Advanced Mobility Testbed for Dynamic Semi-Autonomous Unmanned Ground Vehicles

Abstract : Integrated simulation capabilities that are high-fidelity, fast, and have scalable architecture are essential to support autonomous vehicle design and performance assessment for the U.S. Army's growing use of unmanned ground vehicles (UGVs). With increased onboard autonomy, advanced vehicle models are needed to analyze and optimize control design and sensor packages over a range of urban and off-road scenarios. Recent work at US Army TARDEC has attempted to develop a high-fidelity mobility simulation of an autonomous vehicle in an off-road scenario using integrated sensor, controller, and multi-body dynamics models. The conclusion was that (a) real-time simulation was not feasible due to the complexity of the intervening formulation, (b) models had to be simplified to speed up the simulation, (c) interfacing the sensors was exceedingly difficult due to co-simulation, (d) the controls developed were very basic and could not be optimized, and (e) a rigid terrain model was used. The research described in this paper is from a collaborative project between US Army TARDEC and NASA Jet Propulsion Laboratory (JPL) to develop an advanced UGV mobility testbed using JPL's ROAMS vehicle modeling capability [2] and to address the aforementioned issues in meeting the US Army's UGV modeling and simulation needs. The ROAMS ground vehicle simulation framework can support tasks ranging from real-time embedded hardware- in-the-loop testing to large-scale Monte Carlo simulation based parametric studies. ROAMS has been successfully used at JPL in several space mission-critical scenarios for NASA across multiple domains (cruise/orbiter, landers, and rovers). ROAMS is unique in its integrated approach to handling the high-fidelity dynamics, sensors, environ- ment, control, and autonomy models that are required for such highly complex missions and are key attributes of future Army unmanned ground vehicles.

Tumor necrosis factor- (cid:1) upregulates 11 (cid:2) -hydroxysteroid dehydrogenase type 1 expression by CCAAT/enhancer binding protein- (cid:2) in HepG2 cells

11 -hydroxysteroid dehydrogenase type 1 expression by CCAAT/enhancer binding protein- (cid:2) in HepG2 cells. 2009. enzyme 11 (cid:2) -hydroxysteroid dehydrogenase type 1 (11 (cid:2) -HSD1) catalyzes the conversion of inactive to active glucocorticoids. 11 (cid:2) -HSD1 plays a crucial role in the pathogenesis of obesity and controls glucocorticoid actions in inﬂammation. Several studies have demonstrated that TNF- (cid:1) increases 11 (cid:2) -HSD1 mRNA and activity in various cell models. Here, we demonstrate that mRNA and activity of 11 (cid:2) -HSD1 is increased in liver tissue from transgenic mice overexpressing TNF- (cid:1) , indicating that this effect also occurs in vivo. To dissect the molecular mechanism of this increase, we investigated basal and TNF- (cid:1) -induced transcription of the 11 (cid:2) -HSD1 gene ( HSD11B1 ) in HepG2 cells. We found that TNF- (cid:1) acts via p38 MAPK pathway. Transient transfections with variable lengths of human HSD11B1 promoter revealed highest activity with or without TNF- (cid:1) in the proximal promoter region ( (cid:3) 180 to (cid:4) 74). Cotransfection with human CCAAT/enhancer binding protein- (cid:1) (C/EBP (cid:1) ) and C/EBP (cid:2) -LAP expression vectors activated the HSD11B1 promoter with the strongest effect within the same region. Gel shift and RNA interference assays revealed the involvement of mainly C/EBP (cid:1) , but also C/EBP (cid:2) , in basal and only of C/EBP (cid:2) in the TNF- (cid:1) -induced HSD11B1 expression. Chromatin immunoprecipitation assay conﬁrmed in vivo the increased abundance of C/EBP (cid:2) on the proximal HSD11B1 promoter upon TNF- (cid:1) treatment. In conclusion, C/EBP (cid:1) and C/EBP (cid:2) control basal transcription, and TNF- (cid:1) upregulates 11 (cid:2) -HSD1, most likely by p38 MAPK-mediated increased binding of C/EBP (cid:2) to the human HSD11B1 promoter. To our knowledge, this is the ﬁrst study showing involvement of p38 MAPK in the TNF- (cid:1) mediated 11 (cid:2) -HSD1 regulation, and that TNF- (cid:1) stimulates enzyme activity in vivo.
Defense-related proteins involved in sugarcane responses to biotic stress

Abstract Sugarcane is one of the most important agricultural crops in the world. However, pathogen infection and herbivore attack cause constant losses in yield. Plants respond to pathogen infection by inducing the expression of several protein types, such as glucanases, chitinases, thaumatins, peptidase inhibitors, defensins, catalases and glycoproteins. Proteins induced by pathogenesis are directly or indirectly involved in plant defense, leading to pathogen death or inducing other plant defense responses. Several of these proteins are induced in sugarcane by different pathogens or insects and have antifungal or insecticidal activity. In this review, defense-related proteins in sugarcane are described, with their putative mechanisms of action, pathogen targets and biotechnological perspectives.
An inhibitor to fibrin stabilizing factor (FSF, factor XIII).

An inhibitor to fibrin stabilizing factor (FSF, factor XIII), associated with a bleeding tendency, was demonstrated in a 24 years old female. The inhibitor was most likely a γG-globulin. FSF and inhibitor were both present in the patient's plasma, and could be separated by euglobulin precipitation. The inhibitor was acting very rapid and was effective even when added during fibrin polymerization.
An evaluation of medical student behaviours in communication

An evaluation of fourth‐year medical student behaviours in communication with real patients in general practice is reported using two different formats of rating scale. The study was performed in the clinical base of the Department of General Practice, the Queen's University, Dunluce Health Centre, Belfast. In all, 475 interviews were rated, 238 being first interviews and 237 second interviews. The format of the rating scale was not found to be a significant variable. Factor analysis of the rating scale item scores produced five factors, which fell into two clear groupings. Factors 2 and 4 represent communication skills, which could have been acquired through normal social learning. Factors 1, 3 and 5 constitute more technical and professional skills not usually employed in normal social intercourse. Analysis of data from first and subsequent interviews indicates that the students in the study had acquired professional skills, which require special teaching. These are identified in Factors 1, 3 and 5 and require a proper emphasis in training.
Verilog-A Modeling of Radiation-Induced Mismatch Enhancement

Physical model of TID effects is embedded into BSIM3v3 model implemented using Verilog-A. Radiation-induced mismatch enhancement due to the combined action of technology variations and electrical bias difference is demonstrated by simulation. It is shown that the total ionizing dose degradation of circuit components under inequivalent electric field conditions could lead to mismatch of internal circuit parameters, which results in a change to circuit output mismatch parameters.
N-(2-Chlorobenzoyl)-4-methylbenzenesulfonamide

In the title compound, C14H12ClNO3S, the C=O bond is syn to the Cl substituent in the adjacent benzene ring. The C—S—N—C torsion angle is −80.6 (6)°. The chlorobenzoyl ring is disordered and was refined using a split model [occupancy ratio 0.537 (3):0.463 (3)]. In the crystal, molecules are linked by pairs of N—H⋯O(S) hydrogen bonds, forming inversion dimers.
Exploring the exponential integrators with Krylov subspace algorithms for nonlinear circuit simulation

We explore Krylov subspace algorithms to calculate ϕ functions of exponential integrators for circuit simulation. Higham [1] pointed out the potential numerical stability risk of ϕ functions computation. However, for the applications to circuit analysis, the choice of methods remains open. This work inspects the accuracy of matrix exponential and vector product with Krylov subspace methods, and identifies the proper approach to achieving numerically stable solutions for nonlinear circuits. Empirial results verify the quality of the proposed methods using various orders of ϕ functions. Furthermore, instead of Newton-Raphson (NR) iterations in conventional methods, an iterative residue correction algorithm is devised for nonlinear system analysis. The stability and efficiency of our methods are illustrated with experiments.
An Advanced EAF Model for Voltage Fluctuation Propagation Study

This paper presents an improved dynamic voltage-current model of an ac electric arc furnace (EAF) for multiple operation stages and for the study of propagations of voltage fluctuations in a power network associated with the EAF in operating stages. The EAF model is developed based on wavelet-transform and neural-network-based methods by training actual measured EAF current and voltage data. The proposed EAF model is then implemented in an actual 161-kV power system for simulations. The voltage fluctuations at other buses due to the EAF in operation are then assessed. Simulation and measured results show that the improved hybrid EAF model is accurate and is suitable for voltage fluctuation assessment when the actual measurements in the power network are limited or not available while the EAF is in operation or before the similar types of EAFs are to be installed in the system.
Practical Applications of Numerical Modeling using Aqua-FE: A Case Study

A numerical model of an American Soybean Association (ASA) cage system was constructed using a finite element program developed at the University of New Hampshire (UNH) called Aqua-FE. The small volume, high density aquaculture system was modeled to determine how the system will operate in normal and extreme environmental conditions. The goals of the study were to determine the maximum loads in the system during tropical storm conditions and determine a similar cage system's response under specified environmental criteria. The cage is currently deployed in Weitou Bay, China. The system consists of a 100 m3 cage (2 m times 4.5 m times 7 m) secured in a single point mooring. The rigid HDPE cage is held to the mooring by two sets of bridle lines, attached to the upper and lower cage framework. Chain ballast hangs below the lower cage rim providing a restoring force. A deadweight anchor secures the system to the seafloor. A 90 kg float suspends the single point mooring and serves as a tie-up location for servicing vessels. Aqua-FE can apply wave and current loading on truss and buoy elements by utilizing the Morrison equation adopted for analysis of aquaculture net pen systems. The algorithm employs a nonlinear Lagrangian formulation to account for large displacements of structural elements. In addition, the unconditionally stable Newmark direct integration scheme is adopted to solve the nonlinear equations of motion. Hydrodynamic forces on the structural elements are calculated using the Morison equation modified to account for relative motion between the structural element and the surrounding fluid. Maximum loads in the mooring gear approached 56 kN during the storm events. When various current velocities were applied, the cage submerged to a maximum depth of 16.4 meters
E-learning Systems Evaluation with Data Envelopment Analysis and Bayesian Networks

This study uses data envelopment analysis and Bayesian networks in e-learning systems evaluation and classification, respectively. By maximizing the weighted summed-outputs-to-weighted-summed-inputs ratio, we obtain the scores of individual as well as groups of reviewers from relative efficiency perspectives. The efficiencies are used as training data to construct the classification model for further decision and pre-evaluation in e-learning systems performance.
DNase I hypersensitivity is independent of endogenous topoisomerase II activity during chicken erythrocyte differentiation

Endogenous topoisomerase II cleavage sites were mapped in the chicken beta A-globin gene of 12- to 14-day embryonic erythrocytes. A major topoisomerase II catalytic site was mapped to the 5' end of the globin gene which contained a nucleosome-free and DNase I-hypersensitive site and additional but minor sites were mapped to the second intron and 3' of the gene to a tissue-specific enhancer. Cleavage sites, mapped in situ by indirect end labeling, were aligned to single-base-pair resolution by comparison to a consensus sequence derived for vertebrate topoisomerase II catalytic sites. In contrast to embryonic erythrocytes, endogenous topoisomerase II cleavages were not detected in erythrocytes from peripheral blood of adult chickens; therefore, as the transcriptional activity of the beta A-globin gene declines during terminal differentiation of erythrocytes, the activity of topoisomerase II in situ declines as well, despite the fact that DNase I hypersensitivity persists. The results showed that DNase I-hypersensitive chromatin can be maintained in the absence of topoisomerase II activity and suggested that topoisomerase II acts at hypersensitive sites because of an inherent attraction to some preexisting combination of DNA sequence or chromatin structure associated with DNase I-hypersensitive regions.
Software power optimizations in an embedded system

The topic of reducing power dissipation in embedded systems has received considerable attention in the recent years. Techniques have been reported to minimize energy dissipation through (a) selection of better algorithms for the application e.g. DSP algorithms that require fewer number of operations to perform a task such as filtering (b) minimizing state transitions and switching activity in the hardware implementation, and (c) reducing the operating supply voltage by changing the architecture of the system e.g. through the use of pipelining. However, power dissipation is often neglected when developing the software for embedded systems. Software optimization techniques can be used to reduce the cost, size, and power dissipation in embedded systems without adding to system overheads. In this paper, we view the power dissipation as consisting of two parts, the power dissipated in the application-specific integrated circuits (hardware power) and the power dissipated by the CPU, memory and associated busses (software power). We provide a trace-based technique to estimate software power and study the effect of different code optimization techniques on software power, performance and code size.
Measurements of large-scale variations caused by vehicular traffic in small-cells

This paper presents and characterizes large-scale variations of received power generated by vehicular traffic crossing a radio link. Measurements in the 2 GHz band for several small-cell configurations involve various transmitter heights, link distances and urban densities. Observations showed that stronger losses up to 30 dB are due to medium to high vehicles. Lower vehicles have a smaller impact in links perpendicular to traffic, but amplitude variations and duration can reach larger values when the receiver is at cell radius limits.
A novel design method for improving sleeve antenna performance

This paper presents a novel design method for improving bandwidth of sleeve antenna. The proposed design method incorporates dual-sleeve structure and end-loaded technology. Two novel sleeve antennas are designed with operation frequency 0.8GHz~2.7GHz and 3.1GHz~10.6GHz based on the proposed method. Simulation results show that the antennas have a 3.4:1 bandwidth with 10-dB return loss and an omnidirectional pattern in the H plane. The peak gain is more than 2dBi over the almost operation frequency.
Inferences of all‐sky solar irradiance using Terra and Aqua MODIS satellite data

Solar irradiance is a key environmental control, and accurate spatial and temporal solar irradiance data are important for a wide range of applications related to energy and carbon cycling, weather prediction, and climate change. This study presents a satellite‐based scheme for the retrieval of all‐sky solar irradiance components, which links a physically based clear‐sky model with a neural network version of a rigorous radiative transfer model. The scheme exploits the improved cloud characterization and retrieval capabilities of the MODerate resolution Imaging Spectroradiometer (MODIS) onboard the Terra and Aqua satellites, and employs a cloud motion tracking scheme for the production of hourly solar irradiance data throughout the day. The scheme was implemented for the Island of Zealand, Denmark (56° N, 12° E) and Southern Arizona, USA (31° N, 110° W) permitting model evaluation for two highly contrasting climates and cloud environments. Information on the atmospheric state was provided by MODIS data products and verifications against AErosol RObotic NETwork (AERONET) data demonstrated usefulness of MODIS aerosol optical depth and total precipitable water vapour retrievals for the delineation of spatial gradients. However, aerosol retrievals were significantly biased for the semi‐arid region, and water‐vapour retrievals were characterized by systematic deviations from the measurements. Hourly global solar irradiance data were retrieved with overall root mean square deviations of 11.5% (60 W m−2) and 26.6% (72 W m−2) for Southern Arizona and the Island of Zealand, respectively. For both regions, hourly satellite estimates were shown to be more reliable than pyranometer measurements from ground stations only 15 km away from the point of interest, which is comparable to the accuracy level obtainable from geostationary satellites with image acquisitions every 15–30 min. The proposed scheme is particularly useful for solar irradiance mapping in high‐latitude regions as data from geostationary satellites experience a gradual degradation in spatial resolution and overall quality with latitude and become unusable above approximately 60° latitude. However, in principle, the scheme can be applied anywhere on the globe, and a synergistic use of MODIS and geostationary satellite datasets may be envisaged for some applications.
External K+ relieves the block but not the gating shift caused by Zn2+ in human Kv1.5 potassium channels

1 We used the whole‐cell recording technique to examine the effect of extracellular Zn2+ on macroscopic currents due to Kv1.5 channels expressed in the human embryonic kidney cell line HEK293. 2 Fits of a Boltzmann function to tail current amplitudes showed that 1 mm Zn2+ shifted the half‐activation voltage from ‐10.2 ± 0.4 to 21.1 ± 0.7 mV and the slope factor increased from 6.8 ± 0.4 to 9.4 ± 0.7 mV. The maximum conductance in 1 mm Zn2+ and with 3.5 mm K+o was 33 ± 7 % of the control value. 3 In physiological saline the apparent KD for the Zn2+ block was 650 ± 24 μm and was voltage independent. A Hill coefficient of 1.0 ± 0.03 implied that block is mediated by the occupation of a single binding site. 4 Increasing the external concentration of K+ ([K+]o) inhibited the block by Zn2+. Estimates of the apparent KD of the Zn2+ block in 0, 5 and 135 mm K+ were 69, 650 and 2100 μm, respectively. External Cs+ relieved the Zn2+ block but was less effective than K+. Changing [K+]o did not affect the Zn2+‐induced gating shift. 5 A model of allosteric inhibition fitted to the relationship between the block by Zn2+ and the block relief by external K+ gave KD estimates of ≈70 μm for Zn2+ and ≈500 μm for K+. 6 We propose that the gating shift and the block caused by Zn2+ are mediated by two distinct sites and that the blocking site is located in the external mouth of the pore.
Non-Participation in a Randomized Controlled Trial: The Effect on Clinical and Non-Clinical Variables

Studies reporting clinical and non-clinical parameters of participants and non-participants of clinical trials are scarce. In the available studies non-participants were likely to show less favourable outcomes than participants on both socioeconomic parameters as well as on caries experience. However, the impact of non-participation on the total sample of the research population is not established. In the present study, as part of baseline data collection for a randomized controlled trial on caries-preventive strategies, 346 parents of children 6.0 years (± 3 months) of age were approached to let their child participate. Sixty parents refused, but 56 of them were willing to fill out the same set of questionnaires and to allow their child to be clinically examined once. Parents from participating children had higher socioeconomic status, were more often of autochthonous origin and scored better on knowledge questions than parents of non-participating children. Furthermore, parents of participating children reported a higher willingness to invest, were more likely to hold on to regular meals and their child had lower levels of plaque compared to non-participating children. Surprisingly, the participating children had higher dmfs scores than the non-participating children. Their care index (fs/ds + fs) was higher than that of non-participating children. Based on the findings of this study, the presumption that non-participating children will show less favourable clinical outcomes cannot be supported. Although participants differed from non-participants, they did not differ from the total population. It is suggested that the external validity of a randomized controlled trial on caries-preventive strategies is not necessarily affected by non-participation bias.
Análisis económico y ambiental de la contaminación por nitratos en el regadío

En el ultimo siglo, la progresiva capitalizacion e intensificacion de la agricultura ha dado lugar a un fuerte aumento en la utilizacion de fertilizantes y plaguicidas de origen industrial. Estos avances tecnologicos han incrementado considerablemente los rendimientos de las actividades agrarias, aunque tal incremento ha ido acompanado del deterioro de la calidad del suelos y aguas, llegando a constituir la causa principal de la degradacion de la calidad de agua en muchas areas del continente europeo. Uno de los problemas de contaminacion de origen difuso que provoca la sobreutilizacion de fertilizantes es la contaminacion del agua por nitratos, que ademas de tener efectos negativos sobre la calidad del agua, constituye una amenaza para la supervivencia de los ecosistemas acuaticos e incluso para la salud humana. En este trabajo se analizan los problemas de contaminacion por nitratos en una zona de regadio situada en el valle medio del Ebro. El analisis se realiza desde una perspectiva economica y en un contexto dinamico. El instrumento matematicoo basico empleado es la programacion dinamica o teoria del control optimo, y para determinar las funciones de rendimiento y contaminacion difusa por nitratos se utiliza el paquete de simulacion de cultivos EPIC. El modelo planteado representa el problema de decision del agricultor sobre las actividades agricolas ligadas a la gestion del agua y a la contaminacion, en el que se considera que el agricultor maximiza el valor actual del margen neto de la explotacion. El agricultor selecciona las asignaciones de fertilizante nitrogenado y de agua de riego a lo largo de un horizonte temporal, sujeto a un conjunto de restricciones de produccion y de disponibilidad de factores productivos. Una vez construido el modelo, se estudian los efectos y la eficiencia de distintas medidas de politica ambiental para controlar la contaminacion por nitrogeno: aumento del precio de
