Life‐Like Ferrous Oxide Microspheres from Kombucha

Advanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Where Precursor Loading Stops Making a Difference: Resolving an Operational Infiltration Limit for Nanoparticle Synthesis Using Dual Quantification of Reverse Micelle Nanoreactors

Advanced Materials Interfaces, EarlyView.
A dual characterization strategy combining nanomechanical and mass measurements resolves a common operational loading threshold in reverse micelle nanoreactors. This transferable framework provides a rational strategy for optimizing precursor loading and nanoparticle synthesis, across template‐mediated fabrication systems.

Interface Dynamics in Biomolecular Condensates by High‐Speed AFM

Advanced Materials Interfaces, EarlyView.
High‐speed atomic force microscopy provides nanoscale structural dynamics at the liquid interface of biomolecular condensates, key elements in several cellular pathways. By addressing the challenges of low surface tension and condensate‐induced instabilities, we achieve nanometer spatial and sub‐second temporal resolution, revealing structural ...

Antibody‐Precomplexed Hemagglutinin Constructs Multivalently Bind Sialylated Glycan Receptors with Variable Valencies

Advanced Materials Interfaces, EarlyView.
Hemagglutinin precomplexation with antibodies (Abs) results in broad valency distributions, though it increases the total avidity from mM to nM to high nM. The valency distribution and the orientation of multivalent HA‐Ab complexes determine the extent of binding to different types of assays, whether the receptors are displayed in 2D or 3D.

The beta exponential distribution

Reliability Engineering and System Safety, 2006
Abstract The exponential distribution is perhaps the most widely applied statistical distribution for problems in reliability. In this note, we introduce a generalization—referred to as the beta exponential distribution—generated from the logit of a beta random variable.

A Characterization of the Exponential Distribution

Calcutta Statistical Association Bulletin, 1994
In this note we prove that the exponential distribution is characterized by the property [Formula: see text] where Y is a future observation and x 1 , x 2 ,…, x n are identical and independently distributed ...

The gamma-exponentiated exponential distribution

Journal of Statistical Computation and Simulation, 2012
In this paper, we introduce a new distribution generated by gamma random variables. We show that this distribution includes as a special case the distribution of the lower record value from a sequence of i.i.d. random variables from a population with the exponentiated (generalized) exponential distribution.

THE LOMAX-EXPONENTIAL DISTRIBUTION

Far East Journal of Theoretical Statistics, 2015
Summary: The exponential distribution is perhaps the most commonly used statistical distribution in reliability and the Lomax distribution is extensively studied with reference to order statistics. In this paper, we introduce a new statistical distribution constructed by combining the cumulative density function (cdf) of these two distributions and ...
