ReCycle: (2007)

Process variation affects processor pipelines by making some stages slower and others faster, therefore exacerbating pipeline unbalance. This reduces the frequency attainable by the pipeline. To improve performance, this paper proposes ReCycle, an architectural framework that comprehensively applies cycle time stealing to the pipeline - transferring the time slack of the faster stages to the slow ones by skewing clock arrival times to latching elements after fabrication. As a result, the pipeline can be clocked with a period equal to the average stage delay rather than the longest one. In addition, ReCycle's frequency gains are enhanced with Donor stages, which are empty stages added to "donate" slack to the slow stages. Finally, ReCycle can also convert slack into power reductions. For a 17FO4 pipeline, ReCycle increases the frequency by 12% and the application performance by 9% on average. Combining ReCycle and donor stages delivers improvements of 36% in frequency and 15% in performance onaverage, completely reclaiming the performance losses due to variation.
Comprehensive PMML preprocessing in KNIME (2011)

This paper describes PMML extensions for the modular open source data analytics platform KNIME adding pre-processing support and the ability to edit existing PMML code. It is also shown how the PMML model representation in KNIME can be used within meta learning schemes such as boosting and bagging.
Modulation of Immunoregulatory Properties of Mesenchymal Stromal Cells by Toll‐Like Receptors: Potential Applications on GVHD (2016)

In the last decade, the immunomodulatory properties of mesenchymal stromal cells (MSCs) have attracted a lot of attention, due to their potential applicability in the treatment of graft-versus-host disease (GVHD), a condition frequently associated with opportunistic infections. The present review addresses how Pathogen-Associated Molecular Patterns (PAMPS) modulate the immunosuppressive phenotype of human MSCs by signaling through Toll-like receptors (TLRs). Overall, we observed that regardless of the source tissue, human MSCs express TLR2, TLR3, TLR4, and TLR9. Stimulation of distinct TLRs on MSCs elicits distinct inflammatory signaling pathways, differentially influencing the expression of inflammatory factors and the ability of MSCs to suppress the proliferation of immune system cells. The capacity to enhance the immunosuppressive phenotype of MSCs through TLRs stimulation might be properly elucidated in order to improve the MSC-based immunotherapy against GVHD.
Transposition of a reconstructed <i>Harbinger</i> element in human cells and functional homology with two transposon-derived cellular genes (2008)

Ancient, inactive copies of transposable elements of the PIF/Harbinger superfamily have been described in vertebrates. We reconstructed components of the Harbinger3_DR transposon in zebrafish, including a transposase and a second, transposon-encoded protein that has a Myb-like trihelix domain. The reconstructed Harbinger transposon shows efficient cut-and-paste transposition in human cells and preferentially inserts into a 15-bp consensus target sequence. The Myb-like protein is required for transposition and physically interacts with the N-terminal region of the transposase via its C-terminal domain. The Myb-like protein enables transposition in part by promoting nuclear import of the transposase, by directly binding to subterminal regions of the transposon, and by recruiting the transposase to the transposon ends. We investigated the functions of two transposon-derived human proteins: HARBI1, a domesticated transposase-derived protein, and NAIF1, which contains a trihelix motif similar to that described in the Myb-like protein. Physical interaction, subcellular localization, and DNA-binding activities of HARBI1 and NAIF1 suggest strong functional homologies between the Harbinger3_DR system and their related, host-encoded counterparts. The Harbinger transposon will serve as a useful experimental system for transposon biology and for investigating the enzymatic functions of domesticated, transposon-derived cellular genes.
The isolation and characterization of abscisic acid‐insensitive mutants of <i>Arabidopsis thaliana</i> (1984)

Abscisic acid (ABA) insensitive mutants of Arabidopsis thaliana (L.) Heynh. were isolated by selecting plants which grew well on a medium containing 10 μ M ABA. From the progeny of approximately 3500 mutagen‐treated seeds, five mutants of at least three different loci were isolated. Three mutants were characterized, moreover, by a reduced seed dormancy and by symptoms of withering, indicating disturbed water relations and, therefore, resembled phenotypically the ABA‐deficient mutants we described earlier in this species. Two mutants showed in addition only a reduction of seed dormancy. Compared to wild type, all mutants showed similar or increased levels of endogenous ABA in developing seeds and fruits (siliquae). The role of the different genes involved is discussed in relation to the mechanism of ABA action.
Quantification of tumor tissue populations by multispectral analysis (2004)

Abstract Tumor heterogeneity complicates the quantification of a therapeutic response by MRI. To address this issue, a novel approach has been developed that combines MR diffusion imaging with multispectral (MS) analysis to quantify tumor tissue populations. K‐means (KM) clustering of the apparent diffusion coefficient (ADC), T 2 , and proton density ( M 0 ) was employed to estimate the volumes of viable tumor tissue, necrosis, and neighboring subcutaneous adipose tissue in a human colorectal tumor xenograft mouse model. In a second set of experiments, the temporal evolution of the MS tissue classes in response to therapeutic intervention Apo2L/TRAIL and CPT‐11 was observed. The multiple parameters played complementary roles in identifying the various tissues. The ADC was the dominant parameter for identifying regions of necrosis, whereas T 2 identified two necrotic subpopulations, and M 0 contributed to the differentiation of viable tumor from subcutaneous adipose tissue. MS viable tumor estimates (mean volume = 275 ± 147 mm 3 ) were highly correlated (r = 0.81, P < 0.01) with histological estimates (117 ± 51 mm 3 ). In the treatment study, MS viable tumor volume (at day 10) was 77 ± 67 mm 3 for the Apo2L/TRAIL+CPT‐11 group, and was significantly reduced relative to the control group (292 ± 127 mm 3 , P < 0.01). This method shows promise as a means of detecting an early therapeutic response in vivo. Magn Reson Med 51:542–551, 2004. © 2004 Wiley‐Liss, Inc.
Benefits and schemes of prefetching from cloud to fog networks (2017)

Cloud data services have been in rapidly increasing demand by mobile users, but such services often face the problem of lowered QoS due to the lengthy delay of transmitting large amount of data all the way from the cloud server to the mobile client. In this paper, we propose a prefetching-based approach which utilizes the spare bandwidth and storage space of fog networks to prefetch data files from cloud data servers to edge servers in the fog networks that are much closer to the mobile users, thereby providing better data delivery in terms of transmission delay. We propose six possible prefetching schemes which are designed based on different needs of a priori knowledge about the mobile user's file access patterns. Observing that some prefetching scheme performs better than other schemes when facing a particular type of access pattern, our framework also allows the cloud server and edge servers to dynamically switch to another prefetching scheme if the current prefetching scheme does not fit well with the user's access pattern. We use simulations to evaluate the performance of our proposed prefetching schemes, and the results show that each prefetching scheme can reduce transmission delay, and that the dynamic scheme switching can help improve the performance in terms of prefetching precision and recall ratios.
How to Prepare the Accounting Entry on the Basis of Capital Movement (2006)

It is well known that economic transactions must be prepared the accounting entries before they are registered in account books. Therefore, it's the most important procedure in the whole accounting work to prepare the accounting entries correctly. This paper puts forward how to prepare the accounting entry on the basis of capital movement because the traditional method is so complex, abstract and incomprehensible to be mastered by beginners. The research shows that the new method proposed in the paper is very direct, pictorial, and concrete. It is very easy to be mastered by a beginner of accounting.
ENU-induced in vitro neoplastic transformation of rat mammary epithelial cells. (1992)

Normal mammary epithelial cells, originating from female Sprague-Dawley rats, were grown in Dulbecco's Modified Eagles Medium containing 25% horse serum and hormone supplements. Once established as an epithelial cell culture, the cells were treated with N-ethyl-N-nitrosourea (ENU) in various doses (25-500 ug/ml) to study the process of in vitro mammary epithelial cell neoplastic transformation. The ENU-treatment of primary mammary epithelial cell culture resulted in a sequence of phenotypic changes, termed stages I-V. The rat mammary epithelial cells, after a period of approximately 30 days post-ENU exposure, showed a marked proliferation of morphologically altered cells which formed multi-layered colonies. Subsequently, these cells acquired the capacity to form colonies in soft agar and eventually produced a high yield of palpable tumors when inoculated into newborn female isologous hosts or female athymic nude mice. The immediate effect of ENU on these cells was monitored by measurement of cellular DNA content, unscheduled DNA synthesis, cell proliferation and chromosomal aberrations. The ENU effect on cell proliferation and DNA synthesis was dose dependent; doses greater than 100 ug/ml reduced the cell number and DNA synthesis. Cytofluorometric histograms of non-ENU-treated rat mammary epithelial cells showed a near diploid population of cells. The ENU exposed cells subsequently became hyperdiploid (24-72 hours after ENU) and then regained their near diploid pattern at 120 hours after ENU exposure. The ENU-treated cells also showed a second peak of cells with DNA content in the tetraploid and octaploid range at 24-72 hours after ENU exposure. Single chromatid breaks, isochromatid breaks, chromosomal exchanges, multiple chromosomal breaks and double minutes were among the chromosomal aberrations seen in ENU-treated cells. Most of the chromosomal aberrations peaked at 6 hours post-ENU exposure. The ENU-induced model of in vitro meplastic transformation of rat mammary epithelium as described in this communication appears to provide a good model for the systematic study of the early critical cellular events prerequisite to this carcinogenic process.
Cyclopentadienyl complexes with transition metal – main group metal bonds. VII. <sup>207</sup>Pb and <sup>95</sup>Mo nuclear magnetic resonance studies on molybdenum and tungsten complexes [(η<sup>5</sup>-C<sub>5</sub>H<sub>5</sub>)(CO)<sub>3</sub>M]<sub><i>n</i></sub>PbR<sub>4−<i>n</i></sub> (<i>n</i> = 1, R = Me, Et, Ph; <i>n</i> = 2, R = Ph) (1987)

Nuclear magnetic resonance measurements of metallic nuclei (δ 207 Pb, δ 95 Mo, and 1 J(W–Pb)) have been carried out on dimetallic Cp(CO) 3 MPbR 3 (M = Mo, W; R = Me, Et, Ph) and trimetallic [Cp(CO) 3 M] 2 PbPh 2 (M = Mo, W) complexes. 207 Pb chemical shifts increase in the sequence PbEt 3 < PbMe 3 < PbPh 3 and are observed at higher fields in the tungsten compounds than in the molybdenum ones. It is suggested that both paramagnetic and diamagnetic contributions determine the overall shielding of lead, and that the higher field resonances of 207 Pb in the case of W–Pb compounds are due to an efficacious operation of the Z/r dependent diamagnetic term (higher atomic number Z of tungsten and roughly the same Mo–Pb and W–Pb distances resulting from the 4f level induced lanthanide contraction). 95 Mo chemical shifts (−1838 to −2007 ppm) lie in the region typical of the molybdenum – main group metal bonded complexes but at lower fields than in the corresponding Mo–Sn compounds. It is concluded from this observation that the Z/r dependent diamagnetic contribution does not operate efficaciously for 95 Mo shieldings, which are hence primarily dominated by the paramagnetic term. The nature of metal–metal interactions is discussed.
The Aging Effect on Intraocular Pressure in an Apparently Normal Population (1984)

Statistical analysis of intraocular pressure was conducted on approximately 200,000 healthy subjects who were examined at the Aichi Prefectural Center of Health Care in Nagoya, Japan, during the last decade. The IOP was estimated with either Schl øtz or noncontact tonometers, which consistently showed a decreasing tendency of IOP with age in both sexes. Multivariate analysis on systemic values disclosed that obesity, systolic BP, and age were the most influential factors of IOP. Stratification of the sample by systolic BP, obesity index, and age indicated that young, obese, and hypertensive subjects had the highest IOP, while old, lean, and hypotensive subjects showed the lowest IOP. It was confirmed that the IOP is physiologically maintained by a counterbalance between the IOP-lowering effect of age and the IOP-raising effects of obesity and systolic hypertension, which are largely age dependent.
Noise induced time interval measurement biases (2003)

Time jitter in the output fronts of hysteretic triggers is not the only effect of additive noise. An average leading time bias error can be observed when large bandwidth noise is added to a poor slope signal. Time jitter is shown to be a possible limitation to the accuracy of high precision time interval measurements, as the average switching time is always before the zero crossing of the ideal noiseless analog signal. The resulting bias in the start-stop type of measurements, in which a noisy signal is compared to a reference, is shown to depend on S/N ratio and on noise bandwidth. An experimental evaluation of this effect is reported, based on time interval measurements in which noise is added to a sinewave signal.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
High Speed 4 kbit Static RAM with Silicide Coated Wiring (1981)

A high speed, fully static, and 4096 word by one bit Random Access Memory has been developed, using short channel MOSFETs with platinum silicide (PtSi) coated polysilicon gate and PtSi coated n + diffusion layer as low resistive wiring. The present RAM was operated on a single 5±1 volt power supply. Its typical performances are 21 nsec address access time, 23 nsec chip select access time, 500 mW operating power and 50 mW stand by power.
Ultrathin Assemblies on Flexible Substrates (2006)

Miniaturization enforcement of electronic modules in complex as well as low cost applications is the driving force to integrate flip chip technology in common surface mount device processes. The use of flexible substrates enables a large variety of geometric possibilities including folding and bending. On the one hand there are numerous low cost applications for this technology such as smart cards and smart labels, on the other hand flexible substrates offer a wide potential for highly complex folded packages and 3D modules. Thinned silicon chips with subsequent very thin bumps mounted on flexible substrates open up new dimensions in packaging technologies. They can be integrated even in thin products, e.g. documents or stacked to low profile 3D modules. Beside the geometrical aspects the parasitic influences of silicon material can be eliminated by thinning of the wafers. This advantage is of great interest for applications in the GHz-area for example for GPS modules.
EPA but Not DHA Appears To Be Responsible for the Efficacy of Omega-3 Long Chain Polyunsaturated Fatty Acid Supplementation in Depression: Evidence from a Meta-Analysis of Randomized Controlled Trials (2009)

The current meta-analysis provides evidence that EPA may be more efficacious than DHA in treating depression. However, owing to the identified limitations of the included studies, larger, well-designed, randomized controlled trials of sufficient duration are needed to confirm these findings.
Improvements in purification of silver nanowires by decantation and fabrication of flexible transparent electrodes. Application to capacitive touch sensors (2013)

Transparent flexible electrodes made of metallic nanowires, and in particular silver nanowires (AgNWs), appear as an extremely promising alternative to transparent conductive oxides for future optoelectronic devices. Though significant progresses have been made the last few years, there is still some room for improvement regarding the synthesis of high quality silver nanowire solutions and fabrication process of high performance electrodes. We show that the commonly used purification process can be greatly simplified through decantation. Using this process it is possible to fabricate flexible electrodes by spray coating with sheet resistance lower than 25 Ω sq⁻¹ at 90% transparency in the visible spectrum. These electrodes were used to fabricate an operative transparent flexible touch screen. To our knowledge this is the first reported AgNW based touch sensor relying on capacitive technology.
Temperature Dependence of Infrared Dispersion in Ionic Crystals LiF and MgO (1966)

Infrared-reflectivity measurements were made from 200 ${\mathrm{cm}}^{\ensuremath{-}1}$ to 800 ${\mathrm{cm}}^{\ensuremath{-}1}$ at temperatures ranging from 7.5 to 1060\ifmmode^\circ\else\textdegree\fi{}K for LiF and from 8 to 1950\ifmmode^\circ\else\textdegree\fi{}K for MgO. The reflection spectra were analyzed by means of a two-resonance damped-oscillator model, and the calculated optical properties are presented. Dielectric dispersion theory is reviewed and it is shown that all the major theories discussed give identical results for the susceptibility when evaluated at the reststrahlen frequency but differ from one another at other frequencies. The damping constant $\ensuremath{\gamma}$ for LiF and MgO in the high-temperature limit ($h{\ensuremath{\nu}}_{1}<\mathrm{kT}$) agrees reasonably well with the formula suggested by Maradudin and Wallis, but discrepancies seem to appear in the low-temperature limit ($h{\ensuremath{\nu}}_{1}>\mathrm{kT}$). The general behavior of the extinction coefficient in the wings of the absorption region is consistent with the notion of continuous absorption produced by multiphonon processes. The shift of the long-wavelength optical-mode frequencies of LiF, MgO, and RbI with temperature is discussed in terms of the volume and other anharmonic effects. The anharmonic part of the frequency shift is found to agree qualitatively with the theory of Maradudin and Fein.
Clinical Studies of Biofield Therapies: Summary, Methodological Challenges, and Recommendations (2015)

Biofield therapies are noninvasive therapies in which the practitioner explicitly works with a client's biofield (interacting fields of energy and information that surround living systems) to stimulate healing responses in patients. While the practice of biofield therapies has existed in Eastern and Western cultures for thousands of years, empirical research on the effectiveness of biofield therapies is still relatively nascent. In this article, we provide a summary of the state of the evidence for biofield therapies for a number of different clinical conditions. We note specific methodological issues for research in biofield therapies that need to be addressed (including practitioner-based, outcomes-based, and research design considerations), as well as provide a list of suggested next steps for biofield researchers to consider.
Electrophoresis of RNA Denatured with Glyoxal or Formaldehyde (2003)

The first successful method for electrophoretic analysis of the full size range of cellular RNA molecules was described by Loening (1), and its introduction allowed for major advances, most particularly in the molecular biology of eukaryotic organisms. The method had, nevertheless, two significant disadvantages in that the gels (composed of acrylamide at very low concentrations) were mechanically fragile, and the migration of RNA molecules did not necessarily reflect their size because RNA secondary structure was not disrupted.
An autonomous SRAM with on-chip sensors in an 80nm double stacked cell technology (2005)

An active solution to overcome the uncertainty and fluctuation in nano technology SRAM is introduced. It automatically adapts SRAM's operation optimized for the process variation and operating environments by using on-chip timer, temperature sensor, substrate noise manager and leakage current monitor. A test SRAM chip fabricated with an 80nm SRAM process, shows that average power consumption is reduced by 9%, and the standard deviation decreases by 58%.
RF front end for a 4.1 Tesla clinical NMR spectrometer (2002)

With increased signal-to-noise, spatial, temporal, and spectral resolution, blood oxygenation level effects, and other benefits of high fields NMR, 4T NMR systems enhance the potential for medical science and diagnostics from multinuclear imaging and spectroscopy of humans. A new NMR spectrometer is needed however. The magnet aside, the key difference between present clinical or animal systems, and 4T+ clinical systems is the RF front end. Including the power amplifier, transmit/receive (T/R) switch, preamplifier, and RF coils, the front end is required to operate at power levels, bandwidths, and circuit lengths unique in the NMR field. New technology has been developed for these components to optimize the performance of the spectrometer. For broader spectral bandwidths, and to compensate for chemical shift dispersion error, two 15 kW solid state amplifiers have been developed for implementation on a "home-built" 4.1 T clinical system. A stripline transformed, nonmagnetic, tuned GaAsFET preamp has been built for achieving high gain and low noise at the RF coil. A nonmagnetic dual quadrature hybrid-PIN diode T/R switch was developed to isolate the RF power amplifier from the receiver. New high frequency coils have made use of tuned cavities and transmission lines.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
