Symbiotic expressions
(2011)We introduce symbiotic expressions, a method for algebraic simplification within a compiler, in lieu of an SMT solver, such as Yices or the Omega Calculator. Symbiotic expressions are compiler-generated expressions, ... -
Symmetric and asymmetric dimethylarginine inhibit arginine transport and nitric oxide synthesis in J774 macrophages
(Portland Press Proceedings, 1996) -
Symmetries of Automata
(2015-03-24)For a given reachable automaton A, we prove that the (state-)endomorphism monoid End(A) divides its characteristic monoid M(A). Hence so does its (state-)automorphism group Aut(A), and, for finite A, Aut(A) is a homomorphic ... -
THE SYMMETRY OF BILATERAL ASHI-WAZA THROWS EXECUTION IN YOUTH U-14 CATEGORY JUDOKAS
(Faculty of Kinesiology, University of Zagreb, Croatia, 2023-06-20)Objective. In judo, highly skilled judokas pose a higher bilateral quality of arm and leg movements. This study aimed to examine the quality of bilateral throw execution of the selected Ashi-Waza (leg throwing) techniques ... -
Symmetry structure in discrete models of biochemical systems : natural subsystems and the weak control hierarchy in a new model of computation driven by interactions
(2015-07-28)Interaction Computing (IC) is inspired by the observation that cell metabolic/regulatory systems construct order dynamically, through constrained interactions between their components and based on a wide range of possible ... -
Symposium introduction - ethics and sustainable agri-food governance: appraisal and new directions
(2019-06-01)This Symposium contributes to a theoretical and methodological discussion on the role of ethics and responsibility in the governance of agri-food systems, as drivers for transitions towards sustainability. The papers in ... -
Symposium on ‘Nutrition and health in children and adolescents’ Session 4: Obesity prevention in children and adolescents The effect of physical activity on body fatness in children and adolescents
(2006)With the increasing prevalence of childhood obesity, there is an urgent need to identify risk factors that are amenable to preventative action. However, there is a remarkable lack of consistency between studies that have ... -
Symptom clusters in chronic kidney disease and their association with people’s ability to perform usual activities
(2022-03-02)Background: People living with a long-term condition, such as chronic kidney disease (CKD), often suffer from multiple symptoms simultaneously, making symptom management challenging. This study aimed to identify symptom ... -
Symptomless infection by Rhynchosporium commune in relation to control of barley leaf blotch
(2011)Rhynchosporium leaf blotch (caused by Rhynchosporium commune) is the most economically important disease of barley in the UK, but epidemics can be difficult to control with fungicides and the basis of cultivar resistance ... -
Symptomless infection of Rhynchosporium secalis on leaves of winter barley
(1990-06-30)Areas of leaf blotch lesions were assessed visually on green leaves sampled from a barley crop in March and April. When these leaves were examined further, firstly on a light table and then microscopically after clearing ... -
Synaptic depression enables neuronal gain control
(2009)To act as computational devices, neurons must perform mathematical operations as they transform synaptic and modulatory input into output firing rate. Experiments and theory indicate that neuronal firing typically represents ... -
Synaptic plasticity and pattern recognition in cerebellar Purkinje cells
(Springer Nature, 2014)Many theories of cerebellar learning assume that long-term depression (LTD) of synapses between parallel fibres (PFs) and Purkinje cells is the basis for pattern recognition in the cerebellum. Here we describe a series of ... -
A Synchronisation Facility for a Stream Processing Coordination Language
(2015-08-24)In this thesis we present the AstraKahn project that aims to provide environment for stream processing applications with an automatic resource and concurrency management based on communication demand. At the moment the ... -
Synchronization of inertial memristive neural networks with time-varying delays via static or dynamic event-triggered control
(2020-09-03)This paper investigates the synchronization problem of inertial memristive neural networks (IMNNs) with time-varying delays via event-triggered control (ETC) scheme and state feedback controller for the first time. First, ... -
Synchronization Through Uncorrelated Noise in Excitatory-Inhibitory Networks
(2022-02-04)Gamma rhythms play a major role in many different processes in the brain, such as attention, working memory, and sensory processing. While typically considered detrimental, counterintuitively noise can sometimes have ... -
Synchronizing DDoS Defense at Network Edge with P4, SDN, and Blockchain
(2022-10-24)Botnet-originated DDoS attacks continue to plague the internet and disrupt services for legitimate users. While various proposals have been presented in the last two decades, the botnet still has advantages over the ... -
The synchronous relationship between somatic symptoms and psychological distress in early rheumatoid arthritis : findings from a prospective observational study.
(2012-05)The longitudinal relationship between somatic symptoms and psychological distress in rheumatoid arthritis (RA) is often assumed to be strong and bidirectional. However, despite previous research identifying strong ... -
Synchrony : A spiking-based mechanism for processing sensory stimuli
(2012)Synchronous behaviour of neurons is both beneficial and detrimental to the neural code. On the one extreme, synchronous firing activity is well known to be a symptom of epileptic seizures, whilst on the other synchrony ...
