Lime slurry stabilisation of an expansive soil (2003)

Lime slurry and lime pile techniques are viable choices for in-situ stabilisation of expansive soil deposits. This paper reports the results of a laboratory study on in-situ chemical stabilisation of an expansive soil that permeated lime slurry through an artificially desiccated expansive soil specimen. The soil was desiccated in the laboratory to induce shrinkage cracks in the compacted expansive soil. The shrinkage cracks greatly assisted migration of lime slurry in the expansive soil mass. The efficiency of lime slurry in chemically stabilising the desiccated expansive soil was investigated by comparing the physico-chemical properties and engineering properties of the treated soil with those of the natural soil specimen at two radial distances. Experimental results indicated that migration of lime slurry through the desiccated soil promoted strong lime modification and pozzolanic reactions in the soil mass. The strong soil–lime reactions rendered the soil less plastic, reduced the swell magnitude, and increased the unconfined compressive strength of the lime-slurry-treated specimens. Laboratory results indicate that slurry application to soil deposits with shrinkage is effective, and that it may therefore be preferable to chemically stabilise soil deposits during the dry season.
Self‐oligomerization of NACP, the precursor protein of the non‐amyloid β/A4 protein (Aβ) component of Alzheimer's disease amyloid, observed in the presence of a C‐terminal Aβ fragment (residues 25–35) (1998)

NACP, the precursor protein of the non-amyloid beta/A4 protein (A beta) component of Alzheimer's disease (AD) amyloid, also known as alpha-synuclein, was suggested to seed amyloid plaque formation in AD by stimulating A beta aggregation. We have demonstrated that NACP experienced self-oligomerization only in the presence of a modified A beta fragment (A beta25-35) by using dicyclohexylcarbodiimide. This NACP oligomerization, appearing as a discrete ladder on a Tricine SDS-PAGE, was not observed with other A beta peptides such as the reverse peptide A beta35-25 and A beta1-40, indicating this process was specific not only for the C-terminal peptide sequence of the A beta but also for its orientation. It might be, therefore, suggested that the NACP self-oligomers formed only in the presence of a N-terminally truncated A beta peptide could act as a nucleation center for plaque formation during AD development.
Working group report on advanced high-voltage high-power and energy-storage space systems (1986)

Space systems in the future will probably include high-voltage, high-power energy-storage and -production systems. Two such technologies are high-voltage ac and dc systems and high-power electrodynamic tethers. The working group identified several plasma interaction phenomena that will occur in the operation of these power systems. The working group felt that building an understanding of these critical interaction issues meant that several gaps in our knowledge had to be filled, and that certain aspects of dc power systems have become fairly well understood. Examples of these current collection are in quiescent plasmas and snap over effects. However, high-voltage dc and almost all ac phenomena are, at best, inadequately understood. In addition, there is major uncertainty in the knowledge of coupling between plasmas and large scale current flows in space plasmas. These gaps in the knowledge are addressed.
Self-organizing neuro-fuzzy system for control of unknown plants (2003)

A cluster-based self-organizing neuro-fuzzy system (SO-NFS) is proposed for control of unknown plants. The neuro-fuzzy system can learn its knowledge base from input-output training data. A plant model is not required for training, that is, the plant is unknown to the SO-NFS. Using new data types, the vectors and matrices, a construction theory is developed for the organization process and the inference activities of the cluster-based SO-NFS. With the construction theory, a compact equation for describing the relation between the input base variables and inference results is established. This equation not only gives the inference relation between inputs and outputs but also specifies the linguistic meanings in the process. New pseudo-error learning control is proposed for closed-loop control applications. Using a cluster-based algorithm, the neuro-fuzzy system in its genesis can be generated by the stimulation of input/output training data to have its initial control policy (IF-THEN rules) for application. With the well-known random optimization method, the generated neuro-fuzzy system can learn its data base for specific applications. The proposed approach can be applied on control of unknown plants, and can levitate the curse of dimensionality in traditional fuzzy systems. Two examples are demonstrated.
Advancement in networks for HEP community (2010)

The key role of networks has been brought into focus as a result of the worldwide-distributed computing model adopted by the four LHC experiments, as a necessary response to the unprecedented data volumes and computational needs of the LHC physics program. As we approach LHC startup and the era of LHC physics, the focus has increased as the experiments develop the tools and methods needed to distribute, process, access and cooperatively analyze datasets with aggregate volumes of Petabytes of simulated data even now, rising to many Petabytes of real and simulated data during the first years of LHC operation.
Synthesis of poly(1‐hexene)s end‐functionalized with phenols (2005)

Abstract Electrophilic alkylations of phenol/2,6‐dimethylphenol were performed with vinylidene‐terminated poly(1‐hexene)s using BF 3 ·OEt 2 catalyst. Vinylidene‐terminated poly(1‐hexene)s with M n varying from 400 to 10000 were prepared by bulk polymerization of 1‐hexene at 50 to −20 °C using Cp 2 ZrCl 2 /MAO catalysts. The phenol/2,6‐dimethylphenol‐terminated poly(1‐hexene)s was characterized by NMR ( 1 H, 13 C), UV, IR and vapor phase osmometer (VPO). The isomer distribution ( ortho, para and ortho / para ) was determined by 13 P NMR using a phosphitylating reagent, namely 2‐chloro‐1,3,2‐dioxaphospholane. The number‐average degree of functionality ( F n ) >0.9 with >95% para selectivity could be achieved using low‐molecular‐weight oligomers of poly(1‐hexene)s.

A database of human segmented natural images and its application to evaluating segmentation algorithms and measuring ecological statistics (2002)

This paper presents a database containing 'ground truth' segmentations produced by humans for images of a wide variety of natural scenes. We define an error measure which quantifies the consistency between segmentations of differing granularities and find that different human segmentations of the same image are highly consistent. Use of this dataset is demonstrated in two applications: (1) evaluating the performance of segmentation algorithms and (2) measuring probability distributions associated with Gestalt grouping factors as well as statistics of image region properties.
On the accuracy of PSF representation in image restoration (1993)

Point spread function (PSF) models derived from physical optics provide a more accurate representation of real blurs than simpler models based on geometrical optics. However, the physical PSF models do not always result in a significantly better restoration, due to the coarse sampling of the recording device and insufficiently high signal-to-noise ratio (SNR) levels. Low recording resolutions result in aliasing errors in the PSF and suboptimal restorations. A high-resolution representation of the PSF where aliasing errors are minimized is used to obtain improved restorations. The SNR is the parameter which ultimately limits the restoration quality and determines the need for an accurate PSF model. As a rule of thumb, the geometrical PSF can be used in place of the physical PSF without significant loss in restoration quality when the SNR is less than 30 dB.
A Novel Guided Wave Analogue-To-Digital Converter Using GaAs/AlGaAs Waveguide Technology (1989)

We present results showing error-free operation of a novel 4-bit guided-wave analogue-to-digital converter fabricated in GaAs/GaAlAs for the first time. Experimental and modelling results on high-speed operation of the core modulator device indicate the potential for ADC operation beyond lOGHz.
Solution structure of Phrixotoxin 1, a specific peptide inhibitor of Kv4 potassium channels from the venom of the theraphosid spider <i>Phrixotrichus auratus</i> (2004)

Animal toxins block voltage-dependent potassium channels (Kv) either by occluding the conduction pore (pore blockers) or by modifying the channel gating properties (gating modifiers). Gating modifiers of Kv channels bind to four equivalent extracellular sites near the S3 and S4 segments, close to the voltage sensor. Phrixotoxins are gating modifiers that bind preferentially to the closed state of the channel and fold into the Inhibitory Cystine Knot structural motif. We have solved the solution structure of Phrixotoxin 1, a gating modifier of Kv4 potassium channels. Analysis of the molecular surface and the electrostatic anisotropy of Phrixotoxin 1 and of other toxins acting on voltage-dependent potassium channels allowed us to propose a toxin interacting surface that encompasses both the surface from which the dipole moment emerges and a neighboring hydrophobic surface rich in aromatic residues.

Realisation of magnetic conducting surface usingnovel photonic bandgap structure (1998)

The realisation of a magnetic conducting surface using a novel two-dimensional uniplanar photonic bandgap structure is described. This novel idea is verified by measured results and the results obtained using the finite-difference time-domain method.
Combined Flux Observer With Signal Injection Enhancement for Wide Speed Range Sensorless Direct Torque Control of IPMSM Drives (2008)

This paper proposes a motion-sensorless control system using direct torque control with space vector modulation for interior permanent magnet synchronous motor (IPMSM) drives, for wide speed range operation, including standstill. A novel stator flux observer with variable structure uses a combined voltage-current model with PI compensator for low-speed operations. As speed increases, the observer switches gradually to a PI compensated closed-loop voltage model, which is solely used at high speeds. High-frequency rotating-voltage injection with a single D-module bandpass vector filter and a phase-locked loop state observer with a new synchronization procedure are used to estimate the rotor position, which is needed only by the current model in stator flux observer at low speeds. A new rotor speed estimator for the whole speed-loop range, based on the stator flux speed estimation with a new dynamic correction depending on estimated torque, is proposed and tested. Extensive simulation results and significant experimental results provided good performance for the proposed IPMSM sensorless system in more than 1:1000 speed range, under full-load operation, from very low speeds (1 r/min experimental) up to rated speed.
Effect of purified glutaminase from human ascites fluid on experimental tumor bearing mice. (2001)

Glutamine is the major respiratory fuel and energy source of the rapidly proliferating tumor cells and that is why glutamine clearance by glutaminase therapy provides an opportunity to fight against the neoplasm. Glutaminase from bacterial source was tried on experimental models but had to be excluded because of its limited efficacy. Search for a better glutaminase continued exploiting the mammalian sources. In the present study, glutaminase purified from human ovarian cancer ascites fluid was used in experimental solid and ascites mice model alone and in combination with Cu-Sulphate and heparin. Cumulative findings indicate that the enzyme alone is quite effective in lowering tumor burden and reducing not only the tumor induced angiogenesis, but also an angiogenic inducer, heparin mediated angiogenesis. However, the presence of Cu with the enzyme, amplified the antineoplastic response by improving anti-angiogenic potential and hematological status of the tumor bearing host. Therefore, Cu-glutaminase combination strengthened the hypothesis that together they may provide a better therapeutic regimen in experimental mice tumor model.
A fast linear shape from shading (2003)

A method for computing depth from a single shaded image is presented. Discrete approximations for p and q using finite differences are used, and the reflectance in Z/sub ij/ is linearized. The method is faster, since each operation is purely local. In addition, it gives good results for spherical surfaces, in contrast to other linear methods.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Multiuser Discrete Bit-loading for Digital Subscriber Lines (2007)

This paper proposes an efficient algorithm that produces near-optimal discrete bit-loading for a Gaussian interference channel that models a DSL network. It first takes a continuous bit-loading initialization, and then rounds one user's bits in each tone independently, with rounding direction determined by evaluating a weighted sum rate objective function. After adjusting all the tones of a user, that user's power constraint is met by a power tightening procedure; then, the algorithm moves to the next user. Convergence of the proposed algorithm is proved. This algorithm can be made distributed by only allowing rounding DOWN the bits, and it can be also applied to Gaussian Multiple Access Channel (MAC) and Gaussian Broadcast Channel (BC) with slight modifications.
High-power diode-pumped AlGaAs surface-emitting laser (1999)

We report the development and characterization of an efficient diode-pumped surface-emitting semiconductor laser operating at approximately 870 nm. By using a semiconductor Bragg reflector stack/multiple GaAs quantum well structure, mounted within a conventional laser cavity, we achieved single transverse mode laser output powers of 153 mW. Self-tuning over a 15-nm spectral range has been obtained.
The use of N-hydroxy-5-norbornene-2,3-dicarboximide acitive esters in peptide synthesis. (1974)

N-Hydroxy-5-norbornene-2, 3-dicarboximide (HONB) was found to be an excellent reagent to be used in couple with N, N'-dicyclohexylcarbodiimide (DCC) for the peptide synthesis. Various racemization tests by the use of this reagent were conducted to see the degree of racemization during the peptide synthesis. The newly employed reagent (HONB) decreases racemization, prohibits formation of N-acylurea and affords peptides in excellent yields and a high state of purity. To evaluate this new reagent, luteinizing hormone releasing hormone (LH-RH) was prepared by the new active ester method.
Removal of Heavy Polynuclear Aromatics by Activated Carbons (2018)

Heavy polynuclear aromatics (HPNA) is a complex molecules generated during hydrocracking process in waxy oil. HPNA is eliminated by a commercial activated carbon in the absorber to prevent the fouling in the pipelines and the decrease of product yield. In this work, the commercial activated carbons containing the different micropores and the different mesopores were selected to investigate the influence of pore structure on the HPNA removal. Here, the surface area of commercial activated carbons were quite equivalent. The results show that the activated carbon possessing the high mesopores can adsorb HPNA better than the activated carbon having the high micropores in spite of the summation of a micropore volume and a mesopore volume are quite equal. Therefore, the mesopore structure is a major role in the HPNA removal.

Synthesis, molecular modeling, DNA binding, and antitumor properties of some substituted amidoanthraquinones (1988)

A series of 1- and 1,4-substituted amidoanthraquinones have been prepared, with side chains possessing basic nitrogen atoms. Computer modeling and energy calculations have shown that all eight compounds can bind intercalatively to DNA and that there are significant differences in the additional nonbonded and electrostatic interactions possible at the DNA binding site. Solution DNA binding and closed-circular DNA unwinding studies confirmed intercalative interactions, and the predicted differences in strength of interactions between mono- and disubstituted compounds were found. All compounds were modestly cytotoxic to L1210 cells in culture. In vivo activity against L1210 and S180 tumors was not found for the monosubstituted compounds, whereas the four disubstituted ones had varying levels of measurable, though low, activity.
Oral and Intravenous Acetylcysteine for Treatment of Acetaminophen Toxicity: A Systematic Review and Meta-analysis (2013)

Studies report similar rates of hepatotoxicity for oral and IV acetylcysteine, but direct comparisons are lacking. While it is difficult to disentangle the effects of dose and duration from route, our findings suggest that the rates of hepatotoxicity are similar for oral and IV administration.
Secure distributed computation of anonymized views of shared databases (2012)

We consider the problem of computing efficient anonymizations of partitioned databases. Given a database that is partitioned between several sites, either horizontally or vertically, we devise secure distributed algorithms that allow the different sites to obtain a k -anonymized and ℓ-diverse view of the union of their databases, without disclosing sensitive information. Our algorithms are based on the sequential algorithm [Goldberger and Tassa 2010] that offers anonymizations with utility that is significantly better than other anonymization algorithms, and in particular those that were implemented so far in the distributed setting. Our algorithms can apply to different generalization techniques and utility measures and to any number of sites. While previous distributed algorithms depend on costly cryptographic primitives, the cryptographic assumptions of our solution are surprisingly minimal.
Self-Organized Porous Titanium Oxide Prepared in H[sub 2]SO[sub 4]/HF Electrolytes (2003)

The formation of porous on titanium was investigated in electrolytes containing low concentrations of HF (0.05-0.4 wt %). Under optimized electrolyte conditions and extended polarization, highly ordered porous is obtained that consists of pore arrays with single pore diameter of 140 nm and a pore spacing of 150 nm. During the formation process, significant current oscillations are observed with an amplitude which depends strongly on the HF content of the electrolyte. Electrochemical, scanning electron microscope and X-ray photoelectron spectroscopy investigations show that the porous layer forms under a competition of formation and oxide dissolution up to a limiting thickness of and that the time scale for complete self-ordering for the investigated systems is in the order of several hours. © 2003 The Electrochemical Society.

GENERALIZED XANTHOMATOSIS WITH CALCIFIED ADRENALS (1956)

THIS REPORT deals with a case of generalized xanthomatosis which exhibited an unusual feature—massive calcification of the adrenals. Massive bilateral calcification of the adrenal glands in early infancy is a very rare finding, and very few cases have been reported in which this lesion has been discovered on the plain x-ray picture in vivo. REPORT OF CASE A 2-month-old girl was admitted to the pediatric department of the Hadassah University Hospital on March 12, 1954, from another hospital, with the diagnosis of suspected acute abdomen. The infant had been healthy and had gained weight satisfactorily on breast feeding until a week before admission, when she started to vomit, although not forcefully. On admission the infant appeared very ill and had a pale yellowish complexion, but no abnormal pigmentation of the skin was noted. The breathing was superficial. The abdomen was distended, and no peristaltic waves were heard. The liver was
The toxicity of cadmium and resulting hazards for human health (2006)

Cadmium (Cd) has been in industrial use for a long period of time. Its serious toxicity moved into scientific focus during the middle of the last century. In this review, we discuss historic and recent developments of toxicological and epidemiological questions, including exposition sources, resorption pathways and organ damage processes.
How coping mediates the effect of optimism on distress: A study of women with early stage breast cancer. (1993)

At diagnosis, 59 breast cancer patients reported on their overall optimism about life; 1 day presurgery, 10 days postsurgery, and at 3-, 6-, and 12-month follow-ups, they reported their recent coping responses and distress levels. Optimism related inversely to distress at each point, even controlling for prior distress. Acceptance, positive reframing, and use of religion were the most common coping reactions; denial and behavioral disengagement were the least common reactions. Acceptance and the use of humor prospectively predicted lower distress; denial and disengagement predicted more distress. Path analyses suggested that several coping reactions played mediating roles in the effect of optimism on distress. Discussion centers on the role of various coping reactions in the process of adjustment, the mechanisms by which dispositional optimism versus pessimism appears to operate, third variable issues, and applied implications.
A new class of general-base matrices and a formalism for optimal parallel/pipelined computer architecture (2002)

A new class of general-base matrices and a novel matrix formalism which provides mathematical tools for the search for and the attainment of optimal parallel/pipelined computer architecture are presented. "Sampling matrices", "span matrices" and "p/sup k/-optimal" matrices are shown to bridge the gap between algorithmic description and computer architecture. Optimal memory partitioning, addressing elimination and a minimization of shuffle operations are obtained using the proposed formalism. The approach is illustrated using algorithms of generalized spectral analysis which are more complex and general than the usually factored Fourier transform. New general-base factorizations for three different forms of the Chrestenson transform are obtained. A class of optimal parallel and parallel-pipelined general-base processors for the implementation of the Chrestenson transform are presented.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Multi-label visual classification with label exclusive context (2011)

We introduce in this paper a novel approach to multi-label image classification which incorporates a new type of context - label exclusive context - with linear representation and classification. Given a set of exclusive label groups that describe the negative relationship among class labels, our method, namely LELR for Label Exclusive Linear Representation, enforces repulsive assignment of the labels from each group to a query image. The problem can be formulated as an exclusive Lasso (eLasso) model with group overlaps and affine transformation. Since existing eLasso solvers are not directly applicable to solving such an variant of eLasso in our setting, we propose a Nesterov's smoothing approximation algorithm for efficient optimization. Extensive comparing experiments on the challenging real-world visual classification benchmarks demonstrate the effectiveness of incorporating label exclusive context into visual classification.
