AbstractRaman spectroscopy is frequently implemented in the analysis of art objects. Especially its non‐destructive character and the advent of mobile instruments, often equipped with fibre optics probe heads, have opened the doors for many direct investigations of artworks. However, Raman spectroscopy usually requires stable positioning of the objective lens, close to the paint surface. Consequently, and despite the use of an extensive range of positioning equipment, it is not possible to reach every spot of a large artefact. Positioning, and as a consequence measuring, is becoming even more critical for 3D objects. Therefore, we examine the characteristics and explore the opportunities for the investigation of art objects that can be obtained by using a zoom lens, which is suitable for the Raman investigation at working distances between 6 and 60 cm.

Published: October 2022

AbstractMetasurface‐assisted nanoprinting is usually enabled by spectrum‐modulation and/or polarization‐modulation at the subwavelength scale. The spectrum‐modulated nanoprint works under unpolarized white‐light and requires the minimalist observation conditions, but it can hardly modulate light brightness; the polarization‐modulated nanoprint can continuously control light brightness, but it requires complex and precise polarization control both at the input and output ends to decode a nanoprinting image. In this study, computer‐generated holographic nanoprinting is designed and experimentally demonstrated, enabled by Pancharatnam–Berry phase modulation of light, which has both the advantages of the two types of nanoprintings while avoiding their disadvantages. Specifically, a general platform is built to implement single‐channel/multichannel/color nanoprinting in a holography way, which presents its unique characteristics like incoherent light illumination, arbitrary brightness modulation, polarization insensitivity, and zero‐dispersion. A periodic phase is further attached to the target object wave during the holographic interference pattern generation, and the reconstructed nanoprinting image only appears in the zero‐order diffraction direction, thus making the information delivery safer. This study can empower advanced research on metasurface‐based nanoprinting, which can find its markets in ultracompact image‐display, data storage, information multiplexing, and many other related fields.

AbstractObjectivesThe Concise Health Risk Tracking Self‐Report (CHRT‐SR) assesses the risk of suicidal behavior. We report its psychometric properties in a representative sample of adolescent outpatients.MethodsA sample (n = 657) of adolescents (<18 years of age) in primary or psychiatric care completed the 14‐item version of CHRT‐SR at both baseline and within 3 months. To identify an optimal brief solution for the scale, we evaluated the factor structure of CHRT‐SR using multigroup confirmatory factor analysis, and testing measurement invariance across age and gender. The item response theory and classical test theory characteristics of the optimal solution were evaluated. Concurrent validity (both cross‐sectional and as a change measure over time) of the optimal solution was assessed by comparing it to another suicide measure.ResultsConfirmatory factor analysis identified the 9‐item CHRT‐SR (CHRT‐SR9) as the optimal solution. Classical test theory and item response theory indicated excellent fit. Concurrent validity analyses revealed that it can measure both improvement/worsening of suicidality over time.ConclusionThe CHRT‐SR9 is a brief self‐report with excellent psychometric properties in a sample of adolescents that is sensitive to changes in suicidality over time. Its performance in other populations and ability to predict future suicidal events deserves study.

AbstractAimsThis study investigated outcomes in community mental health research that were important to caregivers of people with schizophrenia.MethodsUsing an online survey conducted from August 1 to 31, 2020, data were collected from caregivers belonging to the LINE Schizophrenia Family Association. Caregivers identified outcomes important in community mental health research. Two researchers categorized caregivers' statements into research outcomes.ResultsA total of 132 caregivers completed the online selfreported questionnaire, and 296 caregiver statements were identified. Qualitative analysis identified 17 outcome categories. The caregivers tended to value having more free time, maintaining an appropriate relationship with people with schizophrenia, and being able to cope with their symptoms.ConclusionsThis exploratory study newly demonstrates the outcomes that caregivers of people with schizophrenia consider important in community mental health research. The findings may be useful in selecting outcomes for future studies of caregivers.

AbstractAimsA couple were referred for prenatal genetic testing at 31 weeks' gestation due to the presence of mild polyhydramnios and multiple central nervous system (CNS) abnormalities, including borderline ventriculomegaly, possible delayed sulcation, an enlarged cisterna magna and a small area of calcification around the posterior horns. Testing was initiated to identify any underlying genetic cause.Materials and MethodsRapid trio exome sequencing (ES) was performed on DNA extracted from parental blood samples and amniotic fluid.ResultsA pathogenic homozygous nonsense variant in KLHL7 (NM_001031710.2) associated with PERCHING syndrome (#617055) was identified.ConclusionWhilst there are detailed descriptions of the many postnatal phenotypes seen in these patients, there are few reports of features identified during pregnancy. This report is the first published prenatal diagnosis of PERCHING syndrome and provides further information on the associated fetal phenotypes.
ARGET ATRP of ethylene glycol dicyclopentenyl ether methacrylate with vegetable oil and terpene‐derived methacrylic monomers

Published: October 2022

AbstractHomo and statistical copolymerization reactions of ethylene glycol dicyclopentenyl ether methacrylate (EGDEMA) and a vegetable‐oil based methacrylic ester C13MA (average alkyl chain length = 13) are studied via activator regenerated electron transfer polymerization (ARGET ATRP) using only trace amounts of copper catalyst. Poly(EGDEMA) and poly(C13MA) homopolymers and statistical poly(EGDEMA‐stat‐C13MA) copolymers are cleanly synthesized with monomodal molecular weight distribution and dispersities Đ = Mw/Mn = 1.39–1.76 and Mn ~ 12 kg/mol. Chain end fidelity is confirmed by chain extension from poly(C13MA) macroinitiator with EGDEMA to make poly(C13MA‐b‐EGDEMA) diblock copolymers, which exhibit two distinct glass transition temperatures (Tgs), one for the poly(C13MA) block (−39°C) and the other for the poly(EGDEMA) block (23.9°C), suggesting microphase separation. Due to the relatively low Tg of poly(EGDEMA‐stat‐C13MA), terpene‐derived isobornyl methacrylate (IBOMA) is copolymerized with EGDEMA forming poly(EGDEMA‐stat‐IBOMA) statistical copolymers with Tgs ranging from 22.9–113°C. Additionally, crosslinking of the poly(EGDEMA) homopolymer and poly(EGDEMA‐stat‐C13MA) and poly(EGDEMA‐stat‐IBOMA) copolymers is achieved by UV thiol‐ene clicking of the pendent double bonds of EGDEMA units with suitable dithiols at 365 nm. For poly(EGDEMA), conversion of the thiol‐ene click reaction reaches 70%; where as the conversion of the clicking reactions is higher in the copolymers with a conversion up to 92% for poly(EGDEMA‐stat‐C13MA) and 97% for poly(EGDEMA‐stat‐IBOMA).
An integrated modelling framework for complex systems safety analysis
Authors: Tolo Silvia , Andrews John 
Published: October 2022

AbstractThe ever‐increasing complexity of engineering systems has fuelled the need for novel and efficient computational tools able to enhance the accuracy of current modelling strategies for industrial systems. Indeed, traditional Fault and Event Tree techniques still monopolize the reliability analysis of complex systems despite their limitations, such as the inability to capture underlying dependencies between components or to include degradation processes and complex maintenance strategies into the analysis. However, the lack of alternative solutions able to tackle large‐scale modelling efficiently has contributed to the continued use of such methodologies, together with their robustness and familiarity well rooted in engineering practice. The current paper defines a novel modelling framework for safety system performance which retains the capabilities of both fault and event tree methods, but also overcomes their limitations. The ambition is to provide a technique for application to real‐world systems preserving a familiar user–model interface and grounding the novel approach in well‐known and established reliability techniques. In order to describe the methodology developed and demonstrate its validity, five case‐studies referring to a simplified industrial plant cooling system are analysed and discussed. Further discussion regarding the scalability of the proposed approach is provided, outlining the advantages of the current implementation and its computational cost.

AbstractThis article describes the synthesis, characterization and photo‐physical studies of ZnO nanoparticles capped with monomer and polymer dyes D1 and D2, respectively; these dyes were synthesized by an easy and inexpensive condensation method by reacting Indole‐3‐carboxaldehyde with N,N‐dimethylethylenediamine and polyamine. The optoelectronic properties of these dyes were investigated by UV‐Vis spectroscopy. Further, these dyes D1 and D2 were decorated with ZnO nanoparticles and labelled as samples S1 and S2. The structural properties of dyes capped ZnO nanoparticles were characterized by X‐ray diffractogram, scanning electron microscopy, and dynamic light scattering studies. Further, S1 and S2 were deployed to fabricate photo‐anodes for ZnO solar cells, labelled as SC1and SC2, respectively. The results of investigations revealed that polymer dye molecules enhanced the photo‐harvesting capability of ZnO nanoparticles within the ZnO solar cell SC1. Maximum photo‐energy conversion efficiencyη =5.42 % was attained with solar cell SC2 under AM 1.5 solar irradiations. Comparatively, it has been observed that the recorded photovoltaic efficiency of solar cell SC2 was enhanced by 1.49 % comparative to the solar cell SC1. The IPCE spectra studies revealed a significant improvement of (15–19)% in the photo efficiency of solar cell SC2 than SC1.

AbstractMolecular structure of (E)‐N‐(4‐chlorobenzylidene)‐6‐methylbenzo[d]thiazol‐2‐amine, (E)‐N‐(4‐chlorobenzylidene)‐5‐chloropyridin‐2‐amine was determined in solution and solid states by various techniques such as UV/Vis, FT‐IR, NMR spectroscopy, HRMS and X‐ray diffraction. Both the Schiff base compounds crystallize as monoclinic system with identical space group P21/c. Supramolecular interactions observed in X‐ray structure are validated via density functional theory (DFT) calculations. Further, the reactivities of both compounds (ligands) are analysed with the help of frontier molecular orbitals (FMOs) analysis. They were treated with Cu and Ag salts to obtain corresponding coordination complexes. Both the ligands contain three possible coordination sites namely, endocyclic nitrogen, sulfur and the imine nitrogen. Among these nucleophilic centres, imine nitrogen is more basic and readily coordinates with Cu and Ag metals. The compounds were tested for their fluorescence properties and all the compounds were found to be fluorescence active. The Schiff base ligands and their complexes were also tested for preliminary biological activities such as antibacterial, antioxidant and enzyme inhibition. Molecular docking studies were implemented to compare and validate the enzyme inhibition potentials of ligands. Moderate activities were observed for all compounds. The activities of ligands enhanced by complexation with Cu(II) and Ag(I) metals ions.
Vacuum Pumping System for ITER's Deuterium Tritium Operational Campaign
Authors: Dremel Matthias , Banerjee Indranil , Shaun Hughes , Pearce Robert 
Published: October 2022

SummaryIn the ITER fusion experiment the torus vacuum pumping system is mainly involved in pumping plasma exhaust gases consisting of Deuterium/Tritium (DT) and trace quantity of helium. The currently proposed plasma operation plan for the six torus cryopumps is staggered for all fueling rate and plasma durations and therefore variable tritium inventories need to be handled. The ITER cryopumps and the backing vacuum pumping system are custom made tritium compatible pumping trains. Their compliant matrix not only asks for pumping efficiencies and hydrogen confinement but also respecting the specific tritium and deuterium (DT) inventories for measures on radiation protection and fire safety. In this article, we present a possible operation plan for torus vacuum pumping system in combinations with roughing pump trains for the ITER baseline plasma scenario. The operation of the vacuum system is driven by DT inventories in the different pumps and building sectors.The primary vacuum pump is torus cryogenic pump (TCP) followed backing roughing pump trains comprise the cryogenic viscous flow compressor (CVC), tritium compatible scroll and Roots pumps. The TCPs are regenerated during timed intervals for an uninterrupted and safe torus operation. Next to the demanding long pulse operation (1 hour) we present an operation plan for inductive short pulse (450 s), hybrid pulse (1000 s) and dwell time vacuum pumping operations [1]. However, the inductive and hybrid pulses are not as critical as long pulse operation pertaining to tritium and hydrogen inventory management.
Vakuumtechnik in der Rechtsmedizin

ZusammenfassungBei Leichenöffnungen sind Gerüche ein ständig begleitendes Element. In aller Regel sind diese sehr deutlich, aber selten ist der genaue Ort und die genaue Zusammensetzung bekannt. Erschwerend kommt hinzu, dass die Gasmengen in lokal sehr unterschiedlicher Menge auftreten. Teilweise befinden sich Gasblasen von 1 cm3 beispielsweise im Blutkreislauf. Diese geringen Gasmengen zuverlässig zu analysieren ist dem Labor für Vakuumtechnik der Frankfurt University of Applied Sciences gelungen. Zusätzlich sind sie in der Lage, nachzuweisen, welches Gas ein Mensch vor seinem Tod, als Letztes eingeatmet hat. Beide Methoden sind wichtige Indizien zur Ermittlung der Todesursache von Menschen.

Published: October 2022

AbstractA 10‐year‐old female desexed domestic shorthair cat was diagnosed by the regular veterinarian with large cell splenic lymphoma in June 2020. A splenectomy was performed; however, complications postoperatively and the owner's willingness to pursue chemotherapy resulted in the patient being referred to the oncology department of a local multidisciplinary specialist hospital. At referral, a hypertrophic cardiomyopathy (HCM) phenotype was diagnosed post an episode of dyspnea. The patient was treated with CMOP (cyclophosphamide, mitoxantrone, vincristine and prednisone) chemotherapy, resulting in remission of the lymphoma and the HCM phenotype. Twenty‐one months out from treatment, the patient was still in remission with no evidence of heart disease.
Material Traces of a Cumbersome Past: The Case of Italian Colonial History

Published: October 2022

AbstractPhysical daily contexts are replete with traces of the past. A statue in a park, the name of a street, or an old advertisement can all remind people of specific historical moments or periods. Often, they recall glorious episodes, but traces of less glorious pasts also persist. Among them, the most self-censored ones refer to past immoral actions that tarnish the overly idealized moral standard attributed to the group. As a case in point, material traces of the colonial past became the focus of controversies within formerly colonizing countries during the last decade. European anti-racist movements questioned the colonial heritage of European societies in an unprecedented manner and active social minorities also brought to the fore some traces still in the background of physical environments. Part of public opinion reacted by denouncing the “cancel culture” or the danger of “erasing” history. This chapter outlines a social psychological approach about contemporary perceptions and interpretations of still self-censored material traces of Italian colonialism. Results of a qualitative survey on Italian participants’ representations and attitudes toward a candy with a colonial wrapping will illustrate how Italian participants of different generations question this ephemeral trace and take on the challenge of a cumbersome past.
Video Surveillance and Public Space: Surveillance Society Vs. Security State
Authors: Lysova Tatiana 
Published: October 2022

AbstractSince the end of the last century, the number of video surveillance cameras installed in public spaces has increasingly grown worldwide. Although the installation of video surveillance should allegedly deter crime and improve the fear of crime and the perception of insecurity, the technology collects a vast number of traces of all the members of a population, regardless of their criminal intentions. In the academic literature, two main theoretical approaches have been formed to comprehend the role of video surveillance in public spaces: surveillance society and security state. Interestingly, both of them find their roots in Foucault’s ideas. The first one, surveillance society, is based on Foucault’s perspective on disciplinary power. The latter, the security state, draws on the notions of apparatus of security and governmentality. This chapter is undertaken with the aim of providing an overview of the key features of the two approaches and their comparison. Furthermore, it discusses the possibility of applying both theories to analyze video surveillance in public spaces as it could offer a deeper understanding of a complex interplay of different logics behind an ever-increasing data collection on members of society.
Traces and Their (In)significance
Authors: Rava Gabriella 
Published: October 2022

AbstractThe concept of trace is useful for a semiotic reflection upon what is left behind. Similar to the concepts of index and footprint, traces are traditionally described as already signs, or more precisely as something recognized as a sign (Violi, Riv Ital Filos Linguaggio, 2016, http://www.rifl.unical.it/index.php/rifl/article/view/365; Mazzucchelli, Riv Ital Filos Linguaggio, 2015, http://www.rifl.unical.it/index.php/rifl/article/view/312). This act of recognition is fundamentally dependent on a community’s work of interpretation, in order to actualize a potential narration lying in the trace, but what if the promised sense is not grasped? Adopting the notion of intentionality (Greimas and Courtés, Sémiotique: dictionnaire raisonné de la théorie du langage. Hachette, Paris, 1979) to include partially unconscious traces within the sphere of semiotic investigation, the article considers the possibility to conceive traces as paradoxical signs standing for nothing, i.e., signs of insignificance (Leone, On insignificance. The loss of meaning in the post-material age. Routledge, 2020). Through the analysis of digital traces and trolling, (in)significance is disputed on the basis of a proposed paradigm, within which even such seemingly accidental traces may possess profound significance within a digital network constructed of distributed subjectivity. One conclusion drawn from the example is that strong normative claims about what may qualify as significant often conceal an ideologically charged agenda. For this reason in particular, a detailed account of digital traces should be the highest priority of semiotics today.
Leaving a Trace: Donor Plaques as Material Evidences of Generosity?
Authors: Monier Anne 
Published: October 2022

AbstractContemporary philanthropy relies on a gift/counter-gift process: a person making a donation receives benefits for it, mostly financial (tax deductions) or symbolic (recognition). Donor recognition is an important part of philanthropy and comes in many forms. One of them is donor plaques—on walls, signs, or objects/buildings—associated with naming, i.e., the material traces of recognition that have the name of the donor on them. The analysis of donor plaques deepens our understanding of the way the act of giving leaves traces. What are these traces of philanthropy? How long do donor plaques stay on the walls of institutions? How are they negotiated? How do they change the urban landscape at a bigger scale? This chapter aims at understanding the specificity and the symbolic role of donor plaques as traces left voluntarily by philanthropic donors. Focusing on an understudied topic (philanthropic traces) and based on two qualitative research conducted in philanthropic settings, it questions the relationship elite donors have with time and space through the analysis of a concrete object (the plaque). It also examines the meaning of these traces (and the values they convey), as well as the power relations (and resistances) they create.
