Complex shaping of the depth of focus
(Optical Society of America, 2020)
In this manuscript an exact solution to the inverse problem of axial beam shaping along the focus of a convergent lens is found. This allows to extend, within the framework of the scalar theory of diffraction, the mathematical ...
Homomorphic Encoders of Profinite Abelian Groups II
(MDPI, 2022-03-29)
Let {Gi:i∈N} be a family of finite Abelian groups. We say that a subgroup G≤∏i∈NGi is order controllable if for every i∈N, there is ni∈N such that for each c∈G, there exists c1∈G satisfying c1|[1,i]=c|[1,i], supp(c1)⊆[1,ni], ...
Spatio-temporal prediction of Baltimore crime events using CLSTM neural networks
(IEEE, 2020-11-09)
Crime activity in many cities worldwide causes significant damages to the lives of victims and their surrounding communities. It is a public disorder problem, and big cities experience large amounts of
crime events. ...
Dynamics of Fractional Vortex Beams at Fraunhofer Diffraction Zone
(MDPI, 2022-07-09)
Fractional vortex beams (FVBs) possess unique topological properties that are manifested in the vortex distribution. However, there are still discrepancies in the value of the vortex strength of FVBs at the far field. In ...
Air Quality Prediction in Smart Cities Using Machine Learning Technologies Based on Sensor Data: A Review
(MDPI, 2020-04-01)
The influence of machine learning technologies is rapidly increasing and penetrating almost in every field, and air pollution prediction is not being excluded from those fields. This paper covers the revision of the studies ...
A lower bound for the area of Plateau foams
(Springer, 2020-04-07)
Real foams can be viewed as geometrically well-organized dispersions of more or less spherical bubbles in a liquid. When the foam is so drained that the liquid content significantly decreases, the bubbles become polyhedral-like ...
Easily Solving Dynamic Programming Problems in Haskell by Memoization of Hylomorphisms
(Wiley, 2020)
Dynamic Programming is a well known algorithmic technique that solves problems
by a combination of dividing a problem into subproblems and using memoization
to avoid an exponential growth of the costs. We show how to ...
Understanding the sharing economy and its implication on sustainability in smart cities
(Elsevier, 2020-09-06)
The purpose of this article is to evaluate the main drivers of the sharing economy through an exhaustive
weighting and meta-analysis of previous relevant quantitative research articles, obtained using a systematic literature ...
Smartphone Apps for the Treatment of Mental Disorders: Systematic Review
(JMIR Publications, 2020-04-02)
Background: Smartphone apps are an increasingly popular means for delivering psychological interventions to patients suffering from a mental disorder. In line with this popularity, there is a need to analyze and summarize ...
Inactivation of SARS-CoV-2 by a chitosan/α-Ag2WO4 composite generated by femtosecond laser irradiation
(Nature Research, 2022)
In the current COVID‑19 pandemic, the next generation of innovative materials with enhanced anti‑
SARS‑CoV‑2 activity is urgently needed to prevent the spread of this virus within the community.
Herein, we report the ...
