BASSET: Bandpass-adaptive Single-pulse Search Toolkit—Optimized Subband Pulse Search Strategies for Faint Narrowband Fast Radio Bursts

open access: yesThe Astrophysical Journal Supplement Series
The existing single-pulse search algorithms for fast radio bursts (FRBs) do not adequately consider the frequency bandpass pattern of the pulse, rendering them incomplete for the relatively narrow-spectrum detection of pulses.

Scalable Platform Enabling Reservoir Computing With Nanoporous Oxide Memristors for Image Recognition and Time Series Prediction

open access: yesAdvanced Intelligent Systems, EarlyView.
The approach of physical in materia computing incorporates parallel computing within the medium itself. A scalable and energy‐efficient, oxide‐based computational platform is realized in form of a nanoporous network of volatile niobium oxide memristors sandwiched between top and bottom metallic electrodes, and then tested for prediction and ...

Rewiring Droplet Interface Synapses

open access: yesAdvanced Intelligent Systems, EarlyView.
Droplet interface synapses are used to create a neuromorphic network. Voltage pulses draw the droplets into contact and enable rewiring of the network through electrowetting. Results show that the heterogeneous droplet compositions and pore‐forming molecules may be used to tune the neuromorphic properties of the device using trapped charge as a form of

MLody—Deep Learning–generated Polarized Synchrotron Coefficients

open access: yesThe Astrophysical Journal Letters
Polarized synchrotron emission is a fundamental process in high-energy astrophysics, particularly in the environments around black holes and pulsars. Accurate modeling of this emission requires precise computation of the emission, absorption, rotation ...

The Determination of Precise Coordinates for Bohyunsan Optical Astronomy Observatory by GPS [PDF]

open access: yesJournal of Astronomy and Space Sciences, 1995
We determined three dimensional precise WGS 84 coordinates if two points in Bohyunsan Optical Astronomy using the GPS. One if the two points is the center on the top of pier for 1.8m telescope, and the other one is placed on the hill beside the dome of 1.
