On orbits under ergodic measure-preserving transformations [PDF]
Transactions of the American Mathematical Society, 1965 Let \(I\) be the unit interval with Lebesgue measure and let \(T\) be a 1-1 measure-preserving ergodic transformation mapping \(I\) onto \(I\). Intuitively one feels that the orbit \(\{T^nx\}\) of a ``general'' point \(x\in I\) should somehow determine \(T\). This notion is made precise in this paper.

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Improving Human Action Recognition Through Cross-View Camera-Aware Augmentation
Mehran University Research Journal of Engineering and TechnologyHuman Action Recognition (HAR) is vital in surveillance, sports analysis, and Human–Computer Interaction (HCI). Publicly available benchmarks mostly suffer from limited sample sizes, class imbalance, occlusions, and viewpoint variability, which may ...

Erratum to "On Entropy and Generators of Measure-Preserving Transformations" [PDF]
Transactions of the American Mathematical Society, 1972 Lemma (4.2) of this paper that appeared in Trans. Amer. Math. Soc. 149 (1970), 453-464, was stated incorrectly. To obtain the correct statement replace p(A0) >p(A1) + 2p(A2) by p(A0)>2p(A1)+2p(A2). (Cf. [2]. The lemma follows from Zaslavskil's work by using the coding system 221, 211, and by leaving symbols other than 0, 1, 2 unchanged in the coding ...

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Reversible entanglement beyond quantum operations
Physical Review ResearchWe introduce a reversible theory of exact entanglement manipulation by establishing a necessary and sufficient condition for state transfer under trace-preserving transformations that completely preserve the positivity of partial transpose (PPT).

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.

FCDFusion: A fast, low color deviation method for fusing visible and infrared image pairs
Computational Visual MediaVisible and infrared image fusion (VIF) aims to combine information from visible and infrared images into a single fused image. Previous VIF methods usually employ a color space transformation to keep the hue and saturation from the original visible ...

Projective limits of measure preserving transformations on probability spaces [PDF]
, 1972 Using the method of algebraic models, it is proved first that the projective limit T of a projective system of measure preserving transformations Tα exists and is unique, modulo conjugacy, and then that if Tα are ergodic with discrete spectrum, or ...
