Adaptative Network Topology for Data Centers
2016
Data centers have an important role in supporting cloud computing services (such as email, social networking, web search, etc.) enterprise computing needs, and infrastructure-based services. Data center networking is a research topic that aims at improving the overall performances of the data centers. It is a topic of high interest and importance for both academia and industry. Several architectures such as FatTree, FiConn, DCel, BCube, and SprintNet have been proposed. However, these topologies try to improve the scalability without any concerns about energy that data centers use and the network infrastructure cost, which are critical parameters that impact the performances of data centers…
Uncertainty in urban flood damage assessment due to urban drainage modelling and depth-damage curve estimation
2010
Due to the increased occurrence of flooding events in urban areas, many procedures for flood damage quantification have been defined in recent decades. The lack of large databases in most cases is overcome by combining the output of urban drainage models and damage curves linking flooding to expected damage. The application of advanced hydraulic models as diagnostic, design and decision-making support tools has become a standard practice in hydraulic research and application. Flooding damage functions are usually evaluated by a priori estimation of potential damage (based on the value of exposed goods) or by interpolating real damage data (recorded during historical flooding events). Hydrau…
Comparison of the whole slide imaging and conventional light microscopy in the grading of oral epithelial dysplasia: a multi-institutional study
2020
Made available in DSpace on 2021-06-25T11:48:03Z (GMT). No. of bitstreams: 0 Previous issue date: 2021-01-01 Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) Background: Whole Slide Imaging (WSI) is an alternative method to light microscopy (LM). However, few studies have compared the diagnostic agreement between WSI and LM, especially to grade oral epithelial dysplasia (OED). The purpose of this study was to evaluate the variability in grading OED by the World Health Organization grading system, using WSI and conventional LM, and to investigate whether the access to clinical information, and psychologic or phy…
Koinzidenz von Plattenepithelkarzinomen der Speiseröhre und Kopf-Hals-Karzinomen: Risiko und Früherkennung
2007
Patients suffering from head and neck cancer (HNC) have or will develop a second esophageal squamous cell cancer (ESCC) in 5 - 14 %. When a second esophageal neoplasm occurs in a HNC patient, the prognosis is generally determined by the ESCC, and unfortunately it is poor. Prospective clinical studies in Japan, Brazil, Taiwan, France and Germany have shown that screening or surveillance using Lugol chromoesophagoscopy enables early detection of second esophageal neoplasias. Such a surveillance results in a survival benefit for HNC patients. Vice versa, ESCC patients also have a risk of 9.3 - 11.4 % for a head and neck cancer. Periodic otolaryngeal examination and pharyngoscopy is recommended…
The Magical Treasure and Its Guardians
2012
On 17 June 1499, John and Agnes Clerk from Great Ashfield as well as their young daughter Marion had to answer charges before the consistory court of Norwich. The ecclesiastical court had learned that the girl worked as a healer and a soothsayer, and that she claimed she could locate buried treasures. Marion admitted everything immediately, even with an air of self-importance. She said that she got her abilities from God, the Virgin Mary and from the fairies. The ecclesiastical judge seems to have amused himself asking the girl about the details. The fairies, Marion explained, were little people who gave her information whenever she needed it. They did not believe in Jesus and the Holy Spir…
Why are viral genomes so fragile? The bottleneck hypothesis
2021
If they undergo new mutations at each replication cycle, why are RNA viral genomes so fragile, with most mutations being either strongly deleterious or lethal? Here we provide theoretical and numerical evidence for the hypothesis that genetic fragility is partly an evolutionary response to the multiple population bottlenecks experienced by viral populations at various stages of their life cycles. Modelling within-host viral populations as multi-type branching processes, we show that mutational fragility lowers the rate at which Muller’s ratchet clicks and increases the survival probability through multiple bottlenecks. In the context of a susceptible-exposed-infectious-recovered epidemiolog…
On prefix normal words and prefix normal forms
2016
A $1$-prefix normal word is a binary word with the property that no factor has more $1$s than the prefix of the same length; a $0$-prefix normal word is defined analogously. These words arise in the context of indexed binary jumbled pattern matching, where the aim is to decide whether a word has a factor with a given number of $1$s and $0$s (a given Parikh vector). Each binary word has an associated set of Parikh vectors of the factors of the word. Using prefix normal words, we provide a characterization of the equivalence class of binary words having the same set of Parikh vectors of their factors. We prove that the language of prefix normal words is not context-free and is strictly contai…
Fast Graph Filters for Decentralized Subspace Projection
2020
A number of inference problems with sensor networks involve projecting a measured signal onto a given subspace. In existing decentralized approaches, sensors communicate with their local neighbors to obtain a sequence of iterates that asymptotically converges to the desired projection. In contrast, the present paper develops methods that produce these projections in a finite and approximately minimal number of iterations. Building upon tools from graph signal processing, the problem is cast as the design of a graph filter which, in turn, is reduced to the design of a suitable graph shift operator. Exploiting the eigenstructure of the projection and shift matrices leads to an objective whose…
Neck Pain Rehabilitation
2016
Neck pain is par excellence one of the most common disorders of the musculoskeletal system, second only to low back pain. It constitutes 40 % of all backache. The International Association for the Study of Pain (IASP) defines pain of cervical origin coming from an area between the nuchal line and another imagi-nary line that passes through the lower end of the spinous process of the first thoracic vertebra and the sagittal plans tangent to the side edges of the neck. This definition considers therefore posterior pain which in turn can be divided into high pain, up to C3, and lower pain, down from C4. Also, as all diseases, it can be divided into acute and chronic neck pain, merely according…
