description: The bad metal behavior in the normal state of the iron-based superconductors suggests an intimate connection between the superconductivity and a proximity to a Mott transition. At the same time, there is strong evidence for the multi-orbital nature of the electronic excitations. It is then important to understand the orbital-dependent effects of electron correlations. In this paper we review the recent theoretical progresses on the metal-to-insulator transition in multiorbital models for the iron-based superconductors. These include studies of models that contain at least the 3d xy and 3d xz/yz models, using a slave-spin technique. For commensurate filling corresponding to that of the parent iron pnictides and chalcogenideds, a Mott transition generally exists in all these models. Near the Mott transition, a strongly correlated metal exhibiting bad metal features and strong orbital selectivity is stabilized due to the interplay of Hund's coupling and orbital-degeneracy breaking. Particularly for the alkaline iron selenides, the ordered vacancies effectively reduce the kinetic energy, thereby pushing the system further into the Mott-insulating regime; in the metallic state, there exists an orbital-selective Mott phase in which the iron 3d xy orbital is Mott localized while the other 3d orbitals are still itinerant. An overall phase diagram for the alkaline iron selenides has been proposed, in which the orbital-selective Mott phase connects between the superconducting phase and the Mott-insulating parent state.

description: We use HST observations to study the LMC's young cluster NGC1844. We estimate the fraction and the mass-ratio distribution of photometric binaries and report that the main sequence presents an intrinsic breadth which can not be explained in terms of photometric errors only, and is unlikely due to differential reddening. We attempt some interpretation of this feature, including stellar rotation, binary stars, and the presence of multiple stellar populations with different age, metallicity, helium, or C+N+O abundance. Although we exclude age, helium, and C+N+O variations to be responsible of the main-sequence spread none of the other interpretations is conclusive.

description: We study a new mechanism for deflagration to detonation transition in thermonuclear supernovae (SNe Ia), based on the formation of shocks by amplification of sound waves in the steep density gradients of white dwarfs envelopes. Given a large enough jump in density a small pressure and velocity perturbation, produced by the turbulent deflagration, turns into a shock down of the gradient, where it will dissipate and heat up the media. With the right frequency and amplitude the heating can be enough to initiate a detonation, which can propagate backward and up the density gradient. We studied planar and spherical geometry. In the planar case we made a parametric study of the frequency and amplitude. We found it possible to obtain a detonation for perturbations down to Mach number M=0.003. In the spherical case, geometrical damping makes it harder to initiate a detonation, but considering a small He atmosphere (<0.01 Msol) makes it possible again to obtain a detonation down to small perturbation (M=0.002). In the context of thermonuclear supernovae, this could be a mean to turn a turbulent flame producing sound waves to a detonation.

description: We review a derivation of the numbers of RNA complexes of an arbitrary topology. These numbers are encoded in the free energy of the hermitian matrix model with potential V(x)=x^2/2-stx/(1-tx), where s and t are respective generating parameters for the number of RNA molecules and hydrogen bonds in a given complex. The free energies of this matrix model are computed using the so-called topological recursion, which is a powerful new formalism arising from random matrix theory. These numbers of RNA complexes also have profound meaning in mathematics: they provide the number of chord diagrams of fixed genus with specified numbers of backbones and chords as well as the number of cells in Riemann's moduli spaces for bordered surfaces of fixed topological type.

title:  Agave negatively regulates YAP and TAZ transcriptionally and post-translationally in osteosarcoma cell lines. A promising strategy for Osteosarcoma treatment
Creators: name: Ferraiuolo, Maria
Publisher: name: Sapienza Università Editrice
Year: 2022

description: Osteosarcoma (OS) is the most aggressive type of primary solid tumor that develops in bone. Whilst conventional chemotherapy can improve survival rates, the outcome for patients with metastatic or recurrent OS remains poor, so novel treatment agents and strategies are required. Previously published works indicate that Agave exhibits anticancer properties. In the present study, anticancer effects of Agave leaf extract were investigated in the OS cells, discovering that Agave inhibits cell growth and cell migration, and sensitizes OS cells to cisplatin (CDDP), to overcome chemoresistance. Agave’s mechanisms of action include an initial process in which Agave induces YAP/TAZ oncogenic protein degradation, followed by a secondary event whereby Agave inhibits YAP/TAZ transcription through NF-κB p65:p50 heterodimers deregulation.

description: Die vorliegende Arbeit möchte sich das Verhältnis von Begriffs- und Sozialgeschichte zunutze machen, um durch den Wandel des modernen Freiheitsbegriffes ein Licht auf sozialgeschichtliche Veränderungen zu werfen. Dadurch soll ein ideologiekritischer Beitrag zum Verständnis der aktuell ubiquitären Bezugnahmen auf Freiheit geleistet werden, der sich nicht nur in polemischen Klagen über die zunehmende Verarmung und Individualisierung erschöpft, sondern nach dessen Wahrheitsmoment fragt, welches darin besteht, dass sich in Ideologien immer auch gesellschaftliche Wirklichkeit ausdrückt. Zu diesem Zwecke soll idealtypisch der begriffsgeschichtliche Wandel von Freiheit auf dem Gebiet der Geistesgeschichte nachgezeichnet werden. Dabei soll vor dem Hintergrund der Arbeiten von Alexandra Schauer und Gerhard Stapelfeldt gezeigt werden, dass sich auch der semantische Wandel des Freiheitsbegriffes durch eine Kreisbewegung auszeichnet: In der vormodernen Freiheit, welche im Wesentlichen eine relationale Rechtskategorie darstellte, die ausschließlich auf das Bestehende bezogen war und dort die Privilegien zwischen Freien und Unfreien bezeichnete, zeigt sich deren Mangel an Abstraktion, der sich auf die Naturgebundenheit dieser Gesellschaftsformationen zurückführen lässt. Der moderne Freiheitsbegriff, der in dieser Arbeit paradigmatisch in den Schriften von Kant und Marx dargelegt wird, unterschied sich von diesem dadurch, dass er nicht mehr nur auf das Bestehende verwies, sondern ein Kollektivsingular von Freiheit entstand, welcher dieses Bestehende kritisch transzendierte. Sozialgeschichtlich wird dies auf den modernen Entzweiungszusammenhang zurückgeführt, der sich durch die Realabstraktionen der kapitalistischen Produktionsweise erklären lässt und eine Trennung zwischen Individuum, Gesellschaft und Natur bzw. zwischen Erfahrungsraum und Erwartungshorizont ermöglichte. In einem dritten Schritt wird anhand der Schriften von Hayek und Nassehi aufgezeigt, inwiefern der transzendente Gehalt im Begriff der Freiheit wieder einkassiert wurde und sich semantisch abermals vorrangig auf das Bestehende beschränkt. Die spätmoderne Freiheit verweist bei diesen nicht mehr auf ein zukünftig vernünftigeres Neues, in dem die Individuen sich aus den Zwängen des Bestehenden befreien, sondern zeichnet sich im Kern durch das Prinzip von Versuch und Irrtum innerhalb einer spontanen verdinglichten Ordnung aus. Sozialgeschichtlich wird dies auf die zunehmende Verinnerlichung gesellschaftlicher Zwänge und der Vorherrschaft der Gegenwart zurückgeführt.

description: It has long been expected that some massive stars produce stellar mass black holes (BHs) upon death. Unfortunately, the observational signature of such events has been unclear. It has even been suggested that the result may be an "unnova," in which the formation of a BH is marked by the disappearance of a star rather than an electromagnetic outburst. I argue that when the progenitor is a red supergiant, evidence for BH creation may instead be a ~3-10 day optical transient with a peak luminosity of ~10^{40}-10^{41} erg s^{-1}, a temperature of ~10^4 K, slow ejection speeds of ~200 km s^{-1}, and a spectrum devoid of the nucleosynthetic products associated with explosive burning. This signal is the breakout of a shock generated by the hydrodynamic response of a massive stellar envelope when the protoneutron star loses ~few*0.1Msun to neutrino emission prior to collapse to a BH. Current and future wide-field, high-cadence optical surveys make this an ideal time to discover and study these events. Motivated by the unique parameter space probed by this scenario, I discuss more broadly the range of properties expected for shock breakout flashes, with emphasis on progenitors with large radii and/or small shock energies. This may have application in a wider diversity of explosive events, from pair instability supernovae to newly discovered but yet to be understood transients.

title: Deploying single-cell transcriptomics for assessing CAR T cell generation: alleviating antiviral restriction factors enhances gene transfer
Creators: name: Charitidis, Filippos T.
Publisher: name: UNSPECIFIED
Year: 2023

description: Lentiviral vectors (LV) have become the dominant tool for stable gene transfer into lymphocytes including chimeric antigen receptor (CAR) gene delivery to T cells, a major breakthrough in cancer therapy. Yet, room for improvement remains, especially for the latest LV generations delivering genes selectively into T cell subtypes, a key requirement for in vivo CAR T cell generation. Towards improving gene transfer rates with these vectors, transcriptome analyses on human T lymphocytes after exposure to CAR-encoding conventional vector VSV-LV, and vectors targeted to CD8+ (CD8-LV) or CD4+ T cells (CD4-LV) was conducted. Genes related to quiescence and antiviral restriction were found to be upregulated in CAR-negative cells exposed to all types of LVs. Down-modulation of various antiviral restriction factors including the interferon-induced transmembrane proteins (IFITMs) was achieved with rapamycin as verified by mass spectrometry (LC-MS). Strikingly, rapamycin enhanced transduction by up to 7-fold for CD8-LV and CD4-LV without compromising CAR T cell activities, but did not improve VSV-LV. When administered to humanized mice, CD8-LV resulted in higher rates of GFP gene delivery as well as faster in vivo CAR T cell generation and tumor control. The data favor multi-omics approaches for improvements in gene delivery.

description: We consider parameter estimation for the spread of the Neolithic incipient farming across Europe using radiocarbon dates. We model the arrival time of farming at radiocarbon-dated, early Neolithic sites by a numerical solution to an advancing wavefront. We allow for (technical) uncertainty in the radiocarbon data, lack-of-fit of the deterministic model and use a Gaussian process to smooth spatial deviations from the model. Inference for the parameters in the wavefront model is complicated by the computational cost required to produce a single numerical solution. We therefore employ Gaussian process emulators for the arrival time of the advancing wavefront at each radiocarbon-dated site. We validate our model using predictive simulations.

description: Transport mechanisms in structurally ordered piezoelectric Ca3TaGa3Si2O14 (CTGS) single crystals are studied in the temperature range of 1000-1300 °C by application of the isotope 18O as a tracer and subsequent analysis of diffusion profiles of this isotope using secondary ion mass spectrometry (SIMS). Determined oxygen self-diffusion coefficients enable calculation of oxygen ion contribution to the total conductivity, which is shown to be small. Since very low contributions of the cations have to be expected, the total conductivity must be dominated by electron transport. Ion and electron conductivities are governed by different mechanisms with activation energies (1.9±0.1) eV and (1.2±0.07) eV, respectively. Further, the electromechanical losses are studied as a function of temperature by means of impedance spectroscopy on samples with electrodes and a contactless tone-burst excitation technique. At temperatures above 650 °C the conductivity-related losses are dominant. Finally, the operation of CTGS resonators is demonstrated at cryogenic temperatures and materials piezoelectric strain constants are determined from 4.2 K to room temperature.

description: A novel representation of functions, called generalized Taylor form, is applied to the filtering of white noise processes. It is shown that every Gaussian colored noise can be expressed as the output of a set of linear fractional stochastic differential equation whose solution is a weighted sum of fractional Brownian motions. The exact form of the weighting coefficients is given and it is shown that it is related to the fractional moments of the target spectral density of the colored noise.

description: Recently it has been proposed that the long-range electronic order formed by trimerons in magnetite should be frustrated due to the great degeneracy of arrangements linking trimerons. This result has important consequences as charge ordering from the condensed minority band electrons leads to a complex 3D antiferro orbital order pattern. Further more, the corner sharing tetrahedra structure of spinel B-sites supports frustration for antiferromagnetic alignments. Therefore frustration due to competing interactions will itself induce disorder and very likely frustration in the spin orientations. Here we present very low temperature specific heat data that show two deviations to the magnons and phonons contributions, that we analyze in terms of Schottky-type anomalies. The first one is associated with the thermal activation across both ferroelastic twin and ferromagnetic anti-phase domains. The second Schottky-type anomaly displays an inverse (1/H) field dependence which is a direct indication of the disordered glassy network with macroscopically degenerated singular ground states. © 2020, The Author(s).

description: We use the near--infrared Brγhydrogen recombination line as a reference star formation rate (SFR) indicator to test the validity and establish the calibration of the {\it Herschel} PACS 70 μm emission as a SFR tracer for sub--galactic regions in external galaxies. Brγoffers the double advantage of directly tracing ionizing photons and of being relatively insensitive to the effects of dust attenuation. For our first experiment, we use archival CFHT Brγand Ks images of two nearby galaxies: NGC\,5055 and NGC\,6946, which are also part of the {\it Herschel} program KINGFISH (Key Insights on Nearby Galaxies: a Far-Infrared Survey with Herschel). We use the extinction corrected Brγemission to derive the SFR(70) calibration for H{\sc ii} regions in these two galaxies. A comparison of the SFR(70) calibrations at different spatial scales, from 200 pc to the size of the whole galaxy, reveals that about 50% of the total 70μm emission is due to dust heated by stellar populations that are unrelated to the current star formation. We use a simple model to qualitatively relate the increase of the SFR(70) calibration coefficient with decreasing region size to the star formation timescale. We provide a calibration for an unbiased SFR indicator that combines the observed Hαwith the 70 μm emission, also for use in H{\sc ii} regions. We briefly analyze the PACS 100 and 160 μm maps and find that longer wavelengths are not as good SFR indicators as 70μm, in agreement with previous results. We find that the calibrations show about 50% difference between the two galaxies, possibly due to effects of inclination.

Das deutsche Bildungssystem hält nicht Schritt mit der steigenden Nachfrage nach Fachkräften. Zu viele Jugendliche haben keinen Berufsabschluss.
Im Jahr 2025 wird es rund 1,3 Millionen mehr gering Qualifizierte geben, als die Wirtschaft einsetzen kann. Schon seit rund 20 Jahren liegt deren Arbeitslosenquote über 20 Prozent. Die Nachfrage nach einfacher Arbeit sinkt, stattdessen sind zunehmend beruflich und akademisch ausgebildete Fachkräfte gefragt. 
Während sich Langzeitarbeitslosigkeit verfestigt, droht auf der anderen Seite Fachkräftemangel. Diese Lücke wird man nicht alleine durch Zuwanderung schließen können.
Notwendig ist eine präventive Bildungspolitik. Dazu muss u.a. die vorschulische Erziehung ausgebaut werden, um die sprachlichen Voraussetzungen für schulischen Erfolg zu legen. Die Zahl der Schulabbrecher muss gesenkt und mehr Ausbildungsplätze müssen geschaffen werden.

description: We propose a method to merge several paleoclimate time series into one that exhibits a consensus on the features of the individual times series. The paleoclimate time series can be noisy, nonuniformly sampled and the dates at which the paleoclimate is reconstructed can have errors. Bayesian inference is used to model the various sources of uncertainty and smoothing of the posterior distribution of the consensus is used to capture its credible features in different time scales. The technique is demonstrated by analyzing a collection of six Holocene temperature reconstructions from Finnish Lapland based on various biological proxies. Although the paper focuses on paleoclimate time series, the proposed method can be applied in other contexts where one seeks to infer features that are jointly supported by an ensemble of irregularly sampled noisy time series.

description: Microwave-induced plasma was used for the generation of plasma-processed air (PPA) and plasma-treated water (PTW). By this way, the plasma was able to functionalize the compressed air and the used water to antimicrobial effective agents. Their fungicidal effects by single and combined application were investigated on Candida albicans strain SC5314. The monoculture of C. albicans was cultivated on specimens with polymeric surface structures (PE-stripes). The additive as well as the synergistic fungicidal potential of PPA and PTW was investigated by different process windows of plasma exposure time (5-50 s) and sample treatment time with PPA/PTW (1-5 min). For a single PTW or PPA treatment, an increase in the reduction factor with the indicated treatment time was observed (maximum reduction factor of 1.1 and 1.6, respectively). In comparison, the combined application of PTW and then PPA resulted in antagonistic, additive and synergistic effects, depending on the combination. An application of the synergistically acting processes of PTW for cleaning and PPA for drying can be an innovative alternative to the sanitary processes currently used in production plants. © 2020 by the authors.

The work also investigates the effects of curing procedures on the ultimate phase morphology and mechanical properties of these thermoset-SB copolymer blends. It was found that at least 46 mol% of the epoxidation degree of the SB copolymer was needed to enable the miscibility of the modified block copolymer into the epoxy resin. Hence, an electron beam curing dose of ~50 kGy was needed to ensure the formation of micro- and nanostructured transparent blends. The micro- and nanophase-separated thermosets obtained were analyzed by optical as well as scanning and transmission electron microscopy. The mechanical properties of the blends were enhanced as shown by their impact strengths, indentation, hardness, and fracture toughness analyses, whereby the toughness values were found to mainly depend on the dose. Thus, we have developed a new route for designing dual-cured toughened micro- and nanostructured transparent epoxy thermosets with enhanced fracture toughness. © 2019 by the authors.

title: To the question about creating the kinematic structure without redundant links for cutting metal
Creators: name: Gudimova, L.N.
Publisher: name: Scientific Research Centre "MachineStructure"
Year: 2019

description: This article describes a device used for transverse cutting of metal in the process of movement, containing in its structure redundant bonds. It is known that the presence of such bonds reduces the efficiency of the mechanism and leads to increased wear of the contacting parts. Using the technique of eliminating redundant links, which consists in addressing the replacement of hinges on kinematic pairs of higher classes, the kinematic chain of non-redundant shears is proposed.

Creators: name: CALANDRIELLO, ANTONIO
Publisher: name: Sapienza Università Editrice
Year: 2022

description: Lo scopo di questa ricerca è stato quello di individuare come si sia sviluppato il ‘linguaggio grafico’ di Philibert de l’Orme, tentando di dimostrare che tale linguaggio stereotomico non derivi da un modello astratto, ma da una traduzione in grafici di un pensiero che si è formato con la pratica di cantiere e da una serie di altre pratiche ad esso connesse.
Le sezioni di stereotomia contenute nel Le Premier tome de l’Architecture di de l’Orme e i relativi traits sono divenuti gli strumenti principali che hanno aiutato la decifrazione dell’evoluzione del linguaggio grafico dell’autore, unitamente all’indagine del contesto storico-scientifico e le relative influenze, che provenienti dal passato, hanno aiutato a configurare il ‘pensiero’ di de l’Orme.
Molte delle operazioni proto-descrittive presenti all’interno del trattato si concretizzano nelle opere progettate da de L’Orme, tra il 1552 e il 1559, per Diana di Poitiers, e situate nel Castello di Anet (Francia), che hanno costituito il testimone per la verifica dell’esatta corrispondenza dei principi enunciati nel trattato. Infine, tali principi hanno trovato applicazione in un’ipotesi di ricostruzione digitale delle parti andate distrutte del criptoportico.

description: We present an analysis of EUV and soft X-ray emission detected toward Comet Lovejoy (C/2011 W3) during its post-perihelion traverse of the solar corona on December 16, 2011. Observations were recorded by the Atmospheric Imaging Assembly (AIA) aboard the Solar Dynamics Observatory and the X-Ray Telescope (XRT) aboard Hinode. A single set of contemporaneous images is explored in detail, along with prefatory consideration for time evolution using only the 171 A data. For each of the eight passbands, we characterize the emission and derive outgassing rates where applicable. As material sublimates from the nucleus and is immersed in coronal plasma, it rapidly ionizes through charge states seldom seen in this environment. The AIA data show four stages of oxygen ionization (O III - O VI) along with C IV, while XRT likely captured emission from O VII, a line typical of the corona. With a nucleus of at least several hundred meters upon approach to a perihelion that brought the comet to within 0.2 solar radii of the photosphere, Lovejoy was the most significant sungrazer in recent history. Correspondingly high outgassing rates on the order of 10^32.5 oxygen atoms per second are estimated. Assuming that the neutral oxygen comes from water, this translates to a mass-loss rate of about 9.5E9 g/s, and based only on the 171 A observations, we find a total mass loss of approximately 10^13 g over the AIA egress. Additional and supporting analyses include a differential emission measure to characterize the coronal environment, consideration for the opening angle, and a comparison of the emission's leading edge with the expected position of the nucleus.

Monte Carlo study of an unconventional superconducting phase in Ir-oxide J_{eff}=1/2 Mott insulators induced by carrier doping

description: Based on a microscopic theoretical study, we show that novel superconductivity is induced by carrier doping in layered perovskite Ir oxides where a strong spin-orbit coupling causes an effective total angular momentum J_{eff}=1/2 Mott insulator. Using a variational Monte Carlo method, we find an unconventional superconducting state in the ground state phase diagram of a t_{2g} three-orbital Hubbard model on the square lattice. This superconducting state is characterized by a d_{x^2-y^2}-wave "pseudospin singlet" formed by the J_{eff}=1/2 Kramers doublet, which thus contains inter-orbital as well as both singlet and triplet components of t_{2g} electrons. The superconducting state is found stable only by electron doping, but not by hole doping, for the case of carrier doped Sr_2IrO_4. We also study an effective single-orbital Hubbard model to discuss the similarities to high-T_c cuprate superconductors and the multi-orbital effects.

Coherently dedispersed gated imaging of millisecond pulsars

description: Motivated by the need for rapid localisation of newly discovered faint millisecond pulsars (MSPs) we have developed a coherently dedispersed gating correlator. This gating correlator accounts for the orbital motions of MSPs in binaries while folding the visibilities with best-fit topocentric rotational model derived from periodicity search in simultaneously generated beamformer output. Unique applications of the gating correlator for sensitive interferometric studies of MSPs are illustrated using the Giant Metrewave Radio Telescope (GMRT) interferometric array. We could unambiguously localise five newly discovered Fermi MSPs in the on-off gated image plane with an accuracy of +-1". Immediate knowledge of such precise position allows the use of sensitive coherent beams of array telescopes for follow-up timing observations, which substantially reduces the use of telescope time (~ 20X for the GMRT). In addition, precise a-priori astrometric position reduces the effect of large covariances in timing fit (with discovery position, pulsar period derivative and unknown binary model), which in-turn accelerates the convergence to initial timing model. For example, while fitting with precise a-priori position (+-1"), timing model converges in about 100 days, accounting the effect of covariance between position and pulsar period derivative. Moreover, such accurate positions allows for rapid identification of pulsar counterpart at other wave-bands. We also report a new methodology of in-beam phase calibration using the on-off gated image of the target pulsar, which provides the optimal sensitivity of the coherent array removing the possible temporal and spacial decoherences.

description: Mit der interkantonalen Vereinbarung über die Harmonisierung der obligatorischen Schule (EDK, 2007) wurde in der Schweiz der Grundstein für den Ausbau ganztägiger Bildungs- und Betreuungsangebote gelegt. Die Beitrittskantone verpflichten sich dazu, „ein bedarfsgerechtes Angebot für die Betreuung der Schülerinnen und Schüler“ anzubieten (EDK, 2007, Art. 11). In der pädagogischen und organisatorischen Gestaltung des Angebots besteht für die Kantone ein grosser Handlungsspielraum, was zu einer Pluralität von unterschiedlichen Ausgestaltungsformen beigetragen hat (EDK, 2016).
