The homogeneous shifts

open access: yesJournal of Functional Analysis, 2003
AbstractA bounded linear operator T on a complex Hilbert space is called homogeneous if the spectrum of T is contained in the closed unit disc and all bi-holomorphic automorphisms of this disc lift to automorphisms of the operator modulo unitary equivalence. We prove that all the irreducible homogeneous operators are block shifts. Therefore, as a first

Development of 4T1 breast cancer mouse model system for preclinical carbonic anhydrase IX studies

open access: yesFEBS Open Bio, EarlyView.
Carbonic anhydrase IX (CAIX) is a well‐recognised therapeutic target and prognostic biomarker in cancer. We developed and characterised a robust murine breast cancer model system that is suitable for CAIX studies in vitro and in vivo—it comprises both CAIX‐positive and CAIX‐negative controls and provides a solid platform for the comprehensive ...

Universal homogeneous causal sets

open access: yes, 2005
Causal sets are particular partially ordered sets which have been proposed as a basic model for discrete space-time in quantum gravity. We show that the class C of all countable past-finite causal sets contains a unique causal set (U,

Distributed energy efficient unequal clustering algorithm for wireless sensor networks

open access: yesTongxin xuebao, 2009
A distributed energy-efficient unequal clustering (DEEUC) algorithm was proposed for wireless sensor net-works by research current routing algorithms. The core of DEEUC has three parts. Firstly, when tentative clusterheads are selected, an average energy

An efficient strategy for producing RNA‐free Nucleocapsid protein of SARS‐CoV‐2 for biochemical and structural investigations

open access: yesFEBS Open Bio, EarlyView.
Cleavable N‐terminal Thioredoxin fusion enabled soluble expression and purification of otherwise insoluble SARS‐CoV‐2 Nucleocapsid (N) protein. A four‐step purification strategy yielded highly homogeneous, RNA‐free N protein. Binding assays showed high RNA affinity (Kd ~ 28 nm). The study will facilitate high‐resolution structural studies of N protein,

Scientific bases of elementary physics courseon the example of the part «Conservation laws in mechanics»

open access: yesҚарағанды университетінің хабаршысы. Физика сериясы, 2017
The article is devoted to the conservation laws in mechanics. In this paper, an overview of the 3 fundamental physical laws, which are important in physics is quite huge. Conservation laws hold of all the laws of nature a special position.

The homogeneity conjecture [PDF]

open access: yesProceedings of the National Academy of Sciences, 1979
We show that, for any function f in which Kleene's O is computable, the ordering of Turning degrees (i.e., degrees of difficulty of computation of functions) is not isomorphic to the ordering of degrees of functions from which f is computable. This refutes a well-known

Genetic diversity and population structure of the Taigan dog breed

open access: yesFEBS Open Bio, EarlyView.
The Taigan is a rare sighthound from the mountains of Kyrgyzstan. We used DNA markers to study its genetic diversity and compare it with other sighthound breeds. Our findings show that the Taigan shares close genetic ties with the Kazakh Tazy, suggesting a common ancestry shaped by nomadic traditions and regional adaptation.

Characterization of ribosome heterogeneity during endothelial to hematopoietic transition

open access: yesFEBS Open Bio, EarlyView.
The panorama of ribosome heterogeneity during embryonic hematopoiesis has not yet been portrayed. In this study, utilizing dual‐omics data, the heterogenous dynamic of ribosome during endothelial‐to‐hematopoietic transition has been systemically described. Moreover, stage‐specific upregulation and peripheral localization of RPL27 and RACK1 in hemogenic
