Scolecodes

description: Genus Scolecodes Illg, 1958
Diagnosis. Body vermiform, elongate, cylindrical, usually curved or coiled, consisting of prosome incorporating all pedigerous somites and small abdomen. Cephalosome expanded laterally, but fused with or obscurely defined from metasome. Swimming legs confined to anterior part of prosome, separated from one another by regular intervals. Fourth pedigerous somite much longerthan remainingpartofbody, formingbroodpouchincorporating fifth pedigerous somite. Genital openings located posteriorly on prosome. Abdomen 1-segmented, small, incompletely articulated from prosome. Caudal rami distinct, armed with 6 small setae. Rostrum as anterior prominence on cephalosome. Antennule unsegmented, consistingof extremely expanded, globular proximal part and narrow distal part; armed with several setae on both parts. Antenna 2- or 3-segmented; terminal segment (endopod) terminating in claw, with few setae. Labrum obscure, notcovering mouthparts. Mandible and maxillule lobate, bearing several setae. Maxilla unsegmented or incompletely 2-segmented, with 3 or 4 setae. Maxilliped absent. Legs 1–4 broad, biramous, each with 1- or 2- segmented protopod. Basis with outer seta in all legs; basis of leg 1 lacking innerdistal element. Exopods 1- or 2-segmented; endopods unsegmented. Setaeon rami mostly short, broad, spiniform, with nipple-like tip. Leg 4 with or without inner coxal seta. Leg 5 absent.
Type species. Scolecodes huntsmani (Henderson, 1930) by original designation.
Remarks. Illg (1958) established the genus Scolecodes to accommodate Scolecimorpha huntsmani Henderson, 1931 and redescribed this species on the basis of newly collected specimens associated with Styela gibbsii Stimpson, 1864, the type host, and Pyura hauster (Stimpson, 1864) from Washington, near the type locality in British Columbia, Canada. Dudley (1966) recorded Boltenia villosa (Stimpson, 1864) as an additional host of this copepod, also from Washington State. Illg (1970b) recorded the discovery of this species associated with Cnemidocarpa fertilis (Hartmeyer, 1906) and C. finmarkiensis (Kiaer, 1893) in Japanese waters.
The genus Scolecodes appears to be related to Campodelphys gen. nov., especiallyinleg form. However, comparedto Campodelphys gen. nov., in Scolecodes the body is more elongate, the prosome isexpanded to include all the pedigerous somites plus the genital somite, and the free abdomen is unsegmented. In addition, the maxilliped is absent in Scolecodes but present in Campodelphys gen. nov.

description: Adhesive peeling of a thin elastic film from a substrate is a classic problem in mechanics. However, many of the investigations on this topic to date have focused on peeling from substrates with flat surfaces. In this paper, we study the problem of peeling an elastic thin film from a rigid substrate that has periodic surface undulations. We allow for contact between the detached part of the film with the substrate. We give analytical results for computing the equilibrium force given the true peeling angle, which is the angle at which the detached part of the film leaves the substrate. When there is no contact we present explicit results for computing the true peeling angle from the substrate's profile and for determining an equilibrium state's stability solely from the substrate's surface curvature. The general results that we derive for the case involving contact allow us to explore the regime of peeling at large surface roughnesses. Our analysis of this regime reveals that the peel-off force can be made to become independent of the peeling direction by roughening the surface. This result is in stark contrast to results from peeling on flat surfaces, where the peel-off force strongly depends on the peeling direction. Our analysis also reveals that in the large roughness regime the peel-off force achieves its theoretical upper bound, irrespective of the other particulars of the substrate's surface profile.

description: We study geometric structures of $\mathcal{W}_4$-type in the sense of A. Gray on a Riemannian manifold. If the structure group $\mathrm{G} \subset \SO(n)$ preserves a spinor or a non-degenerate differential form, its intrinsic torsion $Γ$ is a closed 1-form (Proposition \ref{dGamma} and Theorem \ref{Fixspinor}). Using a $\mathrm{G}$-invariant spinor we prove a splitting theorem (Proposition \ref{splitting}). The latter result generalizes and unifies a recent result obtained in \cite{Ivanov&Co}, where this splitting has been proved in dimensions $n=7,8$ only. Finally we investigate geometric structures of vectorial type and admitting a characteristic connection $\nabla^{\mathrm{c}}$. An interesting class of geometric structures generalizing Hopf structures are those with a $\nabla^{\mathrm{c}}$-parallel intrinsic torsion $Γ$. In this case, $Γ$ induces a Killing vector field (Proposition \ref{Killing}) and for some special structure groups it is even parallel.

Money Transfer Made Simple: a Specification, a Generic Algorithm, and its Proof

description: It has recently been shown that, contrarily to a common belief, money transfer in the presence of faulty (Byzantine) processes does not require strong agreement such as consensus. This article goes one step further: namely, it first proposes a non-sequential specification of the money-transfer object, and then presents a generic algorithm based on a simple FIFO order between each pair of processes that implements it. The genericity dimension lies in the underlying reliable broadcast abstraction which must be suited to the appropriate failure model. Interestingly, whatever the failure model, the money transfer algorithm only requires adding a single sequence number to its messages as control information. Moreover, as a side effect of the proposed algorithm, it follows that money transfer is a weaker problem than the construction of a safe/regular/atomic read/write register in the asynchronous message-passing crash-prone model.

description: We identify a set of higher-derivative extensions of Einstein-Maxwell theory that allow for spherically symmetric charged solutions characterized by a single metric function $f(r)=-g_{tt}=1/g_{rr}$. These theories are a non-minimally coupled version of the recently constructed Generalized Quasitopological gravities and they satisfy a number of properties that we establish. We study magnetically-charged black hole solutions in these new theories and we find that for some of them the equations of motion can be fully integrated, enabling us to obtain analytic solutions. In those cases we show that, quite generally, the singularity at the core of the black hole is removed by the higher-derivative corrections and that the solution describes a globally regular geometry. In other cases, the equations are reduced to a second order equation for $f(r)$. Nevertheless, for all the theories it is possible to study the thermodynamic properties of charged black holes analytically. We show that the first law of thermodynamics holds exactly and that the Euclidean and Noether-charge methods provide equivalent results. We then study extremal black holes, focusing on the corrections to the extremal charge-to-mass ratio at a non-perturbative level. We observe that in some theories there are no extremal black holes below certain mass. We also show the existence of theories for which extremal black holes do not represent the minimal mass state for a given charge. The implications of these findings for the evaporation process of black holes are discussed.

description: The electron-positron annihilation spectrum observed by SPI/INTEGRAL during deep Galactic Center region exposure is reported. The line energy (510.954$\pm$0.075 keV) is consistent with the unshifted annihilation line. The width of the annihilation line is 2.37$\pm$0.25 keV (FWHM), while the strength of the ortho-positronium continuum suggests that the dominant fraction of positrons (94$\pm$6%) form positronium before annihilation. Compared to the previous missions these deep INTEGRAL observations provide the most stringent constraints on the line energy and width. Under the assumption of an annihilation in a single-phase medium these spectral parameters can be explained by a warm $T_e\sim 7000-4~10^4$ K gas with the degree of ionization larger than a few $10^{-2}$. One of the wide-spread ISM phases - warm ($T_e \sim 8000$ K) and weakly ionized (degree of ionization $\sim$ 0.1) medium satisfies these criteria. Other single-phase solutions are also formally allowed by the data (e.g. cold, but substantially ionized ISM), but such solutions are believed to be astrophysically unimportant. The observed spectrum can also be explained by the annihilation in a multi-phase ISM. The fraction of positrons annihilating in a very hot ($T_e \ge 10^6$ K) phase is constrained to be less than $\sim$8%. Neither a moderately hot ($T_e \ge 10^5$ K) ionized medium nor a very cold ($T_e \le 10^3$ K) neutral medium can make a dominant contribution to the observed annihilation spectrum. However, a combination of cold/neutral, warm/neutral and warm/ionized phases in comparable proportions could also be consistent with the data.

description: In recent years, thin-film organic field-effect transistors (OFETs) have begun to be considered as a possible alternative to the hydrogenated amorphous silicon thin-film transistors (a-Si:H TFT's) used in active matrix flat panel displays and other large-area electronics applications. Low-temperature processability, low-cost fabrication and compatibility with arbitrary substrates are some of the promising advantages of OFETs, among others. Of the many organic materials available, pentacene, in particular, is one of the leading candidates for use in current thin-film OFET architectures - this because of its excellent electrical characteristics and its resistance to atmospheric oxygen. In the recent literature, pentacene's transport properties, as well as transistor performance, have already been analyzed from the point of view of substrate treatments, pentacene evaporation rate and substrate temperature, electrode chemical nature and channel geometry. The results show that the morphology, crystal structure and molecular ordering of the first organic monolayer(s) at the pentacene/dielectric interface are essential determinants of carrier transport phenomena. To further investigate these interface effects, we have built a model organic field-effect transistor which consists essentially of a single layer of pentacene on an oxide substrate. Four-probe and two-probe transport measurements as a function of temperature and fields will be presented in relation with structural near-field observations. The experimental results suggest a simple two-dimensional model where the equilibrium between free and trapped carriers at the oxide interface determines the OFET characteristics and performance.

description: Diamond has attracted great interest as a quantum technology platform thanks to its optically active nitrogen vacancy center (NV). The NV's ground state spin can be read out optically exhibiting long spin coherence times of about 1 ms even at ambient temperatures. In addition, the energy levels of the NV are sensitive to external fields. These properties make NVs attractive as a scalable platform for efficient nanoscale resolution sensing based on electron spins and for quantum information systems. Diamond photonics enhances optical interaction with NVs, beneficial for both quantum sensing and information. Diamond is also compelling for microfluidic applications due to its outstanding biocompatibility, with sensing functionality provided by NVs. However, it remains a significant challenge to fabricate photonics, NVs and microfluidics in diamond. In this Report, an overview is provided of ion irradiation and femtosecond laser writing, two promising fabrication methods for diamond based quantum technological devices. The unique capabilities of both techniques are described, and the most important fabrication results of color center, optical waveguide and microfluidics in diamond are reported, with an emphasis on integrated devices aiming towards high performance quantum sensors and quantum information systems of tomorrow

description: We examine how the production of TeV scale black holes at colliders is influenced by the presence of Lovelock higher-curvature terms in the action of models with large extra dimensions. Such terms are expected to arise on rather general grounds, e.g., from string theory and are often used in the literature to model modifications to the Einstein-Hilbert action arising from quantum and/or stringy corrections. While adding the invariant which is quadratic in the curvature leads to quantitative modifications in black hole properties, cubic and higher invariants are found to produce significant qualitative changes, e.g., classically stable black holes. We use these higher-order curvature terms to construct a toy model of the black hole production cross section threshold. For reasonable parameter values we demonstrate that detailed measurements of the properties of black holes at future colliders will be highly sensitive to the presence of the Lovelock higher-order curvature terms.

Composite sol-gel alumina ceramic/siloxane coatings
Creators: name: Li, Gesheng
Publisher: name: University of British Columbia
Year: 2009

description: This thesis relates to the novel, relatively low temperature process (160-300°C) for preparation of chemically bonded composite sol-gel (CB-CSG) coatings. This "warm" temperature process (160-300°C) overcomes some drawbacks of the conventional composite sol-gel process, in particular minimization of stresses due to differential thermal expansion coefficient between the coating and the substrate. The biggest contribution o f this research involves use of siloxane bond coat between the CBCSG coating and the mild steel substrate, which relaxes residual stress in the coating, as well as protects the substrate from damage (corrosion) during the chemical bonding process. A method of multi-gun spraying to uniformly distribute the phosphates throughout the coating during the chemical bonding process is also an original contribution of this Thesis. The resulting coatings are free of surface cracks, have medium hardness (6.0GPa), moderate adhesion (42.0MPa) and good scratch resistance (17.0kgf). Electrochemical analysis shows that the multi-layer coating composed of the siloxane bond coat and the CB-CSG "top coat" forms a physical barrier against wet corrosion.

description: The multiple point principle (MPP), according to which several vacuum states with the same energy density exist, is put forward as a fine-tuning mechanism predicting the ratio between the fundamental and weak scales in the Standard Model (SM) and in its two Higgs doublet extension (2HDM). Using renormalization group equations for the SM, we obtain the effective potential in the 2-loop approximation and investigate the existence of its postulated second minimum at the fundamental scale. In the SM an exponentially huge ratio between the fundamental (Planck) and electroweak scales results: $\frac{Λ_{fund}}{Λ_{ew}} \sim e^{40}.$ But in the 2HDM the fundamental scale $Λ$ can vary from 10 TeV up to the Planck scale. Using the MPP, we predict the masses of the Higgs bosons.

description: Anisotropic materials, with orientation-dependent properties, have attracted more and more attention due to their compelling tunable and flexible performance in electronic and optomechanical devices. So far, two-dimensional (2D) black phosphorus shows the largest known anisotropic behavior, which is highly desired for synaptic and neuromorphic devices, multifunctional directional memories, and even polarization-sensitive photodetector, whereas it is unstable at ambient conditions. Recently, 2D few-layered As2S3 with superior chemical stability was successfully exfoliated in experiments. However, the electronic and mechanical properties of monolayer and bilayer As2S3 is still lacking. Here, we report the large anisotropic electronic and mechanical properties of As2S3 systems through first-principles calculations and general angle-dependent Hooke's law. Monolayer and bilayer As2S3 exhibit anisotropic factors of Young's modulus of 3.15 and 3.32, respectively, which are larger than the black phosphorous with experimentally confirmed and an anisotropic factor of 2. This study provides an effective route to flexible orientation-dependent nanoelectronics, nanomechanics, and offers implications in promoting related experimental investigations.

Subjects: Agricultural and Food Policy

description: This review paper attempts to bring together different issues in the light of recent developments in organic farming. The after effects of green revolution have encouraged the farmers to take up organic farming. This paper has reviewed the global and Indian scenario with reference to organic farming. In India, the cultivated land under certification is 2.8 Mha only. The key issues emerging in organic farming include yield reduction in conversion to organic farm, soil fertility enhancement, integration of livestock, certification constraints, ecology, marketing and policy support. The potential for organic farming, especially in the dryland regions has been discussed. It has been argued that organic farming is productive and sustainable, but there is a need for strong support to it in the form of subsidies, agricultural extension services and research.

description: Schiff moments were calculated for a set of nuclei with full account of core polarization effects. A finite range P and T violating weak nucleon-nucleon interaction has been used in the calculations. While in the absence of core polarization the Schiff moment depends on one combination of the weak interaction constants, in the presence of core polarization the Schiff moment depends on all three constants separately. The dominant contribution comes from isovector, $ΔT=1$, part of the weak interaction. The effects of core polarization were found to have in general a large effect on the Schiff moments.

Spectroscopic measurements show that these outflows have an enhanced elemental composition, which is a distinct signature of the slow wind. Current spectroscopic observations, however, do not have sufficient spatial resolution to distinguish what structures are being measured or to determine the driver of the outflows. The High-resolution Coronal Imager (Hi-C) flew on a sounding rocket in May, 2018, and observed areas of active region outflow at the highest spatial resolution ever achieved (250 km). Here we use the Hi-C data to disentangle the outflow composition signatures observed with the Hinode satellite during the flight. We show that there are two components to the outflow emission: a substantial contribution from expanded plasma that appears to have been expelled from closed loops in the active region core, and a second contribution from dynamic activity in active region plage, with a composition signature that reflects solar photospheric abundances. The two competing drivers of the outflows may explain the variable composition of the slow solar wind.

description: Seasonal migration of pastoral nomads, which constitutes a major proportion of human population in the Shivalik foothill villages in the Haryana state, is being practised since long in the region. To a large extent, these movements are associated with the absence of water resources development in the water-scarce regions. The present paper has examined the impact of watershed development programmes on seasonal livestock migration and has investigated the determinants of likelihood of such types of migration. The results have revealed that though the watershed development projects have helped in improving the productivity of agricultural land, the same gains are still to be realized on common lands because small and landless families entirely depend on common lands for livestock rearing. Evidence has shown that market access defines the degree of livestock exploitation and there is enormous scope for improving the effectiveness through focused interventions

description: The technical efficiency in crop production has been reported in different regions as well as in the state of Punjab to show how different regions have adopted the latest technology. Technical efficiency of individual farms has been estimated through stochastic frontier production function analysis. The production function estimates have pointed towards the presence of disguised unemployment in the sub-mountainous region of the Punjab state. The technical efficiency has shown a wide variation across regions. The average technical efficiency has been found maximum in the central region (90 per cent), followed by south-western and sub-mountainous regions. The main drivers of inefficiency have been identified as experience in agriculture and age of a farmer. The policy intervention to improve technical efficiency being not the same for all the regions, the study has observed that the state would benefit more if policy interventions are developed at the local level.

description: Possibility of description of the glass transition in terms of critical dynamics considering a hierarchy of the intermodal relaxation time is shown. The generalized Vogel-Fulcher law for the system relaxation time is derived in terms of this approach. It is shown that the system satisfies the fluctuating--dissipative theorem in case of the absence of the intermodal relaxation time hierarchy.

description: We present the calculation of the virtual corrections to gg→ZZ at next-to-leading order in QCD, focusing on the contribution from top quarks, which lacks a full analytic evaluation. The two-loop box diagrams are computed using a small-tansverse-momentum expansion, and the results are merged with those available in the high-energy expansion, in order to obtain an analytic description in the complete phase space.

description: The present investigation undertaken in the central Gujarat, has estimated the technical efficiency in rice production and has assessed the effect of farm-specific socio-economic factors on this technical efficiency. A stochastic frontier production function has been estimated to determine technical efficiency of individual farms and variance as well as regression analyses have been carried out to find the influence of socioeconomic factors. The study has revealed that the farm-specific technical efficiencies range from 71.39 per cent to 99.82 per cent, with the mean of 72.78 per cent, which indicates that on average, the realized output can be raised by 27 per cent in the region with the available technology and resources, without any additional resources. It has been found that factors like operational area, experience, education and distance of field from canal structure are the most influential determinants of technical efficiency, while the variable, number of working family members, has shown significant but negative relationship with technical efficiency. By adopting good management practices and proper allocation of the existing resources and technology, along with sound extension programmes, the potential that exists for improving the productivity of rice in the state, could be exploited.

description: The dust reverberation mapping is one of powerful methods to investigate the structure of the dusty tori in AGNs, and it has been performed on more than a hundred type 1 AGNs. However, no clear results have been reported on type 2 AGNs because their strong optical-UV extinction completely hides their accretion disc emission. Here we focus on an X-ray-bright type 2 AGN, NGC 2110, and utilize 2-20 keV X-ray variation monitored by MAXI to trace disc emission, instead of optical-UV variation. Comparing it with light curves in the WISE infrared (IR) W1 band ($λ= 3.4$ $μ$m) and W2 band ($λ= 4.6$ $μ$m) with cross-correlation analyses, we found candidates of the dust reverberation time lag at $\sim60$ days, $\sim130$ days, and $\sim1250$ days between the X-ray flux variation and those of the IR bands. By examining the best-fitting X-ray and IR light curves with the derived time lags, we found that the time lag of $\sim130$ days is most favoured. With this time lag, the relation between the time lag and luminosity of NGC 2110 is consistent with those in type 1 AGNs, suggesting that the dust reverberation in NGC 2110 mainly originates in hot dust in the torus innermost region, the same as in type 1 AGNs. As demonstrated by the present study, X-ray and IR simultaneous monitoring can be a promising tool to perform the dust reverberation mapping on type 2 AGNs.

description: The technical efficiency and factors affecting efficiency of wheat farmers under dryland and irrigated conditions in the Jammu district of J &K state have been reported for the year 2006. The stochastic frontier production function has been used to determine the technical efficiency of these farmers. Technical efficiency has been found different under both the conditions. The estimated mean technical efficiency of wheat farmers under dry condition has been found to be 0.84, indicating 84 per cent efficiency in their use of production inputs, and for irrigated condition it has been found to be 0.88, that means the average output of wheat could be increased by 12 per cent by adopting technology properly. The value of γ under dry and irrigated conditions has indicated that about 99 per cent and 88 per cent of the differences between the observed and the maximum production frontier outputs are due to the factors, which are under farmers’ control. The estimated value of λ under dry and irrigated conditions are significantly different from zero, indicating a good fit and the correctness of the distributional assumptions specified. The value of λ has been more than one, implying the dominance of one-sided component Ui in Ei and thus indicated high degree of technical inefficiency. In other words, the inefficiency component was not dominated by the random factors. The variance ratio γ has showed that the farm-specific variability contributed more to the variation in yield, which means that variation in output from frontier is attributed to technical inefficiency. Some of the factors found to influence the level of technical efficiency are higher level of education in irrigated condition and larger number of male workers under dry conditions.

description: Our nearest stellar neighbour, Proxima Centauri, is a low mass star with spectral typedM5.5 and hosting an Earth-like planet orbiting within its habitable zone. However, the habitability of the planet depends on the high-energy radiation of the chromo-spheric and coronal activity of the host star. We report the Astrosat, Chandra and HST observation of Proxima Centauri carried out as part of the multi-wavelength simultaneous observational campaign. Using the soft X-ray data, we probe the different activity states of the star. We investigate the coronal temperatures, emission measures and abundance. Finally, we compare our results with earlier observations of Proxima Centauri
