Using interference for high fidelity quantum state transfer in optomechanics
We revisit the problem of using a mechanical resonator to perform the
transfer of a quantum state between two electromagnetic cavities (e.g. optical
and microwave). We show that this system possesses an effective mechanical dark
state which is immune to mechanical dissipation; utilizing this feature allows
highly efficient transfer of intra-cavity states, as well as of itinerant
photon states. We provide simple analytic expressions for the fidelity of
transferring both Gaussian and non-Gaussian states.Comment: 5 pages, 2 figure

Gas-Phase Complexes of Americium and Lanthanides with a Bis-triazinyl Pyridine: Reactivity and Bonding of Archetypes for F-Element Separations.
Bis-triazinyl pyridines (BTPs) exhibit solution selectivity for trivalent americium over lanthanides (Ln), the origins of which remain uncertain. Here, electrospray ionization was used to generate gas-phase complexes [ML3]3+, where M = La, Lu, or Am and L is EtBTP 2,6-bis(5,6-diethyl-1,2,4-triazin-3-yl)-pyridine. Collision-induced dissociation (CID) of [ML3]3+ in the presence of H2O yielded a protonated ligand [L(H)]+ and hydroxide [ML2(OH)]2+ or hydrate [ML(L-H)(H2O)]2+, where (L-H)- is a deprotonated ligand. Although solution affinities indicate stronger binding of BTPs toward Am3+ versus Ln3+, the observed CID process is contrastingly more facile for M = Am versus Ln. To understand the disparity, density functional theory was employed to compute potential energy surfaces for two possible CID processes, for M = La and Am. In accordance with the CID results, both the rate determining transition state barrier and the net energy are lower for [AmL3]3+ versus [LaL3]3+ and for both product isomers, [ML2(OH)]2+ and [ML(L-H)(H2O)]2+. More facile removal of a ligand from [AmL3]3+ by CID does not necessarily contradict stronger Am3+-L binding, as inferred from solution behavior. In particular, the formation of new bonds in the products can distort kinetics and thermodynamics expected for simple bond cleavage reactions. In addition to correctly predicting the seemingly anomalous CID behavior, the computational results indicate greater participation of Am 5f versus La 4f orbitals in metal-ligand bonding

The effect of mandatory regulation on corporate social responsibility reporting quality: evidence from China
Corporate Social Responsibility (CSR) disclosure has attracted attention from regulatory bodies and academics over the past few decades. Due to the unreliability resulted from CSR voluntary disclosure, an increasing number of researchers are calling for more government regulation on CSR disclosure. Based on 1830 standalone CSR reports disclosed by the Chinese-listed firms during 2009-2012, we examine the effect of mandatory regulation on CSR
reporting quality. We further hypothesize and test for the moderating effect of firm size and other characteristics on
the link between government regulation on CSR reporting quality. Our results suggest that government mandatory
regulation leads to an overall improvement in CSR reporting quality. We also find that this positive effect is greater
when firms are larger and have better financial performance, but less when firms are controlled by government. Our study provides a direct answer to the recent calling for mandatory disclosure on CSR reports, and helps to understand why recent studies of social disclosure regulation suggest that government interventions do not seem to resolve the problems that are generally attributed to voluntary disclosures. Our findings should be of interest to the academics,
regulators, and investors
Comprehensive Dynamic and Static Panel Model with its Application in Super Efficiency System Network
This article comparatively studies the performance of sanitation system under Super-efficiency- system Data Envelopment Analysis technology. Since the Super-efficiency-system Data Envelopment Analysis technology has the advantages such as ranking for comparison. The empirical results indicate that the efficiency of sanitation system shows an earlier raised and later decreased state in the sample interval. And the efficiency of eastern area is much higher than that of middle area and western area. Based on the performance evaluation model, this paper explores comprehensive static and dynamic models to investigate further the effect between the economic and social factors and the sanitation system performance. Research indicates that the sanitation system performance do have dynamic effects. And fiscal centralization, building sanitation performance oriented financial transfer payment system, and increasing per capital income can improve the performance of sanitation system in China
DOC: Improving Long Story Coherence With Detailed Outline Control
We propose the Detailed Outline Control (DOC) framework for improving
long-range plot coherence when automatically generating
several-thousand-word-long stories. DOC consists of two complementary
components: a detailed outliner and a detailed controller. The detailed
outliner creates a more detailed, hierarchically structured outline, shifting
creative burden from the main drafting procedure to the planning stage. The
detailed controller ensures the more detailed outline is still respected during
generation by controlling story passages to align with outline details. In
human evaluations of automatically generated stories, DOC substantially
outperforms a strong Re3 baseline (Yang et al., 2022) on plot coherence (22.5%
absolute gain), outline relevance (28.2%), and interestingness (20.7%). Humans
also judged DOC to be much more controllable in an interactive generation
setting.Comment: ACL 202
