Uniform Inference in Predictive Regression Models

The restricted likelihood has been found to provide a well-behaved likelihood ratio test in the predictive regression model even when the regressor variable exhibits almost unit root behavior. Using the weighted least squares approximation to the restricted likelihood obtained in Chen and Deo, we provide a quasi restricted likelihood ratio test (QRLRT), obtain its asymptotic distribution as the nuisance persistence parameter varies, and show that this distribution varies very slightly. Consequently, the resulting sup bound QRLRT is shown to maintain size uniformly over the parameter space without sacrificing power. In simulations, the QRLRT is found to deliver uniformly higher power than competing procedures with power gains that are substantial.
RELATIONSHIPS BETWEEN VERTICAL AND HORIZONTAL ROADWAY ALIGNMENTS AND THE INCIDENCE OF FATAL ROLLOVER CRASHES IN NEW MEXICO AND GEORGIA

Survey data on curvature and grade collected at the sites of fatal single-vehicle rollover crashes and at random comparison sites in New Mexico and Georgia were analyzed to determine the relationship of horizontal and vertical alignment to such crashes. The results showed that road sections with extreme horizontal and vertical alignments were as much as 50 times more common at crash sites than at comparison sites. Although sharp left curves and steep downgrades were over-represented in both states, the relative importance of downgrades was greater in New Mexico than in Georgia. Because the relative importance of the two alignments can be expected to vary in other states as well, no overall set of priorities for hazard identification was developed. It is recommended that each state develop its own priorities for hazard identification based on comparisons between the bivariate curve-grade distributions of fatal single-vehicle crash sites and those of a representaive roadway sample. A method for setting such priorities that can be used by individual states is presented.
Pathological Features of Reinnervated Skeletal Muscles Following Crush Injury of the Sciatic Nerve in Ob/ob Mice

Background: Obesity is a factor for insufficient improvement of motor function for peripheral nerve disorders. The aims of this study were to evaluate the skeletal muscles during denervation and re-innervation following nerve crush injury in ob/ob mice. Methods: Experiments were performed on the skeletal muscles of the hindlimbs in 20 male leptin-deficient (ob/ob) mice and control mice. Firstly, the characteristics of the gastrocnemius muscles in the mice were evaluated by histological analysis, immunohistological analysis, and Sircol-collagen assay after measurement of body weight and wet weight of the skeletal muscles and by walking tracking analysis. In the histological analysis, nicotinamide adenine dinucleotide tetrazolium reductase (NADH-TR) staining, oil red O staining, and Picro-sirius red staining were performed to assess the type of myofibers, lipid accumulation, and collagen deposition, respectively. Then, the models for denervation and re-innervation were made by crushing the sciatic nerves with smooth forceps. The same assessments were performed on the skeletal muscles of nerve crush models.Results: The wet weight of the gastrocnemius muscles was significantly less in the ob/ob mice than the control mice, whereas body weight was significantly more. Histological analyses demonstrated a smaller cross-sectional area of type II fibers and increase of type I fiber grouping of the skeletal muscles in the ob/ob mice. In addition, there was excessive deposition of lipids and collagens between the myofibers. Following the nerve injury, the recovery of motor function was equal between both groups, while the cross-sectional area of type II fibers was significantly smaller in the ob/ob mice than the control mice at 4 weeks. Furthermore, the denervated muscles showed an increase in collagen deposition to the area of intermyofibers, which were predominant in the ob/ob mice after the nerve injury.Conclusions: The present study showed an increase of collagen deposition, delayed recovery of type II myofibers, and type I fiber grouping during denervation and re-innervation in the skeletal muscles of ob/ob mice. We suggest through these findings that the reduction of contractile force could be one of causes of insufficient improvement in peripheral nerve disorders of obese individuals.
Aircraft Simulators and Pilot Training

Flight simulators are built as realistically as possible, presumably to enhance their training value. Yet, their training value is determined by the way they are used. Traditionally, simulators have been less important for training than have aircraft, but they are currently emerging as primary pilot training vehicles. This new emphasis is an outgrowth of systems engineering of flight training programs, and a characteristic of the resultant training is the employment of techniques developed through applied research in a variety of training settings. These techniques include functional context training, minimizing over-training, effective utilization of personnel, use of incentive awards, peer training, and objective performance measurement. Programs employing these and other techniques, with training equipment ranging from highly-realistic simulators to reduced-scale paper mockups, have resulted in impressive transfer of training. The conclusion is drawn that a proper training program is essential to realizing the potential training value of a device, regardless of its realism.
Black-Box identification of automated discrete event systems

This thesis deals with the identification of automated discrete event systems (DES) operating in an industrial context. In particular the work focuses on the systems composed by a plant and a programmable logic controller (PLC) operating in a closed loop- the identification consists in obtaining an approximate model expressed in interpreted Petri nets (IPN) from the observed behaviour given under the form of a single sequence of input-output vectors of the PLC. First, an overview of previous works on identification of DES is presented as well as a comparative study of the main recent approaches on the matter. Then the addressed problem is stated- important technological characteristics of automated systems and PLC are detailed. Such characteristics must be considered in solving the identification problem, but they cannot be handled by previous identification techniques. The main contribution in this thesis is the creation of two complementary identification methods. The first method allows constructing systematically an IPN model from a single input-output sequence representing the observable behaviour of the DES. The obtained IPN models describe in detail the evolution of inputs and outputs during the system operation. The second method has been conceived for addressing large and complex industrial DES- it is based on a statistical approach yielding compact and expressive IPN models. It consists of two stages- the first one obtains, from the input-output sequence, the reactive part of the model composed by observable places and transitions. The second stage builds the non observable part of the model including places that ensure the reproduction of the observed input-output sequence. The proposed methods, based on polynomial-time algorithms, have been implemented in software tools, which have been tested with input-output sequences obtained from real systems in operation. The tools are described and their application is illustrated through two case studies.
Genetic Diversity and Population Structure of Plasmodium Falciparum in Nigeria: Insights From Microsatellites Loci Analysis

BackgroundMalaria remains a public health burden especially in Nigeria. To develop new malaria control and elimination strategies or refine existing ones, understanding parasite population diversity and transmission patterns is crucial. MethodsIn this study, we characterized parasite diversity and structure of Plasmodium falciparum isolates from 633 dried blood spot samples in Nigeria, using 12 microsatellite loci of P. falciparum. These microsatellites were amplified via semi-nested polymerase chain reaction (PCR) and fragments were analyzed using GeneMapper and GENALEX 6.5. ResultsEstimates of parasite diversity such as Mean complexity of infection (range: 1.71-2.66) and Expected heterozygosity (range: 0.76-0.82) were high, while parasite population sub-structuring was low (Analysis of molecular variance= 0.039, Fixation index= 0.038 and Linkage disequilibrium= 0.0219). Conclusion We conclude that the high level of genetic diversity and low population structuring in this study suggests that parasite populations circulating in Nigeria are homogenous. This implies that a uniform control strategy will be effective across the six geographical zones of Nigeria. The results obtained can be used as a baseline for parasite diversity and structure, aiding in the formulation of appropriate therapeutic and control strategies in Nigeria.

Populism as Dog-Whistle Politics: Anti-Elite Discourse and Sentiments toward Out-Groups

Past research has devoted more attention to the consequences of populism for party politics and governance than to the effects of populist claims on public attitudes—and particularly, to how populism interacts with nationalism to exacerbate exclusionary beliefs among the public. Using online survey experiments, we examine whether exposure to populism increases out-group antipathy among white Democrats and Republicans. In Study 1, we randomly assign respondents to three conditions featuring vignettes based on political speeches: a morally neutral argument, a populist critique of political elites, and a morally framed anti-immigration appeal. We then assess respondents’ sentiments toward Latinos, an ethnic group commonly vilified in U.S. right-wing political discourse. The results demonstrate that exposure to populist rhetoric alone results in lower feeling-thermometer ratings of Latinos, but only among Republicans. Study 2 uses a similar design to evaluate the link between left-wing economic populism and economic nationalism: the populist condition features a critique of economic elites, the nationalist condition blames China for the offshoring of U.S. jobs, and the outcome variable measures respondents’ sentiments toward China. Economic nationalism generates increased chauvinism among conservative Democrats but economic populism does not. Together these findings suggest that the cross-domain spillover effects between nationalism and populism observed in Study 1 are driven by the discursive bundling of anti-elite talk with ethno-nationalism on the right, which stands in contrast to the decoupling of economic populism and economic nationalism on the left. The former has effectively turned populism into a form of dog-whistle politics among Republicans.
The Geometry Effect in a Pioneering Experimental Study on the Batch Crystallization of the CAM

Abstract: Far from being equivalent to host the process, the vessels play an active role in the crystallization thanks to their differently shaped bottoms. It was clearly pointed out through a meticulous experimental research on the batch crystallization of CAM (citric acid monohydrate) carried out in the years 1997-1998 by the author at the historic laboratories of “La Sapienza” University of Rome. Such pioneering M.Sc. thesis, supervised by Prof. Barbara Mazzarotta (Department of Chemical Engineering), was already summarized in an informative essay but, since the crystallization operating conditions to optimize were illustrated “collectively”, it seemed necessary a further paper expounding uniquely the geometry effect. Our aim is to use all the data, collected and simulated, in order to show why the round-bottomed crystallizer performed better than the conical-bottomed one with the CAM from aqueous solutions, and why we should discard the flat-bottomed crystallizers. Key words: Batch crystallization, citric acid monohydrate, flat bottom, round bottom, conical bottom.

EFFECTIVENESS OF THORAX & PELVIS SIDE AIRBAG FOR IMPROVED SIDE-IMPACT PROTECTION

In recent years, side-impact crashes in the US between SUVs (Sports Utility Vehicle) or LTVs (Light Trucks & Vans) and passenger cars are increasing, resulting in a high number of serious or fatal injuries. It has become an important task to reduce body injury levels, not only to the head, but to the thorax and pelvis as well. One way to protect the occupant’s thorax and pelvis in side-impact crash is T&P SAB (Thorax & Pelvis Side Airbag). This research paper will show a reduction of injury levels as a result of T&P SAB, using IIHS (Insurance Institute for Highway Safety) SUV side-impact crash conditions in MADYMO simulation and sled test results. Furthermore, analyses of the pelvis area were conducted using THUMS Simulation. It was confirmed that T&P SAB has the potential to protect the occupant’s thorax and pelvis during side-impact crash, as well as reduce the level of injury.
Passive aeroelastic tailoring for optimal flapping wings

I N AN effort to overcome many of the Reynolds number limitations associated with micro air vehicles (MAVs) much attention has turned to the investigation of flapping flight. Biologists have studied bird and insect flight empirically for quite some time. A good review of this material can be found in Refs. 1, 2, and 3 while some interesting recent work can be found in Refs. 4, 5, and 6. One thing that is clear is that all of these creatures use two specific mechanisms to overcome the small-scale aerodynamic limitations: flexible wings and flapping wings. Birds and insects exploit the coupling between flexible wings and aerodynamic

COOPERS: co-operative networks for intelligent road safety

COOPERS addresses the subject of co-operative systems for road transport in a very specific and unique way. As most of the previous R and D projects in this field focus to autonomous in-car systems or vehicle-to-vehicle communication, COOPERS tackles the enhancement of 'intelligence' of the road telematics infrastructure, so that the infrastructure at the end of the project is able to communicate/ co-operate with the vehicles and vice versa (A). For the covering abstract of the conference see ITRD E212343.
Management Outcome and Associated Factors among Intestinal Obstruction Patients Treated Surgically, Eastern Ethiopia

Background Intestinal obstruction is a global problem consuming much in terms of surgical services. It is a common surgical emergency and a significant health problem in Ethiopia. Several factors contribute to poor management outcomes in the case of intestinal obstruction. Post-operative mortality rate ranges from 3% to 30%. Despite this high rate of mortality, there is no recently published literature that has explored Intestinal Obstruction and its associated factors at Chiro General Hospital. Methods Institution based cross-sectional study was conducted among 254 of patients admitted with Intestinal obstruction who treated surgically at Chiro General Hospital. Data were collected using checklists from individual patient cards by trained three BSc nurses from 13 to 18 July 2018 and completeness of data collection was checked every day by the principal Investigator. Data were entered to Epi-Data version 3.1 computer software and exported to SPSS statistical software version 22 for analysis. Bivariable binary logistic regression was used to saw the association between each independent variable and dependent variable. All variables with P-value < 0.2 during bi-variable analyses were considered for multivariable logistic regression analyses. Odds ratio along with 95%CI were estimated to measure the strength of the association. Level of statistical significance was declared at p value less or equal to 0.05. Results In this study the magnitude of unfavorable outcome of Intestinal Obstruction was 21.3% (95% CI: (16.5, 26.4). Age group of 55 years or above [AOR=2.9, 95%CI: (1.03, 8.4)], duration of illness of 24hrs or above [AOR=3.1, 95%CI: (1.03, 9.4)], pre-operative diagnosis of gangrenous SBO & gangrenous LBO [(AOR=3.6, 95%CI: (1.3, 9.8)), (AOR=4.2, 95%CI: (1.3, 13.7))], respectively were significantly associated with unfavorable outcome. Conclusions The magnitude of unfavourable management outcome of patients with Intestinal obstruction who treated surgically in this study was high. Old age, late presentation of illness and gangrenous bowel obstruction were significantly associated with unfavourable management outcome. So that early detection prompt management of patients with Intestinal obstruction reduce the occurrence of unfavourable outcome of patients.
A Statewide Analysis of Bicycling in New Jersey

ABSTRACT A statewide survey of bicycling behavior was conducted for the State of New Jersey. Our primary objective was to analyze factors associated with bicycling behavior. Most people who bicycle in the state do so for recreational purposes, thus our analysis provides information primarily on recreational bicycling. We find from our logit and ordered probit models that the propensity to bicycle and the frequency of bicycling are driven primarily by demographic and socioeconomic factors. We also analyze various place-based factors and find that in general most have no statistical effect. Exceptions include areas with higher population density and areas with parks and playgrounds, both being associated with more bicycling. Results provide useful information for planners seeking to provide facilities that may increase the level of recreational bicycling, which is known to improve public health.
Standardized pre-crash-scenarios in digital format on the basis of the VUFO simulation

The sequence of accident events can be classified by three essential phases, the pre-crash sequence, the crash sequence and the post-crash sequence. The level of reliability of the information in the GIDAS database (German In Depth Accident Study) is provided predominantly on the passive side. The period to evaluate active safety systems begins already in the pre-crash sequence. The assessment of the potential of sensor- or communication-based active safety systems can only be accomplished by a detailed analysis of the pre-crash phase. Hence the necessity to analyze the early period of the accident event in detail arises. This is possible with the help of the digital sketches of the accident site and the simulation of the accident by a simulation method of the VUFO GmbH. After simulating the pre-crash scenario it is possible to generate additional and standardized data to describe the pre-crash sequences of an accident in a very high detail. These data are documented in a second database called the GIDAS Pre-Crash Matrix (PCM). The PCM contains various tables with all relevant data to reproduce the pre-crash sequence of traffic accidents from the GIDAS database until 5 seconds before the first collision. This includes parameters to describe the environment data, participant data and motion or dynamic data. This paper explains the creation of the PCM, the simulation itself and the contents and structure of the PCM. With this information of the pre-crash sequence for various accident scenarios an improved benefit estimation and development of active safety systems can be made possible.
