title: The relationship between emotional arousal and cognition
Creators: name: Turkileri, Nilgun
Publisher: name: University of Reading
Year: 2019

description: The interaction between emotion and cognition is pivotal for everyday functioning. Emotional scenes, such as a crime scene in a movie, would grab more attention than a neutral scene, such as a car passing by. Besides, we mostly remember personal events that have an emotional significance, such as the first day of the college. On the other hand, some other emotional events, for instance traumatic experiences, can sometimes be recalled frequently and involuntarily or completely suppressed. This thesis explores these opposing effects of emotional arousal. The first and second studies utilise a memory-guided attention paradigm to investigate emotional enhancement and impairment effects on attention to the scene pictures known by prior knowledge. The results showed that attention to a target location in the scenes previously known was boosted by emotional arousal induced by an anticipation of a fearful shock into the participant’s finger. On the other hand, attention to a target location that was not known beforehand was not affected by the fear of shock. The third and the last study investigated how emotional arousal induced by negative sound clips would affect ambiguous motion perception. Here participants were able to choose a dominant (i.e., leftward or rightward) direction when they felt emotionally aroused by listening a negative sound clip. These studies underline the complex relationship of emotional arousal and cognition. Emotional arousal helps to boost attention, memory, and perception to something important for the individual whether it comes from past memories or it dominates by perception. Critical evaluations have been included in the experimental chapters while the general discussion draws a broader conclusion in the interaction between emotion and cognition and discusses some implications.
Mott insulator to superfluid transition in the Bose-Hubbard model: a strong-coupling approach

description: We present a strong-coupling expansion of the Bose-Hubbard model which describes both the superfluid and the Mott phases of ultracold bosonic atoms in an optical lattice. By performing two successive Hubbard-Stratonovich transformations of the intersite hopping term, we derive an effective action which provides a suitable starting point to study the strong-coupling limit of the Bose-Hubbard model. This action can be analyzed by taking into account Gaussian fluctuations about the mean-field approximation as in the Bogoliubov theory of the weakly interacting Bose gas. In the Mott phase, we reproduce results of previous mean-field theories and also calculate the momentum distribution function. In the superfluid phase, we find a gapless spectrum and compare our results with the Bogoliubov theory.

description: In this letter, we simulate electronic transport through a metal-ferroelectric-metal tunnel junction by use of a nonequilibrium Green's function approach. We show that quantum effects such as Friedel oscillations lead to deviations from the Thomas-Fermi screening model. As a consequence, we predict a bistable resistive switching effect, depending on the polarization state of the ferroelectric tunnel barrier.
Foreign direct investment dynamics in the face of the informal economy and corruption - Theory and new empirical findings
Creators: name: Zander, Tobias
Publisher: name: Bergische Universität Wuppertal
Year: 2023

description: The underlying dissertation analyses the effect of corruption and the informal economy on regional and global investment dynamics. Relevant theory is evaluated and gravity models are applied to show the above-mentioned effects on foreign direct investments (FDI). In the first empirical analysis, the author shows that an increase in a country's corruption levels increases the FDI flows said country receives. For the origin countries of FDI, the effect is reversed. Lower levels of corruption are associated with higher levels of FDI flows, which could result from the origin countries usually being richer countries, and richer countries often have lower levels of corruption and a better rule of law. The second and third analysis focuses on the informal economy. Here, the author shows that countries with a bigger informal economy receive more FDI suggesting that multinational companies (MNCs) take advantage of characteristics of the informal economy of a target country of FDI, e.g., lower labor costs though subcontracting to an enterprise active in the informal economy. Additionally, through an interaction term, the author can show that an increase in government size increases the effect that the informal economy has on FDI inflows. These findings are robust over several specifications and datasets. All three analyses show that MNCs can and will take advantage of corruption and the informal economy in order to maximize their profits.

description: Density functional theory calculations are performed to probe reaction pathways of N2O reduction by CO molecule catalysed over Si-doped C3N (Si-C3N) nanosheets. According to our results, a single Si atom can be stabilised above the C- or N-vacancy site of C3N due to the formation of strong Si-N or Si-C covalent bonds. The reduction of N2O over Si-C3N is characterised as a two-step process. First, N2O is dissociated to N2 and an activated oxygen atom (Oads) without an energy barrier. Then, the Oads moiety is removed by CO molecule by overcoming negligible activation energy.

description: The entry and exit decisions, considered as investment decisions, are investigated in the paper. Taking into account the heterogeneity of entry and exit, the analysis is based on two types of entry-exit: real (related to the establishment or closing of a firm), or entry-exit in a new sector (indicating the diversification or changing specialisation). The theoretical model is based on Marshallian trigger points with Real Option trigger points as an alternative. The estimation exploited the negative binomial model to investigate the role of trigger points (thresholds) on the observed number of entry or exit firms in Dutch glasshouse horticulture over 25 years. Firms should overcome different thresholds depending on types of entry and exit. Marshallian trigger points function as good as the ones based on Real Option theory. The estimation of the model, which takes into account expected output prices, uncertainty and the interest rate, however, provides the best explanation of entry and exit. That model can be considered of a flexible variant of Real Option theory. The model provides plausible elasticities of entry and exit, either real or in changing specialisation.

description: Production and marketing of African Leafy Vegetables (ALVs) has increasingly become important in areas surrounding Nairobi. This is mainly due to Nairobians' realization of their nutritional value. ALVs are particularly rich in mineral nutrients and vitamins that are useful in the management of ailments including HIV/AIDS. In addition, these vegetables remain extremely important for overcoming food insecurity and alleviating poverty among the rural and urban populations as they are relatively affordable. Alongside these private uses, ALVs also have a public value which includes maintenance of traditions and culture, and contribution to sustainable development, specifically in the conservation of biodiversity alongside other ecosystem benefits. Despite this importance, little economic analysis has been conducted to assess how on-farm conservation of ALV biodiversity (intra and interspecific) in areas around Nairobi is affected by market development. It is against this background that this paper addresses the following research questions: 1) which varieties are demanded by the market in Nairobi and for what reasons, and 2) what is the effect of market development on on-farm biodiversity of ALVs around Nairobi? To address these research questions, the study uses empirical data derived using both qualitative and quantitative methods. An econometric model was specified to estimate effect of market development and other determinants of ALV biodiversity levels. Results indicate consumers demand only certain ALVs due to the nutritive aspects associated with them. However, the effect of market development on on-farm diversity of intra and inter-specific ALVs species is mixed. While market development in terms of gross sales has no significant effect, spatial dimension of market development reduces intra-diversity of ALVs. The paper concludes by deriving policy implications on conservation of ALVs on farms surrounding Nairobi and its peri-urban areas.

ü  Gentle compression of the of the chest usually results in the establishment of respiratory effort. Respiratory stimulation should be continued by rubbing the thorax.

ü  The umbilicus should be cut approximately 3 cm from the fetal abdomen. The cord dries up on its own in a few days and the scab drop itself in about a week or a maximum of 10 days. Excessive bleeding can be prevented by the application of a ligature (tying off)

ü  Thermoregulation is poorly developed in young infants and they are unable to produce body heat to warm up. The recommended temperature is 77-86º F for the first few days.

ü  The puppies must always be housed in a warm, dark, and quiet place. Puppies under the age of 3 weeks can be housed in a cardboard box (2-3 feet in length and breadth, at least 11/2 foot high). Puppies of the same litter should be housed together.

ü  Encourage the puppy to suckle. Suckling normally occurs immediately after birth and at intervals of 2 to 3 hours for the first few days. It is important that puppies suck adequately during the first 24 hours of life to ensure absorption of maternal antibodies from the colostrum.

description: China Jinping Underground Laboratory (CJPL) is ideal for studying solar-, geo-, and supernova neutrinos. A precise measurement of the cosmic-ray background would play an essential role in proceeding with the R\&D research for these MeV-scale neutrino experiments. Using a 1-ton prototype detector for the Jinping Neutrino Experiment (JNE), we detected 264 high-energy muon events from a 645.2-day dataset at the first phase of CJPL (CJPL-I), reconstructed their directions, and measured the cosmic-ray muon flux to be $(3.53\pm0.22_{\text{stat.}}\pm0.07_{\text{sys.}})\times10^{-10}$ cm$^{-2}$s$^{-1}$. The observed angular distributions indicate the leakage of cosmic-ray muon background and agree with the simulation accounting for Jinping mountain's terrain. A survey of muon fluxes at different laboratory locations situated under mountains and below mine shaft indicated that the former is generally a factor of $(4\pm2)$ larger than the latter with the same vertical overburden. This study provides a convenient back-of-the-envelope estimation for muon flux of an underground experiment.

description: In 1881, Newcomb conjectured that the first significant digits (FSDs) of numbers in statistical tables would follow a logarithmic distribution with the digit “1” occurring most often. However, because Newcomb’s proposal was not presented with a theoretical basis, it was not given much attention. Fifty-seven years later, Benford argued for the same principle and showed it was relevant to a large range of data sets, and the logarithmic FSD distribution became known as “Benford’s Law.” In the mid-1940s, Stigler claimed Benford’s Law contained a theoretical inconsistency and supplied an alternative derivation for the distribution of FSDs. In this paper, we examine the theoretical basis of the Stigler distribution and extend his reasoning by incorporating FSD first moment information and information-theoretic methods.

description: We present cosmological constraints from a cosmic shear analysis of the fourth data release of the Kilo-Degree Survey (KiDS-1000), doubling the survey area with nine-band optical and near-infrared photometry with respect to previous KiDS analyses. Adopting a spatially flat $Λ$CDM model, we find $S_8 = σ_8 (Ω_{\rm m}/0.3)^{0.5} = 0.759^{+0.024}_{-0.021}$ for our fiducial analysis, which is in $3σ$ tension with the prediction of the Planck Legacy analysis of the cosmic microwave background. We compare our fiducial COSEBIs (Complete Orthogonal Sets of E/B-Integrals) analysis with complementary analyses of the two-point shear correlation function and band power spectra, finding results to be in excellent agreement. We investigate the sensitivity of all three statistics to a number of measurement, astrophysical, and modelling systematics, finding our $S_8$ constraints to be robust and dominated by statistical errors. Our cosmological analysis of different divisions of the data pass the Bayesian internal consistency tests, with the exception of the second tomographic bin. As this bin encompasses low redshift galaxies, carrying insignificant levels of cosmological information, we find that our results are unchanged by the inclusion or exclusion of this sample.

Consequently, the importance of methods that help officials quickly identify human tampering of data cannot be underestimated. In this paper, we suggest Benford’s Law as a basis for objectively identifying the presence of experimenter distortions in the outcome of clinical research data. We test this tool on a clinical data set that contains falsified data and discuss the implications of using this and information-theoretic methods as a basis for identifying data manipulation and fraud.

description: We compute partition functions describing multiplicities and charges of massless and first massive string states of pure-spinor superstrings in 3,4,6,10 dimensions. At the massless level we find a spin-one gauge multiplet of minimal supersymmetry in d dimensions. At the first massive string level we find a massive spin-two multiplet. The result is confirmed by a direct analysis of the BRST cohomology at ghost number one. The central charges of the pure spinor systems are derived in a manifestly SO(d) covariant way confirming that the resulting string theories are critical. A critical string model with N=(2,0) supersymmetry in d=2 is also described.

description: According to the Coase theorem, if property rights to pollute are clearly established and emissions permit markets nearly eliminate transaction costs, the permit market equilibrium will be independent of how the permits are initially distributed among firms. Testing the independence of firms' permit allocations and emissions is difficult because of endogeneity and omitted variable bias. We exploit the random assignment of firms to different permit allocation cycles in Southern California's RECLAIM Program to test for a causal relationship between facility-level emissions and initial permit allocations. Our primary finding is that a null hypothesis of zero effect cannot be rejected.

Relaxation of Viscoelastic Tumblers with Application to 1I/2017 (`Oumuamua) and 4179 Toutatis

description: Motivated by the observation of comets and asteroids rotating in non-principal axis (NPA) states, we investigate the relaxation of a freely precessing triaxial ellipsoidal rotator towards its lowest-energy spin state. Relaxation of the precession arises from internal dissipative stresses generated by self-gravitation and inertial forces from spin. We develop a general theory to determine the viscoelastic stresses in the rotator, under any linear rheology, for both long-axis (LAM) and short-axis (SAM) modes. By the methods of continuum mechanics, we calculate the power dissipated by the stress field and the viscoelastic material strain which enables us to determine the timescale of the precession dampening. To illustrate how the theory is used, we apply our framework to a triaxial 1I/2017 (`Oumuamua) and 4179 Toutatis under the Maxwell regime. For the former, employing viscoelastic parameters typical of very cold monolithic asteroids renders a dampening timescale longer by a factor of $10^{10}$ and higher than the timescales found in the works relying on the $\,Q$-factor approach, whilst the latter yields a significantly shorter timescale as a consequence of including self-gravitation. We further reduce our triaxial theory to bodies of an oblate geometry and derive a family of relatively simple analytic approximations determining the NPA dampening times for Maxwell rotators, as well as a criterion determining whether self-gravitation is negligible in the relaxation process. Our approximations exhibit a relative error no larger than $0.2\%$, when compared to numerical integration, for close to non-dissipative bodies and $0.002\%$ for highly energy dissipating rotators.

description: Wind, insects, or both? The pollination mode of chestnuts, an important genus of nut-producing forest trees of the Fagaceae family, is still unclear. We revisit this old question using an integrated approach, focusing on cultivated Castanea sativa trees and hybrids in South-western France. We first conducted a large-scale insect isolation experiment. We then monitored 16 trees, focusing on flowering phenology, flower abundance and insect visits. Half of these trees are male-sterile, helping explore the role of pollen in insect attraction. Finally, we characterized the pollination syndrome of chestnuts and contrasted it with that of wind-pollinated oaks using original and published data. Chestnut female flowers have erect styles resembling stamens from male flowers, a probable case of intersexual mimicry. The tree’s unusual phenology includes two peaks of pollen production. Pollinator exclusion experiments demonstrated a predominant role of insects in chestnut pollination. Flowering trees attract large numbers of beetles, bees and flies. In contrast, the few insects seen on female flowers (66 in 32 h of observation, <2% of the total) were mostly beetles. Compared to male-fertile trees, male-sterile trees attract fewer insects overall but their female flowers are more frequently visited and they have higher fruit set. All chestnut flower traits examined, such as the tiny pollen grains and the huge rate of pollen production, resulting in the highest pollen/ovule ratio ever reported in plants, are compatible with a beetle pollination syndrome. The high uncertainty of this pollination mode and its convergence with wind pollination explain the pervading confusion regarding chestnut pollination.

description: The Magnus expansion is an efficient alternative to solving similarity renormalization group (SRG) flow equations with high-order, memory-intensive ordinary differential equation solvers. The numerical simplifications it offers for operator evolution are particularly valuable for in-medium SRG calculations, though challenges remain for difficult problems involving intruder states. Here we test the Magnus approach in an analogous but more accessible situation, which is the free-space SRG treatment of the spurious bound-states arising from a leading-order chiral effective field theory (EFT) potential with very high cutoffs. We show that the Magnus expansion passes these tests and then use the investigations as a springboard to address various aspects of operator evolution that have renewed relevance in the context of the scale and scheme dependence of nuclear processes. These aspects include SRG operator flow with band- versus block-diagonal generators, universality for chiral EFT Hamiltonians and associated operators with different regularization schemes, and the impact of factorization arising from scale separation. Implications for short-range correlations physics and the possibilities for reconciling high- and low-resolution treatments of nuclear structure and reactions are discussed.

description: Where consumers have imperfect information about specific firms’ prices and lack information about the market, firms have informational market power. In general, improving the consumer’s information about each firm’s price will not necessarily lower average market price. We show, however, that certain types of improvements will lower price. Moreover, a reduction in barriers to entry (e.g., capital costs) will lower price-holding information constant. Where a significant number (but not all) consumers have perfect information, single-price equilibria are impossible.

description: In the description of the AdS5/CFT4 duality by an integrable system the scattering matrix for bound states plays a crucial role: it was initially constructed for the evaluation of finite size corrections to the planar spectrum of energy levels/anomalous dimensions by the thermodynamic Bethe ansatz, and more recently it re-appeared in the context of the glueing prescription of the hexagon approach to higher-point functions. In this work we present a simplified form of this scattering matrix and we make its pole structure manifest. We find some new relations between its matrix elements and also present an explicit form for its inverse. We finally discuss some of its properties including crossing symmetry. Our results will hopefully be useful for computing finite-size effects such as the ones given by the complicated sum-integrals arising from the glueing of hexagons, as well as help towards understanding universal features of the AdS5/CFT4 scattering matrix.

description: We show how to fix the renormalization scale for hard-scattering exclusive processes such as deeply virtual meson electroproduction by applying the BLM prescription to the imaginary part of the scattering amplitude and employing a fixed-t dispersion relation to obtain the scale-fixed real part. In this way we resolve the ambiguity in BLM renormalization scale-setting for complex scattering amplitudes. We illustrate this by computing the H generalized parton distribution at leading twist in an analytic quark-diquark model for the parton-proton scattering amplitude which can incorporate Regge exchange contributions characteristic of the deep inelastic structure functions.

A software framework for developing high quality control systems for autonomous robots
Creators: name: Lahey, Darrell M.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis presents a software framework and distributed execution system that allows developers to create control systems for autonomous robots. These control systems are behavior-based, and developers define them using networks of software components. The systems allow sequencing of behavior execution without coupling task sequencers with specific behaviors, and they allow groups of behaviors to be managed as single, cohesive, units. The presented software framework leverages the computational power of the Java programming language, while shielding developers from network communication details. In addition, it facilitates the development of high quality control systems, where quality refers to system usefulness and development ease. The presented software framework supports the functionality required to create control systems that allow robots to perform human-like tasks in environments inhabited by humans. Most importantly, it supports both deliberation and reactivity, along with task sequencing and the coordination of action requests. A navigation system for a simulated mobile robot, developed using this software framework, shows the usefulness of the framework and execution system. The framework does show weaknesses, however, in areas such as robustness, efficiency, and synchronization. Nonetheless, these weaknesses can be overcome, and the software framework and execution system, as a whole, show great potential.

description: This paper discusses properties of the European Large Area ISO Survey 15 micron quasars and tries to establish a robust method of quasar selection for future use within the Spitzer Wide-Area Infrared Extragalactic Survey (SWIRE) framework. The importance of good quality ground-based optical data is stressed, both for the candidates selection and for the photometric redshifts estimates. Colour-colour plots and template fitting are used for these purposes. The properties of the 15 micron quasars sample are studied, including variability and black hole masses and compared to the properties of other quasars that lie within the same fields but have no mid-infrared counterparts. The two subsamples do not present substantial differences and are believed to come from the same parent population.

description: We present a new measurement of CP-violation parameters in B0 -> Ks pi0 gamma decay based on a sample of 275 x 10^6 B\bar{B} pairs collected at the Upsilon(4S) resonance with the Belle detector at the KEKB energy-asymmetric e^+e^- collider. One of the B mesons is fully reconstructed in the B0 -> Ks pi0 gamma decay. The flavor of the accompanying B meson is identified from its decay products. CP-violation parameters are obtained from the asymmetry in the distribution of the proper-time intervals between the two B decays. We obtain S_Kspi0gamma = -0.58 +0.46-0.38(stat) +-0.11(syst) and A_Kspi0gamma = +0.03 +-0.34(stat) +-0.11(syst), for the Kspi0 invariant mass covering the full range up to 1.8 GeV/c^2. We also measure the CP-violation parameters for the case B0 -> K*0(-> Kspi0) gamma and obtain S_K*0gamma = -0.79 +0.63-0.50(stat) +- 0.10(syst) for A_K*0gamma fixed at 0.

description: A complete study of the angular distributions of the processes, $Λ_b \to Λ V(1^-)$, with $Λ\to p π^-$ and $V (J/Ψ) \to {\ell}^+ {\ell}^-$ or $V (ρ^0,ω) \to π^+ π^-,$ is performed. Emphasis is put on the initial $Λ_b$ polarization produced in the proton-proton collisions. The polarization density-matrices as well as angular distributions are derived and help to construct T-odd observables which allow us to perform tests of both Time-Reversal and CP violation.

description: JUNO is a multi-purpose neutrino experiment currently under construction in Jiangmen, China. It is primary aiming to determine the neutrino mass ordering. Moreover, its 20\,kt target mass makes it an ideal detector to study neutrinos from various sources, including nuclear reactors, the Earth and its atmosphere, the Sun, and even supernovae. Due to the small cross section of neutrino interactions, the event rate of neutrino experiments is limited. In order to maximize the signal-to-noise ratio, it is extremely important to control the background levels. In this paper we discuss the potential of particle identification in JUNO, its underlying principles and possible areas of application in the experiment. While the presented concepts can be transferred to any large liquid scintillator detector, our methods are evaluated specifically for JUNO and the results are mainly driven by its high optical photon yield of 1,200 photo electrons per MeV of deposited energy. In order to investigate the potential of event discrimination, several event pairings are analysed, i.e. $α/β$, $p/β$, $e^+/e^-$, and $e^-/γ$. We compare the discrimination performance of advanced analytical techniques based on neural networks and on the topological event reconstruction keeping the standard Gatti filter as a reference. We use the Monte Carlo samples generated in the physically motivated energy intervals. We study the dependence of our cuts on energy, radial position, PMT time resolution, and dark noise. The results show an excellent performance for $α/β$ and $p/β$ with the Gatti method and the neural network. Furthermore, $e^+/e^-$ and $e^-/γ$ can partly be distinguished by means of neural network and topological reconstruction on a statistical basis. Especially in the latter case, the topological method proved very successful.

description: Being able to duplicate published research results is an important process of conducting research whether to build upon these findings or to compare with them. This process is called "replicability" when using the original authors' artifacts (e.g., code), or "reproducibility" otherwise (e.g., re-implementing algorithms). Reproducibility and replicability of research results have gained a lot of interest recently with assessment studies being led in various fields, and they are often seen as a trigger for better result diffusion and transparency. In this work, we assess replicability in Computer Graphics, by evaluating whether the code is available and whether it works properly. As a proxy for this field we compiled, ran and analyzed 151 codes out of 374 papers from 2014, 2016 and 2018 SIGGRAPH conferences. This analysis shows a clear increase in the number of papers with available and operational research codes with a dependency on the subfields, and indicates a correlation between code replicability and citation count. We further provide an interactive tool to explore our results and evaluation data.

description: Colloidal particle submerged in a non-equilibrium fluid with a concentration gradient of solutes experiences diffusio-phoresis. Such directional transport originates from the driving forces that exert on the fluid in a microscopic boundary layer surrounding the colloid. Based on a simple model of spherical colloid fixed in a concentration gradient of solutes, molecular dynamics simulations are performed to determine the interaction parameters that maximise the diffusio-phoretic mobility, which cannot be properly measured by conventional continuum theory. The diffusio-phoretic mobility is found to depend non-monotonically on the strength of the interaction between the colloid and solutes, due to the presence of bound solutes within adsorption shell that cannot contribute to diffusio-phoresis. The results also show that the phoretic mobility depends sensitively on the density of solutes in bulk, due to the uneven distribution of excess particles surrounding the colloid at a microscopic level. The simulations suggest that diffusio-phoresis may in principle be applied to the selective transport, separation and purification for colloidal systems. By substituting the spherical colloid with other realistic macromolecules, the model could provide results that are quantitatively comparable with experiments.

description: Recently there has been considerable interest in the problem of finding a phylogenetic network with a minimum number of reticulation vertices which displays a given set of phylogenetic trees, that is, a network with minimum hybrid number. Even so, for certain evolutionary scenarios insisting that a network displays the set of trees can be an overly restrictive assumption. In this paper, we consider the less restrictive notion of displaying called weakly displaying and, in particular, a special case of this which we call rigidly displaying. We characterize when two trees can be rigidly displayed by a temporal tree-child network in terms of fork-picking sequences, a concept that is closely related to that of cherry-picking sequences. We also show that, in case it exists, the rigid hybrid number for two phylogenetic trees is given by a minimum weight fork-picking sequence for the trees, and that the rigid hybrid number can be quite different from the related beaded- and temporal-hybrid numbers.

description: Tiny basaltic samples containing finely grained titanomagnetite with Curie temperature less than 100 C were heated in air in weak field (25 to 100microT) at temperatures between 400 and 560 C for times as long as 32 hours. Oxyexsolution of titanomagnetite resulted in the crystallization of interacting single domain particles with Curie point close to 540 C and the concomitant development of one of two types chemical remanence, depending upon thermal treatment: isothermal chemical remanence (CRM) or thermochemical remanence (TCRM), the latter acquired under the combined effects of chemical change and temperature decrease. CRM and TCRM acquired under various conditions were subjected to Thellier-type experiments. The CRM/TRM ratio is found to be less than one and increases rapidly with acquisition temperature (0.35 at 400 C, 0.65 at 450 C, and 0.90 at 500 C). Thus, very large underestimate of geomagnetic field paleostrength can occur when a natural CRM is not recognized as such and is believed to be a natural TRM. In an attempt to mimic deuteric oxyexsolution in cooling magma, TCRM was imparted from 560 to 400 C at a cooling rate of 0.1 C/mn. The TCRM/TRM is found to slightly exceed one (1.10), in agreement with the theoretically predicted effect of the difference in cooling rate.
