description: Although empirical and theoretical studies affirm that punishment can elevate collaborative efforts, its emergence and stability remain elusive. By peer-punishment the sanctioning is something an individual elects to do depending on the strategies in its neighborhood. The consequences of unsustainable efforts are therefore local. By pool-punishment, on the other hand, where resources for sanctioning are committed in advance and at large, the notion of sustainability has greater significance. In a population with free-riders, punishers must be strong in numbers to keep the "punishment pool" from emptying. Failure to do so renders the concept of institutionalized sanctioning futile. We show that pool-punishment in structured populations is sustainable, but only if second-order free-riders are sanctioned as well, and to a such degree that they cannot prevail. A discontinuous phase transition leads to an outbreak of sustainability when punishers subvert second-order free-riders in the competition against defectors.

description: Catalyst-free vertically aligned graphene nanoflakes possessing a large amount of high density edge planes were functionalized using nitrogen species in a low energy N+ ion bombardment process to achieve pyridinic, cyanide and nitrogen substitution in hexagonal graphitic coordinated units. The evolution of the electronic structure of the functionalized graphene nanoflakes over the temperature range 20-800^{\circ}C was investigated in situ, using high resolution x-ray photoemission spectroscopy. We demonstrate that low energy irradiation is a useful tool for achieving nitrogen doping levels up to 9.6 at.%. Pyridinic configurations are found to be predominant at room temperature, while at 800^{\circ}C graphitic nitrogen configurations become the dominant ones. The findings have helped to provide an understanding of the thermal stability of nitrogen functionalities in graphene, and offer prospects for controllable tuning of nitrogen doping in device applications.

description: Introduction Spinal muscular atrophy (SMA) is a recessively inherited neuromuscular disorder resulting in muscle weaknesses. With no available cure, the impact of this condition can be manifold. The objective of this study is to understand the impact of living with SMA from the Persons with Spinal Muscular Atrophy (PWSMA) and their caregivers' perspectives. Methods Nationwide participants were recruited through SMA advocacy organization. Participants answered a validated questionnaire and DASS 21 tool, followed by an In-depth Interviews (IDI) or Focus Group Discussions (FGD). Consented participants were given a date for the researchers to meet up and performed the interview. The sessions were audio-taped, and the verbatim transcripts were analyzed thematically.   Results In the quantitative study, participants were reported to experience stress, anxiety, and depression. In the qualitative component, the impacts of living between the PWSMA and the caregivers include issues at the time of diagnosis, poor information delivery and the absence of supportive services. Participants' expressed their concerns living with self-doubt and turmoil with having to modify their lifestyles, familial relationships, and social lives. When exploring about future hope, themes emerged pointed towards having a united desire for better access to treatment, clinical trials, holistic care post diagnosis, and improved medical care services and disability access in public areas. Conclusion Our study highlighted a plethora of issues and challenges experienced by PWSMA and their caregivers in Malaysia. Sustained efforts from all stakeholders, PWSMA and their caregivers are required to bring about changes and thus lessen the burden of living with SMA patients in Malaysia.

description: Introduction Tuberculosis (TB) among children remains a significant public health problem in many parts of the world. This study aimed to determine the trends and predictors of TB treatment success among children in Malaysia. Methodology A cross-sectional study design using secondary data from MyTB version 2.1, a national TB surveillance database was conducted. R version 3.6.1 was utilized to perform the descriptive analysis and multivariable logistic regression model. Results The study analysed a total of 3550 registered TB cases among children from 2013 to 2017. Treatment success rate among children in Malaysia was 87.1% in 2013; however, the trend plateaued between 90.1 to 91.4% from 2014 until 2017. The predictors for TB treatment success were being Malaysian citizens, being the children without HIV co-infection, underwent treatment in public clinics or private facilities, chest X-ray grading of no lesion or minimal lesion. Children with BCG scars and being in older age group were also the positive predictors for TB treatment success. Children who were diagnosed with sputum-positive pulmonary TB or extrapulmonary TB were negatively associated with TB treatment success among children. The model can predict 73.39 % (AUC 95% CI: 70.15, 77.63) of the TB treatment outcome correctly according to the above predictors. Discussion/ Conclusion The trend of TB treatment success rate among children plateaued at 90%. This study concluded that treatment success was positively associated with children who were Malaysian citizens in the mild phase of TB disease.

description: An expected source of gravitational waves for future detectors in space are the inspirals of small compact objects into much more massive black holes. These sources have the potential to provide a wealth of information about astronomy and fundamental physics. On short timescales the orbit of the small object is approximately geodesic. Generic geodesics for a Kerr black hole spacetime have a complete set of integrals and can be characterized by three frequencies of the motion. Over the course of an inspiral, a typical system will pass through resonances where two of these frequencies become commensurate. The effect of the resonance will be to alter significantly the rate of inspiral for the duration of the resonance. Understanding the impact of these resonances on gravitational wave phasing is important to detect and exploit these signals for astrophysics and fundamental physics. Two differential equations that might describe the passage of an inspiral through such a resonance are investigated. These differ depending on whether it is the phase or the frequency components of a Fourier expansion of the motion that are taken to be continuous through the resonance. Asymptotic and hyperasymptotic analysis are used to find the late-time analytic behavior of the solution for a system that has passed through a resonance. Linearly growing (weak resonances) or linearly decaying (strong resonances) solutions are found depending on the strength of the resonance. In the weak-resonance case, frequency resonances leave an imprint (a resonant memory) on the gravitational frequency evolution. The transition between weak and strong resonances is characterized by a square-root singularity, and as one approaches this transition from above, the solutions to the frequency resonance equation bunch up into families exponentially fast.

description: The notion of weak truth-table reducibility plays an important role in recursion theory. In this paper, we introduce an elaboration of this notion, where a computable bound on the use function is explicitly specified. This elaboration enables us to deal with the notion of asymptotic behavior in a manner like in computational complexity theory, while staying in computability theory. We apply the elaboration to sets which appear in the statistical mechanical interpretation of algorithmic information theory. We demonstrate the power of the elaboration by revealing a critical phenomenon, i.e., a phase transition, in the statistical mechanical interpretation, which cannot be captured by the original notion of weak truth-table reducibility.

description: Das Zeichnen einer Skizze gilt als hilfreiche Strategie beim Lösen einer geometrischen Modellierungsaufgabe. Obwohl 13- bis 15-jährige Schüler*innen mit der Strategie der selbst erstellte Skizzen vertraut sind, wenden viele von ihnen die Zeichenstrategie nicht spontan an (Uesaka et al., 2007). Eine Möglichkeit, die Anwendung der Zeichenstrategie zu fördern, ist, die Schüler*innen aufzufordern, vor dem Lösen einer Aufgabe eine Skizze anzufertigen. In der aktuellen Studie untersuchen wir, wie sich Zeichenaufforderungen auf die Skizzennutzung durch Schüler*innen auswirken. Weitere Erklärungen dafür, warum Schüler*innen selten Skizzen nutzen, umfassen unter anderem defizitäres Strategiewissen und einen Mangel in strategiebezogener Motivation (Borkowski et al., 2000). Spezifisches Strategiewissen über selbst erstellte Skizzen (Skizzenwissen) beinhaltet das Wissen über die Merkmale einer qualitativ guten Skizze zu einer Modellierungsaufgabe. Vorangegangene Studien zeigten, dass Skizzenwissen eine wichtige Voraussetzung für das Zeichnen qualitativ guter Skizzen ist (Rellensmann, Schukajlow, Blomberg et al., 2021). Ob das Skizzenwissen eine Voraussetzung für die Nutzung der Zeichenstrategie ist, ist eine offene Frage. Strategiebezogene Motivation (SBM) ist Motivation, die sich aus den Merkmalen von Strategien und ihrer Anwendung ergibt und strategiebezogene Entscheidungen (z. B. die Anwendung einer Zeichenstrategie) erklären kann (Schukajlow et al., 2021). Eine offene Frage ist, inwiefern SBM (Selbstwirksamkeitserwartungen, Utility Value und wahrgenommene Kosten) die Nutzung von Skizzen durch Schüler*innen vorhersagt.

description: We analyse the dynamics of overlapping antiparallel treadmilling microtubules in the presence of crosslinking processive motor proteins that counterbalance an external force. We show that coupling the force-dependent velocity of motors and the kinetics of motor exchange with a bath in the presence of treadmilling leads generically to oscillatory behavior. In addition we show that coupling the polymerization kinetics to the external force through the kinetics of the crosslinking motors can stabilize the oscillatory instability into finite-amplitude nonlinear oscillations and may lead to other scenarios, including bistability.

description: Bibliography: p. 108-115.
description: Max Frisch's novel Homo faber appears at first glance to be a devastating critique of Walter Faber's technological world view and an affirmation of Hanna Piper's artistic or mythological standpoint. The work has usually been taken as Frisch's pro-Mythos contribution to the Mythos vs. Logos controversy. There are, however, no credible proponents of either viewpoint in the novel, nor is the handling of myth in the work any less ironic than that of technology. Homo faber is best understood primarily as a working-out of Frisch's concern with 11 Bi 1 dni sse, 11 or i nte 11 ectua 1 prejudices. Mythos and Logos are to be taken as examples of these prejudices. The thesis examines the treatment of both concepts, as well as the language of the novel in an attempt to demonstrate how such concepts appear to simplify the individual's dealings with life while actually standing in the way of a meaningful interaction with reality. Homo faber is not a discussion of the relative merits of Mythos and Logos, but rather a demonstration that the two only acquire genuine meaning when unified in a higher understanding which includes, but also transcends their separateness.

description: Given a Markovian Brownian martingale $Z$, we build a process $X$ which is a martingale in its own filtration and satisfies $X_1 = Z_1$. We call $X$ a dynamic bridge, because its terminal value $Z_1$ is not known in advance. We compute explicitly its semimartingale decomposition under both its own filtration $\cF^X$ and the filtration $\cF^{X,Z}$ jointly generated by $X$ and $Z$. Our construction is heavily based on parabolic PDE's and filtering techniques. As an application, we explicitly solve an equilibrium model with insider trading, that can be viewed as a non-Gaussian generalization of Back and Pedersen's \cite{BP}, where insider's additional information evolves over time.

Arboreal Galois representations and uniformization of polynomial dynamics

Subjects: subject: Number Theory (math.NT)
subject: FOS: Mathematics

description: Given a polynomial f of degree d defined over a complete local field, we construct a biholomorphic change of variables defined in a neighbourhood of infinity which transforms the action z->f(z) to the multiplicative action z->z^d. The relation between this construction and the Bottcher coordinate in complex polynomial dynamics is similar to the relation between the complex uniformization of elliptic curves, and Tate's p-adic uniformization. Specifically, this biholomorphism is Galois equivariant, reducing certain questions about the Galois theory of preimages by f to questions about multiplicative Kummer theory.

Hole densities up to $7.5\times10^{11}$ cm$^{-2}$ are obtained, and the peak hole mobility is about $10^4$ cm$^2$/Vs at 70 mK. The quantum Hall effect is observed. Shubnikov-de Haas oscillations show a beating pattern due to the spin-orbit effects, and the inferred zero-field spin splitting can be tuned by the gate voltage.

We consider the infinite horizon problem in a case which leads to a system of Hamilton-Jacobi equations. The numerical method is based on the Dynamic Programming Principle for every equation and on a global fixed point iteration. We present the numerical solutions of some two-player games in one and two dimensions. The paper has an experimental nature, but some features and properties of the approximation scheme are discussed.

description: We observe photocurrents induced in single layer graphene samples by illumination of the graphene edges with circularly polarized terahertz radiation at normal incidence. The photocurrent flows along the sample edges and forms a vortex. Its winding direction reverses by switching the light helicity from left- to right-handed. We demonstrate that the photocurrent stems from the sample edges, which reduce the spatial symmetry and result in an asymmetric scattering of carriers driven by the radiation electric field. The developed theory is in a good agreement with the experiment. We show that the edge photocurrents can be applied for determination of the conductivity type and the momentum scattering time of the charge carriers in the graphene edge vicinity.

Nutrient impacts on coral reefs captured through macroalgal isotopes
Creators: name: Vaughan, Ellie
Publisher: name: Lancaster University
Year: 2021

description: Anthropogenic nutrient runoff is a major local stressor on coral reefs but compared to research on global climate change and overfishing, progress has been slower at quantifying its effects, particularly at the ecosystem scale. This is due to the difficulties in cost-effectively capturing the high spatio-temporal variability of bioavailable nutrients in reef systems. In this thesis, I examine common bioindicators and associated methodologies for assessing nutrient regimes as well as the relationships between nutrient and biological responses of the bioindicators. I first compare the precision and cost-effectiveness of five nutrient signatures (δ15N, δ13C, %N, %C and C:N Ratio) in a suite of eight indicators across 21 reefs around the inner Seychelles islands. I show that the congruency between the three most precise types (brown macroalgae, green macroalgae and zoanthids) was low, which was likely due to differences in species-specific ecological strategies (e.g. nutrient uptake and/ or storage capacity). I then test the theory that species within the same functional groups should respond similarly to nutrient enrichment using a) passive biomonitoring (sampling along a nutrient gradient) b) active biomonitoring (in situ reciprocal transplant experiment), and c) manipulative laboratory experiments (nutrient supply rates). Overall, these studies suggest that even the responses of morphologically-similar macroalgae with different strategies for nutrient uptake can vary over fine spatio-temporal scales, particularly if they are not nutrient-limited. Finally, I use one of these methodologies in a real-world scenario to investigate the influence of mass coral mortality events on δ15N signatures of transplanted macroalgae 1) before and after the 2016 bleaching event in the Seychelles, and 2) during the 2019 bleaching event in Mo’orea. Both case studies strongly imply that macroalgae can potentially take up this mass release of dead coral tissue, and possibly locking them into local biogeochemical cycles for up to a year after a bleaching event. I conclude that a traits-based approach, using a suite of congruent bioindicators with the same functional traits (i.e. rapid nutrient uptake), would be most cost-effective for future research and monitoring programs.

title: Secondary teacher and teacher educator perspectives on ‘demonstration’ as a signature pedagogy for Design and Technology: Implications for initial teacher education
Creators: name: McLain, M
Publisher: name: Liverpool John Moores University
Year: 2022

description: This research consists of eight peer-reviewed journal articles and contributes to the under-theorised pedagogy of demonstration in design and technology (D&T). Demonstration is presented as a signature pedagogy, commonly used for teaching practical skills (or procedural knowledge). The aims of the studies represented in this research include exploring secondary teacher and teacher educator views, addressing the apparent lack of evidence and systematic research into D&T pedagogy and practice. The literature suggests that diverse theoretical perspectives are associated with teachers’ views on modelling and explaining in D&T, including constructivism, social learning, and cognitive load; with the expert teacher adopting a more directive and restrictive approach during demonstration. The overarching research questions were concerned with pre- and in-service teacher and teacher educator views on effective approaches to demonstration and the use of a signature pedagogies framework to evaluate and select appropriate teaching methods. A variety of research methods were used in the studies, including autoethnography and mixed-methods questionnaires, with the particular use of Q Methodology to explore the subjective views of participants regarding effective demonstration. The sampling was non-probability, and research participants represented in the portfolio of articles included 202 Key Stage 3 pupils from five secondary schools in North West England, seven teachers and 11 teacher educators from across England and Scotland, and 192 preservice teachers in Merseyside. The findings indicate that demonstration was considered a teacher-led and relatively restrictive form of modelling, with participants ranking more expansive strategies lower in importance, including those that promote the consolidation of learning and facilitation of autonomy. Later studies revealed two pedagogical archetypes for D&T and Science, Technology, Engineering and Mathematics (STEM) educators: the first, a more behaviourist teacher-as-expert approach and the second a more constructivist teacher-as-facilitator led approach. However, these two perspectives were not expressed as mutually exclusive, the differences being subtle and nuanced. This research suggests that teachers should consider demonstration as a surface structure (teaching method) on an expansive-restrictive pedagogical continuum, with an understanding of its benefits and limitations, as part of a broad pedagogical repertoire. Further research is needed on the impact of various approaches to demonstration in D&T, including frontloading, just-in-time, and after-failure approaches, and the impacts they have on students’ capability and learning.

Canonical heights for Henon maps

description: We consider the arithmetic of Henon maps f(x, y)=(ay, x+f(y)) defined over number fields and function fields, usually with the restriction that a=1. We prove a result on the variation of Kawaguchi's canonical height in families of Henon maps, and derive from this a specialization theorem, showing that the set of parameters above which a given non-periodic point becomes periodic is a set of bounded height. Proving this involves showing that the only points of canonical height zero for a Henon map over a function field are those which are periodic (in the non-isotrivial case). In the case of quadratic Henon maps f(x, y)=(y, x+y^2+b), we obtain a stronger result, bounding the canonical height below by a quantity which grows linearly in the height of b, once the number of places of bad reduction is fixed. Finally, we propose a conjecture regarding rational periodic points for quadratic Henon maps defined over the rational numbers, namely that they can only have period 1, 2, 3, 4, 6, or 8. We check this conjecture for the first million values of the parameter b, ordered by height.

description: We study the accuracy of Bayesian supervised method used to cluster individuals into genetically homogeneous groups on the basis of dominant or codominant molecular markers. We provide a formula relating an error criterion the number of loci used and the number of clusters. This formula is exact and holds for arbitrary number of clusters and markers. Our work suggests that dominant markers studies can achieve an accuracy similar to that of codominant markers studies if the number of markers used in the former is about 1.7 times larger than in the latter.

description: Microplastic pollution in soils is an emerging topic in the scientific community, with researchers striving to determine the occurrence and the impact of microplastics on the soil's health, ecology and functionality. However, information on the microplastic contamination of soils is limited, due to a lack of suitable analytical methods. As micro-Fourier-transform infrared spectroscopy (µ-FTIR), next to Raman spectroscopy, is one of the few methods that allow the determination of the number, polymer type, shape and size of microplastic particles, this study addresses the challenge of purifying soil samples sufficiently to allow a subsequent µ-FTIR analysis. A combination of freeze-drying, sieving, density separation and a sequential enzymatic-oxidative digestion protocol enables the removal of the mineral mass (>99.9% DW) and an average reduction of 77% DW of the remaining organic fraction. Additional to visual integrity, attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), gel permeation chromatography (GPC) and differential scanning calorimetry (DSC) showed that polyamide, polyethylene, polyethylene terephthalate and polyvinyl chloride in the size range of 100-400µm were not affected by the approach. However, the biodegradable polylactic acid showed visible signs of degradation and reduced molecular weight distribution after the protease treatment. Nevertheless, the presented purification protocol is a reliable and robust method to purify relatively large soil samples of around 250 g DW for spectroscopic analysis in microplastic research, and has been shown to recover various microplastic fibers and fragments down to a size of 10 µm from natural soil samples.

description: We study a class of quantum two-dimensional models with complex potentials of specific form. They can be considered as the generalization of a recently studied model with quadratic interaction not amenable to conventional separation of variables. In the present case, the property of shape invariance provides the equidistant form of the spectrum and the algorithm to construct eigenfunctions analytically. It is shown that the Hamiltonian is non-diagonalizable, and the resolution of identity must include also the corresponding associated functions. In the specific case of anharmonic second-plus-fourth order interaction, expressions for the wave functions and associated functions are constructed explicitly for the lowest levels, and the recursive algorithm to produce higher level wave functions is given.

title: A high-protein Mediterranean-style diet and resistance exercise for cardiac rehabilitation
Creators: name: Kirwan, R
Publisher: name: Liverpool John Moores University

description: Cardiovascular disease (CVD) is the number one cause of death globally. Cardiac rehabilitation (CR) is an essential component of long-term recovery following a cardiac event. Typical CR may not be optimal for patients presenting with sarcopenic obesity (SO) who present with reduced muscle mass and elevated adipose tissue, and may indicate greater cardiovascular disease risk. Resistance exercise and high-protein diets are known to increase muscle mass, while Mediterranean-style diets have been shown to reduce CVD risk. A high-protein Mediterranean-style diet combined with resistance exercise intervention is yet to be trialled in cardiac rehabilitation populations. As such, this thesis, provides rationale for the development of such a protocol using multiple research methods including literature review, systematic review and meta-analysis, Mendelian randomization and qualitative analysis. A wide variety of topics are discussed including: the importance of muscle in the development of chronic disease; the effects of protein and resistance exercise on muscle mass in older adults; the effects of lifetime vitamin D levels on muscle mass; the effect of lean mass on lipoprotein particle size; the impact of COVID-19 on CR practice; the protoocl development for a diet and exercise intervention in CR; and investigating the feasibility of said protocol. As such, this thesis provides a comprehensive rationale for and methodology to achieve a high-protein Mediterranean-style diet and RE intervention in a CR population.

description: We design a plasmonic fiber waveguide (PFW) composed of coaxial cylindrical metal-dielectric multilayers in nanoscale, and constitute the corresponding dynamical equations describing the modes of propagation in the PFW with the Kerr nonlinearity in the dielectric layers. The physics is connected to the discrete matrix nonlinear Schrödinger equations, from which the highly confined ring-like solitons in scale of subwavelength are found both for the visible light and the near-infrared light in the self-defocusing condition. Moreover, the confinement could be further improved when increasing the intensity of the input light due to the cylindrical symmetry of the PFW, which means both the width and the radius of the ring are reduced.

description: Magneto-electric multiferroics exemplified by TbMnO3 possess both magnetic and ferroelectric long-range order. The magnetic order is mostly understood, whereas the nature of the ferroelectricity has remained more elusive. Competing models proposed to explain the ferroelectricity are associated respectively with charge transfer and ionic displacements. Exploiting the magneto-electric coupling, we use an electric field to produce a single magnetic domain state, and a magnetic field to induce ionic displacements. Under these conditions, interference charge-magnetic X-ray scattering arises, encoding the amplitude and phase of the displacements. When combined with a theoretical analysis, our data allow us to resolve the ionic displacements at the femtoscale, and show that such displacements make a significant contribution to the zero-field ferroelectric moment.

description: We consider a monotone increasing operator in an ordered Banach space having $u_-$ and $u_+$ as a strong super- and subsolution, respectively. In contrast with the well studied case $u_+ < u_-$, we suppose that $u_- < u_+$. Under the assumption that the order cone is normal and minihedral, we prove the existence of a fixed point located in the ordered interval $[u_-,u_+].$

title: Contributions to Service Level Agreement (SLA), Negotiation and Monitoring in Cloud Computing

description: Cloud computing is a dynamic field of research, as the latest advances in the cloud computing applications have led to development of a plethora of cloud services in the areas of software, hardware, storage, internet of things connected to the cloud, and 5G supported by the cloud networks. Due to ever increasing developments and the subsequent emergence of a wide range of cloud services, a cloud market was created with cloud providers and customers seeking to buy the cloud services. With the expansion of the cloud market and the presence of a virtual environment in which cloud services are provided and managed, the face to-face meetings between customers and cloud providers is almost impossible, and the negotiation over the cloud services using the state-of-the-art autonomous negotiation agents has been theorized and researched by several researchers in the field of cloud computing, however, the solutions offered by literature are less applicable in the real-time cloud market with the evolving nature of services and customers’ requirements. Therefore, this study aimed to develop the solutions addressing issues in relation to negotiation of cloud services leading to the development of a service-level agreement (SLA), and monitoring of the terms and conditions specified in the SLA. We proposed the autonomous service-level framework supported by the autonomous agents for negotiating over the cloud services on behalf of the cloud providers and customers. The proposed framework contained gathering, filtering, negotiation and SLA monitoring functions, which enhanced its applicability in the real-time cloud market environment. Gathering and filtering stages facilitated the effectiveness of the negotiation phase based on the requirements of customers and cloud services available in the cloud market. The negotiation phase was executed by the selection of autonomous agents, leading to the creation of an SLA with metrics agreed upon between the cloud provider and the customer. Autonomous agents improved the efficiency of negotiation over multiple issues by creating the SLA within a short time and benefiting both parties involved in the negation phase. Rubinstein’s Alternating Offers Protocol was found to be effective in drafting the automated SLA solutions in the challenging environment of the cloud market. We also aimed to apply various autonomous agents to build the new algorithms which can be used to create novel negotiation strategies for addressing the issues in SLAs in cloud computing. The monitoring approach based on the CloudSim tool was found to be an effective strategy for detecting violations against the SLA, which can be an important contribution to building effective monitoring solutions for improving the quality of services in the cloud market.

description: GRB 070125 is among the most energetic bursts detected and the most extensively observed so far. Nevertheless, unresolved issues are still open in the literature on the physics of the afterglow and on the GRB environment. In particular, GRB 070125 was claimed to have exploded in a galactic halo environment, based on the uniqueness of the optical spectrum and the non-detection of an underlying host galaxy. In this work we collect all publicly available data and address these issues by modelling the NIR-to-X-ray spectral energy distribution (SED) and studying the high signal-to-noise VLT/FORS afterglow spectrum in comparison with a larger sample of GRB absorbers. The SED reveals a synchrotron cooling break in the UV, low equivalent hydrogen column density and little reddening caused by a LMC- or SMC-type extinction curve. From the weak MgII absorption at z=1.5477 in the spectrum, we derived logN(MgII)=12.96+0.13-0.18 and upper limits on the ionic column density of several metals. These suggest that the GRB absorber is most likely an LLS with a 0.03Z\odot
