Application of a seismic network to baleen whale call detection and localization in the Panama basin-a Bryde's whale example.

Baleen whales use sounds of various characteristics for different tasks and interactions. This study focuses on recordings from the Costa Rica Rift, in the Eastern Tropical Pacific Ocean, made by 25 ocean-bottom seismographs and a vertical array of 12 hydrophones between January and February 2015. The whale calls observed are of two kinds: more commonly, repetitive 4-5 s-long signals separated into two frequency bands centered at ∼20 and ∼36 Hz; less commonly, a series of ∼0.

How to fill the biodiversity data gap: Is it better to invest in fieldwork or curation?

Data gaps and biases are two important issues that affect the quality of biodiversity information and downstream results. Understanding how best to fill existing gaps and account for biases is necessary to improve our current information most effectively. Two current main approaches for obtaining and improving data include (1) curation of biological collections, and (2) fieldwork.

Lithospheric delamination as the driving mechanism of intermediate-depth seismicity in the Bucaramanga Nest, Colombia.

The Bucaramanga nest (BN) is an area of exceptionally strong intermediate-depth seismicity localized in a narrow zone at 150-170 km depth beneath the continental plate in Colombia. To explain the very unusual mantle seismicity cluster in this area, we built a seismic velocity model in the vicinity of BN with the use of local earthquake tomography and developed a numerical hydromechanical model. Our seismic model shows a strong high-velocity anomaly at 130-167 km coinciding with the BN seismicity.

Morphological analysis of plasma electrolytic oxidation coatings formed on Ti6Al4V alloys manufactured by electron beam powder bed fusion.

This study investigates and compares plasma electrolytic oxidation (PEO) coatings produced on wrought Ti6Al4V alloy substrates with those resulting from electron beam powder bed fusion (PBF-EB). For a duration of 1000 s, a phosphate/silicate electrolyte with a current density of 50 A/cm was employed to fabricate the coatings. Surface and polished cross-sections of the coated specimens underwent SEM and X-ray diffraction (XRD) analyses.

Visibility Graph Analysis of the Seismic Activity of Three Areas of the Cocos Plate Mexican Subduction Where the Last Three Large Earthquakes ( > 7) Occurred in 2017 and 2022.

The understanding of the dynamical behavior of seismic phenomena is currently an open problem, mainly because seismic series can be considered to be produced by phenomena exhibiting dynamic phase transitions; that is, with some complexity. For this purpose, the Middle America Trench in central Mexico is considered a natural laboratory for examining subduction because of its heterogenous natural structure. In this study, the Visibility Graph method was applied to study the seismic activity of three regions within the Cocos plate: the Tehuantepec Isthmus, the Flat slab and Michoacan, each one with a different level of seismicity.

Tsallis -Statistics in Seismology.

Non-extensive statistical mechanics (or -statistics) is based on the so-called non-additive Tsallis entropy. Since its introduction by Tsallis, in 1988, as a generalization of the Boltzmann-Gibbs equilibrium statistical mechanics, it has steadily gained ground as a suitable theory for the description of the statistical properties of non-equilibrium complex systems. Therefore, it has been applied to numerous phenomena, including real seismicity.

Additive manufacturing of Ti6Al4V alloy via electron beam melting for the development of implants for the biomedical industry.

Additive Manufacturing (AM) or rapid prototyping technologies are presented as one of the best options to produce customized prostheses and implants with high-level requirements in terms of complex geometries, mechanical properties, and short production times. The AM method that has been more investigated to obtain metallic implants for medical and biomedical use is Electron Beam Melting (EBM), which is based on the powder bed fusion technique. One of the most common metals employed to manufacture medical implants is titanium.

Global variation of seismic energy release with oceanic lithosphere age.

Variations in Mid Ocean Ridge seismicity with age provide a new tool to understand the thermal evolution of the oceanic lithosphere. The sum of seismic energy released by earthquakes during a time, and for an area, is proportional to its lithospheric age. Asthenospheric temperatures emerge on ridge centers with new crust resulting in high seismic activity; thus, the energy released sum is highest on the young lithosphere and decreases with age.

Extension of the thoracic spine sign as a diagnostic marker for thoracic trauma.

Introduction: The initial evaluation of patients with thoracic trauma remains a diagnostic challenge for surgery and emergency physicians. Chest sonography plays a key role in the approach for this group of patients, through extended and focused evaluation with trauma sonography (E-FAST).

Objectives: To establish the diagnostic performance of the extension of the thoracic spine sign using chest sonography in trauma to diagnose hemothorax and compare it with the gold standard test chest computed tomography (CT).

Recurrent Pneumonias in a Previously Healthy and Immunocompetent Young Adult: A Case Report Mounier-Kuhn Syndrome.

BACKGROUND Mounier-Kuhn syndrome is a rare clinical condition characterized by marked tracheal and bronchial dilatation. It is commonly associated with multiple respiratory infections due to the inability to mobilize secretions, chronic cough, and decline in lung capacity. Although it is a rare disease, the number of cases reported in the literature has increased, and physicians should be aware of its existence to be able to recognize and diagnose it.

Massive replica exchange Monte Carlo algorithm: a tool to access high pressure thermodynamics of hard systems.

We have explored the idea of producing the equilibrium equation of state, i.e. the pressure as a function of packing fraction, βP(φ), of a confined system up to very high pressures to yield the configuration that leads to the maximum packing fraction.

Breathing of the Nevado del Ruiz volcano reservoir, Colombia, inferred from repeated seismic tomography.

Nevado del Ruiz volcano (NRV), Columbia, is one of the most dangerous volcanoes in the world and caused the death of 25,000 people in 1985. Using a new algorithm for repeated tomography, we have found a prominent seismic anomaly with high values of the Vp/Vs ratio at depths of 2-5 km below the surface, which is associated with a shallow magma reservoir. The amplitude and shape of this anomaly changed during the current phase of unrest which began in 2010.

[Carbapenem-resistant Acinetobacter baumannii causing osteomyelitis and infections of skin and soft tissues in hospitals of Medellín, Colombia].

Introduction: Acinetobacter baumannii is an opportunistic bacterium which infects seriously ill patients, particularly those with ventilator-associated pneumonia and bacteremia. The emergence of resistance to carbapenem limits the options for the treatment of infections caused by this bacterium.

Objective: To describe the clinical and molecular characteristics of infections caused by carbapenem-resistant A.

[Molecular characterization of an outbreak of carbapenem-resistant Klebsiella pneumoniae in a tertiary care hospital in Medellín, Colombia].

Introduction: Resistance to carbapenems is considered to represent a serious threat to public health at the global level, since these antibiotics are one of the last therapeutic options for the treatment of multidrug-resistant bacteria. Molecular characterization of outbreaks due to resistant bacteria provides information that can be used in the design of infection control strategies.

Objective: To describe the molecular characteristics of an outbreak of carbapenem-resistant Klebsiella pneumoniae that occurred in a tertiary care hospital in Medellín in 2010-2011.

Distribution and trends of hematology and oncology research in Latin America: A decade of uncertainty.

Background: Although hematology and oncology research is a highly relevant and evolving field, research contributions by Latin American countries, apart from Brazil, remain unclear.

Methods: The authors performed a bibliometric analysis through a methodical search of the Latin American abstracts presented at 4 main hematology and oncology annual scientific meetings from 2000 to 2010. Latin American regional and national productivity was described through distribution and trend analyses; the subsequent percentage of full-text publications was also determined.
