description: Detailed behaviors of the modes of quantized scalar fields in the Unruh state for various eternal black holes in two dimensions are investigated. It is shown that the late-time behaviors of some of the modes of the quantum fields and of the symmetric two-point function are determined by infrared effects. The nature of these effects depends upon whether there is an effective potential in the mode equation and what form this potential takes. Here, three cases are considered, one with no potential and two with potentials that are nonnegative everywhere and are zero on the event horizon of the black hole and zero at either infinity or the cosmological horizon. Specifically, the potentials are a delta function potential and the potential that occurs for a massive scalar field in Schwarzschild-de Sitter spacetime. In both cases, scattering effects remove infrared divergences in the mode functions that would otherwise arise from the normalization process. When such infrared divergences are removed, it is found that the modes that are positive frequency with respect to the Kruskal time on the past black hole horizon approach zero in the limit that the radial coordinate is fixed and the time coordinate goes to infinity. In contrast, when there is no potential and thus infrared divergences occur, the same modes approach nonzero constant values in the late-time limit when the radial coordinate is held fixed. The behavior of the symmetric two-point function when the field is in the Unruh state is investigated for the case of a delta function potential in certain asymptotically flat black hole spacetimes in two dimensions. The removal of the infrared divergences in the mode functions results in the elimination of terms that grow linearly in time.

description: Multi-photon and quantum communication experiments such as loophole-free Bell tests and device independent quantum key distribution require entangled photon sources which display high coupling efficiency. In this paper we put forward a simple quantum theoretical model which allows the experimenter to design a source with high pair coupling efficiency. In particular we apply this approach to a situation where high coupling has not been previously obtained: we demonstrate a symmetric coupling efficiency of more than 80% in a highly frequency non-degenerate configuration. Furthermore, we demonstrate this technique in a broad range of configurations, i.e. in continuous wave and pulsed pump regimes, and for different nonlinear crystals.

description: The Earth’s climate system is driven by a complex interplay of internal chaotic dynamics and natural and anthropogenic external forcing. Recent instrumental data have shown a remarkable degree of asynchronicity between Northern Hemisphere and Southern Hemisphere temperature fluctuations, thereby questioning the relative importance of internal versus external drivers of past as well as future climate variability. However, large-scale temperature reconstructions for the past millennium have focused on the Northern Hemisphere, limiting empirical assessments of inter-hemispheric variability on multi-decadal to centennial timescales. Here, we introduce a new millennial ensemble reconstruction of annually resolved temperature variations for the Southern Hemisphere based on an unprecedented network of terrestrial and oceanic palaeoclimate proxy records. In conjunction with an independent Northern Hemisphere temperature reconstruction ensemble, this record reveals an extended cold period (1594–1677) in both hemispheres but no globally coherent warm phase during the pre-industrial (1000–1850) era. The current (post-1974) warm phase is the only period of the past millennium where both hemispheres are likely to have experienced contemporaneous warm extremes. Our analysis of inter-hemispheric temperature variability in an ensemble of climate model simulations for the past millennium suggests that models tend to overemphasize Northern Hemisphere–Southern Hemisphere synchronicity by underestimating the role of internal ocean–atmosphere dynamics, particularly in the ocean-dominated Southern Hemisphere. Our results imply that climate system predictability on decadal to century timescales may be lower than expected based on assessments of external climate forcing and Northern Hemisphere temperature variations alone.

REMARKS: Rondani (1857: 63) described Merodon submetallicus from just the male sex, without specifying the exact number of specimens and not giving a range of lengths, from material received from Germany and L. Bellardi. We could not locate any type specimens during this study. Not included in the type series are a MZUF male and a MSNC male from “Apenn. [= Apennines]” because it is not the type locality, a female because of its sex, a MZUF male numbered “63” dated “1869”, which is subsequent to the original description, and a MSNC specimen because it is not from the type locality.

description: We find third-power nonlinear corrections to the Coulomb and other static electric fields, as well as to the electric and magnetic dipole fields, as we work within QED with no background field. The nonlinear response function we base our consideration on is the fourth-rank polarization tensor, calculated within the local (infrared) approximation of the effective action. Therefore, the results are applicable to weakly varying fields. It is established that the nonlinear correction to magnetic moment of some baryons just matches, in the order of magnitude, the existing gap between its experimental and theoretical values.

description: Author summary: Synchronization of neuronal spiking in the brain is related to cognitive functions, such as perception, attention, and memory. It is therefore important to determine which properties of neurons influence their collective behavior in a network and to understand how. A prominent feature of many cortical neurons is spike frequency adaptation, which is caused by slow transmembrane currents. We investigated how these adaptation currents affect the synchronization tendency of coupled model neurons. Using the efficient adaptive exponential integrate-and-fire (aEIF) model and a biophysically detailed neuron model for validation, we found that increased adaptation currents promote synchronization of coupled excitatory neurons at lower spike frequencies, as long as the conduction delays between the neurons are negligible. Inhibitory neurons on the other hand synchronize in presence of conduction delays, with or without adaptation currents. Our results emphasize the utility of the aEIF model for computational studies of neuronal network dynamics. We conclude that adaptation currents provide a mechanism to generate low frequency oscillations in local populations of excitatory neurons, while faster rhythms seem to be caused by inhibition rather than excitation.

description: We adopt the quark pair creation model to investigate the light meson emissions of several charmonium-like states. The quark pair creation model is applied to the four-body systems, and we calculate the pion/kaon emissions of the $X(4700)$, $Z_c(4430)$, $Y(4230)$, $Y(4360)$, $Y(4390)$ and $Y(4660)$ within the compact tetraquark assumptions. It is found that the pion/kaon decay widths for the $X(4700)$ and $Z_c(4430)$ are relatively small, while the partial decay widths for the resonances $Y(4230)$, $Y(4360)$, $Y(4390)$ and $Y(4660)$ are significant. We expect that our exploration of these decay behaviors can provide useful information for future experimental searches and theoretical interpretations.

TYPE LOCALITY: “ Galliae [= France]” (Fabricius 1805: 239) [type locality for Merodon narcissi (Fabricius, 1805)].
TYPE MATERIAL: see Remarks.
CURRENT STATUS: junior synonym of Merodon equestris (Fabricius, 1794) (Peck 1988: 170).
REMARKS: Rondani (1845f: 256) considered the males of Merodon narcissi (Fabricius, 1805) and the females of Merodon constans Wiedemann, 1822 and Merodon ferrugineus (Fabricius, 1805) as the same species but, instead of applying the Principle of Priority, he incorrectly proposed the substitute name Merodon tuberculatus. Rondani (1865c: 207) used Merodon tuberculatus as a valid species and he (Rondani 1857: 61) reaffirmed having proposed Merodon tuberculatus to combine Merodon narcissi, Merodon constans and Merodon flavicans (Fabricius, 1794). Schiner (1860: 344, 1864: 108), Bezzi & Stein (1907: 121), Kertész (1910: 280), Sack (1931: 314) placed it in synonymy with Merodon equestris (Fabricius, 1794) while Bezzi (1894: 283) considered it to be a valid species. The type material for Merodon tuberculatus will be the same as for the name it was proposed to replace, i. e., Merodon narcissi. There is no type of Merodon narcissi in the ZMUC where Fabricius’s collection is preserved (Michelsen 2017).

description: In this paper, a key problem of the rigorous formulation of the renormalization group as a continuous flow is identified. Some essential features of the operator-theoretic renormalization group are recalled, and a family of norms associated to different Banach spaces of Hamiltonians is introduced. From this, three different properties, which should be satisfied by an adequate norm, are derived, e.g., a submultiplicativity with respect to Wick-ordering. A proof is given that none of the norms introduced in this paper satisfy all of these conditions.

description: Collective motions of epithelial cells are essential for morphogenesis. Tissues elongate, contract, flow, and oscillate, thus sculpting embryos. These tissue level dynamics are known, but the physical mechanisms at the cellular level are unclear. Here, we demonstrate that a single epithelial monolayer of MDCK cells can exhibit two types of local tissue kinematics, pulsations and long range coherent flows, characterized by using quantitative live imaging. We report that these motions can be controlled with internal and external cues such as specific inhibitors and substrate friction modulation. We demonstrate the associated mechanisms with a unified vertex model. When cell velocity alignment and random diffusion of cell polarization are comparable, a pulsatile flow emerges whereas tissue undergoes long-range flows when velocity alignment dominates which is consistent with cytoskeletal dynamics measurements. We propose that environmental friction, acto-myosin distributions, and cell polarization kinetics are important in regulating dynamics of tissue morphogenesis.

description: The calculation of pair correlations and density profiles of quasiholes are routine steps in the study of proposed fractional quantum Hall states. Nevertheless, the field has not adopted a standard way to present the results of such calculations in an easily reproducible form. We develop a polynomial expansion that allows for easy quantitative comparison between different candidate wavefunctions, as well as reliable scaling of correlation and quasihole profiles to the thermodynamic limit. We start from the well-known expansion introduced by Girvin [PRB, 30 (1984)] (see also [Girvin, MacDonald and Platzman, PRB, 33 (1986)]), which is physically appealing but, as we demonstrate, numerically unstable.0 We orthogonalize their basis set to obtain a new basis of modified Jacobi polynomials, whose coefficients can be stably calculated. We then apply our expansion to extract pair correlation expansion coefficients and quasihole profiles in the thermodynamic limit for a wide range of fractional quantum Hall wavefunctions. These include the Laughlin series, composite fermion states with both reverse and direct flux attachment, the Moore-Read Pfaffian state, and BS hierarchy states. The expansion procedure works for both abelian and non-abelian quasiholes, even when the density at the core is not zero. We find that the expansion coefficients for all quantum Hall states considered can be fit remarkably well using a cosine oscillation with exponentially decaying amplitude. The frequency and the decay length are related in an intuitive, but not elementary way to the filling fraction. Different states at the same filling fraction can have distinct values for these parameters. Finally, we also use our scaled correlation functions to calculate estimates for the magneto-roton gaps of the various states.

description: The HELIPORT project aims to make the components or steps of the entire life cycle of a research project at the Helmholtz-Zentrum Dresden-Rossendorf (HZDR) and the Helmholtz-Institute Jena (HIJ) discoverable, accessible, interoperable and reusable according to the FAIR principles. In particular, this data management solution deals with the entire lifecycle of research experiments, starting with the generation of the first digital objects, the workflows carried out and the actual publication of research results. For this purpose, a concept was developed that identifies the different systems involved and their connections. By integrating computational workflows (CWL and others), HELIPORT can automate calculations that work with metadata from different internal systems (application management, Labbook, GitLab, and further). This presentation will cover the first year of the project, the current status and the path taken so far in the life cycle of the project.

description: The effect of an a priori known 3-D crustal model in teleseismic tomography of upper-mantle structure is investigated. We developed a 3-D crustal P-wave velocity model for the greater Alpine region, encompassing the central and western Alps and the northern Apennines, to estimate the crustal contribution to teleseismic traveltimes. The model is constructed by comparative use of published information from active and passive seismic surveys. The model components are chosen to represent the present large-scale Alpine crustal structure and for their significant effect on the propagation of seismic wavefields. They are first-order structures such as the crust–mantle boundary, sedimentary basins and the high-velocity Ivrea body. Teleseismic traveltime residuals are calculated for a realistic distribution of azimuths and distances by coupling a finite-difference technique to the IASP91 traveltime tables. Residuals are produced for a synthetic upper-mantle model featuring two slab structures and the 3-D crustal model on top of it. The crustal model produces traveltime residuals in the range between −0.7 and 1.5 s that vary strongly as a function of backazimuth and epicentral distance. We find that the non-linear inversion of the synthetic residuals without correcting for the 3-D crustal structure erroneously maps the crustal anomalies into the upper mantle. Correction of the residuals for crustal structure before inversion properly recovers the synthetic slab structures placed in the upper mantle. We conclude that with the increasing amount of high-quality seismic traveltime data, correction for near-surface structure is essential for increasing resolution in tomographic images of upper-mantle structure.

description: We model chaotic diffusion, in a symplectic 4D map by using the result of a theorem that was developed for stochastically perturbed integrable Hamiltonian systems. We explicitly consider a map defined by a free rotator (FR) coupled to a standard map (SM). We focus in the diffusion process in the action, $I$, of the FR, obtaining a semi--numerical method to compute the diffusion coefficient. We study two cases corresponding to a thick and a thin chaotic layer in the SM phase space and we discuss a related conjecture stated in the past. In the first case the numerically computed probability density function for the action $I$ is well interpolated by the solution of a Fokker-Planck (F-P) equation, whereas it presents a non--constant time delay respect to the concomitant F-P solution in the second case suggesting the presence of an anomalous diffusion time scale. The explicit calculation of a diffusion coefficient for a 4D symplectic map can be useful to understand the slow diffusion observed in Celestial Mechanics and Accelerator Physics.

description: In this paper, we study different kinds of normal properties for infinite system of arbitrarily many convex sets in a Banach space and provide the dual characterization for the normal property in terms of the extended Jamenson property for arbitrarily many weak*-closed convex cones in the dual space. Then, we use the normal property and the extended Jamenson property to study CHIP, strong CHIP and linear regularity for the infinite case of arbitrarily many convex sets and establish equivalent relationship among these properties. In particular, we extend main results in [3] on normal property, Jamenson property, CHIP and linear regularity for finite system of convex sets in a Hilbert space to the infinite case of arbitrarily many convex sets in Banach space setting.

description: Ultrastrong light-matter coupling opens exciting possibilities to generate squeezed quantum states and entanglement. Here we propose a way to achieve this regime in superconducting hybrid nanostructures with ferromagnetic interlayers. Strong confinement of electromagnetic field between superconducting plates is found to result in the existence of magnon-polariton modes with ultrastrong magnon-photon coupling, ultra-high cooperativity and very large group velocities. These modes provide a numerically accurate explanation of recent experiments and have intriguing quantum properties. The magnon-polariton quantum vacuum consists of the squeezed magnon and photon states with the degree of squeezing controlled in wide limits by the external magnetic field. The ground state population of virtual photons and magnons is shown to be very large which can be used for generating correlated magnon and photon pairs. Excited states of magnon-polaritons contain bipartite entanglement between magnons and photons. This property can be used for transferring entanglement between different types of quantum systems.

description: Power consumption has emerged as a primary design constraint for integrated circuits (ICs). In the Nano meter technology regime, leakage power has become a major component of total power. Full adder is the basic functional unit of an ALU. The power consumption of a processor is lowered by lowering the power consumption of an ALU, and the power consumption of an ALU can be lowered by lowering the power consumption of Full adder. So the full adder designs with low power characteristics are becoming more popular these days. This proposed work illustrates the design of the low-power less transistor full adder designs using cadence tool and virtuoso platform, the entire simulations have been done on 180nm single n-well CMOS bulk technology, in virtuoso platform of cadence tool with the supply voltage 1.8V and frequency of 100MHz. These circuits consume less power with maximum (6T design)of 93.1% power saving compare to conventional 28T design and 80.2% power saving compare to SERF design without much delay degradation. The proposed circuit exploits the advantage of GDI technique and pass transistor logic

description: In this paper, we present the time alignment process to match the dynamics of human signing with the scripted sign (avatar). We replace the manual editing process with a Kinect-based approach. While the current state of the art in sign language recognition does not allow reliable recognition of fluent signing, we will show that it is possible to extract the dynamics of the user’s sign performance and apply it to a pre-existing sign script featuring the exact same signs. The user manually defines a sign script and then signs it into the Kinect for the system to get the dynamics as performed by the user. A dataset of selected signs have been created for the experimentation purpose with the proposed approach and our approach’s performance analysis has been described in detail in this paper.

CURRENT STATUS: valid species, as Spilomyia digitata (Peck 1988: 213, Belcari et al. 1995a: 18, Steenis 2000: 147).
REMARKS: Rondani (1865a: 132) described Milesia digitata from just the male sex, without specifying either the number or the length of the specimens. Steenis (2000: 147) incorrectly stated that Rondani described both sexes of Spilomyia digitata and designated a lectotype (♂) and paralectotypes (1 ♂, 2 ♀♀) in the MZUF. He did not mention an additional male in the OUMNH (this additional specimen is a paralectotype). The two MZUF females numbered “94”, and considered by Steenis (2000: 147) as paralectotypes, do not belong to the type series because of their sex.

description: After the discovery of a Higgs-like boson with a mass of m~125 GeV at the LHC, we can now attempt to draw conclusions about physics beyond the Standard Model. I argue that there are several hints towards new physics at intermediate scales > 10^8 GeV. I review a class of stringy models with intermediate scale SUSY which relate the observed Higgs mass to symmetries of the Higgs sector. I then discuss radiative corrections to m_h, unification, dark matter and the possibility of classically unstable UV completions in these models.

description: High-precision relocations of intermediate-depth earthquakes (80–130 km) below the Central Andes reveal a fine-scale double-layered Wadati-Benioff zone (WBZ). Upper and lower band of seismicity are separated by about 9 km and occur at the top of the oceanic crust and in the uppermost oceanic mantle, respectively. Analysis of focal mechanisms and waveform similarities indicate that fluid processes are causing the events. Earthquakes in the oceanic crust occur on pre-existing normal faults due to hydraulic embrittlement from metamorphic dehydration, and on subvertical faults that connect the two layers in a narrow depth range. Extensional faulting predominates in both layers, indicating that slab pull forces are the dominant stress source superseding possible unbending forces in this segment of the Nazca plate.

description: Ever science the invention of solar cells, thermodynamics has been used to assess their performance limits, guiding advances in materials science and photovoltaic technology to reduce the gap between the practical efficiencies and the thermodynamic limits to photovoltaic energy conversion. By systematically addressing the thermodynamic efficiency losses in current photovoltaic, ultrahigh efficiency photovoltaic can be expected. Currently, the non-radiative recombination of some ultrahigh efficient solar cells is almost completely suppressed, and the radiative recombination loss is then the key to restrict the further improvement of device performance. This work relates the energy band edge electronic density of states (DOS) of semiconductor absorber and transport layer, excited/transfer state electronic entropy to thermodynamically inevitable energy loss during photoelectric conversion in solar cells. On accounts of the basic limitations of thermodynamic laws on the energy conversion process, this work reveals a hidden variable that affects the photovoltaic performance and puts forward the band edge DOS engineering as a new dimension in performance optimization of solar cell apart from the traditional material and defect passivation engineering, etc. This work highlights the great importance of DOS engineering for further improving the performance of any solar cell devices.

description: We present very high spatial resolution deep radio continuum observations at 5 GHz (6 cm) made with e-MERLIN of the young stars DG Tau A and B. Assuming it is launched very close (~=1 au) from the star, our results suggest that the DG Tau A outflow initially starts as a poorly focused wind and undergoes significant collimation further along the jet (~=50 au). We derive jet parameters for DG Tau A and find an initial jet opening angle of 86 degrees within 2 au of the source, a mass-loss rate of 1.5x10^-8 solar masses/yr for the ionised component of the jet, and the total ejection/accretion ratio to range from 0.06-0.3. These results are in line with predictions from MHD jet-launching theories.

Subjects: citizen science

description: This multi-perspective study investigated the alignment between (1) learning opportunities mentioned by CS project initiators in CS project descriptions available online, (2) learning opportunities shared in tweets from project or platform accounts and, (3) the participants' perceived learning experiences as reflected in survey responses and tweets from individual user accounts. The aim was to identify overlaps and discrepancies between learning opportunities envisioned by project coordinators’ and citizen scientists’ perspectives on learning in CS projects. To this end, we triangulated three datasets - project descriptions (N=94), tweets (N = 216,786) and survey responses (N = 610). The first dataset - a qualitative content analysis of project descriptions stored in the CS Track database – was created in the context of a previous study (cf. section 5.1). The keywords derived from this manual coding of project descriptions were used to conduct an automated analysis of tweets and thus form the basis of the second dataset used in this triangulation study. The third dataset consists of citizen scientists’ responses to the CS Track online survey, which focused primarily on Europe and was distributed for a period of seven months (January-July 2021) through multiple channels. As a second step, we conducted a case study of 11 projects, which allowed us to narrow down the three datasets (project descriptions: N=11, tweets: N=118, survey responses: N=139) and draw conclusions on the level of individual projects. The results of both the general comparison and the project-level case study reveal that there is a significant discrepancy between the learning opportunities described by project coordinators and the learning experiences reported by project participants. This gap is particularly evident with regard to skills related to communication and project or research design, but also when it comes to scientific literacy and critical thinking. What our findings also show is that responses vary considerably even among volunteers who participated in the same CS project, which highlights the important role the citizen scientists’ individual backgrounds, interests and motivations play in shaping their learning experiences.

Probing time orientability of spacetime

description: In general relativity, cosmology and quantum field theory, spacetime is assumed to be an orientable manifold endowed with a Lorentz metric that makes it spatially and temporally orientable. The question as to whether the laws of physics require these orientability assumptions is ultimately of observational or experimental nature, or the answer might come from a fundamental theory of physics. The possibility that spacetime is time non-orientable lacks investigation, and so should not be dismissed straightaway. In this paper, we argue that it is possible to locally access a putative time non-orientability of Minkowski empty spacetime by physical effects involving quantum vacuum electromagnetic fluctuations. We set ourselves to study the influence of time non-orientability on the stochastic motions of a charged particle subject to these electromagnetic fluctuations in Minkowski spacetime equipped with a time non-orientable topology and with its time orientable counterpart. To this end, we introduce and derive analytic expressions for a statistical time orientability indicator. Then we show that it is possible to pinpoint the time non-orientable topology through an inversion pattern displayed by the corresponding orientability indicator, which is absent when the underlying manifold is time orientable.

description: On 12 February 2020, the European Parliament gave its green light for a free trade agreement between the EU and Vietnam. After its conclusion by the Council and ratification by the Vietnamese General Assembly, it is likely to enter into force in early Summer 2020. During the long negotiation period, the project attracted criticism and heightened scrutiny by NGOs and official instances alike, pinpointing, among other issues, the poor track record of Vietnam in terms of human rights and workers' rights. For the latter concern, the European Commission considered that the chapter on sustainable development included in the agreement offered strong and legally binding guarantees. This Insight explores the guarantees for labour protection in Vietnam, provided for by the Trade and Sustainable Development Chapter, and assesses their legal force. This chapter contains substantial guarantees, such as upholding and ratifying standards of the International Labour Organization, as well as procedural guarantees. The latter allow a Party to initiate a conflict resolution procedure if it deems that the other Party does not uphold its commitments to safeguard high labour standards. The Insight concludes that both the substantial and procedural guarantees are rather weak, and that the success of the chapter on sustainable development will ultimately depend on the good will of the Parties.

Nonconvex bundle method with application to a delamination problem

description: Delamination is a typical failure mode of composite materials caused by weak bonding. It arises when a crack initiates and propagates under a destructive loading. Given the physical law characterizing the properties of the interlayer adhesive between the bonded bodies, we consider the problem of computing the propagation of the crack front and the stress field along the contact boundary. This leads to a hemivariational inequality, which after discretization by finite elements we solve by a nonconvex bundle method, where upper-$C^1$ criteria have to be minimized. As this is in contrast with other classes of mechanical problems with non-monotone friction laws and in other applied fields, where criteria are typically lower-$C^1$, we propose a bundle method suited for both types of nonsmoothness. We prove its global convergence in the sense of subsequences and test it on a typical delamination problem of material sciences.
