerpts. We also found that, although the pattern of frontal EEG asymmetry did not distinguish the intensity of the emotions, the pattern of overall frontal EEG activity did, with the amount of frontal activity decreasing from fear to joy to happy to sad excerpts. These data appear to be the first to distinguish valence and intensity of musical emotions on frontal electrocortical measures.
Process Standardization of Whey Protein Enriched Spiced Quarg Cheese

All over the world people consume fermented foods not only for nutrition but also for its potential health benefits. Fermented milk contains all the milk components modified through the process of fermentation by lactic acid bacteria. The conversion of part of lactose to lactic acid during fermentation, destabilize the casein by lowering the pH and their by enhance the digestability (Prajapati et al., 2017). The process of fermentation results in production of antibacterial effect such as organic acids, bacteriocins, hydrogen peroxide, fatty acids etc, which are said to impart health benefits by dealing with the pathogens. Cheese is the generic name for group of fermented milk based food products, produced in a great range of flavour and forms throughout the world (Fox et al., 1992). FAO records the cheese production in India at 1500 tones at against the global production of 7832 tones in 2016 (www.faostat.fao.org). Cheese is held in high esteem in the food system and in food chain owing to its excellent portability, long life and good nutritive value (Bhongale et al., 2016). There are more than 2000 varieties of cheese, although many have little International Journal of Current Microbiology and Applied Sciences ISSN: 2319-7706 Volume 7 Number 06 (2018) Journal homepage: http://www.ijcmas. com
Methane production from protozoan endosymbionts following stimulation of microbial metabolism within subsurface sediments

Previous studies have suggested that protozoa prey on Fe(III)- and sulfate-reducing bacteria that are enriched when acetate is added to uranium contaminated subsurface sediments to stimulate U(VI) reduction. In order to determine whether protozoa continue to impact subsurface biogeochemistry after these acetate amendments have stopped, 18S rRNA and ß-tubulin sequences from this phase of an in situ uranium bioremediation field experiment were analyzed. Sequences most similar to Metopus species predominated, with the majority of sequences most closely related to M. palaeformis, a cilitated protozoan known to harbor methanogenic symbionts. Quantification of mcrA mRNA transcripts in the groundwater suggested that methanogens closely related to Metopus endosymbionts were metabolically active at this time. There was a strong correlation between the number of mcrA transcripts from the putative endosymbiotic methanogen and Metopus ß-tubulin mRNA transcripts during the course of the field experiment, suggesting that the activity of the methanogens was dependent upon the activity of the Metopus species. Addition of the eukaryotic inhibitors cyclohexamide and colchicine to laboratory incubations of acetate-amended subsurface sediments significantly inhibited methane production and there was a direct correlation between methane concentration and Metopus ß-tubulin and putative symbiont mcrA gene copies. These results suggest that, following the stimulation of subsurface microbial growth with acetate, protozoa harboring methanogenic endosymbionts become important members of the microbial community, feeding on moribund biomass and producing methane.
Smell and Taste Dysfunction as Early Markers for Neurodegenerative and Neuropsychiatric Diseases

During the last few decades a significant literature has evolved, suggesting that sensory dysfunction, particularly smell and taste dysfunction, can be early markers for neurodegenerative diseases such as Parkinson’s and Alzheimer’s and neuropsychiatric diseases including ADHD and Schizophrenia, all diseases that involve dopaminergic pathology. Smell loss and taste dysfunction appear in clinical versus non-clinical groups, and in longitudinal studies these symptoms have been noted years earlier than motor signs in the first degree relatives of individuals who already have the diseases. This paper is a review of the recent literature on empirical studies and reviews that have documented the results of sensory screenings of several groups with neurodegenerative and neuropsychiatric diseases and those first-degree relatives at risk for those diseases. Although early biomarkers could be useful in identifying those needing preventive intervention, the treatment literature is very limited.
