Equivalent elastic modulus for prediction of deformations in joints

When studying human joints contact mechanics, surface deformations are relevant as they enable a lubrication flow channel that reduces wear. In order to determine the validity of different methods to predict surface displacements, these were applied to the dry and static contact of healthy and prosthetic joints, both for knee and hip joints. Three equivalent elastic modulus for a simplified column model were evaluated: elastic modulus for a layer solid, elastic modulus for a semi-infinite solid (or Winkler elastic modulus) and elastic modulus for a corrected semi-infinite solid. A hertzian load was considered for all cases. The results were compared with the solution of the elasticity equations by means of the finite element method (FEM). The results for the Young ́s modulus, corresponding to a material as a layer, are those that best approximate the FEM prediction. It is also shown that the Young ́s module derived from the semi-infinite approximation are inappropriate. Likewise, this work allowed the training of an undergraduate student in Computational Mechanics. En el estudio de la mecánica de contacto de las articulaciones humanas, la deformación de las superficies en contacto es fundamental porque posibilita un canal por el que fluye el lubricante reduciendo el desgaste. Para determinar la validez de las predicciones de los desplazamientos de estas superficies a partir de distintos métodos, estos se aplican al estudio del contacto seco y estático de articulaciones de rodilla y de cadera, sanas y protésicas. Aplicando una carga hertziana, se evaluaron tres módulos elásticos equivalentes en un modelo simplificado de columna: el correspondiente a un sólido de pequeño espesor, el correspondiente a un sólido semiinfinito o de Winkler y el correspondiente a un sólido semiinfinito corregido. Los resultados se contrastaron con la solución obtenida resolviendo numéricamente las ecuaciones de elasticidad mediante el método de elementos finitos (MEF). Los resultados para el módulo de Young correspondiente a un material de pequeño espesor, son los que mejor se aproximan a los obtenidos por el MEF. Se demuestra también, que los módulos de Young derivados de la aproximación de sólido semiinfinito son inapropiados. Asimismo, con este trabajo se ha entrenado un becario en las artes de la Mecánica Computacional.
Creative AI: a New Avenue for Semantic Web?

Computational Creativity (or artiﬁcial creativity) is a multidisciplinary ﬁeld, researching how to construct computer programs that model, simulate, exhibit or enhance creative behaviour. This vision paper explores a possible impact Semantic Web can have on the future of creativity, especially when it deals with AI creativity. Possible uses of Semantic Web and semantic technologies are discussed, regarding three types of creativity: i) exploratory creativity, ii) combinational creativity, and iii) transformational creativity and relevant research questions. For exploratory creativity, how can we explore the limits of what is possible, while remaining bound by a set of existing domain axioms, templates, and rules, expressed with semantic technologies? To achieve a combinational creativity, how can we combine or blend existing concepts, frames, ontology design patterns, and other constructs, and beneﬁt from cross-fertilization? Ultimately, can we use ontologies and knowledge graphs, which describe an existing domain with its constraints and, applying a meta-rule for transformational creativity, start dropping constraints and adding new constraints and see what emerges? Together with these new challenges, the paper also provides pointers to emerging and growing application domains of Semantic Web and knowledge graphs related to computational creativity and design: from food and cooking (recipe generation), fashion and style to program synthesis
Late Sequelae of Acute Deep Venous Thrombosis: Evaluation Five and Ten Years after

Objective: To study the sequelae of an acute deep venous thrombosis (DVT) 5 or 10 years afterwards. Design: A retrospective questionnaire study involving 70 patients with DVT, verified by phlebography 5 and 10 years earlier. Setting: Tampere University Hospital, Finland. Patients: Seventy out of 86 patients who had suffered a definite DVT answered a questionnaire on subjective symptoms and visits to health care organizations. Interventions: All 70 patients were treated initially with heparin and warfarin after the DVT was diagnosed. Main outcome measures: The frequency of late symptoms in the leg with DVT. The relation of the site of the acute DVT to late sequelae. Results: The frequency of asymptomatic patients was only 13%. Typical symptoms were evening pain, oedema and pigmentation. There were no differences between calf DVTs and more proximal DVTs in respect of the late symptoms. All patients with recurrent DVT were symptomatic. Conclusions: The late sequelae of DVT are common and necessitate a considerable number of visits to health care centres. Calf DVTs seem to cause late symptoms as often as more proximal DVTs.
Composing schema mappings: Second-order dependencies to the rescue

A schema mapping is a specification that describes how data structured under one schema (the source schema) is to be transformed into data structured under a different schema (the target schema). A fundamental problem is composing schema mappings: given two successive schema mappings, derive a schema mapping between the source schema of the first and the target schema of the second that has the same effect as applying successively the two schema mappings.In this article, we give a rigorous semantics to the composition of schema mappings and investigate the definability and computational complexity of the composition of two schema mappings. We first study the important case of schema mappings in which the specification is given by a finite set of source-to-target tuple-generating dependencies (source-to-target tgds). We show that the composition of a finite set of full source-to-target tgds with a finite set of tgds is always definable by a finite set of source-to-target tgds, but the composition of a finite set of source-to-target tgds with a finite set of full source-to-target tgds may not be definable by any set (finite or infinite) of source-to-target tgds; furthermore, it may not be definable by any formula of least fixed-point logic, and the associated composition query may be NP-complete. After this, we introduce a class of existential second-order formulas with function symbols and equalities, which we call second-order tgds, and make a case that they are the “right” language for composing schema mappings. Specifically, we show that second-order tgds form the smallest class (up to logical equivalence) that contains every source-to-target tgd and is closed under conjunction and composition. Allowing equalities in second-order tgds turns out to be of the essence, even though the “obvious” way to define second-order tgds does not require equalities. We show that second-order tgds without equalities are not sufficiently expressive to define the composition of finite sets of source-to-target tgds. Finally, we show that second-order tgds possess good properties for data exchange and query answering: the chase procedure can be extended to second-order tgds so that it produces polynomial-time computable universal solutions in data exchange settings specified by second-order tgds.
Lightweight remote procedure call

Lightweight Remote Procedure Call (LRPC) is a communication facility designed and optimized for communication between protection domains on the same machine. In contemporary small-kernel operating systems, existing RPC systems incur an unnecessarily high cost when used for the type of communication that predominates — between protection domains on the same machine. This cost leads system designers to coalesce weakly-related subsystems into the same protection domain, trading safety for performance. By reducing the overhead of same-machine communication, LRPC encourages both safety and performance. LRPC combines the control transfer and communication model of capability systems with the programming semantics and large-grained protection model of RPC. LRPC achieves a factor of three performance improvement over more traditional approaches based on independent threads exchanging messages, reducing the cost of same-machine communication to nearly the lower bound imposed by conventional hardware. LRPC has been integrated into the Taos operating system of the DEC SRC Firefly multiprocessor workstation.
DSD-Crasher: a hybrid analysis tool for bug finding

DSD-Crasher is a bug finding tool that follows a three-step approach to program analysis: D. Capture the program's intended execution behavior with dynamic invariant detection. The derived invariants exclude many unwanted values from the program's input domain. S. Statically analyze the program within the restricted input domain to explore many paths. D. Automatically generate test cases that focus on verifying the results of the static analysis. Thereby confirmed results are never false positives, as opposed to the high false positive rate inherent in conservative static analysis.This three-step approach yields benefits compared to past two-step combinations in the literature. In our evaluation with third-party applications, we demonstrate higher precision over tools that lack a dynamic step and higher efficiency over tools that lack a static step.
3D DIGITIZATION AND VIRTUAL RESTORATION OF CERAMIC SHERDS

Excavations reveal greatly preserved artifacts but highly fragmented artifacts as well. When preserved artifacts are discovered not very time consuming post-excavation work will be required. In contrast when hundreds of sherds are discovered, tremendous amount of work may follow to reconstruct the artifacts. This work is usually not done due to budgetary constraints and the sherds are stored for several years in warehouses. In this work, we propose a framework to accommodate the automated assembly of the sherds and evaluate the performance of two algorithms that can be the backbone of automated assembly. The performance evaluation experiments are done on three different sets of sherds that serve as the ground truth.
Microbial Synthesis and Characterization of Biodegradable Polyester Copolymers from Burkholderia Cepacia and Cupriavidus Necator Strains Using Crude Glycerol as Substrate

Polymers are materials of pronounced importance in the modern world, since they are massively present in everyday life, especially in the form of packaging. However, most of these materials are derived from non-renewable sources and their disposal generates large volumes of waste, which is extremely damaging to natural environments. In this context, microbial biopolymers appear as a powerful alternative in the substitution of several applications of synthetic plastics, causing less harm to the environment, as they are HIGHLIGHTS • PHAs copolymers were produced from crude glycerol by B. cepacia and C.

The Circular Relationship Between Productivity Growth and Real Interest Rates

In most advanced economies, both real interest rates and productivity growth have decreased since the early 1990s. In this paper, we explore the mechanism whereby a circular relationship links these two quantities. While productivity is a key driver of potential output which affects the level of interest rates, the level of interest rates is a determinant of the expected return from investment projects, and thus of the productivity level required for investment. In our model, absent of a technology shock, this specific relationship can only converge to an equilibrium where growth and interest rates are both low. We test this using macroeconomic data on 17 OECD countries and simulate the effect of a temporary productivity shock.
Limited Participation, Capital Accumulation and Optimal Monetary Policy

Motivated by recent empirical findings on money demand, the paper presents a general equilibrium model where agents have limited participation in financial markets and use money to smooth consumption. In such setup, investment is not optimal because only a fraction of households participate in financial markets in each period. Optimal monetary policy substantially increases welfare by changing investment decisions over the business cycle, but adverse redistributive effects limit the scope for an active monetary policy. Recent developments in the heterogeneous-agents literature are used to develop a tractable framework with aggregate shocks, where optimal monetary policy can be analyzed.
EVALUATION OF ANTIDIABETIC,ANTIHYPERLIPIDEMIC AND ANTIOXIDANT ACTIVITIES OF THE METHANOLIC EXTRACT OF Bauhinia variegata AND Enterolobium cyclocarpum LEAVES IN STREPTOZOTOCIN DIABETIC RATS

Hypoglycemic action of methanolic extracts of Bauhinia variegata and Enterolobium cyclocarpum leaves were studied on streptozotocin diabetic rats . Two different doses(200 and 400 mg/kg body weight)of the extracts were given orally to the rats for 22 days. Lipid profile improvement and hepatoprotective effects against liver disorders associated with diabetic complications were also studied . Results revealed that Bauhinia variegata extract showed a strong antidiabetic activity at the two doses. The doses of 400mg/kg b.wt. showed the highest activity . Enterolobium cyclocarpum extract at the two doses failed to decrease blood glucose level to the healthy range. The mode of Hypoglycemic action of Bauhinia variegata extract may due to the presence of considerable amounts of Flavonoids and polyphenols. The two extracts (Bauhinia variegata and Enterolobium cyclocarpum) could improve lipid profile of diabetic rats and Enterolobium cyclocarpum had weaker ability. Bauhinia variegata methanolic extract resulted in significant decrease in liver malondialdehyde (MDA)and increase in reduced glutathione (GSH) .

This study was conducted to determine the sero-prevalence of foot and mouth disease (FMD) in buffaloes (Bubalus bubalis) slaughtered at Islamabad slaughterhouse, Pakistan. Sera and oro-pharyngeal (OP) fluid were collected from 630 healthy buffaloes. These animals originated from various livestock markets from 14 districts of Punjab. The age of animals ranged from 1 to 15 years. Sera were analyzed using FMD virus (FMDV) nonstructural proteins (NSP) and indirect ELISA. The sero-prevalence of FMD was 47.1% (n=297). There was a strong association between age of animal and its risk of being positive for FMD NSP ELISA (Odds ratio 1.27; p<0.001; CI 1.22–1.32). The OP fluids were tested for the presence of FMDV by real time PCR. FMDV specific signals were detected in 33 samples (11.1%). Virus recovery attempts were made after treating them with tri-chloro-tri-flouroethane onto LFBK cell line and four FMD isolates were recovered. This study indicated high sero-prevalence of FMDV in buffaloes slaughtered at abattoir in Islamabad. Furthermore, the virus recovery from these animals is suggestive of their possible role in persistence and transmission of FMDV to other animals.
Efficiency of 1.5- to 4.5-keV x-ray production from laser plasmas

Laser to X-ray conversion efficiencies in the 1.5 - 4.5 keV photon energy range from solid targets irradiated by 2 ps duration KrF laser pulses of wavelength 248 nm and irradiance up to 2 x 1016 Wcm-2 have been measured. Unusually, a CCD camera working in single photon counting mode has been used to record the emitted spectra with moderate (λ/Δλ ≈ 50) spectral resolution. Efficiencies in converting laser energy to X-ray emission into 2π steradian are in the range 10-3 to 10-6 respectively for photon energies from 1.5 to 4.5 keV.

Representation of Women with Disabilities in Hindi Cinema

Women with disabilities are being discriminated in socio-economic and political partic ipation in India. A woman with disability is doubly discriminated. Their right to have sex and reproduction has been grossly denied, indicating human rights violations. Their social and economic participation is grossly undermined. In this context, the role of Hindi popular c inema is of paramount importance to address their issues. Hindi cinema, popularly known as Bollywood, is one of the biggest filmindustriesin the world. Many of the Hindi popular cinemas are being globally consumed. This study attempted to identify the nature of representation of women with disabilities in Bollywood from Koshish to Margarita with a Straw. The study covered the aspects of models of disability, socio-economic participation, andright to sex and reproduction while analyzing the films.
E-Cigarette Use, Perceptions, and Cigarette Smoking Intentions in a Community Sample of Young Adult Non-Daily Cigarette Smokers

E-cigarettes have been suggested as a strategy for reducing harm from cigarettes. While ecigarettes could be a less-harmful alternative to cigarettes for those trying to quit, there may also be costs that outweigh any benefits of reduction. The purpose of the present study was to prospectively investigate perceptions of e-cigarettes, cigarette smoking intentions and their associations with e-cigarette use over time. Community participants (n = 348, 57% male) aged 18– 24 were recruited for a longitudinal study of tobacco use. Inclusion criteria included non-daily cigarette smoking for ≥ 6 months with no history of daily smoking. Participants reported ecigarette use over the past 14 days at baseline and for the past 9 days at 3, 6, and 9 months. Assessments were completed online or via mobile phone. Across the 4 assessments, 22–33% of participants reported recent e-cigarette use. Intent to quit smoking cigarettes and intent to maintain smoking were unrelated to e-cigarette frequency. E-cigarette frequency was positively associated with perceiving e-cigarettes as less harmful than cigarettes and more positive e-cigarette expectancies (ps < .05). E-cigarette use was also more frequent among those who smoked cigarettes frequently and who used e-cigarettes to circumvent cigarette bans more often (ps < .05). The combination of these findings suggests that, at least among non-daily smoking young adults, other factors may influence frequency of e-cigarette use more than harm reduction. Findings instead seem consistent with the hypothesis that e-cigarettes are more often used to complement ongoing cigarette smoking.
Superstring measures in genus 5

By comparing expressions for degenerated curves, we show that combining two semi-modular forms from the two different ansätze for the chiral superstring measure in genus 5 yields a form that is not contained in either ansatz. We use this form to construct a modified ansatz for genus 5. By calculating the resulting two-point function for genus 4 and the cosmological constant in genus 5 we show that for our modified ansatz, both of them vanish as required. Thus, we solve the problem posed in [1]. Last, we show that from the currently known forms we cannot construct an ansatz for genus 6 that satisfies all requirements.

Anti-Oxidative and Anti-Inflammatory Activity of Kenya Grade AA Green Coffee Bean Extracts

Background: Kenya AA green coffee bean extracts were tested for natural ingredients used for anti-oxidative and anti-inflammatory purposes in cosmetic products. Methods: Anti-oxidative activities were measured by total polyphenol, 1,1-diphenyl-2-picrylhydrazyl (DPPH), and the 2,2′-azinobis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS) assays. Anti-inflammatory activities were evaluated via nitric oxide (NO) assays, and through quantification of inducible nitric oxide synthase (iNOS), and cyclooxygenase-2 (COX-2) protein expression by western blotting. Data analyses were performed using independent Student’s t-tests, with statistical significance set at P < 0.05. Results: Total polyphenol content of water and ethanol extract was 169.0 ± 3.1 mg and 300.34 ± 16.6 mg tannic acid/g dry weight, respectively. The DPPH and ABTS radical scavenging activities of all the extracts were significantly increased in a concentration-dependent manner. Kenya AA green coffee bean extracts were toxic at a concentration of 1,000 μg/mL in RAW 264.7 cells. Anti-inflammatory activity as determined by NO assay showed that lipopolysaccharide (LPS)-induced NO was significantly inhibited following treatment with Kenya AA green coffee bean extracts in a concentration-dependent manner. iNOS and COX-2 protein expression was also significantly inhibited following treatment. Conclusion: These results highlight the potential of Kenya AA green coffee bean extracts as a naturally active anti-inflammatory agent in cosmetic products.
