, 2006 We study the asymptotic behavior of piecewise constant least squares regression estimates, when the number of partitions of the estimate is penalized. We show that the estimator is consistent in the relevant metric if the signal is in $L^2([0,1])$, the ...

Advanced Functional Materials, EarlyView.The separation of Helium gas from natural gas is challenging but highly important. MIL‐116(Ga), a “non‐porous” metal–organic framework is used as a molecular sieve to separate He from CH4. Druse‐like MIL‐116(Ga) particles are integrated into polysulfone mixed matrix membranes.

Journal of Islamic Thought and Civilization, 2019 Income smoothing refers to the use of accounting techniques to level out net income fluctuations from one period to the next. Companies indulge in this practice to manipulate the earnings over the period in order to lower the level of uncertainty.

Advanced Functional Materials, EarlyView.This work explores Li‐substituted P2 layered oxides for Na‐ion batteries by crystallographic and electrochemical studies. The effect of lithium on superstructure orderings, on phase transitions during synthesis and electrochemical cycling and on the interplay of O‐ versus TM‐redox is revealed via various advanced techniques, including semi‐simultaneous

Optimal Divergence-Free Hatch Filter for GNSS Single-Frequency Measurement
Sensors, 2017 The Hatch filter is a code-smoothing technique that uses the variation of the carrier phase. It can effectively reduce the noise of a pseudo-range with a very simple filter construction, but it occasionally causes an ionosphere-induced error for low ...

Reconstruction of Cluster Masses using Particle Based Lensing I: Application to Weak Lensing
, 2008 We present Particle-Based Lensing (PBL), a new technique for gravitational lensing mass reconstructions of galaxy clusters. Traditionally, most methods have employed either a finite inversion or gridding to turn observational lensed galaxy ellipticities ...

On computing smooth solutions of problems with large lipschitz constants [PDF]
Applied Numerical Mathematics, 1986 This paper is concerned with the numerical integration of smooth solutions of ordinary differential equations assuming that they possess fast growing or decaying solutions. To study this problem the author considers as model problem a first order linear differential system with variable coefficients whose fundamental matrix has a dichotomy with slow ...

Advanced Functional Materials, EarlyView.This study presents novel anti‐counterfeiting tags with multilevel security features that utilize additional disguise features. They combine luminescent nanosized Ln‐MOFs with conductive polymers to multifunctional mixed‐matrix membranes and powder composites. The materials exhibit visible/NIR emission and matrix‐based conductivity even as black bodies.
