Prediction of giant magneto-impedance effect in amorphous glass-coated micro-wires using artificial neural network Proceedings of the International Congress in Honour of Professor Hari M. Srivastava
No full textThis paper deals with a prediction of a giant magneto-impedance (GMI) effect on amorphous micro-wires using an artificial neural network (ANN). The prediction model has three hidden layers with fifteen neurons and full connectivity between them. The ANN model is used to predict the GMI effect for Co70.3Fe3.7B10Si13Cr3 glass-coated micro-wire. The results show that the ANN model has a 98.99% correlation with experimental data. © 2013 Kaya; licensee Springer
The Problem of Mental Causation in John Searle's Theory of Consciousness
No full textSome philosophers of mind claim that non-reductionist physicalist theories of the mind cannot explain the causal interaction between consciousness and the physical world. The problem is about explaining how consciousness, which cannot be reduced to physical processes, interacts with the physical world without violating the laws of physics. John Searle claims to have solved the problem of mental causation in his theory of mind, which he calls Biological Naturalism, exhibiting a non-reductionist attitude. In this study, I aim to evaluate Searle's solution to the problem of mental causation. For this purpose, I will first touch on mental causation and how it is understood. Then, I will outline the problem and address the specific criticisms against non-reductionist physicalists. Finally, considering these criticisms, I will show under what conditions Searle's solution to the problem of mental causation can be accepted as correct.WOS:00093391120000
The Importance of Propionibacterium acnes Place in Microbiology World
No full textPropionibacterium acnes is most commonly recognized for its acne pathogenesis. However, it is known that P. acnes produces chemotactic substances and activates the compleman system. Recently, it has also been shown to take an important place in the pathogenesis of other diseases and exhibit opportunistic pathogenic properties with increased number of molecular studies. In addition, various studies have been carried out in order to use its effects on the immunity for therapeutic purposes. In this review, the features and pathogenesis of P. acnes have been reviewed in the light of current literature

Pain Management in Minimally Invasive Cardiac Surgery: A Review of Current Clinical Evidence
No full textAbstract Compared with conventional sternotomy, minimally invasive cardiac surgery (MICS) is associated with significant advantages such as reduced tissue trauma, faster recovery, and shorter hospital stay. However, the management of postoperative pain caused by intercostal nerve injury, pleural irritation, and tissue retraction remains a major challenge. Despite the less invasive nature of MICS, patients often report experiencing pain similar to that experienced following conventional cardiac surgery, particularly during the acute postoperative period. Effective pain management is essential for optimizing recovery, reducing the consumption of opioids, and preventing the transition to chronic postsurgical pain. Regional anesthesia techniques play a key role in multimodal analgesia for MICS. Thoracic epidural analgesia exhibits strong analgesic efficacy; nevertheless, it remains underutilized owing to concerns regarding anticoagulation-related complications and hemodynamic instability. The thoracic paravertebral block is a safer alternative that provides comparable pain relief with fewer side effects. Similarly, ultrasound-guided fascial plane blocks, such as serratus anterior, parasternal intercostal, interpectoral + pectoserratus, and erector spinae plane blocks, have gained popularity owing to their safety and feasibility; however, the effectiveness of these blocks varies according to the surgical approach and type of incision. Systemic analgesia is an integral component of multimodal pain management in MICS. Despite the efficacy of opioids, a shift toward opioid-sparing strategies has been observed given the significant adverse effects associated with the use of opioids. Intravenous adjuncts such as dexmedetomidine, ketamine, and non-steroidal anti-inflammatory drugs can reduce opioid consumption and improve postoperative pain control. Despite advances in pain management, a single approach that can provide comprehensive analgesia for MICS remains to be established. A multimodal strategy that combines systemic and regional techniques must be developed to optimize pain management and long-term outcomes
The development of financial services and financial regulation in Angola

Regulatory tradeoffs in designing concession contracts for infrastructure networks
Get PDFNetwork activities typically involve collecting a good or service (such as electric utilities, phone services, and rail transportation) from many producers or distributing them to many users. Producers and users are often widely scattered, geographically. Close financial integration of networks is justified on the basis of economies of scope and scale and the benefits from pooling and coordinating. In many countries, network operators are completely integrated publicly-owned firms (private firms being deemed insufficiently efficient or equitable). Challengers of this practice contend that the inefficiency resulting from lack of competition outweighs the gain from economic integration. With reform, some competitive mechanisms can be introduced even when monopoly seems the best option for delivering a service. But conflicts between policymakers'objectives -including efficiency, equity, speed, speed of reform, and signaling- influence the design of concession contracts for infrastructure network services (including communications and transportation services). Competition begins with the unbundling of various stages of delivery. Then competitive bidding is popular, with the public authority keeping property rights on productive assets but conceding their operation to a private firm. The winner gets the right to maximize profits, within limits (having to provide universal services, for example, and avoid price discrimination). In liberalizing the delivery of a service, policymakers must consider not only efficiency but also social and fiscal feasibility. The authors discuss how relevant information asymmetry is in contract design and the award and regulatory processes. They also discuss how to design pricing to accommodate the obligation to provide universal service. To illustrate, they describe Argentina's experiment in liberalization, which is increasingly viewed as a model for changing private sector and government involvement in infrastructure services. Beginning in 1989, Argentina began privatizing utilities and transport services, because the government had decided that it could no longer afford to subsidize those services or finance the investments needed for their effective operation. To introduce competition, the government unbundled services and introduced competitive bidding. It also created sector-specific regulatory agencies to protect consumers from private monopolies and to protect the private concessionaires from government micromanagement. Making concession-based reform and contracted-based regulation of private monopolists sustainable will require strengthening regulatory agencies, clarifying their terms of reference and accountability, and better separating the responsibilities of sector ministers and regulators.Health Economics&Finance,Environmental Economics&Policies,Economic Theory&Research,Labor Policies,International Terrorism&Counterterrorism,Environmental Economics&Policies,Health Economics&Finance,Education for the Knowledge Economy,Knowledge Economy,Economic Theory&Research
Order and disorder in proteins
No full textIn contrast to the general view that proteins should have a specific 3D structure in solution for their activity, there are many proteins which do not have a folded “native” structure for a big portion of their sequence. While these intrinsically disordered regions are essential for protein function, they cause problems in efforts for determining the 3D structures for the folded domains. It has been shown that the removal of the disordered domains improved the structure determination success both by X-ray crystallography and by NMR. As part of Northeast Structural Genomics (NESG) effort I worked on identifying the disordered and flexible parts of the protein using Hydrogen/Deuterium Exchange with Mass Spectroscopy (HDX-MS) analysis for construct optimization for high-throughput structure determination. Using this method I also studied human Smad3, which is an important part of the TGF-β-signaling pathway; and provided the first experimental data on structural features of the linker domain. During my training, I also studied human Deleted in Oral Cancer (DOC-1) protein, which was one of the proteins I studied by HDX-MS for construct optimization. We determined the solution structure of the folded region of DOC-1, which was shown to be important in cell-cycle regulation and cancer biology; and I also studied structure-function relations. Additionally, we studied the solution structure of Methionine Sulfoxide Reductase B from Bacillus subtilis, an important protein for reversing oxidative damage in cells, by NMR as a part of methods development studies for NMR for large proteins.Ph.
