description: Many-body localized (MBL) systems are characterized by the absence of transport and thermalization, and therefore cannot be described by conventional statistical mechanics. In this paper, using analytic arguments and numerical simulations, we study the behaviour of local observables in an isolated MBL system following a quantum quench. For the case of a global quench, we find that the local observables reach stationary, highly non-thermal values at long times as a result of slow dephasing characteristic of the MBL phase. These stationary values retain the local memory of the initial state due to the existence of local integrals of motion in the MBL phase. The temporal fluctuations around stationary values exhibit universal power-law decay in time, with an exponent set by the localization length and the diagonal entropy of the initial state. Such a power-law decay holds for any local observable and is related to the logarithmic in time growth of entanglement in the MBL phase. This behaviour distinguishes the MBL phase from both the Anderson insulator (where no stationary state is reached), and from the ergodic phase (where relaxation is expected to be exponential). For the case of a local quench, we also find a power-law approach of local observables to their stationary values when the system is prepared in a mixed state. Quench protocols considered in this paper can be naturally implemented in systems of ultra cold atoms in disordered optical lattices, and the behaviour of local observables provides a direct experimental signature of many-body localization.

description: We investigate the retrieval of spatially resolved atomic displacements via the phases of the direct(real)-space image reconstructed from the strained crystal's coherent x-ray diffraction pattern. We demonstrate that limiting the spatial variation of the first and second order spatial displacement derivatives improves convergence of the iterative phase retrieval algorithm for displacements reconstructions to the true solution. Our approach is exploited to retrieve the displacement in a periodic array of silicon lines isolated by silicon dioxide filled trenches.

Localizations with noncompact transverse spaces and covert symmetry breaking in supergravity
Creators: name: Erickson, Christopher W.
Publisher: name: Imperial College London
Year: 2022

description: The focus of my doctoral work has been answering the question: Can lower-dimensional effective gravitational theories be found in a higher-dimensional theory with a non-compact transverse space? To answer this question this thesis is divided into two parts. First, I explore supergravity solutions on warped product manifolds and argue that they correspond to solutions of a modified Laplacian. I pay special attention to Type III † solutions, or solutions characterized by the presence of non-constant transverse zero modes, and emphasize that these are the only higher dimensional solutions corresponding to localized sources that yield effectively lower-dimensional physics when the transverse space has infinite volume. Second, I derive the lower dimensional effective field theory about such backgrounds. I discover that these effective field theories have covert symmetry breaking, spontaneous breaking of gauge symmetry which only appears at quartic order. I show this explicitly for D = d + 1 scalar electrodynamics with any boundary condition that corresponds to a non-constant transverse zero mode. The mathematical prerequisite for both of these conclusions is Sturm–Liouville theory with precise manipulations of Green’s formula. To support this I derive the fundamental conclusions of Sturm–Liouville theory for a restricted class of operator, that is the Laplacian, which relaxes some requirements for permissible boundary conditions of Sturm–Liouville theory. The answer to my focal question is: Yes; however, the lower-dimensional theory has novel corrections which were previously unexplored, and further research is indicated.

description: Mammalian SWI/SNF chromatin-remodeling complexes utilize either BRG1 or Brm as alternative catalytic subunits to alter the position of nucleosomes and regulate gene expression. Genetic studies have demonstrated that SWI/SNF complexes are required during cardiac development and also protect against cardiovascular disease and cancer. However, Brm constitutive null mutants do not exhibit a cardiomyocyte phenotype and inducible Brg1 conditional mutations in cardiomyocyte do not demonstrate differences until stressed with transverse aortic constriction, where they exhibit a reduction in cardiac hypertrophy. We recently demonstrated the overlapping functions of Brm and Brg1 in vascular endothelial cells and sought here to test if this overlapping function occurred in cardiomyocytes. Brg1/Brm double mutants died within 21 days of severe cardiac dysfunction associated with glycogen accumulation and mitochondrial defects based on histological and ultrastructural analyses. To determine the underlying defects, we performed nontargeted metabolomics analysis of cardiac tissue by GC/MS from a line of Brg1/Brm double-mutant mice, which lack both Brg1 and Brm in cardiomyocytes in an inducible manner, and two groups of controls. Metabolites contributing most significantly to the differences between Brg1/Brm double-mutant and control-group hearts were then determined using the variable importance in projection analysis. Increased cardiac linoleic acid and oleic acid suggest alterations in fatty acid utilization or intake are perturbed in Brg1/Brm double mutants. Conversely, decreased glucose-6-phosphate, fructose-6-phosphate, and myoinositol suggest that glycolysis and glycogen formation are impaired. These novel metabolomics findings provide insight into SWI/SNF-regulated metabolic pathways and will guide mechanistic studies evaluating the role of SWI/SNF complexes in homeostasis and cardiovascular disease prevention.

description: Ο σύγχρονος κόσμος χαρακτηρίζεται από τον κεντρικό ρόλο που παίζει η οικονομία τόσο σε εθνικό όσο και σε διεθνές επίπεδο. Η ισχύς της εθνικής οικονομίας καθορίζει τη θέση του κράτους στο διεθνές στερέωμα, το οποίο επίσης διαμορφώνεται από τον οικονομικό ανταγωνισμό και την, κατά κανόνα παροδική, οικονομική συνεργασία των κρατών. Παράλληλα, ένας άλλος τομέας που έχει βασική σημασία στο πλαίσιο των διεθνών σχέσεων, είναι η κατασκοπία που χρησιμοποιείται από τα κράτη για τη βελτίωση της θέσης τους. Η παρούσα εργασία έχει ως αντικείμενο το σημείο τομής μεταξύ της οικονομίας και της κατασκοπίας, οπότε ξεκινάει με την ανάλυση της οικονομίας, μετά της κατασκοπίας και τελικά της οικονομικής κατασκοπίας. Η μελέτη της σημασίας της οικονομίας στην ανθρώπινη ιστορία και στις μέρες μας ακολουθεί τα διδάγματα της θεωρίας των διεθνών σχέσεων και την εξετάζει από τρεις βασικές σκοπιές: ως συστατικό της κρατικής ισχύος, ως κομμάτι ιδεολογίας και γενικά ως μέρος της ιστορίας. Η κατασκοπία είναι η αποστολή των μυστικών υπηρεσιών, οι οποίες συλλέγουν πληροφορίες με θεμιτά ή με δόλια μέσα και προστατεύουν τις ευαίσθητες πληροφορίες του κράτους από την υποκλοπή. Στο μεταίχμιο των δύο, η οικονομική κατασκοπία είναι η αξιοποίηση του χρήσιμου εργαλείου της κατασκοπίας στον κρίσιμο τομέα της οικονομίας. Χωρίζεται σε μακροοικονομική και μικροοικονομική και υπάρχουν πολλές μέθοδοι διεξαγωγής της. Στην πράξη, η εφαρμογή της οικονομικής κατασκοπίας είναι αρκετά συχνή, ιδίως για μεγάλα κράτη όπως οι ΗΠΑ και η Κίνα. Οι υπηρεσίες πληροφοριών τους παίρνουν μέρος στην ευρύτερη κόντρα μεταξύ τους, με τη σταδιακή κλιμάκωση του ανταγωνισμού.

description: This report summarizes the body of knowledge for doctoral programs in each of the major disciplines and highlights their commonalities and differences focusing on transferable and soft skills important for the further career of graduates in academia, in private (commercial/business) sector, nonprofit organizations and public institutions. The main goal is an effective integration of transferable skills in PhD programmes and the high quality of the offered courses based on a modular concept. To create this report, we have examined curriculum guidelines for doctoral education and have referred to the transferable and soft skills and other supporting information as necessary. Furthermore, we used the experience obtained during the development and pilot implementation of three transferable skills courses based on the concept of three consecutive modules (online, group work, and non-academic experience). College-level faculty and administrators of doctoral schools and/or doctoral study programs are the audiences for this report.

description: Cognitive function depends on an adaptive balance between flexible dynamics and integrative processes in distributed cortical networks. Patterns of zero-lag synchrony likely underpin numerous perceptual and cognitive functions. Synchronization fulfils integration by reducing entropy, whilst adaptive function mandates that a broad variety of stable states be readily accessible. Here, we elucidate two complementary influences on patterns of zero-lag synchrony that derive from basic properties of brain networks. First, mutually coupled pairs of neuronal subsystems -- resonance pairs -- promote stable zero-lag synchrony amongst the small motifs in which they are embedded, and whose effects can propagate along connected chains. Second, frustrated closed-loop motifs disrupt synchronous dynamics, enabling metastable configurations of zero-lag synchrony to coexist. We document these two complementary influences in small motifs and illustrate how these effects underpin stable versus metastable phase-synchronization patterns in prototypical modular networks and in large-scale cortical networks of the macaque (CoCoMac). We find that the variability of synchronization patterns depends on the inter-node time delay, increases with the network size, and is maximized for intermediate coupling strengths. We hypothesize that the dialectic influences of resonance versus frustration may form a dynamic substrate for flexible neuronal integration, an essential platform across diverse cognitive processes.

description: Chronic ingestion of water containing inorganic arsenic (iAs) has been linked to a variety of adverse health effects, including cancer, hypertension and diabetes. Current evidence suggests that the toxic methylated trivalent metabolites of iAs, methylarsonous acid (MAs) and dimethylarsinous acid (DMAsIII) play a key role in the etiology of these diseases. Both MAs and DMAsIII have been detected in urine of subjects exposed to iAs. However, the rapid oxidation of DMAsIII and, to a lesser extent, MAsIII in oxygen-rich environments leads to difficulties in the analysis of these metabolites in samples of urine collected in population studies. Results of our previous work indicate that MAsIII and DMAsIII are relatively stable in a reducing cellular environment and can be quantified in cells and tissues. In the present study, we used the oxidation state-specific hydride generation-cryotrapping-atomic absorption spectroscopy (HG-CT-AAS) to examine the presence and stability of these trivalent metabolites in the liver of mice and in UROtsa/F35 cells exposed to iAs. Tri- and pentavalent metabolites of iAs were analyzed directly (without chemical extraction or digestion). Liver homogenates prepared in cold deionized water and cell culture medium and lysates were stored at either 0 °C or −80 °C for up to 22 days. Both MAsIII and DMAsIII were stable in homogenates stored at −80 °C. In contrast, DMAsIII in homogenates stored at 0 °C began to oxidize to its pentavalent counterpart after 1 day; MAsIII remained stable for at least 3 weeks under these conditions. MAsIII and DMAsIII generated in UROtsa/F35 cultures were stable for 3 weeks when culture media and cell lysates were stored at −80 °C. These results suggest that samples of cells and tissues represent suitable material for the quantitative, oxidation state-specific analysis of As in laboratory and population studies examining the metabolism or toxic effects of this metalloid.

description: Recently, interface has been employed to enhance superconductivity in the single-layer FeSe films grown on SrTiO3(001)(STO) with a possible Tc of ~ 80 K, which is nearly ten times of the Tc of bulk FeSe and is above the Tc record of 56 K for the bulk Fe-based superconductors. This work together with those on superconducting oxides interfaces revives the long-standing idea that electron pairing at a two-dimensional (2D) interface between two different materials is a potential path to high transition temperature (Tc) superconductivity. Subsequent angle-resolved photoemission spectroscopy (ARPES) measurements revealed different electronic structure from those of bulk FeSe with a superconducting-like energy gap closing at around 65K. However, previous ex situ electrical transport measurements could only detect the zero-resistance below ~30 K. Here we report the observation of high Tc superconductivity in the FeSe/STO system. By in situ 4-point probe (4PP) electrical transport measurement that can be conducted at an arbitrary position of the FeSe film on STO, we detected superconductivity above 100 K. Our finding makes FeSe/STO the exciting and ideal research platform for higher Tc superconductivity.

Validity Concerns With Multiplying Ordinal Items Defined by Binned Counts: An Application to a Quantity-Frequency Measure of Alcohol Use
Creators: name: Curran, Patrick J.
name: McGinley, James S.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries

description: Social and behavioral scientists often measure constructs that are truly discrete counts by collapsing (or binning) the counts into a smaller number of ordinal responses. While prior quantitative research has identified a series of concerns with similar binning procedures, there has been a lack of study on the consequences of multiplying these ordinal items to create a desired index. This measurement strategy is incorporated in many research applications, but it is particularly salient in the study of substance use where the product of ordinal quantity (number of drinks) and frequency (number of days) items is used to create an index of total consumption. In the current study, we demonstrate both analytically and empirically that this multiplicative procedure can introduce serious threats to construct validity. These threats, in turn, directly impact the ability to accurately measure alcohol consumption.

After each pilot course, participants and organisers were invited to complete a brief questionnaire on different aspects of the courses and to provide comments or suggestions for further development and improvement.
Accelerated nuclei preparation and methods for analysis of histone modifications in yeast

Year: 2006

description: The continuing identification of new histone post-translational modifications and ongoing discovery of their roles in nuclear processes has increased the demand for quick, efficient, and precise methods for their analysis. In the budding yeast Saccharomyces cerevisiae, a variety of methods exist for the characterization of histone modifications on a global scale. However, a wide gap in preparation time and histone abundance exists between the most widely used extraction methods, a simple whole cell extraction (WCE) and an intensive histone extraction. In this work we evaluate various published WCE buffers for their relative effectiveness in the detection of histone modifications by western blot analysis. We also present a precise, yet time-efficient method for the detection of subtle changes in histone modification levels. Lastly, we present a protocol for the rapid small-scale purification of nuclei that improves the performance of antibodies that do not work efficiently in WCE, and aids in the detection of histone modifications that are low in abundance. These new methods are ideal for the analysis of histone modifications and could be applied to the analysis and improved detection of other nuclear proteins.

Purification of histone demethylases from HeLa cells
Creators: name: ZHANG, Y
name: TSUKADA, Y
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2006

description: Posttranslational histone modifications play an important role in regulating chromatin dynamics and function. One of the modifications, methylation, occurs on both lysine and arginine residues and participates in diverse range of biological processes including heterochromatin formation, X-chromosome inactivation, and transcriptional regulation. While acetylation, phosphorylation, and ubiquitylation are dynamically regulated by enzymes that catalyze the addition and removal of a particular modification, enzymes that are capable of removing methyl groups were not known until recently. Thus far, two families of histone demethylases with distinct cofactor requirements and reaction mechanisms have been identified. One is the FAD (flavin adenine dinucleotide)-dependent amine oxidase family LSD1 (lysine specific demethylase), the other is the Fe(II) and α-KG (α-ketoglutarate)-dependent dioxygenase family JHDM (JmjC domain-containing histone demethylase). Identification and characterization of these histone demethylases is an important step towards understanding both the function and regulation of histone methylation. Here, we describe assays currently used for measuring histone demethylase activity and chromatography strategies used in purifying histone demethylases from HeLa cells.

The corresponding methods are applied to the study of statistical properties of pyramidal islands formation with interacting adsorbate at epitaxial growth. Using the generalized kinetic approach we consider universality, scaling dynamics and fractal properties of pyramidal islands growth. In the framework of generalized kinetics, we propose a theoretical model to examine the numerically obtained data for averaged islands size, the number of islands and the corresponding universal distribution over the island size.

Using Map of Life to Investigate Species Ranges Shifts with Climate Change
Creators: name: Campany, Courtney
Publisher: name: QUBES Educational Resources
Year: 2023

description: Biodiversity databases, based on species occurrences, are now readily available for students to use a free of charge. These databases allow exploration of how species ranges shift through time. One of these tools, Map of Life, has integrated Shared Socioeconomic Pathways (SSPs) to project species occurrences and ranges (based on suitable habitat) through 2070. The different SSPs use variable greenhouse gas emissions scenarios with different climate policies, ranging from sustainable futures to fossil-fueled development. This activity first allows students to explore current ranges and suitable habitat of individual species, globally. Then, students use different SSPs to investigate future projections of species ranges and relate changes in range size to suitable habitat and life history traits.

description: Blood vessel morphology (vessel radius, branching pattern, and tortuosity) is altered by a multitude of diseases. Although murine models of human pathology are important to the investigation of many diseases, there are few publications that address quantitative measurements of murine vascular morphology. This report outlines methods of imaging mice in vivo using magnetic resonance angiograms obtained on a clinical 3T unit, of defining mouse vasculature from these images, and of quantifying measures of vessel shape. We provide examples of both healthy and diseased vasculature and illustrate how the approach can be used to assess pathology both visually and quantitatively. The method is amenable to the assessment of many diseases in both human beings and mice.

description: Ameliorating the lifetime in heterogeneous wireless sensor network is an important task because the sensor nodes are limited in the resource energy. The best way to improve a WSN lifetime is the clustering based algorithms in which each cluster is managed by a leader called Cluster Head. Each other node must communicate with this CH to send the data sensing. The nearest base station nodes must also send their data to their leaders, this causes a loss of energy. In this paper, we propose a new approach to ameliorate a threshold distributed energy efficient clustering protocol for heterogeneous wireless sensor networks by excluding closest nodes to the base station in the clustering process. We show by simulation in MATLAB that the proposed approach increases obviously the number of the received packet messages and prolongs the lifetime of the network compared to TDEEC protocol.

description: The binding of sequence-specific regulatory factors and the recruitment of chromatin remodeling activities cause nucleosomes to be evicted from chromatin in eukaryotic cells. Traditionally, these active sites have been identified experimentally through their sensitivity to nucleases. Here we describe the details of a simple procedure for the genome-wide isolation of nucleosome-depleted DNA from human chromatin, termed FAIRE (Formaldehyde Assisted Isolation of Regulatory Elements). We also provide protocols for different methods of detecting FAIRE-enriched DNA, including use of PCR, DNA microarrays, and next-generation sequencing. FAIRE works on all eukaryotic chromatin tested to date. To perform FAIRE, chromatin is crosslinked with formaldehyde, sheared by sonication, and phenol-chloroform extracted. Most genomic DNA is crosslinked to nucleosomes and is sequestered to the interphase, whereas DNA recovered in the aqueous phase corresponds to nucleosome-depleted regions of the genome. The isolated regions are largely coincident with the location of DNaseI hypersensitive sites, transcriptional start sites, enhancers, insulators, and active promoters. Given its speed and simplicity, FAIRE has utility in establishing chromatin profiles of diverse cell types in health and disease, isolating DNA regulatory elements en masse for further characterization, and as a screening assay for the effects of small molecules on chromatin organization.

description: Molecular outflows are a direct consequence of accretion, and therefore they represent one of the best tracers of accretion processes in the still poorly understood early phases of high-mass star formation. Previous studies suggested that the SiO abundance decreases with the evolution of a massive young stellar object probably because of a decay of jet activity, as witnessed in low-mass star-forming regions. We investigate the SiO excitation conditions and its abundance in outflows from a sample of massive young stellar objects through observations of the SiO(8-7) and CO(4-3) lines with the APEX telescope. Through a non-LTE analysis, we find that the excitation conditions of SiO increase with the velocity of the emitting gas. We also compute the SiO abundance through the SiO and CO integrated intensities at high velocities. For the sources in our sample we find no significant variation of the SiO abundance with evolution for a bolometric luminosity-to-mass ratio of between 4 and 50 $L_\odot/M_\odot$. We also find a weak increase of the SiO(8-7) luminosity with the bolometric luminosity-to-mass ratio. We speculate that this might be explained with an increase of density in the gas traced by SiO. We find that the densities constrained by the SiO observations require the use of shock models that include grain-grain processing. For the first time, such models are compared and found to be compatible with SiO observations. A pre-shock density of $10^5\, $cm$^{-3}$ is globally inferred from these comparisons. Shocks with a velocity higher than 25 km s$^{-1}$ are invoked for the objects in our sample where the SiO is observed with a corresponding velocity dispersion. Our comparison of shock models with observations suggests that sputtering of silicon-bearing material (corresponding to less than 10% of the total silicon abundance) from the grain mantles is occurring.

description: We report a fully general technique addressing a long standing challenge of calculating conformational free energy differences between various states of a polymer chain from simulations using explicit solvent force fields. The main feature of our method is a special mapping variable, a path coordinate, which continuously connects two conformations. The path variable has been designed to preserve locality in the phase space near the path endpoints. We avoid the problem of sampling the unfolded states by creating an artificial confinement “tube” in the phase space that prevents the molecule from unfolding without affecting the calculation of the desired free energy difference. We applied our technique to compute the free energy difference between two native-like conformations of the small protein Trp-cage using the CHARMM force field with explicit solvent. We verified this result by comparing it with an independent, significantly more expensive calculation. Overall, the present study suggests that the new method of computing free energy differences between polymer chain conformations is accurate and highly computationally efficient.

description: The purpose of this research experiment was to explore and implement a cost-effective automation solution into a low volume production line for loading parts onto a coordinate measuring machine (CMM) for dimensional inspection. Quality control practices have historically been separated from production process by inspection routines being performed in a controlled lab. The system demonstrated the possibilities of an in-process automation of the quality control process that was feasible to be implemented for small and mid-sized manufacturing companies. The process involved an APSX horizontal injection mold machine dispensing parts onto the conveyor belt. The conveyor belt was controlled by a Phoenix Contact PLC and two line sensors that provided two stopping point for cooldown before inspection. A MyCobot 320-M5 robotic arm was used to select the part off the line and places it into a fixture on a Hexagon coordinate measuring machine (CMM).
