Synthesis and characterization of perylene nanoparticles (2006)

Abstract Nanoparticles were prepared in different experimental conditions by a re‐precipitation method by use of perylene and polyvinylalcohol as active material and stabilizer, respectively. The excitation and emission spectral properties of dispersions in aqueous solutions of the various samples were recorded together with the fluorescence quantum yields and lifetimes (where detectable). The experimental results are consistent with the formation of excimer‐like states, responsible of the emission properties, in the nanoparticles. Confocal fluorescence and atomic force (AFM) microscopies were able to give information on the fluorescence properties and size distribution (most probable size of 3–5 nm) of the nanoparticles.

Surface model generation from range images of industrial environments (2004)

We present an hybrid segmentation technique that combines both the speed of an edge based approach with the robustness of a surface based approach. It consists of three stages. In the first stage a scan line approximation process extracts the edges contained into the given range image. These edges are later on used to define the positions of seed points. Through the second stage a two steps region growing technique is applied. First a 2D growing process enlarges the original seed points generating bigger regions. Next, each region is fitted to a plane and a cylinder. The one that best fit the given points is selected to represent that region and used during the 3D growing stage. The 3D growing stage is carried out taking into account the approximation error from candidate points to be added to the fitted surface. In this way, each surface is grown until no points can be added according to a user defined threshold. Finally, in the third stage, a post-processing algorithm merges neighbour regions that belong to the same surface. Experimental results by using industrial environments are presented.
Pose estimation for planar structures (2002)

We address the registration problem for interactive AR applications. Such applications require a real-time registration process. Although the registration problem has received a lot of attention in the computer vision community, it's far from being solved. Ideally, an AR system should work in all environments without the need to prepare the scene ahead of time, and users should be able to walk anywhere they want. In the past, several AR systems have achieved accurate and fast tracking and registration, putting dots over objects and tracking the dots with a camera. We can also achieve registration by identifying features in the scene that we can carefully measure for real-world coordinates. However, such methods restrict the system's flexibility. Hence, we need to investigate registration methods that work in unprepared environments and reduce the need to know the objects' geometry in the scene. We propose an efficient solution to real-time camera tracking for scenes that contain planar structures. We can consider many types of scene with our method. We show that our system is reliable and we can use it for real-time applications. We also present results demonstrating real-time camera tracking on indoor and outdoor scenes.
Pin-Fuse Seismic Systems - Friction Joints that Limit Damage (2015)

&lt;p&gt;Inspired by nature, Pin-Fuse systems such as steel beam-column joints, link elements, and braced frame assemblages have been developed. Inelastic deformation associated with drift levels of 3% or more is replaced with frictional deformation that does not damage the base materials involved. Connections slip in major events but remain fixed under wind and minor seismic loads. These systems lock elastic strain energy into the structure that can be recovered to re-centre the structure following a seismic event. Significant analytical studies and testing programs over several years have been performed on three systems—the Pin-Fuse Joint®, the Pin-Fuse Frame™ and the Link-Fuse Joint™—with US patents awarded. Since the behaviour of the friction material within the joints is crucial in providing appropriate system performance, major research and testing is currently underway on materials that are both predictable and durable.&lt;/p&gt;
Phase 3 randomized trial of chemotherapy with or without oblimersen in older AML patients: CALGB 10201 (Alliance) (2021)

Overexpression of B-cell leukemia/lymphoma 2 (BCL2) renders acute myeloid leukemia (AML) cells resistant to chemotherapy and has been associated with unfavorable outcomes. Oblimersen (G3139) is a phosphorothioate 18-mer antisense oligonucleotide directed against the first 6 BCL2 codons. In a phase 1 study of AML patients treated with G3139, cytarabine, and daunorubicin induction with cytarabine consolidation, no antisense-related toxicity was reported, and BCL2 downregulation occurred in patients achieving complete remission. In this phase 3 trial, untreated older AML patients were randomized to cytarabine (100 mg/m2 per day on days 4-10) and daunorubicin (60 mg/m2 per day on days 4-6) followed by cytarabine consolidation (2000 mg/m2 per day on days 4-8) with (arm A) or without (arm B) G3139 (7 mg/m2 per day on days 1-10 [induction] or days 1-8 [consolidation]). A total of 506 patients were enrolled. No differences in toxicity were observed between arms. Estimated overall survival (OS) at 1 year was 43% for arm A and 40% for arm B (1-sided log rank P = .13), with no differences in disease-free (DFS; P = .26) or event-free survival (P = .80). Subgroup analyses showed patients age <70 years in arm A had improved OS by 1 month vs those in arm B (P = .04), and patients with secondary AML in arm A had better DFS vs those in arm B (P = .04). We conclude that addition of G3139 to chemotherapy failed to improve outcomes of older AML patients. However, more effective means of inhibiting BCL2 are showing promising results in combination with chemotherapy in AML. This trial was registered at www.clinicaltrials.gov as #NCT00085124.
AN INVESTIGATION ON THE SEMINAL AND PERIODONTAL BACTERIA DIVERSITY AMONG SUBFERTILE MALES IN LAGOS (2019)

Background: This study was aimed at examining bacteria diversity in the semen and mouth ofinfertile men.Method: This was a case-control study of male (n=43) participants including infertile men (n=30)as test and fertile men (n=13) as control within 30-50 years of age. Semen, mouth swab and bloodsamples were collected and processed by standard practice. Semen and mouth swab samples werescreened to determine microbial presence. The semen qualitative and quantitative characteristicswere determined using standard methods. Blood serum samples were evaluated to determinehormonal and lipid profiles as well as liver and kidney function biomarkers using standard kits.Results: The frequency of bacterial occurrence or growth from the semen and mouth swab ofinfertile men was higher in comparison to the fertile group. Notably, the frequency ofStaphylococcus aureus (36.7%) isolated from infertile men semen was higher as compared to fertilemen with Staphylococcus aureus (15.4%). Moraxella catarrhalis (30%), Staphylococcus aureus(36.7%) and Escherichia coli (10.0%) were the major bacteria frequently isolated from infertilemen mouth swab in comparison to the fertile group with Moraxella catarrhalis (46.1%) andStaphylococcus aureus (23.3%). There was a significant decrease (p<0.05) in the semen volume,concentration and motility of the test group compared to the control group, with a correspondingsignificant increase (p<0.05) in the abnormal semen morphology of the test group compared to thecontrol. Significant (p<0.05) elevated levels of FSH and LH with decreased level of testosterone inthe infertile men as compared to the control was also observed.Conclusion: These results suggest increased bacteria diversity in relation to infertility. However, arelationship between bacterial isolates in the semen and mouth might exist.
Testing of Radiation Hardness in the Extreme-Ultraviolet Spectral Region (2007)

Currently we are commissioning a second multilayer‐based beamline to study the radiation hardness of multilayers under extreme‐ultraviolet (EUV) irradiation in an oxidizing atmosphere. Multilayer lifetime is one of the most important issues for the commercialization of extreme‐ultraviolet lithography. The beamline employs a spherical multilayer mirror and a beryllium filter. The mirror demagnifies the source and reflects 13.4 nm radiation as well as visible light. The beryllium filter suppresses the visible light reflected by the mirror and provides also a barrier between the extremely clean storage ring vacuum and the water atmosphere of the test chamber.
Stock Market Prediction on High-Frequency Data Using Generative Adversarial Nets (2018)

Stock price prediction is an important issue in the financial world, as it contributes to the development of effective strategies for stock exchange transactions. In this paper, we propose a generic framework employing Long Short-Term Memory (LSTM) and convolutional neural network (CNN) for adversarial training to forecast high-frequency stock market. This model takes the publicly available index provided by trading software as input to avoid complex financial theory research and difficult technical analysis, which provides the convenience for the ordinary trader of nonfinancial specialty. Our study simulates the trading mode of the actual trader and uses the method of rolling partition training set and testing set to analyze the effect of the model update cycle on the prediction performance. Extensive experiments show that our proposed approach can effectively improve stock price direction prediction accuracy and reduce forecast error.
Substance P effects on developing thymocytes in hindlimb unloaded rats. (2005)

Daily SP treatment was found to reverse the deleterious effects caused by HU and corticosterone in rat thymic immune cells. SP could prove to be an effective means for keeping the immune system functioning at normal levels in microgravity, allowing astronauts to stay in space longer and maintain a more productive immune system.
PERFECTORY: A Fault-Tolerant Directory Memory Architecture (2009)

The number of CPUs in chip multiprocessors is growing at the Moore's Law rate, due to continued technology advances. However, new technologies pose serious reliability challenges, such as more frequent occurrences of degraded or even nonoperational devices, and they threaten the cost-effectiveness and dependability of future computing systems. This work studies how to protect the on-chip coherence directory from fault occurrences. In a chip multiprocessor, cache coherence mechanisms such as directory memory are critical for offering consistent data view to all CPUs. We propose a novel online fault detection and correction scheme to enhance yield and resilience to runtime errors at a small performance cost. The proposed scheme uses smart encoding and coherence protocol adaptation strategies to salvage faulty directory entries. We also develop an online error recovery scheme that protects the directory memory from soft errors. We call our fault-tolerant directory memory architecture PERFECTORY. Evaluation results show that PERFECTORY achieves very high fault resilience: Over 99 percent chip yield at 0.05 percent hard error ratio and 1,934 years MTTF at 1,000 FIT using a 100-processor cluster configuration. PERFECTORY limits performance degradation to less than 1 percent at 0.05 percent hard error ratio and requires significantly smaller area overheads than existing redundancy approaches.
Limitations in the Use of Small-Length Flexural Pivot in a Pseudo-Rigid-Body Model (2015)

This paper investigates the effective use of the pseudo-rigid-body model (PRBM) of a small-length flexural pivot (SLFP), examining its very definition, and providing helpful guidelines in the context of a compound compliant beam composed of both compliant and rigid segments. Traditionally, for convenience in modeling, the pseudo-rigid-body model of the small-length flexural pivot assumes the characteristic pivot to be placed at the center of the SLFP. It is also suggested that the length of the adjacent rigid segment is ten or more times larger than the length of the compliant segment. In recent times, a growing interest has been expressed to test this assumption and learn more about its limitations. This paper investigates the performance of the PRBM of the SLFP, for initially straight and initially curved compound compliant beams by varying the compliant to rigid segment length ratio. The error, defined by comparing the PRBM deflections with those obtained from the closed-form elliptic integral method, may be assigned an acceptable value in determining the limit value of the segment length ratio. Plots of the maximum deflection that may be obtained within an error limit of 3%, for various segment length ratios of a fixed-free, compound compliant beam are provided.
Sorafenib has soluble epoxide hydrolase inhibitory activity, which contributes to its effect profile in vivo (2009)

The advent of multikinase inhibitors targeting the vascular endothelial growth factor (VEGF) receptor has revolutionized the treatment of highly angiogenic malignancies such as renal cell carcinoma. Interestingly, several such inhibitors are commercially available, and they each possess diverse specific beneficial and adverse effect profiles. In examining the structure of sorafenib, it was hypothesized that this compound would possess inhibitory effects on the soluble epoxide hydrolase, an enzyme with pleiotropic effects on inflammation and vascular disease. We now show that sorafenib but not another VEGF receptor targeted inhibitor sunitinib is a potent inhibitor of the human soluble epoxide hydrolase in vitro (K(I) = 17 +/- 4 nmol/L). Furthermore, sorafenib causes the expected in vivo shift in oxylipid profile resulting from soluble epoxide hydrolase inhibition, evidence of a reduction in the acute inflammatory response. Lipopolysaccharide-induced hypotension was reversed with sorafenib but not sunitinib treatment, suggesting that soluble epoxide hydrolase inhibition accounts for at least part of the anti-inflammatory effect of sorafenib. The pharmacokinetic studies presented here in light of the known potency of sorafenib as a soluble epoxide hydrolase inhibitor indicate that the soluble epoxide hydrolase will be largely inhibited at therapeutic doses of sorafenib. Thus, it is likely that soluble epoxide hydrolase inhibition contributes to the beneficial effects from the inhibition of the VEGF receptor and other kinases during treatment with sorafenib.

Conditions that Favor Mating Disruption of Epiphyas postvittana (Lepidoptera: Tortricidae) (1992)

Mating disruption of Epiphyas postvittana (Walker) using Shin-Etsu dispensers that contained (E)-11-tetradecenyl acetate and (E,E)-9,11-tetradecadienyl acetate was investigated using pheromone traps, tethered virgin female moths, and assessment of larval damage in apples at harvest in small orchard blocks (<0.5 ha). Pheromone trap catches were completely suppressed for 9 mo by a single application of synthetic pheromone. Catches did not return to control levels for 12 mo. Mating disruption, investigated for 94 wk, was completely achieved in 100% of weeks when average weekly release rates were ≥12 mg/ha per h, in 84% of weeks with 8–12 mg/ha per h, and in 68% of weeks with <5 mg/ha per h. The majority of failures to disrupt mating occurred in the following spring. Along with low pheromone release rate, coincident high activity of males outside the orchards (1–2.5 males per trap per day) appear likely to be major factors in 90% of failures to disrupt mating completely within the orchards. A change from pheromone blend close to the natural blend to one with significantly more isomeric impurity (a change from ≈3 to 30%, (Z)-11-tetradecenyl actetate) did not adversely affect efficacy, measured by prevention of trap catch or mating of tethered females. Trap catch 50 m outside treated blocks was correlated with frequency of mating by tethered females 5 m away, but the parameters were not related to fruit damage by larvae at harvest on the nearest orchard border.
Effect of Molecular Weight and Degree of Substitution of a Sodium-Carboxymethyl Cellulose Binder on Li4Ti5O12 Anodic Performance (2013)

This paper presents a detailed investigation of the influence of molecular weight (MW) and degree of substitution (DS) of sodium-carboxymethyl cellulose (CMC) used as binder of Li4Ti5O12 (LTO) anodes. CMC MW and DS were in the range of 90 000 to 700 000 and 0.7 to 1.2, respectively. As demonstrated by coin cell tests, the LTO electrode that contained relatively low MW and high DS CMC showed excellent cyclic performance above 150 mAh g–1 even after 100 cycles. Unlike typical electrodes, the adhesion strength of the LTO electrodes was not a critical factor for cell performance. On the contrary, low coverage of CMC on the surface of LTO, which leads to weak adhesion, was more favorable to the cell performance than strong adhesion caused by high coverage. Both an increase in the DS and a decrease in the MW of CMC gave rise to low charge transfer resistance, high ion conductivity, good wettability with the electrolyte, and good lithium ion mobility owing to a relatively large amount of LTO exposed to directly the electrolyte so long as critical adhesion is guaranteed in the LTO electrode.
Covalent modification of glassy carbon electrode with glutamic acid for simultaneous determination of uric acid and ascorbic acid (2001)

A novel covalently modified glassy carbon electrode with glutamic acid has been fabricated via an electrochemical oxidation procedure and was applied to the catalytic oxidation of uric acid (UA) and ascorbic acid (AA), reducing the overpotentials by about 0.2 V and 0.3 V, respectively. Based on its strong catalytic function toward the oxidation of UA and AA, the modified electrode resolved the overlapping voltammetric response of UA and AA into two well-defined voltammetric peaks with both cyclic voltammetry (CV) and differential pulse voltammetry (DPV), which can be used for the simultaneous determination of these species in a mixture. The catalytic peak current obtained from DPV was linearly dependent on the UA and AA concentration in the range 2 x 10(-6)-4 x 10(-4) mol L-1 and 1.0 x 10(-6)-4 x 10(-4) mol L-1 with correlation coefficients of 0.996 and 0.997, respectively. The detection limits (3 delta) for UA and AA were 1.1 x 10(-6) mol L-1 and 9.2 x 10(-7) mol L-1, respectively. The modified electrode shows good sensitivity, selectivity and stability, and has been applied to the determination of UA and AA simultaneously in human urine samples with satisfactory results.
MAC performance analysis and enhancement 100 Mbps data rates for IEEE 802.11 (2003)

The IEEE 802.11 specifications provide up to 54 Mbps data rate. Furthermore, the industry is seeking higher data rates (HDR's) over 100 Mbps for IEEE 802.11a extension. In this paper, we explore the overhead of HDR's to find out whether the MAC is good enough for the increasing data rates and what to expect as the industry seeks much higher data rates. We prove that a theoretical throughput upper limit and a theoretical delay lower limit exist for IEEE 802.11 protocols. The existence of such limits indicates that the overhead must be reduced to get good performance for HDR's. In order to reduce overhead, we introduce a burst transmission and acknowledgement (BTA) mechanism, in which, instead of acknowledging each packet, a burst of packets is received first, and then the whole burst is acknowledged one time.
Stereoselectivity in the double reductive alkylation of pyrroles: synthesis of cis-3,4-disubstituted pyrrolidines (1999)

Design and Control of a Permanent Magnet RotLin Motor for New Foldable Photovoltaic Units (2019)

In this study, a new permanent magnet rotary-linear (RotLin) motor is proposed for foldable photovoltaic units. Firstly, the mechanical structure, operation principles and magnetic circuits of the motor are introduced, and a design procedure elaborated the parameters calculation in the linear part and the rotary part. Finite element method (FEM) is used to analyze the magnetic field of the motor, and linear force outputs and torque outputs are obtained. Secondly, a control scheme is designed for the prototype of the motor including the position control and the speed control. The deformation on the mover and the magnetic coupling effect between the linear part and the rotational part are discussed. Finally, experimental results show that this motor can simultaneously realize a linear movement with continuous rotation. The linear poisoning accuracy can achieve 0.4 µm and the angular speed can be controlled with steady errors less than 3 rpm, proving the effectiveness of the proposed RotLin motor.
