description: Electron correlations in molecules can be divided in short range dynamical correlations, long range Van der Waals type interactions and near degeneracy static correlations. In this work we analyze for a one-dimensional model of a two-electron system how these three types of correlations can be incorporated in a simple wave function of restricted functional form consisting of an orbital product multiplied by a single correlation function $f(r_{12})$ depending on the interelectronic distance $r_{12}$. Since the three types of correlations mentioned lead to different signatures in terms of the natural orbital (NO) amplitudes in two-electron systems we make an analysis of the wave function in terms of the NO amplitudes for a model system of a diatomic molecule. In our numerical implementation we fully optimize the orbitals and the correlation function on a spatial grid without restrictions on their functional form. Due to this particular form of the wave function, we can prove that none of the amplitudes vanishes and moreover that it displays a distinct sign pattern and a series of avoided crossings as a function of the bond distance in agreement with the exact solution. This shows that the wave function Ansatz correctly incorporates the long range Van der Waals interactions. We further show that the approximate wave function gives an excellent binding curve and is able to describe static correlations. We show that in order to do this the correlation function $f(r_{12})$ needs to diverge for large $r_{12}$ at large internuclear distances while for shorter bond distances it increases as a function of $r_{12}$ to a maximum value after which it decays exponentially. We further give a physical interpretation of this behavior.

A New Guest in the Third Quantized Multiverse

description: In the present article we point out a conceptual issue of the Third Quantization formalism for Canonical Quantum Gravity. Based on earlier results on interuniversal entanglement, the picture of noninteracting universe-antiuniverse pairs is incomplete. In particular, the variation of the entanglement entropy with the scale factor, understood as a measure of time, implies either an interaction between pairs of universes or universes with a heat bath, i.e. an external field. We propose a simple solution to the problem by adding a new quantum field to the formalism. Correspondingly, particles of this field mediate interactions between universes -- depending on the model at tree level or one loop -- and may further provide a heat bath in the background.

Non-equilibrium Transport in the Strange Metal and Pseudogap phases of the Cuprates

description: We propose that the non-equilibrium current measured in the $a-b$ plane of an underdoped cuprate (in either the strange metal or pseudogap regime) in contact with either an overdoped cuprate or a standard Fermi liquid can be used diagnose how different the pseudogap and strange metals are from a Fermi liquid. Naively one expects the strange metal to be more different from a Fermi liquid than is the pseudogap. We compute the expected non-equilibrium transport signal with the three Green functions that are available in the literature: 1) marginal Fermi liquid theory, 2) the phenomenological ansatz for the pseudogap regime and 3) the Wilsonian reduction of the Hubbard model which contains both the strange metal and pseudogap. All three give linear IV curves at low bias voltages. Significant deviations from linearity at higher voltages obtain only in the marginal Fermi liquid approach. The key finding, however, is that IV curves for the strange metal/Fermi liquid contact that exceed that of the pseudogap/Fermi liquid system. If this is borne out experimentally, this implies that the strange metal is less orthogonal to a Fermi liquid than is the pseudogap. Within the Wilsonian reduction of the Hubbard model, this result is explained in terms of a composite-particle picture. Namely, the pseudogap corresponds to a confinement transition of the charge degrees of freedom present in the strange metal. In the strange metal the composite excitations break up and electron quasiparticles scatter off bosons. The bosons here, however, do not arise from phonons but from the charge degrees of freedom responsible for dynamical spectral weight transfer.

description: Food affordability is of critical concern to any nation, being a key component of food security. Price volatility phenomenon is linked with food affordability because escalating food prices reduces low-income earners’ food access. With the COVID-19 pandemic, planting activities by farmers in Nigeria have been negatively impacted in the 2019/20 planting season. Hunger may therefore be looming in the coming periods because food production output will be lowered. Understanding volatility in the prices of food therefore becomes very important if any meaningful solutions are to be proffered. In this study, we sought to measure volatility in prices of important staple foods using the GARCH approach and then investigate the factors that drive them over the period 1970-2019. Our result revealed persistent volatility in food prices over the period under review. It was revealed that insurgency, political stability in neighbouring countries, trade liberalization, GDP per capita, inflation rate, government effectiveness, crop production, crude oil price and exchange rate were prominent drivers of volatility in food commodity prices. The study therefore recommends the pursuance of a peaceful nation that is capable of supporting sustainable and increased agricultural production. We as well recommend mechanisms that better regulates inter-border food trading activities whereas strategies of price stabilization policies and government interventions in the pre-liberalization era should be re-visited. It becomes necessary to embrace a holistic approach to economic planning given the tendencies for macroeconomic variables to drive volatility in food prices

Dynamical Models of Elliptical Galaxies -- I. Simple Methods

description: We study dynamical models for elliptical galaxies, deriving the projected kinematic profiles in a form that is valid for general surface-brightness profiles and (spherical) total mass profiles, without the need for any explicit deprojection. We then show that an almost flat rotation curve, combined with modest velocity anisotropy, is already sufficient to recover the kinematic profiles of nearby ellipticals. As an application, we provide two different sets of mass estimators for elliptical galaxies, based on either the velocity dispersion at a specific location near the effective radius, or the aperture-averaged velocity dispersion. In the large aperture (virial) limit, mass estimators are naturally independent of anisotropy. The spherical mass enclosed within the effective radius $R_{\rm e}$ can be estimated as $2.4 R_{\rm e} \langle σ^{2}_{\rm p} \rangle/ G$, where $\langle σ^2_{\rm p} \rangle$ is the average of the squared velocity dispersion over a finite aperture. This formula does not depend on assumptions such as mass-follows-light, and is a compromise between the cases of small and large apertures sizes. Its general agreement with results from other methods in the literature makes it a reliable means to infer masses in the absence of detailed kinematic information. If on the other hand the velocity dispersion profile is available, tight mass estimates can be found that are independent of the mass-model and anisotropy profile (within $\approx$ 10% accuracy). Explicit formulae are given for small anisotropy, large radii and/or power-law total densities. Motivated by recent observational claims, we also discuss the issue of weak homology of elliptical galaxies, emphasizing the interplay between morphology and orbital structure.

description: Pets and animal-assisted intervention sessions have shown to be beneficial for humans' mental, social, and physical health. However, for specific populations, factors such as hygiene restrictions, allergies, and care and resource limitations reduce interaction opportunities. In parallel, understanding the capabilities of animals' technological representations, such as robotic and digital forms, have received considerable attention and has fueled the utilization of many of these technological representations. Additionally, recent advances in augmented reality technology have allowed for the realization of virtual animals with flexible appearances and behaviors to exist in the real world. In this demo, we present a companion virtual dog in augmented reality that aims to facilitate a range of interactions with populations, such as children and older adults.We discuss the potential benefits and limitations of such a companion and propose future use cases and research directions.

In this demonstration, users play a recycling game in which they are awarded for proper recycling procedures. The application provides users with visual and auditory feedback as well as various interaction cues. Prior research shows that VR experiences can influence behavior in the physical world and can be particularly powerful in behavior modification. This application aims to transfer real recycling behaviors to participants and can be used to study the effects of VR on behavior modification.

description: We calculate the nonequilibrium conductance of a system of two capacitively coupled quantum dots, each one connected to its own pair of conducting leads. The system has been used recently to perform pseudospin spectroscopy by controlling independently the voltages of the four leads. The pseudospin is defined by the orbital occupation of one or the other dot. Starting from the SU(4) symmetric point of spin and pseudospin degeneracy in the Kondo regime, for an odd number of electrons in the system, we show how the conductance through each dot varies as the symmetry is reduced to SU(2) by a pseudo-Zeeman splitting, and as bias voltages are applied to any of the dots. We analize the expected behavior of the system in general, and predict characteristic fingerprint features of the SU(4) to SU(2) crossover that have not been observed so far.

description: We report the observation of the spin Peltier effect (SPE) in the ferrimagnetic insulator Yttrium Iron Garnet (YIG), i.e. a heat current generated by a spin current flowing through a Platinum (Pt)|YIG interface. The effect can be explained by the spin torque that transforms the spin current in the Pt into a magnon current in the YIG. Via magnon-phonon interactions the magnetic fluctuations modulate the phonon temperature that is detected by a thermopile close to the interface. By finite-element modelling we verify the reciprocity between the spin Peltier and spin Seebeck effect. The observed strong coupling between thermal magnons and phonons in YIG is attractive for nanoscale cooling techniques.

description: In virtual environments, we are able to have an augmented embodiment with various virtual avatars. Also, in physical environments, we can extend the embodiment experience using Supernumerary Robotic Limbs (SRLs) by attaching them to the body of a person. It is also important to consider for the feedback to the operator who controls the avatar (virtual) and SRLs (physical). In this work, we use a servo motor and Galvanic Vestibular Stimulation to provide feedback from a virtual interaction that simulates remotely controlling SRLs. Our technique transforms information about the virtual objects into haptic and proprioceptive feedback that provides different sensations to an operator.

Altitudinal distribution: 0-550 m a. s. l.
Host plant: In Greece, adults of the species have been collected on various shrubs and trees, especially those of the genera Arbutus and Quercus (Drosopoulos and Asche 2000). As of now, the only recorded plant of the nymph and the freshly emerged adults is Asphodelus microcarpus Parl (Asphodelaceae) (Drosopoulos 2003). In Bulgaria, during the early summer, it was collected on a new host plant of Asphodeline lutea (L.) Rchb. (Asphodelaceae). Later in the season, when the plant's ground mass had wilted, it moved as adults on to woody species of the genus Quercus.
Additional notes: In Greece, it usually lives in the same habitat as Philaenus spumarius, more often near the sea, but there are also isolated records from the mountains (Drosopoulos and Asche 2000). In Bulgaria, it has been collected along the southern Black Sea coast and there are also isolated records in the mountains, near the border with Greece. Colour polymorphism is observed. Rare in Bulgaria.

description: The electrostatic tactile display could render the tactile feeling of different haptic texture surfaces by generating the frictional force through voltage modulation when a finger is sliding on the display surface. However, it is challenging to prepare and fine-tune the appropriate frictional signals for haptic design and texture simulation. We present FrictGAN, a deep-learningbased framework to synthesize frictional signals for electrostatic tactile displays from fabric texture images. Leveraging GANs (Generative Adversarial Networks), FrictGAN could generate the displacement-series data of frictional coefficients for the electrostatic tactile display to simulate the tactile feedback of fabric material. Our preliminary experimental results showed that FrictGAN could achieve considerable performance on frictional signal generation based on the input images of fabric textures.

Nanoconfinement Facilitates Reactions of Carbon Dioxide in Supercritical Water

description: The reactions of CO$_2$ in water under extreme pressure-temperature conditions are of great importance to the carbon storage and transport below Earth's surface, which substantially affect the carbon budget in the atmosphere. We applied ab initio molecular dynamics simulations to study aqueous carbon solutions nanoconfined by graphene and stishovite (SiO$_2$) at 10 GPa and 1000$\sim$1400 K. We found that CO$_2$(aq) reacts more in nanoconfinement than in bulk. The stishovite-water interface makes the solutions more acidic, which shifts the chemical equilibria, and the interface chemistry also affects the reaction mechanisms. Our findings suggest that CO$_2$(aq) in deep Earth may be more active than previously thought, and confining CO$_2$ and water in nanopores may enhance the efficiency of mineral carbonation.

description: In this work we present a search for molecular line emission in the interacting luminous infrared galaxy Arp 157 (NGC 520). We report the detection of 19 different lines, from 12 different molecular species in our 3mm line survey and supporting 2mm and 1mm observations. We investigated the profiles of the detected lines, and find all species show asymmetric emission lines, with profiles that differ systematically as a function of critical density. We derive the physical conditions within the gas reservoir of this system using isotope ratios, an excitation analysis, and rotation diagrams. We suggest that in this source we are observing a warm (Tex > 23K) edge-on, asymmetric starburst ring, plus a less dense central molecular component, which is more optically thin. We compare our molecular abundances with several well studied galaxies, and with Galactic regions, in order to determine the primary driver of the chemistry in Arp 157. We highlight some significant differences between the abundances of molecules in this source and in the more extreme ultra-luminous infrared galaxy Arp 220. This suggests that different physical mechanisms may become important in driving gas chemistry at different points in the evolution of a merger induced starburst. Of the nearby galaxies we considered, NGC 253 (whose nuclear chemistry is dominated by large-scale shocks) and NGC 1068 (whose nuclear chemistry is X-ray dominated) have the most similar molecular abundances to Arp 157. The Galactic region Sgr B2(OH) (where shock desorption of ices is thought to be important) may also have similar abundances to Arp 157. We hence postulate that shocks and/or the generation of hard radiation fields by the ongoing merger (or a starburst wind), are driving the molecular chemistry in Arp 157.

description: The current approach to train Cardiopulmonary Resuscitation (CPR) is to employ a mannequin device replicating the physical properties of a real human head and torso. This aims to ensure a correct transfer of the cardiac massage location, amplitude and frequency in a real situation. However, this type of training does not replicate the stress that may be elicited in the presence of a real victim ; this may result in reduced CPR performances or even errors. Virtual Reality (VR) may alleviate this lack by adding visual immersion with a Head-Mounted Display (HMD) so that the trainee is cut from the potential distractions of the real surrounding and can fully engage in a more faithful training scenario. However, one must ensure in the first place that using this technology maintains the quality of the CPR. Hence, we have conducted an experimental study to evaluate the potential of visual immersion in such a training context (limited to the cardiac massage). One important requirement was to ensure a correct hand tracking while executing the standard CPR two-hands pose. In the present paper we describe first how we assessed a simple approach using two HTC-Vive trackers. Results show that the proposed minimal setup based on a single hand tracking is validated for frequency and, with correction, for amplitude. Then, to assess the quality of the training, we performed an evaluation study considering the following two factors: Haptic feedback with the mannequin device (with/out) and Real-time Performance feedback (with/out) in the HMD. We observed that the visually immersive experience proposed in this paper delivers a sufficient level of spatial presence, involvement and agency. Integrating the real CPR mannequin in VR has a significantly positive impact on the massage performance quality whereas displaying the real-time performance in the virtual environment tends to be only useful for the frequency when no mannequin is used.

description: Networks play a prominent role in the study of complex systems of interacting entities in biology, sociology, and economics. Despite this diversity, we demonstrate here that a statistical model decomposing networks into matching and centrality components provides a comprehensive and unifying quantification of their architecture. First we show, for a diverse set of networks, that this decomposition provides an extremely tight fit to observed networks. Consequently, the model allows very accurate prediction of missing links in partially known networks. Second, when node characteristics are known, we show how the matching-centrality decomposition can be related to this external information. Consequently, it offers a simple and versatile tool to explore how node characteristics explain network architecture. Finally, we demonstrate the efficiency and flexibility of the model to forecast the links that a novel node would create if it were to join an existing network.

description: In the field of augmented reality (AR), many applications involve user interfaces (UIs) that overlay visual information over the user's view of their physical environment, e.g., as text, images, or three-dimensional scene elements. In this scope, optical seethrough head-mounted displays (OST-HMDs) are particularly interesting as they typically use an additive light model, which denotes that the perception of the displayed virtual imagery is a composite of the lighting conditions of one's environment, the coloration of the objects that make up the virtual imagery, and the coloration of physical objects that lay behind them. While a large body of literature focused on investigating the visual perception of UI elements in immersive and flat panel displays, comparatively less effort has been spent on OST-HMDs. Due to the unique visual effects with OST-HMDs, we believe that it is important to review the field to understand the perceptual challenges, research trends, and future directions. In this paper, we present a systematic survey of literature based on the IEEE and ACM digital libraries, which explores users' perception of displaying text-based information on an OST-HMD, and aim to provide relevant design suggestions based on the meta-analysis results. We carefully review 14 key papers relevant to the visual perception research in OST-HMDs with UI elements, and present the current state of the research field, associated trends, noticeable research gaps in the literature, and recommendations for potential future research in this domain.

Doubts about the crucial role of the rising-tube mechanism in the formation of sunspot groups

description: Some preliminary processing results are presented for a dataset obtained with the Solar Optical Telescope on the Hinode satellite. The idea of the project is to record, nearly simultaneously, the full velocity and magnetic-field vectors in growing active regions and sunspot groups at a photospheric level. Our ultimate aim is to elaborate observational criteria to distinguish between the manifestations of two mechanisms of sunspot-group formation --- the rising of an Omega-shaped flux tube of a strong magnetic field and the in situ amplification and structuring of magnetic field by convection (the convective mechanism is briefly described). Observations of a young bipolar subregion developing within AR 11313 were carried out on 9--10 October 2011. Based on the series of filtergrams, the trajectories of corks are computed, using a technique similar to but more reliable than local correlation tracking (LCT), and compared with the magnetic maps. At this stage of the investigation, only the vertical magnetic field and the horizontal flows are used for a qualitative analysis. According to our preliminary findings, the velocity pattern in the growing active region has nothing to do with a spreading flow on the scale of the entire bipolar region, which could be expected if a tube of strong magnetic field emerged. No violent spreading flows on the scale of the entire growing magnetic region can be identified. Instead, normal mesogranular and supergranular flows are preserved. The observed scenario of evolution seems to agree with Bumba's inference that the development of an active region does not entail the destruction of the existing convective-velocity field. The convective mechanism appears to be better compatible with observations than the rising-tube mechanism.

description: Amblyopia is a neurological impairment where children suffer from the insufficient visual gathering. Recent studies investigated the ability to improve amblyopic children's visual acuity. However, according to previous theories, visual acuity is the foundation for an excellent visual system, but more lies beyond acuity improvements, such as their visual cognition and perceptual skills. Virtual Reality acts as a serious game medium for active learning of virtual depth perceptions built after a solid improvement for visual acuity. This paper aims to provide a pediatric-centered practical approach for amblyopic children. We designed a game system in the form of a virtual depth hierarchical game pyramid based upon the classical visual perception hierarchical pyramid and standardized procedures for perceptual training. The bottom-up setup gradually trains for each level up the VR-designed hierarchy while building up a solid foundation.

description: The use of 1-bit analog-to-digital converters (ADCs) is seen as a promising approach to significantly reduce the power consumption and hardware cost of multiple-input multiple-output (MIMO) receivers. However, the nonlinear distortion due to 1-bit quantization fundamentally changes the optimal communication strategy and also imposes a capacity penalty to the system. In this paper, the capacity of a Gaussian MIMO channel in which the antenna outputs are processed by an analog linear combiner and then quantized by a set of zero threshold ADCs is studied. A new capacity upper bound for the zero threshold case is established that is tighter than the bounds available in the literature. In addition, we propose an achievability scheme which configures the analog combiner to create parallel Gaussian channels with phase quantization at the output. Under this class of analog combiners, an algorithm is presented that identifies the analog combiner and input distribution that maximize the achievable rate. Numerical results are provided showing that the rate of the achievability scheme is tight in the low signal-to-noise ratio (SNR) regime. Finally, a new 1-bit MIMO receiver architecture which employs analog temporal and spatial processing is proposed. The proposed receiver attains the capacity in the high SNR regime.
