A DESOBEDIÊNCIA COMUNAL ENTRE ARTE, FILOSOFIA E EDUCAÇÃO
Authors: Kussler Leonardo Marques
Published: August 2024

No presente artigo, discuto acerca do comum em sua relação com filosofia, arte e educação. Para isso, na primeira seção, tento mostrar que o conceito de desobediência vai muito mais além do que uma mera contestação às leis vigentes, podendo ser compreendida, de forma mais ampla, como um modus existendi crítico e comunitário. Na segunda seção, adenso a discussão acerca do comum enquanto fundamento relacional e relato algumas atividades que realizei em um projeto de pesquisa nas áreas de Educação e Artes. Por fim, defendo a hipótese de que é possível praticar a desobediência a partir de um tipo de performance filosófica, que une sujeitos e distancia-se do individualismo digital contemporâneo.

Published: August 2024

Posterior lumbar fusion surgery is a well-established procedure for treating degenerative lumbar spine diseases. Despite its surgical success over the decades, adjacent segment degeneration persisted as a problem, causing significant morbidity in patients. Various surgical fusion techniques, including open and minimally invasive procedures, have been reported for treating adjacent segment disease. Recently, endoscopic lumbar interbody fusion, including fully endoscopic lumbar interbody fusion through the uniportal approach and biportal endoscopic transforaminal lumbar interbody fusion (BE-TLIF), has been attempted as a minimally invasive surgical technique for lumbar fusion. This study describes the BE-TLIF technique and presents a review of the literature on this technique for treating adjacent segment disease. Our case illustration demonstrates that BE-TLIF could be a viable minimally invasive technique for addressing adjacent segment disease in revision lumbar spinal fusion surgery.
XLNet-LSTM-CNN for Text Sentiment analysis
Authors: Wang Yiwen , Wu Yonghong
Published: August 2024

Given the burgeoning popularity of social media and online commenting platforms, the significance of text sentiment analysis has been exponentially amplified. Deep learning is being extensively employed for text sentiment analysis, with CNN(Convolutional Neural Network) and LSTM(Long Short-Term Memory Network) showcasing remarkable capabilities. CNNs adeptly extract localized features of text, while LSTMs retain information across longer textual spans. These are often synergistically used for text sentiment classification tasks in tandem with static word vector techniques, for instance, word2vec. We propose a novel text sentiment classification model, designated as XLNet-LSTM-CNN, amalgamating the strengths of CNN and LSTM with the XLNet model. This hybrid model addresses the constraints of static word vector techniques such as word2vec, including their inability to glean deep information about the text or discern the polysemy of words. We further bolster the robustness of our model through data augmentation methods. We evaluated the performance of our proposed XLNet-LSTM-CNN model using three distinct English movie review datasets (IMDB, MR, and SST), comparing it with seven other prevalent neural network models(SVM, CNN, RNN, LSTM, BiLSTM, CNN-LSTM, and CNN-attention-LSTM). Our experimental findings revealed that the XLNet-LSTM-CNN model not only attains superior accuracy but also minimizes the loss rate and augments the model's generalization capacity compared to the competitor models. In summation, our proposed model provides a robust solution for text sentiment classification, holding immense potential for wide-scale application in text sentiment analysis on social media and online commenting platforms.

The goal of the research was to improve photocatalytic activity of WO3 by Cu doping to use for tetracycline decomposition. Firstly, the Cu dopant worked as nuclei for the crystallization of WO3 leading to an increase in growth and sizes of formed crystals. However, the incorporation of Cu dopants in the WO3 induced significant deviation into the WO3 lattice inhibiting agglomeration of the WO3 crystals to form large particles. Therefore, the crystal sizes of Cu-WO3 were bigger than the WO3 crystals, however, the Cu-WO3 particles compared to WO3 particles were smaller. By existing in the WO3 lattice, the Cu dopant created an intermediate band to decrease band-gap energy and to boost electron-hole separation of the WO3. Therefore, the synthesized Cu-WO3 effectively generated large electrons and holes for the decomposition of tetracycline under visible light excitation. The study investigated that 3Cu-WO3, in which the Cu doping ratio was 3% mole, showed the highest tetracycline decomposition efficiency (∼79.5%). This was due to the doping of Cu into the WO3 lattice reached a limit, excess that limitation, Cu precursor formed CuO distributing on the WO3 surface to eclipse light reaching the material leading to decrease in electron-hole separation rate due to limited light absorption or decrease in photocatalytic degradation. Finally, the Cu-WO3 exhibited novel stability during the degradation of tetracycline.

Published: August 2024

In the present study combustion synthesized TiO2 nanoparticles were wet impregnated with Ni, Co and Ni-Co, respectively. The photocatalytic performance of synthesized catalysts was evaluated against Malachite Green dye. The synthesized materials were characterized for crystallite size, surface morphology, elemental composition, and band-gap using X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, and ultra-violet diffused reflectance spectroscopy, respectively. The optimum parameters for maximum degradation were found by examining the effects of catalyst loading, initial dye concentration and light intensity. A comparative analysis of Ni-doped, Co-doped, and Ni-Co-doped TiO2 photocatalysts was conducted. The results indicate superior photocatalytic activity of Ni-Co doped TiO2 among the catalysts investigated under UV light. The degradation kinetics was studied and the underlying degradation mechanism is proposed with the help of LC-MS analysis. Furthermore, a comparative study on the degradation under solar radiation using Co-Ni/TiO2 was conducted.

Authors: Wu Zhan , Wang Chunxiao , Cha Sina
Published: August 2024

In order to address the carbon emissions generated by the plantation industry in China, this study used panel data from 30 provinces between 2012 and 2022 to predict and analyse the carbon emissions from the plantation industry through the LightGBM algorithm and SHAP. In addition, the hyper-parameters of the LightGBM regression model were optimised through a Bayesian optimisation algorithm and a five-fold cross-validation was applied to check the robustness of the machine learning regression model results. Finally, the SHAP model was used to analyse in depth the key factors affecting carbon emissions in the plantation industry and to explore ways to promote carbon emission reduction in China's plantation industry. The results show that agriculture-related financial expenditure, the number of agricultural high-tech enterprises and the number of rural professional cooperatives have negative effects and non-linear characteristics on carbon emissions from China's plantation industry. The LightGBM regression prediction model optimised by Bayesian algorithm outperforms the benchmark machine learning algorithm, and the R2 mean value of the five-fold cross-validation is 0.982. The results of this study can provide scientific basis and technical support for promoting the sustainable development of Chinese agriculture.

The COVID-19 vaccinations have played a significant role in controlling the pandemic. To elucidate their impact on the immune system, a COVID-19 vaccination atlas was developed through an integrative systems vaccinology approach. The atlas includes both healthy individuals and those infected with or without prior vaccination, and covers the administration of five vaccines in different regimens: Covilo®, Zifivax®, Vaxzebria® or Covishield®, Spikevax®, and Comirnaty®. Critical markers were identified to discriminate the different types of vaccines and infection, in which infection was associated with GATA3, ZNF3, KMT2A, ASXL1, SP100, and GZMM, and vaccine types were marked by ITGAM, ACTG1, LGALS3, and STAT5B. Additionally, the immunological signatures of heterologous vaccination and infection were described, and it was also shown how a full vaccination regimen markedly limited the shift of immune responses during natural infection, thereby constraining disease progression. Finally, the common transcripts shared across COVID-19 vaccines and vaccines against other pathogens were described.

Authors: Waldron Emily , Wakefield Katherine , O'Neill Desmond
Published: August 2024

Purpose Cultural gerontology – understanding ageing through the lens of arts and humanities - has emerged as an important element of epistemology of ageing. As a boundary area between geriatric medicine/gerontology and arts/humanities disciplines, joint-working/interdisciplinarity is desirable. This project aims to assess the degree of joint-working manifested in cultural gerontology by authorship and acknowledgements in papers dedicated to cultural gerontology in five journals.Methods Observational survey of authorship in 5 journals from the founding of the specific sections on cultural gerontology or specific dedicated journals, assessing number of authors, disciplinary identities, and evidence of joint working within cultural gerontology.Results Of 591 papers, 481 (81%) were single authors. There was a spread of disciplinary affiliations, 247 (41.8%) gerontology/age-studies, 169 arts/humanities/social sciences (28.6%) and 133 of uncertain affiliation (22.5%): only 38 papers had a clear indication of joint working across the disciplines (6.4%). In the two geriatric medicine journals, European Geriatric Medicine and Journal of the American Geriatrics Society, authorship was almost exclusively from geriatric medicine/gerontology. There was extremely limited use of acknowledgements.Conclusion Our study indicates that single authorship is the most frequent mode of peer-reviewed publishing in cultural gerontology, while acknowledging that some authors may have scholarly training in multiple fields but are listed as unidisciplinary. Leaders in the field and editors of relevant journals/section need to consider ways of encouraging and recognising joint working, through fuller descriptions of multiple affiliations, brief author biographies, fuller use of acknowledgements and consideration of brief accompanying discussant responses from complementary disciplines.

Published: August 2024

The specific aim of this study was to assess the impact of 20-year-old apple trees on the soil agronomic quality in an agroforestry system consisting of 2 rows of apple trees with 5 rows of vegetable beds in between. The effects of this system were analyzed specifically on soil microbial activity and fertility. Measurements were carried out for 2 years between 2019 and 2021 in apple tree rows (R) and in vegetable rows 1.5 m (B1), 3 m (B2) and 5 m (C) from the apple tree row. Litter quantities and soil organic matter (SOM) content were measured as well as the decomposition rates of apple tree leaf litter. Soil microbial activity was characterized by measuring (1) in-situ soil respiration and (2) basal (BR) and substrate induced respiration (SIR) under controlled conditions. The results showed that proximity to apple trees was linked to higher SOM content. The litter decomposition rate was up to 1.7-times greater under the tree rows than in vegetable beds. The amplitude of insitu soil CO2 flux variation and the maximum flux were lower under the tree rows than in vegetable beds, mainly due to lower temperature. In the vegetable beds, the maximum in-situ soil CO2 flux was attained faster in B1 than in C. Under controlled laboratory conditions, we showed that BR was significantly stronger in R, B1 and B2 than in C (5, 5, 4.7 and 3.5 µgC-CO2.h− 1.g− 1 soil DW, respectively). In addition, the soil in the apple tree rows was more sensitive to the addition of glucose (SIR) than the soil in the vegetable beds. Our results suggest that soil microbial activity was more intensive up to 3 m from the apple trees. Globally, the results highlight the complexity of the interactions among the biotic and abiotic factors that are at the origin of the spatial heterogeneity encountered.
Wireless Blockchain based Dual Auction Method for Peer-to-Peer Energy Exchange on Microgrid
Authors: Divya G , Supraja P
Published: August 2024

Decentralized energy trading stands as a significant avenue for enhancing the utilization of Sustainable Energy (SE) resources within the Grid network, while simultaneously mitigating losses associated with extensive grid infrastructure. Four distinct dual auction scheme, including Trade Reduction, McAfee, Vickrey Clarke Groves (VCG), and Average, aim to improve the efficiency of decentralized peer-to-peer energy exchange. This research work systematically assessed these mechanisms in a range of forms of microgrid (MG). Participants can specify how much they are willing to spend on various energy modules on varying period that incorporates user priority, bidding methods, and time of use tariffs. In most MG configurations, the Average and VCG processes were shown to be the most efficient. In particular, it was discovered that the average mechanism worked best for a market-focused MG, but the VCG mechanism was mostly beneficial for trading outside of peak hours. This work provides a thorough approach that skillfully determines and suggests the best auction procedures for various MG configurations and consumption schedules, opening the door for extra effective P2P energy exchange.

Published: August 2024

We designed and synthesized cytidine 5′-O-triphosphate bearing a reactive squaramate group attached to position 5 of pyrimidine (CESQTP) and used it as substrate for polymerase synthesis of modified RNA. In vitro transcription with T7 RNA polymerase or primer extension using engineered TGK DNA polymerase were used for synthesis of RNA probes bearing one to eight reactive modifications. The squaramate moiety speficially reacts with primary amines to form stable amide bond. Thus, the reactive RNA probes underwent bioconjugations with amine-linked fluorophore or with a lysine-containing peptide. Cross-linking reactions of squaramate-modified RNA probes with RNA-binding proteins including several viral RNA polymerases or HIV reverse transcriptase proceeded with moderate to good conversions. Inhibition of RNA-depending RNA polymerases from Japanese Encephalitis virus through formation of covalent cross-link has also been observed and the cross-link was partially identified by MS/MS analysis. Thus, the squaramate-linked CTP is a useful building block for the synthesis of reactive RNA probes for bioconjugations with amines and cross-linking with lysine residues.
Towards Resilient Pipeline Infrastructure: Lessons Learned from Failure Analysis
Authors: Silva Ana , Evangelista Luís , Ferreira Cláudia , Valença Jónatas , Mendes Maria Paula
Published: August 2024

Understanding the mechanisms of pipeline failures is crucial for identifying vulnerabilities in gas transmission pipelines and planning strategies to enhance the reliability and resilience of energy supply chains. Existing studies and the American Society of Mechanical Engineers’ (ASME) Code for Pressure Piping primarily focus on corrosion, recommending inspections every 10 years to prevent incidents due to this time-dependent threat. However, these guidelines do not provide comprehensive regulation on the likelihood of incidents due to other causes, especially non-time-dependent events (i.e. do not provide any indication of the inspection frequency or the most likely time for an incident to occur). This study adopts an innovative approach adopting machine learning, particularly Artificial Neural Networks (ANNs), to analyse historical pipeline failure data from 1970 to 2023. By analysing records from the US Pipeline & Hazardous Materials Safety Administration, the model captures the complexity of various degradation phenomena, predicting failure years and hazard frequencies beyond corrosion. This innovative approach allows adopting more informed preventive measures and response strategies, offering deep insights into incident causes, consequences, and patterns. The results deliver valuable information for maintenance planning, enabling the estimation of critical times when a pipeline may be susceptible to incidents due to various factors. This study provides operators with a strategic framework to prescriptively address potential vulnerabilities, thereby promoting sustained operational integrity and minimising the occurrence of unexpected events throughout the service life of pipelines. By expanding the scope of risk assessment beyond corrosion, this study significantly advances the field of pipeline safety and reliability, setting a new standard for comprehensive incident prevention.

Published: August 2024

Population-specific genome-wide association studies can reveal high-impact genomic variants that influence traits like body-mass index (BMI). Using the Estonian Biobank BMI dataset (n=204,747 participants) we identified 214 genome-wide significant loci. Among those hits, we identified a common non-coding variant within the newly associated ADGRL3 gene (-0.18 kg/m²; P = 3.06 × 10⁻⁹). Moreover, the missense rare variant PTPRT:p.Arg1384His associated with lower BMI (-0.44 kg/m²; P = 2.5 × 10⁻¹⁰), while the protein-truncating variant POMC:p.Glu206* was associated with considerably higher BMI (+0.81 kg/m²; P = 1.5 × 10-12), both likely affecting the functioning of the leptin-melanocortin pathway. POMC:p.Glu206* was observed in different North-European populations, suggesting a broader, yet elusive, distribution of this damaging variant. These observations indicate the novel roles of the ADGRL3 and PTPRT genes in body weight regulation and suggest an increased prevalence of the POMC:p.Glu206* variant in European populations, offering avenues for developing interventions in obesity management.

Published: August 2024

Background
Immune cell infiltration has been found to be strongly associated with the occurrence and progression of intervertebral disc degeneration (IDD), and intervertebral discs (IVDs) are immune-privileged organs. This research aimed to identify novel targets for therapeutic intervention and investigate significant physiological and cellular mechanisms involved in the immune infiltration processes of IDD.
Results
CIBERSORT deconvolution analysis revealed that the levels of follicular helper T cells and M2 macrophages were significantly increased during IDD, while the levels of resting mast cells were significantly decreased. WGCNA revealed that the blue module was associated with macrophage infiltration (positive correlation 0.87, P < 0.001), of which genes, including VAMP8, TLR4, JUN, PLA2G4A, NMI, RORA, IFNGR1, IFNGR2, NINJ1, TNIP1, and CD81, were mainly enriched in macrophage activation, myeloid leukocyte activation and the Toll-like receptor 4 signaling pathway. The proportion of leukocytes in the IVD was greatest on the 14th day after puncture. Single-cell sequencing revealed the division of degenerative IVD cells into seven major cell types, annulus fibrosus cells, smooth muscle cells, fibroblasts, macrophages, monocytes, vascular endothelial cells, and NP cells, in which Jun, Cd81, Rora, Vamp8, Ninj1, and Tnip1 were strongly expressed, western blotting results in normal and degenerated nucleus pulposus cells (NNP and DNP) showed that the expression of VAMP8 and c-Jun increased after 24 hours of stimulation with 50 ng/ml TNF-α. The immunohistochemical results showed an increase in VAMP8 and c-Jun levels in the IVD of rats on the 14th day after acupuncture.
Conclusion
The 14th day after acupuncture in the IVD of rats is a crucial time point for the infiltration of immune cells. This work is the first to reveal that VAMP8 and c-Jun are linked to the infiltration of macrophages in IDD. Elevated expression of VAMP8 and c-Jun was confirmed in both DNP and punctured rat IVDs.

Published: August 2024

Background
Exposure to compassion fatigue during internships can significantly impact on nursing students’ future career trajectories and their intention to stay in the nursing profession. Accurately identifying nursing students at high risk of compassion fatigue is vital for timely interventions. However, existing assessment tools often fail to account for within-group variability and lack predictive capabilities. To develop and validate a predictive model for detecting the risk of compassion fatigue among nursing students during their placement.
Design:
A cross-sectional study design.
Methods
Data from 2256 nursing students in China between December 2021 and June 2022 were collected on compassion fatigue, professional identity, self-efficacy, social support, psychological resilience, coping styles, and demographic characteristics. The latent profile analysis was performed to classify compassion fatigue levels of nursing students. Univariate analysis, least absolute shrinkage and selection operator regression analysis were conducted to identify potential predictors of compassion fatigue. Eight machine learning algorithms were selected to predict compassion fatigue, and the performance of these machine learning models were evaluated using calibration and discrimination metrics. Additionally, the best-performing model from this evaluation was selected for further independent assessment.
Results
A three-profile model best fit the data, identifying low (55.73%), moderate (32.17%), and severe (12.10%) profiles for compassion fatigue. The area under the curve values for the eight machine learning models ranged from 0.644 to 0.826 for the training set and from 0.651 to 0.757 for the test set. The eXtreme Gradient Boosting performed best, with area under the receiver operating characteristic curve values of 0.840, 0.768, and 0.731 in the training, validation, and test sets, respectively. SHAP analysis clarified the model’s explanatory variables, with psychological resilience, professional identity, and social support being the most significant contributors to the risk of compassion fatigue. A user-friendly, web-based prediction tool for calculating the risk of compassion fatigue was developed.
Conclusions
The eXtreme Gradient Boosting classifier demonstrates exceptional performance, and clinical implementation of the online tool can provide nursing managers with an effective means to manage compassion fatigue.

The proliferation of spintronic devices necessitates the advancement of novel material platforms, particularly those featuring ferrimagnetic and antiferromagnetic properties. Among them, NiCo2O4 (NCO), a ferrimagnetic material, stands out for its half-metallic band structure and remarkable attributes like robust perpendicular magnetic anisotropy, a high Curie temperature, and tunable film characteristics through conductivity modulation. These unique features render NCO a prime candidate for spintronics applications. Here, we focus on the orientation-dependent magnetic properties and transport behavior of epitaxial NCO films grown on (001)-, (110)-, and (111)-oriented MgAl2O4 substrates. Notably, NCO films with different epitaxial orientations exhibit significant differences in magnetic anisotropy and transport behavior. Specifically, the (110)-oriented NCO samples present a field-driven spin reorientation transition in the out-of-plane direction, resulting in a split hysteresis loop and corresponding longitudinal magnetoresistance and anomalous Hall curves. Importantly, the anomalous Hall effect (AHE) of (100) and (111)-oriented NCO films displays an opposite sign, while the AHE of (110)-oriented NCO films exhibits an unusual sign reversal at approximately 150 K, distinguishing them from other magnetic oxides. With these findings, NCO films offer a novel platform for fundamental AHE research, featuring tunable AHE signs and intriguing physical mechanisms. Additionally, by introducing an antiferromagnetic NiO layer, we achieve a significant exchange-bias effect and enhanced coercive field, holding immense potential for future spintronics applications, such as ferrimagnetic high-density memories.

To study the fatigue properties of incorporated crack HTPB (hydroxyl terminated polybutadiene propellant) propellant under strain control, fatigue tests with different strain amplitudes were carried out on the MTS fatigue testing machine. Four groups of specimens were set up in this test, namely one group with specimens and three groups with incorporated crack specimens with different angles (0°/45°/75°/ to the horizontal) of cracks. During the fatigue test, an infrared camera was used to monitor the temperature of the whole test piece in the whole process. The results show that at the same frequency, the increase of the strain amplitude will shorten the fatigue life. The fatigue life of the three incorporated crack specimens is similar reaching at 20000times, all in the same order of magnitude, and the fatigue life of the un-cracked specimen is larger reaching at 100000times, showing a cross-order phenomenon. In the fatigue test, the samples exhibit obvious strain hysteresis phenomenon and has significant viscoelastic material properties, in terms of the surface temperature monitoring of the specimens, the four groups of specimens all show a trend of temperature increase, and the final surface temperature and fatigue life are positive related.

Published: August 2024

Root-knot nematodes (RKN), Meloidogyne species, are a top global threat associated with economic crop yield losses. They are difficult to detect and control, especially given the recent restrictions on environmentally harmful chemicals. Thus, there is a need for alternative solutions for sustainable RKN management, such as nematicidal plants (non-hosts or poor hosts). Despite the advanced literature, the information for nematicidal plant species, cultivars, and specific RKN species is incomplete or inconsistent. We evaluated the host suitability of 28 nematicidal plant candidates in controlled climate chambers using a susceptible tomato and pepper as controls. The assessment was based on gall and egg mass counts after one RKN cycle. All screened candidates were less infected with M. incognita, M. arenaria, and M. enterolobii than tomatoes, suggesting all the candidates are either non/ poor hosts, except Allium fistulosum. Only Tagetes patula and T. erecta were consistently non-hosts to the three RKN species. Other candidates exhibited RKN species-specificity and varied in their poor host or non-host status depending on the variety. Selected nematicidal plants were further assessed for RKN juvenile penetration and had significantly lower M. incognita penetration than tomato. However, Crotalaria juncea had significantly higher M. incognita penetration than tomato. This suggests that the tested plants inhibit root penetration of most M. incognita juveniles at the rhizosphere level while C. juncea attracts the nematodes and restricts reproduction. There is potential for most of the nematicidal plants to be used in cropping systems for sustainable integrated RKN management.

Published: August 2024

This research assessed the reliability of haunch retrofitting technique for seismic upgrade of critically damaged frames. Two 1:3 reduced scale two-story RC frames were taken under considered, which were tested previously till the near collapse state. The haunches are employed to strengthen the joint shear strength of the badly damaged joints, which are indicative of old, non-seismic, or defective joints. Damaged concrete was replaced with new high-strength concrete, and haunch-retrofitting technique was adopted to strengthen beam-column connections, in order to avoid shear hinging at joints under lateral loads. The retrofitted frames were tested through quasi-static cyclic loads in a displacement-control condition for multiple-levels of roof drifts. In order to assess the following seismic response factors: stiffness, strength, ductility, and response modification factors—lateral force-displacement capacity curves were created and examined. Hysteretic responses of tested models were analyzed to quantify hysteretic damping. The seismic performance assessment of the retrofitted frames was conducted utilizing a code-based static force approach in multiple seismic zones. The rigid haunches contributed to the over strength factor while the dissipating haunch has major contribution in energy dissipation of the retrofitted frames.
Design and Implementation of Full Adder Using Negative Differential Resistance Circuits Based on CMOS Process
Authors: Gan Kwang-Jow , Zhang Li-Cheng
Published: August 2024

We demonstrate a full adder design based on several MOS-NDR circuits connected in series and in parallel. A basic MOS-NDR circuit is made of thee standard Si-based metal-oxide-semiconductor field-effect-transistor (MOSFET) devices. By adjusting the appropriate parameters of the gate width of the MOSFET, the Λ-type negative differential resistance (NDR) characteristic can be presented in its combined current-voltage (I-V) curve. The operating principle of this 1-bit full adder is based on the theory of monostable-bistable transmission logic gate (MOBILE). The bias voltage of this circuit is a clock signal, and its output voltage is a low or high logic level determined by the relative current peak conditions of the load and driver components of the MOBILE circuit. Most of the NDR-based applications designed in the general literature use resonant tunnel diode (RTD) devices as the main components. Compared with RTD device, our MOS-NDR circuit can be designed with standard CMOS process and simulated with HSPICE. We implement this full adder using 0.18 µm standard CMOS process.
