description: We survey recent results on multiple transitivity of automorphism groups of affine algebraic varieties. We consider the property of infinite transitivity of the special automorphism group, which is equivalent to flexibility of the corresponding affine variety. These properties have important algebraic and geometric consequences. At the same time they are fulfilled for wide classes of varieties. Also we study situations where infinite transitivity takes place for automorphism groups generated by finitely many one-parameter subgroups. In the appendices to the paper, the results on infinitely transitive actions in complex analysis and in combinatorial group theory are discussed.

description: We study the effects of initial state fluctuations on the dynamical evolution of heavy quarks inside a quark-gluon plasma created in relativistic heavy-ion collisions. The evolution of heavy quarks in QGP matter is described utilizing a modified Langevin equation that incorporates the contributions from both collisional and radiative energy loss. The spacetime evolution of the fireball medium is simulated with a (2+1)-dimensional viscous hydrodynamic model. We find that when the medium traversed by the heavy quark contains a fixed amount of energy, heavy quarks tend to lose more energy for greater fluctuations of the medium density. This may result in a larger suppression of heavy flavor observables in a fluctuating QGP matter than in a smooth one. The possibility of using hard probes to infer the information of initial states of heavy-ion collisions is discussed.

description: Let $f \in Q(z)$ be a polynomial or rational function of degree 2. A special case of Morton and Silverman's Dynamical Uniform Boundedness Conjecture states that the number of rational preperiodic points of $f$ is bounded above by an absolute constant. A related conjecture of Silverman states that the canonical height $\hat{h}_f(x)$ of a non-preperiodic rational point $x$ is bounded below by a uniform multiple of the height of $f$ itself. We provide support for these conjectures by computing the set of preperiodic and small height rational points for a set of degree 2 maps far beyond the range of previous searches.

description: This case focuses on Nick Hungerford's attempt to raise capital for his FinTech start-up, Financial Butler, (later renamed Nutmeg). The concept is a digital platform offering a revolutionary, transparent and fair service to an 'untapped' market segment currently not served by wealth managers, 'democratising' access to quality financial advice for individuals. The case describes how the protagonist evaluates the opportunity, creates a strategy to raise funding for the business and reacts to obstacles in his path to creating a FinTech firm. It is split into three parts. The 'A' case provides the background to the venture, data on the industry and market and examples of Hungerford's first pitch. The 'B' case reveals that Hungerford's many pitches have ended in failure, obliging him to refine his approach; the 'C' case reveals how he finally achieved success on his 48th pitch to a venture capital firm.

description: When Fati Ibrahim lost her husband and eldest son after Boko Haram insurgents attacked their town of Gwoza in north-eastern Nigeria, she wasn't alone. She was one of dozens of women who lost family members, homes and livelihoods. Three years later, she found herself queueing outside a tent near Maiduguri, the city at the epicentre of the uprising, waiting to go inside and get the help she still desperately needed. But instead of the food, shelter or medicine that many relief efforts focus on, she - and the many women like her -  were waiting for something less tangible: someone to help them process their trauma.

Non-planar extensions of subdivisions of planar graphs

Subjects: subject: Combinatorics (math.CO)

description: Almost $4$-connectivity is a weakening of $4$-connectivity which allows for vertices of degree three. In this paper we prove the following theorem. Let $G$ be an almost $4$-connected triangle-free planar graph, and let $H$ be an almost $4$-connected non-planar graph such that $H$ has a subgraph isomorphic to a subdivision of $G$. Then there exists a graph $G'$ such that $G'$ is isomorphic to a minor of $H$, and either (i) $G'=G+uv$ for some vertices $u,v\in V(G)$ such that no facial cycle of $G$ contains both $u$ and $v$, or (ii) $G'=G+u_1v_1+u_2v_2$ for some distinct vertices $u_1,u_2,v_1,v_2\in V(G)$ such that $u_1,u_2,v_1,v_2$ appear on some facial cycle of $G$ in the order listed. This is a lemma to be used in other papers. In fact, we prove a more general theorem, where we relax the connectivity assumptions, do not assume that $G$ is planar, and consider subdivisions rather than minors. Instead of face boundaries we work with a collection of cycles that cover every edge twice and have pairwise connected intersection. Finally, we prove a version of this result that applies when $G\backslash X$ is planar for some set $X\subseteq V(G)$ of size at most $k$, but $H\backslash Y$ is non-planar for every set $Y\subseteq V(H)$ of size at most $k$.

BPS center vortices in nonrelativistic SU(N) gauge models with adjoint Higgs fields

description: In this work, we propose a class of SU(N) Yang-Mills models, with adjoint Higgs fields, that accept BPS center vortex equations. The lack of a local magnetic flux that could serve as an energy bound is circumvented by including a new term in the energy functional. This term tends to align, in the Lie algebra, the magnetic field and one of the adjoint Higgs fields. Finally, a reduced set of equations for the center vortex profile functions is obtained (for N=2,3). In particular, Z(3) BPS vortices come in three colours and three anticolours, obtained from an ansatz based on the defining representation and its conjugate.

description: The cocrystallization of salicylamide (2-hydroxybenzamide, SMD) and ethenzamide (2-ethoxybenzamide, EMD) with aromatic carboxylic acids was examined both experimentally and theoretically. The supramolecular synthesis taking advantage of the droplet evaporative crystallization (DEC) technique was combined with powder diffraction and vibrational spectroscopy as the analytical tools. This led to identification of eleven new cocrystals including pharmaceutically relevant coformers such as mono- and dihydroxybenzoic acids. The cocrystallization abilities of SMD and EMD with aromatic carboxylic acids were found to be unexpectedly divers despite high formal similarities of these two benzamides and ability of the R2,2(8) heterosynthon formation. The source of diversities of the cocrystallization landscapes is the difference in the stabilization of possible conformers by adopting alternative intramolecular hydrogen boding patterns. The stronger intramolecular hydrogen bonding the weaker affinity toward intermolecular complexation potential. The substituent effects on R2,2(8) heterosynthon properties are also discussed.

description: Recently the question of whether the D-Wave processors exhibit large-scale quantum behavior or can be described by a classical model has attracted significant interest. In this work we address this question by studying a 503 qubit D-Wave Two device in the "black box" model, i.e., by studying its input-output behavior. Our work generalizes an approach introduced in Boixo et al. [Nat. Commun. 4, 2067 (2013)], and uses groups of up to 20 qubits to realize a transverse Ising model evolution with a ground state degeneracy whose distribution acts as a sensitive probe that distinguishes classical and quantum models for the D-Wave device. Our findings rule out all classical models proposed to date for the device and provide evidence that an open system quantum dynamical description of the device that starts from a quantized energy level structure is well justified, even in the presence of relevant thermal excitations and a small value of the ratio of the single-qubit decoherence time to the annealing time.

description: (1) Introduction: New technologies that leverage gas hydrates phenomena include carbon capture and sequestrations. These processes are often semi-continuous and require regulation of the system's flow properties for proper operation. Accurate computational models for the viscosity of carbon dioxide hydrate systems at pre-nucleation conditions can be important for process design and control of such technologies. (2) Methods: This work validates the viscosity predictions of molecular dynamics simulations using previously measured experimental data. The TIP4P/Ice force field was used to model water, while the EPM2, TraPPE, and Zhang force fields were used for carbon dioxide. The Green-Kubo and Einstein formulations of viscosity and diffusivity were used in this work. (3) Results: All force fields overpredicted viscosity when compared to experimental data, but EPM2 resulted in lower discrepancies. Additionally, EPM2 was determined to model molecular behavior expected from the macroscopic trends in viscosity with respect to temperature and pressure. (4) Conclusions: The EPM2 force field more accurately predicted the viscosity of carbon dioxide hydrates systems at pre-nucleation conditions relative to TraPPE and Zhang.

description: La selezione dei documenti cartacei destinati a costituire, o ad arricchire, la collezione digitale di una biblioteca tradizionale, o ibrida, costituisce spesso il movente del progetto di digitalizzazione, ne definisce l’identità, ne determina in massima parte il successo e, non ultimo, valorizza e gratifica le competenze più squisitamente culturali del bibliotecario. Tuttavia tale selezione va collocata nel quadro di una consapevole progettazione complessiva di allestimento ed esercizio nel tempo della collezione digitale. Essa va svolta in una dialettica serrata con molteplici fattori di ordine culturale, biblioteconomico, tecnologico, legale, economico e deve rispondere alle finalità definite per il progetto di digitalizzazione nel suo complesso, nel quadro della mission della biblioteca. I criteri maggiormente diffusi a livello internazionale tendono a realizzare un equilibrio virtuoso tra il potenziamento dell’accesso ai documenti da parte di un’utenza allargata, e la preservazione dei documenti originali, siano essi materiali di ampia fruizione oppure materiali che si intende valorizzare sfruttando le potenzialità dell’ambiente digitale. L’intervento non intende proporre pertanto una griglia precoordinata di criteri di selezione, bensì una serie di elementi di riflessione derivanti dall’analisi dei diversi elementi che compongono la biblioteca digitale (la comunità degli utenti, i documenti e i contenuti, i servizi bibliotecari, la tecnologia disponibile, le risorse economiche e umane); tali elementi potranno ispirare l’assortimento dei criteri di selezione funzionali al progetto che si intende realizzare.
Nonostante manchi una letteratura specifica e la sua trattazione venga assimilata agli altri documenti testuali, anche nell’ambito della digitalizzazione il materiale musicale scritto presenta peculiarità che si riflettono sulle tecniche di acquisizione, sulle possibilità di fruizione a video o a stampa, sull’integrazione con documentazione correlata (audio, libretti etc.), sulla gestione del diritto d’autore, sulla scelta delle entità (FRBR) che si desidera riprodurre in formato digitale, sull’interazione con l’offerta complessiva di musica disponibile in Internet dove il contatto tra produttori di contenuti e fruitori è molto stretto e non è facile per le biblioteche inserire le proprie offerte di mediazione.

description: The analysis of nonlinear dynamics is an important issue in numerous fields of science. In this study, we propose a new method to analyze the time series data using persistent homology (PH). The key idea is the application of PH to the distance matrix. Using this method, we can obtain the topological features embedded in the trajectories. We apply this method to the logistic map, Rössler system, and electrocardiogram data. The results reveal that our method can effectively identify nonlocal characteristics of the attractor and can classify data based on the amount of noise.

description: The electronic spectrum of alizarin (AZ) in methanol solution was measured and used as reference data for color prediction. The visible part of the spectrum was modelled by different DFT functionals within the TD-DFT framework. The results of a broad range of functionals applied for theoretical spectrum prediction were compared against experimental data by a direct color comparison. The tristimulus model of color expressed in terms of CIE XYZ and CIE Lab parameters was applied both to experimental and predicted spectra. It was found that the HSE03 method along with the 6-31G(d,p) basis set provides the most accurate color prediction, much better than other commonly used functionals such as B3LYP, CAM-B3LYP or PBE0. Besides, the influence of potential errors, introduced by theoretical predictions on color estimation, was examined for different wavelengths. The obtained results showed that color prediction is significantly dependent on the type of basis set and functional applied. The proposed methodology provides a simple, straightforward and more reliable way of theoretical protocols validation than just a comparison of experimental and estimated values of maximum absorbance wavelength.

As an application, simply-connected, rationally-elliptic manifolds admitting slice-maximal torus actions are classified up to equivariant rational homotopy. The case where the rational-ellipticity hypothesis is replaced by non-negative curvature is also discussed, and the Bott Conjecture in the presence of a slice-maximal torus action is proved.

Our construction applies to an explicit and general class of initial conditions, including the lattice configuration $\{x_i\}=\mathbb{Z}$ and the sine process. We further show the convergence of the finite to infinite-dimensional SDE. This convergence concludes the determinantal formula of Katori and Tanemura (2010) for the solution of this SDE at $β=2$.

description: Freedman's inequality is a supermartingale counterpart to Bennett's inequality. This result shows that the tail probabilities of a supermartingale is controlled by the quadratic characteristic and a uniform upper bound for the supermartingale difference sequence. Replacing the quadratic characteristic by $\textrm{H}_k^y:= \sum_{i=1}^k\left(\mathbf{E}(ξ_i^2 |\mathcal{F}_{i-1}) +ξ_i^2\textbf{1}_{\{|ξ_i|> y\}}\right),$ Dzhaparidze and van Zanten (\emph{Stochastic Process. Appl.}, 2001) have extended Freedman's inequality to martingales with unbounded differences. In this paper, we prove that $\textrm{H}_k^y$ can be refined to $\textrm{G}_k^{y} :=\sum_{i=1}^k \left( \mathbf{E}(ξ_i^2\textbf{1}_{\{ξ_i \leq y\}} |\mathcal{F}_{i-1}) + ξ_i^2\textbf{1}_{\{ξ_i> y\}}\right).$ Moreover, we also establish two inequalities of type Dzhaparidze and van Zanten. These results extend Sason's inequality (\emph{Statist. Probab. Lett.}, 2012) to the martingales with possibly unbounded differences and establish the connection between Sason's inequality and De la Peña's inequality (\emph{Ann.\ Probab.,} 1999). An application to self-normalized deviations is given.

description: The output of climate models is usually validated with reference data from observations. Model data and commonly used observational data must be obtained from different sources. Model data stem from research institutions, observational data often from public authorities. To proceed with further analysis all data must be standardized and brought to the same format. The objective of this pilot is to bring observational data closer to the model output and to increase number of users by making data from public authorities more easily accessible. The pilot will exemplarily integrate the German Weather Service (DWD) reanalysis dataset COSMO-REA6 to the infrastructure of the Earth System Grid Federation (ESGF). The developed workflow will be documented and serves as a blueprint for further integrations of datasets from DWD or other public authorities.

description: The electronic spectrum of alizarin (AZ) in methanol solution was measured and used as reference data for color prediction. The visible part of the spectrum was modelled by different DFT functionals within the TD-DFT framework. The results of a broad range of functionals applied for theoretical spectrum prediction were compared against experimental data by a direct color comparison. The tristimulus model of color expressed in terms of CIE XYZ and CIE Lab parameters was applied both to experimental and predicted spectra. It was found that the HSE03 method along with the 6-31G(d,p) basis set provides the most accurate color prediction, much better than other commonly used functionals such as B3LYP, CAM-B3LYP or PBE0. Besides, the influence of potential errors, introduced by theoretical predictions on color estimation, was examined for different wavelengths. The obtained results showed that color prediction is significantly dependent on the type of basis set and functional applied. The proposed methodology provides a simple, straightforward and more reliable way of theoretical protocols validation than just a comparison of experimental and estimated values of maximum absorbance wavelength.

description: Driven dissipative steady state entanglement schemes take advantage of coupling to the environment to robustly prepare highly entangled states. We present a scheme for two trapped ions to generate a maximally entangled steady state with fidelity above 0.99, appropriate for use in quantum protocols. Furthermore, we extend the scheme by introducing detection of our dissipation process, significantly enhancing the fidelity. Our scheme is robust to anomalous heating and requires no sympathetic cooling.

description: Submitted as a white paper to the National Academies of Sciences, Engineering, and Medicine ad hoc Committee on Astrobiology Science Strategy for Life in the Universe, National Research Council, Washington, DC, 2018.

Summary: Not knowing exactly what to look for, Astrobiology should embrace, and prioritize, all scientifically plausible and technologically feasible search strategies for both biosignatures and technosignatures. There is no scientific justification for excluding SETI, or any other technosignature modality, from the suite of astrobiological investigations. Arguments based on political sensitivities or apparent access to other funding sources are inappropriate. In this white paper, we argue for a level playing field.

description: In general, gradient estimates are very important and necessary for deriving convergence results in different geometric flows, and most of them are obtained by analytic methods. In this paper, we will apply a stochastic approach to systematically give gradient estimates for some important geometric quantities under the Ricci flow, the mean curvature flow, the forced mean curvature flow and the Yamabe flow respectively. Our conclusion gives another example that probabilistic tools can be used to simplify proofs for some problems in geometric analysis.

description: Green transportation and renewable energy production have attracted a global attention due to the needs of decreasing the environmental impact and still sustain increased energy needs. In this framework, the aircraft and airports are facing a profound renovations towards green technologies, among which the electrical ones are playing a central role. This paper explores how a Smart Transformer can upgrade the existing airport power system, enabling an efficient interface for renewable energy, electric vehicles and the future hybrid/electric aircraft, substituting the ground power units and enabling a smarter behavior of the electrical grid.

description: We derive several results in classical Euclidean elementary geometry using the steering ellipsoid formalism from quantum mechanics. This gives a physically motivated derivation of very non-trivial geometric results, some of which are entirely new. We consider a sphere of radius $r$ contained inside another sphere of radius $R$, with the sphere centres separated by distance $d$. When does there exist a nested tetrahedron circumscribed about the smaller sphere and inscribed in the larger? We derive the Grace-Danielsson inequality $d^2 \leq (R+r)(R-3r)$ as the sole necessary and sufficient condition for the existence of a nested tetrahedron. Our method also gives the condition $d^2 \leq R(R-2r)$ for the existence of a nested triangle in the analogous 2-dimensional scenario. These results imply the Euler inequality in 2 and 3 dimensions. Furthermore, we formulate a new inequality that applies to the more general case of ellipses and ellipsoids.

description: The idea forONk originated in 2012 when six-year-old Mike asked his father, Sam Ke, one night, 'Can we make a computer that is simple and fun?' Soon afterwards, a team of three - Alex Bell, Joe Costa and Sam Ke - came together to answer the call. The mission: to give young people - and the young at heart - a simple, fun way to make and play with technology and take control of the world around them. At the core of the proposed offering is a hardware and software kit that can be assembled to create an easy-to-program computer. They named the company ONk to epitomise the spirit of their idea: build a computer, turn it ON and hit any KEY, so you could immediately start to code.

description: We present a reduction of the function field Mordell-Lang conjecture to the function field Manin-Mumford conjecture, in all characteristics, via model theory, but avoiding recourse to the dichotomy theorems for (generalized) Zariski structures. In this version 2, the quantifier elimination result in positive characteristic is extended from simple abelian varieties to all abelian varieties, completing the main theorem in the positive characteristic case. In version 3, some corrections are made to the proof of quantifier elimination in positive characteristic, and the paper is substantially reorganized.

description: Honorable Mention
description: Salt crystals like these grow from colorless, empty-looking solutions. Inside each solution chemicals are dissolved in water. When the water evaporates these striking chemical patterns are left behind.Depending on the type of salt and the way the liquid evaporates, beautiful crystals like these flowery patterns can form. The shape of each flower gives valuable information about the internal structure of the crystals and how they formed.In this experiment researchers wanted to observe how nanoparticles assemble into microscopic crystals. These crystals are built from molecules which researchers use to make and assemble nanoparticles. The better we understand nano-scale building blocks and how they work, the more effectively we can use them to design new materials, make smaller devices, and more specifically target diseases.Department of Materials Science & Engineering Tools & Techniques: Scanning Electron Microscope + colored in Photoshop
The stellar mass function and star formation rate-stellar mass relation of galaxies at z ~ 4 - 7

description: We investigate the evolution of the star formation rate-stellar mass relation (SFR-M*) and Galaxy Stellar Mass Function (GSMF) of z ~ 4-7 galaxies, using cosmological simulations run with the smoothed particle hydrodynamics code P-GADGET3(XXL). We explore the effects of different feedback prescriptions (supernova driven galactic winds and AGN feedback), initial stellar mass functions and metal cooling. We show that our fiducial model, with strong energy-driven winds and early AGN feedback, is able to reproduce the observed stellar mass function obtained from Lyman-break selected samples of star forming galaxies at redshift 6 < z < 7. At z ~ 4, observed estimates of the GSMF vary according to how the sample was selected. Our simulations are more consistent with recent results from K-selected samples, which provide a better proxy of stellar masses and are more complete at the high mass end of the distribution. We find that in some cases simulated and observed SFR-M* relations are in tension, and this can lead to numerical predictions for the GSMF in excess of the GSMF observed. By combining the simulated SFR(M*) relationship with the observed star formation rate function at a given redshift, we argue that this disagreement may be the result of the uncertainty in the SFR-M* (Luv-M*) conversion. Our simulations predict a population of faint galaxies not seen by current observations.

Gap and rigidity theorems of $λ$-hypersurfaces

description: We study $λ$-hypersurfaces that are critical points of a Gaussian weighted area functional $\int_Σ e^{-\frac{|x|^2}{4}}dA$ for compact variations that preserve weighted volume. First, we prove various gap and rigidity theorems for complete $λ$-hypersurfaces in terms of the norm of the second fundamental form $|A|$. Second, we show that in one dimension, the only smooth complete and embedded $λ$-hypersurfaces in $\mathbb{R}^2$ with $λ\geq 0$ are lines and round circles. Moreover, we establish a Bernstein type theorem for $λ$-hypersurfaces which states that smooth $λ$-hypersurfaces that are entire graphs with polynomial volume growth are hyperplanes. All the results can be viewed as generalizations of results for self-shrinkers.

description: We consider the Lagrangian of a vector field with derivative self-interactions with a priori arbitrary coefficients. Starting with a flat space-time we show that for a special choice of the coefficients of the self-interactions the ghost-like pathologies disappear. For this we use the degeneracy condition of the Hessian. This constitutes the Galileon-type generalization of the Proca action with only three propagating physical degrees of freedom. The longitudinal mode of the vector field is associated to the usual Galileon interactions for a specific choice of the overall functions. In difference to a scalar Galileon theory, the generalized Proca field has more free parameters and purely intrinsic vector interactions. We then extend this analysis to a curved background. The resulting theory is the Horndeski Proca action with second order equations of motion on curved space-times.
