description: In the cyanobacterium Thermosynechococcus elongatus BP-1, living in hot springs, the light environment directly regulates expression of genes that encode key components of the photosynthetic multi-subunit protein-pigment complex photosystem II (PSII). Light is not only essential as an energy source to power photosynthesis, but leads to formation of aggressive radicals which induce severe damage of protein subunits and organic cofactors. Photosynthetic organisms develop several protection mechanisms against this photo-damage, such as the differential expression of genes coding for the reaction center subunit D1 in PSII. Testing the expression of the three different genes (psbAI, psbAII, psbAIII) coding for D1 in T. elongatus under culture conditions used for preparing the material used in crystallization of PSII showed that under these conditions only subunit PsbA1 is present. However, exposure to high-light intensity induced partial replacement of PsbA1 with PsbA3. Modeling of the variant amino acids of the three different D1 copies in the 3.0 Å resolution crystal structure of PSII revealed that most of them are in the direct vicinity to redox-active cofactors of the electron transfer chain. Possible structural and mechanistic consequences for electron transfer are discussed.

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.
Effects of Phase Change Materials on heat flows through double skin facades

Publisher: name: Journal of Facade Design and Engineering
Year: 2021

description: The potential of exemplary organic and inorganic Phase Change Materials (PCMs) as façade integrated storage is tested. The impact of two PCMs on heat flows is assessed in comparison with water and concrete. The simulation-study employs a transient Modelica simulation model of a test cell featuring the Solar Energy Balanced Façade (SEBF). It is shown that, when compared to water, PCMs of identical volume change the seasonal energy balance in winter and summer by only ± 4%. Other than water, the PCMs maintain this effect even if the storage volume decreases. Due to spatial constraints, this can support the integration of thermal storage in façade design considerably. Preliminary results indicate that designing thermal storage in façades with PCMs must not only consider the latent heat storage capacity, but also take into account the combined effects of latent heat capacity, melting point, conductivity, and dead load. The application of PCMs promises to foster the integration of the technology of SEBF into façades, but the necessary deliberate selection of, and design with, PCMs requires further research.

Diet and Health in the North Carolina Piedmont

description: This study uses the dental and cranial skeletal remains of populations interred in the North Carolina Piedmont, including those from the archaeological sites of Town Creek, Forbush Creek, Early Upper Saratown (Hairston), Wall, Fredricks, and Upper Saratown, to present the frequencies of dental and cranial pathologies in the context of the cultural and biological setting of the North Carolina piedmont in order to assess how agriculture and European contact influenced nutrition and overall health. The collection samples range from A.D. 700-1710, a period that encompasses a series of dietary transformations that include the increased incorporation of maize into the diet, and after the arrival of Europeans into the area, a change in diet associated with increased mobility.
The study’s purpose was to look at what dental and skeletal cranial markers can tell us about diet and overall health. Data were collected by observing the presence and number of carious lesions, alveolar infection, premortem tooth loss, and dental calculus. I also recorded frequencies of porotic hyperostosis, cribra orbitalia and scurvy as additional evidence of diet and health deficiencies. The results of this study suggest a decline in health during a period of time when agriculture was the most dominant part of a subsistence economy, the middle period of my sample that contains samples from A.D. 1450 to 1620, and a reduction in nutritional strain for populations with a more mixed economy, especially the late period of my sample (1670-1710).

Resilient Timber Construction in the Era of Climate Change: Lessons from the Mountain Pine Beetle
Creators: name: Burrows, John H.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2014

description: The demands placed on the environment to supply raw-materials for future construction require changing the current paradigm away from carbon intensive materials. Replacing steel and concrete with wood as a construction material has been one suggestion to help make this transition because of the avoided carbon emissions from wood construction. However, this emphasis on wood construction comes at a time when the forests across North America are increasingly vulnerable to the impacts of climate change. Consequently, the timber industry’s ability to use wood killed in climate-related disturbances has become increasingly important both economically and environmentally. Beginning with the example of the mountain pine beetle, this paper discusses the challenges and opportunities of using salvaged wood as a construction material. It demonstrates how the use of salvaged wood in construction can result in up to 24.8% more avoided carbon emissions than the use of normal wood. Using three examples of newly constructed wood buildings in Europe, the value of these avoided emissions is estimated as a percentage of the building cost and per cubic meter of wood used in construction. Results indicate that depending on the price of carbon, the values used to estimate avoided emissions from wood substitution, and the assumptions regarding the alternative uses for salvaged wood, that the value of avoided emissions from using salvaged wood could be as high as 2.3% of the building cost. If this value was made accessible to developers, it could be used as a financial incentive to increase the demand for wood products and encourage greater utilization of salvageable wood as a green building material.

Physicians’ Experiences of Touch, a Hermeneutic Reflection
Creators: name: Kelly, Dr. Martina
Publisher: name: Journal of Applied Hermeneutics
Year: 2023

description: Touch is central to clinical practice but can be a “touchy subject” in medical education, simultaneously associated with care, and risk. In the clinical literature, touch is typically categorised as communicative or procedural, with an emphasis on touch as behavioural. Philosophically, touch is also a subject of consideration, yet this literature remains relatively unfamiliar to clinicians. In this essay, I reflect on touch in healthcare and medical education, as explored in my PhD studies, drawing on the work of hermeneutic philosophers, particularly Merleau-Ponty. Interpreting touch, I propose, is inherently hermeneutic, offering many possibilities to deepen our understanding of human interaction and clinical practice. Touch embodies the clinician-patient relationship as a holistic encounter. In high intensity interactions, touch orientates expression of empathy “beyond words". I present the significance of hermeneutics for clinical education, to richly re-imagine, and challenge, the concept of patient-centredness.

description: Turbulent fluid has often been conceptualized as a transient thermodynamic phase. Here, a finite-time thermodynamics (FTT) formalism is proposed to compute mean flow and fluctuation levels of unsteady incompressible flows. The proposed formalism builds upon the Galerkin model framework, which simplifies a continuum 3D fluid motion into a finite-dimensional phase-space dynamics and, subsequently, into a thermodynamics energy problem. The Galerkin model consists of a velocity field expansion in terms of flow configuration dependent modes and of a dynamical system describing the temporal evolution of the mode coefficients. Each mode is treated as one thermodynamic degree of freedom, characterized by an energy level. The dynamical system approaches local thermal equilibrium (LTE) where each mode has the same energy if it is governed only by internal (triadic) mode interactions. However, in the generic case of unsteady flows, the full system approaches only partial LTE with unequal energy levels due to strongly mode-dependent external interactions. The FTT model is first illustrated by a traveling wave governed by a 1D Burgers equation. It is then applied to two flow benchmarks: the relatively simple laminar vortex shedding, which is dominated by two eigenmodes, and the homogeneous shear turbulence, which has been modeled with 1459 modes.

An Extra Electrostatic Energy in Semiconductors and its Impact in Nanostructures

description: This work revisits the classical concept of electric energy and suggests that the common definition is likely to generate large errors when dealing with nanostructures. For instance, deriving the electrostatic energy in semiconductors using the traditional formula fails at giving the correct electrostatic force between capacitor plates and reveals the existence of an extra contribution to the standard electrostatic energy. This additional energy is found to proceed from the generation of space charge regions which are predicted when combining electrostatics laws with semiconductor statistics, such as for accumulation and inversion layers. On the contrary, no such energy exists when relying on electrostatics only, as for instance when adopting the so-called full depletion approximation. The same holds for charged or neutral insulators that are still consistent with the customary definition, but which are in fact singular cases. In semiconductors, this additional free energy can largely exceed the energy gained by the dipoles, thus becoming the dominant term. Consequently, erroneous electrostatic forces in nanostructure systems such as for MEMS and NEMS as well as incorrect energy calculations are expected using the standard definition. This unexpected result clearly asks for a generalization of electrostatic energy in matter in order to reconcile basic concepts and to prevent flawed force evaluation in nanostructures with electrical charges.

Experiment 2. Selective visual attention to faces: Is emotion a special feature?
Creators: name: Schindler, Sebastian
Publisher: name: Open Science Framework
Year: 2022

description: This is Experiment 2 of the project (osf.io/f3kn4) on the interaction of attention and facial features (age or emotion). Based on our first experiment we updated our prediction on the findings: Similar to the preregistration of Experiment 1, we expect an enlarged N170 for happy and old faces, an enlarged EPN for happy and young faces. Further, we expected an interaction of attention and emotion in the LPP but no interaction of attention and age. We found this pattern, however, contrary to our expectation, the LPP was not selectively enlarged for happy faces but rather for neutral faces. Moreover, we also observed an P1 effect for old faces. This updated pattern is expected in Experiment 2, by changing the attention manipulation from an explicit (button response) to a silent counting condition.

In this work, we propose a way of stabilizing the ring dark soliton via a radial Gaussian external potential. We investigate the existence and stability of the ring dark soliton upon variations of the chemical potential and also of the strength of the radial potential. Numerical results show that the ring dark soliton can be stabilized in a suitable interval of external potential strengths and chemical potentials. We also explore different proposed particle pictures considering the ring as a moving particle and find, where appropriate, results in very good qualitative and also reasonable quantitative agreement with the numerical findings.

description: ${\textbf{Background:}}$ Atomic nuclei often exhibit collective rotational-like behavior in highly excited states, well above the particle emission threshold. What determines the existence of collective motion in the continuum region, is not fully understood. ${\textbf{Purpose:}}$ In this work, by studying the collective rotation of the positive-parity deformed configurations of the one-neutron halo nucleus $^{11}$Be, we assess different mechanisms that stabilize collective behavior beyond the limits of particle stability. ${\textbf{Method:}}$ To solve a particle-plus-core problem, we employ a non-adiabatic coupled-channel formalism and the Berggren single-particle ensemble, which explicitly contains bound states, narrow resonances, and the scattering continuum. We study the valence-neutron density in the intrinsic rotor frame to assess the validity of the adiabatic approach as the excitation energy increases. ${\textbf{Results:}}$ We demonstrate that collective rotation of the ground band of $^{11}$Be is stabilized by (i) the fact that the $\ell=0$ one-neutron decay channel is closed, and (ii) the angular momentum alignment, which increases the parentage of high-$\ell$ components at high spins; both effects act in concert to decrease decay widths of ground-state band members. This is not the case for higher-lying states of $^{11}$Be, where the $\ell=0$ neutron-decay channel is open and often dominates. ${\textbf{Conclusion:}}$ We demonstrate that long-lived collective states can exist at high excitation energy in weakly bound neutron drip-line nuclei such as $^{11}$Be.

This is done under the assumption that the statistical properties of the data can be modelled by a multivariate Gaussian distribution. We use this to show how one can optimise an experiment to find evidence for a fixed function over perturbations about this function. We apply this formalism to an illustrative problem of measuring perturbations in the dark energy equation of state about a cosmological constant.

description: The MEarth Project is a photometric survey systematically searching the smallest stars nearest to the Sun for transiting rocky planets. Since 2008, MEarth has taken approximately two million images of 1844 stars suspected to be mid-to-late M dwarfs. We have augmented this survey by taking nightly exposures of photometric standard stars and have utilized this data to photometrically calibrate the $MEarth$ system, identify photometric nights, and obtain an optical magnitude with $1.5\%$ precision for each M dwarf system. Each optical magnitude is an average over many years of data, and therefore should be largely immune to stellar variability and flaring. We combine this with trigonometric distance measurements, spectroscopic metallicity measurements, and 2MASS infrared magnitude measurements in order to derive a color-magnitude-metallicity relation across the mid-to-late M dwarf spectral sequence that can reproduce spectroscopic metallicity determinations to a precision of 0.1 dex. We release optical magnitudes and metallicity estimates for 1567 M dwarfs, many of which did not have an accurate determination of either prior to this work. For an additional 277 stars without a trigonometric parallax, we provide an estimate of the distance assuming solar neighborhood metallicity. We find that the median metallicity for a volume limited sample of stars within 20 parsecs of the Sun is [Fe/H] = $-0.03 \pm 0.008$, and that 29 / 565 of these stars have a metallicity of [Fe/H] = $-0.5$ or lower, similar to the low-metallicity distribution of nearby G-dwarfs. When combined with the results of ongoing and future planet surveys targeting these objects, the metallicity estimates presented here will be important in assessing the significance of any putative planet-metallicity correlation.

Effect of SHH interruption on cerebellar development
Creators: name: Rapp, Carolyn
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2018

description: During development, disruptions in sonic hedgehog (SHH) signaling can lead to medulloblastoma, the most common malignant pediatric brain tumor. Medulloblastoma tumor cells arise from cerebellar granule neural progenitors (CGNPs), which rely on SHH signaling to proliferate. Inhibiting the SHH pathway is a focus of research in treatment of medulloblastoma. It is known that SHH is closely linked with the cell cycle, but it was not known how SHH pathway inhibition affects gene expression in CGNPs. To simulate SHH-deprivation, we performed microarray analysis using RNA from wild-type progenitor cells cultured in the presence or absence of SHH. We found that in absence of SHH, there is significant suppression of genes in all phases of the cell cycle, confirming that CGNPs depend on SHH to proliferate. To investigate the effects of indirect SHH inhibition on gene expression, we used vismodegib, an FDA-approved inhibitor of the SHH ligand receptor SMOOTHENED (SMO). Wild-type mice were injected with either vismodegib or a vehicle control and we collected RNA from CGNPs. We performed RNA-sequencing analysis to compare expression levels of cell cycle markers, differentiation markers, and SHH markers. Our preliminary data suggests that vismodegib promotes differentiation and suppresses proliferation. We will use differential gene expression analysis to identify genes of interest and validate our findings through immunohistochemistry. These biological markers could be used to further medulloblastoma treatment research and, more specifically, to help identify cells that are unaffected by vismodegib and cause recurrence in medulloblastoma patients.

description: This guide was written by Dr Smita Odedra (Senior Lecturer in Physical Chemistry, School of Chemistry, University of Glasgow), who created the Twelve Scents of Christmas chemistry outreach activity.Twelve Scents of Christmas is a festive-themed Chemistry outreach activity that I created in 2018. This guide is intended to help users recreate and run this chemistry outreach activity. It can be tailored to your own learning outcomes based on your target audience.Twelve Scents of Christmas is an interactive tabletop activity which has proved successful at engaging audiences of all ages. The University of Glasgow’s Chemistry Outreach Group has used it at a variety of events including community Christmas fayres, school visits, science museums, and undergraduate socials. The activity is fun, easy to run, and doesn’t create a mess. Once the activity materials have been created, the kit is easy to transport and set up, and lends itself well for reuse without further investment in consumables.Resource DOI: 10.25416/NTR.24204567The project was funded by the Royal Society of Chemistry (Glasgow & West of Scotland Local Section) – September 2018Download the printable version of the Guide or view the more festive version at

description: For cylindrical differentially rotating plasmas, we study large-scale magnetic field generation from finite amplitude non-axisymmetric perturbations by comparing numerical simulations with quasi-linear analytic theory. When initiated with a vertical magnetic field of either zero or finite net flux, our global cylindrical simulations exhibit the magnetorotational instability (MRI) and large scale dynamo growth of radially alternating mean fields, averaged over height and azimuth. This dynamo growth is explained by our analytic calculations of a non-axisymmetric fluctuation-induced EMF that is sustained by azimuthal shear of the fluctuating fields. The standard "Omega effect" (shear of the mean field by differential rotation) is unimportant. For the MRI case, we express the large-scale dynamo field as a function of differential rotation. The resulting radially alternating large-scale fields may have implications for angular momentum transport in disks and corona. To connect with previous work on large scale dynamos with local linear shear and identify the minimum conditions needed for large scale field growth, we also solve our equations in local Cartesian coordinates. We find that large scale dynamo growth in a linear shear flow without rotation can be sustained by shear plus non-axisymmetric fluctuations -- even if not helical, a seemingly previously unidentified distinction. The linear shear flow dynamo emerges as a more restricted version of our more general new global cylindrical calculations.

Extended Jackiw-Pi Model and Its Supersymmetrization

Subjects: subject: High Energy Physics - Theory (hep-th)

description: We present an extended version of the so-called Jackiw-Pi (JP) model in three dimensions, and perform its supersymmetrization. Our field content has three multiplets: (i) Yang-Mills vector multiplet $(A_μ^I, λ^I)$, (ii) Parity-odd extra vector multiplet $(B_μ^I, χ^I)$, and (iii) Scalar multiplet $(C^I, ρ^I, f^I)$. The bosonic fields in these multiplets are the same as the original JP-model, except for the auxiliary field $~f^I$ which is new, while the fermions $λ^I, χ^I$ and $ρ^I$ are their super-partners. The basic difference from the original JP-model is the presence of the kinetic term for $C^I$ with its modified field-strength $H_μ^I \equiv D_μC^I + m B_μ^I$. The inclusion of the $C^I$-kinetic term is to comply with the recently-developed tensor hierarchy formulation for supersymmetrization.

The Acquisition of German Verb-Selected Prepositions and Derivational Prefixes in Adult Native English Speakers
Creators: name: Hersh, Meghan
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2015

description: Second Language Acquisition (SLA) is a subfield of linguistics interested in researching how
persons acquire second languages (L2) and further. It is a common view that adult learners (adult
here meaning post-pubescent) are unable to acquire a native-level command in an L2. As this is a
common end goal for second language learners, much of the research in the field looks at what
stands in the way of this goal, and how it may be achieved. Most learners achieve, instead of
native proficiency, a form of 'interlanguage' (Section 1.1). How advanced this interlanguage is
varies between people.
In this study, I focus on the acquisition of two features of the German language: verbselected
prepositions and verbal prefixes, which are discussed in more detail in Sections 1.5. The
rate of acquisition of these and other language features are dependent on various factors, which
may either help or hinder acquisition. These factors include influence from the mother tongue
(L1), the frequency at which learners are in contact with a feature, and how difficult the item is.
These are discussed in Sections 1.1 through 1.4.

Push button reproduction attempt of a research claim from Leder et al. (2020)
Creators: name: Somo, Angela
Publisher: name: Open Science Framework
Year: 2022
Subjects: subject: Social and Behavioral Sciences

description: We selected the claim that individuals seek self-protective measures first and foremost with public protection being only a secondary motive. This reflects the following statement from the paper’s abstract: “Although our sample (German general public, N = 419, age = 38.07 (15.67) years, female = 71.1 % (diverse = 0.5%), students = 34.37%) consisted mostly of prosocially oriented individuals, we found that, above all, participants used protective measures that protected themselves”. The claim was tested by using the library glmmTMB (Brooks et al., 2017) for generalized linear mixed model analysis and psych (Revelle, 2019) for psychometric tools, where SVO (social value orientation), self-protection value, public protection value, and their interactions predicted use of protective behaviors against COVID-19.This resulted in finding that people use protective measures that foremost protect themselves (from Table 2: self-protection value estimate = 0.75, p = 0.0053).

Phenyl-modified phosphosilicate gels for proton conductivity
Creators: name: Joseph, Lorne S.
Publisher: name: No Publisher Supplied

description: Proton (H+) transport in membranes and solid electrolytes leads to their potential use in fuel cells and chemical sensors. Phenyl and zirconia modified phosphosilicate gels were successfully synthesized and demonstrate interesting properties that suggest that these materials have future use as proton conductors. The amount of substitution and the amount of zirconia have been varied. Conductivity measurements using a Four-Point Probe were used to determine the effects of the substitutions on proton conduction in the gel samples. The highest value of conductivity was 1.48E-05 S/m for the sample with 5 wt.% PhTES and 5 wt.% TPZr (5PPS-5Z). The molecular structure of the gels was investigated using FTIR and Raman spectroscopy, to identify hydroxyls and phenyl groups, and the presence of bridging oxygen bonds in the samples. The FTIR transmission spectra explain the nature of the functional groups that are present in the three samples and the Raman spectra display the characteristic peaks for a silica and phosphate network. The samples were also subjected to nanoindentation, it was observed that samples with phenyl substitutions showed some plasticity, while samples without phenyl substitution were brittle. The results of the BET analysis indicate that all three samples have minimal surface area that is accessible to nitrogen. The pore volume is also very low, indicating that the compositions with and without phenyl substitutions have almost no measurable pore volume. The water adsorption studies for samples at 99 % RH for about one hour show a steady increase in the samples mass. The samples, despite being phenyl modified are still able to take in water. The substitution of a phenyl group on the silica precursor as well as the addition of zirconium (IV) ions in the formulation of phosphosilicate gels for proton conduction has interesting effects on the mechanical, structural, thermal and transport properties.
A criterion for many-body localization-delocalization phase transition

description: We propose a new approach to probing ergodicity and its breakdown in quantum many-body systems based on their response to a local perturbation. We study the distribution of matrix elements of a local operator between the system's eigenstates, finding a qualitatively different behaviour in the many-body localized (MBL) and ergodic phases. To characterize how strongly a local perturbation modifies the eigenstates, we introduce the parameter ${\cal G}(L)=\langle \ln (V_{nm}/δ) \rangle$, which represents a disorder-averaged ratio of a typical matrix element of a local operator $V$ to the energy level spacing, $δ$; this parameter is reminiscent of the Thouless conductance in the single-particle localization. We show that the parameter ${\cal G}(L)$ decreases with system size $L$ in the MBL phase, and grows in the ergodic phase. We surmise that the delocalization transition occurs when ${\cal G}(L)$ is independent of system size, ${\cal G}(L)={\cal G}_c\sim 1$. We illustrate our approach by studying the many-body localization transition and resolving the many-body mobility edge in a disordered 1D XXZ spin-1/2 chain using exact diagonalization and time-evolving block decimation methods. Our criterion for the MBL transition gives insights into microscopic details of transition. Its direct physical consequences, in particular logarithmically slow transport at the transition, and extensive entanglement entropy of the eigenstates, are consistent with recent renormalization group predictions.
