Non-covalent control of mammalian acetyl-CoA carboxylase isoforms
Creators: name: Lee, Weissy Michelle
Publisher: name: University of British Columbia
Year: 2010

description: Acetyl-CoA carboxylase (ACC) plays several crucial roles in lipid metabolism and has been identified as a potential drug target for the treatment of obesity and cancer. Many aspects of ACC structure, function and control remain unclear and my general goal was to provide new insights into two unresolved areas. The first part of this thesis describes work to characterize the key allosteric site that is responsible for citrate-induced ACC activation. The second area addressed is the hypothesis that protein-protein interactions provide critical aspects of ACC control. The effects of citrate on ACC were probed by studying the effects of pyridoxal phosphate (PLP), modeled on earlier studies of phosphofructokinase. A comprehensive assessment of the inhibition kinetics of ACC by PLP provides support for the effects of PLP being non-competitive with respect to substrates and therefore perhaps mediated by binding to a non-catalytic site. Further studies established methods for covalent attachment of PLP via Schiff base reduction with sodium borohydride and set the stage for more precise localization of PLP binding. To define proteins that interact specifically with ACC, techniques were established to separate large polymeric forms of ACC from smaller dimeric forms of the enzyme by size exclusion chromatography. Analysis of the citrate-induced ACC polymers by tandem mass spectrometry led to the identification of a small number of proteins that consistently associated with ACC in a citrate-dependent manner, including fatty acid synthase (FASN) and tubulin. The interactions of ACC with FASN and tubulin were further explored by Western blotting, co-immunoprecipitation, ACC activity assays and immunofluorescence analysis of primary rat hepatocytes. The evidence from several complementary experimental approaches supports specific interactions between ACC and tubulin. Tubulin appears to have subtle effects on ACC catalytic activity and may be more critical for structural organization and cellular localization of ACC. Immunofluorescence microscopy of ACC within primary rat hepatocytes led to novel insights, notably that ACC is localized into discrete structures rather than being distributed through the cytosolic compartment. This work opens the way to further characterization of the relevant subcellular structures and the role this localization plays in the control of ACC isoforms.

description: For a list assignment $L$ and an $L$-coloring $φ$, a Kempe swap in $φ$ is \emph{$L$-valid} if it yields another $L$-coloring. Two $L$-colorings are \emph{$L$-equivalent} if we can form one from another by a sequence of $L$-valid Kempe swaps. And a graph $G$ is \emph{$L$-swappable} if every two of its $L$-colorings are $L$-equivalent. We consider $L$-swappability of line graphs of planar graphs with large maximum degree. Let $G$ be a planar graph with $Δ(G)\ge 9$ and let $H$ be the line graph of $G$. If $L$ is a $(Δ(G)+1)$-assignment to $H$, then $H$ is $L$-swappable. Let $G$ be a planar graph with $Δ(G)\ge 15$ and let $H$ be the line graph of $G$. If $L$ is a $Δ(G)$-assignment to $H$, then $H$ is $L$-swappable. The first result is analogous to one for $L$-choosability by Borodin, which was later strengthened by Bonamy. The second result is analogous to another for $L$-choosability by Borodin, which was later strengthened by Borodin, Kostochka, and Woodall.

description: By virtue of their spectral types, favourable bolometric corrections as well as their constrained distances, post-AGB stars in external galaxies offer unprecedented tests to AGB nucleosynthesis and dredge-up predictions. We focus here on one object J004441.04-732136.4, which is the only known 21 micrometer source of the SMC. Spectral abundance results reveal J004441.04-732136.4 to be one of the most s-process enriched objects found up to date, while the photospheric C/O ratio of 1.9 +- 0.7, shows the star is only modestly C-rich. J004441.04-732136.4 also displays a low [Fe/H] = -1.34 +- 0.32, which is significantly lower than the mean metallicity of the SMC. From the SED, a luminosity of 7600 +- 200 solar luminosities is found, together with E(B-V) = 0.64 +- 0.02. According to evolutionary post-AGB tracks, the initial mass should be approximately 1.3 solar masses. The photometric variability shows a clear period of 97.6 +- 0.3 days. The detected C/O as well as the high s-process overabundances (e.g. [Y/Fe] = 2.15, [La/Fe] = 2.84) are hard to reconcile with the predictions. The chemical models also predict a high Pb abundance, which is not compatible with the detected spectrum, and a very high 12C/13C, which is not yet constrained by observations. The predictions are only marginally dependent on the evolution codes used. We show that our theoretical predictions match the s-process distribution, but fail in reproducing the detected high overabundances and predict a high Pb abundance which is not detected. Additionally, there remain serious problems in explaining the observed pulsational properties of this source.

description: Let $X$ be a regular tame stack. If $X$ is locally of finite type over a field, we prove that the essential dimension of $X$ is equal to its generic essential dimension, this generalizes a previous result of P. Brosnan, Z. Reichstein and the second author. Now suppose that $X$ is locally of finite type over a $1$-dimensional noetherian local domain $R$ with fraction field $K$ and residue field $k$. We prove that $\operatorname{ed}_{k}X_{k} \le \operatorname{ed}_{K}X_{K}$ if $X\to \operatorname{Spec} R$ is smooth and $\operatorname{ed}_{k}X_{k} \le \operatorname{ed}_{K}X_{K}+1$ in general.

description: The T2K experiment is a long baseline neutrino oscillation experiment aiming to observe the appearance of ν e in a νμ beam. The νμ beam is produced at the Japan Proton Accelerator Research Complex (J-PARC), observed with the 295 km distant Super- Kamiokande Detector and monitored by a suite of near detectors at 280m from the proton target. The near detectors include a magnetized off-axis detector (ND280) which measures the un-oscillated neutrino flux and neutrino cross sections. The present paper describes the outermost component of ND280 which is a side muon range detector (SMRD) composed of scintillation counters with embedded wavelength shifting fibers and Multi-Pixel Photon Counter read-out. The components, performance and response of the SMRD are presented.

description: Smart windows, dynamically adjusting optical transmittance, face global adoption challenges due to climatic and economic variability. Aiming these issues, we synthesized a methyl cellulose (MC) salt system with high tunability for intrinsic optical transmittance (89.3%), which can be applied globally to various locations. Specifically, the MC window has superior heat shielding potential below transition temperatures while turning opaque at temperatures above the Lower Critical Solution Temperature (LCST), reducing the solar heat gain by 55%. Such optical tunability is attributable to the particle size change triggered by the temperature-induced reversible coil-to-globular transition. This leads to effective refractive index and scattering modulation, making them prospective solutions for light management systems, an application ahead of intelligent fenestration systems. MC-based windows demonstrated a 9°C temperature decrease compared to double-pane windows on sunny days and a 5°C increase during winters in field tests, while simulations predict an 11% energy savings.Incorporating MC-based phase change materials in passive solar panels indicated optimized energy efficiency, offering a sustainable alternative. Real-time simulations validate practical applicability in large-scale solar panels. Furthermore, a temperature-responsive sorbent with a dark layer demonstrates an optimal optical and water uptake performance. Transitioning between radiative cooling and solar heating, the sorbent exhibits high water harvesting efficiency in lab and field tests. With an adjustable LCST at 38 ℃, the cellulose-based sorbent presents a potential solution for atmospheric water harvesting, combining optical switching and temperature responsiveness for sustainable water access. Furthermore, the ubiquitous availability of materials, low cost, and ease-of-manufacturing will provide technological equity and foster our ambition towards net-zero buildings and sustainable future.

description: To calculate the magnetic ground state of nanoparticles we present a self-consistent first principles method in terms of a fully relativistic embedded cluster multiple scattering Green's function technique. Based on the derivatives of the band energy, a Newton-Raphson algorithm is used to find the ground state configuration. The method is applied to a cobalt nanocontact that turned out to show a cycloidal domain wall configuration between oppositely magnetized leads. We found that a wall of cycloidal spin-structure is about 30 meV lower in energy than the one of helical spin-structure. A detailed analysis revealed that the uniaxial on-site anisotropy of the central atom is mainly responsible to this energy difference. This high uniaxial anisotropy energy is accompanied by a huge enhancement and anisotropy of the orbital magnetic moment of the central atom. By varying the magnetic orientation at the central atom, we identified the term related to exchange couplings (Weiss-field term), various on-site anisotropy terms, and also those due to higher order spin-interactions.

Effect of mixed Saccharomyces strain fermentation on Pinot noir wine
Creators: name: Terrell, Emily Elizabeth
Publisher: name: University of British Columbia
Year: 2010

description: Pinot noir has traditionally been fermented by native winery flora; however, the recent practice of single yeast strain inoculation may simplify wine aromas and flavours. Thus, a need exists for yeasts that create the complexity of naturally fermented wines and provide the consistency of commercial strains. It has been suggested that mixed Saccharomyces strains may be capable of this dual role. In this study, three novel Burgundian S. cerevisiae strains were characterized for enological equivalency against five industrial strains recommended for Pinot noir. The volatile compounds produced by these strains along with four Burgundian strain mixtures were quantified in Pinot noir wine to evaluate the hypothesis that mixed S. cerevisiae strains contribute to the complexity of naturally fermented wine. The Burgundian strains were enologically equivalent to the industrial strains in terms of killer phenotype, fermentation kinetics, production of ethanol, glycerol, and acetic acid, conversion of sugar to ethanol, ethanol tolerance, foam production, sulfur dioxide production, and compatibility with malolactic fermentation. The concentrations of most of the 25 compounds quantified in the headspace of Pinot noir wines fermented at 22°C and 27°C significantly differed among yeast strains and between temperatures. Principal component analysis revealed different patterns of volatile production among the industrial, individual Burgundian and mixed Burgundian yeast strains. Mixed Burgundian strains produced greater amounts of most of the higher alcohols than individual Burgundian strains. Additionally, individual and mixed Burgundian strains produced greater amounts of ethyl esters than most industrial strains, but did not differ from one another. In contrast, the pattern of acetate ester production differed between individual Burgundian and mixed Burgundian strains in a fermentation temperature-dependent manner. Cluster analysis revealed that differences in the patterns of volatile production among industrial, individual Burgundian and mixed Burgundian yeast strains extended over the complete volatile profile. Furthermore, cluster analysis of the averaged profiles showed greater overall similarity between the industrial and the individual Burgundian strains than the mixed Burgundian strains. Fermenting Pinot noir with mixed Burgundian yeast strains resulted in unique patterns of volatile production, which holds promise for mixed Saccharomyces products that yield wines of greater complexity.

description: The compound EuFe(2-x)Co(x)As2 was investigated by means of the 57Fe and 151Eu Moessbauer spectroscopy versus temperature (4.2 - 300 K) for x=0 (parent), x=0.34 - 0.39 (superconductor) and x=0.58 (overdoped). It was found that spin density wave (SDW) is suppressed by Co-substitution, however it survives in the region of superconductivity, but iron spectra exhibit some non-magnetic component in the superconducting region. Europium orders anti-ferromagnetically regardless of the Co concentration with the spin re-orientation from the a-axis in the parent compound toward c-axis with the increasing replacement of iron by cobalt. The re-orientation takes place close to the a-c plane. Some trivalent europium appears in EuFe(2-x)Co(x)As2 versus substitution due to the chemical pressure induced by Co-atoms and it experiences some transferred hyperfine field from Eu2+. Iron experiences some transferred field due to the europium ordering for substituted samples in the SDW and non-magnetic state both, while the transferred field is undetectable in the parent compound. Superconductivity coexists with the 4f-europium magnetic order within the same volume. It seems that superconductivity has some filamentary character in EuFe(2-x)Co(x)As2 and it is confined to the non-magnetic component seen by the iron Moessbauer spectroscopy.

description: We study almost hypercomplex skew-Hermitian structures and almost quaternionic skew-Hermitian structures, as the geometric structures underlying $\mathsf{SO}^\ast(2n)$- and $\mathsf{SO}^\ast(2n)\mathsf{Sp}(1)$-structures, respectively. The corresponding intrinsic torsions were computed in the previous article in this series, and the algebraic types of the geometries were derived, together with the minimal adapted connections (with respect to certain normalizations conditions). Here we use these results to present the related first-order integrability conditions in terms of the algebraic types and other constructions. In particular, we use distinguished connections to provide a more geometric interpretation of the presented integrability conditions and highlight some features of certain classes. The second main contribution of this note is the illustration of several specific types of such geometries via a variety of examples. We use the bundle of Weyl structures and describe examples of $\mathsf{SO}^\ast(2n)\mathsf{Sp}(1)$-structures in terms of functorial constructions in the context of parabolic geometries.

description: We present a new Kondo-lattice system, YbNi4P2, which is a clean heavy-fermion metal with a severely reduced ferromagnetic ordering temperature at T_C=0.17K, evidenced by distinct anomalies in susceptibility, specific-heat, and resistivity measurements. The ferromagnetic nature of the transition, with only a small ordered moment of ~0.05mu_B, is established by a diverging susceptibility at T_C with huge absolute values in the ferromagnetically ordered state, severely reduced by small magnetic fields. Furthermore, YbNi4P2 is a stoichiometric system with a quasi-one-dimensional crystal and electronic structure and strong correlation effects which dominate the low temperature properties. This is reflected by a stronger-than-logarithmically diverging Sommerfeld coefficient and a linear-in-T resistivity above T_C which cannot be explained by any current theoretical predictions. These exciting characteristics are unique among all correlated electron systems and make this an interesting material for further in-depth investigations.

description: The Equivalence Principle (EP) is at the heart of General Relativity (GR), tested in many aspects. It is often used to discuss qualitatively the influence of gravity on physical phenomena. But can this be made more precise? We compare clock rates, frequency shifts, light deflection and time delay in simple static spacetimes to the analogous phenomena seen by accelerated observers in Minkowski space. In contrast to previous studies, we do not assume that the gravitational field is weak and see, as we proceed, how the field is constrained by the EP. Special care is taken that results are only observer-, but not coordinate-dependent. By this we clarify some of the issues raised in the literature and show which gravitational effects can and which cannot be simulated by acceleration. The paper may also serve as a contribution for critical discussions on the implications of the EP.

description: Mottness is at the heart of the essential physics in a strongly correlated system as many novel quantum phenomena occur in the metallic phase near the Mott metal-insulator transition. We investigate the Mott transition in a Hubbard model by using the dynamical mean-field theory and introduce the local quantum state fidelity to depict the Mott metal-insulator transition. The local quantum state fidelity provides a convenient approach for determining the critical point of the Mott transition. Additionally, it presents a consistent description of the two distinct forms of the Mott transition points.

A numerical study of boson star binaries
Creators: name: Mundim, Bruno Coutinho
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes a numerical study of binary boson stars within the context of an approximation to general relativity. Boson stars, which are static, gravitationally bound configurations of a massive complex scalar field, can be made gravitationally compact. Astrophysically, the study of gravitationally compact binaries---in which each constituent is either a neutron star or a black hole---and especially the merger of the constituents that generically results from gravitational wave emission, continues to be of great interest. Such mergers are among the most energetic phenomena thought to occur in our universe. They typically emit copious amounts of gravitational radiation, and are thus excellent candidates for early detection by current and future gravitational wave experiments. The approximation we adopt places certain restrictions on the dynamical variables of general relativity (conformal flatness of the 3-metric), and on the time-slicing of the spacetime (maximal slicing), and has been previously used in the simulation of neutron stars mergers. The resulting modeling problem requires the solution of a coupled nonlinear system of 4 hyperbolic, and 5 elliptic partial differential equations (PDEs) in three space dimensions and time. We approximately solve this system as an initial-boundary value problem, using finite difference techniques and well known, computationally efficient numerical algorithms such as the multigrid method in the case of the elliptic equations. Careful attention is paid to the issue of code validation, and a key part of the thesis is the demonstration that, as the basic scale of finite difference discretization is reduced, our numerical code generates results that converge to a solution of the continuum system of PDEs as desired. The thesis concludes with a discussion of results from some initial explorations of the orbital dynamics of boson star binaries. In particular, we describe calculations in which motion of such a binary is followed for more than two orbital periods, which is a significant advance over previous studies. We also present results from computations in which the boson stars merge, and where there is evidence for black hole formation.

description: We have successfully fabricated Cu/AlOx-Al/Nb normal-metal/insulator/superconductor tunnel junction devices with a high value of the superconducting gap (up to $\sim 1$ mV), using electron-beam lithography and angle evaporation techniques in the sub-micron scale. The subgap conductance of these junctions shows the expected strong temperature dependence, rendering them suitable for thermometry all the way from 100 mK to 6 K. In addition, some direct electronic cooling of the normal metal was also seen at bias values near the gap edge. The device performance was strongly influenced by the details of the Al layer geometry, with lateral spilling of the aluminium giving rise to strong extra subgap features, and the thickness of Al layer affecting the proximised superconducting gap value of the superconducting Al/Nb bilayer.

description: Using density-functional calculations, we study the effect of sp$^3$-type defects created by different covalent functionalizations on the electronic and magnetic properties of graphene. We find that the induced magnetic properties are {\it universal}, in the sense that they are largely independent on the particular adsorbates considered. When a weakly-polar single covalent bond is established with the layer, a local spin-moment of 1.0 $μ_B$ always appears in graphene. This effect is similar to that of H adsorption, which saturates one $p_z$ orbital in the carbon layer. The magnetic couplings between the adsorbates show a strong dependence on the graphene sublattice of chemisorption. Molecules adsorbed at the same sublattice couple ferromagnetically, with an exchange interaction that decays very slowly with distance, while no magnetism is found for adsorbates at opposite sublattices. Similar magnetic properties are obtained if several $p_z$ orbitals are saturated simultaneously by the adsorption of a large molecule. These results might open new routes to engineer the magnetic properties of graphene derivatives by chemical means.

description: We compute the logarithmic correction to the entropy of asymptotically AdS$_4$ black holes in minimal ${\cal N}=2$ gauged supergravity. We show that for extremal black holes the logarithmic correction computed in the near horizon geometry agrees with the result in the full geometry up to zero mode contributions, thus clarifying where the quantum degrees of freedom lie in AdS spacetimes. In contrast to flat space, we observe that the logarithmic correction for supersymmetric black holes can be non-topological in AdS as it is controlled by additional four-derivative terms other than the Euler density. The available microscopic data and results in 11d supergravity indicate that the full logarithmic correction is topological, which suggests that the topological nature of logarithmic corrections could serve as a diagnosis of whether a low-energy gravity theory admits an ultraviolet completion.

description: Recently, a decelerator for neutral polar molecules has been presented that operates on the basis of macroscopic, three-dimensional, traveling electrostatic traps (Osterwalder et al., Phys. Rev. A 81, 051401 (2010)). In the present paper, a complete description of this decelerator is given, with emphasis on the electronics and the mechanical design. Experimental results showing the transverse velocity distributions of guided molecules are shown and compared to trajectory simulations. An assessment of non-adiabatic losses is made by comparing the deceleration signals from 13-CO with those from 12-CO and with simulated signals.

Health of people with spinal cord injury in Singapore : the implications for rehabilitation planning and implementation
Creators: name: Teo, Sock Hui Joy
Publisher: name: University of British Columbia

description: Background: Knowledge about the health of people living with spinal cord injuries (SCIs) in the community is lacking in Singapore. Purpose: To describe the health of people with SCI in Singapore and formulate recommendations for long-term rehabilitation planning and implementation. Methods: This was a cross-sectional descriptive study of people living with traumatic SCI in Singapore. Demographic data, injury information and information about SCI-related secondary impairments, chronic conditions and their associated risk factors, medical and hospital utilization, participation (Craig Handicap Assessment and Reporting Technique [CHART]) and life satisfaction (Satisfaction with Life Scale [SWLS]) were collected through telephone or in-person interviews. Participants were stratified according to presence or absence of a full-time live in carer, time since injury, injury type and participation in regular exercise. Post-hoc comparisons were conducted for these groups. The association between participation and life satisfaction was examined. Results: On average, participants (50 men and 5 women) were aged 48.3±16.54 years and had had their SCIs for 5 years. Three quarters (78.2%) had tetraplegia. The most prevalent SCI-related secondary impairments were pain, spasms, bladder problems, bowel problems and edema. The prevalence of chronic conditions and their associated risk factors was greater among the participants than reported for Singaporeans overall. The prevalence of diabetes and hypertension was 9.1% and 10.9%, respectively. Almost a quarter of participants were told by doctors that they were overweight and/or had high cholesterol. One quarter (25.5%) of participants reported exercising regularly. The prevalence of binge drinking and daily smoking was 5.5% and 12.7%, respectively. Mean CHART scores ranged between 32.2 and 88.4 with lowest scores in the ‘occupation’ dimension. The mean SWLS score was 13.9. Participation and life satisfaction scores were lower than those reported for similar populations cross-culturally. Conclusion: People with SCI in Singapore may be less healthy than the population overall. Our findings support the need for a registry and database to help track the changing needs of this population over time with the aim to increase the quality of life of people with SCI in Singapore and, in turn, help minimize long-term social and economic burdens for the country.
Social Movements, Technological Solutions to Problems, and Political Conflict: The Case of Alternative Proteins
Creators: name: Hall, Russell
Publisher: name: Purdue University Graduate School

subject: Political science not elsewhere classified

description: New technologies are often developed to address pressing social problems such as climate change and world hunger, and social movements are often strong backers of these technological solutions. Yet political conflict can occur when those threatened by the new technology seek government action to block or delay its adoption. I analyze forces behind the development of such technologies and factors affecting the outcomes of ensuing political conflicts through an in-depth study of alternative or “alt-proteins,” plant-based and cell-cultured alternatives to traditional meat and dairy products. Developed to address the environmental and animal welfare problems of animal agriculture, alt-proteins have generated political conflict as livestock and dairy interests have sought regulations to limit producers’ ability to market alt-proteins as substitutes for meat and dairy products. My research uncovers a network of organizations founded by animal welfare interest groups and activists that provide direct and coordinated support for alt-protein technology development and industry growth. Besides government lobbying, activities include founding and financing start-ups, supporting basic research, and providing various business supports to the industry. Early successes by some alt-protein companies have led dairy and livestock farmers to lobby the U.S. and state governments for protectionist labeling policies. While one might expect other businesses involved in the production and distribution of meat and dairy products to join in these efforts, I found this was often not the case. To explain this finding, I propose that the formation of a strong coalition to seek government support in opposing a new technology depends not only on businesses’ reliance on the old technology, but also on the cost to the businesses of diversifying into the new technology and on the speed with which the new technology is displacing the old. My research also shows how a social movement’s embrace of technological solutions to problems may fundamentally alter its strategies and coalition partners in both political and market spheres. In their quest to attract investment capital, organizations founded by animal welfare groups worked with large food companies to invest in alt-proteins but alienated some in other social movements. The latter fear that expensive technologies will further control of the food system by large corporations, illustrating the potential divisiveness of technological solutions to problems. I assess the effects of coalition building on outcomes of policy conflicts over alt-proteins and consider the applicability of this case to other situations.
A Lichnerowicz estimate for the first eigenvalue of convex domains in Kähler manifolds

description: In this article, we prove a Lichnerowicz estimate for a compact convex domain of a Kähler manifold whose Ricci curvature satisfies $\Ric \ge k$ for some constant $k>0$. When equality is achieved, the boundary of the domain is totally geodesic and there exists a nontrivial holomorphic vector field. We show that a ball of sufficiently large radius in complex projective space provides an example of a strongly pseudoconvex domain which is not convex, and for which the Lichnerowicz estimate fails.

Hubble distancing: Focusing on distance measurements in cosmology

description: The Hubble-Lemaitre tension is currently one of the most important questions in cosmology. Most of the focus so far has been on reconciling the Hubble constant value inferred from detailed cosmic microwave background measurement with that from the local distance ladder. This emphasis on one number -- namely $H_0$ -- misses the fact that the tension fundamentally arises from disagreements of distance measurements. To be successful, a proposed cosmological model must accurately fit these distances rather than simply infer a given value of $H_0$. Using the newly developed likelihood package `distanceladder', which integrates the local distance ladder into MontePython, we show that focusing on $H_0$ at the expense of distances can lead to the spurious detection of new physics in models which change late-time cosmology. As such, we encourage the observational cosmology community to make their actual distance measurements broadly available to model builders instead of simply quoting their derived Hubble constant values.

description: Quantum and thermal fluctuations of an irrotational fluid are studied across the transition regime connecting a protoinflationary phase of decelerated expansion to an accelerated epoch driven by a single inflaton field. The protoinflationary inhomogeneities are suppressed when the transition to the slow roll phase occurs sharply over space-like hypersurfaces of constant energy density. If the transition is delayed, the interaction of the quasi-normal modes related, asymptotically, to fluid phonons and inflaton quanta leads to an enhancement of curvature perturbations. It is shown that the dynamics of the fluctuations across the protoinflationary boundaries is determined by the monotonicity properties of the pump fields controlling the energy transfer between the background geometry and the quasi-normal modes of the fluctuations. After corroborating the analytical arguments with explicit numerical examples, general lessons are drawn on the classification of the protoinflationary transition.
