ABSTRACT Modifying the genomes of many organisms is becoming as easy manipulating DNA in test tubes, which made possible by two recently developed techniques based on either customizable binding protein, TALEN, or CRISPR/Cas9 system. Here, we describe a series efficient applications derived from these technologies, combination with various homologous donor plasmids, to manipulate Drosophila genome: (1) precisely generate genomic deletions; (2) make replacement fragment at single nucleotide...

All-reduce is the crucial communication primitive to reduce model parameters in distributed Deep Neural Networks (DNN) training. Most existing all-reduce algorithms are designed for traditional electrical interconnect systems, which cannot meet requirements training of large DNNs due low data bandwidth systems. One promising alternatives optical interconnect, can provide high bandwidth, transmission delay, and power cost. We propose an efficient scheme called WRHT (Wavelength Reused...

Current Internet of Things (IoT) embedded applications use machine learning algorithms to process the collected data. However, computational complexity and storage requirements existing deep methods hinder wide availability applications. Spiking Neural Networks (SNN) is a brain-inspired methodology that emerged from theoretical neuroscience, as an alternative computing paradigm for enabling low-power computation. Since these IoT devices are usually resource-constrained, compression...

Free-space strong-field terahertz (THz) electromagnetic pulses have emerged as a potent tool for non-equilibrium quantum state control. However, these applications predominantly rely on electric field components, with limited utilization of magnetic components. A traditional electro-optical sampling technique may encounter constraints due to the strength saturation effect when detecting THz pulses. Here we identified intense THz-induced Zeeman torque signals in CoFe and successfully detected...
