title: Economics of Land Use Planning--Utah Recreational Subdivisions, 1962-72
Creators: name: Mac Pherson, Donald William (Sandy)
Publisher: name: Utah State University
Year: 1974

description: Economic and environmental inventory and evaluation were made of Utah recreational subdivisions filed with the state from 1962 through 1972. Major data were collected from standard subdivision questionnaires, filed by developers with Utah Real Estate Division, Department of Business Regulation. Study included 62,716 lots, 238,004 acres, and a value, in terms of developers' projected gross sales, of $211,836,550 in 1972 dollars.
Description of Utah recreational urbanization included: community services such as water supply and sanitation, drainage and flooding, fire protection, roads, and schools; developer sales inducements, improvement costs, and selling costs; subdivision layout characteristics, locations, magnitude, value, and buildout rates; and lot owner improvements. Data included documentation of subdivisions by year, by county, and by county and year, in terms of number of subdivisions, number of lots, number of acres, average size in acres, average price per acre, and total value. Number of lots in each county was compared with county populations, populations changes, households, and household changes. Development locations were documented on a state map using composite computer mapping techniques.
Developer questionnaires revealed economic and environmental impacts of recreational urbanization. Economic impact study included property tax assessments and revenues, state filing fees and administrative costs, and projected demand on community services. Environmental impact discussed included soil erosion, sedimentation, and preemption of public land use. Locational analysis was made with respect to natural environment: national forests, parks, monuments, and recreational areas. Political, social, and cultural impacts were also discussed.
Special problems of long term leases of state School lands to recreational subdividers was studied. A case study in Iron County documented subsidization of California and Nevada ownership of Southern Utah mountain property through differential assessment.
Effects of existing tax and fee control techniques upon recreational development were identified and assessed. Examination was made of state and local laws and regulations and their enforcement as they relate to development impacts on state and local economic and natural environments, with comparison of Utah with California and Colorado.
Theory of environmental economics was applied to land use planning, control, and management. Economic alternatives to alleviating problems of recreational urbanization were presented, with special attention to problems of: speculation; demand on community services; tax inequities, negative economic and environmental impacts; an internalizing, for the public sector, external costs of private development. Composite computer mapping was illustrated as a land use planning tool in solving "fit" between human settlements and the natural environment.

description: We consider the operator product expansions for unitarity fermions. We compute the dynamic structure factor S(q,w) at large frequency and wavenumber away from the one-particle peak. The overall normalization of S(q,w) is determined by Tan's contact parameter, and the dependence on q and w is obtained in closed analytic form. We also find energy deposited into the system by small, rapid variations of the inverse scattering length.

description: The ubiquity of edge devices has led to a growing amount of unlabeled data produced at the edge. Deep learning models deployed on edge devices are required to learn from these unlabeled data to continuously improve accuracy. Self-supervised representation learning has achieved promising performances using centralized unlabeled data. However, the increasing awareness of privacy protection limits centralizing the distributed unlabeled image data on edge devices. While federated learning has been widely adopted to enable distributed machine learning with privacy preservation, without a data selection method to efficiently select streaming data, the traditional federated learning framework fails to handle these huge amounts of decentralized unlabeled data with limited storage resources on edge. To address these challenges, we propose a Self-supervised On-device Federated learning framework with coreset selection, which we call SOFed, to automatically select a coreset that consists of the most representative samples into the replay buffer on each device. It preserves data privacy as each client does not share raw data while learning good visual representations. Experiments demonstrate the effectiveness and significance of the proposed method in visual representation learning.

description: In topological data analysis (TDA), persistence diagrams have been a succesful tool. To compare them, Wasserstein and Bottleneck distances are commonly used. We address the shortcomings of these metrics and show a way to investigate them in a systematic way by introducing bottleneck profiles. This leads to a notion of discrete Prokhorov metrics for persistence diagrams as a generalization of the Bottleneck distance. They satisfy a stability result and bounds with respect to Wasserstein metrics. We provide algorithms to compute the newly introduced quantities and end with an discussion about experiments.

description: Automatic speech recognition research focuses on training and evaluating on static datasets. Yet, as speech models are increasingly deployed on personal devices, such models encounter user-specific distributional shifts. To simulate this real-world scenario, we introduce LibriContinual, a continual learning benchmark for speaker-specific domain adaptation derived from LibriVox audiobooks, with data corresponding to 118 individual speakers and 6 train splits per speaker of different sizes. Additionally, current speech recognition models and continual learning algorithms are not optimized to be compute-efficient. We adapt a general-purpose training algorithm NetAug for ASR and create a novel Conformer variant called the DisConformer (Disentangled Conformer). This algorithm produces ASR models consisting of a frozen 'core' network for general-purpose use and several tunable 'augment' networks for speaker-specific tuning. Using such models, we propose a novel compute-efficient continual learning algorithm called DisentangledCL. Our experiments show that the DisConformer models significantly outperform baselines on general ASR i.e. LibriSpeech (15.58% rel. WER on test-other). On speaker-specific LibriContinual they significantly outperform trainable-parameter-matched baselines (by 20.65% rel. WER on test) and even match fully finetuned baselines in some settings.

description: The addition of transition metals (TM) to III-V semiconductors radically changes their electronic, magnetic and structural properties. In contrast to the conventional semiconductor alloys, the lattice parameter in magnetic semiconductor alloys, including the ones with diluted concentration (the diluted magnetic semiconductors - DMS), cannot be determined uniquely from the composition. By using first-principles calculations, we find a direct correlation between the magnetic moment and the anion-TM bond lengths. We derive a simple formula that determines the lattice parameter of a particular magnetic semiconductor by considering both the composition and magnetic moment. The formula makes accurate predictions of the lattice parameter behavior of AlMnN, AlCrN, GaMnN, GaCrN, GaCrAs and GaMnAs alloys. This new dependence can explain some of the hitherto puzzling experimentally observed anomalies, as well as, stimulate other kind of theoretical and experimental investigations.

title: Population Limitation of Jackrabbits: an Examination of the Food Hypothesis
Creators: name: Clark, William R.
Publisher: name: Utah State University
Year: 1979

description: The study was conducted to examine the importance of forage resources in limiting peak population density of black-tailed jackrabbits (Lepus californicus). The research design combined field studies of jackrabbit diet and vegetation impact with computer simulation of herbivore nutrition and population dynamics. The relationships between available forage, dietary intake, energy and protein balance and population changes were compared for high and low population density. Hypotheses tested were : (1) Dietary composition is unaffected by availability above 10 kg/ha; (2) Jackrabbits do not require more forage than is available at high population densities; (3) Dietary composition is not significantly different at high and low densities; (4) Dietary composition is not significantly different between sexes; (5) Nutritional balance of lactating females is not significantly altered at high density; and (6) Nutritional balance of females entering the breeding season is not significantly altered at high density.
The field studies were designed to measure dietary preference by the jackrabbits, the availability of herbage, and utilization of selected plant species. Jackrabbits ate nearly all forage types available but primarily consumed dominant shrubs in fall and winter, suffrute scents in fall and winter, grasses in spring and summer, and forbs in summer. There was no significant difference between dietary composition or preference rating among density periods or sexes. Dietary percentage of preferred forage species was directly related to availability above 10 kg/ha. Jackrabbits removed an average of 30 to 40 percent of individual plants of Kochia americana, but only browsed on 5 toll percent of all available plants. Total removal of Kochiastanding crop averaged only 3.7 percent.
The model used in the simulation studies incorporated relationships involving existence, activity and production (growth, gestation and lactation) requirements to estimate forage requirements. Intake and requirements affect energy and protein balance which are related to body weight changes and production. Model mortality rates are modified by nutritional deficiency as a fraction of the requirements.
The following conclusions resulted from model simulations. Forage requirements are less than 1 percent of available forage, even at high population density. Nutritional balance of lactating females was unaffected by observed diets or population density. Nutritional balance of females entering the breeding season is unaffected by diet but may be affected by early breeding date or large litter size. Individual nutritional response and its interaction with food does not cause significant change in population mortality rates. Nutritional deficiency may contribute to mortality, particularly during lactation or winter periods, but these effects are independent of population density.

description: Given a holomorphic submersion of reduced complex spaces, we prove that the basic Oka property of the submersion implies the parametric Oka property. This generalizes the corresponding result for complex manifolds (F. Forstneric, Oka Manifolds, C. R. Acad. Sci. Paris, Ser. I, 347 (2009) 1017-1020). It follows that a stratified elliptic (or subelliptic) holomorphic submersion, or a stratified holomorphic fiber bundle whose fibers are Oka manifolds, enjoys the parametric Oka property. As an application we give a parametric version of the factorization theorem due to Ivarsson and Kutzschebauch (A solution of Gromov's Vaserstein problem, C. R. Acad. Sci. Paris, Ser. I 346 (2008) 1239-1243) for holomorphic maps from finite dimensional reduced Stein spaces to the special linear group SL_n(C).

description: In zukünftigen Fusionskraftwerken wird für den Einsatz des „Direct Internal Recycling“ Konzepts (DIR) die Abtrennung von Wasserstoff aus Gasmischungen bei niedrigem Druck in einem Verfahrensschritt benötigt. Nach dem derzeitigen Stand der Technik ist dies bisher nicht möglich. Der Effekt der Superpermeation ist in der Lage die Anforderungen für diesen Prozess zu erfüllen. Darauf basierend wird in der vorliegenden Arbeit eine Prozesseinheit, die Metallfolienpumpe (MFP), entwickelt. Um die Bedeutung der dargelegten Entwicklung aufzuzeigen, werden zunächst die Vorteile des DIR herausgearbeitet. Es ist derzeit keine andere Technologie bekannt, die eine solch bedeutende Verbesserung des Brennstoffkreislaufs von zukünftigen Fusionsreaktoren ermöglicht. Die charakteristische Funktionsweise der MFP wird ausgehend von den grundlegenden physikalischen Abläufen erklärt. Die beeinflussenden Materialeigenschaften werden dabei beschrieben und die relevanten Literaturdaten dargestellt. Basierend auf den erläuterten Vorgängen wird ein dimensionsloses Modell abgeleitet, das die dominierenden Prozesse in der Metallfolie, dem Kernelement der MFP, beschreibt. Aus diesem Modell werden die Limitierungen für die möglichen Folienmaterialien abgeleitet. Mit Hilfe der dargestellten Materialeigenschaften wird die dimensionslose Beschreibung in quantifizierte Aussagen für einzelne Materialien umgewandelt. Auf diese Weise wird gezeigt, dass sich die Metalle Niob und Vanadium am besten für Metallfolienpumpen in Fusionskraftwerken eignen. Die Bildung von Wasserstoffbläschen wird als wichtige Materiallimitierung aufgezeigt und begründet. Im Rahmen dieser Arbeit werden zwei experimentelle Einrichtungen genutzt. Dabei wird eine im Rahmen dieser Arbeiten entworfen, gebaut, in Betrieb genommen und eingesetzt. Die Superpermeation wird erfolgreich mit mehreren Metallfolienmaterialien und Energiequellen für Wasserstoff demonstriert. Diese Energiequellen sind neben der Metallfolie das zweite bedeutende Element einer MFP. Ihr Einsatz ist stark vom gewünschten Saugdruck der Pumpe abhängig. Mehrere Vorhersagen des dimensionslosen Modells werden experimentell nachgewiesen. Basierend auf den experimentellen Ergebnissen wird ein klarer Entwicklungspfad aufgezeigt. Dabei werden die offenen Forschungsfragen und ihr Einfluss diskutiert.

description: A global uniform carbon price would be economically efficient and at the same time avoid ‘carbon-leakage’. Still, it will affect the competitiveness of specific industries, economic activity and employment across countries. This paper assesses short-term economic shocks following the introduction of a global carbon price that would be in line with the Paris Agreement. Based on the World Input-Output Database (WIOD), we trace the carbon content of final output through global supply chains. This allows us to estimate how prices of the final output would react to the introduction of a global carbon price. We find that impacts on industrial competitiveness are highly heterogeneous across regions and economic sectors. The competitive position of Brazil, Japan, the USA and advanced economies of the EU is likely to improve, whereas industries and labor markets in newly industrializing Asian economies as well as Eastern Europe are likely to experience substantial adverse impacts. © 2019 The Author(s)

description: Ferromagnets are known to support spin-polarized currents that control various spin-dependent transport phenomena useful for spintronics. On the contrary, fully compensated antiferromagnets are expected to support only globally spin-neutral currents. Here, we demonstrate that these globally spin-neutral currents can represent the Néel spin currents, i.e. staggered spin currents flowing through different magnetic sublattices. The Néel spin currents emerge in antiferromagnets with strong intra-sublattice coupling (hopping) and drive the spin-dependent transport phenomena such as tunneling magnetoresistance (TMR) and spin-transfer torque (STT) in antiferromagnetic tunnel junctions (AFMTJs). Using RuO$_{2}$ and Fe$_{4}$GeTe$_{2}$ as representative antiferromagnets, we predict that the Néel spin currents with a strong staggered spin-polarization produce a sizable field-like STT capable of the deterministic switching of the Néel vector in the associated AFMTJs. Our work uncovers the previously unexplored potential of fully compensated antiferromagnets and paves a new route to realize the efficient writing and reading of information for antiferromagnetic spintronics.

description: Background— Turner syndrome is a genetic disorder caused by partial or complete monosomy of the X chromosome.Although a few cases of ischemic stroke have been reported in Turner syndrome, but isolated intracranial arterydissection has not yet been reported. We report a case of a patient with Turner syndrome with middle cerebral arterydissection and, present the clinical and radiological features.Case Description— A 34-year-old woman with Turner syndrome and diabetes mellitus was referred to ourhospital with symptoms of left hemiparesis post appendectomy. Magnetic resonance imaging outside hospitalshowed diffusion restriction in the right middle cerebral artery territory with magnetic resonance angiography (MRA)identifying a right MCA occlusion. Digital subtraction angiography revealed a M1 segment occlusion. Mechanicalthrombectomy of the right M1 segment was performed but a triangular flow-limiting stenosis for an underlyingdissection. Intracranial stent placement was then performed with successful reperfusion.Conclusions— Ischemic stroke in Turner syndrome can occur due to dissection of intracranial arteries and mayrequire additional stent placement during mechanical thrombectomy. Further studies are required to investigate themechanism for predisposition for dissection in Turner syndrome
title: Naturally Occurring Organic Compounds Found in Hyrum Reservoir, Utah

Publisher: name: Utah State University
Year: 1977

description: Methods of collecting, concentrating, separating, and identifying organic compounds in natural water systems are presented. These methods were applied to a eutrophic reservoir (Hyrum Reservoir, Utah) and resulted in the identification of the following 27 volatile, organic compounds:
Alcohols: methanol, ethanol, 1-propanol, isopropyl alcohol, 1-butanol, 2-butanol, isobutyl alcohol, tert-butyl alcohol, 1-pentanol, 2-methyl-l-butanol, methyl-1- butanol, 3-methyl-2-butanol, 2-methyl-2-butanol, 2-methyl-3-buten-2-ol, 1-penten-3-ol, 2-methyl-2-pentanol
Ketones: acetone, methyl ethyl ketone, 4-methyl-3-penten-2-one
Aldehydes: acetaldehyde, propanal, 2-buten-1-al
Others: acetonitrile, ethyl acetate, pyridine, 3-methylpyridine, diethyl ether
The concentration level of the following 13 compounds was established in the reservoir from October 1974 to January 1976:
Alcohols: methanol, ethanol, propanol, isopropyl alcohol, 1-butanol, isobutyl alcohol, tert-butyl alcohol 2-methyl-2-butanol, 2-methyl-3-buten-2-ol
Ketones: acetone, methyl ethyl ketone
Others: acetonitrile, acetaldehyde
The highest concentrations of organics were found in the late summer or early fall as the bloom of Aphanizomenon flos-aquae died and the level of bacterial fermentation increased. Other sources of organic compounds in the reservoir (besides fermentation) included compounds (acetonitrile and ethanol) at least partially produced by active algal growth and associated bacteria. Melting snowpack and mountain streams that feed the reservoir also contained organic compounds similar to those found in the reservoir, however at lower levels.
Most of the compounds at low concentrations had no effect on the growth of certain algae tested, however there was some indication that certain organics may have increased the net growth of Aphanizomenon flos-aquae.

description: A scheme is discussed for measuring Nth-order coherences of two orthogonally polarized light fields in a single spatial mode at very limited experimental cost. To implement the scheme, the only measurements needed are the Nth-order intensity moments after the light beam has passed through two quarter-wave plates, one half-wave plate, and a polarizing beam splitter for specific settings of the wave plates. It is shown that this method can be applied for arbitrarily large N. A set of explicit values is given for the settings of the wave plates, constituting an optimal measurement of the Nth-order coherences for any N. For Fock states the method introduced here corresponds to a full state tomography. Applications of the scheme to systems other than polarization optics are discussed.

Regression Diagnostics meets Forecast Evaluation: Conditional Calibration, Reliability Diagrams, and Coefficient of Determination

name: Resin, Johannes
Publisher: name: arXiv
Year: 2021
Subjects: subject: Methodology (stat.ME)
subject: FOS: Computer and information sciences

description: Model diagnostics and forecast evaluation are two sides of the same coin. A common principle is that fitted or predicted distributions ought to be calibrated or reliable, ideally in the sense of auto-calibration, where the outcome is a random draw from the posited distribution. For binary responses, this is the universal concept of reliability. For real-valued outcomes, a general theory of calibration has been elusive, despite a recent surge of interest in distributional regression and machine learning. We develop a framework rooted in probability theory, which gives rise to hierarchies of calibration, and applies to both predictive distributions and stand-alone point forecasts. In a nutshell, a prediction - distributional or single-valued - is conditionally T-calibrated if it can be taken at face value in terms of the functional T. Whenever T is defined via an identification function - as in the cases of threshold (non) exceedance probabilities, quantiles, expectiles, and moments - auto-calibration implies T-calibration. We introduce population versions of T-reliability diagrams and revisit a score decomposition into measures of miscalibration (MCB), discrimination (DSC), and uncertainty (UNC). In empirical settings, stable and efficient estimators of T-reliability diagrams and score components arise via nonparametric isotonic regression and the pool-adjacent-violators algorithm. For in-sample model diagnostics, we propose a universal coefficient of determination, $$\text{R}^\ast = \frac{\text{DSC}-\text{MCB}}{\text{UNC}},$$ that nests and reinterprets the classical $\text{R}^2$ in least squares (mean) regression and its natural analogue $\text{R}^1$ in quantile regression, yet applies to T-regression in general, with MCB $\geq 0$, DSC $\geq 0$, and $\text{R}^\ast \in [0,1]$ under modest conditions.

description: We apply the Hierarchical Autoregressive Neural (HAN) network sampling algorithm to the two-dimensional $Q$-state Potts model and perform simulations around the phase transition at $Q=12$. We quantify the performance of the approach in the vicinity of the first-order phase transition and compare it with that of the Wolff cluster algorithm. We find a significant improvement as far as the statistical uncertainty is concerned at a similar numerical effort. In order to efficiently train large neural networks we introduce the technique of pre-training. It allows to train some neural networks using smaller system sizes and then employing them as starting configurations for larger system sizes. This is possible due to the recursive construction of our hierarchical approach. Our results serve as a demonstration of the performance of the hierarchical approach for systems exhibiting bimodal distributions. Additionally, we provide estimates of the free energy and entropy in the vicinity of the phase transition with statistical uncertainties of the order of $10^{-7}$ for the former and $10^{-3}$ for the latter based on a statistics of $10^6$ configurations.

title: Effects of Low-Level Chronic Radiation on Plant Nuclear Parameters as Related to Successional Patterns
Creators: name: Rechel, Eric A.
Publisher: name: Utah State University
Year: 1977

description: A major issue facing nuclear power stations is how to effectively deal with radioactive waste. This waste, as it comes from a reactor, is emitting large quantities of ionizing radiation which is usually confined. Another form of radioactive wastes is the mill tailings from uranium processing plants. These tailings are sites characterized by low-level chronic radiation.
The mill tailings of the Vitro Chemical Plant, in Salt Lake City, Utah, have been a point of radionuclide concentration and environmental contamination for 20 years. These tailings may adversely affect both surrounding ecosystems and any biological systems seeking to become established on the site. To test the potential hazard of this site to the succession of plant species I examined the interphase chromosome volume and relative amounts of DNA per chromosome from plants growing on this site and those on a control site. These nuclear parameters indicate the relative radio-sensitivity of a species and would demonstrate the total effectiveness of the low-level chronic radiation in altering plant succession. The radiosensitive plant Tradescantia clone 02 was also grown in five soil samples from the mill tailings which represented a progressive increase in radioactivity. The purpose was to determine how effective these radiation levels are in altering reproductive integrity, fecundity, and somatic mutation rates in radiosensitive plant species.
There was a difference in species composition between plant communities growing on the mill tailings as compared to the controls as determined by coefficient of community. However, there was no difference in interphase chromosome volume or relative amounts of DNA per chromosome between plants growing on these two sites. The difference in species composition is attributed to the length of time each site has been undergoing succession, with the control site in a more advanced stage. Tradescantia grown in soil with a radiation dose greater than 0.10 mR/hr had significantly reduced reproductive integrity and fecundity, as measured by the number of stunted hairs on a stamen and poll en viability, and increased numbers of somatic mutations. Based on these data the radioactive mill tailings from the Vitro Chemical Plant have the potential to alter plant successional patterns due to their detrimental effect on any species that is relatively radiosensitive.
Smart Farming for Food Security

description: The impacts on global food supply chains due to Russia’s invasion of Ukraine have exacerbated an already unstable European agri-food sector that has suffered a series of industry losses and disruptions due to climate disasters and the COVID-19 pandemic.

In 2022, production costs for the European agri-food sector have soared, with high energy costs threatening the continuity of food, feed, and agri-food commodities causing companies to halt production, lay off staff or go out of business altogether. Due to gas shortages, European fertilizer plants have shut down while sanctions between the EU and Russia have led to fertilizer prices tripling from a year ago. In the context of these turbulent times, farmers are being forced to make difficult decisions with the long-term impacts on food security yet to be known. With inflation affecting the entire production chain, one certainty is that consumers will pay the price.

description: Can modern cosmological observations be reconciled with a general-relativistic Universe without an anti-gravitating energy source? Usually, the answer to this question by cosmologists is in the negative, and it is commonly believed that the observed excess dimming of supernovae relative to that in the Milne model is evidence for dark energy. In this paper, we develop theorems that clarify the conditions for such an excess dimming, based on which we argue that the answer to the above question may counter-intuitively be `yes'.

title: Potential For Cattle Grazing on Sheep Range in Southwest Utah
Creators: name: Gutierrez-Garza, Jose Salvador
Publisher: name: Utah State University
Year: 1978

description: A study was conducted on pastures grazed by sheep in late winter at the Desert Experimental Range in southwest Utah. Estimates of plant cover and herbage production were obtained in 1977 and used to examine longterm trends in the vegetation.
The nutritional value of the six most important species of the area was assessed by chemical analysis. In addition, a management strategy was developed for obtaining some utilization of the range during the spring and summer months without affecting the traditional winter use by sheep.
Long-term records (since 1937) in cover suggest a modest increase in grasses and a decrease in shrub cover. But there are insufficient data to infer range condition and trend. Long-term herbage production data (since 1938) show a substantial increase in annual species over the last twenty years. The year-to-year variability is very high, apparently depending on the prevailing climate conditions. Grass production was less variable than shrub production.
No significant difference (P
Based on the nutritional analysis of forage and long-term records of climate and plant production, a management strategy was devised to make more efficient use of the salt-desert shrub vegetation. Climatic conditions will favor good forage production about four years out of ten. Perennial grasses, annuals, and winterfat (Ceratoides lanata) showed better response to favorable climatic conditions than the other species. It is proposed in this study that, in these years of high production, the range could be used by cattle in the spring or summer, and thereby al low occasional resting of mountain summer pastures. Such opportunistic summer grazing on the desert should not be detrimental to winter sheep grazing, but the plan would need to be field-tested on an experimental or trial basis to evaluate ecological responses to increased livestock use.

description: "From this paper three main themes emerge: the importance of peri-urban areas, the emergence of conflict as a result of weak government and stressed traditional systems and finally, the need for new and more inclusive systems of governance. Increasingly both material (infrastructure, housing, services, etc.) and nonmaterial (state-society relations, governance, etc.) needs are seen as complimentary to sustainable urban development. This working paper will primarily focus on what can be achieved in terms of creating more inclusive and effective forms of governance, building on international and Pacific perspectives and experiences." - page 1

description: We present Recurrent Vision Transformers (RVTs), a novel backbone for object detection with event cameras. Event cameras provide visual information with sub-millisecond latency at a high-dynamic range and with strong robustness against motion blur. These unique properties offer great potential for low-latency object detection and tracking in time-critical scenarios. Prior work in event-based vision has achieved outstanding detection performance but at the cost of substantial inference time, typically beyond 40 milliseconds. By revisiting the high-level design of recurrent vision backbones, we reduce inference time by a factor of 6 while retaining similar performance. To achieve this, we explore a multi-stage design that utilizes three key concepts in each stage: First, a convolutional prior that can be regarded as a conditional positional embedding. Second, local and dilated global self-attention for spatial feature interaction. Third, recurrent temporal feature aggregation to minimize latency while retaining temporal information. RVTs can be trained from scratch to reach state-of-the-art performance on event-based object detection - achieving an mAP of 47.2% on the Gen1 automotive dataset. At the same time, RVTs offer fast inference (<12 ms on a T4 GPU) and favorable parameter efficiency (5 times fewer than prior art). Our study brings new insights into effective design choices that can be fruitful for research beyond event-based vision.

Optimal control of martingales in a radially symmetric environment

description: We study a stochastic control problem for continuous multidimensional martingales with fixed quadratic variation. In a radially symmetric environment, we are able to find an explicit solution to the control problem and find an optimal strategy. We show that it is optimal to switch between two strategies, depending only on the radius of the controlled process. The optimal strategies correspond to purely radial and purely tangential motion. It is notable that the value function exhibits smooth fit even when switching to tangential motion, where the radius of the optimal process is deterministic. Under sufficient regularity on the cost function, we prove optimality via viscosity solutions of a Hamilton-Jacobi-Bellman equation. We extend the results to cost functions that may become infinite at the origin. Extra care is required to solve the control problem in this case, since it is not clear how to define the optimal strategy with deterministic radius at the origin. Our results generalise some problems recently considered in Stochastic Portfolio Theory and Martingale Optimal Transport.

description: This working paper investigates the livelihoods, trajectories, networks and self-generated opportunities of vulnerable migrants in refugee-like situations in Dar es Salaam. Its main purpose is to arrive at a deeper understanding of protracted displacement through a ‘figurational approach’, which stresses the networks and the interdependencies of urban refugees in Dar es Salaam, across Tanzania, and across national borders. Refugees’ social relations do not unfold in a vacuum but are shaped by the regimes of aid and asylum that govern their lives. In a context of constant fear of imprisonment and deportation, this working paper gives particular attention to the alliances that the vulnerable migrants build within Dar es Salaam. It underlines their agency and coping strategies, as they bring with them many valuable skills. Capitalising on these skills can result in longstanding partnerships between vulnerable migrants and locals. Spaces of freedom where displaced people do not need to live in a perpetual state of fear and uncertainty are equally important. More than focusing on constraints, this paper underlines the urban refugees’ agency and survival strategies. We pay particular attention to the mobility and connectivity of female urban refugees, also within a digital context. Through (social media) entrepreneurship, women in refugee- like situations have managed to overcome immobilisation and create new opportunities for themselves. By analysing a variety of life situations throughout this paper, we seek to recognise and promote urban refugees’ agency and dignity.

description: Background and Purpose— Endovascular treatment is the standard of care for the treatment of proximal largearterial occlusion related ischemic strokes. Patients with acute ischemic stroke in the anterior circulation are at riskfor either primary or, following mechanical thrombectomy, secondary occlusion of the distal arteries. The safety andefficacy of endovascular treatment in the treatment of distal intracranial occlusions has not been well studied.Methods— From an institutional database we selected consecutive patients treated with stent retriever for distalarterial occlusions. Recanalization success was measured by applying the Thrombolysis in Cerebral Infarction (TICI)score. To assess safety, we recorded device-related procedural events and potentially device-related hemorrhageson follow-up imaging. Infarcts in the dependent territory served as a measure for efficacy. Distal arterial occlusionswere defined as any segment beyond anterior communicating [ACOM] in anterior cerebral artery (ACA), beyondposterior communicating [PCOM] in posterior cerebral artery, or occlusion at or distal to the middle cerebral artery(MCA)-M2 segment.Results— Of 330 patients included in this analysis, we identified 42 (12%) patients with distal arterial occlusions.The recanalization rate with use of a stent retriever was 81% in these 42 patients. Periprocedural complicationsincluded vasospasms (n = 3, 7.1%) and distal embolization (n = 2, 4.8%). Asymptomatic post-thrombectomyintracerebral hemorrhages were seen in 9.52% (4/42) of the patients. At 90 days, functional independence (definedby modified Rankin scale of 0-2) was achieved in 88.7% (36/42) of patients with distal arterial occlusions.Conclusions— Endovascular treatment using stent retrievers results in high rates of recanalization and functionalindependence in ischemic stroke patients with distal arterial occlusions.

description: We present, for the first time, the complete off-shell $4D, {\cal N}=2$ superfield actions for any free massless integer spin ${\bf s} \geq 2$ fields, using the ${\cal N}=2$ harmonic superspace approach. The relevant gauge supermultiplet is accommodated by two real analytic bosonic superfields $h^{++}_{α(s-1)\dotα(s-1)}$, $h^{++}_{α(s-2)\dotα(s-2)}$ and two conjugated complex analytic spinor superfields $h^{+3}_{α(s-1)\dotα(s-2)}$, $h^{+3}_{α(s-2)\dotα(s-1)}\,$, where $α(s) := (α_1\ldots α_s), \dotα(s) := (\dotα_1\ldots \dotα_s)$. Like in the harmonic superspace formulations of ${\cal N}=2$ Maxwell and supergravity theories, an infinite number of original off-shell degrees of freedom is reduced to the finite set (in WZ-type gauge) due to an infinite number of the component gauge parameters in the analytic superfield parameters. On shell, the standard spin content $({\bf s, s-1/2, s-1/2, s-1})$ is restored. For ${\bf s}=2$ the action describes the linearized version of "minimal" ${\cal N}=2$ Einstein supergravity.
