description: We present a highly reflective, sub-wavelength-thick membrane resonator featuring high mechanical quality factor and discuss its applicability for cavity optomechanics. The $88.5~\text{nm}$ thin stoichiometric silicon-nitride membrane, designed and fabricated to combine 2D-photonic and phononic crystal patterns, reaches reflectivities up to $99.89~\%$ and a mechanical quality factor of $2.9 \times 10^7$ at room temperature. We construct a Fabry-Perot-type optical cavity, with the membrane forming one terminating mirror. The optical beam shape in cavity transmission shows a stark deviation from a simple Gaussian mode-shape, consistent with theoretical predictions. We demonstrate optomechanical sideband cooling to mK-mode temperatures, starting from room temperature. At higher intracavity powers we observe an optomechanically induced optical bistability. The demonstrated device has potential to reach high cooperativities at low light levels desirable for e.g. optomechanical sensing and squeezing applications or fundamental studies in cavity quantum optomechanics, and meets the requirements for cooling to the quantum ground state of mechanical motion from room temperature.

The development and evaluation of a contractile, hydrogel scaffold for skeletal muscle tissue engineering
Creators: name: Khalili, Amin
Publisher: name: No Publisher Supplied
Year: 2020

description: Skeletal muscle tissue has the ability to regenerate and return function to the damaged areas following an incident that has resulted in muscle loss or injury. However, in severe injuries with large volumetric deficiencies, body’s natural healing mechanisms fall short and require artificial interventions. There currently exist surgical treatments such as muscle flaps to promote healing and help damaged skeletal muscle tissue to return to their functional state. However, such treatments have significant drawbacks and often lead to a lowered quality life for patients. The field of tissue engineering has demonstrated preliminary advances through the use of three-dimensional scaffolds as a solution to develop a personalized treatment for volumetric muscle loss. Despite such advances in this field, there remains an abundant of hurdles before scaffolds can become widely used in clinical setting. Recently tissue engineers have been successful to design skeletal muscle scaffolds that led to the fusion of myoblasts into myotubes, however, the lack of electrical and mechanical stimuli similar to the native tissue can prevent the formation of functional muscle. The overall goal of this research project is to develop polymeric scaffolds to deliver the necessary stimuli to form functional skeletal muscles. Herein, Poly(ethylene glycol) diacrylate (PEGDA) has been copolymerized with MAETAC to form an electroactive polymer, that can change size or shape as a response to an electric field, has been combined with PEDOT:PSS to develop a skeletal muscle tissue engineering scaffold. To that end, this project has the following aims: 1) Characterize and optimize a positively charged poly(ethylene glycol) diacrylate based hydrogel as an actuating muscle tissue engineering scaffold; 2) Develop and optimize an electroconductive self-actuating multilayer scaffold for skeletal muscle tissue engineering.

description: One technique, which has recently emerged from the study of how probabilities and payoffs determine the attractiveness of a gamble, is the use of duplex bets. Systematic and independent manipulation of the gambles' components is possible, within the context of risky decision making, permitting assessment of the contribution that each component makes in the gambles' evaluation. The influence of each risk dimension was inferred from the attractiveness ratings that a sample of 20 recidivists, from a London prison, made for a series of duplex bets.
TEACHING WITH INQUIRY: SOCIAL STUDIES INSTRUCTIONAL STRATEGIES THAT FOSTER THE CIVIC READINESS OF MIDDLE GRADERS

Publisher: name: Purdue University Graduate School
Year: 2023
Subjects: Curriculum and pedagogy theory and development

description: The decline in Americans’ civic knowledge and engagement is alarming and concerning for U.S. democracy. Over the years, there has been an increasing concern about the amount of civic knowledge and content taught in schools, students’ civic scores, equipping classrooms with civic learning opportunities, and federal funding for students in civics and civic programs. Thus, extant literature shows four critical gaps of concern: 1) curriculum gap, 2) knowledge gap, 3) research gap, and 4) funding gap. As a result, studies on civic readiness have become essential due to the growing concern for reinforcing civic readiness in U.S. classrooms. However, despite the National Council for the Social Studies (NCSS) advocacy for inquiry as the best practice for social studies teaching and using the Inquiry Design Model (IDM) in teaching inquiry across all social studies disciplines [history, civics, geography, economics], few studies examine the civic readiness of middle-graders using inquiry-based approaches, such as the IDM. Likewise, research examining how different schools are equipped with civic learning opportunities, practices, and access to resources for students is limited. This study employed a multiple-case design to investigate how inquiry-based instructional approaches, such as IDM, foster the civic readiness of middle graders in seven middle-grade social studies classrooms in a midwestern school. Multiple datasets were used, including 14 teacher interviews with seven middle-level social studies teachers, 162 class observation hours, and 246 documents/content analyses. This study argues that there are barriers to middle graders’ civic readiness, and teachers employ different strategies in diagnosing and addressing the barriers; however, inquiry teaching, using the IDM, is an effective instructional approach and plays a pivotal role in fostering civic readiness of middle graders. The findings highlight seven barriers for middle graders in their preparation for civic readiness. Participants shared five strategic ways to diagnose those barriers and five approaches to address them. The study further highlights practical implications for teachers and students, teacher preparation programs, policymakers and teacher educators, and future research.

description: The lightning activity in Saturn's atmosphere has been monitored by Cassini for more than six years. The continuous observations of the radio signatures called SEDs (Saturn Electrostatic Discharges) combine favorably with imaging observations of related cloud features as well as direct observations of flash-illuminated cloud tops. The Cassini RPWS (Radio and Plasma Wave Science) instrument and ISS (Imaging Science Subsystem) in orbit around Saturn also received ground-based support: The intense SED radio waves were also detected by the giant UTR-2 radio telescope, and committed amateurs observed SED-related white spots with their backyard optical telescopes. Furthermore, the Cassini VIMS (Visual and Infrared Mapping Spectrometer) and CIRS (Composite Infrared Spectrometer) instruments have provided some information on chemical constituents possibly created by the lightning discharges and transported upward to Saturn's upper atmosphere by vertical convection. In this paper we summarize the main results on Saturn lightning provided by this multi-instrumental approach and compare Saturn lightning to lightning on Jupiter and Earth.

description: The stellar cluster environment is expected to play a central role in the evolution of circumstellar disks. We use thermochemical modeling to constrain the dust and gas masses, disk sizes, UV and X-ray radiation fields, viewing geometries, and central stellar masses of 20 Class II disks in the Orion Nebula Cluster (ONC). We fit a large grid of disk models to $350$ GHz continuum, CO $J=3-2$, and HCO$^+$ $J=4-3$ ALMA observations of each target, and we introduce a procedure for modeling interferometric observations of gas disks detected in absorption against a bright molecular cloud background. We find that the ONC disks are massive and compact, with typical radii $<100$ AU, gas masses $\geq10^{-3}$ $M_{\odot}$, and gas-to-dust ratios $\geq100$. The ISM-like gas-to-dust ratios derived from our modeling suggest that compact, externally-irradiated disks in the ONC are less prone to gas-phase CO depletion than the massive and extended gas disks that are commonly found in nearby low-mass star-forming regions. The presence of massive gas disks indicates that external photoevaporation may have only recently begun operating in the ONC, though it remains unclear whether other cluster members are older and more evaporated than the ones in our sample. Finally, we compare our dynamically-derived stellar masses with the stellar masses predicted from evolutionary models and find excellent agreement. Our study has significantly increased the number of dynamical mass measurements in the mass range $\leq 0.5$ $M_{\odot}$, demonstrating that the ONC is an ideal region for obtaining large samples of dynamical mass measurements towards low-mass M-dwarfs.

description: The distributions of deuterated molecules in protoplanetary disks are expected to depend on the molecular formation pathways. We use observations of spatially resolved DCN emission from the disk around TW Hya, acquired during ALMA Science verification with a ~3" synthesized beam, together with comparable DCO+ observations from the Submillimeter Array, to investigate differences in the radial distributions of these species and hence differences in their formation chemistry. In contrast to DCO+, which shows an increasing column density with radius, DCN is better fit by a model that is centrally peaked. We infer that DCN forms at a smaller radii and thus at higher temperatures than DCO+. This is consistent with chemical network model predictions of DCO+ formation from H2D+ at T<30 K and DCN formation from additional pathways involving CH2D+ at higher temperatures. We estimate a DCN/HCN abundance ratio of ~0.017, similar to the DCO+/HCO+ abundance ratio. Deuterium fractionation appears to be efficient at a range of temperatures in this protoplanetary disk. These results suggest caution in interpreting the range of deuterium fractions observed in Solar System bodies, as multiple formation pathways should be taken into account.

We explain this phenomenon and describe subsequent steps.

description: We study the conformation and dynamics of a single polymer chain that is pulled by a constant force applied at its one end with the other end free. Such a situation is relevant to the growing technology of manipulating individual macromolecules, which offers a paradigm research for probing far-from-equilibrium responses of long flexible biological polymers. We first analyze the Rouse model for the Gaussian chains for which the exact analytical results can be obtained. More realistic features such as the finite extensibility, the excluded volume and the hydrodynamic interactions are taken into account with the help of the scaling argument, which leads to various nontrivial predictions such as the stretching-force-dependent friction constants. We elucidate (i) generalized dynamical equations of state describing extension/friction laws in steady-state and (ii) the tension propagation laws in the transient process. We point out that the time evolutions of the dynamic friction in the transient process crucially depend on the experimental protocol, i.e., either constant force or velocity ensemble, which might be detectable in experiments using giant DNAs and chromosomes.

description: Note: Originally published by the University of Windsor, 1997. Sensation seeking and impulsivity are two constructs of personality that are generally believed to be associated with risky behaviour including gambling. However, little empirical research has investigated this relationship. Similarly, there has been sparse research looking at whether or not gambling is actually related to other risky behaviors. The purpose of this study is to investigate these relationships. One hundred and forty-four male undergraduate university students completed several inventories measuring sensation seeking, impulsivity, gambling, and risky behaviors. Statistical analyses including correlations and regressions were run to determine the relationship between these constructs. A very high percentage of probable pathological gamblers was found in this study. Also, a significant difference was found between the relationships of sensation seeking, impulsivity, and risky behaviors with gambling when pathological and non-pathological gamblers were examined. Results should guide future research in these areas.

description: This paper interrogates the development scenarios proliferating in the Serbian public sphere since the ‘Democratic change’ of October 2000. While the state’s mythologizing of ‘progress’ and the promise of development are reaching a peak under the current regime, the rhetoric of ‘new’ post- socialist and post-democratic modernity is losing its momentum. The disillusioned and the disenfranchised of the Serbian society – the rural and the disadvantaged populations – have begun to react to the continuing attempts at plunder of the land and its resources outside of the existing political venues and purposefully away from the established political elites. The paper explores potentials in the current emergence of values and understandings of life essentials of the people of the land, embodied in the popular movement and uprisings against the ‘theft of rivers’, occurring despite the constructed but all-consuming discourse of non-alternatives to the mainstream idea of ‘progress’.

description: Excitons in lead bromide perovskites exhibit high binding energy and high oscillator strength, allowing for a strong light-matter coupling regime in the perovskite-based cavities localizing photons at the nanoscale. This opens up the way for the realization of exciton-polariton Bose-Einstein condensation and polariton lasing at room temperature -- the inversion-free low-threshold stimulated emission. However, polariton lasing in perovskite planar photon cavities without Bragg mirrors has not yet been observed and proved experimentally. In this work, we employ perovskite metasurface, fabricated with nanoimprint lithography, supporting so-called exceptional points to demonstrate the room-temperature polariton lasing. The exceptional points in exciton-polariton dispersion of the metasurface appear upon optically pumping in the nonlinear regime in the spectral vicinity of a symmetry-protected bound state in the continuum providing high mode confinement with the enhanced local density of states beneficial for polariton condensation. The observed lasing emission possesses high directivity with a divergence angle of around 1$^\circ$ over one axis. The employed nanoimprinting approach for solution-processable large-scale polariton lasers is compatible with various planar photonic platforms suitable for on-chip integration.

description: The mass and spin of black holes (BHs) in binary systems may change due to the infall of gravitational-wave (GW) energy down the horizons. For spinning BHs, this effect enters at 2.5 post-Newtonian (PN) order relative to the leading-order energy flux at infinity. There is currently a discrepancy in the literature in the expressions of these horizon fluxes in the test-body limit at 4PN order (relative 1.5PN order). Here, we model the horizon absorption as tidal heating in an effective worldline theory of a spinning particle equipped with tidally-induced quadrupole and octupole moments. We match the tidal response to analytic solutions of the Teukolsky equation in a scattering scenario, and obtain general formulae for the evolution of mass and spin. We then specialize to the case of aligned-spin--quasi-circular binaries, obtaining the corresponding contributions to the GW phasing through 4PN order. Importantly, we find that the number of GW cycles due to horizon fluxes with masses observed by LIGO-Virgo-KAGRA detectors is about 2-3 orders of magnitude smaller than the other contributions to the phasing at the same PN order. Furthermore, in the test-body limit, we find full agreement with results obtained earlier from BH perturbation theory, with a small mass in an equatorial circular orbit treated as a source perturbing the Kerr metric. Thus, we weigh in on one side of the previous discrepancy.

Analytic Regularization in Soft-Collinear Effective Theory

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: In high-energy processes which are sensitive to small transverse momenta, individual contributions from collinear and soft momentum regions are not separately well-defined in dimensional regularization. A simple possibility to solve this problem is to introduce additional analytic regulators. We point out that in massless theories the unregularized singularities only appear in real-emission diagrams and that the additional regulators can be introduced in such a way that gauge invariance and the factorized eikonal structure of soft and collinear emissions is maintained. This simplifies factorization proofs and implies, at least in the massless case, that the structure of Soft-Collinear Effective Theory remains completely unchanged by the presence of the additional regulators. Our formalism also provides a simple operator definition of transverse parton distribution functions.

Writing scripts and learning lines: an exploration of improvisation within primary PE provision and the emergence of watchfulness
Creators: name: Windsor, Stanley
Publisher: name: Loughborough University
Year: 2023

description: Research concerning the current state of provision for primary school Physical Education (PE) within England has accelerated in the last decade; exacerbated by the spotlight drawn to it from being included as an Olympic legacy following the 2012 Games. Existing literature has paid particular attention to questioning the role of professional coaches being deployed in education. Equally, research has suggested that there are stark differences between how different socioeconomic environments approach PE provision. The overarching aim of this thesis was to explore the current landscape of funding and provision for PE within primary education and consider the implications for practice. Using a method of Comparative Ethnography, this thesis explored two sites from opposing socioeconomic environments, one utilising coach led provision and one teacher led provision. Through a year of immersive fieldwork, split equally between the two sites, I played an active role within the two schools, allowing me to gain an intimate understanding of the sites. As a product of this fieldwork, I co-produced a thick description of the professionals’ realities. I exposed the barriers and lack of support from structural, mechanical, and emotional enablers that exist within both socioeconomic environments. Through a process of analysis and sense-making I employed a dramaturgical lens which was used to highlight the significance that improvisation plays in guarding professionals from their vulnerabilities around PE provision. As a consequence of uncontrolled improvisation, professional vulnerabilities emerge from both teachers and coaches. I established and explained how Watchful Vulnerabilities has been created as a result of the continued need for both teachers and coaches to perform PE provision that they are unprepared, untrained and unsupported in. Lastly, I have provided practical recommendations to how future provision might seek to reduce the barriers and, thus, eliminate Watchful Vulnerability from the provision.

description: Holomorphic gauge fields in N=1 supersymmetric heterotic compactifications can constrain the complex structure moduli of a Calabi-Yau manifold. In this paper, the tools necessary to use holomorphic bundles as a mechanism for moduli stabilization are systematically developed. We review the requisite deformation theory -- including the Atiyah class, which determines the deformations of the complex structure for which the gauge bundle becomes non-holomorphic and, hence, non-supersymmetric. In addition, two equivalent approaches to this mechanism of moduli stabilization are presented. The first is an efficient computational algorithm for determining the supersymmetric moduli space, while the second is an F-term potential in the four-dimensional theory associated with vector bundle holomorphy. These three methods are proven to be rigorously equivalent. We present explicit examples in which large numbers of complex structure moduli are stabilized. Finally, higher-order corrections to the moduli space are discussed.

description: Chemotactic active particles, such as bacteria and cells, exhibit an adaptive run-and-tumble motion, giving rise to complex emergent behaviors in response to external chemical fields. This motion is generated by the conversion of internal chemical energy into self-propulsion, allowing each agent to sustain a steady-state far from thermal equilibrium and perform works. The rate of entropy production serves as an indicates of how extensive these agents operate away from thermal equilibrium, providing a measure for estimating maximum obtainable power. Here we present the general framework for calculating the entropy production rate created by such population of agents from the first principle, using the minimal model of bacterial adaptive chemotaxis, as they execute the most basic collective action -- the mass transport.

Der Band liefert Beispiele, die von der Physik, insbesondere der Teilchenphysik, über die Astronomie, die Chemie (z. B. Chiralität) und die Biologie (z. B. Fortbewegung) bis in das Gebiet der Medizin (z. B. Krebsentstehung und Wundheilung) reichen. Außerdem werden Symmetriebrüche in der Moral, die Rolle von Symmetrie und Asymmetrie in der bildenden Kunst und die Symmetrie als strukturelles Prinzip des Denkens in der Moderne untersucht.

description: Increased groundwater withdrawals associated with agricultural irrigation in the Jackson Purchase have prompted questions related to groundwater availability and sustainability. Key factors in addressing these questions are understanding the extent and variation in thickness of the local hydrostratigraphic system, which is the upper part of the Mississippi Embayment aquifer system. Correlations of 70 gamma-ray well logs, and 49 resistivity logs were made across parts of the Jackson Purchase in Fulton and Hickman Counties in order to delineate the upper Claiborne aquifer and middle Claiborne confining unit. Commercial software (i.e. Petra 3.8.3) was used to generate cross sections, structure and isopach maps of the upper Claiborne aquifer, middle Claiborne confining unit, and middle Claiborne aquifer. The structure and isopach maps show the upper Claiborne aquifer and middle Claiborne confining unit thickening and dipping southwest into the embayment. In an effort to test different methods for mapping these hydrostatic units in the shallow sub-surface, surface electrical resistivity and a seismic walkaway sounding were acquired and compared with downhole geophysical logs at two well-constrained sites to test their limits for resolving these hydrostratigraphic units. Both electric resistivity and seismic geophysical methods were best able to image the Claiborne aquifer system when used together.
Net physical transports, residence times, and new production for Rivers Inlet, British Columbia

description: A hydrographic dataset from the 2008-2009 Rivers Inlet Ecosystem Study (RIES) field program was used (a) to provide a more complete oceanographic description of Rivers Inlet, British Columbia and (b) to develop the first quantitative estimates of estuarine circulation and new production for this system. Water column observations show a highly stratified two-layer estuarine structure, particularly in the spring and summer months when river discharge and atmospheric heat inputs were high. The net air-sea heat flux had a seasonal range of approximately 220 Wm⁻² and peaked almost a month earlier in 2008 than in 2009. The main source of river input comes from the Wannock River. As temperatures begin to rise in the spring, the river discharge can suddenly increase by an order of magnitude (from about 100 m³ s⁻¹ to almost 1000 m³ s⁻¹) in less than two weeks. Residence times (ie. first-order estimates of estuarine circulation) were estimated for every cruise using salinity and temperature budgets in a two-layer box model parameterization of the flow structure. The results show that upper box residence times vary seasonally with river discharge; dropping from about 14 days in the winter to as low as 4 days in the spring at the freshet onset. An earlier flushing event in 2009 caused residence times to drop earlier and could have caused higher advection losses for phytoplankton in the early spring. Overall, residence times averaged to about 7 days for the upper layer and about 165 days for the lower layer during periods of high river discharge, and about twice that during periods of low river discharge. Deep water in the lower layer below the sill was renewed almost once a year in summer and was affected only by vertical diffusion during the rest of the year. Finally, a spring/summer new production estimate of 0.6-1.7 gCm⁻²d⁻¹ (which implies about 110-300 gCm⁻²y⁻¹ assuming no production during the other months) was obtained by combining transport estimates with observations of nutrients to infer a surface nitrate sink. This range compares well with independent estimates made in nearby regions.

description: Important diagnostics of the star/circumstellar interaction region of Herbig Ae/Be stars are accessible by examining the temporal behavior of the near-IR spectral lines He I λ10830 and  Paschen gamma. We reduced and analyzed 30 spectra of the strongly magnetic Herbig Ae star HD101412, acquired with the CRIRES and X-shooter spectrographs installed at the VLT (ESO, Chile). We found that the temporal behavior of these diagnostic lines in the near-infrared spectra can be explained by rotational modulation of line profiles generated by accreting gas with a period P = 20.53d. This period is about half of the magnetic rotation period P = 42.76d previously determined from measurements of the mean longitudinal magnetic field. Our finding indicates that the accreted matter falls onto the star in

regions close to the magnetic poles intersecting the line-of-sight twice during the rotation cycle. The results of our study clearly demonstrate the power of such an analysis to diagnose the physical properties of accretion flows onto pre-main sequence stars.

description: The General Antiparticle Spectrometer (GAPS) is a balloon-borne experiment that aims to measure low-energy cosmic-ray antiparticles. GAPS has developed a new antiparticle identification technique based on exotic atom formation caused by incident particles, which is achieved by ten layers of Si(Li) detector tracker in GAPS. The conventional analysis uses the physical quantities of the reconstructed incident and secondary particles. In parallel with this, we have developed a complementary approach based on deep neural networks. This paper presents a new convolutional neural network (CNN) technique. A three-dimensional CNN takes energy depositions as three-dimensional inputs and learns to identify their positional/energy correlations. The combination of the physical quantities and the CNN technique is also investigated. The findings show that the new technique outperforms existing machine learning-based methods in particle identification.

description: The problem of anomalous scaling in magnetohydrodynamics turbulence is considered within the framework of the kinematic approximation, in the presence of a large-scale background magnetic field. Field theoretic renormalization group methods are applied to the Kazantsev-Kraichnan model of a passive vector advected by the Gaussian velocity field with zero mean and correlation function $\propto δ(t-t')/k^{d+ε}$. Inertial-range anomalous scaling for the tensor pair correlators is established as a consequence of the existence in the corresponding operator product expansions of certain "dangerous" composite operators, whose negative critical dimensions determine the anomalous exponents. The main technical result is the calculation of the anomalous exponents in the order $ε^2$ of the $ε$ expansion (two-loop approximation).

description: Although the route towards many phases in quantum materials is an open question that admits several answers, for the formation of Density Waves a good candidate is believed to be Fermi surfaces nesting in various materials e.g iron pnictides, organics and transition metals. The motivation of this work came from the physics of Sr3Ru2O7, but the model we treat is very general. First we review recent works aiming to understand whether nesting itself is capable to generate SDW order and we show that indeed Density Waves can be formed between two nearly nested Fermi Surfaces. We present a very general scenario in order to study the fate of the SDW phase primarily formed between the nearly nested patches in the case when a higher order Van Hove singularity emerges as the chemical potential is tuned. We study the competition of the phases (SDW, CDW, superconductivity) in weak-coupling case applying the parquet RG approach. The results of this work are applicable to numerous 2D strongly correlated systems which undergo topological quantum phase transitions such as Sr3Ru2O7, transition metal dichalcogenides, bilayer and twisted bilayer graphene.
