description: Nanocatalysis is swiftly mounting in various catalyzed organic reactions. Nowadays a wide variety of nano sized species such as nanoparticles or nanocomposites are effectively employed as catalyst. Conventionally noble metals such as Pt, Pd, Rh and Au are used in various heterogeneous catalytic reductions in organic chemistry. Heterogeneous hydrogenation catalysis is highly desirable since in this stage the important enantio-differentiating step is happening at the metal surface. In this review, we try to underscore the recent development of using the traditional noble metals in their nano forms as nanocatalysts in the reduction of nitroarenes such as 4-nitrophenol (4-NP) and related compounds to their corresponding amino derivatives.

description: This paper studies the economic utilities and the quality of service (QoS) in a two-sided non-neutral market where Internet service providers (ISPs) charge content providers (CPs) for the content delivery. We propose new models on a two-sided market which involves a CP, an ISP, end users and advertisers. The CP may have either the subscription revenue model (charging end users) or the advertisement revenue model (charging advertisers). We formulate the interactions between the ISP and the CP as a noncooperative game problem for the former and an optimization problem for the latter. Our analysis shows that the revenue model of the CP plays a significant role in a non-neutral Internet. With the subscription model, both the ISP and the CP receive better (or worse) utilities as well as QoS in the presence of side payment at the same time. However, with the advertisement model, the side payment impedes the CP from investing on its contents.

description: We quantify our current knowledge of the size and flavor structure of the matter effects in the evolution of atmospheric and long-baseline neutrinos based solely on the analysis of the corresponding neutrino data. To this aim we generalize the matter potential of the Standard Model by rescaling its strength, rotating it away from the e-e sector, and rephasing it with respect to the vacuum term. This phenomenological parametrization can be easily translated in terms of non-standard neutrino interactions in matter. We show that in the most general case, the strength of the potential cannot be determined solely by atmospheric and long-baseline data. However its flavor composition is very much constrained and the present determination of the neutrino masses and mixing is robust under its presence. We also present an update of the constraints arising from this analysis in the particular case in which no potential is present in the e-mu and e-tau sectors. Finally we quantify to what degree in this scenario it is possible to alleviate the tension between the oscillation results for neutrinos and antineutrinos in the MINOS experiment and show the relevance of the high energy part of the spectrum measured at MINOS.

description: We have measured the quantum Hall activation gaps in bilayer graphene at filling factors $ν=\pm4$ and $ν=\pm8$ in high magnetic fields up to 30 T. We find that energy levels can be described by a 4-band relativistic hyperbolic dispersion. The Landau level width is found to contain a field independent background due to an intrinsic level broadening and a component which increases linearly with magnetic field.

description: In the conventional formulation, it is broadly accepted that simultaneous measurability and commutativity of observables are equivalent. However, several objections have been claimed that there are cases in which even nowhere commuting observables can be measured simultaneously. Here, we outline a new theory of simultaneous measurements based on a state-dependent formulation, in which nowhere commuting observables are shown to have simultaneous measurements in some states, so that the known objections to the conventional theory are theoretically justified. We also discuss new results on the relation between weak values and output probability distributions of simultaneous measurements.

description: We study the chiral phase transition in a magnetic field at finite temperature and chemical potential within the Sakai-Sugimoto model, a holographic top-down approach to (large-N_c) QCD. We consider the limit of a small separation of the flavor D8-branes, which corresponds to a dual field theory comparable to a Nambu-Jona Lasinio (NJL) model. Mapping out the surface of the chiral phase transition in the parameter space of magnetic field strength, quark chemical potential, and temperature, we find that for small temperatures the addition of a magnetic field decreases the critical chemical potential for chiral symmetry restoration - in contrast to the case of vanishing chemical potential where, in accordance with the familiar phenomenon of magnetic catalysis, the magnetic field favors the chirally broken phase. This "inverse magnetic catalysis" (IMC) appears to be associated with a previously found magnetic phase transition within the chirally symmetric phase that shows an intriguing similarity to a transition into the lowest Landau level. We estimate IMC to persist up to 10^{19} G at low temperatures.

title: Common cents: the experiences of low-income students in high-profile conservatoires
Creators: name: Morgan, F.
Publisher: name: Royal College of Music
Year: 2020

description: Conservatoires are elite institutions – both in the talent that they attract and in the lack of diversity that they represent. In 2018, the Higher Education Statistics Agency reported that conservatoires have nearly double the number of private school students as leading institutions the University of Oxford and University of Cambridge. Furthermore, only 3.9% of conservatoire students come from low-participation neighbourhoods. There is limited literature examining how low-income students, once within the four walls of a conservatoire, may interact with their environment. This study was a responsive investigation that qualitatively gathered insights on subtle barriers and cultural perceptions that these low-income students may experience while studying at conservatoire. This study also aimed to determine whether Whatsapp was an effective data collection tool when working with marginalised social groups. Four participants were interviewed via Whatsapp Voice Note recordings in a semi-structured interview format. This format, and the Whatsapp Voice Note recordings, successfully helped redress the power balance between the researcher and the participant. Data was analysed using Interpretative Phenomenological Analysis (IPA) and results indicated five superordinate themes: elitism in Classical music education; the ‘self-conscious outsider’; work as an obstacle to study and attainment; an enjoyable conservatoire experience, and; the international experience. These findings suggested a mixed experience for the four participants, who had encountered practical and conceptual disadvantages such as affording their instrument, the need for code switching, and a lack of institutional acknowledgement that there was an issue with low-incomes students affording their studies. Conditional to further research informing these findings, the main implications of this study were suggested changes to financial, registry, and programming policy in conservatoire. This study opted for socioeconomic terminology over class system terminology (e.g. ‘low-income’ instead of ‘working-class’). While there is significant financial and cultural overlap between these two groups in the results, it is important to note that this study is implicated by its focus on financial hardship and not by wider interactions of the British class system.

description: High-multiplicity proton-proton collisions at the LHC may exhibit collective phenomena such as elliptic flow. We study this issue using DIPSY, a brand-new Monte Carlo event generator which features almost-NLO BFKL dynamics and describes the transverse shape of the proton including all fluctuations. We predict the eccentricity of the collision as a function of the multiplicity and estimate the magnitude of elliptic flow. We suggest that flow can be signaled by a sign change in the four-particle azimuthal correlation.

Feasibility of a pilot study to assess the safety and antipyretic efficacy of acetaminophen in critically ill patients.
Creators: name: Bains, Vininder Kour
Publisher: name: University of British Columbia
Year: 2017

description: Preliminary, mostly small observational studies, suggest that febrile intensive care unit (ICU) patients may be at higher risk of acetaminophen-associated hypotension and that acetaminophen may be a less effective antipyretic in this population than previously thought. A pilot double-blinded, randomized controlled trial was conducted to examine four questions: (a) what is the feasibility of conducting this study, (b) is there a difference in incidence of clinically significant hypotensive events, and/or blood pressure in the four hours post intervention between febrile, non-brain injured patients who received either a single dose acetaminophen or a placebo, (c) is there a difference in fever burden between participants who received the treatment versus placebo, and (d) what are the relationships between heart rate, blood pressure, core temperature, and fever burden? Over nine months, 83% of the 950 admitted ICU patients were screened, 100 patients were eligible but due to logistical challenges, only 27 were invited to participate, of which 17 refused. Only six of the 10 participants completed the study, and of those five were randomized to the acetaminophen group. The eligibility rate increased from 10.0% to 16.3% (p = 0.016) after small changes to the inclusion criteria were made. The sample size was too small to draw conclusions regarding the utility of outcome measures, participant safety, or the hemodynamic or antipyretic effects of acetaminophen; however, no participant had a safety event. Participants had variable heart rate, blood pressure, and fever patterns. There was little or no discernable antipyretic effect of acetaminophen in the five participants who received the drug. Additionally, strong linear relationships were detected between mean pre-post intervention differences in fever burden and mean arterial pressure (MAP) as well as core temperature and heart rate (p = 0.003 for both). Mean difference in MAP increased by 2.20 mmHg for every 1 °C-hour increase in net change in fever burden (R² = 0.906; 95% C I [1.214, 3.186]). Mean difference in heart rate increased by 4.840 beats/minute for every 1 °C increase in mean difference in core temperature (R² = 0.905; 95% CI [2.665, 7.014]).

description: There has been a controversy as to whether or not the non-pathological flat foot and high-arched foot have an effect on human walking activities. The 3D foot scanning system was employed to obtain static footprints from subjects adopting a half-weight-bearing stance. Based upon their footprints, the subjects were divided into two groups: the flat-footed and the high-arched. The plantar pressure measurement system was used to measure and record the subjects' successive natural gaits. Two indices were proposed: distribution of vertical ground reaction force (VGRF) of plantar and the rate of the footprint areas. Using these two indices to compare the natural gaits of the two subject groups, we found that (1) in stance phase, there is a significant difference (p<0.01) in the distributions of VGRF of plantar; (2) in a stride cycle, there is also a significant difference (p<0.01) in the rates of the footprint areas. Our analysis suggests that when walking, the VGRF of the plantar brings greater muscle tension to the flat-footed while a smaller rate of the footprint areas brings greater stability to the high-arched.

(A) Estimated distributions for transcript abundances overlapping intronic regions in the sense orientation (left panel), intronic regions in the antisense orientation (middle panel), and intergenic regions (right panel). (B) Estimated distributions for transcript- and gene-level abundances. Gene-level abundances are calculated by summing the abundances of all transcripts belonging to each gene. (C) Estimated distributions for per-transcript PSI (percent splicing included) values. Data in this figure are for transcripts from genes estimated to express at least one splice form. (D) Estimated distributions for allelic imbalance, represented as the ratio of molecules transcribed from the parent 1 allele and the parent 2 allele. The Y-axes for all plots display the Gaussian kernel density estimates calculated by the density() function in R. The X-axes in panels (A) and (B) display the log10-transformed abundance estimates for each genomic feature in FPK (fragments per kilobase length), a length-normalized measure of transcript abundance. For display purposes, a pseudocount of 0.001 was added to each FPK value, so that features with an FPK of 0 are still displayed in log10 space at the position log10(0 + 0.001) = -3. CAMPAREE estimated these distributions from two real mouse liver RNA-Seq samples (9575 - GSM2599715; 9577 - GSM2599721).

description: We present four continuations of the critical nonlinear \schro equation (NLS) beyond the singularity: 1) a sub-threshold power continuation, 2) a shrinking-hole continuation for ring-type solutions, 3) a vanishing nonlinear-damping continuation, and 4) a complex Ginzburg-Landau (CGL) continuation. Using asymptotic analysis, we explicitly calculate the limiting solutions beyond the singularity. These calculations show that for generic initial data that leads to a loglog collapse, the sub-threshold power limit is a Bourgain-Wang solution, both before and after the singularity, and the vanishing nonlinear-damping and CGL limits are a loglog solution before the singularity, and have an infinite-velocity{\rev{expanding core}} after the singularity. Our results suggest that all NLS continuations share the universal feature that after the singularity time $T_c$, the phase of the singular core is only determined up to multiplication by $e^{iθ}$. As a result, interactions between post-collapse beams (filaments) become chaotic. We also show that when the continuation model leads to a point singularity and preserves the NLS invariance under the transformation $t\rightarrow-t$ and $ψ\rightarrowψ^\ast$, the singular core of the weak solution is symmetric with respect to $T_c$. Therefore, the sub-threshold power and the{\rev{shrinking}}-hole continuations are symmetric with respect to $T_c$, but continuations which are based on perturbations of the NLS equation are generically asymmetric.

description: The structural and magnetic phase transitions have been studied on NdFeAsO single crystals by neutron and x-ray diffraction complemented by resistivity and specific heat measurements. Two low-temperature phase transitions have been observed in addition to the tetragonal-to-orthorhombic transition at T_S = 142 K and the onset of antiferromagnetic (AFM) Fe order below T_N = 137 K. The Fe moments order AFM in the well-known stripe-like structure in the (ab) plane, but change from AFM to ferromagnetic (FM) arrangement along the c direction below T* = 15 K accompanied by the onset of Nd AFM order below T_Nd = 6 K with this same AFM configuration. The iron magnetic order-order transition in NdFeAsO accentuates the Nd-Fe interaction and the delicate balance of c-axis exchange couplings that results in AFM in LaFeAsO and FM in CeFeAsO and PrFeAsO.

description: Additional file 6: Figure S5. Transcript abundances simulated by BEERS, Polyester, and RSEM after being primed with CAMPAREE output. Scatterplots of transcript abundances simulated by BEERS (left panels), Polyester (middle panels), and RSEM (right panels), compared to CAMPAREE abundances used to prime each RNA-Seq simulator. Data are displayed separately for genes from each parental allele (top and bottom panels). The line of unexpressed transcripts at the bottom of the BEERS panels are from transcripts which BEERS removed from the annotation because they possess genomic features which interfere with BEERS’s underlying simulation (e.g., length < 200 bp, introns < 10 bp). Similarly, the unexpressed transcripts from the bottom of the RSEM panels are from short transcripts. RSEM reads transcript abundances as TPM (transcripts per million) values. The TPM calculation involves calculating a transcript’s “effective length,” by subtracting the estimated RNA-Seq read/fragment length from the transcript’s length. This can result in an effective length < 0 for short transcripts. In the RSEM model, transcripts with effective lengths < 0 have no expression. The X- and Y-axes display the transcript abundances simulated by each RNA-Seq simulator and by CAMPAREE, respectively. For display purposes, a pseudocount of 0.1 was added to each abundance value, so unexpressed transcripts are still displayed in log10 space at the position log10(0 + 0.1) = -1.

description: A method to calculate light curves of the gravitational microlensing of the Ellis wormhole is derived in the weak-field limit. In this limit, lensing by the wormhole produces one image outside the Einstein ring and one other image inside. The weak-field hypothesis is a good approximation in Galactic lensing if the throat radius is less than $10^{11} km$. The light curves calculated have gutters of approximately 4% immediately outside the Einstein ring crossing times. The magnification of the Ellis wormhole lensing is generally less than that of Schwarzschild lensing. The optical depths and event rates are calculated for the Galactic bulge and Large Magellanic Cloud fields according to bound and unbound hypotheses. If the wormholes have throat radii between 100 and $10^7 km$, are bound to the galaxy, and have a number density that is approximately that of ordinary stars, detection can be achieved by reanalyzing past data. If the wormholes are unbound, detection using past data is impossible.

description: A Lagrangian derivation of the Equation of Motion (EOM) for static spherically symmetric metrics in F(R) modified gravity is presented. For a large class of metrics, our approach permits to reduce the EOM to a single equation and we show how it is possible to construct exact solutions in $F(R)$-gravity. All known exact solutions are recovered. We also exibit a new non trivial solution with non constant Ricci scalar.

description: We perform a systematic analysis of an extension of the Standard Model that includes a complex singlet scalar field and is scale invariant at the tree level. We call such a model the Minimal Scale Invariant extension of the Standard Model (MSISM). The tree-level scale invariance of the model is explicitly broken by quantum corrections, which can trigger electroweak symmetry breaking and potentially provide a mechanism for solving the gauge hierarchy problem. Even though the scale invariant Standard Model is not a realistic scenario, the addition of a complex singlet scalar field may result in a perturbative and phenomenologically viable theory. We present a complete classification of the flat directions which may occur in the classical scalar potential of the MSISM. After calculating the one-loop effective potential of the MSISM, we investigate a number of representative scenarios and determine their scalar boson mass spectra, as well as their perturbatively allowed parameter space compatible with electroweak precision data. We discuss the phenomenological implications of these scenarios, in particular, whether they realize explicit or spontaneous CP violation, neutrino masses or provide dark matter candidates. In particular, we find a new minimal scale-invariant model of maximal spontaneous CP violation which can stay perturbative up to Planck-mass energy scales, without introducing an unnaturally large hierarchy in the scalar-potential couplings.

Description of the cophylogenetic relationship between the Myrsidea chewing louse and its Neotropical Mionectes flycatcher host.
Creators: name: Cook, Andrew
Publisher: name: University of British Columbia
Year: 2017

description: Cospeciation is when two species share similar or identical phylogenies as a result of their interactions and is often predicted with ectosymbionts, organisms that complete the majority of their lifecycle on a host. When an organism is dependent on another to complete it’s reproductive cycle, there is potential for cospeciation. Due to limited dispersal capabilities beyond contact between a current and potential host species, many ectosymbionts have phylogenies that mirror their hosts’. In this thesis, I test this prediction using Myrsidea feather lice found on Neotropical Mionectes flycatchers from Manu National Park, Peru. My results show strong evidence of cospeciation by comparing trees built using sequences from the Myrsidea’s mitochondrial (CO1) and nuclear (EF-1α) genes to previously described host trees from Miller et al. (2008) and Jetz et al. (2012). These findings agree with previous morphological descriptions of two Myrsidea lice species co-occurring with Mionectes hosts and provides evidence that there are currently two previously undescribed species of Myrsidea. This adds to our knowledge and understanding of how ectosymbionts and hosts interact through evolutionary time, and provides the basis for future studies on the description of Myrsidea which is an under-described group of widespread organisms.

description: The magnetization and anisotropic electrical transport properties have been measured in high quality Cu0.03TaS2 single crystal. A pronounced peak effect has been observed, indicating that the high quality and homogeneity are vital to peak effect. A kink has been observed in the magnetic field H dependence of the in-plane resistivity ρab for H || c, which corresponds to a transition from activated to diffusive behavior of vortex liquid phase. In the diffusive regime of the vortex liquid phase, the in-plane resistivity ρab shows ρab $\propto$ H0.3 relation, which does not follow the Bardeen-Stephen law for free flux flow. Finally, a simplified vortex phase diagram of Cu0.03TaS2 for H || c is given.

description: In a recent experiment, a Bose-Einstein condensate of Li7 has been excited by a harmonic modulation of the atomic s-wave scattering length via Feshbach resonance. By combining an analytical perturbative approach with extensive numerical simulations we analyze the emerging nonlinear dynamics of the system on the mean-field Gross-Pitaevskii level at zero temperature. Resulting excitation spectra are presented and prominent nonlinear features are found: mode coupling, higher harmonics generation and significant shifts in the frequencies of collective modes. We indicate how nonlinear dynamical properties could be made clearly observable in future experiments and compared to our results.

Unearthing the influence of soil organic matter removal on population structure and metabolism of soil microbial communities
Creators: name: Hahn, Aria Stefanee
Publisher: name: University of British Columbia
Year: 2017

description: Microorganisms are the stewards and creators of Earth's ecosystems, driving planetary nutrient and energy cycles. As such, the interactions and metabolic processes of microbial communities have emerged as a fundamental area of scientific research. Through the use of multi-omic (e.g.; metagenomics, metatranscriptomics, proteomics) sequence information, it is possible to reconstruct the compositional, regulatory, and distributed metabolic processes connecting microbial community members. This dissertation develops an interpretative framework for the joint analysis of compositional network patterns and metabolic pathway reconstruction using metagenomic and metatranscriptomic data from soils collected from lodgepole pine forests 13 years post-harvesting and soil organic matter removal and adjacent undisturbed lodgepole pine forests and Interior Douglas-fir forests at two Long Term Soil Productivity (LTSP) sites located near Kamloops, and Williams Lake B.C., Canada. Further, this dissertation serves to improve the accuracy with which environmental sequence data are analyzed by leveraging the work of statisticians to overcome known biases in canonical approaches to data normalization. Finally, this work provides a systematic approach to the functional annotation of unassembled data, and extends an existing diversity index to accept data types common in studies involving uncultivated microbial annotation. Together the data indicated spatiotemporal variation in, and forest harvesting impact on, metabolic interactions and genomic potential for plant biomass degradation and carbon cycling. However, redundant metabolic capacity combined with genetic variation within the microbial community ensures natural and anthropogenically-induced environmental change had disparate effects across community members thereby moderating the consequences of localized extinctions or niche space reduction, and guarding against the loss of metabolic functions within the soil ecosystem. Indeed, environmental change can result in the reshuffling of trophic relationships and information exchange (e.g.; H+, metabolites, and horizontal gene transfer) allowing new and novel interactions between organisms to form and increase the community's ability to tolerate disturbance. This work represents an important step in understanding how environmental changes impact microbial communities and ecosystem function within the soil milieu. Ultimately, data and findings from this dissertation can be integrated with future analyses of biogeochemical parameter information and thermodynamic principles to enable time variable forecasts of microbial adaptive response to environmental change.

description: We calculate the rates for the charged lepton flavour violating (LFV) decays l_i -> l_j gamma, tau -> l pi, tau -> l eta('), mu^- -> e^-e^+e^-, the six three-body leptonic decays tau^- -> l_i^- l_j^+ l_k^- and the rate for mu-e conversion in nuclei in the Standard Model (SM3) extended by a fourth generation of quarks and leptons (SM4), assuming that neutrinos are Dirac particles. We also calculate branching ratios for K_L -> mu e, K_L -> pi^0 mu e, B_{d,s} -> mu e, B_{d,s} -> tau e and B_{d,s} -> tau mu. We find that the pattern of the LFV branching ratios in the SM4 differs significantly from the one encountered in the MSSM, allowing to distinguish these two models with the help of LFV processes in a transparent manner. Also differences with respect to the Littlest Higgs model with T-parity are found. Most importantly the branching ratios for l_i -> l_j gamma, tau -> l pi, tau -> l eta('), mu^- -> e^-e^+e^-, tau^- -> e^-e^+e^-, tau^- -> mu^- mu^+ mu^-, tau^- -> e^- mu^+ mu^- and tau^- -> mu^- e^+ e^- can all still be as large as the present experimental upper bounds but not necessarily simultaneously. Also the rate for mu-e conversion in nuclei can reach the corresponding upper bound.
