Mechanism of deformation in graphene during out-of-plane high-rate loading
Creators: name: Cordova, Landon
Publisher: name: No Publisher Supplied
Year: 2022

description: There is a growing interest in the strain engineering of 2D materials for applications in semiconductor devices. Free standing graphene has been shown to undergo plastic bending during high-rate out-of-plane loading. However, there is currently very limited theory for the mechanisms of plasticity in bending mode deformation of 2D materials.Here, molecular dynamics studies are presented in which 5-7 dislocation dipoles are introduced randomly into suspended graphene sheets, which form out-of-plane ripples as a stress relieving mechanism. The sheet then undergoes high-rate loading from a cylindrical indenter, and residual plastic bending is measured. Correlations identified from these results indicate that higher strain rates and dislocation densities result in increased plasticity. Changes due to indentation in the out-of-plane rippled structure are quantified using a ridge and valley detection algorithm, which suggests that the out-of-plane ripple geometry may influence plastic bending, though, no strong correlations are found between the measured ripple geometry metrics and plastic bending, indicating a non-trivial relationship between the out-of-plane geometry and plastic bending.Further molecular dynamics studies investigate the snap-through buckling behavior of single 5-7 dislocation dipole ripples as they are forced through the plane of the sheet. The energy barrier of this event is measured, and qualitative analysis of the ripple snap-through indicates that this is a kinematically driven process. A wave dynamics model describing snap-through during indentation is proposed.

description: CUORE is a cryogenic experiment searching primarily for neutrinoless double decay in $^{130}$Te. It will begin data-taking operations in 2016. To monitor the cryostat and detector during commissioning and data taking, we have designed and developed Slow Monitoring systems. In addition to real-time systems using LabVIEW, we have an alarm, analysis, and archiving website that uses MongoDB, AngularJS, and Bootstrap software. These modern, state of the art software packages make the monitoring system transparent, easily maintainable, and accessible on many platforms including mobile devices.

description: The rise in global mean temperature is an incomplete description of warming. For many purposes, including agriculture and human life, temperature extremes may be more important than temperature means and changes in local extremes may be more important than mean global changes. We define a nonparametric statistic to describe extreme temperature behavior by quantifying the frequency of local daily all-time highs and lows, normalized by their frequency in the null hypothesis of no climate change. We average this metric over 1218 weather stations in the 48 contiguous United States, and find significantly fewer all-time lows than for the null hypothesis of unchanging climate. Record highs, by contrast, exhibit no significant trend. The metric is evaluated by Monte Carlo simulation for stationary and warming temperature distributions, permitting comparison of the statistics of historic temperature records with those of modeled behavior.

description: Dynamical equations in generalized hydrodynamics (GHD), a hydrodynamic theory for integrable quantum systems at the Euler scale, take a rather simple form, even though an infinite number of conserved charges are taken into account. We show a remarkable quantum-classical equivalence: we demonstrate the equivalence between the equations of GHD, and the Euler-scale hydrodynamic equations of a new family of classical gases which generalize the gas of hard rods. In this family, the "quasi-particles", upon colliding, jump forward or backward by a distance that depends on their velocities, generalizing the jump forward by the rods' length of the fixed-velocity tracer upon elastic collision of two hard rods. Such velocity-dependent position shifts are characteristics of classical soliton scattering. The emerging hydrodynamics of a quantum integrable model is therefore that of the classical gas of its solitons. This provides a "molecular dynamics" for GHD which is numerically efficient and flexible. This is directly applicable, for instance, to the study of inhomogeneous dynamics in integrable quantum chains and in the Lieb-Liniger model realized in cold-atom experiments.

Real existing ideals: East Germany and the socialist imaginary 1945-1991
Creators: name: Petrusek, Alexander
Publisher: name: No Publisher Supplied
Year: 2022

description: This dissertation examines how socialist ideals, drawn from a broader socialist imaginary, guided activist practices in the German Democratic Republic (GDR/East Germany). The GDR was expressly founded as a socialist society constantly transforming itself for the better, ultimately to reach a utopian state of being, or communism. Activists within, outside of, and opposed to the ruling Socialist Unity Party (SED) all sought to practice ambitious ideals to continually transform society for the better. Activists developed and understood these ideal practice through a distinctly socialist imaginary, encompassing social-historical understandings, or “background,” that provided the GDR with its discourses, epistemologies, and habitus. This socialist imaginary also determined what was considered normal or normative, as well as prohibited, fantastical, or impossible. The socialist imaginary was thus the source of a East Germans’ sense of reality and its ideals, and guided those activists seeking to preserve or change the status quo. Ultimately this work challenges existing scholarship that sees socialism as an illegitimate and imposed ideology, finding instead that socialist ideal practices were a key driver of social transformation in East German history.This work focuses on five specific case studies of ideal practice in this broader development of East German and socialist history. The first three chapters trace party and party-affiliated activists’ attempts to build socialism in the GDR from 1945 until the early 1970s. They examine ideals of antifascist democracy, socialist consciousness, and socialism itself as a self-regulating metasystem through their contingent and contested practice. The latter two chapters trace a gradual shift of ideal authority from the party-state to an emerging civil movement. This movement, beginning with environmental activists active in the semi-autonomous Protestant Church in the late 1970s, eventually expanded their criticisms of a static and repressive party-state into ideals of, and demands for, a sustainable, direct democratic, and for many, still socialist GDR. This movement then sought to practice these ideals during the revolution of 1989, and enshrine them in a new constitution for the GDR and, possibly, a unified Germany.

description: The stellar initial mass function (IMF) describes the distribution of stellar masses when a population of stars first forms. It is a particularly crucial property connecting many different phenomena within a galaxy. Defining the IMF of a galaxy is therefore critical for helping us to understand how galaxies evolve over cosmic time. However, defining the IMF has been the subject of vigorous debate over the past few decades. Recent evidence from early-type galaxies which appear to become more dwarf star rich as galactic mass increases supports a variable rather than universal IMF. With improvements in technology, the question of whether the IMF varies spatially within galaxies has also begun to be investigated, with no clear result as yet. This thesis presents preliminary results from the Fornax3Dsurvey using the MUSE integral field spectrograph. Two techniques for finding the IMF are compared here for the lenticular galaxy FCC167: full spectral fitting, and a more constrained approach focusing on a few key features. While the two methods agree reasonably well on radial variations for the age and abundance parameters in common, the derived IMF shape and its variation within the galaxy differ.

description: To further explore the molecular mechanism of triterpenoid biosynthesis and acquire high-value strain of Sanghuangporus baumii, the Agrobacterium tumefaciens-mediated transformation (ATMT) system was studied. The key triterpenoid biosynthesis-associated gene isopentenyl diphosphate isomerase (IDI) was transformed into S. baumii by ATMT system. Then, the qRT-PCR technique was used to analyze gene transcript level, and the widely targeted metabolomics was used to investigate individual triterpenoid content. Total triterpenoid content and anti-oxidant activity were determined by spectrophotometer. In this study, we for the first time established an efficient ATMT system and transferred the IDI gene into S. baumii. Relative to the wild-type (WT) strain, the IDI-transformant (IT) strain showed significantly higher transcript levels of IDI and total triterpenoid content. We then investigated individual triterpenoids in S. baumii, which led to the identification of 10 distinct triterpenoids. The contents of individual triterpenoids produced by the IT2 strain were 1.76–10.03 times higher than those produced by the WT strain. The triterpenoid production showed a significant positive correlation with the IDI gene expression. Besides, IT2 strain showed better anti-oxidant activity. The findings provide valuable information about the biosynthetic pathway of triterpenoids and provide a strategy for cultivating high-value S. baumii strains.

description: MapReduce provides a parallel and scalable programming model for data-intensive business and scientific applications. MapReduce and its de facto open source project, called Hadoop, support parallel processing on large datasets with capabilities including automatic data partitioning and distribution, load balancing, and fault tolerance management. Meanwhile, scientific workflow management systems, e.g., Kepler, Taverna, Triana, and Pegasus, have demonstrated their ability to help domain scientists solve scientific problems by synthesizing different data and computing resources. By integrating Hadoop with Kepler, we provide an easy-to-use architecture that facilitates users to compose and execute MapReduce applications in Kepler scientific workflows. Our implementation demonstrates that many characteristics of scientific workflow management systems, e.g., graphical user interface and component reuse and sharing, are very complementary to those of MapReduce. Using the presented Hadoop components in Kepler, scientists can easily utilize MapReduce in their domain-specific problems and connect them with other tasks in a workflow through the Kepler graphical user interface. We validate the feasibility of our approach via a word count use case.

description: The mechanism of ion bombardment induced magnetic patterning of exchange bias layer systems for creating engineered magnetic stray field landscapes is still unclear. We compare results from vectorial magneto-optic Kerr effect measurements to a recently proposed model with time dependent rotatable magnetic anisotropy. Results show massive reduction of rotational magnetic anisotropy compared to all other magnetic anisotropies. We disprove the assumption of comparable weakening of all magnetic anisotropies and show that ion bombardment mainly influences smaller grains in the antiferromagnet.

description: Due to a history of malpractice in archaeology, minimally and non-destructive investigative techniques are necessary to protect precious artefacts and mummified remains for the future. Using a combination of established and novel techniques, X-ray computed tomography (CT) and neutron CT, allowed for non-destructive study of IA.2402, an unusual Egyptian votive mummy of unknown age and provenance. These imaging methods revealed a partial skeleton of a small, juvenile cat. Use of both techniques allows for dual contrast and complementary study of bones, soft tissue, and textile components. Neutron CT, never before applied to archaeometric studies of mummified remains, provided valuable insight into wrapping techniques used in the mummification process. Pigment analysis was performed for coloured markings on the wrappings, using a scanning electron microscope and Raman spectroscopy, to determine their composition and authenticity. Protein extraction and analysis was attempted, however was inconclusive of species due to the decayed state of remains. Radiocarbon dates were acquired, and provided quantitative results to compare with morphological observations and conclusions based on partiality of the contents. All techniques were employed to better define and profile the specimen, within its historical context, while causing as little physical disruption as possible.

description: This paper describes the design and the performance of the timing detector developed by the TOTEM Collaboration for the Roman Pots (RPs) to measure the Time-Of-Flight (TOF) of the protons produced in central diffractive interactions at the LHC. The measurement of the TOF of the protons allows the determination of the longitudinal position of the proton interaction vertex and its association with one of the vertices reconstructed by the CMS detectors. The TOF detector is based on single crystal Chemical Vapor Deposition (scCVD) diamond plates and is designed to measure the protons TOF with about 50 ps time precision. This upgrade to the TOTEM apparatus will be used in the LHC run 2 and will tag the central diffractive events up to an interaction pileup of about 1. A dedicated fast and low noise electronics for the signal amplification has been developed. The digitization of the diamond signal is performed by sampling the waveform. After introducing the physics studies that will most profit from the addition of these new detectors, we discuss in detail the optimization and the performance of the first TOF detector installed in the LHC in November 2015.

description: The 21st Dynasty was a time of intrigue and change, not only politically but economically and archaeologically. Funerary practices, including the production of coffins and their decoration altered producing some of the most beautiful and densely decorated material. The coffin set of Meruah NMR.27 housed in the Nicholson Museum, Sydney University is one such example. Through an analysis of the decoration on the coffin set of Meruah an understanding is gained on the relationship between the content of the scenes and their placement on the coffin. This thesis will explore the symbolism and meaning tied to the decoration in order to understand why the ancient Egyptians decorated their coffins in this manner.

description: The sensitivity of molecular dynamics on changes in the potential energy function plays an important role in understanding the dynamics and function of complex molecules.We present a method to obtain path ensemble averages of a perturbed dynamics from a set of paths generated by a reference dynamics. It is based on the concept of path probability measure and the Girsanov theorem, a result from stochastic analysis to estimate a change of measure of a path ensemble. Since Markov state models (MSM) of the molecular dynamics can be formulated as a combined phase-space and path ensemble average, the method can be extended toreweight MSMs by combining it with a reweighting of the Boltzmann distribution. We demonstrate how to efficiently implement the Girsanov reweighting in a molecular dynamics simulation program by calculating parts of the reweighting factor "on the fly" during the simulation, and we benchmark the method on test systems ranging from a two-dimensional diffusion process to an artificial many-body system and alanine dipeptide and valine dipeptide in implicit and explicit water. The method can be used to study the sensitivity of molecular dynamics on external perturbations as well as to reweight trajectories generated by enhanced sampling schemes to the original dynamics.

description: End-user-programmable business-level services composition is an effective way to build virtual organizations of individual applications in a just-intime manner. Challenging issues include how to model business-level services so that the end users can understand and compose them; how to associate businesslevel services to underlying Web services. This paper presents a service virtualization approach called VINCA Virualization to supporting the abstraction, transformation, binding and execution of Web services by end users. Four key mechanisms of VINCA Virualization namely semantics annotation, services aggregation, virtualization operation and services convergence are discussed in details. VINCA Virualization has been implemented and its application in a real-world project is illustrated. The paper concludes with a comparative study with other related works.
Polarization of gamma-ray burst afterglows in the synchrotron self-Compton process from a highly relativistic jet

description: Linear polarization have been observed in both the prompt phase and afterglow of some bright gamma-ray bursts (GRBs). Polarization in the prompt phase spans a wide range, and may be as high as $\gtrsim 50\%$. In the afterglow phase, however, it is usually below $10\%$. According to the standard fireball model, GRBs are produced by synchrotron radiation and Compton scattering process in a highly relativistic jet ejected from the central engine. It is widely accepted that prompt emissions occur in the internal shock when shells with different velocities collide with each other, and the magnetic field advected by the jet from the central engine can be ordered in large scale. On the other hand, afterglows are often assumed to occur in the external shock when the jet collides with interstellar medium, and the magnetic field produced by the shock through, e.g. Weibel instability, is possibly random. In this paper, we calculate the polarization properties of the synchrotron self-Compton process from a highly relativistic jet, in which the magnetic field is randomly distributed in the shock plane. We also consider the generalized situation where a uniform magnetic component perpendicular to the shock plane is superposed on the random magnetic component. We show that, the polarization is hardly to be larger than $10\%$ if the seed electrons are isotropic in the jet frame. This may account for the observed upper limit of polarization in the afterglow phase of GRBs. In addition, if the random and uniform magnetic components decay with time in different speeds, then the polarization angle may change $90^{\circ}$ duration the temporal evolution.

description: While colour centres in diamond have numerous exciting room-temperature applications, it remains important to be able to study and control their properties at cryogenic temperatures where crystal phonon activity is suppressed. A cryogenic confocal microscope has been developed using galvanometer beam scanning and a closed-cycle helium cold-finger cryostat. This has required novel software control, and a new set of confocal scanning modules have been developed for the Qudi experimental control software suite. Testing has shown remarkable galvanometer repeatability and stability over many hours. The high scanning speed and low thermal drift are outstanding. Combined with the low level of vibrations and high temperature stability of the cryostat, this allows precise measurements over periods of many days. A series of group grown nanodiamond samples were characterised at close to 10 K with photoluminescence measurements. Inhomogeneous broadening is characterised and thermal broadening of the spectra as temperature varies allowed for estimates of the nanodiamond temperatures. Active investigation of more home grown samples is ongoing, including looking for germanium vacancy sites, examining variation between nanodiamond samples and looking at the cooling performance of nanodiamond samples in this cryostat.

Palm trees, xanax, and dank memes: vaporwave’s nostalgia play
Creators: name: Mahood, Max Alexander James
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: This thesis studies the online multimedia genre of vaporwave (alternatively spelled ‘vapourwave’) as a vehicle of self-expression for certain members of the millennial generation. The genre is the latest milestone in a tradition of appropriation art from a musical perspective, as well as a visual one. Vaporwave’s practitioners appropriate and recycle material to create works which evoke nostalgia for the recent past, especially the aesthetics of the late 1980s and early 1990s, early internet art and computerised graphics from the same period. The musical aspect of the genre follows similar themes, and samples obscure or forgotten music and sounds (such as TV commercials or computer operating system sounds, for example). The central question which describes the thesis is, ‘To What Extent Do Millennial Worldviews Inform Vaporwave?’ The thesis answers this question not only by understanding millennial worldviews, but also framing that understanding around vaporwave and its nostalgic tendencies. To do this, numerous media theories (such as the concept of ‘media nostalgia’ and ‘hauntology’, terms credited to Katharina Niemeyer and Jacques Derrida respectively ) will be employed to develop an insight into how vaporwave and its millennial audience views past media objects as a source for the genre and its artistic inspiration. Furthermore, the thesis considers the impact that historical events has had on vaporwave’s outlook and that promotes desire of the millennial generation to ‘return to a better time’ (such as the 1990s, when members of the generation were children) through vaporwave’s nostalgia play.

description: Everything in the world is being connected, and things are becoming interactive. The future of the interactive world depends on the future Internet of Things (IoT). Software-defined networking (SDN) technology, a new paradigm in the networking area, can be useful in creating an IoT because it can handle interactivity by controlling physical devices, transmission of data among them, and data acquisition. However, digital signage can be one of the promising technologies in this era of technology that is progressing toward the interactive world, connecting users to the IoT network through device-to-device communication technology. This article illustrates a novel prototype that is mainly focused on a smart digital signage system comprised of software-defined IoT (SD-IoT) and invisible image sensor communication technology. We have proposed an SDN scheme with a view to initiating its flexibility and compatibility for an IoT network-based smart digital signage system. The idea of invisible communication can make the users of the technology trendier to it, and the usage of unused resources such as images and videos can be ensured. In addition, this communication has paved the way for interactivity between the user and digital signage, where the digital signage and the camera of a smartphone can be operated as a transmitter and a receiver, respectively. The proposed scheme might be applicable to real-world applications because SDN has the flexibility to adapt with the alteration of network status without any hardware modifications while displays and smartphones are available everywhere. A performance analysis of this system showed the advantages of an SD-IoT network over an Internet protocol-based IoT network considering a queuing analysis for a dynamic link allocation process in the case of user access to the IoT network.

description: Nitrogen (N) is the most critical plant nutrient. Maize has a high nitrogen demand. Low maize (Zea mays L.), yields in smallholder farms of Malawi, the country’s staple, is attributable to declining N fertility aggravated by the ever increasing price of fertilizer. Little effort has been made to establish the best nitrogen rate in a maizecowpea and maize-bean intercrop under variable soil conditions as a way of improving production, and was the objective of the current study. Field experiments were conducted at Chitedze Agricultural Research Station in Lilongwe and Makoka Agricultural Research Station in Zomba during the 2016/17 growing season. A split plot layout in a randomized complete block design, with three replicates was used. The main plots were; sole maize, sole bean, sole cowpea, bean/maize and cowpea/maize intercrop systems. The sub plots were N fertilizer rates (0, 52.5, 78.75 and 105 kg N ha-1 ), applied as urea. The data collected was subjected to analysis of variance using SAS software version 9.3 (SAS Institute Inc.) at P<0.05. Means were separated using Duncan Multiple Range (DMRT) test at 95% significance level. The results showed that application of N increased maize N uptake and grain yield. NUE however decreased with increasing N fertilizer rate.

description: A new branch of black hole solutions occurs along with the standard Schwarzschild branch in $n$-dimensional extensions of general relativity including terms quadratic in the Ricci tensor. The standard and new branches cross at a point determined by a static negative-eigenvalue eigenfunction of the Lichnerowicz operator, analogous to the Gross-Perry-Yaffe eigenfunction for the Schwarzschild solution in standard $n=4$ dimensional general relativity. This static eigenfunction has two rôles: both as a perturbation away from Schwarzschild along the new black-hole branch and also as a threshold unstable mode lying at the edge of a domain of Gregory-Laflamme-type instability of the Schwarzschild solution for small-radius black holes. A thermodynamic analogy with the Gubser and Mitra conjecture on the relation between quantum thermodynamic and classical dynamical instabilities leads to a suggestion that there may be a switch of stability properties between the old and new black-hole branches for small black holes with radii below the branch crossing point.

description: Bismuth Selenide (Bi$_{2}$Se$_{3}$) is a topological insulator (TI) with a structure consisting of stacked quintuple layers. Single crystal surfaces are commonly prepared by mechanical cleaving. This work explores the use of low energy Ar$^{+}$ ion bombardment and annealing (IBA) as an alternative method to produce reproducible and stable Bi$_{2}$Se$_{3}$ surfaces under ultra-high vacuum (UHV). It is found that a well-ordered surface can be prepared by a single cycle of 1 keV Ar$^{+}$ ion bombardment and 30 min of annealing. Low energy electron diffraction (LEED) and detailed low energy ion scattering (LEIS) measurements show no differences between IBA-prepared surfaces and those prepared by $\textit{in situ}$ cleaving in UHV. Analysis of the LEED patterns shows that the optimal annealing temperature is 450°C. Angular LEIS scans reveal the formation of surface Se vacancies when the annealing temperature exceeds 520°C.

description: As an enhancement of cellular networks, the future-generation 5G network can be considered an ultra-high-speed technology. The proposed 5G network might include all types of advanced dominant technologies to provide remarkable services. Consequently, new architectures and service management schemes for different applications of the emerging technologies need to be recommended to solve issues related to data traffic capacity, high data rate, and reliability for ensuring QoS. Cloud computing, Internet of things (IoT), and software-defined networking (SDN) have become some of the core technologies for the 5G network. Cloud-based services provide flexible and efficient solutions for information and communications technology by reducing the cost of investing in and managing information technology infrastructure. In terms of functionality, SDN is a promising architecture that decouples control planes and data planes to support programmability, adaptability, and flexibility in ever-changing network architectures. However, IoT combines cloud computing and SDN to achieve greater productivity for evolving technologies in 5G by facilitating interaction between the physical and human world. The major objective of this study provides a lawless vision on comprehensive works related to enabling technologies for the next generation of mobile systems and networks, mainly focusing on 5G mobile communications.

description: We propose a model of an adaptive network of spiking neurons that gives rise to a hypernetwork of its dynamic states at the upper level of description. Left to itself, the network exhibits a sequence of transient clustering which relates to a traffic in the hypernetwork in the form of a random walk. Receiving inputs the system is able to generate reproducible sequences corresponding to stimulus-specific paths in the hypernetwork. We illustrate these basic notions by a simple network of discrete-time spiking neurons together with its FPGA realization and analyze their properties.

Infant-directed speech of Australian English mothers and fathers: a high and variable pitch with a more breathy and less creaky voice quality
Creators: name: Tobin, Elise Juliet
Publisher: name: Macquarie University
Year: 2022
Subjects: Other education not elsewhere classified

description: Adults spontaneously speak differently to infants, in Infant-Directed Speech (IDS), compared to Adult Directed Speech (ADS). Key acoustic characteristics of IDS are the increased utterance-level pitch measures, specifically an increased mean or median, minimum, maximum and range. Lesser-studied characteristics of IDS include increased variability in utterance-level F0 across an interaction and a breathier voice quality. Moreover, while there is an abundance of literature on mothers' IDS, there is still limited understanding of fathers' IDS. To address these gaps in the literature, this study compared utterance-level pitch properties, across-conversation pitch variability and voice quality of Australian English mothers' and fathers' IDS, compared to ADS. The final study sample consisted of eight Australian English mother-father dyads and their infant (6-12 months). IDS was elicited from parent-infant dyads during play with toys, and ADS was elicited from mother-father dyads during a play task. The IDS and ADS elicitation tasks were closely matched, maintaining consistency in interlocutor familiarity and the type of activity engaged in by dyads, thus isolating the effect of the infants' presence on both mothers' and fathers' speech. Audio recordings were segmented into utterances and perceptually coded for the presence of whispered speech, and breathy and creaky voice. Utterance-level pitch measures, the standard deviation of utterance-level F0, and the prevalence of voice quality types, were compared across parent genders and registers. Both mothers and fathers increased all utterance-level pitch measures as well as acrossconversation pitch variability in IDS, compared to ADS. Both parent genders, and especially mothers, decreased their creakiness and increased their breathiness in IDS, compared to ADS. These results are discussed in relation to methodological choices, including measures of pitch and voice quality, automated coding in acoustic analyses and task-design considerations -- abstract.

description: The Geostationary Ocean Color Imager (GOCI) Yonsei aerosol retrieval (YAER) version 1 algorithm was developed to retrieve hourly aerosol optical depth at 550 nm (AOD) and other subsidiary aerosol optical properties over East Asia. The GOCI YAER AOD had accuracy comparable to ground-based and other satellite-based observations but still had errors because of uncertainties in surface reflectance and simple cloud masking. In addition, near-real-time (NRT) processing was not possible because a monthly database for each year encompassing the day of retrieval was required for the determination of surface reflectance. This study describes the improved GOCI YAER algorithm version 2 (V2) for NRT processing with improved accuracy based on updates to the cloud-masking and surface-reflectance calculations using a multi-year Rayleigh-corrected reflectance and wind speed database, and inversion channels for surface conditions. The improved GOCI AOD τG is closer to that of the Moderate Resolution Imaging Spectroradiometer (MODIS) and Visible Infrared Imaging Radiometer Suite (VIIRS) AOD than was the case for AOD from the YAER V1 algorithm. The V2 τG has a lower median bias and higher ratio within the MODIS expected error range (0.60 for land and 0.71 for ocean) compared with V1 (0.49 for land and 0.62 for ocean) in a validation test against Aerosol Robotic Network (AERONET) AOD τA from 2011 to 2016. A validation using the Sun-Sky Radiometer Observation Network (SONET) over China shows similar results. The bias of error (τG−τA) is within −0.1 and 0.1, and it is a function of AERONET AOD and Ångström exponent (AE), scattering angle, normalized difference vegetation index (NDVI), cloud fraction and homogeneity of retrieved AOD, and observation time, month, and year. In addition, the diagnostic and prognostic expected error (PEE) of τG are estimated. The estimated PEE of GOCI V2 AOD is well correlated with the actual error over East Asia, and the GOCI V2 AOD over South Korea has a higher ratio within PEE than that over China and Japan.

description: According to theory and empirical research, traumatic experiences early in life can lead to greater impact on an individual than traumas occurring in adulthood. Traumatic events among young people are common with one in every four children living in a developing country being likely to experience a traumatic event by the time they are 18 years old. However, due to a variety of social, economic and environmental disadvantages, children from developing countries are at even greater risk of trauma exposure. The research in this thesis comprised samples of children and adolescents from Bangladesh, a developing world country that differs from the developed world not only on socio-economic grounds but also in cultural factors including language, traditions and religions.
