description: A biological regulatory network can be modeled as a discrete function that contains all available information on network component interactions. From this function we can derive a graph representation of the network structure as well as of the dynamics of the system. In this paper we introduce a method to identify modules of the network that allow us to construct the behavior of the given function from the dynamics of the modules. Here, it proves useful to distinguish between dynamical and structural modules, and to define network modules combining aspects of both. As a key concept we establish the notion of symbolic steady state, which basically represents a set of states where the behavior of the given function is in some sense predictable, and which gives rise to suitable network modules. We apply the method to a regulatory network involved in T helper cell differentiation.

description: We present an analysis of the near-infrared spectrum of a young massive star cluster in the overlap region of the interacting galaxies NGC 4038/39 using population synthesis models. Our goal is to model the cluster population as well as provide rough constraints on its initial mass function (IMF). The cluster shows signs of youth such as thermal radio emission and strong hydrogen emission lines in the near-infrared. Late-type absorption lines are also present which are indicative of late-type stars in the cluster. The strength and ratio of these absorption lines cannot be reproduced through either late-type pre-main sequence (PMS) stars or red supergiants alone. Thus we interpret the spectrum as a superposition of two star clusters of different ages, which is feasible since the 1" spectrum encompasses a physical region of ~90 pc and radii of super-star clusters are generally measured to be a few parsecs. One cluster is young (<= 3 Myr) and is responsible for part of the late-type absorption features, which are due to PMS stars in the cluster, and the hydrogen emission lines. The second cluster is older (6 Myr - 18 Myr) and is needed to reproduce the overall depth of the late-type absorption features in the spectrum. Both are required to accurately reproduce the near-infrared spectrum of the object. Thus we have directly detected PMS objects in an unresolved super-star cluster for the first time using a combination of population synthesis models and pre-main sequence tracks. This analysis serves as a testbed of our technique to constrain the low-mass IMF in young super-star clusters as well as an exploration of the star formation history of young UC HII regions.

description: We report the discovery of two sources at z=3.867 and z=3.427 that exhibit powerful starburst and AGN activities. They benefit from data from radio to X rays from the CFHTLS-D1/SWIRE/XMDS surveys. Follow-up optical and near-infrared spectroscopy, and millimeter IRAM/MAMBO observations are also available. We performed an analysis of their spectral energy distributions to understand the origin of their emission and constrain their luminosities. A comparison with other composite systems at similar redshifts from the literature is also presented. The AGN and starburst bolometric luminosities are ~10^13 Lsun. The AGN emission dominates at X ray, optical, mid-infrared wavelengths, and probably in the radio. The starburst emission dominates in the far-infrared. The estimated star formation rates range from 500 to 3000Msun/yr. The AGN near-infrared and X ray emissions are heavily obscured in both sources with an estimated dust extinction Av>4, and Compton-thick gas column densities. The two sources are the most obscured and most luminous AGNs detected at millimeter wavelengths currently known. The sources presented in this work are heavily obscured QSOs, but their properties are not fully explained by the standard AGN unification model. In one source, the ultraviolet and optical spectra suggest the presence of outflowing gas and shocks, and both sources show emission from hot dust, most likely in the vicinity of the nucleus. Evidence of moderate AGN-driven radio activity is found in both sources. The two sources lie on the local M_BH-M_bulge relation. To remain on this relation, their star formation rate has to decrease. Our results support evolutionary models that invoke radio feedback as star formation quenching mechanism, and suggest that such a mechanism might play a major role also in powerful AGNs.

description: The Guichon Creek Batholith, located in south-central British Columbia, contains several large, low grade copper deposits of extreme economic importance. A three dimensional model for the batholith has been determined on the basis of a gravity survey conducted in 1971. In addition the gravity data has been compared with the filtered aeromagnetic maps of the batholith. A striking correlation between the spatial relationship of the mineral deposits and the core of the batholith has been discovered.

description: The SEI conducts independent technical assessments (ITAs) periodically for any programs that request them, looking at both technical and programmatic aspects. Such requests often come from either programs that are experiencing challenges with delivering their systems or from external stakeholders to check on the progress that is being made. In the course of performing such an assessment, the ITA team may interview as many as 50 to 100 people from the program mangement office (PMO) staff, contractor staff, users, and other external stakeholder organizations, all under assurance of anonymity. Interviewees generally give very open and candid responses, giving the team insight into what is actually happening on a program and the ability to gain a deep understanding of the pressures and incentives under which people are operating. One notable aspect of such assessments is that similar problems arise across separate and dissimilar programs. The key questions that arise when conducting assessments of many different programs are “Why do some of these adverse behaviors keep happening across entirely different programs?” and “Is there a way to stop them?” In this blog post, I discuss the recurring problem in software acquisition and development of what I call clinging to the old ways. I describe the behavior in the context of a real-world scenario and provide recommendations on recovering from and preventing future occurrences of this problem. Future posts in this series will explore other recurring problems.
Related investigations of pi 2 micropulsations
Creators: name: Smith, Brian Paul
Publisher: name: University of British Columbia
Year: 2011

description: Related investigations of irregular, nighttime, type Pi 2 micropulsations were undertaken with regards to the source and occurrence of these geomagnetic fluctuations. In particular, the local times of Pi 2's recorded by a global network of stations, during 1964, were determined. From this, the Pi 2 daily occurrence maximum was observed near 2230 LMT. For this same year (1964), rapid-run magnetograms from Memambetsu, Japan and Wingst, Germany were analyzed. The initial orientation of the impulsive Pi 2 disturbance vectors was observed to be primarily northeast (north-west) before (after) 2230 LMT. These results suggest that Pi 2 source field lines lie near the 2230 LMT meridian. Further investigations of the globally observed Pi 2's were made regarding variations in morphology with magnetic activity. The daily occurrence maximum of Pi 2 was found earlier (later) at 2030 (2330) LMT during intervals of high (low) magnetic activity. In this manner, the longitudinal shift of the Pi 2 source is revealed. A statistical study of solar wind protons observed by Explorer 34 satellite was made during the intervals of high, and of low, magnetic activity. This study showed that the Pi 2 source shift may be due to a change in the solar wind flow direction and/or processes associated with changes in the solar wind proton pressure. Pi 2’s are a train of pulsations having quasi-periods ranging from 40 to 150 seconds and each series lasts about 10 minutes. The periods of Pi 2 micropulsations recorded at Ralston, Canada during 1967 were correlated with simultaneous, Alouette 2 satellite received, VLF radio signals. Some of these VLF emission phenomena, known as 'whistler cutoff’ and 'lower hybrid resonance noise band breakup', indicated the location of the magnetospheric plasmapause. Other emissions, known as ELF, were believed to indicate the plasma sheet inner boundary. The variation of the period of the Pi 2's with the indicated magnetospheric subregion locations showed that Pi 2 period varies systematically with positions of the plasma sheet inner boundary during intervals of magnetic quiescence. The results imply a latitudinal (radial) movement of the Pi 2 source in a region near the plasma sheet inner boundary. Lastly, the rate of Pi 2 occurrence with magnetic activity, during 1964 and 1967, was found to be maximum when the planetary index of magnetic activity, Kp, was 1+ to 2-. The mean Kp index most closely approaches this optimum level during the years of sunspot minimum. Thus, the rate of occurrence result is consistent with the inverse relationship of Pi 2 yearly occurrence with the solar cycle. In summation, the source studies revealed a ‘dynamic’ Pi 2 source, in the sense that it varies both latitudinally and longitudinally. An association was shown between Pi 2 and nightside magnetospheric processes and subregions. The occurrence study indicated that processes generating Pi 2’s are not clear but approach optimum when the Kp level is between 1+ and 2-.

The contributions of the quark loops (Hartree-Fock approximation) and the meson loops (next 1/N_c-approximation where N_c is the number of colors) are taken into account. These contributions, as we show, are the values of the same order of magnitude. For the f_0 decay the K-loop contribution turns out to play the dominant role. The results are in satisfactory agreement with modern experimental data.

Does depressive symptomology moderate the relationship between alexithymic traits and emotion perception ability?
Creators: name: Dell, BH
Publisher: name: University Of Tasmania
Year: 2023

description: While a relationship between alexithymic traits and emotion perception difficulties has been consistently demonstrated, no prior research has examined whether depressive symptomology influences this relationship. The present study examined the relationship between alexithymic traits and the ability to identify a range of dynamically displayed basic emotions (happiness, sadness, and fear), across various emotion intensity levels (20%, 60%, and 100%), and whether depressive symptomology moderated this relationship. One-hundred and twenty participants (68 females; aged 18 to 65 years, `M` = 24.95, `SD` = 7.19) completed the Toronto Alexithymia Scale, the Depression, Anxiety, and Stress Scale, and the Emotion Recognition Task. The present results indicate that higher levels of alexithymic traits may be associated with a reduced ability to identify fear at full intensity levels, which provides some limited support for the prior literature. Furthermore, higher levels of depressive symptomology may be associated with an enhanced ability to identify fear at low intensity levels, which provides tentative support for the negative bias in emotion processing typically found in depressed individuals. However, no further enhancement, attenuation, or moderation effects were evident. Future research in individuals with higher levels of alexithymic traits and depressive symptomology is required to support these findings and to better inform potential targeted treatment programs for those who may be experiencing interpersonal difficulties.

description: The black hole X-ray transient, XTE J1118+480, has now twice been observed in outburst - 2000 and 2005 - and on both occasions remained in the low/hard X-ray spectral state. Here we present radio, infrared, optical, soft X-ray and hard X-ray observations of the more recent outburst. We find that the lightcurves have very different morphologies compared with the 2000 event and the optical decay is delayed relative to the X-ray/radio. We attribute this lesser degree of correlation to contributions of emission from multiple components, in particular the jet and accretion disc. Whereas the jet seemed to dominate the broadband spectrum in 2000, in 2005 the accretion disc seems to be more prominent and we use an analysis of the lightcurves and spectra to distinguish between the jet and disc emission. There also appears to be an optically thin component to the radio emission in the 2005 data, possibly associated with multiple ejection events and decaying as the outburst proceeds. These results add to the discussion that the term "low/hard state'" covers a wider range of properties than previously thought, if it is to account for XTE J1118+480 during these two outbursts.

Exploring the motivations underlying the use of paralinguistic digital affordances on Facebook
Creators: name: Fish, LR
Publisher: name: University Of Tasmania
Year: 2023

description: Paralinguistic digital affordances (PDAs) are the most commonly used feature on SNS. However, relativity little is known about the factors that influence their use. The current study aimed to further investigate the use of PDAs on Facebook, by considering how social capital and the positivity bias influence the use of PDAs. and examine the effect of narcissism subtypes on motivations to use PDAs. It was hypothesised that more PDA responses would be given to both positive images and strong ties. It was also hypothesised that grandiose narcissism would positivity predict motivations to use PDAs as assertive self-presentation tactics; that vulnerable narcissism would positivity predict motivations to use PDAs as both assertive and defensive self-presentation tactics and that vulnerable narcissism would predict positivity predict the motivation to consider consequences and other user's emotion prior to using PDAs. Facebook users (`N` = 136) responded to fictitious Facebook posts (in a 3 x 2 design, with positive, neutral and negative images purportedly posted by strong and weak social ties) and measures of narcissism and PDA motivations. Results were that the positivity bias is not only present in the content posted on Facebook, but also in PDA response. Individuals were just a likely to respond to close and weak ties for positive images but were less likely to respond to negative valanced images when posted by a weak tie. Analysis via multiple regression indicated that both grandiose and vulnerable narcissism predicted the motivations to use PDAs as assertive and defensive self-presentation tactics. The findings offer theoretical contributions to the fluctuation hypothesis and spectrum model of narcissism, providing a potential avenue for future research. It can be concluded that the simple act of creating a PDA on Facebook has surreptitiously complex motivational bias.

A thermal instability mechanism for glacier surges
Creators: name: Hoffman, Joseph Walter
Publisher: name: University of British Columbia
Year: 2011

description: A theory of thermal conduction instabilities that could account for many of the properties of surging glaciers is presented. A one-dimensional diffusion equation with advection is solved numerically using a variation of the Crank-Nicholson method. Geothermal and frictional heating are shown to dominate the melting of ice from the base of the glacier, and the water that is formed is assumed to flow in an approximately uniform sheet between glacier and bedrock. The sliding theory developed by Weertman is used to determine the effects of parameters such as geothermal heat flow, basal shear stress, and bedrock roughness on the behavior of surging glaciers. A cyclic evolution of the temperature profile near the bed of a surging glacier is discovered and is thought to be a principal factor in starting the surge and in determining the surge period. Some good correlation with observation is obtained when the theory is applied to models which resemble known surging glaciers. An attempt to predict the future surge behavior of the Rusty Glacier, Yukon (previously known as the "Fox" Glacier) from the temperature data of Classen and Clarke produced uncertain results.
The influence of personality on the making of snap decisions and change of mind
Creators: name: Frazer, BJ
Publisher: name: University Of Tasmania
Year: 2023

description: The present study is interested in whether personality such as impulsivity, stubbornness and the need for closure affect the way in which an individual makes a snap decision and subsequently rates their confidence in their decision or changes their mind. Fifty-two participants from the University of Tasmania completed 3 personality inventories and a memory task. Participants were shown a study list of words to memorise. Half of these words appeared in the experimental phase as old‚ÄövÑvp words, and the other half were new‚ÄövÑvp. In a two-step decision process, participants were first to make a snap decision if the word was old or new. They were then to rate their confidence in their answer or change their mind if they made an error. Analysis showed that there were limited differences in the way that participants responded to the first decision. For the second response, the need for closure and dysfunctional impulsivity (a subset of impulsivity) were found to have the strongest correlation with the number of response reversals and the use of the high confidence option. However, a key limitation to the study was the small sample size, which prevents the null from being supported or rejected. Additionally, the inventory used to measure stubbornness was inadequate for differentiating between participants. In future replications of this study, a larger sample size should be used, and new measure of stubbornness should be developed.
The morphology and sediment transport dynamics of the Seven Mile Beach spit
Creators: name: Watt, EJ
Publisher: name: University Of Tasmania
Year: 2023

description: Sandy coasts and dune systems are dynamic and changing environments. A study on the morphology and sediment transport dynamics of the Seven Mile Beach spit in south eastern Tasmania supports this notion. The Seven Mile Beach spit is a mid-bay spit that projects into the waters of Frederick Henry Bay and Pitt Water, the mouth of the drowned Coal River Valley. The spit contains significant coastal dune features, including bare mobile dune ridges and over-steepened dunes covered with marram grass. A combination of aerial photography and GIS analysis, demonstrated that significant changes in shoreline position and land cover type have occurred to the spit during the past fifty years. During this period, it was found that the toe of the spit was migrating east, while episodic retreat on the southern side and deposition on the northern side occurred. Analysis of land cover change indicated that marram grass has been particularly successful in colonising the area. Marram grass cover increased during the fifty year period from 15% to over 50% of the study area, displacing areas of native vegetation and bare sand. Field monitoring techniques provided primary data on sediment transport dynamics at the study site. Results indicate that there were significant differences between sand transport at bare and marram grass covered sites, and in the amount of sand transported at different elevations above the surface. The proximity of the sample sites to the active dune system also influenced the amount of sand deposition. Erosion pin data and the monitoring of a highly mobile dune slip face illustrated that sediment transport is influenced by wind direction and strength and the presence of vegetation. This study highlights that coastal dune systems are naturally unstable and dynamic environments, and that this complexity should be considered in the management of these features.

description: We present the results from simultaneous Chandra HETGS and RXTE observations of the microquasar GRS 1915+105 in its quasi-stable "soft state" (or State A) performed on 2007 August 14, several days after the state transition from "hard state" (State C). The X-ray flux increased with spectral hardening around the middle of the Chandra observation, after which the 67 Hz QPO became significant. The HETGS spectra reveal at least 32 narrow absorption lines from highly ionized ions including Ne, Mg, Si, S, Ar, Ca, Cr, Mn, Fe, whose features are the deepest among those ever observed with Chandra from this source. We find that the absorber has outflow velocities of ~150 and ~500 km s^{-1} with a line-of-sight velocity dispersion of ~70 and ~200 km s^{-1} for the Si XIV and Fe XXVI ions, respectively. The larger velocity and its dispersion in heavier ions indicate that the wind has a non-uniform dynamical structure along the line-of-sight. The location of the absorber is estimated at ~(1-3)x10^5 r_g (r_g is the gravitational radius) from the source, consistent with thermally and/or radiation driven winds. The continuum spectra obtained with RXTE in the 3-25 keV band can be well described with a thermal Comptonization with an electron temperature of ~4 keV and an optical depth of ~5 from seed photons from the standard disk extending down to (4-7) r_g. In this interpretation, most of the radiation energy is produced in the Comptonization corona, which completely covers the inner part of the disk. A broad (1σwidth of ~0.2 keV) iron-K emission line and a smeared edge feature are detected, which can be explained by reflection from the accretion disk at radii larger than 400 r_g.

description: Smoothing is an estimation technique that takes into account both past and future observations, and can be more accurate than filtering alone. In this Letter, a quantum theory of smoothing is constructed using a time-symmetric formalism, thereby generalizing prior work on classical and quantum filtering, retrodiction, and smoothing. The proposed theory solves the important problem of optimally estimating classical Markov processes coupled to a quantum system under continuous measurements, and is thus expected to find major applications in future quantum sensing systems, such as gravitational wave detectors and atomic magnetometers.

description: The chemotactic pathway allows bacteria to respond and adapt to environmental changes, by tuning the tumbling and running motions that are due to clockwise and counterclockwise rotations of their flagella. The pathway is tightly regulated by feedback mechanisms governed by the phosphorylation and methylation of several proteins. In this paper, we present a detailed mechanistic model for chemotaxis, that considers all of its transmembrane and cytoplasmic components, and their mutual interactions. Stochastic simulations of the dynamics of a pivotal protein, CheYp, are performed by means of tau leaping algorithm. This approach is then used to investigate the interplay between the stochastic fluctuations of CheYp amount and the number of cellular flagella. Our results suggest that the combination of these factors might represent a relevant component for chemotaxis. Moreover, we study the pathway under various conditions, such as different methylation levels and ligand amounts, in order to test its adaptation response. Some issues for future work are finally discussed.

A pkp study of the earth's core using the warramunga seismic array

description: PKP core phases recorded at the U.K.A.E.A. - type seismic array, WRA, in Northern Territory, Australia over the distance range 113° to 176° are used to determine a velocity-depth model for the earth's core. Paper recordings played out at high speed (40 mm/sec) from analog magnetic tape with amplitude gain control and narrow bandpass filters provided the data available for analysis. Such data enabled precision measurement of relative times between seismic traces. Four distinct travel time branches were observed. Two of these are the well-known PKP[formula omitted] and PKP[formula omitted] branches which are trans- mitted through the outer and inner cores, respectively. The two additional branches are forerunners to the DF branch at distances less than 143°. In recent years, the existence of one of these branches designated PKP[formula omitted], has been accepted to account for ob-served precursors. However, the existence of a distinct second branch, designated PKP[formula omitted], has been a subject for debate. Since the precursor branches provide information about the "transition region" between the fluid outer core and the solid inner core, the identification in this study of two distinct sets of forerunners is of some importance. Traveltime and traveltime gradient (dT/d∆ ) measurements of each phase observed on the seismograms were made. The dT/d∆ values were measured by a least-squares technique. These measurements were strongly perturbed by structure beneath the array and it was necessary to correct for the effect by an empirical approach. The corrected dT/d∆ values were smoothed by the method of summary values and, for comparison, by a polynomial regression technique. The smoothed dT/d∆ values for all four branches were inverted by the Herglotz-Weichert method in order to obtain a velocity-depth model for the earth's core. The final velocity model, UBC1, determined in this manner was the one which gave the best fit to all observations in this study. Near a depth of 4000 km., UBC1 required a -slight reduction in the Jeffreys-Bullen (1940) velocities in order to obtain travel times that agreed with the observations for the outer core. The model exhibits three velocity discontinuities at depths 4393 km, 4810 km, and 5120 km. The magnitude of the velocity increases at the discontinuities are 0.10, 0.24 and 0.92 km/sec, respectively. These discontinuities define two shells surrounding the inner core. In the outermost shell, 417 km thick, the velocity gradient is near zero in magnitude. In the second shell, 300 km thick, the velocity gradient is slightly negative.

20 aastat maksasiirdamist Eestis
Creators: name: Väli, Toomas
Publisher: name: Eesti Arst

description: Taust ja eesmärk. Maksasiirdamine on maksapuudulikkuse ravis levinud meetod. Töö siht oli analüüsida aastatel 1999–2018 TÜ Kliinikumi kirurgiakliinikus siiratud maksaga haigete ravitulemusi.


Meetodid. Haiguslugude alusel analüüsiti retrospektiivselt maksasiirdamise ravitaktikat, esinenud komplikatsioone, nende ravi ja haigete siirdamisjärgset elulemust ning surmapõhjusi. Analüüsimisel eristati maksasiirdamise juurutamise perioodi aastatel 1999–2008 ning siirdamise arendamise perioodi aastatel 2008–2018.


Tulemused. Juurutamise perioodil võeti siirdamise ootelehele 34 patsienti, neist 75% suri ootelehel olles maksapuudulikkuse süvenemise tõttu. Maks siirati 8 patsiendile. Neist 10 aasta möödudes elas 4 patsienti, 10 aasta elulemus oli 50%. Arendamise perioodil oli ootelehel 96 haiget, neist 17% suri ootelehel olles, maks siirati 76 haigele. Siirdamise järel esines bakteriaalne infektsioon 30%-l patsientidest, koe äge äratõukereaktsioon 8%-l, operatsioonijärgseid biliaarseid tüsistusi oli 32%-l ning vaskulaarseid tüsistusi 18%-l patsientidest. Üldine letaalsus oli sel perioodil 26%, siirdamisjärgne ühe aasta elulemus 81% ja viie aasta elulemus 73%.


Järeldused. 1. Maksasiirdamise arendusperioodil meie töörühma saavutatud ravitulemused – suremus ootelehel olles, siirdamisjärgsete komplikatsioonide esinemine ning nende ennetuse ja ravi meetmed ning patsientide siirdamisjärgne elulemus – on võrdluses teiste analoogsete keskuste ravitulemustega samal tasemel. 2. TÜ Kliinikumis välja arendatud organisatsioonilised meetmed ning hea erialase kogemusega meditsiinipersonal võimaldavad tulemuslikult jätkata maksasiirdamisi ka järgnevatel aastatel.

description: Managing heterogeneous network systems is a difficult task because each of these networks has its own curious management system. These networks usually are constructed on independent management protocols which are not compatible with each other. This results in the coexistence of many management systems with different managing functions and services across enterprises. Incompatibility of different management systems makes management of whole system a very complex and often complicated job. Ideally, it is necessary to implement centralized metalevel management across distributed heterogeneous systems and their underlying supporting network systems where the information flow and guidance is provided via a single console or single operating panels which integrates all the management functions in spite of their individual protocols and structures. This paper attempts to provide a novel network management tool architecture which supports heterogeneous managements across many different architectural platforms. Furthermore, an architectural approach to integrate heterogeneous network is proposed. This architecture takes into account both wireless fixed and mobile nodes.

Year: 2019

description: Mitmete temporomandibulaarliigeste haiguste puhul ei ole konservatiivne ravi alati tulemusrikas. Kirurgilise ravi eesmärk on taastada anatoomilised struktuurid ja liigese funktsioon ning vähem tähtis ei ole ka väljanägemise taastamine. Kirurgilised ravimeetodid oma erinevate võimalustega parandavad oluliselt patsientide elukvaliteeti, vähendades valu ja parandades võimet suud avada. Alalõualiigese kirurgilise ravi meetodeid on mitu: artrotsentees, artroskoopia, artrotoomia ja artroplastika, diski operatsioonid ning endoproteesimine. Kirurgilise ravi vastunäidustuseks on äge infektsioon ning raske funktsioonihäire, näiteks bruksism. Operatsiooni ei tohi teha ka kolju kasvamise perioodil. Võimalusi alalõualuuliigese haiguslike seisundite kõrvaldamiseks on mitu. Õige diagnoos ja sobiva ravimeetodi valik ning koostöö eriarstidega tagab temporomandibulaarliigese funktsiooni taastumise.

description: We combine the recent estimate of the contribution of galaxies to the 3.6 micron intensity of the extragalactic background light (EBL) with optical and near-infrared (IR) galaxy counts to set new limits on intrinsic spectra of some of the most distant TeV blazars 1ES 0229+200, 1ES 1218+30.4, and 1ES 1101-232, located at redshifts 0.1396, 0.182, and 0.186, respectively. The new lower limit on the 3.6 micron EBL intensity is significantly higher than the previous one set by the cumulative emission from resolved Spitzer galaxies. Correcting for attenuation by the revised EBL, we show that the differential spectral index of the intrinsic spectrum of the three blazars is 1.28 +- 0.20 or harder. These results present blazar emission models with the challenge of producing extremely hard intrinsic spectra in the sub-TeV to multi-TeV regime. These results also question the reliability of recently derived upper limits on the near-IR EBL intensity that are solely based on the assumption that intrinsic blazar spectra should not be harder than 1.5.

description: We consider two families of commuting Hamiltonians on the cotangent bundle of the group GL(n,C), and show that upon an appropriate single symplectic reduction they descend to the spectral invariants of the hyperbolic Sutherland and of the rational Ruijsenaars-Schneider Lax matrices, respectively. The duality symplectomorphism between these two integrable models, that was constructed by Ruijsenaars using direct methods, can be then interpreted geometrically simply as a gauge transformation connecting two cross sections of the orbits of the reduction group.

Neutrino masses, the cosmological constant and a stable universe in a Randall-Sundrum scenario

description: The Randall-Sundrum model of warped geometry in a five-dimensional scenario, aimed at explaining the hierarchy between the Planck and electroweak scales, is intrinsically unstable in its minimal form due to negative tension of the visible brane. A proposed solution to the problem yields a negative cosmological constant in four dimensions. We show that this wrong-sign cosmological constant is restricted to small values, therefore requiring less cancellation from hitherto unknown physics, if bulk neutrinos are postulated to explain the observed neutrino mass pattern. Thus neutrino masses, a stable Tev-brane configuration and new physics in the context of the cosmological constant get rather suggestively connected by the same thread.

description: The large scatters of luminosity relations of gamma-ray bursts (GRBs) have been one of the most important reasons that prevent the extensive applications of GRBs in cosmology. In this paper, we extend the two-dimensional (2D) luminosity relations with $τ_{\mathrm{lag}}$, $V$, $E_{\mathrm{peak}}$, and $τ_{\mathrm{RT}}$ as the luminosity indicators to three dimensions (3D) using the same set of luminosity indicators to explore the possibility of decreasing the intrinsic scatters. We find that, for the 3D luminosity relations between the luminosity and an energy scale ($E_{\mathrm{peak}}$) and a time scale ($τ_{\mathrm{lag}}$ or $τ_{\mathrm{RT}}$), their intrinsic scatters are considerably smaller than those of corresponding 2D luminosity relations. Enlightened by the result and the definition of the luminosity (energy released in units of time), we discussed possible reasons behind, which may give us helpful suggestions on seeking more precise luminosity relations for GRBs in the future.
