Automated, Ultra-Sterile Solid Sample Handling and Analysis on a Chip
There are no existing ultra-sterile lab-on-a-chip systems that can accept solid samples and perform complete chemical analyses without human intervention. The proposed solution is to demonstrate completely automated lab-on-a-chip manipulation of powdered solid samples, followed by on-chip liquid extraction and chemical analysis. This technology utilizes a newly invented glass micro-device for solid manipulation, which mates with existing lab-on-a-chip instrumentation. Devices are fabricated in a Class 10 cleanroom at the JPL MicroDevices Lab, and are plasma-cleaned before and after assembly. Solid samples enter the device through a drilled hole in the top. Existing micro-pumping technology is used to transfer milligrams of powdered sample into an extraction chamber where it is mixed with liquids to extract organic material. Subsequent chemical analysis is performed using portable microchip capillary electrophoresis systems (CE). These instruments have been used for ultra-highly sensitive (parts-per-trillion, pptr) analysis of organic compounds including amines, amino acids, aldehydes, ketones, carboxylic acids, and thiols. Fully autonomous amino acid analyses in liquids were demonstrated; however, to date there have been no reports of completely automated analysis of solid samples on chip. This approach utilizes an existing portable instrument that houses optics, high-voltage power supplies, and solenoids for fully autonomous microfluidic sample processing and CE analysis with laser-induced fluorescence (LIF) detection. Furthermore, the entire system can be sterilized and placed in a cleanroom environment for analyzing samples returned from extraterrestrial targets, if desired. This is an entirely new capability never demonstrated before. The ability to manipulate solid samples, coupled with lab-on-a-chip analysis technology, will enable ultraclean and ultrasensitive end-to-end analysis of samples that is orders of magnitude more sensitive than the ppb goal given in the Science Instruments
Evaluación de la calidad de cocción y calidad sensorial de pasta elaborada a partir de mezclas de sémola de trigo y harina de quinua.
La pasta es un alimento de consumo masivo que posee varias ventajas: larga vida útil, aporta energía en la dieta y amplia aceptación por parte del consumidor. La quinua (Chenopodium quinoa willd) es un pseudo-cereal cuyo aprovechamiento se promueve por su buena calidad nutricional, por el potencial de producción y el fácil desarrollo del cultivo bajo diferentes condiciones ambientales con tecnologías sencillas. La pasta sustituida parcialmente con quinua puede representar beneficios sobre la salud y la nutrición de los consumidores, ya que éstas tendrían una mejor calidad nutricional comparada con la pasta comercial de 100% sémola de trigo. El presente estudio incluye el desarrollo tecnológico de productos con dos niveles de sustitución del 10% y 30%, con dos harinas de quinua correspondientes a las variedades Aurora y Blanca Jericó, cultivadas en Colombia, así como el análisis de la adición de dos agentes estructurantes: Carboximetil Celulosa (2%) y almidón de maíz pregelatinizado (9%). Las variables de respuesta en las pastas elaboradas fueron calidad de la pasta cruda (color, valor nutricional proximal, dureza/fracturabilidad y calidad microbiológica), calidad en la cocción (tiempo óptimo de cocción y degradación por liberación de almidón) y calidad de la pasta cocida (evaluación sensorial, propiedades mecánicas y biológicas). Los resultados mostraron que las pastas cumplen con los estándares tecnológicos exigidos en la legislación nacional y que son comparables con pastas comerciales de 100% sémola de trigo, ofreciendo una buena calidad nutricional y una buena calidad microbiológica. No se pudieron establecer diferencias en la calidad de las pastas elaboradas entre las dos variedades de quinua utilizadas, sin embargo, ciertas características mecánicas alcanzadas en las pastas elaboradas con quinua Blanca Jericó y carboximetil celulosa como agente estructurante, hacen considerar que estas variedades dulces cultivadas en Colombia resultan altamente promisorias. Definitivamente la calidad en la cocción y propiedades mecánicas son inferiores a las de pastas no sustituidas, con mayor liberación de almidón durante la cocción, pero con tiempos de cocción óptimos menores, sin embargo se mantienen en un nivel aceptable para su preparación. Aunque los indicadores bioquímicos evaluados en los pacientes no aumentaron ni descendieron, este estudio exploratorio indica que estas pastas sustituidas con quinua pueden ser utilizadas en dietas especiales, como en el caso de pacientes diabéticos./Abstract. Pasta is a staple food with some quality advantages like long shelf life, nutritional value at energy intake in diet and wide acceptance in market. Quinoa is a pseudo-cereal that resurged from ancestral customs, due to its good nutritional quality and its potential given by an easy development of the crop under different environmental conditions with simple technologies. Pasta replaced with quinoa can represent benefits on consumer health and nutrition, as it will have a better nutritional quality compared to the market pasta from 100% wheat semolina. This research includes study of technological products with two levels of replacement of 10% and 30 %, analyzing the sustitution with two varieties Aurora and Blanca Jericó, cultivated in Colombia, as well as the analysis of addition of two substitutes gluten as Carboximetil Cellulose (2%) and pregelatinized corn starch (9%). The quality of prepared pasta was assessed on uncooked pasta (colour, nutritional value proximal, hardness/fracturability and microbiological quality), on cooking (optimum time of cooking and degradation by release of starch) and on cooked pasta (sensory evaluation, mechanical and biological properties). Results showed that pasta had technological standards required in the national legislation and are comparable with commercial pasta 100% wheat semolina, offering a nutritional quality improved product and a good microbiological quality. Differences were unclear among treatments, although pastas prepared with quinoa Blanca Jericó and carboxymethyl cellulose as gluten substitute exhibited better mechanical properties. Even though quality of cooking and mechanical properties are lower in pastas with quinoa flour compared to pastas with wheat semolina, pastas with quinoa flour exhibited promissory characteristics for special diets.Abstract: Pasta is a staple food with some quality advantages like long shelf life, nutritional value at energy intake in diet and wide acceptance in market.

Evaluation of a Permutation-Based Evolutionary Framework for Lyndon Factorizations
String factorization is an important tool for partitioning data for parallel processing and other algorithmic techniques often found in the context of big data applications such as bioinformatics or compression. Duval’s well-known algorithm uniquely factors a string over an ordered alphabet into Lyndon words, i.e., patterned strings which arestrictly smaller than all of their cyclic rotations. While Duval’s algorithm produces a pre-determined factorization, modern applications motivate the demand for factorizations with specific properties, e.g., those that minimize the number of factors or consist of factors with similar lengths. In this paper, we consider the problem of finding an alphabet ordering that yields a Lyndon factorization with such properties. We introduce a flexible evolutionary framework and evaluate it on biological sequence data. For the minimization case, we also propose a new problem-specific heuristic, Flexi-Duval, and a problem-specific mutation operator for Lyndon factorization. Our results show that our framework is competitive with Flexi-Duval for minimization and yields high quality and robust solutions for balancing where no problem-specific algorithm is available

CHANG-ES IV: Radio continuum emission of 35 edge-on galaxies observed with the Karl G. Jansky Very Large Array in D-configuration, Data Release 1
We present the first part of the observations made for the Continuum Halos in
Nearby Galaxies, an EVLA Survey (CHANG-ES) project. The aim of the CHANG-ES
project is to study and characterize the nature of radio halos, their
prevalence as well as their magnetic fields, and the cosmic rays illuminating
these fields. This paper reports observations with the compact D configuration
of the Karl G. Jansky Very Large Array (VLA) for the sample of 35 nearby
edge-on galaxies of CHANG-ES. With the new wide bandwidth capabilities of the
VLA, an unprecedented sensitivity was achieved for all polarization products.
The beam resolution is an average of 9.6" and 36" with noise levels reaching
approximately 6 and 30 microJy per beam for C- and L-bands, respectively
(robust weighting). We present intensity maps in these two frequency bands (C
and L), with different weightings, as well as spectral index maps, polarization
maps, and new measurements of star formation rates (SFRs). The data products
described herein are available to the public in the CHANG-ES data release
available at www.queensu.ca/changes. We also present evidence of a trend among
galaxies with larger halos having higher SFR surface density, and we show, for
the first time, a radio continuum image of the median galaxy, taking advantage
of the collective signal-to-noise ratio of 30 of our galaxies. This image shows
clearly that a typical spiral galaxy is surrounded by a halo of magnetic fields
and cosmic rays.Comment: 70 pages, of which 35 pages present the data of each galax
Polyhydroxyalkanoate production from unexplored sugar substrates
Industrial-scale production of biopolymers is restricted by its elevated production costs in comparison with those associated with synthetic (no-biodegradable and no-biocompatible) polymers. In this study we tested for the first time two low-cost carbon substrates (i.e. carob pulp and fique juice) for lab-scale production of polyhydroxyalkanoate (PHA) with Bacillus megaterium. PHA detection and quantification was conducted by gas chromatography/mass spectrometry-selected ion monitoring (GC/MS-SIM). The results suggest that PHA production using carob pulp (from Hymenaea courbaril) may be as high as with sugar cane molasses. Moreover, it could serve for the synthesis of the most commercialized type of PHA (i.e. polyhydroxybutyrate; PHB) and/or other varieties (e.g. polyhydroxy-butyrate-co-valerate; PHBV) with different properties and potential applications
Factores de riesgo para hipoacusia asociados a alteraciones auditivas en neonatos ingresados a la Unidad de Cuidados Intensivos del Hospital Dr. Rafael Ángel Calderón Guardia, San José, Costa Rica, 2018-2019
Introducción: en Costa Rica, aproximadamente la mitad de los niños nacidos por año presenta factores de riesgo para hipoacusia, esto ocasiona pérdidas auditivas de diversa etiología que pueden manifestarse antes, durante o después del nacimiento. Lo anterior da lugar a resultados alterados en pruebas de tamizaje auditivo neonatal, tales como las emisiones otoacústicas y los potenciales evocados auditivos automatizados. Objetivo: se propuso determinar la relación entre los factores de riesgo para hipoacusia y las alteraciones auditivas en neonatos, a partir de referencias de ingreso a la Unidad de Cuidados Intensivos (UCI) y de la base de datos del TANU, entre los años 2018 y 2019, en el Hospital Dr. Rafael Ángel Calderón Guardia. Metodología: la investigación adoptó un enfoque cuantitativo. Se realizaron medidas de tendencia central y de dispersión, pruebas de independencia y correlación de Pearson, y un modelo de regresión logística. Resultados: existe una relación entre los factores de riesgo para hipoacusia y las alteraciones auditivas en el tamizaje. Se encontraron elementos significativos como anoxia, infecciones intrauterinas, síndromes, malformaciones asociadas a hipoacusia, ototóxicos, estadía en UCI mayor a cinco días, peso menor a 1500 g, edad en días e infecciones intrauterinas, los cuales predicen resultados de refiere en las pruebas de tamizaje. Conclusiones: es necesario llevar a cabo un seguimiento audiológico a los neonatos que presenten factores de riesgo para hipoacusia e implementar mejoras en cuanto al manejo de antecedentes y pruebas auditivas aplicadas
