Stigmergic gene transfer and emergence of universal coding
(2009)We consider a simple information-theoretic model for evolutionary dynamics approaching the “coding threshold,” where the capacity to symbolically represent nucleic acid sequences emerges in response to a change in environmental ... -
Still a Spam-a-Lot nation?
(2007-04-13)Considers recent case law in relation to unsolicited marketing emailing. -
Still and Still Moving : Solo show, video installation
(2010-01-06)The Process Room, Irish Museum of Modern Art, Dublin SASM is a site-specific video project made under the research concerns of 'Fixity and Motion' and part of a series of installations created with projected video into ... -
Still Desperate After All These Years : The Post-Feminist Mystique and Desperate Housewives
(I. B. Tauris, 2006) -
Still sad after successful renal transplantation : are we failing to recognise depression? An audit of depression screening in renal graft recipients
(2010)Background: Depression is common in chronic physical illness, including renal graft recipients. There is evidence that depression is an independent marker of poorer prognosis in dialysis patients. In the UK, screening is ... -
Stillbirth and loss : family practices and display
(2013-02)This paper explores how parents respond to their memories of their stillborn child over the years following their loss. When people die after living for several years or more, their family and friends have the residual ... -
Stimulant and hallucinogenic novel psychoactive substances; an update
(2023-11-22)Introduction The renewed interest in considering a range of stimulants, psychedelics and dissociatives as therapeutics emphasizes the need to draft an updated overview of these drugs’ clinical and pharmacological issues. ... -
Stimulated pepsinogen secretion from dispersed abomasal glands exposed to Ostertagia species secretion
(1990)Carbachol and secretions from Ostertagia species parasites significantly (P less than 0.001) stimulated isolated preparations of dispersed gastric glands from bovine and ovine abomasal mucosa to secrete pepsinogen. Atropine ... -
Stimuli‐Responsive Polymers for Engineered Emulsions
(2024-02-23)Emulsions are complex. Dispersing two immiscible phases, thus expanding an interface, requires effort to achieve and the resultant dispersion is thermodynamically unstable, driving the system toward coalescence. Furthermore, ... -
A Stochastic based Physical Layer Security in Cognitive Radio Networks: Cognitive Relay to Fusion Center
(Institute of Electrical and Electronics Engineers (IEEE), 2020-01-16)Cognitive radio networks (CRNs) are found to be, without difficulty wide-open to external malicious threats. Secure communication is an important prerequisite for forthcoming fifth-generation (5G) systems, and CRs are not ... -
Stochastic dynamics and high capacity associative memories
(Institute of Electrical and Electronics Engineers (IEEE), 2002) -
A Stochastic Method to Physical Layer Security of an Amplify-and-Forward Spectrum Sensing in Cognitive Radio Networks: Secondary User to Relay
(Institute of Electrical and Electronics Engineers (IEEE), 2019-07-22)In this paper, a framework for capitalizing on the potential benefits of physical layer security in an amplify-and-forward cooperative spectrum sensing (AF-CSS) in a cognitive radio network (CRN) using a stochastic geometry ... -
Stochastic model of template-directed elongation processes in biology
(2010)We present a novel modular, stochastic model for biological template-based linear chain elongation processes. In this model, elongation complexes (ECs; DNA polymerase, RNA polymerase, or ribosomes associated with nascent ... -
Stochastic protein folding simulation in the three-dimensional HP-model
(2008)We present results from three-dimensional protein folding simulations in the HP-model on ten benchmark problems. The simulations are executed by a simulated annealing-based algorithm with a time-dependent cooling schedule. ... -
Stochastic resonance phenomena in spin chains
(2009)We discuss stochastic resonance-like effects in the context of coupled quantum spin systems. We focus here on an information-theoretic approach and analyze the steady state quantum correlations (entanglement) as well as ... -
Stochastic signatures of involuntary head micro-movements can be used to classify females of ABIDE into different subtypes of neurodevelopmental disorders.
(2017-06-07)Background: The approximate 5:1 male to female ratio in clinical detection of Autism Spectrum Disorder (ASD) prevents research from characterizing the female phenotype. Current open access repositories [such as those in ...
