Naja kaouthia

description: Naja kaouthia Lesson, 1831 Material examined. BANGLADESH • 1 adult; Sylhet Division, Moulvibazar District, Kamalganj Upazila, LNP, Chevron station; 24°19.85′N, 091°47.71′E; 11 Jun. 2011; photo voucher ZRC (IMG) 2.402. Identification. Naja kaouthia is a large brown cobra, which in northeast Bangladesh lacks rings; the head is broad and there is a unique monocle marking on the back of the hood (Das 2010). The throat of the vouchered specimen was yellowish tan with a pale, slightly mottled section from ventrals 9–14 and a progressively darker gray section from ventrals 15–22. Habitat. This is primarily a snake of tea plantations and degraded forest in LNP, though it was occasionally observed in paddy fields and village habitat. Remarks. SCR observed one instance of a N. kaouthia spitting venom, an unusual but not unknown behavior among species of Naja.

title: Biogeochemistry of cyanobacterial blooms in the Baltic Sea

Year: 2024
Subjects: Ecosystem observation, processes and dynamics

description: No abstracts are to be cited without prior reference to the author.Summer blooms of filamentous heterocystous cyanobacteria have been a persistent feature of the Baltic ecosystem, especially in recent decades. The occurrence, duration, extension, and intensity of the blooms vary from year to year, while our ability to predict them quantitatively is still limited. One of the major large-scale biogeochemical drivers of the blooms are opposite variations of nitrogen and phosphorus pools caused by long-term dynamics of hypoxic zone. The expansion of hypoxia leads to a reduction of dissolved inorganic nitrogen pool through denitrification and to an increase of dissolved phosphate pool through internal loading. Simultaneous nitrogen depletion and phosphorus enrichment result in a shift of marine ecosystem towards nitrogen limitation, which is favourable for nitrogen fixation by cyanobacteria that generate additional nitrogen source to the nitrogen-limited ecosystem comparable to external inputs from the land and atmosphere. The shrinkage of the hypoxic zone through improved oxygen supply induces opposite consequences. Thus, because of the biogeochemical peculiarities of the Baltic Sea, the environmental significance of the Baltic diazotrophic cyanobacteria goes far beyond the damage caused by toxicity and recreational nuisance of other HABs. The increase in primary production and sedimentation of organic matter caused by nitrogen fixation results in higher oxygen consumption and further expansion of hypoxia. This positive feedback in biogeochemical cycling affects numerous and diverse ecosystem links, from foodweb interactions and dynamics of fish populations to counteraction of anthropogenic reductions of the nitrogen load.

description: We used a recent grid of stellar models computed with and without rotation to make predictions concerning the WR populations and the frequency of different types of core-collapse SNe. Current rotating models were checked to provide good fits to the following features: solar luminosity and radius at the solar age, main-sequence width, red-giant and red-supergiant (RSG) positions in the HRD, surface abundances, and rotational velocities. Rotating stellar models predict that about half of the observed WR stars and at least half of the type Ibc SNe may be produced through the single-star evolution channel. Rotation increases the duration of the WNL and WNC phases, while reducing those of the WNE and WC phases, as was already shown in previous works. Rotation increases the frequency of type Ic SNe. The upper mass limit for type II-P SNe is \sim 19.0 MSun for the non rotating models and \sim 16.8 MSun for the rotating ones. Both values agree with observations. Moreover, present rotating models provide a very good fit to the progenitor of SN 2008ax. We discuss future directions of research for further improving the agreement between the models and the observations. We conclude that the mass-loss rates in the WNL and RSG phases are probably underestimated at present. We show that up to an initial mass of 40 M\odot, a surface magnetic field inferior to about 200 G may be sufficient to produce some braking. Much lower values are needed at the red supergiant stage. We suggest that the presence/absence of any magnetic braking effect may play a key role in questions regarding rotation rates of young pulsars and the evolution leading to LGRBs.

description: S. Kondo has constructed a ball quotient compactification for the moduli space of non-hyperelliptic genus four curves. In this paper, we show that this space essentially coincides with a GIT quotient of the Chow variety of canonically embedded genus four curves. More specifically, we give an explicit description of this GIT quotient, and show that the birational map from this space to Kondo's space is resolved by the blow-up of a single point. This provides a modular interpretation of the points in the boundary of Kondo's space. Connections with the slope nine space in the Hassett-Keel program are also discussed.

Comparative persistence of tumor necrosis factor alpha antagonists in patients with rheumatoid arthritis
Creators: name: Fisher, Anat
Publisher: name: University of British Columbia
Year: 2012

description: Introduction: This thesis comprises three studies examining treatment persistence with tumour necrosis factor alpha (TNFα) antagonists in rheumatoid arthritis (RA) patients. Persistence, also commonly known as duration of treatment, has been suggested as an indirect measure that balances benefit and harm, and it is important for cost-effectiveness analysis and budget planning. Previous research has examined the effect of drug and patient characteristics on persistence with TNFα antagonists. Objectives: 1) To estimate pairwise comparative persistence with TNFα antagonists infliximab, adalimumab and etanercept in RA patients; 2) To evaluate the impact of investigator factors (methods) and of prescriber factors (propensity for discontinuation and preference for prescribed drug) on comparative persistence estimates with TNFα antagonists in RA patients . Methods: To address these objectives, three population-based studies of an RA cohort were conducted in British Columbia patients using survival analysis methodology. Results: 1) In RA patients similar persistence was observed with infliximab, adalimumab and etanercept, with median persistence equaling approximately 3.5 years; 2) The length of ‘drug-free interval’ used to ascertain drug discontinuation influences the observed magnitude and significance of comparative persistence estimates; 3) Physician factors (prescribing habits) are predictors and possible confounding factors in studies of persistence and comparative persistence. Conclusions: This thesis provides evidence showing that researchers and physicians can influence estimated and actual comparative persistence on TNFα antagonists in RA patients. The role of researchers and physicians in affecting estimates of persistence may explain heterogeneity in these estimates across different studies. Improved methodology in conducting comparative persistence research is needed to establish a high quality body of evidence for the use of patients, clinicians, researchers and policy makers.
Realistic limits on the nonlocality of an N-partite single-photon superposition

description: A recent paper [L. Heaney, A. Cabello, M. F. Santos, and V. Vedral, New Journal of Physics, 13, 053054 (2011)] revealed that a single quantum symmetrically delocalized over N modes, namely a W state, effectively allows for all-versus-nothing proofs of nonlocality in the limit of large N. Ideally, this finding opens up the possibility of using the robustness of the W states while realizing the nonlocal behavior previously thought to be exclusive to the more complex class of Greenberger-Horne-Zeilinger (GHZ) states. We show that in practice, however, the slightest decoherence or inefficiency of the Bell measurements on W states will degrade any violation margin gained by scaling to higher N. The non-statistical demonstration of nonlocality is thus proved to be impossible in any realistic experiment.

Identification. This is a medium-sized viper identified by its green color, brown-spotted tail, keeled temporal scales, and 23 midbody scale rows (Das 2010). Taxonomic notes. Trimeresurus were common in the roadkill survey, but many specimens were too damaged to identify to species, and the rest were identified at the time as T. albolabris, which we now believe were misidentifications. The Trimeresurus found in LNP during the nocturnal visual surveys since 2014 were definitively identified as T. erythrurus, but it is possible that additional green pit viper species are present in the park. Habitat. This species was typically encountered in mature and degraded forest, although several specimens also showed up in tea plantations. It was usually found hanging motionless from low vegetation, waiting for prey. On occasion specimens were found on the ground during heavy rains.

description: No abstracts are to be cited without prior reference to the author.Toxic phytoplankton has been monitored in 3 Icelandic fjords (Hvalfjordur, Breidifjordur, Eyjafjordur) from 2005 to 2009, in connection with culturing and harvesting of blue mussel Mytilus edulis. Phytoplankton was sampled every week from spring to autumn each year for screening toxic species (net samples) and for cell counting (water samples). Toxic species of two genera of dinoflagellates (i.e. Dinophysis and Alexandrium) and one genus of diatoms (Pseudo-nitzschia) were found. Dinophysis spp were found in all the fjords every year with growth period from June to December. Highest concentration (17000 c/l) of Dinophysis spp was found in Hvalfjordur and cell numbers in the other fjords often reached several thousands pr litre. Alexandrium spp was found in all three fjords with highest cell numbers in Eyjafjordur. In 2009 Alexandrium spp was extremely abundant (max 16000 c/l) in Breidifjordur and Eyjafjordur for several weeks but with lower concentration in Hvalfjordur. The main growth period for Alexandrium spp was from late June to middle of August. High variability was found from year to year in both cell numbers and time of occurence for Dinophysis spp and Alexandrium spp in all three fjords. DSP and PSP haave been registered in the mussel in 2007 to 2009 in and after periods of high cell numbers. Pseudo-nitzscia spp was found in all three fjord with great variability in numbers between years. Although Pseudonitzschia spp has been registered in very high concentration on numerous occations, measurments of ASP have always been negative. All the areas have been closed for harvesting during several weeks each year due to high concentrations of toxic phytoplankton

description: No abstracts are to be cited without prior reference to the author.The Curonian Lagoon is the largest lagoon of the Europe separated from the Baltic Sea by narrow sand spits (total area 1584 km2 , mean depth 3.8 m, maximum depth 5 m) (Fig. 1). The Lagoon is playing an important part in many fields of economy of Russia (Kaliningrad region) and Lithuania. In XX century in the Baltic Sea and its coastal lagoons the eutrophication of waters increased due to increase nutrients loading, and simultaneously climatic changes were observed (HELCOM 2002, 2007). The Curonian Lagoon receives water from the River Nemunas, the third-largest contributor of total nitrogen and phosphorus to the Baltic Sea. Until the late 1980s nutrients loading exceeded by many times the permissible nutrients loading leading to eutrophication of lagoon. Multiple reductions of nutrients loading from the watershed area in 1990s owing to the economic crisis in Russia did not result in considerable improvement of the ecological situation. Ongoing eutrophication is one of the most important problems of the Curonian Lagoon. Eutrophication affects all trophic levels and primarily on blooming of Cyanobacteria

description: The present research examines the link between High-Performance Work Practices (HPWP) and organizationalambidexterity. A quantitative research approach was used in this study and a structured questionnaire was administered to400 employees from Infosys, TCS, HCLTech, Tech Mahindra and other IT firms in India. The data was collected throughonline questionnaires and participants were selected based on the stratified random sampling technique in order to get theparticipants from different organizational level. The results showed that there is a positive correlation between HPWP andorganizational ambidexterity, which underlines the importance of carefully developed HR practices for improving theemployees’ competencies and organizational flexibility.The study adds to theory by providing a framework that links HR practices and ambidexterity and offers practicalimplications for managers who seek to manage for competitiveness in competitive and dynamic contexts. Future researchcould build on the present framework by including other mediating factors such as, organizational learning and employees’well-being, or by investigating the relationship between digital HR practices and ambidexterity. This research holds seriouslessons for organisations that wish to maintain innovation and efficiency by adopting SHRM.

description: The formation of intracluster light and of the extended halos around brightest cluster galaxies is closely related to morphological transformation, tidal stripping, and disruption of galaxies in clusters. We analyze Ks- and V-band surface photometry as well as deep long-slit spectra, and establish a link between the structures in the light distribution, the absorption line kinematics, and the LOS velocity distributions of nearby galaxies and planetary nebulae (PNs). The central galaxy NGC 3311 is surrounded by an extended symmetric outer halo with n=10 and an additional, off-centered envelope ~ 50" to the North-East. Its luminosity L_V= 1.2x10^{10} +/- 6.0 x 10^8 L_sun corresponds to ~50 % of the luminosity of the symmetric halo in the same region. Based on measured PN velocities, at least part of the off-centered envelope consists of high-velocity accreted stars. We have also discovered two tidal streams in the cluster center, emerging from the dwarf galaxy HCC 026 and from the S0 galaxy HCC 007. The HCC 026 stream is redshifted by ~1200 km/s with respect to NGC 3311, similarly as HCC 026 itself, a fraction of PNs in the off-centered envelope, and several other dwarf galaxies nearby. The stars in one of the HCC 026 tails are known to be consistent with the low-metallicity population of HCC 026, and our photometry shows that this galaxy is already mostly dissolved in the tidal field. The tidal stream around HCC 007 extends over at least 110 kpc. It is fairly thick and is brighter on the side of the asymmetric outer halo of NGC 3311, which it may join. Its luminosity is several 10^9 L_sun, similar to the luminosity of the stripped-down galaxy HCC 007. The redshift of the stream is determined from a few PN velocities and is similar to that for HCC 007 and HCC 026.

description: Given a group G, a (unital) ring A and a group homomorphism $σ: G \to \Aut(A)$, one can construct the skew group ring $A \rtimes_σ G$. We show that a skew group ring $A \rtimes_σ G$, of an abelian group G, is simple if and only if its centre is a field and A is G-simple. If G is abelian and A is commutative, then $A \rtimes_σ G$ is shown to be simple if and only if σis injective and A is G-simple. As an application we show that a transformation group (X,G), where X is a compact Hausdorff space and G is abelian, is minimal and faithful if and only if its associated skew group algebra $C(X) \rtimes_σ G$ is simple. We also provide an example of a skew group algebra, of an (non-abelian) ICC group, for which the above conclusions fail to hold.

description: No abstracts are to be cited without prior reference to the author.Studies have shown that numerous diatom species can assimilate organic nitrogen (Antia et al., 1991), but the influence of organic nitrogen sources on harmful diatoms blooms is poorly known. That is the case for diatom species of the genus Pseudo-nitzschia which produce domoic acid (DA), a neurotoxin responsible for amnesic shellfish contaminations (Bates & Trainer, 2006). Few studies have reported the growth of Pseudo-nitzschia species on organic nitrogen and only with urea and glutamine (Hillebrand & Sommer, 1996 ; Howard et al., 2007 ; Thessen et al., 2009). Moreover, the role of amino acid nutriments on their toxicity has not been elucidated. In the present work, we demonstrate the influence of different mineral and organic nitrogen sources on the growth and domoic acid content of the toxic strains P. multiseries CCL70 and P. australis C1, isolated from English Channel waters.

description: This paper deals with maximum entropy completion of partially specified block-circulant matrices. Since positive definite symmetric circulants happen to be covariance matrices of stationary periodic processes, in particular of stationary reciprocal processes, this problem has applications in signal processing, in particular to image modeling. In fact it is strictly related to maximum likelihood estimation of bilateral AR-type representations of acausal signals subject to certain conditional independence constraints. The maximum entropy completion problem for block-circulant matrices has recently been solved by the authors, although leaving open the problem of an efficient computation of the solution. In this paper, we provide an effcient algorithm for computing its solution which compares very favourably with existing algorithms designed for positive definite matrix extension problems. The proposed algorithm benefits from the analysis of the relationship between our problem and the band-extension problem for block-Toeplitz matrices also developed in this paper.

description: Subhorizon approximation is often used in cosmological perturbation theory. In this paper, however, it is shown that the subhorizon approximation is not always a good approximation at least in case of $k$-essence model. We also show that the sound speed given by $k$-essence model exerts a huge influence on the time evolution of the matter density perturbation, and the future observations could clarify the differences between the $Λ$CDM model and $k$-essence model.

description: No abstracts are to be cited without prior reference to the author.Domoic acid (DA) is a naturally occurring toxin produced by pennate diatoms, mainly from several species of the Pseudo-nitzschia genus. Accumulation of DA in shellfish through filter feeding on toxic producing Pseudo-nitzschia can lead to Amnesic Shellfish Poisoning (ASP) intoxication in humans. A synthetic resin (Sepabeads® SP-700, Mitsubishi Chemical Corporation) was assessed and selected for its ability to adsorb DA dissolved in the water column. Our aim was to use the SP-700 resin in a new monitoring tool to track the variation of DA concentration produced during Pseudo-nitzschia blooms in Scottish waters
Studies in the urban domestic housing of mid-Republican Sicily (ca. 211 - 70 BC) : aspects of cross-cultural contact

description: This study provides a systematic analysis of urban domestic housing in Sicily during the mid-Republican period (ca. 211 – 70 BC). It employs a methodological framework that is not grounded in traditional typologies, and instead uses relevant comparative and contextual models. The data are examined for the socio-cultural impact of Roman hegemony on Rome’s first province. The aim is to gain a better understanding of the nature of cross-cultural contact in the region, and, where possible, to interpret developing Sicilian ideologies and identities during this period. It was found that the domestic architecture and their decorative pavements suggest a mixture of Greek, Punic, Roman, and regional Sicilian cultural influences, stimuli, and interactions along a variable scale, but more significantly that Sicily, which was geographically central, and culturally diverse, acted as a ‘middle ground’, and had an active role in the (re)interpretation and dissemination of many of these features across the Mediterranean. This is particularly true for the colonnaded courtyard, the western tradition of decorative pavements, and the communal domestic bath-suite. Further, it was recognised that variable responses are relative primarily to 1) house type; 2) location within the island (possibly related to ethnic or cultural affiliation); 3) social status; and 4) function. There is an apparent dichotomy within the houses between the more ‘private’ domestic spaces, which largely maintain more traditional Greek or Punic features, and the ‘public’ reception spaces, which, while they belong to a Mediterranean-wide koine, begin to incorporate features more common to the Roman west. All of these variables themselves were likely to have been interrelated. Sicily, being Rome’s first province, is fundamental to any discussion about culture contact under Roman hegemony. The material manifestations of cross-cultural contact during the mid-Republican period as represented by the urban domestic architecture suggest a combination of multidirectional processes and multi-layered identities. This study represents a launch-point for further analyses of the impact of culture contact by illustrating some of the processes involved in the overarching practice of so-called ‘Romanisation’. It also provides a worthwhile approach to analyse other material assemblages in Sicily, as well as in other ‘new’ Roman provinces.

description: No abstracts are to be cited without prior reference to the author.• despite low growth rates, (harmful) dinoflagellates can rapidly build up blooms with high biomass concentrations • life cycle processes (en- and excystment) are assumed to affect formation, magnitude, and termination of blooms, but also the dominance and seasonal succession of species (e.g. Anderson and Rengefors 2006, and Kremp et al., 2008) • current coupled biological-physical models hardly consider life cycle processes (Hense, 2010) • we aim to formulate a general model framework for the life cycle of dinoflagellates; this is realized by literature research and by using data from laboratory experiments • based on a conceptual model (Fig. 1) we have developed a numerical model to examine the regulation of dinoflagellate bloom dynamics through life cycle processes

description: Ruprecht 147 is a hitherto unappreciated open cluster that holds great promise as a standard in fundamental stellar astrophysics. We have conducted a radial velocity survey of astrometric candidates with Lick, Palomar, and MMT observatories and have identified over 100 members, including 5 blue stragglers, 11 red giants, and 5 double-lined spectroscopic binaries (SB2s). We estimate the cluster metallicity from spectroscopic analysis, using Spectroscopy Made Easy (SME), and find it to be [M/H] = +0.07 \pm 0.03. We have obtained deep CFHT/MegaCam g'r'i' photometry and fit Padova isochrones to the (g' - i') and 2MASS (J - K) CMDs using the τ^2 maximum-likelihood procedure of Naylor (2009), and an alternative method using 2D cross-correlations developed in this work. We find best fits for isochrones at age t = 2.5 \pm 0.25 Gyr, m - M = 7.35 \pm 0.1, and A_V = 0.25 \pm 0.05, with additional uncertainty from the unresolved binary population and possibility of differential extinction across this large cluster. The inferred age is heavily dependent by our choice of stellar evolution model: fitting Dartmouth and PARSEC models yield age parameters of 3 Gyr and 3.25 Gyr respectively. At approximately 300 pc and 3 Gyr, Ruprecht 147 is by far the oldest nearby star cluster.

description: We have studied polycrystalline Yb4LiGe4, a ternary variant of the R5T4 family of layered compounds characterized by a very strong coupling between the magnetic and crystallographic degrees of freedom. The system is mixed valent, with non-magnetic Yb2+ and magnetic Yb3+ present, and is characterized by coexisting ferromagnetic and antiferromagnetic correlations. We present measurements of resistivity, AC-susceptibility, specific heat, and muon spin relaxation (muSR), below 1 K. The low temperature measurements suggest a transition to a mesoscopically inhomogeneous magnetically ordered state below 2 K characterized by fluctuations well below the ordering temperature. This unusual state is believed to result from the enhanced two-dimensionality produced by Li substitution and frustration effects inherent in the Yb sub-lattice geometry.

description: Analysis of execution traces plays a fundamental role in many program analysis approaches, such as runtime verification, testing, monitoring, and specification mining. Execution traces are frequently parametric, i.e., they contain events with parameter bindings. Each parametric trace usually consists of many meaningful trace slices merged together, each slice corresponding to one parameter binding. This gives a semantics-based solution to parametric trace analysis. A general-purpose parametric trace slicing technique is introduced, which takes each event in the parametric trace and dispatches it to its corresponding trace slices. This parametric trace slicing technique can be used in combination with any conventional, non-parametric trace analysis technique, by applying the later on each trace slice. As an instance, a parametric property monitoring technique is then presented. The presented parametric trace slicing and monitoring techniques have been implemented and extensively evaluated. Measurements of runtime overhead confirm that the generality of the discussed techniques does not come at a performance expense when compared with existing parametric trace monitoring systems.

description: LWA1 is a new radio telescope operating in the frequency range 10-88 MHz, located in central New Mexico. The telescope consists of 258 pairs of dipole-type antennas whose outputs are individually digitized and formed into beams. Simultaneously, signals from all dipoles can be recorded using one of the instrument's "all dipoles" modes, facilitating all-sky imaging. Notable features of the instrument include high intrinsic sensitivity (about 6 kJy zenith system equivalent flux density), large instantaneous bandwidth (up to 78 MHz), and 4 independently-steerable beams utilizing digital "true time delay" beamforming. This paper summarizes the design of LWA1 and its performance as determined in commissioning experiments. We describe the method currently in use for array calibration, and report on measurements of sensitivity and beamwidth.

description: A new diketopiperazine cyclo-(L-Phe-N-ethyl-L-Glu) (1), along with two known diketopiperazines cyclo-(L-Pro-L-Leu) (2) and cyclo-(L-Pro-L-Phe) (3) were isolated from the cultures of an endophytic fungus Aspergillus aculeatus F027. The structures of these compounds were elucidated based on spectroscopic data. The configurations of these compounds were determined by advanced Marfey’s analysis. Antibacterial activity of the diketopiperazines against Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa were also evaluated.

description: We reexamine some aspects of scattering by a Schwarzschild black hole in the framework of complex angular momentum techniques. More precisely, we consider, for massive scalar perturbations, the high-energy behavior of the resonance spectrum and of the absorption cross section by emphasizing analytically the role of the mass. This is achieved (i) by deriving asymptotic expansions for the Regge poles of the $S$-matrix and then for the associated weakly damped quasinormal frequencies and (ii) by taking into account the analytic structure of the greybody factors which allows us to extract by resummation the physical information encoded in the absorption cross section.

Linear model selection based on extended robust least angle regression
Creators: name: Zhang, Hongyang
Publisher: name: University of British Columbia
Year: 2012

description: In variable selection problems, when the number of candidate covariates is relatively large, the "two-step" model building strategy, which consists of two consecutive steps sequencing and segmentation, is often used. Sequencing aims to first sequence all the candidate covariates to form a list of candidate variables in which more "important" ones are likely to appear at the beginning. Then, in the segmentation step, the subsets of the first m (chosen by the user) candidate covariates which are ranked at the top of the sequenced list will be carefully examined in order to select the final prediction model. This thesis mainly focuses on the sequencing step. Least Angle Regression (LARS), proposed by Efron, Hastie, Johnstone and Tibshirani (2004), is a quite powerful step-by-step algorithm which can be used to sequence the candidate covariates in order of their importance. Khan, J.A., Van Aelst, S., and Zamar, R.H. (2007) further proposed its robust version --- Robust LARS. Robust LARS is robust against outliers and computationally efficiency. However, neither the original LARS nor the Robust LARS is available for carrying out the sequencing step when the candidate covariates contain both continuous and nominal variables. In order to remedy this, we propose the Extended Robust LARS by proposing the generalized definitions of correlations which includes the correlations between nominal variables and continuous variables. Simulations and real examples are used to show that the Extended Robust LARS gives superior performance to two of its competitors, the classical Forward Selection and Group Lasso.
