The Einstein equation should be divided by two
Creators: name: Schmidt, Hans - Juergen
Publisher: name: arXiv
Year: 1996
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We present three reasons for rewriting the Einstein equation. The new version is physically equivalent but geometrically more clear. 1. We write $4 π$ instead of $8 π$ at the r.h.s, and we explain how this factor enters as surface area of the unit 2--sphere. 2. We define the Riemann curvature tensor and its contractions (including the Einstein tensor at the l.h.s.) with one half of its usual value. This compensates not only for the change made at the r.h.s., but it gives the result that the curvature scalar of the unit 2--sphere equals one, i.e., in two dimensions, now the Gaussian curvature and the Ricci scalar coincide. 3. For the commutator $[u,v]$ of the vector fields $u$ and $v$ we prefer to write (because of the analogy with the antisymmetrization of tensors) $$[u,v]\ = \ \frac{1}{2} \, ( \, u\, v \ - \ v \, u \,)$$ which is one half of the usual value. Then, the curvature operator defined by $$ \nabla_{[u} \ \nabla_{v]} \quad - \quad \nabla_{[u,\,v]}$$ (where $\nabla $ denotes the covariant derivative) is consistent with point 2, i.e., it equals one half of the usual value.

Meeting the Constraint of Neutrino-Higgsino Mixing in Gravity Unified Theories

description: In Gravity Unified Theories all operators that are consistent with the local gauge and discrete symmetries are expected to arise in the effective low-energy theory. Given the absence of multiplets like 126 of SO(10) in string models, and assuming that B-L is violated spontaneously to generate light neutrino masses via a seesaw mechanism, it is observed that string theory solutions generically face the problem of producing an excessive $ν_L-{\tilde H}$ mixing mass at the GUT scale, which is some nineteen orders of magnitude larger than the experimental bound of 1 MeV. The suppression of $ν_L-{\tilde H}$ mixing, like proton longevity, thus provides one of the most severe constraints on the validity of any string theory solution. We examine this problem in a class of superstring derived models. We find a family of solutions within this class for which the symmetries of the models and an allowed pattern of VEVs, surprisingly, succeed in adequately suppressing the neutrino-Higgsino mixing terms. At the same time they produce the terms required to generate small neutrino masses via a seesaw mechanism.

description: By path integral Monte Carlo simulations we study the phase diagram of two - dimensional mesoscopic clusters formed by electrons in a semiconductor quantum dot or by indirect magnetoexcitons in double quantum dots. At zero (or sufficiently small) temperature, as quantum fluctuations of particles increase, two types of quantum disordering phenomena take place: first, at small values of quantum de Boer parameter q < 0.01 one can observe a transition from a completely ordered state to that in which different shells of the cluster, being internally ordered, are orientationally disordered relative to each other. At much greater strengths of quantum fluctuations, at q=0.1, the transition to a disordered (superfluid for the boson system) state takes place.

Floquet Spectrum and Two-Terminal Conductance of a Transition Metal Dichalcogenide Ribbon under a Circularly Polarized Laser Field

description: We study the transport properties of a monolayer transition metal dichalcogenide (TMDC) ribbon subject to a time periodic circularly polarized laser field. First, we calculate the quasienergy spectrum within the framework of the Floquet theory and analyze the nontrivial topology of the Floquet bulk gaps. The later is revealed by the presence of chiral edge states inside the bulk gaps in finite samples, in agreement with the calculation of the appropriate winding numbers as a function of both the energy and the amplitude of the laser field. The effect of the time dependent perturbation on the equilibrium edge states is also analyzed. Finally, we calculate the two-terminal conductance and discuss how the above mentioned effects manifest on it. In particular, besides the expected suppression of the bulk conductance and the emergence of edge transport at the Floquet gaps, we find that there is an asymmetry between left and right transmission coefficients (in the zigzag case), leading to pumping effects. In addition, we found that the laser field can lead to a complete switch off of the linear conductance when the later is dominated by the equilibrium edge states.

description: The AR86 strain of Sindbis virus causes lethal neurologic disease in adult mice. Previous studies have identified a virulence determinant at nonstructural protein (nsP) 1 position 538 that regulates neurovirulence, modulates clearance from the CNS, and interferes with the type I interferon pathway. The studies herein demonstrate that in the absence of type I interferon signaling, the attenuated mutant exhibited equivalent virulence to S300 virus. Furthermore, both S300 and nsP1 T538I viruses displayed similar neurovirulence and replication kinetics in IPS-1-/- mice. TRIF dependent signaling played a modest role in protecting against disease by both S300 and nsP1 T538I, but did not contribute to control of nsP1 T538I replication within the CNS, while MyD88 played no role in the disease process. These results indicate that the control of the nsP1 T538I mutant virus is largely mediated by IPS-1-dependent RLR signaling, with TRIF-dependent TLR signaling also contributing to protection from virus-induced neurologic disease.

description: A distributional method to solve the Einstein's field equations for thin shells is formulated. The familiar field equations and jump conditions of Darmois-Israel formalism are derived. A carefull analysis of the Bianchi identities shows that, for cases under consideration, they make sense as distributions and lead to jump conditions of Darmois-Israel formalism.

description: As a result of extreme weather conditions, such as heavy precipitation, natural hillslopes can fail dramatically; these slope failures can occur on a dry day due to time lags between rainfall and pore-water pressure change at depth, or even after days to years of slow-motion. While the pre-failure deformation is sometimes apparent in retrospect, it remains challenging to predict the sudden transition from gradual deformation (creep) to runaway failure. We use a network science method -- multilayer modularity optimization -- to investigate the spatiotemporal patterns of deformation in a region near the 2017 Mud Creek, California landslide. We transform satellite radar data from the study site into a spatially-embedded network in which the nodes are patches of ground and the edges connect the nearest neighbors, with a series of layers representing consecutive transits of the satellite. Each edge is weighted by the product of the local slope (susceptibility to failure) measured from a digital elevation model and ground surface deformation (current rheological state) from interferometric synthetic aperture radar (InSAR). We use multilayer modularity optimization to identify strongly-connected clusters of nodes (communities) and are able to identify both the location of Mud Creek and nearby creeping landslides which have not yet failed. We develop a metric, community persistence, to quantify patterns of ground deformation leading up to failure, and find that this metric increases from a baseline value in the weeks leading up to Mud Creek's failure. These methods promise as a technique for highlighting regions at risk of catastrophic failure.

description: Using micromagnetic simulation, we investigate the self-sustained oscillation of magnetic skyrmion in a ferromagnetic circular nanodot, driven by spin-torque which is generated from a reference layer of a circular nanopillar device. We demonstrate, by lowering the value of uniaxial anisotropy constant ($K_u$), the velocity of the skyrmion can be increased and using this property, gyration frequency of the skyrmion oscillator can be enhanced. Annihilation of the skyrmion at higher current densities, limit the gyration frequency of the oscillator, whereas by modifying the $K_u$ value at the edge of nanodot, we are able to protect the skyrmion from being annihilated at higher current densities which in turn, increases the gyration frequency of the skyrmion based oscillator. By linear fitting the velocity value, obtained from the motion of the skyrmion in a nanostrip, we also predict the gyration frequency of the skyrmion in the nanodot which proves the validity of our idea in an intuitive way. We have also varied the radius of the nanodisk to see its effect on skyrmion.

description: Sylvatic dengue viruses (DENV) are both evolutionarily and ecologically distinct from human DENV and are maintained in an enzootic transmission cycle. Evidence of sylvatic human infections from West Africa and Southeast Asia suggests that sylvatic DENV come into regular contact with humans. Thus, this potential of emergence into the human transmission cycle could limit the potential for eradicating this cycle with vaccines currently in late stages of development. We assessed the likelihood of sylvatic DENV-4 emergence in the face of natural immunity to current human strains and vaccination with two DENV-4 vaccine candidates. Our data indicate homotypic neutralization of sylvatic and human DENV-4 strains by human primary convalescent and vaccinee sera but limited heterotypic immunity. These results suggest that emergence of sylvatic strains into the human cycle would be limited by homotypic immunity mediated by virus neutralizing antibodies produced by natural infection or vaccination.

description: We find a non-perturbative saddle-point solution for the non-linear sigma model proposed by Finkelstein for interacting and disordered electronic systems. Spin rotation symmetry, present in the original saddle point solution, is spontaneously broken at one-loop, as in the Coleman-Weinberg mechanism. The new solution is singular in both the disorder and triplet interaction strengths, and it also explicitly demonstrates that a non-trivial ferromagnetic state appears in a theory where the disorder average is carried out from the outset.

Perturbation of infra-red fixed points and duality in quantum impurity problems

description: We explain in this paper how a meaningful irrelevant perturbation theory around the infra-red (strong coupling) fixed point can be carried out for integrable quantum impurity problems. This is illustrated in details for the spin 1/2 Kondo model, where our approach gives rise to the complete low temperature expansion of the resistivity, beyond the well known $T^2$ Fermi liquid behaviour. We also consider the edge states tunneling problem, and demonstrate by Keldysh techniques that the DC current satisfies an exact duality between the UV and IR regimes. This corresponds physically to a duality between the tunneling of Laughlin quasi particles and electrons, and, more formally, to the existence of an exact instantons expansion. The duality is deeply connected with integrability, and could not have been expected a priori.

description: An introduction to the Propp-Wilson method of coupling-from-the-past for the Ising model is presented. It enables one to obtain exact samples from the equilibrium spin distribution for ferromagnetic interactions. Both uniform and random quenched magnetic fields are included. The time to couple from the past and its standard deviation are shown as functions of system size, temperature, and the field strength. The time should be an estimate of the ergodic time for the Ising system.

We show that reduced quantisation of these models is equivalent to Wheeler-DeWitt quantisation with a particular factor ordering. We then demonstrate how the entropy of black holes can be consistently calculated from these states. While this leads to the Bekenstein-Hawking entropy in the Schwarzschild and non-extreme Reissner-Nordström cases, the entropy for the extreme Reissner-Nordström case turns out to be zero.

 Current status. Valid subspecies: Naboandelus bergevini pygmaeus Linnavuori, 1971 (see LINNAVUORI 1975, 1981; ANDERSEN 1995; POLHEMUS & POLHEMUS 2002).
 Remark. LINNAVUORI (1971) cited the subspecies epithet as pygmaea; pygmaeus (-a, - um) is a Latin adjective meaning ‘of or pertaining to a pygmy or dwarf, especially to the mythical Pygmaei of Africa; short; of reduced statue’. This spelling was accepted in all the subsequent papers (LINNAVUORI 1975 1981; ANDERSEN 1995; POLHEMUS & POLHEMUS 2002). However, as the genus name Naboandelus Distant, 1910 (type species N. signatus Distant, 1910 – see DISTANT 1910) is undoubtedly a masculine, the correct spelling of the subspecies must be Naboandelus bergevini pygmaeus (see ICZN 1999: 31.2, 34.2).

description: While spin qubits based on gate-defined quantum dots have demonstrated very favorable properties for quantum computing, one remaining hurdle is the need to tune each of them into a good operating regime by adjusting the voltages applied to electrostatic gates. The automation of these tuning procedures is a necessary requirement for the operation of a quantum processor based on gate-defined quantum dots, which is yet to be fully addressed. We present an algorithm for the automated fine-tuning of quantum dots, and demonstrate its performance on a semiconductor singlet-triplet qubit in GaAs. The algorithm employs a Kalman filter based on Bayesian statistics to estimate the gradients of the target parameters as function of gate voltages, thus learning the system response. The algorithm's design is focused on the reduction of the number of required measurements. We experimentally demonstrate the ability to change the operation regime of the qubit within 3 to 5 iterations, corresponding to 10 to 15 minutes of lab-time.

description: Like their cellular host counterparts, many invading viral pathogens must contend with, modulate, and utilize the host cell’s chromatin machinery to promote efficient lytic infection or control persistent-latent states. While not intended to be comprehensive, this review represents a compilation of conceptual snapshots of the dynamic interplay of viruses with the chromatin environment. Contributions focus on chromatin dynamics during infection, viral circumvention of cellular chromatin repression, chromatin organization of large DNA viruses, tethering and persistence, viral interactions with cellular chromatin modulation machinery, and control of viral latency-reactivation cycles.

description: Joint gravitational-wave detections of stellar-mass black-hole binaries by ground- and space-based observatories will provide unprecedented opportunities for fundamental physics and astronomy. We present a semianalytic method to estimate multiband event rates by combining selection effects of ground-based interferometers (like LIGO/Virgo) and space missions (like LISA). We forecast the expected number of multiband detections first by using information from current LIGO/Virgo data, and then through population synthesis simulations of binary stars. We estimate that few to tens of LISA detections can be used to predict mergers detectable on the ground. Conversely, hundreds of events could potentially be extracted from the LISA data stream using prior information from ground detections. In general, the merger signal of binaries observable by LISA is strong enough to be unambiguously identified by both current and future ground-based detectors. Therefore third-generation detectors will not increase the number of multiband detections compared to LIGO/Virgo. We use population synthesis simulations of isolated binary stars to explore some of the stellar physics that could be constrained with multiband events, and we show that specific formation pathways might be overrepresented in multiband events compared to ground-only detections.

description: We show that axion domain wall is ferromagnetic in the universe with nonvanishing baryon number or lepton number. It is caused by protons and electrons bounded to the domain wall with their spins aligned. These bound states arise due to attractive potentials generated through pseudo-vector couplings between the fermions and the axion. Using a model of hadronic axions we predict existence of a primordial magnetic field with strength $10^{-13}$ Gauss at recombination.

MATERIAL EXAMINED. — Namibe Province. Praia Amelia, 15°01’S, 12°08’E, 3.VIII.1985, 1 specimen 6 mm preserved length.
DISTRIBUTION. — Thecacera pennigera has been collected from Britain, the Netherlands, France, Sicily, South Africa, Pakistan, Japan, Australia, New Zealand and Brazil (see Willan 1976). Our data represents the first report of this species in Angola.
DESCRIPTION
The background colour is white in the living animal. The whole body is covered by orange, yellow and black spots (Fig. 9). The velum has two lateral prolongations. The rhinophores, the rhinophoral sheath, the gill (with five bipinnate branchial leaves) and the two extrabranchial processes (very long) are covered with orange, yellow and black spots as well.
The radular formula is 8 × (2.2.0.2.2). The innermost lateral tooth is smaller than the second. Both of them have a peaked hook shape (Fig. 7C). The base of the inner lateral is larger than the peak. The two outer lateral teeth are smaller than the inner laterals. The outermost lateral is smaller than the innermost. Both outer laterals are rectangular in shape.
REMARKS
As in our specimen, Thompson & Brown (1984) described specimens of Thecacera pennigera (Montagu, 1815) as being white with numerous irregular-shaped orange areas and black and yellow spots. However, the rhinophores described by Thompson and Brown had a yellow upper part with black speckling, while the whole rhinophore of our specimen is white with black, yellow and orange speckling. The branchial leaves are also similar, but our specimen has not only black and orange, but also yellow spots.

description: As a natural laboratory for the study of crustal growth and accretionary tectonics, the Lhasa terrane was once a microcontinent with a Precambrian basement, which was transformed into a juvenile terrane by remarkable Phanerozoic crustal reworking and growth. Here, we report the geochronological, mineralogical, and geochemical data of the Numa hornblende gabbros and Dongga cumulate hornblende gabbros in the southern Lhasa subterrane (SLS). Zircon U-Pb dating yields ages of 163.7 ± 2.2 Ma and 182.8 ± 2.2 Ma for the Numa hornblende gabbros and Dongga cumulate hornblende gabbros, respectively, which suggests generation in the Early-Middle Jurassic. Both the Numa hornblende gabbros and Dongga cumulate hornblende gabbros are enriched in large ion lithophile elements (LILEs) and depleted in high field strength elements (HFSEs), and they have positive εHf(t) (+11.1 to +17.3) and εNd(t) (+3.6 to +6.0) values. Whole-rock geochemical and isotopic data indicate that their primary magma was derived by the partial melting of a depleted mantle wedge metasomatized by hydrous fluids. Our data, combined with previous research results, indicate that the Numa-Dongga gabbros formed in a continental margin arc setting related to the northward subduction of the Neo-Tethys oceanic slab. In addition, comprehensive studies reveal that the Early Jurassic to Late Cretaceous were the most important periods for crustal growth in the SLS and crustal thickening in the Mesozoic was concentrated mainly in the Early Jurassic (ca. 190–170 Ma) and early Late Cretaceous (ca. 100–80 Ma), which is related to the magmatic flare-up induced by slab roll-back. The recycling of subducted oceanic crust and the underplating of mantle-derived magmas play important roles in the growth and evolution of the continental crust in the SLS.

description: We study the impact of merging supermassive black holes (SMBHs) on the central regions of massive early-type galaxies (ETGs) using a series of merger simulations with varying mass ratios. The ETG models include realistic stellar and dark matter components and are evolved with the GADGET based regularized tree code KETJU. We show that observed key properties of the nuclear stellar populations of massive ETGs, namely flat stellar density distributions (cores), tangentially biased velocity distributions and kinematically decoupled (counter-)rotation can naturally result from a single process $-$ the scouring by SMBHs. Major mergers with mass ratios of $q>1/3$ produce flat, tangentially biased cores with kinematically distinct components. These features originate from spin reversals during the decay of the SMBH orbits caused by gravitational torques from tidally expelled nuclear material. Minor mergers ($q\lesssim1/3$) on the other hand, form non-rotating cores and the tidal reversal becomes less important. Low-density stellar cores scoured in (multiple) minor mergers are less tangentially biased. This implies that the nuclear stellar properties of massive ETGs can be solely explained by stellar dynamical processes during their final assembly without any need for `feedback' from accreting black holes. We predict a strong correlation between decoupled cores, central anisotropy and merger history: decoupled cores form in binary mergers and we predict them to occur in elliptical galaxies with the strongest central anisotropy. Measurements of the central orbital structure are the key to understanding the number of mergers a given galaxy has experienced.

description: The low-frequency rotating plasma instability (spoke) in the ISCT200 thruster operating in the wall-less configuration was simulated with a 3 dimensional PIC MCC code. In the simulations an m = 1 spoke rotating with a velocity of 6.5 km/s in the ExB direction was observed. The rotating electron density structure in the spoke is accompanied by a strongly depleted region of the neutral gas, which clearly shows that the spoke instability is of an ionization nature, similar to the axial breathing mode oscillations. In the simulation the electron cross-field transport through the spoke core was caused by diffusion in the high-frequency (4-10 MHz), short-scale (3 mm) electric field oscillations. These short-scale oscillations play a crucial role in the thruster discharge as over 70% of the electron current to the anode originates from the spoke core. The rest of the current originates from the spoke front where the electron cross-field transport toward the anode is due to the ExB drift in the spoke macroscopic azimuthal electric field.

description: While previous studies have demonstrated that envelope (E) glycoprotein variation between dengue viruses (DENV) genotypes can influence antibody neutralization potency, the mechanisms of variable neutralization remain incompletely understood. Here we characterize epitope antibody interactions of a DENV-3 EDIII binding mouse mAb 8A1 which displays highly variable neutralizing activity against DENV-3 genotypes. Using a DENV-3 reverse genetics platform, we characterize ability of 8A1 to bind and neutralize naturally occurring DENV-3 E genotypic variant viruses. Introduction of single and multiple amino acid mutations into the parental clone background demonstrates that mutations at positions 301 and 383 on EDIII are responsible for 8A1 differential neutralization phenotypes. ELISA and surface plasmon resonance (SPR) studies indicate differences in binding are responsible for the variable neutralization. Variability at position 301 primarily determined binding difference through influencing antibody-EDIII dissociation rate. Our findings are relevant to the many groups focusing on DENV EDIII as a vaccine target.
