Preservers for the p-Norm of Linear Combinations of Positive Operators
Abstract and Applied Analysis, 2014 We describe the structure of those transformations on certain sets of positive operators which preserve the p-norm of linear combinations with given nonzero real coefficients. These sets are the collection of all positive pth Schatten-class operators and

Property Preservation and Act Preservation
, 2023 AbstractIn China, some defendants will, upon becoming aware of being sued, take various methods to transfer and/or hide their property or the subject matter in dispute. In such circumstances, even if the plaintiff wins the case, it may still find it difficult to be actually compensated.

FEBS Letters, EarlyView.Biomolecular condensates formed by fused in sarcoma (FUS) are dissolved by high ATP concentrations yet persist in cells. Using a reconstituted system, we demonstrate that valosin‐containing protein (VCP), an AAA+ ATPase, counteracts ATP‐driven dissolution of FUS condensates through its D2 ATPase activity.

Abstract and Applied Analysis, 2013 We will give the -Lipschitz version of the Banach-Stone type theorems for lattice-valued -Lipschitz functions on some metric spaces. In particular, when and are bounded metric spaces, if is a nonvanishing preserver, then is a weighted composition ...

Diversity and complexity in neural organoids
FEBS Letters, EarlyView.Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

The linear preservers of real diagonalizable matrices [PDF]
, 2011 Using a recent result of Bogdanov and Guterman on the linear preservers of pairs of simultaneously diagonalizable matrices, we determine all the automorphisms of the vector space Mn(R) which stabilize the set of diagonalizable matrices.

On positivity preservers with constant coefficients and their generators [PDF]
In this work we study positivity preservers T : R[x1, ..., xn] → R[x1, ..., xn] with constant coefficients and define their generators A if they exist, i.e., exp(A) = T. We use the theory of regular Fréchet Lie groups to show the first main result.

Museum presentation and new trends in exhibition displays from a museological perspective using the example of selected European university museums and collections [PDF]
Muzeológia a Kultúrne DedičstvoAgainst the background of museological theory, this paper questions new trends in current museum exhibition displays, focusing on universities as institutions of higher education and as preservers of cultural heritage.

Preservation of Nitrosomonas [PDF]
Nature, 1957 IT is well known that the isolation of Nitrosomonas in pure culture is rather difficult; another problem is how the pure cultures can be successfully preserved. Nitrosomonas seems to be more frail than most other bacteria when in pure culture, and unfortunately the majority of strains isolated during past years have been lost.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.
