Two-dimensional analysis of gait asymmetry in spastic hemiplegia
Marise Bueno Zonta,Amancio Ramalho Júnior,Regina Maria Ribeiro Camargo,Fabiano Hessel Dias
Einstein (S?o Paulo) , 2010,
Abstract: Objective: Simple measures of gait for routine clinical use could be useful when the complex gait analysis systems are not available. The aim of this study was to quantify asymmetry in children with spastic hemiplegia using a two-dimensional gait analysis by videography and to relate the asymmetry to motor function. Methods: Twenty-four children with spastic hemiplegia (19 males, 5 females; mean age 49 months [SD 5 months], range from 39 to 60 months) were assessed with a two-dimensional gait analysis by videography and the analyzed parameters were compared with normal values and with clinical and functional data. Results: There were significant differences in swing time (p = 0.002), stance time (p = 0.01) and stance/swing time ratio (p < 0.001). The comparison with the normal values described by Sutherland also demonstrated gait asymmetry. There was no direct relationship between the motor function and asymmetry but a score analysis for specific Gross Motor Function Measure items could quantify it in terms of age of gait acquisition. Children with more adequate muscle tone presented longer stance time in the involved limb than those with more spasticity (p = 0.03). Conclusions: These results suggest that the best performance is associated with the smallest asymmetry in this sample. Although two-dimensional gait analysis does not provide as much data as three dimensional gait analyses, we believe it can contribute significantly to the gait assessment of children with cerebral palsy.
Exploring NoC Mapping Strategies: An Energy and Timing Aware Technique
Cesar Marcon,Ney Calazans,Fernando Moraes,Altamiro Susin,Igor Reis,Fabiano Hessel
Computer Science , 2007,
Abstract: Complex applications implemented as Systems on Chip (SoCs) demand extensive use of system level modeling and validation. Their implementation gathers a large number of complex IP cores and advanced interconnection schemes, such as hierarchical bus architectures or networks on chip (NoCs). Modeling applications involves capturing its computation and communication characteristics. Previously proposed communication weighted models (CWM) consider only the application communication aspects. This work proposes a communication dependence and computation model (CDCM) that can simultaneously consider both aspects of an application. It presents a solution to the problem of mapping applications on regular NoCs while considering execution time and energy consumption. The use of CDCM is shown to provide estimated average reductions of 40% in execution time, and 20% in energy consumption, for current technologies.
Pricing Options on Foreign Currency with a Preset Exchange Rate  [PDF]
Avner Wolf, Christopher Hessel
Journal of Mathematical Finance (JMF) , 2012, DOI: 10.4236/jmf.2012.23024
Abstract: This paper presents a new option that can be used by agents for managing foreign exchange risk. Unlike the Garman Kolhagen model [1], (GK), this paper presents a new model with a preset exchange rate (PE), that allows the agent to take advantage of the his/her view on both the direction and magnitude of rate movement and as such provides this agent with more choices. The model has a provision for an automatic exchange of the payoff at a preset exchange rate, and upon expiration gives the agent the choice of keeping the payoff in the foreign currency or exchanging it back to the pricing currency. At the time of writing, the buyer selects the preset exchange rate. Depending on the value selected, the PE option’s price and payoff will be equal to, greater than or less than those of the GK model. A decision rule for choosing between the PE and GK models is developed by determining the expiration spot rate that equates the two models’ returns. The range of spot rates that makes the PE option’s return greater than the GK’s return is the PE preferred range. If the agent expects the expiration spot rate will be within the preferred range, the PE option is purchased. The size of the preferred range is a decreasing function of time to expiration, a decreasing function of spot rate volatility and an increasing function of the basis point spread between foreign and domestic interest rates.
European integration and the supervision of local and regional authorities Experiences in the Netherlands with requirements of European Community law
Bart Hessel
Utrecht Law Review , 2006,
Abstract: As a result of increasing European integration, local and regional authorities are having to deal with European law more and more intensively. As Member States (read: central government) are responsible vis-à-vis the Community for the errors of local and regional authorities, the question arises within Member States whether the central government possesses sufficient supervisory instruments for complying with their obligations under Community law: they must ensure that the errors of local and regional authorities are rectified in time, and national law must provide for sufficient possibilities to do so. Although Community law is neutral towards the internal relations between the various tiers of government within the Member States, this responsibility of the central government may, as a result of European integration, lead to a need for more powerful supervisory instruments in relation to local and regional authorities. In the past five years there has been some debate on this subject within the Netherlands and after a long delay the Dutch cabinet in 2004 decided that the existing supervisory instruments in the decentralized unitary state of the Netherlands should be expanded. The legislation intended to realize this expansion is being prepared. This discussion and its results would seem of interest to other Member States of the Community facing similar problems.
The Heisenberg group and conformal field theory
Hessel Posthuma
Physics , 2007,
Abstract: A mathematical construction of the conformal field theory (CFT) associated to a compact torus, also called the "nonlinear Sigma-model" or "lattice-CFT", is given. Underlying this approach to CFT is a unitary modular functor, the construction of which follows from a "Quantization commutes with reduction"- type of theorem for unitary quantizations of the moduli spaces of holomorphic torus-bundles and actions of loop groups. This theorem in turn is a consequence of general constructions in the category of affine symplectic manifolds and their associated generalized Heisenberg groups.

Brazilian Journal of Infectious Diseases , 2008, DOI: 10.1590/S1413-86702008000500008
Abstract: invasive aspergillosis (ia) currently is an important cause of mortality in subjects undergoing hematopoietic stem cell transplants (hsct) and is also an important cause of opportunistic respiratory and disseminated infections in other types of immunocompromised patients. we examined the medical records of 24 cases of proven and probable invasive aspergillosis (ia) at the hospital de clinicas of the federal university of parana, brazil, from january 1996 to october 2006. during this period occurred a mean of 2.2 cases per year or 3.0 cases per 100 hstc transplants. there was a significant relationship between structural changes in the bone marrow transplant (bmt) unit and the occurrence of ia cases (p=0.034, relative risk (rr) = 2.47). approximately 83% of the patients died due to invasive fungal infection within 60 days of follow up. some factors tended to be associated with mortality, but these associations were not significant. these included corticosteroid use, neutropenia (<100 cells/mm3) at diagnosis, patients that needed to change antifungal therapy because of toxicity of the initial first-line regimen and disseminated disease. these factors should be monitored in bmt units to help prevent ia. physicians should be aware of the risk factors for developing invasive fungal infections and try to reduce or eliminate them. however, once this invasive disease begins, appropriate diagnostic and treatment measures must be implemented as soon as possible in order to prevent the high mortality rates associated with this condition.

Revista Brasileira de Zootecnia , 2001,
Abstract: Utilizaram-se 70 bovinos machos de três sistemas de acasalamento, puros Charolês (Ch) e Nelore (Ne), mesti os G1: 1/2 Ch + 1/2 Ne (1/2 Ch) e 1/2 Ne + 1/2 Ch (1/2 Ne) e mesti os G2: 3/4 Ch + 1/4 Ne (3/4 Ch) e 3/4 Ne + 1/4 Ch (3/4 Ne). O número de animais por grupo genético foi, respectivamente, 15, 12, 8, 12, 14 e 9. Trinta e cinco animais foram castrados (C) aos sete meses e 35 foram mantidos inteiros (I). Os animais foram confinados dos 20 aos 24 meses, quando foram abatidos. Para avalia o da carne, foi utilizado o músculo longissimus dorsi. N o houve intera o significativa entre grupo genético e estado sexual para nenhuma das variáveis estudadas. Os machos I apresentaram carne mais escura (3,05 contra 3,78 pontos) com menor marmoreio (4,26 contra 5,75 pontos) e menos extrato etéreo (1,73 contra 2,88%). Entretanto, a área de longissimus dorsi foi maior (66,03 contra 60,50 cm2) e a carne com melhor palatabilidade, suculência e mais macia. Na compara o entre grupos genéticos, os Ch apresentaram maior longissimus dorsi. Na primeira gera o de cruzamento (G1), animais 1/2 Ch apresentaram maior marmoreio e teor de extrato etéreo e menor quebra à coc o que os 1/2 Ne. Entre os animais G2, os animais 3/4 Ne mostraram maior quebra ao descongelamento e teor de extrato etéreo na carne. Na G1, o nível de heterose chegou a 18,54% para área de longissimus dorsi, 28,10% para teor de extrato etéreo e 64,01% para marmoreio da carne. Na G2, a heterose foi de -17,37% para a textura da carne e 10,40% para área de longissimus dorsi.
