Scaling Behavior of Quantum Nanosystems: Emergence of Quasi-particles, Collective Modes, and Mixed Exchange Symmetry States

description: Quantum nanosystems such as graphene nanoribbons or superconducting nanoparticles are studied via a multiscale approach. Long space-time dynamics is derived using a perturbation expansion in the ratio of the nearest-neighbor distance to a nanometer-scale characteristic length, and a theorem on the equivalence of long-time averages and expectation values. This dynamics is shown to satisfy a coarse-grained wave equation (CGWE) which takes a Schrödinger-like form with modified masses and interactions. The scaling of space and time is determined by the orders of magnitude of various contributions to the N-body potential. If the spatial scale of the coarse-graining is too large, the CGWE would imply an unbounded growth of gradients; if it is too short, the system's size would display uncontrolled growth inappropriate for the bound states of interest, i.e., collective motion or migration within a stable nano-assembly. The balance of these two extremes removes arbitrariness in the choice of the scaling of space-time. Since the long-scale dynamics of each fermion involves its interaction with many others, we hypothesize that the solutions of the CGWE have mean-field character to good approximation, i.e., can be factorized into single-particle functions. This leads to a Coarse-grained Mean-field (CGMF) approximation that is distinct in character from traditional Hartree-Fock theory. A variational principle is used to derive equations for the single-particle functions. This theme is developed and used to derive an equation for low-lying disturbances from the ground state corresponding to long wavelength density disturbances or long-scale migration. An algorithm for the efficient simulation of quantum nanosystems is suggested.

description: We investigate existence and stability of viscoelastic shock profiles for a class of planar models including the incompressible shear case studied by Antman and Malek-Madani. We establish that the resulting equations fall into the class of symmetrizable hyperbolic--parabolic systems, hence spectral stability implies linearized and nonlinear stability with sharp rates of decay. The new contributions are treatment of the compressible case, formulation of a rigorous nonlinear stability theory, including verification of stability of small-amplitude Lax shocks, and the systematic incorporation in our investigations of numerical Evans function computations determining stability of large-amplitude and or nonclassical type shock profiles.

Subjects: Cancer

description: The clinical management of HER2+ breast cancer, which comprises approximately 20% of all breast cancer cases, has improved substantially by the use of targeted therapies. However, not all patients receiving neoadjuvant treatment achieve a pathological complete response(pCR), and the ability to identify responders could improve personalisation of treatment and patient stratification. In this work, specific immune cells of the tumour microenvironment are investigated in HER2+ breast tumour samples of the neoadjuvant TCHL clinical trial (NCT01485926)to evaluate their potential as biomarkers of response to neoadjuvant HER2-targetting therapy.To identify immune and stromal cells, and checkpoint proteins,in HER2+ breast tumours, three chromogenic and three fluorescent multiplex immunohistochemistry panels were successfully designed and optimised in formalin-fixed paraffin embedded tonsil and test breast tissue of the adjuvant St Vincent’s University Hospital cohort. Primary antibodies demonstrated specificity on negative control formalin-fixed paraffin embedded cell pellets. Two chromogenic panels targeting CD3+ T-cells, CD20+ B-cells, and DC-Lamp+ mature dendritic cells (tertiary lymphoid structure panel) and CD4+ helper T-cells and CD8+ cytotoxic T-cells (T-cell panel) were applied to pre-and post-treatment TCHL patient tumours. Analysis of multiplex stained patient samples was performed using Aiforia artificial intelligence software. Two separate models were trained and validated for the analysis of the tertiary lymphoid structure panel and T-cell panel staining on TCHL tumours, with error rates of 12.08% and 13.4%, respectively. Correlation of identified immune subpopulations with clinical parameters in pre-treatment TCHL patient biopsies revealed a significantly higher density of CD3+ T-cells (p = 0.043) and higher B-cell, helper T-cell, cytotoxic T-cell and dendritic cell densities in patients achieving a pCR vs. non-pCR patients. Evaluation of pre-treatment immune cell density with clinicopathological features demonstrated higher CD4+ and CD8+ T-cells in stage III vs. stage II patients, while significantly higher CD8+ T-cells (p = 0.026) and higher densities of B-cells, CD4+ T-cells, and dendritic cells were observed in estrogen receptor negative patients. In summary, this study identifies T-cells, B-cells and dendritic cells as predictors of achieving a pCR in neoadjuvant HER2+ BC, and highlights that therapeutic response may be influenced by hormone receptor status.

description: The development of innovative terahertz (THz) imaging systems has recently moved in the focus of scientific efforts due to the ability to screen substances through textiles or plastics. The invention of THz imaging systems with high spatial resolution is of increasing interest for applications in the realms of quality control, spectroscopy in dusty environment and security inspections. One of the main restrictions of current THz imaging systems is the low spatial resolution which is limited by a lack of THz lenses with strong focusing capabilities. Here we present the design, fabrication and the measurement of the optical properties of spectrally broadband metamaterial-based gradient index (GRIN) lenses that allow one to focus THz radiation to a spot diameter smaller than the wavelength. Due to the subwavelength thickness and the high focusing strength the presented GRIN lenses are an important step towards compact THz imaging systems with strongly improved spatial resolution.

description: Theoretical cross sections for the pressure broadening by hydrogen of rotational transitions of water are compared to the latest available measurements in the temperature range 65-220 K. A high accuracy interaction potential is employed in a full close coupling calculation. A good agreement with experiment is observed above ~80 K while the sharp drop observed experimentally at lower temperatures is not predicted by our calculations. Possible explanations for this discrepancy include the failure of the impact approximation and the possible role of ortho-to-para conversion of H2.

description: Photosynthetic pigments in plants comprise of chlorophylls a and b, which mainly capture light in the antenna complex via photosystem II, with subsequent electron transport. The two chlorophylls differ only at position 3 (ring B): chlorophyll a contains a methyl group at this position, whereas chlorophyll b contains an aldehyde group. Other pigments such as carotenoids are also found in plants and are considered as accessory components in the photosynthetic complex by providing photoprotection and stability of proteins present in the photosystem. To measure the chlorophyll content, we used a modified protocol (Arnon. 1949, Mochizuki et al., 2001). Extraction and determination of chlorophyll and carotenoid content was performed according to the method of Arnon (1949).

Real-time predictions from unlabeled high-dimensional sensory data during non-prehensile manipulation
Creators: name: Troniak, Daniel Michael
Publisher: name: University of British Columbia
Year: 2014

description: Robots can be readily equipped with sensors that span a growing range of modalities and price-points. However, as sensors increase in number and variety, making the best use of the rich multi-modal sensory streams becomes increasingly challenging. In this thesis, we demonstrate the ability to make efficient and accurate task-relevant predictions from unlabeled streams of sensory data for a non-prehensile manipulation task. Specifically, we address the problem of making real-time predictions of the mass, friction coefficient, and compliance of a block during a topple-slide task, using an unlabeled mix of 1650 features composed of pose, velocity, force, torque, and tactile sensor data samples taken during the motion. Our framework employs a partial least squares (PLS) estimator as computed based on training data. Importantly, we show that the PLS predictions can be made significantly more accurate and robust to noise with the use of a feature selection heuristic, the task variance ratio, while using as few as 5% of the original sensory features. This aggressive feature selection further allows for reduced bandwidth when streaming sensory data and reduced computational costs of the predictions. We also demonstrate the ability to make online predictions based on the sensory information received to date. We compare PLS to other regression methods, such as principal components regression. Our methods are tested on a WAM manipulator equipped with either a spherical probe or a BarrettHand with arrays of tactile sensors.

We measure tau(Bs) = 1.518 +/- 0.041 (stat.) +/- 0.027 (syst.) ps. The ratio of this result and the world average B0 lifetime yields tau(Bs)/tau(B0) = 0.99 +/-0.03, which is in agreement with recent theoretical predictions.

description: The advent of large instantaneous bandwidth receivers and high spectral resolution spectrometers on (sub-)millimeter telescopes has opened up the possibilities for unbiased spectral surveys. Because of the large amount of data they contain, any analysis of these surveys requires dedicated software tools. Here we present an extension of the widely used CLASS software that we developed to that purpose. This extension, named Weeds, allows for searches in atomic and molecular lines databases (e.g. JPL or CDMS) that may be accessed over the internet using a virtual observatory (VO) compliant protocol. The package permits a quick navigation across a spectral survey to search for lines of a given species. Weeds is also capable of modeling a spectrum, as often needed for line identification. We expect that Weeds will be useful for analyzing and interpreting the spectral surveys that will be done with the HIFI instrument on board Herschel, but also observations carried-out with ground based millimeter and sub-millimeter telescopes and interferometers, such as IRAM-30m and Plateau de Bure, CARMA, SMA, eVLA, and ALMA.

description: The vacuum expectation value of the energy-momentum tensor and the Casimir forces are investigated for a massive scalar field with an arbitrary curvature coupling parameter in the geometry of two parallel plates, on the background of de Sitter spacetime. The field is prepared in the Bunch--Davies vacuum state and is constrained to satisfy Robin boundary conditions on the plates. The vacuum energy-momentum tensor is non-diagonal, with the off-diagonal component corresponding to the energy flux along the direction normal to the plates. It is shown that the curvature of the background spacetime decisively influences the behavior of the Casimir forces at separations larger than the curvature radius of de Sitter spacetime. In dependence of the curvature coupling parameter and the mass of the field, two different regimes are realized, which exhibit monotonic or oscillatory behavior of the forces. The decay of the Casimir force at large plate separation is shown to be power-law, with independence of the value of the field mass.

description: The results of a theoretical investigation on the low-velocity stopping power of the ions moving in a magnetized collisional plasma are presented. The stopping power for an ion is calculated employing linear response theory using the dielectric function approach. The collisions, which leads to a damping of the excitations in the plasma, is taken into account through a number-conserving relaxation time approximation in the linear response function. In order to highlight the effects of collisions and magnetic field we present a comparison of our analytical and numerical results obtained for a nonzero damping or magnetic field with those for a vanishing damping or magnetic field. It is shown that the collisions remove the anomalous friction obtained previously [Nersisyan et al., Phys. Rev. E 61, 7022 (2000)] for the collisionless magnetized plasmas at low ion velocities. One of major objectives of this study is to compare and contrast our theoretical results with those obtained through a novel diffusion formulation based on Dufty-Berkovsky relation evaluated in magnetized one-component plasma models framed on target ions and electrons.

Quantifying the mineral carbonation potential of mine waste material : a new parameter for geospatial estimation
Creators: name: Jacobs, Anthony David
Publisher: name: University of British Columbia
Year: 2014

description: Direct aqueous mineral carbonation is a CO₂ sequestration method that can trap anthropogenic carbon dioxide as a thermodynamically stable carbonate. Ultramafic rocks considered waste at mining operations are targeted as the substrate source for carbonation in this research. Using mining waste to permanently fix CO₂ is a motivating factor for promoting industrial mineral carbonation as a viable carbon sequestration option. Experimental direct aqueous mineral carbonation was carried out on proposed Turnagain waste rock, a low-grade, high tonnage nickel sulphide deposit in northern British Columbia. 45 % magnesium silicate to magnesium carbonate conversion was achieved in two hours. The successful sequestration of CO₂ using mining waste rock and the opportunity of shared mining and mineral processing costs of a dual mining/mineral carbonation operation can aid in reducing economic and energy requirements, identified as key inhibiting factors of industrial mineral carbonation. The heterogenous mineralogy of ultramafic deposits commonly hosting mining operations makes quantifying the mineral carbonation potential (MCP) of the waste rock challenging. The MCP calculator, a novel Microsoft Excel™ spreadsheet program was developed to estimate the modal mineral abundance of ultramafic rocks for use in MCP estimation. The calculator is intended for use by the mining industry utilising abundant lithogeochemical data as a cost-effective tool in evaluating their deposit as a supplier of substrate material for industrial mineral carbonation operation. The calculator can be tailored to estimate MCP values based on a site specific mineral assemblage. MCP values generated represent composited sample length intervals along exploration drill holes. Estimation techniques traditionally used by the mining industry for resource estimation were evaluated as methods of geospatially interpolating MCP values. Both inverse distance and ordinary kriging were successful in interpolating MCP values. A capacity of 75 million tonnes of CO₂ within the proposed 28 year surface mine design at Turnagain was calculated. This capacity is significantly lower than the theoretical maximum capacity of 538 million tonnes calculated assuming all MgO within the waste rock is capable of sequestering CO₂ as magnesite (MgCO₃). The research highlights the importance of understanding and quantifying the mineralogy of ultramafic deposits when estimating their potential for mineral carbonation.

description: We show that the shear-induced solidification of dilute charge-stabilized (DLVO) colloids is due to the interplay between the shear-induced formation and breakage of large non-Brownian clusters. While their size is limited by breakage, their number density increases with the shearing-time. Upon flow cessation, the dense packing of clusters interconnects into a rigid state by means of grainy bonds, each involving a large number of primary colloidal bonds. The emerging picture of shear-driven solidification in dilute colloidal suspensions combines the gelation of Brownian systems with the jamming of athermal systems.

description: We report CCD V and I time series photometry of the globular cluster NGC 5024 (M53). The technique of difference image analysis has been used which enables photometric precisions better than 10 mmag for stars brighter than V 18.5mag even in the crowded central regions of the cluster. The high photometric precision has resulted in the discovery of two new RR1 stars and thirteen SX Phe stars. A detailed identification chart is given for all the variable stars in the field of our images of the cluster. Periodicities were calculated for all RR Lyraes and SX Phe stars and a critical comparison is made with previous determinations. Out of four probable SX Phe variables reported by Dekany & Kovacs (2009), the SX Phe nature is confirmed only for V80, V81 is an unlikely case while V82 and V83 remain as dubious cases. Previous misidentifications of three variables are corrected. Astrometric positions with an uncertainty of ~ 0.3 arcsec are provided for all variables. The light curve Fourier decomposition of RR0 and RR1 is discussed, we find a mean metallicity of [Fe/H]=-1.92+-0.06 in the scale of Zinn & West from 19 RR0 stars. The true distance moduli 16.36+-0.05 and 16.28+-0.07 and the corresponding distances 18.7+-0.4 and 18.0+-0.5 kpc are found from the RR0 and RR1 stars respectively. These values are in agreement with the theoretical period-luminosity relations for RR Lyrae stars in the I band and with recent luminosity determinations for the RR Lyrae stars in the LMC. The age of 13.25+-0.50 Gyr (Dotter et al. 2010), for NGC 5024, E(B-V)=0.02 and the above physical parameters of the cluster, as indicated from the RR0 stars, produce a good isochrone fitting to the observed CMD. The PL relation for SX Phe stars in NGC 5024 in the V and I bands is discussed in the light of the 13 newly found SX Phe stars and their pulsation mode is identified in most cases.

description: During major resection of liver carcinoma, liver regeneration (LR) is induced by various clinical and biological factors. Heme oxygenase (HO)-1 has been found as a key inducer of LR in preclinical trial. The clinical evidence for the role of HO-1 in liver dysfunction (LD) including LR is still unknown and has been included in this study. Therefore, plasma HO-1 were monitored during perioperative period in 65 patients with hepatectomy, with 35 training and 30 validation cohorts. LD were evaluated by liver function serum markers and calculation of regeneration indices, respectively. In the training setting, HO-1 levels were remarkably reduced after liver resection (P < 0.001) and gradually recovered within 7 days after surgery. Preoperative HO-1 specifically predicted LD during the first week after surgery (AUC: 0.757; P = 0.01). In patients with LD and complications after surgery, HO-1 levels decreased throughout the perioperative period. In addition, we had also confirmed that low levels of HO-1 (<169 ng/ml) before surgery were associated with an increase in the incidence of postoperative LD and morbidity (P = 0.007, P = 0.045), and decrease of liver regeneration (P = 0.005). And HO-1 was an independent predictor for poor clinical outcome. We had provided the first clinical data verifying that human HO-1 was related to LD. Consequently, HO-1 levels can be used as effective clinical indicators to predict LD and clinical outcome, and can be used as intervention target before liver resection.

description: The bioactive components of Garcinia indica, garcinol (camboginol), and isogarcinol (cambogin), are suitable drug candidates for the treatment of various human diseases. HIV-1-RNase H assay was used to study the RNase H inhibition by garcinol and isogarcinol. Docking of garcinol into the active site of the enzyme was carried out to rationalize the difference in activities between the two compounds. Garcinol showed higher HIV-1-RNase H inhibition than the known inhibitor RDS1759 and retained full potency against the RNase H of a drug-resistant HIV-1 reverse transcriptase form. Isogarcinol was distinctly less active than garcinol, indicating the importance of the enolizable β-diketone moiety of garcinol for anti-RNase H activity. Docking calculations confirmed these findings and suggested this moiety to be involved in the chelation of metal ions of the active site. On the basis of its HIV-1 reverse transcriptase-associated RNase H inhibitory activity, garcinol is worth being further explored concerning its potential as a cost-effective treatment for HIV patients.

description: Clustering is a very popular network structuring technique which mainly addresses the issue of scalability in large scale Wireless Sensor Networks. Additionally, it has been shown to improve the energy efficiency and prolong the life of the network. The suggested protocols mostly base their clustering criteria on some grouping attribute(s) of the nodes. One important attribute that is largely ignored by most of the existing multi-hop clustering protocols is the reliability of the communication links between the nodes. In this paper, we suggest an adaptive and completely distributed multi-hop clustering protocol that incorporates different notions of reliability of the communication links, among other things, into a composite metric and uses it in all phases of the clustering process. The joining criteria for the nodes, which lie at one hop from the elected cluster heads, to a particular cluster not only consider the reliability of their communication link with their cluster head but also other important attributes. The nodes that lie outside the communication range of cluster heads become cluster members transitively through existing cluster members utilizing the end-to-end notion of link reliability, between the nodes and the cluster heads, along with other important attributes. Similarly, inter-cluster communication paths are selected using a set of criteria that includes the end-to-end communication link reliability with the sink node along with other important node and network attributes. We believe that incorporating link reliability in all phases of clustering process results in an efficient multi-hop communication hierarchy that has the potential of bringing down the total communication costs in the network.

description: Many psychologists and others have struggled a lot for many years to establish an effective definition of stress.
 On the basis of some reviews, it can be said that chronic stress is the response to emotional pressure suffered
 for a prolonged period over which an individual perceives he or she has no control. If stress continues for a long time, it can cause damage to an individual's physical and mental health. Psychosocial stress is an important contributor to chronic disease development. Chronic disease causes extended pain and suffering and decreases the quality of life for millions. Stress exposes our body to unhealthy, persistently elevated levels of stress hormones like adrenaline and cortisol. Studies also link stress to changes in the way blood
 clots which increases the risk of heart attack. Stress itself might be a risk factor, or it could be that high levels
 of stress make other risk factors (such as high cholesterol or high blood pressure) worse. For example, you are under stress, your blood pressure goes up, you may overeat, you may exercise less, and you may be more likely to smoke. Many individuals exposed to stressful events do not show signs or symptoms of depression, some individuals exposed to psychological stress are predisposed to major depression Psychosomatic disorders (headache, twitching, gastric ulcer, Cancers, arthritis) can generally develop when a stressful life event occurs. It's not always easy to predict how stress will affect a person s health but it's known that stress does affect a person's health and. therefore, it's important to practice regular stress management techniques.

description: The uncertainty relation and the probability interpretation of quantum mechanics are intrinsically connected, as is evidenced by the evaluation of standard deviations. It is thus natural to ask if one can associate a very small uncertainty product of suitably sampled events with a very small probability. We have shown elsewhere that some examples of the evasion of the uncertainty relation noted in the past are in fact understood in this way. We here numerically illustrate that a very small uncertainty product is realized if one performs a suitable sampling of measured data which occur with a very small probability. It is also shown that our analysis is consistent with the Landau-Pollak type uncertainty relation. It is suggested that the present analysis may help reconcile the contradicting views about the "standard quantum limit" in the detection of gravitational waves.

description: We simulate the nonequilibrium dynamics of two generic many-body quantum impurity models by employing the recently developed iterative influence-functional path integral method [Phys. Rev. B {\bf 82}, 205323 (2010)]. This general approach is presented here in the context of quantum transport in molecular electronic junctions. Models of particular interest include the single impurity Anderson model and the related spinless two-state Anderson dot. In both cases we study the time evolution of the dot occupation and the current characteristics at finite temperature. A comparison to mean-field results is presented, when applicable.

description: Several double perovskite materials of the form A_2BB'O_6 exhibit high ferromagnetic T_c, and significant low field magnetoresistance. They are also a candidate source of spin polarized electrons. The potential usefulness of these materials is, however, frustrated by mislocation of the B and B' ions, which do not organise themselves in the ideal alternating structure. The result is a strong dependence of physical properties on preparative conditions, reducing the magnetization and destroying the half-metallicity. We provide the first results on the impact of spatially correlated antisite disorder, as observed experimentally, on the ferromagnetic double perovskites. The antisite domains suppress magnetism and half-metallicity, as expected, but lead to a dramatic enhancement of the low field magnetoresistance.

The ontogeny of sodium balance of rainbow trout (Oncorhynchus mykiss) and pink salmon (Oncorhynchus gorbuscha) during post-embryonic development in freshwater
Creators: name: Gallagher, Emily Jean
Publisher: name: University of British Columbia
Year: 2014

description: This thesis contributes to our general knowledge of ionoregulatory function in developing fish by characterizing the functional ontogeny of sodium (Na⁺) balance in salmonids reared in freshwater during early development. Chapter 2 investigated the plasticity of Na⁺ balance and transport capacity during a critical developmental transition from cutaneous-dominated to gill-dominated ionoregulation in the model teleost fish, the rainbow trout. Fish experienced very high resting unidirectional Na⁺ uptake rates early in development which were reduced to values typical of adults following yolk absorption. Maximal uptake rate (Jmax) for Na⁺ was high during early development and decreased following yolk absorption while uptake affinity decreased (Km increased) following hatch and increased following yolk absorption. It appeared that early in development, high Na⁺ uptake rates across cutaneous ionocytes were driven by high maximal uptake rate, while the gill ionocytes that dominate ionoregulation post-yolk absorption had an increased affinity for Na⁺. Following hatch, when ionoregulation occurs predominantly across cutaneous ionocytes, larval fish exhibited little ionoregulatory plasticity in their Na⁺ uptake rates and Na⁺ uptake kinetics. As ionoregulation shifts to the gill, developing fish exhibited increased uptake affinity for Na⁺ in low-[Na⁺] environments as observed in adult fish; however, maximal uptake rate for Na⁺ did not increase in low-[Na⁺] environments as seen in adult fish, suggesting that the capacity to overcome Na⁺-poor environments may be limited and still developing at this stage. Chapter 3 contributed to our understanding of Na⁺ transport during early salmonid development and explored Na+ transport characteristics employed by the early-migrating anadromous salmonid, the pink salmon. It was clear that heightened and increasing whole-body [Na⁺] during yolk absorption in freshwater was not a unique characteristic of developing pink salmon associated with preparation for early ocean entry. This trait was shared by the non-anadromous rainbow trout. Interestingly, the mechanism by which pink salmon and rainbow trout achieved high whole-body [Na⁺] during early development did not appear to be the same. Rainbow trout experienced increasing Na⁺ uptake rates during development while pink salmon did not alter Na⁺ uptake rates during development, suggesting that pink salmon regulated whole-body [Na⁺] via modulation of Na⁺ efflux rates

description: We study the counting statistics of ultracold bosonic atoms that are released from an optical lattice. We show that the counting probability distribution of the atoms collected at a detector located far away from the optical lattice can be used as a method to infer the properties of the initially trapped states. We consider initial superfluid and insulating states with different occupation patterns. We analyze how the correlations between the initially trapped modes that develop during the expansion in the gravitational field are reflected in the counting distribution. We find that for detectors that are large compared to the size of the expanded wave function, the long-range correlations of the initial states can be distinguished by observing the counting statistics. We consider counting at one detector, as well as the joint probability distribution of counting particles at two detectors. We show that using detectors that are small compared to the size of the expanded wave function, insulating states with different occupation patterns, as well as supersolid states with different density distributions can be distinguished.

Electron transport across a quantum wire in the presence of electron leakage to a substrate

description: We investigate electron transport through a mono-atomic wire which is tunnel coupled to two electrodes and also to the underlying substrate. The setup is modeled by a tight-binding Hamiltonian and can be realized with a scanning tunnel microscope (STM). The transmission of the wire is obtained from the corresponding Green's function. If the wire is scanned by the contacting STM tip, the conductance as a function of the tip position exhibits oscillations which may change significantly upon increasing the number of wire atoms. Our numerical studies reveal that the conductance depends strongly on whether or not the substrate electrons are localized. As a further ubiquitous feature, we observe the formation of charge oscillations.

An experimental apparatus for the laser cooling of lithium and rubidium
Creators: name: Bowden, William James
Publisher: name: University of British Columbia
Year: 2014

description: We demonstrate a two species effusive source and Zeeman slower for lithium 6 and rubidium 85. The fluxes produced by this slower allow for magneto-optical trap loading rates in excess of 10⁸ atoms per second for both species. A detailed model is developed to predict the emission properties of the effusive source along with the flux of cold atoms produced by the slower. Novel to this design is the mating of Zeeman slower magnetic field to the field produced by trapping coils which increases the effective length over which atoms are slowed. This allows for a smaller, more compact slower, without a sacrifice in performance. Details relating to the design and performance of the vacuum system and magnetic field producing coils are also covered. The apparatus can be easily adapted to operate with different atomic species making it well suited for ultracold atomic physics experiments studying mixtures or as starting point for the creation of hetero-nuclear molecules.

description: We propose an evolutionary path for prestellar cores on the radius-mass diagram, which is analogous to stellar evolutionary paths on the Hertzsprung-Russell Diagram. Using James Clerk Maxwell Telescope (JCMT) observations of L1688 in the Ophiuchus star-forming complex, we analyse the HCO+ (J=4\rightarrow3) spectral line profiles of prestellar cores. We find that of the 58 cores observed, 14 show signs of infall in the form of a blue-asymmetric double-peaked line profile. These 14 cores all lie beyond the Jeans mass line for the region on a radius-mass plot. Furthermore another 10 cores showing tentative signs of infall, in their spectral line profile shapes, appear on or just over the Jeans mass line. We therefore propose the manner in which a prestellar core evolves across this diagram. We hypothesise that a core is formed in the low-mass, low-radius region of the plot. It then accretes quasistatically, increasing in both mass and radius. When it crosses the limit of gravitational instability it begins to collapse, decreasing in radius, towards the region of the diagram where protostellar cores are seen.
