Phase-shifting interferometry using a two-dimensional regularized phase-tracking technique (1998)

Abstract Phase-shifting interferometry is the most used method whenever the optical stability of the interferometer remain high when several phase-shifted interferograms are taken. In this work we present a two-dimensional regularized phase-tracking (RPT) technique applied to demodulate multiple phase-shifted interferograms. The main advantage of this technique with reference to classical phase-shifting interferometry is its higher signal-to-noise rejection as well as a higher signal′s harmonics rejection. In the RPT technique the unwrapping process is implicit; so it is achieved simultaneously with the phase estimation process; then, no additional unwrapping process is required.
Isolation of O1 Serovars of <i>Vibrio cholerae</i> from Water by Serologically Specific Method (1980)

Vibrio cholerae bacteria of the serological variety O1 were consistently isolated from water samples by passing the water with added Tween 20 through columns packed with polystyrene beads coated with antibodies against the O1 antigenic determinants. The beads from the columns were washed, transferred to alkaline peptone broth, and incubated. The O1 serovars were isolated and identified by established procedures.
Advances and Perspectives in Cell-Specific Aptamers (2011)

Nucleic acid aptamers, generated by an in vitro selection procedure named SELEX (Systematic Evolution of Ligands by Exponential enrichment), have been popularly used in various biomedical implementations so far. An adaptation of the conventional SELEX practice to whole living cells was referred to as cell-SELEX, which is very promising in ample sophisticated analytical, therapeutic and diagnostic applications. The current review article would like to provide a survey of contemporary developments in cell-specific aptamers, including methodology, applications and optimization of cell-SELEX.
Application of AI technology to nuclear plant operations (1988)

In this paper, applications of Artificial Intelligence (AI) Technology to nuclear-power plant operation are reviewed. AI Technology is advancing rapidly and in the next five years is expected to enjoy widespread application to operation, maintenance, management and safety. Near term emphasis on a sensor validation, scheduling, alarm handling, and expert systems for procedural assistance. Ultimate applications are envisioned to culminate in autonomous control such as would be necessary for a power system in space, where automatic control actions are taken based upon reasoned conclusions regarding plant conditions, capability and control objectives.
Plasma losses through an adiabatic cusp (1974)

Previous calculations of β = 1 cusp losses are extended to the case where there exists a third ‘adiabatic’ invariant of the particle motion, related to the magnetic moment, and additional to the particle energy and angular momentum. Simple analytic results are obtained for the particle and energy loss rate from a Maxwellian plasma in both plane and axisymmetric geometry, electric fields being assumed zero everywhere. The results are valid for a plasma radius large relative to the ion gyro-radius, in which case the adiabaticity in the sense used reduces the loss rate by a factor ⅔λ⅔ to give an overall scaling as λ–⅔ with external mirror ratio λ. The absolute value is about a factor two less than the previously accepted result (for λ = 1 only) for an axisymmetric cusp. cusp. The enhanced scaling with A arises from the absence of a certain class of particles in the sheath, which must be everywhere adiabatic; its applicability to a simple theta pinch is queried, however. The end loss rate of angular momentum is also obtained, and is non-zero at a point cusp. This is shown to lead to rapid rotational instability in a collisionless theta pinch.
Chaotic-OOK UWB MODEM Using New Unipolar ZCD Codes for Wireless PAN (2006)

In this paper, we propose a chaotic-OOK (on-off keying) UWB (ultra wideband) modem using new unipolar ZCD (zero correlation duration) spreading code having interference cancellation property for IEEE 802.15.4a WPAN (wireless personal area network).
Pressure Transients in Hydraulic Pipelines (1969)

Equations of motion for a cylindrical tube containing a fluid are developed from a consideration of the forces and moments in the tube wall. These equations are solved for boundary conditions representing the situation where the fluid is flowing steadily through a horizontal pipe and a valve at the downstream end is closed instantaneously. The solution gives theoretical results for the usual water-hammer wave but also predicts the existence of a precursor wave. Expressions are derived for the velocities of propagation of both transients and their associated pressure changes. A comprehensive series of experiments has been carried out. Some interesting and probably unique results were obtained, which demonstrate the behavior of both transients. Measurements of velocity and pressure change have been made. The effect of axial restraint on the pipe is demonstrated.
A modified Kleinert Controlled Mobilization Splint following flexor tendon repair. (1984)

The Controlled Mobilization Splint as described by Kleinert for use following flexor tendon repair has been modified to more closely simulate the normal range of motion of the fingers and in particular to increase the range of motion at the distal interphalangeal joint and so enhance the relative gliding of the flexor digitorum superficialis and flexor digitorum profundus tendons and hence possibly to reduce potential intertendinous adhesions.

Cytotoxic Constituents of the Stems of <i>Cinnamomum </i><i>subavenium</i> (2006)

The aim of this study was to evaluate the cytotoxic effects of three new butanolides, subamolides A - C (1-3), and a new secobutanolide, secosubamolide (4), on the human colorectal cancer cell line SW480. Compounds 1-4 are new and were isolated from the stems of Cinnamomum subavenium, along with 17 known compounds. The structures of 1-4 were determined by spectroscopic analysis. Propidium iodide staining and flow cytometry were used to evaluate DNA damage of the treated SW480 cells, and it was found that 1-4 caused DNA damage in a dose-dependent manner after 24 h of treatment.
The bordered triangular matrix and minimum essential sets of a digraph (1974)

A partitioning strategy of sparse matrices is dealt with. In particular, the problem of transforming a nonsingular matrix by symmetric permutation to an optimal bordered triangular form (BTF) is solved. It is shown that the problem is equivalent to the determination of a minimum essential set of a directed graph. An efficient algorithm is given for finding minimum essential sets of a digraph. The method depends on, as a preliminary step, graph simplication using local information at a vertex. A circuit-generation technique based on vertex elimination is then introduced. The algorithm is illustrated with a complete example. A simple electrical network is used to illustrate the use of the BTF in the sparse tableau approach of network analysis.
Servo Control of Magnetic Gears (2011)

This paper considers the analysis and application of magnetic gearbox and magnetic coupling technologies and issues surrounding their use in high performance servo control systems. An analysis of a prototype magnetic coupling is used as a basis for demonstrating the underlying nonlinear torque transfer characteristics, nonlinear damping, and “pole-slipping” features when subjected to overtorque (overload) conditions. It is also shown how pole-slipping results in a consequential loss of control. A theoretical investigation into the suppression of mechanical torsional resonances in transmission systems encompassing these highly compliant magnetically coupled components is included along with experimental results from a demonstrator drive train. Automatic detection of pole slipping and a reconfigurable controller are also investigated. By addressing these issues, the proposed techniques extend the application scope of magnetic gear/coupling technologies to more demanding applications than those hitherto considered possible-specifically, for use in servo control systems and high-bandwidth mechanical drive trains.

The review intends to present and recapitulate the current knowledge on the roles and importance of regulatory RNAs, such as microRNAs and small interfering RNAs, RNA binding proteins and enzymes processing RNAs or activated by RNAs, in cells infected by RNA viruses. The review focuses on how non-coding RNAs are involved in RNA virus replication, pathogenesis and host response, especially in retroviruses HIV, with examples of the mechanisms of action, transcriptional regulation, and promotion of increased stability of their targets or their degradation.
Atom location in complex lattices: Pb in α-Al<sub>2</sub>O<sub>3</sub> (1980)

Abstract The channeling technique has been used to locate Pb implanted into α-Al2O3 single crystal. The main purpose has been to learn how to obtain information about the location of an impurity in a complex structure. A Pb location is proposed according to data of full angular scans through different axial and planar channeling dips.
Air jet noise exposure rapidly increases blood pressure in young borderline hypertensive rats (1991)

The present study tested the hypothesis that air jet noise exposure elicits sympathetically-mediated increases in the blood pressure of weaning-aged borderline hypertensive rats (BHR). BHR were the F1 offspring of spontaneously hypertensive female rats and male Wistar-Kyoto rats. Beginning at weaning (4 weeks of age), restrained BHR were exposed to air jet noise (30-120 s pulses of 120 dB) for 2 h/day, 5 days per week. Controls were restrained but did not receive air jet noise exposure. After only 1 week of air jet exposure, the systolic blood pressure (SBP) levels of the noise-exposed rats were increased significantly above those of restrained controls. Measures of mean arterial pressure (MAP) made in the home cage after 2 weeks of noise exposure confirmed the increased SBP. Ten weeks of air jet noise exposure increased MAP compared with restrained controls (144 +/- 4 versus 128 +/- 4 mmHg), with both SBP and diastolic blood pressure (DBP) being significantly increased. Baroreceptor sensitivity, assessed by bradycardic responses to graded doses of phenylephrine (0.5, 1, 2 and 4 micrograms/kg, intravenously), did not differ from restrained controls after 10 weeks of noise exposure. Autonomic (largely sympathetic) influence on home-cage blood pressure, inferred from ganglion blockade with chlorisondamine, also did not differ between groups after 10 weeks of stress. After maximal vasodilation with hydralazine, the DBP of air jet noise-exposed rats was somewhat higher than restrained controls (62 +/- 5 versus 49 +/- 3 mmHg; P = 0.08), suggesting that structural changes may have contributed to the increased MAP in air jet noise-exposed rats.(ABSTRACT TRUNCATED AT 250 WORDS)
Using Executive Assertions for Testing. (1979)

Abstract : One of the ways of assuring greater reliability of software is to improve testing techniques. Three of the key problems associated with software testing are: choosing adequate test cases, assuring correctness of the results, and reducing, the high cost of testing. Some degree of automation is required to help solve these problems. By combining the automated capability of adaptive testing with the use of executable assertions, it is possible to execute a program with a large number of test cases over a wide range of input values. The usual goal of adaptive testing is to maximize some performance value (objective function) for the software by automated perturbation of the input parameters. This technique only indirectly leads to locating errors, because of the time-consuming tasks of examining the usual output from the program. In software testing, the primary goal is to locate the maximum number of errors rather than maximize the performance value. Since software errors can be detected by executable assertions, these assertions can be used to define an objective function for the Adaptive Tester so that a program can be tested automatically and a mapping made of its 'error space.' A search algorithm is used to generate new test cases based on past performance data about the number of assertion violations. Software testing can become much more efficient and effective through the use of adaptive testing with assertions, because such extensive testing increases the possibility of finding any existing errors and of improving software reliability.

Muscle stiffness, strength loss, swelling and soreness following exercise‐induced injury in humans. (1993)

1. In order to study injury-related changes in muscle stiffness, injury to the elbow flexors of thirteen human subjects was induced by a regimen of eccentric exercise. 2. Passive stiffness over an intermediate range of elbow angles was measured with a device which held the relaxed arm of the subject in the horizontal plane and stepped it through the range of elbow angles from 90 deg to near full extension at 180 deg. The relation between static torque and elbow angle was quite linear over the first 50 deg and was taken as stiffness. 3. Stiffness over this range of angles more than doubled immediately after exercise and remained elevated for about 4 days, and may result from low level myofibrillar activation induced by muscle stretch. 4. Arm swelling was biphasic; arm circumference increased by about 3% immediately after exercise, fell back toward normal, then increased by as much as 9% and remained elevated for as long as 9 days. 5. Ultrasound imaging showed most of the swelling immediately following the exercise to be localized to the flexor muscle compartment; subsequent swelling involved other tissue compartments as well. 6. Muscle strength declined by almost 40% after the exercise and recovery was only slight 10 days later; the half-time of recovery appeared to be as long as 5-6 weeks.
Cryogenic Temperature Measurement Using Rayleigh Backscattering Spectra Shift by OFDR (2014)

We present a method to realize temperature variation measurement in the cryogenic environment (e.g., at 76 K) using Rayleigh backscattering spectra (RBS) shift in standard single mode optical fiber by optical frequency-domain reflectometry. By analyzing the relationship of effective sensing segment size of fiber (or sensing spatial resolution), minimal measurable temperature variation, and temperature response of RBS shift, we found minimal measurable temperature variation in the cryogenic environment can be improved by increasing effective sensing segment size. Our experiments show that at a relatively high temperature (e.g., above 195 K), minimal measurable temperature variation is 0.21 K with an effective sensing segment size of 8 cm. When the temperature is very low (e.g., at 76 K), minimal measurable temperature variation can still maintain 0.34 K by simply increasing the effective sensing segment size of fiber to 48 cm.
GEOMETRIC MODELS FOR THE ORIENTATION OF HIGH RESOLUTION OPTICAL SATELLITE SENSORS (2005)

Images taken by high resolution optical satellite sensors are available with different product levels, starting with the original images over close to original images, improved by the sensor calibration, to projections to a plane with constant object height and orthoimages based on very course digital elevation models (DEMs). All imaging satellites are equipped with satellite positioning systems like GPS and attitude control systems. Some very high resolution optical satellite systems do have precise attitude determination systems allowing a geo-reference sufficient for some purposes. The direct sensor orientation is available as satellite position together with attitudes or as rational polynomial coefficients (RPCs) describing the relation between object and image position by the relation of polynomials. An improvement of the orientation based on control points is necessary. The number and type of required unknowns is not the same for the different sensors. Images projected to a plane with constant height or a course DEM do require a different mathematical model for the correct georeferencing. For some of these image products no information about the sensor geometry is published, so a geometric reconstruction or a simplified mathematical model has to be used. In addition for some images additional parameters are required for reaching the highest possible accuracy. The geometric models for handling original images are well known, but some have to be improved by special adapted parameters for an optimal solution. Not in any case orientation parameters are available with acceptable accuracy, so in some cases nearly the whole orientation is not known. An overview about different solutions with advantages and disadvantages together with the achievable accuracy will be given.
Spatial disorientation in general aviation accidents (1978)

Spatial disorientation (SD) was the third highest "cause" of fatal accidents in small, fixed-wing aircraft and closely related to the second highest "cause"--"continued VFR flight into adverse weather." SD was a cause or factor in 16% of all fatal accidents. When SD was ascribed as a cause or factor in an accident, 90% of the time that accident involved fatalities. Small, fixed-wing aircraft under 12,500 lb (570 kg) accounted for 97.3% of all SD accidents. Inclement weather was associated with 42% of all fatal accidents, and SD was a cause or factor in 35.6% of these. Flight was initiated into and continued into adverse weather in 19.7 and 68.7%, respectively, of SD weather-related fatal accidents. Fog (56.8%) and rain (41.8%) were the most prevalent adverse weather conditions. These and other data attest to the importance of this psychophysiological phenomenon in flight safety.

Ivacaftor for patients with cystic fibrosis (2014)

Ivacaftor is an oral bioavailable potentiator of the cystic fibrosis transmembrane conductance regulator protein. It is the first therapeutic agent that has been registered for clinical use which targets the basic defect in people with cystic fibrosis who carry a G551D mutation or other rarer specific gating mutations. Clinical trials have shown consistent and impressive clinical benefit that appears to be sustained over time in people with cystic fibrosis who carry a G551D mutation and similar benefits have been seen in those who carry rarer gating mutations. Ivacaftor is orally administered twice daily with a dose that does not vary between children aged 6 years through to adult life in patients with G551D. It appears to be well tolerated although there are potential interactions with drugs that are metabolised through CYPP450 CYP3A. Ivacaftor is also currently being trialled in combination with correctors for patients with the most common mutation of cystic fibrosis transmembrane conductance regulator the F508del mutation.
Solution analysis for SIP security threats (2009)

Session Initial Protocol (SIP) is widely used for handling multimedia signaling. Because SIP is widely used in many multimedia applications, it becomes an attractive target to attackers. Actually, in contrast to traditional telephone networks, SIP works at the application layer in IP networks. It is thus faced to not only the IP-networks security issues, but also to new issues which are related to the SIP protocol directly. In this paper, we present the most relevant SIP-related security vulnerabilities and threats; then, we discuss the different security mechanisms that can be deployed to overcome the SIP security issues while putting emphasis the most important ones. Afterwards, taking into account the targeted security property, we propose adaptable solutions to the SIP threats already identified and we present our implementation and simulation test bed to experiment two versions of the SIP Asterisk software. Finally, we draw out conclusions and we introduce some perspectives to improve the security of multimedia applications.
