Dogs are exceptionally successful at interpreting human pointing gestures to locate food hidden in one of two containers. However, it has repeatedly been questioned whether dogs rely on the pointing gesture or their success is increased by subtle cues from their human handler. In two experiments we used a standard two-way object-choice task to focus on this potential Clever Hans effect. We inve...

Addition is the most basic operation of computing based on a bit system. There are various addition algorithms considering multiple number systems and hardware, studies for more efficient still ongoing. Quantum qubits as information unit asks design new because it is, physically, wholly different from existing frequency-based in which minimum bit. In this paper, we propose an quantum circuit mo...

In our project we implemented a system from transferring money without using Proof-of-Work, but consensus algorithms. First we implemented it using Paxos[11], that does not support Byzantine failures and needs a central authority to decide which nodes participate on the agreements. Then we reimplemented it using Stellar Consensus Protocol[2], that has no central authority and allows Byzantine n...

A recent theoretical paper [1] proposes a scheme for entanglement swapping utilizing acousto-optic modulators without requiring a Bell-state measurement. In this comment, we show that the proposal is flawed and no entanglement swapping can occur without measurement.

In this article, we present the continuing work on a SARS model without quarantine by Hsu and Hsieh [Sze-Bi Hsu, Ying-Hen Hsieh, Modeling intervention measures and severity-dependent public response during severe acute respiratory syndrome outbreak, SIAM J. Appl. Math. 66 (2006) 627–647]. An “acting basic reproductive number” ψ is used to predict the final size of the susceptible population. We...

Branching ratios and CP noninvariance of nonleptonic rare exclusive B decays without charm particles in the final state are studied. Decay channels, such as Bd K tt, K* p, B, K p, K p, Bd, K K,K* K,K K*,K* K, etc. , that can give direct evidence for the W-loop diagrams are pointed out. Some decay modes have large (tens of percent) CP noninvariance of partial-decay-rate diff'erences. Decays such...

Abstract We have explored an extended seesaw model accommodating a keV sterile neutrino adopting U (1) B − L symmetry. This provides natural platform for achieving resonant leptogenesis to account the observed baryon asymmetry of Universe (BAU). The required lepton is sourced by CP violating decay lightest heavy right-handed Standard Model leptons and Higgs. presence light in brings out enhance...

The implications of the many proper time amplitudes for the process Φ → K o + ¯ K o was discussed in a recent letter of B. Kayser and L. Stodolsky who predicted a small correction (∼ 5%) to the usually predicted phase oscillation frequency for forthcoming Φ factory experiments. Based on previous work (also using the many proper times formalism), we predicted a much larger correction factor ≈ 2....

The treatment of chronic total occlusions is complex and associated with several risks and problems. Among therapeutic options including bypass surgery and medical therapy PCI represents an important strategy. PCI with stents, however, has limitations in such lesions due to characteristics like lesion length, unknown reference diameter and delayed stent coverage. Drug coated balloons have shown...
