The total synthesis of ±-[beta]-panasinsene
Creators: name: Story, Betty-Anne
Publisher: name: University of British Columbia
Year: 2009

description: This thesis describes a total synthesis of the sesquiterpenoid (±)-β-panasinsene (31). Two different routes for the synthesis of a bicyclic enone of general structure 74 were investigated. An unsuccessful attempt to generate a synthetically useful enone 74 employed the Pauson Khand cyclization of an enyne 75 (R= Me; XX= S(CH2)3S(CH or MeS, ρ-MeC6H4SO2). A second approach, which was based on the Weiss-Cook condensation of glyoxal (44) with dimethyl 3-oxoglutarate (45) led to the production of the dione 43, which was converted, via several steps, into the enone 159. The enone 1 59 was subjected to a methylenecyclohexane annulation sequence. Thus, copper (I)-catalyzed conjugate addition of the Grignard reagent 7 to 159, followed by intramolecular alkylation of the resultant chloro keto ester, provided the tricyclic intermediate 171. Sequential reduction of the keto function in 171, deoxygenation of the resultant hydroxyl function, and hydrolysis of the ketal moiety gave rise to the keto ester 182. Subjection of 182 to a photochemical Wolff ring contraction reaction sequence provided a mixture of the diesters 200 and 201. Alkylation of the mixture of 200 and 201 with methyl iodide, followed by a reduction-oxidation sequence, gave the dialdehyde 217. Wolff Kishner reduction of 21 7 resulted in the simultaneous deoxygenation of both of the carbonyl groups and successfully completed the synthesis of (±)-β-panasinsene (31).

description: The iterative and incremental nature of software development using models typically makes a model of a system incomplete (i.e., partial) until a more advanced and complete stage of development is reached. Existing model execution approaches (interpretation of models or code generation) do not support the execution of partial models. Supporting the execution of partial models at the early stages of software development allows early detection of defects, which can be fixed more easily and at a lower cost. This paper proposes a conceptual framework for the execution of partial models, which consists of three steps: static analysis, automatic refinement, and input-driven execution. First, a static analysis that respects the execution semantics of models is applied to detect problematic elements of models that cause problems for the execution. Second, using model transformation techniques, the models are refined automatically, mainly by adding decision points where missing information can be supplied. Third, refined models are executed, and when the execution reaches the decision points, it uses inputs obtained either interactively or by a script that captures how to deal with partial elements. We created an execution engine called PMExec for the execution of partial models of UML-RT (i.e., a modeling language for the development of soft real-time systems) that embodies our proposed framework. We evaluated PMExec based on several use-cases that show that the static analysis, refinement, and application of user input can be carried out with reasonable performance and that the overhead of approach, which is mostly due to the refinement and the increase in model complexity it causes, is manageable. We also discuss the properties of the refinement formally and show how the refinement preserves the original behaviors of the model.

description: Na2C60 is believed to be an electron-hole counterpart of the Mott-Jahn--Teller insulator A4C60 salts. We present a study of infrared, ESR, NMR spectroscopy, X-ray diffraction, chemical composition and neutron scattering on this compound. Our spectroscopic results at room temperature can be reconciled in a picture of segregated, separate regions of the size 3--10 nm. We observe a significant insulating C60 phase and at least two more phases, one of which we assign to metallic Na3C60. The separation disappears on heating by jump diffusion of the sodium ions, which we followed by neutron scattering. Above ~460 K we see infrared spectroscopic evidence of a Jahn--Teller distorted (C60)2- anion.

description: For a target task where labeled data is unavailable, domain adaptation can transfer a learner from a different source domain. Previous deep domain adaptation methods mainly learn a global domain shift, i.e., align the global source and target distributions without considering the relationships between two subdomains within the same category of different domains, leading to unsatisfying transfer learning performance without capturing the fine-grained information. Recently, more and more researchers pay attention to Subdomain Adaptation which focuses on accurately aligning the distributions of the relevant subdomains. However, most of them are adversarial methods which contain several loss functions and converge slowly. Based on this, we present Deep Subdomain Adaptation Network (DSAN) which learns a transfer network by aligning the relevant subdomain distributions of domain-specific layer activations across different domains based on a local maximum mean discrepancy (LMMD). Our DSAN is very simple but effective which does not need adversarial training and converges fast. The adaptation can be achieved easily with most feed-forward network models by extending them with LMMD loss, which can be trained efficiently via back-propagation. Experiments demonstrate that DSAN can achieve remarkable results on both object recognition tasks and digit classification tasks.

AfD identity priming and well-being /vaccination opponents, identity priming and well-being
Creators: name: Adena, Maja
Publisher: name: OSF Registries
Year: 2023
Subjects: subject: Social and Behavioral Sciences

description: This project contains two subprojects
1) We set to explore a potential direction of causality from becoming an AfD supporter towards reduced well-being. This challenges the usual approach to assuming that well-being is rather a determinant of party partisanship. We test this by the means of party identity priming. In our formal analysis we focus on voters who have expressed some sympathy with the AfD program but who may not yet have established a fully formed identity as firm AfD supporters, that is, a group of voters that may arguably be susceptible to priming. We also expect the effect to be stronger in the West of Germany where AfD is a minority party as opposed to the East.
2) We set to explore how belonging to a minority group might affect well-being. We concentrate on the current context of COVID-19 vaccination and those opposing to it. At the time of planning the study almost 80% of the adult population in Germany is vaccinated and the remainder seems to be weakly or strongly opposed to vaccination. We will apply a method of identity priming (vaccination opponent) by asking for the motivation for not getting the shot, see enclosed questionnaire. We will also test interaction effects to party identity priming.

It's a Wrap! Visualisations that Wrap Around Cylindrical, Toroidal, or Spherical Topologies
Creators: name: Chen, Kun-Ting
Publisher: name: arXiv
Year: 2022
Subjects: subject: Human-Computer Interaction (cs.HC)
subject: FOS: Computer and information sciences

description: Traditional visualisations are designed to be shown on a flat surface (screen or page) but most data is not "flat". For example, the surface of the earth exists on a sphere, however, when that surface is presented on a flat map, key information is hidden, such as geographic paths on the spherical surface being wrapped across the boundaries of the flat map. Similarly, cyclical time-series data has no beginning or end. When such cyclical data is presented on a traditional linear chart, the viewer needs to perceive continuity of the visualisation across the chart's boundaries. Mentally reconnecting the chart across such a boundary may induce additional cognitive load. More complex data such as a network diagram with hundreds or thousands of links between data points leads to a densely connected structure that is even less "flat" and needs to wrap around in multiple dimensions. To improve the usability of these visualisations, this thesis explores a novel class of interactive wrapped data visualisations, i.e., visualisations that wrap around continuously when interactively panned on a two-dimensional projection of surfaces of 3D shapes, specifically, cylinder, torus, or sphere. We start with a systematic exploration of the design space of interactive wrapped visualisations, characterising the visualisations that help people understand the relationship within the data. Subsequently, we investigate a series of wrappable visualisations for cyclical time series, network, and geographic data. We show that these interactive visualisations better preserve the spatial relations in the case of geospatial data, and better reveal the data's underlying structure in the case of abstract data such as networks and cyclical time series. Furthermore, to assist future research and development, we contribute layout algorithms and toolkits to help create pannable wrapped visualisations.
XMM-Newton observation of the Be/neutron star system RX J0146.9+6121: a soft X-ray excess in a low luminosity accreting pulsar

description: We report on the XMM-Newton observation of the Be/neutron star X-ray binary system RX J0146.9+6121, a long period (~ 23 m) pulsar in the NGC 663 open cluster. The X-ray luminosity decreased by a factor two compared to the last observation carried out in 1998, reaching a level of ~ 10^34 erg/s, the lowest ever observed in this source. The spectral analysis reveals the presence of a significant excess at low energies over the main power-law spectral component. The soft excess can be described by a black-body spectrum with a temperature of about 1 keV and an emitting region with a radius of ~ 140 m. Although the current data do not permit to ascertain whether the soft excess is pulsed or not, its properties are consistent with emission from the neutron star polar cap. This is the third detection of a soft excess in a low luminosity (~ 10^34 erg/s) pulsar, the other being X Per and 3A 0535+262, suggesting that such spectral component, observed up to date in higher luminosity systems, is a rather common feature of accreting X-ray pulsars. The results on these three sources indicate that, in low luminosity systems, the soft excess tends to have a higher temperature and a smaller surface area than in the high luminosity ones.

description: Conventional methods to calculate the thermodynamics of crystals evaluate the harmonic phonon spectra and therefore do not work in frequent and important situations where the crystal structure is unstable in the harmonic approximation, such as the body-centered cubic (bcc) crystal structure when it appears as a high-temperature phase of many metals. A method for calculating temperature dependent phonon spectra self consistently from first principles has been developed to address this issue. The method combines concepts from Born's inter-atomic self-consistent phonon approach with first principles calculations of accurate inter-atomic forces in a super-cell. The method has been tested on the high temperature bcc phase of Ti, Zr and Hf, as representative examples, and is found to reproduce the observed high temperature phonon frequencies with good accuracy.

description: The mass of unresolved young star clusters derived from spectro-photometric data may well be off by a factor of 2 or more once the migration of massive stars driven by mass segregation is accounted for. We quantify this effect for a large set of cluster parameters, including variations in the stellar IMF, the intrinsic cluster mass, and mean mass density. Gas-dynamical models coupled with the Cambridge stellar evolution tracks allow us to derive a scheme to recover the real cluster mass given measured half-light radius, one-dimensional velocity dispersion and age. We monitor the evolution with time of the ratio of real to apparent mass through the parameter eta. When we compute eta for rich star clusters, we find non-monotonic evolution in time when the IMF stretches beyond a critical cutoff mass of 25.5 solar mass. We also monitor the rise of color gradients between the inner and outer volume of clusters: we find trends in time of the stellar IMF power indices overlapping well with those derived for the LMC cluster NGC 1818 at an age of 30 Myr. We argue that the core region of massive Antennae clusters should have suffered from much segregation despite their low ages. We apply these results to a cluster mass function, and find that the peak of the mass distribution would appear to observers shifted to lower masses by as much as 0.2 dex. The star formation rate (SFR) derived for the cluster population is then underestimated by from 20 to 50 per cent.

Self-gravitating Equilibria of Non-minimally Coupled Dark Matter Halos

description: We investigate self-gravitating equilibria of halos constituted by dark matter (DM) non-minimally coupled to gravity. In particular, we consider a theoretically motivated non-minimal coupling which may arise when the averaging/coherence length $L$ associated to the fluid description of the DM collective behavior is comparable to the local curvature scale. In the Newtonian limit, such a non-minimal coupling amounts to a modification of the Poisson equation by a term $L^2\,\nabla^2ρ$ proportional to the Laplacian of the DM density $ρ$ itself. We further adopt a general power-law equation of state $p\propto ρ^Γ\, r^α$ relating the DM dynamical pressure $p$ to density $ρ$ and radius $r$, as expected by phase-space density stratification during the gravitational assembly of halos in a cosmological context. We confirm previous findings that, in absence of the non-minimal coupling, the resulting density $ρ(r)$ features a steep central cusp and an overall shape mirroring the outcomes of $N-$body simulations in the standard $Λ$CDM cosmology, as described by the classic NFW or Einasto profiles. Most importantly, we find that the non-minimal coupling causes the density distribution to develop an inner core and a shape closely following, out to several core scale radii, the Burkert profile. In fact, we highlight that the resulting mass distributions can fit, with an accuracy comparable to the Burkert's one, the co-added rotation curves of dwarf, DM-dominated galaxies. Finally, we show that non-minimally coupled DM halos are consistent with the observed scaling relation between the core radius $r_0$ and core density $ρ_0$, in terms of an universal core surface density $ρ_0\times r_0$ among different galaxies.

description: The increased need in pointing performance for Earth observation and science Space missions together with the use of lighter and flexible structures directly come with the need of a robust pointing performance budget from the very beginning of the mission design. An extensive understanding of the system physics and its uncertainties is then necessary in order to push control design to the limits of performance and constrains the choice of the set of sensors and actuators. A multi-body framework, the TITOP approach, is used to build all the elementary flexible bodies and mechanisms involved in a fine pointing mission. This framework allows the authors to easily include all system dynamics with an analytical dependency on varying and uncertain mechanical parameters in a unique Linear Fractional Transformation model. This approach opens the doors to modern robust control techniques that robustly guarantee the expected fine pointing requirements. A novel control architecture is proposed to reduce the microvibrations induced both by reaction wheel imbalances and Solar Array Drive Mechanism driving signal, by letting them work during the imaging phase. Thanks to a set of accelerometers placed at the isolated base of the payload and in correspondence of the mirrors with the largest size in a Space telescope (typically the primary and secondary ones), it is possible to estimate the line-of-sight error at the payload level by hybridizing them with the low-frequency measurements of the camera. While a classical Fast Steering Mirror in front of the camera can compensate for a large amount of microvibration, an innovative architecture with a set of six Proof-Mass Actuators installed at the payload isolator level can further improve the pointing performance.

description: We study the ultraviolet behaviour of Higgs inflation models above the apparent unitarity violation scale arising from the large non minimal coupling to gravity, by computing on-shell 4-point scattering amplitudes in the presence of a large inflaton background, away from the electroweak vacuum. We find that all tree-level amplitudes are well behaved at high energies below the inflaton background that can thus take values up to the Planck scale. This result holds in both the metric and Palatini formulation, and is independent of the frame (Jordan or Einstein) as expected. The same result also holds if an $R^2$ term is added to the action.

Heterocumulene insertions with group 6 Diaryl Nitrosyl complexes
Creators: name: Brouwer, Eric B.
Publisher: name: University of British Columbia
Year: 2008

description: Treatment of the 16-electron complexes Cp*M(NO)(aryl)2 (Cp* = i5-05Me5; M =Mo, W; aryl = phenyl, o-tolyl, p-tolyl) with the heterocumulenes carbon dioxide, p-tolylisocyanate, and carbon disulfide leads to the i2-carboxylate-, i2-amide-, and i2-thiocarboxylate-containing complexes, respectively, in 10-50% yields. Treatment with a fourth member of the heterocumulene class, diphenylketene, does not result in an isolable inserted complex, although spectroscopic data suggest that insertion has taken place. Cp*M(NO)(aryl)2 complexes thus insert one heterocumulene molecule into a metal-aryl bond; the other metal-aryl bond is inert to further insertion. The resulting complexes are thermally stable and air-stable, and can be described as being 18-electron species. Protonolysis of the representative heterocumulene-inserted complex Cp*W(NO){112-N(p-tol)C(0)Ph}Ph releases the functionalized heterocumulene molecule, p-tolylbenzamide.All new complexes have been fully characterized by conventional methods. In addition, Cp*W(NO)(r12-S2CPh)Ph reacts with the Lewis base trimethylphosphine to form Cp*W(NO){112-S2C(PMe3)Ph}Ph which contains a zwitterionic phosphonium-betaine ligand. X-ray crystallographic studies of Cp*W(NO){1.12-82C(PMe3)Ph}Ph and Cp*W(N0)(112-0NPh)(NPh)Ph are reported and discussed.

description: We discuss the possibility of realizing metal-insulator transitions with ultracold atoms in two-dimensional optical lattices in the presence of artificial gauge potentials. Such transitions have been extensively studied for magnetic fields corresponding to Abelian gauges; they occur when the magnetic flux penetrating the lattice plaquette is an irrational multiple of the magnetic flux quantum. Here we present the first study of these transitions for non-Abelian U(2) gauge fields, which can be realized with atoms with two pairs of degenerate internal states. In contrast to the Abelian case, the spectrum and localization transition in the non-Abelian case is strongly influenced by atomic momenta. In addition to determining the localization boundary, the momentum fragments the spectrum and the minimum energy viewed as a function of momentum exhibits a step structure. Other key characteristics of the non-Abelian case include the absence of localization for certain states and satellite fringes around the Bragg peaks in the momentum distribution and an interesting possibility that the transition can be tuned by the atomic momenta.

description: Density of states (DOS) and absorption spectrum of weakly doped, narrow quantum wells in high magnetic fields are calculated by realistic exact diagonalization. The systems containing an electron--hole pair with and without an additional, second electron are compared. In DOS, the exciton--electron interaction is shown to fill the gaps between Landau levels and to yield additional discrete peaks corresponding to bound trion states. In absorption, interaction with the additional free electron causes no shift or renormalization of main, excitonic peaks. However, it results in additional, weaker peaks associated with bound trions in the lowest or higher Landau levels. The calculation is supplemented with experimental photoluminescence and photoluminescence-excitation studies of two-dimensional holes and electrons in high magnetic fields.

description: Quantum theory is the foundation of modern physics. Some of its basic principles, such as Born's rule, however, are based on postulates which require experimental testing. Any deviation from Born's rule would result in higher-order interference and can thus be tested in an experiment. Here, we report on such a test with a quantum light source based on a color center in hexagonal boron nitride (hBN) coupled to a microcavity. Our room temperature photon source features a narrow linewidth, high efficiency, high purity, and on-demand single-photon generation. With the single-photon source we can increase the interferometric sensitivity of our three-path interferometer compared to conventional laser-based light sources by fully suppressing the detector nonlinearity. We thereby obtain a tight bound on the third-order interference term of $3.96(523)\times 10^{-4}$. We also measure an interference visibility of 98.58% for our single-photons emitted from hBN at room temperature, which provides a promising route for using the hBN platform as light source for phase-encoding schemes in quantum key distribution.
Metalloporphyrin catalyzed oxidation of chlorophenols
Creators: name: Sveinson, Kelly P.
Publisher: name: University of British Columbia
Year: 2008

description: The use of water soluble, non-aggregating metalloporphyrins (meso-tetra(2,6-dichloro-3-sulphonatophenyl) porphyrin (TDCSPP) and meso-tetra(2,6-dichloro-3-sulfonatopheny1)-β-octachloroporphyrin (TDCS-(β-Cl₈P) coordinated with iron or manganese) as catalysts for the peroxide oxidation of chlorophenols were investigated. The relative rates of chlorophenol oxidation with respect to several variables (catalyst, pH, oxidant, and chlorophenol structure) were determined. The rate was found to be pseudo-first order in the catalyst. The oxidation was most efficient using the iron porphyrins, at pH < 4. The oxidation rate was dependent on the oxidant. In order of decreasing rate, meta-chloroperoxybenzoic acid > potassium monoperoxysulfate > hydrogen peroxide > t-butylhydroperoxide. The oxidation rate was strongly dependent on both the number and the position of chlorine substitution on the phenol. In order of decreasing rate, 2,4-dichlorophenol > 2,4,5-trichlorophenol > 2-chlorophenol ≈ 4-chlorophenol > 3,4-dichlorophenol ≈ 2,4,6-trichlorophenol > 2,3,4,6-tetrachlorophenol 2,3,5,6-tetrachlorophenol > 3-chlorophenol > 3,5-dichlorophenol ≈ 2,3,4,5-tetrachlorophenol. The structures of some of the catalyzed reactions were elucidated. Products of phenoxy radical coupling, and quinones are typical. The results are discussed in the context of the possible use of these metalloporphyrins for pollution remediation.

Spontaneous CP Violation in SUSY SO(10)

description: A scenario is suggested for spontaneous CP violation in non-SUSY and SUSY- SO(10). The idea is to have a scalar potential which generates spontaneously a phase, at the high scale, in the VEV that gives a mass to the RH neutrinos. As a possible realization the case of the minimal renormalizable SUSY SO(10) is discussed in detail and one finds that a phase is induced in the CKM matrix. It is also pointed out that, in these models, the scales of Baryogenesis, Seesaw, Spontaneous CP violation and Spontaneous U(1)PQ breaking are all at the same order of magnitude.

description: Purpose: Random item generation (RIG) involves central executive functioning. Measuring aspects of random sequences can therefore provide a simple method to complement other tools for cognitive assessment. We examine the extent to which RIG relates to specific measures of cognitive function, and whether those measures can be estimated using RIG only. Method: Twelve healthy older adults (age: M = 70.3 years, SD = 4.9; 8 women and 4 men) and 20 healthy young adults (age: M = 24 years, SD = 4.0; 12 women and 8 men) participated in this pilot study. Each completed a RIG task, along with the color Stroop test, the Repeatable Battery for the Assessment of Neuropsychological Status, and the Peabody Picture Vocabulary Test–Fourth Edition (Dunn & Dunn, 2007). Several statistical features extracted from RIG sequences, including recurrence quantification, were found to be related to the other measures through correlation, regression, and a neural-network model. Results: The authors found significant effects of age in RIG and demonstrate that nonlinear machine learning can use measures of RIG to accurately predict outcomes from other tools. Conclusions: These results suggest that RIG can be used as a relatively simple predictor for other tools and in particular seems promising as a potential screening tool for selective attention in healthy aging.
The Serret-Andoyer Formalism in Rigid-Body Dynamics: I. Symmetries and Perturbations

description: This paper reviews the Serret-Andoyer (SA) canonical formalism in rigid-body dynamics and presents some new results. As is well known, the problem of unsupported and unperturbed rigid rotator can be reduced. The availability of this reduction is offered by the underlying symmetry, which stems from conservation of the angular momentum and rotational kinetic energy. When a perturbation is turned on, these quantities are no longer preserved. Nonetheless, the language of reduced description remains extremely instrumental even in the perturbed case. We describe the canonical reduction performed by the Serret-Andoyer (SA) method, and discuss its applications to attitude dynamics and to the theory of planetary rotation. Specifically, we consider the case of angular-velocity-dependent torques, and discuss the variation-of-parameters-inherent antinomy between canonicity and osculation. Finally, we address the transformation of the Andoyer variables into the action-angle ones, using the method of Sadov.

description: The dependence of the Curie temperature Tc on nearly hydrostatic pressure has been determined to 17.2 GPa for the weak itinerant ferromagnetic SrRuO3 in both polycrystalline and single-crystalline form. Tc is found to decrease under pressure from 162 K to 42.7 K at 17.2 GPa in nearly linear fashion at the rate dTc/dP = -6.8 K/GPa. No superconductivity was found above 4 K in the pressure range 17 to 34 GPa. Room-temperature X-ray diffraction studies to 25.3 GPa reveal no structural phase transition but indicate that the average Ru-O-Ru bond angle passes through a minimum near 15 GPa. The bulk modulus and its pressure derivative were determined to be B =192(3) GPa and B' = 5.0(3), respectively. Parallel ac susceptibility studies on polycrystalline CaRuO3 at 6 and 8 GPa pressure found no evidence for either ferromagnetism or superconductivity above 4 K.

description: We argue for a cost-effective, long-term North American underground science strategy based on partnership with Canada and initial construction of a modest U.S. Stage I laboratory designed to complement SNOLab. We show, by reviewing the requirements of detectors now in the R&D phase, that SNOLab and a properly designed U.S. Stage I facility would be capable of meeting the needs of North America's next wave of underground experiments. We discuss one opportunity for creating a Stage I laboratory, the Pioneer tunnel in Washington State, a site that could be developed to provide dedicated, clean, horizontal access. This unused tunnel, part of the deepest (1040 m) tunnel system in the U.S., would allow the U.S. to establish, at low risk and low cost, a laboratory at a depth (2.12 km.w.e., or kilometers of water equivalent) quite similar to that of the Japanese laboratory Kamioka (2.04 km.w.e.). We describe studies of cosmic ray attenuation important to properly locating such a laboratory, and the tunnel improvements that would be required to produce an optimal Stage I facility. We also discuss possibilities for far-future Stage II (3.62 km.w.e.) and Stage III (5.00 km.w.e.) developments at the Pioneer tunnel, should future North American needs for deep space exceed that available at SNOLab.

Magnetothermopower in Nd1-xEuxNiO3 compounds

description: We have measured magnetization M(T,H), electrical resistivity ro(T,H), thermal conductivity k(T,H), and thermopower S(T,H) of polycrystalline samples of Nd1-xEuxNiO3; 0 <= x <= 0.35; as a function of temperature and external magnetic field. The data indicate a metal-insulator transition (MI) in a wide range of temperature (200 < TMI < 325 K). The magnetic susceptibility X(T) data, after the subtraction of the rare-earth contribution, exhibit a Curie-Weiss like behavior at temperatures above TMI. Although a clear antiferromagnetic AF transition of the Ni sub-lattice is observed at TN <= TMI, X(T) still increases down to 5 K, suggesting a heterogeneous ground state. The thermal conductivity of the NdNiO3 compound is not affected by an external magnetic field of 90 kOe in a wide range of temperature, and its temperature dependence below 15 K is approximately quadratic, strongly suggesting the presence of disorder. S(T) is negative above TMI and varies linearly with temperature. Below TMI, S(T) does not follow the expected behavior of insulating compounds. There is a minimum close to 120 K, and S(T) changes its sign at T ~ 30 K, indicating a competition between two types of charge carriers. A pronounced peak in S(T) at TS ~ 20 K does not follow the expected phonon-drag temperature dependence either above or below TS and the peak remains unaltered under magnetic fields up to 90 kOe. However, its magnitude is enhanced by ~ 25 % with applied magnetic field, exhibiting a clear magnetothermopower effect. The combined results indicate a coexistence of ordered and disordered phases below TN and that an applied magnetic field is suitable for enhancing the thermoelectric properties close to TS.

description: Stochastic hybrid systems involve a coupling between a discrete Markov chain and a continuous stochastic process. If the latter evolves deterministically between jumps in the discrete state, then the system reduces to a piecewise deterministic Markov process (PDMP). Well known examples include stochastic gene expression, voltage fluctuations in neurons, and motor-driven intracellular transport. In this paper we use coherent spin states to construct a new path integral representation of the probability density functional for stochastic hybrid systems, which holds outside the weak noise regime. We use the path integral to derive a system of Langevin equations in the semi-classical limit, which extends previous diffusion approximations based on a quasi-steady-state reduction. We then show how in the weak noise limit the path integral is equivalent to an alternative representation that was previously derived using Doi-Peliti operators. The action functional of the latter is related to a large deviation principle for stochastic hybrid systems.

description: We have investigated the structure of cyclohexene-2-ethanamine molecule both theoretically and experimantally. Theoretical investigation is based on a first principle technique Density Functional Theory (DFT) using plane wave basis sets and ultrasoft pseudo-potentials while the experimental technique is infrared (IR) spectroscopy. Exchange-correlation potential of DFT was approximated in the frame of both local density approximation (LDA) and generalized gradient approximation (GGA) schemes. Vibrational properties of this molecule are given by the assignments in the range for wavenumber 4000-400 $cm^{-1}$. Stable equilibrium structure of the molecule was also obtained by using LDA and GGA. Obtained optimized geometrical structure was used to calculate vibrational properties and STM images. A remarkable agreement was obtained between theory and experiment, especially in the symmetric and asymmetric vibrations of NH groups.
