Calibration of Flow Cytometers Enables Reproducible Measurements of Extracellular Vesicle Concentrations and Reference Range Establishment. [PDF]

J Extracell Vesicles
ABSTRACT The concentration of cells is a key component of modern blood tests. Given the biomarker potential of extracellular vesicles (EVs) in blood, we aimed to establish reference ranges for blood cell‐derived EVs using flow cytometry. To address the orders‐of‐magnitude variability in reported EV concentrations between different flow cytometers (FCMs)

Use of reproducing kernels and Berezin symbols technique in some questions of operator theory

Forum Mathematicum, 2012
We give in terms of Berezin symbols some characterizations for the operators belonging to the Schatten-von Neumann classes sigma(p), 0 < p < +infinity, which were motivated by the questions posed by Nordgren and Rosenthal [7]. Some other problems related with the multiplicative equality for Berezin symbols are also discussed.

Invertibility and Fredholm Property of Fock Toeplitz Operators

Mathematics, 2023
We characterize some necessary and sufficient conditions of invertible Toeplitz operators acting on the Fock space. In particular, we study the Fredholm properties of Toeplitz operators with BMO1 symbols, where their Berezin transforms are bounded ...

Some applications of Berezin θ-sequences and Berezin symbols

Filomat, 2021
We consider the so-called Berezin ?-sequence, where ? is an operator valued inner function, for operators on the vector valued Hardy space H2E (D), and study the invertibility of some operators on the model space K? = H2E ? ?H2E via Berezin ?-sequence. By applying of Berezin symbols technique the Toeplitz corona problem in the Bergman space

The nation in bronze and granite: Creating national monuments in post‐Soviet Bishkek

Nations and Nationalism, Volume 29, Issue 2, Page 648-668, April 2023., 2023
Abstract Scholars of nationalism have long looked to material forms of symbolic power to understand the politics and cultures of nations, and national monuments specifically have been studied as reflections of ideological programmes of political regimes. However, these approaches have paid insufficient attention to processes of creation.

Fredholm and Schatten Class Operators on Bergman Spaces with Exponential Weights

Journal of Function Spaces, Volume 2023, Issue 1, 2023., 2023
In this paper, we give a characterization of Fredholmness of the Toeplitz operators on the Bergman spaces Aφp with exponential weights in D when 0 < p < ∞. Also, we obtain the sufficient and necessary conditions which the Toeplitz and Hankel operators on Aφ2 belong to h‐Schatten class, where h is a continuous increasing convex function.

Mobilizing the Past in Revolutionary Times: Memory, Counter‐Memory, and Nostalgia During the Lebanese Uprising

Sociological Forum, Volume 37, Issue S1, Page 1387-1413, December 2022., 2022
Social movement studies have addressed the issue of nostalgia within two perspectives, focusing, respectively, on emotions and on memory. Our contribution looks at nostalgia in social movements by building upon the combination of these two streams in social movement studies.

Increasing the scope of the resazurin‐resorufin smart tracer system in hydrologic and biogeochemical sciences: The effects of storage duration and temperature on preservation

Limnology and Oceanography: Methods, Volume 20, Issue 11, Page 701-709, November 2022., 2022
Abstract The resazurin (raz)‐resorufin (rru) smart tracer system has led to significant advances in hydrologic and biogeochemical sciences but its application has been limited in scope and geography by the short duration that it has been assumed samples can be reliably stored before analysis.

Na+ homeostasis in Acinetobacter baumannii is facilitated via the activity of the Mrp antiporter

Environmental Microbiology, Volume 24, Issue 9, Page 4411-4424, September 2022., 2022
Summary The human opportunistic pathogen Acinetobacter baumannii is a global threat to healthcare institutions worldwide, since it developed very efficient strategies to evade host defence and to adapt to the different environmental conditions of the host. This work focused on the importance of Na+ homeostasis in A.

Boundedness and Compactness of Hankel Operators on Large Fock Space

Journal of Function Spaces, Volume 2022, Issue 1, 2022., 2022
We introduce the BMO spaces and use them to characterize complex‐valued functions f such that the big Hankel operators Hf and Hf¯ are both bounded or compact from a weighted large Fock space Fp(ϕ) into a weighted Lebesgue space Lp(ϕ) when 1 ≤ p < ∞.
