description: ContextThe COVID-19 pandemic has reignited a commitment from the health policy and health services research communities to rebuilding trust in healthcare and created a renewed appetite for measures of trust for system monitoring and evaluation. The aim of the present paper was to develop a multidimensional measure of trust in healthcare that: (1) Is responsive to the conceptual and methodological limitations of existing measures; (2) Can be used to identify systemic explanations for lower levels of trust in equity-deserving populations; (3) Can be used to design and evaluate interventions aiming to (re)build trust.MethodsWe conducted a 2021 review of existing measures of trust in healthcare, 72 qualitative interviews (Aug-Dec 2021; oversampling for equity-deserving populations), an expert review consensus process (Oct 2021), and factor analyses and validation testing based on two waves of survey data (Nov 2021, n = 694; Jan-Feb 2022, n = 740 respectively).FindingsWe present the Trust in Multidimensional Healthcare Systems Scale (TIMHSS); a 38-item correlated three-factor measure of trust in doctors, policies, and the system. Measurement of invariance tests suggest that the TIMHSS can also be reliably administered to diverse populations.ConclusionsThis global measure of trust in healthcare can be used to measure trust over time at a population level, or used within specific subpopulations, to inform interventions to (re)build trust. It can also be used within a clinical setting to provide a stronger evidence base for associations between trust and therapeutic outcomes.

description: The quantum Fisher information is a Riemannian metric, defined on the state space of a quantum system, which is symmetric and decreasing under stochastic mappings. Contrary to the classical case such a metric is not unique. We complete the characterization, initiated by Morozova, Chentsov and Petz, of these metrics by providing a closed and tractable formula for the set of Morozova-Chentsov functions. In addition, we provide a continuously increasing bridge between the smallest and largest symmetric monotone metrics.

description: The paper is concerned with efficient estimation of characteristics demand. We derive and estimate an inverse input demand system for quality characteristics by using 172,946 observations over 881 trading days in the Icelandic fish auctions. An improved estimation method based on an expanded random coefficient model is suggested as an alternative to the currently used two-stage method of Brown and Rosen (1982). The estimates demonstrate the improved efficiency of the suggested method. A number of empirical results emerge, including a general increase in the demand for quality.

description: Firms who sell a regional or specialty product often share a common or collective reputation, which is based on the group's aggregate quality. The dynamic problem of collective reputation is similar to the natural resource extraction problems. Therefore, for the analysis of this particular problem, we use differential games. If there is unrestricted access to a common property resource (the reputation stock), agents perceive its shadow value to be zero and extract too rapidly; i.e, they all "cheat" on quality, "milking" the rents generated by the existence of the resource (reputation stock). We show that when there exists a collective product reputation without firm traceability, the firms will extract too much from the stock of reputation. A firm is said to "extract" reputation from the reputation stock when it sells low-quality products at high prices given by the high past levels of quality. The firm builds on the group's reputation when it provides a product with a quality level which is higher than the expected level of quality. The results from this work support minimum quality standards for producer groups and regional and specialty products. This is in contrast to the findings of previous work. Finally, the implications of these results are discussed as they relate to the case study of Washington apples. We present the case of Washington apples in light of the results of the analytical model.

description: The temperature and voltage dependence of spin transport is theoretically investigated in a new type of magnetic tunnel junction, which consists of two ferromagnetic outer electrodes separated by a ferromagnetic barrier and a nonmagnetic (NM) metallic spacer. The effect of spin fluctuation in magnetic barrier, which plays an important role at finite temperature, is included by taking the mean-field approximation. It is found that, the tunnel magnetoresistance (TMR) and the electron-spin polarization depend strongly on the temperature and the applied voltage. The TMR and spin polarization at different temperatures show an oscillatory behavior as a function of the NM spacer thickness. Also, the amplitude of these oscillations is regularly reduced when the temperature increases. The maximum TMR value, varies approximately from 270% in reverse bias (at $T$=0 K) to 25% in forward bias (at $T\geq T_C$).

description: We performed calculations of the electronic band structure and the Fermi surface as well as measured the longitudinal resistivity rhoxx(T,H), Hall resistivity rhoxy(T,H) and quantum oscillations of the magnetization as a function of temperature at various magnetic fields for MoO2 with monoclinic crystal structure. The band structure calculations show that MoO2 is a nodal-line semimetal when spin-orbit coupling is ignored. It was found that a large magnetoresistance reaching 5.03x10^4% at 2 K and 9 T, its nearly quadratic field dependence and a field-induced up-turn behavior of rhoxx(T), the characteristics common for many topologically non-trivial as well as trivial semimetals, emerge also in MoO2. The observed properties are attributed to a perfect charge-carrier compensation, evidenced by both calculations relying on the Fermi surface topology and the Hall resistivity measurements. Both the observation of negative magnetoresistance for magnetic field along the current direction and the non-zero Berry phase in de Haas-van Alphen measurements indicate that pairs of Weyl points appear in MoO2, which may be due to the crystal symmetry breaking. These results highlight MoO2 as a new platform materials for studying the topological properties of oxides.

description: The U. S. biodiesel industry is rapidly expanding due to energy production concerns, environmental concerns, and recent legislation. The most common type of biodiesel in the United States is derived from soybean oil. Soybeans are a major crop in North Dakota and could easily supply a 5 million gallon per year biodiesel facility. Potential market segments of a biodiesel facility in North Dakota include agriculture, construction, and state fleet sectors based on current diesel use. However, with existing technology and no subsidy, biodiesel operation and investment costs for a North Dakota facility are not competitive with petroleum diesel. Using soybean oil prices of 17 cents to 25 cents per pound, the per gallon cost of producing diesel in southeastern North Dakota ranges between $2.02 and $2.64, while the wholesale price for regular diesel is $0.91. The cost of producing biodiesel is highly dependent on the price and availability of soybean oil. While biodiesel production technology is feasible and fairly simple, producing biodiesel in North Dakota is not economically feasible at least in the foreseeable future.

description: Obscurins are giant cytoskeletal proteins with structural and regulatory roles. Obscurin-B (~870 kDa), the largest known isoform, contains 2 enzymatically active Ser/Thr kinase (kin) domains, kin1 and kin2, which belong to the myosin light chain kinase family. Kin1 binds to and phosphorylates N-cadherin, a major component of the intercalated disc, the unique sarcolemmal microdomain that mediates the mechanochemical coupling of adjacent cardiomyocytes. Obscurin-B containing kin1 and N-cadherin colocalize at cell junctions in embryonic rat ventricular myocytes (ERVMs), and their codistribution is regulated by Ca2+. Phosphoproteomics analysis revealed that obscurin-kin1 phosphorylates N-cadherin at Ser-788 located within the juxtamembrane region of its cytoplasmic domain, with an apparent Kcat of approximately 5.05 min–1. Overexpression of obscurin-kin1 or phosphomimic-Ser-788-Glu N-cadherin in ERVMs markedly increases cell adhesion and chemical coupling. Importantly, phosphomimic Ser-788-Glu N-cadherin exhibits significantly reduced binding to p120-catenin, while overexpression of phosphoablated Ser-788-Ala N-cadherin increases RhoA activity. Consistent with an essential role of the obscurin-kin1/N-cadherin axis in cardiomyocyte coupling, it is deregulated in end-stage human heart failure. Given the nearly ubiquitous expression of obscurin and N-cadherin, our findings may have broad applicability in deciphering the obscurin-kin1/N-cadherin axis that likely mediates cell coupling in diverse tissues and organs.

description: We have attempted to establish an observational evidence for presence of distant companions which may have acquired and/or absorbed the angular momentum during evolution of multiple systems thus facilitating or enabling formation of contact binaries. In this preliminary investigation we use several techniques (some of them distance-independent) and mostly disregard detection biases of individual techniques in an attempt to establish a lower limit to the frequency of triple systems. While the whole sample of 151 contact binary stars brighter than Vmax = 10 mag. gives a firm lower limit of 42+/-5%, the corresponding number for the much better observed Northern-sky sub-sample is 59+/-8%. These estimates indicate that most contact binary stars exist in multiple systems.

description: The U.S. rice sector is expected to receive some of the largest relative support under the 2002 Farm Act. USDA's rice baseline model is used to compute marketing loan benefits, while direct payments and counter-cyclical payments are estimated from endogenous prices and exogenous policy parameters. Alternative scenarios of reduced marketing loan benefits suggest that projected annual average sector revenue could decline by 4 to 27 percent.

description: Hybrid offshore renewable energy platforms have been proposed to optimise power production and reduce the levelised cost of energy by integrating or co-locating several renewable technologies. One example is a hybrid wave-wind energy system that combines offshore wind turbines with wave energy converters (WECs) on a single floating foundation. The design of such systems involves multiple parameters and performance measures, making it a complex, multi-modal, and expensive optimisation problem. This paper proposes a novel, robust and effective multi-objective swarm optimisation method (DMOGWA) to provide a design solution that best compromises between maximising WEC power output and minimising the effect on wind turbine nacelle acceleration. The proposed method uses a chaotic adaptive search strategy with a dynamic archive of non-dominated solutions based on diversity to speed up the convergence rate and enhance the Pareto front quality. Furthermore, a modified exploitation technique (Discretisation Strategy) is proposed to handle the large damping and spring coefficient of the Power Take-off (PTO) search space. To evaluate the efficiency of the proposed method, we compare the DMOGWA with four well-known multi-objective swarm intelligence methods (MOPSO, MALO, MODA, and MOGWA) and four popular evolutionary multi-objective algorithms (NSGA-II, MOEA/D, SPEA-II, and PESA-II) based on four potential deployment sites on the South Coast of Australia. The optimisation results demonstrate the dominance of the DMOGWA compared with the other eight methods in terms of convergence speed and quality of solutions proposed. Furthermore, adjusting the hybrid wave-wind model’s parameters (WEC design and PTO parameters) using the proposed method (DMOGWA) leads to a considerably improved power output (average proximate boost of 138.5%) and a notable decline in wind turbine nacelle acceleration (41%) throughout the entire operational spectrum compared with the other methods. This improvement could lead to millions of dollars in additional income per year over the lifespan of hybrid offshore renewable energy platforms.

description: The interaction between off-resonant laser pulses and excitons in monolayer transition metal dichalcogenides is attracting increasing interest as a route for the valley-selective coherent control of the exciton properties. Here, we extend the classification of the known off-resonant phenomena by unveiling the impact of a strong THz field on the excitonic resonances of monolayer MoS$_2$. We observe that the THz pump pulse causes a selective modification of the coherence lifetime of the excitons, while keeping their oscillator strength and peak energy unchanged. We rationalize these results theoretically by invoking a hitherto unobserved manifestation of the Franz-Keldysh effect on an exciton resonance. As the modulation depth of the optical absorption reaches values as large as 0.05 dB/nm at room temperature, our findings open the way to the use of semiconducting transition metal dichalcogenides as compact and efficient platforms for high-speed electroabsorption devices.

We also prove that the Hodge volume of the moduli space is finite. Finally, we proved that the curvature of the Hodge metric is bounded if the Hodge metric is complete and the dimension of the moduli space is 1.

description: This paper develops a dynamic model of land, crop, and residue management choices in a typical Midwestern farm region. Carbon renting policy is implemented with alternative assumptions about relative crop prices. Model results show following results. First, crop choice between corn and soybean within a scenario does not appear to be sensitive to carbon prices. Second, residue management and carbon storage depend on crop prices and total carbon storage in soil is the greatest when more land is maintained in soybean. Third, there would be 4-7% increase in carbon per hectare with $3 per ton carbon price, 13-23% increase with $10 per ton carbon price, and 31-55% increase in carbon storage with $40 per ton carbon price.
Nonlinearly driven transverse synchronization in coupled chaotic systems

description: Synchronization transitions are investigated in coupled chaotic maps. Depending on the relative weight of linear versus nonlinear instability mechanisms associated to the single map two different scenarios for the transition may occur. When only two maps are considered we always find that the critical coupling $ε_l$ for chaotic synchronization can be predicted within a linear analysis by the vanishing of the transverse Lyapunov exponent $λ_T$. However, major differences between transitions driven by linear or nonlinear mechanisms are revealed by the dynamics of the transient toward the synchronized state. As a representative example of extended systems a one dimensional lattice of chaotic maps with power-law coupling is considered. In this high dimensional model finite amplitude instabilities may have a dramatic effect on the transition. For strong nonlinearities an exponential divergence of the synchronization times with the chain length can be observed above $ε_l$, notwithstanding the transverse dynamics is stable against infinitesimal perturbations at any instant. Therefore, the transition takes place at a coupling $ε_{nl}$ definitely larger than $ε_l$ and its origin is intrinsically nonlinear. The linearly driven transitions are continuous and can be described in terms of mean field results for non-equilibrium phase transitions with long range interactions. While the transitions dominated by nonlinear mechanisms appear to be discontinuous.

description: Being asked to comment on Chapter 8 of the Report, presented us with an awkward problem. It is, in a sense, difficult not to be unfair to the Group in any critical and in-depth review of the issues and options raised: or indeed, if a similar approach is taken to issues and options not raised in it. This is because, in its terms of reference, the Group was simply asked to 'identify major policy issues and options'. The Group does seem to have been more successful in identifying the policy issues than the options. We appreciate that it would be difficult in a short chapter to provide more than an annotated treatment of the many policy options which relate to transport, storage and handling of Australia's rural exports. This general observation has influenced our commentary. It is not as iconoclastic as it might have been in other circumstances. In our remarks we have opted to comment on the emphasis (or lack of it) given to the policy issues and options which have been raised in Chapter 8. Following that, we discuss a few of the key transport issues identified in the Report. Finally, we comment on a few issues which we think were either neglected or given less than adequate treatment.

description: We study an influence of the continuous measurement in a composite quantum system C on the evolution of the states of its parts. It is shown that the character of the evolution (decoherence or recoherence) depends on the type of the measured quantity and on the initial state of the system. A number of conditions under which the states of the subsystems of C decohere during the measuring process are established. We propose a model of the composite system and specify the observable the measurement of which may result in the recoherence of the state of one of the subsystems of C. In the framework of this model we find the optimal regime for the exchange of information between the parts of C during the measurement. The main characteristics of such a process are computed. We propose a scheme of detection of the recoherence under the measurement in a concrete physical experiment.

description: We present the analysis of 9.7 years Fermi-LAT data of the middle-aged supernova remnant W44 and the massive molecular gas complex that surrounds it. We derived a high-quality spectral energy distribution of gamma-radiation of the shell over three decades. The very hard spectrum below 1 GeV supports the earlier claims regarding the hadronic origin of radiation. We also confirm the presence of two extended $γ$-ray structures located at two opposite edges of the remnant along its major axis. Based on the high-resolution gas maps, we demonstrate that the gamma-ray structures are caused by the enhanced cosmic-ray density rather than the gradient of the gas distribution. We argue that the revealed cosmic-ray "clouds" suggest an anisotropic character of the escape of high-energy particles from the shell along the magnetic field of the remnant.

The mechanism is based on the mechanical effect of light. The degree of entanglement can be controlled through the parameters of the laser excitation.

A variation of the technique allows for controlled generation of entangled subsequent pulses, with the atomic motion serving as intermediate memory of the quantum state.

description: This study proposes a new prairie dog optimization algorithm version called EPDO. This new version aims to address the issues of premature convergence and slow convergence that were observed in the original PDO algorithm. To improve performance, several modifications are introduced in EPDO. First, a dynamic opposite learning strategy is employed to increase the diversity of the population and prevent premature convergence. This strategy helps the algorithm avoid falling into local optima and promotes global optimization. Additionally, the Lévy dynamic random walk technique is utilized in EPDO. This modified Lévy flight with random walk reduces the algorithm’s running time for the test function’s ideal value, accelerating its convergence. The proposed approach is evaluated using 33 benchmark problems from CEC 2017 and compared against seven other comparative techniques: GWO, MFO, ALO, WOA, DA, SCA, and RSA. Numerical results demonstrate that EPDO produces good outcomes and performs well in solving benchmark problems. To further validate the results and assess reliability, the authors employ average rank tests, the measurement of alternatives, and ranking according to the compromise solution (MARCOS) method, as well as a convergence report of EPDO and other algorithms. Furthermore, the effectiveness of the EPDO algorithm is demonstrated by applying it to five design problems. The results indicate that EPDO achieves impressive outcomes and proves its capability to address practical issues. The algorithm performs well in solving benchmark and practical design problems, as supported by the numerical results and validation methods used in the study.

description: Excerpts from the report Foreword: This report summarizes results of an effort to establish a consumer panel by following probability sampling procedures. The effort was undertaken by the Market Research Corporation of America (formerly Industrial Surveys Company) as a part of a contract under the Agricultural Marketing Act of 1946 (RMA, Title II). This Act authorizes the collection and dissemination of marketing information "for the purpose of anticipating and meeting consumer requirements, aiding in the maintenance of farm income and bringing about a balance between production and utilization of agricultural products." The term "consumer panel" refers to a sample of households that maintain records of their day-to-day purchases of many specified items and report by mail each week. Such a panel has been maintained on the basis of quota sampling by the contractor since 1942.

description: The concept of effective temperatures in nonequilibrium systems is studied within an exactly solvable model of non-Markovian diffusion. The system is coupled to two heat baths which are kept at different temperatures: one ('fast') bath associated with an uncorrelated Gaussian noise and a second ('slow') bath with an exponential memory kernel. Various definitions of effective temperatures proposed in the literature are evaluated and compared. The range of validity of these definitions is discussed. It is shown in particular, that the effective temperature defined from the fluctuation-dissipation relation mirrors the temperature of the slow bath in parameter regions corresponding to a separation of time scales. On the contrary, quasi-static and thermodynamic definitions of an effective temperature are found to display the temperature of the fast bath in most parameter regions.

description: In September 1981, the then Minister for Primary Industry set up a Working Group under the Chairmanship of Sir James Balderstone to prepare, within one year, a policy discussion paper on agriculture. The terms of reference were wide-ranging and included the need to identify the major policy issues and options relating to the agricultural sector. The relevant time horizon was taken to be the 1980s. The terms of reference were: (a) intersectoral relationships affecting agriculture, including resource development, wages policy and assistance to other sectors; (b) trade policy, in particular the impact of the Common Agriculture Policy of the EEC; (c) factors affecting technical and economic efficiency in agriculture; (d) current government assistance to agriculture, including the financial aspects of rural credit and taxation; (e) the marketing of farm products, including the role of statutory bodies; (f) agricultural resource management, including soil and water conservation; and (g) 'animal husbandry measures' which the Group interpreted as covering some of the problems of the intensive livestock industries and live sheep exports which have attracted the concern of some animal liberation and welfare movements. It would be impossible to discuss all of the terms of reference in detail in this overview. What I propose to do is to raise some of the conceptual and philosophical issues which might be reflected in the Report and then to discuss some of the specific policy recommendations which might provide a basis for more detailed discussion. It is important to emphasise that the Group's instructions were to provide a discussion paper and not to come up with a White Paper (in the old terminology) which might have been construed as actual government policy with respect to the rural sector.

description: The use of cell secreted factors in clinical settings could be an alternative to conventional cell therapy, with the advantage of limiting concerns generally associated with traditional cell transplantation, such as tumorigenicity, immunoreactivity, and carrying of infections. Based on our published data, we predict a potential role for extracellular vesicles (EVs) in contributing to the proangiogenic activity of human fetal dermal cell secretome. Depletion of nanosized EVs from secretome significantly impaired its ability to induce formation of mesh-like structures in vitro. The isolated EVs were characterized for size and concentration by nanoparticle tracking analysis, and for protein markers (Rab5+, Alix+, CD63+, and calnexin-). The microRNA profile of EVs revealed 87 microRNAs significantly upregulated (≥15-fold increase) in fetal compared to adult dermal cell-derived EVs. Interestingly, these upregulated microRNAs included microRNAs with a validated role in angiogenesis according to literature. Moreover, the DIANA-TarBase v7.0 analysis confirmed enrichment in the KEGG signaling pathways associated with angiogenesis and wound healing, with the identification of putative target genes including thrombospondin 1. To validate the in silico data, EVs were also characterized for total protein contents. When tested in in vitro angiogenesis, fetal dermal cell-derived EVs were more effective than their adult counterpart in inducing formation of complete mesh-like structures. Furthermore, treatment of fibroblasts with fetal dermal-derived EVs determined a 4-fold increase of thrombospondin 1 protein amounts compared with the untreated fibroblasts. Finally, visualization of CSFE-labeled EVs in the cytosol of target cells suggested a successful uptake of these particles at 4-8 hours of incubation. We conclude that EVs are important contributors of the proangiogenic effect of fetal dermal cell secretome. Hence, EVs could also serve as vehicle for a successful delivery of microRNAs or other molecules of therapeutic interest to target cells.

description: BackgroundMaternity waiting homes are used to enhance women's access to health facilities in low-resource settings; however, its use remains low in Ethiopia. It is important to investigate strategies that can enhance the usage of maternity waiting homes in Ethiopia.MethodsThe purpose of his study is to assess how well couple-focused health education works to increase maternal knowledge, attitudes, and use of maternity waiting homes in rural Ethiopia. A cluster-randomized trial with two parallel groups will be the study's design. Three hundred twenty samples will be drawn from 16 clusters (160 in each group). Clusters will be assigned to intervention or control groups using a restricted randomization with a 1:1 allocation ratio. Women who are in their 14–16 weeks of gestation, or in the early stages of their second trimester, along with their male partners, will participate in the study. Health education, home visits, and the distribution of leaflets will be the intervention packages.DiscussionThe trial results will provide conclusive evidence on whether couple-based health education can improve women's access to maternity waiting homes in rural Ethiopia.

description: In principle, the Group regards long-run market forces as the best guide to resource allocation, not only within existing production units, but also between sectors. However, in practice they perceive many instances of market failure in the rural sector which justify government intervention either on efficiency grounds or on equity grounds. They aggregate these intervention/assistance measures into sets and devote a chapter to each set. The new, novel and controversial aspects of assistance are highlighted in these comments. The Group discussed price support and underwriting schemes, input subsidies and related issues, natural disaster relief, income tax averaging, product promotion and export inspection services in Chapter 5 and research, extension and education in the context of innovation in Chapter 9.

description: The Report commenced, appropriately, by addressing the federal contract within which Australian agricultural policy is set. The Australian Constitution limits what can be done by the Commonwealth and State Governments and establishes procedures for settling arguments about where jurisdictions lie. There is a wider constitutional framework than the Constitution itself. It includes, for example, the Australian Agricultural Council which is the major means of co-ordinating powers and resolving conflicts between the Commonwealth and states in the field of agricultural policy. The federal contract also includes the wide range of co-operative approaches to policy, such as statutory marketing intitutions and the complementary legislation which supports them. The issue of federalism runs through the whole of the Report, but only in Chapter 2 was it addressed as a central issue. The Group viewed the Constitution itself as virtually immutable. The Australian Agricultural Council was criticised for acting only slowly and by consensus. Where there is a fundamental conflict of interest, the Commonwealth's financial strength may need to be used to encourage state co-operation. The emergence of the National Farmers' Federation was seen as hopeful, and there was a hint that a formal link between the Council and the Federation could facilitate consensus. But, on the whole, the tone of the Report regarding the federal contract was not enthusiastic. It was seen to constrain opportunities for change rather than to create them. Issues for the 1980s with respect to inter-governmental relations were expected to be similar to those of the past. In Chapter 2, the Group provided a brief synopsis of the respective roles of the Commonwealth and State Governments in areas covered in the rest of the Report, namely, assistance, marketing, international trade, transport, innovation and resource management. But having set the scene with an overview of the constitutional framework, the Group did not return to a federal overview of policy options. It is with that important task in view that I will address briefly three of the issues raised in Chapter 2, namely, assistance, marketing and international trade, and comment on Commonwealth grants to the states which are relevant to the remaining issues. My purpose is to highlight some policy dilemmas which need to be resolved within a federal context.

The effect of uncertainties on chemical models of dark clouds

description: The gas-phase chemistry of dark clouds has been studied with a treatment of uncertainties caused both by errors in individual rate coefficients and uncertainties in physical conditions. Moreover, a sensitivity analysis has been employed to attempt to determine which reactions are most important in the chemistry of individual species. The degree of overlap between calculated errors in abundances and estimated observational errors has been used as an initial criterion for the goodness of the model and the determination of a best 'chemical' age of the source. For the well-studied sources L134N and TMC-1CP, best agreement is achieved at so-called "early times" ~10$^{5}$ yr, in agreement with previous calculations but here put on a firmer statistical foundation. A more detailed criterion for agreement, which takes into account the degree of disagreement, is also proposed. Poorly understood but critical classes of reactions are delineated, especially reactions between ions and polar neutrals. Such reactions will have to be understood better before the chemistry can be made more secure. Nevertheless, the level of agreement is low enough to indicate that a static picture of physical conditions without consideration of interactions with grain surfaces is inappropriate for a complete understanding of the chemistry.

description: Mortality related to melanoma cancer has increased in recent years, mainly due to new habits of sun exposure. Considering the medical criteria, early diagnosis has become the best method of prevention but this is not trivial because experts are facing a problem characterized by a large volume of data, heterogeneous, and with partial knowledge. Based on these requirements we propose the creation of a decision support system that is able to assist experts in melanoma diagnosis. The system has to cope with various challenges, that include the characterization of the domain, the identification of data patterns attending to medical criteria, the classification of new patients, and the ability to explain predictions. These goals have been materialized in DERMA platform that is based on the collaboration of several analogical reasoning multi-label subsystems. The experiments conducted with the proposed system using confocal and dermoscopic images data have been allowed to ascertain the reliability of the system. The results have been validated by experts in diagnosis of melanoma considering it as positive.
Seismic response of diagonally reinforced slender coupling beams

description: The seismic response of diagonally reinforced slender coupling beams is investigated. Primarily, a typical coupling beam found in high-rise buildings in the Vancouver area is studied. Compared to past experiments, this study takes into account a new variable, the axial restraint given by the concrete slab surrounding the coupling beam. Desirable and ductile properties of the beam are studied throughout this work, such as ductility capacity, stiffness degradation, overstrength and energy dissipation capability. A finite element analysis was performed to study the axial restraint parameter mentioned above and assess the degree of restraint given by the slab to the coupling beam. Parameters such as the slab dimensions, slab pre-cracking, slab thickness, mesh size of the model and tension stiffening model are considered. This analysis indicated that the tension stiffening model used for the concrete is the most important parameter. A full-scale coupling beam specimen was tested to develop an analytical model and compare the results with well-known formulas recommended by various Codes. The specimen represented a typical coupling beam found in high-rise buildings in the Vancouver area. The specimen was subjected to cyclic loading and Dywidag bars were provided to model the slab axial restraint. The results showed higher overstrength and stiffness degradation factors than the ones expected from well-known formulas. As expected for diagonally reinforced coupling beams, the specimen showed good ductility and energy dissipation properties. An analytical model based on a truss structure was developed to better understand the behaviour of diagonally reinforced coupling beams. The model gave insight to main factors of the problem, such as diagonal reinforcement, geometry, concrete considered and slab restraint. The monotonic prediction of the model was reasonably similar to the envelope given by the experimental results. Expressions were developed from this model to predict the cracked stiffness and overstrength factor.
