SOL: Safe On-Node Learning in Cloud Platforms [article]

Yawen Wang, Daniel Crankshaw, Neeraja J. Yadwadkar, Daniel Berger, Christos Kozyrakis, Ricardo Bianchini
2022 arXiv   pre-print
Cloud platforms run many software agents on each server node. These agents manage all aspects of node operation, and in some cases frequently collect data and make decisions. Unfortunately, their behavior is typically based on pre-defined static heuristics or offline analysis; they do not leverage on-node machine learning (ML). In this paper, we first characterize the spectrum of node agents in Azure, and identify the classes of agents that are most likely to benefit from on-node ML. We then

SOL provides a simple API to agent developers and manages the scheduling and running of the agent-specific functions they write. We illustrate the use of SOL by implementing three ML-based agents that manage CPU cores, node power, and memory placement. Our experiments show that (1) ML substantially improves our agents, and (2) SOL ensures that agents operate safely under a variety of failure conditions. We conclude that ML-based agents show significant potential and that SOL can help build them.

2019 Zenodo  
The potential of satellite-based interferometry for landslides activity definition is well known. Many applications have demonstrated that this technique represents a strong supporting tool for landslide risk assessment and monitoring, at both local and regional scale. The ESA' Sentinel-1 (S1) constellation acquires with high revisit-time in a conflict-free operational mode, timely distributing data without costs or restrictions. All these characteristics allow relying upon S1 service for a

For this reason, more and more research projects are based on the use of S1 in geohazards monitoring and early warning. The aim of this work is to present the results achieved in the framework of the European Project (ECHO) U-Geohaz regarding landslides monitoring and early warning supporting tools based on S1. The study area of the project is the Valle d'Aosta region (VDA) that is widely affected by landslide process of different size and typology. Specifically, the Deep-Seated Gravitational Slope Deformations (DSGSDs) are the most representative in terms of area coverage. The study of the state of activity and evolution of these phenomena is very important because DSGSDs affect entire valley flanks and several villages have been built on them or nearby. The use of S1-based interferometry can potentially give a near-real time information on their activity over the whole region supporting decision makers and early warning systems. At the same time, VDA presents challenging characteristics for what concerns the radar response and thus the obtainable results. The main limiting factor is the snow coverage, which is also strongly related to the topography. The topographic relief is highly variable, ranging from 300 m a.s.l. to peaks higher than 4000 m a.s.l. with steep slopes. The regional climate is characterized by wide range of temperatures varying a lot from the mountainous zone to the bottom of the valleys, implying also a st [...]

Cluster Innovation Capability: a systematic review

Bruno Anicet Bittencourt, Mariana Bianchini Galuk, Vanessa Marques Daniel, Aurora Carneiro Zen
2018 International Journal of Innovation  
Most studies on innovation capability analyze the firm level. Little efforts have been made to understand the interactions that take place in inter-organizational agglomerations and the capabilities that such arrangements retain. This study aims to develop a theoretical framework of cluster innovation capability. The academic production about innovation capability of clusters in the business field from 2005 to 2014 was analyzed and the databases consulted were: EBSCO, SCOPUS, and Web of

Analysis of Flat Plate Honeycomb Seals Aerodynamic Losses: Effects of Clearance

Daniele Massini, Bruno Facchini, Mirko Micio, Cosimo Bianchini, Alberto Ceccherini, Luca Innocenti
2014 Energy Procedia  
Among the various type of seals used in gas turbine secondary air system to guarantee sufficient confinement of the main gas path, honeycomb seals well perform in terms of enhanced stability and reduced leakage flow. Reliable estimates of the sealing performance of honeycomb packs employed in industrial gas and steam turbines, are however missing in literature, thus, in order to evaluate the complete characteristic curve of the seals in the wide range of working conditions, an experimental

Due to the generally large amount of honeycomb cells typically present in real seals, it would be convenient to treat the sealing effect of the honeycomb pack as an increased distributed friction factor on the plain top surface that is why the simplest configuration, the honeycomb facing a flat plate, is employed in this paper. The geometry of the hexagonal cell and the investigated clearances were chosen to well represent actual honeycomb packs employed in industrial compressors. First the pressure distribution within the seal was analysed verifying that downstream the first 5 rows of cells, where entrance effects are predominant, the relative pressure drop is almost constant thus the use of an equivalent friction factor is appropriate to characterize the seal. Subsequent analysis focused on the characterization of the friction factor as function of the Reynolds number with the aim of establishing the proper geometrical scaling to achieve flow conditions similar to real turbine most critical ones. The different behaviour of the honeycomb sealing depending on the hexagonal cell arrangement and dimensions was evaluated in terms of friction factor. Comparison with results coming from a previous CFD investigation is also presented and discussed in this paper.

The search strategy adopted was based on (P.I.C.O.) structured questions (from the initials "Patient"; "Intervention"; "Control" and "Outcome". The resulting search syntax for non-specific neck pain was: Question 1: neck pain AND (analgesics OR paracetamol OR acetaminophen OR dipyrone OR non narcotics OR analgesics OR opioid); Question 2: neck pain AND (muscle relaxants OR ciclobenzaprine OR carisoprodol); Question 3: neck pain AND (non-steroidal anti-inflammatory agents); Question 4: neck pain AND (physical modalities OR hyperthermia induced OR diathermy OR ultrasonic therapy OR electric stimulation OR ultrasound OR transcutaneous electric nerve stimulation OR TENS); Question 5: neck pain AND (exercise therapy OR physical activity); Question 6: (neck pain OR myofascial pain syndromes) AND (massage OR manual therapy); Question 7: (neck pain OR myofascial pain syndromes) AND (posture OR ergonomic OR ergometry); Question 8: neck pain AND (sleep OR posture); Question 9: (neck pain OR myofascial neck pain) AND (acupuncture therapy OR trigger points; Question 10: neck pain AND education; Question 11: neck pain AND (psychology OR interdisciplinary communication OR interprofessional relations OR cognitive behaviour therapy OR work style intervention); Question 12: neck pain AND (mechanical OR manipulation); Question 13: neck pain AND (nerve blocks OR local anesthetics); Question 14: (neck pain OR myofascial pain syndrome) AND botulinum Toxin; On all searches, we used Field: All Fields, Limits: no age limits, with metodological filter for study types: narrow. In this manner, we found 1495 articles. Next, based on the abstracts, we selected the ninety-one papers related to neck pain and its treatment. We classified the scientific evidence strength of these studies according to the Oxford Centre for Evidence Based Medicine guidelines. The randomized and controlled clinical essays were submitted to critical evaluation according to the Jadad scale, 1996. Finally, we selected the forty-seven references which, due to greater scientific evidence strength, consistence, and clinical relevance, gave support to the recommendations of this directive. LEVEL OF RECOMMENDATION AND EVIDENCE: A: Strong consistency experimental or observational studies. B: Fair consistency experimental or observational studies. C: Case reports (uncontrolled studies). D: Opinion lacking critical evaluation, based on consensus, physiological studies or animal models. OBJECTIVES: Offering information about the rehabilitation of chronic non-specific neck pain.

RESUMO O cambucizeiro (Campomanesia phaea), pertencente à família Myrtaceae, é uma planta nativa da Mata Atlântica brasileira. A descrição das características dos frutos de cambucizeiro é importante para subsidiar novos trabalhos de melhoramento genético e sua exploração comercial, principalmente no que tange ao processamento dos frutos.

Quarenta frutos de cada acesso foram coletados no mês de maio e submetidos às seguintes análises: diâmetro longitudinal e transversal, massa fresca total dos frutos, número e massa das sementes, sólidos solúveis totais, % ácido cítrico, ratio, firmeza, vitamina C e coloração. A conformidade dos frutos varia intensamente entre os acessos. O número de sementes não é um bom indicativo para a relação com a massa do fruto, mas sim a massa de mil sementes. Alguns acessos possuem elevado teor de sólidos solúveis, mas, por outro lado, a grande maioria possui frutos com elevada acidez. Cambuci é uma excelente fonte de vitamina C. Os frutos dos acessos são de coloração verde, persistindo uma tonalidade opaca quando maduros.

Origin of Co-Expression Patterns in E.coli and S.cerevisiae Emerging from Reverse Engineering Algorithms

Mattia Zampieri, Nicola Soranzo, Daniele Bianchini, Claudio Altafini, Mark Isalan
2008 PLoS ONE  
The concept of reverse engineering a gene network, i.e., of inferring a genome-wide graph of putative genegene interactions from compendia of high throughput microarray data has been extensively used in the last few years to deduce/integrate/validate various types of "physical" networks of interactions among genes or gene products. Results: This paper gives a comprehensive overview of which of these networks emerge significantly when reverse engineering large collections of gene expression data
more » ... for two model organisms, E.coli and S.cerevisiae, without any prior information. For the first organism the pattern of co-expression is shown to reflect in fine detail both the operonal structure of the DNA and the regulatory effects exerted by the gene products when co-participating in a protein complex. For the second organism we find that direct transcriptional control (e.g., transcription factor-binding site interactions) has little statistical significance in comparison to the other regulatory mechanisms (such as co-sharing a protein complex, colocalization on a metabolic pathway or compartment), which are however resolved at a lower level of detail than in E.coli. Conclusion: The gene co-expression patterns deduced from compendia of profiling experiments tend to unveil functional categories that are mainly associated to stable bindings rather than transient interactions. The inference power of this systematic analysis is substantially reduced when passing from E.coli to S.cerevisiae. This extensive analysis provides a way to describe the different complexity between the two organisms and discusses the critical limitations affecting this type of methodologies.

Benefits of extracorporeal shockwave in the treatment of skin ulcers: a literature review

Marcus Yu Bin Pai, Juliana Takiguti Toma, Danielle Bianchini Rampim, Marta Imamura, Linamara Rizzo Battistella
2016 Acta Fisiátrica  
Extracorporeal shockwave therapy (ESWT) has analgesic and anti-inflammatory effects. With the evolution and comprehension of its biological and physical mechanisms, the application of ESWT on other pathologies has also been studied, especially in musculoskeletal diseases. Recently, studies on animal models have shown its angiogenic capacity and a higher rate of local re-epithelization. These small studies led to few trials using low-energy, radial ESWT to treat problematic chronic skin ulcers.
more » ... kin ulcers have diverse etiologies, ranging from pressure ulcers, burns, venous or arterial ulcers, and even diabetic ulcers. Their treatment is usually a challenge, due to the long-term treatment and high costs. Objective: To review the literature and evaluate the efficacy of ESWT in caring for skin ulcers of various etiologies: diabetic ulcers, pressure ulcers, burns, post-traumatic ulcers, venous and arterial ulcers. Method: A literature review was made, with only human trials included. Results: 9 articles were selected that fulfilled the eligibility criteria. The studies included evaluations of 788 patients. The manuscripts demonstrated a large variability regarding the interventions made. There was heterogeneity regarding intervention time, number of pulses, frequency of sessions, and also the number of sessions, energy density used, and the type of shock wave used in therapies. Some of the included trials found a higher rate of complete wound healing and faster epithelization in patients with chronic lesions, unresponsive to the traditional measures. However, there were few studies in the literature with proper methodological quality. Conclusion: ESWT is a promising alternative for the treatment of patients unresponsive to conventional measures. The results are promising, although the evidence regarding wound healing and acceleration of wound healing is still limited. The studies selected did not report any significant side effects.
