Magnetic Resonance Lithography with Nanometer Resolution

open access: yes, 2015
We propose an approach for super-resolution optical lithography which is based on the inverse of magnetic resonance imaging (MRI). The technique uses atomic coherence in an ensemble of spin systems whose final state population can be optically detected ...

On the Convergence Theory of Debiased Model-Agnostic Meta-Reinforcement Learning [PDF]

open access: yesarXiv, 2020
We consider Model-Agnostic Meta-Learning (MAML) methods for Reinforcement Learning (RL) problems, where the goal is to find a policy using data from several tasks represented by Markov Decision Processes (MDPs) that can be updated by one step of stochastic policy gradient for the realized MDP.

A phase 3, single-arm, open-label study to evaluate the safety, tolerability, and immunogenicity of a 15-valent pneumococcal conjugate vaccine, V114, in a 3+1 regimen in healthy infants in South Korea (PNEU-PED-KOR)

open access: yesHuman Vaccines & Immunotherapeutics
There is an ongoing burden of pneumococcal disease in children despite the use of pneumococcal conjugate vaccines (PCVs). This phase 3, open-label, single-arm, multisite, descriptive study was designed to evaluate the safety and immunogenicity of a 3 + 1

Low-Complexity Energy-Efficient Broadcasting in One-Dimensional Wireless Networks

open access: yes, 2012
In this paper, we investigate the transmission range assignment for N wireless nodes located on a line (a linear wireless network) for broadcasting data from one specific node to all the nodes in the network with minimum energy.

Defects in the Peripheral Taste Structure and Function in the MRL/lpr Mouse Model of Autoimmune Disease

open access: yesPLoS ONE, 2012
While our understanding of the molecular and cellular aspects of taste reception and signaling continues to improve, the aberrations in these processes that lead to taste dysfunction remain largely unexplored.

Mixed Reality Architecture: a dynamic architectural topology [PDF]

open access: yes, 2007
Architecture can be shown to structure patterns of co-presence and in turn to be structured itself by the rules and norms of the society present within it.

Enhanced Functional Recovery in MRL/MpJ Mice after Spinal Cord Dorsal Hemisection

open access: yesPLoS ONE, 2012
Adult MRL/MpJ mice have been shown to possess unique regeneration capabilities. They are able to heal an ear-punched hole or an injured heart with normal tissue architecture and without scar formation. Here we present functional and histological evidence

Optimization of magnetic contrast layer for neutron reflectometry [PDF]

open access: yesarXiv
Neutron reflectivity is a powerful technique for probing density profiles in films, with applications across Physics, Chemistry, and Biology. However, challenges arise when dealing with samples characterized by high roughness, unknown scattering length density (SLD) with low contrast, very thin layers, or complex multi-layered structures, that cannot ...
