A direct field-oriented controller for induction motor drives using tapped stator windings (1990)

The implementation of a direct method of field orientation that requires little knowledge of machine parameters and uses only readily measurable quantities is discussed. The system uses tapped stator windings to measure the air-gap flux. The signals from the tapped windings are also used in a flux-regulation loop. A speed controller is implemented using the ripples created in the tapped windings by the motion of the rotor slots through the flux for speed information.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Effect of Oral Beta Interferon on Subsequent Immune Responsiveness (1996)

Oral administration of myelin antigens reduces the incidence and severity of EAE in rat and mouse models and decreases the frequency of MBP-reactive cells and the frequency of attacks in some patients with multiple sclerosis. Low-dose oral tolerance has been shown to be mediated by Th2-type regulatory cells that secrete TGFbeta and IL-4/IL-10. Adjuvants and cytokines may modulate oral tolerance. The addition of betaIFN to the experimental therapy regimen, either orally or by intraperitoneal injection, has been shown to enhance the suppressive effects of oral myelin antigens when either are fed the suboptimal dosing regimen to suppress EAE. The current studies were conducted to elucidate the mechanism of the observed in vivo synergy of betaIFN and antigen feeding. Analysis of the in vitro proliferative response and cytokine production by lymphocytes from fed animals in response to specific antigen in culture shows that the synergistic effect may be related to both independent suppression of the immune response by oral betaIFN and enhanced production of TGFbeta and IL-4/IL-10. There was an unexpected increase in the production of gammaIFN by lymphocytes in vitro after three doses of oral betaIFN in vivo. These observations have important implications for the use of cytokines to modulate oral tolerance.
Exercise Training Reduces Coronary Risk and Effectively Rehabilitates Hemodialysis Patients (1986)

This study examines the effects of 12 months of endurance exercise training (cycling, walking and jogging) on lipid profiles, glucose metabolism, blood pressure, anemia and psychological function in 14 hemodialysis patients. Maximal aerobic capacity (VO2max) increased 18% in the exercisers (p less than 0.01), but did not change in 11 controls. This was associated with a reduction in depression, a decrease in dosages of antihypertensive medications, a significant increase in hematocrit and hemoglobin levels (red cell mass rose, plasma volume did not change), a decrease in plasma triglyceride by 23% (p less than 0.05) and an increase in high-density lipoprotein cholesterol (HDL-C) levels by 21% (p less than 0.01) (both HDL-C and triglyceride levels worsened in the sedentary controls), and an 18% increase in glucose disappearance rates (p less than 0.05) in spite of a 52% decrease in fasting insulin levels (p less than 0.01), suggesting that insulin sensitivity improved. These results demonstrate that some of the complications present in hemodialysis patients may be caused by their sedentary life-style, rather than endstage renal disease itself. This suggests that rehabilitation through exercise is possible for these patients. By reducing coronary risk factors in hemodialysis patients, exercise training may also decrease their heightened morbidity and mortality from atherosclerotic complications. These possibilities need to be examined in a longitudinal study.
Expression of <i>RPS4</i> in tobacco induces an AvrRps4‐independent HR that requires EDS1, SGT1 and HSP90 (2004)

The Arabidopsis RPS4 gene belongs to the Toll/interleukin-1 receptor/nucleotide-binding site/leucine-rich repeat (TIR-NB-LRR) class of plant resistance (R) genes. It confers resistance to Pseudomonas syringae carrying the avirulence gene avrRps4. Transient expression of genomic RPS4 driven by the 35S promoter in tobacco leaves induces an AvrRps4-independent hypersensitive response (HR). The same phenotype is seen after expression of a full-length RPS4 cDNA. This indicates that alternative splicing of RPS4 is not involved in this HR. The extent of HR is correlated with RPS4 protein levels. Deletion analyses of RPS4 domains show the TIR domain is required for the HR phenotype. Mutations in the P-loop motif of the NB domain abolish the HR. Using virus-induced gene silencing, we found that the cell death resulting from RPS4 expression is dependent on the three plant signalling components EDS1, SGT1 and HSP90. All these data suggest that heterologous expression of an R gene can result in activation of cell death even in the absence of its cognate avirulence product, and provides a system for studying the RPS4 domains required for HR.
Serologic and histopathologic study of<i>Chlamydia pneumoniae</i>infection in atherosclerosis: a possible pathogenetic mechanism of atherosclerosis induced by<i>Chlamydia pneumoniae</i> (2000)

Chronic infection and inflammation have recently been implicated as important etiologic agents for atherosclerosis in general and, in particular, ischemic heart disease. Several agents have been suggested as possible candidates for the chronic inflammation including cytomegalovirus, Helicobacter pylori and Chlamydia pneumoniae. We hypothesized that a vascular infection with C. pneumoniae may induce a chronic inflammatory reaction in the host vascular tissue and activated inflammatory cells may express inflammatory mediators such as cyclooxygenase-2 (COX-2) and matrix metalloproteinases (MMPs). At first, we evaluated the relationship between C. pneumoniae infection and atherosclerosis indirectly by serologic study, and then, to confirm our hypothesis, we performed an immunohistochemical study of atherosclerotic plaques. The seropositive rate of anti-Chlamydia pneumoniae IgG was higher in the disease group (Group I, 59.8%, n = 254) than in the negative control group (Group III, 47.4%, n = 97) (p = 0.041), but the anti-Chlamydia pneumoniae IgA was not different in seropositivity between the two groups (Group I, 64.6%; Group III, 57.7%). The simultaneous seropositive rates of both IgG and IgA were 56.7% in Group I and 43.3% in Group III (p = 0.033). In subgroups without the conventional risk factors of atherosclerosis, these findings were more prominent. Furthermore, we performed immunohistochemical staining on the atherosclerotic aortic tissues obtained from patients that were seropositive to C. pneumoniae (n = 5), by using antibodies to C. pneumoniae, COX-2, and MMP-9. The immunoreactivity for COX-2 and MMP-9 increased in the atherosclerotic plaques itself, predominantly in the surrounding area of immunoreactive C. pneumoniae. These findings support our hypothesis and C. pneumoniae may participate in a pathogenetic mechanism for atherogenesis or progression of atherosclerosis. The present study may open a promising perspective concerning future therapeutic trials of chronic inflammation related atherogenesis under pathophysiological conditions.
A two-level source address spoofing prevention based on automatic signature and verification mechanism (2008)

IP source address spoofing is used by DDoS and DrDoS attacks in the Internet. This paper presents a signature-and-verification based IP spoofing prevention method, automatic peer-to-peer based anti-spoofing method (APPA). APPA has two levels: intra-AS (autonomous system) level and inter-AS level. In the intra-AS level, the end host tags a one-time key into each outgoing packet and the gateway at the AS border verifies the key. In inter-AS level, the gateway at the AS border tags a periodically changed key into the leaving packet and the gateway at border of the destination AS verifies and removes the key. The most prominent characteristic of APPA is the automatically synchronizing state-machine, which is used to update keys automatically and effectively. The benefits of APPA are: (1) preventing IP address spoofing strictly, end systems canpsilat even spoof addresses in the same AS or subnet, (2) providing very low running and management costs, (3) supporting anti-replay attacks and incremental deployment.
INHIBITION OF RAT MIXED LYMPHOCYTE PANCREATIC ISLET CULTURES WITH ANTI-Ia IMMUNOTOXIN (1986)

Studies reported here indicate that an anti-Ia immunotoxin can eliminate the allostimulatory subpopulation of cells present within the islets of Langerhans without damaging the hormone-secreting cells. Such studies made use of an in vitro correlate of transplantation rejection, the mixed lymphocyte islet cell (MLIC) reaction. Using the MLIC, it was demonstrated that an anti-Ia immunotoxin removed cells capable of stimulating the MLIC in a dose-dependent fashion without altering the hormone-secreting functions of the remaining cells when challenged with glucose and theophylline. These studies suggest the feasibility of using such anti-Ia immunotoxins in islet allograft transplantation models to circumvent problems inherent in complement-mediated cytotoxicity, a previously documented effective form of inducing islet allotransplantation tolerance.
Flame Retardants, Phosphorus (2001)

Abstract One of the principal classes of flame retardants for plastics and textiles is that of phosphorus, phosphorus‐nitrogen, and phosphorus‐halogen compounds. These flame retardants are also used for wood and paper. The mechanisms of action, which may be in the condensed or vapor phase or in both, are presented. The interactions with other flame retardants are discussed. Commercial phosphorus‐based flame retardants include some inorganic compounds as well as both additive and reactive organic phosphorus systems. These materials range from simple salts to oligomeric compounds and encompass both liquids and solids. Some commercial products are pure compounds. Others are mixtures. The various compounds, corresponding structures, and specific uses are given. The toxicity of these products is discussed.
Nimodipine, a voltage-sensitive calcium channel antagonist, fails to ameliorate light-induced retinal degeneration in rat. (1991)

A recent study demonstrated the amelioration of light-induced photoreceptor degeneration by flunarizine and suggested that the protective effect achieved by the drug may be due to the inhibition of inositol 1,4,5-trisphosphate-induced calcium release from intracellular stores or the inhibition of calcium entry through putative voltage-sensitive calcium channels. In the current study, we investigated the effect of nimodipine, a specific voltage-sensitive calcium channel blocker, in light-induced retinal degeneration to further define the factors involved in the retinal degenerative process. Morphological, morphometric, and biochemical results demonstrated that nimodipine was ineffective in ameliorating light-induced retinal degeneration, and implied that calcium entry through voltage-sensitive channels is unlikely to be involved in this disease process, and inositol 1,4,5-trisphosphate-induced calcium release from intracellular stores may play a dominant role in light-induced photoreceptor cell damage.
Enforcing Flexible Access Control in a Networked Policy Domain (2007)

Significant progress toward general acceptance of applying mandatory access control to systems has been made recently. Security Enhanced Linux (SELinux), in particular, has been enabled by default in some Linux distributions for several years. However, current SELinux deployments only effectively control a single system. Inter-system and remote resource access control capabilities are starting to appear in SELinux, but extending policy management capabilities to cover these networked systems remains an open problem. This paper discusses issues that must be addressed to support security policies distributed across a network, including policy development changes needed to be able to express a coherent security policy for a network of systems, managing the distribution of a multi-system policy, and synchronizing policy updates, and presents a distributed policy management architecture.

Rheological Abnormalities of Erythrocyte Deformability and Increased Glycosylation of Hemoglobin in the Nephrotic Syndrome (1987)

This report is an attempt to gain more complete knowledge of the causes of the tendency to thrombosis in the nephrotic syndrome. Our purpose was to detect some rheological abnormalities in a group of nephrotic patients having normal renal function. Plasma and blood viscosity, erythrocyte filtration flow (EFF) and some indices of the carbohydrate metabolic state (glycosylated hemoglobin A1c; HbA1c, fasting glycemia and oral glucose tolerance test) were investigated in 10 patients with newly diagnosed primary nephrotic syndrome and 10 healthy subjects. EFF was determined in order to avoid variables depending upon plasma, white cells and hematocrit. The mean level of HbA1c was higher in the nephrotic group, in which we found 4 patients with impaired glucose tolerance according to the criteria of the National Diabetes Data Group. EFF was lower in nephrotic patients than in controls and correlated inversely with HbA1c. These findings indicate that nephrotic patients have a reduced red cell deformability which seems to be related to the abnormal carbohydrate metabolism commonly observed in this syndrome.

Interactions between Volatile and Nonvolatile Coffee Components. 1. Screening of Nonvolatile Components (2005)

This study is the first of two publications that investigate the phenomena of coffee nonvolatiles interacting with coffee volatile compounds. The purpose was to identify which coffee nonvolatile(s) are responsible for the interactions observed between nonvolatile coffee brew constituents and thiols, sulfides, pyrroles, and diketones. The overall interaction of these compounds with coffee brews prepared with green coffee beans roasted at three different roasting levels (light, medium, and dark), purified nonvolatiles, and medium roasted coffee brew fractions (1% solids after 1 or 24 h) was measured using a headspace solid-phase microextraction technique. The dark roasted coffee brew was slightly more reactive toward the selected compounds than the light roasted coffee brew. Selected pure coffee constituents, such as caffeine, trigonelline, arabinogalactans, chlorogenic acid, and caffeic acid, showed few interactions with the coffee volatiles. Upon fractionation of medium roasted coffee brew by solid-phase extraction, dialysis, size exclusion chromatography, or anion exchange chromatography, characterization of each fraction, evaluation of the interactions with the aromas, and correlation between the chemical composition of the fractions and the magnitude of the interactions, the following general conclusions were drawn. (1) Low molecular weight and positively charged melanoidins present significant interactions. (2) Strong correlations were shown between the melanoidin and protein/peptide content, on one hand, and the extent of interactions, on the other hand (R = 0.83-0.98, depending on the volatile compound). (3) Chlorogenic acids and carbohydrates play a secondary role, because only weak correlations with the interactions were found in complex matrixes.
Phenomenological Analysis of Shock-Wave Propagation in Weakly Ionized Plasmas (1998)

Shock propagation into weakly ionized gases shows several features differing markedly from conventional, nonionized-gas shock structure. Phenomenological analysis of general macroscopic features of the previously observed plasma shock effects allows only two possible interpretations: existence of an energy (momentum) flux toward the wave precursor or volumetric energy release (exothermic phase transition) in the upstream portion of the wave (precursor) followed by reverse transition in the downstream portion of the wave. It is shown that known microscopic mechanisms are not capable of producing such a flux or energy release: Typical processes involving electrons, ions, and excited species do not couple strongly to neutral atoms and molecules, and there is not enough energy stored in these species because of the low ionization fraction. The theoretical basis for phase transitions in low-density, weakly ionized plasmas also is unknown. Analysis of the steady two-wave system created by either of the two effects raises a question as to whether the observed plasma shocks are stable objects. Another question is whether there exists phase transition within the plasma shock. It also remains unclear to what extent twodimensional thermal inhomogeneity effects contribute to the observed phenomena. Answering these fundamental questions requires additional experimental studies of the problem. p D d E E/N F h j k

Real time embedded sensor fusion for driver assistance (2005)

This paper details the design and implementation of an embedded real-time system to fuse data from two 77 GHz radars, three 24 GHz radars and a video lane detection system fitted to a vehicle to track the movement of other vehicles in the local environment. The system demonstrates excellent tracking of vehicles as they pass through regions covered by single and multiple sensors as well as regions with no sensor coverage where tracking continues despite no new measurements. Such a system facilitates future driver assistance functions such as lane change support and blind spot detection.
Effects of cooling somatosensory cortex on response properties of tactile cells in the superior colliculus (1986)

The corticotectal influences of somatosensory cortex were investigated by using reversible deactivation of cortex by cooling. More than half of the somatosensory superior colliculus (SC) cells studied exhibited a response depression (often not apparent qualitatively) or an elimination of responses to somatosensory stimuli during the period in which cortex was rendered inactive. Responses were restored to their initial levels by cortical rewarming. Hyperresponsiveness was never observed as a consequence of cortical cooling. Susceptibility to cooling-induced depression was not invariably linked to a specific cell type, location in the SC, or receptive-field size. Yet cells that had small receptive fields and were activated by hair displacement had the highest probability of being affected by this procedure. In some cells a contraction of the receptive field was induced by cortical cooling. This observation is consistent with previous experiments that showed that SC somatosensory receptive fields are constructed by the convergence of ascending and descending inputs and indicates that the responsiveness of specific receptive-field regions may depend on the functional integrity of cortex. Two cortical regions were found to produce cooling-induced effects in somatosensory SC cells: 1) SIV (and para-SIV), located in the anterior ectosylvian sulcus, and 2) the cortex within the rostral suprasylvian sulcus. These results indicate that somatosensory cortex, like visual cortex, plays a critical role in modulating the responses of SC cells. Apparently, the ability of both somatosensory and visual SC cells to code the presence of peripheral stimuli depends largely on the functional influences of their respective cortices. However, in contrast to previous observations on visual corticotectal influences, no specific receptive-field properties could be shown to be impressed on SC cells by somatosensory cortex.
Local and central circulatory responses to sustained contractions and the effect of free or restricted arterial inflow on post‐exercise hyperaemia (1967)

1. The cardiovascular responses to sustained contractions at tensions from 5 to 30% maximal voluntary contraction (MVC) have been examined. At 5 and 10% MVC blood pressure, heart rate and forearm blood flow all reached a steady state during the contraction; post-exercise hyperaemia did not show peak flows higher than those found during exercise. At tensions of 20 and 30% MVC, none of the measurements showed a steady state during the contractions, but increased steadily throughout the contraction; post-exercise hyperaemia characteristically showed peak flows in excess of any flow measured during contractions. The results obtained at a tension of 15% MVC did not show a steady-state during the contraction but the following hyperaemia showed a similar pattern to that seen at the lower tensions.2. Digital compression of the brachial artery after sustained handgrip contractions for periods of 3 or 6 min after the contraction ended resulted in only a small reduction, on average by 5-15%, of the post-exercise hyperaemia.3. Consideration of the evidence leads to the view that in physiological circumstances the post-exercise hyperaemia following sustained contractions bears a close relationship to the metabolism of the active muscles.
ROANS - intelligent simulation and programming system for robots and automated workcell (2002)

Computer is an essential tool for the design, animation, analysis and programming of robots and automated workcell. There are some general CAD products available for design, 3D animation and commercial presentation, but they are complex, run on workstations and require high capital expenditure. On the other hand, there are some special software which are unique PC based analytical and simulation programming systems (ROANS, SOMBAT, ROBCAD, KUSIM). The paper describes the ROANS software which is often used for the development of automated cells, kinematic and dynamic analysis, programming, simulation and monitoring, and communication with the robots.
