description: We investigate time-resolved charge transport through graphene nanoribbons supplemented with adsorbed impurity atoms. Depending on the location of the impurities with respect to the hexagonal carbon lattice, the transport properties of the system may become invisible to the impurity due to the symmetry properties of the binding mechanism. This motivates a chemical sensing device since dopants affecting the underlying sublattice symmetry of the pristine graphene nanoribbon introduce scattering. Using the time-dependent Landauer--B{ü}ttiker formalism, we extend the stationary current-voltage picture to the transient regime, where we observe how the impurity invisibility takes place at sub-picosecond time scales further motivating ultrafast sensor technology. We further characterize time-dependent local charge and current profiles within the nanoribbons, and we identify rearrangements of the current pathways through the nanoribbons due to the impurities. We finally study the behavior of the transients with ac driving which provides another way of identifying the lattice-symmetry breaking caused by the impurities.

description: A definition of surface gravity at the apparent horizon of dynamical spherically symmetric spacetimes is proposed. It is based on a unique foliation by ingoing null hypersurfaces. The function parametrizing the hypersurfaces can be interpreted as the phase of a light wave uniformly emitted by some far-away static observer. The definition gives back the accepted value of surface gravity in the static case by virtue of its nonlocal character. Although the definition is motivated by the behavior of outgoing null rays, it turns out that there is a simple connection between the generalized surface gravity, the acceleration of any radially moving observer, and the observed frequency change of the infalling light signal. In particular, this gives a practical and simple method of how any geodesic observer can determine surface gravity by measuring only the redshift of the infalling light wave. The surface gravity can be expressed as an integral of matter field quantities along an ingoing null line, which shows that it is a continuous function along the apparent horizon. A formula for the area change of the apparent horizon is presented, and the possibility of thermodynamical interpretation is discussed. Finally, concrete expressions of surface gravity are given for a number of four-dimensional and two-dimensional dynamical black hole solutions.

On the Final State of Spherical Gravitational Collapse

description: In a recent paper (FPL 13(6), 543, 2000, astro-ph/9910408), from several independent considerations we showed that GTR does not allow formation of trapped surfaces and finite mass BHs. We rediscuss here several subtle issues involved in this work. So far only the scientific critique to this work was due to Tereno (astro-ph/9905144, astro-ph/9905298) and which was answered in Mitra (astro-ph/9905175, astro-ph/9905175, astro-ph/9905329). Now Tereno (gr-qc/0111073) has also admitted that the local 3-speed of a free particle as conventionally defined by all previous authors and as measured in any coordinate system, is indeed c at the EH. Further since the acceleration SCALAR BLOWS UP at the EH, our result that there cannot be any EH at a finite R is reconfirmed. We explicitly show here that the final state of spherical collapse of very massive stars corresponds to a zero mass BH with 2M/R ->0. But at any finite epoch there would be a Eternally Collapsing Objects (ECO) of finite mass. However, if quantum back reaction in the strong gravity regime would cause a phase transition p ~ rho, there could be static ultracompact objects (UCO) of ~ 10 M (solar). Further, if the phase transition goes proceeds to p= -rho, there could be UCOs of arbitrary high mass (Mazur & Mottola, astro-ph/0109035). Both ECOs and UCOs are expected to possess strong internal magnetic field whereas the the same for a BH is zero. Robertson & Leiter (ApJ 565, 447, 2002, astro-ph/0102381) have shown that the BH candiadates may indeed possess such strong intrinsic mag field. Thus the BHCs are likely to ECOs/UCOs rather than BHs. We also discuss that there is no real evidence for detection of EH.

description: The removal of soil by machine in 1969 for a new reservoir at Arlington uncovered a number of archaeological features. A group on the west side of the river Cuckmere was examined in the limited time available to them by E.W. and H. G. Holden. Of these features a 4th-century pottery kiln, workshop, and a scatter of potsherds have been published (Holden 1979). This report deals with the other features of that site referred to in the 1979 article. That paper should be consulted for a site plan and description of the area.

description: We analyze the thermodynamics and the critical behavior of the supersymmetric su($m$) $t$-$J$ model with long-range interactions. Using the transfer matrix formalism, we obtain a closed-form expression for the free energy per site both for a finite number of sites and in the thermodynamic limit. Our approach, which is different from the usual ones based on the asymptotic Bethe ansatz and generalized exclusion statistics, can in fact be applied to a large class of models whose spectrum is described in terms of supersymmetric Young tableaux and their associated Haldane motifs. In the simplest and most interesting su(2) case, we identify the five ground state phases of the model and derive the complete low-temperature asymptotic series of the free energy per site, the magnetization and charge densities, and their susceptibilities. We verify the model's characteristic spin-charge separation at low temperatures, and show that it holds to all orders in the asymptotic expansion. Using the low-temperature asymptotic expansions of the free energy, we also analyze the critical behavior of the model in each of its ground state phases. While the standard su(1|2) phase is described by two independent CFTs with central charge $c=1$ in correspondence with the spin and charge sectors, we find that the low-energy behavior of the su(2) and su(1|1) phases is that of a single $c=1$ CFT. We show that the model exhibits an even richer behavior on the boundary between zero-temperature phases, where it can be non-critical but gapless, critical in the spin sector but not in the charge one, or critical with central charge $c=3/2$.

description: The elliptic flow of emitted particles and fragments observed in heavy-ion reactions at high energy has become an important observable reflecting the pressure generated in the dense collision zone. More recently, the strength of the nuclear symmetry energy has been investigated by measuring the ratios or differences of the elliptic flows exhibited by neutrons and charged particles in 197Au+197Au collisions at 400 MeV/nucleon incident energy at the GSI laboratory. A moderately soft to linear dependence on density was deduced for a range of densities shown to reach beyond twice the saturation value in these experiments. The known sources of uncertainties and possible model dependencies were thoroughly studied with transport models of the UrQMD and Tuebingen QMD type. A new source of information on the nuclear equation of state at high density has opened up with the observation of the first LIGO and Virgo GW170817 gravitational wave signal from a neutron star merger. The quantitative comparison of terrestrial and celestial results on the basis of measured or inferred neutron star radii or core pressures, including those obtained from X-ray observations, reveals a rather satisfactory agreement. Depending on the precision that can be achieved with future measurements and observations, it will thus become possible to assess the validity of the applied models and methods. The perspectives for improved experiments at FAIR using the NeuLAND and KRAB detection systems are outlined.

description: The first obstacle in building a Geometric Quantization theory for nilpotent orbits of a real semisimple Lie group has been the lack of an invariant polarization. In order to generalize the Fock space construction of the quantum mechanical oscillator, a polarization of the symplectic orbit invariant under the maximal compact subgroup is required. In this paper, we explain how such a polarization on the orbit arises naturally from the work of Kronheimer and Vergne. This occurs in the context of hyperkaehler geometry. The polarization is complex and in fact makes the orbit into a (positive) Kaehler manifold. We study the geometry of this Kaehler structure, the Vergne diffeomorphism, and the Hamiltonian functions giving the symmetry. We indicate how all this fits into a quantization program.

description: One of the mayor topics in astronomy at the beginning of the 19th century was the interpretation of the observations of the first asteroids. In 1810 Christian Ludwig Gerling at the age of twenty two came to Göttingen University to continue his academic studies. Supervised by Carl Friedrich Gauß at the observatory he was engaged in studies of theoretical and practical astronomy. Starting in 1812 Gerling accepted the responsibility for collecting observational data of the asteroid Vesta from the European observatories and for calculating the ephemeris of this new minor planet. In 1817 Gerling was appointed professor at Marburg University. One of his early astronomical projects in Marburg was his contribution to the Berliner Akademische Sternkarten. After completion of his observatory in 1841 Gerling's students started observing and theoretically analysing the orbits of the continuously newly discovered asteroids including the perturbation of the larger solar system bodies. The observations at Gerling's observatory are the first astrometric measurements of solar systems minor bodies of Hesse.

description: Fuelwood is an essential forest product for small-holder farmers in the tropics, but fuelwood harvesting may cause forest degradation and impact ecosystem services. Understanding tree species composition, diversity and biomass changes in forests with active fuelwood collection is important for informing sustainable forest harvesting. In the miombo woodlands of southern Malawi, using forest plots, we investigated: 1) if forests with fuelwood harvesting (n = 50) have different tree, sapling and seedling stem density, species diversity, species composition, and aboveground biomass (AGB) than forests with minimal use (n = 36); and 2) if forest product harvesting pressure and access are predictors of tree stem density, diversity and AGB. We found a significant reduction in tree diversity and AGB but not stem density, and different species composition in areas with fuelwood harvesting compared to reference sites. For saplings, stem density was higher and species composition was different in fuelwood harvesting sites. Seedling Shannon index and Simpson’s diversity were lower in fuelwood harvesting sites. Harvesting pressure and access were predictors of AGB and tree stem density. The reduced AGB and tree species diversity may hinder collection of fuelwood and other forest products, and may reduce ecosystem functioning. Exploring the possibility of forest landscape restoration in the area could be beneficial.

description: Time series forecasting is one of the challenging problems for humankind. Traditional forecasting methods using mean regression models have severe shortcomings in reflecting real-world fluctuations. While new probabilistic methods rush to rescue, they fight with technical difficulties like quantile crossing or selecting a prior distribution. To meld the different strengths of these fields while avoiding their weaknesses as well as to push the boundary of the state-of-the-art, we introduce ForGAN - one step ahead probabilistic forecasting with generative adversarial networks. ForGAN utilizes the power of the conditional generative adversarial network to learn the data generating distribution and compute probabilistic forecasts from it. We argue how to evaluate ForGAN in opposition to regression methods. To investigate probabilistic forecasting of ForGAN, we create a new dataset and demonstrate our method abilities on it. This dataset will be made publicly available for comparison. Furthermore, we test ForGAN on two publicly available datasets, namely Mackey-Glass dataset and Internet traffic dataset (A5M) where the impressive performance of ForGAN demonstrate its high capability in forecasting future values.

description: The quantum gravity is formulated based on gauge principle. The model discussed in this paper has local gravitational gauge symmetry and gravitational field is represented by gauge potential. A preliminary study on gravitational gauge group is presented. Path integral quantization of the theory is discussed in the paper. A strict proof on the renormalizability of the theory is also given. In leading order approximation, the gravitational gauge field theory gives out classical Newton's theory of gravity. It can also give out an Einstein-like field equation with cosmological term. The prediction for cosmological constant given by this model is well consistent with experimental results. For classical tests, it gives out the same theoretical predictions as those of general relativity. Combining cosmological principle with the field equation of gravitational gauge field, we can also set up a cosmological model which is consistent with recent observations.

description: This paper outlines the history, current work performed and future studies planned to investigate selenium concentrations in the Elk River. One of the sources of selenium appears to be related to coal-mining activity; measured selenium concentrations in the stream systems below coal mines are consistently higher than waters above the mines. Various selenium studies have been conducted by government ministries and the coal mines. Further studies are planned to determine what, if any, environmental effects have occurred or can occur. Preliminary results show no effect on native Cutthroat trout embryos in exposed versus reference populations. Results of studies performed in the local waters are discussed here, as well as the proactive approach being taken by industry and government to developing site-specific water quality criteria.

description: Comparatively a little attention has been paid to the factors that obstruct the acceptance of Internet banking in Sri Lanka. This research assimilates constructs such as security and privacy, perceived trust, perceived risk, and website usability. To test the conceptual model, we collected 186 valid responses from customers who use Internet banking in Sri Lanka. The structural equation modelling technique is applied and hypotheses are validated. The findings show perceived trust and website usability are the possible obstructing factors that highly concerned by Internet banking customers. While security and privacy, and perceived risk are not significant and these are not highly concerned by customers in Internet banking acceptance. The age and gender reveal the moderating effect in each exogenous latent constructs relationship. The practical and managerial implications of the findings are also discussed. This country specific study contributes to the advancement of Internet banking acceptance, and offers some useful insights to researchers, practitioners and policy makers on how to enhance Internet banking acceptance for country similar in context.

description: In this paper, we begin a quantization program for nilpotent orbits of a real semisimple Lie group. These orbits and their covers generalize the symplectic vector space. A complex structure polarizing the orbit and invariant under a maximal compact subgroup is provided by the Kronheimer-Vergne Kaehler structure. We outline a geometric program for quantizing the orbit with respect to this polarization. We work out this program in detail for minimal nilpotent orbits in the non-Hermitian case. The Hilbert space of quantization consists of holomorphic half-forms on the orbit. We construct the reproducing kernel. The Lie algebra acts by explicit pseudo-differential operators on half-forms where the energy operator quantizing the Hamiltonian is inverted. The Lie algebra representation exponentiates to give a minimal unitary ladder representation. Jordan algebras play a key role in the geometry and the quantization.

description: The applications of the blockchain technology are still being discov-ered. When a new potential disruptive technology emerges, there is a tendency to try to solve every problem with that technology. However, it is still necessary to determine what approach is the best for each type of application. To find how distributed ledgers solve existing problems, this study looks for blockchain frameworks in the academic world. Identifying the existing frameworks can demonstrate where the interest in the technology exists and where it can be miss-ing. This study encountered several blockchain frameworks in development. However, there are few references to operational needs, testing, and deploy of the technology. With the widespread use of the technology, either integrating with pre-existing solutions, replacing legacy systems, or new implementations, the need for testing, deploying, exploration, and maintenance is expected to in-tensify.

description: This paper describes a community forest project located in the township of Calama, Region II, Northern Chile. The project was initiated in 1996 with a goal to create a 100 hectares of self-sustaining forested ecosystem for a valued oasis in the Atacama Desert. The objectives of the project are: to create a selfsustaining ecosystem with minimal maintenance using native plant species that are drought resistant and to undertake initiatives that will speed up natural successional changes. To meet the above objectives, a local drought-resistant species known as 'algarrobo' (Prosopis chilensis) was selected for the project. The afforestation program includes key elements such as seed preparation; sowing of seeds in greenhouse containers and maintenance; land preparation; transplanting the individual seedlings into the field; and on-going field maintenance and monitoring.

description: We sketch our recent application of a non-commutative version of the Cartan `moving-frame' formalism to the quantum Euclidean space $R^N_q$, the space which is covariant under the action of the quantum group $SO_q(N)$. For each of the two covariant differential calculi over $R^N_q$ based on the $R$-matrix formalism, we summarize our construction of a frame, the dual inner derivations, a metric and two torsion-free almost metric compatible covariant derivatives with a vanishing curvature. To obtain these results we have developed a technique which fully exploits the quantum group covariance of $R^N_q$. We first find a frame in the larger algebra $Ω^*(R^N_q) \cocross \uqs$. Then we define homomorphisms from $R^N_q \cocross U_q^{\pm}{so(N)}$ to $R^N_q$ which we use to project this frame in $Ω^*(R^N_q)$.

description: The Standard Model gauge symmetry is extended by $U(1)_{B-L}$ which when spontaneously broken leads to residual $\mathbb{Z}_4$ symmetry. $U(1)_{B-L}$ gauge symmetry made anomaly free by introducing exotic SM singlets with corresponding $U(1)_{B-L}$ charges of $13$, $-14$, and $15$. $\mathbb{Z}_4$ symmetry ensures the Dirac nature of neutrinos, simultaneously stabilizing dark matter. Dirac neutrino mass is generated through scotogenic scenario. Dark matter, direct detection, cosmological constraints, and collider constraints analysis is performed. $\mathbb{Z}_4$ symmetry predicts the exact absence of neutrinoless double beta decay ($0ν2β$) and gives a prediction for an enhanced neutrinoless quadruple beta decay ($0ν4β$) via which this model can be tested. Model allows for Majorana dark matter as well as for long-lived dark matter candidates.

description: Protein structures are a very special class among all possible structures. It was suggested that a ``designability principle'' plays a crucial role in nature's selection of protein sequences and structures. Here we provide a theoretical base for such a selection principle, using a novel formulation of the protein folding problem based on hydrophobic interactions. A structure is reduced to a string of 0's and 1's which represent the surface and core sites, respectively, as the backbone is traced. Each structure is therefore associated with one point in a high dimensional space. Sequences are represented by strings of their hydrophobicities and thus can be mapped into the same space. A sequence which lies closer to a particular structure in this space than to any other structures will have that structure as its ground state. Atypical structures, namely those far away from other structures in the high dimensional space, have more sequences which fold into them, and are thermodynamically more stable. We argue that the most common folds of proteins are the most atypical in the space of possible structures.

Ring Wormholes in D-Dimensional Einstein and Dilaton Gravity

description: On the basis of exact solutions to the Einstein-Abelian gauge-dilaton equations in $D$-dimensional gravity, the properties of static axial configurations are discussed. Solutions free of curvature singularities are selected; they can be attributed to traversible wormholes with cosmic string-like singularities at their necks. In the presence of an electromagnetic field some of these wormholes are globally regular, the string-like singularity being replaced by a set of twofold branching points. Consequences of wormhole regularity and symmetry conditions are discussed. In particular, it is shown that (i) regular, symmetric wormholes have necessarily positive masses as viewed from both asymptotics and (ii) their characteristic length scale in the big charge limit ($GM^2 \ll Q^2$) is of the order of the ``classical radius" $Q^2/M$.

description: CaLIPSO is an innovative photon detector concept designed for high precision brain PET imaging. For the first time, liquid trimethylbismuth is used as sensitive medium. The detector operates as a time-projection chamber and detects both Cherenkov light and charge signal. Indeed, each 511-keV photon releases a single primary electron that triggers a Cherenkov radiation and ionizes the medium. As trimethylbismuth has never been studied before, we measured its free ion yield defined as the number of electron-ion pairs released by the primary electron. To this end, we developed a low-noise measuring system to determine the weak current induced by a 60Co source in the liquid with an accuracy better than 5 fA for an electric field up to 7kV/cm. We used tetramethylsilane as benchmark liquid to validate the apparatus and we measured a zero-field free ion yield of 0.53 +/- 0.03 in agreement with literature. However, we found a zero-field free ion yield of 0.083 +/- 0.003 for trimethylbismuth, which is a factor 7 lower than the typical values for similar dielectric liquids. Quantum chemistry computations on heavy atoms tend to demonstrate the high ability of trimethylbismuth to capture electrons, which could explain this weak value. This recombination mechanism marks a new step in understanding charge transport in liquid detectors. Finally, to verify the detectability of individual charge pulses, we developed a charge pulse measurement system which has been successfully validated with TMSi. Measurements with TMBi are ongoing.

description: The increased use of DC-consuming electronics in many applications relevant to everyday life, necessitates significant improvements to power conversion and distribution methodologies. The surge in mobile electronics created a new power application space where high efficiency, size, and reduced complexity are critical, and at the same time, many computational tasks are relegated to centralized cloud computing centers, which consume significant amounts of energy. In both those application spaces, conversion and distribution efficiency improvements of even a few-% proves to be more and more challenging. A lot of research and development efforts target each source of loss, in an attempt to improve power electronics such that it serves the advances in other fields of electronics.
      Non-isolated DC-DC converters are essential in every electronics system, and improvements to efficiency, volume, weight and cost are of utmost interest. In particular, increasing the operation frequency and the conversion ratio of such converters serves the purposes of reducing the number or required conversion steps, reducing converter size, and increasing efficiency. The aforementioned improvements can be achieved by using superior technologies for the components of the converter, and by implementing higher level of integration than most present-day converters exhibit.
      In this work, Gallium Nitride (GaN) high electron mobility transistors (HEMT) are utilized as switches in a half-bridge buck converter topology, in conjunction with fine-line 180nm complementary metal oxide semiconductor (CMOS) driver circuitry. The circuits are integrated through a face-to-face bonding technique which results in significant reduction in interconnects parasitics and allows faster, more efficient operation. This work shows that the use of GaN transistors for the converter gives an efficiency headroom that allow pairing converters with state-of-the-art thin-film inductors with magnetic material, a task that is currently usually relegated to air-core inductors.
      In addition, a new "core-clad" structure for thin-film magnetic integrated inductors is presented for the use with fully integrated voltage regulators (IVRs). The core-clad topology combines aspects from the two popular inductor topologies (solenoid and cladded) to achieve higher inductance density and improved high frequency performance.
Cornering top-philic dark matter with colliders and cosmology: the importance of QCD corrections

description: Constraining dark matter models necessitates accurate predictions for large set of observables originating from collider physics, cosmology and astrophysics. We consider two classes of top-philic dark matter models where the dark sector is coupled to the Standard Model via the top quark and study the complementarity of dark matter relic density, direct and indirect detection and collider searches in exploring the model parameter space. We moreover investigate how higher-order corrections affect the results.

description: In 1891, an Anglo-Saxon cemetery was found on the south-west edge of Lewes. Thirty-two or 33 inhumation burials were excavated over a period of several months. They were found in shallow graves about 18 inches deep, cult into the chalk subsoil. Most of the skeletons were oriented east-west, with one or two exceptions. The majority were supine. A large proportion of the grave-goods were weapons, although female ornaments were also found. The material from this site has never been fully described, and is now published for the first time.

description: Typhoon Jebi in 2018 caused severe damage along areas of Osaka Bay, Japan. After the storm, a Japan Society of Civil Engineers (JSCE) coastal survey group surveyed the coastal impacts and recorded watermarks inside Osaka Bay and along the Pacific. The maximum storm tide recorded by a tide gauge was 3.29 m at the Osaka Tide Station, which is a historical high for Osaka Bay. Coastal flooding consisted of both storm surge and wave run-up in almost all locations, with flooding exceeding 5 m and 12 m in elevation from mean sea level in the inner parts of Osaka Bay and along the Pacific coast, respectively. Coastal damage was severe in areas located outside of coastal barriers, such as ports and harbors, while residential areas were mainly well protected and spared due to coastal protection systems. In addition, some inland flooding occurred in the Kobe-Ashiya regions due to the storm surge propagating up several small rivers. This survey report summarizes the findings of the post-event survey by JSCE and analyzes the relation between maximum water level and resulting damage.
