On the Origin of the Type Ia Supernova Width-Luminosity Relation

description: Brighter Type Ia supernovae (SNe Ia) have broader, more slowly declining B-band light curves than dimmer SNe Ia. We study the physical origin of this width-luminosity relation (WLR) using detailed radiative transfer calculations of Chandrasekhar mass SN Ia models. We find that the luminosity dependence of the diffusion time (emphasized in previous studies) is in fact of secondary relevance in understanding the model WLR. Instead, the essential physics involves the luminosity dependence of the spectroscopic/color evolution of SNe Ia. Following maximum-light, the SN colors are increasingly affected by the development of numerous Fe II/Co II lines which blanket the B-band and, at the same time, increase the emissivity at longer wavelengths. Because dimmer SNe Ia are generally cooler, they experience an earlier onset of Fe III to Fe II recombination in the iron-group rich layers of ejecta, resulting in a more rapid evolution of the SN colors to the red. The faster B-band decline rate of dimmer SNe Ia thus reflects their faster ionization evolution.

description: Microinstabilities play important roles in both entropy generation and particle acceleration in collisionless shocks. Recent studies have suggested that in the transition zone of quasi-perpendicular ($Q_{\perp}$) shocks in the high-beta ($β=P_{\rm gas}/P_{\rm B}$) intracluster medium (ICM), the ion temperature anisotropy due to the reflected-gyrating ions could trigger the Alfvén ion cyclotron (AIC) instability and the ion-mirror instability, while the electron temperature anisotropy induced by magnetic field compression could excite the whistler instability and the electron-mirror instability. Adopting the numerical estimates for ion and electron temperature anisotropies found in particle-in-cell (PIC) simulations of $Q_{\perp}$-shocks with sonic Mach numbers, $M_{\rm s}=2-3$, we carry out a linear stability analysis for these microinstabilities. The kinetic properties of the microinstabilities and the ensuing plasma waves on both ion and electron scales are described for wide ranges of parameters, including the dependence on $β$ and the ion-to-electron mass ratio. In addition, the nonlinear evolution of induced plasma waves are examined by performing 2D PIC simulations with periodic boundary conditions. We find that for $β\approx 20-100$, the AIC instability could induce ion-scale waves and generate shock surface ripples in supercritical shocks above the AIC critical Mach number, $M_{\rm AIC}^{*} \approx 2.3$. Also electron-scale waves are generated primarily by the whistler instability in these high-$β$ shocks. The resulting multi-scale waves from electron to ion scales are thought to be essential in electron injection to the diffusive shock acceleration mechanism in $Q_{\perp}$-shocks in the ICM.

Πραγματοποιήθηκε σε μαθητές Τετάρτης τάξης του Δημοτικού Σχολείου, οι οποίοι παρήγαγαν κείμενα μετά την εφαρμογή δραστηριοτήτων δημιουργικής γραφής με τη χρήση εικονικού διδακτικού υλικού. Σκοπός της ήταν η συγκριτική μελέτη του βαθμού βελτίωσης των κειμένων, που παράγουν οι μαθητές, ως προς τα δημιουργικά τους χαρακτηριστικά, με τη χρήση τεχνικών δημιουργικής γραφής, που χρησιμοποιούν ως ερεθίσματα εικόνες ή κείμενα λογοτεχνικών βιβλίων. Επίσης εξετάστηκε εάν μαθητές με ειδικές εκπαιδευτικές ανάγκες, διαφοροποιούνται από τους τυπικούς συμμαθητές τους, ως προς τα ίδια δημιουργικά χαρακτηριστικά των κειμένων που παράγουν, κατά τη διάρκεια της παρέμβασης δημιουργικής γραφής. Τα αποτελέσματα της μελέτης συνηγορούν στην άποψη πως η χρήση εικονικού διδακτικού υλικού σε παρεμβάσεις δημιουργικής γραφής, βελτιώνει την παραγωγή ιδεών. Οι διαφορετικές δραστηριότητες με τη χρήση εικονικού διδακτικού υλικού, είχαν και διαφορετική επίδραση στα αποτελέσματα. Τέλος, οι δραστηριότητες δημιουργικής γραφής φαίνεται πως βελτιώνουν την επίδοση των παιδιών με ειδικές εκπαιδευτικές ανάγκες, χωρίς να εμφανίζεται σε μεγάλο βαθμό το φαινόμενο του Ματθαίου
description: The present study combines two different fields of research, creative writing and visual literacy. Fourth graders took part in the study, generating texts after being taught of creative writing activities where images were embedded. The aim of this study was to compare the degree of improvement of student texts’ creative characteristics, after intervention of creative writing using images or texts of children’s literacy books. Likewise, students’ with special educational needs differentiation from typical ones’ performance was examined. The results advocate the conclusion that creative writing activities use along with images improves the idea generation of 4th graders. Moreover, different activities with embedded images had different effect on students’ performance. Finally, creative writing activities also improved the performance of students with special educational needs, decreasing Mathew effect’s emergence

description: Properties of bars and bulges in the Hubble sequence are discussed, based on the analysis of 216 disk galaxies (S0s and spirals from NIRS0S and OSUBGS surveys, respectively). For that purpose we have collected together, and completed when necessary, the various analysis we have previously made separately for early and late types. We find strong photometric and kinematic evidence of pseudobulges in the S0-S0/a galaxies: their bulges are on average fairly exponential, inner disks are common (in 56%), and in many of the galaxies the bulges are rotationally supported. This would be difficult to understand in such gas poor galaxies as in S0s, if these pseudobulge candidates were formed by star formation in the disk in a a similar manner as in spirals. A more likely explanation is that pseudobulges in the early-type galaxies are bar-related structures, connected to the evolution of bars, which interpretation is supported by our Fourier analysis and structural decompositions. Bars in the early-type galaxies are found to have many characteristics of evolved systems: (1) they have flat-top/double peaked Fourier amplitude profiles, (2) bars have typically sharp outer cut-offs, (3) the higher Fourier modes appear in the amplitude profiles, and (4) many bars have also ansae-type morphologies. We show the distributions of bar strength in different Hubble type bins using four bar strength indicators, $Q_g$, $A_2$, $f_{bar}$ and the bar length, which are expected to give important clues for understanding the mechanism of how bars evolve.

description: We present a catalogue of white dwarf candidates selected from Gaia early data release three (EDR3). We applied several selection criteria in absolute magnitude, colour, and Gaia quality flags to remove objects with unreliable measurements while preserving most stars compatible with the white dwarf locus in the Hertzsprung-Russell diagram. We then used a sample of over 30 000 spectroscopically confirmed white dwarfs and contaminants from the Sloan Digital Sky Survey (SDSS) to map the distribution of these objects in the Gaia absolute magnitude-colour space. Finally, we adopt the same method presented in our previous Gaia DR2 work to calculate a probability of being a white dwarf (Pwd) for $\simeq$1.3 million sources which passed our quality selection. The Pwd values can be used to select a sample of $\simeq$359 000 high-confidence white dwarf candidates in the magnitude range 8< G <21. We calculated stellar parameters (effective temperature, surface gravity, and mass) for all these stars by fitting Gaia astrometry and photometry with synthetic models. We estimate an upper limit of 93 per cent for the overall completeness of our catalogue for white dwarfs with G $\leq$20 mag and effective temperature (Teff)>7000K, at high Galactic latitudes (|b|>20°). Alongside the main catalogue we include a reduced-proper-motion extension containing $\simeq$10 200 white dwarf candidates with unreliable parallax measurements which could, however be identified on the basis of their proper motion. We also performed a cross-match of our catalogues with SDSS DR16 spectroscopy and provide spectral classification based on visual inspection for all resulting matches.

title: Quality, ambition and strategy: collecting French art for the Musée de Lyon (1900 - 1914)

description: This dissertation covers the history of municipal collecting in Lyon during the years 1900 – 1914. Chapter One deals with the tenure of Édouard Aynard (1837 – 1913), the prominent Lyonnais statesman and Président of the Conseil d’Administration des Musées (1878 – 1897), who sought to elevate the status of the museum in France and Europe by improving the quality of the collection with acquisitions made by purchase. Although he was unable to achieve results that reflected the scope of his ambition, Aynard nevertheless developed strategic policies that appear to have had an immediate and lasting influence on collecting in Lyon. In Chapter Two, the reasons why the Commission Consultative des Musées was established in 1897 are examined. This restructure of the management and organisation of the group was significant because it led to greater diversification of its membership and resulted in a firm emphasis being placed on consensus decision-making. The five key individuals responsible for shaping attitudes after 1900 are also introduced in this chapter: Victor Augagneur (1855 – 1931), Édouard Herriot (1872 – 1957), Raymond Tripier (1838 – 1916), Émile Bertaux (1869 – 1917) and Richard Cantinelli (1870 – 1932). The respective backgrounds of these men are outlined, particularly in the context of their outlooks on the Dreyfus Affair and the Separation of Church and State. In Chapter Three, the issue of regional pride is considered through an examination of the acquisition of works by artists from Lyon and the wider region. Chapter Four consists of a series of six case studies which show that a main priority for the Commission was to actively seek out paintings by major French nineteenth-century artists. This area of collecting activity was important and it is examined in detail in order to determine how, and why, the museum became the first in France to purchase works by Claude Monet (1840 – 1926) and Paul Gauguin (1848 – 1903), in 1902 and 1913 respectively. Chapter Five treats the long collaboration between the Commission and Auguste Rodin (1840 – 1917) which spanned the period 1903 – 1912. It analyses the circumstances that gave rise to Tripier, Herriot and Cantinelli consciously seeking to develop and maintain a strong working relationship with the artist. The success of the approach taken was such that it resulted in Lyon accumulating the most comprehensive collection of works by the sculptor held by any museum in France outside Paris.
title: Performance Investigation of Integrated Gasification Combined Cycle Power Plant for Polygeneration

Publisher: name: UNSPECIFIED
Year: 2022

description: Energy and environment are playing an important role in shaping the world at present and the path ahead into the future. Both affect the aspects of the economy, politics, health, and welfare. In addition, the growth of wind and photovoltaic plants has greatly increased the demand for flexible generation or storage options in the electricity market due to their fluctuation. The Integrated Gasification Combined Cycle (IGCC) with carbon capture for polygeneration of power and chemicals features the advantages of flexible power generation that has low CO₂ emissions, alongside essential chemicals for the industry or even production of fuels that for storage and then to be utilized during the peak time. Moreover, the ability to use biomass and Refuse Derived Fuel (RDF) as feedstock for IGCC contributes to waste management and better use of the resources. In the scope of this work, a process simulation model of an IGCC using Aspen Plus was developed based on a pilot-scale 0.5 MWth HTW gasifier and gas purification plant installed at TU Darmstadt. The gasification and purification pilot plant model was scaled up and then integrated with a CCPP for power generation. For the power generation part, a process simulation model of Combined Cycle Power Plant (CCPP) was built based on a 360 MWel General Electric (GE) STAG 109FA CCPP located at Prai in Malaysia. For chemical production, a methanol synthesis unit was also modeled and integrated with the IGCC model to enable polygeneration of electricity and methanol in an IGCC plant. To improve the performance of the IGCC, heat integration between the heat recovery steam generator (HRSG) and the syngas production process (gasification and purification) was applied. Additionally, an acid gas removal (AGR) process was adopted for the IGCC model. In this respect, three process simulation models for AGR were developed using three different solvents (Selexol, Rectisol, and a-MDEA) and then evaluated seeking a better performance of the IGCC. Furthermore, co-gasification of coal and refuse derived fuel in different mixing ratios were used and investigated. The evaluation of the developed IGCC power plant model for flexible polygeneration using HTW gasification technology shows a promising electrical efficiency of about 37.48% with a carbon capture rate of 90%. Also, the comparison between the three AGR processes shows that the Selexol process is the most efficient. Therefore, this process was used in the final configuration of the IGCC plant. Finally, a thermo-economic evaluation under volatile selling prices of IGCC products was executed to investigate the production regime and to make better decisions for production.

description: We obtain local numerators satisfying the BCJ color-kinematics duality at one loop for super-Yang-Mills theory in ten dimensions. This is done explicitly for six points via the field-theory limit of the genus-one open superstring correlators for different color orderings, in an analogous manner to an earlier derivation of local BCJ-satisfying numerators at tree level from disk correlators. These results solve an outstanding puzzle from a previous analysis where the six-point numerators did not satisfy the color-kinematics duality.

description: Lattice reconstruction in twisted transition-metal dichalcogenide (TMD) bilayers gives rise to piezo- and ferroelectric moiré potentials for electrons and holes, as well as a modulation of the hybridisation across the bilayer. Here, we develop hybrid $\mathbf{k}\cdot \mathbf{p}$ tight-binding models to describe electrons and holes in the relevant valleys of twisted TMD homobilayers with parallel (P) and anti-parallel (AP) orientations of the monolayer unit cells. We apply these models to describe moiré superlattice effects in twisted WSe${}_2$ bilayers, in conjunction with microscopic \emph{ab initio} calculations, and considering the influence of encapsulation, pressure and an electric displacement field. Our analysis takes into account mesoscale lattice relaxation, interlayer hybridisation, piezopotentials, and a weak ferroelectric charge transfer between the layers, and describes a multitude of possibilities offered by this system, depending on the choices of P or AP orientation, twist angle magnitude, and electron/hole valley.

description: The purpose of the present study was the investigation of the results deriving from the teaching approach of contemporary children’s short story’s techniques in the Fourth Grade. More precisely, the degree of understanding basic techniques of contemporary children’s short story was investigated. Furthermore, the use of these techniques by the students of the Fourth Grade in the generation of fiction through activities of creative writing was explored. The findings showed that creative writing enabled students to understand and use specific literacy techniques of contemporary children’s short story in their fictional written speech. Teaching approaches of contemporary children’s short story’s techniques through creative writing improved the active participation of students within the teaching process. The variation in participation and the different levels of learning performance among the students was minimized, while the appropriate environment was created so that the students could be involved actively and be stimulated in order to create fiction

description: In this note we study a positivity notion for the curvature of the Bismut connection; more precisely, we study the notion of \emph{Bismut-Griffiths-positivity} for complex Hermitian non-Kähler manifolds. Since the Kähler-Ricci flow preserves and regularizes the usual Griffiths positivity we investigate the behaviour of the Bismut-Griffiths-positivity under the action of the Hermitian curvature flows. In particular we study two concrete classes of examples, namely, linear Hopf manifolds and six-dimensional Calabi-Yau solvmanifolds with holomorphically-trivial canonical bundle. From these examples we identify some HCFs which do not preserve Bismut-Griffiths-non-negativity.

A transfer matrix study is done in a simplified theoretical model, for which an enhanced sensitivity of the reflection interference pattern to the output medium is demonstrated, in the typical refractive index range of liquid media. An experimental configuration using a cascaded Fabry-Perot microcavity coated by a graphene oxide/polyethylenimine (GO/PEI) multilayered structure is demonstrated. Its cost effective chemical production method makes graphene oxide-based hybrid coatings excellent candidates for future real-life sensing devices.

Psychoanalytic theory in the context of a transformative politics
Creators: name: Glynos, Leonidas Jason
Publisher: name: University of British Columbia
Year: 2009

description: In contemplating social change in the context of policy development and legal decision-making we are necessarily led to consider what the limits are to such change. And it is not surprising to find this issue gaining widespread currency in contemporary legal and political debates, especially when viewed against the background of the growing number of new social movements: feminism, critical race, anti-poverty, environmentalism, and so on. Our thesis suggests that a psychoanalytic approach can successfully contribute to this critical discussion. In a first approach, our thesis develops some basic psychoanalytic categories, such as ‘fantasy’ and ‘identification,’ to show how Lacan’s view of the subject as a lack yields some surprisingly fruitful insights. What we have in mind here is his view that the subject is not a fully-formed individual with a clear and undisputed will. Rather, I.acan suggests that it is the very absence of a concrete will which defmes the human subject. These insights are further developed in relation to the standard theoretical categories of ‘power relations’ and ‘structural constraint’. We thus demonstrate, for example, how psychoanalytic ideas can further the debates over ideological critique and ‘false-consciousness’. Now, in making our analysis relevant to contemporary political and legal scholarship, we have applied our theoretical framework to the discussion of the rights discourse. We find that many of the impasses centering on the public-private issue; on the formal versus substantive opposition; on the question of whether rights reproduce the capitalist mode of production; can be usefully portrayed in terms of the assumptions that underlie legal positivism and legal postmodernism; and we show how Lacan can provide us with a much-needed alternative account of the rights phenomenon. In this new formulation, rights users are tied directly to the subject-as-lack. And, contrary to a reactionary interpretation of this new formulation which might point to an apparent pessimism and apathy, we find that our narrative opens up the way to a highly productive and passionate ethics. We immediately see the relevance of such contemplations to political and legal strategists. We argue that Justice is impossible in the strictest sense of the term, and that our proposed ethics provides us with a means to cope with this knowledge. We suggest adopting a paradoxical stance in which Justice is conceivable, and in this sense possible, on the basis of a constitutive impossibility. Our thesis demonstrates how the work of Slavoj Zizek, Ernesto Laclau, Chantal Mouffe, Joan Copjec, and Renata Saleci, provide us with a panoply of remarkably sophisticated (Lacanian) theoretical tools for the purposes of presenting this paradoxical relationship.

description: Using the Infrared Array Camera and the Multiband Imaging Photometer aboard the {\it Spitzer Space Telescope}, we have obtained images of the Lupus 3 star-forming cloud at 3.6, 4.5, 5.8, 8.0, and 24 \micron. We present photometry in these bands for the 41 previously known members that are within our images. In addition, we have identified 19 possible new members of the cloud based on red 3.6-8.0 \micron colors that are indicative of circumstellar disks. We have performed optical spectroscopy on 6 of these candidates, all of which are confirmed as young low-mass members of Lupus 3. The spectral types of these new members range from M4.75 to M8, corresponding to masses of 0.2-0.03 $M_\odot$ for ages of $\sim1$ Myr according to theoretical evolutionary models. We also present optical spectroscopy of a candidate disk-bearing object in the vicinity of the Lupus 1 cloud, 2M 1541-3345, which Jayawardhana & Ivanov recently classified as a young brown dwarf ($M\sim0.03$ $M_\odot$) with a spectral type of M8. In contrast to their results, we measure an earlier spectral type of M5.75$\pm$0.25 for this object, indicating that it is probably a low-mass star ($M\sim0.1$ $M_\odot$). In fact, according to its gravity-sensitive absorption lines and its luminosity, 2M 1541-3345 is older than members of the Lupus clouds ($τ\sim1$ Myr) and instead is probably a more evolved pre-main-sequence star that is not directly related to the current generation of star formation in Lupus.

description: We study the behavior of metric perturbations in a recently proposed model of phantom dark energy with tachyonic instability at long wavelengths. We find that metric perturbations exponentially grow in time, starting from very small values determined by vacuum fluctuations, and may become sizeable at late times. This property may be of interest for phenomenology.

description: We continue our study of the optical properties of the solar gravitational lens (SGL). Taking the next step beyond representing it as an idealized monopole, we now characterize the gravitational field of the Sun using an infinite series of multipole moments. We consider the propagation of electromagnetic (EM) waves in this gravitational field within the first post-Newtonian approximation of the general theory of relativity. The problem is formulated within the Mie diffraction theory. We solve Maxwell's equations for the EM wave propagating in the background of a static gravitational field of an extended gravitating body, while accounting for multipole contributions. Using a wave-theoretical approach and the eikonal approximation, we find an exact closed form solution for the Debye potentials and determine the EM field at an image plane in the strong interference region of the lens. The resulting EM field is characterized by a new diffraction integral. We study this solution and show how the presence of multipoles affects the optical properties of the lens, resulting in distinct diffraction patterns. We identify the gravitational deflection angle with the individual contributions due to each of the multipoles. Treating the Sun as an extended, axisymmetric, rotating body, we show that each zonal harmonics causes light to diffract into an area whose boundary is a caustic of a particular shape. The appearance of the caustics modifies the point-spread function (PSF) of the lens, thus affecting its optical properties. The new wave-theoretical solution allows the study gravitational lensing by a realistic lens that possesses an arbitrary number of gravitational multipoles. This {\em angular eikonal method} represents an improved treatment of realistic gravitational lensing. It may be used for a wave-optical description of many astrophysical lenses.

description: Στην παρούσα ερευνητική εργασία διερευνήθηκε εάν η εφαρμογή δυο διαφορετικών εργαλείων καταγραφής ιδεών, προκαλεί διαφορετικές εννοιολογήσεις στην σκέψη παιδιών προσχολικής ηλικίας. Για την διερεύνησή αυτή, εφαρμόστηκαν δυο εργαλεία καταγραφής ιδεών, σε δυο ομάδες παιδιών (σύνολο 28 παιδιά) για τα φαινόμενα της τήξης και της πήξης. Έτσι, στην ομάδα 1 πραγματοποιήθηκε προ έλεγχος με την εφαρμογή του εργαλείου των «φωτογραφιών», ακολούθησε διδακτική παρέμβαση και τέλος στην ομάδα 1 πραγματοποιήθηκε μετά έλεγχος με την εφαρμογή και πάλι του εργαλείου των «φωτογραφιών». Στην ομάδα 2 πραγματοποιήθηκε προ έλεγχος με την εφαρμογή του εργαλείου της «αφήγησης», ακολούθησε διδακτική παρέμβαση και τέλος στην ομάδα 2 πραγματοποιήθηκε μετά έλεγχος με την εφαρμογή και πάλι του εργαλείου της «αφήγησης». Από τα δεδομένα που συλλεχθήκαν, συγκρίθηκαν μεταξύ τους τα δεδομένα προελέγχου Α με τα δεδομένα προελέγχου Β, καθώς επίσης συγκρίθηκαν τα δεδομένα μετά ελέγχου Α με τα δεδομένα μετά ελέγχου Β. Τα αποτελέσματα της συγκεκριμένης έρευνας αναδεικνύουν ότι στην ανίχνευση ιδεών κατά τον προέλεγχο, στοιχεία του κάθε πλαισίου εμπεριέχονται στις εξηγήσεις των παιδιών με εμφανή την επιρροή του κάθε πλαισίου σε ορισμένες εννοιολογήσεις τους, ωστόσο συνολικά εμφανίζουν σχετική ισοδυναμία. Από την άλλη, στον μετά έλεγχο, η επιρροή των πλαισίων μειώνεται και συνολικά τα δυο εργαλεία εμφανίζουν σχετική ισοδυναμία ως προς τους παραγόμενους συλλογισμούς
description: In this research study, it has been investigated whether the implementation of two different logging tools causes different conceptions in preschoolers’ thinking. More specifically, for this investigation, two logging tools were implemented on two groups of children (a total of 28 children) regarding the phenomena of melting and coagulation. In this context the investigation process on Group 1 had as follows: at first a pre-test was implemented using the "Photos" tool, a didactic intervention was carried out, and finally a post-test was also implemented using again "Photos" as logging tool. As regards the investigation on Group 2, the identical process was followed but “narration” was used as logging tool of “photos”. From the collected data, data of pre-test A was compared with the data of pre-test B, and also the data of post-test A was compared with data of post-test B. The results of this research study show that in the pre-tests, elements of each frame are contained in children's explanations, with the apparent influence of each frame on some of their conceptions, but in total, they are relatively equivalent. On the other hand, in the post-tests, the influence of the frames decreases and, in total, the two tools appear a relative equivalence in terms of reasoning
Disentangling (2+1)d Topological States of Matter with the Entanglement Negativity

description: We use the entanglement negativity, a bipartite measure of entanglement in mixed quantum states, to study how multipartite entanglement constrains the real-space structure of the ground state wavefunctions of $(2+1)$-dimensional topological phases. We focus on the (Abelian) Laughlin and (non-Abelian) Moore-Read states at filling fraction $ν=1/m$. We show that a combination of entanglement negativities, calculated with respect to specific cylinder and torus geometries, determines a necessary condition for when a topological state can be disentangled, i.e., factorized into a tensor product of states defined on cylinder subregions. This condition, which requires the ground state to lie in a definite topological sector, is sufficient for the Laughlin state. On the other hand, we find that a general Moore-Read ground state cannot be disentangled even when the disentangling condition holds.

description: We present a unified algebraic Bethe ansatz for open vertex models which are associated with the non-exceptional $A^{(2)}_{2n},A^{(2)}_{2n-1},B^{(1)}_n,C^{(1)}_n,D^{(1)}_{n}$ Lie algebras. By the method, we solve these models with the trivial K matrix and find that our results agree with that obtained by analytical Bethe ansatz. We also solve the $B^{(1)}_n,C^{(1)}_n,D^{(1)}_{n}$ models with some non-trivial diagonal K-matrices (one free parameter case) by the algebraic Bethe ansatz.

description: Describe the characteristics, treatment patterns and outcomes of Chinese patients with unresectable advanced/metastatic (UAM) gastric/gastroesophageal junction adenocarcinoma (GA/GEJA). This multicenter, retrospective, observational study included adults diagnosed with UAM GA/GEJA in China from 2017–2020. Among 2,745 patients, 1,902, 729, and 284 received first-, second- and third-line (1 L, 2 L and 3 L) therapy–respectively. Most patients received chemotherapy alone in 1 L (84.1%) and 2 L (63.6%), and targeted-therapy–based treatment in 3 L (49.2%). Median real-world progression-free survival (rwPFS) was 6.5, 4.2, and 3.2 months in 1 L, 2 L, and 3 L, respectively. Chinese patients with UAM GA/GEJA mainly received chemotherapy alone in 1 L/2 L and targeted therapy in 3 L. Median rwPFS was short in all lines, highlighting the need for more effective treatments. Gastric (stomach) cancer is one of the leading causes of cancer-related death globally, and nearly four-in-ten of those cases and deaths occur in China. Despite this high disease burden, real-world data on clinical outcomes and which treatments are used are lacking from Chinese patients with gastric cancer. Therefore, we examined patient records from four large hospitals in China between 2017 and 2020, selecting adults diagnosed with gastric cancer (or a type of cancer between the stomach and esophagus), whose disease was advanced-stage or had spread. We analyzed data on the time until patients’ tumors grew or spread (disease progression), the patient had to switch therapies because of disease progression, or the patient died (together called real-world progression-free survival, or rwPFS). We also tracked which treatments the patients were using and when this changed. From the large number of patients (2,745), we found that the treatment patterns generally reflected established guidelines at the time, with the majority of initial treatments used either first or second being based on chemotherapy. We found that the median rwPFS was short, decreasing from 6.5 months, to 4.2 months, then 3.2 months each time the therapy needed to be changed. These findings provide important real-world data that improve our understanding of current treatments and real-world outcomes in Chinese patients with this type of cancer. Our results also highlight a need for more effective and novel treatment options, with the ultimate goal of improving treatment outcomes.

description: After briefly reviewing the good agreement between large-scale observations and the predictions of the now-standard CDM theory and problems with the MOND alternative, I summarize several of the main areas of possible disagreement between theory and observation: galaxy centers, dark matter substructure, angular momentum, and the sequence of cosmogony, updating earlier reviews [1]. All of these issues are sufficiently complicated that it is not yet clear how serious they are, but there is at least some reason to think that the problems will be resolved through a deeper understanding of the complicated "gastrophysics" of star formation and feedback from supernovae and AGN.

description: We give a brief review of the twistor string approach to supersymmetric Yang-Mills theories with an emphasis on the different formulations of (super)string models in supertwistor space and their superspace form. We discuss the classical equivalence among the Siegel closed twistor string and the Lorentz harmonics formulation of the (N=4) tensionless superstring, and notice the possible relation of the twistor string to the D=10 Green-Schwarz superstring action, as well as to models in the enlarged, tensorial superspaces that are relevant in higher spin theories.
