Differential Induction of Sister Chromatid Exchange by Chemical Carcinogens in Lymphocytes Cultured from Patients with Solid Tumors (1982)

Three carcinogens with different requirements for activation were used to generate sister chromatid exchange (SCE) in cultured lymphocytes from 22 untreated patients with solid tumors. These data were compared to SCEs produced by incubating lymphocytes, from 44 normal persons, with the same carcinogens. In vitro treatments with butadiene epoxide (0.125 micrograms/ml) show no significant differences in the SCEs generated. However, in vitro treatment with mitomycin-C (0.04 micrograms/ml) did induce significant differences (p less than 0.05) in the distribution of the SCE scores. Treatment of the cultured cells with benzo(a)pyrene (10 micrograms/ml), a carcinogen requiring extensive metabolic activation, significantly (p less than 0.001) altered the distribution of the SCEs generated in vitro. The SCE data suggest that metabolic activities play an important role in the processing of carcinogens in solid tumor patients.
Studies on artifacts of the Katsevich algorithm for spiral cone-beam CT (2004)

Recently, Katsevich proposed an exact filtered backprojection (FBP) algorithm to solve the long object problem. Although the Katsevich algorithm is theoretically error-free, it may produce image artifacts if its numerical implementation is not well designed. To evaluate the Katsevich algorithm, we implement it in planar detector geometry. Then, we study four types of image artifacts associated with the numerical implementation of this algorithm, which are <i><b>“texture”, “streak”, “shadow”</b></i> and <i><b>“winkle”</b></i> artifacts. The <b><i>“texture”</i></b> artifacts appear if the endpoints of the PI-Line are not treated appropriately. The <i><b>“streak”</b></i> artifacts are caused by an inadequate number of filtering lines <b><i>Q</i></b>, which can be reduced by setting 0.3<i>N</i><<i><b>Q</b></i><0.7<i>N</i>. In the step of Hilbert filtering, the aliasing effect results in <b><i>“shadow”</i></b> artifacts if the window is not truncated properly. The <b><i>“wrinkle”</i></b> artifacts are due to both the interpolation and difference operators, which may be minimized using more sophisticated interpolation methods, increasing projection data and using a more accurate derivative formula. Our results should be valuable to apply the Katsevich algorithm optimally for practical spiral cone-beam CT.
Diammonium‐Mediated Perovskite Film Formation for High‐Luminescence Red Perovskite Light‐Emitting Diodes (2022)

3D mixed-halide perovskite-based red emitters combine excellent charge-transport characteristics with simple solution processing and good film formation; however, light-emitting diodes (LEDs) based on these emitters cannot yet outperform their nanocrystal counterparts. Here the use of diammonium halides in regulating the formation of mixed bromide-iodide perovskite films is explored. It is found that the diammonium cations preferentially bond to Pb-Br, rather than Pb-I, octahedra, promoting the formation of quasi-2D phases. It is proposed that the perovskite formation is initially dominated by the crystallization of the thermodynamically more favorable 3D phase, but, as the solution gets depleted from the regular A cations, thin shells of amorphous quasi-2D perovskites form. This leads to crystalline perovskite grains with efficiently passivated surfaces and reduced lattice strain. As a result, the diammonium-treated perovskite LEDs demonstrate a record luminance (10745 cd m<sup>-2</sup> ) and half-lifetime among 3D perovskite-based red LEDs.
Simultaneous Fabrication of Vertical and 45° Mirrors of InP for Surface-Emitting Lasers Using Inclined Cl Ion Beams (1991)

Reactive ion beam etching (RIBE) of InP using inclined Cl ion beams has been studied. Straight-sloping side walls of InP grooves are fabricated using those of SiO 2 as etching masks. By controlling the wall inclination of the SiO 2 mask and the etch rate ratio of InP to SiO 2 , an InP groove with side-wall inclinations of 90° and 45° is obtained using one RIBE process. Furthermore, the walls of the groove are used for fabrication of the InGaAsP/InP surface-emitting laser with a Fabry-Perot resonator and a 45° mirror. A threshold current of 40 mA is obtained for the laser under continuous-wave operation at room temperature.

Feedback derived from 3D Accelerometers used for Autonomous Correction of Chest Compression Movement in Cardiopulmonary Resuscitation Training (2014)

This paper reports on an exploration whether feedback, derived from the comparison of a programmed baseline and actual chest compressions during cardiopulmonary resuscitation (CPR), will help trainees to improve their chest compression movement without the need for personal training by a coach. A prototype is constructed that is used to investigate if it is possible to reliably detect chest compression movement and derive feedback from the comparison of that movement to a programmed baseline. Several methods to present the resulting feedback are implemented as well. An experiment is set up to test these feedback methods and to see how well the derived feedback allows the trainees to improve their skills. The results show that reliable feedback can be derived from the 3D accelerometer of a SunSPOT device attached to the back of the hand of the person performing chest compressions. It is also shown that trainees markedly improve their chest compression-skills after the feedback is presented to them. The method of feedback that uses audio is preferred by trainees, but measurements show a combination of audio, text and LED-based feedback leads to the greatest improvement of chest compression skills.

Frequency deviation measurement based on two-arm delta-sigma modulated bridge (2002)

A method of frequency deviation measurement is presented. This two-arm bridge method is based on the use of the delta-sigma modulation and arithmetic operations on two synchronous delta-sigma modulated pulse streams. The simulation results showed a linear relationship between frequency deviation and pulse count.
ISOTOPIC AND ELEMENTAL COMPOSITION OF PLUTONIUM/AMERICIUM OXIDES INFLUENCE PULMONARY AND EXTRA-PULMONARY DISTRIBUTION AFTER INHALATION IN RATS (2010)

The biodistribution of plutonium and americium has been studied in a rat model after inhalation of two PuO(2) powders in lungs and extra-pulmonary organs from 3 d to 3 mo. The main difference between the two powders was the content of americium (approximately 46% and 4.5% of total alpha activity). The PuO(2) with a higher proportion of americium shows an accelerated transfer of activity from lungs to blood as compared to PuO(2) with the lower americium content, illustrated by increased urinary excretion and higher bone and liver actinide retention. The total alpha activity measured reflects mostly the americium biological behavior. The activity contained in epithelial lining fluid, recovered in the acellular phase of broncho-alveolar lavages, mainly contains americium, whereas plutonium remains trapped in macrophages. Epithelial lining fluid could represent a transitional pulmonary compartment prior to translocation of actinides to the blood and subsequent deposition in extra-pulmonary retention organs. In addition, differential behaviors of plutonium and americium are also observed between the PuO(2) powders with a higher dissolution rate for both plutonium and americium being obtained for the PuO(2) with the highest americium content. Our results indicate that the biological behavior of plutonium and americium after translocation into blood differ two-fold: (1) for the two actinides for the same PuO(2) aerosol, and (2) for the same actinide from the two different aerosols. These results highlight the importance of considering the specific behavior of each contaminant after accidental pulmonary intake when assessing extra-pulmonary deposits from the level of activity excreted in urine or for therapeutic strategy decisions.

Synthesis of cyclitol-based glucosidase inhibitors (2010)

The first conduritol aziridine (1,2-dideoxy-1,2-epimino-myo-inositol, 1) was synthesized in seven steps from myo-inositol (2) and inhibits pABG5 β-glucosidase and yeast ⍺-glucosidase irreversibly. 1,2-0-Cyclohexylidene-myo-inositol (3) was obtained by reaction of 2 with cyclohexanone. Benzylation of 3 followed by hydrolysis of the ketal gave l,4,5,6-tetra-0-benzyl-myo-inositol (5). The two free hydroxyl groups in 5 were methanesulfonylated and the axial mesyl group in l,4,5,6-tetra-0-benzyl-2,3-di-0-methanesulfonyl-myo-inositol (12) was selectively displaced by an azido group. The resulting 1-azido-2,3,4,5-tetxa-0-benzyl-1-deoxy-6-0-methanesulfonyl-scyllo-inositol (13) was hydrogenated in the presence of HC1 to give 1-amino-1-deoxy-2-0-methanesulfonyl-scyllo-inositol (24) hydrochloride. Cyclisation of 24 under basic aqueous conditions yielded DL-1. [Formula Omitted] The dissociation constant Ki and the inactivation rate constant ki for inactivation of pABG5 β-glucosidase by 1 were calculated to be 3.0 mM and 0.077 min⁻¹ respectively. For yeast ⍺-glucosidase inactivation, values of Ki, and ki were found to be 9.5 mM and 0.39 min-1 respectively. Finally, 24 and 31 were tested as reversible (non-covalent) inhibitors of both the glucosidases and the respective inhibition constants (Ki) determined.

Syntheses and structures of new copper(I)–indium(III)–selenide clusters † (2000)

The reaction of Se(SiMe3)2 with mixtures of copper(I) chloride and indium(III) chloride in the presence of phosphine ligands PR3 (R = organic group) yielded the new clusters [Cu6In8Se13Cl4(PPh3)6(C4H8O)] 1, [Cu6In8Se13Cl4(PnPr2Ph)12] 2 and [Cu11In15Se16(SePh)24(PPh3)4] 3. The molecular structures of 1, 2 and 3 have been characterised by X-ray crystallography and compared with the chalcopyrite structure of bulk CuInSe2. UV-VIS Solid state absorption spectra have been measured for 1 and 3.
<title>Improved detection model for DCT coefficient quantization</title> (1993)

A detection model is developed to predict visibility thresholds for discrete cosine transform coefficient quantization error, based on the luminance and chrominance of the error. The model is an extension of a previously proposed luminance-based model, and is based on new experimental data. In addition to the luminance-only predictions of the previous model, the new model predicts the detectability of quantization error in color space directions in which chrominance error plays a major role. This more complete model allows DCT coefficient quantization matrices to be designed for display conditions other than those of the experimental measurements: other display luminances, other veiling luminances, other spatial frequencies (different pixel sizes, viewing distances, and aspect ratios), and other color directions.
Device Free Indoor Localization Using Discriminant Features of CSI A Canonical Correlation Paradigm (2018)

With the growth of context-aware computing, Indoor localization based on Wi-Fi signals is gaining popularity due to the widespread deployment of Wi-Fi infrastructure. In this paper, we propose DisLoc, the first discriminant feature based device free indoor localization using canonical correlation analysis. The system exploits the Channel State Information (CSI), which is richer in information related to position than traditional Received Signal Strength (RSS). The DisLoc models localization as a pattern matching problem and addresses the problem of comparing sets of CSI feature matrix for indoor 10-calization, where the sets represent variations in features in terms of CSI amplitude due to the presence of a subject at a particular location. A discriminative feature extraction is proposed for pattern matching using Canonical Correlation Analysis (CCA). Specifically, the system utilizes Principal Component Analysis (PCA) and Linear Discriminant Analysis (LDA) of CSIs as two features into the correlation analysis and performs an effective feature fusion by maximizing the pairwise correlations across the two feature sets. Finally a similarity measure is performed to find the best match for localization. Experimental results show that DisLoc can estimate location in a device free setting with high accuracy which outperforms other state-of-the-art approaches.
Fabrication and Characterization of Electrospun Thermoplastic Polyurethane/Fibroin Small-Diameter Vascular Grafts for Vascular Tissue Engineering (2016)

The demand for small-diameter blood vessel substitutes has been increasing due to a shortage of autograft vessels and problems with thrombosis and intimal hyperplasia with synthetic grafts. In this study, hybrid small-diameter vascular grafts made of thermoplastic polyurethane (TPU) and silk fibroin, which possessed a hybrid fibrous structure of an aligned inner layer and a random outer layer, were fabricated by the electrospinning technique using a customized striated collector that generated both aligned and random fibers simultaneously. A methanol post-treatment process induced the transition of fibroin protein conformation from the water-soluble, amorphous, and less ordered structures to the water-insoluble β-sheet structures that possessed robust mechanical properties and relatively slow proteolytic degradation. The methanol post-treatment also created crimped fibers that mimicked the wavy structure of collagen fibers in natural blood vessels. Ultrafine nanofibers and nanowebs were found on the electrospun TPU/fibroin samples, which effectively increased the surface area for cell adhesion and migration. Cyclic circumferential tensile test results showed compatible mechanical properties for grafts made of a soft TPU/fibroin blend compared to human coronary arteries. In addition, cell culture tests with endothelial cells after 6 and 60 days of culture exhibited high cell viability and good biocompatibility of TPU/fibroin grafts, suggesting the potential of applying electrospun TPU/fibroin grafts in vascular tissue engineering.
Solution‐Processable Glass LiI‐Li4SnS4 Superionic Conductors for All‐Solid‐State Li‐Ion Batteries (2015)

A new, highly conductive (4.1 × 10(-4) S cm(-1) at 30 °C), highly deformable, and dry-air-stable glass 0.4LiI-0.6Li4 SnS4 is prepared using a homogeneous methanol solution. The solution process enables the wetting of any exposed surface of the active materials with highly conductive solidified electrolytes (0.4LiI-0.6Li4 SnS4), resulting in considerable improvements in the electrochemical performance of these electrodes over conventional mixture electrodes.
Menthol Increases Bendiocarb Efficacy Through Activation of Octopamine Receptors and Protein Kinase A (2019)

Great effort is put into seeking a new and effective strategies to control insect pests. One of them is to combine natural products with chemical insecticides to increase their effectiveness. In the study presented, menthol which is an essential oil component was evaluated on its ability to increase the efficiency of bendiocarb, carbamate insecticide. A multi-approach study was conducted using biochemical method (to measure acetylcholinesterase enzyme activity), electrophysiological technique (microelectrode recordings in DUM neurons in situ), and confocal microscopy (for calcium imaging). In the electrophysiological experiments, menthol caused hyperpolarization, which was blocked by an octopamine receptor antagonist (phentolamine) and an inhibitor of protein kinase A (H-89). It also raised the intracellular calcium level. The effect of bendiocarb was potentiated by menthol and this phenomenon was abolished by phentolamine and H-89 but not by protein kinase C inhibitor (bisindolylmaleimide IX). The results indicate that menthol increases carbamate insecticide efficiency by acting on octopamine receptors and triggering protein kinase A phosphorylation pathway.
Effect of seizures on developmental trajectories in children with autism (2022)

Abstract The effect of seizures in 2 to 5-year-old children with ASD was investigated in the largest and the longest observational study to-date. Parents assessed the development of 8461 children quarterly for three years on five orthogonal subscales: combinatorial receptive language, expressive language, sociability, sensory awareness, and health. Seizures were reported in 11% of children. Children with no seizures developed faster compared to matched children with seizures in all subscales. On an annualized basis, participants with no seizures improved their receptive language 1.5-times faster than those with seizures; expressive language: 1.3-times faster; sociability: 2.3-times faster; sensory awareness: 6.2-times faster; and health: 20.0-times faster. This study confirms a high prevalence of seizures in ASD children and points to the need for more systematic approach to the development of treatment strategies.
Magnetic resonance imaging of cationic compounds using their proton exchange modulating effect (2023)

Here we report a novel approach to detect non-labeled cationic compounds, named modulated saturation transfer (MOST)-MRI, based on their effect of modulating the exchange rate of surrounding exchangeable protons. MOST-MRI was able to detect polyethylenimine (PEI600, M.W. = 600 Da), at a high sensitivity (&amp;mu;M or &amp;mu;g/mL range) through its quenching effects on surrounding fast-exchanging protons. In animals, MOST-MRI detected the tumor uptake of PEI600 that was injected intratumorally at a low dose (50 &amp;mu;g/kg b.w.), indicating the potential of MOST-MRI for label-free imaging guidance that is needed for the development and clinical translation of cationic gene delivery systems.
Mapping Epitopes on a Protein Antigen by the Proteolysis of Antigen-Antibody Complexes (1986)

A monoclonal antibody bound to a protein antigen decreases the rate of proteolytic cleavage of the antigen, having the greatest effect on those regions involved in antibody contact. Thus, an epitope can be identified by the ability of the antibody to protect one region of the antigen more than others from proteolysis. By means of this approach, two distinct epitopes, both conformationally well-ordered, were characterized on horse cytochrome c.
Intelligent decision making and planning for call center (2019)

The call centers could be broadly categorized in two types: Inbound and Outbound. In an Inbound call center, the focus is always on multiple factors, such as customer satisfaction and customer retention. However, in outbound call centers, the only focus is on revenue generation by making sales and conducting successful surveys. The main challenge in all outbound call centers is to increase the revenue without increasing the expenses. The management of the call centers has used various techniques to make their Customer Service Representatives (CSRs) perfect sellers. For outbound call centers, we do not find the same level of research and systems, like the ones available for inbound call centers. Several intelligent systems have been developed for inbound call centers, which operate based on the history of their customers, maintained in their data repository. It has been observed that such systems lack a thorough analysis of the dialing data. In this paper, we use the dialing data intelligently (besides CRS's performance), after analyzing it statistically and by using different data mining techniques. We implemented the concept of 3R (Right Data to the Right CSR at the Right Time). Our work helped us to increase the number of sales (revenue) besides decreasing the expenses, by smart utilization of data and the workforce.
Tunisie - Comprendre les raisons d'un developpement socioeconomique reussi : une initiative commune d'evaluation de l'aide, realisee par la Banque Mondiale et la Banque Islamique de developpement (2005)

Tunisia has successfully shifted from resource-based exports dominated by oil and gas to manufactures and services. The economy is now driven mainly by textile, electrical, mechanical, and food processing exports; tourism and related activities; and production of olives and cereals. Real Gross Domestic Product (GDP) growth has been rising consistently, increasing from 3 percent annually over 1985-90 to more than 5 percent annually over 1996-02. Today, with a per capita income of US$2,000, Tunisians enjoy more than two-and-a-half times the real incomes that their parents had 30 years ago. Tunisia signed an association agreement with the European Union (EUAA) that provides for free trade in manufacturing by 2008. The European Union (EU) has been Tunisia's dominant trading partner; the region is the source of 67 percent of capital flows into Tunisia, accounts for a large share of Tunisia's tourism market, and is the region with the largest community of expatriate Tunisians. This dominance renders Tunisia's economy vulnerable to adverse developments in the EU.
