title: Supplementary material for 'Ferrofluidic Wavy Taylor Vortices under alternating magnetic field' from Ferrofluidic wavy Taylor vortices under alternating magnetic field

description: Many natural and industrial flows are subject to time-dependent boundary conditions and temporal modulations (e.g. driving frequency), which significantly modify the dynamics compared with their static counterparts. The present problem addresses ferrofluidic wavy vortex flow in Taylor–Couette geometry, with the outer cylinder at rest in a spatially homogeneous magnetic field subject to an alternating modulation. Using a modified Niklas approximation, the effect of frequency modulation on nonlinear flow dynamics and appearing resonance phenomena are investigated in the context of either period doubling or inverse period doubling.This article is part of the theme issue ‘Taylor–Couette and related flows on the centennial of Taylor’s seminal <i>Philosophical Transactions</i> paper (Part 1)’.

title: NIRPed

description: A narrowband near-infrared (NIR) imaging system is developed, combined with LiDAR to obtain nighttime driving scene images and distance information of pedestrian targets in the images, and constructed a large-scale nighttime pedestrian dataset (NIRPed) containing distance attributes. Unlike VIS, NIR is difficult to detect by human eyes, so it does not affect other road users and is not restricted by traffic laws; narrowband NIR is outside the VIS spectral band and its imaging can greatly weaken the interference of uneven VIS in nighttime driving scenes. With the help of supplementary light, narrowband NIR imaging quality will be significantly improved.

title: How microbreweries flooded Europe: mapping a new phenomenon in the beer industry

description: Europe has experienced a major boom of new breweries over the last thirty years, with thousands of new breweries being set up, even in regions where brewing has no history. So far, however, this microbrewing wave has not been systematically mapped. This paper presents a unique database of European breweries from 1990–2020. Using a series of maps and statistical analyses, it shows how breweries have gradually spread across Europe. Initially, microbreweries were being established in countries that are in a declining stage of the beer life-cycle from industrial breweries. After 2005 (and particularly in the 2010s), breweries reached other regions through neighbouring and hierarchical spatial diffusion.

title: Mapping the clouds: the matter of data centers

description: The social spatial geographies of telecommunications and their infrastructures have long interested scholars in the social sciences, and in urban geography specifically. This paper focuses on data centers. Much effort has been placed in preserving the notion that data centers are ‘clouds’, a terminology that obfuscates the real human geographies of cyberplaces. In this map-making exercise, we visualize the sociopolitical human geographies of data centers, and provoke the reader to consider the impacts that data centers have on residents and their environments. The maps shown in this paper suggest four trends. First, hyperscale data center owners are building near large waterways, signifying a shift in location preferences. Second, data centers stress local administrations, financing, and availability of upstream resources, as hyperscale data centers step up their input needs. Third, data center development is state-led. Fourth the competition for data center industries unfolds across a multi-level governance context.

title: Rural tourism in Portugal: moving to the countryside

description: The maps produced in this article allow an extended interpretation of rural tourism’s development in mainland Portugal by identifying spatio-temporal patterns, relationships, and connections. This is accomplished through the superimposition of multiple thematic layers and kernel density analysis to potentially predict rural tourism’s ruralisation patterns. The maps demonstrate that the development of rural tourism in Portugal observed a centrifugal and dispersive pattern, spreading from semi-urban to deep-rural areas. The analysis is further refined by applying the CHAID algorithm helping to show that the more recent rural tourism establishments are avoiding towns and villages and locating closer to agricultural land and protected areas. The maps and the complementary analyses provide a multidimensional understanding of rural tourism’s spatial development exemplified in complex relationships between location factors and distinct rural tourism accommodation typologies.

title: Two decades of ‘Brain Drain’ in Olomouc (Czechia)

description: This paper and accompanying map aim on the issue of brain drain (otherwise known as Human Capital Flight) concerning cultural and creative industries. The study is focused on the evaluation of Olomouc city, Czechia. In the case of a mid-sized city such as Olomouc, human capital flight is largely associated with cultural and creative fields, because it plays a significant part of the economy and character of the city. The ‘brain drain index’ of Czech municipalities has been calculated and visualized within the synthetic map. The study supported by a map investigated the brain drain from the local university. Moreover, four analytical side-maps which present the most important phenomena used for the Brain Drain Index calculating, and one side-map which summarizes the results of the questionnaire survey, have been visualized. The map layout is extended by description, table and a scheme which characterize the individual steps of the workflow.

title: Putting the rights of nature on the map. A quantitative analysis of rights of nature initiatives across the world

description: The <i>Rights of Nature</i> (RoN) promote a new understanding of the human environment, where natural entities are conceived as subjects with intrinsic value independent of human interests. The implementation of this idea gained momentum in the United States in 2006. One decade and a half later, the idea has spread all over the world. Despite some efforts, a sophisticated geographical inventory of the movement is missing. Building on Kauffman (2020), we identified and analysed 409 initiatives in 39 countries, creating the most comprehensive database of RoN initiatives to date. We developed a taxonomy that may guide further research. We also present two detailed maps which can help policymakers, legislators, judges, researchers, and the public at large to evaluate and compare initiatives. The findings of this investigation directly help the UN Harmony with Nature Programme and have contributed to the launch of the Eco-Jurisprudence Monitor, an online database of RoN initiatives.

title: Cultivated alien plants with high invasion potential are more likely to be traded online in China

description: Biological invasions have become a worldwide problem, and measures to efficiently prevent and control invasions are still being developed. Like many other parts of the world, China is undergoing a dramatic increase in plant invasions. Most of the currently 933 established (i.e., naturalized) plant species, of which 214 are categorized as invasive, have been introduced into China for cultivation. It is likely that many of those species are still being traded, particularly online, by plant nurseries. However, studies assessing whether naturalized and invasive species are currently being traded more or less than non-naturalized aliens are rare. We extracted online-trade information for 13,718 cultivated alien plant taxa on 1688.com, the largest website for domestic B2B in China. We analyzed how the presence in online-nursery catalogues, the number of online nurseries that offer the species for sale, and the product type (i.e., seeds, live plants and vegetative organs) differed among non-naturalized, naturalized non-invasive and invasive species. Compared to non-naturalized taxa, naturalized non-invasive and invasive taxa were 3.7 to 5.2 times more likely available for sale. Naturalized non-invasive and invasive taxa were more frequently offered as seeds by online nurseries, whereas non-naturalized taxa were more frequently offered as live plants. Based on these findings, we propose that, to reduce the further spread of invasive and potentially invasive plants, implementation of plant-trade regulations and a monitoring system of the online horticultural supply chain will be essential.

title: Data for figure 2 from Sodium chloride inhibits effective bubbly drag reduction in turbulent bubbly Taylor–Couette flows

description: Using the Taylor–Couette geometry we experimentally investigate the effect of salt on drag reduction caused by bubbles present in the flow. We combine torque measurements with optical high-speed imaging to relate the bubble size to the drag experienced by the flow. Previous findings have shown that a small percentage of air (4%) can lead to dramatic drag reduction (40%). In contrast to previous laboratory experiments, which mainly used fresh water, we will vary the salinity from fresh water to the average salinity of ocean water. We find that the drag reduction is increasingly more inhibited for increasing salt concentration; going from 40% for fresh water to just 15% for seawater. Salts present in the working fluid inhibit coalescence events, resulting in smaller bubbles in the flow and with that, decreasing the drag reduction. Above a critical salinity, increasing the salinity has no further effect on the bubble sizes in the flow and thus the drag experienced by the flow. Our new findings demonstrate the importance of NaCl on the bubbly drag reduction mechanism, and will further challenge the naval architects to implement promising air lubrication systems on marine vessels.This article is part of the theme issue ‘Taylor–Couette and related flows on the centennial of Taylor’s seminal <i>Philosophical Transactions</i> paper (Part 1)’.
