LIBS-LIF technology is proposed to enhance the spectral intensity of uranium in ores and eliminate interference achieve purpose improving detection sensitivity.

Accurately predicting antibody-antigen binding residues, i.e., paratopes and epitopes, is crucial in antibody design. However, existing methods solely focus on uni-modal data (either sequence or structure), disregarding the complementary information present multi-modal data, most predict epitopes separately, overlooking their specific spatial interactions. In this paper, we propose a novel Multi-modal contrastive learning Interaction informativeness estimation-based method for Paratope...

An increasing number of users have been attracted by location‐based social networks (LBSNs) in recent years. Meanwhile, user‐generated content online LBSNs like spatial, temporal, and information provides an ever‐increasing chance to study the human behavior movement from their spatiotemporal mobility patterns spawns a large applications. For instance, one such applications is produce personalized point interest (POI) recommendations that are interested in. Different traditional...

Abstract This paper proposes a hybrid energy harvester (HEH) based on dual-frequency-up-conversion mechanism, which is suitable for ultra-low frequency rotation. mechanism takes full advantage of the periodic excitation provided by gravity to achieve two harvesting responses in one cycle. HEH consists piezoelectric (PEH) and electromagnetic harvester. The magnet component achieves up-conversion PEH impact, also induces electrical from coil, thus coupling parts together form continuous...

Abstract We propose a new scheme based on quantum dot-bimodal cavity coupling system to realize all-optical switch and logic gates in low-photon-number regime. Suppression of mode transmission due the destructive interference effect is theoretically demonstrated by driving with two orthogonally polarized pulsed lasers at certain pulse delay. The transmitted can be selected designing laser sequence. optical high on-off ratio emerges when considering one as control. Moreover, AND/OR photon...

We theoretically study the dynamics of a strongly coupled quantum dot–bimodal microcavity system under an external magnetic field, where nondegenerate excitonic spin states caused by Zeeman effect are to both orthogonal cavity modes. develop effective electrodynamics model, demonstrate polarization-related nonlinear response linearly polarized pulse excitation calculating time-resolved intracavity photon number, and investigate dependence parameters on nonlinearity. In addition, we show...

A cavity quantum electrodynamics scheme for preparing a genuinely entangled state [A. Borras, et al., J. Phys. 40 (2007) 13407] on six two-level atoms is proposed. In the scheme, atom-cavity detuning much bigger than coupling strength and necessary preparation time shorter Rydberg-atom lifespan. Hence has two distinct features, i.e., insensitive to decay atom radiation.

We theoretically analyze the steady state emission spectrum and transient temporal dynamics in a coupled biexciton quantum dot (QD)—cavity system. For state, phonon-assisted biexciton—exciton cascade model under continuous wave (CW) excitation is presented to explain asymmetric QD—cavity intensities (intensities of cavity, exciton, peak) off-resonance condition. Results demonstrate that electron—phonon process crucial asymmetry intensity. Moreover characteristics system pulse show abundant...
