description: Gradient descent method, as one of the major methods in numerical optimization, is the key ingredient in many machine learning algorithms. As one of the most fundamental way to solve the optimization problems, it promises the function value to move along the direction of steepest descent. For the vast resource consumption when dealing with high-dimensional problems, a quantum version of this iterative optimization algorithm has been proposed recently[arXiv:1612.01789]. Here, we develop this protocol and implement it on a quantum simulator with limited resource. Moreover, a prototypical experiment was shown with a 4-qubit Nuclear Magnetic Resonance quantum processor, demonstrating a optimization process of polynomial function iteratively. In each iteration, we achieved an average fidelity of 94\% compared with theoretical calculation via full-state tomography. In particular, the iterative point gradually converged to the local minimum. We apply our method to multidimensional scaling problem, further showing the potentially capability to yields an exponentially improvement compared with classical counterparts. With the onrushing tendency of quantum information, our work could provide a subroutine for the application of future practical quantum computers.

description: The young sigma Orionis cluster is an indispensable basis for understanding the formation and evolution of stars, brown dwarfs and planetary-mass objects. Our knowledge of its stellar population is, however, incomplete. I present the Mayrit catalogue, that comprises most of the stars and high-mass brown dwarfs of the cluster. The basis of this work is an optical-near infrared correlation between the 2MASS and DENIS catalogues in a circular area of radius 30 arcmin centred on the OB-type binary sigma Ori AB. The analysis is supported on a bibliographic search of confirmed cluster members with features of youth and on additional X-ray, mid-infrared and astrometric data. I list 241 sigma Orionis stars and brown dwarfs with known features of youth, 97 candidate cluster members (40 are new) and 115 back- and foreground sources in the survey area. The 338 cluster members and member candidates constitute the Mayrit catalogue. This catalogue is a suitable input for studying the spatial ditribution, multiplicity, properties and frequency of discs and the complete mass function of sigma Orionis.

description: We investigate the phase behavior of athermal polymer/nanoparticle blends near a hard substrate. We apply the density functional theory of Tripathi and Chapman to these blends. We find a first order phase transition where the nanoparticles expel the polymer from the surface to form a monolayer. The transition density depends on the polymer length and the system bulk density. The effect is due to the packing entropy of the species and configurational entropy of the polymer. The simplicity of the system allows us to understand the so-called ``entropic-push'' observed in experiments.

description: We analyze the properties of a pulsed Coherent Population Trapping protocol that uses a controlled decay from the excited state in a $Λ$-level scheme. We study this problem analytically and numerically and find regimes where narrow transmission, absorption, or fluorescence spectral lines occur. We then look for optimal frequency measurements using these spectral features by computing the Allan deviation in the presence of ground state decoherence and show that the protocol is on a par with Ramsey-CPT. We discuss possible implementations with ensembles of alkali atoms and single ions and demonstrate that typical pulsed-CPT experiments that are realized on femto-second time-scales can be implemented on micro-seconds time-scales using this scheme.

description: The Quasi-Elastic (QE) contribution of the nuclear inclusive electron model developed in Nucl. Phys. A627 543 (1997) is extended to the study of neutrino/antineutrino Charged Current (CC) and Neutral Current (NC) induced nuclear reactions at intermediate energies. Long range nuclear (RPA) correlations, Final State Interaction (FSI) and Coulomb corrections are included within the model. RPA correlations are shown to play a crucial role in the whole range (100--500 MeV) of studied neutrino energies. Results for inclusive muon capture for different nuclei through the Periodic Table are also discussed. In addition, and by means of a Monte Carlo cascade method to account for the rescattering of the outgoing nucleon, we also study the CC and NC inclusive one nucleon knockout reactions off nuclei.

To this end we present a systematic methodology to determine and locate analytically isolated periodic points of algebraic maps. This approach can be useful to study other discrete dynamical systems with algebraic nature. Complementary results on the dynamics of the map associated with the Landen transformation are also presented.

description: This study investigates narrative comprehension and production in children with specific language impairment (SLI). Twelve children with SLI (mean age 5;8 years) and 12 typically developing children (mean age 5;6 years) participated in an eye-tracking experiment designed to investigate online narrative comprehension and production in Catalan- and Spanish-speaking children with SLI. The comprehension task involved the recording of eye movements during the visual exploration of successive scenes in a story, while listening to the associated narrative. With regard to production, the children were asked to retell the story, while once again looking at the scenes, as their eye movements were monitored. During narrative production, children with SLI look at the most semantically relevant areas of the scenes fewer times than their age-matched controls, but no differences were found in narrative comprehension. Moreover, the analyses of speech productions revealed that children with SLI retained less information and made more semantic and syntactic errors during retelling. Implications for theories that characterize SLI are discussed.

description: The magnetotransport properties of high mobility two dimensional electron gas have recently attracted a significant interest due to the discovery of microwave induced zero resistance states. Here we show experimentally that microwave irradiation with a photon energy much smaller than the spacing between Landau levels can induce a strong decrease in the four terminal resistance. This effect is not predicted by the bulk transport models introduced to explain zero resistance states, but can be naturally explained by an edge transport model. This highlights the importance of edge channels for zero resistance state physics that was proposed recently.

We prove in this article a positivity result on their coefficients, which extends a conjecture of S. Kerov. Our method, through decomposition of maps, gives a description of the coefficients of the k-th Kerov's polynomials using permutations in S(k). We also obtain explicit formulas or combinatorial interpretations for some coefficients. In particular, we are able to compute the subdominant term for character values on any fixed permutation (it was known for cycles).

Kinetics of Liquid Phase Oxidation of Cyclohexane

description: As a class of reactions, the liquid phase oxidation of hydrocarbons is a major source of many organic chemicals and plays a significant role in the modern petrochemical industry. The liquid phase oxidation of cyclohexane is a typical member of this class of reactions. As the products of this reaction, cyclohexanol and cyclohexanone which are in turn processed into caprolactam and adipic acid supply the main raw materials for the manufacture of Nylon-6 and Nylon-66. The primary intermediate of cyclohexane oxidation, cyclohexyl hydroperoxide, also has special industrial importance since it can produce other products with good selectivity under mild conditions. However, the oxidation of cyclohexane is relatively a difficult process and is plagued by the problem of selectivity since the desired products, i.e. cyclohexyl hydroperoxide, cyclohexanol and cyclohexanone, are intermediates in a sequence of reactions and overoxidation results easily in a number of useless by-products. A study of the kinetic mechanism of cyclohexane oxidation is therefore significant for the development of new technologies and the improvement of existing processes.

description: This investigation examined the importance of underlying motivations in predicting secure base support behavior, as well as the extent to which support motivations are predicted by individual differences in attachment orientation. Participants were 189 married couples who participated in two laboratory sessions. During a questionnaire session, couples completed assessments of their underlying motivations for providing, and for not providing, support for their partner's exploration (i.e., goal-strivings), as well as assessments of their typical secure base support behavior. In an observational session, couples engaged in a discussion of one member's personal goals, during which the partner's secure base support was assessed. Results revealed a variety of distinct motivations for providing, and for not providing, secure base support to one's partner, as well as theoretically expected links between these motivations and both secure base behavior and attachment orientation. This work establishes motivations as important mechanisms that underlie the effective or ineffective provision of relational support.

description: We have grown single crystals of the iron-based ladder material BaFe_2S_3, which is superconductive under high pressure, adopting different conditions. By comparing the behaviors of these samples, it is found that the in situ annealing process can affect the crystal structure and the electrical transport, enhance the antiferromagnetic transition temperature, and reduce the extrinsic ferromagnetic component of the system. An in-depth analysis indicates that the crystal quality is improved by the in situ annealing in terms of reducing both the Fe deficiency and the Fe impurity in the samples. The improvement of the sample quality will facilitate the investigations on the intrinsic properties of this material.

Neurovascular Coupling and Cerebral Perfusion Pressure- Biomarkers of Cerebral Health
Creators: name: Acharya, Deepshikha
Publisher: name: Carnegie Mellon University
Year: 2024
Subjects: Biomedical Engineering not elsewhere classified

description:  Under pressure, cerebral vessels in a healthy brain can alter their diameter to  maintain an adequate amount of blood flow and thereby a steady supply of oxygen  to the brain. This ability of the brain to compensate for perfusion pressure changes  is known as cerebral autoregulation. In several neuro-pathologies such as traumatic  brain injury, hydrocephalus, stroke, etc., this autoregulatory ability of the brain is  compromised. In such cases, a small change in pressure can cause drastic changes  in cerebral blood flow, leading to fatal secondary brain damages occurring from  ischemia (too little blood flow) or hyperemia (too much blood flow). Continuous  monitoring of cerebral health for timely diagnosis of such instances is essential to  improve patient outcome.  
This thesis proposes the use of neurovascular coupling as a non-invasive, bedside compatible biomarker for assessing cerebral perfusion pressures in relation to  autoregulatory health. Local neural activity and vascular tone are tightly coupled  in a healthy brain. This neuro-vascular coupling is essential to satiate oxidative metabolic needs from neuronal activity, regulate local tissue temperature, carry neuromodulators and post-synaptic wastes, etc. This coupling can be observed when  neural activity is evoked in a part of the brain using external stimuli causing in creases in local cerebral blood flow and volume in that region. It can also be studied  in a resting brain by mapping the coupling between local oxygen supply (cerebral  blood flow) and demand (cerebral metabolic rate of oxygen consumption), as well as  changes in resting neural signal power. However, in both instances, neurovascular coupling relies on adequate cerebral blood flow, which is impaired when autoregu lation breaks down.
 Here, through controlled pre-clinical experiments, I show that neurovascular  coupling– both stimulus- evoked, and at rest– can be used to assess cerebral health  at extreme cerebral perfusion pressures, linked to impaired autoregulation. Using  bedside compatible non-invasive measuring techniques such as diffuse optical spectroscopy and electroencephalography to assess neurovascular coupling I link changes  in neurovascular coupling to invasive measures of cerebral perfusion pressure. Finally, these techniques are used in a pediatric clinical setting to validate the clinical utility and translatability of neurovascular coupling as a biomarker for assessing  cerebral perfusion pressure and cerebral autoregulatory health.

description: We study bandstructure properties of periodic optical systems composed of lossy and intrinsically dispersive materials. To this end, we develop an analytical framework based on adjoint modes of a lossy periodic electromagnetic system and show how the problem of linearly dependent eigenmodes in the presence of material dispersion can be overcome. We then formulate expressions for the bandstructure derivative $(\partial ω) / (\partial \mathbf{k})$ (complex group velocity) and the local and total density of transverse optical states. Our exact expressions hold for 3D periodic arrays of materials with arbitrary dispersion properties and in general need to be evaluated numerically. They can be generalized to systems with two, one or no directions of periodicity provided the fields are localized along non-periodic directions. Possible applications are photonic crystals, metamaterials, metasurfaces composed of highly dispersive materials such as metals or lossless photonic crystals, metamaterials or metasurfaces strongly coupled to resonant perturbations such as quantum dots or excitons in 2D materials. For illustration purposes, we analytically evaluate our expressions for some simple systems consisting of lossless dielectrics with one sharp Lorentzian material resonance. Finally, we show how the perturbation of a periodic system with a sharp resonance modifies the bandstructure. By combining several Lorentz poles, this provides an avenue to perturbatively treat quite general material loss bands in photonic crystals.

description: This paper analyzes the optimal control problem of cubic polynomials on compact Lie groups from a Hamiltonian point of view and its symmetries. The dynamics of the problem is described by a presymplectic formalism associated with the canonical symplectic form on the cotangent bundle of the semidirect product of the Lie group and its Lie algebra. Using these control geometric tools, the relation between the Hamiltonian approach developed here and the known variational one is analyzed. After making explicit the left trivialized system, we use the technique of Marsden-Weinstein reduction to remove the symmetries of the Hamiltonian system. In view of the reduced dynamics, we are able to guarantee, by means of the Lie-Cartan theorem, the existence of a considerable number of independent integrals of motion in involution.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: ZigBee mesh network is very important research field in computer networks. However, the location of ZigBee coordinator plays a significant role in design and routing performance. In this paper, an extensive study on the factors that influence the performance of AODV routing protocol had been performed through the study of battery voltage decaying of nodes, neighboring tables, time delay and network topology structure. Simulation results reveal that the location of the coordinator within approximate equal distances to all nodes is more appropriate for lifelong batteries and AODV routing performance.

description: Galaxy-galaxy lensing uses the weak distortion of background sources to measure the mean excess surface density profile, ΔΣ(r), around a sample of foreground lensing galaxies. We develop a method for combining ΔΣ(r) with the galaxy-galaxy correlation function ξgg(r) to constrain the matter density parameter Ωm and the matter fluctuation amplitude σ8, going beyond the linear biasing model to reach the level of accuracy demanded by current and future measurements. We adopt the halo occupation distribution (HOD) framework and test its applicability to this problem by examining the effects of replacing satellite galaxies in the halos of a smoothed particle hydrodynamics (SPH) simulation with randomly selected dark matter particles from the same halos. After accounting for the slight differences between the predicted radial profile of dark matter and satellite galaxies, the residual effects of individual subhalos around satellite galaxies and environmental dependence of the HOD at fixed halo mass are 5% in ΔΣ(r) for 0.1 h-1 Mpc < r < 15 h-1 Mpc. We develop an analytic approximation for calculating ΔΣ(r), improving on previous work with more accurate treatments of halo bias and halo exclusion. We demonstrate its accuracy at the few percent level with tests against a suite of populated N-body simulations. We use the analytic model to investigate the dependence of ΔΣ(r) and the galaxy-matter correlation function ξgm(r) on Ωm and σ8, once HOD parameters for a given cosmological model are pinned down by matching ξgg(r). The linear bias prediction that ξgm(r)/ξgg(r) = constant is accurate for r 2 h-1 Mpc but fails at the 30%-50% level on smaller scales. The linear bias prediction that ΔΣ(r) Ωmσ8 breaks down at r < 10 h-1 Mpc. We present predictions of ΔΣ(r) for SDSS galaxy samples with Mr ≤ - 20 and -21. These can be combined with future lensing measurements for these samples to constrain Ωm and σ8.

description: The remote sensing of gases in complex mixtures at atmospheric pressure is a challenging problem and much attention has been paid to it. The most fundamental difference between this application and highly successful astrophysical and upper atmospheric remote sensing is the line width associated with atmospheric pressure broadening, ~ 5 GHz in all spectral regions. In this paper, we discuss quantitatively a new approach that would use a short pulse infrared laser to modulate the submillimeter/terahertz (SMM/THz) spectral absorptions on the time scale of atmospheric relaxation. We show that such a scheme has three important attributes: (1) The time resolved pump makes it possible and efficient to separate signal from atmospheric and system clutter, thereby gaining as much as a factor of 10^6 in sensitivity, (2) The 3-D information matrix (infrared pump laser frequency, SMM/THz probe frequency, and time resolved SMM/THz relaxation) can provide orders of magnitude greater specificity than a sensor that uses only one of these three dimensions, and (3) The congested and relatively weak spectra associated with large molecules can actually be an asset because the usually deleterious effect of their overlapping spectra can be used to increase signal strength.

This vision was motivated in part by Jacobson's 1995 surprise result that the Einstein equations of gravity follow from the thermodynamic properties of event horizons. Taking a first tentative step in such a program, we derive the evaporation rate (or radiation spectrum) from black hole event horizons in a spacetime-free manner. Our result relies on a Hilbert space description of black hole evaporation, symmetries therein which follow from the inherent high dimensionality of black holes, global conservation of the no-hair quantities, and the existence of Penrose processes. Our analysis is not wedded to standard general relativity and so should apply to extended gravity theories where we find that the black hole area must be replaced by some other property in any generalized area theorem.

description: This study identified and examined the correlates of specific motivations for caregiving in romantic couples (N = 194 couples). At Time 1, couple members completed measures assessing motivations for caregiving, the quality of caregiving that occurs in the relationship, and personal and relationship characteristics that might influence caregiving motivations. Relationship functioning was then assessed 2 to 3 months later. Results revealed that (a) there are a number of distinct motivations for providing and for not providing care to one's partner, (b) the motivations are associated with various personal features of the caregiver and the recipient, (c) the caregiver's perceptions of the relationship influence his or her caregiving motives, (d) different motivations for caregiving predict different patterns of caregiving behavior, and (e) responsive caregiving predicts the recipient's perceptions of healthy relationship functioning both immediately and over time. Implications of identifying the motivations that promote or inhibit the provision of responsive support in intimate relationships are discussed.

description: We report the direct visualization at the scale of single particles of mass transport between smectic layers, also called permeation, in a suspension of rod-like viruses. Self-diffusion takes place preferentially in the direction normal to the smectic layers, and occurs by quasi-quantized steps of one rod length. The diffusion rate corresponds with the rate calculated from the diffusion in the nematic state with a lamellar periodic ordering potential that is obtained experimentally.

description: Perfect transfer of a quantum state through a one-dimensional chain is now well understood, allowing one not only to decide whether a fixed Hamiltonian achieves perfect transfer, but to design a suitable one. We are particularly interested in being able to design, or understand the limitations imposed upon, Hamiltonians subject to various naturally arising constraints such as a limited coupling topology with low connectivity (specified by a graph) and type of interaction. In this paper, we characterise the necessary and sufficient conditions for transfer through a network, and describe some natural consequences such as the impossibility of routing between many different recipients for a large class of Hamiltonians, and the limitations on transfer rate. We also consider some of the trade-offs that arise in uniformly coupled networks (both Heisenberg and XX models) between transfer distance and the size of the network as a consequence of the derived conditions.

description: Corpora of child language are essential for research in child language acquisition and psycholinguistics. Linguistic annotation of the corpora provides researchers with better means for exploring the development of grammatical constructions and their usage. We describe a project whose goal is to annotate the English section of the CHILDES database with grammatical relations in the form of labeled dependency structures. We have produced a corpus of over 18,800 utterances (approximately 65,000 words) with manually curated gold-standard grammatical relation annotations. Using this corpus, we have developed a highly accurate data-driven parser for the English CHILDES data, which we used to automatically annotate the remainder of the English section of CHILDES. We have also extended the parser to Spanish, and are currently working on supporting more languages. The parser and the manually and automatically annotated data are freely available for research purposes.

description: We show that any closed hyperbolic $3$-manifold $M$ has a co-final tower of covers $M_i \to M$ of degrees $n_i$ such that any subgroup of $π_1(M_i)$ generated by $k_i$ elements is free, where $k_i \ge n_i^C$ and $C = C(M) > 0$. Together with this result we show that $\log k_i \geq C_1 sys_1(M_i)$, where $sys_1(M_i)$ denotes the systole of $M_i$, thus providing a large set of new examples for a conjecture of Gromov. In the second theorem $C_1> 0$ is an absolute constant. We also consider a generalization of these results to non-compact finite volume hyperbolic $3$-manifolds.

description: By means of ab-initio calculations in conjunction with the random-phase approximation (RPA) within the full-potential linearized augmented plane wave method we study the screening of the Coulomb interaction in NbxCo (1<=x<=9) clusters. In addition, these results are compared with pure bcc Nb bulk. We find that for all clusters the onsite Coulomb interaction in RPA is strongly screened whereas the inter-site non-local Coulomb interaction is weakly screened and for some clusters it is unscreened or even anti-screened. This is in strong contrast with pure Nb bulk, where the inter-site Coulomb interaction is almost completely screened. Further, constrained RPA calculations reveal that the contribution of the Co 3d ! 3d channel to the total screening of the Co 3d electrons is small. Moreover, we find that both the onsite and inter-site Coulomb interaction parameters decrease in a reasonable approximation linearly with the cluster size and for clusters having more than 20 Nb atoms a transition from 0D to 3D screening is expected to take place.

description: Αντικείμενο της παρούσας εργασίας είναι ο καθορισμός ενεργειακής πολιτικής σε έξυπνα κτίρια. Στόχος είναι η λήψη αποφάσεων σε ποικίλα ζητήματα στα οποία υπάρχει σύγκρουση πολιτικών μεταξύ των προτεραιοτήτων διαφορετικών χρηστών και ρόλων. Μέσω αυτών των πολιτικών αυτοματοποιείται η διαδικασία λήψης αποφάσεων και ταυτόχρονα επιτυγχάνεται αυξημένη ενεργειακή αλλά και οικονομική αποδοτικότητα. Για την υλοποίηση της εργασίας γίνεται χρήση αισθητήρων IoT (Internet of Thing) για την λήψη αναγκαίων μετρήσεων και δεδομένων των οποίων η διασύνδεση γίνεται μέσω του προτύπου KNX. Επιπλέον η μοντελοποίηση του κτιρίου γίνεται μέσω της εφαρμογής Open Studio/Energy plus. Για την επεξεργασία των δεδομένων και την λήψη απόφασης χρησιμοποιείται ένα εργαλείο ιεραρχικής επιχειρηματολογίας, ο Gorgias. Η μελέτη περίπτωσης γίνεται για το κτίριο των Μηχανικών Περιβάλλοντος του Πολυτεχνείου Κρήτης όπου υπάρχουν τοποθετημένοι κατάλληλοι αισθητήρες για την μέτρηση βασικών παραμέτρων-δεδομένων, όπως θερμοκρασίας, φωτισμού και επιπέδων διοξειδίου του άνθρακα. Για την μελέτη περίπτωσης χρησιμοποιούνται ως παραδείγματα διάφορες καταστάσεις, οι οποίες δεν ήταν δυνατόν να επιλυθούν αποτελεσματικά με την χρήση υφιστάμενων εργαλείων και προγραμμάτων. Το αποτέλεσμα της εργασίας είναι η διαμόρφωση ενεργειακών πολιτικών που βοηθούν στην μείωση της κατανάλωσης ενέργειας καθώς και η αποτελεσματική διαχείριση καταστάσεων όπου υπάρχει σύγκρουση αποφάσεων.
description: The objective is to define and apply energy polices into smart buildings. The goal is to make decisions on a variety of issues where there is a conflict of policies between the priorities of different users and roles. Through these policies, the decision-making process is automated and at the same time increased energy and economic efficiency is achieved. For the implementation of the work, IoT (Internet of Things) sensors are used to take the necessary measurements and data which are interconnected through the KNX standard. The relevant building’s energy consumption data is imported by Open Studio/Energy plus application. A tool for hierarchical argumentation, Gorgias, is used to process the data and make decisions. The case study is applied on the building of Environmental Engineers of the Technical University of Crete where there are suitable sensors for measuring basic parameters-data, such as temperature, lightings and CO2 levels. Various situations are used as case studies, which could not be solved efficiently by using existing tools and software. The result of the work is the implementation of energy policies that help to reduce energy consumption as well as the effective management of situations where there is a conflict of decisions.

description: Let $M$ be a 3-connected matroid, and let $N$ be a 3-connected minor of $M$. A pair $\{x_1,x_2\} \subseteq E(M)$ is $N$-detachable if one of the matroids $M/x_1/x_2$ or $M \backslash x_1 \backslash x_2$ is both 3-connected and has an $N$-minor. This is the third and final paper in a series where we prove that if $|E(M)|-|E(N)| \ge 10$, then either $M$ has an $N$-detachable pair after possibly performing a single $Δ$-$Y$ or $Y$-$Δ$ exchange, or $M$ is essentially $N$ with a spike attached. Moreover, we describe the additional structures that arise if we require only that $|E(M)|-|E(N)| \ge 5$.

description: Phase diagram of Np-U-Zr, a key ternary alloy system of relevance for metallic nuclear fuels, is still largely undetermined. Here a thermodynamic model for the Np-U-Zr system is developed based on Muggianu extrapolation of our models for the U-Zr, Np-Zr, and Np-U binary systems, all employing the CALculation of PHAse Diagrams (CALPHAD) method. This model reproduces available experimental data for the high temperature phases reasonably well, but is uncertain for the lower temperature phases for which experimental data are scarce. Ab initio calculations are performed on the BCC phase of the Np-U-Zr system at 28 compositions employing density functional theory (DFT) both in its standard form and the so-called DFT plus Hubbard U (DFT + U) modification. When referencing to our CALPHAD model, standard DFT on average overestimates the enthalpy of mixing of the BCC phase by 0.093 eV/atom, while DFT + U reduces the error to 0.009-0.036 eV/atom when the effective Hubbard U parameters are in the ranges of single-structure optimized Ueff's determined in our previous studies of the Np-Zr and U-Zr systems (0.65-0.90 for Ueff(Np) and 0.99-1.49 eV for Ueff(U), respectively). Our combined CALPHAD and ab initio modeling provides an initial attempt to determine the phase diagram of the Np-U-Zr system but further work is needed for a reliable determination.
