This paper addresses the conservation status of spectacled bear Tremarctos ornatus in northern Andes (Venezuela, Colombia and Ecuador) by analysing degree range fragmentation estimating habitat availability. From satellite images we constructed maps remnant blocks, consisting Andean forest páramo (high elevation shrublands grassland) ecosystems. information was overlain with a road map to determine potential isolation populations, human accessibility model used estimate core area each block....

Abstract The spectacled bear (Ursidae: Tremarctos ornatus) is an emblematic umbrella species and one of the top carnivores in Andean mountains. It also listed as vulnerable by IUCN endangered CITES. We analyzed genetic structure this nine geographical regions representing three Cordilleras Colombia. sequenced six mitochondrial genes 115 bears; a subset these specimens (n = 61) were genotyped at seven nuclear microsatellites. addressed objectives: 1) determine diversity historical demographic...

Abstract Knowledge of reproduction in wild Andean bears ( Tremarctos ornatus ) is scarce. Here we provide novel information about litter size, birth timings, courtship and multi-generational groups a population the Chingaza massif Colombia. Pregnant females, mothers with cubs, estimated times, size were registered through camera trapping at (Colombia) between 2011 2016. A total 34 independent records reproductive female obtained. Twenty-eight (28) different females recognized by external key...

Identification of Andean bear (Tremarctos ornatus) specimens is essential for obtaining demographic estimates their populations. Camera traps are a noninvasive tool that allows such identification. The efficiency using photographic or video records identifying this species in wild population Colombia was compared. A total 18 camera were operated from November 2011 through 2013; each sample station included single at 0.6 m height, with bait placed 2 front it 1.5 height. Four key external...

Describes a networked FPGA-based implementation of the FAST (Flexible Adaptable-Size Topology) architecture, an artificial neural network (ANN) that dynamically adapts its size. Most ANN models base their ability to adapt problems on changing strength interconnections between computational elements according given learning algorithm. However, constrained interconnection structures may limit such ability. Field programmable hardware devices are very well adapted for ANNs with in-circuit...

The impact of immunosuppression in solid organ transplant recipients with SARS-CoV-2 infection is unknown. knowledge about the behavior different schemes clinical outcomes scarce. This study aimed to determine risk death kidney COVID-19 under two immunosuppression. We describe our experience seven centers during first year pandemic before starting vaccination programs city Bogotá. Demographic characteristics, presentation, at and global treatment strategies were compared between recovered...

For decades, telemetry has provided large amounts of ecological information for several bear species; however, the Andean (Tremarctos ornatus), only three studies have available information.The use space this species was measured first time in Colombia with a male specimen tracked GPS telemetry.Bear locations (n= 348) were obtained between October and December 2013, during dry season.Our dry-season home range estimates nearest-neighbor convex-hull (K-NNCH, 24.62 km 2 ) kernel density...

Labomat 3 is a reconfigurable platform for teaching and research purposes developed by our laboratory. In this paper we describe in details the hardware software of board as well three application domains: logic design, computer architecture, codesign. The main features are: microprocessor associated with two mid-range FPGAs; set powerful tools going from real-time operating system to JavaVM; easy use design simulation tools, last but not least network interface. combination these makes...

The crossbreeding between advanced microprocessor design and Field Programmable Gate Arrays (FPGAs) has produced the Processor Array, code named FPPA. first integrated version been targeted for low power consumption parallel processing. FPPA is composed of a 10/spl times/10 array RISC microcontrollers offering up to 500 MIPS at 5 MHz processors (20 communications). very feature core processor results in 1 Watt whole makes it particularly interesting portable devices that require quite...

<h3>Background:</h3> SARS-CoV-2, the virus responsible for acute respiratory distress syndrome (ARDS). It can cause chronic inflammatory changes known as post-COVID (PCS), which are associated with autoimmune diseases such rheumatoid arthritis (RA), a polyarticular pathology generated by an overactivation of response, leading to activation different cytokine pathways that perpetuate systemic response. is therefore important understand impact on immune response in SARS-CoV-2 infected RA...

La vorágine sumerge en la selva amazónica colombiana durante el auge del caucho. Aborda temas como explotación de recursos naturales y comunidades indígenas, pérdida identidad cultural desplazamiento forzado, enfrentando brutalidad cauchera. Muestra cómo las compañías caucheras arrasan con sometiendo indígenas a condiciones inhumanas, medida que es devastada, los se ven obligados abandonar sus tradiciones modos ancestrales, generando una profunda reflexión sobre consecuencias colonización...

Abstract Objective To identify prognostic markers by applying machine learning strategies to the feature selection. Methods An observational, retrospective, multi-center study that included hospitalized patients with a confirmed diagnosis of COVID-19 in three hospitals Colombia. Eight were applied select prognostic-related characteristics. logistic regression models built from each set variables and predictive ability outcome was evaluated. The primary endpoint transfer intensive care or...
