This paper presents a study conducted in naturalistic setting with data collected from an interactive art installation. The audience is challenged in a Turing Test for artistic creativity involving recognising human-made versus AI-generated drawing strokes. In most cases, people were able to differentiate human-made strokes above chance. An analysis conducted on the images at the pixel level shows a significant difference between the symmetry of the AI-generated strokes and the human-made ones. However we argue that this feature alone was not key for the differentiation. Further behavioural analysis indicates that people judging more quickly were able to differentiate human-made strokes significantly better than the slower ones. We point to theories of embodiment as a possible explanation of our results. © 2021, Springer Nature Switzerland AG.

We consider the problem of computing a function of n variables using noisy queries, where each query is incorrect with some fixed and known probability p ∈ (0, 1/2). Specifically, we consider the computation of the OR function of n bits (where queries correspond to noisy readings of the bits) and the MAX function of n real numbers (where queries correspond to noisy pairwise comparisons). We show that an expected number of queries of (formula presented) is both sufficient and necessary to compute both functions with a vanishing error probability δ = o(1), where DKL(p||1−p) denotes the Kullback-Leibler divergence between Bern(p) and Bern(1−p) distributions. Compared to previous work, our results tighten the dependence on p in both the upper and lower bounds for the two functions. © 2023, CC BY.

computational modeling helps neuroscientists to integrate and explain experimental data obtained through neurophysiological and anatomical studies, thus providing a mechanism by which we can better understand and predict the principles of neural computation. computational modeling of the neuronal pathways of the visual cortex has been successful in developing theories of biological motion processing. This review describes a range of computational models that have been inspired by neurophysiological experiments. Theories of local motion integration and pattern motion processing are presented, together with suggested neurophysiological experiments designed to test those hypotheses. © 2023, CC BY-NC-ND.

Over the past two decades, the clock speed, and hence, the singlecore performance of microprocessors has already stagnated. Following this, the recent faltering of Moore's law due to the CMOS fabrication technology reaching its unavoidable physical limit has presaged daunting challenges for designing power-efficient and ultrafast microprocessors. To overcome these challenges, vigorous efforts have been made to develop new more-than-Moore technologies and architectures for computing. Among these, nanophotonic integrated circuits based computing architectures have shown revolutionary potential. Among recent demonstrations of nanophotonic circuits for computing, a polymorphic, nanophotonic ALU (PoN-ALU) carries a notable importance since it has shown very high flexibility, high speed, and low power consumption for computing. In this paper, we carry out a design space exploration of this PoN-ALU to derive new design guidelines that can help scale the speed and energy efficiency of PoNALU even further. © 2021 ACM.

Perturbatively corrected ring-polymer instanton theory for accurate tunneling splittings

We introduce an approach for calculating perturbative corrections to the ring-polymer instanton approximation to tunneling splittings (RPI+PC), by computing higher-order terms in the asymptotic expansion in h. The resulting method goes beyond standard instanton theory by using information on the third and fourth derivatives of the potential along the tunneling path to include additional anharmonic effects. This leads to significant improvements both in systems with low barriers and in systems with anharmonic modes. We demonstrate the applicability of RPI+PC to molecular systems by computing the tunneling splitting in full-dimensional malonaldehyde and a deuterated derivative. Comparing to both experiment and recent quantum-mechanical benchmark results, we find that our perturbative correction reduces the error from -11% to 2% for hydrogen transfer and performs even better for the deuterated case. This makes our approach more accurate than previous calculations using diffusion Monte Carlo and path-integral molecular dynamics, while being more computationally efficient. © 2023, CC BY.

The combination of integrability and crossing symmetry has proven to give tight non-perturbative bounds on some planar structure constants in N=4 SYM, particularly in the setup of defect observables built on a Wilson-Maldacena line. Whereas the precision is good for the low lying states, higher in the spectrum it drops due to the degeneracies at weak coupling when considering a single correlator. As this could be a clear obstacle in restoring higher point functions, we studied the problem of bounding directly a 4-point function at generic cross ratio, showing how to adapt for this purpose the numerical bootstrap algorithms based on semidefinite programming. Another tool we are using to further narrow the bounds is a parity symmetry descending from the N=4 SYM theory, which allowed us to reduce the number of parameters. We also give an interpretation for the parity in terms of the Quantum Spectral Curve at weak coupling. Our numerical bounds give an accurate determination of the 4-point function for physical values of the cross ratio, with at worst 5-6 digits precision at weak coupling and reaching more than 11 digits for't Hooft coupling √λ/4π∼ 4.

The paper concerns the analysis of global minimizers of a Dirichlet-type energy functional defined on the space of vector fields H1(S,T), where S and T are surfaces of revolution. The energy functional we consider is closely related to a reduced model in the variational theory of micromagnetism for the analysis of observable magnetization states in curved thin films. We show that axially symmetric minimizers always exist, and if the target surface T is never flat, then any coexisting minimizer must have line symmetry. Thus, the minimization problem reduces to the computation of an optimal one-dimensional profile. We also provide a necessary and sufficient condition for energy minimizers to be axially *** Codes 35A23, 35R45, 49R05, 49S05, 82D40 Copyright © 2023, The Authors. All rights reserved.

This paper considers the dynamical environment of 65803 Didymos and applies the center manifold approximation method to compute quasi-periodic orbits. Its dynamical environment is known to be complex due to the unique shapes of the primaries and the nonexistence of symmetric properties which is useful to obtain Lyapunov or halo orbits. The center manifold method is successfully applied and extended in Didymos. This method is beneficial because it does not require the initial guess nor bifurcation process and has a lower computational cost. Multiple shooting is introduced into the center manifold method to calculate trajectories with the longer propagation time. © 2021, Univelt Inc. All rights reserved.
