A Power Associative Loop Structure for the Construction of Non-Linear Components of Block Cipher
( Institute of Electrical and Electronics Engineers Inc. , 2020 , Article)In the symmetric key cryptography, the purpose of the substitution box is to generate confusion and hence improve the security of the whole cryptosystem. For this reason, many algebraic substitution boxes are constructed ... -
A new Tikhonov-TV regularization for optical flow computation
( SPIE , 2020 , Conference)Tikhonov regularization and total variation (TV) are two famous smoothing techniques used in variational image processing problems and in particular for optical flow computation. We consider a new method that combines these ... -

Characterizing key attributes of COVID-19 transmission dynamics in China's original outbreak: Model-based estimations
( Elsevier , 2020 , Article)A novel coronavirus strain, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), emerged in China. This study aims to characterize key attributes of SARS-CoV-2 epidemiology as the infection emerged in China. An ... -
Manganese selenide: Synthetic aspects and applications
( Elsevier , 2020 , Article Review)This article deals with the synthetic strategies and applications of manganese selenide. Manganese selenide has been fabricated over the years with thermal evaporation at reduced pressure, solid state reactions, hydrothermal ... -
Solving multi-point boundary value problems using sinc-derivative interpolation
( MDPI AG , 2020 , Article)In this paper, the Sinc-derivative collocation method is used to solve linear and nonlinear multi-point boundary value problems. This is done by interpolating the first derivative of the unknown variable via Sinc numerical ... -
Metal telluride nanotubes: Synthesis, and applications
( Elsevier , 2020 , Article)Metal tellurides have been explored extensively just like their sulfide and selenide cousins due to their surface chemistry, quantum confinement and physical properties. Nanotubular metal tellurides are more promising in ... -
Analysis of COVID-19 Cases' Spatial Dependence in US Counties Reveals Health Inequalities
( Frontiers Media S.A. , 2020 , Article)On March 13, 2020, the World Health Organization (WHO) declared the 2019 coronavirus disease (COVID-19) caused by the novel coronavirus SARS-CoV2 a pandemic. Since then the virus has infected over 9.1 million individuals ... -
Generalized Littlewood-Paley Functions on Product Spaces
( TUBITAK , 2020 , Article)We are interested in investigating the L p boundedness of the product of generalized Littlewood–Paley functions S (λ) Φ (f) arising from kernels satisfying only size and cancellation conditions. We obtain L p estimates ... -
Extensive use of face masks during COVID-19 pandemic: (micro-)plastic pollution and potential health concerns in the Arabian Peninsula
( Elsevier , 2020 , Article)Face masks are primary line of defense to reduce the transmission risk of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). World Health Organization (WHO) has already updated the guidelines and advised the use ... -
𝜆-point anomaly in view of the seven-loop hypergeometric resummation for the critical exponent 𝜈 of the 𝑂(2) 𝜙4 model
( American Physical Society , 2020 , Article)In this work, we use a specific parametrization of the hypergeometric approximants [the one by Mera et al. in Phys. Rev. Let. 115, 143001 (2015)] to approximate the seven-loop critical exponent 𝜈 for the 𝑂(2)-symmetric ... -
A proximal point algorithm converging strongly to a minimizer of a convex function
( Yarmouk University , 2020 , Article)In this paper, we obtain a new modified proximal point algorithm in the setting of CAT(0) spaces and establish some strong convergence results of the proposed algorithm. In process, several relevant results of the existing ... -
Two bregman projection methods for solving variational inequality problems in hilbert spaces with applications to signal processing
( MDPI , 2020 , Article)Studying Bregman distance iterative methods for solving optimization problems has become an important and very interesting topic because of the numerous applications of the Bregman distance techniques. These applications ... -
Weak-coupling, strong-coupling and large-order parametrization of the hypergeometric-Meijer approximants
( Elsevier , 2020 , Article)Without Borel or Padé techniques, we show that for a divergent series with n! large-order growth factor, the set of hypergeometric series pFp-2 represents suitable approximants. The divergent pFp-2 series are then resummed ... -
Severe dehydration among cholera patients in Yemen: A cohort profile
( European Academy of HIV/AIDS and Infectious Diseases , 2020 , Article)Introduction Cholera, an acute diarrheal illness caused by ingestion of food or water contaminated with Vibrio cholerae, is one of the major causes of morbidity and mortality globally. The occurrence of outbreaks of cholera ... -
Some escape time results for general complex polynomials and biomorphs generation by a new iteration process
