Criteria for the Nonexistence of Kneser Solutions of DDEs and Their Applications in Oscillation Theory [PDF]
Applied Sciences, 2021 The objective of this study was to improve existing oscillation criteria for delay differential equations (DDEs) of the fourth order by establishing new criteria for the nonexistence of so-called Kneser solutions. The new criteria are characterized by taking into account the effect of delay argument.

The Transcription Factor SOX18 Inhibitor Small Molecule 4 Is a Potential Treatment of Cancer-Induced Lymphatic Metastasis and Lymphangiosarcoma. [PDF]
Cancer Rep (Hoboken)ABSTRACT Background Malignant tumors release growth factors, promoting lymphangiogenesis in primary tumors and draining sentinel lymph nodes, ultimately facilitating lymph node metastasis. As a malignant lymphatic tumor entity, lymphangiosarcomas are characterized by low survival rates and limited treatment options. The transcription factor SOX18 plays

New Results for Kneser Solutions of Third-Order Nonlinear Neutral Differential Equations [PDF]
Mathematics, 2020 In this paper, we consider a certain class of third-order nonlinear delay differential equations r w ″ α ′ v + q v x β ς v = 0 , for v ≥ v 0 , where w v = x v + p v x ϑ v . We obtain new criteria for oscillation of all solutions of this nonlinear equation.

On Conservative Averaging Method in Spline Applications
Современные информационные технологии и IT-образование, 2020 We consider the conservative averaging method for solving the 3-D boundary-value problem of second order in multilayer domain. Looking back to the history of mathematics, integral parabolic splines relates to conservative averaging method (CAM ...

Prodsimplicial-Neighborly Polytopes [PDF]
, 2009 Simultaneously generalizing both neighborly and neighborly cubical polytopes, we introduce PSN polytopes: their k-skeleton is combinatorially equivalent to that of a product of r simplices.

Nonexistence of Kneser solution for third order nonlinear neutral delay differential equations
Journal of Physics: Conference Series, 2021 Abstract The achieved sufficient conditions for nonexistence of so-called Kneser solutions are based on the new comparison principles, which help us decrease the problem of the wavering between the third and first-order equations. Examples are given to prove the significance of new theorems.

Handling Massive N-Gram Datasets Efficiently [PDF]
, 2018 This paper deals with the two fundamental problems concerning the handling of large n-gram language models: indexing, that is compressing the n-gram strings and associated satellite data without compromising their retrieval speed; and estimation, that is

Nonoscillatory solutions of the four-dimensional difference system
Electronic Journal of Qualitative Theory of Differential Equations, 2012 We study asymptotic properties of nonoscillatory solutions for a four-dimensional system \[\begin{aligned} \Delta x_{n}&= C_{n}\, y_{n}^{\frac{1}{\gamma}} \\ \Delta y_{n}&= B_{n}\, z_{n}^{\frac{1}{\beta}} \\ \Delta z_{n}&= A_{n}\, w_{n}^{\frac{1}{\alpha}}

Extensions of Fractional Precolorings show Discontinuous Behavior [PDF]
, 2012 We study the following problem: given a real number k and integer d, what is the smallest epsilon such that any fractional (k+epsilon)-precoloring of vertices at pairwise distances at least d of a fractionally k-colorable graph can be extended to a ...

On Kneser Solutions of Nonlinear Third Order Differential Equations
Journal of Mathematical Analysis and Applications, 2001 The paper concerns the third-order differential equation \(y'''(t)+q(t)y'(t)+f(y(t))=0\) on \([0,+\infty)\). Existence and asymptotic behaviour of Kneser solutions \(y\) are investigated, which are either positive, decreasing, and convex, or negative, increasing, and concave on some \([t_y,+\infty)\).
