Optomechanical electrometer based on optical mode-localization sensing
No full textThis work explores the feasibility of the optomechanical electrometer based on a novel sensing mechanism named optical mode-localization that originates from the mechanical mode-localization sensing mechanism. The electrometer is constructed by integrating coupled optical ring resonators and a suspended slot modulator on a silicon chip. The slot modulator is a Nano-Opto-Electrical-Mechanical-Systems (NOEMS) actuator that can tune the effective index and phase of the waveguide, and thus the perturbation in electrical charge can be transferred to the phase perturbation in the optical ring resonators. We use the modulator to create the mode-localization in the coupled optical ring resonators to accomplish ultra-high sensitivity charge sensing. We established an analytical approximation of the index and phase change induced by the NOEMS slot modulator using the finite element analysis (FEA), including the Casimir force, optical force, electrostatic force and pull-in effect. The modulator can be configured in different ways to make the design flexible. COMSOL Multiphysics and Lumerical are used to analyze the possible configurations. The modulating performance of the fully suspended slot configurations are thoroughly analyzed. Based on the signal flow graph analysis (Mason’s rule), analytical model of the optical mode localization based on coupled ring resonators is established. The correctness of the theoretical model is proved by Lumerical simulation. The optical mode-localization sensing has the advantages in sensitivity, accuracy, anti-aliasing and noise immunity compared with the mechanical mode localization one. The optomechanical electrometer designed from coupled ring resonators and NOEMS slot modulator is more sensitive among other on-chip electrometers in theory. We carried out few test runs to investigate the capability of the device fabrication. The specific structural releasing process based on HF vapour etching is developed for suspended waveguide. The specific ring resonators designed successfully extract the parameters of the necessary components. The scanning electron microscopy (SEM) pictures and output spectrum indicated that the surface roughness caused by fabrication imperfections would significantly affect the performance of the devices

Storage capacity of networks with discrete synapses and sparsely encoded memories
Full text linkAttractor neural networks (ANNs) are one of the leading theoretical
frameworks for the formation and retrieval of memories in networks of
biological neurons. In this framework, a pattern imposed by external inputs to
the network is said to be learned when this pattern becomes a fixed point
attractor of the network dynamics. The storage capacity is the maximum number
of patterns that can be learned by the network. In this paper, we study the
storage capacity of fully-connected and sparsely-connected networks with a
binarized Hebbian rule, for arbitrary coding levels. Our results show that a
network with discrete synapses has a similar storage capacity as the model with
continuous synapses, and that this capacity tends asymptotically towards the
optimal capacity, in the space of all possible binary connectivity matrices, in
the sparse coding limit. We also derive finite coding level corrections for the
asymptotic solution in the sparse coding limit. The result indicates the
capacity of network with Hebbian learning rules converges to the optimal
capacity extremely slowly when the coding level becomes small. Our results also
show that in networks with sparse binary connectivity matrices, the information
capacity per synapse is larger than in the fully connected case, and thus such
networks store information more efficiently
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
