Force induced stretched state: Effects of temperature

A model of self avoiding walks with suitable constraint has been developed to study the effect of temperature on a single stranded DNA (ssDNA) in the constant force ensemble. Our exact calculations for small chains show that the extension (reaction co-ordinate) may increase or decrease with the temperature depending upon the applied force. The simple model developed here which incorporates semi-microscopic details of base direction provide an explanation of the force induced transitions in ssDNA as observed in experiments.Comment: 5 pages, 8 figures, RevTex

¿Cómo la mediación pedagógica ayuda a resolver problemas de acoso escolar?

This research is about how pedagogical mediation influences in conflict resolution of school harassment, also known as bullying, was performed based on the ideas of prominent figures in the psychology field recognized worldwide such as Reuven Feuerstein and the Russian Lev Vygotsky. The first topic is pedagogical mediation, which highlights the importance of the mediator which may be the father, the teacher or a student with more experience. They carry out a process of intervention in the mediated student by selecting stimuli that allow them to transform the mindsets of the individual and to become actor and builder of his own experiences. This will allow for solving real problems in life by taking into account concepts such as mediated learning experience, direct exposure of the individual to the medium, the cognitive mediation and metacognitive as well as some criteria of mediation such as the intent, meaning and transcendence. The second theme is bullying, which is explained in detail in terms of what is the phenomenon, the circle of bullying, the actors who are the bullies, the victim and the witness, presenting characteristics of each of these actors. The third issue raises a series of strategies that allow children and young people to grow up confident and to avoid problems related to bullying, including avoiding telling their weaknesses to others. These strategies are suggested to parents to help them compensate and compete, to not lose sight of the actions of the school in order to protect children and youth from falling into the clutches of bullying.La investigación trata sobre cómo la mediación pedagógica incide en la resolución de problemas de acoso escolar, más conocido como bullying. Se realizó en base a los planteamientos de personajes destacados dentro del campo de la psicología reconocidos a nivel mundial como lo son Reuven Feuerstein y los postulados del ruso Lev Vygotsky. El primer tema la importancia del mediador, que puede ser el padre, el maestro o un estudiante con mayor experiencia. Ellos realizan un proceso de intervención en el estudiante, seleccionando los estímulos que permitan transformar las estructuras mentales del individuo para que se convierta en actor y constructor de sus propias experiencias que le llevaran a resolver problemas reales de su vida. Se toma en cuenta conceptos como la experiencia de aprendizaje mediado, la exposición directa del individuo al medio, la mediación cognitiva y metacognitiva al igual que algunos criterios de mediación como son el de intencionalidad, significado y la trascendencia. El segundo tema es el acoso escolar, donde se explica detalladamente en qué consiste el fenómeno. Se explica el círculo de acoso escolar y sus actores que son el acosador, la víctima y el testigo, presentando características de cada uno de estos actores. El tercer tema plantea una serie de estrategias para que los niños y jóvenes crezcan seguros de sí mismos y puedan evitar problemas relacionados con el acoso escolar

Time-symmetric fluctuations in nonequilibrium systems

For nonequilibrium steady states, we identify observables whose fluctuations satisfy a general symmetry and for which a new reciprocity relation can be shown. Unlike the situation in recently discussed fluctuation theorems, these observables are time-reversal symmetric. That is essential for exploiting the fluctuation symmetry beyond linear response theory. Besides time-reversal, a crucial role is played by the reversal of the driving fields, that further resolves the space-time action. In particular, the time-symmetric part in the space-time action determines second order effects of the nonequilibrium driving.Comment: 4 page

Una biblioteca sin libros ni revistas

Sección: Las bibliotecas cuentan¿Os sorprende este titular, verdad?. A mí también me dejó sorprendida cuando quedó terminado hace tres años el nuevo edificio del Instituto al que pertenezco y se creó el puesto que hoy ocupo, como responsable de la biblioteca. No, no existen libros ni revistas en la sala denominada biblioteca. Entonces, ¿qué funciones realizo?N

Correlations and preliminary validation of laboratory asphalt binder and HMA reflective cracking resistance to field performance of in-service highway sections

Reflective cracking is one of the dominant distress modes occurring when hot-mix asphalt (HMA) overlays are placed over existing cracked flexible and/or jointed rigid pavements. Various tests have been conducted in the literature for measuring, characterizing, and quantifying the cracking resistance potential of HMA mixes in the laboratory. Asphalt-binder is one of the key constituent elements that significantly influences and controls the fracture behavior and cracking performance of hot-mix asphalt (HMA), both in the laboratory and field. In particular, the low-temperature rheological properties of the asphalt-binders are very critical in terms of improving the HMA fracture properties in the laboratory and ultimately mitigating cracking in the field. The Elastic Recovery (ER) and Bending Beam Rheometer (BBR) are the most widely used laboratory test methods for evaluating and quantifying the asphalt-binder behavior at low temperatures, mostly using the ductility (ER), stiffness (S), and m-value parameters. Some cracking test related to mixes have been studied, both of dynamic and monotonic loading modes. However, one key challenge with most of these laboratory tests is correlations and validation with field performance data. Quite often, field data availability is a challenge or otherwise, needs costly long-term performance monitoring. Using the Texas flexible pavements and overlays database, namely the Texas Data Storage System (DSS), as the data source, this study was conducted to correlate and preliminarily validate the asphalt-binder low-temperature properties (measured using the BBR and ER tests) and laboratory monotonic-loading overlay tester (OT) to the field crack (reflective) performance of in-service highway sections.MaestríaMagister en Ingeniería Civi

Should I Stay or Should I Go: The Impact of Crossing Migrants in local communities in Mexico

The interactions between migrants and Mexican local communities have positive and negative outcomes. A report by Human Rights First found that more than 630 violent crimes against asylum seekers were reported in the first few months of the “Remain in Mexico” policy. Still, some migrants have been able to assimilate and stay in Mexico, particularly in large cities such as Tijuana, Baja California and Ciudad Juarez, Chihuahua. This research project combines qualitative data collected through interviews with local NGOs between September 2020 to February 2021 and secondary research data. It focuses on the living conditions of migrants who have stayed in Mexico. Particularly, the study looks into the context that these migrants face when crossing, transiting, and establishing in local Mexican communities, either because they are in the process of waiting for their asylum seeking process to take place in the United States or because they decide to definitely stay in Mexico. In the project, I look at the effects of the “Remain in Mexico” policy and the new challenges migrants have faced since the start of the Covid-19 pandemic. Overall, the project finds that migrants in Mexico are exposed to continuous violence, both from the state, from criminal groups, and even from groups that are in charge of their protection. This context increases the vulnerability of migrants and reduces their capacity to access resources that are already scarce. This situation got exacerbated after the start of the pandemic, with the closure of the Southern border. Further research will focus on the interaction between migrant groups and local communities and the violence that emerges from these exchanges
