description: The recovery of an exoplanet's atmospheric parameters from its spectrum requires accurate knowledge of the spectral errors and covariances. Unfortunately, the complex image processing used in high-contrast integral-field spectrograph (IFS) observations generally produces spectral covariances that are poorly understood and often ignored. In this work, we show how to measure the spectral errors and covariances and include them self-consistently in parameter retrievals. By combining model exoplanet spectra with a realistic noise model generated from GPI early science data, we show that ignoring spectral covariance in high-contrast IFS data can both bias inferred parameters and lead to unreliable confidence regions on those parameters. This problem is made worse by the common practice of scaling the $χ^2$ per degree of freedom to unity; the input parameters then fall outside the $95\%$ confidence regions in as many as ${\sim}80\%$ of noise realizations. The biases we observe can approach the typical levels of precision achieved in high-contrast spectroscopy. Accounting for realistic priors in fully Bayesian retrievals can also have a significant impact on the inferred parameters. Plausible priors on effective temperature and surface gravity can vary by an order of magnitude across the confidence regions appropriate for objects with weak age constraints; priors for objects with good age constraints are dominated by modeling uncertainties. Our methods are directly applicable to existing high-contrast IFSs including GPI and SPHERE, as well as upcoming instruments like CHARIS and, ultimately, WFIRST-AFTA.

description: Spherical nanoclusters and nanoparticles are rising materials whose functional design provides many useful applications ranging from catalysis, molecular sensing, gas storage to drug targeting and delivery. Here, we develop phenomenological crystallization theory of such spherical structures with octahedral symmetries O and O_h. Within the developed theory, we propose a method, which is based on constructing irreducible octahedral density functions and allows to predict the positions of structural units in the spherical nanoobjects. The proposed theory explains the structures of the simplest known metal nanoclusters, some metal-organic polyhedra and membrane protein polyhedral nanoparticles, and also predicts more complex chiral spherical structures and achiral assemblies characterized by the geometry of semiregular polyhedra. A relationship between the constructed irreducible octahedral functions and spherical lattices, obtained by mapping a plane hexagonal order onto a spherical surface through an octahedron net, is discussed as well.

description: Polarized light-matter interactions are mathematically described by the Mueller matrix (MM)-valued polarized bidirectional reflectance distribution function (pBRDF). A pBRDF is parameterized by 16 degrees of freedom that depend upon scattering geometry. A triple degenerate (TD) MM assumption reduces the degrees of freedom to eight: one for reflectance, six for non-depolarizing properties, and one for depolarization. When the non-depolarizing dominant process is known or assumed (e.g. Fresnel reflection), the degrees of freedom are further reduced to two. For a given material, if the TD model is appropriate and the dominant non-depolarizing process is known, then these two degrees of freedom can be estimated from as few as two polarimetric measurements. Thus, the MM can be extrapolated from a reduced number of measurements. The primary contribution of this work is the development and demonstration of a linear estimator for a MM's dominant eigenvalue (i.e. single depolarization parameter) which requires fewer measurements than a full MM reconstruction. MM extrapolations from single snapshot acquisitions with a Sony Triton 5.0MP Polarization Camera are performed at 30 acquisition geometries and two wavelengths on an ensemble of LEGO bricks treated to have varying surface roughness. These extrapolated MMs are compared to MMs reconstructed from a complete dual rotating retarder (DRR) Mueller imaging polarimeter. The flux error mean and mode are 11.06% and 1.03%, respectively, despite a 10x reduction in the number of polarimetric measurements.

description: During the Chinese Eastern Railway construction (1897-1903), a large amount of areas attached to railway station-located areas had been constructed and developed constantly, which therefore facilities the emergence of new type morphology of cluster arising from the railway in northeast China. And the towns’ morphology of this period had had the profound influence on the subsequent the towns’ development in northeast China. In this research, the author himself went to St. Petersburg in Russia and to check and collect files in Russian National History Archives, from which a large amount of basic files about city construction during the period of the construction of Chinese Eastern Railway have been generated; then, based on the above materials (ages and number), the research period (construction of Chinese Eastern Railway 1897-1903) , objects (railway stations along the main lines of Chinese Eastern Railway:) and sample (Station Hailar and Suifenhe )are determined; Thirdly, the historic planning drawings and towns’ construction for two stations are translated to extract the planning information ,earlier city construction, social economy development , location features, land layout, texture of street profile, street transport, buildings’ texture, landscape greening and other basic elements of towns’ morphology. Two towns are compared to conclude the typical structural pattern and morphology. Ultimately, Russian style station in Suifenhe City is taken to conduct field research and empirical analysis and explicit the conservation content of historic features as well as propose the conservation ides depending on the principles of completeness and authenticity. After hundreds of years, the Russian style stations during the Chinese Eastern Railway have developed into to the commercial centers, which dominate in the modern city. Although the features of earlier Russian style stations have been broken, these centers still demonstrate strong sense of environment and landscape as Russian style colonial city. This research intends to explore the planning content of earlier stations to restores the planning elements of earlier cities with the ultimate aim to reveal the historical landscape of the towns, which is greatly significant to the conservation of urban historical features.

description: We investigate production of primordial black holes from first-order electroweak phase transition in the framework of the nearly aligned Higgs effective field theory, in which non-decoupling quantum effects are properly described. Since the mass of such primordial black holes is evaluated to be about $10^{-5}$ of the solar mass, current and future microlensing observations such as Subaru HSC, OGLE, PRIME and Roman Space Telescope may be able to probe the electroweak phase transition. We study parameter regions where primordial black holes can be produced by the first-order electroweak phase transition, and explore their detectability at these observations. Complementarity of primordial black hole observations, gravitational wave observations and collider experiments is also discussed for testing the nature of the electroweak phase transition.

description: This work is mainly concentrated on the development of new versatile ligand based on N,N’-disubstituted-1,8-diaminonaphthalene (1,8-DAN) for main group chemistry. Therefore, our initial efforts were made on the design of new ligand scaffold by using 1,8-DAN. Following that, new ligand family supported by 1,8-DAN was applied as ligands to main group elements (B, Al, In, Ga, and C). Furthermore, six-membered ring carbenes which are derived from the reaction between N,N’-disubstituted-1,8-diaminonaphthalene and carbon are also investigated. In addition, the stable carbenes were implied as a new ligand system for palladium, leading to the formation of metal ligand complexes. Therefore, the synthesis and reactivity of these complexes are also reported. Chapter I gives an explanation on the basic concepts in terms of the ligand designs and reports the reasons why N,N’-disubstituted-1,8-diaminonaphthalene has been chosen as the framework of for these ligands. Chapter II presents the approach to synthesize ligands depending on the substitution. Regarding this, three methods were successfully used: reductive amination, application of acyl halide followed by reduction, and copper catalyzed C-N coupling reactions. Chapter III describes the reactions between the N,N’-disubstituted-1,8-diaminonaphthalene and main group elements B, Al, Ga, and In in 13 group. In this chapter, a variety of mononuclear and dinuclear complexes are investigated and fully characterized. Furthermore, some computational studies are also reported for the comparison with experimental results. Chapter IV deals with new ligand family, carbene, which is derived from N,N’-disubstituted-1,8-diaminonaphthalene. Therefore, not only fundamental concepts for the NHC (N-heterocyclic carbene) are discussed but also synthetic pathways are introduced. Moreover, interesting features of free carbene are presented as well. Chapter V reports the potential of this new carbene ligand family as ligands for transition metal compound, especially, Pd(II) compounds. Several different pathways for synthesizing the desired metal carbene complexes are presented.

description: We investigate the relationship between environment, morphology, and the star formation rate -- stellar mass relation derived from a sample of star-forming galaxies (commonly referred to as the `star formation main sequence') in the COSMOS field from 0 < z < 3.5. We constructed and fit the FUV--FIR SEDs of our stellar mass-selected sample of 111,537 galaxies with stellar and dust emission models using the public packages MAGPHYS and SED3FIT. From the best fit parameter estimates, we construct the star formation rate -- stellar mass relation as a function of redshift, local environment, NUVrJ color diagnostics, and morphology. We find that the shape of the main sequence derived from our color-color and sSFR-selected star forming galaxy population, including the turnover at high stellar mass, does not exhibit an environmental dependence at any redshift from 0 < z < 3.5. We investigate the role of morphology in the high mass end of the SFMS to determine whether bulge growth is driving the high mass turnover. We find that star-forming galaxies experience this turnover independent of bulge-to-total ratio, strengthening the case that the turnover is due to the disk component's specific star formation rate evolving with stellar mass rather than bulge growth.

Publisher: name: No Publisher Supplied
Year: 2022

description: Purpose: The adverse effects of opioid-induced androgen deficiency (OPIAD) in men on chronic opioids continue to rise with the growing aging population and the increased rate of opioid prescriptions. OPIAD affects diabetes mellitus, hyperlipidemia, obesity, erectile dysfunction, osteoporosis, anemia, depression, and cardiovascular disease. Providers can improve care by screening for androgen deficiency in men on chronic opioids and referring men who test positive for OPIAD for evaluation of hypogonadism. The purpose of this project was to improve the identification of the patients with androgen deficiency secondary to chronic opioid use and refer them for follow-up evaluation of OPIAD. Methodology: This quality improvement pilot project used the ADAM questionnaire to identify androgen deficiency in men on chronic opioids. Men who screened positive were referred for further evaluation of OPIAD. A follow-up phone survey determined the benefit of the ADAM in screening men with OPIAD and patient satisfaction with the project. The survey of the provider assessed the efficacy and sustainability of the project. Results: Ten men participated in the screening for OPIAD, and 9 men (90%) screened positive for androgen deficiency. Of those who screened positive, 8 completed the followed-up phone survey, and 7 (87.6%) reported follow-ups with their provider for evaluation of OPIAD. Seven Two individuals (33.3%) had changes to their treatment regimen or received a referral to an endocrinologist. Participants’ average satisfaction score with the project was 4.6 out of 5, with a median satisfaction score of 5. Implications for Practice: This pilot project showed a high prevalence of androgen deficiency in men on chronic use of opioids at this clinical site. The results indicate the usefulness of the ADAM questionnaire in identifying OPIAD in men on chronic opioids. Integrating the ADAM questionnaire in practice enables the detection and treatment of OPIAD.

description: Background: Current cesarean delivery (CD) rates in many industrialized countries are well above the recommended rates. Objective: The overall goal of this thesis was to identify sources for unnecessary CD. Specific objectives were to: 1) analyze the leading indications for CD and their associations with neonatal outcomes; 2) compare adverse birth outcomes between elective primary cesarean delivery (EPCD) and trial of labor after vaginal birth (TOLAV), and between elective repeat cesarean delivery (ERCD) and trial of labor after cesarean birth (TOLAC); and 3) assess the cost-effectiveness of ERCD and TOLAC. Methods: A retrospective cohort study was conducted. Leading indications for CD were analyzed and risks of neonatal outcomes between “soft” indications and “hard” indications were compared first, using 2006 to 2013 Better Outcomes and Registry Network Ontario data. A pair of analyses: comparing risks of adverse birth outcomes between EPCD and TOLAV and between ERCD and TOLAC, were then conducted using United States 2005 to 2010 birth registration data. Analysis were performed using logistic regression and propensity score matching models. Finally, a cost-effectiveness analysis between ERCD and TOLAC was performed. Results: The single largest contributor for overall CD was ERCD (34.3%) and for primary CD was dystocia (31.9%) in Ontario. Compared with infants of mothers with CD for “hard” indications, the risks of Apgar score <7 at 5 minutes for infants of mothers with CD for non-reassuring-fetal-status was increased, while the risks of Apgar score <7 at 5 minutes and neonatal death for infants of mothers with ERCD and dystocia were decreased. Compared with infants of mothers who underwent TOLAV, infants of mothers who underwent EPCD were more likely to require antibiotics and ventilation support, but less likely to have birth injury. On the other hand, compared with infants of mothers who underwent TOLAC, infants of mothers who underwent ERCD were less likely to require antibiotics and ventilation support. ERCD was similar to the TOLAC birth option in terms of cost effectiveness. Conclusions: Tight up criteria for “soft” indications such as labor dystocia could result in substantial reduction in CD without harming the infants.

description: Coronal holes (CHs) are the source of high-speed streams (HSSs) in the solar wind, whose interaction with the slow solar wind creates corotating interaction regions (CIRs) in the heliosphere. Whenever the CIRs hit the Earth, they can cause geomagnetic storms. We develop a method to predict the strength of CIR/HSS-driven geomagnetic storms directly from solar observations using the CH areas and associated magnetic field polarity. First, we build a dataset comprising the properties of CHs on the Sun, the associated HSSs, CIRs, and orientation of the interplanetary magnetic field (IMF) at L1, and the strength of the associated geomagnetic storms by the geomagnetic indices Dst and Kp. Then, we predict the Dst and Kp indices using a Gaussian Process model, which accounts for the annual variation of the orientation of Earth's magnetic field axis. We demonstrate that the polarity of the IMF at L1 associated with CIRs is preserved in around 83% of cases when compared to the polarity of their CH sources. Testing our model over the period 2010-2020, we obtained a correlation coefficient between the predicted and observed Dst index of R = 0.63/0.73, and Kp index of R = 0.65/0.67, for HSSs having a polarity towards/away from the Sun. These findings demonstrate the possibility of predicting CIR/HSS-driven geomagnetic storms directly from solar observations and extending the forecasting lead time up to several days, which is relevant for enhancing space weather predictions.

description: A dual-phase xenon time-projection chamber was built at Nikhef in Amsterdam as a direct dark matter detection R&D facility. In this paper, the setup is presented and the first results from a calibration with a $^{22}$Na gamma-ray source are presented. The results show an average light yield of (5.6 $\pm$ 0.3) photoelectrons/keV (calculated to 122 keV and zero field) and an electron lifetime of (429 $\pm$ 26) $μ$s. The best energy resolution $σ_E/E$ is (5.8 $\pm$ 0.2)% at an energy of 511 keV. This was achieved using a combination of the scintillation and the ionization signals. A photomultiplier tube gain calibration technique, based on the electroluminescence signals occurring from isolated electrons, is presented and its advantages and limitations are discussed.

description: The flux-mortar mixed finite element method was recently developed for a general class of domain decomposition saddle point problems on non-matching grids. In this work we develop the method for Darcy flow using the multipoint flux approximation as the subdomain discretization. The subdomain problems involve solving positive definite cell-centered pressure systems. The normal flux on the subdomain interfaces is the mortar coupling variable, which plays the role of a Lagrange multiplier to impose weakly continuity of pressure. We present well-posedness and error analysis based on reformulating the method as a mixed finite element method with a quadrature rule. We develop a non-overlapping domain decomposition algorithm for the solution of the resulting algebraic system that reduces it to an interface problem for the flux-mortar, as well as an efficient interface preconditioner. A series of numerical experiments is presented illustrating the performance of the method on general grids, including applications to flow in complex porous media.

description: This paper revealed the development of the movement for urban design by local proprietors in Ginza, Tokyo from 1930’s to 1960’s. Ginza Street is known as one of the first modern style streets in Japan. This street has developed greatly by modern buildings and advanced urban design methods in modern times and after although it has also suffered serious damage twice by Great Kanto Earthquake (1923) and bombing in 1945. Therefore, buildings and urban space have seen repeated reconstruction and renewal until today. On the other hand, if we pay attention to local proprietors, we can understand that they have developed the movement for urban design of Ginza Street continuously and succeeded the awareness of the issues toward urban space. So this paper finds a new historical context of Ginza through the elucidation of development of their movement from viewpoints of how the awareness of the issues and the image of spaces have changed.

description: Living Heritage is characterized by ‘continuity’, in particular those historic places that are still a ‘living’ part of their community. In China, the mainstream of living heritage conservation is shifting from commodity-oriented renewal to culture-oriented and people-centred revival, which has obviously displayed in many planning practices. This paper centres on the connotation of living heritage and explores its applications approaches through two conservation practices in Nanjing, China. In the first project, the author conceived a brand-new way of protecting and revealing historic streets, named ‘Reflection Alley’. It treats the street as an open museum, utilizing current semi-dismantled remains, providing a stage for dialogues between history and modernity, endowing the historic legacy with a sustainable future. In the second project, a ‘Five-stakeholder Platform’ is set up to support the progressive revitalization of a historic district. Through in-depth community engagement, the design team have developed a three-phase planning guide helping locals to protect and repair their residences thus stimulating the vitality of community life. The paper provides solutions for the implementation of culture-oriented and people-centred revival through the interaction between tangible and intangible parts and the connections to community.

Publisher: name: University of Illinois at Chicago
Year: 2023

description: Polarized light microscopy, stereo microscopy, microchemical and spot tests were used to examine, analyze, and document materials commonly used in low explosives and often associated with improvised explosive devices. Examination, analysis, and documentation was carried out on readily available chemical oxidizers and fuel sources in three conditions; unreacted, partially burned and fully burned. Materials included in this study include oxidizers such as potassium nitrate, urea and urea nitrate as well as fuels such as woodmeal, sugar, starch, dextrin, sulfur, ground spices, red phosphorus, and aluminum powders. The optical properties were recorded in each condition and most importantly, an array of photomicrographs were taken using various microscopical techniques; plane polarized light, crossed polars, partially uncrossed polars, reflected light and fluorescence when applicable. Optical properties as well as morphological features which assist in the identification of materials used in this study are also documented. Additionally, several microcrystal and spot tests were evaluated and found to be applicable for the identification of materials in their intact and partially burned states, specifically tests for aluminum and urea. Photomicrographs will serve to expand the limited photographic resources currently available to the trace evidence examiner and the additional use of spot and microcrystal tests will also aid the examiner in the identification of materials in various conditions which may result after an explosion or blast has occurred.

description: Magnetic-field-resilient superconducting coplanar waveguide (SCPW) resonators are essential for developing integrated quantum circuits of various qubits and quantum memory devices. Molybdenum-Rhenium (MoRe), which is a disordered superconducting alloy forming a highly transparent contact to the graphene and carbon nanotubes (CNTs), would be a promising platform for realizing the field-resilient SCPW resonators combined with graphene- and CNT-based nano-hybrid qubits. We fabricated MoRe SCPW resonators and investigated their microwave transmission characteristics with varying temperature and external magnetic field. Our observations show that the thickness of MoRe film is a critical parameter determining the lower critical field, kinetic inductance, and characteristic impedance of the SCPW resonator, resulting in drastic changes in the quality factor and the resonance frequency. As a result, we obtained a maximum value of $Q_{i} > 10^{4}$ in parallel magnetic fields up to $B_{||} = 0.15$ T for the 27-nm-thick MoRe resonator. Our experimental results suggest that MoRe SCPW resonator would be useful for integrating nano-hybrid spin or gatemon qubits and for developing spin-ensemble quantum memory devices.

description: This article intends to explore the ideas and concepts that dominate the landmark versions of planning in a historical survey on the development of urban planning for the construction of Guangzhou. From the Late 17th C. to the Mid-19th C. Xiguan in Guangzhou witnessed the booming of the Thirteen-hong characterized by gardens and buildings in Western architectural styles. These characteristics constituted the architectural features and urban spatial patterns on both sides of the Pearl River, and caused the moving westward of the ancient city center to the Thirteen-hong Business District. After The Second Opium War Western merchants began their planning and construction of Shameen with Western planning techniques, which, together with the model of the Thirteen-hong, led to the urban modernization of Guangzhou urban planning. During the years from 1911 to 1948, the urban planning and construction in Guangzhou underwent a sequence of processes from simplicity to complexity, and from part to whole. There was also a process from the simple imitation of Western ideas and concepts of urban planning in Dashatou Island to the renovation of Guangzhou urban planning marked with road and park construction, This process includes the dismantle of the city walls for road construction in 1912, the prelude of modern urban planning of Guangzhou in 1914, the planning for network and city-round road and park construction in 1918, the idea of “Traffic First” in 1921, the regional studies and planning in 1923, the concept of functional division in 1932, the idea of implementing urban function division in 1920s and 1930s, and the transference from the initial techniques and measures to land management in 1937. After that there was the adoption of the "zonal cluster layout" along the Pearl River in 1984, the idea of the Planning of Urban Agglomeration of the Pearl River Delta in 1995, and the continuation of the “four land usage modes” in 2003. The idea and concept of urban planning for Guangzhou, thus derived localized from the practice of Western urban planning in the Thirteen-hong and Shameen, later underwent the municipal planning of Dashatou, the idyllic residential districts. The innovated regional green space in 2006, followed by the livable urban and rural planning in 2016, and up to the lately ecological city in 2018, all bear the marks of the early ideas and concepts realized in the Thirteen-hong, Shameen, and Dashatou. Therefore, it can be further concluded that the urban planning of Guangzhou, developed from the initial function of landscape beautification to the regulation of regional green environment of the Pearl River Delta, underwent finally a full process of imitation, learning, transformation, and innovation, resulting in an idea of green, open, and shared urban construction.

description: We report calculations of the electronic structure, vibrational properties and transport for the p-type semiconductors, SrAg$Ch$F ($Ch$=S, Se and Te). We find soft phonons with low frequency optical branches intersecting the acoustic modes below 50 $cm^{-1}$, indicative of a material with low thermal conductivity. The bands at and near the valence band maxima are highly two dimensional, which leads to high thermopowers even at high carrier concentrations, which is a combination that suggests good thermoelectric performance. These materials may be regarded as bulk realizations of superlattice thermoelectrics.

Yet most spherical shell convective scaling laws use globally-averaged quantities that erase latitudinal differences in the physics. Here we quantify those latitudinal differences by analyzing spherical shell simulations in terms of their regionalized convective heat transfer properties. This is done by measuring local Nusselt numbers in two specific, latitudinally separate, portions of the shell, the polar and the equatorial regions, $Nu_p$ and $Nu_e$, respectively. In rotating spherical shells, convection first sets in outside the tangent cylinder such that equatorial heat transfer dominates at small and moderate supercriticalities. We show that the buoyancy forcing, parameterized by the Rayleigh number $Ra$, must exceed the critical equatorial forcing by a factor of $\approx 20$ to trigger polar convection within the tangent cylinder. Once triggered, $Nu_p$ increases with $Ra$ much faster than does $Nu_e$. The equatorial and polar heat fluxes then tend to become comparable at sufficiently high $Ra$. Comparisons between the polar convection data and Cartesian numerical simulations reveal quantitative agreement between the two geometries in terms of heat transfer and averaged bulk temperature gradient. This agreement indicates that spherical shell rotating convection dynamics are accessible both through spherical simulations and via reduced investigatory pathways, be they theoretical, numerical or experimental.

description: Within 2,000 years, Vietnam was ruled by China for more than 1,000 years, was colonized by France for almost 100 years, and was divided into pro-American and pro-Soviet Union camps for more than 20 years during the world's cold war. It can be stated that Vietnam’s political, social, cultural and other aspects contain deep foreign trails, the same as urban planning. The article reviews some foreign thoughts, their practices and their influences that appeared in the history of Vietnam. With limited historical data and imperfect research foundations, these papers aim to reconstruct a clue about planning characters and planning events. Based on the source of thoughts, this article summarizes the perceived historical information and divides it into four parts: China, France, the Soviet Union and the United States, presenting in chapters while focusing on an important feature of urban planning in Vietnam, which is the superposition of multiple dimensions of urban and rural concepts, construction techniques and concept technology of different cultures in the same physical space dimension. In the conclusion, the article will analyze this feature, explains how it has been formed and what kind of influence and effect it has had on urban planning since 1986 Doi Moi.

description: The observational effects of the 'Infrared Catastrophe' are discussed in view of the very late observations of the Type Ia SN 2011fe. Our model spectra at 1000d take non-local radiative transfer into account, and find that this has a crucial impact on the spectral formation. Although rapid cooling of the ejecta to a few 100 K occurs also in these models, the late-time optical/NIR flux is brighter by 1-2 magnitudes due to redistribution of UV emissivity, resulting from non-thermal excitation and ionization. This effect brings models into better agreement with late-time observations of SN 2011fe and other Type Ia supernovae, and offers a solution to the long standing discrepancy between models and observations. The models show that spectral formation shifts from Fe II and Fe III at 300d to Fe I at 1000d, which explains the apparent wavelength shifts seen in SN2011fe. We discuss effects of time dependence and energy input from 57Co, finding both to be important at 1000d.

Reception of Città Ideale

description: The concept of the Ideal City, as developed in Italy during the 15th and 16th centuries, has produced a significant number of treatises with texts and drawings, which, largely speaking, are theoretical rather than applied. Although new Renaissance towns were quite a rare phenomenon both in Italy and in other countries, a number of such towns were constructed in the Polish-Lithuanian Commonwealth. Two types of new towns were built according to their basic functions: the town-and-residence compounds were prestigious family seats combined with adjacent towns, while the “economic” towns were local trading centres. The fashionable ideas and forms of the Città Ideale were adopted by those towns’ founders and planners. Selected examples of Polish Renaissance towns are discussed in this paper. Apart from Zamosc (1578, designed by Bernardo Morando and often considered the most perfect Ideal City, and not only in Poland), other slightly less ideal though equally interesting townand- residence compounds are also described: Zolkiew (1584, now Zhovkva, Ukraine) and Stanislawow (1662, now Ivano-Frankivsk, Ukraine). Three of the “economic” towns are also presented here: Glowow (1570, now Glogow Malopolski), Rawicz (1638) and Frampol (founded as late as c. 1717, although still of a purely Renaissance form).

description: Concussions are a problem in competitive sports with growing concern over the acute and long-term consequences of repetitive head trauma. Participation in sport increases risk of concussion, particularly contact sports including rugby, hockey and football (Harmon et al., 2013). In rugby league, there are between 8.0-17.5 concussions/1000 player hours, representing roughly 10-15% of all injuries in the sport (Gardner et al., 2015). Shoulder, head, hip and knee are reported to be the most common regions that impact the head and are responsible for the greatest number of concussive injuries in rugby (Cusimano et al., 2013; Fuller et al., 2010; Gardner et al., 2014; Toth, Mcneil, & Feasby, 2005). In each of the common injury events reported in elite men’s rugby, there are unique combinations of impact conditions which include effective mass, compliance, velocity and location of impact. The head-to-head event represents a low mass, low compliance event, whereby the hip and shoulder-to-head collisions represents high mass, high compliance events. Scientists have conducted research in an effort to describe incidence and mechanisms of concussive injury in rugby, however, little is known about the biomechanics of head injury in the sport (Fréchède & Mcintosh, 2009; Fréchède & McIntosh, 2007; McIntosh et al., 2000). The purpose of this thesis is to characterize dynamic response and brain tissue deformation for (1) hip-to-head, (2) shoulder-to-head, (3) knee-to-head, and (4) head-to-head concussion events in men’s rugby. Twenty-nine (29) impact videos of diagnosed concussive injuries associated with the four common injury events were reconstructed in the Neurotrauma Impact Science Lab. Head-to-head impacts were reconstructed in this study using a pendulum system, while hip, shoulder and knee to head impacts were reconstructed using the pneumatic linear impactor. Results of this study demonstrate that the common injury events resulting in concussion in elite men’s rugby have different dynamic response characteristics. Head-to-head events produced significantly greater peak linear and peak rotational acceleration, however no significant differences in maximum principal strain between the injury events. Results of this study can be useful in reducing rates and severity of concussive injury in rugby.

description: AT 2019avd is a nuclear transient detected from infrared to soft X-rays, though its nature is yet unclear. The source has shown two consecutive flaring episodes in the optical and the infrared bands and its second flare was covered by X-ray monitoring programs. During this flare, the UVOT/Swift photometries revealed two plateaus: one observed after the peak and the other one appeared ~240 days later. Meanwhile, our NICER and XRT/Swift campaigns show two declines in the X-ray emission, one during the first optical plateau and one 70-90 days after the optical/UV decline. The evidence suggests that the optical/UV could not have been primarily originated from X-ray reprocessing. Furthermore, we detected a timelag of ~16-34 days between the optical and UV emission, which indicates the optical likely comes from UV reprocessing by a gas at a distance of 0.01-0.03 pc. We also report the first VLA and VLBA detection of this source at different frequencies and different stages of the second flare. The information obtained in the radio band - namely a steep and a late-time inverted radio spectrum, a high brightness temperature and a radio-loud state at late times - together with the multiwavelength properties of AT 2019avd suggests the launching and evolution of outflows such as disc winds or jets. In conclusion, we propose that after the ignition of black hole activity in the first flare, a super-Eddington flaring accretion disc formed and settled to a sub-Eddington state by the end of the second flare, associated with a compact radio outflow.

description: This paper analyses the role of McDonald’s in Hong Kong as a consumption-oriented place where the production of social space happens under the constraints of the market’s spectacle and speculations. McDonald’s in Hong Kong have evolved from the original aesthetics of the company, with a colorful postmodern cafeteria look, to the latest concept “Next” with a bold design, neat materiality, touch screens and open layout. Throughout this process, its restaurant design and polices have evolved by appropriating the rhythms of the city and its citizens. Whereas Hong Kong’s city escape is commonly perceived as the product of top down strategies carried out by “coalitions” between public institutions and private corporations, McDonald’s offers a case study of informal activities influencing the way a global enterprise develops. Its new “Next” concept might be seen as an attempt to anticipate informality. Two opposing ideas underlie this “open look”: the aim to homogenize customers through the sanitation of the space, versus the provision of neutral spaces to allow for the occurrence of heterogeneity. The presence of the screen as an intermediary between the restaurant and its customers empowers a dichotomy between an impersonal fast food service and current paradigms that aim to prioritize people and food.
