A negative inotropic effect of acetylcholine in the presence of several phosphodiesterase inhibitors.
1981
The phosphodiesterase inhibitors papaverine, theophylline and 3-isobutyl-1-methylxanthine (IBMX) reveal a negative inotropic effect of acetylcholine in cat ventricular heart muscle. This effect in unrelated to beta-adrenoceptor stimulation and possibly mediated by the accumulation of cyclic GMP.

Lietotne papildus sniedz iespēju apkopot komerciālo un labdarības izstāžu komerciālos panākumus. Mākslas galeriju darbinieki lietotnei var pievienot galerijas telpas un to…
Polynomial and horizontally polynomial functions on Lie groups
2022
We generalize both the notion of polynomial functions on Lie groups and the notion of horizontally affine maps on Carnot groups. We fix a subset $S$ of the algebra $\mathfrak g$ of left-invariant vector fields on a Lie group $\mathbb G$ and we assume that $S$ Lie generates $\mathfrak g$. We say that a function $f:\mathbb G\to \mathbb R$ (or more generally a distribution on $\mathbb G$) is $S$-polynomial if for all $X\in S$ there exists $k\in \mathbb N$ such that the iterated derivative $X^k f$ is zero in the sense of distributions. First, we show that all $S$-polynomial functions (as well as distributions) are represented by analytic functions and, if the exponent $k$ in the previous defini…
Smart Assistance for Students and People Living in a Campus
2019
Being part of one of the fastest growing area in Artificial Intelligence (AI), virtual assistants are nowadays part of everyone's life being integrated in almost every smart device. Alexa, Siri, Google Assistant, and Cortana are just few examples of the most famous ones. Beyond these off-the-shelf solutions, different technologies which allow to create custom assistants are available. IBM Watson, for instance, is one of the most widely-adopted question-answering framework both because of its simplicity and accessibility through public APIs. In this work, we present a virtual assistant that exploits the Watson technology to support students and staff of a smart campus at the University of Pa…
Cognitive Computing supported Medical Decision Support System for Patient’s Driving Assessment
2018
To smartly utilize a huge and constantly growing volume of data, improve productivity and increase competitiveness in various fields of life; human requires decision making support systems that efficiently process and analyze the data, and, as a result, significantly speed up the process. Similarly to all other areas of human life, healthcare domain also is lacking Artificial Intelligence (AI) based solution. A number of supervised and unsupervised Machine Learning and Data Mining techniques exist to help us to deal with structured data. However, in a real life, we pretty much deal with unstructured data that hides useful knowledge and valuable information inside human-readable plain texts,…
Pico: A data acquisition program for picosecond laser spectroscopy
1992
Abstract A data acquisition and control program for picosecond pump and probe experiments has been developed. The program PICO is written in C-programming language for maximum efficiency. The software which runs on an IBM PC compatible microcomputer controls a stepper motor driven optical delay, and at the same time collects data from a digital lock-in amplifier. PICO can be used to control any experiment utilizing two-beam pump probe technique. The modular structure of the software allows for easy implementation with different hardware configurations. The program includes: measurement option, manual control of the delay line using a joystick and functions for file retrieval and editing. Ad…

X-Ray Nanotomography of Individual Pulp Fibre Bonds Reveals the Effect of Wall Thickness on Contact Area
2019
Fibre bonds play an essential role in various properties of paper. Much research has focused on their strength, but the determination of the actual contact area also provides a challenge. Many of the research methods rely on optical tools, which are restricted by the wavelength of light that is utilised. Novel X-ray computed tomography devices utilise X-rays in studying the inner structure of materials, and surpass the optical methods in terms of resolution, allowing detection of even smaller details and variations in distance between the fibres in the bond intersection area. X-ray nanotomography was used to image 26 individual cellulose fibre bonds made of springwood and summerwood fibres …
Les macrophytes pour estimer l'état écologique des cours d'eau : l'Indice Biologique Macrophytique en Rivière et la Directive Cadre sur l'Eau
2005
Les macrophytes sont explicitement désignés par la Directive européenne et les textes français de son application comme éléments biologiques à considérer pour évaluer l`état écologique des cours d`eau dans le cadre de la DCE. A l`issu de tests comparatifs d`indices pré-existants et de différents travaux et tests nationaux, le premier protocole formalisé (indices GIS, Haury et al., 1996) a évolué vers l`Indice Biologique Macrophytique en Rivière (IBMR), normalisé par l`AFNOR en 2003. Quelles réponses ce protocole d`évaluation de l`état écologique des cours d`eau peut-il apporter aux besoins liés à l`application de la DCE en France, et comment complète-t-il les outils développés actuellement …
Enhancing news recommendation using a personalized content manager
2018
The surge in the amount of information available on the internet and the number of users utilizing such information poses new challenges for information systems. This rapid growth in information is palpable in the news provisioning domain where users spend time deciding which of the many channels provides news in a most reliable and useful fashion. In the last few years, News aggregation platforms are now present which reduces the time users spends in consuming news from multiple sources. But news provisioning is more than just aggregating and presenting news. It must also include taking into cognizance users’ needs. Therefore, recommendation algorithms are developed by information systems …
