Transducers and repetitions

by Maxime Crochemore, Communicated M. Nivat - Theoretical Computer Science , 1986
"... Abstract. The factor transducer of a word associates to each of its factors (or subwc~rds) their first occurrence. Optimal bounds on the size of minimal factor transducers together with an algorithm for building them are given. Analogue results and a simple algorithm are given for the case of subseq ..."

On donne des bornes optimales sur la taille du transducteur minimal d'un mot ainsi qu'un algorithme

Repetitive paroxysmal tachycardia originating in the left atrium

by G. Von Bernuth, G. G. Belz , 1973
"... Three patients with repetitive supraventricular paroxysmal tachycardia are described, one of them with an atrial septal defect in addition. All three patients were asymptomatic; two, however, had a striking cardiomegaly (one of these is the patient with atrial septal defect). The electrocardiogram s ..."

Two-gigahertz repetition-rate, diode-pumped, mode-locked Nd:YLF laser

by K. J. Weingarten, D. C. Shannon, R. W. Wallace, U. Keller , 1990
"... A diode-pumped Nd:YLF laser has been acousto-optically mode locked at a 2-GHz repetition rate, giving pulse widths of 7 psec with an average power of 135 mW at a wavelength of 1.047,m. The 2-GHz pulse rate corresponds to a free-space cavity length of 7.5 cm, while the laser's actual cavity leng ..."

Purification and characterization of the Fas-ligand that induces apoptosis

by Takashi Suda, Shigekazu Nagata , 1994
"... Fas is a 45-kD cell surface protein belonging to the tumor necrosis factor/nerve growth factor receptor family, and transduces the signal for apoptosis. The cytotoxic T lymphocyte (CTL) hybridoma, PC60-dl0S requires the presence of Fas on target cells to induce cytolysis in target ceils. This CTL ce ..."

Thermomechancial Characterization in a Radiant Energy Imager Using Null Switching

by Javaneh Boroumand , Imen Rezadad , Ammar Alhasan , Evan Smith , Robert E Peale
"... Abstract Thermomechanical noise for a MEMs-based infrared detector using null switching (US patent 7977635) depends on vibrational amplitude, since IR radiation is transduced to a change in the duty cycle of a repetitively closing switch. Equipartition theorem determines the maximum rms vibrational ..."

Factors That Contribute to Wrist- Hand-Finger Discomfort in Diagnostic Medical Sonographers and Vascular Technologists

by unknown authors
"... A cross-sectional representative sample of 1722 sonographers and vascular technologists was analyzed using quantitative/qualitative methods to reveal that 60 % are experiencing wrist-hand-finger discomfort, believed to be from work-related repetitive injury. The years of scanning accumulated by the ..."

and Solutions

by Sonographers
"... Due to remarkable advances in technology, sonographers today are working more efficiently, serving considerably more patients per day. One would assume this to be a benefit, when in fact a new problem has surfaced directly related to these achievements. Ultrasound exams require a peculiar type of mu ..."

of muscular effort on the part of the sonographer. Tiny muscle tears that are the result of repetitive manipulations of the transducer, without adequate rest between exams, progress to more extensive muscular damage. The muscular damage can lead to career-ending injury. The purpose of this article

Dynamic buckling of actin within filopodia

by Natascha Leijnse, Lene B Oddershede, Poul M Bendix
"... Filopodia are active tubular structuresprotruding from the cell surface which allow the cell to sense and interact with the surrounding environment through repetitive elongation-retraction cycles. The mechanical behavior of filo-podia has been studied by measuring the traction forces exerted on exte ..."

Research Papers Acoustic Estimation of Resonance Frequency and Sonodestruction

by Of Sonovue Microbubbles, Rytis Jurkonis, Nerijus Lamanauskas , 2014
"... Acoustic properties of ultrasound (US) contrast agent microbubbles (MB) highly influence sonopo-ration efficiency and intracellular drug and gene delivery. In this study we propose an acoustic method to monitor passive and excited MBs in a real time. MB monitoring system consisted of two separate tr ..."

The first transducer delivered over an interval of 1 s US pulses (1 MHz, 1 % duty cycle, 100 Hz repetition frequency) with stepwise increased peak negative pressure (PNP), while the second one continuously monitored acoustic response of SonoVue MBs. Pulse echo signals were processed according
