[Acute intoxication with nutmeg used as a recreational purpose--a case report]. (2013)

We present a case of acute nutmeg poisoning used for recreational purposes. Poisoning had a stormy clinical course with symptoms of gastrointestinal, cardiovascular and nervous system. The widespread availability of nutmeg suggests that real number of these poisonings may be underestimated in our country.
Implementation of virtual network function chaining through segment routing in a linux-based NFV infrastructure (2017)

This paper presents an architecture to support Vir- tual Network Functions (VNFs) chaining using the IPv6 Segment Routing (SR) network programming model. Two classes of VNFs are considered: SR-aware and SR-unaware. The operations to support both SR-aware and SR-unaware VNFs are described at an architectural level and we propose a solution for SR-unaware VNFs hosted in a NFV node. An Open Source implementation of the proposed solution for a Linux based NFV host is available and a set of performance measurements have been carried out in a testbed.
Bearing cage telemeter for the detection of shaft imbalance in rotating systems (2010)

We demonstrate for the first time a low-cost battery-free wireless telemeter integrated on a dynamically balanced ball bearing operating in a test setup that mimics the operating conditions of a two-compressor turbocharger. In this method we continuously monitor the bearing cage temperature and demonstrate the ability to detect rotor imbalance during operation even at low speeds below 5,550 RPM. The telemeter is based on a simple commercially-available temperature-sensitive capacitor coupled with an inductor that is mounted on the bearing cage and is able to operate at temperatures up to 150°C. Cage temperature is sensed wirelessly through a matched interrogator tuned to the natural frequency of the cage sensor at 13.1 MHz. A 5°C temperature differential is detected at 4,700 RPM between a balanced rotor and one with an applied 2.32 × 10 <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">-3</sup> kg-m imbalance.
SCCA1–IGM and SCCA2–IGM Compared with Total SCCA-IGM for Diagnosis of Hepatocellular Carcinoma (2009)

Introduction SCCA1 and SCCA2 belong to the family of serine protease inhibitors (SERPIN). Both SCCA isoforms have been found to be increased in patients with squamous cell carcinoma (SCC) of different organs. Recent findings have demonstrated that SCCA-IgM immune complexes are a novel class of biomarkers for primary liver cancer detection. An increase in SCCA-IgM levels in patients with cirrhosis is associated with the development of liver cancer. Aims and methods To evaluate the diagnostic accuracy of different isoforms of SCCA-IgM compared with a commercial assay for SCCA-IgM in patients with hepatocellular carcinoma (HCC). Twenty-six patients with HCC (M/F 1 9/7; mean age ± SD: 65 ± 13 years) were analyzed. Serum samples from 28 blood donors (M/F 17/11; mean age ± SD: 38 ± 9 years) were used as control. Two monoclonal antibodies, SCC 111 and SCC 1 04 (CanAg Diagnostics, Gothenburg, Sweden) were used as catcher antibodies to perform specific ELISA for SCCA1-lgM and SCCA2-lgM. SCCA-IgM immune complexes were also detected in serum by a commercial ELISA kit (Hepa-IC, Xeptagen, Marghera, Italy) according to the manufacturer's instructions. Results Circulating SCCA1-IgM was detectable in 6 out of 26 patients (sensitivity 23%), while SCCA2-lgM ELISA was positive in 9 of 26 patients (sensitivity 35%). When SCCA-IgM levels were measured using the commercial assay the diagnostic sensitivity increased to 58% (15/26). The SCCA1-IgM, SCCA2-lgM and SCCA-IgM tests had 100% specificity in healthy controls. Conclusions The commercial assay allowed the detection of both isoforms of SCCA forming the IgM immune complexes, providing a better diagnostic sensitivity score than that obtained with the SCCA1-IgM or SCCA2-lgM test.
Emerging patterns of diffusion-weighted MR imaging in Creutzfeldt-Jakob disease: case report and review of the literature. (2002)

We report the use of diffusion-weighted MR imaging in the early diagnosis and monitoring of the progression of a histopathologically proved case of sporadic Creutzfeldt-Jakob disease. Ribbon-like areas of hyperintensity in the cerebral cortex on diffusion-weighted images corresponded to the localization of periodic sharp-wave complexes on the electroencephalogram.
“Mirror, Mirror on the Wall”… Pediatric liver transplantation in the case of situs inversus totalis with a disrupted inferior vena cava (2018)

We present the unique case of a 15-month-old male born with biliary atresia and situs inversus totalis and disrupted inferior vena cava who underwent a successful liver transplantation. The patient had previously undergone a failed Kasai procedure and presented with persistent hyperbilirubinemia. The patient was transplanted with a left lateral segment donor having standard arterial anatomy. Technical considerations included identifying completely replaced arterial anatomy in the recipient from the superior mesenteric artery and creating a branch patch between the gastroduodenal artery and HA, anastomosing the donor left hepatic vein to confluences of the donor left, middle, and right hepatic veins, using a "lazy-S" configuration of portal vein anastomosis, and suspending the allograft to the abdominal wall. Post-operatively, his liver function tests and total bilirubin normalized and he progressed to tolerating an oral diet with tube-feed supplementation.
Complete and efficient methods for supporting side effects in independent/restricted and-parallelism (1989)

It has been shown that it is possible to exploit Independent/Restricted And-parallelism in logic programs while retaining the conventional "don't know" semantics of such programs. In particular, it is possible to parallelize pure Prolog programs while maintaining the semantics of the language. However, when builtin side-effects (such as write or assert) appear in the program, if an identical observable behaviour to that of sequential Prolog implementations is to be preserved, such side-effects have to be properly sequenced. Previously proposed solutions to this problem are either incomplete (lacking, for example, backtracking semantics) or they force sequentialization of significant portions of the execution graph which could otherwise run in parallel. In this paper a series of side-effect synchronization methods are proposed which incur lower overhead and allow more parallelism than those previously proposed. Most importantly, and unlike previous proposals, they have well-defined backward execution behaviour and require only a small modification to a given (And-parallel) Prolog implementation.

Ceramic Materials having Strain Sensing Properties -The CaO-NiO Ceramics- (1999)

The strain sensing properties of the system xNiO-(1-x)CaO with various compositions (x=0.001-0.05) are evaluated and the origin of the phenomena is guessed. We have found out that the high temperature electrical conductivity of the xNiO-(1-x)CaO increases by applying the compressive stress at 1000℃. When the applied load is removed, the electrical conductivity rapidly decreases and returns to the original value, but a small hysteresis of the stress-conductivity curve is observed. After the loading test, the lattice parameter of the specimen is found lengthened. The correlation between the lengthening of the lattice parameter and the increase in the electrical conductivity by loading is discussed. The amount of the expanded type Ni(Ⅱ)O6 clusters in the xNiO-(1-x)CaO grains is supposed to be increased by the applied stress, which would be the origin of the strain dependent electric conduction in the xNiO-(1-x)CaO system.
Abiotic Stress (2007)

Abstract Plants, being sessile organisms, are exposed to external factors that can be stressful in such a way that growth, development, and reproduction or the yield of crops become compromised. Expanding extensive physiological studies, the last decade has seen a focus on genes and biochemical pathways that determine whether plants are sensitive or tolerant to the many different stress factors: heat, cold and freezing, drought, salinity, flooding or oxidizing agents. Recently, most emphasis is being directed towards an understanding of the mechanisms through which plants recognize external conditions, and on the signailing pathways that initiate protective reactions.
Dense Self‐Assembly on Sparse Chemical Patterns: Rectifying and Multiplying Lithographic Patterns Using Block Copolymers (2008)

A lithography-friendly self-assembly process which multiplies and rectifies an existing resist patterns is demonstrated here. A polymer film (right figure) has assembled at a 14 nm half-pitch on a thin resist pattern at twice the period (left figure). This directed self-assembly process dramatically heals defects and reduces feature size variation of the ill-defined resist patterns.
Practical methods for minimizing embedding impact in steganography (2007)

In this paper, we propose a general framework and practical coding methods for constructing steganographic schemes that minimize the statistical impact of embedding. By associating a cost of an embedding change with every element of the cover, we first derive bounds on the minimum theoretically achievable embedding impact and then propose a framework to achieve it in practice. The method is based on syndrome codes with low-density generator matrices (LDGM). The problem of optimally encoding a message (e.g., with the smallest embedding impact) requires a binary quantizer that performs near the rate-distortion bound. We implement this quantizer using LDGM codes with a survey propagation message-passing algorithm. Since LDGM codes are guaranteed to achieve the rate-distortion bound, the proposed methods are guaranteed to achieve the minimal embedding impact (maximal embedding efficiency). We provide detailed technical description of the method for practitioners and demonstrate its performance on matrix embedding.
Solid phase epitaxial growth of high mobility La:BaSnO3 thin films co-doped with interstitial hydrogen (2016)

This work presents the solid phase epitaxial growth of high mobility La:BaSnO3 thin films on SrTiO3 single crystal substrates by crystallization through thermal annealing of nanocrystalline thin films prepared by pulsed laser deposition at room temperature. The La:BaSnO3 thin films show high epitaxial quality and Hall mobilities up to 26 ± 1 cm2/Vs. Secondary ion mass spectroscopy is used to determine the La concentration profile in the La:BaSnO3 thin films, and a 9%–16% La doping activation efficiency is obtained. An investigation of H doping to BaSnO3 thin films is presented employing H plasma treatment at room temperature. Carrier concentrations in previously insulating BaSnO3 thin films were increased to 3 × 1019 cm−3 and in La:BaSnO3 thin films from 6 × 1019 cm−3 to 1.5 × 1020 cm−3, supporting a theoretical prediction that interstitial H serves as an excellent n-type dopant. An analysis of the free electron absorption by infrared spectroscopy yields a small (H,La):BaSnO3 electron effective mass of 0.27 ± 0.05 m0 and an optical mobility of 26 ± 7 cm2/Vs. As compared to La:BaSnO3 single crystals, the smaller electron mobility in epitaxial thin films grown on SrTiO3 substrates is ascribed to threading dislocations as observed in high resolution transmission electron micrographs.
Investigation of the spatial structure of a cyclic analog of bradykinin in solution by two-dimensional NMR spectroscopy (1986)

Assignment of the /sup 1/H NMR signals of (cyclo(9 ..-->.. 1/sup epsilon/), Lys/sup 1/, Gly/sup 6/)bradykinin (CBK) in (CD/sub 3/)/sub 2/SO and H/sub 2/O has been made by the combined analysis of two-dimensional COSY and NOESY spectra. It has been shown that in (CD/sub 3/)/sub 2/SO solution there are two slowly interchanging conformers of CBK; the amount of the minor conformer does not exceed 15%. In aqueous solution the minor conformer is absent, and the chemical shifts of the NH and Csup..cap alpha..H protons of CBK and of the natural peptide differ insignificantly. Models are proposed of the spatial structure of the backbone of fragments 6-9 of CBK, which contain two intramolecular hydrogen bonds with the participation of the NH group of the Arg/sup 9/ residue, the N/sup zeta/H group of the Lys/sup 1/ residue, and the carbonyl groups of the Phe/sup 5/ and Gly/sup 6/ residues
Towards Object-Oriented Modeling of Complex Mechatronic Systems for the Manufacturing Industry (2006)

The advantages of object-oriented modeling, as modularity and reusability of components, are very important also for modeling manufacturing systems and not only for software development. In [1] a unified object-oriented approach for modeling both the logical and the physical part of a manufacturing machine has been proposed. In this paper we report an industrial application of this modeling strategy and the case study consists of the package forming unit of a filling machine for liquid food packaging, developed by Tetra Pak Carton Ambient S.p.a.
Risk Factors for Screen-Detected Breast cancer a case-control study (1992)

Risk factors for breast cancer (BC) detected in mammography screening were sought using a questionnaire among 31,927 women aged from 40 to 74 years who attended screening. Data from 204 women with screen-detected BC were compared with those of 612 controls who did not have BC in screening. Mothers of women with BC had more often BC than those of the controls (8% vs. 3%, odds ratio, OR, 3.18, 95% CI 1.59-6.35). Women with screen-detected BC were older at their first childbirth (25.7 years vs. 24.7 years, OR 1.61, 1.14-2.33), and younger at menarche (13.6 years vs. 13.8 years, OR 1.38, 1.00-1.91), but there was no significant difference in the body mass index, number of pregnancies, breast size, smoking, or in the use of contraceptive pills between the cases and the controls. In multivariate logistic regression analyses, late age at the first childbirth, BC in the mother, and early age at menarche were independent risk factors for screen-detected BC but they appear to be of limited value in targeting screening in the female population aged from 40 to 74 in order to improve its cost-effectiveness.

Efficient Circuits for Quantum Search over 2D Square Lattice Architecture (2019)

Quantum computing has increasingly drawn interest and investments from the academic, industrial, and governmental research communities worldwide. Among quantum algorithms, Quantum Search is important for its quadratic speedup over its classical-computing counterpart. A key ingredient in its implementation is the Multi-Control Toffoli (MCT) gate, which creates a Boolean product of control variables and XORs it into the target. On an idealized quantum computer, all-to-all connectivity would eliminate the need to use SWAP gates to communicate information. This is, however, not affordable in the current Noisy Intermediate-Scale Quantum (NISQ) computing era. In this work, we discuss how to efficiently implement MCT gates on 2D Square Lattices (2DSL), suitable for superconducting circuits, by taking advantage of relative-phase Toffoli gates and H-tree layouts to drastically reduce resulting circuits' depths and the amount of SWAPping required.
High-Dose Fluorescein Reveals Unusual Confocal Endomicroscope Imaging of Low-Grade Glioma (2021)

<b>Background:</b> Fluorescence-guided brain tumor surgery using fluorescein sodium (FNa) for contrast is effective in high-grade gliomas. However, the effectiveness of this technique for visualizing noncontrast-enhancing and low-grade gliomas is unknown. This report is the first documented case of the concurrent use of wide-field fluorescence-guided surgery and confocal laser endomicroscopy (CLE) with high-dose FNa (40 mg/kg) for intraoperative visualization of tumor tissue cellularity in a nonenhancing glioma. <b>Case Description:</b> A patient underwent fluorescence-guided surgery for a left frontal lobe mass without contrast enhancement on magnetic resonance imaging. The patient received 40 mg/kg FNa intravenously at the induction of anesthesia. Surgery was performed under visualization with a Yellow 560 filter and white-light wide-field imaging. Intraoperative CLE produced high-quality images of the lesion 1.5 h after FNa injection. Frozen-section analysis demonstrated findings comparable to those of intraoperative CLE visualization and consistent with World Health Organization (WHO) glioma grades II-III. The patient recovered without complications. Analysis of the permanent histologic sections identified the tumor as an anaplastic oligodendroglioma, IDH-mutant, 1p/19q co-deleted, consistent with WHO grade III because of discrete foci of hypercellularity and increased mitotic figures, but large regions of the lesion were low grade. <b>Conclusions:</b> The use of high-dose FNa in this patient with a nonenhancing borderline low-grade/high-grade glioma produced actionable wide-field fluorescence imaging using the operating microscope and improved CLE visualization of tumor cellularity. Higher doses of FNa for intraoperative CLE imaging and possible simultaneous wide-field fluorescence surgical guidance in nonenhancing gliomas merit further investigation.
Detection for a statistically known, time-varying dispersive channel (1996)

Detection for the statistically known channel (SKC) is aimed at obtaining good performance in situations where our statistical knowledge of a time-varying channel is good, and where other equalization/detection schemes are either too complex to implement, or their performance is limited due to the rapidity of channel fading, or where we are simply unable to perform channel estimation. By using a statistical characterization of the channel, we develop a new detector that performs maximum-likelihood sequence estimation (MLSE) (given the channel model) on blocks of N symbols. Both symbol-spaced and fractionally spaced samples are used, to obtain two different detectors, that are generalizations of those devised for optimal block schemes on nondispersive channels. The detector that uses fractionally spaced samples is shown to outperform the detector that uses symbol-spaced samples. The performance of both appears to approach that of the corresponding known channel (KC) detector as the block length increases. We also numerically evaluate the SKC detector performance under conditions where the channel parameters (statistics) are incorrectly estimated, and show that the fractionally spaced detector is fairly robust to modeling errors. Finally, we devise a sliding block algorithm, for use when transmitting more than N symbols.
Stochastic vagus nerve stimulation affects acute heart rate dynamics in rats (2018)

Vagus nerve stimulation (VNS) is an approved therapy for treatment of epilepsy and depression. While also shown to be promising in several preclinical and clinical studies to treat cardiovascular diseases, optimal therapeutic stimulation paradigms are still under investigation. Traditionally, parameters such as frequency, current, and duty cycle are used to adjust the efficacy of VNS therapy. This study explored the effect of novel stochastic VNS (S-VNS) on acute heart rate (HR) dynamics. The effect of S-VNS was evaluated in Sprague Dawley rats by comparing the acute HR and HR variability (HRV) responses to standard, periodic VNS (P-VNS) across different frequencies (FREQs, 10-30 Hz). Our results demonstrate that both S-VNS and P-VNS produced negative chronotropic effects in a FREQ-dependent manner with S-VNS inducing a significantly smaller drop in HR at 10 Hz and 20 Hz compared to P-VNS (p<0.05). S-VNS demonstrated a FREQ-dependent drop in the SD1/SD2 ratio, a measure of HRV, which was absent in P-VNS, suggesting that S-VNS may acutely modulate the nonlinear relationship between short- and long-term HRV. In conclusion, S-VNS is a novel stimulation procedure that may provide different physiological outcomes from standard P-VNS, as indicated by our analysis of HR dynamics. Our study provides a rationale for further detailed investigations into the therapeutic potential of S-VNS as a novel neuromodulation technique.
Motion Sensorless Bidirectional PWM Converter Control with Seamless Switching from Power Grid to Stand Alone and Back (2007)

This paper presents concepts and tests results on a flexible sensorless control strategy for a PMSG driven by a small wind turbine with back-to-back power converters capable to function in both stand alone and grid connection mode. A new automatic seamless transfer method, based on phase-locked-loop technique, from grid connected to stand alone and vice versa in the event of a fault on grid is proposed. Tests results show the proposed method works properly
EFFICIENT OPTIMIZATION ALGORITHMS FOR LEARNING (2003)

Many problems in machine learning and pattern recognition ultimately reduce to the optimization of a scalar valued function. A variety of general techniques exist for optimizing such objective functions. We study the general class of bound optimization algorithms—including Expectation-Maximization, Iterative Scaling, Non-negative Matrix Factorization, Concave-Convex Procedure—and their relationship to direct optimization algorithms such as gradient-based methods for parameter learning. We also provide a theoretical analysis of the convergence properties of bound optimization algorithms and identify analytic conditions under which these optimizers exhibit quasi-Newton behavior, and conditions under which they possess poor, first-order convergence. Motivated by these analyses, we interpret and analyze their convergence properties and provide some recipes for preprocessing input to these algorithms to yield faster convergence behavior. Our presented analysis also allows us to design several algorithms for practical optimization, that possess superior convergence over standard existing methods.
