Einstein's Elevator: World Lines, Michelson-Morley Experiment and Relativistic Paradox
Authors: Rouaud Mathieu
Published: December 2021

We all have in mind Einstein's famous thought experiment in the elevator where we observe the free fall of a body, and then the trajectory of a light ray. Simply here, in addition to the qualitative aspect, we carry out the exact calculation, and for the first time the worldlines equations are given. We consider a uniformly accelerated reference frame in rectilinear translation, and we show that the trajectories of the particles are semi-ellipses with the center on the event horizon. The frame of reference is non-inertial, the space-time is flat, and the computations are performed within the framework of special relativity. Some experimental consequences are discussed, especially the experiment with the accelerated Michelson-Morley interferometer is solved, and we described an experiment where a new relativistic paradox appears --- a particle of matter seems to go faster than light. The differences, compared to the classical case, are important at large scale and close to the horizon, but they are small in the lift where the interest is above all theoretical. The concepts of metric, coordinated velocity and horizon are discussed, and the analogy with the black hole is made.

Authors: Safwat Nour El-Din , Newagy Fatma , Hafez Ismail
Published: December 2021

In this paper, a new relay system that uses the UAV as a relay station between the tethered UAV and ground user (TU2U2G) is proposed. The TU2U2G system replaces the base station (BS) in the cellular system with a tethered UAV (TUAV). The TUAV is a UAV that receives power over a cable from a ground control station. It has advantages of high and variable altitude up to (100m) compared to BS. In addition, it overcomes the UAV drawback of the batteries' limited capacity. After that, a 3D placement Algorithm of the UAV as a relay station in the TU2U2G system is proposed. It is presented to maximize the coverage by jointly optimizing the transmitting power and relaying distance. The TU2U2G system shows better results than the traditional cellular system in terms of optimum UAV height, maximum coverage radius, and maximum distance between BS and UAV.

Published: December 2021

Scientists and astronomers have attached Scientists and astronomers have attached great importance to the task of discovering new exoplanets, even more so if they are in the habitable zone. To date, more than 4300 exoplanets have been confirmed by NASA, using various discovery techniques, including planetary transits, in addition to the use of various databases provided by space and ground-based telescopes. This article proposes the development of a deep learning system for detecting planetary transits in Kepler Telescope lightcurves. The approach is based on related work from the literature and enhanced to validation with real lightcurves. A CNN classification model is trained from a mixture of real and synthetic data, and validated only with real data and different from those used in the training stage. The best ratio of synthetic data is determined by the perform of an optimisation technique and a sensitivity analysis. The precision, accuracy and true positive rate of the best model obtained are determined and compared with other similar works. The results demonstrate that the use of synthetic data on the training stage can improve the transit detection performance on real light curves.

Published: December 2021

Deep learning techniques are increasingly being recognized as effective image classifiers. Aside from their successful performance in past studies, the accuracies have varied in complex environments in comparison with the popularly applied machine learning classifiers. This study seeks to explore the feasibility for using a U-Net deep learning architecture to classify bi-temporal high resolution county scale aerial images to determine the spatial extent and changes of land cover classes that directly or indirectly impact tidal marsh. The image set used in the analysis is a collection of a 1-m resolution collection of National Agriculture Imagery Program (NAIP) tiles from 2009 and 2019 covering Beaufort County, South Carolina. The U-net CNN classification results were compared with two machine learning classifiers, the Random Trees (RT) and the Support Vector Machine (SVM). The results revealed a significant accuracy advantage in using the U-Net classifier (92.4%) as opposed to the SVM (81.6%) and RT (75.7%) classifiers for overall accuracy. From the perspective of a GIS analyst or coastal manager, the U-Net classifier is now an easily accessible nad powerful tool for mapping large areas. Change detection analysis indicated little areal change on marsh extent, though increased land development throughout the county has the potential to negatively impact the health of the marshes. Future work should explore applying the constructed U-Net classifier to coastal environments in large geographic areas, while also implementing other data sources (e.g., LIDAR, multispectral data) to enhance classification accuracy.

Published: December 2021

The aim of the work is to develop a technology for the restoration of damaged sections of sewer collectors using clinker bricks. A significant part of such collectors in the Ukraine has completely exhausted their depreciation resource. For their construction, concrete and reinforced concrete were used, which are subject to destruction as a result of the influence of many factors and, above all, microbiological corrosion. Therefore, the selection of the optimal repair technology using corrosion-resistant clinker brick is relevant. The paper considers the problems of repair and reconstruction of worn-out collectors. Technical and technological solutions of an open method for their recovery using pneumatic formwork and corrosionresistant clinker brick are presented. The design of the collector lining structure has been carried out using the finite element method. To justify the feasibility of using the proposed technology, two options for restoring a worn-out collector have been considered: the “pipe-in-pipe” method and method developed by the authors using clinker bricks. The second option in terms of the cost of materials is almost four times more economical and more expedient than the first one (where polymer materials are used). The advantage of restoring circular sewer collectors by means of laying clinker bricks lies in the durability and resistance of this material (taking into account the anticorrosive composition of concrete) to the aggressive effects of the sewer environment. It should be noted that the application of the developed restoration technology is the most appropriate in conditions of sparse building or outside the city due to the significant volume of earthworks.

Published: December 2021

Results of a study of an actual scientific and technical problem of determining the road safety level on road sections are presented in the paper. The aim of the study is to develop an express method for assessing road safety based on improving the method of the final accident rate by reducing the partial accident rate with the required accuracy of determining the safety level on public roads. The formalization of the relationship between the parameters of road traffic conditions has been carried out to study the level of safety on highways. Latent factors of the parameters of traffic conditions have been obtained on the basis of reduction of their aggregate by the method of principal components, taking into account the relationship of partial accident rates. This condition has allowed to develop analytical models for determining road safety for implementation in the practice of conducting a road safety audit. A method for identifying hazardous areas on highways has been proposed in the paper. It includes 11 parameters of road conditions out of 18 partial accident rates proposed in the prototype and regulatory documents of Ukraine. The adequacy of the model is determined by deviation values of the obtained data according to the prototype model from the values of the relative accident rate, which were 3.22 and 18.61, respectively. The proposed model reduces the deviation value by six times and affects the accuracy of determining the safety level. Experimental studies have been conducted on 79 km of highways (on 385 sectors with constant values of traffic conditions parameters). The results of a comparative analysis of the safety level for the prototype model and the developed model have been identical and shown a decrease in time and labor costs by 1.6 times without loss of accuracy. Thus, the developed methodology is recommended to be applied for determining the potential danger of road sections during an express analysis of the road safety or when conducting a safety audit at various stages of the road life cycle.

This research departs from the community's problem of taking rice bran as an additional wage for mobile rice milling services. The purpose of this study focuses on the phenomenon of wages (Ijarah) for mobile rice mill services, which is then analyzed based on the perspective of Islamic law. The type of research used is field research using qualitative research methods and data collection techniques through interviews. In this study, it was found that the wages of the mobile rice milling contract in Gegeran Sukorejo Ponorogo Village were not entirely following Islamic law because the determination of wages was only carried out by one party and taking additional wages in the form of rice bran without any openness and willingness from the farmers, thus harming one of the farmers. Parties, namely farmers or consumers. Regarding the Ijarah agreement, the mobile rice mill service in Gegeran Sukorejo Village, Ponorogo, is not entirely following Islamic law because the transaction does not fulfil the principles in the contract, especially the principle of ibahah, the principle of trust (honesty), fairness and balance of achievements. Although in the transaction between the two, there is a valid qabul ijāb.

Published: December 2021

Monitoring product temperature during lyophilization is of critical importance, especially during the process development stage, as the final product may be jeopardized if its process temperature exceeds a threshold value. While conventional thermocouples can track product temperature, they are invasive and can significantly alter the freezing and drying behavior. In this work, a new methodology for non-invasive product temperature monitoring and drying behavior during the entire lyophilization process is proposed and experimentally validated. The method is based on a new flexible wireless multi-point temperature sensing probe that is attached to the outside of the vial. Combining the wirelessly-collected data with advanced multi-physics simulations allows the accurate extraction of the product temperature non-invasively.

Authors: Sauchelli Sarah , Pickles Tim , Voinescu Alexandra , Choi Heungjae , Sherlock Ben , Zhang Jingjing , Colyer Steffi , Grant Sabrina , Sundari Sethu , Lasseter Gemma
Published: December 2021

Background
Innovation in healthcare technologies can result in more convenient and effective treatment that is less costly, but a persistent challenge to widespread adoption in health and social care is end user acceptability. The purpose of this study was to capture UK public opinions and attitudes to novel healthcare technologies (NHTs), and to better understand the factors that contribute to acceptance and future use.
Methods
An online survey was distributed to the UK public between April and May 2020. Respondents received brief information about four novel healthcare technologies (NHTs) in development: a laser-based tool for early diagnosis of osteoarthritis, a virtual reality tool to support diabetes self-management, a non-invasive continuous glucose monitor using microwave signals, a mobile app for patient reported monitoring of rheumatoid arthritis. They were queried on their general familiarity and attitudes to technology, and their willingness to accept each NHT in their future care. Responses were analysed using summary statistics and content analysis.
Results
Knowledge about NHTs was diverse, with respondents being more aware about the health applications of mobile apps (66%), followed by laser-based technology (63.8%), microwave signalling (28%), and virtual reality (18.3%). Increasing age and the presence of a self-reported medical condition favoured acceptability for some NHTs, whereas self-reported understanding of how the NHT works resulted in elevated acceptance scores across all NHTs presented. Common contributors to hesitancy were safety and risks from use. Respondents wanted more information and evidence to help inform their decisions, ideally provided verbally by a general practitioner or health professional. Other concerns, such as privacy, were NHT-specific but equally important in decision-making.
Conclusions
Early insight into the knowledge and preconceptions of the public about NHTs in development can assist their design and prospectively mitigate obstacles to acceptance and adoption.

Published: December 2021

The effect of (1-x)(Pb0.97La0.02)(Zr0.675Sn0.285Ti0.04)O3-xAl2O3, with x=0~0.04, 0.08, 0.10 composite ceramic samples was studied. In this experiment, the PLZST powder was pre-fired to obtain the perovskite structure, and then combined with α-Al2O3 to increase the BDS of the ceramic. The test results show that the composite thick film samples are all perovskite orthorhombic phases, and Al2O3 is mainly filled in the grain gaps with a flaky structure. A proper content of composite Al2O3 can increase the density of ceramics. With x=0.02, the maximum value of BDS is 25.27 kV/mm, which is 60% higher than pure PLZST material, and the releasable energy storage density also reaches a maximum of 2.95 J/cm³. After the composite amount exceeds 0.03, the saturation polarization intensity decreases significantly. The energy storage efficiency of each sample is generally not high, all of which are less than 65%.

Published: December 2021

Circulating tumor cell (CTC) clusters possess a much higher capability to seed metastasis than single CTCs. However, the mechanism underlying this phenomenon is still elusive and no reports have investigated the role of posttranscriptional RNA regulation in CTC clusters. Here, we compared alternative splicing (AS) and alternative polyadenylation (APA) profiles between single CTCs and CTC clusters. 994 and 836 AS events were identified in single CTCs and CTC clusters, separately. About ~20% of AS events exhibited alterations between both cell types. The differential splicing of SRSF6 was a core event that caused AS profiles’ disturbance and made CTC clusters more dangerous. Concerning APA, we identified global 3’ UTRs lengthening in CTC clusters compared with single CTCs. This change was mainly regulated by 14 core APA factors, especially PPP1CA. The altered APA profiles boosted the cell cycle of CTC clusters and reflected that CTC clusters endured less oxidative stress. Our study investigated the posttranscriptional regulation mechanisms in CTC clusters, found that the perturbation of AS and APA contributed to the superiority of CTC clusters compared with single CTCs, and laid the foundation for developing antisense oligonucleotides that inhibit metastasis by reducing CTC clusters.

Authors: Kristensen Charlotte Burup , Myhr Katrine Aagaard , Grund Frederik Fasth , Vejlstrup Niels , Hassager Christian , Mattu Raj , Mogelvang Rasmus
Published: December 2021

Purpose
Increased left ventricular mass (LVM) is a strong independent predictor for adverse cardiovascular events, but conventional echocardiographic methods used to assess and monitor individuals are limited by poor reproducibility and accuracy. We aimed to develop an echocardiographic method for LVM-quantification that is simple, reproducible and accurate.
Methods
The novel method adds the mean wall thickness to the left ventricular end-diastolic volume acquired using the biplane model of discs. The mean wall thickness is acquired from the parasternal short axis view. Cardiac assessment was performed using echocardiography followed immediately by cardiac magnetic resonance in 85 subjects with different left ventricular geometries, ranging from patients with various cardiac disorders (n=41) to individuals without known cardiac disorders (n=44). We compared the novel two-dimensional (2D) method to various conventional one-dimensional (1D) and 2D methods as well as three-dimensional (3D) echocardiography.
Results
The novel method had better reproducibility in intra-examiner (coefficients of variation (CV) 9% vs. 11-14%) and inter-examiner analysis (CV 9% vs. 10-20%) than the other methods. Accuracy of the novel method was similar to 3D (mean difference±95% limits of agreement, CV): Novel: 2±50g,15% vs. 3D: 2±51g, 16%; and better than the 1D-method by Devereux (7±76g, 23%).
Conclusion
The novel 2D-based method for LVM-quantification had better reproducibility than the other echocardiographic methods. Accuracy was similar to 3D and better than conventional methods. As endocardial tracings using the biplane model forms part of the standard echocardiographic protocol, the novel method can easily be integrated into any echocardiographic software, without substantially increasing analysis time.

Published: December 2021

The ongoing COVID-19 pandemic let to efforts to develop and deploy digital contact tracing systems to expedite contact tracing and risk notification. Unfortunately, the success of these systems has been limited, partly owing to poor interoperability with manual contact tracing, low adoption rates, and a societally sensitive trade-off between utility and privacy. In this work, we introduce a new privacy-preserving and inclusive system for epidemic risk assessment and notification that aims to address these limitations. Rather than capturing pairwise encounters between user devices as done by existing systems, our system captures encounters between user devices and beacons placed in strategic locations where infection clusters may originate. Epidemiological simulations using an agent-based model demonstrate that, by utilizing location and environmental information and interoperating with manual contact tracing, our system can increase the accuracy of contact tracing actions and may help reduce epidemic spread already at low adoption.

Biblioteconomia social, crítica e progressista
Authors: Tanus Gabrielle Francinne de Souza Carvalho , Silva Daniela Cândido da
Published: December 2021

A Biblioteconomia é um campo científico que tem apresentado nas últimas décadas a discussão mais forte sobre seu caráter social e a importância de se afastar de uma base conservadora. Assim, novos termos qualificadores desta Biblioteconomia podem ser encontrados como, por exemplo, Biblioteconomia Social, Progressista e Crítica. Essa Biblioteconomia alternativa e sua produção consiste no foco desta pesquisa cujo objetivo geral é mapear a produção científica indexada em distintas bases de dados. O procedimento metodológico selecionado foi a bibliometria, de cunho quantitativo, que visa, nesse primeiro momento, identificar a ocorrência dos termos “Biblioteconomia Social”, “Biblioteconomia Progressista” e “Biblioteconomia Crítica”, assim como os termos correspondentes em inglês “Social Librarianship”, “Progressive Librarianship” e “Critical Librarianship”. Assim, foram selecionadas intencionalmente duas bases de dados, uma nacional e outra internacional, para a coleta de dados, a saber: Base de Dados em Ciência da Informação (BRAPCI) e Library and Information Science Abstracts (LISA). A pesquisa com os termos nas referidas bases ocorreu em janeiro de 2019, por conseguinte, os dados coletados foram tabulados e apresentados neste artigo. Foi possível perceber que o uso dos termos ainda é pouco presente na produção biblioteconômica, haja vista que passaram a ser utilizados a partir da década de 2000. No Brasil, o “divisor de águas” foi o Congresso Brasileiro de Biblioteconomia, Documentação e Ciência da Informação (CBBD), de 2017, tendo em um dos eixos temáticos a presença do termo “Biblioteconomia social”.
Biomacromolecule-Functionalized Nanoparticle-Based Conjugates for Potentiation
of Anticancer Therapy
Authors: Shah Priyank , Shende Pravin
Published: December 2021

:

Cancer is a rapidly growing life-threatening disease that affected 18.1 million people
worldwide in 2018. Various conventional techniques like surgery, radiation, and chemotherapy are
considered as a mainstream treatment for patients but show some limitations like cytotoxicity due
to off-targeted action, poor intra-tumor localization, development of multi-drug resistance by tumor
cells, physical and psychological stresses, etc. Such limitations have motivated the scientists
to work towards more patient-centric and precision therapy using advanced drug delivery systems
like liposomes, nanoparticles, nanoconjugates, etc. However, these carriers also face limitations
like poor biocompatibility, lesser payload capacity, leakage of encapsulated drug, and short-term
stability. So, this review article explores the profound insights for the development of biomacromolecule-
functionalized nanoconjugates to potentiate the anticancer activity of therapeutic agents
for various cancers like lung, colorectal, ovarian, breast and liver cancer. Researchers have shown
interest in biofunctionalized nanoconjugates because of advantages like biocompatibility, site-specificity
with better localization, higher entrapment with long-term stability and lesser off-target toxicity.
The progressive trend of biomacromolecule nanoconjugates will encourage further research for
the development of effective transport of drugs, nutraceuticals and phytoconstituents for on-site effect
at cancer microenvironment and tumor cells with higher safety profile.

Published: December 2021

:

Shoulder pain is an extremely common condition. The painful shoulder may be the result
of a wide spectrum of underlying pathological conditions, including calcific tendinopathy of
the rotator cuff, subacromial-subdeltoid bursitis, acromioclavicular or glenohumeral arthritis,
tenosynovitis of the long biceps tendon, rotator cuff lesions, and many other less common conditions.
Ultrasound imaging is an effective tool for the diagnosis and also for the image guidance of
treatment of the majority of these conditions. Several ultrasound-guided procedures are effective
for pain relief, such as percutaneous irrigation, intra-bursal or intra-articular drugs injection, fluid
aspiration, neural block. This review article aims to summarize and discuss the most common treatment
possibilities with ultrasound guidance for the painful shoulder.

Published: December 2021

Background:

Attention Deficit Hyperactivity Disorder (ADHD) is the most common neuropsychological developmental disorder in children. ADHD is characterized by inattention, overactivity, and impulsivity. However, the attention skill is not clearly studied in children with ADHD in Indonesia.

Objective:

The aim of the present study was to investigate the differences in attention skill between children with ADHD and typically developing children (TD), and identify the differences between ADHD subtypes at primary schools in Bandung city Indonesia in terms of the parameter of attention.

Methods:

This study used the quantitative method. The population of this study was children with ADHD and typically developing (TD) school-age children. The data sampling technique was purposive sampling, consisting of 30 children as a group of ADHD children and 30 children as a group of TD children. The instrument to collect data was Wechsler Intelligence Scale for Children (WISC), Indonesian ADHD Rating Scale (IARS), and The D2 test of attention. The analysis method used t-test and SPSS V.24 for Windows.

Results:

This study showed significant differences in attention skill performance between children with ADHD and TD children in the variables including the total number of tasks completed, omission, commission, error rate, total amount minus errors or selective attention skill, fluctuation rate and concentration performance. There have been observed significant differences between ADHD subtypes in terms of total number, omission, commission, error rate, total amount minus errors or selective attention skill, and concentration performance.

Conclusion:

Children with ADHD were found to have lower results than typically developing children in terms of attention skill, inhibiting control, and ability in performance accuracy.

:

The incidence of carbapenem-resistant gram-negative (CRGNB) bacterial infections has
increased globally. The wide diversity of strains, multiplicity of infections, and rapid development
and spread of resistance are a matter of great concern both in community and hospital settings.
Cefiderocol is a novel injectable siderophore containing cephalosporin with potent microbicidal activity
against most carbapenem-resistant Enterobacteriaceae (CRE). It has recently been approved
by USFDA for the treatment of complicated urinary tract infections (cUTI) caused by susceptible
gram-negative microorganisms.
This review focuses on the salient pharmacological profile of the drug and the clinical studies that
were undertaken.
Cefiderocol is first in class injectable siderophore cephalosporin showing potency against carbapenem-
resistant Enterobacteriaceae. It has recently been approved by US FDA for the treatment of
adult patients with complicated urinary tract infections (cUTI) caused by susceptible Gram-negative
microorganisms, where there are limited or no alternative treatment options.

Authors: Niu Wangqiang , Huang Jiaying , Wang Xiaotong
Published: December 2021

Background:

In wind power generation, the power curve can reflect the overall power
generation performance of a wind turbine. How to make the power curve have high precision and
be easy to interpret is a hot research topic.

Objective:

Because the current power curve modeling method is not comprehensive in feature selection,
the simplified model and state curve of a wind turbine are introduced to avoid feature selection
and make the model interpret easily.

Methods:

A power modeling method based on different working conditions is proposed. The
wind turbine system is simplified into three physical models of blades, mechanical transmission
and generator, and the energy transfer is expressed by mathematical expressions. The operation
process of the wind turbine is divided into three phases: Constant Power (CP), Constant Speed
(CS), and Maximum Power Point Tracking (MPPT), and the power expression of each phase is
given after the analysis of state curves.

Results:

The effectiveness of the proposed method is verified by the Supervisory Control and
Data Acquisition (SCADA) data of a 2MW wind turbine. The experimental results show that the
Mean Absolute Percentage Error (MAPE) index of the proposed power modeling method based
on state curve analysis is 11.56%, which indicates that the power prediction result of this method
is better than that of the sixth-order polynomial regression method, whose MAPE is 13.88%.

Conclusion:

The results show that the proposed method is feasible with high transparency and is
interpreted easily.

Consumers are holders of important information in the management and planning of business development. The purpose of the study is to analyze consumer attitudes towards various processed milkfish and analyze the performance of product attributes of various processed milkfish in Glagah District, Lamongan Regency. The data analysis method used is descriptive analysis, Fishbein attitude model and Importance Performance Analysis (IPA). The results showed that the respondent's assessment of the processed otak-otak and smoked milkfish stated a neutral attitude, and the respondent's assessment of the shredded milkfish and crackers stated a positive attitude. The performance attributes of various processed milkfish included in quadrant I measure the processed otak-otak and the processed abon. Attributes included in quadrant II are taste and price for processed otak-otak, smoked, and crackers, while shredded milkfish only have tasted attributes. Attributes included in quadrant III are product packaging and ease of access for all kinds of milkfish preparations. Attributes included in quadrant IV are the size of the product for shredded and milkfish crackers. It does recommend that producers of otak-otak and smoked milkfish improve their products to get a positive attitude from customers.

The purpose of this study is to find out how parents play in training the speech of deaf children. The research method used is qualitative with library research, namely a series of studies related to library data collection methods, or research objects whose research objects are excavated through various library information (books, encyclopedias, scientific journals, newspapers, magazines, and documents). The results showed that parents have tried to train their children by getting used to talking continuously during learning from home using props and motivating the child to learn. Parents and teachers work together and consult on how to practice speech. The development of sound and rhythm perception communication is a program that is carried out to train the ability of deaf children. But at the time of the covid-19 pandemic parents became special companions as well as teachers while at home to train their children to speak the language daily in addition to being helped through listening aids guided by their teachers.
Community-based Approach to Empower People with Disabilities

Published: December 2021

This article seeks to understand the empowerment issues of persons with disabilities. Various development programs have been implemented to reduce stigma, prejudice and stereotypes that impede persons with disabilities from having greater access to education, employment or the labor markets and public services. However, research findings showed that many interventions and strategies to address disability issues focus more on individual or medical models. As a consequence, public stigma and social exclusion of persons with disabilities continue to occur, preventing them from participating in various activities in the society including in the tourism sector. The purpose of this study is to identify social reasons that lead to exclusion and lack of empowerment, as well as to establish programs at the community level to increase the engagements of persons with disabilities in tourist attractions and tourist destinations in Malang. The result of the study shows that the insufficient skills and knowledge of the community members of Desa Kalisanga (nicknamed Kampung Cempluk) in communicating and interacting with persons with disabilities cause the lack of awareness in regard to disability issues. Using macro perspective, this study exhibits community-based approach which requires participation of community members in the planning and organizing an inclusive arts and music festival in Kampung Cempluk. The community was successfully provided various accessibility facilities needed by persons with disabilities to participate, both attending and performing at the festival. This study shows that community-based approach could be employed as a model or strategy to empower persons with disabilities by providing them with equal opportunities to participate in tourist attractions or other activities in the society and wider access to tourist destinations and other public facilities.
