A Comparative Study on Payment Schemes For Watershed Services in New York City and Beijing
Creators: name: Lin, Fanyuan
Publisher: name: Consilience
Year: 2020

description: Payment for Ecosystem Services (PES), also known as Payment for Environmental Services, has become an increasingly popular economic approach to address environmental problems. The variety of ecosystem services, which are “components of nature, directly enjoyed, consumed or used to yield human well-being”, has rendered diversified PES programs targeting different ecological services. According to the United Nations Food and Agriculture Organization (FAO), watershed is among the services that are currently receiving most funds and interest worldwide. This article compares two distinctive watershed PES programs, namely the New York City Watershed Program and Beijing Watershed Program in China, and tries to discuss their different levels of success.

description: A structural transition at $T\approx 322$ K from the $Pmmm$ to $Pmma$ phase is found to coincide with an anomaly of resistivity. Another structural phase transition doubling the lattice parameter $c$, which has been postulated earlier to accompany a low-temperature magnetic transition in TbBaCo$_{2}$O$_{5.5}$, is observed in a single crystal DbBaCo$_{2}$O$_{5.5}$ by means of the X-ray and neutron diffraction. The low temperature phase does not belong to the space group $Pcca$ that has been chosen earlier as the highest subgroup of the $Pmma$. The transition is of the first order with the temperature hysteresis, between $T\approx 100$ and $T\approx 200$ K, which probably explains anomalous magnetic properties in this temperature range.

description: We present DES14X2fna, a high-luminosity, fast-declining type IIb supernova (SN IIb) at redshift $z=0.0453$, detected by the Dark Energy Survey (DES). DES14X2fna is an unusual member of its class, with a light curve showing a broad, luminous peak reaching $M_r\simeq-19.3$ mag 20 days after explosion. This object does not show a linear decline tail in the light curve until $\simeq$60 days after explosion, after which it declines very rapidly (4.38$\pm$0.10 mag 100 d$^{-1}$ in $r$-band). By fitting semi-analytic models to the photometry of DES14X2fna, we find that its light curve cannot be explained by a standard $^{56}$Ni decay model as this is unable to fit the peak and fast tail decline observed. Inclusion of either interaction with surrounding circumstellar material or a rapidly-rotating neutron star (magnetar) significantly increases the quality of the model fit. We also investigate the possibility for an object similar to DES14X2fna to act as a contaminant in photometric samples of SNe Ia for cosmology, finding that a similar simulated object is misclassified by a recurrent neural network (RNN)-based photometric classifier as a SN Ia in $\sim$1.1-2.4 per cent of cases in DES, depending on the probability threshold used for a positive classification.

Environmental Threats to the Symbiotic Relationship of Coral Reefs and Quorum Sensing
Creators: name: Generous, Rochanya A
Publisher: name: Consilience
Year: 2020

description: The coral reefs are declining in vitality and quantity in all parts of the world. Microbiomes exist symbiotically on the individual coral polyps. With this understanding comes the idea that microbiomes may coordinate survival through their inhabiting microbe colonies in order to sustain the life of the coral polyps. Of particular interest is quorum sensing, a form of bacterial communication known to coordinate gene expression in density dependent bacteria. The importance of understanding the symbiotic relationship between microbe’s use of quorum sensing and the coral it inhabits may offer insight in how microbiological colonies promote reef health and how external toxins alter these molecular processes.

description: A statistical approach based on the interval analysis (IA) is proposed for the analysis of the effects, on the radiation patterns radiated by phased arrays, of random errors and tolerances in the amplitudes and phases of the array-elements excitations. Starting from the efficient, reliable, and inclusive computation of the bounds of the complex-valued interval array pattern function by means of IA, an analytic method is presented to yield closed-form expressions for the probability of occurrence of a user-chosen value of the power pattern or of its features within the corresponding IA-derived bounds. A set of numerical examples is reported and discussed to assess the reliability of the proposed probabilistic interval analysis (PIA) method with the results from Monte Carlo simulations as well as to point out its effectiveness and potentialities/advantages/efficiency in real applications of great industrial interest.

description: The Pierre Auger Observatory has been designed to study the highest-energy cosmic rays in nature (E > 10^{18.5} eV). The determination of their arrival direction, energy and composition is performed by the analysis of the atmospheric showers they produce. The Auger Surface Array will consist of 1600 water Cerenkov detectors placed in an equilateral triangular grid of 1.5 km spacing. The aim of this paper is to show that the addition of a "small" area of surface detectors at half or less the above mentioned spacing would allow a dramatic increase of the physical scope of this Observatory, reaching lower energies at which the transition from galactic to extragalactic sources is expected.

Climate Change and Capitalism
Creators: name: Park, Jonathan T
Publisher: name: Consilience
Year: 2020

description: Capitalism was designed as a mechanism for efficiently allocating scarce resources, encouraging human ingenuity, and improving the quality of life for those willing and able to participate in the system. This economic model has been prodigiously effective at enabling people to convert natural resources into fungible commodities and monetary wealth. By transmuting vast amounts of natural resources into marketable products, capitalism has generated an unparalleled degree of wealth and prosperity. In theory, the production of wealth and the collective quality of life can be constantly enhanced under this economic model. Although wealth accumulation has hitherto entailed the unsustainable depletion of natural resources, capitalism maintains that when a commercially viable resource is exhausted, the market will produce an alternative. Thus, capitalism is supposedly an indefatigable method for perpetually generating more wealth and greater social prosperity.

The Chevreton Tensor and Einstein-Maxwell Spacetimes Conformal to Einstein Spaces

Year: 2007
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In this paper we characterize the source-free Einstein-Maxwell spacetimes which have a trace-free Chevreton tensor. We show that this is equivalent to the Chevreton tensor being of pure-radiation type and that it restricts the spacetimes to Petrov types \textbf{N} or \textbf{O}. We prove that the trace of the Chevreton tensor is related to the Bach tensor and use this to find all Einstein-Maxwell spacetimes with a zero cosmological constant that have a vanishing Bach tensor. Among these spacetimes we then look for those which are conformal to Einstein spaces. We find that the electromagnetic field and the Weyl tensor must be aligned, and in the case that the electromagnetic field is null, the spacetime must be conformally Ricci-flat and all such solutions are known. In the non-null case, since the general solution is not known on closed form, we settle with giving the integrability conditions in the general case, but we do give new explicit examples of Einstein-Maxwell spacetimes that are conformal to Einstein spaces, and we also find examples where the vanishing of the Bach tensor does not imply that the spacetime is conformal to a $C$-space. The non-aligned Einstein-Maxwell spacetimes with vanishing Bach tensor are conformally $C$-spaces, but none of them are conformal to Einstein spaces.

Study of OSI protocol processing engines
Creators: name: Takeuchi, Leonard Yasuhiko
Publisher: name: University of British Columbia
Year: 2010

description: The increases in communication bandwidth provided by fiber optics and high-speed switching technologies have shifted the limiting factor in data throughput from the communication link to the communication processing. The communication processing for open systems interconnection (OSI) in particular is quite heavy due to the inclusion of data transfer syntax conversion in order to assure interoperability between different machine types. In this thesis report, two multiprocessing architectures are considered as protocol processing engines for OSI communications. The conventional approach is to have the host computer perform the protocol processing especially for the higher layers. However, the protocol processing burden at communication rates of hundreds or even thousands of million bits per second places such a heavy processing burden on the host that this becomes undesirable. The protocol processing engines act as front-end systems performing most of the OSI protocol processing, including the transfer syntax conversion, on behalf of the host. A multiprocessor approach was selected because the required amount of processing power can be supplied using lower processor technology than for an uniprocessor approach. The protocol engines were designed based on a processing model in which different packets are processed at the same time in different processors. The protocol engines are designed to perform the protocol processing for OSI layers 2 through 6. Results obtained from simulating the designs indicate that a processing throughput of a hundred megabit per second is achievable only for packets which contain very simple data structures.

Year: 2020

description: Despite the great awareness on the health and environmental implications of poorly disposed wastewater, the continuous pollution of the environment and surface water with wastewater generated from domestic, institutional and industrial activities in many Nigerian cities still remains a major concern. As population grows with rising standard of living more wastewater is generated and disposed to sensitive environments with negative impacts on the human and ecosystems. To promote sustainable and efficient wastewater management, global attention must be drawn towards wastewater reuse for both potable and non-potable uses. This paper presents baseline information on global wastewater reuse that can serve as a valuable guide on the integration of wastewater reuse in Nigeria as a component of National Integrated Water Resources Management.

description: The explosion of a carbon-oxygen white dwarf as a Type Ia supernova is known to be sensitive to the manner in which the burning is ignited. Studies of the pre-supernova evolution suggest asymmetric, off-center ignition, and here we explore its consequences in two- and three-dimensional simulations. Compared with centrally ignited models, one-sided ignitions initially burn less and release less energy. For the distributions of ignition points studied, ignition within two hemispheres typically leads to the unbinding of the white dwarf, while ignition within a small fraction of one hemisphere does not. We also examine the spreading of the blast over the surface of the white dwarf that occurs as the first plumes of burning erupt from the star. In particular, our studies test whether the collision of strong compressional waves can trigger a detonation on the far side of the star as has been suggested by Plewa et al. (2004). The maximum temperature reached in these collisions is sensitive to how much burning and expansion has already gone on, and to the dimensionality of the calculation. Though detonations are sometimes observed in 2D models, none ever happens in the corresponding 3D calculations. Collisions between the expansion fronts of multiple bubbles also seem, in the usual case, unable to ignite a detonation. "Gravitationally confined detonation" is therefore not a robust mechanism for the explosion. Detonation may still be possible in these models however, either following a pulsation or by spontaneous detonation if the turbulent energy is high enough.

The Longevity of the Magnet Effect: Fire-Herbivory Interactions in Central Kenya
Creators: name: Bernard, Miranda
name: Menz, Alyssa

Publisher: name: Consilience
Year: 2020

description: The coexistence of grass and trees that typifies savanna ecosystems is maintained in part by top-down forces including herbivory and fire. Understanding fire-herbivore interactions is an integral step in determining the effect of these forces individually and informs decisions about the use of fire as a livestock management technique. The magnet effect, in which grazers are drawn to an area after it is burned, is one such interaction between fire and herbivores. While the process of the magnet effect has been described, neither its longevity nor the manner through which fire intensity affects its strength is understood. In this study, we explored whether the increase in herbivory pressure predicted by the magnet effect is maintained over long periods after a fire, how fire intensity influences the strength of the magnet effect, and which feeder types are most influenced by the magnet effect. We established five field sites at the Mpala Research Centre in Laikipia, Kenya that ranged in fire intensity and elapsed time since last the burn. We found that the magnet effect is transient on a seven-year scale and affects grazers more than browsers or mixed feeders, though herbivory and grass biomass responses to fire intensity were conflicting. This research clarifies the role of the magnet effect in maintaining savanna ecosystems and can aid agriculturalists seeking to use fire as a management technique by indicating how long after a burn increased palatability of grass can be expected.

description: The design of phased arrays able to generate arbitrary-shaped beams through a sub-arrayed architecture is addressed here. The synthesis problem is cast in the excitation matching framework, so as to yield clustered phased arrays providing optimal trade-offs between the complexity of the array architecture (i.e., the minimum number of control points at the sub-array level) and the matching of a reference pattern. A synthesis tool based on the k-means algorithm is proposed for jointly optimizing the sub-array configuration and the complex sub-array coefficients. Selected numerical results, including pencil beams with sidelobe notches and asymmetric lobes as well as shaped main lobes, are reported and discussed to highlight the peculiarities of the proposed approach also in comparison with some extensions to complex excitations of state-of-the-art sub-array design methods.

description: We summarize researches - in great deal jointly with my host Y. Sarantopoulos and his PhD. students V. Anagnostopoulos and A. Pappas - started by a Marie Curie fellowship in 2001 and is still continuing. The project was to study multivariate polynomial inequalities. In the course of work we realized the role of the ``generalized Minkowski functional'', to which we devoted a throughout survey. Resulting from this, infinite dimensional extensions of Chebyshev's extremal problems were tackled successfully. Investigating Bernstein-Markov constants for homogeneous polynomials of real normed spaces led us to the application of potential theory. Also we found at first unexpected connections of polarization constants of R^2 and C^2 to Chebyshev constants of S^2 and S^3, respectively. In the study of polarization constants, a further application of potential theory occurred. This led us to realize that the theory of rendezvous numbers can be much better explained by potential theory, too. Our methods for obtaining Bernstein type pointwise gradient estimates for polynomials were compared in a recent case study to the yields of pluripotential theoretic methods. The findings were that the two rather different methods give exactly the same results, but the two currently standing conjectures mutually exclude each other.
Gentrifying a Superfund Site: Why Gowanus, Brooklyn is Becoming a Real Estate Hot Spot
Creators: name: Krisel, Rebecca Salima
Publisher: name: Consilience
Year: 2020

description: This feature length article tells the story of Gowanus, a Brooklyn neighborhood on the Gowanus Canal, haunted by the pollutants of its industrial past. that rests along the banks of the Gowanus Canal. The Environmental Protection Agency recognized the latter Gowanus Canal as a Superfund cleanup site in March 2010. Yet , Gowanus is experiencing an economic and cultural revival. What was historically a booming manufacturing area with active warehouses spilling their waste into the Gowanus Canal is now an industrial wasteland site where middle to upper class families, seeking to purchase organic foods, are willing to relocate and settle down. As of December 2014, a two-bedroom condo boasting waterfront views and located just one block away from the Gowanus Canal on Carroll Street in between Nevins Street and Third Avenue, was selling priced atfor $1,549,000. The average price per square foot for homes in Gowanus is 50 percent higher than the rest of Brooklyn. This story links issues of sustainable development and current urban housing needs in New York City. My research rested primarily on interviews with subjects who have specific expertise in the changes of the neighborhood. I was fortunate to speak with a real estate agent who specializes in Gowanus, a representative at an affordable housing advocacy group working on development in Gowanus, two separate families who moved to the area when they started began having children, and a life-long resident of 27 years. I also attended two community meetings relating to the sustainable development of Gowanus in addition to speaking with some old and new shop dwellers.

A theory of gravity as a pressure force. II. Lorentz contraction and "relativistic" effects
Creators: name: Arminjon, Mayeul
Publisher: name: arXiv
Year: 2006
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: In a foregoing paper, gravity has been interpreted as the pressure force exerted on matter at the scale of elementary particles by a perfect fluid. Under the condition that Newtonian gravity must be recovered in the incompressible case, a scalar field equation has thus been proposed for gravity, giving a new theory in the compressible case. Here the theory is reinterpreted so as to describe the relativistic effects, by extending the Lorentz-Poincaré interpretation of special relativity which is first recalled. Gravitational space-contraction and time-dilatation are postulated, as a consequence of the principle of local equivalence between the effects of motion and gravitation. The space-time metric (expressing the proper time along a trajectory) is hence curved also in the proposed theory. As the result of a modified Newton law, it is proved that free test particles follow geodesic lines of this metric. In the spherical static situation, Schwarzschild's exterior metric is exactly recovered and with it the experimental support of general relativity, but the interior solution as well as the problematic of singularities are different in the proposed theory, e.g. the radius of the body cannot be smaller than the Schwarzschild radius.

Technical Efficiency-Food Security Nexus in Kaduna State, Nigeria: A Case Study of Poultry Egg Farmers
Creators: name: Oyakhilomen, Oyinbo
Publisher: name: Consilience
Year: 2020

description: This study analysed the technical efficiency of poultry egg production for sustainable food security in the study area using primary data. The data were analysed using stochastic frontier, the US Department of Agriculture (USDA) food security measurement, and correlation analysis to determine the relationship between technical efficiency and food security. The result of the study revealed that the poultry egg farmers had a very low technical efficiency of 23%, which implies that the poultry egg farmers have a chance of improving their technical efficiency by 77% using their available resource efficiently. The result also revealed that few of the households (10%) were food secure while most of them (90%) were food insecure at different levels of food insecurity. The result of the study further indicated a direct relationship between technical efficiency and food security at 1% level of probability, implying that as average productivity increases, food security increases. The policy implication is that food security among the poultry egg farmers is linked with improving their farm efficiency. If food security is to be ensured among the poultry egg farmers, their farming activities must be efficient. The study recommended that the poor food security status of the poultry egg farmers be improved by addressing their low level of technical efficiency through ensuring the efficient utilization of their available resources. This calls for emphasis on extension activities to focus on training poultry egg farmers on improved production management practices.

description: Stress-induced martensitic transformations enable metastable alloys to exhibit enhanced strain hardening capacity, leading to improved formability and toughness. As is well-known from transformation-induced plasticity (TRIP) steels, however, the resulting martensite can limit ductility and fatigue life due to its intrinsic brittleness. In this work, we explore an alloy design strategy that utilizes stress-induced martensitic transformations but does not retain the martensite phase. This strategy is based on the introduction of superelastic nano-precipitates, which exhibit reverse transformation after initial stress-induced forward transformation. To this end, utilizing ab-initio simulations and thermodynamic calculations we designed and produced a V45Ti30Ni25 (at%) alloy. In this alloy, TiNi is present as nano-precipitates uniformly distributed within a ductile V-rich base-centered cubic (bcc) beta matrix, as well as being present as a larger matrix phase. We characterized the microstructure of the produced alloy using various scanning electron microscopy (SEM) and transmission electron microscopy (TEM) methods. The bulk mechanical properties of the alloy are demonstrated through tensile tests, and the reversible transformation in each of the TiNi morphologies were confirmed by in-situ TEM micro-pillar compression experiments, in-situ high-energy diffraction synchrotron cyclic tensile tests, indentation experiments, and differential scanning calorimetry experiments. The observed transformation pathways and variables impacting phase stability are critically discussed

description: The spatial coherence of an atomic wavepacket can be detected in the scattered photons, even when the center-of-mass motion is in the quantum coherent superposition of two distant, non-overlapping wave packets. Spatial coherence manifests itself in the power spectrum of the emitted photons, whose spectral components can exhibit interference fringes as a function of the emission angle. The contrast and the phase of this interference pattern provide information about the quantum state of the center of mass of the scattering atom.

Scale effects of freeing ports
Creators: name: Williamson, Peter Bruce
Publisher: name: University of British Columbia
Year: 2010

description: Freeing ports are found on almost all ships and their ability to drain water from the deck of a ship in rough weather can be critical to both the ship and crews' survival. At present, tests of freeing port performance on models may not be performed due to the effects of viscosity and surface tension that arise due to the decreased scale. In this thesis, the effect of scaling down freeing ports to a model size is examined, and a method of testing freeing ports on models is proposed that would incorporate the monitoring of water on the deck of the model and a control algorithm that would control the discharge from the model. To examine the effect of scale on freeing port discharge, discharge through twelve different sizes of long narrow slots ranging from 1 to 15 millimetres high are tested. Comparisons are made between the cases of steady state discharge, with a constant head, unsteady discharge, with a declining head, and unsteady discharge with the test vessel rocking to generate the sloshing motion of the water that one would expect to find on the deck of a ship in rough seas. It is found that while larger holes drain water off at the rate that one would expect at full scale, the smaller holes can let off either too much water or too little water, depending on the relative water depth. For this reason, it appears that an active system is needed to be able to test freeing port performance successfully on models.

description: The BioReCer interview series showcases the different work packages and tasks within the BioReCer project in its quest to develop guidelines and recommendations for the certification of biobased feedstocks. 

This issue presents Ángel Adell from Euradia/Betania who will elaborates on IP management and DEC in European projects and especially BioReCer.

BioReCer (Biological Resources Certifications Schemes) aims at assessing and complementing current certification schemes for biological resources according to the new EU sustainability goals to enhance bio-based circular systems.

This will be achieved by including new criteria that align with EU taxonomy and EU corporate due diligence regulations into guidelines for certifying biological resources’ sustainability, origin, tracking and traceability (T&T), and by ensuring applicability at EU and global scale.

By promoting the sustainability and trade of biological resources, BioReCer will increase the added value, use, as well as social acceptance of bio-based products.

description: We investigate the interplay of the topological and Kondo effects in a one-dimensional Kondo-Heisenberg model with nontrivial conduction band using the density matrix renormalization group method. By analyzing the density profile, the local hybridization, and the spin/charge gap, we find that the Kondo effect can be destructed at the edges of the chain by the topological end state below a finite critical Kondo coupling $J_{K}^{c}$. We construct a phase diagram characterizing the transition of the end states.

description: This study compares the incomes generated from periwinkle and dog-winkle catch amongst farmers in oil spill- affected and non-oil -spill-affected areas in Gokana and Khana Local Government Areas, Rivers State, Nigeria. A total of 120 farmers were randomly selected and data were collected using structured questionnaires and personal interviews. Analytical tools used included descriptive statistics, net income model, T- test and regression analysis model. Results indicated that income realized by the farmers from shellfish sales in non-oil spill-affected Local Government was higher than that of the oil spill-affected Local Government Area per annum and was estimated as ₦407,812.79.00 and ₦182,485.00 respectively. The level of profit recorded among the farmers in the two areas was significantly different with a T-value of 14.42. The null hypothesis was rejected. The regression model employed three functional forms; linear, semi log and double log. Linear model was chosen as the lead equation because of the highest R2 of 59%. Cost of labor and transportation had significant effect on the level of profit. Cost of labor positively influenced profit while cost of transportation negatively influenced the profit. It is recommended that government intervention programs provide a cheaper means of transportation in the area.

description: We have probed the Landau levels of nodal quasi-particles by tunneling along a nodal direction of (110) oriented YBa$_2$Cu$_3$O$_{7-x}$ thin films with a magnetic field applied perpendicular to the $CuO_2$ planes, and parallel to the film's surface. In optimally doped films and at low temperature, finite energy nodal states are clearly observed in films thinner than the London penetration depth. Above a well defined temperature the order parameter reverts to a pure \emph{d}-wave symmetry.

description: The design of isophoric phased arrays composed of two-sized square-shaped tiles that fully cover rectangular apertures is dealt with. The number and the positions of the tiles within the array aperture are optimized to fit desired specifications on the power pattern features. Toward this end, starting from the derivation of theoretical conditions for the complete tileability of the aperture, an ad hoc coding of the admissible arrangements, which implies a drastic reduction of the cardinality of the solution space, and their compact representation with a graph are exploited to profitably apply an effective optimizer based on an integer-coded genetic algorithm. A set of representative numerical examples, concerned with state-of-the-art benchmark problems, is reported and discussed to give some insights on the effectiveness of both the proposed tiled architectures and the synthesis strategy.
Hamiltonian charges in the asymptotically de Sitter spacetimes

description: We generalize a notion of 'conserved' charges given by Wald and Zoupas to the asymptotically de Sitter spacetimes. Surprisingly, our construction is less ambiguous than the one encountered in the asymptotically flat context. An expansion around exact solutions possessing Killing vectors provides their physical meaning. In particular, we discuss a question of how to define energy and angular momenta of gravitational waves propagating on Kottler and Carter backgrounds. We show that obtained expressions have a correct limit as $Λ\to 0$. We also comment on the relation between this approach and the one based on the canonical phase space of initial data at $\mathcal{I}^+$.

description: The quality of rainwater, which is the main source of domestic water in Dzodze, a community in the Volta Region of Ghana, was unknown. Therefore, the possible utilization of contaminated domestic water and occurrence of health hazards could not be underestimated due to prevailing poor hygiene and a great lack of standard maintenance and treatment systems in the community. In this study, we assessed the quality of rainwater in the Dzodze Community community and how it varies along the DRWH[BH1] chain from free-fall to storage. Rain samples were collected at three points along the domestic rainwater harvesting (DRWH) chain. Specifically, the three points from were free-fall, roof-catchmentroof catchment, and storage tank, and the two systems were “described as poorly-maintained” and “well-maintained” systems. The physico-chemical and bacteriological patterns of rainwater samples were analyzed for physico-chemical and bacteriological parameters and results were compared with World Health Organization (and Ghana Standards Board guideline values. The harvested rainwater was found to be of good physico-chemical quality, but not bacteriological, quality but not bacteriological, calling for treatment before utilization. Also, irrespective of the type of DRWH system (poorly-maintained or well-maintained), there were substantial changes in rainwater quality upon interaction with roof-catchmentroof catchment, with an increase noticed in all parameters.
