'Jize Yan' 'Yifei Yu'] With the application of encoders in artificial intelligence and aerospace, the demand for the miniaturization and high measurement accuracy of encoders is increasing. To solve this problem, a new absolute matrix encoder is proposed in this paper, which can realize 19-bit matrix coding by…

DNA-based data storage has attracted attention because of its higher physical density of the data and longer retention time than those of conventional digital data storage^1–7^. However, previous DNA-based data storage lacked index features and the data quality of storage after a single access is not preserved…

A new class of exact-repair regenerating codes is constructed by combining two layers of erasure correction codes together with combinatorial block designs, e.g., Steiner systems, balanced incomplete block designs and t-designs. The proposed codes have the "uncoded repair" property where the nodes participating in the…

—Parity declustering allows faster reconstruction of a disk array when some disk fails. Moreover, it guarantees uniform reconstruction workload on all surviving disks. It has been shown that parity declustering for onefailure tolerant array codes can be obtained via Balanced Incomplete Block Designs. We extend this…

'Liliang Ouyang'] Title: Abstract DNA data storage has emerged as a promising information storage technology by encoding information down to base molecules. However, it remains a challenge to structure the DNA data with ease of recording, retrieving, and reading. Here, a primer-disk-enabled hierarchical DNA data…

'Shengyong Li'] In this paper, a novel portable hard-disk encryption/decryption system with a MEMS coded lock is presented, which can authenticate the user and provide the key for the AES encryption/decryption module. The portable hard-disk encryption/decryption system is composed of the authentication module, the USB…

Confocal microscopy is an invaluable tool for 3D imaging of biological specimens, however, accessibility is often limited to core facilities due to the high cost of the hardware. We describe an inexpensive do-it-yourself (DIY) spinning disk confocal microscope (SDCM) module based on a commercially fabricated chromium…

In this communication we report our investigations into the control and monitoring of temperature in a 3D printed circular disk reactor (CDR) for continuous flow photochemistry using datalogging via a Raspberry Pi microprocessor. A lamp base and holder were designed and realised using 3D printing to enable efficient…

'Stephan ten Brink'] Abstract—It is well known that to fulfill their full potential, the design of polar codes must be tailored to their intended decoding algorithm. While for successive cancellation (SC) decoding, information theoretically optimal constructions are available, the code design for other decoding…

'Claude D’Amours' 'Halim Yanıkömeroğlu'] Abstract—In this paper, a code-domain nonorthogonal multiple access (NOMA) technique based on an algebraic design is studied. We propose an improved low-density spreading (LDS) sequenc e design based on projective geometry. In terms of its bit erro r rate (BER) performance, our…

Virtual screening using molecular docking is now routinely used for the rapid evaluation of very large ligand libraries. As such, it has become an increasingly common approach in early-stage drug discovery. These screenings generate large amounts of data proportional to the size of the compound library used, which must…

Binary self-orthogonal codes and balanced incomplete block designs are two combinatorial configurations that have been much studied because of their wide areas of application. In this paper, we have shown the distribution of (16, 6, 3)-designs in binary (25,12) selforthogonal codes. The paper also presents the…

Concurrent coding is an encoding scheme with ‘holographic’ type properties that are shown here to be robust against a significant amount of noise and signal loss. This single encoding scheme is able to correct for random errors and burst errors simultaneously, but does not rely on cyclic codes. A simple and practical…

In the field of mid-infrared (m-IR) applications, there is a need to control thermal radiation from metal-insulator-metal (MIM) metasurfaces without any optical components. Here, we introduce the concept of metalens for the MIM metasurfaces. The finite difference time domain (FDTD) simulation was used to design the…
