FEBS Letters, EarlyView.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

The role and implications of mammalian cellular circadian entrainment
FEBS Letters, EarlyView.At their most fundamental level, mammalian circadian rhythms occur inside every individual cell. To tell the correct time, cells must align (or ‘entrain’) their circadian rhythm to the external environment. In this review, we highlight how cells entrain to the major circadian cues of light, feeding and temperature, and the implications this has for our

Bounded-confidence model of opinion dynamics with heterogeneous node-activity levels
Physical Review Research, 2023 Agent-based models of opinion dynamics allow one to examine the spread of opinions between entities and to study phenomena such as consensus, polarization, and fragmentation.

The newfound relationship between extrachromosomal DNAs and excised signal circles
FEBS Letters, EarlyView.Extrachromosomal DNAs (ecDNAs) contribute to the progression of many human cancers. In addition, circular DNA by‐products of V(D)J recombination, excised signal circles (ESCs), have roles in cancer progression but have largely been overlooked. In this Review, we explore the roles of ecDNAs and ESCs in cancer development, and highlight why these ...

Study of the heterogenous crystallization of polypropylene with various coupling agents
Revista Técnica de la Facultad de Ingeniería, 2010 In this work the nucleating effect on the crystallization of polypropylene (PP) of certain pigments of common use, like phtalocianine and quinacridone treated or not with various coupling agents, has been studied and compared with that of talc and ...

Learning to Learn: A Case for the Heterogeneous Expectations Hypothesis in Industrialized Markets
International Journal on Food System Dynamics, 2016 A cobweb model is developed where the heterogeneous expectation hypothesis is examined. An agent’s heterogeneous expectation involves the development of a “higher ordered learning” process in which agents over time develop expectations that are ...

Coalition stability with heterogeneous agents [PDF]
Economics Bulletin, 2011 We analyze coalition formation with heterogeneous agents based on an individual stability concept. Defining exchanging and refractory agents, we give existence and enlargement conditions for coalitions with heterogeneous agents. Using the concept of exchanging agents we give necessary conditions for internal stability and show that refraction is a ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Adverse Selection with Heterogeneously Informed Agents [PDF]
SSRN Electronic Journal, 2017 AbstractA model of over‐the‐counter markets is proposed. Some asset buyers are informed in that they can identify high‐quality assets. Sellers with private information choose what type of buyers they want to trade with. When the measure of informed buyers is low, a unique equilibrium exists, and interestingly, price, trading volume and welfare ...
