Combining cyclosporin with chemotherapy controls intraocular retinoblastoma without requiring radiation. (1996)

Chemotherapy without radiation has not controlled most intraocular retinoblastoma, perhaps because of the common high expression of multidrug resistance P-glycoprotein that we found in retinoblastoma. Cyclosporin blocks P-glycoprotein-induced efflux of vincristine and teniposide in vitro, and possibly modulates responses to carboplatin. To avoid eye irradiation in bilateral retinoblastoma patients with RB1 germline mutations, which incurs a high second malignancy rate, we added cyclosporin A to a vincristine-teniposide-carboplatin protocol and consolidated chemotherapy responses with focal therapy. We scored patients requiring irradiation, enucleation, or focal ablation of central vision as failures. In 21 study patients, the overall relapse-free rate at a median follow-up of 3.3 years was 76%, with a rate of 92% for newly diagnosed and 50% for previously treated, relapsed retinoblastoma. Our results for the most unfavorable tumors with vitreous seeds (86% at 3.5 years) are better than published success rates of irradiation for similar tumors, or irradiation with the same chemotherapy without cyclosporin (45% at 2. 6 years). These results also exceeded our historic success rate with similar chemotherapy without cyclosporin, focal therapy, and/or radiation in 19 equivalently poor-risk patients (relapse-free rate 37% at a median follow-up of 5.6 years, P = 0.032), 16 of whom were previously untreated (relapse-free rate also 37%, P = 0.012). A better outcome occurred with higher cyclosporin blood levels and projected tissue exposure. Cyclosporin did not enhance the usual chemotoxicity. This clinical study suggests that cyclosporin improves the long-term response of retinoblastoma to chemotherapy, possibly by more than one mechanism.
A Digital TRNG Based on Cross Feedback Ring Oscillators (2013)

In this paper, a new digital true random number generator based on Cross Feedback Ring Oscillators (CFRO) is proposed. The random sources of CFRO lie in delay variations (jitter), unpredictable transition behaviors as well as metastability. The CFRO is proved to be truly random by restarting from the same initial states. Compared with the so-called Fibonacci Ring Oscillator (FIRO) and Galois Ring Oscillator (GARO), the CFRO needs less than half of their time to accumulate relatively high entropy and enable extraction of one random bit. Only a simple XOR corrector is used to reduce the bias of output sequences. TRNG based on CFRO can be run continuously at a constant high speed of 150Mbps. For higher security, the TRNG can be set in stateless mode at a cost of slower speed of 10Mbps. The total logical resources used are relatively small and no special placement and routing is needed. The TRNG both in continuous mode and in stateless mode can pass the NIST tests and the DIEHARD tests.

Synthesis of Dihalophenylacetic Acids Using Aromatic Nucleophilic Substitution Strategy (1997)

A simple synthetic strategy to dihalophenylacetic acids and specifically 3,5-difluorophenylacetic acid an important pharmaceutical intermediate was developed. The aromatic nucleophilic substitution of dihalofluorobenzenes using the anion of ethyl cyanoacetate yielded ethyl dihalophenylcyanoacetates. The basic decaroxylation of the ethyl dihalophenylcyanoacetates produced targeted dihalophenylacetic acids.
Log periodic dipole arrays (1960)

A new class of coplanar dipole arrays is introduced. The antennas described provide unidirectional radiation patterns of constant beamwidth and nearly constant input impedances over any desired bandwidth. The broad-band properties are achieved by making use of the principles of log periodic antenna design. Models are discussed which are capable of providing 8- to 9-db directive gain with an associated input standing wave ratio of 1:2:1 on a 75-ohm feeder, and this performance is independent of frequency. The free-space properties of several of these arrays have been measured and the results are presented. The antenna configuration is simple, permitting practical methods of fabrication, and the design should prove useful in many applications. It makes possible, for example, the construction of "all-wave" rotatable beams of very low cross section for use in the hf to uhf spectrum.
Whole-chip ESD protection strategy for CMOS IC's with multiple mixed-voltage power pins (2003)

A novel whole-chip ESD (electrostatic discharge) protection design with multiple ESD buses has been proposed to solve the ESD protection issue in CMOS ICs with multiple mixed-voltage power pins. The ESD current in the CMOS IC is diverted into the ESD buses, therefore the ESD current is conducted by the ESD buses away from the internal circuits and quickly discharged through the desired ESD protection devices. By using the ESD buses, the CMOS IC with separated power pins can be safely protected against ESD damage which is often located in the internal circuits.
Analysis of three different repeated DNA elements present in the P1 operon of<i>Mycoplasma pneumoniae</i>: size, number and distribution on the genome (1990)

Mycoplasma pneumoniae, a bacterium pathogenic for humans, has a relatively small genome size of 840 kbp. Even though, several repeated DNA elements have been identified in the genome of this prokaryote, particularly within the P1 gene which codes for a major adhesin protein of M. pneumoniae. These elements were characterized in detail with respect to size, number and distribution on the genome, represented by an ordered cloned library covering the complete chromosome. Three different repetitive elements were detected in and around the P1 gene designated as RepMP2/3, RepMP4 and RepMP5. The length of these elements varies between 1.1-1.5 kbp (RepMP4), 1.8 kbp (RepMP2/3) and 1.9-2.2 kpb (RepMP5). They occur at least 8 to 10 times on the chromosome. Possible functions are discussed and a uniform nomenclature for these repeats is proposed.
Implementing the Payment Card Industry (PCI) Data Security Standard (DSS) (2011)

Underpinned by the rise in online criminality, the payment card industry (PCI) data security standards (DSS) were introduced which outlines a subset of the core principals and requirements that must be followed, including precautions relating to the software that processes credit card data. The necessity to implement these requirements in existing software applications can present software owners and developers with a range of issues. We present here a generic solution to the sensitive issue of PCI compliance where aspect orientated programming (AOP) can be applied to meet the requirement of masking the primary account number (PAN). Our architecture allows a definite amount of code to be added which intercepts all the methods specified in the aspect, regardless of future additions to the system thus reducing the amount of work required to the maintain aspect. We believe that the concepts here will provide an insight into how to approach the PCI requirements to undertake the task. The software artefact should also serve as a guide to developers attempting to implement new applications, where security and design are fundamental elements that should be considered through each phase of the software development lifecycle and not as an afterthought.
Computationally predicted IgE epitopes of walnut allergens contribute to cross-reactivity with peanuts (2011)

Sequences with low PD value (< 8.5) to known IgE epitopes could contribute to cross-reactivity between allergens. This further validates the PD scoring method for predicting cross-reactive epitopes in allergens.
Synthesis of Novel Pentafluorosulfanylfurans. Two Retro-Diels−Alder Approaches (2006)

The first examples of furan substituted with an SF5 group are reported. 3-pentafluorosulfanylfurans were prepared from their respective 2-pentafluorosulfanyl-5-cyano-7-oxabicyclo[2.2.1]hept-2-ene precursors via retro-Diels-Alder reactions. Also, a tandem cycloaddition/retrocycloaddition reaction between 4-phenyloxazole and 1-pentafluorosulfanylhex-1-yne was used to prepare 3-pentafluorosulfanyl-4-butylfuran. [reaction: see text].
Digital Imaging of Occlusal Contacts in the Intercuspal Position (1994)

For the small sample evaluated, a large variation in occlusal contact size was found in the five records. The occlusal contact location was consistent in the five records. The measurement method developed seems to provide reliable measures of occlusal contact surface area and location.
Development of chitosan-coated gold nanoflowers as SERS-active probes (2010)

Surface-enhanced Raman scattering (SERS) has been intensely researched for many years as a potential technique for highly sensitive detection. This work, through the reduction of HAuCl(4) with pyrrole in aqueous solutions, investigated a facile one-pot synthesis of flower-like Au nanoparticles with rough surfaces. The formation process of the Au nanoflowers (AuNFs) was carefully studied, and a spontaneous assembly mechanism was proposed based on the time-course experimental results. The key synthesis strategy was to use pyrrole as a weak particle stabilizing and reducing agent to confine crystal growth in the limited ligand protection region. The nanometer-scale surface roughness of AuNFs provided several hot spots on a single particle, which significantly increased SERS enhancement. Good biocompatible stable Raman-active probes were synthesized by coating AuNFs with chitosan. The conservation of the SERS effects in living cells suggested that the chitosan-capped AuNFs could be suitable for highly sensitive detection and have potential for targeting of tumors in vivo.
Clustered-architecture motion control system utilizing IEEE 1394b communication network (2005)

This paper presents a scalable control system for synchronized control of complex multi-axis non-linear machines utilizing a communication network based on the IEEE I394b high-speed serial bus standard. The system introduces a unique clustered architecture which allows for a high level of centralization of control algorithms in clusters of remote controllers in selected areas while promoting distribution of control algorithms running on substantially autonomous controllers in other areas. As a result, high performance control can be achieved where necessary without burdening the entire communication network by a heavy time-critical traffic and impairing the overall scalability of the control system. The distributed nature of the control system opens numerous challenges in the areas of implementation of model-based control, synchronization of individual controllers, and handling of events associated with inputs on multiple controllers. The paper proposes practical solutions to these challenges in the framework of the IEEE 1394b standard.
Identification of an <i>Escherichia coli</i> O157:H7 heme oxygenase with tandem functional repeats (2005)

Heme oxygenases (HOs) catalyze the oxidation of heme to biliverdin, carbon monoxide (CO), and free iron. Iron acquisition is critical for invading microorganisms to enable survival and growth. Here we report the crystal structure of ChuS, which displays a previously uncharacterized fold and is unique compared with other characterized HOs. Despite only 19% sequence identity between the N- and C-terminal halves, these segments of ChuS represent a structural duplication, with a root-mean-square deviation of 2.1 A between the two repeats. ChuS is capable of using ascorbic acid or cytochrome P450 reductase-NADPH as electron sources for heme oxygenation. CO detection confirmed that ChuS is a HO, and we have identified it in pathogenic Escherichia coli O157:H7. Based on sequence analysis, this HO is present in many bacteria, although not in the E. coli K-12 strain. The N- and C-terminal halves of ChuS are each a functional HO.

Measuring credibility of users in an E-learning social network (2010)

Learning Villages (LV) is an E-learning platform for people's online discussions and frequently citing postings of one another. It will greatly improve learning efficiency if credible users can be accurately identified in the E-learnning community. In this paper, we propose a novel method to rank credibility of users in the LV system. We first propose a k-EACM graph to describe the article citation structure in the LV system. The k-EACM graph not only describes the citation attitude between articles but also takes into account indirect citation links. We further build a weighted graph model k-UCM graph to reveal the implicit relationships between users hidden behind the citations among their articles. Finally, we design a graph based ranking algorithm, called Credible Author Ranking (CAR) algorithm, which can be applied to rank nodes in a graph with negative edges. We perform experiments on three simulated data sets. The experimental results show that our proposed method works well to rank credibility of users in the LV system. The comparison of results on average credibility of users in each set and composition of users in top N of three cases demonstrates that the CAR algorithm ranks users credibility in consistent with the predefined ground truth.
Cardiac repair in guinea pigs with human engineered heart tissue from induced pluripotent stem cells (2016)

Myocardial injury results in a loss of contractile tissue mass that, in the absence of efficient regeneration, is essentially irreversible. Transplantation of human pluripotent stem cell-derived cardiomyocytes has beneficial but variable effects. We created human engineered heart tissue (hEHT) strips from human induced pluripotent stem cell (hiPSC)-derived cardiomyocytes and hiPSC-derived endothelial cells. The hEHTs were transplanted onto large defects (22% of the left ventricular wall, 35% decline in left ventricular function) of guinea pig hearts 7 days after cryoinjury, and the results were compared with those obtained with human endothelial cell patches (hEETs) or cell-free patches. Twenty-eight days after transplantation, the hearts repaired with hEHT strips exhibited, within the scar, human heart muscle grafts, which had remuscularized 12% of the infarct area. These grafts showed cardiomyocyte proliferation, vascularization, and evidence for electrical coupling to the intact heart tissue in a subset of engrafted hearts. hEHT strips improved left ventricular function by 31% compared to that before implantation, whereas the hEET or cell-free patches had no effect. Together, our study demonstrates that three-dimensional human heart muscle constructs can repair the injured heart.
Manufacturing characteristics associated with strut fracture in Björk-Shiley 60 degrees Convexo-Concave heart valves. (1995)

Björk-Shiley Convexo-Concave (CC) valves sometimes experience fracture of the outlet strut. Previously implicated valve characteristics that predict strut fracture include larger valve size, larger opening angle (70 degrees vs 60 degrees), remilling, weld date, and implant in the mitral position. While the associations between risk, size, and opening angle suggest that part of the elevated incidence of strut fracture might be due to the design of the Björk-Shiley valves, only a small fraction of implanted valves have experienced strut fracture. In consequence, previously unexamined variations in the manufacturing process have been suggested as possible factors affecting the failure risk of individual valves; materials, manufacturing steps, quality control, and specific workers have all been put forward as potential explanations for valve-to-valve variation in risk. We conducted a case-control study of CC60 degrees valves implanted in the USA and Canada and manufactured between January 1, 1979 and March 31, 1984. Cases included all verified strut fractures reported to the manufacturer from 1979 through January, 1992. up to 10 controls were selected for each case. Controls were matched to cases on implanting surgeon and were required to have been implanted and functioning at least as long as their respective case valves. We reviewed case and control manufacturing records. There were 150 cases and 1095 surgeon-matched controls. Large mitral valves were at greatest risk of strut fracture; 33mm mitral valves were estimated to be 23 times more likely to fracture than 21-25mm aortic valves. Valves welded in 1979 and 1980 were less likely to fracture than those welded in any other time period; however, no specific manufacturing procedures or personnel were uniquely associated with this time period. Valves with more flexible outlet struts, as determined by the hook deflection and load deflection tests during manufacture, appear to have been at higher risk than valves with more rigid outlet struts. There were three welders who had worked on a sufficient number of valves to allow separate estimation of the risk in the valves they welded. One welder's work was associated with about one-third the risk of valves worked on by the other two. Examination of receiver operating characteristic curves revealed, however, that welder identity added little to the discriminating information already available in the form of valve size and implant position. It is concluded that welder identity and strut flexibility appear to contribute to the risk of outlet strut fracture in Björk-Shiley CC60 degrees valves. Neither of these factors, however, is sufficient to account for much of the previously unexplained variation in risk. No other characteristic measurable in existing manufacturing records appears to predict risk of strut fracture in any useful way.
Dynamic feature generation and selection on heterogeneous graph for music recommendation (2016)

In the past decade, online music streaming services (MSS), e.g., Pandora and Spotify, revolutionized the way people access, consume and share music. MSS serve users with a huge digital music library, various kinds of music discovery channels, and a number of tools for music sharing and management (e.g. bookmark, playlist, comment, etc.). As a result, metadata and user-generated data hosted on MSS demonstrate great heterogeneity, which provides important potential to enhance music recommendation performance. In this study, we propose a novel music recommendation approach by leveraging heterogeneous graph schema mining and ranking feature selection. Unlike existing heterogeneous graph-based recommendation techniques, the new method can automatically generate and select the optimized meta-path-based features for the learning to rank model. To make feature selection more efficient, we propose the Dynamic Feature Generation Tree algorithm (DFGT), which can activate and eliminate the short sub-meta-paths for feature evolution at a low cost. Experiments show that the proposed algorithm can efficiently generate optimized ranking feature set for meta-path-based music recommendation, which significantly enhances the state-of-the-art collaborative filtering algorithms.
