Neurons in area MT of primate visual cortex encode the velocity of moving objects. We present a model of how MT cells aggregate responses from V1 to form such a velocity representation. Two diierent sets of units, with local receptive elds, receive inputs from motion energy lters. One set of units forms estimates of local motion, while the second set computes the utility of these estimates. Out...

We denote each fully-connected layer fc(d) by its output dimension d, and volumetric convolution layer by conv3D(k, c, s) representing kernel size of k, strides of s across three spatial axes, and c channels. 2D convolutional layer is represented as conv2D(k, c, s). and the volumetric transpose convolution layer by deconv3D(k, c, s). Encoder and Generator for Aligned Shapes The variational alig...

Piezoelectric motors are used in many industrial and commercial applications. Various piezoelectric motors are available in the market. All of the piezoelectric motors use the inverse piezoelectric effect, where microscopically small oscillatory motions are converted into continuous or stepping rotary or linear motions. Methods of obtaining long moving distance have various drive and functional...

A 64 X64-bit iterating multiplier, the Stanford Pipelined Iterative Multiplier (SPIM), is presented. Tbe pipelined array consists of a small tree of 4:2 adders. The 4:2 tree is better suited than a Wallace tree for a VLSI implementation because it is a more regular structure. A 4:2 carry-save accumulator at the bottom of the array is used to iteratively accumulate partial products, allowing a p...

In this paper we present a low power temporal-difference image sensor with wireless communication capability designed specifically for imaging sensor networks. The event-based image sensor features a 64 64 pixel array and can also report standard analog intensity images. An ultra-wide-band radio channel allows to transmit digital temporal difference images wirelessly to a receiver with high rat...

Recent industry developments mark a milestone in the evolution of 64-bit computing. 64-bit computing has been around for a long time in mainframe, reduced instruction set computers (RISC), and, more recently, in Intel IA-64 Itanium® architectures. Now, 64-bit computing is being standardized and driven into volume markets by AMD and Intel in processors that are based on the mainstream x86 archit...

Andrew Odlyzko’s article “Isaac Newton and the perils of financial South Sea” (Physics Today, July 2020, page 30) is more than just a fascinating read about speculation time. It also, perhaps unintentionally, commentary on society’s assumptions scientists.Why would we expect to excel in speculation? Because his mastery mathematics complex natural systems work at Royal Mint? Perhaps. Furthermore...
