Reducing Processing Delay in Dataflow-oriented Middleware Systems for Smart Camera Applications (2014)

Dataflow-oriented processing is an attractive paradigm for smart camera applications. In this paper we present a dataflow-oriented middleware system to support the development of such applications on resource-limited distributed systems. Our main contribution includes the reduction of the overall processing delay by delaying the data generation and by the just-in-time transfer of data elements. A side effect of this delayed data transfer is also a reduction of the memory requirement for the communication links. We introduce the basic algorithm and present experimental results of our middleware system running in a distributed environment.
Oxidative Cyclization of Linalol by Various Microorganisms (1985)

(±) Linalol is cyclized into cis and trans linalol oxides by various microorganisms. This reaction, assuming an intermediate epoxidation step, is analogous to the corresponding step proposed for the biosynthesis of ionophorous antibiotics.
Pressure dependence of the solubility of Ar and Kr in melts of the system SiO<sub>2</sub>-NaAlSi<sub>2</sub>O<sub>6</sub> (2000)

The solubilities of Ar and Kr in supercooled melts in the system SiO2-NaAlSi2O6 have been studied at temperatures of 1200 °C (SiO2), 1000 and 750 °C (NaAlSi3O8), and 800 °C (NaAlSi2O6) at pressures from 200 to 6000 bar. Gas sorption experiments were performed in an internally heated pressure vessel, and noble gas concentrations in quenched samples were analyzed by absolute analytical techniques [gas chromatography (GC), and thermogravimetry (TG), gravimetry]. Comparison of the results from this study with other absolute techniques (Rutherford-backscattering, mass spectrometry) is possible for silica and exhibit excellent agreement. This agreement leads us to conclude that our silica glasses with an Ar concentration of 1.02 wt% and a Kr concentration of 0.54 wt% are suitable as standard materials. Solubility increases linearly with increasing pressure for all three compositions. In SiO2 the solubility of Ar and Kr increases with pressure with nearly parallel slopes, whereas Ar and Kr exhibit diverging slopes in NaAlSi3O8 and NaAlSi2O6. The linear relationship between fugacity and dissolved gas below 2-3 kbar, indicates that Henry’s law constants (in units of 106 bar) for Ar in SiO2, NaAlSi3O8, and NaAlSi2O6 are 0.94, 3.15, and 5.71, respectively, and for Kr are 1.38, 5.69, and 9.28, respectively. The experimental results can be modeled by two alternative thermodynamic approaches. First, assuming mixing of noble gases with the network of the melt, partial molar volumes (in cm3/mol) can be calculated in SiO2, NaAlSi3O8, and NaAlSi2O6 for Ar as 25.9 ± 1.3, 21.1 ± 1.6, and 21.1 ± 0.7, respectively and for Kr as 24.3 ± 1.8, 27.6 ± 0.8, and 24.7 ± 0.9, respectively. Second, assuming the volume change upon solution to be zero, a Langmuir- Isotherm can be applied yielding saturation levels M (in units of 1020 sites/cm3 melt) in SiO2, NaAlSi3O8, and NaAlSi2O6 for Ar as 3.82 ± 0.6, 1.33 ± 0.2, and 0.72 ± 0.08, respectively and for Kr as 3.49 ± 0.7, 0.56 ± 0.05, and 0.42 ± 0.06, respectively. Highest solubility is observed in all three melts for Ar. Solubility decreases with increasing substitution of Si4+ by Na+ + Al3+. The dependence of solubility on composition supports the structural model for melts along the join SiO2-NaAlSi2O6 based on a stuffed tridymite-like structure.
Error analysis in acoustic elastography. I. Displacement estimation (1997)

Correlation between acoustic echo signals obtained before and after application of an external compressional force provides information about the internal deformation of an elastic medium. In this paper, the variance for displacement estimated from an echo data segment and the covariance between two windowed segments that may overlap are derived. The signal and noise spectra are Gaussian and independent. The dependence of the displacement variance on input signal-to-noise ratio (SNRi), time-bandwidth product W, fractional bandwidth Y-1, and the rate of displacement variation with depth a is investigated. The relationship between a and the other experimental parameters is crucial for understanding how signal decorrelation affects displacement error. The expression for displacement variance reduces to the Cramer-Rao lower bound result when a = 0 and W > > 1 for both bandpass and base-band signals. When a not equal to 0 displacement variance increases, and there is an optimal window length at W = square root of 20/a square root of 1 + Y2 for which the displacement variance is minimum. Narrow-band signals produce larger errors than broadband signals for long observation windows when a not equal to 0 and just the opposite when a = 0. Errors are greatest for displacements estimated from the envelope of narrow-band signals. Finally, a general expression for the minimum displacement variance for arbitrary signal and noise spectra is derived as a function of the experimental parameters. These results form a framework for analyzing strain estimates in elastography, the subject of a companion paper.
A Railway Track Geometry Measuring Trolley System Based on Aided INS (2018)

Accurate measurement of the railway track geometry is a task of fundamental importance to ensure the track quality in both the construction phase and the regular maintenance stage. Conventional track geometry measuring trolleys (TGMTs) in combination with classical geodetic surveying apparatus such as total stations alone cannot meet the requirements of measurement accuracy and surveying efficiency at the same time. Accurate and fast track geometry surveying applications call for an innovative surveying method that can measure all or most of the track geometric parameters in short time without interrupting the railway traffic. We provide a novel solution to this problem by integrating an inertial navigation system (INS) with a geodetic surveying apparatus, and design a modular TGMT system based on aided INS, which can be configured according to different surveying tasks including precise adjustment of slab track, providing tamping measurements, measuring track deformation and irregularities, and determination of the track axis. TGMT based on aided INS can operate in mobile surveying mode to significantly improve the surveying efficiency. Key points in the design of the TGMT’s architecture and the data processing concept and workflow are introduced in details, which should benefit subsequent research and provide a reference for the implementation of this kind of TGMT. The surveying performance of proposed TGMT with different configurations is assessed in the track geometry surveying experiments and actual projects.
Actin and Microtubules in Cell Motility: Which One is in Control? (2004)

The cytoskeleton is composed of three distinct elements: actin microfilaments, microtubules and intermediate filaments. The actin cytoskeleton is thought to provide protrusive and contractile forces, and microtubules to form a polarized network allowing organelle and protein movement throughout the cell. Intermediate filaments are generally considered the most rigid component, responsible for the maintenance of the overall cell shape. Cytoskeletal elements must be coordinately regulated for the cell to fulfill complex cellular functions, as diverse as cell migration, cell adhesion and cell division. Coordination between cytoskeletal elements is achieved by signaling pathways, involving common regulators such as the Rho guanosine-5'-triphosphatases (GTPases). Furthermore, evidence is now accumulating that cytoskeletal elements participate in regulating each other. As a consequence, although their functions seem well defined, they are in fact overlapping, with actin playing a role in membrane trafficking and microtubules being involved in the control of protrusive and contractile forces. This cytoskeletal crosstalk is both direct and mediated by signaling molecules. Cell motility is a well-studied example where the interplay between actin and microtubules appears bidirectional. This leads us to wonder which, if any, cytoskeletal element leads the way.
Coupling of Arylamines with Coordinated Arylazopyrimidines in Palladium(II) Complexes (2002)

2-(Arylazo)pyrimidine (1) reacts with palladium chloride and gives Pd(aapm)Cl2 (2) which undergoes a palladium(II)-mediated novel carbon−nitrogen bond formation reaction of the aromatic amines to the ortho-C−H function of the pendant aryl ring in the coordinated 2-(arylazo)pyrimidine. The reactant, Pd(papm)Cl2 (2a) and the product, Pd(papm-N-C6H4-OCH3-p)Cl (5a) have been characterised by X-ray crystal structure. The coupled products exhibit low energy transitions (NIR region) unlike the parent complex, Pd(aapm)Cl2. The cyclic voltammogram shows an oxidation couple at positive potential to SCE. The EHMO calculation suggests that the spectral feature in Pd(aapm)Cl2 (2) is due to the MLCT [d(Pd)⇄π*(azo)] whereas in Pd(aapm-N-C6H4-X-p)Cl (3−6) the transition at the NIR region is due to the intravalence charge transfer (IVCT) transition.
High-performance N-polar GaN enhancement-mode device technology (2013)

In this paper, we report the recent progress in the high-frequency performance of enhancement-mode devices in the novel N-polar GaN technology and provide a pathway for further scaling. The intrinsic advantages of electron confinement, polarization doping of the back-barrier and the absence of a source barrier in N-polar GaN technology were leveraged with polarization engineering with a top barrier for enhancement mode operation and advanced self-aligned source/drain technology for low parasitic access resistances. The scalability of the device structures are explored in terms of short-channel effects and high-frequency performance. Low-field electron mobility in vertically scaled channel was also investigated providing insights on the scattering mechanism. © 2013 IOP Publishing Ltd.
Presynaptic cholinergic action in the hippocampus (1989)

The hippocampus is among the regions in the brain richest in M1 cholinergic receptors. Topical application of acetylcholine (ACh) onto hippocampal slices produces a characteristic complex response consisting of a depolarization, an increase in input resistance especially upon depolarization and a blockade of a slow afterhyperpolarization (AHP). The first two of these responses can be recorded also in non-cholinergic septal neurons in an area which contains about 8% of the M1 muscarinic receptors found in the hippocampus. The responses of hippocampal but not septal neurons to ACh involve an increase in the spontaneous synaptic activity and a decrease in evoked responses to afferent stimulation. The dissociated hippocampal culture was used to study these presynaptic effects. The neurons in culture possess muscarinic receptors which develop gradually over a period of several weeks after plating. ACh rarely depolarizes hippocampal neurons in culture. Instead, it causes an increase in spontaneous discharge of small postsynaptic currents (PSC's) and a marked decrease of large, evoked PSC's. In some cultured hippocampal cells ACh reduced ICa without affecting any of several outward K currents studied. It is suggested that ACh reduces evoked activity by reducing Ca currents at presynaptic terminals.

Spatio-temporal composition in multimedia applications (2002)

The motivation for this research work is the lack of a complete declarative method for representative spatio-temporal composition of objects in the current multimedia document standards and authoring tools. We define such a model which is based on a set of spatial and temporal relationships between actors in multimedia applications. Our work exploits existing approaches for spatial and temporal relationships. We extend these relationships in order to cover the specific requirements of multimedia applications and we integrate the results in a uniform framework for spatio-temporal composition representation.
CODEINE AND MORPHINE IN<i>PAPAVER SOMNIFERUM</i>GROWN IN A CONTROLLED ENVIRONMENT (1976)

Alkaloids in the terminal capsule of M–89 variety of P. somniferum rise and plateau as the plant matures in a controlled environment. Lancing immature capsules does not increase yield of codeine plus morphine in the above-ground plant, but lancing may translocate alkaloids upward to the capsule. Poppies produced a high proportion of codeine relative to morphine. This effect is probably due to some environmental condition imposed.
Characterizing the soft error vulnerability of multicores running multithreaded applications (2010)

Multicores have become the platform of choice across all market segments. Cost-effective protection against soft errors is important in these environments, due to the need to move to lower technology generations and the exploding number of transistors on a chip. While multicores offer the flexibility of varying the number of application threads and the number of cores on which they run, the reliability impact of choosing one configuration over another is unclear. Our study reveals that the reliability costs vary dramatically between configurations and being unaware could lead to a sub-optimal choice.

[Lethality of the dnaB thermosensitive mutation of E. coli : comparison with thymine-less death]. (1975)

In a dnaB thermosensitive mutant of the bacterium E. coli, a shift to non-permissive conditions leads to the immediate cessation of DNA synthesis and results in a sizable loss of viability. Under conditions where protein synthesis is inhibited, either by addition of antibiotics (chloramphenicol, rifampicin) or by amino-acids starvation, there is a marked increase in viability. This is reminiscent of the behavior of thymine-deprived bacteria and suggests that both types of death, induced by a block in the displacement of the DNA-replicative fork, follow the same pattern.
Alternatives to IVF: the outcome of 1071 first GIFT procedures (1989)

Gamete intra-Fallopian transfer (GIFT) is the most important treatment method for infertile couples that has been developed since in-vitro fertilization and embryo transfer (IVF/ET) became available. Analysis of the data of 1071 first GIFT procedures is presented and the predominant factors affecting success are discussed. An overall pregnancy rate of 33.6% was achieved in this group of patients who were unselected in relation to age, number of oocytes transferred, quality of sperm and response to ovulation induction. The success of GIFT is dependent upon the number and quality of oocytes transferred and upon the quality of the sperm. Pregnancy occurred in 21.4% of patients receiving up to four oocytes compared with 40.3% in whom five or more were transferred. Multiple pregnancy rates however were 17.3% in the first group and 32.3% in the second group. Age is a major factor influencing the chances of success with patients less than 30 years of age achieving a 40.2% pregnancy rate reducing to 19.2% in the over 40 group. Conversely the spontaneous abortion rate increased from 23.4% in the under 30 group to 48.6% in those over 40 years of age. No pregnancies were achieved when sperm motility was less than 20% in the original specimen, whereas pregnancy rates of up to 20% resulted when sperm density was below 10 million. The overall results of this study show comparable success rates for different causes of infertility and that there is a definite association between the outcome of treatment and the number and quality of gametes transferred. A philosophy of flexibility in the treatment of infertile couples is advocated.
Gene Therapy Clinical Trials in the Human Brain (2009)

A properly designed and executed clinical trial that addresses an import question and delivers a definitive result can change the practice of medicine worldwide. This book encompasses a bench-to-bedside approach and serves as an excellent guidance for translating preclinical studies to early phase I/II and phase III trials. In the first part, the book covers preclinical science with respect to animal models of various neurological diseases, FDA requirements for preclinical studies, translation of animal to patient studies and scaling up from animal to human studies. In the second part, the design of phase I/II trials and the use of biomarkers as surrogate endpoints are discussed. With regard to phase III trials, FDA and European requirements, specific design issues, relevant clinical endpoints as well as data management and quality are examined. Topics specific to multicenter trials, such as design, recruitment of special populations, monitoring, ethical and consent issues are also covered. Finally, genetics, gene therapy, imaging and surgical devices are reviewed.This publication is highly recommended to clinician researchers, such as neurologists, neurosurgeons, pediatric neurologists and neonatologists, who want to design and conduct clinical trials in the neuroscience, but also to nurses, research coordinators and clinical pharmacologists.
ANFIS : Adap tive-Ne twork-Based Fuzzy Inference System (1993)

The architecture and learning procedure underlying ANF'IS (adaptive-network-based fuzzy inference system) is pre- sented, which is a fuzzy inference system implemented in the framework of adaptive networks. By using a hybrid learning procedure, the proposed ANFIS can construct an input-output mapping based on both human knowledge (in the form of fuzzy if-then rules) and stipulated input-output data pairs. In the sim- ulation, the ANFIS architecture is employed to model nonlinear functions, identify nonlinear components on-linely in a control system, and predict a chaotic time series, all yielding remarkable results. Comparisons with artificial neural networks and earlier work on fuzzy modeling are listed and discussed. Other extensions of the proposed ANFIS and promising applications to automatic control and signal processing are also suggested.
Temperature Dependence of the Pyroelectric Effect in Cadmium Sulfide (1965)

This paper describes the observed temperature dependence of the pyroelectric effect in a hexagonal cadmium sulfide crystal between 78 and 345\ifmmode^\circ\else\textdegree\fi{}K. The methods used to obtain the response and evaluate the results are described. The error is evaluated at each of the ambient temperatures. The measurements were made along the crystal's axis of symmetry. Most of the polarization appears to be due to the dipole expansion of interatomic bonds which are principally covalent.
Small Brush DC Motors using Soft Magnetic Composites for 42V Automotive Applications (2003)

<div class="htmlview paragraph">This paper presents new design approaches for the realization of small DC motors with SMC, for 42V automotive applications. Several structural solutions are proposed which use new kinds of windings to improve the performance and to minimize the production cost. These structures are using a multi-layer concentrated winding with a small number of slots. They are well adapted to the production process of metal powder parts. The new design is validated by the experimental performance of a SMC 42V Brush-DC prototype and by a comparative analysis with a classical 12V laminated motor used for an automotive 180W application. A 50% gain on the copper volume is obtained for the same specifications and performance of this application.</div>
The European Community Respiratory Health Survey (1994)

The European Community Respiratory Health Survey (ECRHS) was planned to answer specific questions about the distribution of asthma and health care given for asthma in the European Community. Specifically, the survey is designed to estimate variations in the prevalence of asthma, asthma-like symptoms and airway responsiveness; to estimate variations in exposures to known or suspected risk factors for asthma, and assess to what extent these variations explain the variations in the prevalence of disease; and to estimate differences in the use of medication for asthma. The protocol provides specific instructions on the sampling strategy adopted by the survey teams, as well as providing instructions on the use of questionnaires, the tests for allergy, lung function measurements, tests of airway responsiveness, and blood and urine collection. The principal data collection sheets and questionnaires are provided in the appendices, together with information on coding and quality control. The protocol is published as a reference for those who wish to know more of the methods used in the study, and also to give other groups who wish to collect comparable data access to the detailed methodology.
An iPhone application for upper arm posture and movement measurements (2017)

There is a need for objective methods for upper arm elevation measurements for accurate and convenient risk assessments. The aims of this study were (i) to compare a newly developed iOS application (iOS) for measuring upper arm elevation and angular velocity with a reference optical tracking system (OTS), and (ii) to compare the accuracy of the iOS incorporating a gyroscope and an accelerometer with using only an accelerometer, which is standard for inclinometry. The iOS-OTS limits of agreement for static postures (9 subjects) were -4.6° and 4.8°. All root mean square differences in arm swings and two simulated work tasks were <6.0°, and all mean correlation coefficients were >0.98. The mean absolute iOS-OTS difference of median angular velocity was <13.1°/s, which was significantly lower than only using an accelerometer (<43.5°/s). The accuracy of this iOS application compares well to that of today's research methods and it can be useful for practical upper arm measurements.
Light‐Emitting Electrochemical Cells with Crown Ether as Solid Electrolyte (1997)

Light‐emitting electrochemical cells (LECs) are reported with lithium salt/crown ether complex as the solid electrolyte. By careful choice of the combination of electroluminescent polymer, crown ether, and lithium salt, LECs are demonstrated with good quantum efficiency, fast response, and long stress life. The results demonstrate the importance of phase compatibility to LEC performance.
A busman's holiday (1976)

Some consider that the British Association for the Advancement of Science is as much an anachronism as that reminder of its past importance, the BA screw. However, such pessimism was not in evidence at the 138th annual meeting, when the 2000 or so participants clearly found their week at the University of Lancaster last September a worthwhile experience.
A sub-0.5 μA/MB data-retention DRAM (2002)

This sub-0.5 /spl mu/A/MB data retention DRAM with relaxed junction biased (RTB), plate-floating leakage monitoring (PFM) and VBB biased pull down word line driver (PDPWD) extends retention time (T/sub RT/) about 3-times and reduces refresh current (I/sub RF/) to /spl les/0.4 /spl mu/A/MB. In addition, a gate-received VBB detector (GRD) and dynamically-controlled reference generators (DCRG) reduce dc retention current (I/sub DC/) to /spl les/0.1 /spl mu/A/MB. This DRAM allows a 20 MB RAM disk to retain data for 2.5 years with a single button-shaped 190 mAh lithium battery and can be substituted for SRAM.
