description: Στόχος της διπλωματικής εργασίας είναι η μελέτη της συμπεριφοράς των ανόργανων πολυμερών που προκύπτουν από αλκαλική ενεργοποίηση αποβλήτων παρουσία πλαστικών ινών. Στην πειραματική διαδικασία για την σύνθεση των γεωπολυμερών επιλέχθηκαν ως στερεά συστατικά το τούβλο, ως απόβλητο κατασκευών και κατεδαφίσεων (ΑΚΚ) και η μεταλλουργική σκωρία ως βιομηχανικό παραπροϊόν. Το διάλυμα ενεργοποίησης που χρησιμοποιήθηκε αποτελείται από πυριτικό νάτριο (Na2SiO3) και υδροξείδιο του νατρίου (NaOH). Αρχικά μελετήθηκε η επίδραση της συγκέντρωσης του διαλύματος και η θερμοκρασία θέρμανσης σε δοκίμια που παράγονται μόνο από αλκαλική ενεργοποίηση τούβλου ή σκωρίας. Η αντοχή σε θλίψη των παραγόμενων δοκιμίων ήταν ικανοποιητική για ενεργοποίηση με διάλυμα NaOH συγκέντρωσης 8 Μ κ θερμοκρασία ωρίμανσης 80 °C. Στις συνθήκες αυτές μελετήθηκε η συν- αξιοποίηση τούβλου και σκωρίας. Οι τιμές της αντοχής σε θλίψη παρουσίασαν αύξηση με την προσθήκη της σκωρίας στο αρχικό μίγμα συγκριτικά με το ανόργανο πολυμερές μόνο από τούβλο. Η πρώτη ύλη που επιλέχθηκε για την μελέτη της επίδρασης της προσθήκης πλαστικών ινών ήταν μείγμα τούβλου και σκωρίας σε αναλογία 1:1 κ.β, με συγκέντρωση διαλύματος NaOH 8 M και θερμοκρασία ωρίμανσης 80 °C. Οι ίνες προέρχονται από πλαστικά μπουκάλια νερού και κόπηκαν σε δύο μήκη 4- 6 mm και 8- 10 mm, με πάχος 0,1- 0,13 mm και πλάτος μικρότερο τους ενός χιλιοστού. Η προθήκη πλαστικών ινών στο μίγμα πραγματοποιήθηκε σε τρία διαφορετικά ποσοστά, 1 %, 2 % και 3 % κ.ό. Οδηγός για την σύγκριση αποτέλεσε δοκίμιο αναφοράς (control) που προήλθε από αλκαλική ενεργοποίηση των πρώτων υλών χωρίς τη χρήση πλαστικών ινών. Η αξιολόγηση έγινε με χρήση δοκιμών προσδιορισμού αντοχής. Προσδιορίσθηκε η αντοχή σε θλίψη των δοκιμίων, η οποία παρουσίασε μείωση μετά την προσθήκη των ινών. Αντιθέτως οι τιμές της αντοχής σε κάμψη ήταν ικανοποιητικές μετά την προσθήκη ινών μήκους 8- 10 mm. Συμπερασματικά η ανάμιξη τούβλου και σκωρίας κατά την αλκαλική ενεργοποίηση μπορεί να οδηγήσει σε συν- αξιοποίηση αποβλήτων. Η προσθήκη ινών PET δεν επηρέασε σημαντικά τις ιδιότητες των ανόργανων πολυμερών, δείχνει όμως να έχει αρνητική επίπτωση στην αντοχή σε θλίψη. Αποτελεί όμως μια αρχική προσπάθεια για την συν- αξιοποίηση των τεράστιων ποσοτήτων πλαστικών που παράγονται και χρησιμοποιούνται καθημερινά και αποτελούν σημαντική πηγή περιβαλλοντικής ρύπανσης.

description: The era of democratization which began in the mid-1980s has caused a new process of identity formation in Taiwan. Although the academic literature on this issue is abundant today, current research still struggles with a precise definition and concept of Taiwanese identity, in particular in terms of national identity. This paper assesses the debate on contemporary Taiwanese nationalism and national identity. In general, it confirms the observation made by manyscholars that the island's history and political development have led to contending or competing identities. This 'identity split' has not impeded Taiwan in becoming a nation in its own right, however. The ongoing process of nation-building on the island is essentially based on an overarching quest for sovereignty and the desire on the part of the people to soundly identify with their liberal democratic state. More recent trends, though, suggest that Taiwan's national identity may gradually be closing the gates to the prospect of 'one China,' transforming it from 'civic' into 'civic-cum-ethnic.' The PRC faces a dilemma in this respect: if it maintains its pressure on Taiwan, it will fuel Taiwanese nationalism even further. Should China choose to modify its position on the 'one China' principle and become more flexible, however, then it will encourage Taiwanese nationalism to consolidate the existing 'identity divide' between the island and the mainland, thus strengthening the Taiwanese nation.

Year: 2013

description: «Disputas de Amanguchi» é a expressão pela qual designamos um conjunto de debates ocorridos entre 1551 e 1552, que tiveram como principais intervenientes o Padre Cosmede Torres (com o Padre Juan Fernandez como tradutor) e vários monges budistas. As principais fontes relativas a este acontecimento histórico são uma carta do Padre Cosme de Torres e outra do Padre Juan Fernandez. Estas cartas são, provavelmente,os primeiros textos ocidentais em que podemos encontrar relatos detalhados sobre o Budismo e que tiveram uma vasta posteridade nas crónicas portuguesas e europeiasrelativas às missões cristãs no Japão. O presente estudo procura reconstituir as referências ao Budismo nas cartas do Padre Cosme de Torres e do Padre Juan Fernandez,bem como os comentários das principais crónicas em Língua Portuguesa que se referem às «Disputas de Amanguchi»: História da Vida do Padre Francisco de Xavier, escritapelo Padre João de Lucena, e Oriente Conquistado a Jesus Cristo, do Padre Francisco deSousa. Desta forma, pretendemos analisar a evolução da controvérsia entre Cristianismo e Budismo, identificando, portanto, diferentes estádios de conhecimento do Budismo nos textos portugueses dos séculos XVI e XVII.

description: The semantic segmentation of surgical scenes is a prerequisite for task automation in robot assisted interventions. We propose LapSeg3D, a novel DNN-based approach for the voxel-wise annotation of point clouds representing surgical scenes. As the manual annotation of training data is highly time consuming, we introduce a semi-autonomous clustering-based pipeline for the annotation of the gallbladder, which is used to generate segmented labels for the DNN. When evaluated against manually annotated data, LapSeg3D achieves an F1 score of 0.94 for gallbladder segmentation on various datasets of ex-vivo porcine livers. We show LapSeg3D to generalize accurately across different gallbladders and datasets recorded with different RGB-D camera systems.

Gesellschaftliche Heterogenität, Staat und Demokratie in Ostasien

description: The current heterogeneity levels of East Asian countries can be traced back to long term evolutionary processes, mainly the development of traditional social organization, competitive state and empire building, and the impact of colonialism. The resulting levels of societal heterogeneity are highly relevant for political as well as socio-economic processes. This article analyzes the political relevance of ethnic, linguistic and religious heterogeneity in East Asia, comparing it to a sample of 90 African and Asian countries. Homogenous countries in East Asia as well as in the reference sample are not any more democratic than heterogeneous ones, but they seem to be in a better position to start and continue democratization. In striking contrast to the reference sample, there is no correlation between the heterogeneity level and the quality of government and state administration in East Asia. Some of the region's countries with rather high heterogeneity levels have managed to break this link. Many East Asian countries, however, are still far from achieving efficient and effective governance.

Reducing length of stay in a Respiratory Assessment Unit

Subjects: classificationCode: 420319
subject: Primary health care

description: National targets set out by the National Acute Medicine Working Programme highlights that all patients who present to these units should be seen within one hour, treatment should be initiated within six hours, and patients should be discharged or admitted as to an inpatient ward within forty-eight hours. Prolonged hospital length of stay increases the risk of patients developing hospital-acquired infections, increases risk of poor health outcomes, disrupts patient flow, and minimises access to care due to bed shortages. This project uses the DMAIC (Define, Measure, Analyse, Improve and Control) model for Quality Improvement to investigate the length of stay of patients admitted to an RAU in a large teaching hospital in North County Dublin, Ireland. Quality improvement tools were utilised, to identify the root cause for prolonged length of stay. Data revealed that the mean length of stay in the RAU was 6 days, with 7% of patients admitted to the RAU were transferred from an inpatient ward, and 40% of patients being cared for in the RAU did not have a respiratory condition. These results demonstrate a need for admission criteria to the RAU to prioritise patients being treated in the unit. An admission criteria checklist will help RAU staff determine what patients are suitable to be seen in the unit and will result in the RAU being used for its proposed purpose.

description: In both industrial and service domains, a central benefit of the use of robots is their ability to quickly and reliably execute repetitive tasks. However, even relatively simple peg-in-hole tasks are typically subject to stochastic variations, requiring search motions to find relevant features such as holes. While search improves robustness, it comes at the cost of increased runtime: More exhaustive search will maximize the probability of successfully executing a given task, but will significantly delay any downstream tasks. This trade-off is typically resolved by human experts according to simple heuristics, which are rarely optimal. This paper introduces an automatic, data-driven and heuristic-free approach to optimize robot search strategies. By training a neural model of the search strategy on a large set of simulated stochastic environments, conditioning it on few real-world examples and inverting the model, we can infer search strategies which adapt to the time-variant characteristics of the underlying probability distributions, while requiring very few real-world measurements. We evaluate our approach on two different industrial robots in the context of spiral and probe search for THT electronics assembly.

description: Pretende-se estudar a relação entre marga (ou caminho) do dharma budista e a viacrucis ou o sentido de kénosis (ou despojamento) cristão. Numa reflexão preliminar levantam-se enquadramentos e dificuldades deste contexto relacional na cultura e língua portuguesa, sobretudo a partir da sua tradição espiritual e cristã. Numa segunda parte, alargando-se o estudo ao diálogo ecuménico, chama-se a atenção para o âmbito espiritual do encontro. Tendo em conta as principais características do dharma budista, salienta-se a iluminação nirvânica e respectiva tipologia mística. Compara-se,depois, com o traço encarnacional e de sofrimento do caminho cristão revisto na kénosis de Cristo, interrogando-se convergência com o despojamento budista. Conclui-se pela necessidade de superar a linguagem do religioso em ordem a uma iluminativa consciência trans-linguística.

description: A novel continuum theory of incoherent interfaces with triple junctions is applied to study three-dimensional coupled grain boundary (GB) motion in polycrystalline materials. The kinetic relations for grain dynamics, relative sliding and migration of the boundary, and junction evolution are developed. In doing so a vectorial form of the geometric coupling factor, which relates the tangential motion at the GB to the migration, is also obtained. Diffusion along the GBs and the junctions is allowed so as to prevent nucleation of voids and overlapping of material near the GBs. The coupled dynamics has been studied in detail for two bicrystalline and one tricrystalline arrangements. The first bicrystal consists of two rectangular grains separated by a GB, while the second is composed of a spherical grain embedded inside a larger grain. The tricrystal has an arbitrary shaped grain embedded inside a much larger bicrystal made of two rectangular grains. In all these cases, analytical solutions are obtained wherever possible while emphasizing the role of various kinetic coefficients during the coupled motion.

description: A group signature scheme allows any group member to sign on behalf
of the group in an anonymous and unlinkable fashion. In the event of a dispute,
a designated trusted entity can reveal the identity of the signer. Group signatures
are claimed to have many useful applications such as voting and electronic cash.
A number of group signature schemes have been proposed to-date. However, in
order for the whole group signature concept to become practical and credible, the
problem of secure and efﬁcient group member revocation must be addressed. In
this paper, we construct a new revocation method for group signatures based on
the signature scheme by Ateniese et al. [ACJT]. This new method represents an
advance in the state-of-the-art since the only revocation schemes proposed thus
far are either: 1) based on implicit revocation and the use of ﬁxed time periods,
or 2) require the signature size to be linear in the number of revoked members.
Our method, in contrast, does not rely on time periods, offers constant-length
signatures and constant work for the signer.

description: Independente de um certo declínio nas práticas religiosas e do mito de que a religião se tornou irrelevante nas modernas sociedades europeias, parece que o mundo moderno é cada vez mais religioso. Neste sentido podemos testemunhar um ressurgimento religioso na política, um crescimento da pluralidade religiosa e um aumento das religiosidades ‘bricolage’. A religião continua a ser um fenómeno que necessita de investigações científicas e sistemáticas. Este artigo tenta explicar a expansão histórica e as condições contemporâneas do estudo das religiões enquanto disciplina científica singular. Um outro objectivo principal deste texto é o seguinte: Podemos compreender o estudo das religiões como uma aproximação monolítica ou interdisciplinar em fenómenos religiosos? E, finalmente, procurar-se-á expor algumas sugestões para uma organização metodológica do estudo das religiões.

description: The statistical study of voids in the matter distribution promises to be an important tool for precision cosmology, but there are known discrepancies between theoretical models of voids and the voids actually found in large simulations or galaxy surveys. The empirical properties of observed voids are also not well understood. In this paper, we study voids in an N-body simulation, using the ZOBOV watershed algorithm. As in other studies, we use sets of subsampled dark matter particles as tracers to identify voids, but we use the full-resolution simulation output to measure dark matter densities at the identified locations. Voids span a wide range of sizes and densities, but there is a clear trend towards larger voids containing deeper density minima, a trend which is expected for all watershed void finders. We also find that the tracer density at void locations is usually smaller than the true density, and that this relationship depends on the sampling density of tracers. We show that fits given in the literature fail to match the observed density profiles of voids. The average enclosed density contrast within watershed voids varies widely with both the size of the void and the minimum density within it, but is always far from the shell crossing threshold expected from theoretical models. Voids with deeper density minima also show much broader density profiles. We discuss the implications of these results for the excursion set approach to modelling such voids.

description: In recent years, the ability to assess the uncertainty of depth estimates in the context of dense stereo matching has received increased attention due to its potential to detect erroneous estimates. Especially, the introduction of deep learning approaches greatly improved general performance, with feature extraction from multiple modalities proving to be highly advantageous due to the unique and different characteristics of each modality. However, most work in the literature focuses on using only mono- or bi- or rarely tri-modal input, not considering the potential effectiveness of modalities, going beyond tri-modality. To further advance the idea of combining different types of features for confidence estimation, in this work, a CNN-based approach is proposed, exploiting uncertainty cues from up to four modalities. For this purpose, a state-of-the-art local-global approach is used as baseline and extended accordingly. Additionally, a novel disparity-based modality named warped difference is presented to support uncertainty estimation at common failure cases of dense stereo matching. The general validity and improved performance of the proposed approach is demonstrated and compared against the bi-modal baseline in an evaluation on three datasets using two common dense stereo matching techniques.

description: The New Horizons spacecraft, launched by NASA in 2006, will arrive in the Pluto-Charon system on July 14, 2015. There, it will spend a few hours imaging Pluto and its moons. It will then have a small amount of reserve propellant which will be used to direct the probe on to a second, yet to be discovered object in the Kuiper Belt. Data from the MegaPrime camera on CFHT was used to build a precise, high density astrometric reference frame for both the final approach into the Pluto system and the search for the secondary target. Pluto currently lies in the galactic plane. This is a hindrance in that there are potential problems with confusion. However, it is also a benefit, since it allows the use of the UCAC4 astrometric reference catalog, which is normally too sparse for use with MegaCam images. The astrometric accuracy of the final catalogs, as measured by the residuals, is 0.02 arcseconds.

description: The growing adoption of the Internet of Things (IoT) has brought a significant increase in attacks targeting those devices. Machine learning (ML) methods have shown promising results for intrusion detection; however, the scarcity of IoT datasets remains a limiting factor in developing ML-based security systems for IoT scenarios. Static datasets get outdated due to evolving IoT architectures and threat landscape; meanwhile, the testbeds used to generate them are rarely published. This paper presents the Gotham testbed, a reproducible and flexible security testbed extendable to accommodate new emulated devices, services or attackers. Gotham is used to build an IoT scenario composed of 100 emulated devices communicating via MQTT, CoAP and RTSP protocols, among others, in a topology composed of 30 switches and 10 routers. The scenario presents three threat actors, including the entire Mirai botnet lifecycle and additional red-teaming tools performing DoS, scanning, and attacks targeting IoT protocols. The testbed has many purposes, including a cyber range, testing security solutions, and capturing network and application data to generate datasets. We hope that researchers can leverage and adapt Gotham to include other devices, state-of-the-art attacks and topologies to share scenarios and datasets that reflect the current IoT settings and threat landscape.

description: Expomos, neste trabalho, o resultado de algumas reflexões sobre a gestão, o marketing e a sociologia do livro e da leitura, e um exercício de investigação de campo, efectuado junto de uma empresa sediada em Lisboa, que desenvolve a sua actividade editorial ecomercial, especialmente, no âmbito religioso. A empresa escolhida foi Paulinas Editora, e as razões da escolha assentaram, essencialmente, na necessidade de perscrutarmos o âmago de uma estrutura empresarial de pertença institucional religiosa – que actua, se desenvolve e evolui, regulando-se por critérios próprios do mundo laico –,para dela podermos colher alguns elementos com significado e substância que pudessem constituir uma amostra mínimamente indicativa de um nicho, particularmente específico, do mercado editorial e livreiro português e dos seus leitores.

description: Online product review networks play an important role in Internet commerce by transmitting
information that customers can use to evaluate physical products in a digitally mediated
marketplace. These networks frequently include an explicit social component allowing
consumers to view both how community members have rated individual product reviews and the
social status of individual reviewers. Moreover, the prior literature has not analyzed the impact of
these social cues on consumer behavior, focusing instead on the impact of aggregate review
ratings.

We extend this prior work by analyzing how these social factors impact consumer responses to
disaggregate review information. To do this, we use a new dataset collected from Amazon.com’s
customer reviews of books. This dataset allows us to control for the degree to which other
community members found the review helpful, and the reputation of the reviewer in the
community.

We find that reviews that the community finds helpful have a stronger impact on consumer
purchase decisions than other reviews do. Moreover, these reviews have a stronger impact on less
popular books than more popular books, where consumers may be able to use other outside
information sources to form an opinion of the product. We also find evidence consistent with the
hypothesis that featured reviews have a stronger impact on consumer purchase decisions than
other reviews do. Finally, contrary to our expectations, we do not find that more prominent
members of the community have a stronger impact on consumer purchase decisions than other
community members do. Overall, our results suggest that the micro-level dynamics of
community interactions are valuable in signaling quality — over-and-above the aggregate-level
summary quality scores. One important implication of this result is that the micro-level dynamics
of reputation communities make it harder for self-interested parties to manipulate reviews versus
an environment where an uninformative review from a new community member carries as much
weight as an informative review from an established and respected community member.

description: Observations of the S-stars, the cluster of young stars in the inner 0.1 pc of the Galactic Center, have been crucial in providing conclusive evidence for a supermassive black hole at the center of our galaxy. Since some of the stars have orbits less than that of a typical human lifetime, it is possible to observe multiple orbits and test the weak-field regime of general relativity. Current calculations of S-star orbits require slow and expensive computations in order to numerically solve geodesic equations for many small time steps. In this paper, we present a computationally efficient, first-order post-Newtonian model for the astrometric and spectroscopic data gathered for the S-stars. We find that future, 30-m class telescopes -- and potentially even current large telescopes with very high spectroscopic resolution -- may be able to detect the Shapiro effect for an S-star in the next decade or so.

Sentido da vida, desespero e transcendência

Publisher: name: Revista Lusófona de Ciência das Religiões
Year: 2013

description: O envelhecimento, a doença, o luto, a certeza da morte, claro, mas também o significado da procriação, a solidão, a banalidade do dia-a-dia – tudo, diz um filósofo –,nos oferece uma oportunidade de nos sentirmos perdidos se formos apenas morais. O sentido da vida é um problema espiritual que, desaparecida a grande religião, permanece, ou para nos atormentar ou para resolver os nossos tormentos.

A(s) igreja(s) face ao processo de recomposição do religioso; práticas e representações de jovens vinculados à estrutura da Igreja Católica romana

description: Com base num estudo empírico realizado entre 2001 e 2004, que incidiu sobre jovens leigos organizados formalmente na estrutura da Igreja Católica-romana e sujeitos a um processo de socialização religiosa institucional estruturado, propomo-nos discutir a incidência do processo de recomposição do religioso entre os jovens católicos praticantes no contexto português. Os resultados apontam, por um lado, para uma progressiva erosão das práticas e representações associadas à doutrina Católica-romana – o que se traduz numa heterogeneidade de posicionamentos que oscilam entre o integrismo intransigente e o progressismo radical – e por outro, verificámos que o envolvimento emocional, em detrimento do processo estruturado de formação, é neste caso o elemento central na vinculação ideológica confessional.

title: Emotionsregulationsstrategien bei negativen Emotionen in Zusammenhang mit Neurotizismus und Extraver
Creators: name: Zappe, Valentina
Year: 2023

description: Das Ziel dieser Studie ist es, zu untersuchen, ob Zusammenhänge zwischen den Persönlichkeitsdimensionen Neurotizismus und Extraversion und den verschiedenen Emotionsregulationsstrategien bestehen. Dabei wurden die Emotionsregulationsstrategien Ablenkung, Umbewertung, kontrollierter Ausdruck, unkontrollierter Ausdruck, empathische Unterdrückung und Akzeptanz in Bezug auf die negativen Emotionen Wut, Trauer und Angst untersucht. Dazu füllten 194 Personen online einen Selbstbeurteilungsfragebogen aus. Die Analyse zeigte einen negativen Zusammenhang zwischen Neurotizismus und kognitiver Umbewertung und drei Zusammenhänge zwischen Extraversion und den Emotionsregulationsstrategien: Zwischen Extraversion und kognitiver Umbewertung ergab sich eine negative Korrelation, eine positive Korrelation zeigte sich zum kontrollierten Ausdruck und eine weitere negative Korrelation zur empathischen Unterdrückung. In Hinblick auf diese Fragestellung wurden auch die möglichen Unterschiede zwischen den Geschlechtern untersucht, wobei die Analyse zeigte, dass Frauen häufiger, die Emotionsregulationsstrategie des kontrollierten Ausdrucks nutzen. Zukünftige Studien sollten auch die übrigen drei Persönlichkeits-dimensionen der „Big Five“ (Offenheit für neue Erfahrungen, Verträglichkeit und Gewissenhaftigkeit) in deren Forschung miteinbeziehen und die quantitativen Analysen mit qualitativen Untersuchungen der Emotionsregulationsstrategien ergänzen.
description: The aim of this study is to investigate whether there are correlations between the personality dimensions neuroticism and extraversion and different emotion regulation strategies. In doing so, the emotion regulation strategies distraction, reappraisal, controlled expression, uncontrolled expression, empathic suppression, and acceptance were examined in relation to the negative emotions anger, sadness, and fear. For this purpose, 194 participants completed an online self-report questionnaire. The analysis revealed a negative relationship between neuroticism and cognitive reappraisal and three relationships between extraversion and emotion regulation strategies: A negative correlation was found between extraversion and cognitive re-appraisal, a positive correlation was found for controlled expression, and another negative correlation was found for empathic suppression. Additionally, the possible differences between the sexes were also investigated. The analysis showed that women used the emotion regulation strategy of controlled expression more often than men. Future studies should also include the other three personality dimensions of the “Big Five” (openness to new experiences, agreeableness, and conscientiousness) in their research and complement the quantitative analyses with qualitative investigations of emotion regulation strategies.

description: Height models are a fundamental part of the geo-information required for various applications. The determination of height models by aerial photogrammetry, LiDAR or space images is time-consuming and expensive. For height models with large area coverage, UAVs are not economic. The freely available height models ASTER GDEM-3, SRTM, AW3D30 and TDM90 can meet various requirements. With the exception of ASTER-GDEM-3, which cannot compete with the other, the digital surface models SRTM, AW3D30 and TDM90 are analyzed in detail for accuracy and morphology in 4 test sites using LiDAR reference DTMs. The accuracy figures root mean square error, standard deviation, NMAD and LE90 are compared as well as the accuracy dependence on the terrain inclination. The analysis uses a layer for the open areas, excluding forest and settlement areas. Remaining elements that do not belong to a DTM are filtered. Particular attention is paid to systematic errors. The InSAR height models SRTM and TDM90 have some accuracy and morphological restrictions in mountain and settlement areas. Even so, the direct sensor orientation of TDM90 is better than for the other. Optimal results in terms of accuracy and morphology were achieved with AW3D30 corrected by TDM90 for the local absolute height level. This correction reduces the bias and also the tilt of the height models compared to the reference LiDAR DTM.

description: Living cells use readout molecules to record the state of receptor proteins, similar to measurements or copies in typical computational devices. But is this analogy rigorous? Can cells be optimally efficient, and if not, why? We show that, as in computation, a canonical biochemical readout network generates correlations; extracting no work from these correlations sets a lower bound on dissipation. For general input, the biochemical network cannot reach this bound, even with arbitrarily slow reactions or weak thermodynamic driving. It faces an accuracy-dissipation trade-off that is qualitatively distinct from and worse than implied by the bound, and more complex steady-state copy processes cannot perform better. Nonetheless, the cost remains close to the thermodynamic bound unless accuracy is extremely high. Additionally, we show that biomolecular reactions could be used in thermodynamically optimal devices under exogenous manipulation of chemical fuels, suggesting an experimental system for testing computational thermodynamics.

High Field Ultrasound Measurements in UPt3 and the Single Energy Scale Model of Metamagnetism

description: We report longitudinal ultrasound velocity measurements for magnetic fields up to 33 T applied parallel to the a-axis of the heavy electron compound UPt$_{3}$. A characteristic dip in the sound velocity at the metamagnetic critical field, $H_{c}=20$ T, reported in earlier work is reproduced and shown to be independent of temperature at very low temperatures. We show that the single energy scale model (B.S. Shivaram et al., Phys. Rev. B89, 241107(R), 2014) captures the observed key features of the field dependence in the sound velocity shift, $δv_{s}$. The shift $δv_{s}$ at $H_{c}$ is found to be inversely dependent on temperature above 3\thinspace K and assumes a fixed value at low T. This saturation in $δv_{s}$ below 3 K is accounted for by level broadening of the Uranium spin states.
