In the paper, a mathematical model for the description of the stress-strain state of mustard seeds during drying in the gas-suspended state under the pulsed action of the drying agent is constructed. Based on the obtained solutions of the problem, computer simulation of the stress-strain state of mustard seeds at an arbitrary time moment of drying has been performed to provide the maximally permissible parameters of drying mustard as seeding. As a result, the graphs of time distributions of displacements, deformations, and stresses in the structural elements of the grain of mustard have been constructed for the drying regime in the gas-suspended state under the pulsed action of the drying agent. © 2020 IEEE.

In this paper, we explore two different approaches to Big Data Mining: The Fuzzy Model Theory and the Formal Concept Analysis. We carry out the integration of these two approaches for solving the problem of constructing semantic models of domains. In the present paper, we focus on the third and fourth levels of sematic models, which formalizes via case models and fuzzy models of domains. We represent the basic notions of the FCA on the fuzzy model language and describe which formula extensions formal contexts allow us to find a new knowledge about the given domain. © 2019 IEEE.

Theranostics are crucial in both cancer diagnosis and targeted drug delivery, as they enable the simultaneous detection and treatment of disease within a single molecular or conjugated platform. However, theranostics is still facing challenges like real-time tracking for “where” prodrugs are activated in vivo , which poses a significant problem for molecule development. Organ-specific action to inspire the creation of innovative disease–curing technologies that are both accurate and efficient is still an underestimated task. We herein showcase the novel serendipitous gallbladder–targeting indole–based prodrug Indo–Gem for precise imaging-guided cancer therapy. Indo–Gem was prepared by an indole–malononitrile (dye) moiety, attached to the selected parent drug Gemcitabine via a disulfide cleavable linker. Indo–Gem is triggered by DTT with 27–fold fluorescent enhancement at pH 7.4, registering within 21 min. Unlike the most ignored adverse effects in prodrug activation, this indole–based dye targeting in a specific organ region of a zebrafish model via a combination of imaging ability and drug release. This is the first case that employs an indole–based moiety in prodrug design without any use of targeting ligands; the profound success of Indo–Gem and the well–defined mechanism suggest that the indole might serve as a scaffold to create novel therapeutic prodrugs with improved drug potency in future drug development.

A Neumaier graph is a non-complete edge-regular graph containing a regular clique. A Neumaier graph that is not strongly regular is called a strictly Neumaier graph. In this work we present a new construction of strictly Neumaier graphs, and using Jacobi sums, we show that our construction produces infinitely many instances. Moreover, we prove some necessary conditions for the existence of (strictly) Neumaier graphs that allow us to show that several parameter sets are not admissible. Copyright © 2021, The Authors.

MSC Codes 35L81, 35L05, 35D30, 35A35We consider a tsunami wave equation with singular coefficients and prove that it has a very weak solution. Moreover, we show the uniqueness results and consistency theorem of the very weak solution with the classical one in some appropriate sense. Numerical experiments are done for the families of regularised problems in one- and two-dimensional cases. In particular, the appearance of a substantial second wave is observed, travelling in the opposite direction from the point/line of singularity. Its structure and strength are analysed numerically. In addition, for the two-dimensional tsunami wave equation, we develop GPU computing algorithms to reduce the computational cost. Copyright © 2020, The Authors. All rights reserved.

In this paper we consider the heat equation with strongly singular potentials and prove that it has a "very weak solution". Moreover, we show the uniqueness and consistency results in some appropriate sense. The cases of positive and negative potentials are studied. Numerical simulations are done: one suggests so-called "laser heating and cooling" effects depending on a sign of the potential. The latter is justified by the physical *** Codes 35D99, 35K67, 34A45 Copyright © 2020, The Authors. All rights reserved.

We consider a space-fractional wave equation with a singular mass term depending on the position and prove that it is very weak well-posed. The uniqueness is proved in some appropriate sense. Moreover, we prove the consistency of the very weak solution with classical solutions when they exist. In order to study the behaviour of the very weak solution near the singularities of the coefficient, some numerical experiments are conducted where the appearance of a wall effect for the singular masses of the strength of δ2 is *** Codes 35L81, 35L05, 35D30, 35A35 Copyright © 2020, The Authors.

A Neumaier graph is a non-complete edge-regular graph containing a regular clique. In this paper we give some sufficient and necessary conditions for a Neumaier graph to be strongly regular. Further we show that there does not exist Neumaier graphs with exactly four distinct eigenvalues. We also determine the Neumaier graphs with smallest eigenvalue −2. Copyright © 2020, The Authors.

In this paper the space-fractional Schrödinger equations with singular potentials are studied. Delta like or even higher-order singularities are allowed. By using the regularising techniques, we introduce a family of'weakened' solutions, calling them very weak solutions. The existence, uniqueness and consistency results are proved in an appropriate sense. Numerical simulations are done, and a particles accumulating effect is observed in the singular cases. From the mathematical point of view a "splitting of the strong singularity" phenomena is also *** Codes 35A21, 35D99, 35R11 Copyright © 2020, The Authors. All rights reserved.
