description: In the present paper, seven species of the lichen genus Platygramme are reported from China. Two of these, Platygramme pudica and P. platyloma, are new to China and two species, Platygramme hainanensis and P. lueckingii, both from a tropical rain forest in Hainan Island, are described as new to science. The new species belong to a group within Platygramme, which is characterized by concealed discs, while the type species, P. caesiopruinosa, and some others have widely open discs. Descriptions and the known distribution of each species are given and a working key to the Chinese species is provided.

description: Superconducting boron-doped silicon films prepared by gas immersion laser doping (GILD) technique are analyzed by atom probe tomography. The resulting three-dimensional chemical composition reveals that boron atoms are incorporated into crystalline silicon in the atomic percent concentration range, well above their solubility limit, without creating clusters or precipitates at the atomic scale. The boron spatial distribution is found to be compatible with local density of states measurements performed by scanning tunneling spectroscopy. These results, combined with the observations of very low impurity level and of a sharp two-dimensional interface between doped and undoped regions show, that the Si:B material obtained by GILD is a well-defined random substitutional alloy endowed with promising superconducting properties.

Deciding to die : decision making styles and suicide
Creators: name: Qiu, Tianyou
Publisher: name: University of British Columbia
Year: 2017

description: Suicide is a leading cause of global mortality. However, despite decades of scientific and policy efforts, rates of suicide attempts have remained largely unchanged. A key reason for this is that most identified risk factors predict suicidal thoughts, but not acts. Understanding how people decide to die may help elucidate why some individuals act on their suicidal thoughts whereas others do not. The current project examined decision making styles in relations to suicidal thoughts and suicidal acts. Results showed rational decision making style differentiated attempters from ideators, with attempters exhibiting lower rational decision making style. Avoidant and dependent styles also distinguished attempters from ideators, with dependent decision makers less likely to be attempters, while the reverse was true for avoidant decision makers. As such, decision making styles may help to distinguish active suicide attempters vs. passive suicidal ideators, thus potentially contributing not only to suicide risk assessment but also intervention.
Algebraic K-Theory of ∞-Operads

description: The theory of dendroidal sets has been developed to serve as a combinatorial model for homotopy coherent operads, see [MW07, CM13b]. An ∞-operad is a dendroidal set D satisfying certain lifting conditions. In this paper we give a definition of K-groups Kn (D) for a dendroidal set D. These groups generalize the K-theory of symmetric monoidal (resp. permutative) categories and algebraic K-theory of rings. We establish some useful properties like invariance under the appropriate equivalences and long exact sequences which allow us to compute these groups in some examples. Using results from [Heu11b] and [BN12] we show that the K-theory groups of D can be realized as homotopy groups of a K-theory spectrum .

description: In recent years, utilizing water as a clean, safe, readily available and almost free of charge solvent for the syntheses of a broad spectrum of organic compounds has been comprehensively realized and proven. At first glance, it seems that water is proposed as a green replacement for the harmful and evaporable organic solvents; however, in some cases, it presents exclusive reactivity and selectivity, which could not be achieved by using conventional organic solvents. Thus, using it for induction of stereoselectivity is absoloutly vital. At this juncture, performing stereoselective organic syntheses in either water or aqueous media has been the center of attention due to remarkable and unique results and a variety of these types of reactions have been effectively and successfully conducted. In this review, we try to highlight the recent stereoselective organic reactions, performed and developed, successfully in aqueous media. Dedicated to Professor Minoo Dabiri, an Iranian scientist woman, for her continuous efforts and achievements, in the field of organic chemistry.

description: Conventional superconductors were long thought to be spin inert; however, there is now increasing interest in both (the manipulation of) the internal spin structure of the ground-state condensate, as well as recently observed long-lived, spin-polarized excitations (quasiparticles). We demonstrate spin resonance in the quasiparticle population of a mesoscopic superconductor (aluminium) using novel on-chip microwave detection techniques. The spin decoherence time obtained (∼100 ps), and its dependence on the sample thickness are consistent with Elliott–Yafet spin–orbit scattering as the main decoherence mechanism. The striking divergence between the spin coherence time and the previously measured spin imbalance relaxation time (∼10 ns) suggests that the latter is limited instead by inelastic processes. This work stakes out new ground for the nascent field of spin-based electronics with superconductors or superconducting spintronics.

DIY infrastructure – building the GLAM Workbench
Creators: name: Sherratt, Tim
Publisher: name: Zenodo
Year: 2022

description: The GLAM Workbench is a collection of Jupyter notebooks and related resources that encourages exploration of collection data from GLAM organisations (galleries, libraries, archives and museums). Using Jupyter notebooks, researchers can run live code to manipulate and analyse data – developing their skills, and learning about the possibilities of digital collections, while undertaking real research tasks. The GLAM Workbench has always sought to provide researchers with multiple pathways, responding to their interests, aims, and digital confidence. Some of the notebooks run as web apps, requiring nothing more than a couple of clicks to run. Others are aimed at more experienced coders, providing live examples of what's possible using collection APIs. Similarly, the notebooks can be used in a variety of computing contexts – one click will launch the Binder service, but for more sustained work there are options to use Docker images, Reclaim Cloud, or other cloud facilities. Different users can follow different pathways. Without direct funding or institutional support, the GLAM Workbench has sought to achieve sustainability by opening its contents and processes to reuse, collaboration, automation and integration. There is no single platform that needs to be maintained, instead the GLAM Workbench takes advantage of existing standards and technologies to connect resources as required. Most recently, tools and documentation have been added to support individuals and organisations that want to contribute to the GLAM Workbench. For example, a standardised GitHub repository template has been developed for any GLAM organisation that wants to create its own section of the GLAM Workbench (or indeed, its very own version of the GLAM Workbench).

description: Recent work has explored solver strategies for the linear system of equations arising from a spectral Galerkin approximation of the solution of PDEs with parameterized (or stochastic) inputs. We consider the related problem of a matrix equation whose matrix and right hand side depend on a set of parameters (e.g. a PDE with stochastic inputs semidiscretized in space) and examine the linear system arising from a similar Galerkin approximation of the solution. We derive a useful factorization of this system of equations, which yields bounds on the eigenvalues, clues to preconditioning, and a flexible implementation method for a wide array of problems. We complement this analysis with (i) a numerical study of preconditioners on a standard elliptic PDE test problem and (ii) a fluids application using existing CFD codes; the MATLAB codes used in the numerical studies are available online.

description: The insect cuticle is covered by a thin layer of hydrocarbons not only preventing desiccation but also playing an important role in the sexual communication of several species. In the pteromalid wasp Lariophagus distinguendus, a parasitoid of grain infesting beetles, female cuticular hydrocarbons (CHCs) elicit male courtship behaviour. We analyzed the CHC profiles of male and female L. distinguendus wasps reared on different beetle hosts by coupled gas chromatography- mass spectrometry (GC-MS). Statistical analysis of the data revealed significant differences between strains reared on different hosts, while spatially isolated strains reared on the same host produced similar profiles. CHC profiles of parasitoids reared on Stegobium paniceum were statistically distinguishable from those of wasps reared on all other hosts. A host shift from Sitophilus granarius to S. paniceum resulted in distinguishable CHC profiles of L. distinguendus females after only one generation. Considering the role of CHCs as contact sex pheromones, our data suggest that host shifts in parasitic wasps might lead to reproductive isolation of host races due to the modification of the cuticular semiochemistry.
Zhu Shunshui (1600-1682) – the influence of, on and via him during his lifetime
Creators: name: Yeung, Wai Keung Steven
Publisher: name: University of British Columbia
Year: 2017

description: Of the many Chinese who sought refuge in Japan during the middle of the seventeenth century, Zhu Shunshui 朱舜水 (1600-1682) is perhaps one of the most talked about. He fled China in 1645. In 1659, giving up all hopes on the restoration of the fallen Ming dynasty 明朝 (1368-1644) after fifteen-year’s unfruitful efforts, Shunshui decided to sojourn in Japan and sworn not to return until the Manchu 滿族 regime is driven out of China. During his stay in Japan, the prominent Mito 水戶domain lord Tokugawa Mitsukuni 徳川光圀 (1628-1701) hired him as his teacher. Mitsukuni is the founding father of the Mitogaku 水戸学, one of the most important schools of thought in Edo period (1603-1867). This school aimed to reconstruct the historiography of Japan by Chinese Neo-Confucianism principles so as to promulgate indigenous Shinto beliefs and absolute loyalty to the emperor. The close relationship between Shunshui and Mitsukuni, and the involvement of Shunshui’s students in projects initiated by Mitsukuni, including the compilation of the Dai Nihon Shi 大日本史 (The History of the Great Japan, 1906), make some scholars believe that Shunshui has dominant influence on Japan’s Neo-Confucian thoughts, if not all Edo thoughts, as well as far-fetching inspiration on Meiji Ishin 明治維新 (the Meiji Restoration, 1868). But the flow of information among brains and its effect on recipient is too dynamic to be measured. Cultural influence over time is even more difficult to trace. By investigating Shunshui’s relationship with different people and his involvement in various events in Japan during his life time, this paper aims to clarify whether the general beliefs on his influence are plausible. In case when the findings are negative, the paper will look into the causes and suggest where Shunshui’s should be.

description: Let X in V be a closed embedding, with V - X nonsingular. We define a constructible function on X, agreeing with Verdier's specialization of the constant function 1 when X is the zero-locus of a function on V. Our definition is given in terms of an embedded resolution of X; the independence on the choice of resolution is obtained as a consequence of the weak factorization theorem of Abramovich et al. The main property of the specialization function is a compatibility with the specialization of the Chern class of the complement V-X. With the definition adopted here, this is an easy consequence of standard intersection theory. It recovers Verdier's result when X is the zero-locus of a function on V. Our definition has a straightforward counterpart in a motivic group. The specialization function and the corresponding Chern class and motivic aspect all have natural `monodromy' decompositions, for for any X in V as above. The definition also yields an expression for Kai Behrend's constructible function when applied to (the singularity subscheme of) the zero-locus of a function on V.

description: In OLAP, analysts often select an interesting sample of the data. For example, an analyst might focus on products bringing revenues of at least 100 000 dollars, or on shops having sales greater than 400 000 dollars. However, current systems do not allow the application of both of these thresholds simultaneously, selecting products and shops satisfying both thresholds. For such purposes, we introduce the diamond cube operator, filling a gap among existing data warehouse operations. Because of the interaction between dimensions the computation of diamond cubes is challenging. We compare and test various algorithms on large data sets of more than 100 million facts. We find that while it is possible to implement diamonds in SQL, it is inefficient. Indeed, our custom implementation can be a hundred times faster than popular database engines (including a row-store and a column-store).

West Coast Bauhaus : a case study of the Oberlander Residence II
Creators: name: Chanel, Blouin
Publisher: name: University of British Columbia
Year: 2017

description: This thesis will consider the joining of West Coast Modernism and Bauhaus-inspired architectural elements in the design of architect Peter Oberlander and landscape architect Cornelia Hahn Oberlander’s second residence in Vancouver, the Ravine House, located on the University of British Columbia Endowments Lands. It will posit that this style hybridization results from the Oberlanders’ particular situation as forced exiles from Central Europe as well as voluntary immigrants to Vancouver. This analysis will interrogate the dichotomy between exile and immigrant architecture that is presented in the literature of West Coast architecture The methodology will consist of an analysis of the architecture produced by the German-speaking immigrant and exile communities in Los Angeles from the 1920s to the 1950s, a precursor of the West Coast modernism in Vancouver. It will consider the seminal writings of Reyner Banham and Erhard Bahr in Los Angeles: The Architecture of Four Ecologies and Weimar on the Pacific: German Exile Culture in Los Angeles and the Crisis of Modernism, with particular attention on their approaches for reading the experiences of exile and immigration in the architectural features of buildings. This approach will be applied to a case study of the Ravine House through a biographical sketch of the Oberlander’s migration as well as a formal analysis of West Coast Modernism and the Indigenous architectures it drew upon as well as the Bauhaus features of the residence.

description: This article deals with the measurement of strain in semiconductor heterostructures from convergent beam electron diffraction patterns. In particular, three different algorithms in the field of (circular) pattern recognition are presented that are able to detect diffracted disc positions accurately, from which the strain in growth direction is calculated. Although the three approaches are very different as one is based on edge detection, one on rotational averages, and one on cross correlation with masks, it is found that identical strain profiles result for an InxGa1−xNyAs1−y/GaAs heterostructure consisting of five compressively and tensile strained layers. We achieve a precision of strain measurements of 7–9·10−4 and a spatial resolution of 0.5–0.7 nm over the whole width of the layer stack which was 350 nm. Being already very applicable to strain measurements in contemporary nanostructures, we additionally suggest future hardware and software designs optimized for fast and direct acquisition of strain distributions, motivated by the present studies.

description: The Neoproterozoic Arabian-Nubian Shield (ANS) post-dates the Boring Billion (1.85−0.85 Ga), a transition dominated by extensive arc-magmatism, terrane accretion along active subduction zones. Understanding the nature of the oceanic crust fragments preserved in the ophiolite belts is essential in extrapolating the predominant style of plate tectonics during the Neoproterozoic Era. There are two ophiolite belts with controversial genetic models in the Central Eastern Desert (CED) of Egypt, namely Wadi Semna–Fawakhir–Um Gheig belt to the north, and Ghadir–Mubarak–Barramiya belt to the south. Geochemical database and magnetic data are herein integrated to envisage the tectonic setting of the dispersed ophiolite blocks within these two belts. The northern belt is dominated by NW obduction-related thrust faults and is intensely deformed by structures attributed to the Najd fault system (NFS). The southern belt is less affected by the Najd fault with NE obduction-related thrust faults. Based on various discrimination diagrams and REEs pattern, oceanic mafic-ultramafic rocks in these belts can be classified into three types, MOR, forearc and volcanic arc basalt, where the latter is MORB overprinted by arc affinity. Our proposed evolutionary model includes N-dipping subduction zones parallel to the ~ E-W Allaqi-Heiani suture with hybrid forearc-MOR affinities. The data synthesis presented here weighs with advancing accretionary orogeny along the intraoceanic subduction zones as the dominant tectonic style during the Neoproterozoic evolution of the CED rather than the retreating style of the modern western Pacific region.

description: A phase field approach for structural topology optimization which allows for topology changes and multiple materials is analyzed. First order optimality conditions are rigorously derived and it is shown via formally matched asymptotic expansions that these conditions converge to classical first order conditions obtained in the context of shape calculus. We also discuss how to deal with triple junctions where e.g. two materials and the void meet. Finally, we present several numerical results for mean compliance problems and a cost involving the least square error to a target displacement.

description: Alterations of the glucocorticoid system and of hippocampal volumes have consistently been reported in patients with major depressive disorders (MDD). The aim of the present study was to investigate whether the messenger RNA (mRNA) expression of glucocorticoid inducible genes is associated with changes in the cornu ammonis (CA) and dentate gyrus subfields. Forty-three patients with MDD and 43 healthy controls were recruited and investigated with high resolution magnetic resonance imaging. Hippocampal subfields were measured using freesurfer. Measurement of whole blood mRNA expression of glucocorticoid inducible genes serum and glucocorticoid-regulated kinase 1 (SGK1), FK506 binding protein 5 (FKBP5), and glucocorticoid induced leucine zipper (GILZ) was performed. Patients with MDD had significantly smaller volumes of CA1, CA2/3, CA4/DG, and subiculum compared to healthy controls. In the regression analysis, the factor diagnosis had a significant moderating effect on the association of SGK1 and hippocampal volumes. Patients with low expression of SGK1 had significantly smaller CA2/3 and CA4/DG volumes compared to patients with high expression of SGK1 mRNA and to healthy controls with low/high expression of SGK1, respectively. Therefore, a lack of mRNA expression of glucocorticoid inducible genes in patients with MDD that seems to correspond to a blunted cortisol response is associated with smaller hippocampal CA and dentate gyrus volumes. SGK1 seems to be particularly relevant for stress-related mental disorders.

Structural nativization, typology and complexity: noun phrase structures in British, Kenyan and Singaporean English

Publisher: name: Universität Regensburg

Subjects: subject: 420 Englisch

description: Two much-cited explanations for linguistic innovations in varieties of New Englishes are cross-linguistic influence (see Gut 2011) and simplification (see Schneider 2007: 82). Using these two notions as starting points, the present study seeks to detect effects of structural nativization in noun phrase (NP) modification in two varieties of English whose substrate languages differ strongly from a typological point of view: Singaporean and Kenyan English. The results yielded by the comparison of random samples extracted from the relevant components of the International Corpus of English in the first part of the study show striking correspondences between the preferred NP structures in the varieties at hand and NP structures in the local languages concerned, which, in the light of Mufwene's (2001, 2008) ecological theory of language change, can be interpreted as effects of language contact. The second part of the study shows that the NPs from the three varieties also differ in terms of variables which can be viewed as measures of NP complexity. What is more, the different degrees of complexity found in the samples correspond closely to predictions about the evolutionary status of the varieties at hand made by Schneider's (2007) Dynamic Model.

The Firm Balance Sheet Channel of Uncertainty Shocks
Creators: name: Zhou, Wentao
Publisher: name: Zenodo
Year: 2023

description: This paper shows both empirically and theoretically how macro uncertainty shocks affect the real economy through firms' balance sheet adjustments. I document that following an increase in macro uncertainty, firm-level capital stock and outstanding debt fall while cash holdings increase, and such capital drop and cash buildup are more pronounced among ex-ante more indebted firms. I develop a quantitative heterogeneous firm model with joint capital, cash, and debt choices to illustrate the transmission mechanism. In the model, firms fear liquidity shortages for debt repayments, thereby trading off capital investment for less debt burdens and more cash holdings as heightened uncertainty creates greater downside risk. Cash buildup is strong, especially among more indebted firms, as cash preserves internal funds for both future debt repayment and growth opportunities triggered by increased uncertainty. The model mechanism is borne out in the data. I first show that firms in a calibrated model exhibit precautionary behavior that aligns closely with data patterns. I then show that the calibrated model reproduces the observed impacts of macro uncertainty shocks at both micro and macro levels. The balance sheet channel has novel policy implications. Investment stimulus policies yield only modest effects in counteracting the impacts of uncertainty shocks, as elevated cash demand makes firms less responsive to stimulus. In sharp contrast, credit interventions, such as debt relief policy, can strongly and effectively stabilize uncertainty-driven recessions by directly mitigating the balance sheet transmission of uncertainty shocks.

description: The differentiation between living and dead bacterial endospores is crucial in many research areas of microbiology. The identification of inactivated, non-pathogenic Bacillus anthracis spores is one reason why improvement of decontamination protocols is so desirable. Another field interested in spore viability is planetary protection, a sub-discipline of astrobiology that estimates the bioburden of spacecraft prior to launch in order to avoid interplanetary cross-contamination. We developed a dedicated, rapid and cost-effective method for identifying bacterial endospores that have been inactivated and consequently show a compromised spore wall. This novel protocol is culture-independent and is based on fluorescence microscopy and propidium monoazide (PMA) as a fluorescent marker, which is suggested to bind to DNA of spores with compromised spore coat, cortex and membranes based on our results. Inactivated preparations (treated with wet heat, irradiation, ultracentrifugation) showed a significant increase in spores that were PMA stained in their core; moreover, Bacillus atrophaeus, Bacillus safensis and Geobacillus stearothermophilus seemed to be best suited for this technique, as the spore cores of all these endospores could be positively stained after inactivation. Lastly, we describe an additional counter-staining protocol and provide an example of the application of the coupled staining methods for planetary protection purposes. The introduction of this novel protocol is expected to provide an initial insight into the various possible future applications of PMA as a non-viability marker for spores in, for example, B. anthracis-related studies, food microbiology and astrobiology.
Vacuum Stability of the wrong sign $(-ϕ^{6})$ Scalar Field Theory

description: We apply the effective potential method to study the vacuum stability of the bounded from above $(-ϕ^{6})$ (unstable) quantum field potential. The stability ($\partial E/\partial b=0)$ and the mass renormalization ($\partial^{2} E/\partial b^{2}=M^{2})$ conditions force the effective potential of this theory to be bounded from below (stable). Since bounded from below potentials are always associated with localized wave functions, the algorithm we use replaces the boundary condition applied to the wave functions in the complex contour method by two stability conditions on the effective potential obtained. To test the validity of our calculations, we show that our variational predictions can reproduce exactly the results in the literature for the $\mathcal{PT}$-symmetric $ϕ^{4}$ theory. We then extend the applications of the algorithm to the unstudied stability problem of the bounded from above $(-ϕ^{6})$ scalar field theory where classical analysis prohibits the existence of a stable spectrum. Concerning this, we calculated the effective potential up to first order in the couplings in $d$ space-time dimensions. We find that a Hermitian effective theory is instable while a non-Hermitian but $\mathcal{PT}$-symmetric effective theory characterized by a pure imaginary vacuum condensate is stable (bounded from below) which is against the classical predictions of the instability of the theory. We assert that the work presented here represents the first calculations that advocates the stability of the $(-ϕ^{6})$ scalar potential.

description: We resurrect Eddington's proposal for the gravitational action in the presence of a cosmological constant and extend it to include matter fields. We show that the Newton-Poisson equation is modified in the presence of sources and that charged black holes show great similarities with those arising in Born-Infeld electrodynamics coupled to gravity. When we consider homogeneous and isotropic space-times we find that there is a minimum length (and maximum density) at early times, clearly pointing to an alternative theory of the Big Bang. We thus argue that the modern formulation of Eddington's theory, Born-Infeld gravity, presents us with a novel, non-singular description of the Universe.

description: Lipid rafts have been shown to play an important role for G-protein mediated signal transduction and the function of ligand-gated ion channels including their modulation by psychopharmacological compounds. In this study, we investigated the functional significance of the membrane distribution of NMDA and GABAA receptor subunits in relation to the accumulation of the tricyclic antidepressant desipramine (DMI) and the benzodiazepine diazepam (Diaz). In the presence of Triton X-100, which allowed proper separation of the lipid raft marker proteins caveolin-1 and flotillin-1 from the transferrin receptor, all receptor subunits were shifted to the non-raft fractions. In contrast, under detergent-free conditions, NMDA and GABAA receptor subunits were detected both in raft and non-raft fractions. Diaz was enriched in non-raft fractions without Triton X-100 in contrast to DMI, which preferentially accumulated in lipid rafts. Impairment of lipid raft integrity by methyl-β-cyclodextrine (MβCD)-induced cholesterol depletion did not change the inhibitory effect of DMI at the NMDA receptor, whereas it enhanced the potentiating effect of Diaz at the GABAA receptor at non-saturating concentrations of GABA. These results support the hypothesis that the interaction of benzodiazepines with the GABAA receptor likely occurs outside of lipid rafts while the antidepressant DMI acts on ionotropic receptors both within and outside these membrane microdomains.

description: Benzofuran itself is an oily chemical compound, extracted from coal tar, which is converted into a synthetic resin, used in different industries. Several derivatives of benzofuran occur naturally in some plants and are the scaffold in several natural products. However, most of them are synthesized via different synthetic routes. In this chapter, we try to highlight the recent advances in the synthetic approaches to this important heterocyclic system and wide variety of its derivatives.

description: The degree zero part of the quantum cohomology algebra of a smooth Fano toric symplectic manifold is determined by the superpotential function, W, of its moment polytope. In particular, this algebra is semisimple, i.e. splits as a product of fields, if and only if all the critical points of W are non-degenerate. In this paper we prove that this non-degeneracy holds for all smooth Fano toric varieties with facet-symmetric duals to moment polytopes.

Asymptotic normality through factorial cumulants and partitions identities

description: In the paper we develop an approach to asymptotic normality through factorial cumulants. Factorial cumulants arise in the same manner from factorial moments, as do (ordinary) cumulants from (ordinary) moments. Another tool we exploit is a new identity for "moments" of partitions of numbers. The general limiting result is then used to (re-)derive asymptotic normality for several models including classical discrete distributions, occupancy problems in some generalized allocation schemes and two models related to negative multinomial distribution.
Net ecosystem carbon balance for a peat bog undergoing restoration by integrating flux tower and aquatic flux measurements
Creators: name: D'Acunha, Brenda
Publisher: name: University of British Columbia
Year: 2017

description: Peatlands are wetlands where gross primary production exceeds organic matter decomposition causing an accumulation of partially decomposed matter, also called peat. Peat ecosystems can accumulate more carbon (C) than tropical rainforests. However, dissolved fluxes of C (as dissolved organic carbon (DOC), carbon dioxide (CO₂) and methane (CH₄)) must also be considered to determine if these ecosystems are net sinks or sources of greenhouse gases (GHGs) to the atmosphere. This research was conducted in Burns Bog, Delta, BC, Canada, one of the largest bogs on the west coast of the Americas, but which has been heavily impacted by a range of human activities. Currently, ecological restoration efforts are underway by a large-scale ditch blocking program, with the aim of re-establishing water table conditions that promote peat accumulation. Here I present data on ecosystem-scale fluxes of CO₂ and CH4 determined by eddy covariance (EC), together with data on (i) evasion fluxes of CO₂ and CH₄ from the water surface, and (ii) the flux and characteristics of DOC in water draining Burns Bog. The net ecosystem carbon balance (NECB) was determined as the sum of EC fluxes and DOC export. Concentrations of dissolved CO₂ and CH₄ were determined by headspace equilibration, and evasion rates from the water surface were quantified and used to estimate the role of the hydrosphere in the ecosystem-scale measurements. Water samples collected from five saturated areas in the flux tower footprint were analyzed for DOC concentrations and characteristics. Satellite imaging showed that during the dry season 10% of the area was covered by water, while on the wet season, it was 60%. The hydrosphere was found to be a continual C source, emitting 271 g C m-² yr-¹. NECB was found to be -98 g C m-² yr-¹. DOC export was found to offset about 60% of the apparent net C emissions determined by EC during the wet season and 3% of the net C uptake during the dry season, indicating that the EC measurements by themselves underestimate C emissions during the wet season and overestimate C accumulation in the dry season by not accounting for DOC drainage.

description: The ability of plants to serve as a production system for bacterial lipoprotein vaccines has been investigated. First, the effect of high-level expression of the Borrelia burgdorferi outer membrane protein A (OspA), a prototype vaccine against Lyme disease, has been examined by a proteomics approach. Analysis by 2D-PAGE of wild type tobacco plants and transplastomic plants accumulating recombinant OspA showed no apparent differences in protein pattern except for OspA. However, presence of the bacterial signal sequence limits transgene accumulation. As an alternative approach OspA was produced in Nicotiana benthamiana plants by transient expression via a deconstructed tobacco mosaic virus-based system. While rapid expression of OspA could be achieved, no palmitoylation occurred with the genuine bacterial sequence. In contrast, modification of the N-terminus with an eukaryotic sequence motif resulted in palmitoylation of OspA. This study shows that plants provide multiple expression strategies and could serve as a versatile production platform for recombinant lipidated subunit vaccines.

description: For every $p$-group of order $p^n$ with the derived subgroup of order $p^m$, Rocco in \cite{roc} has shown that the order of tensor square of $G$ is at most $p^{n(n-m)}$. In the present paper not only we improve his bound for non-abelian $p$-groups but also we describe the structure of all non-abelian $p$-groups when the bound is attained for a special case. Moreover, our results give as well an upper bound for the order of $π_3(SK(G, 1))$.
