Direct Numerical Simulation of Tollmien Schlichting Waves to Support Linear Stability Analysis

, 2013
In the present study direct numerical simulations (DNS) of Tollmien-Schlichting waves in attached boundary layers will be shown in comparison with local linear stability theory (LST).

Squares of Random Linear Codes [PDF]

IEEE Transactions on Information Theory, 2015
Given a linear code $C$, one can define the $d$-th power of $C$ as the span of all componentwise products of $d$ elements of $C$. A power of $C$ may quickly fill the whole space. Our purpose is to answer the following question: does the square of a code "typically" fill the whole space?

Tau acetylation at K331 has limited impact on tau pathology in vivo

FEBS Letters, EarlyView.
We mapped tau post‐translational modifications in humanized MAPT knock‐in mice and in amyloid‐bearing double knock‐in mice. Acetylation within the repeat domain, particularly around K331, showed modest increases under amyloid pathology. To test functional relevance, we generated MAPTK331Q knock‐in mice.

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.

Ternary Linear Codes and Quadrics [PDF]

The Electronic Journal of Combinatorics, 2009
For an $[n,k,d]_3$ code ${\cal C}$ with $gcd(d,3)=1$, we define a map $w_G$ from $\Sigma={\rm PG}(k-1,3)$ to the set of weights of codewords of ${\cal C}$ through a generator matrix $G$. A $t$-flat $\Pi$ in $\Sigma$ is called an $(i,j)_t$ flat if $(i,j)=(|\Pi \cap F_0|,|\Pi \cap F_1|)$, where $F_0 = \{P \in \Sigma | w_G(P) \equiv 0 \pmod{3 ...

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.

Valosin‐containing protein counteracts ATP‐driven dissolution of FUS condensates through its ATPase activity in vitro

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.

Constructions of some secret sharing schemes based on linear codes [PDF]

Известия Саратовского университета. Новая серия: Математика. Механика. Информатика
There are perfect and ideal threshold secret sharing schemes, for example, Shamir’s secret sharing  scheme. For the case of general secret sharing schemes with an arbitrary access structure, it is possible to construct a perfect scheme for any

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.
