Direct electron detection for EBSD of low symmetry & beam sensitive ceramics.

Electron backscatter diffraction (EBSD) is a powerful tool for determining the orientations of near-surface grains in engineering materials. However, many ceramics present challenges for routine EBSD data collection and indexing due to small grain sizes, high crack densities, beam and charge sensitivities, low crystal symmetries, and pseudo-symmetric pattern variants. Micro-cracked monoclinic hafnia, tetragonal hafnon, and hafnia/hafnon composites exhibit all such features, and are used in the present work to show the efficacy of a novel workflow based on a direct detecting EBSD sensor and a state-of-the-art pattern indexing approach.

Improving the radiological prediction of surgical resection of nonfunctioning pituitary adenomas.

Purpose: Nonfunctioning pituitary adenomas (NFPAs) are benign tumors growing in the sellar region. Total surgical excision of the lesion is recommended as the preferred treatment choice with preservation of adjacent structures. The objective is to establish a radiological score to predict the feasibility of NFPA total surgical excision.

Improved access and care through the implementation of virtual Hallway, a consultation platform in Nova Scotia: preliminary findings from a feasibility evaluation.

Background: While previous studies have examined various platforms that enable providers to connect, Virtual Hallway (VH) stands out with its unique features. The value add is that this online platform connects primary care providers and specialists for synchronous phone-based conversations and aims to reduce referrals and enhance the quality of referrals. VH allows providers to easily log in, select the required specialty, book call times, receive reminders, and have calls documented, ensuring a high connection rate.

Extraventricular Neurocytoma of the Sellar Region Presenting With Syndrome of Inappropriate Antidiuresis.

Neurocytomas are neuronal tumors that are usually intraventricular. Rare cases can arise from extraventricular sites. To our knowledge, only 29 cases of extraventricular neurocytoma of the sellar region (EVNSR) have been reported in the literature.
