points. The introduction of approximation to exact vanishing ideal has played a
critical role in capturing the nonlinear structures of noisy data by computing

Opportunities for Two-color Experiments at the SASE3 undulator line of the European XFEL | X-ray Free Electron Lasers (XFELs) have been proven to generate short and
powerful radiation pulses allowing for a wide class of novel experiments. If an
XFEL facility supports the generation of two X-ray pulses with different
wavelengths and controllable delay, the range of possible experiments is

Braiding errors in interacting Majorana quantum wires | Avenues of Majorana bound states (MBSs) have become one of the primary
directions towards a possible realization of topological quantum computation.
For a Y-junction of Kitaev quantum wires, we numerically investigate the

Machine Learning for Structured Clinical Data | Research is a tertiary priority in the EHR, where the priorities are patient
care and billing. Because of this, the data is not standardized or formatted in

Hidden order and symmetry protected topological states in quantum link ladders | We show that whereas spin-1/2 one-dimensional U(1) quantum-link models (QLMs)
are topologically trivial, when implemented in ladder-like lattices these
models may present an intriguing ground-state phase diagram, which includes a
symmetry protected topological (SPT) phase that may be readily revealed by
analyzing lon... | 0 | 1 | 0 | 0 | 0 | 0 |
The effect of prudence on the optimal allocation in possibilistic and mixed models | In this paper two portfolio choice models are studied: a purely possibilistic
model, in which the return of a risky asset is a fuzzy number, and a mixed
model in which a probabilistic background risk is added. For the two models an
approximate formula of the optimal allocation is computed, with respect to the

encryption, anonymi... | 1 | 0 | 0 | 0 | 0 | 0 |
Design and Analysis of a Secure Three Factor User Authentication Scheme Using Biometric and Smart Card | Password security can no longer provide enough security in the area of remote

Real-World Modeling of a Pathfinding Robot Using Robot Operating System (ROS) | This paper presents a practical approach towards implementing pathfinding
algorithms on real-world and low-cost non- commercial hardware platforms. While

Understanding Convolution for Semantic Segmentation | Recent advances in deep learning, especially deep convolutional neural

Mechanical Failure in Amorphous Solids: Scale Free Spinodal Criticality | The mechanical failure of amorphous media is a ubiquitous phenomenon from
material engineering to geology. It has been noticed for a long time that the
phenomenon is "scale-free", indicating some type of criticality. In spite of
attempts to invoke "Self-Organized Criticality", the physical origin of this
criticality,... | 0 | 1 | 0 | 0 | 0 | 0 |
Moment conditions in strong laws of large numbers for multiple sums and random measures | The validity of the strong law of large numbers for multiple sums $S_n$ of

On the Semantics and Complexity of Probabilistic Logic Programs | We examine the meaning and the complexity of probabilistic logic programs

Fitting Probabilistic Index Models on Large Datasets | Recently, Thas et al. (2012) introduced a new statistical model for the
