Factors Associated with Mothers' Knowledge about Sudden Infant Death Syndrome
O Mundo da Saúde, 2023 Sudden Infant Death Syndrome is defined as the death of any infant under one year of age, with a sleeping position, in the prone position, being the most important risk factor.

Entanglement Sudden Death and Sudden Birth in Semiconductor Microcavities [PDF]
, 2011 We explore the dynamics of the entanglement in a semiconductor cavity QED containing a quantum well. We show the presence of sudden birth and sudden death for some particular sets of the system parameters.

Sudden Death of Entanglement: Classical Noise Effects [PDF]
Opt. Commun. 264, 393 (2006), 2006 When a composite quantum state interacts with its surroundings, both quantum coherence of individual particles and quantum entanglement will decay. We have shown that under vacuum noise, i.e., during spontaneous emission, two-qubit entanglement may terminate abruptly in a finite time [T. Yu and J. H.

Journal of Veterinary Internal Medicine, 2022 Background There are no reports on the number of fatalities or causes of death in the Norwegian and Swedish harness racehorses. Objectives The incidence rates (IRs), risk factors, and postmortem findings in horses that died or were euthanized associated ...

Sudden death and sudden birth of entanglement in common structured reservoirs [PDF]
, 2008 We study the exact entanglement dynamics of two qubits in a common structured reservoir. We demonstrate that, for certain classes of entangled states, entanglement sudden death occurs, while for certain initially factorized states, entanglement sudden birth takes place.

The Geometry of Entanglement Sudden Death [PDF]
New Journal of Physics 9 (2007) 237, 2007 In open quantum systems, entanglement can vanish faster than coherence. This phenomenon is usually called sudden death of entanglement. In this paper sudden death of entanglement is discussed from a geometrical point of view, in the context of two qubits.

Brugada Syndrome and GPD1L: Definite Genotype-Phenotype Association?
CardiogeneticsThe GPD1L gene encodes a small cytoplasmic protein that is involved in the regulation of sodium currents. Alterations in this gene have been associated with Brugada syndrome.

Entanglement Sudden Death in Band Gaps [PDF]
, 2009 Using the pseudomode method, we evaluate exactly time-dependent entanglement for two independent qubits, each coupled to a non-Markovian structured environment. Our results suggest a possible way to control entanglement sudden death by modifying the qubit-pseudomode detuning and the spectrum of the reservoirs.

Quantum error correction may delay, but also cause, entanglement sudden death [PDF]
Phys. Rev. A 77, 052307 (2008), 2008 Dissipation may cause two initially entangled qubits to evolve into a separable state in a finite time. This behavior is called entanglement sudden death (ESD). We study to what extent quantum error correction can combat ESD. We find that in some cases quantum error correction can delay entanglement sudden death but in other cases quantum error ...

Sudden death of distillability in qutrit-qutrit systems [PDF]
Phys.Rev.A 80, 012331 (2009), 2009 We introduce the concept of distillability sudden death, i.e., free entangled states can evolve into non-distillable (bound entangled or separable) states in finite time under local noise. We describe the phenomenon through a specific model of local dephasing noise and compare the behavior of states in terms of the Bures fidelity. Then we propose a few
