description: This manuscript presents a new framework towards automated digital documentation and progress reporting of mechanical pipes in building construction projects, using smartphones. New methods were proposed to optimize video frame rate to achieve a desired image overlap; define metric scale for 3D reconstruction; extract pipes from point clouds; and classify pipes according to their planned bill of quantity radii. The effectiveness of the proposed methods in both laboratory (six pipes) and construction site (58 pipes) conditions was evaluated. It was observed that the proposed metric scale definition achieved sub-millimeter pipe radius estimation accuracy. Both laboratory and field experiments revealed that increasing the defined image overlap improved point cloud quality, pipe classification quality, and pipe radius/length estimation. Overall, it was found possible to achieve pipe classification F-measure, radius estimation accuracy, and length estimation percent error of 96.4%, 5.4mm, and 5.0%, respectively, on construction sites using at least 95% image overlap.

description: Ptychography is a lensless imaging method that allows for wavefront sensing and phase-sensitive microscopy from a set of diffraction patterns. Recently, it has been shown that the optimization task in ptychography can be achieved via automatic differentiation (AD). Here, we propose an open-access AD-based framework implemented with TensorFlow, a popular machine learning library. Using simulations, we show that our AD-based framework performs comparably to a state-of-the-art implementation of the momentum-accelerated ptychographic iterative engine (mPIE) in terms of reconstruction speed and quality. AD-based approaches provide great flexibility, as we demonstrate by setting the reconstruction distance as a trainable parameter. Lastly, we experimentally demonstrate that our framework faithfully reconstructs a biological specimen.

description: This paper develops a stochastic model for comparing payments to U.S. corn producers of a revenue-based counter-cyclical payment (R-CCP) that is offered as an alternative in the 2007 House "Farm Bill" (H.R. 2419) to the current price-based CCP (P-CCP). We minimize the potential for miss-specification bias in the model by using nonparametric and semi-nonparametric approaches as specification checks in the model. Using this model, the paper examines the sensitivity of the density function for payments to changes in expected price levels. A mean-variance utility function approach is used to assess producer preferences for choice of CCP program alternative. The results show that as risk reduction instruments at the farm level, there appears to be little effective difference between the P-CCP and the R-CCP. At the national level, however, the R-CCP has the potential for increasing Federal budgetary exposure relative to the P-CCP when expected prices are low.
An interpretive description of the experience of end stage renal disease as perceived by persons with diabetes mellitus
Creators: name: Ravenscroft, Eleanor Fay
Publisher: name: University of British Columbia
Year: 2009

description: I designed this study to explore the experience of end stage renal disease (ESRD) from the perspective of people with diabetes. My intent was to increase the knowledge, awareness, and understanding of the experience of ESRD for individuals with diabetes. I used the qualitative research approach, interpretive description, described by Thorne, Reimer Kirkham, and MacDonald-Emes (1997), as my research method as it was appropriate to answering the research question, "How do individuals with diabetes experience ESRD?" The data were collected by means of in-depth interviews with a total of 7 participants ranging in age from 35 to 87 years. All of the participants had been receiving dialysis treatments for at least 2 years prior to this study. The interview transcripts constituted the bulk of the data. Inductive data analysis was ongoing throughout the data collection process. The cumulative analytic findings informed and guided the data collection process enabling the construction of the interpretive description. The narratives constructed through the research interviews revealed three dominant themes within the participants' perception of the experience of diabetes and ESRD. These were the experience of diagnosis, the experience of illness intrusion, and the experience of interactions with health care providers. Further, in describing how they engaged with the illness experience, participants described how they sought and maintained control over the illness experience as they adjusted to living with ESRD. Participants adjusted to living with ESRD by learning to manage through minimizing illness intrusion, thinking positively, learning to manage diabetes with ESRD, and learning by experience. In addition, participants described how they sought to find a balance between the illness and normalcy and reached an acceptance of illness through hope. The findings of this study support the existing understanding of the experience of ESRD as relevant to persons with diabetes and ESRD. However, the findings also strengthen the argument for individualized care based on the lived experience of the individual. Implications for future nursing research include further exploration of selected issues that emerged from the findings and evaluation of care delivery within hemodialysis programs.

description: For physical human-robot interactions (pHRI), a robot needs to estimate the accurate body pose of a target person. However, in these pHRI scenarios, the robot cannot fully observe the target person's body with equipped cameras because the target person must be close to the robot for physical interaction. This close distance leads to severe truncation and occlusions and thus results in poor accuracy of human pose estimation. For better accuracy in this challenging environment, we propose an active measurement and sensor fusion framework of the equipped cameras with touch and ranging sensors such as 2D LiDAR. Touch and ranging sensor measurements are sparse but reliable and informative cues for localizing human body parts. In our active measurement process, camera viewpoints and sensor placements are dynamically optimized to measure body parts with higher estimation uncertainty, which is closely related to truncation or occlusion. In our sensor fusion process, assuming that the measurements of touch and ranging sensors are more reliable than the camera-based estimations, we fuse the sensor measurements to the camera-based estimated pose by aligning the estimated pose towards the measured points. Our proposed method outperformed previous methods on the standard occlusion benchmark with simulated active measurement. Furthermore, our method reliably estimated human poses using a real robot, even with practical constraints such as occlusion by blankets.

description: We investigate the doubly bottom state $T^-_{bb}$ composed of two bottom mesons with $J^P=1^+$. The potentials are obtained using the one-boson exchange model. With the heavy quark flavor symmetry, all the parameters in the model are determined by fitting the experimental data of doubly charmed state $T_{cc}^{+}$ from our previous work. Our analysis indicates that the isospin symmetry is well-preserved. We identify a deeply bound $T^-_{bb}$ state with quantum numbers $I(J^{P})=0(1^+)$, in contrast to the loosely bound $T_{cc}^{+}$. Additionally, we discover a resonant $T^-_{bb}$ state with $I(J^{P})=1(1^+)$. Furthermore, our investigation into the $\bar{B}\bar{B}^*$-$\bar{B}^*\bar{B}^*$ coupled channel effect reveals its important impact. The binding energy of the bound $I(J^{P})=0(1^+)$ states becomes deeper, while the resonant $T^-_{bb}$ state with $I(J^{P})=1(1^+)$ remains nearly unchanged.

description: Two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs) are good candidates for high-performance flexible electronics. However, most demonstrations of such flexible field-effect transistors (FETs) to date have been on the micron scale, not benefitting from the short-channel advantages of 2D-TMDs. Here, we demonstrate flexible monolayer MoS2 FETs with the shortest channels reported to date (down to 50 nm) and remarkably high on-current (up to 470 uA/um at 1 V drain-to-source voltage) which is comparable to flexible graphene or crystalline silicon FETs. This is achieved using a new transfer method wherein contacts are initially patterned on the rigid TMD growth substrate with nanoscale lithography, then coated with a polyimide (PI) film which becomes the flexible substrate after release, with the contacts and TMD. We also apply this transfer process to other TMDs, reporting the first flexible FETs with MoSe2 and record on-current for flexible WSe2 FETs. These achievements push 2D semiconductors closer to a technology for low-power and high-performance flexible electronics.

description: This study evaluates the effects of grain output price uncertainty on the farm income of rural households and, consequently, how this uncertainty influences caloric intake through changes in farm income. Using a rural household data set, augmented with output price uncertainty measures calculated from historical time-series data, we find that grain output price uncertainty tends to decrease crop production income of rural households. In addition, we find that higher crop income from production increases calorie intake of rural households. Taken together, these results suggests that output price uncertainty during the production process may tend to reduce caloric intake of rural Nepalese households since the price uncertainty negatively affects the crop income households need to buy calorie-rich staple foods.

description: Using $5.8 \times 10^7 J/ψ$ events collected in the BESII detector, the radiative decay $J/ψ\to γϕϕ\to γK^+ K^- K^0_S K^0_L$ is studied. The $ϕϕ$ invariant mass distribution exhibits a near-threshold enhancement that peaks around 2.24 GeV/$c^{2}$. A partial wave analysis shows that the structure is dominated by a $0^{-+}$ state ($η(2225)$) with a mass of $2.24^{+0.03}_{-0.02}{}^{+0.03}_{-0.02}$ GeV/$c^{2}$ and a width of $0.19 \pm 0.03^{+0.06}_{-0.04}$ GeV/$c^{2}$. The product branching fraction is: $Br(J/ψ\to γη(2225))\cdot Br(η(2225)\to ϕϕ) = (4.4 \pm 0.4 \pm 0.8)\times 10^{-4}$.

description: The mechanical properties of magnetic materials are instrumental for the development of the magnetoelastic theory and the optimization of strain-modulated magnetic devices. In particular, two-dimensional (2D) magnets hold promise to enlarge these concepts into the realm of low-dimensional physics and ultrathin devices. However, no experimental study on the intrinsic mechanical properties of the archetypal 2D magnet family of the chromium trihalides has thus far been performed. Here, we report the room temperature layer-dependent mechanical properties of atomically thin CrI3 and CrCl3, finding that bilayers of CrI3 and CrCl3 have Young's moduli of 62.1 GPa and 43.4 GPa, with the highest sustained strain of 6.09% and 6.49% and breaking strengths of 3.6 GPa and 2.2 GPa, respectively. Both the elasticity and strength of the two materials decrease with increased thickness, which is attributed to a weak interlayer interaction that enables interlayer sliding under low levels of applied load. The mechanical properties observed in the few-layer chromium trihalide crystals provide evidence of outstanding plasticity in these materials, which is qualitatively demonstrated in their bulk counterparts. This study will contribute to various applications of the van der Waals magnetic materials, especially for their use in magnetostrictive and flexible devices.

description: If a magnetic field is frozen into a plasma that undergoes spherical compression then the magnetic field B varies with the plasma density ρaccording to B \propto ρ^{2/3}. In the gravitational collapse of cosmological density perturbations, however, quasi-spherical evolution is very unlikely. In anisotropic collapses the magnetic field can be a much steeper function of gas density than in the isotropic case. We investigate the distribution of amplifications in realistic gravitational collapses from Gaussian initial fluctuations using the Zel'dovich approximation. Representing our results using a relation of the form B\propto ρ^α, we show that the median value of αcan be much larger than the α=2/3 resulting from spherical collapse, even if there is no initial correlation between magnetic field and principal collapse directions. These analytic arguments go some way towards understanding the results of numerical simulations.

description: Degli scavi archeologici realizzati dall’Institut National de Recherches Archéologiques Préventives nel 2008 - 2009 sul sito del « boulevard du docteur Henri Henrot », a Reims, hanno permesso di studiare, su un fronte di circa 40 m, l’organizzazione della riva destra del corso d’acqua che, in età romana, costeggiava la capitale della Gallia Belgica. Numerosi reperti indicano che, nel III sec d.C., questo quartiere periferico della città aveva vocazione artigianale. Sembra anche che, all’inizio del I sec. d.C. il settore non fosse ancora urbanizzato. Le prime tracce della sua frequentazione a quel tempo consistono in tre fosse. Lo scavo, parziale, di queste strutture ha permesso di constatare che esse contenevano essenzialmente delle ossa di equini, delle quali circa 1600 sono state studiate. In questo lavoro sono presentate le principali caratteristiche dei campioni faunistici e sono poi discussi i risultati dello studio tafonomico dei reperti, dal quale appare, fra l’altro, che le carcasse degli animali sono state sottoposte a una lavorazione orientata al recupero di materie prime da destinare all’artigianato.

Résumé

Des fouilles réalisées par l’Institut National de Recherches Archéologiques Préventives en 2008 - 2009 sur le site du « boulevard du docteur Henri Henrot », à Reims, ont permis d’étudier, sur une quarantaine de mètres de longueur, l’ancien aménagement de la rive droite de la Vesle, le cours d’eau au bord duquel s’est installée la capitale de la Gaule Belgique. Des nombreuses évidences archéologiques indiquent qu’au IIIe s. ap. J.C. ce quartier périphérique de la ville avait vocation artisanale. Il apparaît également qu’au début du Ier s. ap. J.C. le secteur n’était pas encore urbanisé. Les premières traces de sa fréquentation à cette époque consistent en trois fosses. La fouille, partielle, de ces structures a permis de constater qu’elles contenaient essentiellement des restes d’équidés, dont un peu moins de 1600 ont été étudiés. Dans ce travail sont présentées les principales caractéristiques des échantillons fauniques et sont ensuite discutés les résultats de l’étude taphonomique des ossements, d’où il ressort, entre autre, que les carcasses des animaux ont été soumises à des manipulations orientées vers la récupération de matières premières à destiner à l’artisanat.

description: The invasion of ecosystems by non-native species is widely considered to be a principal threat to global biological diversity, yet the social costs of invasive species are not well-understood. The purpose of this study is to estimate a hedonic model of lakeshore property values to quantify the effects of a common aquatic invasive species â€“ Eurasian Watermilfoil â€“ on property values across an extensive system of over 170 lakes in the northern forest region of Wisconsin. In addition to providing empirical evidence as to the potential benefits from reducing the spread of invasive species, this paper also develops a quasi-experimental methodology to identify the effects of changes in endogenous neighborhood amenities within the commonly estimated hedonic framework. In our application, a lake is more likely to be invaded with Milfoil if it is more popular with recreational boaters. Therefore, since lakes popular with recreational boaters are also likely to be popular with potential residents, and since many aspects of a lakeâ€™s amenities may be difficult to quantify, the likelihood of Milfoil invasions is endogenous in a hedonic price equation. Our identification strategy is based on a spatial difference-in-difference specification, and uses fixed effects to control for observed and unobserved neighborhood effects, while exploiting changes in the Milfoil status of several lakes during the time period of our data. Results indicate that lakes invaded with Milfoil experienced an average 13% decrease in land values after invasion. The Milfoil results are robust across linear and non-linear specifications.

description: This study investigates the role of nutrition and ingredients information, included in the food labels, as useful tools for individuals who are trying to lose weight. This research has three objectives - examine personal characteristics as predictors of willingness to lose weight conditional on individual's current body mass index, investigate whether those who are trying to lose weight are more likely to read food labels to gather nutritional and ingredients information, and, analyze whether those who want to lose weight and read food labels have a greater propensity to lose weight. Estimates from random effects logistic regressions indicate higher usage of food labels by those who are trying to lose weight, irrespective of their current body mass index. There is also greater likelihood of weight loss in the user group. Future research entails use of more sophisticated econometric techniques to control for self-selection and endogeneity.
Common envelope evolution through planetary nebula eyes

description: The common envelope interaction is responsible for evolved close binaries. Among them are a minority of central stars of planetary nebula (PN). Recent observational results, however, point to most PN actually being in binary systems. We therefore ask the question if it is feasible that most, or even all Galactic PN derive from a common envelope interaction. Our recent calculation finds that if all single and binary primary stars with mass between ~1-8 Mo eject a PN, there would be many more PN in the galaxy than observed. On the other hand, the predicted number of post-common envelope PN is more in agreement with the total number of PN in the Galaxy. This is a new indication that binary interactions play a functional role in the creation of PN and an encouragement to intensify efforts to detect binary companions.

description: Decoding algorithms based on approximate tensor network contraction have proven tremendously successful in decoding 2D local quantum codes such as surface/toric codes and color codes, effectively achieving optimal decoding accuracy. In this work, we introduce several techniques to generalize tensor network decoding to higher dimensions so that it can be applied to 3D codes as well as 2D codes with noisy syndrome measurements (phenomenological noise or circuit-level noise). The three-dimensional case is significantly more challenging than 2D, as the involved approximate tensor contraction is dramatically less well-behaved than its 2D counterpart. Nonetheless, we numerically demonstrate that the decoding accuracy of our approach outperforms state-of-the-art decoders on the 3D surface code, both in the point and loop sectors, as well as for depolarizing noise. Our techniques could prove useful in near-term experimental demonstrations of quantum error correction, when decoding is to be performed offline and accuracy is of utmost importance. To this end, we show how tensor network decoding can be applied to circuit-level noise and demonstrate that it outperforms the matching decoder on the rotated surface code.

description: How well can multiple incompatible observables be implemented by a single measurement? This is a fundamental problem in quantum mechanics with wide implications for the performance optimization of numerous tasks in quantum information science. While existing studies have been mostly focusing on the approximation of two observables with a single measurement, in practice multiple observables are often encountered, for which the errors of the approximations are little understood. Here we provide a framework to study the implementation of an arbitrary finite number of observables with a single measurement. Our methodology yields novel analytical bounds on the errors of these implementations, significantly advancing our understanding of this fundamental problem. Additionally, we introduce a more stringent bound utilizing semi-definite programming that, in the context of two observables, generates an analytical bound tighter than previously known bounds. The derived bounds have direct applications in assessing the trade-off between the precision of estimating multiple parameters in quantum metrology, an area with crucial theoretical and practical implications. To validate the validity of our findings, we conducted experimental verification using a superconducting quantum processor. This experimental validation not only confirms the theoretical results but also effectively bridges the gap between the derived bounds and empirical data obtained from real-world experiments. Our work paves the way for optimizing various tasks in quantum information science that involve multiple noncommutative observables.

It cuts both ways : Freud, Lacan and the fragmented body
Creators: name: Soros, Erin
Publisher: name: University of British Columbia
Year: 2009

description: "It Cuts Both Ways: Freud, Lacan and the Fragmented Body" is a thesis written in pieces. Four sections give a reading of corporeal fragmentation, each layered with yet challenging the other, forming a work that comes together as it falls apart. The first section explores Jacques Lacan's Ethics of Psychoanalysis, specifically the concepts of sublimation, das Ding, and the death drive, in order to analyse how it is that an object can so increase in value—can promise such dangerous, impossible pleasure—that one would risk one's death simply to tear it up. This section is followed by a reading of Sigmund Freud's The Ego and the Id, an explication of some of this text's most productive contradictions. Freud asserts that a child identifies with a parent as a compensation against the loss of an object-cathexis: when this suggestion is taken to its logical conclusion it serves to undermine the possibility of a boy's heterosexual identification. I analyse the possible results of a boy identifying not with his father but with his mother, an identification accepted then rejected then projected onto his own daughter, onto a body the now grown boy can better control. The next section addresses Freud's Beyond the Pleasure Principle, focussing on Freud's theory of the compulsion to repeat, where representation of a trauma gains momentum unhinged from the origin it can only represent, binding the invasion of stimuli only as it binds the subject to death. Freud suggests that tearing apart a body is a means to create one: I ask how it happens that the means overtakes the end, when destroying the body becomes its own return. The thesis concludes with an exploration of several key concepts as outlined by Lacan: the mirror stage, the drive, objet a, and the relationship between the real, the imaginary and the symbolic. My aim here is to explore what structures form the body and what is lost through this formation, when corporeality is cut and cuts back.

description: A global multi-commodity simulation model was developed to estimate the impact of changes in ethanol production on the U.S. corn industry. Increased ethanol production under the Energy Acts of 2005 and 2007 resulted in a significant increase in the price of corn. However, for corn-based ethanol production, the break-even price of corn is approximately $4.52 per bushel with a federal subsidy of $0.51 per gallon of pure ethanol and $2.50 gasoline. With a corn price of $4.52, the economically desirable ethanol production is approximately 11 billion gallons. In order to produce 15 billion gallons of corn-based ethanol and to maintain the price of corn at $4.52 per bushel, supply of corn in the U.S. should be increased substantially through increases in corn yield rather than increases in corn acres. The increased price of corn leads to major structural changes in the corn industry in the United States as well as other corn producing and consuming countries. Corn production would increase in response to higher price levels, corn used for livestock feed may decrease, and U.S. exports decrease due mainly to a surge in corn used for ethanol production. This decrease in U.S. exports should be met by additional production in other countries. The increased price of corn also leads to increases in the prices of soybeans, wheat, high fructose corn syrup (HFCS), and agricultural inputs, such as land value and cash rent, fertilizer and chemicals, and farm equipment. In addition, the current price of corn has resulted in an increase in the production cost of livestock. The increase in prices of agricultural commodities and inputs would cause increases in retail prices of food in the U.S.

description: We study the back-action of a single photon detector on the electromagnetic field upon a photodetection by considering a microscopic model in which the detector is constituted of a sensor and an amplification mechanism. Using the quantum trajectories approach we determine the Quantum Jump Superoperator (QJS) that describes the action of the detector on the field state immediately after the photocount. The resulting QJS consists of two parts: the bright counts term, representing the real photoabsorptions, and the dark counts term, representing the amplification of intrinsic excitations inside the detector. First we compare our results for the counting rates to experimental data, showing a good agreement. Then we point out that by modifying the field frequency one can engineer the form of QJS, obtaining the QJS's proposed previously in an ad hoc manner.

$P_{cs}(4459)$ and other possible molecular states from $Ξ_{c}^{(*)}\bar{D}^{(*)}$ and $Ξ'_c\bar{D}^{(*)}$ interactions

description: Recently, the LHCb Collaboration reported a new structure $P_{cs}(4459)$ with a mass of 19 MeV below the $Ξ_c \bar{D}^{*} $ threshold. It may be a candidate of molecular state from the $Ξ_c \bar{D}^{*} $ interaction. In the current work, we perform a coupled-channel study of the $Ξ_c^*\bar{D}^*$, $Ξ'_c\bar{D}^*$, $Ξ^*_c\bar{D}$, $Ξ_c\bar{D}^*$, $Ξ'_c\bar{D}$, and $Ξ_c\bar{D}$ interactions in the quasipotential Bethe-Salpeter equation approach. With the help of the heavy quark chiral effective Lagrangian, the potential is constructed by light meson exchanges. Two $Ξ_c \bar{D}^{*} $ molecular states are produced with spin parities $ J^P=1/2^-$ and $3/2^- $. The lower state with $3/2^-$ can be related to the observed $P_{cs}(4450)$ while two-peak structure cannot be excluded. Within the same model, other strange hidden-charm pentaquarks are also predicted. Two states with spin parities $1/2^-$ and $3/2^-$ are predicted near the $Ξ'_c\bar{D}$, $Ξ_c\bar{D}$, and $Ξ_c^*\bar{D}$ thresholds, respectively. As two states near $Ξ_c \bar{D}^{*}$ threshold, two states are produced with $1/2^-$ and $3/2^-$ near the $Ξ'_c\bar{D}^*$ threshold. The couplings of the molecular states to the considered channels are also discussed. The experimental research of those states are helpful to understand the origin and internal structure of the $P_{cs}$ and $P_c$ states.

description: Standard procedures for entanglement detection assume that experimenters can exactly implement specific quantum measurements. Here, we depart from such idealizations and investigate, in both theory and experiment, the detection of genuine multipartite entanglement when measurements are subject to small imperfections. For arbitrary qubits number $n$, we construct multipartite entanglement witnesses where the detrimental influence of the imperfection is independent of $n$. In a tabletop four-partite photonic experiment we demonstrate first how a small amount of alignment error can undermine the conclusions drawn from standard entanglement witnesses, and then perform the correction analysis. Furthermore, since we consider quantum devices that are trusted but not perfectly controlled, we showcase advantages in terms of noise resilience as compared to device-independent models.

description: We take a structural approach to examine the effects of larger container size on consumption of carbonated soft drinks---using Nielsen Company's Homescan data on household purchases for the years 2004 through 2006. Our results show that by removing the price discount implicit in packages with larger container size, the average unit price the two households pay for CSD products increase and hence both households (both the low income and the high income) reduce their annual consumption of soft drinks by about 75%. This reduction is due to a combination of reduced number of purchases and switching to products with less number of bottles/cans.

description: We show that light scalars can form quasibound states around binaries. In the nonrelativistic regime, these states are formally described by the quantum-mechanical Schrodinger equation for a one-electron heteronuclear diatomic molecule. We performed extensive numerical simulations of scalar fields around black hole binaries showing that a scalar structure condenses around the binary -- we dub these states "gravitational molecules". We further show that these are well described by the perturbative, nonrelativistic description.

description: We provide a framework to estimate the systematic uncertainties in chemical freeze-out parameters extracted from $χ^2$ analysis of thermal model, using hadron multiplicity ratios in relativistic heavy-ion collision experiments. Using a well known technique of graph theory, we construct all possible sets of independent ratios from available hadron yields and perform $χ^2$ minimization on each set. We show that even for ten hadron yields, one obtains a large number ($10^8$) of independent sets which results in a distribution of extracted freeze-out parameters. We analyze these distributions and compare our results for chemical freeze-out parameters and associated systematic uncertainties with previous results available in the literature.

description: We consider real univariate degree $d$ real-rooted polynomials with non-vanishing coefficients. Descartes' rule of signs implies that such a polynomial has $\tilde{c}$ positive and $\tilde{p}$ negative roots counted with multiplicity, where $\tilde{c}$ and $\tilde{p}$ are the numbers of sign changes and sign preservations in the sequence of its coefficients, $\tilde{c}+\tilde{p}=d$. For $d=6$, we give the exhaustive answer to the question: When the moduli of all $6$ roots are distinct and arranged on the real positive half-axis, in which positions can the moduli of the negative roots be depending on the signs of the coefficients?
Tunneling in a quantum field theory on a compact one-dimensional space

description: We compute tunneling in a quantum field theory in 1+1 dimensions for a field potential $U(Φ)$ of the asymmetric double well type. The system is localized initially in the ``false vacuum''. We consider the case of a {\em compact space} ($S_1$) and study {\em global} tunneling. The process is studied in real-time simulations. The computation is based on the time-dependent Hartree-Fock variational principle with a product {\em ansatz} for the wave functions of the various normal modes. While the wave functions of the nonzero momentum modes are treated within the Gaussian approximation, the wave function of the zero mode that tunnels between the two wells is not restricted to be Gaussian, but evolves according to a standard Schrödinger equation. We find that in general tunneling occurs in a resonant way, the resonances being associated with degeneracies of the approximate levels in the two separated wells. If the nonzero momentum modes of the quantum field are excited only weakly, the phenomena resemble those of quantum mechanics with the wave function of the zero mode oscillating forth and back between the wells. If the nonzero momentum modes are excited efficiently, they react back onto the zero mode causing an effective dissipation. In some region of parameter space this back-reaction causes the potential barrier to disappear temporarily or definitely, the tunneling towards the ``true vacuum'' is then replaced by a sliding of the wave function.
