description: The main objective of the paper, the first paper in a dedicated series, is to report basic results on systematic research of low-redshift optically selected SDSS Type-2 AGN but with apparent optical variabilities. For all the pipeline classified Type-2 AGN in SDSS DR16 with $z<0.3$ and $SN>10$, long-term optical V-band light curves are collected from Catalina Sky Survey. Through all light curves described by Damped Random Walk process with process parameters of $σ/(mag/days^{0.5})$ and $τ/days$, 156 Type-2 AGN have apparent variabilities with process parameters at least three times larger than corresponding uncertainties and with $\ln(σ/(mag/days^{0.5}))>-4$, indicating central AGN activity regions directly in line-of-sight, leading the 156 Type-2 AGN as mis-classified Type-2 AGN. Furthermore, based on spectroscopic emission features around H$α$, 31 out of the 156 AGN have broad H$α$, indicating the 31 Type-2 AGN are actually Type-1.8/1.9 AGN. Meanwhile, 14 out of the 156 AGN have multi-epoch SDSS spectra. After checking multi-epoch spectra of the 14 objects, no clues for appearance/disappearance of broad lines indicate true Type-2 AGN rather than changing-look AGN are preferred in the collected Type-2 AGN with long-term variabilities. Moreover, a small sample of Type-2 AGN have long-term variabilities with features roughly described by theoretical TDEs expected $t^{-5/3}$, indicating probable central TDEs as further and strong evidence to support true Type-2 AGN.

description: Integrated pest management (IPM) has been promoted globally as an alternative approach to the widespread broad-spectrum chemical insecticidal application for the control of pests and diseases in agricultural production to minimise the harmful effects of the chemicals on humans and the environment. This study examines the impact of an IPM strategy developed to control mango fruit flies on humans and the environment. Using a random sample of 371 mango farmers from Meru County in Kenya, health and environmental outcomes were measured using the environmental impact quotient (EIQ) field use and causal impacts, which were estimated using the endogenous switching regression (ESR) model. The results indicate that the adoption of the IPM strategy reduced pesticide use and pesticide toxicity. Policy efforts therefore should focus on promoting and disseminating fruit fly IPM to improve the livelihoods of rural mango farmers, but also reduce human health and environmental threats as a result of pesticide use

description: In this article, two results regarding the Moore-Penrose inverse in the frame of $C^*$-algebras are considered. In first place, a characterization of the so-called reverse order law is given, which provides a solution of a problem posed by M. Mbekhta. On the other hand, Moore-Penrose hermitian elements, that is $C^*$-algebra elements which coincide with their Moore-Penrose inverse, are introduced and studied. In fact,these elements will be fully characterized both in the Hilbert space and in the $C^*$-algebra setting. Furthermore, it will be proved that an element is normal and Moore-Penrose hermitian if and only if it is a hermitian partial isometry.

description: Analogue gravity succeeded to simulate Hawking radiation and test it in laboratories. In this setting, the black hole is simulated by an area in a fluid, say water, where no sound wave can escape the event horizon and phonon oscillations are detected as Hawking radiation. This means that the analogue simulations can provide an alternative description, and consequently, a new insight to the high energy physics problems. Now it would be interesting to see what information loss means and how island prescription is interpreted in water experiment. In this paper we show that the analogue of information loss is the loss of momentum per unit mass of the fluid over the horizon and maintaining the momentum loss leads to the island prescription.

description: Agricultural commercialisation is a critical pathway for economic development in Sub-Saharan Africa (SSA). However, the lack of market information may impede this development. To the best of the authors’ knowledge, this is the first paper to examine market information and preferences for soybean quality in a developing-world context. We seek to understand the nature of information markets associated with the nascent soybean trade in Sub-Saharan Africa in order to inform the market and policy of previously unknown key marketing information. The research involves a discrete choice experiment with 228 buyers of soybean involving five key soybean quality attributes. The sample represents three distinct classes of buyer/traders: wholesalers, processors and retailers. Traders significantly discount the price of soybean attributes such as off-colour, small grain size, low oil levels and high contamination with foreign material, such as stones. Foreign material ranks highest of the attributes that we examined, in terms of the discount level, at 22%. The study finds significant preference heterogeneity among traders, explained partly by the socioeconomic and trade characteristics of the respondents. We identified three distinct classes of traders per the latent class logit (LCL) results, namely ‘high price discounters’, ‘big bean supporters’, and ‘oil sceptics’. Our findings improve soybean market information, transparency and signalling. This will lead farmers to be more efficient and allow policymakers to understand better how the market actually prices grain at the farm gate.

description: We investigate the origin of the translational symmetry breaking in epitaxially grown single-layer graphene. Despite the surface morphology of homogeneous graphene films influenced by the presence of mutually parallel SiC surface terraces, the far-infrared magneto-plasmon absorption is almost independent of the angle between the probing light polarization and the orientation of terraces. Based on a detailed analysis of the plasmon absorption lineshape and its behavior in the magnetic field, supported by confocal Raman mapping and atomic force microscopy, we explain this discrepancy by spontaneously formed graphene micro flakes. We further support our conclusions using data collected on artificially created graphene nanoribbons: we recognize similar plasmon origin in artificial ribbons and naturally formed grains. An unexpectedly large plasmon resonance redshift was observed in nanoribbons. In a hydrogen-intercalated sample (which does not contain the buffer), this redshift is quantitatively taken into account by a plasmon-plasmon interaction. In non-intercalated samples featuring a buffer layer, this redshift is due to an interplay between the plasmon-plasmon coupling and Coulomb screening by the buffer-induced interface states. This model determines the density of interface states in good agreement with experimentally reported values.

Nanocrystals

description: Localized surface plasmon resonance (LSPR) in semiconductor nanocrystals (NCs) that results in resonant absorption, scattering, and near field enhancement around the NC can be tuned across a wide optical spectral range from visible to far-infrared by synthetically varying doping level. Cube-shaped NCs of conventional metals like gold and silver generally exhibit LSPR in the visible region with spectral modes determined by their faceted shapes. However, faceted NCs exhibiting LSPR response in the infrared (IR) region are relatively rare. We describe the colloidal synthesis of nanoscale fluorine-doped indium oxide (F:In₂O₃) cubes with LSPR response in the IR region, wherein fluorine was found to both direct the cubic morphology and act as an aliovalent dopant. The presence of fluorine was found to impart higher stabilization to the (100) facets, suggesting that the cubic morphology results from surface binding of F-atoms. In addition, fluorine acts as an anionic aliovalent dopant in the cubic bixbyite lattice of In₂O₃, introducing a high concentration of free electrons leading to LSPR. The cubes exhibit narrow, shape-dependent multimodal LSPR extinction peaks due to corner- and edge-centered modes. The spatial origin of these different contributions to the spectral response are directly visualized by electron energy loss spectroscopy (EELS) in a scanning transmission electron microscope (STEM). A synthetic challenge in faceted metal oxide NCs is realizing tunable LSPR near-field response in the IR. We expand to colloidal synthesis of fluorine, tin co-doped indium oxide (F,Sn:In₂O₃) NC cubes with tunable IR range LSPR. Free carrier concentration is tuned through controlled Sn dopant incorporation, where Sn is an aliovalent n-type dopant in the In₂O₃ lattice. Monolayer NC arrays are fabricated through liquid-air interface assembly, NC film nanocavities with heightened near-field enhancement (NFE). The tunable F,Sn:In₂O₃ NC near-field is coupled with PbS quantum dots, via the Purcell effect. The detuning frequency between the nanocavity and exciton is varied, resulting in IR near-field dependent enhanced exciton lifetime decay
Angular analysis of the B0 to K*0μ+μ- decay at the LHCb experiment
Creators: name: Kress, Felix Johannes
Publisher: name: Imperial College London
Year: 2020

description: An angular analysis of the B0 → K*0 (→ K+μ-) μ+μ- decay is presented in this thesis. The measurement uses a data set corresponding to an integrated luminosity of 4.7fb-1 of pp collision data collected with the LHCb detector during the years 2011, 2012 and 2016. Angular observables are determined in bins of the invariant dimuon mass squared using an unbinned maximum likelihood fit, in which contamination from decays with the K+μ- system in an S-wave configuration is taken into account. The results of the observables are the most precise to date, reducing the uncertainty with respect to the previous LHCb measurements by approximately 30%. The tension that was previously observed with the Standard Model predictions persists, and studies with the FLAVIO software package indicate a slight increase in the tension. However, the precise value depends on the choice of theory nuisance parameters.

A High Order Cartesian Grid, Finite Volume Method for Elliptic Interface Problems

description: We present a higher-order finite volume method for solving elliptic PDEs with jump conditions on interfaces embedded in a 2D Cartesian grid. Second, fourth, and sixth order accuracy is demonstrated on a variety of tests including problems with high-contrast and spatially varying coefficients, large discontinuities in the source term, and complex interface geometries. We include a generalized truncation error analysis based on cell-centered Taylor series expansions, which then define stencils in terms of local discrete solution data and geometric information. In the process, we develop a simple method based on Green's theorem for computing exact geometric moments directly from an implicit function definition of the embedded interface. This approach produces stencils with a simple bilinear representation, where spatially-varying coefficients and jump conditions can be easily included and finite volume conservation can be enforced.

description: Honeybees are very sensitive to their breeding temperature. Even slightly lower temperatures during larval development can significantly affect adult behavior. Several devices which are employed for killing the honeybee ectoparasite Varroa destructor rely on short-term hyperthermia in the honeybee hive. The device used here applies 43.7 °C for 2 h, which is highly effective in killing the mites. We study how short-term hyperthermia affects worker brood and behavior of emerging adult bees. Sucrose responsiveness was strongly reduced after treatment of larvae early or late of larval development. Hyperthermia significantly enhanced life span, particularly in bees receiving treated early in larval development. To ask whether increased life span correlated with foraging performance, we used radio frequency identification (RFID). Onset and offset of foraging behavior as well as foraging trip duration and lifetime foraging effort were unaffected by hyperthermia treatment as prepupa.

description: We report on a systematic study of the ground-state octet baryon masses in the covariant baryon chiral perturbation theory with the extended-on-mass-shell renormalization scheme up to next-to-next-to-next-to-leading order, taking into account the contributions of the virtual decuplet baryons. A reasonable description of the lattice results is achieved by fitting simultaneously all the publicly available $n_f = 2+1$ lattice QCD data. It confirms that the various lattice simulations are consistent with each other. We stress that a self-consistent treatment of finite-volume corrections is important to obtain a $χ^2/\rm{d.o.f.}$ about 1.

description: In the context of loop quantum gravity, quantum states of geometry are mathematically defined as spin networks living on graphs embedded in the canonical space-like hypersurface. In the effort to study the renormalisation flow of loop gravity, a necessary step is to understand the coarse-graining of these states in order to describe their relevant structure at various scales. Using the spinor network formalism to describe the phase space of loop gravity on a given graph, we focus on a bounded (connected) region of the graph and coarse-grain it to a single vertex using a gauge-fixing procedure. We discuss the ambiguities in the gauge-fixing procedure and their consequences for coarse-graining spin(or) networks. This allows to define the boundary deformations of that region in a gauge-invariant fashion and to identify the area preserving deformations as U(N) transformations similarly to the already well-studied case of a single intertwiner. The novelty is that the closure constraint is now relaxed and the closure defect interpreted as a local measure of the curvature inside the coarse-grained region. It is nevertheless possible to cancel the closure defect by a Lorentz boost. We further identify a Lorentz-invariant observable related to the area and closure defect, which we name "rest area". Its physical meaning remains an open issue.

description: The definitions of global hyperbolicity for closed cone structures and topological preordered spaces are known to coincide. In this work we clarify the connection with definitions of global hyperbolicity proposed in recent literature on Lorentzian length spaces and Lorentzian optimal transport, suggesting possible corrections for the terminology adopted in these works. It is found that in Kunzinger-Sämann's Lorentzian length spaces the definition of global hyperbolicity coincides with that valid for closed cone structures and, more generally, for topological preordered spaces: the causal relation is a closed order and the causally convex hull operation preserves compactness. In particular, it is independent of the metric, chronological relation or Lorentzian distance.

description: The salicylidene Schiff bases of bis(2‐aminophenyl)diselenide and ‐ditelluride react with [MIICl2(PPh3)2] (M = Ni, Pt) or [PdII(OAc)2(PPh3)2] with formation of square‐planar complexes with the general formulae [MII(LY)(PPh3)] (M = Ni, Pd, Pt, Y = Se, Te). The ligands coordinate to the metals as tridentate {O,N,Se/Te} chelates. The reduction of the dichalcogenides and the formation of the chalcogenolato ligands occurs in situ by released PPh3 ligands. A mechanism for such reactions has been derived from the experimental data with the aid of DFT calculations. It suggests a higher polarization of the dichalcogenide bond with partial charge separation upon coordination to a metal centre, which therefore facilitates the cleavage of the dichalcogenide bond with PPh3. In accordance with the proposed mechanism, best yields are obtained with a strict exclusion of oxygen, but in the presence of water.

description: The main focus of this paper was to: (i) determine the impact of women’s share of household income on the pattern of expenditure on various categories of basic goods in southeast Nigeria; (ii) explain the pattern of household expenditure using the bargaining model of household behaviour; and (iii) extrapolate the results to the policy implications of gender-specific control of household incomes. We used cross-sectional household data elicited from a sample of 400 households constituting 2 520 members collected from November 2016 to March 2017 and disaggregated by gender. We found that increasing women’s share of incomes raises the budget share for food, children’s clothes, children’s school fees, fuel for household services and other expenditure, although not significantly with the budget shares for alcohol and meals out of the home. Our results suggest that any strategy by policymakers in southeast Nigeria to improve any of the expenditure items should target the empowerment of the gender that will more likely spend their money on the items concerned.

description: We investigate magnetotransport across an interface between two Weyl semimetals whose Weyl nodes project onto different interface momenta. Such an interface generically hosts Fermi arcs that connect Weyl nodes of identical chirality in different Weyl semimetals (homochiral connectivity) -- in contrast to surface Fermi arcs that connect opposite-chirality Weyl nodes within the same Weyl semimetal (heterochiral connectivity). We show that electron transport along the arcs with homochiral connectivity, in the presence of a longitudinal magnetic field, leads to a universal longitudinal magnetoconductance of $e^2/h$ per magnetic flux quantum. Furthermore, a weak tunnel coupling can result in a close encounter of two homochiral-connectivity Fermi arcs, enabling magnetic breakdown. Above the breakdown field the interface Fermi arc connectivity is effectively heterochiral, leading to a saturation of the conductance.

Однако существуют опасения относительно потенциальных осложнений, включая кровотечение и снижение функции почек. Ультразвуковая эластография является идеальным методом оценки изменений в различных органах и диагностики злокачественных опухолей. Этот метод может помочь обнаружить ранние изменения в функции почек и патологические изменения. Однако требуется осторожное применение и интерпретация этой методики в почках из-за ее сложной гемодинамики и архитектуры. Эластография сдвиговой волной является наиболее широко исследованным методом среди ультразвуковой эластографии.

description: An equation describing subdiffusion with possible immobilization of particles is derived by means of the continuous time random walk model. The equation contains a fractional time derivative of Riemann--Liouville type which is a differential-integral operator with the kernel defined by the Laplace transform. We propose the method for calculating the inverse Laplace transform providing the kernel in the time domain. In the long time limit the subdiffusion--immobilization process reaches a stationary state in which the probability density of a particle distribution is an exponential function.

description: The literature on broad-access colleges suggests that low persistence and completion rates may be improved through better advising that employs a teaching-as-advising approach. While resource constraints have traditionally limited the ability of colleges to reform advising practices, technological advances have made it possible to implement technology-based advising tools, some of which can replace face-to-face services. Using focus group interview data from 69 students at six colleges, this study investigates students’ attitudes toward technology-mediated advising. More specifically, the authors seek to understand how students’ perceptions and experiences vary across different advising functions. They find that students are open to using technology for more formulaic tasks, such as course registration, but prefer in-person support for more complex tasks, such as planning courses for multiple semesters and refining their academic and career goals.

description: We study Schrödinger operators on $\R$ with measures as potentials. Choosing a suitable subset of measures we can work with a dynamical system consisting of measures. We then relate properties of this dynamical system with spectral properties of the associated operators. The constant spectrum in the strictly ergodic case coincides with the union of the zeros of the Lyapunov exponent and the set of non-uniformities of the transfer matrices. This result enables us to prove Cantor spectra of zero Lebesgue measure for a large class of operator families, including many operator families generated by aperiodic subshifts.

description: Estimates of returns to equity capital invested in U.S. farm production are developed by using 1970 census benchmark data, which are the latest data available on farm finance. The rate of returns ranged from negative on farms with less than $10,000 gross farm sales to near 7 percent on the largest economic class farms. Only one-third of the farms had gross sales over $10,000, but accounted for 71 percent of all assets and earned returns above the composite average of 2.1 percent. This illustrates the problem inherent in using a composite average for "all farms" to represent the entire industry. The importance of off-farm income and additional returns to equity due to land appreciation probably explains why smaller farm units can exist on low farm returns. The difference in returns may help explain the increase in farm size, particularly for commercial units. Demands for loan funds will also substantially increase with the upward mobility in size classes and the tendency for larger farms to incur more debts. Higher capital requirements on larger units could also bring more equity financing in agriculture.

description: We present a cluster expansion EoS model for strongly-interacting matter based on the generalized Beth-Uhlenbeck formalism to describe hadrons as bound clusters of quarks. This formalism can describe both confined and deconfined phases. Our emphasis is on the region of vanishing baryon densities, where numerical solutions available from Lattice QCD predict a smooth crossover transition from hadron to quark matter. Medium effects are taken into account as self energies, which are motivated from both perturbative QCD calculations and phenomenological models. Parameters are tuned to Lattice QCD data and result in a good agreement of the thermodynamics.

description: Carbon nanotube (CNT) wires approach copper's specific conductivity and surpass carbon fiber's strength, with further improvement anticipated with greater aspect ratios and incorporation of dopants with long-range structural order. Fullerenes assemble into multitudes of process-dependent supramolecular crystals and, while initially insulating, they become marginally conductive (up to 0.05 MSm$^{-1}$) and superconductive ($T_c=18^\circ$K with K and 28$^\circ$K with Rb) after doping. These were small (100's $μ$m long), soft (hardness comparable to indium), and typically unaligned, which hindered development of fullerene based wires. Individual fullerenes were previously incorporated into CNT fibers, although randomly without self-assembly into supramolecules. Here, a simple variation in established CNT acid extrusion creates a fiber composed of uniaxial chains of aligned fullerene supramolecules, self-assembled between aligned few-walled CNT bundles. This will provide a testbed for novel fullerene wire transport and prospects in CNT wire advancement.

description: The adverse effects of weather extremes produce widespread damage and cause severe alterations in the normal functioning of household agricultural production in Zambia. Extreme weather events such as floods and drought are expected to increase in intensity and frequency due to climate change. Coupled with high poverty levels and limited institutional capacity, the country is highly vulnerable to the impact of extreme events. We quantify the effects of economic diversification on agricultural productivity of poor farm households with a skew-normal regression approach while accounting for drought and flood shocks. Our analysis finds that economic diversification is a strategy to increase agricultural productivity and mitigate the adverse impact of droughts and floods on agricultural households. The results also support the country's policies to encourage hybrid maize production and to provide crop seeds and fertiliser to poor farmers. This paper provides a framework to plan and inform interventions to enhance household economic resilience to weather shocks through agricultural diversification in Zambia and other countries.

description: Many community colleges offer a "student success" course—also known as College 101 or Introduction to College—as a means to help incoming students transition to college and become successful. The typical course is meant to provide key information and address important noncognitive skills and behavioral expectations with the goal of familiarizing students with the college environment and giving them the tools they need to build important competencies, persist in college, and earn a credential. This paper examines the efforts of Bronx Community College in implementing a redesigned student success course called First Year Seminar (FYS), which is intended to better support students than a typical student success course by incorporating academic content, skill-building exercises, and applied teaching pedagogies, among other features, into the course. Based on both qualitative and quantitative analysis, this study finds that FYS participation is associated with positive student outcomes that appear to be sustained for a longer period of time than what is typically found for students taking a traditional student success course. The focus of FYS on student-centered pedagogy and on integrated course content appears to be beneficial. The findings also suggest that when students have the opportunity to practice student success and basic academic skills within the context of an improved student success course, they are likely to apply those skills in future courses, potentially increasing their long-term educational attainment.

description: Mexican producers sharply expanded exports of fresh winter tomatoes, bell peppers, cucumbers, eggplants, and strawberries to U.S. markets during 1968-73. Comparatively low labor costs and climatic advantages stimulated this expansion. A hard freeze in Florida during the 1969/70 season added further stimulus to Mexico's expansion. But data for the 1974/75 season indicate a possible reversal of this trend, because Mexican exports were significantly reduced and Florida's shipments substantially increased. Factors affecting this possible trend reversal are sharply higher farm labor costs in Mexico and a growing awareness on the part of growers of the need for supply control to prevent market surpluses. Florida producers seem likely to retain or improve their share of the market because of improved cultural practices, substantial tariff protection, and closer proximity with eastern U.S. markets. Their Mexican competitors face the prospect of still higher farm wage costs.
The Sylvester equation and integrable equations: I. The Korteweg-de Vries system and sine-Gordon equation

description: The paper is to reveal the direct links between the well known Sylvester equation in matrix theory and some integrable systems. Using the Sylvester equation $\boldsymbol{K} \boldsymbol{M}+\boldsymbol{M} \boldsymbol{K}=\boldsymbol{r}\, \boldsymbol{s}^{T}$ we introduce a scalar function $S^{(i,j)}=\boldsymbol{s}^{T}\, \boldsymbol{K}^j(\boldsymbol{I}+\boldsymbol{M})^{-1}\boldsymbol{K}^i\boldsymbol{r}$ which is defined as same as in discrete case. $S^{(i,j)}$ satisfy some recurrence relations which can be viewed as discrete equations and play indispensable roles in deriving continuous integrable equations. By imposing dispersion relations on $\boldsymbol{r}$ and $\boldsymbol{s}$, we find the Korteweg-de Vries equation, modified Korteweg-de Vries equation, Schwarzian Korteweg-de Vries equation and sine-Gordon equation can be expressed by some discrete equations of $S^{(i,j)}$ defined on certain points. Some special matrices are used to solve the Sylvester equation and prove symmetry property $S^{(i,j)}=S^{(i,j)}$. The solution $\boldsymbol{M}$ provides $τ$ function by $τ=|\boldsymbol{I}+\boldsymbol{M}|$. We hope our results can not only unify the Cauchy matrix approach in both continuous and discrete cases, but also bring more links for integrable systems and variety of areas where the Sylvester equation appears frequently.

description: Semi-Lagrangian (SL) schemes are known as a major numerical tool for solving transport equations with many advantages and have been widely deployed in the fields of computational fluid dynamics, plasma physics modeling, numerical weather prediction, among others. In this work, we develop a novel machine learning-assisted approach to accelerate the conventional SL finite volume (FV) schemes. The proposed scheme avoids the expensive tracking of upstream cells but attempts to learn the SL discretization from the data by incorporating specific inductive biases in the neural network, significantly simplifying the algorithm implementation and leading to improved efficiency. In addition, the method delivers sharp shock transitions and a level of accuracy that would typically require a much finer grid with traditional transport solvers. Numerical tests demonstrate the effectiveness and efficiency of the proposed method.

description: Cosmological models in 1+1 dimensions are an ideal setting for investigating the quantum structure of inflationary dynamics -- gravity is renormalizable, while there is room for spatial structure not present in the minisuperspace approximation. We use this fortuitous convergence to investigate the mechanism of slow-roll eternal inflation. A variant of 1+1 Liouville gravity coupled to matter is shown to model precisely the scalar sector of cosmological perturbations in 3+1 dimensions. A particular example of quintessence in 1+1d is argued on the one hand to exhibit slow-roll eternal inflation according to standard criteria; on the other hand, a field redefinition relates the model to pure de Sitter gravity coupled to a free scalar matter field with no potential. This and other examples show that the standard logic leading to slow-roll eternal inflation is not invariant under field redefinitions, thus raising concerns regarding its validity. Aspects of the quantization of Liouville gravity as a model of quantum de Sitter space are also discussed.
