Power Summation in an Open Resonator with Aperture Coupling Elements
Advanced ElectromagneticsThe paper considers the powers summation of two sources in a hemispherical open resonator (OR). A scheme with a E- tee waveguide was used. The study was carried out in the four-millimeter wavelength range.

Annals of Neurology, EarlyView.Objective Parkinson's disease (PD) is increasingly conceptualized as a disorder of large‐scale brain networks, yet whether and how frequency‐specific functional connectivity reorganizes across stages remains poorly understood. In this study, we used high‐density electroencephalography (EEG) to characterize cortico‐cortical functional connectivity ...

The Anatomical Record, EarlyView.Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

The Anatomical Record, EarlyView.Abstract Neuroanatomical research has progressed considerably in several vertebrate lineages, yet studies of reptilian brain morphology remain markedly underdeveloped. Here we provide the first description of macroscopic brain anatomy and its ontogeny in the viperid Bothrops moojeni, based on a sample of seven individuals.

Clade‐wide morphological and functional variation of the sauropsid columella
The Anatomical Record, EarlyView.Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Scoping literature review: Comparing MRI tractography methods for optic radiation analysis
The Anatomical Record, EarlyView.Abstract Accurate tractography mapping of the optic radiations is essential to avoiding post‐operative visual field deficits in patients undergoing temporal lobe surgery. This literature review highlights the current landscape of MRI tractography methods that are used to delineate the optic radiations (ORs), with a particular focus on the anterior ...

Production of 3D printed biomodels of the canine brain for veterinary neuroanatomy teaching
Anatomical Sciences Education, EarlyView.Abstract Teaching neuroanatomy presents multiple challenges to both students and teachers, as it is a subject with highly dense content that commonly causes the development of aversion by students, a phenomenon referred to as “neurophobia,” which has been documented in human and veterinary medicine students.

Experimental Study of Piezoelectrically Actuated Hemispherical Resonator Gyro
, 2013 本實驗研究彈性半圓球殼振動陀螺儀之行為，利用壓電材料之機電轉換特性其驅動與感測方式，做為半圓球殼陀螺儀的致動器與感測器，以持振迴路激發半圓球殼陀螺儀以第一模態即(2,1)模態持續共振，當旋轉時此模態因受到科氏力作用的影響，會產生模態漂移現象，再以抑制振動迴路將模態拉回原位，量測抑制振動迴路之訊號振幅變化量與旋轉角速度的關係，實驗結果節點抑制振動之訊號電壓變化值與所施加之角速度關係呈直線性關係，本實驗則以謝發華博士所分析推導之壓電驅動半圓球殼振動陀螺儀進行實驗驗證。最後加上一積分電路 ...

Hemispherical Dielectric Resonator Antenna Based on Apollonian Gasket of Circles-A Fractal Approach
, 2014 A novel, compact hemispherical dielectric resonator antenna based on Apollonian Gasket of circles is proposed. The Apollonian Gasket is a fractal generated from triplets of circles, where each circle is a tangent to the other two. The dielectric material

Anatomical Sciences Education, EarlyView.Abstract The study of neuroanatomy is fundamental in many scientific fields. Despite this, it is a challenging subject for students. As technology evolves, it is being increasingly incorporated into educational methods, including the teaching of neuroanatomy. Three‐dimensional (3D) visualizations are well suited for displaying neuroanatomy.
