Subjects: classificationCode: 39
subject: Education

description: This research examined the quality of Early Childhood Education and Care (ECEC) policy and practice in Ireland. According to the OECD (2001, 125, emphasis in original), there are eight key elements of ECEC policy which “are likely to promote equitable access to quality ECEC”. These are:  A systemic and integrated approach to policy development and mplementation  A strong and equal partnership with the education system  A universal approach to access, with particular attention to children in need of special support  Substantial public investment in ECEC services and infrastructure is necessary  A participatory approach to quality improvement and assurance  Staff in all forms of provision require appropriate training and working conditions  Systematic attention to monitoring and data collection  A stable framework and long-term agenda for research and evaluation as part of a continuous improvement process. Utilising the eight components of ECEC quality identified by the OECD (2001), Irish efforts to achieve quality ECEC were examined. It was noted that while Ireland is making progress in relation to each of the OECD’s eight components of quality, Irish approaches to ECEC remain fragmented and room for improvement continues to exist. In order to examine the standard of ECEC provision in Ireland both the Early Childhood Environment Rating Scale–Revised and Extended (ECERS-R & E) were applied to twenty-six sessional ECEC services. Although the sample size was small, the ECERS-R & E data provides a unique snapshot into the quality of sessional ECEC services. The findings from the ECERS-R & E data indicate that the quality of the provision observed varied both across and also within services.
 Through an analysis of Irish approaches to ECEC this research makes a significant contribution to current understandings of ECEC quality. In particular this research highlights some of the areas of both ECEC policy and practice that may need further improvement in order to meet internationally recognised standards of quality.
Semiparametric forecasting and filtering: correcting low-dimensional model error in parametric models

description: Semiparametric forecasting and filtering are introduced as a method of addressing model errors arising from unresolved physical phenomena. While traditional parametric models are able to learn high-dimensional systems from small data sets, their rigid parametric structure makes them vulnerable to model error. On the other hand, nonparametric models have a very flexible structure, but they suffer from the curse-of-dimensionality and are not practical for high-dimensional systems. The semiparametric approach loosens the structure of a parametric model by fitting a data-driven nonparametric model for the parameters. Given a parametric dynamical model and a noisy data set of historical observations, an adaptive Kalman filter is used to extract a time-series of the parameter values. A nonparametric forecasting model for the parameters is built by projecting the discrete shift map onto a data-driven basis of smooth functions. Existing techniques for filtering and forecasting algorithms extend naturally to the semiparametric model which can effectively compensate for model error, with forecasting skill approaching that of the perfect model. Semiparametric forecasting and filtering are a generalization of statistical semiparametric models to time-dependent distributions evolving under dynamical systems.

description: This work investigates the joint design of fronthaul compression and precoding for the downlink of Cloud Radio Access Networks (C-RANs). In a C-RAN, a central unit (CU) performs the baseband processing for a cluster of radio units (RUs) that receive compressed baseband samples from the CU through low-latency fronthaul links. Most previous works on the design of fronthaul compression and precoding assume constant channels and instantaneous channel state information (CSI) at the CU. This work, in contrast, concentrates on a more practical scenario with block-ergodic channels and considers either instantaneous or stochastic CSI at the CU. Moreover, the analysis encompasses both the Compression-After-Precoding (CAP) and the Compression-Before-Precoding (CBP) schemes. With the CAP approach, which is the standard C-RAN solution, the CU performs channel coding and precoding and then the CU compresses and forwards the resulting baseband signals on the fronthaul links to the RUs. With the CBP scheme, instead, the CU does not perform precoding but rather forwards separately the information messages of a subset of mobile stations (MSs) along with the compressed precoding matrices to the each RU, which then performs precoding. Optimization algorithms over fronthaul compression and precoding for both CAP and CBP are proposed that are based on a stochastic successive upper-bound minimization approach. Via numerical results, the relative merits of the two strategies under either instantaneous or stochastic CSI are evaluated as a function of system parameters such as fronthaul capacity and channel coherence time.

description: In this paper, we propose a compressed sensing (CS) framework that consists of three parts: a unit-norm tight frame (UTF), a random diagonal matrix and a column-wise orthonormal matrix. We prove that this structure satisfies the restricted isometry property (RIP) with high probability if the number of measurements $m = O(s \log^2s \log^2n)$ for $s$-sparse signals of length $n$ and if the column-wise orthonormal matrix is bounded. Some existing structured sensing models can be studied under this framework, which then gives tighter bounds on the required number of measurements to satisfy the RIP. More importantly, we propose several structured sensing models by appealing to this unified framework, such as a general sensing model with arbitrary/determinisic subsamplers, a fast and efficient block compressed sensing scheme, and structured sensing matrices with deterministic phase modulations, all of which can lead to improvements on practical applications. In particular, one of the constructions is applied to simplify the transceiver design of CS-based channel estimation for orthogonal frequency division multiplexing (OFDM) systems.

description: The broad line region (BLR) of luminous active galactic nuclei (AGN) is a prominent observational signature of the accretion flow around supermassive black holes, which can be used to measure their masses (M_BH) over cosmic history. Due to the <100 μas angular size of the BLR, current direct constraints on BLR kinematics are limited to those provided by reverberation mapping studies, which are most efficiently carried out on low-luminosity L and low-redshift z AGN. We analyze the possibility to measure the BLR size and study its kinematic structure using spectroastrometry, whereby one measures the spatial position centroid of emission line photons as a function of velocity. We calculate the expected spectroastrometric signal of a rotation-dominated BLR for various assumptions about the ratio of random to rotational motions, and the radial distribution of the BLR gas. We show that for hyper-luminous quasars at z < 2.5, the size of the low-ionization BLR can already be constrained with existing telescopes and adaptive optics systems, thus providing a novel method to spatially resolve the kinematics of the accretion flow at 10^3 -- 10^4 gravitational radii, and measure M_BH at the high-L end of the AGN family. With a 30m-class telescope, BLR spectroastrometry should be routinely detectable for much fainter quasars out to z ~ 6, and for various emission lines. This will enable kinematic M_BH measurements as a function of luminosity and redshift, providing a compelling science case for next generation telescopes.

description: We study the ground state quantum fragmentation in a mixture of a polar condensate and a ferromagnetic condensate when subject to an external magnetic field. We pay more attentions to the polar condensate and find that it will be less fragile in the mixture when perturbed by the magnetic field. Both atom numbers and the number fluctuations in the spin-0 component will keep in a high magnitude of order of $N$ when the magnetization of the system is increased. The role of the ferromagnetic condensate is to provide a uniform and stable background which can delay the rapid shrink of the 0-component population and make it possible to capture the \textquotedblleft super-fragmentation \textquotedblright. Our method has potential applications in measuring the inter-species spin-coupling interaction through adjusting the magnetic field.

description: The mobility of atoms, molecules and radicals in icy grain mantles regulate ice restructuring, desorption, and chemistry in astrophysical environments. Interstellar ices are dominated by H2O, and diffusion on external and internal (pore) surfaces of H2O-rich ices is therefore a key process to constrain. This study aims to quantify the diffusion kinetics and barrier of the abundant ice constituent CO into H2O dominated ices at low temperatures (15-23 K), by measuring the mixing rate of initially layered H2O(:CO2)/CO ices. The mixed fraction of CO as a function of time is determined by monitoring the shape of the infrared CO stretching band. Mixing is observed at all investigated temperatures on minute time scales, and can be ascribed to CO diffusion in H2O ice pores. The diffusion coefficient and final mixed fraction depend on ice temperature, porosity, thickness and composition. The experiments are analyzed by applying Fick's diffusion equation under the assumption that mixing is due to CO diffusion into an immobile H2O ice. The extracted energy barrier for CO diffusion into amorphous H2O ice is ~160 K. This is effectively a surface diffusion barrier. The derived barrier is low compared to current surface diffusion barriers in use in astrochemical models. Its adoption may significantly change the expected timescales for different ice processes in interstellar environments.

description: Die Erstellung dreidimensionaler Umgebungsmodelle ist eine fundamentale Aufgabe im Bereich des maschinellen Sehens. Rekonstruktionen sind für eine Reihe von Anwendungen von Nutzen, wie bei der Vermessung, dem Erhalt von Kulturgütern oder der Erstellung virtueller Welten in der Unterhaltungsindustrie. Im Bereich des automatischen Fahrens helfen sie bei der Bewältigung einer Vielzahl an Herausforderungen. Dazu gehören Lokalisierung, das Annotieren großer Datensätze oder die vollautomatische Erstellung von Simulationsszenarien. Die Herausforderung bei der 3D Rekonstruktion ist die gemeinsame Schätzung von Sensorposen und einem Umgebunsmodell. Redundante und potenziell fehlerbehaftete Messungen verschiedener Sensoren müssen in eine gemeinsame Repräsentation der Welt integriert werden, um ein metrisch und photometrisch korrektes Modell zu erhalten. Gleichzeitig muss die Methode effizient Ressourcen nutzen, um Laufzeiten zu erreichen, welche die praktische Nutzung ermöglichen. In dieser Arbeit stellen wir ein Verfahren zur Rekonstruktion vor, das fähig ist, photorealistische 3D Rekonstruktionen großer Areale zu erstellen, die sich über mehrere Kilometer erstrecken. Entfernungsmessungen aus Laserscannern und Stereokamerasystemen werden zusammen mit Hilfe eines volumetrischen Rekonstruktionsverfahrens fusioniert. Ringschlüsse werden erkannt und als zusätzliche Bedingungen eingebracht, um eine global konsistente Karte zu erhalten. Das resultierende Gitternetz wird aus Kamerabildern texturiert, wobei die einzelnen Beobachtungen mit ihrer Güte gewichtet werden. Für eine nahtlose Erscheinung werden die unbekannten Belichtungszeiten und Parameter des optischen Systems mitgeschätzt und die Bilder entsprechend korrigiert. Wir evaluieren unsere Methode auf synthetischen Daten, realen Sensordaten unseres Versuchsfahrzeugs und öffentlich verfügbaren Datensätzen. Wir zeigen qualitative Ergebnisse großer innerstädtischer Bereiche, sowie quantitative Auswertungen der Fahrzeugtrajektorie und der Rekonstruktionsqualität. Zuletzt präsentieren wir mehrere Anwendungen und zeigen somit den Nutzen unserer Methode für Anwendungen im Bereich des automatischen Fahrens.

description: Exploring Einstein's theories of relativity in quantum systems, for example by using atomic clocks at high speeds can deepen our knowledge in physics. However, many challenges still remain on finding novel methods for detecting effects of gravity and of special relativity and their roles in light-matter interaction. Here we introduce a scheme of x-ray quantum optics that allows for a millimeter scale investigation of the relativistic redshift by directly probing a fixed nuclear crystal in Earth's gravitational field with x-rays. Alternatively, a compact rotating crystal can be used to force interacting x-rays to experience inhomogeneous clock tick rates in a crystal. We find that an association of gravitational or special-relativistic time dilation with quantum interference will be manifested by deflections of x-ray photons. Our protocol suggests a new and feasible tabletop solution for probing effects of gravity and special relativity in the quantum world.

Inside the black box: market mechanisms and the Paris Agreement on climate change
Creators: name: Buchan, Elizabeth
Publisher: name: The Australian National University
Year: 2016

description: This research explores the dynamic of the relationship between the formulation of Paris Agreement (PA), the next major multilateral solution to climate change under the United Nations Framework Convention on Climate Change (UNFCCC), and an increasingly prevalent policy instrument for reducing GHG emissions from anthropogenic sources, market mechanisms. Previous experiences have informed commentary on the value of market mechanisms including the rationale for their use a policy instrument, governance and political challenges faced in practice, and what can be learnt previous experience. This research explores the international interface of these issues illuminating elements inside the ‘black box’ of the largely unexplored dynamic of market mechanisms and UNFCCC negotiations. To do so, the research question was posed: What can be learnt from how market mechanisms are represented in the PA on climate change and what does this mean for their future? The research was largely conducted at the 21st Conference of the Parties (COP21) where negotiations culminated in the finalisation of the PA. To answer the research question, at COP21 qualitative data collection techniques were used to engage with NGOs, academics and negotiators. Six major findings emerged from this research. Complexity and a contested role for the UNFCCC characterised the representation of market mechanisms during the negotiation process (Findings 1 and 3). Political interests drove how market mechanisms were represented in the negotiation process (Finding 2) and a flexible PA architecture was necessary to facilitate accommodation of these interests (Finding 5). Despite pervasive complexity the international community demonstrated that it could learn lessons from previous experience (Finding 6). This was confirmed by international agreement on some desirable characteristics of market mechanisms, enshrined in the outcome of the PA (Finding 4). This research demonstrates that to maximise the potential of the PA outcome on market mechanisms beyond agreed principles and allowance for a variety of market-based approaches, further cooperation is required. High level principles enshrined in the PA outcome will need to be elucidated and refined before they are implemented, as will relationships between existing market mechanism instruments and Parties’ emissions reductions contributions under the PA. The PA outcome does not, and could not resolve all the challenges faced at the nexus of market mechanisms and the UNFCCC, and future negotiations are therefore likely to continue to be vexed by political, procedural and governance challenges.
Examining discussion of geoengineering in Australian news media
Creators: name: Burnard, Anna
Publisher: name: The Australian National University
Year: 2019

description: In the light of inadequate global emissions mitigation, geoengineering is increasingly being positioned by climate researchers and policymakers as a requirement for avoiding catastrophic levels of warming. However, the viability of geoengineering as a climate change strategy is contingent on how geoengineering is understood by the public, as it the public’s opinion of geoengineering that will guide research and political agendas. As news media is the primary way in which narratives surrounding geoengineering are created and circulated, the manner in which journalists discuss geoengineering will have a direct and substantial influence on public opinion, which in turn influences national policy. This thesis aims to do three things: (1) catalogue patterns in news media coverage of geoengineering in Australia, (2) identify the major media storylines and discourses surrounding geoengineering in Australian news media, and (3) understand the underlying ideologies that shape these patterns, storylines, and discourses.

Corona Virus and it's Impact on World Biodiversity

description: COVID-19 pandemic is influencing all parts of human society in the world. We all are concern first with how the pandemic will strafe our families, friends and people living around us. But we also have a duty to figure out how it will impact on world’s biodiversity. We all know that corona virus is a zoonotic disease but now it seems to be jumping back. On 6th April 2020 news emerged that a tiger named Nadia at Bronx Zoo, New York tested positive for the corona virus along with 6 other big cats, were infected by asymptomatic zoo-keeper. Tigers have been showing symptoms, including late March 2020. It was first time that a person infected the animal and got ailing. But US Centre for Disease Control and Prevention (CDC) has revolved that there is no evidence that animals and pets can spread COVID-19 to people or they are the carriers. But it is clear that animal can get infected by humans. Nevertheless, there are many positive scenarios came in front of us. Reduce human activities on account of lock down in India, has helped animals move freely in Western Ghats. COVID-19 lockdown has come as a blessing in disguise for flora & fauna in the Western Ghats. Forest officials have noticed large number of deer’s, elephants, bison’s and other animals walking on roads at Subramanya and surrounding areas because no one goes for hunting and other activities in the forest. Due to lockdown situation the environment become less polluted. As a result, many singing birds have come to common locality of India. An examination on diabetic patients revealed that while listening to birds chirping the amount of Insulin increases and glucose decreases in their blood. Birds tune also increases Beta-Endorphin hormone in our body, which helps us to reduce pain. Now days we are going through home arrest situation, it causes despondency in our life. Tune of few birds increase Dopamine chemical in our body it can decrease our despondency. At last, we can say it is too early to evaluate the overall impacts of the corona virus on biodiversity but some preliminary conclusions are possible. At this point protected areas appear to be safe and, in many places, biodiversity is benefiting from reduced human activities. However, this may not be true everywhere, only time will tell if this will have long term consequences.

description: The generalized models for higher-order logics introduced by Leon Henkin, and their multiple offspring over the years, have become a standard tool in many areas of logic. Even so, discussion has persisted about their technical status, and perhaps even their conceptual legitimacy. This paper gives a systematic view of generalized model techniques, discusses what they mean in mathematical and philosophical terms, and presents a few technical themes and results about their role in algebraic representation, calibrating provability, lowering complexity, understanding fixed-point logics, and achieving set-theoretic absoluteness. We also show how thinking about Henkin's approach to semantics of logical systems in this generality can yield new results, dispelling the impression of adhocness. This paper is dedicated to Leon Henkin, a deep logician who has changed the way we all work, while also being an always open, modest, and encouraging colleague and friend.

Enhanced intensities in valley at h {combining short stroke overlay}ω = 0.42 and 0.52 MeV are observed for the first time in the HF isotopes and are interpreted as due to band crossings which may involve i13 2,f 7 2 neutron and h 11 2 proton or higher orbital.

description: We discuss the particle size driven tunability of the coexistence of ferromagnetism and ferroelectricity in Pr0.67Ca0.33MnO3(PCMO) with the help of x ray diffraction, magnetization, impedance spectroscopy, and remanent polarization measurements. The remanent polarization measurements using the positive up negative down method clearly prove the existence of ferroelectricity in PCMO with phase separation between Zener polaron(ZP) ordered P21nm and disordered Pbnm structures. We also find that the ferroelectric response is enhanced in nanocrystalline samples so long as ZP ordering is not destroyed while the long-range antiferromagnetic ordering at low temperature in bulk system is replaced by ferromagnetic correlations in nanoparticles. The conclusion that by reducing the crystallite size it might be possible to make ferromagnetism and ferroelectricity coexist near room temperature should be generally applicable to all ZP ordered manganites.

description: We quantify the VDJ recombination and somatic hypermutation processes in human B-cells using probabilistic inference methods on high-throughput DNA sequence repertoires of human B-cell receptor heavy chains. Our analysis captures the statistical properties of the naive repertoire, first after its initial generation via VDJ recombination and then after selection for functionality. We also infer statistical properties of the somatic hypermutation machinery (exclusive of subsequent effects of selection). Our main results are the following: the B-cell repertoire is substantially more diverse than T-cell repertoires, due to longer junctional insertions; sequences that pass initial selection are distinguished by having a higher probability of being generated in a VDJ recombination event; somatic hypermutations have a non-uniform distribution along the V gene that is well explained by an independent site model for the sequence context around the hypermutation site.

Ludzie, kultura i społeczność Śląska w perspektywie kolonialnej, 2017. Książki na temat Górnego Śląska powstawały już w okresie dwudziestolecia międzywojennego, czego przykładem są dzieła Emila Szramka [1] czy Pawła Rybickiego [2]. W okresie Polski Ludowej dominującym paradygmatem badania regionów przede wszystkim tzw. Ziem Zachodnich i Północnych, w tym Śląska, był paradygmat integracji – to znaczy badanie polskości Górnego Śląska i integracji ludności rodzimej z ludnością przesiedloną z Kresów Wschodnich oraz napływową z centralnej Polski [3]. W zasadzie dopiero po 1989 roku badacze mieli możliwość podjęcia próby ukazania Górnego Śląska z perspektywy emics – jego mieszkańców i ich specyfiki.

description: The importance of access to greenspace has been widely acknowledged and its importance will continue to grow in to the future. Access to greenspace can provide a wide range of benefits from improving mental health to increasing social ties. In Canberra, Australia provision of greenspace has been a key feature in the development of the city and is now know as the ‘bush capital’. Given that greenspace is a core part of the city this study aims to identify if spatial behaviour patterns of residents differs in suburbs of different development eras. This exploratory study examined the effect of distance on frequency of use of greenspace in two areas of Canberra from different development eras and in relation to two household characteristics (dog ownership and children under the age of 15). A survey was distributed to residents in a sub-set of suburbs in the North Canberra and Gungahlin areas. Each survey contained a G-NAF number to allow for 100 percent geocoding of returned results. The survey had two sections. The first identified the demographic and household characteristic details whilst the second was related to greenspace usage. In the second section respondents were provided with a map and asked to mark greenspaces they had used in the last month and how frequently. Further questions in the section identified more information on residents greenspace usage. Euclidian distances from the respondent’s address to greenspace usage points were calculates and used in regression models to determine the effect of distance on frequency of use. In turn data from the regression models allowed for the development of hypothetical service area maps. The survey found that of the respondents 90 percent of them travelled to greenspace in the past month and most of them travelled there by foot. Respondents were typically going to greenspace to run or walk and are looking for wildlife and nature in greenspaces. One of key findings was that distance was found to have a statistically significant effect on the frequency of use of greenspace. For the overall sample with every additional kilometre to greenspace there was a 30.4 percent decrease in frequency of use. The analysis also found a difference in distance-decay between North Canberra and Gungahlin. The effect of distance on frequency of use was greater in Gungahlin. There was also a difference in distance decay between dog owners and non-dog owners as well as between households with children under the age of 15 and those without. The effect of distance on frequency of use was greater on dog owners than non-dog owners. For households with children under the age of 15 the effect of distance on frequency of use was less than households without. This information could be used in the future to better understand the spatial behaviour of residents interacting with greenspace and inform the development of new suburbs in the future to ensure that all residents are receiving maximum benefits from greenspace.

description: O kolei pisać można na wiele sposobów, a ten, w jaki czyni to Wojciech Tomasik, bydgoski historyk literatury i kulturoznawca, jest jednym z ciekawszych. Śledzenie nieoczywistych związków między kulturą a koleją służy temu, by coś ważnego powiedzieć nie tylko o pociągach, ale przede wszystkim o ludzkich doświadczeniach, wyobrażeniach, marzeniach i lękach. „Szalony bieg", najnowsza z „kolejowych" książek Tomasika to zbiór pięciu esejów „o europejskiej kulturze końca XIX wieku i polskim w niej udziale". I choć to niełatwe zadanie, to autorowi udaje się powiedzieć na ten temat coś odkrywczego.

description: Ultrafine (2-5 nm) particles of amorphous Ca-Mg co-doped ferrihydrite have been synthesized by surfactant mediated co-precipitation method. The evolution of the amorphous ferrihydrite by Ca-Mg co-doping is quite different from our earlier investigations on individual Ca and Mg doping studies. Amorphous phase of ferrihydrite for the present study has been confirmed by X-ray diffraction (XRD) and Mössbauer spectroscopy at room temperature and low temperatures (40 K and 20 K). Hematite nanoparticles with crystallite size about 8, 38 and 70 nm were obtained after annealing the as-prepared samples at 400, 600 and 800$^0$C respectively in air atmosphere. Superparamagnetism has been found in 8 nm sized hematite nanoparticles which has been confirmed from the magnetic hysteresis loop with zero remanent magnetization and coercive field and also from the superparamagnetic doublet of its room temperature Mössbauer spectrum. The magnetic properties of the 38 and 70 nm sized particles have been studied by room temperature magnetic hysteresis loop measurements and Mössbauer spectroscopy. The coercive field in these hematite nanoparticles increases with increasing particle size. Small amount of spinel MgFe$_{2}$O$_{4}$ phase has been detected in the 800$^0$C annealed sample.

description: „Gestern wird sein, was morgen gewesen ist." Mit diesem auf dem ersten Blick verwirrenden Satz fängt die Erzählung Das Treffen in Telgte von Günter Grass aus dem Jahr 1979 an. Die These, die hinter dieser Behauptung steckt, nämlich, dass Einstellungen zur Geschichte veränderbar sind, ist die Voraussetzung für das wachsende Interesse am Thema des hier zu besprechenden Buches. Es geht darin vor allem darum, wer, wie und zu welchen Zwecken Geschichtspolitik betreibt und dadurch die öffentliche Meinung beeinflussen will. Es versteht sich von selbst, dass die Ereignisse seit 1989 zu neuem Nachdenken über die Geschichte vor allem in Ost- und Mitteleuropa geführt haben.

Application of a Hidden Markov Model to remotely sensed snow cover measurements of a Himalayan basin
Creators: name: Chua, Sean Minhui Tashi
Publisher: name: The Australian National University

description: Remote sensing is used to monitor snow cover in areas without sufficient in-situ observations such as the Himalayas. However, commonly used remotely sensed snow cover products such as those provided by the Moderate Resolution Imaging Spectroradiometer (MODIS) have reduced accuracy in mountainous areas due to the negative influence of atmospheric effects and terrain in these regions. This thesis investigates the ability of a Hidden Markov model to limit erroneous misclassifications and reduce unrealistic estimates of snow cover. A Hidden Markov model is able to utilise a series of input observations, MODIS snow cover products in this case, and use these to calculate the probability of them representing the ground state. These probabilities can then be used to model the most likely series of states, this effectively provides a dynamic filter than can mitigate the problems faced when remotely sensing snow in mountainous areas. This approach was evaluated by applying a Hidden Markov model to MODIS snow cover measurements of a sub-basin in Eastern Nepal. The Hidden Markov model resulted in 16% and 9% increases in agreement with corresponding evaluation data than when compared to the two equivalent MODIS snow cover products that provided input data. The results also highlighted the ability of this approach to reduce data noise. Comparisons of snow covered area over time showed improved consistency in measurements when comparing the model output to both the daily and 8-day composite MODIS snow cover products. The ability of a Hidden Markov model to employ a dynamic filter that can utilise entire sequences of observations could offer improved accuracy when compared to other time-series filtering methods. This is because it is able to utilise a much a larger amount of observations without compounding losses in accuracy or resulting in reductions in temporal resolution. This study shows the potential for a HMM approach to provide a robust and flexible method for processing ‘noisy’ data such as remotely sensed snow cover measurements.

description: Absolute cross sections for a number of binary processes in the N14+Tb159 reaction have been determined by use of γ-particle coincidence techniques. The data are used to test a "sum-rule model" of complete- and incomplete-fusion reactions. The model assumes the reaction probabilities to be scaled by the available phase space and to be constrained additionally by the entrance-channel angular momentum limitations.

description: The characterization and applications of topological insulators depend critically on their protected surface states, which, however, can be obscured by the presence of trivial dangling bond states. Our first principle calculations show that this is the case for the pristine $(111)$ surface of SnTe. Yet, the predicted surface states unfold when the dangling bond states are passivated in proper chemisorption. We further extract the anisotropic Fermi velocities, penetration lengths and anisotropic spin textures of the unfolded $\barΓ$- and $\bar M$-surface states, which are consistent with the theory in http://dx.doi.org/10.1103/PhysRevB.86.081303 Phys. Rev. B 86, 081303 (R). More importantly, this chemisorption scheme provides an external control of the relative energies of different Dirac nodes, which is particularly desirable in multi-valley transport.
