On badly approximable numbers [PDF]
Motivated by a wonderful paper by Ngoc Ai Van Nguyen, Anthony Po\"els and Damien Roy, where a powerful method was introduced, we prove a criterion for a vector $\pmb{\alpha}\in \mathbb{R}^d$ to be a badly approximable vector. Moreover we construct certain examples which show that a more general version of our criterion is not valid.

Psychometric Evaluation of the Shared Care Instrument in a Sample of Home Health Care Family Dyads [PDF]
Researchers have studied negative effects of caregiving on a family caregiver; however, less is known about positive aspects of exchanging assistance for both members of a family caregiving dyad.

Deterministic Chaos in Quantum Field Theory
We discuss the necessity and demonstrate the validity of introduction the notion of deterministic chaos in quantum field theory. Brief review of the existing approaches to this problem is given. We compare proposed chaos criterion for quantum fields with

A Generalized Criterion for Signature Related Gröbner Basis Algorithms [PDF]
A generalized criterion for signature related algorithms to compute Gr\"obner basis is proposed in this paper. Signature related algorithms are a popular kind of algorithms for computing Gr\"obner basis, including the famous F5 algorithm, the extended F5 algorithm and the GVW algorithm.

Bouncing threads for infinitary and circular proofs [PDF]
We generalize the validity criterion for the infinitary proof system of the multiplicative additive linear logic with fixed points. Our criterion is designed to take into account axioms and cuts. We show that it is sound and enjoys the cut elimination property.

Tree Unitarity and Partial Wave Expansion in Noncommutative Quantum Field Theory [PDF]
The validity of the tree-unitarity criterion for scattering amplitudes on the noncommutative space-time is considered, as a condition that can be used to shed light on the problem of unitarity violation in noncommutative quantum field theories when time ...

Validity of semiclassical gravity in the stochastic gravity approach
In semiclassical gravity the back-reaction of the classical gravitational field interacting with quantum matter fields is described by the semiclassical Einstein equations.

Equation of state and coarse grained free energy for matrix models [PDF]
We investigate phase transitions in three dimensional scalar matrix models, with special emphasis on complex $2 \times 2$ matrices. The universal equation of state for weak first order phase transitions is computed.
