NP-hardness of geometric set cover and hitting set with rectangles containing a common point

Madireddy, R.R.; Mudgal, A. (2018-11-12)

We prove that both set cover and hitting set problems with points and axis-parallel rectangles are -hard even when (i) all rectangles share a common point and there are only two types of rectangles and for some positive ...

Upconversion nanoparticles (UCNP) with unique multi-photon excitation photo-luminescence properties have been extensively explored as novel contrast agents for low-background biomedical imaging. There is an increasing interest ...
Accuracy and quality of micro-holes in vibration assisted micro-electro-discharge drilling of Inconel 718

Unune, D.R.; Nirala, C.K.; Mali, H.S. (2018-12-12)

Achieving micro-features on superalloy like Inconel 718, with dimensionally high accuracy, has never been easy using a conventional machining technique. Micro-electro-discharge drilling (mEDD) has emerged as one of the ...
Modeling memetics using edge diversity

Gupta, Y.; Iyengar, S.R.S.; Saxena, A.; Das, D. (2018-12-12)

The diffusion of an idea significantly differs from the diffusion of a disease because of the interplay of the complex sociological and behavioral factors in the former. Hence, the conventional epidemiological models fail ...
Gold conjugated carbon dots nano assembly: FRET paired fluorescence probe for cysteine recognition

Sidhu, J.S.; Singh, A.; Garg, N.; Kaur, N.; Singh, N. (2018-12-12)

The detection and discrimination of Cys amino acid from numerous other related biomolecules has great importance in clinical field for diagnosis of various diseases. Herein, to detect the Cys, we embedded the carbon dots ...

Supervised heterogeneous feature transfer via random forests

Sukhija, S.; Narayanan, C.K. (2018-12-20)

Transfer learning across heterogeneous feature spaces can, in general, be a very difficult problem in practice due to the heterogeneity of features and lack of correspondence between data points of different domains. In ...

A heuristic approach to estimate nodes’ closeness rank using the properties of real world networks

Saxena, A.; Gera, R.; Iyengar, S.R.S. (2019-01-02)

Centrality measures capture the intuitive notion of the importance of a node in a network. Importance of a node can be a very subjective term and is defined based on the context and the application. Closeness centrality ...
