description: We study the Borcherds superalgebra obtained by adding an odd (fermionic) null root to the set of simple roots of a simple finite-dimensional Lie algebra. We compare it to the Kac-Moody algebra obtained by replacing the odd null root by an ordinary simple root, and then adding more simple roots, such that each node that we add to the Dynkin diagram is connected to the previous one with a single line. This generalizes the situation in maximal supergravity, where the E(n) symmetry algebra can be extended to either a Borcherds superalgebra or to the Kac-Moody algebra E(11), and both extensions can be used to derive the spectrum of p-form potentials in the theory. We show that also in the general case, the Borcherds and Kac-Moody extensions lead to the same p-form spectrum of representations of the simple finite-dimensional Lie algebra.

description: We report the discovery, from WASP and CORALIE, of a transiting exoplanet in a 1.54-d orbit. The host star, WASP-36, is a magnitude V = 12.7, metal-poor G2 dwarf (Teff = 5959 \pm 134 K), with [Fe/H] = -0.26 \pm 0.10. We determine the planet to have mass and radius respectively 2.30 \pm 0.07 and 1.28 \pm 0.03 times that of Jupiter. We have eight partial or complete transit light curves, from four different observatories, which allows us to investigate the potential effects on the fitted system parameters of using only a single light curve. We find that the solutions obtained by analysing each of these light curves independently are consistent with our global fit to all the data, despite the apparent presence of correlated noise in at least two of the light curves.

Documenting Horror: The Use of Sound in Non-Fiction 9/11 Films

Year: 2011
Subjects: film studies; film sound; documentary; horror

description: While conventional 9/11 documentaries focus on the most known and  visible images of the attack, three films that work against this  tendency, 9/11 (2002), 11'09''01 - September 11 (2002) and Fahrenheit  9/11 (2004), avoid the television news coverage of the towers and  portray the attacks primarily through sound.

These films avoid or scantly interject the too familiar footage, working instead with the audio track’s ability to convey the horrors of the event.  By emphasizing sound, these films address a challenge familiar to documentary studies: how to appropriately represent a historical event whose tragic scale makes aesthetic representation questionable.

Oscillatory pairing amplitude and magnetic compressible-incompressible transitions in imbalanced fermionic superfluids in optical lattices of elongated tubes

description: We study two-species fermion gases with attractive interaction in two-dimensional optical lattices producing an array of elongated tube confinements. Focusing on the interplay of Cooper pairing, spin imbalance (or magnetization) and intertube tunneling, we find the pairing gap can exhibit oscillatory behavior both along and across the tubes, reminiscent of a Fulde-Ferrell-Larkin-Ovchinnikov (FFLO) phase. We obtain a Bose-Hubbard-like phase diagram that shows that the magnetization of the system undergoes an incompressible-compressible transition as a function of magnetic field and intertube tunneling strength. We find the parity of tube-filling imbalance in incompressible states is protected by that of the oscillatory pairing gap. Finally, we discuss signatures of this transition and thus (indirectly) of the FFLO pairing in cold atom experiments.

Blogging 9/11 and Memory Discourse

Subjects: memorialization practices, 9/11 blogs, trauma, war on terror

description: Marking ‘Time Zero’ in the history of the US and the world, the 9/11 catastrophe provoked an outburst of discourses that found an unprecedented sounding board in the blogosphere, flooded with fragmentary contributions from a global public that mostly witnessed the event mediated by TV coverage. Examining a decade bracketed by those traumatic attacks and Osama bin Laden’s death, we may ask ourselves in what relationship the continuous flow of comments, disclosures and news updates published on 9/11-related blogs stands to the making of the history of the event and what followed it, especially the emergence of the ‘war-on-terror’ rhetoric.
This article highlights a few of the salient discursive and linguistic patterns that recur in the 9/11 narratives that have multiplied online on several dedicated websites and investigates the evolution of 9/11 cultural memory practices, torn between the discourse of the unrepresentable and the imperative to remember. It claims that blogging 9/11, immediately after the attacks and over the years, well illustrates how the logic of memory and its interpretation of the past follow different criteria from history writing. It shows how memorialization practices, dictated by the fear of forgetting the vanishing present, contribute to that excess of memory that lies at the core of the instability and mutual competition of sources retrieved on the Internet and that might ultimately lead to a rethinking of what is the contribution of collective memory to historiography.

An “approximate knowledge”: event transmission in the post-9/11 informational culture
Creators: name: Picarelli, Enrica
Publisher: name: Università degli  Studi di Milano
Year: 2011
Subjects: informational culture; event; media event; affect; fear

description: The aim of the essay is to look back at 9/11 from the temporal perspective of 2011 and interpret it as a singularity, that is a moment of destabilization that hit the media sphere, accelerating an already existing shift in communication politics towards affective involvement. The dimension of pathic engagement that the televised images of 9/11 inspired, their becoming a source of collective emotional instability (i.e. a global “culture of fear”), has amplified preexisting modes of communication that relied on the energetic and mobilizing lure of audiovisual transmission. Rather than approaching 9/11 as a metaphysical occurrence, an absolute ‘event’ unencumbered by the territorializing pull of its own geopolitical genealogy, the essay engages with it as a phase boundary whose transformative impact can be sensed in the tactics of mobilization that inform contemporary communication practices.

description: We report on muon spin rotation studies of the noncentrosymmetric heavy fermion antiferromagnet CeRhSi$_3$. A drastic and monotonic suppression of the internal fields, at the lowest measured temperature, was observed upon an increase of external pressure. Our data suggest that the ordered moments are gradually quenched with increasing pressure, in a manner different from the pressure dependence of the Néel temperature. At $\unit{23.6}{kbar}$, the ordered magnetic moments are fully suppressed via a second-order phase transition, and $T_{\rm{N}}$ is zero. Thus, we directly observed the quantum critical point at $\unit{23.6}{kbar}$ hidden inside the superconducting phase of CeRhSi$_3$.

description: The singularity for the big bang state can be represented using the generalized anisotropic Friedmann equation, resulting in a system of differential equations in a central force field. We study the regularizability of this singularity as a function of a parameter, the equation of state, $w$. We prove that for $w >1$ it is regularizable only for $w$ satisfying relative prime number conditions, and for $w \leq 1$ it can always be regularized. This is done by using a McGehee transformation, usually applied in the three and four-body problems. This transformation blows up the singularity into an invariant manifold. The relationship of this result to other cosmological models is briefly discussed.

Strong X-ray variability in the quiescent state of the neutron star low-mass X-ray binary EXO 1745-248

description: The transient neutron star low-mass X-ray binary EXO 1745-248, located in the globular cluster Terzan 5, was detected during its quiescent state with Chandra in 2003. The source displayed a 0.5-10 keV X-ray luminosity of Lq ~ 1E33 (D/5.5kpc)^2 erg/s, which was completely dominated by hard non-thermal emission. This is at odds with other non-pulsating neutron stars that typically show detectable soft thermal emission at such quiescent luminosities. Here, we use three additional Chandra observations, performed in 2009 and 2011, to further study the quiescent properties of EXO 1745-248. We find that the powerlaw intensity varies considerably up to a factor of ~3 within hours and by about one order of magnitude between the different epochs. We discuss the implications of the observed change in quiescent flux for the interpretation of the hard powerlaw emission. Furthermore, we constrain the neutron star surface temperature as seen by a distant observer to kT_inf < 42 eV and the thermal bolometric luminosity to Lq,bol < 7E31 (D/5.5kpc)^2 erg/s. This confirms that EXO 1745-248 harbours a relatively cold neutron star and suggests that, for example, enhanced cooling mechanisms are operating in the stellar core, or that the binary on average resides in quiescence for hundreds of years.

description: SARS-CoV-2’s main protease (Mpro) interaction with ligands has been explored with a myriad of crystal structures, most of the monomers. Nonetheless, Mpro is known to be active as a dimer but the relevance of the dimerization in the ligand-induced conformational changes has not been fully elucidated. We systematically simulated different Mpro-ligand complexes aiming to study their conformational changes and interactions, through molecular dynamics (MD). We focused on covalently bound ligands (N1 and N3, ∼9 μs per system both monomers and dimers) and compared these trajectories against the apostructure. Our results suggest that the monomeric simulations led to an unrealistically flexible active site. In contrast, the Mpro dimer displayed a stable oxyanion-loop conformation along the trajectory. Also, ligand interactions with residues His41, Gly143, His163, Glu166 and Gln189 are postulated to impact the ligands' inhibitory activity significantly. In dimeric simulations, especially Gly143 and His163 have increased interaction frequencies. In conclusion, long-timescale MD is a more suitable tool for exploring in silico the activity of bioactive compounds that potentially inhibit the dimeric form of SARS-CoV-2 Mpro.

description: Focusing on Dale Maharidge and Michael Williamson’s reportage Homeland (2004), this essay explores the de-construction of the discursive and cultural strategies of the “state of exception” used to depict 9/11 events and the dialectics between domestic and international politics and economies. The analysis focuses in particular on four elements: the concept of “Ground Zero” and “Homeland” and their use as lexical and symbolic catalysts of nationalism; the forms and the erasure of dissent; the commodification of 9/11 and the Iraqi war; and the relation between the national rhetoric and the transnational economy in the last two decades.

description: Finding affordable ways of generating high-density ordered nanostructures that can be transferred to a substrate is a major challenge for industrial applications like memories or optical devices with high resolution features. In this work, we report on a novel technique to direct self-assembled structures of block copolymers by NanoImprint Lithography. Surface energy of a reusable mold and nanorheology are used to organize the copolymers in defect-free structures over tens of micrometers in size. Versatile and controlled in-plane orientations of about 25 nm half-period lamellar nanostructures are achieved and, in particular, include applications to circular tracks of magnetic reading heads.

Development of group 4 and 5 complexes with N,O chelating supporting ligands as catalysts for the alpha-alkylation of amines
Creators: name: Lauzon, Jean Michel
Publisher: name: University of British Columbia
Year: 2013

description: The use of stoichiometric, catalytic and theoretical methods in the development of an early transition metal catalyst for the α-alkylation of amines is described herein. The investigation is primarily focused on a series of mono(amidate) complexes of tantalum with varying steric and electronic properties. The amidate binding mode and catalytic activity of these complexes is significantly influenced by sterics. Corresponding bis(amidate) complexes are less active as catalysts for the α-alkylation of amines but offers a platform to study the hemi-lability of amidate ligands as well as tantalaziridine formation in these systems. A model 5-membered metallacycle is synthesized and characterized. Isotopic labeling studies with the most active mono(amidate) precatalyst reveal off-cycle reactions and suggest that tantalaziridine formation is rapid and reversible. Preliminary kinetic investigations implicate alkene insertion as the turnover limiting step, consistent with stoichiometric investigations. In addition, the use of radical probes in ligand backbones and an alkene substrate contradicts a one electron mechanism. Quantum chemical calculations are used to develop a theoretical model of the proposed catalytic cycle. The hemi-lability of amidate ligands is highlighted with the optimization of both κ¹(O) and κ²(N,O) minima and transition states. Here, protonolysis is calculated to be the turnover limiting step with small changes in geometry having a significant effect on the potential energy surface. The unlikelihood of a radical mechanism is supported by the computations of triplet species. A survey of established steric parameters has been completed for asymmetric amidate ligands to be used as a predictive tool for catalyst design. The calculated values can be related to the catalytic activity of mono(amidate) and axially chiral tantalum precatalysts. Diamide and diurea proligands featuring a neutral chalcogen atom tether are installed on zirconium and tantalum. The zirconium species form well-defined κ⁴(N,N,O,O) complexes with fluxional behaviour observed for the tantalum species in solution. No evidence of bonding is observed between the chalcogen donor and any metal centre. Fundamental differences in the redox potentials for ligands and complexes are investigated using cyclic voltammetry. The tantalum complexes are found to catalyze the α-alkylation of amines with the zirconium species being competent precatalysts for hydroamination.

description: The matrix Schroedinger equation with a selfadjoint matrix potential is considered on the half line with the general selfadjoint boundary condition at the origin. When the matrix potential is integrable, the high-energy asymptotics are established for the related Jost matrix, the inverse of the Jost matrix, and the scattering matrix. Under the additional assumption that the matrix potential has a first moment, Levinson's theorem is derived, relating the number of bound states to the change in the argument of the determinant of the scattering matrix.

Ripensare l’11 Settembre con Derrida: Tra evento e autoimmunità
Creators: name: Marchente, Arianna

Year: 2011
Subjects: major event; September 11th; event; auto-immunity

description: In a way, after the September 11th terrorist attack, we have all had the feeling that we witnessed a real major event. However, the notion of event itself is semantically problematic. The 10th anniversary of this date offers us the opportunity to interrogate ourselves with a new question: was this indeed an event? To what extent? This is the very question which opens Jacques Derrida’s interview, undertaken by Giovanna Borradori in New York a few days after the attack. Indeed the French philosopher Derrida provides us with deep insights into the notion of event, its underpinnings and semantic roots.
To a certain extent September 11th seems to be an event; indeed, how otherwise could it have given such a strong impression of being so? On the other hand however, it seems not to have been an event, in that it does not correspond to the Derridian definition of “event” as a surprise, as something totally unpredictable. September 11th - Derrida claims- was predictable and it’s not by chance that the US had created institutions such as the CIA or the NSA to defend themselves from this kind of threat. Nevertheless in understanding September 11th as something other than an event, we are forced to struggle with the question why was it that we first had the impression it was an event and why did it have such a strong impact on us?
We are therefore confronted with two new important questions. The first leads us to reflect on the role that the media played with respect to September 11th. What would September 11th have been –Derrida asks himself- without TV? The second question concerns the auto-immune nature of this event, which explains its traumatic effect and stands as an emblem of that auto-immunity, which is the fundamental characteristic of present times, in this era of globalisation.

description: This thesis examines the effects of Culture, the Unified Theory of Acceptance and Use of Technology (UTAUT), Expectation Confirmation Theory (ECT) and Technology Readiness (TR) on the satisfaction and usage continuance intention of Internet banking customers within the Saudi Arabian context. The aim is to develop and test a new framework for use in determining the factors that affect Internet banking customers’ actual usage behaviours, with a special focus on the role of cognitive processes, and cultural and personal psychological traits. This research uses cross-sectional survey questionnaire methods within a quantitative approach. 261 valid responses were received. Structural Equation Modelling (SEM) was used to test the hypothesised relationships within the research model in Analysis of Moment Structures (AMOS 20) software. ECT is well established in conventional marketing literature and explains how cognitive beliefs and affects lead to customers’ repurchasing behaviour. It was first adopted for the Information Systems (IS) context and then customised to explain IS continuance intention behaviour. However, previous ECT customisations in the IS context present a significant knowledge gap because technology-based services are sensitive to individuals’ psychological traits, which ECT does not account for. This research integrates psychological traits and culture into the ECT framework to explain customer satisfaction and continuance intentions in the context of Internet banking usage. It combines ECT with the UTAUT in order to expand ECT to include more cognitive beliefs. Then it integrates TR and Culture to account for psychological and sociological traits. The results present a new contribution to the body of knowledge by validating a theoretically backed integration of the above models into one structural model. This model broadens the understanding of the factors that influence IS satisfaction and usage continuance intention. Compared to previous studies, the explanatory power of this model is a major improvement, with an R2 of (0.61) for usage continuance intention.

Uniqueness of Lagrangian mean curvature flow and minimal immersions with free boundary
Creators: name: Pang, Chao
Publisher: name: University of British Columbia
Year: 2013

description: In this thesis we investigate some problems on the uniqueness of mean curvature flow and the existence of minimal surfaces, by geometric and analytic methods. A summary of the main results is as follows. (i) The special Lagrangian submanifolds form a very important class of minimal submanifolds, which can be constructed via the method of mean curvature flow. In the graphical setting, the potential function for the Lagrangian mean curvature ow satisfies a fully nonlinear parabolic equation [formula omitted] where the ⋋j's are the eigenvalues of the Hessian D²u. We prove a uniqueness result for unbounded solutions of (1) without any growth condition, via the method of viscosity solutions ([4], [13]): for any continuous u₀ in ℝn, there is a unique continuous viscosity solution to (1) in ℝn x [0;∞). (ii) Let N be a complete, homogeneously regular Riemannian manifold of dimN ≥ 3 and let M be a compact submanifold of N. Let Ʃ be a compact Riemann surface with boundary. A branched immersion u : (Σ,∂Σ) → (N,M) is a minimal surface with free boundary in M if u(Σ) has zero mean curvature and u(Σ) is orthogonal to M along u(∂Σ)⊑ M. We study the free boundary problem for minimal immersions of compact bordered Riemann surfaces and prove that Σ if is not a disk, then there exists a free boundary minimal immersion of Σ minimizing area in any given conjugacy class of a map in C⁰(Σ,∂Σ;N,M) that is incompressible; the kernel of i* : π₁(M) → π₁(N) admits a generating set such that each member is freely homotopic to the boundary of an area minimizing disk that solves the free boundary problem. (iii) Under certain nonnegativity assumptions on the curvature of a 3-manifold N and convexity assumptions on the boundary M=∂N, we investigate controlling topology for free boundary minimal surfaces of low index: • We derive bounds on the genus, number of boundary components; • We prove a rigidity result; • We give area estimates in term of the scalar curvature of N.

description: We study the strong localization of hard core bosons. Using a locator expansion we find that in the insulator, unlike for typical fermion problems, nearly all low-energy scattering paths come with positive amplitudes and hence interfere constructively. As a consequence, the localization length of bosonic excitations shrinks when the constructive interference is suppressed by a magnetic field, entailing an exponentially large positive magnetoresistance, opposite to and significantly stronger than the analogous effect in fermions. Within the forward scattering approximation, we find that the lowest energy excitations are the most delocalized. A similar analysis applied to random field Ising models suggests that the ordering transition is due to a delocalization initiated at zero energy rather than due to the closure of a mobility gap in the paramagnet.

description: Community detection is an important tool for exploring and classifying the properties of large complex networks and should be of great help for spatial networks. Indeed, in addition to their location, nodes in spatial networks can have attributes such as the language for individuals, or any other socio-economical feature that we would like to identify in communities. We discuss in this paper a crucial aspect which was not considered in previous studies which is the possible existence of correlations between space and attributes. Introducing a simple toy model in which both space and node attributes are considered, we discuss the effect of space-attribute correlations on the results of various community detection methods proposed for spatial networks in this paper and in previous studies. When space is irrelevant, our model is equivalent to the stochastic block model which has been shown to display a detectability-non detectability transition. In the regime where space dominates the link formation process, most methods can fail to recover the communities, an effect which is particularly marked when space-attributes correlations are strong. In this latter case, community detection methods which remove the spatial component of the network can miss a large part of the community structure and can lead to incorrect results.

description: Using Regge calculus, we construct a Regge differential equation for the time evolution of the scale factor $a(t)$ in the Einstein-de Sitter cosmology model (EdS). We propose two modifications to the Regge calculus approach: 1) we allow the graphical links on spatial hypersurfaces to be large, as in direct particle interaction when the interacting particles reside in different galaxies, and 2) we assume luminosity distance $D_L$ is related to graphical proper distance $D_p$ by the equation $D_L = (1+z)\sqrt{\overrightarrow{D_p}\cdot \overrightarrow{D_p}}$, where the inner product can differ from its usual trivial form. The modified Regge calculus model (MORC), EdS and $Λ$CDM are compared using the data from the Union2 Compilation, i.e., distance moduli and redshifts for type Ia supernovae. We find that a best fit line through $\displaystyle \log{(\frac{D_L}{Gpc})}$ versus $\log{z}$ gives a correlation of 0.9955 and a sum of squares error (SSE) of 1.95. By comparison, the best fit $Λ$CDM gives SSE = 1.79 using $H_o$ = 69.2 km/s/Mpc, $Ω_{M}$ = 0.29 and $Ω_Λ$ = 0.71. The best fit EdS gives SSE = 2.68 using $H_o$ = 60.9 km/s/Mpc. The best fit MORC gives SSE = 1.77 and $H_o$ = 73.9 km/s/Mpc using $R = A^{-1}$ = 8.38 Gcy and $m = 1.71\times 10^{52}$ kg, where $R$ is the current graphical proper distance between nodes, $A^{-1}$ is the scaling factor from our non-trival inner product, and $m$ is the nodal mass. Thus, MORC improves EdS as well as $Λ$CDM in accounting for distance moduli and redshifts for type Ia supernovae without having to invoke accelerated expansion, i.e., there is no dark energy and the universe is always decelerating.

description: We study holographic RG flow of the shear viscosity tensor of anisotropic, strongly coupled N=4 super-Yang-Mills plasma by using its type IIB supergravity dual in anisotropic bulk spacetime. We find that the shear viscosity tensor has three independent components in the anisotropic bulk spacetime away from the boundary, and one of the components has a non-trivial RG flow while the other two have a trivial one. For the component of the shear viscosity tensor with non-trivial RG flow, we derive its RG flow equation, and solve the equation analytically to second order in the anisotropy parameter 'a'. We derive the RG equation using the equation of motion, holographic Wilsonian RG method, and Kubo's formula. All methods give the same result. Solving the equation, we find that the ratio of the component of the shear viscosity tensor to entropy density 'eta/s' flows from above '1/4pi' at the horizon (IR) to below '1/4pi' at the boundary (UV) where it violates the holographic shear viscosity (Kovtun-Son-Starinets) bound and where it agrees with the other longitudinal component.

Dirichlet boundary conditions in type IIB superstring theory and fermionic T-duality

description: In this article we investigate the relation between consequences of Dirichlet boundary conditions (momenta noncommutativity and parameters of the effective theory) and background fields of fermionic T-dual theory. We impose Dirichlet boundary conditions on the endpoints of the open string propagating in background of type IIB superstring theory with constant background fields. We showed that on the solution of the boundary conditions the momenta become noncommutative, while the coordinates commute. Fermionic T-duality is also introduced and its relation to noncommutativity is considered. We use compact notation so that type IIB superstring formally gets the form of the bosonic one with Grassman variables. Then momenta noncommutativity parameters are fermionic T-dual fields. The effective theory, the initial theory on the solution of boundary conditions, is bilinear in the effective coordinates, odd under world-sheet parity transformation. The effective metric is equal to the initial one and terms with the effective Kalb-Ramond field vanish.
title: DEPRECATED: MEN WITH LEARNING DISABILITIES WHO SEXUALLY OFFEND AND STAFF ATTRIBUTIONS ABOUT SEXUALLY ABUSIVE BEHAVIOUR
Creators: name: Yates, Caroline
Publisher: name: University of Plymouth
Year: 1995

description: This study was to designed, in two parts, to investigate: 1. Whether the attributions about sexually abusive behaviour, made by staff in learning disabilities services, differed according to whether or not the perpetrator had a learning disability, and if these attributions served to hinder the identification, acknowledgement and reporting of sexually abusive behaviour performed by men with learning disabilities. 2. The number of clients referred to therapists in learning disabilities services, over a two year period, for sexually abusive behaviour, client and offence characteristics, and the referral process. Information was sought regarding therapists' perceived reasons for delayed referrals, and the impact this had on ease of treatment. A questionnaire employing vignettes was constructed to measure staff attributions, about offenders and their behaviour, on dimensions of impulsivity, level of understanding, sexual motivation, and the extent to which behaviour was influenced by the victim, and other personal and external factors. Results of the questionnaire were analysed using ANOVA. Significant differences in staff responses were found on all measures. Results suggest that peoples' perceptions of the perpetrator with a learning disability are less likely to invoke attributions of responsibility and blame and thus may serve to hinder the identification, acknowledgement and reporting of abusive behaviour. The results of the survey of therapists indicate that clients referred for sexually abusive behaviours share similar offence characteristics with offenders in the general population in terms of the range of behaviours exhibited, and multiple offending. These results also show that most referrals to therapists are delayed, and that the delay is . perceived to be due to staff not considering the behaviour to be 'primarily sexual' in nature, and 'excusing' the behaviour because of the individual's learning disability or 'other' personal characteristics. Links between the two parts of the study are drawn and these and other findings are discussed in relation to practice and implications for future research.

Symplectically-invariant soliton equations from non-stretching geometric curve flows

description: A moving frame formulation of geometric non-stretching flows of curves in the Riemannian symmetric spaces $Sp(n+1)/Sp(1)\times Sp(n)$ and $SU(2n)/Sp(n)$ is used to derive two bi-Hamiltonian hierarchies of symplectically-invariant soliton equations. As main results, multi-component versions of the sine-Gordon (SG) equation and the modified Korteweg-de Vries (mKdV) equation exhibiting $Sp(1)\times Sp(n-1)$ invariance are obtained along with their bi-Hamiltonian integrability structure consisting of a shared hierarchy of symmetries and conservation laws generated by a hereditary recursion operator. The corresponding geometric curve flows in $Sp(n+1)/Sp(1)\times Sp(n)$ and $SU(2n)/Sp(n)$ are shown to be described by a non-stretching wave map and a mKdV analog of a non-stretching Schrödinger map.

Answer to a question on $A$-groups, arisen from the study of Steinitz classes

description: In this short note we answer to a question of group theory from arXiv:0910.5080. In that paper the author describes the set of realizable Steinitz classes for so-called $A'$-groups of odd order, obtained iterating some direct and semidirect products. It is clear from the definition that $A'$-groups are solvable $A$-groups, but the author left as an open question whether the converse is true. In this note we prove the converse when only two prime numbers divide the order of the group, but we show it to be false in general, producing a family of counterexamples which are metabelian and with exactly three primes dividing the order. Steinitz classes which are realizable for such groups in the family are computed and verified to form a group.

description: This paper presents an overview of current and potential applications of living technology to some urban problems. Living technology can be described as technology that exhibits the core features of living systems. These features can be useful to solve dynamic problems. In particular, urban problems concerning mobility, logistics, telecommunications, governance, safety, sustainability, and society and culture are presented, while solutions involving living technology are reviewed. A methodology for developing living technology is mentioned, while supraoptimal public transportation systems are used as a case study to illustrate the benefits of urban living technology. Finally, the usefulness of describing cities as living systems is discussed.
