description: The common assumption that deep groundwater storage variations and interbasin lateral groundwater flow are a negligibly small component of the total water budget was tested using modelled, remotely sensed, and in-situ data. A total water budget using Gravity Recovery And Climate Experiment (GRACE) data was compared to a surface water budget derived from remotely sensed precipitation, evapotranspiration, and gauged streamflow to examine whether interbasin groundwater flow can be isolated using remote sensing tools. Additionally, GRACE observed changes in total water storage was disaggregated using data from the Global Land Data Assimilation System (GLDAS) to isolate groundwater storage anomalies and were compared to estimates of pumping in the Guarani Aquifer. Sen’s slope estimator and Mann-Kendall significance tests were used to evaluate groundwater storage trends. Head variations are calculated based on assumed partitioning of groundwater storage anomalies and used to demonstrate that nearly all monthly variations in groundwater storage are associated with storage changes in unconfined aquifers.Results of this study suggest that each of the six watersheds evaluated was experiencing net lateral groundwater flow out of the basin and that nearly all groundwater storage variations on the monthly timescale are associated with storage changes in shallow unconfined aquifers. It is further suggested that lateral groundwater flow in the Guarani Aquifer underlying the state of Sao Paulo is sufficiently large to partially offset pumping withdrawals.

description: The inelastic dark matter scenario was proposed to reconcile the DAMA annual modulation with null results from other experiments. In this scenario, WIMPs scatter into an excited state, split from the ground state by an energy delta comparable to the available kinetic energy of a Galactic WIMP. We note that for large splittings delta, the dominant scattering at DAMA can occur off of thallium nuclei, with A~205, which are present as a dopant at the 10^-3 level in NaI(Tl) crystals. For a WIMP mass m~100GeV and delta~200keV, we find a region in delta-m-parameter space which is consistent with all experiments. These parameters in particular can be probed in experiments with thallium in their targets, such as KIMS, but are inaccessible to lighter target experiments. Depending on the tail of the WIMP velocity distribution, a highly modulated signal may or may not appear at CRESST-II.

description: In this work we attempt to elucidate the nature of conductivity in polymers by taking the acid-base doped polyaniline (PAni) polymer. We evaluate the PAni conductance by using realistic ab initio parameters and including decoherent processes within the minimal parametrization model of D'Amato-Pastawski. In contrast to general wisdom, which associates the conducting state with coherent propagation in a periodic polaronic lattice, we show that decoherence can account for high conductance in the strongly disordered bipolaronic lattice. Hence, according to our results, there is no need of considering a mix model of "conducting" polaronic lattice islands separated by "insulating" bipolaronic lattice strands as is usually assumed for PAni. We find that without dephasing events, even very short strands of bipolaronic lattices are not able to sustain electronic transport. We also include a discussion of specific mechanisms that should be involved in decoherence rates of PAni and relate them with Marcus-Hush theory of electron transfer.

description: Chiral symmetry is one of the most fundamental symmetries in QCD. It is closely connected to hadron properties in the nuclear medium via the reduction of the quark condensate , manifesting the partial restoration of chiral symmetry. To better understand this important issue, a number of Jefferson Lab experiments over the past decade have focused on understanding properties of mesons and nucleons in the nuclear medium, often benefiting from the high polarization and luminosity of the CEBAF accelerator. In particular, a novel, accurate, polarization transfer measurement technique revealed for the first time a strong indication that the bound proton electromagnetic form factors in 4He may be modified compared to those in the vacuum. Second, the photoproduction of vector mesons on various nuclei has been measured via their decay to e+e- to study possible in-medium effects on the properties of the rho meson. In this experiment, no significant mass shift and some broadening consistent with expected collisional broadening for the rho meson has been observed, providing tight constraints on model calculations. Finally, processes involving in-medium parton propagation have been studied. The medium modifications of the quark fragmentation functions have been extracted with much higher statistical accuracy than previously possible.

description: Generalizations of the three main equations of quantum physics, namely, the Schrödinger, Klein-Gordon, and Dirac equations, are proposed. Nonlinear terms, characterized by exponents depending on an index $q$, are considered in such a way that the standard linear equations are recovered in the limit $q \rightarrow 1$. Interestingly, these equations present a common, soliton-like, travelling solution, which is written in terms of the $q$-exponential function that naturally emerges within nonextensive statistical mechanics. In all cases, the well-known Einstein energy-momentum relation is preserved for arbitrary values of $q$.

description: Recently, we reported induced anoxia as a limiting factor for photodynamic tumor therapy (PDT). This effect occurs in vivo if the amount of generated singlet oxygen that undergoes chemical reactions with cellular components exceeds the local oxygen supply. The amount of generated singlet oxygen depends mainly on photosensitizer (PS) accumulation, efficiency, and illumination intensity. With illumination intensities above a certain threshold, singlet oxygen is limited to the blood vessel and the nearest vicinity; lower intensities allow singlet oxygen generation also in tissue which is a few cell layers away from the vessels. While all experiments so far were limited to light intensities above this threshold, we report experimental results for intensities at both sides of the threshold for the first time, giving proof for the described model. Using time-resolved optical detection in NIR, we demonstrate characteristic, illumination intensity-dependent changes in signal kinetics of singlet oxygen and photosensitizer phosphorescence in vivo. The described analysis allows for better optimization and coordination of PDT drugs and treatment, as well as new diagnostic methods based on gated PS phosphorescence, for which we report a first in vivo feasibility test.

description: A generic prediction in the paradigm of weakly interacting dark matter is the production of relativistic particles from dark matter pair-annihilation in regions of high dark matter density. Ultra-relativistic electrons and positrons produced in the center of the Galaxy by dark matter annihilation should produce a diffuse synchrotron emission. While the spectral shape of the synchrotron dark matter haze depends on the particle model (and secondarily on the galactic magnetic fields), the morphology of the haze depends primarily on (1) the dark matter density distribution, (2) the galactic magnetic field morphology, and (3) the diffusion model for high-energy cosmic-ray leptons. Interestingly, an unidentified excess of microwave radiation with characteristics similar to those predicted by dark matter models has been claimed to exist near the galactic center region in the data reported by the WMAP satellite, and dubbed the "WMAP haze". In this study, we carry out a self-consistent treatment of the variables enumerated above, enforcing constraints from the available data on cosmic rays, radio surveys and diffuse gamma rays. We outline and make predictions for the general morphology and spectral features of a "dark matter haze" and we compare them to the WMAP haze data. We also characterize and study the spectrum and spatial distribution of the inverse Compton emission resulting from the same population of energetic electrons and positrons. We point out that the spectrum and morphology of the radio emission at different frequencies is a powerful diagnostics to test whether a galactic synchrotron haze indeed originates from dark matter annihilation.

Identifying predictive gene expression signatures of sepsis severity
Creators: name: Baghela, Arjun
Publisher: name: University of British Columbia

description: Sepsis is a common and very heterogenous syndrome defined as the life-threatening organ dysfunction caused by an aberrant host response to infection. In the earliest stages, sepsis diagnoses are often missed due to non-specific symptomatology resulting in a rapid progression to severe sepsis. Gene expression signatures that measure host immune responses have been shown to provide more sensitive prognostic tools than existing clinical criteria, permitting early prediction of high-risk patients. We recruited, from six global cohorts, 266 suspected sepsis patients in the emergency room and 82 suspected pulmonary sepsis patients in the intensive care unit with varying disease severity, and 44 healthy controls. Most recently, I analyzed 135 patients with Covid-19 disease that showed immune responses overlapping with sepsis. From this, I identified candidate gene expression signatures reflecting endotypes and severity markers, using the transcriptomics method, RNA-Seq, and statistical and computational methods. I determined that early sepsis patients could be stratified into five endotypes defined by distinct pathobiological mechanisms, including unique gene expression differences and accurate, predictive gene expression pairs. Two of the five endotypes were associated with a higher tendency towards severe sepsis and mortality, two demonstrated much lower severity, and one was relatively benign. Diverse molecular responses were also observed independently of endotypes; thus, concomitant cross-cutting severity signatures that directly predicted sepsis-induced organ dysfunction and mortality were identified, in addition to dysregulated and co-expressed module genes. The endotype signatures were often consistent with cellular shifts in neutrophil numbers and function, whereas dysregulated molecular responses like cellular reprogramming and hyperinflammation reflected prognoses. These signatures were assessed in other conditions (e.g., pancreatitis, appendicitis, myocardial infarction), which indicated the signatures captured mechanisms specific to early sepsis/sepsis. A compendium of dysregulated genes and signatures in sepsis was curated from the literature, confirming that these signatures involved wellcharacterized genes. This study demonstrated that signatures relevant to the development of life-threatening sepsis can be observed as early as first entry into the ER. These signatures will enable the development of diagnostics and targeted therapeutics, and importantly, when used early in the sepsis disease course, could prevent rapid patient deterioration, mortality, and poor long-term outcomes.
Low-energy kink in the nodal dispersion of copper-oxide superconductors: Insights from Dynamical Mean Field Theory

description: Motivated by the observation in copper-oxide high-temperature superconductors, we investigate the appearance of kinks in the electronic dispersion due to coupling to phonons for a system with strong electronic repulsion. We study a Hubbard model supplemented by an electron-phonon coupling of Holstein type within Dynamical Mean Field Theory (DMFT) utilizing Numerical Renormalization Group as impurity solver. Paramagnetic DMFT solutions in the presence of large repulsion show a kink only for large values of the electron-phonon coupling $λ$ or large doping and, contrary to the conventional electron-phonon theory, the position of such a kink can be shifted to energies larger than the renormalized phonon frequency $ω_0^r$. When including antiferromagnetic correlations we find a stronger effect of the electron-phonon interaction on the electronic dispersion due to a cooperative effect and a visible kink at $ω_0^r$, even for smaller $λ$. Our results provide a scenario of a kink position increasing with doping, which could be related to recent photoemission experiments on Bi-based cuprates.

The perspectives of early childhood education and care practitioners in British Columbia on their outdoor play pedagogy

description: Compared with previous generations, young children in Canada have fewer opportunities to play outdoors and to experience the benefits of outdoor play such as improved physical and mental health and increased connection to the natural world. Early childhood education and care (ECEC) practitioners can increase young children’s access to outdoor play; however, they encounter challenges providing such opportunities. The purpose of this research project was to explore how ECEC practitioners who used an online outdoor play risk reframing tool (the ECO tool) describe outdoor play, their outdoor play pedagogy and the influences on their outdoor play pedagogy including the ECO tool and the COVID-19 pandemic. Eight ECEC practitioners in BC who used the ECO tool in a separate randomized control trial study of the tool were recruited for the present study. Using Symbolic Interactionism as the theoretical and methodological framework, qualitative data were collected from the participants through semi-structured online participant interviews. The ECEC practitioners described outdoor play as a valuable aspect of their programs, being child-driven, involving various forms of play, spending time in nature, and fun for children. The practitioners characterized their outdoor play pedagogy as being child-directed, and correspondingly that they minimized intervening in children’s outdoor play. Most practitioners portrayed their outdoor play pedagogy as juxtaposed to their indoor play pedagogy, where they adopted a more hands-off and less structured approach outdoors relative to indoors. Their outdoor play pedagogy also involved prioritizing time outdoors with children and providing a variety of affordances outdoors. The practitioners spoke of relationships with children, families, licensing, and colleagues as both constraints and supports on their outdoor play pedagogy. Most of the participants found that the ECO tool supported their outdoor play pedagogy; however, it had a neutral impact for a few participants. Finally, the COVID-19 created an impetus for these practitioners to enhance children’s opportunities for outdoor play, but they also encountered challenges related to the pandemic. Implications of the practitioners’ outdoor play pedagogy are discussed.

Year: 2020

description: The pre-trilobitic lower Cambrian of the Withycombe Formation is a 194 m thick siliciclastic succession dominated by interbedded offshore red to purple and green pyritic mudstone with minor sandstone. The mudstone contains a hyolith-dominated small shelly fauna including: orthothecid hyoliths, hyolithid hyoliths, the rostroconch Watsonella crosbyi, early brachiopods, the foraminiferan Platysolenites antiquissimus, the coiled gastropod-like Aldanella attleborensis, halkieriids, gastropods and a low diversity ichnofauna including evidence of predation by a vagile infaunal predator.
 The assemblage contains a number of important index fossils (Watsonella, Platysolenites, Aldanella and the trace fossil Teichichnus) that enable correlation of strata around the base of Cambrian Stage 2 from Avalonia to Baltica, as well as the assessment of the stratigraphy within the context of the lower Cambrian stratigraphic standards of southeastern Newfoundland.
 The pyritized nature of the assemblage has enabled the study of some of the biota using micro-CT, augmented with petrographic studies, revealing pyritized microbial filaments of probable giant sulfur bacteria. We aim to produce the first complete description of the core and the abundant small pyritized fossils preserved in it, and develop a taphonomic model for the pyritization of the “small” shelly fossils.

description: As a microcosm of the greater US, Midwestern culture is based upon traveling, bucolic ideals, and cyclic poverty. Tattooed Midwestern women occupy a unique position within the culture; they embody a story-- personal, political, collective, and cultural. The ink that rests in the dermis of tattooed Midwestern women holds multiple layers of significance, used as a way of expression, connecting to other people, and healing emotional wounds. Cultural expectations encourage women with tattoos to share their narrative as a way of validating and aligning their bodies with traditionally conservative understandings of the female form. Midwestern women instilled with a compulsory cordiality and spurred by general accessibility, assign meaning to their tattoos and the stories that accompany them. Tattoo chronicles of Midwestern women answer for the marked female body.
Theory of Feedback in Clusters and Molecular Cloud Turbulence

description: I review recent numerical and analytical work on the feedback from both low- and high-mass cluster stars into their gasoeus environment. The main conclusions are that i) outflow driving appears capable of maintaing the turbulence in parsec-sized clumps and retarding their collapse from the free-fall rate, although there exist regions within molecular clouds, and even some examples of whole clouds, which are not actively forming stars, yet are just as turbulent, so that a more universal turbulence-driving mechanism is needed; ii) outflow-driven turbulence exhibits specific spectral features that can be tested observationally; iii) feedback plays an important role in reducing the star formation rate; iv) nevertheless, numerical simulations suggest that feedback cannot completely prevent a net contracting motion of clouds and clumps. Therefore, an appealing source for driving the turbulence everywhere in GMCs is the accretion from the environment, at all scales. In this case, feedback's most important role may be to prevent a fraction of the gas nearest to newly formed stars from actually reaching them, thus reducing the star formation efficiency.

title: 'O Brother, Where Art Thou?' Investigating the Role of Religious Specialists in the Early Minoan Tholos Cemeteries of South-Central Crete
Creators: name: Gaynor, J
Publisher: name: University of Liverpool Repository
Year: 2024

description: The primary objective of this thesis is to investigate evidence for religious specialists in the Early Minoan period using a theoretical and methodological approach grounded in landscape archaeology, to reinvestigate the tholos cemeteries of south-central Crete. The dominance of Arthur Evans’s ‘Minoan’ project has ensured that religious specialists are rarely if ever considered outside of the narrow confines of the ‘priests’ and ‘priestesses’ of the later ‘palatial’ eras, but this study argues that they should instead be considered as craft specialists, and the tholos tomb cemeteries should be treated as centres of craft production, or as craftspheres as they will be referred to here. In the early-EM I period, a newly emerging belief system in south-central Crete is represented in the archaeological record by the construction of purpose-built spaces – the island’s first form of monumental architecture – where these communities buried their dead and gathered to practise a religion based around mortuary practices. Over time, the evolution of this belief system is reflected in architectural developments at these cemeteries, which incorporated outdoor spaces to include larger crowds. Specialists were needed to translate the religious ideologies of these communities into built spaces, and to mediate the activities that these spaces facilitated. This thesis analyses how religious architectures in south-central Crete – their conceptualisation, construction, and development over time – embodies the ambitions and objectives of those who built and used them. Landscape archaeology is used to reconsider the material remains of built spaces. The creation of space is analysed through the use of architectural energetics to better understand the resources expended on tholos cemeteries as centres of craft production. In communal cemeteries like these, the labour costs afforded to their construction confirms that coordination was needed in the construction of built spaces. A multi-sensory approach is also used to navigate how space was used and experienced. This considers how architecture was used to guide (or manipulate) the sensory experiences of religious celebrants at tholos cemeteries. By understanding how space was built and used we can begin to understand the influence of religious specialists in this early period.

description: The phenomenon of super-radiance (Dicke effect, coherent spontaneous radiation by a gas of atoms coupled through the common radiation field) is well known in quantum optics. The review discusses similar physics that emerges in open and marginally stable quantum many-body systems. In the presence of open decay channels, the intrinsic states are coupled through the continuum. At sufficiently strong continuum coupling, the spectrum of resonances undergoes the restructuring with segregation of very broad super-radiant states and trapping of remaining long-lived compound states. The appropriate formalism describing this phenomenon is based on the Feshbach projection method and effective non-Hermitian Hamiltonian. A broader generalization is related to the idea of doorway states connecting quantum states of different structure. The method is explained in detail and the examples of applications are given to nuclear, atomic and particle physics. The interrelation of the collective dynamics through continuum and possible intrinsic many-body chaos is studied, including universal mesoscopic conductance fluctuations. The theory serves as a natural framework for general description of a quantum signal transmission through an open mesoscopic system.

Energy Efficient Hardware for Neural Network Applications

description: With the explosion of AI in recent years, there has been an exponential rise in the demand for computing resources. Although Moore’s law has so far kept up with conventional computational demands in the past, it has become evident that the efficiency and area gains with transistor scaling are no longer exponential, but rather incremental. The standard Von Neumann architecture imposes a limit on efficiency and latency as data is shuttled repeatedly between the compute and memory units. On the other hand, AI workloads rely heavily on matrix-vector-multiplication which get exponentially expensive with vector widths. In-memory and near-memory computing have come up as promising alternatives that addresses both these issues elegantly while reducing energy requirements. A variety of NN models rely on fast and repetitive evaluation of exponential transcendental functions. In many cases, this is done by range reduction technique and math tables. For optimal energy efficiency and throughput, it is best if these tables reside as close as possible to the circuit where it is consumed. We propose a mixed-signal macro with dual functionality: ability to do matrix vector multiplication as well evaluate exp(x) for 32-bit IEEE 754 floating point number. The said macro consists of 64x64 array of special 8T cells that stores the math tables without hindering normal SRAM functionality. The charge based MVM engine uses two ADCs with reconfigurable precision, allowing faster throughput for sparse inputs. As the outputs of these operations are separate, it allows for high flexibility to use the macro in any neural-network hardware that needs either or both the functions.
 Spiking Neural Networks (SNN) can perform sequential learning tasks efficiently by using the inherent recurrence of membrane potential (Vmem) accumulation over several timesteps. However, the data movement of Vmem creates additional memory accesses, which becomes a bottleneck operation. Additionally, SNN input spikes are highly sparse in nature, which can be exploited for efficient hardware implementation. We propose an SNN accelerator based on in-memory processing that addresses these. The said accelerator consists of 9 compute macros and 3 neuron macros, which can be programmed to work either serially (9 compute, 1 neuron) or in 3 parallel sets (3 compute, 1 neuron) to support different layer sizes. Peripheral logic computes the membrane potential and stores it in the same compute macro, thus avoiding unnecessary data movement. The neuron macro keeps track of final membrane potential and generates output spikes. This accelerator was designed to run at 200Mhz at 1.2v in TSMC 65nm node.

description: We study the lattice spacing dependence, or scaling, of physical quantities using the highly improved staggered quark (HISQ) action introduced by the HPQCD/UKQCD collaboration, comparing our results to similar simulations with the asqtad fermion action. Results are based on calculations with lattice spacings approximately 0.15, 0.12 and 0.09 fm, using four flavors of dynamical HISQ quarks. The strange and charm quark masses are near their physical values, and the light-quark mass is set to 0.2 times the strange-quark mass. We look at the lattice spacing dependence of hadron masses, pseudoscalar meson decay constants, and the topological susceptibility. In addition to the commonly used determination of the lattice spacing through the static quark potential, we examine a determination proposed by the HPQCD collaboration that uses the decay constant of a fictitious "unmixed s bar s" pseudoscalar meson. We find that the lattice artifacts in the HISQ simulations are much smaller than those in the asqtad simulations at the same lattice spacings and quark masses.

description: Motivated by the recent experimental data [Phys. Rev. B 79, 100502 (2009)] indicating the existence of a pure stripe charge order over unprecedently wide temperature range in La_{1.8-x}Eu_{0.2}Sr_xCuO_4, we investigate the temperature-induced melting of the metallic stripe phase. In spite of taking into account local dynamic correlations within a real-space dynamical mean-field theory of the Hubbard model, we observe a mean-field like melting of the stripe order irrespective of the choice of the next-nearest neighbor hopping. The temperature dependence of the single-particle spectral function shows the stripe induced formation of a flat band around the antinodal points accompanied by the opening a gap in the nodal direction.

description: In order to characterize how dark matter (DM) annihilation inside stars changes the aspect of a stellar cluster we computed the evolution until the ignition of the He burning of stars from 0.7 to 3.5 M_sun within halos of DM with different characteristics. We found that, when a cluster is surrounded by a dense DM halo, the positions of the cluster' stars in the H-R diagram have a brighter and hotter turn-off point than in the classical scenario without DM, therefore giving the cluster a younger appearance. The high DM densities required to produce these effects are expected only in very specific locations, such as near the center of our Galaxy. In particular, if DM is formed by the 8 GeV WIMPs recently invoked to reconcile the results from direct detection experiments, then this signature is predicted for halos of DM with a density rho_DM = 3 \cdot 10^5 GeV cm^3. A DM density gradient inside the stellar cluster would result in a broader main sequence, turn-off and red giant branch regions. Moreover, we found that for very high DM halo densities the bottom of the isochrones in the H-R diagram rises to higher luminosities, leading to a characteristic signature on the stellar cluster. We argue that this signature could be used to indirectly probe the presence of DM particles in the location of a cluster.

The effects of hands-on learning on stem student motivation: a meta-analysis
Creators: name: Oje, Olufunso
Publisher: name: Washington State University
Year: 2024

description: Traditionally, the predominant instruction mode in a typical classroom is a lecture where instructors explain the concepts verbally. There is a growing use of different active learning techniques in the classroom today. Some of these techniques include game-based learning, flipped classroom, collaborative learning, and hands-on learning. While many studies, over the past 20 years, have investigated the effects of hands-on learning on student performance, other studies have also examined the effects of hands-on learning on student motivation. However, to date, there is no comprehensive synthesis of the literature on the effects of hands-on learning on student motivation, especially in Science, Technology, Engineering, and Mathematics (STEM). Hence, the overarching goal of this meta-analysis was to examine empirical research regarding the effects of hands-on learning on student motivation. Following well-established standards for conducting rigorous meta-analyses, selection criteria were developed, and searches were systematically conducted on relevant databases using specific keyword combinations for both published and unpublished studies investigating the effect. Data from 21 independent studies involving 2,087 participants were extracted and analyzed. Overall weighted mean effect size shows a moderate statistically significant hands-on learning effect (d = 0.50, SE = 0.08, p < 0.01). Several variables moderated the overall effect size in various ways. For example, both learners with low prior knowledge and high prior knowledge benefitted from hands-on learning. However, learners with low prior knowledge befitted more from hands-on learning than high prior knowledge learners. Learners at all educational levels equally benefitted from hands-on learning of science and engineering topics. There was no significant difference across educational levels. This meta-analysis suggests that hands-on learning in the classroom may be associated with increased motivation and, therefore, beneficial for learning. Theoretical and

description: Recently, the CDF and DØ collaborations have claimed that the CP violating phase in $B_s^0-\bar{B}_s^0$ mixing is large, which is contrary to the expectations in the Standard Model. Such a large phase suggests New Physics contributions to $B_s^0-\bar{B}_s^0$ mixing. Motivated by this, we reevaluate the constraints on R-parity violating contributions, including baryon number violating couplings not considered before, to the mixing mass matrix element $M^s_{12}$ from the recent measurements of $B_s^0-\bar{B}_s^0$ mixing. We show that present data allow us to put quite strong constraints on both the magnitudes and the weak phases of the R-parity violating parameters. Some of these bounds are better than the exciting ones, and some bounds are obtained for the first time. Near future experiments at the Tevatron, the LHC and B-factories can shrink or reveal the relevant parameter spaces of R-parity violating couplings.
