Aim. To study theoretical and methodological aspects of the phenomenon of “social innovation”.Tasks. To systematize the existing knowledge about social innovations, to identify the genesis of the concept of “social innovation”; to establish how the content of this concept has changed and in connection with what, what importance scientists assign to this concept at present.Methods. The research was carried out with the help of methods of scientific knowledge (analysis of scientific works of foreign and domestic authors in the field of economics and management, synthesis of concepts and approaches).Results. Theoretical aspects of social innovation have been studied. International and domestic works of scientists of different time periods and countries were analyzed. On the basis of the study the following definition was obtained: social innovations are innovations that are an effective tool to stimulate the solution of acute problems in society (in case of short impact), a trigger of transformations and/or a driver of economic development (in case of long impact), affecting the quality of institutions in order to improve the quality of life of people.Conclusions. Despite the fact that the concepts of “innovation” and “sociality” developed independently and independently of each other, they have always evolved simultaneously. This is evidenced by the works of thinkers of all historical epochs, starting from the Ancient World. Moreover, with the passage of time there is a scientific “splicing” of these two concepts, which becomes most noticeable at the turn of the late XIX - early XX century, when the world is experiencing significant socio-economic and political events. More and more scientists raise pressing questions about what social innovation is - a derivative or a producer, an indicator or a tool, influencing institutions or being influenced by institutions. The significance of this study lies in the attempt to systematize theoretical and methodological aspects for further study of this phenomenon.

Published: October 2023

<p>Decentralized ledger technology (DLT) is becoming ubiquitous in today's society. After an initial grassroots adoption, enterprises embrace this technology, following the opportunity to expand to new businesses - the technology is maturing. However, organizations need to connect their existing systems and processes to blockchains (centralized - decentralized) securely and reliably, sometimes also implying to connect blockchains (decentralized - decentralized). This challenge is known as blockchain interoperability.</p>
<p>Blockchain interoperability comes in three modes: data transfers, asset transfers, and asset exchanges. As blockchain interoperability is still maturing, there are many unsolved challenges across the different interoperability modes. In this \emph{position paper}, we illustrate the remaining challenges of interoperability, focusing on the systematic evaluation of interoperability mechanisms, based on the state of the art and our own experience. We first introduce the notion of cross-chain interoperability and cross-chain rules. Then, we present our survey and results. </p>
<p>We ran an online survey comprised of 17 items targeting blockchain specialists. Our quantitative analysis shows that several interesting metrics can show promising directions to evaluate integration solutions systematically. Finally, building upon our study, we propose the blockchain interoperability evaluation framework, the first step to evaluate blockchain interoperability solutions systematically.</p>

Published: October 2023

<p>Accurate trajectory prediction is vital for various applications, including autonomous vehicles. However, the complexity and limited transparency of many prediction algorithms often result in black-box models, making it challenging to understand their limitations and anticipate potential failures. This further raises potential risks for systems based on these prediction models. This study introduces the Performance Monitor for Black-Box Trajectory Prediction Model (PMTM) to address this challenge. The PMTM estimates the performance of black-box trajectory prediction models online, enabling informed decision-making. The study explores various methods' applicability to the PMTM, including anomaly detection, machine learning, deep learning, and ensemble, with specific monitors designed for each method to provide real-time output representing prediction performance. Comprehensive experiments validate the PMTM's effectiveness, comparing different monitoring methods.</p>
<p>Results show that the PMTM effectively achieves promising monitoring performance, particularly excelling in deep learning-based monitoring. It achieves improvement scores of 0.81 and 0.79 for average prediction error and final prediction error monitoring, respectively, outperforming previous white-box and gray-box methods. Furthermore, the PMTM's applicability is validated on different datasets and prediction models, while ablation studies confirm the effectiveness of the proposed mechanism. Hybrid prediction experiments further demonstrate the value of the proposed monitor from an application perspective. </p>
Automatic Speech Recognition for Nigerian-Accented English
Authors: Babatunde Oreoluwa 
Published: October 2023

<p>Automatic Speech Recognition (ASR) systems have become ubiquitous in our daily lives, powering voice assistants and transcription services. However, these systems often overlook the diverse range of accents, including Nigerian-accented English, as they are primarily developed and trained on native English accents. This research aims to address this gap by developing a Nigerian-accented English ASR system. By creating ASR models capable of accurately interpreting and transcribing Nigerian-accented English, we strive to ensure equitable access to ASR technologies and services for individuals with Nigerian accents. The study employed transfer learning techniques on NeMo’s QuartzNet15x5 English model and Wav2vec2.0 XLS-R300M using Nigerian-accented data. NeMo QuartzNet15x5Base-En exhibited the fastest inference time of 0.156 seconds with a Word Error Rate (WER) of 8.2% on the test set and Wav2Vec2 XLS-R-300M achieved a WER of 14.9% on the test set with an inference time of 1.1 seconds. This work presents the NeMo QuartzNet15x5Base-En pretrain model as best for ASR modelling especially in a low-resource regime </p>
Low-Rank Tensor Completion via Novel Sparsity-Inducing Regularizers
Authors: Wang Zhi-Yong , Cheung so Hing , Zoubir Abdelhak M. 
Published: October 2023

<p>To alleviate the bias generated by the $\ell_1$-norm in the low-rank tensor completion problem, nonconvex surrogates/regularizers have been suggested to replace the tensor nuclear norm, although both can achieve sparsity. However, the thresholding functions of these nonconvex regularizers may not have closed-form expressions and thus iterations are needed, which increases the computational loads. To solve this issue, we devise a framework to generate sparsity-inducing regularizers with closed-form thresholding functions. These regularizers are applied to low-tubal-rank tensor completion, and efficient algorithms based on the alternating direction method of multipliers are developed. Furthermore, convergence of our methods is analyzed and it is proved that the generated sequences are bounded and any limit point is a stationary point. Experimental results using synthetic and real-world datasets show that the proposed algorithms outperform the state-of-the-art methods in terms of restoration performance.</p>

Redistribution of knee and ankle joint work with different midsole thicknesses in non-rearfoot strikers during running: A cross-sectional study
Authors: Miyazaki Tomohiro , Aimi Takayuki , Nakamura Yasuo 
Published: October 2023

Purpose
To investigate the effects of midsole thickness on non-rearfoot strike runners’ redistributions of knee and ankle joint negative and positive work.
Methods
Fourteen healthy male runners wore minimalist, traditional, and maximalist shoes and ran in a straight line in each shoe in the laboratory at a speed of 15 km/h, with a ±5% difference being allowed. Whole-body kinematics and ground reaction forces were recorded, and the data of eleven non-rearfoot strikers were used for the analysis. Ankle and knee joint negative and positive work was calculated by integrating each joint's torque power. Friedman test was used for statistical comparisons.
Results
Minimalist shoes induced significantly greater ankle joint negative and positive work than in other shoes. Maximalist shoes induced significantly lower ankle joint positive work and greater knee joint negative work than in other shoes, and significantly greater knee joint positive work than in minimalist shoes.
Conclusions
Our results indicated that non-rearfoot strikers redistributed joint negative and positive work from the knee to the ankle when using minimalist shoes or from the ankle to the knee when using maximalist shoes. It is recommended that future research employs more rigorous study designs, such as randomised controlled trials and longitudinal studies, to provide a more accurate assessment of the effect of these shoes on injury rates.
Hemodynamic Impact of Snoring on Carotid Artery after Stent Implantation: The Role of Oscillation
Authors: Xianghao Zhang  , Zhenmin Fan  , Xiao Liu  , Mingyuan Liu  , Xia Ye  , Xiaoyan Deng  
Published: October 2023

Purpose
Snoring is common in overweight and old patients treated by endovascular stenting. Studies have proved a correlation between snoring and carotid stenosis, thus, snoring after carotid artery stenting (CAS) might promote or worsen clinical performance.
Methods
This study tested this hypothesis by constructing a patient-specific carotid bifurcation model and numerically analyzing hemodynamic changes of the carotid artery under different snoring conditions. These conditions included small and large amplitude, low and high frequency, and different age groups.
Results
The results found that high amplitude snoring suppressed the disturbed flow at the stented segment, while the downstream region of ICA became more chaotic, accounting for in-stent intimal restenosis and thrombosis. Furthermore, local blood flow patterns of elder groups with snoring symptoms were more likely to be changed due to low-speed flow, increasing the possibility of vascular remodeling and thrombosis. Besides, increased snoring frequency hardly influenced the local disturbed flow.
Conclusions
Therefore, older adults should receive medical treatment actively after stenting for high amplitude snoring as soon as possible to avoid potential adverse events.
