description: We investigate ultrafast dynamics from photoinduced reflectivity of Sr2RhO4 by using femtosecond near-infrared pulses. We observe a clear temperature-dependent anomaly in its electronic dynamics which slows down below 160 K. In addition, coherent oscillations of the A1g symmetric 5.3-THz phonon exhibit a 90-degree shift in its initial phase across TS, indicating a structural change in octahedral rotation distortions. We propose that octahedral structure in Sr2RhO4 evolves at around TS, and it can influence on the non-equilibrium dynamics of photoinduced carriers as well as real-time phonon responses.

description: We present transport measurements through an electrostatically defined bilayer graphene double quantum dot in the single electron regime. With the help of a back gate, two split gates and two finger gates we are able to control the number of charge carriers on two gate-defined quantum dot independently between zero and five. The high tunability of the device meets requirements to make such a device a suitable building block for spin-qubits. In the single electron regime, we determine interdot tunnel rates on the order of 2~GHz. Both, the interdot tunnel coupling, as well as the capacitive interdot coupling increase with dot occupation, leading to the transition to a single quantum dot. Finite bias magneto-spectroscopy measurements allow to resolve the excited state spectra of the first electrons in the double quantum dot; being in agreement with spin and valley conserving interdot tunneling processes.

description: Quantization of gravity suggests that a finite region of space has a finite number of degrees of freedom or `bits'. What happens to these bits when spacetime expands, as in cosmological evolution? Using gravity/field theory duality we argue that bits `fuse together' when space expands.

description: Applying Machine Learning (ML) techniques to design and optimize computer architectures is a promising research direction. Optimizing the runtime performance of a Network-on-Chip (NoC) necessitates a continuous learning framework. In this work, we demonstrate the promise of applying reinforcement learning (RL) to optimize NoC runtime performance. We present three RL-based methods for learning optimal routing algorithms. The experimental results show the algorithms can successfully learn a near-optimal solution across different environment states. Reproducible Code: github.com/huckiyang/interconnect-routing-gym

description: We report the improved test of frame-dragging, an intriguing phenomenon predicted by Einstein's General Relativity, obtained using 7 years of Satellite Laser Ranging (SLR) data of the satellite LARES (ASI, 2012) and 26 years of SLR data of LAGEOS (NASA, 1976) and LAGEOS 2 (ASI and NASA, 1992). We used the static part and temporal variations of the Earth gravity field obtained by the space geodesy mission GRACE (NASA and DLR) and in particular the static Earth's gravity field model GGM05S augmented by a model for the 7-day temporal variations of the lowest degree Earth spherical harmonics. We used the orbital estimator GEODYN (NASA). We measured frame-dragging to be equal to 0.9910 +/- 0.02, where 1 is the theoretical prediction of General Relativity normalized to its frame-dragging value and +/- 0.02 is the estimated systematic error due to modelling errors in the orbital perturbations, mainly due to the errors in the Earth's gravity field determination. Therefore, our measurement confirms the prediction of General Relativity for frame-dragging with a few percent uncertainty.

description: This paper describes a theoretical comparative study of the antiradical properties of six aromatic compounds namely eugenol (EUG), safrole (SAF), myristicin (MYR), carvacrol (CAR), cinnamaldehyde (CIN), and isoeugenol (ISO) found in antioxidant essential oils. Using density functional theory (DFT) calculations, some structural characteristics such as molecular descriptors, frontier molecular orbitals, and molecular electrostatic potential have been studied. Three main antiradical mechanisms, hydrogen atom transfer (HAT), single electron transfer proton transfer (SETPT, and sequential proton loss electron transfer (SPLET) have been also investigated. In addition, the Gibbs free energies related to the reactions of the studied compounds with two reactive oxidant species (HO• and HOO•) have been computed. Throughout the study, the implicitly of polar and nonpolar solvents (water and benzene) has been taken into account. It was found that EUG, SAF, CIN, and ISO scavenge free radicals by means of a CH bond, while CAR and ISO by means of an OH bond. In the gas and benzene phases, all the studied compounds prefer to undergo HAT mechanism, while in water, SPLET is more favoured for CIN, CAR, and ISO and both HAT and SPLET are possible for EUG, SAF, and MYR. In all the studied mediums, the sequence of the antiradical potential is: MYR ≈ SAF ≈ ISO ≈ EUG > CAR > CIN. This order is in line with the available experimental results.

description: Coherent ranging, also known as frequency-modulated continuous-wave (FMCW) laser based ranging (LIDAR) is currently developed for long range 3D distance and velocimetry in autonomous driving. Its principle is based on mapping distance to frequency, and to simultaneously measure the Doppler shift of reflected light using frequency chirped signals, similar to Sonar or Radar. Yet, despite these advantages, coherent ranging exhibits lower acquisition speed and requires precisely chirped and highly-coherent laser sources, hindering their widespread use and impeding Parallelization, compared to modern time-of-flight (TOF) ranging that use arrays of individual lasers. Here we demonstrate a novel massively parallel coherent LIDAR scheme using a photonic chip-based microcomb. By fast chirping the pump laser in the soliton existence range of a microcomb with amplitudes up to several GHz and sweep rate up to 10 MHz, the soliton pulse stream acquires a rapid change in the underlying carrier waveform, while retaining its pulse-to-pulse repetition rate. As a result, the chirp from a single narrow-linewidth pump laser is simultaneously transferred to all spectral comb teeth of the soliton at once, and allows for true parallelism in FMCW LIDAR. We demonstrate this approach by generating 30 distinct channels, demonstrating both parallel distance and velocity measurements at an equivalent rate of 3 Mpixel/s, with potential to improve sampling rates beyond 150 Mpixel/s and increase the image refresh rate of FMCW LIDAR up to two orders of magnitude without deterioration of eye safety. The present approach, when combined with photonic phase arrays based on nanophotonic gratings, provides a technological basis for compact, massively parallel and ultra-high frame rate coherent LIDAR systems.

description: New Zealand white (NZW) mouse is a mutant strain that has a larval defect in the immune system, and a F1 hybrid between NZW and New Zealand Black mouse spontaneously develops systemic lupus erythematosus (SLE). In meantime, the ablation of superoxide dismutase 1 (Sod1) causes autoimmune haemolytic anaemia, a clinical condition of SLE, in mice with a C57BL/6 background. On the basis of our previous studies, we hypothesised that oxidative stress may trigger this aberrant autoimmunity in NZW mice without crossing with another strain. To validate this, we attempted to establish Sod1−/−/NZW mice but this attempt failed to obtain any objective mouse. The congenic Sod1+/−/NZW male mice were completely infertile because of severe oligozoospermia attributed to a defect in spermatogenesis. The levels of the SOD1 protein were about a half in the testes of the Sod1+/−/NZW mice. Sperm from the Sod1+/−/NZW mice were largely defective and showed quite low fertilising ability in in vitro fertilisation assays. Concomitant with an increase in the oxidatively modified proteins, spermatogenic cells underwent more cell death in the testes of the Sod1+/−/NZW mice compared to those of WT/NZW mice. An examination of immunocompetent cells from Sod1+/−/NZW mice indicated an abnormality in T-cell responses. These collective results suggest that the oxidative stress caused by an SOD1 haploinsufficiency exerts deleterious effects on the testis, either directly on spermatogenic cells or via the destabilisation of the autoimmune response in Sod1+/−/NZW mice.

description: Die Auswirkungen des Klimawandels und der damit verbundene Handlungsdruck stellen Kommunen vor große Herausforderungen. Versiegelte Flächen und fehlende Begrünung beeinträchtigen Mikroklima und Luftqualität negativ. Stadtbäume können wesentlich zur Verbesserung beitragen und spielen daher eine zentrale Rolle in der nachhaltigen Stadtentwicklung. Eine wesentliche Grundlage zur Bewertung von Begrünungspotenzialen bilden aufwändig erhobene Baumkataster. Diese erfassen meist nur Bäume im öffentlichen Raum, während Bäume auf Privatgrundstücken oft unberücksichtigt bleiben. Die flächendeckende, automatisierte Erfassung von Stadtbäumen mittels Fernerkundung ist daher ein aktuelles Forschungsthema. In diesem Beitrag wird ein Baumerkennungsverfahren, das auf LiDAR-Daten, Orthofotos und 3D-Gebäudemodellen basiert, weiterentwickelt und evaluiert. Durch den Einsatz von maschinellem Lernen wurden neue Funktionen für variable Suchfenstergrößen entwickelt, mit denen potenzielle Baumspitzen aus dem Kronenhöhenmodell extrahiert werden. Die Erweiterungen und die Evaluation der Methode erfolgten in einem Testgebiet in Köln mit 1.683 manuell erfassten Bäumen. Die Güte der Methode wurde anhand stichprobenunabhängiger Metriken bewertet. Insgesamt konnte die Genauigkeit der automatischen Baumkronenerkennung sowie die Schätzung des darin gespeicherten CO2 auf Siedlungs- und Verkehrsflächen verbessert werden. Dennoch besteht weiterer Forschungs- und Entwicklungsbedarf in der automatisierten und exakten Baumerkennung.

description: We apply the concept of reflection-transmission (RT) algebra, originally developed in the context of integrable systems in 1+1 space-time dimensions, to the study of finite temperature quantum field theory with impurities in higher dimensions. We consider a scalar field in $(s+1)+1$ space-time dimensions, interacting with impurities localized on $s$-dimensional hyperplanes, but without self-interaction. We discuss first the case $s=0$ and extend afterwards all results to $s>0$. Constructing the Gibbs state over an appropriate RT algebra, we derive the energy density at finite temperature and establish the correction to the Stefan-Boltzmann law generated by the impurity. The contribution of the impurity bound states is taken into account. The charge density profiles for various impurities are also investigated.

Transition from eyeball to snowball driven by sea-ice drift on tidally locked terrestrial planets

description: Tidally locked terrestrial planets around low-mass stars are the prime targets for future atmospheric characterizations of potentially habitable systems, especially the three nearby ones--Proxima b, TRAPPIST-1e, and LHS 1140b. Previous studies suggest that if these planets have surface ocean they would be in an eyeball-like climate state: ice-free in the vicinity of the substellar point and ice-covered in the rest regions. However, an important component of the climate system--sea ice dynamics has not been well studied in previous studies. A fundamental question is: would the open ocean be stable against a globally ice-covered snowball state? Here we show that sea-ice drift cools the ocean's surface when the ice flows to the warmer substellar region and melts through absorbing heat from the ocean and the overlying air. As a result, the open ocean shrinks and can even disappear when atmospheric greenhouse gases are not much more abundant than on Earth, turning the planet into a snowball state. This occurs for both synchronous rotation and spin-orbit resonances (such as 3 to 2). These results suggest that sea-ice drift strongly reduces the open ocean area and can significantly impact the habitability of tidally locked planets.

description: A recently proposed method for the characterization and analysis of local equilibrium states in relativistic quantum field theory is applied to a simple model. Within this model states are identified which are locally (but not globally) in thermal equilibrium and it is shown that their local thermal properties evolve according to macroscopic equations. The largest space-time regions in which local equilibrium states can exist are timelike cones. Thus, although the model does not describe dissipative effects, such states fix in a natural manner a time direction. Moreover, generically they determine a distinguished space-time point where a singularity in the temperature (a hot bang) must have occurred if local equilibrium prevailed thereafter. The results illustrate how the breaking of the time reflection symmetry at macroscopic scales manifests itself in a microscopic setting.

description: Recent ARPES measurements on the electron-doped cuprate Nd_{2-x}Ce_xCuO_4 can be interpreted in a mean field model of uniform doping of an antiferromagnet, with the Mott gap closing near optimal doping. Mode coupling calculations confirm the mean field results, while clarifying the relation between the Mott gap and short-range magnetic order. The same calculations find that hole doped cuprates should follow a strikingly different doping dependence, involving instability toward spiral phases or stripes. Nevertheless, the magnetic order (now associated with stripes) again collapses near optimal doping.

description: We show the connection between the extended center of the quantum group in roots of unity and the restriction of the $XXZ$ model. We also give explicit expressions for operators that respect the restriction and act on the state space of the restricted models. The formulas for these operators are verified by explicit calculation for third-degree roots; they are conjectured to hold in the general case.

description: We have investigated the formation and kinematics of sub-mm continuum cores in the Orion A molecular cloud. A comparison between sub-mm continuum and near infrared extinction shows a continuum core detection threshold of $A_V\sim$ 5-10 mag. The threshold is similar to the star formation extinction threshold of $A_V\sim$ 7 mag proposed by recent work, suggesting a universal star formation extinction threshold among clouds within 500 pc to the Sun. A comparison between the Orion A cloud and a massive infrared dark cloud G28.37+0.07 indicates that Orion A produces more dense gas within the extinction range 15 mag $\lesssim A_V \lesssim$ 60 mag. Using data from the CARMA-NRO Orion Survey, we find that dense cores in the integral-shaped filament (ISF) show sub-sonic core-to-envelope velocity dispersion that is significantly less than the local envelope line dispersion, similar to what has been found in nearby clouds. Dynamical analysis indicates that the cores are bound to the ISF. An oscillatory core-to-envelope motion is detected along the ISF. Its origin is to be further explored.

description: Genus Rafapicobia Skoracki
Remark. Up to now, the genus Rafapicobia has included five species described from birds of the orders Passeriformes (Furnariidae, Mimidae, Muscicapidae) (4 species) and Gruiformes (Rallidae) (1) (Skoracki et al. 2014). Gradually increasing the number of known species in this genus makes the previous diagnosis (Skoracki 2011) is no longer sufficient. It mainly concerns such characters as the hypostomal apex shape (which is tapering), hysteronotal shields (present or absent), presence of small thorn-like protuberances on apodemes I (present or absent) and the presence of 3 pairs of aggenital setae and 1 pair of genital setae. Homology of setae ag2 and g seems to be unclear. In females of R. zirnitra Skoracki and R. toxostoma Sikora, Fajfer andt Skoracki homology of setae ag2 does not rise doubts, whilst in R. melzeri Skoracki, Unsoeld, Skorupski and Kavetska, R. dendrocaptesi Skoracki and Solarczyk and R. lepidocolaptesi Skoracki and Solarczyk, R. thamnophili sp. nov., and R. milenskyi sp. nov. arrangement of setae ag2, their thickness and length suggest they are rather genital than aggenital setae.

Strong Gravitational Lensing and Dynamical Dark Energy

Year: 2004
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: We study the strong gravitational lensing properties of galaxy clusters obtained from N-body simulations with different kind of Dark Energy (DE). We consider both dynamical DE, due to a scalar field self--interacting through Ratra-Peebles (RP) or SUGRA potentials, and DE with constant negative w=p/rho= -1 (LCDM). We have 12 high resolution lensing systems for each cosmological model with a mass greater than 5x10^{14} solar masses. Using a Ray Shooting technique we make a detailed analysis of the lensing properties of these clusters with particular attention to the number of arcs and their properties (magnification, length and width). We found that the number of giant arcs produced by galaxy clusters changes in a considerable way from LCDM models to Dynamical Dark Energy models with a RP or SUGRA potentials. These differences originate from the different epochs of cluster formation and from the non-linearity of the strong lensing effect. We suggest the Strong lensing is one of the best tool to discriminate among different kind of Dark Energy.

description: Changes of the magnetic and crystal structure on the microscopic scale in 40 nm FeRh thin films have been applied to investigate the phenomena of a disorder induced ferromagnetism at room temperature initiated through light ion-irradiation with fluences up to 0.125 Ne$^+$/nm$^{-2}$. Magnetometry shows an increase of magnetic ordering at low temperatures and a decrease of the transition temperature combined with a broadening of the hysteresis with rising ion fluence. $^{57}$Fe Mössbauer spectroscopy reveals the occurrence of an additional magnetic contributions with an hyperfine splitting of 27.2 T - identical to that of ferromagnetic B2-FeRh. The appearance of an anti-site Fe-contribution can be assumed to be lower than 0.6 Fe-at%, indicating that no change of the chemical composition is evident. The investigation of the local structure shows an increase of the static mean square relative displacement determined by X-ray absorption fine structure spectroscopy, while an increase of the defect-concentration has been determined by positron annihilation spectroscopy. From the changes of the microscopic magnetic structure a similarity between the temperature induced and the structural disorder induced ferromagnetic phase can be observed. These findings emphasize the relationship between magnetic ordering and the microscopic defect structure in FeRh.

title: The Global Popularity of William Shakespeare in 303 Wikipedias
Creators: name: Blakesley, Jacob
Publisher: name: Memoria di Shakespeare. A Journal of Shakespearean Studies
Year: 2018

description: There are no reliable figures on contemporary Shakespeare reception around the world. However, we can provide such figures by analysing which of the 303 global Wikipedias (in about as many languages) have Shakespeare entries and how often these entries have been viewed. These statistics enable us to concretely identify which works are the most viewed in different contexts around the world. We will see, for instance, which cultures are more interested in Shakespeare’s tragedies, comedies, histories, and poetry. We will find out which single plays are preferred in different cultures, and which plays, instead, are practically ignored abroad. In short, we can distinguish different levels of popularity of his works in different settings. Thus, we will discover that for a plurality of Wikipedias, almost fifty, Romeo and Juliet is number one in pageviews, while in many, but fewer others, it is Hamlet. In seven Wikipedias, on the other hand, Macbeth is number one, while Julius Caesar is first in still several others. Othello, King Lear, A Midsummer Night’s Dream, As You Like It, and Antony and Cleopatra are the only other rare leaders in specific Wikipedias. In short, this article will present the basic popular global reception information about all of Shakespeare’s works, filling a lacuna in critical research; this will allow researchers to pursue more detailed levels of investigation of Shakespeare’s canonicity in different contexts across the globe.

description: In this paper, we explicitly construct a series of projectors on integral noncommutative orbifold $T^2/Z_4$ by extended $GHS$ constrution. They include integration of two arbitary functions with $Z_4$ symmetry. Our expressions possess manifest $Z_{4}$ symmetry. It is proved that the expression include all projectors with minimal trace and in their standard expansions, the eigen value functions of coefficient operators are continuous with respect to the arguments $k$ and $q$. Based on the integral expression, we alternately show the derivative expression in terms of the similar kernal to the integral one.Since projectors correspond to soliton solutions of the field theory on the noncommutative orbifold, we thus present a series of corresponding solitons.

description: Layered van der Waals (vdW) crystals with intrinsic magnetic properties such as high Curie temperature (TC) and large perpendicular magnetic anisotropy (PMA) are key to the development and application of spintronic devices. The ferromagnetic vdW metal Fe3-xGeTe2 (FGT) has gained prominence recently due to its high TC (220 K) and strong PMA. Here, we introduce a new metallic vdW ferromagnets, Fe5-xGe2Te2 or FG2T, which was successfully synthesized and fully characterized. FG2T is a metal that orders ferromagnetically with a very sharp transition at 250 K (bulk and single crystal thin flakes) and shows large PMA, as found by both experimental and computational studies. This work enables novel heterostructure devices with near room temperature capabilities by using FG2T as spin injector.
