A NEW APPROACH FOR TOOL PATH CONTROL IN ROBOTIC DEBURRING OPERATIONS (2003)

Robotic deburring has been used by industries to automate the manual operation, which is a constant source of problems related to lack of productivity and high risk of accidents. However, the automation of the deburring operation is not a trivial task. The high interaction between the tool and the workpiece, associated with the inconsistency of the burr formation, represents a big challenge to the programming and controlling system applied to the robots. This paper proposes a complete framework for an efficient robotic deburring implementation. The framework aims to integrate all the steps of the robotic implementation: trajectory programming for efficient burr removal, contact evaluation and definition of the control parameters, and finally the online trajectory control. The proposed controller combines two signals into a new parameter, Fast Abrasive Power (FAP), which represents a modularization of the power level by the ratio between instantaneous acoustic emission (AE) and average AE calculated over the last n points. The new fast power parameter maintains the reliability of the original power signal and incorporates the dynamics of the AE signal.

Vitamin D, Aging, and the 2005 Dietary Guidelines for Americans (2006)

The 2005 Dietary Guidelines for Americans recommend that older adults, people with dark skin, and those exposed to insufficient ultraviolet radiation (i.e., sunlight) consume extra vitamin D from vitamin D-fortified foods and/or supplements. Individuals in these high-risk groups should consume 25 μg (1000 IU) of vitamin D daily to maintain adequate blood concentrations of 25-hydroxyvitamin D, the biomarker for vitamin D status. This review considers recommendations for vitamin D-rich foods and dietary supplements, as well as specific problems with self-prescribing sun exposure or artificial sources of ultraviolet radiation to meet the vitamin D recommendations for older people.
Thermal Stability of Stacking Faults in β-SiC Specimens (1998)

Stacking faults in SiC are one of the important factors in treat SiC, since they affect physical and chemical properties. Ultra-pure β-SiC specimens with stacking faults were annealed at various temperatures for various duration in an Ar atmosphere under a condition without grain growth. Stacking faults decreased in two steps by heat treatment characterized by fast decrease and by slow decrease, respectively. The apparent activation energy for the former was estimated to be 182kJ/mol and that for the latter was estimated to be 260kJ/mol. The value of the latter corresponded to the activation energy for migration of carbon atoms in β-SiC. It was also observed that lattice strain decreased with decreasing stacking faults.
A rhodium catalyst for single-step styrene production from benzene and ethylene (2015)

Rising global demand for fossil resources has prompted a renewed interest in catalyst technologies that increase the efficiency of conversion of hydrocarbons from petroleum and natural gas to higher-value materials. Styrene is currently produced from benzene and ethylene through the intermediacy of ethylbenzene, which must be dehydrogenated in a separate step. The direct oxidative conversion of benzene and ethylene to styrene could provide a more efficient route, but achieving high selectivity and yield for this reaction has been challenging. Here, we report that the Rh catalyst ((Fl)DAB)Rh(TFA)(η(2)-C2H4) [(Fl)DAB is N,N'-bis(pentafluorophenyl)-2,3-dimethyl-1,4-diaza-1,3-butadiene; TFA is trifluoroacetate] converts benzene, ethylene, and Cu(II) acetate to styrene, Cu(I) acetate, and acetic acid with 100% selectivity and yields ≥95%. Turnover numbers >800 have been demonstrated, with catalyst stability up to 96 hours.

Synthesis, Biological Activity, and ADME Properties of Novel <i>S</i>‐DABOs/<i>N</i>‐DABOs as HIV Reverse Transcriptase Inhibitors (2012)

Previous studies aimed at exploring the SAR of C2-functionalized S-DABOs demonstrated that the substituent at this position plays a key role in the inhibition of both wild-type RT and drug-resistant enzymes, particularly the K103N mutant form. The introduction of a cyclopropyl group led us to the discovery of a potent inhibitor with picomolar activity against wild-type RT and nanomolar activity against many key mutant forms such as K103N. Despite its excellent antiviral profile, this compound suffers from a suboptimal ADME profile typical of many S-DABO analogues, but it could, however, represent a promising candidate as an anti-HIV microbicide. In the present work, a new series of S-DABO/N-DABO derivatives were synthesized to obtain additional SAR information on the C2-position and in particular to improve ADME properties while maintaining a good activity profile against HIV-1 RT. In vitro ADME properties (PAMPA permeation, water solubility, and metabolic stability) were also experimentally evaluated for the most interesting compounds to obtain a reliable indication of their plasma levels after oral administration.
New air-stable solution-processed organic n-type semiconductors based on sulfur-rich core-expanded naphthalene diimides (2011)

Among the reported organic n-type semiconductors naphthalene diimide (NDI) derivatives have received more and more attention. In this paper, we report two sulfur-rich expanded NDI derivatives 1 and 2 containing 1,3-dithiole-2-thione-4,5-dithiolate and 1,3-dithiole-2-one-4,5-dithiolate units, respectively. Electrochemical, absorption, spectral and theoretical calculation studies show that LUMO energies of 1 and 2 are lower than that of a typical NDI without functional substitution. OFET devices based on thin-films of 1 and 2 which can be easily solution-processed are fabricated with conventional techniques. The performance of OFET devices of 1 and 2 can be significantly improved by fast annealing (about 30 s) their thin-films in air, with high on/off ratios (106–107) and relatively high electron mobilities of up to 0.05 and 0.04 cm2 V−1s−1, respectively.

A reliable wireless ATM system (2002)

This paper describes the design of reliable wireless Asynchronous Transfer Mode (ATM) System to be used by the U.S. military and the commercial marketplace. This system, called Survivable ATM, consists of three main components: (1) Transmission Error Control System (TECS), (2) Reliable ATM Adaptation Layer (AAL), (3) Network Management System. These three components deliver a set of previously unavailable capabilities to achieve and maintain reliable performance of commercial ATM technology in wireless environments. These components collectively provide reliable end-to-end operation of ATM communication systems in deployed wireless terrestrial and satellite networks. At the data link layer, the TECS dynamically selects data link packet length and the strength of Forward Error Correction (FEC) coding. The result of this adaptive error control mechanism allows for the maximum utilization of bandwidth for wireless terrestrial and satellite communication systems. Higher performance can be achieved by "pushing down" the error correction lower on the protocol stack. The Reliable AAL, referred to as AAL "X", provides for residual error recovery during cases of ATM congestion, where the TECS cannot detect this type of condition. Environments with limited bandwidth capabilities, such as the U.S. military, can truly benefit from the Survivable ATM System.
Neutralizing Antibodies to Interferon- : Relative Frequency in Patients Treated with Different Interferon Preparations (1991)

The frequencies of antibody development so far reported in patients treated with different interferons (IFNs) are not readily comparable because of differences in treatment regimens and assay methods. Thus the frequency of neutralizing antibody development was analyzed in a large sample of sera derived from a relatively homogeneous group of patients treated with different IFN-alpha preparations. The frequency of developing neutralizing antibody to IFN varied according to the IFN given. Particularly, the seroconversion frequency was significantly higher in patients treated with recombinant IFN-alpha 2a (20.2%) than in patients treated with either recombinant IFN-alpha 2b (6.9%) or IFN-alpha N1 (1.2%), a lymphoblastoid IFN-alpha. Furthermore, sera obtained from patients treated with either recombinant IFN neutralized both types of recombinant IFNs but failed to neutralize IFN-alpha N1.
A precise packing sequence for self-assembled convex structures (2007)

Molecular simulations of the self-assembly of cone-shaped particles with specific, attractive interactions are performed. Upon cooling from random initial conditions, we find that the cones self-assemble into clusters and that clusters comprised of particular numbers of cones (e.g., 4-17, 20, 27, 32, and 42) have a unique and precisely packed structure that is robust over a range of cone angles. These precise clusters form a sequence of structures at specific cluster sizes (a "precise packing sequence") that for small sizes is identical to that observed in evaporation-driven assembly of colloidal spheres. We further show that this sequence is reproduced and extended in simulations of two simple models of spheres self-assembling from random initial conditions subject to convexity constraints, including an initial spherical convexity constraint for moderate- and large-sized clusters. This sequence contains six of the most common virus capsid structures obtained in vivo, including large chiral clusters and a cluster that may correspond to several non-icosahedral, spherical virus capsids obtained in vivo. Our findings suggest that this precise packing sequence results from free energy minimization subject to convexity constraints and is applicable to a broad range of assembly processes.
An Ultrasonic Method for Determining Axial Stress in Bolts (1986)

Abstract An ultrasonic technique for determining the axial stress within a bolt was developed and experimentally verified. The technique uses time-of-flight measurements of both shear and longitudinal waves propagating along the axis of a bolt along with the material parameters to calculate the stress acting on the bolt. One significant advantage of the technique is that an independent measurement of neither the original nor present length is required. Experimental results suggest that the method may be usable for fasteners which have experienced a small amount of plastic deformation.
Nickel/AlMe2Cl-catalysed carbocyanation of alkynes using arylacetonitriles (2009)

Nickel/Lewis acid dual catalysis was found to effect the carbocyanation reaction of alkynes using arylacetonitriles, giving a range of triply substituted acrylonitriles; the reaction of optically active alpha-phenylpropionitrile suggested a reaction mechanism that involves oxidative addition of a C-CN bond with retention of its absolute configuration.
Tiotropium - ein langwirksames, inhalatives Anticholinergikum zur Therapie der chronisch-obstruktiven Lungenerkrankung (COPD) (2003)

Anticholinergics are agents of first choice for the symptomatic treatment of patients with COPD. Tiotropium (Ba 679 BR, Spiriva) is a long-acting inhaled anticholinergic designed for once-daily bronchodilator treatment of COPD. Tiotropium is a selective antagonist of pulmonary M1 and M3 muscarinic receptor subtypes, that produces a long-lasting (24 hours), dose-dependent bronchodilation and bronchoprotection against constrictive stimuli, e. g. methacholine, following inhalation of single doses. Clinical trials with tiotropium in COPD patients over a maximum treatment duration of one year have confirmed a persisting bronchodilator effect of tiotropium compared with placebo and ipratropium, as well as meaningful clinical improvements in lung function, hyperinflation, exercise tolerance, symptom control and quality of life. Moreover, recent trials indicate that treatment with tiotropium also reduces the frequency of COPD exacerbations and hospitalizations. Comparative trials further suggest that the bronchodilator potency of tiotropium may be superior to those of available COPD treatments. Besides a higher incidence of dry mouth, the side effect profile was comparable to ipratropium bromide. In conclusion, present clinical data suggest that tiotropium has the potential of a first-line treatment for patients with COPD.

Membrane Bioreactor (MBR) Technology for Wastewater Treatment and Reclamation: Membrane Fouling (2016)

The membrane bioreactor (MBR) has emerged as an efficient compact technology for municipal and industrial wastewater treatment. The major drawback impeding wider application of MBRs is membrane fouling, which significantly reduces membrane performance and lifespan, resulting in a significant increase in maintenance and operating costs. Finding sustainable membrane fouling mitigation strategies in MBRs has been one of the main concerns over the last two decades. This paper provides an overview of membrane fouling and studies conducted to identify mitigating strategies for fouling in MBRs. Classes of foulants, including biofoulants, organic foulants and inorganic foulants, as well as factors influencing membrane fouling are outlined. Recent research attempts on fouling control, including addition of coagulants and adsorbents, combination of aerobic granulation with MBRs, introduction of granular materials with air scouring in the MBR tank, and quorum quenching are presented. The addition of coagulants and adsorbents shows a significant membrane fouling reduction, but further research is needed to establish optimum dosages of the various coagulants/adsorbents. Similarly, the integration of aerobic granulation with MBRs, which targets biofoulants and organic foulants, shows outstanding filtration performance and a significant reduction in fouling rate, as well as excellent nutrients removal. However, further research is needed on the enhancement of long-term granule integrity. Quorum quenching also offers a strong potential for fouling control, but pilot-scale testing is required to explore the feasibility of full-scale application.
Mitochondrial optic neuropathies – Disease mechanisms and therapeutic strategies (2010)

Leber hereditary optic neuropathy (LHON) and autosomal-dominant optic atrophy (DOA) are the two most common inherited optic neuropathies in the general population. Both disorders share striking pathological similarities, marked by the selective loss of retinal ganglion cells (RGCs) and the early involvement of the papillomacular bundle. Three mitochondrial DNA (mtDNA) point mutations; m.3460G>A, m.11778G>A, and m.14484T>C account for over 90% of LHON cases, and in DOA, the majority of affected families harbour mutations in the OPA1 gene, which codes for a mitochondrial inner membrane protein. Optic nerve degeneration in LHON and DOA is therefore due to disturbed mitochondrial function and a predominantly complex I respiratory chain defect has been identified using both in vitro and in vivo biochemical assays. However, the trigger for RGC loss is much more complex than a simple bioenergetic crisis and other important disease mechanisms have emerged relating to mitochondrial network dynamics, mtDNA maintenance, axonal transport, and the involvement of the cytoskeleton in maintaining a differential mitochondrial gradient at sites such as the lamina cribosa. The downstream consequences of these mitochondrial disturbances are likely to be influenced by the local cellular milieu. The vulnerability of RGCs in LHON and DOA could derive not only from tissue-specific, genetically-determined biological factors, but also from an increased susceptibility to exogenous influences such as light exposure, smoking, and pharmacological agents with putative mitochondrial toxic effects. Our concept of inherited mitochondrial optic neuropathies has evolved over the past decade, with the observation that patients with LHON and DOA can manifest a much broader phenotypic spectrum than pure optic nerve involvement. Interestingly, these phenotypes are sometimes clinically indistinguishable from other neurodegenerative disorders such as Charcot-Marie-Tooth disease, hereditary spastic paraplegia, and multiple sclerosis, where mitochondrial dysfunction is also thought to be an important pathophysiological player. A number of vertebrate and invertebrate disease models has recently been established to circumvent the lack of human tissues, and these have already provided considerable insight by allowing direct RGC experimentation. The ultimate goal is to translate these research advances into clinical practice and new treatment strategies are currently being investigated to improve the visual prognosis for patients with mitochondrial optic neuropathies.
Two site‐specific endonucleases <i>Bin</i>SI and <i>Bin</i>SII from <i>Bifidobacterium infantis</i> (1983)

Two site-specific endonucleases, BinSI and BinSII, were isolated from Bifidobacterium infantis S76e. BinSI was found to be an isoschizomer of EcoRII, while BinSII was shown to have the same sequence and cutting specificity as BbeI, 5'-GGCGC decreases C-3'. Both BinSII- and BbeI-generated DNA fragments could be ligated with HaeII-generated DNA fragments.
Demonstration of the Preform Anneal Process to Form a One-Piece Aluminum Door Inner Panel (2006)

<div class="htmlview paragraph">A demonstration of the preform anneal process was conducted to form a one-piece aluminum door inner. In preform annealing, the aluminum panel is partially formed, annealed at 350°C to eliminate the cold work (strain hardening) from the first step, and then formed to the final shape using the same die. This process has the ability to form more complex parts than conventional aluminum stamping. Preform annealing uses non-age hardenable aluminum alloys of the 5xxx series and is suitable for a wide range of interior body panels. A rear door inner panel for a mid-size sports utility vehicle (SUV) was used in this study. This door inner was successfully created in one piece out of AA5182-O sheet with only slight design modifications to the original steel product geometry. The design of the door inner panel was conducted based on finite element analysis and predictions were verified with physical parts using thickness measurements and mechanical testing. Future opportunities for process development will also be discussed.</div>
P‐104: A New Voltage Modulated AMOLED Pixel Design Compensating Threshold Voltage Variation of Poly‐Si TFTs (2002)

Abstracts of the presentations follow.
Use of Two-Dimensional Polyacrylamide Gel Electrophoresis to Identify and Classify <i>Rhizobium</i> Strains (1980)

Fifty-seven strains of various Rhizobium species were analyzed by two-dimensional gel electrophoresis. Since the protein pattern on such gels is a reflection of the genetic background of the tested strains, similarities in pattern allowed us to estimate the relatedness between these strains. All group II rhizobia (slow growing) were closely related and were very distinct from group I rhizobia (fast growing). Rhizobium meliloti strains formed a distinct group. The collection of R. leguminosarum and R. trifolii strains together formed another distinct group. Although there were some similarities within the R. phaseoli, sesbania rhizobia, and lotus rhizobia, the members within these seemed much more diverse than the members of the above groups. The technique also is useful to determine whether two unknown strains are identical.
