Maintaining SLOs of Cloud-Native Applications Via Self-Adaptive Resource Sharing (2019)

With changing workloads, cloud service providers can leverage vertical container scaling (adding/removing resources) so that Service Level Objective (SLO) violations are minimized and spare resources are maximized. In this paper, we investigate a solution to the self-adaptive problem of vertical elasticity for co-located containerized applications. First, the system learns performance models that relate SLOs to workload, resource limits and service level indicators. Second, it derives limits that meet SLOs and minimize resource consumption via a combination of optimization and restricted brute-force search. Third, it vertically scales containers based on the derived limits. We evaluated our technique on a Kubernetes private cloud of 8 nodes with three deployed applications. The results registered two SLO violations out of 16 validation tests; acceptably low derivation times facilitate realistic deployment. Violations are primarily attributed to application specifics, such as garbage collection, which require further research to be circumvented.

Operative Treatment of Acetabular Fractures Through the Ilioinguinal Approach A 10-Year Perspective (1994)

The ilioinguinal surgical approach was found to be effective for treatment of 119 (about 33%) of the 373 acetabular fractures treated operatively by the author over a 10-year period. It is indicated for anterior wall, anterior column, associated anterior and posterior hemitransverse fractures, as well as certain both column and transverse fractures. The approach offers the advantages of a cosmetic incision, rapid recovery of muscle function, and minimal ectopic bone formation. Complications included 3% surgical wound infection, 2% iatrogenic nerve palsy, 1% significant ectopic bone, and 1% death from pulmonary embolus. Clinical results at a minimum of 1-year, and an average of 3-years' followup, were, excellent in 37%, good in 47%, fair in 14%, and poor in 2%. Two patients later required total hip arthroplasty for posttraumatic arthritis.
CommOnCV (2002)

This paper presents the project CommOnCV, which aims at dealing with the problematics of e---recruitment by considering a new approach based on competency management. The idea consists of allowing a job seeker (respectively a recruiter to identify and formally represent the competencies underlying its Curriculum Vitae (respectively its job offer). These competencies, which allow to make explicit knowledge, skills, abilities, traits and motives acquired by a person (respectively required for a job), are then used to refine the matching process between "supply and demand". In other words, the objective of CommOnCV is to provide to the end-users of websites dedicated to e---recruitment new job-matching services based on competency management. From a technical viewpoint, these competencies are represented by a set of CV's annotations, which are formally represented by using semantic web languages such as RDF/RDFs or DAML+OIL. These annotations, which respect a particular model of competency, are defined according to domain ontologies. These ontologies can be related to a specific sector like Finance/Banking or Healthcare (in this context, the ontology includes the description of jobs and their associated tasks, the description of knowledge, skills and abilities related to these jobs, the organizations of the leader firms, etc.) and/or to a particular enterprise (in this case, the ontology includes the description of more specific tasks exclusively performed by the considered enterprise, organizational, technological and cultural aspects, etc.).

Polymerization of Ethylene by Silica‐Supported Dinuclear Cr<sup>III</sup> Sites through an Initiation Step Involving CH Bond Activation (2014)

Abstract The insertion of an olefin into a preformed metal–carbon bond is a common mechanism for transition‐metal‐catalyzed olefin polymerization. However, in one important industrial catalyst, the Phillips catalyst, a metal–carbon bond is not present in the precatalyst. The Phillips catalyst, CrO 3 dispersed on silica, polymerizes ethylene without an activator. Despite 60 years of intensive research, the active sites and the way the first CrC bond is formed remain unknown. We synthesized well‐defined dinuclear Cr II and Cr III sites on silica. Whereas the Cr II material was a poor polymerization catalyst, the Cr III material was active. Poisoning studies showed that about 65 % of the Cr III sites were active, a far higher proportion than typically observed for the Phillips catalyst. Examination of the spent catalyst and isotope labeling experiments showed the formation of a Si–(μ‐OH)–Cr III species, consistent with an initiation mechanism involving the heterolytic activation of ethylene at Cr III O bonds.
Application of color mixing for safety and quality inspection of agricultural products (2005)

In this paper, color-mixing applications for food safety and quality was studied, including two-color mixing and three-color mixing. It was shown that the chromaticness of the visual signal resulting from two- or three-color mixing is directly related to the band ratio of light intensity at the two or three selected wavebands. An optical visual device using color mixing to implement the band ratio criterion was presented. Inspection through human vision assisted by an optical device that implements the band ratio criterion would offer flexibility and significant cost savings as compared to inspection with a multispectral machine vision system that implements the same criterion. Example applications of this optical color mixing technique were given for the inspection of chicken carcasses with various diseases and for the detection of chilling injury in cucumbers. Simulation results showed that discrimination by chromaticness that has a direct relation with band ratio can work very well with proper selection of the two or three narrow wavebands. This novel color mixing technique for visual inspection can be implemented on visual devices for a variety of applications, ranging from target detection to food safety inspection.
GaN-based Vertical-Cavity Surface-Emitting Lasers Incorporating Dielectric Distributed Bragg Reflectors (2019)

This paper reviews past research and the current state-of-the-art concerning gallium nitride-based vertical-cavity surface-emitting lasers (GaN-VCSELs) incorporating distributed Bragg reflectors (DBRs). This paper reviews structures developed during the early stages of research into these devices, covering both major categories of GaN-based VCSELs: hybrid-DBR and all-dielectric-DBR. Although both types exhibited satisfactory performance during continuous-wave (CW) operation in conjunction with current injection as early as 2008, GaN-VCSELs have not yet been mass produced for several reasons. These include the difficulty in controlling the thicknesses of nitride semiconductor layers in hybrid-DBR type devices and issues related to the cavity dimensions in all-dielectric-DBR units. Two novel all-dielectric GaN-based VCSEL concepts based on different structures are examined herein. In one, the device incorporates dielectric DBRs at both ends of the cavity, with one DBR embedded in n-type GaN grown using the epitaxial lateral overgrowth technique. The other concept incorporates a curved mirror fabricated on (000-1) GaN. Both designs are intended to mitigate challenges regarding industrial-scale processing that are related to the difficulty in controlling the cavity length, which have thus far prevented practical applications of all-dielectric GaN-based VCSELs.
A Cross-Coupled Iterative Learning Control Design for Precision Motion Control (2008)

This paper presents an improved method for precision motion control by combining individual axis iterative learning control (ILC) and cross-coupled ILC (CCILC) into a single control input. CCILC is a new method in which a multi-axis cross-coupled controller (CCC) is reformatted into a single-input single-output (SISO) ILC format. Applying the techniques of ILC to CCC enables learning of the cross-coupled error which leads to a modified control signal and subsequent improvements in the contour trajectory tracking performance. In this paper, performance of the combined ILC and CCILC system is compared to standard feedback control through computer simulations and experimental testing on a Cartesian robotic system. Sufficient stability and convergence properties for the combined system are presented along with a modified approach for determining monotonic convergence of systems that are computationally challenging. The combined design is shown to enhance the precision motion control of the robotic system through performance improvements in individual axis tracking and contour tracking.
Conducting a field study of stress: general principles (2006)

In recent years, interest in the study of stress has expanded, particularly in the disciplines of anthropology and human biology where the focus of research has drifted toward evaluating the adaptive biological, cultural and psychological responses to stressors inherent in everyday living. Field studies of stress in these disciplines have been conducted across a wide continuum of contexts. These range from an assessment of the stress of "modernization" where biological and cultural responses of populations undergoing rapid industrialization/Westernization are examined, e.g. James et al. (1985), to the responses of people facing novel, new environments in modern, Western societies, such as occur in nursing homes (Ice et al., 2002).
Context Driven Scene Parsing with Attention to Rare Classes (2014)

This paper presents a scalable scene parsing algorithm based on image retrieval and superpixel matching. We focus on rare object classes, which play an important role in achieving richer semantic understanding of visual scenes, compared to common background classes. Towards this end, we make two novel contributions: rare class expansion and semantic context description. First, considering the long-tailed nature of the label distribution, we expand the retrieval set by rare class exemplars and thus achieve more balanced superpixel classification results. Second, we incorporate both global and local semantic context information through a feedback based mechanism to refine image retrieval and superpixel matching. Results on the SIFTflow and LMSun datasets show the superior performance of our algorithm, especially on the rare classes, without sacrificing overall labeling accuracy.
Cholesterol Phosphate Derivatives:  Synthesis and Incorporation into a Phosphatase and Calcium-Sensitive Triggered Release Liposome (1998)

A series of cholesterol derivatives that position a phosphate monoester at increasing distance from the sterol ring system was synthesized, and their utility as a triggered release liposome tested. Stable anionic liposomes consisting of the novel cholesterol phosphate derivatives and dioleoylphosphatidylethanolamine (DOPE) can be induced to collapse upon phosphatase-catalyzed removal of the phosphate group. Control liposomes containing DOPE and cholesterol phosphate or phosphatidic acid, which are not phosphatase substrates, do not undergo phosphatase-mediated collapse. The phosphatase-sensitive liposomes also collapse in the presence of calcium. The precise concentration of calcium that induces the collapse is controlled by the structure of the cholesterol phosphate derivative. Plasmid DNA encoding luciferase, encapsulated in the cholesterol derivative/DOPE liposomes, transfected cells in vitro. The level of transfection is dependent upon the cholesterol derivative and is mediated by both a calcium-independent and a calcium-dependent pathway; however, the involvement of phosphatase in the latter mechanism is not yet resolved. The transfection efficiency is between 10(6) and 10(7) of luciferase activity in relative light units per milligram of protein, which is similar to transfection values reported using other triggered release liposomes.
Behind the scenes of functional brain imaging: A historical and physiological perspective (1998)

At the forefront of cognitive neuroscience research in normal humans are the new techniques of functional brain imaging: positron emission tomography and magnetic resonance imaging. The signal used by positron emission tomography is based on the fact that changes in the cellular activity of the brain of normal, awake humans and laboratory animals are accompanied almost invariably by changes in local blood flow. This robust, empirical relationship has fascinated scientists for well over a hundred years. Because the changes in blood flow are accompanied by lesser changes in oxygen consumption, local changes in brain oxygen content occur at the sites of activation and provide the basis for the signal used by magnetic resonance imaging. The biological basis for these signals is now an area of intense research stimulated by the interest in these tools for cognitive neuroscience research.

Nosology and classification of genetic skeletal disorders: 2010 revision (2011)

Genetic disorders involving the skeletal system arise through disturbances in the complex processes of skeletal development, growth and homeostasis and remain a diagnostic challenge because of their variety. The Nosology and Classification of Genetic Skeletal Disorders provides an overview of recognized diagnostic entities and groups them by clinical and radiographic features and molecular pathogenesis. The aim is to provide the Genetics, Pediatrics and Radiology community with a list of recognized genetic skeletal disorders that can be of help in the diagnosis of individual cases, in the delineation of novel disorders, and in building bridges between clinicians and scientists interested in skeletal biology. In the 2010 revision, 456 conditions were included and placed in 40 groups defined by molecular, biochemical, and/or radiographic criteria. Of these conditions, 316 were associated with mutations in one or more of 226 different genes, ranging from common, recurrent mutations to "private" found in single families or individuals. Thus, the Nosology is a hybrid between a list of clinically defined disorders, waiting for molecular clarification, and an annotated database documenting the phenotypic spectrum produced by mutations in a given gene. The Nosology should be useful for the diagnosis of patients with genetic skeletal diseases, particularly in view of the information flood expected with the novel sequencing technologies; in the delineation of clinical entities and novel disorders, by providing an overview of established nosologic entities; and for scientists looking for the clinical correlates of genes, proteins and pathways involved in skeletal biology.
Nonlinear economic Model Predictive Control for SI engines based on Sequential Quadratic Programming (2016)

This paper proposes a model predictive torque control strategy for Spark Ignition (SI) engines with external Exhaust Gas Recirculation (EGR). The proposed Nonlinear (economic) Model Predictive Controller (NMPC) tries to minimize fuel consumption with given Indicate Mean Effective Pressure (IMEP) tracking reference and abnormal combustion constraints like knock and combustion stability. A Nonlinear Programming (NLP) problem is formulated and solved using Sequential Quadratic Programming (SQP) to obtain the desired control actions. The SQP exploits the Gauss-Newton like structure of the real time NLP problem to simplify computation of Hessian matrix. Simulation results demonstrate that the proposed model predictive IMEP control can track the IMEP reference for engine cycles without active constraints (with a RMS tracking error of 1.1%). When the IMEP reference conflicts with constraints, the SQP MPC can efficiently find close to optimal control actions that are similar to those from off-line feed forward calibration.
Transcutaneous supraorbital neurostimulation in “de novo” patients with migraine without aura: the first Italian experience (2015)

In patients experiencing a low frequency of attacks, significant improvements in multiple migraine severity parameters were observed following a brief period of high frequency tSNS. Therefore, tSNS may be considered a valid option for the preventive treatment of migraine attacks in patients who cannot or are not willing to take daily medications, or in whom low migraine frequency and/or intensity would not require pharmacological preventive therapies.
CONSEQUENCES OF INDIVIDUALS' FIT AT WORK: A META‐ANALYSIS OF PERSON–JOB, PERSON–ORGANIZATION, PERSON–GROUP, AND PERSON–SUPERVISOR FIT (2005)

This meta‐analysis investigated the relationships between person–job (PJ), person–organization (PO), person–group, and person–supervisor fit with preentry (applicant attraction, job acceptance, intent to hire, job offer) and postentry individual‐level criteria (attitudes, performance, withdrawal behaviors, strain, tenure). A search of published articles, conference presentations, dissertations, and working papers yielded 172 usable studies with 836 effect sizes. Nearly all of the credibility intervals did not include 0, indicating the broad generalizability of the relationships across situations. Various ways in which fit was conceptualized and measured, as well as issues of study design, were examined as moderators to these relationships in studies of PJ and PO fit. Interrelationships between the various types of fit are also meta‐analyzed. 25 studies using polynomial regression as an analytic technique are reviewed separately, because of their unique approach to assessing fit. Broad themes emerging from the results are discussed to generate the implications for future research on fit.
Intelligent Information Processing Technology in Teaching Reform of Computer Specialty (2021)

With the development of information technology, computer education is paid more and more attention. However, in the face of the same new development of computer technology, there are still many problems in the teaching of computer major. Intelligent information processing technology is a kind of modern technology, which can realize the collection and arrangement of data information and make the data clear. This paper studies the application of intelligent information processing technology in the teaching reform of computer specialty. In the research, we use the principal component analysis method of intelligent information processing technology, through questionnaire survey and literature analysis, to study the teaching and reform of computer major, sort out the key problems, and put forward some reform suggestions. This study found that there are many problems in the teaching of computer science, among which the most prominent problems are backward teaching methods and low teaching efficiency, accounting for 31%. In addition, there are some other problems that need to be paid attention to. Thus, we can see that the application of intelligent information processing technology in the teaching reform of computer specialty can make the data become clear and clear, which is conducive to us to find the key of problems and provide solutions for better solving problems.
Validated Feasibility Study of Integrally Stiffened Metallic Fuselage Panels for Reducing Manufacturing Costs (2000)

The continual need to reduce airframe cost and the emergence of high speed machining and other manufacturing technologies has brought about a renewed interest in large-scale integral structures for aircraft applications. Applications have been inhibited, however, because of the need to demonstrate damage tolerance, and by cost and manufacturing risks associated with the size and complexity of the parts. The Integral Airframe Structures (IAS) Program identified a feasible integrally stiffened fuselage concept and evaluated performance and manufacturing cost compared to conventional designs. An integral skin/stiffener concept was produced both by plate hog-out and near-net extrusion. Alloys evaluated included 7050-T7451 plate, 7050-T74511 extrusion, 6013-T6511 extrusion, and 7475-T7351 plate. Mechanical properties, structural details, and joint performance were evaluated as well as repair, static compression, and two-bay crack residual strength panels. Crack turning behavior was characterized through panel tests and improved methods for predicting crack turning were developed. Manufacturing cost was evaluated using COSTRAN. A hybrid design, made from high-speed machined extruded frames that are mechanically fastened to high-speed machined plate skin/stringer panels, was identified as the most cost-effective manufacturing solution. Recurring labor and material costs of the hybrid design are up to 61 percent less than the current technology baseline.
