Abstract:
We recently reported the first complete set of molecular-scale logic gates based on deoxyribozymes. Here we report how we tile these logic gates and construct new logic elements: OR, NAND, and the first element with four inputs (i1^i5)V(i2^i6). Tiling of logic gates was achieved through a common substrate used for core deoxyribozyme; degradation of this substrate defines the output. This kind of connection between logic gates is an implicit- OR tiling, because it suffices that one componenet of the network is active for the whole network to give an output of 1.

Abstract:
This paper proposes a GateRL that is an automated circuit design framework of CMOS logic gates based on reinforcement learning. Because there are constraints in the connection of circuit elements, the action masking scheme is employed. It also reduces the size of the action space leading to the improvement on the learning speed. The GateRL consists of an agent for the action and an environment for state, mask, and reward. State and reward are generated from a connection matrix that describes the current circuit configuration, and the mask is obtained from a masking matrix based on constraints

Abstract:
The architectures of integrated logic and memory devices have shifted from 2D to 3D layouts, enabling a continued scaling of device densities. Atomic layer deposition (ALD) allows the conformal deposition of thin films with sub-nm thickness control on high aspect ratio 3D structures. ALD has become the technique of choice for the synthesis of an increasing number of materials in advanced logic and memory devices. In the first part of this presentation, we briefly review some of the key ALD processes which enable the fabrication of state-of-the-art 3D-NAND and 2D-DRAM. Next, we present the ALD

The design of modular protein logic for regulating protein function at the posttranscriptional level is a challenge for synthetic biology. Here, we describe the design of two-input AND, OR, NAND, NOR, XNOR, and NOT gates built from de novo–designed proteins. These gates regulate the association of arbitrary protein units ranging from split enzymes to transcriptional machinery in vitro, in yeast and in primary human T cells, where they control the expression of the TIM3 gene related to T cell exhaustion.

Abstract:
The interest in alternative logic technologies is continuously increasing for short nanometer designs. From this viewpoint, logic gates, full adder and D-latch designs based on graphene nanoribbon field effect transistors (GNRFETs) at 7 nm technology nodes were presented, considering that these structures are core elements for digital integrated circuits. Firstly, NOT, NOR and NAND gates were implemented using GNRFETs. Then, 28T full adder and 18T D-latch circuits based on CMOS logic were designed using GNRFETs. As the first result of this work, it was shown through HSPICE simulations that the

Abstract:
Vortex beam encoded all-optical logic gates are suggested to be very important in future information processing. However, within current logic devices, only a few are encoded by using vortex beams and, in these devices, some space optical elements with big footprints (mirror, dove prism and pentaprism) are indispensable components, which is not conducive to device integration. In this paper, an integrated vortex beam encoded all-optical logic gate based on a nano-ring plasmonic antenna is proposed. In our scheme, by defining the two circular polarization states of the input vortex beams as the

RNA aptamers that bind non-fluorescent dyes and activate their fluorescence are highly sensitive, nonperturbing, and convenient probes in the field of synthetic biology. These RNA molecules, referred to as light-up aptamers, operate as molecular nanoswitches that alter folding and fluorescence function in response to ligand binding, which is important in biosensing and molecular computing.

We present a method for implementing Boolean logic operations using MQW optical devices and a spatial pattern coding. Serially connected MQW devices such as an S-SEED have some advantages: high speed switching capability, a tolerance to fluctuation of power sources, and logic operation capability. Therefore, if cascadability of logic can be maintained with these devices, we can build high speed optical logic circuits. In this study, we adopted a spatial pattern coding method, which represents logical values (1 or 0) as combinations of bright and dark cells, on both input and output sides as a

Abstract:
Graphitic Structures by Design (GSD) is a novel technology for growing graphite in precise patterns from the nano to the macroscale, rapidly (>1 layer/sec), at low temperatures (ca. 500°C), and in a single step using ordinary laboratory equipment. The GSD process consists of exposing particular metals (Ni, Pd, Pt, Co), which act as ‘templates’, to a fuel rich combustion environment. As an example, we have thoroughly characterized graphite growth on nickel in a mixture of ethylene and oxygen (O2/C2H4 ratio<3), and found that it grows in a geometry remarkably consistent with the sh
