Extra-Mediterranean glacial refugia in a Mediterranean faunal element: the phylogeography of the chalk-hill blue Polyommatus coridon (Lepidoptera, Lycaenidae)
Authors: Kühne Gero , Kosuch Joachim , Hochkirch Axel , Schmitt Thomas
Published: January 2018

Most warm-adapted Central European species are thought to have survived ice ages exclusively in Mediterranean refugia. During recent years, this point of view has been questioned. Therefore, we tested the hypothesis that extra-Mediterranean refugia also played a role in warm-adapted insect species and selected the chalk-hill blue,Polyommatus coridon. We sequenced two mitochondrial loci (COI, CR) in 150 individuals from 30 populations covering nearly the complete range. Minimum spanning networks and other statistical analyses concordantly revealed four genetic lineages with strong phylogeographic signal: a western group in Italy, France and western/central Germany, an eastern lineage in the Balkan Peninsula, the Carpathian Basin and eastern Central Europe, an Alpine group with populations in the Alps and southern Germany and a Pyrenean group. Our results are generally consistent with previous analyses forP. coridonbased on allozymes and DNA sequences, but provide additional insights. We propose that these four lineages have evolved during allopatry in different glacial refugia, two in typical Mediterranean refugia (Apennines and Balkan Peninsulas), but two in extra-Mediterranean areas south of the Alps and Pyrenees. This supports survival of warm-adapted organisms in these regions in close geographic proximity to the refugia of high mountain species.

Self-Stigma and Age-Related Hearing Loss: A Qualitative Study of Stigma Formation and Dimensions
Authors: David Dana , Zoizner Gil , Werner Perla
Published: January 2018

Purpose

This study explored experiences of self-stigma among older persons with age-related hearing loss (ARHL) using Corrigan's conceptualization of self-stigma process formation and the attribution model as its theoretical framework.

Method

In-depth semistructured interviews were conducted with 11 older persons (mean age = 81 years) with ARHL.

Results

Self-stigma was present in the lives of the participants. Analysis revealed the existence of 3 stages of self-stigma in which the 3 core dimensions of stigma (cognitive attributions: being old, stupid, and crippled; emotional reactions: shame, pity, and feeling ridiculed; and behavioral reactions: concealment, distancing, and adapting to hearing aids) were observed. Hearing devices emerged as having a significant influence on stigmatic experiences in all stages and dimensions of self-stigma.

Conclusion

The study contributes to the theoretical and practical understanding of self-stigma regarding ARHL as well as to the understanding of the role of hearing devices in the development of this stigma.
Single‐sensor based indoor localisation by exploiting multipath propagation
Authors: Hu Bin , Shi Zhenyu , Wang Yi
Published: January 2018

An effective and reliable indoor positioning is a highly needed service. A bi‐iterative algorithm for mobile user localisation in an indoor space is presented based on the multipath measurements exploited by a single sensor. The bi‐iterative algorithm calculates the locations of the mobile user and the so‐called virtual sensors, which are mirror images of the physical sensors, alternatively. Notably, this algorithm does not require any a priori knowledge about the environment. Simulation results show that the location of virtual sensors can be accurately estimated after a couple of iterations, and in return, they enhance the accuracy of user localisation. The proposed algorithm can localise a user with sub‐metre accuracy in most cases. Moreover, it even outperforms the positioning algorithms that require full information about the environment.
Low‐complexity, high‐speed multi‐size cyclic‐shifter for quasi‐cyclic LDPC decoder
Authors: Kang H.‐J. , Yang B.‐D.
Published: January 2018

Quasi‐cyclic low‐density parity check (QC‐LDPC) codes are being widely used in communication standards, and the decoder of QC‐LDPC codes requires a unique type of rotator. The unique rotator, called a multi‐size cyclic‐shifter (MSCS), should be able to rotate data with various sizes, and many structures have been proposed for the operation. A low‐complexity, high‐speed MSCS structure is proposed, in which a part of the previous smallest structure is replaced with a structure with less delay and comparable area. The synthesis results present that the proposed structure achieves not only the highest speed but also the lowest complexity after synthesis.
Nano‐rectenna powered body‐centric nano‐networks in the terahertz band
Authors: Rong Zhichao , Leeson Mark S. , Higgins Matthew D. , Lu Yi
Published: January 2018

A wireless body‐centric nano‐network consists of various nano‐sized sensors with the purpose of healthcare application. One of the main challenges in the network is caused by the very limited power that can be stored in nano‐batteries in comparison with the power required to drive the device for communications. Recently, novel rectifying antennas (rectennas) based on carbon nanotubes (CNTs), metal and graphene have been proposed. At the same time, research on simultaneous wireless information and power transfer (SWIPT) schemes has progressed apace. Body‐centric nano‐networks can overcome their energy bottleneck using these mechanisms. In this Letter, a nano‐rectenna energy harvesting model is developed. The energy harvesting is realised by a nano‐antenna and an ultra‐high‐speed rectifying diode combined as a nano‐rectenna. This device can be used to power nanosensors using part of the terahertz (THz) information signal without any other system external energy source. The broadband properties of nano‐rectennas enable them to generate direct current (DC) electricity from inputs with THz to optical frequencies. The authors calculate the output power generated by the nano‐rectenna and compare this with the power required for nanosensors to communicate in the THz band. The calculation and analysis suggest that the nano‐rectenna can be a viable approach to provide power for nanosensors in body‐centric nano‐networks.

Optimal placement of switches can play a key role in providing resilience to power distribution systems against major faults caused by natural disasters. This study presents a resilience‐based framework for optimal switch placement in distribution systems being consistent with the expansion plans of distributed generation units. At first, the impact of hurricanes on distribution system components is modelled using the geographic information system of distribution grid and the strength of components against extreme weather‐related events. Then, a new resiliency index is proposed to assess the resilience of distribution grids. This index is involved in a mathematical model of the switch placement problem and the obtained formulation is modelled as a mixed integer linear programming optimisation problem. The presented framework is implemented on two test systems, i.e. an illustrative test system and Bus 4 of the Roy Billinton test system. The results prove the effectiveness of this approach to improving the resiliency of distribution systems.

Hysteretic comparators are often used to implement sliding‐mode controllers or other type of discontinuous regulators for power switching converters. Their design is usually performed analogically yielding robust and fast controllers that can even allow converter operation with high values of duty cycle. A new analogue implementation based on a low‐cost microcontroller is described in this study showing the mentioned advantages plus the flexibility of a programmable digital system. The proposed comparator employs some microcontroller peripherals without consuming execution time of the control algorithm and without requiring interruption management. It provides variable hysteresis width to obtain constant switching frequency in sliding‐mode strategies and can be used in any type of hard switching converter. The dynamic performance of the method is verified experimentally in a boost converter‐based rectifier with power factor correction and output voltage regulation in one single stage. The boost converter operates in sliding mode with constant switching frequency and results in a total harmonic distortion of the input current <1%.

Context. From stars to active galactic nuclei, many astrophysical systems are surrounded by an equatorial distribution of dusty material that is, in a number of cases, spatially unresolved even with cutting edge facilities.

Aims. In this paper, we investigate if and how one can determine the unresolved and heterogeneous morphology of dust distribution around a central bright source using time-resolved polarimetric observations.

Methods. We used polarized radiative transfer simulations to study a sample of circumnuclear dusty morphologies. We explored a grid of geometrically variable models that are uniform, fragmented, and density stratified in the near-infrared, optical, and ultraviolet bands, and we present their distinctive time-dependent polarimetric signatures.

Results. As expected, varying the structure of the obscuring equatorial disk has a deep impact on the inclination-dependent flux, polarization degree and angle, and time lags we observe. We find that stratified media are distinguishable by time-resolved polarimetric observations, and that the expected polarization is much higher in the infrared band than in the ultraviolet. However, because of the physical scales imposed by dust sublimation, the average time lags of months to years between the total and polarized fluxes are important; these time lags lengthens the observational campaigns necessary to break more sophisticated, and therefore also more degenerated, models. In the ultraviolet band, time lags are slightly shorter than in the infrared or optical bands, and, coupled to lower diluting starlight fluxes, time-resolved polarimetry in the UV appears more promising for future campaigns.

Conclusions. Equatorial dusty disks differ in terms of inclination-dependent photometric, polarimetric, and timing observables, but only the coupling of these different markers can lead to inclination-independent constraints on the unresolved structures. Even though it is complex and time consuming, polarized reverberation mapping in the ultraviolet-blue band is probably the best technique to rely on in this field.

Color management of integrated photovoltaics must meet two criteria of performance: provide maximum conversion efficiency and allow getting the chosen colors with an appropriate brightness, more particularly when using side by side solar cells of different colors. As the cooling conditions are not necessarily optimal, we need to take into account the influence of the heat transfer and temperature. In this article, we focus on the color space and brightness achieved by varying the antireflective properties of flat silicon solar cells. We demonstrate that taking into account the thermal effects allows freely choosing the color and adapting the brightness with a small impact on the conversion efficiency, except for dark blue solar cells. This behavior is especially true when heat exchange by convection is low. Our optical simulations show that the perceived color, for single layer ARC, is not varying with the position of the observer, whatever the chosen color. The use of a double layer ARC adds flexibility to tune the wanted color since the color space is greatly increased in the green and yellow directions. Last, choosing the accurate material allows both bright colors and high conversion efficiency at the same time.

As a certified professional, teacher forms indispensable roles in achieving the learning objectives. The complexity of teacher’s profession decidedly requires the teacher to master a number of competencies and skills. One of them is to master the basic teaching skills. Realizing the complexities of the teacher’s profession and the requirement of teacher’s profession, LPTK –Faculty of Teacher Training and Education– which produces professional teacher, requires enhancing the teacher’s quality and creativity through pre-service teaching and training. Microteaching is one of the efforts to prepare the candidate for a professional teacher in higher education. The growth of a number of students being served with the availability of micro teaching laboratories is, however, disproportionate. Consequently, the problems faced are the time management, the laboratory utilization, the availability of sufficient microteaching infrastructures as well as the implementation of micro teaching itself. One of the ways to solve the problems is to develop a microteaching model adapting the force driving sophisticated ICT named TADALURING Microteaching Learning Model (TMLM). The Instructional Systems Design (ISD) made use of developing the model is Borg and Gall procedures. The cyclical phases of conducting the research were preliminary research, development, field-testing, and dissemination. The research finding indicates that the trial-tested model is stated valid, practical, and effective. The TADALURING Microteaching Learning Model (TMLM) is essentially accentuated on a face-to-face classroom, online and offline practices.

The change of Indonesia’s national curriculum from School-Based Curriculum 2006 (hereafter SBC 2006) to Curriculum 2013 (hereafter CR 2013) has caused modifications in the assessment system which requires teachers to use authentic assessment. Many teachers are facing setbacks in the implementation of this assessment, particularly in the attitude aspect. This qualitative research mainly focused on investigating the problems in conducting the attitude assessment faced by teachers in CR 2013. Three English teachers from three junior high schools in Banda Aceh were selected and interviewed with questions adapted from Handayani (2014) and Eliza (2015). The document analysis of attitude assessment was also done to see the reports of students’ attitudes. The findings showed that the teachers knew the importance of authentic assessment as a necessity for assessing students’ learning outcomes in CR 2013, but they admitted that it was complicated since many categories need to be assessed in detail. They find it impossible to assess all of the students in every school day. When parents do not want to cooperate if their children are in need of attention from both parents and teachers, it is also an obstacle for the teachers to do the assessments. Furthermore, the teachers deemed that self- and peer-assessment were ineffective and the paper further discusses why it is so.

As an EFL country, English Language Teaching (ELT) in Indonesia should be more focused on developing students’ strategy, particularly communication strategy (CS). The reason is because these students are triggered by instrumental motivation in learning English. However, awareness toward CS should also be possessed by teachers so they can develop students’ CS through certain way. Unfortunately, it is rarely found English teacher who is aware about this notion. Thus, this study was conducted to provide data about initial CS of adult students in private university in Bali. According to experts, this age level has already got fully developed cognitive and linguistic capabilities. Thus, they are considered to be able to employ and use CS well. Through this study it is found that they possess 20 initial CSs out of 38 CSs from the referred taxonomy. The findings of this study could be beneficial for the development and novelty of future research concerning with CS and to enhance teachers’ awareness toward CS, particularly the ones who establish private course offering intensive speaking program as well as for the lecturers in the concerned university.
