description: A comparison is made between bispectral systems and dual isomonodromic deformation equations. A number of examples are given, showing how bispectral systems may be embedded into isomonodromic ones. Sufficiency conditions are given for the construction of rational solutions of isomonodromic deformation equations through the Riemann-Hilbert problem dressing method, and these are shown, in certain cases, to reduce to bispectral systems.

In phase I, ossification has not yet begun, and the cranial skeleton is composed of only cartilaginous elements. Sphenethmoid and otic capsules are visible, and the mandible consists exclusively of Meckel’s cartilages. In the pharynx, the basibranchial and the first to third ceratobranchials are observed as cartilaginous structures.
Ossification of the skull begins in phase II. The premaxilla, squamosal, dentary and columella begin to ossify. In some individuals, ossification of the vomer, parasphenoid and prearticular is also detected. An ossification centre is detected in the medial portion of the premaxilla, the anterior portion of the vomer and the posterolateral portion of the parasphenoid. The lateral part of the frontal and parietal bones begins to ossify along the anterior–posterior axis. In the pharynx, the hypohyal, ceratohyal, first and second hypobranchials and fourth ceratobranchial appear as cartilaginous structures.
Ossification of the angular, coronoid and parietal begin in phases III and IV. The coronoid starts to ossify from the medial side and the parietal from the lateral side.
In phase V, ossification of the maxilla, exoccipital and angular begins. The maxilla starts to ossify from the medial side, the exoccipital from the posterior side and the angular from the anterior side. Ossification of the premaxilla and dentary is advanced, and several teeth have developed on these bones.
Bones ossified in each phase are listed in alphabetical order.
In phase VI, ossification begins at the medial side of the nasal, the lateral side of the frontal and the anterior portion of the pterygoid. Ossification of the second ceratobranchial is observed in some individuals.
In phase VII, the prefrontal and the second ceratobranchial are ossified in all individuals. Ossification of the frontal and parietal progresses from the lateral portion to the medial portion during phases VI and VII. A fontanelle and suture lines are observed in the dorsomedial portion of the skull.
In phase VIII, the frontal and parietal are divided by a suture line. The orbitosphenoid begins to ossify.
In phase IX, the third and fourth ceratobranchial disappear.
The second ceratobranchial ossifies in phase XII (the subadult stage). All bone elements present in the skull of the adult (phase XIII) are ossified.

description: Since some raw materials, semi manufactured, intermediate and capital goods in agricultural sector are imported, the exchange rate fluctuations can affect the cost price of products in this sector. Recently, we are facing considerable fluctuations in exchange rate that has an important impact on all sectors including the agriculture. As a result of an increase in import prices in agricultural raw materials, the exchange rate fluctuates. In other words, this relationship is strengthened by lower domestic supply due to the stimulation of the exports of agricultural products induced by an increase in exchange rate. The present study deals with the impact of exchange rate fluctuations on agricultural price index in Iran using MGARCH method. The results show that the past shocks of exchange rate have a positive impact on agriculture price index at the 1% significance level. Moreover, despite the fact that the current fluctuations of agriculture price index do not relate to its past fluctuations, the past fluctuations of exchange rate have a positive impact on current fluctuations of exchange rate.
A simple rule for finding Dirac Cones in Bilayered Perovskites

description: We propose a simple rule for finding Dirac cone electronic states in solids, that is neglecting those lattice atoms inert to the particular electronic bands, and pursuing the two dimensional (2D) graphene-like quasi-atom lattices with s- and p-bindings by considering the equivalent atom groups in the unit cell as quasi-atoms. With CsPbBr$_3$ and Cs$_3$Bi$_2$Br$_9$ bilayers as examples, we demonstrate the effectiveness and generality of this rule with the density functional theory (DFT) calculations. We demonstrate that both bilayers have Dirac cones around the Fermi level and reveal that their corresponding Fermi velocities can reach as high as $\sim$ 0.2$\times$10$^6$m/s. That makes these new 2D layered materials very promising in making new ultra-fast ionic electronic devices.

description: A broad class of generalized Einstein's gravity can be cast into Einstein's gravity with a minimally coupled scalar field using suitable conformal rescaling of the metric. Using this conformal equivalence between the theories, we derive the equations for the background and the perturbations, and the general asymptotic solutions for the perturbations in the generalized Einstein's gravity from the simple results known in the minimally coupled scalar field. Results for the scalar and tensor perturbations can be presented in unified forms. The large scale evolutions for both modes are characterized by corresponding conserved quantities. We also present the normalization condition for canonical quantization.

description: This position paper takes the first step to attempt to present the initial characterization of HCI research in China. We discuss the current streams and methodologies of Chinese HCI research based on two well-known HCI theories: Micro/Marco-HCI and the Three Paradigms of HCI. We evaluate the discussion with a survey of Chinese publications at CHI 2019, which shows HCI research in China has less attention to Macro-HCI topics and the third paradigms of HCI (Phenomenologically situated Interaction). We then propose future HCI research directions such as paying more attention to Macro-HCI topics and third paradigm of HCI, combining research methodologies from multiple HCI paradigms, including emergent users who have less access to technology, and addressing the cultural dimensions in order to provide better technical solutions and support.
Navigating exponentially large spaces in biology : methods for directed evolution and smFRET time series analysis
Creators: Bronson, Jonathan Eiseman
Publisher: name: Columbia University
Year: 2011
Subjects: Chemistry

description: The recent explosion of high throughput technologies in many fields of biology has necessitated the use of sophisticated algorithms to guide experimental design and analyze results. This thesis explores two such fields: directed protein evolution and single molecule fluorescence resonance energy transfer analysis. Although the methodologies and applications of the fields differ greatly, they are both limited by a process which scales exponentially with problem size. In the former case, the problem is determining which combination of amino acids should be mutated to enhance or create protein function. In the latter case, the problem is inferring the number of conformations a molecule explores during an experiment and the probability of being in each state at each time point in the experiment. Methods to address both problems will be presented in this thesis.

This formula can be applied to the study of algebraic integrable systems using Lax pairs, in particular systems associated with Seiberg-Witten theory. However, the formula is much more general and its computation and proof are entirely algebraic.

This implies that uniqueness of the infinite cluster is equivalent to non-decay of connectivity (a.k.a. long-range order). We then derive applications concerning uniqueness in Kazhdan groups and in wreath products, and inequalities for $p_u$.

description: The Institute of Medicine identifies nurses as being in a position to become a powerful force for change in our healthcare system through their leadership. The impostor phenomenon is a psychological pattern in which individuals doubt their skills, talents, or accomplishments, or may have internalized fears of being exposed. In a time when nurse leaders are needed the most, these feelings may prevent nurses from advancing their careers and to lead. While a plethora of studies have examined this phenomenon and its negative impacts to mental health and career progression, there is little on the experience among nurses and none among nursing leaders or how to manage it effectively. Fellows of the American Academy of Nurses are considered nursing’s most accomplished leaders in education, management, practice, and research. These successful leaders have been recognized for their extraordinary contributions to nursing and health care. This qualitative study used a phenomenological method designed to gain insight into how these successful leaders have experienced impostor feelings. Ten nurse leaders were interviewed about their career progression, and their experiences with the impostor phenomenon were revealed. Findings were analyzed and the six essential themes that were illuminated from those shared experiences were: (a) Welcoming Opportunities, (b) Extended Sphere of Support, (c) Willingness to be Courageous, (d) Embracing the Journey, (e) Willingly Expressing Humility and Authenticity, and (f) Navigating the Impostor Process. The findings from this study will contribute to the body of knowledge about the impostor phenomenon within the context of the nursing profession and leadership and may benefit other nursing professionals experiencing similar feelings to mitigate them.

description: We present an \textit{ab initio} theory for superconductors, based on a unique mapping between the statistical density operator at equilibrium, on the one hand, and the corresponding one-body reduced density matrix $γ$ and the anomalous density $χ$, on the other. This new formalism for superconductivity yields the existence of a universal functional $\mathfrak{F}_β[γ,χ]$ for the superconductor ground state, whose unique properties we derive. We then prove the existence of a Kohn-Sham system at finite temperature and derive the corresponding Bogoliubov-de Gennes-like single particle equations. By adapting the decoupling approximation from density functional theory for superconductors we bring these equations into a computationally feasible form. Finally, we use the existence of the Kohn-Sham system to extend the Sham-Schlüter connection and derive a first exchange-correlation functional for our theory. This reduced density matrix functional theory for superconductors has the potential of overcoming some of the shortcomings and fundamental limitations of density functional theory of superconductivity.

Ossification has not started in phases I–VI. The sphenethmoid, otic capsule and exoccipital are still cartilaginous.The Meckel’s cartilages, first and second basibranchials, ceratohyal, hypohyal, first and second hypobranchials and first to fourth ceratobranchials are present as cartilaginous elements.
Phases VIII and IX are the earliest stages of ossification in this species. In phase VIII, the posterior part of the exoccipital begins to ossify. In phase IX, the lateral portion of the parietal starts to ossify.
In phase X, the anterior portions of the premaxilla and vomer start to ossify. The bones of the posterior skull (the parietal, squamosal, pterygoid, quadrate, prootic, opisthotic and columella) also begin to ossify. The pterygoid and parietal start to ossify from the posterior side. In the mandible, the dentary ossifies from the anteromedial side, and the medial part of the prearticular ossifies. Ossification of the angular, coronoid and articular are observed in some individuals. In the pharynx, ossification of the previously cartilaginous second hypobranchial has begun. The first and second basibranchials fuse to form a Y-shape. The fourth ceratobranchial disappears. The posterior part of the third ceratobranchial ossifies in some individuals.
In phase XI, the bones of the anterior skull (the maxilla, frontal, nasal, parasphenoid and orbitosphenoid) begin to ossify. The parietal begins to ossify from the anterolateral side and the parasphenoid from the medial side. Suture lines appear between the skull bones.
In phases XII and XIII, the fontanelle closes. In the pharynx, ossification of the anterior part of the second ceratobranchial begins in phase XII, and it is completely ossified in adults (phase XIII). The previously Y-shaped basibranchial becomes 8-shaped.

Hurricane Katrina (2005)
Disaster relief

description: On August 29, 2005, Hurricane Katrina struck the coast of the Gulf Coast of Mexico and devastated broad swathes of Louisiana, Mississippi, and Alabama. The Hurricane itself was designated a Category 3 Storm at landfall, yet it was the unprecedented extend of its aftermath that marked the event as the costliest natural disaster — and one of the five deadliest hurricanes — in the history of the United States. The storm dealt its most devastating blow indirectly to the City of New Orleans, Louisiana, where it triggered the most significant human tragedy as eighty percent of the city flooded when the engineered levee systems failed. This thesis acknowledges the human dimension of the event by examining the impact of the disaster on the physical built environment of three New Orleans neighborhoods that contribute part of the city's historic landscape. The storm, and its prolonged aftermath, altered the cultural landscape of the city — destroying entire neighborhoods, displacing whole communities, and jarring the city's identity. This thesis uses the event of Hurricane Katrina, and its aftermath, to reflect on how the legal frameworks of preservation have shaped the city of New Orleans and how they continue to reshape the city. The goal of this thesis is three-fold. To examine the preservation frameworks in place before the disaster and to identify New Orleans's particular sense of place. To discuss how these frameworks have been impacted following the disaster. And, to think about how the new and old frameworks reshape the city — engaging new constituencies in preservation, and broadening an understanding of what is "historic" in New Orleans.
Closure and sustainability initiatives leading to the reopening of the Gibraltar Mine
Creators: name: Patterson, R. J.

Publisher: name: The University of British Columbia
Year: 2009

description: The Gibraltar Mine, which resumed production in October 2004, was known as a swing producer during its years of operation from 1972 to 1998 – delivering some excellent profits when copper prices were high but experiencing shutdowns when prices dropped. During an extended closure between December 1998 and October 2004, mine staff worked with two levels of government to initiate some creative programs to help sustain the operation through lower parts of the price cycle. One of the prime considerations of closure planning is to provide for the long-term environmental security of the site. Ideally mining companies strive towards a program that will require minimal maintenance, control and monitoring of the site, leading to the ultimate release of long-term liability. In more recent years, especially for mines with water quality issues, this relinquishment of long-term responsibility is unlikely, and large security bonds are now required by government. These security bonds insure an on-going sustainable fund to maintain the site. During the closure period, Gibraltar had posted reclamation security which included $17 million in a cash deposit and an asset security agreement for a further $13 million. There was a further unfunded liability of $12 million which government accepted as a risk. For small companies such as Gibraltar to maintain a presence at these mines, there is an incentive for both the company and government to make use of the existing infrastructure to create alternate businesses. Gibraltar has embarked on an aggressive program to look for alternative business ventures which generate revenue, to both lower the risk of default, and to offset long-term bonding arrangements. Projects being considered or in the works are a solid waste landfill to be located on top of a waste rock dump, a power generation project, metallurgical test work, maintenance work in existing shops, ranching and the possible development of a hydrometallurgical refinery plant that will operate long after reserves at the Gibraltar site are depleted. As a final innovation, Gibraltar was able to raise $17.6 million by independent investors by way of a Qualified Environmental Trust which allowed government to release the $17 million cash deposit to help finance the mine restart.

description: We derive a Feynman-Hellmann theorem relating the second-order nucleon energy shift resulting from the introduction of periodic source terms of electromagnetic and isovector axial currents to the parity-odd nucleon structure function $F_3^N$. It is a crucial ingredient in the theoretical study of the $γW$ and $γZ$ box diagrams that are known to suffer from large hadronic uncertainties. We demonstrate that for a given $Q^2$, one only needs to compute a small number of energy shifts in order to obtain the required inputs for the box diagrams. Future lattice calculations based on this approach may shed new light on various topics in precision physics including the refined determination of the Cabibbo-Kobayashi-Maskawa matrix elements and the weak mixing angle.

description: This paper describes the design and implementation of a minimally hazardous, environmentally friendly, and energy efficient sequential reaction sequence within a sophomore level Organic Chemistry lab course to efficiently synthesize N-phenylmaleimide precursors for a Diels–Alder reaction. Substituted N-phenylmaleimides are a class of very expensive precursors of considerable interest due to their biological properties and use as intermediates in synthesis. The synthesis described herein produces a substituted N-phenylmaleimide in two steps from maleic anhydride and a substituted aniline followed by its Diels–Alder reaction with 2,5-dimethylfuran. The experiment exposes students to the green chemistry principles of atom economy, use of safer chemicals, design for energy efficiency, waste reduction, and inherently safer chemistry for accident prevention and enables students to use 1H NMR spectroscopy to characterize the products.
Phase separation in effective hard-core boson and triplet models in one and two dimensions

description: Effective models of hard-core hole pair bosons and triplets are derived from the t-J model in ladders and on the square lattice by performing a change from site to dimer basis. The Hilbert space is truncated by projecting out single-occupied electron states and only nearest neighbor interactions are retained. The resulting effective models in one and two dimensions are studied by numerical techniques. In both spatial dimensions, the main result is that each hole pair is surrounded by a singlet cloud expelling triplet excitations from its vicinity. It is suggested an interpretation of this feature as a phase separated state between a hole-pair rich singlet phase and an undoped triplet phase with antiferromagnetic correlations. The possible relevance of this result to other theoretical scenarios and experimental results is discussed.

description: Let $M$ be a graph manifold such that each piece of its JSJ decomposition has the $\Bbb H^2 \times \Bbb R$ geometry. Assume that the pieces are glued by isometries. Then, there exists a complete Riemannian metric on $\Bbb R \times M$ which is an "eventually warped cusp metric" with the sectional curvature $K$ satisfying $-1 \le K <0$. A theorem by Ontaneda then implies that $M$ appears as an end of a 4-dimensional, complete, non-compact Riemannian manifold of finite volume with sectional curvature $K$ satisfying $-1 \le K <0$.

description: Lesbian, gay, bisexual, trans, queer, and intersex (LGBTQI) youth straddle a fine line between childhood and adulthood that can make accessing support and exerting independence challenging and complex. Legal definitions based on age are fluid and are nether grounded in neuroscience nor consistently applied. For LGBTQI youth who engage in exchanging sex, navigating systems of support may be infinitely more complicated since ambiguities in the law create a framework in which youth engaged in exchanging sex may be designated both a victim and a criminal. This influences the dominant narratives which situate LGBTQI young people who engage in exchanging sex between static and opposing narratives - vulnerable or at-risk youth in need of protection versus risky or deviant youth engaged in criminal behavior. These narratives lead to a structural incoherence emphasizing youth’s presumed deficits resulting in unintended barriers for the institutions who aim to support them. Through exploratory qualitative research centered on learning from young people as experts in their own lives and experiences, this study highlights the resilient and strategic ways that LGBTQI youth navigate their environments and a complex web of support services. Data from this research suggest that in an environment where youth can be criminalized, service providers may be not be as effective at meeting the needs of this population whom they aim to serve. By approaching youth from a strength-based perspective, researchers and advocates alike can better support LGBTQI youth who engage in exchanging sex.

description: An algebra of functions on q-deformed Anti-de Sitter space AdS_q^D is defined which is covariant under U_q(so(2,D-1)), for q a root of unity. The star-structure is studied in detail. The scalar fields have an intrinsic high-energy cutoff, and arise most naturally as fields on orbifolds AdS_q^D \times S^D/G if D is odd, and AdS_q^D \times S_χ^{2D-1}/G if D is even. Here G is a finite abelian group, and S_χ is a certain ``chiral sector'' of the classical sphere. Hilbert spaces of square integrable functions are discussed. Analogous results are found for the q-deformed sphere S_q^D.

description: Thermal radiation is ubiquitous to all matter at finite temperature and controlling the radiative nature of that matter has been a key enabling factor in the development of several recent technologies, such as thermal diodes, thermal antennae, thermophotovoltaics, heat-assisted magnetic recording, and contactless cooling in microelectromechanical systems. At the micro/nano-scale, thermal radiation does not reliably behave in the way Planck's blackbody law predicts, due to near-field effects such as the diffraction, interference, and tunneling of light. In fact, the so-called blackbody limit can routinely be broken by several orders of magnitude when objects of dimensions or separation distances much smaller than the peak thermal wavelength (approximately 10 \si{\micro\meter} at room temperature) exchange thermal radiation. A deeper theory is required to understand near-field thermal radiation: Maxwell's equations. Maxwell's equations allow for a direct connection between the thermally induced current fluctuations and radiative transfer.
      In this dissertation, I investigate radiative transfer among spherical bodies aligned in a linear chain. The chain may be composed of any number of spheres, and the spheres themselves may be composed of any linear isotropic material, may be of any size and separation distance, and may each have any number of spherically symmetric layers. Using a dyadic Green's function formalism, I derive numerically exact formulas for heat transfer between pairs of spheres in the chain and between any sphere in the chain and its environment.
      My work clearly demonstrates that adding coatings to spherical objects can drastically impact the spectrum of radiative transfer, enhancing or diminishing it in various cases. This degree of tailoring makes coated spheres a flexible, yet unexplored, platform for future experiments in near-field radiative heat transfer. My work also demonstrates that, in an experiment measuring the distance dependent heat transfer between two spheres, heat transfer from the spheres to their environment can also have a strong distance dependence, which must be considered carefully when designing an experiment and analyzing its results. This demonstrates a cautious but optimistic outlook for the near-field radiative heat transfer community moving beyond traditional plane-plane and sphere-plane experimental configurations.

description: Using the Born-Oppenheimer approximation, we show that exotic resonances, X and Z, may emerge as QCD molecular objects made of colored two-quark lumps, states with heavy-light diquarks spatially separated from antidiquarks. With the same method we confirm that doubly heavy tetraquarks are stable against strong decays. Tetraquarks described here provide a new picture of exotic hadrons, as formed by the QCD analog of the hydrogen bond of molecular physics.

Unifying structures in quantum integrable systems

Year: 1997
Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: FOS: Physical sciences

description: Basic concepts of quantum integrable systems (QIS) are presented stressing on the unifying structures underlying such diverse models. Variety of ultralocal and nonultralocal models is shown to be described by a few basic relations defining novel algebraic entries. Such properties can generate and classify integrable models systematically and also help to solve exactly their eigenvalue problem in an almost model-independent way. The unifying thread stretches also beyond the QIS to establish its deep connections with statistical models, conformal field theory etc. as well as with abstract mathematical objects like quantum group, braided or quadratic algebra

description: A model is proposed to study the hybrid exciton in a quantum dot-dendrimer systems. The semiconductor organic hybrid exciton is studied using a "real space" Green's function method and a diagrammatic technique. The energy of the hybrid exciton as well as the Green function matrix elements have been calculated for different quantum dot-dendrimer systems, and the method can be applied for systems with different structures. Using the double-time Green's functions the optical processes can be calculated. The optical properties of the systems are controllable by the size and structure of the QD-dendrimer systems.

The Impact of the Railway on Uckfield in the 19th Century
Creators: name: Pearce, Sally A
Publisher: name: Archaeology Data Service

description: Sussex Archaeological Collections, 122, 193-206
description: Uckfield was a small Sussex town at the beginning of the 19th century and was brought out of rural isolation in 1858 when the rail link with Lewes was opened; it was later extended to Tunbridge Wells. This study considers the part played by the railway in the development of Uckfield during the 19th century. Uckfield and its people are analysed to identify the trading and settlement patterns influenced by existing modes of transport in the 1840s, predating the railway. Attention is then drawn to changes in the community after 1858 initiated by the new form of transport. The major part of the discussion concerns the development of Uckfield to the end of the 19th century with reference to the social, economic and topographical changes brought about, at least in part, by the railway.

Atrial fibrillation--Treatment
Near infrared spectroscopy
Catheter ablation

description: Patients with atrial fibrillation (AF) require modification of ectopic electrical activity to avoid potentially fatal health complications. Catheter ablation therapy is a minimally invasive procedure to create tissue necrosis, called lesion, in areas of abnormal electrical activity. However, significant proportion of patients require repeat treatment from AF recurrences in part by electrical reconnection from incomplete lesions and conduction recovery. Current therapeutic approaches are limited by reliable methods to assess AF structural substrates and validate lesion sufficiency during procedures. In recent years, development of near-infrared optical spectroscopy has provided a non-invasive method to evaluate biological tissue. Near infrared spectroscopy (NIRS) is an optical technique that enables direct characterization of pathological tissue based on the absorption of major chromophores and light scattering. In this thesis, we explore the use of near-infrared optical spectroscopy to identify AF substrates and quantify lesion formation to improve treatment efficacy. First, we developed a near-infrared multispectral imaging system and present a model to assess lesion adequacy by direct visualization of cardiac lesions through an endoscope-integrated probe. Then, a custom single fiber integrated radiofrequency (RF) ablation catheter was fabricated to track irrigated lesion progression real-time on ex vivo swine hearts. A machine learning model was introduced to predict lesion size and transmurality. Additionally, we assess the feasibility of near-infrared spectroscopy by fabricating a NIRS-integrated open-irrigation RF ablation catheter and an algorithm to assess lesion dimensions based on key features derived from NIRS measurements. Using this model, we demonstrate real-time tracking of irrigated lesion delivery in both ex vivo and in vivo swine model. Lastly, we show left atrial endocardial mapping with NIRS-integrated RF mapping catheter to assess AF structural substrates. We present a classification algorithm for important AF structural substrates, such as pulmonary vein sleeve, normal myocardium, ablated tissue, and fibrosis, and a regression model to validate lesion adequacy. A near-infrared spectroscopy-based techniques to localize structural complexities and validate lesion sufficiency at the catheter tip could enhance the understanding of underlying AF substrates and improve treatment efficacy.

description: In this work, we consider nonnegative matrix factorization (NMF) with a regularization that promotes small volume of the convex hull spanned by the basis matrix. We present highly efficient algorithms for three different volume regularizers, and compare them on endmember recovery in hyperspectral unmixing. The NMF algorithms developed in this work are shown to outperform the state-of-the-art volume-regularized NMF methods, and produce meaningful decompositions on real-world hyperspectral images in situations where endmembers are highly mixed (no pure pixels). Furthermore, our extensive numerical experiments show that when the data is highly separable, meaning that there are data points close to the true endmembers, and there are a few endmembers, the regularizer based on the determinant of the Gramian produces the best results in most cases. For data that is less separable and/or contains more endmembers, the regularizer based on the logarithm of the determinant of the Gramian performs best in general.
