description: We conduct a hard X-ray to radio multiwavelength spectral energy distribution (SED) decomposition for 57 local luminous and ultraluminous infrared galaxies (U/LIRGs) observed with Nuclear Spectroscopic Telescope Array and/or Swift/Burst Alert Telescope in GOALS (Armus et al. 2009) sample. We modify the latest SED-fitting code X-CIGALE by implementing the infrared (IR) CLUMPY model, allowing the multiwavelength study with the X-ray torus model (XCLUMPY) self-consistently. Adopting the torus parameters obtained by the X-ray fitting (Yamada et al. 2021), we estimate the properties of host galaxies, active galactic nucleus (AGN) tori, and polar dust. The star formation rates (SFRs) become larger with merger stage and most of them are above the main sequence. The SFRs are correlated with radio luminosity, indicating starburst emission is dominant in the radio band. Although polar-dust extinction is much smaller than torus extinction, the UV-to-IR (mainly IR) polar dust luminosities are $\sim$2 times larger than the torus ones. The polar-dust temperature decreases while the physical size, estimated by the temperature and dust sublimation radius, increases with AGN luminosity from a few tens of parsec (early mergers) to kiloparsec scales (late mergers), where the polar dust is likely the expanding (i.e., evolving) dusty outflows. The comparison between SFRs and intrinsic AGN luminosities suggests that the starbursts occur first and AGNs arise later, and overall their growth rates follow the simultaneous coevolution relation that can establish the local galaxy-SMBH mass relation. We confirm the coexistence of intense starbursts, AGNs, and large-scale outflows in late mergers, supporting a standard AGN feedback scenario.

description: The replication-dependent histone mRNAs, the only eukaryotic mRNAs that do not have poly(A) tails, are present only in S-phase cells. Coordinate posttranscriptional regulation of histone mRNAs is mediated by the stem-loop at the 3′ end of histone mRNAs. The protein that binds the 3′ end of histone mRNA, stem-loop binding protein (SLBP), is required for histone pre-mRNA processing and is involved in multiple aspects of histone mRNA metabolism. SLBP is also regulated during the cell cycle, accumulating as cells enter S phase and being rapidly degraded as cells exit S phase. Mutation of any residues in a TTP sequence (amino acids 60 to 62) or mutation of a consensus cyclin binding site (amino acids 99 to 104) stabilizes SLBP in G2 and mitosis. These two threonines are phosphorylated in late S phase, as determined by mass spectrometry (MS) of purified SLBP from late S-phase cells, triggering SLBP degradation. Cells that express a stable SLBP still degrade histone mRNA at the end of S phase, demonstrating that degradation of SLBP is not required for histone mRNA degradation. Nuclear extracts from G1 and G2 cells are deficient in histone pre-mRNA processing, which is restored by addition of recombinant SLBP, indicating that SLBP is the only cell cycle-regulated factor required for histone pre-mRNA processing.

description: In order to understand the puzzle of the free energy of an individual quark in QCD, we explicitly construct ensembles with quark numbers $N_V\neq 0\!\mod 3$, corresponding to non-zero triality in a finite subvolume $V$ on the lattice. We first illustrate the basic idea in an effective Polyakov-loop theory for the heavy-dense limit of QCD, and then extend the construction to full Lattice QCD, where the electric center flux through the surface of $V$ has to be fixed at all times to account for Gauss's law. This requires introducing discrete Fourier transforms over closed center-vortex sheets around the spatial volume $V$ between all subsequent time slices, and generalizes the construction of 't Hooft's electric fluxes in the purge gauge theory. We derive this same result from a dualization of the Wilson fermion action, and from the transfer matrix formulation with a local $\mathbb Z_3$-Gauss law to restrict the dynamics to sectors with the required center charge in $V$.

description: Two-photon emission of an electron in an electromagnetic plane wave of vanishing frequency is calculated. The unpolarised probability is split into a two-step process, which is shown to be exactly equal to an integration over polarised subprocesses, and a one-step process, which is found to be dominant over the formation length. The assumptions of neglecting spin and simultaneous emission, commonly used in numerical simulations, are discussed in light of these results.

Profiles of downwelling and upwelling irradiance were measured in a stratified, turbid reservoir, when Microcystis aeruginosa formed a significant proportion of the phytoplankton community. The attenuation coefficient (Kd) was c. 2.1 m-1 and the reflectance (R) c. 0.03. Application of Kirk's simulation model relating apparent and inherent optical properties enabled calculation of coefficients of absorption (a; 1.3-1.6 m-') and scattering (6; 5-7 m-1). The asymptotic diffuse backscattering coefficient (0.2 m-1) was derived from the relationship b′b = 3.6 RaKd, a slight modification of Kirk's original equation. Turbidity measurements supported the general rule that nephelometric turbidity was numerically equivalent to the scattering coefficient.There was good agreement between the measured light profile and one reconstructed from inherent optical properties using the relationship between Kd, a and b.The optical properties of cells and colonies of Microcystis were investigated before and after the collapse of gas vacuoles. The Chla-specific absorption coefficient for cells (0.0138 m2 mg,-1 Chla) was higher than for colonies (0.0106 m2 mg,-1 Chla) at a depth equivalent to 0.2 m. Both coefficients decreased with increasing depth as the spectral composition changed. The Chla-specific scattering coefficient for vacuolate cells (0.14 m2 mg,-1 Chla) was greater than for colonies (0.11 m2 mg,-1 Chla), and a similar correspondence occurred for non-vacuolate cells and colonies (0.029 and 0.020 m2 mg,-1 Chla respectively). These measurements illustrate the package effect and also that c. 80% of light scattering is due to gas vacuoles. The relationship between pressure-sensitive turbidity and gas-vacuole volume suggested that 1 gL mL-1 was equivalent to a turbidity of 2 NTU. These optical characteristics, combined with the buoyant nature of Microcystis, suggest that it is a canopy species.

description: Databases contain information about which relationships do and do not hold among entities. To make this information accessible for statistical analysis requires computing sufficient statistics that combine information from different database tables. Such statistics may involve any number of {\em positive and negative} relationships. With a naive enumeration approach, computing sufficient statistics for negative relationships is feasible only for small databases. We solve this problem with a new dynamic programming algorithm that performs a virtual join, where the requisite counts are computed without materializing join tables. Contingency table algebra is a new extension of relational algebra, that facilitates the efficient implementation of this Möbius virtual join operation. The Möbius Join scales to large datasets (over 1M tuples) with complex schemas. Empirical evaluation with seven benchmark datasets showed that information about the presence and absence of links can be exploited in feature selection, association rule mining, and Bayesian network learning.

description: The novel data analysis challenges posed by the Laser Interferometer Space Antenna (LISA) arise from the overwhelmingly large number of astrophysical sources in the measurement band and the density with which they are found in the data. Robust detection and characterization of the numerous gravitational wave sources in LISA data can not be done sequentially, but rather through a simultaneous global fit of a data model containing the full suite of astrophysical and instrumental features present in the data. While previous analyses have focused on individual source types in isolation, here we present the first demonstration of a LISA global fit analysis containing combined astrophysical populations. The prototype pipeline uses a blocked Metropolis Hastings algorithm to alternatingly fit to a population of ultra compact galactic binaries, known ``verification binaries'' already identified by electromagnetic observations, a population of massive black hole mergers, and an instrument noise model. The Global LISA Analysis Software Suite (GLASS) is assembled from independently developed samplers for the different model components. The modular design enables flexibility to future development by defining standard interfaces for adding new, or updating additional, components to the global fit without being overly prescriptive for how those modules must be internally designed. The GLASS pipeline is demonstrated on data simulated for the LISA Data Challenge 2b. Results of the analysis and a road-map for continued development are described in detail.

description: Recent discoveries of superconductivity in hydrogen-rich compounds stabilized by high pressures have shown that a critical temperature of superconductivity Tc can reach near room temperature values. The current studies focus on the search for new superconductors with higher Tcs to understand the ultimate limit of conventional superconductivity, and high-Tc superconductors at lower pressures. However, high pressure conditions put serious limitations on experimental studies. Electrical transport measurements have long been the primary experimental technique for reliable detection of superconductivity at high pressures, whereas magnetic susceptibility measurements continue to be a challenge. Here, we dramatically changed the protocol of magnetic measurements to probe the trapped magnetic flux. We tested this technique on samples of H3S and LaH10 and propose it for a routine examination of superconductivity at high pressures. Using the temperature- and magnetic field dependences of the trapped flux we estimated Tc ~195 K, a lower critical field ~0.36 T, an irreversibility field ~1.7 T, a full penetration field ~8.8 T, the London penetration depth ~37 nm, and critical current densities jc(T) in H3S at ~155 GPa in a wide temperature range. The trapped flux method is found to be sensitive to a particular phase in a mixture of superconducting phases: concomitant phases of sulfur and hydrogen-depleted LaHx were detected. In contrast to the Meissner state occurring at low external magnetic fields, a magnetic response from the trapped flux at zero applied magnetic field is in tens times stronger and is not contaminated by the magnetic background of a bulky diamond anvil cell. This technique can be a powerful tool for the screening of new superconducting materials, the study of multiphase, contaminated samples, or samples with a low superconducting fraction at ambient pressure too.

Les cours s’y rapportant font l’objet d’un choix, autrement dit d’un module à option. La médecine conventionnelle a fait ses preuves. Il est certain qu’à ce jour le monde de la santé ne cesse d’évoluer, d’en étonner plus d’un. De plus, il connaît d’énormes différences selon les pays. Pourtant, la majorité des médecines complémentaires sont méconnues autant des patients que des professionnels de la santé. Il semblerait que la progression du domaine de la santé ne rime pas avec intégration des thérapies complémentaires. Il s’agit là de notre point de vue, de discussions et de partages d’opinions sur le sujet. Nombreuses étaient nos questions y relatives : bien que l’efficacité de certaines d’entre elles ait été prouvée, pourquoi les thérapies complémentaires ne prennent-elles pas une plus grande place au sein du monde de la santé ? L’hypnose, en particulier, fait l’objet de nombreuses remarques. Dernièrement, des émissions ont abordé ce sujet, mettant en avant son efficacité, son utilisation lors d’opérations chirurgicales. Mais ce qui est dit résume-t-il correctement la fonction de l’hypnose ? Comment la population perçoit-elle cette intervention ? Quelles sont ses représentations ? L’infirmière peutelle réellement proposer cette approche aux patients ? Ainsi, nous en sommes venues à étudier cette thématique à travers la recherche scientifique, afin de nous positionner et d’enrichir notre pratique professionnelle. Le cheminement qui a suivi, a permis l’identification de la population cible ainsi que notre question de recherche. Ainsi, ce projet s’est transformé en une revue de littérature dans le cadre de notre dernière année de formation.

Organic matter degradation and nutrient regeneration in Australian freshwaters: I. Methods for exoenzyme assays in turbid aquatic environments
Creators: name: Boon, Paul I

Year: 2023

description: Murray-Darling Freshwater Research Centre

MDFRC item.

A method was developed using p-nitrophenol and p-nitroaniline derivatives to measure exoenzyme activity in turbid waters, as an indicator of biodegradation. Maximum activity occurred at or above 40 C. The response to variations in pH was complex, with some systems showing no clear optimum but others showing an optimum at either pH 7.5 or pH 9.0-10. Only 25% of the enzyme system-site combinations generated linear Line-weaver-Burke plots, indicating that many exoenzyme systems were active simultaneously in the degradation of organic detritus. The maximum rate of activity occurred with aminopeptidase (up to 107 micromol/L/d), followed by alkaline phosphatase (up to 42 micromol/L/d). There was little lipase or alpha-D glucosidase activity in the any water body, except in a highly-eutrophied lagoon. Rates were consistently higher in billabongs than in rivers, and most activity was associated with particles rather than being free in the water column.

description: We calculate the relativistic six-meson scattering amplitude at low energy within the framework of QCD-like theories with $n$ degenerate quark flavors at next-to-leading order in the chiral counting. We discuss the cases of complex, real and pseudo-real representations, i.e. with global symmetry and breaking patterns $\text{SU}(n)\times\text{SU}(n)/\text{SU}(n)$ (extending the QCD case), $\text{SU}(2n)/\text{SO}(2n)$, and $\text{SU}(2n)/\text{Sp}(2n)$. In case of the one-particle-irreducible part, we obtain analytical expressions in terms of 10 six-meson subamplitudes based on the flavor and group structures. We extend on our previous results obtained within the framework of the $\text{O}(N+1)/\text{O}(N)$ non-linear sigma model, with $N$ being the number of meson flavors. This work allows for studying a number of properties of six-particle amplitudes at one-loop level.

A unifying poset perspective on alternating sign matrices, plane partitions, Catalan objects, tournaments, and tableaux

description: Alternating sign matrices (ASMs) are square matrices with entries 0, 1, or -1 whose rows and columns sum to 1 and whose nonzero entries alternate in sign. We present a unifying perspective on ASMs and other combinatorial objects by studying a certain tetrahedral poset and its subposets. We prove the order ideals of these subposets are in bijection with a variety of interesting combinatorial objects, including ASMs, totally symmetric self-complementary plane partitions (TSSCPPs), staircase shaped semistandard Young tableaux, Catalan objects, tournaments, and totally symmetric plane partitions. We prove product formulas counting these order ideals and give the rank generating function of some of the corresponding lattices of order ideals. We also prove an expansion of the tournament generating function as a sum over TSSCPPs. This result is analogous to a result of Robbins and Rumsey expanding the tournament generating function as a sum over alternating sign matrices.

description: L'articolo esamina il processo di rielaborazione musicale attraverso il confronto tra il madrigale Itene o miei sospiri di Carlo Gesualdo e la composizione In Amoroso canto di Gianvincenzo Cresta. Viene sottolineato come la musica, liberata dalle contingenze storiche, possa risuonare con nuove significanze nel presente. Molti compositori come Stravinskij, Sciarrino e Mantovani hanno risco perto Gesualdo, dialogando con la sua musica. Il compositore Gianvincenzo Cresta, in particolare, combina musica antica e sperimentale per creare opere che uniscono passato e presente. Nel suo lavoro, si ispira al madrigale di Gesualdo. La presente analisi si concentra su come le sezioni del madrigale vengono elaborate, con particolare attenzione alle dimensioni temporali, perché per il compositore la musica è energia che si muove nel tempo. Dall’analisi si nota come Cresta non si limita a citare o parafrasare l'originale, ma ricalca la struttura temporale del madrigale, espandendo e reinterpretando le sue caratteristiche energetiche, questo fa sì che la sua composizione diventi qualcosa di “altro”. Questo processo crea una musica che, pur richiamando il passato, si presenta come nuova e originale. In conclusione l'articolo mette in evidenza un concetto che è alla base della poetica di Cresta, ossia che la musica è "la forma del tempo".
description: The article examines the process of musical reworking through a comparison of Carlo Gesualdo's madrigal Itene o miei sospiri and Gianvincenzo Cresta's composition In Amoroso canto. It is emphasized how music, freed from historical contingencies, can resonate with new meanings in the present. Many composers such as Stravinsky, Sciarrino and Mantovani have rediscovered Gesualdo, dialoguing with his music. Composer Gianvincenzo Cresta, in particular, combines early and experimental music to create works that unite past and present. In his work, he draws inspiration from Gesualdo's madrigal. This analysis focuses on how sections of the madrigal are processed, with particular attention to temporal dimensions, because for the composer, music is energy moving through time. The analysis shows that Cresta does not merely quote or paraphrase the original; he traces the temporal structure of the madrigal, expanding and reinterpreting its energetic characteristics, making his composition something "other." This process creates music that, while recalling the past, appears new and original. In conclusion, the article highlights a concept that lies at the heart of Cresta's poetics: music is “the form of time.”
Polymerase Mu Is a DNA-Directed DNA/RNA Polymerase

description: DNA polymerases are defined as such because they use deoxynucleotides instead of ribonucleotides with high specificity. We show here that polymerase mu (pol μ), implicated in the nonhomologous end-joining pathway for repair of DNA double-strand breaks, incorporates both ribonucleotides and deoxynucleotides in a template-directed manner. pol μ has an approximately 1,000-fold-reduced ability to discriminate against ribonucleotides compared to that of the related pol β, although pol μ's substrate specificity is similar to that of pol β in most other respects. Moreover, pol μ more frequently incorporates ribonucleotides when presented with nucleotide concentrations that approximate cellular pools. We therefore addressed the impact of ribonucleotide incorporation on the activities of factors required for double-strand break repair by nonhomologous end joining. We determined that the ligase required for this pathway readily joined strand breaks with terminal ribonucleotides. Most significantly, pol μ frequently introduced ribonucleotides into the repair junctions of an in vitro nonhomologous end-joining reaction, an activity that would be expected to have important consequences in the context of cellular double-strand break repair.

description: We review a large body of literature for concentrations of halogens in chondrites and stellar halogen data used for solar system abundances (i.e., representative abundances of the solar system at the time of its formation) and associated analytical problems. Claims of lower solar system chlorine, bromine and iodine abundances from recent analyses of CI-chondrites are untenable because of incompatibility of such low values with nuclear abundance systematics and measurements of halogens in the sun and other stars. We suspect analytical problems associated with these peculiar rock types caused lower analytical results in several studies. Mass concentrations in CI-chondrites are F=92+-20 ppm, Cl=717+-110 ppm, Br=3.77+-0.90 ppm, and I=0.77+-0.31 ppm, and abundances normalized to N(Si) =10^6 atoms are N(F)=1270+-270, N(Cl)=5290+-810, N(Br)=12.3+-2.9, and N(I)=1.59+-0.64. Meteoritic values scaled to present-day photospheric abundances with log N(H)=12 are A(F)=4.61+-0.09, A(Cl)=5.23+-0.06, A(Br)=2.60+-0.09, and A(I)=1.71+-0.15. These recommended present-day solar system abundances compare to the sunspot values of N(F)=776+-260, A(F)=4.40+-0.25, and N(Cl)=5500+-810, A(Cl)=5.25+-0.12 and are consistent with F and Cl abundance ratios in other stars and other astronomical environments. The chlorine abundance of 776+-21 ppm by Yokoyama et al. (2022) for the CI-chondrite-like asteroid Ryugu is consistent with the chlorine abundance evaluated for CI-chondrites here. Updated equilibrium 50% condensation temperatures from our previous work (Lodders 2003, Fegley & Schaefer 2010, Fegley & Lodders 2018) considering solid-solution and kinetic inhibition effects are 713K (F), 427K (Cl), 392K (Br) and 312K (I) at 10^-4 bar total pressure. Condensation temperatures computed with lower halogen abundances do not represent the correct condensation temperatures from a solar composition gas. (abridged)

description: The kaon sector is characterised by several processes which are under active investigation across different experiments. In this work, we present the global picture that emerges from a study of the different decay modes. We begin by revisiting the theoretical component of these decays and providing up-to-date predictions of the Standard Model as well as the corresponding uncertainties. Several new features emerge, in particular for $K_{S,L}\to μ\barμ$, and are presented in considerable detail. This offers an ideal platform for extracting the parameter space supported by the existing data. Motivated by possible lepton flavour universality violation in $B$ decays, we investigate such Beyond the Standard Model effects also in rare kaon decays. Without loss of generality, our primary analyses correspond to the paradigm where the Wilson coefficients for operators involving tau leptons are chosen to be equal to that involving the muon, i.e. $δC^τ=δC^μ$. We conclude by presenting the possible picture that can be achieved towards the end of the run of data accumulation in the planned experiments. This includes assumptions on possible sensitivity goals that the experiments can aim to achieve, in order to extract the kind of physics highlighted in this paper.

description: The gene encoding p53 mediates a major tumor suppression pathway that is frequently altered in human cancers. p53 function is kept at a low level during normal cell growth and is activated in response to various cellular stresses. The MDM2 oncoprotein plays a key role in negatively regulating p53 activity by either direct repression of p53 transactivation activity in the nucleus or promotion of p53 degradation in the cytoplasm. DNA damage and oncogenic insults, the two best-characterized p53-dependent checkpoint pathways, both activate p53 through inhibition of MDM2. Here we report that the human homologue of MDM2, HDM2, binds to ribosomal protein L11. L11 binds a central region in HDM2 that is distinct from the ARF binding site. We show that the functional consequence of L11-HDM2 association, like that with ARF, results in the prevention of HDM2-mediated p53 ubiquitination and degradation, subsequently restoring p53-mediated transactivation, accumulating p21 protein levels, and inducing a p53-dependent cell cycle arrest by canceling the inhibitory function of HDM2. Interference with ribosomal biogenesis by a low concentration of actinomycin D is associated with an increased L11-HDM2 interaction and subsequent p53 stabilization. We suggest that L11 functions as a negative regulator of HDM2 and that there might exist in vivo an L11-HDM2-p53 pathway for monitoring ribosomal integrity.

description: Inosine 5′-monophosphate dehydrogenase (IMPDH) is the critical, rate-limiting enzyme in the de novo biosynthesis pathway for guanine nucleotides. Two separate isoenzymes, designated IMPDH types I and II, contribute to IMPDH activity. An additional pathway salvages guanine through the activity of hypoxanthine-guanine phosphoribosyltransferase (HPRT) to supply the cell with guanine nucleotides. In order to better understand the relative contributions of IMPDH types I and II and HPRT to normal biological function, a mouse deficient in IMPDH type I was generated by standard gene-targeting techniques and bred to mice deficient in HPRT or heterozygous for IMPDH type II. T-cell activation in response to anti-CD3 plus anti-CD28 antibodies was significantly impaired in both single- and double-knockout mice, whereas a more general inhibition of proliferation in response to other T- and B-cell mitogens was observed only in mice deficient in both enzymes. In addition, IMPDH type I−/− HPRT−/0 splenocytes showed reduced interleukin-4 production and impaired cytolytic activity after antibody activation, indicating an important role for guanine salvage in supplementing the de novo synthesis of guanine nucleotides. We conclude that both IMPDH and HPRT activities contribute to normal T-lymphocyte activation and function.

description: The objective of this research was to understand the co-dependent relationship of mangrove ecosystems, public mangrove discourses and the human use of mangrove areas. Research questions were: How have mangroves been made sense of around the Gulf of Guayaquil from the 19th century until today, and how does this guide the use of mangrove areas today? Mangroves were studied from the perspective of Social and Discursive Constructivism, arguing that mangroves are being made sense of by humans by relating to them socially and discursively. The Sociology of Knowledge Approach to Discourse (SKAD) by Reiner Keller served as methodological framework: Methods were interdisciplinary, and span from ethnographic methods (participant observation, interviews) to participatory mapping and archival research. The outcomes of the research show that some cultural groups living in the research area were historically highly underrepresented in political knowledge production and in the governance of mangroves. With the advent of a shrimp industry in the mangroves in the late 1980s globalized discourses of commodification, conservation and development entered intensively into the area, producing hybrid zones of knowledge invasion and negotiation resulting in a very visible Mangrove Culture today: Structural underrepresentation and socio-economic conditions caused severe marginalization of historically already marginalized and excluded groups on the one hand. On the other hand, innovative adaption strategies submerged, showing how people can make a living in and can make innovative meanings of mangroves close to the city. Understanding the impact of intensive knowledge influx in an area and the result it has for natural resource governance helps decision-makers and stakeholders to analyse, guide and soften discourses and knowledge. It leads actions for a more sustainable co-living of mangroves and humans, at the same time increasing visibility of and thus empower underrepresented groups.

The supply of oxygen to respiring shoot tissue was investigated for three submerged macrophytes (Potamogeton crispus L., Egeria densa Planch, and Myriophyllum triphyllum Orchard). For all species, the response of oxygen uptake rates to the external O2 concentration was a rectangular hyperbola over the range 0–5.0 × 10−3m3 m−3. However, the response pattern for material with water-infiltrated lacunar airspaces was non-hyperbolic over this range. The change in response was interpreted as an increased substrate (O2) limitation, resulting from lower radial diffusion rates within the infiltrated material. Neither the uninfiltrated nor the infiltrated responses obeyed the linear and logarithmic formulae of the type observed for submerged macrophytes by earlier authors. These results suggest that the responses observed are affected by factors such as water velocity, internal restrictions to diffusion and the range of oxygen tensions investigated. Therefore, it is unlikely that one response formula can adequately account for the effects of oxygen concentration on submerged macrophyte oxygen uptake. The lacunar airspaces also represent a possible oxygen source for dark respiration. The consumption of oxygen from the airspaces was investigated by displacing the gas from the lacunae and measuring the subsequent increase in the rate of oxygen assimilation from the external liquid. Approximately 30% of the oxygen consumed by E. densa and P. crispus, and more than 40% of that consumed by M. triphyllum, was derived from the lacunar system. This O2 supply is a consequence of the higher oxygen concentration in the lacunae than in the external medium, due to the low solubility of oxygen in water. Storage of photosynthetically-produced oxygen in the lacunae could not be identified during a light/dark transient, due to rate changes caused by the effects of light on the respiratory metabolism. However, O2 partial pressure gradients artificially set up between the lacunae and water equilibrated within an hour, suggesting that excess oxygen would be lost to the water within this time.

description: We report the all-optical production of Bose Einstein condensates (BEC) of $^{39}$K atoms. We directly load $3 \times 10^{7}$ atoms in a large volume optical dipole trap from gray molasses on the D1 transition. We then apply a small magnetic quadrupole field to polarize the sample before transferring the atoms in a tightly confining optical trap. Evaporative cooling is finally performed close to a Feshbach resonance to enhance the scattering length. Our setup allows to cross the BEC threshold with $3 \times 10^5$ atoms every 7s. As an illustration of the interest of the tunability of the interactions we study the expansion of Bose-Einstein condensates in the 1D to 3D crossover.

description: In this work, thick branes in Rastall gravity are investigated. Three types of maximally symmetric thick brane models are constructed and the linear tensor perturbation is analyzed. In the flat brane model, the tensor modes of the perturbation are either unstable or nonlocalizable for a nonvanishing Rastall parameter. In the de Sitter brane model, only the ground state of the tensor mode is localized. In the anti-de Sitter brane model, the number of the bound tensor states is infinity. For both the de Sitter and anti-de Sitter brane models, the condition of stability for the Rastall parameter is obtained.

description: The development of the mature insect trachea requires a complex series of cellular events, including tracheal cell specification, cell migration, tubule branching, and tubule fusion. Here we describe the identification of the Drosophila melanogaster dysfusion gene, which encodes a novel basic helix-loop-helix (bHLH)-PAS protein conserved between Caenorhabditis elegans, insects, and humans, and controls tracheal fusion events. The Dysfusion protein functions as a heterodimer with the Tango bHLH-PAS protein in vivo to form a putative DNA-binding complex. The dysfusion gene is expressed in a variety of embryonic cell types, including tracheal-fusion, leading-edge, foregut atrium cells, nervous system, hindgut, and anal pad cells. RNAi experiments indicate that dysfusion is required for dorsal branch, lateral trunk, and ganglionic branch fusion but not for fusion of the dorsal trunk. The escargot gene, which is also expressed in fusion cells and is required for tracheal fusion, precedes dysfusion expression. Analysis of escargot mutants indicates a complex pattern of dysfusion regulation, such that dysfusion expression is dependent on escargot in the dorsal and ganglionic branches but not the dorsal trunk. Early in tracheal development, the Trachealess bHLH-PAS protein is present at uniformly high levels in all tracheal cells, but since the levels of Dysfusion rise in wild-type fusion cells, the levels of Trachealess in fusion cells decline. The downregulation of Trachealess is dependent on dysfusion function. These results suggest the possibility that competitive interactions between basic helix-loop-helix-PAS proteins (Dysfusion, Trachealess, and possibly Similar) may be important for the proper development of the trachea.

description: Recent contrastive learning methods achieved state-of-the-art in low label regimes. However, the training requires large batch sizes and heavy augmentations to create multiple views of an image. With non-contrastive methods, the negatives are implicitly incorporated in the loss, allowing different images and modalities as pairs. Although the meta-information (i.e., age, sex) in medical imaging is abundant, the annotations are noisy and prone to class imbalance. In this work, we exploited already existing temporal information (different visits from a patient) in a longitudinal optical coherence tomography (OCT) dataset using temporally informed non-contrastive loss (TINC) without increasing complexity and need for negative pairs. Moreover, our novel pair-forming scheme can avoid heavy augmentations and implicitly incorporates the temporal information in the pairs. Finally, these representations learned from the pretraining are more successful in predicting disease progression where the temporal information is crucial for the downstream task. More specifically, our model outperforms existing models in predicting the risk of conversion within a time frame from intermediate age-related macular degeneration (AMD) to the late wet-AMD stage.

description: Partendo dalla complessa relazione tra pensiero poetico e riflessione filosofica, passando per un’accezione immaginale e filosofico-religiosa del concetto di simbolo, il saggio mette in relazione la pratica poetica con la fenomenologia estetica del simbolo. Alcune figure poetiche di matrice Romantica e medio-novecentesca, come Hölderlin, Rilke, Bonnefoy e Luzi, vengono interrogate alla luce della concezione tautegorica del simbolo. Il concetto di “tautegoria”, proveniente dalla riflessione sull’immagine di Corbin, insieme ad altre esperienze di pensiero afferenti alla moderna cultura visuale, mette al centro l’identità di simbolo e simboleggiato, di segno e referente, creando una frattura con i concetti di allegoria e di rappresentazione astratta. In questa serie di riflessioni si ipotizza un legame tra iniziazione religiosa e pensiero poetico. Poesia e simbolo, intesi come movimenti attivi dello spirito tesi alla resa presente del reale, si trovano uniti, in questa prospettiva, contro l’astrazione concettuale e rappresentativa del pensiero e del linguaggio.
description: Starting from the complex relationship between poetic thought and philosophical reflection, moving through an imaginal and philosophical-religious interpretation of the concept of symbol, the essay relates poetic practice to the aesthetic phenomenology of the symbol. Some poetic figures of the Romantic and mid-20th century matrix, such as Hölderlin, Rilke, Bonnefoy and Luzi, are interrogated in the light of the tautegorical conception of the symbol. The concept of "tautegoria", originating from Corbin's reflection on the image, together with other experiences of thought pertaining to modern visual culture, focuses on the identity of symbol and symbolised, sign and referent, creating a break with the concepts of allegory and abstract representation. In this series of reflections, a link is hypothesised between religious initiation and poetic thought. Poetry and symbol, understood as active movements of the spirit aimed at the present rendering of the real, find themselves united in this perspective against the conceptual and representational abstraction of thought and language.

description: We study minimizers of non-autonomous functionals \begin{align*} \inf_u \int_Ωφ(x,|\nabla u|) \, dx \end{align*} when $φ$ has generalized Orlicz growth. We consider the case where the upper growth rate of $φ$ is unbounded and prove the Harnack inequality for minimizers. Our technique is based on "truncating" the function $φ$ to approximate the minimizer and Harnack estimates with uniform constants via a Bloch estimate for the approximating minimizers.
