description: Upcoming space-based surveys such as Euclid and WFIRST-AFTA plan to measure Baryonic Acoustic Oscillations (BAOs) in order to study dark energy. These surveys will use IR slitless grism spectroscopy to measure redshifts of a large number of galaxies over a significant redshift range. In this paper, we use the WFC3 Infrared Spectroscopic Parallel Survey (WISP) to estimate the expected number of Halpha (Ha) emitters observable by these future surveys. WISP is an ongoing HST slitless spectroscopic survey, covering the 0.8-1.65micron wavelength range and allowing the detection of Ha emitters up to z~1.5 and [OIII] emitters to z~2.3. We derive the Ha-[OIII] bivariate line luminosity function for WISP galaxies at z~1 using a maximum likelihood estimator that properly accounts for uncertainties in line luminosity measurement, and demonstrate how it can be used to derive the Ha luminosity function from exclusively fitting [OIII] data. Using the z~2 [OIII] line luminosity function, and assuming that the relation between Ha and [OIII] luminosity does not change significantly over the redshift range, we predict the Ha number counts at z~2 - the upper end of the redshift range of interest for the future surveys. For the redshift range 0.7

description: The amniote clade Parareptilia is notable in that members of the clade exhibited a wide array of morphologies, were successful in a variety of ecological niches and survived the end-Permian mass extinction. In order to better understand how mass extinction events can affect clades that survive them, we investigate both the species richness and morphological diversity (disparity) of parareptiles over the course of their history. Furthermore, we examine our observations in the context of other metazoan clades, in order to identify post-extinction survivorship patterns that are present in the clade. The results of our study indicate that there was an early increase in parareptilian disparity, which then fluctuated over the course of the Permian, before it eventually declined sharply towards the end of the Permian and into the Triassic, corresponding with the end-Permian mass extinction event. Interestingly, this is a different trend to what is observed regarding parareptile richness, that shows an almost continuous increase until its overall peak at the end of the Late Permian. Moreover, richness did not experience the same sharp drop at the end of the Permian, reaching a plateau until the Anisian, before dropping sharply and remaining low, with the clade going extinct at the end of the Triassic. This observed pattern is likely due to the fact that, despite the extinction of several morphologically distinct parareptile clades, the procolophonoids, one of the largest parareptilian clades, were diversifying across the Permian–Triassic boundary. With the clade's low levels of disparity and eventually declining species richness, this pattern most resembles a ‘dead clade walking’ pattern.
Who Ya Longs To? Indigenous Land-Based Learning

“The purpose of education is to help students recognize who they are, to see their gifts, talents, and strengths and recognize the responsibility that accompanies these gifts, so they can survive, thrive, and contribute as they navigate through both the broader world and Indigenous cultures”

(Goulet & Goulet, 2014, p. 5). As educators, we continue to try and incorporate ways to encourage all students to thrive. This research project focused on educators who have successfully implemented land-based learning programs to engage students and as a way to incorporate and validate an Indigenous World View. By interviewing three teachers who have implemented or have been involved in successful land-based learning experiences and using a thematic qualitative analysis approach, themes of success were identified. The key findings that emerged were that land-based learning is an excellent pedagogical practice that benefits many students, generally has a higher success rate in engaging students in the learning process, and is

an ideal vehicle for developing relationships with students. Finally, the paper concludes by exploring some of the barriers to implementing land-based education and potential future steps regarding assessing and reporting land-based learning experiences. The recommendation from this study is that when incorporating land-based learning into one practice, one should pay attention to the pitfalls and barriers, plan accordingly, budget for such learning activities, and, if possible, incorporate local Elders or Knowledge Keepers into the learning plan and process.
DECENTERING ABILITIES AND NOCTURNAL BLOOD PRESSURE DIPPING IN YOUNG ADULTS

description: Decentering can be defined as one’s ability to detach from emotional thoughts and adopt a non-judgmental view. Prior studies on 8-week mindfulness-based stress reduction (MBSR) courses have demonstrated that as the ability to decenter increases, anxiety levels decrease. Our recent work has demonstrated that a higher ability to decenter is associated with lower arterial stiffness, however, it is unknown how decentering affects blood pressure patterns. The purpose of this study was to observe if decentering has an effect on nocturnal blood pressure dipping. Twenty- eight adults (age 25±1 years; BMI 26±1 kg/m2) volunteered for this study. All participants had a BMI <30 kg/m2, and reported no history of diabetes, smoking, or taking cardiovascular medication. Participants completed an 11-item decentering questionnaire that quantified their ability to disconnect from their emotions, then were asked to wear an ambulatory blood pressure monitor (ABPM) and actigraphy watch for 24-hours. Brachial blood pressures were measured by the ABPM every 20 minutes while awake and every 30 minutes while asleep. Systolic arterial pressure (SAP) and diastolic arterial pressure (DAP) dipping percentages were calculated by Spacelabs software from the mean values of both daytime and nighttime arterial blood pressure recordings, after adjusting sleep and wake times based on actigraphy data. Questionnaire data was analyzed using Exploratory Factor Analysis (EFA) and a reliability analysis. This revealed a three-factor structure that explained 71.53% of the variance, consisting of meta-awareness, disidentification, and nonreactivity. Nine items remained in the final questionnaire, after deleting two items which cross-loaded. Multiple linear regression analyses indicate disidentifcation as a significant predictor of SAP dipping (𝛽𝛽 = 3.333, p = 0.032) and DAP dipping (𝛽𝛽 = 3.898, p = 0.049). Preliminary results suggest that greater disidentifcation, as a component of decentering, may be associated with lower cardiovascular risk (greater SAP and DAP dipping). These findings provide promising insight into the benefits of MBSR and decentering on ambulatory blood pressure patterns, with the potential benefits of lowering overall risk for cardiovascular disease (CVD).

description: We give a detailed comparison of the hierarchical quantum master equation (HQME) method to a continuous-time quantum Monte Carlo (CT-QMC) approach, assessing the usability of these numerically exact schemes as impurity solvers in practical nonequilibrium calculations. We review the main characteristics of the methods and discuss the scaling of the associated numerical effort. We substantiate our discussion with explicit numerical results for the nonequilibrium transport properties of a single-site Anderson impurity. The numerical effort of the HQME scheme scales linearly with the simulation time but increases (at worst exponentially) with decreasing temperature. In contrast, CT-QMC is less restricted by temperature at short times, but in general the cost of going to longer times is also exponential. After establishing the numerical exactness of the HQME scheme, we use it to elucidate the influence of different ways to induce transport through the impurity on the initial dynamics, discuss the phenomenon of coherent current oscillations, known as current ringing, and explain the non-monotonic temperature dependence of the steady-state magnetization as a result of competing broadening effects. We also elucidate the pronounced non-linear magnetization dynamics, which appears on intermediate time scales in the presence of an asymmetric coupling to the electrodes.

description: This study represents an attempt to establish a relationship between maturation of the cerebellum and the ontogeny of eyeblink conditioning in the rat. Experiments 1 and 2 examined the effects of disrupting cerebellar maturation by neonatal exposure to the antimitotic agent methylazoxymethanol (MAM) on the ontogeny of eyeblink conditioning in infant rats. Experiment 1 demonstrated that neonatal exposure to MAM on Postnatal Day 4 (PND4) and 7 severely disrupted cerebellar maturation. This effect appeared to be specific in that there was no overt dysmorphology in other brain regions. MAM treatment also severely disrupted associative eyeblink conditioning in rats given training on PND24 and 25. However, exposure to MAM had no effect on the unconditioned response, T-maze delayed alternation, or conditioned suppression of ongoing behavior. In Experiment 2, MAM was given on PND4 and 7 and pups were tested behaviorally on PND17-18, 20-21, or 31-32. Cerebellar hypoplasia was most dramatic shortly after exposure. The cerebellar cortex continued to mature after exposure to MAM, but development of morphological endpoints examined here were static from PND19 to 33. Eyeblink conditioning was impaired at all ages, indicating that there was no functional recovery following neonatal exposure to MAM over the age range tested. These experiments suggest that normal cerebellar maturation may be important for the ontogeny of eyeblink conditioning.

description: P-type channels, a recently described form of voltage-gated calcium channels, are found in many central and peripheral neurons. In the present study, a partial cDNA clone sharing extensive nucleotide identity with a putative P-type voltage-gated calcium channel alpha 1 subunit was isolated from a small-cell lung carcinoma (SCLC) cell line. Anti-peptide antibodies generated to a unique acidic stretch in the IVS5-S6 linker region of the putative SCLC P-type channel reacted specifically with a SCLC fusion protein produced in bacteria and with a cell surface molecule in SCLC cells. Calcium currents in SCLC cells, measured by whole-cell patch clamp, were inhibited by these antibodies and by the P-type channel-specific toxin omega-agatoxin IVA. The inhibitory effects of the antibody and the toxin were not additive, consistent with their proposed action on the same type of channel. These results provide evidence for the expression of P-type calcium channels by SCLC cells. The expression of neuron-related molecules by these cells is of particular interest because small-cell lung carcinoma is frequently associated with paraneoplastic disorders affecting the nervous system.
title: Modelling the relation between climate change and undernutrition at the global-level: the use of multiple perspectives to gain new insights
Creators: name: Lloyd, SJ
Publisher: name: London School of Hygiene & Tropical Medicine
Year: 2021

description: Global-level models have consistently found that climate change will increase the risk of hunger. The climate-undernutrition relation is complex, and choices must be made about what is brought into focus, with these choices drawing attention to particular causes and solutions. A critical overview of the literature showed, however, that all previous models had adopted one general conceptualisation: less or lower quality food means more hunger. This leaves much unexplored. The central idea of this thesis is that when faced with complex health problems, a fuller understanding may be gained by developing multiple models, each adopting a different perspective. The thesis aims to develop a series of global-level climate-undernutrition models, with the insights from one model guiding the development of the next. These models are presented as four research papers. Papers 1 and 2 adopt a ‘crop productivity’ perspective to quantify stunting. The results suggest that future socioeconomic conditions will play a larger in role in shaping stunting than climate change. Thus, Paper 3 places food production in the background and asks how climate change may impact on stunting via its impacts on two socioeconomic factors: incomes and food price. The results imply that slowly rising food prices lead to decent farm incomes, which may reduce the risk climate change poses to nutrition in rural areas. Producer-consumer farmers, however, were not directly represented. Given this, Paper 4 assesses the health-related implications for rural populations of producer-consumer households practising different styles of farming in the global food system under climate change. The results suggest that how farming is done – whether more entrepreneurial- or peasant-like – will impact on future nutrition and the conditions that support rural health. Collectively, the research papers demonstrate the utility of a multiple model-approach to complexity, and the benefits of drawing on a range of theories when building models.

description: We consider multi-particle systems with linear deterministic hamiltonian dynamics. Besides Liouville measure it has continuum of invariant tori and thus continuum of invariant measures. But if one specified particle is subjected to a simple linear deterministic transformation (velocity flip) in random time moments, we prove convergence to Liouville measure for any initial state. For the proof it appeared necessary to study non-linear transformations on the energy surface.

DIAGNOSING FAULTY STRUCTURAL HEALTH MONITORING (SHM) IN THE EVENT OF AN AUTOMOBILE ACCIDENT
Creators: name: Cucolotto, Maeve Bruna
Publisher: name: Purdue University Graduate School
Year: 2022
Subjects: Structural engineering

description: Structural health monitoring is more efficient than traditional visual interval-based structural inspection because structural assessments are implemented when a sensor, such as an accelerometer, measures the vibration of the structure and detects any abnormal readings outside of a safety threshold. These vibrations tend to be atypical when there is damage to the structure. Processing the collected data from an accelerometer using Fast Fourier Transformation (FFT) allows for a graphical visualization of visualizing these atypical measurements in the frequency domain. The comparison and analysis of vibration frequency incurred from three different scenarios (damage, no damage, and impact) in the steel truss prototype has resulted in fundamental knowledge necessary to differentiate an abnormality in accelerometer readings resulting from a vehicular crash against one in which there is actual structural damage. The primary outcome of this work will lead to avoiding unnecessary inspection costs due to possible faulty diagnostics and determining the reliability of the structural health monitoring method.

description: We investigate flow properties of immiscible Bose-Einstein condensates composed of two different Zeeman spin states of 87Rb. Spatially overlapping two condensates in the optical trap are prepared by application of a resonant radio frequency pulse, and then the magnetic field gradient is applied in order to produce the atomic flow. We find that the spontaneous multiple domain formation arising from the immiscible nature drastically changes the fluidity. The homogeneously overlapping condensates readily separate under the magnetic field gradient, and they form stable configuration composed of the two layers. In contrast, the relative flow between two condensates are largely suppressed in the case where the magnetic field gradient is applied after spontaneous domain formation.

description: We study the superfluid flow in a quasi-one-dimensional Fermi gas with spatially modulated interactions induced by an optical Feshbach resonance. Due to the competition between the periodicity of the modulated interaction and the nonlinearity of the background interaction, an interesting swallowtail structure emerges in the energy spectrum under appropriate parameters. As the interaction strengths are tuned, the swallowtail structure may disappear, giving rise to various different states on a rich phase diagram. We investigate the spatial distribution of the order parameter and the particle density under various parameters, which are useful for the experimental detection of the interesting phases in these systems.

Hippocampal lesions disrupt decrements but not increments in conditioned stimulus processing

description: Studies recording hippocampal neural activity show widespread registration of events during associative learning. Recent computational models of hippocampal function have stressed its role in attentional processes specified by well-developed modern theories of associative learning. These modeling efforts are largely aimed at accounting for the behavioral outcomes of damage to the hippocampal system in terms of underlying changes in information processing. Two experiments examined the effects of neurotoxic lesions of the hippocampus on changes in attentional processing of a conditioned stimulus (CS) in appetitive Pavlovian conditioning in rats. In Experiment 1, hippocampal lesions eliminated the reduction in associability of a CS usually produced by preexposure to that cue (latent inhibition). In Experiment 2, hippocampal lesions interfered with the loss in associability of a CS normally produced when that CS consistently predicts another event. In contrast, in Experiment 2, hippocampal lesions did not prevent the enhancement of CS associability when a previously consistent predictive relation between two events was made inconsistent. This research supports previous claims that the hippocampus is involved in regulating the processing of CSs in Pavlovian conditioning, and provides new evidence for a hippocampal role in decremental, but not incremental, changes in attention.

description: A binary supermassive black hole loses energy via ejection of stars in a galactic nucleus, until emission of gravitational waves becomes strong enough to induce rapid coalescence. Evolution via the gravitational slingshot requires that stars be continuously supplied to the binary, and it is known that in spherical galaxies the reservoir of such stars is quickly depleted, leading to stalling of the binary at parsec-scale separations. Recent N-body simulations of galaxy mergers and isolated nonspherical galaxies suggest that this stalling may not occur in less idealized systems. However, it remains unclear to what degree these conclusions are affected by collisional relaxation, which is much stronger in the numerical simulations than in real galaxies. In this study, we present a novel Monte Carlo method that can efficiently deal with both collisional and collisionless dynamics, and with galaxy models having arbitrary shapes. We show that without relaxation, the final-parsec problem may be overcome only in triaxial galaxies. Axisymmetry is not enough, but even a moderate departure from axisymmetry is sufficient to keep the binary shrinking. We find that the binary hardening rate is always substantially lower than the maximum possible, "full-loss-cone" rate, and that it decreases with time, but that stellar-dynamical interactions are nevertheless able to drive the binary to coalescence on a timescale <=1 Gyr in any triaxial galaxy.

description: In a superlattice placed in crossed electric and magnetic fields, under certain conditions, the inversion of electron population can appear at which the average energy of electrons is above the middle of the miniband and the effective mass of the electron is negative. This is the implementation of the negative effective mass amplifier and generator (NEMAG) in the superlattice. It can result in the amplification and generation of terahertz radiation even in the absence of negative differential conductivity.

Using the conformal equivalence of $C(H^3)$ and the cylinder $R\times H^3$, we show that, in the adiabatic limit when the metric on $H^3$ is scaled down, classical Yang-Mills dynamics is described by geodesic motion in the infinite-dimensional group manifold $C^\infty (S^2_\infty,G)$ of smooth maps from the boundary 2-sphere $S^2_\infty=\partial H^3$ into the gauge group $G$.

description: We propose a new and robust method to test the consistency of the cosmic evolution given by a cosmological model. It is realized by comparing the combined quantity r_d^CMB/D_V^SN, which is derived from the comoving sound horizon r_d from cosmic microwave background (CMB) measurements and the effective distance D_V derived from low-redshift Type-Ia supernovae (SNe Ia) data, with direct and independent r_d/D_V obtained by baryon acoustic oscillation (BAO) measurements at median redshifts. We apply this test method for the Lambda-CDM and wCDM models, and investigate the consistency of the derived value of r_d/D_V from Planck 2015 and the SN Ia data sets of Union2.1 and JLA (z<1.5), and the r_d/D_V directly given by BAO data from six-degree-field galaxy survey (6dFGS), Sloan Digital Sky Survey Data Release 7 Main Galaxy Survey (SDSS-DR7 MGS), DR11 of SDSS-III, WiggleZ and Ly-alpha forecast surveys from Baryon Oscillation Spectroscopic Data (BOSS) DR-11 over 0.1

description: Schwann cell-axon interactions in the development, maintenance, and regeneration of the normal peripheral nervous system are complex. A previously described transgene-induced insertional mutation (BPFD#36), now referred to as Enervated (Enr), results in disrupted Schwann cell- axon interactions. In this report, after a crush or transection injury to Enr peripheral nerves, we demonstrate impaired nerve regeneration. There are fewer myelinated fibers per mm2 and thinner myelin sheaths surrounding regenerating axons in the nerves of homozygous mutant mice compared to wild type mice at 28 d after crush injury to the sciatic nerve. Abnormal Schwann cell-axon interactions remain in Enr/Enr animals as evidenced by the relatively frequent ultrastructural finding of unmyelinated large diameter axons in the regenerating nerves. Additionally, nerve graft experiments indicate that the impairment in regeneration is due to a Schwann cell defect. Morphologic and morphometric findings in conjunction with molecular analysis of regenerating nerves suggest that the Enr defect causes a disruption in the ability of “early ” Schwann cells to differentiate to a more mature phenotype. In mutant homozygous and wild type nerves at 7 d after crush injury there are similar levels of mRNA for the low-affinity nerve growth factor receptor, but in the mutant homozygous regenerating nerves there is 11-fold less mRNA for glial fibrillary acidic protein, a more mature phenotypic marker of Schwann cells. This Schwann cell differentiation defect likely accounts for both the peripheral neuropathy and impaired nerve regeneration observed in Enr mice.

description: Continuous Casting (CC) is an essential process in the steel industry to transform molten steel into solid product. This process begins with primary cooling (PC) where the molten steel is cooled, and the initial solidification begins. It is important to monitor the process of PC as defects such as thinning of the shell in the mold can lead to breakouts. Key parameters in PC are the mold design, casting condition, and steel composition. In the research conducted, key parameters for PC are investigated to analyze the impact on flow formation and solidification. To optimize mold design, angular taper to the narrow face can be employed to accommodate for any shell shrinkage. Utilizing computational fluid dynamics, a range of mold taper is simulated per the developed solidification model with defined temperature-dependent material properties. When simulated without a taper, significant air gap formation in the corners of the mold is visible due to thermal shrinkage of the shell. This air gap decreases the cooling rate due to the shell’s lack of contact with the cooling mold wall. A parametric study of mold taper ranging from no taper to 3° as well as change in casting conditions, superheat and casting speed, are conducted to analyze the impact of taper with respect to the casting conditions. Per the conditions applied, angular taper between 1° and 2° resulted into reduction of undercooling and overcooling in the corner of the mold which is subjected to cooling from the broad face and narrow face of the cool mold wall. The turbulent flow in the mold region was found to drastically influences the quality of steel produced during continuous casting. The flow itself can lead to surface defects or slag entrainment based on the formation. A high surface wave due to turbulence of the injected melt lead to fluctuations and the instability compromised the quality of the steel produced as well as entrained the slag. To regulate the flow, electromagnetic forces can be applied in the mold, dampening the local turbulent flow. As the electrically conductive molten steel interacts with the induced magnetic field, it reduced the velocity of the steel jet released from the ports of the submerged entry nozzle. Per the simulation-based study conducted increasing the EMBr strength from 2975G to 4350G reduced the peak surface wave height by 59.47% and volume of flux rate of decrease by 4.25%. Additionally, increasing the SEN depth from 110 mm to 350 mm increased the average wave height by 19% and volume of flux rate of decrease by 2.6%. Lastly, increasing the mold width from 1.067 m to 1.50m increased average wave height by 8.71% and volume of flux rate of decrease by 0.9%.

description: The Hamiltonian Mean Field (HMF) model of coupled inertial, Hamiltonian rotors is a prototype for conservative dynamics in systems with long-range interactions. We consider the case where the interactions between the rotors are governed by a network described by a weighted adjacency matrix. By studying the linear stability of the incoherent state, we find that the transition to synchrony occurs at a coupling constant $K$ inversely proportional to the largest eigenvalue of the adjacency matrix. We derive a closed system of equations for a set of local order parameters and use these equations to study the effect of network heterogeneity on the synchronization of the rotors. We find that for values of $K$ just beyond the transition to synchronization the degree of synchronization is highly dependent on the network's heterogeneity, but that for large values of $K$ the degree of synchronization is robust to changes in the heterogeneity of the network's degree distribution. Our results are illustrated with numerical simulations on Erdös-Renyi networks and networks with power-law degree distributions.

In vivo actions of insulin-like growth factor-I (IGF-I) on brain myelination: studies of IGF-I and IGF binding protein-1 (IGFBP-1) transgenic mice

description: To study the effects and mechanisms of insulin-like growth factor I (IGF-I) on brain myelination in vivo, the morphology of myelinated axons and the expression of myelin specific protein genes have been examined in transgenic (Tg) mice that overexpress IGF-I and that those ectopically express IGF binding protein-1 (IGFBP-1), a protein that inhibits IGF-I actions when present in molar excess. Our data show that the percentage of myelinated axons and the thickness of myelin sheaths are significantly increased in IGF-I Tg and decreased in the IGFBP-1 mice. Cerebral cortical proteolipid protein (PLP) and myelin basic protein (MBP) mRNAs consistently exhibit approximately 200% increases in IGF-I Tg mice and approximately 50% decreases in IGFBP-1 Tg mice. The percentage of oligodendrocytes labeled with a PLP cRNA probe in the corpus callosum and cerebral cortex also is increased in IGF-I Tg mice and reduced in IGFBP-1 Tg mice, suggesting that IGF-I promotes oligodendrocyte survival and/or proliferation. The alterations in the number of oligodendrocytes, however, can not completely account for the changes in myelin gene expression. These results strongly indicate that IGF-I increases myelination by increasing the number of myelinated axons and the thickness of myelin sheaths, the latter by mechanisms that involve stimulation of the expression of myelin protein genes and increase of oligodendrocyte number.

description: The latest measurements of rare $b\to s$ decays in the LHCb experiment have led to results in tension with the predictions of the standard model (SM), including a tentative indication of the violation of lepton flavor universality. Assuming that this situation will persist because of new physics, we explore some of the potential consequences in the context of the SM extended with the seesaw mechanism involving right-handed neutrinos plus effective dimension-six lepton-quark operators under the framework of minimal flavor violation. We focus on a couple of such operators which can accommodate the LHCb anomalies and conform to the minimal flavor violation hypothesis in both their lepton and quark parts. We examine specifically the lepton-flavor-violating decays $B\to K^{(*)}\ell\ell'$, $B_s\toϕ\ell\ell'$, $B\to(π,ρ)\ell\ell'$, and $B_{d,s}\to\ell\ell'$, as well as $K_L\to eμ$ and $K\toπeμ$, induced by such operators. The estimated branching fractions of some of these decay modes with $μτ$ in the final states are allowed by the pertinent experimental constraints to reach a few times $10^{-7}$ if other operators do not yield competitive effects. We also look at the implications for $B\to K^{(*)}νν$ and $K\toπνν$, finding that their rates can be a few times larger than their SM values. These results are testable in future experiments.
