description: The analysis of multiple populations (MPs) in globular clusters (GCs) has become a forefront area of research in astronomy. Multiple red giant branches (RGBs), subgiant branches (SGBs), and even main sequences (MSs) have now been observed photometrically in many GCs. UV photometry has been crucial in discovering and analyzing these MPs, but the Johnson U and the Stromgren and Sloan u filters that have generally been used are relatively inefficient and very sensitive to reddening and atmospheric extinction. In contrast, the Washington C filter is much broader and redder than these competing UV filters. Here we investigate the use of the Washington system to uncover MPs using only a 1-meter telescope. Our analysis of the well-studied GC NGC 1851 finds that the C filter is both very efficient and effective at detecting its previously discovered MPs in the RGB and SGB. Remarkably, we have also detected an intrinsically broad MS best characterized by two distinct but heavily overlapping populations that cannot be explained by binaries, field stars, or photometric errors. The MS distribution is in very good agreement with that seen on the RGB, with ~30% of the stars belonging to the second population. There is also evidence for two sequences in the red horizontal branch, but this appears to be unrelated to the MPs in this cluster. Neither of these latter phenomena have been observed previously in this cluster. The redder MS stars are also more centrally concentrated than the blue MS. This is the first time MPs in a MS have been discovered from the ground, and using only a 1-meter telescope. The Washington system thus proves to be a very powerful tool for investigating MPs, and holds particular promise for extragalactic objects where photons are limited.

description: We evaluated factors associated with improvement in neurocognitive performance in 258 HIV-infected adults with baseline CD4 lymphocyte counts above 350 cells/mm3 randomized to intermittent, CD4-guided antiretroviral therapy (ART) (128 participants) versus continuous therapy (130) in the Neurology substudy of the Strategies for Management of Antiretroviral Therapy trial. Participants were enrolled in Australia, North America, Brazil, and Thailand, and neurocognitive performance was assessed by a five-test battery at baseline and month 6. The primary outcome was change in the quantitative neurocognitive performance z score (QNPZ-5), the average of the z scores of the five tests. Associations of the 6-month change in test scores with ART use, CD4 cell counts, HIV RNA levels, and other factors were determined using multiple regression models. At baseline, median age was 40 years, median CD4 cell count was 513 cells/mm3, 88 % had plasma HIV RNA ≤400 copies/mL, and mean QNPZ-5 was −0.68. Neurocognitive performance improved in both treatment groups by 6 months; QNPZ-5 scores increased by 0.20 and 0.13 in the intermittent and continuous ART groups, respectively (both P<0.001 for increase and P=0.26 for difference). ART was used on average for 3.6 and 5.9 out of the 6 months in the intermittent and continuous ART groups, respectively, but the increase in neurocognitive test scores could not be explained by ART use, changes in CD4, or plasma HIV RNA, which suggests a practice effect. The impact of a practice effect after 6 months emphasizes the need for a control group in HIV studies that measure intervention effects using neurocognitive tests similar to ours.

description: We present a first principles molecular dynamics (FPMD) study of the interaction of low energy, positively charged, carbon (C+) projectiles with amorphous solid water clusters at 30 K. Reactions involving the carbon ion at an initial energy of 11 eV and 1.7 eV with 30-molecule clusters have been investigated. Simulations indicate that the neutral isoformyl radical, COH, and carbon monoxide, CO, are the dominant products of these reactions. All these reactions are accompanied by the transfer of a proton from the reacting water molecule to the ice, where it forms a hydronium ion. We find that COH is formed either via a direct, "knock-out", mechanism following the impact of the C+ projectile upon a water molecule or by creation of a COH_2^+ intermediate. The direct mechanism is more prominent at higher energies. CO is generally produced following the dissociation of COH. More frequent production of the formyl radical, HCO, is observed here than in gas phase calculations. A less commonly occurring product is the dihydroxymethyl, CH(OH)_2, radical. Although a minor result, its existence gives an indication of the increasing chemical complexity which is possible in such heterogeneous environments.

description: Urban Transformations is a series of pilot plans that straddle between legal and irregular, describe spatial snapshots and protocols, teasing the existing legislation, with the aim of delivering spatial justice. The identification and recording of the typologies of the urban voids of the greek metropolis is followed by a set of architectural “reactions” which, by questioning the existing concept of ownership, attempt to offer appropriate conditions for the emergence of common spaces, the provision of shelter, the strengthening of the residents’ sense of community and the claim to their right to the city. In this proposal two systems-tools are described, which act in parallel and supportively, penetrate boundaries, liberate and make accessible the ground level of the city and create a free and unhindered accessible field for the utilization, sharing and enjoyment of the space. The area of Vardari in Thessaloniki is used as an exemplary place where spatial possibilities of the two practices’ application is represented.

description: The Coinage of the Roman Republican Online (CRRO), a joint American Numismatic Society and British Museum collaboration, was published online in early 2015. This digital corpus, based on Michael Crawford's 1974 Roman Republic Coinage, has since drawn together more than 60,000 example specimens from dozens of collections. More recently, the information system on which CRRO lies has been expanded to accommodate the Roman Republican Die Project. Some 10,000 coins from the archival research cards and binders of Richard Schaefer are presently entered into a database, linking to unique identifiers that reflect his die attributions. The link between die IDs to specimens to types enables a relatively instantaneous generation of die link charts and network visualizations. While much work remains to complete the digitization of Schaefer's die study, these digital tools reveal patterns more rapidly to a broader audience without the time-consuming data aggregation process that once defined die studies.

description: HIV-1 replication in the central nervous system (CNS) is typically limited by the availability of target cells. HIV-1 variants that are transmitted and dominate the early stages of infection almost exclusively use the CCR5 coreceptor and are well adapted to entering, and thus infecting, cells expressing high CD4 densities similar to those found on CD4+ T cells. While the “immune privileged” CNS is largely devoid of CD4+ T cells, macrophage and microglia are abundant throughout the CNS. These cells likely express CD4 densities that are too low to facilitate efficient entry or allow sustained replication by most HIV-1 isolates. Examination of CNS viral populations reveals that late in disease the CNS of some individuals contains HIV-1 lineages that have evolved the ability to enter cells expressing low levels of CD4 and are well-adapted to entering macrophages. These macrophage-tropic (M-tropic) viruses are able to maintain sustained replication in the CNS for many generations, and their presence is associated with severe neurocognitive impairment. Whether conditions such as pleocytosis are necessary for macrophage-tropic viruses to emerge in the CNS is unknown, and extensive examinations of macrophage-tropic variants have not revealed a genetic signature of this phenotype. It is clear, however, that macrophage tropism is rare among HIV-1 isolates and is not transmitted, but is important due to its pathogenic effects on hosts. Prior to the evolution of macrophage-tropic variants, the viruses that are predominately infecting T cells (R5 T cell-tropic) may infect macrophages at a low level and inefficiently, but this could contribute to the reservoir.

description: Over the course of the American Numismatic Society's Hellenistic Royal Coinages project, nearly 3,000 monogram identifiers were created, each with an open access Screen Vector Graphic image that can be reused on the web and in print. These monogram identifiers have been integrated into the online type corpora of PELLA (the coinages struck in the name of Alexander the Great and Philip Arrhidaeus), Seleucid Coins Online, Ptolemaic Coins Online, and Antigonid Coins Online. The result is that the monograms are linked to more than 10,000 types and subtypes, which are also linked to Nomisma.org concepts for denominations, mints, authorities, etc., enabling the query and visualization of the relationship between these entities and the monograms appearing on associated coinage. This paper introduces the user interfaces built around searching and visualizing monograms, from network graphs to maps depicting the production and circulation of these symbols, and the questions that might be answered.

description: Since the onset of the HIV epidemic, there has been a shift from a deadly diagnosis to the management of a chronic disease. This shift is the result of the development of highly effective drugs that are able to suppress viral replication for years. The availability of these regimens has also shifted the neurocognitive pathology associated with infection from potentially devastating to a much milder phenotype. As the disease outcome has changed significantly with the availability of antiretroviral therapy, there is an opportunity to re-evaluate the currently available models to address the neurocognitive pathology seen in suppressed patients. In the following, we seek to summarize the current literature on humanized mouse models and their utility in understanding how HIV infection leads to changes in the central nervous systems (CNS). Also, we identify some of the unanswered questions regarding HIV infection of the CNS as well as the opportunities and limitations of currently existing models to address those questions. Finally, our conclusions indicate that the earlier humanized models used to study HIV infection in the CNS provided an excellent foundation for the type of work currently being performed using novel humanized mouse models. We also indicate the potential of some humanized mouse models that have not been used as of this time for the analysis of HIV infection in the brain.

description: Secondary stars in cataclysmic variables (CVs) follow a well defined period-density relation. Thus, canonical donor stars in CVs are generally low-mass stars of spectral type M. However, several CVs have been observed containing secondary stars which are too hot for their inferred masses. This particular configuration can be explained if the donor stars in these systems underwent significant nuclear evolution before they reached contact. In this paper we present SDSSJ001153.08-064739.2 as an additional example belonging to this peculiar type of CV and discuss in detail its evolutionary history. We perform spectroscopic and photometric observations and make use of available Catalina Real-Time Transient Survey photometry to measure the orbital period of SDSSJ001153.08-064739.2 as 2.4 hours and estimate the white dwarf (Mwd>0.65Msun) and donor star (0.21Msun

Subsequently we show how this concept is exploited to generate light induced gauge field for neutral ultra cold bosonic atoms. As an example of such light induced Abelian and Non Abelian gauge field for ultra cold atoms we disucss ultra cold atoms in a rotating trap and creation of synthetic spin orbit coupling for ultra cold atomic systems using Raman lasers.

description: Too controversial to discuss only a short time ago, achieving a cure for HIV infection has become a priority in HIV research. However, substantial challenges must be overcome. Among key hurdles to be surmounted is the definition of a reliable, validated model in which to test latency reversal agents (LRAs), as current primary cell models differ in their response to such agents. Animal models such as the HIV-infected humanized BLT mouse and SIV-infected macaque will be essential to study LRAs, and to quantify their effects in anatomic reservoirs. Of several potential anatomic reservoirs, the central nervous system presents a significant obstacle, as it is known to harbor persistent HIV infection, and is difficult to access for study and therapeutic intervention.

description: The classical oscillatory shear wave model of Ferry et al. [J. Polym. Sci. 2:593-611, (1947)] is extended for active linear and nonlinear microrheology. In the Ferry protocol, oscillation and attenuation lengths of the shear wave measured from strobe photographs determine storage and loss moduli at each frequency of plate oscillation. The microliter volumes typical in biology require modifications of experimental method and theory. Microbead tracking replaces strobe photographs. Reflection from the top boundary yields counterpropagating modes which are modeled here for linear and nonlinear viscoelastic constitutive laws. Furthermore, bulk imposed strain is easily controlled, and we explore the onset of normal stress generation and shear thinning using nonlinear viscoelastic models. For this paper, we present the theory, exact linear and nonlinear solutions where possible, and simulation tools more generally. We then illustrate errors in inverse characterization by application of the Ferry formulas, due to both suppression of wave reflection and nonlinearity, even if there were no experimental error. This shear wave method presents an active and nonlinear analog of the two-point microrheology of Crocker et al. [Phys. Rev. Lett. 85: 888 - 891 (2000)]. Nonlocal (spatially extended) deformations and stresses are propagated through a small volume sample, on wavelengths long relative to bead size. The setup is ideal for exploration of nonlinear threshold behavior.

description: A two-component order parameter approach for the layered superconductor is shown to form a condensate with magnetic and charge degrees of freedom. This condensate is an inhomogeneous state, topologically stable, that exists without the presence of an applied magnetic field. We show that the charge density in the layers presents hexadecapole moment in its lowest order. Our approach is based on the first order equations that we show here to solve the variational equations for the special temperature defined by the crossing of the superconducting dome and the pseudogap transition line. Time reversal symmetry is broken and the weak local magnetic field produced by this inhomogeneous state falls below the threshold of experimental observation. We find that the charge distribution in the layers has an hexadecapole moment in its lowest order.

description: This discussion relates to the identification of devices contractual in succession function which can validly be used in the alternative of the will, in the trans-generational transmission of wealth. In this perspective, this essay offers a wide and critical interpretation of those rules of the italian law of succession, particularly the prohibition of succession agreements in art. 458 c.c., which prevent the full unfolding of private autonomy in the field of inheritance law and seem to be in conflict with the deeply changed social system. The essay is first directed to the careful examination of the justifications of the current classic limit of the art. 458 c.c. in Italy and to the comparison with different approach to the succession agreements of the German law, which generally accepts the figure of the so called “Erbvertrag”. The analysis presents some considerations on the limits the of the current structure of the law of succession in Italy and on the technical methods and the evolving interpretation through which the inheritance mechanism becomes viable. The “Family pact” Law wich was recently introduced in the italian legal system as an alternative opportunity to manage the “transfer” of family business, the character of disuse currently assumed by the will and the growing creative commitment of the negotiating practice in perfecting devices contractual in succession function show that Italian law is trying to reorganize itself to meet the needs of a society facing the challenge of trans-generational transfer of property.

description: An extremely weak circularly-polarized signature was recently discovered in spectral lines of the chemically peculiar Am star Sirius A (Petit et al. 2011). This signal was interpreted as a Zeeman signature related to a sub-gauss longitudinal magnetic field, constituting the first detection of a surface magnetic field in an Am star. We present here ultra-deep spectropolarimetric observations of two other bright Am stars, $β$ UMa and $θ$ Leo, observed with the NARVAL spectropolarimeter. The line profiles of the two stars display circularly-polarized signatures similar in shape to the observations gathered for Sirius A. These new detections suggest that very weak magnetic fields may be present in the photospheres of a significant fraction of intermediate-mass stars, although the strongly asymmetric Zeeman signatures measured so far in Am stars (featuring a prominent positive lobe and no detected negative lobe) are not expected in the standard theory of the Zeeman effect.

Diversity in museums: The inclusive value of museum audio description
Creators: name: Bartolini, Chiara
Publisher: name: DIVE-IN – An International Journal on Diversity and Inclusion
Year: 2022

description: This contribution seeks to explore the potential of museum audio description (AD) – a sub-genre of general screen AD – as an instance of intersemiotic translation for non-sighted and sighted alike by drawing on a systematic review of museum AD guidelines and on extensive bibliography from Museum Studies (MS), Translation Studies (TS) and, within the latter, Audiovisual Translation (AVT) and Media Accessibility (MA). The paper will first discuss the social mission of museums and the intrinsic diversity characterising their communication and translation practices, with a special focus on museum AD. It will then move on to the wider value of screen AD; although the latter is primarily intended as an access tool to help blind and visually impaired individuals construct a mental image of what they cannot partially or totally see, its recognised benefits for other groups (Perego 2017) will be addressed. Similarly, the paper will discuss the potential of museum AD for a wider audience by presenting insights from museum-specific AD guidelines. Museum AD may arguably be revisited as a form of museum translation for everybody, which could truly foster social inclusion.

Simultaneous multiple non-crossing quantile regression estimation using kernel constraints

description: Quantile regression (QR) is a very useful statistical tool for learning the relationship between the response variable and covariates. For many applications, one often needs to estimate multiple conditional quantile functions of the response variable given covariates. Although one can estimate multiple quantiles separately, it is of great interest to estimate them simultaneously. One advantage of simultaneous estimation is that multiple quantiles can share strength among them to gain better estimation accuracy than individually estimated quantile functions. Another important advantage of joint estimation is the feasibility of incorporating simultaneous non-crossing constraints of QR functions. In this paper, we propose a new kernel-based multiple QR estimation technique, namely simultaneous non-crossing quantile regression (SNQR). We use kernel representations for QR functions and apply constraints on the kernel coefficients to avoid crossing. Both unregularised and regularised SNQR techniques are considered. Asymptotic properties such as asymptotic normality of linear SNQR and oracle properties of the sparse linear SNQR are developed. Our numerical results demonstrate the competitive performance of our SNQR over the original individual QR estimation.

#Soundwordsmatter: Epistemic modality and evidentiality in Twitter discourse on racism
Creators: name: Borghetti, Claudia
name: Pano Alamán, Ana
Publisher: name: DIVE-IN – An International Journal on Diversity and Inclusion
Year: 2022

description: This paper presents the results of a corpus-based pilot study aiming to investigate whether and to what extent epistemicity and evidentiality contribute to the degree of assertiveness of discourse on Twitter. The analysis was conducted on 900 tweets in English, Italian, and Spanish, published between May and June 2020 after the killing of George Floyd in the USA. We explore the epistemic constructions employed by users to evaluate the object of discourse (racism, discrimination), and their use of evidentials for marking the source of information of their statements. The results show that epistemic markers are not frequent in the corpora, but that in most cases they display high commitment towards the truth of the users’ propositions. As for evidentiality, its presence is even lower, especially in the English dataset. These findings suggest that controversial debates on Twitter favour the adoption of assertive and inferential strategies.

Improving Cooling performance of the mechanical resonator with the two-level-system defects

Year: 2014

description: We study cooling performance of a realistic mechanical resonator containing defects. The normal cooling method through an optomechanical system does not work efficiently due to those defects. We show by employing periodical $σ_z$ pulses, we can eliminate the interaction between defects and their surrounded heat baths up to the first order of time. Compared with the cooling performance of no $σ_z$ pulses case, much better cooling results are obtained. Moreover, this pulse sequence has an ability to improve the cooling performance of the resonator with different defects energy gaps and different defects damping rates.

description: Η εργασία προσφέρει μία θεμελιώδη επισκόπηση της συνεχούς αναπτυσσόμενης βιβλιογραφίας σχετικά με οικονομικά της CBDC. Μελετώνται οι δυνάμεις που οδήγησαν την άνοδο της ψηφιοποίησης του χρήματος, ενώ αναλύονται τα κίνητρα για την έκδοση CBDC. Πραγματοποιείται μία επισκόπηση των χαρακτηριστικών που μπορεί να εμπεριέχει μία CBDC, καθώς επίσης και τους διαθέσιμους αρχιτεκτονικούς σχεδιασμός τόσο για γενική όσο και χονδρική χρήση. Εν συνεχεία, αναλύονται οι επιπτώσεις στη χρηματοπιστωτική σφαίρα και αναφέρονται ζητήματα πολιτικής και προκλήσεων. Ενώ η ακαδημαϊκή βιβλιογραφία ταυτίζεται στην πλειοψηφία των περιπτώσεων με τις ανησυχίες των υπεύθυνων χάραξης πολιτικών, όπως την αποδιαμεσολάβηση των τραπεζών ή τους κινδύνους χρηματοπιστωτικής σταθερότητας, προσφέρει κάποιες ευκαιρίες, που υπό προϋποθέσεις και σωστό σχεδιασμό ενδέχεται να μην εμφανιστούν. Τέλος μελετάται η λύση στο πρόβλημα των διασυνοριακών συναλλαγών, δηλαδή κατά πόσο είναι ικανό ένα σύστημα αποτελούμενο από διασυνδεδεμένες CBDC, με επίπεδο μετατροπής συναλλάγματος, να προσφέρει άμεσες, φθηνές, παγκόσμιες και ασφαλείς συναλλαγές μέσα από ένα ενιαίο σύστημα εκκαθάρισης.
description: This paper provides a fundamental overview of the continuously developing literature on CBDC economics. It studies the forces that have driven the rise of digitalization of money and analyzes the motivations for CBDC issuance. An overview of the features that a CBDC may contain is provided, as well as the available architectural designs for both general and wholesale use. Subsequently, the implications for the financial sphere are analyzed and policy issues and challenges are discussed. While the academic literature identifies in the majority of cases with the concerns of policymakers, such as bank de-intermediation or financial stability risks, it offers some opportunities that, under certain conditions and proper design, may not arise. Finally, it considers the solution to the cross-border trading problem, i.e. whether a system consisting of interconnected CBDCs, with a level of foreign exchange conversion, is capable of providing direct, cheap, global and secure transactions through a single clearing system.

description: The vector meson $ρ$ in the presence of external magnetic field has been investigated in the framework of the Nambu--Jona-Lasinio model, where mesons are constructed by infinite sum of quark-loop chains by using random phase approximation. The $ρ$ meson polarization function is calculated to the leading order of $1/N_c$ expansion. It is found that the constituent quark mass increases with magnetic field, the masses of the neutral vector meson $ρ^{0}$ with spin component $s_z=0,\,\pm1$ and the charged vector meson $ρ^{\pm}$ with $s_z=0$ also increases with magnetic field. However, the mass square of the charged vector meson $ρ^{+}$ ($ρ^{-}$) with $s_z=+1$ ($s_z=-1$) decreases linearly with magnetic field and drops to zero at the critical magnetic field $e B_c \simeq 0.2 {\rm GeV}^2$, which indicates the possible condensation of charged vector meson in the vacuum. This critical magnetic field is much lower than the value $eB_c=0.6 {\rm GeV}^2$ predicted by a point-like vector meson. We also show that if we use lowest Landau level approximation, the mass of the charged vector meson $ρ^{\pm}$ for $s_z=\pm1$ cannot drop to zero at high magnetic fields.

Optimal alignments of longest common subsequences and their path properties

description: We investigate the behavior of optimal alignment paths for homologous (related) and independent random sequences. An alignment between two finite sequences is optimal if it corresponds to the longest common subsequence (LCS). We prove the existence of lowest and highest optimal alignments and study their differences. High differences between the extremal alignments imply the high variety of all optimal alignments. We present several simulations indicating that the homologous (having the same common ancestor) sequences have typically the distance between the extremal alignments of much smaller size than independent sequences. In particular, the simulations suggest that for the homologous sequences, the growth of the distance between the extremal alignments is logarithmical. The main theoretical results of the paper prove that (under some assumptions) this is the case, indeed. The paper suggests that the properties of the optimal alignment paths characterize the relatedness of the sequences.
