Characterization of the 12S globulin complex of <i>Brassica napus</i> (1991)

Cruciferin (12S globulin) is the major seed protein in Brassica napus (oil seed rape). It is synthesized during seed development and consists of six subunit pairs. Each of these pairs is synthesized as a precursor containing one alpha and one beta chain. At least three different precursors exist (P1-3), giving rise to four different mature subunits (cru1-4). Several cruciferin clones were isolated from a seed mRNA cDNA library. Comparison of the deduced amino acid sequences of these clones to amino acid sequences of purified cruciferin chains and peptides identified them as coding for cru2/3 and cru4 subunits. From the amino acid sequences deduced from two overlapping cDNA clones, the precursor of the cru4 subunit was shown to consist of 465 amino acid residues. Comparison of cruciferin and cruciferin-related sequences from B. napus and Arabidopsis thaliana, respectively, suggested that early during evolution the Brassicaceae family only possessed two types of 11-12S globulin genes, like the present-day Fabaceae.

Uncertainty of Positioning and Displacement Measurements in Quantum and Thermal Regimes (2007)

We analyze the performance of position-sensing devices and of distance- or displacement-measuring instruments, and we find that the ultimate uncertainty at the quantum limit of detected signal is given by the same expression in all cases, namely, a characteristic length L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> divided by radicNph, the square root of the number of photons detected in the time interval of the measurement. We derive the expression of the length L <sub xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">c</sub> for well-known position-sensing devices (the quadrant photodiode and the position-sensing detector) and for several measuring instruments (pulsed and sine-wave-modulated rangefinders, triangulation telemeter, laser interferometer, and the optical rule). We also extend the analysis of the uncertainty results to the thermal regime case of detection, i.e., when the detector dark current and preamplifier noises are dominant with respect to quantum noise.

Wavelet methods for estimation of acoustically relevant parameters of musical signals (1990)

Wavelet transforms are a class of analysis and resynthesis methods that have been found useful in a variety of domains [Wavelets, edited by J. M. Combes, A. Grossmann, and Ph. Tehamitchian (Springer-Verlag, IPTI, 1989)]. They provide a two-dimensional (time and scale) description of one-dimensional signals. In this paper, wavelet transforms are used as the basis for an algorithm that represents an audio signal as a sum of “spectral components” (contributions obtained by amplitude modulation and slow frequency modulation around a frequency). A central role in this construction is played by the phase of the (complex-valued) wavelet transform; the interpretation of this phase is particularly simple and intuitive if the analyzing wavelet is chosen as an analytic signal (progressive wavelet). The parameters determined by the algorithm allow an additive reconstruction of the signal, as well as a variety of nonlinear modifications. These possibilities will be illustrated by several audio examples.
Triangular laser resonators with astigmatic compensation (2000)

The magnitudes and locations of the beam waists in both the sagittal and the tangential planes have been found by means of the ABCD matrix method for a triangular resonator. Equilateral and isosceles resonators are discussed, and curves are given from which resonators with astigmatism-free beams can be designed. A frequency-doubled triangular Nd ring laser has been constructed after this design, and it is demonstrated that this laser emits a single longitudinal mode with a circular TEM(00) Gaussian beam.
Signaling in Muscle Contraction (2015)

Signaling pathways regulate contraction of striated (skeletal and cardiac) and smooth muscle. Although these are similar, there are striking differences in the pathways that can be attributed to the distinct functional roles of the different muscle types. Muscles contract in response to depolarization, activation of G-protein-coupled receptors and other stimuli. The actomyosin fibers responsible for contraction require an increase in the cytosolic levels of calcium, which signaling pathways induce by promoting influx from extracellular sources or release from intracellular stores. Rises in cytosolic calcium stimulate numerous downstream calcium-dependent signaling pathways, which can also regulate contraction. Alterations to the signaling pathways that initiate and sustain contraction and relaxation occur as a consequence of exercise and pathophysiological conditions.

Protected environment for cancer patients. Effect of a prophylactic antibiotic regimen on the microbial flora of patients undergoing cancer chemotherapy (1968)

Eleven patients undergoing cancer chemotherapy in isolator units were treated with an oral, nonabsorbable prophylactic regimen in an attempt to reduce the incidence of infections caused by the patient's own endogenous flora. Ninety-two percent of 98 strains of aerobic bacteria in the stool were completely suppressed, as well as 100% of the anaerobes and 54% of the fungi. Only 66% of the strains from throat cultures and 88% of the strains isolated from nose cultures were completely suppressed. The antibiotic regimen had to be continued during the entire study, although the patients remained in a sterile environment. The patients tolerated the antibiotics quite well, and severe toxicity was observed in only one patient after prolonged administration.
CARBOHYDRATE ACCUMULATION IN OSMOTICALLY STRESSED CYANOBACTERIA (BLUE‐GREEN ALGAE): INTERACTIONS OF TEMPERATURE AND SALINITY (1985)

S ummary The effects of temperature and salinity on the carbohydrate accumulation profiles of a range of unicellular cyanobacteria (blue‐green algae) have been studied. Four isolates of Synechocystis sp. which usually accumulated glucosyl‐glycerol produced a second carbohydrate, sucrose, when grown in a seawater‐based medium at high temperature (35°C). In contrast, three sucrose‐accumulating isolates of Synechococcus , grown over a range of temperatures and salinities, did not produce a second detectable low molecular weight carbohydrate in any experimental treatment. The interaction of temperature and salinity was further examined in Synechocystis PCC 6714. Sucrose production was found to be favoured by high temperature and low salinity. The rate and extent of sucrose accumulation differed in cells grown at 20 and 37 °C reaching an upper asymptote 12 h after upshock at 37 °C and 24 h after upshock at 20 °C followed by a decrease to an approximately constant level after 96 h. This is the first demonstration of the accumulation of sucrose as a second osmotically active carbohydrate in cyanobacteria.
Regulation of Cardiac Contraction (1972)

Primary emphasis in this review will be placed o n recent significant ad­ vances in the following four areas: Biochemical integration in the myocardial cell (page 47). Structure-function relations in the contractile units of muscle and heart (page 156) . Methods for the assessment of ventricular function (page 161). Factors which affect the performance of the mammalian heart (page 71) . Important topics largely omitted which have received comprehensive review elsewhere include Mommaerts' review of the energetics of muscular contraction (1), Young's analysis of the molecular basis of muscular con­ traction (2), the review by Katz on contractile proteins of the heart (3) , Korner's review of integrated neural control mechanisms (4) , Johnson & Lieberman's analysis of excita tion-contraction coupling and the structure of the sarcotubular system (5) , and Levy & Berne's review of cardiac neural control and the coronary circulation (6).
A Simple Reconfigurable Antenna (2005)

When a semiconductor is irradiated with light or electrons of sufficient energy, the irradiated part will become conducting. This well-known mechanism can be used to create antennas with conducting parts controlled by the irradiating source, and structures reconfigurable by changing the irradiation patterns.
The Identity Management Kalman Filter (IMKF) (2006)

Tracking posterior estimates for problems with data association uncertainty is one of the big open problems in the literature on filtering and tracking. This paper presents a new filter for the on-line tracking of many individual objects with data association ambiguities. It tightly integrates the continuous aspects of the problem (locating the objects) with the discrete aspects (the data association ambiguities). The key innovation is a probabilistic information matrix that efficiently encodes identity information by linking world entities with internal tracks of the filter, enabling it to maintain a full posterior over the system amid data association uncertainties. The filter scales quadratically in complexity, just like a conventional Kalman filter, avoiding the exponential explosion of the association space. We derive the algorithm formally and present large-scale simulation results.

Involvement of SenC in Assembly of Cytochrome <i>c</i> Oxidase in <i>Rhodobacter capsulatus</i> (2005)

SenC, a Sco1 homolog found in the purple photosynthetic bacteria, has been implicated in affecting photosynthesis and respiratory gene expression, as well as assembly of cytochrome c oxidase. In this study, we show that SenC from Rhodobacter capsulatus is involved in the assembly of a fully functional cbb(3)-type cytochrome c oxidase, as revealed by decreased cytochrome c oxidase activity in a senC mutant. We also show that a putative copper-binding site in SenC is required for activity and that a SenC deletion phenotype can be rescued by the addition of exogenous copper to the growth medium. In addition, we demonstrate that a SenC mutation has an indirect effect on gene expression caused by a reduction in cytochrome c oxidase activity. A model is proposed whereby a reduction in cytochrome c oxidase activity impedes the flow of electrons through the respiratory pathway, thereby affecting the oxidation/reduction state of the ubiquinone pool, leading to alterations of photosystem and respiratory gene expression.
Analysis of the Low-Frequency Noise Reduction in Si(100) Metal–Oxide–Semiconductor Field-Effect Transistors (2011)

The low-frequency noise was already a strong limiting factor for radio frequency/analog integrated circuits and was expected to become soon for the digital ones. However, a very significant and effective reduction of the 1/f noise level has been realized for both n- and p-channel metal–oxide–semiconductor field-effect transistors (MOSFETs) by the means of two new fabrication processes, opening new horizons for the very large scale integration (VLSI) technology. Indeed, a significant reduction of more than two decades of the noise level has been achieved by implementing a new salicide structure for the source and drain contacts. Moreover, on account of a new process flow involving a newly developed plasma process for the realization of the gate oxide, one of the noise source, the induced mobility fluctuations, located in the channel and generating the 1/f noise has been neutralized in the case of the p-MOSFETs. Furthermore, the implementation of an adapted salicide structure in addition to the plasma process will make the insulator charge fluctuations the sole noise source in these devices.
Recent structural investigations of metallic polymers (1994)

Recent structural studies of the undoped and iodine-doped polyacetylenes (prepared by the Tsukamoto and co-workers method), PF6−-doped polypyrrole and polyaniline emeraldine base and (hydrochloric acid and camphorsulfonic acid) salts are presented. Some key features of the polymer chain array and its evolution with the conditions of preparation are emphasized. Special attention has been devoted to characterization of the various sources of structural disorder in the relationship with high conductivity and related properties exhibited by these three families of polymers. Variation in the structural order in both crystalline and amorphous regions correlates directly with the electrical and optical properties of the metallic state.
Production of Various Carbon Nanoclusters by Impact Reaction Using Light-Gas Gun as Simulation of Asteroid Collisions in Space (2011)

An impact production of carbon nanoclusters is carried out in nitrogen gas using a two-stage light-gas gun. A small polycarbonate ball (or a stainless steel ball) is injected at about 6.5 km/s into a pressurized target chamber to collide with an aluminum target (or a hexane + aluminum target) in 1 atm of nitrogen gas. We can confirm the production of many types of carbon nanoclusters such as aluminum-encapsulated carbon nanoparticles, carbon nanotubes, and balloonlike nanocarbons. Therefore, it is expected that many types of carbon nanoclusters are produced by impact reactions of asteroids in space, when such reactions take place in a carbon-rich atmosphere. Particularly on Titan satellite, a large number of carbon clusters produced by impacts of asteroids are expected to be stored.

Propuesta de un entorno de seguridad para la gestión de políticas en redes IP (2003)

Los mecanismos que se han venido utilizando hasta ahora para gestionar redes, servicios y aplicaciones estan empezando a mostrar limitaciones importantes debido, sobre todo, al aumento que estan experimentando, tanto en tamano como en complejidad, los sistemas a gestionar. El origen del problema proviene tanto del creciente interes que estan mostrando los proveedores de servicios y los operadores de telecomunicaciones por ofrecer nuevas aplicaciones y nuevos servicios del estilo de redes privadas virtuales, servicios de videoconferencia, o soporte de movilidad en las comunicaciones, como por el hecho de que el equipamiento de red sea cada dia mas numeroso y heterogeno, lo que lo hace ser, sin duda, mas complejo de gestionar. En este contexto parece clara la necesidad de una nueva aproximacion a los sistemas de gestion, caracterizada por ser segura y automatizada, y por reflejar en la medida de lo posible el caracter distribuido de los sistemas actuales de comunicaciones que se desean gestionar. En el contexto que se acaba de expresar en los anteriores apartados se define esta tesis doctoral, que tiene como principal objetivo el aportar una solucion a las limitaciones que se acaban de comentar, mediante la propuesta de un entorno de seguridad capaz de gestionar politicas en redes IP. Para lograr este objetivo toma como punto de partida el uso de Ipsec y de criptografia de clave publica como mecanismos para la provision de servicios de seguridad. Por otra parte, se basa en la labor de estandarizacion que se esta llevando a cabo en el seno del IETF con el odjetivo de crear entornos de comunicaciones gestionados por politicas. Nuestra solucion concreta esta basada en dos elementos principales, a saber, un sistema de gestion de confianza y un entorno de gestion de politicas. El primero de ellos se basa en el diseno de una infraestructura de clave publica que hemos denominado UMU-PKIv6, y un sistema de tarjetas inte
Beneficial Circulatory Effect of L-Arginine (1994)

L-Arginine is an essential amino acid for infants and growing children. This amino acid is a substrate for at least five enzymes identified in mammals, including arginase, arginine-glycine transaminase, kyotorphine synthase, nitric oxide synthase (NOS) and arginine decarboxylase. L-Arginine exerts antihypertensive and antiproliferative effects on vascular smooth muscles. NOS and arginine decarboxylase appear to be important for the effect of L-arginine on the circulatory system, since each produces nitric oxide (NO), a potent vasodilator, and agmatine, an endogenous noncatecholamine ligand for central alpha-2 adrenoceptors, from L-arginine. Several issues must be clarified before the mechanisms by which L-arginine exerts its effects on the circulatory system can be fully understood.
