Studyi.g molecular recognition in aqueous environments is crucial for understanding biological processes. Herein, we present a series of N-doped endo-functionalized anthracene-based cavities by introducing inward-directed pyridine units. The subtle modifications can significantly affect the binding properties of these receptors, which is similar to the mutations in biological systems. Combining theoretical calculations and molecular recognition experiments demonstrated that these “mutations” have an impact on the hydrophobicity and charge distribution of the hosts, consequently significantly influencing molecular *** is crucial for understanding the intricate mechanisms of molecular-level interactions in biological receptors.

Non-Hermitian dynamics exhibits a wealth of surprising and potentially useful phenomena. However, it is typically realized by coupling a system with thermal reservoirs, which makes the system suffer from thermal fluctuations associated with the dissipation. Here, we propose a dissipation-free approach to realize non-Hermitian dynamics using a superconducting circuit composed of two resonators and a superconducting qutrit. The non-Hermiticity arises in the dynamical matrix for the evolution of the two resonators in the Heisenberg picture, via a photon-number non-conserved dynamics. The energy spectrum of the non-Hermitian dynamical matrix can be retrieved by measuring the state of the two resonators, and a phase transition of the energy spectrum can be observed by varyi.g the control parameters. In the realization of the non-Hermitian dynamics, the dissipation of the system and the post-selection are not required. Thus, the approach is implemented in a deterministic way, and the reservoir-induced noise is suppressed. Numerical simulations indicate that the energy spectrum of the non-Hermitian dynamical matrix obtained via the measurement of the resonators is in accordance with the theoretical prediction. Moreover, we demonstrate the parity discrimination for the state of two four-level qudits as an application, exhibiting the potential of the non-Hermitian dynamics in the field of quantum measurement. This work opens a new avenue for the realization of non-Hermitian dynamics and may have a significant implication in exploring the non-Hermitian phenomena.

将水泥窑协同处置固废技术用于水泥生产是一种环保和资源化利用的有效途径。但固废中的部分重金属会通过熟料进入到水泥中,在水泥产品的使用过程中存在释放或浸出的潜在风险。为了降低碳化作用下水泥混凝土中重金属浸出量,通过外掺矿物掺合料研究掺合料对重金属浸出性能的影响。结果表明:粉煤灰和矿渣作为矿物掺合料能够优化混凝土的微观结构,在混凝土内部形成了一种含Cr和Ca的无定形复合氢氧化物沉淀,大幅降低Cr和Cr^(6+)的浸出量,其浸出量小于GB 3838-2002的V类地表水限值。

优化劳动力资源配置是人口红利消退趋势下提升全要素生产率的高质量方案。本文将数字消费纳入一个多部门竞争均衡的资源错配框架中,借助理论模型实证检验了以平台经济为代表的数字消费对劳动力资源错配的非线性影响及机制。研究表明:第一,数字消费规模对劳动力资源错配呈现出显著的“倒U形”非线性影响,且我国数字消费已处于对劳动力再配置的优化阶段,该结论经一系列检验后依然具有稳健性。第二,数字消费对劳动力资源错配的影响随着地理区位、环境规制以及资本配置效率的不同呈现出显著的异质性。第三,市场化进程、产业集聚以及政府经济目标是调节数字消费规模对劳动力资源错配“倒U形”非线性关系的重要机制。其中,市场化进程的深入会导致极值点向右偏移,并强化非线性关系;产业集聚水平、政府经济目标的提高使极值点向左移动,并弱化非线性关系。研究结果丰富了数字时代劳动力再配置理论,为发展新质生产力提出了新方案和新思路。
