ON THE STABILIZATION OF THE LINEAR HYBRID SYSTEM STRUCTURE

open access: yesПроблемы анализа, 2014
The linear control hybrid system, consisting of a fi- nite set of subsystems (modes) having different dimensions, is considered. The moments of reset time are determined by some complementary function – evolutionary time.

Impact of Metastatic Patterns on Survival and Response to Therapy in Neuroblastoma

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background While the presence of metastases in neuroblastoma (NB) is a well‐established prognostic factor, the clinical significance of dissemination patterns and tumour burden and their impact on response and survival remains poorly understood.

A structure filter for the Eukaryotic Linear Motif Resource

open access: yesBMC Bioinformatics, 2009
Background Many proteins are highly modular, being assembled from globular domains and segments of natively disordered polypeptides. Linear motifs, short sequence modules functioning independently of protein tertiary structure, are most abundant in ...

Linear optimal design of a magnetic repulsion negative stiffness structure

open access: yesJournal of Low Frequency Noise, Vibration and Active Control, 2021
To reduce negative stiffness structure’s stiffness non-linearity, enhance its stability during entire working displacement range, and expand its allowable working displacement, the optimal design of negative stiffness structure based on magnetic ...

On combinatorial structures in linear codes

open access: yesCoRR, 2023
In this work we show that given a connectivity graph $G$ of a $[[n,k,d]]$ quantum code, there exists $\{K_i\}_i, K_i \subset G$, such that $\sum_i |K_i|\in Ω(k), \ |K_i| \in Ω(d)$, and the $K_i$'s are $\tildeΩ( \sqrt{{k}/{n}})$-expander. If the codes are classical we show instead that the $K_i$'s are $\tildeΩ\left({{k}/{n}}\right)$-expander.

Ovarian Sex Cord Stromal Tumors in Children and Adolescents—The European Standard Clinical Practice Recommendations

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT As part of the European Cooperative Study Group for Paediatric Rare Tumours initiative, we developed standard clinical practice guidelines for ovarian sex cord stromal tumors, based on comprehensive national and international cohort analyses, literature review, and a final expert consensus conference.

Transversal loss factor of an rf-focussing iris structure with rectangular holes [PDF]

open access: yes, 1992
By replacing the irises in an electron linac by a slit one gets a structure capable of focussing/defocussing an electron beam (rf-quadrupoles). Therefore one can think of a combination of rf- and conventional magnetic quadrupoles for transversal ...

Bad luck in quadratic improvement of the linear estimator in a special linear model [PDF]

open access: yes, 1998
summary:The paper concludes our investigations in looking for the locally best linear-quadratic estimators of mean value parameters and of the covariance matrix elements in a special structure of the linear model (2 variables case) where the dispersions ...

Irregularity in the structure of linear formations

open access: yesالاكاديمي
The research entitled (Irregularity in the Structure of Calligraphy ) deals with how to leave the fixed patterns to unfamiliar linear patterns that break the monotony of the organization and activate the dynamic directionality, thus bypassing the ...

Kernel Identification of Non-Linear Systems with General Structure

open access: yesAlgorithms, 2020
In the paper we deal with the problem of non-linear dynamic system identification in the presence of random noise. The class of considered systems is relatively general, in the sense that it is not limited to block-oriented structures such as Hammerstein
