Do Carefully-timed Email Messages Increase Accuracy and Precision in Citizen Scientists' Reports of Events?

Periodic messages are a commonly used tactic for reminding citizen science program participants to take a desired action such as collecting observations. In this study, we evaluate the impact of such messages on the accuracy and precision of observations contributed to Nature’s Notebook, a citizen science phenology observing program. To encourage participants in Nature’s Notebook to log the timing of leaf-out and flowering with maximum accuracy and precision, we email observers three days prior to when the events were expected to occur based on forecast models. Unplanned interruptions to the scripts driving these email prompts allowed us to evaluate whether the messages had the intended impacts.

Dual spring force couples yield multifunctionality and ultrafast, precision rotation in tiny biomechanical systems

Small organisms use propulsive springs rather than muscles to repeatedly actuate high acceleration movements, even when constrained to tiny displacements and limited by inertial forces. Through integration of a large kinematic dataset, measurements of elastic recoil, energetic math modeling, and dynamic math modeling, we tested how trap-jaw ants (Odontomachus brunneus) utilize multiple elastic structures to develop ultrafast and precise mandible rotations at small scales. We found that O. brunneus develops torque on each mandible using an intriguing configuration of two springs: their elastic head capsule recoils to push and the recoiling muscle-apodeme unit tugs on each mandible. Mandibles achieved precise, planar, circular trajectories up to 49,100 radians/sec (470,000 rpm) when powered by spring propulsion. Once spring propulsion ended, the mandibles moved with unconstrained and oscillatory rotation. We term this mechanism "dual spring force couple" meaning that two springs deliver energy at two locations to develop torque. Dynamic modeling revealed that dual spring force couples reduce the need for joint constraints and thereby reduce dissipative joint losses, which is essential to the repeated use of ultrafast, small systems. Dual spring force couples enable multifunctionality: trap-jaw ants use the same mechanical system to produce ultrafast, planar strikes driven by propulsive springs and for generating slow, multi-degree of freedom mandible manipulations using muscles, rather than springs, to directly actuate the movement. Dual spring force couples are found in other systems and are likely widespread in biology. These principles can be incorporated into microrobotics to improve multifunctionality, precision, and longevity of ultrafast systems.

Precision synthesis of reducing-end thiol-modified cellulose enabled by enzyme selection

We provide here the underlying data of the publication "Precision synthesis of reducing-end thiol-modified cellulose enabled by enzyme selection". Please find the abstract below. Enzyme-catalyzed iterative β-1,4-glycosylation of β-glycosides is promising for bottom-up polymerization of reducing-end-modified cello-oligosaccharide chains. Self-assembly of the chains from solution yields crystalline nanocellulose materials with properties that are tunable by the glycoside group used. Cellulose chains with a reducing-end thiol group are of interest to install a controllable pattern of site-selective modifications into the nanocellulose material. Selection of the polymerizing enzyme (cellodextrin phosphorylase; CdP) was pursued here to enhance the synthetic precision of β-1-thio-glucose conversion to generate pure “1-thio-cellulose” (≥95%) unencumbered by plain (unlabeled) cellulose resulting from enzymatic side reactions. The CdP from Clostridium stercorarium (CsCdP) was 21 times more active on β-1-thio-glucose (0.17 U/mg; 45 °C) than the CdP from Clostridium cellulosi (CcCdP), and it lacked hydrolase activity, which is substantial in CcCdP, against the α-D-glucose 1-phosphate donor substrate. The combination of these enzyme properties indicated that CsCdP is a practical catalyst for 1-thio-cellulose synthesis directly from β-1-thio-glucose (8 h; 25 mol% yield) that does not require a second enzyme (cellobiose phosphorylase), which was essential when using the less selective CcCdP. The 1-thio-cellulose chains had an average degree of polymerization of &sim;10 and were assembled into highly crystalline cellulose II crystallinity material.

Data from: SimPLE: A visuotactile method learned in simulation to precisely pick, localize, regrasp, and place objects

Existing robotic systems have a clear tension between generality and precision. Deployed solutions for robotic manipulation tend to fall into the paradigm of one robot solving a single task, lacking precise generalization, i.e., the ability to solve many tasks without compromising on precision. This paper explores solutions for precise and general pick-and-place. In precise pick-and-place, i.e. kitting, the robot transforms an unstructured arrangement of objects into an organized arrangement, which can facilitate further manipulation. We propose simPLE (simulation to Pick Localize and PLacE) as a solution to precise pick-and-place. simPLE learns to pick, regrasp and place objects precisely, given only the object CAD model and no prior experience. We develop three main components: task-aware grasping, visuotactile perception, and regrasp planning. Task-aware grasping computes affordances of grasps that are stable, observable, and favorable to placing. The visuotactile perception model relies on matching real observations against a set of simulated ones through supervised learning. Finally, we compute the desired robot motion by solving a shortest path problem on a graph of hand-to-hand regrasps. On a dual-arm robot equipped with visuotactile sensing, we demonstrate pick-and-place of 15 diverse objects with simPLE. The objects span a wide range of shapes and simPLE achieves successful placements into structured arrangements with 1mm clearance over 90% of the time for 6 objects, and over 80% of the time for 11 objects.

VELOCE I. High-precision Radial Velocities of Cepheids

The first data release of the VELOcities of CEpheids project (VELOCE DR1, Anderson et al. 2024, A&A in press, arXiv: 2404.12280, doi: <a href="https://doi.org/10.1051/0004-6361/202348400">10.1051/0004-6361/202348400</a>) comprises 18,225 radial velocity measurements (RVs) of 258 bona-fide classical Cepheids as well as 1161 RVs of 164 additional targets, most of which were previously misclassified as Cepheids. The observations were collected mainly between 2010 and 2022 using two 1.2m telescopes: Euler (Coralie spectrograph) at ESO La Silla Observatory in Chile, and  Mercator (Hermes spectrograph) at Roque de los Muchachos Observatory on La Palma, Canary Islands, Spain.  Here, we publish the FITS files as described in appendix C of VELOCE paper I (Anderson et al. 2024). A total of 422 FITS files -- one per star -- are compressed together using tar and gzip as they would otherwise exceed the limit of 100 files in Zenodo. The FITS files contain all 19,386 individual RV measurements, as well as the per-epoch template fit residuals used to measure zero-point offsets and investigate long-term orbital motion.

Data from Churan et al. 2018 Comparison of the precision of smooth pursuit in humans and head unrestrained monkeys

Experiments were performed in two rhesus monkeys, B and E. Each monkey made a combination of slow and fast eye-movements following a visual target. The target was stationary at first and then either abruptly started moving (at a speed of 10°/s) in a certain direction (Ramp paradigm) or made a Step before starting the motion (Step-Ramp paradigm). By using a specific Step size and Step direction the initial saccade was eliminated in the Step-Ramp paradigm. The direction of the stimulus motion was predominantly horizontal with a smaller vertical component that was systematically varied between 0° and +-20°. We investigated how precisely the monkeys can follow this vertical component of the stimulus motion. The files: There are separate files for each monkey (B and E) and paradigm (Ramp and Step_Ramp). The files are MATLAB data files. Ramp: Each file consists of three variables – ‘alldatx’, ‘alldaty’, and ‘init’. ‘alldatx’ and ‘alldaty’ are cell arrays in which each cell represents one vertical component of the stimulus: 1=20° up, 2=10° up, 3=5° up, 4=2° up, 5=0° , 6=2° down, 7=5° down, 8=10° down, 9=20° down. Each cell contains a matrix of n x 2001 elements. Each row represents the eye velocities during one individual trial between 1000 ms before and 1000 ms after the start of stimulus motion with a sampling rate of 1000 Hz. ‘init’ is a cell array in which each cell represents one vertical component of the stimulus (s. above). Each cell contains a structure array which shows the approximate properties of the initial saccade in each trial: ‘init.t’: Start end end time of the saccade (in ms) after the start of stimulus motion. ‘init.amp’: Amplitude of the initial saccade in deg ‘init.startpos’, ‘init.endpos’: start- and end-position (x, y) of the saccade Step_Ramp: Each file consists of two variables – ‘alldatx’, ‘alldaty’. Description is the same as for Ramp.
