Extreme event statistics of daily rainfall: Dynamical systems approach

, 2016
We analyse the probability densities of daily rainfall amounts at a variety of locations on the Earth. The observed distributions of the amount of rainfall fit well to a q-exponential distribution with exponent q close to q=1.3.

Probing Cellular Activity Via Charge‐Sensitive Quantum Nanoprobes

Advanced Materials, EarlyView.
A new quantum sensing modality detects shifts in zero‐field splitting caused by charge rearrangement with diamond nanocrystals in response to cellular activity. These electric‐field‐driven effects provide an alternative to temperature‐based interpretations, enabling real‐time, single‐cell readout of inflammation.

PiP‐Plex: A Particle‐in‐Particle System for Multiplexed Quantification of Proteins Secreted by Single Cells

Advanced Materials, EarlyView.
Detecting proteins secreted by a single cell while retaining its viability remains challenging. A particles‐in‐particle (PiPs) system made by co‐encapsulating barcoded microparticles (BMPs) with a single cell inside an alginate hydrogel particle is introduced.

Local Energy Statistics in Directed Polymers

, 2007
Recently, Bauke and Mertens conjectured that the local statistics of energies in random spin systems with discrete spin space should, in most circumstances, be the same as in the random energy model.

Random transitions described by the stochastic Smoluchowski-Poisson system and by the stochastic Keller-Segel model

, 2014
We study random transitions between two metastable states that appear below a critical temperature in a one dimensional self-gravitating Brownian gas with a modified Poisson equation experiencing a second order phase transition from a homogeneous phase ...

Moth‐Wing‐Inspired Multifunctional Metamaterials

Advanced Materials, EarlyView.
This study develops a moth‐wing‐inspired heterogeneous metamaterial that achieves synergistic broadband sound absorption, mechanical energy dissipation, and thermal insulation within a lightweight architected framework. Combining bioinspired gradient design, genetic‐algorithm optimization, and additive manufacturing, the bionic heterogeneous acoustic ...

Hierarchical Compound Poisson Factorization

, 2016
Non-negative matrix factorization models based on a hierarchical Gamma-Poisson structure capture user and item behavior effectively in extremely sparse data sets, making them the ideal choice for collaborative filtering applications. Hierarchical Poisson
