Black-Box Optimization Using Geodesics in Statistical Manifolds

open access: yesEntropy, 2015
Information geometric optimization (IGO) is a general framework for stochastic optimization problems aiming at limiting the influence of arbitrary parametrization choices: the initial problem is transformed into the optimization of a smooth function on a

Conceptual Approach for Lab‐Scale Vacuum DTB Crystallizer with Online Monitoring and Flexible Process Functionalities for Rapid Process Adjustment

open access: yesChemie Ingenieur Technik, EarlyView.
This short communication investigates the continuous evaporation crystallization in a modular lab‐scale DTBC. The focus is on the development of heat management and online monitoring for a small‐scale DTBC under vacuum conditions. AI‐based image analysis and electrochemical impedance spectroscopy are used for effective process control. Abstract Modular

The Entropy-Based Quantum Metric

open access: yesEntropy, 2014
The von Neumann entropy S( D ^ ) generates in the space of quantum density matrices  D ^ the Riemannian metric ds2 = −d2S( D ^ ), which is physically founded and which characterises the amount of quantum information lost by mixing  D ...

A continuous 500‐year sediment record of inundation by local and distant tsunamis in South‐Central Chile (40.1°S)

open access: yesThe Depositional Record, EarlyView.
Tsunami events over the past 500 years inundated Laguna Gemela West (Chile), leading to distinct sandy deposits in the lake record. This provides a complete perspective on tsunami inundation, including giant tsunamis, small local tsunamis and tsunamis that originated >100 km away from the site.

Successful School‐to‐Training Transitions—Can Individual Goal‐Striving Resources Compensate for Structural Obstacles in the Local Context?

open access: yesJournal of Adolescence, EarlyView.
ABSTRACT Introduction While it is well‐established that structural obstacles such as low local employment opportunities negatively affect adolescents’ school‐to‐work transitions, the impact of individual agency in relation to these obstacles is understudied.

Slum‐Based CAV Networks: Networking in Unyielding Poverty Situations

open access: yesStrategic Change, EarlyView.
ABSTRACT Over a billion of the world's population reside in slums. However, the configurations of their social and structural ties in these environments remain unsubstantiated. Drawing on a psychosociological rational choice perspective, we introduce theoretical explanations distinguishing slum dwellers' behavior, actions, and attitudes in community ...

Temperature and light drive physiological and transcriptional responses, modulating infection outcomes in a freshwater diatom–chytrid system

open access: yesLimnology and Oceanography, EarlyView.
Abstract Stephanodiscus binderanus is a bloom‐forming diatom abundant in winter and persisting into spring in the Laurentian Great Lakes. Climate change impacts these blooms by altering ice cover, turbidity, light penetration, and water temperature.

A characterization of hypergraphs which are products of a finite number of edges [PDF]

open access: yesRendiconti di Matematica e delle Sue Applicazioni, 1997
We prove that a hypergraph is a product of a finite number of edges if and only if it is interval-regular, satisfies the gated-edge property and has a vertex of finite degree. As a consequence, we get a characterization of Hamming graphs.

Basal Forebrain Volume and Concurrent Hallucinations and Mild Cognitive Impairment in Parkinson's Disease

open access: yesMovement Disorders Clinical Practice, EarlyView.
Abstract Background Visual hallucinations (VH) and mild cognitive impairment (MCI) often co‐occur in Parkinson's Disease (PD). Each symptom in isolation is associated with cholinergic basal forebrain (BF) atrophy. However, it is unclear whether BF integrity relates to one symptom preferentially or to their co‐occurrence, and whether this relationship ...
