description: Approximating marginals of a graphical model is one of the fundamental problems in the theory of networks. In a recent paper a method was shown to construct a variational free energy such that the linear response estimates, and maximum entropy estimates (for beliefs) are in agreement, with implications for direct and inverse Ising problems[1]. In this paper we demonstrate an extension of that method, incorporating new information from the response matrix, and we recover the adaptive-TAP equations as the first order approximation[2]. The method is flexible with respect to applications of the cluster variational method, special cases of this method include Naive Mean Field (NMF) and Bethe. We demonstrate that the new framework improves estimation of marginals by orders of magnitude over standard implementations in the weak coupling limit. Beyond the weakly coupled regime we show there is an improvement in a model where the NMF and Bethe approximations are known to be poor for reasons of frustration and short loops.

description: There is an ongoing debate about how best to feed the growing world population in the long run and associated implications for research and development. Some call for a new Green Revolution to secure the supply of staple foods, whereas others emphasize the importance of diversifying and improving people's diets. We aim to contribute to this debate by reviewing the case of wheat and maize value chains and their contribution to food security in Africa and Asia. We first identify drivers transforming food systems. We then apply these to the cereal value chains and disentangle their effects on food security. We thereby add to the three strands in the literature around production, consumption, and food system transformation and point to different research needs and recommendations for the future. The review highlights: (1) Wheat and maize production will be increasingly impaired by ecological drivers such as land degradation, water scarcity and climate change. (2) There are promising innovations to increase and maintain productivity, but constraints in adopting these innovations have to be overcome (i.e., access to seeds, finance, and education/training). (3) The drivers affect all four dimensions of food security, but first and foremost they determine the availability and stability of maize and wheat. This indirectly also influences the economic and physical access of people to maize and wheat. (4) Research tends to focus on improving the productivity and sustainability of wheat and maize farming which is largely interlinked with the availability dimension of food security. (5) The stability and utilization dimension of food security merits continued yet increased support. First, to address climate change and implications for biotic and abiotic stresses. Second, to promote healthier diets and enable the equitable transformation of food systems. © Copyright © 2021 Grote, Fasse, Nguyen and Erenstein.

description: To determine the validity of the validate the adult patient-reported outcome measure tools, the Michigan Retinal Degeneration Questionnaire (MRDQ) and Michigan Vision-Related Anxiety Questionnaire (MVAQ), in adolescent patients with inherited retinal diseases (IRDs). Ninety-one adolescent patients diagnosed with IRDs were recruited at the Hospital for Sick Children (University of Toronto) and the Kellogg Eye Center (University of Michigan). The patients were administered the MRDQ, MVAQ, and Patient Health Questionnaire-4 (PHQ-4). Test-retest variability was assessed in eighteen patients within 14 days of the initial administration. Adolescent responses were analyzed for validity and reliability. As a further validation step, comparisons were made to adult data from the original MRDQ and MVAQ studies to ensure consistency in response ranges. The existing MRDQ and MVAQ content and format could accurately detect the impact of IRD on activities of daily living in adolescents with IRDs. No floor/ceiling effects were identified, test-retest reliability was established (r = 0.73–0.86), and no items were excluded after differential item functioning analysis. Domain and trait associations with visual acuity and IRD phenotypes were similar between adolescents and adults. The MRDQ and MVAQ are psychometrically validated questionnaires for which we have shown validity for use in adolescent patients with IRDs.

De-growth vs. green growth? Let’s focus on the common ground to speed up the transition to sustainability!

description: In the light of anthropogenic climate change, a polarized discussion about the right measures to keep economic activity within the planet’s ecological boundaries has emerged: Advocates of de-growth argue that continuous GDP growth is impossible because of natural limits to growth. They call for measures to change individual consumption patterns, to constrain affluence in wealthy countries, and to reform the economic system in such a way that it can fulfil its functions even without continuously growing GDP. Advocates of green growth argue that GDP growth and ecological impacts are conceptionally independent and call for promoting entrepreneurial activity which facilitates the transition towards a carbon-neutral, circular economy without curtailing economic growth. At first sight, the two views appear in unresolvable conflict. After sketching the two approaches, we point towards their common ground and argue that the conflict may concern ideologies rather than evidence-based policy proposals. Taken seriously, both call e.g. for urgent action; for fundamental reforms to correct faulty price signals; for promoting a circular economy powered by regenerative energy sources; for political measures which enable sufficient life styles; and for evidence-based rather than ideological economic analysis. Focusing on this common ground may accelerate the vital transition to a sustainable economy.

description: State socialism failed due to its inner contradictions. Despite huge investments in R&D- intensive industries, the soviet-type economy collapsed in 1989 in Eastern Germany, and the market-based system in the Western part prevailed. We compare the two parallel existing innovation systems in Germany to shed light on the success and failure of the state-led innovation system. Based on newly created indicators from archive data we show in a natural experiment setting that modernization efforts in relation to GDP was much bigger in the socialist as compared to the market economy in the last decades.These achievements, however, could not fully unfold in favor of economic growth due to obstacles related to the setting of research priorities, innovation incentives, and knowledge flow.

description: Dynamic behavior of micro water droplet condensed on a lotus leaf with two-tier roughness is studied. Under laboratory environment, the contact angle of the micro droplet on single micro papilla increases smoothly from 80 deg to 160 deg during the growth of condensed water. The best-known "self-clean" phenomenon, will be lost. A striking observation is the out-of-plane jumping relay of condensed droplets triggered by falling droplets, as well as its sustained speed obtained in continuous jumping relays, enhance the automatic removal of dropwise condensation without the help from any external force. The surface tension energy dissipation is the main reason controlling the critical size of jumping droplet and its onset velocity of rebounding.

description: Gas chromatographs with electron capture detectors are widely used for the analysis of electron affine substances such as pesticides or chlorofluorocarbons. With detection limits in the low pptv range, electron capture detectors are the most sensitive detectors available for such compounds. Based on their operating principle, they require free electrons at atmospheric pressure, which are usually generated by a β- decay. However, the use of radioactive materials leads to regulatory restrictions regarding purchase, operation, and disposal. Here, we present a novel electron capture detector based on a non-radioactive electron source that shows similar detection limits compared to radioactive detectors but that is not subject to these limitations and offers further advantages such as adjustable electron densities and energies. In this work we show first experimental results using 1,1,2-trichloroethane and sevoflurane, and investigate the effect of several operating parameters on the analytical performance of this new non-radioactive electron capture detector (ECD). © Author(s) 2017.

description: In Deutschland – aber auch weltweit – hat die COVID-19-Pandemie schwerwiegende Auswirkungen auf die Gesellschaft und insbesondere das Gesundheitssystem. Zum 2. Juni 2020 weist das Robert Koch-Institut (RKI) für Deutschland insgesamt 182.028 laborbestätigte COVID-19-Fälle aus, darunter 8.522 Todesfälle in Zusammenhang mit COVID-19. 86 % dieser Todesfälle und 16 % aller infizierten Personen waren dabei 70 Jahre oder älter. Vor allem ältere und pflegebedürftige Menschen sind bei einer Infektion mit dem SARS-CoV2-Virus von schweren Krankheitsverläufen und einer hohen Mortalität betroffen. Pflegekräfte wiederum haben aufgrund des direkten Kontaktes mit Pflegebedürftigen ein hohes Risiko an COVID-19 zu erkranken. Aufgrund der Vielzahl potentiell Betroffener (bundesweit 3,4 Mio Pflegebedürftige und 1,2 Mio. Beschäftigte in Einrichtungen der stationären und ambulanten Langzeitpflege) sollte in der vorliegenden Pandemie-Situation daher ein besonderes Augenmerk auf den Bereichen der ambulanten und stationären Langzeitpflege liegen – auch mit Blick auf eine mögliche zweie Pandemie-Welle. Derzeit fehlen jedoch valide Daten zur Situation von Einrichtungen der ambulanten und stationären Langzeitpflege, die es Leistungserbringern aber auch politischen Akteuren ermöglichen, auf die Herausforderungen und Unterstützungsbedarfe aufgrund der Pandemie organisatorisch und administrativ zu reagieren. Die Universität Bremen hat daher vom 28. April bis zum 12. Mai 2020 eine deutschlandweite Online-Befragung in (teil-)stationären und ambulanten Pflegeeinrichtungen durchgeführt. Knapp 18.000 Einrichtungen wurden mit Fragen zu Strukturmerkmalen, zum Vorkommen des SARS-CoV-2-Virus in den Einrichtungen, Auswirkungen der Pandemie z. B. in Bezug auf personelle und sachliche Ausstattung aber auch zu veränderten Arbeitsprozessen und Kommunikationsstrukturen per Email angeschrieben und zusätzlich über Verbände auf die Umfrage hingewiesen. Von 701 Pflegediensten, 96 teilstationären und 824 stationären Einrichtungen liegen nunmehr Daten vor. In Bezug auf zentrale Strukturmerkmale entspricht die Verteilung der beteiligten Einrichtungen dabei im Wesentlichen der bundesweiten Verteilung.

description: Polysialic acid (polySia) is a carbohydrate polymer of varying chain length. It is a promising scaffold material for tissue engineering. In this work, high chain length polySia was produced by an Escherichia coli K1 strain in a 10-L bioreactor in batch and fed-batch mode, respectively. A new downstream process for polySia is presented, based on membrane adsorber technology and use of inorganic anion exchanger. These methods enable the replacement of precipitation steps, such as acetone, cetavlon, and ethanol precipitation of the already established purification process. The purification process was simplified, while process efficiency and product qualities were improved. The overall yield of polySia from a 10-L batch cultivation process was 61% and for 10-L fed-batch cultivation process the yield was 40% with an overall purity of 98%. The endotoxin content was determined to be negligible (14 EU mg-1). The main advantage of this new downstream process is that polySia with high chain length of more than 130 degree of polymerization can be obtained. In fed-batch cultivation, chain lengths up to 160 degree of polymerization were obtained.

description: In vielen Ländern legen die Normen IEC 61000-3-3 [1] und IEC 61000-3-11 [2] verbindlich fest, welche Spannungsschwankungen von Geräten am öffentlichen Stromversorgungsnetz erzeugt werden dürfen. Die Festlegungen dienen unter anderem der Begrenzung von Licht-Flicker und beruhen auf der alten Annahme, dass in einem Haushalt vorwiegend Glühlampen zur Beleuchtung verwendet werden. Da die Glühlampentechnologie jetzt vom Markt verschwindet, ergibt sich eine neue Situation. Dieser Beitrag beschreibt, wie unter den neuen Bedingungen die EMV bezüglich Licht-Flicker aufrechterhalten werden soll.

description: Coauthors (CA) of a "lead investigator" (LI) can receive a rank (r) according to their "importance" in having published joint publications with the LI. It is commonly accepted, without any proof, that publications in peer review journals and e.g. conference proceedings do not have the same "value" in a CV. Same for papers contributed to encyclopedia and book chapters. It is here examined whether the relationship between the number (J) of publications of some scientist with her/his coauthors, ranked according to their decreasing importance, i.e. $ J \propto 1/r^α $, as found by Ausloos, still holds if the overall publication list is broken into such specific types of publications. Several authors, with different careers, but mainly having worked in the field of statistical mechanics, are studied here to sort out answers to the questions. The exponent $α$ turns out to be weakly scientist dependent, only if the maximum value of J and r is large and is $\sim +1$ then. The $m_A$ core value, i.e. the core number of CAs, for proceedings only is about half of the total one, i.e. when all publications are counted. Contributions to the numerical values from both encyclopedia and book chapters are marginal. The role of a time span on $m_A$ is also examined in two cases in relation to career activity considerations. It can considered that the findings serve as a contrasting point of view on how to quantify an individual (publication) career as recently done by Petersen et al., here emphasizing the collaboration size and evolution, rather than a citation count, moreover specifying the type of publication. Through the various $m_A$'s one can distinguish different behavior patterns of a scientist publication with CAs.

description: Technological progress leads to the development of robots that are more error-prone and fragile than their predecessors. As a consequence, the utilization of the existing automation capital stock is associated with higher wear and tear, CPU overload or communication downtime and, as a consequence, an increase of depreciation costs. This in turn affect new investments in the future. Considering a growth model with physical and automation capital utilization, we argue that in a fully automated society, the utilized automation capital is a perfect substitute for labor, not the automation capital stock per se. We show that it is not necessarily the introduction of capital utilization by itself, but the relationship between the elasticities of utilization of automation and physical capital that plays a crucial role in slowing down the convergence speed in a model that reflects an automated society.

description: Microfluidic integration of biosensors enables improved biosensing performance and sophisticated lab-on-a-chip platform design for numerous applications. While soft lithography and polydimethylsiloxane (PDMS)-based microfluidics are still considered the gold standard, 3D-printing has emerged as a promising fabrication alternative for microfluidic systems. Herein, a 3D-printed polyacrylate-based microfluidic platform is integrated for the first time with a label-free porous silicon (PSi)–based optical aptasensor via a facile bonding method. The latter utilizes a UV-curable adhesive as an intermediate layer, while preserving the delicate nanostructure of the porous regions within the microchannels. As a proof-of-concept, a generic model aptasensor for label-free detection of his-tagged proteins is constructed, characterized, and compared to non-microfluidic and PDMS-based microfluidic setups. Detection of the target protein is carried out by real-time monitoring reflectivity changes of the PSi, induced by the target binding to the immobilized aptamers within the porous nanostructure. The microfluidic integrated aptasensor has been successfully used for detection of a model target protein, in the range 0.25 to 18 μM, with a good selectivity and an improved limit of detection, when compared to a non-microfluidic biosensing platform (0.04 μM vs. 2.7 μM, respectively). Furthermore, a superior performance of the 3D-printed microfluidic aptasensor is obtained, compared to a conventional PDMS-based microfluidic platform with similar dimensions.

Metal Deposition Chemistry for the Visualisation of Latent Fingermarks

Publisher: name: University of Leicester

Subjects: Uncategorized

description: Due to their unique nature, fingermarks are the prime means of identification of an individual. Operationally, the most useful marks are latent (non-visible) fingermarks, typically left by accidental contact, which must be visualised by chemical development techniques. There is a continuing need for simple, rapid, sensitive development techniques, involving safe reagents and ideally usable at a crime scene. This thesis addresses that challenge by galvanic deposition of one metal onto a less noble metal, using the fingermark residue as a barrier to the deposition process. Although successful at visualising fingermark, this technique is in a developmental stage and is not yet fully validated for standard use by practitioners. The primary focus was optimisation of galvanic deposition of copper to enhance marks on mild steel (iron containing) substrates, representative of knives, tools and other objects of forensic relevance. The quartz crystal microbalance (QCM) technique was used for gravimetric characterisation of the deposition/dissolution processes occurring during development. Of several reactions identified, galvanic copper deposition was dominant, accounting for 63% of the substrate mass change. The effects of temperature and alternative development solution delivery to the surface were explored. Based on highly successful latent fingermark development on iron by the copper reagent system, generalisation of the method to other substrates and metal ion reagent systems was explored. Thermodynamic considerations provided electrochemical criteria and revealed a number of candidate substrate/reagent combinations. Experimental measurements of the underpinning science were undertaken for two cases of potentially relevant forensic application, involving copper deposition on nickel and tin. After optimisation of immersion time and solution copper concentration, galvanic copper deposition on tin proved particularly successful for latent fingermark enhancement. The developed fingermarks were characterised and analysed using digital photography, image optimisation, scanning electron microscopy (SEM) and energy dispersive X-ray (EDX) analysis.

description: The sustainability transitions research field continues to broaden rapidly, engaging scholars from a wide variety of disciplinary backgrounds. As highlighted in the STRN research agenda, transitions research relies on a broad range of methodological approaches; yet the methodological diversity of transitions studies has remained somewhat limited. In this article, we investigate if this verdict still applies to transition studies published since 2016. While our findings suggest that the recent literature became methodologically more diverse especially with regard to theoretical frameworks and research questions, other methodological dimensions continue to suggest a lack of diversity. Based on our literature review we propose three particularly promising areas for further diversifying future research on socio-technical transitions towards sustainability: theoretical bridging, novel methods, and multi-scalarity across multiple sectors. © 2021

description: At the end of their operational life, offshore wind farms (OWF) have to be decommissioned. At present, there is little experience in decommissioning OWF. Due to the size and number of wind turbines, experiences can be transferred to the upcoming decommissioning of OWF only to a limited extent. The research project "SeeOff - Strategy development for efficient offshore wind farm decommissioning" has set itself the goal of supporting companies involved in OWF decommissioning in the development of sustainable OWF decommissioning strategies. We consider the decommissioning of OWF to be sustainable if it is cost-efficient, environmentally friendly as well as safe, fulfils all legal requirements and is publicly accepted. The research results are compiled in this "Handbook of offshore wind farm decommissioning". First, the requirements, especially of a legal, technical and organisational nature, for the decommissioning of OWF are presented (Chapter 2). For a reference OWF, decommissioning processes offshore and ashore, the associated technologies, logistics, procedures and resources are examined and described in detail (chapter 3). Based on this, ten decommissioning scenarios are developed and analysed in terms of their cost and resource efficiency, greenhouse gas emissions, occupational safety and impact on marine biodiversity. Within the framework of a multi-criteria decision analysis, a holistic evaluation of the decommissioning scenarios is carried out (Chapter 4). Finally, the research results, transferability of the decommissioning processes and the assessment approach and potential for improvement are discussed (Chapter 5).

description: The 2020 Decennial Census will be released with a new disclosure avoidance system in place, putting differential privacy in the spotlight for a wide range of data users. We consider several key applications of Census data in redistricting, developing tools and demonstrations for practitioners who are concerned about the impacts of this new noising algorithm called TopDown. Based on a close look at reconstructed Texas data, we find reassuring evidence that TopDown will not threaten the ability to produce districts with tolerable population balance or to detect signals of racial polarization for Voting Rights Act enforcement.

A Chandra X-ray study of the interacting binaries in the old open cluster NGC6791

description: We present the first X-ray study of NGC6791, one of the oldest open clusters known (8 Gyr). Our Chandra observation is aimed at uncovering the population of close interacting binaries down to Lx ~ 1e30 erg/s (0.3-7 keV). We detect 86 sources within 8 arcmin of the cluster center, including 59 inside the half-mass radius. We identify twenty sources with proper-motion cluster members, which are a mix of cataclysmic variables (CVs), active binaries (ABs), and binaries containing sub-subgiants. With follow-up optical spectroscopy we confirm the nature of one CV. We discover one new, X-ray variable candidate CV with Balmer and HeII emission lines in its optical spectrum; this is the first X-ray--selected CV confirmed in an open cluster. The number of CVs per unit mass is consistent with the field, suggesting that the 3-4 CVs observed in NGC6791 are primordial. We compare the X-ray properties of NGC6791 with those of a few old open (NGC6819, M67) and globular clusters (47Tuc, NGC6397). It is puzzling that the number of ABs brighter than 1e30 erg/s normalized by cluster mass is lower in NGC6791 than in M67 by a factor ~3 to 7. CVs, ABs, and sub-subgiants brighter than 1e30 erg/s are under-represented per unit mass in the globular clusters compared to the oldest open clusters, and this accounts for the lower total X-ray luminosity per unit mass of the former. This indicates that the net effect of dynamical encounters may be the destruction of even some of the hardest (i.e. X-ray--emitting) binaries.

description: Publications are an important measure of research productivity for scientists across all disciplines. As most science is done in teams, the author list is (or was) increasingly important. However, the order of names in the author list reflects often unwritten practices and conventions around authorship and varies across disciplines and research groups. As a result, the position in an author list often carries little information about what the contribution of each researcher was. This is disadvantageous for early career researchers as their contribution is more likely to be underestimated compared to senior authors. As a way out of this unfortunate situation, the Contributor Roles Taxonomy (CRediT) was developed - a formal taxonomy representing 14 roles typically played by contributors to scientific scholarly output. In this Workshop, CRedIT will be introduced, and we can exchange views on it.

description: Die ESD-Zerstörfestigkeit von einem 8-Bit Mikrocontroller und einem Audio-IC für tragbare Multimedia-Geräte wurde untersucht. Es wurde gezeigt, dass die UI-Kennlinien beider ICs im Vergleich zu ICs für Kfz-Anwendungen sich stark unterscheiden. Die Durchbruchspannung ist sehr gering. Trotz dieser Unterschiede wurde mit hoher Wahrscheinlichkeit ein thermischer Ausfall als ESD-Fehler nachgewiesen. Die ESD-Ausfalldetektion über die Eingangskennlinie stimmte mit einem Ausfallnachweis durch eine Funktionsüberprüfung überein. Eine Teil-Funktionalität kann aber auch nach Veränderung der Eingangskennlinie erhalten bleiben. Die Modellierung mit Kennlinienfunktionen wurde an den untersuchten ICs durchgeführt und in verschiedenen Aufbauten validiert. Anhand eines Demonstrators wurde gezeigt, dass trotz einer geringen Durchbruchspannung die System-ESD-Festigkeit unter Einsatz von Schutzelementen wie Multi- Layer-Varistoren deutlich erhöht werden kann. Es wurde auch nochmals deutlich gezeigt, dass das Zusammenspiel aller relevanten Komponenten und nicht die Einzelperformance für die ESD-Zerstörfestigkeit auf Systemebene ausschlaggebend ist. Die hier weiterentwickelte Simulationsmethodik ist in der Lage, dieses Zusammenspiel zu reproduzieren und ein Design bereits in der Entwicklungsphase ESD-sicher zu gestalten.

description: Machine Learning models are increasingly used for decision making, in particular in high-stakes applications such as credit scoring, medicine or recidivism prediction. However, there are growing concerns about these models with respect to their lack of interpretability and the undesirable biases they can generate or reproduce. While the concepts of interpretability and fairness have been extensively studied by the scientific community in recent years, few works have tackled the general multi-class classification problem under fairness constraints, and none of them proposes to generate fair and interpretable models for multi-class classification. In this paper, we use Mixed-Integer Linear Programming (MILP) techniques to produce inherently interpretable scoring systems under sparsity and fairness constraints, for the general multi-class classification setup. Our work generalizes the SLIM (Supersparse Linear Integer Models) framework that was proposed by Rudin and Ustun to learn optimal scoring systems for binary classification. The use of MILP techniques allows for an easy integration of diverse operational constraints (such as, but not restricted to, fairness or sparsity), but also for the building of certifiably optimal models (or sub-optimal models with bounded optimality gap).

description: In the charge-ordered phase of strongly doped manganites La$_{1-x}$Ca$_x$MnO$_3$ ($x \geq 0.5$) absorption lines appear in the terahertz spectral range for commensurate $x$ values right below the charge-ordering temperature. They are connected to acoustic phonons that become optically active by folding of the Brillouin zone. At lower temperatures a strongly asymmetric extra absorption band develops at frequencies corresponding to the position of the lowest-energy van Hove singularity in the reduced Brillouin zone. The band is assigned to the boson peak, i.e. to the excess of lattice vibrational states over the standard Debye contribution. The folded phonons and the boson peak do not show up for incommensurate calcium contents when no distinct Brillouin zone folding exists.
