NON-INTERFERING SEQUENCE FOR MASSIVE DATA TRAFFIC IN LOW-POWER LOSSY NETWORKS

Techniques are described herein for generating a non-interfering sequence. This mechanism mainly comprises two steps. The first step involves computing and generating a schedule, and the second step involves receiving metering data from all nodes. After the second step ends, the head end system builds a residual node set containing all nodes that failed to report data in a given schedule, and then the first and second steps are repeated until the residual set is empty. The two steps are performed serially. The techniques described herein optimize these two steps. In particular, first a system mathematical mode is built from a Routing Protocol for Low-Power and Lossy Networks (RPL) p-table and link neighbor, second the constraint condition is constructed, and third the parameter is adjusted and the schedule is implemented

Assessing Impulsivity in Chinese: Elaborating Validity of BIS Among Male Prisoners

This study was carried out to test the factor structure and psychometric properties of the Barratt Impulsiveness Scale–Version 11 (BIS-11), and its short versions (the eight-item and 15-item BIS) in a sample of 424 Chinese male prisoners (M = 31.26, SD = 7.43, age = 18-52 years). Confirmatory factor analysis (CFAs) indicated that the single-factor model of BIS with eight items (BIS-8) and the three-factor model of BIS with 15 items (BIS-15) fit the data well. In addition, the item response theory (IRT) approach confirmed the construct and items for the BIS-8 with good discrimination, threshold parameters, and test information curve. Correlations with psychopathic traits, antisocial personality disorder, and aggression suggested that the performance of the eight-item BIS was comparable with that of the original 30-item BIS in measuring general impulsivity.This research was supported by grants from the National Natural Science Foundation of China (Grant 31400904) and Guangzhou University’s 2017 training program for top-notch young people (Grant BJ201715)

Assessing the Measurement Invariance of the Inventory of Callous-Unemotional Traits in School Students in China and the United Kingdom

The current study investigated the measurement invariance of the Inventory of Callous-Unemotional Traits in school-attending youth in the UK (N = 437) and China (N = 364). The original 24-item ICU and five shortened versions proposed in previous studies were tested and compared using confirmatory factor analysis in the UK sample. Results indicated that the original ICU was a poor fit in the UK sample. A shortened, 11-item version (ICU-11) featuring two factors (Callousness and Uncaring) provided the best fit and was invariant across gender in both the UK and Chinese samples. Comparisons of the ICU-11 in UK and Chinese school children revealed a similar item-factor combination and factor loadings, but different item thresholds. Findings indicate that the ICU-11 may be a preferable alternative to the original version, but that average ICU-11 scores may have a different meaning in the UK and China.The Chinese sample data collection was funded by the National Natural Science Foundation of China (Grant No. 31400904).

A Two-Year Surveillance of 2009 Pandemic Influenza A (H1N1) in Guangzhou, China: From Pandemic to Seasonal Influenza?

In this two-years surveillance of 2009 pandemic influenza A (H1N1) (pH1N1) in Guangzhou, China, we reported here that the scale and duration of pH1N1 outbreaks, severe disease and fatality rates of pH1N1 patients were significantly lower or shorter in the second epidemic year (May 2010-April 2011) than those in the first epidemic year (May 2009-April 2010) (P<0.05), but similar to those of seasonal influenza (P>0.05). Similar to seasonal influenza, pre-existing chronic pulmonary diseases was a risk factor associated with fatal cases of pH1N1 influenza. Different from seasonal influenza, which occurred in spring/summer seasons annually, pH1N1 influenza mainly occurred in autumn/winter seasons in the first epidemic year, but prolonged to winter/spring season in the second epidemic year. The information suggests a tendency that the epidemics of pH1N1 influenza may probably further shift to spring/summer seasons and become a predominant subtype of seasonal influenza in coming years in Guangzhou, China

Integrative Clinical and Genomic Characterization of MTAP-deficient Metastatic Urothelial Cancer

Deficiency of MTAP (MTAPdef) mainly occurs because of homozygous loss of chromosome 9p21, which is the most common copy-number loss in metastatic urothelial cancer (mUC). We characterized the clinical and genomic features of MTAPdef mUC in 193 patients treated at MD Anderson Cancer Center (MDACC) and 298 patients from the phase 2 IMvigor210 trial, which investigated atezolizumab in cisplatin-ineligible and platinum-refractory disease. In the MDACC cohort, visceral metastases were significantly more common for MTAPdef (n = 48) than for MTAP-proficient (MTAPprof; n = 145) patients (75% vs 55.2%; p = 0.02). MTAPdef was associated with poor prognosis (median overall survival [mOS] 12.3 vs 20.2 mo; p = 0.007) with an adjusted hazard ratio of 1.93 (95% confidence interval 1.35–2.98). Similarly, IMvigor210 patients with MTAPlo (n = 29) had a higher incidence of visceral metastases than those with MTAPhi tumors (n = 269; 86.2% vs 72.5%; p = 0.021) and worse prognosis (mOS 8.0 vs 11.3 mo; p = 0.042). Hyperplasia-associated genes were more frequently mutated in MTAPdef tumors (FGFR3: 31% vs 8%; PI3KCA: 31% vs 19%), while alterations in dysplasia-associated genes were less common in MTAPdef tumors (TP53: 41% vs 67%; RB1: 0% vs 16%). Our findings support a distinct biology in MTAPdef mUC that is associated with early visceral disease and worse prognosis

A Measurement of Psi(2S) Resonance Parameters

Cross sections for e+e- to hadons, pi+pi- J/Psi, and mu+mu- have been measured in the vicinity of the Psi(2S) resonance using the BESII detector operated at the BEPC. The Psi(2S) total width; partial widths to hadrons, pi+pi- J/Psi, muons; and corresponding branching fractions have been determined to be Gamma(total)= (264+-27) keV; Gamma(hadron)= (258+-26) keV, Gamma(mu)= (2.44+-0.21) keV, and Gamma(pi+pi- J/Psi)= (85+-8.7) keV; and Br(hadron)= (97.79+-0.15)%, Br(pi+pi- J/Psi)= (32+-1.4)%, Br(mu)= (0.93+-0.08)%, respectively.Comment: 8 pages, 6 figure

Measurements of the Mass and Full-Width of the ηc\eta_c Meson

In a sample of 58 million $J/\psi$ events collected with the BES II detector, the process J/$\psi\to\gamma\eta_c$ is observed in five different decay channels: $\gamma K^+K^-\pi^+\pi^-$, $\gamma\pi^+\pi^-\pi^+\pi^-$, $\gamma K^\pm K^0_S \pi^\mp$ (with $K^0_S\to\pi^+\pi^-$), $\gamma \phi\phi$ (with $\phi\to K^+K^-$) and $\gamma p\bar{p}$. From a combined fit of all five channels, we determine the mass and full-width of $\eta_c$ to be $m_{\eta_c}=2977.5\pm1.0 ({stat.})\pm1.2 ({syst.})$ MeV/$c^2$ and $\Gamma_{\eta_c} = 17.0\pm3.7 ({stat.})\pm7.4 ({syst.})$ MeV/$c^2$.Comment: 9 pages, 2 figures and 4 table.

Observation of a near-threshold enhancement in th p pbar mass spectrum from radiative J/psi-->gamma p pbar decays

We observe a narrow enhancement near 2mp in the invariant mass spectrum of ppbar pairs from radiative J/psi-->gamma ppbar decays. The enhancement can be fit with either an S- or P-wave Breit Wigner fuction. In the case of the S-wave fit, the peak mass is below the 2mp threshold and the full width is less than 30 MeV. These mass and width values are not consistent with the properties of any known meson resonance.Comment: 5 pages, 4 figures, submitted to Phys. Rev. Let
