description: The objectives of this study were to isolate E. coli from stormwater, detect virulence genes (VGs) associated with intestinal (InPEC) and extraintestinal pathogenic E. coli (ExPEC), and evaluate antimicrobial resistance. In addition, the proportion of tetracycline-resistance E. coli in stormwater and their multidrug resistance (MDR) was determined. Presumptive E. coli (n=770) were isolated from water samples (n=83) collected weekly between August to September from stormwater retention ponds in Alberta, Canada. VGs associated with InPEC (eaeA, ehxA, bfpA, aggR, ipaH, STa, and LT) and ExPEC (sfa/foc, fimH, papC, fyuA, iutA, iroN, cnf1, and hlyA) were assessed using multiplex and single PCR. Moreover, tetracycline-resistant E. coli were isolated using tetracycline-embedded (1µg/ml – 4µg/ml) agar plates via replica plating. Subsequently, the clonal relatedness of E. coli isolates was determined via repetitive extragenic palindromic sequence PCR. Then, antimicrobial susceptibility testing was performed using the Sensititre CMV4AGNF plates. Among the 761 confirmed E. coli isolates, 17 (2.2%) carried the adhesion VG, eaeA. In addition, 4 (0.53%), 719 (95%), and 1 (0.13%) were positive for ExPEC fimbrial/pili adhesin VGs, sfa/foc, fimH, and papC, respectively. Furthermore, iron acquisition genes were also detected, including fyuA (13%), iutA (0.80%), and iroN (13%), with the proportion of iroN and iutA positive isolates significantly different (P < 0.001 and P < 0.0018) between two sites. The toxin gene, cnf1 (0.13%), was also detected. Among the isolates carrying the eaeA gene and >3 ExPEC VGs, 24% were resistant to antimicrobials, including tetracycline, ampicillin, and streptomycin. Finally, the proportion of tetracycline-resistant E. coli in stormwater samples (n=83) was 44%. Of these, 47% and 70% of unique isolates from Site 1 and Site 2 were resistant to more than two antimicrobials, with most isolates also resistant to streptomycin (33%-50%) and ampicillin (30%-45%). Multiple antimicrobial resistance (MAR) index patterns indicated MDR isolates may originate from high-risk sources in both sites.This study provided an insight into the microbial quality of stormwater concerning the prevalence of antibiotic-resistant and VG harbouring E. coli. These results may help develop practical microbial management strategies imperative to prevent potential public health risks associated with stormwater reuse for irrigation of public spaces.

description: Background: Contracture and spasticity are common impairments in people with cerebral palsy (CP). Despite a shift from passive to more active therapies, effects of activity-based training on contracture and spasticity are still unclear. Several objective measures have previously been proposed to differentiate contracture and spasticity. Their utility for use with an instrumented, portable device has yet to be established.Objectives: Aim 1 was to determine the effect of activity-based training on lower extremity contracture and spasticity in people with CP. Aim 2 was to determine the utility of various contracture and spasticity outcome measures for use in a clinical trial of lower extremity exercise in young children with CP.Methods: Project 1 was a systematic review. Two independent reviewers screened studies for eligibility. Studies were categorized by intervention type, methodological quality was assessed, and a narrative synthesis was pursued. Project 2 was a case study of a 16-month-old child with hemiplegia who completed 3 months of intensive targeted lower extremity exercise. Passive range of motion-, electromyography-, and torque-based outcome measures were obtained monthly using a portable device and critiqued based on clinical relevance, validity, and reliability.Results: Project 1: 58 articles met all inclusion criteria. Very few studies reported negative outcomes. Strength and gait training programs that improved contracture also improved functional strength and gait parameters. Improvements were mainly in children, with very few changes in adults. Project 2: There were no improvements in any outcome measure in response to the training program. Passive range of motion had low clinical relevance due to poor experimental controls at the time. EMG-based outcome measures were highly variable due to the unreliability of surface EMG and technical issues pertaining to using a portable device in children. Torque-based outcome measures showed lower variability and identified several increasing trends in contracture.Conclusions: Future studies that use instrumented measures are necessary to advance our knowledge regarding activity-based training, which is a viable option for managing contracture and spasticity in people with CP. Future trials that implement activity-based training and use a portable device should use range- and torque-based contracture and spasticity outcome measures.

description: Large-scale deep disposal of CO2 is viewed as a promising tool to curb the increasing streak of anthropogenic carbon emissions. Therefore, a good understanding of the scientific and engineering challenges related to CO2 storage is required to carry out the extensive deployment of CO2 storage. Analytical and semi-analytical approaches provide an easy-to-use tool to verify the success of long-term and large-scale deployment of subsurface CO2 storage. The classical solutions lack significant features that are essential in the interpretation of the spatiotemporal evolution of pressure plume. In this dissertation, obviating the limiting assumptions, I report a set of mathematical models and their solutions.The physical models considered in this thesis include storage-caprock-overburden system, storage sites with existing abandoned wells, and caprock-monitoring aquifer system where caprock has a permeability field with both spatial and temporal variability. The solution methods used in this thesis are semi-analytical in nature where the exact Laplace space solutions are inverted to time domain by using a numerical inversion scheme. The obtained solutions were verified analytically and compared with the classical solutions.The results indicate that the behavior of pressure plume evolution can be a useful tool to safeguard the caprock integrity. The nature of temporal behavior of leakage rates from the storage-caprock interface is investigated and several scaling relations are identified. I also presented benchmark pressure trends to detect the pressure anomaly signaling potential CO2 leakage through storage-caprock interface and through abandoned wells. The results also showed that the average effect of pre-existing natural fractures and/or induced fractures on caprock permeability field can be represented by an intactness ratio, and the usefulness of varying flow capacity in caprocks is found prominent when compared to the classical solutions with uniform permeability fields.The presented solutions and scaling relations will find their usefulness in numerous engineering problems such as CO2 and waste disposal in deep geological formations and geothermal energy extraction. Theories studied in this thesis will also be invoked as benchmark analytical studies in fields where diffusion is of immense interest.

On the Riemann Tensor in Double Field Theory

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Double field theory provides T-duality covariant generalized tensors that are natural extensions of the scalar and Ricci curvatures of Riemannian geometry. We search for a similar extension of the Riemann curvature tensor by developing a geometry based on the generalized metric and the dilaton. We find a duality covariant Riemann tensor whose contractions give the Ricci and scalar curvatures, but that is not fully determined in terms of the physical fields. This suggests that α' corrections to the effective action require α' corrections to T-duality transformations and/or generalized diffeomorphisms. Further evidence to this effect is found by an additional computation that shows that there is no T-duality invariant four-derivative object built from the generalized metric and the dilaton that reduces to the square of the Riemann tensor.

description: Background: While screening tools are available for the early identification of eating disorders, it may not be feasible to employ them in an emergency department (ED). Establishing a risk profile for patients with eating disorders may improve the screening process. The purpose of this study was to identify patterns of presentation in anorexia nervosa (AN) and bulimia nervosa (BN) that may help to detect eating disorders at an earlier and more treatable stage. Methods: We applied a convergent mixed methods research design. The quantitative component involved a retrospective cohort analysis of administrative ED data for patients (n=243) in an eating disorders program (EDC – Eating Disorder Cohort). Two control groups: 1) Control Group 1 (CG1) All-cause ED visit (n=716) and 2) Control Group 2 (CG2) Mental health ED visit (n=679) were included. The qualitative component consisted of semi-structured interviews with patients with eating disorders, parents, and ED residents (n=18).Results: Most patients (68.7%, 95% CI: 66.0-71.2) with eating disorders were discharged from the ED without follow-up being arranged. Comorbidities were recorded as the primary or secondary diagnosis, and patients presented with suicidality more frequently than controls (? = 31.2, p < .001). Patients with eating disorders accessed ED services five times more frequently than controls; x? = 4.98, 95% CI: 4.26-5.70 (CG1: x? = 1.01, 95% CI: 1.00-1.02, CG2: x? = 1.05, 95% CI: 1.03-1.07). The six global themes from the interviews included Assessment, Barriers & Facilitators, Emergency Visit Experience, Emotional Impact, Quality of Care, and COVID-19. Qualitative findings were supported by the quantitative disposition data and International Classification of Diseases 10th revision (ICD-10) codes. Discussion: Despite patients with eating disorders accessing the ED more frequently than control patients, eating disorder diagnoses were not consistently assigned and documented. Our findings highlight the importance of residency education and the consideration of comorbidities and suicide risk when assessing patients to ensure early detection and appropriate referral for care.Conclusion: Providing ED residents with further training and access to screening tools for eating disorders may help to improve detection, mitigate symptom progression, and enhance patient safety and quality of care.

description: Launched on June 11, 2008, the LAT instrument onboard the $Fermi$ Gamma-ray Space Telescope has provided a rare opportunity to study high energy photon emission from gamma-ray bursts. Although the majority of such events (27) have been iden tified by the Fermi LAT Collaboration, four were uncovered by using more sensiti ve statistical techniques (Akerlof et al 2010, Akerlof et al 2011, Zheng et al 2 012). In this paper, we continue our earlier work by finding three more GRBs ass ociated with high energy photon emission, GRB 110709A, 111117A and 120107A. To s ystematize our matched filter approach, a pipeline has been developed to identif y these objects in near real time. GRB 120107A is the first product of this anal ysis procedure. Despite the reduced threshold for identification, the number of GRB events has not increased significantly. This relative dearth of events with low photon number prompted a study of the apparent photon number distribution. W e find an extremely good fit to a simple power-law with an exponent of -1.8 $\pm $ 0.3 for the differential distribution. As might be expected, there is a substa ntial correlation between the number of lower energy photons detected by the GBM and the number observed by the LAT. Thus, high energy photon emission is associ ated with some but not all of the brighter GBM events. Deeper studies of the pro perties of the small population of high energy emitting bursts may eventually yi eld a better understanding of these entire phenomena.

description: It is well established that CaM exhibits a calcium-dependent association with the C-terminal region of high-voltage activated voltage-gated calcium channels. Recent work has shown that low voltage-gated Cav3.1 channels exhibit a constitutive association with CaM at rest that is close enough to support FRET in tsA-201 cells. This thesis examines the distribution of Cav3.1 and CaM that exhibit a dynamic loss of FRET with depolarization in relation to plasma membrane compared to internal structures in tsA-201 and cultured hippocampal neurons. I tested the hypothesis that upon Cav3-mediated calcium influx, a Cav3-CaM cascade is triggered reflecting CaM dissociation from the channel at both the plasma membrane and from internal structures of cells. FRET was used to image interactions between Cav3.1 and CaM occurring within 10 nm of one another in live tsA-201 cells. To aid in visualizing this relationship at an increased resolution, TIRF combined with SRRF super-resolution post processing revealed a large proportion of Cav3.1-CaM colocalization and FRET both internally and at discrete points on the plasma membrane. TIRF-SRRF imaging also revealed extensive internal Cav3.1 labeling organized similarly to the smooth ER. Super-resolution imaging using TIRF-SRRF and dSTORM-TIRF revealed a colocalization of Cav3.1 and the ER calcium leak channel, Sec61, through either co-expression of tagged proteins or immunolabeling. Co-immunoprecipitation experiments confirmed a close relationship between Cav3.1 and Sec61 at resting calcium levels in tsA-201 cell homogenates. The Sec61? isoform was localized with Cav3.1 in the ER and at the plasma membrane but did not affect Cav3.1 channel biophysical properties in whole-cell recordings. dSTORM-TIRF imaging and morphological cluster analysis of Cav3.1, CaM and Sec61? immunolabels in cultured hippocampal neurons confirmed that Cav3.1-CaM, Cav3.1-Sec61?, and CaM-Sec61? showed close and preferential localization. A localization of Cav1.3 or Cav2.2 immunolabels to ER membranes was present but not as extensive as for Cav3.1. Taken together, this work demonstrates a novel expression pattern and association of Cav3.1-CaM with the ER pore protein Sec61, with Cav3.1-CaM FRET detected at the plasma membrane and at internal ER sites.
Quiet Crash Sites: Antun Maračić’s Cro Car Crash Chronicle, after War/hol and Usput spomenici/ Sideroad Monuments and Aernout Mik’s Refraction

description: With the beginning of modernity death has been pushed to the margins of society. Indeed, for many, the only time they are confronted with death outside their immediate circle of friends or family is the chance encounter with the traffic accident, which is by now the most frequent form of public death in Western society. But while we try to deny death by institutionalising it and banning it from the everyday, the crowds who flock to the sites of accidents and violent deaths manifest our undiminished need to know about death.
This essay examines our paradoxical attitude to accident sites, their attraction and repulsion, by looking at three artworks: Antun Maracic's photographic cycles Cro Car Crash Chronicle, after War/hol (2001-2) and Usput spomenici/ Sideroad Monuments (1999-2002) and Aernout Mik's video installation Refraction (2005). Maracic's two photo cycles are compendium works: Cro Car Crash Chronicle consists of a series of black-and-white press photographs of car crashes, and Sideroad Monuments focuses on crosses and memorials which mark the deaths of traffic victims. Mik's Refraction consists of a tripartite installation of a looped silent video of a large-scale traffic accident. In all three works the crash and the crash site are stylised into an aesthetic experience and the gallery becomes a place for the contemplation and acceptance of the fact of death.

Experimental characterization of the viscoelastic behavior of a curing epoxy matrix composite from pre-gelation to full cure
Creators: name: Thorpe, Ryan J.
Publisher: name: University of British Columbia
Year: 2013

description: Process models have been used to predict the flow and stress development during manufacturing of composite structures for over 20 years. To date, these models have been treated separately, and the required material property models (viscosity and modulus) have also been treated separately. The latest breakthrough in process modeling of composite structures is an integrated stress-flow model. However, a consistent viscosity and viscoelastic material model required by the integrated stress-flow model has not been developed. Presented in this thesis is a consistent material model that predicts the viscoelastic liquid and viscoelastic solid behavior of a commercially available thermoset polymer, namely MTM45-1 epoxy. The goal here is to show that a single material model can predict the viscosity and viscoelastic modulus for all temperature, degree of cure and time scales encountered in composite manufacturing. The model was generated by fitting a generalized Maxwell model to test results from both dynamic mechanical analysis and rheological tests. Both resin and prepreg samples were examined. Thermo-rheological complex behavior was captured by applying linear temperature dependence to the un-relaxed modulus. The effect of cure was accounted for by applying a degree of cure dependent shift function. The relaxed modulus was predicted using the cross-link concentration and the theory of rubber. Excellent agreement was found when comparing predictions from the model to experimental data ranging from temperatures of -50°C to 245°C, degree of cure of 0.01 to 1.0 and frequencies of 0.01Hz to 10Hz.
The Dance of the Dead Rhino: William Kentridge’s Magic Flute

Subjects: William Kentridge; The Magic Flute; mourning; colonialism; violence

description: The article offers a reading of the staging of The Magic Flute by visual artist William Kentridge, focusing on his introduction of the rhino in the visual landscape of the opera as symbol for the silenced subject of violence. Operatic tradition has always been concerned with the staging of death, in particular with the death of its female protagonists, and recent scholarship has highlighted the complicity of the genre with the ideology of Western patriarchy and colonial violence. In this light, Kentridge's appropriation stages Mozart's opera as both voice of colonial Europe and place of resistance for the postcolonial artist. Kentridge moves the setting of the opera to colonial Africa, and the Flute becomes haunted with the massacre of the Herero people in South West Africa by the German army led by general von Trotha (1904-1907). The African white rhino, a species under the threat of extinction, works in this work as proxy for the missing corpses of the Herero people; in its being subject to humiliation and ruthless murder, it recalls Judith Butler's recent attempt at a different categorization of human life as both a continuous exposure to violence and what can be mourned after death. With its silence among the powerful sounds of Mozart's opera, the body of the dead, dancing rhino stands at the centre of Kentridge's work, which becomes a ceremony of mourning where the Western canon can be made to "resonate differently" (Trinh T. Minh-ha).

description: Personal Protective Equipment (PPE) is one of the most important strategies for protecting healthcare workers (HCWs) and patients from pathogens. Due to a wide variety of factors, residents of long-term care (LTC) facilities are a population particularly vulnerable to infection, and as such, special attention is needed to prevent infection transmission in LTC settings. While there are guidelines that inform HCWs on when and how to use PPE, these guidelines are not always adhered to. The barriers and facilitators to PPE uptake and appropriate use are unknown in LTC settings and need to be understood to improve the adherence and appropriate use of PPE by HCWs in LTC settings. This thesis aimed to determine what the barriers and facilitators to the use of PPE are.A multi-methods approach was used to address the objectives of the study. A scoping review was conducted to determine what barriers and facilitators to the uptake and appropriate use of PPE have been identified in literature in LTC settings. Common barriers identified in literature included supply issues, the cost of acquisition, unclear guidelines on appropriate use of PPE, difficulty providing care, and anxiety about frightening patient. Having PPE readily available facilitated the use of PPE.One-on-one semi-structured interviews were conducted with LTC HCWs to understand how they perceived the barriers and facilitators to the uptake and appropriate use of PPE and determined if the factors identified in the literature are, or are not, reflected in operations in Calgary Health Zone LTC facilities. The most identified barriers included: a lack of recognition for using PPE appropriately; prioritizing other non-infection transmission focused patient care; the time required to don and doff PPE; and the availability, quality, or comfort of PPE; fear ofiiiscaring residents; and stress and anxiety. Identified facilitators included: a sense of professional duty; a desire to protect themselves or their family; constructive feedback; a strong understanding of the function of PPE; the existence of PPE champions; available training opportunities; ease of use; coworkers as positive role models for PPE use; and attaining a feeling of safety.This thesis identifies the barriers and facilitators to the use of PPE in LTC settings. Recommendations about the next steps for technology development, research, and clinical implementation can be developed based on the findings of this study.

description: Assuming the existence of a primordial asymmetry in the dark sector, a scenario usually dubbed Asymmetric Dark Matter (aDM), we study the effect of oscillations between dark matter and its antiparticle on the re-equilibration of the initial asymmetry before freeze-out, which enable efficient annihilations to recouple. We calculate the evolution of the DM relic abundance and show how oscillations re-open the parameter space of aDM models, in particular in the direction of allowing large (WIMP-scale) DM masses. A typical wimp with a mass at the EW scale (\sim 100 GeV - 1 TeV) presenting a primordial asymmetry of the same order as the baryon asymmetry naturally gets the correct relic abundance if the DM-number-violating Delta(DM) = 2 mass term is in the \sim meV range. The re-establishment of annihilations implies that constraints from the accumulation of aDM in astrophysical bodies are evaded. On the other hand, the ordinary bounds from BBN, CMB and indirect detection signals on annihilating DM have to be considered.

description: Rényi divergence is related to Rényi entropy much like Kullback-Leibler divergence is related to Shannon's entropy, and comes up in many settings. It was introduced by Rényi as a measure of information that satisfies almost the same axioms as Kullback-Leibler divergence, and depends on a parameter that is called its order. In particular, the Rényi divergence of order 1 equals the Kullback-Leibler divergence. We review and extend the most important properties of Rényi divergence and Kullback-Leibler divergence, including convexity, continuity, limits of $σ$-algebras and the relation of the special order 0 to the Gaussian dichotomy and contiguity. We also show how to generalize the Pythagorean inequality to orders different from 1, and we extend the known equivalence between channel capacity and minimax redundancy to continuous channel inputs (for all orders) and present several other minimax results.

description: Problem: Cardiovascular disease (CVD) remains the leading cause of premature death in North American women and is a serious health problem for women worldwide. Recent data suggests that despite overall improvements in cardiovascular mortality over the last decades, the incidence and mortality of coronary heart disease in younger women (25-54 years) is unchanged, highlighting the urgent need to identify sex specific risk factors. Current prevention guidelines may overlook non-traditional risk factors present in women including exogenous estrogen in the form of contraceptives and postmenopausal hormone therapy (HT). Whether contraceptives and HT contribute to increased CV risk is unclear.Preface: Oral estrogen have been associated with elevated cardiovascular risk; although the mechanism is unclear, it has been postulated to increased blood pressure (BP), arterial stiffness and renin-angiotensin aldosterone system (RAAS) activity may a play a role. Whether non-oral estrogen delivery is associated with the same increase in cardiovascular risks is unknown. Landmark studies such as the Women's Health Initiative (WHI) have raised concerns about the safety of HT; particularly those containing oral conjugated equine estrogen (CEE) with and without medroxyprogesterone acetate (MPA). However, more recent analysis of the data suggests that factors including route of administration may mediate the association of HT on CV risk. Whether non-oral methods of HT are associated with similar elevated risks in CVD is unknown.Goal: The aim of this thesis is to evaluate the association between the route of administration of exogenous estrogen, in the form of contraceptives and HT, on measures of cardiovascular risk and disease in women.

description: Natural rubber (NR) is an industrially essential biopolymer due to its irreplicable properties. To date the only necessary components identified for NR biosynthesis are two membrane-bound proteins, cis-prenyltransferase (CPT) and CPT binding protein (CBP) that form a complex in which CPT catalyzes the addition of isopentyl pyrophosphate (IPP) subunits to an allylic primer molecule. Reconstitution of CPT/CBP protein complexes in vitro is insufficient for NR production. Therefore, plant systems are essential for elucidating the factors that influence NR production.Lettuce is an ideal model to study NR as it produces high quality, long NR polymers (Mw ? 1 million Da) and is amenable to molecular genetic studies. In this work a CRISPR-Cas9 gene editing system was used to produce lscpt3 mutants. These mutants were NR deficient, suggesting that LsCPT3 is the sole lettuce CPT paralog responsible for NR biosynthesis. Using this mutant background, NR produced by heterologous CPTs in lettuce laticifers was evaluated. Interestingly, CPTs from guayule and goldenrod produced NR with an average Mw that was 1.8-fold and 14-fold greater than in the native plant. This finding demonstrates that CPT is insufficient in determining NR Mw and suggests that the unique cellular context of lettuce laticifers is an important variable in determining NR Mw.Two paralogs of CBP, LsCBP1 and LsCBP2, have been identified in lettuce. CRISPR-Cas9 was implemented to generate NR deficient lscbp2 mutants with no obvious developmental or physiological phenotypes. This data suggests gene duplication and neofunctionalization of LsCBP2 has resulted in a CBP specific for NR biosynthesis in lettuce.Lettuce also accumulates sesquiterpene lactones (STLs) in its laticifers that pull from the same IPP pool as NR. To understand the coordination of these two metabolites, lettuce lines expressing GUS-promoter constructs for STL biosynthetic genes were produced. These lines revealed that STL genes are localized to the parenchyma cells neighbouring laticifers, despite downstream STLs accumulating in the laticifer. These results contribute to a greater understanding of NR biosynthesis in the model plant lettuce. The unique cellular context of laticifers and evolution of a NR specific CBP provide additional insight for the development of biotech enabled NR production.

description: Adherence to cervical cancer screening (CCS) is critical for decreasing cervical cancer incidence and related mortality. Repeating Pap tests every three years in women with a population-based risk of cervical cancer and annually in high-risk patients, as a risk-appropriate approach, is highly recommended. Women with Inflammatory Bowel Disease (IBD) and exposed to immunosuppressive medications are considered high-risk patients. Promoting adherence to CCS by educational intervention has been studied previously; however, the extent of the impact among IBD patients is still unclear. Our study aims to assess the association between receiving health education, by physicians in the IBD pregnancy clinic, and adherence to CCS. A total of 190 individuals with IBD who visited the IBD pregnancy clinic between 2012 and 2016 were recruited. A one-group pretest-posttest study design was conducted. Data of Pap testing between 2007 and 2020 were collected and compared before (baseline) and after educational intervention by McNemar’s Test. Prior to the intervention, 29.47% (95% CI, 23.37 – 36.4) of participants had adherence to risk-appropriate CCS for two screening cycles before the health education. Importantly, participation in risk-appropriate screening immediately after receiving the health education increased significantly to 47.36% (proportion difference= 0.18, 95% CI, 0.08 – 0.27) (p<0.001). Long-term adherence to the population-based CCS was observed in 38.42% (95% CI, 31.72 – 45.6) of participants before the intervention and 34.74% (95% CI, 28.25 – 41.84) after the intervention. McNemar’s test result indicated no significant change in adherence to CCS for more than one cycle after the intervention (p=0.45). This study demonstrated that the participation rate in CCS among IBD patients, particularly those on immunosuppressive therapy, was less than the target rate determined by the provincial health care system. The participation rate in the first risk-appropriate CCS improved significantly after receiving the educational intervention. However, the longevity of behaviour change was not determined. The finding may be due to the small sample size and diverse Pap testing intervals recommendations in different versions of guidelines. Further investigations are required to address the exact reasons for these findings and design an intervention that translates into prolonged behaviour changes.

description: We examine the validity of the harmonic approximation, where the radio-frequency ion trap is treated as a harmonic trap, in the problem regarding the controlled collision of a trapped atom and a single trapped ion. This is equivalent to studying the effect of the micromotion since this motion must be neglected for the trapped ion to be considered as a harmonic oscillator. By applying the transformation of Cook and Shankland we find that the micromotion can be represented by two periodically oscillating operators. In order to investigate the effect of the micromotion on the dynamics of a trapped atom-ion system, we calculate (i) the coupling strengths of the micromotion operators by numerical integration and (ii) the quasienergies of the system by applying the Floquet formalism, a useful framework for studying periodic systems. It turns out that the micromotion is not negligible when the distance between the atom and the ion traps is shorter than a characteristic distance. Within this range the energy diagram of the system changes remarkably when the micromotion is taken into account, which leads to undesirable consequences for applications that are based on an adiabatic process of the trapped atom-ion system. We suggest a simple scheme for bypassing the micromotion effect in order to successfully implement a quantum controlled phase gate proposed previously and create an atom-ion macromolecule. The methods presented here are not restricted to trapped atom-ion systems and can be readily applied to studying the micromotion effect in any system involving a single trapped ion.
