description: There is no single approach to the concept of investment in Russian legislation. There is no single approach to the emu concept in the scientific community. Such terms as investment, investment, capital, capital investment are often used as synonyms. Given that investment, capital, and capital investment are primarily economic, it seems quite reasonable to consider the emergence and development of these concepts in the retrospect of economic theories, in order to understand the essence of the phenomenon and finally solve the issue of its legal regulation. In this article, the author examines the positions of the first economists who consider investment issues in their works: Richard Catillon, Francois Quesnay, Jacques Turgot and Adam Smith.

description: The inclusive K^+ momentum spectrum in the 12C(K^-,K^+) reaction is calculated by the semiclassical distorted wave (SCDW) model, including the transition to the Ξ^- bound state. The calculated spectra with the strength of the Ξ^--nucleus potential -50, -20, and +10 MeV are compared with the experimental data measured at KEK with p_{K^-}=1.65 GeV/c. The shape of the spectrum is reproduced by the calculation. Though the inclusive spectrum changes systematically depending on the potential strength, it is not possible to obtain a constraint on the potential from the present data. The calculated spectrum is found to have strong emission-angle dependence. We also investigate the incident K^- momentum dependence of the spectrum to see the effect of the Fermi motion of the target nucleons which is explicitly treated in the SCDW method.

PALAEOBIOLOGICAL OBSERVATIONS ON THE "COCOONED" MYTILID AMYGDALUM (BIVALVIA, UPPER PLIOCENE)

description: Fossil specimens referred to the extant Atlantic-Mediterranean species Amygdalum politum (Verrill & Smith, 1880), occur in Upper Pliocene mudstones cropping out in northern Puglia (Southern Italy). Amygdalum is an infaunal mytilid living within a cocoon made of byssal threads, sediment and mucus. The examined material occurs in grey clayey silt, mainly massive, and in stratified yellowish clayey silt. The specimens from the grey mudstones are closed, strongly compressed, deformed and obliquely oriented. Also in the yellowish mudstones the shells are closed, compressed and intensely fractured but are concordant to the bedding plane and concentrated in a single pavement. On a whole, the associated macrofauna is indicative of upper slope tending to outer shelf environments. Taphonomic and palaeoecologic observations, together with the few available literature data, suggest that this bivalve lived in a particularly fluid substrate, keeping its vertical life position thanks to the stabilizing effect of the byssal cocoon. Since this species was able to cope with high turbidity waters, as suggested by taphonomic observation, it can be argued that the byssal cocoon acted also as a filter for the inhalant current.

Toward an in-situ glucose biosensor for animal cell culture monitoring and control
Creators: name: Fong, Fenton
Publisher: name: University of British Columbia
Year: 2009

description: This thesis describes the development and characterization of an in-situ sterilizable, regenerable biosensor for monitoring and control of glucose concentration in bioreactorscale animal cell culture. Long-term stability and in-situ steam sterilization capability are obstacles preventing development of industrially acceptable biosensors. These difficulties are magnified in animal cell culture applications given their longer duration and high susceptibility to microbial contamination. A novel enzyme immobilization technology is presented which helps address these difficulties. The developmental starting point utilized an existing prototype originally designed for microbial culture applications. The prototype contains a cellulose matrix sandwiched between a platinum electrode and a dialysis membrane. Glucose oxidase enzyme, chemically conjugated with cellulose binding domain protein, is easily immobilized to and removed from the cellulose. An improved conjugation protocol yielding conjugate with higher specific activity is described. Conjugate was characterized for binding characteristics to cellulose and lower detection limit during prototype use. Binding experiments were the first for characterizing a heterogeneous chemical fusion of these proteins. Re-design of the prototype membrane assembly and incorporation of continuous perfusion are described and were necessary modifications to produce a functional prototype for animal cell culture. Longer term sensor signal stability was characterized and enhanced. A first-order equation adequately described signal decay behavior during the first long-term experiment. The combination of hardware modifications resulted in ca. 2.5-fold increase in signal stability during controlled environment conditions. A subsequent cell culture experiment revealed enhanced signal stability; although, undefined factors resulted in inconsistent decay patterns. A Chinese hamster ovary cell line was transfected with pNUT plasmid expressing H6E2FX protein to develop a model cell line for culture and glucose studies utilizing the prototype. Positive subclones, after adaptation to serum-free medium over 7 weeks, displayed undetectable levels of H6E2FX. Several possible explanations could account for unstable expression but no specific one was determined. Described hardware modifications yielded a prototype functional for longer periods of time and with enhanced signal stability. Stability experiments are the first for characterizing longer term prototype signal behavior. Results in this thesis contribute to existing data demonstrating the feasibility and potential of this biosensor technology for implementation in industrial bioprocesses.

description: This paper uses new and recently introduced methodologies to study the similarity in the dynamics and behaviours of cryptocurrencies and equities surrounding the COVID-19 pandemic. We study two collections; 45 cryptocurrencies and 72 equities, both independently and in conjunction. First, we examine the evolution of cryptocurrency and equity market dynamics, with a particular focus on their change during the COVID-19 pandemic. We demonstrate markedly more similar dynamics during times of crisis. Next, we apply recently introduced methods to contrast trajectories, erratic behaviours, and extreme values among the two multivariate time series. Finally, we introduce a new framework for determining the persistence of market anomalies over time. Surprisingly, we find that although cryptocurrencies exhibit stronger collective dynamics and correlation in all market conditions, equities behave more similarly in their trajectories, extremes, and show greater persistence in anomalies over time.

Is it Great or Terrible? Preserving Sentiment in Neural Machine Translation of Arabic Reviews

description: Since the advent of Neural Machine Translation (NMT) approaches there has been a tremendous improvement in the quality of automatic translation. However, NMT output still lacks accuracy in some low-resource languages and sometimes makes major errors that need extensive post-editing. This is particularly noticeable with texts that do not follow common lexico-grammatical standards, such as user generated content (UGC). In this paper we investigate the challenges involved in translating book reviews from Arabic into English, with particular focus on the errors that lead to incorrect translation of sentiment polarity. Our study points to the special characteristics of Arabic UGC, examines the sentiment transfer errors made by Google Translate of Arabic UGC to English, analyzes why the problem occurs, and proposes an error typology specific of the translation of Arabic UGC. Our analysis shows that the output of online translation tools of Arabic UGC can either fail to transfer the sentiment at all by producing a neutral target text, or completely flips the sentiment polarity of the target word or phrase and hence delivers a wrong affect message. We address this problem by fine-tuning an NMT model with respect to sentiment polarity showing that this approach can significantly help with correcting sentiment errors detected in the online translation of Arabic UGC.

description: Both the trapping geometry and the interatomic interaction strength of a dilute ultracold fermionic gas can be well controlled experimentally. When the interactions are tuned to strong attraction, Cooper pairing of neutral atoms takes place and a BCS superfluid is created. Alternatively, the presence of Feshbach resonances in the interatomic scattering allows populating a molecular (bound) state. These molecules are more tightly bound than the Cooper pairs and can form a Bose-Einstein condensate (BEC). In this contribution, we describe both the BCS and BEC regimes, and the crossover, from a functional integral point of view. In this description, the properties of the superfluid (such as vortices and Josephson tunneling) can be derived and followed as the system is tuned from BCS the BEC. In particular, we present results for the critical current of the superfluid through an optical lattice and link these results to recent experiments with atomic bosons in optical lattices.

Publisher: name: trends in Agriculture Science
Year: 2024

description: Glycolipids, derived from various Pseudomonas strains, possess unique surface-active properties, driving extensive research across industries. Their molecular composition, production methods, and distinct physicochemical characteristics enhance their efficacy as surfactants. In health and medicine, these glycolipids have diverse applications, showing potential in drug delivery, antimicrobial properties, wound healing, and therapeutic interventions. Their eco-friendly attributes, such as biodegradability, position them as sustainable alternatives in healthcare. Rhamnolipids (RLs), mainly from Pseudomonas aeruginosa, gain recognition in fields like food, healthcare, and pharmaceuticals for their non-toxicity, biodegradability, reduced surface tension, and low inhibitory concentration. Investigating Pseudomonas-derived glycolipids as microbial surfactants holds promise for advancing medical technologies and addressing healthcare challenges.

description: The problem of a solute described by Quantum Chemistry within a solvent represented as a polarizable continuum model (PCM) is here reformulated in terms of the open quantum systems (OQS) theory. Using its stochastic Schrödinger Equation formulation, we are able to provide a more comprehensive picture of the electronic energies and of the coupling between solute and solvent electronic dynamics. In particular, OQS-PCM proves to be a unifying theoretical framework naturally including polarization and dispersion interactions, the effect of solvent fluctuations, and the non-Markovian solvent response. As such, the OQS-PCM describes the interplay between the solute and the solvent typical electronic dynamical times, and yields both the standard PCM and the so-called Born Oppenheimer solvation regime, where the solvent electronic response is considered faster than any electronic dynamics taking place in the solute. In analyzing the OQS-PCM, we obtained an expression for the solute-solvent dispersion (van der Waals) interactions that is very transparent in terms of a physical interpretation based on fluctuations and response functions. Finally, we present various numerical tests that support the theoretical findings

description: Collaborator finding systems are a special type of expert finding models. There is a long-lasting challenge for research in the collaborator recommending research area, which is the lack of the structured dataset to be used by the researchers. We introduce two datasets to fill this gap. The first dataset is prepared for designing a consistent, collaborator finding system. The next one, called a co-author finding model, models an academic social network as a table that contains different relations between the pair of users. Both of them provide an opportunity for introducing potential collaborators to each other. These two models have been extracted from ResearchGate (RG) data set and are available publicly. RG dataset has been collected from Jan. 2019 to April 2019 and includes raw data of 3980 RG users. The dataset consists of almost complete information about users. In the preprocessing phase, the well-known Elmo was used for analyzing textual data. We call this as ResearchGate dataset for Recommending Systems (RGRS). For assessing the validity of data, we analyze each layer of data separately, and the results are reported. After preparing data and evaluating the collaborator finding models, we have done some assessments on RGRS. Some of these assessments are co-author, following-follower, and question answering relations. The outcomes indicate that it is the best relation in propagating knowledge in the network. To the best of our knowledge, there is no processed and analyzed dataset of this size.

description: In classical general relativity, the generic approach to the initial singularity is usually understood in terms of the BKL scenario. In this scenario, along with the Bianchi IX model, the exact, singular, Kasner solution of vacuum Bianchi I model also plays a pivotal role. Using an effective classical Hamiltonian obtained from loop quantization of vacuum Bianchi I model, exact solution is obtained which is non-singular due to a discreteness parameter. The solution is parameterized in exactly the same manner as the usual Kasner solution and reduces to the Kasner solution as discreteness parameter is taken to zero. At the effective Hamiltonian level, the avoidance of Kasner singularity uses a mechanism distinct from the `inverse volume' modifications characteristic of loop quantum cosmology.

Recursive CSI Quantization of Time-Correlated MIMO Channels by Deep Learning Classification

description: In frequency division duplex (FDD) multiple-input multiple-output (MIMO) wireless communications, limited channel state information (CSI) feedback is a central tool to support advanced single- and multi-user MIMO beamforming/precoding. To achieve a given CSI quality, the CSI quantization codebook size has to grow exponentially with the number of antennas, leading to quantization complexity, as well as, feedback overhead issues for larger MIMO systems. We have recently proposed a multi-stage recursive Grassmannian quantizer that enables a significant complexity reduction of CSI quantization. In this paper, we show that this recursive quantizer can effectively be combined with deep learning classification to further reduce the complexity, and that it can exploit temporal channel correlations to reduce the CSI feedback overhead.

description: A widely used relativistic Fermi gas model and plane-wave impulse approximation are tested against electron-nucleus scattering data. Inclusive quasi-elastic cross section are calculated and compared with high-precision data for C, O, and Ca. A dependence of agreement between calculated cross section and data on a momentum transfer is shown. Results for the C(nu_mu,mu) reaction are presented and compared with experimental data of the LSND collaboration.

description: What if emotion could be captured in a general and subject-agnostic fashion? Is it possible, for instance, to design general-purpose representations that detect affect solely from the pixels and audio of a human-computer interaction video? In this paper we address the above questions by evaluating the capacity of deep learned representations to predict affect by relying only on audiovisual information of videos. We assume that the pixels and audio of an interactive session embed the necessary information required to detect affect. We test our hypothesis in the domain of digital games and evaluate the degree to which deep classifiers and deep preference learning algorithms can learn to predict the arousal of players based only on the video footage of their gameplay. Our results from four dissimilar games suggest that general-purpose representations can be built across games as the arousal models obtain average accuracies as high as 85% using the challenging leave-one-video-out cross-validation scheme. The dissimilar audiovisual characteristics of the tested games showcase the strengths and limitations of the proposed method.

description: Routing quantum information among different nodes in a network is a fundamental prerequisite for a quantum internet. While single-qubit routing has been largely addressed, many-qubit routing protocols have not been intensively investigated so far. Building on the many-excitation transfer protocol in arXiv:1911.12211, we apply the perturbative transfer scheme to a two-excitation routing protocol on a network where multiple two-receivers block are coupled to a linear chain. We address both the case of switchable and permanent couplings between the receivers and the chain. We find that the protocol allows for efficient two-excitation routing on a fermionic network, although for a spin-$\frac{1}{2}$ network only a limited region of the network is suitable for high-quality routing.

description: We describe a long term project aimed at deriving information on the chemical evolution of the Galactic disk from a large sample of open clusters. The main property of this project is that all clusters are analyzed in a homogeneous way, to guarantee the robustness of the ranking in age, distance and metallicity. Special emphasis is devoted to the evolution of the earliest phases of the Galactic disk evolution, where clusters have superior reliability with respect to other types of evolution indicators. The project is twofold: on the one hand we derive age, distance and reddening (and indicative metallicity) interpreting deep and accurate photometric data with stellar evolution models, and, on the other hand, we derive the chemical abundances from high-resolution spectroscopy. Here we describe our overall goals and approaches, and report on the mid-term project status of the photometric part, with 16 clusters already studied, covering an age interval from 0.1 to 6 Gyr and Galactocentric distances from 6.6 to 21 kpc. The importance of quantifying the theoretical uncertainties by deriving the cluster parameters with various sets of stellar models is emphasized. Stellar evolution models assuming overshooting from convective regions appear to better reproduce the photometric properties of the cluster stars. The examined clusters show a clear metallicity dependence on the Galactocentric distance and no dependence on age. The tight relation between cluster age and magnitude difference between the main sequence turn off and the red clump is confirmed.

Welcome home: a life/work community in South-East False Creek, Vancouver

Publisher: name: University of British Columbia

description: The project began with a comprehensive investigation to discover and define the crucial elements of design in high density housing that foster a strong and rich sense of community. Both historical precedents and current Vancouver projects were studied to determine their attitude toward community in dense housing situations. I found the designs that were most successful in preserving a traditional sense of community demonstrated a far greater respect for one's individuality. They provided a strong frame for variable urban living, which reflects the pluralism of urban life. The program for this thesis was a live/work community and one live/work building within that planned community. The site for this exploration was South-East False Creek. The resolution of my proposal began with developing a new housing fabric, a prototype that could be used at South-East False Creek or in other areas of the city. The fabric I developed is a more intimate, finer slice of the existing Vancouver city grid. By maintaining some of the critical dimensions of Vancouver's city grid, the design of the new fabric can either fit into the existing grid or occur next to it. The community plan provides several distinct adjacencies for the buildings: live side, work side, park side and street/parking side. My concern with the design of the building was to identify a set of possibilities that are inherent in the community fabric, which show the diversity of the building itself as well as the flexibility of the space within the units.

description: In the light of project management (PM), in time and financial terms, Greek public works are characterized by certain contractual requirements, as outlined by the national legislation in force. These requirements are handled by several software applications, the most popular in big projects Primavera. The organisation procedures of the team responsible for the follow up of time and cost in local, regional and central level of administration are presented, the means available and also the procedures. Special attention is given to the procedures of project programming and how projects are homogenised so as the team is able to monitor the in a uniform way. An application of the above is given in a project under construction. In the end the conclusion about the difficulties of applying such a system in a big project and the proposals for a unified works monitoring system.

description: Redback millisecond pulsars (MSPs) typically show pronounced orbital variability in their X-ray emission due to our changing view of the intrabinary shock (IBS) between the pulsar wind and stellar wind from the companion. Some redbacks ("transitional" MSPs) have shown dramatic changes in their multiwavelength properties, indicating a transition from a radio pulsar state to an accretion-powered state. The redback MSP 47 Tuc W showed clear X-ray orbital variability in the Chandra ACIS-S observations in 2002, which were not detectable in the longer Chandra HRC-S observations in 2005-06, suggesting that it might have undergone a state transition. However, the Chandra observations of 47 Tuc in 2014-15 show similar X-ray orbital variability as in 2002. We explain the different X-ray light-curves from these epochs in terms of two components of the X-ray spectrum (soft X-rays from the pulsar, vs. harder X-rays from the IBS), and different sensitivities of the X-ray instruments observing in each epoch. However, when we use our best-fit spectra with HRC response files to model the HRC light-curve, we expect a more significant and shorter dip than that observed in the 2005-06 Chandra data. This suggests an intrinsic change in the IBS of the system. We use the ICARUS stellar modelling software, including calculations of heating by an IBS, to model the X-ray, optical, and UV light-curves of 47 Tuc W. Our best-fitting parameters point towards a high-inclination system (i~60 deg), which is primarily heated by the pulsar radiation, with an IBS dominated by the companion wind momentum.

description: In the ground state of the doped two-leg Hubbard ladder there are power-law decaying d_{x^2-y^2}-type pairing correlations. It is important to know the strength and the temperature scale of these correlations. For this purpose, we have performed determinantal Quantum Monte Carlo (QMC) calculations of the reducible particle-particle interaction in the Hubbard ladder. In this paper, we report on these calculations and show that, at sufficiently low temperatures, resonant particle-particle scattering takes place in the d_{x^2-y^2} pairing channel for certain values of the model parameters. The QMC data presented here indicate that the d_{x^2-y^2} pairing correlations are strong in the Hubbard ladder.
