description: Monitoring the spatio-temporal variations of surface chlorophyll-a concentration (Chl, a proxy of phytoplankton biomass) greatly benefited from the availability of continuous and global ocean color satellite measurements from 1997 onward. These two decades of satellite observations are however still too short to provide a comprehensive description of Chl variations at decadal to multi-decadal timescales. This paper investigates the ability of a machine learning approach (a non-linear statistical approach based on Support Vector Regression, hereafter SVR) to reconstruct global spatio-temporal Chl variations from selected surface oceanic and atmospheric physical parameters. With a limited training period (13 years), we first demonstrate that Chl variability from a 32- years global physical-biogeochemical simulation can generally be skillfully reproduced with a SVR using the model surface variables as input parameters. We then apply the SVR to reconstruct satellite Chl observations using the physical predictors from the above numerical model and show that the Chl reconstructed by this SVR more accurately reproduces some aspects of observed Chl variability and trends compared to the model simulation. This SVR is able to reproduce the main modes of interannual Chl variations depicted by satellite observations in most regions, including El Niño signature in the tropical Pacific and Indian Oceans. In stark contrast with the trends simulated by the biogeochemical model, it also accurately captures spatial patterns of Chl trends estimated by satellite data, with a Chl increase in most extratropical regions and a Chl decrease in the center of the subtropical gyres, although the amplitude of these trends are underestimated by half. Results from our SVR reconstruction over the entire period (1979–2010) also suggest that the Interdecadal Pacific Oscillation drives a significant part of decadal Chl variations in both the tropical Pacific and Indian Oceans. Overall, this study demonstrates that non-linear statistical reconstructions can be complementary tools to in situ and satellite observations as well as conventional physical-biogeochemical numerical simulations to reconstruct and investigate Chl decadal variability.

Overview

Les plus belles histoires d'amour ne meurent jamais. Elles continuent de vivre dans nos souvenirs et les coïncidences cruelles que notre esprit invente. Mais quand, pour Nathy, ces coïncidences deviennent trop nombreuses, doit-elle croire qu'il n'y a pas de hasard, seulement des rendez-vous ? Qui s'évertue à lui faire revivre cette parenthèse passionnelle qui a failli balayer sa vie ? Quand passé et présent se répètent au point de défier toute explication rationnelle, Nathy doit-elle admettre qu'on peut remonter le temps ? En quatre escales, Montréal, San Diego, Barcelone et Jakarta, dans un jeu de miroirs entre 1999 et 2019, J'ai dû rêver trop fort déploie une partition virtuose, mêlant passion et suspense, au plus près des cours qui battent trop fort.

description: The Material Plasma Exposure eXperiment (MPEX) is a steady state linear device with the goal to perform plasma material interaction (PMI) studies at future fusion reactor relevant conditions. A prototype of MPEX referred as Porto-MPEX is designed to carry out research and development related to source, heating and transport concepts on the planned full MPEX device. The auxiliary heating schemes in MPEX are based on cyclotron resonance heating with radio frequency (RF) waves. Ion cyclotron heating (ICH) and electron cyclotron heating (ECH) in MPEX are used to independently heat the ions and electrons and provide fusion divertor conditions ranging from sheath-limited to fully detached divertor regimes at a material target. A Hybrid Particle-In-Cell code- PICOS++ is developed and applied to understand the plasma parallel transport during ICH heating in MPEX Proto-MPEX to the target. With this tool, evolution of the distribution function of MPEX/Proto-MPEX ions is modeled in the presence of (1) Coulomb collisions, (2) volumetric particle sources and (3) quasi-linear RF-based ICH. The code is benchmarked against experimental data from Proto-MPEX and simulation data from B2.5 EIRENE. The experimental observation of density-drop near the target in Proto-MPEX and MPEX during ICH heating is demonstrated and explained via physics-based arguments using PICOS++ modeling. In fact, the density drops at the target during ICH in Proto-MPEX/MPEX to conserve the flux and to compensate for the increased flow during ICH. Furthermore, sensitivity scans of various plasma parameters with respect to ICH power are performed for MPEX to investigate its role on plasma transport and particle and energy fluxes at the target. Finally, we discuss the pathway to model ECH in MPEX using the Hybrid PIC formulation herein presented for kinetic electrons and fluid ions.

description: Images generated by high-resolution SAR have vast areas of application as they can work better in adverse light and weather conditions. One such area of application is in the military systems. This study is an attempt to explore the suitability of current state-of-the-art models introduced in the domain of computer vision for SAR target classification (MSTAR). Since the application of any solution produced for military systems would be strategic and real-time, accuracy is often not the only criterion to measure its performance. Other important parameters like prediction time and input resiliency are equally important. The paper deals with these issues in the context of SAR images. Experimental results show that deep learning models can be suitably applied in the domain of SAR image classification with the desired performance levels.

Read book online Impossible People: A Completely Average Recovery Story (English literature) 9780762468256 by Julia Wertz

In her keenly observed graphic memoir, Impossible People, celebrated cartoonist Julia Wertz chronicles her haphazard attempts at sobriety and the relentlessly challenging, surprisingly funny, and occasionally absurd cycle of addiction and recovery. Opening at the culmination of a disastrous trip to Puerto Rico, the first page of Impossible People finds Julia standing stupefied in the middle of the jungle beside a rental Jeep she's just crashed. From this moment, the story flashes back to the beginning of her five-year journey towards sobriety that includes group therapy sessions, relapses, an ill-fated relationship, terrible dates, and an unceremonious eviction from her New York City apartment. Far from the typical addiction narrative that follows an upward trajectory from rock bottom to rehab to recovery, Impossible People portrays the lesser told but more common story: That the road to recover is not always linear. With unflinching honesty, Wertz details the arduous, frustrating, and hilarious story of trying and failing and trying again.

Nonequilibrium transport and statistics of Schwinger pair production in Weyl semimetals

description: The non-equilibrium dynamics beyond linear response of Weyl semimetals is studied after a sudden switching on of a DC electric field. The resulting current is a nonmonotonic function of time, with an initial quick increase of polarization current followed by a power-law decay. Particle-hole creation à la Schwinger dominates for long times when the conduction current takes over the leading role, with the total current increasing again. The conductivity estimated from a dynamical calculation within a Drude picture agrees with the one obtained from Kubo's formula. The full distribution function of electron-hole pairs changes from Poissonian for short perturbations to a Gaussian in the long perturbation (Landau-Zener) regime. The vacuum persistence probability of high energy physics manifests itself in a finite probability of no pair creation and no induced current at all times.

description: In holographic duality, boundary states that have semiclassical bulk duals must obey inequalities, which bound their subsystems' von Neumann entropies. Hitherto known inequalities constrain entropies of reduced states on up to $N=5$ disjoint subsystems. Here we report one new such inequality, which involves $N=7$ disjoint regions. Our work supports a recent conjecture on the structure of holographic inequalities, which predicted the existence and schematic form of the new inequality. We explain the logic and educated guesses by which we arrived at the inequality, and comment on the feasibility of employing similar tactics in a more exhaustive search.

description: We present the results of the first Machine Learning Gravitational-Wave Search Mock Data Challenge (MLGWSC-1). For this challenge, participating groups had to identify gravitational-wave signals from binary black hole mergers of increasing complexity and duration embedded in progressively more realistic noise. The final of the 4 provided datasets contained real noise from the O3a observing run and signals up to a duration of 20 seconds with the inclusion of precession effects and higher order modes. We present the average sensitivity distance and runtime for the 6 entered algorithms derived from 1 month of test data unknown to the participants prior to submission. Of these, 4 are machine learning algorithms. We find that the best machine learning based algorithms are able to achieve up to 95% of the sensitive distance of matched-filtering based production analyses for simulated Gaussian noise at a false-alarm rate (FAR) of one per month. In contrast, for real noise, the leading machine learning search achieved 70%. For higher FARs the differences in sensitive distance shrink to the point where select machine learning submissions outperform traditional search algorithms at FARs $\geq 200$ per month on some datasets. Our results show that current machine learning search algorithms may already be sensitive enough in limited parameter regions to be useful for some production settings. To improve the state-of-the-art, machine learning algorithms need to reduce the false-alarm rates at which they are capable of detecting signals and extend their validity to regions of parameter space where modeled searches are computationally expensive to run. Based on our findings we compile a list of research areas that we believe are the most important to elevate machine learning searches to an invaluable tool in gravitational-wave signal detection.

The moduli space of instantons on an ALE space from 3d $\mathcal{N}=4$ field theories

Year: 2015
Subjects: subject: High Energy Physics - Theory (hep-th)

description: The moduli space of instantons on an ALE space is studied using the moduli space of $\mathcal{N}=4$ field theories in three dimensions. For instantons in a simple gauge group $G$ on $\mathbb{C}^2/\mathbb{Z}_n$, the Hilbert series of such an instanton moduli space is computed from the Coulomb branch of the quiver given by the affine Dynkin diagram of $G$ with flavour nodes of unitary groups attached to various nodes of the Dynkin diagram. We provide a simple prescription to determine the ranks and the positions of these flavour nodes from the order of the orbifold $n$ and from the residual subgroup of $G$ that is left unbroken by the monodromy of the gauge field at infinity. For $G$ a simply laced group of type $A$, $D$ or $E$, the Higgs branch of such a quiver describes the moduli space of instantons in projective unitary group $PU(n) \cong U(n)/U(1)$ on orbifold $\mathbb{C}^2/\hat{G}$, where $\hat{G}$ is the discrete group that is in McKay correspondence to $G$. Moreover, we present the quiver whose Coulomb branch describes the moduli space of $SO(2N)$ instantons on a smooth ALE space of type $A_{2n-1}$ and whose Higgs branch describes the moduli space of $PU(2n)$ instantons on a smooth ALE space of type $D_{N}$.

Overview

«¿Te mudarías a mi casa?» La primera vez que Jessie Inchauspé recibió esta petición de uno de sus lectores, a quien por supuesto no conocía, fue pocos días después de la publicación del libro que iba a cambiar por completo la conversación acerca de la nutrición y las dietas: La revolución de la glucosa. En su libro, Jessie había compartido numerosos y contundentes argumentos científicos acerca del modo en que la glucosa afecta a todos los aspectos de nuestra vida y nuestra salud, así como trucos sencillos para aprender a manejarnos con sus efectos. Tras esa petición y el gran éxito internacional de su obra, llegaron muchas más? Pero, ¿por qué tantas ofertas para mudarse a casa de desconocidos? Porque sus seguidores querían que estuviera a su lado para ayudarles a poner en práctica la ciencia de La revolución de la glucosa, día a día, comida a comida. Querían un plan. Un libro práctico, recetas, ánimo e inspiración. Este libro es el resultado de tantas y tantas de estas peticiones. En él, Jessie comparte sus trucos, recetas, listas de la compra y planes, tal y como lo haría con un buen amigo o un familiar. Se trata de una guía que abarca 4 semanas con sus 100 recetas favoritas que ayudará a los lectores a persistir en la práctica, a equilibrar sus niveles de glucosa y a empezar a sentirse mejor que nunca. El 90 % de la población vive con niveles de glucosa inestables, y la mayoría ni siquiera lo sabe, aunque a todos nos resulten familiares los síntomas: antojos, fatiga crónica, hambre constante, inflamación, problemas de sueño, problemas hormonales? Sabemos ya que empezaremos a sentimos mejor y recuperemos nuestros niveles de energía normales cuando aplanamos la curva de la glucosa. Pero, ¿cómo se hace eso? Desde luego, no a base de contar calorías ni de eliminar de la dieta ciertos grupos de alimentos. No, lo que vamos a hacer es utilizar una serie de principios basados en los últimos descubrimientos científicos: tomar un sabroso desayuno salado, empezar siempre las comidas con un buen plato de vegetales, incorporar el vinagre a nuestra dieta, movernos un poco después de comer? Una vez estos principios se convierten en hábitos recuperamos nuestra salud y nos sentimos mucho mejor.
Time-reversal symmetry adaptation in relativistic density matrix renormalization group algorithm

description: In the nonrelativistic Schrödinger equation, the total spin $S$ and spin projection $M$ are good quantum numbers. In contrast, spin symmetry is lost in the presence of spin-dependent interactions such as spin-orbit couplings in relativistic Hamiltonians. Previous implementations of relativistic density matrix renormalization group algorithm (R-DMRG) only employing particle number symmetry are much more expensive than nonrelativistic DMRG. Besides, artificial breaking of Kramers degeneracy can happen in the treatment of systems with odd number of electrons. To overcome these issues, we introduce time-reversal symmetry adaptation for R-DMRG. Since the time-reversal operator is antiunitary, this cannot be simply achieved in the usual way. We define a time-reversal symmetry-adapted renormalized basis and present strategies to maintain the structure of basis functions during the sweep optimization. With time-reversal symmetry adaptation, only half of the renormalized operators are needed and the computational costs of Hamiltonian-wavefunction multiplication and renormalization are reduced by half. The present construction of time-reversal symmetry-adapted basis also directly applies to other tensor network states without loops.

description: The multimerization of functional DNA alkylating agents has drawn significant, recent interest because these compounds are expected to generate enhanced levels of DNA cross-linked adducts, compared with their monomeric agents. Here we report the evaluation of 7- ,7′- ′-(1″,2″,9″,10″-tetrathia-cyclohexadecanyl-3″,8″,11″,16″-tetramethylenyl)tetrakismitomycin C (8), in which four mitomycin units are attached to the novel bis-disulfide linker, 3,8,11,16-tetrakis(aminomethyl)-1,2,9,10-tetrathia-cyclohexadecane. Compound 8 was designed to undergo preferential C(1) mitomycin activation under nucleophilic as well as under acidic and reductive conditions. We anticipated that treating 8 with nucleophiles would lead to bis-disulfide cleavage thus producing two mitomycin dimers (9) capable of generating DNA interstrand cross-links (ISC). The mitomycin units in 9 are tethered by a stable carbon backbone linkage. According to the procedure reported by Lee and coworkers ( , 61, 1749–1754 (2005)), we synthesized 8 and the reference mitomycin dimer, 7- ,7′- ′-(2″,7″-dihydroxy-1″,8″-octanediyl)bismitomycin C (15). Compound 8 was activated under acidic conditions thereby generating mitosene product 16, in which all four mitomycin units within the 16-membered ring were activated. Using the nucleophile Et P, we found that 8 underwent significantly enhanced mitosene production compared with its reference compound 15. We further demonstrated that under nucleophilic activation conditions 8 generated higher levels of DNA ISC than either 1 or 15. The cytotoxicities of 8 and 15 in a select tumor cell line were evaluated and compared with mitomycin C (1).

Overview

 

Els fills de les cinc famílies protagonistes deLa caiguda dels gegants forjaran el seu destí en els anys turbulents de la Segona Guerra Mundial, la guerra civil espanyola, el bombardeig de Pearl Harbor i l'era de la bomba atòmica.

Segon volum de la trilogia «The Century»

L'any 1933, Berlín és un focus d'agitació política i social. Lady Maud, ara esposa de Walter von Ulrich i mare de dos fills, publica articles en una revista setmanal que ridiculitzen el Partit Nazi, mentre que Walter manifesta la seva oposició en el Parlament. Sembla, però, que res no frenarà el poder ascendent del canceller Adolf Hitler. Quan Ethel Williams i el seu fill Lloyd visiten els von Ulrich, seran testimonis de la tirania i la repressió de la nova Alemanya.

El domini del Tercer Reich s'estendrà fins a França i més enllà de la frontera russa, mentre que, a Anglaterra, Lloyd Williams, activista polític com la seva mare, lluitarà amb l'exèrcit britànic per intentar frenar l'avenç dels nazis i s'allistarà a les brigades internacionals durant la guerra civil espanyola. Participarà a l'ofensiva de Saragossa i a la batalla de Belchite.

A Ty Gwyn, la mansió familiar dels Fitzherbert a Gal·les, s'allotjaran els oficial britànics i el tinent William Lloyd se sentirà atret per la dona d...

description: Thin film YIG (Y$_3$Fe$_5$O$_{12}$) is a prototypical material for experiments on thermally generated pure spin currents and the spin Seebeck effect. The 3-omega method is an established technique to measure the cross-plane thermal conductance of thin films, but can not be used in YIG/GGG (Ga$_3$Gd$_5$O$_{12}$) systems in its standard form. We use two-dimensional modeling of heat transport and introduce a technique based on Bayesian statistics to evaluate measurement data taken from the 3-omega method. Our analysis method allows us to study materials systems that have not been accessible with the conventionally used 3-omega analysis. Temperature dependent thermal conductance data of thin film YIG are of major importance for experiments in the field of spin-caloritronics. Here we show data between room temperature and 10 K for films covering a wide thickness range as well as the magnetic field effect on the thermal conductance between 10 K and 50 K.

description: Three new steroids dyscusins A-C (1-3), including a stigmastane-type sterol and two pregnanes, together with two known steroids were isolated from the leaves of Dysoxylum cumingianum (Meliaceae). Their structures were elucidated on the basis of extensive spectroscopic analyses. In a cytotoxicity assay, compound 1 showed ten-fold enhanced cytotoxicity against multi-drug resistant cancer cells (KB-C2) in the presence of 2.5 µM colchicine as compared with the absence of colchicine. This notable finding indicated that 1 possessed a multi-drug resistant reversal effect.

Restoration of four-dimensional diffeomorphism covariance in canonical general relativity: An intrinsic Hamilton-Jacobi approach

description: Classical background independence is reflected in Lagrangian general relativity through covariance under the full diffeomorphism group. We show how this independence can be maintained in a Hamilton-Jacobi approach that does not accord special privilege to any geometric structure. Intrinsic spacetime curvature based coordinates grant equal status to all geometric backgrounds. They play an essential role as a starting point for inequivalent semi-classical quantizations. The scheme calls into question Wheeler's geometrodynamical approach and the associated Wheeler-DeWitt equation in which three-metrics are featured geometrical objects. The formalism deals with variables that are manifestly invariant under the full diffeomorphism group. Yet, perhaps paradoxically, the liberty in selecting intrinsic coordinates is precisely as broad as is the original diffeomorphism freedom. We show how various ideas from the past five decades concerning the true degrees of freedom of general relativity can be interpreted in light of this new constrained Hamiltonian description. In particular, we show how the Kuchař multi-fingered time approach can be understood as a means of introducing full four-dimensional diffeomorphism invariants. Every choice of new phase space variables yields new Einstein-Hamilton-Jacobi constraining relations, and corresponding intrinsic Schrödinger equations. We show how to implement this freedom by canonical transformation of the intrinsic Hamiltonian. We also reinterpret and rectify significant work by B. Dittrich on the construction of `Dirac observables'.

Overview

In the latest riveting thriller from the #1 New York Times bestselling author, an international research station in the Coral Sea comes under siege during a geological disaster that triggers massive quakes, deadly tsunamis, and volcanic eruptions. To stop the world from burning, it’s up to Sigma Force to uncover a secret buried at the heart of our planet.  The Titan Project—an international research station off the coast of Australia—discovers a thriving zone of life in an otherwise dead sea. The area teems with a strange bioluminescent coral that defies science, yet holds great promise for the future. But the loss of a military submarine in the area triggers a brutal attack and sets in motion a geological disaster that destabilizes an entire region. Massive quakes, volcanic eruptions, and deadly tsunamis herald a greater cataclysm to come—for something is stirring miles under the ocean, a threat hidden for millennia. As seas turn toxic and coastlines burn, can Sigma Force stop what has been let loose—especially as an old adversary returns, hunting them and thwarting their every move? For any hope of success, Commander Gray Pierce must search for a key buried in the past, hidden deep in Aboriginal mythology. But what Sigma could uncover is even more frightening—something that will shake the very foundations of humanity.
Relativistic force-free models of the thermal X-ray emission in millisecond pulsars observed by NICER

description: Several important properties of rotation-powered millisecond pulsars (MSPs), such as their mass-radius ratio, equation of state and magnetic field topology, can be inferred from precise observations and modelling of their X-ray light curves. In the present study, we model the thermal X-ray signals originated in MSPs, all the way from numerically solving the surrounding magnetospheres up to the ray tracing of the emitted photons and the final computation of their light curves and spectra. Our modelled X-ray signals are then compared against a set of very accurate NICER observations of four target pulsars: PSR J0437-4715, PSR J1231-1411, PSR J2124-3358 and PSR J0030+0451. We find very good simultaneous fits for the light curve and spectral distribution in all these pulsars. The magnetosphere is solved by performing general relativistic force-free simulations of a rotating neutron star (NS) endowed with a simple centered dipolar magnetic field, for many different stellar compactness and pulsar misalignments. From these solutions, we derive an emissivity map over the surface of the star, which is based on the electric currents in the magnetosphere. In particular, the emission regions (ERs) are determined in this model by spacelike four-currents that reach the NS. We show that this assumption, together with the inclusion of the gravitational curvature on the force-free simulations, lead to non-standard ERs facing the closed-zone of the pulsar, in addition to other ERs within the polar caps. The combined X-ray signals from these two kinds of ERs (both antipodal) allow to approximate the non-trivial interpulses found in all the target MSPs light curves.
