description: This study investigates landowners’ preferences for afforestation contracts in Denmark using a choice experiment. Four attributes are investigated: purpose of afforestation, option of denouncing the contract, control by authorities and subsidy levels. One average, landowners showed strong preferences for having the option to denounce the contracts whereas increasing control lead to increases in required compensation. Biodiversity was the most popular purpose.

description: The first part of the paper reproduces the text that was intended to be published in a Lithuanian professional forestry journal. It first concisely reviews State forestry administrations in the countries of the Baltic Sea region, judging their adherence to the traditional model of bureaucracy versus the model of new public administration. Then it describes the Lithuanian approach in greater detail, providing criticism of inefficiencies caused by an overly bureaucratic administration. Attempts to publish the text led to the closure of the journal. Reflecting on this media turmoil, the second part of the paper discusses the role of a forest scientist. Should s/he be a neutral expert expedient to existing institutional structures, or rather seek to catalyze the desired policy processes? Is it worth to engage in “popular discourses” or better to stick solely to the standard production of peer review articles?

Subjects: subject: FOS: Engineering and technology

description: Simplicial nim games, a class of impartial games, have very interesting mathematical properties. Winning strategies on a simplicial nim game can be determined by the set of positions in the game whose Sprague-Grundy values are zero (also zero positions). In this work, I provide two major contributions to the study of simplicial nim games. First, I provide a modern and efficient implementation of the Sprague-Grundy function for an arbitrary simplicial complex, and discuss its performance and scope of viability. Secondly, I provide a method to find a simple mathematical expression to model that function if it exists. I show the effectiveness of this method on determining mathematical expressions that classify the set of zero positions on
several simplicial nim games.

description: Nucleon spin structure functions have been investigated mainly by longitudinally-polarized ones for finding the origin of the nucleon spin. Other types of spin structure functions are transversely-polarized ones. In particular, quark transversity distributions in the nucleons have very different properties from the longitudinally-polarized quark distribution functions, especially in scaling violation, because they are decoupled from the gluon transversity, due to the fact that they are helicity-flip (chiral-odd) distributions. Such studies are valuable for finding not only the origin of the nucleon spin but also a signature on physics beyond the standard model, because the electric dipole moment of the neutron is proportional to the transversity distributions. Now, there is experimental progress on the quark transversity distributions; however, there is no experimental information on gluon transversity. In fact, the gluon transversity does not exist for the spin-1/2 nucleon due to the helicity-conservation constraint. One needs a hadron with spin more than or equal to one, so that the helicity flip of two units is allowed. A stable spin-1 target is, for example, the deuteron for studying the gluon transversity. In this work, we propose a possibility for finding the gluon transversity at hadron-accelerator facilities, especially in the proton-deuteron Drell-Yan process with the linearly-polarized deuteron, by showing theoretical formalism and numerical results. We show the dependencies of the Drell-Yan cross section on the dimuon-mass squared $M_{μμ}^{\,2}$, the dimuon transverse-momentum $q_T$, the dimuon rapidity $y$ in the center-of-momentum frame, and the magnitude of the gluon transversity $Δ_T g$.

description: Jennifer Clack (née Agnew) dedicated her entire research career of more than 40 years to the fish-tetrapod transition, the evolutionary process during the Devonian and Carboniferous periods that transformed a lineage of lobe-finned fishes into the earliest land vertebrates. She was widely regarded as the world leader in this field. During an expedition in the summer of 1987 to the Late Devonian vertebrate localities of East Greenland, Clack collected numerous fossils of two of the earliest tetrapods, Acanthostega and Ichthyostega, which revolutionized the understanding of these animals and created a surge of renewed interest in what had previously been a small and somnolent research area. However, much of her work focused on the Carboniferous, the time when the group underwent its first major diversification and the amphibian and amniote lineages first appeared. Here too she produced a stream of ground-breaking discoveries. She published close to 100 primary research papers, many in flagship journals, as well as numerous popular articles and the influential textbook Gaining Ground. Modest and unassuming in person, and unfailingly supportive towards young scientists, Jennifer Clack was enormously respected and helped to make the entire research field into a more open, collaborative, and welcoming environment.
Systematic study on production of hidden-bottom pentaquark via $γp$ and $π^{-}p$ scatterings

description: The production of hidden-bottom pentaquark $P_{b}$ states via $γp$ and $π^{-}p$ scatterings is studied within an effective Lagrangian approach and the vector-meson-dominance mechnism. For the $P_{b}$ production in the process $γp\rightarrow Υp$, the dipole Pomeron model is employed to calculate the background contribution, and the experimental data can be well described. For the process $π^{-}p\rightarrow Υn$, the Reggeized $t$-channel with $π$ exchange is considered as the main background for the $P_{b}$ production. Near the threshold, two-peak structure from the states $P_{b (11080)$ and $P_{b}(11125)$ can be observed if energy bin width is chosen as 0.01 GeV, and the same result is obtained in the $π^{-}p$ scattering. Moreover, by taking the branching ratio of Br$[{P_{b}\rightarrow πN}]\simeq 0.05\%$, the numerical result shows that the average value of cross section from the $P_{b}(11080)$ state produced in the $γp$ or $π^{-}p$ scattering reaches at least 0.1 nb with a bin of 0.1 GeV. Even if we reduce the branching ratio of the $P_{b}$ state into $πN$ channel by one order, the theoretical average of the cross section from $P_{b}(11080)$ production in $π^{-}p$ scattering can reach the order of 0.01 nb with a bin of 0.1 GeV, which means that the signal can still be clearly distinguished from the background. The experimental measurements and studies on the hidden-bottom pentaquark $P_{b}$ state production in the $γp $ or $π^{-}p$ scattering near-threshold energy region around $W\simeq 11$ GeV are strongly suggested, which are accessible at COMPASS and JPARC. Particularly, the result of the photoproduction suggests that it is very promising to observe the hidden-bottom pentaquark at proposed EicC facility in China.

description: Serratia sp. ATCC39006 (S39006) is a rod-shaped, motile, Gram-negative phytopathogenic bacterium. It is the only enterobacterium known to make gas vesicles (GVs) naturally. GVs are proteinaceous, intracellular organelles used by bacteria to enable upward flotation in aquatic environments. S39006 also produces various secondary metabolites, including the tripyrrole red-pigmented antibiotic, 2‐methyl‐3‐pentyl‐6‐methoxyprodigiosin (prodigiosin; a prodiginine) and the β-lactam antibiotic, 1-carbapen-2-em-3-carboxylic acid (a carbapenem). The production and regulation of GV assembly is a complex process, which is part of a wider regulatory network affecting various phenotypes, including the carbapenem and prodigiosin antibiotics. The present study aimed to identify genes involved in pleiotropic co-regulation of GV production and biosynthesis of the carbapenem and prodigiosin antibiotics. To identify new regulatory genes, random transposon mutagenesis was employed. Mutants defective in the ribose operon repressor (rbsR), topoisomerase I (topA) and the preQ0 transporter (orf9) were identified from a comprehensive mutant library. The rsbR mutant was defective in GV, carbapenem and prodigiosin production, but showed increased swimming and swarming motility. Additionally, a siderophore, cellulase and plant virulence were reduced in the mutant. In the topA mutant, prodigiosin was greatly elevated but reduction was observed in carbapenem, cellulase, pectate lyase, N-BHL and siderophore production, and motility. The orf9 gene also had multiple physiological effects in S39006. Reduced GV, prodigiosin and cellulase production, but increased swimming and swarming motilities, were observed in the orf9 mutant. To understand the role of RbsR as a global regulator in S39006, comparative quantitative proteomic analysis was employed. Proteins involved in GV biogenesis, motility, antibiotic and cellulase production, as well as five previously identified transcriptional regulators, were affected in the mutant. With molecular genetic characterisation and proteomic analysis, this study identified three regulatory genes, rsbR, topA, and orf9 that are not only important in modulating GV morphogenesis (and flotation) but are also pleiotropic for control of biosynthesis of the secondary metabolites, some secreted enzymes and motility.

description: In this thesis we study new anisotropic variational regularisers and partial differential equations (PDEs) for solving inverse imaging problems that arise in a variety of real-world applications. Firstly, we introduce a new anisotropic higher-order total directional variation regulariser. We describe both the theoretical and the numerical details for its use within a variational formulation for solving inverse problems and give examples for the reconstruction of noisy images and videos, image zooming and the interpolation of scattered surface data. Secondly, we focus on a non-symmetric drift-diffusion equation, called osmosis. We propose an efficient numerical implementation of the osmosis equation, based on alternate directions and operator splitting techniques. We study their scale-space properties and show their efficiency in processing large images. Moreover, we generalise the osmosis equation to accommodate suitable directional information: this modification turns out to be useful to correct for the well-known blurring artefacts the original osmosis model introduces when applied to shadow removal in images. Last but not least, we explore applications of variational models and PDEs to cultural heritage conservation. We develop a new non-invasive technique that uses multi-modal imaging for detecting sub-superficial defects in fresco walls at sub-millimetre precision. We correct light-inhomogeneities in these imaging measurements that are due to measurement errors via osmosis filtering, in particular making use of the efficient computational schemes that we introduced before for dealing with the large-scale nature of these measurements. Finally, we propose a semi-supervised workflow for the detection and inpainting of defects in damaged illuminated manuscripts.

description: We study the correlation between CP violation in neutrino oscillations and leptogenesis in the framework with two heavy Majorana neutrinos and three light neutrinos. Among three unremovable CP phases, a heavy Majorana phase contributes to leptogenesis. We show how the heavy Majorana phase contributes to Jarlskog determinant $J$ as well as neutrinoless double $β$ decay by identifying a low energy CP violating phase which signals the CP violating phase for leptogenesis. For some specific cases of the Dirac mass term of neutrinos, a direct relation between lepton number asymmetry and $J$ is obtained. For the most general case of the framework, we study the effect on $ J $ coming from the phases which are not related to leptogenesis, and also show how the correlation can be lost in the presence of those phases.

description: For every associative algebra $A$ and every class $\mathcal{C}$ of representations of $A$ the following question (related to nullstellensatz) makes sense: Characterize all tuples of elements $a_1,\ldots,a_n \in A$ such that vectors $π(a_1)v,\ldots,π(a_n)v$ are linearly dependent for every $π\in \mathcal{C}$ and every $v$ from the representation space of $π$. We answer this question in the following cases: (1) $A=U(L)$ is the enveloping algebra of a finite-dimensional complex Lie algebra $L$ and $\mathbb{C}$ is the class of all finite-dimensional representations of $A$. (2) $A=U(\mathfrak{sl}_2(\mathbb{C}))$ and $\mathbb{C}$ is the class of all finite-dimensional irreducible representations of $A$. (3) $A=U(\mathfrak{sl}_3(\mathbb{C}))$ and $\mathbb{C}$ is the class of all finite-dimensional irreducible representations of $A$ with sufficiently high weights. In case (1) the answer is: tuples that are linearly dependent over $\mathbb{C}$ while in cases (2) and (3) the answer is: tuples that are linearly dependent over the center of $A$. Similar results have been proved before for free algebras and Weyl algebras.

description: Photoacoustic tomography (PAT) is a nonionizing imaging modality capable of acquiring high contrast and resolution images of optical absorption at depths greater than traditional optical imaging techniques. Practical considerations with instrumentation and geometry limit the number of available acoustic sensors and their view of the imaging target, which result in significant image reconstruction artifacts degrading image quality. Iterative reconstruction methods can be used to reduce artifacts but are computationally expensive. In this work, we propose a novel deep learning approach termed pixelwise deep learning (PixelDL) that first employs pixelwise interpolation governed by the physics of photoacoustic wave propagation and then uses a convolution neural network to directly reconstruct an image. Simulated photoacoustic data from synthetic vasculature phantom and mouse-brain vasculature were used for training and testing, respectively. Results demonstrated that PixelDL achieved comparable performance to iterative methods and outperformed other CNN-based approaches for correcting artifacts. PixelDL is a computationally efficient approach that enables for realtime PAT rendering and for improved image quality, quantification, and interpretation.

description: This dissertation consists of three chapters on semi-parametric Bayesian Econometric methods. Chapter 1 applies a semi-parametric method to demand systems, and compares the abilities to recover the true elasticities of different approaches to linearly estimating the widely used Almost Ideal demand model, by either iteration or approximation. Chapter 2 co-authored with Dr. Melvyn Weeks introduces a new semi-parametric Bayesian Generalized Least Square estimator, which employs the Dirichlet Process prior to cope with potential heterogeneity in the error distributions. Two methods are discussed as special cases of the GLS estimator, the Seemingly Unrelated Regression for equation systems, and the Random Effects Model for panel data, which can be applied to many fields such as the demand analysis in Chapter 1. Chapter 3 focuses on the subset selection for the efficiencies of firms, which addresses the influence of heterogeneity in the distributions of efficiencies on subset selections by applying the semi-parametric Bayesian Random Effects Model introduced in Chapter 2.

description: We study band-dominated operators on (subspaces of) $L_p$-spaces over metric measure spaces of bounded geometry satisfying an additional property. We single out core assumptions to obtain, in an abstract setting, definitions of limit operators, characterizations of compactness and Fredholmness using limit operators; and thus also spectral consequences. In this way, we recover and unify the classical and recent results on limit operator techniques, but also gain new insights and are able to treat further applications.

description: We present high spatial resolution X-ray Chandra HRC and HST WFPC2 Halpha observations of the prototypical infrared luminous galaxy NGC6240. The central region of this system shows a remarkably complex morphology, with filaments and loops observed in the optical and X-rays. The total X-ray luminosity is dominated by the extended emission. Both nuclei are clearly detected in the HRC image and both appear to be extended. The energetics of the nuclei imply that the southern nucleus is the more plausible counterpart to the obscured AGN. The overall SED of the galaxy is in good agreement with a blend of starburst and AGN components which have similar bolometric luminosities, L_bol ~ 5e45 ergs/s, with the starburst dominating the observed continuum in the near-IR (K-band), optical and soft X-ray bands.

description: In this work we have collected observational data for 1315 PSRs. Distances and others parameters for these PSRs were estimated. We present improved distance estimates for radio pulsars by considering importance of their physical properties and improvement of distribution of SFRs (star formation regions) in the Galaxy. For this purpose, both a list of accurate calibrators was constructed and several accurate criteria were established. The following values were calculated from PSRs observational data: luminosities at 400 Mhz and 1400 Mhz, characteristic times, strength of magnetic field and rate of rotation energy. This compilation of data is mainly necessary for statistical investigations and for the physical properties of neutron stars. The whole data is prepared in a publicly accessible web page: http://www.xrbc.org/pulsar/ .

description: Transrectal prostate biopsy (TRbx) transfers colonic bacteria into prostatic tissue, potentially causing infectious complications, including sepsis. Our objective was to determine whether biopsy needle shape, surface properties and sampling mechanism affect the number of bacteria transferred through the colon wall, and evaluate a novel needle with improved properties. The standard Tru-Cut biopsy needle used today was evaluated for mechanisms of bacterial transfer in a pilot study. A novel Tru-Cut needle (Forsvall needle prototype) was developed. TRbx was simulated using human colons ex-vivo. Four subtypes of the prototype needle were compared with a standard Tru-Cut needle (BARD 18 G). Prototype and standard needles were used to puncture 4 different colon specimens in 10 randomized sites per colon. Needles were submerged into culture media to capture translocated bacteria. The media was cultured on blood agar and then the total amount of transferred bacteria was calculated for each needle. The primary outcome measure was the percent reduction of bacteria translocated by the prototype needles relative to the standard needle. Secondary outcome measures were the effects of tip design and coating on the percent reduction of translocated bacteria. Prototype needles reduced the number of translocated bacteria by, on average, 96.0% (95% confidence interval 93.0-97.7%; p The Forsvall needle significantly reduces colonic bacterial translocation, suggesting that it could reduce infectious complications in prostate biopsy. A clinical trial has been initiated.

description: Nos questions de recherches portent sur l’identification des principales difficultés mathématiques que l’on trouve dans un problème de physique, sur une analyse de ces difficultés, sur les solutions possibles pour les surmonter, ainsi que sur les origines didactiques de celles-ci. Nous présentons donc en premier lieu un exercice de physique sur le plan incliné, problème typique que l’on peut rencontrer dans les supports de cours de physique, en soulevant les difficultés mathématiques qui interviennent. Nous avons ensuite regroupé ces difficultés en quatre difficultés principales : déterminer l’angle d’inclinaison du plan en identifiant les triangles semblables, déterminer les composantes de la force de pesanteur à l’aide des fonctions trigonométriques, utiliser le concept de vecteur et, enfin, résoudre des équations. Nous avons analysé ces difficultés en apportant des pistes de solutions pour les surmonter, notamment à l’aide de la théorie sur les transferts de connaissances d’une branche à une autre et celle de la variation de Marton, puis nous avons cherché les éventuelles causes de ces difficultés au delà de la matière qui est enseignée, à savoir dans les interactions entre les deux disciplines au niveau des enseignants, et dans l’inter-didactique des mathématiques et de la physique qui, elle, soulève des difficultés propres aux conversion d’une représentation dans une discipline à une représentation dans l’autre discipline.

 Notes. It was indicated by Chandler (2004a) that the type specimen of Zygomyia simplex (in NMBA) had been examined and found to be conspecific with Z. valida; this specimen was a male rather than a female as stated in the original description. As this has only been reported on line, this synonymy is formally established here.

Nonperturbative tuning of $O(a^2)$ improved staggered fermions

description: We perform a nonperturbative tuning of the coefficients in the $O(a^2)$ improved action for staggered fermions. The mass splitting for the pions of different doubler flavor is used as a measure of the symmetry breaking effects introduced by $O(a^2)$ discretization errors. We find that the flavor nondegeneracy can be somewhat reduced but not eliminated by such a tuning, indicating the need for new terms in the action to reduce the nondegeneracy.

description: Context. As the 4th most abundant element in the universe, carbon (C) is widespread in the interstellar medium (ISM) in various allotropic forms (e.g., fullerenes have been identified unambiguously in many astronomical environments, the presence of polycyclic aromatic hydrocarbon molecules in space has been commonly admitted, and presolar graphite as well as nanodiamonds have been identified in meteorites). As stable allotropes of these species, whether carbon nanotubes (CNTs) and their hydrogenated counterparts are also present in the ISM or not is unknown. Aims. We explore the possible routes for the formation of CNTs in the ISM and calculate their fingerprint vibrational spectral features in the infrared (IR). Methods. We study the hydrogen-abstraction/acetylene-addition (HACA) mechanism and investigate the synthesis of nanotubes using density functional theory (DFT). The IR vibrational spectra of CNTs and hydrogenated nanotubes (HNTs), as well as their cations, have also been obtained with DFT. Results. We find that CNTs could be synthesized in space through a feasible formation pathway. CNTs and cationic CNTs, as well as their hydrogenated counterparts, exhibit intense vibrational transitions in the IR. Their possible presence in the ISM could be investigated by comparing the calculated vibrational spectra with astronomical observations made by the Infrared Space Observatory, Spitzer Space Telescope, and particularly the upcoming James Webb Space Telescope.

description: Topography of silicon surfaces irradiated by a 2 MeV Si$^+$ ion beam at normal incidence and ion fluences in the range $10^{15}-10^{16}$ ions/cm$^{2}$ has been investigated using scanning tunneling microscopy. At length scales below $\sim$~50 nm, surface smoothing is observed; the smoothing is more prominent at smaller length scales. The smoothed surface is self-affine with a scaling exponent $α=0.53\pm0.02$.

description: The first offshore methane hydrate recovery trial was conducted in 2013 on the north slope of the Daini Atsumi Knoll in Eastern Nankai Trough, Japan. The methane hydrate concentrated zone (MHCZ) was roughly 300 m below the seafloor and 1300 m below sea level, with a dip to the northwest by roughly 20 degrees. For the target MHCZ in Eastern Nankai Trough site, there are several kinds of heterogeneity that are observed at the site, i.e. vertical heterogeneity, lateral heterogeneity, seafloor inclination, faults and seepages. In this study, a new fully coupled THMC simulator based on implicit finite element code in COMSOL is developed to simulate methane gas extraction from the heterogeneous ground. The effects of heterogeneity in turbidity formation on hydrate dissociation and geo-mechanical behaviour, as well as gas and water production rates, are studied from the following four aspects: vertical heterogeneity, thermal response processes, lateral heterogeneity / seafloor inclination, and fault patterns. Results show vertical heterogeneity, thermal response processes, and fault patterns have relatively large impact on the hydrate dissociation behaviour and gas/water production rates. The research examines whether a model that adopts the conventional parameter averaging method provide results equivalent to the results of the layered model. Based on the research findings above, the 2013 Nankai Trough trial was reanalyzed. Results show that the updated model considering soil and hydrate heterogeneity gave better matching of the gas / water production rates and temperature at the production and monitoring wells than the models used in the previous studies.

description: We compute the dominant new physics contributions to the processes Z -> b b and B - B in the context of two representative models with extra dimensions. The main thrust of the calculations focuses on how to control the effects of the infinite tower of Kaluza-Klein modes inside the relevant one-loop diagrams. By comparing the results with the existing experimental data, most importantly those for Rb, we show that one may derive interesting lower bounds on the size of the compactification scale Mc.

How tropical are seven- and eight-particle amplitudes?

description: We study tropical Grassmanians Tr$(k,n)$ in relation to cluster algebras, and assess their applicability to $n$-particle amplitudes for $n=7,8$. In $\mathcal{N}=4$ super Yang-Mills theory, we first show that while the totally positive part of Tr$(4,7)$ may encompass the iterated discontinuity structure of the seven-point Maximally Helicity Violating (MHV) amplitude, it is too small for the Next-to-MHV helicity configuration. Then, using Tr$(4,8)$ we propose a finite set of 356 cluster $\mathcal{A}$-coordinates expected to contain the rational symbol letters of the eight-particle MHV amplitude, and discuss how the remaining square-root letters may be obtained from limits of infinite mutation sequences. Finally, we use a triangulation of the totally positive part of Tr$(3,8)$ to obtain the associated generalised biadjoint scalar amplitude in a form containing a near-minimal amount of spurious poles.
