On critical dynamics and thermodynamic efficiency of urban transformations [PDF]

Royal Society Open Science, 2018
Urban transformations within large and growing metropolitan areas often generate critical dynamics affecting social interactions, transport connectivity and income flow distribution.

Detection of image structures using the Fisher information and the Rao metric [PDF]

, 2004
In many detection problems, the structures to be detected are parameterized by the points of a parameter space. If the conditional probability density function for the measurements is known, then detection can be achieved by sampling the parameter space ...

Multiscale Gradient Maps Augmented Fisher Information-Based Image Edge Detection

IEEE Access, 2020
Image edge detection is an important task in image processing and pattern recognition. Edges in digital images signify image discontinuities and traditionally gradient information is utilized in finding possible edge pixels.

Fisher information approach to understand the Gompertz model

Mathematics in Applied Sciences and Engineering, 2022
As a measure of sustainability, Fisher information is employed in the Gompertz growth model. The effect of different oscillatory modulations is examined on the system's evolution and Probability Density Function (PDF).

Upper Bounds for Fisher information

Electronic Journal of Probability, 2022
The author considers random vectors \(X\) in \(\mathbb R^n\) with density \(p\). For these vectors, upper bounds for the Fisher information in terms of total variation and norms in Sobolev spaces are found. The author refines a number of known results in this direction.

Inequalities for quantum Fisher information [PDF]

Proceedings of the American Mathematical Society, 2008
In 2003 Luo proved an inequality relating the Wigner-Yanase information and the $SLD$-information. In this paper we prove that Luo's inequality is a particular case of a general inequality which holds for any regular quantum Fisher information. Moreover we show that this general inequality is a consequence of the Kubo-Ando inequality that states that ...

Comparative Drug Response Profiling in Neuroblastoma Cell Lines and Patient‐Derived Tumor Organoids

Pediatric Blood &Cancer, EarlyView.
ABSTRACT High‐risk neuroblastoma remains a leading cause of pediatric cancer mortality, and improved preclinical models are needed to guide therapeutic developments. We screened seven high‐risk neuroblastoma cell lines and three patient‐derived tumor organoids with 528 compounds alongside bone marrow controls, and compared them with external datasets ...

Social Functioning Within the First Years After Pediatric Brain Tumor Diagnosis and the Relationship With Family Psychosocial Risk

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Survivors of pediatric brain tumors (PBTs) can experience long‐term social difficulties, impacting quality of life. Beyond medical and environmental factors, family psychosocial risk may play a role in social outcomes by shaping the caregiving environment and may provide intervention options.

Fisher Information Dark States and plasmonic resonances [PDF]

EPJ Web of Conferences
In this talk, we discuss the effect of plasmonic resonances on the Fisher information in the far field. We consider a metallic nanowire embedded in a silicon substrate, illuminated by a dark-field focused spot, and we investigate how its position can be ...

Different Metrics for Singular Value Optimization in Near-Field Antenna Characterization

Sensors, 2021
We deal with the use of different metrics in the framework of the Singular Value Optimization (SVO) technique for near-field antenna characterization. SVO extracts the maximum amount of information on an electromagnetic field over a certain domain from ...
