Braiding of Abelian and Non-Abelian Anyons in the Fractional Quantum Hall Effect (2011)

In this paper, we report on the study of Abelian and non-Abelian statistics through Fabry-Perot interferometry of fractional quantum Hall (FQH) systems. Our detection of phase slips in quantum interference experiments demonstrates a powerful, new way of detecting braiding of anyons. We confirm the Abelian anyonic braiding statistics in the $ν= 7/3$ FQH state through detection of the predicted statistical phase angle of $2π/3$, consistent with a change of the anyonic particle number by one. The $ν= 5/2$ FQH state is theoretically believed to harbor non-Abelian anyons which are Majorana, meaning that each pair of quasiparticles contain a neutral fermion orbital which can be occupied or unoccupied and hence can act as a qubit. In this case our observed statistical phase slips agree with a theoretical model where the Majoranas are strongly coupled to each other, and strongly coupled to the edge modes of the interferometer. In particular, an observed phase slip of approximately $π$ is interpreted as a sudden flip of a qubit, or entry of a neutral fermion into the interferometer. Our results provide compelling support for the existence of non-Abelian anyons.

Nanostructuring of Patterned Microelectrodes To Enhance the Sensitivity of Electrochemical Nucleic Acids Detection (2009)

Take the rough without the smooth: The electrodeposition of patterned metal microelectrodes on a chip-based platform led to biosensors with varying sensitivity according to the degree of surface nanostructuring, which could be controlled systematically (see picture). The sensitivity of microelectrodes with highly nanostructured surfaces was superior to that of smooth microelectrodes.

Photodegradation in Ballistic Laminates: Spectroscopy and Lifetime Extension* (1997)

Polycarbonate (PC), a critical component in ballistic laminates (BLs), is known to degrade upon exposure to ultraviolet (UV) light. For the purpose of reducing the photodegradation, a UV blocking chemical has been added to the adhesives used to join the layers of the BL. This report describes the development of a spectroscopic method for monitoring surface photodegradation of PC and the method's use in demonstrating the effectiveness of the UV blocker. Reports in the literature demonstrate that photodegradation in thin PC films may be detected by transmission infrared (IR) spectroscopy. The present work extends this approach to thick films, where small surface changes are detected by reflectance IR spectroscopy. We show that UV photodegradation of the PC surface produces a characteristic shift in the carbonyl absorption band at about 1775 cm −1 . This shift is consistently observed in PC samples that have been subjected to direct artificial exposure and in PC samples that have been subjected through the outboard layers of the BL to both natural and artificial exposure. When a UV blocker is incorporated into the adhesive layers of the laminate, no peak shift is observed in the carbonyl band after the equivalent of 10 years of exposure.
Adaptation of failure scenario based resilience schemes toward availability guarantees (2006)

Feature Issue on High Availability in Optical NetworksVarious resilience schemes have been proposed to allow for fault-tolerant transport networks. Their common aim is to survive certain failure patterns such as node or span failures by providing alternative transmission paths. However, network operators guarantee the resulting network reliability in terms of service availability to their business customers. A maximum duration of service disruption per year must not be exceeded. We investigate an optimal design of resilient network configurations that adapts to end-to-end availability requirements. We formulate an integer linear program that minimizes the resource utilization and investigate a case study.
Periprocedural Changes of NT‐proBNP Are Associated With Survival After Transcatheter Aortic Valve Implantation (2019)

Background Cardiovascular biomarkers constitute promising tools for improved risk stratification and prediction of outcome in patients undergoing transcatheter aortic valve implantation. We examined the association of periprocedural changes of NT-proBNP (N-terminal pro-B-type natriuretic peptide) with survival after transcatheter aortic valve implantation. Methods and Results NT-proBNP levels were measured in 704 patients before transcatheter aortic valve implantation and at discharge. Patients were grouped as responders and nonresponders depending on an NT-proBNP-based ratio (postprocedural NT-proBNP at discharge/preprocedural NT-proBNP). Overall, 376 of 704 patients showed a postprocedural decrease in NT-proBNP levels (NT-proBNP ratio <1). Responders and nonresponders differed significantly regarding median preprocedural (2822 versus 1187 pg/mL, P<0.001) and postprocedural (1258 versus 3009 pg/mL, P<0.001) NT-proBNP levels. Patients in the nonresponder group showed higher prevalence of atrial fibrillation (47.0% versus 39.4%, P=0.042), arterial hypertension (94.2% versus 87.5%, P=0.002), renal impairment (77.4% versus 69.1%, P=0.013), and peripheral artery disease (24.4% versus 14.6%, P=0.001). In contrast, patients in the responder group had higher prevalence of moderately reduced left ventricular ejection fraction (17.3% versus 11.0%, P=0.017), lower calculated aortic valve area (0.7 versus 0.8 cm<sup>2</sup>, P<0.001), and higher mean pressure gradient (41 versus 35 mm Hg, P<0.001). Median follow-up was 22.6 months. Kaplan-Meier analysis showed a highly significant survival benefit for the responder group compared with the nonresponder group (log-rank test, P<0.001). Conclusions A ratio based on periprocedural changes of NT-proBNP is a simple tool for better risk stratification and is associated with survival in patients after transcatheter aortic valve implantation.
Nuclear Factor-κB Dimer Exchange Promotes a p21waf1/cip1 Superinduction Response in Human T Leukemic Cells (2006)

The nuclear factor-kappaB (NF-kappaB)/Rel transcription factors are recognized as critical apoptosis regulators. We reported previously that NF-kappaB contributes to chemoresistance of CEM human T leukemic cells in part through its ability to induce p21(waf1/cip1). Here, we provide evidence that sequential NF-kappaB-activating signals induce heightened NF-kappaB DNA binding and p21(waf1/cip1) induction in CEM and additional T leukemic cell lines. This response arises from exceedingly low basal expression of the p105/p50 NF-kappaB subunit encoded by the NFKB1 gene in these cell lines. An initial NF-kappaB activation event enhances the recruitment of p65 and ELF1 to the NFKB1 promoter, leading to p65- and ELF1-dependent synthesis of p105/p50, which promotes an exchange of NF-kappaB complexes to p50-containing complexes with an increased DNA-binding activity to certain NF-kappaB target elements. Subsequent stimulation of these cells with an anticancer agent, etoposide, results in augmented NF-kappaB-dependent p21(waf1/cip1) induction and increased chemoresistance of the leukemia cells. Thus, we propose that low basal NFKB1 expression coupled with sequential NF-kappaB activation events can promote increased chemoresistance in certain T leukemic cells.
Recent Advances in Rechargeable Magnesium Battery Technology: A Review of the Field’s Current Status and Prospects (2015)

Abstract The demand for new energy storage systems to be employed in large‐scale electrical energy storage systems (EESs) has grown recently, particularly for green energy storage and grid‐supporting applications. Rechargeable Mg batteries are promising candidates for such applications because of their good safety characteristics and raw materials’ abundance. Recent progress in the field is noticeable, but further efforts are required to support the successful implementation of rechargeable Mg batteries. We address progress in the development of rechargeable Mg batteries and problems to be resolved in future research, briefly summarize the most recent advances in the development of rechargeable Mg batteries, from a materials perspective, and cover progress on each of the major components of Mg batteries: the electrolyte, the cathode material, and the anode material. We provide a practical guideline for further development of self‐sustainable rechargeable Mg batteries as a future power source.
Insights on the Hypoglycemic Potential of Crocus sativus Tepal Polyphenols: An In Vitro and In Silico Study (2023)

Post-prandial hyperglycemia typical of diabetes mellitus could be alleviated using plant-derived compounds such as polyphenols, which could influence the activities of enzymes involved in carbohydrate digestion and of intestinal glucose transporters. Here, we report on the potential anti-hyperglycemic effect of <i>Crocus sativus</i> tepals compared to stigmas, within the framework of valorizing these by-products of the saffron industry, since the anti-diabetic properties of saffron are well-known, but not those of its tepals. In vitro assays showed that tepal extracts (TE) had a greater inhibitory action than stigma extracts (SE) on α-amylase activity (IC50: TE = 0.60 ± 0.09 mg/mL; SE = 1.10 ± 0.08 mg/mL; acarbose = 0.051 ± 0.07) and on glucose absorption in Caco-2 differentiated cells (TE = 1.20 ± 0.02 mg/mL; SE = 2.30 ± 0.02 mg/mL; phlorizin = 0.23 ± 0.01). Virtual screening performed with principal compounds from stigma and tepals of <i>C. sativus</i> and human pancreatic α-amylase, glucose transporter 2 (GLUT2) and sodium glucose co-transporter-1 (SGLT1) were validated via molecular docking, e.g., for human pancreatic α-amylase, epicatechin 3-o-gallate and catechin-3-o-gallate were the best scored ligands from tepals (-9.5 kcal/mol and -9.4 kcal/mol, respectively), while sesamin and episesamin were the best scored ones from stigmas (-10.1 kcal/mol). Overall, the results point to the potential of <i>C. sativus</i> tepal extracts in the prevention/management of diabetes, likely due to the rich pool of phytocompounds characterized using high-resolution mass spectrometry, some of which are capable of binding and interacting with proteins involved in starch digestion and intestinal glucose transport.
Synthesis and Magnetic Properties of SrO2FeO8Fe2O3 W-type Hexagonal Ferrite. (1997)

As W-type hexagonal ferrite permanent magnets with the formula SrO⋅2FeO⋅8Fe2O3 contain both ferrous and ferric oxides, a complicated atmosphere control during the sintering process is necessary in manufacturing, which is impractical for industrial production. Thus, a simple manufacturing method which is characterized by employing a combination of the addition of carbon and the adoption of nitrogen atmosphere in sintering was investigated, so that high performance permanent magnets were successfully prepared. It was found that the additional amount of carbon and the heating temperature for drying green body are closely associated with oxidation and reduction in the sintering process. The unfitted conditions for synthesis are apt to produce extra phase, such as hematite and magnetite which influence magnetic properties. Especially, small amounts of magnetite which are produced by a reduction phenomenon during the sintering process decrease coercivity remarkably. A pure W-phase was formed by addition of 0.2wt% carbon and drying green body at 200°C for 3h. The highest magnetic properties obtained by the present work are remanence of 0.48T (4.8kG), coercivity of 200kA/m (2.5kOe) and the maximum energy product of 42kJ/m3 (5.3MGOe).
Stable low-stress tungsten absorber technology for sub-half-micron x-ray lithography (1991)

Tungsten is attractive for very large scale integrated device metallization and as absorber for x-ray lithographic masks. To minimize distortions in an x-ray mask, intrinsic stresses in the absorber films have to be low and reproducible. We present the results of a systematic study of the microstructure and stress of rf sputter-deposited W films as a function of deposition parameters, using optical interferometry, scanning electron microscopy, transmission electron microscopy, and x-ray diffraction. Rutherford backscattering spectrometry and Auger electron spectroscopy were used for the chemical analysis of the films. By controlling the nucleating phase and mobility of the adatoms, we have produced W films with low stresses (&amp;lt;±50 MPa). The low-stress films have a 〈110〉 preferred orientation and a bimodal grain size distribution with large, elongated grains surrounded by small equiaxed grains. The lattice parameter and the argon content in W films increased with decreasing argon deposition pressure. It was found that a low base pressure (&amp;lt;10−7 Torr) is necessary to produce stable α-phase W and to eliminate the metastable β phase. Additional seed layers (Cr, SiO2 ) at the Si/W interface resulted in a small improvement in stress control of the W films. The W films were stable (no change in stress) on subsequent anneals at 200 °C for 50 h in vacuum and argon ambients.
Darstellung, Reaktionen und Strukturen spirobicyclischer Phosphorane (1980)

Abstract Durch Reaktion von trimethylsilyl‐substituierten Harnstoffen mit Dichlorphenylphosphan erhielten wir die spirobicyclischen Phosphorane 1b und 1c mit einer λ 3 P – λ 5 P‐Bindung. Mit Chlor oder PCl 5 reagieren 1a – c unter Eliminierung von Dichlorphenylphosphan zu den spirobicyclischen Verbindungen 2a – c mit zwei gespannten Vierringen. Die Struktur von 2a wurde durch eine Röntgenanalyse belegt. Das Phosphoratom in 2a nimmt nicht die erwartete rechteckigpyramidale Konfiguration ein, sondern hat eine annähernd trigonal‐bipyramidale Geometrie. Die Reaktion des Harnstoffderivats [Si(CH 3 ) 3 ](3‐CF 3 C 6 H 4 )NC(O)N(CH 3 )[Si(CH 3 ) 3 ] mit C 2 F 5 PCl 2 führt zum viergliedrigen Heterocyclus 3 , während die entsprechende Umsetzung mit PCl 3 unter Abspaltung von Carbodiimid den Bicyclus 4 ergibt.
Data from Evaluating a Marker's Contribution to a Nomogram: The GEMCaP Example (2023)

&lt;div&gt;Abstract&lt;p&gt;A postoperative nomogram developed in 1999 by Kattan et al. has been externally validated, but needs improvement. This tool predicts well but not perfectly. The Genomic Evaluators of Metastatic Prostate Cancer (GEMCaP) biomarkers hold promise for improving this tool; however, a larger data set that permits more involved analyses is needed.

Improvement of Endothelial function by Amlodipine and Vitamin C in Essential Hypertension (2002)

Vitamin C (acutely) and amlodipine (chronically) improved endothelial function in hypertensive patients. These results suggest that increased oxidative stress, at least in part, may be involved in the decreased endothelial function in hypertension.
Model-free $H_{\infty}$ Control of Linear Discrete-time Systems using Q-learning and LMI Based on I/O Data (2009)

In this paper, we consider the design of control of linear discrete-time systems having no mathematical model. The basic approach is to use Q-learning which is a reinforcement learning method based on actor-critic structure. The model-free control design is to use not the mathematical model of the system but the informations on states and inputs. As a result, the derived iterative algorithm is expressed as linear matrix inequalities(LMI) of measured data from system states and inputs. It is shown that, for a sufficiently rich enough disturbance, this algorithm converges to the standard control solution obtained using the exact system model. A simple numerical example is given to show the usefulness of our result on practical application.
Electric load forecasting using parallel RBF neural network (2013)

Electric load forecasting plays a critical role for the reliable and efficient operation of power grids. In this paper we propose a load forecasting model using parallel radial basis function neural networks (RBFNN). The proposed implementation of RBFNN allows parallel computation therefore expedites the convergence of training process. The proposed model also employs a new hybrid chaotic genetic algorithm which introduces small scale chaotic variations into the best fit individuals in each iteration to locate an optimal set of parameters in RBFNN. We experiment the proposed load forecasting model with realistic demand data collected from both micro-grid as well as bulk grid levels, i.e., a local institutional micro-grid and one utility in the UK national grid. It is found that both cases can achieve acceptable forecasting accuracy with average error rate smaller than 4%, while forecasting the micro-grid load is more challenging than that of the bulk grid load due to the intermittent fluctuations within the former.
Finite Field Arithmetic for Cryptography (2010)

Cryptography is one of the most prominent application areas of the finite field arithmetic. Almost all public-key cryptographic algorithms including the recent algorithms such as elliptic curve and pairing-based cryptography rely heavily on finite field arithmetic, which needs to be performed efficiently to meet the execution speed and design space constraints. These objectives constitute massive challenges that necessitate interdisciplinary research efforts that will render the best algorithms, architectures, implementations, and design practices. This paper aims to provide a concise perspective on designing architectures for efficient finite field arithmetic for usage in cryptography. We present different architectures, methods and techniques for fast execution of cryptographic operations as well as high utilization of resources in the realization of cryptographic algorithms. While it is difficult to have a complete coverage of all related work, this paper aims to reflect the current trends and important implementation issues of finite field arithmetic in the context of cryptography.
Pretransplantation interferon treatment and recurrence of hepatitis B virus infection after liver transplantation for hepatitis B-related end-stage liver disease (1994)

Orthotopic liver transplantation in patients with hepatitis B-related cirrhosis is commonly complicated by reinfection with the hepatitis B virus, with rapidly progressive liver disease and poor survival rate. We assessed the efficacy of prior therapy with recombinant interferon-alpha on the prevention of posttransplantation hepatitis B virus reinfection. Twenty-two patients with hepatitis B-related cirrhosis waiting for liver transplantation received 3 MU (decreased to 1.5 MU in cases of intolerance) of recombinant interferon-alpha until transplantation. The rates of posttransplantation hepatitis B virus reinfection and survival in this group were compared with those in a group of 26 patients previously given transplants for the same disease but not given interferon therapy. The same protocol of HBs antibody passive immunoprophylaxis was applied after transplantation in both groups. Recombinant interferon-alpha was administered for 14 +/- 7 wk. The treatment had an antiviral effect, with disappearance of serum hepatitis B virus DNA in seven of the eight patients initially positive for hepatitis B virus DNA and disappearance of HBeAg in two of the three patients initially positive for HBeAg. Serum hepatitis B virus DNA remained detectable with polymerase chain reaction at transplantation in 56% of the interferon-treated patients. After transplantation, hepatitis B virus reinfection was more frequent in polymerase chain reaction-positive than in polymerase chain reaction-negative patients (78% vs. 17%, p < 0.05). One patient's condition deteriorated during interferon treatment; this patient was not given a transplant. Two patients (in whom hepatitis B virus DNA disappeared from serum) improved so markedly during treatment that they were not given transplants.(ABSTRACT TRUNCATED AT 250 WORDS)
