Do all giraffes have horns?

open access: yes, 2022
Giraffes don't have horns they have ossicones. Official records do not classify giraffes as trophy animals because they lack true keratin horns. Both males and females have fixed ossicones of fully developed bones that are growing from the frontal plate ...

Liquid‐Crystal‐Based Reconfigurable Intelligent Surface for 7 GHz Mobile Communication

open access: yesAdvanced Materials Technologies, EarlyView.
The glass‐based liquid‐crystal reconfigurable intelligent surface (LC‐RIS) integrates active‐matrix driving and blind‐greedy phase optimization within a 5G‐NR OFDM framework. This enables continuously tunable and autonomous enhancement of wireless coverage. Leveraging the transparency and manufacturability of liquid crystal panels, it is ideally suited

Wavelength‐Multiplexed 2D Beam Steering via a Passive Diffractive Network

open access: yesAdvanced Optical Materials, EarlyView.
Illustration of a wavelength‐multiplexed diffractive beam steering system, which is composed of K cascaded diffractive layers, each containing phase‐modulating elements that are jointly optimized using deep learning–based optimization. When illuminated with a set of wavelengths {λ1,λ2,…,λNw}$\{ {{{\lambda }_1},{{\lambda }_2},\ldots ,{{\lambda }_{{{N}_w}

HYPOBRANCHIAL APPARATUS IN CHICKEN AND GOOSE [PDF]

open access: yesAssiut Veterinary Medical Journal, 1994
The hypobranchial apparatus consists of unpaired median part and two branchial horns. The entoglossal bone is well developed in goose than in chicken. It is the longest bone (34.20 mm) in the latter one among the bones of the median part.

Photonic Time Crystals and Time‐Varying Electromagnetic Metamatter: A New Direction for Ultrafast Tunable Photonic and Microwave Materials and Devices

open access: yesAdvanced Science, EarlyView.
Photonic time crystals (PTCs) are systems in which electromagnetic parameters are modulated periodically in time, producing momentum bandgaps via temporal scattering rather than spatial Bragg processes. This review examines the theoretical frameworks, modeling, and computational tools for time‐varying media, and summarizes experimental demonstrations ...

VDAC1 Upregulation Induces Hyperexcitability of Nociceptive Sensory Neurons Via Enhanced Mitochondrial Atp Efflux in Neuropathic Pain

open access: yesAdvanced Science, EarlyView.
The mechanism diagram of VDAC1 mediating neuronal excitability and neuropathic pain. Briefly, VDAC1 is expressed in DRG neurons and is upregulated following CCI‐induced neuropathic pain. This upregulation enhances ATP transport from mitochondria to the cytoplasm in sensory neurons, leading to increased neuronal excitability and pain behavior.

The transfer of symbols and meanings: the case of the ‘horns of consecration’

open access: yesDocumenta Praehistorica, 2005
Sir Arthur Evans first used the term “horns of consecration” in 1901. Since then they have been interpreted in various ways as Moon idols (Mondidole), boat models, pot stands, loom stands, spit supports, and fire supports.
