Derivation of Conditions for the Normal Gain Behavior of Conical Horns

open access: yesInternational Journal of Antennas and Propagation, 2007
Monotonically increasing gain-versus-frequency pattern is in general expected to be a characteristic of aperture antennas that include the smooth-wall conical horn.

An Effective Oral Drug Delivery Route for Pharmacokinetic Complications: Spirulina Lipid Nanotechnology System

open access: yesAdvanced Science, EarlyView.
Spirulina‐nano system facilitates the formation of drug coating on spirulina's surface through electrostatic adsorption. It targets intestinal villi effectively and overcomes the pharmacokinetic complications of IBS‐D. This system successfully carried out the treatment of multiple symptoms, including diarrhea, visceral hypersensitivity, mental symptoms,

Possible tendency of polled cattle towards larger ears

open access: yesRevista Colombiana de Ciencias Pecuarias, 2014
Background: the anatomy and physiology of bovid horns are consistent with their thermoregulatory function. Objective: to evaluate a possible correlation between ear and horn size, as key factors for body thermoregulation.

Legal assessment of ingrown horns and other horn-related anomalies in cattle and sheep

open access: yesAnimal Welfare
Cattle and sheep horns have the potential to grow in such a way that the horn bends toward the animal’s head and, if left untreated, may penetrate the skin, causing pressure, pain, and suffering.

Partial Reprogramming in Senescent Schwann Cells Enhances Peripheral Nerve Regeneration via Restoration of Stress Granule Homeostasis

open access: yesAdvanced Science, EarlyView.
In this study, it is discovered that pathological accumulation of Runx2+ Schwann cell clusters​ during axonal regeneration is a key factor impairing nerve repair in aging. This pathology is associated with ​dysregulation of stress granule homeostasis.

A Game of Horns: Transnational Flows of Rhino Horn

open access: yes, 2015
A multi-sectorial regime of protection including international treaties, conservation and security measures, demand reduction campaigns and quasi-military interventions has been established to protect rhinos. Despite these efforts, the poaching of rhinos and trafficking of rhino horn continue unabated.

A Multifunctional Molecular Probe for Multimodal Imaging‐Guided Potent Photothermal/Photodynamic Therapy of Endometriosis

open access: yesAdvanced Science, EarlyView.
The cRGD‐ILD molecular probe integrates clinically available components: a cRGD peptide (integrin αvβ3 targeting), ICG (for fluorescence/photoacoustic imaging and phototherapy), and Gd‐DTPA (MRI contrast). Utilizing small size and receptor targeting, it achieves selective lesion accumulation.
