description: We report the observation of a resonance in the microwave spectra of the real diagonal conductivities of a two-dimensional electron system within a range of ~ +- .0.015 $ from filling factor $ν=1/3$. The resonance is remarkably similar to resonances previously observed near integer $ν$, and is interpreted as the collective pinning mode of a disorder-pinned Wigner solid phase of $e/3$-charged carriers .

Publisher: name: University of Illinois at Chicago

Subjects: Uncategorized

description: Surgeries are always challenging procedures. In ophthalmology in particular, the main difficulties are represented by limited space, complicated viewpoints, and bad light conditions, which make it even harder for surgeons to operate safely. This means avoid touching the retina, i.e. the back surface of the eye, perform secure movements and do not apply too much force on surfaces. This thesis deals with the problem of retinal collision avoidance through a proposed real-time pipeline utilizing both Deep Learning and Computer Vision to provide ophthalmologists with additional information about depth perception.

Finding Ivan Illich in the Writing Center: A Case Study of Deschooling and Literacy Learning
Creators: name: Mayo, Russell F.
Publisher: name: University of Illinois at Chicago
Year: 2020
Subjects: Uncategorized

description: This dissertation presents a case study exploration of peer tutoring in a university writing center (WC) viewed through the lens of “deschooling,” a radical educational theory articulated by social philosopher Ivan Illich. In this manuscript, I explore my personal experiences of schooling in relation to Illich’s work and the rhetoric of Illich’s deschooling thesis. I also present research findings from the Great Lakes State University Writing Center (GLSU-WC, a pseudonym), a unique literacy learning space where students come together to learn about academic writing through pedagogies and interactions that more closely resemble “deschooling” than traditional classroom relations. My overall argument is that GLSU-WC’s pedagogy of reciprocal learning represents an “actually-existing” form of deschooling, albeit one that has developed within and in many ways supported by wider educational structures. That is, I view peer tutoring in the GLSU-WC as resonant with Ivan Illich’s vision for what “education” might look like in a deschooled society, a convivial, user-initiated system that no longer conforms to industrial, commodified forms of education. My central claim is that a deschooling approach to literacy and WCs can offer a radical alternative in and to education. In the end, I discuss how such conceptual questions take on a particular urgency when one considers the exigence of the climate and environmental crises which threaten to completely reshape human society and our environment in the coming decades. My purpose for this project is two-fold. First, I aim to revive the overlooked, critical scholarship of Ivan Illich, showing the relevance of Illich’s writing for scholars across English education, literacy, composition/rhetoric, writing centers, educational philosophy, learning theory, and environmental studies. In addition, this work presents argument about the importance of the peer-to-peer learning model for reimagining sustainable forms education in the Anthropocene.

description: Past studies of the Hohokam irrigation systems have focused on the examination of small segments of individual prehistoric canals. The application of open channel equations to individual cross-sections has provided information on discharge capacity and water velocity at specific points in time and space. This study focuses on the development of techniques and approaches to modeling the operation of complete canals. Extant records of cross-sections of the Prehistoric Hohokam canals are compiled for Canal System 2. The basic hydraulic variables are calculated for all available cross-sections. A "linking analysis" is formulated to match up widely spaced cross-sections across the same canal to examine change through the longitudinal section. A regression analysis is used to model the change in hydraulic variables including total cross-sectional area, paleodischarge and velocity. The regression model is applied to all canal cross-sections. Secondary variables are generated including total canal volume in m3 and discharge in acre feet entering the canal head. Data generated from the modeling procedure are used to produce estimates of total irrigated acres and labor input required for the construction of specific canals. A diachronic analysis is conducted, with all. of the canals reconstructed for Canal System 2 being segregated by chronological period. Within each chronological period groups of contemporaneous canals are identified to characterize total system capacity and construction requirements. Changing system requirements are then examined and contrasted with previous models of demographic change, organizational requirements and sociopolitical complexity in the Salt River Valley.

description: CONTEXT: The small radius and high density of CoRoT-7b implies that this transiting planet belongs to a differen t species than all transiting planets previously found. Current models suggest that this is the first transiting rocky planet found outside the solar system. Given that the planet orbits a solar-like star at a distance of on ly 4.5 R*, it is expected that material released from its surface may then form an exosphere. AIMS: We constrai n the properties of the exosphere by observing the planet in- and out-of-transit. Detecting of the exosphere of CoRoT-7b would for the first time allow to study the material originating in the surface of a rocky extrasolar planet. We scan the entire optical spectrum for any lines originating from the planet, focusing particularly on spectral lines such as those detected in Mercury, and Io in our solar system. METHODS: Since lines originating in the exosphere are expected to be narrow, we observed CoRoT-7b at high resolution with UVES on the VLT. By subtracting the two spectra from each other, we search for emission and absorption lines originating in the exosph ere of CoRoT-7b. RESULTS: In the first step, we focus on Ca I, Ca II, Na, because these lines have been detected in Mercury. Since the signal-to-noise ratio (S/N) of the spectra is as high as 300, we derive firm upper limits for the flux-range between 1.6E-18 and 3.2E-18 Wm**-2. For CaO, we find an upper limit of E-17 Wm**-2. We also search for emission lines originating in the plasma torus fed by volcanic activity and derive upper limits for these lines. In the whole spectrum we finally try to identify other lines originating in the planet.

description: A critique of a recent paper [Mallamace et al PNAS 2010 107 (52) 22457-2246] purporting the existence of a fragile-to-strong crossover in super cooled liquids is presented. It is shown that Mallamace et al have mistaken the onset crossover with the fragile-strong crossover. Moreover, it is shown that supercooled liquid transport data follows the expected parabolic function, without a crossover to another functional form, and that Mallamace et al have obscured this fact by singling out anomalous data as examples.

description: Bioactive natural compounds are of strategic importance in modern medicine. In a period from 1981 to 2014 U.S. Food and Drug Administration approved over 1300 new molecular entities to treat diverse spectrum of conditions, and among these substances unmodified natural products and their direct analogs represent 43% of registered compounds. While inspecting chemical composition of such molecules one can quickly identify enones and their derivatives to be common structural motif. Our research goals were shaped around contribution of synthetic knowledge regarding total chemical synthesis of enone-based biologically active natural products of low abundance, along with development of new synthetic tools that allow transformation of enones into other functional groups, critical in preparation of even broader class of medicinal targets. We successfully demonstrated that enone-derived vinylogous esters can be converted into twelve different phenolic natural compounds of medicinal interest in a very short and highly efficient manner. We also showed that halogenated nature of thus-created aromatic fragments can be incorporated into further synthetic sequence by performing coupling reactions between aryl halide and alkenes as their side tethers. Furthermore, developed oxidative aromatization conditions can be applied to hydrogen-deficient enone systems, and resulting polyhalogenated enones can be used in a preparation of corresponding natural products. Regioselective functionalization of enones also allowed us to explore new synthetic technologies available in this area. Specifically, we successfully developed three Ni-catalyzed transformations on electron-rich anilines that allowed us to convert single universal intermediate into corresponding de-functionalized anilines and indoles of medicinal importance. Finally, we were also able to investigate variety of enantioselective remote functionalization reaction of enones. We showed the possibility of γ-arylation of enone-derived dienol sylil ethers with phenyl bromide into enantioenriched arylated enones under Ni-catalyzed reaction conditions.

description: In this short reappraisal of spontaneous lepton number violation in a supersymmetric scenario implemented through singlet sneutrino vacuum expectation value (VEV), we contribute with two new things in the context where the lepton number symmetry is global: (i) provide explicit expressions of $R$-parity violating couplings in terms of the neutrino Yukawa couplings and the singlet sneutrino VEV, and (ii) estimate the limit on this VEV using the current knowledge of the light neutrino mass and the astrophysical constraint on the Majoron-electron coupling. Besides, we put updated constraints on the VEV and Yukawa coupling of the singlet superfield when lepton number is gauged.

Quantum Statistical Relation for black holes in nonlinear electrodynamics coupled to Einstein-Gauss-Bonnet AdS gravity

description: We consider curvature-squared corrections to Einstein-Hilbert gravity action in the form of Gauss-Bonnet term in D>4 dimensions. In this theory, we study the thermodynamics of charged static black holes with anti-de Sitter (AdS) asymptotics, and whose electric field is described by nonlinear electrodynamics (NED). These objects have received considerable attention in recent literature on gravity/gauge dualities. It is well-known that, within the framework of anti de-Sitter/Conformal Field Theory (AdS/CFT) correspondence, there exists a nonvanishing Casimir contribution to the internal energy of the system, manifested as the vacuum energy for global AdS spacetime in odd dimensions. Because of this reason, we derive a Quantum Statistical Relation directly from the Euclidean action and not from the integration of the First Law of thermodynamics. To this end, we employ a background-independent regularization scheme which consists in the addition to the bulk action of counterterms that depend on both extrinsic and intrinsic curvatures of the boundary (Kounterterm series). This procedure results in a consistent inclusion of the vacuum energy and chemical potential in the thermodynamic description for Einstein-Gauss-Bonnet AdS gravity regardless the explicit form of the NED Lagrangian.

Year: 2017

description: Saudi Arabian student enrollment in undergraduate programs has been increasing over the years in postsecondary institutions worldwide. This has been more so in English speaking countries. Yet, there has been no research investigating Saudi undergraduate students’ living and learning experiences in postsecondary institutions abroad. Hence, the study reported in this thesis explored through a qualitative case study Saudi Arabian undergraduate students’ experiences at a Western Canadian University (WCU). The goal was to understand the nature of Saudi students’ living and learning experiences during their study abroad and in particular at a WCU. Involvement and sociocultural theoretical frameworks and narrative methodology were employed to interview 10 undergraduate students from Saudi Arabia studying at WCU. Narrative method of interviewing allowed the students to tell stories of their living and learning experiences at WCU. A search for common patterns within each individual story and across the stories revealed two key themes common to their experiences: 1) “Expression of an Understanding of Educational Systems and the Complexities and Challenges of Attending a Canadian University”, manifest in both: a) academic; and b) language encounters; and 2) “Expression of Understanding Social Complexities”, which manifested in encounters involving: 1) new cultures and environments; and 2) different rules and responsibilities. The study’s findings reveal insights into the challenges and successes experienced by Saudi Arabian students studying at a WCU and personal responsibilities they considered to be successful as well as offer suggestions for ways stakeholders can make Saudi student study at WCU a rewarding experience.
Affective Ecology as development of biophilia hypothesis
Creators: name: Barbiero, Giuseppe
Publisher: name: Visions for Sustainability
Year: 2021

description: Affective ecology is the branch of ecology that deals with the cognitive and emotional relationships that humanity and Gaia establish between themselves. In the last ten years, affective ecology has engaged above all in the experimental verification of the biophilia hypothesis and in defining the two fundamental constructs of biophilia: fascination and affiliation. The definition of such constructs allows us to estimate more precisely the psychological effects of biophilia. Fascination for Nature triggers the restoration of cognitive skills after mental fatigue, while the feeling of affiliation for Nature has a stress-reducing effect. The experimental outcomes allow us to design an ideal biophilic environment, able to stimulate fascination and affiliation for Nature. A biophilic environment is the ideal environment for developing naturalist intelligence. The future perspectives of affective ecology concern the search for high biophilic quality environments, which can be both inner environments, as in the case of Green Mindfulness in ecopsychology, and outer environments as in the case of Biophilic Design in architecture.

Not able to resist the urge : social insider attacks on Facebook
Creators: name: Usmani, Wali Ahmed
Publisher: name: University of British Columbia
Year: 2017

description: Facebook accounts are secured against unauthorized access through passwords, and through device-level security. Those defenses, however, may not be sufficient to prevent social insider attacks, where attackers know their victims, and gain access to their accounts using the victim's device. To characterize these attacks, we ran two Amazon Mechanical Turk studies geographically restricting participant pool to US only. Our major goal was to establish social insider attack prevalence and characteristics to justify a call to action for better protective and preventative countermeasures against it. In the first study involving 1308 participants, we used the list experiment, a quantitative method to estimate that 24% of participants had perpetrated social insider attacks, and that 21% had been victims to it (and knew about it). In the second, qualitative study with 45 participants, we collected stories detailing personal experiences with such attacks. Using thematic analysis, we typified attacks around 5 motivations (fun, curiosity, jealousy, animosity and utility), and explored dimensions associated with each type. Our combined findings indicate a number of trends in social insider attacks. We found that they are common, they can be perpetrated by almost all social relations and often have serious emotional consequences. Effective mitigation would require a variety of approaches as well as better user awareness. Based on the results of our experiments, we propose methodological steps to study the perception of severity of social insider attacks. In this procedure, we include an experimental design of the study and its possible limitations. The study consists of presenting stories collected in the previously mentioned second study to a new cohort of participants. It the asks them to provide a Likert Scale rating and justification for how severe they perceive the attack in the story to be if they were the victim as well as how likely they feel they might be a victim to such an attack. Lastly, we discuss possible future work in creating countermeasures to social insider attacks, their viability and limitations. We conclude that no single technique is complete solution. Instead mitigation will require a number of techniques in combination to be effective.

description: We investigate the behavior of light baryon masses in three inequivalent large-$N_c$ limits: 't~Hooft, QCD$_{\rm AS}$ and Corrigan-Ramond. Our framework is a constituent quark model with relativistic-type kinetic energy, stringlike confinement and one-gluon-exchange term, thus leading to well-defined results even for massless quarks. We analytically prove that the light baryon masses scale as $N_c$, $N_c^2$ and $1$ in the 't~Hooft, QCD$_{\rm AS}$ and Corrigan-Ramond limits respectively. Those results confirm previous ones obtained by using either diagrammatic methods or constituent approaches, mostly valid for heavy quarks.

description: We consider a free massless scalar field coupled to an infinite tower of background higher-spin gauge fields via minimal coupling to the traceless conserved currents. The set of Abelian gauge transformations is deformed to the non-Abelian group of unitary operators acting on the scalar field. The gauge invariant effective action is computed perturbatively in the external fields. The structure of the various (divergent or finite) terms is determined. In particular, the quadratic part of the logarithmically divergent (or of the finite) term is expressed in terms of curvatures and related to conformal higher-spin gravity. The generalized higher-spin Weyl anomalies are also determined. The relation with the theory of interacting higher-spin gauge fields on anti de Sitter spacetime via the holographic correspondence is discussed.

description: Neurogenerative disorders such as Alzheimer’s Disease (AD) and related dementias are a growing problem since the global population is aging more and more. It is important to develop automated methods that can be aid in identifying the first symptoms of these diseases to better treat them from their earliest stages. Speech and language alterations are one of the first signs of dementia and this work is focused on developing an automated methodology that starting from patients’ linguistic samples can spot the presence of linguistic patterns that are related to dementia of the AD type. We are comparing different neural network models that starting from patients’ conversational transcripts use syntactic and semantic features to classify AD patients and Healty Control (HC) patients. We are then performing feature selection to understand what kind of feature plays a more significant role in the classification. Finally, we are interpreting some portions of the models proposed to analyze specific linguistic patterns linked with dementia of the AD type.

description: The particle production process is reviewed, through which cosmic inflation can produce a scale invariant superhorizon spectrum of perturbations of suitable fields starting from their quantum fluctuations. Afterwards, in the context of the inflationary paradigm, a number of mechanisms (e.g. curvaton, inhomogeneous reheating etc.) through which such perturbations can source the curvature perturbation in the Universe and explain the formation of structures such as galaxies are briefly described. Finally, the possibility that cosmic vector fields also contribute to the curvature perturbation (e.g. through the vector curvaton mechanism) is considered and its distinct observational signatures are discussed, such as correlated statistical anisotropy in the spectrum and bispectrum of the curvature perturbation.

A Randomized Algorithm Based on Threshold Accepting to Approximate the Star Discrepancy

description: We present a new algorithm for estimating the star discrepancy of arbitrary point sets. Similar to the algorithm for discrepancy approximation of Winker and Fang [SIAM J. Numer. Anal. 34 (1997), 2028--2042] it is based on the optimization algorithm threshold accepting. Our improvements include, amongst others, a non-uniform sampling strategy which is more suited for higher-dimensional inputs, and rounding steps which transform axis-parallel boxes, on which the discrepancy is to be tested, into \emph{critical test boxes}. These critical test boxes provably yield higher discrepancy values, and contain the box that exhibits the maximum value of the local discrepancy. We provide comprehensive experiments to test the new algorithm. Our randomized algorithm computes the exact discrepancy frequently in all cases where this can be checked (i.e., where the exact discrepancy of the point set can be computed in feasible time). Most importantly, in higher dimension the new method behaves clearly better than all previously known methods.

description: How can one discriminate different inequivalent classes of multiparticle entanglement experimentally? We present an approach for the discrimination of an experimentally prepared state from the equivalence class of another state. We consider two possible measures for the discrimination strength of an observable. The first measure is based on the difference of expectation values, the second on the relative entropy of the probability distributions of the measurement outcomes. The interpretation of these measures and their usefulness for experiments with limited resources are discussed. In the case of graph states, the stabilizer formalism is employed to compute these quantities and to find sets of observables that result in the most decisive discrimination.

Subjects: Uncategorized

description: This study explores the issue of media piracy from the perspectives of audience, which is a topic that has not been examined sufficiently. In doing so, this study narrows the population of the study to a diaspora since diasporic audience has attracted little scholarly attention in media piracy literature. To understand the diasporic audience’s perspective on media piracy, the study utilizes the Korean diaspora and a petition started by the Korean file-sharing website. A file-sharing website used and managed by Korean diasporic audiences, Dabdate, started a petition to stop Korean broadcasting stations from shutting down the website for copyright violation. This study conducts a frame analysis to understand the perspectives of the Korean diasporic audience from news articles, online community posts, and Dabdate’s petition endorsements collected over about a month. The findings revealed that the diasporic audience’ perspective did not align with that of the industry. The media industry’s claim that media piracy has caused enormous damage did not appear anywhere but the Korean diasporic news articles. When Korean diasporic users shared the sentiment, they were facing a sanction due to media piracy. The Korean diasporic audiences considered the Korean media as a public good, which they were entitled as free access by law. Thus, in their eyes, media piracy was not as problematic as the industry claimed. Korean media consumption was also a way to maintain the Korean identity for the Korean diasporic audiences, especially so for those in areas with small Korean immigrant communities. Some Korean diasporic audiences found copyright reinforcement efforts offensive and as a disenfranchisement of their identity as Korean citizens and Koreans.

description: We report the discovery of large amounts of cold (T ~ 10^4 K), chemically young gas in an overdensity of galaxies at redshift z ~ 1.6 in the Great Observatories Origins Deep Survey southern field (GOODS-S). The gas is identified thanks to the ultra-strong Mg II absorption features it imprints in the rest-frame UV spectra of galaxies in the background of the overdensity. There is no evidence that the optically-thick gas is part of any massive galaxy (i.e. M_star > 4x10^9 M_sun), but rather is associated with the overdensity; less massive and fainter galaxies (25.5 < z_850 < 27.5 mag) have too large an impact parameter to be causing ultra-strong absorption systems, based on our knowledge of such systems. The lack of corresponding Fe II absorption features, not detected even in co-added spectra, suggests that the gas is chemically more pristine than the ISM and outflows of star-forming galaxies at similar redshift, including those in the overdensity itself, and comparable to the most metal-poor stars in the Milky Way halo. A crude estimate of the projected covering factor of the high-column density gas (N_H >~ 10^20 cm-2) based on the observed fraction of galaxies with ultra-strong absorbers is C_F ~ 0.04.

description: GaAs nanowires are grown by molecular beam epitaxy using a self-catalyzed, Ga-assisted growth technique. Position control is achieved by nano-patterning a SiO2 layer with arrays of holes with a hole diameter of 85 nm and a hole pitch varying between 200 nm and 2 \mum. Gallium droplets form preferentially at the etched holes acting as catalyst for the nanowire growth. The nanowires have hexagonal cross-sections with {110} side facets and crystallize predominantly in zincblende. The interdistance dependence of the nanowire growth rate indicates a change of the III/V ratio towards As-rich conditions for large hole distances inhibiting NW growth.

description: This dissertation analyzes the interaction that exists between the visual and verbal imageries in the work of Cuban writer and painter Severo Sarduy. The overall structure of the study takes the form of five chapters, including the introduction. In CHAPTER One), I critically examine Sarduy’s references for art in his theoretical texts written during the mid-1960s-1980s: Escrito sobre un cuerpo (1969), Antología: “Cromoterapia.” (1974), and Christ on the Rue Jacob: “Severo Sarduy, why do you Paint?” (1987). This section contains text-as-process, where Sarduy establishes a dialogic mode of performativity between word and image. He delineates and expands the readability of visual objects, the application of semiotics to the visual arts, and enables a fresh account of the experience of any artist, painter or writer, in the origin of their creation. CHAPTER Two) is exclusively dedicated to his series of paintings, a pictorial line of work that started in the 1960s and did not stop until shortly before his death in 1993. CHAPTER Third and Fourth) explores Sarduy’s pictographic gestures in literature. I present a critical reading of his novels Cobra (1972), Maitreya (1978), and Colibrí (1984) from a visual artistic point of view. I uphold my reading with a review of his neobaroque mechanisms: substitution, proliferation, and condensation. Also, confronted with different ekphrastic readings from critics across disciplines I feel inclined to craft another term to my disposal, “ekphrastic juncture,” where image and text co-obstruct and, in the process, illuminate each other. Across my study, I answer questions to understand the Sarduyan ekphrastic model. How do writers reconstruct the visual image, how do they make it corporeal, turn it into color, or action, such that readers can begin to visualize it? What specific resources do readers use when they try to apprehend what is described in words?
They're limited by their circumstances...maybe it's the best they can do : public health nurses' understanding of their work with families living with social and material disadvantages

description: Public health nurses (PHNs) have a long history of supporting the health of families living with social and material disadvantages. Professional nursing organizations, researchers and theorists emphasize that consideration of the social determinants of health and efforts to address health inequities are critical components of nursing’s mandate. Literature emphasizes that nurses’ practices are shaped by personal, organizational and ideological factors that influence their assumptions about, and understanding of their role with, vulnerable families. Literature also highlights the need for PHNs to engage in critical reflection about their personal assumptions regarding their clients in order to provide care that is socially just. The purpose of this qualitative study is to explore the range of understandings and assumptions PHNs may hold about families living with social and material disadvantages, how PHNs understand their work with these families and the ways in which PHNs reflect on their assumptions and nursing practice. The specific research questions are: What is the range of assumptions that PHNs have in relation to families living with social and material disadvantages? How do PHNs understand their work with families living with disadvantages? How do PHNs describe engagement in self-reflection regarding their assumptions about clients living with disadvantages and how does this impact the PHNs’ nursing practice? What can be learned from the perspective of expert PHNs on the ways that nurses can work effectively with families living with social and material disadvantages? What recommendations can be generated to help support PHNs working with families living with social and material disadvantages? A qualitative exploratory research design was used to address these research objectives. Six, experienced PHNs participated in interviews with the researcher. The findings are organized around five main themes: (i) understanding clients’ context and engaging with individuals and families, (ii) building trusting relationships, (iii) PHNs are one agent, among many, that may influence change, (iv) recognizing the significance of small increments of change, (v) PHNs’ practice has a primary focus on mothers and children. PHNs valued opportunities to engage in self-reflection, but identified barriers to this practice. Recommendations are suggested in domains of education, organizations, PHNs’ practice and research.

description: Anomalous diffusion has been widely observed by single particle tracking microscopy in complex systems such as biological cells. The resulting time series are usually evaluated in terms of time averages. Often anomalous diffusion is connected with non-ergodic behaviour. In such cases the time averages remain random variables and hence irreproducible. Here we present a detailed analysis of the time averaged mean squared displacement for systems governed by anomalous diffusion, considering both unconfined and restricted (corralled) motion. We discuss the behaviour of the time averaged mean squared displacement for two prominent stochastic processes, namely, continuous time random walks and fractional Brownian motion. We also study the distribution of the time averaged mean squared displacement around its ensemble mean, and show that this distribution preserves typical process characteristic even for short time series. Recently, velocity correlation functions were suggested to distinguish between these processes. We here present analytucal expressions for the velocity correlation functions. Knowledge of the results presented here are expected to be relevant for the correct interpretation of single particle trajectory data in complex systems.

Retinal Segmentation of Intraoperative B-Scan Optical Coherence Tomography Using Deep Learning

description: The epiretinal membrane is a condition in which a small bro cellular scar tissue forms on the surface of the retina. This membrane can distort, reduce or block completely the patient eyesight. The ophthalmologist can intervene by peeling the scar tissue from the retina surface. Removing an object close to the retina can have complications. Small movements of surgical tools can touch and damage the retina. Moreover, peeling the scar tissue can produce unwanted stress on the retina surface, with possible retina detachments, that can impair the normal eyesight of the patient. Due to these complications, support tools are needed during the surgical operation in order to reduce possible accidents. Nowadays one of the most used tools is the intraoperative Optical Coherence Tomography (iOCT). The iOCT serves the same purpose as a standard Optical Coherence Tomography (OCT) but is enhanced for real-time usage. Unfortunately, this speed enhancement reduces the quality of the image artifacts produced by the iOCT, thus making it challenging to identify the retina location. The iOCT produces a cross-section pair of images of the retina, and displays them to the surgeon in real-time. We propose a support tool that utilizes the cross images produced by iOCT and automatically detects the retina in real-time, helping the surgeon identify correctly the retina boundaries. We will show the execution times and accuracy of the proposed algorithm, together with possible future expansions to the project.
