Simulate the behavior of graphene in external electric fields
Authors: Панферов Анатолий Дмитриевич , Новиков Николай Андреевич , Трунов Александр Алексеевич
Published: March 2021

В работе представлены результаты, полученные при разработке программного комплекса для вычисления наблюдаемых параметров монослойного графена в условиях действия на него внешнего электрического поля. Используемая физическая модель позволяет детально воспроизводить такие параметры, но требует большого объёма вычислений для получения точных значений. Основой модели является система кинетических уравнений, обеспечивающих вычисление зависящей от времени функции распределения носителей заряда в двумерном импульсном пространстве. Требуемые вычислительные ресурсы пропорциональны количеству узлов расчетной сетки, покрывающей импульсное пространство. Характер поведения модели позволяет использовать локальные сетки, покрывающие только относительно небольшую часть полной области определения вычисляемой функции.

Применительно к моделированию результатов действия коротких высокочастотных импульсов электрического поля показано, что анализ поведения модели при максимальном уровне внешнего поля может использоваться для поиска и локализации областей в импульсном пространстве, определение функции распределения в которых достаточно для получения значений наблюдаемых. Даже в условиях действия слабых внешних электрических полей область локализации функции распределения можно определять по результатам вычисления её значений на относительно разреженных сетках.

Получение наблюдаемых параметров основано на вычислении интегральных характеристик функции распределения в двумерном импульсном пространстве. Реализация такого интегрирования одновременно с вычислением в параллельном режиме значений функции распределения на оптимизированной сетке избавляет от ненужного сохранения значений функции распределения, выдавая на выходе одномерные временные ряды, представляющие данные о динамике наблюдаемых параметров, интересных с точки зрения анализа поведения рассматриваемой модели.

Electrode Configurations for fast separation of trapped ions
Authors: Home J.P. , Steane A.M.
Published: March 2021

We study the problem of designing electrode structures that allow pairs of ions to be brought together and separated rapidly in an array of linear Paul traps. We show that it is desirable for the electrode structure to produce a d.c. octupole moment with an a.c. radial quadrupole. For the case where electrical breakdown limits the voltages that can be applied, we show that the octupole is more demanding than the quadrupole when the characteristic distance scale of the structure is larger than 1 to 10 microns (for typical materials). We present a variety of approaches and optimizations of structures consisting of one to three layers of electrodes. The three-layer structures allow the fastest operation at given distance \rho from the trap centres to the nearest electrode surface, but when the total thickness w of the structure is constrained, leading to w < \rho, then two-layer structures may be preferable.

A logarithmic-depth quantum carry-lookahead adder
Authors: Draper T.G. , Kutin S.A. , Rains E.M. , Svore K.M.
Published: March 2021

We present an efficient addition circuit, borrowing techniques from classical carry-lookahead arithmetic. Our quantum carry-lookahead (\QCLA) adder accepts two n-bit numbers and adds them in O(\log n) depth using O(n) ancillary qubits. We present both in-place and out-of-place versions, as well as versions that add modulo 2^n and modulo 2^n - 1. Previously, the linear-depth ripple-carry addition circuit has been the method of choice. Our work reduces the cost of addition dramatically with only a slight increase in the number of required qubits. The \QCLA\ adder can be used within current modular multiplication circuits to reduce substantially the run-time of Shor's algorithm.
The distillability problem revisited
Authors: Clarisse L.
Published: March 2021

An important open problem in quantum information theory is the question of the existence of NPT bound entanglement. In the past years, little progress has been made, mainly because of the lack of mathematical tools to address the problem. (i) In an attempt to overcome this, we show how the distillability problem can be reformulated as a special instance of the separability problem, for which a large number of tools and techniques are available. (ii) Building up to this we also show how the problem can be formulated as a Schmidt number problem. (iii) A numerical method for detecting distillability is presented and strong evidence is given that all 1-copy undistillable Werner states are also 4-copy undistillable. (iv) The same method is used to estimate the volume of distillable states, and the results suggest that bound entanglement is primarily a phenomenon found in low dimensional quantum systems. (v) Finally, a set of one parameter states is presented which we conjecture to exhibit all forms of distillability.
Characterization of several kinds of quantum analogues of relative entropy
Authors: Hayashi M.
Published: March 2021

Quantum relative entropy $D(\rho\|\sigma)\defeq\Tr \rho (\log \rho- \log \sigma)$ plays an important role in quantum information and related fields. However, there are many quantum analogues of relative entropy. In this paper, we characterize these analogues from information geometrical viewpoint. We also consider the naturalness of quantum relative entropy among these analogues.
Teleportation via multi-qubit channels
Authors: Links J. , Barjaktarevic J.P. , Milburn G.J. , Mckenzie R.H.
Published: March 2021

We investigate the problem of teleporting an unknown qubit state to a recipient via a channel of $2{\mathcal L}$ qubits. In this procedure a protocol is employed whereby ${\mathcal L}$ Bell state measurements are made and information based on these measurements is sent via a classical channel to the recipient. Upon receiving this information the recipient determines a local gate which is used to recover the original state. We find that the $2^{2\mathcal L}$-dimensional Hilbert space of states available for the channel admits a decomposition into four subspaces. Every state within a given subspace is a perfect channel, and each sequence of Bell measurements projects $2{\mathcal L}$ qubits of the system into one of the four subspaces. As a result, only two bits of classical information need be sent to the recipient for them to determine the gate. We note some connections between these four subspaces and ground states of many-body Hamiltonian systems, and discuss the implications of these results towards understanding entanglement in multi-qubit systems.

Published: March 2021

Mucus secretion by intestinal goblet cells constitutes an important mechanism in TH2 response following helminth infection mediated by the key cytokine IL-22. This indirect mechanism rather than directly attacking the parasite is important in preventing helminth attachment hence promoting helminth expulsion from the intestinal tract. We hypothesized that natural products having an anthelmintic activity like caprine milk may exert similar response. Using human intestinal LS174T cells treated with IL-22 to simulate helminth infection, we tested whether or not the co-treatment with caprine milk induces MUC1, MUC3, MUC4 and MUC5B genes expression. Optimal concentrations for caprine milk was determined to be 25% and 50% from cell viability assay. IL-22 induced helminth infection model was confirmed. However, the indirect anthelmintic effect of caprine milk was only relative as treatment of caprine milk in LS174T cells and IL-22 in vitro did not significantly induce MUC1, MUC3, MUC4 and MUC5B genes expression when compared to treatment with IL-22 alone. In conclusion, caprine milk was not significantly associated with the mechanism of increased mucus production through upregulation of mucin genes by intestinal cells. Caprine milk may possess direct anthelmintic effect rather than indirect.

Spontaneous regression (SR) is defined as complete or partial disappearance of a proven malignant tumor without adequate medical treatment. Although there have been reports on SR of breast cancers, this phenomenon remains rare. We report a case of SR of breast cancer in a 62-year-old woman who presented to our hospital with a few months history of a painless breast lump. Initial radiological investigations reveal a suspicious mass in the left upper outer quadrant. Histopathology confirms the presence of invasive cancer. The patient initially refused any surgical or medical interventional and defaulted follow-up. The patient presented again after four months with consent for surgical treatment. Repeat ultrasound just before the hook wire localization procedure demonstrated the absence of tumor in the region of interest. The subsequent repeat mammogram and MRI also demonstrated complete regression of breast cancer. MRI however, does reveal a suspicious left axillary lymph node, which was also deemed suspicious on PET-CT. In view of these findings, the patient was counsel for surgery. The exact mechanism of SR of cancer remains unclear in our patient. We are unable to identify the exact mechanism triggering and influencing the SR in our patient. Our hypotheses include substance within the herbal remedies or a carcinoma-directed immune response triggered by the biopsy. Further research is needed to determine causes for spontaneous regressions of cancer and towards finding a possible cure for cancer.

Published: March 2021

A gastrointestinal stromal tumour (GIST) is a tumor of the gastrointestinal tract. We present a 36-year-old, gravida 2 para 1 lady presented with acute lower abdominal pain at 9 weeks period of amenorrhea (POA) associated with vomiting. She had a previous uncomplicated cesarean section 2 years ago. Abdominal examination revealed a tender and mobile 26-week-sized mass. A transabdominal scan revealed a right adnexal mass with a cystic component measuring 10 cm x 10 cm in size, as well as a viable singleton intrauterine fetus corresponding to her dates. She underwent emergency laparotomy in suspicion of a right twisted ovarian cyst. The inoperative finding revealed a large pedunculated and twisted gangrenous mass from the greater curvature of the stomach with normal uterus and ovaries. The histopathological examination of the mass reported as malignant Sarcomatoid epithelioid GIST (category 3b). The patient was managed by a multidisciplinary team approach involving the obstetrician & gynaecologist, surgeon and oncologist throughout her pregnancy course. The pregnancy progressed well, and she delivered via elective repeat cesarean section. Post partumly, oesophago-gastric-duodeno-scopy and computed tomography assessment revealed no evidence of local disease or distant metastasis. She was advised for yearly follow-up with the surgical department.

Published: March 2021

Increased prevalence of inherited genetic disorders is a significant public health problem that significantly affects the quality of life of the affected patients and their families in Arab countries. Knowledge about the disorders may empower the community by raising awareness about prevention methods and early detection to reduce the incidence of genetic disorders. This study was aimed to assess the knowledge and attitude related to inherited genetic disorders among health science university students in Ras Al Khaimah. A cross-sectional study was carried out for six months among health science university students in Ras Al Khaimah by using a validated self-administered questionnaire. A total of 359 students completed the study. The overall mean knowledge and attitude scores of the study respondents were 4.47 ± 1.81 and 5.37 ± 2.32, respectively. One hundred and six (29.5%) respondents had adequate knowledge, and a majority (74.65%) of the respondents showed a positive attitude towards genetic disorders. Lectures (25.5%) followed by the internet (20.7%) and healthcare professionals (15.7%) were the most cited sources of information. Comprehensive knowledge about genetic disorders was found to be low despite positive attitude and awareness among respondents. Strengthening knowledge about genetic education and mandatory premarital screening programs may help in early detection and prevention and thereby reducing the incidence of genetic disorders.

Published: March 2021

In today's world, with ever-increasing safety requirements, there is a growing demand to maintain or reduce production costs. In aviation, in addition to factors like weight and related variables such as resistance to vibration, corrosion, temperature and other are also considered. The task of this paper is to analyse unconventional designs of wing beams with respect to the current requirements of the aviation industry. In the article, the authors analyse the possibilities of design modification either by adding ribs to the profile, or by changing the cross-section of the profile itself. In practice, such design changes would increase weight, production time and finances, but also increase strength and thus safety. All proposed changes were subjected to strength analyses by FEM (Finite element method) computer simulations. The article output is the selection of suitable designs for further observation and experimental verification to ensure comprehensive results for the possibility of implementation in practice. Despite the non-traditional shapes of the proposed wing beam cross-sections, the authors assume that traditional beam shapes will be gradually modified more efficiently.

Published: March 2021

The paper deals with the legislation in the field of unmanned aircraft systems (UAS) in the Slovak Republic. The main goal of the paper is to analyse the current legislative framework, which sets the basic rules and restrictions. The article’s contribution is a description of the latest Implementing Regulation (EU) 2019/947. The solution to the issue consists of an analysis of the requirements for changes in current legislation based on people’s experience from practice. The reason for the changes is to facilitate flying with UAS for all user groups, provided that safety is maintained, and risks are minimised. These new regulations are causing the most significant changes, especially for organisations that will perform aerial work with the UAS in the Specific category. These organisations need to transform their operations manuals and extend the aerial work system with a risk analysis.

Autonomous algorithms for monitoring the integrity of the navigation field in relation to GNSS GLONASS
Authors: Leonidov N. V.
Published: March 2021

The purpose of this article is to analyze the existing algorithms of autonomous control of the integrity of the navigation field of the GLONASS system. The analysis is based on domestic materials and official foreign applications. At the beginning of the article, the concept of the integrity of the global navigation satellite system is given in the form in which it is used in International Civil Aviation Organization and among the developers of such systems. The differences between the common types of control of the integrity of the navigation field are shown. The modeling of individual operational characteristics, including the average geometric factor, visibility, and accessibility for different angles of the site, is carried out. The main solutions to the problem of reduced tactical and technical characteristics of the system are compared. The existing prerequisites for the improvement of the GLONASS system and for the use of small navigation spacecraft to eliminate the gap between GLONASS and competing global navigation satellite systems are listed. As a result, a variant of improving the circumstances for the application of these algorithms in unfavorable conditions in relation to the GLONASS system is proposed. It is shown that the low-orbit addition to the GLONASS system can significantly improve the tactical and technical characteristics of the complex as a whole and provide higher reliability of the system as a whole due to the operational maintenance of the integrity of the navigation field.

Authors: Chebotarev V. E. , Zimin I. I. , Vnukov A. A.
Published: March 2021

The topical problem of choosing the standard size of the unified space platform developed by the joint-stock company «Academician M. F. Reshetnev» Information Satellite Systems» for geostationary communication satellites has been formulated. Previously, the task of assessing the effectiveness of using the developed unified platforms for creating a new spacecraft was solved to a greater extent empirically, by generalizing the groundwork for existing developments and assessing the possibility and feasibility of using the existing groundwork in the future (development continuity). However, a methodological basis for solving this kind of problem has not yet been developed. As part of the study, a model for assessing the efficiency of a spacecraft based on a unified space platform was developed. A method for evaluating the effectiveness of the use of unified space platforms with an excess resource (in terms of mass and energy consumption) for the payload and a method for evaluating the effectiveness of using a modernized unified space platform, which makes it possible to meet increased resource requirements (in terms of weight and energy consumption) for the payload, have been developed. With the help of the developed methods, the assessment of the range of effective use of a unified space platform for geostationary communication satellites developed by JSC ISS was carried out, both without revision and with the necessary modernization for a specific project (payload).

The article presents a cross-lingual diachronic analysis of the linguistic image of Kazan recorded in Russian and English Corpora of Google Books within the period between years 1800 and 2019. The material of the research comprises 6236 texts in the Russian subcorpus and 9858 texts in the English subcorpus compiled for the study. The frequency of onym ‘Казань’ was the highest in early 19th and 20th centuries, while that of ‘Kazan’ – in late 20th century. The range of lexical patterns of both Russian English contexts of the studied words is wide with predominantly neutral and, in rare cases, negative connotations in the past, while modern contexts are most notably positive and neutral. In both languages subcorpora, the highest context frequency is registered for the words belonging to the following thematic groups: “City”, “Historical personality”, “Landscape”, “Religion”, as well as verbs denoting acquisition of an object and adjectives denoting time. The range of typical semantic roles of the onyms ‘Казань’ and ‘Kazan’ during the period studied, 1800–2019, widens from Locative and Patient in the texts of the 19th century to Agent, Posessor, Experiencer in the 20th and 21st centuries. The latter is caused by changes in the national and global arena and the role of Kazan in the country and the world. The research shows that, in the modern discourse, the word collocates with the verbs denoting activity, verbal behavior, physical action, and struggle. The article also provides the authors’ insights into the limitations of the corpus used as the source of research.

Africans had been producing fabrics locally before the advent of Western fabrics. Àdìrẹ fabrics are purely African textile concepts; dyed with local/indigenous materials and readymade synthetic materials in Abẹ́òkúta, Òṣogbo, Ìbàdàn, Kánò, Ṣókótó, and other parts of Nigeria, and Africa at large. The study focuses on how leaves, bark of plants, and trees are utilized in producing colors of dyes. For example, shade of red can be obtained from leaves of guinea corn (sorghum village), leave of teak wood (tectona grands), leaves of henna law (Sonia intermis), bark and roots of African rose wood (ptrocerpus erinaceus), and wood of the came wood “osùn” (baphia nitida). The sap of old physic nut tree (fatopha curca) produces a black dye. Likewise, many other colours are produced when the need arises. When yellow is desired, afromosia taxifora or a root wood (Morinda lucida) or group grand are used. The mango tree bark, when dried and boiled with water gives a brown dye. Two other fruits Kigelia African and vitex grandifolia are also used for dye. There is an argument on which of the colour registered fast, is it the natural dye or the imported synthetic dye? The answer probably lies in the method of preparing and implementing the dye and the skill/creativity of the dyer. The study examines the utilization of local and synthetic indigo dyes and quality of dyed cotton fabric in Ìtòkú market, Abẹ́òkúta, Ògùn State. Some participants were interviewed, and questionnaires were administered to respondents for data collection. The result of hypothesis tested justify that there is no significant difference between utilisation of local and imported dye in the quality of textile in relation to colours. Results and findings were discussed, comparism between the local and synthetic dyes was concluded and recommendations were made
