description: We study the Minimal Supersymmetric Standard Model with Minimal Flavour Violation for the case of a large parameter tanbeta and arbitrary values of the supersymmetric mass parameters. We derive several resummation formulae for tanbeta-enhanced loop corrections, which were previously only known in the limit of supersymmetric masses far above the electroweak scale. Studying first the renormalisation-scheme dependence of the resummation formula for the bottom Yukawa coupling, we clarify the use of the sbottom mixing angle in the supersymmetric loop factor Delta_b. As a new feature, we find tan-beta-enhanced loop-induced flavour-changing neutral current (FCNC) couplings of gluinos and neutralinos which in turn give rise to new effects in the renormalisation of the Cabibbo-Kobayashi-Maskawa matrix and in FCNC processes of B mesons. For the chromomagnetic Wilson coefficient C_8, these gluino-squark loops can be of the same size as the known chargino-squark contribution. We discuss the phenomenological consequences for the mixing-induced CP asymmetry in B_d -> phi K_S. We further quote formulae for B_s -> mu^+ mu^- and B_s-B_s-bar mixing valid beyond the decoupling limit and find a new contribution affecting the phase of the B_s-B_s-bar mixing amplitude. Our resummed tan-beta-enhanced effects are cast into Feynman rules permitting an easy implementation in automatic calculations.

Spie al museo

description: Among the spaces inhabited and crossed by spies and spy stories, that of the museum is certainly one of the most intriguing. This essay analyses different spy figures who, for very different reasons and in very different contexts (both real and fictitious), have related with museums: Sir Anthony Blunt, the connoisseurs working in disguise for KGB in Alan Bennett’s play A Question of Attribution (1988), and the Russian secret agents working in an operation’s room hidden in the basement of the Hermitage museum in St. Petersburg in the spy story Op-Center. Mirror Image (1981) by Tom Clancy and Steve Pieczenik, written by Jeff Rovin. There are many reasons for this fortunate marriage between museums and espionage. First of all, the fact that museums prioritize the visual experience make them a very pregnant metaphor for espionage activity, based on observation and control and on tools such as binoculars, magnifying glasses and miniature cameras. Secondly, like the world of espionage, museums are places of danger and ambush, where nothing is what it seems and where it is difficult to make out real from fake. Furthermore, the methods of investigations of the spy are very similar to the art of connoisseurship of the art historian.

description: This is not a story for people who cannot digest acronyms. Indeed, it is as if the secret
services, generally considered, simply could not do without them. If, as many contend,
in the term “military intelligence” resonates the echo of an oxymoron, acronyms may
undoubtedly reach the practical goal of saving mental and phonetic energy, killing not
less than two birds with a single stone. Applied to secret services and intelligence,
acronyms fulfill a double function: they confer an indisputable aura of scientific dignity
to what they aim at referring to, and they conceal behind a succession of usually eerie
capital letters what they also intend to reveal.

Watching (through) the Watchmen: Representation and Deconstruction of the Controlling Gaze in Neil Gaiman’s The Sandman
Creators: name: Croci, Daniele
Publisher: name: Università degli  Studi di Milano
Year: 2014
Subjects: Graphic Novel; Comics studies; Neil Gaiman; Greek tragedy; postmodernism

description: Two of the most widely represented and recognisable cultural examples of the gaze that spies are the supernatural and/or divine eye, which in religious, mythical and tragic narratives seeks and punishes those who misbehave, and on the other hand the controlling, pervasive gaze of technological surveillance, which is typical of modern institutional apparatuses. This essay aims to analyse the ways in which a highly sophisticated, postmodern graphic novel, Neil Gaiman’s The Sandman (1989), elaborates precise representational strategies in order to blend, metaphorize and then deconstruct the aforementioned narratives of control; in the 2000-page fantasy bildungsroman, mythological, pagan and literary elements are combined to shape the Eumenides, a tripartite deity of vengeance which is represented as pure, abstract gaze, and whose inescapable duty is to punish those who act against nature; however, a complex articulation of the concepts of agency and responsibility manages to undermine the ideological foundation of such essentialism, in order to negotiate forms of resistance against vigilance which revolve around the very necessity of the gaze. Michael Foucault’s works about Panopticism, and especially the relationship between power and control provide the theoretical background for such examinations.

description: We extend the Rome-Southampton regularization independent momentum-subtraction renormalization scheme(RI/MOM) for bilinear operators to one with a nonexceptional, symmetric subtraction point. Two-point Green's functions with the insertion of quark bilinear operators are computed with scalar, pseudoscalar, vector, axial-vector and tensor operators at one-loop order in perturbative QCD. We call this new scheme RI/SMOM, where the S stands for "symmetric". Conversion factors are derived, which connect the RI/SMOM scheme and the MSbar scheme and can be used to convert results obtained in lattice calculations into the MSbar scheme. Such a symmetric subtraction point involves nonexceptional momenta implying a lattice calculation with substantially suppressed contamination from infrared effects. Further, we find that the size of the one-loop corrections for these infrared improved kinematics is substantially decreased in the case of the pseudoscalar and scalar operator, suggesting a much better behaved perturbative series. Therefore it should allow us to reduce the error in the determination of the quark mass appreciably.

VoIP Can Still Be Exploited -- Badly

description: VoIP phones are early representatives as well as present enhancers of the IoT. This paper observes that they are still widely used in a traditional, unsecured configuration and demonstrates the Phonejack family of attacks: Phonejack 1 conjectures the exploitation of phone vulnerabilities; Phonejack 2 demonstrates how to mount a denial-of-service attack on a network of phones; Phonejack 3 sniffs calls. It is reassuring, however, that inexpensive devices such as a Raspberry Pi can be configured and programmed as effective countermeasures, thus supporting the approach of integrating both technologies. We demonstrate both attacks and defence measures in a video clip. The concluding evaluations argue that trusting the underlying network security measures may turn out overly optimistic; moreover, VoIP phones really ought to be protected as laptops routinely are today

description: This paper reports the experimental, analytical, and numerical study of resistive-nanoindentation tests performed on gold samples (bulk and thin film). First, the relevant contributions to electrical contact resistance are discussed and analytically described. A brief comparison of tests performed on gold and on natively oxidized metals highlights the high reproducibility and the voltage-independence of experiments on gold(thanks to its oxide-free surface). Then, the evolution of contact resistance during nanoindentation is fully explained in terms of electronic transport regimes: starting from tunneling, electronic transport is then driven by ballistic conduction before ending with pure diffusive conduction. The corresponding analytical expressions, as well as their validity domains, are determined and compared with experimental data,showing excellent agreement. From there, focus is made on the diffusive regime. Resistive-nanoindentation outputs are fully described by analytical and finite-element modeling. The developed numerical framework allows a better understanding of the main parameters: it first assesses the technique capabilities (validity domains, sensitivity to tip defect, sensitivity to rheology, effect of an oxide layer, and so on), butit also validates the different assumptions made on current line distribution. Finally, it is shown that a simple calibration procedure allows a well-resolved monitoring of the contact area during resistive-nanoindentation performed on samples with complex rheologies (ductile thin film on an elastic substrate). Comparison to analytical and numerical approaches highlights the strength of resistive-nanoindentation for continuous area monitoring.

description: Over the past few decades, inflation models have been studied by researchers from different perspectives and conditions in order to introduce a model for the expanding universe. In this paper, we introduce a modified $f(R)$ gravitational model as ($R+γR^{p}$) in order to examine a new condition for inflation models. Given that our studies are related to a modified $f(R)$ gravitational model on the brane, therefore we will encounter modified cosmological parameters. So, we first introduce these modified cosmological parameters such as spectral index, a number of e-folds and etc. Then, we apply these conditions to our modified $f(R)$ gravitational model in order to adapt to the swampland criteria. Finally, we determine the range of each of these parameters by plotting some figures and with respect to observable data such as Planck 2018.

description: In recent years, the proliferation of unmanned aerial vehicles (UAVs) has increased dramatically. UAVs can accomplish complex or dangerous tasks in a reliable and cost-effective way but are still limited by power consumption problems, which pose serious constraints on the flight duration and completion of energy-demanding tasks. The possibility of providing UAVs with advanced decision-making capabilities in an energy-effective way would be extremely beneficial. In this paper, we propose a practical solution to this problem that exploits deep learning on the edge. The developed system integrates an OpenMV microcontroller into a DJI Tello Micro Aerial Vehicle (MAV). The microcontroller hosts a set of machine learning-enabled inference tools that cooperate to control the navigation of the drone and complete a given mission objective. The goal of this approach is to leverage the new opportunistic features of TinyML through OpenMV including offline inference, low latency, energy efficiency, and data security. The approach is successfully validated on a practical application consisting of the onboard detection of people wearing protection masks in a crowded environment.
title: The Relationship of Bulbous Bluegrass and Big Sagebrush in Utah
Creators: name: Cox, Jason D.
Publisher: name: Utah State University
Year: 2013

description: The increase in abundance and distribution of bulbous bluegrass (Poa bulbosa) has been a concern of the Utah Division of Wildlife Resources. Very little research has been conducted to analyze the invasiveness of bulbous bluegrass in the Intermountain West. This study used data from 1982 to 2012 at range trend study sites across the state of Utah to investigate trends in bulbous bluegrass abundance, range expansion, and co-occurrence with big sagebrush (Artemisia tridentata) and cheatgrass (Bromus tectorum). This study addressed the question of whether the increase of bulbous bluegrass correlates with changes in sagebrush and/or cheatgrass in Utah using a log-response ratio analysis. The log-response ratio identified the correlation of dominance of each species to one another over time. Results of this analysis illustrated an increased abundance of bulbous bluegrass in relation to cheatgrass and sagebrush. In addition to the log-response analysis, a series of maps were created that clearly show the increase abundance and range expansion of bulbous bluegrass during the study period. The results illustrate the need for more research to identify if bulbous bluegrass is detrimental to sagebrush populations. The increased abundance of bulbous bluegrass within sagebrush rangelands could threaten desirable flora and fauna and have negative effects on human dimensions and economics. Further research is recommended to identify the effects of bulbous bluegrass on sagebrush rangelands, and whether bulbous bluegrass is detrimental to sagebrush plant communities and how this will affect social and economic aspects of human dimensions. In addition, research is needed to examine whether climatic, landscape, or anthropogenic variables are attributing to the increase of bulbous bluegrass within sagebrush rangelands.

description: In recent years farmers must use integrated crop growing principles. One of the most important principle is to balance usage of mineral elements in crop cultivation, especially nitrogen management. Excessive and unbalanced usage of nitrogen fertilizer reduces nitrogen use efficiency and increases nitrate leaching in surface and groundwater. The dynamics of nitrogen forms in soil at different depths and different plant growth stages are studied to increase the productivity of winter wheat, promoting nitrogen uptake in plants and reducing nitrogen leaching during the vegetation period. Field experiments were carried out at the Research and Training Farm Vecauce of the Latvia University of Life Science and Technologies from 2012 till 2015. Researched factors were nitrogen (N) fertilizer rate: 0 – control, 85, 153, 187, and N rate determined by chlorophylmeter (Yara N-tester) 180 (2012/2013), 150 (2013/2014), 205 (2014/2015) N kg ha-1, nitrogen and sulphur (S) fertilizer rate – N175+S21 kg ha-1, and conditions of the growing seasons: 2012/2013, 2013/2014 and 2014/2015. The content of nitrate (NO3–N) nitrogen and ammonium (NH4–N) nitrogen was determined in the soil layers 0–20 cm, 20–40 cm and 40–60 cm at the growth stages (GS) 30–32, 49–51, 69 and 90–92. All trial years the amount of nitrate nitrogen and ammonium nitrogen in soil decreased during vegetation, but increased with increasing fertilization dose. Nitrate nitrogen content was significantly influenced by year in 0–40 cm soil layer (P < 0.01) and by nitrogen fertilizer in the 20–40 cm soil layer. Ammonium nitrogen content had significant influence only on nitrogen fertilizer at 20–40 cm soil layer (P < 0.05). Average grain yields did not show significant correlation with the nitrate nitrogen and ammonium nitrogen in different soil layers and plant growth stages, except nitrate nitrogen content in soil layer 40–60 cm at GS 30–32 and ammonium nitrogen content in soil layer 40–60 cm at GS 69 and GS 90–92.
Sentimentalism and Karamzin
Creators: name: Tegart, Jarmila Alexandra
Publisher: name: University of British Columbia
Year: 2010

description: The object of this study is to show how the sentimentalist movement in the literatures of Western Europe found its way into Russian literature, and how Karamzin eventually emerged as the most significant representative of the Russian sentimentalist school. The sentimentalist movement, originating in England, soon affected all European literature, particularly the French and the German. Because of Russia's relative isolation, these new tendencies were slow in appearing, but some of the characteristics, namely a sense of the transience of life and vanity of all things, together with an aspiration toward virtue, appeared in the lyrics of Xeraskov, Murav'ev and Sumarokov. These signs of incipient sentimentalism were, however, present only in haphazard form. It was Nikolaj Mixajlovič Karamzin who crystallized these vague tendencies and gave Russian sentimentalism a definite identity. Karamzin's education, his contact with Masonic circles, and his travels in Western Europe drew him toward the mainstream of European culture. His early works are mainly translations of Western European authors, the most significant work being a translation of Julius Caesar, prefaced by an appraisal of Shakespeare's genius. An able and discriminating journalist, Karamzin modelled the Moskovskij Žurnal (Moscow Journal) on the lines of European literary magazines. In this journal he published his most famous works, such as "Bednaja Liza" (Poor Liza), "Natal’ja, bojarskaja doč’" (Natalia, the Boyar's Daughter) and Pis'ma russkogo putesestvennika (Letters of a Russian Traveller). Karamzin popularized the short story and created a wide Russian reading public, commanding the attention of readers with his portrayal of simplicity, virtue and feeling, often set off by a nostalgic pastoralism, but also tinged by suggestions of the romance of the past and of the exotic. His approach to story-telling necessarily involved a considerable degree of the psychological analysis of characters, and this assumes great importance as a prelude to the great Russian novels of the nineteenth century. Considered in the light of the development of Russian literature, Karamzin's most representative work is Letters of a Russian Traveller, which shows his insistence on the sovereignty of the heart and the importance of creating characters as living persons. This work, therefore, remains the first and best example of Russian sentimentalism, which set the norm for a movement that made possible the searching exploration of the human psyche in the great tradition of Russian fiction.
title: The Pliocene/Pleistocene Evolution of the Western Snake River Plain Near Grand View Idaho
Creators: name: DeRaps, Meagan R.
Publisher: name: Utah State University
Year: 2009

description: The Western Snake River Plain provides us with a unique opportunity to study the evolution of basaltic volcanism. In addition to studying the horizontal variation at the surface of the plain, erosion by the Snake River also allows the study of the vertical variation. With the aid of a USGS EDMAP grant we mapped the Dorsey Butte quadrangle and southern half of the Little Joe Butte quadrangle at a scale of 1 :24,000. The quadrangles are located within both the Ada and Elmore counties of southwestern Idaho, approximately 30 km west of Mountain Home and 2 km north of Grand View. The two maps will extend westward the eight 7.5 minute quadrangles previously mapped by Shervais et al. (2002). The result of this work will be an area encompassing 530 square miles centered around Mountain Home that have been geologically mapped at a scale of 1 :24,000. The geology of this area consists predominantly of basaltic volcanism, lake sedimentation, and quaternary faulting. Lava flows, shield volcanoes, and cinder cones dominate the landscape with a concentration of phreatomagmatic deposits along the cliffs of the Snake River.
An eight-meter stratigraphic column was generated from a phreatomagmatic outcrop within the Basaltic Tuff and Breccia of Hayland School. The base of the unit consists of subaerial scoria fall deposits. Above the scoria deposits sedimentary material is present within cross-bedded and massive layers that may be the product of channel flow, subaqueous reworking of material, and/or subaqueous debris flow. The final stages of the Hayland School eruption involved a de-watering of the system resulting in an increase in the proportion of basaltic clasts and finally a basaltic lava flow. The periods of hydration and de-watering of the volcanic system are likely the product of damming of the ancestral Snake River and/or growth of the volcanic edifice above water level.
Geochemical data for the basalts present within and adjacent to the Dorsey Butte and Little Joe Butte quadrangles support the presence of two dominate magma types. The older basalts have compositions consistent with Fe-rich tholeiites while the younger basalts are transitional between olivine tholeiites and alkali olivine basalts. The younger basalts have higher alkali, Mg, and Cr concentrations and higher Mg/Fe ratios. These findings are consistent with previous work by Vetter and Shervais (1992) and White et al. (2002).

description: Abstract Introduction COVID-19 was caused by severe acute respiratory syndrome coronavirus 2 and it spread throughout the world and turned into a severe global pandemic in 2020. The severity of the COVID-19 is wide, ranging from asymptomatic to severe illness that requires mechanical ventilation. Although the curative sector response of Sri Lanka was somewhat different from other countries, it was remarkably effective in preventing community spread. Objective: To assess the average cost of treating Covid 19 patients at Covid Treatment Centre (CTC) in District General Hospital (DGH) Hambantota. Methodology This retrospective costing study was conducted in CTC at DGH, Hambantota in December 2020. The step-down costing method was used in this study. Key informant interviews with the accountant, deputy director, and staff of CTC, reviewing expenditure records of the accountant's office, visiting and taking measurements of the floor area, reviewing relevant literature were used to gather data in this costing study. Results The average cost of treating a Covid 19 patient per day at CTC, DGH Hambantota was Rs 2317.60. The total cost of treating a Covid 19 Patient at DGH Hambantota for 10 days was Rs 23176.00. The cost of treating Covid patients at CTC, DGHH was exceptionally low when compared to other countries. Discussion and conclusion  Treating Covid 19 patients is an economic burden to any health system. Treatment cost was extremely low at DGH, Hambantota and only about 23000 rupees was spent for one patient for 10 days. Drug cost was comparatively low and transport cost was relatively high.

description: A relativistic version of the rational extended thermodynamics of polyatomic gases based on a new hierarchy of moments that takes into account the total energy composed by the rest energy and the energy of the molecular internal mode is proposed. The moment equations associated with the Boltzmann-Chernikov equation are derived, and the system for the first $15$ equations is closed by the procedure of the maximum entropy principle and by using an appropriate BGK model for the collisional term. The entropy principle with a convex entropy density is proved in a neighborhood of equilibrium state, and, as a consequence, the system is symmetric hyperbolic and the Cauchy problem is well-posed. The ultra-relativistic and classical limits are also studied. The theories with $14$ and $6$ moments are deduced as principal subsystems. Particularly interesting is the subsystem with $6$ fields in which the dissipation is only due to the dynamical pressure. This simplified model can be very useful when bulk viscosity is dominant and might be important in cosmological problems. Using the Maxwellian iteration, we obtain the parabolic limit, and the heat conductivity, shear viscosity, and bulk viscosity are deduced and plotted.

Here we explore some geometrical features of the trajectories in state space generated by the decoherence process, connecting the initially robust pure state with the completely decohered mixed state obtained at the end of the evolution. We characterize these trajectories by recourse to the distance between the concomitant time dependent mixed state and different reference states.

description: The Ice Giants Uranus and Neptune have hydrogen-based atmospheres with several constituents that condense in their cold upper atmospheres. A small number of bright cloud systems observed in both planets are good candidates for moist convective storms, but their observed properties (size, temporal scales and cycles of activity) differ from moist convective storms in the Gas Giants. These clouds and storms are possibly due to methane condensation and observations also suggest deeper clouds of hydrogen sulfide (H$_2$S) at depths of a few bars. Even deeper, thermochemical models predict clouds of ammonia hydrosulfide (NH$_4$SH) and water at pressures of tens to hundreds of bars, forming extended deep weather layers. Because of hydrogen's small molecular weight and the high abundance of volatiles, their condensation imposes a strongly stabilizing vertical gradient of molecular weight larger than the equivalent one in Jupiter and Saturn. The resulting inhibition of vertical motions should lead to a moist convective regime that differs significantly from the one occurring on nitrogen-based atmospheres like those of Earth or Titan. As a consequence, the thermal structure of the deep atmospheres of Uranus and Neptune is not well understood. Similar processes might occur at the deep water cloud of Jupiter in Saturn, but the Ice Giants offer the possibility to study these physical aspects in the upper methane cloud layer. A combination of orbital and in situ data will be required to understand convection and its role in atmospheric dynamics in the Ice Giants, and by extension, in hydrogen atmospheres including Jupiter, Saturn and giant exoplanets.

description: Health information systems (HIS) are important for planning policies, programmes and monitoring the impact of them. Finding data sources quickly for effective utilization of collected information are of vital importance in handling any HIS. With the starting of civil registration in 1868 Sri Lankan HIS has been developed and expanded covering many more important areas and had been utilized for health system improvement. Objective of this study was to explore the Sri Lankan HIS and identify the areas need to be improved as reliable information source. This qualitative study was done using a purposive sample of officials from Ministry of Health, Medical Statistics Unit and Registrar General Department as well as reviewing all the relevant accessible reliable literature. Sri Lankan health information system can be categorized in to two subsystems: population based and facility/Institutional based. Population-based HIS includes household surveys regularly conducted by the Department of Censes and Statistic (DCS), and civil registration which is under Department of Registrar General (RGD). Facility-based HIS includes information from curative and preventive sector institutions such as clinical, health and management information systems. Findings revealed although the birth and death coverage are high, quality of cause of death information is still a major problem. Some non-functioning systems as scheduled, under reporting, duplication of data collection was identified as major issues. Many initiatives are suggested to improve the quality of cause of death information, including training regarding medical certification of cause of death based on ICD10 for the relevant officers and use of verbal autopsy procedure. Regulation of information surveillance from one focal point was recommended by the study to prevent duplication and resource wasting and optimal utilization of gathered data.

description: Power curves capture the relationship between wind speed and output power for a specific wind turbine. Accurate regression models of this function prove useful in monitoring, maintenance, design, and planning. In practice, however, the measurements do not always correspond to the ideal curve: power curtailments will appear as (additional) functional components. Such multivalued relationships cannot be modelled by conventional regression, and the associated data are usually removed during pre-processing. The current work suggests an alternative method to infer multivalued relationships in curtailed power data. Using a population-based approach, an overlapping mixture of probabilistic regression models is applied to signals recorded from turbines within an operational wind farm. The model is shown to provide an accurate representation of practical power data across the population.

Hybrid mapping of the Black Hole Shadow in M87

description: We present a reanalysis of the EHT 228 GHz observations of M87. We apply traditional hybrid mapping techniques to the publicly available `network-calibrated' data. We explore the impact on the final image of different starting models, including: a point source, a disk, an annulus, a Gaussian, and an asymmetric double Gaussian. The images converge to an extended source with a size $\sim 44~μ$as. Starting with the annulus and disk models leads to images with the lowest noise, smallest off-source artifacts, and better closure residuals. The source appears as a ring, or edge-brightened disk, with higher surface brightness in the southern half, consistent with previous results. Starting with the other models leads to a surface brightness distribution with a similar size, and an internal depression, but not as clearly ring-like. A consideration of visibility amplitudes vs. UV-distance argues for a roughly circularly symmetric structure of $\sim 50~μ$as scale, with a sharp-edge, based on a prominent minimum in the UV-distribution, and the amplitude of the secondary peak in the UV-plot is more consistent with an annular model than a flat disk model. With further processing, we find a possible modest extension from the ring toward the southwest, in a direction consistent with the southern limb of the jet seen on 3mm VLBI images on a factor of few larger scales. However, this extension appears along the direction of one of the principle sidelobes of the synthesized beam, and hence requires testing with better UV-coverage.

description: Zinc (Zn) salts are often used as nutritional additives in order to promote gut health. The aim of the present study was to assess the effect of two widely used additives in feedstuff, on the intestinal epithelium. In particular, the effect of zinc oxide (ZnO) and zinc chloride (ZnCl2) was investigated in human (INT-407) and porcine (IPI-2I) cell line models. The effect of Zn sources on IPI-21 and INT-407 cell lines was evaluated by a colorimetric viability test using an incubation period of 3 and 24 hours under serum-free conditions. INT407 and IPI-2I showed to be a suitable model of the intestine and a simple tool to investigate the role of Zn supplements. INT407 showed to be the most sensible model to Zn supplements considered, whereas IPI-2I were more resistant. The results of this study contribute to determine the role of zinc in human and swine intestinal epithelium. However, further in vivo experiments may be done to clarify the contribution of Zn supplements in gut health and to improve Zn supplementation in animal feed and in human formulations.

description: We present 0.2" resolution near-infrared integral field spectroscopy of H-alpha emission from six star forming galaxies at z~1.6 (look-back time of ~9.6 Gyr). These observations were obtained with OSIRIS using the Keck Laser Guide Star Adaptive Optics system. All sources have a compact spatial extent of ~1", with an average half light radius of r=2.9 kpc and average dereddened star formation rate of 22 Msolar per year. Based on H-alpha kinematics we find that these six galaxies are dynamically distinguishable, and we classify them as either merger or disk candidate systems. We find three merger systems (HDF-BX1287, HDF-BX1315, and Q1623-BX491) with varying geometries and dynamical properties. Three galaxies (HDF-BMZ1299, Q2343-BX344, and Q2343-BM145) are well-fit by an inclined-disk model with low velocity residuals (20 to 46 km/sec). An average plateau velocity of v_p=185 km/sec is achieved within 1.0 kpc. The majority of observed velocity dispersions (~88 km/sec) can be explained by the residual seeing halo, and are not intrinsic to our sources. However, one merger and one disk candidate have high velocity dispersions (> 200 km/sec) that cannot be solely explained by beam smearing. For two disk candidates, we detect [NII] emission and are able to map the [NII]/H-alpha ratio on kiloparsec scales. In both cases, [NII] emission is more concentrated than H-alpha emission (< 0.2"), and peak ratios are best explained by the presence of an AGN. These are among the weakest known AGN at high redshift, however their emission is strong enough to impact high redshift metallicity studies that use nebular ratios. All disk candidates have likely completed only a few orbital periods, and if left unperturbed are excellent candidates to become present-day spiral galaxies.

Nonpropagation of massive mode on AdS2 in topologically massive gravity

description: Making use of Achucarro-Ortiz (AO) type of dimensional reduction, we study the topologically massive gravity with a negative cosmological constant on AdS2 spacetimes. For a constant dilaton, this two-dimensional model also admits three AdS2 vacuum solutions, which are related to two AdS3 and warped AdS3 backgrounds with an identification upon uplifting three dimensions. We carry out the perturbation analysis around these backgrounds to find what is a physically propagating field. However, it turns out that there is no propagating massive mode on AdS2 background, in contrast to the Kaluza-Klein (KK) type of dimensional reduction. We note that two dimensionally reduced actions are different and thus, the non-equivalence of their on-shell amplitudes is obtained.
