A two-stage approach to semilinear in-slide models
Creators: name: Zhou, Haibo

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2008

description: The semilinear in-slide models (SLIMs) have been shown to be effective method for normalizing microarray data (Fan, et al. 2004). Using a backfitting method, Fan, Peng and Huang (2005) proposed a profile least squares (PLS) estimation for the parametric and nonparametric components. The general asymptotic properties for their estimator is not developed. In this paper, we consider a new approach, two-stage estimation, which enables us to establish the asymptotic normalities for both of the parametric and nonparametric component estimators. We further propose a plug-in bandwidth selector using the asymptotic normality of the nonparametric component estimator. The proposed method allow for the modeling of the aggregated SLIMs case where we can explicitly show that taking the aggregated information into account can improve both of the parametric and nonparametric component estimator by the proposed two-stage approach. Some simulation studies are conducted to illustrate the finite sample performance of the proposed procedures.

description: In this paper, we carry out an in-depth theoretical investigation for inference with missing response and covariate data for general regression models. We assume that the missing data are Missing at Random (MAR) or Missing Completely at Random (MCAR) throughout. Previous theoretical investigations in the literature have focused only on missing covariates or missing responses, but not both. Here, we consider theoretical properties of the estimates under three different estimation settings: complete case analysis (CC), a complete response analysis (CR) that involves an analysis of those subjects with only completely observed responses, and the all case analysis (AC), which is an analysis based on all of the cases. Under each scenario, we derive general expressions for the likelihood and devise estimation schemes based on the EM algorithm. We carry out a theoretical investigation of the three estimation methods in the normal linear model and analytically characterize the loss of information for each method, as well as derive and compare the asymptotic variances for each method assuming the missing data are MAR or MCAR. In addition, a theoretical investigation of bias for the CC method is also carried out. A simulation study and real dataset are given to illustrate the methodology.

description: A novel thermodynamic integration (TI) scheme is presented to compute the crystal-liquid interfacial free energy ($γ_{\rm cl}$) from molecular dynamics simulation. The scheme is applied to a Lennard-Jones system. By using extremely short-ranged and impenetrable Gaussian flat walls to confine the liquid and crystal phases, we overcome hysteresis problems of previous TI schemes that stem from the translational movement of the crystal-liquid interface. Our technique is applied to compute $γ_{\rm cl}$ for the (100), (110) and (111) orientation of the crystalline phase at three temperatures under coexistence conditions. For one case, namely the (100) interface at the temperature $T=1.0$ (in reduced units), we demonstrate that finite-size scaling in the framework of capillary wave theory can be used to estimate $γ_{\rm cl}$ in the thermodynamic limit. Thereby, we show that our TI scheme is not associated with the suppression of capillary wave fluctuations.

Maximum likelihood inference for the Cox regression model with applications to missing covariates
Creators: name: Shao, Qi-Man
name: Ibrahim, Joseph G.
name: Chen, Ming-Hui
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: In this paper, we carry out an in-depth theoretical investigation for existence of maximum likelihood estimates for the Cox model (Cox, 1972, 1975) both in the full data setting as well as in the presence of missing covariate data. The main motivation for this work arises from missing data problems, where models can easily become difficult to estimate with certain missing data configurations or large missing data fractions. We establish necessary and sufficient conditions for existence of the maximum partial likelihood estimate (MPLE) for completely observed data (i.e., no missing data) settings as well as sufficient conditions for existence of the maximum likelihood estimate (MLE) for survival data with missing covariates via a profile likelihood method. Several theorems are given to establish these conditions. A real dataset from a cancer clinical trial is presented to further illustrate the proposed methodology.

description: Today, digital medical education requires building an individual trajectory and considering the students’ needs. Personalized learning is proved to be an effective model as it concerns self-organization learning and customized instruction. The findings show that the implementation of personalized learning model depends on the behavioral analytics and the students’ learning styles. The present research is aimed to assess the learning styles among medical students and to substantiate the choice of effective teaching methods. To achieve the research objectives, we applied the case study method among 167 students from three institutions of higher medical education in Ukraine. The findings showed that most students belong to the converger and accommodator learning style groups. Considering the Cohen’s approach, we found that implementation of personalized learning model in digital medical education based on behavioral analytics increased the efficiency of learning process in all three institutions. The average efficiency index amounts 3,9 %. This proves the idea of positive impact of personalized learning model based on behavioral analytics upon the enhancement of digital medical education. As a conclusion, we elaborated a set of teaching methods suitable for different groups to provide high-quality digital medical education. In addition, certain recommendations were developed for heterogeneous groups.

The penalized profile sampler
Creators: name: Kosorok, Michael R.
name: Cheng, Guang
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2009

description: The penalized profile sampler for semiparametric inference is an extension of the profile sampler method [9] obtained by profiling a penalized log-likelihood. The idea is to base inference on the posterior distribution obtained by multiplying a profiled penalized log-likelihood by a prior for the parametric component, where the profiling and penalization are applied to the nuisance parameter. Because the prior is not applied to the full likelihood, the method is not strictly Bayesian. A benefit of this approximately Bayesian method is that it circumvents the need to put a prior on the possibly infinite-dimensional nuisance components of the model. We investigate the first and second order frequentist performance of the penalized profile sampler, and demonstrate that the accuracy of the procedure can be adjusted by the size of the assigned smoothing parameter. The theoretical validity of the procedure is illustrated for two examples: a partly linear model with normal error for current status data and a semiparametric logistic regression model. Simulation studies are used to verify the theoretical results.

description: The Congruence Engine is a three-year research project that started in November 2021. It is using the latest digital techniques (including AI) to connect industrial history collections held in different museums and archives across the UK.  

It is one of five ‘Discovery Projects’ funded by the Arts and Humanities Research Council under the ‘Towards a National Collection’ funding stream. 

Until now, historians and curators have become used to a world where it has only been possible to work with a small selection of the sources – museum objects, archive documents, pictures, films, maps, or publications, for example – potentially relevant to the history they want to explore. We are working to overcome this major constraint on the histories that can be created by curators and historians, whether they do history for fun or as a job.

The project is uniting in collaboration a unique combination of skills and interests. We have established that, however sophisticated the digital techniques you use, the human factor is always essential to the creation of usable digital data and interpretations. We call this combination a ‘social machine’. In this, individuals and groups motivated by personal and professional interests can work to enable programs to work at scale on data relating to multiple collections. This will make it possible, for example, to link together similar objects between collections; to connect objects to pictures, films and archives, or to link items from any collection to the historical or contemporary literature that describe, and make sense of, them.

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: How to take advantage of the available auxiliary covariate information when the primary covariate of interest is not measured is a frequently encountered question in biomedical study. In this paper, we consider the multivariate failure times regression analysis in which the primary covariate is assessed only in a validation set but a continuous auxiliary covariate for it is available for all subjects in the study cohort. Under the frame of marginal hazard model, we propose to estimate the induced relative risk function in the nonvalidation set through kernel smoothing method and then obtain an estimated pseudo-partial likelihood function. The proposed estimated pseudo-partial likelihood estimator is shown to be consistent and asymptotically normal. We also give an estimator of the marginal cumulative baseline hazard function. Simulations are conducted to evaluate the finite sample performance of our proposed estimator. The proposed method is illustrated by analyzing a heart disease data from Studies of Left Ventricular Dysfunction (SOLVD).

Multi-terminal Anderson impurity model in nonequilibrium: Analytical perturbative treatment

Subjects: subject: Mesoscale and Nanoscale Physics (cond-mat.mes-hall)

description: We study the nonequilibrium spectral function of the single-impurity Anderson model connecting with multi-terminal leads. The full dependence on frequency and bias voltage of the nonequilibrium self-energy and spectral function is obtained analytically up to the second-order perturbation regarding the interaction strength $U$. High and low bias voltage properties are analyzed for a generic multi-terminal dot, showing a crossover from the Kondo resonance to the Coulomb peaks with increasing bias voltage. For a dot where the particle-hole symmetry is not present, we construct a current-preserving evaluation of the nonequilibrium spectral function for arbitrary bias voltage. It is shown that finite bias voltage does not split the Kondo resonance in this order, and no specific structure due to multiple leads emerges. Overall bias dependence is quite similar to finite temperature effect for a dot with or without the particle-hole symmetry.

Simultaneous multiple response regression and inverse covariance matrix estimation via penalized Gaussian maximum likelihood
Creators: name: Lee, Wonyul
name: Liu, Yufeng
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2012

description: Multivariate regression is a common statistical tool for practical problems. Many multivariate regression techniques are designed for univariate response cases. For problems with multiple response variables available, one common approach is to apply the univariate response regression technique separately on each response variable. Although it is simple and popular, the univariate response approach ignores the joint information among response variables. In this paper, we propose three new methods for utilizing joint information among response variables. All methods are in a penalized likelihood framework with weighted L1 regularization. The proposed methods provide sparse estimators of conditional inverse co-variance matrix of response vector given explanatory variables as well as sparse estimators of regression parameters. Our first approach is to estimate the regression coefficients with plug-in estimated inverse covariance matrices, and our second approach is to estimate the inverse covariance matrix with plug-in estimated regression parameters. Our third approach is to estimate both simultaneously. Asymptotic properties of these methods are explored. Our numerical examples demonstrate that the proposed methods perform competitively in terms of prediction, variable selection, as well as inverse covariance matrix estimation.

description: We report our measurement of the trigonometric distance and proper motion IRAS 20056+3350, obtained from the annual parallax of H2O masers. Our distance of D = 4.69 +0.65-0.51 kpc, which is more than two times larger than the near kinematic distance adopted in the literature, places IRAS 20056+3350 at the leading tip of the Local arm, and proximal to the Solar circle. Using our distance we re-evaluate past observations to reveal IRAS 20056+3350 as a site of massive star formation at a young stage of evolution. This result is consistent with the spectral energy distribution of the source evaluated with published photometric data from UKIDSS, WISE, AKARI, IRAS and sub-millimetre continuum. Both analytical approaches reveal the luminosity of the region to be 2.4 x 10^4 Lo, and suggest that IRAS 20056+3350 is forming an embedded star of 16 Mo. We estimated the proper motion of IRAS 20056+3350 to be ($μ_α\cosδ$, $μ_δ$) = ($-2.62\pm0.33$, $-5.65\pm0.52$) mas yr$^{-1}$ from the group motion of H$_{2}$O masers, and use our results to estimate the angular velocity of Galactic rotation at the Galactocentric distance of the Sun, $Ω_{0} = 28.71\pm0.63$ km s$^{-1}$ kpc$^{-1}$, which is consistent with the values obtained for other tangent point and Solar circle objects.

description: Thermal annealing of interstellar ices takes place in several stages of star formation. Knowledge of this process comes from a combination of astronomical observations and laboratory simulations under astrophysically relevant conditions. For the first time we present the results of temperature programmed desorption (TPD) experiments with pre-cometary ice analogs composed of up to five molecular components: H2 O, CO, CO2, CH3 OH, and NH3 . The experiments were performed with an ultra-high vacuum chamber. A gas line with a novel design allows the controlled preparation of mixtures with up to five molecular components. Volatiles desorbing to the gas phase were monitored using a quadrupole mass spectrometer, while changes in the ice structure and composition were studied by means of infrared spectroscopy. The TPD curves of water ice containing CO, CO2, CH3 OH, and NH3 present desorption peaks at temperatures near those observed in pure ice experiments, volcano desorption peaks after water ice crystallization, and co-desorption peaks with water. Desorption peaks of CH3 OH and NH3 at temperatures similar to the pure ices takes place when their abundance relative to water is above 3%, approx., in the ice matrix. We found that CO, CO2, and NH3 also present co-desorption peaks with CH3 OH, which cannot be reproduced in experiments with binary water-rich ice mixtures. These are extensively used in the study of thermal desorption of interstellar ices. These results reproduce the heating of circumstellar ices in hot cores and can be also applied to the late thermal evo- lution of comets. In particular, TPD curves represent a benchmark for the analysis of the measurements that mass spectrometers on board the ESA-Rosetta cometary mission will perform on the coma of comet 67P/Churyumov-Gerasimenko, which will be active before the arrival of Rosetta according to our predictions.

description: Pflanzenbauliche Produktionssysteme können durch unterschiedliche Parameter bewertet werden, z. B. durch Produktivität und Ressourcennutzungseffizienz. Durch den Flächenbezug der pflanzenbaulichen Produktivität stellt diese jedoch selbst eine Ressourcennutzungseffizienz dar, die Flächennutzungseffizienz. Nach dem Gesetz abnehmenden Grenznutzens stehen Flächennutzungseffizienz und andere Ressourcennutzungseffizienzen in einem scheinbar negativen Verhältnis zueinander. Positive Interaktionen zwischen einzelnen inputs (Düngung, Pflanzenschutz, Sortenleistung) und technischer Fortschritt können jedoch dazu führen, dass sich sowohl Produktivität als auch Ressourcennutzungseffizienz über die Zeit parallel positiv entwickeln. Nach einer Intensivierungsphase der pflanzenbaulichen Produktion in den 1980er bis Mitte der 1990er Jahre mit Ertragssteigerungen, aber generell abnehmenden Ressourcennutzungseffizienzen sind solche Entwicklungen in einigen Bereichen erkennbar, werden jedoch aktuell durch die erkennbaren Wirkungen des Klimawandels zunehmend in Frage gestellt. Vor dem Hintergrund global zunehmender Landknappheit und häufig nichtlinearer Beziehungen zwischen Produktionsintensität und Umweltwirkungen stellt daher die parallele Optimierung mehrerer Ressourcennutzungseffizienzen und damit explizit der Produktivität nach wie vor das Kernproblem pflanzenbaulicher Forschung dar.

description: We have considered the quantum dynamics of an array of nSQUIDs -- two-junction SQUIDs with negative mutual inductance between their two arms. Effective dual-rail structure of the array creates additional internal degree of freedom for the fluxons in the array, which can be used to encode and transport quantum information. Physically, this degree of freedom is represented by electromagnetic excitations localized on the fluxon. We have calculated the spatial profile and frequency spectrum of these excitations. Their dynamics can be reduced to two quantum states, so that each fluxons moving through the array carries with it a qubit of information. Coherence properties of such a propagating qubits in the nSQUID array are characterized by the dynamic suppression of the low-frequency decoherence due to the motion-induced spreading of the noise spectral density to a larger frequency interval.

Direct detection of cosmic rays: through a new era of precision measurements of particle fluxes
Creators: name: Mocchiutti, Emiliano
Publisher: name: arXiv
Year: 2014
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)
subject: FOS: Physical sciences

description: In the last years the direct measurement of cosmic rays received a push forward by the possibility of conducting experiments on board long duration balloon flights, satellites and on the International Space Station. The increase in the collected statistics and the technical improvements in the construction of the detectors permit the fluxes measurement to be performed at higher energies with a reduced discrepancy among different experiments respect to the past. However, high statistical precision is not always associated to the needed precision in the estimation of systematics; features in the particle spectra can be erroneously introduced or hidden. A review and a comparison of the latest experimental results on direct cosmic rays measurements will be presented with particular emphasis on their similarities and discrepancies.

description: Precision farming hat in den letzten drei Jahrzehnten in vielen Bereichen der landwirtschaftlichen Produktion grundlegend neue Verfahren bereitgestellt. Im Rahmen der Digitalisierung oder des digital farming werden diese Verfahren zukünftig weiter optimiert und erweitert. Dem Landwirt wird dadurch ermöglicht, nach wie vor produktiv, aber auch insbesondere nachhaltig und umweltschonend zu wirtschaften. Der Landwirt wird auch in Zukunft, trotz digitaler Automatisierung, wichtiger Teil des Betriebsmanagements bleiben, weil die dynamische Systemkomplexität groß ist und diese ihm in der Zukunft nach wie vor eine hohe Entscheidungskompetenz abverlangt. Digital automatisierte Maschinen mit sehr flexibel-vielfältiger Sensorik und Aktorik können eine neue Qualität der landwirtschaftlichen Produktion schaffen, indem sie die Intensität der Biologisierung der Prozesse fördern und dadurch Betriebsmittel minimieren und biologische Diversität steigern. Der Landwirt muss sich allerdings auf die Eigenheiten der digitalen Technologien einstellen und diese kritisch begleiten.

description: Diese Gleichung stimmt vordergründig, wird aber der Komplexität des Pflanzenbaus nicht gerecht. Erstens sind die Begriffe „intensiv“ und „extensiv“ auf das Verhältnis aller knappen inputs (nicht nur Fläche) und outputs (Landwirtschaft ist multifunktional) zu beziehen. Zweitens ist eine erhebliche Verbesserung der Umweltwirkungen der Landwirtschaft nicht unbedingt mit einer massiven Verringerung der Produktion verbunden. Drittens ist eine Erhöhung der Produktion im Rest der Welt nicht grundsätzlich mit negativen Nachhaltigkeitswirkungen verbunden (in vielen Ländern ist die Ertragslücke wesentlich höher als in Deutschland). Viertens würde ein nachhaltigerer Konsum, insbesondere eine Verringerung des Konsums tierischer Produkte, erheblichen Spielraum für einen nachhaltigeren Pflanzenbau eröffnen. Hieraus folgt für den Pflanzenbau in Deutschland: (1) Eine einseitige „intensiv/extensiv-Diskussion“ ist nicht hilfreich – die Produktion von Nahrungsmitteln ist ein wichtiges, aber nur ein Ziel der Landwirtschaft. (2) Zielkonflikte sollten so weit wie möglich produktionstechnisch aufgelöst werden. (3) Angesichts des Nicht-Erreichens zentraler Umweltziele scheint eine Verringerung zentraler inputs allerdings notwendig. (4) Wir sollten den Ressourcenanspruch unserer Ernährung deutlich reduzieren.

TANK ACTIVE-PRESSURIZATION
CRYOGENIC

TURBULENCE
THERMAL STRATIFICATION

description: In this paper, a numerical methodology to study the active-pressurization inside cryogenic tanks is proposed and validated with the results of an active-pressurization experiment in normal gravity, inside a liquid nitrogen (N2) tank. The tank is modeled as 20 axisymmetric, a fluid-wall conjugate heat transfer model is used, and the two-phase fluid interface is tracked with the Volume-of-Fluid (VOF) method. The results show that the experimental data are accurately reproduced with the SST k -w with low-Re corrections turbulence model, and that the modeling of the shutdown of pressurant gas injection requires some attention from a numerical standpoint.
