description: The bacterium Fervidibacter sacchari is an aerobic hyperthermophile that catabolizes various polysaccharides and is the only cultivated member of the class Fervidibacteria within the phylum Armatimonadota. Among its glycoside hydrolase (GH) cache is an enzyme from GH family 50 (GH50), an understudied family with only 25 characterized representatives and two known activities from 1,518 predicted members in the Carbohydrate-Active EnZyme (CAZy) Database. Here, we expressed, purified, and functionally characterized an extracellular GH50 from F. sacchari called Fsa1572. Using colorimetric assays, we show it has novel β-1,4-glucanase activity and only weak agarose activity that is typical for GH50 enzymes. The purified enzyme has a wide temperature range of 60-95 °C (optimal 80 °C), making it the first characterized hyperthermophilic representative of GH50. The enzyme also has a broad pH range of at least 5.5-11 (optimal 6.5-10). Fsa1572 possesses KM and kcat parameters of 12.6 mM and 4.62 s-1, respectively. Finally, a phylogenetic analysis of Fsa1572 and other GH50 enzymes revealed a unique phylogenetic position for Fsa1572 that is distant from other characterized enzymes and related to yet-uncharacterized GH50s from genomes of thermophilic archaea. Fsa1572 is the first characterized GH enzyme of F. sacchari and is both functionally and phylogenetically novel.

description: Ecological Momentary Assessments (EMA) are often used in the field of Psychology to deliver multiple data collection instruments to study participants at several time points in the day. As these are often used to study participants current (at the time of receiving the notification) mood, activity or immediate company, it is important that they do not anticipate the notification arrival at fixed times throughout the day. However most traditional electronic data capture (EDC) systems require participant notification schedules to be pre-determined with little to no room for sending random events individualized to participants environment (wake up time, etc.). Given this problem, our team of RSE’s has developed a cloud first random EMA notification system, that can serve 1000’s of participants multiple random EMA push notifications throughout the day. The system is capable of tracking user wake and sleep times, adapt to weekend or weekday modes and configurable to work with different randomization logic and anchors (points around which to randomize). During development the team prioritized the use of proven architectural building blocks to maximize uptime, reduce cost and speed up development. More importantly the system was built to evolve hand in hand with the changing requirements from research stakeholders. In this talk we will go over how we build this system using Amazon Web Services Event Schedulers, low cost serverless components, lessons learned from testing across various time zones, and compliance monitoring. We will look at the initial design choices, their limitations and how they had to be adapted. Finally, we will go over how the solution integrates with existing commercial EDC products such as Care Evolution’s MyDataHelps offering. The solution is currently open sourced and can be adapted by RSE teams for their own stakeholder’s studies.

description: Designing and constructing model systems that embody the statistical mechanics of frustration is now possible using nanotechnology. We have arranged nanomagnets on a two-dimensional square lattice to form an artificial spin ice, and studied its fractional excitations, emergent magnetic monopoles, and how they respond to a driving field using X-ray magnetic microscopy. We observe a regime in which the monopole drift velocity is linear in field above a critical field for the onset of motion. The temperature dependence of the critical field can be described by introducing an interaction term into the Bean-Livingston model of field-assisted barrier hopping. By analogy with electrical charge drift motion, we define and measure a monopole mobility that is larger both for higher temperatures and stronger interactions between nanomagnets. The mobility in this linear regime is described by a creep model of zero-dimensional charges moving within a network of quasi-one-dimensional objects.

description: Objective: Pediatric patients represent low frequency but potentially high-risk encounters for emergency medical services (EMS) providers. Scant information is available from EMS agencies on the frequency of pediatric skill evaluation and the presence of pediatric emergency care coordination, both which may help EMS systems optimize care for children. The objective of our study was to assess the frequency and type of methods used to assess psychomotor skills competency using pediatric-specific equipment and pediatric care coordination in EMS ground transport agencies. Methods: A web-based assessment was sent to EMS agency directors in 58 states/territories to determine the presence of pediatric care coordination defined as an individual who oversees pediatric issues (Pediatric Care Coordinator or PECC) and the process for evaluating psychomotor skills of EMS providers using of pediatric equipment. Basic demographic information of each agency was collected. Descriptive statistics, odds ratios, and 95% confidence intervals were used for analyses. Results: The response rate was 78% (8,166/10,463 agencies). Almost 80% of agencies respond to fewer than 100 pediatric calls a year; over half of the agencies are located in urban areas and provide Advanced Life Support care. Twenty-three percent (23%) of EMS agency administrators report having a PECC and 28% have plans or interest in adding one. Of those agencies with a PECC, 26% report sharing the position among several agencies. Almost half (47%) of EMS agencies evaluate pediatric psychomotor skills at least twice a year. Agencies with a PECC, those with a medium to medium high pediatric call volume and agencies located in urban areas are more likely to evaluate psychomotor skills at least twice a year. Conclusions: Although few EMS agencies currently have a PECC, there is interest among EMS agency administrators to integrate one into their system. Pediatric-specific psychomotor skills testing is more common in EMS agencies that respond to a higher pediatric call volume and have a PECC. For EMS agencies that infrequently treat children, the presence of a PECC may enhance the frequency of pediatric psychomotor skills evaluation. The presence of a PECC can potentially increase provider confidence and safety for all pediatric prehospital patients regardless of volume and location.

description: The formalism which has been developed to give general expressions for the determinants of differential operators is extended to the physically interesting situation where these operators have a zero mode which has been extracted. In the approach adopted here, this mode is removed by a novel regularisation procedure, which allows remarkably simple expressions for these determinants to be derived.

description: Introduction: There is a minimal amount of published data regarding to Emergency Medical Services (EMS) fellowship programs. The purpose of this study was to obtain program characteristics and diversity data regarding EMS fellowship programs. Methods: A survey was sent to program directors at all EMS fellowship programs accredited by the Accreditation Council of Graduate Medical Education (ACGME). Data collected included: year program started, year program accredited, unfilled fellow positions, number of EMS faculty, gender, and race/ethnicity. Gender and race/ethnicity data from EMS fellowships were compared to emergency medicine (EM) residencies using data from the American Association of Medical Colleges. Data were analyzed using IBM SPSS with descriptive statistics, and Chi-square tests. Results: The response rate for the survey was 88% (45/51) of all EMS fellowship programs that were accredited at the time of this survey. Most programs (71%) offer a one-year EMS fellowship, with the remaining offering an optional second year. The median number of physician response vehicles per program was 1.0 (IQR 0.0–2.0), with 24% (11/45) not having a dedicated physician response vehicle. This survey identified that 118 EMS fellows have graduated since inception of the accreditation process, while 34 positions went unfilled. The median number of EMS fellow positions per program was 2.0 (IQR 1.0–2.0), with a range of 1 to 4. It was noted that 31% of programs had no female EMS faculty, and 48% of programs had no under-represented minority EMS faculty. There was a significantly larger proportion of female faculty in EM residency programs (30.5%; 949/3,107) compared to EMS fellowships (19%; 53/274), OR = 1.8, 95% CI:1.3–2.5, p Conclusion: A significant number of EMS fellowship positions have remained unfilled since implementation of an accreditation process for EMS fellowships. The percentage of females and under-represented minority faculty in EMS programs was much lower than for EM residency programs.
Vortex Formation and Survival in Protoplanetary Disks subject to Vertical Shear Instability

description: Several protoplanetary disks observed by ALMA show dust concentrations consistent with particle trapping in giant vortices. The formation and survival of vortices is of major importance for planet formation, because vortices act as particle traps and are therefore preferred locations of planetesimal formation. Recent studies showed that the vertical shear instability (VSI) is capable of generating turbulence and small vortices in protoplanetary disks that have the proper radial and vertical stratification and thermally relax on sufficiently short time scales. But the effect of the azimuthal extend of the disk is often neglected as the disks azimuth is limited to $Δϕ\leq π/2$. We aim to investigate the influence of the azimuthal extent of the disk on the long-term evolution of a protoplanetary disk and the possibility of large vortices forming. To this end, we perform 3-dimensional simulations for up to 1000 local orbits using different values of $Δϕ= π/2 $ to $2π$ for VSI in disks with a prescribed radial density and temperature gradient cooling on short timescales. We find the VSI capable of forming large vortices which can exist at least several hundred orbits in simulations covering a disk with $Δϕ\geq π$. This suggests the VSI to be capable to form vortices or at least to trigger vortex formation via a secondary instability, e.g. Rossby Wave Instability or Kelvin Helmholtz Instability.

description: Infrared Imaging Spectrograph (IRIS) is the first light instrument for the Thirty Meter Telescope (TMT) that consists of a near-infrared (0.84 to 2.4 micron) imager and integral field spectrograph (IFS) which operates at the diffraction-limit utilizing the Narrow-Field Infrared Adaptive Optics System (NFIRAOS). The imager will have a 34 arcsec x 34 arcsec field of view with 4 milliarcsecond (mas) pixels. The IFS consists of a lenslet array and slicer, enabling four plate scales from 4 mas to 50 mas, multiple gratings and filters, which in turn will operate hundreds of individual modes. IRIS, operating in concert with NFIRAOS will pose many challenges for the data reduction system (DRS). Here we present the updated design of the real-time and post-processing DRS. The DRS will support two modes of operation of IRIS: (1) writing the raw readouts sent from the detectors and performing the sampling on all of the readouts for a given exposure to create a raw science frame; and (2) reduction of data from the imager, lenslet array and slicer IFS. IRIS is planning to save the raw readouts for a given exposure to enable sophisticated processing capabilities to the end users, such as the ability to remove individual poor seeing readouts to improve signal-to-noise, or from advanced knowledge of the point spread function (PSF). The readout processor (ROP) is a key part of the IRIS DRS design for writing and sampling of the raw readouts into a raw science frame, which will be passed to the TMT data archive. We discuss the use of sub-arrays on the imager detectors for saturation/persistence mitigation, on-detector guide windows, and fast readout science cases (< 1 second).

description: We present measured dielectron production cross sections for Ca+Ca, C+C, He+Ca, and d+Ca reactions at 1.0 A GeV. Statistical uncertainties and systematic effects are smaller than in previous DLS nucleus-nucleus data. For pair mass < 0.35 GeV/c2 : 1) the Ca+Ca cross section is larger than the previous DLS measurement and current model results, 2) the mass spectra suggest large contributions from pi0 and eta Dalitz decays, and 3) dsigma/dM is proportional to ApAt. For M > 0.5 GeV/c2 the Ca+Ca to C+C cross section ratio is significantly larger than the ratio of ApAt values.

Consideration of the polarizations of the produced W bosons and the beam polarizations provides substantial enhancements of the sensitivity to the Z-Z' mixing angles in various models and the asymmetry variables also give the strict constraints on the mixing angles. We find that the χ-model and the left-right model get the strict constraint from σ_{LL}^{unpol} while the ψ-model and the η-model from the beam polarization asymmetry.

description: The InfraRed Imaging Spectrograph (IRIS) is a first-light instrument for the Thirty Meter Telescope (TMT) that will be used to sample the corrected adaptive optics field by NFIRAOS with a near-infrared (0.8 - 2.4 $μ$m) imaging camera and Integral Field Spectrograph (IFS). In order to understand the science case specifications of the IRIS instrument, we use the IRIS data simulator to characterize photometric precision and accuracy of the IRIS imager. We present the results of investigation into the effects of potential ghosting in the IRIS optical design. Each source in the IRIS imager field of view results in ghost images on the detector from IRIS's wedge filters, entrance window, and Atmospheric Dispersion Corrector (ADC) prism. We incorporated each of these ghosts into the IRIS simulator by simulating an appropriate magnitude point source at a specified pixel distance, and for the case of the extended ghosts redistributing flux evenly over the area specified by IRIS's optical design. We simulate the ghosting impact on the photometric capabilities, and found that ghosts generally contribute negligible effects on the flux counts for point sources except for extreme cases where ghosts coalign with a star of $Δ$m$>$2 fainter than the ghost source. Lastly, we explore the photometric precision and accuracy for single sources and crowded field photometry on the IRIS imager.

description: A strategy developed for obtaining positive cellular responses remains to be focused in the filed of functional biomimetics. In this study, a hydrogel covered simvastatin-loaded polyetheretherketone (PEEK) bio-composites was constructed with the purpose of bone tissue regeneration therapy. Briefly, a three-dimensional (3D) porous structure was fabricated on PEEK surface; then the substrate was functionalized with the poly(L-lactic acid)/simvastatin porous film and hyaluronic acid hydrogel subsequently. In vitro cell attachment, proliferation, and cytoskeletal observation experiments reveal that our scaffolds show better bio-affinity due to the layer of hyaluronic acid hydrogel compared with control. Furthermore, the alkaline phosphatase activity, calcium mineral deposition evaluation, and gene expression for osteogenic potential all exhibit that the superior osteogenic differentiation of MC3T3-E1 pre-osteoblasts on our scaffolds. Therefore, our PEEK samples loaded with simvastatin and covered with hyaluronic acid hydrogel hold great potential in clinical applications for bone repair.

description: In light of the energetic crisis and the urgent need for the decarbonization of industries, technologies such as water electrolysis for hydrogen production have attracted greater attention. This technology has been demonstrated to be a potential and sustainable solution to cope with the energy demand while reducing greenhouse gas (GHG) emissions when utilizing low-carbon sources such as renewable energy. Therefore, it is crucial to assess the availability of water sources and their treatment methods for this future scenario. Seawater is one of the most abundant water sources, which makes it a promising alternative for this process. However, it contains high concentrations of salt, minerals, and other impurities, limiting its versatility. In this vein, researchers have investigated different membrane filtration technologies, such as reverse osmosis (RO), membrane distillation (MD), and electrodialysis (ED), to obtain high-purity water complying with the minimum requirements of the American Society for Testing and Materials (ASTM) Type II deionized water. The purification process consists of running seawater through a semi-permeable membrane that allows water molecules to pass through while blocking larger molecules such as salt and other impurities. Overall, membrane-based applications can be practical for seawater desalination as a water electrolysis and H2 production resource. However, it is important to note that membrane technology also has some disadvantages, such as fouling, being energy-intensive, and the cost of the process can vary depending on the conditions, type of membrane, and specific requirements and applications. Therefore, it is essential to carefully study and consider its cost and energy requirements as well as its social and environmental impact before implementing this strategy. This study reviews the possible performance of the technology, helping to reduce the need for freshwater resources, its challenges, and the possible upgrades to improve the sustainability of the process.
Bubble-nucleation rates for radiatively induced first-order phase transitions

description: We present a consistent calculation of bubble-nucleation rates in theories of two scalar fields. Our approach is based on the notion of a coarse-grained free energy that incorporates the effects of fluctuations with momenta above a given scale k. We establish the reliability of the method for a variety of two-scalar models and confirm the conclusions of previous studies in one-field theories: Langer's theory of homogeneous nucleation is applicable as long as the expansion around the semiclassical saddle point associated with tunnelling is convergent. This expansion breaks down when the exponential suppression of the rate by the saddle-point action becomes comparable to the pre-exponential factor associated with fluctuations around the saddle point. We reconfirm that Langer's theory is not applicable to the case of weakly first-oder phase transitions. We also find that the same is true in general for radiatively induced first-order phase transitions. We discuss the relevance of our results for the electroweak phase transition and the metastability bound on the Higgs-boson mass.

description: Aims. Historical records provide evidence of extreme magnetic storms with equatorward auroral extensions before the epoch of systematic magnetic observations. One significant magnetic storm occurred on February 15, 1730. We scale this magnetic storm with auroral extension and contextualise it based on contemporary solar activity. Methods. We examined historical records in East Asia and computed the magnetic latitude (MLAT) of observational sites to scale magnetic storms. We also compared them with auroral records in Southern Europe. We examined contemporary sunspot observations to reconstruct detailed solar activity between 1729 and 1731. Results. We show 29 auroral records in East Asian historical documents and 37 sunspot observations. Conclusions. These records show that the auroral displays were visible at least down to 25.8° MLAT throughout East Asia. In comparison with contemporary European records, we show that the boundary of the auroral display closest to the equator surpassed 45.1° MLAT and possibly came down to 31.5° MLAT in its maximum phase, with considerable brightness. Contemporary sunspot records show an active phase in the first half of 1730 during the declining phase of the solar cycle. This magnetic storm was at least as intense as the magnetic storm in 1989, but less intense than the Carrington event.

Pion dispersion relation at finite temperature in the linear sigma model from chiral Ward identities

description: We develop one-loop effective vertices and propagators in the linear sigma model at finite temperature satisfying the chiral Ward identities. We use these in turn to compute the pion dispersion relation in a pion medium for small momentum and temperatures on the order of the pion mass at next to leading order in the parameter m_pi^2/4pi^2f_pi^2 and to zeroth order in the parameter (m_pi/m_sigma)^2. We show that this expansion reproduces the result obtained from chiral perturbation theory at leading order. The main effect is a perturbative, temperature-dependent increase of the pion mass. We find no qualitative changes in the pion dispersion curve with respect to the leading order behavior in this kinematical regime.

description: Analysing the kinematics of filamentary molecular clouds is a crucial step towards understanding their role in the star formation process. Therefore, we study the kinematics of 283 filament candidates in the inner Galaxy, that were previously identified in the ATLASGAL dust continuum data. The $^{13}$CO(2 - 1) and C$^{18}$O(2 - 1) data of the SEDIGISM survey (Structure, Excitation, and Dynamics of the Inner Galactic Inter Stellar Medium) allows us to analyse the kinematics of these targets and to determine their physical properties at a resolution of 30 arcsec and 0.25 km/s. To do so, we developed an automated algorithm to identify all velocity components along the line-of-sight correlated with the ATLASGAL dust emission, and derive size, mass, and kinematic properties for all velocity components. We find two-third of the filament candidates are coherent structures in position-position-velocity space. The remaining candidates appear to be the result of a superposition of two or three filamentary structures along the line-of-sight. At the resolution of the data, on average the filaments are in agreement with Plummer-like radial density profiles with a power-law exponent of p = 1.5 +- 0.5, indicating that they are typically embedded in a molecular cloud and do not have a well-defined outer radius. Also, we find a correlation between the observed mass per unit length and the velocity dispersion of the filament of $m \sim σ_v^2$. We show that this relation can be explained by a virial balance between self-gravity and pressure. Another possible explanation could be radial collapse of the filament, where we can exclude infall motions close to the free-fall velocity.

Breakup Temperature of Target Spectators in Au + Au Collisions at E/A = 1000 MeV

description: Breakup temperatures were deduced from double ratios of isotope yields for target spectators produced in the reaction Au + Au at 1000 MeV per nucleon. Pairs of $^{3,4}$He and $^{6,7}$Li isotopes and pairs of $^{3,4}$He and H isotopes (p, d and d, t) yield consistent temperatures after feeding corrections, based on the quantum statistical model, are applied. The temperatures rise with decreasing impact parameter from 4 MeV for peripheral to about 10 MeV for the most central collisions. The good agreement with the breakup temperatures measured previously for projectile spectators at an incident energy of 600 MeV per nucleon confirms the observed universality of the spectator decay at relativistic bombarding energies. The measured temperatures also agree with the breakup temperatures predicted by the statistical multifragmentation model. For these calculations a relation between the initial excitation energy and mass was derived which gives good simultaneous agreement for the fragment charge correlations. The energy spectra of light charged particles, measured at $θ_{lab}$ = 150$^{\circ}$, exhibit Maxwellian shapes with inverse slope parameters much higher than the breakup temperatures. The statistical multifragmentation model, because Coulomb repulsion and sequential decay processes are included, yields light-particle spectra with inverse slope parameters higher than the breakup temperatures but considerably below the measured values. The systematic behavior of the differences suggests that they are caused by light-charged-particle emission prior to the final breakup stage. PACS numbers: 25.70.Mn, 25.70.Pq, 25.75.-q

description: A multi-objective model for managing railway infrastructure asset renewal is presented. The model aims to optimize three objectives, while respecting operational constraints: levelling investment throughout multiple years, minimizing total cost and minimizing work start postponements. Its output is an optimized intervention schedule. The model is based on a case study from a Portuguese infrastructure management company, which specified the objectives and constraints, and reflects management practice on railway infrastructure. The results show that investment levelling greatly influences the other objectives and that total cost fluctuations may range from insignificant to important, depending on the condition of the infrastructure. The results structure is argued to be general and suggests a practical methodology for analysing trade-offs and selecting a solution for implementation.

description: We investigate the kinetics of constant-kernel aggregation which is augmented by either: (a) evaporation of monomers from finite-mass clusters, or (b) continuous cluster growth -- \ie, condensation. The rate equations for these two processes are analyzed using both exact and asymptotic methods. In aggregation-evaporation, if the evaporation is mass conserving, \ie, the monomers which evaporate remain in the system and continue to be reactive, the competition between evaporation and aggregation leads to several asymptotic outcomes. For weak evaporation, the kinetics is similar to that of aggregation with no evaporation, while equilibrium is quickly reached in the opposite case. At a critical evaporation rate, the cluster mass distribution decays as $k^{-5/2}$, where $k$ is the mass, while the typical cluster mass grows with time as $t^{2/3}$. In aggregation-condensation, we consider the process with a growth rate for clusters of mass $k$, $L_k$, which is: (i) independent of $k$, (ii) proportional to $k$, and (iii) proportional to $k^μ$, with $0

description: A canonical ensemble model is used to describe a caloric curve of nuclear liquid-gas phase transition. Allowing a discontinuity in the freeze out density from one spinodal density to another for a given initial temperature, the nuclear liquid-gas phase transition can be described as first order. Averaging over various freeze out densities of all the possible initial temperatures for a given total reaction energy, the first order characteristics of liquid-gas phase transition is smeared out to a smooth transition. Two experiments, one at low beam energy and one at high beam energy show different caloric behaviors and are discussed.
