title: The Least Cost Directed Perfect Awareness Problem - Benchmark Instances and Solutions

description: This dataset contains complementary data to the paper "The Least Cost Directed Perfect Awareness Problem: Complexity, Algorithms and Computations" [1]. Here, we make available two sets of instances of the combinatorial optimization problem studied in that paper, which deals with the spread of information on social networks. We also provide the best known solutions and bounds obtained through computational experiments for each instance.

The first input set includes 300 synthetic instances composed of graphs that resemble real-world social networks. These graphs were produced with a generator proposed in [2]. The second set consists of 14 instances built from graphs obtained by crawling Twitter [3].

The directories "synthetic_instances" and "twitter_instances" contain files that describe both sets of instances, all of which follow the format: the first two lines correspond to:




where and are the number of vertices and edges in the graph. Each of the next lines contains:

 

where identifies a vertex while and are the cost and threshold associated to that vertex. Each of the remaining lines contains:

 

where and identify an ordered pair of vertices that determines a directed edge with weight .

The directories "solutions_for_synthetic_instances" and "solutions_for_twitter_instances" contain files that describe the best known solutions for both sets of instances, all of which follow the format: the first line corresponds to:



where is the number of vertices in the solution. Each of the next lines contains:



where identifies a seed vertex. The last line contains:



where is the solution cost.

Lastly, two files, namely, "bounds_for_synthetic_instances.csv" and "bounds_for_twitter_instances.csv", enumerate the values of the best known lower and upper bounds for both sets of instances.

title: Lead isotope data for metal artefacts, marls and shales

description: Lead isotope compositions for metal samples 1 to 30 and 32 (31 was excluded) and samples 33–36 (marls, shales) were submitted as small chips. The samples were analysed by multicollector-inductively coupled plasma mass spectrometry (MC-ICP-MS) at the University of Melbourne, Australia. Samples (1–241 mg) were weighed into Savillex PFA beakers and reacted with 7M HNO3 (2 mL, 120°C, 15 h). Cu-rich samples formed blue solutions with minor residue while marl/ shale samples produced abundant residue. After drying, the samples were re-dissolved in 0.6M HBr, followed by Pb extraction on small (15 × 0.4 mm) beds of AG1-X8 (100–200 mesh) anion resin, using the HBr-HCl technique. Pb isotope ratios were measured on a Nu Plasma MC-ICP-MS with sample introduction via a low-uptake PFA nebuliser and Aridus desolvator. Data were collected using total Pb signal of 10–12 V, and instrumental mass bias was corrected using thallium doping (Woodhead, 2002). The thallium doping technique is expected to yield iPb/204Pb results with an external precision of 0.04%–0.08% (2std dev). This is confirmed by the results for the SRM 981 Pb standard, analysed as unknowns in the same sessions. Seven analyses of Pb extracted from the BCR-2 reference basalt show greater variability, but the average agrees with the GeoREMpreferred composition (http://georem.mpch-mainz.gwdg.de) and is consistent with the long-term laboratory average and with TIMS reference data.

title: Chemical composition (EPMA)

description: The chemical composition of 28 samples (nos. 1–26, 30, 32) was determined at the Polish Geological Institute—National Research Institute in Warsaw using a Cameca SX-100 electron microprobe (EPMA). The amount of metallic material in sample no. 31 was too small for testing. Therefore, it was excluded from further analyses. Metal samples were obtained using a micro-drill and HSS drills with a diameter of 1–2 mm. Drilling chips or small pieces up to 1.0 mm in length were mounted in epoxy resin in 1-inch discs. Samples were then polished with diamond paste and carbon coated to obtain electrical conductivity. Detailed photographs were taken, using both optical and scanning electron microscopes. Analytical conditions of the EPMA were set to 15 kV of accelerating voltage and 20 nA beam current. The diameter of the electron beam (spot size) was set to 50 μm (samples 1, 3, 4, 5, 18, 19, 20, 24, 25) and 10 μm (2, 6, 7–17, 21, 22, 23, 26, 30, 32), depending on the available homogeneous area of the samples. Due to a variable composition at the μm-scale, approximately 20 areas (15–22) were analysed per each sample. The following standards used and corresponding X-ray lines were used: Si Kα wollastonite, Al Kα orthoclase, S Kα pyrite, Ca Kα wollastonite, Ag Lα hessite, Sb Lα InSb, Sn Lα cassiterite, Cl Kα vanadinite, Bi Mβ Bi2Se3, PbMβ galena, Zn Kα ZnS, Se Lβ ZnSe, As Lβ FeAsS, Cu Kα CuFeS2, Ni Kα Ni metal, Co Kα Co metal, Fe Kα pyrite, Mg Kα diopside, Au Mα Au metal, Hg Mβ cinnabar.

title: Living in the mountains: thermal ecology and freezing tolerance of the lizard Abronia taeniata (Squamata: Anguidae)

description: The impact of daily and seasonal variation in environmental temperature on lizards is important, since their physiological processes are body temperature dependent. Lizards that occupy mountainous areas must have been favoured to colonize such habitats through selection on thermal biology traits to thermoregulate effectively; these lizards can maintain their activity near their minimum critical temperature and even have antifreeze mechanisms. Tolerance of freezing is related to the biosynthesis of cryoprotective molecules, such as glucose, whose concentration may increase after freezing. The aims of the present work were: (1) study the thermoregulation of the viviparous lizard Abronia taeniata, and (2) determine its survival and/or tolerance to freezing. This species occurs in pine forests, pine-oak forests, and mountain mesophilic forests in areas that reach freezing temperatures. We recorded air, substrate, and body temperatures at capture time of the lizards. In the laboratory, we determined the species' preferred temperature, crystallization point of the individuals and their blood glucose level before and after freezing. In addition, we recorded the operative temperatures with null models in the study area. We found out that A. taeniata sustains activity in a wide range of temperatures, is a moderate thermoregulator during autumn and winter and actively avoiding thermally favourable microhabitats in spring. In A. taeniata, the body temperatures are tightly linked to air and substrate temperatures. Seasonality had an effect over body temperature, preferred temperatures and thermoregulatory effectiveness indices. When exposed to temperatures below zero, A. taeniata showed an increase in blood glucose levels, which aided them in surviving freezing. Taken together, our results suggest that A. taeniata may sustain activity at low environmental temperatures, due to an effective behavioural thermoregulation, and in case temperatures of its habitat go below zero, is also capable of tolerate freezing.

title: Articulatory Contact Pressure & Vocal Loudness

description: This data set is derived from 13 adults with typical speech (primary spoken language is American English). The contact pressure data are from a miniature Entran EPI-BO pressure transducer attached to a 0.5 mm thick acrylic palatal mold that is customized for each participant. The transducer was positioned on the alveolar ridge approximately 2 mm posterior to the central incisors and slightly off midline (approximately 2 mm to the left of the midline). For this study, participants were seated in a sound booth with a headset microphone in place to record speech. They produced a set of short (3 syllable) sentences with three experimental phonemes embedded at the start of the second syllable. The phonemes of interest were /t/, /d/, and /s/. These were meaningful English sentences. Participants produced the sentences in four conditions: Habitual loudness, twice as loud as habitual (Loud condition), half as loud as habitual (Soft condition), and Whispered speech. A direct magnitude estimation procedure was used to elicit the loudness variation wherein Habitual was assigned a value of 100, and then participants were instructed to increase or decrease loudness relative to that value. The analysis of these data indicated a fairly consistent change in tongue-to-palate contact pressure when speaking in the Loud condition during which contact pressure increased by at least 30% compared to the Habitual condition. Additionally, contact pressures decreased when produced in the Soft condition, and to a lesser extent, the Whisper condition. These patterns of change in articulatory contact pressure were most notable and consistent for the two stop consonant, /t/ and /d/. The results highlight the interconnected nature of the phonatory and articulatory subsystems for speech. Additionally, the data may provide some insight into why loud-focused speech therapy intervention procedures may provide benefit to individuals with Parkinson's disease or other types of dysarthria. However, confirmation of changes in articulatory contact pressure in these patient populations is needed.

title: Water-Energy-Food Nexus: Multi-Actor Governance for Social Justice (Ecochamp agency))

description: The data was collected and formed part of a project called Water-Energy-Food Nexus: Multi-Actor Governance for Social Justice which is co-funded by the Dutch Research Council (NWO) in the Netherlands and the National Research Foundation (NRF) in South Africa. The objective of the project was to highlight how conditions of WEF nexus governance enhance social justice. This was achieved through a transdisciplinary approach to how a conceptual “WEF community” can be an agent of change through empowerment in WEF nexus governance by providing legal instruments that can be used and encouraging decision-making synergies from household to national levels. This was envisioned by deciphering how WEF resources and decision-making are produced, used, and distributed, their linkages, and the representation of marginal groups across scales. The opportunities and challenges of incorporating WEF community initiatives in South Africa’s legal framework were also evaluated by comparing them to the EU legislation to increase legal certainty and social justice

The data set referred herein concerns part of the project which collected quantitative data through a questionnaire of 325 households in South Africa. The households were purposively selected from Matatiele Local Municipality. This was a follow-up survey of an initial survey of 1184 households (https://data.mendeley.com/datasets/56zskrvfwf/1). The data focussed on the agency played by youth called "Ecochamps" in environmental sustainability programs

title: Database of experimental and numerical analysis of the geometry of a laboratory-scale overtopping wave energy converter using constructal design

description: The present database shows experimental and numerical results for instantaneous laboratory wave flow and discharge of water in a reservoir of a ramp with a reservoir, obtaining recommendations about the influence of the design of the ramp on the performance of an overtopping wave energy conversion device. The geometrical investigation is based on the Constructal Design method. Results for the instantaneous water surface, instantaneous water accumulated in the device reservoir for different height/length ratios of the ramp in the range (0.39 &lt;= H1/L1 &lt;= 0.80), and for water depth h1 = 0.392 m, are obtained. Results indicated that the smaller ratios of H1/L1 conducted to the higher magnitudes of water accumulated in the reservoir. Moreover, the experimental database allowed a validation of a computational model based on the finite volume method for reproduction of instantaneous wave behavior and overtopping discharges.

title: Distinct Immunological Features Compared to Lichen Planus and Oral Lichen Planus

description: Single Cell 3' libraries were prepared using standard Illumina paired-end constructs, which include the P5 and P7 adaptors. The libraries incorporated a 16 bp 10x Barcode and a 12 bp Unique Molecular Identifier (UMI) within Read 1. The cDNA fragments in the 3' Gene Expression libraries were sequenced using Read 2, while the DNA from Cell Multiplexing Oligo Feature Barcodes in the Cell Multiplexing libraries was sequenced using Read 2N. The libraries were subjected to paired-end sequencing on an Illumina platform. Sample indexing was achieved using i7 and i5 index sequences. The following standard Illumina sequencing primer sites were utilized: for the 3' Gene Expression libraries, TruSeq Read 1 and TruSeq Read 2 primers were employed; for the Cell Multiplexing libraries, Nextera Read 1 and Nextera Read 2 primers were used. This method ensured accurate and efficient sequencing of both gene expression and multiplexing features, facilitating comprehensive single-cell analysis.
