Previous studies have demonstrated that evolutionarily threatening information and goal-relevant information can both capture attention. However, some studies have suggested that goal-relevant information is prioritized over evolutionarily threatening information, while some studies have shown the opposite conclusion. The aim of the present study w...

Abstract This paper is concerned with a class of impulsive implicit fractional integrodifferential equations having the boundary value problem with mixed Riemann–Liouville fractional integral boundary conditions. We establish some existence and uniqueness results for the given problem by applying the tools of fixed point theory. Furthermore, we inv...

We consider the counterfactual protocol proposed in Phys. Rev. Lett., 103, 230501 (2009) within a device independent framework and show how its security can easily be compromised. Capitalising on the fact that the protocol is based on the use of a single photon entanglement phenomenon, we propose an equivalent protocol. It can be made secure within...

In this paper, we introduce MM*, a Multi-Directional Heuristic Search algorithm that finds the optimal meeting location under different cost functions. MM* generalizes the Meet in the Middle (MM) b...

Inducing shear slip in an underground laboratory: Workflow to constrain the full stress tensor demonstrated by application to the Bedretto Underground Laboratory

The electromagnetic field concentration effect can greatly enhance light-matter interaction and is of practical interest in applications such as wireless power transfer and sensors. Zero-index media, unusual materials with near-zero relative permittivity (ɛ) and/or permeability (µ), play a key role in tailoring the properties of electromagnetic wav...

We revisit the chiral anomaly in the quantum kinetic theory in the Wigner function formalism under the background field approximation. Our results show that the chiral anomaly is actually from the Dirac sea or the vacuum contribution in the un-normal-ordered Wigner function. We also demonstrate that this contribution modifies the chiral kinetic equ...

We study three-body decays of Λc*(2765)→Λc+π+π− by using effective Lagrangians in a nonrelativistic framework. We consider the sequential decays through Σc(2455)π and Σc*(2520)π in intermediate states which are dominant contributions. The coupling constants in the effective Lagrangians are computed in the quark model. We demonstrate that the ratio...

In this paper, we investigate a constrained optimal coordination problem for a class of heterogeneous nonlinear multi-agent systems described by high-order dynamics subject to both unknown nonlinearities and external disturbances. Each agent has a private objective function and a constraint about its output. A neural network-based distributed contr...

We report on the successful demonstration of a 150 J nanosecond pulsed cryogenic gas cooled, diode-pumped multi-slab Yb:YAG laser operating at 1 Hz. To the best of our knowledge, this is the highest energy ever recorded for a diode-pumped laser system.

The corresponding dispersionles...

Open data allows researchers to explore pre-existing datasets in new ways. However, if many researchers reuse the same dataset, multiple statistical testing may increase false positives. Here we demonstrate that sequential hypothesis testing on the same dataset by multiple researchers can inflate error rates. We go on to discuss a number of correct...

Since 1980s, the study of the extending module in the module theory has been a major area of research interest in the ring theory and it has been studied recently by several authors, among them N.V. Dung, D.V. Huyn, P.F. Smith and R. Wisbauer. Because the act theory signifies a generalization of the module theory, the author studied in 2017 the cla...

I am seeking feedback and comments. This paper offers a geometric proof to demonstrate that all infinite sets have the same cardinality (more correctly, that all infinite sets are only potentially infinite), thus eliminating the need for Cantor's transfinite numbers, and analyzes the structure of our numbering system in perpetuating certain misunde...

This paper demonstrates the application of the Noether's theorem I to the potential energy Lagrangian due to the oxide voltage in a MOS device.

We consider a Gaussian multiple-access channel with random user activities where the total number of users $\ell_n$ and the average number of active users $k_n$ may be unbounded. For this channel, we characterize the maximum number of bits that can be transmitted reliably per unit-energy in terms of $\ell_n$ and $k_n$. We show that if $k_n\log \ell...

We classify discrete modular symmetries in the effective action of Type IIB string on toroidal orientifolds with three-form fluxes, emphasizing on T6/Z2 and T6/(Z2×Z2′) orientifold backgrounds. In the three-form flux background, the modular group is spontaneously broken down to its congruence subgroup whose pattern is severely constrained by a quan...

In this paper, we develop studies of the dynamical symmetry breaking in the Horava-Lifshitz four-fermion model for the specific case z=3 and explicitly demonstrate that for various space-time dimensions, one could arrive at the theory displaying both dynamical generation of the Lorentz symmetry for the kinetic term and arising the positively define...

Response time (RT) information has recently attracted a significant amount of attention in the literature as it may provide meaningful information about item preknowledge.

We demonstrate for the first time the transmission of OAM and vector singular beams inside an endlessly-monoradial photonic crystal fiber (AC-PCF). The high mode purity indicates that the AC-PCF can find applications in space-division multiplexing and optical sensing.

We show that the recent excess presented by KOTO in their search for KL→π0νν¯ may be due to weakly coupled scalars produced from Kaon decays. We study two concrete realizations, the minimal Higgs portal and a hadrophilic scalar model, and demonstrate that they can explain the observed events while satisfying existing limits. The simplicity of these...

Existence of global weak solutions to the continuous Oort-Hulst-Safronov (OHS) coagulation equation is investigated for coagulation kernels capturing a singularity near zero and growing linearly at infinity.

Relativistic techniques [3,4] have made it possible to give the conjectures of Goldbach and De Polignac new and hitherto unknown versions. Relativistic techniques have also made it possible to demonstrate them in their new versions. This shows the importance of the theory of mathematical relativity in the theory of numbers and that the mathematical...

Migrating cells need to coordinate extension and retraction of their protrusions to avoid fragmenting. Kopf et al. (2020. J. Cell Biol.https://doi-org.proxy.library.uu.nl/10.1083/jcb.201907154) demonstrate that microtubules help to maintain cell coherence during amoeboid migration by controlling actomyosin contractility in retracting protrusions.

In this paper, we argue that the problem of time is not a crucial issue inherent in the quantum picture of the universe evolution. On the minisuperspace model example with the massless scalar field, we demonstrate four approaches to the description of quantum evolution, which give similar results explicitly.

In addition, we demonstrate further results for gener...

The light-rays and wave fronts in a flat class of Gödel-type metric are examined to reveal the causality violating features of the space-time. Non-causal features demonstrated by the development of unusual wave front singularities are shown to be related to the non-monotonic advance of time along the light rays, as measured by a system of observers...

A species of Pottiaceae (Bryophyta) from northwestern China, northern India and central Myanmar was evaluated as a remnant of an ancient lineage. Macroevolutionary analysis demonstrated its isolated status against other species in similar, morphologically much-reduced genera of Pleuroweisieae, occasioning the description of a new genus, Eobryum R.H...

In this paper, I demonstrate that Kant's commitment to an asymmetry between the control conditions for praise and blame is explained by his endorsement of the principle Ought Implies Can (OIC). I argue that Kant accepts only a relatively weak version of OIC and that he is hence committed only to a relatively weak requirement of alternate possibilit...
