description: We introduce NaturalInversion, a novel model inversion-based method to synthesize images that agrees well with the original data distribution without using real data. In NaturalInversion, we propose: (1) a Feature Transfer Pyramid which uses enhanced image prior of the original data by combining the multi-scale feature maps extracted from the pre-trained classifier, (2) a one-to-one approach generative model where only one batch of images are synthesized by one generator to bring the non-linearity to optimization and to ease the overall optimizing process, (3) learnable Adaptive Channel Scaling parameters which are end-to-end trained to scale the output image channel to utilize the original image prior further. With our NaturalInversion, we synthesize images from classifiers trained on CIFAR-10/100 and show that our images are more consistent with original data distribution than prior works by visualization and additional analysis. Furthermore, our synthesized images outperform prior works on various applications such as knowledge distillation and pruning, demonstrating the effectiveness of our proposed method.

description: A striking feature of the atmosphere of Titan is that no heavy noble gases other than argon were detected by the Gas Chromatograph Mass Spectrometer (GCMS) aboard the Huygens probe during its descent to Titan's surface in January 2005. Here we provide an explanation of the mysterious absence or rarity of these noble gases in Titan's atmosphere: the thermodynamic conditions prevailing at the surface-atmosphere interface of the satellite allow the formation of multiple guest clathrates that preferentially store some species, including all heavy noble gases, over others. The clean water ice needed for formation of these clathrates could be delivered by successive episodes of cryovolcanic lavas that have been hypothesized to regularly cover the surface of Titan. The formation of clathrates in the porous lavas and their propensity for trapping Ar, Kr and Xe would progressively remove these species from the atmosphere of Titan over its history. In some circumstances, a global clathrate crust with an average thickness not exceeding a few meters could be sufficient on Titan for a complete removal of the heavy noble gases from the atmosphere.

description: Asphaltene is the heaviest fraction of crude oil with a complicated structure consisting of peri-condensed aromatic rings and aliphatic chains. Precipitation, flocculation, flow of suspended particles, mechanical plugging, entrainment and adsorption are mechanisms that may lead to significant changes in production from reservoirs. Entrapment of asphaltene reduces the permeability of porous media and imposes flow assurance problems and formation damage. Nevertheless, many uncertainties remain in asphaltene adsorption as interfacial phenomenon, and the literature suffers from lack of experimental data. Being defined as adherence of asphaltene particles on pore walls, asphaltene adsorption may affect interfacial tension, contact angle, wettability, relative permeability, displacement performance of waterflooding and recovery factor. This work aims to investigate the dynamic adsorption of asphaltene in porous media and evaluate the consequent effects on two-phase flow in porous media. Experiments were conducted to investigate dynamic adsorption of asphaltene in sand packs at varying experimental conditions. Experimental parameters included water film salinity, presence or absence of water film, asphaltene concentration, clay content and compositional change due to solvent co-injection. The objective was to investigate their contribution on the level of adsorption in sand packs. Waterflooding was conducted prior and after the adsorption step to measure the effects on relative permeability and understand how the displacement performance and recovery are affected by asphaltene adsorption. Interfacial tension and contact angle were measured for various concentrations of asphaltene solution and brine iii salinities. Distribution analysis and reversibility of asphaltene adsorption were also addressed. In addition, simulation models were developed and validated using the obtained experimental data and finally were employed for an analysis of asphaltene adsorption. The selected parameters from the sensitivity analysis were employed in the history matching to tune the results with the measured values, determine the optimal values of parameters and observe the behavior of asphaltene related variables. Obtained results showed the influence of mentioned experimental parameters on level of asphaltene adsorption in porous media also their competitive roles on displacement performance of waterflooding and recovery. However, salinity of water phase proved to have the dominating effect on inhibition of asphaltene adsorption in porous media.

description: Procedural Content Generation via Machine Learning (PCGML) faces a significant hurdle that sets it apart from other fields, such as image or text generation, which is limited annotated data. Many existing methods for procedural level generation via machine learning require a secondary representation besides level images. However, the current methods for obtaining such representations are laborious and time-consuming, which contributes to this problem. In this work, we aim to address this problem by utilizing gameplay videos of two human-annotated games to develop a novel multi-tail framework that learns to perform simultaneous level translation and generation. The translation tail of our framework can convert gameplay video frames to an equivalent secondary representation, while its generation tail can produce novel level segments. Evaluation results and comparisons between our framework and baselines suggest that combining the level generation and translation tasks can lead to an overall improved performance regarding both tasks. This represents a possible solution to limited annotated level data, and we demonstrate the potential for future versions to generalize to unseen games.

Publisher: name: UNSPECIFIED
Year: 2023

description: The dissertation's central focus lies in investigating the influence of temporal, industry-specific, firm-specific, and project-specific factors on the stock market risk and return associated with corporate blockchain announcements. Structured into three chapters, the research employs theoretical frameworks and empirical analyses to uncover nuanced insights. Chapter 2, anchored in signaling theory, examines the general market impact of corporate blockchain announcements, considering temporal factors, cryptocurrency hype phases, and differences between US and EU-based companies. It reveals significant positive stock market returns associated with blockchain news, amplified by project success, business-relatedness, and cryptocurrency hype periods. Chapter 3 extends the analysis to industry-level factors, revealing that firms in the Information Technology industry benefit more from blockchain announcements. It explores additional project-level effects, such as blockchain partnerships and consortium joinings, and assesses their impact on market risk. The findings suggest that blockchain announcements do not substantially alter a firm's risk profile. Chapter 4 focuses on specific blockchain use cases, emphasizing environmental, social, and governance (ESG) issues. It uncovers significant positive market reactions to ESG-related blockchain announcements and explores shareholder returns in supply chain management and finance-related use cases. The study suggests that shareholders react more favorably to project-specific announcements and less favorably to initiatives involving external IT service providers. By thoroughly analyzing diverse factors, this dissertation contributes to the ongoing academic discourse on the valuation of blockchain technology, offering a comprehensive understanding of the dynamics shaping corporate market value and risk in the era of blockchain adoption.

description: Effect of He ion irradiation on three model Fe(100-x)Cr(x) alloys (x =5.8, 10.75 and 15.15) was investigated with the conversion electron Mössbauer spectroscopy. The study of the alloys irradiated with 25 keV ions revealed that the strongest effect occured in the Fe(84.85)Cr(15.15) sample where an inversion of a short-range-order (SRO) parameter was found. Consequently, the investigation of the influence of the irradiation dose, D, was carried out on the chromium-most concentrated sample showing that the average hyperfine field, , the average angle between the normal to the sample's surface and the magnetization vector, , as well as the actual distribution of Fe/Cr atoms, as expressed by SRO parameters, strongly depend on D. In particular: (a)  increases with D, and its maximum increase corresponds to a decrease of Cr content within the two-shell volume around the probe 57Fe nuclei by ~2.3 at%, decreases by ~13 degree at maximum, (c) SRO-parameter averaged over the two-shell volume increases with D from weakly negative value (indicative of Cr atoms clustering) to weakly positive value (indicative of Cr atoms ordering). The inversion takes place at D ca. 7 dpa.

description: Although our ability to collect personal information has increased dramatically through personal informatics tools such as personal digital tracking technologies for step counts, location, and more, minimal attention has been paid to designing tools to generate actionable insight from data. Self-reflection is important to generate these insights; however, without scaffolding to support the process, it is often ineffective. In this thesis, I introduce and explore shared reflection – the reciprocal process of reflecting on others’ data and having others reflect on one’s own data – as a means to bootstrap the reflection process. I synthesize literature on personal informatics and social learning theories, design and conduct a six-week personal data collection study, and evaluate the results. Shared reflection appears to show promise; however, users value privacy and control over their personal data when sharing in a social context. Finally, the potential application of shared reflection to new personal informatics tools is explored.

description: Distributed Constraint Satisfaction (DCSP) has long been considered an important problem in multi-agent systems research. This is because many real-world problems can be represented as constraint satisfaction and these problems often present themselves in a distributed form. In this article, we present a new complete, distributed algorithm called Asynchronous Partial Overlay (APO) for solving DCSPs that is based on a cooperative mediation process. The primary ideas behind this algorithm are that agents, when acting as a mediator, centralize small, relevant portions of the DCSP, that these centralized subproblems overlap, and that agents increase the size of their subproblems along critical paths within the DCSP as the problem solving unfolds. We present empirical evidence that shows that APO outperforms other known, complete DCSP techniques.

KPIs
Material behavior
sheet metal

description: Accurate simulation of sheet metal forming processes in a virtual environment requires a good understanding of the mechanical behavior of sheet metal. However, the characterization of the material behavior involves a timeconsuming and costly classical testing procedure. Due to that, standard mechanical tests are being overtaken by new testing methods. These present more complex configurations and, thus, richer mechanical fields, providing a greater variety of data on material behavior [1]. Full-field measurement techniques such as Digital Image Correlation (DIC) are able to extract data from the test, taking advantage of the large quantity of information they provide. Although several test designs have already been proposed, selecting the best test to calibrate a material model remains a key challenge [2]. This study aims at proposing Key Performance Indicators (KPIs) to rank mechanical tests based on their ability to improve the material behavior characterization process. Three different mechanical tests, obtained from distinct design approaches [3,4,5], are analyzed using the proposed KPIs. Numerical information is extracted from a uniaxial load test up to rupture. The performance of each test is then evaluated and compared based on their ability to provide accurate and reliable mechanical data for characterizing sheet metal behavior. The results show that the KPIs are effective in ranking the different test designs and in identifying the most informative test. This highlights the importance of considering the design of mechanical tests when characterizing sheet metal behavior and the potential benefits of using KPIs to guide this process.

description: Game level blending via machine learning, the process of combining features of game levels to create unique and novel game levels using Procedural Content Generation via Machine Learning (PCGML) techniques, has gained increasing popularity in recent years. However, many existing techniques rely on human-annotated level representations, which limits game level blending to a limited number of annotated games. Even with annotated games, researchers often need to author an additional shared representation to make blending possible. In this paper, we present a novel approach to game level blending that employs Clustering-based Tile Embeddings (CTE), a learned level representation technique that can serve as a level representation for unannotated games and a unified level representation across games without the need for human annotation. CTE represents game level tiles as a continuous vector representation, unifying their visual, contextual, and behavioral information. We apply this approach to two classic Nintendo games, Lode Runner and The Legend of Zelda. We run an evaluation comparing the CTE representation to a common, human-annotated representation in the blending task and find that CTE has comparable or better performance without the need for human annotation.

Vortex Formation and Shedding in the Wake of Surface-Mounted Finite Aspect-Ratio Square Cylinders

description: Bluff-body vortex shedding with focus on the turbulent wake of finite surface-mounted square cylinders at moderate Reynolds numbers is studied experimentally using particle image velocimetry (PIV) and hotwire anemometry (HWA). Emphasis is put on understanding the formation and growth process of vortices, their interaction and separation from the feeding shear layer. The conventionally described vortex shedding process is reassessed. It is concluded that contrary to the traditionally proposed mechanism, the mutual interaction between counter-rotating vortices is not the cause for the limit to vortex growth. Rather, the vortex growth is naturally limited and the feedback from the shed vortices serves to lock-in the shedding frequency. Furthermore, based on observation of the shedding of an isolated two-dimensional vortex, a length scale defined as the distance between the shear-layer edge and vortex center at the streamwise location of maximum vortex circulation is shown to result in a collapse of non-dimensional circulation. On the ground of scaling principles, this scale is shown to also result in a collapse of the shedding frequency. This work also resolves an apparent discrepancy in the literature with respect to the existence of symmetric and anti-symmetric shedding regimes. Using spatial cross-correlation, instantaneous phase relationships, and phase-averaged velocity data obtained from PIV and HWA, it is shown that the shedding in the wake of surface-mounted finite square cylinders is predominantly anti-symmetric and thus consistent with the von Kármán process. What had been interpreted as symmetric shedding appears to be a distortion of the regular shedding process. During periods of low-amplitude fluctuations, two counter-rotating vortices exist concurrently in the base region. However, counter-rotating vortices are still shed alternately.

description: The human face is a highly variable feature. Facial shape variation is seen between and within multiple populations. However, the source of this variation is mostly unknown. Furthermore, phenotypic variation is observed within syndromes that display a unique craniofacial phenotype. Because of this inherent variation, facial shape has a large clinical important and diagnostic significance. To explore facial shape variation, I have conducted several studies that examine the role of morphological integration in producing coordinated shape changes in the face. In these studies, I hypothesized that the size of the face and skull are correlated with facial shape; and that dysmorphic patients will display different morphological relationships between parts of the face, when compared to controls. These hypotheses were tested in several groups; namely healthy controls, patients with non-syndromic cleft lip and/or palate, and patients with ectodermal dysplasia. While these conditions have different etiologies, genetics, inheritance, mechanism of development, and resultant facial shape, using both of these patient groups has allowed me to explore these hypotheses in starkly different phenotypic groups. My studies have shown that the allometric factors of facial shape variation are complex and overlapping. Size represents a relatively small proportion of facial shape variation in humans. Furthermore, different classifications of cleft phenotypes are crucial when deciphering covariance structure in cleft individuals. Collectively, these studies have furthered the knowledge of complex craniofacial phenotypes, and have extended the knowledge on how allometry affects human facial shapes.

description: We study the electronic phases of the kagome Hubbard model (KHM) in the weak coupling limit around van Hove filling. Through an analytic renormalization group analysis, we find that there exists a sublattice interference mechanism where the kagome sublattice structure affects the character of the Fermi surface instabilities. It leads to major suppression of Tc for d+id superconductivity in the KHM and causes an anomalous increase of Tc upon addition of longer-range Hubbard interactions. We conjecture that the suppression of conventional Fermi liquid instabilities makes the KHM a prototype candidate for hosting exotic electronic states of matter at intermediate coupling.

description: In this letter, we analyze the carrier transit delay in graphene field-effect transistors (GFETs). GFETs are fabricated at the wafer-scale on sapphire substrate. For a device with a gate length of 210 nm, a current gain cut-off frequency fT of 18 GHz and 22 GHz is obtained before and after de-embedding. The extraction of the internal (Cgs,i, Cgd,i) and external capacitances (Cgs,ex and Cgd,ex) from the scaling behavior of the gate capacitances Cgs and Cgd allows the intrinsic (τ_int), extrinsic (τ_ext) and parasitic delays (τ_par) to be obtained. In addition, the extraction of the intrinsic delay provides a new way to directly estimate carrier velocity from the experimental data while the breakdown of the total delay into intrinsic, extrinsic, and parasitic components can offer valuable information for optimizing RF GFETs structures.

description: Egocentric action anticipation aims to predict the future actions the camera wearer will perform from the observation of the past. While predictions about the future should be available before the predicted events take place, most approaches do not pay attention to the computational time required to make such predictions. As a result, current evaluation schemes assume that predictions are available right after the input video is observed, i.e., presuming a negligible runtime, which may lead to overly optimistic evaluations. We propose a streaming egocentric action evaluation scheme which assumes that predictions are performed online and made available only after the model has processed the current input segment, which depends on its runtime. To evaluate all models considering the same prediction horizon, we hence propose that slower models should base their predictions on temporal segments sampled ahead of time. Based on the observation that model runtime can affect performance in the considered streaming evaluation scenario, we further propose a lightweight action anticipation model based on feed-forward 3D CNNs which is optimized using knowledge distillation techniques with a novel past-to-future distillation loss. Experiments on the three popular datasets EPIC-KITCHENS-55, EPIC-KITCHENS-100 and EGTEA Gaze+ show that (i) the proposed evaluation scheme induces a different ranking on state-of-the-art methods as compared to classic evaluations, (ii) lightweight approaches tend to outmatch more computationally expensive ones, and (iii) the proposed model based on feed-forward 3D CNNs and knowledge distillation outperforms current art in the streaming egocentric action anticipation scenario.

An Exploration of Comparative Judgement for Evaluating Writing Performances of the Austrian Year 8 Test for English as a Foreign Language
Creators: name: Sickinger, Beci
Publisher: name: Lancaster University
Year: 2025

description: Comparative judgement (CJ) is an evaluation method whereby a rank order is constructed from judges’ pairwise comparisons of performances. CJ has been shown to be reliable and practical in various contexts, but it is currently under-researched and under-utilised in second language (L2) language testing and as a method to evaluate performance dimensions/criteria independently. The present thesis investigated the use of CJ for the evaluation of lower-secondary school English as a Foreign Language (EFL) written performances from a national test in Austria. The study used a mixed-methods research design and consisted of two strands. In Strand 1, 27 participants (Austrian EFL educators) evaluated 300 EFL scripts using CJ: once holistically (judging all aspects of one script against all aspects of a second script) and once by each of a set of dimensions/criteria (judging the features of one performance dimension/criterion for one script against the equivalent features in a second script). Additionally, the participants rated the scripts using an analytic rating scale (the conventional rating method). CJ was found to be a reliable method of evaluating EFL scripts in all judgement sessions (scale separation reliability, the CJ measure taken over from Rasch modelling, ≥ .89). Experienced teachers with experience of evaluating similar scripts were reliable judges (infit values ≤ 1.5) and more reliable when using CJ than when rating. Participants reported considering a broader range of writing features when rating than when using CJ. In Strand 2, think-aloud protocols were collected from eight participants while they were judging scripts with CJ. Findings indicated two approaches to the CJ decision-making process for EFL lower-secondary scripts—one reflecting a more traditional rating approach and the other a quicker, reliable approach tailored to CJ. Overall, this thesis suggests that CJ can be a reliable and time-efficient evaluation method for EFL writing when used by trained raters and/or teachers who have experience of evaluating written performances in the classroom.

description: Differences in the presentation of depressive symptoms between Westerners and Chinese have been reported. These differences, and reported differences in cognition, provided the impetus for this investigation of cultural variation in cognitive processes in depression. Two studies were conducted that utilized data from the same three samples of Euro-Canadians, Chinese-Canadians, and Hong Kong Chinese. Self-construals were measured in the first study and a culture priming method was tested to make causal statements about the role of culture in rumination and avoidance, which were investigated in the second study. A culture prime effect was only found for the Euro-Canadians. The pattern of self-construals largely followed prediction, particularly in consideration of this prime effect; the Euro- and Chinese-Canadians reported greater independence than the Hong Kong Chinese, whereas the Chinese-Canadians and Hong Kong Chinese reported greater interdependence than the Euro-Canadians. The small and inconsistent associations between self-construals and cognitive vulnerability to depression suggested that self-construals may have had a minimal influence on levels of rumination and avoidance. However, the culturally graded nature of the samples, and the largely graded pattern of differences in levels of rumination and avoidance among the samples suggested that the present findings were attributable to some aspect of culture. The fact that the Euro-Canadians largely endorsed greater levels of rumination and cognitive behavioural avoidance than the Chinese samples parallels findings that Westerners psychologise depression more than Chinese. In contrast, avoidant coping was found to be greater among the Hong Kong Chinese, which suggests that avoidant coping may represent a different form of avoidance that is differentially prevalent among Chinese and Euro-Canadians. Differences across cultural groups were also found for the associations between levels of rumination and avoidance, and between levels of avoidance rumination and depressive symptoms. The pattern of findings provides evidence that culture influences the use and function of rumination and avoidance in association with depressive symptoms. These results also suggest further questions for empirical investigation. The strengths, limitations, and implications of the research were discussed.

description: In many applications of evolutionary algorithms the computational cost of applying operators and storing populations is comparable to the cost of fitness evaluation. Furthermore, by knowing what exactly has changed in an individual by an operator, it is possible to recompute fitness value much more efficiently than from scratch. The associated time and memory improvements have been available for simple evolutionary algorithms, few specific genetic algorithms and in the context of gray-box optimization, but not for all algorithms, and the main reason is that it is difficult to achieve in algorithms using large arbitrarily structured populations. This paper makes a first step towards improving this situation. We show that storing the population as a minimum spanning tree, where vertices correspond to individuals but only contain meta-information about them, and edges store structural differences, or patches, between the individuals, is a viable alternative to the straightforward implementation. Our experiments suggest that significant, even asymptotic, improvements -- including execution of crossover operators! -- can be achieved in terms of both memory usage and computational costs.

In addition NRQCD matrix elements which determine the properties of the quark-antiquark-gluon Fock state are determined. In particular, the probability amplitude to find the quark-antiquark pair in the color octet state, the mean gluon energy and the fraction of momentum carried by gluon, the relative velocity of the color-octet quark-antiquark-pair are calculated.

description: Privacy protection appears as a fundamental concern when personal data is collected, stored, and published. Several privacy protection methods have been proposed to address privacy issues in private datasets. Each method has at least one parameter to adjust the guaranteed level of privacy protection. As the privacy protection level increases, the dataset loses more information utility due to further application of data manipulation methods and/or access restriction rules. Consequently, balancing the trade ff between privacy and utility is a crucial step and so far no systematic mechanism exists to provide directions on how to establish values for privacy parameters such that a balanced privacy/utility tradeff is induced. A balanced privacy/utility tradeoff can be described as a level on which the stakeholders of data reach a consensus (in the sense that no single party would be wiling to act diff erently to change the agreed upon level). Game theory provides a natural solution to finding such balanced tradeoff s. In this thesis, we capture the essence of establishing balancing values for privacy parameters as an extensive-form game with incomplete and imperfect information. A high-level step-by-step guideline is provided on how to solve the generic game. We instantiate the generic game model for three different privacy protection methods and analytically solve each game. The games' solutions are further simulated for sample problem settings to study the effects of various problem parameters on the balancing values of privacy parameters. The game model and its solution contribute to the fulfillment of our objective of establishing balancing values for privacy parameters (of a chosen privacy protection method). In addition to our main objective, the proposed game model can be consulted to choose the most pro fitable privacy protection method based on the problem requirements. Benchmarking frameworks can also benefi t from our game solutions by using the balancing privacy parameter values as the reference points for the comparisons between different privacy protection methods. We believe that a first step towards improving the data collection and privacy protection procedures is to understand how much privacy is currently sacrificed to achieve information utility (at the steady states). The game-based solution provided in this thesis promotes a deeper understanding of how privacy and utility reach a balanced tradeoff within the current privacy protection methods.

description: We report on results of fully consistent N-body simulations of globular cluster models with N = 100 000 members containing neutron stars and black holes. Using the improved `algorithmic regularization' method of Hellstrom and Mikkola for compact subsystems, the new code NBODY7 enables for the first time general relativistic coalescence to be achieved for post-Newtonian terms and realistic parameters. Following an early stage of mass segregation, a few black holes form a small dense core which usually leads to the formation of one dominant binary. The subsequent evolution by dynamical shrinkage involves the competing processes of ejection and mergers by radiation energy loss. Unless the binary is ejected, long-lived triple systems often exhibit Kozai cycles with extremely high inner eccentricity (e > 0.999) which may terminate in coalescence at a few Schwarzschild radii. A characteristic feature is that ordinary stars as well as black holes and even BH binaries are ejected with high velocities. On the basis of the models studied so far, the results suggest a limited growth of a few remaining stellar mass black holes in globular clusters.

description: The paper has explored analogue of gravitational synchrotron massive particle and Penrose process in MOdified Gravity (MOG) known as Scalar-Tensor-Vector-Gravity (STVG). Investigation of the gravitational field around Kerr-MOG black hole showed that it has strong gravitational field with large horizon and can rotate faster than Kerr black hole due to the effect of STVG. We have studied influence of STVG in circular motion of massive particle around Kerr-MOG black hole and discussed the Innermost Stable Circular Orbit (ISCO) of massive test particle. It is shown that STVG plays a crucial role in energy extraction from a rotating black hole, with an energy efficiency of more than $100\%$ according to the Penrose process. Furthermore, we have explored the gravitational synchrotron radiation analogue produced by a massive particle orbiting around a Kerr-MOG black hole. It has been shown that the intensity of gravitational radiation from binary systems of stellar black holes (SBH) and supermassive black holes (SMBH).

description: As fosfodiesterases dos nucleótidos cíclicos (PDE) são enzimas que regulam os níveis celulares dos segundos mensageiros adenosina 3´,5´-monofosfato cíclico (AMPc) e de guanosina 3´,5´-monofosfato cíclico (GMPc) através do controlo das suas taxas de degradação. O aumento dos níveis intracelulares de AMPc e GMPc, através da inibição das PDE, constitui uma estratégia extremamente útil para a obtenção de diversos efeitos farmacológicos com aplicação clínica relevante. A diferente distribuição tecidular e celular e a grande diversidade na estrutura, regulação e função das isoenzimas de PDE permitem o desenvolvimento de inibidores seletivos para cada uma das isoenzimas, dotados de grande interesse farmacológico.
Neste artigo é feita uma revisão dos diferentes inibidores das PDE disponíveis no mercado farmacêutico nacional e internacional e das suas aplicações na terapêutica farmacológica. É ainda feita uma abordagem dos principais inibidores das PDE que se encontram atualmente em fase de investigação, bem como do potencial terapêutico da inibição de determinadas PDE.
Foi efetuada uma revisão da literatura científica, através da pesquisa bibliográfica na PubMed, utilizando os termos «cyclic nucleotide phosphodiesterases» e «phosphodiesterase inhibitors», para a obtenção de referências bibliográficas publicadas desde 1998 até ao momento atual. Foram ainda consultadas as bases de dados de medicamentos da Autoridade Nacional do Medicamento e Produtos de Saúde, I. P. (INFARMED), da European Medicines Agency (EMA) e da Food and Drug Administration (FDA) para pesquisa dos inibidores das PDE autorizados para utilização na prática clínica.
Atualmente, encontram-se disponíveis no mercado farmacêutico mundial 15 inibidores seletivos das PDE, utilizados como cardiotónicos, relaxantes do músculo liso vascular e brônquico, antitrombóticos, anti-inflamatórios e antidepressivos. Os inibidores das PDE disponíveis em maior número são os inibidores das famílias 3 e 5, mas existem muitos outros inibidores seletivos com interesse na terapêutica farmacológica e um número considerável de fármacos em fase de desenvolvimento para utilização clínica.

description: Health expectations are probability-driven beliefs regarding the likelihood of certain outcomes occurring, and are associated with health behaviours including adherence with treatment and satisfaction with medical care. Currently, little is known about the expectations that caregivers of individuals with dementia have concerning the illness trajectory and health care. Furthermore, few psychometrically-validated measures are available to assess these beliefs. A two-phase methodology was adopted to explore the diversity of caregiver expectations, and to develop a comprehensive item bank for measuring caregiver expectations. In the first phase, 17 caregivers participated in semi-structured interviews. Using an inductive thematic approach to analysis, five themes were identified including expectations of the diagnosis, memory declines, driving cessation, changes in basic activities of daily living, and end of life. In the second phase, a step-wise item review procedure was developed to derive individual items from the qualitative data, and to further refine the item bank.
