Urban nature-based solutions to climate change adaptation database
<p>This dataset is the result of a systematic mapping of the application of nature-based solutions (NbS) to climate change adaptation in urban areas across the world. We screened 823 potential urban NbS to climate adaptation, which resulted in the inclusion of 216 interventions worldwide from 130 cities in 55 countries within our dataset. We analysed each of the NbS according to key characteristics in terms of how these interventions are helping cities confront the grave climate change, biodiversity, and related social challenges they are facing. We further analyse the capacity for each NbS to affect change in the city it is implemented within, which ranges from incremental (shallow) change to reformistic (middle ground) and finally transformative (deep) change. The full range of climate, biodiversity, and social challenges, as well as further discussion on the meaning of these different levels of change, is described in the attached file in the coding template tab. </p> <p>The results and analysis of this database (v 1.0.0) appear in the following article:</p> <p>Goodwin, S., M.

Needs and preferences of different groups of informal caregivers towards designing digital solutions
<p>The project aimed to understand whether young adults who take care of a loved-one (young adult caregivers; YACs) differ in their perceived life balance and psychosocial functioning as compared to young adults without care responsibilities (non-YACs). In addition, this project aimed to understand how YACs evaluated a tool to support informal careg</p> <p>ivers. This tool (“Caregiver Balance”; <a href="https://balans.mantelzorg.nl">https://balans.mantelzorg.nl</a>) is specifically designed to support informal caregivers taking care of a loved-one in the palliative phase and could potentially be adapted to meet the needs of YACs. </p> <p>In this project, we collected data of 74 YACs and 246 non-YACs. Both groups completed questionnaires, and the YACs engaged in a usability test. The questionnaire data was used to compare the perceived life balance and psychological functioning between YACs and non-YACs, aged 18-25 years, and studying in the Netherlands (study 1). Furthermore, we examined the relationship between positive aspects of caregiving and relational factors, in particular, relationship quality and collaborative coping among YACs (study 2). Finally, we conducted a usability study where we interviewed YACs to understand the needs and preferences towards a supportive web-based solution (study 3).</p> <p><strong><em>Table: Study details and associated files</em></strong></p> <table> <tbody> <tr> <td>Number</td> <td>Study Name</td> <td>Study Aim</td> <td>Study Type</td> <td>Type of data</td> <td>Associated Files</td> </tr> <tr> <td>1</td> <td>Perceived life balance among young adult students: a comparison between caregivers and non-caregivers</td> <td>Compare the perceived life balance and psychological functions among student young adult caregivers aged 18-25 years (YACs) with young adult without care responsibilities</td> <td>Survey study</td> <td>Quantitative</td> <td> <ol> <li>ENTWINE_YACs_nonYACsSurvey_RawData</li> <li>ENTWINE_PerceivedLifeBalanceSurvey_YACs_nonYACs_CleanedData</li> <li>ENTWINE_ PerceivedLifeBalanceSurvey _Syntax</li> <li>ENTWINE_YACs_nonYACsSurvey_codebook</li> </ol> </td> </tr> <tr> <td>2</td> <td>Examining the relationship of positive aspects of caregiving with relational factors among young adult caregivers</td> <td>Examine the relationship of positive aspects of caregiving with relational factors, in particular, relationship quality and collaborative coping among a particular group of ICGs, young adult caregivers (YACs), aged 18-25 years.</td> <td>Survey study</td> <td>Quantitative</td> <td> <ol> <li>ENTWINE_YACs_nonYACsSurvey_RawData</li> <li>ENTWINE_PositiveAspectsCaregiving_Survey_YACs_cleanedData</li> <li>ENTWINE_PositiveAspectsCaregiving_Survey_Syntax</li> <li>ENTWINE_YACs_nonYACsSurvey_codebook</li> </ol> </td> </tr> <tr> <td>3</td> <td>Exploring the support needs of young adult caregivers, their issues, and preferences towards a web-based tool</td> <td>Explore (i) challenges and support needs of YACs in caregiving, (ii) their needs towards the content of the ‘MantelzorgBalans’ tool, and (iii) issues they encountered in using the tool and their preferences for adaptation of the tool.</td> <td>Usability study</td> <td> <p>Qualitative and Quantitative</p> </td> <td> <ol> <li>ENTWINE_Needs_Web-basedTools_YACs_Interview_Usability_RawData [to be determined whether data can be shared]</li> <li>ENTWINE_Needs_Web-basedTools_YACs_Questionnaires_RawData</li> </ol> </td> </tr> </tbody> </table> <p><strong>Description of the files to be uploaded</strong></p> <p><strong><em>Study 1: Perceived life balance among young adult students: a comparison between caregivers and non-caregivers</em></strong></p> <ol> <li>ENTWINE_YACs_nonYACsSurvey_RawData: SPSS file with the complete, raw, pseudonomyzed survey data.

Differential algebra mappings of CR3BP periodic solutions
<p>This dataset is made of twenty-three items containing polynomial mappings of families of periodic solutions of the circular restricted 3-body problem (CR3BP) [1], here the Earth-Moon and the Sun-(Earth-Moon) systems. Each file stores a list of differential algebra (DA) [2] maps representing these families with their associated domains of definition. The DA maps were computed using DA solving of two-point boundary value problem [3] and allow one to access initial conditions of solutions of the CR3BP by polynomial evaluation instead of heavy computations, provided the files containing the DA polynomials [4].</p> <p>Each family is available with three different accuracies, also called tolerances. They are, with increasing accuracy, 1e-5, 1e-8, and 1e-10. The most accurate ones have higher loading and evaluation times and use more disk space but give better approximations of the families.

Crystal Structure Solution and High Temperature Thermal Expansions of NaZr2(PO4)3-type Materials
<p>The NaZr<sub>2</sub>P<sub>3</sub>O<sub>12 </sub>(NZP) family<sub> </sub>of materials have shown low and tailorable thermal expansion properties. This dataset includes SrZr<sub>4</sub>P<sub>6</sub>O<sub>24</sub>, CaZr<sub>4</sub>P<sub>6</sub>O<sub>24</sub>, NaTi<sub>2</sub>P<sub>3</sub>O<sub>12</sub>, NaZr<sub>2</sub>P<sub>3</sub>O<sub>12</sub>, MgZr<sub>4</sub>P<sub>6</sub>O<sub>24</sub>, and related solid solutions. These materials were synthesized using the organic-inorganic steric entrapment method. The samples were characterized with in-situ high-temperature x-ray diffraction at the Advanced Photon Source and National Synchrotron Light Source II from 25 to 1500 ℃. The average linear thermal expansion of SrZr<sub>4</sub>P<sub>6</sub>O<sub>24</sub> and CaZr<sub>4</sub>P<sub>6</sub>O<sub>24</sub> was between -1 x10<sup>-6</sup>/℃ and 6 x10<sup>-6</sup>/℃ from 25 to 1500 ℃. High temperature polymorphs of CaZr<sub>4</sub>P<sub>6</sub>O<sub>24</sub> and SrZr<sub>4</sub>P<sub>6</sub>O<sub>24</sub> were solved by Fourier difference mapping and Rietveld refinement. This polymorph is present above about 1250 ℃. This work measured thermal expansion coefficients to 1500 ℃ for all samples and investigated the differences in thermal expansion mechanisms between polymorphs and between compositions. </p>
Nitrogen-15 dynamic nuclear polarization of nicotinamide derivatives in biocompatible solutions

Here, we are developing a group of dDNP polarized tracers based on nicotinamide (NAM). We synthesized 1-<sup>15</sup>N-NAM and 1-<sup>15</sup>N nicotinic acid and hyperpolarized them with dDNP, reaching (13.0±1.9)% <sup>15</sup>N polarization. We found that the lifetime of hyperpolarized 1-<sup>15</sup>N-NAM is strongly field- and pH-dependent, with T<sub>1</sub> being as long as 41 s at a pH of 12 and 1 T while as short as a few seconds at neutral pH and fields below 1 T. The remarkably short 1-<sup>15</sup>N lifetime at low magnetic fields and neutral pH drove us to establish a unique pH neutralization procedure. Using <sup>15</sup>N dDNP and an inexpensive rodent imaging probe designed in-house, we acquired a <sup>15</sup>N MRI of 1-<sup>15</sup>N-NAM (previously hyperpolarized for more than an hour) in less than one second.</p>
GEOLAB Project CTP-ISSR: monotonic and cyclic Centrifuge Tests on Piles in sand proving Innovative Solutions to enhance Structural Resilience
<p>The existing structures are facing continuous changes in the loading conditions during their life span. These changes can be caused by weather and geo-hazards events and affect the structural response which is often already weakened by aging.</p> <p>A clear understanding of the interaction between the superstructure, the foundation and the surrounding soil is one of the crucial aspects to deal with to adapt the design and maintenance to enhance the resilience of new and existing Critical Infrastructures (CI) often used way beyond their life expectancy. Besides the loading components already considered in engineering practice, CI endure loads having cyclic nature acting continuously during service life (e.g., wind) which are often disregarded in foundation design and may trigger collapse mechanisms. Indeed, they are usually modelled as equivalent-static actions thus neglecting the accumulation of generalized permanent displacements of piled foundations in terms of settlement, sliding and rotation. This lack in design approach can be attributed to very limited research contributions dealing with cyclic loads. </p> <p>The CTP-ISSR (monotonic and cyclic Centrifuge Tests on Piles in sand proving Innovative Solutions to enhance Structural Resilience) project aims at investigating via centrifuge tests the behaviour of piled foundations under different loading types. Two series of centrifuge experiments on annular shaped pile groups and isolated piles embedded in Hostun sand were carried out at an increased gravity of 50 g in the Turner Beam Centrifuge at Schofield Centre, University of Cambridge. </p> <p>To simulate prototype reinforced concrete piles, model piles, made up of cement and metal wires, were manufactured in laboratory by means of an ad-hoc mould and manual mortar pouring. Such modelling is necessary to replicate the strong dependency of pile cross-sectional moment capacity on the axial force. Piles were installed in an 850 mm steel tub filled with manually poured Hostun sand prepared with a low-to-medium relative density. </p> <p>The first test included 2 single piles ad 2 groups of 8 piles connected by a circular rigid cap clear from the soil. The model foundations were subjected to monotonic vertical loads or vertical eccentric cyclic loads of different amplitudes and frequencies. In a similar fashion, the second test included 3 single piles ad 2 pile groups. In this case, the model foundations were subjected to monotonic vertical or horizontal loads or to cyclic horizontal loads of different amplitudes and frequencies. The response of the foundation system, in terms of loads and displacements, was monitored through loads cells, Linear Variable Differential Transformers (LVDTs) and Micro-Electro-Mechanical-Systems (MEMS). A miniaturized Cone Penetration Test (mini-CPT) was used to characterize the soil before the test execution. The experimental campaign was accomplished in 10 working days (including, among the others, model preparation, execution, data acquisition and dismantle). </p> <p>The results of the experiments will serve as benchmarks for the development of a non-linear macroelement for piled foundation. Adopting this innovative approach allows the strengthening of CI resilience by adapting the traditional design and maintenance to properly consider changing loading conditions in a simple yet reliable manner. </p> <p>Researchers and practitioners will be the beneficiaries of the outcome of this research, expecting the following advantages: <br> - Innovation in design, with the possibility to properly consider cyclic loading;<br> - Improvement in identifying possible failure mechanisms and the required maintenance to enhance reliability and resilience of existing CI.</p>

Reinforcement-based processes actively regulate motor exploration along redundant solution manifolds
<p>From a baby's babbling to a songbird practicing a new tune, exploration is critical to motor learning. A hallmark of exploration is the emergence of random walk behaviour along solution manifolds, where successive motor actions are not independent but rather become serially dependent. Such exploratory random walk behaviour is ubiquitous across species, neural firing, gait patterns, and reaching behaviour. Past work has suggested that exploratory random walk behaviour arises from an accumulation of movement variability and a lack of error-based corrections. Here we test a fundamentally different idea—that reinforcement-based processes regulate random walk behaviour to promote continual motor exploration to maximize success. Across three human-reaching experiments, we manipulated the size of both the visually displayed target and an unseen reward zone, as well as the probability of reinforcement feedback. Our empirical and modelling results parsimoniously support the notion that exploratory random walk behaviour emerges by utilizing knowledge of movement variability to update intended reach aim towards recently reinforced motor actions. This mechanism leads to active and continuous exploration of the solution manifold, currently thought by prominent theories to arise passively. The ability to continually explore muscle, joint, and task redundant solution manifolds is beneficial while acting in uncertain environments, during motor development, or when recovering from a neurological disorder to discover and learn new motor actions.</p>
The Role of Operating Conditions in the Precipitation of Magnesium Hydroxide Hexagonal Platelets Using NaOH Solutions
<p>Magnesium hydroxide, Mg(OH)<sub>2</sub>, is an inorganic compound extensively employed in several industrial sectors. Nowadays, it is mostly produced from magnesium-rich minerals. Nevertheless, magnesium-rich solutions, such as natural and industrial brines, could prove to be a great treasure. In this work, synthetic magnesium chloride and sodium hydroxide, NaOH, solutions were used to recover Mg(OH)<sub>2</sub> by reactive crystallization. A detailed experimental campaign was conducted aiming at producing grown Mg(OH)<sub>2</sub> hexagonal platelets. Experiments were carried out in a stirred tank crystallizer operated in single- and double-feed configurations. In the single-feed configuration, globular and nano-flakes primary particles were obtained, as always reported in the literature when NaOH is used as a precipitant. However, these products are not complying with flame retardant applications that require large hexagonal Mg(OH)<sub>2</sub> platelets. This work suggests an effective precipitation strategy to favour crystal growth while, at the same time, limiting nucleation mechanism. The double-feed configuration allowed the synthesis of grown Mg(OH)<sub>2</sub> hexagonal platelets. The influence of reactants flow rates, reactants concentrations and reaction temperature was analyzed. SEM pictures were also taken to investigate the morphology of Mg(OH)<sub>2</sub> crystals. The proposed precipitation strategy paves the road to satisfy flame retardant market requirements.</p>
