description: In many ultrasonic imaging systems, data acquisition and image formation are performed on separate computing devices. Data transmission is becoming a bottleneck, thus, efficient data compression is essential. Compression rates can be improved by considering the fact that many image formation methods rely on approximations of wave-matter interactions, and only use the corresponding part of the data. Tailored data compression could exploit this, but extracting the useful part of the data efficiently is not always trivial. In this work, we tackle this problem using deep neural networks, optimized to preserve the image quality of a particular image formation method. The Delay-And-Sum (DAS) algorithm is examined which is used in reflectivity-based ultrasonic imaging. We propose a novel encoder-decoder architecture with vector quantization and formulate image formation as a network layer for end-to-end training. Experiments demonstrate that our proposed data compression tailored for a specific image formation method obtains significantly better results as opposed to compression agnostic to subsequent imaging. We maintain high image quality at much higher compression rates than the theoretical lossless compression rate derived from the rank of the linear imaging operator. This demonstrates the great potential of deep ultrasonic data compression tailored for a specific image formation method.

description: Among the mechanisms for lattice structural deformation, the electron-phonon interaction mediated Peierls charge-density-wave (CDW) instability in single band low-dimensional systems is perhaps the most ubiquitous. The standard mean-field picture predicts that the CDW transition occurs at all fillings and all values of the electron-phonon coupling $g$ and the adiabaticity parameter $t/ω_0$. Here, we correct the mean-field expression for the Peierls instability condition by showing that the non-interacting static susceptibility, at twice the Fermi momentum, should be replaced by the dynamic one. We derive the Luttinger liquid (LL) to CDW transition condition, {\it exact to second order in a novel blocked perturbative approach}, for the spinless one-dimensional Holstein model in the adiabatic regime. The small parameter is the ratio $g ω_0/t$. We present the phase diagram at non-half-filling by obtaining the surprising result that the CDW occurs in a more restrictive region of a two parameter ($g^2 ω_0/t$ and $t/ω_0$) space than at half-filling.

description: We present a deep learning method for accurately localizing the center of a single corneal reflection (CR) in an eye image. Unlike previous approaches, we use a convolutional neural network (CNN) that was trained solely using simulated data. Using only simulated data has the benefit of completely sidestepping the time-consuming process of manual annotation that is required for supervised training on real eye images. To systematically evaluate the accuracy of our method, we first tested it on images with simulated CRs placed on different backgrounds and embedded in varying levels of noise. Second, we tested the method on high-quality videos captured from real eyes. Our method outperformed state-of-the-art algorithmic methods on real eye images with a 35% reduction in terms of spatial precision, and performed on par with state-of-the-art on simulated images in terms of spatial accuracy.We conclude that our method provides a precise method for CR center localization and provides a solution to the data availability problem which is one of the important common roadblocks in the development of deep learning models for gaze estimation. Due to the superior CR center localization and ease of application, our method has the potential to improve the accuracy and precision of CR-based eye trackers

description: Distributed Digital Twins are designed to enhance the intelligence, predictability, and
optimization of industrial assets by actively engaging, synchronizing, and collaborating with
their physical counterparts, i.e., the systems they model, in near real time. This interoperability
allows for seamless connections between real systems and their virtual counterparts, thereby
facilitating the flow of data while aggregating vital information for comprehensive insights
across large entities. However, the constant exchange of data and dependency on the
information technology and operations technology process integrations in these complex
distributed systems give rise to various cyber-security challenges. These include threats to data,
unauthorized accesses, as well as threats to the integrity and reliability of the digital tools and
the services they offer, among others. In this paper, we discuss the relevant cyber-threats within
distributed Digital Twins ecosystems, which we then analyze while outlining different
strategies to mitigate such threats. As a result, we present key takeaways toward a secure and
reliable Digital Twin platform. Finally, different challenges are raised to highlight the status
quo on the security of Digital Twins and areas for improvement.
Jim Jaarmusch and the American national cinema
Creators: name: Urquhart, Peter
Publisher: name: University of British Columbia
Year: 2009

description: Jim Jarmusch is an American independent film-maker whose work, despite its relative popularity and droll veneer, is consistently contra-Hollywood, thematically, aesthetically, and ideologically. In this thesis, I demonstrate through my close analysis of Jarmusch's four major works to date — Stranger Than Paradise (1984), Down By Law (1986), Mystery Train (1989), and Night on Earth (1991) — that Jarmusch's work should best be regarded beside representative examples of other contra-Hollywood national cinemas, rather than held up against the Hollywood cinema. Ultimately, this thesis argues that Jarmusch's oeuvre is a superlative instance of the American national cinema — ah entity not commonly held to exist. I define the American national cinema as one constituent part (like the French national cinema) of the meta-set of the international art cinema practice, and as this entity is distinguishable from Hollywood, and from other nations' commercial cinemas. In Chapter One, I lay the foundation for the above argument with appeals to various expert sources, especially those concerning concepts of ideology, auteurism, national cinema, and the art cinema as a classifiable mode of film practice. The following four chapters consist of close analyses of Jarmusch's four major works. Chapter Two considers how Jarmusch inverts the stereotypes of dreary communist East and sunny capitalist West in Stranger Than Paradise. The emphasis in Chapter Three is on the "things-are-not-as-theyseem" nature of every American cultural phenomenon raised in Down By Law, and how these reversals illuminate Jarmusch's take on his culture. Chapter Four considers the centrality of the relationship of race to American popular culture which Mystery Train posits. Chapter Five shows how Night on Earth. as a natural outward extension of Jarmusch's thematic and stylistic preoccupations, is designed explicitly as an American art film, as I am using the term here. In chapter six, I briefly recapitulate some of the theoretical and industrial suggestions that I proposed at the outset, weigh them against the evidence presented in the four close analyses, and conclude that a contra-Hollywood American national cinema surely exists, and that Jim Jarmusch's work is its exemplary illustration.

description: The LVD detector, located in the INFN Gran Sasso National Laboratory (Italy), studies supernova neutrinos through the interactions with protons and carbon nuclei in the liquid scintillator and interactions with the iron nuclei of the support structure. We investigate the effect of neutrino oscillations in the signal expected in the LVD detector. The MSW effect has been studied in detail for neutrinos travelling through the collapsing star and the Earth. We show that the expected number of events and their energy spectrum are sensitive to the oscillation parameters, in particular to the mass hierarchy and the value of $θ_{13}$, presently unknown. Finally we discuss the astrophysical uncertainties, showing their importance and comparing it with the effect of neutrino oscillations on the expected signal.

description: Context. Obtaining precise stellar and wind properties and abundance patterns of massive stars is crucial to understanding their nature and interactions with their environments, as well as to constrain their evolutionary paths and end-products. Aims. To enable higher versatility and precision of the complete UV to optical range, we improve our NLTE atmosphere and spectrum synthesis code FASTWIND. We also aim to obtain an advanced description of X-ray emission from wind-embedded shocks. Methods. We include a detailed comoving frame radiative transfer for the essential frequency range, but still apply methods that enable low turnaround times. Results. In most cases, our new results agree excellently with those from the alternative code CMFGEN, both regarding the total radiative acceleration, strategic optical lines, and the UV-range. The agreement regarding NIII4634-4640-4642 has improved, though there are still certain discrepancies, mostly related to line overlap effects in the extreme ultraviolet. In the UV range of our coolest models, we find differences in the predicted depression of the pseudo-continuum, most pronounced around Ly_alpha. The comparison between our new and previous FASTWIND version reveals an almost perfect agreement, except for NV 4603-4619. Using an improved, depth-dependent description for the filling factors of hot, X-ray emitting material, we confirm previous analytic scaling relations with our numerical models. Conclusions. We warn against uncritically relying on transitions, which are strongly affected by direct or indirect line-overlap effects. The predicted UV-continuum depression for the coolest grid-models needs to be checked, both observationally, and regarding the underlying atomic data. Wind lines from "super-ionized" ions such as OVI can, in principle, be used to constrain the distribution of wind-embedded shocks.

description: Extracting single-cell information from microscopy data requires accurate instance-wise segmentations. Obtaining pixel-wise segmentations from microscopy imagery remains a challenging task, especially with the added complexity of microstructured environments. This paper presents a novel dataset for segmenting yeast cells in microstructures. We offer pixel-wise instance segmentation labels for both cells and trap microstructures. In total, we release 493 densely annotated microscopy images. To facilitate a unified comparison between novel segmentation algorithms, we propose a standardized evaluation strategy for our dataset. The aim of the dataset and evaluation strategy is to facilitate the development of new cell segmentation approaches. The dataset is publicly available at https://christophreich1996.github.io/yeast_in_microstructures_dataset/ .

description: In recent years, the intelligence of various parts of the home has become one of the essential features of any modern home. One of these parts is the intelligence lighting system that personalizes the light for each person. This paper proposes an intelligent system based on machine learning that personalizes lighting in the instant future location of a recognized user, inferred by trajectory prediction. Our proposed system consists of the following modules: (I) human detection to detect and localize the person in each given video frame, (II) face recognition to identify the detected person, (III) human tracking to track the person in the sequence of video frames and (IV) trajectory prediction to forecast the future location of the user in the environment using Inverse Reinforcement Learning. The proposed method provides a unique profile for each person, including specifications, face images, and custom lighting settings. This profile is used in the lighting adjustment process. Unlike other methods that consider constant lighting for every person, our system can apply each 'person's desired lighting in terms of color and light intensity without direct user intervention. Therefore, the lighting is adjusted with higher speed and better efficiency. In addition, the predicted trajectory path makes the proposed system apply the desired lighting, creating more pleasant and comfortable conditions for the home residents. In the experimental results, the system applied the desired lighting in an average time of 1.4 seconds from the moment of entry, as well as a performance of 22.1mAp in human detection, 95.12% accuracy in face recognition, 93.3% MDP in human tracking, and 10.80 MinADE20, 18.55 MinFDE20, 15.8 MinADE5 and 30.50 MinFDE5 in trajectory prediction.
Varfarin ile İlişkili İntrakraniyal Kanama Korkusu Gerçek mi?
Creators: name: Erkman SANRI

description: Varfarin endikasyonu olan bir hastada intrakraniyal kanama (İKK) ihtimali yüzünden tedaviden geri durmak hepimizin klinikte yaşadığı bir durum. Endikasyonu olmasına rağmen reçete etmekten erinen Nörologlar, Kardiyologlar ve Acil Tıp hekimleriyle sık sık karşılaşmışsınızdır. Gelin artıları ve eksileriyle bu korku gerçek mi değil mi kanıtlarıyla bir irdeleyelim... Atrial fibrilasyon (AF), mekanik prostetik kapak ve venöz tromboembolizm (VTE) tedavilerinde kullanım endikasyonu olan (3) ve iskemik inme tedavisinde kullanılan varfarinin sebep olduğu İKK riski aslında düşük olup 2000’li yıllardan beri değişmemiştir (1). AF'nin tüm iskemik inmelerin %20'si ve tüm kardiyojenik embolik olayların %50’sinden sorumlu olduğunu biliyoruz, zaten endikasyonun esasını da bu bilgi oluşturuyor. Üstelik varfarin tedavisi alan AF'li hastalarda iskemik inme riski yaklaşık %65 oranında azalıyor ve inme sebebiyle kaybedilen iş gücü, yaratılan bakım maliyetleri ve komplike olup da kaybedilen yaşamları düşünürseniz varfarin vermemek neredeyse hastada bile bile inmeye yol açıyor olduğumuz manasına bile gelebilir (1, 4-5, 8). AHA inme kılavuzu da aynı sebeplerle varfarin kullanımını şiddetle öneriyor. AHA'nın bu net önerisi sayesinde de klinisyenlerin varfarin tercihleri yıllar içinde ciddi şekilde artmış, hatta AF’li hastalarda varfarin kullanımı tedavi kalitesini belirleyici bir faktör olmuş durumda (6). AHA kılavuzunun önerilerini de bir daha hatırlatmakta fayda var: AF’li hastalarda inmeden korunmak için varfarin kullanımı şart. Hedef INR düzeyi de 2.5 (2.0-3.0) olmalı (5). Buraya kadar olan kısım bıçağın keskin olmayan yüzü aslında...

description: We demonstrate the coexistence of pseudospin- and valley-Hall-like edge states in a photonic crystal with $C_{3v}$ symmetry, which is composed of three interlacing triangular sublattices with the same lattice constants. By tuning the geometry of the sublattices, three complete photonic band gaps with nontrivial topology can be created, one of which is due to the band inversion associated with the pseudospin degree of freedom at the $Γ$ point and the other two due to the gapping out of Dirac cones associated with the valley degree of freedom at the $K, K'$ points. The system can support tri-band pseudospin- and valley-momentum locking edge states at properly designed domain-wall interfaces. Furthermore, to demonstrate the novel interplay of the two kinds of edge states in a single configuration, we design a four-channel system, where the unidirectional routing of electromagnetic waves against sharp bends between two routes can be selectively controlled by the pseudospin and valley degrees of freedom. Our work combines the pseudospin and valley degrees of freedom in a single configuration and may provide more flexibility in manipulating electromagnetic waves with promising potential for multiband and multifunctional applications.

description: Microwave impedance microscopy (MIM) has been utilized to directly visualize topological edge states in many quantum materials, from quantum Hall systems to topological insulators, across the GHz regime. While the microwave response for conventional metals and insulators can be accurately quantified using simple lumped-element circuits, the applicability of these classical models to more exotic quantum systems remains limited. In this work, we present a general theoretical framework of the MIM response of arbitrary quantum materials within linear response theory. As a special case, we model the microwave response of topological edge states in a Chern insulator and predict an enhanced MIM response at the crystal boundaries due to collective edge magnetoplasmon (EMP) excitations. The resonance frequency of these plasmonic modes should depend quantitatively on the topological invariant of the Chern insulator state and on the sample's circumference, which highlights their non-local, topological nature. To benchmark our analytical predictions, we experimentally probe the MIM response of quantum anomalous Hall edge states in a Cr-doped (Bi,Sb)2Te3 topological insulator and perform numerical simulations using a classical formulation of the EMP modes based on this realistic tip-sample geometry, both of which yield results consistent with our theoretical picture. We also show how the technique of MIM can be used to quantitatively extract the topological invariant of a Chern insulator, disentangle the signatures of topological versus trivial edge states, and shed light on the microscopic nature of dissipation along the crystal boundaries.

description: Levy flights are known to be optimal search strategies in the particular case of revisitable targets. In the relevant situation of non revisitable targets, we propose an alternative model of bidimensional search processes, which explicitly relies on the widely observed intermittent behavior of foraging animals. We show analytically that intermittent strategies can minimize the search time, and therefore do constitute real optimal strategies. We study two representative modes of target detection, and determine which features of the search time are robust and do not depend on the specific characteristics of detection mechanisms. In particular, both modes lead to a global minimum of the search time as a function of the typical times spent in each state, for the same optimal duration of the ballistic phase. This last quantity could be a universal feature of bidimensional intermittent search strategies.

Microturbulence-mediated route for energetic ion transport and Alfvénic mode intermittency in tokamaks

Subjects: subject: Plasma Physics (physics.plasm-ph)

description: We report on a theoretical discovery of new regimes of Alfvén eigenmode (AE) induced fast ion transport in tokamak plasmas, where microturbulence plays the role of a mediator of fast ion relaxation. Coulomb collisional scattering alone leads to small AE amplitudes and does not reproduce the steady state regimes observed in experiments. We show that in nonlinear regimes the effective pitch angle scattering due to microturbulence can lead to steady state AE amplitude evolution. This indicates a new route for fast ion losses, which is beyond the scenarios described in "Energetic ion transport by microturbulence is insignificant in tokamaks" [D. C. Pace et al., Phys. Plasmas 20 (2013) 056108]. As a result, microturbulence can significantly increase the amplitude of AEs in predictive simulations of burning plasma experiments such as ITER.

description: Superconducting radio frequency (SRF) cavities, which are critical components in many particle accelerators, need to be operated in the Meissner state to avoid strong dissipation from magnetic vortices. For a defect-free superconductor, the maximum attainable magnetic field for operation is set by the superheating field, $B_{\mathrm{sh}}$, which directly depends on the surface current. In heterostructures composed of different superconductors, the current in each layer depends not only on the properties of the individual material, but also on the electromagnetic response of the adjacent layers through boundary conditions at the interfaces. Three prototypical bilayers [$\mathrm{Nb_{1-x}Ti_xN}$(50 nm)/Nb, $\mathrm{Nb_{1-x}Ti_xN}$(80 nm)/Nb, and $\mathrm{Nb_{1-x}Ti_xN}$(160 nm)/Nb] are investigated here by depth-resolved measurements of their Meissner screening profiles using low-energy muon spin rotation (LE-$μ$SR). From fits to a model based on London theory (with appropriate boundary and continuity conditions), a magnetic penetration depth for the thin $\mathrm{Nb_{1-x}Ti_xN}$ layers of $λ_\mathrm{Nb_{1-x}Ti_xN} =$ 182.5(31) nm is found, in good agreement with literature values for the bulk alloy. Using the measured $λ_\mathrm{Nb_{1-x}Ti_xN}$, the maximum vortex-free field, $B_{\mathrm{max}}$, of the superconductor-superconductor (SS) bilayer structure was estimated to be 610(40) mT. The strong suppression of the surface current in the $\mathrm{Nb_{1-x}Ti_xN}$ layer suggests an optimal thickness of $\sim 1.4 λ_{\mathrm{Nb_{1-x}Ti_xN}} =$ 261(14) nm.

description: In order to search for shocks in the very early stage of star formation, we performed single-point surveys of SiO J=1-0, 2-1 and 3-2 lines and the H$_2$CO $2_{12}-1_{11}$ line toward a sample of 100 high-mass starless clump candidates (SCCs) by using the Korean VLBI Network (KVN) 21-m radio telescopes. The detection rates of the SiO J=1-0, 2-1, 3-2 lines and the H$_2$CO line are $31.0\%$, $31.0\%$, $19.5\%$ and $93.0\%$, respectively. Shocks seem to be common in this stage of massive star formation. The widths of the observed SiO lines (full width at zero power (FWZP)) range from 3.4 to 55.1 km s$^{-1}$. A significant fraction ($\sim29\%$) of the detected SiO spectra have broad line widths (FWZP $>20~km~s^{-1}$), which are very likely associated with fast shocks driven by protostellar outflows. This result suggests that about one third of the SiO-detected SCCs are not really starless but protostellar. On the other hand, about 40$\%$ of the detected SiO spectra show narrow line widths (FWZP<10 $km~s^{-1}$) probably associated with low-velocity shocks which are not necessarily protostellar in origin. The estimated SiO column densities are mostly $0.31-4.32\times10^{12}~cm^{-2}$. Comparing the SiO column densities derived from SiO J=1-0 and 2-1 lines, we suggest that the SiO molecules in the SCCs may be in the non-LTE condition. The SiO abundances to H$_2$ are usually $0.20-10.92\times10^{-10}$.

description: Η παρούσα εργασία πραγματεύεται το ζήτημα της πολιτικής εξουσίας και της δημοκρατίας στο έργο του John Locke Δεύτερη Πραγματεία Περί Κυβερνήσεως, καθώς το έργο αυτό αποτελεί την τελική κατάληξη και αποκρυστάλλωση της πολιτικής σκέψης του φιλοσόφου. Αρχικά, γίνεται μια σύντομη αναφορά στην έννοια της φυσικής κατάστασης, στη θεωρία της ιδιοκτησίας και στο ρόλο του χρήματος, καθώς και στη μετάβαση από τη φυσική κατάσταση στην πολιτική κοινωνία μέσω του κοινωνικού συμβολαίου. Παρακάτω, αναλύονται οι θέσεις του φιλοσόφου περί πολιτικής εξουσίας και πολιτικής μεταβολής. Βασικό επίσης σημείο, αποτελεί η θεωρία της δημοκρατίας στο πλαίσιο μια φιλελεύθερης άποψης για την πολιτική. Η ανάγνωση των έργων των C.B. Macpherson, Γ. Πλάγγεση, J. Tully, R. Ashcraft, E.M. Wood, N. Wood, I. Hampsher-Monk, J. Dunn, K. Vaughn, Π. Κιτρομηλίδη και Αιμ. Μεταξόπουλου ήταν ιδιαίτερα χρήσιμη για τη συγγραφή τούτης της εργασίας.
description: The main issue of this paper is the political power and democracy in the work of John Locke Second Treatise on Government, and this project is the final outcome of the political thought of the philosopher. First, it begins with a description of the state of nature , wherein individuals are under no obligation to obey one another but are each themselves judge of what the law of nature requires. It continues with the theory of property, the role of money and the social contract. Next, are analyzed the philosopher’s theory over the political power and the political change. It also covers the representative government and the right of revolution. Meanwhile, a major point in this paper is the theory of democracy through a liberal view . Particularly useful for writing this project was the research in works of C.B. Macpherson, C. Plangesi, J. Tully, R. Ashcraft, E.M. Wood, N. Wood, I. Hampsher-Monk, J. Dunn, K. Vaughn, P.

description: Güncel kılavuzlarda (AHA/ACC/HRS); Mg’un Atriyal Fibrilasyonda (AF) ritim ve/veya hız kontrolü açısından kullanımı ve yararı ile alakalı herhangi bir öneri bulunmamaktadır1. Kılavuzlarda Mg kullanımı ‘Torsades de Pointes’ ile sınırlıdır ki; bu öneri de bilindiği üzere sadece 2 adet gözlemsel çalışmanın ışığında yapılan bir öneridir. Her ne kadar güncel kılavuzlar hızlı ventriküler yanıtlı AF’de (HVYAF) Mg kullanımı ile alakalı öneri yapmasa da, görünen o ki; literatürde konu üzerine birçok çalışma yapılmış. Bunların bazıları acil servislerde, bazıları kardiyoloji servislerinde yapılmış. Yapılan çalışmalar sıklıkla prospektif randomize kontrollü çift kör çalışmalar. Bunlardan bazıları placebo kontrollü, bazıları ise hız kontrolünde geleneksel olarak kullanılan ajanlarla (B-bloker, ca-kanal bloker) yapılmış. 2 adet de metaanaliz mevcut2–10. Yapılmış olan bu çalışmalarda Mg ‘un HVYAF ‘de hız ve ritim kontrolünde etkin olduğu gösterilmiş. Placebo kontrollü birçok çalışmada placebodan daha etkin olduğu, başka hız kontrolü için kullanılan ajanlarla yapılan karşılaştırmalarda ise çoğu zaman en az onlar kadar etkin hatta bazen daha da etkin olduğu gösterilmiş.

description: We discuss the potential use of an algebraic method to compute the value of the solar axial dipole moment at solar minimum, widely considered to be the most reliable precursor of the activity level in the next solar cycle. The method consists of summing up the ultimate contributions of individual active regions to the solar axial dipole moment \revtwo{at the end of the cycle}. A potential limitation of the approach is its dependence on the underlying surface flux transport (SFT) model details. We demonstrate by both analytical and numerical methods that the factor relating the initial and ultimate dipole moment contributions of an active region displays a Gaussian dependence on latitude with parameters that only depend on details of the SFT model through the parameter $η/Δ_u$ where $η$ is supergranular diffusivity and $Δ_u$ is the divergence of the meridional flow on the equator. In a comparison with cycles simulated in the 2$\times$2D dynamo model we further demonstrate that the inaccuracies associated with the algebraic method are minor and the method may be able to reproduce the dipole moment values in a large majority of cycles.

description: While Hopfield networks are known as paradigmatic models for memory storage and retrieval, modern artificial intelligence systems mainly stand on the machine learning paradigm. We show that it is possible to formulate a teacher-student self-supervised learning problem with Boltzmann machines in terms of a suitable generalization of the Hopfield model with structured patterns, where the spin variables are the machine weights and patterns correspond to the training set's examples. We analyze the learning performance by studying the phase diagram in terms of the training set size, the dataset noise and the inference temperature (i.e. the weight regularization). With a small but informative dataset the machine can learn by memorization. With a noisy dataset, an extensive number of examples above a critical threshold is needed. In this regime the memory storage limits of the system becomes an opportunity for the occurrence of a learning regime in which the system can generalize.

A dynamical model for the dusty ring in the Coalsack

description: Lada et al. recently presented a detailed near-infrared extinction map of Globule G2 in the Coalsack molecular cloud complex, showing that this starless core has a well-defined central extinction minimum. We propose a model for G2 in which a rapid increase in external pressure is driving an approximately symmetric compression wave into the core. The rapid increase in external pressure could arise because the core has recently been assimilated by the Coalsack cloud complex, or because the Coalsack has recently been created by two large-scale converging flows. The resulting compression wave has not yet converged on the centre of the core, so there is a central rarefaction. The compression wave has increased the density in the swept-up gas by about a factor of ten, and accelerated it inwards to speeds of order $0.4 {\rm km} {\rm s}^{-1}$. It is shown that even small levels of initial turbulence destroy the ring seen in projection almost completely. In the scenario of strong external compression that we are proposing this implies that the initial turbulent energy in this globule is such that $E_{\rm turb} / E_{\rm grav} \le 2 %$. Protostar formation should occur in about $40,000 {\rm years}$.

description: We present the results of the high-resolution spectroscopy of the FU Orionis-type star V960 Mon. The brightness of V960 Mon decreased continuously after the outburst was detected in 2014 November. During this dimming event, we have carried out medium-resolution spectroscopic monitoring observations and found that the equivalent width of the absorption features showed variations. To further investigate the spectroscopic variations, we conducted a high-resolution spectroscopic observation of V960 Mon with the Subaru Telescope and the High Dispersion Spectrograph on 2018 January 8 and 2020 February 1. By comparing this spectrum with the archival data of the Keck Observatory and the High Resolution Echelle Spectrometer taken between 2014 and 2017, we found that the absorption profiles changed as V960 Mon faded. The line profile of absorption lines such as Fe I and Ca I can be explained by a sum of the spectra of the disk atmosphere and the central star. The model spectrum created to explain the variations of the line profiles suggests that the effective temperature of the central star is $\sim$5500 K, which is comparable to that of the pre-outburst phase with a distance of 1.6 kpc with Gaia. The spectrum also shows that the effective temperature of the disk atmosphere decreased as V960 Mon faded. The variations of the H$α$ and Ca II lines (8498.0 A, 8542.1 A) also show that the V960 Mon spectrum became central-star dominant.

description: The H2 molecule has two nuclear spin isomers, the so-called ortho and para isomers. Nuclear spin conversion (NSC) between these states is forbidden in the gas phase. The energy difference between the lowest ortho and para states is as large as 14.7 meV, corresponding to ~170 K. Therefore, each state of H2 differently affects not only the chemistry but also the macroscopic gas dynamics in space, and thus, the ortho-to-para abundance ratio (OPR) of H2 has significant impacts on various astronomical phenomena. For a long time, the OPR of nascent H2 upon formation on dust grains has been assumed to have a statistical value of three and to gradually equilibrate in the gas phase at the temperature of the circumstances. Recently, NSC of H2 was experimentally revealed to occur on water ice at very low temperatures and thus incorporated into gas-dust chemical models. However, H2 molecules should form well before dust grains are coated by water ice. Information about how the OPR of H2 behaves on bare silicate dust before ice-mantle formation is lacking. Knowing the influence of the OPR of H2 if the OPR changes even on a bare silicate surface within an astronomically meaningful time scale is desirable. We report the first laboratory measurements of NSC of H2 physisorbed on amorphous silicate (Mg2SiO4) at temperatures up to 18 K. The conversion was found to occur very rapidly.
