Malliavin Differentiability of the Generalized Heston Model

It is well known that Malliavin calculus can be applied to a stochastic differential equation with Lipschitz continuous coefficients in order to clarify the existence and the smoothness of the solution. In this paper, we apply Malliavin calculus to the CEV-type Heston model whose diffusion coefficient is non-Lipschitz continuous and prove the Malliavin differentiability of the model.
Hybrid electronic ballast operating the HPS lamp at constant power

A hybrid solid-state ballast is described that operates the HPS (high pressure sodium) lamp at mains frequency with constant power through rated life. The system utilizes two series-connected inductors and a bidirectional semiconductor switch connected in parallel to one of them. A lamp starting circuit has also been included in the ballast. The static switch, with phase angle control provided by power feedback, actuates on lamp current compensating variations of the mains voltage and/or the increase of lamp voltage. The system offers: a) an increase of lamp life and system lumen maintenance; b) power factor and total harmonic distortion of line current comparable to conventional lag ballasts; and c) operating cost savings, both in terms of energy cost and lamp replacement cost.
Fault detection and isolation on a PWM inverter by knowledge-based model

This paper presents an approach based on knowledge models to detect and localize faults in a PWM inverter supplying a synchronous machine. These faults don't affect the system protection. A diagnostic system which uses only the input variables of the drive is presented. It is based on the analysis of the current vector trajectory and of the instantaneous frequency in faulty mode. These two methods have been successfully applied to an experimental system.
Mechanisms and consequences of lung epithelial injury in severe RSV disease

The studies in this thesis have examined mechanisms and consequences of lung epithelial injury in severe RSV disease. In this context, they specifically contribute to the knowledge of apoptosis and the formation of pulmonary edema. The results of our studies underscore the complexity of the mechanisms underlying epithelial dysfunction and injury during severe RSV disease. The following conclusions can be drawn from this thesis: - Activation of the inflammatory response of the lungs to pneumonia virus of mice and mechanical ventilation is mediated by the Fas/FasL system (chapter 3) - PVM-induced epithelial injury is partly mediated by the Fas/FasL system (chapter 3) - The effect of the Fas/FasL system on inflammation in response to PVM and MV is not associated with a better outcome in fas-deficient mice with more advanced PVM disease (chapter 3) - The caspase inhibitor zVAD increases lung inflammation in pneumovirus infection in mice without affecting total lung caspase activity (chapter 4) - The majority of children with severe RSV disease that are admitted to the PICU for mechanical ventilation fulfill the criteria for ARDS (chapter 5) - FiO2 is an independent predictor for outcome (duration of mechanical ventilation (MV) and the length of stay (LOS)) in children with RSV-induced ARDS, whereas the PaO2/FiO2-ratio is not (chapter 5) - Intratracheal instillation of TIP does not affect pulmonary edema formation or clinical outcome in PVM-infected mice (chapter 6)
Effect of Laser Acupuncture on Hemodialysis Male Patient

Background: Kidney disease is a heterogeneous group of disorders affecting kidney structure and function . Pain and increases serum urea are usually associated with sever renal damage or failure. Dialysis may be used for those with an acute disturbance in kidney function or for those with progressive but chemically worsening kidney function a state know as chronic renal failure . The purpose was to investigate the impact of laser puncture on management of pain symptoms and urea reduction ratio (URR) in patients with chronic kidney disease (CKD). Material and methods: thirty male patients ranged age 35- 45 years who had chronic kidney diseases (CKD), were divided into two equal groups in number. Group (A) received laser puncture sessions plus their traditional medical treatment (medications and dialysis). Group (B) received their traditional medical treatment only (medications and dialysis). Results: there was a significant decrease in group (A) in pain intensity, but there was a non-significant difference in the urea reduction ratio (URR) in response to the designed laser puncture program. Conclusion: laser puncture had a significant effect to alleviate pain in patient with CKD.
Functional ability indices: measurement problems in assessing their validity.

: This study examines measurement problems which must be considered in assessing the validity of alternative measures of functional ability. Threats to meaningful evaluation of validity include problems of: (1) assessing the impact of aids, adaptations and helpers; (2) controlling for situational variation and motivational factors; (3) controlling for the professional perspective of the rater; and (4) controlling for the role expectations of the patient in the performance of certain functions. These problems were investigated using validity comparisons from the St. Thomas' Hospital elderly study in which questionnaire-based assessments of functional status were compared with assessments of physicians and visiting geriatric nurses. Clinician and questionnaire-based measurements were compared for 92 elderly (age 75 years and older) primary-care patients in terms of performance of 13 mobility and self-help functions. Trichotomous measures of performance controlled more adequately for the compensating effect of aids, adaptations, and helpers, and rater/questionnaire agreement was highest for more basic mobility and self-help functions. Test-retest reliability comparisons indicated that motivational factors and situational variation were minimized by reassessing the subjects in their own homes using members of their primary-care team. Levels of concordance between questionnaire ratings and clinical ratings show systematic variation indicating differences in the clinical perspectives of physicians and visiting nurses. Finally, variations in the reported and clinically-evaluated performance of male and female subjects appear to reflect the culturally determined role expectations of men and women as they relate to self-care.
Psychosocial burden differences between women of reproductive age and menopausal age due to abnormal Pap smear: A pilot study of the East Coast of Malaysia

Introduction: Women with abnormal Pap smear results are facing psychosocial problems such as fear, anxiety, mental stress, and defaulted follow-ups. This study aims to identify psychosocial burden differences in mean score between reproductive age group and menopausal age group women with abnormal Pap smear results. Materials and Methods: A total of seventy women with abnormal Pap smear results were recruited from three Ministry of Health, Tertiary Hospital on the East Coast of Malaysia (Kuala Terengganu, Kota Bharu, and Kuantan). The self-administered PEAPS-Q-14 questionnaire was answered by the participants and data were analyzed using descriptive and independent t-test. Results: Mean age of respondents was 44.79; the majority were Malays (84.3%) and Muslims (88.6%). Only two domains are significant differences between the age groups of <45 years and more than 45 years. These two significant domains are beliefs, feelings, and changes in perception of self (P > 0.003), and worry about human papillomavirus (HPV) infectivity (P < 0.005). Conclusion: Psychosocial burden due to abnormal Pap smear results in terms of mental stress, overwhelming beliefs, and feelings of guilt and worry of HPV infection and possibility of cervical cancer were noted more in reproductive age groups as compared to the menopausal age group. Health-care providers should be aware of these psychosocial effects whereby they can refer such patients to a gynecologic oncologist for proper counseling at the proper time so that the negative impact due to this psychosocial burden can be prevented.
Treatment of Submental Fat Deposit with Cholanic Acid Intra-Adipocyte Lipolysis Compared with Liposuction Prospective Study

Introduction: Over the years, liposuction has been the standard treatment for localized fatty deposit. Lipolysis is a controversial procedure based generally on phosphatidylcholine and deoxycholate injection. The purpose of this study was to compare the efficacy of cholanic acid Aqualyx with the efficacy of liposuction in women with moderate submental fatty collection. Materials and Methods: A prospective randomized study of 30 women with moderate submental fatty collection. Half of the subjects were treated with cholanic acid Aqualyx and the other half with liposuction. Responses were assessed clinically and statistically. Results: Although the lipolysis group showed a better response, it is difficult to conclude that adipocytolisis leads to greater fat reduction compared with liposuction.

LA ESPIRITUALIDAD EN EL PACIENTE ONCOLÓGICO: UNA FORMA DE NUTRIR LA ESPERANZA Y FOMENTAR UN AFRONTAMIENTO POSITIVO A LA ENFERMEDAD.

Se ha empezado a tomar en cuenta aspectos de espiritualidad y/o religiosidad (R/E) en el cuidado de los pacientes en estos ultimos anos. Numerosos trabajos de investigacion se estan abocando a este tema. El cancer es una enfermedad en aumento en Chile y el mundo. Representa una situacion de importante estres desde la etapa de diagnostico, durante el transcurso de la enfermedad y en etapas avanzadas de la enfermedad. La esperanza es una herramienta importante y beneficiosa en el afrontamiento y ajuste a la enfermedad oncologica. Actualmente, en Chile y en casi todo el mundo, se reconoce el derecho a recibir cuidados espirituales o religiosos, lo cual es aun mas relevante frente a la enfermedad oncologica. La espiritualidad y/o la religion afectan la toma de decisiones en etapas avanzadas de la enfermedad, e influyen en aspectos generales de la salud como en la calidad de vida de los pacientes. Pero las creencias espirituales y religiosas pueden tambien generar malestar y aumentar el peso del cancer. Esta dimension debe ser tomada en cuenta en la atencion en salud. Los principios del cuidado de la espiritualidad deben poder aplicarse en todas las fases de los enfermos sin independiente de las diversas culturas, tradiciones religiosas, y tipos de espiritualidad. Es importante seguir las guias sobre como lograr la atencion espiritual de calidad en los centros oncologicos y especialmente en los cuidados paliativos.
La distinction entre noms massifs et noms comptables Aspects linguistiques et conceptuels

En francais, certains noms communs, comme "lait", peuvent etre utilises avec l'article "du", mais moins facilement avec "un", tandis que d'autres, comme "chat", peuvent etre precedes par "un", mais rarement par "du". Ces noms ont ete respectivement appeles noms massifs et noms comptables. Ma these est consacree a l'etude de cette distinction linguistique. Le premier chapitre etablit qu'il s'agit d'une distinction syntaxique entre deux sous-classes des noms communs. Dans certains contextes, les noms massifs peuvent neanmoins etre convertis et employes comme des noms comptables, et vice versa. L'objectif principal devient alors de caracteriser la distinction entre noms massifs et noms comptables en termes semantiques. Les generalisations linguistiques proposees par la plupart des auteurs netiennent compte que des noms s'appliquant a des individus materiels. Elles sont critiquees dans les chapitres deux, trois et quatre. Les proprietes de reference distributive, cumulative et atomique souvent attribuees a ces noms y sont reconceptualisees. Il est montre qu'a un nom comptable est associe un principe d'unite qui specifie comment sont reliees les parties relatives d'un individu auquel s'applique le nom. Le chapitre cinq examine dans quelle mesure la distinction massif / comptable peut etre dite fondee sur une distinction ontologique. Les deux chapitres suivants etablissent que les proprietes semantiques isolees pour les noms du domaine materiel sont egalement satisfaites par les noms "abstraits" -tout au moins les noms d'evenement ("ascension") et d'activite ("marche"), etudiesau chapitre six, et les noms d'etat ("desordre"), de sentiment ("desir") et de qualite ("courage"), auxquels est consacre le chapitre sept. A l'aide des descriptions semantiques obtenues, les conversions entre noms massifs et noms comptables sont alors recensees et classees, leur fonctionnement semantique est caracterise et le role des facteurs pragmatiques dans leur interpretation est identifie.
Development of a multi-media book for clinical super- vision training in an undergraduate nursing programme

There is an increased interest in higher education in the use of e-learning resources for students. This can be attributed to many factors including, the availability of advanced technology systems, a growing student population that is technology focused, financial implications and the recruitment of international students. However, the introduction of technology and e-learning into teaching has given rise to issues regarding quality and quantity of educational practice. The challenge now is for educationalists is to deliver an optimal learning experience that is effective and appropriate for students’ learning
Fronto-Temporal Dementia: A Case Report

Fronto-temporal dementia (FTD) is the most common form of primary degenerative dementia after Alzheimer’s disease that affects middle age with an estimated prevalence at 15 per 100,000 in the population aged between 45 – 65 years. FTD is often misdiagnosed due to its early onset, clinical and pathological heterogeneity. Neuroimaging is known to assist in early diagnosis of these disorders. We present a case of a 59 year old woman with FTD.
Optimising dynamic binary modification across 64-bit Arm microarchitectures

A common optimisation used in most Dynamic Binary Modification (DBM) systems is trace generation as these traces improve locality and code layout. We describe an optimised code layout for traces as well as present how to adapt the runtime algorithm to generate it. In this way, we manage to reduce the overhead on all the Arm systems evaluated; 5 different microarchitectures. A major source of overhead for DBMs comes from handling indirect branches. Indirect Branch Inlining (IBI) is a mechanism that attempts to avoid this overhead by using predictions about the target of the indirect branch. We analyse the behaviour of the indirect branch inlining and propose a new predictor, Trace Restricted IBI (TRIBI), and how to optimise IBI given the new trace generation algorithm. Our evaluation shows a geometric mean overhead for SPEC CPU2006 of 9% for a Cortex-A53 (in-order core), and for out-of-order cores 11% on an X-Gene-2, 10% on a Cortex-A57, 7% on a Cortex-A72 and 8% on a Cortex-A73, when compared to native execution. This is a reduction of the overhead between 30% to 50% compared to the publicly available DBM systems MAMBO, and, even higher, against DynamoRIO. Using PARSEC 3.0, we evaluate the scalability across threads on the X-Gene-2 system (server machine with the highest number of cores) and show a geomean overhead between 6--8%.
Analytic resolution of time-domain half-space Green's functions for internal loads by a displacement potential-Laplace-Hankel-Cagniard transform method

A refined yet compact analytical formulation is presented for the time-domain elastodynamic response of a three-dimensional half-space subject to an arbitrary internal or surface force distribution. By integrating Laplace and Hankel transforms into a method of displacement potentials and Cagniard's inversion concept, it is shown that the solution can be derived in a straightforward manner for the generalized classical wave propagation problem. For the canonical case of a buried point load with a step time function, the response is proved to be naturally reducible with the aid of a parametrized Bessel function integral representation to six wave-group integrals on finite contours in the complex plane that stay away from all branch points and the Rayleigh pole except possibly at the starting point of the contours. On the latter occasions, the possible singularities of the integrals can be rigorously extracted by an extended method of asymptotic decomposition, rendering the residual numerical computation a simple exercise. With the new solution format, the arrival time of each wave group is derivable by simple criteria on the contour. Typical results for the time-domain response for an internal point force as well as the degenerate case of a surface point source are included for comparison and illustrations.
A Bike-sharing Optimization Framework Combining Dynamic Rebalancing and User Incentives

Bike-sharing systems have become an established reality in cities all across the world and are a key component of the Smart City paradigm. However, the unbalanced traffic patterns during rush hours can completely empty some stations, while filling others, and the service becomes unavailable for further users. The traditional approach to solve this problem is to use rebalancing trucks, which take bikes from full stations and deposit them at empty ones, reducing the likelihood of system outages. Another paradigm that is gaining steam is gamification, i.e., incentivizing users to fix the system by influencing their behavior with rewards and prizes. In this work, we combine the two efforts and show that a joint optimization considering both rebalancing and incentives results in a higher service quality for a lower cost than using simple rebalancing. We use simulations based on the New York CitiBike usage data to validate our model and analyze several schemes to optimize the bike-sharing system.
Integrated maintenance/spare parts management for manufacturing system according to variable production rate impacting the system degradation

This study develops an analytical model in order to determine an optimal integrated maintenance plan and spare parts management. We consider a manufacturing system, producing only one type of product, over a finite planning horizon H equal to the sum of all production periods and the production quantity of each period is known. This system is subject to a continuously increasing degradation rate. That is why a preventive maintenance strategy is adopted in order to face the increasing failure rate. We noted that contrarily to the majority of studies in literature, we take into account the impact of the production rate variation on the manufacturing system degradation and consequently on the adopted optimal maintenance strategy. In addition, the real need of spare parts relative to the scheduled maintenance actions is taken into account. In fact, the purpose of our study consists at determining the optimal preventive maintenance frequency and the optimal quantity of spare parts to order by minimizing a total cost, including maintenance and spare parts management. Numerical examples are presented along with a sensitivity study in order to prove the use of the developed model for deriving the optimal integrated strategy for any instance of the problem.
Macronutriments, masse grasse, flux d'acides gras et insulinosensibilité

L'obesite abdominale ou viscerale est une des composantes essentielles du syndrome metabolique (ou syndrome X). Les acides gras (AG) liberes par le tissu adipeux jouent un grand role dans la physiopathologie de l'insulino-resistance Le flux d'AG vers le foie est un des determinants majeurs de la production hepatique de triglycerides. La competition glucose-acides gras explique en partie l'insulino-resistance musculaire, mais les AG pourraient avoir un effet inhibiteur direct sur le transport du glucose. L'insulino-resistance est bien correlee avec la taille du pool intra-musculaire de triglycerides. Le phenomene de lipotoxicite a d'abord ete decrit au niveau de la cellule β. mais il concerne aussi de nombreux tissus utilisateurs de glucose. Ainsi la regulation de la distribution des acides gras entre les tissus et la partition de ceux-ci entre stockage et oxydation jouent un role central dans le developpement de l'insulino-resistance. Nous defendons l'idee que les macronutriments affectent la sensibilite a l'insuline par leurs interactions avec la regulation des flux d'AG. Les etudes des effets de l'alimentation sur la sensibilite a l'insuline sont convaincantes chez l'animal, mais il existe une discordance entre les etudes epidemiologiques et les etudes d'intervention chez l'homme. Les acides gras satures auraient des effets defavorables sur l'action de l'insuline alors que les acides gras polyinsatures auraient des effets favorables. Le role des glucides est moindre mais a fortes doses, le saccharose et le fructose peuvent diminuer la sensibilite a l'insuline. Les aliments a index glycemique bas et les fibres ont au contraire des effets protecteurs. La mesure therapeutique la plus efficace chez le sujet obese est d'obtenir une perte de poids par un regime hypocalorique, puis de maintenir la stabilite ponderale a long terme.
