description: Use of curvilinear coordinates is sometimes indicated by the inherent geometry of a fluid dynamics problem, but this introduces fictitious forces into the momentum equations that spoil strict conservative form. If one is willing to work in three dimensions, these fictitious forces can be eliminated by solving for rectangular (Cartesian) momentum components on a curvilinear mesh. A thoroughly geometric approach to fluid dynamics on spacetime demonstrates this transparently, while also giving insight into a greater unity of the relativistic and nonrelativistic cases than is usually appreciated.

Reflected Backward Stochastic Differential Equations for Informational Systems with Applications
Creators: Alsheyab,  Safa' Mahmoud
Publisher: name: University of Alberta Library
Year: 2022

The core innovation of this thesis lies in studying reflected backward stochastic differential equations (RBSDE hereafter) for informational systems.  An informational system is a system where there is discrepancy in the information received by agents over time. In this thesis, we restrict to the case where our system is governed by two flows of informations: The public information F that is available to all agents and a larger flow of information G that has additional information about a random time T. We mathematically formulate our results in a general setting where T might not be observable by the flow of information F. This allows our results to be applicable to credit risk theory, to life insurance where mortality and longevity risks are the main challenges, to financial models with arbitrary random horizon, ..., etcetera. Thus, we study RBSDEs that are stopped at T, and consider G to be the progressive enlargement of F with T, where T becomes an observable time when it occurs (a stopping time with respect to G mathematically speaking). In this setting, we quantify --as explicit as possible-- the impact of T on the existence, the uniqueness, and the estimate in norm of the solution of the RBSDE stopped at T. We construct an RBSDE under F that is intimately related to the stopped one, and we single out the exact relationship between their solutions. Importantly, we prove that for any random time, having a positive Az\'ema supermartingale, there exists a positive discount factor E, which is a positive and non-increasing F-adapted and RCLL process, that is vital in proving our results without assuming any further assumption on T. We treat both the linear and general cases of RBSDEs for bounded and unbounded horizon.

description: Selectivity of olfactory receptor neuron (ORN) is compared with that of its receptor proteins (R) with fluctuations of odor binding-releasing process taken into account. The binding-releasing process is modeled as N Bernoulli trials, where N is the total number of R per ORN. Dimensionless selectivities for both R and ORN are introduced and compared with each other. It is found the ORN's selectivity can be much higher then that of its receptor proteins. This effect is concentration-dependent. Possible application for biosensors is discussed.

Transcription Factor Dysfunction in Ovarian Cancer: The Role of ZIC2 and RUNX3
Creators: Chen, Huachen
Publisher: name: University of Alberta Library
Year: 2022

Ovarian cancer is the most lethal gynecological cancer, and epithelial ovarian cancer (EOC) accounts for about 90% of ovarian cancers. Despite advancements in medical technology, the overall survival rate of EOC has improved only slightly, with a 5-year survival rate of less than 50%. One cause is the development of chemoresistance in EOC after conventional chemotherapy, which may be due to the presence of cancer stem cells (CSCs). ZIC2 is a transcription factor that is expressed in embryonic stem cells but not in adult tissues except the brain and testis. Upregulation of ZIC2 is pro-tumorigenic in a variety of human cancers. However, limited studies have been conducted on ZIC2-mediated regulation of tumorigenic phenotypes and the related molecular mechanisms of ZIC2 in EOC. We hypothesized that ZIC2 promotes tumorigenic phenotypes in EOC. Herein, we reported that ZIC2 is expressed in a subpopulation of EOC samples and is associated with poor survival in patients with advanced EOC. ZIC2 promotes cell growth, single-cell survival, anchorage-independent growth, and CSC stemness, but it is cell-context dependent. Furthermore, we demonstrated potential underlying mechanisms for ZIC2-mediated regulation of tumorigenic phenotypes in EOC.We also investigated the role of the transcription factor RUNX3 in a rare subtype of ovarian cancer, granulosa cell tumor of the ovary (GCT). GCTs are classified as adult granulosa cell tumors (AGCT) and juvenile granulosa cell tumors (JGCT). Although most GCTs are diagnosed at early stages, patients with advanced GCTs have a poor prognosis and are prone to relapse. RUNX3 has been shown to play an important role in normal tissues and human cancers. RUNX3 plays a role in inhibiting or promoting tumor progression in various human cancers. In EOC, RUNX3 promotes cell proliferation, anchorage-independent growth, and chemoresistance. We hypothesized that RUNX3 promotes the tumorigenic phenotypes in GCT. We reported the expression of RUNX1, RUNX2, and RUNX3 in GCT, where RUNX3 showed low levels of variable expression in GCT samples but not in the normal human granulosa cell line SVOG or normal ovarian tissues. RUNX3 also promotes cell growth, anchorage-independent growth, cell motility, and tumor formation in the AGCT cell line KGN, while inhibition of RUNX3 in the JGCT cell line COV434 reduces cell growth. Moreover, RUNX3 upregulates the expression of cyclin D2 and reduces the expression of P27Kip1 in KGN cells. Collectively, this study suggests that ZIC2 and RUNX3 play a pro-tumorigenic role in ovarian cancer in a context-dependent manner and are potential therapeutic targets for ovarian cancer.
Cholinergic projections to the preBötzinger Complex
Creators: Yang, Xiaqiu
Publisher: name: University of Alberta Library
Year: 2022

Breathing is a vital behavior regulated by the brainstem neurons. To maintain regular ventilation, these neurons need to establish proper interactions with other neurons and process signals transmitted by various neurotransmitters. Located in the ventrolateral medulla, the neurons in the preBötzinger Complex (preBötC) are essential for respiratory rhythmogenesis. Cholinergic neurotransmission influences the activity of preBötC and affects the activity of rhythmic respiratory neurons. However, the source of cholinergic inputs to the preBötC and the roles of those projections are not fully understood. Using transgenic ChAT-Cre mouse line, Cre-depended viruses, combinatorial genetics, and state-of-the-art technologies, we investigated the cholinergic connections of the preBötC. In our study, we injected the HSV into the preBötC of ChAT-Cre mice to non-specifically label the neurons projecting to the preBötC, and the retrograde Cre-dependent virus to specifically label cholinergic neurons. Then, we use microscopy to qualitatively and quantitatively analyze the distribution of the retrogradely labeled neurons. Furthermore, we injected the anterograde Cre dependent virus into the pedunculopontine tegmental nucleus and laterodorsal tegmentum (PPT/LDT), two cholinergic structures proposed to provide cholinergic inputs to preBötC neurons of ChAT-Cre mice and analyzed the labeled axons within the preBötC. We observed that cholinergic inputs to the preBötC are primarily from the neighboring regions including lateral paragigantocellular nucleus (LPGi) and nucleus ambiguus (NA), while the preBötC receives few cholinergic inputs from the brainstem major cholinergic nuclei PPT/LDT. Our study provides the anatomical foundation to help researchers further investigate the cholinergic modulation of respiration, the physiological roles of cholinergic neurons adjacent to the preBötC, and the cardiorespiratory disorders related to cholinergic dysfunction.

description: We develop a classically verifiable scheme for blindly factorizing the semiprime 21 quantumly for a classical client who does not trust the remote quantum servers. Our scheme advances state of the art, which achieves blind factorization of 15 quantumly, by increasing the problem to factorizing the next semiprime, choosing a harder base, executing a non-Clifford gate, and showing that the security check for 15 also works for 21. Our algorithmic approach to incorporating non-Clifford operations sets the stage for scaling blind quantum factorization, whereas our five-EPR-pair scheme motivates a photonic experiment that supplants current demonstrations of blind factorization.

Supercooling in Rivers: Field Measurements and Surface Energy Budget Analysis
Creators: Boyd, Sean Ryan
Publisher: name: University of Alberta Library
Year: 2022

The process of supercooling, where turbulent water is cooled below freezing while remaining a liquid, is a necessary condition for the formation of frazil and anchor ice in northern rivers during the late fall and winter. While the phenomenon has been often investigated in laboratory, relatively few studies report field observations. This thesis reports on 696 supercooling events recorded on three regulated Alberta rivers from 2015 – 2020. These supercooling events were analyzed for properties including peak supercooling temperature and duration, and analyzed in order to increase our understanding of the behaviour of supercooling in rivers. The median peak supercooling temperature across all events was -0.013oC and a median cooling rate of -2.5x10-4 oC/minute. Though the median event duration was 4.8 hours, events with durations from 2 to 14 days were regularly observed, exceeding the longest events previously reported in literature of ~50 hours. Preliminary analysis of longitudinal gradient of supercooling events in rivers showed the potential impact of both dam regulation and urbanization on spatial distribution of supercooling. Comparison between the behaviour of supercooling on left and right bank in one river showed differences in frequency and duration of supercooling events cross channel, which may have additional implications for the spatial distribution of frazil ice production.

Since supercooling events are driven by climate factors of the late fall and winter, understanding the heat fluxes at the water surface and how they drive supercooling is crucial to improving understanding of supercooling. Supercooling data collected on two rivers for the 2016-2017 season was analyzed along side local weather data to provide insight into the relationship between supercooling events and the local surface energy budget. From the calculated shortwave, longwave, sensible, and evaporative heat fluxes, it was found that the shortwave and longwave were the dominant heat fluxes during supercooling events, with 97.4 % of events predominantly warmed by shortwave radiation, and 80.0 % of events predominantly cooled by longwave radiation. Sensible heat flux was found to primarily be a secondary heat flux unless air temperature dropped significantly colder that the season average (average air temperature -14.8 oC during supercooling compared to the season average of -8.99 oC during supercooling). Evaporative heat flux tended to be negligible unless air temperature was positive along side high wind speeds and low magnitude radiative heat fluxes. While no linear correlation was found between supercooling parameters and event averaged heat flux components, it is clear from the analysis that the start and end of supercooling events are notably impacted by the diurnal cycling of shortwave radiation.

description: This work aims to design a CMOS compatible, low-electrical power consumption modulator assisted by plasmons. For compactness and reduction of the electrical power consumption, electro-absorption based on the Franz-Keldysh effect in Germanium was chosen for modulation. It consists in the change of the absorption coefficient of the material near the band edge under the application of a static electric field, hence producing a direct modulation of the light intensity. The use of plasmons allows enhancing the electro-optical effect due to the high field confinement. An integrated electro-optical simulation tool was developed to design and optimize the modulator. The designed plasmonic modulator has an extinction ratio of 3.3 dB with insertion losses of 13.2 dB and electrical power consumption as low as 20 fJ/bit, i.e. the lowest electrical power consumption reported for silicon photonic modulators. In- and out-coupling to a standard silicon waveguide was also engineered by the means of an optimized Si-Ge taper, reducing the coupling losses to only 1 dB per coupler. Besides, an experimental work was carried out to try to shift the Franz-Keldysh effect, which is maximum at 1650 nm, to lower wavelength close to 1.55 μm for telecommunication applications.

Morphology of Zihuateutla Totonac
Creators: Garcia-Vega, Michelle
Publisher: name: University of Alberta Library
Year: 2022

This dissertation presents a description of the morphology and phonology of Zihuateutla Totonac (ZT), a member of the Northern branch of the Totonacan (Totonac-Tepehua) language family.  Zihuateutla Totonac is spoken by about 1,100 people in northern Puebla State, Mexico. Previous to this study, ZT had no description of its linguistic features, and its relationship to other languages in the family has been poorly understood. Based on a documentation project conducted between 2013 and 2017, this research contributes to our knowledge of the unique linguistic properties of ZT that distinguishes it from other languages in the family. The outcome of this project includes a phrasal and textual corpus, a lexical database, and a detailed description of major phonological and morphological patterns. This description covers an overview of basic syntactic structures, the phonemic inventory, and general phonological processes. The bulk of this thesis involves the morphological patterns of the main word classes (verbs, nouns, adjectives, numerals, and adverbs). Of typological importance is the highly polysynthetic and agglutinative verbal morphology of ZT, which encodes categories for inflection and derivation, and categories that do not fall in either of these two domains. Nouns, adjectives, numerals, and adverbs also show some unique functions and morphological features that contribute to our understanding of the structure of natural language. The description of the inflectional and derivational properties is presented proceeding in the direction from form to function, showing regular and compositional patterns and then listing idiosyncratic or lexicalized expressions. The thesis contributes to our understanding of the dialectological relation of Zihuateutla to other languages in the Northern branch for which there is documentation and forms the basis of a linguistic record for typological studies and future generations.
Transparent transducers and fast electronics for next-generation ultrasound and photoacoustic imaging
Creators: Kashani Ilkhechi, Afshin
Publisher: name: University of Alberta Library
Year: 2022

Most ultrasound transducers are opaque. Transparent transducers could lead to novel applications, including combined optical and ultrasound imaging, photoacoustic imaging and other multi-modality systems. This thesis introduces transparent capacitive micromachined ultrasound transducers and demonstrates their use for some of these novel applications. Our long-term objective is to develop 2D row-column arrays for 3D ultrasound, photoacoustic, and optical imaging. The achievement of this long-term objective requires stepwise innovation. We first demonstrate 1D array transparent CMUTs, then overcome optical and electrical material property challenges to fabricate the first-ever transparent linear arrays. We demonstrate these arrays for photoacoustic imaging and combined ultrasound and optical imaging. We additionally take steps toward mitigation of dielectric charging problems in these CMUTs using novel thin-film processes. As a step towards 3D \& 4D imaging with row-column arrays, we first design and fabricate needed fast bias-switching electronics and demonstrate their use with non-transparent row-column arrays. Finally, we outline a roadmap for achieving transparent 2D arrays and postulate their future utility for next-generation 3D multi-modal imaging.

description: Trust management systems often use registries to authenticate data, or form trust decisions. Examples are revocation registries and trust status lists. By introducing distributed ledgers (DLs), it is also possible to create decentralized registries. A verifier then queries a node of the respective ledger, e.g., to retrieve trust status information during the verification of a credential. While this ensures trustworthy information, the process requires the verifier to be online and the ledger node available. Additionally, the connection from the verifier to the registry poses a privacy issue, as it leaks information about the user's behavior. In this paper, we resolve these issues by extending existing ledger APIs to support results that are trustworthy even in an offline setting. We do this by introducing attestations of the ledger's state, issued by ledger nodes, aggregatable into a collective attestation by all nodes. This attestation enables a user to prove the provenance of DL-based data to an offline verifier. Our approach is generic. So once deployed it serves as a basis for any use case with an offline verifier. We also provide an implementation for the Ethereum stack and evaluate it, demonstrating the practicability of our approach.

A General Route to meta-(Arylsulfanyl) and meta-(Alkylsulfanyl) Substituted Phenols and Synthetic Studies on Sorbicillactones A and B
Creators: Do, Nhan Van Thanh
Publisher: name: University of Alberta Library
Year: 2022

Chapter 1 describes a general route for making meta-(arylsulfanyl) and meta-(alkylsulfanyl) phenols using DBU assisted aromatization developed in this laboratory. Thismethod is general and enables the construction of the C-S bond without using high temperatures or transition metal catalyst. The method involves O-tosylation of cyclohexane-1,3-dione,addition-elimination of a thiolate and bromination at C-2 of the resulting 3-arylsulfanyl- or 3-alkylsulfanylcyclohex-2-en-1-one. Finally, treatment with DBU gives the 3-arylsulfanyl- or 3-alkylsulfanylphenol.Chapter 2 describes synthetic studies towards the total synthesis of sorbicillactones A and B. Several different approaches were explored to construct the challenging amide quaternary center in the 5-membered lactone ring. During these studies an intramolecular Michael addition was discovered. This key transformation allowed the construction of the carbocyclic core of sorbicillactone A and B in five steps with the correct stereochemistry at all of the stereogeniccenters, thus opening the door for the further transformations needed to reach the natural products.
Image processing-based techniques for process parameter characterization in Plasma Transferred Arc Additive Manufacturing (PTA-AM) process
Creators: Gajbhiye, Raviraj
Publisher: name: University of Alberta Library
Year: 2022

The plasma transferred arc additive manufacturing (PTA-AM) process is a recently established additive manufacturing (AM) technique for manufacturing large parts for the resource industries. In the PTA-AM process, the build quality of the 3D part is governed by various processing parameters, including but not limited to plasma arc current, stand-off distance (SOD) and powder flow rate. The PTA-AM is challenging for in-process monitoring due to the complex interaction among the plasma arc, powder stream and substrate. Any instability in these processing parameters affects the overall build quality of the component, inducing non-conformance to geometrical properties. In the AM field, various high-speed imaging techniques are used to investigate the correlation between the processing parameter variation contributing to quality fluctuations of the final 3D product. This thesis presents the in-situ image processing methodologies to quantify and analyze the process aspects of the emergent PTA-AM system. Firstly, the single-track multi-layer bead deposition experiments of WC-reinforced NiCrBSi composites are carried out on a PTA-AM system and recorded with a high-speed camera. The optimized SOD has been determined from image analysis, contributing to the uniform deposition with quality deviation. The image analyzed SOD is validated with the experimentally determined SOD. This information is also used to evaluate the impact of powder variation on bead layer height. Secondly, the proposed in-situ image processing technique has been employed to describe the relationship between powder stream distribution and build geometry variation. In addition, the effect of plasma arc current on bead layer geometry (height and width) is also investigated. The Analysis of variance and t-tests has checked the significance of build quality dependence on powder and plasma arc variation. It is well-known that the powder flow behaviour (the particle trajectories and velocities) under the plasma arc region is a complex but crucial physical phenomenon that affects the geometric dimensions and the bead deposition characteristics in PTA-AM. Therefore, we proposed another image processing methodology to investigate the powder stream behaviour under the influence of the plasma arc region. In the findings, variation in trajectories and impact velocities of individual powder particles due to plasma arc has been observed. Using the single-particle trajectory model, we validated that the results are within the theoretical range. Later, based on calculated impact velocities of powder particles, the parametric study was conducted to predict the spreading and solidification of molten powder particles on the substrate. Using dimensionless numbers, the parametric effect of hydrodynamic forces (Weber and Reynolds number) and thermophysical forces (Stefan and Peclet number) on the impinging melted powder particles is also studied.

The Plausibility of Iron-Sulfur Peptides on the Early Earth
Creators: Hu, Yin Juan
Publisher: name: University of Alberta Library
Year: 2022

Iron-sulfur clusters are recognized widely as ancient cofactors that are proposed to have impacted the prebiotic chemistry that led to life. Previous work done by our lab has shown that iron-sulfur clusters could be synthesized prebiotically on cysteine containing tripeptides, but it remains unclear if such complexes could survive under the environmental conditions of the early Earth.

In this thesis, I investigated the stability of iron-sulfur peptides under prebiotically plausible environments. Seven different peptides with various sequences and lengths were used to synthesize iron-sulfur clusters, and these iron-sulfur peptides were tested under different chemical conditions. The results suggested that the types of iron-sulfur clusters formed are dependent on environmental conditions and the peptidyl ligands. Glutathione coordinated iron-sulfur clusters were the most stable among all conditions. The duplication of the tripeptide, i.e., a hexapeptide, would make the corresponding iron-sulfur clusters more stable. This demonstrated the possibility that modern iron-sulfur proteins could have emerged from short peptides that coordinated iron-sulfur clusters from the beginning, and thereby facilitated the emergence of primordial metabolic pathways that then give rise to the life.

description: Public key infrastructure (PKI) is a certificate-based technology that helps in authenticating systems identities. HTTPS/TLS relies mainly on PKI to minimize fraud over the Internet. Nowadays, websites utilize CDNs to improve user experience, performance, and resilience against cyber attacks. However, combining HTTPS/TLS with CDNs has raised new security challenges. In any PKI system, keeping private keys private is of utmost importance. However, it has become the norm for CDN-powered websites to violate that fundamental assumption. Several solutions have been proposed to make HTTPS CDN-friendly. However, protection of private keys from the very instance of generation; and how they can be made secure against exposure by malicious (CDN) administrators and malware remain unexplored. We utilize trusted execution environments to protect private keys by never exposing them to human operators or untrusted software. We design Blindfold to protect private keys in HTTPS/TLS infrastructures, including CAs, website on-premise servers, and CDNs. We implemented a prototype to assess Blindfold's performance and performed several experiments on both the micro and macro levels. We found that Blindfold slightly outperforms SoftHSM in key generation by 1% while lagging by 0.01% for certificate issuance operations.

Design Changes to a Laser-Plasma Simulation Code to Permit Twisted Light Studies
Creators: Armstrong, Blaine
Publisher: name: University of Alberta Library
Year: 2022

Schemes to implement laser bandwidth wide enough to mitigate laser-plasma instabilities will be both intrusive and expensive. As an alternate approach, work is presented

that investigates the mitigating effects of spatial, rather than temporal, laser beam

conditioning on cross-beam energy transfer (CBET) [I.V. Igumenshchev et al., Phys.

Plasmas 19, 056314 (2012)]. Such conditioning might be generated by phase plates

alone and could therefore be implemented more easily. We have quantified the energy exchange occurring between crossing laser beams that possess orbital angular

momentum (OAM) as the amount of OAM exchange between the beams is varied [cf.

e.g., M. Padgett et al., Physics Today 57, 35 (2004)]. This work enables studies to

be performed in 3-D using the non-paraxial wave-based LPSE simulation code [J.F.

Myatt et al., J. Comp. Phys 399, 108916 (2019)]. It required significant modifications to the code to allow for the beams with OAM. The modifications required

changes to the boundary conditions and the total field scattered field (TF-SF) to be

implemented successfully

Comparison of Canadian and U.S. Standard Provisions for Slender Masonry Walls
Creators: Bilotta, Miguelangel Jose
Publisher: name: University of Alberta Library
Year: 2022

Slender, masonry loadbearing walls made with concrete blocks are one of the most frequently used masonry structural systems in North America. They are commonly found in commercial and industrial single-storey construction, such as warehouses, and in school gymnasiums, auditoriums, and retail buildings.

Tall, masonry loadbearing walls subjected to out-of-plane (OOP) loads are often governed by flexure, as the shear demands are small compared to the flexural moments they experience.  Due to their slenderness, these walls are very susceptible to second-order effects, which translate into additional moment demands caused by the presence of axial loads and the wall deflections. Research has shown that to develop rational design procedures and achieve safe and economical design, an accurate estimation of second-order effects is required.

Leading provisions in masonry design in North America, such as the ones in the U.S. and Canada, have similarities and differences that warrant investigation and require an assessment to achieve a unified design method.

This research has several goals: (1) to compare the current strength design and second-order effects provisions for OOP loadbearing masonry walls from North American standards (CSA S304-14 , TMS 402-16 ), with an emphasis on the provisions related with moment amplifications due to second-order moments; (2) to evaluate the influence of different parameters such as reinforcement ratio, slenderness ratio, compressive strength (f_m^') and axial loading, in the flexural rigidity and effective stiffness; (3) to compare the design provisions with numerical models developed using the finite element method; and (4) to conduct regression analyses using a data set developed using the numerical model and proposed expressions for effective stiffness suitable for code inclusion.

Overall, it is expected that this research will identify the key differences in current design standards and lead to recommendations for further harmonization between the US and Canadian codes.
Peatlands Reduce Fire Severity and Promote Fire Refugia in Boreal Forests
Creators: Kuntzemann, Christine E
Publisher: name: University of Alberta Library
Year: 2022

In the boreal biome of North America, large wildfires usually leave behind residual patches of unburned vegetation, termed refugia, which can strongly affect post-fire ecosystem processes. While topographic complexity is a major driver of fire refugia in mountainous terrain, refugia and fire severity (the ecological impacts of fire) in boreal landscapes are more likely driven by bottom-up controls affecting the extent and type of fuels. In this study, I investigate the role of hydrological (e.g., peatlands), ecological, and topographic heterogeneity on fire severity and the presence of fire refugia under different spatial and temporal climate moisture conditions in the Alberta boreal region over a 33-year (1985-2018) period. Fire severity was measured using the Relativized Burn Ratio (RBR). Generalized linear models were used to examine relationships of fire severity and probability of refugia as a function of bottom-up (vegetation, topography, site moisture, ecosystem) and top-down (normal and annual climatic moisture) controls. I then developed predictive maps of refugia probability and fire severity under normal and inter-annual climatic moisture conditions. I found that peatlands, stratified as bogs and fens, burned at lower severities and exhibited a higher probability of refugia than uplands, with vegetation (fuel) presenting a stronger control on fire than climate, topography, site moisture, or ecosystem type. In general, locations with wetter regional (normal) climatic moisture, a proxy for fuel amount, experienced increased fire severity and refugia probabilities when surrounded by more peatlands. While the amount of bogs affected both fire severity and refugia at intermediate scales (900-m area), fens affected fire severity most strongly when at a landscape scale (3000-m area) and refugia when at a local-scale (120-m area). Bogs decreased fire severity in adjacent uplands and peatlands under all regional and annual climatic moisture conditions but did not affect refugia probability in uplands. Fens reduced fire severity in adjacent uplands under all conditions and had varying effects on adjacent peatlands depending on moisture availability. Fens also increased refugia probability in adjacent uplands under all conditions, as well as in adjacent peatlands under all regional climatic moisture conditions. Areas of hydrologically-connected peatlands, particularly fens, may be capable of slowing future vegetation transitions, stemming from climate-driven increases to fire severity and post-disturbance moisture stress, in neighboring forests.
