Optimal ancilla-free Clifford+V approximation of z-rotations
Authors: Ross Neil J.
Published: February 2021

We describe a new efficient algorithm to approximate $z$-rotations by ancilla-free Clifford+$V$ circuits, up to a given precision $\epsilon$. Our algorithm is optimal in the presence of an oracle for integer factoring: it outputs the shortest Clifford+$V$ circuit solving the given problem instance. In the absence of such an oracle, our algorithm is still near-optimal, producing circuits of $V$\!-count $m + O(\log(\log(1/\epsilon)))$, where $m$ is the $V$\!-count of the third-to-optimal solution. A restricted version of the algorithm approximates $z$-rotations in the Pauli+$V$ gate set. Our method is based on previous work by the author and Selinger on the optimal ancilla-free approximation of $z$-rotations using Clifford+$T$ gates and on previous work by Bocharov, Gurevich, and Svore on the asymptotically optimal ancilla-free approximation of $z$-rotations using Clifford+$V$ gates.
Modular quantum memories using passive linear optics and coherent feedback
Authors: Nurdin Hendra I. , Gough John E.
Published: February 2021

In this paper, we show that quantum memory for qudit states encoded in a single photon pulsed optical field has a conceptually simple modular realization using only passive linear optics and coherent feedback. We exploit the idea that two decaying optical cavities can be coupled in a coherent feedback configuration to create an internal mode of the coupled system which is isolated and decoherence-free for the purpose of qubit storage. The qubit memory can then be switched between writing/read-out mode and storage mode simply by varying the routing of certain freely propagating optical fields in the network. It is then shown that the qubit memories can be interconnected with one another to form a qudit quantum memory. We explain each of the phase of writing, storage, and read-out for this modular quantum memory scheme. The results point a way towards modular architectures for complex compound quantum memories.
Spatial search on grids with minimum memory
Authors: Ambainis Andris , Portugal Renato , Nahimov Nikolay
Published: February 2021

We study quantum algorithms for spatial search on finite dimensional grids. Patel \textit{et al.}~and Falk have proposed algorithms based on a quantum walk without a coin, with different operators applied at even and odd steps. Until now, such algorithms have been studied only using numerical simulations. In this paper, we present the first rigorous analysis for an algorithm of this type, showing that the optimal number of steps is $O(\sqrt{N\log N})$ and the success probability is $O(1/\log N)$, where $N$ is the number of vertices. This matches the performance achieved by algorithms that use other forms of quantum walks.
Limitations of single coset states and quantum algorithms for code equivalence
Authors: Dinh Hang , Moore Cristopher , Russell Alexander
Published: February 2021

Quantum computers can break the RSA, El Gamal, and elliptic curve public-key cryptosystems, as they can efficiently factor integers and extract discrete logarithms. The power of such quantum attacks lies in \emph{quantum Fourier sampling}, an algorithmic paradigm based on generating and measuring coset states. %This motivates the investigation of the power or limitations of quantum Fourier sampling, especially in attacking candidates for ``post-quantum'' cryptosystems -- classical cryptosystems that can be implemented with today's computers but will remain secure even in the presence of quantum attacks. In this article we extend previous negative results of quantum Fourier sampling for Graph Isomorphism, which corresponds to hidden subgroups of order two (over S_n, to several cases corresponding to larger hidden subgroups. For one case, we strengthen some results of Kempe, Pyber, and Shalev on the Hidden Subgroup Problem over the symmetric group. In another case, we show the failure of quantum Fourier sampling on the Hidden Subgroup Problem over the general linear group GL_2(\FF_q). The most important case corresponds to Code Equivalence, the problem of determining whether two given linear codes are equivalent to each other up to a permutation of the coordinates. Our results suggest that for many codes of interest---including generalized Reed Solomon codes, alternant codes, and Reed-Muller codes---solving these instances of Code Equivalence via Fourier sampling appears to be out of reach of current families of quantum algorithms.
Exact quantum algorithms have advantage for almost all Boolean functions
Authors: Ambainis Andris , Gruska Jozef , Zheng Shenggen
Published: February 2021

It has been proved that almost all n-bit Boolean functions have exact classical query complexity n. However, the situation seemed to be very different when we deal with exact quantum query complexity. In this paper, we prove that almost all n-bit Boolean functions can be computed by an exact quantum algorithm with less than n queries. More exactly, we prove that ANDn is the only n-bit Boolean function, up to isomorphism, that requires n queries.
Analysis of circuit imperfections in BosonSampling
Authors: Leverrier Anthony , Garcia-Patron Raul
Published: February 2021

BosonSampling is a problem where a quantum computer offers a provable speedup over classical computers. Its main feature is that it can be solved with current linear optics technology, without the need for a full quantum computer. In this work, we investigate whether an experimentally realistic BosonSampler can really solve BosonSampling without any fault-tolerance mechanism. More precisely, we study how the unavoidable errors linked to an imperfect calibration of the optical elements affect the final result of the computation. We show that the fidelity of each optical element must be at least 1 − O(1/n^2 ), where n refers to the number of single photons in the scheme. Such a requirement seems to be achievable with state-of-the-art equipment.
Jordan-Wigner formalism for arbitrary 2-input 2-output matchgates and their classical simulation
Authors: Jozsa Richard , Miyake Akimasa , Strelchuk Sergii
Published: February 2021

In Valiant's matchgate theory, 2-input 2-output matchgates are $4\times 4$ matrices that satisfy ten so-called matchgate identities. We prove that the set of all such matchgates (including non-unitary and non-invertible ones) coincides with the topological closure of the set of all matrices obtained as exponentials of linear combinations of the 2-qubit Jordan-Wigner (JW) operators and their quadratic products, extending a previous result of Knill. In Valiant's theory, outputs of matchgate circuits can be classically computed in poly-time. Via the JW formalism, Terhal \& DiVincenzo and Knill established a relation of a unitary class of these circuits to the efficient simulation of non-interacting fermions. We describe how the JW formalism may be used to give an efficient simulation for all cases in Valiant's simulation theorem, which in particular includes the case of non-interacting fermions generalised to allow arbitrary 1-qubit gates on the first line at any stage in the circuit. Finally we give an exposition of how these simulation results can be alternatively understood from some basic Lie algebra theory, in terms of a formalism introduced by Somma et al.
Quantum relay cooperative communication via space-time transmission
Authors: Shi Jinjing , Shi Ronghua , Peng Xiaoqi , Guo Ying , Lee Moon Ho
Published: February 2021

Two novel quantum relay cooperative communication schemes $1S2R1D$ and $2S2R2D$ are proposed by applying the wireless communication technique in the quantum system. The orthogonal quantum signals in consecutive quantum sequences are prepared to avoid mutual interference and they are firstly transmitted to the quantum relay node and then to the destination node with space-time transmission. Moreover, quantum operations and transformations are implemented on the relay node and the destination node to maximize the correct information transmission. The fidelity between original and final received signals, the security, the quantum bit error rate and the lower bound on the capacity of quantum relay channels are analyzed. Especially it provides a valuable application prospect in long distance reliable quantum communications.

An in-depth performance analysis of the oversampling techniques for high-class imbalanced dataset
Authors: Wibowo Prasetyo , Fatichah Chastine
Published: February 2021

Class imbalance occurs when the distribution of classes between the majority and the minority classes is not the same. The data on imbalanced classes may vary from mild to severe. The effect of high-class imbalance may affect the overall classification accuracy since the model is most likely to predict most of the data that fall within the majority class.  Such a model will give biased results, and the performance predictions for the minority class often have no impact on the model. The use of the oversampling technique is one way to deal with high-class imbalance, but only a few are used to solve data imbalance. This study aims for an in-depth performance analysis of the oversampling techniques to address the high-class imbalance problem. The addition of the oversampling technique will balance each class’s data to provide unbiased evaluation results in modeling. We compared the performance of Random Oversampling (ROS), ADASYN, SMOTE, and Borderline-SMOTE techniques. All oversampling techniques will be combined with machine learning methods such as Random Forest, Logistic Regression, and k-Nearest Neighbor (KNN). The test results show that Random Forest with Borderline-SMOTE gives the best value with an accuracy value of 0.9997, 0.9474 precision, 0.8571 recall, 0.9000 F1-score, 0.9388 ROC-AUC, and 0.8581 PRAUC of the overall oversampling technique.

Published: February 2021

The world of banking requires a marketer to be able to reduce the risk of borrowing by keeping his customers from occurring non-performing loans. One way to reduce this risk is by using data mining techniques. Data mining provides a powerful technique for finding meaningful and useful information from large amounts of data by way of classification. The classification algorithm that can be used to handle imbalance problems can use the Random Forest (RF) algorithm. However, several references state that an optimization algorithm is needed to improve the classification results of the RF algorithm. Optimization of the RF algorithm can be done using Bagging and Genetic Algorithm (GA). This study aims to classify Bank Marketing data in the form of loan application receipts, which data is taken from the www.data.world site. Classification is carried out using the RF algorithm to obtain a predictive model for loan application acceptance with optimal accuracy. This study will also compare the use of optimization in the RF algorithm with Bagging and Genetic Algorithms. Based on the tests that have been done, the results show that the most optimal performance of the classification of Bank Marketing data is by using the RF algorithm with an accuracy of 88.30%, AUC (+) of 0.500 and AUC (-) of 0.000. The optimization of Bagging and Genetic Algorithm has not been able to improve the performance of the RF algorithm for classification of Bank Marketing data.

Accounting and Analysis of Cash Flows of Penal Entities
Authors:   Baikal State University, Irkutsk 664003, Russian Federation, Arbatskaya Tatyana G.
Published: February 2021

The global economic crisis, exacerbated by the pandemic of the new coronavirus infection, has led to a significant deterioration in the financial state of most economic entities. This problem has also affected public sector entities receiving budget financing. Even if a given public sector entity is engaged in entrepreneurial activity, with a decrease in sales cash flow decreases, whereas accounts receivable and payable increase. To carry out their statutory activities, state entities of the penitentiary system in the Russian Federation use not only budgetary funds, but also funds received from the sale of products manufactured by convicts. Therefore, the interest of users in the cash flows of penitentiary institutions is steadily increasing. The above strengthens the information and analytical functions of cash flow statements. Unlike other forms of reporting, the cash flow statement should report cash flows during the period classified by operating and investing activities (financing activity is not typical for penitentiary entities). In addition, the statement of cash flows provides useful information not only for controlling the use of budget funds, but also for current and forecast analysis. The article investigates the theoretical principles of accounting of cash flows of public sector entities of the penitentiary system of the Russian Federation. Results of the study include a proposal to improve the form of the cash flow statement by including an analytical feature — the source of financing activities. The study also presents and tests a methodology for analyzing cash flows in the context of funding sources.

Instruments of time series analysis were used to test a proposition that the Russian ruble’s exchange rate has become less dependent on Brent crude oil price in recent years. We obtained 1,095 weekly observations for years 2000 to 2020 were obtained from FINAM company website. Our empirical model is a linear regression of the ruble’s exchange rate on Brent crude oil price. The Bai-Perron test has identified three structural breaks in the data corresponding to four chronological regimes. The Engle-Granger cointegration test has found both the rate and the price to be non-stationary in all regimes while cointegration was found only in the third regime (September 12, 2011 – October 23, 2017). The main reasons for collapse of cointegration in the fourth regime (October 30, 2017 – December 28, 2020) are 1) successful efforts by oil-producing countries to curb oil production, 2) decline in Russian import of goods and services, 3) Bank of Russia’s contractionary monetary policy, 4) built-in exchange rate stabilizer activated by the budget rule, and 5) anti-Russian sanctions. Cointegration, as it turns out, comes and goes.

Metastasis to the brain is a clinical problem in patients with breast cancer (1-3). Between the breast and the brain reside the secondary lymphoid organ, the lymph nodes. We mined published microarray data (4, 5) to compare primary and metastatic tumor transcriptomes for the discovery of genes associated with metastasis to the lymph nodes in humans with metastatic breast cancer. We found that natural cytotoxicity triggering receptor 3, NCR3, was among the genes whose expression was most different in the lymph node metastases of patients with metastatic breast cancer as compared to primary tumors of the breast. Analysis of a separate microarray dataset revealed that NCR3 was also differentially expressed in brain metastatic tissues. NCR3 mRNA was present at increased quantities in lymph node metastases as compared to primary tumors of the breast. Importantly, expression of NCR3 in primary tumors of the breast was significantly correlated with patient overall survival, in lymph node negative patients but not in lymph node positive patients. Modulation of NCR3 expression may be relevant to the biology by which tumor cells metastasize from the breast to the lymph nodes and the brain in humans with metastatic breast cancer.

Divulgar novos conhecimentos é relevantes para área de atuação deve ser a prioridade de um periódico científico. Para isso, faz-se necessária uma política editorial bem estruturada que garanta a sua qualidade e sustentabilidade. Neste contexto, objetivou-se com esse estudo analisar a política editorial dos periódicos da área de Ciência da Informação: Encontros Bibli e Biblionline e averiguar similaridades e diferenças de diretrizes de trabalho propostas por esses títulos e se influenciam no impacto de suas publicações e sua classificação em ferramentas de avaliação. Trata-se de uma pesquisa descritiva pelo fato de propor a descrição das características dos periódicos e estabelecer relações entre variáveis. Do ponto de vista dos procedimentos técnicos é uma pesquisa documental, uma vez que utiliza documentos já existentes e que não receberam tratamento analítico. O viés da análise é qualitativo, já que levanta dados que expõem a qualidade dos periódicos em análise. Para a coleta dos dados, as principais fontes foram o web site dos periódicos Biblionline e Encontros Bibli. Além disso, foi construído um instrumento com 10 critérios relacionados a editoração de revistas científicas. Como insumos tecnológicos utilizou de uma planilha colaborativa, um documento compartilhado no Google Drive e o Ucinet, que foi utilizado para a elaboração de gráficos. Considerou-se que a endogenia e indexadores são indícios de possíveis de impactos para os indicadores dos periódicos em análise. Conclui-se que uma política editorial robusta, transparente e bem estruturada é fundamental para o reconhecimento do periódico.
Do People Prescribe Optimism, Overoptimism, or Neither?

Published: February 2021

Past work has suggested that people prescribe optimism—believing it is better to be optimistic, instead of accurate or pessimistic, about uncertain future events. Here, we identified and addressed an important ambiguity about whether those findings reflect an endorsement of biased beliefs—i.e., whether people prescribe likelihood estimates that reflect overoptimism. In three studies, participants (total N = 663 U.S. university students) read scenarios about protagonists facing uncertain events with a desired outcome. Results replicated prescriptions of optimism when using the same solicitations as in past work. However, we found quite different prescriptions when using alternative solicitations that asked about potential bias in likelihood estimations and that did not involve vague terms like “optimistic.” Participants generally prescribed being optimistic, feeling optimistic, and even thinking optimistically about the events, but they did not prescribe overestimating the likelihood of those events.

The advent of Social Networking Sites (SNSs) has determined radical changes in human social life, demanding to deepen investigations on the mechanisms underlying socialization processes on online platforms. The knowledge acquired from previous studies on in-person sociability could guide researchers to consider both environmental and genetic features as candidates of the online socialization. In the current research, we explored the impact of the quality of adult attachment and the genetic properties of the Serotonin Transporter Gene (5-HTTLPR) on Instagram social behavior. Experiences in Close Relationships-Revised questionnaire was adopted to assess 57 Instagram users' attachment pattern in close relationship with their partner. Genotypes from the 5-HTTLPR/rs25531 region were extracted from the users' buccal mucosa and analyzed. Details on users' Instagram social behavior were acquired from four indexes: number of posts, number of followed users ("followings") and number followers, and the Social Desirability Index calculated from the followers to followings ratio.Although no interaction between rs25531 and ECR-R dimensions was found, results suggested an association between avoidance in close relationships and Instagram number of followings. Specifically, post-hoc analyses revealed that adult avoidance from the partner predicts the Instagram number of followings with good evidence. Moreover, users who reported high avoidance levels displayed fewer followings than users who reported low levels of avoidance.This research provides a window into the psychobiological understanding of online socialization on SNSs as Instagram.

Adults are biologically responsive to context, and their responses to particular situations may differ across cultures. However, are preschoolers’ biological systems also responsive to situational contexts and cultures? Here we show that children’s neurobiological stress responses, as indexed by salivary cortisol, are activated and responsive to psychosocial stressors relevant to their socio-cultural emphases. By examining cortisol changes across different contexts among 138 preschoolers living in the United States, China and Japan, we found that an achievement-related stressor elicited an increased cortisol response among Chinese preschoolers, whereas interpersonal-related stressors elicited an increased cortisol response among Japanese preschoolers. Contrastingly, US preschoolers showed decreased cortisol responses after these stressors, but consistently showed higher levels of anticipatory responses to separation at the beginning of each session. Our findings suggest that children’s neurobiological stress systems may be a critical biological mechanism allowing societal-level cultural phenomena to be embodied in individual-level responses, even amongst preschoolers.

A new virus, Severe Acute Respiratory Syndrome Corona Virus-2 (SARS CoV-2) emerged in December 2019 and still continuing to pose a great threat all over the Globe claiming to a fatality 980,031 persons. Among the human corona viruses it is the third one causing acute respiratory distress syndrome. The others two are SARS CoV and MERS CoV. The objective of this study is to review the human corona viruses causing severe respiratory distresses which are detected thru analysis of some recently published documents on the deadly SARS CoV-2 as well as information on SARS-CoV and MERS CoV from different world class trust worthy reliable and dependable sources. Genetic analysis reveals that the new human corona virus (SARS CoV-2) has similarities with the severe acute respiratory syndrome like (SARS like) bat virus which thought to be the primary reservoir. SARSCoV and MERS-CoV also have same bat reservoir but the intermediate host are different for three human corona viruses. Though the clinical picture is more or less similar but efficiency of human to human transmission is not same for these viruses. So, strict control measures are critical to contain this very big pandemic been occurring since December 2019. Everyday new information has been coming causing strategy to change to control this pandemic. Zoonotic origin of corona viruses indicate researchers, public health specialists should keep the continuous surveillance for early detection of new virus alike SARS –CoV-2.International Journal of Human and Health Sciences Vol. 05 No. 02 April’21 Page: 139-147
Contribution of al- Zahrawi (Albucasis) in the field of Pharmacy and Pharmacology with respect to his treatise Kitab al-Tasreef

Published: February 2021

Abūl-Qāsim Khalaf ibn ʿAbbās al-Zahrāwī Latinised as Abulcasis or Zahravius, lived between 936–1013 AD. He was born and raised in Al-Zahra a suburb of Córdoba (Arabic: Cortoba) in Spain. He was a famous surgeon, a talented pharmacist and a capable pharmacologist. Zahrawi is very famous for his surgical contribution, but this work explores his pharmaceutical and pharmacological contribution with respect to his treatise Kitab al-Tasreef. He served as the court physician to Caliph ʿAbd ar-Raḥmān III an-Nāṣir (912–961 AD). He wrote his famous book “Kitab al-Tasreef li-man ‘ajaza ‘an al-ta’lif” (The Arrangement of Medical Knowledge for one who is not able to compile it) around the year 1000 AD after fifty years of clinical experience. This book is also a chief source for indicating pharmaceutical contribution of al-Zahrāwī apart from the field of surgery. Twenty seven volumes, from Volume 3 to 29, of thirty volumes of the book Kitab al- Tasreef are related to Unani pharmacy and pharmacology. Ibn Abī Uṣaybiʿa (1203-1270 AD) remarked him only as an expert of pharmacy and pharmacology. Al-Zahrāwī devoted his entire life and genius to the advancement of pharmacy, medicine and surgery. He sketched a few drawings of pharmaceutical instruments and mentioned their use in his book. Significant pharmaceutical contributions of al-Zahrāwī are reflected by him through Kitab al-Tasreef which has not been highlighted, there is need to evaluate and emphasize the pharmaceutical contributions of al-Zahrāwī. This review is an attempt in this direction.International Journal of Human and Health Sciences Vol. 05 No. 03 July’21 Page: 276-285
