description: We study anomalous mesoscopic transport effects at the onset of the superconducting transition focusing on the observed large Nernst-Ettinghausen signal in disordered thin films. In the vicinity of the transition, as the Ginzburg-Landau coherence length of preformed Cooper pairs diverges, short-range mesoscopic fluctuations are equivalent to local fluctuations of the critical temperature. As a result, the dynamical susceptibility function of pair propagation acquires a singular mesoscopic component, and consequently, superconducting correlations give rise to enhanced mesoscopic fluctuations of thermodynamic and transport characteristics. In contrast to disordered normal metals, the root-mean-square value of mesoscopic conductivity fluctuations ceases to be universal and displays strong dependence on dimensionality, temperature, and under certain conditions can exceed its quantum normal state value by a large factor. Interestingly, we find different universality as magnetic susceptibility, conductivity, and transverse magnetic thermopower coefficients all display the same temperature dependence. Finally, we discuss an enhancement of mesoscopic effects in the Seebeck thermoelectricity and Hall conductivity fluctuations as mediated by emergent superconductivity.

description: Apart from carrying genetic information, RNAs also act as effectors of cellular processes through folding into intricate secondary and tertiary structures. The ubiquitous RNA structures in eukaryotic mRNAs, in collaboration with specific RNA-binding proteins, control many aspects of the post-transcriptional regulation of gene expression. However, the molecular bases for the recognition of these mRNA structures by their protein partners remain poorly understood due to the lack of structural information.
      This dissertation presents our structural studies on two protein-RNA complexes that both include regulatory mRNA stem-loop structures. We first describe the crystal structure of a ternary complex including the highly conserved human histone mRNA stem-loop (SL), the stem-loop binding protein (SLBP) and the 3′ to 5′ exonuclease 3′hExo. This structure identifies a single sequence-specific interaction between the SL and SLBP, and the mostly shape-dependent RNA-recognition mode by both proteins. In addition to explaining the large body of biochemical and biophysical data on this complex accumulated over the last two decades, we also for the first time elucidate the induced-fit mechanism underlying the cooperativity between SLBP and 3′hExo. We next shift our focus to a class of less conserved mRNA stem-loop structures named constitutive decay elements (CDE). The RNA-binding ROQ domain of Roquin recognizes the various CDEs and mediates the decay of CDE-containing mRNAs, which predominantly encode proteins responsible for inflammation and autoimmunity. Structural and biochemical studies of the ROQ domain in complex with two different CDE RNAs unexpectedly reveal two distinct RNA binding sites on this protein, one recognizing CDE stem-loops and the other binding to double-stranded RNAs. The stuctures are also in agreement with the versatility of Roquin and have opened up new avenues to investigating its functions in modulating the stability of target mRNAs.
The Turnover of Tenants on the Ashburnham Estate, 1830-1850

description: Sussex Archaeological Collections, 113, 157-174
description: A problem facing the Earl of Ashburnham in the mid-nineteenth century was the relatively rapid rate of turnover by his tenant farmers on his High Wealden estate in Sussex. An examination is made of a number of interlinked general factors such as the relatively poor physical environment, low farming standards, and conditions of tenure, all of which effectively hindered the stability of tenants. The quality of management varied greatly between farms and the importance of obtaining an experienced tenant with capital was crucial, since his improvements could then be furthered by his successors to produce a cumulative beneficial effect.

description: The purpose of this paper is to study the approximation of vector valued mappings defined on a subset of a normed space. We investigate Korovkin-type conditions under which a given sequence of linear operators becomes a so-called approximation process. First, we give a sufficient condition for this sequence to approximate the class of bounded, uniformly continuous functions. Then we present some sufficient and necessary conditions guaranteeing the approximation within the class of unbounded, *weak-to-norm continuous mappings. We also derive some estimates of the rate of convergence.

description: The large-scale CMB B-mode polarization is the direct probe to the low frequency primordial gravitational wave signal. However, unambiguous measurement of this signal requires a precise understanding of the possible contamination. One such potential contamination arises from the patchiness in the spatial distribution of free electrons during the epoch of reionization. We estimate the B-mode power spectrum due to patchy reionization using a combination of \emph{photon-conserving} semi-numerical simulation and analytical calculation, and compare its amplitude with the primordial B-mode signal. For a reionization history which is in agreement with several latest observations, we find that a stronger secondary B-mode polarization signal is produced when the reionization is driven by the sources in massive halos and its amplitude can be comparable to the recombination bump for tensor to scalar ratio $(r) \lesssim 5 \times 10^{-4}$. If contamination from patchy reionization is neglected in the analysis of B-mode polarization data, then for the models of reionization considered in this analysis, we find a maximum bias of about $30\%$ in the value of $r=\,10^{-3}$ when spatial modes between $\ell \in [50, 200]$ are used with a delensing efficiency of $50\%$. The inferred bias from patchy reionization is not a severe issue for the upcoming ground-based CMB experiment Simons Observatory, but can be a potential source of confusion for proposed CMB experiments which target to detect the value of $r< 10^{-3}$. However, this obstacle can be removed by utilizing the difference in the shape of the power spectrum from the primordial signal.

description: Phenotypic screening is a powerful technique for discovering small organic molecules with the ability to effect a desired change in biological systems. Yet, because of the diversity of ways that a small molecule can alter a biological system, phenotypic screens provide little to no insight into how a hit molecule elicits such a change. Understanding a molecule’s mechanism of action—which proteins it engages, where it localizes, and its reactivity—is critical to fully developing a hit molecule into a research tool or a therapeutic.  In this dissertation, strategic, hypothesis-driven molecular design is used as a cornerstone technique to understand the mechanism of action of molecules that regulate cell death. In the first part, we examine the structural requirements for ferroptotic death induction by the 1,2-dioxolane FINO2. Next, we create a panel of ferroptosis inhibiting molecules that are targeted to specific organelles and used as imaging agents in order to examine the contribution of different organelles to ferroptosis. I then apply molecular design in a target-based context to discover which molecular features of LOC14 promote association with its receptor protein. Finally, I discuss a computational approach to developing a ligand that inhibits protein-protein interactions mediated by the small GTPase Rheb.

description: Although the Dunstanvilles are not well known as a Sussex family, they were established in the county throughout the 12th and 13th centuries and illustrate the opportunities and pitfalls that might confront the Anglo-Norman elite. Walter de Dunstanville accumulated property holdings both inside the county and in Shropshire and Wiltshire, inheriting from a variety of family members during a career spanning nearly 40 years, but he never received more than fleeting royal favour. Towards the end of his life his political misjudgements brought the family fortunes close to collapse and he died leaving only a single child, a small son, as his heir.

description: Blockchain is a disruptive technology that has been characterised to be the next big thing and has already gained a broad recognition by experts in diverse fields. In this paper, we consider possible use cases and applications of the blockchain for the consumer electronics (CE) industry and its interplay with the Internet of things. Instead of discussing how the blockchain can revolutionise the supply chain, we focus on how it could be employed for enhancing the security of networked CE devices. This work is motivated by the large number of recent attacks that use easily hackable devices as a weaponry. Towards this direction, privacy and data protection aspects of blockchain solutions are also presented and are linked to regulatory framework provisions. Information on existing blockchain solutions is also provided.

description: Autophagy is the process by which cells eliminate its unwanted or dysfunctional components. A major step in autophagy is the formation of autophagosome, the double membrane that engulfs the unwanted cellular components. Dysregulation of autophagy affects neurodegenerative disorders, infectious diseases, cancer, and aging. In yeast, Atg8 protein is considered to play a crucial role in autophagosome maturation. Studies have shown that yeast lacking Atg8 protein form extremely small autophagosomes. Similarly, mammalian cells lacking Atg8 homologues produced “open” autophagosomes. Microtubule-associated protein (MAP) light chain3 (LC3), a human homologue of Atg8 protein is considered to play a major role in autophagosome maturation. However the exact mechanism by which Atg8/LC3 affects the autophagosome maturation is not completely known. A possible mechanism evolving from various studies is the following: Upon binding to the autophagosome, Atg8 family undergoes a conformational transition, which allows it to associate with another membrane-bound Atg8 in a trans-fashion. The proposed goals of this research include testing this hypothesis, identifying the stable conformations of LC3 and LC3-II (membrane bound LC3) and getting insights into the molecular mechanism by which LC3 influence autophagosome maturation. To accomplish this, we are performing Hamiltonian replica exchange molecular dynamics (HREMD) simulations on LC3 and on LC3-II. The most stable conformations of LC3, and LC3-II are identified via clustering analysis. As autophagy modulation is considered as a potential therapeutic target for various diseases, understanding the molecular mechanisms of different stages of autophagy is very important.

Molecular Mechanisms Controlling Synaptic Vesicle Fusion
Creators: Radoff, Daniel Todd
Publisher: name: Columbia University
Year: 2011
Subjects: Biochemistry

description: SNARE proteins are the engines that drive membrane fusion throughout the cell.  They provide this energy by zippering up into a parallel four helix bundle in a thermodynamically favored process. Because the zippering of SNAREs is spontaneous, fusion events occur immediately upon a vesicle interacting with its target membrane. But, in certain circumstances, such as in synaptic vesicles, spontaneous fusion is not desired, so a clamp protein is necessary to prevent this fusion until signaled to do otherwise.  In synapses, this protein is called Complexin and a second protein, called Synaptotagmin, releases the clamp upon a rapid influx of calcium, the hallmark of an action potential.  How Complexin clamps is a subject of great interest in the field, and an area of active research. What is known is that a so-called Accessory helix (residues 28-47) is responsible for clamping, while another, Central Helix (reisudes 48-70) is responsible for physically binding to the helix.  A recently solved crystal structure revealed how CPX might behave before the SNAREs fully zipper, namely that the accessory helix extends away from the SNAREs at a 45° angle.  But, because of the packing of the crystal, it is entirely possible that the crystal is an artifact of packing, and/or truncationIn this thesis, my work first validates the crystal structure, using a FRET pair I developed for this purpose.  I establish that the angled-out positioning of the accessory helix does, in fact, occur in solution, and is not due to crystal packing or the truncation of the VAMP2 (the neuronal vesicle-associated SNARE), but rather is due to the fact that its C-terminus is not present.  I describe a mechanism by which Complexin can clamp.  Further, I demonstrate that the residues in VAMP2 which are responsible for the switch from the "open" to the "closed" conformation are a patch of asparatates in VAMP2 (residues 64, 65, an 68).  I also establish that these three aspartates are responsible for the release of the clamp and that without them, Complexin cannot be brought into the angled-in configuration. I propose a model for how the clamp might be released by Synaptotagmin.

description: From a direct numerical simulation of the MHD equations we show, for the first time, that velocity and magnetic-field structure functions exhibit multiscaling, extended self similarity (ESS), and generalized extended self similarity (GESS). We also propose a new shell model for homogeneous and isotropic MHD turbulence, which preserves all the invariants of ideal MHD, reduces to a well-known shell model for fluid turbulence for zero magnetic field, has no adjustable parameters apart from Reynolds numbers, and exhibits the same multiscaling, ESS, and GESS as the MHD equations. We also study dissipation-range asymptotics and the inertial- to dissipation-range crossover.

description: Obesity has a multifactorial etiology and is known to be a state of chronic low-grade inflammation, known as meta-inflammation. This state is associated with the development of metabolic disorders such as glucose intolerance and nonalcoholic fatty liver disease. Pyruvate is a glycolytic metabolite and a crucial node in various metabolic pathways. However, its role and molecular mechanism in obesity and associated complications are obscure. In this study, we reported that pyruvate substantially inhibited adipogenic differentiation in vitro and its administration significantly prevented HFD-induced weight gain, white adipose tissue inflammation, and metabolic dysregulation. To identify the target proteins of pyruvate, drug affinity responsive target stability was employed with proteomics, cellular thermal shift assay, and isothermal drug response to detect the interactions between pyruvate and its molecular targets. Consequently, we identified cytosolic phospholipase A2 (cPLA2) as a novel molecular target of pyruvate and demonstrated that pyruvate restrained diet-induced obesity, white adipose tissue inflammation, and hepatic steatosis in a cPLA2-dependent manner. Studies with global ablation of cPLA2 in mice showed that the protective effects of pyruvate were largely abrogated, confirming the importance of pyruvate/cPLA2 interaction in pyruvate attenuation of inflammation and obesity. Overall, our study not only establishes pyruvate as an antagonist of cPLA2 signaling and a potential therapeutic option for obesity, but it also sheds light on the mechanism of its action. Pyruvate's prior clinical use indicates that it can be considered a safe and viable alternative for obesity, whether consumed as a dietary supplement or as part of a regular diet.

The geometrical formulation of this nonrelativistic theory of gravity, pioneered by Cartan and further developed by various workers, leads to a conceptually sound basis of Newtonian cosmology. In our discussion of homogeneous models and cosmological perturbation theory, we stress the close relationship with their general relativistic treatments. Spatially compact flat models also fit into this framework.

description: We notice signatures of extreme events-like behavior in a laser based Ikeda map. The trajectory of the system occasionally travels a large distance away from the bounded chaotic region, which appears as intermittent spiking events in the temporal dynamics. The large spiking events satisfy the conditions of extreme events as usually observed in dynamical systems. The probability density function of the large spiking events shows a long-tail distribution consistent with the characteristics of rare events. The inter-event intervals obey a Poisson-like distribution. We locate the parameter regions of extreme events in phase diagrams. Furthermore, we study two Ikeda maps to explore how and when extreme events terminates via mutual interaction. A pure diffusion of information exchange is unable to terminate extreme events where synchronous occurrence of extreme events is only possible even for large interaction. On the other hand, a threshold-activated coupling can terminate extreme events above a critical value of mutual interaction.

description: Due to the complex interplay of magnetic, structural, electronic, and orbital degrees of freedom, biaxial strain is known to play an essential role in the doped manganites. For coherently strained La(2/3)Ca(1/3)MnO(3) thin films grown on SrTiO(3) substrates, we measured the magnetotransport properties both parallel and perpendicular to the substrate and found an anomaly of the electrical transport properties. Whereas metallic behavior is found within the plane of biaxial strain, for transport perpendicular to this plane an insulating behavior and non-linear current-voltage characteristics (IVCs) are observed. The most natural explanation of this anisotropy is a strain induced transition from an orbitally disordered ferromagnetic state to an orbitally ordered state associated with antiferromagnetic stacking of ferromagnetic manganese oxide planes.

description: On their own, SAF and hydrogen aircraft are not the solution to aviation's climate problems (as conveyed by industry). E-fuels are needed rather than biofuels. E-fuels must be made from CO2 from the atmosphere (extracted by Direct Air Capture, DAC). Unfortunately, the renewable energy demand for aviation's e-fuel is higher than its availability. Any small progress is immediately compensated by traffic growth. Flying less is a fundamental solution that works! Passengers need to get informed (with an Ecolabel), need to decide if they want to travel at all, if they want to take the aircraft (or another mode of transport), and which aircraft and airline to select. Passenger are in a strong position. Passengers can vote with their feet! ReFuelEU, Article 14 "Environmental Labeling Scheme" is very promising, but some changes would be helpful. EASA has started with its "Environmental Labeling Scheme for Aviation". EASA's progress seems slow. EASA partnered with Google. Google has already a good solution: https://flights.google.com. HAW Hamburg has an Ecolabel for Aircraft ready and is working on its Airline Label and Flight Label.

description: Bottom-up molecular synthesis is a route to chemically and crystallographically uniform polymers and solid-state materials. Through the use of molecular precursors, we gain atomic-level control of functionality and fine-tuning of the collective properties of materials. This dissertation presents two studies that demonstrate this approach.
      Ring-opening alkyne metathesis polymerization is a possible approach to monodisperse conjugated polymers, but its applications have been limited by difficult syntheses and high air sensitivity of known organometallic ROAMP initiators. We designed a dimeric, air-stable molybdenum alkylidyne with a tris(phenolate) supporting ligand. The precatalyst is activated by addition of methanol and polymerizes cyclooctynes with excellent chemical selectivity and functional group tolerance.
      The Nuckolls and Roy groups have introduced a new family of solid-state compounds synthesized from cobalt chalcogenide clusters Co6Q8(PR3)6 and fullerenes. The first examples of these materials crystallized in superatom lattices with the symmetry of simple inorganic solids CdI2 (P-3m1) and NaCl (Fm-3m). This dissertation reveals that further members of the family feature extraordinary diversity of structure, including a pseudo-trigonal array of fulleride dimers in [Co6Te8(PEt3)6]2[C140][C70]2 and a heterolayered van der Waals cocrystal [Co6Se8(PEt2phen)6][C60]5. In addition to these unusual crystal structures, this dissertation presents a method for assigning redox states from crystallographic data in Co6Q8 clusters.
      Finally, a detailed guide to the collection and solution of single-crystal X-ray data is presented. The guide is intended for independent study by new crystallographers.

description: The ore and waste rock at Kemess Mine are highly variable and range from having high acid generation potential to high neutralization potential and some of the materials may also leach metals, notably selenium, at neutral pH. The potential environmental impact caused by the storage of ore and waste rock has been reduced to acceptable levels by the integrated materials management program. Management techniques include the ongoing sampling and classification of all rock types on site into 11 categories and the segregation of potentially problematic materials. This segregation requires a considerable effort on the part of mining operations to schedule and monitor waste placement. The materials management program has been successful largely due to the cooperation between the relevant departments at the mine, including Environment, Engineering and Geology, and the level of awareness of operating personnel. This paper provides details on the procedures developed at the Kemess Mine to control impacts. Included are details on the Acid Rock Drainage and metal leaching prediction methods employed and the material handling and segregation procedures use to achieve the required objectives.

description: Let $k$ be a subring of the field of rational functions in $x, v, s$ which contains $x^{\pm 1}, v^{\pm 1}, s^{\pm 1}$. If $M$ is an oriented 3-manifold, let $S(M)$ denote the Homflypt skein module of $M$ over $k$. This is the free $k$-module generated by isotopy classes of framed oriented links in $M$ quotiented by the Homflypt skein relations: (1) $x^{-1}L_{+}-xL_{-}=(s-s^{-1})L_{0}$; (2) $L$ with a positive twist $=(xv^{-1})L$; (3) $L\sqcup O=(\frac{v-v^{-1}}{s-s^{-1}})L$ where $O$ is the unknot. We give two bases for the relative Homflypt skein module of the solid torus with 2 points in the boundary. The first basis is related to the basis of $S(S^1\times D^2)$ given by V. Turaev and also J. Hoste and M. Kidwell; the second basis is related to a Young idempotent basis for $S(S^1\times D^2)$ based on the work of A. Aiston, H. Morton and C. Blanchet. We prove that if the elements $s^{2n}-1$, for $n$ a nonzero integer, and the elements $s^{2m}-v^{2}$, for any integer $m$, are invertible in $k$, then $S(S^{1} \times S^2)=k$-torsion module $\oplus k$. Here the free part is generated by the empty link $ϕ$. In addition, if the elements $s^{2m}-v^{4}$, for $m$ an integer, are invertible in $k$, then $S(S^{1} \times S^2)$ has no torsion. We also obtain some results for more general $k$.

Bayesian Model Selection with Future 21cm Observations of The Epoch of Reionisation

description: We apply Bayesian statistics to perform model selection on different reionisation scenarios via the Multinest algorithm. Initially, we recover the results shown by 21CMMC for the parameter estimation of 21cmFAST models. We proceed to test several toy models of the Epoch of Reionisation (EoR) defined in contrasting morphology and scale. We find that LOFAR observations are unlikely to allow model selection even with long integration times. HERA would require 61 dipoles to perform the same analysis in 1080 hours, and becomes comparable to the SKA with 217 dipoles. We find the SKA requires only 324 hours of observation to conclusively distinguish between our models. Once model selection is achievable, an analysis of observational priors is performed finding that neutral fraction checks at specific redshifts add little to no inference. We show the difficulties in model selection at the level of distinguishing fiducial parameters within a model or distinguishing galaxies with a constant versus power law mass-to-light ratio. Finally, we explore the use of the Savage-Dickey density ratio to show the redundancy of the parameter Rmfp within 21cmFAST.

description: We introduce and study in detail an invariant of (1,1) tangles. This invariant, derived from a family of four dimensional representations of the quantum superalgebra U_q[gl(2|1)], will be referred to as the Links-Gould invariant. We find that our invariant is distinct from the Jones, HOMFLY and Kauffman polynomials (detecting chirality of some links where these invariants fail), and that it does not distinguish mutants or inverses. The method of evaluation is based on an abstract tensor state model for the invariant that is quite useful for computation as well as theoretical exploration.

Periodic orbit quantization of the Sinai billiard in the small scatterer limit

description: We consider the semiclassical quantization of the Sinai billiard for disk radii R small compared to the wave length 2 pi/k. Via the application of the periodic orbit theory of diffraction we derive the semiclassical spectral determinant. The limitations of the derived determinant are studied by comparing it to the exact KKR determinant, which we generalize here for the A_1 subspace. With the help of the Ewald resummation method developed for the full KKR determinant we transfer the complex diffractive determinant to a real form. The real zeros of the determinant are the quantum eigenvalues in semiclassical approximation. The essential parameter is the strength of the scatterer c=J_0(kR)/Y_0(kR). Surprisingly, this can take any value between plus and minus infinity within the range of validity of the diffractive approximation kR <<4. We study the statistics exhibited by spectra for fixed values of c. It is Poissonian for |c|=infinity, provided the disk is placed inside a rectangle whose sides obeys some constraints. For c=0 we find a good agreement of the level spacing distribution with GOE, whereas the form factor and two-point correlation function are similar but exhibit larger deviations. By varying the parameter c from 0 to infinity the level statistics interpolates smoothly between these limiting cases.

description: We analyze the relationship between quasilocal masses calculated for solutions of conformally related theories. We show that the ADM mass of a static, spherically symmetric solution is conformally invariant (up to a constant factor) only if the background action functional is conformally invariant. Thus, the requirement of conformal invariance places restrictions on the choice of reference spacetimes. We calculate the mass of the black hole solutions obtained by Garfinkle, Horowitz, and Strominger (GHS) for both the string and the Einstein metrics. In addition, the quasilocal thermodynamic quantities in the string metrics are computed and discussed.

Probabilistic state transfer, estimation and measures for optimal actuator/sensor placement for linear systems with packet dropouts

description: We consider linear systems subject to packet dropouts and obtain necessary and sufficient conditions for an arbitrary state transfer and state estimation over a finite time instance $T$. The data loss signal is modeled using the Bernoulli random variable. We leverage properties of the Hadamard product in our approach and use the derived necessary and sufficient conditions to compute the probability that an arbitrary state transfer is possible at a specified time instant. Similarly, the probability of finding an exact state estimate is found using the observability counterparts of the results. Using the necessary and sufficient conditions obtained for the invertibility of the Gramian, we give new probabilistic measures for optimal actuator and sensor placement problems and obtain optimal/sub-optimal solutions. We demonstrate by an example how the probabilities of packet dropouts influence the choice of an optimal actuator. We also discuss how to implement feedback laws and the LQR problem for these models involving packet dropouts.
