ENTORNOS PARA EL DESARROLLO DE APLICACIONES MÓVILES

El esquema de desarrollo de las aplicaciones móviles es una tecnología que se encuentra en auge, aun cuando los dispositivos móviles existen desde hace más de 15 años, la perspectiva de los visionarios de las tecnologías de la información, y la disminución de costos de fabricación, ha permitido que tales dispositivos estén al alcance de los usuarios. Aun cuando parte de la teoría para el desarrollo de aplicaciones de esta tipo ya se encuentra plasmada en diversos documentos, se considera relevante plantear los nuevos usos que pueden darse a esta tecnología; lo anterior derivado por los avances tecnológicos: características, rendimiento, esquemas de comunicación, sistemas operativos, lenguajes de programación, almacenamiento y recuperación de datos, entre otras

Are 'STEM from Mars and SSH from Venus'?: Challenging disciplinary stereotypes of research's social value

There is a reasonably settled consensus within the innovation community that science, technology, engineering and mathematics (STEM) research is more 'useful' to societies than other types of research, notably social sciences and humanities (SSH) researchOlmos-Peñuela, J.; Benneworth, P.; Castro-Martinez, E.

Biomimetics of microducts in three-dimensional bacterial nanocellulose biomaterials for soft tissue regenerative medicine

The demand for solid organs is increasing worldwide, regenerative medicine aims to develop organs that can replace their human counterparts. In this regard, this study describes a novel biomimetic-based methodology for the incorporation of microducts in 3D bacterial nanocellulose (BNC-3D) biomaterials. Although BNC is a biomaterial that has been used as a scaffold for cell culture purposes, it does not have the microduct structure that solid organs required to maintain cell viability. This study aims to biomimicry the microduct structure (blood vessels) in BNC using a corroded porcine kidney in epoxy resin during BNC synthesis. The resin mold was incorporated into the biological process of producing BNC-3D. After the BNC fermentation, the resin was removed using a novel method (acid hydrolysis) to expose the blood vessels constructs. BNC-3D and BNC-3D with microducts (BNC-3DM) were analyzed using electronic microscopy, infrared analysis, thermogravimetric and biological analysis. Results show that biomaterials biomimicry the blood vessels of the reference organ, moreover, the BNC chemical and morphological properties of BNC was not affected in the biomimetic process. Regarding cell behavior, cell viability was not affected by the incorporation of the microducts, and it was proven that viable cells adhere to the microducts surface, reproducing their shape and migrate into the biomaterial up to 245 mu m for 8 days of culture. To conclude, the data demonstrate the potential of biomimetic in BNC for regenerative medicine, in which the microducts transport fluids (blood, nutrients, and waste products) from and to engineered solid organs via animal counterparts. Graphic abstract The graphical abstract represents the structural modification of bacterial nanocellulose (BNC) with the inclusion of microducts and microporosities. Furthermore, it represents the usefulness of the microducts in future applications, where, they can be used for nutrients inlet to feed the cells and to remove the wastes from the developed tissue, same as do the blood vessels.

Runs versus Lemons: Information Disclosure and Fiscal Capacity

We study the optimal use of disclosure and fiscal backstops during financial crises. Providing information can reduce adverse selection in credit markets, but negative disclosures can also trigger inefficient bank runs. In our model, governments are thus forced to choose between runs and lemons. A fiscal backstop mitigates the cost of runs and allows a government to pursue a high disclosure strategy. Our model explains why governments with strong fiscal positions are more likely to run informative stress tests, and, paradoxically, how they can end up spending less than governments that are more fiscally constrained

For which infants with viral bronchiolitis could it be deemed appropriate to use albuterol, at least on a therapeutic trial basis?

Although there is increasing evidence showing that infants with viral bronchiolitis exhibit a high degree of heterogeneity, a core uncertainty shared by many clinicians is with regard to understanding which patients are most likely to benefit from bronchodilators such as albuterol. Based on our review, we concluded that older infants with rhinovirus (RV) bronchiolitis, especially those with a nasopharyngeal microbiome dominated by Haemophilus influenzae; those affected during nonpeak months or during non-respiratory syncytial virus (RSV) predominant months; those with wheezing at presentation; those with clinical characteristics such as atopic dermatitis or a family history of asthma in a first-degree relative; and those infants infected with RSV genotypes ON1 and BA, have the greatest likelihood of benefiting from albuterol. Presently, this patient profile could serve as the basis for rational albuterol administration in patients with viral bronchiolitis, at least on a therapeutic trial basis, and it could also be the starting point for future targeted randomized clinical trials (RCTs) on the use of albuterol among a subset of infants with bronchiolitis

An approach to emotion recognition in single-channel EEG signals: a mother child interaction

In this work, we perform a first approach to emotion recognition from EEG single channel signals extracted in four (4) mother-child dyads experiment in developmental psychology -- Single channel EEG signals are analyzed and processed using several window sizes by performing a statistical analysis over features in the time and frequency domains -- Finally, a neural network obtained an average accuracy rate of 99% of classification in two emotional states such as happiness and sadness20th Argentinean Bioengineering Society Congress, SABI 2015 (XX Congreso Argentino de Bioingeniería y IX Jornadas de Ingeniería Clínica)28–30 October 2015, San Nicolás de los Arroyos, Argentin

The effect of facial ageing on forensic facial image comparison

Facial appearance changes over time as people age. This poses a challenge for individuals working in forensic settings whose role requires them to match the identity of face images. The present research aimed to determine how well an international sample of forensic facial examiners could match faces with a substantial age gap. We tested a sample of 60 facial examiners, 23 professional teams and 81 untrained control participants. Participants matched pairs of photographs with a 10–30-year age gap between the images. Participants also estimated the ages of the faces. On the matching task, individual professionals and teams outperformed controls and made fewer high confidence errors. On the age estimation task, there was no advantage for professionals relative to controls. Our results suggest that forensic facial examiners can tolerate substantial age differences between adult faces when performing comparisons, but this advantage does not extend to accurate age estimation
