Near-field chipless-RFID system with high data capacity for security and authentication applications

A high data capacity chipless radio frequency identification (chipless-RFID) system, useful for security and authentication applications, is presented in this paper. Reading is based on the near-field coupling between the tag, a chain of identical split-ring resonators (SRRs) printed on a (typically flexible) dielectric substrate (e.g., liquid crystal polymer, plastic, and paper), and the reader. Encoding is achieved by the presence or absence of SRRs at predefined (equidistant) positions in the chain, and tag identification (ID) is based on sequential bit reading. Namely, the tag must be longitudinally displaced, at short distance, over the reader, a microstrip line loaded with an SRR and fed by a harmonic signal. By this means, the harmonic signal is amplitude modulated, and the (ID) code is contained in the envelope function, which can be obtained by means of an envelope detector. With this system, tag reading requires proximity with the reader, but this is not an issue in many applications within the domain of security and authentication (e.g., secure paper for corporate documents and certificates). Several circularly shaped 40-bit encoders (implemented in a commercial microwave substrate), and the corresponding reader, are designed and fabricated as proof-of-concept demonstrators. Strategies for programming the tags and a first proof-of-concept chipless-RFID tag fabricated on plastic substrate through inkjet printing are included in this paper

Rapid changes in anterior pituitary cell phenotypes in male and female mice after acute cold stress

Producción CientíficaThe anterior pituitary (AP) is made of five different cell types. The relative abundance and phenotype of AP cells may change in different physiological situations as an expression of pituitary plasticity. Here, we analyze in detail the phenotype of mouse corticotropes and the effects of acute cold stress on AP cell populations. The hormone content and the expression of hypothalamic-releasing hormone (HRH) receptors in all the five AP cell types were studied in the male and female mice at rest and after a 30-min cold stress. Expression of HRH receptors was evidenced by imaging the single-cell cytosolic Ca2+ responses in fura-2-loaded cells. Hormone contents were studied by multiple, simultaneous immunofluorescence of all the five hormones. Corticotropes displayed a striking sexual dimorphism, even in the resting condition. Male corticotropes showed the orthodox phenotype. They were monohormonal, storing only ACTH, and monoreceptorial, responding only to CRH. In contrast, female corticotropes were made of about equal parts of orthodox cells and multifunctional cells, which co-stored additional AP hormones and expressed additional HRH receptors. Cold stress did not modify the number of ACTH containing cells, but, according to immunostaining, it increased the relative abundance of other AP cell types at the expense of the pool of cells storing no hormones. Cold stress also modified the response to CRH and other HRHs. Most of these phenotypical changes presented a strong sexual dimorphism. These results indicate that pituitary plasticity is even larger than previously thought.Fondo de Investigaciones Sanitarias (grant FIS03/1231)Ministerio de Ciencia, Innovación y Universidades (grants BFU-2004-02765/BFI, BFU2005-02078 and BFU2007-60157

Influence of musculotendon geometry variability in muscle forces and hip bone-on-bone forces during walking

Inverse dynamics problems are usually solved in the analysis of human gait to obtain reaction forces and moments at the joints. However, these actions are not the actual forces and moments supported by the joint structure, because they do not consider the forces of the muscles acting across the joint. Therefore, to analyse bone-on bone forces it is necessary to estimate those muscle forces. Usually, this problem is addressed by means of optimization algorithms. One of the parameters required to solve this problem is the musculotendon geometry. These data are usually taken from cadavers or MRI data from several subjects, different from the analysed subject. Then, the model is scaled to the subject morphology. This procedure constitutes a source of error. The goals of this work were two. First, to perform a sensitivity analysis of the influence of muscle insertion locations on the muscle forces acting on the hip joint and on the hip joint bone-on-bone forces. Second, to compare the hip joint bone-on-bone forces during gait cycle obtained through muscle insertion locations taken from a musculoskeletal model template and a scaling procedure to those obtained from a subject-specific model using an MRI of the subject. The problem was solved using OpenSim. Results showed that anatomical variability should be analysed from two perspectives. One the one hand, throughout the gait cycle, in a global way. On the other hand, at a characteristic instant of the gait cycle. Variations of ±1 cm in the position of the attachment points of certain muscles caused variations of up to 14.21% in averaged deviation of the muscle forces and 58.96% in the peak force in the modified muscle and variations up to 57.23% in the averaged deviation of the muscle force and up to 117.23% in the peak force in the rest of muscles. Then, the influence of that variability on muscle activity patterns and hip bone-on-bone forces could be described more precisely. A biomechanical analysis of a subject-specific musculoskeletal model was carried out. Using MRI data, variations up to 5 cm in the location of the insertion points were introduced. These modifications showed significant differences between the baseline model and the customized model: within the range [-12%, 10%] for muscle forces and around 35% of body weight for hip bone-on-bone forces.Ministerio de Economía, Industria y Competitividad DPI2016-80796-P

Near-field chipless-RFID system with erasable/programmable 40-bit tags inkjet printed on paper substrates

In this letter, a chipless radio frequency identification (chipless-RFID) system with erasable/programmable 40-bit tags inkjet printed on paper substrates, where tag reading proceeds sequentially through near-field coupling, is presented for the first time. The tags consist of a linear chain of identical split ring resonators (SRRs) printed at predefined and equidistant positions on a paper substrate, and each resonant element provides a bit of information. Tag programming is achieved by cutting certain resonant elements, providing the logic state "0" to the corresponding bit. Conversely, tags can be erased (all bits set to "1") by short circuiting those previously cut resonant elements through inkjet. An important feature of the proposed system is the fact that tag reading is possible either with the SRR chain faced up or faced down (with regard to the reader). To this end, two pairs of header bits (resonators), with different sequences, have been added at the beginning and at the end of the tag identification chain. Moreover, tag data storage capacity (number of bits) is only limited by the space occupied by the linear chain. The implementation of tags on paper substrates demonstrates the potential of the proposed chipless-RFID system in secure paper applications, where the necessary proximity between the reader and the tag, inherent to near-field reading, is not an issu

Estrategias discursivas para la espectacularización : miradas sobre la Gran Recesión en los premios World Press Photo

Este artículo analiza las fotografías premiadas en los premios World Press Photo entre 2008 y 2013 sobre la crisis financiera de 2008. Nuestros objetivos se centran en analizar la incidencia de este tema en el concurso; en examinar la representación que se realiza de este tema a nivel formal y discursivo, y en observar las diferencias en la representación que se producen cuando entra en juego la narrativa fotográfica, a partir del análisis de las dos modalidades diferentes que ofrece el concurso: la fotografía individual (single) y la serie (story). Los resultados constatan una baja incidencia de este tema en el concurso, un predominio de la concepción de la representación como espectáculo, especialmente en las imágenes individuales frente a las series, que consiguen activar a través de mecanismos narrativos una lectura más reflexiva de las imágenes.Aquest article analitza les fotografies premiades en els World Press Photo entre 2008 i 2013 sobre la crisi financera de 2008. Els nostres objectius se centren a analitzar la incidència d'aquest tema en el concurs, a examinar la representació que es realitza d'aquest tema formalment i discursivament, i a observar les diferències en la representació que es produeixen quan entra en joc la narrativa fotogràfica a partir de l'anàlisi de les dues modalitats diferents que ofereix el concurs, la fotografia individual (single) i la sèrie (story). Els resultats constaten una baixa incidència d'aquest tema en el concurs y un predomini de la concepció de la representació com a espectacle, especialment en les imatges individuals enfront de les sèries, que aconsegueixen activar, a través de mecanismes narratius, una lectura més reflexiva de les imatges.This article analyses winning photographs on the 2008 financial crisis at the World Press Photo (WPP) Contest between 2008 and 2013. Our aim is to analyse the presence of this issue in the contest itself; its depiction in formal and discursive terms; and the differences in how it is depicted when a photographic narrative is involved, based on an analysis of two different classifications established by the WPP contest: the individual photograph ("single pictures") and the series ("stories"). The results show a low incidence of this issue in the contest, and a predominance of the idea of representation as spectacle, especially in the single pictures rather than the stories, which succeed in employing narrative strategies to elicit a more reflective reading of the images.Anàlisi is a science journal published by the Journalism and Communication Sciences Department of the Autonomous University of Barcelona (UAB).

Widespread distribution and altered pain processing in head and neck cancer survivors at long‑term after treatment

Funding for open access publishing: Universidad de Granada/CBUAPurposeRadiotherapy (RT) treatment in head and neck cancer (HNC) patients may induce long-term sequels as pain, which nowadays is not fully understand. Therefore, there is a need of characterization of pain features in HNC to enhance after oncology treatment management. Head and neck cancer survivors develop chronic pain after radiotherapy treatment. The purpose of the current study is to evaluate the presence of pain, pain distribution, and pain processing by means of patient reported outcomes and quantitative sensory testing.MethodsPain pressure threshold (PPT), temporal summation (TS), Brief Pain Inventory (BPI), Widespread Pain Index (WPI), The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire, and EuroQol5D5L were assessed in 20 head and neck cancer survivors (sHNC) and 20 health-related sex and age-matched controls.ResultsThe sHNC present lower PPT values in both the affected and non-affected side than did the healthy controls, especially in the widespread pain in the body, an altered TS in both affected and non-affected side and lower scores in quality of life and arm dysfunction.ConclusionsFollowing radiotherapy treatment after 1 year, sHNC present widespread pain, hypersensitivity in the radiated area, altered pain processing, upper limb affection, and a QoL diminution. These data provide evidence that a peripheral and central sensitization is happening in sHNC. Future efforts should focus on preventing pain after oncologic treatment. The comprehension about pain and its features in sHNC enhance health professional understanding and allows to tailor an optimal patient-targeted pain treatment.Universidad de Granada/CBU
