Achieving High Robustness in Supply Distribution Networks by Rewiring

In this paper, we propose a new rewiring approach for distribution networks called randomized local rewiring (RLR). We evaluate the robustness of original and rewired distribution networks using new metrics and show that the choice of a network topology can affect its robustness considerably. Some supply and distribution networks exhibit characteristics similar to those of scale-free networks. Simulation results show that applying RLR to such distribution networks can improve the network robustness on the supply availability and network connectivity metrics when both random and targeted disruptions are likely to occur. A unique feature of our model is a tunable rewiring parameter, which makes it possible to design networks with the same performance on the supply availability, network connectivity, and average delivery efficiency metrics in the presence of both types of disruptions. This paper will describe the robustness metrics and the new approach, illustrate the experimental results in the context of a military logistic and a retailer's distribution network, and discuss the insights gained about choosing the right topology for achieving higher robustness.
Forecasting Private Consumption : Survey-based Indicators vs

In this study we introduce a new indicator for private consumption based on search query time series provided by Google Trends. The indicator is based on factors extracted from consumption-related search categories of the Google Trends application Insights for Search. The forecasting performance of the new indicator is assessed relative to the two most common survey-based indicators the University of Michigan Consumer Sentiment Index and the Conference Board Consumer Confi dence Index. The results show that in almost all conducted in-sample and out-of-sample forecasting experiments the Google indicator outperforms the survey-based indicators. This suggests that incorporating information from Google Trends may off er signifi cant benefi ts to forecasters of private consumption. JEL Classifi cation: C53, E21, E27
Broadband Circularly Polarized Antenna With L-shaped Strip Feeding and Shorting-Pin Loading

A patch antenna with simple feeding structure for broadband circular polarization is proposed in this letter. The patch is first designed with horizontal L-shaped strip (HLS) feeding, which feeds the radiation patch at orthogonal orientations with 90° phase difference. Two minimum points can be seen in the axial-ratio (AR) curve. By loading a shorting pin to the patch, the minimum point of lower frequency moves to higher frequency, and wide AR band is obtained consequently. Measured results show that 10-dB return-loss bandwidth of 23.6% (2.09-2.65 GHz), 3-dB AR bandwidth of 17.9% (2.18-2.61 GHz), and average gain of 8.5 dBic across the operating band are achieved for the proposed antenna with a low profile of 0.09λ0 ( λ0 is the wavelength in free space corresponding to 2.4 GHz).
Real-time robust human tracking based on Lucas-Kanade optical flow and deep detection for embedded surveillance

Object tracking is one of the most important functions in surveillance systems, especially in the system with Pan/Tilt/Zoom Camera. In this paper, we propose a real-time robust human tracking method for embedded surveillance. The proposed human tracking method tracks human objects based on Lucas-Kanade (LK) optical flow algorithm [1], rectifies tracking error due to accumulation or object missing by readjusting tracked human object bounding boxes periodically. Human localization information is obtained from a reliable deep learning-based human. It also handles occlusion by combination of LK information and human detector information. In order to achieve fast and robust processing, computationally light but reliable human detector is developed based on YOLOv2 object detector [2] model. Through experiments in comparison with other state-of-the-art tracking methods, it is shown that the proposed human tracking method operates fast and reliably with occlusion handling, and that performs better than or comparable to others.
Ingested protein dose response of muscle and albumin protein synthesis after resistance exercise in young men.

BACKGROUND
The anabolic effect of resistance exercise is enhanced by the provision of dietary protein.


OBJECTIVES
We aimed to determine the ingested protein dose response of muscle (MPS) and albumin protein synthesis (APS) after resistance exercise. In addition, we measured the phosphorylation of candidate signaling proteins thought to regulate acute changes in MPS.


DESIGN
Six healthy young men reported to the laboratory on 5 separate occasions to perform an intense bout of leg-based resistance exercise. After exercise, participants consumed, in a randomized order, drinks containing 0, 5, 10, 20, or 40 g whole egg protein. Protein synthesis and whole-body leucine oxidation were measured over 4 h after exercise by a primed constant infusion of [1-(13)C]leucine.


RESULTS
MPS displayed a dose response to dietary protein ingestion and was maximally stimulated at 20 g. The phosphorylation of ribosomal protein S6 kinase (Thr(389)), ribosomal protein S6 (Ser(240/244)), and the epsilon-subunit of eukaryotic initiation factor 2B (Ser(539)) were unaffected by protein ingestion. APS increased in a dose-dependent manner and also reached a plateau at 20 g ingested protein. Leucine oxidation was significantly increased after 20 and 40 g protein were ingested.


CONCLUSIONS
Ingestion of 20 g intact protein is sufficient to maximally stimulate MPS and APS after resistance exercise. Phosphorylation of candidate signaling proteins was not enhanced with any dose of protein ingested, which suggested that the stimulation of MPS after resistance exercise may be related to amino acid availability. Finally, dietary protein consumed after exercise in excess of the rate at which it can be incorporated into tissue protein stimulates irreversible oxidation.
Incidence and clinical impact of dual nonresponsiveness to aspirin and clopidogrel in patients with drug-eluting stents.

OBJECTIVES
This study sought to determine the incidence of aspirin nonresponsiveness in addition to clopidogrel nonresponsiveness and whether this association identifies patients at an increased risk of drug-eluting stent (DES) thrombosis.


BACKGROUND
Nonresponsiveness to clopidogrel is a predictor of DES thrombosis. No prospective data exist about the possible association of dual nonresponsiveness to clopidogrel and aspirin with DES thrombosis.


METHODS
Platelet function was assessed after a loading dose of 600 mg clopidogrel in 746 patients who had successful DES implantation followed by 6-month dual-antiplatelet therapy. Platelet reactivity was assessed by light transmittance aggregometry using adenosine 5'-diphosphate, arachidonic acid, and collagen. The primary end point was definite/probable DES thrombosis at 6 months. The secondary end point was the composite of cardiac mortality and DES thrombosis.


RESULTS
The incidence of dual nonresponsiveness to aspirin and clopidogrel was 6%. Definite/probable DES thrombosis was significantly higher in dual aspirin and clopidogrel nonresponders (11.1%) than in clopidogrel and aspirin responders (2.1%, p < 0.001), isolated clopidogrel nonresponders (2.2%, p < 0.05), or aspirin nonresponders (2.3%, p < 0.05). The incidence of the secondary end point was 4.4% in isolated clopidogrel nonresponders, 2.3% in isolated aspirin nonresponders, and 13.3% in dual aspirin and clopidogrel nonresponders. Dual clopidogrel and aspirin nonresponsiveness was an independent predictor of DES thrombosis (hazard ratio: 3.18, 95% confidence interval: 1.14 to 8.83, p = 0.027) and the composite of cardiac mortality and DES thrombosis (hazard ratio: 2.94, 95% confidence interval: 1.16 to 7.41, p = 0.022).


CONCLUSIONS
Dual nonresponsiveness to aspirin and clopidogrel is a relatively infrequent condition that identifies patients at a very high risk of DES thrombosis or death.
Deep Residual Learning and PDEs on Manifold

In this paper, we formulate the deep residual network (ResNet) as a control problem of transport equation. In ResNet, the transport equation is solved along the characteristics. Based on this observation, deep neural network is closely related to the control problem of PDEs on manifold. We propose several models based on transport equation, Hamilton-Jacobi equation and Fokker-Planck equation. The discretization of these PDEs on point cloud is also discussed. keywords: Deep residual network; control problem; manifold learning; point cloud; transport equation; Hamilton-Jacobi equation 1 Deep Residual Network Deep convolution neural networks have achieved great successes in image classification. Recently, an approach of deep residual learning is proposed to tackle the degradation in the classical deep neural network [7, 8]. The deep residual network can be realized by adding shortcut connections in the classical CNN. A building block is shown in Fig. 1. Formally, a building block is defined as: y = F (x, {Wi}) + x. Here x and y are the input and output vectors of the layers. The function F (x, {Wi}) represents the residual mapping to be learned. In Fig. 1, F = W2 · σ(W1 · σ(x)) in which σ = ReLU ◦ BN denotes composition of ReLU and Batch-Normalization. ∗Department of Mathematics, Hong Kong University of Science & Technology, Hong Kong.

Treatment of Fordyce spots with CO2 laser.

BACKGROUND
Fordyce spots are heterotopic sebaceous glands that can be located at the lips' vermilion or the oral mucosa. Although this is considered a rather common disorder, a treatment for this condition that sometimes affects patients from only a cosmetic viewpoint has not yet been described.


OBJECTIVE
To evaluate CO2 superpulsed laser treatment in two subjects with Fordyce spots.


METHODS
Two patients with papules and yellowish plaques at the upper lip corresponding to Fordyce spots were treated with coherent Ambulase CO2 superpulsed laser (Coherent Medical, Palo Alto, CA); after informed consent was obtained, two to three passes were performed in one session using 2 and 4 W and a spot size of 2 mm.


RESULTS
Complete re-epithelization was observed 2 weeks later with no residual Fordyce papules in the treated area and no side effects.


CONCLUSION
Our findings suggest that CO2 superpulsed laser can be considered a safe and effective treatment for patients with Fordyce spots, offering excellent cosmetic results.
Hidden Markov model for human to computer interaction: a study on human hand gesture recognition

Human hand recognition plays an important role in a wide range of applications ranging from sign language translators, gesture recognition, augmented reality, surveillance and medical image processing to various Human Computer Interaction (HCI) domains. Human hand is a complex articulated object consisting of many connected parts and joints. Therefore, for applications that involve HCI one can find many challenges to establish a system with high detection and recognition accuracy for hand posture and/or gesture. Hand posture is defined as a static hand configuration without any movement involved. Meanwhile, hand gesture is a sequence of hand postures connected by continuous motions. During the past decades, many approaches have been presented for hand posture and/or gesture recognition. In this paper, we provide a survey on approaches which are based on Hidden Markov Models (HMM) for hand posture and gesture recognition for HCI applications.
Sustained impact of anticoagulant control achieved in an anticoagulation management service after transfer of management to the primary care physician.

STUDY OBJECTIVES
To determine whether the impact of anticoagulant control achieved in an Anticoagulation Management Service (AMS) is sustained after transfer of anticoagulation management to the primary care physician (PCP), and to assess patient satisfaction with their anticoagulation management by both the AMS and PCP.


DESIGN
Prospective, randomized trial.


SETTING
Pharmacist-directed ambulatory AMS located in a tertiary medical care facility and PCP practices in Canada.


PATIENTS
Sixty-two adults who had received at least 6 months of warfarin therapy managed by the AMS.


INTERVENTION
Patients were randomly assigned to remain with AMS care (32 patients) or to transfer their anticoagulation management care to their PCP (30 patients). After 4.5 months of care, patients in both groups completed a validated survey instrument assessing their satisfaction with the management of their warfarin therapy.


MEASUREMENTS AND MAIN RESULTS
Of 295 patients screened, most were excluded from the study for denying consent or for having previous bleeding or clotting complications while taking warfarin. Patients in the AMS and PCP groups who completed the study were similar in age (median 70 and 76 yrs, respectively), and most had atrial fibrillation as an indication for warfarin (75% and 83%, respectively). The primary outcome measure-mean percentage of time within the desired international normalized ratio (INR) range after 6 months-was compared between the two groups, using both the actual range (INR 2.5 ± 0.5) and an expanded range (INR 2.5 ± 0.7). No significant difference was noted in this outcome between the groups (73.5 ± 19.1% vs 76.9 ± 24.5% for the AMS vs PCP groups, p=0.54). Other outcome measures were rates of thrombotic and hemorrhagic events resulting in emergency department visits or hospitalizations, patients' overall satisfaction with warfarin therapy, and patients' preferred anticoagulation management strategy. Two hemorrhagic events and one thrombotic event occurred in each group. Patients were more satisfied with their anticoagulant management by the AMS relative to PCP care (p=0.01), and given the choice, patients preferred AMS care (p=0.001).


CONCLUSION
During this 6-month trial, anticoagulation control did not significantly differ between patients who continued to receive anticoagulation management by the AMS and those who transferred to their PCP for anticoagulation management, indicating that the effects of AMS care were sustained. Although patients were more satisfied and preferred to stay with AMS care, this study shows that select patients could have their anticoagulation care transferred to their PCP without compromising anticoagulation control.

A modal pushover analysis procedure to estimate seismic demands for unsymmetric‐plan buildings

Based on structural dynamics theory, the modal pushover analysis procedure (MPA) retains the conceptual simplicity of current procedures with invariant force distribution, now common in structural engineering practice. The MPA procedure for estimating seismic demands is extended to unsymmetric-plan buildings. In the MPA procedure, the seismic demand due to individual terms in the modal expansion of the effective earthquake forces is determined by nonlinear static analysis using the inertia force distribution for each mode, which for unsymmetric buildings includes two lateral forces and torque at each floor level. These “modal” demands due to the first few terms of the modal expansion are then combined by the CQC rule to obtain an estimate of the total seismic demand for inelastic systems. When applied to elastic systems, the MPA procedure is equivalent to standard response spectrum analysis (RSA). The MPA estimates of seismic demand for torsionally-stiff and torsionally-flexible unsymmetric systems are shown to be similarly accurate as they are for the symmetric building; however, the results deteriorate for a torsionally-similarly-stiff unsymmetric-plan system and the ground motion considered because (a) elastic modes are strongly coupled, and (b) roof displacement is underestimated by the CQC modal combination rule (which would also limit accuracy of RSA for linearly elastic systems).
A Normalization scheme for Terrestrial LiDAR Intensity Data by Range and Incidence Angle

Automatic registration, classification and segmentation of Terrestrial Laser Scanner (TLS) data are of great interest in Geoinformatics & Autonomous vehicle research. Along with dense and accurate 3D geometric data, laser scanners also collect return intensity information. Inclusion of this spectral information has potential to improve the working of the above mentioned processes. However, these intensity values need to be normalized, prior to their use, as they are subject to a large number of errors. This paper presents a technique to carry out normalization of intensity values using the range and incidence angle corrections. The developed approach has been tested on a large number of data and results are found satisfactory. Keywords— Terrestrial Laser Scanner, LiDAR, Intensity, Normalization, Incidence angle correction
Cognitive Adaptations for Social Exchange

INTRODUCTION Is it not reasonable to anticipate that our understanding of the human mind would be aided greatly by knowing the purpose for which it was designed? Research Background The human mind is the most complex natural phenomenon humans have yet encountered , and Darwin's gift to those who wish to understand it is a knowledge of the process that created it and gave it its distinctive organization: evolution. Because we know that the human mind is the product of the evolutionary process, we know something vitally illuminating: that, aside from those properties acquired by chance, the mind consists of a set of adaptations, designed to solve the long-standing adaptive problems humans encountered as hunter-gatherers. Such a view is uncontroversial to most behavioral scientists when applied to topics such as vision or balance. Yet adaptation-ist approaches to human psychology are considered radical-or even transparently false-when applied to most other areas of human thought and action, especially social behavior. Nevertheless, the logic of the adaptationist postion is completely general , and a dispassionate evaluation of its implications leads to the expectation that humans should have evolved a constellation of cognitive adaptations to social life. Our ancestors have been members of social groups and engaging in social interactions for millions and probably tens of millions of years. To behave adaptively, they not only needed to construct a spatial map of the objects disclosed to them by their retinas, but a social map of the persons, relationships, motives, interactions, emotions, and intentions that made up their social world. Our view, then, is that humans have a faculty of social cognition, consisting of a rich collection of dedicated, functionally specialized, interrelated modules (i.e., functionally isolable subunits, mechanisms, mental organs, etc.), organized to collectively guide thought and behavior with respect to the evolutionarily recurrent adaptive problems posed by the social world. Nonetheless, if such a view has merit, it not only must be argued for on theoretical grounds-however compelling-but also must be substantiated by experimental evidence, as well as by converging lines of empirical s u p Port drawn from related fieldssuch as neuroscience, linguistics, and anthropology. The 164 COOPERATION eventual goal is to recover out of carefully designed experimental studies "high-reso-lution" maps of the intricate mechanisms involved. Such an approach is intended to exploit the signal virtue of cognitive psychology: With its emphasis on mechanisms, cognitive approaches allow causal pathways to be precisely specified …
The Relationship Between Mandatory Divorce Education and Level of Post-Divorce Parental Conflict

Abstract This study assessed the association between conflict between divorced parents and their attendance or nonattendance at a divorce education program. A telephone interview was done with 160 individuals who participated in the education program and 59 individuals who did not. Both males and females in the nonattendance group had higher conflict scores than the attendance group. Attendance at the divorce education class was found to be associated with whether a subject will return to court or not. Those who attended were less likely to return to court related to the divorce.
Gothenburg very early supported discharge study (GOTVED) NCT01622205: a block randomized trial with superiority design of very early supported discharge for patients with stroke

BACKGROUND
Stroke is the disease with the highest costs for hospital care and also after discharge. Early supported discharge (ESD) has shown to be efficient and safe and the best results with well-organised discharge teams and patients with less severe strokes. The aim is to investigate if very early supported discharge (VESD) for stroke patients in need for on-going individualised rehabilitation at home is useful for the patient and cost effective.


METHODS/DESIGN
A randomized controlled trial comparing VESD with ordinary discharge.


INCLUSION CRITERIA
confirmed stroke, >18 years of age, living within 30 min from the stroke unit, on day 2 0-16 points on the National institute of health stroke scale (NIHSS) and 50-100 points on the Barthel Index (BI), with BI 100 then the patient can be included if the Montreal Cognitive Assessment is < 26. Exclusion criteria are: NIHSS >16, BI < 50, life expectancy < 1 year, inability to speak or to communicate in Swedish. The inclusion occurs on day 4 and in block randomization of 20 and with blinded assessor.


PRIMARY OUTCOME
levels of anxiety and depression.


SECONDARY OUTCOMES
independence, security, level of function, quality of health, needs of support in activities of daily living and caregiver burden. Power calculation is based on the level of anxiety and with a power of 80%, p-value 0.05 (2 sided test) 44 persons per group are needed. Data is gathered on co-morbidity, re-entry to hospital, mortality and a health economic analysis. Interviews will be accomplished with a strategic sample of 15 patients in the intervention group before discharge, within two weeks after homecoming and 3 months later. Interviews are also planned with 15 relatives in the intervention group 3 months after discharge.


DISCUSSION
The ESD studies in the Cochrane review present hospital stays of a length that no longer exist in Sweden. There is not yet, to our knowledge, any study of early supported discharge with present length of hospital stay. Thus it is not clear if home rehabilitation nowadays without risks, is cost effective, or with the same patient usefulness as earlier studies.
