Analytical Expression of the Beam-Plasma Particles Distribution Function Effect on the Electromagnetic Instability Growth Rate in Strongly Coupled Plasmas [PDF]

Iranian Journal of Astronomy and Astrophysics
The beam-plasma particles distribution function is one of the parameters which plays an important role in the energy-traveling mechanism of the relativistic electrons generated by the laser-plasma interaction in the Inertial Confinement Fusion Plasma ...

How the Carrier Mobility and Seebeck Coefficient of Doped Semiconducting Polymers Are Controlled by Counterion Interactions and Mesoscale Order

Advanced Functional Materials, EarlyView.
Conventional doping of P3HT with F4TCNQ results in poor charge transport. However, when F4TCNQ is exchanged with LiTFSI, the transport characteristics are greatly enhanced. We find the increase in charge transport is directly related to an increase in the mesoscale ordering of P3HT, resulting in longer and better‐connected transport pathways.

Electron Kappa Distributions in Astrophysical Nebulae

, 2017
Until recently, it had been assumed that the electrons in astrophysical nebulae (HII regions and planetary nebulae) are in thermal equilibrium, with energies described by the Maxwell–Boltzmann distribution. This may not always be true. Based on satellite and space probe measurements of electron energies in the solar system, where nonequilibrium energy ...

Solution‐Processed Two‐Dimensional Indium Oxide on Sodium‐Embedded Alumina for Reconfigurable Optoelectronic Synaptic Transistors

Advanced Functional Materials, EarlyView.
Wafer‐scale two‐dimensioanl In2Se3 oxidized into InOx on sodium‐embedded beta‐alumina enables multifunctional reconfigurable electronics. Sodium ions accumulate within distinct spatial distribution under drain‐controlle and gate‐controlled operation. Drain‐control operation gives controllability of ultraviolet‐driven optoelectronic synaptic conductance

Harriss Generalized Kappa Distribution: Statistical Modeling and Practical Applications in Finance and Engineering

Engineering Reports
This study presents a four‐parameter distribution which is called the Harris generalized Kappa distribution, which is flexible and tractable. The new distribution extends the two‐parameter Kappa distribution, and it can be explored to model highly skewed

Prior Specification and Bayesian Inference for Kappa

, 2007
Cohen's Kappa 是一個被廣泛應用的一致性量測。本文主要探討如何利用貝氏統計方法來估計兩位判讀者之間的一致性程度，此時假設資料為二元分類判讀結果，並假設兩位判讀者判讀為正的機率相同。本文提出兩種Jeffreys' prior來估計kappa，其一為階層式先驗分配 (hierarchical prior)，引進efficient Fisher information概念，求出kappa的條件先驗分配，再配合邊際機率先驗分配的選取來求出kappa眾數估計值 ...

Machine Learning‐Assisted Inverse Design of Soft and Multifunctional Hybrid Liquid Metal Composites

Advanced Functional Materials, EarlyView.
A machine learning framework is presented for inverse design of synthesizable multifunctional composites containing both liquid metal and solid inclusions. By integrating physics‐based modeling, data‐driven prediction, and Bayesian optimization, the approach enables intelligent design of experiments to identify optimal compositions and realize these ...
