A Neural Network Model of Auditory Scene Anaysis and Source Segregation [PDF]

open access: yes, 1994
In environments with multiple sound sources, the auditory system is capable of teasing apart the impinging jumbled signal into different mental objects, or streams, as in its ability to solve the cocktail party problem. A neural network model of auditory

NUMERICAL SIMULATION OF UNSTEADY TWO-LAYERED PULSATILE BLOOD FLOW IN A STENOSED FLEXIBLE ARTERY: EFFECT OF PERIPHERAL LAYER VISCOSITY

open access: yesMathematical Modelling and Analysis, 2005
The present paper deals with a theoretical investigation of blood flow in an arterial segment in the presence of stenosis. The streaming blood is treated to be composed of two different layers ‐ the central core and the plasma. The former is considered to be non‐Newtonian liquid characterised by the Power law model, while the latter is chosen to be ...

Regioselective and Anisotropic Multi‐Patching of Small Microparticles via a Polymer Brush‐Assisted Microcontact Printing (µCP)

open access: yesAdvanced Functional Materials, EarlyView.
A method to fabricate anisotropic SiO2 patchy microspheres is presented using a modified microcontact printing technique. This involves a PDMS elastomer stamp with grooved surface topography, creating a confined environment for the microspheres.

Key-Indexed Channel Phase Extended Permutation for Secure Physical Layer Authentication in Correlated Sub-Channels

open access: yesIEEE Access
In this paper, we present a novel key-indexed channel phase permutation method designed to enhance the security of physical-layer (PHY) authentication in the presence of correlated sub-channels.

Self‐organized Criticality in Neuromorphic Nanowire Networks With Tunable and Local Dynamics

open access: yesAdvanced Functional Materials, EarlyView.
Memristive nanowire networks (NWNs) are shown to be electrically tunable to a critical state where specific local dynamics evaluated by multiterminal characterization are exploited as feature selection in nonlinear transformation (NLT) tasks.

The expression of visfatin in mouse ovary and its regulatory effect on IFN-γ [PDF]

open access: yesPakistan Veterinary Journal, 2014
The expression of visfatin in ovary and the changes of IFN-γ in peripheral blood were detected by the immunohistochemical method and the double antibody sandwich ELISA test method to investigate the distribution situation of visfatin in ovary and its ...

Carbon Nanotube 3D Integrated Circuits: From Design to Applications

open access: yesAdvanced Functional Materials, EarlyView.
As Moore's law approaches its physical limits, carbon nanotube (CNT) 3D integrated circuits (ICs) emerge as a promising alternative due to the miniaturization, high mobility, and low power consumption. CNT 3D ICs in optoelectronics, memory, and monolithic ICs are reviewed while addressing challenges in fabrication, design, and integration.

Nerve guidance conduit design based on self-rolling tubes

open access: yesMaterials Today Bio, 2020
The current gold standard in peripheral nerve repair is nerve autografts for bridging gaps larger than a centimeter. However, autografts are associated with a low availability and the loss of function at the donor site.
