Investigation of the equivalent circuit parameters and design of a dual polarised dual frequency aperture coupled microstrip antenna [PDF]

, 2013
This paper presents a simplified approach to the design of a single feed dual polarised, dual frequency (1.9 and 2.4 GHz) aperture coupled microstrip antenna. Using simulation and practical investigation, the coupling between the microstrip feed line and

A workflow for 3D printing highly accurate, customized human skull models for anatomical education and clinical practice

Anatomical Sciences Education, EarlyView.
Our custom workflow creates anatomically accurate and diverse 3D skull models. Precise sex‐specific anatomical detail is ensured by CT‐based segmentation. Our models capture anatomical variations and pathologies. Our cost‐effective 3D printing workflow enhances model durability and fidelity.

Anterior cingulate cortex neuron subtypes differentially regulate seizures

Epilepsia, EarlyView.
Abstract Objective This study aimed to investigate the regulatory roles of distinct neuronal subtypes within the anterior cingulate cortex (ACC) in acute seizures and to identify cell type‐specific mechanisms underlying seizure modulation in this region. Methods Acute seizure models were established in mice via pentylenetetrazol injection.

Pneumocoele sinus: Computed tomographic findings and surgical approach in a 2‐year‐old Cob filly

Equine Veterinary Journal, EarlyView.
Abstract Background Pneumosinus dilatans and pneumocoele sinus describe abnormal hyperpneumatisation of paranasal sinuses, with the latter being accompanied by thinning of bony walls. Although recognised in human and equine medicine, to the authors' knowledge, this condition's computed tomography (CT) findings and successful surgical approach in horses

Morphological Stabilization of CsPbBr3 Quantum Dot Films Enabled by PVC‐g‐PMMA Graft Copolymer Encapsulation for Water‐Robust Color Conversion

Small, EarlyView.
Poly(vinyl chloride)‐graft‐poly(methyl methacrylate) encapsulation enabled formation of water‐stable CsPbBr3‐quantum‐dot fims with enhanced photoluminescence (PL) retention upon exposure to water, UV radiation, and ethanol. Time‐dependent ex situ transmission electron microscopy with quantitative particle segmentation identified the coefficient of ...

Prelacrimal Transmaxillary‐Orbital Approach for Resection of Lateral Extraconal Orbital Cavernous Hemangioma

World Journal of Otorhinolaryngology - Head and Neck Surgery, EarlyView.
ABSTRACT Endoscopic orbital surgery is likely a reasonable option for patients with orbital cavernous hemangiomas (OCH) medial to the optic nerve (ON). The endoscopic resection of OCH lateral to the ON is extremely challenging. Zhou et al. first described the endoscopic prelacrimal recess approach (PLRA) for the management of the maxillary sinus and ...
