title: The Riga Mission: The Reports of the First American Outpost on the Soviet Border, 1924-1933
Creators: name: Acosta, Jeffrey
Publisher: name: Old Dominion University Libraries
Year: 1992

description: From 1917 to 1933, the United States did not recognize the Union of Soviet Socialist Republics. In 1920 the United States established conditions for recognition. First, the Soviet Union had to pay all debts owed to the United States government and its citizens by previous Russian and Soviet governments. In addition, all propaganda and subversive activities sponsored by the Soviet Union in the United States had to cease. During this period, the Division of Eastern European Affairs (DEEA) studied and collected data about the Soviet Union from its main "outpost" at the United States Mission in Riga, Latvia. The Russian specialists of the DEEA in Riga and Washington used the data collected to write scholarly reports about the Soviet Union and the Communist International. This thesis will analyze the reports written by the Russian specialists at the Riga mission and illustrate that the reports successfully defended the policy of nonrecognition by accurately demonstrating the Soviet Union's support of subversive propaganda activities in the United States.
X-ray natural dichroism and chiral order in underdoped cuprates

description: The origin of the Kerr rotation observed in the pseudogap phase of cuprates has been the subject of much speculation. Recently, it has been proposed that this rotation might be due to chiral charge order. Here, I investigate whether such order can be observed by x-ray natural circular dichroism (XNCD). Several types of charge order were considered, and they can give rise to an XNCD signal depending on the stacking of the order along the c-axis.

description: We study diffusive electron-electron interaction correction to conductivity by analyzing simultaneously $ρ_{xx}$ and $ρ_{xy}$ for disordered 2D electron systems in Si in tilted magnetic field. Tilting the field is shown to be a straightforward tool to disentangle spin and orbital effects. In particular, by changing the tilt angle we prove experimentally that in the field range $gμ_BB>k_BT$ the correction depends on modulus of magnetic field rather than on its direction, which is expected for a system with isotropic $g$-factor. In the high-field limit the correction behaves as $\ln (B)$, as expected theoretically (Lee, Ramakrishnan, Phys. Rev. B{\bf 26}, 4009 (1982)). Our data prove that the diffusive electron-electron interaction correction to conductivity is not solely responsible for the huge and temperature dependent magnetoresistance in parallel field, typically observed in Si-MOSFETs.

description: We present a theoretical and experimental analysis of the joint effects of the transverse electric field distribution and of the nonlinear crystal characteristics on the properties of photon pairs generated by spontaneous parametric downconversion (SPDC). While it is known that for a sufficiently short crystal the pump electric field distribution fully determines the joint signal-idler properties, for longer crystals the nonlinear crystal properties also play an important role. In this paper we present experimental measurements of the angular spectrum (AS) and of the conditional angular spectrum (CAS) of photon pairs produced by spontaneous parametric downconversion (SPDC), carried out through spatially-resolved photon counting. In our experiment we control whether or not the source operates in the short-crystal regime through the degree of pump focusing, and explicitly show how the AS and CAS measurements differ in these two regimes. Our theory provides an understanding of the boundary between these two regimes and also predicts the corresponding differing behaviors.

description: We enumerate the simplest models that have baryon number violation at the classical level but do not give rise to proton decay. These models have scalar fields in two representations of SU(3) x SU(2) x U(1) and violate baryon number by two units. Some of the models give rise to neutron-antineutron oscillations, while some also violate lepton number by two units. We discuss the range of scalar masses for which neutron-antineutron oscillations are measurable in the next generation of experiments. We give a brief overview of the phenomenology of these models and then focus on one of them for a more quantitative discussion of neutron-antineutron oscillations, the generation of the cosmological baryon number, the electric dipole moment of the neutron, and neutral kaon mixing.

description: We report an essential improvement of the plain Fourier Monte Carlo algorithm that promises to be a powerful tool for investigating critical behavior in a large class of lattice models, in particular those containing microscopic or effective long-ranged interactions. On tuning the Monte Carlo acceptance rates separately for each wave vector, we are able to drastically reduce critical slowing down. We illustrate the resulting efficiency and unprecedented accuracy of our algorithm with a calculation of the universal elastic properties of crystalline membranes in the flat phase and derive a numerical estimate eta = 0.795(10) for the critical exponent eta that challenges those derived from other recent simulations. The large system sizes accessible to our present algorithm also allow to demonstrate that insufficiently taking into account corrections to scaling may severely hamper a finite size scaling analysis. This observation may also help to clarify the apparent disagreement of published numerical estimates of eta in the existing literature.

description: Recent observations of considerable spin polarization in photoemission from metal surfaces through monolayers of chiral molecules were followed by several efforts to rationalize the results as the effect of spin-orbit interaction that accompanies electronic motion on helical, or more generally strongly curved, potential surfaces. In this paper we (a) argue, using simple models, that motion in curved force-fields with the typical energies used and the characteristic geometry of DNA cannot account for such observations; (b) introduce the concept of induced spin filtering, whereupon selectivity in the transmission of the electron orbital angular momentum can induce spin selectivity in the transmission process provided there is strong spin-orbit coupling in the substrate; and (c) show that the spin polarizability in the tunneling current as well as the photoemission current from gold covered by helical adsorbates can be of the observed order of magnitude. Our results can account for most of the published observations that involved gold and silver substrates, however recent results obtained with an aluminum substrate can be rationalized within the present model only if strong spin-orbit coupling is caused by the built-in electric field at the molecule-metal interface.

description: Coral reefs occupy only similar to 0.1 percent of the ocean's habitat, but are the most biologically diverse marine ecosystem. In recent decades, coral reefs have experienced a significant global decline due to a variety of causes, one of the major causes being widespread coral bleaching events. During bleaching, the coral expels its symbiotic algae, thereby losing its main source of nutrition generally obtained through photosynthesis. While recent coral bleaching events have been extensively investigated, there is no scientific data on historical coral bleaching prior to 1979. In this study, we employ high-resolution femtosecond Laser Ablation Multiple Collector Inductively Coupled Plasma Mass Spectrometry (LA-MC-ICP-MS) to demonstrate a distinct biologically induced decline of boron (B) isotopic composition (delta B-11) as a result of coral bleaching. These findings and methodology offer a new use for a previously developed isotopic proxy to reconstruct paleo-coral bleaching events. Based on a literature review of published delta B-11 data and our recorded vital effect of coral bleaching on the delta B-11 signal, we also describe at least two possible coral bleaching events since the Last Glacial Maximum. The implementation of this bleaching proxy holds the potential of identifying occurrences of coral bleaching throughout the geological record. A deeper temporal view of coral bleaching will enable scientists to determine if it occurred in the past during times of environmental change and what outcome it may have had on coral population structure. Understanding the frequency of bleaching events is also critical for determining the relationship between natural and anthropogenic causes of these events.

description: We present new results on Boolean matrix factorization and a new algorithm based on these results. The results emphasize the significance of factorizations that provide from-below approximations of the input matrix. While the previously proposed algorithms do not consider the possibly different significance of different matrix entries, our results help measure such significance and suggest where to focus when computing factors. An experimental evaluation of the new algorithm on both synthetic and real data demonstrates its good performance in terms of good coverage by the first k factors as well as a small number of factors needed for exact decomposition and indicates that the algorithm outperforms the available ones in these terms. We also propose future research topics.

description: We present a new method based on the scattering technique to investigate fluctuation-induced forces at a fluid interface. The scattering approach, well suited to the study of many body systems of arbitrary geometries, is augmented to include boundary fluctuations. Using this method, we study the deviation of the total fluctuation-induced interaction from the sum of pairwise energies for three colloidal particles. We consider both frozen and fluctuating colloids and obtain a very good agreement between analytical and numerical results. We find a marked difference in the three body fluctuation-induced free energy between the frozen and fluctuating colloids, both in sign and relative size.

description: We demonstrate that the isotope shift in isotopomers of diatomic molecules, where the nucleus of one of its constituent atoms is replaced by another isotope, can be expressed as the sum of a field shift and a mass shift, similar to the atomic case. We show that a linear relation holds between atomic and molecular isotopes shifts, thus extending the King-plot analysis to molecular isotope shifts. Optical isotope shifts in YbF and ZrO and infrared isotope shifts in SnH are analyzed with a molecular King-plot approach, utilizing Yb$^{+}$ and Zr$^{+}$ ionic isotope shifts and charge radii of Sn obtained with non-optical methods. The changes in the mean-squared nuclear charge radii $δ\langle r^2 \rangle$ of $^{170-174,176}$Yb and $^{90-92,94,96}$Zr extracted from the molecular transitions are found to be in excellent agreement with the values from the spectroscopy of Yb$^{+}$ and Zr$^{+}$, respectively. On the contrary, in the case of the vibrational-rotational transition in SnH, no sensitivity to the nuclear volume could be deduced within the experimental resolution, which makes it unsuitable for the extraction of nuclear charge radii but provides insights into the molecular electronic wave function not accessible via other methods. The new opportunities offered by the molecular King-plot analysis for research in nuclear structure and molecular physics are discussed.

description: Being a pathway tightly linked to photosynthesis, photorespiration is regulated by light, but also by both nutrients and metabolites on transcriptional level. However, only little is known about the signals and how they are integrated on promoter level to coordinate the whole pathway. Using a bioinformatic approach we analyzed the co-expression patterns of photorespiratory genes, the predicted cis-regulatory elements in their 5′ upstream regions and the existence of introns in their 5′UTRs. We found that there are groups of photorespiratory genes that are strongly co-expressed among each other. The analysis showed a high co-expression between photorespiration and ammonia re-fixation. However, a strong co-regulation between two genes, like GDCH1 and GDCH2, did not necessarily mean that these genes share common cis-element in their 5′ upstream regions. TATA-box, MYB1AT, and MYB4 binding site motifs occurred in 16 out of 20 genes. Furthermore, photorespiratory genes are subjected to alternative splicing. We discuss the presence of cis-elements in the context of both stress responses and development. A genome wide analysis of Arabidopsis 5′UTRs revealed that 5′UTRs introns are overrepresented in photorespiratory genes. Promoter:gusA studies indicated that photorespiratory gene expression is also regulated by intron-mediated enhancement (IME). As already shown for glutamate: glyoxylate aminotransferase, transcript abundance of serine: glyoxylate aminotransferase was affected by IME on mRNA level. IME of gene expression of glycolate oxidase was shown to act on translational level.

description: The influence of porous media wettability on the mobility of colloids is mostly unknown. In the present work, organic-matter-coated goethite (OMCG) colloids were percolated through three saturated soil materials differing in wettability: untreated quartz sand and two variants of hydrophobized sand. For each type of sand, three ionic strength levels were applied. Derjaguin–Landau–Verwey– Overbeek (DLVO) and Lewis acid–base extended DLVO (XDLVO) interaction energy profiles were calculated according to contact angles and zeta potentials. Flow column results elucidated that decreasing sand wettability had no relevant effect on OMCG colloid mobility. In contrast, colloid retention increased with ionic strength in each type of sand packing. Classic DLVO interactions could predict trends in colloid retention by the respective characteristics of energy barriers and secondary minima. The extension with Lewis acid–base interactions in the XDLVO approach led to the prediction of significant short-range (∼2 nm) attractive interaction energies between colloids and hydrophobized sand, which were not reflected by colloid breakthrough behavior. This was probably due to substantial energy barriers calculated for larger distances (∼27 to ∼75 nm, depending on ionic strength) between the solid matrix and colloids. It is concluded that the distinct surface roughness of sand grains and colloids probably weakened the strength of the short-range attractive interactions, because larger amounts of surface area were still outside the effective distance for the short-range interactions predicted by XDLVO. Regarding colloidal mobility, we concluded for our saturated porous systems that near-surface attractive XDLVO interaction energies between OMCG colloids and hyrophobized sand did not significantly affect colloid mobility.

To this similarity with single-molecule magnets they own their name. In this chapter the distinctive features of single-chain magnets as opposed to their precursors will be pinpointed. In particular, we will show how their behaviour is dictated by the physics of thermally-excited domain walls. The basic concepts needed to understand and model single-chain magnets will also be reviewed.

description: Individual single-wall carbon nanotubes (SWNT) or small ropes of SWNTs with the same diameter have been characterised by Raman spectroscopy. Highly pure, length-selected SWNTs adsorbed onto substrates designed for surface-enhanced Raman spectroscopy were investigated with a Raman microscope. Various spectra, each with a distinct sharp peak in the radial breathing mode area and four C–C stretching modes could be observed. The modes also showed a strong variation in the relative intensities. In correlation with theoretical predictions this should establish Raman microscopy as a non-destructive nano-technological tool, capable of determining the diameter, symmetry and position of individual SWNTs.

description: Cowpea (Vigna unguiculata) plays an important role in sustainable food security and livelihood improvement in Sub-Saharan Africa (SSA). The crop is rich in phytonutrients and minerals, which are key in solving malnutrition and hunger crisis, a major challenge in SSA. However, physiological status, storage temperature and duration affect phytonutrient levels and postharvest life of the leafy vegetable. Despite the significant importance of cowpeas, the maturity and postharvest storage effects on quality of the leafy vegetable remains unrevealed. The aim of this study was to analyze the dynamics of phytonutrients in cowpea leaves during development under field conditions in Kenya and in storage. The total carbohydrates (glucose, fructose, sucrose and starch) were highest at 90 d after planting (105.9 ± 2.5 g kg-1) compared to 30, 60 and 120 d. The total Phenolics (Gallic acid equivalents) increased gradually with age up to 12.0 ± 0.2 g kg-1 by 120 d. Catechin equivalent flavonoids, trolox equivalent antioxidants (TEA) and chlorophyll were highest in concentrations at 60 d after planting with 8.0 ± 0.5 g kg-1, 26.19 ± 0.5 g kg-1 and 5.7 ± 0.4 g kg-1 respectively. Quercetin equivalent flavonoids and total carotenoids did not show significant changes with age, while mineral concentration dynamics were specific for each element. Storage of cowpea leaves at room temperature (50–55 % relative humidity) led to a stronger decline of phytonutrients after 4 d, but mostly they remained stable at cold storage (5 °C). Results of this study highlight the importance of developmental stage at harvest, storage conditions and duration for the optimal availability of phytonutrients in freshly consumed leaves and for postharvest management strategies.

title: Why say sorry? Intergroup apologies and the perpetrator perspective
Creators: name: Kristin Zaiser, Erica
Publisher: name: University of Kent
Year: 2023

description: This research focuses on the impact of apologies and reparations on members of the perpetrator group. Seven experiments across different contexts examined three possible outcomes for the perpetrator group: satisfaction with the act, negative feelings towards the victims, and support for future assistance. This dissertation argues that perpetrator group members are satisfied with an apologetic act for two reasons: the apology improves the image of their group; and it implies an obligation for victims to "get over" the issue (obligation shifting). Realistic power gains or losses for either group were unimportant to perpetrators but in the final experiment victim empowerment emerged as relating to perpetrator satisfaction in addition to obligation shifting and image improvement. Obligation shifting alone related to more negative feelings about the victims and predicted reduced support for further acts of assistance. Image improvement perceptions did not show these effects, and sometimes was related to less negative feelings about the victims. These relationships were causal (Experiment 5) and distinct from any desire to actually satisfy victims (Experiment 6). The first four experiments also tested differences between types of acts on the three outcome variables. When differences were found, obligation shifting and image perceptions mediated these relationships. Even more, if victims feel that obligation shifting is expected by perpetrators after an apology, they are less willing to forgive (Experiment 7). This research provides the first empirical investigation into the outcomes of apologies for perpetrator group members and the results underline the importance of image improvement and obligation shifting as factors in internal support for intergroup apologetic acts.

description: In the last decades, the optical adhesives have become highly promising due to their widespread applications in the numerous optical fields. There are outnumbered research studies about them and their numerous fields of application. One of these promising applications is the usage of self-written waveguides (SWW) which enable a rigid and low loss connection between two optical components. Nevertheless, there are not enough research studies about the temperature dependency of the optical transmission through the SWW that is inspected in this study. This master’s project is devoted to study the transmission of a laser beam by temperature through SWW created in the NOA 68 photopolymer medium. To verify the data from the experiment, a model is designed, simulated using the Multiphysics optical simulation software (COMSOL), and then, the simulation results are compared with the experimental data. Furthermore, the research studies do not propose anything for the durations of the internal- and external curing where the waveguide is attenuated highest that makes it very vital for the waveguide formation. This study removed the blurriness in the curing times and guide the scientists in establishing an efficient waveguide made out of NOAs. To achieve this goal, a thermal simulation of the waveguide is made, an SWW is formed, and the experimental results of the power output, and the refractive-index profile of the waveguide are analyzed. Then, the RIs of the SWW and its cladding are measured in the refractive-index profilometer and the results are used to make the simulation in the software.

description: We examine the N=1 super sinh-Gordon (SShG) model restricted into the half line through a reduction from the defect SShG model. The Bäcklund transformations are employed to generate one-, two- and three-soliton solutions as well as a class of breathers solution for this model. The parameters of such classical solutions are shown to satisfy some contraints in order to preserve both integrability and supersymmetry properties of the original bulk theory. Additionally, previous results are recovered when performing the purely bosonic limit.

description: In this work, we propose a novel adaptive reduced-rank strategy based on joint interpolation, decimation and filtering (JIDF) for large multiuser multiple-input multiple-output (MIMO) systems. In this scheme, a reduced-rank framework is proposed for linear receive processing and multiuser interference suppression according to the minimization of the bit error rate (BER) cost function. We present a structure with multiple processing branches that performs dimensionality reduction, where each branch contains a group of jointly optimized interpolation and decimation units, followed by a linear receive filter. We then develop stochastic gradient (SG) algorithms to compute the parameters of the interpolation and receive filters along with a low-complexity decimation technique. Simulation results are presented for time-varying environments and show that the proposed MBER-JIDF receive processing strategy and algorithms achieve a superior performance to existing methods at a reduced complexity.

Language learning from positive evidence, reconsidered: A simplicity-based approach

description: Children learn their native language by exposure to their linguistic and communicative environment, but apparently without requiring that their mistakes are corrected. Such learning from positive evidence has been viewed as raising logical problems for language acquisition. In particular, without correction, how is the child to recover from conjecturing an over-general grammar, which will be consistent with any sentence that the child hears? There have been many proposals concerning how this logical problem can be dissolved. Here, we review recent formal results showing that the learner has sufficient data to learn successfully from positive evidence, if it favours the simplest encoding of the linguistic input. Results include the ability to learn a linguistic prediction, grammaticality judgements, language production, and form-meaning mappings. The simplicity approach can also be scaled-down to analyse the ability to learn a specific linguistic constructions, and is amenable to empirical test as a framework for describing human language acquisition.

Novel loop-diagrammatic approach to QCD $θ$ parameter and application to the left-right model

description: When the QCD axion is absent in full theory, the strong $CP$ problem has to be explained by an additional mechanism, e.g., the left-right symmetry. Even though tree-level QCD $\barθ$ parameter is restricted by the mechanism, radiative corrections to $\barθ$ are mostly generated, which leads to a dangerous neutron electric dipole moment (EDM). The ordinary method for calculating the radiative $\barθ$ utilizes an equation $\bar θ= - \text{arg}\, \text{det}\, m_q^{\rm loop}$ based on the chiral rotations of complex quark masses. In this paper, we point out that when full theory includes extra heavy quarks, the ordinary method is unsettled for the extra quark contributions and does not contain its full radiative corrections. We formulate a novel method to calculate the radiative corrections to $\barθ$ through a direct loop-diagrammatic approach, which should be more robust than the ordinary one. As an application, we investigate the radiative $\barθ$ in the minimal left-right symmetric model. We first confirm a seminal result that two-loop level radiative $\barθ$ completely vanishes (corresponding to one-loop corrections to the quark mass matrices). Furthermore, we estimate the size of a non-vanishing radiative $\barθ$ at three-loop level. It is found that the resultant induced neutron EDM is comparable to the current experimental bound, and the expected size is restricted by the perturbative unitarity bound in the minimal left-right model.

description: The alloying effect on the lattice parameters, isostructural mixing enthalpies and ductility of the ternary nitride systems Cr1-xTMxN (TM=Sc, Y; Ti, Zr, Hf; V, Nb, Ta; Mo, W) in the cubic B1 structure has been investigated using first-principles calculations. Maximum mixing enthalpy due to large lattice mismatch in Cr1-xYxN solid solution shows a strong preference for phase separation, while Cr1-xTaxN exhibits a negative mixing enthalpy in the whole compositional range with respect to cubic B1 structured CrN and TaN, thus being unlikely to decompose spinodally. The near-to-zero mixing enthalpies of Cr1-xScxN and Cr1-xVxN are ascribed to the mutually counteracted electronic and lattice mismatch effects. Additions of small amounts of V, Nb, Ta, Mo or W into CrN coatings increase its ductility.

description: Azerbaijan is geographically located at the intersection of West and East. It has unequivocally made a choice towards innovation. The swift diversification of the economy into processing, industrial, and further into the informational sphere is a defining condition for the competitiveness of Azerbaijan’s sustainable development. The issue of selecting the necessary information and making optimal decisions based on it is particularly essential in various emergency situations. In the 21-st century it has become crucial to exercise local and regional control of the Caspian region environment's condition. This can be explained by the intensive development and exploitation of oil fields as well as by natural changes (sea level fluctuations in the coastal zone, etc.). At the same time, with the increasing volume of oil transportation through pipelines and with the help of oil tankers, anthropogenic pressure on the region will be steadily increasing. In this context, the development of new technologies and methodologies that provide information support for ecological observations (in particular, environmental audit and risk analysis), is of decisive importance. In this regard, remote sensing from orbiters exemplifies a powerful method of planetary exploration. Onboard sensors provide unique views of the Earth's surface combined with a large range. On the base of the above-mentioned facts, this paper is aimed at discussing several important features of aerospace monitoring of the oil pollution of the Caspian Sea surface using technologies of cognitive and expert systems.

description: The results of the analysis of radar studies of hail processes over the territories of Georgia and Azerbaijan on May 28 and July 13, 2019 are presented. Based on the values of the maximum size of hailstones in clouds, using the Zimenkov-Ivanov model, the expected sizes of hailstones falling on the earth's surface are calculated. The degree of damage to vineyards, wheat and corn, depending on the size of the hail, was determined by summarizing the known data on damage to these crops at different kinetic energy of hail and data on the average kinetic energy of hail of different magnitudes. Based on this compilation, regression equations were obtained for the relationship between the degree of damage to these crops and the size of hailstones, which have the form of a sixth degree of a polynomial. According to this equation, calculations were made of the degree of maximum damage to vineyards, wheat and corn along the trajectories of hail clouds over the territories of Georgia and Azerbaijan.

description: The information obtained through Arduino microcontroller is described in graphical dependencies in real-time mode of the result. When the crack is detected in the pipe, the maximum point of the recorded signal indicates on the diagram the part where the crack exists. Otherwise, the signal is described in the form of a straight line and indicates that no crack is found. The operator is able to determine any crack based on the signal recorded on the monitor. Due to the current leakage in the point of any crack the signal is transmitted to the Arduino microcontroller and, then, to the software. Based on the information received, the coordinate of the crack is found. So, since we obtain the information about the instantaneous displacement of the electrode with the encoder, we determine the coordinate of the crack according to the maximum value of the current leakage based on the diagram obtained.

description: Oil and gas pipes used in well operations are undergo to aggressive environments. In this case, corrosion wear of the thickness of their walls occurs, which leads to various difficulties. In order to assess the technical condition of well pipes, geophysical methods are used, one of which is the electromagnetic inspection method. The paper proposes a method for predicting the maximum loss of pipe thickness based on the results of electromagnetic inspection by the step values of the depth of immersion of the lower part of the pipe into the well. Based on the use of fuzzy regression with fuzzy input/fuzzy output, a method for assessing the level of impact of the main formation parameters on the technical condition of well pipes is proposed.
