A comparison among different Finite Control Set approaches and Convex Control Set Model-based Predictive Control applied in a Three-Phase Inverter with RL load (2019)

This paper presents a comparative study between two model-based predictive control (MPC) methods applied in a three-phase power inverter in terms of design and performance: finite control set (FCS-MPC) and convex control set (CCS-MPC). Moreover, different FCS-MPC strategies are tested. In order to analyze their advantages and disadvantages, it is shown a brief explanation about the inverter modeling and the control algorithms implementation. Note that the same parameters are used in the controllers numerical analyses, including unitary prediction horizon and an analytical solution for FCS-MPC. Furthermore, a different cost function for FCS-MPC is proposed in order to remove steady state error.
Calcium Sulfate and Platelet-Rich Plasma make a novel osteoinductive biomaterial for bone regeneration (2007)

This study showed that CS-Platelet is a novel biomaterial able to induce formation of bone in heterotopic and orthotopic sites, in orthotopic critical size bone defects, and in various clinical situations. The discovery of CS-Platelet may represent a cost-effective breakthrough in bone regenerative therapy and an alternative or an adjuvant to the current treatments.
Scalable SPARQL querying of large RDF graphs (2011)

The generation of RDF data has accelerated to the point where many data sets need to be partitioned across multiple machines in order to achieve reasonable performance when querying the data. Although tremendous progress has been made in the Semantic Web community for achieving high performance data management on a single node, current solutions that allow the data to be partitioned across multiple machines are highly inefficient. In this paper, we introduce a scalable RDF data management system that is up to three orders of magnitude more efficient than popular multi-node RDF data management systems. In so doing, we introduce techniques for (1) leveraging state-of-the-art single node RDF-store technology (2) partitioning the data across nodes in a manner that helps accelerate query processing through locality optimizations and (3) decomposing SPARQL queries into high performance fragments that take advantage of how data is partitioned in a cluster.
Two Bayesian treatments of the n-tuple recognition method (1995)

Two probabilistic interpretations of the n-tuple recognition method are put forward in order to allow this technique to be analysed with the same Bayesian methods used in connection with other neural network models. Elementary demonstrations are then given of the use of maximum likelihood and maximum entropy methods for tuning the model parameters and assisting their interpretation. One of the models can be used to illustrate the significance of overlapping n-tuple samples with respect to correlations in the patterns.
Twisted Graph States for Ancilla-driven Universal Quantum Computation (2009)

We introduce a new paradigm for quantum computing called Ancilla-Driven Quantum Computation (ADQC) which combines aspects both of the quantum circuit [D. Deutsch. Quantum computational networks. Proc. Roy. Soc. Lond A, 425, 1989] and the one-way model [R. Raussendorf and H. J. Briegel. A one-way quantum computer. Physical Review Letters, 86, 2001] to overcome challenging issues in building large-scale quantum computers. Instead of directly manipulating each qubit to perform universal quantum logic gates or measurements, ADQC uses a fixed two-qubit interaction to couple the memory register of a quantum computer to an ancilla qubit. By measuring the ancilla, the measurement-induced back-action on the system performs the desired logical operations. The underlying mathematical model is based on a new entanglement resource called twisted graph states generated from non-commuting operators, leading to a surprisingly powerful structure for parallel computation compared to graph states obtained from commuting generators. [M. Hein, J. Eisert, and H.J. Briegel. Multi-party entanglement in graph states. Physical Review A, 69, 2004. quant-ph/0307130]. The ADQC model is formalised in an algebraic framework similar to the Measurement Calculus [V. Danos, E. Kashefi, and P. Panangaden. The measurement calculus. Journal of ACM, 2007]. Furthermore, we present the notion of causal flow for twisted graph states, based on the stabiliser formalism, to characterise the determinism. Finally we demonstrate compositional embedding between ADQC and both the one-way and circuit models which will allow us to transfer recently developed theory and toolkits of measurement-based quantum computing and quantum circuit models directly into ADQC.
Microvesicles: ROS scavengers and ROS producers (2019)

This review analyzes the relationship between microvesicles and reactive oxygen species (ROS). This relationship is bidirectional; on the one hand, the number and content of microvesicles produced by the cells are affected by oxidative stress conditions; on the other hand, microvesicles can directly and/or indirectly modify the ROS content in the extra- as well as the intracellular compartments. In this regard, microvesicles contain a pro-oxidant or antioxidant machinery that may produce or scavenge ROS: direct effect. This mechanism is especially suitable for eliminating ROS in the extracellular compartment. Endothelial microvesicles, in particular, contain a specific and well-developed antioxidant machinery. On the other hand, the molecules included in microvesicles can modify (activate or inhibit) ROS metabolism in their target cells: indirect effect. This can be achieved by the incorporation into the cells of ROS metabolic enzymes included in the microvesicles, or by the regulation of signaling pathways involved in ROS metabolism. Proteins, as well as miRNAs, are involved in this last effect.
Systems integration and architecting: An overview of principles, practices, and perspectives (1998)

Systems Integration is an activity omnipresent in almost all of systems engineering and management. Often the term lacks precise definition and is used in different ways and for different purposes in the engineering of systems. This paper presents an overview of systems integration at all levels of system engineering and management. The goal of the paper is to present the various views of systems integration including lifecycle, architecture, process, interface, and enterprise, as well as product integration involving software and hardware. We examine systems engineering process, including several process models in an attempt to reveal the activities associated with integration during the engineering of systems. We review the characteristics of interfaces between systems of systems and users that generally give rise to many systems integration concerns. Without very careful effort at developing an appropriate architecture for a system, there will be little hope of integration. We discuss the role of systems management and knowledge integration in architecting for systems integration. Also presented are several contemporary perspectives on system architectures and their role in the engineering and integration of systems. © 1998 John Wiley & Sons, Inc. Syst Eng 1: 176–227, 1998
Towards next generation 3D teleconferencing systems (2012)

Teleconferencing is becoming more and more important and popular in today's society and is mostly accomplished using 2D video conferencing systems. However, we believe there is a lot of room for improving the communication experience: one crucial aspect is to add 3D information, but also freeing the user from sitting in front of a computer. With these improvements, we aim at eventually creating a fully immersive 3D telepresence system that might improve the way we communicate over long distances. In this paper we review and analyze existing technology to achieve this goal and present a proof-of-concept, but fully functional prototype.

 | Abstract: Traumatic asphyxia is a rare condition that occurs after compressive
 thoracoabdominal trauma, which is characterized by subconjunctival hemorrhage,
 cervicofacial cyanosis, edema and petechiae. Serious life-threatening thoracic
 and abdominal injuries may coexist. After conservatory treatment in most cases
 complete recovery is achieved, but in isolated cases permanent neurological
 lesions may occur. We present the case of the 39-year-old male patient who
 suffered a compressive thoracoabdominal trauma. The physical examination showed
 the characteristic “ecchymotic mask”. After surgical treatment of the abdominal
 injuries and intensive therapy the patient was discharged with permanent vision
 loss. The high retrograde venous pressure in the head and neck may be associated
 with neuronal ischemia, which can lead to irreversible optic nerve atrophy. It
 is therefore important to carry out an early, routine and complete ophtalmologic
 examination, especially in the intubated and poorly cooperative patients. Orv

Cathodoluminescence of single quantum wires and vertical quantum wells grown on a submicron grating (1994)

We present cathodoluminescence (CL) investigations of a corrugated GaAs/AlGaAs single quantum well (QW) structure grown on a submicron grating. The CL spectra have four distinct emission peaks. Using plan-view and cross-sectional CL imaging together with cross-sectional transmission electron microscope imaging, we have assigned the four peaks: They originate in the nominal QW, a quantum wire (QWR), a vertical quantum well (VQW), and the barrier, respectively. We have CL-imaged and -characterized single QWRs and VQWs.

Synthesis of coherent optical pulses using a field-programmable gate array (FPGA)-based gradient descent phase-locking algorithm with three semiconductor lasers (2015)

We demonstrate optical pulse synthesis through coherent combination of AOM-separated light by phase-locking feedback from an FPGA. An order of magnitude improvement in phase stability is shown, limited by the noise of the AOM driver.
Corrosion of Galvanized Strips in Florida Reinforced Earth Walls (2000)

The corrosion condition of the galvanized reinforcement in Florida Department of Transportation (FDOT) Mechanically Stabilized Earth Walls (MSEW) was determined at selected sites. For this purpose, 10 MSEW structures were instrumented at 8 different Florida sites for measurements of soil resistivity, electrical potential, and corrosion rates of both galvanized steel and plain steel by polarization resistance tests. The FDOT design standards for soil chemistry and particle size distribution were met in virtually all the test locations and structures tested. The reinforcements in the structures investigated were typically in good condition and the apparent corrosion rate of galvanized elements was low (average about 1 μm/year). A deterioration model for service life forecasting was formulated using the field survey input.

Prediabetes and risk of mortality, diabetes-related complications and comorbidities: umbrella review of meta-analyses of prospective studies (2021)

Abstract Aims/hypothesis The term prediabetes is used for individuals who have impaired glucose metabolism whose glucose or HbA 1c levels are not yet high enough to be diagnosed as diabetes. Prediabetes may already be associated with an increased risk of chronic ‘diabetes-related’ complications. This umbrella review aimed to provide a systematic overview of the available evidence from meta-analyses of prospective observational studies on the associations between prediabetes and incident diabetes-related complications in adults and to evaluate their strength and certainty. Methods For this umbrella review, systematic reviews with meta-analyses reporting summary risk estimates for the associations between prediabetes (based on fasting or 2 h postload glucose or on HbA 1c ) and incidence of diabetes-related complications, comorbidities and mortality risk were included. PubMed, Web of Science, the Cochrane Library and Epistemonikos were searched up to 17 June 2021. Summary risk estimates were recalculated using a random effects model. The certainty of evidence was evaluated by applying the GRADE tool. This study is registered with PROSPERO, CRD42020153227. Results Ninety-five meta-analyses from 16 publications were identified. In the general population, prediabetes was associated with a 6–101% increased risk for all-cause mortality and the incidence of cardiovascular outcomes, CHD, stroke, heart failure, atrial fibrillation and chronic kidney disease, as well as total cancer, total liver cancer, hepatocellular carcinoma, breast cancer and all-cause dementia with moderate certainty of evidence. No associations between prediabetes and incident depressive symptoms and cognitive impairment were observed (with low or very low certainty of evidence). The association with all-cause mortality was stronger for prediabetes defined by impaired glucose tolerance than for prediabetes defined by HbA 1c . Conclusions/interpretation Prediabetes was positively associated with risk of all-cause mortality and the incidence of cardiovascular outcomes, CHD, stroke, chronic kidney disease, cancer and dementia. Further high-quality studies, particularly on HbA 1c -defined prediabetes and other relevant health outcomes (e. g. neuropathy) are required to support the evidence. Graphical abstract
Acoustic Camera-Based Pose Graph SLAM for Dense 3-D Mapping in Underwater Environments (2020)

In this article, a novel dense underwater 3-D mapping paradigm based on pose graph simultaneous localization and mapping (SLAM) using an acoustic camera mounted on a rotator is proposed. The demands of underwater tasks, such as unmanned construction using robots, are growing rapidly. In recent years, the acoustic camera, which is a state-of-the-art forward-looking imaging sonar, has been gradually applied in underwater exploration. However, distinctive imaging principles make it difficult to gain an intuitive perception of an underwater environment. In this study, an acoustic camera with a rotator was used for dense 3-D mapping of the underwater environment. The proposed method first applies a 3-D occupancy mapping framework based on the acoustic camera rotating around the acoustic axis using a rotator at a stationary position to generate 3-D local maps. Then, scan matching of adjacent local maps is implemented to calculate odometry without involving internal sensors, and an approximate dense global map is built in real time. Finally, based on a graph optimization scheme, offline refinement is performed to generate a final dense global map. Our experimental results demonstrate that our 3-D mapping framework for an acoustic camera can achieve dense 3-D mapping of underwater environments robustly and accurately.
Skin flap complications after decompressive craniectomy and cranioplasty: Proposal of classification and treatment options (2016)

In our experience, complications involving skin flaps after DC and post-DC cranioplasty cannot be considered a minor event because of their potential to further compromise the yet fragile conditions of these patients. Their management is complex and requires a multidisciplinary approach to get the better results.

Information decay and enzymatic information recovery for DNA data storage (2022)

Synthetic DNA has been proposed as a storage medium for digital information due to its high theoretical storage density and anticipated long storage horizons. However, under all ambient storage conditions, DNA undergoes a slow chemical decay process resulting in nicked (broken) DNA strands, and the information stored in these strands is no longer readable. In this work we design an enzymatic repair procedure, which is applicable to the DNA pool prior to readout and can partially reverse the damage. Through a chemical understanding of the decay process, an overhang at the 3' end of the damaged site is identified as obstructive to repair via the base excision-repair (BER) mechanism. The obstruction can be removed via the enzyme apurinic/apyrimidinic endonuclease I (APE1), thereby enabling repair of hydrolytically damaged DNA via Bst polymerase and Taq ligase. Simulations of damage and repair reveal the benefit of the enzymatic repair step for DNA data storage, especially when data is stored in DNA at high storage densities (=low physical redundancy) and for long time durations.
A Raman scattering study of the helix-destabilizing gene-5 protein with adenine-containing nucleotides (1987)

Raman spectra of gp5 and complexes of gp5 with poly(rA) and poly(dA) have been determined and analysed. From a fit of the amide I-band with model spectra it follows that the secondary structure of gp5 contains 52% beta-sheet, 28% undefined conformation and 19% alpha-helix. The band at 1032 cm-1 due to phenylalanine has an anomalous intensity both in the spectra of the complexes and the free protein. This possibly indicates a stacked structure present in the protein. Binding of gp5 to poly(rA) and poly(dA) influences the intensity of bands near 1338 and 1480 cm-1 which are considered to be marker-bands for the phosphate-sugar-base conformer. A change in conformation of the nucleotides is also reflected by vibrations originating in the phosphate- and sugar-residues of the backbone. In the spectrum of complexed poly(rA) the intensity of the conformation sensitive band at 813 cm-1, which is due to the phosphodiester group, is zero. It seems that gp5 forces poly(rA) and poly(dA) to a similar conformation. A marker band for stacking interaction in poly(rA) indicates that stacking interactions in the complex have increased.
Determination of aflatoxins M1, M2, B1, B2, G1 and G2 in peanut by modified QuEChERS method and ultra-high performance liquid chromatography-tandem mass spectrometry (2014)

A suitable method for routine analysis of aflatoxins M1, M2, B1, B2, G1, G2 in peanut by ultra-high performance liquid chromatography-tandem mass spectrometry was developed and validated. The sample preparation was performed using a triple partitioning (water/acetonitrile/hexane) modified Quick Easy Cheap Effective Rugged and Safe (QuEChERS) method. For the first time, this method is reportedly used for aflatoxins analysis in peanut. Satisfactory recoveries ranged from 71 to 101%, with relative standard deviation lower than 15% were obtained for the target aflatoxins. The determination coefficients were ≥ 0.99 which showed good linearity. The LOD and LOQ varied from 0.03 to 0.26 ng g-1 and 0.1 to 0.88 ng g-1, respectively. The validated method was successfully applied to for the determination of aflatoxins in ten peanut samples. Total aflatoxin concentration exceeded the maximum level permitted by the Brazilian regulation in one sample of roasted peanut, while aflatoxins M1 and M2 were detected respectively in three and in one of the samples. The results strongly suggest that peanuts and peanut products should be continuously monitored for the aflatoxins investigated in this work.
