description: Slips, trips and falls are one of the leading causes of injury and result in billions of dollars in medical and insurance costs annually. Current determination of slip potential does not always accurately predict whether an individual will slip or not. To better predict slip incidents, it may be possible to evaluate only one component, horizontal force, of the current friction calculation. The purpose of this dissertation was to determine if horizontal force generation would serve as a more accurate predictor of slip probability for movements associated with a high-risk of slipping; a 90° change in direction. It was discovered that if at least 50N of horizontal force was generated by 10.08ms following heel-strike, the corresponding slip distance was less than 100mm. By using the horizontal force generation associated with early heel-strike, the probability of correctly classifying slip and non-slip situations was greater compared to the currently utilized friction method.

New material examined. EAST MALAYSIA; Sabah State • 2♂; Maliau Basin Conservation Area, at Maliau Basin Studies Centre accommodation (Keruing); N4.73588 E116.97442; 17 November 2024, evening; attracted to light; coll. M.K. Tan; SBH.24.139, 147 (ZRC).
Remarks. Our specimens from Maliau Basin (Fig. 9) show similarities with Ps. (Ps.) melanonota (Stål, 1876) from Sumatra and Malay Peninsula, Ps. (Ps.) imitativa Gorochov, 2024 from Mindanao (Philippines) and Ps. (Ps.) simulator Gorochov, 2024 from Sabah (Borneo). The dark colouration and patterns on the pronotum most resemble Ps. (Ps.) melanonota, but our specimens differ from all three species by the dorsum of the head completely red, instead of having merely red patterns as in Ps. (Ps.) imitativa or limited to only the upper rostral tubercle. Each tegmen has a conspicuous reddish stripe along the proximal branch of the Sc vein, resembling those in Ps. (Ps.) imitativa rather than Ps. (Ps.) melanonota. The left stridulatory area of our specimens is mostly similar to that of Ps. (Ps.) simulator in the shape and relative size of the mirror, but is most similar to Ps. (Ps.) imitativa in the shape of the stridulatory file. The male cercus resembles Ps. (Ps.) imitativa and Ps. (Ps.) simulator more than Ps. (Ps.) melanonota by the shorter relative distance between the two apical and preapical teeth. The male subgenital plate resembles Ps. (Ps.) melanonota and Ps. (Ps.) imitativa by the apical notch deeper than that in Ps. (Ps.) simulator. These suggest that the three species and our specimens may possibly represent a single species or part of a species complex. Here, we tentatively identify our specimens as Ps. (Ps.) imitativa owing to the overall similarities in the stridulatory file on the left tegmen, cercus, and male subgenital plate.

description: This thesis explores how gay men navigate and interpret varying social contexts, and adapt their performances of “gay” in response. The findings are drawn from 27 qualitative interviews with gay men, sampled primarily from Calgary, Canada. The data suggest that stereotypical, gender-inverted performances of gay are one of many variable performances and, taken together, these performances reflect a gay hierarchy within the broader masculine hegemony. This thesis further suggests that the stereotypical gay performance has implications for gay male performativity, characterizing the set of behaviours that gay men manipulate so as to signify, or fail to signify “gay” to others. Gay men’s highly attuned capacities for performance and gender self-reflexivity are also discussed, and the concept of “social categorization strategies” is introduced to describe the assessment processes that inform gay men’s performance decisions. Ultimately, a case is made to consider “gay” in performative terms, distinct from a homosexual orientation.

description: In this paper a Time Division Multiple Access (TDMA) based Random Access (RA) channel with Successive Interference Cancellation (SIC) is considered for a finite user population and reliable retransmission mechanism on the basis of Contention Resolution Diversity Slotted ALOHA (CRDSA). A general mathematical model based on Markov Chains is derived which makes it possible to predict the stability regions of SIC-RA channels, the expected delays in equilibrium and the selection of parameters for a stable channel configuration. Furthermore the model enables the estimation of the average time before reaching instability. The presented model is verified against simulations and numerical results are provided for comparison of the stability of CRDSA versus the stability of traditional Slotted ALOHA (SA). The presented results show that CRDSA has not only a high gain over SA in terms of throughput but also in its stability.

description: This thesis presents the mathematical and numerical methods necessary to regularise and evolve Brill Gravitational Waves in spherical polar coordinates. A Cauchy ADM formulation is used for the time evolution. We find strong evidence that all IVP formulations of pure vacuum Brill gravitational waves collapse to form singularities/black holes, and we do not observe critical black hole mass scaling phenomena in the IVP parameter phase space that has been characterised in non-vacuum systems. A theoretical framework to prove this result analytically is presented. We discuss the meaning of Brill metric variables, the topology of trapped surfaces for various scenarios, and verify other results in the field related to critical values of initial value parameters and black hole formation approaching spatial infinity. The instability of Minkowski (flat) space under Brill wave and more general perturbations is demonstrated. The main numerical tools employed to achieve a stable evolution code are (1) derivation of appropriate regularity conditions on the lapse function a and metric function q, (2) the move to a 4th order correct discretisation scheme with appropriate boundary conditions, (3) the use of exponential metric terms, (4) an understanding of the right mix of free versus constrained evolution and (5) the development of appropriate numerical techniques for discretisation and differencing to reduce numerical error, along with a characterisation of condition numbers.
The Development Of Appropriate Noise Scales For The Prediction Of Community Response To Urban Light Rail Systems
Creators: name: Birden, Daryl Weston
Publisher: name: London South Bank University
Year: 1990

description: Higher than predicted levels of noise annoyance were reported by people living close to the Docklands Light Railway (DLR) following its opening in 1987. Analysis of the noise produced showed that in places the spectrum was dominated by high sound pressure levels in the 63 Hz octave band. The basis of the annoyance criteria applied by the DLR has been examined and the application of these criteria to the noise problems of New Urban Light Rail Systems has been questioned; particularly, the use of the A weighted Sound Pressure Level (dB(A)) to assess the impact of noise dominated by low frequency energy. Low frequency noise assessment by the dB(A) has been questioned from a theoretical perspective by examining the origins of the dB(A), and from a practical perspective by reviewing the relevant fieldwork. Sufficient doubt was thought to exist for further studies to be conducted. A series of subjective tests was proposed to assess the ability of the dB(A) to measure the relative annoyance of noises with differing frequency distributions. The available test methods were reviewed and ae set of experiments was designed, based upon the magnitude estimation method. A series of tests was conducted in which subjects were asked to estimate the annoyance of a number of sound stimuli. The dB(A) was found to correlate with the mean annoyance estimates only slightly less well than the Perceived Noisiness Level (PNdB), and significantly better than scales which give greater weight to low frequency noise. The tests are thought to be sufficiently accurate, unbiased and representative for broad conclusions to be drawn, but the relevance of the tests to the problem considered is questioned on the grounds that exposure to low frequency noise can have cumulative side effects.

For different formulations of the TMDs available in the literature, we check the consistency of the TMD matrix elements with the collinear parton distribution functions possessing the well-known operator structure. Comparative on- and off-light-cone layout of the Wilson lines which secure the gauge-invariance of the TMDs is presented and briefly discussed.

Terrain Assessment for High Speed Navigation of Unmanned Ground Vehicles

Subjects: subject: Engineering--Mechanical
subject: Robotics
subject: Unmanned Ground Vehicle
subject: Terrain Assessment
subject: Navigation

description: This thesis proposes a novel terrain assessment technique that is based on an analytical analysis of the vehicle-terrain dynamic interaction. Two geometric characteristics of the terrain: roughness and slope, are addressed in this thesis. Based on such characteristics, two indices are developed in this thesis to assess the Unmanned Ground Vehicle’s (UGV’s) traversability of the terrain quantitatively: Roughness Index (RI) and Stability Index (SI). The RI concept is based on existing remote sensing Geophysics techniques to quantify the effect of the terrain on the UGV. As a result this thesis crosses the bridge between two different disciplines. The proposed RI is a function of the terrain profile and the vehicle’s dynamic and geometric characteristics. A closed form expression of the maximum allowable vehicle speed as function of RI is developed. The proposed SI, on the other hand, is used to represent the vehicle’s stability. In addition of the terrain profile and the vehicle’s characteristics, e.g., centre of gravity and suspension, the SI is also a function of the vehicle state, i.e., speed and radius of turn. The proposed approach used to determine the UGV’s speed is generic enough that it can be employed in and type of ground vehicle. Two selected navigation examples, among the numerous examined, are presented to illustrate the implementation of the proposed terrain assessment technique. The first example illustrates how the proposed terrain assessment can be used to plan the speed of the vehicle while following a given path on an unknown terrain. The second example illustrates the proposed technique used by a UGV to find the optimum path to traverse on a pre-known terrain. Due to its relative simplicity the developed technique can be used in real time to navigate UGVs from point A to point B at the highest (yet safe) vehicle speed while maintaining the integrity of the vehicle. Although the proposed technique is novel and shows great consistency, this thesis concludes with many unanswered questions.

Within this paper I investigate the notion of multiple identities as it applies to Iranian women in relation to different contexts such as history, place, politics and religion. Considering myself a storyteller, my research is based on lived experience and personal observations. I deconstruct visual elements such as Islamic patterns, Farsi texts and self-portraits in the context of culture and history in order to develop my own vocabulary which captures and encodes my states of being and becoming. Focusing on hijab as one of the most powerful forces that shapes women’s identities in Iran, I make visible new identities, which develop in response to the concept of veiling and through acts of protest.

description: Cosmic ray acceleration through first-order Fermi acceleration in a collisionless plasma relies on efficient scattering off magnetic field fluctuations. Scattering is most efficient for magnetic field fluctuations with wavelengths on the order of the gyroradius of the particles. In order to determine the highest energy to which cosmic rays can be accelerated, it is important to understand the growth of the magnetic field on these large scales. We derive the growth rate of the long-wavelength fluctuations in the linear regime, using the kinetic equation coupled to Maxwell's equations for the background plasma. The instability, driven by the cosmic ray current, acts on large scales due to the stress tensor and efficient scattering on small scales, and operates for both left- and right circular polarisations. This long-wavelength instability is potentially important in determining the acceleration efficiency and maximum energy of cosmic rays around shock waves such as in supernova remnants.

description: Nietransparentny proces legislacyjny i niekontrolowany lobbing; ograniczanie dostępu do informacji publicznej; wyłączanie odpowiedzialności i rozliczalności polityków i urzędników za decyzje publiczne oraz dalsze osłabienie administracji publicznej – to główne obszary ryzyk korupcyjnych wskazane w analizie pierwszych czterech tarcz antykryzysowych, opublikowanej przez forumIdei Fundacji Batorego. Walcząc z pandemią COVID-19 rząd zawarł w tzw. „tarczach antykryzysowych” wiele rozwiązań, które nie tylko zwiększają ryzyko korupcji, ale też wydają się zmierzać nie tyle do ograniczenia negatywnych skutków kryzysu, co – przy okazji – do wzmocnienia pozycji obozu władzy. Analiza omawia m.in. rozwiązania, które już na początku pandemii na długi czas wyłączyły możliwość uzyskiwania informacji publicznej. Przez wiele miesięcy obywatele, w tym również dziennikarze, nie mieli swobody w dostępie do informacji o działaniach lokalnych władz i nie mogli reagować, gdyby prowadziły one do nadużyć. W analizie autorzy pokazują również jak szerokie i wielopoziomowe są przepisy „tarcz antykryzysowych” zwalniające funkcjonariuszy publicznych z odpowiedzialności za decyzje dotyczące wydatkowania pieniędzy podatników. To nie tylko tzw. „ustawa o bezkarności”, ale wiele innych przepisów zawartych w tarczach, zwalniających urzędników i polityków z odpowiedzialności za kontrowersyjne decyzje dotyczące przetargów czy dotacji, którym mogła towarzyszyć korupcja. Autorzy opisują również jakie dalekosiężne konsekwencje mogą mieć zawarte w tarczach przepisy pozwalające dokonać zwolnień w administracji rządowej. To za ich pomocą – usprawiedliwiając się walką z pandemią – obóz władzy może dokonać kolejnych czystek w służbie cywilnej i pozbyć się ostatnich, niezależnych, profesjonalnych urzędników, którzy zdołali przetrwać poprzednie fale zwolnień. Jeśli do tego dojdzie, będzie to oznaczać nie tylko pogłębienie upartyjnienia administracji publicznej, ale także osłabienie zdolności państwa do walki z kryzysem.

description: Supersymmetric models with t-b-tau Yukawa coupling unification and unified gaugino masses at the GUT scale with mu >0 show a mild preference for light gluino masses \lesssim 500 GeV. This range of gluino mass is now essentially ruled out by LHC searches. We show that a heavier gluino mass ~ 0.5-3 TeV can also be compatible with excellent t-b-tau Yukawa coupling unification in supersymmetric models with non-universal Higgs masses (NUHM2). The gluino in such models is the lightest colored sparticle, while the squark sector displays an inverted mass hierarchy with m_{\tilde q} ~ 5-20 TeV. We present some LHC testable benchmark points for which the lightest Higgs boson mass ~ 125 GeV. We also discuss LHC signatures of Yukawa-unified models with heavier gluinos. We expect gluino pair production followed by decay to final states containing four b-jets plus four W-bosons plus missing E_T to occur at possibly observable rates at LHC.
Practicing violence : the war of independence in the Mixteca
Creators: name: Schaefer, Timo
Publisher: name: University of British Columbia
Year: 2010

description: In this thesis I investigate the impact of collective violence on local political culture in the Mixteca mountains in Oaxaca during the Mexican War of Independence. I first analyze a number of stories and rumors about the war in Central Mexico that circulated in the Mixteca before the outbreak of hostilities in the region itself for what they reveal about the national imaginings that would condition the local experience of war. I then examine the anti-insurgent campaign of one particular royalist militia company and its fluid relations with local townsmen and villagers, who were the primary pool of new recruits for the company as well as its potential enemies and victims, during the summer of 1814. Coinciding with the rise of a discourse of republican citizenship in Mexico, I show how participation in the militia provided a way for Mixtecan inhabitants of experiencing the new political category ‘citizen’ in practical terms, and thereby established participation in organized violence as a privileged nexus in new articulations between local and national political processes. The overall argument is that armed bands operating in the Mixteca created new institutional spaces connecting local and higher-level political structures and activating practices of citizenship that were premised on participation in military violence.

description: We report X-ray diffraction patterns and calculated electronic band structures of the Dirac line-nodal material CaSb$_2$ under pressure. Its superconducting transition temperature ($T_{\mathrm{c}}=1.7$ K) increases under pressure and reaches a maximum at 3.4 K at around 3 GPa. We observed subtle anomalies in lattice parameters accompanied by a jump in bulk modulus without any change in crystal symmetry at around 3 GPa. First-principles calculations revealed that the distorted lattice of Sb(1) site deforms in the pressure range of 0-3 GPa. Those results suggest the existence of a first-order structural transition and arouse expectations for unusual phononic properties affecting the superconducting state. The calculated pressure dependence of the electronic density of states (DOS) confirms that it is not the change in the DOS that governs the variations in $T_{\mathrm{c}}$.

Impacts of Vanadium and Coke Deposition on CO2 Gasification of Nickel Catalysts Supported on Activated Carbon from Petroleum Coke

description: One of the ways to dispose of spent carbon-based catalysts is gasification. In this study, the kinetics of CO2 gasification of Ni/activated carbon (AC) catalysts, produced from petroleum coke, were investigated at 700-900 °C using a thermogravimetric analyzer (TGA). The catalysts were coked by exposure to ethylene at 400-600 °C and/or impregnated with ~3.5 and 8.5 wt% vanadium, which is typically deposited during hydrodemetalization (HDM) of heavy oil. The gasification rates of all samples were 30-400 times greater than the rate of gasification of uncatalyzed (i.e., no metal) AC. Rate profiles as a function of conversion were different for all samples, which suggested that nickel was promoted/inhibited as a gasification catalyst in different ways depending on the composition of the sample. Transmission electron microscopy was used to analyze samples before and after gasification. The particle morphologies and chemical analysis (energy dispersive X-ray) help to explain the different gasification behaviours. In particular, the nickel particles on the coked Ni/AC sample became encapsulated by graphite and sintered over time from 20 nm initially to 150 nm after 80% conversion (~10 min at 900 °C). After preparation at 500 °C, the AC support was decorated with ~10 nm nickel particles and wetted with a layer of vanadium. After heating to 900 °C, however, sintering of both metals was evident as well as the formation of new vanadium species including vanadium carbide. The interaction between nickel and vanadium lowered the initial gasification rate but also slowed the deactivation of the nickel.

This species is also similar to Tapiena paraincisa Tan & Wahab, 2018 from Brunei Darussalam (not too far from Mount Trus Madi) by its stout body, red (or purple) fore femora and tympanal area (Fig. 32) and stridulatory areas on both tegmina (Figs 33A, 33B), but also differs distinctly by the cercus at its apex broad and flattened (instead of tapering into two tooth-like processes) (Fig. 33C), the tenth abdominal tergite being broadly and truncated and excised in middle (instead of narrowly excised) (Fig. 33D) and the subgenital plate having much shorter apical lobes but longer styli (Fig. 33E) (see also Tan & Wahab, 2018a).
Based on new material from Sabah, it appears that Tan et al. (2019) may have misidentified the Tapiena reported in Lungmanis (near Lahad Datu in Sabah).

description: Leading U.S. food manufacturers typically produce and sell a growing array of food products. Many have also expanded into related wholesale, transportation, and food service industries, while avoiding large-scale involvement in agriculture and food retailing. Diversification by food manufacturers into unrelated product lines declined in the seventies. That decline, coupled with continued increases in diversification into food-related products, led to stabilization in average levels of diversification, after persistent increases since 1919. Successful diversification frequently depends on how readily employees' skills can be transferred to new products. Much recent diversification in the food industries has been based upon the transfer of marketing skills among consumer product industries and technical skills in commodity processing and transportation among producer goods industries.

description: The {\bf H}$_2${\bf O} Southern Galactic {\bf P}lane {\bf S}urvey (HOPS) has observed 100 square degrees of the Galactic plane, using the Mopra radio telescope to search for emission from multiple spectral lines in the 12\,mm band (19.5\,--\,27.5\,GHz). Perhaps the most important of these spectral lines is the 22.2\,GHz water maser transition. We describe the methods used to identify water maser candidates and subsequent confirmation of the sources. Our methods involve a simple determination of likely candidates by searching peak emission maps, utilising the intrinsic nature of water maser emission - spatially unresolved and spectrally narrow-lined. We estimate completeness limits and compare our method with results from the {\sc Duchamp} source finder. We find that the two methods perform similarly. We conclude that the similarity in performance is due to the intrinsic limitation of the noise characteristics of the data. The advantages of our method are that it is slightly more efficient in eliminating spurious detections and is simple to implement. The disadvantage is that it is a manual method of finding sources and so is not practical on datasets much larger than HOPS, or for datasets with extended emission that needs to be characterised. We outline a two-stage method for the most efficient means of finding masers, using {\sc Duchamp}.

description: This thesis investigates the recycling and deactivation of molybdenum sulfide ultra-dispersed catalyst in VGO. An Ultra Dispersed Catalyst Recycling Pilot Plant capable of continuously recycling catalyst was modified and used to carry out this work. A theoretical model to predict catalyst deactivation with time after catalyst cutoff to the plant under recycling operation was developed. The experimental concentration of catalyst followed the decline in catalyst concentration predicted by the theoretical calculation. The effect of operating conditions including space-time, recycle ratio and reaction temperature were investigated and found consistent with results in literature. Under recycle mode of operation, the quality of the hot separator bottoms material was followed with time after catalyst cutoff. As the catalyst concentration declined, the MCR conversion declined disproportionally slower than the catalyst concentration. After three passes through the reactor, the catalyst activity was at or above the activity of fresh catalyst, and thus, did not deactivate.

description: Im Sommer 1812 sah das Russische Reich einer militärischen wie finanziellen Katastrophe entgegen. Noch bevor die napoleonische Grande Armée russisches Territorium betrat, hatte sich das Russische Imperium, erschüttert durch vergangene Kriege, in einer tiefen Schuldenkrise befunden. Mit dem Vormarsch der französischen Truppen geriet das Zarenreich zudem an den Rand der militärischen Niederlage. Russland stand einer doppelten Krise gegenüber – dem drohenden Staatsbankrott wie der erwarteten Eroberung seiner Hauptstadt. Denn anders als die Meistererzählung jüngerer Darstellungen nahelegt, gingen Zar Alexander I. und seine Berater davon aus, Napoleon werde St. Petersburg – und nicht etwa Moskau – angreifen und erobern können. Wie bewältige Zar Alexander I. die Kontingenz der Krise? Der Ungewissheit über den Fortgang des Krieges und der Unsicherheit seiner finanziellen Verteidigungsressourcen, zweier ineinander verschränkter Bedrohungen, begegnete der Zar durch aktives Zukunftshandeln: Binnen weniger Tage verordnete er, Schätze und Geldreserven aus St. Petersburg zu evakuieren und Assignaten in großer Stückzahl zur Kriegsfinanzierung zu drucken. Die Strategien finanzpolitischer und evakuatorischer Prävention lassen erkennen, wie der Zar seinen Staat verstand, wie es seinen Beamten gelang, die Verteidigungs- und Regierungsfähigkeit des Reiches zu wahren und welchen Anteil die zivile Verwaltung daran hatte, die Niederlage Russlands 1812 abzuwenden.

description: The bound-state spectrum of a Hamiltonian H is assumed real in a non-empty domain D of physical values of parameters. This means that for these parameters, H may be called crypto-Hermitian, i.e., made Hermitian via an {\it ad hoc} choice of the inner product in the physical Hilbert space of quantum bound states (i.e., via an {\it ad hoc} construction of the so called metric). The name of quantum catastrophe is then assigned to the N-tuple-exceptional-point crossing, i.e., to the scenario in which we leave domain D along such a path that at the boundary of D, an N-plet of bound state energies degenerates and, subsequently, complexifies. At any fixed $N \geq 2$, this process is simulated via an N by N benchmark effective matrix Hamiltonian H. Finally, it is being assigned such a closed-form metric which is made unique via an N-extrapolation-friendliness requirement.

title: Soil invertebrate and mycorrhizal activity in diverse grasslands: benefits for ecosystem service provision
Creators: name: Shepperd, Sarah

description: Sustainable development goals and net-zero target policies necessitate the progression of livestock production from ryegrass monocultures to grassland diversity. Regenerative agricultural farming techniques could meet nitrogen requirements for grassland systems and enhance their resilience to climate change. Little is known, however, about how plant diversity in farming systems affects the soil and its biota in the short term. This work addresses the knowledge gap by researching the impact of commercially viable diverse forage mixtures on soils and soil biota, all measured within one system. A conventionally fertilised ryegrass monoculture was compared to three unfertilised diverse grasslands differing in plant diversity. Multiple key differences in soil biota were observed as a result of enhancing plant diversity: higher earthworm densities, higher arbuscular mycorrhizal fungi (AMF) root colonisation and higher fungal diversity. A model predicting aboveground biomass production showed that AMF colonisation was the only factor explaining the increase in aboveground biomass at low soil water availability. Additionally, AMF community composition was similar under all diverse mixtures suggesting benefits achieved by AMF presence are equal under a 6 and 17-species grassland. Plant mixtures positively affecting soil microbial community due to their diversity and interspecific competition, especially in environments where future droughts are more likely, will be better at maintaining their productivity as a result of AMF symbiosis increasing the root surface area. Further, the diverse forages investigated in this research reduce the need for external inputs, an outcome with clear and positive implications for farm profitability and environmental impact whilst improving soil health by enhancing abundance and diversity of ecosystem engineers.

Remarks. Our single male specimen mostly resembles S. multa Gorochov & Voltshenkova, 2009. Its male subgenital plate at its posterior end has lateral lobes that are elongated and slender and medial lobes that are very primitive, almost like nodules, not different from S. multa. But in our specimen, the medial lobes are situated at the middle of the posterior margin distinctly apart from lateral lobes (Figs 12C, 12D), unlike that illustrated in Gorochov & Voltshenkova (2009). The median sclerite of the male genitalia is most similar to that of S. multa as suggested by the slender and elongated shape (in ventral view) and bent at nearly 90° (in lateral view) (Figs 12E–G). It is similar to Stictophaula aspersa Gorochov & Voltshenkova, 2009 from Mount Trus Madi and Stictophaula bruneii Tan & Wahab, 2017 from Brunei Darussalam, but slenderer and more elongated at apex (in ventral view). The stridulatory area, including the dark patterns on both tegmina, sinuous shape of the stridulatory file (Fig. 12B) and shape of mirror on the right tegmen, resembles S. multa more than S. aspersa and S. bruneii.

description: We theoretically analyze the noise transformation of a high power continuouswave light field that is reflected off a critical Kerr non-linear cavity (KNLC). Our investigations are based on a rigorous treatment in the time-domain. Thereby, realistic conditions of a specific experimental environment including optical intra-cavity loss and strong classical driving noise can be modeled for any KNLC. We show that even in the presence of optical loss and driving noise considerable squeezing levels can be achieved. We find that the achievable squeezing levels are not limited by the driving noise but solely by the amount of optical loss. Amplitude quadrature squeezing of the reflected mean field is obtained if the KNLC's operating point is chosen properly. Consistently, a KNLC can provide a passive, purely optical reduction of laser power noise as experimentally demonstrated in [1]. We apply our model to this experiment and find good agreement with measured noise spectra.

description: This study sought to improve the understanding of methane ebullition from wetlands by measuring total dissolved gas pressure (Ptdg), volumetric gas content, water pressure, and methane flux from surface chambers between July and September in the shallow part of a wetland. Capillary pressure, which is often ignored in estimating bubbling pressure, contributed up to 5% of the Pbub at shallow depths. Estimated bubbling pressure (Pbub(est)) was a better estimate of free-phase gas than Pbub(ave) given observed variations in Patm and Pw of up to 20 mm Hg. Although Ptdg increased with depth, free-phase gas presence did not vary with depth or time suggesting differential rates of production, retention, and release of gas with depth. Heterogeneities in the peat structure, most significantly the presence of a dense peat layer (~50 cm), contributed to limited agreement between gas-monitoring methods used.
