Cooperative Cognitive Relaying Under Primary and Secondary Quality of Service Satisfaction [PDF]
arXiv, 2014 This paper proposes a new cooperative protocol which involves cooperation between primary and secondary users. We consider a cognitive setting with one primary user and multiple secondary users. The time resource is partitioned into discrete time slots.

A Monte Carlo investigation of secondary electron emission from solid targets: spherical symmetry versus momentum conservation within the classical binary collision model [PDF]
, 2009 A Monte Carlo scheme is described where the secondary electron generation has been incorporated. The initial position of a secondary electron due to Fermi sea excitation is assumed to be where the inelastic collision took place, while the polar and azimuth angles of secondary electrons can be calculated in two different ways.

Predictors of Mortality in Patients With Multiple Endocrine Neoplasia Type 1
Clinical Endocrinology, EarlyView.SUMMARY Objective Multiple Endocrine Neoplasia Type 1 (MEN 1) is an autosomal dominant disease predisposing to hyperplasia and neoplasia in diverse endocrine tissues. Patients typically present with endocrine abnormalities before the age of 30 years and have reduced life expectancy.

Loop Homology of Bi-secondary Structures [PDF]
arXiv, 2019 In this paper we compute the loop homology of bi-secondary structures. Bi-secondary structures were introduced by Haslinger and Stadler and are pairs of RNA secondary structures, i.e. diagrams having non-crossing arcs in the upper half-plane. A bi-secondary structure is represented by drawing its respective secondary structures in the upper and lower ...

Global secondary CR invariants in dimension five [PDF]
arXiv, 2020 A global secondary CR invariant is defined as the integral of a pseudo-hermitian invariant which is independent of a choice of pseudo-Einstein contact form. We prove that any global secondary CR invariant on CR five-manifolds is a linear combination of the total $Q'$-curvature, the total $\mathcal{I}'$-curvature, and the integral of a local CR ...

Molecular mechanism for transcriptional regulation of the parathyroid hormone gene by Epiprofin
The FEBS Journal, EarlyView.The secretion of parathyroid hormone (PTH) from the chief cells in the parathyroid glands is regulated by the concentration of extracellular calcium. Epiprofin (Epfn) expression is induced by NFATc2 in response to elevated serum calcium, and Epfn negatively regulates PTH production.

International Journal of Endocrinology, 2009 Brown tumour represents a serious complication of hyperparathyroidism. Differential diagnosis, based on histological examination, is only presumptive and clinical, radiological and laboratory data are necessary for definitive diagnosis. Here we describe

Interference-Assisted Wireless Energy Harvesting in Cognitive Relay Network with Multiple Primary Transceivers [PDF]
arXiv, 2015 We consider a spectrum sharing scenario, where a secondary network coexists with a primary network of multiple transceivers. The secondary network consists of an energy-constrained decode-and-forward secondary relay which assists the communication between a secondary transmitter and a destination in the presence of the interference from multiple ...

X‐Linked Hypophosphataemia and Burosumab: A Systemic Disease With a New Treatment
Journal of Paediatrics and Child Health, EarlyView.ABSTRACT X linked hypophosphataemia (XLH) is a systemic, chronic condition that significantly impairs quality of life. In XLH, a phosphate regulating endopeptidase homologue X‐linked (PHEX) gene mutation leads to excess fibroblast growth factor 23 (FGF23), causing hypophosphataemia and subsequent rickets, lower limb deformity, pain and other sequelae ...

Mandibular Osteitis Fibrosa Cystica as First Sign of Vitamin D Deficiency
Case Reports in Dentistry, 2018 Introduction. Brown tumors of hyperparathyroidism are locally destructive bone lesions. They are the late clinical consequence of the disease. They can occur in primary, secondary, and rarely tertiary forms.
