On the Effect of Creep on Local Lattice Orientation in Single‐Crystal Ni‐Based Superalloy Microstructures

open access: yesAdvanced Engineering Materials, EarlyView.
During creep of a single‐crystal Ni‐based superalloy, the overall crystal orientation is observed to remain constant while the microstructure evolves. Despite the lack of macroscopic rotation, small (<1°) rotations are observed on the submicron size scale and are accommodated by counteracting rotations over the scale of several micrometers.

Upscaling Pulsed Laser Fragmentation in Liquids by Advanced Free‐Flow Setups

open access: yesAdvanced Materials Technologies, EarlyView.
Advanced flow setups providing thin colloid films are introduced to upscale pulsed laser fragmentation in liquids for sustainable nanoparticle synthesis. Their potential is demonstrated by yielding remarkably small ZnO nanoparticles of <7 nm. Numerical simulations complement the study, revealing that the superior performance can be attributed to ...

A new subgrid-scale representation of hydrometeor fields using a multivariate PDF [PDF]

open access: yesGeoscientific 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 ...

Stirring‐Induced Modulation of NIR Emission in Tm3+‐Doped Nanoparticles: Evidence of Apparent Risetime Sensitivity

open access: yesAdvanced Optical Materials, EarlyView.
Motion was found to induce significant variation in the luminescence intensity ratio of NIR‐emitting Tm3+‐doped NaYbF4 nanoparticles, which has been ascribed to the population dynamics of the Tm3+ ion's excited states. These findings provide the groundwork for the design of motion nanosensors that can operate in environments not accessible with UV–vis ...

Dynamic Regulation of Endogenous Transcription Factor Hubs at Single‐Molecule Resolution

open access: yesAdvanced Science, EarlyView.
This study combines single‐molecule microscopy and genome editing to characterize the dynamic behaviors of endogenous oncofusion transcription factor EWS::FLI1 in Ewing sarcoma cells. EWS::FLI1 forms neomorphic hubs that dynamically assemble and dissolve. The hubs are regulated during mitosis, by RNA, and by specific chemicals.

Quantitative laboratory results: normal or lognormal distribution?

open access: yesJournal of Laboratory Medicine, 2020
The identification of a suitable distribution model is a prerequisite for the parametric estimation of reference intervals and other statistical laboratory tasks. Classification of normal vs.

On the Discrimination between the Inverse Gaussian and Lognormal Distributions [PDF]

open access: yesالمجلة العراقية للعلوم الاحصائية, 2008
Both inverse Gaussian and lognormal distributions have been used among many well-known failure time distributions with positively skewed data. The problem of selecting between them is considered. The logarithm of maximum likelihood ratio has been used as

Fitting the Modified-Power-Lognormal to the Sum of Independent Lognormals Distribution [PDF]

open access: yesGLOBECOM 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.

A Reconfigurable Memristive Spiking Neuron Enabling Advanced Neuromorphic Computing

open access: yesAdvanced 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 ...

Space Jam‐Ming: Generating Interstitial Space Using Fragmented Granular GelMA to Investigate Novel Paradigms of Cancer Metastasis

open access: yesAdvanced 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 ...
