The growing necessity for enhanced processing capabilities in edge devices with limited resources has led us to develop effective methods for improving high-performance computing (HPC) applications. In this paper, we introduce LASP (Lightweight Autotuning of Scientific Application Parameters), a novel strategy designed to address the parameter search space challenge in edge devices. Our strategy employs a multi-armed bandit (MAB) technique focused on online exploration and exploitation. Notably, LASP takes a dynamic approach, adapting seamlessly to changing environments. We tested LASP with four HPC applications: Lulesh, Kripke, Clomp, and Hypre. Its lightweight nature makes it particularly well-suited for resource-constrained edge devices. By employing the MAB framework to efficiently navigate the search space, we achieved significant performance improvements while adhering to the stringent computational limits of edge devices. Our experimental results demonstrate the effectiveness of LASP in optimizing parameter search on edge devices. © 2024 IEEE.

The implementation of secure communication in the Industrial Internet of Things (IIoT) has made and it is a significant security concern. Identity-based generalized signcryption scheme is one among the cryptographic tools available that offers a secure way out to meet the security needs of IIoT. Our proposal is a lightweight scheme, an efficient identity-based generalized signcryption that works as an encryption signature, or signcryption scheme using only one algorithm in a standard model. This scheme is appropriate for storage-limited environments like wireless sensor networks and smart cards due to its lightweight nature. This means that it can be implemented in a range of IIoT applications where resources are limited, without compromising on security or efficiency. © The Author(s), under exclusive licence to Bharati Vidyapeeth's Institute of computer Applications and Management 2023.

Majorization theoretical approach to entanglement enhancement via local filtration

From the perspective of majorization theory, we study how to enhance the entanglement of a two-mode squeezed vacuum (TMSV) state by using local filtration operations. We present several schemes achieving entanglement enhancement with photon addition and subtraction, and then consider filtration as a general probabilistic procedure consisting in acting with local (nonunitary) operators on each mode. From this, we identify a sufficient set of two conditions for these filtration operators to successfully enhance the entanglement of a TMSV state, namely, the operators must be Fock orthogonal (i.e., preserving the orthogonality of Fock states) and Fock amplifying (i.e., giving larger amplitudes to larger Fock states). Our results notably prove that ideal photon addition, subtraction, and any concatenation thereof always enhance the entanglement of a TMSV state in the sense of majorization theory. We further investigate the case of realistic photon addition (subtraction) and are able to upper bound the distance between a realistic photon-added (-subtracted) TMSV state and a nearby state that is provably more entangled than the TMSV, thus extending entanglement enhancement to practical schemes via the use of a notion of approximate majorization. Finally, we consider the state resulting from k-photon addition (on each of the two modes) on a TMSV state. We prove analytically that the state corresponding to k=1 majorizes any state corresponding to 2≤k≤8 and we conjecture the validity of the statement for all k≥9.

Improved electrical properties of micro light-emitting diode displays by ion implantation technology

Generally, the inductively coupled plasma-reactive ion etching (ICP-RIE) mesa technology was used to remove p-GaN/MQWs and expose n-GaN for electrical contact in a fabricated micro light-emitting diode (μLED). In this process, the exposed sidewalls were significantly damaged which result in small-sized μLED presenting a strong size-dependent influence. Lower emission intensity was observed in the μLED chip, which can be attributed to the effect of sidewall defect during etch processing. To reduce the non-radiative recombination, the ion implantation using an As+ source to substitute the ICP-RIE mesa process was introduced in this study. The ion implantation technology was used to isolate each chip to achieve the mesa process in the μLED fabrication. Finally, the As+ implant energy was optimized at 40 keV, which exhibited excellent current–voltage characteristics, including low forward voltage (3.2 V @1 mA) and low leakage current (10–9 A@− 5 V) of InGaN blue μLEDs. The gradual multi-energy implantation process from 10 to 40 keV can further improve the electrical properties (3.1 V @1 mA) of μLEDs, and the leakage current was also maintained at 10–9 A@− 5 V. © 2023, The Author(s).

In the last decade, Convolutional Neural Networks (CNNs) have been the de facto approach for automated medical image detection. Recently, Vision Transformers have emerged in computer vision as an alternative to CNNs. Specifically, the Shifted Window (Swin) Transformer is a general-purpose backbone that learns attention-based hierarchical features and achieves state-of-the-art performances in a variety of vision tasks. In this work, for the first time, we design and experiment transformer-based models for mass detection in digital mammograms leveraging Swin transformer as a backbone multiscale feature extractor. Experiments on the largest publicly available mammography image database OMI-DB yield a True Positive Rate (TPR) of 75.7 % at 0.1 False Positives per Image (FPpI) for the best transformer model, with 2.5 % TPR improvement over its convolutional counterpart and a massive 7.4 % TPR over the state-of-the-art. We also combine transformer- and convolution-based detectors with weighted box fusion, achieving an additional 2.4 % TPR improvement reaching 78.1 % TPR at 0.1 FPpI. © 2023, The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.

Binary Codes for Correcting Asymmetric Adjacent Transpositions and Deletions

引用

IEEE Transactions on Communications 2024年第6期73卷 3735-3749页

Codes in the Damerau-Levenshtein metric have received some attention by the research community recently owing to their applications in DNA-based data storage. In particular, Gabrys, Yaakobi, and Milenkovic (2017) designed a length-n code correcting a single deletion and s adjacent transpositions with at most (1+2s) log n bits of redundancy. In this work, we consider a new setting where both deletions and asymmetric adjacent transpositions may occur. For asymmetric transpositions, at most s+ 0-right shifts (i.e., 01 → 10) and at most s- 0-left shifts (i.e., 10 → 01) may occur. We present several constructions of the binary codes correcting these errors in various cases. In particular, we design a code correcting a single deletion, s+ right-shift, and s- left-shift errors with at most (1 + s) log(n + s + 1) + 1 bits of redundancy where s = s+ + s-. In addition, we investigate uniquely-decodable codes correcting t 0-deletions and s adjacent transpositions with at most (t + 2s) log n + o(log n) bits of redundancy. Then, we study the code for correcting t 0-deletions, s+ right-shift, and s- left-shift errors with list-decoding algorithms. Our main contribution here is the construction of a list-decodable code with list size O(ns) and with at most (max{t, s + 1}) log n + O(1) bits of redundancy, where s = s+ + s-. We construct non-systematic codes for correcting tb blocks of 0-deletions with l-limited magnitude and s adjacent transpositions with redundancy at most (2(tb+2s)+1) log(n+1)+O(1) bits and systematic codes with at most ((2(tb + 2s) + 1)(1 + 1/(log(tbl + 4))) log(N + 1) + O(log log N) redundant bits in an N-length codeword. © 1972-2012 IEEE.

Uncovering the mathematical structure of unknown chaotic systems from limited time series data poses a significant challenge in the field of dynamical systems, with broad applications across various domains. In this paper, we propose a swarm intelligence approach to tackle this issue, specifically focusing on one-dimensional discrete maps. Our approach leverages the firefly algorithm, a popular nature-inspired metaheuristic, known for its optimization capabilities. We assess the performance of the method by applying it to two illustrative examples of time series derived from one-dimensional maps: the Hénon map and the Burger map. The results show that this approach is promising for recovering the equations of motion of one-dimensional chaotic maps, even in situations where no additional information is available beyond the provided data points. © 2024 IEEE.
