Analysis of Excitability in Resonant Tunneling Diode-Photodetectors.

We investigate the dynamic behaviour of resonant tunneling diode-photodetectors (RTD-PDs) in which the excitability can be activated by either electrical noise or optical signals. In both cases, we find the characteristics of the stochastic spiking behavior are not only dependent on the biasing positions but also controlled by the intensity of the input perturbations. Additionally, we explore the ability of RTD-PDs to perform optical signal transmission and neuromorphic spike generation simultaneously.

Etiologic Workup in Cases of Cryptogenic Stroke: A Systematic Review of International Clinical Practice Guidelines.

Background and Purpose- Identifying the etiology of acute ischemic stroke is essential for effective secondary prevention. However, in at least one third of ischemic strokes, existing investigative protocols fail to determine the underlying cause. Establishing etiology is complicated by variation in clinical practice, often reflecting preferences of treating clinicians and variable availability of investigative techniques.

Etiologic workup in cases of cryptogenic stroke: protocol for a systematic review and comparison of international clinical practice guidelines.

Background: Stroke is a leading cause of death and disability worldwide. Identifying the aetiology of ischaemic stroke is essential in order to initiate appropriate and timely secondary prevention measures to reduce the risk of recurrence. For the majority of ischaemic strokes, the aetiology can be readily identified, but in at least 30% of cases, the exact aetiology cannot be determined using existing investigative protocols.

Optical direct intensity modulation of a 79GHz resonant tunneling diode-photodetector oscillator.

We report on the direct intensity modulation characteristics of a high-speed resonant tunneling diode-photodetector (RTD-PD) with an oscillation frequency of 79 GHz. This work demonstrates both electrical and optical modulation and shows that RTD-PD oscillators can be utilized as versatile optoelectronic/radio interfaces. This is the first demonstration of optical modulation of an RF carrier using integrated RTD-PD oscillators at microwave frequencies.

A novel and simple technique to allow detection of the position of the R-waves from intraventricular pressure waveforms: application to the conductance catheter method.

A simple and novel technique that utilizes the zero-crossing points of the first time derivative of intra-ventricular pressure (dP/dt) to mark systole, is proposed. Discrete differentiation of the sampled pressure waveform is calculated using a difference equation. Filtration of high-frequency noise in dP/dt is achieved using a low-pass Butterworth filter of order 4 and a cutoff frequency of 10 Hz.

Validation of the conductance catheter method for measurement of ventricular volumes under varying conditions relevant to cardiac surgery.

The development of the conductance catheter method has enabled continuous measurement of intraventricular volume in vivo, thus making assessment of pump performance of the heart in vivo possible using pressure-volume analysis. However, this method has not been validated under conditions where pump rate, conductance, viscosity, and temperature of the fluid in the heart chamber is changed as happens in cardiac surgery. To validate the method, pressure-volume data were measured by conductance catheter in a physical model of the human left ventricle.

1. We have previously shown that brief voluntary isometric contractions of upper arm flexor muscles performed for one respiratory cycle elicit a significant decrease in the R-R interval. The present study was designed to determine if similar changes are produced by non-voluntary electrically evoked contractions and, if so, to establish the consistency and repeatability of the associated changes in the R-R interval.

[A case of post-traumatic intrapericardial hernia in a child].

Rupture of the diaphragm and pericardium after blunt abdominal injury is a rare and serious lesion. This rupture can produce a secondary subacute or chronic cardiac tamponade due to herniation of the abdominal contents into the pericardial cavity. Diagnosis is difficult and therefore rarely mode early.

[Leakproof external urinary derivation. Apropos of a new technic].

Confronted by the need to find a system for cutaneous urinary derivation free of leakage, the authors used an invaginated isolated ileal loop which serves as a form of system of continence. When the bladder is intact the bladder neck is closed and the intestinal cuff attached directly to the bladder. This results in a leakproof trans-intestinal cystostomy.
