description: We present a statistical study on parsec scale properties of a sample of Brigthest Cluster Galaxies (BCGs) in Abell Clusters. These data show a possible difference between BCGs in cool core clusters (two-sided parsec scale jets) and in non cool core clusters (one-sided parsec scale jet). We suggest that the two-sided morphology in cool core clusters could be due to the presence of mildly relativistic jets slowed down already at mas scale as consequence of the jet interaction with a dense surrounding medium.

description: Vela X is a pulsar wind nebula (PWN) associated with the active pulsar B0833-45 and contained within the Vela supernova remnant (SNR). A collimated X-ray filament ("cocoon") extends south-southwest from the pulsar to the center of Vela X. VLA observations uncovered radio emission coincident with the eastern edge of the cocoon and H.E.S.S. has detected TeV $γ$-ray emission from this region as well. Using XMM-\textit{Newton} archival data, covering the southern portion of this feature, we analyze the X-ray properties of the cocoon. The X-ray data are best fit by an absorbed nonequilibrium plasma model with a powerlaw component. Our analysis of the thermal emission shows enhanced abundances of O, Ne, and Mg within the cocoon, indicating the presence of ejecta-rich material from the propagation of the SNR reverse shock, consistent with Vela X being a disrupted PWN. We investigate the physical processes that excite the electrons in the PWN to emit in the radio, X-ray and $γ$-ray bands. The radio and non-thermal X-ray emission can be explained by synchrotron emission. We model the $γ$-ray emission by Inverse Compton scattering of electrons off of cosmic microwave background (CMB) photons. We use a 3-component broken power law to model the synchrotron emission, finding an intrinsic break in the electron spectrum at $\sim5 \times 10^{6}$ keV and a cooling break at $\sim$ 5.5 $\times 10^{10}$ keV. This cooling break along with a magnetic field strength of 5 $\times 10^{-6}$ G indicate that the synchrotron break occurs at $\sim$1 keV.

description: The nitridation of InP(1 0 0) surfaces has been studied using synchrotron radiation photoemission. The samples were chemically cleaned and then ion bombarded, which cleaned the surface and also induced the formation of metallic indium droplets. The nitridation with a Glow Discharge Cell (GDS) produced indium nitride by reaction with these indium clusters. We used the In 4d and P 2p core levels to monitor the chemical state of the surface and the coverage of the species present. We observed the creation of In-N and P-N bonds while the In-In metallic bonds decrease which confirm the reaction between indium clusters and nitrogen species. A theoretical model based on stacked layers allows us to assert that almost two monolayers of indium nitride are produced. The effect of annealing on the nitridated layers at 450 $^\circ$C has also been analysed. It appears that this system is stable up to this temperature, well above the congruent evaporation temperature (370 $^\circ$C) of clean InP(1 0 0): no increase of metallic indium bonds due to decomposition of the substrate is detected as shown in previous works [L. Bideux, Y. Ould-Metidji, B. Gruzza, V. Matolin, Surf. Interface Anal. 34 (2002) 712] studying the InP(1 0 0) surfaces.

description: Opening of a gap in the low-energy excitations spectrum affects the power-law singularity in the photon absorption spectrum $A(Ω)$. In the normal state, the singularity, $A(Ω)\propto [D/(Ω-Ω_{\rm th})]^α$, is characterized by an interaction-dependent exponent $α$. On the contrary, in the supeconducting state the divergence, $A(Ω)\propto (D/Δ)^α(Ω-\tildeΩ_{\rm th})^{-1/2}$, is interaction-independent, while threshold is shifted, $\tildeΩ_{\rm th}=Ω_{\rm th}+Δ$; the ``normal-metal'' form of $A(Ω)$ resumes at $(Ω-\tildeΩ_{\rm th})\gtrsim Δ\exp(1/α)$. If the core hole is magnetic, it creates in-gap states; these states transform drastically the absorption edge. In addition, processes of scattering off the magnetic core hole involving spin-flip give rise to inelastic absorption with one or several {\it real} excited pairs in the final state, yielding a structure of peaks in $A(Ω)$ at multiples of $2Δ$ above the threshold frequency. The above conclusions apply to a broad class of systems, e.g., Mott insulators, where a gap opens at the Fermi level due to the interactions.

Leveraging Labor Markets Policies to Promote Local Employment Creation
Creators: name: Chen, Yuhao
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: This dissertation studies two common labor policy tools to promote local employment. The first chapter investigates the effects of local business tax incentives on local employment and the potential spillovers. I find that while counties offering incentives experience a boost in industry employment following the opening of the incented establishments, the magnitude of job creation is about half of what was promised. I also find evidence of employment spillovers through agglomeration at the county level, but the effect size is small, as evidenced by the reported small increase in firm entry and lack of impact on wage earnings. The second chapter of the dissertation studies the impact of reduced unemployment insurance (UI) benefits in the State of Florida on unemployment and exit behavior among those eligible for UI benefits. I find reducing unemployment benefits leads to a 1.1 percentage point decline in unemployment rate. However, there is no evidence of increase in tendency of exiting from unemployment among those eligible for UI benefits. The findings suggest that the two labor policy tools commonly used to promote local employment may require more scrutiny to improve the effectiveness of labor policies.
A pedagogy for an inclusive cognitive environment for foreign students in academia

description: This scenario focuses on a major issue in globalized academia, namely the plight of foreign students, especially regarding the expectations of using language (English, more often) at the same level as native speakers.

The scenario presents a hypothetical research group composed of both native speakers and non-native speakers, and raises the question of what integrity means in terms of expectations and rules considering the discrepancy of English-language mastery.

The hypothetical scenario is followed by two key questions that all academic communities composed of a mixture of native and foreign students will benefit from reflecting on.
Two Composite Higgs Doublets: Is it the Low Energy Limit of a Natural Strong Electroweak Symmetry Breaking Sector ?

Year: 2009

description: In this paper, we construct an effective model that describes the electroweak symmetry breaking sector by means of composite Higgs-like scalars, following the ideas of Minimal Walking Technicolor (MWT). We argue that, because of the general failure of Extended Technicolor (ETC) to explain the mass of the top quark, it is necessary to introduce two composite Higgs bosons: one of them originated by a MWT-ETC sector and the other one produced by a Topcolor sector. We focus on the phenomenological differences between the light composite Higgs present in our model and the fundamental Higgs boson predicted by the Standard Model and their production at the LHC. We show that in this scheme the main production channel of the lighter Higgs boson are the associated production with a gauge boson and $WW$ fusion but not the gluon-gluon fusion channel which is substantially suppressed.

description: Patchy particles are an intriguing subject of study and indeed a model system in the field of soft matter physics. In recent years, patchy particle models have been applied to describe a wide variety of systems, including colloidal crystals, macromolecular interactions, liquid crystals, and nanoparticle assemblies. Given the importance of the topic, rationalizing and capturing the basic features of these models is crucial to their correct application in specific systems. In this study, we extend the ion-activated attractive patchy particles model previously employed to elucidate the phase behavior of protein solutions in the presence of trivalent salts. Our extension incorporates the effect of repulsion between unoccupied and occupied binding sites, depicted as patches. Furthermore, we examine the influence of model parameters on the liquid-vapor coexistence region within the phase diagram, employing numerical methods. A deeper understanding of this model will facilitate a better comprehension of the effects observed in experiments.

description: We present an evaluation of the running coupling constant and the quark mass renormalization factor for $N_f=2+1$ QCD. The Schrödinger functional scheme is used as the intermediate scheme to carry out non-perturbative running from the low energy region, where physical input is introduced, to deep in the high energy perturbative region, where conversion to the ${\ovl{\rm MS}}$ scheme is safely performed. For numerical simulations we adopted Iwasaki gauge action and non-perturbatively improved Wilson fermion action with the clover term. Seven renormalization scales are used to cover from low to high energy region and three lattice spacings to take the continuum limit at each scale. Physical inputs are introduced from the previous $N_f=2+1$ simulation of the CP-PACS/JL-QCD collaboration, which covered the up-down quark mass range heavier than $m_π\sim 500$ MeV, and that of PACS-CS collaboration for much lighter quark masses down to $m_π=155$ MeV.

The Impact of Wetland Biogeochemistry and Hydraulic Loading on Tile Drainage Nutrient Removal Efficiency
Creators: name: Izadmehr, Mahsa
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: Nutrient releases from agriculture represent one of the major sources of nitrogen (N) and phosphorus (P) loading to the environment. Excess N and P can lead to deleterious effects in receiving waters, including eutrophication, species disruption, and aquatic hypoxia. One promising technology for reducing such releases is the use of constructed wetlands to remove primarily N through stimulated denitrification. More widescale adoption of this technology will require a better understanding of what limits N removal efficiencies. To address this knowledge gap, I have studied nutrient dynamics in two constructed wetlands to capture and treat agricultural tile drainage installed in Bureau County, Illinois. I analyzed inlet and outlet NO3--N concentration and sediment organic matter (OM) concentrations during wetlands development and operations. To help understand the nitrate removal process in the system, I characterized the hydraulic loading and performed tracer studies to measure residence time. These data used to determine mixing and short-circuiting, a process that can create dead zones and that impacts N removal efficiencies. I also studied the denitrifying microbial community structure in the wetland. Both constructed wetlands N removal efficiency improved over time by location, over the years, and over seasons with the minimum accumulated mass removal of 825 kg NO-3-N per year for each wetland. Species diversity and concentrations increased as labile OM increased, and the denitrifying community was largely gone following the sediment drying period, concomitant with a significant decrease in labile OM.

description: In this Letter, weak turbulence theory is used to investigate interactions among Alfven waves and fast and slow magnetosonic waves in collisionless low-beta plasmas. The wave kinetic equations are derived from the equations of magnetohydrodynamics, and extra terms are then added to model collisionless damping. These equations are used to provide a quantitative description of a variety of nonlinear processes, including "parallel" and "perpendicular" energy cascade, energy transfer between wave types, "phase mixing," and the generation of back-scattered Alfven waves.

Becoming Symptom Notation: A Study of Choreography for Mad and Hidden Disability Symptomologies

Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: As a Mad performance artist working within Chicago’s disability arts and culture scene, I’ve taken notice of an under-representation of disabled artists and dancers who identify as Mad or as having hidden disabilities. The critical recognition of physically integrated dance, which centers people with and without disabilities together, has paved the way for genres of disability dance to consider inclusivity and the aesthetic value of impairments in performance. I imagined how mental and hidden bodily “movements” might be translated into a form of its own, where symptoms from unrecognized disabilities could be projected through the physical body. Dance and music notation practices offer unique capabilities for translation that involve concrete systems of recording, interpretation, and reperformance using sign-oriented languages. In thinking of the possibilities of codifying symptoms, several lines of inquiry emerge: How does drawing from pre-existing systems of notation support the configuration of an arts-based process designed for hidden disabilities? How might notation practices serve people with hidden disabilities in identity formation, self-knowledge, and empowerment? Using auto/ethnographic approaches, this thesis follows the trajectory of Symptom Notation, a participatory, ‘cripped’ system of dance notation that translates symptoms into choreographic gestures through the use of symbols. In contrast to dominant pathologizing practices of “reading” symptoms, Symptom Notation reclaims symptoms as essential sites of self with generative and collaborative potential, arguing that the knowledge produced from symptomatic experiences creatively contribute to identity and community formation. Two performance art projects, Psychosis Journal (2018) and unbecoming hiding place (2019), function as case studies that visualize the motivations, doubts, and experimentations behind Symptom Notation’s becomings, in reflection of its shift from a private to communal method of self-exploration. Symptom Notation aims to address issues specific to hidden disability experiences, such as the concept of “passing”, to effectively bridge the self-uncovering process with the very politics that impose this category. It is through this project that self-becoming (and the subsequent unbecoming of Mad and hidden disability’s “invisibility” factor) is continuously enacted not only in search of a futurity for which people with hidden disabilities thrive, but in a reimagined scope of disability dance.

description: In neutrino oscillation with non-standard interactions (NSI) the system is enriched with CP violation caused by phases due to NSI in addition to the standard lepton Kobayashi-Maskawa phase δ. In this paper we show that it is possible to disentangle the two CP violating effects by measurement of muon neutrino appearance by a near-far two detector setting in neutrino factory experiments. Prior to the quantitative analysis we investigate in detail the various features of the neutrino oscillations with NSI, but under the assumption that only one of the NSI elements, ε_{e μ} or ε_{e τ}, is present. They include synergy between the near and the far detectors, the characteristic differences between the ε_{e μ} and ε_{eτ} systems, and in particular, the parameter degeneracy. Finally, we use a concrete setting with the muon energy of 50 GeV and magnetized iron detectors at two baselines, one at L=3000 km and the other at L=7000 km, each having a fiducial mass of 50 kton to study the discovery potential of NSI and its CP violation effects. We demonstrate, by assuming 4 \times 10^{21} useful muon decays for both polarities, that one can identify non-standard CP violation down to | epsilon_{e μ} | \simeq \text{a few} \times 10^{-3}, and | ε_{e τ} | \simeq 10^{-2} at 3σCL for θ_{13} down to \sin^2 2θ_{13} = 10^{-4} in most of the region of δ. The impact of the existence of NSI on the measurement of δand the mass hierarchy is also worked out.

description: We show that all multi-partite pure states can, under local operations, be transformed into bi-partite pairwise entangled states in a "lossless fashion": An arbitrary distinguished party will keep pairwise entanglement with all other parties after the asymptotic protocol - decorrelating all other parties from each other - in a way that the degree of entanglement of this party with respect to the rest will remain entirely unchanged. The set of possible entanglement distributions of bi-partite pairs is also classified. Finally, we point out several applications of this protocol as a useful primitive in quantum information theory.

description: Exoplanet exploration has revealed that many$\unicode{x2013}$perhaps most$\unicode{x2013}$terrestrial exoplanets formed with substantial H$_2$-rich envelopes, seemingly in contrast to solar system terrestrials, for which there is scant evidence of long-lived primary atmospheres. It is not known how a long-lived primary atmosphere might affect the subsequent habitability prospects of terrestrial exoplanets. Here, we present a new, self-consistent evolutionary model of the transition from primary to secondary atmospheres. The model incorporates all Fe-C-O-H-bearing species and simulates magma ocean solidification, radiative-convective climate, thermal escape, and mantle redox evolution. For our illustrative example TRAPPIST-1, our model strongly favors atmosphere retention for the habitable zone planet TRAPPIST-1e. In contrast, the same model predicts a comparatively thin atmosphere for the Venus-analog TRAPPIST-1b, which would be vulnerable to complete erosion via non-thermal escape and is consistent with JWST observations. More broadly, we conclude that the erosion of primary atmospheres typically does not preclude surface habitability, and frequently results in large surface water inventories due to the reduction of FeO by H$_2$.

The Role of Reappraisal on Emotional Outcomes Following Instagram Use

Year: 2021
Subjects: Uncategorized

description: This mixed methods study examined the effectiveness of a novel video manipulation using reappraisal as an emotion regulation strategy to improve the emotional experiences of Instagram users. In the quantitative section, three hypotheses were proposed: (1) Mood will improve more from pretest to posttest for the reappraisal participants compared to control participants. (2) Self-esteem scores will increase more from pretest to posttest for the reappraisal participants compared to control participants. (3) Loneliness score will decrease more from pretest to posttest for the reappraisal participants compared to control participants. In the qualitative section, semi-structured interviews were conducted with participants after their Instagram use to gain a deeper understanding of their emotional experiences. Two hundred forty-seven participants were recruited into this two-semester study (Fall 2020, Spring 2021). Participants in the treatment condition watched a video normalizing emotional experiences on Instagram, while control participants watched a video about the history of Instagram. None of the hypotheses were supported. For the variable of self-esteem, participants scored higher on self-esteem at posttest compared to pretest. The qualitative findings provided rich context explaining participants’ emotional experiences. Using transcendental phenomenology (Moustakas, 1994), seven themes were identified after synthesizing qualitative data from 50 participants. These themes were positive emotion, negative emotion, social comparison, self-esteem, reappraisal, awareness of highlight reel, and attention to likes, comments, and followers. Implications from the qualitative findings include identifying specific content that improved or worsened participants’ emotions and how future researchers can target new ways to improve participants’ experiences.

description: New limits on the weak mixing angle and on the electron neutrino effective charge radius in the low energy regime, below 100 MeV, are obtained from a combined fit of all electron-(anti)neutrino electron elastic scattering measurements. We have included the recent TEXONO measurement with a CsI (Tl) detector. Only statistical error of this measurement has been taken into account. Weak mixing angle is found to be sin^2 theta_W = 0.255 +0.022 -0.023. The electron neutrino effective charge radius squared is bounded to be r^2 = (0.9 +0.9 -1.0) x 10^{-32} cm^2. The sensitivity of future low energy neutrino experiments to nonstandard interactions of neutrinos with quarks is also discussed.

description: In this paper we present the structural properties and morphology of galaxies in the central region of the Coma Cluster brighter than $19.5^m$ in the $F814W$ band. from the HST/ACS Coma Cluster Treasury Survey. Using mainly spectroscopic redshifts, we find 132 members from our sample of 219 galaxies. In our sample of 132 members, we find 51 non-dwarfs and 81 dwarfs and amongst our 32 non-members, we find 4 dwarfs and 28 non dwarfs. We do not have redshifts for the remaining 55 galaxies. We present bulge-disc decomposition of the sample using GALFIT and obtain parameters for our sample. Using visual inspection of residuals, we do a a morphological classification of the galaxies. We studied the relation of morphological types with Bulge to Total Light Ratio ($B/T$), color magnitude relation (CMR), Sérsic index ($n$), Kormendy relation and cross-correlations between these parameters for the bulges and galaxies. %Of the members, six galaxies have been classified as E/SBO on the basis of their residuals and contour maps which show a boxy/peanut bulge at the center of galaxy. So we have little confusion to classify the elliptical or SBO, we have given E/SBO. This work helps us understand important relations between various parameters like $B/T$, color and $n$ as well as insights into the merger history of these galaxies in terms of their positions in the Kormendy Diagram and their Sérsic indices. Using statistical methods, we find that the there are significantly more E/SO, ESOs galaxies in the member population compared to non-members.

Control of Cell Culture Microenvironment Using Programmable Systems
Creators: name: Adiraj Iyer, Maheshwar
Publisher: name: University of Illinois at Chicago
Year: 2021
Subjects: Uncategorized

description: Control of cell culture microenvironment is a useful technique to close the experimental gap between in vitro and in vivo experimental models. The increasing popularity of microfluidic methods necessitates the study of PDMS’ tendency to absorb hydrophobic molecules into the polymer matrix and thus their apparent reduction in concentration can cause inconsistencies in assay results performed in PDMS systems. This absorptive behavior of PDMS can be studied using fluorescent dyes that act as model molecules to simulate drug/protein behavior and can be used to understand the effects of hydrophobicity of PDMS in microfluidic applications. Control of culture microenvironment also plays an important role when studying the effects of gasotransmitters in vitro. Conventional methods using H2S, and CO precursor molecules cause the generation of inconsistent and unreliable data due to the precursor-dependent release characteristics of gasotransmitter exposure. To alleviate this, and to establish a standardized experimental platform to stabilize exposures of short-lived gasotransmitters to more experimentally relevant timescales and concentrations, an Arduino-controlled was developed that made possible the pilot-scale experiments of multi-hour and multi-day exposures of in vitro models to gasotransmitters, as well as multi-gasotransmitter experiments into the same in vitro system. NaSH, when used as a precursor molecule results in short-lived exposure on the order of a few minutes, but that could be stabilized and extended to multiple hours and days when coupled with an active control system that regulated the concentration and temporal profiles of H2S and CO treatment. The tailored gasotransmitter-delivery also enabled the study of their concentration dependent physiological effects in vitro along with the novel ability to control multiple gasotransmitters. The active control system of gasotransmitter delivery also enables dose control with delivery profiles that are not currently possible. Exploratory in vitro studies are done with the active dosing system used for high throughput studies as well as dose-dependent ROS response studies. Cell viability of A549 cells in response to treatment with multiple gasotransmitters was quantified as downstream effects of exposure to ROS in a combinatorial scheme.

Interplanetary magnetic field, solar wind and geomagnetic micropulsation

description: Micropulsation signals recorded at the mid-latitude station, Salston, Alberta, are compared with simultaneous Explorer 34 observations of the interplanetary field and plasma. The analysis is divided into two parts. First, a study of the interplanetary parameters controlling Pc3-4 activity is made, and second, spectra of upstream waves and continuous micro-pulsations are compared. A case by case study reveals that Pc3 and Pc4 occurrence is determined by the interplanetary field direction. Pc4 requires a field direction within 30° of the Earth-Sun line, while Pc3 takes place for a wider range of field latitudes and azimuths. On a time scale of the order of hours, the amplitude of Pc3-4 continuous pulsations correlates with the solar wind velocity. Large amplitude events associate with high speed solar wind, while small amplitude events correlate with low speed solar wind. Three dimensional distributions of Pc3 and Pc4 versus the interplanetary field direction are calculated. The distributions are then corrected for the amplitude of the signal and further normalised by the IMF distribution. The resulting distributions show that the field direction-control of Pc3-4 activity is net a result of the IMF distribution, and further, the field direction is also an amplitude-control of these continuous pulsations. They show that Pc4 is equally likely for toward and away sectors, while Pc3 exhibits a significant preference for toward sectors. Finally power spectra of upstream waves are compared with spectra of continuous pulsations. It is found that the spectra of Pc2-4 continuous pulsations are determined by the spectral content of upstream waves. On a time scale of the order of half an hour, the micropulsation spectrum correlates with the transverse components spectra of the upstream waves. On a shorter time scale, the micropulsation spectrum is determined by the peaks, transverse or compressional, that carry the roost power in space. Finally, the spectra of upstream waves and micropulsations are consistent with the existence of fundamental waves in space.

description: We carry out a systematic study of interferometry radii in ultrarelativistic heavy-ion collisions within a two-dimensional transport model. We compute the transverse radii R_o and R_s as a function of p_t for various values of the Knudsen number, which measures the degree of thermalization in the system. They converge to the hydrodynamical limit much more slowly (by a factor 3) than elliptic flow. This solves most of the HBT puzzle for central collisions: R_o/R_s is in the range 1.1-1.2 for realistic values of the Knudsen number, much closer to experimental data ($\simeq 1$) than the value 1.5 from hydrodynamical calculations. The p_t dependence of R_o and R_s, which is usually said to reflect collective flow, also has a very limited sensitivity to the degree of thermalization. We then study the azimuthal oscillations of R_o, R_s, and R_{os} for non central collisions. Their amplitudes depend little on the Knudsen number, and reflect the eccentricity of the overlap area between the two nuclei.

On the group theoretical approach to relativistic wave equations for arbitrary spin

description: Formulating a relativistic equation for particles with arbitrary spin remains an open challenge in theoretical physics. In this study, the main algebraic approaches used to generalize the Dirac and Kemmer Duffin equations for particles of arbitrary spin are investigated. It is proved that an irreducible relativistic equation formulated using spin matrices satisfying the commutation relations of the anti-de Sitter group leads to inconsistent results, mainly as a consequence of violation of unitarity and the appearance of a mass spectrum that does not reflect the physical reality of elementary particles. However, the introduction of subsidiary conditions resolves the problem of unitarity and restores the physical meaning of the mass spectrum. The equations obtained by these approaches are solved and the physical nature of the solutions is discussed.

description: We show that Polchinski equations in the D--dimensional matrix scalar field theory can be reduced at large $N$ to the Hamiltonian equations in a (D+1)-dimensional theory. In the subsector of the $\Tr ϕ^l$ (for all $l$) operators we find the exact form of the corresponding Hamiltonian. The relation to the Holographic renormalization group is discussed.

description: We consider a quantum linear oscillator coupled at an arbitrary strength to a bath at an arbitrary temperature. We find an exact closed expression for the oscillator density operator. This state is non-canonical but can be shown to be equivalent to that of an uncoupled linear oscillator at an effective temperature T_{eff} with an effective mass and an effective spring constant. We derive an effective Clausius inequality delta Q_{eff} =< T_{eff} dS, where delta Q_{eff} is the heat exchanged between the effective (weakly coupled) oscillator and the bath, and S represents a thermal entropy of the effective oscillator, being identical to the von-Neumann entropy of the coupled oscillator. Using this inequality (for a cyclic process in terms of a variation of the coupling strength) we confirm the validity of the second law. For a fixed coupling strength this inequality can also be tested for a process in terms of a variation of either the oscillator mass or its spring constant. Then it is never violated. The properly defined Clausius inequality is thus more robust than assumed previously.

description: In 1962 Charles Hartshorne published a modal logic proof formalizing Anselm of Canterbury's ontological argument for the necessary existence of God. This article presents Kurt Gödel's notes on this proof which have now been discovered in his Nachlass among other theological material, and discusses possible influences on the development of Gödel's own ontological proof. To complete the picture, strong connections between Anselm of Canterbury's and Gödel's conceptions of God and his positive properties are pointed out.
Classification of Ge hut clusters in the arrays formed by molecular beam epitaxy at low temperatures on the Si(001) surface

description: Morphological investigations and classification of Ge hut clusters forming the arrays of quantum dots on the Si(001) surface at low temperatures in the process of the ultrahigh vacuum molecular beam epitaxy have been carried out using in situ scanning tunnelling microscopy. Two main species of Ge hut clusters composing the arrays - pyramidal and wedge-shaped ones - have been found to have different atomic structures. The inference is made that shape transitions between pyramids and wedges are impossible. The nucleation probabilities of pyramids and wedges equal 1/2 at the initial stage of the array formation. The wedges become the dominating species as the amount of the deposited germanium is increased. A fraction and a density of the pyramids in the arrays are rapidly decreased with the growth of Ge coverage. The derivative types of the clusters - obelisks (or truncated wedges) and accreted wedges - have been revealed and investigated for the first time, they have been found to start dominating at high Ge coverages. The obelisks originate from the wedges as a result of their height limitation and further growth of trapezoid facets. The apexes of the obelisks are formed by sets of the parallel (001) ridges. The uniformity of the cluster arrays have been evidenced to be controlled by the length of the wedge-like clusters. At low growth temperatures (360C) nucleation of new clusters is observed during the array growth at all values of Ge coverage except for a particular point at which the arrays are more uniform than at higher or lower coverages. At higher (530C) temperatures cluster nucleation has not been observed after the initial stage of the array formation.

Imagining Korean unification, people and state

description: Unification is proclaimed as the national mission by both Koreas and forms the bedrock for the south’s political legitimacy. However, this national mission holds increasing disenchantment among south Koreans today. The weakening of ethnic sentiments, the rise of a new nationalism and the pressures of everyday life see unification peripheralised among the public. Given current President Moon’s unprecedented steps towards confederation, this thesis explores how unification is imagined by south Koreans in Seoul and the state’s role therein. It is based on ethnographic methods of participant observation and semi-structured interviews with south Koreans and north Korean refugee-defectors. Using an historicist and hermeneutic approach to analyse and problematise political imaginaries around unification, this thesis addresses: a) the state’s predicament in accounting for shifting national sentiments when crafting its unification pitch; and, b) how the south Korean people - dissonantly stirred by ethnic sentiments but increasingly apathetic to unification due to its fiscal costs and potential refugee influx - reconcile this ambivalence. Ultimately, this thesis will provide an interpretation of the inner worlds of a prima facie unwavering national mission. Although the latter seems to be becoming increasingly closer under President Moon, it is – in fact – unimaginable after more than seventy years of division.

description: In this paper, it is proved that, if a toric ideal possesses a fundamental binomial none of whose monomials is squarefree, then the corresponding semigroup ring is not very ample. Moreover, very ample semigroup rings of Lawrence type are discussed. As an application, we study very ampleness of configurations arising from contingency tables.

description: Dynamic loadings produce high stress waves leading to the spallation of ductile materials such as aluminum, copper, magnesium or tantalum. The main mechanism used herein to explain the change of the number of cavities with the stress rate is nucleation inhibition, as induced by the growth of already nucleated cavities. The dependence of the spall strength and critical time with the loading rate is investigated in the framework of a probabilistic model. The present approach, which explains previous experimental findings on the strain-rate dependence of the spall strength, is applied to analyze experimental data on tantalum.
