Autonomous Lane Changing Using Model Predictive Control (2005)

<div class="htmlview paragraph">This paper takes a look at one of the problems associated with the concept of autonomous control of vehicles in the current traffic environment, namely the changing of lanes. Given the increase in traffic density on highways and interstate roads over the past few decades, safe navigation of individual vehicles has required increased driver attention and diligence to an increased number of visual information cues. The concept of autonomous vehicles operating without driver intervention in the present traffic system appears daunting. One aspect of traffic maneuvering involves changing lanes to a position between two other vehicles. Although this aspect appears straightforward, it is the lack of accurate knowledge of other vehicle maneuvering which makes the task difficult. Using Model Predictive Control (MPC) techniques, the task is addressed in an optimization problem framework.</div>
Variable Expression of Pres1 Antigen in Serum During Chronic Hepatitis B Virus Infection: An Accurate Marker for the Level of Hepatitis B Virus Replication (1990)

The expression of the preS1 antigen of hepatitis B virus in sera from chronic HBsAg carriers was studied using a specific monoclonal antibody F35.25 in an original, double-immunoradiometric assay. The antibody F35.25 recognized an epitope located between amino-acid residues 32 and 53 on the preS1 sequence of the large HBsAg protein. This domain could be involved in the recognition of hepatitis B virus by hepatocyte receptors. PreS1 antigen detection by monoclonal antibody F35.25 closely correlated with the presence of complete virions in the serum of HBsAg carriers, as demonstrated by ultracentrifugation-gradient experiments and electron-microscopical examination. Of the 19 HBsAg carriers with chronic liver disease, preS1 antigen was detected in 17 (90%): all of the 11 HBeAg- and hepatitis B virus-DNA--positive cases (group 1) and six of eight anti-HBe--positive cases with low levels of hepatitis B virus replication (group 2). PreS1 antigen/HBsAg ratios parallel to preS1 antigen titers were significantly higher in the HBeAg-positive group (34% and 1:10(6] than in the anti-HBe--positive group (18% and 1:10(2]. In contrast, preS1 antigen was not detected in 18 (90%) of the 20 HBsAg healthy carriers positive for anti-HBe and negative for serum hepatitis B virus-DNA (group 3). Our results show that in chronic HBsAg carriers the serum expression of preS1 antigen correlates well with the level of hepatitis B virus replication (serum hepatitis B virus-DNA and/or liver HBcAg) and that it may be useful in assessing the clinical importance of the chronic viral infection.
Decentralized Traffic Aware Scheduling in 6TiSCH Networks: Design and Experimental Evaluation (2015)

This paper capitalizes on two emerging trends, i.e., the growing use of wireless at the edge of industrial control networks and the growing interest to integrate IP into said networks. This is facilitated by recent design contributions from the IEEE and the IETF, where the former developed a highly efficient deterministic time-frequency scheduled medium access control protocol in the form of IEEE 802.15.4e timeslotted channel hopping (TSCH) and the latter IPv6 networking paradigms in the form of 6LoWPAN/ROLL, and scheduling approaches in the form of 6TiSCH. The focus of the present work is on advancing the state-of-the-art of deterministic 6TiSCH schedules toward more flexible but equally reliable distributed approaches. In addition, this paper aims to introduce the first implementation of 6TiSCH networks for factory automation environments: it outlines the challenges faced to overcome the scalability issues inherent to multihop dense low-power networks; the experimental results confirm that the naturally unreliable radio medium can support time-critical and reliable applications. These developments pave the way for wireless industry-grade monitoring approaches.
Relationship between differentiation and terminal mitosis: chick sensory and ciliary neurons differentiate after terminal mitosis of precursor cells, whereas sympathetic neurons continue to divide after differentiation (1987)

A population of undifferentiated cells has been characterized during the early development of nodose and ciliary ganglia. This population is defined by the absence of surface markers specific for neurons (tetanus toxin receptor, Q211 antigen) and for glial cells (O4 antigen). These undifferentiated cell populations were isolated from the ganglia and were shown to contain neuronal precursor cells that were able to differentiate in vitro into neurons, as characterized by morphology and surface antigens. Undifferentiated cells were detected during the period of neuronal birth, indicating that dividing neuronal precursor cells do not express neuron-specific surface markers. This was directly shown by 3H-thymidine-labeling studies using nodose ganglia, ciliary ganglia, and dorsal root ganglia. In sympathetic ganglia, however, no undifferentiated neuronal precursor cells were detectable at developmental stages when sympathetic neurons are born. 3H-Thymidine injected during that stage at E7 was incorporated into cells expressing the neuronal markers tetanus toxin receptor and Q211 antigen. Quantitative fluorimetric determination of the DNA content of dissociated sympathetic ganglion cells demonstrated the presence of a population of Q211-positive sympathetic ganglion cells in the G2 phase of the cell cycle. E7 sympathetic ganglion cells expressing neuronal surface markers were also shown to be able to divide in vitro. We have concluded that the relationship between terminal mitosis and the onset of differentiation differs between ganglia of the chick peripheral nervous system: Sympathetic ganglion cells continue to divide after the acquisition of neuronal properties, whereas neuronal precursor cells from other autonomic and sensory ganglia start to differentiate after a terminal mitosis.
Charge generation and collection in p-n junctions excited with pulsed infrared lasers (1993)

The author examines optical absorption processes for applications of infrared lasers to the simulation of single-particle effects in silicon and GaAs, which require that the laser is focused to a small area on the device surface. The resulting charge generation is compared with charge generation from heavy ions. Charge funneling is reduced in silicon structures because of the lower charge density unless the LET (linear energy transfer) is above a threshold value. In both materials, the effective LET of a laser is inherently nonlinear because of nonlinear absorption at high intensities. These factors limit quantitative comparisons between lasers and heavy ions, and are increasingly important as devices are scaled to smaller dimensions.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Considerations for big data: Architecture and approach (2012)

The amount of data in our industry and the world is exploding. Data is being collected and stored at unprecedented rates. The challenge is not only to store and manage the vast volume of data (“big data”), but also to analyze and extract meaningful value from it. There are several approaches to collecting, storing, processing, and analyzing big data. The main focus of the paper is on unstructured data analysis. Unstructured data refers to information that either does not have a pre-defined data model or does not fit well into relational tables. Unstructured data is the fastest growing type of data, some example could be imagery, sensors, telemetry, video, documents, log files, and email data files. There are several techniques to address this problem space of unstructured analytics. The techniques share a common characteristics of scale-out, elasticity and high availability. MapReduce, in conjunction with the Hadoop Distributed File System (HDFS) and HBase database, as part of the Apache Hadoop project is a modern approach to analyze unstructured data. Hadoop clusters are an effective means of processing massive volumes of data, and can be improved with the right architectural approach.
Campylobacter pyloridis, gastritis, and peptic ulceration. (1986)

Campylobacter pyloridis is a spiral bacterium which was seen by histopathologists several years before it was cultured in 1982 in Perth, Western Australia. It has unique cellular fatty acids, predominantly tetradecanoic acid and cis-11, 12 methylene octadecanoic acid. It also has a unique ultrastructure which is different from that of other campylobacters. C pyloridis possesses a powerful urease enzyme and produces large amounts of extracellular catalase. Both these features may be important virulence factors, allowing it to occupy a protected niche in the stomach below the mucus layer but above the gastric mucosa. Specific lesions are found in the gastric mucosa, and ultrastructural studies show the presence of adherence pedestals identical with those found with enteropathogenic Escherichia coli of the intestine. Histological examination of gastric biopsy tissue has shown that C pyloridis is strongly associated with active chronic gastritis, when polymorphonuclear leucocytes are present, and is not found on normal mucosa except when a biopsy specimen from elsewhere in the stomach shows active chronic gastritis. When patients with symptoms caused by gastritis are identified dual antibacterial treatment, combining the action of bismuth in the stomach with a systemic antibiotic, can eradicate C pyloridis, with remission of symptoms and restoration of normal epithelial morphology. Most peptic ulcers relapse after modern acid reducing treatment, and antibacterial treatment may be beneficial in preventing relapse.
Alveolar Epithelial Fluid Transport Capacity in Reperfusion Lung Injury after Lung Transplantation (1999)

Reperfusion lung injury is an important cause of morbidity and mortality after orthotopic lung transplantation. The purpose of this study was to investigate the function of the alveolar epithelium in the setting of reperfusion lung injury. Simultaneous samples of pulmonary edema fluid and plasma were collected from eight patients with severe post-transplantation reperfusion edema. The edema fluid to plasma protein ratio was measured, an indicator of alveolar-capillary barrier permeability. The initial edema fluid to plasma protein ratio was > 0.75 in six of eight patients, confirming the presence of increased permeability of the alveolar-capillary barrier. Graft ischemic time was positively correlated with the degree of permeability (r = 0.77, p < 0.05). In four of six patients with serial samples, there was a high rate of alveolar fluid clearance (19 +/- 9%/h, mean +/- SD). Alveolar fluid clearance was calculated from serial samples in six patients. Intact alveolar fluid clearance correlated with less histologic injury, rapid resolution of hypoxemia, and more rapid resolution of radiographic infiltrates. The two patients with no net alveolar fluid clearance had persistent hypoxemia and more severe histologic injury. This study provides the first direct evidence that increased permeability to protein is the usual cause of reperfusion edema after lung transplantation, with longer ischemic times associated with greater permeability to protein in the transplanted lung. The high rates of alveolar fluid clearance indicate that the fluid transport capacity of the alveolar epithelium may be well preserved in the allograft despite reperfusion lung injury. The ability to reabsorb fluid from the alveolar space was a marker of less severe reperfusion injury, whereas the degree of alveolar-capillary barrier permeability to protein was not. Measurement of alveolar fluid clearance may be useful to assess the severity of reperfusion lung injury and to predict outcome when pulmonary edema develops after lung transplantation.

Deep Metric Learning for Person Re-identification (2014)

Various hand-crafted features and metric learning methods prevail in the field of person re-identification. Compared to these methods, this paper proposes a more general way that can learn a similarity metric from image pixels directly. By using a "siamese" deep neural network, the proposed method can jointly learn the color feature, texture feature and metric in a unified framework. The network has a symmetry structure with two sub-networks which are connected by a cosine layer. Each sub network includes two convolutional layers and a full connected layer. To deal with the big variations of person images, binomial deviance is used to evaluate the cost between similarities and labels, which is proved to be robust to outliers. Experiments on VIPeR illustrate the superior performance of our method and a cross database experiment also shows its good generalization.
Soluble HLA-G protein secreted by allo-specific CD4<sup>+</sup>T cells suppresses the allo-proliferative response: A CD4<sup>+</sup>T cell regulatory mechanism (2001)

We recently reported that the nonclassical HLA class I molecule HLA-G was expressed in the endomyocardial biopsies and sera of 16% of heart transplant patients studied. The aim of the present report is to identify cells that may be responsible for HLA-G protein expression during the allogeneic reaction. Carrying out mixed lymphocyte cultures in which the responder cell population was depleted either in CD4(+) or CD8(+) T cells, we found that soluble HLA-G5 protein but not the membrane-bound HLA-G isoform was secreted by allo-specific CD4(+) T cells from the responder population, which suppressed the allogeneic proliferative T cell response. This inhibition may be reversed by adding the anti-HLA-G 87G antibody to a mixed lymphocyte culture. That may indicate a previously uncharacterized regulatory mechanism of CD4(+) T cell proliferative response.
Oxidative stress and antioxidant status in type 1 diabetes mellitus (2002)

In spite of lower total antioxidant defence, our results do not support the oxidative stress hypothesis for type 1 diabetes mellitus. The higher tocopherol levels suggest that no vitamin E supplementation is necessary for subjects with type 1 diabetes mellitus.
<title>Instrumentation Of A Variable Angle Scatterometer (VAS)</title> (1983)

The problem of light scatter from optical surfaces is amplified to a critical level for the optics used in the Ring Laser Gyro (RLG). This has led to the development of a scatterometer at the RLG Lab, Wright-Patterson AFB, which can detect low level light scatter from the high quality optics used in RLG's, without first overcoating with metals. A helium-neon laser is used to illuminate a 0.5 mm diameter spot on the surface of the test part. The incident angle can be varied from 0 to 90 degrees, and the test piece can be maneuvered with five degrees of freedom, four of which are computer controlled. Scatter measurements are made with a photomultiplier detection system which can easily measure down to 10 parts per billion per steradian. The computer can analyze and plot the results very quickly and accurately for further interpretation.
Role of IL-17 and Th17 Cells in Liver Diseases (2010)

Unbalanced Th1/Th2 T-cell responses in the liver are a characteristic of hepatic inflammation and subsequent liver fibrosis. The recently discovered Th17 cells, a subtype of CD4(+) T-helper cells mainly producing IL-17 and IL-22, have initially been linked to host defense against infections and to autoimmunity. Their preferred differentiation upon TGFβ and IL-6, two cytokines abundantly present in injured liver, makes a contribution of Th17 cells to hepatic inflammation very likely. Indeed, initial studies in humans revealed activated Th17 cells and Th17-related cytokines in various liver diseases. However, functional experiments in mouse models are not fully conclusive at present, and the pathogenic contribution of Th17 cells to liver inflammation might vary upon the disease etiology, for example, between infectious and autoimmune disorders. Understanding the chemokines and chemokine receptors promoting hepatic Th17 cell recruitment (possibly CCR6 or CCR4) might reveal new therapeutic targets interfering with Th17 migration or differentiation in liver disease.

Cloning, sequencing and overexpression of the gene for prokaryotic factor EF-P involved in peptide bond synthesis (1991)

A soluble protein EF-P (elongation factor P) from Escherichia coli has been purified and shown to stimulate efficient translation and peptide-bond synthesis on native or reconstituted 70S ribosomes in vitro. Based on the partial amino acid sequence of EFP, 18- and 24-nucleotide DNA probes were synthesized and used to screen λ phage clones from the Kohara Gene Bank. The entire EF-P gene was detected on λ clone #650 which contains sequences from the 94 minute region of the E.coli genome. Two DNA fragments, 3.0 and 0.78 kilobases in length encompassing the gene, were isolated and cloned into pUC18 and pUC19. Partially purified extracts from cells transformed with these plasmids overrepresented a protein which co-migrates with EF-P upon SDS polyacrylamide gel electrophoresis, and also exhibited increased EF-P mediated peptide-bond synthetic activity. Based on DNA sequence analysis of this gene, the EF-P protein consists of 187 amino acids with a calculated molecular weight of 20,447. The sequence and chromosomal location of EF-P establishes it as a unique gene product.
Collaborative Driving System Using Teamwork for Platoon Formations (2005)

Collaborative driving is a growing domain of Intelligent Transportation Systems (ITS) that makes use of communications to autonomously guide cooperative vehicles on an Automated Highway System (AHS). In this paper, we address this issue by using a platoon of cars considered as more or less autonomous software agents. To achieve this, we propose a hierarchical architecture based on three layers (Guidance layer, Management layer and Traffic Control layer), which can be used to develop coordination models for centralized platoons (where a head vehicle-agent coordinates other vehicle-agents by applying its coordination rule) and decentralized platoons (where the platoon is considered as a team of vehicle-agents trying to maintain the platoon). The latter decentralized model mainly considers a software agent teamwork model using architectures like STEAM. These different coordination models will be compared using results on preliminary simulation scenarios, to provide arguments for and against each approach.
p53 Family: Role of Protein Isoforms in Human Cancer (2012)

TP53, TP63, and TP73 genes comprise the p53 family. Each gene produces protein isoforms through multiple mechanisms including extensive alternative mRNA splicing. Accumulating evidence shows that these isoforms play a critical role in the regulation of many biological processes in normal cells. Their abnormal expression contributes to tumorigenesis and has a profound effect on tumor response to curative therapy. This paper is an overview of isoform diversity in the p53 family and its role in cancer.
Considering the Importance of User Profiles in Interface Design (2010)

Human-computer interaction (HCI) is an interdisciplinary research area which concerns the study of interaction between humans (operators as users) and computers. A widely used definition interprets this concept as "a discipline concerned with the design, evaluation and implementation of interactive computing systems for human use and with the study of major phenomena surrounding them" (ACM SIGCHI, 1992). The reason for stating 'interdisciplinary' as the nature of HCI is the involvement of different disciplines contributing to HCI. Computer science is not the only discipline contributing to HCI; other disciplines, such as cognitive psychology, human factors, engineering, design, social and organizational psychology are also considered important and relevant. In the past for many years, a comprehensive range of research and studies concerning different aspects of HCI has been conducted or implemented. These studies are diverse, and include, for instance, dialogue techniques, gestural analysis and multimodal interfaces, computer graphics, computational linguistics, spatial cognition, robot navigation and wayfinding, input styles or devices, and monitor screens etc. However, the ultimate goal of the studies is to contribute to improving the interaction between humans and computer systems by endowing technical systems with higher usability and satisfaction. Facilitating the mutual interaction by presenting information on the status of the computer systems, a user interface normally works as a kind of communication platform or bridge between human beings and computers during the interaction. However, humans work as users operating or controlling the system by processing and interpreting the information. How to design interfaces that assist users in task performance in an optimal manner during interactions is a major challenge for all design engineers. When users interact with computer systems, many factors can influence overall performance. These factors cover various issues from the user side, task side, technical system side, and working environment/context side. Recently, from the perspective of human factors engineering, Osvalder & Ulfvengren (2009) have proposed performance-shaping factors (PSFs) as a generic name for those different influential factors. Furthermore, they have classified the PSFs into three categories: internal factors, external factors and stressors. The internal factors refer to physical and mental conditions that are either inbuilt or brought by humans as operators, such as age, vision,
