Location graphs, compact representations of human mobility without geocoordinates, can be used to personalise location-based services. While they are more privacy-preserving than raw tracking data, it was shown that they still hold a considerable risk for users to be re-identified solely by the graph topology. However, it is unclear how this risk depends on the tracking duration. Here, we consider
The spatial distribution of buildings is one of the key factors influencing the local environment within a city. The quantitative measurement of building distribution can provide critical information for exploring local climate patterns in urban areas. Previous studies mainly focused on the two-dimensional spatial distribution of buildings and ignored the differences in height. In this study, a th
Human mobility exhibits power-law distributed visitation patterns; i.e., a few locations are visited frequently and many locations only once. Current research focuses on the important locations of users or on recommending new places based on collective behaviour, neglecting the existence of scarcely visited locations. However, assessing whether a user will return to a location in the future is hig
Detecting travel modes from global navigation satellite system (GNSS) trajectories is essential for understanding individual travel behavior and a prerequisite for achieving sustainable transport systems. While studies have acknowledged the benefits of incorporating geospatial context information into travel mode detection models, few have summarized context modeling approaches and analyzed the si
Over the past decade, scientific studies have used the growing availability of large tracking datasets to enhance our understanding of human mobility behavior. However, so far data processing pipelines for the varying data collection methods are not standardized and consequently limit the reproducibility, comparability, and transferability of methods and results in quantitative human mobility anal
Quantifying intra-person variability in travel choices is essential for the comprehension of activity–travel behaviour. Due to a lack of empirical studies, there is limited understanding of how an individual's travel pattern evolves over months and years. We use two high-resolution user-labelled datasets consisting of billions of GPS track points from ∼3800 individuals to analyse individuals’ acti
Human perception of place refers to residents' psychological feelings about urban areas. Many studies of human perceptions have focused on a specific geographic location. Whether the distribution of human perceptions in continuous city space shows specific characteristics and how to disclose these phenomena remains a direction worth exploring. Due to cities' heterogeneity, quantitatively identifyi
The emergence of passively and continuously recorded movement data offers new opportunities to study the long-term change of individual travel behaviour from data-driven perspectives. This study proposes a clustering-based framework to identify travel behaviour patterns and detect potential change periods on the individual level. First, we extract important trips that depict individual characteris
An in-depth analysis of the urban road network structure plays an essential role in understanding the distribution of urban functional area. To concentrate topologically densely connected road segments, communities of urban roads provide a new perspective to study the structure of the network. In this study, based on OpenStreetMap (OSM) roads and points-of-interest (POI) data, we employ the Infoma
Accurate activity location prediction is a crucial component of many mobility applications and is particularly required to develop personalized, sustainable transportation systems. Despite the widespread adoption of deep learning models, next location prediction models lack a comprehensive discussion and integration of mobility-related spatio-temporal contexts. Here, we utilize a multi-head self-a
In 1807, Britain outlawed the slave trade across its empire. Yet in the Cape Colony, households continued accumulating slaves for decades afterwards. New evidence from digitised tax censuses suggests the answer lies not in labour demand, but in the financial value of enslaved people as capital assets.
INTRODUCTION: Autoantibodies against insulin (IAA) are early appearing markers of autoimmunity against the pancreatic islet beta cells and predict progression to type 1 diabetes if additional islet autoantibodies also develop. It is still controversial if proinsulin rather than insulin is the primary autoantibody.METHODS: The aim of the present study was to compare the half-maximal concentration (
Wearable eye trackers and other glasses move on the wearer’s face. Such slippage can cause large offsets in the reported gaze position, and significant data loss. How much slippage may be expected during natural behavior? Here we report on the movement of two eye trackers and two smart glasses on the wearer’s head, recorded using a motion capture setup while thirty-five participants performed ten
BACKGROUND AND OBJECTIVE: BRCA1 and BRCA2 pathogenic germline variants (PGVs) are associated with higher risk of prostate cancer (PC). The IMPACT study evaluated the utility of targeted prostate-specific antigen (PSA) screening in BRCA1/BRCA2 PGV carriers. Here we report outcomes after five rounds of PSA screening in IMPACT.METHODS: Between 2005 and 2015, 3063 participants aged 40-69 yr (median 54
BACKGROUND AND OBJECTIVE: Although the effects of 5-α-reductase inhibitors (5-ARIs) on prostate-specific antigen (PSA) have been well-studied, the effects on other kallikrein markers have not been firmly established. Accordingly, a statistical model based on blood measurements of four kallikreins-known commercially as the "4Kscore"-cannot be used for men taking 5-ARIs. We investigated how finaster

Conversation published in Europanic, a publication documenting the history and development of Europan in Sweden. The conversation reflects on the author’s experience through five awarded editions of the Europan competition in Spain, Norway and Sweden. Europan is a biennial European competition and platform for architecture, housing and urban development involving multiple European countries and mu

When Ms. Ella arrives to teach the eighth grade, she shakes up the school with her radical ideas and violent discipline, building an enthusiastic following and even winning the loyalty of rebellious Dawn.The imprint she leaves on her students is both profound and damaging,

Now on the cusp of adulthood, Addie plans to start a new family to replace the one she lost, while Dorian struggles with her own violent tendencies to help raise her sister's child. But Dr.
