Puzzling Phenomenon of Diffuse Interstellar Bands

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

description: The discovery of the first diffuse interstellar bands (DIBs) dates back to the pioneering years of stellar spectroscopy. Today, we know about 300 absorption structures of this kind. There exists a great variety of the profiles and intensities of DIBs, so they can not be readily described, classified or characterized. To the present day no reliable identification of the DIBs' carriers has been found. Many carriers of DIBs have been proposed over the years. They ranged from dust grains to free molecules of different kinds, and to more exotic specimens, like hydrogen negative ion. Unfortunately, none of them is responsible for observed DIBs. Furthermore, it was shown that a single carrier cannot be responsible for all known DIBs. It is hard to estimate how many carriers can participate in producing these bands. The problem is further complicated by the fact that to this day it is still impossible to find any laboratory spectrum of any substance which would match the astrophysical spectra. Here, a historical outline concerning DIBs is followed by a brief description of their whole population. Then, a special attention is focused on the procedures trying to extract spectroscopic families within the set of all known DIBs.

description: In this work, we present a novel centroiding method based on Fourier space Phase Fitting(FPF) for Point Spread Function(PSF) reconstruction. We generate two sets of simulations to test our method. The first set is generated by GalSim with elliptical Moffat profile and strong anisotropy which shifts the center of the PSF. The second set of simulation is drawn from CFHT i band stellar imaging data. We find non-negligible anisotropy from CFHT stellar images, which leads to $\sim$0.08 scatter in unit of pixels using polynomial fitting method Vakili and Hogg (2016). And we apply FPF method to estimate the centroid in real space, this scatter reduces to $\sim$0.04 in SNR=200 CFHT like sample. In low SNR (50 and 100) CFHT like samples, the background noise dominates the shifting of the centroid, therefore the scatter estimated from different methods are similar. We compare polynomial fitting and FPF using GalSim simulation with optical anisotropy. We find that in all SNR$\sim$50, 100 and 200) samples, FPF performs better than polynomial fitting by a factor of $\sim$3. In general, we suggest that in real observations there are anisotropy which shift the centroid, and FPF method is a better way to accurately locate it.

description: Georgia is known for its widespread geological formations, particularly mud volcanoes. These formations are mainly found in the Iori plateau and the Gombori Range in the Kakheti region, with smaller occurrences in the Trialeti range near Kavtiskhevi. The Kila-Kupra fold in the Iori plateau hosts three mud volcanoes: Kila-Kupra East, Central, and West. To investigate the genesis of these volcanoes, water and oil samples were collected for geochemical analysis, currently being processed at the University of Utah. Additionally, 2D seismic data provided by Frontera Eastern Georgia and analyzed using IHS Kingdom software revealed that the Kila-Kupra mud volcanoes are associated with a fault-complicated dome in an asymmetric anticline structure. The study suggests that Middle Sarmatian sediments are the source of these volcanoes, based on paleontological and petrographic analysis of breccia samples, which included foraminifera indicating older sediments than previously thought.

description: The Born approximation, based on $\barα\equivα(m_Z)$ instead of $α$, reproduces all electroweak precision measurements within their $(1σ)$ accuracy. The low upper limits for the genuinely electroweak corrections constitute one of the major achievements of LEP. The astonishing smallness of these corrections results from the cancellation of a large positive contribution from the heavy top quark and large negative contributions from all other virtual particles. It is precisely the non-observation of electroweak radiative corrections that places stringent upper and lower limits on the top mass.

subject: FOS: Economics and business

description: Economists emphasize the costs in dollars or other desirable outcomes of additional safety in contrast to safety experts who remind people to design safe products and operate them safely. Society loses emotionally and financially from traumatic injury. The emotional loss must be balanced against allowing individuals free choice and encouraging them to develop judgment. Individuals are viewed as making their own best safety decisions, although they must have good information and face the correct indentives. Currently, society subsidizes risk taking in many ways, thereby discouraging safety. Health and life insurance ought to be required along with liability insurance, to correct the incentives to drivers. In addition, regulation is required to deal with physical externalities.

description: Generalized Baumslag-Solitar groups (GBS groups) are groups that act on trees with infinite cyclic edge and vertex stabilizers. Such an action is described by a labeled graph (essentially, the quotient graph of groups). This paper addresses the problem of determining whether two given labeled graphs define isomorphic groups; this is the isomorphism problem for GBS groups. There are two main results and some applications. First, we find necessary and sufficient conditions for a GBS group to be represented by only finitely many reduced labeled graphs. These conditions can be checked effectively from any labeled graph. Then we show that the isomorphism problem is solvable for GBS groups whose labeled graphs have first Betti number at most one.

description: New York State began enforcing a mandatory automobile safety belt use law on January 1, 1985. We present a preliminary analysis of its effect on fatalities and injuries. Applying a Poisson statistical model to pre- and post-law belt usage rates together with counts of fatalities and injuries in 12 metropolitan areas, we estimate the first six months' application of the law averted 220 fatal, 1,500 severe, 4,600 moderate, and 2,600 light injuries across the state. The Poisson approach gives estimates of injuries averted considerably greater than simple year to year comparisons, indicating that media announcements have understated the efficacy of requiring safety belt usage.
A third Strang lemma and an Aubin-Nitsche trick for schemes in fully discrete formulation

description: In this work, we present an abstract error analysis framework for the approximation of linear partial differential equation (PDE) problems in weak formulation. We consider approximation methods in fully discrete formulation, where the discrete and continuous spaces are possibly not embedded in a common space. A proper notion of consistency is designed, and, under a classical inf-sup condition, it is shown to bound the approximation error. This error estimate result is in the spirit of Strang's first and second lemmas, but applicable in situations not covered by these lemmas (because of a fully discrete approximation space). An improved estimate is also established in a weaker norm, using the Aubin--Nitsche trick. We then apply these abstract estimates to an anisotropic heterogeneous diffusion model and two classical families of schemes for this model: Virtual Element and Finite Volume methods. For each of these methods, we show that the abstract results yield new error estimates with a precise and mild dependency on the local anisotropy ratio. A key intermediate step to derive such estimates for Virtual Element Methods is proving optimal approximation properties of the oblique elliptic projector in weighted Sobolev seminorms. This is a result whose interest goes beyond the specific model and methods considered here. We also obtain, to our knowledge, the first clear notion of consistency for Finite Volume methods, which leads to a generic error estimate involving the fluxes and valid for a wide range of Finite Volume schemes. An important application is the first error estimate for Multi-Point Flux Approximation L and G methods. In the appendix, not included in the published version of this work, we show that classical estimates for discontinuous Galerkin methods can be obtained with simplified arguments using the abstract framework.

description: It is stressed that a measurement of the electric dipole amplitude for direct photon emission in $\kpm$ decays through its interference with inner bremsstrahlung is important for differentiating among various models. Effects of amplitude CP violation in the radiative decays of the charged kaon are analyzed in the Standard Model in conjunction with the large $N_c$ approach. We point out that gluon and electromagnetic penguin contributions to the CP-violating asymmetry between the Dalitz plots of $\kpm$ are of equal weight. The magnitude of CP asymmetry ranges from $2\times 10^{-6}$ to $1\times 10^{-5}$ when the photon energy in the kaon rest frame varies from 50 MeV to 170 MeV.

description: Recently, a $4$-index generalization of the Einstein theory is proposed by Moulin (Eur. Phys. J. C 77, 878 (2017)). Using this method, we find the most general $2$-index field equations derivable from the Einstein-Hilbert action. The application of Newtonian limit, the role of gravitational coupling constant and the effects of the properties of ordinary energy-momentum tensor in obtaining a $4$-index gravity theory have been studied. We also address the results of building Weyl free $4$-index gravity theory. Our study displays that both the Einstein and Rastall theories can be obtained as the subclasses of a $4$-index gravity theory which shows the power of $4$-index method in unifying various gravitational theories. It is also obtained that the violation of the energy-momentum conservation law may be allowed in $4$-index gravity theory, and moreover, the contraction of $4$-index theory generally admits a non-minimal coupling between geometry and matter field in the Rastall way. This study also shows that, unlike the Einstein case, the gravitational coupling constant of $4$-index Rastall theory generally differs from that of the ordinary $2$-index Rastall theory.

Year: 1993
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We consider a minimal technicolor model in which the ordinary and technicolor sectors are coupled by a {\it massless} scalar doublet. When technicolor interactions become strong, the resulting technicolor condensate not only breaks the electroweak symmetry, but also causes the scalar to develop a vacuum expectation value. With the appropriate choice of the scalar's Yukawa couplings, fermion masses are generated, giving us the conventional pattern of flavor symmetry breaking. Although no explicit scalar mass term appears in the full lagrangian of the model, the pseudoscalar states that remain in the low-energy effective theory gain sufficient mass through technicolor interactions to evade detection. We show that this model does not generate unacceptably large flavor changing neutral currents, and is consistent with the experimental constraints on oblique electroweak radiative corrections. We determine the experimentally allowed region of the model's parameter space, and discuss the significance of a phenomenologically viable model that has no arbitrary dimensionful parameters. In terms of parameter counting, our model is the simplest possible extension of the standard model.

description: A class of circular 64-QAM that combines 'geometric' and 'probabilistic' shaping aspects is presented. It is compared to square 64-QAM in back-to-back, single-channel, and WDM transmission experiments. First, for the linear AWGN channel model, it permits to operate close to the Shannon limits for a wide range of signal-to-noise ratios. Second, WDM simulations over several hundreds of kilometers show that the obtained signal-to-noise ratios are equivalent to - or slightly exceed - those of probabilistic shaped 64-QAM. Third, for real-life validation purpose, an experimental comparison with unshaped 64-QAM is performed where 28% distance gains are recorded when using 19 channels at 54.2 GBd. This again is in line - or slightly exceeds - the gains generally obtained with probabilistic shaping. Depending upon implementation requirements (core forward-error correcting scheme for example), the investigated modulation schemes may be key alternatives for next-generation optical systems.

description: The continuous spectra of the substars with surrounding protoplanetary disks were calculated. The results reveal that protoplanetary disc average temperature decreases to 3 K during the period of 5 Myr for substars with masses 0.01M_{Sun} and during the period of 160 Myr for substars with masses 0.08M_{Sun}. Estimations of protoplanetary discs flux maximum depending on the substar mass at the age of 1 Myr are: 4.6 kJy (for 0.01M_{Sun}) and 3.4 MJy (for 0.08M_{Sun}). Maximum of protoplanetary disc radiation before it reaches the temperature of the cosmic microwave background changes within the ranges: from 0.07 mm to 0.58 mm (for substar mass 0.01M_{Sun}) and from 0.02 mm to 0.29 mm (for substar mass 0.08M_{Sun}).

description: We present a novel algorithm for computing collision-free navigation for heterogeneous road-agents such as cars, tricycles, bicycles, and pedestrians in dense traffic. Our approach currently assumes the positions, shapes, and velocities of all vehicles and pedestrians are known and computes smooth trajectories for each agent by taking into account the dynamic constraints. We describe an efficient optimization-based algorithm for each road-agent based on reciprocal velocity obstacles that takes into account kinematic and dynamic constraints. Our algorithm uses tight fitting shape representations based on medial axis to compute collision-free trajectories in dense traffic situations. We evaluate the performance of our algorithm in real-world dense traffic scenarios and highlight the benefits over prior reciprocal collision avoidance schemes.

description: Trading in a secondary stock market not only redistributes wealth among investors but also generates information that guides subsequent real decisions. We provide a disclosure model that reflects both functions of the secondary market. By partially preempting traders' information advantage established from information acquisition, disclosure reduces incentives for private information acquisition. The resulting reduction in information acquisition has two opposite effects on firm value. On one hand, it narrows the information gap between informed and uninformed traders and improves the liquidity of firm shares. On the other hand, it reduces the informational feedback from the stock market to real decisions. The optimal disclosure policy is determined by the trade-off between liquidity enhancement and the investment efficiency. The model explains why the firm value could be higher in an environment that promotes disclosure and private information production at the same time and why growth firms are endogenously more opaque than value firms.

description: Background: Evidence suggests that fluctuations of cortisol and vital signs can emerge during the course of mild Traumatic Brain Injury (mTBI). Objective: To investigate fluctuations of cortisol and vital signs during the acute phase of mTBI in hospitalised patients. Methods: 30 participants (19 patients with mTBI and 11 controls) were examined for saliva cortisol dynamics, heart rate (HR), systolic arterial pressure (SAP), diastolic arterial pressure (DAP), mean arterial pressure (MAP) and body temperature (BT) fluctuations for four consecutive days. Also, the participants completed the Athens Insomnia Scale and Epworth Sleepiness Scales, in order to check for sleep problems. Results: Patients showed elevated levels of cortisol relative to controls (peak at 8 am and lowest levels at 12 am), as well as for most physiological parameters. MAP was significantly higher for patients throughout the measurement period, and BT was elevated for patients relative to controls at almost all measurements of the first and second day. Mean HR tended to track at non-significantly higher levels for the mTBI group. Patients' sleepiness and insomnia values (ESS and AIS) were initially significantly higher relative to controls but the difference dissipated by day 4. Conclusion: The increase in absolute values of cortisol and vital signs measurements, indicates that in the acute phase of mTBI, a stressfulprocess is activated which may affect sleep quality as well.

description: We present and discuss the results of calculations of surface relaxations and rumplings for the (001) and (011) surfaces of BaTiO3 and PbTiO3, using a hybrid B3PW description of exchange and correlation. On the (001) surfaces, we consider both AO (A = Ba or Pb) and TiO2 terminations. In the former case, the surface AO layer is found to relax inward for both materials, while outward relaxations of all atoms in the second layer are found at both kinds of (001) terminations and for both materials. The surface relaxation energies of BaO and TiO2 terminations on BaTiO3 (001) are found to be comparable, as are those of PbO and TiO2 on PbTiO3 (001), although in both cases the relaxation energy is slightly larger for the TiO2 termination. As for the (011) surfaces, we consider three types of surfaces, terminating on a TiO layer, a Ba or Pb layer, or an O layer. Here, the relaxation energies are much larger for the TiO-terminated than for the Ba or Pb-terminated surfaces. The relaxed surface energy for the O-terminated surface is about the same as the corresponding average of the TiO and Pb-terminated surfaces on PbTiO3, but much less than the average of the TiO and Ba-terminated surfaces on BaTiO3. We predict a considerable increase of the Ti-O chemical bond covalency near the BaTiO3 and PbTiO3 (011) surface as compared to both the bulk and the (001) surface.

description: Gallium arsenide (GaAs) is the widest used second generation semiconductor with a direct band gap and increasingly used as nanofilms. However, the magnetic properties of GaAs nanofilms have never been studied. Here we find by comprehensive density functional theory calculations that GaAs nanofilms cleaved along the <111> and <100> directions become intrinsically metallic films with strong surface magnetism and magnetoelectric (ME) effect. The surface magnetism and electrical conductivity are realized via a combined effect of transferring charge induced by spontaneous electric-polarization through the film thickness and spin-polarized surface states. The surface magnetism of <111> nanofilms can be significantly and linearly tuned by vertically applied electric field, endowing the nanofilms unexpectedly high ME coefficients, which are tens of times higher than those of ferromagnetic metals and transition metal oxides.

description: We report the beginning of the astronomical masers investigations in the 3-mm bandwidth at the radio telescope RT-22 (CrAO, Ukraine). For this purpose the special complex for maser lines investigation in 85...115 GHz frequency band is developed. It is made on the base of the low noise cryogenic Shottky-diode receiver and the high resolution Fourier-spectrometer. The cryogenic receiver has the DSB noise temperature less than 100K. The spectral channel separation of the Fourier-spectrometer is about 4kHz and the spectrometer bandwidth is 8 MHz. Results of maser observations of 8$^{0}-7^{1} $A$^{+}$ transition of methanol (95.169 GHz) towards DR-21(OH), DR-21W and NGC7538 are in good agreement with early obtained results by other authors. On the basis of the analysis of the location of masers in the NGC7538 direction we can assume that the origin of all known class I methanol masers in this region is connected with existing molecular outflows from young stars.

Towards reconstructing the quantum effective action of gravity

description: Starting from a parameterisation of the quantum effective action for gravity we calculate correlation functions for observable quantities. The resulting templates allow to reverse-engineer the couplings describing the effective dynamics from the correlation functions. Applying this new formalism to the autocorrelation function of spatial volume fluctuations measured within the Causal Dynamical Triangulations program suggests that the corresponding quantum effective action consists of the Einstein-Hilbert action supplemented by a non-local interaction term. We expect that our matching-template formalism can be adapted to a wide range of quantum gravity programs allowing to bridge the gap between the fundamental formulation and observable low-energy physics.

description: For decades, macroeconomists have listened to criticism from their professional colleagues about the absence of micro-foundations from most of what they say and do. A typical comment is: "I don't understand much about macroeconomics; how is it related to economics?" A possibly less-frivolous comment is that nothing can be said about macroeconomic policy until economists develop a macroeconomic theory from a microeconomic foundation. Anything less is branded "ad hoc" and dismissed.

Non-universal soft scalar masses in supersymmetric theories

Year: 1993
Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: The existence of non--universal soft masses is the most general situation in supersymmetric theories. We study the consecuences that this situation has for the low--energy sparticle spectrum. In particular, we analize in detail the contribution to the scalar mass renormalization group equations of the $U(1)_Y$ D--term. We obtain analytic expressions for the evolution of masses of the three generations and these allow us to show that such a contribution can produce important modifications on the spectrum. The necessity to avoid flavour changing neutral currents does not constrain this result. Finally, we discuss a realistic example in the context of string theory where the departure from universality is large.

Unconventional multi-band superconductivity in bulk SrTiO$_{3}$ and LaAlO$_{3}$/SrTiO$_{3}$ interfaces

description: Although discovered many decades ago, superconductivity in doped SrTiO$_{3}$ remains a topic of intense research. Recent experiments revealed that, upon increasing the carrier concentration, multiple bands cross the Fermi level, signaling the onset of Lifshitz transitions. Interestingly, $T_{c}$ was observed to be suppressed across the Lifshitz transition of oxygen-deficient SrTiO$_{3}$; a similar behavior was also observed in gated LaAlO$_{3}$/SrTiO$_{3}$ interfaces. Such a behavior is difficult to explain in the clean theory of two-band superconductivity, as the additional electronic states provided by the second band should enhance $T_{c}$. Here, we show that this unexpected behavior can be explained by the strong pair-breaking effect promoted by disorder, which takes place if the inter-band pairing interaction is subleading and repulsive. A consequence of this scenario is that, upon moving away from the Lifshitz transition, the two-band superconducting state changes from opposite-sign gaps to same-sign gaps.

Information Spillovers and Performance Persistence in Private Equity Partnerships

description: We present a simple model that rationalizes performance persistence in private equity partnerships. In contrast to the model for mutual funds of Berk and Green (2004), the learning in our model pertains to profitability associated with an emerging sector or an innovative trading strategy, rather than ability specfiic to the fund manager. As a result of potential information spillovers, which would increase competition in the sector if informed investors were to partner with nonincumbent managers, incumbent managers will let informed investors benefit from increases in estimated profitability following high realized returns in the sector.
Hidden-strange molecular states and the $Nϕ$ bound state via a QCD van der Waals force

description: In this work, we study the hidden-strange molecular states composed of a baryon and a vector meson in a coupled-channel $Nρ-Nω-Nϕ-ΛK^*-ΣK^*$ interaction. With the help of the effective Lagrangians which coupling constants are determined by the SU(3) symmetry, the interaction is constructed and inserted into the quasipotential Bethe-Salpeter equation to search for poles in the complex plane, which correspond to molecular states. Two poles are found with a spin parity $3/2^-$ near the $Nρ$ and the $ΣK^*$ thresholds, which can be related to the $N(1700)$ and the $N(2100)$, respectively. No pole near the $Nϕ$ threshold can be found if direct interaction between a nucleon and $ϕ$ meson is neglected according to the OZI rule. After introducing the QCD van der Waals force between a nucleon and $ϕ$ meson, a narrow state can be produced near the $Nϕ$ threshold. Inclusion of the QCD van der Waals force changes the line shape of the invariant mass spectrum in the $Nϕ$ channel leading to a worse agreement with the present low-precision data. Future experiments at BelleII, JLab, and other facilities will be very helpful to clarify the existence of these possible hidden-strange molecular states.

description: Several different controlled vocabularies have been developed and used by the astronomical community, each designed to serve a specific need and a specific group. The Unified Astronomy Thesaurus (UAT) attempts to provide a highly structured controlled vocabulary that will be relevant and useful across the entire discipline, regardless of content or platform. As two major use cases for the UAT include classifying articles and data, we examine the UAT in comparison with the Astronomical Subject Keywords used by major publications and the JWST Science Keywords used by STScI's Astronomer's Proposal Tool.

Information Economics and Accounting Measurement: A Blueprint for Scholarly Research

description: In this essay, we wish to make a single, simple argument. That is, if information problems are the primary root of the accounting problems, then modern information economics should be the center of accounting research. In making this argument, we plan to first revisit a somewhat elementary accounting question. Using the question as a spring-board, we retrace the rise of information economics in the accounting discipline. Finally, we argue that to answer similarly posed questions, accounting theory needs a (modern) information-economics core. It also needs to build accounting measurement structure based on the core. Such an accounting theory, hopefully, connects with the existing framework of accounting practice at a fundamental level and ought to guide accounting research, education, and policy-making.
Inflationary Changes

description: Most economists looking ahead to 1970 expect the rate of inflation to slow as the effects of government's anti-inflation policies begin to show up in the prices of the goods and services each of us buys and sells. Inflation is defined as a sustained rise in some broad based index of prices, so the effects of the policies designed to slow the current inflation will not become apparent until the indexes show a slower rate of increase. In the less inflationary environment for 1970 that I and others envision, many prices will continue to rise but, on the average, the rise will be smaller than in 1969.
