The libertarian critique of this model, dominant within tech and philosophical communities, claims that the persuasive technologies of the attention economy infringe on the individual user’s autonomy and therefore the proposed solutions focus on safeguarding personal freedom through expanding individual control. While this push back is important, current societal debates on the ethics of persuasive technologies are informed by a particular understanding of attention, rarely posited explicitly yet assumed as the default. They share the same concept of attention, namely an individualistic and descriptive concept of attention that is a cognitive process, an expendable resource, something that one should control individually. We step away from a negative analysis in terms of external distractions and aim for positive answers, turning to Buddhist ethics to formulate a critique of persuasive technology from a genuinely ethical perspective. Buddhist ethics points at our attention’s inescapable ethical and ontological embeddedness. Attention as practice requires “the right effort” to distinguish desirable and undesirable states, the “right concentration” to stop the flow we are caught in, and the “right mindfulness” to fortify the ability to attend to the present situation and keep in mind a general sense of life’s direction. We offer input for further philosophical inquiry on attention as practice and attention ecology.

The optimal design parameters for ErCas12a editing in S. cerevisiae were defined as a 21-nt spacer flanked by 19 nt direct repeats expressed from either RNApolII or III promoters, achieving near 100% editing efficiencies in commonly targeted genomic locations. To be able to transfer the ErCas12a genome editing tool to different strain lineages, a transportable platform plasmid was constructed and evaluated for its genome editing efficiency. Using an identical crRNA expression design, the transportable ErCas12a genome editing tool showed lower efficiency when targeting the ADE2 gene. In contrast to genomic Ercas12a expression, episomal expression of Ercas12a decreases maximum specific growth rate on glucose, indicating ErCas12a toxicity at high expression levels. Moreover, ErCas12a processed a multispacer crRNA array using the RNA self-processing capability, which allowed for simultaneous editing of multiple chromosomal locations.

Extracellular deposits, including drusen and subretinal drusenoid deposits (SDD; also called reticular pseudodrusen), disrupt cone and rod photoreceptor functions and strongly confer risk for advanced disease. Due to the differential cholesterol composition of drusen and SDD, lipid transfer and cycling between photoreceptors and support cells are candidate dysregulated pathways leading to deposit formation. The current study explores this hypothesis through a comprehensive lipid compositional analysis of SDD. Methods: Histology and transmission electron microscopy were used to characterize the morphology of SDD. Highly sensitive tools of imaging mass spectrometry (IMS) and nano liquid chromatography tandem mass spectrometry (nLC-MS/MS) in positive and negative ion modes were used to spatially map and identify SDD lipids, respectively. An interpretable supervised machine learning approach was utilized to compare the lipid composition of SDD to regions of uninvolved retina across 1873 IMS features and to automatically discern candidate markers for SDD. Immunohistochemistry (IHC) was used to localize secretory phospholipase A2 group 5 (PLA2G5). Results: Among the 1873 detected features in IMS data, three lipid classes, including lysophosphatidylcholine (LysoPC), lysophosphatidylethanolamine (LysoPE) and lysophosphatidic acid (LysoPA) were observed nearly exclusively in SDD while presumed precursors, including phosphatidylcholine (PC), phosphatidylethanolamine (PE) and phosphatidic acid (PA) lipids were detected in SDD and adjacent photoreceptor outer segments. Molecular signals specific to SDD were found in central retina and elsewhere. IHC results indicated abundant PLA2G5 in photoreceptors and retinal pigment epithelium (RPE). Discussion: The abundance of lysolipids in SDD implicates lipid remodeling or degradation in deposit formation, consistent with ultrastructural evidence of electron dense lipid-containing structures distinct from photoreceptor outer segment disks and immunolocalization of secretory PLA2G5 in photoreceptors and RPE. Further studies are required to understand the role of lipid signals observed in and around SDD.","age-related macular degeneration; imaging mass spectrometry; interpretable supervised machine learning; lysolipid; retinal pigment epithelium; SHAP maps; subretinal drusenoid deposit","en","journal article","","","","","","","","","","","Team Raf Van de Plas","","",""

The algorithm is based on radar's kinematic measurements, providing fast and robust intention estimation for multiple targets. The core idea of the proposed algorithm is to build intention-specific features for each intention in advance and use them in actual drone surveillance situations. To effectively depict the trajectory characteristics of various intentions, the trajectory frequency is computed on multiple phase planes through Monte Carlo Simulations. Finally, a naive Bayes classifier is applied to integrate the trajectory likelihood in different phases and ultimately compute the intention likelihood of all intentions concerned. Numerical simulations for the three candidate intentions of image acquisition, smuggling, and kamikaze attack demonstrated the performance of the presented method. The simulation results show that one can estimate the true intention of a specific drone by comparing the value of each intention likelihood.","Bayes methods; pattern classification; radar target recognition; radar tracking; statistical analysis","en","journal article","","","","","","","","","","","Microwave Sensing, Signals & Systems","","",""

Objective: To ensure reliable and early detection of SRM, we wanted to automate the detection and analysis of SRM in experiments running on third-party experimentation platforms. Method: A set of Looker dashboards were built to facilitate self-serve SRM detection and root cause analysis. In addition, we added email and chat based alerting to pro-actively inform experimenters of SRM and guide them towards these dashboards when needed. Results: Several cases of SRM have been detected and experimenters have been warned. Bad decisions based on flawed data were avoided. We provide one such example as an illustration. Conclusions: SRM checks are relatively straightforward to automate and can be useful for data quality monitoring even for companies who rely on third-party experimentation platforms. Pro-active alerting—rather than passive reporting—can reduce time to detection and help non-experts avoid making decisions based on biased data.","Infrastructure; Data Quality; Trustworthiness; A/B Testing; Sample Ratio Mismatch; SRM; Online Controlled Experimentation","en","conference paper","Association for Computing Machinery (ACM)","","","","","","","","","","Software Engineering","","",""

The Republic of Georgia, the center of the Caucasus biodiversity hotspot, encompasses a geographically diverse landscape inhabited by a remarkable, endemic, and understudied flora and fauna under increasing threat from human activities. A wave of new and proposed dams for hydropower presents one of the most pressing challenges for freshwater biodiversity conservation in Georgia, a country where hydropower accounts for >90% of electricity. However, this situation remains largely unknown to the international scientific community and there is limited scientific information available about Georgia in the internationally indexed peer-reviewed literature. In this article, we describe the geography, politics, and freshwater biodiversity of rivers of Georgia, with a focus on fishes. We examine trends in hydropower development over the past century and identify four distinct periods: the pre-Soviet period (until 1921), the Soviet period (1921–1991), the 1990s immediately following Georgia's declaration of independence, and the 21st century. We explore the effects of existing and proposed dams on the connectivity of rivers of western Georgia and their potential consequences for conservation of diadromous, potamodromous, and resident fish. Using the Dendritic Connectivity Index (DCI) as an analytical lens, we found serial decreases in DCI values following different periods of hydropower development in the country. Finally, we offer four considerations for future research and conservation in light of ongoing hydropower development: i) expand biodiversity research and environmental monitoring, ii) assess and implement environmental flows for Georgian rivers, iii) implement strategic planning for new hydropower development, and iv) establish strict conservation areas for protection of endangered sturgeons.","Black Sea; Caucasus; Dams; Fish; Rivers; Sturgeon","en","journal article","","","","","","Accepted Author Manuscript","","2023-10-23","","","Water Resources","","",""

We partition the total uncertainty into the individual contributions caused by glacier models, general circulation models, RCPs, and natural variability. We find that emission scenario uncertainty is growing throughout the 21st century and is the largest source of uncertainty by 2100. The relative importance of glacier model uncertainty decreases over time, but it is the greatest source of uncertainty until the middle of this century.

In this ~40 y study of shallow reefs in the eastern Indian Ocean, we show that a rising relative sea level, currently estimated at ~11 mm y−1, has not only promoted coral cover but also has potential to limit damaging effects of thermally-induced bleaching. In 2010 the region experienced the most severe bleaching on record with corals subject to sea temperatures of >31 °C for 7 weeks. While the reef flats studied have a common aspect and are dominated by a similar suite of coral species, there was considerable spatial variation in their bleaching response which corresponded with reef-flat depth. Greatest loss of coral cover and community structure disruption occurred on the shallowest reef flats. Damage was less severe on the deepest reef flat where corals were subject to less aerial exposure, rapid flushing and longer submergence in turbid waters. Recovery of the most damaged sites took only ~8 y. While future trajectories of these resilient reefs will depend on sea-level anomalies, and frequency of extreme bleaching the positive role of rising sea level should not be under-estimated.","","en","journal article","","","","","","","","","","","Astrodynamics & Space Missions","","",""

In this paper, we report what has changed in the seven years since. The period has seen major platform evolution, with the mobile phone replacing the PC and laptop as the consumer terminal of choice, with Android replacing Windows, and with many services moving to the cloud. The use of social networks has become extremely widespread. The executive summary is that about half of all property crime, by volume and by value, is now online. We hypothesised in 2012 that this might be so; it is now established by multiple victimisation studies. Many cybercrime patterns appear to be fairly stable, but there are some interesting changes. Payment fraud, for example, has more than doubled in value but has fallen slightly as a proportion of payment value; the payment system has simply become bigger, and slightly more efficient. Several new cybercrimes are significant enough to mention, including business email compromise and crimes involving cryptocurrencies. The move to the cloud means that system misconfiguration may now be responsible for as many breaches as phishing. Some companies have suffered large losses as a side-effect of denial-of-service worms released by state actors, such as NotPetya; we have to take a view on whether they count as cybercrime. The infrastructure supporting cybercrime, such as botnets, continues to evolve, and specific crimes such as premium-rate phone scams have evolved some interesting variants. The overall picture is the same as in 2012: traditional offences that are now technically ‘computer
crimes’ such as tax and welfare fraud cost the typical citizen in the low hundreds of Euros/dollars a year; payment frauds and similar offences, where the modus operandi has been completely changed by computers, cost in the tens; while the new computer crimes cost in the tens of cents. Defending against the platforms used to support the latter two types of crime cost citizens in the tens of dollars. Our conclusions remain broadly the same as in 2012: it would be economically rational to spend less in anticipation of cybercrime (on antivirus, firewalls, etc.) and more on response. We are particularly bad at prosecuting criminals who operate infrastructure that other wrongdoers exploit. Given the growing realisation among policymakers that crime hasn’t been falling over the past decade, merely moving online, we might reasonably hope for better funded and coordinated law-enforcement action.","","en","conference paper","","","","","","","","","","","Organisation & Governance","","",""

To estimate reliable flood extents, we need to accurately model the complex wave processes that occur across the reef. To explore the multivariate nature of coastal flooding, we rely on a climate emulator that accounts for climate variability and simulates time series of all the variables involved. Due to the computational constraints to numerically simulate thousands of events, we explore the feasibility of using a recently developed tool, the HyCreWW (Hybrid Coral Reef Wave and Water level) meta-model to estimate wave run-up and flooding extents.

(TU Delft Mechanical Engineering)","Metrikine, A. (mentor); Tsouvalas, A. (graduation committee); van Dalen, K.N. (graduation committee); Winkes, Jasper (mentor); Delft University of Technology (degree granting institution)","2017","In the 26 years since the first offshore wind farm was installed in Vindeby, Denmark, the offshore wind industry has undergone remarkable growth. Recently, this growth has accelerated, advancing farms rapidly into deeper water and utilizing larger turbines. As offshore wind farm developers continue to look towards heavier, higher capacity turbines, and harsher sites, improving cost-effectiveness will rely increasingly on support structure optimization. Monopile foundations remain the preferred option, but the “XL” monopiles required in deeper water are sensitive to wave-induced fatigue loads and exceed the weight capacity of many installation vessels.
The goal of the Hybrid Monopile support structure, is to provide a cost-effective alternative to the monopile in water depths greater than 30 meters. By providing an open structure in the key wave loading area of the water column, wave-induced fatigue damage can be reduced, allowing for a thinner monopile shell and a substantially lighter support structure. Design of the Hybrid Monopile began with the optimization of the brace member length and diameter for a specific location and turbine in the North Sea. Computations. were carried out using a Matlab-based model in which the structure is represented as a discretized Euler-Bernoulli beam.
Extreme load cases were applied in a static analysis to ensure that selected dimensions are able to resist buckling of either the monopile shell, or the brace members. An accompanying finite-element model of the structure was used to verify that the selected brace dimensions were sufficient under extreme loads. To estimate the fatigue life of the monopile shell, and the brace members, wave loads were handled in the frequency domain and wind loads in the time domain. Damage equivalent loads (DELs) for each were then combined using quadratic superposition. Wind and wave roses for the selected site were used in the fatigue analysis to capture the effects of misaligned wind-wave cases on the calculated fatigue life. In this design phase, the Hybrid Monopile was shown to experience sixty percent less wave-induced fatigue damage than the traditional monopile.
This baseline version of the design was then modified for 256 different combinations of water depth, turbine size, wave climate, and monopile diameter, to demonstrate the versatility of the concept and identify the design drivers. During the design process, the Hybrid Monopile was updated by altering the monopile shell thickness, brace diameter, and brace length. In each case, a traditional monopile was also designed in parallel, to serve as a basis for comparison. Optimization of each configuration was based on an iterative series of design checks during which the variable design dimensions were increased or decreased based on the structure natural frequency, response to an extreme load, or expected fatigue life at one of the critical locations; the mudline and the individual brace cross sections.
Results of the iteration showed that in more than 3/4 of the test cases, which covered water depths from 30-60 meters, and turbine sizes of 8-20 MW, a Hybrid Monopile could be established that offered lower structure weight and improved fatigue performance at an equal or reduced cost compared to a traditional monopile. Viable configurations showed average weight and cost reductions of 27% and 17% respectively. These results were used to establish a limited number of standardized Hybrid Monopile classes, which could be mass produced and assigned to a wind farm, based on only the water depth and turbine size. Looking forward, further work is required to determine the optimum connection detail at the brace-monopile interface, and to assess the fatigue risk at that junction.

Based on Malawian prices, the cost of sanitizing 1 m3 of faecal sludge was estimated to be 32 for lactic acid fermentation, 20 for urea treatment and 12 for hydrated lime treatment.","ammonia; emergency sanitation; Escherichia coli; excreta; faecal sludge; lactic acid; lime; urea","en","journal article","MDPI","","","","","","","","Civil Engineering and Geosciences","Water Management","","","",""

The event was driven by a fast-moving coronal mass ejection and despite being a moderate storm with a minimum Dst near ?50 nT, the event exhibited elevated thermospheric density and surges of traveling atmospheric disturbances (TADs) more typically seen during major storms. The Thermosphere-Ionosphere-Mesosphere-Electrodynamics General Circulation Model (TIMEGCM) was used to assess how these features were generated and developed during the storm. The model simulations gave rise to TADs that were highly nonuniform with strong latitude and longitude/local time dependence. The TAD phase speeds ranged from 640?m/s to 780?m/s at 400?km and were ~5% lower at 300?km and approximately 10–15% lower at 200?km. In the lower thermosphere around 100?km, the TAD signatures were nearly unrecognizable due to much stronger influence of upward propagating atmospheric tides. The thermosphere simulation results were compared to observations available from the Gravity Field and Steady-State Ocean Circulation Explorer (GOCE), CHAllenging Minisatellite Payload (CHAMP) and Gravity Recovery and Climate Experiment (GRACE) satellites. Comparison with GOCE data shows that the TIMEGCM reproduced the cross-track winds over the polar region very well. The model-data comparison also revealed some differences, specifically, the simulations underestimated neutral mass density in the upper thermosphere above ~300?km and overestimated the storm recovery tome by 6 h. These discrepancies indicate that some heating or circulation dynamics and potentially cooling processes are not fully represented in the simulations, and also that updates to some parameterization schemes in the TIMEGCM are warranted.","thermospheric storm; ionospheric storm; TADs; neutral winds","en","journal article","American Geophysical Union","","","","","","","2015-06-09","Aerospace Engineering","Space Engineering","","","",""

These coastal areas are typically of low elevation and relief,making land and infrastructure highly susceptible to inundation by storm surge and waves. These verity of this threat is exacerbated by sea level rise and a possible increase in storm frequency and strength due to climate change. Although hard protection structures such as levees and flood walls reduce flood risk, these structures may fail when storm conditions exceed the design threshold. There is a general consensus that wetlands, which often serve as transition zones between open water and dry land, could act as buffers and reduce storm surge and propagatingwaves substantially before they encounter coastal development. Unfortunately, the capability of wetlands to serve as protection during extreme storms is not understood fully or well documented; furthermore, water level and wave height reductions by vegetation are studied only in low-energy environments. Nonetheless, these studies present methods to quantify vegetation induced wave attenuation for both modeling and design. This technical note focuses on the damping of propagating water waves by vegetation, but also discusses surge reduction briefly.Although waves may be encountered in freshwater environments(e.g., boat wakes, lake fetch,flood waves, etc.), this review focuses on coastal vegetation and resultant effects on flood and storm damage reduction.","wave dissipation; vegetation; near shore effect; energy dissipation","en","report","USACE","","","","","","","","","","","","",""

In addition, enhanced vertical permeability has been identified as a common feature. We investigate the effects of vertical anisotropy of a fault zone on the distribution of hydraulic head within the fault, using an analytic solution. We conclude that anisotropy ratios greater than 100 result in nearly hydrostatic conditions within the fault zone, despite the existence of significant vertical flow rates. Under these conditions, the Dupuit approximation is adequate for predicting the flow from one side of the fault to the other. We then present explicit analytical solutions to problems of steady groundwater flow in a multiaquifer system cut by a single vertical fault. The fault is linear and of negligible width, is infinite in length, and acts as a conduit for vertical fluid flow. The fault may act as a leaky barrier to horizontal flow normal to the fault, as a conduit to horizontal flow tangential to the fault, or a combination of both. Examples are presented that highlight the effects of enhanced vertical permeability of a fault on aquifer interaction in a multiaquifer system.

The main interpretation challenge is to invert the measured data, solving for the true resistivity values in each zone of a reservoir. Inversion is not always an easy task because logging tools measure a bulk average resistivity. Thus reservoir heterogeneity can have a considerable effect on inversion accuracy. Two of the most significant problems are effects caused by regions adjacent to zones of interest and resistivity anisotropy (variation of resistivity with direction). The growing use of directional drilling has recently focused attention on the magnitude of anisotropy effect. Therefore this thesis concentrates on the new area of inversion in anisotropic reservoirs. The geologic origins of anisotropy are examined, and a parametric inversion method is introduced for obtaining directional resistivity values in layered media. Background is also provided on practical modeling methods for use in inversion, and on the physics of various resistivity loggingtools.","","en","doctoral thesis","Delft University Press","","","","","","","","Information Systems and Technology","","","","",""
