Published: April 2021

Topography and bathymetry integration is one of the essential things in providing height data. So far, the topography and bathymetry problems are the lack of height data availability, not up to date, and low vertical accuracy. The latest DTM is one of the topography data with up to date elevation with a spatial resolution of 5 m. Bathymetry extracted from SAR images. It is an alternative depth data for ocean bathymetry and inland water bathymetry. Topography and bathymetry integration is required to obtain comprehensive height data. This study aimed to integrate the latest DTM with SAR bathymetry. The method used in this integration was DEM integration. The method combined the latest DTM data with SAR bathymetry based on the correlation of the two data's standard deviation. The integration of the latest DTM with SAR bathymetry needs to consider differences in height reference fields. Two integration studies were conducted in this research-the latest DTM integration with ocean bathymetry for Rote Island. Then the integration of the latest DTM with inland water bathymetry in Lake Singkarak. The result of the integration is necessary to check the surface by generating longitudinal and cross-section profiles. Integrating the latest DTM and SAR bathymetry can be used for various mapping surveys on lands and waters.

Published: April 2021

a clayed soil characterized by reddish in colour, thick solum and neutral acidity. Farmers in Parakan area, Parigi District of Pangandaran, usually cultivate cash crops in terra rossa. Nowadays, farmers have no information about the properties of the soil, which is an important factor to maintain and increase plant productivity. The objective of this descriptive quantitative study was to verify the soil characteristic included physicochemical and microbiological properties in a selected agricultural field of Parakan. The soil samples were taken from three different areas covered with different vegetation. The study showed that terra rossa in the karst area is a non-saline soil with neutral acidity and low electrical conductivity. The texture of all soils were clay contained >50% clay particle. The soils were low in organic carbon, total nitrogen and available phosphor; but high in total phosphor and potassium, as well as cation exchange capacity. The population of soil microbes include total and fungal bacteria, as well as nitrogen-fixing Azotobacter and phosphate solubilizing bacteria, were average. In order to increase the organic carbon level; and the availability of phosphor and nitrogen, organic matter amendment is needed.

Published: April 2021

Viscosity is one of the factors affecting the performance of the centrifugal pump. A centrifugal pump is a device that used driven motor called impeller to move fluid by rotational energy. This thesis is about the analysis of the performance of the centrifugal pump when transferring viscous liquids. For this project, the objective is to design and fabricate a device that can pump liquid with various viscosity using centrifugal pump. The liquids used in the experiment are comprised of a mixture of detergent and water with different ratio to alter the viscosity. The viscosity is being identified by the usage of Zahn Cup Method with the temperature kept constant at 26 °C throughout the experiment. The performance of the centrifugal pump is being investigated by four parameters which is the flowrate, Total Dynamic Head (TDH), power and efficiency. The performance of the centrifugal pump can be accessed by altering the pump shaft speed in order to get various reading for the flow rate. In order to alter the pump shaft speed, the usage of motor with Variable Frequency Drive (VFD) is implemented. The values for the flowrate and pump shaft power are measured by flowmeter and Variable Frequency Drive (VFD). The Total Dynamic Head (TDH), hydraulic power and pump efficiency is calculated based on the reading of the flowmeter and pump shaft power displayed at Variable Frequency Drive (VFD). At the end of this project, the pump performance while pumping different viscous liquids at different flowrates is being identified.

Differentiated thyroid cancer (DTC) represents the most common form of thyroid neoplasms and is becoming increasingly prevalent. Evidence suggests a possible relationship between DTC diagnosis and subsequent atrial fibrillation (AF). If confirmed, this may present an alarming health risk (AF) in an otherwise condition with a relatively good prognosis (DTC). The aim of this systematic review and meta-analysis is to provide for the first time a pooled estimate of AF incidence in DTC patients in comparison to healthy controls. A detailed search in electronic databases, clinical trial registries and grey literature was performed to identify studies reporting the incidence of AF in DTC patients. Newcastle–Ottawa quality assessment scale was used to assess study quality. We used a random effects (RE) generalized linear mixed model (GLMM) in pooling of individual studies and also calculated a prediction interval for the estimate of a new study. Six observational studies met the eligibility criteria, which included totally 187,754 patients with DTC and 199,770 healthy controls. The median follow-up period was 4.3 to 18.8 years; the incidence rate of AF was 4.86 (95% CI, 3.29 to 7.17, I2 = 96%) cases per 1000 person-years, while the incidence rate ratio was 1.54 (95% CI, 1.44 to 1.65, I2 = 0%, 95% PI, 1.33 to 1.78).This is the first meta-analysis to confirm that patients with DTC are at a high risk for developing AF, which may be attributed to a state of iatrogenic hyperthyroidism due to long-term thyrotropin suppression therapy.

The Effects of Technology Affinity, Prior Customer Journey Experience, and Brand Familiarity on the Acceptance of Smart Service Innovations
Authors: Trautwein Stefan , Lindenmeier Jörg , Arnold and Christian
Published: April 2021

In our study, a model of smart service innovation (SSI) acceptance is delineated. We assume that the effects of the customer journey experience (CJE) and technology affinity (TA) on adoption intention (IN) are mediated by consumers’ attitudes (AT) towards the adoption of SSIs. Furthermore, contingent on the level of brand familiarity (BF), this study hypothesizes a moderated mediation with regard to the ‘CJE = AT = IN’ relationship. The empirical findings are largely in line with the model hypotheses: First, technology affinity affects adoption intention indirectly via attitude towards SSIs. Second, CJE has a significant direct and indirect effect on adoption intention in the cases of average and high brand familiarity. For low brand familiarity, CJE neither has a significant direct effect nor a significant indirect effect on SSI acceptance. Based on the empirical findings, the present paper discusses implications for service management and service research, study limitations and avenues for future research.

Authors: Madhavi Deepak , Subuhi Shamama , Zubai Mohammed
Published: April 2021

Thrombocytopenia is one of the commonest haematological disorders in the neonatal period, affecting up to a third of those admitted to neonatal intensive care units. It is well recognized that many fetomaternal and neonatal conditions are associated with thrombocytopenia. The majority of episodes of neonatal thrombocytopenia are relatively mild, self-limiting and of short duration but it may cause severe morbidity & mortality due to severe complication like IVH. Methods & material: 140 Newborn admitted in tertiary care NICU were selected to find out outcome and etiology of neonatal thrombocytopenia. Detail maternal history and neonatal physical examination done and Neonates were followed for outcome, relevant investigation done according to cases. Result: Out of 140 neonates 63 neonates had thrombocytopenia (45%).42.8% neonates were premature out of which 63.3% had thrombocytopenia. Other neonatal risk factor for thrombocytopenia are sepsis 38 (74.5%), SGA/IUGR 28(80%) and NEC 9(100%). Maternal risk factor for thrombocytopenia are eclampsia81.8% and infection during pregnancy 72.72%. 95.5 % of all study population were discharged.4.5 % cases of whole study population didnâ€™t survive. 4.54% of mild, 9.09% of moderate and 60 % of severe thrombocytopenic babies didnâ€™t survive. Conclusion: Bleeding manifestations i.e. mucosal, cutaneous and intracranial bleed were significantly associated with severe thrombocytopenia. 60% of mortality was found in severe thrombocytopenic group. Thus, severe thrombocytopenia was found to be a predictor of poor outcome in sick neonates of NICU.

Purpose. Largemouth bass (Micropterus salmoides), a fish species native to freshwaters of North America, is a promising object of aquaculture all over the world. This is evidenced by the fact that this species is currently actively cultivated in aquaculture of more than 50 countries worldwide, on all continents, with the exception of Antarctica and Australia, both for recreational fishing and as a table fish. If we consider the history of breeding and cultivation of the largemouth bass, we can note a tendency to a continuous expansion of the stages of cultivation and transition from polyculture to monoculture. For example, in the first half of the last century, fish farms in the United States raised mainly juveniles of largemouth bass for stocking to natural water bodies, but currently most farms use the full production cycle from fry to marketable fish. In addition, earlier largemouth bass was used in many countries mainly as an additional object of aquaculture (biomeliorator) to increase the production of common carp, but now, thanks to the development of recreational fishing, it is increasingly becoming the main object of aquaculture, which is facilitated by the intensification of cultivation methods. Nowadays, there are many methods of growing largemouth bass, from the simplest, extensive, when fish are raised on natural food supply, to most intensive using flow-through aquaculture systems and off-season spawning. On the territory of Ukraine, it may be effective to use pond aquaculture of largemouth bass, which begins from the production of larvae and fry at fish farms. This stage of fish farming will be discussed in this article. Findings. This article contains brief information on method of natural spawning of largemouth bass, filling ponds with water, selection of broodstock and norms for their stocking to spawning ponds, spawning behavior of fish, peculiarities of caring for larvae and fry, sorting juveniles, as well as minimizing injuries during manipulations with fish. Practical value. Information from this review can be used for development of a new method for production of largemouth bass larvae and fry at warm-water pond farms in Ukraine, taking into account climatic conditions and local specificities of aquaculture. Key words: Largemouth bass, Micropterus salmoides, recreation fishing, sport fishing, pond fish farm, aquaculture, biomeliorator, larvae, fry, polyculture, monoculture, intensification, perspective species.
A Standardized Protocol to Improve Acute Seizure Management in Hospitalized Pediatric Patients
Authors: Pavitt Sara , Carley Alison , Porter Brenda , Knowles Juliet K.
Published: April 2021

BACKGROUND:

Studies of seizure management in the pediatric inpatient setting are needed. Seizures recorded by video EEG provide an opportunity to quantitatively evaluate acute management. We observed variation in delivery of standardized seizure safety measures (seizure first aid) during epilepsy monitoring unit admissions at our hospital. Our goals were to increase consistency and speed of seizure first aid and neurologic assessment in acutely seizing patients.

METHODS:

Using a root cause analysis, we identified major factors contributing to variation in seizure management and key drivers for improvement. Targeted interventions, centered around a protocol for acute seizure management, were implemented through quality improvement methodology. The primary outcome was correct performance of standardized seizure first aid and neurologic assessment. Secondary outcomes were time intervals to each assessment. Run charts were used to analyze primary outcomes, and statistical control charts were used for secondary outcomes. Nursing confidence in seizure management was determined through pre- and postsurveys and analyzed with the χ2 test.

RESULTS:

Thirteen seizures were evaluated in the preintervention phase and 10 in the postintervention phase. Completed components of seizure first aid increased from a median of 3 of 4 to 4 of 4; completed components of neurologic assessment increased from a median of 2 of 4 to 4 of 4. Responses to acute seizures were faster, and nursing confidence increased.

CONCLUSIONS:

A collaborative quality improvement effort between physicians and nurses led to prompt and correct delivery of seizure first aid by first responders. These relatively simple interventions could be adapted broadly to improve acute seizure management in the pediatric inpatient setting.
Predictors of Prolonged Length of Stay in Suicidal Children Transferred to Psychiatric Facilities
Authors: Masciale Marina , Dongarwar Deepa , Salihu Hamisu M.
Published: April 2021

OBJECTIVES:

To determine if sociodemographic factors or underlying mental health conditions serve as predictors for prolonged length of stay (pLOS) in children hospitalized for suicidal ideation (SI) or suicide attempt (SA) requiring transfer to psychiatric facilities. We hypothesized an association between certain patient and hospital characteristics and pLOS.

METHODS:

For this retrospective cross-sectional study, we used the National Inpatient Sample. We included children <18 years old hospitalized with a primary or secondary International Classification of Diseases, 10th Edition, Clinical Modification diagnosis of SI or SA who were dispositioned to psychiatric facilities from 2016 to 2017. Exposures were patient sociodemographics, underlying mental health diagnoses, and hospital characteristics. Our outcome was pLOS. Adjusted prevalence ratios with 95% confidence intervals (CIs) were generated with log binomial regression.

RESULTS:

Of 12 715 hospitalizations meeting inclusion criteria, 5475 had pLOS. After adjusting for sociodemographics and hospital characteristics, predictive factors for pLOS were public insurance use (prevalence ratio: 1.40; CI: 1.12–1.78), urban nonteaching hospital location (prevalence ratio: 4.61; CI: 2.33–9.12), urban teaching hospital location (prevalence ratio: 3.26; CI: 1.84–5.76), and underlying diagnosis of mood disorder (prevalence ratio: 1.98; CI: 1.63–3.42). Hispanic patients had decreased probability of pLOS (prevalence ratio: 0.69; CI: 0.52–0.93). Otherwise, age, zip income, sex, and hospital region were not predictive of pLOS.

CONCLUSIONS:

Among children hospitalized for SI or SA requiring transfer to psychiatric facilities, public insurance, urban hospital location, and diagnoses of mood disorder, depression, and bipolar disorder were predictive of pLOS. Further research is needed on how to decrease disparities in length of stay among this vulnerable population.
Ear Abnormalities
Authors: Bhatti Sana L. , Daly Lauren T. , Mejia Martha , Perlyn Chad
Published: April 2021

Congenital ear abnormalities present an aesthetic and psychosocial concern for pediatric patients and their parents. Diagnosis of external ear deformities is based on clinical examination and is facilitated by an understanding of normal ear anatomy. Ear anomalies can be categorized as malformations or deformations. Malformations are characterized by absent anatomical structures of the ear (or absence of the ear itself), as exemplified by microtia and anotia. Ear deformations are characterized by ear anatomical landmarks that are present but are distorted or abnormal, with Stahl ear, constricted ear, and prominent ear being common presentations. Ear malformations will not improve with growth of the patient and uniformly require surgical intervention to recreate an anatomically typical ear. Although a small percentage of ear deformations can self-resolve, most patients with ear deformations will require nonsurgical or surgical reconstruction to achieve a normal or more aesthetic ear. In recent decades the use of nonsurgical ear splinting or molding has been recognized as a highly effective method in correcting a variety of congenital ear deformations when treatment is initiated in the first 8 weeks of life. The urgency in initiating nonsurgical treatment of ear deformations at an early age makes prompt recognition of these ear deformations essential because surgical correction remains the only viable reconstructive option in older infants and children.
Deferred Stenting for Heavy Thrombus Burden During Percutaneous Coronary Intervention for ST-Elevation MI
Authors: Pradhan Akshyaya , Bhandari Monika , Vishwakarma Pravesh , Sethi Rishi
Published: April 2021

Patients with ST-elevation MI (STEMI) usually have a huge thrombus burden in the infarct-related artery. Stenting may lead to high chances of the slow-flow/no-reflow phenomenon that leads to periprocedural MI and adverse cardiovascular events. Deferred stenting may be beneficial in this situation as the thrombus burden will reduce, mitigating the slow-flow/no-reflow phenomenon. However, routine deferral of stenting in patients with STEMI has not been found to be beneficial, but when the patient is properly selected, deferred stenting has the potential for reducing the final infarct size. The authors report the safety and feasibility of deferred stenting after 5 days of prolonged anticoagulation in a 45-year-old smoker with STEMI who had a large thrombus load shown on an angiogram. They review the registries, trials and meta-analyses on deferred stenting in the literature and analyse the benefits and harms of the strategy. They also propose an algorithm for applying a strategy for deferred stenting in clinical practice based on the available data.

Architecture, Religion, and the Forms of Nature in Turn-of-the-Twentieth-Century Chicago
Authors: Ellis Isaiah
Published: April 2021

The commercial architectural style that emerged in Chicago in the late nineteenth-century United States constituted a material gathering point for that century’s masculinities, religious histories, and conceptions of nature. This was especially true in the case of Louis Henri Sullivan (1856–1924), an inmuential lgure in crafting the aesthetic of this ‘Chicago School’ of architectural practice. Drawing on transcendentalist literature and recent innovations in architectural design, Sullivan outlined an ‘organic’ theory of architecture made famous in his pithy expression: form follows function. His design and theorization of free-standing structures offered gendered forms as the constitutive vocabulary of American architecture, with those very forms—not just the skyscraper but the free-standing structure writ-large—governing the relation of nature and its spirit to the masculinized landscape of urban commercial expansion. In Sullivan’s work, the gendered body became the vehicle for natural laws, both material and divine.
Influence of stress conditions on the quality of obtained sprouts – modification of their chemical composition
Authors: Zielińska-Dawidziak Magdalena
Published: April 2021

Sprouts are generally accepted as a pro-healthy food. They are consumed as a source of valuable macronutrients, antioxidants, microelements, and vitamins. Changing growth conditions of sprouts enables modification of their nutritional quality, as well as their safety. Thus, in order to achieve the most desirable composition of the produced sprouts, the conditions for their production are optimized. The aim of this review is to present methods currently used to modify the nutritional quality of plant sprouts. Most scientific works focus on stress conditions inducing the synthesis of secondary metabolites, mainly antioxidants. An increase in their content is achieved after application of physical (e.g., light illumination, temperature) or chemical factors (e.g., salinity stress, phytohormones, metal ions, etc). Though the application of these modifications on a larger scale is problematic. These problems include difficulties in predicting the effect of the stressor and an increased price of the obtained sprouts. However, since it is possible to enrich sprouts with valuable health-promoting substances, these methods are still considered very promising.

Published: April 2021

This article reports a study of the degradation of roasted sesame hulls cellulosic polysaccharides contribution to the Maillard and caramelization reaction. In the present study, cellulosic polysaccharides were extracted from sesame hulls before and after roasting at various temperatures (160, 180, 200, and 220 °C). The structural vari-ations of the cellulosic polysaccharides were elucidated by using the techniques: scanning electron microscope (SEM), high-performance anion-exchange chromatography, Fourier transform (FT-IR) spectrometer, carbon-13 nuclear magnetic resonance (CP/MAS 13C-NMR), and thermal gravimetric analysis. The pyrolysisgas chromatography-mass spectrometry (Py-GC/MS) characterized and verified the chemical composition obtained from the polysaccharide degradation during roasting. The sugar analysis results showed that galacturonic acid, xylose, and rhamnose were more easily degraded than arabinose, galactose, glucose, and mannose. The morphology of the cellulosic polysaccharides shows irregular dispersed globular fragments after roasting by SEM observation. FT-IR and CP/MAS 13C-NMR spectra indicated the crystalline structure and linkages of the cellulose did not break down in comparison to amorphous cellulose that partly degraded. Abundant acetic acid and 3-furaldehyde were among the polysaccharide degradation products identified by Py-GC/MS. These chemical compounds were likely the significant contributors to caramelization and the Maillard reaction in sesame seed roasting.

Published: April 2021

Dying (or dead) cells are increasingly recognized to impose significant biological influence within their tissues of residence—exerting paracrine effects through proteins and metabolites that are expressed or secreted during cellular demise. For example, certain molecules function as potent mitogens, promoting the repopulation of neighboring epithelial cells. And other myriad of factors—classified as damage-associated molecular patterns (DAMPs)—function as “find me” (attractant), “eat me” (engulfment), or “danger” (activation) signals for recruiting and activating effector immune cells (e.g., dendritic cells) to initiate inflammation. Since the discovery of immunogenic cell death (ICD), the current dogma posits DAMPs as immunological adjuvants for innate immune cell mobilization and activation, which ultimately leads to the antitumoral cross-priming of CD8+ T cells. However, what is currently unknown is how these immunostimulatory DAMPs are counteracted to avoid immune-overactivation. Our recent work builds on these fundamentals and introduces prostaglandin E2 (PGE2) as an ‘inhibitory’ DAMP—a new variable to the ICD equation. Prostaglandin E2 functions as an immunosuppressive counterpoise of adjuvant DAMPs; and thus, mechanistically precludes ICD. Furthermore, the long-debated immunogenicity of gemcitabine chemotherapy was revealed to be contingent on inhibitory DAMP blockade and not due to its inability to promote DAMP expression (i.e., calreticulin) as previously reported. These findings were intriguing. First, despite the presence of gemcitabine-induced hallmark DAMPs, the inhibitory DAMP (i.e., PGE2) was sufficient to hinder the ICD-induced antitumoral immune response (Fig. 1a). And second, rather than pharmacologically substantiating immunostimulatory DAMPs as conventionally approached, the mitigation of the inhibitory DAMP—tipping the immunostimulatory and inhibitory DAMP balance in favor of immunostimulatory DAMPs—was sufficient to render the cell death immunogenic and converted gemcitabine into an ICD-inducing therapy (Fig. 1b). In this microreview, we extrapolate our findings and implicate the value of inhibitory DAMP(s) in drug discovery, its use for clinical prognosis, and as target(s) for therapeutic intervention.

Shonna Trinch and Edward Snajdr decipher signage in a way that will prevent you from looking at a sign in the same manner again. Their research is built on a series of site visits, observations, and ethnographic interviews and they posit that signage plays an important role in gentrification. As they explain it, signs effect public space; well designed and interesting signs are important attributes of placemaking, often part of a strategy for cities to reclaim their appeal.

The growing ageing population in China poses a huge demand for rehabilitation care, which can be satisfied by the latest robot technology. Focusing on the motion system of a six degrees-of-freedom (DOF) robot, this paper explores the relationship between the force, torque, velocity and the postures of the end effector and joint. Drawing on robot control theories, the existing manipulator force/position hybrid controllers were reviewed, and a force/position hybrid controller was designed for path planning of rehabilitation robot. Then, the robot was modelled on the Robot Operating System (ROS), using the Unified Robot Description Format (URDF) file and the MoveIt! Setup Assistant. Finally, our controller was tested in the ROS virtual simulation environment. The results show that our controller can facilitate and optimize the design of the path of rehabilitation robot.
Exploring Analytical Models for Performability Evaluation of Virtualized Servers using Dynamic Resource
Authors: Kirsal Yonal
Published: April 2021

Virtualization of resources is a widely accepted technique to optimize resources in recent technologies. Virtualization allows users to execute their services on the same physical machine, keeping these services isolated from each other. This paper proposes the analytical models for performability evaluation of virtualized servers with dynamic resource utilization. The performance and avalability models are considered separately due to the behaviour of the proposed system. The well-known Markov Reward Model (MRM) is used for the solution of the analytical model considered together with an exact spectral expansion and product form solution. The dynamic resource utilization is employed to enhance the QoS of the proposed model which is another major issue in the performance characterization of virtulazilation. In this paper, the performability output parameters, such as mean queue length, mean response time and blocking probability are computed and presented for the proposed model. In addition, the performability results obtained from the analytical models are validated by the simulation (DES) results to show the accuracy and effectiveness of the proposed work. The results indicate the proposed modelling results show good agreement with DES and understand the factors are very important to improve the QoS.

Published: April 2021

In recent years, air pollution has seriously affected people’s production and life, so the air prediction has become a research hotspot in recent years. When analyzing air data, it is found that this type of data has not only temporal correlation, but also spatial correlation. For these temporal and spatial characteristics, this paper studies deep spatio-temporal learning method to global prediction. The purpose is to learn the evolution rule behind the spatio-temporal sequence, and give an estimation for future state. To be specific, we propose two novel forecasting models based on video processing technology: Spatio-temporal Orthogonal Cube model (STOR-cube) and Spatio-temporal Dynamic Advection model (ST-DA), which effectively capture the spatio-temporal correlation and accurately predict the long-term air quality. STOR-cube contains three branches, i.e., a spatial branch for capturing moving objects, a temporal branch for processing motion, and an output branch for coupling the first two mutually orthogonal branches to generate a prediction frame. ST-DA constructs a spatio-temporal reasoning network to learn the characteristics of the spatio-temporal domain, and its impact on the future is explicitly modeled by pixel motion. Experiments results on the real-world datasets demonstrate our proposed approach significantly outperforms the state-of-the-art ones. Moreover, our model can be extended to other spatio-temporal data prediction tasks.

Published: April 2021

Home helper robots have become more acceptable due to their excellent image recognition ability. However, some common household tools remain challenging to recognize, classify, and use by robots. We designed a detection method for the functional components of common household tools based on the mask regional convolutional neural network (Mask-R-CNN). This method is a multitask branching target detection algorithm that includes tool classification, target box regression, and semantic segmentation. It provides accurate recognition of the functional components of tools. The method is compared with existing algorithms on the dataset UMD Part Affordance dataset and exhibits effective instance segmentation and key point detection, with higher accuracy and robustness than two traditional algorithms. The proposed method helps the robot understand and use household tools better than traditional object detection algorithms.

Published: April 2021

The resource optimization of ultra-dense networks (UDNs) is critical to meet the huge demand of users for wireless data traffic. But the mainstream optimization algorithms have many problems, such as the poor optimization effect, and high computing load. This paper puts forward a wireless resource allocation algorithm based on deep reinforcement learning (DRL), which aims to maximize the total throughput of the entire network and transform the resource allocation problem into a deep Q-learning process. To effectively allocate resources in UDNs, the DRL algorithm was introduced to improve the allocation efficiency of wireless resources; the authors adopted the resource allocation strategy of the deep Q-network (DQN), and employed empirical repetition and target network to overcome the instability and divergence of the results caused by the previous network state, and to solve the overestimation of the Q value. Simulation results show that the proposed algorithm can maximize the total throughput of the network, while making the network more energy-efficient and stable. Thus, it is very meaningful to introduce the DRL to the research of UDN resource allocation.

Published: April 2021

It is thought that the COVID-19 outbreak has significantly fuelled racism and discrimination, especially towards Asian individuals[10]. In order to test this hypothesis, in this paper, we build upon existing work in order to classify racist tweets before and after COVID-19 was declared a global pandemic. To overcome the difficult linguistic and unbalanced nature of the classification task, we combine an ensemble of machine learning techniques such as a Linear Support Vector Classifiers, Logistic Regression models, and Deep Neural Networks. We fill the gap in existing literature by (1) using a combined Machine Learning approach to understand the effect of COVID-19 on Twitter users’ attitudes and by (2) improving on the performance of automatic racism detectors. Here we show that there has not been a sharp increase in racism towards Asian people on Twitter and that users that posted racist Tweets before the pandemic are prone to post an approximately equal amount during the outbreak. Previous research on racism and other virus outbreaks suggests that racism towards communities associated with the region of the origin of the virus is not exclusively attributed to the outbreak but rather it is a continued symptom of deep-rooted biases towards minorities[13]. Our research supports these previous findings. We conclude that the COVID-19 outbreak is an additional outlet to discriminate against Asian people, instead of it being the main cause.

Background: Colorectal cancer is the second leading cause of mortality and the most prevalent cancer worldwide. Most patients, who come with late-stage, have ineffective treatments and some side effects in chemotherapy. Aaptos suberitoides has potential anti-cancer effects due to its bioactive compounds such as aptamine. This study aimed to evaluate the migration inhibition effect of Aaptos suberitoides fraction in HCT-116 cell line.Methods: This study was an experimental study. Aaptos suberitoides specimen was taken in Tinjil Island and fractionated with ethyl acetate. HCT-116 cell line was added with Aaptos suberitoides fraction and cellular migration activity was observed in 48 hours of which the scratch assay was performed. The gap closure area was determined with ImageJ software.Results: The data showed that a low concentration of Aaptos suberitoides fraction inhibited migration activity in HCT-116 cell line as follow; 1 and 5 mg/L Aaptos suberitoides fraction inhibit 3-4 % cancer cell migration in 24 hours, and 10-11% inhibition in 48 hours, respectively. However, 10 mg/L fraction concentration only inhibited 7-14% of the migration effect.Conclusion: Aaptos suberitoides fraction suggests insignificant migration inhibition in colorectal cancer cells and only inhibits less than 15 % HCT-116 cell line.
