Towards Diagnostic X-Ray Cone-Beam Imaging of the Entire Spine in the Weight-Bearing Position (2017)

X-ray cone-beam (CB) imaging may play a tremendous role in the future of diagnostic radiology. Recently, an innovative, versatile X-ray system (Multitom Rax, Siemens Healthcare, GmbH, Forchheim, Germany) was introduced for diagnostic radiology. This system enables taking X-ray radiographs with high patient positioning flexibility, as well as acquiring semicircular short CB scans in a variety of orientations. Here, we are interested in programming this system to enable a novel data acquisition geometry that would cover the entire spine in the weight-bearing position. Such an imaging capability has never been demonstrated so far. However, we may expect it to play an important clinical role as there is clinical evidence that spine diseases would be more accurately interpretable in the weight-bearing position. We are furthermore interested in using a geometry that provides complete data so that CB artifacts may be avoided. We report on a first implementation of such a geometry that consists of two circular arcs connected by a line segment. We assessed immediate and short-term motion reproducibility, as well as ability to image the entire spine within a Rando phantom. Strongly encouraging results were obtained. Reproducibility with sub-mm accuracy was observed and the entire spine was accurately reconstructed.

26.2: Super Durable Cover Lens Film (2014)

Abstract A new, hard coated cover lens film for the display industry is described. Interference fringing is drastically reduced through the use of a novel primer. The mechanism of failure in abrasion and scratch testing is explained along with the implications of this for designing a robust cover lens film.
A Randomized Exhaustive Propositionalization Approach for Molecule Classification (2010)

Drug discovery is the process of designing compounds that have desirable properties, such as activity and non-toxicity. Molecule classification techniques are used along this process to predict the properties of the compounds in order to expedite their testing. Ideally, the classification rules found should be accurate and reveal novel chemical properties, but current molecule representation techniques lead to less than adequate accuracy and knowledge discovery. This work extends the propositionalization approach recently proposed for multi-relational data mining in two ways: it generates expressive attributes exhaustively and it uses randomization to sample a limited set of complex (“deep”) attributes. Our experimental tests show that the procedure is able to generate meaningful and interpretable attributes from molecular structural data, and that these features are effective for classification purposes.
Flower Scent of Some Traditional Medicinal Plants (1993)

The volatile constituents of the inflorescences of the following medicinal plants relevant to the perfume and flavor industry were analysed: Chamomile (Matricaria recutita L.), Roman chamomile (Chamaemelum nobile (L.) All.), Lavender-Cotton (Santolina chamaecyparissus L.), Valerian (Valeriana officinalis L.), and Meadowsweet (Filipendula ulmaria L. Maxim). Comparative analyses of headspace concentrates of unpicked flowers and of corresponding hydrodistillates showed significant differences in most cases.
Circular economy in drinking water treatment: reuse of ground pellets as seeding material in the pellet softening process (2014)

Calcium carbonate pellets are produced as a by-product in the pellet softening process. In the Netherlands, these pellets are applied as a raw material in several industrial and agricultural processes. The sand grain inside the pellet hinders the application in some high-potential market segments such as paper and glass. Substitution of the sand grain with a calcite grain (100% calcium carbonate) is in principle possible, and could significantly improve the pellet quality. In this study, the grinding and sieving of pellets, and the subsequent reuse as seeding material in pellet softening were tested with two pilot reactors in parallel. In one reactor, garnet sand was used as seeding material, in the other ground calcite. Garnet sand and ground calcite performed equally well. An economic comparison and a life-cycle assessment were made as well. The results show that the reuse of ground calcite as seeding material in pellet softening is technologically possible, reduces the operational costs by €38,000 (1%) and reduces the environmental impact by 5%. Therefore, at the drinking water facility, Weesperkarspel of Waternet, the transition from garnet sand to ground calcite will be made at full scale, based on this pilot plant research.
Correlations of Combustion Data for S. I. Engine Calculations - Laminar Flame Speed, Quench Distance and Global Reaction Rates (1978)

&lt;div class="htmlview paragraph"&gt;A survey has been made of existing data on laminar flame speed and two-plate quenching distance for the propane -0&lt;sub&gt;2&lt;/sub&gt;-N&lt;sub&gt;2&lt;/sub&gt; system. Semi-empirical correlations have been derived to express these quantities as functions of equivalence ratio, pressure, flame temperature and residual gas fraction, over the range of parameters appropriate to engine operation. Application of the quench-distance correlation to calculations of engine hydrocarbon-emissions is discussed in the light of available experimental data on the one-wall quenching process.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Also for use in hydrocarbon-emission calculations, a global reaction rate expression for engine hydrocarbon-oxidation has been obtained by fitting an Arrhenius expression to the available rate data in the temperature range 850°K &amp;lt;T &amp;lt;1250°K.&lt;/div&gt;
Recent advances in ultra-compact highly nonlinear fibers and their applications (2007)

In this paper, we review design and characteristics of recently reported down-sized highly nonlinear fibers (HNLFs) and ultra-compact HNLF modules. A certain feasibility of down-sized HNLFs is confirmed through optical and mechanical evaluation. Furthermore, not only down-sizing, new attractive application is realized by utilizing unique mechanical characteristics of down-sized HNLF. (4 pages)
Global Timing Control with Applications to Tape Storage Channels (2008)

A new approach is introduced for symbol synchronization in multi-channel data storage systems called global timing control (GTC). Applying results from optimum filtering theory to the state-space model of the timing process in multichannel data storage systems, a multi-input multi-output PLL solution is derived. Efficient implementations are developed through simplifications of the optimal solution obtained. The performance of the GTC technique is analyzed using actual read- back waveforms captured in commercial tape drive systems. The results demonstrate the impressive robustness of GTC and its excellent resilience against loss-of-lock phenomena.

Direct measurements of vibrational predissociation of p-difluorobenzene–argon (1988)

We have measured rates of vibrational predissociation from 12 vibrational levels of S1 p-difluorobenzene–argon (pDFB–Ar) by time-resolved two-color multiphoton ionization. Three features of our results are particularly surprising. First, the vibrational predissociation rate does not necessarily increase with additional quanta in a given ring vibrational mode. Second, direct excitation of the presumed reaction coordinate, the van der Waals stretch, may decrease the vibrational predissociation rate. Third, pDFB mode 8 (mode 16a in the Wilson notation) shows a large vibrational frequency shift upon complexation, as in other aromatic-argon complexes, but in pDFB it is at most weakly active in vibrational predissociation, in striking contrast to the other systems. These results are inconsistent with available simple theories of vibrational predissociation. We also find that the vibrational predissociation lifetime exceeds 2.7 ns even at 1634 cm−1 excess vibrational energy, where rapid vibrational energy redistribution has been predicted. Where direct comparison is possible, the rates we measure are about 40% lower than those obtained in time-integrated experiments by Parmenter and co-workers.
Preparation and study of alkyl carbamylated polyrotaxanes with large hysteresis during sol–gel phase transition (2011)

Ethyl carbamylated polyrotaxane (ECPR) and propyl carbamylated polyrotaxane (PCPR) were prepared based on the reactions between ethyl/propyl isocyanate and polyrotaxane (PR) in anhydrous DMSO under an argon atmosphere. By changing the alkyl type and substitution ratio, the PR derivative with good water-solubility was obtained and its solutions showed reversible sol–gel phase transition. During the heating process, transition temperature from sol to gel decreased from 32 °C to 18 °C with increasing the solution concentration from 2.44% to 13.5%, while in the cooling process, all the gels with various concentration did not turn into sols until the temperature decreased to 1 °C, exhibiting large hysteresis between heating and cooling.
Interaction between two mitogen‐activated protein kinases during tobacco defense signaling (2003)

Plant mitogen-activated protein kinases (MAPKs) represented by tobacco wounding-induced protein kinase (WIPK) have unique regulation at the level of transcription in response to stresses. By using transcriptional and translational inhibitors, it has been shown previously that WIPK gene expression and de novo protein synthesis are required for the high-level activity of WIPK in cells treated with elicitins from Phytophthora spp. However, regulation of WIPK expression and the role(s) of WIPK in plant disease resistance are unknown. In this report, we demonstrate that WIPK gene transcription is regulated by phosphorylation and de-phosphorylation events. Interestingly, salicylic acid-induced protein kinase (SIPK) was identified as the kinase involved in regulating WIPK gene expression based on both gain-of-function and loss-of-function analyses. This finding revealed an additional level of interaction between SIPK and WIPK, which share an upstream MAPKK, NtMEK2. Depending on whether WIPK shares its downstream targets with SIPK, it could either function as a positive feed-forward regulator of SIPK or initiate a new pathway. Consistent with the first scenario, co-expression of WIPK with the active mutant of NtMEK2 leads to accelerated hypersensitive response (HR)-like cell death in which SIPK also plays a role. Mutagenesis analysis revealed that the conserved common docking domain in WIPK is required for its function. Together with prior reports that (i) WIPK is activated in NN tobacco infected with tobacco mosaic virus, and (ii) PVX virus-induced gene silencing of WIPK attenuated N gene-mediated resistance, we concluded that WIPK plays a positive role in plant disease resistance, possibly through accelerating the pathogen-induced HR cell death.

Validity of Clinical Information from a Maternity Survey (1997)

This research was designed to validate data collected through a survey--an inexpensive way to provide information for quality measurement. The survey was sent to health maintenance organization (HMO) enrollees who had given birth(s) between October 1, 1994, and May 31, 1995. The responses were compared with the medical records. A sample of 407 women was randomly selected from the completed surveys. Medical records were reviewed for 89.9% (362/407) of the sample based on medical record availability. Over 98% of responses agreed with the medical record information regarding whether there were cesarean sections for previous deliveries (kappa = 1.0), cesarean section for recent delivery (kappa = 0.95), and vaginal birth after cesarean section (kappa = 0.96). Over 99% of the mothers agreed with the information regarding whether the newborn birth weight was under 2500 g (kappa = 0.91). The findings strongly support the validation of this instrument. Using this validated instrument enables health plans to cost-effectively obtain crucial information.
Blue-Violet Bow-Tie Self-Pulsating Laser Diode with a Peak Power of 20 W and a Pulse Energy of 310 pJ (2010)

We generated single-transverse-mode optical pulses with a peak power of 20 W and a pulse energy of 310 pJ from a bow-tie self-pulsating GaN-based laser diode (SP-LD) under dc bias operation. Introducing the bow-tie structure, which has flared waveguides in both gain regions, increased the average output power and the optical pulse energy. An incorporation of the bow-tie structure resulted in an improved optical peak power that was twice that of a non tapered SP-LD.
Partially-Hydrophobized Polymer Particles Derived from N,N-Dimethylaminopropylacrylamide for Endotoxin Removal from Acidic Protein Solution. (1996)

Novel copolymeric adsorbents for the selective removal of endotoxin from an acidic protein solution were prepared. The adsorbents comprise spherical copolymers derived from N,N-dimethylaminopropylacrylamide (DMAPAA) and divinylbenzene (DVB). When the molar ratio of DMAPAA to DVB was 80/20 (amino-group content: 5.1 meq/g) and the pore size (molecular mass exclusion of polysaccharide, Mlim) was 4000 to 10000, DMAPAA/DVB showed high endotoxin-adsorbing activity at pH 5.0 to 9.0 and ionic strengths of mu = 0.05 to 0.4. The capacity of the adsorbent (Mlim: 4000) was 390 micrograms of endotoxin (lipopolysaccharide purified from E. coli O111:B4) per ml of the adsorbent using the batchwise method. The apparent dissociation constant between endotoxin and the adsorbent was 2.2 x 10(-12) M. On the other hand, the adsorption of bovine serum albumin, an acidic protein, by the adsorbent increased with an increase in Mlim from 4000 to 10000, but decreased with an increase in ionic strength (mu) from 0.05 to 0.2. As a result, DMAPAA/DVB (80/20) (Mlim: 4000) selectively removed endotoxin from various acidic protein solutions at pH 7.0 and mu = 0.05. The residual concentration of endotoxin in the protein solution always decreased to a concentration lower than 0.1 ng/ml, and recovery of the protein was more than 97%.
Pickup suppression in Sagnac-based fiber-optic acoustic sensor array (2005)

Large-scale acoustic fiber sensor arrays consisting of hundreds of hydrophones distributed along kilometers-long fiber buses are required for applications such as undersea oil exploration. Sagnac-based Sensor Arrays (SSAs) exhibit attractive performance; however the acoustic wave incident on the buses generates a pickup signal that can swamp the signals from the hydrophones. We propose, model, and demonstrate a simple technique for reducing this unwanted pickup by periodically inserting null sensors in the buses instead of hydrophones, so the pickup signal is measured at different locations along the buses. The signal from the null sensor (pickup only) is then subtracted from the signal seen by the adjacent hydrophone (true signal and pickup) to recover the true hydrophone signal. This paper describes in detail the signal processing steps used to perform this recovery. Applied to an experimental two-rung SSA, this technique produced a -18.6 dB pickup suppression for a pickup amplitude as large as 0.44 rad and signal amplitudes up to 0.44 rad, and -15 dB for a signal as large as 0.88 rad. These values are limited by the accuracy of the 8-bit data acquisition and/or electronic noise. With a low-noise 12-bit data acquisition, the pickup suppression for small signal amplitudes is predicted to be -35 dB. This work makes headway towards practical SSAs.
Group Activity Recognition to Support Collaboration in Creative Digital Space (2019)

In order to orchestrate collaborative group work, such as a brainstorming workshop or active learning class, a facilitator must monitor all groups simultaneously. In this paper, we propose a method for recognizing group activities, based on machine learning, where the input features are derived from the analysis of raw system events generated by a collaboration system known as "creative digital space" that we developed before. To verify the effectiveness of the proposed method, we also evaluated the results obtained by using the test data collected from active learning classes.

TalkBack (2003)

Current asynchronous voice messaging interfaces, like voicemail, fail to take advantage of our conversational skills. TalkBack restores conversational turn-taking to voicemail retrieval by dividing voice messages into smaller sections based on the most significant silent and filled pauses and pausing after each to record a response. The responses are composed into a reply, alternating with snippets of the original message for context. TalkBack is built into a digital picture frame; the recipient touches a picture of the caller to hear each segment of the message in turn. The minimal interface models synchronous interaction and facilitates asynchronous voice messaging. TalkBack can also present a voice-annotated slide show which it receives over the Internet.
Fabrication of single-mode chalcogenide optical fiber (1998)

Long lengths (>150 m) of single-mode chalcogenide optical fiber were fabricated by a double crucible technique. Single-mode transmission through 10 m of continuous fiber was demonstrated using an F-center laser at 2.7 /spl mu/m. The optical loss of this fiber was measured by a standard cutback technique using an FTIR spectrometer and also using an F-center laser, A minimum loss of less than 1 dB/m was obtained.
Juvenile hormone synthesis by ring glands of the blowfly Lucilia cuprina (1997)

The major radiolabelled product released from ring gland and brain-ring gland complexes of third instar larval and pre-pupal stages of the sheep blowfly Lucilia cuprina upon incubation with L-[methyl-3H]methionine corresponded to one diastereomer of juvenile hormone III bisepoxide (JHB3). Endocrine glands incubated with the juvenile hormone precursor 2E,6E-farnesoic acid released increased quantities of JHB3, together with significant amounts of juvenile hormone III but not the isomeric methyl 2E-6,7-epoxyfarnesoate. Synthesis of JHB3 was developmentally and neurally regulated. Ring glands and brain-ring gland complexes from third instar larvae released more JHB3 than comparable preparations from pre-pupae, while isolated corpus allatum segments of the gland were more active than intact brain-gland complexes. These results reinforce the emerging status of JHB3 as the characteristic juvenile hormone of dipteran insects. Arch. Insect Biochem. Physiol. 34:239–253, 1997. © 1997 Wiley-Liss, Inc.
