Data collection that describes the calibration of the temporal and displacement characteristics of an optical tweezers in buffered saline at room temperature.

<p><strong>Introduction</strong>. This data provides the calibration of an optical tweezers within the linear Hookian region. Once the laser was aligned, the power at the objective measured and a bead trapped the instrument was calibrated. <strong>Data Collection</strong>. Calibration was performed by moving a trapped bead by supplying a periodic square wave train input (amplitude: &minus;800 to +800 nm, period: 80 ms) to an acousto-optical device, AOD and monitoring the trajectory of the bead in the 𝑋𝑌 plane with a quadrant photo diode, QPD for ~ one minute. Data was collected at 200 kHz from three (3) QPD channels: displacement in the 𝑋 (∆𝑋<sub>𝑀</sub>) (i) and 𝑌 directions (∆𝑌<sub>𝑀</sub>) (ii) and the sum of the fluorescent intensity (&sum;<sub>𝐿</sub>) (iii). Typically, each bead was stimulated with a train of square waves of constant amplitude in the 𝑋 direction. This stimulation was performed four (4) times at each of the different amplitudes i.e., &minus;800, +800, &minus;500, and +500 nm. The QPD signal in the dark, ∆𝑋<sub>𝐷</sub>, ∆𝑌<sub>𝐷</sub>, &sum;<sub>𝐷</sub> was recorded and subtracted in real time, and the gain, 𝐺 of the QPD noted. The Stokes-Faxen coefficient, 𝛽 was calculated having recorded the height of the bead above the Petri dish, ℎ and the viscosity, 𝜂 of the saline solution. The detected fluorescent bead was excited either with a Xenon lamp or TLED transmitted light source. Some calibrations were performed with a TLED light that was borrowed from the manufacturer for testing, and the signal to noise of these measurements was significantly decreased.<strong> Data Transformation</strong>. For each of the two (2) channels the measured signal was normalized by the sum, and the ~750 waves were averaged for each pulse train stimulus. The reciprocal of the time constant (s<sup>-1</sup>) was determined from the exponential rise or decay of the back-ground subtracted averaged response. Spring constant (pN/nm) was determined from the product of this reciprocal time constant and the Stokes-Faxen coefficient (pNs/nm). The net displacement of the bead (nm) was calculated by determining the resultant vector of the 𝑋 and 𝑌 components of the QPD (V/V). For the four (4) stimuli determined for each bead the normalized displacement (V/V) was plotted as a function of net bead displacement and the slope (V/V/nm) calculated from best linear fit. For each calibration the mean spring constant, reciprocal time constant, and mean slope are provided. <strong>Data Format</strong>. The data was saved in LabView with the proprietary TDMS format (National Instruments, NI, Austin, TX). It was transformed to a text file and imported into MATLAB (The Mathworks, Natick, MA) and stored as struct and analyzed with a Python script. The collection contains raw and transformed results from 69 days for a total 153 beads. The data is provided with annotated descriptions in HDF5, a standard non-proprietary container storage format. Each file is about 1.1 GBs (HDF5).</p> <p>&nbsp;</p> <p>The package contains:</p> <p>1. Standard Container HDF5 with custom organization format of data with annotations.</p> <p>2. Python Script (calibrateopticaltweezers.py file) that describes how data is analyzed and written to HDF5 and .MAT formats. (1 file)<br> &nbsp;</p>

Planting time data based on automated data collection

<p>In this dataset, the planting time information is based on data collected by the Risutec Asta documentation system. The data consisted of nine planting sites in western Finland (the coordinates of the study area are 60&deg;41'52"N&ndash;61&deg;59'38"N and 21&deg;36'24"E&ndash;23&deg;48'49"E). Mechanized planting was carried out by one machine entrepreneur using a crawler excavator fitted with a Risutec PM-160 planting device during the planting seasons of 2019 and 2020. A total of 72,711 seedlings were planted at the study sites (40.6 ha).&nbsp;</p> <p>&nbsp;</p> <p>The collected Asta data were used to define the time consumption and productivity of the excavator-based planting machine, considering the production time consumed at the planting worksites (hours), the loading time of the seedling cassette (minutes), the planting time per seedling (seconds), and the operating hour productivity (seedlings G<sub>15</sub>-hour<sup>&ndash;1</sup>, including short [&lt;15 min] delays). The timestamps of each mechanically planted seedlings were presented in chronological order, including the start and end times of planting work.</p> <p>&nbsp;</p> <p>The calculated planting time per seedling (s seedling<sup>&ndash;1</sup>) is presented for each planting observation (seedling). The planting time per seedling was calculated by subtracting the timestamp of the previously planted seedling from the timestamp of the planted seedling. In practice, all productivity and time consumption calculations in the study are based on the calculated planting times per seedling. Further details regarding the calculations and employed methodologies can be found in the article (Kemppainen et al. 2024).</p> <p>&nbsp;</p> <p>Description of all variables in the dataset:</p> <p>&nbsp;</p> <p>Site = Number of study site (1&ndash;9)&nbsp;</p> <p>Seedling = Order number of planted seedling</p> <p>Date = Date of planting observation (format: DD.MM.YYYY)</p> <p>Timestamp = Time of planting observation (format: HH.MM.SS)</p> <p>Planting time (s) = Calculated planting time per seedling (seconds)</p> <p>&nbsp;</p> <p>Note: In the study by Kemppainen et al.

Data from: Selection for collective aggressiveness favors social susceptibility in social spiders

Particularly socially influential individuals are present in many groups, but it is unclear whether their emergence is determined by their social influence versus the social susceptibility of others. The social spider Stegodyphus dumicola shows regional variation in apparent leader-follower dynamics. We use this variation to evaluate the relative contributions of leader social influence versus follower social susceptibility in driving this social order. Using chimeric colonies that combine potential leaders and followers, we discover that leader-follower dynamics emerge from the site-specific social susceptibility of followers. We further show that the presence of leaders increases colony survival in environments where leader-follower dynamics occur. Thus, leadership is driven by the "social susceptibility" of the population majority, rather than the social influence of key group members.

Data from: Habitat and social factors shape individual decisions and emergent group structure during baboon collective movement

For group-living animals traveling through heterogeneous landscapes, collective movement can be influenced by both habitat structure and social interactions. Yet research in collective behavior has largely neglected habitat influences on movement. Here we integrate simultaneous, high-resolution, tracking of wild baboons within a troop with a 3-dimensional reconstruction of their habitat to identify key drivers of baboon movement. A previously unexplored social influence – baboons' preference for locations that other troop members have recently traversed – is the most important predictor of individual movement decisions. Habitat is shown to influence movement over multiple spatial scales, from long-range attraction and repulsion from the troop's sleeping site, to relatively local influences including road-following and a short-range avoidance of dense vegetation. Scaling to the collective level reveals a clear association between habitat features and the emergent structure of the group, highlighting the importance of habitat heterogeneity in shaping group coordination.

Comparing and Combining Existing and Emerging Data Collection and Modeling Strategies in Support of Signal Control Optimization and Management (Project M2)

<p>For decades, traffic signal management agencies have used signal timing optimization tools combined with fine-tuning of signal timing based on field observations in their updates of time-of-day signal timing plans.&nbsp;&nbsp;These traditional signal optimization methods and tools use very limited amount of data and depend on default values in the signal timing optimization/simulation tools to estimate network performance under different signal optimization strategies. In recent years, new data collection technologies are emerging including high resolution controller data, more advanced detection technologies such as video image detection that are based on vehicle tracking and possible integration with microwave detectors, automatic-vehicle based identification technologies, third party crowdsourcing data, connected vehicles, and connected automated vehicles data.&nbsp;&nbsp;The objective of the proposed study is to propose methods and algorithms to combine data collected from existing and emerging sources with enhanced models and optimization algorithms to optimize and manage signal operations. The results from applying the developed methods and algorithms will be compared with traditional signal timing and optimization methods currently used by transportation agencies.&nbsp;</p>
