description: Chronic Obstructive Pulmonary Disease (COPD) is a disease primarily affecting the pulmonary system, most commonly resulting from prolonged exposure to cigarette smoke. While systemic respiratory disturbances in COPD are apparent, the chemical regulation within the brainstem and at the carotid bodies is unclear. Furthermore, the role that cerebral blood flow contributes to respiratory disturbances is poorly understood. Recent studies have demonstrated peripheral vascular impairments in COPD, which may have further implications for exercise –hyperemia. Oxidative stress serves as a plausible mechanism leading to vascular impairments, and the overall increased risk of stroke and cardiovascular disease. This collection of studies set out to define the ventilatory and cerebrovascular responses to acute alterations in PCO2 and PO2 in COPD patients, and the relationship to oxidative stress. A secondary focus was to characterize both cerebral and peripheral blood flow during exercise. The thesis begins by investigating the cerebrovascular and ventilatory responses to acute euoxic-hypercapnia in mild-moderate COPD patients, and the relationship between these physiological parameters, and markers systemic of oxidative stress. Second, the cerebrovascular responses during moderate cycling exercise are defined. The final three studies collectively investigate the effect of the antioxidant, vitamin C, on the cerebrovascular and ventilatory responses to acute hyperoxic-hypercapnia, isocapnic-hypoxia, and on forearm blood flow during handgrip exercise, in COPD patients and healthy controls. This thesis demonstrates that the cerebrovascular and ventilatory responses to hypercapnia, but not hypoxia, are impaired in COPD. Vitamin C was found to augment the ventilatory response to hyperoxic-hypercapnia suggesting oxidative stress contributes to the overall ventilatory limitations in COPD. Dynamic cycling exercise (at a matched relative intensity), evoked a similar cerebrovascular response between COPD and controls, however, a modest increase in workload increased cerebral blood flow in COPD to levels greater than controls, reducing the cerebrovascular reserve capacity. Lastly, forearm blood flow in COPD patients during exercise was similar to controls, and was not affected by vitamin C. Overall, this series of experiments provides a better understanding of the complex systemic consequences of COPD in an integrated nature, thereby advancing knowledge in this important area of study.
Contested water : anti-water privatization movements in Canada and the United States
Creators: name: Robinson, Joanna L.
Publisher: name: University of British Columbia
Year: 2010

description: My dissertation compares two social movements opposed to water privatization in Vancouver, British Columbia, Canada and Stockton, California, United States. While these movements emerged in response to similar global forces and institutions, they developed differently and had divergent outcomes. While the movement in Vancouver successfully prevented the privatization of local water services, the movement in Stockton failed to prevent water services from being privatized, although as a result of a legal challenge the private contract was eventually overturned. Through a qualitative comparative analysis of data from 70 in-depth digitally recorded interviews with movement actors, I identify the specific underlying pathways that explain how cognitive, structural and relational mechanisms combine to shape mobilization, including how activists frame grievances, respond to opportunities, and utilize social networks to achieve their goals. My analysis also illuminates how each of these mechanisms is altered by the interplay between global and local processes, including international institutions and economic opportunity structures. I identify four factors that explain mobilization emergence, trajectories and outcomes in the Vancouver and Stockton cases: 1) context-dependent socially constructed meanings of water, 2) differences in the use of frames, 3) differences in the nature of and responses to political opportunities 4) differences in the strength and cohesion of environmental-labour coalitions. The findings contribute to the sociological understanding of social change in a global era. By revealing how global processes are constituted and reconstituted by local social movements – as well as how they interact with frames, opportunities and networks – my research adds a more nuanced and complete understanding of the specific ways globalization is shaping social movement mobilization on the ground. The creation of local solidarity – achieved through the presence of global connectors and the synthesizing of transnational and situated frames – demonstrates the potential for social movements to move beyond identity or class-based politics to a more broad-based and inclusive counter-hegemonic movement. The findings demonstrate that successful challenges and alternatives to neoliberal globalization will not necessarily come from movements operating at the transnational level, but rather from locally-situated movements that are connected globally but rooted in local communities.

description: Modern smartphones support FIDO2 passwordless authentication using either external security keys or internal biometric authentication, but it is unclear whether users appreciate and accept these new forms of web authentication for their own accounts. We present the first lab study (N=87) comparing platform and roaming authentication on smartphones, determining the practical strengths and weaknesses of FIDO2 as perceived by users in a mobile scenario. Most participants were willing to adopt passwordless authentication during our in-person user study, but closer analysis shows that participants prioritize usability, security, and availability differently depending on the account type. We identify remaining adoption barriers that prevent FIDO2 from succeeding password authentication, such as missing support for contemporary usage patterns, including account delegation and usage on multiple clients.

description: For a quantum many-body system, the direct population of states of double-excitation character is a clear indication that correlations importantly contribute to its nonequilibrium properties. We analyze such correlation-induced transitions by propagating the nonequilibrium Green's functions in real-time within the second Born approximation. As crucial benchmarks, we compute the absorption spectrum of few electrons confined in quantum wells of different width. Our results include the full two-time solution of the Kadanoff-Baym equations as well as of their time-diagonal limit and are compared to Hartree-Fock and exact diagonalization data.
title: Botulinum toxin modulation of mouse bladder sensory afferent signalling
Creators: name: Ibrahim, Hodan
Publisher: name: University of Central Lancashire
Year: 2025

description: This thesis is an investigation of the effects of botulinum neurotoxins (BoNTs) on the ability of the sensory nerves innervating the bladder to detect and transduce mechanical and chemical stimuli. The healthy functioning of the bladder is dependent on the sensory limb of the micturition cycle, and hyperactivation may lead to the development of urgency, a symptom associated with overactive bladder (OAB). Currently, the treatment options for patients with OAB are not ideal, however, injections of BoNT serotype A is a well-tolerated and effective third line treatment. The mechanisms behind the BoNT/A dependent reduction in urgency symptoms are not well understood, and it is unclear how a neurotoxin best known for paralysing the neuromuscular junction may affect the ability of sensory nerves to detect stretch during filling. Using a well-characterised ex vivo mouse electrophysiology preparation where the responses of afferent nerves to bladder filling are recorded directly, a wide variety of BoNT serotypes and recombinant constructs were investigated. In chapter three, studies into the entry mechanisms of BoNT/A into the bladder wall revealed the well-establised double-receptor mechanism was not necessary for internalisation, as the light chain (LC/A) alone significantly inhibited afferent neurotransmission. In chapter four, two other serotypes of BoNT, BoNT/B and BoNT/E were investigated, to understand whether modulation of afferent neurotransmission was a feature specific to BoNT/A. These experiments revealed both BoNTs /B and /E directly inhibited distension-induced firing. In chapter five, the role of SNARE cleavage on BoNT/A induced afferent inhibition was investigated using the catalytically inactive construct BoNT/A (0) unable to cleave SNAP-25. This construct had no effect on hemidiaphragm contractility yet potently inhibited distension induced afferent firing, and was more effective at doing so than catalytically active BoNT/A. These findings are novel and reveal a SNAP-25 independent modulation of sensory signalling.
Facilitating Access and Adherence to Exercise in People with Type 2 Diabetes

description: Exercise is a key component in the management of type 2 diabetes. It improves blood glucose control and quality of life, and reduces cardiovascular events and mortality. Despite the strong evidence demonstrating protective effects of exercise in type 2 diabetes, much of this population remains inactive, and many of those who begin an exercise program do not continue long-term. Finding strategies to support the adoption and long-term adherence to exercise is a valuable endeavor. The aim of this thesis was to examine the effectiveness of motivational interviewing, a potential facilitator to behaviour change and maintenance, together with an examination of pre-exercise stress testing which has been identified as a plausible barrier to supervised exercise programs. This was accomplished through a variety of methods within three distinct studies. These included a systematic review and meta-analysis of motivational interviewing in weight loss interventions, a randomized controlled trial on the effectiveness of motivational interviewing-based counselling to promote maintenance of exercise after the completion of a supervised exercise program, and finally a data linkage study examining the utility of pre-exercise stress testing within a retrospective cohort from a real-world supervised exercise program. The results of the first two studies gave support to use of motivational interviewing as a strategy to improve the effectiveness of weight loss interventions and as an approach to help promote the maintenance of physical activity after a supervised exercise program. In the examination of the use of pre-exercise stress testing, we discovered that the rate of cardiovascular outcomes was low, and that in the few cases where referral for pre-exercise stress testing resulted in a change in care, the patients had multiple cardiac risk factors. These results suggest that improved pre-exercise risk stratification might help identify the small subset of patients with type 2 diabetes likely to benefit from pre-exercise stress testing, thereby streamlining the process prior to the initiation of a supervised exercise program. Within supervised exercise programs, implementing strategies that employ effective facilitators, as well as reduce barriers such as unnecessary testing, may help improve participation and long-term adherence to exercise in people with type 2 diabetes.

description: Since natural resources for the bioproduction of commodity chemicals are scarce, waste animal fats (WAF) are an interesting alternative biogenic residual feedstock. They appear as by-product from meat production, but several challenges are related to their application: first, the high melting points (up to 60 °C); and second, the insolubility in the polar water phase of cultivations. This leads to film and clump formation in shake flasks and microwell plates, which inhibits microbial consumption. In this study, different flask and well designs were investigated to identify the most suitable experimental set-up and further to create an appropriate workflow to achieve the required reproducibility of growth and product synthesis. The dissolved oxygen concentration was measured in-line throughout experiments. It became obvious that the gas mass transfer differed strongly among the shake flask design variants in cultivations with the polyhydroxyalkanoate (PHA) accumulating organism Ralstonia eutropha. A high reproducibility was achieved for certain flask or well plate design variants together with tailored cultivation conditions. Best results were achieved with bottom baffled glass and bottom baffled single-use shake flasks with flat membranes, namely, >6 g L-1 of cell dry weight (CDW) with >80 wt% polyhydroxybutyrate (PHB) from 1 wt% WAF. Improved pre-emulsification conditions for round microwell plates resulted in a production of 14 g L-1 CDW with a PHA content of 70 wt% PHB from 3 wt% WAF. The proposed workflow allows the rapid examination of fat material as feedstock, in the microwell plate and shake flask scale, also beyond PHA production.

description: Using the peer-exposure ratio, we explore the factor exposure heterogeneity in green and brown stocks. By looking at peer groups of S&P 500 index firms over 2014-2020 based on their greenhouse gas emission levels, we find that, on average, green stocks exhibit less factor exposure heterogeneity than brown stocks for most of the traditional equity factors but the value factor. Hence, investment managers shifting their investments from brown stocks to green stocks have less room to differentiate themselves regarding their factor exposures. Finally, we find that factor exposure heterogeneity has increased for green stocks compared to earlier periods.

description: Negative energy scenarios are the most widely studied for the warp metric. In fact, the prevailing view in the community so far has been that the warp metric necessarily has negative energies. In this work it is shown that the issue of negative energy densities associated with the Alcubierre warp metric with a general form function and similar metrics can be addressed when the whole non--vacuum Einstein equations of the system are examined. To this end, we have considered matter content in the form of anisotropic fluids. We have succeeded in writing the Einstein equations in such a way that some general constraints on the material content become evident. This means that, in rectangular coordinates, the energy density depends necessarily on the tangential pressures of the fluid. For matter such as dust or isotropic fluids we find that density and other related quantities become identically zero. This makes the negative energy problem spurious. It is also revealed that constructing Alcubierre-based metrics using cylindrical and spherical coordinates results in a system of equations that are amenable to more systematic analysis. The field equations constrain the dependence of the form function and how this impacts the matter content. In all cases we determine that energy density is not mandatory negative, despite the recurrent claims in the literature.This result prompts a reevaluation of the negative energy requirements and underscore the importance of cylindrical and spherical type-warps to demonstrate that negative energy density is not an intrinsic unavoidable feature of warp drives.

description: The behaviour of the pomeron propagator in the external nuclear field is studied in the (2+1)-dimensional QCD. It is shown that in the physically interesting case when the field does not vanish at large rapidities the propagator in the field vanishes much faster than in the vacuum, in agreement with the results found in the local Regge-Gribov model. However if the nuclear field vanishes at high rapidities the field does not change the behaviour of the pomeron propagator.

description: Negotiation of intergenerational values in first generation immigrant families is the central focus of this study. In-depth interviews were conducted with twenty-two Korean-Canadian participants (six parents and sixteen young adults) in the Greater Toronto Area, followed by data analysis using the grounded theory methods (Strauss & Corbin, 1990). The findings revealed four aspects by which participants effectuate values, and the activities that resolve the tensions embedded in value plurality. The negotiation process also addressed the issues of disconnect, disrespect, and disempowerment in the intergenerational relationship. The quality of parent-child relationship played a meaningful role in participants’ development of values, self-efficacy, and affirmation of identities. Based on the findings of value proficiency and mutual recognition, recommendations are made for service providers to newcomer families, and for educators with particular interest in ethics, diversity and citizenship.

The passage of time and top-down causation

description: It is often claimed that the fundamental laws of physics are deterministic and time-symmetric and that therefore our experience of the passage of time is an illusion. This paper will critically discuss these claims and show that they are based on the misconception that the laws of physics are an exact and complete description of nature. I will argue that all supposedly fundamental deterministic and time-symmetric laws have their limitations and are supplemented by stochastic and irreversible elements. In fact, a deterministic description of a system is valid only as long as interactions with the rest of the world can be ignored. The most famous example is the quantum measurement process that occurs when a quantum system interacts with a macroscopic environment such as a measurement apparatus. This environment determines in a top-down way the possible outcomes of the measurement and their probabilities. I will argue that more generally the possible events that can occur in a system and their probabilities are the result of top-down influences from the wider context. In this way the microscopic level of a system is causally open to influences from the macroscopic environment. In conclusion, indeterminism and irreversibility are the result of a system being embedded in a wider context.

description: This research examines the role of lifelong learning in facilitating successful aging among Chinese older adults. A life history research is adopted to conduct the study. By analyzing narratives of four research participants’ learning stories, the study explores the provision of lifelong learning programs, Chinese perspectives on successful aging, and contributions of lifelong learning to successful aging and active citizenship among Chinese retired older adults. The study shows that the Chinese perspective on successful aging is closely connected to Chinese culture and traditions. Learning contributes to successful aging by bringing out older adults who are healthier, independent, open-minded and socially active. The rich descriptions of historical and political events, Chinese traditions, moralities and social values, contribute to the understanding of Chinese older adults’ pursuit of lifelong learning and perspectives on successful aging. The detailed discussion of the motives and activities of older adults volunteering advances our extant knowledge about Chinese older adults’ volunteerism.

Flares, jets and quasi-periodic outbursts from neutron star merger remnants

Year: 2023
Subjects: subject: High Energy Astrophysical Phenomena (astro-ph.HE)

description: Using numerical relativity simulations with a subgrid dynamo prescription to generate strong initial magnetic fields, we investigate the possibility of launching a jet-like outflow from the hypermassive neutron star (HMNS) during the early stages of the merger, prior to the remnants collapse to a black hole. We demonstrate that buoyant instabilities in the strongly magnetized HMNS can lead to a periodic emission of powerful electromagnetic flares shortly after the merger. These are followed by a collimated mildly relativistic outflow. Both types of outflows feature quasi-periodic kilohertz substructure. These early-time outflows may power precursors to short-duration gamma-ray bursts (SGRB) or in some cases the entire SGRB. While the overall temporal power spectrum we find broadly agrees with the one recently reported for quasi-periodic oscillations in the SGRB GRB910711, our simulations suggest that the periodic electromagnetic substructure is dominated by magnetohydrodynamic shearing processes rather than correlating with the corresponding post-merger gravitational wave signal.

description: We study theoretically the formation spectra of deeply bound pionic atoms expected to be observed by experiments with high energy resolution at RIBF/RIKEN, and we discuss in detail the possibilities to extract new information on the pion properties at finite density from the observed spectra, which may provide information on partial restoration of chiral symmetry in medium. We find that the non-yrast pionic states such as 2s are expected to be seen in the (d,3He) spectra, which will be helpful to reduce uncertainties of the theoretical calculations in the neutron wave functions in nucleus. The observation of the 2s state with the ground 1s state is also helpful to reduce the experimental uncertainties associated in the calibration of the absolute excitation energy. We find that the nuclear densities probed by atomic pions are quite stable and almost constant for various atomic states and various nuclei. Effects of the pion wave function renormalization to the formation spectra are also evaluated.

Pseudoatrophy of the brain in multiple sclerosis : the effect of therapy on T1 measures of brain water content
Creators: name: Mackie, Emilie Ceschi
Publisher: name: University of British Columbia
Year: 2010

description: Magnetic Resonance Imaging (MRI) measures of T₁ relaxation provide a sensitive and reproducible measure of water content in vivo. In the present study T₁ histograms were used to monitor changes in the brain water content of multiple sclerosis (MS) patients initiating Disease Modifying Therapies (DMT). The initiation of DMT, which target inflammation, is associated with a decrease in brain volume (BV) greater than would be expected by natural history alone. Reductions in BV may reflect worsening disease in untreated patients; however for patients treated with DMT, reductions in BV early in the treatment course may represent a clinical improvement due to initial anti-inflammatory effects of therapy and the resulting decrease in edema. The initial change in BV upon starting DMT is termed pseudoatrophy, a reversible decrease in BV due to a loss of water from the brain parenchyma. Patients with clinically definite MS planning on initiating DMT were recruited and scanned at two time points prior to initiating therapy and two time points after initiating therapy to determine the change in water content of the brain.

description: The evolution of heat in crystalline solids is described at low temperatures by the Boltzmann-Peierls-Equation which is a kinetic equation for the phase density of phonons. In this study we solve initial value problems for the Boltzmann-Peierls-Equation with respect to the following questionings: In thermodynamics, a given kinetic equation is usually replaced by its truncated moment systems which in turn is supplemented by a closure principle so that there results a system of PDE's for some moments as thermodynamic variables. A very popular closure principle is the Maximum Entropy Principle yielding a symmetric hyperbolic system. In recent times this strategy has lead to serious studies on two problems that might arise. 1. Do solutions of the Maximum Entropy Principle exist? 2. Is the physics which is embodied in the kinetic equation more or less equivalently displayed by the truncated moment system? It was Junk who proved for the Boltzmann equation of gases that Maximum Entropy solutions do not exist. The same failure appears for the Fokker-Planck-Equation, which was proved by means of explicit solutions by Dreyer/Junk/Kunik. The current study yields a positive existence result. We prove for the Boltzmann-Peierls-Equation hat the Maximum Entropy Principle is well posed and that it can be used to establish a closed hyperbolic moment system of PDE's. Regarding the second question on the equivalence of moments that are calculated by solutions of the Boltzmann-Peierls-Equation and moments that result from the Maximum Entropy system we develop a numerical method that allows a comparison of both solutions. In particular, we introduce a numerical kinetic scheme that consists of free flight periods and two classes of update rules. The first class of rules are the same for the kinetic equation as well as for the Maximum Entropy system, while the second class of update rules contain additional rules for the Maximum Entropy system. It is illustrated that if sufficient many moments are taken into account, both solutions converge to each other. However, it is additionally illustrated, that the numerical effort to solve the kinetic equation is less than the effort to solve the Maximum Entropy system.

Upper critical dimension of the KPZ equation

description: Numerical results for the Directed Polymer model in 1+4 dimensions in various types of disorder are presented. The results are obtained for system size considerably larger than that considered previously. For the extreme strong disorder case (Min-Max system), associated with the Directed Percolation model, the expected value of the meandering exponent, zeta = 0.5 is clearly revealed, with very week finite size effects. For the week disorder case, associated with the KPZ equation, finite size effects are stronger, but the value of seta is clearly seen in the vicinity of 0.57. In systems with "strong disorder" it is expected that the system will cross over sharply from Min-Max behavior at short chains to weak disorder behavior at long chains. This is indeed what we find. These results indicate that 1+4 is not the Upper Critical Dimension (UCD) in the week disorder case, and thus 4+1 does not seem to be the upper critical dimension for the KPZ equation.

Current Administration of Indian Control of Indian Education in Alberta: Implications and Challenges

Subjects: subject: Education--Administration

subject: Case Study

description: This mixed method, exploratory multi-site case study sought to understand the administrative, economic, and political challenges faced by First Nations education directors in Alberta. The purpose was to find out whether (and in what ways) these challenges restrict their capacity to improve the quality of schooling for First Nation children and to identify the roles and responsibilities of education directors who directly administer First Nation schools. The theoretical lens of Tribal Critical Race Theory (TribCrit) underpinned this study. Survey and semi-structured interviews were conducted with 16 education directors in Alberta representing 34 First Nations. This study also found that the processes and procedures put in place, for newly hired education directors to work with, varied between First Nations and were deemed insufficient. Some of the challenges education directors faced included: working with the general education system management, providing instructional leadership; negotiating change; working with a school board, council or oversight body; reporting to a range of internal and external authorities; recruitment and retention of effective teachers; being constrained by federal and provincial mandates, dealing with a perceived crisis in education within First Nation; community pressure for provincial schools to be the preferred schools for students to attend; and support from the parent, community, and agencies for schools was lacking. The most critical and chronic challenge as noted by education directors is the student achievement gap between FN students and other Alberta school students. Also, language and culture programs are not being adequately funded in First Nations. This research revealed that education directors believe First Nations are supportive of Indian Control of Education but perceive the federal government as unsupportive. Critically, the research revealed that the extent and nature of poverty experienced by students affects proper implementation of Indian control of Indian education. Further, the education directors strongly believed that core funding for schooling is grossly inadequate in light of school-based needs. In other words, the failure of the government to provide adequate funding for on-reserve schooling dramatically impeded the capacities of education directors to carry out their roles and responsibilities thereby inhibiting school improvement.
On the Relativistic Invariance of Entanglement

description: In this work we study the entanglement properties under a Lorentz boost of a pair of spin- 1 massive particles, with spin and momentum as the sole degrees of freedom of the system. Different cases for entanglement between spins and momenta are considered as initial states and it is shown that entanglement between the different degrees of freedom is, in general, not invariant. We analyze the entanglement change in terms of the Wigner rotation induced by the transformation and show that, for the case of spin-1 particles, the relative entanglement change between different states depends strongly on the boost velocity.

description: Transitions programs to support non-traditional students have been in existence in Canada since the educational reform movement of the 1970s (Malatest & Associates, 2004). Scholarly research in the success of such programs is frequently presented in terms of institutional directives such as retention and attrition and success is is typically measured by graduation rates. Despite investment in these programs, more than thirty years later there still exists a considerable gap between Indigenous students’ graduation rates and those of their non-Indigenous counterparts, with significant numbers of students dropping out of university programs within the first year (Statistics Canada, 2011). The goal of this exploratory case study was to determine what attributes of the design and structure of a hybrid learning environment encouraged positive persistence decisions. The case was positioned within the first year of an Indigenous Pre-Nursing Transitions (PNT) program in a western Canadian university. Scholarly literature on persistence and community models such as Tinto’s (1975) Student Integration Model and Wenger’s (1998) Community of Practice were evaluated for their applicability to non-traditional students. Data collection took place over one academic year and consisted of interviews with student and faculty participants, as well as observation of online activities within two required biology courses. The results of this case study demonstrated the complexity of community membership for Indigenous students. Further, the results highlighted the importance of a one-to-one relationship with the instructor and student expectations about this relationship. Other factors that contributed to positive persistence decisions were scale of the environment and structure of course content.

description: This document is our reply to the Comment (Miloslav Znojil 2023 J. Phys. A: Math. Theor. 56, 038001) on our recent work titled `The operational foundations of PT-symmetric and quasi-Hermitian quantum theory'. The original Comment consists of three addenda to our work. The first addendum claims that our work is ill-motivated as the motivating question, namely whether PT-symmetric quantum theory extends the standard quantum theory, was already answered in the literature. The second addendum points to some missing references in our work, and the third addendum suggests what constraints could lead to an extension of standard quantum theory. In our reply, we explain that the claim in the first addendum is a result of a misinterpretation of our motivating question. When interpreted correctly, the third addendum in the Comment in itself elaborates on why our motivating question is interesting and relevant. We also briefly comment on the prospects of an extension of standard quantum theory along the lines suggested in the third addendum. As our response to the second addendum, we explain our rationale behind citing certain references while leaving out others.

description: We derive an uncertainty relation for the energy density and pressure of a quantum scalar field in a time-dependent, homogeneous and isotropic, classical background, which implies the existence of large fluctuations comparable to their vacuum expectation values. A similar uncertainty relation is known to hold for the field square since the field can be viewed as a Gaussian random variable. We discuss possible implications of these results for the reheating process in scalar field driven inflationary models, where reheating is achieved by the decay of the coherently oscillating inflaton field. Specifically we argue that the evolution after backreaction can seriously be altered by the existence of these fluctuations. For example, in one model the coherence of the inflaton oscillations is found to be completely lost in a very short time after backreaction starts. Therefore we argue that entering a smooth phase in thermal equilibrium is questionable in such models and reheating might destroy the smoothness attained by inflation.
