The impact of business analytics on supply chain performance

a r t i c l e i n f o Keywords: Supply chain management Analytical capabilities Information systems Business process management Performance SCOR The paper investigates the relationship between analytical capabilities in the plan, source, make and deliver area of the supply chain and its performance using information system support and business process orientation as moderators. Structural equation modeling employs a sample of 310 companies from different industries from the USA, Europe, Canada, Brazil and China. The findings suggest the existence of a statistically significant relationship between analytical capabilities and performance. The moderation effect of information systems support is considerably stronger than the effect of business process orientation. The results provide a better understanding of the areas where the impact of business analytics may be the strongest. In the modern world competition is no longer between organizations , but among supply chains ('SCs'). Effective supply chain management ('SCM') has therefore become a potentially valuable way of securing a competitive advantage and improving organizational performance [47,79]. However, the understanding of the why and how SCM affects firm performance, which areas are especially important and which are the important moderator effects is still incomplete. This paper thus analyses the impact of business analytics ('BA') in a SC on the improvement of SC performance. The topic is important since enhancing the effectiveness and efficiency of SC analytics is a critical component of a chain's ability to achieve its competitive advantage [68]. BA have been identified as an important " tool " for SCM [44] and optimization techniques have become an integral part of organizational business processes [80]. A correct relevant business decision based on bundles of very large volumes of both internal and external data is only possible with BA [68]. It is therefore not surprising that research interest in BA use has been increasing [43]. However, despite certain anecdotic evidence (see for instance the examples given in [19]) or optimistic reports of return-on-investment exceeding 100% (see e.g. [25]) a systematic and structured analysis of the impact of BA use on SC performance has not yet been conducted. Accordingly, the main contribution of our paper is its analysis of the impact of the use of BA in different areas of the SC (based on the Supply Chain Operations Reference ('SCOR') model) on the performance of the chain. Further, the mediating effects of two important constructs, namely information systems ('IS') support and business …
LuI/sub 3/:Ce-a new scintillator for gamma ray spectroscopy

In this paper, we report on a new cerium doped, high atomic number scintillator, LuI/sub 3/:Ce, for gamma ray spectroscopy. Crystals of this material have been grown using Bridgman process. LuI/sub 3/ crystals doped with 0.5 and 5% Ce/sup 3+/ show high light output (/spl sim/50 000 photons/MeV) and fast principal decay constant (23 to 31 ns). The Ce/sup 3+/ emission peaks at 474 nm. Energy resolution of LuI/sub 3/:Ce coupled to photomultiplier tube (PMT) and measured at 662 keV was /spl sim/11% [full-width at half-maximum (FWHM)]. Timing resolution of LuI/sub 3/-PMT and BaF/sub 2/-PMT detectors operating in coincidence mode was measured to be 210 ps (FWHM). Potential applications of this scintillator are discussed.
Evaluating the twin testosterone transfer hypothesis: A review of the empirical evidence

In this paper we review the evidence that fetuses gestated with a male co-twin are masculinized in development, perhaps due to the influence of prenatal androgens: the so-called twin testosterone transfer (TTT) hypothesis. Evidence from studies of behavioral, perceptual, cognitive, morphological and physiological traits in same- and opposite-sex human twins is considered. Apart from two studies reporting increases in aspects of sensation-seeking for females with a male rather than a female co-twin, there is sparse evidence supporting the TTT hypothesis in behavioral studies. Outcomes from studies of perception (in particular otoacoustic emissions) and cognition (in particular vocabulary acquisition and visuo-spatial ability) provide more consistent evidence in support of masculinized performance in twins with a male co-twin compared to twins with a female co-twin. The outcomes favorable to the TTT hypothesis for otoacoustic emissions and visuo-spatial ability are restricted to females. Studies of physiology and morphology (e.g., brain volume, tooth size and 2D:4D ratio) also show some influence of co-twin sex, but again these effects are often restricted to female twins. Because females produce little endogenous testosterone, the effects of gestation with a male co-twin may be more pronounced in females than males. Thus, while uneven, the evidence for the TTT hypothesis is sufficient to warrant further investigation, ideally using large samples of same- and opposite-sex twins, along with control groups of same- and opposite-sex siblings when the characteristics assessed are potentially open to social influences.
Genetic and environmental influences on pro-inflammatory monocytes in bipolar disorder: a twin study.

CONTEXT
A monocyte pro-inflammatory state has previously been reported in bipolar disorder (BD).


OBJECTIVE
To determine the contribution of genetic and environmental influences on the association between monocyte pro-inflammatory state and BD.


DESIGN
A quantitative polymerase chain reaction case-control study of monocytes in bipolar twins. Determination of the influence of additive genetic, common, and unique environmental factors by structural equation modeling (ACE).


SETTING
Dutch academic research center.


PARTICIPANTS
Eighteen monozygotic BD twin pairs, 23 dizygotic BD twin pairs, and 18 monozygotic and 16 dizygotic healthy twin pairs.


MAIN OUTCOME MEASURES
Expression levels of monocytes in the previously reported coherent set of 19 genes (signature) reflecting the pro-inflammatory state.


RESULTS
The familial occurrence of the association between the monocyte pro-inflammatory gene-expression signature and BD found in the within-trait/cross-twin correlations (twin correlations) was due to shared environmental factors (ie, both monozygotic and dizygotic ratios in twin correlations approximated 1; ACE modeling data: 94% [95% confidence interval, 53%-99%] explained by common [shared] environmental factors). Although most individual signature genes followed this pattern, there was a small subcluster of genes in which genetic influences could dominate.


CONCLUSION
The association of the monocyte pro-inflammatory state with BD is primarily the result of a common shared environmental factor.
User profiling and classification for fraud detection in mobile communications networks

The topic of this thesis is fraud detection in mobile communications networks by means of user profiling and classification techniques. The goal is to first identify relevant user groups based on call data and then to assign a user to a relevant group. Fraud may be defined as a dishonest or illegal use of services, with the intention to avoid service charges. Fraud detection is an important application, since network operators lose a relevant portion of their revenue to fraud. Whereas the intentions of the mobile phone users cannot be observed, it is assumed that the intentions are reflected in the call data. The call data is subsequently used in describing behavioral patterns of users. Neural networks and probabilistic models are employed in learning these usage patterns from call data. These models are used either to detect abrupt changes in established usage patterns or to recognize typical usage patterns of fraud. The methods are shown to be effective in detecting fraudulent behavior by empirically testing the methods with data from real mobile communications networks. © All rights reserved.

Self-Tuning Fuzzy PID Controller Design for Aircraft Pitch Control

In this paper self-tuning fuzzy PID controller is developed to improved the performance for a pitch control of aircraft system. The controller is designed based on the dynamic modeling of system begins with a derivation of suitable mathematical model to describe the longitudinal motion of an aircraft. Fuzzy logic is used to tune each parameter of Proportional-integral-derivative (PID) controller by selecting appropriate fuzzy rules through simulation in Matlab and Simulink. Comparative assessment based on time response specifications between conventional PID controller with self-tuning fuzzy PID for an autopilot of longitudinal dynamic in pitch aircraft is investigated and analyzed. Simulation results show that, the performance of a pitch control system has improved significantly using self-tuning fuzzy PID compared to conventional PID controller.

Geometric phases and robotic locomotion

Robotic locomotion is based in a variety of instances upon cyclic changes in the shape of a robot mechanism. Certain variations in shape exploit the constrained nature of a robot's interaction with its environment to generate net motion. This is true for legged robots, snakelike robots, and wheeled mobile robots undertaking maneuvers such as parallel parking. In this paper we explore the use of tools from diierential geometry to model and analyze this class of locomotion mechanisms in a uniied way. In particular, we describe locomotion in terms of the geometric phase associated with a connection on a principal bundle, and address issues such as controllability and choice of gait. We also provide an introduction to the basic mathematical concepts which we require and apply the theory to numerous example systems. 1. Introduction The term \locomotion" refers to autonomous movement from place to place. Robotic locomotion employs a variety of mechanisms. Though most of today's mobile robots have wheels or legs, other classes of robots|such as hyper-redundant, snakelike robots|are becoming increasingly popular. Traditionally, distinct methods of locomotion have been studied separately, and most approaches have relied on the speciic properties of a given system to analyze its locomotive capabilities. Despite their diierences in approach, however, most robotic locomotion systems share certain common features. Many involve motion in either two or three dimensional Euclidean space. Land based robots almost always rely upon interaction with the environment to achieve motion. These robots push, slide, and roll along the ground. A variety of systems, furthermore, rely on periodic control inputs to achieve motion in certain directions. The use of periodic inputs to generate motion is particularly intriguing since it is the rectiication of these inputs which characterizes locomotion. By changing the basic shape of a robot in a cyclic fashion, net motion in some direction can be
Comparing S-100 beta protein levels and neurocognitive functions between patients undergoing on-pump and off-pump coronary artery bypass grafting.

BACKGROUND
In the present study, we aimed to investigate the effects of off-pump coronary artery bypass grafting and on-pump cardiopulmonary bypass on the serum S-100 beta (S-100B) protein levels and neurocognitive functions of the patients.


MATERIALS AND METHODS
Sixty-four patients undergoing coronary artery bypass grafting (CABG) were enrolled in the study and were divided into two groups: off-pump (group I, n = 24) and on-pump CABG (group II, n = 40) group. Serum S-100B levels were measured before and 0, 6, and 24 h after the operation. Neurocognitive function tests were done preoperatively and were repeated in the postoperative period as well.


RESULTS
Serum S-100B levels were similar between the two groups preoperatively. However, median S-100B levels at 0, 6, and 24 h after the surgery were found to be significantly lower in the off-pump CABG group than in the on-pump group. The preoperative neurocognitive functions of the patients were similar between the two groups, whereas neurocognitive function was found to be significantly impaired postoperatively in the on-pump group in comparison with the off-pump CABG group.


CONCLUSION
We concluded that off-pump CABG is associated with decreased serum S100 protein levels and less impairment on neurocognitive functions compared with the on-pump group.
Metabolic Factors , Adipose Tissue , and Plasminogen Activator Inhibitor-1 Levels in Type 2 Diabetes Findings From the Look AHEAD Study

Objective—Plasminogen activator inhibitor-1 (PAI-1) production by adipose tissue is increased in obesity, and its circulating levels are high in type 2 diabetes. PAI-1 increases cardiovascular risk by favoring clot stability, interfering with vascular remodeling, or both. We investigated in obese diabetic persons whether an intensive lifestyle intervention for weight loss (ILI) would decrease PAI-1 levels independently of weight loss and whether PAI-1 reduction would be associated with changes in fibrinogen, an acute phase reactant, or fibrin fragment D-dimer (D-dimer), a marker of ambient coagulation balance. Methods and Results—We examined 1-year changes in PAI-1, D-dimer, and fibrinogen levels; adiposity; fitness; glucose; and lipid control with ILI in 1817 participants from Look AHEAD, a randomized trial investigating the effects of ILI, compared with usual care, on cardiovascular events in overweight or obese diabetic persons. Median PAI-1 levels decreased 29% with ILI and 2.5% with usual care (P 0.0001). Improvements in fitness, glucose control, and high-density lipoprotein cholesterol were associated with decreased PAI-1, independently of weight loss (P 0.03 for fitness, P 0.0001 for others). Fibrinogen and D-dimer remained unchanged. Conclusion—Reductions in PAI-1 levels with ILI in obese diabetic individuals may reflect an improvement in adipose tissue health that could affect cardiovascular risk without changing fibrinogen or D-dimer levels.

The Canadian STOP-PAIN project: the burden of chronic pain-does sex really matter?

OBJECTIVES
The Canadian STOP-PAIN Project assessed the human and economic burden of chronic pain (CP) in individuals on waitlists of Canadian multidisciplinary pain treatment facilities. This article focuses on sex differences. Objectives were to (1) determine the pain characteristics and related biopsychosocial factors that best differentiated women and men with CP; and (2) examine whether public and private costs associated with CP differed according to sex.


MATERIALS AND METHODS
Sample consisted of 441 women and 287 men who were evaluated using self-administered questionnaires and a structured interview protocol. A subsample (233 women and 137 men) recorded all pain-related expenditures in a comprehensive diary over 3 months.


RESULTS
Results revealed that the burden of illness associated with CP was comparable in both sexes for average and worst pain intensity, pain impact on daily living, quality of life, and psychological well-being. The same was true for pain-related costs. The results of a hierarchical logistic regression analysis, in which sex was treated as the dependent variable, showed that factors that differentiated men and women were: work status, certain circumstances surrounding pain onset, present pain intensity, intake of particular types of pain medication, use of certain pain management strategies, pain beliefs, and utilization of particular health care resources.


DISCUSSION
This study suggests that women and men who are referred to multidisciplinary pain treatment facilities do not differ significantly in terms of their pain-related experience. However, the aspects that differ may warrant further clinical attention when assessing and managing pain.

A bounded upwinding scheme for computing convection-dominated transport problems

A practical high resolution upwind differencing scheme for the numerical solution of convection-dominated transport problems is presented. The scheme is based on TVD and CBC stability criteria and is implemented in the context of the finite difference methodology. The performance of the scheme is investigated by solving the 1D/2D scalar advection equations, 1D inviscid Burgers’ equation, 1D scalar convection–diffusion equation, 1D/2D compressible Euler’s equations, and 2D incompressible Navier– Stokes equations. The numerical results displayed good agreement with other existing numerical and experimental data. 2012 Elsevier Ltd. All rights reserved.
Duelist Algorithm: An Algorithm Inspired by How Duelist Improve Their Capabilities in a Duel

This paper proposes an optimization algorithm based on how human fight and learn from each duelist. Since this algorithm is based on population, the proposed algorithm starts with an initial set of duelists. The duel is to determine the winner and loser. The loser learns from the winner, while the winner try their new skill or technique that may improve their fighting capabilities. A few duelists with highest fighting capabilities are called as champion. The champion train a new duelists such as their capabilities. The new duelist will join the tournament as a representative of each champion. All duelist are re-evaluated, and the duelists with worst fighting capabilities is eliminated to maintain the amount of duelists. Two optimization problem is applied for the proposed algorithm, together with genetic algorithm, particle swarm optimization and imperialist competitive algorithm. The results show that the proposed algorithm is able to find the better global optimum and faster iteration. Keywords—Optimization; global, algorithm; duelist; fighting
Stress, coping and suicide ideation in Chinese college students.

The study was to examine 1) whether stress and coping styles could significantly predict the probability of suicide ideation; 2) and whether coping styles were mediators or moderators on the association between life stress and suicide ideation. The survey was conducted in a sample of 671 Chinese college students. Approximately twenty percent students reported having suicide ideation. Life stress, active coping styles, and passive coping styles all had independent effect on the probability of suicide ideation. Passive coping styles, especially fantasizing, mediated the relation between life stress and suicide ideation. Moderation hypotheses were not supported. Implications of the findings and future directions were discussed.
Improving personalized web search using result diversification

We present and evaluate methods for diversifying search results to improve personalized web search. A common personalization approach involves reranking the top N search results such that documents likely to be preferred by the user are presented higher. The usefulness of reranking is limited in part by the number and diversity of results considered. We propose three methods to increase the diversity of the top results and evaluate the effectiveness of these methods.
Secure embedded system hardware design - A flexible security and trust enhanced approach

Embedded systems have found a very strong foothold in global Information Technology (IT) market since they can provide very specialized and intricate functionality to a wide range of products. On the other hand, the migration of IT functionality to a plethora of new smart devices (like mobile phones, cars, aviation, game or households machines) has enabled the collection of a considerable number of data that can be characterized sensitive. Therefore, there is a need for protecting that data through IT security means. However, eare usually dployed in hostile environments where they can be easily subject of physical attacks. In this paper, we provide an overview from ES hardware perspective of methods and mechanisms for providing strong security and trust. The various categories of physical attacks on security related embedded systems are presented along with countermeasures to thwart them and the importance of reconfigurable logic flexibility, adaptability and scalability along with trust protection mechanisms is highlighted. We adopt those mechanisms in order to propose a FPGA based embedded system hardware architecture capable of providing security and trust along with physical attack protection using trust zone separation. The benefits of such approach are discussed and a subsystem of the proposed architecture is implemented in FPGA technology as a proof of concept case study. From the performed analysis and implementation, it is concluded that flexibility, security and trust are fully realistic options for embedded system security enhancement. 2013 Elsevier Ltd.
