Robust bone detection in ultrasound using combined strain imaging and envelope signal power detection
Creators: name: Hussain, Mohammad Arafat
Publisher: name: University of British Columbia
Year: 2015

description: Using ultrasound for tool navigation in an orthopaedic surgery requires bone localization in ultrasound, a procedure which remains challenging despite encouraging advances in its practice. Current methods, e.g., the local image phase-based feature analysis, have shown promising results but continue to rely on delicate parameter selection processes and to be prone to error at confounding soft tissue interfaces of similar appearance to bone interfaces. In addition, the 3-dimensional phase-features-based automatic bone segmentation method is found to be time inefficient (at ~2 minutes). We have proposed a different approach to bone segmentation by combining ultrasound strain imaging and envelope power detection methods. After an estimation of the strain and envelope power maps, we subsequently fused these maps into a single combined map that corresponds robustly to the actual bone boundaries. This study has achieved a marked reduction in false positive bone responses at the soft tissue interfaces. We also incorporated the depth-dependent cumulative power of the envelope into the elastographic data as well as incorporated an echo de-correlation measurement-based weight to fuse the strain and envelope map. We also employed a data driven scheme to detect the presence of any bone discontinuity in the scanned ultrasound image and introduced a multivariate non-parametric Gaussian mixture regression to be used over the maximum intensity points of the fused map. Finally, we developed a simple yet effective means to perform 3-dimensional bone surface extractions using a surface growing approach that is seeded from the 2-dimensional bone contours. We employed mean absolute error calculations between the actual and estimated bone boundaries to show the extent of the false positives created; our methods showed an average improvement in the mean absolute error of 20% on both the 2- and 3-dimensional finite-element-models, and of 18% and 23%, respectively, on the 2- and 3-dimensional experimental phantom data, when compared with that of the local phase-based methods. Validation on the 2- and 3-dimensional clinical in vivo data also demonstrates, respectively, an average improvement in the mean absolute fitting error of 55% and an 18 times improvement in the computation time.

description: Optimal quantum cloning is the process of making one or more copies of an arbitrary unknown input quantum state with the highest possible fidelity. All reported demonstrations of quantum cloning have so far been limited to copying two-dimensional quantum states, or qubits. We report the experimental realization of the optimal quantum cloning of four-dimensional quantum states, or ququarts, encoded in the polarization and orbital angular momentum degrees of freedom of photons. Our procedure, based on the symmetrization method, is also shown to be generally applicable to quantum states of arbitrarily high dimension -- or qudits -- and to be scalable to an arbitrary number of copies, in all cases remaining optimal. Furthermore, we report the bosonic coalescence of two single-particle entangled states.

description: Abstract:
This map is not intended to be used for selecting individual sites. Its purpose is to inform land-use planners, government officials, and the public in a general way about geologic bedrock conditions that affect the selection of sites for various purposes. The properties of thick soils may supercede those of the underlying bedrock and should be considered on a site-to-site basis. At any site, it is important to understand the characteristics of both the soils and the underlying rock.

description: The interaction of a quantum field with a background containing a Dirac delta function with support on a surface of codimension 1 represents a particular kind of matching conditions on that surface for the field. In this article we show that the worldline formalism can be applied to this model. We obtain the asymptotic expansion of the heat-kernel corresponding to a scalar field on $\mathbb{R}^{d+1}$ in the presence of an arbitrary regular potential and subject to this kind of matching conditions on a flat surface. We also consider two such surfaces and compute their Casimir attraction due to the vacuum fluctuations of a massive scalar field weakly coupled to the corresponding Dirac deltas.

description: A cerium containing pnictide, CeNiAsO, crystallized in the ZrCuSiAs type structure, has been investigated by measuring transport and magnetic properties, as well as specific heat. We found that CeNiAsO is an antiferromagnetic dense Kondo lattice metallic compound with Kondo scale $T_K \sim$ 15 K and shows an enhanced Sommerfeld coefficient of $γ_0 \sim$ 203 mJ/mol$\cdot$K$^{2}$. While no superconductivity can been observed down to 30 mK, Ce ions exhibit two successive antiferromagnetic (AFM) transitions. We propose that the magnetic moment of Ce ion could align in the G type AFM order below the first transition at $T_{N1}$=9.3 K, and it might be modified into the C type AFM order below a lower transition at $T_{N2}$=7.3 K. Our results indicate that the 3$d-4f$ interlayer Kondo interactions play an important role in Ni-based Ce-containing pnictide.

description: Die vorliegende Arbeit beschäftigt sich mit dem konzeptionellen Auf- und Ausbau der Offenen Jugendarbeit in den Gemeinden Erlinsbach Aargau und Erlinsbach Solothurn. In den beiden angrenzenden Gemeinden bestehen vielfältige Angebote für Kinder und Erwachsene. Die Jugendlichen befinden sich jedoch in einem Angebotsvakuum, welches mit dem Aufbau der Offenen Jugendarbeit aufgehoben werden soll. Die vorliegende Arbeit geht daher der Frage nach, welche Wissensgrundlagen anhand von ausgewählten Methoden einer Sozialraumanalyse erschlossen werden können, um die Jugendarbeit der Gemeinden Erlinsbach Solothurn und Erlinsbach Aargau aufzubauen und auszuarbeiten. Zur Beantwortung der Fragestellung, wird die sozialraumanalytische Methode der Institutionenbefragung angewandt. Ziel der Beantwortung der Fragestellung ist folglich, die Relevanz der genannten Methode für die professionelle Jugendarbeit festzustellen und dadurch einen Beitrag zum flächendeckenden Ausbau der Offenen Jugendarbeit in der Region zu leisten. Die Ergebnisse zeigen, dass die Methode eine solide Grundlage für die weitere Konzeptionalisierung der Offenen Jugendarbeit in den Gemeinden darstellt. Durch die Befragung konnten Defizite im Sozialraum der beiden Gemeinden deutlich hervorgehoben und Problemlagen der Jugendlichen festgestellt werden. Die Arbeit dient einer vertieften Auseinandersetzung mit dem Thema Jugendarbeit, wodurch die Relevanz der Begleitung und Unterstützung von Jugendlichen in ihrer Entwicklung für die Soziale Arbeit hervorgehoben wird.

description: Basierend auf einer wertneutralen Definition von Manipulation als Machtmittel in Beziehungen wird, ausgehend vom Kontext der stationären Betreuung von Menschen mit einer geistigen Behinderung analysiert, inwiefern Manipulation im professionellen Handeln von Sozialarbeitenden als Strategie der Beeinflussung potenziell genutzt wird. Darauf aufbauend werden sowohl Risiken wie auch Chancen von manipulativen Arbeitsweisen identifiziert, wofür Alexander Fischers Theorie und Ethik der Manipulation die Grundlage bietet. Um die Fragestellung nach der reflexiven Bewertung von Manipulation im professionellen Kontext zu beantworten, wird Fischers Fragekatalog geprüft und um, besonders für die Soziale Arbeit relevante, Zusatzfragen ergänzt. Angesichts des fehlenden Diskurses über das zwischenmenschliche Phänomen der Manipulation in der Sozialen Arbeit stellt die vorliegende Bachelor-Thesis eine erste Annäherung an das Thema dar. Sie hat zum Ziel, auf die vorhandene Diskurslücke hinzuweisen und weitere Auseinandersetzungen mit Manipulation in Wissenschaft und Praxis der Sozialen Arbeit anzuregen. So soll die Manipulation der professionellen Reflexion zugänglich gemacht werden, um eine diesbezügliche Qualitätssicherung von sozialen Dienstleistungen zu ermöglichen.

description: Employers are adopting algorithmic hiring technology throughout the recruitment pipeline. Algorithmic fairness is especially applicable in this domain due to its high stakes and structural inequalities. Unfortunately, most work in this space provides partial treatment, often constrained by two competing narratives, optimistically focused on replacing biased recruiter decisions or pessimistically pointing to the automation of discrimination. Whether, and more importantly what types of, algorithmic hiring can be less biased and more beneficial to society than low-tech alternatives currently remains unanswered, to the detriment of trustworthiness. This multidisciplinary survey caters to practitioners and researchers with a balanced and integrated coverage of systems, biases, measures, mitigation strategies, datasets, and legal aspects of algorithmic hiring and fairness. Our work supports a contextualized understanding and governance of this technology by highlighting current opportunities and limitations, providing recommendations for future work to ensure shared benefits for all stakeholders.

description: Mn-doped ZnO was synthesized using a co-precipitation technique. X-ray diffraction (XRD) measurements and photoluminescence (PL) spectra show that Mn ions are doped into the lattice positions of ZnO. The modes at 202, 330, and 437 cm-1 in the Raman spectrum are assigned as 2E2 (low), E2 (high)-E2 (low), and E2 (high) modes of ZnO base, respectively. The mode at 528 cm-1 is ascribed to a local vibrational mode related to Mn. The mode at 580 cm-1 should be an intrinsic mode of ZnO and assigned to E1 longitudinal optical (LO). Its reinforcement should result from a combination of resonance at the excitation wavelength and impurity-induced scattering.

Dazu wird in einem ersten Teil der Begriff der Resilienz und seinen Zusammenhang mit Risiko- und Schutzfaktoren erörtert und aufgezeigt, dass die Schutzfaktoren in Forschung und Praxis lange zu wenig Beachtung fanden. Im zweiten Teil ist die Funktionsweise und Arbeitspraxis im Berufsfeld Kinderschutz dargelegt mit einem besonderen Fokus auf die Kindeswohlabklärung, um dann in der darauffolgenden Analyse zu zeigen, inwiefern nicht nur Risikofaktoren, sondern auch Schutzfaktoren im Abklärungsprozess bei Verdacht auf Kindeswohlgefährdung (Fokus Basel-Stadt) bereits berücksichtigt werden. Es hat sich gezeigt, dass Schutzfaktoren bereits Beachtung finden, jedoch in ganz konkreten Bereichen der Kindeswohlabklärung (Bedarfsklärung, konkrete Interventionsempfehlungen) noch unzureichend berücksichtigt werden.

description: In der vorliegenden Bachelorarbeit setzte ich mich mit der Thematik der Selbstfürsorge auseinander. Die folgende Fragestellung soll damit beantwortet werden, inwiefern Selbstfürsorge als Konzept in den psychosozialen Tätigkeitsfeldern der Sozialen Arbeit zur Erhaltung der psychischen Gesundheit von Professionellen beitragen kann. Den Ausgangspunkt bildet die Tatsache, dass psychische Erkrankungen und Überbelastung bei Sozialarbeitenden vermehrt auftreten. Denn allein das Wissen darüber, dass ein Kind oder ein Jugendlicher eine traumatische Situation erleben musste, kann emotionale Reaktionen bei jedem Sozialpädagogen auslösen. Dadurch kann es sein, dass wir dann ähnliche Gefühle wie die Betroffenen erleben. Ziel dieser Arbeit ist, das Wissen und die Notwendigkeit der Selbstfürsorge zu erweitern und eigene Strategien für ein selbstfürsorgliches Verhalten aufzubauen, um den Herausforderungen des sozialpädagogischen Alltags standzuhalten.

description: We study collisions between two strongly interacting atomic Fermi gas clouds. We observe exotic nonlinear hydrodynamic behavior, distinguished by the formation of a very sharp and stable density peak as the clouds collide and subsequent evolution into a box-like shape. We model the nonlinear dynamics of these collisions using quasi-1D hydrodynamic equations. Our simulations of the time-dependent density profiles agree very well with the data and provide clear evidence of shock wave formation in this universal quantum hydrodynamic system.

description: Die Zahl der Asylgesuche in der Schweiz steigen an. Die Soziale Arbeit im Asylwesen ist konfrontiert mit traumatisierten geflüchteten Personen aus verschiedenen Ländern. Diese Arbeit befasst sich mit der Bedeutung der Kultur in der Kooperation mit traumatisierten geflüchteten Personen. Professionelle der Sozialen Arbeit sind in der Kooperation mit traumatisierten geflüchteten Personen gefordert einen adäquaten Umgang mit für sie fremden Kulturen, Werten, Ritualen und Sprachen zu finden. Durch den Einbezug von interkulturellen Ansätzen wird versucht, die Kooperation mit traumatisierten geflüchteten Personen methodisch zu gestalten. Es werden Annahmen getroffen, wie die Kultur den Umgang mit traumatisierenden Erlebnissen erleichtern oder erschweren kann und wie Professionelle der Sozialen Arbeit darauf reagieren können. Es wird zudem in nachfolgender Arbeit auf die Kernkompetenzen im Umgang mit traumatisierten Geflüchteten eingegangen. Das theoretische Wissen über deren Lebenslage und kulturellen Hintergrund und das praktische Wissen wie zum Beispiel über interkulturelle Kommunikationsmethoden gehören zu den Kernkompetenzen. Die Selbstreflexion spielt dabei eine bedeutende Rolle.

description: Let $\mathcal{C}_p$ be the Schatten $p$-class for $p>0$. Generalizations of the parallelogram law for the Schatten 2-norms have been given in the following form: If $\mathbf{A}=\{A_1,A_2,...,A_n\}$ and $\mathbf{B}=\{B_1,B_2,...,B_n\}$ are two sets of operators in $\mathcal{C}_2$, then $$\sum_{i,j=1}^n\|A_i-A_j\|_2^2 + \sum_{i,j=1}^n\|B_i-B_j\|_2^2 = 2\sum_{i,j=1}^n\|A_i-B_j\|_2^2 - 2\Norm{\sum_{i=1}^n(A_i-B_i)}_2^2.$$ In this paper, we give generalizations of this as pairs of inequalities for Schatten $p$-norms, which hold for certain values of $p$ and reduce to the equality above for $p=2$. Moreover, we present some related inequalities for three sets of operators.

description: We present energy-resolved measurements of electron emission from sharp metal tips driven with low energy pulses from a few-cycle laser oscillator. We observe above-threshold photoemission with a photon order of up to 9. At a laser intensity of 2*10^11 W/cm^2 suppression of the lowest order peak occurs, indicating the onset of strong-field effects. We also observe peak shifting linearly with intensity with a slope of around -1.8eV / (10^12 W/cm^2). We attribute the magnitude of the laser field effects to field enhancement taking place at the tip's surface.

We report our recent progress on those existing puzzles.

description: This thesis is focused on the articulation of Sheedi Identity in Digital Media. I examine three pieces of digital media from YouTube: a documentary titled “Kings without Thrones - Sheedi Badshah”, a documentary titled “Life Along the Coast,” but uploaded as “(Sheedi) Deeply Life of Pakistani Black People,” and an Instagram live interview titled “#BlackLivesMatter: The Pakistani context. My research questions are as follows: How do Sheedis understand their identity? How do Sheedis understand their identity in relation to Non-Sheedi Pakistani people? How do Sheedis understand their identity in relation to Africa and the Africa Diaspora in South Asia and beyond? In this study, I argue that Sheedis have multivalent identities; Sheedi identity is rooted in connections to an imagined Islamic past, notions of African heritage, and local Pakistani cultural contexts. Sheedis accept their Pakistani identity, Islamic heritages, and African heritages, while recognizing the precarious nature of their position in society due to legacies of racism and slavery.
Understanding the social determinants of substance use among pregnant-involved young Aboriginal women : a mixed methods research project
Creators: name: Shahram, Sana
Publisher: name: University of British Columbia
Year: 2015

description: There is a lack of research exploring the social, political and historical contexts of substance use during pregnancy among young Aboriginal women. Although Aboriginal women have been hyper-visible in policies and programming for substance use during pregnancy in Canada, there remains a dearth of information about Aboriginal women’s experiences with substance use and pregnancy in the published literature. In order to understand the social determinants of substance use during pregnancy from the perspective of young Aboriginal women themselves, a convergent mixed methods research project was conducted. The research project included a secondary data analysis (N=291), life history interviews (N=24), and an innovative pilot participant-generated mapping exercise called CIRCLES (Charting Intersectional Relationships in the Context of Life Experiences with Substances) developed by the author (N=17). The research project’s findings were integrated to inform the creation of a new wellness-focused model of the social determinants of substance use among pregnant-involved young Aboriginal women. The new model identifies several points of intervention for supporting women’s strengths, resilience and the maintenance of the mother-child unit to promote wellness among women. Further research is needed to test this new model among larger populations, and to identify specific resiliency factors to support Aboriginal mothers and their children.

description: We study the effect of hole doping on the Kitaev spin liquid (KSL) and find that for ferromagnetic (FM) Kitaev exchange $K$ the system is very susceptible to the formation of a FM spin polarization. Through density matrix renormalization group (DMRG) simulations on finite systems, we uncover that the introduction of a single hole with a hopping strength of just $t\sim{}0.28K$ is enough to disrupt fractionalization and polarize the spins in the [001] direction due to an order-by-disorder mechanism. Taking into account a material relevant FM anisotropic spin exchange $\varGamma$ drives the polarization towards the [111] direction via a reorientation transition into a topological FM state with chiral magnon excitations. We develop a parton mean-field theory incorporating fermionic holons and bosonic spinons/magnons, which accounts for the doping induced FM phases and topological magnon excitations. We discuss experimental signatures and implications for Kitaev candidate materials.

Mit Hilfe des biopsychosozialen Verständnisses von Krankheit, werden durch eine Literaturrecherche theoretische und empirische Wissensbestände ausgebreitet, verknüpft und diskutiert. Diese Arbeit kommt zum Resultat, dass es durch Bedürfnisspannungen, krisenhafte Ereignisse und das Vulnerabilitäts-Stress-Modell theoretische Erklärungsansätze gibt, welche die soziale Dimension und die Entstehung von Depressionen in einen Zusammenhang setzen. Empirisch finden sich ebenfalls Hinweise darauf. Diese Ergebnisse sind durch die allgemeine Forschungslücken der Thematik ‹Soziale Dimension und die Entstehung von Depressionen› kritisch zu betrachten. Im Allgemeinen bedarf es an flächendeckender Forschung zu diesem Bereich.

description: In this article, we present a new approach to averaging in non-Hamiltonian systems with periodic forcing. The results here do not depend on the existence of a small parameter. In fact, we show that our averaging method fits into an appropriate nonlinear equivalence problem, and that this problem can be solved formally by using the Lie transform framework to linearize it. According to this approach, we derive formal coordinate transformations associated with both first-order and higher-order averaging, which result in more manageable formulae than the classical ones. Using these transformations, it is possible to correct the solution of an averaged system by recovering the oscillatory components of the original non-averaged system. In this framework, the inverse transformations are also defined explicitly by formal series; they allow the estimation of appropriate initial data for each higher-order averaged system, respecting the equivalence relation. Finally, we show how these methods can be used for identifying and computing periodic solutions for a very large class of nonlinear systems with time-periodic forcing. We test the validity of our approach by analyzing both the first-order and the second-order averaged system for a problem in atmospheric chemistry.

description: Galaxy properties primarily depend on their host halo mass. Halo mass, in turn, depends on the cosmic web environment. We explore if the effect of the cosmic web on galaxy properties is entirely transitive via host halo mass, or if the cosmic web has an effect independent of mass. The secondary galaxy bias, sometimes referred to as ``galaxy assembly bias'', is the beyond-mass component of the galaxy-halo connection. We investigate the link between the cosmic web environment and the secondary galaxy bias in simulations. We measure the secondary galaxy bias through the following summary statistics: projected two-point correlation function, $\wprp$, and counts-in-cylinders statistics, $\Pncic$. First, we examine the extent to which the secondary galaxy bias can be accounted for with a measure of the environment as a secondary halo property. We find that the total secondary galaxy bias preferentially places galaxies in more strongly clustered haloes. In particular, haloes at fixed mass tend to host more galaxies when they are more strongly associated with nodes or filaments. This tendency accounts for a significant portion, but not the entirety, of the total secondary galaxy bias effect. Second, we quantify how the secondary galaxy bias behaves differently depending on the host halo proximity to nodes and filaments. We find that the total secondary galaxy bias is relatively stronger in haloes more associated with nodes or filaments. We emphasise the importance of removing halo mass effects when considering the cosmic web environment as a factor in the galaxy-halo connection.

description: We report the chiral quark model approach for the study of baryon resonances in meson photoproduction and meson-nucleon scattering processes. Focussing on the $πN$ and $K N$ scatterings, we show that the cross sections near threshold can be well accounted for by the chiral quark model with only few parameters. The $S$-wave dominance in both $π^- p\to ηn$ and $K^- p\to Σ^0π^0$ can be well understood in the quark model framework. In particular, the quark model provides a constraint on the relative signs for resonance coupling form factors, which seems to be consistent with results from isobaric models.

description: Im Zuge dieser Dissertationsschrift wurde die Polymerisation von BiEDOT in einem oxidativen Medium untersucht. Im synthetischen Bereich lag das Hauptaugenmerk hierbei sowohl auf der Aufreinigungsprozedur als auch auf der Optimierung des reinen Polymerisationsprozesses. Die Verbesserung der thermoelektrischen Eigenschaften der PEDOT-Beschichtungen dieser PEDOT-Fluide stand jedoch generell im Hauptfokus. Als Charakterisierung wurden die erhaltenen viskosen Flüssigkeiten als getrocknete Filme elektrisch und stellenweise auch thermoelektrisch charakterisiert.

Die dargestellten Fluide wurden anhand von zur Verfügung stehenden Labortechniken in den kg-Maßstab überführt. Diese Mengen wurden benötigt um die entwickelten PEDOT-Fluide für den sogenannten rotativen Siebdruck, einer Methode zur Flüssigprozessierung, zugänglich zu machen. Die Fluide wurden dann gemeinsam mit Wissenschaftlern des LTI des KITs und der otego GmbH an einer industriellen Rolle-zu-Rolle Druckmaschine verdruckt.
Ultrahigh energy cosmic ray acceleration in newly born magnetars and their associated gravitational wave signatures

description: Newly born magnetars are good candidate sources of ultrahigh energy cosmic rays. These objects can in principle easily accelerate particles to the highest energies required to satisfy the ultrahigh energy cosmic ray scenario (E~10^{20-21} eV), thanks to their important rotational and magnetic energy reservoirs. Their acceleration mechanism, based on unipolar induction, predicts however a hard particle injection that does not fit the observed ultrahigh energy cosmic ray spectrum. Here we show that an adequate distribution of initial voltages among magnetar winds can be found to soften the spectrum. We discuss the effect of these distributions for the stochastic gravitational wave background signature produced by magnetars. The magnetar population characteristics needed to fit the ultrahigh energy cosmic ray spectrum could lead in most optimistic cases to gravitational wave background signals enhanced of up to four orders of magnitudes in the range of frequency 1-100 Hz, compared to the standard predictions. These signals could reach the sensitivities of future detectors such as DECIGO or BBO.

On the scarcity of Magellanic Cloud-like satellites

description: We have used H alpha narrow-band imaging to search for star-forming satellite galaxies around 143 luminous spiral galaxies, with the goal of quantifying the frequency of occurrence of satellites resembling the Magellanic Clouds, around galaxies comparable to the Milky Way. For two-thirds of the central galaxies, no star-forming satellites are found, down to luminosities and star-formation rates well below those of the Magellanic Clouds. A total of 62 satellites is found, associated with 47 of the central galaxies searched. The R-band magnitude difference between central galaxies and their satellites has a median value of 4.6 mag, and a maximum of 10.2 mag. The mean projected separation of the satellites from their central galaxies is 81 kpc, or 98 kpc for systems beyond 30 Mpc. Thus star-forming satellites are quite rare, and the Milky Way is unusual both for the luminosity and the proximity of its two brightest satellites. We also find that the Clouds themselves are unusual in that they appear to form a bound binary pair; such close satellite pairs, of any luminosity, are also extremely rare in our survey.

Illuminating phylogeny and function of microbial dark matter in Sakinaw Lake
Creators: name: Gies, Esther Anna
Publisher: name: University of British Columbia

description: Microorganisms are the most abundant and diverse forms of life on Earth. Interconnected microbial communities drive matter and energy transformations integral to ecosystem functions and services through distributed metabolic networks innovated over 3.5 billion years of evolution. To effectively harness this metabolic potential it is necessary to chart uncultivated microbial community structure and function. Cultivation-independent studies indicate that over half of the microbial diversity on Earth belongs to uncultivated candidate divisions, also known as microbial dark matter (MDM). Here, I illuminate MDM structure and function in meromictic Sakinaw Lake on the Sunshine Coast of British Columbia Canada. Sakinaw Lake water column conditions quantified over 8 field campaigns were intimately associated with unprecedented abundance and diversity of MDM. Using network analysis and single cell genomics, co-occurrence patterns between MDM including OP9/JS-1, OP8 and methanogenic Archaea were linked with potential to perform syntrophic acetate oxidation, an important process in anaerobic digestion of organic matter in natural and engineered ecosystems. Single-cell and metagenome analysis revealed previously unrecognized nitrate reduction potential in candidate division OP3 and uncovered a novel archaeal lineage. In addition, numerous Fe-S oxidoreductases associated with MDM in Sakinaw Lake indicate the potential to couple sulfur oxidation to iron reduction. Taken together, my work establishes Sakinaw Lake as a natural laboratory in which to explore MDM structure and function, shines a spotlight on known and novel interactions and metabolic capabilities among these most enigmatic microorganisms, and points to potential biotechnological innovations based on cooperative interactions between MDM populations.

description: Superradiant instability turns rotating astrophysical black holes into unique probes of light axions. We consider what happens when a light axion is coupled to a strongly coupled hidden gauge sector. In this case superradiance results in an adiabatic increase of a hidden sector CP-violating $θ$-parameter in a near horizon region. This may trigger a first order phase transition in the gauge sector. As a result a significant fraction of a black hole mass is released as a cloud of hidden mesons and can be later converted into electromagnetic radiation. This results in a violent electromagnetic burst. The characteristic frequency of such bursts may range approximately from 100 eV to 100 MeV.

description: In this paper we study planar polynomial differential systems of this form: dX/dt=A(X, Y), dY/dt= B(X, Y), where A,B belongs to Z[X, Y], degA \leq d, degB \leq d, and the height of A and B is smaller than H. A lot of properties of planar polynomial differential systems are related to irreducible Darboux polynomials of the corresponding derivation: D =A(X, Y)dX + B(X, Y)dY . Darboux polynomials are usually computed with the method of undetermined coefficients. With this method we have to solve a polynomial system. We show that this approach can give rise to the computation of an exponential number of reducible Darboux polynomials. Here we show that the Lagutinskii-Pereira's algorithm computes irreducible Darboux polynomials with degree smaller than N, with a polynomial number, relatively to d, log(H) and N, binary operations. We also give a polynomial-time method to compute, if it exists, a rational first integral with bounded degree.

description: We have recently proposed a new method for charging Li-ion batteries based on large-scale molecular dynamics studies (I. Abou Hamad et al, Phys. Chem. Chem. Phys., 12, 2740 (2010)). Applying an additional oscillating electric field in the direction perpendicular to the graphite sheets of the anode showed an exponential decrease in charging time with increasing amplitude of the applied oscillating field. Here we present new results exploring the effect on the charging time of changing the orientation of the oscillating field. Results for oscillating fields in three orthogonal directions are compared.

description: We analyze the macroscopic dynamics of a Bose gas axially confined in an optical lattice with a superimposed harmonic trap, taking into account weak tunneling effect. Our results show that upon transition to the quasi-two-dimensional (2D) regime of the trapped gas, the 3D equation of state and equilibrium density profile acquire corrections from 2D many-body effects. The corresponding frequency shift in the transverse breathing mode is accessible within current facilities, suggesting a direct observation of dimensional effects. Comparisons with other relevant effects are also presented.
