Przeszłość i przyszłość są teraz… Kilka refleksji inspirowanych filmową adaptacją Szpitala przemienienia
Authors: Grodź Iwona
Published: April 2022

PAST AND FUTURE ARE NOW… A FEW REFLECTIONS ON HOSPITAL OF THE TRANSFIGURATION FILM DIRECTED BY EDWARD ŻEBROWSKI The text is an attempt to look again at the realistic novel of Stanisław Lem Hospital of the Transfiguration from 1948 (part of the trilogy of the Time Not Lost) and its adaptation directed by Edward Żebrowski. However, this is not a dissertation on the indicated story or film, but rather an essay inspired by the book and film in order to make more general reflections on changes related to the problems of the 21st century and anticipation of future events, and thus: a metaphor of the world as a prison hospital for people who are “sick in the soul” and reflections on the human body and its disabilities.

Published: April 2022

Este artículo describe diferentes opciones para crear servicios para los usuarios, destinados a promover la lectura y la transferencia de conocimiento favoreciendo la cooperación entre bibliotecas públicas con financiación municipal danesas y estableciendo bibliotecas en red o portales temáticos supervisados por el personal de las bibliotecas. El proceso de cooperación, la distribución y el uso de los productos han sido posibles por la presencia de una infraestructura en Internet muy bien desarrollada. Un componente clave para la promoción de la lectura es el portal en Internet litteratursiden.dk (portal danés sobre literatura), que permite que los autores conozcan a los lectores mediante la web y promueve actos en el espacio físico de la biblioteca, como por ejemplo Conoce el autor, presentaciones, debates y cafés literarios. Al facilitar y hacer más atractivo el acceso a los libros físicos a partir de actividades de autoservicio en Internet integradas al lugar web de la biblioteca —por ejemplo, préstamos y reservas, servicios de recomendación personalizados, clasificaciones y etiquetado al CIAP—, han aumentado de una manera considerable las oportunidades de lectura para los usuarios. En este artículo describimos experiencias para hacer más atractiva la selección del material de lectura a partir de presentaciones de libros en la red y de portales en los teléfonos móviles, y las posibilidades de crear grupos de lectura para los usuarios a través de Internet. También mencionamos el potencial de adoptar la ideología de la Web 2.0 y las prácticas de promoción de igual a igual y de creación de contenido; finalmente, tratamos brevemente la posibilidad de unir la web y el espacio físico de la biblioteca creando marcas o universos que podrían constituir un entorno para inculcar los valores de la lectura y de la literatura en diferentes públicos.
Visibilitat en el web dels centres de recursos per a l'aprenentatge i la investigació (CRAI) a les biblioteques universitàries
Authors: Herrera Morillas José Luis
Published: April 2022

Objectiu: Analitzar la visibilitat a la web del grau d'implantació del model de CRAI en biblioteques universitàries.
 Metodologia: Es du a terme una anàlisi de contingut de seus web de 69 biblioteques universitàries espanyoles així com dels seus plans estratègics per tal d’extreure la informació relacionada amb els objectius de la recerca. S’han pogut analitzar totes les seus web però només s’ha pogut accedir a 28 plans estratègics.
 Resultats: Es mostra, amb dades qualitatives i quantitatives, que, malgrat que no totes les biblioteques es troben en el mateix nivell de desenvolupament, la majoria ha assumit el repte d'adaptar-se a l'espai europeu d'educació superior, de manera que s’ha donat més protagonisme i més suport al procés d'aprenentatge. El model de CRAI, per tant, es fa visible en les seus web i els plans estratègics de la majoria de les biblioteques universitàries espanyoles.

Com enllacen les entitats no lucratives catalanes a Internet? Motivacions d'enllaços web en comunitats no acadèmiques
Authors: Sánchez Crujeiras David
Published: April 2022

Objectiu: Analitzar les motivacions dels enllaços web en entitats no lucratives catalanes per tal de determinar la influència de certs factors sobre els comportaments d'enllaç i així millorar la comprensió de la xarxa col·laborativa particular.
 Metodologia: S’utilitzen tècniques estadístiques sobre els enllaços web així com tècniques d'anàlisi de xarxes d'enllaços (AXE) a una mostra de 34 entitats no lucratives catalanes d'àmbit català. El programari emprat per a l'extracció d'enllaços ha estat SocSciBot. També ens hem basat també en els programes Excel, per al càlcul i l'obtenció de percentatges, i Pajek, com a eina de suport en la visualització de la xarxa obtinguda dels enllaços entre les seus de la mostra.
 Resultats: Tot i que cal recordar l'abast limitat d'aquest estudi, s'ha pogut corroborar que l'afiliació temàtica és un dels factors determinants per entendre els comportaments d'enllaços dins d'aquest àmbit; també s’ha observat com les entitats cíviques exhibeixen una major tendència a relacionar-se amb el sector associatiu de base i de caràcter més local. Quant a l'estructura social de la xarxa obtinguda a partir de la mostra, no sembla erroni determinar una certa importància de la semblança temàtica com a clau a les xarxes d'enllaços sorgides.
Un tournant entre deux vagues ? : les archives du féminisme en France et en Espagne depuis les années 1990
Authors: Jornet i Benito Núria , Grailles Bénédicte
Published: April 2022

Objectifs : Nous partons de l'hypothèse que nous sommes à un moment particulier de l'histoire des mémoires des féminismes, à un 'tournant archivistique' pour reprendre en la détournant l'expression de Kate Eichhorn. Nos objectifs sont de redéfinir les caractéristiques de ce tournant archivistique à l'aune d'exemples de centres ou de projets de centres de ressources documentaires et archivistiques en Espagne et en France dans les années 1990–2000, de les contextualiser par rapport à l'évolution des concepts et pratiques archivistiques, et de nous interroger sur un double mouvement paradoxal entre institutionnalisation et activisme communautaire.
 Méthodologie : Pour servir notre hypothèse de départ, nous avons procédé à l'élaboration d'une revue bibliographique motivée par une approche volontairement interdisciplinaire : études féministes et de genre, archivistique, French Theory, études culturelles. Nous nous sommes appuyées sur des études de cas en Espagne et en France afin d'élaborer des comparaisons pertinentes.
 Résultats : Le premier constat est celui d'une continuité entre seconde et troisième vagues féministes sur la question des archives. Le second est celui d'un tournant archivistique, mais avec des caractéristiques originales : entre réactivation et intensification, entre institutionnalisation et autonomie, ces militantismes archivistiques féministes concernent le féminisme majoritaire comme les féminismes minoritaires. La mise en archives appartient plus que jamais au répertoire d'actions féministe. Le troisième constat est celui de l'existence de communautés fortement adossées à des initiatives archivistiques féministes.

El currículo del grado en derecho, los valores fundamentales del ordenamiento jurídico y la educación jurídica clínica: una reformulación de prospectiva
Authors: Gascón Cuenca Andrés
Published: April 2022

En el presente texto se realiza una revisión crítica de la implementación del plan Bolonia en el estudio del Derecho y de cómo este supuso la mercantilización del currículum mediante la influencia de intereses privados en la determinación de los conocimientos y las habilidades a implementar. Esta tarea, que se realizó en detrimento del valor de la educación y del conocimiento como bienes comunes y estructurales en el desarrollo de la personalidad, implicó la incorporación de teorías como la del Capital Humano en la creación de los nuevos recorridos académicos, marginando asignaturas relativas a derechos humanos, filosofía o teoría del derecho, derecho antidiscriminatorio, deontología jurídica, entre muchas otras, que poco tienen que ver con este proceso y con los valores neoliberales promovidos por la globalización. Frente a esta realidad, que supone un peligro para el propio Estado social y democrático de Derecho, se propone la incorporación del modelo clínico jurídico para recuperar conocimientos fundamentales que el plan Bolonia aparcó, y que se estiman básicos en la formación de los futuros operadores jurídicos.
Interventions for Transition-Age Youth With Disabilities: A Meta-Analysis of Group Design Studies
Authors: Crowley Shannon
Published: April 2022

This meta-analytic review investigated interventions for transition-age youth diagnosed with autism, intellectual disability, or extensive support needs. Nineteen group design studies with 215 effect sizes met inclusion criteria. A robust variance estimation procedure that accounts for the clustering effect sizes within studies was used to synthesize effect sizes within each intervention and outcome type. Occupational Therapy/Physical Therapy interventions have significant and positive effects on gross motor outcomes (g = 0.73, p < 0.01). All remaining interventions and outcomes could not be synthesized due to a limited number of studies, but are further described in a narrative manner. Recommendations for future research include improving the methodological quality of intervention studies and further analyzing the effects of interventions for transition-age youth.
Hardware analysis for motion estimation task
Authors: Cohen Khen , Hodeda Gal , Almog Emmanuel , Raviv Dan , Mendlovic David
Published: April 2022

This work introduces hardware metrics to evaluate imaging sensor (camera) ability to cope with temporal change (motion). Shifting from images towards moving elements demands better tools for evaluation than just refresh rate, and this work is here to close that gap. We focus on the sampling frequency, signal to noise ratio, rolling shutter, and modulation transfer function as a set of parameters to define four fundamental conditions to evaluate and compare the quality of motion sensing. We further examine our theory on existing hardware used in modern equipment and report our findings.
Information gains from commercial spectral filters in anomalous trichromacy
Authors: Nascimento Sérgio M. C. , Foster David H.
Published: April 2022

Red-green color discrimination is compromised in anomalous trichromacy, the most common inherited color vision deficiency. This computational analysis tested whether three commercial optical filters with medium-to-long-wavelength stop bands increased information about colored surfaces. The surfaces were sampled from 50 hyperspectral images of outdoor scenes. At best, potential gains in the effective number of surfaces discriminable solely by color reached 9% in protanomaly and 15% in deuteranomaly, much less than with normal trichromacy. Gains were still less with lower scene illumination and more severe color vision deficiency. Stop-band filters may offer little improvement in objective real-world color discrimination.
Motion control for laser machining via reinforcement learning
Authors: Xie Yunhui , Praeger Matthew , Grant-Jacob James A. , Eason Robert W. , Mills Ben
Published: April 2022

Laser processing techniques such as laser machining, marking, cutting, welding, polishing and sintering have become important tools in modern manufacturing. A key step in these processes is to take the intended design and convert it into coordinates or toolpaths that are useable by the motion control hardware and result in efficient processing with a sufficiently high quality of finish. Toolpath design can require considerable amounts of skilled manual labor even when assisted by proprietary software. In addition, blind execution of predetermined toolpaths is unforgiving, in the sense that there is no compensation for machining errors that may compromise the quality of the final product. In this work, a novel laser machining approach is demonstrated, utilizing reinforcement learning (RL) to control and supervise the laser machining process. This autonomous RL-controlled system can laser machine arbitrary pre-defined patterns whilst simultaneously detecting and compensating for incorrectly executed actions, in real time.
Detailed balance analysis of vertical GaAs nanowire array solar cells: exceeding the Shockley Queisser limit
Authors: Haghanifar Sajad , Leu Paul W.
Published: April 2022

We performed detailed balance analysis using rigorous coupled-wave analysis (RCWA) on vertical GaAs nanowire (NW) arrays. Both freestanding NW arrays as well as NW arrays on a perfect back reflector are assessed. Both types of vertical NW arrays demonstrate efficiencies that exceed the Shockley Queisser (SQ) or radiative efficiency limit when the NWs are sufficiently long. The use of a back reflector enhances the efficiency of NW solar cells by increasing solar absorption and suppressing emission from the backside of the solar cell. We study the light trapping and material reduction advantages of NWs. Furthermore, we compare simulations that evaluate detailed balance efficiency with ultimate efficiency and show that ultimate efficiency studies can determine near-optimal solar cells while vastly reducing the number of simulations that need to be performed. While open circuit voltages above the radiative limit can be achieved, tradeoffs with short circuit current must be carefully considered. We also compare our simulation results to other claims in the literature that NWs are capable of exceeding the SQ limit.
Secure and noise-resistant underwater wireless optical communication based on spectrum spread and encrypted OFDM modulation
Authors: Zhang Jialiang , Gao Guanjun , Zhang Jie , Guo Yonggang
Published: April 2022

In addition to requirements on increasing transmission distance and bitrate, the study of underwater wireless optical communication (UWOC) is also facing limitations and challenges, such as interference induced by background noise, demand of higher receiver sensitivity, and communication security issues. In this paper, we experimentally demonstrate a physical layer secure and noise-resistant UWOC system based on spectrum spread and encrypted orthogonal frequency division multiplexing (SSE-OFDM) modulation, transmission through a 14.2 m sediment circulating water tank. Firstly, experimental results show that the required optical power ratio of signal and noise light (OPR) for QPSK signal under BER threshold of 3.8×10−3 is around −5.77 dB for a spectrum spread factor (N) of 100, with a signal-to-noise ratio (SNR) improvement of 19.06 dB. Secondly, without the background noise interference, the receiver sensitivity is also improved from −50 dBm to −62.4 dBm by using the SSE-OFDM modulation, achieving a maximum attenuation length (AL) of 19.67. Thirdly, physical layer security of UWOC can also be realized, which suppresses the SNR of eavesdropper to −3.72 dB while improving SNR of the authorized receiver to 17.56 dB under the condition of no leakage of keys. Additionally, analytical expressions for SSE-OFDM based UWOC performance are also derived, which agree well with the experimental results. Based on the analytical expressions, the maximum secrecy capacity Cs for SSE-OFDM based UWOC system under eavesdropping can be obtained by optimizing the intentionally inserted artificial noise power ratio and the spectrum spread factor N.

In this study, an analytical formula for the self-focusing length of a radially polarized beam (RPB) is first derived, which has a similar behavior to the semi-empirical Marburger formula of a Gaussian beam, and is beneficial to quantitatively and qualitatively analyze practical experimental scenarios. However, the relation of the self-focusing length with the states of polarization (SoPs) was evaluated, and it was found that RPB with spatially inhomogeneous SoP at the field cross-section can retain a further self-focusing length compared to a beam with a spatially homogeneous one. The influence of the topological charge on the self-focusing length is explored, which shows that RPB with a low topological charge can achieve a high-power density at a relatively further receiver plane. Therefore, it is demonstrated that the RPB as a laser source not only extends the self-focusing length, but also improves the power density of the target. With the help of RPB, it is possible to realize a controllable self-focusing length and a high target optical power density, which may have potential applications in fine optical manipulation, optical communication, high-power long-range laser atmospheric propagation, and related areas.

A micro ultrasonic sensor based on an advanced suspended-core fiber is proposed and employed for in-lab seismic physical modeling. A free suspended core is obtained by acid corrosion and two cascaded uniform fiber Bragg gratings (FBGs) are imprinted in the suspended-core fiber. The sensor response and stability are largely improved due to the using of dual-FBG reflectors instead of weak-reflection fiber mirrors for constructing an in-fiber interferometer. The characteristics of reflection spectra and ultrasonic response of the sensor are analyzed and demonstrated experimentally. Comparative measurements are also carried out to prove the sensor superiority over the conventional weak-reflection one. Moreover, the sensor is used for seismic physical modeling to show its ability of practicable usage. Both the crosswell seismic and surface seismic in seismic exploration are modeled respectively based on reservoir and fault models. Various reservoir velocities are measured and each is consistent with the reported results. The fault features are also well reconstructed in the form of a cross-section model image. The improved sensor approach greatly promotes the application of the suspended-core fiber for weak acoustic detection in seismic physical modeling.

The very long wavelength infrared (VLWIR, >14 µm) spectral band is an indispensable part of new-generation infrared remote sensing. Mercury cadmium telluride (HgCdTe or MCT) has shown excellent potential across the entire infrared band. However, the dark current, which is extremely sensitive to the technological level and small Cd composition, severely limits the performance of VLWIR HgCdTe photodiodes. In this study, cut-off wavelengths of up to 15 µm for HgCdTe devices with novel P-G-I (including wide bandgap p-type cap layer, grading layer and intrinsic absorption layer) designs have been reported. Compared with a device with a double-layer heterojunction (DLHJ) structure, the designed P-G-I structure successfully reduced dark current by suppressing the Shockley–Read–Hall process. Considering the balance of quantum efficiency and dark current, with the introduction of an approximately 0.8 µm thickness Cd composition grading layer, the device can achieve a high detectivity of up to 2.5×1011 cm Hz1/2 W−1. Experiments show that the P-G-I-T device has a lower dark current and a better SRH process suppressing ability than DLHJ devices, the measured detectivity achieved 8.7×1010 cm Hz1/2 W−1. According to additional research, the trap-assisted tunneling current is the primary component of the dark current. Controlling the trap concentration to as low as 1×1013 cm−3 will be continuous and meaningful work. The proposed study provides guidance for VLWIR HgCdTe photodetectors.

Monolithic integrated receivers are highly desired due to the potential of mass production and the reduction of device size and cost. In this Letter, a monolithic integrated optical wireless communication (OWC) receiver with optical preamplifiers is designed, fabricated, and investigated to achieve high sensitivity based on photonic integration technology. The proposed receiver consists of one waveguide PIN photodetector integrated with two semiconductor optical amplifiers (SOAs). Compared with using a one-stage optical amplifier, using two independent SOAs as a two-stage amplifier offers the advantage of optimizing the noise figure of each amplifier independently by tuning their injection currents, which leads to the reduction of the total noise and an improvement of the receiver sensitivity. The achieved sensitivity for a 10-Gb/s OOK signal with 10-dBm launch power at 1550-nm wavelength by using the designed receiver is up to −27.5 dBm at a bit-error-ratio (BER) level of 3.1×10−3 over a 0.9-m indoor free-space link. The experimental results show the potential to achieve a high-speed OWC link with high sensitivity by using a cascaded SOA/PIN monolithic integrated receiver.

The engineering of exceptional points (EPs) in open optical systems has lately attracted much attention for developing future all-optical devices. However, investigation of the fascinating features of EPs in fiber geometries is lacking. We design a fabrication feasible dual-core optical fiber segment, where non-Hermiticity in terms of a symmetric customized gain–loss profile is introduced to modulate the interaction between two corresponding coupled modes toward hosting a dynamical EP encirclement scheme in the gain–loss parameter space. An asymmetric conversion process between two supported modes is reported by exploiting the chirality of the encountered EP. The proposed scheme can lead to an advanced platform to design mode-manipulative all-optical components in communication and all-fiber photonic devices.

Indoor residual spraying of insecticides (IRS) is a key malaria vector control strategy. Whilst human attitude towards IRS is monitored before or shortly after implementation, human activities leading to the modification of insecticide-treated walls post-IRS are not. This could inadvertently reduce the protective effects of IRS. We monitored the extent of modifications to the sprayed indoor wall surfaces by household owners for six months post-IRS campaigns in two districts targeted for malaria elimination in southern Mozambique. In parallel, we assessed building of any additional rooms onto compounds, and mosquito net use. We quantified the contribution of wall modifications, added rooms, prolonged spray campaigns, and product residual efficacies on actual IRS coverage and relative mosquito bite reduction, using a mechanistic approach. Household owners continually modified insecticide-treated walls and added rooms onto compounds. Household surveys in southern Mozambique showed frequent modification of indoor walls (0–17.2% of households modified rooms monthly) and/or added rooms (0–16.2% of households added rooms monthly). Actual IRS coverage reduced from an assumed 97% to just 39% in Matutuine, but only from 96% to 91% in Boane, translating to 43% and 5.8% estimated increases in relative daily mosquito bites per person. Integrating post-IRS knowledge, attitude, and practice (KAP) surveys into programmatic evaluations to capture these modification and construction trends can help improve IRS program efficiency and product assessment.

Background

Animal African Trypanosomiasis (AAT) is one of the most economically important diseases affecting livestock productivity in sub-Saharan Africa. The disease is caused by a broad range of Trypanosoma spp., infecting both wild and domesticated animals through cyclical and mechanical transmission. This study aimed to characterize trypanosomes present in cattle at regular intervals over two years in an AAT endemic and a non-endemic region of Ghana.

Methodology/Principal findings

Groups of cattle at Accra and Adidome were selected based on their geographical location, tsetse fly density, prevalence of trypanosomiasis and the breed of cattle available. Blood for DNA extraction was collected at approximately four to five-week intervals over a two-year period. Trypanosome DNA were detected by a sensitive nested PCR targeting the tubulin gene array and massively parallel sequencing of barcoded amplicons. Analysis of the data was a semi-quantitative estimation of infection levels using read counts obtained from the sequencing as a proxy for infection levels. Majority of the cattle were infected with multiple species most of the time [190/259 (73%) at Adidome and 191/324 (59%) at Accra], with T. vivax being the most abundant. The level of infection and in particular T. vivax, was higher in Adidome, the location with a high density of tsetse flies. The infection level varied over the time course, the timings of this variation were not consistent and in Adidome it appeared to be independent of prophylactic treatment for trypanosome infection. Effect of gender or breed on infection levels was insignificant.

Conclusions/Significance

Most cattle were infected with low levels of several trypanosome species at both study sites, with T. vivax being the most abundant. The measurements of infection over time provided insight to the importance of the approach in identifying cattle that could suppress trypanosome infection over an extended time and may serve as reservoir.
