description: We performed a validation exercise to recover the rotational modulation for 1,000 simulated PLATO light curves. We created a powerful simulation tool built upon the PLATO Solar-like Light-curve Simulator combining astrophysical (starspot rotation and evolution, planetary transits, oscillations, and granulations) and systematic instrumental effects. The simulated light curves follow specifications from the PLATO telescope in order to closely reproduce the expected raw data. We present a method of stitching and detrending to recover the original signal while also separating the rotational signal from the transit/eclipsing one. We find that a precise determination of rotation periods using this pre-processing pipeline is possible at every level of activity. From the stars with clear rotation determination, 92% of the values we recover are within the 10% confidence interval of the inputs.

description: The control of chlorophyll (Chl) synthesis in angiosperms depends on the light-operating enzyme protochlorophyllide oxidoreductase (POR). The interruption of Chl synthesis during darkness requires suppression of the synthesis of 5-aminolevulinic acid (ALA), the first precursor molecule specific for Chl synthesis. The inactivation of glutamyl-tRNA reductase (GluTR), the first enzyme in tetrapyrrole biosynthesis, accomplished the decreased ALA synthesis by the membrane-bound protein FLUORESCENT (FLU) and prevents overaccumulation of protochlorophyllide (Pchlide) in the dark. We set out to elucidate the molecular mechanism of FLU-mediated inhibition of ALA synthesis, and explored the role of each of the three structural domains of mature FLU, the transmembrane, coiled-coil and tetratricopeptide repeat (TPR) domains, in this process. Efforts to rescue the FLU knock-out mutant with truncated FLU peptides revealed that, on its own, the TPR domain is insufficient to inactivate GluTR, although tight binding of the TPR domain to GluTR was detected. A truncated FLU peptide consisting of transmembrane and TPR domains also failed to inactivate GluTR in the dark. Similarly, suppression of ALA synthesis could not be achieved by combining the coiled-coil and TPR domains. Interaction studies revealed that binding of GluTR and POR to FLU is essential for inhibiting ALA synthesis. These results imply that all three FLU domains are required for the repression of ALA synthesis, in order to avoid the overaccumulation of Pchlide in the dark. Only complete FLU ensures the formation of a membrane-bound ternary complex consisting at least of FLU, GluTR and POR to repress ALA synthesis.
Stellar Parameters Via Spectrum Synthesis Of APOGEE DR 16 H-band Spectra Of M Dwarf Stars

description: We present a method to derive stellar parameters for M dwarfs using high-resolution H-band spectra via spectrum synthesis using iSpec, Turbospectrum, MARCS models atmospheres, and a custom-made line list including over 1000000 water lines (Sarmento et al. 2021). The method was developed to provide reliable spectroscopic parameters from the spectra of current and future NIR high-resolution spectrographs. We derived the spectroscopic parameters (Teff, [M/H], log g) for a sample of 313 M dwarfs in the APOGEE DR16 and compared them to the ones obtained by ASPCAP and previous values derived from NIR and optical data.

description: This technote provides an overview of the Long-Term Pavement Performance (LTPP) Analysis-Ready datasets. The goal of the Long-Term Pavement Performance (LTPP) program is “to increase pavement life by the investigation of long-term performance. . . .” (FHWA 2015). One of the six objectives identified to support this goal was the establishment of a national pavement performance database. The LTPP program has been assembling a performance database since 1989, when data collection commenced. Today, the LTPP database is the world’s premier source of data and information on pavement performance, but using the database is not necessarily easy. Typically, the data are distributed across multiple tables, making some data elements difficult to mine. Also, multiple values for a given data element make knowing which values to use difficult. Additionally, the data may need further interpretation to present meaningful results. To address these challenges, the LTPP program undertook a process to generate analysis-ready datasets (ARDs) for all sections in the database so that data users did not have to spend effort wrangling data—i.e., finding, extracting, merging, and interpreting available data to develop an input dataset for analysis. These ARDs provide numerous benefits, such as simpler data handling, easier data analysis and data mining for trends, and descriptive data visualization.

description: Using multi-wavelength observations of SoHO/MDI, SOT-Hinode/blue-continuum (4504 Å), G-band (4305 Å), Ca II H (3968 Å) and TRACE 171 Å, we present the observational signature of highly twisted magnetic loop in AR 10960 during the period 04:43 UT-04:52 UT at 4 June, 2007. SOT-Hinode/blue-continuum (4504 Å) observations show that penumbral filaments of positive polarity sunspot have counter-clock wise twist, which may be caused by the clock-wise rotation of the spot umbrae. The coronal loop, whose one footpoint is anchored in this sunspot, shows strong right-handed twist in chromospheric SOT-Hinode/Ca II H (3968 Å) and coronal TRACE 171 Å\, images. The length and the radius of the loop are $L\sim$80 Mm and $a\sim$4.0 Mm respectively. The distance between neighboring turns of magnetic field lines (i.e. pitch) is estimated as $\approx$ 10 Mm. The total twist angle, $Φ\sim$12$π$ (estimated for the homogeneous distribution of the twist along the loop), is much larger than the Kruskal -Shafranov instability criterion. We detected clear double structure of the loop top during 04:47-04:51 UT on TRACE 171 Å\ images, which is consistent with simulated kink instability in curved coronal loops (T{ö}r{ö}k et al. 2004). We suggest, that the kink instability of this twisted magnetic loop triggered B5.0 class solar flare, which occurred between 04:40 UT and 04:51 UT in this active region.

Testing the Generalized Second Law in 1+1 dimensional Conformal Vacua: An Argument for the Causal Horizon

description: The anomalous conformal transformation law of the generalized entropy is found for dilaton gravity coupled to a 1+1 conformal matter sector with central charges $c = \tilde{c}$. (When $c \ne \tilde{c}$ the generalized entropy is not invariant under local Lorentz boosts.) It is shown that a certain second null derivative of the entropy, $S_\text{gen}" + (6/c)(S_\text{out}')^2$, is primary, and therefore retains its sign under a general conformal transformation. Consequently all conformal vacua have increasing entropy on causal horizons. Alternative definitions of the horizon, including apparent or dynamical horizons, can have decreasing entropy in any dimension $D \ge 2$. This indicates that the generalized second law should be defined using the causal horizon.

As a consequence we deduce that all nonhyperelliptic components of ℋ9(𝜇) are uniruled when 𝜇 is a positive partition of 16 and all nonhyperelliptic components of ℋ2𝑔(𝜇) are uniruled when 𝜇 is a positive partition of 4𝑔−4 and either 3⩽𝑔⩽5 or 𝑔=6 and 𝑙(𝜇)⩾4.
A direct method for solving the generalized sine-Gordon equation II

Publisher: name: arXiv

Subjects: subject: Exactly Solvable and Integrable Systems (nlin.SI)
subject: FOS: Physical sciences

description: The generalized sine-Gordon (sG) equation $u_{tx}=(1+ν\partial_x^2)\sin\,u$ was derived as an integrable generalization of the sG equation. In a previous paper (Matsuno Y 2010 J. Phys. A: Math. Theor. {\bf 43} 105204) which is referred to as I, we developed a systematic method for solving the generalized sG equation with $ν=-1$. Here, we address the equation with $ν=1$. By solving the equation analytically, we find that the structure of solutions differs substantially from that of the former equation. In particular, we show that the equation exhibits kink and breather solutions and does not admit multi-valued solutions like loop solitons as obtained in I. We also demonstrate that the equation reduces to the short pulse and sG equations in appropriate scaling limits. The limiting forms of the multisoliton solutions are also presented. Last, we provide a recipe for deriving an infinite number of conservation laws by using a novel Bäcklund transformation connecting solutions of the sG and generalized sG equations.

We introduce the tau-functions tau_pm(z) for the periodic Benjamin-Ono equation, construct two families of integrals of motion {M_1,M_2,cdots}, {overline{M}_1,overline{M}_2,cdots}, and calculate some examples of the bilinear equations using the Hamiltonian structure. We confirmed that some of the low lying bilinear equations agree with the ones obtained from a certain reduction of the 2D Toda hierarchy.

What has Canada caught, and how much is left? Reconstructing and assessing fisheries in three oceans
Creators: name: Schijns, Rebecca
Publisher: name: University of British Columbia
Year: 2020

description: Canada’s marine fisheries occur in three oceans, designated by Pacific, Arctic and Atlantic Exclusive Economic Zones (EEZs), where management bodies utilize catch records in order to make decisions regarding the future of their fisheries. However, current catch reporting systems and stock assessment processes are flawed, as catch records are missing key fishery components and assessments may use time series that do not represent the full scale of change. These shortcomings can directly impact the perception of healthy fisheries and influence future management decisions. This research provides a comprehensive catch record for all available marine populations in Canada’s three surrounding EEZs from 1950-2017 in order to estimate their current status and provide reference points that may be useful for managers to secure marine resources for the future. Catch reconstructions initially done by the Sea Around Us group and external collaborators, are refined and updated to 2017. Using reconstructed time series, the most recent ‘CMSY’ stock assessment method allows reference points to be estimated and reveals that the majority of Canadian fisheries need rebuilding. As well, ‘CMSY’ analyses are used to investigate shifting baseline effects on selected official stock assessments that exhibit shortened catch time series. Overall, this research contributes to improving scientific baselines in order to gain a better understanding of Canadian fisheries from a historical and managerial perspective.

description: A five-dimensional seesaw framework is analyzed with the lepton-number-violating propagator of bulk right-handed neutrinos. That can bypass summing up the effects of heavy Majorana particles whose masses and wavefunctions are not exactly known. The propagator method makes it easier to evaluate the seesaw-induced neutrino mass for various boundary conditions of bulk neutrinos and in a general background geometry, including the warped extra dimension. It is also found that the higher-dimensional seesaw gives a natural framework for the inverse seesaw suppression of low-energy neutrino masses.

description: In the area of networks, a common method to enforce a security policy expressed in a high-level language is based on an ad-hoc and manual rewriting process. We argue that it is possible to build a formal link between concrete and abstract terms, which can be dynamically computed from the environment data. In order to progressively introduce configuration data and then simplify the proof obligations, we use the B refinement process. We present a case study modeling a network monitor. This program, described by refinement following the layers of the TCP/IP suite protocol, has to warn for all observed events which do not respect the security policy. To design this model, we use the event-B method because it is suitable for modeling network concepts. This work has been done within the framework of the POTESTAT project, based on the research of network testing methods from a high-level security policy.
Modified catalyst layer interfaces for higher utilization and improved operational flexibility of low loading polymer electrolyte fuel cell catalyst layers
Creators: name: Daniel, Lius
Publisher: name: University of British Columbia
Year: 2020

description: Featuring low operational temperature and high-power density, polymer electrolyte membrane fuel cells (PEMFCs) have become the most researched and used fuel cell for the emerging automotive applications. To further promote the competitiveness of the fuel cell, improvement in operational flexibility to enable fuel cell to maintain its performance under various conditions is critical. The approach taken here was to modify the membrane electrode assembly (MEA) structure, particularly the interfaces of the cathode catalyst layer. Two interfaces were studied and modified, namely the membrane | cathode catalyst layer (CCL) and the CCL | microporous layer (MPL) interfaces. Firstly, the interface of the membrane and CCL was modified by addition of a thin, dense Pt layer in the membrane subsurface (<250 nm). This Pt layer was physically and electrochemically characterized. The application of this platinized membrane with a loading <20 µgPt/cm⁻² demonstrates a comparable performance to the baseline but improves the performance at low humidity conditions due to a better humidification of the membrane and catalyst layer. The performance benefits are also maintained during a longer humidity cycling test. This new platinized membrane structure also shows reduction in hydrogen crossover (up to 65%) with the loading studied (<80 µgPt/cm⁻²). Secondly, the interface of the CCL and MPL was modified by applying a modified MPL directly on the CCL. A new MEA architecture with a modified MPL consisting of 0.8 mgVC/cm⁻² reduces gaps at this interface, and hence reduces cell contact resistance by 31% and increases the limiting current density by about 10%. The modified MPL with 0.8 mg/cm⁻² Acetylene Black shows the highest performing MEA with ~37% maximum power density gain, while the optimum loading for VC-based MPL is ~0.4 - 0.8 mg/cm² yielding ~27% maximum power density gain at 100% RH. The loading of 0.8 mg/cm⁻² appears to be the threshold to enable the modified MPL to have performance benefits under low humidity. The long-term performance under low and high humidity showed that MEAs with additional modified MPL have a more stable and lower performance drop than for MEAs with a conventional MPL only.

description: We present a novel approach to the pricing of financial instruments in emission markets, for example, the EU ETS. The proposed structural model is positioned between existing complex full equilibrium models and pure reduced form models. Using an exogenously specified demand for a polluting good it gives a causal explanation for the accumulation of CO2 emissions and takes into account the feedback effect from the cost of carbon to the rate at which the market emits CO2. We derive a forward-backward stochastic differential equation for the price process of the allowance certificate and solve the associated semilinear partial differential equation numerically. We also show that derivatives written on the allowance certificate satisfy a linear partial differential equation. The model is extended to emission markets with multiple compliance periods and we analyse the impact different intertemporal connecting mechanisms, such as borrowing, banking and withdrawal, have on the allowance price.

The experimental results for the differential conductance as a function of bias, gate voltage, and external magnetic field are in agreement with our analysis of the tunneling rates and provide evidence of magnetic signatures in single-N@C60 devices arising from an antiferromagnetic exchange interaction between the C60 spin and the nitrogen spin.

We also give upper bounds on the rates of convergence for these local limit theorems and also for some other probability metrics. Our proofs are based on the Landau-Kolmogorov inequalities and new smoothing techniques.

To this end we explore the parameter space which is consistent with existing experimental constraints by means of a Markov Chain Monte Carlo analysis.

description: After a quiz to show the importance or respiratory health, I present the evolution of Breathing Games, from our first hackathon in Montreal in 2014 to the game jam held in Montreal, Geneva, Paris and Besançon. The three main games developed (two for children with asthma, one multiplayer where people can recount their experience by creating a game level) and controllers are then shortly presented. The evolution of perspective, from the self-management of disease to reflecting on social and political barriers to health is briefly mentioned. I then discuss common problems in organizing hackathons (information overload, waste of resources, loss of motivation), and illustrate it with the multiplication of unfinished open-source ventilation machines where one single modular design would in fact be needed. I present numbers of the covid hackathons held between March and June 2020, which mobilized 150000 people. The workforce mobilized for the five biggest events equaled 1568 full time employees… who developed 5771 competing, redundant projects instead of building on the collective wisdom. Finally, I present today's action to build health as commons, showing that solidarity-driven medical innovation is up to 99% cheaper. I propose a method to host large-scale events to empower citizens in building democratic, plural solutions within days. A six steps model to host such events is sketched.

Principi di conservazione

description: Il lavoro propone un percorso didattico, organizzato in più lezioni ed estendibile a più anni scolastici, che fa leva sull’importanza dei principi di conservazione di alcune grandezze fisiche fondamentali (in particolare l’energia). Ho previsto che il percorso parta con una classe di seconda, non necessariamente ad indirizzo scientifico, e faccia riferimento a quanto definito nel Piano degli Studi liceali come fisica dei fenomeni per poi ampliarsi toccando temi e formalismi propri della fisica dei modelli. A livello della classe di seconda ho portato in classe una serie di esperienze dimostrative che permettono di mettere in luce alcuni aspetti di dinamica dei fluidi (razzo di Bernoulli, wind-tube, tubi sonori, fontana di Erone). Tali esperienze in classe sono state sottoposte agli studenti prima che la parte teorica fosse affrontata per mezzo di lezioni in parte frontali e in parte dialogate e hanno avuto lo scopo di valorizzare le capacità di osservazione e sintesi degli allievi. L’obiettivo generale del percorso è quello di stimolare nella mente degli allievi un cambiamento nella visione che probabilmente hanno della fisica: dalla disciplina costituita da una collezione di formule in fondo mute a quella della scienza induttiva per eccellenza dove il saper fare (osservare, sintetizzare, ma anche imparare divertendosi) conta forse di più del sapere puro e semplice.

description: We discuss the predictivity of family symmetries for the soft supersymmetry breaking parameters in the framework of supergravity. We show that unknown details of the messenger sector and the supersymmetry breaking hidden sector enter into the soft parameters, making it difficult to obtain robust predictions. We find that there are specific choices of messenger fields which can improve the predictivity for the soft parameters.

Deep learning per la risonanza magnetica

Year: 2022

description: L’obiettivo principale di questo progetto, oltre al lato didattico, è l’implementazione di un modello di deep learning per la ricostruzione e il denoising di immagini derivanti da risonanza magnetica. I dataset a disposizione concernano immagini di cervelli e di cuori. La parte iniziale si indirizza verso la modellizzazione e la standardizzazione dei dati, per poi proseguire con l’inserimento manuale degli errori. Gli errori sono dati dalla variazione dei singoli pixel come conseguenza di una distribuzione normale e come risultato di rimozione di righe e singoli pixels dell’immagine. La metodologia applicata è inerente alle reti neurali, più precisamente agli autoencoder. Ne sono stati usati diversi, contenenti layer densi o convoluzionali, da più semplici a più complicati; all’utilizzo di reti convoluzionali i risultati sono stati più promettenti e portano a lavorare in quella direzione. Sono stati infatti trovati valori di MSE molto inferiori, 4 volte minori partendo da situazioni di rumore maggiore. Analizzando i risultati dei test si può affermare che l’MSE è proporzionale al valore del rumore, di conseguenza quando i disturbi aumentano si necessita di reti più potenti. Un dataset contenente immagini da 128x128 pixels varia da 10 righe rimosse con un MSE di 0.0045 fino a 20 righe rimosse con un MSE di 0.0093. Come proseguimento di questo progetto si valuterà la possibilità di continuare a lavorare con reti neurali con l’aggiunta di qualche regolarizzazione per diminuire ulteriormente il rumore. -- The main objective of this project, apart from the educational side, is the implementation of a deep learning model for the reconstruction and denoising of MRI-derived images. The available datasets concern images of brains and hearts. The initial part addresses the modelling and standardisation of the data, followed by the manual input of errors. Errors are given by the variation of individual pixels because of a normal distribution and because of removing rows and individual pixels of the image. The methodology applied is inherent to neural networks, more specifically autoencoders. Different ones were used, containing dense or convolutional layers, from the simplest to the most complicated; when using convolutional networks, the results were more promising and lead to work in that direction. In fact, much lower MSE values were found, 4 times lower starting from situations of higher noise. Analysing the test results, it can be stated that the MSE is proportional to the value of the noise, so that when the noise increases, more powerful networks are needed. A dataset containing images of 128x128 pixels ranges from 10 rows removed with an MSE of 0.0045 to 20 rows removed with an MSE of 0.0093. As a continuation of this project, we will consider continuing to work with neural networks with the addition of some regularisation to further reduce noise.

description: Firstly we discuss briefly three different algebras named as nonrelativistic (NR) conformal: Schroedinger, Galilean conformal and infinite algebra of local NR conformal isometries. Further we shall consider in some detail Galilean conformal algebra (GCA) obtained in the limit c equal to infinity from relativistic conformal algebra O(d+1,2) (d - number of space dimensions). Two different contraction limits providing GCA and some recently considered realizations will be briefly discussed. Finally by considering NR contraction of D=4 superconformal algebra the Galilei conformal superalgebra (GCSA) is obtained, in the formulation using complex Weyl supercharges.

description: In this article the degenerate warped products of singular semi-Riemannian manifolds are studied. They were used recently by the author to handle singularities occurring in General Relativity, in black holes and at the big-bang. One main result presented here is that a degenerate warped product of semi-regular semi-Riemannian manifolds with the warping function satisfying a certain condition is a semi-regular semi-Riemannian manifold. The connection and the Riemann curvature of the warped product are expressed in terms of those of the factor manifolds. Examples of singular semi-Riemannian manifolds which are semi-regular are constructed as warped products. Applications include cosmological models and black holes solutions with semi-regular singularities. Such singularities are compatible with a certain reformulation of the Einstein equation, which in addition holds at semi-regular singularities too.

description: Optical emission is detected from filaments around the central galaxies of clusters of galaxies. These filaments have lengths of tens of kiloparsecs. The emission is possibly due to heating caused by the dissipation of mechanical energy and by cosmic ray induced ionisation. CO millimeter and submillimeter line emissions as well as H$_{2}$ infrared emission originating in such filaments surrounding NGC~1275, the central galaxy of the Perseus cluster, have been detected. Our aim is to identify those molecular species, other than CO, that may emit detectable millimeter and submillimeter line features arising in these filaments, and to determine which of those species will produce emissions that might serve as diagnostics of the dissipation and cosmic ray induced ionisation. The time-dependent UCL photon-dominated region modelling code was used in the construction of steady-state models of molecular filamentary emission regions at appropriate pressures, for a range of dissipation and cosmic ray induced ionisation rates and incident radiation fields.HCO$^+$ and C$_2$H emissions will potentially provide information about the cosmic ray induced ionisation rates in the filaments. HCN and, in particular, CN are species with millimeter and submillimeter lines that remain abundant in the warmest regions containing molecules. Detections of the galaxy cluster filaments in HCO$^{+}$, C$_{2}$H, and CN emissions and further detections of them in HCN emissions would provide significant constraints on the dissipation and cosmic ray induced ionisation rates.
