Research on Influence Maximization Method for Complex Network

The influence maximization (IM) is a key algorithm problem in information dissemination research. it aims to select a set of K users (also called seed sets) from a network and maximize the number of affected users (influence spread) through a specific information dissemination model. However, despite its huge application potential, with the advent of the era of big data, all kinds of networks tend to be complicated, and there is relatively little research on influence maximization of multilayer networks in complex networks, because in these networks, nodes are different types. On the other hand, most of the existing research on influence maximization relies on greedy algorithms and can only obtain a single solution. With that in mind, we focus on the influence maximization problem of multilayer networks in complex networks. specifically, we first define some novel concepts about the process of information dissemination in multilayer networks; then, we construct the influence maximization problem in multilayer networks into a multi-objective optimization problem. Finally, we do a lot of experiments on the real datasets, and the results show that the algorithm in this paper has a large competitive advantage in the influence spread and running time compared with the existing influence maximization algorithm.
TRENDELENBURG TEST AND ACL RISK FACTORS DURING UNANTICIPATED CUTTING MANOEUVRE – A PILOT STUDY

The aim of this study was to find differences between the Trendelenburg test and risk factors for an ACL injury during a cutting manoeuvre in two age groups. Six female athletes divided into two groups (n3x2) participated in this study. Ten infrared cameras and force platform were used to collect the kinematic and kinetic data. The results of this pilot study suggest no hip weakness was observed in either group. The younger group had a larger difference between starting and finishing position during TT. In other side we found the higher values of the ACL risk factors in the older group.
Trials and Errors

On November 30, 2006, executives at Pfizer—the largest pharmaceutical company in the world—held a meeting with investors at the firm’s research center in Groton, Connecticut. Jeff Kindler, then CEO of Pfizer, began the presentation with an upbeat assessment of the company’s efforts to bring new drugs to market. He cited “exciting approaches” to the treatment of Alzheimer’s disease, fibromyalgia, and arthritis. But that news was just a warm-up. Kindler was most excited about a new drug called torcetrapib, which had recently entered Phase III clinical trials, the last step before filing for FDA approval. He confidently declared that torcetrapib would be “one of the most important compounds of our generation. ”
Executive function and its relation to anatomical connectome in homosexual and heterosexual men.

Background Sexual orientation has been suggested to affect executive function, of which the neurobiological basis is still largely unknown. In this study, we explored the interrelationship between neuropsychological characteristics in homosexual and heterosexual men and their anatomical connectome by graph theoretical analysis. Methods Fifty-three homosexual and 47 heterosexual males underwent diffusion tensor magnetic resonance imaging (MRI) and neuropsychological assessments. Whole-brain anatomical networks were constructed using white matter tractography, performed on the diffusion tensor imaging data. Neuropsychological tests included the Wisconsin Card Sorting Test (WCST), the Continuous Performance Test (CPT) and the Trail-Making Test (TMT). Results The cognitive performance of homosexual men was significantly poorer than their heterosexual counterparts in terms of WCST total correct responses. Anatomical connectome analysis revealed a lower (P=0.001) anatomical connectivity between left PoCG and left SMG (P=0.003) in homosexual men as compared to heterosexual men. Linear regression analyses showed that the WCST total correct responses score was significantly linked with sexual orientation (P=0.001). The anatomical connectivity strength between left PoCG and left SMG was also shown to be significantly correlated with sexual orientation (P=0.039) and education (P=0.047). Conclusions Our study demonstrated the differences in the performance of WCST and anatomical connectome of large-scale brain networks between homosexual and heterosexual men, extending our understanding of the brain's circuitry and the characteristics of executive function in men of different sexual orientation.
Atraric Acid Exhibits Anti-Inflammatory Effect in Lipopolysaccharide-Stimulated RAW264.7 Cells and Mouse Models

Lichens, composite organisms resulting from the symbiotic association between the fungi and algae, produce a variety of secondary metabolites that exhibit pharmacological activities. This study aimed to investigate the anti-inflammatory activities of the secondary metabolite atraric acid produced by Heterodermia hypoleuca. The results confirmed that atraric acid could regulate induced pro-inflammatory cytokine, nitric oxide, prostaglandin E2, induced nitric oxide synthase and cyclooxygenase-2 enzyme expression in lipopolysaccharide (LPS)-stimulated RAW264.7 cells. Meanwhile, atraric acid downregulated the expression of phosphorylated IκB, extracellular signal-regulated kinases (ERK) and nuclear factor kappa B (NFκB) signaling pathway to exhibit anti-inflammatory effects in LPS-stimulated RAW264.7 cells. Based on these results, the anti-inflammatory effect of atraric acid during LPS-induced endotoxin shock in a mouse model was confirmed. In the atraric acid treated-group, cytokine production was decreased in the peritoneum and serum, and each organ damaged by LPS-stimulation was recovered. These results indicate that atraric acid has an anti-inflammatory effect, which may be the underlying molecular mechanism involved in the inactivation of the ERK/NFκB signaling pathway, demonstrating its potential therapeutic value for treating inflammatory diseases.
Affirmative Action, Mismatch, and Economic Mobility after California's Proposition 209

Proposition 209 banned race-based affirmative action at California public universities in 1998. This study analyzes Prop 209's impact on student outcomes using a difference-in-difference research design and a newly-constructed longitudinal database linking all 1994-2002 University of California applicants to their college enrollment, course performance, major choice, degree attainment, and wages into their mid-30s. Ending affirmative action caused UC's 10,000 annual underrepresented minority (URM) freshman applicants to cascade into lower-quality public and private universities. URM applicants' undergraduate and graduate degree attainment declined overall and in STEM fields, especially among lower-testing applicants. As a result, the average URM UC applicant's wages declined by 5 percent annually between ages 24 and 34, almost wholly driven by declines among Hispanic applicants. By the mid-2010s, Prop 209 had caused a cumulative decline in the number of early-career URM Californians earning over $100,000 by at least 3 percent. Prop 209 also deterred thousands of qualified URM students from applying to any UC campus. Enrolling at less-selective UC campuses did not improve URM students' performance or persistence in STEM course sequences. Complementary regression discontinuity and institutional value-added analyses suggest that affirmative action's net wage benefits for URM applicants exceed its (potentially small) net costs for on-the-margin white and Asian applicants. These findings are inconsistent with the university "Mismatch Hypothesis" and provide the first causal evidence that banning affirmative action exacerbates socioeconomic inequities.
Central DOA Estimation Method for Exponential-Type Coherent Distributed Source Based on Fourth-Order Cumulant

The performance of direction-of-arrival (DOA) estimation for sparse arrays applied to the distributed source is worse than that applied to the point source model. In this paper, we introduce the coprime array with a large array aperture into the DOA estimation algorithm of the exponential-type coherent distributed source. In particular, we focus on the fourth-order cumulant (FOC) of the received signal which can provide more useful information when the signal is non-Gaussian than when it is Gaussian. The proposed algorithm extends the array aperture by combining the sparsity of array space domain with the fourth-order cumulant characteristics of signals, which improves the estimation accuracy and degree of freedom (DOF). Firstly, the signal-received model of the sparse array is established, and the fourth-order cumulant matrix of the received signal of the sparse array is calculated based on the characteristics of distributed sources, which extend the array aperture. Then, the virtual array is constructed by the sum aggregate of physical array elements, and the position set of its maximum continuous part array element is obtained. Finally, the center DOA estimation of the distributed source is realized by the subspace method. The accuracy and DOF of the proposed algorithm are higher than those of the distributed signal parameter estimator (DSPE) algorithm and least-squares estimation signal parameters via rotational invariance techniques (LS-ESPRIT) algorithm when the array elements are the same. Complexity analysis and numerical simulations are provided to demonstrate the superiority of the proposed method.
Immunotherapy for thymoma

Thymic epithelial tumors (TETs) are rare thymic neoplasms. There are approximately 1.5 cases per million TETs per year. They are the most common anterior mediastinal tumors in adults. Due to limited activity of available treatment options novel strategies and treatment options are needed and treatment with immune checkpoint inhibitors is an attractive option. Thymic epithelial tumors have one of the lowest tumor mutational burden among all cancer in adults, but high expression of PD-L1 on tumor cells and abundant CD8+ lymphocytes provide a strong rational for implementing immune checkpoint inhibitors (ICIs) which target PD-1/PD-L1 pathway in the treatment of TETs. Few small early stage clinical trials were published so far evaluating efficacy of pembrolizumab and avelumab in thymoma and thymic carcinoma patients. Al trials showed reasonable response rates and progression-free survival. Higher PD-L1 expression was predictor of response in all trials. However, increased incidence of immune-related adverse events was seen in TET patients treated with immune checkpoint inhibitors compared to patients with other cancers. At the moment, ICIs are not standard of care for patients with TET and larger trials are needed to establish the right role of ICIs regarding efficacy and safety of these agents.
ACTIVE FAULTS AT STRUCTURE'S FOUNDATIONS:

Different scientific papers as well as the industrial, regional, national and international regulatory documents and guidelines define term “active fault” in different ways, which affects resultant hazard assessment significantly. Most of definitions focus on time span in which fault motions took place in the past, which differs from ~10 000 years (Holocene) to more than 2 million years (Quaternary period). However, engineering, technical approach to study any hazardous natural phenomena requires quantitative assessment of the expected impact. In case of an active fault, such impact depends either on the singleevent displacement value or on the rate of permanent motions, which should be used, among others, as the input parameters for the design of any protection or mitigation measures. The threshold values of these parameters must be included in active fault definition along with the above time span. The definition considering both time interval of the activity manifestation and the ability of structures to sustain these movements was proposed and included in Russian seismic code, which defines active fault as follows: "Fault is considered as being active if there is evidence of permanent or periodical displacements in the Late Pleistocene – Holocene time (during last 100,000 years), with such single-event offset value or displacement rate that poses a threat to the structure and requires special engineering or placement measures to ensure its safety". Such approach implies close cooperation between earth scientists studying active faults on the one hand and engineers designing protection or mitigation measures and project managers assessing risks on the other hand. Such cooperation should start from the beginning, at the site/route selection stage of project implementation, when it is especially important to identify the potentially hazardous phenomena correctly or to be sure that they are absent and could not affect the structure. Active fault parameters necessary for the design such as its desirable location accuracy, details of motion kinematics and the threshold displacement values must be listed in the technical assignment for site investigations provided to the Contractor who will perform the design. It should help avoiding both underand overestimation of fault-related hazards that could cause the significant economic losses. The proposed approach is focused on discrimination of faults that cross construction sites or lifeline routes and could affect the engineering structures directly. Seismic hazard assessment in which causative faults identification also plays a critical role, allows much broader definition of the tectonic structures that can be considered as active and, thus, have the potential to generate large earthquakes.

It provides a fast seamless bidirectional control method to maintain the DC grid voltage, battery voltage and current within predefined limits. In addition, an inner current control loop is not employed, so that the bandwidth of controller can be higher compared with the PI controller.
Hybrid Transformer Based High Boost Ratio DC-DC Converter for Photovoltaic Applications

Now-a-days due to the shortage of electric power and rising cost of non-renewable energy resources generating electric power from the renewable energy resources such as PV modules are increasing day to day. This paper presents non-isolated, high step-up dc-dc converter with hybrid transformer with for low voltage renewable energy resources applications. The proposed converter utilizes hybrid transformer to transfer the inductive and capacitive energy simultaneously, achieving high step-up voltage with smaller sized magnetic component, the turnoff loss of switch is minimized, increasing the efficiency of the converter under all load conditions. By changing the input voltage the voltage stresses on the active switch and diodes are maintained at low level and are independent as a result of the resonant capacitor transferring energy to the output of the converter. Due to high system efficiency as well as ability to operate with a wide variable input voltage, the proposed dc-dc converter is an attractive design for alternative low dc voltage energy sources, such as solar PV modules and fuel cells.
High-Gain SIR Dual-Band Antenna Based on CSRR-Enhanced SIW for 2.4/5.2/5.8 GHz WLAN

This paper presents a dual-band step impedance resonator (SIR) antenna based on metamaterial-inspired periodic structure of coupled complementary split-ring resonators substrate-integrated waveguide (CSRR-SIW). The antenna supports wireless local area networks (WLAN) bands at 2.4/5.2/5.8 GHz. The CSRRs and two branches of the SIR element are etched on the top and bottom metal surfaces of the substrate. The SIR element produces a fundamental frequency f1 at 2.4 GHz and a second harmonic frequency fs2 at 5.7 GHz. Meanwhile, the CSRRs produces a resonant frequency at high-frequency band around 5.2 GHz, which can be combined with the second harmonic frequency fs2 at 5.7 GHz. The high-frequency bandwidth can then be broadened. The simulated and measured results show that the dual operation bands with bandwidths of 16% from 2.25 GHz to 2.64 GHz and 18.2% from 5 GHz to 6 GHz for |S11| < −10 dB are achieved. Meanwhile, the proposed antenna has peak gains ranging from 6.5 dBi to 7 dBi and from 7 dBi to 7.7 dBi in the lower and upper bands, respectively. Compared with many previously reported dual-band antenna designs, the proposed antenna achieves comparable bandwidth performance and larger gain per unit area with a relatively smaller size. Moreover, the simple structure renders the proposed antenna has the advantage of easy-processable and cost-effective implementation.
Direct proportionality of acetylation of microtubules in sperm tails to their adhesivity.

The hypothesis for this experiment is that the degree of acetylation of microtubules in sperm tails is directly proportional to their adhesivity for each other. The immunofluorescent staining done in this experiment affected the DNA, tubulin, and acetylated tubulin in sea urchin sperm and egg, gastrulas, blastulas, and a zygote in first mitosis. The experiment’s hypothesis is concerned with the staining results from the tails of the sea urchin sperm.
Association Between Concentration of Organic Nutrients in the Grain, Endosperm Cell Number and Grain Dry Weight Within the Ear of Wheat

The present investigation was conducted to examine the association between the concentrations of sugars and amino acids in the grain, cell number in the endosperm and final dry weights of grains at various positions within the ear of wheat. Variation in the grain weight within a spikelet or between spikelets was dependent upon the number of cells formed in the endosperm. Concentrations of assimilates measured in the grain, however, showed either no relationship or an inverse relationship with the endosperm cell numbers. Variation in cell number in the endosperm between spikelets inserted at different positions on the rachis was not related to the carbohydrate concentration in the sections of rachis bearing the respective spikelets.
The Sex Ratio of Orange-flanked Bush-robins (Aves: Passeriformes: Muscicapidae) from a Winter Population in Central China

ABSTRACT The sex ratio of a population is an important demographic parameter, but compared with breeding populations, the sex ratios of avian winter populations have received relatively little attention. The orange-flanked bush-robin (Tarsiger cyanurus) is a migratory species whose plumage is sexually dimorphic with delayed plumage maturation wherein first-year males show female-like plumage. We investigated the sex ratio of an orange-flanked bush-robin population wintering in Dongzhai National Nature Reserve located in central China. The results show that most (> 85%) orange-flanked bush-robins of this population have female-like plumage, implying that the population sex ratio might be female-biased. However, genetic analysis revealed that most (c. 70%) individuals with female-like plumage were males, resulting in a significantly male-biased population sex ratio. Among the individuals with female-like plumage, the males were found to have significantly longer wings and tails than females, but the accuracy of a discriminant analysis employing the two morphological traits to sex them was low. The results suggest that a genetic method is a more appropriate way to sex those orange-flanked bush-robins with female-like plumage and more importantly, one needs to be cautious when using the morphology of individuals to infer the sex ratio of a population for species like orange-flanked bush-robins.
Amplification behavior of vertical motion observed from downhole arrays

Recently, very strong vertical ground motions have been recorded during several earthquakes and have been considered to be critical to structure designs. Similar to horizontal motions, vertical motions can be amplified with the local site condition. However, the amplification behavior of vertical motion is different from that of horizontal motion because of different propagation mechanisms. In this study, three component records of five downhole arrays, including different geological conditions, ground water tables, and intensity of motions, were analyzed to evaluate the differences of wave propagation in the vertical and horizontal directions. The amplification behaviors of two directions are characterized by the transfer function of the surface and downhole measurement. The findings are as follows: (1) the amplification of vertical motion is less significant than that of horizontal motion, (2) the amplification behavior of vertical motion is less dependent on the intensity of motion (i.e., soil nonlinearity) than that of horizontal motion, and (3) the amplification behavior of vertical motion is more sensitive to the location of ground water table than that of horizontal motion. These variances should be considered in the dynamic site response analysis.

One-Time and Interactive Aggregate Signatures from Lattices

An aggregate signature scheme enables one to aggregate multiple signatures generated by diﬀerent people on diﬀerent messages into a short aggregate signature. We construct two signature aggregation schemes whose security is based on the standard SIS problem on lattices in the random oracle model. Our ﬁrst scheme supports public aggregation of signatures, but for a one-time signature scheme. Our second scheme supports aggregation of signatures in a many-time signature scheme, but the aggregation process requires interaction among the signers. In both schemes, the size of the aggregate signature is at most logarithmic in the number of signatures being aggregated
