Repointing mortar joints in historic masonry buildings (1998)

The purpose of this brief is to provide general guidance on appropriate materials and methods for repointing historic masonry buildings and it is intended to benefit building owners, architects, and contractors. The brief should serve as a guide to prepare specifications for repointing historic masonry. It should also help develop sensitivity to the particular needs of historic masonry, and to assist historic building owners in working cooperatively with architects, architectural conservators and historic preservation consultants, and contractors.
Generic ASIC architecture for digital signal processing (2003)

The architectural methodology behind a novel high-level VLSI cell compiler currently under development is described. The tool is aimed specifically at digital signal processing applications, synthesizing powerful arithmetic kernel processors from high-level parameterized schematics. Underlying the tool is a generic pipelined numerical processing architecture, flexible enough in its use of innate parallelism to meet a wide range of throughput requirements with minimal waste of resources. Machines are synthesized using this architecture as a blueprint. To this end, the tool encapsulates the essential knowledge required to assemble a useful set of arithmetic operators over all local and global parametric combinations. Some multiplier instances are illustrated.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Neural associative memory storing gray-coded gray-scale images (2003)

We present a neural associative memory storing gray-scale images. The proposed approach is based on a suitable decomposition of the gray-scale image into gray-coded binary images, stored in brain-state-in-a-box-type binary neural networks. Both learning and recall can be implemented by parallel computation, with time saving. The learning algorithm, used to store the binary images, guarantees asymptotic stability of the stored patterns, low computational cost, and control of the weights precision. Some design examples and computer simulations are presented to show the effectiveness of the proposed method.
Triple Negative Breast Carcinomas (2009)

The cDNA microarrays allows the classification of breast cancers into 6 groups: luminal A, luminal B, luminal C, normal breast-like, human epidermal growth factor receptor 2-positive, and basal-like. This latter is characterized by the expression of basal cytokeratins (CKs), and frequent negativity for hormone receptors and human epidermal growth factor receptor 2. There is a marked parallelism between triple negative breast carcinomas and basal-like carcinoma, but these are not equivalent terms. Estimated concordance is around 80%. CK5 seems to be the best marker for the identification of these tumors. Other good markers to identify these tumors are CK14, CK17, and epidermal growth factor receptor. A subset of triple negative breast carcinomas has myoepithelial differentiation, with positivities for smooth muscle actin, p63, S-100, and CD10 among others. Recent studies suggest that basal like carcinomas are originated from mammary stem cells.
Enhancement of the polycation‐mediated DNA uptake and cell transfection with Pluronic P85 block copolymer (1996)

Polyelectrolyte complexes formed between DNA and poly(N-ethyl4-vinylpyridinium) cations were shown to effectively transfect mammalian cells [7]. This work suggests that the polycation-mediated uptake of the plasmid DNA and cell transfection are significantly enhanced when these complexes are administered simultaneously with a poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) copolymer, Pluronic P85. The uptake studies were performed using radioactively labeled pRSV CAT plasmid on NIH 3T3, MDCK, and Jurkat cell lines. The transfection was investigated by chloramphenicol acetyltransferase assay using 3T3 cells as a model. The effects reported may be useful for the enhancement of the polycation-mediated cell transfection.
New tunable coplanar microwave phase shifter with nematic crystal liquid (2008)

The liquid crystals known for their applications as viewers have interesting features for a microwave circuit design's so-called "agile frequency". These circuits offer the advantage to change their frequency response according to an external command. Here we present a new phase shifter agile frequency liquid crystal substrate. Indeed the nature of viscous liquid crystal requires development ad-hoc structures.The measurements are characterised in [26-40] GHz band. This phase shifter with agile frequency will be integrated into an antenna network and will be used to control the radiation pattern of the synthesised array antenna.
STRING-MAN: a new wire robot for gait rehabilitation (2004)

This paper presents a novel robotic prototype for advanced gait rehabilitation. This system integrates sophisticated robotic technology with control algorithms. The robot opens up new possibilities for the field of rehabilitation for restoring posture balancing and gait motoric functions. The paper provides an overview of the system's fundamental components, such as mechanical structure, patient-machine interface, sensory systems, control algorithms, etc. The results of some initial experiments also are included.
Transmit and receive filter design for OFDM based WLAN systems (2010)

We analyze the effect of different pulse shaping filters on the orthogonal frequency division multiplexing (OFDM) based wireless local area network (LAN) systems in this paper. In particular, the performances of the square root raised cosine (RRC) pulses with different rolloff factors are evaluated and compared. This work provides some guidances on how to choose RRC pulses in practical WLAN systems, e.g., the selection of rolloff factor, truncation length, oversampling rate, quantization levels, etc.
On multi-feature integration for deformable boundary finding (2002)

Precise segmentation of underlying objects in an image is very important especially for biomedical image analysis. We present an integrated approach for boundary finding using region and curvature information along with the gradient. Unlike the previous methods, where smoothing is enforced by penalizing curvature, here the grey level curvature is used as an extra source of information. However, information fusion may not be useful unless used properly. To address that, we present results that highlight the pros and cons of using the various sources of information and indicate when one should get precedence over the others.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
<title>Improvements to mask inspectability by use of pattern proximity correction</title> (2000)

Inspection is one of the major challenges in mask making, as it is one of its most performance crucial steps in the entire mask making process. Especially contact patterns show difficulties in die-to-database inspection as the CAD data asks for square corners. The paper presents the impact of Laser Proximity Correction (LPC) on the inspectability of contact and line patterns. LPC is a mask enhancement technique improving image quality and CD linearity for laser pattern generators. The use of the linewidth bias monitor tool in order to characterize CD uniformity over the entire plate is demonstrated.

Point-spread function optimization in isoSTED nanoscopy (2015)

IsoSTED nanoscopy, a variant of stimulated emission depletion (STED) microscopy, utilizes two opposing objective lenses and features the highest three-dimensional resolution of STED nanoscopes currently available. However, this technique is limited by axially repetitive side minima in the interference pattern of the depletion point-spread function (PSF), which can lead to ghost images. Here, we describe novel strategies to further improve the performance of isoSTED nanoscopy by reshaping the PSF. In particular, we propose employing moderate defocus on the depletion beam to reduce the side minima. Furthermore, we demonstrate a simplified alternative based on objective misalignment and quantitatively compare the expected performance between the two approaches.
Proteins of the accessory sex glands associated with the oocyte‐penetrating capacity of cauda epididymal sperm from holstein bulls of documented fertility (2006)

We previously reported that accessory sex gland fluid (AGF) from high fertility (HF) bulls influenced the oocyte-penetrating capacity of cauda epididymal sperm from low fertility (LF) bulls, based on in vitro fertilization (IVF) assays. The present study determined if AGF proteins were associated with these effects. Nineteen IVF assays with 12 bulls were grouped as follows. Group I (n = 8): assays where sperm from LF bulls exposed to AGF from HF bulls had greater oocyte penetration than exposed to homologous AGF. Group II (n = 7): sperm from LF bulls to AGF from HF bulls versus homologous AGF showed no significant differences. Group III (n = 4): sperm from LF bulls treated with homologous AGF had greater fertility than sperm treated with AGF from HF bulls. Sire fertility was based on nonreturn rates (NNR) and AGF collected by artificial vagina from bulls with cannulated vasa deferentia. Two-dimensional SDS-PAGE maps of AGF were analyzed by PDQuest and proteins identified by tandem mass spectrometry and Western blots. Differences in spot intensity between AGF of HF and LF bulls were compared across groups of IVF assays (P < 0.05). The expression of BSP A1/A2 and A3, BSP 30 kDa, clusterin, albumin, phospholipase A(2) (PLA(2)), and osteopontin was greater in the AGF of HF bulls in Group I as compared to Groups II and III. Conversely, there was less nucleobindin in the AGF of HF bulls in Group I than in Groups II and III. This is the first report of nucleobindin (58 kDa/pI 5.6) in male reproductive fluids, using both immunoblots and mass spectrometry. Thus, the effect of AGF from HF bulls on epididymal sperm is likely the result of specific proteins expressed in the AGF.
Image warps for artistic perspective manipulation (2010)

Painters and illustrators commonly sketch vanishing points and lines to guide the construction of perspective images. We present a tool that gives users the ability to manipulate perspective in photographs using image space controls similar to those used by artists. Our approach computes a 2D warp guided by constraints based on projective geometry. A user annotates an image by marking a number of image space constraints including planar regions of the scene, straight lines, and associated vanishing points. The user can then use the lines, vanishing points, and other point constraints as handles to control the warp. Our system optimizes the warp such that straight lines remain straight, planar regions transform according to a homography, and the entire mapping is as shape-preserving as possible. While the result of this warp is not necessarily an accurate perspective projection of the scene, it is often visually plausible. We demonstrate how this approach can be used to produce a variety of effects, such as changing the perspective composition of a scene, exploring artistic perspectives not realizable with a camera, and matching perspectives of objects from different images so that they appear consistent for compositing.
Generation of Higher Number of Voltage Levels by Stacking Inverters of Lower Multilevel Structures With Low Voltage Devices for Drives (2016)

This paper proposes a new method of generating higher number of levels in the voltage waveform by stacking multilevel converters with lower voltage space vector structures. An important feature of this stacked structure is the use of low voltage devices while attaining higher number of levels. This will find extensive applications in electric vehicles since direct battery drive is possible. The voltages of all the capacitors in the structure can be controlled within a switching cycle using the switching state redundancies (pole voltage redundancies). This helps in reducing the capacitor size. Also, the capacitor voltages can be balanced irrespective of modulation index and load power factor. To verify the concept experimentally, a nine-level inverter is developed by stacking two five-level inverters and an induction motor is run using V/f control scheme. Both steady state and transient results are presented.
Self-assembling peptide-based nanoparticles enhance anticancer effect of ellipticine in vitro and in vivo (2012)

The anticancer activity observed in this study coupled with minimal side effects encourages further development of peptide-mediated delivery of anticancer drugs, ellipticine in the present case, for clinical application.
Correction of anisoplanatic phase errors in digital holography (2008)

The quality of coherent images computed from digital holography or heterodyne array data is sensitive to phase errors of the reference and/or object beams. A number of algorithms exist for correcting phase errors in or very near the hologram plane. In the case of phase errors introduced a nonnegligible distance away from hologram plane, the resulting imagery exhibits anisoplanatism. A feature of coherent imaging is that such phase errors may be corrected by simply propagating the aberrated fields (from the object) from the hologram plane to the plane where the phase errors were introduced and applying the phase-error correction algorithms to the fields in that plane. We present experimental results that demonstrate correction of such anisoplanatic phase errors.
Three-dimensional ISAR imaging of maneuvering targets using three receivers (2001)

The conventional ISAR image is a two-dimensional (2-D) projection of a three-dimensional (3-D) object surface. The image (projection) plane is related to the motion of a target with respect to the line of radar sight (LOS). In general, the image plane and the image scale in the cross range direction can not be determined by the traditional ISAR system with one receiver unless the target motion knowledge is known. In this paper, we propose a new ISAR system with three receivers. Using the three-receiver ISAR system, 3-D images of maneuvering targets can be generated, where the knowledge of the target motion is not required.

Active integrated circuit synthesis (1968)

Active Integrated Circuit Synthesis presents the latest practical results of research conducted in university and industrial laboratories as well as the new theories now emerging. The coherent and comprehensive treatment starts with basic discussions of prime elements of integrated components and generating elements of basic gain blocks. The book progresses through state- variable theory, active and passive RC synthesis (including feedback circuits), element replacement, method comparison, and advanced topics as distributed networks and quasilossless time-variable synthesis.

Utilization of Existing Wells in Seismograph Work (1931)

The writers describe a method of utilizing a well in a seismic exploration of the surrounding area for deep domes, with particular reference to a supposed dome near the well which, for any reason, may have missed its objective. Most of the paper is devoted to methods of utilizing a well near the flank of a salt dome for the purpose of making a seismic profile deep down the flanks. These methods are especially adapted to determining the extent of mushrooming such as that existing at Barbers Hill and the Allen dome.

Increased adherence of sickled and phosphatidylserine-enriched human erythrocytes to cultured human peripheral blood monocytes. (1985)

The precise mechanism by which sickle erythrocytes (RBC) are removed from the circulation is controversial, although it is possible that enhanced recognition of these cells by circulating mononuclear phagocytes could contribute to this process. We investigated this possibility by interacting sickle cells with cultured human peripheral blood monocytes. Our results show that both irreversibly sickled cells (ISC) and deoxygenated reversibly sickled cells (RSC) had a higher avidity for adherence to monocytes than did oxygenated sickle and normal RBC. ISC were the most adherent cell type. Adherence of RSC to monocytes was found to be reversible; reoxygenation of deoxygenated RSC resulted in a significant decrease in RSC--monocyte adherence. Concomitant with alterations in sickle RBC adherence were alterations in the organization and bilayer distribution of membrane phospholipids in these cells. Specifically, enhanced adherence was associated with increased exposure of RBC membrane outer leaflet phosphatidylserine (PS) and phosphatidylethanolamine, whereas lack of adherence was associated with normal patterns of membrane phospholipid distribution. To investigate the possibility of whether the exposure of PS in the outer membrane leaflet of these cells might be responsible for their recognition by monocytes, the membranes of normal RBC were enriched with the fluorescent PS analogue 1-acyl-2[(N-4-nitro-benzo-2-oxa-1,3-diazole)aminocaproyl]-phosphatidy lse rine (NBD-PS) via transfer of the exogenous lipid from a population of donor phospholipid vesicles (liposomes). RBC enriched with NBD-PS exhibited enhanced adherence to monocytes, whereas adherence of RBC enriched with similar amounts of NBD-phosphatidylcholine (NBD-PC) was not increased. Furthermore, preincubation of monocytes with PS liposomes resulted in a approximately 60% inhibition of ISC adherence to monocytes, whereas no inhibition occurred when monocytes were preincubated with PC liposomes. These findings strongly suggest that erythrocyte surface PS may be a ligand recognized by receptors on human peripheral blood monocytes and that abnormal exposure of PS in the outer leaflet of the RBC membrane, as found in sickle RBC, might serve to trigger their recognition by circulating monocytes. Our results further suggest that abnormalities in the organization of erythrocyte membrane phospholipids may have significant pathophysiologic implications, possibly including shortened cell survival.
Production of auxotrophic mutants in ferns (1969)

A method has been devised for the selection of auxotrophic mutants in higher plants. The method depends upon the incorporation of BUdR into the DNA of non-auxotrophic cells and upon its lack of incorporation into the DNA of auxotrophic cells. A wide range of auxotrophic types were recovered.

We have studied the mechanical behavior of Zr40Ti14Ni10Cu12Be24 through uniaxial compression and nanoindentation experiments. Quantitative measurements of the serrated plastic flow observed during uniaxial compression are reported. These data are used to predict temperature increases in single shear bands due to local adiabatic heating caused by the work done on the sample as shear propagates progressively across the sample. Since the predicted temperature increases are insufficient to reach the glass transition temperature, it is unlikely that localized heating is the primary cause of flow localization. Instead, localization of shear is more likely caused by changes in viscosity associated with increased free volume in the shear bands. The orientation of the shear bands in compression tests and an indentation size effect for the onset of plastic flow in nanoindentation both point to increased free volume as the cause of localization.

Night blindness precipitated by isotretinoin in the setting of hypovitaminosis A (1999)

A 16-year-old male developed night blindness 2 weeks after starting isotretinoin at a dose of 20 mg per day for cystic acne. He also had cystic fibrosis, complicated by hepatic cirrhosis. Despite long-term oral vitamin A supplementation, serum vitamin A levels were found to be 0.3 mumol/L (normal range 0.9-2.5 mumol/L). Oral vitamin A replacement was instituted with resolution of his visual symptoms in 6 months. Isotretinoin therapy was successfully continued with no deterioration in liver function. Isotretinoin has been reported to cause deterioration in night vision. In vitro evidence suggests isotretinoin may interfere with the processing of endogenous vitamin A in the retina. This case highlights the need for careful monitoring of serum vitamin A status in patients with malabsorptive states on isotretinoin therapy.
A New High-Resolution Trinitron Color Picture Tube for Display Application (1980)

Recent progress in high-speed electronic computers capable of processing a great number of input data calls for the development of a high-resolution color display device. Among the proposed display devices, the cathode ray tube continues to offer many advantages and promises to be the dominant device for the foreseeable future. The resolution and picture quality of the cathode ray system, however, must be improved for this new application.
Noise, crosstalk and distortion in mixed analog/digital integrated circuits (2003)

In mixed analog/digital circuits, op-amp noise, aliased noise, crosstalk from digital circuits, and distortion limit the dynamic range available. Op-amp design, gain partitioning and layout are the key in achieving >25-dB signal-to-noise ratios in an analog path containing 25 op amps. The authors present methods used to maximize dynamic range and measured results obtained from ASIC (application-specific integrated-circuit) devices.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
