Published: August 2022

ABSTRACT. We present a seismic migration algorithm that calculates travel times and amplitudes based on the paraxial extrapolation of the dynamic ray tracing. We use a target-oriented approach with automatic selection of migration parameters and seismic traces that will compose the image. By associating the ray parameter (slowness vector) with the amplitudes of the seismic data, we reach a new form of migration amplitude conditioner that acts as a filter and may increase the resolution of reflectors and faults. On the other hand, when using the seismic amplitudes as weights, we can estimate the slowness vectors associated with the true seismic reflectors in depth. We apply this method to the synthetic seismic data of the Marmousi velocity model. When comparing the migrated seismic section to the true interval velocity model, we can see a precise matching of the geological features in a high-resolution pattern.Keywords: seismic migration, target-orientation, dynamic ray tracing, paraxial amplitude extrapolation. Migração por Traçado de Raios de Alta ResoluçãoRESUMO. Apresentamos um algoritmo de migração sísmica que calcula tempos e amplitudes de viagem com base na extrapolação paraxial do traçado dinâmico de raios. Utilizamos uma abordagem orientada a alvos com seleção automática dos parâmetros de migração e dos traços sísmicos que irão compor a imagem. Ao associar o parâmetro de raio (vetor de vagarosidade) às amplitudes dos dados sísmicos, chegamos a uma nova forma de condicionador de amplitudes de migração que atua como filtro e pode aumentar a resolução de refletores e falhas. Por outro lado, ao usar as amplitudes sísmicas como pesos, podemos estimar os vetores de vagarosidade associados aos verdadeiros refletores sísmicos em profundidade. Aplicamos este método aos dados sísmicos sintéticos do modelo de velocidade de Marmousi. Ao comparar a seção sísmica migrada com o modelo de velocidades intervalar verdadeiro, podemos ver uma correspondência precisa das feições geológicas em um padrão de alta resolução.Palavras-chave: migração sísmica, orientação ao alvo, traçado dinâmico de raios, extrapolação paraxial de amplitude.

ABSTRACT. With the installation and growth of the Brazilian Seismographic Network (RSBR) since 2011, it is now possible to detect and locate events with magnitudes lower than 3.5 mb for Brazil, and better study the local and regional seismicity. Nevertheless, most of these events are located using 1D velocity models that lead to larger uncertainties precluding any correlation with the known geological structures. The use of heterogeneous 3D velocity models better predicts the travel times and guarantees the accuracy of hypocenter location; however, there is not yet a calibrated 3D velocity model for the South American Platform (SAP). In this study, integrating multiple local and regional geological and geophysical knowledge and average velocities of the crust and mantle, we have elaborated 3D P- and S-wave velocity models for the SAP, including the Central Andes area (down to 900 km). We tested the model locating the well-known 1998 Andean Aiquile earthquake (Bolivia), 6.6 Mw, obtaining successful results when compared with its ground truth location. We also satisfactorily located two other recent important events of the SAP, using local and regional body wave arrivals recorded by the RSBR. Finally, S-wave arrivals of near stations helped to constrain the event depths to expected values.Keywords: heterogeneous velocity model, Brazilian seismicity; hypocenter location; NonLinLoc. P- and S-wave 3D velocity models for the South American platformRESUMO. Em decorrência da implantação da Rede Sismográfica Brasileira (RSBR) em 2011, tornou-se possível detectar e localizar eventos com magnitudes menores de 3,5 mb no Brasil e aprofundar o estudo da sismicidade local e regional. Porém, a maioria desses eventos são localizados utilizando-se modelos de velocidade 1D, resultando em incertezas que não permitem correlacionar os hipocentros com as estruturas geológicas conhecidas. Em contrapartida, o uso de modelos 3D de velocidade prediz melhor os tempos de percurso das ondas e garante precisão na localização de hipocentros; porém, ainda não haviam sido desenvolvidos modelos 3D calibrados para a plataforma Sul-Americana. No presente estudo, integrando-se informações geológica e geofísica, local e regional, e velocidades médias da crosta e manto foram elaborados modelos 3D de velocidade das ondas P e S para a Plataforma Sul-americana e para os Andes Centrais (até 900 km de profundidade). Para testar a confiabilidade dos modelos, foi localizado o evento andino de Aiquile 1998, 6,6 Mw (Bolívia) usando-se chegadas regionais da onda P, com resultados compatíveis com o melhor epicentro conhecido. Também foram localizados satisfatoriamente dois outros eventos importantes. Finalmente, o uso de leituras da onda S de estações próximas restringe a profundidade hipocentral para valores esperados em cada caso.Palavras-chave: modelo de velocidade heterogêneo; sismicidade brasileira; localização de hipocentros, NonLinLoc.

ABSTRACT. The Beirut, Lebanon, explosion on August 4, 2020, one of the largest non-nuclear explosion in world history, was detected by infrasound and seismic stations of the International Monitoring System (IMS), a network designed to detect and locate nuclear explosions in violation to the Comprehensive Nuclear-Test-Ban Treaty (CTBT). The explosion was registered by five infrasound and three seismic stations, located up to 6,000 km and 2,400 km distant, respectively. These IMS data, complemented by data from seven ocean bottom stations, were used to estimate epicenter, magnitudes (mb = 3.6 and Mw = 3.3) and explosive yield. The explosion location was determined by infrasound (33,864ºN and 34,311ºE) and seismic (33,859ºN and 35,567ºE) technologies. The yield was calculated using two approaches: the seismic P-wave magnitude and the maximum amplitude of the infrasonic signal, resulting in 0.40 kt and 1.48 kt of trinitrotoluene (TNT) equivalent, respectively. The aim of this work is testing the performance of the IMS network in detection, location and characterizing of an explosion, developing skills and capacity of researchers to accurately locate events of interest to the CTBT. Additionally, we intend to highlight the importance of CTBT and arouse interest in the use of IMS data.Keywords: Beirut explosion; seismic event detection; infrasound event detection; CTBTO; nuclear explosion. RESUMO. A explosão de Beirute, Líbano, em 4 de agosto de 2020, uma das maiores explosões não nucleares da história mundial, foi detectada por estações de infrassom e sísmica do Sistema de Monitoramento Internacional (IMS), uma rede designada para detectar e localizar explosões nucleares em violação ao Tratado de Proibição Total de Testes Nucleares (CTBT). A explosão foi registrada por cinco estações de infrassom e três estações sísmicas, localizadas a até 6.000 km e 2.400 km de distância, respectivamente. Esses dados IMS, complementados por dados de sete estações de fundo oceânico, foram usados para estimar o epicentro, magnitudes (mb = 3,6 e Mw = 3,3) e rendimento explosivo. O local da explosão foi determinado pelas tecnologias infrassônica (33.864ºN e 34.311ºE) e sísmica (33.859ºN e 35.567ºE). O rendimento foi calculado usando duas abordagens: a magnitude da onda P e a amplitude máxima do sinal infrassônico, resultando em 0,40 kt e 1,48 kt equivalente de trinitrotolueno (TNT), respectivamente. O objetivo deste trabalho é testar o desempenho da rede IMS na detecção, localização e caracterização de uma explosão, desenvolver habilidades e capacidade dos pesquisadores para localizar com precisão eventos de interesse do CTBT. Adicionalmente, pretendemos divulgar a importância do CTBT e despertar o interesse na utilização dos dados do IMS.Palavras-chave: Explosão em Beirute; detecção de evento sísmico; detecção de evento infrassônico; CTBTO, explosão nuclear.
The Effect of Financial Statement Incomparability on Investment Decisions
Authors: Anderson Spencer B. 
Published: August 2022

ABSTRACTI use standard setters’ description of comparability to conceptualize two forms of incomparability in financial reporting. Using a laboratory experiment, I construct states of both comparability and incomparability and investigate investors’ capital allocation decisions under each. Benchmarking against states of comparable reporting, I find that incomparable reporting making different economics look alike results in lower-quality investment decisions, relative to incomparable reporting making similar economics look different. My evidence suggests the difference in investment quality is due to the reduced ability of supplemental disclosures to compensate for one type of incomparability relative to the other type. The study uses a setting holding other reporting characteristics, such as faithful representation, constant, and results are robust to alternative configurations of incomparability. Collectively, my results suggest that the type of incomparability has differential effects on the quality of investment decisions. My findings should inform standard setters aiming to help users allocate capital.JEL Classifications: G11; M41.

<p> </p>
<p><strong>Background:</strong> The efficacy and safety of continuous glucose monitoring (CGM) in adjusting inpatient insulin therapy has not been evaluated. </p>
<p><strong>Methods:</strong> This randomized trial included 185 general medicine and surgery patients with type 1 and type 2 diabetes treated with a basal bolus insulin regimen. All subjects underwent point-of-care (POC) capillary glucose testing before meals and bedtime. Patients in the standard of care (POC group) wore a blinded Dexcom G6 CGM with insulin dose adjusted based on POC results; while in the CGM group, insulin adjustment was based on daily CGM profile. Primary endpoints were differences in time in range (TIR, 70-180 mg/dL) and hypoglycemia (<70 mg/dL and <54 mg/dL). </p>
<p><strong>Results: </strong>There were no significant differences in TIR (54.51%±27.72 vs 48.64%±24.25, p=0.14), mean daily glucose (183.2±40 mg/dL vs 186.8±39 mg/dL, p=0.36), percent of patients with CGM values <70 mg/dL (36% vs 39%, p=0.68) or <54mg/dL (14% vs 24%, p=0.12) between CGM-guided and POC group. Among patients with ³ 1 hypoglycemic event, compared to POC, the CGM group experienced a significant reduction in hypoglycemia reoccurrence (1.80±1.54 vs 2.94±2.76 events/patient, p=0.03), lower percentage of time below range (TBR) <70 mg/dL (1.89%±3.27 vs 5.47%±8.49, p=0.02), and lower incidence-rate ratio <70 mg/dL (0.53, 95% CI:0.31-0.92) and <54 mg/dL (0.37, 95% CI:0.17-0.83).</p>
<p><strong>Conclusion:</strong> The inpatient use of real-time Dexcom G6 CGM is safe and effective in guiding insulin therapy resulting in a similar improvement in glycemic control and a significant reduction of recurrent hypoglycemic events compared to POC-guided insulin adjustment.</p>

<p> </p>
<p><strong>Objective</strong></p>
<p>To investigate trends, optimal levels for cardiometabolic risk factors, and multifactorial risk control in diabetic nephropathy and end-stage kidney disease (ESKD) in patients with diabetes and matched controls. </p>
<p><strong>Research Design and Methods</strong></p>
<p>This study included 701,622 patients with diabetes from the Swedish National Diabetes Register and 2,738,137 controls. Trends were analyzed with standardized inc­idence rates. Cox regression was used to assess excess risk, optimal risk factor levels, and risk according to the number of risk factors, in diabetes. </p>
<p><strong>Results</strong></p>
<p>ESKD incidence among patients with and without diabetes initially declined until 2007 and increased thereafter, whereas diabetic nephropathy decreased throughout follow-up. In patients with diabetes, baseline values for glycated hemoglobin, systolic blood pressure, triglycerides, and body mass index were associated with outcomes. Hazard ratio for ESKD in patients with type 2 diabetes who had all included risk factors at target was 1.60 (95% CI, 1.49–1.71) compared with controls, and in type 1 diabetes 6.10 (95% CI, 4.69–7.93). Risk for outcomes increased in a stepwise fashion for each risk factor not at target. Excess risk for ESKD in type 2 diabetes showed a hazard ratio of 2.32 (95% CI, 2.30–2.35) and in type 1 diabetes, 10.92 (95% CI, 10.15–11.75), compared with controls.</p>
<p><strong>Conclusions</strong></p>
<p>Incidence of diabetic nephropathy has declined substantially, whereas ESKD incidence has increased. Traditional and modifiable risk factors below target levels were associated with lower risks for outcomes, particularly notable for the causal risk factors of SBP and HbA1c, with potential implications for care. </p>

Published: August 2022

<p>A quarter of the world’s population is estimated to meet the criteria for metabolic syndrome, a cluster of cardiometabolic risk factors that promote development of coronary artery disease and type II diabetes, leading to increased risk of premature death and significant health costs. In this study we investigate whether the genetics associated with metabolic syndrome components mirror their phenotypic clustering. A multivariate approach that leverages genetic correlations between fasting glucose, high-density lipoprotein cholesterol, systolic blood pressure, triglycerides, and waist circumference was used; which revealed that these genetic correlations are best captured by a genetic one factor model. The common genetic factor genome-wide association study (GWAS) detects 235 associated loci, 174 more than the largest GWAS on metabolic syndrome to date. Of these loci, 53 (22.5%) overlap with loci identified for two or more metabolic syndrome components, indicating that metabolic syndrome is a complex, heterogeneous disorder. Associated loci harbour genes that show increased expression in the brain, especially in GABAergic and dopaminergic neurons. A polygenic risk score drafted from the metabolic syndrome factor GWAS predicts 5.9% of the variance in metabolic syndrome. These results provide mechanistic insights in the genetics of metabolic syndrome and suggestions for drug targets, especially fenofibrate, which has the promise of tackling multiple metabolic syndrome components. </p>

Portanto, o objetivo principal do trabalho é analisar os artifícios jurídicos utilizados pelos respectivos governos de Brasil e de Cuba para adoção dessas medidas distintas, e se essas são legais ou não perante suas respectivas jurisprudências. Somado a isso, busca-se analisar a relação dos presidentes de cada nação com as demais esferas de poder, responsáveis em pôr em prática as medidas profiláticas.
KEBIJAKAN OTONOMI PERGURUAN TINGGI INDONESIA: ANTARA PRIVATISASI DAN KOMERSIALISASI

The basic principle of the New Public Management (NPM) paradigm is to run state administration as it moves the business sector (run government like a business or market as a solution to the ills in the public sector). This strategy needs to be implemented so that the old model of bureaucracy that is slow, rigid and bureaucratic is ready to answer the challenges of the globalization era. The privatization of higher education in the form of PTN BH and BLU is an autonomous form of higher education institutions by adopting the values of NPM. In practice, there appears to be a shift and misunderstanding of the value of privatization which is interpreted as the commercialization of higher education. This article concludes that this higher education privatization policy has a negative impact, namely the commercialization of higher education, which if allowed to continue will grow the capitalization of education. Education can only be accessed by the owners of capital, while the lower class people are increasingly marginalized. Evaluation of the higher education privatization policy must be carried out immediately by the government in order to make improvements even if it is necessary to revoke and change the privatization policy of higher education.Keywords: Education, Privatization, Commercialization

Abstract
A serious environmental problem can arise from the presence of pesticides in soils and waters. Hence, in this study we have carried out the adsorption of the Thiabendazole fungicide onto four soils collected from several areas in Morocco as Larache, Laouamra, Ksar kebir and Tlata drissana. Physicochemical properties, elemental analysis, X-ray diffraction (XRD) were investigated to characterise the four selected soils. The experimental equilibrium data were analysed using Langmuir, Freundlich models. The equilibrium data were best described by a Langmuir model for all adsorbents. The maximum estimated adsorption capacity was 0.747 mg∙g−1, 0.751 mg∙g−1, 0.473 mg∙g−1 and 1.083 mg∙g−1, for Larache, Laouamra, Ksar kebir and Tlata drissana soils, respectively.
The depositional environment of the Koeris Formation in the Aggeneys-Gamsberg ore district, South Africa

Abstract
The Koeris Formation in the Mesoproterozoic Aggeneys-Gamsberg ore district (South Africa) is located in the hanging wall of an unconformity, only metres above the giant Gamsberg and Big Syncline Pb-Zn ore deposits and potentially contains critical information on the metallogenesis and its geodynamic setting. We, therefore, conducted geochemical analyses of amphibolite and metasedimentary rocks of this formation in the core of the Gamsberg fold, the results of which shed new light on the plate tectonic processes after deposition of the sedimentary exhalative ore. Major elements previously used for the characterisation of the amphibolite and the discrimination of the plate tectonic setting of its protolith had been mobilised during retrograde metamorphic overprint and are thus of little tectonic significance. More informative are certain trace elements: The amphibolite shows a strong depletion in Nb, Ta and P, typical of subduction-related magmatism, whereas exceptionally strong enrichment in mobile elements like Rb and Ba indicate the participation of continental material (crust/sediment) in the enrichment of the mantle wedge. This is in perfect agreement with existing U-Pb age data, which attest formation of the mafic metavolcanic rocks of the Koeris Formation at the very end of the Okiepian orogenesis (1 210 to 1 180 Ma), when subduction was terminated. Generally, very high Zn and Pb contents speak for metasomatic interaction of the Koeris Formation with the Zn-and Pb-rich Gamsberg deposit prior to peak metamorphism during the Klondikean orogeny (1 040 to 1 020 Ma). The fact that especially the immobile trace elements (e.g. Nb, Ta) in all metasedimentary rocks mirror the chemical characteristics of the metavolcanic rocks indicates local amphibolite detritus as a main source of the sediments.
We conclude that the metamorphic volcano-sedimentary sequence of the Koeris Formation is not, as previously assumed, the product of a large back-arc basin but was deposited in response to tectonic uplift in a small-scale intra- or inter-montane basin at the very end of the Okiepian orogeny. The thick amphibolite layers concentrated within this topographic depression may have played a crucial role in the conservation of the underlying ore. Therefore, the occurrence of the Koeris Formation may indicate favorable locations for further exploration.
