description: The evenly-spaced modes of an electromagnetic resonator are coupled to each other by appropriate time-modulation, leading to dynamics analogous to those of particles hopping between different sites of a lattice. This substitution of a real spatial dimension of a lattice with a "synthetic'" dimension in frequency space greatly reduces the hardware complexity of an analog quantum simulator. Complex control and read-out of a highly multi-moded structure can thus be accomplished with very few physical control lines. We demonstrate this concept with microwave photons in a superconducting transmission line resonator by modulating the system parameters at frequencies near the resonator's free spectral range and observing propagation of photon wavepackets in time domain. The linear propagation dynamics are equivalent to a tight-binding model, which we probe by measuring scattering parameters between frequency sites. We extract an approximate tight-binding dispersion relation for the synthetic lattice and initialize photon wavepackets with well-defined quasimomenta and group velocities. As an example application of this platform in simulating a physical system, we demonstrate Bloch oscillations associated with a particle in a periodic potential and subject to a constant external field. The simulated field strongly affects the photon dynamics despite photons having zero charge. Our observation of photon dynamics along a synthetic frequency dimension generalizes immediately to topological photonics and single-photon power levels, and expands the range of physical systems addressable by quantum simulation.

description: We present an overview of the spectral variability of the peculiar F-type hypergiant Rho Cas, obtained from our long-term monitoring campaigns over the past 8.5 years with four spectrographs in the northern hemisphere. Between 2000 June and September an exceptional variability phase occurred when the V-brightness dimmed by about a full magnitude. The star recovered from this deep minimum by 2001 April. It is the third outburst of Rho Cas on record in the last century. We observe TiO absorption bands in high-resolution near-IR spectra obtained with the Utrecht Echelle Spectrograph during the summer of 2000. TiO formation in the outer atmosphere occurred before the deep brightness minimum. Atmospheric models reveal that the effective temperature decreases by at least 3000 K, and the TiO shell is driven supersonically with Mdot ~= 5.4 10^{-2} Msun/yr. Strong episodic mass loss and TiO have also been observed during the outbursts of 1945-47 and 1985-86. A detailed analysis of the exceptional outburst spectra is provided, by comparing with high-resolution optical spectra of the early M-type supergiants Mu Cep (Ia) and Betelgeuse (Iab). The outburst spectra indicate the formation of a low-temperature, optically thick circumstellar gas shell of 3 10^{-2} Msun during ~200 d, caused by dynamic instability of the upper atmosphere of this pulsating massive supergiant near the Eddington luminosity limit. We observe that the mass-loss rate during the outburst is of the same order of magnitude as has been proposed for the outbursts of Eta Carinae. We present calculations that correctly predict the outburst time-scale, whereby the shell ejection is driven by the release of hydrogen ionization-recombination energy.

description: The 2D half-filled Hubbard model is studied by a nonperturbative analytic theory of correlator projection. The original dynamical mean-field approximation (DMFA) is reproduced at the first-order projection and then improved by systematic inclusion of spatial correlations at higher orders. A geometrical frustration induces a first-order Mott transition surface with a finite-temperature critical end curve. Growth of antiferromagnetic correlations gives single-particle spectra strongly modified from DMFA with shadow bands and flat dispersions observed in high-T_c cuprates.

description: We utilize deep near-infrared survey data from the UltraVISTA fourth data release (DR4) and the VIDEO survey, in combination with overlapping optical and Spitzer data, to search for bright star-forming galaxies at $z \gtrsim 7.5$. Using a full photometric redshift fitting analysis applied to the $\sim 6\,{\rm deg}^2$ of imaging searched, we find 27 Lyman-break galaxies (LBGs), including 20 new sources, with best-fitting photometric redshifts in the range $7.4 < z < 9.1$. From this sample we derive the rest-frame UV luminosity function (LF) at $z = 8$ and $z = 9$ out to extremely bright UV magnitudes ($M_{\rm UV} \simeq -23$) for the first time. We find an excess in the number density of bright galaxies in comparison to the typically assumed Schechter functional form derived from fainter samples. Combined with previous studies at lower redshift, our results show that there is little evolution in the number density of very bright ($M_{\rm UV} \sim -23$) LBGs between $z \simeq 5$ and $z\simeq 9$. The tentative detection of an LBG with best-fit photometric redshift of $z = 10.9 \pm 1.0$ in our data is consistent with the derived evolution. We show that a double power-law fit with a brightening characteristic magnitude ($ΔM^*/Δz \simeq -0.5$) and a steadily steepening bright-end slope ($Δβ/Δz \simeq -0.5$) provides a good description of the $z > 5$ data over a wide range in absolute UV magnitude ($-23 < M_{\rm UV} < -17$). We postulate that the observed evolution can be explained by a lack of mass quenching at very high redshifts in combination with increasing dust obscuration within the first $\sim 1 \,{\rm Gyr}$ of galaxy evolution.

description: In this work, we present a numerical scheme to study the quasinormal modes of the time-dependent Vaidya black hole metric in asymptotically anti-de Sitter spacetime. The proposed algorithm is primarily based on a generalized matrix method for quasinormal modes. The main feature of the present approach is that the quasinormal frequency, as a function of time, is obtained by a generalized secular equation and therefore a satisfactory degree of precision is achieved. The implications of the results are discussed.

description: The course on quantitative research data explores the nuances of RDM, with particular emphasis on writing readme files, publishing and reusing research data and code, and using Git/GitHub for version control.  

The slides are part of the project "RDM curriculum Campus Luzern", which was partially funded by swissuniversities. Through this initiative, the University of Lucerne, in collaboration with the University of Applied Sciences and Arts (HSLU), the University of Teacher Education Lucerne (UTE, PH Luzern), and the Lucerne Central and University Library (ZHB) has enhanced its research data management (RDM) training for researchers. The program began with an introductory module that familiarized researchers with the fundamentals of RDM.  

Building on this foundation, advanced modules were developed to address specific needs: one focused on qualitative data and the other on quantitative data. Each module explored targeted thematic areas and incorporated keynotes, field reports from researchers, and interactive discussions. These modules, offered through the "Campus Luzern" initiative, were accessible to researchers from all participating institutions. 

The "Campus Luzern" promotes collaboration among the three HEIs in Lucerne to enhance doctoral education. Courses that meet a certain workload are awarded ECTS credits. This also allows the RDM modules to be accredited and officially recognized.

Anisotropic critical phenomena in parabolic geometries: the directed self-avoiding walk

Subjects: subject: Statistical Mechanics (cond-mat.stat-mech)
subject: FOS: Physical sciences

description: The critical behaviour of directed self-avoiding walks is studied on parabolic-like systems with a free boundary at x=\pm Ct^α. Using a scaling argument, 1/C is shown to be a marginal variable when α=ν_\perp/ν_\parallel=1/2, i.e., on a parabola. As a consequence the directed walk may display varying local exponents. Such a behaviour is indeed observed for restricted walks. This generalizes a result of Cardy showing that nonuniversal behaviour occurs at corners for isotropic systems.

Broadband X­ray Spectral Properties of NGC 55 ULX1
Creators: name: Jithesh, V.
Publisher: name: Zenodo
Year: 2022

description: We investigate the broadband X-ray spectral and temporal
 properties of ultra-luminous X-ray source (ULX) NGC 55 ULX1 using
 Swift, XMM-Newton and NuSTAR observations conducted during 2013-2021.
 In these observations, the source flux varies by a factor of ~ 5-6,
 and we identify the source mainly in the soft ultraluminous (SUL)
 state of ULXs. We fit the X-ray spectra with a two thermal component
 model consisting of a blackbody (for the soft component) and a disc
 (for the hard component), and the soft component dominates in these
 observations. The soft component in the SUL state shows properties
 similar to that of ultraluminous supersoft sources, for example, an
 anti-correlation between the characteristic radius and temperature of
 the blackbody component. In addition, we observe a positive
 correlation between the blackbody and inner disc temperatures when the
 X-ray spectra are fitted with the two-thermal component model. The
 source exhibits marginal evidence of X-ray flux dips in the Swift and
 XMM-Newton observations at different intensity levels. The observed
 spectral and temporal properties of the source can be explained by the
 supercritical radiatively driven outflow mechanism.
Convergence rates for the quantum central limit theorem

description: Various quantum analogues of the central limit theorem, which is one of the cornerstones of probability theory, are known in the literature. One such analogue, due to Cushen and Hudson, is of particular relevance for quantum optics. It implies that the state in any single output arm of an $n$-splitter, which is fed with $n$ copies of a centred state $ρ$ with finite second moments, converges to the Gaussian state with the same first and second moments as $ρ$. Here we exploit the phase space formalism to carry out a refined analysis of the rate of convergence in this quantum central limit theorem. For instance, we prove that the convergence takes place at a rate $\mathcal{O}\left(n^{-1/2}\right)$ in the Hilbert--Schmidt norm whenever the third moments of $ρ$ are finite. Trace norm or relative entropy bounds can be obtained by leveraging the energy boundedness of the state. Via analytical and numerical examples we show that our results are tight in many respects. An extension of our proof techniques to the non-i.i.d. setting is used to analyse a new model of a lossy optical fibre, where a given $m$-mode state enters a cascade of $n$ beam splitters of equal transmissivities $λ^{1/n}$ fed with an arbitrary (but fixed) environment state. Assuming that the latter has finite third moments, and ignoring unitaries, we show that the effective channel converges in diamond norm to a simple thermal attenuator, with a rate $\mathcal{O}\Big(n^{-\frac{1}{2(m+1)}}\Big)$. This allows us to establish bounds on the classical and quantum capacities of the cascade channel. Along the way, we derive several results that may be of independent interest. For example, we prove that any quantum characteristic function $χ_ρ$ is uniformly bounded by some $η_ρ<1$ outside of any neighbourhood of the origin; also, $η_ρ$ can be made to depend only on the energy of the state $ρ$.

description: Using data on Uruguayan firms (1997–2008) this paper explores whether the extent of informality in a sector affects a firm's investment decision either directly or indirectly through a credit availability channel. The results suggest that financial restrictions affect investment decisions: a one percentage point increase in overall credit growth translates into a one half percentage point increase in investment rates. It is also found that, although there is no direct effect of informality on the firm investment decision, there is an indirect effect through the borrowing channel.

A New Approach to Galaxy Morphology: I. Analysis of the Sloan Digital Sky Survey Early Data Release

Publisher: name: arXiv
Year: 2003
Subjects: subject: Astrophysics (astro-ph)

description: In this paper we present a new statistic for quantifying galaxy morphology based on measurements of the Gini coefficient of galaxy light distributions. This statistic is easy to measure and is commonly used in econometrics to measure how wealth is distributed in human populations. When applied to galaxy images, the Gini coefficient provides a quantitative measure of the inequality with which a galaxy's light is distributed amongst its constituent pixels. We measure the Gini coefficient of local galaxies in the Early Data Release of the Sloan Digital Sky Survey and demonstrate that this quantity is closely correlated with measurements of central concentration, but with significant scatter. This scatter is almost entirely due to variations in the mean surface brightness of galaxies. By exploring the distribution of galaxies in the three-dimensional parameter space defined by the Gini coefficient, central concentration, and mean surface brightness, we show that all nearby galaxies lie on a well-defined two-dimensional surface (a slightly warped plane) embedded within a three-dimensional parameter space. By associating each galaxy sample with the equation of this plane, we can encode the morphological composition of the entire SDSS g-band sample using the following three numbers: 22.451, 5.366, 7.010. The i-band sample is encoded as: 22.149, 5.373, and 7.627.

description: In this study we use survey expectations about a wide range of economic variables to forecast real activity. We propose an empirical approach to derive mathematical functional forms that link survey expectations to economic growth. Combining symbolic regression with genetic programming we generate two survey-based indicators: a perceptions index, using agents' assessments about the present, and an expectations index with their expectations about the future. In order to find the optimal combination of both indexes that best replicates the evolution of economic activity in each country we use a portfolio management procedure known as index tracking. By means of a generalized reduced gradient algorithm we derive the relative weights of both indexes. In most economies, the survey-based predictions generated with the composite indicator outperform the benchmark model for one-quarter ahead forecasts, although these improvements are only significant in Austria, Belgium and Portugal.

description: Heterostructures formed between two different van der Waals materials enable interactions and functionalities absent in each component. In this work we show that vicinity to an atomically thin WSe$_2$ sheet dramatically impacts the energies of the symmetry-broken low Landau levels of bilayer graphene, possibly due to screening. We present a systematic study of the magnetic field and electrical displacement field dependences of the Landau level gaps at filling factor $ν$ = 1, 2, 3, and compare to BN encapsulated pristine bilayer graphene. The exchange-dominated energy splitting between the N = 0 and 1 orbital wave functions is significantly enhanced, which leads to a modified phase diagram at filling factor $ν$ = 0 and larger energy gaps at $ν$ = 1 and 3 in WSe$_2$/bilayer graphene heterostructures. The exchange-enhanced spin gap at $ν$ = 2, on the other hand, is reduced by approximately two-fold. Our results demonstrate a possible way to engineer quantum Hall phenomena via van der Waals heterostructures.

description: This paper estimates redistribution and risk-sharing across provinces in Argentina during the 1995–2010 period as a result of the national budget. We find that the aggregate national budget (expenditure, transfers and their corresponding revenues) reduces differences in the per capita provincial Gross Geographic Product by 5% in the long term, and stabilizes such differences by 10%. The redistributive tool is national expenditure, while automatic intergovernmental transfers are almost neutral and tax revenues amplify regional disparities. The quantitative effects are somewhat modest in comparison with those achieved in developed countries. Regressive taxation is the key difference with developed countries.

In addition to the usual symmetry preserving even and odd states, nonlinearity introduces quite exotic symmetry breaking solutions - among them are trains of solitons with different number and sizes of density lumps in the two wells. We use the symmetry breaking localized solutions to form macroscopic quantum superpositions states and explore a simple model for the exponentially small tunneling splitting.

(Figs 7, 8, 19)
 Hypeugoa flavogrisea Leech, 1899, Transactions of the Entomological Society of London, 1899 (1): 190 (Type locality: [SW China, Sichuan, N of Kangding] “to the north of Ta-chien-lu... Western China ”).
 Type material examined. Holotype (by monotypy) (Fig. 7): male, “N. of Ta-chen-lu” / “ Hypeugoa flavogrisea type ♂. Leech.” /red ring “Type”label /“Leech Coll.1900-64.”/ QR-code label with unique number“ NHMUK010598613 ” (NHMUK).
 Additional material examined. CHINA: 1 male, [SE Gansu, Lixian, SW Qinling Mts] Kansu mer. or., Lihsien, Peilingschan mer., 3000m, July / Collection Daniel, gen. prep. No.: ZSM Arct. 2020-216 (prepared by Volynkin) (MWM/ ZSM).
 Diagnosis. The forewing length is 18–19.5 mm in males. The species (Figs 7, 8) superficially differs from S. orientalis (Figs 1–6) in the creamy head and collar (those are intensely suffused with grey scales in S. orientalis) and the markedly paler subbasal and subterminal areas of the forewing. The male genital capsule of S. flavogrisea (Fig. 19) differs from that of S. orientalis (Figs 17, 18) in the wider valva (the width to length ratio is 1:2.6 vs.1: 2.8 in S. orientalis) with the somewhat more convex costal margin, the less elongate harpe, the somewhat thinner medial crest of the valva and the more curved distal saccular process. The phallus of S. flavogrisea is somewhat more curved medially than that of S. orientalis. The vesica of S. flavogrisea is similar to that of S. orientalis but the distal diverticula are broader and separated from each other whereas in S. orientalis they originate from the common base.
Female unknown.
 Distribution. Known from western China (Sichuan and Gansu Provinces) (Leech 1899; Daniel 1951).

description: Fitch graphs $G=(X,E)$ are digraphs that are explained by $\{\emptyset, 1\}$-edge-labeled rooted trees $T$ with leaf set $X$: there is an arc $(x,y) \in E$ if and only if the unique path in $T$ that connects the last common ancestor $\mathrm{lca}(x,y)$ of $x$ and $y$ with $y$ contains at least one edge with label "1". In practice, Fitch graphs represent xenology relations, i.e., pairs of genes $x$ and $y$ for which a horizontal gene transfer happened along the path from $\mathrm{lca}(x,y)$ to $y$. In this contribution, we generalize the concept of Fitch graphs and consider trees $T$ that are equipped with edge-labeling $λ: E\to \mathcal{P}(M)$ that assigns to each edge a subset $M'\subseteq M$ of colors. Given such a tree, we can derive a map $\varepsilon_{(T,λ)}$ (or equivalently a set of not necessarily disjoint binary relations), such that $i\in \varepsilon_{(T,λ)}(x,y)$ (or equivalently $(x,y)\in R_i$) with $x,y\in X$, if and only if there is at least one edge with color $i$ from $\mathrm{lca}(x,y)$ to $y$. The central question considered here: Is a given map $\varepsilon$ a Fitch map, i.e., is there there an edge-labeled tree $(T,λ)$ with $\varepsilon_{(T,λ)} = \varepsilon$, and thus explains $\varepsilon$? Here, we provide a characterization of Fitch maps in terms of certain neighborhoods and forbidden submaps. Further restrictions of Fitch maps are considered. Moreover, we show that the least-resolved tree explaining a Fitch map is unique (up to isomorphism). In addition, we provide a polynomial-time algorithm to decide whether $\varepsilon$ is a Fitch map and, in the affirmative case, to construct the (up to isomorphism) unique least-resolved tree $(T^*,λ^*)$ that explains $\varepsilon$.

description: A long-standing problem of theoretical physics is the exceptionally small value of the cosmological constant $Λ\sim 10^{-120}$ measured in natural Planckian units. Here we derive this tiny number from a toroidal string cosmology based on closed strings. In this picture the dark energy arises from the correlation between momentum and winding modes that for short distances has an exponential fall-off with increasing values of the momenta.The freeze-out by the expansion of the background universe for these transplanckian modes may be interpreted as a frozen condensate of the closed-string modes in the three non-compactified spatial dimensions.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

description: The aim of this paper is to study relationships among "gauge integrals" (Henstock, Mc Shane, Birkhoff) and Pettis integral of multifunctions whose values are weakly compact and convex subsets of a general Banach space, not necessarily separable. For this purpose we prove the existence of variationally Henstock integrable selections for variationally Henstock integrable multifunctions. Using this and other known results concerning the existence of selections integrable in the same sense as the corresponding multifunctions, we obtain three decomposition theorems. As applications of such decompositions, we deduce characterizations of Henstock and ${\mathcal H}$ integrable multifunctions, together with an extension of a well-known theorem of Fremlin.

description: We calculate the energy and condensate fraction for a dense system of bosons interacting through an attractive short range interaction with positive s-wave scattering length $a$. At high densities, $n>>a^{-3}$, the energy per particle, chemical potential, and square of the sound speed are independent of the scattering length and proportional to $n^{2/3}$, as in Fermi systems.

Additive manufacturing has recently seen substantial growth, yet consistently producing high-quality parts remains a challenge. Recoating streaking is a common anomaly that impairs print quality. Several data-driven models for automatically detecting this anomaly have been proposed, each with varying effectiveness. However, comprehensive comparisons among them is lacking. Additionally, these models are often tailored to specific datasets. This research addresses this gap by implementing and comparing these anomaly detection models for recoating streaking in a reproducible way. We offer a clearer, more objective evaluation of their performance, strengths, and weaknesses. Furthermore, we propose an improvement to the Line Profiles detection model to broaden its applicability, and a novel preprocessing step was introduced to enhance the models' performances. These improvements established the Line Profiles model as the most efficient detection approach in our benchmark dataset.

description: We study the relationship between gerontocracy and aggregate economic performance in a simple model where growth is driven by human capital accumulation and productive government spending. We show that less patient élites display the tendency to underinvest in public education and productive government services, and thus are harmful for growth. The damage caused by gerontocracy is mainly due to the lack of long-term delayed return on investments, originated by the lower subjective discount factor. An empirical analysis using public investment in Information and Communication Technologies (ICT) is carried out to test theoretical predictions across different countries and different economic sectors. The econometric results confirm our main hypotheses.

description: We report a novel translation-regulatory function of G9a, a histone methyltransferase and well-understood transcriptional repressor, in promoting hyperinflammation and lymphopenia; two hallmarks of endotoxin tolerance (ET)-associated chronic inflammatory complications. Using multiple approaches, we demonstrate that G9a interacts with multiple translation regulators during ET, particularly the N6-methyladenosine (m6A) RNA methyltransferase METTL3, to co-upregulate expression of certain m6A-modified mRNAs that encode immune-checkpoint and anti-inflammatory proteins. Mechanistically, G9a promotes m6A methyltransferase activity of METTL3 at translational/post-translational level by regulating its expression, its methylation, and its cytosolic localization during ET. Additionally, from a broader view extended from the G9a-METTL3-m6A translation regulatory axis, our translatome proteomics approach identified numerous “G9a-translated” proteins that unite the networks associated with inflammation dysregulation, T cell dysfunction, and systemic cytokine response. In sum, we identified a previously unrecognized function of G9a in protein-specific translation that can be leveraged to treat ET-related chronic inflammatory diseases.
