The growth rates of automaton groups generated by reset automata | We give sufficient conditions for when groups generated by automata in a
class $\mathcal{C}$ of transducers, which contains the class of reset automata
transducers, have infinite order. As a consequence we also demonstrate that if
a group generated by an automata in $\mathcal{C}$ is infinite, then it contains
a free ... | 0 | 0 | 1 | 0 | 0 | 0 |
Combinatorial identities and Chern numbers of complex flag manifolds | We present in this article a family of new combinatorial identities via

Impact splash chondrule formation during planetesimal recycling | Chondrules are the dominant bulk silicate constituent of chondritic
meteorites and originate from highly energetic, local processes during the

and textural features, ... | 0 | 1 | 0 | 0 | 0 | 0 |
Z-checker: A Framework for Assessing Lossy Compression of Scientific Data | Because of vast volume of data being produced by today's scientific
simulations and experiments, lossy data compressor allowing user-controlled

Combining the Transcorrelated method with Full Configuration Interaction Quantum Monte Carlo: application to the homogeneous electron gas | We suggest an efficient method to resolve electronic cusps in electronic
structure calculations by using an effective transcorrelated Hamiltonian. This
effective Hamiltonian takes a simple form for plane wave bases, containing up

computational overhe... | 0 | 1 | 0 | 0 | 0 | 0 |
Dynamics of quantum information in many-body localized systems | We characterize the information dynamics of strongly disordered systems using
a combination of analytics, exact diagonalization, and matrix product operator
simulations. More specifically, we study the spreading of quantum information

Correlations in suspensions confined between viscoelastic surfaces: Noncontact microrheology | We study theoretically the velocity cross-correlations of a viscous fluid
confined in a slit between two viscoelastic media. We analyze the effect of

correlation, decaying... | 0 | 1 | 0 | 0 | 0 | 0 |
The Cosmic V-Web | The network of filaments with embedded clusters surrounding voids seen in

Irreducibility and r-th root finding over finite fields | Constructing $r$-th nonresidue over a finite field is a fundamental
computational problem. A related problem is to construct an irreducible

Competing magnetic interactions in spin-1/2 square lattice: hidden order in Sr$_2$VO$_4$ | With decreasing temperature Sr$_2$VO$_4$ undergoes two structural phase
transitions, tetragonal-to-orthorhombic-to-tetragonal, without long-range
magnetic order. Recent experiments suggest, that only at very low temperature
Sr$_{2}$VO$_{4}$ might enter some, yet unknown, phase with long-range magnetic
order, but with... | 0 | 1 | 0 | 0 | 0 | 0 |
Adaptive Matching for Expert Systems with Uncertain Task Types | A matching in a two-sided market often incurs an externality: a matched
resource may become unavailable to the other side of the market, at least for a
while. This is especially an issue in online platforms involving human experts
as the expert resources are often scarce. The efficient utilization of experts
in these... | 1 | 0 | 0 | 1 | 0 | 0 |
The t-t'-J model in one dimension using extremely correlated Fermi liquid theory and time dependent density matrix renormalization group | We study the one dimensional t-t'-J model for generic couplings using two

CAOS: Concurrent-Access Obfuscated Store | This paper proposes Concurrent-Access Obfuscated Store (CAOS), a construction

CAOS is that i... | 1 | 0 | 0 | 0 | 0 | 0 |
Safe Execution of Concurrent Programs by Enforcement of Scheduling Constraints | Automated software verification of concurrent programs is challenging because

Exploring the Role of Intrinsic Nodal Activation on the Spread of Influence in Complex Networks | In many complex networked systems, such as online social networks, activity

The border support rank of two-by-two matrix multiplication is seven | We show that the border support rank of the tensor corresponding to
