Mixtures, compounds and inflations of negative multinomial distribution
, 2017 The paper considers some relations between mixed, compound and inflated geometric and negative multinomial distributions. The dependence structure of multivariate random sums (compounds), discussed in this paper, is born to two factors, the equal number ...

α‐Synuclein Forms Distinct Micelle‐Like Assemblies at Low Ionic Strengths
Advanced Science, EarlyView.At high ionic strength, α‐synuclein forms diverse assemblies, including oligomers, fibrils, and condensates. Here, we show that at low ionic strength, α‐synuclein adopts a distinct, low‐abundance assembly state. These assemblies maintain a constant size above a critical concentration and do not coalesce, suggesting a micelle‐like organization ...

On the Exchangeable Multinomial Distribution [PDF]
, 2010 We derive an expression of the joint distribution of exchangeable multinomial random variables. In the literature this problem has mainly been addressed by the use of an extension of de Finetti\u27s theorem for binary data.

Advanced Science, EarlyView.Low latency carbon budget estimates for July 2024–June 2025 combine atmospheric CO2 growth rates, fossil emissions, ocean uptake, DGVM land fluxes, and OCO‐2 inversions. The budget shows that late‐2024 land carbon losses dominate the annual anomaly, while early‐2025 recovery differs between bottom‐up models and top‐down inversions, especially in ...

High‐Throughput Screening for Accelerated Oxide Glass Discovery
Advanced Science, EarlyView.A high‐throughput screening platform is presented that allows for accelerating laboratory glass synthesis by a factor of 102, using multicomponent stereolithographic printing. Automatic sample evaluation is achieved via Raman spectroscopy and similarity analysis without any sample preparation.

SOCIOECONOMIC INFLUENCES ON LAND USE CHOICE AT WATERSHED LEVEL: A MULTINOMIAL LOGIT ANALYSIS OF LAND USE DISTRIBUTION IN WEST GEORGIA [PDF]
Allocation of fixed proportion of land to developed, forest, agricultural and other land uses in a watershed was modeled as an optimization problem faced by a single user.

Advanced Electronic Materials, EarlyView.Physical reservoir computing (PRC) based on spin wave interference has demonstrated high computational performance, yet room for improvement remains. In this study, we fabricated this concept PRC with eight detectors and evaluated the impact of the number of detectors using a chaotic time series prediction task.

Advanced Electronic Materials, EarlyView.Passive resistive memory arrays promise efficient in‐memory computing but suffer from sneak paths and programming variability. Here, highly uniform 32 × 32 passive RRAM crossbars are programmed with multilevel precision below 3% error and 99.5% yield.

A Dual‐Branch Flux‐Based Extended Memristor Model With Machine‐Learning‐Assisted Calibration
Advanced Electronic Materials, EarlyView.Multilayer oxide memristors integrated in crossbar arrays are described through a dual‐branch, flux‐controlled compact model. A three‐stage calibration workflow combining Latin hypercube sampling, Bayesian optimization, and gradient‐based refinement extracts device parameters from experimental data.

This note shows a symbolic formula for the square-root-free Cholesky decomposition of the variance--covariance matrix of the negative multinomial distribution. A similar decomposition was given for the multinomial case by Tanabe and Sagae (1984).
