description: Obesity prevalence rates continue to rise in North America, which suggests that creating successful intervention should be forefront on the research agenda. It has been proposed that motivational interviewing (MI) may be an effective means by which to improve efficacy of current behavioural weight loss treatment. Given that MI addresses ambivalence and enhances motivation towards change it may enable individuals to commit and persist with the necessary health-related behavioural changes required for successful weight loss. The aim of this study was to assess whether incorporating MI into a behavioural weight loss program (BWLP) resulted in improvement on weight loss outcomes and related secondary outcomes (i.e., physical activity, dietary habits, blood pressure, and disordered eating) relative to an attention control group. One hundred and thirty-five (105 females, 30 males) overweight and obese participants (mean BMI = 33.58 kg/m2) were randomized to receive a 12-week BWLP plus two MI sessions, or the same BWLP pus two attention control sessions (93% retention rate). The MI or control session occurred at the beginning of the BWLP and just prior to completion of the BWLP program. Participants were assessed at baseline, end of the BWLP, I-month post BWLP, and 6-months post BWLP. Results showed that participants in both groups significantly decreased their weight and improved on indicators of physical activity, diet, and disordered eating (p < .05). However, changes in weight and related outcomes did not differ between the two study groups. Future research is needed to carefully examine the construct of motivation in weight loss studies and determine methodological factors that are most associated with improved MI outcomes.
Technological Change, Sunk Costs, and Competition
Creators: name: Stiglitz, Joseph E.

Subjects: Economics

description: The purpose of this article is to address the validity or generality of the premise that potential competition suffices to ensure economic efficiency. It is a paper as much about the models used to justify beliefs about the design of economic policy as it is about what those policies should be. Markets in which technological change is important are never perfectly competitive, and in imperfectly competitive markets, vertical restraints may also serve to alter the degree of competition. There are a number of reasons why the conventional theory of competition does not describe well the industrial sectors in which technological change is important, among them that technological change inherently entails an element of increasing returns and that expenditures on research and development are, for the most part, sunk costs. While traditional economic analysis argued that in the presence of increasing returns there was a trade-off between having many firms with less monopoly power but a loss in productive efficiency or a few firms with more power and more efficiency, the contestability doctrine claims there is no trade-off.

description: Mesenchymal stem cells (MSCs) were isolated from porcine synovial fluid (SF), and clonal populations derived through limiting dilution. Eighteen clones from three pigs (6 per pig) were then analyzed for their proliferative and differentiation characteristics. All 18 clones were able to undergo at least 25 population doublings, suggesting a high self-renewal capability. Their differentiation properties were assessed using histological stains and RT-PCR. Less than 50% of clones were capable of osteogenic differentiation, while greater than 75% were bipotent chondro-adipo progenitors; a phenotype never reported in other tissue types. In addition, all but one clone differentiated into chondrocytes, indicating an enhanced potential for cartilage regeneration. Despite using clonal populations, a great deal of variation was present between clones showing distinct differentiation potentials. The presented study suggests that clonal analysis is an effective method of identifying subpopulations in porcine SF, and that SF-derived MSCs may be an ideal tissue source for regenerating cartilage.

The effect of acidic extracellular ph on direct anticryptococcal activities of nk cells
Creators: name: Islam, Anowara
Publisher: name: University of Calgary
Year: 2012

description: Bibliography: p. 92-111
description: Cryptococcus produces a solid tumor-like mass that is called a cryptococcoma. Analogous to tumors, the cryptococcoma microenvironment can be very acidic, which presents challenges to host defense. Analogous to tumor cells, Cryptococcus can be killed by NK cells. As acidic pH inhibits NK cell anti-tumor activities, we examined if there was a similar reduction in NK cell anticryptococcal activities. Surprisingly, we found that NK cells have preserved or even enhanced killing of Cryptococcus in acidic compared to physiological pH. Acidic pH did not increase processes that might increase killing including the effector to target ratio, binding of NK cells to Cryptococcus, or the active perforin content in NK cells. By contrast, acidic pH enhanced ERKl/2 phosphorylation and perforin degranulation, which are essential for cryptococcal killing. Moreover, increased killing occurred during more rapid replication of the organisms. These results suggest that NK cells have amplified signaling, degranulation, and greater capacity to kill microbes at low pH and when the organisms replicate quickly.
The New Development Economics

description: The theory of rural organization based on rational peasants in environments where information is imperfect and costly provides a simple explanation for a wide variety of phenomena in LDCs. It provides insights into both why sharecropping is so widespread and why it takes on the particular forms that it does; it provides an explanation of the interlinkage of credit and land markets, and of cost sharing. The paper argues that this theory provides a better explanation of these phenomena than do the competing theories. This theory can be viewed as an important application of a more general paradigm, the "Imperfect Information Paradigm," which has been useful in explaining economic phenomena under a wide variety of settings: under competition, oligopoly, and monopoly; in labor markets, capital markets, in insurance markets, and product markets; and in developed and less developed countries.

description: Three processes coincided in the first years of the 21st Century to create a water crisis in parts of the western United States. Rapid population growth, decline in construction of new water projects, and deep drought shocked water officials who thought their supplies were secure for at least a few years, and unexpected and drastic curtailments in water use were required. These experiences have been especially acute in Colorado, where parts of the state are experiencing the worst drought water shortages since settlement. The first part of the paper outlines the causes and nature of the drought water shortages and the second identifies policy needs. It is argued that if water security for regions can be achieved, building new storage should be easier because more public support will be available. In addition to more and "smarter" storage, the state needs more workable water markets. The idea of balance among regions will also help with that goal because regions can agree externally and internally on water transfers, thus facilitating water markets. Colorado has enough water for its future if it acts wisely. However, new institutional mechanisms to promote the interests of the state's regions can work to improve water availability within and among regions and look after environmental values.
Petrology of ultramafic xenoliths, Rayfield River and Big Tomothy mountain areas, British Columbia

Publisher: name: University of Calgary

description: Bibliography: p. 127-131
description: Ultramafic xenoliths from Rayfield River and Big Timothy Mountain, British Columbia are interpreted to represent the underlying upper mantle. Both localities are Tertiary volcanic cones consisting of alkali basalt flows. The xenoliths are spine! lherzolites and less commonly harzburgites and pyroxenites. Mineral assemblages include olivine, clinopyroxene, 01thopyroxene, and spinel. Microprobe analysis of the individual grains determined that all phases were generally compositionally homogeneous. A number of geothermometers have been assessed to determine the thermal conditions under which the peridotite samples equilibrated. These include two­pyroxene thermometry, spinel-orthopyroxene, and spinel-olivine equilibration. Temperatures calculated using the Brey and Kohler calibration of two-pyroxene thermometry are interpreted to represent the temperature of equilibration. The Rayfield River xenoliths, average two-pyroxene temperatures of 912 ± 42° C. Orthopyroxene­spinel and olivine-spine! results are 889 ± 60° C and 825 ± 88° C, respectively. Big Timothy Mountain xenoliths have an average two-pyroxene temperature of 959 ± 62° C. Orthopyroxene-spinel and olivine-spine! temperatures are 844 ± 63° C and 896 ± 232°C, respectively. The pressure range in which the peridotite equilibrated within the upper mantle must be estimated based on the stability of the minerals. Isochemical phase diagrams (pseudosections) constrain the P-T field in which spine! is stable and is the sole aluminous phase (i.e. garnet and plagioclase remain unstable). With the use of these diagrams it can be concluded that this assemblage equilibrated in pressures ranging from approximately 9.6 to 14 kbar and at depths of approximately 33 to 48 km. The effect of pressure on the temperature calculations is negligible; they change only ~2°C/kbar. Overall, there is very good agreement between the isochemical phase diagrams, temperatures, and the observed mineral assemblage. Oxygen fugacity (??logfo2) calculations were done on both of the peridotite suites to constrain the oxidation state of the upper mantle. The results are typical of a moderately reduced and depleted upper mantle, having an average of~ l.3 log units below FMQ (fayalite-magnetite-quartz). In addition, the peridotites represent residua from the partial melting of the upper mantle. Compositionally, the peridotites from Big Timothy Mountain are fairly fertile with a MgO weight percent ranging from ~35-43% and Ab03 around 3%; these correspond to 8- 10% partial melting of primitive mantle. This relatively fertile lherzolite represents upper mantle underlying the Canadian Cordillera. A result of this study, determining the thermal conditions of the upper mantle, is to build a geothermal gradient for the southern Intermontane belt by combining thermal data determined for the area and the calculated pressure/temperature conditions.

description: This article examines the theory of involuntary unemployment and implicit contracts. Furthermore, the article is concerned with identifying the circumstances under which implicit contracts will give rise to unemployment even though involuntary unemployment has been often attributed to wage rigidities generated by implicit contracts by themselves. Moreover, a simple, general equilibrium model and the three sources of restrictions on the set of feasible contracts: (1) information; (2) enforcement; and (3) complexity. Finally, it is concluded that implicit contracts can then provide an explanation of unemployment.
Toward the fabrication and testing of all-polymer micronozzle
Creators: name: Abdollahzadeh, Delaram
Publisher: name: University of British Columbia
Year: 2011

description: A disposable all-polymer micronozzle was designed and fabricated by merging the two different technologies of microfluidics and microneedles together. Polymer micronozzles (polyimide and SU-8) were fabricated using different steps of spin casting and one step of photolithography. Microfluidic devices consisting of one input channel and one output channel each with a 500µm diameter, and connected with a channel 100µm in width, were fabricated using the PDMS polydimethylsiloxane (PDMS) casting. To achieve a thin PDMS membrane, spin casting of PDMS over the mold is required. The fabricated thin PDMS microfluidic layers were bonded to polymer nozzles using oxygen plasma treatment and precisely aligning the two layers together. The resulting polymer nozzles were connected to the pressure system of a custom made inkjet printer, by the means of a plastic holder device. The holder device was designed in SolidWorks and printed using a 3D printer. Finally a solenoid actuator was attached to the setup. Different solenoid plunger tips were designed to maximize the deformation of the PDMS membrane which is used to attempt liquid ejection and printing. First the internal pressure was tuned. The effect of frequency, duty cycle and input voltage of the solenoids input pulse on the created pending droplet’s volume was characterized experimentally. The maximum displaced volume was found with actuation for a 12V input pulse with 10% duty cycle. For a 50µm nozzle diameter this volume is 4.78×10⁻¹¹ L and for a 200µm it is 3.83×10⁻¹ºL. Reducing the surface tension of water using surfactant resulted in flow of ink onto the hydrophilic plasma-treated SU-8 surface, and total surface wetting.

description: Buzz marketing, a dynamic form of word-of-mouth promotion, has emerged as a pivotal strategy in the digital era, leveraging social interactions, influencer endorsements, and viral content to shape consumer perceptions and drive brand engagement. As traditional advertising faces skepticism, businesses increasingly rely on buzz marketing to create organic discussions and excitement. This study explores the effectiveness of buzz marketing in enhancing brand awareness, trust, and purchase intent by analyzing psychological triggers such as exclusivity, curiosity, and social proof. While buzz marketing fosters consumer engagement, it also presents challenges, including misinformation, over-hyped expectations, and ethical concerns. Through case studies of brands like Zomato, Vivo, and Swiggy, this research highlights successful buzz marketing strategies and evaluates their long-term impact on brand loyalty and credibility. The findings emphasize the need for ethical execution and strategic alignment between marketing efforts and consumer expectations to ensure sustained success.

The Consequences of the Dependence of Quality on Price
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University
Year: 1987
Subjects: Economics

description: This paper is concerned with situations where firms not only recognize the dependence of quality on price (of productivity on wages, of default probability on the interest rate charged), but also attempt to use what control they have over price (wages, interest rates) to increase their profits. The recognition of this possibility has important implications for economic theory, which have recently been explored in a large number of papers in several disparate fields. The objective of this paper is to survey these papers and to draw out the central themes of this literature. This paper is divided into four parts, In Part I, we discuss the most important implications of the dependence of quality on price for competitive equilibrium theory--the repeal of the law of supply and demand (Part I.1), the repeal of the law of the single price (Part I.2), the existence of discriminatory equilibria (Part I.3), the comparative static consequences (Part I.4), and the inefficiency of market equilibria (Part I.5). Part II discusses alternative explanations for the dependence of quality on price in labor, capital, and product markets.

description: Abstract 
This review explores the effects of petroleum product distribution on soil quality and ecosystems in Nigeria. This paper examines the adverse impacts of distributing petroleum products on the environment, with a specific emphasis on soil ecosystems. The harmful hydrocarbons in the soil have negative consequences for soil nutrient levels, water-holding capacity, and microbial function, with potential impacts on agriculture, biodiversity, and human well-being. Previous studies show that soil contamination in Nigeria due to petroleum product distribution presents complex challenges, such as insufficient monitoring and enforcement, limited financial resources for clean-up, and a fragmented regulatory framework. Thus, this review emphasizes the importance of improving regulatory frameworks, monitoring and enforcement mechanisms, and public awareness and education initiatives to reduce the negative impacts of petroleum product distribution on soil. Efficient measures are required to prevent and restore soil contamination, including spill response protocols, infrastructure maintenance, and cooperative relationships among governmental entities, industries, and local communities. Recommendations were drawn on the significance of pollution control, sustainable management practices, and community engagement in preserving environmental quality and supporting ecosystems for the benefit of nature and communities.

description: The new generation of electricity grid, the Smart Grid, has the promise to bring further efficiency, security and reliability to the power system. With the integration of commu­nication network, smart meters and other intelligent technologies, power companies can develop demand response programs that allow their customers to participate in the power market. Smart meters usually collect electricity consumption data at hourly basis. The data can not reveal the true inter-hour electricity-use dynamics, which is important in demand response programs. The first part of this thesis studies two different metering approaches, i.e. interval metering & threshold metering, with the hope to enlighten the metering con­figuration for future smart meters. The second part of this thesis directly compares the demand response potential contributed by a pool of cooling devices with two different con­trol mechanisms, e.g. direct compressor control & thermostat set-point control. Finally, this thesis also proposes a new damping technique used to reduce the demand oscillation created in demand response.
Bottom-trapped currents as statistical equilibrium states above topographic anomalies

description: Oceanic geostrophic turbulence is mostly forced at the surface, yet strong bottom-trapped flows are commonly observed along topographic anomalies. Here we consider the case of a freely evolving, initially surface-intensified velocity field above a topographic bump, and show that the self-organization into a bottom-trapped current can result from its turbulent dynamics. Using equilibrium statistical mechanics, we explain this phenomenon as the most probable outcome of turbulent stirring. We compute explicitly a class of solutions characterized by a linear relation between potential vorticity and streamfunction, and predict when the bottom intensification is expected. Using direct numerical simulations, we provide an illustration of this phenomenon that agrees qualitatively with theory, although the ergodicity hypothesis is not strictly fulfilled.
Improved maximum power point tracking for a photovoltaic array without a pi regulator using a novel constant voltage tracking algorithm

description: Bibliography: p. 86-91
description: Human induced deleterious environmental impacts have been a serious concern for many decades. Therefore, the use of "green energy" sources (solar, wind, hydro etc.) is being strongly supported and is growing at an increasing rate. Photovoltaic power generation is becoming quite popular and less expensive with the advancements in manufacturing technology. Photovoltaic power generation is being encouraged for both stand-alone and grid-connected applications. This thesis presents the modeling and simulation of two very simple, economical and efficient maximum power point trackers (MPPTs) used for a polycrystalline PV array charging a battery with a buck converter. First, a very simple MPPT controller with no proportional-integral (PI) regulator is proposed. This has the main advantage of having no tuning parameters. Second, a new way to determine the reference voltage for the Constant Voltage Tracking (CVT) controller is presented. The new method, Difference CVT, considerably increases tracking efficiency of the CVT algorithm.

description: Active galactic nuclei (AGN) emit radiation over a wide range of wavelengths, with a peak of emission in the far-UV region of the electromagnetic spectrum, a spectral region that is historically difficult to observe. Using optical, GALEX UV and XMM-Newton data we derive the spectral energy distribution (SED) from the optical/UV to X-ray regime of a sizeable sample of AGN. The principal motivation is to investigate the relationship between the optical/UV emission and the X-ray emission and provide bolometric corrections to the hard X-ray (2-10 keV) energy range, kbol, the latter being a fundamental parameter in current physical cosmology. We construct and study the X-ray to optical SED of a sample of 195 X-ray selected Type 1 AGN belonging to the XMM-Newton bright serendipitous survey (XBS). The optical-UV luminosity was computed using data from the Sloan Digital Sky Survey (SDSS), from our own dedicated optical spectroscopy and the satellite Galaxy Evolution Explorer (GALEX), while the X-ray luminosity was computed using XMM-Newton data. Because it covers a wide range of redshift (0.03 < z < 2.2), X-ray luminosities (41.8 < logL[2-10]keV < 45.5 erg/s) and because it is composed of "bright objects", this sample is ideal for this kind of investigation. We find a correlation between kbol and the hard X-ray photon index Γ(2-10keV) and a tight correlation between the optical-to-X-ray spectral index αox and kbol, so we conclude that both Γ(2-10keV) and αox can be used as a proxy for kbol.

Competition and the Number of Firms in a Market: Are Duopolies More Competitive than Atomistic Markets?
Creators: name: Stiglitz, Joseph E.
Publisher: name: Columbia University
Year: 1987
Subjects: Economics

description: This paper uses a variant of the standard search model to examine market equilibrium and the consequences of an increase in the number of firms. If marginal search costs increase with the number of searches, then the demand curve facing any firm will be kinked, with the elasticity of demand with respect to price decreases being less than with respect to price increases; prices may not change in response to changes in marginal costs. As the number of firms increases, the maximum price that is consistent with equilibrium increases to the monopoly price, but the minimum price decreases. On the other hand, if marginal search costs decrease with the number of searches, equilibrium, if it exists, is characterized by a price distribution.

description: Bibliography: p. 160-171
description: A few pages are in colour.
description: This research thesis aims to develop multi-band/multi-standard, reconfigurable transmitter architecture capable of operating on number of different wireless standards at different carriers. Such transmitter is intended to be used in software defined radio terminals, which are most suitable for upcoming wireless network applications. With the increase in multi-media applications and multi-functionality, the efforts are to obtain high data rate and highly spectrum efficient communication schemes with satisfactory quality of service to the subscribers. Moreover, the upcoming standards should have backward compatibility with existing network standards in order to provide smooth network migration. Therefore, reconfigurable multi-band/multi-standard software defined radio systems must be adopted. In addition, the high efficiency linear region of these transmitter systems should also be increased in order to efficiently handle advanced modulation schemes with high peak to average power ratios while maintaining the high linearity requirements. For the proof of concept, this research is focused on the development of dual-band/dual­standard reconfigurable transmitter architecture that utilizes dual-band Doherty power amplifier for high efficiency operation in the back-off region with Hybrid-RF-digital predistortion based linearization scheme implemented on a reconfigurable Field programmable gate array (FPGA) platform. Since, the linearization scheme is implemented in FPGA, it gives multi-standard capability, whereas dual-band Doherty provides the dual-band capability to RF front-end of the transmitter.

Year: 1987
Subjects: Economics

description: Formal developments of the Keynes's General Theory, while attempting to achieve a new classical synthesis of the realities of observed macroeconomic fluctuation and unemployment with classical microeconomics, have come to be surprisingly closely tied to the old classical models. Keynes's insights have been reduced largely to an assumption of nominal price rigidities. In fact, Keynes's original qualitative approach contained a much richer description of economic reality. This paper describes how fully rational microeconomic models incorporating imperfect information and incomplete markets, very much in the Keynesian tradition, imply macroeconomic behavior that encompasses most of the qualitative insights of the General Theory.

The low energy constants appearing in $\mathcal{O}(p^2)$ chiral Lagrangian are determined by fitting lattice simulations on $S$-wave scattering lengths. $D_{s0}^{*}(2317)$ is obtained as a bound state in $(S,I)=(1,0)$ $DK$ channel. Possible bound states or resonance states in other channels are investigated as well. The quark mass dependence of the mass and binding energy of $D_{s0}^{*}(2317)$ is also investigated, which indicates predominately $DK$ molecular nature.

description: Afshordi, Aslanbeigi and Sorkin have recently proposed a construction of a distinguished "S-J state" for scalar field theory in (bounded regions of) general curved spacetimes. We establish rigorously that the proposal is well-defined on globally hyperbolic spacetimes or spacetime regions that can be embedded as relatively compact subsets of other globally hyperbolic spacetimes, and also show that, whenever the proposal is well-defined, it yields a pure quasifree state. However, by explicitly considering portions of ultrastatic spacetimes, we show that the S-J state is not in general a Hadamard state. In the specific case where the Cauchy surface is a round 3-sphere, we prove that the representation induced by the S-J state is generally not unitarily equivalent to that of a Hadamard state, and indeed that the representations induced by S-J states on nested regions of the ultrastatic spacetime also fail to be unitarily equivalent in general. The implications of these results are discussed.

description: In this thesis, I analyse how the literary works of Elisabeth Reichart,
      Charlotte Roche and Elfriede Jelinek challenge normativity both in their
      engagement with gender and sexuality and with aesthetic choices. The
      comparative analysis of texts published over a period of twenty years
      (Fotze, 1993; Feuchtgebiete, 2008; and SCHATTEN (Eurydike sagt), 2013)
      provides insights into the socio-political and cultural dynamics at the
      different times of publication. Furthermore, such analysis reveals the
      continuing relevance of feminist authorial voices to the present day. At
      the same time, through the engagement with authors of different
      generational and professional backgrounds who might have diverging and in
      some regards contrasting perspectives on gender and sexuality, my thesis
      intends to challenge a stable, normative understanding of feminism and
      feminist writing itself.

      By combining performativity and performance theory not just with textual
      analysis but also with reader-response criticism, I make use of an
      innovative theoretical framework which allows me to outline how literature
      can expose and destabilise harmful gender norms. For this matter, I
      interrogate Reichart’s, Roche’s and Jelinek’s highly controversial
      engagement with issues around intimate hygiene, sexuality, sexually
      explicit discourse and rigid gender structures. Simultaneously, I show how
      the texts’ provocative and unsettling content is mirrored also in the
      aesthetic strategies they employ. These include discontinuous storylines,
      humour and parody, and the blurring between fantasy and reality. I further
      explore the potential that I see not only in literary texts but also in
      the authors’ own public performances to intervene in norms on multiple
      levels. The aim of my thesis is to make a case for an anti-normative
      analysis of literature, which makes the ways in which a text confronts us
      with ambiguities, insecurities and uncomfortable topics productive. In
      this sense, I show how literature can function as a form of intervention
      that provides a reflective space for readers to question norms in their
      own lives and to take the initiative to change these norms.

description: Unstable four-boson states having an approximate dimer-atom-atom structure are studied using momentum-space integral equations for the four-particle transition operators. For a given Efimov trimer the universal properties of the lowest associated tetramer are determined. The impact of this tetramer on the atom-trimer and dimer-dimer collisions is analyzed. The reliability of the three-body dimer-atom-atom model is studied.

Src family kinases are required for nk cell microbicidal activity to cryptococcus neoformans

description: NK cells are well known for their ability to recognize and kill tumor and virally infected cells. Numerous studies have now demonstrated that NK cells also possess the ability to directly recognize and kill bacteria, parasites and fungi such as the pathogenic fungus Cryptococcus neoformans. However, the precise signalling pathways governing NK cell microbicidal activity are still unknown. Previously, it was reported that activation of a conserved PI3K -ERK l /2 pathway is necessary for NK cell anticryptococcal activity. Using YT (NK-like cell line) and primary human NK cells, we sought to identify the upstream signalling elements that lead to the activation of this pathway. We demonstrate that Src family kinases, in particular Fyn, were activated in response to C. neoformans. Furthermore, pharmacologic inhibition with a Src family kinase inhibitor (dasatinib) was found to block C. neoformans induced activation of PI3K and ERKI/2 and abrogate cryptococcal killing. At the same time, dasatinib was observed to disrupt the polarization of perforin-containing granules towards the NK cell-cryptococcal synapse but had no effect on conjugate fom1ation between NK cells and C. neoformans. Finally, double (but not single) siRNA knockdown of two specific Src family kinases, Fyn and Lyn, was found to completely block cryptococcal killing. \Ve also demonstrate that neither Syk nor ZAP-70 were activated in response to C. neoformans. Moreover, anticryptococcal activity was found to be insensitive to both pham1acologic inhibition with a Syk inhibitor (Syk inhibitor II) and siRNA knockdown of ZAP-70. Together these data demonstrate a mechanism whereby the Src family kinases, Fyn and Lyn, redundantly mediate anticryptococcal activity through the IT AM (Syk/ZAP-70) independent activation of PBK-ERKI/2, which in turn facilitates killing by inducing the polarization of perforin-containing granules to the NK cell-cryptococcal synapse.
BCS-BEC crossover in spin-orbit coupled two-dimensional Fermi gases

description: The recent experimental realization of spin-orbit coupling for ultra-cold atoms has generated much interest in the physics of spin-orbit coupled degenerate Fermi gases. Although recently the BCS-BEC crossover in three-dimensional (3D) spin-orbit coupled Fermi gases has been intensively studied, the corresponding two-dimensional (2D) crossover physics has remained unexplored. In this paper, we investigate, both numerically and analytically, the BCS-BEC crossover physics in 2D degenerate Fermi gases in the presence of a Rashba type of spin-orbit coupling. We derive the mean field gap and atom number equations suitable for the 2D spin-orbit coupled Fermi gases and solve them numerically and self-consistently, from which the dependence of the ground state properties (chemical potential, superfluid pairing gap, ground state energy per atom) on the system parameters (e.g., binding energy, spin-orbit coupling strength) is obtained. Furthermore, we derive analytic expressions for these ground state quantities, which agree well with our numerical results within a broad parameter region. Such analytic expressions also agree qualitatively with previous numerical results for the 3D spin-orbit coupled Fermi gases, where analytic results are lacked. We show that with an increasing SOC strength, the chemical potential is shifted by a constant determined by the SOC strength. The superfluid pairing gap is enhanced significantly in the BCS limit for strong SOC, but only increases slightly in the BEC limit.

description: The question of how the funds required for the capital accumulation associated with industrialization are to be raised has a long history. Since the industrial sector is relatively small in the early stages of industrialization, there has been a presumption that funds must primarily come from the agricultural sector. A simple model of a closed socialist economy in which the instruments at the disposal of the government are the terms of trade and the industrial wage, sheds some light on these questions, particularly in the context of the Soviet industrialization debate. In an economy facing binding constraints in external trade, a lowering of the price of the rural good, which reduces the supply of rural surplus available to the urban sector, must be accompanied by a lowering of the urban wage to reduce the demand for the rural good, and hence to balance the supply and demand of the rural good. A virtue of developing a general theoretical framework is that it enables one to isolate those features of the economy which are critical for the issues at hand.
