description: The study investigated costs and returns of provitamin A cassava production among smallholder farmers in Delta State, Nigeria. By implementing bio-fortification, the prevalence of vitamin A deficiency can be reduced, considering the important role of pro-vitamin A cassava in the diets of rural households in Nigeria. Multistage, purposive, and simple random sampling techniques were used to select 120 respondents for the study. Structured questionnaires were used to collect data. Descriptive statistics and net farm incomes were used in analyzing the data. Results revealed that the majorities (62.5%) were females, 45.8% were within the age range of 31 years and 40 years, 37.0% were married, 41.7% had 31-40 years of farming experience, and the majority (50.0%) of the respondents had secondary school education. Out of the 15 variables investigated as regards the determinants of cassava production in Delta State, only six (6) variables were found to be statistically related to the factors influencing the determinants of cassava production in the study area. Those variables were family size, farming experience, annual income, educational level, farm size, and age. The enterprise was profitable based on the positive values of gross margin (₦3,602,575), net farm income (₦2,804,675), and net return on investment (₦1.53k). This implies that yam production is a profitable enterprise in the study area since RNI was greater than one. The constraints were: high cost of labor, pests/disease attack, low knowledge of improved yam, poor extension services, inadequate finance, poor road network, and high cost of local seed. Therefore, it is recommended that farmers should be encouraged to join cooperative society in order to pool their resources together to take advantage of economies of scale, especially in the purchase of inputs, thereby reducing the cost of production.

When the past becomes present : storytelling, postcolonial autoethnography, and Asian Canadian studies
Creators: name: Diehl, Lindsay Ann
Publisher: name: University of British Columbia
Year: 2018

description: This creative-critical dissertation brings the family stories of the researcher’s Chinese Canadian grandmother into dialogue with a canon of Chinese Canadian narratives. Whereas the familial stories trace a matrilineal history that begins with immigration from China to Canada in 1874, the analysis of Chinese Canadian narratives investigates how this canon has been imagined and produced. In juxtaposing these creative and critical interests, this dissertation explores the tension between the creative impulse to (re)articulate experiences and the critical awareness that conventional narrative forms can be restrictive. The aim of the dissertation is to highlight the importance of sharing the stories of previous generations, while also uncovering some of the potential difficulties and pitfalls of such an endeavour. In paying heed to the dialectic relationship between past and present Chinese Canadian writing, the dissertation engages with an emergent critique of the formation of Asian Canadian literature. Whereas some critics have discussed Asian Canadian literature as a “coming to voice” of previously silenced groups in Canada, others have warned of the dangers of producing Asian Canadian subjects as mimetic of mainstream subjects. In light of these debates, this research project asks: What are the limitations of historical fiction and life-writing genres? How do narratives of progress or national belonging continue to shape racial injustice in Canada? And how can anti-racist efforts allow for new possible coalitions and better account for differences in situation, experience, and privilege? Drawing on postcolonial studies and transnational feminist theory, and rooted in the concept of postcolonial autoethnography, the project foregrounds the researcher’s contradictory subject positioning, produced through the privilege and alterity of being a third-generation Canadian-born woman of mixed Chinese and European descent. As a creative-critical project, it moves away from disinterested objectivity, reflecting upon and participating in the production of literary accounts while committing to anti-colonial, anti-racist scholarship and praxis, as well as to innovative ideas of responsibility, engagement, and solidarity.

A Constraint on the Organization of the Galactic Center Magnetic Field Using Faraday Rotation

description: We present new 6 and 20 cm Very Large Array (VLA) observations of polarized continuum emission of roughly 0.5 square degrees of the Galactic center (GC) region. The 6 cm observations detect diffuse linearly-polarized emission throughout the region with a brightness of roughly 1 mJy per 15"x10" beam. The Faraday rotation measure (RM) toward this polarized emission has structure on degree size scales and ranges from roughly +330 rad/m2 east of the dynamical center (Sgr A) to -880 rad/m2 west of the dynamical center. This RM structure is also seen toward several nonthermal radio filaments, which implies that they have a similar magnetic field orientation and constrains models for their origin. Modeling shows that the RM and its change with Galactic longitude are best explained by the high electron density and strong magnetic field of the GC region. Considering the emissivity of the GC plasma shows that while the absolute RM values are indirect measures of the GC magnetic field, the RM longitude structure directly traces the magnetic field in the central kiloparsec of the Galaxy. Combining this result with previous work reveals a larger RM structure covering the central ~2 degrees of the Galaxy. This RM structure is similar to that proposed by Novak and coworkers, but is shifted roughly 50 pc west of the dynamical center of the Galaxy. If this RM structure originates in the GC region, it shows that the GC magnetic field is organized on ~300 pc size scales. The pattern is consistent with a predominantly poloidal field geometry, pointing from south to north, that is perturbed by the motion of gas in the Galactic disk.

description: We present a detailed light curve analysis of publicly available V band observations of 62 binary stars, mostly contact binaries, obtained by the All Sky Automated Survey (ASAS)-3 project between 2000 and 2009. Eclipsing binaries are important astronomical targets for determining the physical parameters of component stars from the geometry. They provide an independent direct method of measuring the radii of stars. We improved the ASAS determined periods, ephemeris and obtained the Fourier parameters from the phased light curves of these 62 stars. These Fourier parameters were used for preliminary classification of the stars in our sample. The phased light curves were then analysed with the aid of the Wilson-Devinney light curve modelling technique in order to obtain various geometrical and physical parameters of these binaries. The spectroscopic mass ratios as determined from the the radial velocity measurements available in the literature were used as one of the inputs to the light curve modelling. Thus reliable estimations of parameters of these binaries were obtained with combined photometric and spectroscopic data and error estimates were made using the heuristic scan method.

description: Over the last few years several models have been proposed to interpret the widespread soft excess observed in the X-ray spectra of type 1 active galactic nuclei (AGN). In particular, reflection from the photoionized accretion disc blurred by relativistic effects has proven to be successful in reproducing both the spectral shape and the variability pattern of many sources. As a further test to this scenario we present the analysis of a recent ~100 ks long Suzaku observation of Arakelian 120, a prototypical 'bare' Seyfert 1 galaxy in which no complex absorption system is expected to mimic a soft excess or mask the intrinsic properties of this key component. We show that a reflection model allowing for both warm/blurred and cold/distant reprocessing provides a self-consistent and convincing interpretation of the broadband X-ray emission of Ark 120, also characterized by a structured iron feature and a high-energy hump. Although warm absorbers, winds/outflows and multiple Comptonizing regions may play significant roles in sources with more spectral complexity, this case study adds evidence to the presence of blurred disc reflection as a basic component of the X-ray spectra of type 1 AGN.

description: Superconductivity in layered copper-oxide compounds emerges when charge carriers are added to antiferromagnetically-ordered CuO2 layers. The carriers destroy the antiferromagnetic order, but strong spin fluctuations persist throughout the superconducting phase and are intimately linked to super-conductivity. Neutron scattering measurements of spin fluctuations in hole-doped copper oxides have revealed an unusual `hour-glass' feature in the momentum-resolved magnetic spectrum, present in a wide range of superconducting and non-superconducting materials. There is no widely-accepted explanation for this feature. One possibility is that it derives from a pattern of alternating spin and charge stripes, an idea supported by measurements on stripe-ordered La1.875Ba0.125CuO4. However, many copper oxides without stripe order also exhibit an hour-glass spectrum$. Here we report the observation of an hour-glass magnetic spectrum in a hole-doped antiferromagnet from outside the family of superconducting copper oxides. Our system has stripe correlations and is an insulator, which means its magnetic dynamics can conclusively be ascribed to stripes. The results provide compelling evidence that the hour-glass spectrum in the copper-oxide superconductors arises from fluctuating stripes.

description: With the increasing size and frequency of mass events, the study of crowd disasters and the simulation of pedestrian flows have become important research areas. Yet, even successful modeling approaches such as those inspired by Newtonian force models are still not fully consistent with empirical observations and are sometimes hard to calibrate. Here, a novel cognitive science approach is proposed, which is based on behavioral heuristics. We suggest that, guided by visual information, namely the distance of obstructions in candidate lines of sight, pedestrians apply two simple cognitive procedures to adapt their walking speeds and directions. While simpler than previous approaches, this model predicts individual trajectories and collective patterns of motion in good quantitative agreement with a large variety of empirical and experimental data. This includes the emergence of self-organization phenomena, such as the spontaneous formation of unidirectional lanes or stop-and-go waves. Moreover, the combination of pedestrian heuristics with body collisions generates crowd turbulence at extreme densities-a phenomenon that has been observed during recent crowd disasters. By proposing an integrated treatment of simultaneous interactions between multiple individuals, our approach overcomes limitations of current physics-inspired pair interaction models. Understanding crowd dynamics through cognitive heuristics is therefore not only crucial for a better preparation of safe mass events. It also clears the way for a more realistic modeling of collective social behaviors, in particular of human crowds and biological swarms. Furthermore, our behavioral heuristics may serve to improve the navigation of autonomous robots.

description: Complex sequencing rules observed in birdsongs provide an opportunity to investigate the neural mechanism for generating complex sequential behaviors. To relate the findings from studying birdsongs to other sequential behaviors, it is crucial to characterize the statistical properties of the sequencing rules in birdsongs. However, the properties of the sequencing rules in birdsongs have not yet been fully addressed. In this study, we investigate the statistical propertiesof the complex birdsong of the Bengalese finch (Lonchura striata var. domestica). Based on manual-annotated syllable sequences, we first show that there are significant higher-order context dependencies in Bengalese finch songs, that is, which syllable appears next depends on more than one previous syllable. This property is shared with other complex sequential behaviors. We then analyze acoustic features of the song and show that higher-order context dependencies can be explained using first-order hidden state transition dynamics with redundant hidden states. This model corresponds to hidden Markov models (HMMs), well known statistical models with a large range of application for time series modeling. The song annotation with these models with first-order hidden state dynamics agreed well with manual annotation, the score was comparable to that of a second-order HMM, and surpassed the zeroth-order model (the Gaussian mixture model (GMM)), which does not use context information. Our results imply that the hierarchical representation with hidden state dynamics may underlie the neural implementation for generating complex sequences with higher-order dependencies.
Rural religion at rock sanctuaries in Roman Spain : an alternative model
Creators: name: McCullough, Kimberly
Publisher: name: University of British Columbia
Year: 2018

description: Rural religion in Roman Spain continues to be misunderstood due to problematic narratives in both ancient and modern sources. In the age of Augustus, the Greek geographer Strabo put forth misrepresentations of the religious beliefs and practices of inhabitants of Hispania as a result of two main problems, the polis-religion model view and idea of acculturation. Strabo and his sources’ shared a lack of familiarity with religious expressions in the rural sphere of Roman Spain due to their narrow view of religious rites. Moreover, writers under the Roman Empire like Strabo tend to emphasize cultural transformations to the “Roman mode of life” as positive and widespread experiences, even if in reality the process was much more gradual and varied. This Strabonian meta-narrative problematizes our understanding of religious change in the region of Hispania. What’s more, this meta-narrative has lived on in modern scholarship as scholars continue to focus their inquiries into religious change largely on the urban centers of society, conceptualize religious and cultural change in terms of acculturation models such as “Romanization,” and treat religious beliefs in isolation from practice by ignoring the spatial context of epigraphic evidence. In response to such problematic frameworks, I propose an alternative model aimed at presenting a more complete picture of religion in Roman Spain. Throughout this framework, I privilege the study of the rural sphere, trace instances of inventing traditions in rural religion, and analyze the epigraphic evidence alongside its spatial context in order to look beyond the narrow range of material covered by past scholars. In the first chapter I apply my alternative model to the sanctuary of Panóias and demonstrate the inability of past approaches to portraying the innovative agency taking place. In the second chapter I test the applicability of interpretations of Panóias to other rock sites in Spain as done by past scholars. I conclude that Panóias is not necessarily applicable as a model to other sites, although interpretations made through the application of an alternative model does drive knowledge forward by helping us understanding individual agency and the invention of tradition in rural religion in Roman Spain.

 Notes. These specimens are similar to Didymium decipiens Meyl., with the capillitium tubules twisted like a spiral. However, the spore ornamentation consists of unevenly distributed warts with a paler area. In comparison, the original description of the species reported prominent warts connected by fine lines lacking a paler area. Poulain et al. (2011) referred to the taxon Didymium pseudodecipiens ad int., with the capillitium tubules also bearing spirals but with the spores ornamented with thick spinules.

description: The Moderate Resolution Imaging Spectroradiometer (MODIS) level-3 chlorophyll-a (Chl-a) product is one of the widely used ocean colour products that is often used for water quality monitoring of marine ecosystems. However, this product includes a large amount of missing data due to high surface reflectance and cloudy conditions that inevitably affect its suitability for spatiotemporal analysis of water quality. The objective of this study was to compare four Machine Learning (ML) techniques including K-nearest neighbour (KNN), Support Vector Regression (SVR), Random Forest Regression (RFR), and Artificial Neural Network (ANN) with well-known Data Interpolation Empirical Orthogonal Function (DINEOF) method for spatiotemporal missing imputation of MODIS Chl-a. The Southern Caspian Sea, which has a high Chl-a concentration, was selected as the case study. A cross-validation approach ranging missing data ratio from 0.1 to 0.8 was implemented to investigate the optimal parameters of the models and compare their performance for missing imputation. The results indicated that all ML models, except KNN, outperformed the DINEOF method for missing imputation of MODIS Chl-a. The SVR with the highest accuracy and the lowest variability of errors had the best performance among the five competing models, while the KNN showed the worst performance. The main reason for the better accuracy of the SVR than the other models is its structural risk minimization procedure that leads to the better generalization of the SVR model. The current results showed that the ML techniques used in the current study, the SVR in particular, are able to produce reliable imputations of the MODIS Chl-a missing data and can be a useful tool in water quality monitoring of marine ecosystems.

description: We conducted a number of multi-band coronagraph experiments using a vacuum chamber and a binary-shaped pupil mask which in principle should work at all wavelengths, in the context of the research and development on a coronagraph to observe extra-solar planets (exoplanets) directly. The aim of this work is to demonstrate that subtraction of Point Spread Function (PSF) and multi-band experiments using a binary-shaped pupil mask coronagraph would help improve the contrast in the observation of exoplanets. A checkerboard mask, a kind of binary-shaped pupil mask, was used. We improved the temperature stability by installing the coronagraph optics in a vacuum chamber, controlling the temperature of the optical bench, and covering the vacuum chamber with thermal insulation layers. We evaluated how much the PSF subtraction contributes to the high contrast observation by subtracting the images obtained through the coronagraph. We also carried out multi- band experiments in order to demonstrate a more realistic observation using Super luminescent Light Emitting Diodes (SLEDs) with center wavelengths of 650nm, 750nm, 800nm and 850nm. A contrast of 2.3x10-7 was obtained for the raw coronagraphic image and a contrast of 1.3x10-9 was achieved after PSF subtraction with a He-Ne laser at 632.8nm wavelength. Thus, the contrast was improved by around two orders of magnitude from the raw contrast by subtracting the PSF. We achieved contrasts of 3.1x10-7, 1.1x10-6, 1.6x10-6 and 2.5x10-6 at the bands of 650nm, 750nm, 800nm and 850nm, respectively, in the multi-band experiments. The results show that contrast within each of the wavelength bands was significantly improved compared with non-coronagraphic optics. We demonstrated PSF subtraction is potentially beneficial for improving contrast of the coronagraph, and this coronagraph produces a significant improvement in contrast with multi-band light sources.

Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1963

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

The long-term effects of biosolids on rangeland soil quality and plant community in the central Interior of British Columbia
Creators: name: Avery, Emelia
Publisher: name: University of British Columbia
Year: 2018

description: Biosolids have been shown to improve forage production and soil quality on semi-arid rangelands in the short-term. The objective of this study was to assess the long-term effects of a single, surface biosolids application on rangeland soil quality, forage production and plant community composition. In 2002, the experiment was established on a ranch in the central Interior of British Columbia, where two treatments were evaluated: surface biosolids application at 20 Mg ha-¹ and a control (no biosolids). Both treatments were replicated in four blocks, which were then excluded from grazing for 14 years. In 2016, soil samples were collected in April, June, August and October to assess various soil quality indicators, while forage quality indicators were assessed in June 2016. Fourteen years following the biosolids application, aboveground plant biomass was almost two times greater with biosolids application than on control. Exposed mineral soil was significantly decreased in biosolids plots. Despite differences in aboveground biomass there was no difference in total soil C, permanganate-oxidizable C, or aggregate-protected total C and polysaccharides contents between biosolids and control plots. However, biosolids amended soil did exhibit significantly greater aggregate stability, lower pH, increased spring soil water content, and increased availability of soil P, Fe, Zn and Cu. Forage grown on biosolids plots had lower protein concentrations than control plots, but greater total protein due to the greater biomass. The biosolids application resulted in higher cover of native bluebunch wheatgrass in the long-term, along with >25% cover of agronomic perennial, Kentucky bluegrass. These results offer a demonstration of the potential long-term improvement in forage production that can occur under biosolids application without grazing, which was accompanied by somewhat mixed effects on soil quality and plant species composition.

description: O ronco e a apneia obstrutiva do sono (AOS) são distúrbios respiratórios comuns que podem ter um impacto significativo na saúde e na qualidade de vida. Compreender esses distúrbios e as opções de tratamento disponíveis é fundamental para o bem-estar geral. sintomas como sono fragmentado, insônia, roncos e sonolência diurna excessiva, sendo confirmado pelo exame de polissonografia. O ronco é um ruído respiratório produzido durante o sono, geralmente causado pela vibração dos tecidos da garganta relaxados, As causas comuns incluem obesidade, consumo de álcool, tabagismo, congestão nasal e anatomia da garganta. Embora o ronco ocasional possa ser inofensivo, o ronco crônico pode perturbar o sono e afetar os relacionamentos. A AOS é um distúrbio do sono caracterizado por pausas repetidas na respiração durante o sono, causadas pelo bloqueio das vias aéreas. Os sintomas incluem ronco alto, sonolência diurna excessiva, despertares frequentes, dores de cabeça matinais e dificuldade de concentração. CPAP (Pressão Positiva Contínua nas Vias Aéreas): Continua sendo o tratamento padrão ouro, mas novas interfaces e tecnologias tornaram o CPAP mais confortável e eficaz a qualidade de vida dos pacientes. As estratégias de tratamento variam desde mudanças no estilo de vida, perda de peso, uso de CPAP, até intervenções cirúrgicas e dispositivos implantáveis. A busca por alternativas terapêuticas eficazes continua a impulsionar o desenvolvimento de novas tecnologias e abordagens personalizadas. Assim, a SAHOS representa um desafio multifacetado que exige diagnóstico precoce e gestão contínua para prevenir complicações graves e melhorar a saúde geral e a qualidade de vida dos pacientes.

The effect of coronal radiation on a residual inner disk in the low/hard spectral state of black hole X-ray binary systems

description: Thermal conduction between a cool accretion disk and a hot inner corona can result in either evaporation of the disk or condensation of the hot corona. At low mass accretion rates, evaporation dominates and can completely remove the inner disk. At higher mass accretion rates, condensation becomes more efficient in the very inner regions, so that part of the mass accretes via a weak (initially formed) inner disk which is separated from the outer disk by a fully evaporated region at mid radii. At still higher mass accretion rates, condensation dominates everywhere, so there is a continuous cool disk extending to the innermost stable circular orbit. We extend these calculations by including the effect of irradiation by the hot corona on the disk structure. The flux which is not reflected is reprocessed in the disk, adding to the intrinsic thermal emission from gravitational energy release. This increases the seed photons for Compton cooling of the hot corona, enhancing condensation of the hot flow and re-inforcing the residual inner disk rather than evaporating it. Our calculations confirm that a residual inner disk can co-exist with a hard, coronally dominated, spectrum over a range of $0.006

Neo-FOTT: Interdisciplinary Synthesis with the Inversion Point Principle
Creators: name: Neo
Publisher: name: Zenodo
Year: 2025

description: A concise, revised edition of the Neo-FOTT framework that weaves in the Inversion Point Principle, along with key insights from Noether, Barad, and Friston. It expands the wave-phase model of fluidic time into broader domains—quantum theory, biology, cognition, and large-scale cosmology—offering a unified perspective on how emergent wave-phase coherence might underlie phenomena traditionally explained by dark matter, dark energy, or purely classical field theory.

description: We present results on the nucleon electromagnetic form factors within lattice QCD using two flavors of degenerate twisted mass fermions. Volume effects are examined using simulations at two volumes of spatial length L=2.1 fm and L=2.8 fm. Cut-off effects are investigated using three different values of the lattice spacings, namely a=0.089 fm, a=0.070 and a=0.056 fm. The nucleon magnetic moment, Dirac and Pauli radii are obtained in the continuum limit and chirally extrapolated to the physical pion mass allowing for a comparison with experiment.

description: [Abridged] To investigate the evolution in the relation between galaxy stellar and central black hole mass we construct a volume limited complete sample of 85 AGN with host galaxy stellar masses M_{*} > 10^{10.5} M_{sol}, and specific X-ray luminosities L_{X} > 2.35 x 10^{43} erg s^{-1} at 0.4 < z < 3. We calculate the Eddington limiting masses of the supermassive black holes residing at the centre of these galaxies, and observe an increase in the average Eddington limiting black hole mass with redshift. By assuming that there is no evolution in the Eddington ratio (μ) and then that there is maximum possible evolution to the Eddington limit, we quantify the maximum possible evolution in the M_{*} / M_{BH} ratio as lying in the range 700 < M_{*}/M_{BH} < 10000, compared with the local value of M_{*}/M_{BH} ~ 1000. We furthermore find that the fraction of galaxies which are AGN (with L_{X} > 2.35 x 10^{43} erg s^{-1}) rises with redshift from 1.2 +/- 0.2 % at z = 0.7 to 7.4 +/- 2.0 % at z = 2.5. We use our results to calculate the maximum timescales for which our sample of AGN can continue to accrete at their observed rates before surpassing the local galaxy-black hole mass relation. We use these timescales to calculate the total fraction of massive galaxies which will be active (with L_{X} > 2.35 x 10^{43} erg s^{-1}) since z = 3, finding that at least ~ 40% of all massive galaxies will be Seyfert luminosity AGN or brighter during this epoch. Further, we calculate the energy density due to AGN activity in the Universe as 1.0 (+/- 0.3) x 10^{57} erg Mpc^{-3} Gyr^{-1}, potentially providing a significant source of energy for AGN feedback on star formation. We also use this method to compute the evolution in the X-ray luminosity density of AGN with redshift, finding that massive galaxy Seyfert luminosity AGN are the dominant source of X-ray emission in the Universe at z < 3.

description: We investigate refocusing and strong refocusing of light rays in a space-time. A strongly refocusing space-time is refocusing. The converse is unknown. We construct examples of space-times which are refocusing, but not strongly so, at a particular point. These space-times are strongly refocusing at other points. The geometrization conjecture proved by Perelman implies that a globally hyperbolic refocusing space-time of dimension $\leq 4$ admits a strongly refocusing Lorentz metric. We show that the possibly empty set of points at which a strongly causal space-time is refocusing is closed. We prove that a Lorentz covering space of a strongly causal refocusing space-time is a strongly causal refocusing space-time. This generalizes the result of Chernov and Rudyak for globally hyperbolic space-times.

description: We consider the existence, stability and dynamics of the ground state and nonlinear excitations, in the form of dark solitons, for a quasi-one-dimensional polariton condensate in the presence of pumping and nonlinear damping. We find a series of remarkable features that can be directly contrasted to the case of the typically energy-conserving ultracold alkali-atom Bose-Einstein condensates. For some sizeable parameter ranges, the nodeless ("ground") state becomes {\it unstable} towards the formation of {\em stable} nonlinear single or {\em multi} dark-soliton excitations. It is also observed that for suitable parametric choices, the instability of single dark solitons can nucleate multi-dark-soliton states. Also, for other parametric regions, {\em stable asymmetric} sawtooth-like solutions exist. Finally, we consider the dragging of a defect through the condensate and the interference of two initially separated condensates, both of which are capable of nucleating dark multi-soliton dynamical states.

description: Let $ξ$ be an algebraic number and let $α,β\in \mathbb Q[ξ]$. An explicit formula for the coordinates of the product $αβ$ is given in terms of the coordinates of $α$ and $β$ and the companion matrix of the minimal polynomial of $ξ$. The formula as well as its proof extend to fairly general simple integral extensions.
