On the denoising of structural vibration response records from low-cost sensors: a critical comparison and assessment
Authors: Ravizza Gabriele , Ferrari Rosalba , Rizzi Egidio , Dertimanis Vasilis 
Published: July 2021

AbstractDue to the increasing quest of adopting low-cost sensors in structural health monitoring (SHM) processes, which may lead to detecting signals contaminated by significant levels of noise, the need to devise appropriate and effective denoising strategies, at the post-processing stage, is becoming more and more essential. Among several approaches proposed in the literature, it has been demonstrated that the employment of discrete wavelet transform (DWT) as a multi-rate filter bank, as well as the use of singular value decomposition (SVD), may result to be quite effective in signal denoising within various research fields, as biological, acoustic and mechanical. Here, DWT- and SVD-based denoising techniques are first independently reconsidered and reimplemented, aiming at exploring their optimal calibration in purifying noise-corrupted vibration response signals encountered in civil engineering applications. Then, a systematic performance evaluation is provided within a comparative framework, developed at an increasing level of noise affecting the measurements, in terms of noise-to-signal (N/S) ratio. In the study, two specific classes of synthetic response signals are first considered, namely earthquake and ambient vibration signals, since they may be assumed as representative of more general non-stationary and stationary signal typologies, respectively. To achieve a complete description of the clarified signal, strengths and weaknesses of the two denoising approaches are explored, in both time and frequency domains. The results prove the effectiveness of the analyzed implementations, especially in purifying seismic response signals, while some limitations may arise concerning the treatment of ambient vibration signals, in particular for the DWT-based denoising technique. Finally, a real case study is analyzed, where both denoising approaches are adapted and employed for clarifying acceleration signals detected on a modern short-span railway bridge, with rather satisfactory results, for both techniques.

AbstractPeptidoglycan recognition proteins (PGRPs) participate in insect defense against bacterial pathogens by recognizing bacterial cell wall peptidoglycans (PGNs). Here, we identified the PGRP-LB gene in the white-backed planthopper Sogatella furcifera (SfPGRP-LB). SfPGRP-LB is a secreted protein with a typical PGN-binding domain and five conserved amino acid (aa) residues required for amidase activity. Expression analysis showed that the SfPGRP-LB transcript levels were significantly higher in the midgut than in other tissues. Silencing SfPGRP-LB with dsRNA significantly downregulated the expression of Toll pathway genes Toll and Dorsal and Imd pathway genes Imd and Relish after Escherichia coli challenge. However, only Toll and Dorsal expressions were downregulated after Staphylococcus aureus challenge. E. coli and S. aureus challenges rapidly and strongly upregulated SfPGRP-LB expression. Recombinantly expressed SfPGRP-LB (rSfPGRP-LB) had strong affinities for E. coli Dap-type PGN and S. aureus Lys-type PGN and agglutinated the bacteria. However, rSfPGRP-LB inhibited S. aureus but not E. coli growth. Furthermore, rSfPGRP-LB had amidase activity, degraded Lys-type PGN, and destroyed S. aureus cell walls but had no such effects on E. coli Dap-type PGN. Thus, SfPGRP-LB recognizes and binds various bacterial PGNs but only has amidase activity against Lys-type PGN.

AbstractAdditional treatment options for coronavirus disease (COVID-19) are urgently needed, particularly for populations at high risk of severe disease. This cross-sectional, retrospective study characterized the outcomes of 43 patients with nosocomial severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection with and without treatment using monoclonal SARS-CoV-2 spike antibodies (bamlanivimab or casirivimab/imdevimab). Our results indicate that treatment with monoclonal antibodies results in a significant decrease in disease progression and mortality when used for asymptomatic patients with early SARS-CoV-2 infection.
Differential diagnosis of a thyroid mass, facial malar rash and ptosis on the flora in the primavera by Sandro Botticelli (1445–1510)
Authors: Ashrafian H. 
Published: July 2021

Abstract
Purpose
The Primavera is considered amongst the greatest and controversial artistic masterpieces worldwide painted by renaissance artist Sandro Botticelli. The aim was to identify any underlying medical foundations for the painting.

Methods
Observational study.

Results
The painting reveals, a ‘butterfly’ malar rash, bilateral ptosis and a clear neck swelling consistent with a goitre in the figure of Flora. This could be explained by concomitant Graves’ disease and systemic lupus erythematosus, or other presentations of multiple autoimmune syndrome.

Conclusion
These findings highlight the likely presentation of the earliest pictorial depictions of thyroid disease with systemic lupus erythematosus and emphasize the exactitude of depiction demonstrated by Botticelli in renaissance era.

ZusammenfassungFür einen inklusiven Fachunterricht, der sonderpädagogische und fachdidaktische Ansätze zum Umgang mit heterogenen Lernvoraussetzungen systematisch integriert, liegen bislang insbesondere in der Sekundarstufe kaum empirisch geprüfte Konzepte vor. Der Artikel stellt eine Pilotstudie zu einer Unterrichtseinheit zur Prozentrechnung vor, die mit vier Designprinzipien (verstehensorientierte Strukturierung auf mehreren Lernstufen, Darstellungsvernetzung, Sprachsensibilität und Sicherung der Zugänglichkeit) für den Unterricht in inklusiven Klassen konzipiert und realisiert wurde. Die Lernwirksamkeit der Einheit für alle Lernenden wurde in einem Prä-Post-Kontrollgruppendesign untersucht. Die Stichprobe bildeten insgesamt 259 Lernende in der Klassenstufe 7. Um die Interventionseffekte zu prüfen, wurden lineare hierarchische Regressionsanalysen durchgeführt. Die Ergebnisse zeigen, dass das mathematische Vorwissen die Posttest-Ergebnisse für Prozentverständnis am stärksten voraussagt, der Faktor Treatment am zweitstärksten. Die Interventionsgruppe (n = 169) mit dem inklusiven Unterrichtskonzept erzielt signifikant höhere Lernzuwächse im Prozentverständnis als die Kontrollgruppe (n = 90) im herkömmlichen Prozentrechenunterricht mit dem regulären Schulbuch. Dieser Befund kann als erster Hinweis auf die Wirksamkeit des Unterrichtskonzepts interpretiert werden, so dass sich Anschlussstudien zur generellen und differenziellen Wirksamkeit lohnen, welche die methodischen Limitationen überwinden.

Published: July 2021

ZusammenfassungTeilhabe und Partizipation werden in verschiedenen Fachdisziplinen thematisiert, wobei eine einheitliche Definition und Nutzung der Begriffe fehlen. Im Zuge der Neugestaltung der Eingliederungshilfe werden u. a. sozialgesetzliche Perspektiven auf Teilhabe und Partizipation, die eher den Rehabilitations- und Versorgungswissenschaften zuzuordnen sind, relevant für die inklusive Frühpädagogik. Diese werden in Verbindung mit der Internationalen Klassifikation der Funktionsfähigkeit, Behinderung und Gesundheit (ICF) vorgestellt und es werden Bezüge zu frühpädagogisch bedeutsamen Theoriediskursen und Forschungsständen hergestellt. Möglichkeiten der interdisziplinären Zusammenarbeit zur Teilhabeförderung in der inklusiven frühkindlichen Bildung und Frühförderung werden anhand der ICF aufgezeigt.
„Einfach hinnehmen“ – Partizipation bei der Leistungsbewertung
Authors: Marchand Silke , Spiegler Juliane 
Published: July 2021

ZusammenfassungPartizipation von Schülerinnen und Schülern gilt als wichtiges Element pädagogischen Handelns in der Demokratie, erweist sich aber in der Umsetzung als herausfordernd, da zwischen Lehrpersonen und Schülerinnen bzw. Schülern ein unaufhebbar asymmetrisches Verhältnis besteht. Es kommt in diesem Rahmen zu Partizipationssituationen, in denen die Autonomieansprüche, die mit der Forderung nach Partizipation verbunden sind, nicht eingelöst werden, auch wenn der Anschein erweckt wird, Mitbestimmung wäre möglich. Eine praxistheoretische Analyse einer Unterrichtsepisode zur Leistungsrückmeldung und -bewertung zeigt, wie die Praktiken des ‚doing student‘ und ‚doing participation‘ ineinander verschränkt sind und dazu beitragen, eine wirkmächtige Ordnung zu etablieren, in der oberflächlich Meinungsäußerungen möglich, aber inhaltliche Widerspruchsmöglichkeiten verwehrt sind. Die als partizipativ inszenierte Bewertung ihrer Leistung sollen die Schülerinnen und Schüler „einfach hinnehmen“.
Schüler*innenprotest – subversive Praxis oder Einlösung schulischer Partizipationsversprechen?
Authors: Eckermann Torsten 
Published: July 2021

ZusammenfassungIm Rahmen des Beitrags werden Ergebnisse aus einem laufenden ethnographischen Forschungsprojekt zur Schüler*innenprotestbewegung „Fridays-for-Future“ präsentiert. Erste rekonstruktive Analysen deuten dabei darauf hin, dass aus Sicht der protestierenden Schüler*innen der Grundschule als Bildungsinstitution eine besondere Relevanz für die Etablierung klimaprotektiver Praktiken zukommt, wobei vor allem Grundschulen mit einem spezifischen Profil („Draußenschule“, „Klimaschule“) adressiert werden. Gleichwohl ein dezidiert schuloppositionelles Verhalten nicht zu identifizieren ist, sondern die Schüler*innenprotestbewegung die Grundschule eher als ‚verlängerten Arm‘ der politischen Agenda entwirft, bedienen sie sich subversiver Praktiken, indem sie punktuell die gesetzliche Schulpflicht außer Kraft setzen. Der Beitrag lenkt den Fokus auf die bislang vernachlässigte Partizipation von Grundschüler*innen an den Protestpraktiken aus der Sicht jugendlicher Aktivistinnen und nimmt dabei in den Blick, wie sich der Schüler*innenprotest zur Schule ins Verhältnis setzt.
Tandem Deep Learning Side-Channel Attack on FPGA Implementation of AES
Authors: Wang Huanyu , Dubrova Elena 
Published: July 2021

AbstractSide-channel attacks have become a realistic threat to implementations of cryptographic algorithms, especially with the help of deep-learning techniques. The majority of recently demonstrated deep-learning side-channel attacks use a single neural network classifier to extract the secret from implementations of cryptographic algorithms. The potential benefits of combining multiple classifiers using the ensemble learning method have not been fully explored in the side-channel attack’s context. In this paper, we propose a tandem approach for the attack in which multiple models are trained on different attack points but are used in parallel to recover the key. Such an approach allows us to considerably reduce (33.5% on average) the number of traces required to recover the key from an FPGA implementation of AES by power analysis. We also show that not all combinations of classifiers improve the attack efficiency.
Does Medicaid Cover Penile Prosthesis Surgery? A State-by-State Analysis

Published: July 2021

ABSTRACTBackgroundMalleable [MPP] and inflatable [IPP] penile prosthesis surgery for the management of erectile dysfunction is a reliable treatment option with high success rates and excellent patient satisfaction; however, Medicaid coverage transparency is poor leaving a knowledge gap in this population.AimThe present study seeks to assess Medicaid coverage for MPP and IPP by state as evidenced by inclusion in publicly available physician fee schedules.MethodsState Medicaid websites were utilized to access public physician fee schedules. Individual search queries were performed for CPT codes 54400 and 54405 which represent insertion of MPP and IPP, respectively. Data were recorded for each device, including the coverage status, physician fees, and the presence of clear documentation of a prior authorization requirement.OutcomesMedicaid physician fee schedules were accessible for 49 out of 50 US states, and 28 states reported coverage for at least one type of penile prosthesis.RESULTSTwo states reported coverage for MPP only, one state reported coverage for IPP only, and 24 states reported coverage for both devices. One state reported that it did not cover either device, but listed coverage for a self-contained IPP (CPT 54401) only. Mean physician reimbursement was $477.15 (290.82–$1175.50) for MPP placement and $691.76 (421.68–$1794.27) for IPP. Eleven states documented prior authorization requirements within their fee schedules, while the remaining 17 states did not. Criteria for approval for prior authorization were not clearly stated in any fee schedule.Clinical ImplicationsEfforts to clearly document approval criteria and educate Men’s Health providers on available coverage could result in a significant improvement in sexual satisfaction in the Medicaid population.Strengths and LimitationsGraphical representation of states offering Medicaid penile prosthetic coverage and physician reimbursement ranges are provided with comparison to Medicare rates. Limitations include heterogeneity in fee schedules, lack of prior authorization requirement details, inability to correlate to successful claims data, and the evolving nature of Medicaid coverage for the given procedures.CONCLUSIONSMedicaid coverage exists for penile prosthetic surgery in 28 states, although often with significant, non-transparent prior authorization criteria.

ABSTRACT:The brain has the innate ability to undergo neuronal plasticity, which refers to changes in its structure and functions in response to continued changes in the environment. Although these concepts are well established in animal slice preparation models, their application to a large number of human subjects could only be achieved using noninvasive brain stimulation (NIBS) techniques. In this review, we discuss the mechanisms of plasticity induction using NIBS techniques including transcranial magnetic stimulation (TMS), transcranial direct current stimulation (tDCS), transcranial alternating current stimulation (tACS), random noise stimulation (RNS), transcranial ultrasound stimulation (TUS), vagus nerve stimulation (VNS), and galvanic vestibular stimulation (GVS). We briefly introduce these techniques, explain the stimulation parameters and potential clinical implications. Although their mechanisms are different, all these NIBS techniques can be used to induce plasticity at the systems level, to examine the neurophysiology of brain circuits and have potential therapeutic use in psychiatric and neurological disorders. TMS is the most established technique for the treatment of brain disorders, and repetitive TMS is an approved treatment for medication-resistant depression. Although the data on the clinical utility of the other modes of stimulation are more limited, the electrical stimulation techniques (tDCS, tACS, RNS, VNS, GVS) have the advantage of lower cost, portability, applicability at home, and can readily be combined with training or rehabilitation. Further research is needed to expand the clinical utility of NIBS and test the combination of different modes of NIBS to optimize neuromodulation induced clinical benefits.
Reductions in positive Clostridioides difficile events reportable to National Healthcare Safety Network (NHSN) with adoption of reflex enzyme immunoassay (EIA) testing in 13 Atlanta hospitals

AbstractIn total, 13 facilities changed C. difficile testing to reflexive testing by enzyme immunoassay (EIA) only after a positive nucleic acid-amplification test (NAAT); the standardized infection ratio (SIR) decreased by 46% (range, −12% to −71% per hospital). Changing testing practice greatly influenced a performance metric without changing C. difficile infection prevention practice.
Bed topography and marine ice-sheet stability
Authors: Sergienko Olga V. , Wingham Duncan J. 
Published: July 2021

AbstractThis paper examines the effect of basal topography and strength on the grounding-line position, flux and stability of rapidly-sliding ice streams. It does so by supposing that the buoyancy of the ice stream is small, and of the same order as the longitudinal stress gradient. Making this scaling assumption makes the role of the basal gradient and accumulation rate explicit in the lowest order expression for the ice flux at the grounding line and also provides the transcendental equation for the grounding-line position. It also introduces into the stability condition terms in the basal curvature and accumulation-rate gradient. These expressions revert to well-established expressions in circumstances in which the thickness gradient is large at the grounding line, a result which is shown to be the consequence of the non-linearity of the flow. The behaviour of the grounding-line flux is illustrated for a range of bed topographies and strengths. We show that, when bed topography at a horizontal scale of several tens of ice thicknesses is present, the grounding-line flux and stability have more complex dependencies on bed gradient than that associated with the ‘marine ice-sheet instability hypothesis’, and that unstable grounding-line positions can occur on prograde beds as well as stable positions on retrograde beds.

AbstractIn the present study, the influence of three sex ratios (1:1, 1:2, and 1:3; female:male) of the miridEngytatus varians(Distant) (Hemiptera) on different biological parameters and on its offspring was evaluated. The prey preference of different developmental stages of this predator for different nymphal instars (N) ofBactericera cockerelli(Sulcer) (Hemiptera: Triozidae) was also evaluated. The fertility was significantly higher (24 nymphs/female) in the 1:3 sex ratio than in the 1:1 and 1:2 sex ratios (14 and 16 nymphs/female, respectively). The females in the 1:1 and 1:2 sex ratios lived 1.14 and 1.43 days more (27 and 28 days, respectively) than those in the 1:3 sex ratio (26 days). The nymphs derived from the females of the three sex ratios (first filial generation, F1) had five instars and a duration of 17 or 18 days. The ratio of the F1generation females was not affected by the sex ratio of their parents. In choice tests, independent of whether the preys were placed on a single or multiple tomato (Solanum lycopersicumL.) leaflets, the consumption of females and males and N3, N4, and N5nymphs ofE. variansonB. cockerelli, generally showed the order of N2>N3>N4>N5. In conclusion, the findings revealed in this study can help to improve the rearing methodology for increasing populations ofE. varians. In addition, they can serve as a guideline for releasing this predator in times when there is an abundance of early instar nymphs ofB. cockerelli.

Published: July 2021

AbstractNew data have been obtained for three representatives of Exorchis; Exorchis convictus sp. n., Exorchis oviformis and Exorchis sp., from fish in the East-Asian region. For the first time, based on combined sequences of the ITS2 rDNA region and the 28S rRNA gene, Exorchis is confirmed to belong Cryptogonimidae. Based on analysis of a mitochondrial marker (cox1), the ‘Japanese’ and ‘Russian’ haplogroups are identified for E. oviformis isolated from Silurus asotus. One specimen of E. oviformis obtained in Japan is identical to the ‘Russian’ haplotype. Haplotype patterns are also observed for metacercariae of Exorchis sp. from Tanakia lanceolata and Carassius sp. fish in Kyushu Island (Japan).
Stressors and coping mechanisms of family care-givers of older relatives living with long-term conditions in mainland China: a scoping review of the evidence

AbstractAs the ageing population in China continues to grow, more people will be living with long-term health conditions and require support from family care-givers. This scoping review therefore aims to explore sources of stress and coping mechanisms adopted by care-givers of older relatives living with long-term conditions in mainland China. Literature searches were conducted in English (CINAHL, EMBASE, MEDLINE, PsycINFO and SCOPUS) and Chinese (CNKI, WANFANG DATA, CQVIP and CBM) databases between October and November 2019. The searches focused on the stressors and coping mechanisms utilised by family care-givers residing in the community. Narrative synthesis was used to identify themes within the data. Forty-six papers were included: 20 papers from English and 26 from Chinese databases. Six themes captured stressors: care-giving time (N = 22), financial resources (N = 17), role and personal strains (N = 42), preparedness (N = 4), social roles (N = 10) and lack of adequate formal support (N = 22); and one theme captured coping (N = 14). Unmet needs of care-givers of older relatives in mainland China were found to be extensive. Only a few studies had attempted to explore the causal link between stressors, coping and the influence of culture. Findings underscore the significance of adequately capturing intricacies around care-givers’ unmet needs, rather than generalising on the basis of culture. Qualitative studies are critical to providing a better understanding of the relationship between stressors, coping and resources afforded to care-givers by their cultural environment. Having such understanding is crucial to inform the development of competent care, which promotes self-efficacy and self-actualisation in care-givers in mainland China.
