Year: 2013

description: Diese Arbeit verwendet das Konzept des „adaptiven Zyklus“ aus der sozio–ökologischen Resilience-Theorie um die Entwicklung archäologischer Kulturen zu beschreiben. Einleitend werden die vier Phasen (Wachstums-, Konservierungs-, Auflösungs-, und Reorganisationsphase) des „adaptiven Zyklus“ vorgestellt. Im zweiten Teil wird in einem Fallbeispiel die Entwicklung der Linearbandkeramik im Rheinland als „kultureller Zyklus“ dargestellt.
description: In this paper the concept of “adaptive cycles”, derived from the socio-ecological Resilience Theory, is employed to describe the development of archaeological cultures. First the four phases (growth, conservation, release and re-organisation) of the “adaptive cycle” are introduced. In a case study the development of the Linearbandkeramik Culture in the Rhine-Basin is portrayed as a “cultural cycle”.

description: Formatives Assessment mithilfe technologischer Werkzeuge bietet viele Möglichkeiten, das Lernen zu unterstützen, sowohl im Präsenz- als auch Distanzunterricht. Das Denken beim fachlichen Verständnis von Lernenden schnell und einfach zu erfassen, ist essentiell für eine gezieltes formatives Assessment. In der Regel ist für eine tiefgehende didaktische Diagnose allerdings ein erheblicher Aufwand erforderlich. Viele digitale Diagnoseinstrumente erheben hier den Anspruch, effizient und schnell zu unterstützen. Die meisten digitalen Diagnosewerkzeuge ermitteln zwar den Lernstand, indem sie untersuchen, wie häufig richtig oder falsch geantwortet wurde. Diese Häufigkeiten geben jedoch keinen ausreichenden Einblick in das fachliche Verständnis der Lernenden zum jeweiligen mathematischen Inhalt. Dies bieten hingegen verstehensorientierte, digitale, formative Diagnosetools wie das SMART-System, das in Australien entwickelt wurde (Stacey et al., 2018) und derzeit in Deutschland adaptiert und implementiert wird. Unser begleitendes Forschungsprojekt ist im Bereich der Algebra angesiedelt und konzentriert sich auf das Verständnis von Variablen.

Reactive control of velocity fluctuations using an active deformable surface and real-time PIV
Creators: McCormick, Findlay
Publisher: name: University of Alberta Library
Year: 2023

This work investigated the use of an active deformable surface and real-time particle image velocimetry (RT-PIV) for reactive control of periodic vortex shedding from a wall-mounted spherical cap immersed in a laminar boundary layer. The reactive control strategies involved locally targeting wall-normal (v) or streamwise (u) velocity fluctuations with velocity fluctuations induced by wall-normal surface deformations that comply with or oppose the measured velocity fluctuations. These strategies were inspired by similar ones that were numerically investigated by Choi et al. (1994). Our investigation found that the reactive control strategies generally inhibited the penetration of sweep motions towards the wall. Among the investigated strategies, those employing opposing v-control and compliant u-control demonstrated the greatest inhibition of sweep motions. As well, the reactive control strategies caused significant disruption of the periodic vortex shedding process with the extent of disruption being related to the amplitude of actuations. The greatest disruption was achieved by v-control applying opposing actuations. The opposing v-control cases applying the strongest actuations reduced the energy of two POD modes associated with vortex shedding by up to 69% relative to the unforced flow. For many of the cases that showed the greatest disruption of the periodic flow, the turbulent kinetic energy (TKE) of the flow was also increased relative to the unforced flow. Opposing actuation cases of v -control and compliant actuation cases of u-control exhibited the lowest TKE values on average. Consequently, these cases of reactive control proved to be the most effective at decreasing the energy of the vortex shedding process with minimal additional energy introduced in the form of other flow motions.

The role of capicua in adult hippocampal neurogenesis
Creators: Hourigan, Brenna
Publisher: name: University of Alberta Library
Year: 2023

Adult hippocampal neurogenesis (AHN) involves generating hippocampal granule neurons and the subsequent integration of granule neurons into the hippocampus synaptic circuit. This continuous neuron generation supports ongoing learning and memory formation. Consequently, dysregulation of AHN and impairment of synaptic integration have been implicated in various neurological disorders including Alzheimer’s disease, pathological aging, and stress. Thus, by studying the regulation of AHN and how granule neurons are generated, it is possible to identify therapeutic targets which can lead to more effective treatment options for these disorders. To generate functional adult-born neurons, neural progenitor cells proliferate to expand the precursor cell pool and differentiate into neurons. Newly generated cells then undergo postmitotic maturation to migrate to their final destination and develop elaborate dendritic branching, which allows them to receive input signals. Little is known about factors that regulate neuronal differentiation, migration, and dendrite maturation during adult hippocampal neurogenesis. This thesis highlights the importance of the transcriptional repressor capicua (CIC) for AHN. I show that CIC is dynamically expressed within the adult dentate gyrus of the hippocampus, where AHN occurs. The Cre-loxP system was utilized to generate Emx1-Cre; Cicflox/flox mice to remove CIC from forebrain excitatory neurons, including those involved with AHN. By using the Emx1-Cre; Cicflox/flox knockout mice line in combination with immunofluorescence studies, I show that conditionally deleting Cic from the mouse dentate gyrus compromises the adult neural progenitor cell pool without altering their proliferative potential. I further demonstrate that the loss of Cic impedes neuronal lineage development and disrupts dendritic arborization and migration of adult-born neurons. This study uncovers a previously unrecognized role of CIC in neurogenesis of the adult dentate gyrus.

description: Mathematik wird vielfach als eine Wissenschaft der Muster und Strukturen bezeichnet. Muster und Strukturen stellen schon in der frühen mathematischen Bildung einen bedeutsamen mathematischen Inhaltsbereich dar (KMK, 2005). Zu Beginn der Primarstufe gehört unter anderem das Fortsetzen von Mustern der Form ●●●●●● zu üblichen Tätigkeiten im Inhaltsbereich Muster und Strukturen (Benz et al., 2015). In der frühen mathematischen Bildung werden Musterfolgen unter anderem in Form von statischen Mustern behandelt (Lüken, 2012). Statische Muster bestehen aus einer Grundeinheit (z. B. ●●), die sich kontinuierlich wiederholt (z. B. ●●●●●●). Die Grundeinheit statischer Muster kann sich hinsichtlich ihrer Länge (●● vs. ●●●), ihrer Struktur (●●● vs. ●●●) oder der Art der Repräsentation (●● vs. 1 4) unterscheiden. Bislang existieren jedoch wenige Erkenntnisse über die Vorgehensweisen von Kindern beim Fortsetzen solcher Musterfolgeaufgaben (Baumanns et al., 2022; Lüken & Sauzet, 2021). Erkenntnisse hierzu sind jedoch notwendig, um Kinder beim Aufbau von Fähigkeiten im Inhaltsbereich Muster und Strukturen zu unterstützen. Die vorliegende Pilotstudie untersucht im Rahmen des Erasmus+-Projekts DIDUNAS die Vorgehensweisen von Erstklässler* innen mithilfe von Eye-Tracking. Eye-Tracking hat sich in der Vergangenheit als nützlich erwiesen, um Vorgehensweisen von Schüler*innen zu untersuchen (Schindler et al., 2020). Den folgenden Fragestellungen wird nachgegangen: Welche Vorgehensweisen verwenden Erstklässler*innen bei Musterfolgeaufgaben? Gibt es Unterschiede in der Verwendung von Vorgehensweisen bei Musterfolgeaufgaben zwischen verschiedenen Arten von Mustern?
Online Predictions, RL and Water Treatment: A GVF Story
Creators: Janjua, Muhammad Kamran
Publisher: name: University of Alberta Library
Year: 2023

We study the use of reinforcement-learning based prediction approaches for a real drinking-water treatment plant. Developing such a prediction system is a critical step on the path to optimizing and automating water treatment. Before that, there are many questions to answer about predictability of the data, suitable neural network architectures, how to overcome partially observability, and more. We describe this dataset, and highlight challenges with seasonality, nonstationarity, partial observability and heterogeneity across sensors and operation modes of the plant. We then describe General Value Function (GVF) predictions---discounted cumulative sums of observations--and highlight why they might be preferable to classical n-step predictions common in time series prediction. We discuss how to use offline data to appropriately pre-train our temporal difference learning (TD) agents that learn these GVF predictions, including how to select hyperparameters for online fine-tuning in deployment. We find that the TD prediction agent obtains an overall lower normalized mean-squared error than the n-step prediction agent. Finally, we show the importance of learning in deployment, by contrasting to a TD agent trained purely offline with no online updating. This final result is one of the first to motivate the importance of adapting predictions in real-time, for non-stationary high-volume systems in the real-world. Before we can hope to control a complex industrial facility, we must first ensure that learning of any kind is feasible. This work represents such a feasibility study.

Vision-assisted behavior-based construction safety: Integrating computer vision and natural language processing
Creators: Wang, Yiheng
Publisher: name: University of Alberta Library
Year: 2023

Background: Construction sites can be hazardous places. Behavior-based safety is a method to optimize workers’ behaviors and improve site safety. Previous behavior-based safety has been criticized for their low efficiency because of manual observation. The community has conducted enormous studies about applying advanced computer vision-based methods to automate the monitoring and observation of construction sites. However, the lack of methods for extracting semantic information and identifying safety hazards from construction imagery still poses a significant challenge for the development of sophisticated vision-assisted behavior-based safety programs.

Objectives: This research aims to automate the processes where the manual observation and inspection is needed in the traditional construction safety management by (1) enrich the information could be extracted from construction images, supporting safety hazard identification, (2) automate the safety hazard identification on site, and enable reasoning about the hazard identification according to safety regulations, and (3) automate the image records management and retrieval for efficient safety analysis.

Methods: Firstly, this research proposes a method to extract objects, activities, and interaction information from construction images. This method utilizes image captioning techniques to generate image captions for construction images containing semantic information. Secondly, this research proposes a novel visual–text semantic similarity method to compare construction image captions with safety regulation rules, enabling automatic safety hazard identification and reasoning. Finally, this research proposed a novel content-based image retrieval method for construction image repositories-based object detection. This will help safety managers query and retrieve similar cases from monitoring image records, and conduct behavior analysis.

Outcomes: This research will improve the current vision-based construction management applications in the following ways: (1) it helps automate the monitoring and observation of construction sites; (2) it provides an automated method to identify potential safety hazards on construction sites and give reasoning of their violation about safety rules; and (3) it provides an information retrieval system for construction image repositories, enabling fast image retrieval and case-based reasoning and analysis.

Refinement of Methodology in Ex-Situ Lung Perfusion
Creators: Forgie, Keir
Publisher: name: University of Alberta Library
Year: 2023

Lung transplantation is the gold-standard treatment for eligible patients with end-stage lung disease; however, there is an inadequate supply of high-quality donor lungs for transplant, resulting in a wait-list mortality of 15-30%. Ex-situ Lung Perfusion (ESLP) has become an established means of increasing the donor pool over the last twenty years. Significant progress has been made to extend ESLP preservation from 4-hours to 12-hours in the pre-clinical realm. Unfortunately, clinically approved ESLP preservation is still limited to 4-6 hours, but this will continue to expand along with clinical familiarity. A few preclinical ESLP protocols, including our own, have managed to achieve 24-hours of continuous preservation with porcine lungs, although only one platform has managed to achieve adequate reliability for successful in-vivo transplantation assessment. Xenogeneic cross-circulation ESLP and cyclic ESLP (prolonged cold static preservation [CSP] with brief intermittent periods of ESLP) have successfully achieved total preservation durations of 36-72 hours; however, these approaches deviate from the core tenets of ESLP: 1) isolation of the lungs from other organ systems with vulnerable physiology, and 2) continuous physiologic assessment.

    For ESLP to reach its full potential and optimize the pool of donor lungs, we believe that ultra-prolonged continuous and isolated preservation that allows for increased dwell time of advanced therapeutics is essential (i.e., without cyclic CSP interruption or vulnerable host dependent cross-circulation). A preservation window of 36- to 48 -hours could eliminate global geographic barriers to transplant and organ sharing, allow for optimized donor-recipient matching with more thorough assessment, and enable the expansion of the donor pool by treating and improving poor quality lungs with advanced pathologies. Our lab has previously established that our unique Negative Pressure Ventilation (NPV)-ESLP device produces less lung injury and inflammation compared to a standard Positive Pressure Ventilation (PPV)-ESLP strategy. Therefore, NPV-ESLP is well-positioned to be the ideal platform for ultra-prolonged ESLP. Hence, the objectives of this thesis are to: 1) Develop a clinically relevant large animal lung transplant model to validate ESLP physiology via in-vivo assessment; 2) Systematically investigate key aspects of our current ESLP protocol, including temperature, flow rate, blood-gas management, and perfusate management, for further optimization as demonstrated through improved acute transplant outcomes; 3) Apply our refined protocol to achieve a reliable 24-hour NPV-ESLP transplant model, and push the envelope to achieve 36-hours of continuous, isolated ESLP preservation, which would represent a milestone achievement.
Family Life Courses of Older Caribbean Migrants Living in Canada
Creators: Donalds, Shanika
Publisher: name: University of Alberta Library
Year: 2023

The multidimensional nature of family life can make navigating relationships across distance and time complex. As families become more mobile there is acknowledgment of a knowledge gap in understanding how family dynamics and bonds extend across borders. Issues of continuity and change within families become more salient to understanding how family members near and far navigate relationships and obligations across time. The focus of this study was to explore migrants’ perspectives of their family life courses.

This qualitative descriptive study sought to ascertain older migrant perspectives on their family relationships across the life course. The study was guided by human ecology theory, social convoy model and concepts from life course perspective to facilitate understanding of the experiences of the older adults. The thematic findings from this study affirm the significance of family bonds, illustrating that: family relationships are negotiated across time; family relationships are enacted via various mechanisms; and ideas about families are redefined across time. The study results suggest that, in the face of a life event such as migration participants actively engaged in decision making about the family relationships that they nurture, new relationships that they create and those they would leave behind.

description: Text in video is useful and important in indexing and retrieving the video documents efficiently and accurately. In this paper, we present a new method of text detection using a combined dictionary consisting of wavelets and a recently introduced transform called shearlets. Wavelets provide optimally sparse expansion for point-like structures and shearlets provide optimally sparse expansions for curve-like structures. By combining these two features we have computed a high frequency sub-band to brighten the text part. Then K-means clustering is used for obtaining text pixels from the Standard Deviation (SD) of combined coefficient of wavelets and shearlets as well as the union of wavelets and shearlets features. Text parts are obtained by grouping neighboring regions based on geometric properties of the classified output frame of unsupervised K-means classification. The proposed method tested on a standard as well as newly collected database shows to be superior to some existing methods.

description: We analyze the numerical range of high-dimensional random matrices, obtaining limit results and corresponding quantitative estimates in the non-limit case. For a large class of random matrices their numerical range is shown to converge to a disc. In particular, numerical range of complex Ginibre matrix almost surely converges to the disk of radius $\sqrt{2}$. Since the spectrum of non-hermitian random matrices from the Ginibre ensemble lives asymptotically in a neighborhood of the unit disk, it follows that the outer belt of width $\sqrt{2}-1$ containing no eigenvalues can be seen as a quantification the non-normality of the complex Ginibre random matrix. We also show that the numerical range of upper triangular Gaussian matrices converges to the same disk of radius $\sqrt{2}$, while all eigenvalues are equal to zero and we prove that the operator norm of such matrices converges to $\sqrt{2e}$.

description: With the advent of high-performance computing, Bayesian methods are increasingly popular tools for the quantification of uncertainty throughout science and industry. Since these methods impact the making of sometimes critical decisions in increasingly complicated contexts, the sensitivity of their posterior conclusions with respect to the underlying models and prior beliefs is a pressing question for which there currently exist positive and negative results. We report new results suggesting that, although Bayesian methods are robust when the number of possible outcomes is finite or when only a finite number of marginals of the data-generating distribution are unknown, they could be generically brittle when applied to continuous systems (and their discretizations) with finite information on the data-generating distribution. If closeness is defined in terms of the total variation metric or the matching of a finite system of generalized moments, then (1) two practitioners who use arbitrarily close models and observe the same (possibly arbitrarily large amount of) data may reach opposite conclusions; and (2) any given prior and model can be slightly perturbed to achieve any desired posterior conclusions. The mechanism causing brittlenss/robustness suggests that learning and robustness are antagonistic requirements and raises the question of a missing stability condition for using Bayesian Inference in a continuous world under finite information.

Year: 2013

description: A multilayered plate theory which uses transverse shear warping functions issued from three-dimensional elasticity is presented. Two methods to obtain these transverse shear warping functions are detailed. The warping functions are issued from the variations of transverse shear stresses computed at special location points for a simply supported bending problem. The first method considers an exact 3D solution of the problem. The second method uses the solution provided by the model itself: the transverse shear stresses are computed by the integration of equilibrium equations. Hence, an iterative process is applied, the model being updated with the new warping functions, and so on. These two models are compared to other models and to analytical solutions for the bending of simply supported plates. Four different laminates and a sandwich are considered, length-to-thickness values varying from 2 to 100. An additional analytical solution that simulates the behavior of laminates under the plane stress hypothesis - which is retained by all presented models - shows that the iterative model almost gives the exact solution for all laminates and all length-to-thickness ratio values.

description: The Si(111) - 7 x 7 surface is one of the most interesting semiconductor surfaces because of its complex reconstruction and fascinating electronic properties. While it is known that the Si - 7 x 7 is a conducting surface, the exact surface conductivity has eluded consensus for decades as measured values differ by 7 orders of magnitude. Here we report a combined STM and transport measurement with ultra-high spatial resolution and minimal interaction with the sample, and quantitatively determine the intrinsic conductivity of the Si - 7 x 7 surface. This is made possible by the capability of measuring transport properties with or without a single atomic step between the measuring probes: we found that even a single step can reduce the surface conductivity by two orders of magnitude. Our first principles quantum transport calculations confirm and lend insight to the experimental observation.

description: We present results of targeted searches for signatures of non-radial oscillation modes (such as r- and g-modes) in neutron stars using {\it RXTE} data from several accreting millisecond X-ray pulsars (AMXPs). We search for potentially coherent signals in the neutron star rest frame by first removing the phase delays associated with the star's binary motion and computing FFT power spectra of continuous light curves with up to $2^{30}$ time bins. We search a range of frequencies in which both r- and g-modes are theoretically expected to reside. Using data from the discovery outburst of the 435 Hz pulsar XTE J1751$-$305 we find a single candidate, coherent oscillation with a frequency of $0.5727597 \times ν_{spin} = 249.332609$ Hz, and a fractional Fourier amplitude of $7.46 \times 10^{-4}$. We estimate the significance of this feature at the $1.6 \times 10^{-3}$ level, slightly better than a $3σ$ detection. We argue that possible mode identifications include rotationally-modified g-modes associated with either a helium-rich surface layer or a density discontinuity due to electron captures on hydrogen in the accreted ocean. Alternatively, the frequency could be identified with that of an inertial mode or an r-mode modified by the presence of a solid crust, however, the r-mode amplitude required to account for the observed modulation amplitude would induce a large spin-down rate inconsistent with the observed pulse timing measurements. For the AMXPs XTE J1814$-$338 and NGC 6440 X-2 we do not find any candidate oscillation signals, and we place upper limits on the fractional Fourier amplitude of any coherent oscillations in our frequency search range of $7.8\times 10^{-4}$ and $5.6 \times 10^{-3}$, respectively. We briefly discuss the prospects and sensitivity for similar searches with future, larger X-ray collecting area missions.

Advancements in Gaussian and Local Differential Privacy
Creators: Liu, Yi
Publisher: name: University of Alberta Library
Year: 2023

This thesis presents a comprehensive study of Gaussian Differential Privacy (GDP) and Local Differential Privacy (LDP), exploring their properties, relationships, and applications in developing novel algorithms and optimization methods for efficient and accurate privacy-preserving data analysis. In the first paper, we examine asymptotic properties of privacy profiles, develop a criterion for identifying GDP algorithms, propose an efficient method for narrowing down optimal privacy measurement values, and introduce a post-processing procedure for non-GDP algorithms. We also compare single-parameter privacy notions and demonstrate the advantages of our measurement process and the composition theorem of GDP. The second paper focuses on estimating population quantiles under LDP using binary inquiries, developing a self-normalizing, online algorithm with valid inference and optimality results for median estimation. The third paper introduces a novel algorithm for estimating Cumulative Distribution Function (CDF) curves under LDP by combining constrained isotonic estimation and binary inquiries, uncovering an unexpected connection to the current status problem in survival data analysis. We establish error bounds and computational efficiency for our estimator. Collectively, these papers contribute to the understanding and development of efficient, privacy-preserving mechanisms in GDP and LDP, providing valuable insights and practical tools for data analysts and privacy researchers, and advancing the state of the art in differential privacy research.

description: Tuza's Conjecture states that if a graph $G$ does not contain more than $k$ edge-disjoint triangles, then some set of at most $2k$ edges meets all triangles of $G$. We prove Tuza's Conjecture for all graphs $G$ having no subgraph with average degree at least $7$. As a key tool in the proof, we introduce a notion of reducible sets for Tuza's Conjecture; these are substructures which cannot occur in a minimal counterexample to Tuza's Conjecture. We also introduce weak König--Egerváry graphs, a generalization of the well-studied König--Egerváry graphs.

The influence of pks+ E. coli on the effectiveness of 5-FU  treatment in colorectal cancer cells
Creators: Ayyalasomayajula, Savita

Year: 2023

Colorectal cancer (CRC) is the fourth most commonly diagnosed cancer in Canada. There are two main pathways of genomic instability that lead to CRC: chromosomal instability (CIN), and microsatellite instability (MSI). 5-Fluorouracil (5-FU) is the most potent and safest anti-neoplastic drug that is widely used to treat CRC. 5-FU works by inhibiting thymidylate synthase, which results in disruptive DNA synthesis and causes cell death. A dysfunctional microbiome has long been associated with CRC development and progression. Higher incidence of cancer in the colon compared to elsewhere in the gastrointestinal tract can be attributed to a higher density of microorganisms and cancer-causing agents that disease causing microbes produce. Escherichia coli is more frequently associated with CRC biopsies, and specifically pks+ E. coli is associated with increased tumor growth in CRC mouse models. pks+ E. coli produces a genotoxin that is implicated to play a role in CRC as it induces double-strand DNA breaks that lead to mutations and thereby increase genomic instability. The aim of this research is to investigate how the presence of pks+ E. coli vs pks- E. coli alters the effect of 5-FU on the cell cycle, signalling and DNA damage in CRC cells with different predispositions to genomic instability. We find that pks+ E. coli by itself impacts CRC cells but in the presence of 5-FU, its effects are repressed. Therefore, it is likely that the presence of pks+ E. coli in a CRC patient does not affect the efficacy of 5-FU treatment. Our research aids in understanding 5-FU treatment in the context of host microbiota interactions which may help provide better treatment for CRC patients. It is crucial to continue to understand to what capacity themicrobiome impacts the efficacy of chemotherapeutics.
title: Holiday Lights Create Light Pollution and Become Ecological Trap for Eastern Fox Squirrels: Case Study on a University Campus

description: Ecological light pollution is now recognized as a significant source of ecosystem alteration. We documented that holiday lights are a seasonal source of light pollution that constitute an ecological trap for eastern fox squirrels (Sciurus niger). Texas A&M University-Kingsville (TAMUK) wildlife students surveyed a 2-km walking transect 5 times per month each month for the relative abundance and diel behavior of eastern fox squirrels and feral cats (Felis catus) on the TAMUK campus during 2018–2019. Eastern fox squirrels exhibited diurnal behaviors throughout the year but extended their foraging behavior nearly 4 hours after sunset with the addition of holiday lights. Feral cats and owls (Strigiformes) exhibited diurnal and nocturnal behaviors but conducted the majority of their hunting during crepuscular hours. We documented that monthly squirrel mortality increased 7-fold with the addition of holiday lights, possibly due to the extension of foraging time by squirrels. Although seasonal lighting is intended to be festive for humans, it can have negative consequences for eastern fox squirrels. Educating the public concerning the issue of light pollution on wildlife species is needed because the majority of the public appears unaware that bright lights can negatively alter wildlife behaviors. Reducing light intensity by either using less outdoor lights or perhaps using colored lights rather than clear white bulbs may lessen the negative effect on foraging behavior of squirrels.

description: This research proposal investigates the genotoxic implications of a vegetable extract containing heavy metals, along with the potential remedial effects of jamun seed extract on DNA damage. Using the Allium cepa root model and Comet Assay method, the study examines the extent of DNA damage in onion roots exposed to the vegetable extract. The project comprises four stages: sample acquisition and treatment, meticulous comet assay execution, lysis, electrophoresis, and staining procedures, culminating in data analysis. By comparing onion roots exposed to the vegetable extract alone and those co-exposed to the vegetable and jamun seed extracts, the study aims to understand genotoxicity and promote environmental awareness. This research contributes to our understanding of environmental pollutants' impact on DNA integrity, emphasizing the need for eco-conscious practices.
Spectroscopy of z ~ 7 candidate galaxies: Using Lyman-alpha to constrain the neutral fraction of hydrogen in the high-redshift universe

description: Following our previous spectroscopic observations of $z>7$ galaxies with Gemini/GNIRS and VLT/XSHOOTER, which targeted a total of 8 objects, we present here our results from a deeper and larger VLT/FORS2 spectroscopic sample of Wide Field Camera 3 selected $z>7$ candidate galaxies. With our FORS2 setup we cover the 737-1070nm wavelength range, enabling a search for Lyman-$α$ in the redshift range spanning 5.06 - 7.80. We target 22 $z$-band dropouts and find no evidence of Lyman-$α$ emission, with the exception of a tentative detection ($<5σ$, which is our adopted criterion for a secure detection) for one object. The upper limits on Lyman-$α$ flux and the broad-band magnitudes are used to constrain the rest-frame Equivalent Widths for this line emission. We analyse our FORS2 observations in combination with our previous GNIRS and XSHOOTER observations, and suggest that a simple model where the fraction of high rest-frame Equivalent Width emitters follows the trend seen at $z=3-6.5$ is inconsistent with our non-detections at $z\sim7.8$ at the 96\% confidence level. This may indicate that a significant neutral HI fraction in the intergalactic medium suppresses Lyman-$α$, with an estimated neutral fraction $χ_{HI}\sim0.5$, in agreement with other estimates.
