description: This paper presents a coordinate free pre-metric formulation of charge free Maxwell-Minkowski electrodynamics, and of the developed by the authors non-linear Extended Electrodynamics. First we introduce some formal relations from multilinear algebra and differential geometry to be used further. Then we recall and appropriately modify the existing pre-metric formulation of linear charge free electrodynamics in pre-relativistic and relativistic forms as preparation to turn to corresponding pre-metric nonlinearization. After some preliminary examples and notes on nonlinearization, we motivate our view for existence and explicit formulation of time stable subsystems of the physical field objects considered. Section 5 presents the formal results of our approach on the pre-metric nonlinear formulations in static case, in time-dependent case, and in space-time formulation. In the Conclusion we give our general view on "why and how to nonlinearize". The Appendix gives a possible formal extension of our aproach to many subsystem field objects.

description: We aim at drawing the hadron-quark phase transition line in the QCD phase diagram by using the two phase model (TPM) in which the entanglement Polyakov-loop extended Nambu--Jona-Lasinio (EPNJL) model with vector-type four-quark interaction is used for the quark phase and the relativistic mean field (RMF) model is for the hadron phase. Reasonable TPM is constructed by using lattice QCD data and neutron star observations as reliable constraints. For the EPNJL model, we determine the strength of vector-type four-quark interaction at zero quark chemical potential from lattice QCD data on quark number density normalized by its Stefan-Boltzmann limit. For the hadron phase, we consider three RMF models, NL3, TM1 and model proposed by Maruyama, Tatsumi, Endo and Chiba (MTEC). We find that MTEC is most consistent with the neutron star observations and TM1 is the second best. Assuming that the hadron-quark phase transition occurs in the core of neutron star, we explore the density-dependence of vector-type four-quark interaction. Particularly for the critical baryon chemical potential at zero temperature, we determine a range for the quark phase to occur in the core of neutron star.

Migrating data without original checksums

Publisher: name: Zenodo
Year: 2024

description: The National Library (NLN) has been using SAM-FS (Oracle HSM) as a bit-repository since 2007. SAM-FS is soon reaching "EOL". The NLN has recently developed a front-end software solution called DPS (Digital Preservation Services). DPS uses HPSS from IBM as underlying bit-repository. DPS/HPSS is intended to replace SAM-FS as the preservation solution for digital objects. DPS requires that all objects must be delivered with associated checksums. 

In the old SAM-FS bit-repository, many objects lack checksums, especially material from the first years of its use. All objects in SAM-FS are stored in 3 instances. If differences were to be uncovered between the 3 instances, there are no checksums to verify which instance is correct. The total amount of data to be migrated from SAM-FS to DPS is approximately 14 Petabytes. It is estimated that about 1/3 of these data lacks checksums. 

Challenge: How could we ensure that objects migrated from SAM-FS to DPS are the same as those originally archived in SAM-FS when original checksums do not exist?
A Tale of Two Women in Two Countries: Suzanne Chantal and Paola Ojetti’s Professional Careers in the Film Press (1930s-mid 1940s)

description: This essay compares the professional experiences of Suzanne Chantal and Paola Ojetti in 1930s France and in 1930s and early-1940s Italy, respectively. Beyond their very different political, national, and cultural contexts, these women both occupied central positions within some of the most influential film periodicals of the era: Suzanne Chantal for Cinémonde and Paola Ojetti for Film. This study is mainly based on sources which enable us to take a closer look at their activities, their working conditions, and their feelings regarding the treatment they received while working for these periodicals. Sources include Suzanne Chantal’s memoirs and her personal diaries from the late 1930s, kept by her family, and Paola Ojetti’s extensive working correspondence, preserved in the Fondo Mino Doletti of the Biblioteca Renzo Renzi at the Cineteca di Bologna, as well as other correspondence documents preserved in Italian archives. This paper explores the working trajectories and social positioning made by these two largely forgotten but powerfully significant figures in order to establish themselves in a predominantly male professional and cultural environment, while at the same time questioning the limits of their integration. By shedding light on microhistory and questioning gender issues, this article turns its attention primarily to working practices, women’s paths, and social networks of film press and film criticism history.

description: We perform a high resolution Fourier Transform Spectroscopy of optical sources in the few-photon regime based on the phenomenon of two-photon interference in a beam splitter. From the heterodyne interferogram between test and reference sources it is possible to obtain the spectrum of the test source relative to that of the reference. The method proves to be a useful asset for spectral characterization of faint optical sources below the range covered by classical heterodyne beating techniques.

description: We study the $(1,0)$ six-dimensional SCFTs living on defects of non-geometric heterotic backgrounds (T-fects) preserving a $E_7\times E_8$ subgroup of $E_8\times E_8$. These configurations can be dualized explicitly to F-theory on elliptic K3-fibered non-compact Calabi-Yau threefolds. We find that the majority of the resulting dual threefolds contain non-resolvable singularities. In those cases in which we can resolve the singularities we explicitly determine the SCFTs living on the defect. We find a form of duality in which distinct defects are described by the same IR fixed point. For instance, we find that a subclass of non-geometric defects are described by the SCFT arising from small heterotic instantons on ADE singularities.

Moreover, the GDGI dataset has the potential to serve as an effective fundamental resource for additional research endeavors within the domain of animal husbandry.
Dynamical impact of the Planet Nine scenario: N-body experiments

description: The Planet Nine hypothesis has now enough constraints to deserve further attention in the form of detailed numerical experiments. The results of such studies can help us improve our understanding of the dynamical effects of such a hypothetical object on the extreme trans-Neptunian objects or ETNOs and perhaps provide additional constraints on the orbit of Planet Nine itself. Here, we present the results of direct N-body calculations including the latest data available on the Planet Nine conjecture. The present-day orbits of the six ETNOs originally linked to the hypothesis are evolved backwards in time and into the future under some plausible incarnations of the hypothesis to investigate if the values of several orbital elements, including the argument of perihelion, remain confined to relatively narrow ranges. We find that a nominal Planet Nine can keep the orbits of (90377) Sedna and 2012 VP113 relatively well confined in orbital parameter space for hundreds of Myr, but it may make the orbits of 2004 VN112, 2007 TG422 and 2013 RF98 very unstable on time-scales of dozens of Myr, turning them retrograde and eventually triggering their ejection from the Solar system. Far more stable orbital evolution is found with slightly modified orbits for Planet Nine.

Guido Aristarco: From Lascia o Raddoppia? to Broadcast Media
Creators: name: Macaluso, Matteo

Year: 2023

description: This paper analyzes various documents from the archive at the library of the Cineteca di Bologna, "Renzo Renzi", which corroborate a professional collaboration between film critic Guido Aristarco and the state-run broadcaster Radiotelevisione Italiana (Rai) for the popular TV show Lascia o raddoppia? in 1956. These materials, including lists of questions about history of cinema, are a resource for recent studies that regard Italian film criticism as a relational system. More precisely, it is yet another in step in the historicization of a high-profile figure like Guido Aristarco and investigates the ways in which Aristarco used broadcast media, which occupied a central position in the media system during this period, as a pace for action within the complex dynamics of modern mass society.

description: This thesis engages in a close reading of the three newsletters produced during the Occupation of Alcatraz Island by the urban Indigenous collective, the Indians of All Tribes (IAT). The Alcatraz Newsletter served as a platform through which the IAT could disseminate their written work, poetry, and art as well as solicit monetary donations to sustain the occupation. As I argue, the IAT use these newsletters to articulate a novel notion of Indigenous self-determination that I conceptualize as “urban autonomy.” Urban autonomy, as a political theory of urban Indigenous self-determination, functions as an alternative to the territorialized notion of tribal sovereignty. While tribal sovereignty is a workable concept to empower and strengthen Indigenous political nations or nation-building projects within reservation lands, urban autonomy is not concerned with Native nationhood. Instead, urban autonomy registers a form of Indigenous diasporic politics and the making of an intertribal urban diasporic political community. My reading of the Alcatraz Newsletters sees the IAT engaged in three distinct forms of Indigenous political criticism. I argue that urban autonomy is activated as a discursive practice within and through this indigenous political criticism.

description: The present study examined the effects of racism on a wide array of health outcomes and explored the role of communal coping and racial centrality on the downstream effects of racism in a sample of college students. We conducted a 7-day daily diary study with 41 non-White college students at Carnegie Mellon University that 1) examined the effect of racism on health, 2)investigated racial centrality as a moderator variable, and 3) examined how communal copingwith racism affects health. It was hypothesized that daily racism and vicarious discrimination would be associated with poorer health outcomes. It was also hypothesized that racial centrality would moderate the relation between racial daily racism and health. Lastly, it was hypothesized that communal coping with a partner in the context of daily racism would be related to better health. Results showed that daily racism was not related to any health outcomes, but that vicarious discrimination was associated with poorer mental and physical health. There was some evidence for racial centrality as a moderator variable. Findings at the day level showed that high racial centrality buffers individuals from the negative effect of daily racism on health. Findings at the person level showed that those who experience more discriminatory events fare better in terms of daily health—especially if they are low in racial centrality. In regard to communal coping, appraising racism as a shared stressor was related to better health and high collaboration buffered individuals from the negative effects of daily racism on mental and physical health. Together these findings suggest that a communal coping framework may be advantageous for minorities when dealing with a stressor such as racism. Thus, future research should continue to investigate the circumstances in which communal coping with daily racism could be helpful.

Antonio Covi: An Institutionalized Militant for the Emergence of Film Culture
Creators: name: Stergar, Steven
Publisher: name: Cinergie – Il Cinema e le altre Arti
Year: 2023

description: Padua, 30s. A young Antonio Covi contributed to making the city’s Film Club possible by playing a crucial role as a cinephile militant amongst public debates, filmmaking experiences, and film critics mainly published in local journals. In less than a decade, he obtained his Literature degree with a dissertation on film aesthetic in 1940, attended then film courses at the Centro Sperimentale di Cinematografia, and, finally, he joined the Jesuits Society in August 1945. The Ignatian confreres immediately acknowledge his aptitude for film and arts, enough for obtaining pivotal roles in Jesuit cultural policies over the years. This step from “militancy” toward “institution” allowed him to embrace national perspectives, establishing him as a reference point for Catholics in film knowledge widespread both in the Fifties and Sixties. During these two decades, father Covi published several articles and essays on film criticism and aesthetics, led the Antonianum Cineforum in Padua and film courses throughout Italy, and ran a local film production company. Film criticism as a form of cultural diplomacy and education represents the thread for all these activities. The paper aims to point out Antonio Covi’s contribution to Italy’s film culture from the 1930s to the 1960s. Firstly, by questioning the shift from “militancy” to “institution” and his role as a film critic during those years. Secondly, by underlying his discourses on film knowledge spread over national and local journals, books, public statements, and film courses as well, proposing, therefore, a diagnostic analysis of terms and themes he dealt with.

Error detection and quality control of citizen science data

Publisher: name: Zenodo
Year: 2023
Subjects: citizen science, data validation, probabilistic reasoning

description: Citizen science (CS) data are a useful source of information that complements traditional data sources. However, CS data typically cannot be used without some level of quality control. This is often done manually, which can become unwieldy for large datasets. Here, a semi-automatic quality control approach was discussed based on quantitative probabilistic modeling of CS data errors. The model that was presented applies probabilistic reasoning to figure out the underlying true value based on one or more CS observations of the same event. The approach was illustrated using a CS dataset of rainfall observations from Nepal. The methodology can however be tailored to other CS datasets as well by adapting the modeling assumptions to the application at hand. The speaker, Dr. Gerrit Schoups is an Assistant Professor in the Water Management department at TU Delft. His current research focuses on probabilistic modeling to quantify uncertainty in hydrological models and to extract information from new data sources like remote sensing and citizen science data.

Where It’s from, Where It Goes: Categorical Retrieval and Comparative Judgments in Spending Small Windfall Income
Creators: name: Chen, Chuanye
Publisher: name: Carnegie Mellon University
Year: 2022
Subjects: subject: 150501 Consumer-Oriented Product or Service Development
subject: FOS: Economics and business

description: The present study proposes that when spending windfall income, consumers categorically retrieve a comparison set from the previous spending with the exact source of income and engage in two comparative judgments: (1) how similar is the target product of the retrieved category and (2) whether the price is acceptable compared to a reference level. In an experiment where participants shop in a hypothetical online store either using a COVIDstimulus check or Cyber Monday Gift Card, where we manipulate the reference price to be either in line with or much lower than the listing price, we show weak albeit significant evidence that a considerable income source effect occurs for electronic items only when the price of the target product is manipulated to look acceptable. The predicted interaction between income source and the reference price level is not significant for non-electronic items. This result cannot be fully accounted for by the differing marginal propensity to consume (MPC) in different mental accounts, and we discuss its theoretical and managerial implications.

description: Liquid-phase transmission electron microscopy is used to study a wide range of chemical processes, where its unique combination of spatial and temporal resolution provides countless insights into nanoscale reaction dynamics. However, achieving sub-nanometer resolution has proved difficult due to limitations in the current liquid cell designs. Here, a novel experimental platform for in situ mixing using a specially developed 2D heterostructure-based liquid cell is presented. The technique facilitates in situ atomic resolution imaging and elemental analysis, with mixing achieved within the immediate viewing area via controllable nanofracture of an atomically thin separation membrane. This novel technique is used to investigate the time evolution of calcium carbonate synthesis, from the earliest stages of nanodroplet precursors to crystalline calcite in a single experiment. The observations provide the first direct visual confirmation of the recently developed liquid-liquid phase separation theory, while the technological advancements open an avenue for many other studies of early stage solution-phase reactions of great interest for both the exploration of fundamental science and developing applications.

description: Abstract: Surface Brightness Fluctuations (SBF) magnitudes have been proved as a potential tool for the study of composite stellar populations in galaxies. In particular, we focus on the detection of metal-poor secondary components in metal-rich dominated early type galaxies. Our current work consists in studying radial profiles of SBFs, hence we study the necessary conditions for the detection of SBF gradients. We show how the detection of SBF radial profiles is possible and its relation with the spatial distribution of the metal-poor small populations. In this manner, we can address how fast the chemical enrichment took place and describe the build up of the galaxy.

description: Gravitational wave astronomy has now left its infancy and has become an important tool for probing the most violent phenomena in our Universe. The LIGO/Virgo-KAGRA collaboration operates ground based detectors which cover the frequency band from 10 Hz to the kHz regime. Meanwhile, the pulsar timing array and the soon to launch LISA mission will cover frequencies below 0.1 Hz, leaving a gap in detectable gravitational wave frequencies. Here we show how a laser interferometer on the moon (LION) gravitational wave detector would be sensitive to frequencies from sub Hz to kHz. We find that the sensitivity curve is such that LION can measure compact binaries with masses between 10 and 100M o˙ at cosmological distances, with redshifts as high as z = 100 and beyond, depending on the spin and the mass ratio of the binaries. LION can detect binaries of compact objects with higher-masses, with very large signal-to-noise ratios (SNRs), help us to understand how supermassive black holes got their colossal masses on the cosmological landscape, and it can observe in detail intermediate-mass ratio inspirals at distances as large as at least 100 Gpc. Compact binaries that never reach the LIGO/Virgo sensitivity band can spend significant amounts of time in the LION band, while sources present in the LISA band can be picked up by the detector and observed until their final merger. Since LION covers the deci-Hertz regime with such large SNRs, it truly achieves the dream of multi messenger astronomy.

description: The presence of strong interactions in a many-body quantum system can lead to a variety of exotic effects. Here we show that even in a comparatively simple setup consisting of a charged impurity in a weakly interacting bosonic medium the competition of length scales gives rise to a highly correlated mesoscopic state. Using quantum Monte Carlo simulations, we unravel its vastly different polaronic properties compared to neutral quantum impurities. Moreover, we identify a transition between the regime amenable to conventional perturbative treatment in the limit of weak atom-ion interactions and a many-body bound state with vanishing quasi-particle residue composed of hundreds of atoms. In order to analyze the structure of the corresponding states, we examine the atom-ion and atom-atom correlation functions which both show nontrivial properties. Our findings are directly relevant to experiments using hybrid atom-ion setups that have recently attained the ultracold regime.

description: Electromagnetically induced gratings (EIG) are created by standing-wave laser field in resonant media. Such gratings can be also created by few-cycle electromagnetic pulses counter-propagating in the medium via coherent Rabi oscillations of atomic inversion. In this case, instantaneous cross-section of the pulses in the medium is not necessary for grating formation. In this paper, we revise our recent results in study of such grating formation and their control by few-cycle pulses coherently propagating in a resonant medium. We demonstrate the grating formation and their control in three-level medium excited by three subcycle THz pulses.

description: To study the Galactic halo we need to rely on intrinsically bright and fair distance indicators. Blue Horizontal Branch (BHB) stars accomplish these requirements but traditionally suffer from high levels of contamination from Blue Stragglers stars in photometric samples. Surveys like Pristine and SkyMapper have demonstrated that colors combining a broad- and a narrow-band filter with central wavelength bluewards 4,000 \AA allow them to build high completeness and purity samples of BHB stars. In this context, the Javalambre Photometric Local Universe Survey (J-PLUS), with a broad- and two custom narrow-band filters (among its 12) having central wavelengths shorter than 4,000 \AA, has released more than 2,000 sq. deg in 2020. In this contribution, we review the latest attempts to study the density profile of the halo, discuss our work in which we used three methods to select BHB stars from J-PLUS DR2, present our estimation of the halo profile, and forecast the expectations for J-PAS and its 56 narrow-band filter system.

Due to the presence of the metal absorption layer, some debris in the form of metal nanoparticles is printed together with bioink microdroplets. In this article, experimental investigations of the amount of metal nanoparticles formed during the laser bioprinting process and transported in bioink microdroplets are performed. As metal absorption layers, Ti films with the thickness in the range of 25–400 nm, produced by magnetron spattering, were applied. Dependences of the volume of bioink microdroplets and the amount of Ti nanoparticles within them on the laser pulse fluence were obtained. It has been experimentally found that practically all nanoparticles remain in the hydrogel layer on the donor slide during bioprinting, with only a small fraction of them transferred within the microdroplet (0.5% to 2.5%). These results are very important for applications of laser bioprinting since the transferred metal nanoparticles can potentially affect living systems. The good news is that the amount of such nanoparticles is very low to produce any negative effect on the printed cells.

description: Fast Radio Bursts are millisecond bursts of radio radiation at frequencies of about 1 GHz, recently discovered in pulsar surveys. They have not yet been definitively identified with any other astronomical object or phenomenon. The bursts are strongly dispersed, indicating passage through a high column density of low density plasma. The most economical interpretation is that this is the interglactic medium, indicating that FRB are at "cosmological" distances with redshifts in the range 0.3--1.3. Their inferred brightness temperatures are as high as $10^{37\,\circ}$K, implying coherent emission by "bunched" charges, as in radio pulsars. I review the astronomical sites, objects and emission processes that have been proposed as the origin of FRB, with particular attention to Soft Gamma Repeaters and giant pulsar pulses.

description: The phenomenon of anapole has attracted considerable attention in the field of metamaterials as a possible realization of radiationless objects. We comprehensively study this phenomenon in the cluster-based systems of dielectric particles by considering conditions of anapole manifestation in both single trimers of disk-shaped particles and metamaterial composed on such trimers. Our analytical approach is based on the multipole decomposition method and the secondary multipole decomposition technique. They allow us to associate the anapole with the multipole moments of the trimer and the separate multipole moments of its constitutive particles. The manifestation of anapole in a two-dimensional metamaterial (metasurface) is confirmed by checking the resonant states in the reflected field as well as from the electromagnetic near-field patterns obtained from the full-wave numerical simulation. It is demonstrated that the anapole excitation in trimers results in the polarization-independent suppression of reflection with the resonant enhancement of local electromagnetic fields in the metasurface. Finally, experimental verification of the theoretical results is presented and discussed.

description: We discuss when the incidence coalgebra of a locally finite preordered set is right co-Frobenius. As a consequence, we obtain that a structural matrix algebra over a field $k$ is Frobenius if and only if it consists, up to a permutation of rows and columns, of diagonal blocks which are full matrix algebras over $k$.
Solvent-mediated isotope effects strongly influence the early stages of calcium carbonate formation: exploring D2O vs. H2O in a combined computational and experimental approach

description: In experimental studies, heavy water (D2O) is employed, e.g., so as to shift the spectroscopic solvent background, but any potential effects of this solvent exchange on reaction pathways are often neglected. While the important role of light water (H2O) during the early stages of calcium carbonate formation has been realized, studies into the actual effects of aqueous solvent exchanges are scarce. Here, we present a combined computational and experimental approach to start to fill this gap. We extended a suitable force field for molecular dynamics (MD) simulations. Experimentally, we utilised advanced titration assays and time-resolved attenuated total reflection Fourier transform infrared (ATR-FTIR) spectroscopy. We find distinct effects in various mixtures of the two aqueous solvents, and in pure H2O or D2O. Disagreements between the computational results and experimental data regarding the stabilities of ion associates might be due to the unexplored role of HDO, or an unprobed complex phase behaviour of the solvent mixtures in the simulations. Altogether, however, our data suggest that calcium carbonate formation might proceed “more classically” in D2O. Also, there are indications for the formation of new structures in amorphous and crystalline calcium carbonates. There is huge potential towards further improving the understanding of mineralization mechanisms by studying solvent-mediated isotope effects, also beyond calcium carbonate. Last, it must be appreciated that H2O and D2O have significant, distinct effects on mineralization mechanisms, and that care has to be taken when experimental data from D2O studies are used, e.g., for the development of H2O-based computer models.

description: In this paper, a part-based technique for real time detection of users' faces on mobile devices is proposed. This method is specifically designed for detecting partially cropped and occluded faces captured using a smartphone's front-facing camera for continuous authentication. The key idea is to detect facial segments in the frame and cluster the results to obtain the region which is most likely to contain a face. Extensive experimentation on a mobile dataset of 50 users shows that our method performs better than many state-of-the-art face detection methods in terms of accuracy and processing speed.

description: For holographic CFT states near the vacuum, entanglement entropies for spatial subsystems can be expressed perturbatively as an expansion in the one-point functions of local operators dual to light bulk fields. Using the connection between quantum Fisher information for CFT states and canonical energy for the dual spacetimes, we describe a general formula for this expansion up to second-order in the one-point functions, for an arbitrary ball-shaped region, extending the first-order result given by the entanglement first law. For two-dimensional CFTs, we use this to derive a completely explicit formula for the second-order contribution to the entanglement entropy from the stress tensor. We show that this stress tensor formula can be reproduced by a direct CFT calculation for states related to the vacuum by a local conformal transformation. This result can also be reproduced via the perturbative solution to a non-linear scalar wave equation on an auxiliary de Sitter spacetime, extending the first-order result in arXiv/1509.00113.

description: The synthesis and crystallographic, thermodynamic and transport properties of single crystalline Rh$_{9}$In$_4$S$_4$ were studied. The resistivity, magnetization and specific heat measurements all clearly indicate bulk superconductivity with a critical temperature, $T_{c}\sim$ 2.25 K. The Sommerfeld coefficient $γ$ and the Debye temperature($\varTheta_{\textrm{D}}$) were found to be 34 mJ mol$^{-1}$ K$^{-2}$ and 217 K respectively. The observed specific heat jump, $ΔC/γT_{c}$ = 1.66, is larger than the expected BCS weak coupling value of 1.43. Ginzburg-Landau (GL) ratio of the low temperature GL-penetration depth, $λ_\text{GL}$$\approx$ 5750Å, to the GL-coherence length, $ξ_\text{GL}$$\approx$ 94Å, is large: $κ$ $\sim$ 60. Furthermore, we observed a peak effect in the resistivity measurement as a function of both temperature and magnetic field.
