description: This dissertation proposes novel Bayesian semiparametric and nonparametric methods for complex, large and potentially high-dimensional longitudinal and survival data. The first part, comprising the bulk of this thesis, develops sophisticated dynamic partition models for longitudinal data that allow common features to be shared across some time segments while differing across others. These ideas are then specifically adapted to develop novel drift-diffusion models for the analysis of behavioral data on category learning in auditory neuroscience. The second part of this work proposes a bivariate survival regression method, borrowing information across two outcomes via common features in parts of the induced marginal partitions. In terms of flexibility and interpretability, the methods presented here provide significant improvements over many previously available tools and techniques, leading to interesting, novel and meaningful inference in many diverse application areas.
Survival of laboratory fabricated space maintainers

description: Objective: Few studies have examined the longevity of a large sample of space maintainers. The aim of this research was to determine if appliance, patient or provider factors played a role in the success and survival of laboratory-fabricated fixed space maintainers. Methods: A retrospective chart review was conducted of laboratory-fabricated fixed passive space maintainers inserted between January 1, 2000 and December 31, 2003 in a metro Vancouver pediatric dentistry/orthodontic practice. Appliances were followed until removal or, if still in use, to study’s end point; no observations were censored. Patients lost to follow-up were excluded. All appliances had been prepared and inserted using a consistent, meticulous technique. If an appliance failed prematurely, reasons for failure, e.g. cement loss, solder breakage, eruption interference, were recorded. Other data collected included child’s date of birth, gender, cement type, caries rate, oral hygiene score and patient cooperation at the time of appliance placement. Statistical analyses included descriptive statistics, Kaplan-Meier and the Mantel-Cox Log-rank survival analysis. Results: Of the original sample of 1218, 892 appliances were analyzed. The sample included band and loop (B&L), lingual holding arch (LHA) and Nance appliances from 692 subjects. Subjects were analyzed by specialty: pediatric (n=370), orthodontic (n=322). The mean age at insertion was 9(2) years. For sixty-five percent of subjects (n=452), appliances were deemed ‘successful’ i.e., “did what the clinician expected”. After controlling for the effect of other explanatory variables, type of space maintainer (p<0.03), patient gender (p=0.003) and age at insertion (p<0.0001) were all significantly related to success. Mandibular B&Ls had the longest median survival time (time for half of appliances to fail, MST) of 38 months; maxillary B&Ls, the lowest MST of 22 months. The MST of LHA and Nance were 25 months and 26 months, respectively. In the failure group, no statistical significant differences were found in the MST of space maintainers when appliance type was considered. Conclusion: The majority of the space maintainers lasted their anticipated lifetime. Appliance type, patient gender and age at insertion were significantly associated with outcomes.

description: In this paper we consider a one dimensional liner piecewise-smooth discontinuous map. It is well known that stable periodic orbits exist in this type of map for a specific parameter region. It is also known that the corresponding bifurcation phenomena termed as "period adding bifurcation" exhibits a special structure for such case. In last couple of years, various authors have analyzed this structure using border collision bifurcation (BCB) curves and given characterization for various parameter regions. In this paper we have analyzed a specific parameter space using a different method. We show that this method enables us to pose some interesting problems like: is there any relationship between the period of an orbit and the cardinality of orbits? We prove that such a relationship exists and exactly ϕ(n) orbits exist for a period n where ϕ is the Euler's number. We propose an algorithm which gives the location of fixed points of all such ϕ(n) distinct orbits and gives their range of existence with respect to parameters. Further, we show that using a novel algorithm the computations to find their range of existence can be reduced.

Life and Quantum Biology, an Interdisciplinary Approach

description: The rapidly increasing interest in the quantum properties of living matter stimulates a discussion of the fundamental properties of life as well as quantum mechanics. In this discussion often concepts are used that originate in philosophy and ask for a philosophical analysis. In the present work the classic philosophical tradition based on Aristotle and Aquinas is employed which surprisingly is able to shed light on important aspects. Especially one could mention the high degree of unity in living objects and the occurrence of thorough qualitative changes. The latter are outside the scope of classical physics where changes are restricted to geometrical rearrangement of microscopic particles. A challenging approach is used in the philosophical analysis as the empirical evidence is not taken from everyday life but from 20th century science (quantum mechanics) and recent results in the field of quantum biology. In the discussion it is argued that quantum entanglement is possibly related to the occurrence of life. Finally it is recommended that scientists and philosophers should be open for dialogue that could enrich both. Scientists could redirect their investigation, as paradigm shifts like the one originating from philosophical evaluation of quantum mechanics give new insight about the relation between the whole en the parts. Whereas philosophers could use scientific results as a consistency check for their philosophical framework for understanding reality.

Ten-month-olds' evaluations of accidental and intentional actions
Creators: name: Le, T. Doan
Publisher: name: University of British Columbia
Year: 2013

description: Mature moral judgments rely on the analysis of both the outcomes of others’ actions and the mental states that drive them. Past research has shown that when there is conflict between outcome and intention, young children rely on outcome information to evaluate others, while older children and adults privilege intention (Piaget, 1932/1965). This suggests that there is a shift from outcome-based to intention-based judgments occurring in development. However, the current study suggests that even 10-month-old infants evaluate moral agents on the basis of their underlying mental states. Infants were presented with puppet shows in which a protagonist was either intentionally or accidentally helped or hindered. Infants were then given a forced choice between the accidental and intentional puppets. Results indicate that infants’ preference for the accidental versus the intentional character differed by condition [χ²(1, N = 60)= 11.28, p < .001, ϕ = .43]; infants preferred intentional to accidental helpers (Binomial, p < .05), but preferred accidental to intentional hinderers (Binomial, p < .05). These results suggest that the capacity to evaluate others on the basis of intention arises much earlier on in development than previously suggested and contradicts earlier claims of a developmental shift from outcome- to intention-based judgments.

description: The spin dynamics and magnetic excitations of the slightly distorted triangular s = 3/2 system alpha-CaCr2O4 are investigated by means of Raman spectroscopy and electron spin resonance (ESR) to elucidate its peculiar magnetic properties. Two-magnon excitations in circular RL symmetry show a multi-maximum structure with a dominant spectral weight at low energies. The temperature dependence of the ESR linewidth is described by a critical broadening DeltaHpp(T) ~ (T - T_N)^{-p} with the exponent p = 0.30(3) - 0.38(5) for temperatures above T_N = 42.6 K. The exponent is much smaller than that of other s = 3/2 triangular lattices. This is ascribed to soft roton-like modes, indicative of the instability of a helical 120° phase. As an origin we discuss a complex spin topology formed by four inequivalent nearest neighbor and sizable next-nearest neighbor interactions.

description: We report a comprehensive angle-resolved photoemission spectroscopy study of the tridimensional electronic bands in the recently discovered Fe selenide superconductor (Tl,Rb)$_y$Fe$_{2-x}$Se$_2$ ($T_c=32$ K). We determined the orbital characters and the $k_z$ dependence of the low energy electronic structure by tuning the polarization and the energy of the incident photons. We observed a small 3D electron Fermi surface pocket near the Brillouin zone center and a 2D like electron Fermi surface pocket near the zone boundary. The photon energy dependence, the polarization analysis and the local-density approximation calculations suggest a significant contribution from the Se 4$p_z$ and Fe 3$d_{xy}$ orbitals to the small electron pocket. We argue that the emergence of Se 4$p_z$ states might be the cause of the different magnetic properties between Fe chalcogenides and Fe pnictides.

Mechanical Responses and Stress Fluctuations of a Supercooled Liquid in a Sheared Non-Equilibrium State

description: A steady shear flow can drive supercooled liquids into a non-equilibrium state. Using molecular dynamics simulations under steady shear flow superimposed with oscillatory shear strain for a probe, non-equilibrium mechanical responses are studied for a model supercooled liquid composed of binary soft spheres. We found that even in the strongly sheared situation, the supercooled liquid exhibits surprisingly isotropic responses to oscillating shear strains applied in three different components of the strain tensor. Based on this isotropic feature, we successfully constructed a simple two-mode Maxwell model that can capture the key features of the storage and loss moduli, even for highly non-equilibrium state. Furthermore, we examined the correlation functions of the shear stress fluctuations, which also exhibit isotropic relaxation behaviors in the sheared non-equilibrium situation. In contrast to the isotropic features, the supercooled liquid additionally demonstrates anisotropies in both its responses and its correlations to the shear stress fluctuations. Using the constitutive equation (a two-mode Maxwell model), we demonstrated that the anisotropic responses are caused by the coupling between the oscillating strain and the driving shear flow. We measured the magnitude of this violation in terms of the effective temperature. It was demonstrated that the effective temperature is notably different between different components, which indicates that a simple scalar mapping, such as the concept of an effective temperature, oversimplifies the true nature of supercooled liquids under shear flow. An understanding of the mechanism of isotropies and anisotropies in the responses and fluctuations will lead to a better appreciation of these violations of the FDT, as well as certain consequent modifications to the concept of an effective temperature.

description: We study solvable spin chains, one-dimensional massless Dirac fermions, and conformal field theories (CFTs) with sine-square deformation (SSD), in which the Hamiltonian density is modulated by the function $f(x)=\sin^2 (πx/\ell)$, where $x$ is the position and $\ell$ is the length of the system. For the XY chain and the transverse field Ising chain at criticality, it is shown that the ground state of an open system with SSD is identical to that of a uniform chain with periodic boundary conditions. The same holds for the massless Dirac fermions with SSD, corresponding to the continuum limit of the gapless XY chain. For general CFTs, we find that the Hamiltonian of a system with SSD has an expression in terms of the generators of the Virasoro algebra. This allows us to show that the vacuum state is an exact eigenstate of the sine-square deformed Hamiltonian. Furthermore, for a restricted class of CFTs associated with affine Lie (Kac-Moody) algebras, including $c=1$ Gaussian CFT, we prove that the vacuum is an exact ground state of the deformed Hamiltonian. This explains why the SSD has succeeded in suppressing boundary effects in one-dimensional critical systems, as observed in previous numerical studies.

description: Neutron and x-ray scattering experiments have provided mounting evidence for spin and charge ordering phenomena in underdoped cuprates. These range from early work on stripe correlations in Nd-LSCO to the latest discovery of charge-density-waves in YBCO. Both phenomena are characterized by a pronounced dependence on doping, temperature, and an externally applied magnetic field. Here we show that these electron-lattice instabilities exhibit also a previously unrecognized bulk-surface dichotomy. Surface-sensitive electronic and structural probes uncover a temperature-dependent evolution of the CuO2 plane band dispersion and apparent Fermi pockets in underdoped Bi2201, which is directly associated with an hitherto-undetected strong temperature dependence of the incommensurate superstructure periodicity below 130K. In stark contrast, the structural modulation revealed by bulk-sensitive probes is temperature independent. These findings point to a surface-enhanced incipient charge-density-wave instability, driven by Fermi surface nesting. This discovery is of critical importance in the interpretation of single-particle spectroscopy data and establishes the surface of cuprates and other complex oxides as a rich playground for the study of electronically soft phases.

description: The common chinch bug (Blissus leucopterus) is a serious pest of sorghum, especially in warm and dry conditions. Both nymphs and adults suck sap from the base of sorghum plants, leading to yellowing, wilting, and even plant death in severe cases. Damage is more noticeable during drought stress. Chinch bugs usually congregate at the base of plants and move upward as the plant grows. Management includes early planting, crop rotation, destruction of crop residues, and the use of resistant varieties. Insecticides may be applied if infestations are heavy and economic thresholds are crossed.

Schloß Babelsberg diente von 1835 bis 1888 als Sommersitz des Prinzen und späteren Kaisers Wilhelm I. und seiner Gemahlin Kaiserin Augusta. Als mittelalterliche Burg erbaut, spiegelt es wie kein anderes unter den Potsdamer Schlössern der Hohenzollern die Anschauungen und Lebensweise der damaligen Epoche wieder. Das Schloß wurde nach einem Entwurf Karl Friedrich Schinkels in zwei Bauphasen erbaut. Der erste Bauabschnitt erfolgte zwischen 1834 und 1835. 1844 bis 1849 kam es zu Um- und Erweiterungsbauten unter Ludwig Persius, Johann Heinrich Strack und Martin Gottgetreu. Die Bibliothek wurde im Zuge der Schloßerweiterung 1844-49 an Stelle zweier Hofdamenzimmer eingerichtet. Die Entwürfe zur Raumgestaltung lieferte J. H. Strack. Im Hinblick auf die Wiederherstellung der ursprünglichen Raumfassung von 1849 erfolgte eine restauratorische Befundsicherung des Raumes. Dabei wurden die Fassungen auf sämtlichen Oberflächen untersucht und dokumentiert. Weiterhin werden die Schäden und ihre Ursachen dargestellt. Die Untersuchung schließt auch die Recherche nach dem ursprünglichen Inventar ein. Anhand der Ergebnisse zum Umfang und Erhaltungszustand des originalen Bestandes werden Vorschläge zur Konservierung und Restaurierung des Raumes erstellt.

description: In this note we construct rigidly supersymmetric gauged sigma models and gauge theories on certain Einstein four-manifolds, and discuss constraints on these theories. In work elsewhere, it was recently shown that on some nontrivial Einstein four-manifolds such as AdS$_4$, N=1 rigidly supersymmetric sigma models are constrained to have target spaces with exact Kähler forms. Similarly, in gauged sigma models and gauge theories, we find that supersymmetry imposes constraints on Fayet-Iliopoulos parameters, which have the effect of enforcing that Kähler forms on quotient spaces be exact. We also discuss general aspects of universality classes of gauged sigma models, as encoded by stacks, and also discuss affine bundle structures implicit in these constructions.

description: Additive manufacturing (AM) of highly complex three-dimensional metal structures using selective laser melting (SLM) is increasingly gaining interest in numerous fields of application. The new design freedom combined with enhanced lightweight design methods shows an enormous potential, especially in the aerospace industry. Thereby, metal alloys with a high strength to weight ratio play an important role. Although several titanium and aluminium alloys have been SLM-processed successfully, the high strength-aluminium alloy EN AW 7075 remains a challenge.

The major challenge in SLM processing of EN AW 7075 is the high sensitivity to hot cracks due to process related temperature gradients and rapid solidification. Preheating represents a promising approach to reduce temperature gradients and minimize shrinking between the layers. This investigation focuses on optimum SLM process parameters and reduction of hot cracking of EN AW 7075. In the first step, hot crack formation was evaluated from single track experiments to identify the most promising range of laser parameters. Subsequently, multi-layer parameter studies were carried using EN AW 7075 powder and preheating of up to 350 °C.

description: We analyze the valley composition of one electron bound to a shallow donor close to a Si/barrier interface as a function of an applied electric field. A full six-valley effective mass model Hamiltonian is adopted. For low fields, the electron ground state is essentially confined at the donor. At high fields the ground state is such that the electron is drawn to the interface, leaving the donor practically ionized. Valley splitting at the interface occurs due to the valley-orbit coupling, V_vo^I = |V_vo^I| e^{i theta}. At intermediate electric fields, close to a characteristic shuttling field, the electron states may constitute hybridized states with valley compositions different from the donor and the interface ground states. The full spectrum of energy levels shows crossings and anti-crossings as the field varies. The degree of level repulsion, thus the width of the anti-crossing gap, depends on the relative valley compositions, which vary with |V_vo^I|, theta and the interface-donor distance. We focus on the valley configurations of the states involved in the donor-interface tunneling process, given by the anti-crossing of the three lowest eigenstates. A sequence of two anti-crossings takes place and the complex phase theta affects the symmetries of the eigenstates and level anti-crossing gaps. We discuss the implications of our results on the practical manipulation of donor electrons in Si nanostructures.

description: We propose a novel distributed random access scheme for wireless networks based on slotted ALOHA, motivated by the analogies between successive interference cancellation and iterative belief-propagation decoding on erasure channels. The proposed scheme assumes that each user independently accesses the wireless link in each slot with a predefined probability, resulting in a distribution of user transmissions over slots. The operation bears analogy with rateless codes, both in terms of probability distributions as well as to the fact that the ALOHA frame becomes fluid and adapted to the current contention process. Our aim is to optimize the slot access probability in order to achieve rateless-like distributions, focusing both on the maximization of the resolution probability of user transmissions and the throughput of the scheme.

description: Skin models or phantoms are valuable tools used in biomaterial research to mimic the structure and function of human skin. Optical skin phantoms, in particular, have emerged as promising solutions for studying light interaction with human skin in various biomedical applications, including imaging and laser treatments. How-ever, current optical skin models have limitations in achieving accurate representations of the real skin. These models often fail to consider important factors such as skin color, skin thickness, integration of ap-pendages (e.g., hair follicles, sweat glands, sebaceous glands), and biological response. In this study, we present a novel approach to overcome the limitations of existing artificial skin phantoms by developing a 3D-printed bio-hybrid skin phantom. Our proposed model aims to replicate the optical and thermal proper-ties of human skin and the complex geometry of hair follicles. To achieve this, we combine a skin model mimicking the optical and thermal properties of human skin with the embedding of biological skin cells. The basis of our bio-hybrid skin model is a 3D-printed tissue phantom material that allows for the fabrication of hair follicle like structures. Subsequently, we incorporate biological cells, such as hair follicle cells, into the skin model and engineer induced hair follicle cells to simulate the effects of photothermal therapy on specif-ic cell populations. This enables a comprehensive study of the optical and thermal mechanisms involved in the complex interaction between skin tissue, hair, and the light source. Additionally, we investigate the influ-ence of skin structures, including skin thickness and color, on the outcomes of photothermal therapy. The knowledge gained from our bio-hybrid skin model extends beyond photothermal therapy applications. It can also contribute to the development and testing of other optical treatments, such photodynamic therapy or photobiomodulation. The novel approach provides a platform to study the optical and thermal interactions in biomedical applications. The insights gained from our bio-hybrid skin model have the potential to en-hance future advancements in the field of biomaterials.

This problem is equivalent to understanding quantum corrections to the metric on the hypermultiplet moduli space. We show how all these corrections, which include D-brane and NS5-brane instantons, are incorporated in the framework of the twistor approach, which provides a powerful mathematical description of hyperkahler and quaternion-Kahler manifolds. We also present new insights on S-duality, quantum mirror symmetry, connections to integrable models and topological strings.

Understanding of no-load power in low consistency refining
Creators: name: Rajabi Nasab, Nina
Publisher: name: University of British Columbia
Year: 2013

description: Low Consistency (LC) refining is the primary means of improving the strength and smoothness of paper by imparting energy to fibres through repeated fibre-bar interactions. The useful part of the energy modifies the morphology of the fibres and the remaining, no-load power, mainly overcomes the hydraulic, pumping and mechanical losses in the refiner. This thesis is aimed to explore the no-load power in LC refining both experimentally and computationally. The contribution of this thesis comes in three parts. Firstly, the effect of consistency, operational and plate design parameters on noload power was experimentally determined on two pilot scale LC refiners with different plate diameters. The obtained data were used to provide a statistical model for prediction of no-load power. To study the effect of diameter and groove depth, the no-load power consumption of some mills corresponding to their operating conditions, and the specifications of the relevant refiner discs were collected. Based on this model, no-load power is described in terms of two main components, hydraulic and pumping powers, and an empirical equation is proposed. Secondly, we numerically examined the two-dimensional flow of a Newtonian fluid in the gap formed between two opposing cavities which represent the cross-sectional flow in LC refiner. A large number of unsteady simulations were conducted to characterize the effect of gap size on the flow field over the range of velocities. Then, we examined material transport between the cavities by introducing a passive scalar to represent the motion of tracer particles. Over the range of parameters studied, we identify two characteristic flow fields, defined as either steady or unsteady. We also find that particles are transported to the region near the leading edges of the bars only under the conditions of unsteady flow. Thirdly, we extended the numerical study by characterizing the effect of cavity depth on the flow field over the range of velocities. We find that the aspect ratio of the cavity dictates three characteristic flow fields based on the number of vortices formed within cavity and we propose criteria for cavity aspect ratio in terms of the refiner application.

description: This paper presents a setup capable of producing a high-flux continuous beam of cold rubidium atoms for cavity QED experiments in the regime of strong coupling. A 2 $D^+$ MOT, loaded by rubidium getters in a dry film coated vapor cell, fed a secondary moving-molasses MOT (MM-MOT) at a rate of 1.5 x $10^{10}$ atoms/sec. The MM-MOT provided a continuous beam with tunable velocity. This beam was then directed through the waist of a 280 $μ$m cavity resulting in a Rabi splitting of more than +/- 10 MHz. The presence of sufficient number of atoms in the cavity mode also enabled splitting in the polarization perpendicular to the input. The cavity was in the strong coupling regime, with parameters (g, $κ$, $γ$)/2$π$ equal to (7, 3, 6)/ 2$π$ MHz.

description: The top eigenvalues of rank $r$ spiked real Wishart matrices and additively perturbed Gaussian orthogonal ensembles are known to exhibit a phase transition in the large size limit. We show that they have limiting distributions for near-critical perturbations, fully resolving the conjecture of Baik, Ben Arous and Péché [Duke Math. J. (2006) 133 205-235]. The starting point is a new $(2r+1)$-diagonal form that is algebraically natural to the problem; for both models it converges to a certain random Schrödinger operator on the half-line with $r\times r$ matrix-valued potential. The perturbation determines the boundary condition and the low-lying eigenvalues describe the limit, jointly as the perturbation varies in a fixed subspace. We treat the real, complex and quaternion ($β=1,2,4$) cases simultaneously. We further characterize the limit laws in terms of a diffusion related to Dyson's Brownian motion, or alternatively a linear parabolic PDE; here $β$ appears simply as a parameter. At $β=2$, the PDE appears to reconcile with known Painlevé formulas for these $r$-parameter deformations of the GUE Tracy-Widom law.

description: We report on the observation of quantum interference of the emission from two separate nitrogen vacancy (NV) centers in diamond. Taking advantage of optically induced spin polarization in combination with polarization filtering, we isolate a single transition within the zero-phonon line of the non-resonantly excited NV centers. The time-resolved two-photon interference contrast of this filtered emission reaches 66%. Furthermore, we observe quantum interference from dissimilar NV centers tuned into resonance through the dc Stark effect. These results pave the way towards measurement-based entanglement between remote NV centers and the realization of quantum networks with solid-state spins.

In-plane dissipation as a possible synchronization mechanism for terahertz radiation from intrinsic Josephson junctions of layered superconductors

description: Strong terahertz radiation from mesa structure of $\rm{Bi_2Sr_2CaCu_2O_{8+δ}}$ single crystal has been observed recently, where the mesa intrinsically forms a cavity. For a thick mesa of large number of junctions, there are many cavity modes with different wave vectors along the c-axis corresponding to almost degenerate bias voltages. The mechanism responsible for exciting the uniform mode which radiates coherent terahertz waves in experiments is unknown. In this work, we show that the in-plane dissipation selects the uniform mode. For perturbations with non-zero wave numbers along the c-axis, the in-plane dissipations are significantly enhanced, which prevent the excitation of corresponding cavity modes. Our analytical results are confirmed by numerical simulations.

subject: Horticultural crop protection (incl. pests, diseases and weeds)

description: The corn leaf aphid (Rhopalosiphum maidis) is a common pest of corn, especially during the early whorl and tasseling stages. Both nymphs and adults suck sap from leaves, whorls, and tassels, leading to stunted growth, poor pollination, and reduced grain set. Heavy infestations may result in sticky honeydew deposits, promoting sooty mold development. The pest is often favored by warm and dry weather. Management includes promoting natural enemies like lady beetles and lacewings, maintaining good crop vigor, and applying insecticides only when aphid populations exceed economic thresholds.
Valuation theory of exponential Hardy fields II: Principal parts of germs in the Hardy field of o-minimal exponential expansions of the reals
Creators: name: Kuhlmann, Franz-Viktor

Publisher: name: arXiv
Year: 2012
Subjects: subject: Logic (math.LO)
subject: FOS: Mathematics

description: We present a general structure theorem for the Hardy field of an o-minimal expansion of the reals by restricted analytic functions and an unrestricted exponential. We proceed to analyze its residue fields with respect to arbitrary convex valuations, and deduce a power series expansion of exponential germs. We apply these results to cast "Hardy's conjecture" (see \cite[p.111]{[KS]}) in a more general framework. This paper is a follow up to \cite{[K-K2]} and is partially based on unpublished results of \cite{[K-K]}. A previous version \cite{[K-K1]} (which was dedicated to Murray A. Marshall on his 60th birthday) remained unpublished. In \cite{[W]} our structure theorem for the residue fields was rediscovered and applied to the diophantine context. Due to this revived interest, we decided to rework the preprint \cite{[K-K1]} and submit it to the Proceedings Volume.

Light Deflection for relativistic space astrometry in closed form

description: Given the extreme accuracy reached by future global space astrometry, one needs a global relativistic modeling of observations. A relativistic definition of astrometric observables is then essential to find uniquely coordinates, parallax and proper motion of a stellar object. The standard procedure is to explicitly solve the null geodesic equations to describe the trajectory of a photon emitted by a celestial object and received by a moving observing satellite. However, this task can be avoided if one builds an astrometric set up using the recent formalism of time transfer functions.

Replication and Reproducibility in Social Sciences and Statistics: Context, Concerns, and Concrete Measures
Creators: name: Vilhuber, Lars
Publisher: name: Zenodo
Year: 2019

description: Abstract

Replicability is at the core of the scientific enterprise. In the past 30 years, recurring concerns about the extent of replicability (or lack thereof) of the research in various disciplines have surfaced, including in economics.

In this talk, I describe the context in which the current discussion in the social science is occurring: what are the definitions of replicability and reproducibility, what is failing, and to what extent. In particular, I discuss the concerns in economics: to what extent is this a problem in economics, what are the approaches that are being considered, and what are the possible broader implications of those approaches. Finally, I discuss the concrete measures that are being implemented under my guidance at the American Economic Association, and that are being discussed in the broader economics community.

The solutions to these problems will change the way research will be taught and conducted, in economics in particular, and in the social sciences more broadly. The implications affect undergraduate and graduate teaching, research infrastructure, and habits.
