description: Molecular hydrogen being unobservable in cold molecular clouds, the column density measurements of molecular gas currently rely either on dust emission observation in the far-IR or on star counting. (Sub-)millimeter observations of numerous trace molecules are effective from ground based telescopes, but the relationships between the emission of one molecular line and the H2 column density (NH2) is non-linear and sensitive to excitation conditions, optical depths, abundance variations due to the underlying physico-chemistry. We aim to use multi-molecule line emission to infer NH2 from radio observations. We propose a data-driven approach to determine NH2 from radio molecular line observations. We use supervised machine learning methods (Random Forests) on wide-field hyperspectral IRAM-30m observations of the Orion B molecular cloud to train a predictor of NH2, using a limited set of molecular lines as input, and the Herschel-based dust-derived NH2 as ground truth output. For conditions similar to the Orion B molecular cloud, we obtain predictions of NH2 within a typical factor of 1.2 from the Herschel-based estimates. An analysis of the contributions of the different lines to the predictions show that the most important lines are $^{13}$CO(1-0), $^{12}$CO(1-0), C$^{18}$O(1-0), and HCO$^+$(1-0). A detailed analysis distinguishing between diffuse, translucent, filamentary, and dense core conditions show that the importance of these four lines depends on the regime, and that it is recommended to add the N$_2$H$^+$(1-0) and CH$_3$OH(20-10) lines for the prediction of NH2 in dense core conditions. This article opens a promising avenue to directly infer important physical parameters from the molecular line emission in the millimeter domain. The next step will be to try to infer several parameters simultaneously (e.g., NH2 and far-UV illumination field) to further test the method. [Abridged]

Synthesis of chiral bis(amidate)bis(amido) titanium and zirconium complexes for catalyzed asymmetric alkene hydroamination
Creators: name: Wood, Mark Christopher
Publisher: name: University of British Columbia
Year: 2011

description: Recent advances in transition metal and lanthanide catalyzed hydroamination have changed the way people think about the formation of C-N bonds. As a major contribution to this area of research, we have synthesized the first neutral group 4 precatalysts capable of enantioselective alkene hydroamination. We took advantage of a modular amidate ligand set to alter both the electronic and steric properties of the precatalysts. The amidate ligands employed in these catalysts were synthesized by reacting an axially chiral 2,2'diamino-6,6'-dimethylbiphenyl diamine with a corresponding acyl chloride or anhydride. Further reaction of the chiral amide proligand with Ti(NMe₂)₄ or Zr(NMe₂)₄, produced the bis(amidate)bis(amido) titanium and zirconium precatalysts in quantitative yields. [formula omitted] Enantioselectivity and reactivity investigations for aminoalkene hydroamination were conducted on the group 4 complexes prepared, and complex A produced the most excellent enantioselectivities. From this investigation, minor alterations to the electronic and steric properties of the ligand showed significant effects on reactivity and enantioselectivity. Further substrate scope investigations, using precatalyst A, displayed high yields, moderate reaction times and enantioselectivities up to 93% ee. Most importantly, the structural and substrate scope investigation provided a mechanistic rationale for observed trends in reactivity and enantioselectivity, yielding valuable insight for future catalyst development.

description: The construction of plants for generation of biogas depends on planning and design for each case. A good project is essential to ensure a good operation of the plant. The methodological framework proposed in this paper should facilitate the choice of digestion, design of bioreactors, stages, loading, handling, storage and the use of biogas. This paper aims to investigate and apply knowledge of research in creating a model for the design of biogas plants. The application of the proposed model proposes a design of a biogas plant for the treatment of biomass composed of corn silage. The use of the generated model provides results of the case study.

description: Both the group velocity and phase velocity of two solitons can be synchronized by a Kerr-effect mediated interaction, causing what is known as soliton trapping. Trapping can occur when solitons travel through single-pass optical fibers or when circulating in optical resonators. Here, we demonstrate and theoretically explain a new manifestation of soliton trapping that occurs between counter-propagating solitons in microresonators. When counter-pumping a microresonator using slightly detuned pump frequencies and in the presence of backscattering, the group velocities of clockwise and counter-clockwise solitons undergo periodic modulation instead of being locked to a constant velocity. Upon emission from the microcavity, the solitons feature a relative oscillatory motion having an amplitude that can be larger than the soliton pulse width. This relative motion introduces a sideband fine structure into the optical spectrum of the counter-propagating solitons. Our results highlight the significance of coherent pumping in determining soliton dynamics within microresonators and add a new dimension to the physics of soliton trapping.

description: Title: Fundamentals and Experimental Validation of the Unified Theory of Informational Spin (TGU)

Description:This paper introduces the Unified Theory of Informational Spin (TGU), a groundbreaking framework that redefines the role of information in the gravitational and quantum realms. By proposing that informational spin governs the structural coherence of physical systems, TGU offers a compelling alternative to the conventional reliance on dark matter and dark energy. The paper presents two validation experiments: the modeling of informational distribution in galactic superclusters and the analysis of orbital coherence in planetary systems. The results demonstrate that TGU accurately predicts gravitational phenomena, reinforcing the idea that information is central to the universe's structure. This work bridges gaps between classical and quantum physics while presenting a viable model for understanding the cosmos through informational coherence.

description: Durch den demografischen Wandel und einen vergleichsweise robusten Arbeitsmarkt in Deutschland ist das Thema Fachkräftemangel inzwischen auch in der deutschen Landwirtschaft ein wichtiges Thema. Der vorliegende Bericht untersucht eine Maßnahme, die diesen Mangel teilweise bewältigen helfen kann: das Engagement von qualifizierten osteuropäischen Migranten. Wir versuchen zu verstehen, inwieweit die sich abzeichnende Lücke mit qualifizierten osteuropäischen Fachkräften geschlossen werden kann und wie hoch das potenzielle Fachkräfteangebot ist. Am Beispiel von Bulgarien und Russland identifizieren wir die Absolventen von Agraruniversitäten als potenzielle Zielgruppe und erstellen ein Profil von Personen mit erhöhter Auswanderungsbereitschaft. Generell zeigen die Ergebnisse, dass es ein begrenztes, jedoch nicht völlig unbedeutendes Potenzial gibt, qualifizierte osteuropäische Fachkräfte für den deutschen Agrarsektor zu gewinnen. Einkommensunterschiede im Agrarbereich, die Unterversorgung mit öffentlichen Gütern und verbreitete Korruption in den Herkunftsländer scheinen die wichtigsten Anreize für eine Auswanderung zu sein. Junge Agrarabsolventen, die weltoffen sind, bereits über Auslandserfahrungen verfügen und wenig in lokale soziale Netzwerke in den Herkunftsländer eingebunden sind, kommen als Fachkräfte in Frage. Die Migration von qualifizierten osteuropäischen Arbeitskräften lässt sich mit Praktikumsprogrammen als Auswahl- und Ausbildungsmechanismus fördern.
Synthesis and application of highly dispersed ordered mesoporous silicon-doped Pd-alumina catalyst with high thermal stability

description: Employing P123 as a structure directing agent and acetic acid as an interfacial protector, ordered mesoporous silicon-doped γ-alumina with high thermal stability was synthesized through a modified sol–gel process by adding aluminum isopropoxide in batches to control the hydrolytic and condensation rate of Al3+. When the silicon content was 10–25 wt%, the specific surface area of the as-obtained samples were higher than others. Especially when the silicon content up to 20 wt%, the sample still maintained ordered mesoporous c-Al2O3 phase with a large specific surface area of 139.8 m2 g-1 and narrow pore size distribution even the calcination temperature up to 1100 ℃. Taking as-synthesized ordered mesoporous alumina (OMA) as carrier, the catalysts with high thermal stability supported by Pd were obtained by a facile process of thermal incipient wetness impregnation, which shows highly dispersed nano-particles and ordered mesostructure. When applied the catalysts in the catalytic converters of simulated exhaust automobile gases, it was found that the ordered mesostructure and high surface area showed significant
effects in promoting catalytic activity. The as-synthesized ordered mesoporous Pd-alumina catalyst exhibited an excellent catalytic activity for gas mixture including CO, NO and hydrocarbon (HC).

description: A two-dimensional array of Kerr-nonlinear parametric oscillators (KPOs) with local four-body interactions is a promising candidate for realizing an Ising machine with all-to-all spin couplings, based on adiabatic quantum computation in the Lechner-Hauke-Zoller (LHZ) scheme. However its performance has been evaluated for only a few KPOs. By numerically simulating more KPOs, here we show that the performance can be dramatically improved by reducing inhomogeneity in photon numbers induced by the four-body interactions. The discrepancies of the photon numbers can be corrected by tuning the detunings of KPOs depending on their positions, without monitoring their states during adiabatic time evolution. This correction can be used independent of the number of KPOs in the LHZ scheme and thus can be applied to large-scale implementation.

description: We have used hydrodynamical simulations to model the formation of the closest giant elliptical galaxy, Centaurus A. We find that a single major merger event with a mass ratio up to 1.5, and which has happened ~2 Gyr ago, is able to reproduce many of its properties, including galaxy kinematics, the inner gas disk, stellar halo ages and metallicities, and numerous faint features observed in the halo. The elongated halo shape is mostly made of progenitor residuals deposited by the merger, which also contribute to stellar shells observed in the Centaurus A halo. The current model also reproduces the measured Planetary Nebulae line of sight velocity and their velocity dispersion. Models with small mass ratio and relatively low gas fraction result in a de Vaucouleurs profile distribution, which is consistent with observations and model expectations. A recent merger left imprints in the age distribution that are consistent with the young stellar and Globular Cluster populations (2-4 Gyrs) found within the halo. We conclude that even if not all properties of Centaurus A have been accurately reproduced, a recent major merger has likely occurred to form the Centaurus A galaxy as we observe it at present day.

description: Collaboration and participation are transforming architectural disciplines. Especially in public and collective projects, where more democratic decision-making processes are starting to be implemented. Within this changing context, socially engaged universities can contribute to generate new knowledge around participatory processes and design methods. This can be achieved through design-based university-community partnerships, where useful learning for communities, students and academics can be generated. Following a Participatory Action Research methodology, different partnerships informed this paper. These were structured around landscape architecture university courses with the aim to experience service learning. The article explains the adaptability of the applied methodology and its capacity to serve community needs by seeking design implementation. It shows how partnerships allowed students to learn about new professional roles and design processes through direct experience, while academics developed practice-based research. Finally, it showcases how socially engaged academics can generate knowledge through practice and from the outcomes of that practice.

Especialmente en proyectos públicos y colectivos, donde se están empezando a desarrollar sistemas de decisión más democráticos. En un contexto donde cambian las metodologías de trabajo y los roles tradicionales, las universidades interesadas en desarrollar aprendizaje-servicio pueden contribuir a generar conocimiento si se asocian a grupos comunitarios. Utilizando cursos de paisajismo, y siguiendo una metodología de acción participativa, diferentes colaboraciones informan este artículo. En él se explica la adaptabilidad de la metodología aplicada y cómo se intenta dar respuesta a los objetivos de los grupos comunitarios al perseguir la construcción de los proyectos. Esta voluntad práctica y participativa permite a los alumnos aprender nuevos roles y métodos de diseño a través de la experiencia directa. A su vez, los académicos pueden desarrollar nuevos procesos pedagógicos y crear proyectos de investigación tanto entre proyectos como de cada proyecto.

description: Der Discounter ist der Deutschen liebste Lebensmitteleinkaufsstätte – trotz zahlreicher Alter-nativen. Warum also sind Discounter so beliebt? In einem theoretischen Überblick werden zunächst Entscheidungskriterien herausgearbeitet, die die Wahl einer Einkaufsstätte beein-flussen, mit besonderem Augenmerk auf Transaktionskosten. Da Lebensmittel als „fast moving consumer goods“ (FMCG) vom Verbraucher regelmäßig und wiederkehrend nachge-fragt werden, spielt neben den Transaktionskosten das Image der Einkaufsstätte vermutlich eine große Rolle. Die vorliegende Studie zeigt, dass deutsche Verbraucher dem Discounter im Vergleich zu anderen Betriebstypen ein negatives Image zuschreiben. Aus transaktionskostentheoretischen Gesichtspunkten ist die Wahl des Discounters als Haupteinkaufsstätte dennoch vorteilhaft. Die empirische Analyse belegt einerseits, dass anscheinend „out-of-pocket“-Kosten, gemessen als Entfernung zum Wohnort, im Super- oder Verbrauchermarkt und Discounter geringer sind als in den anderen Betriebstypen. Kunden des Discounters schätzen andererseits, neben den günstigen Preisen, vor allem die Möglichkeit, einen schnellen Einkauf zu tätigen, d.h. die wahrgenommenen Transaktionskosten werden vom Verbraucher niedriger eingeschätzt als in den anderen Betriebstypen.

description: We study constraints on a number of patch inflationary models in noncommutative spacetime using a compilation of recent high-precision observational data. In particular, the four-dimensional General Relativistic (GR) case, the Randall-Sundrum (RS) and Gauss-Bonnet (GB) braneworld scenarios are investigated by extending previous commutative analyses to the infrared limit of a maximally symmetric realization of the stringy uncertainty principle. The effect of spacetime noncommutativity modifies the standard consistency relation between the tensor spectral index and the tensor-to-scalar ratio. We perform likelihood analyses in terms of inflationary observables using new consistency relations and confront them with large-field inflationary models with potential V \propto \vp^p in two classes of noncommutative scenarios. We find a number of interesting results: (i) the quartic potential (p=4) is rescued from marginal rejection in the class 2 GR case, and (ii) steep inflation driven by an exponential potential (p \to \infty) is allowed in the class 1 RS case. Spacetime noncommutativity can lead to blue-tilted scalar and tensor spectra even for monomial potentials, thus opening up a possibility to explain the loss of power observed in the cosmic microwave background anisotropies. We also explore patch inflation with a Dirac-Born-Infeld tachyon field and explicitly show that the associated likelihood analysis is equivalent to the one in the ordinary scalar field case by using horizon-flow parameters. It turns out that tachyon inflation is compatible with observations in all patch cosmologies even for large p.

description: This paper presents preliminary results of the design, development, and evaluation of a hand rehabilitation glove fabricated using lobster-inspired hybrid design with rigid and soft components for actuation. Inspired by the bending abdomen of lobsters, hybrid actuators are built with serially jointed rigid shells actuated by pressurized soft chambers inside to generate bending motions. Such bio-inspiration absorbs features from the classical rigid-bodied robotics with precisely-defined motion generation, as well as the emerging soft robotics with light-weight, physically safe, and adaptive actuation. The fabrication procedure is described, followed by experiments to mechanically characterize these actuators. Finally, an open-palm glove design integrated with these hybrid actuators is presented for a qualitative case study. A hand rehabilitation system is developed by learning patterns of the sEMG signals from the user's forearm to train the assistive glove for hand rehabilitation exercises.

description: Dentre as energias alternativas o biogás é aquele que possui a maior gama de oportunidades para sua comercialização. Pode ser vendido na forma de calor (energia térmica), energia elétrica e biogás bruto. O setor de produção e comercialização do biogás brasileiro é carente e inexpressivo. Há uma carência na cadeia de suprimentos, recursos humanos capacitados, leis e normas reguladoras, abrangentes, capazes de incentivar e proteger investidores e consumidores. No mercado brasileiro atual, as opções que existem para a negociação do biogás são: energia elétrica e biometano. Nestes dois casos a margem de lucro é pequena em comparação com o que se pode auferir no mercado residencial de gás de cozinha. Em face desta realidade é possível concluir que, dentre as várias alternativas de comercialização do biogás, o desafio maior está em desenvolver e/ou adaptar materiais para o envase do biogás em cilindros e assim poder competir no mercado de gás de cozinha.

Synthesis of UDP-6-deoxy-6,6-difluoro-D-GlcNAc : a potential mechanism-based inhibitor of pseB
Creators: name: Bassiri, Jackie Mehrnaz
Publisher: name: University of British Columbia
Year: 2011

description: Pseudaminic acid is a nine carbon sugar, similar to sialic acid, and has been found to play an important role in the biosynthesis of flagella in pathogenic bacteria such as C. jejuni and H. pylori. For these bacteria the flagella is crucial in motility and colonization of the host. Because this sugar is found only in bacteria, enzymes required for its biosynthesis serve as novel targets for antibiotic development. A UDP-GlcNAc dehydratase, pseB, catalyses the first step of pseudaminic acid biosynthesis in C. jejuni. This enzyme catalyzes the conversion of UDP-GlcNAc to UDP-6-deoxy-4-keto- HexNAc. The proposed mechanism of this conversion is composed of oxidation of the C4 hydroxyl resulting in the formation of a 4-keto group, then a dehydration across the bond between C5 and C6 producing a UDP-4-keto-5,6-ene-hexose, and finally reduction in which a hydride from the enzyme bound NADFt cofactor is transferred to C6, and C5 is reprotonated on the opposite face such that the stereocentre at C5 is inverted during this dehydration reaction. In 1998, the synthesis of CDP-6-deoxy-6,6-difluoro-D-glucose, 9, was published by Chang et al. This compound was the first mechanism-based inactivator known for a dehydratase enzyme, more specifically, CDP-D-glucose 4,6-dehydratase, isolated from Yersinia pseudotuberculosis. Based on this work, a 10-step synthesis of UDP-6-deoxy- 6,6-difluoro-D-GlcNAc 11 was completed which generated a potential mechanism-based inhibitor for pseB. [image in original] The preliminary enzyme kinetics performed did not support 11 as a mechanismbased inactivator of pseB. One possible explanation for this is based on the steric aspect of the inhibitor vs. the substrate. The two fluorine groups on the C-6 positions are possibly too bulky for the inhibitor to bind the enzyme active site and cause inactivation. Another reason might be that the H-bonding of the C-6 hydroxyl group of the substrate to the enzyme is crucial in substrate binding. When it is replaced with two fluorines the lack of this H-bonding does not allow binding of the inhibitor to the active site.

description: Dynamic optimization problems have gained significant attention in evolutionary computation as evolutionary algorithms (EAs) can easily adapt to changing environments. We show that EAs can solve the graph coloring problem for bipartite graphs more efficiently by using dynamic optimization. In our approach the graph instance is given incrementally such that the EA can reoptimize its coloring when a new edge introduces a conflict. We show that, when edges are inserted in a way that preserves graph connectivity, Randomized Local Search (RLS) efficiently finds a proper 2-coloring for all bipartite graphs. This includes graphs for which RLS and other EAs need exponential expected time in a static optimization scenario. We investigate different ways of building up the graph by popular graph traversals such as breadth-first-search and depth-first-search and analyse the resulting runtime behavior. We further show that offspring populations (e. g. a (1+$λ$) RLS) lead to an exponential speedup in $λ$. Finally, an island model using 3 islands succeeds in an optimal time of $Θ(m)$ on every $m$-edge bipartite graph, outperforming offspring populations. This is the first example where an island model guarantees a speedup that is not bounded in the number of islands.

description: In this thesis, the electronic structure and reactivities of the perfect, defected, and doped single-walled carbon nanotubes (SWCNTs) have been studied by various theoretical methods, including density functional theory, semiempirical methods, and force fields. Among different defects of the SWCNTs, we have concentrated our studies on the vacancy defect and substitutional^ doped defect. Of the vacancy defected SWCNTS, we first studied their geometries, energetics, and electronic structures. After comparing the vacancy defected SWCNTs with the perfect SWCNTs, we found that the vacancy defect introduces localized electronic states near the Fermi level, thus enhancing the chemical reactivity of the SWCNTs. We then studied the reaction mechanisms of the vacancy defect on the (5,5) SWNCT with NO and O₃. We have discovered that the reaction between NO and the vacancy defect provides a possible way to fabricate the substitutionally N-doped SWCNTs. We also obtained a microscopic understanding of the ozonization at the vacancy defect site of the SWCNT. To further understand the doping effects, we have studied the precious metal Ptdoped SWCNTs at different positions of the (5,5) SWCNT rod. We found that the doping of Pt in the SWCNT rod results in localized states at Pt, thus rendering Pt as the active center in chemical reactions. We found that the doping of Pt in the middle of the sidewall of the nanorod has a stronger interaction with adsorbates (e.g., H₂ and C₂H₄) than the doping of Pt at the hemispheric caps of the nanorod.

description: We report here a facile approach for the construction of 3D Fe-doped γ-Al2O3. In this method, by the addition of urea and citric acid during synthesis, hollow spheres with a multi-modal porous structure can be successfully produced. The obtained Fe-doped γ-Al2O3 microspheres are about 0.8–1.5 μm in diameter with a shell thickness of 200 nm. Compared with γ-Al2O3, the Fe-doped γ-Al2O3 catalysts exhibit enhanced activity in the selective oxidation of H2S. According to the results of systematic studies, it is inferred that both Lewis acid sites and chemically adsorbed oxygen at oxygen vacancies have a great influence on catalytic activity. In addition, the nature of active sites and the reaction mechanism for H2S selective oxidation over these catalysts are disclosed.
Change Point Detection in Software Performance Testing

description: We describe our process for automatic detection of performance changes for a software product in the presence of noise. A large collection of tests run periodically as changes to our software product are committed to our source repository, and we would like to identify the commits responsible for performance regressions. Previously, we relied on manual inspection of time series graphs to identify significant changes. That was later replaced with a threshold-based detection system, but neither system was sufficient for finding changes in performance in a timely manner. This work describes our recent implementation of a change point detection system built upon the E-Divisive means algorithm. The algorithm produces a list of change points representing significant changes from a given history of performance results. A human reviews the list of change points for actionable changes, which are then triaged for further inspection. Using change point detection has had a dramatic impact on our ability to detect performance changes. Quantitatively, it has dramatically dropped our false positive rate for performance changes, while qualitatively it has made the entire performance evaluation process easier, more productive (ex. catching smaller regressions), and more timely.
Benchmarking neural embeddings for link prediction in knowledge graphs under semantic and structural changes

description: Recently, link prediction algorithms based on neural embeddings have gained tremendous popularity in the Semantic Web community, and are extensively used for knowledge graph completion. While algorithmic advances have strongly focused on efficient ways of learning embeddings, fewer attention has been drawn to the different ways their performance and robustness can be evaluated. In this work we propose an open-source evaluation pipeline, which benchmarks the accuracy of neural embeddings in situations where knowledge graphs may experience semantic and structural changes. We define relation-centric connectivity measures that allow us to connect the link prediction capacity to the structure of the knowledge graph. Such an evaluation pipeline is especially important to simulate the accuracy of embeddings for knowledge graphs that are expected to be frequently updated.

description: In this paper, we develop a model that explains the exporters’ behaviour in international commodity markets considering explicitly the case of an imperfectly competitive structure of these markets. More specifically, drawing from the imperfect competition and trade literature, we derive price transmission equations between producer and consumer prices and between producer and export prices that can be included in large commodity models in order to verify how results of these models change assuming the imperfect competition hypothesis. The results obtained carrying out a simple simulation exercise, with two competing exporting countries and one importing region, show the relevance of assuming imperfect competition in commodity markets.

description: This article will approach the low-carbon technology of Micro-CHP (combined heat and power). It is the process of generating both electrical power and useful heat in small scale (electrical power <35 kW) from a single source of fuel such biofuels. Thus, these technologies and its equipment will be treated linking each one to domestic and residential application. It will also be shown the perspective of the third generation: cooling, heat and power generation and decentralized energy for domestic use like hot water purposes. These domestic combined heat and power (DCHP) is already being developed in some European countries. Therefore, it may be brought to Brazilian cities, exploiting the large quantity of biomass resources available in the country.

We find that when moving in the context of a familiar market for consumers (i.e., the food market) we only observe weak effects of inconsistencies. In addition, we find that the IV method is no better (and no worse) than the CV method in generating more consistent preference orderings. Surprisingly, we also find that the IV method generates higher valuations than CV, rendering one of its advantages of mitigating social desirability bias questionable.

description: This article presents a method and program for identifying poorly fitting observations for maximum-likelihood regression models for categorical dependent variables. After estimating a model, the program least likely will list the observations that have the lowest predicted probabilities of observing the value of the outcome category that was actually observed. For example, when run after estimating a binary logistic regression model, least likely will list the observations with a positive outcome that had the lowest predicted probabilities of a positive outcome and the observations with a negative outcome that had the lowest predicted probabilities of a negative outcome. These can be considered the observations in which the outcome is most surprising given the values of the independent variables and the parameter estimates and, like observations with large residuals in ordinary least squares regression, may warrant individual inspection. Use of the program is illustrated with examples using binary and ordered logistic regression.
