National Association of Women Artists 81st Anniversary Exhibition, May 14th thru May 31st, 1970
Creators: name: No Name Supplied
Publisher: name: No Publisher Supplied
Year: 1970

description: The National Association of Women Artists (NAWA) was established in 1889 and is the oldest professional women's fine arts organization in the United States. NAWA's mission is to promote awareness of, and interest in, visual art created by women in the United States. As part of this effort NAWA holds an annual exhibition of works by members of the association and publishes an exhibition catalog to accompany or commemorate the annual exhibitions. These catalogs not only function as an exhibition catalog, but also as a document that summarizes the structure, membership, and activities of the association.Information that can be found in these catalogs includes lists of officers, members of the executive board and committees, prize winners, lists of exhibitor and members, and images of some of the artwork exhibited. Catalogs from the 2000s also include information on NAWA events and activities beyond the annual exhibition.Please note that the numbering of the annual catalogs was adjusted in 1960 and again in 1971. For example, NAWA designated the annual exhibition in 1960 as the 70th Anniversary Exhibition after 1959 was the 67th Annual Exhibition. These adjustments appear to have been made to reflect the date of the founding of the association, so that, by 1989, the annual exhibition commemorated the 100-year anniversary of the founding of NAWA in 1889.

description: Most regions of the Kingdom of Saudi Arabia (KSA) can be considered extreme environments for biological growth, this geography includes regions of elevated light and temperatures, extreme pH, hyper salinity, and heavy metals. Despite these inhospitable conditions, photosynthetic organisms can survive, so long as some irrigation is provided, and we have found that photosynthetic microorganisms are readily isolatable from the local context. As algal biodiversity has generally been underexplored in the KSA, we decided to develop a living libraryof locally isolated algal species from this region for all algal biotechnology and phycology applications. We have been collecting environmental samples from desert regions, hot springs, the Red Sea, as well as volcanic areas, and so far, we have identified by morphology two potential Chlamydomonas strains from different environments within the KSA. Sequencing and growth profiles in simulated weather conditions using photobioreactors are being carried out. The growth will be benchmarked in two control conditions, constant light, 12 h:12 h light: dark, both at 25°C and 325 μmol photons m−2 s−1, and 4 different temperature and light conditions that each represents one of the four seasons from each of February (Winter), May (Spring), August (Summer), and November (Autumn) in Thuwal, Saudi Arabia. Upon genetic confirmation of these isolates as Chlamydomonas, they will be deposited at the Chlamydomonas resource center and shared with the global community as alternative strains from this unusual environment.

description: This study examines physics students' evaluations of identical, video-recorded lectures performed by female and male actors playing the role of professors. The results indicate that evaluations by male students show statistically significant overall biases with male professors rated more positively than female professors. Female students tended to be egalitarian, except in two areas. Female students evaluated female professors' interpersonal/communicative skills more positively than male professors'. They evaluated female professors' scientific knowledge and skills less positively than that of male professors just as male students did. These findings are relevant to two areas of research on bias in evaluation: rater-ratee similarity bias and stereotype confirmation bias. Results from this study have important implications for efforts focused on educating students and mentoring faculty members in order to increase the representation of women in the physical sciences.

description: Terpenoids are a diverse class of natural compounds with a wide range of applications in flavoring, fragrances, and medicine. However, many of these compounds are sourced from slow-growing, rare, or endangered plants. Heterologous production of terpenoids in engineered microbes offers a promising alternative which is scalable and readily accessible when production is required. Here, we investigated the production of heterologous sesquiterpenoids with applications as fragrances from Chlamydomonas reinhardtii. To channel cellular carbon towards sesquiterpenoids, we investigated the role that perturbation of the carotenoid pathway has on cytoplasmic terpenoids by expressing a β-carotene ketolase (BKT) which is known to produce ketocarotenoids. We coupled this with knock down of squalene synthase (SQS) to reduce metabolic pull on the sesquiterpene precursor farnesyl diphosphate (FDP). These modifications resulted in a synergistic effect on heterologous sesquiterpenoid production, significantly increasing patchoulol (C15-OH) production from 5.6 ± 1.4 fg/cell to 183 ± 23 fg/cell using a cytosolically localized patchoulol synthase. To further expand the range of heterologous sesquiterpenoids produced, we expressed and compared 22 sesquiterpenoid synthases from various organisms in this engineered strain of C. reinhardtii. This broad in vivo screening of enzyme variants in C. reinhardtii was facilitated by standardized in silico designs and large-scale DNA synthesis. Synthases producing aristolochene (n=4), guaiene (n=6), santalene (n=3), valencene (n=1), valerianol (n=1), zizaene (n=2), cadinol (n=1), and bisabolol (n=1) were expressed and their terpene products quantified to identify the optimal synthase for each. Our findings suggest that metabolic engineering in C. reinhardtii can be used to produce sesquiterpenoids from CO2, reducing the need to source these compounds from their natural context. This research could have implications for the fragrance, flavor, and pharmaceutical industries.

Subjects: BeONE

description: The initial plan of an integrated, easily accessible platform for both sharing, visualising and analysing data was not possible due to lack of time, COVID-19, personnel changes and delays in the similar concurrent Danish project SOFI. Therefore, the final solution became a backend independent dashboard, which is possible to get locally on your computer. The input is the BeONE JSON format created in WP3. Furthermore, a datahub was developed, which needs a backend in the form of a MongoDB (database). In this deliverable the datahub will be described and in the following deliverables 4.2 and 4.3 the dashboard will also be described.
A Comprehensive Framework for Studying $W'$ and $Z'$ Bosons at Hadron Colliders with Automated Jet Veto Resummation

description: The production of high-mass, color-singlet particles in hadron colliders is universally accompanied by initial state QCD radiation that is predominantly soft with respect to the hard process scale $Q$ and/or collinear with respect to the beam axis. At TeV-scale colliders, this is in contrast to top quark and multijet processes, which, by definition, are hard and central. Consequently, vetoing events with jets possessing transverse momenta above $p_T^{\rm Veto}$ in searches for new color-singlet states can efficiently reduce non-singlet backgrounds, thereby increasing experimental sensitivity. To quantify this generic observation, we investigate the production and leptonic decay of a Sequential Standard Model $W'$ boson at the 13 TeV LHC. We systematically consider signal and background processes at next-to-leading-order (NLO) in QCD with parton shower (PS) matching; for color-singlet channels, we resum Sudakov logarithms of the form $α_s^j(p_T^{\rm Veto})\log^k(Q/p_T^{\rm Veto})$ up to next-to-next-to-leading logarithmic accuracy (NNLL) with NLO matching. We obtain our results using the MadGraph5aMC@NLO and MadGraph5aMC@NLO-SCET frameworks, respectively. Associated FeynRules model files capable of handling NLO+PS- and NLO+NNLL-accurate computations are publicly available. We find that within their given uncertainties, both the NLO+PS and NLO+NNLL(veto) calculations give accurate and consistent predictions. Consequently, jet vetoes applied to color-singlet processes can be reliably modeled at the NLO+PS level. With respect to a $b$-jet veto of $p_{T}^{\rm Veto} = 30$ GeV, flavor-agnostic vetoes of $p_{T}^{\rm Veto} = 30-40$ GeV can further reduce single top and $t\overline{t}$ rates by a factor of 2-50 at a mild cost of the signal rate. Jet vetoes can increase signal-to-noise ratios by roughly 10\% for light $W'$ boson masses of 30-50 GeV and 25\%-250\% for masses of 300-800 GeV.

A COMPARATIVE EVALUATION OF TELBS ROBUST REGRESSION METHODS
Creators: name: Amelia, Grace Evans

Subjects: Linear regression, outliers, influential points, leverage points, robust regression

description: Linear regression is a widely used statistical model for assessing the impact of explanatory variables on a response variable, with applications spanning across fields such as social sciences, environmental studies, and biomedical research. Conventionally, ordinary least squares (OLS) estimation has been the go-to method for regression analysis. However, the presence of outliers can significantly skew OLS parameter estimates.

This paper delves into the intricacies of outliers, influential points, and leverage points in regression analysis, shedding light on their potential impact on parameter estimation. Outliers, whether in Y-space, X-space, or both, can distort the robustness of OLS estimations. Leverage points, often overlooked in standard residual plots, may exert substantial influence on regression coefficients. To address these challenges, a range of robust regression methods has been developed, including M estimation, MM estimation, LTS, S estimation, and the recently developed TELBS robust estimation. Section 2 provides an overview of these techniques. Robust regression approaches offer the means to estimate model parameters that either mitigate or exclude the influence of outliers, safeguarding against significant parameter distortions that OLS may encounter. Robust estimators are assessed in terms of breakdown point and asymptotic efficiency, crucial for evaluating the trade-off between robustness and data variability. While the application of robust regression has garnered traction in diverse fields, including sociology, political science, chemistry, and biology, its full adoption across all disciplines is an ongoing process

description: Atomic sized two-level systems (TLSs) in amorphous dielectrics are known as a major source of loss in superconducting devices. In addition, individual TLS are known to induce large frequency shifts due to strong coupling to the devices. However, in the presence of a broad ensemble of TLSs these shifts are symmetrically canceled out and not observed in a typical single-tone spectroscopy experiment. We introduce a two-tone spectroscopy on the normal modes of a pair of coupled superconducting coplanar waveguide resonators to reveal this effect. Together with an appropriate saturation model this enables us to extract the average single-photon Rabi frequency of dominant TLSs to be $Ω_0/2π\approx 79 $ kHz. At high photon numbers we observe an enhanced frequency shift due to nonlinear kinetic inductance when using the two-tone method and estimate the value of the nonlinear coefficient as $K/2π\approx -1\times 10^{-4}$ Hz/photon. Furthermore, the life-time of each resonance can be controlled (increased) by pumping of the other mode as demonstrated both experimentally and theoretically.

description: The comparative study of the catalytic behavior of K-modified CoMoS2-catalysts supported on Al2O3, carbon covered alumina (CCA) and graphene coated alumina (GCA containing 0.4, 1.2, and 1.7% of graphene) in synthesis gas and ethanol conversion (separately) to higher alcohols (HAS) and other oxygenates has been carried out. The supports and catalysts were characterized by N2 adsorption-desorption isotherms, pyridine adsorption, SEM, EDX, and TEM. In HAS from syngas, the catalyst supported on GCA materials showed better catalytic performances than the catalysts supported on alumina and carbon coated alumina (Cat-GCA > Cat-CCA > Cat-Al2O3). The spectroscopic results have established that the homogenous uniform coating of alumina by graphene nanosheets follows the order: GCA1 (1.7%) > GCA2 (1.2%) > GCA3 (0.4%). The yield of ethanol has a positive correlation with graphene wt. % in GCA. In ethanol conversion, graphene attenuate the interaction of the support/active site KCoMoS2 and with it its selectivity toward dehydrogenation/condensation reactions. The GCA1 supported catalyst exhibits low activity for the water–gas shift (WGS) reaction compared to its counterpart. Explanations of the observed phenomena have been suggested.

description: We study the ac anomalous Hall conductivity $σ_{xy}(ω)$ of a Weyl semimetal with broken time-reversal symmetry. Even in the absence of free carriers these materials exhibit a "universal" anomalous Hall response determined solely by the locations of the Weyl nodes. We show that the free carriers, which are generically present in an undoped Weyl semimetal, give an additional contribution to the ac Hall conductivity. We elucidate the physical mechanism of the effect and develop a microscopic theory of the free carrier contribution to $σ_{xy}(ω)$. The latter can be expressed in terms of a small number of parameters (the electron velocity matrix, the Fermi energy $μ$, and the "tilt" of the Weyl cone). The resulting $σ_{xy}(ω)$ has resonant features at $ω\sim 2 μ$ which may be used to separate the free carrier response from the filled-band response using, for example, Kerr effect measurements. This may serve as diagnostic tool to characterize the doping of individual valleys.

description: This study investigates the thermal stressing characteristics of hydrocarbon fuels to develop thermally stable fuels for supersonic vehicle applications. The thermal stability characteristics of two multicomponent hydrocarbon fuels, namely F-1 and F-2 fuels, under subcritical and supercritical conditions, are examined for a wide range of temperatures (30–500 °C) and pressures (15–50 bar) using a semi-batch reactor. Various analysis techniques, such as UV-Vis spectrophotometry, ASTM D86 distillation, gas chromatography, scanning electron microscopy (SEM), etc., are used to characterize the feed and product properties. The study showed that the fuels are reasonably stable up to around 400 °C and above 40 bar pressure. The stability of the fuels is relatively less under subcritical pressure at elevated temperatures. The amount of gum formation increased with the increase of both temperature and pressure parameters. Further, the SEM analysis showed oval-shaped and ribbon-like structures in the solid deposits. The present investigation may be useful in developing an appropriate fuel for regenerative cooling in supersonic applications.

description: At $z=1-3$, the formation of new stars is dominated by dusty galaxies whose far-IR emission indicates they contain colder dust than local galaxies of a similar luminosity. We explore the reasons for the evolving IR emission of similar galaxies over cosmic time using: 1) Local galaxies from GOALS $(L_{\rm IR}=10^{11}-10^{12}\,L_\odot)$; 2) Galaxies at $z\sim0.1-0.5$ from the 5MUSES ($L_{\rm IR}=10^{10}-10^{12}\,L_\odot$); 3) IR luminous galaxies spanning $z=0.5-3$ from GOODS and Spitzer xFLS ($L_{\rm IR}>10^{11}\,L_\odot$). All samples have Spitzer mid-IR spectra, and Herschel and ground-based submillimeter imaging covering the full IR spectral energy distribution, allowing us to robustly measure $L_{\rm IR}^{\rm\scriptscriptstyle SF}$, $T_{\rm dust}$, and $M_{\rm dust}$ for every galaxy. Despite similar infrared luminosities, $z>0.5$ dusty star forming galaxies have a factor of 5 higher dust masses and 5K colder temperatures. The increase in dust mass is linked with an increase in the gas fractions with redshift, and we do not observe a similar increase in stellar mass or star formation efficiency. $L_{160}^{\rm\scriptscriptstyle SF}/L_{70}^{\rm\scriptscriptstyle SF}$, a proxy for $T_{\rm dust}$, is strongly correlated with $L_{\rm IR}^{\rm\scriptscriptstyle SF}/M_{\rm dust}$ independently of redshift. We measure merger classification and galaxy size for a subsample, and there is no obvious correlation between these parameters and $L_{\rm IR}^{\rm \scriptscriptstyle SF}/M_{\rm dust}$ or $L_{160}^{\rm\scriptscriptstyle SF}/L_{70}^{\rm\scriptscriptstyle SF}$. In dusty star forming galaxies, the change in $L_{\rm IR}^{\rm\scriptscriptstyle SF}/M_{\rm dust}$ can fully account for the observed colder dust temperatures, suggesting that any change in the spatial extent of the interstellar medium is a second order effect.

description: Hyper-saline water streams, such as the produced water from the oil industry, cannot be treated via the conventional desalination method, such as reverse osmosis (RO), due to the extreme required pressure to overcome the osmotic pressure. This research investigates the effect of oil fouling and cleaning behaviors when the forward osmosis (FO) process is applied to treat hyper-saline-produced water. Synthetic produced water with total dissolved solids (TDS) concentration of 240 g/l (contained Na, Ca, Mg, Fe, Cl, SO4, and CO3 ions) and oil content of 100 ppm was used as a feed solution. Also, two draw solutions, namely: ammonium bicarbonate (NH4HCO3) and magnesium chloride (MgCl2) of concentrations 6 M and 4.8 M, respectively, were utilized for the FO operation. Results showed that the MgCl2 draw solution provided significantly higher water flux than NH4HCO3 due to MgCl2’s high osmotic pressure and low scaling influence. Furthermore, the individual impact of oil was found to be low on the FO’s water flux. However, a synergistic effect between the oil and inorganic scaling was noticed. SEM technique was used to comprehend the observation and analyze the fouling content. Although the feed was a highly polluted stream, it was found that osmotic backwashing can recover more than 90% of the initial flux.

description: Vacuum cold plasma (VCP), a novel non-thermal processing technology used to modify the physicochemical properties and functionalities of food materials, was applied to whey protein isolate (WPI). The treatment affects the protein chemistry and, as a result, leads to differences in the behavior in solution and at interfaces. To minimize the undesirable effects of high oxidation and to increase the effectiveness of reactive species, the VCP treatment was applied at low pressure using different types of gases (air, combination of argon and air, and sulfur hexafluoride (SF₆)). The treatment led to a decrease in the sulfur content and an increase in the carbonyl content, evidenced by oxidation reactions and enhanced disulfide bond formation, as well as cross-linking of protein molecules. Fluorescence-based indicators suggest that the hydrophobicity of the proteins as well as their aggregation increase after VCP treatment with an argon–air gas mixture; however, it decreases after VCP treatments with air and SF₆. The chemical modifications further lead to changes in the pH of aqueous WPI solutions, as well as the average size and ζ-potential of WPI aggregates. Moreover, the dynamic surface tension, surface dilational elasticity, and the thickness of the WPI adsorption layers at the air/water interface depend on the VCP type. SF₆ plasma treatment leads to a significant decrease in pH and an increase in the ζ-potential, and consequently to a significant increase in the aggregate size. The dynamic surface tension as well as the adsorption rates increase after SF₆VCP treatment, but decrease after air–VCP and argon–air–VCP treatments. The adsorbed WPI aggregates form strong viscoelastic interfacial layers, the thickness of which depends on the type of VCP treatment.

description: This paper proposes a theoretical model of voluntary intermunicipal cooperation and empirically tests its assertions through the French municipalities’ choices of transferring their competences to the intermunicipal level. Using an original threshold models inference procedure, a probit model is estimated on shared competences. Two main results arise. Contrary to the decentralisation theorem prediction, citizens’ preference heterogeneity does not hinder local cooperation, but fiscal potential heterogeneity does. Moreover, a zoo effect is at stake for some competences, for which a significant threshold effect in their transfer probability is identified.

description: In recent decades, Europe has experienced a significant slowdown in productivity, accompanied by rising regional inequalities. At the same time, the fragmentation of work and the rise of non-standard forms of employment have deeply reshaped labour markets. Through the analysis of an extensive database comprising data on regional labour markets and productivity trends, we investigate the relationship between non-standard work and labour productivity dynamics in European regions from 2004 to 2018. The findings highlight that increasing non-standard employment across regions is likely to negatively affect labour productivity growth. Moreover, to some extent, the spread of non-standard jobs, especially of permanent, yet involuntary, part-time positions, might contribute to the widening of regional disparities.

description: The existence of pseudomagnetic helicons is predicted for strained Dirac and Weyl materials. The corresponding collective modes are reminiscent of the usual helicons in metals in strong magnetic fields but can exist even without a magnetic field due to a strain-induced background pseudomagnetic field. The properties of both pseudomagnetic and magnetic helicons are investigated in Weyl matter using the formalism of the consistent chiral kinetic theory. It is argued that the helicon dispersion relations are affected by the electric and chiral chemical potentials, the chiral shift, and the energy separation between the Weyl nodes. The effects of multiple pairs of Weyl nodes are also discussed. A simple setup for experimental detection of pseudomagnetic helicons is proposed.

description: We study the influence of the complex topology of scale-free graphs on the dynamics of anti-coordination games (e.g. snowdrift games). These reference models are characterized by the coexistence (evolutionary stable mixed strategy) of two competing species, say "cooperators" and "defectors", and, in finite systems, by metastability and large-fluctuation-driven fixation. In this work, we use extensive computer simulations and an effective diffusion approximation (in the weak selection limit) to determine under which circumstances, depending on the individual-based update rules, the topology drastically affects the long-time behavior of anti-coordination games. In particular, we compute the variance of the number of cooperators in the metastable state and the mean fixation time when the dynamics is implemented according to the voter model (death-first/birth-second process) and the link dynamics (birth/death or death/birth at random). For the voter update rule, we show that the scale-free topology effectively renormalizes the population size and as a result the statistics of observables depend on the network's degree distribution. In contrast, such a renormalization does not occur with the link dynamics update rule and we recover the same behavior as on complete graphs.

description: Digital archives of memory institutions are typically concerned with the cataloguing of artefacts of artistic, historical, and cultural value. Recently, new forms of citizen participation in cultural heritage have emerged, producing a wealth of material spanning from visitors’ experiential feedback on exhibitions and cultural artefacts to digitally mediated interactions like the ones happening on social media platforms. In this talk, I will touch upon the problems of integrating citizen experiences in cultural heritage archives. I argue for good reasons for institutions to archive people’s responses to cultural objects, and then look at the impact that this has on the data infrastructures. I argue that a knowledge organisation system for “data journeys” can help in disentangling problems that include issues of distribution, authoritativeness, interdependence, privacy, and rights management.
title: L2 motivation in higher education: A qualitative study from Egypt

description: Drawing from mainstream psychology, research in L2 motivation started in 1959 with the work of Gardner and Lambert (1959). Since then, the field witnessed major developments, looking at the language learner’s motivation from different angles: the cognitive, the social psychological, and the temporal. One of the models that looks at the language learner from a more holistic perspective is Zoltan Dörnyei’s L2 Motivational Self System (L2MSS) (2005, 2009a). The model examines motivation through three components: the Ideal L2 Self, the Ought-to Self, and the L2 Learning Experience. Any or all these components can enhance the learner’s L2 motivation. This study explores the factors affecting L2 motivation in university students in Egypt from Dörnyei’s theoretical perspective. It uses qualitative methods within an interpretivist/constructivist approach. 20 first-year university students from one higher education institution participated in the study. All participants responded to a qualitative questionnaire which focused on their motivation for English language learning. Subsequently,12 of them agreed to participate in an interview. Data were analysed using Braun and Clarke’s (2006) Thematic Analysis both deductively and inductively. The findings demonstrate that the participants were motivated by all three components of the L2MSS in different levels. Nevertheless, the dominant motivator was the L2 Learning Experience, with special attention to the role of the instructor. Various elements in the study underpin its significance. First, this study explores L2 motivation using the L2MSS as a model for the first time in a qualitative study in Egypt. Second, the study corroborates recent research exploring the overlap between the Ideal and the Ought-to Selves in the learner’s perspectives. Third, this research not only demonstrates the significance of the L2 Learning Experience as a driver for L2 motivation, since it was the least researched component in the model, but also as a factor that can enhance/inhibit the other two components: the Ideal and the Ought-to Selves. The L2 Learning Experience is the dominant motivator according to the findings of the study, and this is supported by the salient role of the instructor. Furthermore, the study highlights the significant role of emotions in reflecting student motivation or demotivation. The findings may help policy makers, curriculum developers and instructors gain a deeper understanding of the different motivators at play in the perception of their students. This in turn can contribute to the creation and development of a better L2 learning environment for the learners.

description: We use Atacama Large Millimeter/submillimeter Array Band 5 science verification observations of the red supergiant VY CMa to study the polarization of SiO thermal/masers lines and dust continuum at ~1.7 mm wavelength. We analyse both linear and circular polarization and derive the magnetic field strength and structure, assuming the polarization of the lines originates from the Zeeman effect, and that of the dust originates from aligned dust grains. We also discuss other effects that could give rise to the observed polarization. We detect, for the first time, significant polarization (~3%) of the circumstellar dust emission at millimeter wavelengths. The polarization is uniform with an electric vector position angle of $\sim8^\circ$. Varying levels of linear polarization are detected for the J=4-3 28SiO v=0, 1, 2, and 29SiO v=0, 1 lines, with the strongest polarization fraction of ~30% found for the 29SiO v=1 maser. The linear polarization vectors rotate with velocity, consistent with earlier observations. We also find significant (up to ~1%) circular polarization in several lines, consistent with previous measurements. We conclude that the detection is robust against calibration and regular instrumental errors, although we cannot yet fully rule out non-standard instrumental effects. Emission from magnetically aligned grains is the most likely origin of the observed continuum polarization. This implies that the dust is embedded in a magnetic field >13 mG. The maser line polarization traces the magnetic field structure. The magnetic field in the gas and dust is consistent with an approximately toroidal field configuration, but only higher angular resolution observations will be able to reveal more detailed field structure. If the circular polarization is due to Zeeman splitting, it indicates a magnetic field strength of ~1-3 Gauss, consistent with previous maser observations.

description: Theories of smart urbanism have overlooked the influence of contextual factors on the conception, planning and implementation of digital transformation practices across regions. To articulate this critique, we focus on African cities and draw on a diverse range of urban and regional scholarship. We present the core assumptions advanced in the mainstream literature on smart urbanism and prove their inability to fit the organisation of African urban contexts. Three main research questions emerge from this critical examination and offer new perspectives for expanding knowledge on how smart urbanism challenges recombine with place-based governance approaches, not only in Africa, but globally.
title: Deep tissue in vivo quantitative optical biopsy

Subjects: subject: biomedical optics, vascular oximetry, multispectral imaging, microendoscopy, hypoxia, inflammation, rheumatoid arthritis, multiple sclerosis.

description: The study of vascular oxygen saturation has important implications in a range of diseases with which inflammation and hypoxia are associated. This thesis details advancements in multispectral imaging systems for in vivo optical biopsy, relating to new applications primarily for the localised measurement of blood oxygen saturation in vivo, and also fluorescence cellular imaging. A calibration-free oximetry technique, based on previous work in retinal oximetry, was developed for the purposes of microvascular oximetry analysis in deep tissue. A novel multispectral microscope was developed for imaging of the microvasculature, with annular back-illumination providing glint-free images and simplification of the optical oximetry model. This system was successfully employed for proof-of-concept oximetry in the mouse tendon, resulting in the first localised measurements of vascular hypoxia associated with acute inflammation. The tendon is of interest as it is affected by auto-immune inflammatory diseases such as rheumatoid arthritis. A further application of the oximetry algorithm to inflammation in the spinal cord of rats is described in this thesis, in which hypoxia associated with a rat model for multiple sclerosis was successfully quantified. The latter part of the thesis describes advancements made towards incorporating microendoscopic probes to the imaging system, extending the calibration-free oximetry technique to applications where minimally-invasive imaging is required. Preliminary ex vivo validation experiments in the mouse tendon are described. Finally, the minimally-invasive system was modified for multispectral fluorescence microscopy, and a novel technique for localised delivery of fluorophore-conjugated antibodies is described. Localised interventions and observations of immunological events is of interest to biologists as a greater understanding of immune-related disease can potentially be gained. Preliminary ex vivo experiments observing the binding of antibodies to T cells in the lymph node are described.

description: We improve the Monte-Carlo based QCD sum rules by introducing the rigorous Hölder-inequality-determined sum rule window and a Breit-Wigner type parametrization for the phenomenological spectral function. In this improved sum rule analysis methodology, the sum rule analysis window can be determined without any assumptions on OPE convergence or the QCD continuum.Therefore an unbiased prediction can be obtained for the phenomenological parameters (the hadronic mass and width etc.). We test the new approach in the $ρ$ meson channel with re-examination and inclusion of $α_s$ corrections to dimension-4 condensates in the OPE. We obtain results highly consistent with experimental values. We also discuss the possible extension of this method to some other channels.

title: Investigating the role of CBFβ in breast cancer
Creators: name: Khan, Adiba Sanjana

description: Despite the advances in therapy and improved patient mortality rates, breast cancer remains one of the leading causes of cancer associated deaths in women across the globe. The transcription co-factor, Core Binding Factor-beta (CBFβ), which is the binding partner for the RUNX family of proteins, is a recurrently mutated gene in breast cancer. Up to 14% of breast cancer patients harbour genetic alterations in this gene, across both oestrogen receptor (ER) positive and ER negative subtypes of the disease. The majority of these alterations have been found to be loss of function mutations and homozygous deletions in CBFβ, indicating a potential tumour suppressive role of this protein. The functionality of Cbfβ loss in mammary tumorigenesis was studied here using genetically engineered mouse models of a luminal B breast cancer model (MMTV-PyMT) and a Wnt/β-catenin driven mammary cancer mouse model. Consistent with loss of function mutations/deletions in patient cohorts, a tumour suppressor role of Cbfβ was confirmed for the first time in vivo where homozygous loss of Cbfβ in mammary epithelial cells dramatically accelerated Wnt/β-catenin driven tumour initiation and progression. Transcriptomic analysis of tumour samples deficient in Cbfβ revealed significant upregulation of genes encoding various activators of the Wnt/β-catenin pathway and downregulation of its inhibitors indicating marked augmentation of this signalling cascade. Genes involved in activation of other oncogenic pathways, including the Notch pathway, also appeared enriched in samples where Cbfβ was absent. Strikingly, alterations in the immune regulatory pathways of the Cbfβ-deficient tumour microenvironment were particularly evident in the RNAseq analysis and Cbfβ deficient pre-neoplastic glands also displayed an increased infiltration of immune cell infiltrates. Combined deletion of CBFβ binding partners, Runx1 and Runx2 showed a similar acceleration of Wnt/β-catenin driven tumorigenesis although differences in the transcriptomic and immune landscape between Runx1-Runx2 deficient and Cbfβ deficient tumours suggested that the mechanisms of action may not be entirely synonymous. Interestingly loss of Cbfβ from PyMT tumour cell lines showed that the tumour suppressor effect of CBFβ is not universal. This study provides the first in vivo evidence that Cbfβ loss might be associated with promotion of mammary tumorigenesis through hyperactivation of Wnt signalling and with an induction of a pro-tumorigenic immune response.

description: We assess the economic resilience of British subregions before, during and after the 2008 financial crisis. We apply our economic resilience scorecard to employment, output and productivity to assess the resilience dimensions of resistance, recovery and renewal. Our resulting scorecard ranks the South Eastern subregions and the Bristol/Bath region as having the highest economic resilience following the 2008 crisis, with Northumberland and Tyne and Wear, and East Yorkshire and Northern Lincolnshire having the lowest. Further policy measures are discussed to build regional resilience in recovery from multiple crisis.
