On the inclusion probabilities in some unequal probability sampling plans without replacement

, 2012
Comparison results are obtained for the inclusion probabilities in some unequal probability sampling plans without replacement. For either successive sampling or H\'{a}jek's rejective sampling, the larger the sample size, the more uniform the inclusion ...

Single‐Target Pairing System (StarPair) for Large‐Scale Interrogation of Cell–Cell Interactions

Advanced Science, EarlyView.
This work presents a single‐target pairing system, StarPair, enabling cell–cell interaction studies by target combination in droplets. StarPair offers superior pairing efficiencies over 95% and operation frequencies of 105 pairs per 9.5 h for two‐target pairing, allowing large‐scale interrogation of immune cell‐cancer cell interactions and precise ...

Partitioned trace distances

, 2010
New quantum distance is introduced as a half-sum of several singular values of difference between two density operators. This is, up to factor, the metric induced by so-called Ky Fan norm.

Majorization Inequalities via Peano's Representation of Hermite's Polynomial

International Journal of Analysis and Applications, 2018
The Peano’s representation of Hermite polynomial and new Green functions are used to construct the identities related to the generalization of majorization type inequalities in discrete as well as continuous case. Cˇebyˇsev functional is used to find the bounds for new generalized identities and to develop the Gr¨uss and Ostrowski type inequalities ...

Experimental Joint Estimation of Phase and Phase Diffusion Via Deterministic Bell Measurements

Advanced Science, EarlyView.
This work employs Bell measurement, a form of entangling measurement, to estimate both the phase and its fluctuations in an optical interferometer. By incorporating a novel quantum effect at the measurement stage, the proposed method achieves the ultimate precision limit and demonstrates the significant potential of entangling measurements in multi ...

G-majorization inequalities for linear maps

Linear Algebra and its Applications, 1999
The author gives a unified treatment of majorization inequalities for linear maps using group-induced cone orderings. Necessary and sufficient conditions are given for inequalities to hold involving a vector product related to the Hadamard product, and some classical inequalities are deduced in this way.

Neural Network‐Based Permittivity Engineering of Magnetic Absorbers for Customizable Microwave Absorption

Advanced Science, EarlyView.
A neural network‐enabled permittivity engineering paradigm is introduced, transcending traditional trial‐and‐error design. By decoupling electromagnetic parameters and screening a high‐throughput feature space, an ultrathin (1.0 mm) magnetic absorber is inversely designed, experimentally achieving a superior and customizable 5.1 GHz bandwidth and ...
