description: Vitamin D deficiency is one of the common clinical symptoms of severe chronic kidney disease (CKD) patients. Vitamin D receptor (VDR) is a part of the nuclear receptor family exerts vitamin D activation to maintain calcium/phosphorous homeostasis and bone metabolism. The reduction of VDR activity leads to vitamin D deficiency. In this study, we found three potent agonists for VDR protein on the structure and ligand-based screening methods. In the structure-based method, 792 compounds were screened. A 5-point pharmacophore (one hydrogen bond acceptor, two hydrophobic and aromatic rings (AHHRR)) was developed and used to obtain a predictive 3D-Quantitative structure-activity relationship (QSAR), model. The acquire R2 and Q2 values are 0.8676 and 0.8523 respectively. Further, E-pharmacophore based screening, molecular docking (binding affinity), Molecular Mechanics-Generalized Born Surface Area (binding free energy), chemical reactivity (Density Functional Theory (DFT) study) and molecular dynamics (protein-ligand stability) analysis were done. Hence, the computational investigations demonstrate that the identified ligands such as TCM_1875, TCM_1874, and TCM_2868 showed promising agonist effect on VDR protein. Further validation and experiments need to be done to confirm the potency of the identified compounds shortly.

description: Luminous $z\ge7$ quasars provide direct probes of the evolution of supermassive black holes (SMBHs) and the intergalactic medium (IGM) during the epoch of reionization (EoR). The Ly$α$ damping wing absorption imprinted by neutral hydrogen in the IGM can be detected in a single EoR quasar spectrum, allowing the measurement of the IGM neutral fraction towards that line of sight. However, damping wing features have only been detected in two $z>7$ quasars in previous studies. In this paper, we present new high quality optical and near-infrared spectroscopy of the $z=7.00$ quasar DES J025216.64--050331.8 obtained with Keck/NIRES and Gemini/GMOS. By using the MgII single-epoch virial method, we find that it hosts a $\rm (1.39\pm0.16) \times10^{9} ~M_\odot$ SMBH accreting at an Eddington ratio of $λ_{\rm Edd}=0.7\pm0.1$, consistent with the values seen in other luminous $z\sim 7$ quasars. Furthermore, the Ly$α$ region of the spectrum exhibits a strong damping wing absorption feature. The lack of associated metal absorption in the quasar spectrum indicates that this absorption is imprinted by a neutral IGM. Using a state-of-the-art model developed by Davies et al., we measure a volume-averaged neutral hydrogen fraction at $z=7$ of $\langle x_{\rm HI} \rangle = 0.70^{+0.20}_{-0.23} (^{+0.28}_{-0.48})$ within 68% (95%) confidence intervals when marginalizing over quasar lifetimes of $10^3\le t_{\rm Q}\le10^8$ yr. This is the highest IGM neutral fraction yet measured using reionization-era quasar spectra.

description: In this paper, we have studied the effect of strain relaxation on magneto-transport properties of La_0.7Ca_0.3MnO_3 epitaxial films (200 nm thick), which were deposited by pulsed laser deposition technique under identical conditions. All the films are epitaxial and have cubic unit cell. The amount of strain relaxation has been varied by taking three different single crystal substrates of SrTiO_3, LaAlO_3 and MgO. It has been found that for thicker films the strain gets relaxed and produces variable amount of disorder depending on the strength of strain relaxation. The magnitude of lattice relaxation has been found to be 0.384, 3.057 and 6.411 percent for film deposited on SrTiO_3, LaAlO_3 and MgO respectively. The films on LaAlO_3 and SrTiO_3 show higher T_{IM} of 243 K and 217 K respectively as compared to T_{IM} of 191 K for the film on MgO. Similarly T_C of the films on SrTiO_3 and LaAlO_3 is sharper and has value of 245 K and 220 K respectively whereas the TC of the film on MgO is 175 K. Higher degree of relaxation creates more defects and hence TIM (T_C) of the film on MgO is significantly lower than of SrTiO_3 and LaAlO_3. We have adopted a different approach to correlate the effect of strain relaxation on magneto-transport properties of LCMO films by evaluating the resistivity variation through Mott's VRH model. The variable presence of disorder in these thick films due to lattice relaxation which have been analyzed through Mott's VRH model provides a strong additional evidence that the strength of lattice relaxation produces disorder dominantly by increase in density of defects such as stacking faults, dislocations, etc. which affect the magneto-transport properties of thick epitaxial La_0.7Ca_0.3MnO_3 films.

description: Aim: The aim of this work was to develop buccoadhesive tablets for the systemic delivery of duloxetine HCl (DXT) using more soluble derivatives of β-cyclodextrin, i.e. hydroxypropyl-β-cyclodextrin (HPβCD) and sulfobutylether-β-cyclodextrin (SBEβCD) and to investigate enhanced cellular uptake of inclusion complexed drug. Materials and methods: Freeze dried and spray dried complexes of both cyclodextrin derivatives with DXT (1:1 molar) were prepared and characterized with DSC, FTIR, and PXRD techniques. C971 and PC, on the basis of swelling behavior, erosion and in vitro residence time, were selected for further study at different levels (−1, 0, +1) to optimize the formulation in terms of enhanced drug release and ex vivo permeation. Results: SBEβCD based complexes show more aqueous solubility of DXT (0.782 and 0.958 mM) and more complexation efficiency compared to HPβCD at 25 °C and 37 °C, respectively. Apparent stability constant was reported to be higher (1109.94 and 1693.25 M−1) for DXT-SBEβCD at 25 °C and 37 °C, respectively, than the corresponding values for DXT-HPβCD systems. Enhanced cellular uptake using fibroblast cells was revealed for complexed drug compared to free drug . Conclusion: Both cyclodextrin derivatives are able to enhance drug release and permeation in vitro and ex vivo.

description: The analysis of the affect of angular velocity on the geometry of the basins of convergence (BoC) linked to the equilibrium points in the restricted three-body problem is illustrated when the primaries are source of radiation. The bivariate scheme of the Newton-Raphson (N-R) iterative method has been used to discuss the topology of the basins of convergence. The parametric evolution of the fractality of the convergence plane is also presented where the degree of fractality is illustrated by evaluating the basin entropy of the convergence plane.

description: The rusticyanin protein, a blue monomeric copper protein type-1, is one of the main components in the iron-electron transfer chain of the Acidithiobacillus ferrooxidans, and is the product of the rus gene expression. Herein, first the bacterial DNA of Acidithiobacillus sp. FJ2 was extracted. Then, the rus gene sequence and the sequence amino acid rusticyanin protein were determined. The Met148Leu mutation increased the oxidase activity of the rusticyanin protein, thereby enhancing the efficiency of the bioleaching process by bacteria Acidithiobacillus ferroxidans. Met148Leu mutation was created in the rusticyanin protein, then molecular dynamics (MD) simulations and structural analysis were performed. The MD analysis of the wild-type and mutant protein demonstrated a slight instability in the mutant protein and significant instability in the active site of the mutant protein. The usefulness of this study is the genetic manipulation of the native Acidithiobacillus sp. FJ2 bacterium, which can boost the bioleaching efficiency of the bacterium to some extent, and investigating its effects on the structure of a mutant protein using computational methods.

Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.

description: The ‘LEADER community initiatives’ and the ‘LEADER approach’ have been commonly accepted as an innovative way for development of rural areas in the EU. It is widely assumed that promoting growth in rural areas can be achieved through partnerships between representatives of three classes of local actors: civil society, public administration and private/economic sector. While these partnerships certainly have the potential to improve coordination mechanisms that manage local resources, their existence is likely to have an impact on the distribution of political advantages and future economic rents of current incumbents. What follows, it is reasonable to assume that local political elites may either block or impede the adoption of this institutional innovation. This paper investigates these issues using the Pilot Programme LEADER+ experiences in Poland. The focus is on institutional aspects that are thought to affect the electoral process. Consistent with a large body of political economy literature, our results suggest that LEADER-type partnerships are more likely to occur in an environment where holding politicians to account is easier.

description: In a context of growing global threats, from climate change, the depletion and degradation of natural resources, to the recent global economic crisis, consequences of short and long term are being witnessed, which undermine the agriculture sustainability. The systems vulnerability, their inability to resilience and the need for innovation is observed, emphasizing also the most capable systems (more sustainable), offering new opportunities and encouraging more environmentally friendly practices. This work takes as starting point the evolution of economic, environmental and social parameters in farms, in recent years, in order to try to identify the difficulties and the solutions capable of sustaining agriculture in the context of multiple hazards at the farm level. The main methodology focuses on inquiries to the responsible agents for developing the main agriculture activities held in Trás-os-Montes, including farmers and their associations. The results confirm the dependence of production factors outside the farm, the limited availability and the high cost of manpower, the weakness of marketing channels and the poor organization of the sector as the main problems. Effective responses to these situations are the opportunities of the activities under study: (a) establishment of an organized marketing circuit, (b) strengthening of mutual help between farms, (c) collective use of inputs, (d) use of environmentally friendly production practices, (e) self-use of products produced on the farm, strengthening their autonomy. This work proposes the society valuation for different levels of agriculture intensity, through discrete choices methodology, to identify the real importance that society attributes to the agrarian activity.

description: The reaction between dialkyl 8-oxo-8H-cyclopenta[a]acenaphthylene-7,9-dicarboxylates and zwitterionic intermediates, generated in situ from alkyl isocyanides and dialkyl acetylenedicarboxylates, is described. This reaction leads to the formation of tetraalkyl 5′-(alkylimino)-5′H-spiro[cyclopenta[a]acenaphthylene-8,2′-furan]-3′,4′,7,9-tetracarboxylates. The structure of a typical product was confirmed by X-ray crystallographic analysis.

description: We study dynamics of a D3-brane propagating in the vicinity of k coincident NS5 branes. We show that when $g_s$ is small, there exists a regime in which dynamics of the D-brane is governed by Dirac-Born-Infeld action while higher order derivative in the expansion can not be neglected. This leads to a restriction on how fast scalar field may roll. We analyze the motion of a rolling scalar field in this regime, and extend the analysis to cosmological systems obtained by coupling this type of field theory to four dimensinal gravity. It also leads to some FRW cosmologies, some of which are related to those obtained with tachyon matter.

description: Consumers in developed countries are increasingly interested in the consumption of food products incorporating ethical aspects, particularly fair trade products. These products are usually distributed in a network of World Shops and, more recently, in supermarkets and shopping centres. The fair trade product with the highest market share is coffee. This study aims to ascertain the implicit price paid by Italian consumers for the fair trade content of coffee and how this implicit price is influenced by the level of social capital of the territory where consumers live. The data utilised are scanner data, based on the purchase at supermarkets and shopping centres observed from 2005 to 2007, referred to a territorial unit that is the province. Since scanner data are used, the analysis can allow for the coffee attributes described by the labels: branded, organic, decaffeinated, fair trade, espresso, and so on. The approach followed is the application of an hedonic regression where the dependant variable is the coffee price while the regressors are coffee characteristics (fair trade content and coffee other attributes) and several indicators of provincial social capital, alternatively included.
Extending the idea of compressed algebra to arbitrary socle-vectors, II: cases of non-existence

description: This paper is the continuation of the previous work on generalized compressed algebras (GCA's). First we exhibit a new class of socle-vectors $s$ which admit a GCA (whose $h$-vector is lower than the upper-bound $H$ of Theorem A of the previous paper). In particular, it follows that for every socle-vector $s$ of type 2 there exists a GCA (in any codimension $r$). The main result of this paper is the following: there exist pairs $(r,s)$ which do not admit a GCA. Moreover, the way this pathology occurs may be "arbitrarily bad" (even in codimension 3). Finally, we start considering the difficult problem of characterizing the pairs $(r,s)$ which admit a GCA, focusing on a particular class of socle-vectors of codimension 3.

Tip-tilt Error in Lyot Coronagraphs

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The direct detection of extrasolar planets by imaging means is limited by the large flux of light from the host star being scattered into the region of interest by a variety of processes, including diffraction. Coronagraphs are devices that suppress the undesirable scattering of light caused by diffraction. In a coronagraph the sensitivity limit for high dynamic range is limited by the propagation of errors introduced by the imperfect optical system to the final image. In this paper we develop theory and simulations to understand how such errors propagate in a coronagraph. We describe the response of classical and band-limited Lyot coronagraphs to small and large errors in the placement of the central star, and identify ways of making such coronagraphs more robust to small guiding errors. We also uncover features of the decentered PSF that can lead to spurious detection of companions, especially with aggressive, high dynamic range coronagraphs dedicated to companion searches aimed at finding extrasolar terrestrial or Jovian planets.

Dynamics of temporal and spatial mercury contamination in an urban watershed
Creators: name: Muraro, Matthew Robert
Publisher: name: University of British Columbia
Year: 2009

description: Mercury is a concern in aquatic environments because it can lead to accumulations of methylmercury in fish, which is the primary source of mercury exposure to humans. The Brunette Watershed is a highly urbanized watershed in metropolitan Vancouver with a rich record of monitoring (1973-2003) trace metal distribution and dynamics. This study was conducted to investigate the 294% increase in Brunette Watershed stream sediment mercury concentrations from 1973-1996. The project conducted analysis of field samples, laboratory experiments and examined previous data to determine if methylcyclopentadienyl manganese tricarbonyl (MMT) may play a role in the increase of mercury in the watershed. Little evidence compiled in this study supported the hypothesis that manganese, iron, sulfur or DOC is associated with mercury throughout the watershed. Thus, it is difficult to conclude or rule out that MMT or manganese oxides play a major role in the transport of total mercury. Laboratory experiments creating summer anoxic conditions released a significant amount of mercury from lake sediment into overlying waters. It seems that this release of mercury may be controlled by sulfate reducing bacteria. The study also found an analysis method used in the study caused 66.8% mean loss of mercury in stream sediment samples when the samples were dried. Temporal and spatial analysis of sediment data revealed that mercury concentrations have started to decrease since 1993. When sediment concentrations were adjusted for the 66.8% loss in stream sediment, 1993 mercury concentrations exceeded the Federal Interm Sediment Quality Guidelines at 12 locations; but in 2003, only 1 site exceeded the same guideline. The decrease in mercury concentrations may be linked to the increased public awareness and a large reduction of emissions from a nearby refuse incinerator. Effective imperviousness and mercury levels in stream sediment are significantly correlated throughout the period of high mercury releases from the incinerator. This may indicate that atmospheric mercury deposited on impervious surfaces connected to waterways may contribute to increases in stream sediment concentrations.

description: The wastewater treatment and reuse plant of the city of Khouribga (WWTP) carry out a biological treatment of urban waste water in the city. The activated sludge treatment process is the process adopted at the Khouribga WWTP. This treatment is carried out at two aeration basins. Although the purifying performance of the WWTP and the reliability of this process are proven, several types of biological dysfunctions of the aeration basins can appear. The results of the biological treatment obtained showed that the elimination yield of the physicochemical parameters was 92; 98.4; 96.5 and 97.1 respectively for COD, BOD5, TSS and turbidity. Generally, the main dysfunction noted in the aeration basin of the WWTP is the proliferation of filamentous bacteria associated with poor settling. This swelling problem leads to poor settling of the mud following an increase in the volume occupied by it. Significant filamentary development severely limits the hydraulic capacity of the clarifier and can cause sludge to leave the natural environment.

description: The energy-level scheme and wave functions of the titanium ions in LaTiO$_{3}$ are calculated using crystal-field theory and spin-orbit coupling. The theoretically derived temperature dependence and anisotropy of the magnetic susceptibility agree well with experimental data obtained in an untwinned single crystal. The refined fitting procedure reveals an almost isotropic molecular field and a temperature dependence of the van Vleck susceptibility. The charge distribution of the 3d--electron on the Ti positions and the principle values of the quadrupole moments are derived and agree with NMR data and recent measurements of orbital momentum $$ and crystal-field splitting. The low value of the ordered moment in the antiferromagnetic phase is discussed.

description: Soil degradation is a global problem that affects many regions and communities, resulting in poor and stress-prone marginal soils. The potentially positive effects of carbon and nutrient content increase through the addition of nutrient-saturated biochar were investigated on poor and saline substrate in experiments with tomato and barley. Biochar treatments were applied to nutrient- and carbon-poor sandy substrates in two greenhouse pot experiments. Biochar mixed with biofertilizers (algae & pig manure) at three total carbon content levels (0.1, 0.3, 0.5 % C-concentration) was applied to test its effects on tomato growth and soil properties during early growth stages. As a follow-up, carbon addition was increased to 2% via a biochar-sheep manure mixture to test its effect on growth parameters and quality of two barley cultivars (Palestinian & German). Results showed that increasing mineral-fertilizer saturated biochar concentration up to 0.5 % total C in saline soil (4 EC) increased tomato total fruit numbers but delayed the ripening process (24% red fruits in untreated pots, 15% in treated pots). In saline environment, biochar-pig manure mixture led to the highest tomato shoot dry weight (41g) compared to 0% biochar treatments (31g). Increased biochar amount (up to 2%) led to increased shoot fresh weight of up to 1.7g in the German barley cultivar after a 1-month growth period, compared to non-treated (0% biochar) pots at 0.9g, respectively. Increasing biochar up to 2% increased the soil water-holding capacity by up to 17% compared to 0% biochar control. In conclusion, nutrient-saturated biochar constitutes a sustainable solution to condition substrates to improve the quality and fertility of the soil by helping to close the nutrient cycle and increasing the water hold capacity, especially in carbon-poor soil substrate. Further up-scaled greenhouse and field experiments are needed to evaluate longer-term effects on yield and soil parameters.

description: Objective of this paper is to analyse the presence of gender differences in the purchase motivations of Fair Trade (FT) food products sold in the Italian World Shops (WS). At this end, a questionnaire has been distributed to a sample of consumers in four Italian regions. A bivariate ordered probit analysis has been performed in order to identify the determinants of the two main ethical motivations in the purchase: worker guarantees and solidarity. The variables used as determinants are individual and municipal characteristics. Among individual characteristics, gender is significant; among the municipal characteristics, the rate of female job market participation is also significant. These results give evidence of a gender gap in the preferences for public goods.

description: An analysis of high-resolution VLT/UVES spectra of two B-type main sequence stars, NGC 346-11 and AV 304, in the Small Magellanic Cloud (SMC), has been undertaken, using the non-LTE TLUSTY model atmospheres to derive the stellar parameters and chemical compositions of each star. The chemical compositions of the two stars are in reasonable agreement. Moreover, our stellar analysis agrees well with earlier analyses of H II regions. The results derived here should be representative of the current base-line chemical composition of the SMC interstellar medium as derived from B-type stars.

description: The Swiss agent-based model (SWISSland) claims to depict as realistically as possible the 50 000 family farms comprising the whole of Swiss agriculture in all their heterogeneity as regards farm and cost structures as well as farm decision-making behaviour and interactions, with the aim of improving the simulation and forecasting of structural change in agriculture. With the linking of different methods and recorded data, there is a marked increase in the quality of the assessment of policy consequences. Simulations are shown for policy measures which affect only farm entry by cutting socially motivated direct payments for young operators.

description: Electron-electron interactions (EEIs) in 2D van der Waals structures is one of the topics with high current interest in physics. We report the observation of a negative parabolic magnetoresistance (MR) in multilayer 2D semiconductor InSe beyond the low-field weak localization/antilocalization regime, and provide evidence for the EEI origin of this MR behavior. Further, we analyze this negative parabolic MR and other observed quantum transport signatures of EEIs (temperature dependent conductance and Hall coefficient) within the framework of Fermi liquid theory and extract the gate voltage tunable Fermi liquid parameter $F_0^σ$ which quantifies the electron spin-exchange interaction strength.

description: There are numerous scenarios in source coding where not only the code length but the importance of each value should also be taken into account. Different from the traditional coding theorems, by adding the importance weights for the length of the codes, we define the average cost of the weighted codeword length as an importance-aware measure of the codes. This novel information theoretical measure generalizes the average codeword length by assigning importance weights for each symbol according to users' concerns through focusing on user's selections. With such definitions, coding theorems of the bounds are derived and the outcomes are shown to be extensions of traditional coding theorems.

description: Agrarian structures are often characterized by some kind of economic inertia. It is particularly puzzling why unprofitable farms persist over time instead of being sold. In this paper we analyze the exit decision of farmers using the real options approach. The validity of the real options theory is assessed by means of laboratory experiments. Our results show that real options models are able to predict actual disinvestment decisions better than traditional investment theory. Nevertheless, the observed disinvestment reluctance was even more pronounced as predicted by theory. This finding suggests the inclusion of bounded rationality into normative disinvestment models.

description: Based on first-principles electron structure calculations and employing the frozen-magnon approximation we study the exchange interactions in a series of transition-metal binary alloys crystallizing in the zinc-blende structure and calculate the Curie temperature within both the mean-field approximation (MFA) and random-phase approximation (RPA). We study two Cr compounds, CrAs and CrSe, and four Mn compounds: MnSi, MnGe, MnAs and MnC. MnC, MnSi and MnGe are isovalent to CrAs and MnAs is isoelectronic with CrSe. Ferromagnetism is particular stable for CrAs, MnSi and MnGe: All three compounds show Curie temperatures around 1000 K. On the other hand, CrSe and MnAs show a tendency to antiferromagnetism when compressing the lattice. In MnC the half-metallic gap is located in the majority-spin channel contrary to the other five compounds. The large half-metallic gaps, very high Curie temperatures, the stability of the ferromagnetism with respect to the variation of the lattice parameter and a coherent growth on semiconductors make MnSi and CrAs most promising candidates for the use in spintronics devises.

description: We report the results of the first directional point-contact measurements in Mg(B_{1-x}C_{x})_2 single crystals with 0.047 <= x <= 0.132. The two-gap superconductivity typical of MgB_2 persists up to x=0.105. In this region, the values of the gaps Delta_{sigma} and Delta_{pi} were determined by fitting the Andreev-reflection conductance curves with a two-band Blonder-Tinkham-Klapwijk (BTK) model, and confirmed by the single-band BTK fit of the sigma- and pi-band conductances, separated by means of a magnetic field. At x=0.132, when T_{c}=19 K, we clearly observed for the first time the merging of the two gaps into one of amplitude Delta~3 meV.

"China round the corner" : Vancouver’s Chinatown and the Chinese community in a changing "multicultural" society
Creators: name: Nakamura, Mayumi
Publisher: name: University of British Columbia
Year: 2009

description: This thesis conceptualizes Vancouver's Chinatown as a museum aimed at the white population groups in the context of multicultural Canadian society. The purpose of this research is to suggest that a dichotomization between whites and Chinese resulting from colonialism is reproduced through the policy of multiculturalism. Explicit visualization for the purpose of "preservation" made Chinese culture a subordinate and exploitable object that served as a source of entertainment for whites. The Chinese in Canada, who had greatly suffered from racial discrimination in the past, are now regarded as an important ethnic and cultural group that enriches Canadian society under the policy of multiculturalism. However, it remains to be seen whether they and their culture have truly earned equal status to that of white culture. The City of Vancouver conducted beautification schemes on Chinatown from the late 1960s to the 1980s. As a result, Chinatown became a cultural site where Chinese culture is represented with a strong emphasis on visual aspects. Preservation of Chinatown as a cultural entity consequently made it an artificial space that does not reflect the reality of the current, diversified Chinese community. Therefore, people of Chinese origin today cannot identify themselves with Chinatown. Chinatown was forced to remain distinctive from the rest of the City, and its distinctiveness was measured in comparison to white culture. This implies an unbridgeable distance between the white and Chinese. In this research, archives regarding the beautification of Chinatown were examined to study what modifications were added and what aspects of Chinese culture were emphasized to create an imaginary space of Chinese culture for whites. Most of the materials studied for this research were published by the City of Vancouver. They were employed to reflect images of "authentic" Chinese culture shared by whites. These sources were also useful to reveal how multiculturalism further promoted the dichotomization between whites and Chinese by keeping the Chinese and their culture distinctive.

description: Differential equations are frequently used in engineering domains, such as modeling and control of industrial systems, where safety and performance guarantees are of paramount importance. Traditional physics-based modeling approaches require domain expertise and are often difficult to tune or adapt to new systems. In this paper, we show how to model discrete ordinary differential equations (ODE) with algebraic nonlinearities as deep neural networks with varying degrees of prior knowledge. We derive the stability guarantees of the network layers based on the implicit constraints imposed on the weight's eigenvalues. Moreover, we show how to use barrier methods to generically handle additional inequality constraints. We demonstrate the prediction accuracy of learned neural ODEs evaluated on open-loop simulations compared to ground truth dynamics with bi-linear terms.
