Studies of noncovalent complexes of Cex and its inhibitors by mass spectrometry
Creators: name: Tešić, Milica
Publisher: name: University of British Columbia
Year: 2011

description: Tandem mass spectrometry (MS/MS) has been used to compare gas phase and solution binding of three small-molecule inhibitors to the wild type and three mutant forms of the catalytic domain of Cex, an enzyme that hydrolyses xylan. The inhibitors, xylobiosyl-deoxynojirimycin, xylobiosyl-isofagomine lactam, and xylobiosyl-isofagomine consist of a common distal xylose linked to different proximal aza-sugars. The three mutant forms of the enzyme: Asn44Ala, Gln87Met and Gln87Tyr, alter the binding interactions between Cex and the distal sugar of each inhibitor. An electrospray ionization (ESI) triple quadrupole MS/MS system is used to measure the internal energies, ΔE[sub int], that must be added to gas phase ions to cause dissociation of the noncovalent enzyme-inhibitor complexes. Collision cross sections of ions of the apo-enzyme and enzyme-inhibitor complexes, which are required for the calculations of ΔE[sub int], have also been measured. The results show that, in the gas phase, enzyme-inhibitor complexes have more compact, folded conformations than the corresponding apo-enzyme ions. With the mutant enzymes the effects of substituting a single residue can be detected. The energies required to dissociate the gas phase complexes follow the same trend as the values of ΔG[sup 0/sub dissociation] in solution. This trend is observed both with different inhibitors, which probe binding to the proximal sugar, and with mutants of Cex, which probe binding to the distal sugar. Thus the gas phase complexes appear to retain much of their solution binding characteristics. Hydrogen/deuterium exchange shows that apo-protein ions from solutions of complexes exchange more hydrogens than ions of enzyme-inhibitor complexes from the same solution, indicating a more open conformation of apo-protein ions.

description: Carbon containing molecules in cold molecular clouds show various levels of isotopic fractionation through multiple observations. To understand such effects, we have developed a new gas-grain chemical model with updated 13C fractionation reactions (also including the corresponding reactions for 15N, 18O and 34S). For chemical ages typical of dense clouds, our nominal model leads to two 13C reservoirs: CO and the species that derive from CO, mainly s-CO and s-CH3OH, as well as C3 in the gas phase. The nominal model leads to strong enrichment in C3, c-C3H2 and C2H in contradiction with observations. When C3 reacts with oxygen atoms the global agreement between the various observations and the simulations is rather good showing variable 13C fractionation levels which are specific to each species. Alternatively, hydrogen atom reactions lead to notable relative 13C fractionation effects for the two non-equivalent isotopologues of C2H, c-C3H2 and C2S. As there are several important fractionation reactions, some carbon bearing species are enriched in 13C, particularly CO, depleting atomic 13C in the gas phase. This induces a 13C depletion in CH4 formed on grain surfaces, an effect that is not observed in the CH4 in the solar system, in particular on Titan. This seems to indicate a transformation of matter between the collapse of the molecular clouds, leading to the formation of the protostellar disc, and the formation of the planets. Or it means that the atomic carbon sticking to the grains reacts with the species already on the grains giving very little CH4.

description: Gamma - Iron Oxide prepared by sol -gel process was used to produce nanocomposites with polyaniline of varying aniline concentrations. TEM shows the presence of chain like structure for lower polyaniline concentration. The room temperature hysteresis curves show finite coercivity of 160 Oe for all the composites while the saturation magnetization was found to decrease with increasing polymer content. ZFC - FC magnetisation measurements indicate high blocking temperatures. It is believed that this indicates a strongly interacting system, which is also shown by our TEM results. Monte Carlo simulations performed on a random anisotropy model with dipolar and exchange inteactions match well with experimental results.

description: In 2010, the CSO has altered the definition of a farm. As a result of this change, there are some research problems, arising from a significant decrease in the number of farms that meet the new definition. One of them is the impact of this decline on the regional differentiation of economic size (EC) of individual farms. The aim of the paper was to evaluate the impact of this decrease on the regional differentiation of economic size of farms. The analysis covered the year 2010. It is the only year, for which data about the number of farms that meet both the old one and the new definition, are available. Based on CSO data, for both definitions and for each province the economic size of average private farm were estimated. Upon the results of the estimation, the ranking of regions was created. The provinces were also classified and divided into groups. As it was proved in the study, the change in the definition has significantly affected the regional diversification of economic size. Although ranking of provinces was only slightly altered, the change of the definition substantially influenced the results of dividing provinces into groups, regardless of the method of clustering.

description: Title: Comparison between the Λ\LambdaΛCDM Model and the Unified Theory of Informational Spin (TGU) with ϵ(r)−12\epsilon(r)^{-12}ϵ(r)−12 using Type Ia Supernovae

Abstract:This study presents a comparative analysis between the standard Λ\LambdaΛCDM cosmological model and the Unified Theory of Informational Spin (TGU) incorporating the coherence factor ϵ(r)−12\epsilon(r)^{-12}ϵ(r)−12. Using observational data from Type Ia supernovae, we demonstrate that the refined TGU model provides a significantly superior fit compared to Λ\LambdaΛCDM. The analysis includes a detailed statistical evaluation using Mean Squared Error (MSE) and reduced chi-squared (χ2\chi^2χ2), showing that the TGU model can explain cosmic expansion without the need for dark energy. These findings suggest that informational coherence plays a crucial role in large-scale cosmology.

description: Os preços praticados no mercado de energia elétrica, de fontes renováveis, não viabilizam plantas de biogás de última geração. Por isso, os modelos de plantas de biogás mais difundidos no Brasil são desprovidos de alta tecnologia. O biogás é uma fonte alternativa de energia que não depende apenas da geração de energia elétrica para a viabilização do investimento. Portanto, é pertinente que se faça uma análise comparativa entre diferentes cenários de mercado, para o biogás, com o objetivo de determinar quais deles poderiam ser estimulados e apoiados por programas governamentais específicos para este setor. Este trabalho analisa a viabilidade econômica de plantas de biogás, modelo europeu, para os mercados de biogás de cozinha, autoconsumo de energia elétrica e mercado livre de energia. Este estudo mostra que plantas de biogás, com tecnologia de última geração, são viáveis também no Brasil. Mas é preciso criar Normas e Legislação pertinente a cada nicho de mercado.

description: Here, we report the synthesis and magnetic properties of a Yb-based triangular-lattice compound LiYbS$_2$. At low temperatures, it features an effective spin-$\frac{1}{2}$ state due to the combined effect of crystal electric field and spin orbit coupling. Magnetic susceptibility measurements and $^7$Li nuclear magnetic resonance experiments reveal the absence of magnetic long range ordering down to 2~K, which suggests a possible quantum spin liquid ground state. A dominant antiferromagnetic nearest neighbour exchange interaction $J/k_{\rm B}\simeq$ 5.3~K could be extracted form the magnetic susceptibility. The NMR linewidth analysis yields the coupling constant between the Li nuclei and Yb$^{3+}$ ions which was found to be purely dipolar in nature.

We find that exposure to these social engagement signals increases the vulnerability of users to misinformation. This finding has important implications for the design of social media interactions in the misinformation age. To reduce the spread of misinformation, we call for technology platforms to rethink the display of social engagement metrics. Further research is needed to investigate whether and how engagement metrics can be presented without amplifying the spread of low-credibility information.

description: Coronavirus Disease 2019 (COVID-19) is an emerging respiratory disease caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) with rapid human-to-human transmission and a high case fatality rate particularly in older patients. Due to the exponential growth of infections, many healthcare systems across the world are under pressure to care for increasing amounts of at-risk patients. Given the high number of infected patients, identifying patients with the highest mortality risk early is critical to enable effective intervention and optimal prioritisation of care. Here, we present the COVID-19 Early Warning System (CovEWS), a clinical risk scoring system for assessing COVID-19 related mortality risk. CovEWS provides continuous real-time risk scores for individual patients with clinically meaningful predictive performance up to 192 hours (8 days) in advance, and is automatically derived from patients' electronic health records (EHRs) using machine learning. We trained and evaluated CovEWS using de-identified data from a cohort of 66430 COVID-19 positive patients seen at over 69 healthcare institutions in the United States (US), Australia, Malaysia and India amounting to an aggregated total of over 2863 years of patient observation time. On an external test cohort of 5005 patients, CovEWS predicts COVID-19 related mortality from $78.8\%$ ($95\%$ confidence interval [CI]: $76.0$, $84.7\%$) to $69.4\%$ ($95\%$ CI: $57.6, 75.2\%$) specificity at a sensitivity greater than $95\%$ between respectively 1 and 192 hours prior to observed mortality events - significantly outperforming existing generic and COVID-19 specific clinical risk scores. CovEWS could enable clinicians to intervene at an earlier stage, and may therefore help in preventing or mitigating COVID-19 related mortality.
Time Reversal for elastic scatterer location from Acoustic Recording

Subjects: subject: Numerical Analysis (math.NA)

description: The aim of this paper is to study the feasibility of time-reversal methods in a non homogeneous elastic medium, from data recorded in an acoustic medium. We aim to determine, from partial aperture boundary measurements, the presence and some physical properties of elastic unknown "inclusions", i.e. not observable solid objects, located in the elastic medium. We first derive a variational formulation of the acousto-elastic problem, from which one constructs a time-dependent finite element method to solve the forward, and then, the time reversed problem. Several criteria, derived from the reverse time migration framework, are then proposed to construct images of the inclusions, and to determine their locations. The dependence/sensitivity of the approach to several parameters (aperture, number of sources, etc.) is also investigated. In particular, it is shown that one can differentiate between a benign and malignant close inclusions. This technique is fairly insensitive to noise in the data.

Comparison of the Unified Informational Spin Theory-TGU with the ΛCDM Model

description: Title: Comparison of the Unified Informational Spin Theory (TGU) with the Λ\LambdaΛCDM Model: An Approach Based on Three Experiments

Abstract:This paper investigates the potential of the Unified Informational Spin Theory (TGU) as an alternative to the Λ\LambdaΛCDM model, aiming to describe gravitational phenomena without the need for dark matter. The study employs three experiments to compare the two models:

Cosmic Structures – Examining the gravitational stability of the Hercules–Corona Borealis Great Wall.

Planetary System Dynamics – Analyzing orbital period predictions for TRAPPIST-1 and Kepler-90.

Gravitational Lensing – Comparing Einstein radii predictions in gravitational lensing systems.

The results demonstrate that TGU accurately models large-scale cosmic structures, planetary orbits, and gravitational lensing effects without invoking dark matter. Instead, it explains these phenomena through informational coherence, a concept that replaces the need for unseen mass. Statistical analysis shows that TGU predictions align closely with observational data, often outperforming Λ\LambdaΛCDM, especially in planetary system dynamics.

The study concludes that TGU provides a viable alternative to the standard cosmological model, redefining gravitational interactions through informational structures. Future research will further test this approach with observational data and explore its broader astrophysical applications.

Ring dynamics around an oblate body with an inclined satellite: The case of Haumea

Publisher: name: arXiv
Year: 2020
Subjects: subject: Earth and Planetary Astrophysics (astro-ph.EP)
subject: FOS: Physical sciences

description: The recent discovery of rings and massive satellites around minor bodies and dwarf planets suggests that they may often coexist, as for example around Haumea. A ring perturbed by an oblate central body and by an inclined satellite may disperse on a short timescale. The conditions under which a ring may survive are explored both analytically and numerically. The trajectories of ring particles are integrated under the influence of the gravitational field of a triaxial ellipsoid and (a) massive satellite(s), including the effects of collisions. A ring initially formed in the equatorial plane of the central body will be disrupted if the satellite has an inclination in the Kozai Lidov regime (39.2 < i < 144.8). For lower inclinations, the ring may relax to the satellite orbital plane thanks to an intense collisional damping. On the other hand, a significant J2 term easily suppresses the perturbations of an inclined satellite within a critical semimajor axis, even in the case of Kozai Lidov cycles. However, if the ring is initially inclined with respect to the equatorial plane, the same J2 perturbations are not a protective factor but instead disrupt the ring on a short timescale. The ring found around Haumea is stable despite the rise in the impact velocities that is due to the asymmetric shape of the the body and the presence of a 3:1 resonance with the rotation of the central body. A ring close to an oblate central body should be searched for in the proximity of the equatorial plane, where the J2 perturbations protect it against the perturbations of an external inclined satellites. In an inclined configuration, the J2 term is itself disruptive.

description: Anhand einer Modellanalyse zur Standortbewertung der Biogasproduktion wird die ökono-misch-ökologische Vorzüglichkeit der Energiepflanzen Silomais, Zuckerrüben, Getreide-ganzpflanzensilage und Winterweizenkorn ermittelt. Ein besonderer Fokus liegt dabei auf der Zuckerrübe als Substitut zu Silomais, dessen Anbau sich zunehmender ökologischer und ge-sellschaftlicher Kritik ausgesetzt sieht. Im Modell werden rund 8.000 georeferenzierte Bio-gasanlagen betrachtet. Die Substratbereitstellungskosten werden anlagenspezifisch unter regi-onalen Produktionsbedingungen für die genannten Kulturen berechnet. Aufbauend auf diesem Ergebnis wird der Substratmix in einem linearen Kosten-Minimierungsansatz für jede Anlage berechnet. Abschließend werden auf dem Modellergebnis aufbauend, anlagenspezifische Treibhausgasbilanzen berechnet und auf räumlicher Ebene (Landkreise) aggregiert. Die Er-gebnisse zeigen, dass Silomais mit rund 41,8 Millionen Tonnen Einsatzmenge mit Abstand das vorzüglichste Substrat darstellt. Zuckerrüben werden mit rund 0,841 Millionen Tonnen eingesetzt. Die Berechnung der Treibhausgasbilanzen ergibt im Mittel über die betrachteten Anlagen 0,135 kgCO2eq pro produzierter kWh Strom mit Variationen in Abhängigkeit des Standorts.

description: In this paper, we consider the task of predicting travel times between two arbitrary points in an urban scenario. We view this problem from two temporal perspectives: long-term forecasting with a horizon of several days and short-term forecasting with a horizon of one hour. Both of these perspectives are relevant for planning tasks in the context of urban mobility and transportation services. We utilize tree-based ensemble methods that we train and evaluate on a dataset of taxi trip records from New York City. Through extensive data analysis, we identify relevant temporal and spatial features. We also engineer additional features based on weather and routing data. The latter is obtained via a routing solver operating on the road network. The computational results show that the addition of this routing data can be beneficial to the model performance. Moreover, employing different models for short and long-term prediction is useful as short-term models are better suited to mirror current traffic conditions. In fact, we show that accurate short-term predictions may be obtained with only little training data.
Studies of non-covalent myoglobin interactions by electrospray ionization mass spectrometry
Creators: name: Mark, Kevin J.
Publisher: name: University of British Columbia
Year: 2011

description: Acid and base-induced unfolding of myoglobin in solution is monitored by electrospray ionization mass spectrometry. It is shown that acid-induced Mb unfolding causes the appearance of different charge state distributions in positive and negative ion modes compared to base-induced unfolding, suggesting different protein conformations in solution. Collision cross sections of both apomyoglobin and holomyoglobin ions are measured at various orifice-skimmer voltage differences (AVOS). The results show that at low AVOS, apomyglobin ions have greater collision cross sections than holomyoglobin ions, indicating that heme, when attached to the globin, helps maintain a more compact myoglobin structure. Coulomb effects in binding of heme in gas phase holomyoglobin ions are studied. Positive and negative ions are formed from solutions of Fe⁺² (ferromyoglobin) and Fe⁺³ (ferrimyoglobin). The energy that must be added to the resulting holomyoglobin ions to cause heme loss is measured with a triple quadrupole MS/MS system. With negative ions, neutral heme is lost, regardless of the charge state of Fe in solution. It is likely that the Fe⁺³ is reduced to Fe⁺² in the negative electrospray process. With positive ions, predominantly neutral heme loss is observed for ions formed from ferromyoglobin in solution, and positive heme loss for ions formed from ferrimyoglobin in solution. The energies required to induce neutral heme loss are similar for positive and negative ions. The energies required to induce charged heme loss from positive holomyoglobin ions are significantly less. Coulomb repulsion between the charged heme and charged protein appears to lower the barrier for heme loss. These results are consistent with a simple model of a long range Coulomb repulsion and a short range attraction between the heme and protein.

description: Vorliegende Studie analysiert die technische Umwelteffizienz und die Produktivitätsentwicklung von Marktfruchtbetriebe unter Berücksichtigung von Treibhausgasemissionen als unerwünschten Output. Basierend auf einer erweiterten hyperbolischen stochastischen Distanzfunktion werden Schattenpreise von Treibhausgasemissionen eruiert sowie der Einfluss exogener Faktoren auf die Umwelteffizienz getestet und die Treiber der Produktivitätsentwicklung quantifiziert. Datengrundlage bildet ein balanciertes Panel von 141 norddeutschen Marktfruchtbetrieben im Zeitraum der Wirtschaftsjahre 2002/03 bis 2009/10. Als Ergebnis ist festzuhalten, dass einerseits mit 95,6% ein relativ hohes Niveau an Umwelteffizienz festzustellen ist, aber andererseits noch 8,6% der produktspezifischen Emissionen eingespart werden können. Innerhalb des Samples beeinflussen Standorte mit einer höheren Anzahl an Bodenpunkten sowie ein höherer Fruchtfolgeanteil an Getreide und Zuckerrüben die Umwelteffizienz positiv. Hingegen wirken ein zunehmender Anteil an organischen Düngern und eine höhere Rate an ausgelagerten Dienstleistungen Umwelteffizienz mindernd. Die Schattenpreise der Treibhausgasemissionen bewegen sich im Mittel zwischen 1,71 und 3,41 € je Tonne CO2-Äquivalent. Für die Schattenpreise ist generell eine steigende Tendenz im Beobachtungszeitraum festzustellen. Die ermittelte Produktivitätssteigerung wird maßgeblich von technischem Fortschritt vorangetrieben. Änderungen der Umwelteffizienz üben im Durchschnitt der Jahre lediglich marginalen positiven Einfluss auf die Produktivitätsentwicklung aus. Veränderungen der Skalengröße hingegen hemmen die Produktivitätsentwicklung geringfügig.

description: The electronic and local structural properties of CuO under pressure have been investigated by means of X-ray absorption spectroscopy (XAS) at Cu K edge and ab-initio calculations, up to 17 GPa. The crystal structure of CuO consists of Cu motifs within CuO$_4$ square planar units and two elongated apical Cu-O bonds. The CuO$_4$ square planar units are stable in the studied pressure range, with Cu-O distances that are approximately constant up to 5 GPa, and then decrease slightly up to 17 GPa. In contrast, the elongated Cu-O apical distances decrease continuously with pressure in the studied range. An anomalous increase of the mean square relative displacement (EXAFS Debye Waller, σ$^2$) of the elongated Cu-O path is observed from 5 GPa up to 13 GPa, when a drastic reduction takes place in σ$^2$. This is interpreted in terms of local dynamic disorder along the apical Cu-O path. At higher pressures (P>13 GPa), the local structure of Cu$^{2+}$ changes from a 4-fold square planar to a 4+2 Jahn-Teller distorted octahedral ion. We interpret these results in terms of the tendency of the Cu$^{2+}$ ion to form favorable interactions with the apical O atoms. Also, the decrease in Cu-O apical distance caused by compression softens the normal mode associated with the out-of-plane Cu movement. CuO is predicted to have an anomalous rise in permittivity with pressure as well as modest piezoelectricity in the 5-13 GPa pressure range. In addition, the near edge features in our XAS experiment show a discontinuity and a change of tendency at 5 GPa. For P < 5 GPa the evolution of the edge shoulder is ascribed to purely electronic effects which also affect the charge transfer integral. This is linked to a charge migration from the Cu to O, but also to an increase of the energy band gap, which show a change of tendency occurring also at 5 GPa.

description: In dieser Studie werden die Einflussfaktoren auf die Abweichungen der Investitionsentscheidungen deutscher Schweinehalter vom optimalen Investitionsverhalten nach Realoptionsansatz (ROA) analysiert. Hierzu wird ein Experiment durchgeführt, in dem ökologische und konventionelle Schweinehalter die Möglichkeit haben, in einen konventionellen oder in einen ökologischen Maststall zu investieren. Normative Benchmarks gemäß ROA werden ermittelt und mit den beobachteten Investitionsentscheidungen der Schweinehalter verglichen. Zur Analyse der Faktoren, die die Abweichungen beeinflussen, wird ein multinomiales gemischtes Logit-Modell geschätzt. Unsere Ergebnisse zeigen signifikante Einflüsse nicht-monetärer Variablen: Zum einen wird ein signifikanter Framingeffekt beobachtet. Das bedeutet, dass sich die Abweichungen vom ROA verändern, wenn die Schweinehalter in die praktizierte oder in die nicht-praktizierte Bewirtschaftungsweise investieren. Zum anderen wird ein Lerneffekt ausgemacht: Die steigende Erfahrung im Experiment führt zu späteren Investitionsentscheidungen. Außerdem wird der Einfluss betriebsspezifischer und soziodemografischer Variablen auf die Abweichungen festgestellt.

description: Todos os anos milhares de latas de alumínio são descartadas antes mesmo de chegarem ao consumidor final, um dos locais onde isto pode ocorrer é na própria indústria que utiliza tais embalagens para acondicionar seus produtos. Tal perda traz prejuízos financeiros para a empresa e prejuízos ambientais para a natureza, pois a extração de minério para a produção de alumínio se intensifica. Diante disso, o presente trabalho tem por objetivo examinar a aplicação do Método de Análise e Solução de Problemas (MASP) para que haja mitigação das perdas de latas vazias em um armazém de uma indústria de bebidas. O MASP é um método que pretende apresentar o que é mais correto, racional, estruturado e sistemático para o desenvolvimento de um processo de melhoria dentro da esfera organizacional. Após a conclusão do trabalho pode-se perceber com clareza que o MASP serve perfeitamente como solucionador reativo de problemas, ajudando especificamente nesse caso, a alcançar resultados importantíssimos, tais como: a redução das perdas de latas de alumínio de 80.000 para 27.500 e um ganho financeiro aproximado em torno de R$ 11.500,00 mensais.

description: Meteors have long been studied to determine their origins, whether it be the initial curiosity of ‘What is this bright light streaking across the sky?’, or where these chunks of celestial rocks come from in our Solar system. Colour analysis of meteors has been previously attempted with limited results. Differentiating meteors by colour alone enables efficient automated surveys that help provide a link between meteoroids and meteorites. Currently, there is promising, but limited knowledge regarding the spectra of meteors, with several small studies performed. These studies are hampered by the difficulties of gaining meteor spectra due to their serendipitous nature, and the narrow field of view of current spectrographic instruments. Using photometry, which measures the brightness in a particular colour, to study these events leads to greater accessibility, but a lower accuracy. This can be offset by the larger number of observations possible with a photometric setup.With access to the Desert Fireball Network’s archival data, I have undertaken a pilot study to assess the viability of a large-scale study of meteor colour to detect noticeable colour variations or consistent trends within RGB observations.Through an initial study of the data, I found that colour-indices at a fixed altitude of 75 km reveals a relationship between the colour-index and the initial velocity of an incoming fireball, which is congruent with previous literature. This could allow colour to be used as a proxy for velocity if velocity data is unavailable, or potentially allow shower associations to be proposed or confirmed from a single camera observation. Given the small nature of this data set and the compact time frame in which the datawas observed, along with the annual nature of meteor showers, further investigation with the completeDFNdataset is required to confirm if these results are consistent throughout the complete data set.
