High‐Efficiency Deep Blue Single‐Gaussian Europium(II) Emitters and Their Emitter‐Host Interactions
Advanced Functional Materials, EarlyView.Crown‐ether ligands and carborate anions enable vacuum‐processable Eu(II) emitters with efficient single‐Gaussian deep‐blue luminescence. Combined photophysical and computational analyses reveal that excited‐electron confinement and steric shielding of the europium center jointly govern compatibility with OLED host materials, establishing molecular ...

Advanced Functional Materials, EarlyView.Establishment of bidirectional communication behavior between natural and artificial cells. The first type of communication from natural dendritic cells to artificial polymeric cells was achieved via ATP release after cell lysis. The released ATP was taken up via gated UV‐controlled permeability increase of the polymeric membrane for performing ...

Breaking the symmetry to structure light
Optics Letters, 2021We show that by breaking the symmetry of a beam subjected to tight focusing, namely by obscuring half of it or, equivalently, shifting the beam away from the lens axis, it is possible to obtain novel light properties in the focal spot which, to the best of our knowledge, have not been observed before.

Testing for Structural Breaks [PDF]
, 1991 The purpose of this paper is to investigate the tests of Hansen (1991) to detect structural breaks in cointegrated relations using Monte Carlo methods. The evaluation takes place within the linear quadratic model. The evidence for a single regressor suggests that the test have proper size and that the power is good provided the cost of adjustment is ...

Journal of Sports Economics, 2015
To search for eras in a sports league, we utilize time-series tests with structural breaks in Major League Baseball performance. Using data from 1871-2010, the mean and standard deviation of four different performance measures are examined. Throughout, rather than assume that a break point is known a priori, we identify breaks endogenously from the ...

Testing the Null of Cointegration with Structural Breaks* [PDF]
Oxford Bulletin of Economics and Statistics, 2006 AbstractWe propose a Lagrange Multiplier‐type statistic to test the null hypothesis of cointegration allowing for the possibility of a structural break, in both the deterministic and the cointegration vectors. Our proposal focuses on the presence of endogenous regressors.

Breaking the chains: structure and function of the deubiquitinases
Nature Reviews Molecular Cell Biology, 2009Ubiquitylation is a reversible protein modification that is implicated in many cellular functions. Recently, much progress has been made in the characterization of a superfamily of isopeptidases that remove ubiquitin: the deubiquitinases (DUBs; also known as deubiquitylating or deubiquitinating enzymes). Far from being uniform in structure and function,

Breaking abstractions and unstructuring data structures
Proceedings of the 1998 International Conference on Computer Languages (Cat. No.98CB36225), 2002To ensure platform independence, mobile programs are distributed in forms that are isomorphic to the original source code. Such codes are easy to decompile, and hence they increase the risk of malicious reverse engineering attacks. Code obfuscation is one of several techniques which has been proposed to alleviate this situation. An obfuscator is a tool
