This dataset contains the data used for the figures, tables and regressions in our paper "Imputing Away the Ladder". They include both time-series (for all countries where available) for official GDP figures under different systems of national accounts (SNA 68, SNA 93 and SNA 2008), as well as time-series constructed in line with Basu and Foley's (2013) concept of Narrow-Measured Value-Added (NMVA) - that is, GDP excluding all sectors for which value-added had been imputed.
This dataset is uploaded as supplementary material for article "A new PARAFAC-based algorithm for HPLC-MS data treatment: Herbal extracts identification"

Data result from careful measurements with hot wires in an aerodynamic channel and from flow visualization in a hydraulic channel to study the wake behavior after pairs of finite cylinders with 25 mm diameter and pitch-to-diameter ratio p/d = 1.26, at several angular positions to the flow, 0o (side-by-side), 2.5o, 5o, 15o, 25o, 35o, 45o, 75o and 90o (tandem).
The aerodynamic channel was made of acrylic, with a cross section of 0.147 m x 0.193 m. The flow velocity was 10 m/s, turbulence intensity of about 1%, Reynolds number 1.66x104.
The two circular cylinders were made of PVC with a diameter of 25.1 mm, and a blockage ratio of 13% - 26%, depending on the angular position of the cylinders.
Wake flow velocity was measured with a DANTEC StreamLine CTA system with two DANTEC 55P11 probes. Data acquisition was performed by a USB 16-bit NI USB-9162 A/D board, sampling frequency 1000 Hz, low pass filter 300 Hz, 131,072 samples, time series 131.072 s long.
The cylinders and the probes were numbered as 1 and 2. Cylinder number one is on the left side of the flow stream. At positions different of 0o, cylinder number 2 faced the flow firstly.
Flow visualizations were made in a closed-circuit hydraulic channel with the same dimensions as the aerodynamic channel. The Reynolds number was 1.97x10³ (kinematic viscosity of the water at 15 ºC was 1.14 x 106 m²/s), turbulence intensity about 4%.
Two ink tanks provided dye, injected by gravity in the flow through 3 mm diameter flexible PVC tubes inside the cylinders. Video resolution was 1080 x 720 pixels at 30 FPS. Each movie was 25 minutes long. A mirror at 45° with the camera allowed simultaneous top and side view.
From top view images, a time series of the angle formed between the tangent to the cylinder wall and the deflected flow from the gap between the cylinders was generated with Tracker and Matlab software. Angles were measured at each 200 frames (6.67 s), sampling frequency of 0.15 Hz.
Data are in .txt format to be read by almost all software. Excerpts from the movies from the flow visualizations are in .mkv format.

This dataset contains information about interconnect delays of different supercomputers during data transmissions using different commutation patterns.
All measurements are structured by folders. Each folder contains several files, their contains can be interpreted as follows:
description.txt - text file, containing information about collected measures: name of supercomputer, date of testing, number of tested nodes, number of tested process, network_tests2 test mode and parameters for launch such as begin message length in bytes, end message length in bytes, change of message length in bytes after all iterations passed, number of iterations of testing on one message length.
network_hosts.txt - text file, containing names of hosts, which were used for launch.
Another files are information about delays represented as different statistics: median, standard deviation, min and mean.
All data is stored in NetCDF4 format. In our dataset these files contain following variables:
"data" - 3-dimensional array with information about delays between different MPI-processes, first axis represent message length, second - number of "sender" process, third - number of "receiver" process;
"num_proc" - number of tested processes;
"beg_mes_len" - begin message length in bytes;
"end_mes_len" - end message length in bytes;
"step_length" - change of message length in bytes after all iterations passed.

Data result from careful measurements with hot wires in an aerodynamic channel and from flow visualization in a hydraulic to study the bistability phenomenon after pairs of finite cylinders with 25 and 32 mm diameter and aspect ratios of 3 and 4. Measurements were performed in the wake of single and side-by-side finite cylinders, with a sampling frequency of 1000 Hz and a low pass filter at 300 Hz. Each data series has 2^15 elements, corresponding to a time of 32.768 s. Data obtained from digital movies of the flow visualization experiments, used to determine the influence of the flow from the top of the cylinder on the bistable phenomenon, are 159.959 s long, with 160 elements (0.999Hz sampling frequency). Hot wire data are in form of velocity series, movie data in form of distance series.
Pitch-to-diameter ratio for side-by-side cylinders was p/d = 1.26.
The aerodynamic channel was made of acrylic, with a cross section of 0.147 m x 0.193 m. The flow velocity could be varied from 0 to 15 m/s, with a turbulence intensity of about 1%. The reference velocity, measured with a Pitot tube, and the cylinder diameter, defined the Reynolds number from Red = 2.0×10^4 to Re = 2.5×10^4.
DANTEC StreamLine hot wire anemometer with two single hot wire was used. Data acquisition was made with a 16-bit A/D-board (NI 9215-A) with a USB interface using DANTEC StreamWare 3.4 software.
Flow visualizations were made in a closed-circuit hydraulic channel with the same dimensions as the aerodynamic channel, with a flow rate from 1.66×10^-6 to 1.93×10^-3 m³/s, velocities of up to 0.068 m/s and turbulence intensity of 4%. The Reynolds number was 2.0×10^3.
Data are in .txt format to be read by almost all software.

These data provide an in-sight into the long-term behaviour of tensile sutures; data were obtainedwith an experimental set up (described by Pascoletti&al in JMBBM 2020, In Press) which allowed to precisely control the tensile load applied on the suture. The suture underwent 3000 cycles between 30N and 50N; finally its residual strength was measured by means of a tensile test.
