A model for hysteretic magnetic properties under the application of noncoaxial stress and field (1993)

Although descriptions of the effect of stress on spontaneous magnetization within a single domain already exist, there remains no adequate mathematical model for the effects of noncoaxial magnetic field and stress on bulk magnetization in a multidomained specimen. This article addresses the problem and provides a phenomenological theory that applies to the case of bulk isotropic materials. The magnetomechanical hysteresis model of Sablik and Jiles is thus extended to treat magnetic properties in the case of noncoaxial stress and magnetic field in an isotropic, polycrystalline medium. In the modeling, noncollinearity between magnetization and magnetic field is taken into account. The effect of roll-axis anisotropy is also considered. Both magnetic and magnetostrictive hysteresis are describable by the extended model. Emphasis in this article is on describing properties like coercivity, remanence, hysteresis loss, maximum flux density, and maximum differential permeability as a function of stress for various angular orientations between field and stress axis. The model predictions are compared with experimental results.
Raman spectroscopic analysis of whole blood acetylcholinesterase (2014)

Raman spectra were taken from whole sheep’s blood with varying levels of acetylcholinesterase (AChE) inhibition using 229 and 532 nm laser excitation wavelengths. AChE levels were inhibited using the organophosphates malathion, paraoxon-ethyl, and octamethyldiphosphoramide and confirmed using the Ellman method. This AChE activity level was investigated with the Raman spectra and analyzed using a partial least squares calibration and cross validation to determine if the AChE activity could be predicted from the Raman spectrum. Correlation scores of 0.78 and 0.26 between the measured and predicted AChE activity were observed using 229 and 532 nm excitation, respectively. A estimate limit of detection was found to be approximately 0.01 ΔA/min.
Beryllium Sensitization, Chronic Beryllium Disease, and Exposures at a Beryllium Mining and Extraction Facility (2001)

In this study, we examine beryllium sensitization, chronic beryllium disease (CBD), and workplace exposures at a beryllium mining (mine) and extraction facility (mill) in Delta, Utah. Historical airborne beryllium data collected between 1970-1999 included general area (GA), breathing zone (BZ), and personal lapel (LP) measurements and calculations of job-specific quarterly daily-weighted averages (DWVAs). We compared GA, BZ, and DWA data to airborne beryllium data from a mixed beryllium products facility and a beryllium ceramics facility located in Elmore, Ohio and Tucson, Arizona, respectively. At the Delta facility, jobs involving beryllium hydrolysis and wet-grinding activities had the highest air concentrations; annual median GA concentrations were less than 0.3 microg/m3 or both areas. Annual median GA sample concentrations ranged from 0.1-0.4 microg/m(-3) at Delta. These levels were generally lower than Elmore (0.1-1.0 microg/m3) and were comparable to the Tucson facility (0.1-0.4 microg/m3). Median BZ concentrations were higher, whereas DWAs were lower at the Delta facility than at the other two facilities. Among the 87 employees at the Delta facility, 75 participated in the medical survey; there were three persons sensitized, one with CBD. The individual with CBD previously worked at the Elmore facility for 10 years. Cumulative CBD incidence rates were significantly lower at the Delta facility: 0.3 percent compared to 2.0 percent for Elmore and 2.5 percent for the Tucson facility. Sensitization and CBD prevalence rates determined from cross-sectional surveys for the Delta facility were lower than but not significantly different from rates at the other two facilities. There was no sensitization or CBD among those who worked only at the mine where the only exposure to beryllium results from working with bertrandite ore. Although these results are derived from a small sample, this study suggests that the form of beryllium may affect the likelihood of developing CBD. Specifically, exposure to beryl and bertrandite ore dusts or to beryllium salts, in the absence of exposure to beryllium oxide particulates appears to pose a lower risk for developing CBD.
Influence of Gluconic Acid on Enzyme Inactivation and Color Retention in Canned Apricots and Peaches (1988)

ABSTRACT Apricots, clingstone and freestone peaches packed in tin‐free steel cans with up to 1.1% gluconic acid in the syrup retained better color than fruits packed without the acidulant. Up to 0.44% by weight gluconic acid did not affect heat resistance of peroxidase/polyphenol‐oxidase enzyme systems in apricots. Requirements for heat inactivation of enzymes increased with fruit maturity, from F 100°c = 1.3 min with z = 16°C in canning ripe, to F 100°C = 7 min with z = 61.5°C in soft ripe apricots. Enzyme regeneration occurred within 48 hr. Methods tested for measuring enzyme activity arc discussed.
Identification of a Locus Involved in Systemic Dissemination of Yersinia enterocolitica (2001)

A putative LysR-type transcriptional activator, Hre20, was identified previously in an in vivo expression technology screen designed to identify factors which are expressed early during infection by Yersinia enterocolitica (G. M. Young and V. L. Miller, Mol. Microbiol. 25:319-328, 1997). An insertion in hre20, now designated rscR, resulted in increased splenic dissemination of bacteria during infection in a BALB/c mouse model. A nonpolar mutation was generated in rscR, and examination of this strain in the BALB/c mouse model demonstrated that the mutation in rscR was responsible for the increased dissemination to the spleen that was seen in the original experiments. RscR is homologous to the LysR family of transcriptional regulators; thus, a screen was undertaken to identify genes regulated by RscR. A strain containing an insertion in the chromosomal rscR gene and carrying rscR on a plasmid under the control of the inducible araBAD promoter was mutagenized with an mTn5Km-2 transposon containing a promoterless lacZY. Eighteen insertions were identified which appeared to respond to levels of RscR, and these were classified into four allelic groups based on Southern blot hybridization analysis. Representative members were sequenced from three allelic groups. Sequencing revealed insertions in an ORF with no known homologues, a homologue of OmpF of Serratia marcescens, and a locus (designated rscBAC) with similarity to the hmwABC locus of Haemophilus influenzae. The hmwABC locus promotes adherence of H. influenzae to host cells (S. J. Barenkamp and J. W. St. Geme III, Infect. Immun. 62:3320-3328, 1994; J. W. St. Geme III, S. Falkow, and S. J. Barenkamp, Proc. Natl. Acad. Sci. USA 90:2875-2879, 1993). A strain containing a deletion mutant of rscA, the hmwA homologue, exhibits increased splenic dissemination of bacteria during infection in a BALB/c mouse model, similar to the rscR mutant. This suggests that the phenotype of an rscR mutant is due to the loss of RscA.

Postconcussive Symptoms in Children with Mild Closed Head Injuries (1999)

Postinjury increases in PCS occur in a sizable minority of children with mild CHI and more often than among uninjured siblings. Increases in PCS following mild CHI are associated with premorbid neurological and psychosocial vulnerability, but also with postinjury decrements in neuropsychological and neurobehavioral functioning.
ОЦЕНКА ГЕНЕТИЧЕСКОЙ И ФЕНОТИПИЧЕСКОЙ СТАБИЛЬНОСТИ ЖИВОЙ ГРИППОЗНОЙ ВАКЦИНЫ ПРОТИВ ПОТЕНЦИАЛЬНО ПАНДЕМИЧЕСКОГО ВИРУСА ГРИППА ПТИЦ (2014)

В настоящей работе представлены результаты изучения генетической стабильности клинических изолятов, полученных в двойном слепом рандомизированном плацебо-контролируемом клиническом исследовании от взрослых здоровых волонтеров, привитых живой гриппозной вакциной (ЖГВ) против потенциально пандемического вируса гриппа птиц сероподтипа Н5. Н5–ЖГВ кандидат был подготовлен в развивающихся куриных эмбрионах (РКЭ) методом классической реассортации вируса гриппа Н5 с донором аттенуации А/Ленинград/134/17/57 (H2N2) и обладал необходимыми для ЖГВ cвойствами температурочувствительности и холодоадаптированности (ts/ca фенотип). Выделение вакцинного вируса осуществляли путем культивирования носовых смывов от волонтеров в РКЭ. Изучение ts/ca фенотипа изолятов проводили в РКЭ, инкубированных при 33, 26 и 40 °C. Секвенирование производилось с помощью автоматического секвенатора 3130xl (Applied Biosystems). Все изоляты были получены в первый день после вакцинации и сохранили ts/ca фенотипические характеристики и полный набор аттенуирующих мутаций, характерный для донора аттенуации. Спонтанные мутации, появившиеся в гемагглютинине в процессе производства вакцины и ее репликации в верхних дыхательных путях волонтеров, не повлияли на фенотипические свойства изолятов. Таким образом, результаты клинического исследования продемонстрировали фенотипическую и генетическую стабильность потенциально пандемической H5–ЖГВ.
High salt intake in pregnancy alters maturation of glomeruli in the rat offspring (2012)

There is currently discussion on the optimal salt intake and uncertainty whether both high and low salt intake is associated with adverse effects. One aspect has so far not be considered, i.e. the potential impact of salt intake during pregnancy on kidney function and blood pressure in the offspring. Faulty fetal programming, amongst others by high or low salt intake, leads to alterations in kidney morphology and albuminuria in the offspring. A low number of glomeruli is known to cause high blood pressure later in life. It was the purpose of the present study to clarify whether very high (or low) salt intakes in pregnancy affect kidney development in the offspring. Sprague-Dawley rats were fed normal (0.15%), medium (1.3%), or high (8.0%) salt diet during pregnancy and weaning. The number of glomeruli (mature, immature, and S-shape bodies) was assessed at 1 week postnatally. The expression of proteins of interest was assessed (by western blotting) at 1 week postnatally and at term. There was no difference between the groups with respect to litter size, birth weight, and placenta size. At age 1 week the number of S-shaped bodies was significantly lower (405±308) and the number of mature glomeruli (818±405) and layers of developing glomeruli (7.1±0.6) was significantly higher in the offspring of mothers on high-salt compared to the medium or low salt groups (1044±490, 460±304, and 5.9±0.9 respectively). As a net result the total number of glomeruli was significantly lower in the offspring of mothers on high-salt (9476±1264) compared to the medium or low salt groups (11175±1920). At 1 week of age in the offspring of mothers on high salt the glomeruli were bigger compared to lower salt intake. The expression of Pax-2 (54±23% vs. 100±28%) and FGF-2 (72±33% vs. 100±30%) was significantly lower in the offspring of mothers on high-salt consistent with their causative role. We conclude that high maternal salt intake during pregnancy accelerates maturation of glomeruli in the offspring, but reduces the final number of glomeruli.
Relationship Between Degradation of PML-RAR and Differentiation (1999)

To The Editor:

In a recent issue of Blood, Fanelli et al[1][1] reported that constitutive degradation of PML-RARα through the proteasome pathway mediates retinoic acid (RA)-resistance in a derivative cell line of NB4 (NB4.007/6). The context of this study contradicts our hypothesis that the
Long-range transport of magnetic microbeads using simple planar coils placed in a uniform magnetostatic field (2003)

We propose an approach for magnetic microbead transport in microfluidic channels over long-range distances using an array of simple planar coils. The latter are placed in a uniform static magnetic field, the role of which is to impose a permanent magnetic moment to the microbeads. The very small magnetic field gradient of a simple planar coil is then sufficient to displace the microbeads. The long-range displacement is assured by arranging adjacent coils in the array with spatial overlap in a three-phase actuation scheme.

Sense-and-respond supply chain using model-driven techniques (2007)

The results of an effort to build a sense-and-respond solution for a supply chain by using a model-driven development framework are described in this paper. One of the components of the framework is the IBM Research-developed model-driven business-transformation (MDBT) toolkit, a set of formal models, methods, and tools. The inventory optimization analytics used to improve supply chain performance are also described. This approach is illustrated through a case study involving the IBM System x™ supply chain.
Multi-protocol embedded PCS IP in a FPGA-SOC (2006)

Several strategies that were employed for developing next-generation embedded Hard IP are reviewed. Mixed signal Hard IP developed for a multi-protocol serial interface physical layer at 0.622Gbps to 3.125Gbps was redeployed for 0.622Gbps to 6.375Gbps data rates. Ensuring quality meant adopting a strongly modular approach to design and verification. The configuration space of the Hard IP had to be bounded intelligently. Major architectural enhancements were necessary instead of a simple performance upgrade of the previous Hard IP. Verification complexity mandated design and verification re-use. Emulation and vendor soft IF interoperability testing was another strategy employed for first silicon success
E‐selectin‐mediated rolling facilitates pancreatic cancer cell adhesion to hyaluronic acid (2017)

Tumor cell extravasation is a multistep process preceded by cell rolling and arrest on the vessel wall <i>via</i> the formation of specific receptor-ligand bonds. The strength, availability, and number of receptor-ligand bonds regulate the rate by which tumor cells tether, roll, and adhere to vascular walls. Although the mechanics of selectin-mediated rolling have been extensively studied, little is known regarding how tumor cell rolling on selectins facilitates adhesion to a distinct substrate-bound protein with different kinetic properties. By using multicomponent protein patterning and a microfluidic system, we evaluated how E-selectin-dependent rolling modulates hyaluronic acid (HA) adhesion as a function of fluid shear, contact time, and the spacing between E-selectin and HA regions patterned on the substrate. We show that tumor cells rolling on E-selectin were ∼40-fold more likely to bind to HA than nonrolling cells in shear flow. Furthermore, E-selectin-dependent rolling promotes adhesion to HA by both physically slowing cells and enabling them to position proximal to the surface, thereby increasing the on rate of adhesion. A better understanding of tumor cell adhesion under physiologic shear would lead to the development of new diagnostic assays and pave the way to clinical approaches aimed ultimately to halt metastasis.-Shea, D. J., Li, Y. W., Stebe, K. J., Konstantopoulos, K. E-selectin-mediated rolling facilitates pancreatic cancer cell adhesion to hyaluronic acid.
TITANATE-BASED CERAMIC AS A MATRIX FOR CURIUM AND RARE EARTH ELEMENT FRACTION OF RADIOACTIVE WASTE IMMOBILIZATION (2020)

The effective isolation of radioactive waste (RW) from the environment is the main problem for the further development of nuclear power. The main phases in titanate-based ceramics are perovskite, rutile, zirconolite and murataite. Murataite grains have a zonal structure with high content of rare earth elements at the center of structure and low content of these at edges, that precludes their leaching in contact with a solution. Murataite-based ceramics containing simulated rare earth elements of high level waste (HLW) were produced via melting of oxide mixtures in a resistance furnace at 1500C. All samples were composed of mainly murataite and minor perovskite, crichtonite, zirconolite, and pyrophanite/ilmenite phases. Thus, murataite is the dominant host phase for a sample containing zirconium oxide. All samples were analyzed by scanning electron microscopy with an energy dispersive X-ray spectroscopy. Elemental leaching rates from the ceramic with low perovskite content were lower by one order of magnitude then leaching rates for high perovskite content.
Speed Control of Brushless DC Motor: A Review (2015)

. (10) Abstract: This paper gives the review of the Brushless DC motor and the speed control method for it. Brushless DC Motor (BLDC) is one of the best electrical drives that have increasing popularity due to their high efficiency, reliability, good dynamic response, and very low maintenance. Due to these advantages, the BLDC motors are recently used in Automobile, HVAC, CNC-machines and domestic appliance. It is electronically commuted motor. The operation of the BLDC motor control is based on the rotor position sensing method. For the rotor position sensing used mainly two strategy, sensor and sensor less scheme. This paper gives idea about various sensing methods, control for BLDC motors and recent research trend in BLDC motor.
Quantitative and Qualitative Standards for Islet Isolation Assessment in Humans and Large Mammals (1991)

Several procedures have been recently developed to separate and purify pancreatic islets from large mammals, including humans. It is often difficult to interpret and compare results, mainly because of lack of standardization of criteria for Islet Isolation Assessment (IIA). In small animals, such as rodents, it is generally not a problem to identify and count all the islet tissue retrieved, due to the small numbers with which we are dealing in these species. In larger mammals, several hundred thousand islets can be obtained from a single pancreas, making it critical to correctly sample, identify, count, and verify insulin-producing tissue. The purpose of this workshop was to discuss and determine minimal, simple requirements for IIA, not to indicate absolute parameters for islet count, purity, or function. Both quantitative and qualitative criteria for IIA have been discussed, the main topics being determination of islet number, islet volume, purity of final preparations, documentation of morphologic integrity, viability tests, in vitro function studies (static incubation and perifusion), and in vivo function studies after transplantation in diabetic athymic rodents.
Maneuver-Aware Pooling for Vehicle Trajectory Prediction (2021)

Autonomous vehicles should be able to predict the future states of its environment and respond appropriately. Specifically, predicting the behavior of surrounding human drivers is vital for such platforms to share the same road with humans. Behavior of each of the surrounding vehicles is governed by the motion of its neighbor vehicles. This paper focuses on predicting the behavior of the surrounding vehicles of an autonomous vehicle on highways. We are motivated by improving the prediction accuracy when a surrounding vehicle performs lane change and highway merging maneuvers. We propose a novel pooling strategy to capture the inter-dependencies between the neighbor vehicles. Depending solely on Euclidean trajectory representation, the existing pooling strategies do not model the context information of the maneuvers intended by a surrounding vehicle. In contrast, our pooling mechanism employs polar trajectory representation, vehicles orientation and radial velocity. This results in an implicitly maneuver-aware pooling operation. We incorporated the proposed pooling mechanism into a generative encoder-decoder model, and evaluated our method on the public NGSIM dataset. The results of maneuver-based trajectory predictions demonstrate the effectiveness of the proposed method compared with the state-of-the-art approaches. Our "Pooling Toolbox" code is available at https://github.com/m-hasan-n/pooling.
PHASED ARRAY FEEDS FOR LOW NOISE REFLECTOR ANTENNAS (1996)

Phased array feeds offer the possibility of more efficient use of large radio astronomy reflector antennas by providing more closely spaced beams over a wide field of view and higher aperture efficiency in each beam than have been realized with horn feeds. Phased arrays have been used extensively in rapid scanning radars and shaped-beam satellite systems, but the array design criteria for low-noise radio astronomy antennas are markedly different, particularly as they affect array sampling density. Element spacing in the focal plane must be less than lA for large FID reflectors and less than about 0.7A for FID < 0.5. This rules out conventional horns as array elements and imposes a limit on the array bandwidth. The receive-only case of radio astronomy permit the use of a number of signal combining techniques that do not degrade system sensitivity. Problems of array weight optimization, mutual coupling, and correction of reflector errors are examined briefly in this paper.
Significance of Bruch's membrane in the creation of iatrogenic chorioretinal venous anastomosis (1994)

Iatrogenic retinal to choroidal vein anastomoses, as a method of bypassing retinal venous occlusions has been reported in dogs in which Bruch's membrane is poorly formed. In order to determine whether chorioretinal venous anastomoses can be induced in an animal with a Bruch's membrane that is well developed as in humans, pigmented rats were chosen. A high intensity, small spot size argon green laser beam of 514 nm was used to induce the anastomosis. Three out of 5 rat eyes developed a retinal vein to choroidal vein anastomosis. The success rate of iatrogenic retinal to choroidal vein anastomoses in the rat was comparable to that obtained in the dog. This study suggests that Bruch's membrane was not significant in the creation of an iatrogenic chorioretinal venous anastomosis.
Within-category discrimination of musical chords: Perceptual magnet or anchor? (1994)

Recent speech research has demonstrated that the presence of prototypes may be reflected in the internal structure of speech categories. Some speech results have found lower discrimination in a vowel P context compared to a NP context, suggesting that a prototype may function as a perceptual magnet, effectively decreasing perceptual distance, and thus, discriminability, between stimuli. The current study examines the function of prototypes in a musical category; another natural, but nonspeech, category. Prototype (P) and nonprototype (NP) sets of major triad stimuli were constructed, with stimuli in the P set being more representative of the category than the NP stimuli. Musically experienced subjects rated the stimuli in each set for goodness as a major triad, with the highest rated stimulus serving as a prototype standard for a subsequent discrimination task. Results from the discrimination task demonstrated better performance in the prototype context. The current nonspeech results appear to follow predictions based on classification and perceptual models (to be discussed), and provide a natural, nonspeech contrast to speech findings. The results will also be addressed in terms of music perception, including aspects such as different temperment systems and the differential importance of chord components.
