Does Race Play a Role in the Robustness of the Flu Vaccine Response in Obese Women?
Creators: name: Patel, Nikita
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Obesity prevalence has increased drastically over the last couple of
decades. Obesity increases an individual’s risk of health complications such as
cardiovascular disease, hypertension, and other chronic conditions. Obesity has
been related to an increased susceptibility to infection and complications from the
influenza virus. In the present study, the immune responses to the influenza
vaccine between races in obese women will be compared by determining the
percent increases in immunoglobulin G subtype levels from pre to post
vaccination. To accomplish this, serum was collected from study participants
and tested for antibody levels pre and post vaccination using an indirect enzyme-linked
immunosorbent assay. For IgG1 and IgG3, average percent increases pre
to post vaccination displayed no difference between African American women
and Caucasian women. IgG2 was not present in detectable levels in the
population studied and was not able to be analyzed. For IgG4, the average
percent increase pre to post vaccination displayed a statistically significant
difference between African American women and Caucasian women. African
Americans had a significantly lower average percent increase in IgG4 pre to post
vaccination compared to Caucasians. This suggests that there may be lower
levels of IgG4 in African American women in general compared to Caucasian
women. Future studies should be conducted to further investigate these
relationships.

description: This paper is devoted to determining the nature of the hard X-ray source IGR J17463-2854 located toward the Galactic bulge. Using data from the INTEGRAL and Chandra X-ray observatories, we show that five point X-ray sources with approximately identical fluxes in the 2-10 keV energy band are detected in the error circle of the object under study. In addition, significant absorption at low energies has been detected in the spectra of all these sources. Based on data from the VVV (VISTA/ESO) infrared Galactic Bulge Survey, we have unambiguously identified three of the five sources, determined the J, H and K magnitudes of the corresponding stars, and obtained upper limits on the fluxes for the remaining two sources. Analysis of the color-magnitude diagrams has shown that one of these objects most likely belongs to a class of rarely encountered objects, symbiotic binary systems (several tens are known with certainty), i.e., low-mass binary systems consisting of a white dwarf and a red giant. Note that all our results were obtained using improved absorption values and an extinction law differing in this direction from the standard one.

The Optimization of Microraft Production and Use for Cell Identification and Sorting
Creators: name: Hinson, Robert
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: Microwell arrays containing magnetic microrafts provide an alternative to fluorescence-activated
cell sorting (FACS) that allows for the sorting of cells using temporal characteristics
and improved viability for adherent cell lines. Making these arrays from thicker layers of
polydimethylsiloxane (PDMS) improved the imaging quality by reducing the sagging of the
array caused by the weight of cell culture media and did not hinder the effectiveness of releasing
the rafts for cell sorting. It was also found that centrifugation of cells in these arrays drastically
reduced the time it took for the cells to sediment into the wells at the desired density and did not
reduce the viability of the cells.
From the Margins: Revisiting Mildred Haun’s Genre and Literary Craft
Creators: name: Martin, Clarke Sheldon
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2017

description: Mildred Haun burst onto the Appalachian literary scene when her 1940 book, The
Hawk’s Done Gone, was published. The work, a collection of ten stories, offers an in-depth and
instructional catalogue of Haun’s native east Tennessee mountain culture through the voice of
Mary Dorthula Kanipe, a respected granny-woman trapped in a patriarchal social structure. The
Hawk’s Done Gone enjoyed favorable reviews at its time of publication, but it quickly slipped
into obscurity. Haun’s short life and complicated relationship with her publisher may have
pushed her voice into the margins during her time, but The Hawk’s Done Gone provides cultural
observation and connection to a way of life and oral tradition that is deserving of attention today.
This paper provides a brief biography of Haun, a discussion of the publication history and
genre of The Hawk’s Done Gone, and a close reading of “Melungeon-Colored,” a part of the
collection that exemplifies many of the themes central to the general body of the work. The
significance of The Hawk’s Done Gone lies as much in what it avoids as what it addresses.
Haun’s craft, especially in reference to her narrator, allows her to present a catalogue of east
Tennessee mountain culture for the instruction of the reader, while her narrator’s awareness of
the audience and selective sharing facilitate not only observation, but also critique.
Metastability effects in strained and stressed SrTiO3 films

description: The sequence of ground states for SrTiO3 film subjected to epitaxial strain as well as to mechanical stress along the [001] and [110] axes is calculated from first principles within the density functional theory. Under the fixed-strain boundary conditions, an increase in the lattice parameter of a substrate results in the $I4cm \to I4/mcm \to Ima2 \to Cm \to Fmm2 \to Ima2$(II) sequence of ground states. Under the fixed-stress boundary conditions, the phase sequence is different and depends on how the stress is applied. It is revealed that the simultaneous presence of competing ferroelectric and antiferrodistortive instabilities in SrTiO3 gives rise to the appearance of metastable phases, whose number increases dramatically under the fixed-stress conditions. In the metastable phases, the octahedral rotation patterns are shown to differ substantially from those in the ground state. It is suggested that in systems with competing instabilities, each polar phase has its optimal octahedral rotation pattern which stabilizes this phase and creates a potential barrier preventing this phase to be transformed into other structures.

On December 6th and 7th, 2022, the Tłı̨chǫ Government Department of Culture and Lands Protection (DCLP) hosted a two day “Night at the Museum Research Expo.” This event was originally thought of as a way to introduce the Tłı̨chǫ Cultural Commons archival work to the public in Behchokǫ̀, but then grew into a larger event that showcased many aspects of Tłı̨chǫ research. Over two days, we gathered as researchers, Elders, and community members within the community museum space at Kǫ̀ Gocho (Sportsplex) in Behchokǫ̀ to celebrate, discuss, and present research being done in Tłı̨chǫ lands and culture.

This booklet details these research events and represents the first of a research series documenting the archival work being done. It was inspired by the example set by our first sharing circle (detailed in this booklet) and the emphasis that the Elders put on documenting their knowledge. Suggestions for booklets as tools for documenting our research and other knowledge held within the archive were voiced by Mike Nitsiza (Whatì), who told us of how he made 55 booklets that share stories and traditional practices, and Alphonse Apples (Gamètì) who also stressed the importance of documenting knowledge, and he too suggested the use of booklets to communicate our work and Tłı̨chǫ knowledge to the next generations.
Predicting Personality Coherence across Personality Trait Categories: An Idiographic Analysis of Self-Knowledge and Situational Construals

Year: 2022

description: Our proposed research seeks to fill a gap in the contemporary personality science literature. It is best understood by reference to two recent advances: the recognition that (1) a multiplicity of underlying psychological processes contributes to any given dispositional tendency (Wood, Gardner, & Harms, 2015, Psy. Rev.), with explanation of such tendencies thus requiring reference to a system of underlying causal mechanisms (Baumert et al., EJP; Cervone, 1997, Psy. Sci.), and that (2) intra-individual patterns of personality expression may vary from inter-individual patterns observed in the population (Borsboom, Mellenberg, and van Heerden, 2003, Psy. Rev.); personality dynamics, in other words, may not be ergodic (Fisher, Medaglia, & Jeronimus, 2018, PNAS). We pursue this goal by employing the conceptual and methodological tools of the KAPA model of personality architecture (Cervone, 2004, Psy. Rev.). Novel idiographically-tailored research methods were developed for use in two studies designed to address the gaps in the literature described above. In these methods, we identify positively- and negatively-valenced beliefs about the self (i.e., self-schemas) through open-ended narrative methods in which participants describe their personal strengths and weaknesses. We identify situational contexts that activate these knowledge structures through a categorization task designed to identify circumstances that, according to the situational construals of each participant, are linked to their previously-identified positive and negative personal attributes. In combination, the procedures employed yield idiographic person-in-context “maps.” Our central expected result is that people will report consistent action tendencies across contexts that they map to their self-schemas, irrespective of whether these mappings, at the level of the individual case, correspond to the structure of nomothetic trait categories. As of 4/15/2019, we have run and analyzed data only for Study 1. Study 2 and any subsequent analyses have yet to be fully analyzed.

description: Almost all superluminous supernovae (SLSNe) whose peak magnitudes are $\lesssim -21$ mag can be explained by the $^{56}$Ni-powered model, magnetar-powered (highly magnetized pulsar) model or ejecta-circumstellar medium (CSM) interaction model. Recently, iPTF13ehe challenges these energy-source models, because the spectral analysis shows that $\sim 2.5M_\odot$ of $^{56}$Ni have been synthesized but are inadequate to power the peak bolometric emission of iPTF13ehe, while the rebrightening of the late-time light-curve (LC) and the H$α$ emission lines indicate that the ejecta-CSM interaction must play a key role in powering the late-time LC. Here we propose a triple-energy-source model, in which a magnetar together with some amount ($\lesssim 2.5M_\odot$) of $^{56}$Ni may power the early LC of iPTF13ehe while the late-time rebrightening can be quantitatively explained by an ejecta-CSM interaction. Furthermore, we suggest that iPTF13ehe is a genuine core-collapse supernova rather than a pulsational pair-instability supernova candidate. Further studies on similar SLSNe in the future would eventually shed light on their explosion and energy-source mechanisms.

description: We report on a numerical study of real-time dynamics of electromagnetically interacting chirally imbalanced lattice Dirac fermions within the classical statistical field theory approach. Namely, we perform exact simulations of the real-time quantum evolution of fermionic fields coupled to classical electromagnetic fields, which are in turn coupled to the vacuum expectation value of the fermionic electric current. We use Wilson-Dirac Hamiltonian for fermions, and non-compact action for the gauge field. In general, we observe that the backreaction of fermions on the electromagnetic field prevents the system from acquiring chirality imbalance. In the case of chirality pumping in parallel electric and magnetic fields, electric field is screened by the produced on-shell fermions and the accumulation of chirality is hence stopped. In the case of evolution with initially present chirality imbalance, axial charge tends to transform to helicity of electromagnetic field. By performing simulations on large lattices we show that in most cases this decay process is accompanied by the inverse cascade phenomenon which transfers energy from short-wavelength to long-wavelength electromagnetic fields. In some simulations, however, we observe a very clear signature of inverse cascade for the helical magnetic fields which is not accompanied by the axial charge decay. This suggests that the relation between inverse cascade and axial charge decay is not as straightforward as predicted by the simplest form of anomalous Maxwell equations.

Detection of magnetic fields in both B-type components of the $ε$ Lupi system: a new constraint on the origin of fossil fields?

description: High-resolution circular spectropolarimetric observations, obtained with ESPaDOnS in the context of the BinaMIcS Large Program, have revealed a magnetic field in the B3V secondary component of the SB2 binary system $ε$ Lupi (B2/B3). As the B2V primary is already known to be magnetic, this is the first detection of a magnetic field in both components of an early-type binary system. The longitudinal magnetic field of the primary is $\sim -200$ G; that of the secondary $\sim +100$ G. Observations can be approximately reproduced by a model assuming the magnetic axes of the two stars are anti-aligned, and roughly parallel to their respective rotation axes. Estimated magnetospheric radii indicate a high probability that their magnetospheres are interacting. As many of the arguments for the different proposed formation scenarios of fossil magnetic fields rely upon evidence drawn from investigations of close binaries, in particular the rarity of magnetic ABO stars in close binaries and the previous absence of any known close binary with two magnetic, massive stars, this discovery may be an important new constraint on the origin of fossil magnetic fields.

description: In this letter, we outline a methodology to calculate microscopically mass and charge distributions of spontaneous fission yields. We combine the multi-dimensional minimization of collective action for fission with stochastic Langevin dynamics to track the relevant fission paths from the ground-state configuration up to scission. The nuclear potential energy and collective inertia governing the tunneling motion are obtained with nuclear density functional theory in the collective space of shape deformations and pairing. We obtain a quantitative agreement with experimental data and find that both the charge and mass distributions in the spontaneous fission of 240Pu are sensitive both to the dissipation in collective motion and to adiabatic characteristics.

EXPLORATION OF PARAMETER SPACE OF TWO ACTIVE CONTOUR ALGORITHMS IN THE SEGMENTATION OF MINI-PIG BURN WOUNDS
Creators: name: Anand, Keerthi
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: Traditional methods of burn wound analysis rely on subjective classification of shape and variable estimation of size using the rule-of-nines. For partial thickness burns, where the standard method leads to differing prognoses, it was hypothesized that the use of active contour algorithms could aid in automatic segmentation and quantitative analysis. Previous work was conducted, comparing burn wounds taken with a DSLR to a Microsoft Kinect V2 and quantifying an algorithm’s ability to distinguish the region of a burn wound on a pig. Image analysis utilizing the Edge and Chan-Vese Active Contour algorithms found the Dice-coefficient, a measure of how well a computer-generated trace aligned with a predetermined human trace, to be artificially high. It was suspected that the inflation was due to a favorable initial mask being provided to the analysis software. It was hypothesized that a difference would be noted in segmentation behavior of the two algorithms and that providing a less favorable initial trace would not yield high Dice coefficients. In order to examine the effects of starting masks on segmentation outputs and measure the generalized performance of these algorithms, in this study, we incrementally modified parameters such as the contraction bias, iteration, and starting mask, to find a parameter space that would yield repeatable, high accuracy predictions of burn wound regions. Results showed a significant difference in the performance of the algorithms and choice of starting masks at thresholds for Dice’s coefficients above 0.8 and that choice of starting mask shape and size bias segmentation. By developing an automated system to determine the best parameter set not subject to artificially high Dice’s coefficients, computers can aid physicians in accurate diagnosis and treatment of partial thickness burn wounds.

description: Prudent walks are self-avoiding walks which cannot step towards an already occupied vertex. We introduce a new model of adsorbing prudent walks on the square lattice, which start on an impenetrable surface and accrue a fugacity $a$ with each step along the surface. These are different to other exactly solved models of polymer adsorption, like Dyck paths, Motzkin paths and partially-directed walks, in that they are not trivially directed - they are able to step in all lattice directions. We calculate the generating functions, free energies and surface densities for this model and observe a first-order adsorption transition at the critical value of the surface interaction.

description: Grounded in our commitment to support preservice teachers (PSTs) in an urban elementary teacher education program to develop anti-bias pedagogies, we engaged in a design-based study aimed at enacting critical conversations about texts that foster dialogue about power and privilege. In this analysis, we explore how PSTs engaged with children during discretionary moments within critical conversations in their field placements. We asked: What generative orientations are visible in PSTs’ analysis of and reflection on their facilitation of critical conversations with children? Findings reveal that PSTs who extended dialogue during these moments in critical conversations—rather than avoiding or ignoring children’s contributions—displayed an orientation toward seeing children as sensemakers; flexibly responded to encourage dialogue; and recognized the value of feeling uncomfortable.

description: We perform a systematical analysis of the spin Hall effect (SHE) in the Cu alloys doped with a series of 5d elements, by the combined approach of density functional theory and Hartree-Fock approximation. We find that not only the spin orbit interactions (SOI) in both the 5d and 6p orbitals, but also the local correlations in the 5d orbitals of the impurities, are decisive on the sign of the spin Hall angle (SHA). Including all of these three factors properly, we predict the SHA for each alloy in the series. The signs of CuIr and CuPt are sensitive to perturbation of the local correlations. This observation is favorable for controlling the sign of the transverse spin Hall voltage.

description: Background: Developing, monitoring, and reporting of fidelity are essential and integral components to the design of randomised controlled trials (RCTs) in stroke and aphasia. Treatment fidelity refers to the degree to which an intervention is delivered as intended and is directly related to the quality of the evidence generated by RCTs. Clear documentation of treatment fidelity in trials assists in the evaluation of the clinical implications of potential benefits attributed to the intervention. Consideration of the implementation requirements of a research-based intervention as intended in a clinical context is necessary to achieve similar outcomes for a clinical population. Despite this, treatment fidelity is rarely reported in RCTs of aphasia intervention. Aim: To describe fidelity strategies and develop core recommendations for developing, monitoring, and reporting of fidelity in aphasia intervention RCTs. Scope: Relevant conceptual frameworks were considered. The Behaviour Change Consortium comprehensive framework of fidelity was adopted. It includes five areas: study design, training providers, delivery of treatment, treatment receipt, and treatment enactment. We explored fidelity in RCTs with a range of complex aphasia interventions (e.g., ASK, Big CACTUS, COMPARE, FCET2EC, POLAR, SUPERB, and VERSE) and described how different trial design factors (e.g., phase of trial, explanatory vs. pragmatic, number and location of sites, and number and type of treatment providers) influenced the fidelity strategies chosen. Strategies were mapped onto the five areas of the fidelity framework with a detailed exploration of how fidelity criteria were developed, measured, and monitored throughout each trial. This information was synthesised into a set of core recommendations to guide aphasia researchers towards the adequate measurement, capture, and reporting of fidelity within future aphasia intervention studies. Conclusions/Recommendations: Treatment fidelity should be a core consideration in planning an intervention trial, a concept that goes beyond treatment adherence alone. A range of strategies should be selected depending on the phase and design of the trial being undertaken and appropriate investment of time and costs should be considered.

description: The prediction of phenotypic traits using high-density genomic data has many applications such as the selection of plants and animals of commercial interest; and it is expected to play an increasing role in medical diagnostics. Statistical models used for this task are usually tested using cross-validation, which implicitly assumes that new individuals (whose phenotypes we would like to predict) originate from the same population the genomic prediction model is trained on. In this paper we propose an approach based on clustering and resampling to investigate the effect of increasing genetic distance between training and target populations when predicting quantitative traits. This is important for plant and animal genetics, where genomic selection programs rely on the precision of predictions in future rounds of breeding. Therefore, estimating how quickly predictive accuracy decays is important in deciding which training population to use and how often the model has to be recalibrated. We find that the correlation between true and predicted values decays approximately linearly with respect to either $\F$ or mean kinship between the training and the target populations. We illustrate this relationship using simulations and a collection of data sets from mice, wheat and human genetics.

description: In recent years, researchers and practitioners have developed predictive algorithms as tools to improve human judgment and decision-making. Algorithms consistently perform well on a variety of judgment-related tasks, but people generally mistrust their advice. Here, we propose that trust in algorithm-generated advice depends on algorithmic decision speed: people judge slow algorithmic predictions as less accurate and they are less willing to rely on them (Studies 1-2). For humans, we found the opposite pattern: slow predictions were seen as more accurate and people were more willing to use them (Studies 1-2). Additionally, slow predictions generated by algorithms were more likely to lead people to ask for additional human advice – a potentially detrimental behavioral tendency given algorithm superiority (Study 3). Further, people were more likely to disregard slowly generated algorithm advice (in favor of quickly generated advice); and the negative effects of slow decision speed were stronger for those who were unfamiliar with the prediction context (Study 4). The results underscore the value of decision speed as a cue, even in non-humans, and provide insight into how decision time influences human-computer interactions.
Nationhood in Germany since 1945

description: The German nation went through momentous change in the twentieth century. The first two decades saw a country whose populace believed in the Sonderweg, the “special path” that Germany would take to glory—a path which was taken through military might and conquest. Germany’s defeat in the First World War did little to change the minds of the people, who had lived through German exceptionalism since German unification in 1871. The National Socialists seized the opportunity to blame Germany’s loss in the war on the many minority groups: Jews, Catholics, Poles and other Slavs, to name a few. The German nation was not just militaristic, but racist as well: a true German had to be of Aryan stock. The Germans were rabidly patriotic; the national symbol, the swastika, adorned flags and public buildings across the nation. The horrors of war changed the minds of the Germans. As the country lay in ruins following a second defeat, many felt lost. The state was abolished; there was no Germany to belong to, no military to admire, no flag to fly. Without the Reich, how would Germany develop a new state? Would it be the same as the old one? Would Germans resent the victorious allies? Would they want to democratize? This thesis paper will explore the development of German nationhood from the defeat of the Third Reich in 1945 to today.

description: We show that the bipartite logarithmic entanglement negativity (EN) of quantum spin models obeys an area law at all nonzero temperatures. We develop numerical linked cluster (NLC) expansions for the `area-law' logarithmic entanglement negativity as a function of temperature and other parameters. For one-dimensional models the results of NLC are compared with exact diagonalization on finite systems and are found to agree very well. The NLC results are also obtained for two dimensional XXZ and transverse-field Ising models. In all cases, we find a sudden onset (or sudden death) of negativity at a finite temperature above which the negativity is zero. We use perturbation theory to develop a physical picture for this sudden onset (or sudden death). The onset of EN or its magnitude are insensitive to classical finite-temperature phase transitions, supporting the argument for absence of any role of quantum mechanics at such transitions. On approach to a quantum critical point at $T=0$, negativity shows critical scaling in size and temperature.

description: Desde un inicio tenía la convicción de elegir un tema relacionado al autismo en adultos, por mi profundo interés en la materia y a partir de mi propia condición autista. En la actualidad, no existe un amplio acervo bibliográfico sobre el autismo en la población adulta y menos aún, escritos donde uno pueda acceder a descripciones en primera persona de adultos autistas dialogando sobre sí mismos, puesto que la mayoría de textos se concentran en las conclusiones de investigaciones, sobre todo, en poblaciones infantiles para la identificación de características diagnósticas, abordajes precoces o intervenciones en etapa escolar referentes al aspecto socioemocional y niveles de aprendizaje.
 Por otro lado, mi motivación para desarrollar el tema va en relación a mi deseo de aportar al campo de investigación, dado que el adulto autista estaría quedando camuflado entre la población típica, siendo difícilmente identificado y algunas de sus características singulares podrían estar pasando muy desapercibidas en la edad adulta, como sus afectos, sus formas de procesamiento cognitivo y sensorial, sus profundos intereses, sus maneras de vincularse afectiva y socialmente, sus formas de comunicarse, comportarse y captar la información de su entorno.

description: Frustrated transition metal compounds in which spin-orbit coupling (SOC) and electron correlation work together have attracted much attention recently. In the case of 5$d$ transition metals, where SOC is large, $j_\text{eff}=1/2$ bands near the Fermi level are thought to encompass the essential physics of the material, potentially leading to a concrete realization of exotic magnetic phases such as the Kitaev spin liquid. Here we derive a spin model on a triangular lattice based on $j_\text{eff} = 1/2$ pseudospins that interact via antiferromagnetic Heisenberg ($J$) and Kitaev ($K$) exchanges, and crucially, an anisotropic $(Γ)$ exchange. Our classical analysis of the spin model reveals that, in addition to small regions of 120$^\circ$, $\mathbb{Z}_2$ / dual-$\mathbb{Z}_2$ vortex crystal and nematic phases, the stripy and ferromagnetic phases dominate the $J$-$K$-$Γ$ phase diagram. We apply our model to the 5$d$ transition metal compound, Ba$_3$IrTi$_2$O$_9$, in which the Ir$^{4+}$ ions form layered two-dimensional triangular lattices. We compute the band structure and nearest-neighbor hopping parameters using ab-initio calculations. By combining our ab-initio and classical analyses, we predict that Ba$_3$IrTi$_2$O$_9$ has a stripy ordered magnetic ground state.

description: In this paper we propose two strongly convergent parallel hybrid iterative methods for finding a common element of the set of fixed points of a family of quasi $ϕ$-asymptotically nonexpansive mappings $\{F(S_j)\}_{j=1}^N$, the set of solutions of variational inequalities $\{VI(A_i,C)\}_{i=1}^M$ and the set of solutions of equilibrium problems $\{EP(f_k)\}_{k=1}^K$ in uniformly smooth and 2-uniformly convex Banach spaces. A numerical experiment is given to verify the efficiency of the proposed parallel algorithms.

description: Previous research suggests that humans are not reliable judges of the amount of synchrony between individuals who are moving their bodies, but that the presence of more synchronicity enhanced how much the observers enjoyed watching the movements. This study aims to ascertain whether humans really are poor judges of synchrony, or successful quantification of synchrony is dependent on kinematic features of the movement, aesthetic judgements made by the perceiver, or perhaps even perceiver traits.
An unexpected role for CXCL5 in the pathophysiological response to a Western diet

description: Atherosclerosis is a chronic inflammatory disease that results in the build-up of lipid filled macrophages, called foam cells, which contribute to the formation of arterial plaque.  These plaques can obstruct blood flow which can lead to serious complications, such as stroke, heart attack, and aneurysms. CXCL5 is a circulating chemokine involved in the recruitment of monocytes in acute inflammatory conditions, however, the role that CXCL5 plays in chronic cardiovascular inflammatory diseases is not defined. Our previous clinical studies demonstrated that circulating CXCL5 levels and atherosclerosis severity are inversely proportional, suggesting a possible protective role for CXCL5. We hypothesize that lower levels of CXCL5 will lead to more severe disease pathology and that CXCL5 plays an atheroprotective role by altering macrophage metabolism and polarization. To investigate the in vivo repercussions of CXCL5 depletion, we challenged wild-type and Cxcl5-/- mice with high-fat diet for 16-weeks. Given these mice were not on an atheroprone background, as expected, we did not see any evidence of atherosclerosis in isolated aortas from mice of either genotype. Surprisingly, the Western diet did not increase cholesterol levels to the same extent in Cxcl5-/- mice compared to wild-type mice, however, cardiac function was decreased in Cxcl5-/- mice after 16 weeks of the diet. These preliminary findings suggest that CXCL5 does play a broad role in the pathophysiological response to a high fat, high cholesterol diet.

description: Compounds of low lattice thermal conductivity (LTC) are essential for seeking thermoelectric materials with high conversion efficiency. Some strategies have been used to decrease LTC. However, such trials have yielded successes only within a limited exploration space. Here we report the virtual screening of a library containing 54,779 compounds. Our strategy is to search the library through Bayesian optimization using for the initial data the LTC obtained from first-principles anharmonic lattice dynamics calculations for a set of 101 compounds. We discovered 221 materials with very low LTC. Two of them have even an electronic band gap < 1 eV, what makes them exceptional candidates for thermoelectric applications. In addition to those newly discovered thermoelectric materials, the present strategy is believed to be powerful for many other applications in which chemistry of materials are required to be optimized.

description: The number of well-studied early-type pre-main-sequence objects is very limited, hampering the study of massive star formation from an observational point of view. Here, we present the results of VLT/FORS2 spectropolarimetric and VLT/X-shooter spectroscopic observations of two recently recognised candidate Herbig Be stars, PDS 27 and PDS 37. Through analysis of spectral lines and photometry, we find that these two objects are hot, 17500 $\pm$ 3500~K, have large radii, 17.0 $\pm$ 4.0 and 25.8 $\pm$ 5.0~${\rm R}_\odot$, and are very massive, 15.3 (+5.4, -4.4) and 21.1 (+11.0, -5.3)~M$_{\odot}$ for PDS 27 and PDS 37, respectively. This suggests that these two objects are very young in their evolution and may become O-type stars. Their youth is supported by their high accretion rates of the order of $10^{-3}$--$10^{-4.5}~{\rm M}_\odot$/yr. A change in linear polarisation across the absorption component of H$α$ is detected in both objects. This change indicates that the circumstellar environment close to the star, at scales of several stellar radii, has a flattened structure, which we identify as an inner accretion disk. Strong variability is seen in both objects in many lines as further indication of an active circumstellar environment.

description: In the context of modern pedagogy, educators and academics have been placing greater emphasis on the value of Learning-By-Doing (LBD) and 21st Century Skills. This thesis presents an exploration of the existing approach to LBD practices and 21st Century Skills based on research conducted at one of the premier higher education institutions for engineering in the United Arab Emirates (UAE). This thesis presents an analysis of the current understanding of LBD from the viewpoint of the institution’s leadership and faculty, in response to the overall research question: What constructively aligned Learning-By-Doing (LBD) pedagogical model, incorporating 21st Century Skills, can be developed for enhancing the teaching of engineering at HCT, UAE?

It seeks to identify the LBD practices that are being successfully implemented and the 21st Century Skills that are being taught and assessed, drawing substantially from the vantage point of instructors and students. By exploring these areas in a top-ranked institution in the UAE, this thesis seeks to cast a broader light on the perspectives and practices of similar universities and engineering programs in the Emirates. The study employed a mixed methods approach in which students participated in an online survey while the engineering dean and instructors took part in open-ended, semi-structured interviews. The findings from the two sets of data collection activities were merged resulting in the emergence of themes, which were then used as the basis for formulating five basic principles. These principles were used to guide the development of a four-stage (Explore, Do, Reflect and Apply) LBD learning model. Rooted in the literature of Kolb, Dewey and Lewin, this LBD Model provides extensive structure and specificity for curriculum development, lesson planning, teaching and assessment of content, and professional learning, with the potential to lead an inclusive implementation of LBD practices and 21st Century Skills going forward.
