AI Article Synopsis
- Reservoir engineering can be influenced by the collective phase Φ of three coherent fields interacting with a Δ-type atom.
- The atomic system behaves differently based on the phase; it acts as a one-channel dissipation reservoir at Φ = 0(π) and a two-channel one when Φ is not equal to those values.
- This phase-dependent approach can generate stable two-mode squeezing and entanglement, which may be useful for quantum information processing applications.
Article Abstract
It is shown that the reservoir engineering can be controlled by the collective phase Φ of three coherent fields interacting with a closed Δ-type atom. We find that the atomic system acts as a one-channel dissipation reservoir when Φ = 0(π), but it behaves as a two-channel dissipation reservoir for Φ ≠ 0(π). The phase-dependent reservoir engineering provides a convenient way to produce robust two-mode squeezing and entanglement, which may find potential applications in quantum information processing.

Combining physics with computational models is increasingly recognized for enhancing the performance and energy efficiency in neural networks. Physical reservoir computing uses material dynamics of physical substrates for temporal data processing. Despite the ease of training, building an efficient reservoir remains challenging.

Although cytotoxic T lymphocytes (CTLs) activation combined with programmed cell death-1 (PD-1)/programmed cell death ligand-1 (PD-L1) axis blockade have emerged as an effective strategy to improve immunotherapeutic potency, it remains challenging to realize the spatiotemporal synergy of these two components. Herein, the study reports an engineered bacterial-based delivery system that can simultaneously promote CTLs infiltration and control PD-L1 binding protein (PD-L1 trap) release on demand at tumor site. The drug release button of this tumor targeting system is the specific temperature, which is accomplished by dual-modified melanin nanoparticles with photothermal conversion capacity on the engineered bacterial.

A smart viscose fabric with temperature and pH responsiveness and proactive antibacterial and UV protection was developed. PNCS (poly-(N-isopropylakrylamide)/chitosan) hydrogel was used as the carrier of silver nanoparticles (Ag NPs), synthesised in an environmentally friendly manner using AgNO and a sumac leaf extract. PNCS hydrogel and Ag NPs were applied to the viscose fabric by either in situ synthesis of Ag NPs on the surface of viscose fibres previously modified with PNCS hydrogel, or by the direct immobilisation of Ag NPs by the dehydration/hydration of the PNCS hydrogel with the nanodispersion of Ag NPs in the sumac leaf extract and subsequent application to the viscose fibres.

Topical transdermal drug delivery for psoriasis remains a challenge because of the poor solubility of hydrophobic drugs and the limited penetration of the stratum corneum. In this study, a near-infrared (NIR) light-responsive thermosensitive hydrogel (PDLLA-PEG-PDLLA, PLEL)-based drug reservoir is developed that directly incorporated gold nanorods (GNRs) and methotrexate (MTX) in the sol state at low temperature, which is referred to as PLEL@GNR+MTX. The in vitro anti-psoriasis experiment indicated that, GNRs, as photothermal cores of composite hydrogel, not only triggered keratinocyte apoptosis but also promoted MTX release in a synergistic manner.

The human body houses many distinct and interconnecting microbial populations with long-lasting systemic effects, where the oral cavity serves as a pathogens' reservoir. The correlation of different disease states strongly supports the need to understand the interplay between the oral tissue niche and microbiome. Despite efforts, the recapitulation of gingival architecture and physiological characteristics of the periodontal niche has yet to be accomplished by traditional cultural strategies.
