Authors: Etowa Josephine , Ghose Bishwajit , Etowa Egbe , Dabone Charles
Published: May 2023

Vaccines have been identified as a crucial strategy to control the spread of COVID-19 and reduce its impact. However, there are concerns about the acceptance of vaccines within African, Caribbean, and Black (ACB) communities. Based on a community sample of ACB people in Ottawa, Ontario (n = 375), the current study aimed to use logistic regression analysis and identify factors associated with COVID-19 vaccine willingness. A multivariate analysis shows that ACB people who believed that the ACB population is at a higher risk for COVID-19 were more likely to be willing to receive the vaccine compared to those who did not (OR = 1.79, p < 0.05). ACB people who had received at least one dose of the COVID-19 vaccine were more likely to be willing to receive it in the future (OR = 2.75, p < 0.05), and trust in government COVID-19 information was also positively associated with vaccine willingness (OR = 3.73, p < 0.01). In addition, English-speaking respondents were more willing to receive the vaccine compared to French-speaking respondents (OR = 3.21, p < 0.01). In terms of socioeconomic status, ACB people with a post-graduate degree (OR = 2.21, p < 0.05) were more likely to report vaccine willingness compared to those without a bachelor’s degree. Based on these findings, we discuss implications for policymakers and directions for future research.

Published: May 2023

The implementation of green infrastructure (GI) as Nature-Based Solutions (NBS) generates positive effects on the water ecosystem service in an urban context. Practices such as bioretention cells, green roofs, rain gardens, permeable pavements, and infiltration trenches contribute to treating large volumes of runoff and providing safe spaces for populations living in highly urbanized areas. With the aim to simulate these effects, a hydrological modeling was carried out using the i-Tree Hydro Plus model, which quantified the runoff generated from precipitation events and effective transformations (NBS) to cope with runoff. Eight scenarios were developed: a baseline scenario, five future scenarios with green infrastructure, a scenario with increased tree coverage, and a scenario with increased urbanization. Our hypothesis is that NBS would reduce runoff and increase permeable flow. The analysis of the feasibility of implementing the modeled green infrastructures was carried out through consultation with local stakeholders in the micro-watershed. We found that bioretention cells decrease runoff by 5%, green roofs by 4%, rain gardens by 4%, permeable pavements by 4.5%, and infiltration trenches by 7.5% compared to the baseline scenario where runoff accounts for 32% of water balance flows. The scenario of increased tree coverage had a similar behavior to the baseline scenario, indicating that efforts in this alternative would generate a limited impact on the reduction of runoff. With increased urbanization, impermeable flow increases up to 78%, which would generate floods. Implementing NBS would be feasible since this type of initiative is included in the agenda of many regulatory instruments of urban planning in Costa Rica.

Background: COVID-19 patients with any pre-existing major cardio-vascular disease (CVD) are at the highest risk of viral infection and of developing severe disease. The pathophysiological mechanism is characterized by the viral link to angiotensin-converting enzyme 2 (ACE2) and the involvement of the endothelial system with the release of cytokines and the inflicting of direct damage to the myocardium, the induction of microthrombosis, and the initiation of alterations in oxygen diffusion. The aim of the study is to analyze the clinical course and outcomes in patients (gender-stratified) with pre-existing major CVD. Methods: Out of the 1833 (973 M/860 F) patients admitted to the Internal Medicine COVID-19 Unit of “Castelli Hospital”, Lazio, Italy, from 1 January 2021 to 31 December 2021, 600 patients (320 M/280 F) with a mean age of 77 (78.6 M/75.1 F) previously had CVD. Demographic characteristics, length of the stay (LOS) and oxygen therapy were evaluated. Results: All of the CVD COVID-19 patients underwent non-invasive ventilation (NIV). CVD was linked with increased LOS (21 days F/22 M) compared to no CVD (19 days). In total, 32.7% of total patients had major CVD. Conclusions: Timely identification and evaluation of patients with pre-existing major CVD are fundamental for adequate treatment based on gender, severity, state of illness and for risk reduction.
The Role of Fucoxanthin in Non-Alcoholic Fatty Liver Disease
Authors: Winarto Jessica , Song Dae-Geun , Pan Cheol-Ho
Published: May 2023

Chronic liver disease (CLD) has emerged as a leading cause of human deaths. It caused 1.32 million deaths in 2017, which affected men more than women by a two-to-one ratio. There are various causes of CLD, including obesity, excessive alcohol consumption, and viral infection. Among them, non-alcoholic fatty liver disease (NAFLD), one of obesity-induced liver diseases, is the major cause, representing the cause of more than 50% of cases. Fucoxanthin, a carotenoid mainly found in brown seaweed, exhibits various biological activities against NAFLD. Its role in NAFLD appears in several mechanisms, such as inducing thermogenesis in mitochondrial homeostasis, altering lipid metabolism, and promoting anti-inflammatory and anti-oxidant activities. The corresponding altered signaling pathways are the β3-adorenarine receptor (β3Ad), proliferator-activated receptor gamma coactivator (PGC-1), adenosine monophosphate-activated protein kinase (AMPK), peroxisome proliferator-activated receptor (PPAR), sterol regulatory element binding protein (SREBP), nuclear factor kappa B (NF-κB), mitogen-activated protein kinase (MAPK), protein kinase B (AKT), SMAD2/3, and P13K/Akt pathways. Fucoxanthin also exhibits anti-fibrogenic activity that prevents non-alcoholic steatohepatitis (NASH) development.

Published: May 2023

The solar electroflotation (EF) processes using saline electrolytes are today one of the great challenges for the development of electrochemical devices, due to the corrosion problems that are generated during the operation by being in permanent contact with Cl− ions. This manuscript discloses the corrosion behavior of titanium electrodes using a superposition model based on mixed potential theory and the evaluation of the superficial performance of the Ti electrodes operated to 4 V/SHE solar electroflotation in contact with a solution of 0.5 M NaCl. Additionally provided is an electrochemical analysis of Ti electrodes regarding HER, ORR, OER, and CER that occur during the solar saline EF process. The non-linear superposition model by mixed potential theory gives electrochemical and corrosion parameters that complement the information published in scientific journals, the corrosion current density and corrosion potential in these conditions is 0.069 A/m2 and −7.27 mV, respectively. The formation of TiO2 and TiOCl on the anode electrode was visualized, resulting in a reduction of its weight loss of the anode electrode.
Improved Thermo-Mechanical Fatigue Resistance of Al-Si-Cu 319 Alloys by Microalloying with Mo
Authors: Liu Kun , Wang Shuai , Hu Peng , Pan Lei , Chen X.-Grant
Published: May 2023

Thermo-mechanical fatigue (TMF) is one of the most detrimental failures of critical engine components and greatly limits their service life. In this study, the out-of-phase TMF (OP-TMF) behavior in Al-Si-Cu 319 cast alloys microalloyed with Mo was systematically investigated under various strain amplitudes ranging from 0.1–0.6% and temperature cycling at 60–300 °C and compared with the base 319 alloy free of Mo. Cyclic stress softening occurred in both experimental alloys when applying the TMF loading, resulting from the coarsening of θ’-Al2Cu precipitates. However, the softening rate of the Mo-containing alloy was lower than that of the base 319 alloy because of its lower θ’-Al2Cu precipitate coarsening rate per cycle. The Mo-containing alloy exhibited a longer TMF lifetime than the base alloy at the same strain amplitude. Microalloying 319 alloy with Mo enhanced the TMF resistance mainly by slowing the coarsening of θ’-Al2Cu precipitates and providing supplementary strengthening from thermally stable Mo-containing α-dispersoids distributed in the Al matrix. The energy-based model was successfully applied for predicting the TMF lifetime with a low life predictor factor, which agreed well with the experimentally measured fatigue cycles.

Materials and Methods: this study is a retrospective cohort study, performed on patients positively diagnosed with COVID-19. Available CRP, LDH, CK 25-OH vitamin D, ferritin, HDL cholesterol and clinical severity were recorded. The following were assessed: median group differences, association, correlation and receiver operating characteristic. Results: 381 children, 614 adults and 381 elders were studied between 1 March 2021 and 1 March 2022. Most children and adults presented mild symptomatology (53.28%, 35.02%, respectively), while most elders presented severe symptomatology (30.04%). ICU admission was 3.67% for children, 13.19% for adults and 46.09% for elders, while mortality was 0.79% for children, 8.63% for adults and 25.1% for elders. With the exception of CK, all other biomarkers showed some significant associations with clinical severity, ICU admission and death. Conclusions: CRP, LDH, 25-OH vitamin D, ferritin and HDL are important biomarkers for COVID-19 positive patients, especially in the pediatric population, while CK was mostly within normal ranges.
Water Skating Miniature Robot Propelled by Acoustic Bubbles
Authors: Song Hyeonseok , Kim Daegeun , Chung Sangkug
Published: May 2023

This paper presents a miniature robot designed for monitoring its surroundings and exploring small and complex environments by skating on the surface of water. The robot is mainly made of extruded polystyrene insulation (XPS) and Teflon tubes and is propelled by acoustic bubble-induced microstreaming flows generated by gaseous bubbles trapped in the Teflon tubes. The robot’s linear motion, velocity, and rotational motion are tested and measured at different frequencies and voltages. The results show that the propulsion velocity is proportional to the applied voltage but highly depends on the applied frequency. The maximum velocity occurs between the resonant frequencies for two bubbles trapped in Teflon tubes of different lengths. The robot’s maneuvering capability is demonstrated by selective bubble excitation based on the concept of different resonant frequencies for bubbles of different volumes. The proposed water skating robot can perform linear propulsion, rotation, and 2D navigation on the water surface, making it suitable for exploring small and complex water environments.

The low water solubility of an active pharmaceutical ingredient (aripiprazole) is one of the most critical challenges in pharmaceutical research and development. This antipsychotic drug has an inadequate therapeutic impact because of its minimal and idiosyncratic oral bioavailability to treat schizophrenia. The main objective of this study was to improve the solubility and stability of the antipsychotic drug aripiprazole (ARP) via forming binary as well as ternary inclusion complexes with hydroxypropyl-β-cyclodextrin (HPβCD) and L-Arginine (LA) as solubility enhancers. Physical mixing and lyophilization were used in different molar ratios. The developed formulations were analyzed by saturation solubility analysis, and dissolution studies were performed using the pedal method. The formulations were characterized by FTIR, XRD, DSC, SEM, and TGA. The results showcased that the addition of HPβCD and LA inclusion complexes enhanced the stability, in contrast to the binary formulations and ternary formulations prepared by physical mixing and solvent evaporation. Ternary formulation HLY47 improved dissolution rates by six times in simulated gastric fluid (SGF). However, the effect of LA on the solubility enhancement was concentration-dependent and showed optimal enhancement at the ratio of 1:1:0.27. FTIR spectra showed the bond shifting, which confirmed the formation of new complexes. The surface morphology of complexes in SEM studies showed the rough surface of lyophilization and solvent evaporation products, while physical mixing revealed a comparatively crystalline surface. The exothermic peaks in DSC diffractograms showed diminished peaks previously observed in the diffractogram of pure drug and LA. Lyophilized ternary complexes displayed significantly enhanced thermal stability, as observed from the thermograms of TGA. In conclusion, it was observed that the preparation method and a specific drug-to-polymer and amino acid ratio are critical for achieving high drug solubility and stability. These complexes seem to be promising candidates for novel drug delivery systems development.

In the context of a continuously increasing global cancer risk, the search for new effective and affordable anticancer drugs remains a constant demand. This study describes chemical experimental drugs able to destroy cancer cells by arresting their growth. New hydrazones with quinoline, pyridine, benzothiazole and imidazole moieties have been synthesized and evaluated for their cytotoxic potential against 60 cancer cell lines. 7-Chloroquinolinehydrazones were the most active in the current study and exhibited good cytotoxic activity with submicromolar GI50 values on a large panel of cell lines from nine tumor types (leukemia, non-small cell lung cancer, colon cancer, CNS cancer, melanoma, ovarian cancer, renal cancer, prostate cancer and breast cancer). This study provided consistent structure-activity relationships in this series of experimental antitumor compounds.
Intranasal Drug Administration in Alzheimer-Type Dementia: Towards Clinical Applications
Authors: Taléns-Visconti Raquel , de Julián-Ortiz Jesus Vicente , Vila-Busó Ofelia , Diez-Sales Octavio , Nácher Amparo
Published: May 2023

Alzheimer-type dementia (ATD) treatments face limitations in crossing the blood–brain barrier and systemic adverse effects. Intranasal administration offers a direct route to the brain via the nasal cavity’s olfactory and trigeminal pathways. However, nasal physiology can hinder drug absorption and limit bioavailability. Therefore, the physicochemical characteristics of formulations must be optimized by means of technological strategies. Among the strategies that have been explored, lipid-based nanosystems, particularly nanostructured lipid carriers, are promising in preclinical investigations with minimal toxicity and therapeutic efficacy due to their ability to overcome challenges associated with other nanocarriers. We review the studies of nanostructured lipid carriers for intranasal administration in the treatment of ATD. Currently, no drugs for intranasal administration in ATD have marketing approval, with only three candidates, insulin, rivastigmine and APH-1105, being clinically investigated. Further studies with different candidates will eventually confirm the potential of the intranasal route of administration in the treatment of ATD.
Insights into the Applications of Natural Fibers to Metal Separation from Aqueous Solutions
Authors: Tofan Lavinia
Published: May 2023

There is a wide range of renewable materials with attractive prospects for the development of green technologies for the removal and recovery of metals from aqueous streams. A special category among them are natural fibers of biological origin, which combine remarkable biosorption properties with the adaptability of useful forms for cleanup and recycling purposes. To support the efficient exploitation of these advantages, this article reviews the current state of research on the potential and real applications of natural cellulosic and protein fibers as biosorbents for the sequestration of metals from aqueous solutions. The discussion on the scientific literature reports is made in sections that consider the classification and characterization of natural fibers and the analysis of performances of lignocellulosic biofibers and wool, silk, and human hair waste fibers to the metal uptake from diluted aqueous solutions. Finally, future research directions are recommended. Compared to other reviews, this work debates, systematizes, and correlates the available data on the metal biosorption on plant and protein biofibers, under non-competitive and competitive conditions, from synthetic, simulated, and real solutions, providing a deep insight into the biosorbents based on both types of eco-friendly fibers.
Can Imaging Spectroscopy Divulge the Process Mechanism of Mineralization? Inferences from the Talc Mineralization, Jahazpur, India
Authors: Kumar Hrishikesh , Ramakrishnan Desikan , Jain Ronak , Govil Himanshu
Published: May 2023

Talc deposits of Jahazpur, Rajasthan, hosted by dolomite, are one of the largest high-quality talc deposits in India. In the present study, we use AVIRIS-NG datasets to study the link between the spatial pattern of talc mineralization, associated alteration minerals, and iron-oxide enrichment. It is noted that the majority of talc-bearing areas are characterized by the presence of clay minerals, such as an intimate mixture of kaolinite and muscovite, illite, dickite (indicative of phyllic and argillic alteration), and also enhanced iron enrichment. The talc-bearing zones are located adjacent to quartz-rich lithologies, and they are aligned along the Jahazpur thrust. Based on mineralogical and geological evidence, hydrothermal alteration of dolomites by silica and iron-rich fluid is proposed as major factorcontrolling talc mineralization. This study has implications for the identification of prospective zones of talc mineralization using imaging spectroscopy.
The Anatomy of Entrepreneurial Failure: Antecedents of the Performance Failure Appraisal Inventory and the Role of Social Support
Authors: Al-Alawi Alamir , Amjed Sohail , Elbaz Ahmed Mohamed , Alkathiri Nasser Alhamar
Published: May 2023

The purpose of this study is to investigate the impact of stress factors on entrepreneurial failure and to examine the relationship between prior entrepreneurial failure and future fear of failure. This study takes a novel approach by considering the moderating role of social support on this relationship. We employed the least squares–structural equation modeling (PLS-SEM) technique to analyze the responses of 162 failed entrepreneurs in Oman. Our findings demonstrate that stress factors in all four dimensions (managerial and planning elements, working capital, competitive environment, and growth and overexpansion) have a significant impact on entrepreneurial failure. Moreover, the results reveal that prior entrepreneurial failure is positively related to fear of failure. However, social support has a crucial moderating effect on the relationship between prior failure and present and future failure-related anxiety, reducing the influence of prior entrepreneurial failure on entrepreneurs’ fear of failure. This study contributes to the theoretical understanding of the antecedents and outcomes of entrepreneurial failure and offers practical implications for policymakers and practitioners seeking to promote entrepreneurship and reduce failure rates.
Design-Driven Conflicts: A Design-Oriented Methodology for Mindset and Paradigm Shifts in Human Social Systems
Authors: Nedaei Moein , Jacoby Alexis
Published: May 2023

Transformability is one of the essential attributes of social systems. To improve transformability, one should create the preconditions for strategic intervention on the underlying social structures. This paper proposes a design-driven conflict (DDC) methodology in response to the limitation of the systemic design approach by aggregating a network of allies essential for the paradigmatic shifts. The proposed methodology has more strategic implications. It starts with unfolding the actors and shared resources (phase one context mapping). It continues with defining the power relations between them, drivers, and spillovers that cause conflicts and disagreements (phase two analysis). After this, it shows how one can synthesize the commonalities and the core narratives of actors in the form of boundary objects (phase three synthesis). By using the existing narratives and the commonalities between actors as inputs for the translation phase, DDC creates the preconditions for a network of allies construction. Next, the methodology uses translation as a method, in relation to the four moments of a ‘sociology of translation’, problematization, interessement, enrolment, and mobilization, in order to gradually change the learning paradigm of the system. In the scaling-up phase (phase five), DDC proposes ways of creating a narrative platform, shedding light on how to mobilize the results of translation from the community level onto a broader social scale. The framework for the design methodology has been evaluated based on a method content analysis and by a group of experts from diverse backgrounds and disciplines. The results show, except for the efficiency of the method, which requires additional investigation in a real-life context, the efficacy and effectiveness of the method have been elaborated in a sufficient way.

Published: May 2023

In this paper, the exact order of simultaneous approximation and Voronovskaja kind results with quantitative estimate for the complex Stancu Beta operator of second kind attached to analytic functions of exponential growth in semidisks of the right half-plane are obtained. In this way, we show the overconvergence phenomenon for this operator, namely the extensions of approximation properties with upper and exact quantitative estimates, from the real subinterval \((0, r]\), to semidisks of the right half-plane of the form \(SD^{r}(0, r]=\{z\in \mathbb{C}: |z|\le r, \, 0 < {\rm Re}(z)\le r\}\) and to subsets of semidisks of the form \(SD^{r}[a, r]=\{z\in \mathbb{C}: |z|\le r, \, a\le {\rm Re}(z)\le r\}\), with \(r\ge 1\) and \(0<a<r\).

On approximating the solutions of equations by the chord method and a method of Aitken-Steffensen type
Authors: Diaconu Adrian
Published: May 2023

In [13] we have studied the existence and the convergence of iterative methods that use generalized abstract divided differences (this notion being defined there). We have indicated a construction model for these differences as well. A special place has been given to the iterative method of the chord for which we have established a convergence theorem which in the same time ensures the existence of the solution of the considered equation. We have obtained the convergence order with the value \(\tfrac{1+\sqrt{5}}{2}.\) This value is inferior to \(2,\) this last value representing the convergence order of the method of Newton-Kantorovich. This diminuation of the convergence order is the price to pay for the replacement of the Fréchet differential with the generalized abstract divided difference. In this paper we consider the issue of the improvement of the convergence order with respect to the method of Steffensen and Aitken-Steffensen or their generalizations through the method of the auxiliary sequences. This method will be presented in the paper together with the specification of the convergence order of the main sequence and the auxiliary sequences.

We present a new semilocal convergence analysis of Newton- Tikhonov methods for solving ill-posed operator equations in a Hilbert space setting. Using more precise majorizing sequences and under the same computational cost as in earlier studies such as [13]-[20], we provide: weaker sufficient convergence criteria; tighter error estimates on the distances involved and an at least as precise information on the location of the solution. Applications include Hammertein nonlinear integral equations.
FAFSA Completion: Considerations for an Extension-Led Statewide Nudge Campaign

Published: May 2023

Eight U.S. states have enacted legislation that mandates high school seniors to act on the Free Application for Federal Student Aid (FAFSA) before graduation. At least 10 other states are considering implementing similar FAFSA requirements. While proponents of the law believe it will affect postsecondary education and the workforce positively, dissenters argue that the policy is an unfunded mandate that taxes students and parents without offering adequate resources. This article synthesizes existing literature related to policy-related nudge campaigns to provide an Extension-led, cost-effective strategy to achieve the FAFSA mandate’s goal and improve citizens’ FAFSA completion behavior.

Published: May 2023

Невозможно представить образование будущего без конфиденциальности и конфиденциальных данных, которые необходимы для большинства научных учреждений. Именно поэтому защита этих данных требует внимания со стороны высшего руководства учреждения, администраторов и IT-менеджеров. Утечка данных оказывает негативное влияние на организации. Традиционные подходы к безопасности, такие как межсетевые экраны, не могут защитить данные от утечки. Системы предотвращения утечки данных (DLP) - это решения, которые защищают конфиденциальные данные от попадания в недоверенные руки. Эта статья является результатом изучения DLP-систем в качестве способа защиты интеллектуальной собственности научных учреждений, в которой также будет проводиться сравнение с другими системами безопасности и защиты данных.

It is impossible to imagine the education of the future without confidentiality and confidential data, which are necessary for most scientific institutions. That is why the protection of this data requires attention from the top management of the institution, administrators and IT managers. Data leakage has a negative impact on organizations. Traditional security approaches such as firewalls cannot protect data from leakage. Data Leak Prevention (DLP) systems are solutions that protect sensitive data from falling into untrusted hands. This article is the result of an examination of DLP systems as a way to protect the intellectual property of scientific institutions, which will also be compared with other security and data protection systems.

Introducción al Dossier Transformaciones territoriales en contextos de incertidumbre: Entre las lógicas de reproducción y apropiación del territorio
Authors: Mattioli Luisa
Published: May 2023

A medida que las ciudades adoptan la dinámica productiva globalizada, la incidencia de los cambios han seguido ciertas tendencias genéricas globales, en base a esta fase de modernización capitalista, lo que involucra una nueva dinámica económica global, aun cuando pueden asumir modalidades y alcances específicos en cada ciudad. Una nueva geografía de cobertura global da lugar a una metropolización extendida, caracterizada por estructuras policéntricas y fronteras difusas, introduciendo profundos cambios en la política urbana y en los modos de imaginar, percibir, diseñar y gestionar las ciudades. Este contexto motiva a cuestionar y a redefinir metodologías y conceptualizaciones relacionadas a la noción de Desarrollo, Planificación y el Ordenamiento Territorial considerando nuevas dimensiones y perspectivas. Es por ello que la discusión de este Dossier se centra en el territorio definido particularmente por sus procesos más que en la delimitación espacial netamente urbana.

Modeling Positional Uncertainty of Linear Features in Geographic Information Systems
Authors: Shaheen Fayez
Published: May 2023

This paper describes a probabilistic approach to model positional uncertainty of linear features in a vector-based geographic information system (GIS). Positional uncertainty is one of the components of uncertainty inherent in any object description in GIS. With a number of assumptions, the positional error of an arbitrary point on a line segment is derived based on the distribution of errors at the end points of the segment. This defines the probability density and the confidence region of a line segment and a set of indicators for the error of a line segment. The union of the confidence regions of the line segments establishes the confidence region of a linear feature. The derived uncertainty model is computationally feasible and has a great promise for efficient implementation in several GIS applications.
Maman, j’ai raté le transfert !

Je suis psychologue et j’exerce en libéral dans l’orientation de Freud et Lacan. J’ai étudié en FPP à Lyon 2 où j’interviens chaque année avec un module qui a pour titre : « Écrire en FPP, de la crampe de l’écrivain à la jouissance de la langue ». Je suis également romancière, scénariste et auteure de radio. Onze ouvrages à mon actif, dont mes trois premiers polars qui ont pour héros récurrent un certain Éric Lanester. Commandant de police judiciaire, il intervient principalement sur des meurtres en série. Au début de ses aventures, il devient subitement aveugle sur une scène de crime. Une cécité psychique, sans cause organique. Il va alors consulter une analyste afin de saisir ce qui lui arrive tout en poursuivant son enquête. Ces trois polars (À la vue, à la mort [2007], Cherche jeunes filles à croquer [2012] et Les enfants de la dernière pluie [2014]) ont été adaptés pour la télévision et c’est ce dont je vais parler dans ce texte. Le chemin de l’écrit à l’écran a été mouvementé et parfois douloureux. Je suis passée de l’enthousiasme à l’effarement, de la colère au dégoût. Et jusqu’au désespoir… C’est cette épopée qui s’étale sur près d’une décennie que je vais vous raconter, en commençant par évoquer mon rapport à l’écriture. Il me semble, en effet, que cela éclairera la manière dont j’ai accueilli et traversé l’adaptation de mes livres.
S2RNN: Self-Supervised Reconfigurable Neural Network Hardware Accelerator for Machine Learning Applications
Authors: Khalil Kasem , Dey Bappaditya , Bayoumi Magdy
Published: May 2023

Neural networks have been commonly used in different domains. Hardware implementation of the neural networks is challenging to fit different applications’ requirements. This often necessitates realizing different neural network FPGA configurations from the very scratch specific to a given application. This paper proposes a flexible method that can be reconfigured in a self-supervised way to fit several ap?plications’ requirements, by providing only maximum available computational nodes a prior. The proposed method is based on reconfiguring the required number of hidden layers and hidden nodes of that layer based on a given application. Reconfigurability also allows to decide and update the number of active nodes, at layer (l+1), which receives computational results of l th layer nodes. A configuration block is used to send a signal to the control block which follows each node output. The control block decides which following nodes receive the output according to the corresponding signal value from the configuration block. Each node receives a signal to be enabled or disabled from the configuration block. Therefore, the number of inputs of each node and nodes in each layer is determined according to the desired performance. The goal here is to automatically propose the optimal NN configuration through reconfigurability to fit different applications, to achieve the maximum accuracy possible. The optimality can be demonstrated in terms of minimum average power, average delay, and area overhead as well as maximum throughput and accuracy. The main advantage of the proposed approach is the reusability of the optimized architecture (which is self-learned online) for the very first application/dataset, as the initial configuration for any new/next dataset/application rather than starting from scratch. We have demonstrated with experimental results, the proposed approach helps primarily to significantly reduce optimized architecture search cost (the number of online training iterations) as well as associated average power consumption for successive datasets/applications. Our proposed method demonstrates its effectiveness both quantitatively and qualitatively. The proposed method is verified against two different classification problems, MNIST and CIFAR-10. Our proposed reconfigurable method demonstrates stable accuracy of 98.97% and 98.95% against the state-of-the-art neural network with two different fixed configurations as (98.85% and 73.0%) for MNIST and (93.47% and 70.21%) for CIFAR-10, respectively. The proposed method also demonstrates a 20.9% reduction in average power dissipation against the state-of-the-art method. The proposed method is implemented and tested using VHDL and Altera FPGA. The results show resource utilization is comparable with the state-of-the-art method.
