DiG-Park: A Smart Parking Availability Searching Method Using V2V/V2I and DGP-Class Problem (2017)

Localization systems for outdoor areas using GNSS based systems (like GPS, GLONASS and more) are nowadays widespread and commonly-available in devices like smartphones. For indoor localization, on the other hand, several methods has been proposed in the latest years, like inertial navigation systems (INS) or wireless positioning systems (WPS, like wireless trilateration or fingerprinting methods), but an always-available and reliable technology is still under research. Vehicle-2-vehicle and Vehicle-2-infrastructure technologies allow vehicles to communicate via wireless to issue security warnings and to share traffic information. In this paper we propose an alternative localization technique based on the presence of nearby vehicles and known fixed infrastructures like generic radio hotspots. We aim to improve localization accuracy of the user in indoor parking lots using a combination of wireless radio signal strenght-to-distance evaluation, V2V/V2I, and a DGP algorithm, allowing users to rapidly find a free parking spot. This grade of accuracy is mandatory in indoor car park scenario since the vehicles are very close one to another in comparison with normal road traffic.
Electrical parameter changes in silicon solar cells induced by thermal donor formation (2002)

Statistical results of 450 degrees C annealing experiments of variable duration, performed on n/sup +/pp+, 10 Omega -cm Czochralski silicon (Cz silicon), bifacial solar cells are presented. The specific temperature used is known to favor the nucleation of interstitial oxygen, creating the thermal donors, with important effects on the electrical properties of Cz silicon. Two distinct behaviors are observed with solar cells. The annealing during moderate time (below 4-5 h) leads, on average, to an improvement of the photovoltaic performances. Longer heat treatments (mainly above 8 h) induce an effective inversion of the base polarity (from p type to n type), with the net result of partially losing the precedent benefits. Both phenomena have been found to be permanent, provided further processes at higher temperatures are avoided.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>

The 123s of ABC in SAP: Using SAP R/3 to Support Activity-Based Costing (2001)

From the Publisher:
Activity-Based Costing (ABC), a method that measures the cost and performance of activities, resources, and cost objects, is becoming increasingly adopted in today's market as more and more companies realize that the current generation of systems can efficiently support it. As companies continue to make a huge investment of both money and effort in their SAP system, they seek ways to incorporate the benefits of Activity-Based Costing into their current SAP system.
The 123s of ABC in SAP shows corporations exactly how the ABC approach can be effectively incorporated into today's SAP systems. While SAP training teaches what buttons in the system to push and ABC courses and workshops teach the philosophy, consultants Dawn Sedgley and Christopher Jackiw provide the first documentation on how to apply the ABC philosophy to the SAP costing engine -- in short, how to use the tool to support the ideas.
The book is designed for readers with advanced knowledge of the ABC framework but does not assume the reader has any familiarity with the SAP R/3 application. In clear, nontechnical language, the authors provide a basic explanation of SAP R/3, specifically, the Controlling Module (CO) including the CO-ABC component. The SAP-CO module, which is the costing engine of the system, is based on the German costing philosophy, which is being augmented and repackaged under the name Resource Consumption Accounting for the U.S. market. You will learn the difference between the American and German philosophies, the benefits of using them together, and what management decision information they can provide.
To assist you in grasping the concepts, the book takes a pictorial approach. Illustrations are also completely linked and built upon, effectively generating a large-scale case study whose lessons you can apply to your needs.
As large companies shift to enhancement-type projects once their SAP implementations have been completed, effective implementation of SAP ABC will become ever more critical to the success of your company. A must for CFOs, controllers, cost managers, SAP project managers, SAP-C level leaders, and SAP-CO team members, The 123s of ABC in SAP will provide valuable answers to the critical question, How can I maximize my investment in my SAP R/3 system?

Rapid Flow Cytometry Test for Identification of Different Carbapenemases in Enterobacteriaceae (2016)

A flow cytometry test was developed to identify carbapenemase production by Enterobacteriaceae and to discriminate between the different types of carbapenemases (classes A, B, and D). It is based on the detection of meropenem activity against bacteria, coupled with different carbapenemase inhibitors, which is assessed by flow cytometry. It represents a convenient, fast, and reliable approach (100% sensitivity and 100% specificity) for the detection and characterization of different carbapenemases.
Purification of pyruvate formate-lyase from Streptococcus mutans and its regulatory properties (1982)

Pyruvate formate-lyase (EC 2.3.1.54) from Streptococcus mutans strain JC2 was purified in an anaerobic glove box, giving a single band on disk and sodium dodecyl sulfate electrophoresis. This enzyme was immediately inactivated by exposure to the air. Enzyme activity was unstable even when stored anaerobically, but the activity was restored by preincubating the inactivated crude enzyme with S-adenosyl-L-methionine, oxamate, and reduced for ferredoxin or methylviologen. On the other hand, the purified enzyme was not reactivated. Either D-glyceraldehyde 3-phosphate or dihydroxyacetone phosphate strongly inhibited this enzyme. The inhibitory effects of these compounds were largely influenced by enzyme concentration. The inhibition of these triose phosphates in cooperation with the reactivating effect of ferredoxin and the fluctuations of both the enzyme and the triose phosphate levels may efficiently regulate the pyruvate formate-lyase activity in S. mutans in vivo.
A Label-free CMOS DNA Microarray based on Charge Sensing (2008)

The first label-free CMOS DNA polymerization sensor is reported. The 5-by-5 sensor array measures the charge induced on an electrode from a DNA fragment undergoing polymerization. Importantly, no post-processing is required as passivated top-metal electrodes are used. The measured limit of detection (with enzymatic buffer) is 25 fA for a one second integration time, or equivalently 25 fC of charge, although the limit set by the electronic noise is 3.5 times smaller. Using our chip, we demonstrate the detection of DNA polymerization. The sensor can be used to sequence short DNA segments in addition to detect DNA hybridization in microarrays.
Motion-compensated noncontact imaging photoplethysmography to monitor cardiorespiratory status during exercise (2011)

With the advance of computer and photonics technology, imaging photoplethysmography [(PPG), iPPG] can provide comfortable and comprehensive assessment over a wide range of anatomical locations. However, motion artifact is a major drawback in current iPPG systems, particularly in the context of clinical assessment. To overcome this issue, a new artifact-reduction method consisting of planar motion compensation and blind source separation is introduced in this study. The performance of the iPPG system was evaluated through the measurement of cardiac pulse in the hand from 12 subjects before and after 5 min of cycling exercise. Also, a 12-min continuous recording protocol consisting of repeated exercises was taken from a single volunteer. The physiological parameters (i.e., heart rate, respiration rate), derived from the images captured by the iPPG system, exhibit functional characteristics comparable to conventional contact PPG sensors. Continuous recordings from the iPPG system reveal that heart and respiration rates can be successfully tracked with the artifact reduction method even in high-intensity physical exercise situations. The outcome from this study thereby leads to a new avenue for noncontact sensing of vital signs and remote physiological assessment, with clear applications in triage and sports training.
Investigating flexible textile-based coils for wireless charging wearable electronics (2019)

Smart and interactive textiles have been attracted great attention in recent years. This research explored three different techniques and processes in developing textile-based conductive coils that are able to embed in a garment layer. Coils made through embroidery and screen printing have good dimensional stability, although the resistance of screen printed coil is too high due to the low conductivity of the print ink. Laser cut coil provided the best electrical conductivity; however, the disadvantage of this method is that it is very difficult to keep the completed coil to the predetermined shape and dimension. The tested results show that an electromagnetic field has been generated between the textile-based conductive coil and an external coil that is directly powered by electricity. The magnetic field and electric field worked simultaneously to complete the wireless charging process.
One-year Follow-up of Custom Phototherapeutic Keratectomy (2004)

At 1 year after surgery, custom phototherapeutic keratectomy (CPK) provided a reliable tool for treatment of highly aberrated eyes, and provided a surgical alternative to penetrating keratoplasty.
Preparation and Properties of AlON-SiAlON Composites. (2001)

AlON-SiAl7O2N7 composites were prepared in order to improve the oxidation characteristics of AlON ceramics. Composites with different ratios of AlON/SiAl7O2N7 were obtained by heating mixtures with different Al2O3/AlN/Si3N4 ratios at 1750°C in 0.5MPa N2 for 2h. Since sintering of SiAl7O2N7 progresses by an evaporation-condensation mechanism accompanied by evolution of SiO gas, densification of AlON-SiAl7O2N7 composites is hard to achieve. The oxidation behavior of the obtained composies was investigated in air at 1300°C. Compared with a monolithic-AlON material, the AlON-SiAl7O2N7 composites showed higher oxidation resistance because the formed surface layer with glass phase inhibited inward diffusion of oxygen.
The Effect of MS-430, a Synthetized Pyrimidine Compound, on Regeneration of Nerve Fibers of Rats after Crush Injury (1995)

One of the synthetized pyrimidine compounds, 2-piperidino-7-methyl-6-oxo-5,6-dihydro-(7H) pyrrolo [2,3-d] pyrimidine maleate (MS-430), has neurotropic effects in vitro. Therefore, we studied the effect of MS-430 on regeneration of the myelinated fibers of the peroneal and sural nerve of Sprague-Dawley rats after crush injury in two tests, intraperitoneally administered daily 1.0 mg/kg (test 1, n = 7) and 7.5 mg/kg (test 2, n = 8) of MS-430, respectively. We then compared the effects with the control rats (n = 7) administered similarly as in the tests with physiological saline for 14 days from the day after crushing. Twenty-four hours after completion of the administration, the sural nerves at 7.5 mm and 15 mm distal to the crushed site, and the peroneal nerve at 15 mm distal to the crushed site were removed from each rat used in the two tests and from the controls, and then embedded into epoxy resin. In the sural nerve, the total number of regenerated myelinated fibers per nerve in test 2 was greater (P < 0.05) than in the controls at 7.5 mm distal to the crushed site. However, it was similar among the three groups at 15 mm distal to the crushed site. In the case of the peroneal nerve, it was greater in both tests 1 and 2 than in the controls, however the difference was not statistically significant.(ABSTRACT TRUNCATED AT 250 WORDS)
A Therapeutic Anti–VEGF Antibody with Increased Potency Independent of Pharmacokinetic Half-life (2010)

Bevacizumab [Avastin; anti-vascular endothelial growth factor (VEGF) antibody] is an antiangiogenic IgG approved for treating patients with certain types of colon, breast, and lung cancer. In these indications, bevacizumab is administered every 2 to 3 weeks, prompting us to study ways to reduce the frequency of administration. Increasing affinity to neonatal Fc receptor (FcRn) may extend the pharmacokinetic half-life of an antibody, but the quantitative effect of FcRn affinity on clearance has not been clearly elucidated. To gain further insight into this relationship, we engineered a series of anti-VEGF antibody variants with minimal amino acid substitutions and showed a range of half-life improvements in primates. These results suggest that, if proven clinically safe and effective, a modified version of bevacizumab could potentially provide clinical benefit to patients on long-term anti-VEGF therapy through less-frequent dosing and improved compliance with drug therapy. Moreover, despite having half-life similar to that of wild-type in mice due to the species-specific FcRn binding effects, the variant T307Q/N434A exhibited superior in vivo potency in slowing the growth of certain human tumor lines in mouse xenograft models. These results further suggest that FcRn variants may achieve increased potency through unidentified mechanisms in addition to increased systemic exposure.
Endocrine Alterations in the Aging Male (2003)

The recent increase in the elderly population, current health trends and awareness of age-related changes in the male endocrine system, have led to discussions about the role of the hormonal changes in the aging process in males. Better prevention and treatment of suboptimal health status and age-related diseases in aging men are based on an improved understanding of aging, particularly of the significance of age-associated hormonal changes. The aims of this study were 1) to evaluate the age dependence of the serum concentrations of the following important hormonal parameters in adult males using the IMMULITE 1 automated assay system (DPC, Los Angeles): testosterone, dehydro-epiandrosterone sulfate (DHEAS), estradiol (E2), sex hormone binding globulin (SHBG), lutropin (LH), follitropin (FSH), cortisol, prolactin, thyroid stimulating hormone (TSH), free triiodothyronine (fT3), free thyroxine (fT4) and the growth hormone-dependent parameters insulin-like growth factor (IGF-I) and IGF-binding protein-3 (IGFBP-3) and 2) to derive the following parameters: calculated free testosterone (cFT), ratio of calculated free testosterone to total testosterone (% cFT) and free androgen index (FAI). We found a significant decrease between the 21-30-year age group and the > 70-year age group for total testosterone (-42.4%), FAI (-65.5%), cFT (-60.0%), % cFT (-30.0%), DHEAS (-71.9%), E2 (-35.4%), TSH (-23.6%), IGF-I (-40.3%) and IGFBP-3 (-26.5%). Since the decreases in the FAI and cFT were greater than that of total testosterone and because these derived parameters reflect the biologically active fraction of testosterone, FAI and cFT are better markers for androgen deficiency in males. In contrast, a significant increase with age was observed for SHBG (+61.2%), LH (+40.0%), FSH (+98.3%) and cortisol (+54.2%). No significant alterations with age were observed for prolactin, fT3 and fT4. The study demonstrates that determining complete profiles of the androgenic, gonadotropic, adrenocortical, thyroid, pituitary and growth hormone/IGF endocrine axes in middle-aged and elderly men may be helpful in obtaining a correct clinical diagnosis for various hormonal disorders.
High-resolution two-field nuclear magnetic resonance spectroscopy (2016)

Nuclear magnetic resonance (NMR) is a ubiquitous branch of spectroscopy that can explore matter at the scale of an atom. Significant improvements in sensitivity and resolution have been driven by a steady increase of static magnetic field strengths. However, some properties of nuclei may be more favourable at low magnetic fields. For example, transverse relaxation due to chemical shift anisotropy increases sharply at higher magnetic fields leading to line-broadening and inefficient coherence transfers. Here, we present a two-field NMR spectrometer that permits the application of rf-pulses and acquisition of NMR signals in two magnetic centres. Our prototype operates at 14.1 T and 0.33 T. The main features of this system are demonstrated by novel NMR experiments, in particular a proof-of-concept correlation between zero-quantum coherences at low magnetic field and single quantum coherences at high magnetic field, so that high resolution can be achieved in both dimensions, despite a ca. 10 ppm inhomogeneity of the low-field centre. Two-field NMR spectroscopy offers the possibility to circumvent the limits of high magnetic fields, while benefiting from their exceptional sensitivity and resolution. This approach opens new avenues for NMR above 1 GHz.
(-)-[125I]-iodopindolol, a new highly selective radioiodinated beta-adrenergic receptor antagonist: measurement of beta-receptors on intact rat astrocytoma cells. (1980)

(-)-Pindolol, one of the most potent beta-adrenergic receptor antagonists, was radioiodinated using chloramine-T oxidation of carrier-free Na 125I and separated from unreacted pindolol to yield 2200 Ci/mmole (-)-[125I]-iodopindolol ((-)-[125I]-IPin). Mass and ultraviolet spectra confirmed that the iodination occurred on the indole ring, presumably at the 3 position. The binding of radiolabeled (-)-[125I]-IPin to beta-adrenergic receptors has been studied using intact C6 rat astrocytoma cells (2B subclone) grown in monolayer cultures. Binding of (-)-[125I]-IPin was saturable with time and concentration. Using 13 pM (-)-[125I]-IPin, binding equilibrium was reached in 90 min at 21-22 degrees C. The reverse rate constant was 0.026 min-1 at 21 degrees C. Specific binding (expressed as 1 microM (-)-propranolol displaceable counts) of (-)-[125I]-IPin was 95% of total binding. Scatchard analysis of (-)-[125I]-IPin binding revealed approximately 4300 receptors/cell and a dissociation constant of 30 pM. This was in excellent agreement with the kinetically determined dissociation constant of 35 pM. Displacement by propranolol and isoproterenol showed that (-)-[125I]-IPin binding sites were pharmacologically and stereospecifically selective. These results indicate that (-)-[125I]-IPin, a pure (-)-stereoisomer, high specific activity radioligand, selectively binds to beta-adrenergic receptors in whole cells with a high percentage of specific binding and should therefore be useful in the study and measurement of cellular beta-adrenergic receptors.
DISTRIBUTION AND COMPOSITION OF PECTINS IN SUNFLOWER PLANTS (1975)

The distribution and composition of pectins in the head and stem parts of Peredovik sunflower (Helianthus annuus L.) from a large field planting and four cultivars from a row-plot experiment were investigated. The total pectin contents of the head, bracts, neck and stalk of the field-grown Peredovik were 19, 11, 7 and 5%, respectively, but stalks accounted for 45% of the total plant pectin. The four cultivars varied from 15 to 24% of pectin in the heads and 4 to 7% of pectin in the stalks, depending on the maturity stage at harvest, cultivar and weight of plant parts. Water-soluble pectins constituted about one-quarter of the total head pectins. The remainder of the head pectins and all of the stalk pectins were extracted with a dilute solution of ammonium oxalate and oxalic acid, indicating that these pectins were bound by divalent metallic ions. The galacturonic acid levels of the pectin fractions were very high and the color properties of the dry pectin and precipitated gels appeared satisfactory. Although the methoxyl contents of sunflower pectin tended to be lower than values reported for commercial sources of plant pectin, there was considerable variation among the pectin fractions, cultivars, stages of maturity, and plant parts. Because of the variability in pectin and methoxyl content, further studies on cultivars, stages of maturity, and functional properties are necessary to determine the full potential of sunflowers as a new commercial source of pectin.

Cisplatin ototoxicity in gynecologic cancer patients. A preliminary report (1985)

The ototoxicity associated with long-term cisplatin therapy in gynecologic cancer patients was investigated. Twenty-three of 31 patients developed hearing loss and 21 patients reported the onset of tinnitus. The hearing loss was bilateral, cochlear, and permanent. The tinnitus was transient and not predictive of change in hearing level. The likelihood of developing hearing loss appeared to be greatest in patients older than 40 years and in patients with preexisting hearing loss. The amount of change did not appear to be related to the degree of preexisting hearing loss.
