recommendations! Published in 2017 at "Journal of Computational Chemistry"

DOI: 10.1002/jcc.24912

Abstract: We have implemented a linear‐scaling divide‐and‐conquer (DC)‐based higher‐order coupled‐cluster (CC) and Møller–Plesset perturbation theories (MPPT) as well as their combinations automatically by means of the tensor contraction engine, which is a computerized symbolic algebra system.… read more here.

DOI: 10.1007/s10878-020-00584-2

Abstract: We introduce and asses several Divide-and-Conquer heuristic strategies, aimed at solving large instances of the 0–1 Minimization Knapsack Problem. The method subdivides a large problem in two smaller ones (or recursive iterations of the same… read more here.

DOI: 10.1007/s11042-019-07802-y

Abstract: This paper proposes a divide-and-conquer fragile self-embedding watermarking with adaptive payload for digital images. A graph-based visual saliency (GBVS) model is adopted to automatically classify image blocks into region of interest (ROI) and background (ROB).… read more here.

recommendations! Published in 2019 at "Numerical Algorithms"

DOI: 10.1007/s11075-019-00776-w

Abstract: In this work, we consider two types of large-scale quadratic matrix equations: continuous-time algebraic Riccati equations, which play a central role in optimal and robust control, and unilateral quadratic matrix equations, which arise from stochastic… read more here.

DOI: 10.1007/s42519-019-0048-5

Abstract: The information-based optimal subdata selection (IBOSS) is a computationally efficient method to select informative data points from large data sets through processing full data by columns. However, when the volume of a data set is… read more here.

DOI: 10.1016/j.cplett.2018.09.056

Abstract: Abstract We have extended the divide-and-conquer (DC) coupled-cluster with singles and doubles (CCSD) to a fractional occupation number (FON) formalism, denoted as FON-DC-CCSD, using the thermal Wick theorem. The motivation is to address the inconsistency… read more here.

DOI: 10.1016/j.mri.2019.06.014

Abstract: Compressed sensing (CS) theory assures us that we can accurately reconstruct magnetic resonance images using fewer k-space measurements than the Nyquist sampling rate requires. In traditional CS-MRI inversion methods, the fact that the energy within… read more here.

DOI: 10.1016/j.tcb.2016.08.003

Abstract: Cell invasion through the basement membrane (BM) occurs during normal embryonic development and is a fundamental feature of cancer metastasis. The underlying cellular and genetic machinery required for invasion has been difficult to identify, due… read more here.

DOI: 10.1021/acs.chemmater.7b03138

Abstract: Chemical bonding, traditionally being the language of chemists, gives a wealth of intuitive shortcuts in understanding structure, properties, and reactivity of molecules. An analogous language based on structure or even just formula of materials would… read more here.

recommendations! Published in 2022 at "Journal of chemical theory and computation"

DOI: 10.1021/acs.jctc.2c00142

Abstract: Non-orthogonal localized molecular orbitals (NOLMOs) have been employed as building blocks for the divide-and-conquer (DC) linear scaling method. The NOLMOs are calculated from subsystems and used for constructing the density matrix (DM) of the entire… read more here.

DOI: 10.1042/bst20220014

Abstract: Mitochondria have long been appreciated as the metabolic hub of cells. Emerging evidence also posits these organelles as hubs for innate immune signalling and activation, particularly in macrophages. Macrophages are front-line cellular defenders against endogenous… read more here.
