STRATEGIE DI CONNESSIONE TESTUALE IN PRODUZIONI SCRITTE   D’ITALIANO L2: LA SUCCESSIONE TEMPORALE NEI TESTI NARRATIVI
Creators: name: D'Alfonso, Alberto
Publisher: name: Italiano LinguaDue
Year: 2015

description: Il contributo si occupa delle strategie utilizzate per la connessione testuale in italiano L2. Dopo un excursus sulle potenzialità del legame tra linguistica testuale e didattica dell’italiano, in cui si fa il punto su coesione e connessione, vengono esaminate le risorse linguistiche utilizzate a inizio periodo dagli apprendenti in produzioni scritte di tipo narrativo. Il materiale analizzato, suddiviso secondo i livelli di competenza, proviene dal corpus d’apprendimento ADIL2 dell’Università per Stranieri di Siena (brevemente illustrato in apertura). Le forme raccolte sono distribuite in base a cinque categorie: avverbi e congiunzioni usati come connettivi; riprese con dimostrativi; espressioni temporali in funzione testuale; altre espressioni temporali a inizio periodo; formule di scansione della narrazione. Dopo aver illustrato i dati sulla connessione nei testi (fornendo dati su frequenza assoluta, frequenza relativa e rapporto forme/occorrenze), l’indagine si concentra sull’espressione della successione temporale, intesa come scansione che a livello testuale separa un momento da quello che segue nel tempo: vengono illustrati e commentati i dati dell’indagine trasversale, in cui si documenta un quadro d’insieme sui comportamenti linguistici in diversi momenti d’apprendimento e livelli di competenza.

Textual connection strategies in written italian L2 production: temporal succession in narrative texts

This paper investigates connection strategies in Italian L2 texts. After a discussion on the potential link between textual linguistics and the teaching of Italian, which includes cohesion and connection, the linguistic resources used initially by learners in written narratives are examined. The material analyzed was divided according to the levels of competence and came from the Learning ADIL2 corpus compiled by the University for Foreigners in Siena (briefly described). The samples were divided in five categories: adverbs and conjunctions used as connectors; expressions with demonstratives; temporal expressions with textual functions; other temporal expressions used initially; scansion formulas of the narrative. After explaining the data regarding connections in the texts (absolute frequency, relative frequency and the form/occurrence ratio), the survey focuses on the expression of time sequences, meaning that scanning on the textual level separates one moment from what follows over time. The data is illustrated and commented on based on a transversal survey, which gives an overview of linguistic behavior during different periods of learning and at diverse skill levels.

description: The aim of the present thesis is the study of the request for the annulment of the procedure (Article 341 of the CCP), which is provided to the defendant, who was summoned as of known residence, but due to force majeure reasons or other insurmountable obstacles, failed to notify the Court of his/her impediment to attend the trial and demand a postponement and was, therefore, tried in absentia. The thesis consists of three chapters: (a) The first chapter refers to the application for the annulment of the procedure against convictions for misdemeanors (Article 341 of the CCP); (b) The second chapter analyzes the application of Article 341 of the CCP to the second degree trial (Article 341 in conjunction with Article 501 par.1 of the CCP); and (c) The third and final chapter analyzes the application for the annulment of the procedure against convictions for felonies (Article 435 CCP)
Linguistically interesting: Dutch domain adverbials in contrast
Creators: name: Diepeveen, Janneke
Publisher: name: JournaLIPP
Year: 2013

description: One might infer from the literature that Dutch may not use word-formation strategies for the linguistic realisation of the functional category of domain adverbials. English and German, however, are claimed to have very productive derivational patterns for the creation of domain adverbs. English systematically uses -wise (e.g. weatherwise) and German uses -mäßig or -technisch (e.g. wettermäßig, wettertechnisch). Starting from the observation that genetically related suffixes -gewijs, -matig and -technisch exist in Dutch, I investigate their potential to derive domain adverbs. I try to explain synchronic similarities and contrasts between Dutch, English and German patterns from a diachronic point of view as converging or diverging developments. The overall aim is to show that a contrastive investigation may contribute to a better understanding and a more accurate description of individual languages.

Wo versteckt sich (Ci-)Marron? Sprachkontakt als Auslöser des Bedeutungswandels von cimarrón/mar(r)on im Spanischen und im Antillen-Französischen
Creators: name: Klimenkowa, Alla

description: Die Ausgestaltung der Kontakte zur indigenen Bevölkerung insbesondere während der so genannten Antillen-Phase der Kolonisierung (1492-1519) bereicherte die Sprache spanischer Konquistadoren und Pioniere mit einer Fülle an lexikalischen Innovationen. Einen bedeutenden Anteil dieses neuen Vokabulars bildeten Lexeme indigener Herkunft, unter ihnen auch das Wort cimarrón/mar(r)on, das lange zu Unrecht als traditionelles spanisches Lexem (vgl. Corominas/Pascual 1980-1991; Friederici 1947: 191, s. vv. cimarrón) galt. DieserBeitrag stützt sich auf bisherige Hypothesen einer indigenen Herkunft von cimarrón und stellt neue Überlegungen zur Diskussion vor, und zwar - dass das Kopieren des Ausdrucks jeweils in der spanischen und französischen Sprachgemeinschaft auch unabhängig voneinander stattfinden konnte, und - dass sich das Spektrum der Verwendungsweisen von cimarrón und mar(r)on, auch wenn einige Bedeutungen deutliche semantische Übereinstimmungen aufweisen, in einem jeweils unterschiedlichen soziokulturellen Rahmen entwickelte. Dazu erfolgt eine kontrastive Gegenüberstellung der Verwendungen des spanischen cimarrón mit denen des französischen ma(r)ron auf Basis eines repräsentativen mQuellenmaterials. Im Fokus liegen aber nicht die einzelnen Sprachen an sich, sondern die Gemeinsamkeit kommunikativer Aktivitäten der Sprecher mit diversen sprachlichen Hintergründen in der karibischen Kontaktzone. Die Untersuchung trägt diesem Typ des Sprachkontakts explizit Rechnung, indem sie direkte und indirekte Verbindungen zwischen den interagierenden Sprachen berücksichtigt und zugleich die Möglichkeit einer polygenetischen Entwicklung bestimmter Verwendungsweisen sprachlicher Ausdrücke nicht ausschließt.

On the logical definability of certain graph and poset languages
Creators: name: Weil, Pascal
Publisher: name: arXiv
Year: 2006
Subjects: subject: Logic in Computer Science (cs.LO)
subject: FOS: Computer and information sciences

description: We show that it is equivalent, for certain sets of finite graphs, to be definable in CMS (counting monadic second-order logic, a natural extension of monadic second-order logic), and to be recognizable in an algebraic framework induced by the notion of modular decomposition of a finite graph. More precisely, we consider the set $F\_\infty$ of composition operations on graphs which occur in the modular decomposition of finite graphs. If $F$ is a subset of $F\_{\infty}$, we say that a graph is an $\calF$-graph if it can be decomposed using only operations in $F$. A set of $F$-graphs is recognizable if it is a union of classes in a finite-index equivalence relation which is preserved by the operations in $F$. We show that if $F$ is finite and its elements enjoy only a limited amount of commutativity -- a property which we call weak rigidity, then recognizability is equivalent to CMS-definability. This requirement is weak enough to be satisfied whenever all $F$-graphs are posets, that is, transitive dags. In particular, our result generalizes Kuske's recent result on series-parallel poset languages.

description: La concordanza tra genere e aggettivo è una caratteristica morfologica presente nella lingua italiana che è di difficile acquisizione da parte degli studenti che hanno familiarità solo con lingue in cui la concordanza è del tutto assente. Il presente articolo presenta uno studio condotto presso l’Università degli Studi di Milano che si propone di comparare l’efficacia di due diversi modelli di didattica nell’acquisizione della capacità di utilizzare correttamente la concordanza di genere tra nome e aggettivo da parte di discenti di L2 di madrelingua cinese. I due metodi utilizzati nella sperimentazione sono il Textual Enhancement (Sharwood Smith, 1991)e le Structured Input Activities (Van Patten 1996,2004). La sperimentazione, strutturata in tre fasi (Benati, 2004), è stata condotta presso il Centro Marco Polo su un gruppo di sinofoni, studenti di italiano L2 di livello A2-B1. I risultati hanno confermato che sia il Textual Enhancement che le  Structured Input Activities sono metodi d’insegnamento validi che aiutano i discenti ad elaborare particolari strutture morfologiche come la concordanza di genere. Tuttavia è emerso che il gruppo sottoposto al test con trattamento Structured Input Activities ha ottenuto risultati migliori rispetto al gruppo sottoposto a Textual Enhancement

The present study seeks to explore the effects that different types of instructions, namely Textual Enhancement and Structured Input Activities, can have on the acquisition of noun-adjective gender agreement by L2 Italian learners. A view of the theoretical backgrounds together with a review of the studies conducted on textual enhancement and structure input activities provide an overview of the main topics of the research. The present research aims to investigate whether textual enhancement and structured input activities help learners to make significant grammatical gains when exposed to these types of instruction and also which one facilitate better improvements. To do so, an experimental research has been conducted at the Università degli Studi di Milano in Milan, Italy. A group of Chinese student learning Italian has been pre-tested, then divided in two groups and exposed to different types of instructions, namely textual enhancement and structured input activities and finally tested in order to see the effects of the exposure to different types of instructions. Results showed that textual enhancement and structured input activities are positive instructions that help learners to notice the target form and comprehend it. Furthermore the results showed that the group who undertook the SIA tests showed a significantly larger improvement than the group who undertook the TE tests.

description: Softening material models are known to trigger spurious localizations.This may be shown theoretically by the existence of solutions with zero dissipation when localization occurs and numerically with spurious mesh dependency and localization in a single layer of elements. We introduce in this paper a new way to avoid spurious localization. The idea is to enforce a Lipschitz regularity on the internal variables responsible for the material softening. The regularity constraint introduces the needed length scale in the material formulation. Moreover, we prove bounds on the domain affected by this constraint. A first one-dimensional finite element implementation is proposed for softening elasticity and softening plasticity.

Il contributo si chiude facendo riferimento ad alcune ricadute didattiche dei concetti analizzati oltre che a testi teorici e manualistica di settore che sempre più sostengono qualitativamente la professione dell’alfabetizzatore e insegnante di italiano L2.

New alphabets for new citizens. The literacy challenge in a global world

This paper analyzes the socio-linguistic situation of foreign illiterate adults who acquire and learn oral skills and reading and writing in Italian L2. In particular, profiles are drawn for women from Maghreb and illiterate political refugees highlighting: a) common characteristics, such as the fact, for example, they are adult students who need to acquire cognitive and study skills (almost) from scratch and they are characterized by a type of concrete and action-oriented thinking, b) the characteristics of the target, like the different weight given to learning language skills linked to lifestyle and the more pressing needs of migrants, c) the gender variable and the different emotional barriers which the teacher must pay attention to in order to achieve mutual educational success and efficiency. In conclusion, the author refers to some educational implications of the concepts analyzed, in addition to considering how theoretical texts and manuals increasingly qualitatively illustrate the Italian L2 teacher’s role in literacy.

description: Low temperature behavior of the electronic specific heat $C(T)$ in the mixed state is by the self-consistent calculation of the Eilenberger theory. In addition to $γT$-term ($γ$ is a Sommerfeld coefficient), $C(T)$ has significant contribution of $T^2$-term intrinsic in the vortex state. We identify the origin of the $T^2$-term as (i) V-shape density of states in the vortex state and (ii) Kramer-Pesch effect of vortex core shrinking upon lowering $T$. These results both for full-gap and line node cases reveal that the vortex core is a richer electronic structure beyond the normal core picture.

Attraverso il framework di Andrew Littlejohn, specificamente pensato per l’analisi di materiale didattico secondo la sua strutturazione per task e non già quindi secondo le sue dinamiche applicative in classe, si è analizzato il manuale nella sua architettura, procedendo per tre tappe principali: Descrizione oggettiva, Descrizione soggettiva e Inferenza soggettiva. Si è così potuto scandagliarne la struttura profonda, quali meccanismi siano sottesi al suo utilizzo e la rispondenza tra task dichiarate e la realizzazione di esse.

Multilingualism and intercomprehension: an analysis of materials Eurom5 (using the Littlejohn framework)

This article offers the reader an example of analysis of EuRom5, a manual and website dedicated to Intercomprehension, designed for the study of one or more L2 of the romance family (Portuguese, Spanish, Catalan, Italian, French). This is a revised edition (2011) of EuRom4 updated to include the Catalan language. Through the framework of Andrew Littlejohn, specifically designed for the analysis of educational materials according to tasks rather than their practical implementation in the classroom, I have examined the structure of the manual in three main stages: Objective Description, Subjective Description and Subjective Inference. As a result I offer a in-depth understanding of its structure, of the dynamics underlying its use and of the correspondence between intended tasks and their practical execution.

Light scalar mesons as tetraquarks within QCD Sum Rules

Year: 2007
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: We examine the interpretation of the light scalar meson nonet as tetraquark states using QCD sum rules. With the interpolating current for the tetraquark states composed of scalar diquark and scalar antidiquark, first, we construct the QCD sum rules by means of the operator product expansion up to the operators of dimension 8 and show that there is no evidence of the coupling of the tetraquark states to the light scalar meson nonet. In order to have a stable sum rule, we propose a "good" interpolating current for the tetraquarks based on chirality arguments which includes scalar and pseudoscalar diquark--antidiquarks with equal weights. In particular, for the lowest tetraquark $σ$--meson, we perform detail analysis of the QCD sum rule and obtain mass for the $σ(600)$ around 780 MeV.

description: We propose a Bragg spectroscopy experiment to measure the onset of superfluid pairing in ultracold trapped Fermi gases. In particular, we study two component Fermi gases in the weak coupling BCS and BEC limits as well as in the strong coupling unitarity limit. The low temperature Bragg spectrum exhibits a gap directly related to the pair-breaking energy. Furthermore, the Bragg spectrum has a large maximum just below the critical temperature when the gas is superfluid in the BCS limit. In the unitarity regime, we show how the pseudogap in the normal phase leads to a significant suppression of the low frequency Bragg spectrum.

description: We present the results of high signal-to-noise ratio VLT spectropolarimetry of a representative sample of 25 bright type 1 AGN at z<0.37, of which nine are radio-loud. The sample covers uniformly the 5100 A optical luminosity at $L_{5100}\sim 10^{44}-10^{46}$ erg s$^{-1}$, and H$α$ width at FWHM$\sim 1000-10,000$~ km/s. We derive the continuum and the H$α$ polarization amplitude, polarization angle, and angle swing across the line, together with the radio properties. We find the following: 1. The broad line region (BLR) and continuum polarization are both produced by a single scattering medium. 2. The scattering medium is equatorial, and at right angle to the system axis. 3. The scattering medium is located at or just outside the BLR. The continuum polarization and the H$α$ polarization angle swing, can both serve as an inclination indicator. The observed line width is found to be affected by inclination, which can lead to an underestimate of the black hole mass by a factor of $\sim 5$ for a close-to face-on view. The line width measured in the polarized flux overcomes the inclination bias, and provides a close-to equatorial view of the BLR in all AGN, which allows to reduce the inclination bias in the BLR based black hole mass estimates.

description: Despite the large baryon-anti-baryon asymmetry in the observable Universe, the closely related phenomenon -- the violation of the combined charge and parity symmetry ($C\!P$V) -- has not been observed in the baryon sector in laboratories. In this paper, a new strategy for searching for $C\!P$V in heavy hadron multi-body decays is proposed, in which a set of novel observables measuring $C\!P$V in such decays -- the partial wave $C\!P$ asymmetries (PW$C\!P$As) -- are introduced. This strategy is model-independent and applicable to multi-body decays of heavy hadrons with arbitrary spin configurations in both initial and final states, and with any number of particles in the final state. It is especially applicable for $C\!P$V investigations in multi-body decays of heavy baryons. As applications of this strategy, we suggest to measure the PW$C\!P$As in some decay channels of bottom baryons such as $Λ_b^0\to p π^-π^+π^-$, $Λ_b\to p K^- π^+π^-$, $Λ^0_b\to pπ^-K^+K^-$, $Λ_b^0\toΛK^+π^-$, and $Λ_b^0\to p π^- K_s$.}

description: In this paper we present a theoretical and experimental study aimed at characterizing the hysteretic properties of viscoelastic materials. In the last decades viscoelastic materials have become a reference for new technological applications, which require lightweight, deformable but ultratough structures. The need to have a complete and precise knowledge of their mechanical properties, hence, is of utmost importance. The presented study is focused on the dynamics of a viscoelastic beam, which is both experimentally investigated and theoretically characterized by means of an accurate analytical model. In this way it is possible to fit the experimental curves to determine the complex modulus. Our proposed approach enables the optimal fitting of the viscoelastic modulus of the material by using the appropriate number of relaxation times, on the basis of the frequency range considered. Moreover, by varying the length of the beams, the frequency range of interest can be changed/enlarged. Our results are tested against those obtained with a well established and reliable technique as compared with experimental results from the Dynamic Mechanical Analysis (DMA), thus definitively establishing the feasibility, accuracy and reliability of the presented technique.

description: We calculate the Fermi energy dependence of the (time-averaged) current and shot noise in an impurity-free carbon bilayer (length $L\ll$ width $W$), and compare with known results for a monolayer. At the Dirac point of charge neutrality, the bilayer transmits as two independent monolayers in parallel: Both current and noise are resonant at twice the monolayer value, so that their ratio (the Fano factor) has the same 1/3 value as in a monolayer -- and the same value as in a diffusive metal. The range of Fermi energies around the Dirac point within which this pseudo-diffusive result holds is smaller, however, in a bilayer than in a monolayer (by a factor $l_{\perp}/L$, with $l_{\perp}$ the interlayer coupling length).

description: Effects of rapid stellar rotation on acoustic oscillation modes are poorly understood. We study the dynamics of acoustic rays in rotating polytropic stars and show using quantum chaos concepts that the eigenfrequency spectrum is a superposition of regular frequency patterns and an irregular frequency subset respectively associated with near-integrable and chaotic phase space regions. This opens new perspectives for rapidly rotating star seismology and also provides a new and potentially observable manifestation of wave chaos in a large scale natural system.

description: Structural features of the charge/orbital ordering (CO/OO) in single-layered manganites Pr1-xCa1+xMnO4 have been investigated systematically by transmission electron microscopy. Analyses of electron diffraction patterns as well as dark-field images have revealed that the CO/OO shows a striking asymmetric behavior as the hole doping x deviates from x = 0.5. The modulation wavenumber linearly decreases with increasing x in the over-hole-doped (x > 0.5) crystals, while much less dependent on x in the under-hole-doped (x < 0.5) crystals. A temperature-induced incommensurate-commensurate crossover is observed in 0.35 < x < 0.5 and x = 0.65. The correlation length of CO/OO in x = 0.3 was proven to become shorter than that in x > 0.3.

description: Reinforcement learning means learning a policy--a mapping of observations into actions--based on feedback from the environment. The learning can be viewed as browsing a set of policies while evaluating them by trial through interaction with the environment. We present an application of gradient ascent algorithm for reinforcement learning to a complex domain of packet routing in network communication and compare the performance of this algorithm to other routing methods on a benchmark problem.

description: The issue of how to create open-ended evolution in an artificial system is one the open problems in artificial life. This paper examines two of the factors that have some bearing on this issue, using the Tierra artificial life system. {\em Parsimony pressure} is a tendency to penalise more complex organisms by the extra cost needed to reproduce longer genotypes, encouraging simplification to happen. In Tierra, parsimony is controlled by the \verb+SlicePow+ parameter. When full parsimony is selected, evolution optimises the ancestral organism to produce extremely simple organisms. With parsimony completely relaxed, organisms grow larger, but not more complex. They fill up with ``junk''. This paper looks at scanning a range of \verb+SlicePow+ from 0.9 to 1 to see if there is an optimal value for generating complexity. Tierra (along with most ALife systems) use pseudo random number generators. Algorithms can never create information, only destroy it. So the total complexity of the Tierra system is bounded by the initial complexity, implying that the individual organism complexity is bounded. Biological systems, however, have plenty of sources of randomness, ultimately dependent on quantum randomness, so do not have this complexity limit. Sources of real random numbers exist for computers called {\em entropy gatherers} -- this paper reports on the effect of changing Tierra's pseudo random number generator for an entropy gatherer.

description: In this article we study a generalization of DGP scenarios, where the induced gravity is given by a $f(R)$ term. We obtain the effective gravitational equations and the effective FLRW cosmological equation on the brane of this model. We show that this generalization has also two regime, a 5D regime a low energies that has a self-accelerated branch of interest for cosmology and a 4D regime at high energies that it is described a modified gravitational theory.

description: The magnetic radiation of the fully-condensed states of $^{23}$Na condensates have been studied. A narrow characteristic spectral line with a wave length proportional to N^(-2/5) (N is the number of particles) and with a probability of transition proportional to N^(17/5) emitted (absorbed) by the condensate was found. It implies that short wave radiation with a huge probability of transition can be obtained if numerous atoms are trapped. A new technique developed by the authors, namely, the analytical forms of the fractional parentage coefficients, was used to calculate analytically the matrix elements between the total spin-states.

Active control of transport through nanopores

Subjects: subject: Soft Condensed Matter (cond-mat.soft)

description: Passive particle transport through narrow channels is well studied, while for active particle systems, it is not well understood. Here, we demonstrate the active control of the transport through a nanopore via mean-field analysis and molecular dynamics simulations. We prove that the active force enhances the transport efficiency with an effective diffusion coefficient $D_{eff} = D_t (1 + Pe^2/6)$, where $D_t$ is the translational diffusion coefficient, and $Pe$ is the Péclet number that determines the strength of the active force. For the number of particles inside the channel, it experiences subdiffusion at short times and then turns to normal at longer times. Finally, we extend our research for several sinusoidal shapes of the channel surface. More particles are trapped in the channel if the roughness of the channel surface is increased, resulting in fewer particles are transported from one side of the channel to the other.

Helical magnetic fields from Riemann coupling lead to baryogenesis

description: The spectrum of energy density fluctuations, baryon asymmetry, and coherent large-scale magnetic fields are the three observables that provide crucial information on physics at very high energies. Inflation can only provide a mechanism to explain the density perturbations, and the origin of primordial magnetic fields and baryon asymmetry require physics beyond the standard models of cosmology and particle physics. In this work, we show that the mechanism that leads to primordial helical fields also leads to baryogenesis at the beginning of the radiation-dominated epoch. The model we consider here consists of mass dimension 6 operators that include Riemann coupling between gravity and electromagnetic field without extending the Standard Model of particle physics. We explicitly show that the generation of primordial helical magnetic fields leads to baryogenesis. We further show that the model predicts the observed amount of baryon asymmetry of the Universe for a range of reheating temperatures consistent with the observations.

description: The spin-1/2 zig-zag Heisenberg ladder (J_1 - J_2 model) is considered. A new representation for the model is found and a saddle point approximation over the spin-liquid order parameter < \vec σ_{n-1}(\vec σ_{n}\times \vec σ_{n+1}) > is performed. Corresponding effective action is derived and analytically analyzed. We observe the presence of phase transitions at values J_2/J_1=0.231 and J_2/J_1=1/2.

The Reanalysis of German -end as a Marker of Gender-Sensitive Language Use. A Process of Exaptation
Creators: name: Bülow, Lars
name: Harnisch, Rüdiger
Publisher: name: JournaLIPP
Year: 2015

description: This article demonstrates the emergence of a new grammatical marker which has the function of expressing gender-sensitive language use. We propose that this linguistic innovation is a product of an individual’s use of language rather han a result of intentional planning. Both language-internal and language-external factors lead to linguistic innovations. This claim reflects that of Keller (2003), who explains that there is, on a macro-level, a spontaneous order triggered by concrete language use on a micro-level. To give an example, the participle suffix -end is currently used to meet the maxims of gender-sensitive language use. This is clearly a morphological innovation. What we thus observe is a process of reanalysis which can be interpreted as exaptation in the evolutionary sense of the word’s meaning. Exaptation means the evolution of a new function on the basis of an old form (see Gould/Vrba 1982; Simon 2010). In this article, we will demonstrate with select case studies from reformulated texts found in legal documents (e.g. the German Road Traffic Act) and study regulations that the present participle suffix -end (‘-ing’) is reanalysed in order to highlight gender-sensitive language use. Furthermore, this article will address the insistent dominance of the generic masculine in language. It seems that the generic masculine is a basic and highly economic grammatical category, verifiable not only in already engendered nouns but also in pronouns. The dominance of generic-masculine forms is also evidence for the great importance of generic language use in general.

description: This paper describes hardware and software improvements of the INRIM coaxial microcalorimeter together with their outcome on the primary power standard realization in the frequency band 0.05 - 40 GHz. A better temperature and power stabilization turned out to provide an improved signal/noise ratio and a drift reduction in every working condition of the microcalorimeter. The INRIM correction model is also compared to a traditional, but faster, one in terms of measurement uncertainty. Outcomes are presented in form of a 2.92 mm thermoelectric power sensor calibration together with results that show the improved stability and repeatability of the measurement system.

description: A significant fraction of baryons in galaxies are in the form of diffuse gas of the circumgalactic medium (CGM). One critical component of the multi-phases of CGM, the so-called "coronal" warm-hot phase gas ($\rm 10^{5}-10^{6}$ K) traced by O VI 1031.93, 1037.62 Å resonance lines, has rarely been detected in emission from galaxy halos other than Milky Way. Here we report four additional detections of O VI emission gas in the halos of nearby edge-on galaxies, NGC 4631 and NGC 891, using archival Far Ultraviolet Spectroscopic Explorer data and an updated data pipeline. We find the most intense O VI emission to be from fields forming a vertical line near the center of NGC 4631, despite the close proximity to the disk of two other fields. The detected O VI emission surface brightness are about 1.1$\pm 0.3$ $\times$ $10^{-18}$ to 3.9$\pm0.8$ $\times$ $10^{-18}$ ergs s$^{-1}$ cm$^{-2}$ arcsec$^{-2}$. The spatial distribution of the five 30" $\times$ 30" O VI detection fields in NGC 4631 can be interpreted as the existence of filamentary structures of more intense O VI emission superimposed within a diffuse and faint O VI halo in star-forming galaxies. Volume-filled O VI emission mapping is greatly needed to determine the structure and prevalence of warm-hot gas and the role it plays in the cycling of gas between the galaxy disk and the halo. Finally, we present the sensitivity of future funded and proposed UV missions (LUVOIR-A, LUVOIR-B, CETUS, and Aspera) to the detection of diffuse and faint O VI emission in nearby galaxy halos.
