Bayesian Inference for Median of the Lognormal Distribution [PDF]
, 2016 Lognormal distribution has many applications. The past research papers concentrated on the estimation of the mean of this distribution. This paper develops credible interval for the median of the lognormal distribution. The estimated coverage probability

On the Tails of the Distribution of the Sum of Lognormals [PDF]
2007 IEEE International Conference on Communications, 2007 Finding the distribution of the sum of lognormal random variables is an important mathematical problem in wireless communications, as well as in many other fields. While several methods exist to approximate this distribution, their performance tends to deteriorate in both tails. Finding a good overall fit remains an open problem. Other disadvantages of

Journal of Telecommunications and Information Technology, 2016 The realistic wireless channels face combined (time shared) Nakagami-lognormal shadowing and unshadowing fading because of time varying nature of radio channel and mobile user.

Advanced Materials Technologies, EarlyView.Electric‐field‐assisted spin coating is introduced as a wet‐film processing route for guiding perovskite crystallization. A transient perpendicular field produces distinct structural maxima rather than monotonic grain growth: largest scanning electron microscopy (SEM)‐derived grain size at nominal 2 kV cm−1${\rm cm}^{-1}$, largest X‐ray diffraction ...

A Reconfigurable Memristive Spiking Neuron Enabling Advanced Neuromorphic Computing
Advanced Science, EarlyView.Pek Jun Tiw and co‐workers develop a reconfigurable memristive neuron that can exhibit four spiking behaviors with freely tunable spike train parameters. The neuron supports multiplexed spike encoding of multiple pieces of information. It also supports advanced neural network strategies, such as neural heterogeneity and dynamic mode switching ...

Two-Piece Multivariate lognormal distribution [PDF]
, 2014 We have extended the univariate bilognormal distribution to two piece multivariate lognormal distribution. The density function of two piece multivariate lognormal distribution is given and the maximum likelihood estimates of the parameters when the ...

A new subgrid-scale representation of hydrometeor fields using a multivariate PDF [PDF]
Geoscientific Model Development, 2016 The subgrid-scale representation of hydrometeor fields is important for calculating microphysical process rates. In order to represent subgrid-scale variability, the Cloud Layers Unified By Binormals (CLUBB) parameterization uses a multivariate ...

Advanced Science, EarlyView.Two‐photon calcium imaging in behaving 5xFAD mice reveals early CA1 coding deficits before behavioral decline. Task‐related place cell activity and splitter cell trajectory coding are impaired, with reduced retrospective dominance and greater prospective weighting.

Fitting the Modified-Power-Lognormal to the Sum of Independent Lognormals Distribution [PDF]
GLOBECOM 2009 - 2009 IEEE Global Telecommunications Conference, 2009 We propose a new method for calculating a tight approximation to the distribution of the sum of independent lognormal random variables. We make use of a three-parameter modified-power-lognormal distribution function as the approximating distribution.

Advanced Science, EarlyView.Microgels enable independent control of stiffness and interstitial space, overcoming limitations of conventional 3D hydrogels. Using fragmented gelatin methacryloyl microgels, we show that stiffness does not restrict non‐metastatic breast cancer growth, contrary to bulk hydrogels, and reveal the role of adherent‐to‐suspension transition in cancer ...
