A molecular thermodynamic model for chiral drug purification using chiral ligand exchange chromatography
Creators: name: Sanaie, Nooshafarin
Publisher: name: University of British Columbia
Year: 2010

description: NR-20081 Chiral ligand exchange chromatography (CLEC) separates enantiomers of alkaloids, amino and carboxylic acids, barbiturates, β-blockers and other adrenergic drugs. It relies on subtle energetic differences between ternary homo- and hetero-chiral complexes formed between a ligand capable of chelating a divalent transition-metal ion and an enantiomer. CLEC separation efficiency is strongly dependent on column operating conditions, including pH, temperature, mobile-phase composition, and feed composition. Each enantiomer participates in a large number of solution and stationary-phase complexes within the column. As a result, the mechanism of separation is complex and poorly understood, making it difficult to identify optimal column operating conditions using conventional empirical strategies. A new model for CLEC-based separations is presented that provides a molecular understanding of the separation process. It combines the non-ideal equilibrium dispersion model of chromatography with multiple chemical equilibria theory to accurately predict enantiomer transport and partitioning, elution band profiles, and separation efficiency over a wide range of permissible column operating conditions. Mass transport parameters are determined by moment analysis and used to show that solute mass transfer and binding is limited by pore diffusion during separation of α-amino acid racemates on a Nucleosil Chiral-1 column (bearing a L-hydroxyproline as the chiral selector) or of dopa enantiomers on a Chirex 3126 column (bearing a derivative of D-penicillamine as the chiral selector). As a result, the local equilibrium approximation can be applied at all standard column operating conditions. Stoichiometries and formation constants for all equilibrium complexes formed in the column are taken from standard thermodynamic databases or independent potentiometric titration experiments. Model performance is assessed through comparison with chromatograms for hydrophobic amino-acid racemates loaded on a Nucleosil Chiral-1 CLEC column. The model is then applied to a medically relevant separation: the resolution of dopa enantiomers on a Chirex 3126 CLEC column. In both cases, the model is shown to provide an accurate and detailed picture of the separation process useful for elucidating the mechanism of separation and the associated influence of key column operating variables on speciation profiles. Finally, the model is successfully applied to a restricted optimization of column operating conditions for the separation of D,L-valine, indicating that it may provide a rapid and comprehensive path to process optimization.

description: We present new results of a deep optical imaging survey using a narrowband filter ($NB921$) centered at $λ=$ 9196 Å~ together with $B$, $V$, $R$, $i^\prime$, and $z^\prime$ broadband filters in the sky area of the Subaru Deep Field which has been promoted as one of legacy programs of the 8.2m Subaru Telescope. We obtained a photometric sample of 58 Ly$α$ emitter candidates at $z \approx$ 6.5 -- 6.6 among $\sim 180$ strong $NB921$-excess ($z^\prime - NB921 > 1.0$) objects together with a color criterion of $i^\prime - z^\prime > 1.3$. We then obtained optical spectra of 20 objects in our $NB921$-excess sample and identified at least nine Ly$α$ emitters at $z \sim 6.5$ -- 6.6 including the two emitters reported by Kodaira et al. (2003). Since our Ly$α$ emitter candidates are free from strong amplification of gravitational lensing, we are able to discuss their observational properties from a statistical point of view. Based on these new results, we obtain a lower limit of the star formation rate density of $ρ_{\rm SFR} \simeq 5.5 \times 10^{-4}$ $h_{0.7}$ $M_\odot$ yr$^{-1}$ Mpc$^{-3}$ at $z \approx 6.6$, being consistent with our previous estimate. We discuss the nature of star-formation activity in galaxies beyond $z=6$.

description: The 2-dimensional Ising model on a square lattice is investigated with a variational autoencoder in the non-vanishing field case for the purpose of extracting the crossover region between the ferromagnetic and paramagnetic phases. The encoded latent variable space is found to provide suitable metrics for tracking the order and disorder in the Ising configurations that extends to the extraction of a crossover region in a way that is consistent with expectations. The extracted results achieve an exceptional prediction for the critical point as well as agreement with previously published results on the configurational magnetizations of the model. The performance of this method provides encouragement for the use of machine learning to extract meaningful structural information from complex physical systems where little a priori data is available.

description: Cold-chain has colloquially been interpreted as cold warehousing, and primarily equated as yet another medium to store surplus agricultural produce, to meet delayed or deferred. Whereas this model may be applicable for a small range of perishable produce, the far larger opportunity from cold-chain arises when it is applied as a dynamic integration of a chain of logistics activities, to expand the selling range of perishable produce. This paper discusses these aspects from the Indian perspective, with special focus on fresh horticultural produce. The discussions emphasise the role of cold-chain logistics, and how it serves as an enabler for improving the efficiency of agriculture. The paper explains the untapped opportunity of using cold-chain to connect farm output with wider markets, instead of merely using cold warehousing to build inventory waiting for local demand to resurface.

description: Die Rowhammer-Schwachstelle stellt ein drastisches Sicherheitsrisiko für moderne Computersysteme dar. Bösartige Angreifer können damit gezielt Daten manipulieren bzw. Kontrolle über ganze Computersysteme erlangen, indem sie Daten ohne jegliche Autorisierung modifizieren. Die vorliegende Arbeit analysiert die öffentlich bekannten Rowhammer-Angriffe auf Betriebssysteme und präsentiert erstmals eine alternative, auf Softwarediversität beruhende Lösung für dieses Problem. Da die bekannten Angriffe stets auf der Vorhersagbarkeit von in modernen Betriebssystemen eingesetzten Algorithmen basieren, beabsichtigen wir, diese Vorhersagbarkeit mittels Softwarediversität zu unterbinden. In concreto stellen wir Page Sacrifice vor: eine leicht umzusetzende, effiziente Modifikation bestehender Mechanismen, die Rowhammer Angriffe verhindert, indem bei jeder Speicherzuweisung physisch benachbarte Speicherblöcke zufällig freigelassen und somit Speicherzuweisungen unvorhersehbar werden. Der Speicher wird dadurch allerdings nicht dauerhaft belegt sobald das Betriebssystem einen Speicherblock wieder frei gibt, werden auch die freigelassenen Blöcke wieder verfügbar. Um unsere Verteidigungsmaßnahme zu evaluieren, wurde ein Prototyp für Linux entwickelt, der anhand weitverbreiteter Messmethoden untersucht wurde. page sacrifice stellt eine neue Maßnahme gegen Rowhammer-Angriffe dar.
description: The Rowhammer vulnerability allows the modification of arbitrary data without authorization. This poses a dramatic security risk for modern computing systems, as it allows malicious attackers to manipulate data or even gain the control over entire systems. This thesis analyzes publicly available attacks based on Rowhammer as well as known defenses against them. Finally, it suggests a novel solution to the problem based on software diversity. As existing attacks are typically based on the predictability of algorithms used in modern operating systems, we aim to prevent these predictability using software diversity. In concreto we present page sacrifice, an easy-to-implement, efficient modification of existing operating system mechanisms which prevents Rowhammer attacks by making the locations of memory blocks unpredictable. This is done by randomly leaving neighboring blocks free when memory is allocated. Leaving memory blocks free does not mean that they remain occupied: As soon as the operating system frees a memory block, it also frees the blocks which were left empty during the memory allocation. To evaluate our defense, we implemented a prototype for Linux which we evaluated using widely known benchmarks. page sacrifice is a new defense against Rowhammer based attacks.

description: Topological constraints (TCs) between polymers determine the behaviour of complex fluids such as creams, oils and plastics. Most of the polymer solutions used every day life employ linear chains; their behaviour is accurately captured by the reptation and tube theories which connect microscopic TCs to macroscopic viscoelasticity. On the other hand, polymers with non-trivial topology, such as rings, hold great promise for new technology but pose a challenging problem as they do not obey standard theories; additionally, topological invariance -- i.e. the fact that rings must remain unknotted and unlinked if prepared so -- precludes any serious analytical treatment. Here we propose an unambiguous, parameter-free algorithm to characterise TCs in polymeric solutions and show its power in characterising TCs of entnagled rings. We analyse large-scale molecular dynamics (MD) simulations via persistent homology, a key mathematical tool to extract robust topological information from large datasets. This method allows us to identify ring-specific TCs which we call "homological threadings" (H-threadings) and to connect them to the polymers' behaviour. It also allows us to identify, in a physically appealing and unambiguous way, scale-dependent loops which have eluded precise quantification so far. We discover that while threaded neighbours slowly grow with the rings' length, the ensuing TCs are extensive also in the asymptotic limit. Our proposed method is not restricted to ring polymers and can find broader applications for the study of TCs in generic polymeric materials.

description: Az ökológiai gazdálkodás költség-jövedelem viszonyait a hagyományos termeléssel összehasonlítva, modellszámítások alapján vizsgáltuk. A modellépítéshez szükséges adatokat Hortobágy térségében működő egyéni gazdálkodók körében gyűjtöttünk. Az egy hektárra jutó költségek összegében a két gazdálkodási mód között jelentőseltérések nem voltak, a költségek szerkezete azonban markáns különbségeket mutatott, amely a technológiák eltéréseivel magyarázható. Az ökológiai növénytermelésben a hozamok jellemzően alacsonyabbak voltak, az önköltség és az értékesítési árak viszont magasabbak. Egyik termelési mód sem bizonyult életképesnek támogatások nélkül, a bruttó jövedelem különbségeit azonban nem a támogatások, hanem elsősorban az eltérő hozamok és értékesítési árak magyarázták. A modellváltozatok többségében az ökológiai gazdálkodás jövedelmezőbb, de az ezt biztosító „ökofelár” – a szakirodalomból ismert tendenciáknak megfelelően – már nem minden évben elegendő a magasabb jövedelem eléréséhez. Mivel az ökológiai gazdálkodás árelőnye csökken, e termelési mód jövedelemhelyzetét egyre inkább a kiegyensúlyozott hozamok, a hagyományos gazdálkodáshoz viszonyított hozamhátrány mérséklése határozza meg a közeljövőben. --------------------------------------- The costs of and income from ecological farming in comparison with traditional farming was examined on the basis of model calculations. The data used for building the model were collected from farmers working in the Hortobágy region. No significant differences were found in terms of the per hectare cost of the two farming methods. There were very visible differences in the cost structure, however, which is explained by the differences between the technologies used. In ecological crop farming, yields tended to be lower, while production cost and sale prices were higher. Neither farming approach was found to be viable without subsidies. The variation in gross income, however, was due primarily to differences in yield and sale prices rather than to the subsidies. In most versions of the model, ecological farming was more profitable, but - in line with the trends described in the relevant literature - the underlying ‘eco premium is not sufficient for achieving a higher income every year. As the price advantage of ecological farming is declining, the level of income from this farming methodology will in the close future be determined more by balanced yields and by reducing the difference in yields as compared to traditional farming.

description: Single, rf-trapped ions find various applications ranging from metrology to quantum computation. High-resolution interrogation of an extremely weak transition under best observation conditions requires an ion almost at rest. To avoid line-broadening effects such as the second order Doppler effect or rf heating in the absence of laser cooling, excess micromotion has to be eliminated as far as possible. In this work the motional state of a confined three-level ion is probed, taking advantage of the high sensitivity of observed dark resonances to the trapped ion's velocity. Excess micromotion is controlled by monitoring the dark resonance contrast with varying laser beam geometry. The influence of different parameters such as the cooling laser intensity has been investigated experimentally and numerically.

For the quark sector, we employ the MIT bag model, as well as the Nambu--Jona-Lasinio (NJL) and the Color Dielectric (CD) models, and find that the NS maximum masses lie in the interval between 1.5 and 1.8 solar masses.

Primary data were collected from a total of 110 migrants using two staged purposive sampling procedure. The data were analysed using descriptive statistics and Foster, Greer and Thorbecke poverty analysis method. The results showed that the average sampled migrants were about 41 years old. Majority of them were male, married and literate. Majority of them had household size of between 6 and 10 members. The study underlined the rural push, owing to low level of income as a major determinant for the process of migration. The possibility of getting job in Tedun was highest for migrants than in any other town in the study area. The period of waiting for job was lowest in Tedun and highest in Agoo than in any other town in the study area. Getting jobs through friends and relatives as sources of employment was highest in Tedun and Nigerb. The study revealed that, low income and better standard of living were the major factors causing migration in the study area.

description: This study profiled and decomposed political inequality among rural households in Nigeria. Core welfare indicator questionnaire survey data conducted by National Bureau of Statistics in 2006 was used. The data was analyzed using Generalized Entropy and Shapley decomposition. Result revealed that 90.8% of the respondents have low participatory ratio in politics and decision making and the level of dispersion across the mean of the population share is 0.196. South East and North Central zone have the highest (0.217) and the least (0.195) level of dynamics. Shapley decomposition shows that political inequality is more as a result of dynamics within the various socio-economic groups contributing between 94.8% and 98.2% of the total political inequality. Furthermore, households that are headed by male, have household size consisting of 6-10 members, 31-60 years. Low level of participation in politics and decision making therefore calls for political reform by all stakeholders and development partners to remove violence, corruption and rigging from the political system and also to sensitize households on the importance of participation in politics and decision making in the policy formulation and implementation processes.

description: Quaternion space has brought several benefits over the traditional Euclidean space: Quaternions (i) consist of a real and three imaginary components, encouraging richer representations; (ii) utilize Hamilton product which better encodes the inter-latent interactions across multiple Quaternion components; and (iii) result in a model with smaller degrees of freedom and less prone to overfitting. Unfortunately, most of the current recommender systems rely on real-valued representations in Euclidean space to model either user's long-term or short-term interests. In this paper, we fully utilize Quaternion space to model both user's long-term and short-term preferences. We first propose a QUaternion-based self-Attentive Long term user Encoding (QUALE) to study the user's long-term intents. Then, we propose a QUaternion-based self-Attentive Short term user Encoding (QUASE) to learn the user's short-term interests. To enhance our models' capability, we propose to fuse QUALE and QUASE into one model, namely QUALSE, by using a Quaternion-based gating mechanism. We further develop Quaternion-based Adversarial learning along with the Bayesian Personalized Ranking (QABPR) to improve our model's robustness. Extensive experiments on six real-world datasets show that our fused QUALSE model outperformed 11 state-of-the-art baselines, improving 8.43% at HIT@1 and 10.27% at NDCG@1 on average compared with the best baseline.

description: Serbia has extraordinary conditions for considerably bigger herbal and livestock organic production. The constant growth of the demand for the organic products in the world points to the fact that this method of production can be extremely profitable if natural resources, knowledge and productive experience are used in the right way. Most of natural meadows and pastures in Serbia are situated in hilly and mountainous areas. Agricultural activities were extinguished due to the depopulation trend. Therefore the development of intensive production wasn’t achieved. The aim of this paper is to point out the possibility and perspective of livestock development, according to the existing conditions, and the necessity of realization of planned investment programs on the state level. Also, its aim is to underline the possibility of development of organic production in rural areas. Considering the preservation of nature and existing economic aspect, there are possibilities for organic production of meat, milk and dairies. The results of statistic data of livestock fund are also presented in this paper, as well as percentile share of meadow and pasture participation in total usage of agricultural areas in the counties of the Republic of Serbia. The Law of organic production and related regulations were adopted by the state and subsidies for the production of this type were given as well. The result was that first producers were converted to this kind of agricultural production. Also, the analyzed state of organic livestock production in the world and Europe (EU) points to the institutional and natural conditions for the organic development in Serbia, and to the basic recommendations for its development.

description: Mammalian cells are being increasingly used to manufacture complex therapeutic proteins given their ability to properly fold and glycosylate these proteins. However, protein yields are low and process enhancements are necessary to ensure economically viable processes. Methods for yield improvement, bioprocess development acceleration and rapid quantification and monitoring of cell metabolism were investigated in this study. Recognizing the adverse effect of high PCO₂ on cell growth, metabolism and protein productivity, a novel PCO₂ reduction strategy based on NaHCO₃ elimination was investigated that decreased PCO₂ by 65-72%. This was accompanied by 68-123% increases in growth rate and 58-92% increases in productivity. To enable rapid and robust data analysis from early stage process development experiments, logistic equations were used to effectively describe the kinetics of batch and fed-batch cultures. Substantially improved specific rate estimates were obtained from the logistic equations when compared with current modeling approaches. Metabolic flux analysis was used to obtain quantitative information on cellular metabolism and the validity of using the balancing method for flux estimation was verified with data from isotope tracer studies. Error propagation from prime variables into specific rates and metabolic fluxes was quantified using Monte-Carlo analysis which indicated 8-22% specific rate error for 5-15% error in prime variable measurement. While errors in greater metabolic fluxes were similar to those in the corresponding specific rates, errors in the lesser metabolic fluxes were extremely sensitive to greater specific rate errors such that lesser fluxes were no longer representative of cellular metabolism. The specific rate to metabolic flux error relationship could be accurately described by the corresponding normalized sensitivity coefficient. A framework for quasi-real-time estimation of metabolic fluxes was proposed and implemented to serve as a bioprocess monitoring and early warning system. Methods for real-time oxygen uptake and carbon dioxide production rate estimation were developed that enabled rapid flux estimation. This framework was used to characterize cellular response to pH and dissolved oxygen changes in a process development experiment and can readily be applied to a manufacturing bioreactor. Overall, the approaches for protein productivity enhancement and rapid metabolism monitoring developed in this study are general with potential for widespread application to laboratory and manufacturing-scale perfusion and fed-batch mammalian cell cultivations.

description: Propagation of backward magnetostatic surface spin waves (SWs) in exchange coupled Co/FeNi bilayers are studied by using Brillouin light scattering (BLS) technique. Two types of SWs modes were identified in our BLS measurements. They are magnetostatic surface waves (MSSWs) mode and perpendicular standing spin waves (PSSWs) mode. The dispersion relations of MSSWs obtained from the Stokes and Anti-Stokes measurements display respectively positive and negative group velocities. The Anti-Stokes branch with positive phase velocities and negative group velocities, known as backward magnetostatic surface mode originates from the magnetostatic interaction of the bilayer. The experimental data are in good agreement with the theoretical calculations. Our results are useful for understanding the SWs propagation and miniaturizing SWs storage devices.

description: Using archival spectral-imaging data with a total exposure of $\sim144$ ks obtained by {\it Chandra}, 43 X-ray sources are detected within the half-light radius of globular cluster M62 (NGC6266). Based on the X-ray colour-luminosity diagram or the positional coincidences with known sources, we have classified these sources into different groups of compact binaries including cataclysmic variable (CV), quiescent low mass X-ray binary (qLMXB), millisecond pulsar (MSP) and black hole (BH). Candidates of the X-ray counterparts of 12 CVs, 4 qLMXBs, 2 MSPs and 1 BH are identified in our analysis. The data used in our analysis consist of two frames separated by 12 years, which enable us to search for the long-term variability as well as the short-term X-ray flux variability within each observation window. Evidence for the short-term variability and long-term variability have been found in 7 and 12 sources respectively. For a number of bright sources with X-ray luminosities $L_{x}\gtrsim 10^{32}$~erg/s, we have characterized their spectral properties in further details. By comparing the X-ray population in M62 with those in several other prototypical globular clusters, we found the proportion of bright sources is larger in M62 which can possibly be a result of their active dynamical formation processes.

description: We investigate a lattice-fluid model of water, defined on a three-dimensional body centered cubic lattice. Model molecules possess a tetrahedral symmetry, with four equivalent bonding arms, aiming to mimic the formation of hydrogen bonds. The model is similar to the one proposed by Roberts and Debenedetti [J. Chem. Phys. 105, 658 (1996)], simplified in that no distinction between bond "donors" and "acceptors" is imposed. Bond formation depends both on orientation and local density. In the ground state, we show that two different ordered (ice) phases are allowed. At finite temperature, we analyze homogeneous phases only, working out phase diagram, response functions, the temperature of maximum density locus, and the Kauzmann line. We make use of a generalized first order approximation on a tetrahedral cluster. In the liquid phase, the model exhibits several anomalous properties observed in real water. In the low temperature region (supercooled liquid), there are evidences of a second critical point and, for some range of parameter values, this scenario is compatible with the existence of a reentrant spinodal.

description: Older adults, people with chronic conditions, the disabled, and people with mobility impairments suffer from movement difficulties and have the risk of falling. Mobility aids alleviate the impact of mobility limitations or improve independence and reduce the burden of care and help people with mobility problems to move around enjoy greater freedom and independence. These assistive devices are essential to facilitate more movement independence and reduce pain and boost self-confidence and happiness in the regular life of the elderly. In this review paper, we have addressed the context and need for mobility aids. The main objective of the research was to explore different options of mobility assistive devices and compare their advantages and drawbacks. The study found standard cane as the most popular assistive device of all due to its user convenience. This study can help to find out the limitations of different mobility aids and help to improve features to increase user convenience.

description: Besides it represents a support to sustainable development, organic agriculture represents also a driving force of rural development for sixty years, especially in marginal areas. As it bases on the principles of natural resources' sustainable use, protects the population health and leads to an economic strengthening of rural areas, the organic agriculture can be successfully related to rural areas' sustainable development concept, which was the goal of the paper. The paper was structured in three parts. In the first part was discussed on the sustainable development concept, from the aspect of sustainable agro-rural development catalyst. In the second part of the paper was pointed out to the concept of agrarian policy in the European Union, which was having a mutual effect on pressing forward the organic production and sustainable development during last years. Then was given a review of the structure in the Republic of Serbia, through it came to a conclusion that our country did not have satisfying rural economy, while the economic structure depended a lot from the primary sector, which has been still based on the primary resources' exploitation and high rate of poor rural population. In the third part of the paper was given the analysis of areas under the organic production in the world, and then was presented a proportion of these areas in some countries of the European Union, and finally was given the review of the state in the Republic of Serbia. As the conclusion imposes a fact that, in Serbia, cannot be expected yet more intensive increase of the organic production, although we dispose with significant natural resources, while the limits of its serious implementation are present on several levels, mentioned in this paper. However, joining the European Union would provide the conditions for activating the existing capacities and development of rural areas, based on sustainability principle.
