Dynamic Heterogeneity in Poly(vinyl methyl ether)/Poly(2-chlorostyrene) Blends (2006)

Dielectric spectroscopy was used to follow the component dynamics in the miscible blend of poly(vinyl methyl ether) (PVME) and poly(2-chlorosytrene) (P2CS). For the PVME component (which has the more intense loss peak due to its higher polarity), the shape of the segmental relaxation peak depends only on the relaxation time and is otherwise independent of thermodynamic conditions. This is in accord with the general behavior of neat materials. By measuring the spectra as a function of both temperature and pressure, the relative effect of temperature and volume on the segmental relaxation times was quantified from ratio of the isochoric and isobaric activation enthalpies. This ratio is essentially the same for the neat polymers, but blending has a disparate effect of the components: volume effects become stronger for the PVME but are diminished for P2CS. Similarly, the fragilities of the neat components are quite close but change markedly in the blend. The P2CS component has a fragility of 32, which is lower than found for any neat polymer. In comparison to the segmental dynamics, transport of mobile ions in the blend is relatively insensitive to volume (or pressure). These effects are reflected in the magnitude of the respective exponents of the scaling function, which enables collapse of the relaxation times onto single, component-specific master curves.
The Bose-einstein Condensation of Positronium in Submicron Cavities (2005)

We have considered the possibility of creating a matter-antimatter Bose-Einstein condensate in the laboratory and concluded that a committed and focussed program could succeed in making this new “extraordinary” material available for scientific study. In this paper we describe the experimental requirements of the scheme and the mechanisms by which a positronium Bose-Einstein condensate may be both formed and observed.

Data from <i>MLL</i>-Rearranged B Lymphoblastic Leukemias Selectively Express the Immunoregulatory Carbohydrate-Binding Protein Galectin-1 (2023)

&lt;div&gt;Abstract&lt;p&gt;&lt;b&gt;Purpose:&lt;/b&gt; Patients with mixed lineage leukemia (&lt;i&gt;MLL&lt;/i&gt;)–rearranged B-lymphoblastic leukemias (B-ALL) have an unfavorable prognosis and require intensified treatment. Multiple &lt;i&gt;MLL&lt;/i&gt; fusion partners have been identified, complicating the diagnostic evaluation of &lt;i&gt;MLL&lt;/i&gt; rearrangements. We analyzed molecular markers of &lt;i&gt;MLL&lt;/i&gt; rearrangement for use in rapid diagnostic assays and found the immunomodulatory protein, Galectin-1 (Gal-1), to be selectively expressed in &lt;i&gt;MLL&lt;/i&gt;-rearranged B-ALL.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Experimental Design:&lt;/b&gt; Transcriptional profiling of ALL subtypes revealed selective overexpression of Gal-1 in &lt;i&gt;MLL&lt;/i&gt;-rearranged ALLs. For this reason, we analyzed Gal-1 protein expression in &lt;i&gt;MLL&lt;/i&gt;-germline and &lt;i&gt;MLL&lt;/i&gt;-rearranged adult and infant pediatric B-ALLs and cell lines by immunoblotting, immunohistochemistry, and intracellular flow cytometry of viable tumor cell suspensions. Because deregulated gene expression in &lt;i&gt;MLL&lt;/i&gt;-rearranged leukemias may be related to the altered histone methyltransferase activity of the &lt;i&gt;MLL&lt;/i&gt; fusion protein complex, we also analyzed histone H3 lysine 79 (H3K79) dimethylation in the &lt;i&gt;LGALS1&lt;/i&gt; promoter region using chromatin immunoprecipitation.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Results:&lt;/b&gt; Gal-1 transcripts were significantly more abundant in &lt;i&gt;MLL&lt;/i&gt;-rearranged B-ALLs. All 32 primary &lt;i&gt;MLL&lt;/i&gt;-rearranged B-ALLs exhibited abundant Gal-1 immunostaining, regardless of the translocation partner, whereas only 2 of 81 germline-&lt;i&gt;MLL&lt;/i&gt; B-ALLs expressed Gal-1. In addition, Gal-1 was selectively detected in newly diagnosed &lt;i&gt;MLL&lt;/i&gt;-rearranged B-ALLs by intracellular flow cytometry. The &lt;i&gt;LGALS1&lt;/i&gt; promoter H3K79 was significantly hypermethylated in &lt;i&gt;MLL&lt;/i&gt;-rearranged B-ALLs compared with &lt;i&gt;MLL&lt;/i&gt;-germline B-ALLs and normal pre-B cells.&lt;/p&gt;&lt;p&gt;&lt;b&gt;Conclusion:&lt;/b&gt; In B-ALL, Gal-1 is a highly sensitive and specific biomarker of &lt;i&gt;MLL&lt;/i&gt; rearrangement that is likely induced by a MLL-dependent epigenetic modification.

Interface properties and effective work function of Sb‐predoped fully silicided NiSi gate (2008)

Abstract X‐ray photoelectron spectroscopy (XPS) analysis of Sb‐predoped fully silicided (FUSI) NiSi gate metal‐oxide‐semiconductor structure was carried out to evaluate the chemical bonding states and location of Sb pileup at NiSi/SiO 2 interface. The results reveal that Sb atoms encroach into the SiO 2 layer and that their pileup is formed at about 3 nm beneath the NiSi/SiO 2 interface. Direct measurement of the work function of Sb‐doped FUSI NiSi gate by XPS suggests that the work function is identical to its original value without the Sb pileup located inside the gate oxide.

Localization of fluorescence marked prostate tumor with time- resolved diffuse optical tomography (2010)

To increase prostate cancer diagnosis sensibility, we propose to add an optical modality to an US biopsy tool to localize fluorophore marked tumors. Optical signals are acquired on a time-resolved acquisition chain composed by a 770 nm femtosecond laser source and a four channels TCSPC device. The fluorescence concentration is reconstructed by using intensity and mean time of flight acquired from each time-resolved source-detector signal. Validation experiments are performed on a phantom mimicking prostate both on its optical and ultrasound properties with 10 &mu;mol/L ICG 1 cm deep double fluorescent inclusions to simulate marked tumors. An exhaustive search algorithm succeeded in reconstructing the two distinct fluorescence dots with correct locations.
Sputter Depth‐Profile Study of Accelerated Interface Mixing by Thermal Annealing in Solution‐Processed Organic Light‐Emitting Diodes (2018)

Abstract The effect of thermal annealing on interfacial mixing of solution‐processed organic light‐emitting diodes (OLEDs) using direct sputter‐depth profiling techniques is investigated. X‐ray and ultraviolet photoelectron spectroscopy and argon gas cluster ion beam sputtering are used to investigate the distribution of chemical species near the interface. Extensive interfacial mixing is found in solution‐processed OLEDs after the thermal annealing at temperatures below the glass transition temperature of the organic material, while such mixing is not evident in vapor‐deposited devices. It is found that there is a partially mixed interface in the solution‐processed devices prior to the annealing, which seems to promote effective interdiffusion during the annealing. Surprisingly, the extensive interfacial mixing after the thermal annealing appears to significantly enhance the efficiency of OLEDs.

Inability of a Mouse Cell Line Transformed to Produce Biologically Active Recombinant Human Insulin-Like Growth Factor I (IGF-I) to Respond to Exogenously Added IGF-I (1988)

A plasmid expression vector encoding human insulin-like growth factor I (hIGF-I) in the form of a 97-amino acid precursor protein containing the first 27 amino acids of prebovine GH and the 70 amino acids of hIGF-I has been used to transform mouse L cells. A stably transformed mouse L cell clone has been isolated which expresses and secretes hIGF-I. The secreted peptide comprises 3% of the protein in conditioned medium. IGF-I can be purified to homogeneity in 2 chromatographic steps. One liter of conditioned medium yields approximately 200 micrograms purified peptide. Amino-terminal sequence analysis confirms that the signal peptide has been proteolytically hydrolyzed from the precursor protein before secretion to form [Ala0]hIGF-I. The recombinant peptide and serum-derived hIGF-I are equipotent as inhibitors of the binding of [125I]IGF-I to the type 1 receptor of human placenta and to a crude preparation of acid-stable human serum binding proteins. The peptides are equipotent in 2 in vitro assays, the stimulation of the rate of 2-[1,2-N-3H]deoxyglucose transport in BC3H1 cells and the stimulation of [methyl-3-3H]thymidine incorporation into DNA in A10 cells. In contrast to a control mouse L cell line, DNA synthesis in the [Ala0]IGF-I-secreting line is completely unresponsive to [Thr59]IGF-I, while it responds normally to calf serum (10%). Thus, the [Ala0]IGF-I-secreting line is selectively desensitized to IGF-I. The binding of [125I]IGF-I to both lines is identical, indicating that the loss of responsiveness to IGF-I is not due to a loss of cell surface receptor. The ability to render mouse L cells unresponsive to IGF-I is transferred in the conditioned medium of the [Ala0]IGF-I-secreting cell line. In addition, pretreatment of control cells with [Thr59]IGF-I (10 nM) results in attenuation of the response to a subsequent dose of IGF-I. These data indicate that prolonged exposure to high levels of IGF-I may cause a postreceptor-mediated desensitization to IGF-I. Alternatively, IGF-I may promote secretion of an inhibitor of IGF-mediated DNA synthesis.
Room-Temperature Exciton Storage in Elongated Semiconductor Nanocrystals (2007)

The excited state of colloidal nanoheterostructures consisting of a spherical CdSe nanocrystal with an epitaxially attached CdS rod can be perturbed effectively by electric fields. Field-induced fluorescence quenching coincides with a conversion of the excited state species from the bright exciton to a metastable trapped state (dark exciton) characterized by a power-law luminescence decay. The conversion is reversible so that up to 10% of quenched excitons recombine radiatively post turn-off of a 1 micro s field pulse, increasing the delayed luminescence by a factor of 80. Excitons can be stored for up to 10(5) times the natural lifetime, opening up applications in optical memory elements.

Impact of Transponder Architecture on the Scalability of Optical Nodes in Elastic Optical Networks (2013)

The elastic optical network has proven to be a promising network architecture for handling the rapid growth in IP traffic in the optical layer in a spectrum-efficient manner. This study reveals the optical node requirements in elastic optical networks by comparing multiple network architectures using an integrated resource allocation scheme that considers both network and node parameters. Evaluations show that the multi-flow (MF) transponder-based elastic optical network architecture is superior to two other architectures in terms of scalability of optical nodes and network costs.
Resiliency policies in access control (2006)

We introduce the notion of resiliency policies in the context of access control systems. Such policies require an access control system to be resilient to the absence of users. An example resiliency policy requires that, upon removal of any s users, there should still exist d disjoint sets of users such that the users in each set together possess certain permissions of interest. Such a policy ensures that even when emergency situations cause some users to be absent, there still exist independent teams of users that have the permissions necessary for carrying out critical tasks. The Resiliency Checking Problem determines whether an access control state satisfies a given resiliency policy. We show that the general case of the problem and several subcases are intractable (NP-hard), and identify two subcases that are solvable in linear time. For the intractable cases, we also identify the complexity class in the polynomial hierarchy to which these problems belong. We discuss the design and evaluation of an algorithm that can efficiently solve instances of nontrivial sizes that belong to the intractable cases of the problem. Finally, we study the consistency problem between resiliency policies and static separation of duty policies.
Shape classification through structured learning of matching measures (2009)

Many traditional methods for shape classification involve establishing point correspondences between shapes to produce matching scores, which are in turn used as similarity measures for classification. Learning techniques have been applied only in the second stage of this process, after the matching scores have been obtained. In this paper, instead of simply taking for granted the scores obtained by matching and then learning a classifier, we learn the matching scores themselves so as to produce shape similarity scores that minimize the classification loss. The solution is based on a max-margin formulation in the structured prediction setting. Experiments in shape databases reveal that such an integrated learning algorithm substantially improves on existing methods.
Ultrasound-inducible fluorescent particles for internal tattooing (2009)

Our objective is to selectively and non-invasively deposits markers under image guidance for internal tattooing. This study describes the production of ultrasound-inducible particles carrying large payloads of fluorescent markers and the in vivo proof of concept of their remote deposit via focused ultrasound. The particles are double emulsions produced in a microfluidic system, consisting of aqueous fluorescein in perfluorocarbon in water. The vaporization threshold of these particles is measured with a 2.25 MHz transducer focused in an Opticell plate and observed under an inverted fluorescence microscope. The composite particles are monodisperse with a diameter of 5 microns. Fluorescein-containing water represents about 70% of the particles content and they are stable for weeks. When submitted to 2.25 MHz pulses, the particles vaporize at 4 MPa peak-negative pressure. During disruption, jets of fluorescein are generated. After several seconds, a brightly fluorescent dot (0.5 mm diameter) is observed at the focus of the transducer. Experiments in the chorioallantoique membrane of chicken eggs demonstrate that sufficient fluorescein can be released allows the observation by the naked eye. This localized internal tattooing could help surgeons identify tissue previously highlighted under image guidance.

Production of carbon molecular sieves from Illinois coal. Final technical report, 1 September, 1992--31 August 1993 (1993)

Carbon molecular sieves (CMS) have become an increasingly important class of adsorbents for use in gas separation and recovery processes. The overall objective of this project is to determine whether Illinois Basin coals are a suitable feedstock for the production of CMS and to evaluate the potential application of these products in commercial gas separation processes. In Phase 1 of this project, gram quantities of char were prepared from Illinois coal in a fixed-bed reactor under a wide range of pyrolysis and activation conditions. Chars having surface areas of 1,500--2,100 m{sup 2}/g were produced by chemical activation using potassium hydroxide (KOH) as the chemical activant. These high surface area (HSA) chars had more than twice the adsorption capacity of commercial molecular sieves. The kinetics of adsorption of various gases, e.g., O{sub 2}, N{sub 2}, CO{sub 2}, CH{sub 4}, and H{sub 2}, on these chars at 25 C was determined. Several chars showed good potential for efficient O{sub 2}/N{sub 2}, CO{sub 2}/CH{sub 4} and CH{sub 4}/H{sub 2} separation. In Phase 2 of this project, larger quantities of char are being prepared from Illinois coal in a batch fluidized-bed reactor and in a continuous rotary tube kiln. The ability of these chars to separate binary gas mixtures is tested in an adsorption column/gas chromatography system. Oxygen and nitrogen breakthrough curves obtained for selected chars were compared to those of a commercial zeolite. Selected chars were subjected to a nitric acid oxidation treatment. The air separation capability of nitric acid treated char was strongly dependent on the outgassing conditions used prior to an O{sub 2}/N{sub 2} adsorption experiment. An outgassing temperature of 130--160 C produced chars with the most favorable air separation properties. 61 refs.
Precision extruding deposition and characterization of cellular poly‐ε‐caprolactone tissue scaffolds (2004)

Successes in scaffold guided tissue engineering require scaffolds to have specific macroscopic geometries and internal architectures to provide the needed biological and biophysical functions. Freeform fabrication provides an effective process tool to manufacture many advanced scaffolds with designed properties. This paper reports our recent study on using a novel precision extruding deposition (PED) process technique to directly fabricate cellular poly‐ε_rm;‐caprolactone (PCL) scaffolds. Scaffolds with a controlled pore size of 250 μ m and designed structural orientations were fabricated.

Quality Obfuscation for Error-Tolerant and Adaptive Hardware IP Protection (2019)

Ahstract-Various attacks on hardware intellectual properties (IPs) have been successful in obtaining design information that can be used to reverse engineer a system, create counterfeits, or insert hardware Trojans. Key-based hardware obfuscation is an attractive solution that helps prevent such attacks. In this paper, for the first time, we propose a key error tolerant obfuscation approach that achieves graceful degradation in output Quality of Service (QoS) as the bit error rate (BER) in obfuscation key increases. The approach, which we refer to it as, “Quality Obfuscation”, is applicable to a large variety of IPs, including digital signal processing (DSP) and approximating computing IPs, which are resilient to output QoS degradation. We present a complete obfuscation framework that can be adapted to any error tolerance rate. To demonstrate its robustness, we obfuscate several common DSP IP blocks and observe the performance under various percentages of bit-flips in the key. We show that our approach provides controllability of system quality, as well as the strong protection at low overhead, e.g., average 15% area and 5.9% power overhead to tolerate 10% BER.
