Overparenting's Consequences in Bangladeshi Society Child's Intelligence, Growth, and Creativity
Authors: Bhuiyan Md. Majidul Haque
Published: July 2022

The research paper is about parental guidance and the proper rearing method of a child to make them more creative. In the perspective of Bangladesh, children are less creative and only follow the rules and regulations of an institution. Moreover, children rearing methods are less to be followed by parents in Bangladesh. Some parents may not know about the types of parenting styles and the different characteristics of children. Furthermore, there is social deviance workforce in Bangladesh that triggers parents to be anxious about their children most of the time. Besides, class differentiation between families and children's rearing process differs by limiting knowledge and other opportunities. The job opportunities also precipitate the parents' expectancy over their children to be a better someone in the future, causing them to become stressed if they cannot achieve success according to their parents' aspirations. There is extreme competition in the primary level school as the government forcefully imposes the new examination system on children aged 8 to 15. This also increased the dropout rate, although the question method solely judges the creativity level. This research paper aims to recognize the need for parenting style and the types of children and establish proper guidance of parenting style to build a better tomorrow.

Authors: Miguel Laila M. , Nicora Chequin Renata , Cabral Elsa L. , Salas Roberto M.
Published: July 2022

Richardia is a Neotropical genus, belonging to tribe Spermacoceae, family Rubiaceae. It comprises 16 species distributed from the southeastern United States to Argentina and Uruguay. As part of the studies of the genus for the flora of the Southern Cone of South America, and particularly as a contribution to the Argentinean flora, we present here the results of the taxonomic studies obtained in this genus. The botanical collections available in both national and foreign herbaria, digitalized collections in online databases and specific literature were reviewed. As a result, two new records are presented, Richardia pedicellata for Misiones province, and R. scabra var. chacoensis for Salta, with their respective illustrations and a distribution map. In addition, lectotypes are designated for three accepted species: R. humistrata, R. pedicellata, and R. stellaris, and for the following synonyms: Richardsonia acutifolia, R. divergens, R. emetica, R. rosea, and R. sparsa. An updated key to the Richardia species of Argentina is also presented.

Authors: Charalambous Hara , Karagiannis Kostas , Karanikolopoulos Sotiris , Kontogeorgis Aristides
Published: July 2022

We present a necessary and sufficient condition for a maximal curve, defined over the algebraic closure of a finite field, to be realised as an HKG-cover. We use an approach via pole numbers in a rational point of the curve. For this class of curves, we compute their Weierstrass semigroup as well as the jumps of their higher ramification filtrations at this point, the unique ramification point of the cover.
Observational data and orbits of the comets discovered at the Vilnius Observatory in 1980–2006 and the case of the comet 322P
Authors: Włodarczyk Ireneusz , Černis Kazimieras
Published: July 2022

This article is devoted to the discovery of comets at the Vilnius Observatory together with the orbital analysis of dynamically interesting comets, namely 322P. We studied the orbital evolution of comet 322P with and without non-gravitational effects. It turned out that many of the comet’s orbital clones go into and out of retrograde orbits, sometimes repeatedly. The reason for such dramatic changes in the inclination of the orbit is the origin of comet 322P close to mean motion resonance 3:1 with Jupiter, ejecting them from there and, consequently, bringing the clones closer to the terrestrial group of planets. In this way, the clones of comet 322P enter retrograde orbits and reside there several ky to several My.
Searching for the urine osmolality surrogate: an automated machine learning approach
Authors: Topcu Deniz İlhan , Bayraktar Nilüfer
Published: July 2022

Objectives

Automated machine learning (AutoML) tools can help clinical laboratory professionals to develop machine learning models. The objective of this study was to develop a novel formula for the estimation of urine osmolality using an AutoML tool and to determine the efficiency of AutoML tools in a clinical laboratory setting.

Methods

Three hundred routine urinalysis samples were used for reference osmolality and urine clinical chemistry analysis. The H2O AutoML engine completed the machine learning development steps with minimum human intervention. Four feature groups were created, which include different urinalysis measurements according to the Boruta feature selection algorithm. Method comparison statistics including Spearman’s correlation, Passing–Bablok regression analysis were performed, and Bland Altman plots were created to compare model predictions with the reference method. The minimum allowable bias (24.17%) from biological variation data was used as the limit of agreement.

Results

The AutoML engine developed a total of 183 ML models. Conductivity and specific gravity had the highest variable importance. Models that include conductivity, specific gravity, and other urinalysis parameters had the highest R2 (0.70–0.83), and 70–84% of results were within the limit of agreement.

Conclusions

Combining urinary conductivity with other urinalysis parameters using validated machine learning models can yield a promising surrogate. Additionally, AutoML tools facilitate the machine learning development cycle and should be considered for developing ML models in clinical laboratories.

Authors: Tsakiridis Ioannis , Zerva Christina , Mamopoulos Apostolos , Kalogiannidis Ioannis , Athanasiadis Apostolos , Dagklis Themistoklis
Published: July 2022

Objectives

The purpose of this study was to determine the onset of fetal movements’ perception and to identify parameters that affect this timing.

Methods

This was a prospective cohort study including singleton pregnancies that attended routine prenatal care, in a tertiary care center, in northern Greece, between January 2020 and July 2021. We collected data on medical and obstetric history, and invited women to record the time that they perceived the fetal movements for the first time, that being the primary outcome of the study. Furthermore, we studied the associations between this timing and several obstetric and sociodemographic parameters.

Results

In total, 2,009 women participated in the study. The mean gestational age at first perception of fetal movements was 19 weeks (±1.5). This ranged from as early as 14+0–14+6 weeks (0.1%) to 24+0–24+6 weeks (0.1%). The majority of women (73.3%) reported initial perception of fetal movements between 18+0 and 20+6 weeks. Following multivariate logistic regression analysis, we found that nulliparity (OR: 2.607; 95% CI: 1.876–3.622; p<0.001), anterior placental position (OR: 1.918; 95% CI: 1.575–2.336; p<0.001), increasing body mass index (OR: 1.063; 95% CI: 1.040–1.088; p=0.001) and advancing maternal age (OR: 1.062; 95% CI: 1.040–1.084; p<0.001) were associated with a delayed perception of fetal movements. Multiparous women reported the onset of fetal movements almost one week earlier on average (18.6±1.4 weeks) compared to nulliparous (19.4±1.4 weeks; MD: 0.843; 95% CI: 0.718–0.968; p<0.001).

Conclusions

The onset of maternal perception of fetal movements is around 19 weeks and this timing may be delayed by higher maternal age, higher body mass index, nulliparity and anterior placental position.
An analytical approach for Shehu transform on fractional coupled 1D, 2D and 3D Burgers’ equations
Authors: Kapoor Mamta , Majumder Arunava , Joshi Varun
Published: July 2022

Obtaining the numerical approximation of fractional partial differential equations (PDEs) is a cumbersome task. Therefore, more researchers regarding approximated-analytical solutions of such complex-natured fractional PDEs (FPDEs) are required. In this article, analytical-approximated solutions of the fractional-order coupled Burgers’ equation are provided in one-, two-, and three-dimensions. The proposed technique is named as Iterative Shehu Transform Method (ISTM). The simplicity and accurateness of the method are affirmed through five examples. Graphical representation and tabular discussion are provided to compare the exact and approximated results. The robustness of the proposed regime is also validated by error analysis. In the present work, approximated and exact solutions are compared to verify the validity of the proposed scheme. Error analysis is also provided through which the efficiency of the proposed scheme can be assured. Obtained errors are lesser than the compared results.
Effect of CNTs and MEA on the creep of face-slab concrete at an early age
Authors: Zhao Zhifang , Xiao Cong , Fang Bo , Lu Yongjiu , Shi Tao , Zhao Zhigang , Gao Xiaofeng
Published: July 2022

The creep of face-slab concrete in a rockfill dam is critical for determining the restrained stress and cracking resistance of the concrete at an early age. In this article, the mix proportion of the face-slab concrete for a rockfill dam under construction without any cracking resistance additive was taken as the reference concrete (called JC) mix proportion. The carbon nanotubes (CNTs) and magnesium oxide expansion agent (MEA) were incorporated into JC to prepare face-slab concretes called NC and PC, respectively. The temperature–stress tests under temperature matching curing (TMC) and constant temperature curing (CTC) modes were conducted on these three kinds of concretes to investigate the effects of CNTs and MEA on the early-age creep properties of the face-slab concrete under variable stress conditions. The results showed that the creep performance of NC concrete under CTC mode was lower than that under TMC mode. Combined with mercury intrusion porosimetry test results, the mechanism of the effect of CNTs and MEA on creep was analyzed. The results showed that the temperature change may lead to the CNTs debonding from the cementitious matrix or matrix cracking for the NC concrete. The incorporation of CNTs can increase the early-age creep and improve the cracking resistance of concrete.
Application of MXene as a new generation of highly conductive coating materials for electromembrane-surrounded solid-phase microextraction
Authors: Esrafili Ali , Ghambarian Mahnaz , Yousefi Mahmood , Hosseini Sharieh
Published: July 2022

For the first time, highly conductive thickly layered two-dimensional titanium carbide (MXene) was applied as a new coating agent for electromembrane-surrounded solid-phase microextraction (SPME) of triadimenol and iprodione as two model analytes. Preparation of the desired coated electrode was carried out using electrophoretic deposition of MXene on the surface of platinum electrode. Characterization of the prepared coated electrode was conducted using scanning electron microscopy and energy-dispersive X-ray spectroscopy. The coated electrode was located inside a hollow fiber membrane impregnated by 2-nitrophenyl octyl ether as the supported liquid membrane (SLM), while an aqueous solution was injected inside the hollow fiber lumen. Separation and quantification of the analytes were carried out using a gas chromatography instrument equipped with mass spectrometric detection. The effective parameters of the microextraction procedure comprising pHs of sample solution and the acceptor phase, composition of the SLM, extraction time, and the applied voltage were optimized using one-variable at-a-time method. Under the optimal conditions, the calibration curves of the analytes were linear (R
2 > 0.9973) in the range of 0.3–250.0 and 0.5–250.0 ng mL−1 for triadimenol and iprodione, respectively. The limit of detections was determined to be 0.10 and 0.15 ng mL−1 for triadimenol and iprodione, respectively. Repeatability and reproducibility of the method were evaluated by the calculation of intra-day and inter-day relative standard deviations (%). The applicability of the method was evaluated by quantitative analysis of the model analytes in environmental water samples. Relative recoveries in the range of 87.31–102.7% confirmed that the prepared coated electrode can be considered a reliable option in electromembrane-surrounded SPME techniques.

Authors: Rozaki Zuhud , Rahmawati Nur , Relawati Rahayu , Wijaya Oki , Rahayu Lestari , Triyono  , Azizah Sofa Nur , Rahmat Ali , Jumakir
Published: July 2022

Mount Semeru is one of the most active volcanoes in Indonesia and the highest mountain in Java Island. Although the island is prone to volcanic eruptions, it is densely populated and also home to several farmers. The aim of this study is to analyze the strategies for overcoming farmers’ lives in Mount Semeru. This study involves 150 farmers who were randomly selected from terrains located at altitudes between 6 and 10 km in Mount Semeru. This study shows that farmers benefit significantly from the fertile lands resulting from volcanic eruptions. And they are highly motivated to engage in mitigation activities to reduce the impacts of eruption; therefore, they tend to participate in mitigation education or programs organized by government or private institutions. Support with the information and financial access regarding any mitigation strategies can help farmers a lot. Coordination among stakeholders to support mitigation strategies is necessary because all the parties are equally responsible for alleviating the impacts of volcanic eruptions. Any strategies for overcoming farmers’ lives in volcano areas also can be supported by community resilience.
A Blocked-Out Capital from Berenike (Egyptian Red Sea Coast)
Authors: Popławski Szymon , Kraśniewska Urszula , Mi Filippo
Published: July 2022

The article examines a blocked-out capital discovered in Berenike on the Egyptian coast of the Red Sea. The artefact was reused in a Late Antique installation just outside the courtyard wall of the main city sanctuary, the Isis Temple. Its distinctive, highly simplified form is typical of Ptolemaic influence in the area. This article places the fragment in its archaeological context, accompanied by a detailed architectural description and analysis of the phenomena of blocked-out capitals. The authors demonstrate that the capital under discussion does not represent an unfinished stonework, but rather an intentional stylization. Its simplification is most likely inspired by the form of Corinthian capital that was common in Egypt between the second and third century AD. The discovery of this capital implies that there were buildings with classical architectural traits in Berenike, a theory that has previously not been supported by the excavated remains.
Orthoamide und Iminiumsalze, CV. Umsetzungen von Orthoamiden der Alkincarbonsäuren mit Carbonsäureamiden
Authors: Kantlehner Willi , Lehmann Hansjörg , Edelmann Kai , Mezger Jochen , Frey Wolfgang
Published: July 2022

The reaction of an orthoamide derivative of phenylpropiolic acid (22a) with primary and secondary amides gives rise to the formation of a wide spectrum of reaction products. The reaction of 22a with formamide delivers a N-carbamoyl-cinnamic acid amidine, wheras the analogous reaction with methylene-diformamide leads to a ketenaminal, which is substituted in β-position by a N-formylimino group. From the orthoamide 22a and phthalimide a phthalic acid amide amidine is obtained. In contrast the reaction of diformamide with 22a affords a β-imino enamine. 2,6-Diaminopyridines can be obtained from 22a with acetamide, propionamide and butyramide in low yields. The pyridines are characterized as perchlorates. From 22a and benzamide a 4-amino-2,6-diphenylpyrimidine is obtained in low yield. In the reaction of the closely related orthoamide derivative of 4-Cl-phenylpropiolic acid 22b with benzamide are isolated as a further products two pyrimidine derivatives. A pyrimidinone and a vinylogous thiourea can be obtained from 22a and urea and thiourea, respectively.

Authors: Lin Gan , Lin Huirong , Yuan Zhen , Liu Gang
Published: July 2022

Advances in in vivo iron-based coordination assembly have enabled the simultaneous detection and treatment of iron-overload disorders. Specific interactions between local FeIII and organic ligands (e.g., indocyanine green and lecithin) facilitate magnetic resonance imaging with enhanced sensitivity and photoacoustic imaging with high contrast, thus overcoming the longstanding limitations of traditional iron quantification approaches. Moreover, enhanced iron depletion can also be achieved in murine genetic models of iron-overload disorders. These advances provide great promise in interdisciplinary leveraging of biology, medicine and materials science to design nanomedicines for addressing unmet clinical needs.

Which Matters More, Cognitive or Non-cognitive Ability?
Authors: Zhou Longjun
Published: July 2022

From a psychological perspective, both cognitive and non-cognitive abilities are significant drivers of human growth. The ability to gather, choose, and comprehend information is referred to as cognitive ability. To be more specific, it consists of human abilities to comprehend the nature and characteristics of objects, as well as how they relate to one another, fundamental laws, and the future course of the world. Any skill that is not cognitive is considered non-cognitive. Examples include emotional maturity, empathy, and interpersonal skills, which are essential for people to deal with various contexts.

Dimensions of Body Image: Body Image Scale
Authors: SAYLAN Ezgi , SOYYİĞİT Vesile
Published: July 2022

This study aims at developing a measuring instrument of which validity and reliability for measuring the body images of individuals during adolescence and young adulthood are proven. The study group consists of 384 high school students. The content validity of the study was tested by seeking an expert opinion and the construct validity was tested by applying explanatory (EFA) and confirmatory (CFA) factor analysis. In the scope of analysis, IBM SPSS Statistics v20.0 and Lisrel 8.80 programs were used. As a result of EFA, a four-factor structure, which explains 62% of the total variance and is composed of 21 items, was obtained. The factors were called “Negative Perception of the Body”, “Evaluation Sensitivity”, “Positive Perception of the Body”, and “Body Change”. As a result of CFA, it was determined that the four-factor structure consisting of 21 items had an adequate fit index. As a consequence of reliability analysis, it was found that the Cronbach Alpha internal consistency coefficients, calculated for EFA and CFA samples, being .92 and .88 fell within acceptable values. The findings obtained following the item analysis demonstrated that the total score of items listed in the Body Image Scale presented a high level of predictive power and distinctiveness. The Body Image Scale can be defined as a valid and reliable measuring instrument to be used to measure the body image of adolescents and young adults.
Adaptation of COVID-19 Rumination Scale (C-19RS) to Turkish: Rumination and Burnout During COVID-19 Pandemic
Authors: BOZKUR Binaz , KIRAN Binnaz
Published: July 2022

The aim of this study is to adapt the COVID-19 Rumination Scale to Turkish and to examine whether the level of COVID-19 rumination differs according to demographic variables and burnout levels. There were 835 participants in the study. The findings revealed that the adapted scale is a valid and reliable tool. In addition, it has been found that COVID-19 rumination is significantly higher in women, those who have lost income and lost acquaintances/relatives (human), those who have active COVID-19 patients from their acquaintances/relatives, and those with high burnout levels. The results of this research are important in terms of revealing the target group for intervention or preventive studies to reduce rumination related to COVID-19. In addition, considering that rumination related to COVID-19 is higher in people with high levels of burnout, it is thought that interventions to reduce rumination may also help reduce burnout.

Models of Super Dense Structures using a New Form of the Mass Function
Authors: Tamta Ritu , Fuloria Pratibha , Tamta Pramesh
Published: July 2022

In the present article, we perceive a new kind of mass function to solve Einstein's field equation and generate spherically
symmetric models of ultra-dense stellar objects. By assuming a suitable form of mass function, we study the out-march of
all physical parameters within the anisotropic fluid spheres. We find that the radial and transverse pressures, the density of
matter, redshift, mass function are regular and well behaved inside the compact fluid spheres. Our model is stable under
the action of hydrostatic, anisotropic, and gravitational forces and the causality condition is well satisfied inside the fluid
spheres. The graphical representation of the adiabatic index reconfirms the stability of our model and the compactness
parameter lies within the Buchdahl limit. The newly obtained solution is free from any singularity and satisfies all energy
conditions, i.e., strong energy condition, weak energy condition, and null energy condition. We construct models of compact
stars 4U 1820-30 and SAX J 1808-4-3658(SS2) and explore several physical features of the models.
Optimizing and Recuperating the Leakages in Low Voltage CMOS Circuits
Authors: Patel Ambresh , Sadiwala Ritesh
Published: July 2022

With the advancement of technology, small and handy electronic devices are built with low supply voltage and lower power dissipation in designing deep submicron static CMOS circuits. Small devices scaling down with burst-mode type integrated circuits have two major challenges: area and power dissipation. This paper presents a method for decreasing dynamic power, area, and leakage of application-specific integrated circuits without sacrificing performance. The High Threshold Leakage Control Transistor, TG-Based Technique, Supply Voltage Scaling, Sleep Transistor approaches are covered, and a dynamic CMOS architecture with stack transistor. With certain area and delay considerations, these strategies are utilized to diminish both types of power dissipation in the CMOS logic designs.

Authors: Patel Bhavik , Shah Bharat J
Published: July 2022

Progressive collapse is described as the removal or damage of one or more primary load carrying elements of the structures leading to the partial or full collapse of structures. For assessment of resistance towards collapse, various methods have been found in good literature and guidelines like alternate path method, strengthening or enhancement in local elements, strengthening of the girders, truss formulation at upper-level storey etc. In the present study, attempts have been focused on the contribution of brick infill walls on building resistance to collapse with different opening ratios. Three buildings structures have been considered in the present study having 4-storey, 7-storey and 10-storey (bare frame) with removal cases of four columns on at a time. The worst column removal scenario has been considered to check the influence of brick infill wall panels with different opening ratios. The structure is designed as per relevant IS codes and masonry work for brick infill have been considered with first class bricks. The present study recommends the enhancement factor for the contribution of brick infill wall panels for collapse resistance assessment of bare RC frame structure.

Recent advancements in the field of wireless sensor networks and the internet of things market give rise to security concerns. While using the application of these technologies in the real world, many security issues have emerged. There are security risks involved in using IoT and WSN devices in areas such as financial, health, and business, as well as in industry. Security requirements are exponentially increasing with the demand for IoT devices in the market around the world. The trends have shown that the WSN field is slowly merging into the IoT ecosystem. Another factor that encourages the integration of the WSN field in IoT is advancements in addressing and the internet of everything. If we study both technologies in minute detail, we will find that although both technologies are interrelated, there is a huge difference in application areas, connectivity issues, routing issues, security issues, etc. WSN gives great importance to the efficient management of constrained resources. On the other hand, security, scalability, quality of service, and heterogeneity are the main concerns in IoT systems. In this paper, there is a detailed analysis of several factors, requirements, and trends in the advancement of both technologies.
Graph-based Mechanism to Prevent Structural Attack over Social Media
Authors: Patel Jitendra , Pippal Ravi K.S
Published: July 2022

Social media sites contain the personal information of the users, which entice the attackers. The attacker performs different types of attack on the social media site to get the users sensitive information. User privacy may be breached as other passive and active attacks are performed on social media sites; to prevent such a scenario, the network operator releases the data anonymized. Social media operators fetch and store social media users' data to share among various third-party consumers. The network operator releases the complete graph in anonymized and sanitized versions because the fetched information often contains sensitive data. But it does not provide a full guarantee of user privacy. This paper proposed a solution that provides a neighborhood adjacency matrix-based anonymization process for the social network graph. This anonymization process may be used to counter the neighborhood attack over the social network graph. The proposed anonymization process increases the number of isomorphic neighborhood networks by adding dummy edges in the social network graph. Therefore, a user may not be re-identified in a social network graph based on their unique neighborhood.

Authors: Karanjkar Atul V , Kumawat Rajeshwar
Published: July 2022

Nowadays, automation in the baby cradle system proved reliable and supports in effective baby monitoring. This system monitors the baby's mattresses condition, cry detection, body temperature etc., and thus provides better care for the babies. Also it makes the parents very easy to take care of the baby and experience those worry-free feelings. Especially for the professional women who are busy in their work schedules, always find scarcity of time to take care of the baby. As a concern of money, they are unable to afford a maid or nursery to look after their baby. In this paper, a local market is studied to decide the degree of automation and best suit mobile application required for the smart baby cradle. Three sensors are used such as a sound sensor for detecting the crying sound of a baby, a wet sensor for detecting the condition of mattresses, and a temperature sensor for detecting the body temperature. To make this automated cradle internet of things (IoT) based, a Blynk platform is used and this entire feature is monitored and controlled via mobile phone. An automatic swing motion of the cradle is provided using a link mechanism. Automation in the cradle allows the remote parent to take care of their baby, monitor its actions, and maintain the balance in their professional and personal lives.

Performance Evaluation of Rice-husk Ash Based Bacterial Concrete
Authors: Kokate Vishvajit B , Kumar Shashi R
Published: July 2022

The performance evaluation of bacterial concrete made with Rice Husk Ash (RHA) is presented in this paper. Concrete is the most widely used construction material on the planet, and because of its longer service life than other building materials, it is sometimes viewed as indestructible. Continuous exposure to harsh weathering, on the other hand, causes an increase in concrete porosity and, as a result, a reduction in mechanical properties. The effect of concrete permeability on porosity and porosity connection. Microbial concrete, which uses microorganisms to increase the durability and life of the concrete, has been presented. These bacteria are employed to precipitate calcium carbonate in concrete, which is extremely desired because the calcite precipitation caused by microbial activity is pollution-free and natural. Rice husk is used to substitute fine aggregate in concrete mixes of 0, 5, 10 and 15.

Purpose: Historically until date, viral pathogens remain very challenging with respect to transmission, severity, mortality and survival with respect to sub-population variances. While racial disparities in cumulative incidence (CmI) and mortality from the influenza pandemics of 1918 and 2009 implicated Blacks with survival disadvantage relative to Whites in the United States, COVID-19 currently indicates comparable disparities. We aimed to: assess COVID-19 CmI by race, determine the Black–White case fatality (CF) and risk differentials, and apply explanatory model for mortality risk differentials. Methods: COVID-19 data on confirmed cases and deaths by selective states health departments were assessed using a cross-sectional ecologic design. Chi-square was used for CF independence, while binomial regression model for the Black–White risk differentials. Results: The COVID-19 mortality CmI was disproportionate among Blacks/AA with 34% of the total mortality in the United States, albeit their 13% population size. The COVID-19 CF was higher among Blacks/AA relative to Whites; Maryland, (2.7% vs. 2.5%), Wisconsin (7.4% vs. 4.8%), Illinois (4.8% vs. 4.2%), Chicago (5.9% vs. 3.2%), Detroit (Michigan), 7.2% and St. John the Baptist Parish (Louisiana), 7.9%. Blacks/AA compared to Whites in Michigan were 15% more likely to die, CmI risk ratio (CmIRR) = 1.15, 95% CI, 1.01–1.32. Blacks/AA relative to Whites in Illinois were 13% more likely to die, CmIRR = 1.13, 95% CI, 0.93–1.39, while Blacks/AA compared to Whites in Wisconsin were 51% more likely to die, CmIRR = 1.51, 95% CI, 1.10–2.10. In Chicago, Blacks/AA were more than twice as likely to die, CmIRR = 2.24, 95% CI, 1.36–3.88. Conclusion: Substantial racial/ethnic disparities are observed in COVID-19 CF and mortality with Blacks/AA disproportionately affected across the United States.

Purpose: COVID-19, a respiratory disease caused by SARS-CoV-2 indicates subpopulation differentials in cumulative incidence (CmI) and mortality. We aimed to assess the racial/ethnic and geo-clustering in COVID-19 CmI and mortality in Delaware. Method: A cross-sectional ecologic design was used to assess COVID-19 mortality in April, May and November 2020. The binomial and poison regression models were utilized for race/ethnic and geo-clustering risk prediction, respectively. Results: As per late April, CmI remains to be flattened in DE, with the confirmed SARS-CoV-2, n=4575 (47.5 per 10,000), Sussex county (SC), n=2,114 (111.4 per 10,000), Kent county, n=728 (41.8 per 10,000) and New Castle county, n=1,701 (28.7 per 10,000). CmI was highest for Non-Hispanic blacks (NHB), 27% (n=1250) but lowest among Asian/Pacific Islanders, n=61 (1%). The disproportionate burden of COVID-19 CmI was highest among Hispanics, 100.2 per 10,000. COVID-19 cases were more prevalent among NHB (30%) and Hispanics (19%). Mortality was higher among NHB, 1.70 per 10,000 compared to Non-Hispanic whites (NHW), 1.34 per 10,000. COVID-19 mortality differed by race, with NHB relative to NHW 27% more likely to die, risk ratio (RR)=1.27, 95%CI, 0.85-1.89. Geo-clustering indicated a significant 50% increased mortality risk in SC compared to DE, incidence rate ratio (IRR)=1.50, 95%CI, 1.11-2.03.During November, the case fatality rate (CFR) in DE was 27 per 10,000, while in the US, the CFR was 25 per 10,000. Conclusions: The Delaware COVID-19 CmI indicates disproportionate burden on NHB and Hispanics; case clustering disproportionate burden in SC; and the risk of dying was highest among NHB.
