Hot Workability Of High Strength Low Alloy Steels (2013)

The hot deformation behavior of high strength low alloy (HSLA) steels with different chemical compositions under hot working conditions in the temperature range of 900 to 1100℃ and strain rate range from 0.1 to 10 s-1 has been studied by performing a series of hot compression tests. The dynamic materials model has been employed for developing the processing maps, which show variation of the efficiency of power dissipation with temperature and strain rate. Also the Kumar-s model has been used for developing the instability map, which shows variation of the instability for plastic deformation with temperature and strain rate. The efficiency of power dissipation increased with decreasing strain rate and increasing temperature in the steel with higher Cr and Ti content. High efficiency of power dissipation over 20 % was obtained at a finite strain level of 0.1 under the conditions of strain rate lower than 1 s-1 and temperature higher than 1050 ℃ . Plastic instability was expected in the regime of temperatures lower than 1000 ℃ and strain rate lower than 0.3 s-1. Steel with lower Cr and Ti contents showed high efficiency of power dissipation at higher strain rate and lower temperature conditions.
p73 induction after DNA damage is regulated by checkpoint kinases Chk1 and Chk2 (2004)

The checkpoint kinases Chk1 and Chk2 are central to the induction of cell cycle arrest, DNA repair, and apoptosis as elements in the DNA-damage checkpoint. We report here that in several human tumor cell lines, Chk1 and Chk2 control the induction of the p53 related transcription factor p73 in response to DNA damage. Multiple experimental systems were used to show that interference with or augmentation of Chk1 or Chk2 signaling strongly impacts p73 accumulation. Furthermore, Chk1 and Chk2 control p73 mRNA accumulation after DNA damage. We demonstrate as well that E2F1 directs p73 expression in the presence and absence of DNA damage. Chk1 and Chk2, in turn, are vital to E2F1 stabilization and activity after genotoxic stress. Thus, Chk1, Chk2, E2F1, and p73 function in a pathway mediating p53-independent cell death produced by cytotoxic drugs. Since p53 is often obviated through mutation as a cellular port for anticancer intervention, this pathway controlling p53 autonomous pro-apoptotic signaling is of potential therapeutic importance.
Glial nuclear aggregates of superoxide dismutase-1 are regularly present in patients with amyotrophic lateral sclerosis (2011)

The most common cause of amyotrophic lateral sclerosis (ALS) is mutations in superoxide dismutase-1 (SOD1). Since there is evidence for the involvement of non-neuronal cells in ALS, we searched for signs of SOD1 abnormalities focusing on glia. Spinal cords from nine ALS patients carrying SOD1 mutations, 51 patients with sporadic or familial ALS who lacked such mutations, and 46 controls were examined by immunohistochemistry. A set of anti-peptide antibodies with specificity for misfolded SOD1 species was used. Misfolded SOD1 in the form of granular aggregates was regularly detected in the nuclei of ventral horn astrocytes, microglia, and oligodendrocytes in ALS patients carrying or lacking SOD1 mutations. There was negligible staining in neurodegenerative and non-neurological controls. Misfolded SOD1 appeared occasionally also in nuclei of motoneurons of ALS patients. The results suggest that misfolded SOD1 present in glial and motoneuron nuclei may generally be involved in ALS pathogenesis.

A New Model for the Equilibrium Shape of Raindrops (1987)

The equilibrium shape of raindrops has been determined from Laplace's equation using an internal hydrostatic pressure with an external aerodynamic pressure based on measurements for a sphere but adjusted for the effect of distortion. The drop shape was calculated by integration from the upper pole with the initial curvature determined by iteration on the drop volume. The shape was closed at the lower pole by adjusting either the pressure drag or the drop weight to achieve an overall force balance. Model results provide bounds on the axis ratio of raindrops with an uncertainty of about 1% and very good agreement with extensive wind tunnel measurements for moderate to large water drops. The model yields the peculiar asymmetric shape of raindrops: a singly curved surface with a flattened base and a maximum curvature just below the major axis. A close match was found between model shapes and profiles obtained from photos of water drops for diameters up to 5 mm. Coefficients are provided for computing raindrop shape as a cosine series distortion on a sphere. In contrast to earlier models of raindrop shape for the oblate spheroid response to gravity (Green, Beard) or the perturbation response to the aerodynamic pressure for a sphere (Imai, Savic, Pruppacher and Pitter), the present model provides the appropriate large amplitude response to both the hydrostatic and aerodynamic pressures modified for distortion. In addition, the new model can be readily extended to include other pressures such as an electric stress.
Limbal stem cell deficiency: concept, aetiology, clinical presentation, diagnosis and management. (2000)

Defects in renewal and repair of ocular surface as a result of limbal stem cell deficiency are now known to cause varying ocular surface morbidity including persistent photophobia, repeated and persistent surface breakdown and overt conjunctivalisation of the cornea. Ocular conditions with abnormalities of ocular surface repair include pterygium, limbal tumours, aniridia, severe scarring following burns, cicatricial pemphigoid and Stevens-Johnson Syndrome, sequelae of mustard gas exposure and Herpes simplex epithelial disease, radiation keratopathy, contact lens induced keratopathy, neuroparalytic keratitis and drug toxicity. Restoring ocular health in these eyes has traditionally been frustrating. An understanding of these intricate cell renewal and maintenance processes has spurred the evolution in recent years of new treatment methods for several blinding diseases of the anterior segment; many more exciting modalities are in the offing. However, there is inadequate awareness among ophthalmologists about the current principles of management of ocular surface disorders. The purpose of this article is to help elucidate the important principles and current treatment methods relevant to ocular surface disorders.

XIFER: A Software Diversity Tool Against Code-Reuse Attacks (2012)

The enormous growth of mobile devices and their app markets has raised many security and privacy concerns. Runtime attacks seem to be a major threat, in particular, codereuse attacks that do not require any external code injection (e.g., return-to-libc or return-oriented programming). We present, for the first time, a code transformation tool that completely mitigates code-reuse attacks by applying software diversity to the binary at runtime. Our tool XIFER (1) randomly diversifies the code of an application over the entire memory for each invocation, (2) requires no source code or any static analysis, (3) can be applied to both Intel x86 and ARM Linux executables, and (4) induces a negligible runtime overhead of only 1 % in average.
Functional homologs of fungal metallothionein genes from Arabidopsis. (1994)

Metallothioneins (MTs) are cysteine-rich proteins required for heavy metal tolerance in animals and fungi. Two cDNAs encoding proteins with homology to animal and fungal MTs have been isolated from Arabidopsis. The genes represented by these cDNAs are referred to as MT1 and MT2. When expressed in an MT-deficient (cup1 delta) mutant of yeast, both MT1 and MT2 complemented the cup1 delta mutation, providing a high level of resistance to CuSO4 and moderate resistance to CdSO4. Although the MT-deficient yeast was not viable in the presence of either 300 microM CuSO4 or 5 microM CdSO4, cells expressing MT1 were able to grow in medium supplemented with 3 mM CuSO4 and 10 microM CdSO4, and those expressing MT2 grew in the presence of 3 mM CuSO4 and 100 microM CdSO4. In plants, MT1 mRNA was more abundant in roots and dark-grown seedlings than in leaves. In contrast, MT2 mRNA accumulated more in leaves than in either roots or darkgrown seedlings. MT2 mRNA was strongly induced in seedlings by CuSO4, but only slightly by CdSO4 or ZnSO4. However, MT1 mRNA was induced by CuSO4 in excised leaves that were submerged in medium. These results indicated that Arabidopsis MT genes are involved in copper tolerance. Plants also synthesized metal binding phytochelatins (poly[gamma-glutamylcysteine]glycine) when exposed to heavy metals. The results presented here argue against the hypothesis that phytochelatins are the sole molecules involved in heavy metal tolerance in plants. We conclude that Arabidopsis MT1 and MT2 are functional homologs of yeast MT.
Highly-linear transconductor cell realised by double MOS transistor differential pairs (1990)

A novel scheme for tunable transconductance cells with high linearity is described. The proposed configuration is realised by double MOS transistor differential pairs with two independent linear outputs, which can be employed separately as well as in a parallel or cross-coupled connection. A trans-conductance amplifier is shown as an application example. Computer simulation is used to verify the concept.
<i>Vipp1</i> deletion mutant of <i>Synechocystis</i> : A connection between bacterial phage shock and thylakoid biogenesis? (2001)

Plant chloroplasts originated from an endosymbiotic event by which an ancestor of contemporary cyanobacteria was engulfed by an early eukaryotic cell and then transformed into an organelle. Oxygenic photosynthesis is the specific feature of cyanobacteria and chloroplasts, and the photosynthetic machinery resides in an internal membrane system, the thylakoids. The origin and genesis of thylakoid membranes, which are essential for oxygenic photosynthesis, are still an enigma. Vipp1 (vesicle-inducing protein in plastids 1) is a protein located in both the inner envelope and the thylakoids of Pisum sativum and Arabidopsis thaliana. In Arabidopsis disruption of the VIPP1 gene severely affects the plant's ability to form properly structured thylakoids and as a consequence to carry out photosynthesis. In contrast, Vipp1 in Synechocystis appears to be located exclusively in the plasma membrane. Yet, as in higher plants, disruption of the VIPP1 gene locus leads to the complete loss of thylakoid formation. So far VIPP1 genes are found only in organisms carrying out oxygenic photosynthesis. They share sequence homology with a subunit encoded by the bacterial phage shock operon (PspA) but differ from PspA by a C-terminal extension of about 30 amino acids. In two cyanobacteria, Synechocystis and Anabaena, both a VIPP1 and a pspA gene are present, and phylogenetic analysis indicates that VIPP1 originated from a gene duplication of the latter and thereafter acquired its new function. It also appears that the C-terminal extension that discriminates VIPP1 proteins from PspA is important for its function in thylakoid formation.
High-quality multi-pass image resampling (2010)

This paper develops a family of multi-pass image resampling algorithms that use one-dimensional filtering stages to achieve high-quality results at low computational cost. Our key insight is to perform a frequency-domain analysis to ensure that very little aliasing occurs at each stage in the multi-pass transform and to insert additional stages where necessary to ensure this. Using one-dimensional resampling enables the use of small resampling kernels, thus producing highly efficient algorithms. We compare our results with other state of the art software and hardware resampling algorithms.
Single-Shot Frequency-Resolved-Optical-Gating Device for Completely Measuring Nanosecond Laser Pulses in Time (2010)

We demonstrate a single-shot FROG for completely measuring nanosecond pulses. Its key innovation is its generation of distortionless pulse-front tilt of ~89.9°, yielding a ~10ns delay range. Using it, we measure ~ns Yb-fiber amplifier pulses.
Performance of enclosures for low-resonance high-compliance loudspeakers (1959)

This paper analyzes the low-frequency behavior of the vented loudspeaker enclosure and the pressure-tight closed box. Inherent interrelationships of the speaker-amplifier system Q, efficiency and response balance are discussed. A method is described for design of small enclosures with very low.resonance high-compliance loudspeakers. The author concludes that the vented enclosure can have greater acoustic output for a given amount of distortion, lower total harmonic, intermodulation, and transient distortion than a completely closed box of similar size.

Autocrine Production and Synergistic Growth-Promoting Activity of Interleukin-6 and Oncostatin M in a New Human Myeloma Cell Line TU-1 (2002)

Human myeloma cell lines are difficult to establish, and they usually originate from patients with extramedullary disease. We describe a new human myeloma cell line, TU-1, which was established from the bone marrow of a patient without extramedullary myeloma. The myeloma cells were initially maintained in a conditioned medium derived from another well-known myeloma cell line U-266. This conditioned medium contained interleukin-6 (IL-6) and oncostatin M (OSM), and possibly other unknown growth factors as well. In 3 months the TU-1 cell line proliferated autonomously and secreted IL-6 and OSM with a synergistic growth response. As we have previously shown the cell line acquired a p53 mutation in vitro, which may be an important factor causing autonomous proliferation. In patients with multiple myeloma OSM is frequently found in the serum and OSM has been associated with serum IL-6 and progressive disease. Our study demonstrates the close relationship of OSM and IL-6 also in vitro.
Integral solar cell covers by plasma activated CVD (1984)

Si0/sub 2/ covers as thick as 5 mils have been deposited directly on Si solar cells at temperatures below 150 /sup 0/ C with rates above 0.8 mils per hour by a novel plasma activated CVD process. Covers above 2 mils thick deform the cells excessively but do not delaminate. Stresses have been lowered by mixing A1/sub 2/O/sub 3/ into the cover through alterations in the CVD reactant gas mixture. In space power systems, these integral covers have promise for reducing system weight while simplifying cell assembly.
Advances in sensitivity encoding with arbitrary <i>k</i>‐space trajectories (2001)

New, efficient reconstruction procedures are proposed for sensitivity encoding (SENSE) with arbitrary k-space trajectories. The presented methods combine gridding principles with so-called conjugate-gradient iteration. In this fashion, the bulk of the work of reconstruction can be performed by fast Fourier transform (FFT), reducing the complexity of data processing to the same order of magnitude as in conventional gridding reconstruction. Using the proposed method, SENSE becomes practical with nonstandard k-space trajectories, enabling considerable scan time reduction with respect to mere gradient encoding. This is illustrated by imaging simulations with spiral, radial, and random k-space patterns. Simulations were also used for investigating the convergence behavior of the proposed algorithm and its dependence on the factor by which gradient encoding is reduced. The in vivo feasibility of non-Cartesian SENSE imaging with iterative reconstruction is demonstrated by examples of brain and cardiac imaging using spiral trajectories. In brain imaging with six receiver coils, the number of spiral interleaves was reduced by factors ranging from 2 to 6. In cardiac real-time imaging with four coils, spiral SENSE permitted reducing the scan time per image from 112 ms to 56 ms, thus doubling the frame-rate.
Improved phase-shifting method for automatic processing of moiré deflectograms (1998)

An improved moiré deflectometry phase-shifting technique is presented. A squared grating is used to multiplex the information of the deflections in two orthogonal directions in one image. This procedure avoids the need to rotate the gratings to obtain complete deflection information. However, the use of these gratings makes impossible the application of standard phase-shifting algorithms. Specifically, the problems associated with the nonsinusoidal profile of the moiré fringes and the low-modulation areas produced by the square gratings are solved. A modified moiré deflectometry phase-shifting method is designed to deal with these problems. In addition, a method to obtain the zero order of the prismatic effect is developed. The technique configures a complete and automatic method of mapping ray deflections. From them the refractive power maps can be derived. Experimental results obtained with a progressive-addition lens are shown.
Band selection in hyperspectral images based on the Fisher Linear Discriminant classifier (2010)

Hyperspectral data consists of three dimensional images; the third dimension is the spectral signature of each pixel. The question always arises: which bands should be used and how should they be weighted. In this paper, a band selection algorithm based on the Fisher's Linear Discriminant classifier (FLD) is implemented. An initial segmentation of the image into two different classes (gas and background) is used as an input for the FLD. The combination of bands to be used is selected based on the FLD results.
Decidable model checking of probabilistic hybrid automata (2000)

Hybrid automata offer a framework for the description of systems with both discrete and continuous components, such as digital technology embedded in an analogue environment. Traditional uses of hybrid automata express choice of transitions purely in terms of nondeterminism, abstracting potentially significant information concerning the relative likelihood of certain behaviours. To model such probabilistic information, we present a variant of hybrid automata augmented with discrete probability distributions. We concentrate on restricted subclasses of the model in order to obtain decidable model checking algorithms for properties expressed in probabilistic temporal logics.
Intermolecular zero-quantum coherence imaging of the human brain (2000)

The first intermolecular zero-quantum coherence (iZQC) MR images of the human brain at 4T are presented. To generate iZQC images, a modified echo-planar imaging pulse sequence was used which included an additional 45 degrees RF pulse and a correlation gradient. The observability and nonconventional contrast of human brain iZQC images at 4T is demonstrated. Axial images are presented for various pulse sequence parameters, and a zero-quantum relaxation map is obtained.
Enhancement of diamond nucleation by ultrasonic substrate abrasion with a mixture of metal and diamond particles (1995)

A method of surface treatment was found to enhance diamond chemical vapor deposition nucleation on nondiamond substrates such as Si, SiO2, and Al2O3. The nucleation density obtained by ultrasonic abrasion with diamond powder alone was found to be enhanced by a few orders of magnitude using a mixed slurry consisting of diamond and metal powders. No strong nucleation enhancement was observed using a metal slurry only for surface treatment. The metal powders used were W, Ta, Mo, Nb, Ti, Al, Fe, Ni, Cu, and Si. It is concluded that the enhanced nucleation is associated with a physico-chemical modification of the substrate surface, attained through a cooperative effect of both the metal and diamond particles during the ultrasonic abrasion process. © 1995 American Institute of Physics.
Prognostic gene signatures for non-small-cell lung cancer (2009)

Resectable non-small-cell lung cancer (NSCLC) patients have poor prognosis, with 30-50% relapsing within 5 years. Current staging criteria do not fully capture the complexity of this disease. Survival could be improved by identification of those early-stage patients who are most likely to benefit from adjuvant therapy. Molecular classification by using mRNA expression profiles has led to multiple, poorly overlapping signatures. We hypothesized that differing statistical methodologies contribute to this lack of overlap. To test this hypothesis, we analyzed our previously published quantitative RT-PCR dataset with a semisupervised method. A 6-gene signature was identified and validated in 4 independent public microarray datasets that represent a range of tumor histologies and stages. This result demonstrated that at least 2 prognostic signatures can be derived from this single dataset. We next estimated the total number of prognostic signatures in this dataset with a 10-million-signature permutation study. Our 6-gene signature was among the top 0.02% of signatures with maximum verifiability, reaffirming its efficacy. Importantly, this analysis identified 1,789 unique signatures, implying that our dataset contains >500,000 verifiable prognostic signatures for NSCLC. This result appears to rationalize the observed lack of overlap among reported NSCLC prognostic signatures.
Formation of Solid Solution of Al<sub>1-x</sub>Si<sub>x</sub>N (0<x≤12%) Ternary Alloy (2001)

When Si was doped into an AlN layer during metalorganic vapor-phase epitaxial growth, the Al density (N Al ) in the AlN layer decreased but the N density (N N ) did not change. The decrease in N Al was almost the same as the Si density (N si ). As N si increased in Si-doped AlN, the lattice constant decreased. These results can be explained by Si atoms replacing Al atoms in Si-doped AlN and subsequent Si–N bond formation. Thus, Si-doped AlN becomes a substitutional solid solution of Al 1- x Si x N ternary alloy. The highest Si density at which the x-ray diffraction peak still appears was 5.8×10 21 cm -3 ( x =12%).
