Affine Anosov Diffeomorphims of Affine Manifolds
We show that a compact affine manifold endowed with an affine Anosov transformation is finitely covered by a complete affine nilmanifold. This is a partial answer of a conjecture of Franks for affine manifolds.

Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Siegfried Kracauer’s affinities
Seen from today’s vantage point, Siegfried Kracauer’s Theory of Film (1960) envisages the possibility that the cinema may turn out to have been a historical phenomenon whose technological specifications as well as aesthetic properties are contingent, but

High affinity antibodies to Plasmodium falciparum merozoite antigens are associated with protection from malaria. [PDF]
BACKGROUND: Malaria kills almost 1 million people every year, but the mechanisms behind protective immunity against the disease are still largely unknown.

Let \({\mathbf P \mathbf G}(V)\) be an \((n + 1)\)-dimensional projective space arising from a right \((n + 2)\)-dimensional vector space over some skewfield \(D\). Let \(0 \leq k \leq n\) and let \({\mathcal H}\) be a collection of \(k\)-dimensional subspaces of \({\mathbf P \mathbf G} (V)\) with the property that for every \((k-1)\)-dimensional ...

We study the properties of affine rigidity of a hypergraph and prove a variety of fundamental results. First, we show that affine rigidity is a generic property (i.e., depends only on the hypergraph, not the particular embedding). Then we prove that a graph is generically neighborhood affinely rigid in d-dimensional space if it is (d+1)-vertex ...

We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

We propose a marriage model where assortative matching results in equilibrium for reasons other than those driving similar results in the search and matching literature. A marriage is a joint venture where husband and wife contribute to the couple’s welfare by allocating their time to portfolios of risky activities.
