Estimating Kappa within a Low-Seismicity Region in Northern New Mexico Using Data Recorded by the Los Alamos Seismic Network

Published: April 2024

ABSTRACT
We quantify the total attenuation, κ, and the attenuation component due to near-surface site effects, κ0, in a region in northern New Mexico using data recorded by the Los Alamos Seismic Network. The area is characterized by low seismicity, where most of the well-recorded earthquakes have magnitudes between 1 and 2. This magnitude range poses a challenge for commonly used kappa methods because the high-frequency attenuation cannot be confidently isolated from the bandwidth in which the corner frequency roll-off occurs. We determine through synthetic experiments that estimates of κ within this range have quantifiable biases that depend on source (corner frequency), site (κ magnitude), and data quality characteristics (fitting bandwidth), which can be used to correct estimated κ from three commonly used kappa methods. Using 412 recorded earthquakes, we show that a bias correction results in κ distributions and κ0 estimates that are more consistent between the three methods, suggesting that the bias correction results in κ values with higher fidelity. Using the bias-corrected κ, we find κ0 between 0.038 and 0.049 s within the Valles Caldera and between 0.026 and 0.066 s on Los Alamos National Laboratory property, values near those commonly used in the western United States. We find that a main limitation in the quality of κ0 is the small number of usable waveforms at some stations, which will to improve as more earthquakes are recorded. This contrasts with other aspects, such as fitting bandwidth and source and path variability, which are unlikely to change in the future and will ultimately be the limiting factor in κ0 resolution. Overall, our results suggest that the bias-correction scheme presented here could potentially be used in other regions where small-magnitude earthquakes are prevalent. However, future work should look to verify that bias-corrected κ estimates show consistency with those retrieved from higher magnitude earthquakes.

Published: April 2024

A pesquisa no Brasil percorreu um longo caminho até a sua inserção junto ao ensino e à extensão, sendo que um dos objetivos desse trinômio é a capacitação de profissionais atentos às necessidades sociais contemporâneas. Hoje, um dos temas profícuos para a academia brasileira é a construção da Rota Bioceânica. Com o objetivo de mapear o que tem sido produzido cientificamente, foi realizada uma revisão integrativa da literatura, utilizando as bases virtuais SciELO e Portal de Periódicos da Capes. Como complementação, analisou-se o Diretório de grupos de pesquisa registrados no CNPq. As buscas resultaram em 66 artigos e 02 grupos de pesquisa. O primeiro artigo encontrado sobre a temática foi publicado em 2000 e, quase duas décadas depois, em 2018 ocorreu uma propulsão nas produções brasileiras. A Revista com mais publicações foi a Interações, os grupos que mais publicaram fazem parte da Rede Universitária da Rota de Integração Latino-Americana (UniRila), com predominância dos brasileiros. Concluiu-se que há uma concentração das publicações no Mato Grosso do Sul, Estado aonde a Rota vem sendo construída e, internacionalmente, os estudos se limitam aos países envolvidos. Os temas mais abordados são referentes ao turismo, desenvolvimento territorial e infraestrutura. As lacunas apontam para a falta de envolvimento de docentes e discentes de outros Estados brasileiros, a homogeneidade nos componentes dos grupos registrados no Diretório, apesar da UniRila estar ativa e demonstrar parcerias em torno da elaboração das investigações. Há também hiatos relativos a outros temas essenciais e ausência de abordagens inerentes à extensão, sendo evidenciados o ensino e a pesquisa. A revisão demonstrou que a Rede ainda é nova e tem muito a ser trabalhado, inclusive a ciência é uma das aliadas na perspectiva do posicionamento do Mercosul no Pacífico, nas cooperações internacionais e no desenvolvimento territorial.

Considerando la implementación del Corredor Bioceánico, este artículo analiza el impacto que esto tendrá en las relaciones laborales que se verán fortalecidas en su ámbito, con el objetivo de analizar los sistemas jurídico-laborales de los países involucrados, así como las normativas internacionales y regionales aplicables, con el fin de demostrar la necesidad de proteger y promover los derechos humanos sociales. Como resultado, se verifica la ocurrencia de una serie de asimetrías entre los países parte del proyecto, con diferencias de nivel de protección de los derechos humanos sociales que al final importan no tan solo en divergencias normativas, pero en deficiencias de protección de las relaciones de trabajo en todo proyecto, reafirmando la necesidad de protección y promoción de los derechos sociales. Además, se tiene como un camino posible para la mitigación de los dichos puntos el fortalecimiento de las instituciones estatales y laborales, en particular los sindicatos. Para eso, se utiliza la investigación bibliográfica y el método deductivo como soporte de análisis.
Scour-depth variability controls channel-scale stratigraphy in experimental braided rivers
Authors: Zhao Feifei , Ganti Vamsi , Limaye Ajay B. 
Published: April 2024

ABSTRACT
Braided rivers distribute sediment across landscapes, often forming wide channel belts that are preserved in stratigraphy as coarse-grained deposits. Theoretical work has established quantitative links between the depth distribution of formative channels in a braided river and the geometry of their preserved strata. However, testing these predictive relationships between geomorphic process and stratigraphic product requires examining how braided rivers and their deposits coevolve, with high resolution in both space and time. Here, using a series of four runs of a physical experiment, we examine the controls of water discharge and slope on the resulting geometry of preserved deposits. Specifically, we focus on how a twofold variation in water discharge and initial riverbed slope affects the spatiotemporal distribution of channel depths and the geometry of preserved deposits of a braided river. We find that the channel depths in the laboratory experiment are described by a two-parameter gamma distribution and the deepest scours correspond to zones of erosion at channel-belt margins and channel-thread confluences in the channel belt. We use a reduced-complexity flow model to reconstruct flow depths, which were shallower compared to channel thalweg depths. Synthetic stratigraphy built from timeseries of topographic surfaces shows that the distribution of cut-and-fill-unit thickness is invariant across the experiments and is determined by the variability in scour depths. We show that the distribution of cut-and-fill-unit thickness can be used to reconstruct formative-channel-depth distributions and that the mean thickness of these units is 0.31 to 0.62 times the mean formative flow depth across all experiments. Our results suggest that variations in discharge and slope do not translate to measurable differences in preserved cut-and-fill-unit thickness, suggesting that changes in external forcings are likely to be preserved in braided river deposits only when they exceed a certain threshold of change.
An Integrated Method for External and Internal Scheduling of Parallel Cluster Tools
Authors: YANG FAJUN , Mönch Lars 
Published: April 2024

Abstract
Cluster tools are integrated machines for wafer processing in semiconductor wafer fabrication facilities (wafer fabs). Since different kinds of wafers can circulate in a cluster tool simultane-ously, it is a fully automated machine environment. The development of scheduling ap-proaches for these extremely expensive machines is essential for improving their operations. We study a scheduling problem on the work center level, i.e. for parallel cluster tools. The performance measure is the total weighted tardiness. All jobs are available at scheduling time. Two different biased random-key genetic algorithms (BRKGAs) are designed to assign jobs to cluster tools and to compute sequences for each single cluster tool. We establish algorithms to compute the time a job spent in a cluster tool, called processing time, given the sequence in which the jobs are processed there. They are embedded into the BRKGAs. Computational ex-periments based on randomly generated problem instances are carried out. The results demon-strate that the proposed metaheuristics perform well with respect to solution quality and com-puting time.

Abstract

Background/Objectives: To compare the effects of vitrectomy alone and vitrectomy combined with subretinal injection of recombinant tissue plasminogen activator (rt-PA) for submacular haemorrhage(SMH).Subjects/Methods: In this retrospective study, 52 patients were diagnosed with SMH, of whom 43 were identified as having polypoidal choroidal vasculopathy (PCV). 19 patients underwent vitrectomy with intravitreal rt-PA injection into the submacular space, and 33 underwent only vitrectomy. Best visual acuity was recorded preoperatively, as well as at 1 week, 1 month, and 3 months postoperatively. Using the Heidelberg optical coherence tomography (OCT) follow-up model, the areas and heights of pigment epithelial detachment (PED), areas of retinal fluid (RF), and central macular thickness (CMT) were measured. Retinal fibrosis within the vascular arcade was evaluated using Optos during follow-up.Results One week postoperatively, the combined group started showing a significant decrease in the PED area, height, CMT and RF, with notable improvements in visual acuity at 1 month, whereas in the vitrectomy-only group, PED area significantly decreased after 1 week, along with a significant reduction in the visual acuity in the first month, but a subsequent increase in the third month. CMT only showed significantly reduction at 1week. In the combined group, two patients developed scars within the vascular arcade in the posterior pole during follow-up, whereas in the vitrectomy-only group, this occurred in 13 patients.Conclusion Vitrectomy with rt-PA injection into the submacular space demonstrates effectiveness and safety for treating SMH, as well as good prevention of scarring.

Abstract

The antigen-mediated B cell isolation method, based on the detection of surface IgG (sIgG), has increased the efficiency of therapeutic antibody (Ab) discovery. However, the reduction in sIgG expression on B cells during plasma cell differentiation presents challenges as it enables Ab production from only a small subset of B cells (e.g., memory B cells). The present study aimed to addressed this problem by developing a workflow to isolate human-IgG-secreting hybridoma cells produced by cell fusion, the majority of which express sIgG. We showed that our sIgG-based antigen-coated bead separation method efficiently enriched hybridoma cells expressing antigen-specific Abs with a yield of 83.5% (from the cell fusion pool) and a positive rate of 73.2%. Furthermore, because the separation could be performed after only a short (1−2-day) culture period following cell fusion, diverse hybridoma clones could be obtained, minimizing clonal selection and the incidence of duplicates. Given that the expression of membrane-bound IgG and sIgG are regulated by different splicing mechanisms, we speculate that the cell fusion step potentially attenuated the suppression of human sIgG expression. Overall, our proposed method is expected to markedly improve the efficiency of therapeutic Ab candidate production, which will have important clinical implications.

Abstract
Background Limited resources in health and social care and long waiting lists for autism assessment are resulting in high numbers of autistic people not being adequately supported. We sought to explore the feasibility and effectiveness of meeting this support need through an end-to-end digital self-referral and digital mental health service.Methods Together with Health and Social care teams and young autistic people we developed a self-referral pathway that allowed young autistic people (aged 16–25) to access the digital self-management support system, Brain in Hand (BiH), without the need for diagnosis or referral by an external agency. Participants were reached using digital media channels which linked to a BiH landing page. Reach, progress and engagement through the pathway was monitored and participants were surveyed on their eligibility and suitability for BiH.Results A total of 243 BiH licences were issued within 9 weeks of the start of the digital media campaign which reached nearly half a million people with close to 20,000 clicking through to the BiH landing page. Most of the young people being issued with the digital support tool demonstrated high levels of need, 69% experienced clinically significant depression, 83% anxiety, 99% moderate or high executive function challenges, and 60% lacked current support.Conclusions This pilot demonstrates that young people understand their needs and directing them to a support service through a digital media campaign presents an efficient and effective approach in reaching young autistic people in need. This suggests that digital media channels and self-referral could offer a practical solution to broaden access to a range of digital mental health platforms without placing additional resource burden on health and care teams.
Deformation characteristics and failure mechanisms induced by rainfall of the Zhoujia landslide in southwestern China

Published: April 2024

Abstract

The Zhoujia landslide, which has a potential risk of instability due to the complex engineering geological conditions, is located near the dam site of the Kala Hydropower Station and poses a significant threat to the safety of the power station. In this paper, a comprehensive assessment of the deformation characteristics and failure mechanisms of the Zhoujia landslide is conducted through field investigations, in situ monitoring data, and numerical simulations. The results indicate that the Zhoujia landslide is a giant ancient accumulation-landslide currently in the creep stage. Deformations of the landslide are characterized by frontal traction and rearward tearing. Deformations are concentrated mainly in Zone B1, with no signs of convergence yet, while Zones A and B2 show smaller and converging deformations. It is found that, through correlation analysis, rainfall is the primary triggering factor for landslide deformations, with a time delay of 1–2 months. Preliminary results from numerical simulations of plastic zones of the landslide indicate a layered failure pattern for the Zhoujia landslide. Three potential failure patterns are identified: sliding along the shallow gravel silt layer in Zone B1, sliding along the deep gravel silt layer in Zone B1, and overall sliding along the bottom sliding zone in Zone B1. The results in this paper will provide guidelines for early warning and engineering control of the Zhoujia landslide during the construction and after the completion of the Kala Hydropower Station project.
Particle Swarm Optimization with Latin Hypercube Sampling for Mobility-Aware Task Offloading in D2D-Assisted MEC Networks

Published: April 2024

Abstract

In this paper, we consider a Device-to-Device (D2D)-assisted Mobile Edge Computing (MEC) system in which the edge server collaboratively performs tasks with users who possess mobile characteristics. The computational resources of the edge server and the users are limited. Our objective is to minimize latency and energy consumption while maximizing system stability by determining the offloading decisions for all tasks. However, solving this problem is particularly challenging due to the coupling between offloading decisions and user mobility characteristics. To address this challenge, a Particle Swarm Optimization (PSO) algorithm based on Latin Hypercube Sampling (LHS) is proposed. PSO can be employed for iterative computation to obtain the optimal solution by treating the offloading decisions for all tasks as particles. Furthermore, employing LHS for the initialization and updating of the particle swarm can significantly enhance the performance and convergence of the PSO. Simulation results indicate that our proposed algorithm outperforms other algorithms significantly in terms of latency, energy consumption, and system stability while also exhibiting excellent robustness.

Abstract

MRI study of the human fetal brain is a complicated, important and difficult scientific problem, which has an application inclinical practice. Meanwhile, the boundaries of individual geometric characteristics of fetal brain structures are still blurred andrequire a clarification. A sample of 105 participants with healthy fetal brain, is considered. It is shown that the relationshipbetween the growth of individual brain structures sizes (cerebral fronto-occipital diameter, cerebral biparietal diameter, corpuscallosum length, transverse cerebellum diameter, vermis height) differs depending on the trimester. The advantage of lineardependence for the growth of brain structures for each of the considered trimesters was demonstrated versus power-lawregression. The resulting growth models for each trimester will make it possible to more accurately determine whether a casecorresponds to the norm using a combination of several linear dimensions at once.
