Benchmarking one-shot distillation in general quantum resource theories

We study the one-shot distillation of general quantum resources, providing a unified quantitative description of the maximal fidelity achievable in this task, and revealing similarities shared by broad classes of resources. We establish fundamental quantitative and qualitative limitations on resource distillation applicable to all convex resource theories. We show that every convex quantum resource theory admits a meaningful notion of a pure maximally resourceful state which maximizes several monotones of operational relevance and finds use in distillation. We endow the generalized robustness measure with an operational meaning as an exact quantifier of performance in distilling such maximal states in many classes of resources including bi- and multipartite entanglement, multi-level coherence, as well as the whole family of affine resource theories, which encompasses important examples such as asymmetry, coherence, and thermodynamics.Comment: 8+5 pages, 1 figure. v3: fixed (inconsequential) error in Lemma 1

Changes of cuticular structures of Ischnodemus caspius (Heteroptera: Lygaeoidea: Blissidae) from the fifth instar to the adult

The fine cuticular structures of adult and 5th instar nymph of Ischnodemus caspius Jakovlev 1871 (Heteroptera: Lygaeoidea: Blissidae) are described, compared and illustrated using 32 SEM photos. The cuticular structures of I. caspius go through great changes during the metamorphosis from the 5th-instar nymph to the adult. The cuticular morphology of the nymph is much more complicated than that of the adult, especially the abdomen, but the long hairs on body of nymph are much more sparse and simple than those of the adult. This study will stimulate further investigations on the development and systematics of Blissidae

Fifth-instar nymphs of two species of colobathristid genus Phaenacantha from China are described, and the diagnosis of nymphal Colobathristidae and its significance in phylogenetic study are discussed

Quantifying the resource content of quantum channels: An operational approach

We propose a general method to operationally quantify the resourcefulness of quantum channels via channel discrimination, an important information processing task. A main result is that the maximum success probability of distinguishing a given channel from the set of free channels by free probe states is exactly characterized by the resource generating power, i.e. the maximum amount of resource produced by the action of the channel, given by the trace distance to the set of free states. We apply this framework to the resource theory of quantum coherence, as an informative example. The general results can also be easily applied to other resource theories such as entanglement, magic states, and asymmetry.Comment: v2. 9 pages, new references are added v1. 8 pages, no figure

Common Ingroup Identity and Racial Minority Political Solidarity

University of Minnesota Ph.D. dissertation. August 2021. Major: Psychology. Advisor: Eugene Borgida. 1 computer file (PDF); 4xiii, 420 pages.Identification with a common ingroup has been shown to reduce prejudice against former outgroup members who are included in the common ingroup, but some research suggests that prejudice reduction interventions, including common ingroup identity, can have a “paradoxical” effect on minority group members of reducing their support for social change that would improve their group’s situation. These paradoxical effects stand in contrast to research on collective action and group consciousness suggesting that identification with a disadvantaged group predicts increases in collective action and political behavior on behalf of the group. In two 3-wave panel studies, using cross-lagged panel models (CLPM) and random-intercepts cross-lagged panel models (RI-CLPM), I examined whether identification with a common ingroup that includes Whites (American identity) and identification with a common ingroup that does not include Whites (person of color, or POC, identity) have different effects on racial minorities’ attitudes toward other racial minority groups and policies that benefit racial minority groups. I generally found trait-level correlations that were consistent with the literature on common ingroup identity, paradoxical effects, collective action, and group consciousness: Among Asian (Study 1), Black (Study 2), and Latino (Study 2) Americans, common ingroup identities (American and POC) were positively associated with attitudes toward other racial groups included in the common ingroup, American identity was generally negatively associated with attitudes toward policies that benefit other minority groups, and disadvantaged group identities (racial and POC) were generally positively associated with attitudes toward policies that benefit minority groups. But except for POC identity and Asian Americans’ stereotype ratings of other minority groups and support for affirmative action (Study 1), I did not find consistent cross-lagged effects. Thus, these studies offer little support for the theory that identity predicts (and potentially causes) attitude change, at least among minority American adults.Bu, Wen. (2021).

Testing Tarnishment in Trademark and Copyright Law: The Effect of Pornographic Versions of Protected Marks and Works

Federal and state law both provide a cause of action against inappropriate and unauthorized uses that “tarnish” a trademark. Copyright owners also articulate fears of tarnishing uses of their works in their arguments against fair use and for copyright term extension. The validity of these concerns rests on an empirically testable hypothesis about how consumers respond to inappropriate unauthorized uses of works. In particular, the tarnishment hypothesis assumes that consumers who are exposed to inappropriate uses of works will find the tarnished works less valuable afterwards. This Article presents two novel experimental tests of the tarnishment hypothesis, focusing on unauthorized and unwanted pornographic versions of targeted works. We exposed over one thousand subjects to posters of pornographic versions of popular movies and measured their perceptions of the targeted movies. Our results find little evidence supporting the tarnishment hypothesis. We do, however, find some significant evidence for an alternative “enhancement” hypothesis. Some of our subjects had more favorable attitudes toward the supposedly “tarnished” movies. These results should place the burden on parties asserting tarnishment to prove that it actually exists. In addition, our data support changes to trademark and copyright laws with respect to proof of harm, fair use, and copyright term extension

New Characterizations and Properties of Matrix A∞A_\infty Weights

We provide several new characterizations of $A_{p,\infty}$-matrix weights, originally introduced by A. Volberg as matrix-valued substitutes of the classical $A_\infty$ weights. In analogy with the notion of $A_p$-dimension of matrix weights introduced in our previous work, we introduce the concepts of the lower and the upper dimensions of $A_{p,\infty}$-matrix weights, which enable us to obtain sharp estimates related to their reducing operators. In a follow-up work, these results will play a key role in the study of function spaces with $A_{p,\infty}$-matrix weights, which extends earlier results in the more restricted class of $A_p$-matrix weights.Comment: 39 pages. arXiv admin note: text overlap with arXiv:2304.0029

rac-1-(Furan-2-ylmeth­yl)-N-nitro-5-(oxolan-2-ylmeth­yl)-1,3,5-triazinan-2-imine

In the title compound C13H19N5O4, which belongs to the insecticidally active neonicotinoid group of compounds, the triazane ring exhibits a half-chair conformation. The large discrepancy between the two nitro O—N—N bond angles [116.1 (2) and 123.98 (19)°] may be attributed to intra­molecular N—H⋯O hydrogen bonding involving one of the nitro O atoms as the acceptor. The delocalization of the electrons extends as far as the nitro group, forming coplanar π-electron networks. In the crystal, inversion dimers lined by pairs of N—H⋯O hydrogen bonds occur

Effects of anisotropic composite skin on electrothermal anti-icing system

To study the effects of anisotropic thermal conductivity of composite aircraft skin on the heat transfer characteristics of electrothermal anti-icing system, the differential equation of anisotropic heat conduction was established using coordinate transformation of principal anisotropy axis. In addition, it was coupled with the heat and mass transfer model of the runback water film on the anti-icing surface to perform numerical simulation of the electrothermal anti-icing system. The temperature results of the vertical and cylindrical orthotropic thermal conduction in the rectangular and semi-cylindrical composite skin were consistent with those obtained by the traditional orthotropic model, which verified the anisotropic heat conduction model. The temperature distribution of anti-icing surface agreed well with the literature data, which validated the coupled heat and mass model of the runback water flow and the anisotropic skin. The anisotropic thermal conductivity of composite skin would make temperature change more gradual, and the effect was more significant where the curvature of the temperature curve was greater. However, the anti-icing surface of the electrothermal anti-icing system was slightly affected by the anisotropic heat conduction of the multilayered composite skin
