Authors: Fernández Droguett Francisca 
Published: March 2020

The objective of the present article is to characterize the sociocultural profile of foreign indigenous women deprived of liberty in the regions of Arica-Parinacota, Tarapacá and Antofagasta, in northern Chile. For this, a qualitative investigation was carried out by conducting semi-structured interviews. As for the results, most of the women come from the regions of Puno, Peru, and Cochabamba, Bolivia; they correspond to the Aymara and Quechua populations, respectively; they carry out commercial activities related to cooking, cleaning, sewing, buy-and-sale of products; incarcerated for the crime of drug trafficking. Some of the conclusions raised by the research are the need to recognize self-identification and territorial origin as criteria to ensure indigenous quality in Chilean prisons.

Published: March 2020

The purpose of the article is to carry out a theoretical analysis regarding the conceptual bases and the approaches that have been built around Health Promotion (HP), with the purpose of identifying similarities, divergences, advances and opportunities to strengthen the coherent theoretical position with the philosophy of Health Promotion, from a positive, purposeful, proactive and innovative vision promoted from within Costa Rica. Methodologically, content analysis is used, given the eminently theoretical approach of the article. The object of study is the conceptual and theoretical development of HP and some of its visions. The article discusses some theoretical currents linked to the topic, including the definition forwarded by PAHO in its 1986 Otawa Charter, healthy lifestyles, and the ability to enhance human development, to then emphasize the positive vision that is promoted by the Health Promotion Rectory Model of the Ministry of Health of Costa Rica; reference is made to differences existing between HP and prevention in general, including those related to rights and needs. The work concludes with the importance of the subject in question, its contributions and relevance to improve the implementation of the HP model in the Región de Occidente of Costa Rica (Costa Rica’s Western Region), in the first instance, with possible dissemination to other regions or even other countries.
DIRECT EXPONENT AND SCALAR MULTIPLICATION TRANSFORMATIONS OF MDS MATRICES: SOME GOOD CRYPTOGRAPHIC RESULTS FOR DYNAMIC DIFFUSION LAYERS OF BLOCK CIPHERS
Authors: Luong Tran Thi , Cuong Nguyen Ngoc 
Published: March 2020

Abstract: MDS (Maximum Distance Separable) matrices have an important role in the design of block ciphers and hash functions. The methods for transforming an MDS matrix into other ones have been proposed by many authors in the literature. In this paper, some new results about direct exponent and scalar multiplication transformations are given including the preservation of good cryptographic properties (the coefficient of fixed points and involutory property) of MDS matrices and other important cryptographic properties obtained from studying equivalence relations based on these transformations. An estimation of the number of MDS matrices over is also presented. In addition, these results are shown to be an important theoretical basis for building efficient dynamic diffusion layer algorithms for block ciphers.

Published: March 2020

ABSTRACTWe use the eikonal equation-based seismic travel-time tomography method to image the source areas of the 2008 Wenchuan earthquake and the 2013 Lushan earthquake in the Longmenshan fault zone. High-resolution VP and VS models are obtained by inverting 75,686 P-wave and 74,552 S-wave travel times of local earthquakes during the period from 2009 to 2018. The tomographic models reveal strong crustal velocity heterogeneities in the study area. A significant velocity contrast exists across the Longmenshan fault zone: The western Songpan–Ganzi block is a high-velocity body, whereas the eastern Sichuan basin is a low-velocity anomaly. The hypocenter of the 2008 Wenchuan earthquake is between a high-velocity and a low-velocity anomaly. Beneath the Wenchuan mainshock, there is a significant low-velocity structure in the lower crust. The 2013 Lushan earthquake occurred in rocks associated with a high-velocity anomaly. A distinct low-velocity zone with low seismicity is imaged between the 2008 Wenchuan earthquake and the 2013 Lushan earthquake, where the crustal ductile deformation is likely to occur. The Baoxing complex to the northwest of the Lushan hypocenter exhibits as a high-velocity anomaly, which may be a carrier of stress accumulation and more prone to seismic activities in the future.
Earthquake Magnitude and Lg Q Variations between the Grenville and Northern Appalachian Geologic Provinces of Eastern Canada
Authors: Claire Perry H. K. , Bent Allison L. , McNamara Daniel E. , Crane Stephen , Kolaj Michal 
Published: March 2020

ABSTRACTThis article assesses the ability of regionally specific, frequency-dependent crustal attenuation (1/Q) to reduce mean magnitude discrepancies between seismic stations in the northern Appalachian and Grenville provinces (NAP and GP) of Canada. LgQ(f) is an important parameter in ground-motion models used in probabilistic seismic hazard analysis. Discrepancies in regional magnitude estimates have long been noted to exist between stations in the two provinces for common event origins. Such discrepancies could arise from systematic site condition variations between the geologic provinces or from varying crustal attenuative properties. To evaluate the effect of frequency-dependent anelastic attenuation, LgQ(f) on estimated magnitudes, we analyze Lg amplitudes from &gt;6000 waveforms recorded by Grenville and northern Appalachian receivers from 420 natural earthquakes of MN magnitude 3–5.6. Waveform analysis is strictly limited to analyst-reviewed, vertical-component waveforms in which Lg is clearly identified, ensuring that the datasets exhibit dominant, high-frequency energy in the Lg velocity window. LgQ(f) is found to be higher in the GP than in the northern Appalachians. In the Grenville, Q(f)=761(±145)f0.25(±0.014), and in the northern Appalachians, attenuation is higher: Q(f)=506(±172)f0.33(±0.310). Earthquake magnitude determined using the peak amplitude of the Lg phase (mbLg) for eastern Canada is corrected to incorporate the frequency-dependent, regionally specific LgQ(f) determined in this study. Using the new LgQ(f) values diminishes and nearly resolves magnitude discrepancies between the provinces. Correcting regional magnitude discrepancies between provinces is critical for reliable regional seismic hazard estimates because magnitude error in a particular region could lead to increased uncertainty in seismic hazard models.
Detecting Site Resonant Frequency Using HVSR: Fourier versus Response Spectrum and the First versus the Highest Peak Frequency
Authors: Zhu Chuanbin , Cotton Fabrice , Pilz Marco 
Published: March 2020

ABSTRACTIn this investigation, we examine the uncertainties using the horizontal-to-vertical spectral ratio (HVSR) technique on earthquake recordings to detect site resonant frequencies at 207 KiK-net sites. Our results show that the scenario dependence of response (pseudospectral acceleration) spectral ratio could bias the estimates of resonant frequencies for sites having multiple significant peaks with comparable amplitudes. Thus, the Fourier amplitude spectrum (FAS) should be preferred in computing HVSR. For more than 80% of the investigated sites, the first peak (in the frequency domain) on the average HVSR curve over multiple sites coincides with the highest peak. However, for sites with multiple peaks, the highest peak frequency (fp) is less susceptible to the selection criteria of significant peaks and the extent of smoothing to spectrum than the first peak frequency (f0). Meanwhile, in comparison to the surface-to-borehole spectral ratio, f0 tends to underestimate the predominant frequency (at which the largest amplification occurs) more than fp. In addition, in terms of characterizing linear site response, fp shows a better overall performance than f0. Based on these findings, we thus recommend that seismic network operators provide fp on the average HVSRFAS curve as a priority, ideally together with the average HVSRFAS curve in site characterization.
Maximum Earthquake Size and Seismicity Rate from an ETAS Model with Slip Budget
Authors: Marsan David , Tan Yen Joe 
Published: March 2020

ABSTRACTWe define a seismicity model based on (1) the epidemic-type aftershock sequence model that accounts for earthquake clustering, and (2) a closed slip budget at long timescale. This is achieved by not permitting an earthquake to have a seismic moment greater than the current seismic moment deficit. This causes the Gutenberg–Richter law to be modulated by a smooth upper cutoff, the location of which can be predicted from the model parameters. We investigate the various regimes of this model that more particularly include a regime in which the activity does not die off even with a vanishingly small spontaneous (i.e., background) earthquake rate and one that bears strong statistical similarities with repeating earthquake time series. Finally, this model relates the earthquake rate and the geodetic moment rate and, therefore, allows to make sense of this relationship in terms of fundamental empirical law (the Gutenberg–Richter law, the productivity law, and the Omori law) and physical parameters (seismic coupling, tectonic loading rate).

Background: Malignant pleural effusion is a common medical problem in patients with cancer. The survival of patients with malignant pleural effusion is generally poor. The objectives of our study were to reveal possible prognostic factors of malignant pleural effusion.Methods: Fifty-three consecutive patients, 34 male and 19 female patients of malignant pleural effusion diagnosed by pleural fluid positive for malignant cytology and/or pleural tissue positive for malignancy by thoracoscopy biopsy. Performance status by the Eastern Cooperative Oncology Group (ECOG) score and LENT score was calculated at the time of diagnosis. Median survival time was calculated using Kaplan-Meier analysis curve. Survival time was defined as the time from diagnosis to death or the last follow-up.Results: Most common cause of malignant pleural effusion was lung carcinoma 46 (86.79%). Adenocarcinoma was the most common 31 (58.5%) followed by NSCLC 10 (18.0%). Low, moderate and high-risk LENT score was found in 3 (5.7%), 35 (66%) and 15 (28.3%) respectively. The median survival time of pleural fluid sugar less than 20 were 3 months. The median survival time of LENT low, medium and high risk was 12 months, 5.2 months and 2.5 months respectively. The median survival time of patients with ECOG score of 1 and 4 was 6.5 months and 1 month respectively. Patients with bilateral pleural fluid had a mean survival time of 2 months.Conclusions: Adenocarcinoma lung is the most common etiology of malignant pleural effusion. The median overall survival time was 4 months. Higher ECOG score and LENT score are associated with shorter survival time.

This study aimed to investigate the community structure of sea cucumber in this region as one of the supporting information for the utilization and management of the resources. A survey was conducted by sweeping the target area, by walking and also snorkeling. The location where each sea cucumber found was marked using a GPS, the specimen was weighed, and some were preserved for species analysis. Water quality was measured at each location, while the substrate and vegetation were recorded. This study revealed different composition of species in the investigated area. As many as 8 species of sea cucumber were found, in which four were of genus Holothuria, three were of genus Stichopus and the rest were of genus Bohadschia. Species H. atra has the highest density. In general, the diversity index was relatively low (< 2), the evenness index was 0-81 indicating that the community was depressed. Certain species dominated at most of the investigated sites (0.50-1), and a low margalef index is 0-1.7. To conclude, the community structure of sea cucumber in Tual and Southeast Moluccas was in a depressed condition.
