Estimation of the moisture absorption rate of glass fiber reinforced plastic using electromagnetic induction testing (2022)

We present a novel estimation method for the moisture absorption rate (MAR) of glass fiber reinforced plastics (GFRPs) using electromagnetic induction testing (EIT). The relationship between the permittivity and MAR were analytically calculated using a simple moisture absorption model. Moreover, we experimentally obtained the magnitude of the displacement current for dielectric specimens with known permittivity values. The equations were derived from the magnitude of the displacement current measured during EIT by combining the analytical and experimental results. To verify the validity of the proposed method using the derived equations, we applied EIT to GFRPs with different MARs. It was found that MAR can be qualitatively evaluated using the proposed method.

A novel stop codon mutation within the hepatitis B surface gene is detected in the liver but not in the peripheral blood mononuclear cells of HIV‐infected individuals with occult HBV infection (2012)

To characterize occult HBV infection (OHB) in different compartments of HIV+ individuals. This retrospective study involved 38 consecutive HIV+ patients; 24 HBsAg negative (HBV-) and 14 HBsAg positive (HBV+). OHB was assessed in serum samples, liver tissue (LT) and peripheral blood mononuclear cells (PBMC) by genomic amplification of the partial S, X and precore/core regions. HBV genomic analysis was inferred by direct sequencing of PCR products. The intracellular HBV-DNA was measured by a quantitative real-time PCR. HBV+ patients were used as a control for HBV replication and genomic profile. In HBV- patients, HBV-DNA was undetectable in all serum samples, while it was found positive in 7/24 (29%) LT in which genotype D prevailed (57%). HBV-DNA was found in 6/7 (86%) PBMC of occult-positive and none of occult-negative LT. Significantly lower HBV-DNA load was present in both compartments in OHB+ with respect to the HBV+ group (LT: P = 0.002; PBMC: P = 0.026). In the occult-positive cases, HBV replication was significantly higher in LT than in PBMC (P = 0.028). A hyper-mutated S gene in PBMC and a nucleotide mutation at position C695 in LT that produces a translational stop codon at amino acid 181 of the HBs gene characterized OHB. In this group of HIV+ persons, OHB is frequent and exhibits lower replication levels than chronic HBV in the different compartments examined. HBV-DNA detection in PBMC may offer a useful tool to identify OHB in serum-negative cases. The novel HBs gene stop codon found in LT could be responsible for reduced production leading to undetectability of HBsAg.
Dependence of electron spin relaxation times on the crystal orientation of CdTe grown on (100)ZnSe/GaAs substrates (2010)

Abstract Depending on the shutter sequence used to initiate CdTe deposition, either (100) or (111) CdTe layers can be reproducibly grown on (100) ZnSe/GaAs substrates. Using a hexagonal surface model for (111) CdTe we propose a mechanism for the crystalline orientation selectivity. We use time‐resolved Kerr rotation to monitor the electron spin dynamics in these films. While the spin lifetime is found to depend on material quality, only (100) films show a clear temperature dependence, a peculiar feature we believe to arise from different residual strains in the layers with the two different orientations.

Comparison of putative cooperative mechanisms in cardiac muscle: length dependence and dynamic responses (1999)

Length-dependent steady-state and dynamic responses of five models of isometric force generation in cardiac myofilaments were compared with similar experimental data from the literature. The models were constructed by assuming different subsets of three putative cooperative mechanisms. Cooperative mechanism 1 holds that cross-bridge binding increases the affinity of troponin for Ca2+. In the models, cooperative mechanism 1 can produce steep force-Ca2+ (F-Ca) relations, but apparent cooperativity is highest at midlevel Ca2+ concentrations. During twitches, cooperative mechanism 1 has the effect of increasing latency to peak as the magnitude of force increases, an effect not seen experimentally. Cooperative mechanism 2 holds that the binding of a cross bridge increases the rate of formation of neighboring cross bridges and that multiple cross bridges can maintain activation of the thin filament in the absence of Ca2+. Only cooperative mechanism 2 can produce sarcomere length (SL)-dependent prolongation of twitches, but this mechanism has little effect on steady-state F-Ca relations. Cooperativity mechanism 3 is designed to simulate end-to-end interactions between adjacent troponin and tropomyosin. This mechanism can produce steep F-Ca relations with appropriate SL-dependent changes in Ca2+ sensitivity. With the assumption that tropomyosin shifting is faster than cross-bridge cycling, cooperative mechanism 3 produces twitches where latency to peak is independent of the magnitude of force, as seen experimentally.
Micro- and nanofluidic technologies for epigenetic profiling (2013)

This short review provides an overview of the impact micro- and nanotechnologies can make in studying epigenetic structures. The importance of mapping histone modifications on chromatin prompts us to highlight the complexities and challenges associated with histone mapping, as compared to DNA sequencing. First, the histone code comprised over 30 variations, compared to 4 nucleotides for DNA. Second, whereas DNA can be amplified using polymerase chain reaction, chromatin cannot be amplified, creating challenges in obtaining sufficient material for analysis. Third, while every person has only a single genome, there exist multiple epigenomes in cells of different types and origins. Finally, we summarize existing technologies for performing these types of analyses. Although there are still relatively few examples of micro- and nanofluidic technologies for chromatin analysis, the unique advantages of using such technologies to address inherent challenges in epigenetic studies, such as limited sample material, complex readouts, and the need for high-content screens, make this an area of significant growth and opportunity.
Lasers and the reactor ignition problem. (1972)

Some published estimates of the laser energy (W0) required to heat an inertially confined D–T target in a pulsed fusion reactor are summarized. Assuming a thermal efficiency of 1/3 and a laser heating efficiency (target energy/laser pumping energy) of 100%, most of these estimates of W0 range between 10 and 1000 MJ, depending on the various assumptions which are made about the degree of solid-state target compression, the possibility of target tamping, and the required reactor power gain. Any energy gain due to fusion reactions in material other than the target is omitted in these calculations. These estimates of W0 are then compared with the maximum fusion outputs which can be handled with and without damage to the structure and the low permissible cost of replacing damaged components is stressed. The possibility of using nonlinear absorption of repetitively pulsed CO2 lasers to start up a steady-state stellarator which is fueled by D–T pellet injection and has an output of ~10 GW(E) is then discussed. It is shown that laser energies as low as 80 kJ may be feasible and possible advantages and difficulties of such a hybrid inertial/magnetic confinement approach are outlined.
rFSA: An R Package for Finding Best Subsets and Interactions (2019)

Herein we present the R package rFSA, which implements an algorithm for improved variable selection. The algorithm searches a data space for models of a user-specified form that are statistically optimal under a measure of model quality. Many iterations afford a set of <i>feasible solutions</i> (or candidate models) that the researcher can evaluate for relevance to his or her questions of interest. The algorithm can be used to formulate new or to improve upon existing models in bioinformatics, health care, and myriad other fields in which the volume of available data has outstripped researchers' practical and computational ability to explore larger subsets or higher-order interaction terms. The package accommodates linear and generalized linear models, as well as a variety of criterion functions such as Allen's PRESS and AIC. New modeling strategies and criterion functions can be adapted easily to work with <b>rFSA</b>.
West Nile Virus Infection in Mosquitoes, Birds, Horses, and Humans, Staten Island, New York, 2000 (2001)

West Nile (WN) virus transmission in the United States during 2000 was most intense on Staten Island, New York, where 10 neurologic illnesses among humans and 2 among horses occurred. WN virus was isolated from Aedes vexans, Culex pipiens, Cx. salinarius, Ochlerotatus triseriatus, and Psorophora ferox, and WN viral RNA was detected in Anopheles punctipennis. An elevated weekly minimum infection rate (MIR) for Cx. pipiens and increased dead bird density were present for 2 weeks before the first human illness occurred. Increasing mosquito MIRs and dead bird densities in an area may be indicators of an increasing risk for human infections. A transmission model is proposed involving Cx. pipiens and Cx. restuans as the primary enzootic and epizootic vectors among birds, Cx. salinarius as the primary bridge vector for humans, and Aedes/Ochlerotatus spp. as bridge vectors for equine infection.

A direct method based on hydride exchange for determining the redox potentials of 1,4-dihydropyridines related structurally to nicotine adenine dinucleotide (NADH) (1982)

The relative two-electron redox potentials of N-substituted 1,4-dihydropyridines related to NADH can be determined by a direct method in which the equilibrium composition of a 1,4-dihydropyridine–pyridinium salt mixture is determined by 1H n.m.r. spectroscopy.
Domino inspired MOBILE networks (2012)

MOBILE networks can be operated in a gate-level pipelined fashion allowing high through-output. If MOBILE gates are directly chained, a four-phase clock scheme is required. A single phase scheme has been recently reported that alternates rising and falling edge-triggered MOBILE gates. A novel two-phase interconnection scheme resembling conventional domino pipelines is proposed and validated. It exhibits advantages in terms of speed with respect to both four-phase and single-phase interconnection schemes. In addition, the new architecture improves logic flexibility regarding the domino pipeline counterpart, since inverting and non-inverting stages can be interspersed.
Transcranial Surgery for Pituitary Adenomas (2005)

Although the transsphenoidal approach is the preferred approach to the vast majority of pituitary tumors with or without suprasellar extension, the transcranial approach remains a vital part of the neurosurgical armamentarium for 1 to 4% of these tumors. The transcranial approach is effective when resection becomes necessary for a portion of a pituitary macroadenoma that is judged to be inaccessible from the transsphenoidal route because of isolation by a narrow waist at the diaphragma sellae, containment within the cavernous sinus lateral to the carotid artery, projection anteriorly onto the planum sphenoidale, or projection laterally into the middle fossa. The application of a transcranial approach in these circumstances may still be mitigated by response to prolactin inhibition of prolactinomas, the frequent lack of necessity to remove asymptomatic nonsecretory adenomas from the cavernous sinus, and the lack of evidence that sustained chemical cures can be reliably achieved by removal of secretory adenomas (adrenocorticotropic hormone, growth hormone) from the cavernous sinus. Cranial base surgical techniques have refined the surgical approach to pituitary adenomas but have had less effect on actual surgical indications than anticipated. Because application of the transcranial approach to pituitary adenomas is and should be rare in clinical practice, it is useful to standardize the technique to a default mode with which the surgical team is most experienced and, therefore, most comfortable. Our default mode for transcranial pituitary surgery is the frontotemporal-orbitozygomatic approach.
A novel low-complexity deterministic algorithm for DS-CDMA signature sequence generation (2006)

This paper presents a novel low-complexity deter- ministic technique for the generation of DS-CDMA signature sequences with a wide range of correlation properties that is based on the well-known Viterbi search algorithm. This approach provides a fast method of generating binary or polyphase codes with no inherent constraints on code length or size of the codeset. In addition, the algorithm is iterative and provides increasingly better codes in terms of average mean-square aperiodic cor- relation properties as the number of iterations increases. We build on the results in (1) and develop a much-lower-complexity version of the algorithm that could allow for some level of signature-sequence adaptation in a near-real-time environment. The algorithm is shown to outperform existing complex-code design techniques and provides codes with similar correlation properties to well-known codesets while using significantly fewer unique phases.
A Phase 3, Multicenter, Open Label, Randomized Study Of Abarelix Versus Leuprolide Plus Daily Antiandrogen In Men With Prostate Cancer (2002)

Abarelix as monotherapy achieves medical castration significantly more rapidly than combination therapy and avoids the testosterone surge characteristic of agonist therapy. Both treatments were equally effective in reducing serum prostate specific antigen, and achieving and maintaining castrate levels of testosterone.
Hemoperfusion-Hemodialysis Ineffective for Paraquat Removal in Life-Threatening Poisoning? (1985)

We report on a patient treated with hemoperfusion-hemodialysis (HP-HD) for severe paraquat poisoning. This procedure was adopted since the combination of adsorption and dialysis may improve overall drug removal. On admission blood paraquat was 15.8 micrograms/ml. He received conventional treatment and combined HP-HD which started within 3 hours after ingestion of the chemical and lasted 5 hours. Blood samples were obtained during and after HP-HD. The samples during HP-HD were taken before the charcoal column, between the charcoal column and the artificial kidney and after the artificial kidney. Blood clearances of paraquat were 116 +/- 32 ml/min (n=6) for the charcoal column (HP), 90 +/- 54 ml/min (n=6) for the artificial kidney (HD) and 151 +/- 37 ml/min (n=6) for the combined systems (HP-HD). After HP-HD a limited rebound of blood paraquat level was seen. One day after admission renal and hepatic failure had developed, and the patient died after 5 days. Tissue paraquat levels (microgram/g wet tissue) were: skeletal muscle 9.4, pancreas 6.0, prostate 5.6, thyroid 4.2, lungs 4.0, bone marrow 4.0, kidney 3.1, spleen 2.9, adrenal 2.9, heart 2.8, liver 2.3, stomach and testis below 1.0. Measurements of blood levels demonstrated the efficient clearances of paraquat with HP-HD from the central (plasma) compartment. However, the present results confirmed those previously reported which suggest that the efficiency of short HP-HD in treating severe paraquat poisoning is questionable since paraquat levels in the peripheral (tissue) compartment remain elevated.
Xavier Moreno Juliá, La División Azul. Sangre española en Rusia, 1941-1945 (2010)

La recherche universitaire sur la contribution de l’Espagne à l’effort de guerre hitlérien est restée balbutiante jusqu’à ces dernières annés dans l’historiographie espagnole. Dans le cas particulier de l’intervention militaire sur le front russe, plus d’un demi-siècle d’une vision franquiste a légué une image littéraire de la Division bleue liée à la mystique des anciens combattants. Ce lourd héritage se faisait encore sentir dans les années 1980 et 1990, dans certaines œuvres qu’on pourrait...
Performance Indicators in Business Value-Creating Organizations (2012)

In this paper I propose a general model to understand (not merely describe) the operating logic of Busi-ness Value-Creating Organizations and, in particular of the capitalistic firm - that is, the business for-profit organization.When viewed as autopoietic and teleologic organizations, firms can be interpreted as operating systems for efficient transformation that carry out five parallel transformations,a. a productive transformation of factors into production; this is a transformation of utility, gov-erned by productivity and by quality;b. an economic transformation of costs and revenues into operating income; this is a transforma-tion of value, governed by prices and therefore by the market; c. a financial transformation of risks, which transforms capital into returns and guarantees the maintenance of its financial integrity;d. an entrepreneurial transformation of information into strategies, which leads to a continual re-adjustment of the firm's strategic position;e. a managerial (organizational) transformation of strategies into actions of management control.The model allows us to propose a system of performance indices and measures and to highlight the mu-tual relationships among these indices and measures.
SOME ADVANCES IN NONWOVEN STRUCTURES FOR ABSORBENCY, COMFORT AND AESTHETICS (2002)

Abstract Modern disposable articles for personal and health care should offer excellent absorbency as well as comfort in use, need to be aesthetic and ensure discretion. There are numerous challenges facing the designers of nonwoven fabrics for absorption of body fluids, which result from various engineering contradictions. Combining all necessary functions, i.e. fluid acquisition, distribution and retention, in one uniform, simple composite made of fibers and superabsorbent polymer particles may be problematic. One can easily predict from theory that improving one parameter will result in a deterioration of another function. High-performance, multifunctional unitary structures require separation of functional components and their placement in a nonwoven web in a predetermined, oriented fashion. Some examples of such structures are proposed here and the experimental test results are discussed to demonstrate the advantages of the studied materials. The aesthetics of the finished article as well as the comfort of their use depend mainly on the bulk and mechanical properties of the absorbent core, such as integrity, softness and pliability. The paper provides some examples of engineered nonwoven webs having these desired attributes.
Disturbance Field Characteristics of a Transversely Excited Burner (2011)

Transverse acoustic instabilities in premixed, swirl-stabilized flames are an important problem in low NOx combustors. Transverse excitation of swirling flames involves complex interactions between acoustic waves and fluid mechanic instabilities. This paper presents high-speed PIV characterization of the flow field characteristics of a swirling, annular jet under reacting and nonreacting conditions. These data show that the flame response to transverse acoustic excitation is a superposition of acoustic and vortical disturbances that fluctuate in both the longitudinal and transverse direction. In the nozzle near-field region, the disturbance field is a complex superposition of short wavelength and convecting vortical disturbances, as well as longer wavelength transverse and longitudinal acoustic disturbances. Very near the nozzle, distinct vortical structures are evident that are associated with the separating inner and outer annulus shear layers. Their relative phasing on the left and right side of the burner annulus changes by 180° under conditions where the burner centerline is nominally at a transverse acoustic velocity node and antinode. These suggest that the dominant excited instability mode of the annular jet changes from axisymmetric to helical as the structure of the acoustic mode shape changes. Farther downstream, these structures disappear rapidly and the disturbance field is dominated by the longer wavelength, transverse acoustic field.
