Measles infection of human mononuclear cells. I. Acute infection of peripheral blood lymphocytes and monocytes. (1975)

A study of the susceptibility of human peripheral blood mononuclear cells to measles virus infection and replication is reported. Resting lymphocytes obtained from adults showed very low levels of infection and virus replication while lymphocytes activated by plant mitogens or allogenic lymphocytes supported mononuclear cells obtained from the umbilical cord of healthy neonates were more susceptible to measles virus infection than those of adults; however, activated cord lymphocytes supported viral replication in the range observed with adult activated lymphocytes. Monocytes obtained from adults were relatively resistant to measles virus infection and replication while neonatal cord blood monocytes supported viral replication to the degree observed with activated lymphocytes. It is hypothesized that infection of acitivated lymphocytes may explain the depression of cell-mediated immunity seen during acute measles virus infection. The significance of the finding that neonatal monocytes are more susceptible to viral infection and replication than adult monocytes is discussed.
Anthracene‐Fused Oligo‐BODIPYs: A New Class of π‐Extended NIR‐Absorbing Materials (2022)

Abstract Large π‐conjugated systems are key in the area of molecular materials. Herein, we prepare via Au I ‐catalyzed cyclization a series of fully π‐conjugated anthracene‐fused oligo‐BODIPYs. Their structural and optoelectronic properties were studied by several techniques, ranging from X‐ray, UV/Vis, and cyclic voltammetry to transient absorption spectroscopy. As a complement, their electronic structures were explored by means of Density Functional Theory (DFT) calculations. Depending on the size and shape of the π‐conjugated skeleton, unique features—such as face‐to‐face supramolecular organization, NIR absorption and fluorescence as well as strong electron accepting character—were noted. All in all, the aforementioned features render them valuable for technological applications.
Capillary Electrophoresis of Proteins and Peptides (1995)

Capillary electrophoresis (CE) is a high-resolution technique for the separation of a wide variety of molecules of biological interest such as metabolites, drugs, amino acids, nucleic acids, and carbohydrates. This unit focuses on the use of CE to separate proteins and peptides based on charge-to-mass ratios. Separation of proteins based on their isoelectric points is described along with a protocol for optimizing the separation conditions for a given protein. CE is also used for separations of peptides on an analytical scale and as a micropreparative technique--with either multiple separations that are pooled or a single, larger-scale separation--for the isolation of peptides from a protease digestion. In most of these examples the same capillary column can be used for all the separations. Only changes in buffer composition, ionic strength, and the presence or absence of additives are required for each specific application.
A DRM Solution Based on Social Networks and Enabling the Idea of Fair Use (2007)

Fair use policy allows legal owners to share products they bought with their acquaintance; it is based on the assumptions that the owners pass an original product and they cannot use it at the same time. In the digital world, we can hardly apply those assumptions since they are based on a physical availability. Furthermore, digital content providers want to have control over the distribution of their products; thus, Digital Rights Management (DRM) systems do not assist and even forbid sharing. In this paper, we describe a DRM system that takes advantage of a social network. We will describe how a model of an existing on-line social network, which includes users’ roles and trust relationships can be applied. We will present that roles and trust metrics, maintained by the users can be coupled with sharing policies controlled by the content providers. Our solution gives flexibility to the users; it still also leaves, enough control over the content distribution to the content providers. We will show how to extend an existing Digital Rights Language (DRL) to support properties defined in social networks metadata and compare it with other approaches. Finally, we will discuss if our solution introduces the fair use policy to the digital world.

Deposition of silicon films from SiCl4 glow discharges: A kinetic model of the surface process (1987)

The deposition of amorphous silicon films from plasma-chemical reduction of silicon tetrachloride has been studied using optical emission spectroscopy, mass spectrometry, and laser interferometry as diagnostic techniques. The experimental results have been examined using a kinetic model of the surface processes. In the model, silicon tetrachloride (SiCl4) and silicon dichloride (SiCl2), chemisorbed on the growing surface, interact with hydrogen atoms to give free bond silicon species (−SiClx), which are reactive intermediates for the silicon-to-silicon bond formation on the surface. The temperature dependence of the deposition rate in the kinetic region has been also investigated. It has been established that the apparent activation energy for the silicon plasma deposition depends on the electronic character of the material (i.e., undoped, n, and p doped). As the surface becomes boron or phosphorus doped, the value of the apparent activation energy changes with respect to the undoped surface, as a result of the different chemisorption heat on the different surfaces.
<title>Empirical investigation of iterative maximum-entropy spectral estimation of one-dimensional random processes</title> (1992)

In this paper we provide the results of an empirical investigation of iterative maximum entropy spectrum estimation. The Lim-Malik algorithm is compared to the Burg algorithm on a number of analytic as well as practical one-dimensional signals. We study the convergence of the Lim-Malik algorithm and suggest some criteria to assure convergence in the one- dimensional case.
S -band Tm3+-doped tellurite glass microsphere laser via a cascade process (2004)

We present a Tm3+-doped tellurite glass microsphere laser operating in the S band via a cascade process. The microsphere is fabricated by melting the end of a tellurite glass wire, and the microsphere laser is pumped at 800nm using a tapered optical fiber. Laser oscillation is observed simultaneously in the S band and the 1.9μm band. The threshold of lasing in the 1.9μm band is lower than in the S band, and the quantum efficiency in the 1.9μm band increases with pump power above the lasing threshold of the S band.
Tetrathiafulvalene (TTF)-Functionalized Thiophene Copolymerized with 3,3‴-Didodecylquaterthiophene: Synthesis, TTF Trapping Activity, and Response to Trinitrotoluene (2013)

We report a synthesis route to a thiophene polymer where the repeat unit consists of 3,3‴-didodecylquaterthiophene (as in PQT12) plus an additional thiophene ring from which other functional groups may be projected. The hydroxymethyl form of this polymer, while only a poor semiconductor in its own right, serves as a vehicle for compatibilizing PQT12 itself with arbitrary functional groups. In this article, we focus on tetrathiafulvalene (TTF) as the functionality. As expected, the TTF group acts as a hole trap, as shown by loss of hole mobility and a surprising negative Seebeck coefficient, but this enables a current-increase response to trinitrotoluene as an analyte and confirms a similar observation we recently reported for a dissolved TTF. Added dopants also fill the trap states, restoring hole mobility and the typical positive Seebeck coefficient.

Collagen fragments in urine derived from bone resorption are highly racemized and isomerized: a biological clock of protein aging with clinical potential (2000)

Fragments of the α1 C-terminal telopeptide of type I collagen containing the sequence AHDGGR1209-1214 (CTx) can be measured in urine as an index of bone resorption. We report here that these molecules undergo racemization and isomerization of Asp1211in vitro and in vivo, generating a mixture of four isomers: the native peptide form (αL), an isomerized form containing a β-Asp bond (βL), a racemized form containing a D-Asp residue (αD) and an isomerized/racemized form (βD). To study these reactions at this specific site in collagen, we have employed four immunoassays, each specific for one of the isoforms, and developed HPLC methods for their separation. The kinetics of these reactions were studied in vitro under physiological conditions by incubation of synthetic AHDGGR hexapeptide or mineralized bone collagen. Reactions were found to be strongly shifted towards the β-Asp forms and slightly in favour of the D-enantiomeric forms. CTx isomers were measured in human urine and in enzymic digests of bovine bone collagen. The results indicated that the extent of racemization and isomerization were correlated with the age and turnover of collagen. The ratios between the native and age-related forms of CTx were elevated in urine from patients with Paget's disease or osteoporosis as compared with that from healthy adults. The αL/αD CTx ratio had the highest discriminatory power (T-score = 23.2; P < 0.0001 and T-score = 1.5; P < 0.0001 for Paget's disease and osteoporosis respectively). In conclusion, these findings indicate that an assessment of CTx ratios in urine may provide an estimate of bone turnover, aiding in the diagnosis of metabolic bone diseases.
A New Source-to-sink Approach to Petroleum Systems and Prospectivity Evaluation in Deepwater: Case Study from Sabah (2015)

Summary The interaction between deformation and erosion in mountain belts on one hand, and transport and sedimentation in basin areas on the other hand, can be used as prognosis tools in petroleum exploration. In our workflow, we combine 3D seismic, experimental modelling, 2D structural restoration, CSEM imaging and magnetic analysis to study these interactions and feedback. Detailed images of the seafloor from 3D seismic data allowed the interpretation of sediment fluxes, based on analogical modelling of drainage networks. Geomechanics-based restoration was used to decipher the structural features at depth interpreted from seismic lines and reduced the uncertainty on the deformation timing. Where seismic data is of poor quality at depth and where a high rate of fault segmentation occurs, magnetics and CSEM permit along-strike correlation. We demonstrate that we can distinguish regional tectonic deformations and gravitydriven deformations using this integrated approach. Also the petroleum system which is a component of the drainage network, responds as a mirror effect of the coupling between Earth’s surface processes and deep crustal deformation. This new approach is illustrated in NW offshore Borneo and can be applied in hydrocarbon exploration in other continental margin.
Fine-Needle Aspiration Cytology in the Preoperative Diagnosis of Thyroid Nodules (1977)

Fifty consecutive patients were studied to assess the utility of fine-needle aspiration cytology for the diagnosis of hypofunctioning thyroid nodules. In two patients, cysts were evacuated and did not recur. Thirty-three patients underwent excisional biopsy; the aspiration biopsy result was not a criterion for surgery. Satisfactory aspiration specimens were obtained in 32 patients (97%). The diagnosis in nine aspiration specimens was malignant; of these seven (78%) were correct and there was one false-positive and one occult carcinoma unrelated to the clinically detected nodule. Five aspirations showed suspected malignancy; of these, two were carcinoma, one was an occult carcinoma, and two were benign. Eighteen aspirations were interpreted as benign; of these, 17 (94%) were correct and the one false-negative diagnosis was a well-differentiated follicular carcinoma. The procedure is useful in assessing the need for surgery in high-risk patients and in selecting patients for thyroid-suppression therapy.
Temperature Dependence of Radial Breathing Mode Raman Frequency of Single-Walled Carbon Nanotubes (2003)

Recent high-temperature studies of Raman-active modes in single-walled carbon nanotube (SWNT) bundles report a softening of the radial and tangential band frequencies with increasing sample temperature. A few speculations have been proposed in the past to explain the origin of these frequency downshifts. In the present study, based on experimental data and the results of molecular dynamics simulations, we estimate the contributions from three factors that may be responsible for the observed temperature dependence of the radial breathing mode frequency $[{\ensuremath{\omega}}_{\mathrm{RBM}}(T)].$ These factors include thermal expansion of individual SWNTs in the radial direction, softening of the C-C (intratubular) bonds, and softening of the van der Waals intertubular interactions in SWNT bundles. Based on our analysis, we find that the first factor plays a minor role due to the very small value of the radial thermal expansion coefficient of SWNTs. On the contrary, the temperature-induced softening of the intra- and intertubular bonds contributes significantly to the temperature-dependent shift of ${\ensuremath{\omega}}_{\mathrm{RBM}}(T).$ For nanotubes with diameters $(d)g~1.34\mathrm{nm},$ the contribution due to the radial thermal expansion is \ensuremath{\leqslant}4% over the temperature range used in this study. Interestingly, this contribution increases to \ensuremath{\geqslant}10% in the case of nanotubes having $dl~0.89\mathrm{nm}$ due to the relatively larger curvature of these nanotubes. The contributions from the softening of the intra- and intertubular bonds are approximately equal. These two factors together contribute a total of about \ensuremath{\sim}95% and 90%, respectively, for SWNTs having $dg~1.34\mathrm{nm}$ and \ensuremath{\leqslant}0.89 nm.

In vitro immunization of human lymphocytes with human lung cancer cell line A549 (1992)

We established a method of in vitro immunization of human lymphocytes against human cancer cells and efficiently obtained human-human hybridomas producing cancer-specific antibodies using the in vitro immunized lymphocytes. Human lymphocytes were cocultured with human lung cancer cell line A549 for four days in medium containing various immunoactive reagents. In vitro immunization was effectively caused by the addition of OK-432 or muramyl peptides, IL-2, and IL-6, to the coculture of A549 cells and lymphocytes. Although specific antibodies of both IgM and IgG classes were produced by this method, the ratio of IgG to IgM was greater than or equal to 2. The efficiencies of in vitro immunization fluctuated about threefold in lymphocytes derived from several donors. The in vitro immunized lymphocytes were fused with human fusion partner A4H12 cells. Hybridomas producing specific antibodies reactive to A549 cells were efficiently obtained by sequential cell fusion. The efficiency of acquisition of hybridomas producing specific antibodies with the in vitro immunized lymphocytes was about 10-fold higher than that with lymphocytes spontaneously immunized in bodies of lung cancer patients.
Steady state properties of far from equilibrium diffusive systems (1981)

A stochastic model is proposed for the study of the effect of the interactions on transport through a system placed between two parallel external baths. The exchange of matter of a system at local equilibrium with a single external bath is conveniently treated with the help of a stochastic theory described previously. That theory is extended here to the case of a system placed between two parallel external baths. The extension is realized as follows. The system is viewed as an array, perpendicular to the external gradient, of hypothetical layers at local equilibrium. Each layer exhibits a ’’two-faced exchange,’’ exchanging matter with two baths (viz., layers on its two sides) and provides, in turn, a bath to these two layers. The theory is applied to a study of the steady state properties of far from equilibrium systems composed of two and of three molecular species. It is shown that, in the case of a binary system, our two-faced exchange model leads to an equilibrium in each layer, whatever the value of the external gradient. However, that convenient feature evaporates on passing to systems with more than two molecular species. The effect of the interactions on the stationary flows and concentration profiles is extensively studied. The relevance of our results to the diffusion of hydrogen through palladium is also discussed.

RF performances of inductors integrated on localized p+-type porous silicon regions (2012)

To study the influence of localized porous silicon regions on radiofrequency performances of passive devices, inductors were integrated on localized porous silicon regions, full porous silicon sheet, bulk silicon and glass substrates. In this work, a novel strong, resistant fluoropolymer mask is introduced to localize the porous silicon on the silicon wafer. Then, the quality factors and resonant frequencies obtained with the different substrates are presented. A first comparison is done between the performances of inductors integrated on same-thickness localized and full porous silicon sheet layers. The effect of the silicon regions in the decrease of performances of localized porous silicon is discussed. Then, the study shows that the localized porous silicon substrate significantly reduces losses in comparison with high-resistivity silicon or highly doped silicon bulks. These results are promising for the integration of both passive and active devices on the same silicon/porous silicon hybrid substrate.
Frame rate reduction of depth cameras by RGB-based depth prediction (2016)

Depth cameras are becoming widely used for facilitating fast and robust natural user interaction. But measuring depth can be high in power consumption mainly due to the active infrared illumination involved in the acquisition process, for both structured-light and time-of-flight technologies. It becomes a critical issue when the sensors are mounted on hand-held (mobile) devices, where power usage is of the essence. A method is proposed to reduce the depth acquisition frame rate, possibly by factors of 2 or 3, thus saving considerable power. The compensation is done by calculating reliable depth estimations using a coupled color (RGB) camera working at full frame rate. These predictions, which are shown to perform outstandingly, create for the end user or application the perception of a depth sensor working at full frame rate. Quality measures based on skeleton extraction and depth inaccuracy are used to calculate the deviation from the ground truth.
Droplet Motion Control on Dynamically Hydrophobic Patterned Surfaces as Multifunctional Liquid Manipulators (2017)

In this letter, we introduce a novel liquid manipulation strategy to design dynamically hydrophobic and statically hydrophobic/hydrophilic patterned surfaces using an "omniphobicity"-based technique. The surfaces guide the sliding direction of a droplet in the presence of a statically hydrophilic area where the droplet does not stick on the transport path significantly enhancing the fluidic system transport efficiency. The concept of dynamically hydrophobic and statically hydrophobic/hydrophilic patterned surfaces in conjunction with omniphobic patterning techniques having surface multifunctionality, we believe, has potential not only for fluidic applications but also for future material engineering development.
The Conservative Therapy of Odontogenic Keratocyst in the Mandible Combined with Surgical Procedure (1981)

Odontogenic keratocyst arises from proliferation of residues of the dental lamina. The term "odontogenic keratocyst" was introduced by Philipsen (1956). This cyst differs clinically and histologically from the majority of the odontogenic cysts. In general, the lining of odontogenic keratocyst consists of stratified squamous epithelium with absence of rete pegs. The odontogenic keratocyst of the mandible in a 46-year-old man was treated by total enucleation of the right ramus and part of the body of the mandible. Our surgical procedure of decortication and subsequent replacement of bone is a modification of the osteoplastic operation technique described by Moose (1952) and Liposky (1980).
