description: We present high angular resolution observations (0.5"x0.3") carried out with the Submillimeter Array (SMA) toward the AFGL2591 high-mass star forming region. Our SMA images reveal a clear chemical segregation within the AFGL2591 VLA 3 hot core, where different molecular species (Type I, II and III) appear distributed in three concentric shells. This is the first time that such a chemical segregation is ever reported at linear scales <3000 AU within a hot core. While Type I species (H2S and 13CS) peak at the AFGL2591 VLA 3 protostar, Type II molecules (HC3N, OCS, SO and SO2) show a double-peaked structure circumventing the continuum peak. Type III species, represented by CH3OH, form a ring-like structure surrounding the continuum emission. The excitation temperatures of SO2, HC3N and CH3OH (185+-11 K, 150+-20 K and 124+-12 K, respectively) show a temperature gradient within the AFGL2591 VLA 3 envelope, consistent with previous observations and modeling of the source. By combining the H2S, SO2 and CH3OH images, representative of the three concentric shells, we find that the global kinematics of the molecular gas follow Keplerian-like rotation around a 40 Mo-star. The chemical segregation observed toward AFGL2591 VLA 3 is explained by the combination of molecular UV photo-dissociation and a high-temperature (~1000 K) gas-phase chemistry within the low extinction innermost region in the AFGL2591 VLA 3 hot core.

description: This article is devoted to computing the lower and upper bounds of the Laplace eigenvalue problem. By using the special nonconforming finite elements, i.e., enriched Crouzeix-Raviart element and extension $Q_1^{\rm rot}$, we get the lower bound of the eigenvalue. Additionally, we also use conforming finite elements to do the postprocessing to get the upper bound of the eigenvalue. The postprocessing method need only to solve the corresponding source problems and a small eigenvalue problem if higher order postprocessing method is implemented. Thus, we can obtain the lower and upper bounds of the eigenvalues simultaneously by solving eigenvalue problem only once. Some numerical results are also presented to validate our theoretical analysis.

description: Property boundaries in Alberta that are defined by rivers are subject to the doctrine of accretion. A review of the history and development of this doctrine reveals that it accommodates all types of river channel change, including episodic movement, and that it is the overall progress of the change rather than the moment to moment process that should be considered when addressing whether an event is accretionary or avulsive. A behavioural model developed here for wandering gravel-bed rivers in southern Alberta indicates that change to these rivers is largely episodic and is mainly due to non-overbank peak seasonal flows rather than floods, but that rapid change can occur in response to certain events. Application of the behavioural model and the interpretation of the doctrine of accretion developed here to the 2000 Robertson v Wallace court case supports the judge’s rulings in all three disputed reaches.

description: Foreland basins form and fill in response to convergent-margin tectonism; as such, in this thesis the detrital zircon and stratigraphic record of the Western Interior basin (Montana-Alberta) are studied in order to deduce the geological history the North American Cordillera. Detrital zircon data presented here are generally characterized by either: (1) diverse detrital zircon spectra that reflect recycling from pre-foreland sedimentary strata; and (2) detrital zircon spectra dominated by Mesozoic populations, which indicate provenance dominated by the Cordilleran magmatic arc. The spatial and temporal variation amongst populations from across the basin suggest that the orogen evolved through cyclic pulses of tectonism, and that intrabasinal topography and wedge-top evolution significantly influenced development of sediment-routing systems across the basin. Pulses of arc activity are linked to increased subsidence in the basin, which are commonly reflected in stacking patterns of Early Cretaceous fluvial strata.

description: We study experimentally and theoretically a dense ensemble of negatively charged nitrogen-vacancy centers in diamond coupled to a high $Q$ superconducting coplanar waveguide cavity mode at low temperature. The nitrogen-vacancy centers are modeled as effective spin one defects with inhomogeneous frequency distribution. For a large enough ensemble the effective magnetic coupling of the collective spin dominates the mode losses and inhomogeneous broadening of the ensemble and the system exhibits well resolved normal mode splitting in probe transmission spectra. We use several theoretical approaches to model the probe spectra and the number and frequency distribution of the spins. This analysis reveals an only slowly temperature dependent q-Gaussian energy distribution of the defects with a yet unexplained decrease of effectively coupled spins at very low temperatures below $\unit{100}{\milli\kelvin}$. Based on the system parameters we predict the possibility to implement an extremely stable maser by adding an external pump to the system.

description: Tone mapping algorithms are used to adapt captured wide dynamic range (WDR) scenes to the limited dynamic range of available display devices. In this thesis, a real-time hardware implementation of an exponent-based tone mapping algorithm is presented. An automatic parameter selector was designed for this algorithm in order to achieve good tone-mapped images without manual reconfiguration of the tone mapping algorithm. Both algorithms were implemented in Verilog and synthesized for an FPGA device. The hardware architecture employed a combination of parallelism and system pipelining so as to achieve a high performance in power consumption, hardware resources usage and processing speed. In addition, modifications to the tone mapping algorithm were implemented so as to increase the image and video quality of the tone-mapped image frames. Objective image quality assessment shows that the improved tone mapping algorithm attains higher image quality scores than the original tone mapping operator.

description: We have used injection locking to multiply the repetition rate of a passively mode-locked femtosecond fiber laser from 40 MHz to 1 GHz while preserving optical phase coherence between the master laser and the slave output. The system is implemented almost completely in fiber and incorporates gain and passive saturable absorption. The slave repetition rate is set to a rational harmonic of the master repetition rate, inducing pulse formation at the least common multiple of the master and slave repetition rates.

description: Introduction:
 Ischaemic heart disease (IHD) is on the rise among adults under 40-years. Radionuclide myocardial perfusion scintigraphy (MPS) can provide imaging information to diagnose, evaluate and risk stratify IHD. Nevertheless, local data are limited on the usage of this technique in identifying IHD among young adult patients. Our objectives were to determine important clinical characteristics of these patients who underwent MPS for IHD detection and highlight their scintigraphy findings. Methodology:
 A case-series and pictorial review of adults aged 30-40 years old (n=34) who had two-day protocol MPS using 99mTechnetium-tetrofosmin done between January and December 2019. Scan acquisition being performed as per standard departmental protocol. Reversible perfusion defect signified ischaemia whereas irreversible perfusion defect implied infarction. Clinical information and scan findings were compiled and analysed. Results:
 Average age was 36.59 years. Females were predominant (n=19, 55.9%). Majority had ≥2 cardiovascular risk factors (n=22, 64.7%). Small proportion of patients had morbid obesity (n=3, 8.8%) and intermediate risk for pre-test IHD probability (n=12, 35.3%). Imaging findings of MPS included normal perfusion (n=9, 26.5%), artifact (n=1, 2.9%), ischemia (n=23, 67.6%) and infarction (n=1, 2.9%). Mean ejection fraction on stress MPS was 66%. Patients with ≥2 cardiovascular risks and intermediate probability were significantly associated with abnormal MPS findings (p<0.05). Conclusions:
 IHD was observed in 70.5% of adults under 40-years who were referred for MPS. Those who had ≥2 cardiovascular risks and intermediate probability were significantly associated with abnormal MPS findings. Attention should be given during scintigraphy images interpretation and reporting of these particular patients.

The Effects of Giardia duodenalis on the Intestinal Mucus Layer

Year: 2017
Subjects: subject: Biology

description: The intestinal mucus layer is a highly dynamic interface that protects the intestinal epithelium and underlying tissues against noxious stimuli in the external environment. Alterations to the mucus matrix or the mucus-secreting goblet cells can result in impaired barrier function, lending to translocation of luminal antigens and opportunistic pathogens. Giardia duodenalis - a cosmopolitan parasite that colonizes the small intestine – is one of the leading causes of infectious diarrhea and a major contributor to post-infectious functional gastrointestinal disorders. This study reveals a complex interaction at the surface of intestinal epithelial cells, between G. duodenalis and the intestinal mucus layer. Here, we reveal mechanisms whereby G. duodenalis evades and disrupts the first line of host defense, the mucus layer, by degrading mucin-2 (MUC2), depleting mucin stores, and inducing differential gene expression in the small and large intestine. Infection in Muc2-/- mice demonstrated the importance of a functional mucus layer, as mice devoid of intestinal mucus had elevated trophozoite colonization in the small intestine and suffered significant weight loss. Wild-type mice infected with G. duodenalis had a thinner mucus layer and demonstrated differential mucin gene expression, including an increase in Muc2 and de novo expression of Muc5ac in the colon. Human colonic biopsies exposed to G. duodenalis exhibited a reduction of mucus stores. In vitro, G. duodenalis depleted mucins from human LS174T goblet cells and induced elevated expression of MUC2 mRNA. Mucin depletion was dependent on protein kinase C (PKC) and phosphatidylinositol 3-kinase (PI3K) cell-signaling. Overall, the effects of G. duodenalis on the intestinal mucus barrier resulted in impaired barrier function, observed by the translocation of bacterial species into the extra-intestinal organs of infected mice. Importantly, the broad-spectrum cysteine protease inhibitor E64 prevented mucus degradation, mucin depletion, and the increase in MUC2 gene expression. This study demonstrates a critical role for Giardia’s cysteine proteases in pathogenesis, and describes how Giardia’s disruptions of the mucus barrier facilitate bacterial translocation that may contribute to the onset and propagation of disease.

description: Most diurnal primates live in cohesive social groups in which all or most members range in close proximity, but spider monkeys (Ateles) and chimpanzees (Pan) are known for their more fluid association patterns. These species have been traditionally described as living in fission-fusion societies, because they range in subgroups of frequently changing size and composition, in contrast with the more typical cohesive societies. In recent years the concept of fission-fusion dynamics has replaced the dichotomous fluid versus cohesive categorization, as it is now recognized that there is considerable variation in cohesiveness both within and between species. This thesis is a study of the fission-fusion dynamics in spider monkeys to quantify and explain temporal variation in subgroup size, spatial cohesion, and stability. I collected behavioural, ecological, and genetic data from a group of spider monkeys at Runaway Creek Nature Reserve in Belize from January 2008 until September 2013. I found that most subgroups were small (1-3 individuals), contained only adult females, and changed membership every 30-40 minutes. Habitat-wide fruit availability showed a weak relationship with subgroup size, contrary to what I expected, but it did explain some of the variation in subgroup stability. Likewise, degree of relatedness between individuals was not correlated with an association index that measured the likelihood that any two individuals would be in the same subgroup together. This thesis also describes the feeding ecology of the study group, and explores their genetic structure. The latter revealed some unexpected patterns: although traditionally believed to be a male philopatric, female dispersal species, male spider monkeys at Runaway Creek were no more closely related to one another than were females, and both males and females were residents and immigrants. As expected, given the common characterization of spider monkey males as experiencing low levels of within-group competition for females, paternity analysis revealed no reproductive skew, with all males siring offspring. Further analysis is needed to identify and understand the variables that are affecting the temporal changes in subgroup size, spatial cohesion, and stability of this group. However, this study makes an important contribution to this much larger question.
Myoferlin-dependent regulation of receptor tie-2 : characterization of a novel endothelial-specific anti-angiogenesis target
Creators: name: Yu, Carol
Publisher: name: University of British Columbia
Year: 2010

description: Heart disease and cancer are the two leading causes of death worldwide. In heart disease, reperfusion of an ischemic myocardium through increased angiogenesis, or the growth of new blood vessels, is considered the ‘holy grail’ of future therapies. In contrast, inhibiting tumour growth by decreasing angiogenesis through anti-angiogenic therapies is increasingly used in cancer patients, although the therapeutic effect is only partial. Hence, a better comprehension of angiogenesis is clearly warranted. While a plethora of literature suggests that the vascular endothelial growth factor (VEGF) and angiopoietins systems are the most potent endogenous regulators of angiogenesis, an increasing number of recent studies also show that their net angiogenic effects are mostly dictated by membrane expression of their main receptors, VEGFR-2 and tie-2, respectively. Recently, endothelial cells (ECs) were unexpectedly found to express myoferlin, a muscle protein [1] known for its ability to regulate plasma membrane integrity [2]. Moreover, myoferlin was found to be involved in the regulation of VEGFR-2 expression in ECs [3]. In this work, we report that disruption of myoferlin by gene-silencing causes decreased tie-2 expression in cultured ECs. However, myoferlin disruption does not affect the transcriptional levels of tie-2 in cultured ECs. Separation of caveolae/lipid rafts from cytosol in ECs shows presence of myoferlin and tie-2 in caveolae/lipid rafts, suggesting co-localization of the two proteins to form a large signaling complex at caveoli, which are known platforms for clustering of signaling complexes. Moreover, myoferlin is present in a cancer cell model (Lewis Lung Carcinoma) and myoferlin disruption causes decreased cell proliferation, further exploring the involvement of this membrane protein in a completely different cell system. The current work identifies potential pharmacological targets for the regulation of the tie-2 system and since tie-2 expression is almost exclusively found in ECs, this work initiates the characterization of an EC-specific target that could be further exploited to modulate angiogenic responses in an in vivo model.

description: Defect modes are investigated in a band gap of an electrically tunable one-dimensional photonic crystal infiltrated with a twisted-nematic liquid crystal (1D PC/TN). Their frequency shift and interference under applied voltage are studied both experimentally and theoretically. We deal with the case where the defect layer thickness is much larger than the wavelength (Mauguin condition). It is shown theoretically that the defect modes could have a complex structure with the elliptic polarization. Two series of polarized modes interact with each other and exhibit an avoided crossing phenomenon in the case of opposite parity.

Molecular and cellular studies of Drosophila neuroserpin Spn4A and its polymer-forming mutants
Creators: name: Lai, Christine Chieh-Lin
Publisher: name: University of British Columbia
Year: 2010

description: Serpins (Serine Protease Inhibitors) are expressed by most organisms and perform a variety of functions. Most serpins inhibit proteases by undergoing a unique conformational change. They are clinically relevant in two ways. First, introduction of single amino acid point mutations transforms the serpins’ labile conformations into pathogenic, inactive polymers causing “serpinopathies”. In particular, human neuroserpin is a brain-specific serpin that, when mutated, causes a debilitating early onset dementia through unknown cellular pathways. Second, serpins are currently under investigation as therapeutic inhibitors of proprotein convertases (PCs). PCs are associated with some bacterial and viral infections as well as cancer. However, no comprehensive investigation into the cellular effects of PC inhibitor expression in mammalian cells has been performed. This thesis details the use of the Drosophila serpin, Spn4A, to address the cellular pathways mediated by serpin polymers or PC inhibition. Spn4A is a neuron-specific, secretory pathway serpin that inhibits Drosophila or human PCs. We hypothesized that Spn4A mutants, encoding homologous disease-causing mutations in human neuroserpin, would form pathogenic polymers and represent an ideal candidate for generating a cell-based and transgenic Drosophila serpinopathy model. Further, we hypothesized that we could evaluate the cellular response to PC inhibition and polymer accumulation by transcriptome profiling of H4 human neuroglioma cells expressing Spn4A wild-type and mutants. We established an expression system using Spn4A and its mutants in H4s. Subsequently, we used microarray analysis to simultaneously address how serpin polymers may induce cytotoxicity as well as the effects of proprotein processing inhibition in neuroglioma cells. We demonstrated that Spn4A mutants formed polymers, were retained in the endoplasmic reticulum, and lacked inhibitory function, but induced few changes on the transcriptome (under 20 genes differentially regulated). To this end, we have developed transgenic Drosophila overexpressing Spn4A variants to further investigate the biological impact of Spn4A mutants. Next, we analyzed the response to the PC inhibitor, Spn4A, and found marked changes in genes related to malignancy. Our genome-wide gene expression studies have provided novel insights into cellular changes in response to polymeric or PC-inhibiting serpins, and establish the foundation for future functional studies.

description: The law in Canada is at times very complicated to apply and is often partially regulating--meaning that in its application the law fails to dictate a single legally viable outcome in a legal case. As a result of this complexity judges who apply the law must often choose one from among multiple legally viable outcomes in the cases they decide. On the basis of such claims I infer that judges must be viewed as having the power and the duty to exercise discretionary authority in their decision making. The central questions addressed in my thesis are these: (i) need there be constraints on the exercise of this discretionary authority? (I argue, of course, that there is such a need); and (ii) what is the nature and grounding of these constraints? My main argument is that the more traditional ways of explaining the status of the constraints are at least incomplete and provide reasons to believe that there is a particular set of second-order moral constraints which must be taken as guiding judicial discretion in partially regulated cases. I argue that these second-order moral constraints are binding on all judges and that our theories of judicial decision making need to acknowledge both the role and the status of these constraints. This main argument is developed with the support of a series of foundational claims which are intended to highlight the need for consistency and predictability in judges’ interpretation and application of the law. These foundational claims are intended to demonstrate the fact that constraints on judicial discretion are necessary in order for judicial decision making to be (and to be considered to be) legitimate. I argue that, because of the complexity and partially regulating nature of the law, it is not realistic to insist on consistency in judicial outcomes, but that a deeper-level consistency in judicial reasoning in accordance with second-order canons of responsible moral reasoning is a realizable demand. Consistency is itself a useful and important factor to take into account when evaluating judges’ decisions since only if such decisions comply with these canons can the decisions be viewed as being legitimate: I point out that consistency in judicial decisions is desirable only if it is consistency of legitimate judicial decisions. By exploring this requirement in more detail we deepen our understanding of what judicial reasoning and decision making requires. I argue finally that judges are morally obligated to follow the canons not because they are professionals, nor because they are judges, but because they are moral agents.

description: An entanglement-generating protocol is described for two qubits coupled to a cavity field in the bad-cavity limit. By measuring the amplitude of a field transmitted through the cavity, an entangled spin-singlet state can be established probabilistically. Both fundamental limitations and practical measurement schemes are discussed, and the influence of dissipative processes and inhomogeneities in the qubits are analyzed. The measurement-based protocol provides criteria for selecting states with an infidelity scaling linearly with the qubit-decoherence rate.

description: Traditionally, much of the published literature about addictions counselling has focused on research supporting evidence-based approaches to treatment, establishing and maintaining best practices to achieve and maintain recovery, and prescribing how therapeutic interventions ought to be delivered. Little attention has been directed toward translating recovery into something that is done in the day-to-day work of counsellors within addictions treatment institutions, nor how this doing is socially organized more broadly. In this inquiry I used D. E. Smith’s institutional ethnography to call attention to the social organization of frontline recovery work within a residential treatment Centre. The everyday work of addictions counsellors was the focus of my ethnographic interest, and connecting this work into larger social and institutional policies and procedures was the focus of my analysis. First, I explored the work of admissions counselling that takes place prior to a client entering the treatment program. Next, I focused my analysis on how the counsellors facilitate the treatment program, and identified disjunctures between the embodied experiences of frontline practitioners and enforced institutional counselling discourses and requirements. Finally, I explicated the process of producing institutionally acceptable accounts of the recovery work that has taken place. I looked at the invisible addictions counselling work being done at the Centre to accomplish the ends of recovery with clients, and I identified institutional practices that obscured this work from view. I concluded with an enhanced understanding of recovery work as something that is done by counsellors, with clients, within the context of addictions treatment. Implications for counselling practice and possible future research are discussed, as the findings expand what can be seen and known from the frontlines of practice.
Automatically Characterizing Logging Usage: An Application of Anti-Unification

subject: anti-unification

description: Logging has been a common practice to record the runtime behaviour of a software system, typically performed by inserting log statements in its source code. While several frameworks have been specifically created to help developers perform logging tasks, these do not provide guidance on where the log statements should be located in the source code. Thus, developers usually rely on their common sense to decide where to log. If logging is done properly, it can provide valuable information for software development and maintenance; if it is done poorly, system performance can degrade and maintenance can be made more difficult. Few studies have been conducted to characterize logging usage in real-world applications. This work tries to address the problem of where to log by proposing an automated approach that characterizes the location of log statements through the approximation of an anti-unification approach (specifically, higher-order anti-unification modulo theories) and a hierarchical clustering technique to construct a set of anti-unifiers, each describing the commonalities and differences between source code fragments that embody log statements. This approach has been reified in a prototype tool, called ELUS, that greedily identifies the best structural correspondences with respect to the highest similarity and some constraints. An empirical study was conducted by applying the tool on the source code of four open source systems and manually examining the generated anti-unifiers. The analysis resulted in five main categories of anti-unifiers in the logging usage. Two empirical evaluations were conducted in this work: (1) an experiment was conducted to evaluate the effectiveness of the proposed approach through the application of its supporting tool on a test suite; and (2) an experiment was performed to evaluate the quality of the anti-unifiers in describing the location of log statements in source code.

description: Introduction: Excessive radiation dose may be inadvertently delivered by radiology personnel during radiological procedures. Objectives: This is an action research aimed to improve radiological personnel's performance and awareness on proper fluoroscopy technique and radiation dose delivery through the establishment of multimodal transformation strategies. Methodology: The study involved three phases: Phase I (Pre-intervention) involved a mixed-method analysis to determine the prevalence of excessive radiation exposure during fluoroscopy and to assess the level of knowledge, awareness and practice among radiological personnel on proper fluoroscopy technique. The qualitative part involved a single interview session with 12 personnel on their opinion and regular practice with regards to fluoroscopy procedure. Results were thematically analyzed. The quantitative part involved distribution of questionnaires assessing the knowledge, awareness and practice to 33 staff; Phase II (Intervention) were carried out through regular monitoring and teaching sessions, followed by Phase III (Post-intervention) where re- assessment of knowledge, awareness and practice were performed. Results: We found that the prevalence of excessive radiation dose delivery was 23% prior to intervention, contributed by the lack of knowledge and training. Data analysis following our interventional program showed improvement in clinical radiation dose delivery (10% vs. 23%), and improvement in the scores for the knowledge (p<0.001), awareness (p=0.025) and practice (p<0.001) during fluoroscopy procedure. Discussion / Conclusion: Our findings highlight the importance of preserving the safety of medical imaging in providing optimal service delivery. We would recommend our interventional program to be replicated at other healthcare centres to allow better patient outcome.

Subjects: Vildagliptin; type 2 diabetes mellitus (T2DM);

description: Introduction: In Queen Elizabeth II Hospital (QE2), Vildagliptin is often used as the second or third line oral hypoglycemic agent (OHA) in the management of type 2 diabetes mellitus (T2DM). Malaysian Clinical Practice Guidelines (CPG) for the Management of T2DM states that dipeptidyl peptidase-4 inhibitor (DPP4-I) such as Vildagliptin could reduce HbA1c by 0.5% - 0.8%. [1] This study described real-life use of Vildagliptin and reviewed the change in HbA1c post-Vildagliptin prescription in T2DM management in QE2. Methods: From January 2019 till December 2019, a retrospective case note review was carried out in QE2. Irretrievable case notes and patients with poor medication compliance were excluded. Results: As a whole, HbA1c measurements were improved significantly by a mean of -1.44% (SD±1.9) post-Vildagliptin prescription (f values: 0.01 – 0.017). The results suggested a reduction of HbA1c measurements postVildagliptin prescription in these groups of patients. Conclusion: The significance of the findings in this study was limited by the small sample size. Our findings implied that: ✓ The efficacy of Vildagliptin in HbA1c reduction in real-life practice was in-line with that stated in the Malaysian CPG for the management of T2DM. [1] ✓ Vildagliptin at renal-adjusted dose could reduce HbA1c effectively. ✓ Use of Vildagliptin with insulin could improve HbA1c at a greater extend compared to its use with other OHA. ✓ Most races of T2DM patients in QE2, Sabah responded well to Vildagliptin treatment in terms of HbA1c reduction. Nevertheless, a larger study is warranted to address the limitation.

Thinking outside the box: Exploring creativity and social skills in children with Attention-Deficit/Hyperactivity Disorder
Creators: name: Taylor, Meghan
Publisher: name: Graduate Studies

Subjects: subject: Psychology--Developmental
subject: ADHD
subject: Creativity
subject: Social Skills

description: The current study investigated the constructs of creativity and social skills in children between the ages of 8-11 years who had been previously diagnosed with Attention-Deficit/Hyperactivity Disorder (ADHD). Information on the construct of social skills was attained via self-report measures completed by both the participating child and his or her parents. Creativity was assessed with a measure of figural creativity. Children rated their social skills as significantly higher than did their parents; parents rated their children within the low average range, while the children rated themselves within the average range. It was also determined that the children’s figural creativity fell within the average range in comparison to the normative data; however, contrary to the hypotheses, there was no relationship found between the constructs of social skills and creativity. These findings suggest that additional research should focus on creativity as a possible strength in children with ADHD, and its relationship with social skills should be investigated further with a larger sample.

description: Deep learning (DL)-based methods have demonstrated remarkable achievements in addressing orthogonal frequency division multiplexing (OFDM) channel estimation challenges. However, existing DL-based methods mainly rely on separate real and imaginary inputs while ignoring the inherent correlation between the two streams, such as amplitude and phase information that are fundamental in communication signal processing. This paper proposes AE-DENet, a novel autoencoder(AE)-based data enhancement network to improve the performance of existing DL-based channel estimation methods. AE-DENet focuses on enriching the classic least square (LS) estimation input commonly used in DL-based methods by employing a learning-based data enhancement method, which extracts interaction features from the real and imaginary components and fuses them with the original real/imaginary streams to generate an enhanced input for better channel inference. Experimental findings in terms of the mean square error (MSE) results demonstrate that the proposed method enhances the performance of all state-of-the-art DL-based channel estimators with negligible added complexity. Furthermore, the proposed approach is shown to be robust to channel variations and high user mobility.
