title: Sonification of the atmospheric carbon record over the past 800,000 years

description: This piece is part of a collection of sound compositions called
 Timescales, which sonifies datasets spanning different time scales of the
 atmospheric carbon record. Glaciations is a musical sonification of
 atmospheric carbon dioxide inferred from ice cores, from 800,000 years ago
 to the present. This scale encompasses the small shifts in earth’s orbit
 which drove the rise and fall of eight successive ice ages and alternating
 warm periods. The intention behind the compositional choices in this
 composition is to evoke a sense of vastness and wonder, and to create a
 sonic landscape of planetary motion and deep time.
description: Glacial cycles are the central organizing
 feature of this composition. Historical time is linearly mapped to musical
 time: one beat in musical time represents 2,000 years. The carbon record
 is mapped to a pentatonic scale spanning six octaves, with 170 ppm and 420
 ppm at the lower and upper limits, respectively, of
 CO<sub>2</sub> measurements.  A simple sine wave tone glides up and down to
 sonify CO<sub>2</sub>. Three additional longer sonic layers
 rise and swell with each successive interglacial warm period, all using FM
 synthesis. One layer is a beating sound, with three or four beats per data
 point. The carrier frequency of this sound is set by the first value of
 CO<sub>2</sub> in the cycle, and stays constant for the
 duration of the cycle.  A second layer is sustained over three data
 points, or approximately 6,000 historical years. This sound is created
 with complex modulation FM synthesis. The carrier frequency is one octave
 below the CO<sub>2</sub> value.  A third sound is held over
 the duration of the whole glacial cycle. This is made with a complex
 carrier frequency set, as with the first layer, by the first
 CO<sub>2</sub> value in the cycle.  The final data point, which represents the
 present-day CO<sub>2</sub> value, is held longer than the
 others, and fades away. This was an aesthetic choice not to cut off the
 sound too abruptly, but allow the high frequency. It is almost a comical
 sound in contrast to the rest of the piece, intentionally
 disjointed.  Carbon Dioxide Records

title: Data from: Cryptic male mate choice for high-quality females reduces male postcopulatory success in future matings

description: Cryptic male mate choice occurs when males differentially allocate
 resources to females during or after copulation. When male resources are
 limited, males may benefit by strategically allocating more resources
 toward higher-quality females. In the fruit fly, Drosophila
 melanogaster, males mate for longer and may transfer more sperm and more
 seminal proteins when they mate with larger females compared to smaller
 females. It is unclear, however, whether this increased investment in
 large females has any impact on the males’ later matings. We
 mated D. melanogaster males sequentially to females of
 large or small body size in all possible combinations to test
 whether cryptic male mate choice for large females is costly to the males’
 subsequent matings. Second matings were shorter for males compared to
 their first matings, but there were no differences in fecundity between
 females mated first or second by a male. Interestingly,
 male success at defensive sperm competition declined between his
 first and second matings only when his first mating had been with a large
 female. This suggests that the higher initial
 investment in large females reduced male postcopulatory success
 in their subsequent matings. Cryptic male mate choice may carry
 underappreciated costs to males that could limit their reproductive
 potential.

title: Data from: N-dimensional hypervolumes in trait-based ecology: does occupancy rate matter?

description: Many methods for estimating functional diversity of biological communities
 rely on measuring geometrical properties of n-dimensional hypervolumes in
 a trait space. To date, these properties are calculated from individual
 hypervolumes or from their pairwise combinations. Our capacity to detect
 functional diversity patterns due to the overlap of multiple hypervolumes
 is thus limited. Here, we propose a new approach for estimating functional
 diversity from a set of hypervolumes. We rely on the concept of occupancy
 rate, defined as the mean or absolute number of hypervolumes enclosing a
 given point in the trait space. Furthermore, we describe a permutation
 test to identify regions of the trait space in which the occupancy rate of
 two sets of hypervolumes differs. We illustrate the utility of our
 approach over existing methods with two examples on aquatic
 macroinvertebrates. The first example shows how occupancy rate relates to
 the stability of trait space utilisation due to increased flow
 intermittency and allows the identification of taxa in regions of the
 trait space with low occupancy rates. The second example shows how the
 permutation test based on occupancy rates can detect differences in trait
 space utilisation due to river morphology variation even with a high
 degree of overlap among input hypervolumes. Our newly developed approach
 is particularly suitable in functional diversity analysis when
 investigating patterns of overlap among multiple hypervolumes. We thus
 emphasise the need to consider analyses based on occupancy rate into
 functional diversity estimation.

title: 3D printing template for The Water-Exclusion Trap (WET): A 3D printable window trap collector that prevents DNA degradation

description: 3D templates of a long-term storable bottom collector for window or
 pitfall traps. The collection medium in a LEE trap barely evaporates and
 does not dilute because water is excluded, maximizing DNA preservation.
 Based on field-collected specimens and lab experiments, we confirm that
 the LEE significantly outperforms conventional traps in terms of DNA
 quality.

title: Data from: Environmental DNA metabarcoding revealed the impacts of anthropogenic activities on phytoplankton diversity in Dianchi Lake and its three inflow rivers

description: Phytoplankton diversity is closely related to environmental
 variables and has been widely used in ecological health
 assessment of rivers and lakes. Combining the advantages of
 DNA-based identification and high-throughput sequencing technology,
 environmental DNA (eDNA) metabarcoding permits a new measurement
 for biodiversity monitoring in aquatic ecosystems. However, it had rarely
 been used to explore the variability and similarity of
 phytoplankton diversity between a lake and its
 inflow rivers and the effects of environmental variables on
 phytoplankton. This study utilized eDNA metabarcoding to
 investigate the spatial distribution of phytoplankton and the
 impacts of environmental variables on the phytoplankton diversity
 in Dianchi Lake (one of the most polluted urban lakes in China) and its
 main inflow rivers (Panlong River, Baoxiang River and Chai
 River).  The OTU table is  the original table about
 phytoplankton taxa. A total of 243 distinct phytoplankton taxa were
 detected, covering 9 phyla, 30 classes, 84 orders and
 132 families, and the taxonomic richness of rivers was higher
 than that of Dianchi Lake.

title: Monte Carlo simulation of water cylinder phantoms for Data Driven Gating (DDG) in single photon emission tomography

description: Objective: Multiple different algorithms have been proposed for Data
 Driven Gating (DDG) in Single Photon Emission Computed Tomography (SPECT)
 and have successfully been applied to Myocardial Perfusion Imaging (MPI).
 Application of DDG to acquisition types other than SPECT MPI has not been
 demonstrated so far, as the limitations and pitfalls of current methods
 are unknown. Approach: We create a comprehensive set of phantoms that
 allow the characterization of DDG algorithms and perform Monte Carlo
 simulations, simulating the influence of different motion artifacts, view
 angles, moving feature diameters, contrasts, and count levels. We derive
 quantitative metrics from the data and evaluate the Center of Light (COL)
 and Laplacian Eigenmaps (LE) methods as sample DDG algorithms. Main
 results: View angle, feature size, count rate density, and contrast
 influence the accuracy of both DDG methods. Moreover, the ability to
 extract the respiratory motion in the phantom was shown to correlate with
 the contrast of the moving feature to the background, the Signal to Noise
 ratio, and the noise in the data. Significance: We showed that reporting
 the average correlation to an external physical reference signal per
 acquisition is not sufficient to characterize DDG methods. Assessing DDG
 methods on a view-by-view basis using the simulations and metrics from
 this work could enable the identification of pitfalls of current methods,
 and extend their application to acquisitions beyond SPECT MPI.

title: Dung beetle community composition affects dung turnover in subtropical US grasslands

description: Dung beetle community data were collected from August 2018 – March 2023 on
 three ranches; Buck Island Ranch, Durando Ranch and Longino Ranch in
 Florida, USA. Traps were baited with either chicken feet (trap type c), or
 dung in balls wrapped in muslin (trap type b) or dung placed directly on a
 pitfall trap (trap type a). Sample sites that had greater than 20% tree
 canopy cover were classed as 'closed' and 'open' if in
 open pasture or if the sample site had less than 20% tree canopy
 cover.

title: Passively Addressed Robotic Morphing Surface (PARMS) based on machine learning

description: Reconfigurable morphing surfaces provide new opportunities for advanced
 human-machine interfaces and bio-inspired robotics. Morphing into
 arbitrary surfaces on demand requires a device with a sufficiently large
 number of actuators and an inverse control strategy that can calculate the
 actuator stimulation necessary to achieve a target surface. The
 programmability of a morphing surface can be improved by increasing the
 number of independent actuators, but this increases the complexity of the
 control system. Thus, developing compact and efficient control interfaces
 and control algorithms is a crucial knowledge gap for the adoption of
 morphing surfaces in broad applications. In this work, we describe a
 passively addressed robotic morphing surface (PARMS) composed of
 matrix-arranged ionic actuators. To reduce the complexity of the physical
 control interface, we introduce passive matrix addressing. Matrix
 addressing allows the control of N2 independent actuators using only 2N
 control inputs, which is significantly lower than N2 control inputs
 required for traditional direct addressing. Our control algorithm is based
 on machine learning using finite element simulations as the training data.
 This machine-learning approach allows both forward and inverse control
 with high precision in real time. Inverse control demonstrations show that
 the PARMS can dynamically morph into target surfaces on demand. These
 innovations in actuator matrix control may enable future implementation of
 PARMS in wearables, haptics, and augmented reality/virtual reality
 (AR/VR).
description: The dataset include the point cloud data of every experiment in
 forward and inverse control and the pre-trained ML model based on
 simulation data. Also, it includes the raw data in single strip and system
 characterization.  The point cloud data in .txt file
 can be processed by either Matlab or Python. The pre-trained ML model
 (they are .m files but not for Matlab) can be used by Python directly to
 generate the input voltage array (inverse control) or z-displacement array
 (forward control) The raw data of single strip actuator
 and system characterization are in .txt and .csv files. They can be
 reproduced by Matlab.
description: The .m files in ML data are pre-trained ML model which should be
 used by Python, not Matlab. The other data files are in .txt or .csv
 format. Either Matlab or Python can open them.

title: Sacramento River RAFT water temperature model simulations based on hypothetical reservoir perturbations in the historical record

description: We used a process-based water temperature model (RAFT, Pike et al., 2013)
 to estimate the ability of reservoir discharge to mediate river
 temperature heating processes impacting downstream locations (i.e.,
 discharge-mediated temperature management) on California's Sacramento
 River. This was done by modeling water temperatures over the historical
 record (1990-2020) of model forcings and only perturbing reservoir
 discharge levels on a daily time step, ranging from 3000 to 15000 cubic
 feet per second as simulated at the Sacramento River at Wilkins Slough

title: Pre-Younger Dryas megafaunal extirpation at Rancho La Brea linked to fire-driven state shift

description: The cause, or causes, of the Pleistocene megafaunal extinctions have been
 difficult to establish, in part because poor spatiotemporal resolution in
 the fossil record prevents alignment of species disappearances with
 archeological and environmental datasets. We obtained 172 new radiocarbon
 dates on megafauna from Rancho La Brea, USA, spanning 15.6 to 10 thousand
 calendar years before present (ka). Seven species of extinct megafauna
 disappeared by 13 ka, before the onset of the Younger Dryas. Comparison
 with high-resolution regional datasets reveals these disappearances
 coincided with an ecological state shift that followed aridification and
 vegetation changes during the Bølling-Allerød. Time series modeling
 implicates large-scale fires caused by humans as the primary cause of the
 extirpations; the catalyst of this state shift appears to have been
 mounting human impacts in a drying, warming, and increasingly fire-prone
 ecosystem.

title: Electric field and conductivity measurements in the stratosphere

description: This dataset is a compressed archive that includes 2 data files in binary
 format, 4 files in csv format, and 2 metadata files (pdf documents) that
 provide information on how to interpret the data. This data was collected
 from instruments deployed on two stratospheric balloons, launched a day
 apart in late June 2021 from central Oregon. They flew on upper level
 winds to the west, out over the northeastern Pacific Ocean. The
 measurement objective was a multi-day set of vertical electric field and
 polar conductivity measurements at roughly a 10 minute cadence, and from
 widely separated locations in the stratosphere. The binary format data is
 comprehensive, including everything that was measured. The csv files have
 been processed from the raw data files into calibrated, timed, and
 time-ordered ASCII files containing the primary science measurements and
 some essential auxiliary measurements such as measurement location and
 time. This data was collected in an effort to (1) compare the fair-weather
 return current density at different geographic locations and (2) to
 compare the fair-weather current density with global thunderstorm
 activity.
description: Data was collected from two balloons in the stratosphere, mostly
 over the Pacific ocean, via Iridium SBD modems included in each payload.
 Science instruments are vertical double Langmuir probes on booms attached
 to a central payload. This measurement technique has been in use for
 several decades. Both the raw and processed data are included in this
 archive. Accompanying documentation describes the unprocessed binary data
 and the ASCII files of processed data. The L1 (processed data) consists of
 time, location, vertical electric field, and polar conductivity
 measurements from the two balloon payloads.
description: The unprocessed L0 is in binary fixed format records, and
 requires programming effort to extract and interpret the data. The
 processed L1 data is in ASCII format, and requires no special software to
 interpret. The included documentation provides sufficient detail to
 interpret all of the data. The documentation includes information on the
 limitations of the data, such as the fact that sunlight increases the
 apparent positive ion conductivity through photo-electron
 emission.

title: Data from: Why do endothermic vertebrates have bigger brains than ectothermic ones?

description: Endothermic vertebrates (birds and mammals) show much larger relative
 brain sizes than ectothermic ones. The gap is widely attributed to the
 evolution of endothermy itself, which makes sustained high body
 temperatures possible. However, other variables that emerged or
 proliferated after endothermy arose, in particular greater and more
 extended parental provisioning, no doubt also contribute to this
 gap. Here, we conducted a targeted comparison of lizards and
 precocial birds to estimate the relative contribution of these factors.
 Both taxa share large amniotic eggs, lack post-hatching provisioning, and
 have overlapping body temperatures. After statistically removing
 additional confounding variables, we found that the statistical effect of
 endothermy amounts to a near-tripling of brain size, and thus accounts for
 about half of the difference in brain size between lizards and birds in
 general. A separate analysis revealed that the effect of extended parental
 provisioning in birds is associated with a near-doubling of brain size.
 These results suggest that various processes that were enabled or
 facilitated by endothermy, in particular parental provisioning after
 hatching or birth, played an equally important role in the evolution of
 increased brain size among endotherms.

title: Data for: Non-linear optical phonon spectroscopy revealing polaronic signatures of the LaAlO3/SrTiO3 interface

description: We report the direct observation of lattice phonons confined at
 LaAlO3/SrTiO3 (LAO/STO) interfaces and STO surfaces using the
 sum-frequency phonon spectroscopy. This interface-specific nonlinear
 optical technique unveiled phonon modes localized within a few monolayers
 at the interface, with inherent sensitivity to the coupling between
 lattice and charge degrees of freedom. Spectral evolution across the
 insulator-to-metal transition at LAO/STO interface revealed an electronic
 reconstruction at the sub-critical LAO thickness, as well as strong
 polaronic signatures upon formation of the two-dimensional electron gas.
 We further discovered a characteristic lattice mode from interfacial
 oxygen vacancies, enabling us to probe such important structural defects
 in situ. Our study provides a new perspective on many-body interactions at
 the correlated oxide interfaces.
