Quantum Dynamical Resource Theory under Resource Non-increasing Framework
We defne the resource non-increasing (RNI) framework to study the dynamical
resource theory. With such a defnition, we propose several potential
quantifcation candidates under various free operation sets. For explicit
demonstrations, we quantify the quantum dynamical coherence in the scenarios
with and without post-selective measurements. Correspondingly, we show that
maximally incoherent operations (MIO) and incoherent operations (IO) in the
static coherence resource theory are free in the sense of dynamical coherence.
We also provide operational meanings for the measures by the quantum
discrimination tasks. Moreover, for the dynamical total coherence, we also
present convenient measures and give the analytic calculation for the amplitude
damping channel.Comment: 11 pages, 1 figur
A Closer Look at the Self-Verification Abilities of Large Language Models in Logical Reasoning
Logical reasoning has been an ongoing pursuit in the field of AI. Despite
significant advancements made by large language models (LLMs), they still
struggle with complex logical reasoning problems. To enhance reasoning
performance, one promising direction is scalable oversight, which requires LLMs
to identify their own errors and then improve by themselves. Various
self-verification methods have been proposed in pursuit of this goal.
Nevertheless, whether existing models understand their own errors well is still
under investigation. In this paper, we take a closer look at the
self-verification abilities of LLMs in the context of logical reasoning,
focusing on their ability to identify logical fallacies accurately. We
introduce a dataset, FALLACIES, containing 232 types of reasoning fallacies
categorized in a hierarchical taxonomy. By conducting exhaustive experiments on
FALLACIES, we obtain comprehensive and detailed analyses of a series of models
on their verification abilities. Our main findings suggest that existing LLMs
could struggle to identify fallacious reasoning steps accurately and may fall
short of guaranteeing the validity of self-verification methods. Drawing from
these observations, we offer suggestions for future research and practical
applications of self-verification methods.Comment: work in progres
Whole-genome sequencing of cultivated and wild peppers provides insights into Capsicum domestication and specialization
As an economic crop, pepper satisfies people's spicy taste and has medicinal uses worldwide. To gain a better understanding of Capsicum evolution, domestication, and specialization, we present here the genome sequence of the cultivated pepper Zunla-1 (C. annuum L.) and its wild progenitor Chiltepin (C. annuum var. glabriusculum). We estimate that the pepper genome expanded similar to 0.3 Mya (with respect to the genome of other Solanaceae) by a rapid amplification of retrotransposons elements, resulting in a genome comprised of similar to 81% repetitive sequences. Approximately 79% of 3.48-Gb scaffolds containing 34,476 protein-coding genes were anchored to chromosomes by a high-density genetic map. Comparison of cultivated and wild pepper genomes with 20 resequencing accessions revealed molecular footprints of artificial selection, providing us with a list of candidate domestication genes. We also found that dosage compensation effect of tandem duplication genes probably contributed to the pungent diversification in pepper. The Capsicum reference genome provides crucial information for the study of not only the evolution of the pepper genome but also, the Solanaceae family, and it will facilitate the establishment of more effective pepper breeding programs
Multi-Source Data Analysis of Mesoscale Eddies and Their Effects on Surface Chlorophyll in the Bay of Bengal
Mesoscale eddies are important to ocean circulation due to their roles in the transport of mass, energy, and heat. This study employs a combination of data sources to initiate a statistical analysis of eddy spatiotemporal characteristics in the Bay of Bengal (BOB) to elucidate the sea surface and vertical structures of the eddies and their impacts on sea surface chlorophyll (Chl) distributions. The results suggest that 1237 cyclonic eddies (CEs) and 1121 anticyclonic eddies (AEs) were detected in 26 years. The number of two eddy polarities was almost the same, and most of them spread to the west or southwest direction. The vertical change of temperature (T) and salinity (S) caused by the eddies is studied and the anomalous eddies, i.e., a CE (AE) eddy with warm (cold) water at the center, are mainly distributed on the northeast side of the Island of Sri Lanka. Furthermore, CEs are found to increase Chl concentration in the surrounding sea by approximately 11.15%, while AEs decrease concentrations also by approximately 11.25%. Changes in Chl concentrations occur most rapidly during the mature and intensification eddy phases. Observations also indicate that the strong local current and wind fields are the primary mechanisms in eddy generation
Thermally Stable Guest-Host Polyetherketone Poled Polymer for Electro-Optical Applications
The high glass transition temperature polymer polyetherketone doped with disperse red 13 (DR13/PEK-c) has been prepared by the spin-coating method. Through in situ second-harmonic generation, the corona poling temperature was optimized by measuring the temperature dependence of the in situ second-harmonic generation signal intensity under the poling electric field. The linear electro-optic coefficients of the poled polymer films have been determined at 632.8 nm by using a simple interferometric technique. The polymer system was measured after 13 000 h, and found that it remained at 80% of its initial value
