Co-creating narratives for WEF nexus governance: a Quantitative Story-Telling case study in the Canary Islands
Authors: Cabello Violeta , Romero David , Musicki Ana , Guimarães Pereira Ângela , Peñate Baltasar 
Published: March 2021

AbstractThe literature on the water–energy–food nexus has repeatedly signaled the need for transdisciplinary approaches capable of weaving the plurality of knowledge bodies involved in the governance of different resources. To fill this gap, Quantitative Story-Telling (QST) has been proposed as a science for adaptive governance approach that aims at fostering pluralistic and reflexive research processes to overcome narrow framings of water, energy, and food policies as independent domains. Yet, there are few practical applications of QST and most run on a pan-European scale. In this paper, we apply the theory of QST through a practical case study regarding non-conventional water sources as an innovation for water and agricultural governance in the Canary Islands. We present the methods mixed to mobilize different types of knowledge and analyze interconnections between water, energy, and food supply. First, we map and interview relevant knowledge holders to elicit narratives about the current and future roles of alternative water resources in the arid Canarian context. Second, we run a quantitative diagnosis of nexus interconnections related to the use of these resources for irrigation. This analysis provides feedback to the narratives in terms of constraints and uncertainties that might hamper the expectations posed on this innovation. Thirdly, the mixed analysis is used as fuel for discussion in participatory narrative assessment workshops. Our experimental QST process succeeded in co-creating new knowledge regarding the water–energy–food nexus while addressing some relational and epistemological uncertainties in the development of alternative water resources. Yet, the extent to which mainstream socio-technical imaginaries surrounding this innovation were transformed was rather limited. We conclude that the potential of QST within sustainability place-based research resides on its capacity to: (a) bridge different sources of knowledge, including local knowledge; (b) combine both qualitative and quantitative information regarding the sustainable use of local resources, and (c) co-create narratives on desirable and viable socio-technical pathways. Open questions remain as to how to effectively mobilize radically diverse knowledge systems in complex analytical exercises where everyone feels safe to participate.
Sustainable transitions towards a resilient and decentralised future: Japan’s Circulating and Ecological Sphere (CES)

Published: March 2021

AbstractGlobal environmental change, the depletion of natural resources, and unacceptable levels of pollution, among other anthropogenic impacts on the planet and its ecosystems, demand a radical shift in the way humankind develops. Global agreements like the “2030 Agenda for Sustainable Development” or the “Paris Agreement on Climate Change” seek to promote sustainable development and its integration in policymaking. Against this backdrop, the Government of Japan in its Fifth Basic Environment Plan of 2018 proposed the concept of the Circulating and Ecological Sphere (CES) to guide sustainable transitions in light of the sustainable development goals (SDGs). The CES provides a framework for a new paradigm in sustainable development bringing together existing approaches, namely, rural–urban linkages, ecosystem-based solutions, decarbonisation, and resource circulation. Still in an embryonic stage, some regional and local authorities in Japan have started to experiment with ways to apply this concept on the ground. Drawing on a systematic literature review on the different components covered by the CES, along with analysis of a case study in Suzu, Japan, this paper explores how this new concept can contribute to achieve a sustainable future.
High performance peel grinding of steel shafts using coarse electroplated CBN grinding wheels
Authors: Denkena B. , Krödel A. , Wilckens M. 
Published: March 2021

AbstractGrinding is widely known for its low material removal rates and high surface quality. However, recent developments in production processes for cubic boron nitride (CBN) abrasive grains have led to commercially available grain sizes larger than 300 µm. These superabrasive CBN-grains allow higher material removal rates during grinding of hardened steel components. Currently, these components are pre-machined with turning processes before hardening and finishing the work piece by grinding. However, the turning process can be eliminated by grinding with coarse CBN-grains since higher depths of cut are achievable when machining hardened components. This paper explores the limits of grinding wheels using grains with a size of B602 during soft and hard machining in comparison to conventional B252 grains. It is shown that the use of coarser grains leads to lower process forces, higher (tensile) residual stress and higher surface roughness. Residual stress and surface roughness are of less importance as these grains are to be used mainly in roughing operations with ensuing finishing operations for the required surface properties. Over all investigations, especially in hard machining, neither grain nor tool wear was observed for the B602 grains, whereas the B252 tool was severely clogged during the experiments. Additionally, the grinding force ratio indicates that the coarse grain tools have not yet reached their productivity limit as it increases over all investigated feeds. This indicates improving tool performance with lower amounts of rubbing for increasing feed rate during hard grinding and shows the potential for the industrial use of higher feed rates with larger grains.

AbstractIn deep neural network compression, channel/filter pruning is widely used for compressing the pre-trained network by judging the redundant channels/filters. In this paper, we propose a two-step filter pruning method to judge the redundant channels/filters layer by layer. The first step is to design a filter selection scheme based on $$\ell _{2,1}$$

-norm by reconstructing the feature map of current layer. More specifically, the filter selection scheme aims to solve a joint $$\ell _{2,1}$$

-norm regularization plays a role in the channel/filter selection, while the $$\ell _{2,1}$$

-norm feature map reconstruction error term plays a role in the robust reconstruction. In this way, the proposed filter selection scheme can learn a column-sparse coefficient representation matrix that can indicate the redundancy of filters. Since pruning the redundant filters in current layer might dramatically influence the output feature map of the following layer, the second step needs to update the filters of the following layer to assure output of feature map approximates to that of baseline. Experimental results demonstrate the effectiveness of this proposed method. For example, our pruned VGG-16 on ImageNet achieves $$4\times $$

Published: March 2021

AbstractKey requirements of successful animal behavior research in the laboratory are robustness, objectivity, and high throughput, which apply to both the recording and analysis of behavior. Many automatic methods of monitoring animal behavior meet these requirements. However, they usually depend on high-performing hardware and sophisticated software, which may be expensive. Here, we describe an automatic infrared behavior-monitor (AIBM) system based on an infrared touchscreen frame. Using this, animal positions can be recorded and used for further behavioral analysis by any PC supporting touch events. This system detects animal behavior in real time and gives closed-loop feedback using relatively low computing resources and simple algorithms. The AIBM system automatically records and analyzes multiple types of animal behavior in a highly efficient, unbiased, and low-cost manner.
Looking for the missing link in the evolution of black inks

Published: March 2021

AbstractIn the transition from carbon to iron-gall inks, the two documents from the Egyptian Museum and Papyrus Collection in Berlin with shelfmarks P 13500 and P 13501 discussed in this work present an important case. Their inks appear brownish, although they date back to the fourth and third century BCE, when carbon inks are believed to have been commonly if not exclusively used. Using imaging micro-X-ray fluorescence and infrared reflectography, we discovered that the inks in both documents contain a significant amount of copper in addition to carbon. Comparing the extant recipes for black writing inks and the experimental evidence, we suggest that these inks are a transition between the pure carbon and the iron-gall inks. Such inks may have been quite common before the production of iron-gall ink was clearly understood and established.
Cognitive Structuralism: Explaining the Regularity of the Natural Numbers Progression
Authors: Quinon Paula 
Published: March 2021

AbstractAccording to one of the most powerful paradigms explaining the meaning of the concept of natural number, natural numbers get a large part of their conceptual content from core cognitive abilities. Carey’s bootstrapping provides a model of the role of core cognition in the creation of mature mathematical concepts. In this paper, I conduct conceptual analyses of various theories within this paradigm, concluding that the theories based on the ability to subitize (i.e., to assess anexactquantity of the elements in a collection without counting them), or on the ability to approximate quantities (i.e., to assess anapproximatequantity of the elements in a collection without counting them), or both, fail to provide a conceptual basis for bootstrapping the concept of an exact natural number. In particular, I argue that none of the existing theories explains one of the key characteristics of the natural number structure: the equidistances between successive elements of the natural numbers progression. I suggest that this regularity could be based on another innate cognitive ability, namely sensitivity to the regularity of rhythm. In the final section, I propose a new position within the core cognition paradigm, inspired by structuralist positions in philosophy of mathematics.
Benefits of EPAs at risk? The influence of the workplace environment on the uptake of EPAs in EPA-based curricula
Authors: Van Loon Karsten Arthur , Bonnie Linda Helena Anna , Van Dijk Nynke , Scheele Fedde 
Published: March 2021

Introduction Entrustable Professional Activities (EPAs) have been applied differently in many postgraduate medical education (PGME) programmes, but the reasons for and the consequences of this variation are not well known. Our objective was to investigate how the uptake of EPAs is influenced by the workplace environment and to what extent the benefits of working with EPAs are at risk when the uptake of EPAs is influenced. This knowledge can be used by curriculum developers who intend to apply EPAs in their curricula.
Method For this qualitative study, we selected four PGME programmes: General Practice, Clinical Geriatrics, Obstetrics & Gynaecology, and Radiology & Nuclear Medicine. A document analysis was performed on the national training plans, supported by the AMEE Guide for developing EPA-based curricula and relevant EPA-based literature. Interviews were undertaken with medical specialists who had specific involvement in the development of the curricula. Content analysis was employed and illuminated the possible reasons for variation in the uptake of EPAs.
Results An important part of the variation in the uptake of EPAs can be explained by environmental factors, such as patient population, the role of the physician in the health-care system, and the setup of local medical care institutions where the training programme takes place. The variation in uptake of EPAs is specifically reflected in the number and breadth of the EPAs, and in the way the entrustment decision is executed within the PGME programme.
Combined Interventional Treatment of Refractory Chronic Migraine
Authors: Voloshin Alexey G. , Moiseeva Irina V. 
Published: March 2021

AbstractMigraine is one of the main causes of disability in modern world. Treatment of chronic refractory migraine (RCM) would be a challenge even for experienced physician. The aim of this study was to analyze the effect of combination therapy for RCM: greater occipital nerve’s (GON) pulsed radiofrequency (PRF) and botulinum toxin injections. We observed 6 female patients, suffering from RCM according to the European Headache Federation criteria. All patients had long history of migraine (5–44 years) with conservative treatment failure (at least three medication groups). Their migraine could be classified as refractory for long period of time (1–10 years). All of our patients passed a combination of PRF and BTA injection as consecutive 1-day treatments. Botulinum toxin type A injections were done in accordance to the PREEMPT protocol, followed by ultrasound-guided PRF of GONs bilateral. The observation period was 6 months after the procedure. We observed a positive response to treatment in all patients with dramatic reduction of pain intensity (from 7 ± 1 to 2 ± 2 on NRS scale) and significant decrease in the number of headache days (from 22 ± 5 to 4 ± 4) during first month after treatment. Two patients (30%) were pain free after the treatment until the end of the observation. No adverse effects were registered. Bilateral GON’s PRF followed by botulinum toxin therapy as 1-day treatment may be a useful option for the treatment of refractory chronic migraine. These interventional procedures are effective, minimally invasive, inexpensive, safe, and well-tolerated and can be performed on an outpatient basis.

Published: March 2021

AbstractAlthough advances in cancer treatment and early diagnosis have significantly improved cancer survival rates, cancer therapies can cause serious side effects, including ovarian failure and infertility, in women of reproductive age. Infertility following cancer treatment can have significant adverse effects on the quality of life. However, established methods for fertility preservation, including embryo or oocyte cryopreservation, are not always suitable for female cancer patients because of complicated individual conditions and treatment methods. Ovarian tissue cryopreservation and transplantation is a promising option for fertility preservation in pre-pubertal girls and adult patients with cancer who require immediate treatment, or who are not eligible to undergo ovarian stimulation. This review introduces various methods and strategies to improve ovarian tissue cryopreservation and transplantation outcomes, to help patients and clinicians choose the best option when considering the potential complexity of a patient’s situation. Effective multidisciplinary oncofertility strategies, involving the inclusion of a highly skilled and experienced oncofertility team that considers cryopreservation methods, thawing processes and devices, surgical procedures for transplantation, and advances in technologies, are necessary to provide high-quality care to a cancer patient.
Hearing from the ocean and into the river: the evolution of the inner ear of Platanistoidea (Cetacea: Odontoceti)

Published: March 2021

AbstractThe inner ear of the two higher clades of modern cetaceans (Neoceti) is highly adapted for hearing infrasonic (mysticetes) or ultrasonic (odontocetes) frequencies. Within odontocetes, Platanistoidea comprises a single extant riverine representative, Platanista gangetica, and a diversity of mainly extinct marine species from the late Oligocene onward. Recent studies drawing on features including the disparate tympanoperiotic have not yet provided a consensus phylogenetic hypothesis for platanistoids. Further, cochlear morphology and evolutionary patterns have never been reported. Here, we describe for the first time the inner ear morphology of late Oligocene–early Miocene extinct marine platanistoids and their evolutionary patterns. We initially hypothesized that extinct marine platanistoids lacked a specialized inner ear like P. gangetica and thus, their morphology and inferred hearing abilities were more similar to those of pelagic odontocetes. Our results reveal there is no “typical” platanistoid cochlear type, as the group displays a disparate range of cochlear anatomies, but all are consistent with high-frequency hearing. Stem odontocete Prosqualodon australis and platanistoid Otekaikea huata present a tympanal recess in their cochlea, of yet uncertain function in the hearing mechanism in cetaceans. The more basal morphology of Aondelphis talen indicates it had lower high-frequency hearing than other platanistoids. Finally, Platanista has the most derived cochlear morphology, adding to evidence that it is an outlier within the group and consistent with a >9-Myr-long separation from its sister genus Zarhachis. The evolution of a singular sound production morphology within Platanistidae may have facilitated the survival of Platanista to the present day.
Unicuspid and quadricuspid aortic valves: two case reports and literature review
Authors: Aslan Eyup 
Published: March 2021

AbstractThere are three cusps in a normally developed aortic valve. Abnormal excavation or fusion, during the embryological development of the aortic valve, results in a varying number of cusps. Bicuspid aortic valve is the most common, but more rarely, unicuspid and quadricuspid aortic valves can be seen.Here, a case of a 16-year-old male with a unicommissural unicuspid aortic valve and a case of a 13-year-old female with a quadricuspid aortic valve were reported.

Published: March 2021

AbstractA time-domain duplexing radio frequency (RF) front-end with integrated antenna switch, power amplifier (PA), and low noise amplifier (LNA) was developed aiming for fifth-generation communication (5G) applications covering 24–28 GHz frequency range. Antenna switch utilizes pre-existing LNA input matching network together embedded with grounded shunt transistor switch to provide sufficient isolation of receive side from PA. Respectively, high impedance of off-state PA is assumed to achieve acceptable receive performance. Resulting output power is 13.6 dBm with 15 dB of peak small-signal gain at 28 GHz. Maximum average channel power was 4.8 dBm with 100 MHz 64-QAM OFDM signal within 5G adjacent channel power ratio and error vector magnitude specifications. Receive (RX) front-end achieves 5 dB noise figure at 24 GHz and 7 dB of peak gain. Performances of amplifiers degraded only by 2 dB from switch integration. The front-end dissipates 183 and 4.6 mW of power in transmit and receive mode, respectively. The simplistic design method minimizes cost both in circuit area (only 0.19 mm2) and design time making this front-end an attractive alternative in massive phased array applications using 22 nm complementary metal oxide semiconductor (CMOS) fully depleted silicon on insulator process.
Role of testosterone: cortisol ratio in age- and sex-specific cortico-hippocampal development and cognitive performance

Published: March 2021

AbstractTestosterone (T) and cortisol (C) are steroid hormones that have been argued to play opposing roles in shaping physical and behavioral development in humans. While there is evidence linking T and C to different memory processes during adulthood, it remains unclear how the relative levels of T and C (TC ratio) may influence brain and behavioral development, whether they are influenced by sex of the child, and whether or not they occur as a result of stable changes in brain structure (organizational changes), as opposed to transient changes in brain function (activational changes). As such, we tested for associations among TC ratio, cortico-hippocampal structure, and standardized tests of executive, verbal, and visuo-spatial function in a longitudinal sample of typically developing 4–22-year-old children and adolescents. We found greater TC ratios to be associated with greater coordinated growth (i.e. covariance) between the hippocampus and cortical thickness in several areas primarily devoted to visual function. In addition, there was an age-related association between TC ratio and parieto-hippocampal covariance, as well as a sex-specific association between TC ratio and prefrontal-hippocampal covariance. Differences in brain structure related to TC ratio were in turn associated with lower verbal/executive function, as well as greater attention in tests of visuo-spatial abilities. These results support the notion that TC ratio may shift the balance between top-down (cortex to hippocampus) and bottom-up (hippocampus to cortex) processes, impairing more complex, cortical-based tasks and optimizing visuospatial tasks relying primarily on the hippocampus.
