description: This study examined the degree to which emotions and/or rational thinking should be emphasized to improve performance in target detection in complex tasks. Specifically, we evaluated the dual-process model of decision making to determine whether emotion or cognition (or a combination of the two) is more powerful in influencing decisions. Additionally, we considered how decisions are influenced with the addition of an automated agent to assist human decision making. Participants (n = 120) were randomly assigned to one of three framing manipulations, each with positive and negative incentives: the analytical frame emphasized numerical gains or losses; the affective frame presented gains and losses as "lives saved" and "lives lost"; the comparative frame emphasized better or worse performance relative to one's peers. Performance was assessed both with and without the assistance of an automated decision aid in a simulated airline luggage screening task. Performance was measured by hit rates and false alarm rates; human-automation interaction was assessed via compliance, reliance and system trust. Results revealed that participants in the analytical frame were able to balance their hits and false alarms whereas the affective and comparative frames were unable to achieve this balance. Although the affective frame generated several hits, they also generated a large proportion of false alarms; they were strongly influenced by the negative incentive of "lives lost" and complied frequently with automation, even in instances when the automation was possibly incorrect. Results imply that in contexts such as security screening, emphasizing analytical thinking enables operators to perform effectively and utilize automation appropriately. However, emphasis on affective thought hinders the ability to weigh outcome probabilities and leads to inappropriate automation dependence. The findings have implications for both operator training and automation design in complex tasks.
Dynamic Mode Decomposition For Improved Numerical Stability of Finite Volume Simulations

Publisher: name: AIAA
Year: 2024

description: We propose a novel approach to mesh optimization for improved stability of finite-volume simulations using dynamic mode decomposition on a subset of the solution vectors. A minimal number of the most recent solution vectors in the simulation are selected for dynamic mode decomposition. The eigenvalues of the Koopman matrix depict the magnitude growth rate and oscillation frequency of the largest solution modes. The computational cost of this method depends on the number of solution vectors in use, which is considerably less expensive compared to the eigenanalysis of the full Jacobian matrix. The dynamic eigenvectors are utilized to identify which control volumes and vertices have the greatest impact on each dynamic solution mode. The gradients of the Jacobian matrix diagonal are calculated with respect to the movement of the selected vertices. The positions of these points are adjusted to increase the diagonal dominance of the Jacobian matrix on the corresponding rows. The results verify the effectiveness and feasibility of the novel approach in numerical stability improvement through unstructured mesh optimization. This state-of-the-art method addresses the challenges faced by the latest studies in this field with full automation of the mesh optimization process and substantial computational savings.

description: This paper analyzes the use of bootstrap methods to discern the statistical precision of consumer welfare estimates from recreation demand models. Results suggest that a great deal of imprecision is present in estimates from typical cross-section data. Precision can be improved through imposition of inequality constraints on the demand function parameters.

description: The aim of this thesis to present a novel framework that enables intelligent compromise between competing requirements for performance, protection and comfort in cricket batting personal protective equipment (PPE). The proposed framework uses information collected from the Internet of Things (IoT) technologies in cricket and demonstrates its future potential in improving player safety. The literature presented in this thesis shows that the current commercially available cricket batting PPE are suboptimal in addressing competing demands for batter performance, protection and comfort. Therefore, a novel smart PPE framework with two critical subsystems: an active decision-making subsystem and a state-change enabled protective response system are suggested in this study to enable intelligent protection. The thesis outlines and evaluates a potential active decision-making system based on data harvested from body-worn Inertial Measuring Units (IMU). [Continues.]

description: We report an experimental and theoretical study of the phase diffusion in small Josephson junctions under microwave irradiation. A peculiar enhancement of the phase diffusion by microwaves is observed. The enhancement manifests itself by a pronounced current peak in the current-voltage characteristics. The voltage position $V_{\rm top}$ of the peak increases with the power $P$ of microwave radiation as $V_{\rm top}\propto\sqrt P$, while its current amplitude weakly decreases with $P$. As the microwave frequency increases, the peak feature evolves into Shapiro steps with finite slope. Our theoretical analysis taking into account the enhancement of incoherent superconducting current by multi-photon absorption is in good agreement with experimental data.

description: The pp-wave/SYM correspondence is an equivalence relation, H_{string}= Delta -J, between the Hamiltonian H_{string} of string field theory in the pp-wave background and the dilatation operator Delta in N=4 Super Yang-Mills in the double scaling limit. We calculate matrix elements of these operators in string field theory and in gauge theory.In the string theory Hilbert space we use the natural string basis,and in the gauge theory we use the basis which is isomorphic to it. States in this basis are specific linear combinations of the original BMN operators, and were constructed previously for the case of two scalar impurities. We extend this construction to incorporate BMN operators with vector and mixed impurities. This enables us to verify from the gauge theory perspective two key properties of the three-string interaction vertex of Spradlin and Volovich: (1) the vanishing of the three-string amplitude for string states with one vector and one scalar impurity; and (2) the relative minus sign in the string amplitude involving states with two vector impurities compared to that with two scalar impurities. This implies a spontaneous breaking of the Z_2 symmetry of the string field theory in the pp-wave background. Furthermore, we calculate the gauge theory matrix elements of Delta -J for states with an arbitrary number of scalar impurities. In all cases we find perfect agreement with the corresponding string amplitudes derived from the three-string vertex.

description: Agricultural observers are keenly interested in tracking the response of New Zealand's agricultural sector to Government's "economic liberalisation" policies. These 1984 reforms removed direct and indirect Governmental assistance to agriculture· as part of a general industries policy relating to competition, taxation, marketing and risk bearing. The abrupt change in policy orientation has had severe repercussions, with differential sectoral abilities to respond. Adjustment processes have been frustrated by adverse climatic events (Cyclone Bola and drought), as well as slower than anticipated "desirable" changes in key macroeconomic variables - continuing high interest and exchange rates. Key reforms to further remove public sector involvement from agriculture include privatisation of The Rural Bank and sale of the Government's holdings in irrigation schemes. Total farm debt has increased by nearly two and a half fold since 1980 (from NZ$3.5 billion to NZ$8.5 billion). Over the same period gross agricultural production increased by only 70 percent from NX$4.4 billion to NZ$7.6 billion. Agriculture's contribution to Gross Domestic Product increased more slowly (from NZ$2.1 billion to NZ$3.3 billion) and its relative share of GDP has fallen from 10.8 to 5.9 percent. Land values, which had quadrupled in the 1970's, continued to rise through 1982 and have fallen substantially in the decapitalisation process in response to more market related prices in the pastoral sector. The speed of the adjustment process is dampened by excessive debt service requirements for many operating units, limited open recognition for significant structural adjustment and plodding financial sector progress towards needed debt restructuring.

description: In addition to the common 3-body decay of the neutron $n\rightarrow p e^-\overline{ν_e}$ there should exist an effective 2-body subset with the electron and proton forming a Hydrogen bound state with well defined total momentum, total spin and magnetic quantum numbers. The atomic spectroscopic analysis of this bound system can reveal details about the underlying weak interaction as it mirrors the helicity distributions of all outgoing particles. Thus, it is unique in the information it carries, and an experiment unravelling this information is an analogue to the Goldhaber experiment performed more than 60 years ago. The proposed experiment will search for monoenergetic metastable BoB H atoms with 326 eV kinetic energy, which are generated at the center of a throughgoing beamtube of a high-flux reactor (e.g., at the PIK reactor, Gatchina). Although full spectroscopic information is needed to possibly reveal new physics our first aim is to prove the occurrence of this decay and learn about backgrounds. Key to the detection is the identification of a monoerergtic line of hydrogen atoms occurring at a rate of about 1 $\rm{s}^{-1}$ in the environment of many hydrogen atoms, however having a thermal distribution of about room temperature. Two scenarios for velocity (energy) filtering are discussed in this paper. The first builds on an purely electric chopper system, in which metastable hydrogen atoms are quenched to their ground state and thus remain mostly undetectable. This chopper system employs fast switchable Bradbury Nielsen gates. The second method exploits a strongly energy dependent charge exchange process of metastable hydrogen picking up an electron while traversing an argon filled gas cell, turning it into manipulable charged hydrogen. The final detection of hydrogen occurs through multichannel plate (MCP) detector.

description: In this work, the exact reproduction of a moving-water steady flow via the numerical solution of the one-dimensional shallow water equations is studied. A new scheme based on a modified version of the HLLEM approximate Riemann solver [Dumbser M. and Balsara D.S., J. Comput. Phys. 304 (2016) 275--319] that exactly preserves the total head and the discharge in the simulation of smooth steady flows and that correctly dissipates mechanical energy in the presence of hydraulic jumps is presented. This model is compared with a selected set of schemes from the literature, including models that exactly preserve quiescent flows and models that exactly preserve moving-water steady flows. The comparison highlights the strengths and weaknesses of the different approaches. In particular, the results show that the increase in accuracy in the steady-state reproduction is counterbalanced by a reduced robustness and numerical efficiency of the models. Some solutions to reduce these drawbacks, at the cost of increased algorithm complexity, are presented.

description: We have discovered a new type of scalarized charged black holes in a surprisingly simple system: an Einstein-Maxwell-Klein-Gordon field theory where the three fields couple non-minimally through a Horndeski vector-tensor term. In addition to hairy charged black holes, this system exhibits Horndeski-Reissner-Nordstrom solutions and ordinary Reissner-Nordstrom ones which bifurcate to the scalarized solutions. There exist also vector-tensor black hole solutions which possess central curvature singularities although their metric components are finite there, and also solutions with naked singularities producing regular metric components everywhere around them. We analyze the solutions and present their main features.

Figure 12
Stations: Kanacono DW 4717; DW 4717; DW 4730. Six specimens.
The body is elongated in all specimens with a brown leathery tunic harder posteriorly where it makes a kind of peduncle (Fig. 12A). The oral siphon is apical slightly turned outward, the atrial siphon is somewhat posterior protruding a short distance away from the oral siphon. Removed from the tunic the body appears in two parts (Fig. 12B) the major one anterior containing the main organs and a posterior bulbous segment filled with body wall tissue. There are numerous long oral tentacles. The dorsal tubercle opens anteriorly in a U and located in a deep V of the prepharyngeal band. The 4 branchial folds per side are well separated (FIG. 12D). One formula on the right side is: E- 4(13)4(20)4(20)4(15)1-DL
Parastigmatic vessels are present. The branchial sac does not penetrate into the posterior segment of the body. The digestive loop vertically oriented (Fig. 12C) is loosely attached to the body wall. The olive-shaped stomach has internal longitudinal ridges. The anus rim in two lips is fringed with a series of long lobes. The gonads are numerous (Fig. 12C), about 16 on each side, distributed without precise design. Each polycarp contains an ovary sided by a row of testis vesicles; the genital papillae are joined and short. A large surface of the body wall wears endocarps, including some present inside the gut loop. No velum or tentacles have been found at the atrial aperture.
 The present specimens correspond to those described from Indonesia in Monniot & Monniot (2001). They differ from Polycarpa reviviscens Monniot & Monniot, 2001 which has the same posterior body extension but the zooids are aggregated in clumps and have polycarps of different shape.
 Polycarpa producta Monniot & Monniot, 2003 from the Caledonian basin is very similar in shape to P. papillata described above but differs by more numerous endocarps and less polycarps arranged in a line.

Modeling Fluctuations in the GRB-Afterglow Light Curves

description: The fluctuations observed in the light curves of some GRB-afterglows (such as GRB 021004) provide a useful tool to probe the circum-burst density profile and to probe the variations in the energy of blast-wave with time. We present a general formalism that reduces the calculation of the observed light curve from a Blandford-Mackee blast-wave to the evaluation of a one dimensional integral. Using this formalism we obtain a simple approximation to the general light curve that arises in more complex situations where the afterglow's energy or the external density vary. The solution is valid for spherically symmetric profiles and it takes a full consideration of the angular time delay effects. We present the light curves of several external density profiles and demonstrate the effects of density variations on the light curve. We also re-visit the afterglow of GRB021004 and we find that the steep decay after the first bump ($\sim 4000sec$) cannot result from a spherically symmetric density variation or from the passage of the synchrotron frequency through the optical band. This suggests that an angular structure is responsible to some of the observed features in the light curve. This may be the first evidence that an angular structure is important in the early stages of the afterglow.

Approximate Jacobian Eigenanalysis For Unstructured Mesh Optimization of Finite-Volume Simulations
Creators: name: Zandsalimy, Mohammad
name: Ollivier-Gooch, Carl
Publisher: name: AIAA
Year: 2024

description: This paper presents a novel method for approximate eigenanalysis of large linear systems, with a specific focus on unstable eigenvalues in the Lyapunov sense. The method utilizes residual vector analysis, principal component analysis, and dynamic mode decomposition to identify unstable solution modes efficiently. Outlier detection models are employed to find the problematic cells on the unstructured mesh in the case of residual vector and principal component analysis while the dynamic mode decomposition points directly to the control volumes of interest without such help. By extracting and assembling corresponding rows of the Jacobian matrix, the large system is projected on a new matrix with significantly fewer degrees of freedom, leading to improved computational efficiency. The eigenvalue problem is then solved on this smaller matrix, and the obtained results are utilized for mesh optimization, enhancing the local stability of the dynamic system. By addressing the challenges of computational complexity and automation faced by previous methods, this novel approach offers a comprehensive and automated solution for the eigenanalysis of large linear systems. The potential impact of this method extends to various fields, providing a more efficient eigenanalysis process and opening new avenues for exploring and optimizing complex systems.

Statistic difference was not found between the number of plaqueforming units (PFU) of reconstituted vaccine associated with both antibiotics 0, 15, 30 and 60 minutes after reconstitution of vaccine. The antibiotics did not considerably alter the pH values. There was a significative decrease of the titer of all vaccinal solutions when they were inoculated 30 and 60 minutes after the reconstitution of the vaccine. Nevertheless, these titers are higher than the required titers to protectect against the Marek disease.

REMARK
To accommodate the Lamarckian species Asterias ocellifera, Gray (1840) established the genus Nectria. Yet Gray had not seen Lamarck’s type specimens of A. ocellifera. When working on asteroids of the genus Nectria housed in the British Museum, Perrier (1875) realised that the species N. ocellifera sensu Gray was different from the species described by Lamarck while sharing some similarities with the second Paris specimen also identified as A. ocellifera by Lamarck. He consequently proposed the new name Nectria ocellat a for Gray’s specimens and gave a precise description of one of the Gray’s individuals that will be considered later as the lectotype of the species (Zeidler & Rowe 1986). As a consequence, the second specimen of Lamarck, while collected by Péron and Lesueur and being representative of the Perrier’s species, is not a type of Nectria ocellata Perrier, 1875.

description: Deliverable D6.9 “Final report on the contribution to standardization” is produced in the context of SunCOChem WP6, Task 6.3 “Standardisation activities”, in particular with regard to the subtask 6.3.2 “Contribution to the ongoing and future standardization developments”. This deliverable includes a summary of all standardization-related activities performed during the project, with a special focus on the contribution to new standards, performed since M24 to M54.

The transfer of SunCOChem results to standards being widely recognized by the industry and published by independent standardization organizations, external to the consortium, is a way to increase the impact of the project results beyond its duration. Additionally, the standardization system is used as a targeted dissemination channel towards the stakeholders represented in the standardization committees.

Main standardization activities in the project have been the following:

Identification of existing standards and related standardization organizations and technical committees (reported in D6.2).

Elaboration of a strategy for the SunCOChem contribution to standardization.

Contacts with potentially interested standardization technical committees in CEN and ISO (reported in D6.5).

Analysis of the standardization potential of project outcomes and possible tracks, and selection of the most promising.

Standardization process for elaboration of a new standardization document in CEN.

The main outcome of this project activity has been the publication by the European Standards Organization CEN of CWA 18147:2024 “Testing and evaluating the performance of electrolysers for reduction of CO2 to CO”, proposed and led by SunCOChem partners, based on the outcomes of the project.

description: We demonstrate an unsuspected freedom in physics, by showing an essential unpredictability in the relation between the behavior of clocks on the workbench and explanations of that behavior written in symbols on the blackboard. In theory, time and space are defined by clocks synchronized as specified by relations among clock readings at the transmission and reception of light signals; however spacetime curvature implies obstacles to this synchronization. Recognizing the need to handle bits and other symbols in both theory and experiment, we offer a novel theory of symbol handling, centered on a kind of "logical synchronization," distinct from the synchronization defined by Einstein in special relativity. We present three things: (1) We show a need in physics, stemming from general relativity, for physicists to make choices about what clocks to synchronize with what other clocks. (2) To exploit the capacity to make choices of synchronization, we provide a theory in which to express timing relations between transmitted symbols and the clock readings of the agent that receives them, without relying on any global concept of "time". Dispensing with a global time variable is a marked departure from current practice. (3) The recognition of unpredictability calls for more attention to behavior on the workbench of experiment relative to what can be predicted on the blackboard. As a prime example, we report on the "horse race" situation of an agent measuring the order of arrival of two symbols, to show how order determinations depart from any possible assignment of values of a time variable.

description: The trend over the past four decades to move manufacturing operations to low-wage countries has left many developed nations with diminished manufacturing skills. Manufacturing’s current trajectory appears aimed at automating away human roles in tasks requiring cognitive skills much as it has automated away human roles in tasks requiring physical skills. This may prove difficult owing to the diversity of industrial contexts and skills involved in manufacturing. It may be possible, however, for humans to perform some cognitive tasks (such as production scheduling) jointly with artificial intelligence (AI) machine agents. This thesis reports the research undertaken to improve outcomes in the cognitive task of formulating production scheduling solutions. The aim is to develop an effective methodology by which the work of production scheduling can be divided among human and machine agents, then to develop tools to support the methodology. Requirements on joint cognitive work were established through a detailed literature review and an industrial pilot. These efforts revealed that, though machine guidance and validation of analysts’ scheduling solutions is theoretically possible, research gaps make this joint cognitive work impractical. Specifically, difficulties are encountered in: (1) analysts translating requirements into analytical models; (2) machine agents recognizing the scheduling formulation analysts are attempting; and (3) both analysts and machine agents staying apprised of emerging impediments to production. Analysis of the requirements and research gaps pointed to the development of a sociotechnical system in which the joint work is performed as the manipulation of two shared objects: a notebook for formulating the scheduling problem, and computer simulations highlighting current production challenges. Methodology and software were developed to support the shared objects and to validate their use in addressing the research gaps.

description: We consider anisotropic diffusion of Galactic cosmic rays in the Galactic magnetic field, using the Jansson-Farrar model for the field. In this paper we investigate the influence of source position on the cosmic ray flux at Earth in two ways: [1] by considering the contribution from cosmic ray sources located in different intervals in Galacto-centric radius, and [2] by considering the contribution from a number of specific and individual close-by supernova remnants. Our calculation is performed by using a fully three-dimensional stochastic method. This method is based on the numerical solution of a set of stochastic differential equations, equivalent to Ito formulation, that describes the propagation of the Galactic cosmic rays.

description: We study numerically the ODE/IM correspondence for untwisted affine Lie algebras associated with simple Lie algebras including exceptional type. We consider the linear problem obtained from the massless limit of that of the modified affine Toda field equation. We found that the Q-functions in integrable models are expressed as the inner product of the solution of the dual linear problem and the subdominant solution of the linear problem. Using Cheng's algorithm to obtain the solution of the linear problem, we can determine efficiently the zeros of the Q-function, which is known to provide the solutions of the Bethe ansatz equations. We calculate the zeros numerically, which are shown to agree with the results from the Non-Linear Integral Equations for simply-laced affine Lie algebras including the exceptional type. By the folding procedure of the Dynkin diagrams of simply-laced Lie algebras, we also find the correspondence for the linear problem of the non-simply-laced affine Lie algebras.

Order parameter for the multichannel Kondo model at quantum criticality

description: A multichannel Kondo model, where two or more equivalent but independent channels of electrons compete to screen a spin-1/2 impurity, shows overcompensation of the impurity spin, leading to the non-Fermi-liquid behavior in various thermodynamic and transport properties. However, when the channel symmetry is broken, an impurity quantum phase transition can occur at zero temperature. Identification of an order parameter describing the impurity quantum phase transition is very difficult since it is beyond the conventional Landau-Ginzburg-Wilson theory. By employing the natural orbitals renormalization group method, we study both two-channel and threechannel Kondo models, from the perspective of spin correlation between the impurity and electrons in electronic channels. Here we demonstrate that by introducing the spin-correlation ratio as an order parameter we can characterize impurity quantum phase transitions driven by channel asymmetry. In particular, the universal critical exponents $β$ of the spin-correlation ratio and $ν$ of the correlation length are explicitly determined by finite-sizescaling analysis, namely, $β= 0.10(1), ν= 2.0(1)$, and $β= 0.10(1), ν= 2.5(1)$ for the two-channel and three-channel Kondo models, respectively.

description: A general form for all supersymmetric solutions of minimal supergravity in six dimensions is obtained. Examples of new supersymmetric solutions are presented. It is proven that the only maximally supersymmetric solutions are flat space, AdS_3 x S^3 and a plane wave. As an application of the general solution, it is shown that any supersymmetric solution with a compact horizon must have near-horizon geometry R^{1,1} x T^4, R^{1,1} x K3 or identified AdS_3 x S^3.

description: We present a new task of query auto-completion for estimating instance probabilities. We complete a user query prefix conditioned upon an image. Given the complete query, we fine tune a BERT embedding for estimating probabilities of a broad set of instances. The resulting instance probabilities are used for selection while being agnostic to the segmentation or attention mechanism. Our results demonstrate that auto-completion using both language and vision performs better than using only language, and that fine tuning a BERT embedding allows to efficiently rank instances in the image. In the spirit of reproducible research we make our data, models, and code available.

description: Automatically learning thematic clusters in network data has long been a challenging task in machine learning community. A number of approaches have been proposed to accomplish it, utilizing edges, vertex features, or both aforementioned. However, few of them consider how the quantification of dichotomous inclination w.r.t. network topology and vertex features may influence vertex-cluster preferences, which deters previous methods from uncovering more interpretable latent groups in network data. To fill this void, we propose a novel probabilistic model, dubbed Relational Thematic Clustering with Mutually Preferred Neighbors (RTCMPN). Different from prevalent approaches which predetermine the learning significance of edge structure and vertex features, RTCMPN can further learn the latent preferences indicating which neighboring vertices are more possible to be in the same cluster, and the dichotomous inclinations describing how relative significance w.r.t. edge structure and vertex features may impact the association between pairwise vertices. Therefore, cluster structure implanted with edge structure, vertex features, neighboring preferences, and vertex-vertex dichotomous inclinations can be learned by RTCMPN. We additionally derive an effective Expectation-Maximization algorithm for RTCMPN to infer the optimal model parameters. RTCMPN has been compared with several strong baselines on various network data. The remarkable results validate the effectiveness of RTCMPN.
Borderline vulnerabilities: an institutional ethnography of the asylum process in Lesbos, Greece

description: This dissertation is an exploration of vulnerability-based decision- making in the context of the implementation of asylum procedures at EU’s south eastern borders. I contend that EU’s borders must be examined in relation to the regulation of cross border mobility and must be understood as a set of social and temporal processes that spatially (re)produce vulnerability. As a case study I present the institutional assessment of vulnerability on the island of Lesbos, following the EU’s recognition of Turkey as a safe third country for asylum seekers in March 2016. I deploy institutional ethnography as a research and methodological tool; I locate myself in Lesbos and Athens to study the assessment of vulnerability in practice, through the daily work and narratives of Greek and EC bureaucrats, medical professionals and lawyers who are responsible for ascribing vulnerability. In addition, I examine legal and bureaucratic documents which produce a particular way of understanding and assessing vulnerability. I demonstrate that vulnerability narratives are directly associated with regulatory frameworks, norms and practices which administrate people in space and time. In particular, it is through the affirmation and/or denial of vulnerability during the asylum process that individuals come to be assessed as deserving international protection and welfare provision. In this way, individuals crossing the EU-Turkish border are ‘managed’ not only through the credibility of their asylum claim but on additional medical and moral grounds. Against this categorical and a-spatial understanding of vulnerability, I propose a geographical approach that takes into account the place specificity of migrants’ embodied experience, precarity and trauma as a way of advancing critical geographies of border and immigration controls.
