description: Streamflow records in many regions of Eurasia including South Asia are short and fragmentary. This makes it challenging to contextualise natural climate variability relative to anthropogenic climate change and evaluate the severity of recent extreme events. In the first section of the dissertation (Chapter 1 and 2) we use tree rings to reconstruct centennial-scale streamflow of the Indus and Brahmaputra Rivers in South Asia for the past six centuries. These two rivers and their tributaries are fed by Himalayan glaciers and the South Asian Monsoon and are the basis of economic, social, and cultural life of over 700 million people in the region. These centennial reconstructions of past discharge provide valuable information about long-term hydroclimate variability, drought and flood hazard. They also help us to interpret recent climate extremes relative to those in the past and benchmark projections of climate change for the region. Large tropical (and extratropical) volcanic eruptions can release large quantities of reflective sulphate aerosols into the stratosphere where they may persist for up to 3 years. In Chapter 3 we discuss how these aerosols can impact European and Mediterranean hydroclimate by causing dry conditions over northwestern Europe and the British Isles and wet conditions over the western Mediterranean. We examine this hydroclimate response using Superposed Epoch Analysis (SEA), a statistical method used to identify consistent responses to events by testing for the possibility of random occurrence. Finally, in Chapter 4 we describe in further detail (cf. Chapter 3) the modified double-bootstrap SEA that we developed in Chapter 3 to examine the uncertainty inherent in SEA within a probabilistic framework. We describe our modified SEA by applying it to two datasets, a reconstruction of northern hemisphere summer temperature for the past millennium, and a compilation of tree ring fire scar records for the western U.S. Using these two datasets we examine post-eruption northern hemisphere cooling following volcanism and the synchrony between drought conditions and fire events in the western U.S. respectively.
Hybrid System Combination for Machine Translation: An Integration of Phrase-level and Sentences-level Combination Approaches

Subjects: Computer science

description: Given the wide range of successful statistical MT approaches that have emerged recently, it would be beneficial to take advantage of their individual strengths and avoid their individual weaknesses. Multi-Engine Machine Translation (MEMT) attempts to do so by either fusing the output of multiple translation engines or selecting the best translation among them, aiming to improve the overall translation quality. In this thesis, we propose to use the phrase or the sentence as our combination unit instead of the word; three new phrase-level models and one sentence-level model with novel features are proposed. This contrasts with the most popular system combination technique to date which relies on word-level confusion network decoding.
        Among the three new phrase-level models, the first one utilizes source sentences and target translation hypotheses to learn hierarchical phrases -- phrases that contain subphrases (Chiang 2007). It then re-decodes the source sentences using the hierarchical phrases to combine the results of multiple MT systems. The other two models we propose view combination as a paraphrasing process and use paraphrasing rules. The paraphrasing rules are composed of either string-to-string paraphrases or hierarchical paraphrases, learned from monolingual word alignments between a selected best translation hypothesis and other hypotheses. Our experimental results show that all of the three phrase-level models give superior performance in BLEU compared with the best single translation engine. The two paraphrasing models outperform the re-decoding model and the confusion network baseline model.
        The sentence-level model exploits more complex syntactic and semantic information than the phrase-level models. It uses consensus, argument alignment, a supertag-based structural language model and a syntactic error detector. We use our sentence-level model in two ways: the first selects a translated sentence from multiple MT systems as the best translation to serve as a backbone for paraphrasing process; the second makes the final decision among all fused translations generated by the phrase-level models and all translated sentences of multiple MT systems. We proposed two novel hybrid combination structures for the integration of phrase-level and sentence-level combination frameworks in order to utilize the advantages of both frameworks and provide a more diverse set of plausible fused translations to consider.

description: Let $g$ be a bounded symmetric measurable nonnegative function on $[0,1]^2$, and $\left\lVert g \right\rVert = \int_{[0,1]^2} g(x,y) dx dy$. For a graph $G$ with vertices $\{v_1,v_2,\ldots,v_n\}$ and edge set $E(G)$, we define \[ t(G,g) \; = \; \int_{[0,1]^n} \prod_{\{v_i,v_j\} \in E(G)} g(x_i,x_j) \: dx_1 dx_2 \cdots dx_n \; . \] We conjecture that $t(G,g) \geq \left\lVert g \right\rVert^{|E(G)|}$ holds for any graph $G$ and any function $g$ with nonnegative spectrum. We prove this conjecture for various graphs $G$, including complete graphs, unicyclic and bicyclic graphs, as well as graphs with $5$ vertices or less.

description: We present a method to solve initial and boundary value problems using artificial neural networks. A trial solution of the differential equation is written as a sum of two parts. The first part satisfies the boundary (or initial) conditions and contains no adjustable parameters. The second part is constructed so as not to affect the boundary conditions. This part involves a feedforward neural network, containing adjustable parameters (the weights). Hence by construction the boundary conditions are satisfied and the network is trained to satisfy the differential equation. The applicability of this approach ranges from single ODE's, to systems of coupled ODE's and also to PDE's. In this article we illustrate the method by solving a variety of model problems and present comparisons with finite elements for several cases of partial differential equations.

description: Van der Waals materials and inorganic nanoparticles are two categories of nanomaterials that have been widely investigated in the past two decades. Both of them have been considered to be promising as candidates for the next generation electrical, optical, and mechanical applications. However, both of them have a few limitations that greatly affect the performance of devices, e.g. zero bandgap for graphene; poor contact quality, low mobility and quantum efficiency for MoS2; and poor interparticle conductivity for nanoparticles. This thesis tries to explore a new way of combining these two categories of material into hybrids, so that the intrinsic limitations of materials from each category will be overcome by the other materials that are introduced into the hybrid.
      This thesis consists of five parts. The first part (Chapter 1) introduces the background and motivation of the thesis. The second part (Chapters 2, 3, 4, and 5) describes the detailed processes and methods, starting from preparing each element to the assembly of these element into a hybrid structure device. This part also includes understanding the mechanisms of 2D and 3D self-assembly of nanoparticles. The third part (Chapter 6 and 7) describes two examples of hybrid structures, including the investigation of electron or molecule transfer inside the hybrid. The fourth part (Chapter 8) introduces other findings and technical innovations, including alternative ways of thin film nanoparticle self-assembly/deposition, and fabrication methods for the band structure analysis of transition metal dichalcogenides by angle resolved photo-electron spectroscopy. The fifth part (Chapter 9) describes several possible future work directions that could be investigated to improve the understanding of the nanoparticle assembly and translating the conceptual device into real applications.

description: Let $p(n)$ denote the smallest prime divisor of the integer $n$. Define the function $g(k)$ to be the smallest integer $>k+1$ such that $p(\binom{g(k)}{k})>k$. So we have $g(2)=6$ and $g(3)=g(4)=7$. In this paper we present the following new results on the Erdős-Selfridge function $g(k)$: We present a new algorithm to compute the value of $g(k)$, and use it to both verify previous work and compute new values of $g(k)$, with our current limit being $$ g(323)= 1\ 69829\ 77104\ 46041\ 21145\ 63251\ 22499. $$ We define a new function $\hat{g}(k)$, and under the assumption of our Uniform Distribution Heuristic we show that $$ \log g(k) = \log \hat{g}(k) + O(\log k) $$ with high "probability". We also provide computational evidence to support our claim that $\hat{g}(k)$ estimates $g(k)$ reasonably well in practice. There are several open conjectures on the behavior of $g(k)$ which we are able to prove for $\hat{g}(k)$, namely that $$ 0.525\ldots +o(1) \quad \le \quad \frac{\log \hat{g}(k)}{k/\log k} \quad \le \quad 1+o(1), $$ and that $$ \limsup_{k\rightarrow\infty} \frac{\hat{g}(k+1)}{\hat{g}(k)}=\infty.$$ Let $G(x,k)$ count the number of integers $n\le x$ such that $p(\binom{n}{k})>k$. Unconditionally, we prove that for large $x$, $G(x,k)$ is asymptotic to $x/\hat{g}(k)$. And finally, we show that the running time of our new algorithm is at most $g(k) \exp[ -c (k\log\log k) /(\log k)^2 (1+o(1))]$ for a constant $c>0$.

description: Urban community gardens (UCGs) are receiving greater attention as an ever-growing body of research documents the economic, environmental and social benefits that community gardens are bringing to urban neighborhoods. However, land insecurity remains one of the critical barriers to the future success of UCGs; loss of land to both private and public entities has frustrated many efforts and has stimulated investigations into alternative strategies for increasing land security. This thesis explores the diversity of land tenure solutions -- with a particular respect to land trusts -- that have been implemented to address this issue. Land security is objectively defined by legal property rights and subjectively shaped through the notion of 'ownership in use' and by encouraging the formation of mobilized communities. We analyze the variety of organizational modes -- differentiated by tenurial arrangement, organizational capacity, political leverage and organizational mission/internal governance relations -- and the resulting impacts on the type and level of land security. Data was collected through transcribed interviews with practitioners from sixteen land trust organizations engaged in urban community gardening and summarized along emergent themes regarding organizational modes and resulting land security implications. We find that major tradeoffs exist between maximizing land tenure security and operating a larger number of UCG sites under less secure tenure arrangements. It concludes that underutilized opportunities exist to increase UCG land security through an increased public sector role and broader cross-sectoral partnerships.

Social Approach of Ziauddin Barani in Official Historiography

Subjects: History

description: In narrations of old history, official history has an important place, as it narrates the history of governments or their desires. There are various works with this approach; meanwhile people are given a place in some official historiographies. Ziauddin Barani is one of the historians who reports social problems alongside official history Delhi Sultanate.
This article, using descriptive analytic method on direct and indirect mentions, explores this hypothesis that Barani, besides writing the official history of Tughlaq dynasty has pictured the situation of citizenry. This way he has started a new type of historiography in which the focus is changing from government to people.
The results show that his work is inclined to social history an Barani has not neglected the role of people in government's strengths and weaknesses. He had serious notation to social problems to guide the governors to reform in society, and his cause and effect search in social and economic occurrences could be a sign of his analysis from effective factors in social changes.

description: Directly imaging exoplanets is challenging because quasi-static phase aberrations in the pupil plane (speckles) can mimic the signal of a companion at small angular separations. Kernel phase, which is a generalization of closure phase (known from sparse aperture masking), is independent of pupil plane phase noise to second order and allows for a robust calibration of full pupil, extreme adaptive optics observations. We applied kernel phase combined with a principal component based calibration process to a suitable but not optimal, high cadence, pupil stabilized L' band ($3.8~μ\text{m}$) data set from the ESO archive. We detect eight low-mass companions, five of which were previously unknown, and two have angular separations of $\sim0.8$-$1.2~λ/D$ (i.e. $\sim80$-$110~\text{mas}$), demonstrating that kernel phase achieves a resolution below the classical diffraction limit of a telescope. While we reach a $5σ$ contrast limit of $\sim1/100$ at such angular separations, we demonstrate that an optimized observing strategy with more diversity of PSF references (e.g. star-hopping sequences) would have led to a better calibration and even better performance. As such, kernel phase is a promising technique for achieving the best possible resolution with future space-based telescopes (e.g. JWST), which are limited by the mirror size rather than atmospheric turbulence, and with a dedicated calibration process also for extreme adaptive optics facilities from the ground.

description: We investigate the spectrum of quasiparticle excitations in the core of isolated pancake vortices in clean layered superconductors. Analysis of the spectral current density shows that both the circular current around the vortex center as well as any transport current through the vortex core is carried by localized states bound to the core by Andreev scattering. Hence the physical properties of the core are governed in clean high-$κ$ superconductors (e.g. the cuprate superconductors) by the Andreev bound states, and not by normal electrons as it is the case for traditional (dirty) high-$κ$ superconductors.

description: We consider deformations of finite or infinite dimensional Lie algebras over a field of characteristic 0. There is substantial confusion in the literature if one tries to describe all the non-equivalent deformations of a given Lie algebra. It is known that there is in general no "universal" deformation of the Lie algebra L with a commutative algebra base A with the property that for any other deformation of L with base B there exists a unique homomorphism f: A -> B that induces an equivalent deformation. Thus one is led to seek a "miniversal" deformation. For a miniversal deformation such a homomorphism exists, but is unique only at the first level. If we consider deformations with base spec A, where A is a local algebra, then under some minor restrictions there exists a miniversal element. In this paper we give a construction of a miniversal deformation.

description: The present paper is the companion of [1] in which we proposed a scheme that tries to derive the Quantum Field Theory (QFT) on Curved Spacetimes (CST) limit from background independent Quantum General Relativity (QGR). The constructions of [1] make heavy use of the notion of semiclassical states for QGR. In the present paper, we employ the complexifier coherent states for QGR recently proposed by Thiemann and Winkler as semiclassical states, and thus fill the general formulas obtained in [1] with life. We demonstrate how one can, under some simplifying assumptions, explicitely compute expectation values of the operators relevant for the gravity-matter Hamiltonians of [1] in the complexifier coherent states. These expectation values give rise to effective matter Hamiltonians on the background on which the gravitational coherent state is peaked and thus induce approximate notions of n-particle states and matter propagation on fluctuating spacetimes. We display the details for the scalar and the electromagnetic field. The effective theories exhibit two types of corrections as compared to the the ordinary QFT on CST. The first is due to the quantum fluctuations of the gravitational field, the second arises from the fact that background independence forces both geometry and matter to propagate on a spacetime that is the product of the real line and a (random) graph. Finally we obtain explicit numerical predictions for non-standard dispersion relations for the scalar and the electromagnetic field. They should, however, not be taken too seriously, due to the many ambiguities in our scheme, the analysis of the physical significance of which has only begun. We show however, that one can classify these ambiguities at least in broad terms.

description: A rate equation model describing the laser dynamics of general one or two dimensional vertical cavity surface emitting laser (vcsel) arrays is introduced. It is shown that the theory includes both the previous theory for edge emitting semiconductor laser arrays and the theory of polarization dynamics in single quantum well vcsels in a single unified description. The model is based on the physical assumption of separate carrier density pools individually coupled to different light field modes. These modes interact through the coherent light field dynamics derived from Maxwell's equations. The special case of two densities and two light field modes is solved and the implications for larger arrays are discussed. Our analytic results show that typical solutions of the split density model range from phase locking to chaos, depending on the magnitude of the coherent interaction. For weak coupling the stable supermode is always the mode of highest frequency. This indicates that anti-phase locking is the only stable phase locking possible in semiconductor laser arrays.

description: This is a study of teacher pushout among Black male educators. In particular, this study examines experiences that prompted Black male teachers to resign or be terminated from teaching positions with the goal of exploring contributing factors to Black male teacher turnover. Drawing from the pushout stories of 9 Black male educators, this study found that Black male teachers experienced pushout in three phases: 1) the Reason – characterized by idealistic and hopeful feelings about being a change agent in the lives of students, 2) the Reality – characterized by various turning points that made it clear that the teaching positions these teachers were in might be less than ideal, and 3) the Removal – characterized by a steady escalation of negative events and interactions that eventually led to their pushout (through firing or resignation). Within these phases, several themes emerged. During the Reason phase, participants reported feeling a sense of responsibility to teach and mentor disadvantaged students – particularly Black males, love for teaching, and a sense of calling to teach. The Reality phase was characterized by pressure to conform to the expectation of masculinity suppression or over-expression depending on the needs and desires of co-workers and administration, limitations on creativity, and pressure to go along with policies and practices that participants felt were unethical or ineffective. Finally, the Removal phase was characterized by a culmination event that resulted in a move to another school or out of the field of education entirely. This dissertation builds on research about teacher turnover and identifies teacher pushout, a specific phenomenon within teacher turnover. Further, this study examines pushout among Black males.

description: We study a quantum Ising chain with tailored bulk dissipation, which can be mapped onto a non-Hermitian Ashkin-Teller model. By exploiting the Kohmoto-den Nijs-Kadanoff transformation, we further map it to a staggered XXZ spin chain with pure-imaginary anisotropy parameters. This allows us to study the eigenstates of the original Liouvillian in great detail. We show that the steady state in each parity sector is a completely mixed state. The uniqueness of each is proved rigorously. We then study the decay modes on the self-dual line corresponding to the uniform XXZ chain and obtain an exact formula for the Liouvillian gap $ g $, the inverse relaxation time, in the thermodynamic limit. The gap $ g $ as a function of dissipation strength $ Δ$ has a cusp, implying a kind of phase transition for the first decay mode.

description: In this paper we study the auxiliary problems that appear in $p$-order tensor methods for unconstrained minimization of convex functions with $ν$-Hölder continuous $p$th derivatives. This type of auxiliary problems corresponds to the minimization of a $(p+ν)$-order regularization of the $p$th order Taylor approximation of the objective. For the case $p=3$, we consider the use of Gradient Methods with Bregman distance. When the regularization parameter is sufficiently large, we prove that the referred methods take at most $\mathcal{O}(\log(ε^{-1}))$ iterations to find either a suitable approximate stationary point of the tensor model or an $ε$-approximate stationary point of the original objective function.

description: We demonstrate rigorously that in the absence of explicit spin-dependent forces one of the ground states of interacting bosons with spin is always fully polarized -- however complicated the many-body interaction potential might be. Depending on the particle spin, the polarized ground state will generally be degenerate with other states, but one can specify the exact degeneracy. For T>0 the magnetization and susceptibility necessarily exceed that of a pure paramagnet. These results are relevant to recent experiments exploring the relation between triplet superconductivity and ferromagnetism, and the Bose-Einstein condensation of atoms with spin. They eliminate the possibility, raised in some theoretical speculations, that the ground state or positive temperature state might be antiferromagnetic.

description: Everyone is a moon - a beautiful bright ball isolated in the sky. But as you come closer, the craters appear. Voyeurism, sexual passion, jealousy, and the ever present search for connection and love. Following the stories of six characters as they navigate the complexities of their longings, the play weaves a poetic and darkly humorous journey into the beauty of our ugly side.

description: This paper shows how job search success, measured as search duration and entry salary, is affected directly or indirectly by personal and process as well as structural characteristics. A specific focus is on the relevance of practical experience which is claimed to be a key feature of employability. While self‐assessed practical and namely international experience is positively related to salary, but not to search duration, the number and duration of internships does not affect job search success. Results are relevant for higher education institutions to develop their curricula, for students to prepare for job search, and for employers to understand the genesis of employability and their potential means to impact it.
Tensor Methods for Finding Approximate Stationary Points of Convex Functions

description: In this paper we consider the problem of finding $ε$-approximate stationary points of convex functions that are $p$-times differentiable with $ν$-Hölder continuous $p$th derivatives. We present tensor methods with and without acceleration. Specifically, we show that the non-accelerated schemes take at most $\mathcal{O}\left(ε^{-1/(p+ν-1)}\right)$ iterations to reduce the norm of the gradient of the objective below a given $ε\in (0,1)$. For accelerated tensor schemes we establish improved complexity bounds of $\mathcal{O}\left(ε^{-(p+ν)/[(p+ν-1)(p+ν+1)]}\right)$ and $\mathcal{O}\left(|\log(ε)|ε^{-1/(p+ν)}\right)$, when the Hölder parameter $ν\in [0,1]$ is known. For the case in which $ν$ is unknown, we obtain a bound of $\mathcal{O}\left(ε^{-(p+1)/[(p+ν-1)(p+2)]}\right)$ for a universal accelerated scheme. Finally, we also obtain a lower complexity bound of $\mathcal{O}\left(ε^{-2/[3(p+ν)-2]}\right)$ for finding $ε$-approximate stationary points using $p$-order tensor methods.

I. Advanced Fluorescent False Neurotransmitters for the Study of Monoamine Transporter Activity and Synaptic Transmission
Creators: Karpowicz, Richard
Publisher: name: Columbia University
Year: 2013
Subjects: subject: Chemistry
subject: Neurosciences
subject: FOS: Clinical medicine

description: This thesis details two projects at the interface of chemistry and neuroscience.  Part I focuses on the development and characterization of fluorescent optical tracers of monoamine neurotransmitters for use in the study of monoamine transporter activity and distribution, as well as synaptic transmission in the brain.  The second section details early studies concerning experimental therapeutics recently identified by our group to induce the synthesis and release of Glial Derived Neurotrophic Factor (GDNF) from a model astroglial cell line. Part I consists of Chapters 1-5.  Chapter 1 provides a brief introduction to the relationship between chemistry and neuroscience, while explaining the motivation and background behind the development and study of Fluorescent False Neurotransmitters (FFNs).  Chapter 2 discusses the characterization of new fluorescent substrates for the Vesicular Monoamine Transporter 2 (VMAT2) for applications in high throughput screening of VMAT activity and inhibition, as well as for imaging aminergic synaptic transmission in brain tissue. Chapter 3 describes the discovery of fluorescent probes FFN201 and AGH093 as dual substrates for the norepinephrine transporter (NET) and VMAT, with potential applications in the imaging of noradrenergic modulation of cortical signaling networks. NG54, a FFN with substrate activity at each of the monoamine transporters was also identified, and represents a new structural class of FFNs.  In Chapter 4, APP+, a known fluorescent substrate for the monoamine transporters, is evaluated as a potential tracer of monoamines in the brain.  It has been determined that while this molecule may have utility as a marker for monoaminergic neurons, APP+ is not an appropriate FFN due to high background labeling of mitochondria and other intracellular structures.  Chapter 5 discusses the discovery of fluorescent substrates of the Organic Cation Transporter 3 (OCT3) and Plasma Membrane Monoamine Transporter (PMAT). Mounting evidence suggests that these transporters play a significant role in clearing extracellular space of monoamines and are likely involved in neurological disease.  As such, fluorescent substrates of OCT3 or PMAT would be useful as imaging agents in the brain, as well as for the development of fluorescence-based quantitative inhibition assays. Part II of this thesis (Chapter 6) discusses N-arylethyl isoquinuclidines as releasers of glial cell line-derived neurotrophic factor (GDNF) from a model glial cell line.  Initial characterization of GDNF release and its dependence on protein synthesis and MAPK/ERK signaling is described.  Preliminary studies indicate that at least two experimental compounds described herein modulate fibroblast growth factor receptor (FGFR) signaling.
Magnetoelectric Response in Electric Octupole State: Possible Hidden Order in Cuprate Superconductors

description: Motivated by recent studies of odd-parity multipole order in condensed matter physics, we theoretically study magnetoelectric responses in an electric octupole state. Investigating the Edelstein effect and spin Hall effect in a locally noncentrosymmetric bilayer Rashba model, we clarify characteristic properties due to parity violation in the electric octupole state. Furthermore, a possible realization of electric octupole order in bilayer high-Tc cuprate superconductors is proposed. Our calculation of magnetic torque is consistent with recent experimental observation of a kink above the superconducting transition temperature. We also show significant enhancement of the in-plane anisotropy in spin susceptibility due to the superconductivity, and propose an experimental test by means of the nuclear magnetic resonance in the superconducting state. A spin-orbit coupled metal state in Cd2Re2O7 is also discussed.

 COMMENTS: Both, S. banonense and S. obscuricolle were transferred to Pseudobironium by Löbl, 1970: 126. Each was represented in the MNHN collection by a single specimen that was incorrectly assumed to be the holotype of the respective species (Löbl, 1970: 126). In fact, these specimens are lectotypes (ICZN, Art. 74.6), designated in that latter paper. The names were synonymized, the aedeagus illustrated, and additional distributional records were given in Löbl (2011a: 308).
