Decay of the free-theory vacuum of scalar field theory in de Sitter spacetime in the interaction picture

open access: yes, 2008
A free-theory vacuum state of an interacting field theory, e.g. quantum gravity, is unstable at tree level in general due to spontaneous emission of Fock-space particles in any spacetime with no global timelike Killing vectors, such as de Sitter ...

Compound Heterozygous MRPS14 Variants Associated With Leigh Syndrome

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT MRPS14 (uS14m) is a nuclear‐encoded ribosomal protein important for mitochondria‐specific translation. To date, only a single individual with a recessive MRPS14‐related disorder (also known as COXPD38) has been reported. We report an additional subject possessing novel compound heterozygous MRPS14 variants (p.Asp37Asn, p.Asn60Asp). The subject

Effect of intravenous albumin on renal impairment and mortality in patients with cirrhosis and spontaneous bacterial peritonitis.

open access: yesNew England Journal of Medicine, 1999
BACKGROUND In patients with cirrhosis and spontaneous bacterial peritonitis, renal function frequently becomes impaired. This impairment is probably related to a reduction in effective arterial blood volume and is associated with a high mortality rate ...

spontaneity

open access: yesпроект байкал
The lifespan of architectural objects varies in the widest range – from a few days to millennia. Most often a built object begins to change, to transform even before the construction is finished, and continues to do so every day of its existence. The elements and the passage of time change its appearance, but people bring even greater changes, painting

EEG Response to Sedation Interruption Complements Behavioral Assessment After Severe Brain Injury

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Accurate assessment of the level of consciousness and potential to recover in patients with severe brain injury underpins crucial decisions in the intensive care unit but remains a major challenge for the clinical team. The neurological wake‐up test is a widely used assessment tool. However, many patients' behavioral responses during

Softer than normal, but not as soft as one might think: Spontaneous flux lattices in ferromagnetic spin-triplet superconductors

open access: yes, 2004
A theory is developed for the spontaneous vortex lattice that is expected to occur in the ferromagnetic superconductors ZrZn_2, UGe_2, and URhGe, where the superconductivity is likely of spin-triplet nature.

Spontaneous neurotransmitter release and Ca2+—How spontaneous is spontaneous neurotransmitter release?

open access: yesCell Calcium, 2008
Neurotransmitter release from neurons takes place at specialized structures called synapses. Action potential-evoked exocytosis requires Ca(2+) influx through voltage-gated Ca(2+) channels. Spontaneous vesicle fusion occurs both in the absence of action potentials and without any apparent stimulus and is hence thought to be Ca(2+)-independent. However,

Pregnancy Outcomes of Targeted Synthetic Disease‐Modifying Antirheumatic Drugs Among Patients With Autoimmune Diseases: A Scoping Review

open access: yesArthritis Care &Research, EarlyView.
Objective Targeted synthetic disease‐modifying antirheumatic drugs (tsDMARDs) have expanded the management of autoimmune diseases, including rheumatic diseases. As the use of these drugs grows, it is important to understand their effects on pregnancy.
