Exploring orthostatic hypotension in patients with multiple system atrophy by a non-invasive cardiac output system

Objective: To detect early subclinical signs of autonomic dysfunction in the cardiovascular system and explore the mechanism of orthostatic hypotension (OH) in patients with multiple system atrophy (MSA). Methods: Eighteen male patients with possible MSA and 10 healthy men were recruited. The hemodynamic responses to head-up tilt and tilt-reversal were studied by an electrically-powered tilt table and a non-invasive cardiac output measurement (NICOM) system. Results: At supine, there was no signifi cant difference in blood pressure, heart rate (HR), stroke volume, cardiac output and total peripheral resistance between MSA patients and healthy controls. During tilting upright, OH developed in 5 MSA patients, with a 23.7±4.8 mmHg drop in systolic blood pressure. Patients with OH were older and exhibited higher scores in unifi ed Multiple System Atrophy Rating Scale part I than patients without OH. The stroke volume, cardiac output and total peripheral resistance did not differ between groups. The controls had the most signifi cant HR elevation (6.5±2.5 bpm) during tiltup, followed by patients without OH (2.8±1.6 bpm) and those with OH (-0.2±2.2 bpm). A similar trend of HR decrease was observed during return to supine posture. The process of tilt-reversal altered HR more signifi cantly than head-up tilt in controls (8.0±2.9�! vs 6.5±2.5 bpm; P=0.031) and patients without OH (4.2±2.1�! vs 2.8±1.6�! bpm; P=0.032), but not in patients with OH (1.2±1.5 vs -0.2±2.2 bpm; P=0.380). Conclusions: The HR change during postural challenge showed signifi cant difference between MSA patients and healthy controls. Impaired HR responsiveness contributed to OH in MSA. Monitoring HR during the tilt table test may be a practical and useful method to detect early autonomic dysfunction in patients with MSA.
Key exchange in elliptic curve cryptography based on the decomposition problem

In this paper, we presented a new key exchange method based on decomposition problem for elliptic curve cryptography. We showed that our key exchange method was not only an alternative method for designing keys in cryptography, but it also has improved security condition from the previous key exchange based on decomposition problem over non-commutative groups. We proposed elliptic an curve cryptography to be the new platform for our key exchange protocol and showed how it was implemented. The security of our protocol was based on discrete logarithm problem, which was not infeasible and strictly difficult to retrieve in elliptic curve cryptography without any prior knowledge.
Diversity of the Luciferin Binding Protein Gene in Bioluminescent Dinoflagellates – Insights from a New Gene in Noctiluca scintillans and Sequences from Gonyaulacoid Genera

Dinoflagellate bioluminescence systems operate with or without a luciferin binding protein, representing two distinct modes of light production. However, the distribution, diversity, and evolution of the luciferin binding protein gene within bioluminescent dinoflagellates are not well known. We used PCR to detect and partially sequence this gene from the heterotrophic dinoflagellate Noctiluca scintillans and a group of ecologically important gonyaulacoid species. We report an additional luciferin binding protein gene in N. scintillans which is not attached to luciferase, further to its typical combined bioluminescence gene. This supports the hypothesis that a profound re‐organization of the bioluminescence system has taken place in this organism. We also show that the luciferin binding protein gene is present in the genera Ceratocorys, Gonyaulax, and Protoceratium, and is prevalent in bioluminescent species of Alexandrium. Therefore, this gene is an integral component of the standard molecular bioluminescence machinery in dinoflagellates. Nucleotide sequences showed high within‐strain variation among gene copies, revealing a highly diverse gene family comprising multiple gene types in some organisms. Phylogenetic analyses showed that, in some species, the evolution of the luciferin binding protein gene was different from the organism's general phylogenies, highlighting the complex evolutionary history of dinoflagellate bioluminescence systems.
A NEW THEORY OF HEALTH BEHAVIOR WITH IMPLICATIONS FOR PREVENTIVE INTERVENTIONS

Some theories of health behavior focus on proximal cognitive predictors of behavior, some focus on expectancy-value formulations, some focus on social support and bonding processes, some focus on social learning processes, and some point toward personality and intrapersonal processes. Very few extant theories of health behavior incorporate several of these viewpoints, and those that do are limited in various ways. We propose a new comprehensive theory that integrates constructs from all previous theories. Triadic influence theory includes seven “tiers” of “causes” of behavior that range from very proximal to distal to ultimate, and three “streams of influence” that flow through the seven “tiers”: (I) culturalenvironmental influences on knowledge and values, influencing attitudes, (2) social situation-context influences on social bonding and social learning, influencing social normative beliefs, and (3) intrapersonal influences on self determination/control and social skills, leading to self-efficacy. In addition to the direct influences of these streams, there are important inter-stream effects and influences that flow between tiers. The theory is intended to account for Advances in Medical Sociology, Volume 4, psgrq 19-44. Copyright Q 1994 by JAI l’kss Inc. All rights of reproduction in any form reserved.

A Qualitative and Quantitative Assay for Cells Lacking Postconfluence Inhibition of Cell Division : Characterization of This Phenotype in Carcinogen-treated Syrian Hamster Embryo Cells in Culture 1

We have developed a qualitative and quantitative assay system for detecting cells lacking postconfluence inhibition of cell division (contact insensitivity, CS~) in golden Syrian ham ster embryo cells in culture by measuring the number of cells able to form colonies on a lethally irradiated, confluent monolayer of a contact-sensitive established cell line. A subpopulation in normal low-passage cultures of golden Syrian hamster embryo cells temporarily exhibits this CS~ phenotype at very low frequency (~4 x 10~3) but quickly loses the property within a few passages in vitro. This phenotype is invariably exhibited by various tumorigenic cell lines at very high fre quency (7 to 50 x 10~2) and appears to correlate with the anchorage-independent growth phenotype. The temporal ac quisition of the CS~ phenotype by tertiary-passage golden Syrian hamster embryo cells following exposure to A/-methylA/'-nitro-A/-nitrosoguanidine was examined. Cells with a stably heritable CS~ phenotype are detected after approximately 20 posttreatment population doublings. In contrast, anchorageindependent cells are not detected until 35 to 95 posttreatment population doublings. These CS~ cells appear to be preneoplastic cells, since clonally isolated CS~ cells did not exhibit anchorage-independent growth until after further passaging in vitro. The results suggest that acquisition of the CS~ phenotype represents an early stage in neoplastic progression.
Oxidative and nitrative modifications of enkephalins by reactive nitrogen species

The interaction of Leucine-enkephalin (Leu-enkephalin) with reactive nitrogen species has been investigated. Reactive nitrogen species are capable of nitrating and oxidizing Leu-enkephalin. HPLC analysis shows the formation of two major enkephalin derivatives by peroxynitrite. The tyrosine amino-terminal residue of Leu-enkephalin is converted either to 3-nitrotyrosine thus producing nitroenkephalin and to dityrosine by dimerization with the production of an enkephalin dimer. The evidence of the formation of the nitroenkephalin and of the enkephalin dimer—dienkephalin—was achieved by electrospray ionisation mass spectrometry. In addition to peroxynitrite, the methylene blue photosensitized oxidation of enkephalin in the presence of nitrite leads to the formation of the nitrated peptide. Moreover, the nitropeptide can be also obtained by peroxidase-generated nitrogen reactive species.
Effects of Grip-Force, Contact, and Acceleration Feedback on a Teleoperated Pick-and-Place Task

The multifaceted human sense of touch is fundamental to direct manipulation, but technical challenges prevent most teleoperation systems from providing even a single modality of haptic feedback, such as force feedback. This paper postulates that ungrounded grip-force, fingertip-contact-and-pressure, and high-frequency acceleration haptic feedback will improve human performance of a teleoperated pick-and-place task. Thirty subjects used a teleoperation system consisting of a haptic device worn on the subject's right hand, a remote PR2 humanoid robot, and a Vicon motion capture system to move an object to a target location. Each subject completed the pick-and-place task 10 times under each of the eight haptic conditions obtained by turning on and off grip-force feedback, contact feedback, and acceleration feedback. To understand how object stiffness affects the utility of the feedback, half of the subjects completed the task with a flexible plastic cup, and the others used a rigid plastic block. The results indicate that the addition of grip-force feedback with gain switching enables subjects to hold both the flexible and rigid objects more stably, and it also allowed subjects who manipulated the rigid block to hold the object more delicately and to better control the motion of the remote robot's hand. Contact feedback improved the ability of subjects who manipulated the flexible cup to move the robot's arm in space, but it deteriorated this ability for subjects who manipulated the rigid block. Contact feedback also caused subjects to hold the flexible cup less stably, but the rigid block more securely. Finally, adding acceleration feedback slightly improved the subject's performance when setting the object down, as originally hypothesized; interestingly, it also allowed subjects to feel vibrations produced by the robot's motion, causing them to be more careful when completing the task. This study supports the utility of grip-force and high-frequency acceleration feedback in teleoperation systems and motivates further improvements to fingertip-contact-and-pressure feedback.
The Seven Levels of Intimacy: The Art of Loving and the Joy of Being Loved

Kelly presents seven levels through which we are able to experience intimacy, taking us from the first level 'The Intimacy of Cliche' to the seventh, 'The intimacy of Legitimate Needs. ' Throughout he tracks our progression as we share more and more about ourselves with others, while safe-guarding us from mistakes that can be made at each stage. Kelly explores each level in depth by revealing the interactions that take place, the physical life of each level and the potential for finding our 'best-self' throughout. The book includes strategies for self-acceptance, even when exploring the worst within us, as we shed old ideas and behaviors and move to greater levels of intimacy.
Nest: A Network Simulation Prototyping Testbed

This paper describes Nest, a graphical environment for distributed networked systems simulation and rapid-prototyping. Nest users can develop and test distributed systems and protocols (from crude models to actual system code) within simulated network scenarios. Nest represents an environment-based approach to simulation. Users view Nest as an extension of their standard Unix environment. Nest offers the generality of language-based simulation techniques and the efficiencies of model-based techniques. Users interact with Nest through standardized graphical interfaces. Nest permits the users to modify and reconfigure the simulation during execution. Thus, it is possible to study the dynamic response of a distributed system to failures or burst-loads. Nest is organized as a simulation server, responsible for execution of complex simulation scenarios, and client monitors responsible for simulation control. The client/server model permits distribution of Nest over a network environment. This permits migration of simulations to powerful remote computational servers as well as development of a shared multi-site simulation/integration testbed. Nest is portable and extensible. It has been ported to virtually all Unix variants and distributed since 1987 to over 150 sites worldwide. It has been used in scores of studies ranging from communication protocols, to distributed databases and operating systems as well as distributed manufacturing systems.
Embryologic origin of various epithelial cell types in the thyroid gland of the rat

Ventral pharyngeal outpocketings and ultimobranchial out‐pocketings from the 14‐day‐old fetus of the Fischer rat were isolated before they fused to form thyroid glands. The outpocketings were implanted into different kidney capsules of adult male Fischer rats, and were allowed to grow for several months. Transplants were then excised and examined by electron microscopy. The ultimobranchial outpocketing gave rise to two types of follicles. One contained ciliated cells, cells with an abundant agranular reticulum, U cells with basal hemidesmosomes, and two types of cells with secretory vesicles. The other contained C cells separated from the follicular lumen by a single flat fiber‐con‐taining cell. The ventral outpocketing formed typical thyroid epithelium making up the usual thyroid follicles differing from follicles in the thyroid in situ by the absence of C cells. These follicles were functional as determined by autoradio‐graphic studies with 125I but differed from thyroid follicles in situ with respect to size distribution. The results suggest that (1) in the adult thyroid gland the C cell in the usual follicle is an ultimobranchial contribution and (2) the so‐called ultimobranchial follicle is ultimobranchial in origin but that the typical thyroid epithelium in mixed follicles of U cells and typical thyroid epithelium is a ventral contribution. The reason for the absence in the thyroid gland in situ of the variety of other cell types observed in ultimobranchial transplants is unknown.
Investigating the One-on-One Master-Apprentice Relationship: A Case Study in Traditional Craft Apprenticeship

Investigating the One-on-One Master-Apprentice Relationship: A Case Study in Traditional Craft Apprenticeship Isaac W. Calvert Department of Instructional Psychology and Technology, BYU Doctor of Philosophy Governments around the world are calling for a revival of apprenticeship on a large scale, emphasizing the value of the one-on-one, human interaction between master and apprentice and the teaching involved in that interaction. Although a broader historical view of apprenticeship shares these ideas, certain prominent threads within recent educational research have done a great deal to deemphasize them. Some go so far as to overlook the master-apprentice relationship altogether, assert that masters simply do not exist, and claim that apprenticeship learning happens without any teaching at all. In response to these claims, the researcher took part in an autoethnographic case study, participating himself in a two-year apprenticeship under a master violinmaker. Analysis from the case suggests that the one-on-one master-apprentice relationship plays a key role in apprenticeship learning, that mastery is embodied in individuals rather than in communities alone, and that a master’s teaching does in fact make a difference to an apprentice’s learning.
Data Block Partitioning for Recovering Stuck-at Faults in PCMs

Main burdens to the DRAM scalability are leakage and charge storage restrictions. Phase Change Memory (PCM) is being known as a promising candidate for the replacement of DRAM among competitive non-volatile memories. However, this memory suffers from low cell reliability due to limited write endurance. This problem can lead to some memory cells permanently stuck at either '0' or '1'. Therefore, a robust error recovery scheme is needed to overcome this problem and recover from hard errors. State-of-the-art solutions apply error correction and recovery techniques at inter- line or intra-line level. Precisely, they can improve PCM endurance either by remapping failed lines to spares (in inter-line level schemes) or by using data-block partitioning and bit- inversion scheme (in intra-line level schemes). Although techniques of the latter type are effective, proper partitioning of data blocks and spreading out faults across different groups are required. In this paper, we propose and evaluate a novel intra-line level scheme that statically partition a data-block into some groups and efficiently recover multi-bit stuck-at faults per partition. This method benefits from the advantage of a simple shifting mechanism in order to increase the chance of storing data in presence of failed cells. Evaluation results for multi- threaded workloads show enhancement in the number of recoverable failures and improvement of lifetime over existing techniques.
Condom Use Among Sexually Active Rural High School Adolescents Personal, Environmental, and Behavioral Predictors

Adolescents who engage in unprotected intercourse are at risk of pregnancy and sexually transmitted infection (STI). Although adolescents in rural areas participate in levels of sexual risk taking similar to that of nonrural youth, few data are available identifying factors that influence condom use among rural adolescents. The purpose of this study is to determine the predictive value of selected personal, environmental, and behavioral factors for condom use among rural adolescents in grades 9–12. A cross-sectional survey was conducted among sexually active youth (N = 613), ages 14–19, in three rural school districts in the Northeast. Using logistic regression, identified predictors for condom use include personal standards (odds ratio [OR] = 2.45; confidence interval [CI]: [2.39, 6.47]), condom use goals (OR = 1.32; CI [1.21, 1.45]), condom use at first intercourse (OR = 3.93; CI [2.39, 6.47]) and male gender. School nurses are encouraged to incorporate identified predictors of condom use when considering interventions promoting safer sexual behaviors among rural youth.
Tamper Detection of Relational Database Based on SVR Predictive Difference

Database authentication verifies valuable content from illicit copying, illegal redistribution and maliciously tamper while it is to be sold or be outsourced to un-trusted parties. This paper exploits the digital watermarking technology for guaranteeing the database integrity underlying distortion free of database content. The proposed scheme employs SVR predictive function to obtain characteristic of the database and uses Huffman coding to encode the characteristic for compressing important payload information. In detection phase, minor and necessary additional payload information of the database is used to accomplish tampering detection.
Research info the application of split-phase coupling array integration inductance in four-phase voltage regulator module

To increase the output dynamic response and decrease the stable ripple of VRM, With multi-core combination, a split-phase coupling array integration inductance (short for SCAII) is applied in the four-phase VRM. Without considering the impact of leakage magnetic flux, the effect of SCAIIpsilas parameters is analyzed on the performance of VRM. The SCAIIpsilas complanation structure, is given and using electromagnetic field finite element software complanation SCAII VRM is analyzed. Using circuit simulation software the SCAII is compared with the separation magnetics. The simulation results show the correctness of the theory and experimental results showe that four-phase SCAII VRM has preferable dynamic effectiveness.
State of Charge Estimation Using the Extended Kalman Filter for Battery Management Systems Based on the ARX Battery Model

State of charge (SOC) is a critical factor to guarantee that a battery system is operating in a safe and reliable manner. Many uncertainties and noises, such as fluctuating current, sensor measurement accuracy and bias, temperature effects, calibration errors or even sensor failure, etc. pose a challenge to the accurate estimation of SOC in real applications. This paper adds two contributions to the existing literature. First, the auto regressive exogenous (ARX) model is proposed here to simulate the battery nonlinear dynamics. Due to its discrete form and ease of implemention, this straightforward approach could be more suitable for real applications. Second, its order selection principle and parameter identification method is illustrated in detail in this paper. The hybrid pulse power characterization (HPPC) cycles are implemented on the 60AH LiFePO 4 battery module for the model identification and validation. Based on the proposed ARX model, SOC estimation is pursued using the extended Kalman filter. Evaluation of the adaptability of the battery models and robustness of the SOC estimation algorithm are also verified. The results indicate that the SOC estimation method using the Kalman filter based on the ARX model shows great performance. It increases the model output voltage accuracy, thereby having the potential to be used in real applications, such as EVs and HEVs.
SAR image target recognition via deep Bayesian generative network

In this letter, a novel deep-leaming-based feature selection method based on Poisson Gamma Belief Network (PGBN), is proposed to extract multi-layer feature from SAR images data. As a deep Bayesian generative network, PGBN has the ability to extract a multilayer structured representation from the complex SAR images owing to the existence of Poisson likelihood and multilayer gamma hidden variables, at the same time the PGBN can be viewed as a deep non-negative matrix factorization model. Note that the PGBN model is an unsupervised deep generative network and it fails to make full use of the label information in training stage. Therefore, the NBPGBN model is further proposed to obtain a higher recognition performance and training efficiency based on Naïve Bayes rule. The experimental results on MSTAR dataset show that the feature extracted by this new approach has better structured information and perform better classification result compared with some related algorithms.
Token-to-token variability and anticipatory coarticulation as indicators of maturity of speech motor control in 4-year-old children

Children’s gestures do not appear to be executed with the same dexterity as adults’. Studies of arm movements have shown that young children’s gestures are less accurate, more variable and slower than those of adults. This difference in behavior can be explained by a lack of experience with the sensory consequences of motor acts and still-developing forward models for the control of those acts. The hypothesis of immature and incomplete sensori-motor representations for speech in 4-year-old native speakers of Canadian French is addressed here through the analysis of ultrasound recordings of tongue contour kinematics and the speech signal from a corpus of isolated vowels and vowel-consonant-vowel sequences. Special attention is devoted to the analysis of vowel variability from two perspectives. Variability across repetitions in a single context provides information about the accuracy of the control. Contextual variability provides insights into the planning process as reflected in anticipatory coarticulatio.
