description:
The eastern Southern Alps are a seismically active region. Research has been conducted to identify seismically active faults, with the sources of several catastrophic earthquakes still unknown.

In this study, we conducted a paleoseismological investigation around the Fella-Sava Fault in the trijunction of Austria, Italy, and Slovenia, within the epicentral area of the destructive 1348 earthquake (MW 6.6-7.0). The Fella-Sava Fault is a ca. 100 km long, E-W- to WNW-ESE trending dextrally transpressive fault related to the Periadriatic fault system. Using digital elevation models (DEMs), we tried to identify direct evidence for surface rupturing earthquakes like fault scarps or offset geomorphic markers. Additionally, we put a special emphasis on sackungen. Sackungen are created by the gravitational collapse of mountain flanks, both aseismically and coseismically. Hillshades and aspect-maps derived from the DEMs proved suitable for mapping sackungen on a regional scale covering an area of ca. 1500 km2.

A systematic remote sensing-based mapping of sackungen (of which several were subsequently ground-proven) in an area 15 km to both sides of the western segment of the Fella-Sava Fault revealed their clustering within 5 km on either side of the fault. The sackungen correlate neither with lithology nor valley depth. A directional analysis shows that the preferred trend of the sackungen is parallel to the Fella-Sava Fault and doesn’t correlate with the distribution of regional slope orientations. Thus, we suspect that the higher number sackungen in proximity of the Fella-Sava-Fault provides geomorphological evidence for its postglacial seismic activity, including the 1348 earthquake.

description:
Throughout the past two decades, aquifer thermal energy storage (ATES) has grown increasingly into focus as a suitable geo-energy storage method. In this context, many carbonate aquifers are useable for storing and later retrieval of thermal energy due to their potential natural porosity and adequate permeability. However, numerous ATES projects suffer from operational and maintenance issues or failures. For instance, a reduction in reservoir permeability and clogging (caused by scaling, sintering, flocculation, and microbial growth) belong to the main threats to sustainable and reliable functioning.

In the BMBF-funded research project “UnClog-ATES”, both the aforementioned threats and their practical countermeasures (e.g., adding scaling inhibitors, acids, CO2) are thoroughly investigated using a combination of flow-through column and batch experiments. These experiments are temperature-controlled to simulate realistic ATES cycles of alternating heating and cooling while monitoring them continuously.

A critical point when assessing ATES systems specifically for carbonate aquifers is that significant inconsistencies exist regarding the kinetics and intensities of mineral dissolution/precipitation processes observed in the laboratory (using pure/synthetic minerals) and those observed in reality. This is because factors such as specific surface, dislodgement from equilibrium, presence of inhibitors as well as the rock’s chemical purity play important roles. For that reason, i.e., to represent natural ATES materials and to gain realistic reaction data, limestone from the Malm (Upper Jurassic), Germany (“Treuchtlinger Marmor”), is used for our experiments.

The overall project results aim towards gaining a variety of insights that are essential for planning, effective implementation, and sustainable operation of ATES in carbonate aquifers.

Ein Museum will eine Öffentlichkeit erreichen. Doch das ist leichter gesagt als getan, denn aus soziologischer Sicht zeigt sich die Öffentlichkeit nicht als monolithischer Block, sondern als ein Konglomerat aus sozialen Milieus, die Informationen sehr unterschiedlich aufnehmen und verarbeiten. Das Wahlkapfteam Barack Obamas z.B. war dementsprechend auf über 80 solcher ÖffentlichkeitEN eingestellt und sprach sie jeweils unterschiedlich an. Wie kann die Soziologie mit ihren Modellen von dem, was man gemeinhin "Gesellschaft" nennt der Wissenschaft, die genau weiß, "wie man mit dem Hammer philosopirt" (Nietzsche) ggf. dabei helfen, ihre Öffentlichkeiten zu erkennen und erfolgreich mit ihnen zu kommunzieren? Dieser Frage würde ich gerne in meinem Beitrag diskutieren.
Low-cost air quality sensors : from nuts & bolts to real world applications
Creators: name: Jain, Sakshi
Publisher: name: University of British Columbia

description: Recent advancements in low-cost sensor (LCS) technology have presented a new and affordable opportunity to understand and subsequently improve air quality. This thesis assessed the different stages of adoption and application of LCS technology, including calibrating the sensors, using sensors to build spatiotemporal pollutant maps, and using these maps to identify inequities in air pollution exposures. In Chapter 3, a general calibration method for commercially available low-cost PM₂.₅ sensors (PurpleAir/Plantower) was explored, such that the calibration models can be transferable to large geographical areas, especially in areas with limited monitoring. Inter-city models (e.g., trained in California and tested in India) built for regional concentrations were found to be effective in reducing errors by 30% in measurements. Chapter 4 used data from a network of 50 LCS deployed in Pittsburgh (Pennsylvania, USA) to build daily average land-use regression (LUR) and random-forests (LURF) spatiotemporal models for PM₂.₅, NO₂, and CO. The LURF models outperformed traditional regression techniques, with an increase in average externally cross-validated R² of 0.10-0.19. Models built after separating local contributions from the regional signal improved the R² by 0.14. In Chapter 5, the LURF models for PM₂.₅ were then used to build static (population spends 24 hours/day in a fixed residential area) and dynamic models (population moves between residential and commercial areas) and used to estimate variations in residents’ exposures to PM₂.₅ due to movement. The exposure estimates were consistently about 10% higher when the population spends more time in commercially-dense locations (dynamic model) vs residentially-dense locations (static model). Weekend concentrations were also 10% higher than weekday concentrations. Chapter 6 describes the deployment and analysis of data from a network of 11 LCS deployed in an environmental injustice neighborhood in Vancouver (British Columbia, Canada). PM₂.₅, NO₂, and O₃ concentrations were used to calculate cumulative hazard indices (CHIs) to identify hotspots within the neighborhood and to address the inequities in air pollution when compared to the Greater Vancouver region. Lastly, Chapter 7 summarizes the lessons learned from this thesis and provides insight into key design deployment considerations.

description:
Microbes, plants and other organisms actively shape the Earth surface by a variety of processes. Current research on modern systems suggests that biota has a significant impact on the mobility of trace elements and there is growing evidence that it may have done so since the dawn of life. The secretion of extracellular compounds that bind strongly to iron and other micronutrients are evolutionary traits that may, besides acquiring bio-essential trace metals, also have helped in tackling with the toxicity of certain heavy metals. An example of such compounds are siderophores, which are produced today by many different plants, microbes and fungi. Besides iron, they promote the (bio)availability of different highly-charged cations in the natural environment.

In paleoclimate studies, the redox-sensitive trace elements Ce and U are commonly used as geochemical proxies (e.g., Ce anomalies, Th-U ratios, stable U isotopes) for reconstructing atmospheric oxygen levels through time. We investigated the effect of siderophores on the mobilization of rare earth elements, Th and U (isotopes) from natural rocks under anoxic, hypoxic and oxic conditions. We show that experimental water–rock interaction with siderophores under strictly anoxic conditions produces positive Ce anomalies – a geochemical signal that is usually attributed to the presence of atmospheric oxygen. Siderophores also influence the Th-U signal, but do not induce a significant U stable isotope fractionation. Thus, oxygen-independent fractionation during geo–bio interaction may hold the potential to use certain trace elements as a bio-proxy in addition to their current use as a redox proxy.

description:
In this role-playing case study, students will learn about the HeLa cell line and its origins while examining multiple perspectives surrounding the cell line and its uses. The goal of this case study is for students to use guided questions to analyze different points of view such as researchers, family members, center directors, and contemporary scientists. Students will assume pre-designated roles and prepare short presentations for a panel of their peers to arrive at a decision regarding the further use of HeLa cells. This case may be completed in one 75-minute lesson or over a two-hour lab period. To accomplish this, the case study is divided into three parts including: 1) individual pre-class research and homework; 2) in-class group work and sharing of information among the class; and 3) an individual written post-class reflection. Ultimately, students are expected to consider and formulate an informed perspective to address the question: Should the continued use of HeLa cells be permitted in scientific research at our university?

description:
The width of fluvial valley-floors is a key parameter to quantifying the morphology of mountain regions. Valley-floor width is relevant to diverse fields including sedimentology, fluvial geomorphology, and archaeology. The width of valleys has been argued to depend on climatic and tectonic conditions, on the hydraulics and hydrology of the river channel that forms the valley, and on sediment supply from valley walls. Yet, so far, a physically-based model that can be used to predict valley width is lacking. Here, we derive such a model and test it against three different datasets. The model applies to valleys that are carved by a river migrating across the valley floor, and includes the effects of uplift and lateral hillslope sediment supply. Valley width is controlled mainly by the mobility-uplift number, which is the ratio between lateral channel mobility and uplift rate. At high values of the mobility-uplift number, the valley evolves to the channel-belt width, which is the width of the area actively reworked by the river in an unconfined setting. At low values of the mobility-uplift number, valley width corresponds to channel width. Between these limits, valley width is linked to the mobility-uplift number by a logarithmic function. We compare the model to independent data sets of valleys in experimental and natural uplifting landscapes and show that it closely predicts the first-order relationship between valley width and the mobility-uplift number.

description: This thesis conducts a critical discourse analysis of the Organization for Economic Co-operation and Development’s (OECD) perspectives on the role of Artificial Intelligence (AI) in education policy. The research focuses on the OECD’s AI and the Future of Skills (AIFS) volume, revealing how the organization envisions AI’s impact on workforce skills and its implications for global education systems. AI, exemplified by IBM’s Watson and OpenAI’s ChatGPT, has revolutionized various sectors, including education. The study traces the transformative influence of these AI models, specifically in higher education, from enhancing learning efficiencies to governing education sectors. The integration of AI in education, as reflected in the discourse and policies of international organizations like the OECD, underscore the constant evolution of AI and its increasing influence. The research utilizes Norman Fairclough’s work to carry out a Critical Discourse Analysis (CDA) of the AIFS document. The analysis aims to identify the underlying assumptions and ideologies that shape the OECD’s approach to AI in education policy. By examining the language, discourses, and structure of the document, insights are provided into the organization’s priorities, which are intended to shape the future of education across many nations. Moreover, the research considers broader contexts, such as educational neoliberalism, AI, and predictive forecasting in education. It critically examines the OECD’s priorities and discourses related to AI’s role and influence in education, particularly in anticipatory governance. The study is designed to provide valuable insights into the implications of the OECD’s approach to education in the age of AI. In conclusion, this study presents a comprehensive discourse analysis of the AIFS document’s language and structure, revealing the inherent ideologies related to AI in education policy. It underscores the critical role of international organizations like the OECD in shaping education policies in the AI era, contributing to the evolving discourse on AI, education policy, and the changing landscape of education governance.
Possible role of Eptifibatide drip in-patient with aneurysmal subarachnoid hemorrhage in vasospasm prevention
Creators: name: Zeenat Qureshi Stroke Institutes
Publisher: name: Zenodo
Year: 2023

description: Objective—Approximately 18,000 patients suffer from a subarachnoid hemorrhage (SAH) in the United States annually. SAH is a form of stroke and comprises 1%–5% of all strokes. Nearly 50% of all SAH cases end in fatality within 30 days of presentation; one of eight patients die before reaching a hospital. Those who survive often have neurological or cognitive impairment. Methods—This case report describes the course of two patients who presented to the emergency department with aneurismal subarachnoid hemorrhage and received external ventricular drainage and endovascular treatment of their aneurysm. Results—Both patients required treatment with Eptifibatide drip after endovascular approach and their SAH in the basal cisterns resolved by day 5. Neither patient developed signs of clinical or subclinical vasospasm. Comments—Eptifibatide drip facilitated resolution of the thick clot in the subarachnoid space early enough to eliminate the direct toxicity of oxyhemoglobin on the cerebral arteries and arachnoid granulations, thus preventing vasospasm and eliminating the necessity for a long-term shunt.

description:
Orogens in the Alpine-Himalayan collision zone (AHCZ) exhibit characteristic diffused seismicity compared to the stable continental interiors. Interestingly, they also have a thicker-than-average silica-rich upper crust and total crustal thickness, while their lithosphere thickness is similar to that of stable continental interiors (e.g., Tibet, Zagros). These observations provide a metric for the lithospheric-scale geological inheritance, the role of which we aim to understand in continental lithosphere dynamics over seismic and geologic timescales. To achieve this understanding, we use data-driven modelling to compute the present-day thermomechanical state of the AHCZ lithosphere.

Our results indicate the existence of a critical crustal thickness, which is thermodynamically controlled by the internal energy and chemical composition of the crust and is similar to the global average of continental crust thickness. Orogenic lithospheres with thicknesses above this critical value possess higher potential energy and are weakened by the internal energy from heat-producing elements, whereas continental interior lithospheres with thicknesses close to the critical crustal thickness are stronger. Weaker orogenic lithospheres respond via dissipating this energy in a diffused deformation mode, leading to zones of deformation in contrast to focused deformation at the plate-boundaries. The observed crustal differentiation in the AHCZ could be understood as perturbations to the critical crustal thickness caused by plate-boundary forces. The dynamic evolution of these perturbations indicates that the critical crustal thickness is a stable fixed-point attractor in the evolutionary phase-space.

description:
Seismic tomography provides important data to understand the physical properties (temperature, density) of the lithosphere and upper mantle. These physical properties are crucial for understanding e.g., strain localization, geothermal potential. However, interpreting tomography models in terms of composition and temperature conditions is highly complex and non-unique. There are mainly two approaches to interpreting seismic tomography models: empirical and thermodynamics-based. In the empirical approach, the tomography models are calibrated with respect to known temperature distributions, such as those derived from age-dependent oceanic lithospheric thickness or heat flow models or temperatures derived from mantle xenoliths in the continental regions. In contrast, the thermodynamics-based approach involves taking into account the composition of the minerals or deriving it from bulk-rock chemical composition using Gibbs-free energy minimization. Recently, a new approach has emerged that combines the second approach with geophysical (potential fields, topography) and seismological data (surface wave dispersion curves). However, this method assumes a steady-state temperature distribution, limiting its ability to infer the second-order temperature and density distribution. To address these challenges, a new thermodynamics-based conversion tool called V2RhoT_gibbs has been developed. This tool is based on open-source Python libraries and coupled with the Gibbs-free energy minimization algorithm Perple_X. It does not assume any thermal state and, using bulk-average chemical composition, derives the temperature and density distribution. Output from this tool could be easily used to incorporate e.g., as voxel in gravity field interpretations, or as lower temperature boundary condition to compute the thermal field.

description:
The geology of the Weser river terraces to the south of Hamelin is characterized by Quaternary sediments, consisting of thin alluvium and several meters of sand and gravels, overlying the seismic bedrock. We investigated a study area along the left Weser bank south of the village of Kirchohsen using different ambient seismic vibration techniques. Borehole logs show that the thickness of the Quaternary sediments varies from around 15 m to 33.5 m.

The fundamental frequency at a measurement point can be determined with the H/V method, which is based on the ratio between the horizontal and vertical spectra of the ambient seismic vibration signals. In the study area, the resonance frequency varies from 2.6 to 6.3 Hz, where low frequencies coincide with thicker Quaternary sediments and higher frequencies with thinner sedimentary layers. Assuming a continuity of the geological units, we can directly link the H/V frequencies to the sedimentary thickness and map the transition zone between the boreholes by H/V measurements along several profiles and additional individual points. We complement these H/V measurements by a new passive seismic array measurement and the reanalysis of older measurements in order to retrieve the dispersion curves of Rayleigh and Love waves and invert them for the shear-wave velocity profile.

The combination of the different data provides a detailed overview of the lateral changes within the shallow underground structure of the sedimentary layers of the study site.

description: Wound healing is a dynamic biological process achieved through four sequential, overlapping phases; hemostasis, inflammation, tissue proliferation and remodeling. For effective wound healing, all four phases must occur in the appropriate order and time frame. It is well accepted that the wound healing process becomes disrupted in the elderly, increasing the propensity of non-healing wound states that can lead to substantial patient morbidity and an enormous financial burden on healthcare systems. Estrogen deprivation in the elderly has been identified as the key driver of age-related delayed wound healing in both genders, with topical and systemic estrogen replacement reversing the detrimental effects of aging on wound repair. Evidence suggests estrogen deprivation may contribute to the development of chronic wound healing states in the elderly but research in this area is somewhat limited, warranting further investigations. Moreover, although the beneficial effects of estrogen on cutaneous healing have been widely explored, the development of estrogen-based treatments to enhance wound repair in the elderly have yet to be widely exploited. This review explores the critical role of estrogen in reversing age-related impaired healing and evaluates the prospect of developing more focused novel therapeutic strategies that enhance wound repair in the elderly via activation of specific estrogen signaling pathways in regenerating tissues, whilst leaving non-target tissues largely unaffected.

Data-driven detection and verification of replay attacks on industrial control systems
Creators: name: Gargoum, Sara
Publisher: name: University of British Columbia
Year: 2024

description: With the advent of Industrial Internet of Things and the push towards digitization, industrial control systems have undergone an increase in connectivity, which enables remote monitoring and control. This in turn has led to their increased vulnerability to several cyberattacks. These attacks can have severe consequences, including equipment damage, service disruption, and even compromising public safety. This thesis focuses on a certain type of cyberattacks, called replay attack. A replay attack involves capturing legitimate communication signals between components in an industrial control system and replaying it later to disrupt system operations or perform other attacks. This thesis presents a comprehensive study on the detection of replay attacks on sensor measurements in industrial control systems. Utilising the vast amount of operational data (i.e. sensor measurements) generated by industrial control systems, a novel data-driven two-stage detection and verification framework is proposed. The proposed framework combines statistical techniques, signal processing and deep learning to detect replay attacks on industrial control systems. The first stage of the detection method consists of continuous monitoring of sensor measurements by performing change-point detection based on the corresponding matrix profile. This stage provides an early indicator of a potential replay attack. The second stage provides a validation of whether the detected change-point is due to a replay attack or not. This stage consists of performing time-frequency analysis using short-time Fourier transform to generate a spectrogram, introducing spectral features to the time-series sensor measurements. Then, the spectrogram is split into image frames, creating spectro-temporal features. A Convolutional Long- Short Term Memory based autoencoder (ConvLSTM-AE) is designed to capture these spectro-temporal features in an unsupervised manner, where a replay attack is detected based on the reconstruction error. To evaluate the effectiveness of the proposed detection and verification framework, it is tested on different replay attack scenarios defined, in data generated using the Tennessee Eastman process benchmark simulation system/process.

description:
Indonesian laterite deposits are a major source of Ni and Co. Here, we present new geological data on the Sebuku laterites (SE Kalimantan, Indonesia), with a resource of ~390 Mt at 42.5 wt.% Fe, 0.9 wt.% Ni, and 0.15 wt.% Co. The deposits are mostly limonitic, oxide-dominated Fe-Ni-Co-rich horizons, which formed by weathering of Jurassic-Cretaceous ophiolitic units. Although the Fe ore has been mined since 2006, little mineralogical and geochemical data are available, which would allow optimizing beneficiation and recovery of Ni and Co.

Typical laterite profiles at Sebuku consist of: 1) weathered bedrock composed of serpentinized dunites and harzburgites overlain by 2) a 0.2-7 m-thick saprolite zone, 3) a 2-8.5 m-thick yellow limonite zone, and 4) a 1-3.5 m-thick red-limonite zone.

Preliminary XRF, XRD, and mineral liberation analysis (MLA) data show a decrease in Mg and Si and an increase in Fe moving upwards through the laterite profile, corresponding to a transition from silicate- to oxide-rich mineralogy. Oxides and (oxy)-hydroxides comprise goethite, maghemite, hematite, magnetite, chromium spinel, gibbsite/bayerite, and various Mn-minerals, whereas silicates consist of serpentine, chlorite, talc, quartz, pyroxene, olivine, and clay minerals. Ni is hosted by various minerals, which include goethite, Mn-oxides, serpentine, and clays, whereas Co is mainly hosted by Mn-oxides.

Mineral chemical analyses (EPMA) are planned to further understand critical metal variability and distribution within the host minerals and throughout the deposits. Our ultimate goal is to characterize and quantify the distribution of Ni and Co in order to develop more efficient beneficiation processes.

description:
Water stress is increasing in Northeast Germany due to climate change. New approaches for water management are needed to mitigate the impacts on the water system and water users. Therefore, our study deals with the development of a web-based toolbox for subsurface water storage with focus on the lower catchment of the river Spree in the federal state of Brandenburg.

Our approach is based on a systematic combination of site selection criteria and spatial data on land use, soil, groundwater and potential water sources. This will provide relevant information for the preliminary planning of managed groundwater recharge measures by authorities and water suppliers. Considering surpluses from runoff and surface waters, also caused by extreme weather events, suitable locations for surface-induced recharge will be identified.  

Supported by additional modelling-based indications for implementation, efficiency and costs, as well as simplified site selection through a query system, the toolbox will offer an initial knowledge for such planning considerations.

description:
Modern-style plate tectonics is characterized by the global operation of deep and cold subduction involving ultrahigh-pressure and blueschist-facies metamorphism. This is a common process since the Neoproterozoic, but a couple of studies indicate similar processes have been active in the Paleoproterozoic, at least on the local scale. Particularly conspicuous are extreme ultrahigh-pressure conditions of ~7 GPa at thermal gradients <150°C/GPa proposed for metamorphic rocks of the Nordre Strømfjord shear zone in the western part of the Paleoproterozoic Nagssugtoqidian Orogen of Greenland (Glassley et al., 2014). By acquiring a large dataset of heavy minerals (n = 52,130) and garnet major-element composition integrated with mineral inclusion analysis (n = 2,669) from modern sands representing fresh and naturally mixed erosional material from the metamorphic rocks, we here intensely screened the area for potential occurrences of ultrahigh-pressure rocks and put constraints on the metamorphic evolution. Apart from the absence of any indications pointing to ultrahigh-pressure and low-temperature/high-pressure metamorphism, the results are well in accordance with a common Paleoproterozoic subduction−collision metamorphic evolution along a Barrovian-type intermediate temperature/pressure gradient with a pressure peak at the amphibolite−granulite−eclogite-facies transition and a temperature peak at medium- to high-pressure granulite-facies conditions. This is in strong contrast to the proposed ultrahigh-pressure conditions and low geothermal gradients, and challenges the existence of a Paleoproterozoic modern-style plate-tectonic regime in western Greenland.

description:
The study aims to provide valuable insights into the dynamics of the interaction between carbonate melts and silicate wall-rocks during ascent and emplacement of carbonatitic intrusions. A specific focus is given to potential processes leading to rare earth element (REE) enrichment. It can be assumed that the interaction of silicate rocks with carbonate melt is diverse. Therefore, a study of granites interacting with a carbonatite melt was used to carefully assess the effects of a specific lithology.

The research centers the Bulhoek carbonatite complex, a bi-partite intrusion (Bulhoek North and South) situated in the eastern central region of the Bushveld Complex, approximately 35km west of Pilanesberg (South Africa), where it intruded the Nebo-granite (an integral part of the Bushveld Complex). The key characteristics of this intrusion are reflected by volcanic breccia, finitized Nebo-granite and beforsite (fine-grained magnesio-carbonatite) containing abundant apatite and strongly disaggregated granite xenoliths. Textural evaluation indicates that the element budget of the granites was resorbed by the carbonate melt. An integrated analytical approach, involving scanning electron microscopy (SEM), X-ray fluorescence (XRF), X-ray diffraction (XRD), and whole-rock analysis, is currently in progress to reveal the intricacies of the carbonate melt – granite interaction. While previous field studies have touched upon the fenitization of the Nebo-granite, a comprehensive understanding of the entire (and mutual) interaction remains a significant research gap. This study bridges this gap and will deepen our knowledge of carbonatite formation.

description: New non-volatile memory (NVM) technologies are projected to become the dominant type of main memory in the near future. They promise by the addressability, good read latencies, and significantly lower energy and higherdensity compared to DRAM. However, a key property of NVMs is the asymmetric read and write cost: write operations are much more expensive than reads regarding energy, bandwidth, and latency. This property contradicts fifty years of classic algorithms research that has focused on the setting in which reads and writes have similar cost, and poses the need to develop write-efficient algorithms that use fewer writes than the classic approaches. This thesis provides a comprehensive study of the design and analysisof write-efficient algorithms, which includes computational models, lower bounds, algorithms, and experimental validations. More specifically, this thesis first presents and studies several models that account for read-writeasymmetry in different settings (sequential, parallel, I/O models, etc.). Then, a number of lower bounds are shown, which indicate the hardness of asymptotically improving some classic algorithms under certain assumptions.The main contribution of this thesis consists of new write-efficient algorithms for fundamental algorithms in Computer Science, from basic algorithmic building blocks (sorting, reduce, filter, etc.), to graph algorithms ((bi)connectivity, shortest paths, MST, BFS, etc.), geometric algorithms anddata structures (convex hull, Delaunay triangulation, k-d trees, augmented trees, etc.), as well as many cache-oblivious algorithms for dynamic programming and linear algebra problems. The numbers of writes in all algorithmsstudied in this thesis are significantly reduced asymptotically. Furthermore, most of these algorithms are also highly parallel. Many techniques used to obtain these results are of independent interest, since they are applicable to many other problems outside those studied in this thesis, and lead to improved algorithms in the classic setting without read-write asymmetry. This thesis also proposes the first experimental framework to analyze the performance of write-efficient algorithms in practice, and conducts experiments on a variety of algorithms. The experimental results show the effectiveness of write-efficient algorithms, and suggest that the algorithms developed in this thesis may be of both theoretical and practical interest.
