Mobile Phone Indicators and Their Relation to the Socioeconomic Organisation of Cities

open access: yesISPRS International Journal of Geo-Information, 2019
Thanks to the use of geolocated big data in computational social science research, the spatial and temporal heterogeneity of human activities is increasingly being revealed.

On‐Surface Indigo‐Based Bimolecular Coordination Networks with Programmable Regular or Vitreous Structure

open access: yesAdvanced Functional Materials, EarlyView.
A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...

Effect of Current on Segregation and Inclusions Characteristics of Dual Alloy Ingot Processed by Electroslag Remelting

open access: yesHigh Temperature Materials and Processes, 2019
Three dual alloy ingots were processed by electroslag remelting with 1500 A, 1800 A and 2100 A. The compositions and inclusions of ingots were analyzed by means of various analytical techniques.

Auditory Stream Segregation Can Be Modeled by Neural Competition in Cochlear Implant Listeners

open access: yesFrontiers in Computational Neuroscience, 2019
Auditory stream segregation is a perceptual process by which the human auditory system groups sounds from different sources into perceptually meaningful elements (e.g., a voice or a melody). The perceptual segregation of sounds is important, for example,

MOFs and COFs in Electronics: Bridging the Gap between Intrinsic Properties and Measured Performance

open access: yesAdvanced Functional Materials, EarlyView.
Metal‐organic frameworks (MOFs) and covalent organic frameworks (COFs) hold promise for advanced electronics. However, discrepancies in reported electrical conductivities highlight the importance of measurement methodologies. This review explores intrinsic charge transport mechanisms and extrinsic factors influencing performance, and critically ...

Bordering the area of spatial relevance for schools: a stochastic network approach using the example of Hamburg, Germany

open access: yesBelgeo, 2017
Most approaches to spatial definitions of schooling markets are based on assumptions which may cause incorrect estimates. This paper presents stochastic network analysis as an alternative approach.

Occupational and industrial segregation of female and male workers in Spain: An alternative approach [PDF]

open access: yes
This paper aims to analyze occupational and industrial segregation in the Spanish labor market by using the alternative tools proposed by Alonso-Villar and Del Río (2007), along with some new extensions put forward here. In particular, two decompositions

Iron Furnace Problem - What is the porosity distribution in the iron ore hopper? [PDF]

open access: yes, 2011
In the processing of iron ore, pellets are funneled into a furnace and reduced by contact with a gas. We consider the problem of determining whether significant spatial segregation occurs within the furnace based on pellet size.

A Smart Bio‐Battery Facilitates Diabetic Bone Defect Repair Via Inducing Macrophage Reprogramming and Synergistically Modulating Bone Remodeling Coupling

open access: yesAdvanced Functional Materials, EarlyView.
This research presents a novel implantable bio‐battery, GF‐OsG, tailored for diabetic bone repair. GF‐OsG generates microcurrents in high‐glucose conditions to enhance vascularization, shift macrophages to the M2 phenotype, and regulate immune responses.

La fragmentation de l’espace urbain postsocialiste en Albanie

open access: yesBelgeo, 2019
After 30 years of controlled and decentralized urban development, the Albanian urban space has gone through a brutal transition. At the fall of the regime in 1991, the network of small and medium-sized cities set up during communism initially survived ...
