Skin Penetration of Terpenes from Essential Oils and Topical Vehicles (2006)

The purpose of this study was to evaluate the in vitro cutaneous penetration of five terpenes--linalool, linalyl acetate, terpinen-4-ol, citronellol and alpha-pinene--applied in pure essential oils or in dermatological formulations (o/w emulsion, oily solution or hydrogel) containing 0.75 % w/w of the essential oils. Different skin absorption was observed depending on the type of the vehicle and terpenes' log P values. Cutaneous accumulation of terpenes is several times higher when they are applied in pure essential oils than in topical vehicles. Penetration of terpinen-4-ol to the skin was better from an oily solution (approximately 90 microg/cm (2)) than from an emulsion (60 microg/cm (2)). No penetration of linalyl acetate from topical vehicles into viable skin was observed, but also for this terpene penetration to the upper layers of the stratum corneum was 2-times higher when an oily solution was used. In contrast, the cutaneous absorption of linalool was the same from both vehicles (50-60 microg/cm (2)). The skin penetration of alpha-pinene was not traceable when it was applied in an oily solution. Only a small amount (approximately 5 microg/cm (2)) of this terpene was determined in viable skin after application as a hydrogel. Citronellol applied in a hydrogel penetrated into all skin layers in a total amount of 25 microg/cm (2), while no penetration into viable skin layers after application of an oily solution was noted. Only citronellol permeated into the acceptor medium.
The effects of randomizing values of interaural disparities on binaural detection and on discrimination of interaural correlation (1997)

The purpose of this study was to assess whether randomizing (roving) baseline interaural parameters of binaural stimuli would adversely affect performance in masking-level differences and in interaural correlation-discrimination paradigms. Listeners' detection thresholds were measured in NoSo and NoS pi configurations for both broadband (100-3000 Hz) and narrow-band (450-550 Hz) maskers centered at 500 Hz. In addition, thresholds of interaural decorrelation (from a reference correlation of 1.0) were measured for 100-Hz-wide bands of noise centered at 500 Hz. Data were obtained under conditions in which either values of ITD or values of IID were roved both within and across trials. Data were also collected in the absence of a rove. The range of the rove was +/- 500 microseconds for ITDs and was +/- 6 dB for IIDs. The duration of the stimuli was varied between 17 and 310 ms. Overall, the results indicate that, independent of duration, roving the interaural cues produced small degradations of performance as compared to data obtained in the absence of a rove. The data are inconsistent with the notion that binaural detection depends upon reliable changes in laterality produced by adding S pi signals to diotic maskers. On the other hand, the data are consistent with modern models of binaural processing.
Controlled co-crystallization of zeolites A and X (2002)

Zeolites A and X were co-crystallized in controlled ratios from one synthesis gel. With increasing potassium content of the synthesis gel or increasing proportion of Na-Y seeds in a mixture of Na-Y and Na-A seeds, the ratio of zeolite X to zeolite A in the synthesis product increased.
A formal foundation for workflow composition, workflow view definition, and workflow normalization based on petri nets (2005)

In retail information systems it is common practice to subsume the data of products into product groups, which o#ers organizational advantages for example when new branches are opened, because they are assigned product groups instead of single products. Inspired by this approach, this paper focuses on business processes and proposes the usage of workflow modules stored in a workflow warehouse, which represent reusable, standardized components that are used to build more complex workflow models. In particular, the paper provides a formal foundation for such compositions in form of a workflow algebra based on Petri nets, which has similar operators known from relational algebra in databases. In addition, the need for a concept of workflow normalization is presented, which arises during the composition of workflow modules. Finally, it is shown how the algebra can also be applied in the context of Web service composition.
Cycle-by-cycle average input current sensing method for LLC resonant topologies (2013)

Average input current is an important control parameter for many power supply control techniques, but it is difficult to obtain in LLC resonant topologies due to the irregular current waveform and the existence of circulation current. Conventional current sensing methods have low bandwidth and are inaccurate. This paper proposes a cycle-by-cycle average input current sensing method. It utilizes the series resonant capacitor to derive the average input current, thus is lossless, accurate, and low-cost. The proposed method can be extended to other topologies that include a series capacitor. Thus it is potentially advantageous in vast applications.
Syncytium Formation in Cultured Human Lymphoid Tissue: Fusion of Implanted HIV Glycoprotein 120/41-Expressing Cells with Native CD4 <sup>+</sup> Cells (1995)

While glycoprotein gp120/41 clearly causes HIV-infected cells to form syncytia in monolayers and in suspension, there is unfortunately scant knowledge on syncytium formation in tissues. We implanted gp120/41-expressing cells labeled with fluorescent particles inside blocks of human lymphoid tissue kept in long-term histoculture. Observed by confocal microscopy, together with immunohistochemical and morphological analysis of implanted cells, more than one-third of these gp120/41-expressing cells fused with native CD4+ cells of the host tissue, yielding small (three to five nuclei) syncytia. Such widespread fusion of gp120/41-expressing cells in tissue in vitro, together with the finding of increased virulence of syncytium-inducing isolates of HIV, support the hypothesis that syncytium formation within lymph tissue of HIV-infected individuals contributes to AIDS pathogenesis. This system and the methods developed may provide a way to study HIV-infected cells inside the very tissue whose destruction may prevent immune system repopulation.
A Model-Driven Approach to Generate Schemas for Object-Document Mappers (2019)

Many actual NoSQL systems are schemaless, that is, the structure of the data is not defined beforehand in any schema, but it is implicit in the data itself. This characteristic is very convenient when the data structure suffers frequent changes. However, the agility and flexibility achieved is at the cost of losing some important benefits, such as 1) assuring that the data stored and retrieved fits the database schema; 2) some database utilities require to know the schema, and; 3) schema visualization helps developers to write better code. In previous work, we proposed a model-based reverse engineering approach to infer schema models from NoSQL data. Model-driven engineering (MDE) techniques can be used to take advantage of extracted models with different purposes, such as schema visualization or automatic code generation. Here, in this paper, we present an MDE solution to automate the usage of Object-NoSQL mappers when the database already exists. We will focus on mappers that are available for document systems (Object-Document mappers, ODMs), but the proposed approach is mapper-independent. These mappers are emerging to provide similar functionality to Object-Relational mappers: they are in charge of the mapping of objects into NoSQL data (documents in the case of ODMs) for object-oriented applications. We show how schemas and other artifacts (e.g. validators and indexes) for ODMs can be automatically generated from inferred schemas. The solution consists of a two-step model transformation chain, where an intermediate model is generated to ease the code generation. We have applied our approach for two popular ODMs: Mongoose and Morphia and validated it with the StackOverflow dataset.
Packetizing voice for mobile radio (1994)

In present mobile radio systems, conventional FM techniques are used to transmit speech in its analog form. A number of digital schemes have been proposed in the past as an alternative. To overcome the effects of Rayleigh fades that appear in the received speech as noise bursts in the form of "pops" and "clicks", the author proposes packetizing speech and encoding the packets in an error-detecting code before transmitting them. If the receiver detects an error, it throws away the packet and requests the transmitter to retransmit the same packet. If the requested packet has not arrived in a given time period, the missed packets are replaced with zero amplitude values. The variable delays that packets are subjected to as a result of this procedure are smoothed out before packets are played back so that they all appear contiguous at the receiving end. The resulting improvement in the SNR at the receiving end depends, among other things, on the maximum delay and the vehicle speed, and is achieved in addition to any improvement that is possible with a specially designed coder. For example, with 4 ms long packets and 12 ms of delay, the SNR improves by about 13 dB at a vehicle speed of 35 mph and 17 dB at 12 mph.< <ETX xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">></ETX>
Transendocardial Autologous Bone Marrow Mononuclear Cell Injection in Ischemic Heart Failure (2005)

Eleven months after treatment, morphological and immunocytochemical analysis of the sites of ABMM cell injection showed no abnormal cell growth or tissue lesions and suggested that an active process of angiogenesis was present in both the fibrotic cicatricial tissue and the adjacent cardiac muscle. Some of the pericytes had acquired the morphology of cardiomyocytes, suggesting long-term sequential regeneration of the cardiac vascular tree and muscle.
High‐frequency ultrasound measurement of dermis and subcutaneous fat in the newborn infant (1995)

High-frequency ultrasound measurement of skin and subcutaneous fat thickness is precise and reliable for in vivo assessment of body fat in newborn infants. Further validation of the technique relative to neonatal skin and nutritional state is, however, needed before the ultrasound technique can be used as routine in neonatalogical monitoring.
A relA/spoT Homologous Gene from Streptomyces coelicolor A3(2) Controls Antibiotic Biosynthetic Genes (1996)

A 0.972-kilobase pair DNA fragment from Streptomyces lividans that induces the production of the blue-pigmented antibiotic actinorhodine in S. lividans when cloned on a multicopy plasmid has led to the isolation of a 4-kilobase pair DNA fragment from Streptomyces coelicolor containing homologous sequence. Computer-assisted analysis of the DNA sequence revealed three putative open reading frames (ORFs), ORF1, ORF2, and ORF3. ORF2 extends beyond the sequenced DNA fragment, and its deduced product shares no similarities with any other known proteins in the data bases. ORF3 is also truncated, and its 41-amino acid C-terminal product is identical to the S. coelicolor adenine phosphoribosyltransferase. The 847-amino acid ORF1 protein, with a predicted molecular mass of 94.2 kDa, strongly resembled the relA and spoT gene products from Escherichia coli and the homologs from Vibrio sp. strain S14, Haemophilus influenzae, Streptococcus equisimilis H46A, and Mycoplasma genitalium. Unlike these proteins, the ORF1 amino acid sequence analysis revealed the presence of a putative ATP/GTP-binding domain. A mutant was generated by deleting most of the ORF1 gene that showed an actinorhodine-nonproducing phenotype, while undecylprodigiosin and the calcium-dependent antibiotic were unaffected. The mutant strain grew at a much lower rate than the wild-type strain, and spore formation was delayed. When the gene was propagated on a low copy number vector, not only was actinorhodine production restored, but actinorhodine and undecylprodigiosin production was enhanced in both the mutant and wild-type and morphological differentiation returned to wild-type characteristics. (p)ppGpp synthetase activity was not detected in purified ribosomes from the ORF1-deleted mutant, while it was restored by complementation of this strain.
Modeling and Capacity of Polarized MIMO Channels (2008)

In this work the modeling and capacity of a dual polarized (DP) MIMO channel is addressed. The modeling includes channel parameters such as receive and transmit correlation, channel cross-polarization discrimination (XPD), and antenna parameters such as polarization state, polarization parallelity and coupling. The capacity of the DP MIMO channel is evaluated and compared to the capacity of a single polarized (SP) MIMO system. The SP MIMO system with spatially separated antenna sensors has the advantage that it also offers array gain and will therefore during idealized conditions outperform the DP MIMO system. However, in this work it is found that this advantage often is reduced and sometimes even lost when channel and antenna imperfections such as, e.g., correlation, channel XPD, and polarization mismatch are introduced. The main conclusion is that DP antennas might not always yield the best MIMO performance, but instead offer compact antenna solutions for mobile devices and robust performance that is more insensitive to the aforementioned imperfections.
Surface potential imaging for magnetoresistive head development (1997)

We demonstrate the first applications of scanning surface potential microscopy to magnetoresistive (MR) thin-film devices. Images are presented on active devices showing 2D maps of the surface potential of energized MR read-head stripes taken from the production line at the puck level. We have found that surface potential line scans (voltage vs. distance) along MR spin valve stripes show slight deviations from linearity, possibly due to nonuniform film magnetization along the length of the stripe.

Intravenous Grafts Of Amniotic Fluid-Derived Stem Cells Induce Endogenous Cell Proliferation and Attenuate Behavioral Deficits in Ischemic Stroke Rats (2012)

We recently reported isolation of viable rat amniotic fluid-derived stem (AFS) cells [1]. Here, we tested the therapeutic benefits of AFS cells in a rodent model of ischemic stroke. Adult male Sprague-Dawley rats received a 60-minute middle cerebral artery occlusion (MCAo). Thirty-five days later, animals exhibiting significant motor deficits received intravenous transplants of rat AFS cells or vehicle. At days 60-63 post-MCAo, significant recovery of motor and cognitive function was seen in stroke animals transplanted with AFS cells compared to vehicle-infused stroke animals. Infarct volume, as revealed by hematoxylin and eosin (H&E) staining, was significantly reduced, coupled with significant increments in the cell proliferation marker, Ki67, and the neuronal marker, MAP2, in the dentate gyrus (DG) [2] and the subventricular zone (SVZ) of AFS cell-transplanted stroke animals compared to vehicle-infused stroke animals. A significantly higher number of double-labeled Ki67/MAP2-positive cells and a similar trend towards increased Ki67/MAP2 double-labeling were observed in the DG and SVZ of AFS cell-transplanted stroke animals, respectively, compared to vehicle-infused stroke animals. This study reports the therapeutic potential of AFS cell transplantation in stroke animals, possibly via enhancement of endogenous repair mechanisms.
A Fuzzy Representation For Event Occurrence (1990)

Activity recognition systems and their supporting temporal representations typically model the occurrence of an event using numeric values or numeric ranges for start times, finish times, and durations. Such an approach may not adequately reflect the uncertainty and variation experienced in real situations. This paper in-vestigates a more general representation for event duration and start time using fuzzy sets. From this representation, confidence functions are defined in support of reasoning about a sequence of event occurrences. The potential application of this approach to the problem of focus of attention in sensor allocation is discussed.
HIV-gp 160-induced T cell-dependent B cell differentiation. Role of T cell-B cell activation molecule and IL-6 (1993)

The HIV envelope glycoprotein gp160 has been previously demonstrated to induce differentiation of normal B lymphocytes into Ig-secreting cells; the response is T cell-dependent, and T cells pretreated with gp160 can support B cell differentiation. This study investigates the cell surface molecules and cytokines that play a role in the gp160-induced T-B cell interaction. Utilizing CD4+CD45RO+ cloned T cells as the source of helper cells, we observed that physical contact with B cells is essential for the gp160-induced B cell response; no IgG-secretion occurred if T cells were separated from the B cells by culturing them in Transwell chambers. The expression of T cell-B cell activation molecule, a novel surface molecule associated with T cell activation, was moderately increased by gp160, and antibody to T cell-B cell activation molecule abrogated the gp160-mediated Th cell function. Cell surface molecules LFA-1, ICAM-1, HLA-DR, CD28, and B7 were also involved in the T-B cell interaction since mAb to any of these molecules inhibited the gp160-induced B cell differentiation response. gp160 also induced IL-6R and CD23 molecule expression on B cells when added to cultures of T plus B cells; there was CD23 expression only in cells that formed conjugates with T cells. Paraforamaldehyde-fixed, gp160-pretreated T cells failed to elicit IgG responses in B cells, but did induce CD23 and IL-6R up-regulation on B cells. Addition of exogenous IL-6, but not IL-2 or IL-4, restored the IgG secretion. These findings indicate that the T cell dependence for gp160-induced B cell differentiation responses involves two steps: one requires contact-dependent interaction of several cell surface molecules, and the second requires IL-6 secretion.

An Investigation of the Selective Chain Scission at Centered Diels–Alder Mechanophore under Ultrasonication (2017)

It is a challenging topic to disconnect a linear polymer selectively at the mechanophore site by an external force in a "cold" fashion. In this work, the effect of the power output of ultrasonication on the selective cleavage at the centered urfuryl-maleimide Diels–Alder (DA) mechanophore of poly(methyl acrylate)s (DA-PMA-a and DA-PMA-b) were quantitatively investigated by comparative study on experimental and simulated chain scission kinetics as well as high-resolution 1H NMR spectroscopy (600 MHz). At low power output of the ultrasonication (2.10 W), DA-PMA-a with Mn of ca. 2Mlim (Mlim, below which no further chain scission was observed) presented a DI (degradation index)−t (sonication time) plot with a turnover point at ca. 1.0 and no clear variation of the molecular weight after the turnover, which met well with the calculated center cleavage mode. At 5.52 W, DA-PMA-a and a poly(methyl acrylate) that contained two centered ester bonds (ester-PMA) presented similar DI–t plots with turnover points less than 1.0 within same sonication times, while poly(methyl acrylate) with fully carbon–carbon chain (PMA) had a turnover at DI value of ca. 0.5. By way of contrast, high power output of the ultrasonication (5.52 W) caused a possible cleavage of ester bonds of DA-PMA-a, which would mask the selective cleavage at the DA site. High-resolution 1H NMR result of DA-PMA-b (115.8 kDa, Mn was slightly higher than 2Mlim) showed that DA conversions were up to 55% under 2.10 W and 38% under 5.52 W. The kinetics from GPC traces and 1H NMR results of DA-PMA-b as well as 1H NMR results of DA-PMA-c (68.4 kDa, Mn was slightly higher than Mlim) under sonication confirmed the observation that low power output favored selective chain scission at DA site. The turnover point in the DI–t plot might be used as characteristic parameter to gauge the selective chain scission at mechanophore site for single mechanophore-centered polymers.
