An analysis of scatter characteristics in x-ray CT spectral correction
Authors: Zhang Tao , Chen Zhiqiang , Zhou Hao , Bennett N Robert , Wang Adam S , Gao Hewei 
Published: March 2021

Abstract
X-ray scatter remains a major physics challenge in volumetric computed tomography (CT), whose physical and statistical behaviors have been commonly leveraged in order to eliminate its impact on CT image quality. In this work, we conduct an in-depth derivation of how the scatter distribution and scatter to primary ratio (SPR) will change during the spectral correction, leading to an interesting finding on the property of scatter. Such a characterization of scatter’s behavior provides an analytic approach of compensating for the SPR as well as approximating the change of scatter distribution after spectral correction, even though both of them might be significantly distorted as the linearization mapping function in spectral correction could vary a lot from one detector pixel to another. We conduct an evaluation of SPR compensations (SPRCs) on a Catphan phantom and an anthropomorphic chest phantom to validate the characteristics of scatter. In addition, this scatter property is also directly adopted into CT imaging using a spectral modulator with flying focal spot technology (SMFFS) as an example to demonstrate its potential in practical applications. For cone-beam CT (CBCT) scans at both 80 and 120 kVp, CT images with accurate CT numbers can be achieved after spectral correction followed by the appropriate SPRC based on our presented scatter property. In the case of the SMFFS based CBCT scan of the Catphan phantom at 120 kVp, after a scatter correction using an analytic algorithm derived from the scatter property, CT image quality was significantly improved, with the averaged root mean square error reduced from 297.9 to 6.5 Hounsfield units.

Authors: Ma Wen-Xiu 
Published: March 2021

Abstract
A linear superposition is studied for Wronskian rational solutions to the KdV equation, which include rogue wave solutions. It is proved that it is equivalent to a polynomial identity that an arbitrary linear combination of two Wronskian polynomial solutions with a difference two between the Wronskian orders is again a solution to the bilinear KdV equation. It is also conjectured that there is no other rational solutions among general linear superpositions of Wronskian rational solutions.

Abstract
We have developed a “Self Sanitizing Voice Controlled Intelligent Wheelchair.” The wheelchair will be totally voice controlled. There will be sanitizing system for both the wheelchair and the surrounding area. In Covid-19situation, maintaining social distance is very important. Keep this in mind we will add the alert system in the wheelchair. When any person will come very close to the wheelchair it will announce a voice alert. Also this wheelchair will climb the stair without anyone’s help. This wheelchair will be developed for the disabled person as well as for the Corona patient. The assistant of the disabled person or the disabled person can be Corona affected. As the wheelchair is voice controlled, it will not need someone to push the wheelchair. It will also helpful to carry the Corona patient, where the nurse or assistant can move the wheelchair by giving voice command from a safe distance. The wheelchair will have voice controlled sanitizing system where it will be able to sanitize itself and its surrounding area. After carrying the Corona patient this wheelchair can be sanitized without going near to it. Also this wheelchair will help to sanitize the patient’s room. So, before entering the patient’s room, by giving voice command the room can be sanitized.

Published: March 2021

Abstract
In this crisis of deadly worldwide pandemic of COVID – 19, thousands of people are getting admitted in the hospitals, with the hope of getting cured. In this point of time, doctors, nurses, and the other medical staff have a lot to pressure and stress to deal with such a large number of patients. Once admitted, family members of the patients don’t get regular updates about the patient. After considering all these problems, we have proposed an idea entitled, “WeCare”, which can suitably be a solution to mitigate such problems. This will be basically, a tracker worn by a patient once admitted in the hospital. This tracker has sensors to sense various vital body parameters such as body temperature, heart rate, pulse rate and most importantly, the oxygen level in the body of the patient. The entire information is stored in the database of the hospital. Trained machines will be there to give an alert when the condition of the patient deteriorates, and immediately help will be arranged. Adequate provisions and arrangements are also made which will help the family members of the patients to keep a track of the health of the patient through a mobile app.

Abstract
People of our country are searching for all kind of protection against the virus which has been spread in all countries, according to surveys it is known that coronavirus keep active on the metallic grounds but on the other hand it can remain on shoe for three to five days. As plastic, leather, and rubber are the good transporter of viruses so daily requirements made by these materials are needed to be sanitized. If a person goes to an infected place or sneezes or speaks in front of another person can be infected easily by the globules spread over the shoes. Also, as our shoes come in contact with most of the dirt and germs, it is another reason for growing corona along with another virus. For this which virus and bacteria stay stick with the sole of the shoes can be carried to home. So, to fight against this situation, this paper proposed a smart IoT based Shoe Sanitizing System. Our proposed system will detect and remove the bacteria or virus by liquid spraying sanitizer along with the light of UV and at last, the shoes are dried with the air of DC. We can monitor and control the system over the Wi-Fi or internet by the implementation of the Node MCU and 4G GSM module. We have constructed this system to be carried out on the entry gates and doors. Through this device, a passer-by can avoid destroying the pandemic and also lower cost.

Abstract
At the end of 2019, a novel Corona Virus surfaced as a pathogen and eventually resulted in a pandemic situation. The infection rate unleashed havoc worldwide firstly affecting European nations then the US. So, in this paper we proposed a software application which intakes user data to calculate the threat based on the merits of reconducted survey which prompts the user to check if they are undergoing any of the medically proven symptoms and sends it to the local municipal clinic. This in turn will minimize the need for medical workers to visit door to door constantly at risk of getting infected. This software is equipped with features like GPS tracking, threat level predictor, contamination graph it also determines medicinal urgency etc. Basically, our system is supposed to assist the day to day workers and visit places in scenarios of maximum urgency. This proposed system is used to prevent allowing likely symptomatic as well as asymptomatic users to enter in the hotspot regions’ public places such as malls and markets. The application will generate a unique QR code for respective users which will depict their merit based on mandatory survey that whether that person is affected or not. The QR code can be used in order enter the public area places where scanners are placed.

Published: March 2021

Abstract
In this paper, we are planning to build an application through which victims of Covid-19 can put their data. Once an effective data set is built, the application is capable to predict a COVID-19 zone based on these data by using a regression model. The parameters of the data set will be:
1. How many times a person visited outside.
2. City of the person, who visited abroad recently if yes then which country (take the ratio of victims to their population density as a parameter), if no then we will put a zero.
3. The cases in their home town by simply accessing their location (take the ratio of victims to the population density of that area).
4. Once data set is built, then train a regression model to predict the chances of a person being a victim of Covid - 19 and once that information is available we can simply observe in which area the no of suspected no of people is greater through which we can tell the chance of an area being affected by this situation.
5. Although parameters of the data set are limited now but we are planning to add more so that more accurate models can be built.

Published: March 2021

Abstract
During this Covid - 19 pandemic situation, encryption of medical images takes a major role in medical information systems as well as in telemedicine. However according to government rule, it is essential to hide the information of the patients. Recent development in computer network enhances a lot of facilities in communication area. Unfortunately, hackers are misusing this facility and always try to attack on the transmitted information in insecure network. For secure transmission of medical images, it is essential to encrypt the information before transmitting. In this communication, we are going to present a novel approach of medical image encryption using cyclic coding. We have proved that it is quite difficult to decrypt the original information from encoded data in one common mode of attacking-chosen ciphertext attack. Moreover, we have proved the effectiveness of the encryption using correlation coefficients. Our proposed scheme is suitable for efficient encoding of multiple medical images.

Published: March 2021

Abstract
It endeavours to postulate a smart, economical power supply system for pacemakers based on the principle of power harnessing using piezoelectric effect, on the contrary to the existing battery powered system, resulting an enormous reduction in pacemaker cost. The proposed system will use heart vibrations to generate power from piezoelectric transducer and provide a steady DC output to the pacemaker system, reducing or omitting the need of pacemaker replacement. The proffered system also has a scope of providing a warning by pre-detecting the possible threat of future heart-disease. The general objective of the project is to replace the need of expensive battery by harnessing power from heart vibrations to drive the pacemaker system to measure the real-time Blood Pressure of the patient and to produce an alarm by pre-sensing the probability of possible heart-failure or heart-disease.

Published: March 2021

AbstractTill date millions of people are already infected by the Severe Acute Respiratory Syndrome Coronavirus (SARS-CoV-2). Situation is getting worse day-by-day due to lack of efficient Drug or Vaccine. It is already established that few compounds ofAchyranthes asperaextract have significant anti-HIV activity. Present study examines inhibitory efficiency of 8 anti-HIV compounds ofA. asperaextract against SARS-Cov-2. Angiotensin converting enzyme-2 (ACE-2) of Human body, RNA-dependent RNA polymerase (RdRp) and Main protease (Mpro) of SARS-CoV-2 have been chosen as targets for this study. The binding energies and inhibition constant values of these 8 compounds have been compared with the three drugs (Chloroquine, Hydroxychloroquine and Remdesivir). Most of the compounds showed good binding energies and inhibition constant values compared to the drugs. Excretion and Toxicity (ADMET) profile also reflected that the hits from our analysis are safe. According to the molecular docking study, among these 8 anti-HIV compounds, Oleanolic acid has the highest binding affinity and low inhibition constant value with the three proteases. So, we believe that this study will help in therapeutic efforts against SARS-CoV-2.
