Metasurface‐Based Polarization‐Controlled Generation of 128‐Dimensional Vector Vortex Combs

Laser &Photonics Reviews, EarlyView.
The generation and continuous control of 128‐dimensional vector vortex combs using a single metasurface is reported. This work creates a class of structured light that uniquely integrates ultrahigh dimensionality with vector properties, and represents a crucial step toward on‐chip, reconfigurable generators for ultrahigh‐dimensional vector structured ...

Manifold Learning and the Quantum Jensen-Shannon Divergence Kernel [PDF]

, 2013
The quantum Jensen-Shannon divergence kernel [1] was recently introduced in the context of unattributed graphs where it was shown to outperform several commonly used alternatives. In this paper, we study the separability properties of this kernel and we propose a way to compute a low-dimensional kernel embedding where the separation of the different ...

Model-free detection of physical order from scattering and imaging data using escort-weighted Shannon entropy and divergence matrices

Physical Review Research
We demonstrate a model-free data analysis framework that leverages escort-weighted Shannon entropy and several divergence matrices to detect phase transitions in scattering and imaging datasets.

Drivers of stability in plankton communities: dominance, asynchrony, and averaging effects across temporal, spatial and trophic scales

Oikos, EarlyView.
The origins of ecosystem stability have long intrigued ecologists. Recent theoretical advancements highlight three primary mechanisms driving stability: dominance, asynchrony and averaging. While plant community stability has been extensively studied, our understanding of marine community stability remains limited. Plankton, as key components of marine

Evaluation of degraded images using adaptive Jensen-Shannon divergence

, 2013
This paper investigates the properties of the Jensen-Shannon divergence for visual quality assessment. It will be shown that Jensen-Shannon divergence is a potential adaptive tool thanks to a good correlation with human perception, a reduced ...

Parenting as Civic Action: A Relational Framework for Citizenship

The British Journal of Sociology, EarlyView.
ABSTRACT This article conceptualizes parenting as a form of civic action. Identifying a relational turn in theories of citizenship, we propose an analytical framework for examining civic meanings in everyday parental acts. Foregrounding the intersubjective and intergenerational nature of state–citizen relations, the framework expands existing theories ...

Appraisal and gender

Real Estate Economics, EarlyView.
AbstractWe test for gender differences in the real estate appraisal industry. We ask whether female appraisers evaluate different types of properties and whether they value the properties differently compared to their male counterparts. We largely do not find any statistically or economically significant differences between male and female appraisers ...

Comparison of Three Sympatric Desert Lizards: Digestive Tract Structure, Digestive Enzyme Activities, Gut Microbiota, and Metabolites

Integrative Zoology, EarlyView.
We performed 16S rDNA sequencing and metabolite profiling for three sympatric lizard species—Teratoscincus roborowskii, Phrynocephalus axillaris, and Eremias roborowskii—and compared their goblet cell and enzyme activities in the digestive tract. Our study suggests that the dietary niche may promote divergence or convergence of microbiota across host ...

Epävarmuuden arviointi käyttäen Jensen–Shannon divergenssiä [PDF]

, 2021
Traditional parametric statistical inference methods, such as maximum likelihood and Bayesian inference, cannot be used to learn parameter estimates if the likelihood is intractable, for example due to the complexity of the studied phenomenon.
