Radiolabelling of organic molecules with short-lived radionuclides (¹¹C, ¹⁸F)
Creators: name: Balatoni, Julius Alexander
Publisher: name: University of British Columbia
Year: 2009

description: The primary aim of this study was to develop new methods for the introduction of short-lived radionuclides(11C, 18F) into organic molecules. This was accomplished by the use of organometallic intermediates: (i)(η6-arene)tricarbonylchromium complexes were used to facilitate aromatic nucleophilic substitution of the attached arene for the incorporation of [11C]cyanide anion, and (ii) vinyl-tin derivatives were employed for electrophilic fluorination reactions to produce 19F- and18F-labelled vinyl fluorides. A range of simple(η6-arene)tricarbonylchromium complexes were prepared as model systems. Fluorine was found to be the only leaving group that was readily displaced by cyanide. Non-radioactive and11C-labelled aryl nitriles were prepared in 10 minutes by reaction of complexes 1, 4, 5, and 6 with[12C]cyanide and[11C]cyanide in DMSO at elevated temperature. Under the reaction conditions used, the aryl nitrile product was liberated from the chromium tricarbonyl moiety thereby obviating the need for a separate oxidative decomplexation step. The reactivity of (E)-vinylstannanes 30, 31, 32, 33, and 34 was studied with elemental fluorine and acetyl hypofluorite under varied conditions. Generally, gaseous CH3COOF was found to be the most effective fluorinating agent for the electrophilic cleavage of vinyl-tin bonds. For example, 31 was fluorinated with CH3COOF, at room temperature, to yield an isomeric mixture of 39 and 40 in 41-42% yield; fluorination with F2 proceeded in 9.0% yield at best. Subsequently, 31 was radiofluorinated with CH3COO18F in 19% radiochemical yield (based on starting [18F]F2). [Scientific formulae used in this abstract could not be reproduced.

description: A continuum, post-deposition mesoscopic model of a Moiré-regulated self-assembly of metal nanoclusters on a twisted bilayer graphene is presented. Quasi-two-dimensional nanocluster-like steady states at a low adsorbate coverage are analytically determined for Pt, Ni, and Pb adsorbates, pointing that nanoclusters self-assemble at the Moiré cells centers. This is followed by the computations of nanoclusters self-assembly dynamics. Differences in the self-assembly efficiency for three chosen metals are highlighted across three typical values of an initial submonolayer coverage and for three temperature regimes. Accounting for the adsorption potential of metal atoms onto graphene leads to a significantly faster nanoclusters self-assembly and has a transient impact on the nanoclusters morphologies. A model extensions to the cases of nanoclusters self-assembly on a Moiré formed by a monolayer graphene over a metal substrate, and the electromigration-guided self-assembly on such Moiré are proposed.

description: We present here up-to-date neutrino mass limits exploiting the most recent cosmological data sets. By making use of the Cosmic Microwave Background temperature fluctuation and polarization measurements, Supernovae Ia luminosity distances, Baryon Acoustic Oscillation observations and determinations of the growth rate parameter, we are able to set the most constraining bound to date, $\sum m_ν<0.09$ eV at $95\%$~CL. This very tight limit is obtained without the assumption of any prior on the value of the Hubble constant and highly compromises the viability of the inverted mass ordering as the underlying neutrino mass pattern in nature. The results obtained here further strengthen the case for very large multitracer spectroscopic surveys as unique laboratories for cosmological relics, such as neutrinos: that would be the case of the Dark Energy Spectroscopic Instrument (DESI) survey and of the Euclid mission.

description: With an enlighting analysis, Baskaran and Grishchuk have recently shown the presence and importance of the so-called ``magnetic'' components of gravitational waves (GWs), which have to be taken into account in the context of the total response functions of interferometers for GWs propagating from arbitrary directions. In this paper more detailed angular and frequency dependences of the response functions for the magnetic components are given in the approximation of wavelength much larger than the linear dimensions of the interferometer, with a specific application to the parameters of the LIGO and Virgo interferometers. Our results agree with the work of Baskaran and Grishchuk in which it has been shown that the identification of ``electric'' and ``magnetic'' contributions is unambiguous in the long-wavelength approximation. At the end of this paper the angular and frequency dependences of the total response functions of the LIGO and Virgo interferometers are given. In the high-frequency regime the division on ``electric'' and ``magnetic'' components becomes ambiguous, thus the full theory of gravitational waves has to be used. Our results are consistent with the ones of Baskaran and Grishchuk in this case too.

description: In this paper, we study slow manifolds for infinite-dimensional evolution equations. We compare two approaches: an abstract evolution equation framework and a finite-dimensional spectral Galerkin approximation. We prove that the slow manifolds constructed within each approach are asymptotically close under suitable conditions. The proof is based upon Lyapunov-Perron methods and a comparison of the local graphs for the slow manifolds in scales of Banach spaces. In summary, our main result allows us to change between different characterizations of slow invariant manifolds, depending upon the technical challenges posed by particular fast-slow systems.

The intimate relationship between super-integrability and exact solvability is illustrated. Eigenfunctions are constructed through the action of the commuting operators. Finite dimensional representations of the quadratic algebras are thus constructed in a way analogous to that of the highest weight representations of Lie algebras.

One of the most viewed cases is the calculation of electrostatic potential and electric field in the symmetry axis of a centered ring and it has been widely studied the potential off the axis of a charged ring centered in the origin coordinate. In this work, we calculated the electrostatic potential and electric field in the $z$ axis of a non centered charged ring using elliptic integrals as an pedagogical example of the application of special functions in electromagnetism.

Studies Towards a Model ϐ-Sheet
Creators: name: Causton, Ashley Scott
Publisher: name: University of British Columbia
Year: 2009

description: The construction of de novo proteins is a long time goal of many researchers into the protein folding problem. In order to design and construct "tertiary" structure from scratch, an understanding of the forces involved in the lower levels of structure is necessary. Simple models are needed to confidently study the factors involved in stabilizing the secondary and super-secondary structure of proteins. One way in which this can be done is by template assembly. The template limits the degrees of freedom afforded to the attached peptide chains, directing them into pre-determined folding patterns. The long term aim of this project is to model (ϐ-sheets using a cyclotriveratrylene (CTV) molecule as template. The challenge in making this template-assembled synthetic protein is to covalently link six unprotected peptides to the macrocycle. Model studies, using amino acids protected at their C-terminus, were directed towards finding an efficient method that could be used for linking unprotected peptides. This was achieved by first bromoacetylating the amino terminus of the amino acid models using bromoacetyl bromide in methylene chloride with potassium carbonate as base. These functionalised amino acid models were subsequently coupled to the six hydroxyl moieties on the cyclotriveratrylene template using potassium carbonate as base in degassed dimethylformamide. Thus we have succeeded in coupling six single amino acid esters to a C T V macrocycle in a 90% yield. This represents the first model of a hexasubstituted de novo protein. To successfully nucleate the hydrogen bonding pattern associated with p-sheet formation the template must possess a suitable inter-strand distance. This was investigated by looking for the presence of an internal hydrogen bonding network between the six amino acid strands on the template. This was done using N M R and IR spectroscopy and comparing the results to those obtained for single stranded analogues. An internal hydrogen bonding network was observed, indicating the suitability of the cyclotriveratrylene macrocycle as a template for modeling (ϐ-sheets.

description: The aim of this paper is to calculate the expansion law and chemical enrichment of a supershell powered by the energetic feedback of a typical Galactic OB association at various galactocentric radii. We study then the orbits of the fragments created when the supershell breaks out and we compare their kinetic and chemical properties with the available observations of high - and intermediate - velocity clouds. We use the Kompaneets (1960) approximation for the evolution of the superbubble driven by sequential supernova explosions and we compute the abundances of oxygen and iron residing in the thin cold supershell. We assume that supershells are fragmented by means of Rayleigh-Taylor instabilities and we follow the orbit of the clouds either ballistically or by means of a hybrid model considering viscous interaction between the clouds and the extra-planar gas.Given the self-similarity of the Kompaneets solutions, clouds are always formed ~ 448 pc above the plane. If the initial metallicity is solar, the pollution from dying stars of the OB association has a negligible effect on the chemical composition of the clouds. The maximum height reached by the clouds above the plane seldom exceeds 2 kpc and when averaging over different throwing angles, the landing coordinate differs from the throwing coordinate ~ 1 kpc at most. The range of heights and [O/Fe] ratios spun by our clouds suggest us that the high velocity clouds cannot have a Galactic origin, whereas intermediate velocity clouds have kinematic properties similar to our modeled clouds but overabundance observed for the [O/Fe] ratios which can be reproduced only with initial metallicities which are too low compared for those of the Galaxy disk.

description: The honeycomb antiferromagnet under a triaxial strain is studied using the quantum Monte Carlo simulation. The strain dimerizes the exchange couplings near the corners, thus destructs the antiferromagnetic order therein. The antiferromagnetic region is continuously reduced by the strain. For the same strain strength, the exact numerical results give a much smaller antiferromagnetic region than the linear spin-wave theory. We then study the strained $XY$ antiferromagnet, where the magnon pseudo-magnetic field behaves quite differently. The $0$th Landau level appears in the middle of the spectrum, and the quantized energies above (below) it are proportional to $n^{\frac{1}{3}} (n^{\frac{2}{3}})$, which is in great contrast to the equally-spaced ones in the Heisenberg case. Besides, we find the antiferromagnetic order of the $XY$ model is much more robust to the dimerization than the Heisenberg one. The local susceptibility of the Heisenberg case is extracted by the numerical analytical continuation, and no sign of the pseudo-Landau levels is resolved. It is still not sure whether the result is due to the intrinsic problem of the numerical analytical continuation. Thus the existence of the magnon pseudo-Landau levels in the spin-$\frac{1}{2}$ strained Heisenberg Hamiltonian remains an open question. Our results are closely related to the two-dimensional van der Waals quantum antiferromagnets and may be realized experimentally.

description: Reaching the 2030 targets for the EU primary energy use (PE) and CO2eq emissions (CE) requires an accurate assessment of how different technologies perform on these two fronts. In this regard, the focus in academia is increasingly shifting from traditional technologies to electricity consuming alternatives. Calculating and comparing their performance with respect to traditional technologies requires conversion factors (CFs) like a primary energy factor and a CO2eq intensity. These reflect the PE and CE associated with each unit of electricity consumed. Previous work has shown that the calculation and use of CFs is a contentious and multifaceted issue. However, this has mostly remained a theoretical discussion. A stock-taking of how CFs are actually calculated and used in academic literature has so far been missing, impeding insight into what the contemporary trends and challenges are. Therefore, we structurally review 65 publications across six methodological aspects. We find that 72% of the publications consider only a single country, 86% apply a purely retrospective perspective, 54% apply a yearly temporal resolution, 65% apply a purely operational (instead of a life-cycle) perspective, 91% make use of average (rather than marginal) CFs, and 75% ignore electricity imports from surrounding countries. We conclude that there is a strong need in the literature for a publicly available, transparently calculated dataset of CFs, which avoids the shortcomings found in the literature. This would enable more accurate and transparent PE and CE calculations, and support the development of new building energy performance assessment methods and smart grid algorithms.

The model used is fashioned as a minimal bipartite system consisting of a trimer coupled weakly to a monomer. Semiclassical insights into the fragmentation dynamics of the condensate is obtained by mapping out the Arnold web of the high dimensional classical phase space. A remarkable one-to-one correspondence between the quantum state space in occupation number representation and the classical Arnold web in action space is observed. The relevance of dynamical tunneling for the dynamics of Fock states near resonance junctions on the Arnold web is highlighted. We also predict the possibility of manipulating the transport within the trimer subsystem due to the weak coupling to the monomer.

Topological phases and Anderson localization in off-diagonal mosaic lattices

description: We introduce a one-dimensional lattice model whose hopping amplitudes are modulated for equally spaced sites. Such mosaic lattice exhibits many interesting topological and localization phenomena that do not exist in the regular off-diagonal lattices. When the mosaic modulation is commensurate with the underlying lattice, topologically nontrivial phases with zero- and nonzero-energy edge modes are observed as we tune the modulation, where the nontrivial regimes are characterized by quantized Berry phases. If the mosaic lattice becomes incommensurate, Anderson localization will be induced purely by the quasiperiodic off-diagonal modulations. The localized eigenstate is found to be centered on two neighboring sites connected by the quasiperiodic hopping terms. Furthermore, both the commensurate and incommensurate off-diagonal mosaic lattices can host Chern insulators in their two-dimensional generalizations. Our work provides a platform for exploring topological phases and Anderson localization in low-dimensional systems.

description: Uropeltis ruhunae Deraniyagala, 1954
 As detailed by Pyron et al. (2016), Deraniyagala (1954) described Platyplectrurus ruhunae Deraniyagala, 1954 and Uropeltis ruhunae Deraniyagala, 1954 (both with type locality “Galle”) from specimens found in a jar containing snakes from both the Galle district of Sri Lanka and the Madurai district of India (De Silva 1980). Thus, origin of the holotypes from Sri Lanka is in serious doubt. While recent works (e.g., McDiarmid et al. 1999; Wallach et al. 2014) considered Platyplectrurus ruhunae Deraniyagala, 1954 to be a synonym of Platyplectrurus madurensis Beddome, 1877; Uropeltis ruhunae Deraniyagala, 1954 was still considered valid (see Wallach et al. 2014). Pyron et al. (2016:464) compared the scalation of the holotype (NMSL R.S. 52) of Uropeltis ruhunae Deraniyagala, 1954 to known populations of Uropeltis woodmasoni (Theobald, 1876), concluding that it was a member of that species. Here, we present photographs of NMSL R.S. 52 (Fig. 1), as well as photographs of two syntypes of Silybura nigra Beddome, 1878 (MNHN-RA-1895.85a–b; Figs. 2 a–d), a junior synonym of Uropeltis woodmasoni (Theobald, 1876). In addition to the lepidosis data reported by Pyron et al. (2016), visual comparisons of the dorsal and ventral color-pattern further cement this association. The holotype (ZSI 8760) of Uropeltis woodmasoni (Theobald, 1876) is in relatively poor condition, but photographs provided by I. Das are essentially identical to the nigra and ruhunae types in overall shape and remaining visible color-pattern. Specifically, hypertrophied anterior trunk musculature and “swollen” aspect of the first ~1/4 of body; irregular yellow stripe on the first several dorsal scale rows, beginning on posteriormost labials and extending ~1/4 the length of the body, dark brown dorsum with broken rings of yellow ocellations or speckles on the posteriormost ¾ of body, spaced 3-4 scale rows apart; and irregular yellow and brown zigzags or blotches on the venter, with yellow occasionally and irregularly extending on to the first few dorsal scale rows.

description: We study the dynamics of long-wavelength fluctuations in one-dimensional (1D) many-particle systems as described by self-consistent mode-coupling theory. The corresponding nonlinear integro-differential equations for the relevant correlators are solved analytically and checked numerically. In particular, we find that the memory functions exhibit a power-law decay accompanied by relatively fast oscillations. Furthermore, the scaling behaviour and, correspondingly, the universality class depends on the order of the leading nonlinear term. In the cubic case, both viscosity and thermal conductivity diverge in the thermodynamic limit. In the quartic case, a faster decay of the memory functions leads to a finite viscosity, while thermal conductivity exhibits an even faster divergence. Finally, our analysis puts on a more firm basis the previously conjectured connection between anomalous heat conductivity and anomalous diffusion.

description: В статье рассматриваются патогенетические и клинические особенности поражения мозжечка. Анализируются причины, приводящие к возникновению мозжечковых нарушений. Наиболее частой причиной повреждения мозжечка являются острые нарушения мозгового кровообращения. Детально рассматриваются механизмы возникновения дисгемических расстройств в вертебрально-базилярной артериальной системе, включая диссекцию позвоночных артерий. Приводится описание клинических особенностей поражения различных отделов мозжечка. Отмечается роль мозжечка и его связей в осуществлении когнитивных функций. Приводится описание клинических приемов и проб, помогающих выявлять мозжечковое поражение даже в легких случаях. Рассматриваются клинические особенности заболеваний головного мозга, с которыми необходимо дифференцировать цереброваскулярные расстройства, протекающие с клинической картиной мозжечковой атаксии. Оценка жалоб больного, тщательный сбор анамнеза и детальное неврологическое обследование позволяют поставить правильный топический и нозологический диагноз, но нередко дифференциальная диагностика патологических состояний, связанных с поражением мозжечка, представляет сложную проблему, в подобных случаях помогает МРТ головного мозга.

description: We study a quantum spin system on a honeycomb lattice, when it includes frustration and distortion in antiferromagnetic (AF) exchange interactions. We transform the spin system onto a nonlinear sigma model (NLSM) in a new way preserving the original spin degrees of freedom. Assisted by a renormalization- group argument, the NLSM provides a ground-state phase diagram consisting of an ordered AF phase and a disordered spin-gap phase. The spin-gap phase extends from a strong frustration regime to a strong distortion regime, showing that the disordered ground states are essentially the same in both the regimes. In the spin-half case, the spin-gap phase for the spin system on a honeycomb lattice is larger than that for the J1-J2 model on a square lattice.

description: Тревожно-депрессивные расстройства у больных инсультом, среди ряда предрасполагающих причин, значительно снижают реабилитационный потенциал, повышают риск развития экстрацеребральной патологии, что приводит к росту числа неблагоприятных функциональных и общих исходов заболевания. В статье рассмотрены механизмы патогенеза данных расстройств, ключевую роль в которых играют нарушения работы нейробиохимических структур и изменение их нейромедиаторного баланса. Дополнение стандартных методов лечения путем применения новых разработок немедикаментозного воздействия, в том числе виртуальной реальности, позволит повысить эффективность терапии постинсультных аффективных расстройств, что в свою очередь увеличит повседневную активность пациентов, способствуя восстановлению утраченных функций и улучшению качество жизни.

description: Εξαιτίας του προσφυγικού ζητήματος ένας πρωτόγνωρα μεγάλος αριθμός προσφύγων και αιτούντων ασύλου κατέφθασε στην Ελλάδα. Ανάμεσα τους μεγάλος αριθμός παιδιών που είχαν αποσπασματική ή μηδενική φοίτηση σε τυπικό εκπαιδευτικό σύστημα. Δικαίωμα όλων των παιδιών είναι η ελεύθερη πρόσβαση σε ποιοτικό εκπαιδευτικό σύστημα. Για όσο χρονικό διάστημα παραμείνουν στην Ελλάδα, δεδομένου ότι ο μεγαλύτερος αριθμός προσφύγων έχει αιτηθεί άσυλο σε άλλη ευρωπαϊκή χώρα και για όσα παιδιά τελικώς διαμείνουν αποτελεί υποχρέωση της πολιτείας η εξασφάλιση ποιοτικής φοίτησης στο εκπαιδευτικό σύστημα. Εντός του σχολικού έτους 2016-2017 πραγματοποιήθηκε η σταδιακή ένταξη των παιδιών προσφύγων στο ελληνικό εκπαιδευτικό σύστημα. Η παρούσα εργασία καταγράφει τις δράσεις της ελληνικής πολιτείας για τη δημιουργία όλων εκείνων των προϋποθέσεων για την ένταξη στο Δημοτικό Σχολείο και ερευνά το πλαίσιο και τις πρακτικές εντός του οποίου αναπτύχθηκαν. Επιπρόσθετα μελέτησε τη συμβουλευτική και επιμορφωτική υποστήριξη που είχαν οι εκπαιδευτικοί καθώς και την υποστήριξη που έτυχαν τα παιδιά πρόσφυγες κατά την ένταξη και παραμονή τους. Τέλος κατατίθενται προτάσεις για την ουσιαστική ένταξη των παιδιών προσφύγων στο ελληνικό εκπαιδευτικό σύστημα και τη βελτίωση της παρεχόμενης εκπαίδευσης.
description: Due to the immigrant issue, an immense number of refugees and asylum seekers have reached the Greek borders. Among them, there has been a large number of children with fragmentary, minimal, or non-existence attendance to a formal educational system. Free access to a qualitative educational system remains an inalienable right. Taking into consideration that the majority of refugees has already sought asylum to another country, the ensuring of a qualitative educational attendance for those children that finally remain in Greece is the Greek state's responsibility. A gradual integration of the refugee children into the Greek educational system has taken place during the last school year (2016-2017). This paper captures the actions of the Greek government to create the conditions for the integration into primary school and researches the frame and practices through which such practices were developed. Furthermore, it encapsulates the advisory and training support of both the teachers and the children in order to assist the latter with their integration. Finally, critical suggestions are proposed for an essential and substantive integration of the refugees’ children into the Greek educational system alongside with the improvement of the provided education.

description: The recent realisations of hydrogen doped $Ln$FeAsO ($Ln$=Nd and Sm) superconducting epitaxial thin films call for further investigation of their structural and electrical transport properties. Here, we report on the microstructure of a NdFeAs(O,H) epitaxial thin film and its temperature, field, and orientation dependencies of the resistivity and the critical current density $J_{\rm c}$. The superconducting transition temperature $T_{\rm c}$ is comparable to NdFeAs(O,F). Transmission electron microscopy investigation supported that hydrogen is homogenously substituted for oxygen. A high self-field $J_{\rm c}$ of over 10 MA/cm$^2$ was recorded at 5 K, which is likely to be caused by a short London penetration depth. The anisotropic Ginzburg-Landau scaling for the angle dependence of $J_{\rm c}$ yielded temperature-dependent scaling parameters $γ_{\rm J}$ that decreased from 1.6 at 30 K to 1.3 at 5 K. This is opposite to the behaviour of NdFeAs(O,F). Additionally, $γ_{\rm J}$ of NdFeAs(O,H) is smaller than that of NdFeAs(O,F). Our results indicate that heavily electron doping by means of hydrogen substitution for oxygen in $Ln$FeAsO is highly beneficial for achieving high $J_{\rm c}$ with low anisotropy without compromising $T_{\rm c}$, which is favourable for high-field magnet applications.

description: We introduce a modified version of a standard power spectrum `peak-bagging' technique which is designed to gain some of the advantages that fitting the entire low-degree p-mode power spectrum simultaneously would bring, but without the problems involved in fitting a model incorporating many hundreds of parameters. Employing Monte-Carlo simulations we show that by using this modified fitting code it is possible to determine the true background level in the vicinity of the p-mode peaks. In addition to this we show how small biases in other mode parameters, which are related to inaccurate estimates of the true background, are also consequently removed.

description: Побочные эффекты антигельминтного и иммуномодулирующего препарата левамизол начали описывать в 90-х годах прошлого столетия. Одним из редких побочных действий является левамизол-индуцированная лейкоэнцефалопатия. Представленный клинический случай является ярким доказательством сложности диагностики и определения тактики лечения данного заболевания. У больной в течение нескольких дней после самостоятельного приема левамизола развились такие симптомы, как нарушение речи, полный отказ от приема пищи, общая слабость. Диффузная лейкоэнцефалопатия подтвердилась проведенной магнитно-резонансной томографией (МРТ). Пациентке была назначена глюкокортикостероидная, противоотечная, антиоксидантная, ноотропная, диуретическая терапия, проводился плазмаферез. Симптоматика начала регрессировать после 2 мес., проведенных в стационаре: полностью восстановилась речь, бульбарные нарушения регрессировали, восстановлено глотание. В связи с положительной динамикой пациентка была выписана домой под наблюдение врачей по месту жительства.

description: Forecasting the particulate matter (PM) concentration in South Korea has become urgently necessary owing to its strong negative impact on human life. In most statistical or machine learning methods, independent and identically distributed data, for example, a Gaussian distribution, are assumed; however, time series such as air pollution and weather data do not meet this assumption. In this study, the maximum correntropy criterion for regression (MCCR) loss is used in an analysis of the statistical characteristics of air pollution and weather data. Rigorous seasonality adjustment of the air pollution and weather data was performed because of their complex seasonality patterns and the heavy-tailed distribution of data even after deseasonalization. The MCCR loss was applied to multiple models including conventional statistical models and state-of-the-art machine learning models. The results show that the MCCR loss is more appropriate than the conventional mean squared error loss for forecasting extreme values.
