description: Since the recognition of the hypercoagulable state in COVID-19 patients, several interim guidance documents have recommended the use of pharmacologic thromboprophylaxis in hospitalized patients with COVID-19. Most of these guidelines recommend the use of unfractionated heparin (UFH) or low molecular weight heparin (LMWH), though the consensus is yet to be reached in the recommendations of standard(low), intermediate or therapeutic (full) dose anticoagulation. We seek to systematically review the available evidence to help guide clinicians weighing up decisions regarding the anticoagulation approach for COVID-19 patients admitted to intensive care units.

description: Motivated by damage due to heating in sensor operation, we consider the throughput optimal offline data scheduling problem in an energy harvesting transmitter such that the resulting temperature increase remains below a critical level. We model the temperature dynamics of the transmitter as a linear system and determine the optimal transmit power policy under such temperature constraints as well as energy harvesting constraints over an AWGN channel. We first derive the structural properties of the solution for the general case with multiple energy arrivals. We show that the optimal power policy is piecewise monotone decreasing with possible jumps at the energy harvesting instants. We derive analytical expressions for the optimal solution in the single energy arrival case. We show that, in the single energy arrival case, the optimal power is monotone decreasing, the resulting temperature is monotone increasing, and both remain constant after the temperature hits the critical level. We then generalize the solution for the multiple energy arrival case.

We include the nucleon resonances with pin $1/2$ in the $s$ channel. The coupling constants have been etermined by assuming that the decay process $N^* \to (ππ)_{I=0,J=0}N$ can be regarded as $N^* \to f_0(500) N$. We discuss the numerical results for the total cross sections and possible extension of the present work.

description: We show that if a modular cuspidal eigenform $f$ of weight $2k$ is $2$-adically close to an elliptic curve $E/\mathbb{Q}$, which has a cyclic rational $4$-isogeny, then $n$-th Fourier coefficient of $f$ is non-zero in the short interval $(X, X + cX^{\frac{1}{4}})$ for all $X \gg 0$ and for some $c > 0$. We use this fact to produce non-CM cuspidal eigenforms $f$ of level $N>1$ and weight $k > 2$ such that $i_f(n) \ll n^{\frac{1}{4}}$ for all $n \gg 0$.

This randomized trial aimes at estimating among people living with HIV, the extent that providing feedback on health outcomes, compared to no feedback, affects the number and specificity of self-management goals. Participants in a Canadian HIV brain health cohort study will be randomized to receive or not “My Personal Brain Health Dashboard” prior to a goal setting exercise. Self- defined goals in free text will be collected through an online platform. Text mining will be used to quantify goal specificity based on word matches with a goal-setting lexicon.
Features associated with diet pill use in individuals with eating disorders

Year: 2006

description: The relation between diet pill use and eating disorder (ED) diagnostic subtype, purging and compensatory behaviors, tobacco and substance use, personality characteristics, and Axis I and Axis II disorders was investigated. The sample included 1315 participants with ED diagnoses and diet pill use data from the multisite, Price Foundation Genetics Studies. Results indicated that diet pill use was associated with increased weight control behaviors, novelty seeking, anxiety disorders, substance use disorders, and borderline personality disorder, and negatively associated with narcissistic personality disorder. Findings suggest that certain clinical and personality variables distinguish individuals with EDs who use diet pills from those who do not. In the ED population, vigilant screening for diet pill use is an imperative clinical objective.
Proteus mirabilis Utilizes a Contact Dependent Growth Inhibition System to Kill Competitor Species

Publisher: name: University of Illinois at Chicago

description: The microbial organisms that colonize the human body are more abundant than somatic cells and contain more genes than the human genome. An estimated 500–1000 species of bacteria exist in and on the human body. The composition of polymicrobial communities in locations such as the gut and the urinary tract is shaped by the host but also by cooperative and competitive interactions between species. The study of bacterial competition systems has received significant attention in recent years, as they represent promising narrow-spectrum tools to eliminate pathogenic species. However, only few interbacterial competition systems have been identified and many more remain to be discovered. We observed competition between two common gut commensal bacteria that could be due to the action of a new competition system. In the gut of neonatal mice, commensal Proteus mirabilis eliminated Escherichia coli. We replicated this phenotype in vitro and demonstrated that mouse P. mirabilis killed Gram negative bacteria. However, P. mirabilis could not kill Gram positive or eukaryotic target cells. Killing required direct contact between P. mirabilis and its target cells, but killing was independent of the Type 6 Secretion System (T6SS), which is the only contact-dependent killing system described for P. mirabilis. The killing system was regulated by components secreted into the supernatant. Target cells lost nucleoid integrity and reduced transcription and metabolic activity. Through genomic comparison, we discovered that P. mirabilis encodes for a Contact Dependent growth Inhibition (CDI) system. The CDI system is a two-partner secretion system wherein the CdiB protein exports and displays its partner CdiA, the effector toxic protein. CDI producer cells are protected by an immunity protein, CdiI. A P. mirabilis mutant in the cdiA toxin did not kill target cells. Additionally, heterologous expression of the immunity gene rescued viability of E. coli in co-culture with P. mirabilis. Based on sequence homology, we grouped Proteus CDI systems into three classes. To our knowledge, this is the first report of CDI-mediated interbacterial competition for P. mirabilis. This system could be used by P. mirabilis to eliminate competitor species during a polymicrobial infection.
Reducing Nursing Stigma of Patients Diagnosed with Psychiatric Illnesses on a Medical-Surgical Inpatient Unit

Year: 2017

description: Background: Individuals diagnosed with psychiatric illnesses are frequently hospitalized in non-psychiatric settings for either medical illnesses, surgery, and/or for symptom exacerbation. The nurses who care for those patients often do not have adequate education and training to provide clinically competent and culturally sensitive psychiatric-mental health nursing care. Purpose: The purpose of this project was to: (a) increase medical-surgical nurses’ and nursing assistant’s understanding of psychiatric illnesses, (b) enhance compassionate care, and (c). decrease the negative attitudes associated with stigma related to patients who have comorbid physical/psychiatric illnesses in the inpatient medical-surgical setting. Methods: This Quality Improvement Project followed a step-by-step process (PDSA) to identify the learning needs of nursing staff and the potential for negative attitudes and stigmatizing behaviors on an inpatient medical-surgical unit in a community hospital. The administration of a learning needs assessment initiated the QI process and the 4-week interactive educational-training program that incorporated evidence-based stigma reduction modalities and education tailored to the setting’s patient population. The nursing staff’s attitudes were measured as a group pre- and post-program completion using the Mental Illness: Clinicians’ Attitudes, Version Four Scale (MICA v4). A post-survey was administered to assess the nursing staff’s perception of compassion and understanding after program completion. Results: Overall, the QI project was successfully implemented and focused on patient-centered nursing care. The post-program evaluation indicated that the project promoted nursing staff to have a better understanding of psychiatric illnesses, while also enhancing their ability to provide compassionate nursing care. The MICA v4 scores (using aggregate data) decreased from 38.8 to 33.8, indicating an improved attitude (and decreased stigma) towards patients with psychiatric illnesses. An unpaired t-test resulted in a p-level of 0.00067 indicating a potential correlational relationship between the education/training program and attitudinal change. Conclusion/Implications: The project was able to meet and exceed its three main purposes, with the potential of replicating this program hospital-wide. Limitations included low attendance, use of a low strength statistical correlational test, and use of a stigma tool that requires further research. Future programs should track individual stigma scores, measure behavioral outcomes, and use a stigma survey that has been widely used.

description: Onychophorans, or velvet worms, are poorly known and rare animals. Here we report the discovery of a new species that is also the largest onychophoran found so far, a 22cm long female from the Caribbean coastal forest of Costa Rica. Specimens were examined with Scanning Electron Microscopy; Peripatus solorzanoi sp. nov., is diagnosed as follows: primary papillae convex and conical with rounded bases, with more than 18 scale ranks. Apical section large, spherical, with a basal diameter of at least 20 ranks. Apical piece with 6-7 scale ranks. Outer blade 1 principal tooth, 1 accessory tooth, 1 vestigial accessory tooth (formula: 1/1/1); inner blade 1 principal tooth, 1 accessory tooth, 1 rudimentary accessory tooth, 9 to 10 denticles (formula: 1/1/1/9-10). Accessory tooth blunt in both blades. Four pads in the fourth and fifth oncopods; 4th. pad arched. The previously unknown mechanism by which onychophorans weave their adhesive is simple: muscular action produces a swinging movement of the adhesive-spelling organs; as a result, the streams cross in mid air, weaving the net. Like all onychophorans, P. solorzanoi is a rare species: active protection of the habitat of the largest onychophoran ever described, is considered urgent.

description: Superconductivity in two-dimensional compounds is widely concerned, not only due to its application in constructing nano-superconducting devices, but also for the general scientific interests. Very recently, borophene (two-dimensional boron sheet) has been successfully grown on the Ag(111) surface, through direct evaporation of a pure boron source. The experiment unveiled two types of borophene structures, namely $β_{12}$ and $χ_3$. Herein, we employed density-functional first-principles calculations to investigate the electron-phonon coupling and superconductivity in both structures of borophene. The band structures of $β_{12}$ and $χ_3$ borophenes exhibit inherent metallicity. We found electron-phonon coupling constants in the two compounds are larger than that in MgB$_2$. The superconducting transition temperatures were determined to be 18.7 K and 24.7 K through McMillian-Allen-Dynes formula. These temperatures are much higher than theoretically predicted 8.1 K and experimentally observed 7.4 K superconductivity in graphene. Our findings will enrich the nano-superconducting device applications and boron-related material science.

description: In the Netherlands awareness regarding the Urban Heat Island (UHI) was raised relatively recently. Because of this recent understanding, there is a lack of consistent urban micro-meteorological measurements to allow a conventional UHI assessment of Dutch cities during heat waves. This paper argues that it is possible to retrieve relevant UHI information – including adaptation guidelines – from satellite imagery. The paper comprises three parts. The first part consists of a study of suited indicators to identify urban heat islands from which a method is presented based on ground heat flux mapping. The second part proposes heat mitigation strategies and identifies the areas where these strategies could be applied within the hotspots identified in the cities of The Hague, Delft, Leiden, Gouda, Utrecht and Den Bosch. The third part estimates the reduction of urban heat generated by the increase of roof albedo in the hotspots of the six cities. The six cities hotspots are located within the boundaries of the 17th century city centres. In order to avoid interference with cultural values of these historical environments most likely UHI mitigation measures regard improving the thermal behaviour of the city roofs. For instance, applying white coatings on bitumen flat roofs (or replacing them by white single-ply membranes) and replacing sloped roof clay tiles by coloured tiles with cool pigments can reduce the urban heat hotspots by approximately 1.5°C. Remote sensing provides high level information that provide urban planners and policy makers with overall design guidelines for the reduction of urban heat.

description: The world is increasingly concerned with sustainability issues. Climate change is not the least of these concerns. The complexity of these issues is such that data and information management form an important means of making the right decisions. Nowadays, however, the sheer quantity of data is overwhelming; large quantities of data demand means of representation that are comprehensible and effective. The above dilemma poses questions as to how one incorporates unknown climatologic parameters, such as urban heat, in future urban planning processes, and how one ensures the proposals are specific enough to actually adapt cities to climate change and flexible enough to ensure the proposed measures are combinable and compatible with other urban planning priorities. Conventional urban planning processes and mapping strategies are not adapted to this new environmental, technological and social context. In order come up with more appropriate urban planning strategies, in its first section this paper analyses the role of the urban planner, reviews the wide variety of parameters that are starting to be integrated into the urban planners practice, and considers the parameters (mainly land surface temperature, albedo, vegetation and imperviousness) and tools needed for the assessment of the UHI (satellite imagery and GIS). The second part of the study analyses the potential of four catalysing mapping categories to integrate urban heat into spatial planning processes: drift, layering, game-board, and rhizome.

Regionalist principles to reduce the urban heat island effect

Year: 2017

description: Scientists, climatologists, and urban planners have started to recognize the importance of nature at two very different scales: the global (metabolic) and the local (liveability) scales. The regional scale is the one at which these macro and micro approaches overlap. Future predictions foresee an increase of more than 2450 million urban inhabitants by 2050, thus new balanced urban visions need to be developed in order to guarantee the sustainability of urban areas. The Urban Heat Island (UHI) effect is a climate phenomenon resulting from unbalanced urban design arrangements. This paper analyses several design principles proposed by the 1920's regionalists from the UHI perspective. The preservation of the regional geographical landmarks, the implementation of urban containment policies (limiting city sizes), the increase of greenery and the development of green multifunctional blocks would help reduce the UHI in future urban developments.

description: Although there are many scientific peer-reviewed journal articles studying the Urban Heat Island effect in depth for different case study cities around the world from a climatological perspective, there seems to be a gap between the sophisticated available technologies (remote sensing), and the local UHI policies for the vast majority of medium-size to large cities. Urban planners punctually use images processed by remote sensing, but our discipline has not appropriated such a powerful tool yet. The objective of this research is to explore the potential of the use of remote sensing technology for urban planners to be able to analyse the thermal behaviour of cities, in order to generate action plans for thermal master planning at the scales of the region and the city.

First passage time distribution in heterogeneity controlled kinetics: going beyond the mean first passage time

description: The first passage is a generic concept for quantifying when a random quantity such as the position of a diffusing molecule or the value of a stock crosses a preset threshold (target) for the first time. The last decade saw an enlightening series of new results focusing mostly on the so-called mean and global first passage time (MFPT and GFPT, respectively) of such processes. Here we push the understanding of first passage processes a step further. For a simple heterogeneous system we derive rigorously the complete distribution of first passage times (FPTs). Our results demonstrate that the typical FPT significantly differs from the MFPT, which corresponds to the long time behaviour of the FPT distribution. Conversely, the short time behaviour is shown to correspond to trajectories connecting directly from the initial value to the target. Remarkably, we reveal a previously overlooked third characteristic time scale of the first passage dynamics mirroring brief excursion away from the target.

description: We report on the discovery of an ultrasoft X-ray transient source, 3XMM J152130.7+074916. It was serendipitously detected in an XMM-Newton observation on 2000 August 23, and its location is consistent with the center of the galaxy SDSS J152130.72+074916.5 (z=0.17901 and d_L=866 Mpc). The high-quality X-ray spectrum can be fitted with a thermal disk with an apparent inner disk temperature of 0.17 keV and a rest-frame 0.24-11.8 keV unabsorbed luminosity of ~5e43 erg/s, subject to a fast-moving warm absorber. Short-term variability was also clearly observed, with the spectrum being softer at lower flux. The source was covered but not detected in a Chandra observation on 2000 April 3, a Swift observation on 2005 September 10, and a second XMM-Newton observation on 2014 January 19, implying a large variability (>260) of the X-ray flux. The optical spectrum of the candidate host galaxy, taken ~11 yrs after the XMM-Newton detection, shows no sign of nuclear activity. This, combined with its transient and ultrasoft properties, leads us to explain the source as tidal disruption of a star by the supermassive black hole in the galactic center. We attribute the fast-moving warm absorber detected in the first XMM-Newton observation to the super-Eddington outflow associated with the event and the short-term variability to a disk instability that caused fast change of the inner disk radius at a constant mass accretion rate.

description: The time and place of the postwar struggle of the Ukrainian Insurgent Army (UPA) against the Soviet regime in West Ukraine contradicted two foundational myths of late Soviet society: 1) the myth of the Great Patriotic War, and 2) the myth of the Friendship of the Peoples. This thesis examines how Soviet-Russian mass media dealt with these contradictions in the decades leading up to perestroika. The Soviet state attempted to excise the UPA's postwar activities from collective memory through omission until the early 1980s, when it launched a propaganda campaign to expose and demonize the UPA. The new political circumstances of the Second Cold War account for the timing of this campaign, but the well worn language and arguments it employed reflected the stagnation of the Party's postwar ideology, which posited the unity and incorruptibility of the new historical community of the Soviet people, and accordingly denationalized the UPA's treachery.

description: Random walks are a fundamental model in applied mathematics and are a common example of a Markov chain. The limiting stationary distribution of the Markov chain represents the fraction of the time spent in each state during the stochastic process. A standard way to compute this distribution for a random walk on a finite set of states is to compute the Perron vector of the associated transition matrix. There are algebraic analogues of this Perron vector in terms of transition probability tensors of higher-order Markov chains. These vectors are nonnegative, have dimension equal to the dimension of the state space, and sum to one and are derived by making an algebraic substitution in the equation for the joint-stationary distribution of a higher-order Markov chains. Here, we present the spacey random walk, a non-Markovian stochastic process whose stationary distribution is given by the tensor eigenvector. The process itself is a vertex-reinforced random walk, and its discrete dynamics are related to a continuous dynamical system. We analyze the convergence properties of these dynamics and discuss numerical methods for computing the stationary distribution. Finally, we provide several applications of the spacey random walk model in population genetics, ranking, and clustering data, and we use the process to analyze taxi trajectory data in New York. This example shows definite non-Markovian structure.

description: Spectroscopy of hydrogen can be used for a search into physics beyond the Standard Model. Differences between the absorption spectra of H$_2$ as observed at high redshift and those measured in the laboratory can be interpreted in terms of possible variations of the proton-electron mass ratio. Investigation of some ten of such absorbers in the redshift range $z= 2.0-4.2$ yields a constraint of $|Δμ/μ|< 5 \times 10^{-6}$ at 3$σ$. Observation of H$_2$ from the photospheres of white dwarf stars inside our Galaxy delivers a constraint of similar magnitude on a dependence of $μ$ on a gravitational potential $10^4$ times as strong as on the Earth's surface. Laser-based precision measurements of dissociation energies, vibrational splittings and rotational level energies in H$_2$ molecules and their deuterated isotopomers HD and D$_2$ produce values for the rovibrational binding energies fully consistent with quantum ab initio calculations including relativistic and quantum electrodynamical (QED) effects. Similarly, precision measurements of high-overtone vibrational transitions of HD$^+$ ions, captured in ion traps and sympathetically cooled to mK temperatures, also result in transition frequencies fully consistent with calculations including QED corrections. Precision measurements of inter-Rydberg transitions in H$_2$ can be extrapolated to yield accurate values for level splittings in the H$_2^+$-ion. These comprehensive results of laboratory precision measurements on neutral and ionic hydrogen molecules can be interpreted to set bounds on the existence of possible fifth forces and of higher dimensions, phenomena describing physics beyond the Standard Model.

description: Microswimmers or active elements, such as bacteria and active filaments, have an elongated shape, which determines their individual and collective dynamics. There is still a need to identify what role long-range hydrodynamic interactions play in their fascinating dynamic structure formation. We construct rods of different aspect ratios using several spherical squirmer model swimmers. With the help of the mesoscale simulation method of multi-particle collision dynamics we analyze the flow fields of these squirmer rods both in a bulk fluid and in Hele-Shaw geometries of different slab widths. Based on the hydrodynamic multipole expansion either for bulk or confinement between two parallel plates, we categorize the different multipole contributions of neutral as well as pusher-type squirmer rods. We demonstrate how confinement alters the radial decay of the flow fields for a given force or source multipole moment compared to the bulk fluid.

description: Atmospheric fine particulate matters (PM2.5) adversely affects air quality and human health. Isoprene is the most abundant non-methane volatile organic compound primarily emitted from biogenic sources to Earth’s atmosphere. Atmospheric oxidation of isoprene yields large quantities of gaseous isoprene epoxydiol (IEPOX) by hydroxyl radicals under low-nitric oxide conditions. IEPOX subsequently undergoes acid-catalyzed multiphase chemistry with natural or anthropogenic sulfate aerosol, producing substantial amounts of water-soluble IEPOX-derived secondary organic aerosol (SOA) in PM2.5. The hydrophilic interaction liquid chromatography interfaced to electrospray ionization-high-resolution quadrupole time-of-flight mass spectrometry (HILIC/ESI-HR-QTOFMS) method presented here overcomes limitations of commonly utilized analytical techniques, making it possible to identify and quantify water-soluble SOA constituents by a single analytical method. Atmospheric chemistry model predictions of the water-soluble IEPOX-derived SOA constituents (e.g., 2-methyltetrols and methyltetrol sulfates) in PM2.5 can now be assessed with greater accuracy and confidence.

Typically, the coarse-grained fluid particles are described by the equation of state of an ideal gas, and the fluid is rather compressible. This is in contrast to conventional fluids, which are incompressible for velocities much below the speed of sound, and can cause inhomogeneities in density. We propose an algorithm for MPCD with a modified collision rule that results in a non-ideal equation of state and a significantly decreased compressibility. It allows simulations at less computational costs compared to conventional MPCD algorithms. We derive analytic expressions for the equation of state and the corresponding compressibility as well as shear viscosity. They show overall very good agreement with simulations, where we determine the pressure by simulating a quiet bulk fluid and the shear viscosity by simulating a linear shear flow and a Poiseuille flow.

description: Simulations of flow fields around microscopic objects typically require methods that both solve the Navier–Stokes equations and also include thermal fluctuations. One such method popular in the field of soft-matter physics is the particle-based simulation method of multi-particle collision dynamics (MPCD). However, in contrast to the typically incompressible real fluid, the fluid of the traditional MPCD methods obeys the ideal-gas equation of state. This can be problematic because most fluid properties strongly depend on the fluid density. In a recent article, we proposed an extended MPCD algorithm and derived its non-ideal equation of state and an expression for the viscosity. In the present work, we demonstrate its accuracy and efficiency for the simulations of the flow fields of single squirmers and of the collective dynamics of squirmer rods. We use two exemplary squirmer-rod systems for which we compare the outcome of the extended MPCD method to the well-established MPCD version with an Andersen thermostat. First, we explicitly demonstrate the reduced compressibility of the MPCD fluid in a cluster of squirmer rods. Second, for shorter rods, we show the interesting result that in simulations with the extended MPCD method, dynamic swarms are more pronounced and have a higher polar order. Finally, we present a thorough study of the state diagram of squirmer rods moving in the center plane of a Hele-Shaw geometry. From a small to large aspect ratio and density, we observe a disordered state, dynamic swarms, a single swarm, and a jammed cluster, which we characterize accordingly.

description: We give effective lower bounds for $L(1,χ)$ via Eisenstein series on $Γ_0(q) \backslash \mathbb{H}$. The proof uses the Maass-Selberg relation for truncated Eisenstein series and sieve theory in the form of the Brun-Titchmarsh inequality. The method follows closely the work of Sarnak in using Eisenstein series to find effective lower bounds for $ζ(1+it)$.

description: The self-energy embedding theory (SEET), in which the active space self-energy is embedded in the self-energy obtained from a perturbative method treating the non-local correlation effects, was recently developed in our group. In SEET the double counting problem does not appear and the accuracy can be improved either by increasing the perturbation order or by enlarging the active space. This method was first calibrated for the 2D Hubbard lattice showing promising results. In this paper, we report an extension of SEET to quantum chemical ab initio Hamiltonians for applications to molecular systems. The self-consistent second-order Green's function (GF2) method is used to describe the non-local correlations, while the full configuration interaction (FCI) method is carried out to capture strong correlation within the active space. Using few proof-of-concept examples, we show that SEET yields results of comparable quality to $n-$electron valence state second-order perturbation theory (NEVPT2) with the same active space, and furthermore, the full active space can be split into smaller active spaces without further implementation. Moreover, SEET avoids intruder states and does not require any high-order reduced density matrices. These advantages show that SEET is a promising method to describe physical and chemical properties of challenging molecules requiring large active spaces.
Unquenched quark-model calculation of excited $ρ$ resonances and P-wave $ππ$ phase shifts

description: The $ρ(770)$ vector resonance, its radial recurrences, and the corresponding P-wave $ππ$ phase shifts are investigated in an unquenched quark model with all classes of relevant decay channels included, viz. pseudoscalar-pseudoscalar, vector-pseudoscalar, vector-vector, vector-scalar, axialvector-pseudoscalar, and axialvector-vector, totalling 26 channels. Two of the few model parameters are fixed at previously used values, whereas the other three are adjusted to the $ρ(770)$ resonance and the lower P-wave $ππ$ phases. Preliminary results indicate the model's capacity to reproduce these phases as well as the $ρ$ mass and width. However, at higher energies the phase shifts tend to rise too sharply. A possible remedy is an extension of the model so as to handle resonances in the final states for most of the included decay channels. Work in progress.

description: We report measurements performed on a polycrystalline sample of the pyrochlore compound Nd2Sn2O7. It undergoes a second order magnetic phase transition at Tc ~ 0.91 K to a noncoplanar all-in-all-out magnetic structure of the Nd3+ magnetic moments. The thermal behavior of the low temperature specific heat fingerprints excitations with linear dispersion in a three-dimensional lattice. The temperature independent spin-lattice relaxation rate measured below Tc and the anomalously slow paramagnetic spin dynamics detected up to ~ 30 Tc are suggested to be due to magnetic short-range correlations in unidimensional spin clusters, i.e., spin loops. The observation of a spontaneous field in muon spin relaxation measurements is associated with the absence of a divergence-free field for the ground state of an all-in-all-out pyrochlore magnet as predicted recently.

description: Starting from the representation of the $(n-1)+n-$dimensional Lorentz pseudo-sphere on the projective space $\mathbb{P}\mathbb{R}^{n,n}$, we propose a method to derive a class of solutions underlying to a Dirac-Kähler type equation on the lattice. We make use of the Cayley transform $φ({\bf w})=\dfrac{1+{\bf w}}{1-{\bf w}}$ to show that the resulting group representation arise from the same mathematical framework as the conformal group representation in terms of the {\it general linear group} $GL\left(2,Γ(n-1,n-1)\cup\{ 0\}\right)$. That allows us to describe such class of solutions as a commutative $n-$ary product, involving the quasi-monomials $φ\left({\bf z}_j\right)^{-\frac{x_j}{h}}$ ($x_j \in h\mathbb{Z}$) with membership in the paravector space $\mathbb{R}\oplus \mathbb{R}{\bf e}_j{\bf e}_{n+j}$.

Developing a Framework for Qualitative Evaluation of Urban Interventions in Iranian Historical Cores

description: Iranian historic city cores are important parts of modern cities because of their valuable monuments and morphology but are also significant because of their population density, location and the major governmental functions they house. Since 1920, modernisation policies and urban development trends in Iran have justified spatial transformation and redevelopment and the demolition and destruction of traditional urban fabrics as a way to provide contemporary requirements and hygiene improvements for the residents. As the UNESCO recommendation on the Historic Urban Landscape argues, historic urban cores can only sustain their role in the daily life of the city by getting prepared for and participating in this transformation process. Disagreement over the value of historic urban cores on the one hand and inevitable modification of urban areas in a developing country like Iran on the other, creates a problematic condition for the preservation of the historic environment. The Valletta Principles for the Safeguarding and Management of Historic Cities, Towns and Urban Areas states that historic towns and urban areas require an integrated approach including their “protection, conservation, enhancement and management as well as their coherent development and their harmonious adaptation to contemporary life”. In order to support the process of reaching a balance between these spatial targets in Iran, this research discusses the relation between urban transformation projects and their heritage context. In doing so it connects international literature on urban quality and traditional Iranian urban forms to contemporary Iranian urban design practice. To achieve this integration between urban heritage and spatial development, a framework of quality attributes has been developed to evaluate urban interventions in a heritage context. The three main pillars of this framework have been extracted from and inspired by international literature and guidelines. Place-making theories have proved to be especially helpful. An analysis of traditional urban forms in Iran and their main characteristics - especially for the urban type of the bazaar – has provided a list of specific and relevant parameters. The framework has been tested by evaluating two case studies in Shiraz that illustrate two different approaches to heritage intervention on an urban level. The outcome has led to modification of the framework and new research questions.

In doing so, we also connect these quantum privacy investigations with the theory of quasiorthogonal operator algebras through the use of tools from group theory and operator theory.
