The Specification of Dynamic Discrete-Time Two-State Panel Data Models

open access: yesEconometrics, 2018
This paper compares two approaches to analyzing longitudinal discrete-time binary outcomes. Dynamic binary response models focus on state occupancy and typically specify low-order Markovian state dependence.

Boundary control problem for a hyperbolic equation loaded along one of its characteristics

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2022
This paper investigates the unique solvability of the boundary control problem for a one-dimensional wave equation loaded along one of its characteristic curves in terms of a regular solution.

Background error covariances for a BlendVar assimilation system

open access: yesTellus: Series A, Dynamic Meteorology and Oceanography, 2017
We propose a new climatological background error covariance matrix suitable for the so-called BlendVar scheme, which deals with a problem on how to best preserve large-scale information of the global coupling system in the high-resolution limited area ...

Effect of Water Head and Irrigation Interval on Cumulative and Lateral Infiltration in Furrow Irrigation [PDF]

open access: yesعلوم و مهندسی آبیاری, 2019
Infiltration is considered as one of the most important soil parameters in the design and evaluation of furrow irrigation systems. Water is infiltrated through the wetted perimeter when it reaches a given point in the furrow until it recedes.

Data transmission system with encryption by chaotic sequences

open access: yesTekhnologiya i Konstruirovanie v Elektronnoi Apparature, 2014
Protection of transferable information in the telecommunication systems is possible by its imposition of coding sequence on a plaintext. Encryption of pseudorandom sequences can be performed by using generation algorithms which are implemented on the ...

Improving Low Earth Orbit (LEO) Prediction with Accelerometer Data

open access: yesRemote Sensing, 2020
Low Earth Orbit (LEO) satellites have been widely used in scientific fields or commercial applications in recent decades. The demands of the real time scientific research or real time applications require real time precise LEO orbits.

A Mechanistic Theory of Development-Aging Continuity in Humans and Other Mammals

open access: yesCells, 2022
There is consensus among biogerontologists that aging occurs either as the result of a purposeful genome-based, evolved program or due to spontaneous, randomly occurring, maladaptive events.

Initial conditions for supersymmetric inflation [PDF]

open access: yesPhysical Review D, 1997
We perform a numerical investigation of the fields evolution in the supersymmetric inflationary model based on radiative corrections. Supergravity corrections are also included. We find that, out of all the examined initial data, only about 10% give an adequate amount of inflation and can be considered as ''natural''. Moreover, these successful initial
