Institutional Knowledge at Singapore Management University Institutional Knowledge at Singapore Management University Mining social ties beyond homophily Mining social ties beyond homophily

—Summarizing patterns of connections or social ties in a social network, in terms of attributes information on nodes and edges, holds a key to the understanding of how the actors interact and form relationships. We formalize this problem as mining top- k group relationships (GRs) , which captures strong social ties between groups of actors. While existing works focus on patterns that follow from the well known homophily principle, we are interested in social ties that do not follow from homophily, thus, provide new insights. Finding top- k GRs faces new chal- lenges: it requires a novel ranking metric because traditional metrics favor patterns that are expected from the homophily principle; it requires an innovative search strategy since there is no obvious anti-monotonicity for such GRs; it requires a novel data structure to avoid data explosion caused by multidimensional nodes and edges and many-to-many relationships in a social network. We address these issues through presenting an efﬁcient algorithm, GRMiner, for mining top- k GRs and we evaluate its effectiveness and efﬁciency using real data.

Hardware implementation of a strong pseudorandom number generator based block‐cipher system for color image encryption and decryption

This paper proposed a hardware architecture of a strong block‐cipher system dedicated to digital image encryption and decryption. On the one hand, a pseudorandom number generator (PRNG) based on two 3D chaotic systems is created to produce strong keys. On the other hand, a robust algorithm is proposed to ensure high‐level security and low computational complexity of image encryption. The algorithm performs image encryption mainly through three processes: pixel values hiding by applying the XOR operation with a key, pixel positions hiding by operating random permutation, and pixel substitution using the S‐box method. To increase the complexity, R rounds of encryption could be accomplished in a loop. Then as a final step, using the Xilinx Vivado/system generator tool, the hardware cryptosystem is developed, implemented, and evaluated on an FPGA‐Zynq evaluation board. According to the synthesis results, the suggested hardware system performs on a reduced FPGA area and gives a good frequency of 156.813 MHz with a high throughput of 20,072.064 Mbps. Several tools and tests utilizing various images are used to evaluate and analyze the hardware cryptosystem. The experimental results show that the hardware implementation has higher performance compared to other recent works.

Wideband Directional Coupler for Millimeter Wave Application based on Substrate Integrated Waveguide

Recently, Substrate Integrated Waveguide (SIW) techniques have been noticed for millimeter wave devices in microwave applications. In this paper, we are developing a wide band directional 3 dB coupler with a phase of 90 phase delay in the range of 30-40 GHz based on periodic vias and multi hole structure. For achieving this wide bandwidth multi-section coupler is designed based on the theoretical modeling and the simulation result is compared with HFSS and CST with two different numerical methods show good performance with low insertion and return loss, broad operational bandwidth and high isolation. A fractional bandwidth is about 28.5 %.
Stress Heterogeneity and the Onset of Faulting Along Geometrically Irregular Faults

We present a two‐dimensional analytical solution for the static stress field around a rough interlocked interface under background stresses and its applications to faulting. The solution is derived using perturbation theory for the defined interface topography and background stresses. The failure‐ratio, which scales the likelihood to failure of the bulk material around the interface, is calculated adopting the Coulomb failure criterion. We compare model predictions with results of experiments performed on rough rock interfaces and find good agreement between the locations of off‐fault deformation zones and calculated high failure‐ratio values. We further study the effect of fault topography on stress distribution and failure around the San Andreas Fault and find a moderate correlation between Failure‐Ratio values and off‐fault seismic events. We conclude that our model is able to delineate off‐fault regions that are relatively prone to bulk failure due to local effects of fault topography.
A FIXED POINT APPROACH TO THE INTUITIONISTIC FUZZY STABILITY OF QUINTIC AND SEXTIC FUNCTIONAL EQUATIONS

The xed point alternative methods are implemented to give Hyers- Ulam stability for the quintic functional equation f(x + 3y) 5f(x + 2y) + 10f(x+y) 10f(x)+5f(x y) f(x 2y) = 120f(y) and the sextic functional equation f(x + 3y) 6f(x + 2y) + 15f(x +y) 20f(x) + 15f(x y) 6f(x 2y) +f(x 3y) = 720f(y) in the setting of intuitionistic fuzzy normed spaces (IFN-spaces). This method introduces a metrical context and shows that the stability is related to some xed point of a suitable operator. Furthermore, the interdisciplinary relation among the fuzzy set theory, the theory of intu- itionistic spaces and the theory of functional equations are also presented in the paper.
Compact food bar improves cardiopulmonary function in men military athletes: A randomized, placebo-controlled, single-blind clinical trial

Background: This study aimed to evaluate the effects of compact food bar (CFB) designed on cardiopulmonary function in men athletes who serve in military service. Materials and Methods: In this randomized, single-blind, controlled clinical trial, 46 men of military staff were arranged into 2 groups and studied for 28 days; one branch used 3 packs daily, 700 kcal each, of CFB with Functional compounds (Caffeine and L-arginine) and the other group used regular food during training course. Maximal oxygen uptake (VO2 Max) in vitro with cardiopulmonary exercise test, body composition, and physical activity were assessed and recorded at baseline and end of the study period. Results: VO2 Max (P = 0.05) significantly increased in CFB group compared with baseline. Moreover, VO2 Max (P = 0.01), VO2/HR (P = 0.04), oxygen uptake/heart rate (VO2/HR) (P = 0.03), and ventilation per minute/oxygen uptake (VE/VO2) (P = 0.03) significantly increased in CFB group compared with control group. In comparison, there was no significant difference in mean ventilation per minute/carbon dioxide production (VE/VCO2) (P = 0.41), ventilation per minute (VE) (P = 0.69), and breathing frequency (P = 0.056). No significant effect of CFB was found on weight, body mass index (P = 0.23), lean body mass (P = 0.91), and body fat mass (P = 0.91). Conclusion: Our results show that intervention with CFB is more effective than regular diet in improving cardiopulmonary function in men athletes who serve in military service.

Cybersecurity at the Grassroots: American Local Governments and the Challenges of Internet Security

Abstract In this paper, we examine cybersecurity challenges faced by America’s local, governments, including: the extent of cyberattacks; problems faced in preventing attacks from being successful; barriers to providing high levels of cybersecurity management; and actions that local governments believe should be taken to improve cybersecurity practice. Our research method consisted of a focus group of information technology (IT) and cybersecurity officials from one American state. Our findings indicate that cyberattacks are constant and can number in the tens of thousands or more per day. While our participants noted that while they were not perfect at it, they felt that they had cybersecurity technology under good control. Their biggest challenge is human – that is, end-users who make mistakes or engage in misconduct. Local governments face several barriers in providing high levels of cybersecurity, including: insufficient funding and staffing; problems of governance; and insufficient or under-enforced cybersecurity policies. Participants suggested several ways to improve local government cybersecurity, including: vulnerability assessment, scanning and testing, cybersecurity insurance, improving end-user authentication and authorization, end-user training and control, control over the use of external devices, and improved governance methods, among others. We conclude by making suggestions for further research into local government cybersecurity.
Decoherence and entanglement in tripartite systems: Cavity QED

We propose an experimental setup, feasible with present day technology, involving two highquality- factor cavities, one Ramsey zone and a two-level atom which interacts with them. The dynamics in the cavities is modeled by a dissipative dispersive Jaynes-Cummings model. Analytical expresions for the evolution superoperator in each part of the proposed setup and for the concurrence between the atom and the first cavity are given, and the pairwise entanglement of the subsystems is calculated numerically. We consider initial separable states given by the tensor product of a superposition of the two atomic relevant states and coherent states for the fields. We show that for realistic model parameters (including dissipation), when the dissipation rates are smaller than the dispersive frequencies (the ratio between the squared vacuum Rabi frequencies and the detunings), the final state of the cavity fields remains entangled.
Assessment of Effective Coverage of Antenatal Care and Associated Factors in Squatter Settlements of Islamabad Capital Territory, Pakistan: An Analytical Cross-Sectional Study

Background: Effective coverage of antenatal care (ANC) goes beyond contact coverage and assesses the quality of service provided. We used World Health Organization’s recommended positive pregnancy guidelines to assess effective coverage and factors associated with the utilization of ANC among women in squatter settlements of Islamabad Capital Territory. Methods:We conducted a household survey in the study area with 416 women who had given birth in the past one year. Face-to-face interviews were conducted after the selection of study subjects was done through a systematic random sampling approach. Statistical analysis was carried out using Statistical Package for the Social Sciences 22 (SPSS 22; IBM corp. Armonk, NY). Effective ANC coverage was defined as four or more ANC visits along with all WHO-recommended interventions received at least once during ANC. Adjusted odds ratios (adjOR) with 95% CI were calculated using binary logistic regression to determine the independent effects of all associated factors on the outcome. Results: Of the 416 women interviewed, 399 (95.6%) had availed ANC services at least once. The coverage of 4+ ANC visits was 92% but effective coverage was only received by 35% women. The proportion of women who received nutritional interventions, maternal and fetal assessment and other preventive measures was 68%, 51% and 80.8% respectively. Maternal education (adjOR, 95% CI = 4.8[2.4-9.3]), family income (2.3[1.1-5.1]), multiparity (1.7[1.1-2.9]), place of first ANC visit (4.2[1.7-10.5]) and distance from a health facility (2.2[1.3-3.6]) were independently associated with the non-utilization of effective ANC. Conclusion: Despite a very high crude coverage of ANC services, the study shows a very low proportion of women receiving effective coverage. This stresses the importance of measuring the proportion of the population that receives health services with quality to monitor progress toward achieving universal health coverage.
3+1 Orthogonal and Conformal Decomposition of the Einstein Equation and the ADM Formalism for General Relativity

In this work, two particular orthogonal and conformal decompositions of the 3+1 dimensional Einstein equation and Arnowitt-Deser-Misner (ADM) formalism for general relativity are obtained. In order to do these, the 3+1 foliation of the four-dimensional spacetime, the fundamental conformal transformations and the Hamiltonian form of general relativity that leads to the ADM formalism, defined for the conserved quantities of the hypersurfaces of the globally-hyperbolic asymptotically flat spacetimes, are reconstructed. All the calculations up to chapter 7 are just a review. We propose a method in chapter 7 which gives an interesting relation between the Cotton (Conformal) soliton and the static vacuum solutions. The formulation that we introduce can be extended to find the gradient Cotton soliton and the solutions of Topologically Massive Gravity (TMG) as well as the gradient Ricci soliton.
Disseminated Gonococcal Infection: An Unusual Presentation Resembling a Lupus Flare

We present a misdiagnosed case of disseminated gonococcal infection (DGI) in a patient with pre-existing systemic lupus erythematosus (SLE), complaining of sudden onset polyarthralgia and tenosynovitis. Neisseria gonorrhoeae is a common sexually transmitted disease. It can present in young adults as cervicitis and urethritis but is often asymptomatic. In rare instances, gonorrhea can advance to DGI with symptoms such as tenosynovitis, dermatitis, and polyarthralgias, seen most commonly in the knees, ankles, elbows, fingers, and toes. Once suspected, DGI is definitively diagnosed with blood cultures or synovial fluid analysis. SLE is associated with an increased risk of disseminated infections, including DGI. Therefore, early diagnosis of DGI is critical for successful treatment and recovery. Providers should therefore be conscientious of the overlap in symptoms between DGI and a lupus flare. The purpose of examining this case is to encourage the inclusion of disseminated N. gonorrhoeae infection as a differential diagnosis in SLE patients presenting with acute arthralgias regardless of genitourinary symptoms.
Research on the Connotation, Influencing Factors and Promotion Strategy of Automobile Brand Premium

With automobile sales, market share also tends to stabilize. The growth rate of automobile sales is gradually decreasing. At the same time, the goal of maintaining high profits for automobile manufacturers is difficult to achieve only by "car production. " As a component of brand equity, a brand premium has become essential for automobile manufacturers to improve profitability—the direction of development. Currently, the connotation and influencing factors of brand premium are still controversial in academic circles, and there are few particular kinds of research on brand premium in the automobile sales market. This paper takes the automobile industry as the research object and profoundly explores the concept and influencing factors of brand premium. On this basis, it proposes targeted suggestions for automobile manufacturers to improve their brand premium capabilities to encourage Chinese automobile manufacturers to achieve faster transformation and upgrading of industrial structure.
Realization of an isolated Dirac node and strongly modulated Spin Texture in the topological insulator Bi2Te3

The development of spin-based applications of topological insulators requires the knowledge and understanding of spin texture configuration maps as they change via gating in the vicinity of an isolated Dirac node. An isolated (graphene-like) Dirac node, however, does not exist in Bi2Te3. While the isolation of surface states via transport channels has been promisingly achieved in Bi2Te3, it is not known how spin textures modulate while gating the surface. Another drawback of Bi2Te3 is that it features multiple band crossings while chemical potential is placed near the Dirac node (at least 3 not one as in Bi2Se3 and many other topological insulators) and its buried Dirac point is not experimentally accessible for the next generation of experiments which require tuning the chemical potential near an isolated (graphene-like) Dirac node. Here, we image the spin texture of Bi2Te3 and suggest a simple modification to realize a much sought out isolated Dirac node regime critical for almost all potential applications (of topological nature) of Bi2Te3. Finally, we demonstrate carrier control in magnetically and nonmagnetically doped Bi2Te3 essential for realizing giant magneto-optical effects and dissipationless spin current devices involving a Bi2Te3-based platform.
Review of E-Learning Tools in Education

There is great number of e-learning tools available to support teaching and learning in different kinds of educational institutions and vocational study centers. These tools are available to support and provide easy, affordable and convenient means of learning to different students of varying categories in different environment. Considering the economic and personal benefits of e-learning tool, there is still a great number of problems and challenges facing the implementation of elearning in different institutions and the implementers of e-learning facility should appreciate the general and peculiar problems of adopting a suitable e-learning tool with a view to minimizing if not eliminating the problems and challenges. The paper reviewed some e-learning tools with a view to identifying advantages and disadvantages of each of the selected tools and the authors view on each was provided to guide the current and prospective users of elearning tools. Suggestions and recommendations were made to guide the school administrators, e-learning users, policy makers and regulators in order to effectively achieve the efficient and effective use of the tools for desired learning outcome.
Māori values in geothermal management and development

When Māori arrived at Aotearoa (New Zealand), they enjoyed an exclusive relationship with their country’s geothermal resources, which they valued spiritually and physically. After European settlement, this relationship was no longer exclusive, and Māori thereafter held spiritual, physical, and additionally, political values towards geothermal resources in their attempt to remain relevant in Aotearoa’s geothermal industry. In recent history, these values have been overlooked and forgotten by many, including some Māori, due to a certain ignorance displayed by those who practised modern and more invasive forms of geothermal management and development. The presented study involved a series of wānanga (Māori-based workshops), first to discuss the history regarding these values and thereby recognising where they originated from, and second to reinterpret these values as indicators of cultural sustainability, such that they may be more practically accounted for when considering the management and development of geothermal resources in Aotearoa.
