Magnetic multilayer structures (1990)

This is an overview of work at the IBM Almaden Research Center on magnetic multilayer structures comprising one, several, or many magnetic films sandwiched between nonmagnetic films. In recent years there has been increasing interest in such structures because of their novel and potentially useful properties. Recent examples of magnetic multilayer structures grown by molecular beam epitaxy (MBE) and sputtering are described. It is seen that MBE and sputtering are complementary techniques for the preparation of such structures, and that the ability to modify their magnetic properties by suitably designing their architecture is a key to their further development.
High‐Quality Diesel from Hexose‐ and Pentose‐Derived Biomass Platform Molecules (2011)

Blending in: Lignocellulosic biomass contains hexoses and pentoses, and both of them may be utilized in second-generation biocarburants. A process that uses platform molecules derived from hexoses (5-methylfurfural) and from pentoses (2-methylfuran, or Sylvan) to produce a high quality diesel is presented. The diesel can be blended in any ratio with commercial diesel, and has a high cetane number and good flow properties.
Simulation, Microfabrication, and Control of a Microheater Array (2017)

This paper describes the simulation, fabrication, and feedback control of a microheater array designed for the implementation of real-time control during thermal evolution of microstructure. The ten-channel heating array was designed through finite element simulation and microfabricated to be compatible with in situ imaging in a scanning electron microscope. Control algorithms are implemented that demonstrate cooperative control of the temperature (using calibrated Ti heater line resistances as a proxy) across the set of channels in the array. The goal of this system is to be able to generate controlled thermal, and thus microstructural, and property distribution during processing of polycrystalline materials.
Characteristics of Glucose-6-Phosphate Dehydrogenase form Leuconostoc mesenteroides (1979)

Glucose 6-phosphate dehydrogenase of Leuconostoc mesenteroides which was purifid by an affinity chromatography was studied on the characterization, kinetics and chemical modification. The apparent molecular weight of the enzyme was 112,000 by the gel filtration method of Sephadex G-200 column. The optimum temperature of -linked reation was 50 and the activation energy and the heat of inactivation were 8.36 kcal/mole and -58.2kcal/mole, respectively. The steady state kinetic study showed KG6P, Kemp, and CX KNADP to be 76.9 PM, 7.46 and 7.14 , respectively, and KGGP, KNAD,and aKNm to be 53.7, 115.2 and 702.2 for the -linked reaction at pH 7.8, optimum pH. The pH dependent kinetic constants suggested that the two ionizing groups whose pKa is 7.2 .and pKb is 9.0-9.6 were involved in the enzyme-substrate interaction. Evidence by photooxidation and carboxymethylation of the enzyme suggested that the imidazole group of histidine with pKa group may participate in the catalytic site
A new higher-order method for parameter optimization of time-varying and time-invariant linear dynamic systems (2002)

Dynamic systems are often designed to carry out repetitive tasks. The parameters of the dynamic system influence the optimal trajectory, thereby, affecting the cost of a typical cycle. This brings in the need to select parameters in an optimal way. The conventional method of optimal parameter design, where state equations are augmented to the cost functional using Lagrangean multipliers and the necessary conditions are solved as a 2-point boundary-value problem, is highly computation intensive and is often unreliable to give the solution. In this paper, a new formulation is proposed to solve this problem for a class of time-varying linear dynamic systems. This procedure does not use Lagrangean multipliers, hence, the optimality equations have a completely new form compared to conventional methods. Also, it is shown in the paper that these optimality equations can be solved in a very computationally efficient way to determine the parameter set for optimal design.
A Chromosome-length Assembly of the Black Petaltail ( Tanypteryx hageni ) Dragonfly (2023)

We present a chromosome-length genome assembly and annotation of the Black Petaltail dragonfly (Tanypteryx hageni). This habitat specialist diverged from its sister species over 70 million years ago, and separated from the most closely related Odonata with a reference genome 150 million years ago. Using PacBio HiFi reads and Hi-C data for scaffolding we produce one of the most high-quality Odonata genomes to date. A scaffold N50 of 206.6 Mb and a single copy BUSCO score of 96.2% indicate high contiguity and completeness.
Genetic Studies with S. pombe (2000)

A comprehensive evaluation of GammaTile geometry, dose distribution, and clinical workflow was conducted. Safe intro-operative implantation of GammaTiles requires extensive preplanning and interdisciplinary collaboration. A STaRT workflow was outlined to provide a guideline for an accurate treatment planning and safe implant process at other institutions.
Toward efficient static analysis of finite-precision effects in DSP applications via affine arithmetic modeling (2004)

We introduce a static error analysis technique, based on smart interval methods from affine arithmetic, to help designers translate DSP codes from full-precision floating-point to smaller finite-precision formats. The technique gives results for numerical error estimation comparable to detailed simulation, but achieves speedups of three orders of magnitude by avoiding actual bit-level simulation. We show results for experiments mapping common DSP transform algorithms to implementations using small custom floating point formats.
Rapid and scalable lubrication and replenishment of liquid-infused materials (2016)

Liquid-infused surfaces (LIS) consist of a porous or textured solid matrix infused with a lubricating liquid. The presence of a thin film of the lubricant on the exterior surface facilitates dramatically the shedding of a wide range of liquids and solids, making LIS potential candidates for a variety of applications. However, before LIS can transition into industrial use, durability issues posed by lubricant depletion need to be addressed. In this paper an ‘inside-out-in’ system is introduced for rapid lubrication or relubrication of polymeric LIS. The system consists of an embedded millichannel liquid distribution network connected to the exterior polymer surface using periodically spaced vias and could be used to, for example, lubricate LIS-based personal protective gear. By using periodic contact angle measurements and spray impingement experiments, the authors show that release of a lubricant using this system leads to diminishing contact angle hysteresis of the exterior LIS surface nearly instantaneously. The proposed inside-out-in lubricant dispensing approach is a generic system that provides a rapid and scalable route to refresh the wetting properties of LIS consisting of any polymer–lubricant pair, which could facilitate transition of these materials into industrial use.
Magnetic prospecting at a prehistoric and historic settlement in Maine (2000)

Magnetic surveys at a prehistoric and historic site in Maine were performed in order to improve understanding of cultural features identified from excavations that detailed cultural characteristics at discrete locations, but failed to define the geometry and extent of subsurface features. The objective of the magnetic work was to non-invasively define this spatial distribution of features. Such information is required to nominate both sites to the US National Register of Historic Places. Environmental and cultural factors in Maine favour the application of the magnetic method in archaeological prospecting. At the Spiller Farm palaeoamerican site, excavations had revealed a hearth and over 130 fragments of stone tools. The objective of the magnetic survey was to define additional hearths and cultural material within the vicinity. Measurements were made on a 45 by 25 m grid at 1 m intervals. Signal processing improved definition of a +50 nT anomaly that, upon partial excavation, was found to be associated with a sizeable burnt feature. Laminations in the excavated feature, combined with an increase in palaeo-artefact counts around it, indicate that the feature is a palaeo-hearth, rather than a natural burnt feature. At the Fort Hill historic site, previous excavations revealed a hearth, stone debris related to the fort foundations and numerous historic artefacts but did not resolve the fort geometry. Magnetic measurements were performed on a 55 by 45 m grid at 1 m intervals. Linear anomalies (+20 nT) were interpreted primarily as the response to residual metal in the fort foundations. The geometry of the fort and the meeting house, known to exist from historic accounts, were directly inferred from the survey. The hearth location and artefact distribution correlate well with the magnetic data. The dimensions of the fort (41 by 19 m) were found to be considerably larger than that expected from historic references. Copyright © 2000 John Wiley & Sons, Ltd.
Powder Characteristics and Three-Way Catalytic Activity of Hollow Alumina Made by the Emulsion Combustion Method (2005)

Lanthanum-doped hollow alumina particles (A-E) were made by the emulsion combustion method (ECM). Powder characteristics and three-way catalytic performance were evaluated and compared with those of precipitation-made alumina (A-P). The A-E powder was gamma alumina and 40 m2/g in specific surface area (SSA). The unique hollow structure resulted in a broad peak at 130 nm in the pore size distribution and a large pore volume (3.0 cm3/g) with pore diameters of >20 nm. The A-E powder primarily maintained its shape, crystalline phase and SSA up to 1200°C, indicating high thermal stability. Conversion of total hydrocarbon (THC) started at higher temperatures for the Rh-loaded A-E pellets (Rh/A-E) than for Rh-loaded A-P pellets (Rh/A-P) because of the low dispersion of Rh for Rh/A-E. However, a gradient of the THC conversion-temperature curve was higher for Rh/A-E than for Rh/A-P. The large pore volume can promote good gas accessibility inside the pellets for Rh/A-E, resulting in the high gradient of the THC conversion-temperature curve and thus the high activity at high temperatures where gas diffusion is likely to determine the conversion efficiency. The conversion-temperature curves of CO and NOX showed primarily similar behavior to the THC ones.
Numerical Simulations for Friction Induced Vibrations Considering Temperature-Dependence Effect (2005)

A two-dimensional friction induced vibration model taking the effects of change of material properties due to the temperature rise of a brake-pad into consideration is introduced in order to explain the experimental behavior of a brake pad and rotating disk system. Numerical simulations based on this model are conducted and results such that before the onset of the large amplitude vibrations it takes some minutes after the beginning of the contact was obtained, which is consistent with those of experiments.
Evaluation of expression and function of vascular endothelial growth factor receptor 2, platelet derived growth factor receptors-alpha and -beta, KIT, and RET in canine apocrine gland anal sac adenocarcinoma and thyroid carcinoma (2012)

Known targets of toceranib are expressed in both AGASAC and TC. Given the observed expression of VEGFR and PDGFRα/β and phosphorylation of RET, these RTKs merit investigation as to their roles in the biology of AGSACA and TC and their contribution to toceranib's activity.
Wide band channel characterization for low altitude unmanned aerial system communication using software defined radios (2018)

In the near future, there will be a need for accommodating large populations of fast moving Unmanned Aerial Systems (UAS) operating in uncontrolled, very low level (VLL) (below 500 ft.) airspace. As is well-known, real-time knowledge of the wireless propagation channel is essential for the effective design and optimization of wireless communication systems. In this paper, we propose a software defined radio (SDR) based channel sounder employing a wideband linear frequency modulated continuous wave (FMCW) or chirp waveform technique for low altitude air-to-air (AA) links. This paper discusses both matched filter and heterodyne detector implementations in the receiver, and investigates advantages and disadvantages of both architectures for an SDR implementation in an AA scenario. We also discuss proper windowing techniques in the transmitter to improve sounding resolution. Some proof of concept measurement results using SDRs are presented for a simulated UAS scenario.
A Novel Supramolecular Multicolor Thermometer by Self-Assembly of a π-Extended Zinc Porphyrin Complex (2003)

A zinc complex of (3-pyridyl)porphyrin with an alkynyl sidearm (1) preferentially formed a cyclic tetramer in toluene, which showed supramolecular thermochromism at ambient temperatures of 0-100 degrees C. Because of an appropriate extension of pi-electronic conjugation of the porphyrin chromophore, the thermal-induced self-assembling dynamics of 1 can be detected as a vivid color change from red to yellow to green. In sharp contrast, 2 without any alkynyl group, on heating, developed only a small color change from orange to pink, while 3 bearing two alkynyl groups stayed green and did not display any thermochromism.
Hybrid term indexing for different IR models (2000)

Retrieval effectiveness depends on how terms are extracted and indexed. For Chinese text (and others like Japanese and Korean), there are no space to delimit words. Indexing using hybrid terms (i.e. words and bigrams) were able to achieve the best precision amongst homogenous terms at a lower storage cost than indexing with bigrams. However, this was tested with conjunctive queries. Here, we extended the weighted Boolean models using fuzzy and p-norm measures, as well as the vector space model using the cosine measure, for processing hybrid terms. Our evaluation shows that all IR models using hybrid terms achieve better average precision over those using words. Across different recall values, the weighted Boolean model using fuzzy measures with hybrid terms achieve consistently about 8% higher than those using words. The vector space model using the cosine measures with hybrid terms achieved the best improvement in the average recall and precision.
GIS and Streamflow Analysis to Support E. coli Source Identification (2001)

Bacterial contamination of surface waters is a national concern, with an increasing number ofwaterbodies having detections above health limits for indicator species such as Escherichia coli (E. coli).High concentrations of E. coli have been a major concern in Lake Shafer, a regionally important lake innortheast Indiana, and its tributaries. Watershed assessment and sampling are being conducted in twotributary watersheds of Lake Shafer to determine the major sources of E. coli. Weekly sampling at 21sites, most upstream and downstream of possible sources (livestock areas, forest, septic systems,wastewater treatment plants), is providing temporal and spatial E. coli data. GIS-based analyses wereused in selecting sampling sites and are being used to examine E. coli contribution based on land use.Four continuous stage recorders have been installed at key locations to measure discharge and to aid indetermining relationships between flow and E. coli concentrations. Preliminary results suggest that thereare significantly higher numbers downstream of some potential sources, but interpretation is complicatedby our lack of understanding of bacterial growth in the water under some conditions. Additional data andanalysis will help define E. coli trends in more detail.
Ex Vivo Manipulation of Cell Subsets for Cell Therapies (1996)

Large-scale cell separation and ex vivo expansion technologies will form the basis for development of new cellular products for the treatment of cancer and fatal viral diseases. The cell subsets that are likely to play a significant role in cellular therapy include hematopoietic stem cells, platelet and granulocyte precursors, cytotoxic lymphocytes, and genetically modified hematopoietic or lymphoid precursors. Cell enrichment techniques are required to eliminate tumor cells from autologous stem cell grafts and to reduce the size of culture systems required for expansion or gene transfection. The consumption of expensive culture components such as cytokines and serum may be reduced by the use of perfusion bioreactor devices. Methods that have been developed for the production of cell subsets for cellular therapy are reviewed.
Perimenopausal disorders: Age-related, psychological, and social predictors of their emergence (2012)

Perimenopausal disorders belong to serious problems involving the medico-biological, psychosocial, and socio-cultural aspects of the lives of the women who entered the perimenopausal period (climacterium). A contingent of perimenopausal women surveyed within a biopsychosocial approach was subdivided into the basic group represented by 416 female subjects with climacteric syndrome aged from 42 to 55 years and the control group numbered 138 women with a normal course of their perimenopausal period. Psychosomatic dysfunctions of a multifactorial (biopsychosocial) genesis have been revealed in more than 70% of the women in different age groups with climacteric disorders. Our analysis of the pathogenetical basis underlying the development of their perimenopausal disorders has shown the interdependence of inherited, perinatal, psychological, familial, and societal factors.
Heparin‐binding growth factor isolated from human prostatic extracts (1988)

Prostatic tissue extracts from patients with benign prostatic hyperplasia (BPH) and prostatic carcinoma were fractionated using heparin-Sepharose chromatography. The mitogenic activity of eluted fractions on quiescent subconfluent Swiss Albino 3T3 fibroblasts was tested employing a tritiated-thymidine-incorporation assay. Two peaks of activity were consistently noted--one in the void volume and a second fraction which eluted with 1.3-1.6 M NaCl and contained the majority of the mitogenic activity. Both non-heparin- and heparin-binding fractions increased tritiated incorporation into a mouse osteoblast cell line (MC3T3), while only the heparin-binding fractions stimulated a human umbilical vein endothelial cell line (HUV). No increased uptake of thymidine was seen using a human prostatic carcinoma cell line (PC-3). Sodium dodecyl sulfate/polyacrylamide gel electrophoresis (SDS/PAGE) of lyophilized active fractions showed a persistent band at 17,500 daltons. The purified protein demonstrated angiogenic properties using the chick embryo chorioallantoic membrane (CAM) assay. Western blot analysis using antibodies specific to basic fibroblast growth factor (bFGF) or acidic FGF (aFGF) demonstrated that the former, but not the latter, bound to prostatic growth factor (PrGF), and inhibited its mitogenic activity as well. It appears that PrGF shares homology with basic fibroblast growth factors.
Antibody profiling sensitivity through increased reporter antibody layering (2023)

A method for analyzing a biological sample by antibody profiling for identifying forensic samples or for detecting the presence of an analyte. In an embodiment of the invention, the analyte is a drug, such as marijuana, Cocaine (crystalline tropane alkaloid), methamphetamine, methyltestosterone, or mesterolone. The method comprises attaching antigens to a surface of a solid support in a preselected pattern to form an array wherein locations of the antigens are known; contacting the array with the biological sample such that a portion of antibodies in the sample reacts with and binds to the antigens in the array to form immune complexes; washing away antibodies that do form immune complexes; and detecting the immune complexes, to form an antibody profile. Forensic samples are identified by comparing a sample from an unknown source with a sample from a known source. Further, an assay, such as a test for illegal drug use, can be coupled to a test for identity such that the results of the assay can be positively correlated to the subject&#x27;s identity.
24.4: Distinguished Student Paper : Floating 3D Image for High Resolution Portable Device Using Integral Photography Theory (2015)

In this paper, we achieved the floating 3D image based on integral photography theory to display the image in an oblique viewing angle on portable device. Considering the repeated image overlapping problem in the integral image system, it can be solved by adjusting the receiving angle. In the future, the floating 3D image could integrate with the 3D interactive system to provide more realistic visual experience.
Nanoemulsion formulation for enhancing the aqueous solubility and systemic bioavailability of poorly soluble drugs. (2023)

Nano emulsions are systems for delivering drugs of poor water-solubility with extensive first-pass metabolism and improving their bioavailability. Different techniques develop nano emulsions. Low-energy methods are more effective and do not require expensive equipment, so they should be used instead of high-energy methods. However, high-energy procedures are better for food-substance emulsions as they require a lower surfactant concentration than low-energy approaches. Particularly for low-energy processes, the formulation of nano emulsions involves overlapping techniques.Due to their small particle sizes, nano emulsions are effective in emulsifying active lipophilic compounds and have a variety of uses, which is a promising advantage over conventional emulsions. These systems appear optically clear and have better stability as a result.Also, the diffusion of bioactive substances into the intradermal layers is improved by nano emulsion food component systems, which is crucial in the development of herbal cosmetics.The nano emulsion technology has demonstrated the ability to effectively distribute lipophilic compounds via various administration routes. Nano emulsion systems are beneficial for aesthetic applications due to their transparency, low viscosity, and nano-sized droplets. Antibiotics, anticancer agents, disinfectants, and antiseptics can all be given utilising nano emulsion systems due to their adaptable physiochemical properties, which also enhance the bioactivity of the encapsulated components.
Research for Practice: Programming by Examples (2017)

In every RfP column two experts share a short curated selection of papers on a concentrated, practically oriented topic.
Seeking and sharing health information online (2014)

Search engines and social media are two of the most com-monly used online services; in this paper, we examine how users appropriate these platforms for online health activi-ties via both large-scale log analysis and a survey of 210 people. While users often turn to search engines to learn about serious or highly stigmatic conditions, a surprising amount of sensitive health information is also sought and shared via social media, in our case the public social plat-form Twitter. We contrast what health content people seek via search engines vs. share on social media, as well as why they choose a particular platform for online health activi-ties. We reflect on the implications of our results for design-ing search engines, social media, and social search tools that better support people's health information seeking and sharing needs.
