Data and performance profiles applying an adaptive truncation criterion, within linesearch-based truncated Newton methods, in large scale nonconvex optimization.

In this paper, we report data and experiments related to the research article entitled "An adaptive truncation criterion, for linesearch-based truncated Newton methods in large scale nonconvex optimization" by Caliciotti et al. [1]. In particular, in Caliciotti et al.

Ram-pressure feeding of supermassive black holes.

When a supermassive black hole at the centre of a galaxy accretes matter, it gives rise to a highly energetic phenomenon: an active galactic nucleus. Numerous physical processes have been proposed to account for the funnelling of gas towards the galactic centre to feed the black hole. There are also several physical processes that can remove gas from a galaxy, one of which is ram-pressure stripping by the hot gas that fills the space between galaxies in galaxy clusters.

Hypoparathyroidism after total thyroidectomy: prospective evaluation and relation with early hypocalcemia.

Aim: Definitive hypoparathyrodism (hypo-PTH) represents one of the most dangerous complication after total thyroidectomy. Partial or total lesion or accidental removal of parathyroid glands is an unpredictable adverse event, although real incidence is not well defined, such as management of this deficit. We started a prospective evaluation of patients treated with total thyroidectomy in our centre, to identify incidence of hypo-PTH, symptomatic or not, in relation to incidence of early postoperative hypocalcemia in our experience.

Surgical approach to TIR3 cytology class A prospective evaluation.

Aim: Fine-needle aspiration (FNA) has proven to be a safe and reliable method of investigation of thyroid lesions. Referencing to European classification, the associated risk of malignancy for TIR3, category reserved for aspirates that contain architectural and/or nuclear atypia, is variable in such studies. Aims of study were evaluating safety of surgical approach, assessing perioperative parameters surgically related, and estimating neoplastic rate for TIR3 group.

Stochastic model of agent interaction with opinion leaders.

We analyze the problem of agents' interactions in a given population. The purpose of this paper is twofold. Starting from a scheme proposed by Galam [Physica A 320, 571 (2003)], which is based on a majority rule to treat the individuals' interactions, we first study some of its relevant properties.
