Cooperative Control for Longitudinal Following and Lateral Lane Changing of Intelligent Cars

: In order to improve the control performance of the intelligent vehicle, by using front and rear wheel active steering technology, in this paper, we study the cooperative control for lane changing and following control of intelligent networked cars. Assuming that the lateral positions of the vehicle in a lane changing transition satisfy five order polynomial constraints, and the longitudinal positions and status information of the vehicle to be followed is obtained by means of inter-vehicle communication. Based on the desired longitudinal and lateral vehicle states, the reference yaw angle for lane changing was generated. Based on the dynamical model of the front and rear wheel steering vehicle, the longitudinal error model of vehicle following and lateral error model of trajectory tracking for lane changing are established. By applying terminal sliding mode technology, the cooperative tracking control law for lane changing and vehicle following was designed. Based on Lyapunov function method, the stability of the control system was obtained. Expected control performance for vehicle following and trajectory tracking for lane changing is verified by the simulation, the asymptotic convergence of longitudinal and lateral position error and yaw angle error is guaranteed.
Seroprevalence and real-time PCR study of Epstein-Barr virus and the value of screening in pretransplant patients

Objective This study was performed to estimate the prevalence of Epstein-Barr virus immunoglobulin M virus capsid antigen (EBV IgM VCA) among healthy blood donors and to confirm the real risk of transfusion transmission by detection of virus load using PCR quantification. Materials and methods A total of 860 apparently healthy Egyptian blood donors were enrolled and tested for EBV IgM VCA. Quantitative PCR was performed for reactive cases for EBV IgM VCA. Results An overall 38 patients were reactive for EBV IgM VCA, constituting 4.4% of the sample. Reactivity of Epstein-Barr virus did not differ significantly as regards sex distribution, blood grouping, Rh factor positivity, and hemoglobin level, but it was significantly higher among upper Egypt participants than among those from other regions (P = 0.006). There was a very high statistically significant positive correlation between the titer of EBV VCA IgM reactive cases and age in the studied group (P = 0.0001 and r = 0.6). PCR was negative for all of the reactive cases. Conclusion Routine screening for Epstein-Barr virus in blood bags is not economical. Screening is highly recommended only for immunocompromised and pretransplant patients. Viremia is not the role in individuals with EBV IgM positive sera, which in turn changes some concepts in organ transplantation.

To evaluate simultaneous fractionated cisplatin and radiation therapy for advanced operable Stage III and IV squamous cell carcinoma (SCC) of the base of tongue (BOT) and hypopharynx.
Crowding Out and Crowding In : Evidence from a Large Organization

Using a dataset that includes every private donation made to the University of California, Los Angeles (UCLA) from 1938 to 2012, we test several hypotheses about how individual donors respond to large private and public grants. Donors may respond differently to government funding than to private grants. California residents, who fund UCLA through their taxes, may respond differently to government funding than non-residents. Our data show that large private grants crowd out smaller private donations to the same unit of the University. Government funding may crowd in private donations, and the magnitude of crowd-in is lower for California residents than for non-California residents.
Wage Risk, On-the-job Search and the Value of Job Mobility

This paper shows that job mobility is a valuable channel in response to labor market shocks for employed workers. I construct a model of wage dynamics jointly with a structural dynamic model of job mobility. The key feature of the model is the specification of wage shocks at the worker-firm match level, for workers can respond to these shocks by changing jobs. The first result is that the variance of match-level shocks is large, and the consequent value of job mobility is substantial and decreasing in the cost of switching jobs. The second result is that true wage risk is more than twice as large as the wage variance observed after job mobility, which is what other papers in the literature have called wage risk.

Modeling of The Lane Changing Motor Vehicle Traffic On Roads with Two Lanes

Abstract: Heterogeneous motor vehicle flow models are developed to take into account of local and major changes such as the increase of motor vehicle types and number, increase of the number of lanes, lane shifting characteristics, overtaking and identification of areas prone to accidents and congestion. Lighthill Whitham and Richards motor vehicle traffic model, investigated how homogeneous vehicles travels in a one dimensional, single lane road; without curvatures. Petrosyan and Balabanyan, in their headway traffic flow model, demonstrated how overtaking of a lead vehicle is difficulty in a single lane road. Due to the potholes realized in the already existing motor vehicle traffic flow models, there was need to work with heterogeneous traffic flow models so as to take care of dimensional heterogeneity, road heterogeneity and vehicle heterogeneity. This study addresses the short falls of the old models and the challenges posed by the increase in motor vehicle traffic ranging from but not limited to head on collisions, head to back collisions, lane changing difficulties, congestion and pedestrian related accidents not forgetting lack of maneuvering space for negotiating sharp corners; such as the Nyabunde black spot corner, in Kisii, Sachangwan deadly stretch, in Nakuru; both in Kenya where deadly accidents have in the recent past occurred resulting to loss of life and property. The study developed heterogeneous motor vehicle traffic flow models, derived a two ensemble traffic composition formulation and established the solutions to the obtained models numerically. Graphical representation of the traffic flow variables with respect to the distance covered on the highway is done using MATLAB. The information obtained from the study is very useful to civil engineers, mechanical engineers, town planners, computer programmers and upcoming mathematicians not forgetting drivers and riders.
A note on the Bruhat decomposition of semisimple Lie groups

Let a split element of a connected semisimple Lie group act on one of its flag manifolds. We prove that each connected set of fixed points of this action is itself a flag manifold. With this we can obtain a generalized Bruhat decomposition of a semisimple Lie group by entirely dynamical arguments. Mathematics Subject Classification 2000: Primary: 22E46, Secondary: 14M15
Expression of Metabolic and Myogenic Factors during two Competitive Seasons in Elite Junior Cyclists

Competitive cyclists subject themselves to a high training volume that follows a seasonal pattern; where extensive phases with long rides in winter to spring dominate the preparative phase of training, while intensive types of exercise during races impact on the athlete during the competition phase from spring to late summer (30). In consequence of training and competition, endurance athletes demonstrate adjustments in energy supply lines and underlying gene expression in exercised muscles (14, 29). The implication of the two former processes in the progression of cycling performance and the seasonal patterning of training in the well-trained endurance athlete is little understood (19, 29).

Free Space Radiation Pattern Reconstruction from Non-Anechoic Data Using the 3D Impulse Response of the Environment

Using impulse response with a 3D algorithm is a novel free-space radiation pattern reconstruction technique with accuracy greater than 1dB in all antenna under test (AUT) azimuth and elevation angle orientations inside a non-anechoic environment. A quantitative comparison between impulse response with a 3D algorithm and impulse response with 2D, a previous technique, is performed using quantifiers. Benefits of the proposed 3D free-space radiation pattern reconstruction algorithm are single-frequency characterization and reuse of the 3D impulse response of the environment.
Homology Inference from Point Cloud Data

In this paper, we survey a common framework of estimating topological information from point cloud data (PCD) that has been developed in the ﬁeld of computational topology in the past twenty years. Speciﬁcally, we focus on the inference of homological information. We brieﬂy explain the main ingredients involved, and present some basic results. This chapter is part of the AMS short course on Geometry and Topology in Statistical Inference . It aims to introduce the general mathematical audience to the problem of topology inference, but is not meant to be a comprehensive review of the ﬁeld in general.
Epidemiology of Physical Activity and Fragility Fractures

Stattin, K. 2020. Epidemiology of Physical Activity and Fragility Fractures. Digital Comprehensive Summaries of Uppsala Dissertations from the Faculty of Medicine 1635. 64 pp. Uppsala: Acta Universitatis Upsaliensis. ISBN 978-91-513-0862-3. Fragility fractures mainly affect elderly individuals and often cause long term pain, loss of function and higher mortality rates. Physical activity improves balance, increases muscle strength and bone mineral density, and may reduce the risk of fragility fractures. The aim of this thesis is to investigate the association between physical activity and fragility fractures. In Paper I the risk of hip and any fracture was investigated across levels of habitual walking/bicycling and exercise in participants from the population-based Cohort of Swedish Men (COSM) and Swedish Mammography Cohort (SMC). Individuals walking/bicycling a maximum of 20 minutes per day had a lower risk of hip and any fracture than individuals who did not walk or bicycle. The risk of hip and any fracture was gradually lower with increasing levels of exercise. In Paper II participants in the cross-country skiing race Vasaloppet were compared to non-participants from the general population, and were found to have a higher risk of any and forearm fracture but a lower risk of hip, proximal humerus and lower leg fracture. There was no difference in the risk of vertebral fracture. In Paper III, the association between physical activity and cardiovascular candidate plasma protein concentrations were analyzed in participants from the EpiHealth cohort and the Swedish Mammography Cohort Clinical. Of 184 assayed proteins, 75 associations with physical activity were discovered and 28 subsequently replicated in multivariable adjusted models. In Paper IV the COSM, SMC and the Vasaloppet cohort were combined to achieve as wide a range of physical activity as possible and a common measure of physical activity was created using generalized structural equation modeling (GSEM). Low levels of physical activity were associated with higher risk of any and hip fracture but lower risk of wrist fracture. Individuals with physical activity close to the median of the combined cohort had the lowest risk of fracture, and higher levels of physical activity was associated with a higher risk of any fracture. In conclusion, physical activity is associated with a lower risk of major fractures such as hip fractures, but may in large quantities increase the risk of wrist and any fracture. Physical activity is associated with more beneficial concentrations of 28 cardiovascular plasma proteins.
Short Introduction to Domination Analysis in Combinatorial Optimization

This paper is chiefly a survey article. It gives a short introduction to domination analysis (DA) and a brief overview of results and applications. We prove three new results, Theorems 4.1, 5.1 and 5.4, that strengthen previously known results. Notice that the proofs of the new results are minor variations of the proofs of their previously known counterparts. Some open problems are also raised. We would refer the interested reader to [17] and [15] for more detailed information. In Section 2 we provide motivation for studying DA, basic terminology and notation. Section 3 considers in some detail the minimum multiprocessor scheduling and overviews several results on other combinatorial optimization problems. Sections 4 and 5 are devoted to results on DA for the greedy algorithm and upper bounds on the maximum domination number for polynomial time traveling salesman heuristics.

Stomach metastasis of low grade endometrial stromal sarcoma

Endometrial stromal sarcomas (ESS) are rare mesenchymal tumors of the uterus. Low-grade endometrial stromal sarcoma (LGESS) constitutes approximately two-thirds of ESS. Metastasis of LGESS can be seen after many years. In the endoscopic examination, a 57-year-old female patient with dyspeptic complaints was diagnosed with mesenchymal originated tumor located in the antrum of the stomach. It is reported that the patient underwent a hysterectomy and unilateral oophorectomy 15 years ago due to vaginal bleeding. A mass in the stomach approximately 5 cm in diameter was detected in the abdominal contrast-enhanced computed tomography. She underwent subtotal gastrectomy and omentectomy, and immunohistological examination was reported as LGESS. As far as we know, it is the first case reported as a LGESS metastasis to stomach so far. We should bear in mind that metastasis of LGESS may be seen after many years. It should be included in differential diagnosis of gastrointestinal stromal tumors.
BSTR BRIGHT LIGHTS REVIEW

Pulmonary arterial hypertension (PAH) is a primary disease of the pulmonary vasculature that finally leads to right ventricular (RV) failure. As a consequence, survival in PAH patients is strongly related to RV function. RV dysfunction occurs after a time-varying period of compensated hypertrophy [1]. The underlying mechanisms driving the transition from this adaptive RV phenotype to a maladaptive remodeling have been poorly investigated. Any molecular patterns can be efficiently triggered to reverse RV failure in PAH nowadays.
EVALUATION OF INFRARED SENSORS AND VISIBLE SPECTRUM SENSORS TO DETECT OIL SPILLS ON ICE

2 ABSTRACT Experiments were conducted December 2, 2016 through December 8, 2016 in the Geophysical Research Facility at the U.S. Army Cold Regions Research and Engineering Laboratory, Hanover, NH, USA to evaluate the applicability of infrared and visible spectrum imagers in the event of an oil spill on an ice surface in Arctic conditions. Once a safe load bearing sea ice sheet was established, a series of measurements were performed to evaluate the effectiveness of the imagers in differentiating between oil covered and clean ice surfaces. Images and data were recorded over a six day period. Two natural snow events occurred, offering a unique experimental opportunity. The angle of incidence of the imaging sensors was designed to simulate what would be seen from bridge deck mounted system. Results of non-intrusive, stand-off detection of surface oil spills in snow and ice conditions are discussed.

High-efficiency Design of Magnetic Actuator considering Thermal- magnetic Properties of Permanent Magnet

Permanent magnet (PM) actuator with Nd-Fe-B magnet has been widely used in household electric appliances and automotive applications because of its high power density. Unfortunately, since Nd-FeB magnet has a demagnetization characteristic at a high driving temperature [1], an unexpected reduction in magnetic performance of actuator occurs frequently in actual driving circumstance [2]. This paper proposes a new design method of PM actuator for improving driving performance with considering the demagnetization characteristic of magnet. Magnetic performance of actuator at high temperature is determined by using both reversible and irreversible demagnetization properties of PM. The optimization problem is formulated to minimize the PM area where the remanent flux is reduced on the load state at a high temperature while satisfying the target magnetic performance within the limited material usage. A level set based topology optimization method [3] is employed to obtain an innovative optimal design of PM. The level set functions, which has a sign for distinguishing the different material domains, are used as design variables to represent the structural boundaries of the PM and the ferromagnetic material (FM) in the actuator. A design example of PM actuator with two loading conditions, a closed-loop and open-loop, is adopted to demonstrate the effectiveness of the proposed method. The performance reductions, 1.4% on a closed-loop and 76.0% on an open-loop, of a reference model at a high temperature are observed due to the demagnetization of PM. The optimal design derived by proposed method has a same PM area against the reference model but the magnetic performances are increased, 1.36% on a closed-loop and 76.5% on an open-loop, at high temperature. It is confirmed that the proposed method is valid for finding the optimal design of demagnetization problem of PM
How accurate is the use of ECGs in the diagnosis of myocardial infarct

The electrocardiogram (ECG) is a fairly accurate test in the diagnosis of myocardial infarction (MI). However, given more sensitive technologies, such as cardiac biomarker testing, its primary role should be as an important adjunct in the evaluation and detection of MI (strength of recommendation [SOR]: A). The sensitivity of ECG for detection of MI is directly related to what is defined as positive findings on the ECG for MI. The single most specific ECG finding is the presence of new ST segment elevation of at least 1 mm (SOR: A). Other findings such as the development of new pathologic Q waves and ST depression can also be valuable in making the diagnosis.
Does Outsourcing Job Search Assistance help Job Seekers Find and Keep Jobs?∗

Finding jobs for long-term unemployed job seekers is a key challenge. We study how Hestia, a private job search assistance organization, compares to the public employment service in Geneva. In a randomized field experiment, we follow unemployment benefit recipients two years prior to five years after assignment to treatment and find that Hestia’s clients enter jobs earlier, especially during the first six months after the start of the experiment. Yet, the initial employment gain dissipates completely, and becomes even negative and significant two years after assignment. Hestia’s clients leave jobs quickly immediately after starting a job, and right after the start of the second year. They also earn less on the job than the control group. All of this suggests that Hestia places job seekers faster but into worse jobs. Despite this, we find that the most pessimistic cost-benefit analysis comes out marginally in Hestia’s favor.

Practitioner’s guide for Neural Networks

The simplest model for a deep neural network is a Fully Connected Neural Network. This constitutes one input layer, one output layer and several hidden layers. Each layer consists of multiple perceptrons (interchangeably referred to as neurons in these notes) that has been discussed earlier. And thus this is also referred to as a multi layer perceptron (MLP). A schematic of this network is shown in Fig. 1.
