Subjects: subject: High Energy Physics - Phenomenology (hep-ph)
subject: FOS: Physical sciences

description: Production of doubly charged Higgs bosons via the s-channel process e-e- -> H-- -> l-l- at future linear collider energies is studied by taking into account initial state radiation (ISR) and beamstrahlung (ISR + BS), final state radiation (FSR) and detector smearing effects. The discovery bounds of lepton flavour conserving and violating couplings are obtained for doubly charged Higgs bosons. It is found that future linear colliders with centre of mass energies and will be able to probe the doubly charged Higgs bosons with diagonal couplings down to 10^-4 and 10^-3, respectively.

description: A model investigating the role of geometry on the alpha dose rate of spent nuclear fuel has been developed. This novel approach utilises a new piecewise function to describe the probability of alpha escape as a function of particulate radius, decay range within the material, and position from the surface. The alpha dose rates were produced for particulates of radii 1 $μ$m to 10 mm, showing considerable changes in the 1 $μ$m to 50 $μ$m range. Results indicate that for decreasing particulate sizes, approaching radii equal to or less than the range of the $α$-particle within the fuel, there is a significant increase in the rate of energy emitted per unit mass of fuel material. The influence of geometry is more significant for smaller radii, showing clear differences in dose rate curves below 50 $μ$m. These considerations are essential for any future accurate prediction of the dissolution rates and hydrogen gas release, driven by the radiolytic yields of particulate spent nuclear fuel.

Las Inquisiciones de Jorge Edwards
Creators: name: Schulz, Bernhardt R.
Publisher: name: University of British Columbia
Year: 2008

description: This work studies the extent to which the novels written by Jorge Edwards between 1973 and 1987 respond to the historical Chilean context that they seem to address, openly in some instances and evasively in others. It examines the way in which the novelist represents the Chilean situation under the dictatorship of Pinochet. In the novels, Los convidados de piedra (1978), Elmuseo de cera (1981), La muier imaginaria (1985) and Elanfitri On (1987), not only is the apparent decadence of asocial class revealed, but also the regenerative capacity of this class to perpetuate its dominance in society. The analysis of Edwards' works written during the dictatorship allows the possibility of comprehending the historical reality within the fiction through some themes: Chileanhistory, its culmination in the 1973 military coup and its aftermath, the decline of the bourgeois way of life, the status of women in Chile, and the problems of exile. To study the dialogue between the novel and society, and to reflect on the writer's role in facing the conflicts of his time, an eclectic methodology has been used which incorporates elements of narratology, Bakhtin's dialogism, sociology and history. These elements lead to further questioning rather than offering categorical answers; Edwards' own voice is used frequently to contrast or to clarify some aspects of his works. With the study of Edwards as an intellectual and with the review of his novels, this dissertation concludes that the Chilean writer shows a constant preoccupation with Chilean society. Moreover, his writings suggest that the causes of the dictatorship are anchored in an unresolved distant past. This explains the ironic gaze that questions the upper class and its origins from within. The voices of the novels are also ironic and reveal a rejection of the self-bestowed historical importance of the upper class. Finally, this study underlines the role the author has assigned to himself by converting the act of writing into an authentic personal mission.

description: In this paper we prove new constructive coercivity estimates for the Boltzmann collision operator without cutoff, that is for long-range interactions. In particular we give a generalized sufficient condition for the existence of a spectral gap which involves both the growth behavior of the collision kernel at large relative velocities and its singular behavior at grazing and frontal collisions. It provides in particular existence of a spectral gap and estimates on it for interactions deriving from the hard potentials $ϕ(r) = r^{-(s−1)}$, $s \ge 5$ or the so-called moderately soft potentials $ϕ(r) = r^{−(s−1)}$, $3 < s < 5$, (without angular cutoff). In particular this paper recovers (by constructive means), improves and extends previous results of Pao [46]. We also obtain constructive coercivity estimates for the Landau collision operator for the optimal coercivity norm pointed out in [34] and we formulate a conjecture about a unified necessary and sufficient condition for the existence of a spectral gap for Boltzmann and Landau linearized collision operators.

description: To assess healthcare costs and hospitalization rates associated with rifaximin therapy versus lactulose alone among patients at risk for hepatic encephalopathy (HE). IBM Marketscan Commercial and Optum’s de-identified Clinformatics Data Mart databases were used separately to identify commercially insured HE patients treated with rifaximin or lactulose alone, using an algorithm developed with clinical experts. HE-related hospitalizations were defined based on an algorithm using diagnosis codes and diagnosis-related group codes. HE-related/all-cause hospital admissions/days and healthcare costs were compared between rifaximin and lactulose episodes using incidence rate ratios and adjusted cost differences. In Marketscan, there were 13,515 [Optum: 5,217] rifaximin episodes and 9,946 [4,897] lactulose alone episodes included. Yearly rates of HE-related hospital admissions decreased by 33% [34%] when treated with rifaximin versus lactulose alone, and rates of HE-related hospital days similarly decreased by 43% [57%]. Yearly rates of all-cause hospital admissions decreased by 27% [27%]; rates of all-cause hospital days decreased by 33% [37%] during rifaximin episodes versus lactulose alone. This translated to $2,417 [$2,301] and $173 [$397] lower total mean medical costs and HE-related hospital costs per-patient-per-month, respectively (p Patients incurred significantly lower rates of HE-related and all-cause hospitalizations during rifaximin versus lactulose episodes, resulting in lower facility and professional costs. Cost savings may be possible if rifaximin adherence is improved in HE patients. The study is subject to limitations common to claims-based analyses.

description: The human genome contains instructions to transcribe more than 200,000 RNAs. However, many RNA transcripts are generated from the same gene, resulting in alternative isoforms that are highly similar and that remain difficult to quantify. To evaluate the ability to study RNA transcript expression, we profiled seven human cell lines with five different RNA-sequencing protocols, including short-read cDNA, Nanopore long-read direct RNA, amplification-free direct cDNA and PCR-amplified cDNA sequencing, and PacBio IsoSeq, with multiple spike-in controls, and additional transcriptome-wide N6-methyladenosine profiling data. We describe differences in read length, coverage, throughput and transcript expression, reporting that long-read RNA sequencing more robustly identifies major isoforms. We illustrate the value of the SG-NEx data to identify alternative isoforms, novel transcripts, fusion transcripts and N6-methyladenosine RNA modifications. Together, the SG-NEx data provide a comprehensive resource enabling the development and benchmarking of computational methods for profiling complex transcriptional events at isoform-level resolution.

description: Very recently, increasing attention has been focused on non-Abelian topological charges, e.g. the quaternion group Q8. Different from Abelian topological band insulators, these systems involve multiple tangled bulk bandgaps and support non-trivial edge states that manifest the non-Abelian topological features. Furthermore, a system with even or odd number of bands will exhibit significant difference in non-Abelian topological classifications. Up to now, there is scant research investigating the even-band non-Abelian topological insulators. Here, we both theoretically explored and experimentally realized a four-band PT (inversion and time-reversal) symmetric system, where two new classes of topological charges as well as edge states are comprehensively studied. We illustrate their difference from four-dimensional rotation senses on the stereographically projected Clifford tori. We show the evolution of bulk topology by extending the 1D Hamiltonian onto a 2D plane and provide the accompanying edge state distributions following an analytical method. Our work presents an exhaustive study of four-band non-Abelian topological insulators and paves the way to other even band systems.

description: In recent years, there have been significant advances in multi-messenger astronomy due to the discovery of the first, and so far only confirmed, gravitational wave event with a simultaneous electromagnetic (EM) counterpart, as well as improvements in numerical simulations, gravitational wave (GW) detectors, and transient astronomy. This has led to the exciting possibility of performing joint analyses of the GW and EM data, providing additional constraints on fundamental properties of the binary progenitor and merger remnant. Here, we present a new Bayesian framework that allows inference of these properties, while taking into account the systematic modeling uncertainties that arise when mapping from GW binary progenitor properties to photometric light curves. We extend the relative binning method presented in Zackay et al. (2018) to include extrinsic GW parameters for fast analysis of the GW signal. The focus of our EM framework is on light curves arising from r-process nucleosynthesis in the ejected material during and after merger, the so called kilonova, and particularly on black hole - neutron star systems. As a case study, we examine the recent detection of GW190425, where the primary object is consistent with being either a black hole (BH) or a neutron star (NS). We show quantitatively how improved mapping between binary progenitor and outflow properties, and/or an increase in EM data quantity and quality are required in order to break degeneracies in the fundamental source parameters.

description: Τhe subject of this thesis is the study, design and construction of a system which is able to recognize the position of a moving subject in real time, using an AVR microcontroller of the company Atmel, to control a moving subject through distance and to send messages over mobile networks. Particularly, special type sensors check the position of the moving subject in real time. For the simulation, a maquette 120x110cm is constructed and a train with a model scale of 1:150 is used as a moving subject. The commands given to the sensors are driven to the microcontroller. This process is generating messages which are displayed on screens. Also, the complete control of the model train, in order to activate or deactivate it, is realized through distance. Furthermore, the microcontroller activates the inputs of a global system for mobile communication GSM which is sending text and audio messages at the appropriate time. The power supply is realized by using 12V batteries in combination with a constant voltage converter of 5V.

description: Solar grade silicon (SoG-Si) is a key material for the development of crystalline silicon photovoltaics (PV), which is expected to reach the tera-watt level in the next years and around 50TW in 2050. Upgraded metallurgical grade silicon (UMG-Si) has already demonstrated to be a viable alternative to standard polysilicon in terms of cost and quality. This study presents the life cycle assessment (LCA) of UMG obtained by the FerroSolar process. Moreover, it shows the environmental impacts of PV modules and electricity generation based on this material. For this, an exhaustive review of the life cycle inventory (LCI) of PV value chain, from metallurgical grade silicon (MG-Si) down to electricity generation, has been carried out updating inputs for all processes. The Balance of System (BoS) has also been updated with real state of the art data for a fixed open ground large PV site (100 MW). Two different electricity mixes, with low and high carbon intensities, have been considered. The results reveal that for PV electricity generation using UMG instead of polysilicon leads to an overall reduction of Climate change (CC) emissions of over 20%, along with an improvement of the Energy Payback Time (EPBT) of 25%, achieving significantly low values, 12 gCO2eq / kWhe and 0.52 years, respectively. Moreover, it is shown that UMG silicon feedstock is not the main contributor to the carbon and energy footprint of the produced electricity, leaving the first place to PV module manufacturing.

Μια τέτοια έρευνα είναι και η παρούσα μελέτη, που έχει ως σκοπό την γενική παρουσίαση της αλβανικής ιστορίας κατά την περίοδο του υπαρκτού σοσιαλισμού, καθώς επίσης και την ανάδειξη της θρησκευτικής πολιτικής που ακολουθήθηκε στην Λαϊκή και Σοσιαλιστική Δημοκρατία της Αλβανίας από το 1945, όταν και αναδείχθηκε το Κομμουνιστικό Κόμμα στην εξουσία, μέχρι και την ολοκληρωτική πτώση του το 1991. Πιο συγκεκριμένα, εξετάσαμε την ιστορική κατάσταση όλων των θρησκευτικών κοινοτήτων από την περίοδο του καθεστώτος του βασιλιά Ζώγου, μέχρι και το τέλος του Δευτέρου Παγκοσμίου Πολέμου. Στη συνέχεια παρουσιάσαμε αναλυτικά την αναγκαστική συμβίωση μεταξύ σοσιαλιστικού Κράτους και θρησκευτικών κοινοτήτων, την σχέση της χώρας με την Γιουγκοσλαβία, την πλήρη επιρροή της Ε.Σ.Σ.Δ. και την συνεργασία της με την Κίνα. Ακόμη αναφερθήκαμε αναλυτικά στην περιβόητη πολιτιστική επανάσταση που στα πλαίσια της απαγορεύτηκε πλήρως η θρησκεία. Ασχοληθήκαμε επιπλέον με την εποχή της σκληρής απομόνωσης της χώρας από τον υπόλοιπο κόσμο, τις πρώτες δειλές μεταρρυθμίσεις, την πτώση του καθεστώτος αλλά και την αποκατάσταση όλων των θρησκειών.
description: In the recent years the systematic study of the history of socialist countries has spread in many research fields, paving the way among other, new paths in research and science. Such a research is the present study, which aims at the broad presentation of the Albanian history amid the period of socialism, as well as the emergence of the religious policy that followed in the People's Socialist Republic of Albania since 1945, from when the Communist Party rised into power, up until its outright decline in 1991.More explicitly, we examined the historical status of all religious communities from the regime's period of king Zogu, up until the end of the Second World War. Subsequently, we presented in thorough detail the enforced coexistence between the socialist state and religious communities, the relationship of the country with Yugoslavia, the complete influence of Moscow, and its cooperation with China. Further, we discussed in detail of the infamous cultural revolution by which religion was completely banned . Even further, we dealt with the era of cruel isolation of the country from the outside world, the first timid reforms, the decline of the regime and the restoration of all religions

description: Commercial weather stations can effectively collect weather data for a specified area. However, their ground sensors limit the amount of data that can be logged, thus failing to collect precise meteorological data in a local area such as a micro-scale region. This happens because weather conditions at a micro-scale region can vary greatly even with small altitude changes. For now, drone operators must check the local weather conditions to ensure a safe and successful flight. This task is often a part of pre-flight preparations. Since flight conditions (and most important flight safety) are greatly affected by weather, drone operators need a more accurate localized weather map reading for the flight area. In this paper, we present the Arduino Sensor Integrated Drone (ASID) with a built-in meteorological station that logs the weather conditions in the vertical area where the drone will be deployed. ASID is an autonomous drone-based system that monitors weather conditions for pre-flight preparation. The operation of the ASID system is based on the Arduino microcontroller running automatic flight profiles to record meteorological data such as temperature, barometric pressure, humidity, etc. The Arduino microcontroller also takes photos of the horizon for an objective assessment of the visibility, the base, and the number of clouds.

description: In an alternate, post-environmental-catastrophe United States, young artist Clare Dunne is depressed, underpaid, and struggling to get by. But when she’s diagnosed with IMAS, an incurable and fatal disease, she’ll do anything to hold on to her life. A chance presents itself in the form of Mite Health, a biotech startup that offers Clare free treatment under one condition: she leave home to enroll in a clinical trial of an experimental animal-derived therapy. Though initially successful, the treatment comes with devastating side effects: most distressing is the thick grey fur that Clare and the other patients begin to sprout — and that’s just the beginning. Meanwhile, second-grade social outcast Estie is an animal-lover who hasn’t felt well for a while. As her symptoms progress, and she too is diagnosed with IMAS, her path becomes intertwined with Clare’s and the two become inextricably linked both to each other and the nonhuman world around them.
Use of the cellulose-binding domain of a cellulase from cellulomonas fimi for affinity purification of fusion preteins
Creators: name: Greenwood, Jeffrey M.
Publisher: name: University of British Columbia
Year: 2008

description: This study describes the use of a cellulose-binding domain (CBD) from a bacterial cellulase as an affinity tag for purification of heterologous proteins. The CBD of endoglucanase A (CenA) from Cellulomonas fimi is an N-terminal domain comprising amino acids. CenA binds strongly to cellulose, and the CBD retains this function when separated from its cognate catalytic domain by proteolysis or genetic manipulation. A series of fusions between CenA and alkaline phosphatase from Escherichia coli (PhoA) were generated using TnphoA, and were screened for binding to cellulose. CenA-PhoA fusion proteins containing an intact CBD bind to cellulose, while those missing 28 or 68 C-terminal amino acids from the CBD do not. Similarly, deletions of 18 or 44 amino acids from the N-terminus of the CBD abolish binding to cellulose. This is the first demonstration of a CBD retaining its function when fused to a heterologous polypeptide. Just one CBD is sufficient to bind dimeric alkaline phosphatase to cellulose. Engineered CenA-PhoA fusion proteins are purified in a single step by affinity chromatography on cellulose, with distilled water elution. The CBD was removed by specific proteolytic cleavage with Factor Xa or by a C. fimi serine protease. CBD fusions with human interleukin 2 (IL2) were constructed, but are predominantly insoluble and extensively degraded on expression in E. coli. However, the fusion polypeptides can still be purified by binding to cellulose.

description: Nano-optic imagers that modulate light at sub-wavelength scales could unlock unprecedented applications in diverse domains ranging from robotics to medicine. Although metasurface optics offer a path to such ultra-small imagers, existing methods have achieved image quality far worse than bulky refractive alternatives, fundamentally limited by aberrations at large apertures and low f-numbers. In this work, we close this performance gap by presenting the first neural nano-optics. We devise a fully differentiable learning method that learns a metasurface physical structure in conjunction with a novel, neural feature-based image reconstruction algorithm. Experimentally validating the proposed method, we achieve an order of magnitude lower reconstruction error. As such, we present the first high-quality, nano-optic imager that combines the widest field of view for full-color metasurface operation while simultaneously achieving the largest demonstrated 0.5 mm, f/2 aperture.

description: A major upgrade of the ALICE experiment is in progress and will result in high-rate data taking during LHC Run 3 (2022-2024). The LHC interaction rate at Point 2 where the ALICE experiment is located will be increased to $50\ \mathrm{kHz}$ in Pb--Pb collisions and $1\ \mathrm{MHz}$ in pp collisions. The ALICE experiment will be able to read out data at these interaction rates leading to an increase of the collected luminosity by a factor of up to about 100 with respect to LHC Runs 1 and 2. To satisfy these requirements, a new readout system has been developed for most of the ALICE detectors, allowing the full readout of the data at the required interaction rates without the need for a hardware trigger selection. A novel trigger and timing distribution system will be implemented, based on Passive Optical Network (PON) and GigaBit Transceiver (GBT) technology. To assure backward compatibility a triggered mode based on RD12 Trigger-Timing-Control (TTC) technology, as used in the previous LHC runs, will be maintained and re-implemented under the new Central Trigger System (CTS). A new universal ALICE Trigger Board (ATB) based on the Xilinx Kintex Ultrascale FPGA has been designed to function as a Central Trigger Processor (CTP), Local Trigger Unit (LTU), and monitoring interfaces. In this paper, this new hybrid multilevel system with continuous readout will be described, together with the triggering mechanism and algorithms. An overview of the CTS, the design of the ATB and the different communication protocols will be presented.

description: Central issues of the Dirac constraint formalism are discussed in relation to the algorithmic methods of commutative algebra based on the Groebner basis techniques. For a wide class of finite dimensional polynomial degenerate Lagrangian systems, we describe an algorithmic scheme of computation of the complete set of constraints, their separation into subsets of first and second class constraints as well as the construction of a generator of local symmetry transformations. The proposed scheme is exemplified by considering the so-called light-cone Yang-Mills mechanics with an SU(2) gauge structure group.

description: Synchrotron radio emission from non-relativistic jets powered by massive protostars has been reported, indicating the presence of relativistic electrons and magnetic fields of strength ~0.3-5 mG. We study diffusive shock acceleration and magnetic field amplification in protostellar jets with speeds between 300 and 1500 km/s. We show that the magnetic field in the synchrotron emitter can be amplified by the non-resonant hybrid (Bell) instability excited by the cosmic-ray streaming. By combining the synchrotron data with basic theory of Bell instability we estimate the magnetic field in the synchrotron emitter and the maximum energy of protons. Protons can achieve maximum energies in the range 0.04-0.65 TeV and emit gamma rays in their interaction with matter fields. We predict detectable levels of gamma rays in IRAS 16547-5247 and IRAS 16848-4603. The gamma ray flux can be significantly enhanced by the gas mixing due to Rayleigh-Taylor instability. The detection of this radiation by the Fermi satellite in the GeV domain and the forthcoming Cherenkov Telescope Array at higher energies may open a new window to study the formation of massive stars, as well as diffusive acceleration and magnetic field amplification in shocks with velocities of about 1000 km/s.

description: Linear first order systems of partial differential equations of the form $\nabla f = M\nabla g,$ where $M$ is a constant matrix, are studied on vector spaces over the fields of real and complex numbers, respectively. The Cauchy--Riemann equations belong to this class. We introduce a bilinear $*$-multiplication on the solution space, which plays the role of a nonlinear superposition principle, that allows for algebraic construction of new solutions from known solutions. The gradient equations $\nabla f = M\nabla g$ constitute only a simple special case of a much larger class of systems of partial differential equations which admit a bilinear multiplication on the solution space, but we prove that any gradient equation has the exceptional property that the general analytic solution can be expressed through power series of certain simple solutions, with respect to the $*$-multiplication.

description: We describe the application of Semantic Segmentation by using the Self Organizing Map technique to an high spatial and spectral resolution dataset acquired along the H$α$ line at 656.28 nm by the Interferometric Bi-dimensional Spectrometer installed at the focus plane of the Dunn Solar Telescope. This machine learning approach allowed us to identify several features corresponding to the main structures of the solar photosphere and chromosphere. The obtained results show the capability and flexibility of this method to identifying and analyzing the fine structures which characterize the solar activity in the low atmosphere. This is a first successful application of the SOM technique to astrophysical data sets.

Constraints on superdense preon stars and their formation scenarios

Publisher: name: arXiv

Subjects: subject: Astrophysics (astro-ph)

description: We address in this work the general features of a possible compact stars composed by elementary fermions beyond the quark level. The {\it locus} of these hypothetic objects in the mass-radius plane is constructed for the maximum mass (minimum radius) of the sequence of models in terms of a compositeness scale only, and in fact this approach applies for any composite model postulating fermions at or beyond the preon level. We point out a constraint on the preon mass arising from the applicability of the General Relativity structure equations, leading to the questioning of the hypothesis of light preons if the preon scale is high, provided classical compact objects are enforced. Some remarks on the existence of superdense stars of astrophysical and primordial origin are made and discussed.

Heat flux deposition on plasma-facing components using a convective model with ripple and Shafranov shift

description: A heat flux deposition code is a very useful tool for the design of plasma-facing components. The classical cosine model representative of the convective parallel heat flux was coded within the standard finite element code of the CEA Castem 2000. Two perturbations to the idealised magnetic surfaces were taken into account: the Shafranov shift and the ripple of the toroidal magnetic field. The calculation scheme -- named Tokaflu -- was confronted to previous computations on bottom modular limiters and to experiments on the inner first wall. The code was used to optimise the shape of future plasma-facing components in Tore Supra designed for the CIEL project, namely the toroidal pumped limiter and its neutralisers. Developments are under way to include the shadowing of the components, other power deposition schemes and possibly later plasma sections other than circular.
The effect of soothing music on neonatal behavioural states in the hospital newborn nursery
Creators: name: Kaminski, June L.
Publisher: name: University of British Columbia
Year: 2008

description: This study was designed to test the effect of soothing music on the number of high arousal neonatal behavioural states and the frequency of behavioural state change within the hospital newborn nursery. The theoretical framework for this study was drawn from theories related to newborn behavioural states, environmental influences on newborns, psychophysiologic effects of music and music as a health intervention. This study used a quasi-experimental, one sample, pretest, posttest design in which the subjects served as their own controls. The results were then analyzed using a one-tailed, McNemar's test (alpha < .05) specific for related small samples when nominal scale data are gathered. The sample consisted of twenty subjects observed in a large tertiary care hospital in Western Canada. The subjects ranged in age from 24 to 57 hours old, were 36 to 42 weeks gestational age, weighed 2860 to 4160 grams at birth, and had Apgar scores ranging from 9 to 10 at five minutes postbirth. There were 8 females and 12 males. All were Caucasian and all were born vaginally without complications. All but two were breastfed. The subjects were observed for a total of four hours each, two hours in the normal nursery environment and another two hours with the addition of selected soothing music. All observations took place between 2400 and 0600hours. There was a significant difference at the alpha < .05level in the number of high arousal states (Nonalert Waking and Crying) between the control and experimental observations. The control group exhibited significantly more high arousal states than the experimental group did. The score obtained from comparing the proportion of high arousal states between the two observations was 2.36, p < .01, significantly higher than the score of 1.65 needed to be significant at alpha < .05. There was also a statistically significant difference in the number of state changes and in the z score of 2.93, p < .001 for state lability. The control group demonstrated significantly more state changes than the experimental group did. With a sample size of twenty, conclusions are tentative. The findings suggest that music may be useful to newborns adapting to extra uterine existence within a nursery setting. Interventions intended to reduce the frequency of high arousal states in newborns while in the nursery are the responsibility of nurses. Nursing and patient education should also address the possible use of music with babies exhibiting high arousal behavioural states. The results of this study suggest areas for replication and further study.
Dynamic approach for micromagnetics close to the Curie temperature

description: In conventional micromagnetism magnetic domain configurations are calculated based on a continuum theory for the magnetization which is assumed to be of constant length in time and space. Dynamics is usually described with the Landau-Lifshitz-Gilbert (LLG) equation the stochastic variant of which includes finite temperatures. Using simulation techniques with atomistic resolution we show that this conventional micromagnetic approach fails for higher temperatures since we find two effects which cannot be described in terms of the LLG equation: i) an enhanced damping when approaching the Curie temperature and, ii) a magnetization magnitude that is not constant in time. We show, however, that both of these effects are naturally described by the Landau-Lifshitz-Bloch equation which links the LLG equation with the theory of critical phenomena and turns out to be a more realistic equation for magnetization dynamics at elevated temperatures.

description: The failure of roughness parameters to predict surface properties stems from their inherent scale-dependence; in other words, the measured value depends on the way it was measured. Here we take advantage of this scale-dependence to develop a new framework for characterizing rough surfaces: the Scale-Dependent Roughness Parameters (SDRP) analysis that yields slope, curvature and higher-order derivatives of surface topography at many scales, even on a single topography measurement. We demonstrate the relationship between SDRP and other common statistical methods for analyzing surfaces: the height-difference autocorrelation function (ACF), variable bandwidth methods (VBMs) and the power spectral density (PSD). We use computer-generated and measured topographies to demonstrate the benefits of SDRP analysis, including: novel metrics for characterizing surfaces across scales, and the detection of measurement artifacts. The SDRP is a generalized framework for scale-dependent analysis of surface topography that yields metrics that are intuitively understandable.

description: Using the opacity expansion technique we investigate the photon radiation and dilepton production induced by multiple rescattering as energetic parton jet passing through the strong interacting medium. The real photon radiation and dilepton invariant-mass spectrums of the bremsstrahlung contribution from an energetic quark jet are presented. The leading contribution of total energy loss by photon emmision in medium of a higher energy quark jet is found to be proportional to the jet energy and has a linear dependence on the thickness of the nuclear target. The rescattering contribution for the dilepton is important only for small value of the invariant-mass and for the not so fast jet. The contribution fraction of the dilepton induced by rescattering in medium is found to be nearly a constant when the ratio of jet energy to Debye screening mass $E/μ$ is large.
