Open AccessSpectrum of severity of multisystem inflammatory syndrome in children: an EHR-based cohort study from the RECOVER program
Multi-system inflammatory syndrome in children (MIS-C) is a severe post-acute sequela of SARS-CoV-2 infection in children, and there is a critical need to unfold its highly heterogeneous disease patterns. Our ...

Open AccessPredict the compressive strength of ultra high-performance concrete by a hybrid method of machine learning
Ultra-high performance concrete (UHPC) benefits the construction industry due to its improved flexibility, high workability, durability, and performance compared to normal concrete. Some investigators have con...

Robust matrix estimations meet Frank–Wolfe algorithm
We consider estimating matrix-valued model parameters with a dedicated focus on their robustness. Our setting concerns large-scale structured data so that a regularization on the matrix’s rank becomes indispen...

Almost sure convergence of stochastic composite objective mirror descent for non-convex non-smooth optimization
Stochastic composite objective mirror descent (SCOMID) is an effective method for solving large-scale stochastic composite problems in machine learning. This method can efficiently use the geometric properties...

Truncated octree and its applications
Octree is a hierarchical data structure with many applications, especially in encoding unstructured point clouds. The depth of an octree is dependent of the scale of the input data and the desired resolution o...

Microstructure and wear behavior of Ti-6Al-4V treated by plasma Zr-alloying and plasma nitriding
A duplex treatment of plasma Zr-alloying and plasma nitriding was used to improve the tribological properties of Ti-6Al-4V. The microstructure of the Zr-N composite (alloyed) layer formed on Ti-6Al-4V and its ...

Open AccessScreening of efficient siRNA carriers in a library of surface-engineered dendrimers
Polymers are widely used as non-viral carriers for siRNA delivery, but concern has also arisen in their limited efficacy and inherent toxicity. Whilst many of previous efforts have been documented towards impr...

A generalized preconditioned HSS method for singular saddle point problems
Li et al. recently studied the generalized HSS (GHSS) method for solving singular linear systems (see Li et al., J. Comput. Appl. Math. 236, 2338–2353 (2012)). In this paper, we generalize the method and present ...

A note on preconditioned GMRES for solving singular linear systems
For solving a singular linear system Ax=b by GMRES, it is shown in the literature that if A is range-symmetric, then GMRES converges safely to a solution. In this paper we consider preconditioned GMRES for solvin...

A note on the perturbation of an outer inverse
In this note, we present an explicit formula for perturbations of an outer inverse under certain conditions, which extends previous results.

Quotient convergence and multi-splitting methods for solving singular linear equations
In this paper, we use the group inverse to characterize the quotient convergence of an iterative method for solving consistent singular linear systems, when the matrix index equals one. Next, we show that for ...
