Crystalline GaSb-core optical fibers with room-temperature photoluminescence (2018)

Glass-clad, GaSb-core fibers were drawn and subsequently laser annealed. The as-drawn fibers were found to be polycrystalline, possess Sb inclusions, and have oxide contamination concentrations of less than 3 at%. Melting and resolidifying regions in the cores using 10.6 µm CO2 laser radiation yielded single crystalline zones with enhanced photoluminescence (PL), including the first observation of strong room temperature PL from a crystalline core fiber. Annealed fibers show low values of tensile strain and a bandgap close to that of bulk GaSb.
Prognostic value of perfusion CT in hepatocellular carcinoma treatment with sorafenib: comparison with mRECIST in longitudinal follow-up (2017)

Background Targeted therapies are of increasing clinical importance and classic radiologic therapy response-criteria often fail to detect early therapeutic response or failure. For hepatocellular carcinoma (HCC), this is of major importance as therapeutic options are limited. Purpose To investigate the impact of sorafenib-treatment on intralesional perfusion using perfusion computed tomography (PCT) in HCC and to correlate the observed changes with mRECIST and the course of serum alpha-fetoprotein (AFP) for identification of their prognostic value. Material and Methods PCT was performed before and after two months of sorafenib treatment in 28 consecutive HCC patients and AFP levels were registered. Changes in tumor perfusion parameters blood flow (BF), blood volume (BV), mean transit time (MTT), volume transfer constant (K<sup>trans</sup>), arterial liver perfusion (ALP), and hepatic perfusion index (HPI) were registered in one target lesion. mRECIST measurements were performed at baseline and after two and four months during sorafenib treatment. Results According to mRECIST, after two months of treatment, all patients showed stable disease (SD), whereas after four months, 13 patients (46%) showed SD and 15 patients (54%) showed progressive disease (PD). A significant decrease was found in perfusion parameters BF, BV, K<sup>trans</sup>, ALP, and HPI in patients with SD as well as a significant increase in MTT ( P < 0.05) after two months compared to baseline, while patients with PD showed a significant increase in HPI, BF, and BV. There were no correlations between AFP and mRECIST or perfusion parameters. Conclusion Decreased intralesional BF and HPI after two months of sorafenib treatment predicts disease stabilization after four months, whereas AFP dynamics were of limited value.
Tolerance of Selected Advanced Cowpea (Vigna unguiculata) Breeding Lines to Fomesafen (2007)

Chemical options for weed control in commercial cowpea production are limited. Repeated long-term use of the acetolactate synthase (ALS) inhibitor, imazethapyr, has resulted in selection for ALS-resistant populations of Palmer amaranth. Experiments were conducted at Bixby, OK, and Kibler, AR, from 2001 to 2003 to evaluate the tolerance of cowpea cultivars and advanced breeding lines to fomesafen, a potential alternative for controlling ALS-resistant Palmer amaranth and other problematic broadleaf weeds. Eight commercial cultivars and 42 advanced breeding lines were entered in the preliminary screening, using 0.84 kg/ha fomesafen. Six breeding lines were selected for the first replicated trial and three (00-582, 00-584, and 00-609) were advanced to across-location experiments. Fomesafen doses of 0, 0.17, 0.34, and 0.67 kg/ha were tested across locations. ‘Early Scarlet’ was used as commercial standard. The advanced lines had equal or higher yield potential (1,182 to 1,936 kg/ha) than Early Scarlet (1,108 kg/ha) across locations. Of the cultivars tested, line 00-609 was the best yielder, whereas 00-584 had the highest tolerance to fomesafen. At the commercial fomesafen rate of 0.34 kg/ha, 00-584 had higher yield (974 and 1,735 kg/ha, respectively, at Bixby, OK, and Kibler, AR) than the nontreated, weed-free, Early Scarlet. Thus, fomesafen can be used on the tolerant line, 00-584, without reducing yield potential relative to Early Scarlet.
Virtual wireless network urbanization (2011)

Adapting virtualization concepts to satisfy many of today's network telecommunication challenges receives more and more attention. We have developed virtual environment design to allow the coexistence of virtual networks and their respective operators. In our approach, virtualized wireless access equipment are deployed to provide users more flexibility to access their services delivered by the allocated virtual networks. In this paper, we describe how we improved virtual network urbanization by including virtualized access point equipment. We developed this approach for supporting wireless network advantages such as mobility, coverage areas, installation speed and simplicity. The relevant results of the deployment are exposed.
High prevalence of hepatitis C in Egyptian patients with chronic liver disease. (1995)

The highest prevalence rates of hepatitis C virus infection in the world have been recently reported among Egyptian blood donors and frequent recipients of transfusions and other blood products. This is the first report, however, demonstrating hepatitis C as the most frequent association with chronic liver disease in Egypt. Of 1023 patients referred to the Liver Institute in Menoufia governorate for evaluation of chronic liver disease, 752 (73.5%) had antibodies to hepatitis C compared with 168 (16.4%) with hepatitis B surface antigen. Hepatitis C antibody was more common in patients with active schistosomiasis and patients without hepatitis B surface antigenaemia. Of 100 patients having liver biopsies, histological findings consistent with chronic viral hepatitis or its complications were found in 89 and antibody to hepatitis C was present in 75 (84.3%) of these patients with chronic hepatitis, active cirrhosis or hepatocellular carcinoma. These data pointing to the importance of hepatitis C as a cause of chronic liver disease in Egypt emphasise the necessity of studies delineating its routes of transmission in this country.
Thieves Like Us (2018)

In Steve McQueen’s Widows, a Chicago-set update of Lynda La Plante’s 1980s series about a group of women planning a heist, he portrays the entire social system as rotten, showing how political corruption intersects with street criminality, as well as with the church, police and ﬁnance.
Is overreaction/underreaction chosen by managers Evidence from Greece (2021)

This paper models overreaction/underreaction as being the outcome of company managers' choices to manipulate earnings in response to perceived mispricing of their company. One of the more prominent attempts to reconcile observed short-term overreaction and consequent secular underreaction to earnings news interprets earnings announcements as 'selective' events. In financial markets events are 'selected' when contrived in response to perceived asset mispricing. We interpret earnings management by managers as a process requiring a selection of earnings in response to perceived mispricing of their corporation's stock. Post-earnings announcement drift is then interpreted as one consequence of this form of managerial choice. We devise and test a trading strategy, implemented at the earnings announcement date, based on the level of discretionary accruals in relation to past mispricing. The profitability of such a strategy is tested and conclusions for attempts to reconcile short-term overreaction with secular underreaction are drawn.

Correlation between H-ras p21TLeu61 protein content and tumorigenicity of NIH3T3 cells. (1988)

We have prepared a number of NIH3T3 clonal cell lines that contain an H-ras transforming gene with an A----T transversion at the 61st codon. The clonal lines contain 1 to 3 cell equivalents of the transforming oncogene and some lines look more morphologically transformed than others. Using Y13-238, a rat monoclonal antibody that recognizes H-ras p21 but not Ki- or N-ras in rodent cells, we found that the degree of morphological change is correlated with the relative amount of transforming protein in the selected clonal lines. Nude mice were injected with cells from lines containing different amounts of the transforming protein, ranging from approximately 1 to 10 times the level of normal H-ras protein present in NIH3T3 cells. Tumors arose in all mice that received cells containing the transforming protein. Their time of appearance (tumor latency) was correlated with the number of cells injected and the amount of transforming protein present in each clonal line; however, the subsequent rate of growth and ultimate size of the tumors were similar. Thus, it appears that the transforming protein has a significant effect on some early step in tumor development. Our results also show that relatively low amounts of transforming ras protein are sufficient to cause tumorigenicity in NIH3T3 cells and that higher amounts of the transforming protein cause proportionately faster responses.
Recoverable energy and small antennas (2017)

The maximum “recoverable” energy of a small radiator is determined. This energy is defined as the maximum energy that can be recovered from the electromagnetic field distribution in entire space generated by the radiator up to the time point considered. It is shown that the concept of recoverable energy for small radiators leads to a quasi-constant future current. It is also shown that this “recoverable” energy can be identified with the stored energy for a small radiator.
Molecular Dynamics Simulations of Bromodomains Reveal Binding‐Site Flexibility and Multiple Binding Modes of the Natural Ligand Acetyl‐Lysine (2014)

Abstract Experimental protein structures provide spatial information at the atomic level. A further dimension, time, is supplemented by molecular dynamics. Since the pioneering work on the 58‐residue inhibitor of bovine pancreatic trypsin in the group of Martin Karplus in the seventies, molecular dynamics simulations have shown that the intrinsic flexibility of proteins is essential for their function. Here, we review simulation studies of bromodomains. These protein modules are involved in the recognition of acetylated lysine side chains, a post‐translational modification frequently observed in histone tails. The molecular dynamics simulations have unmasked: (i) the large plasticity of the loops lining the acetyl‐lysine binding site (coupled to its self‐occlusion), and (ii) multiple binding modes of acetyl‐lysine. These simulation results suggest that recognition of histone tails by bromodomains is modulated by their intrinsic flexibility, and further corroborate the utility of molecular dynamics in understanding (macro)molecular recognition.
Facteurs d'échelle phénoménologiques pour la transition critique liquide-gaz des fluides purs (1985)

Study of Memristive Associative Capacitive Networks for CAM Applications (2015)

Resistively switching devices are key enabler for future hybrid CMOS/nano-crossbar array architectures. Due to the availability of nonvolatile states novel reconfigurable in-memory computing approaches become feasible. In particular complementary resistive switches are highly attractive cross-point junction elements due to their inherent sneak path prevention. By applying a nondestructive capacitive readout procedure the complementary resistive switches implement reconfigurable associative capacitive networks. Those networks establish the functionality of content addressable memories and enable memory intensive computing operations for realization of pattern recognition tasks. These are essential for router or network switch applications. In this study a highly accurate physics-based dynamical memristive device model is used to evaluate the network properties for various configurations. The high ON-to-OFF ratio of electrochemical metallization cells beneficially supports the functionality of the network. The voltage margin and energy consumption are analyzed for various crossbar array sizes. Moreover, a test setup to study those networks supported by measurements was developed and proof-of-concept results for a pre-programmed capacitive array are presented.
An osteogenic bioink composed of alginate, cellulose nanofibrils, and polydopamine nanoparticles for 3D bioprinting and bone tissue engineering (2022)

Bioprinting is an emerging technology for manufacturing cell-laden three-dimensional (3D) scaffolds, which are used to fabricate complex 3D constructs and provide specific microenvironments for supporting cell growth and differentiation. The development of bioinks with appropriate printability and specific bioactivities is crucial for bioprinting and tissue engineering applications, including bone tissue regeneration. Therefore, to produce functional bioinks for osteoblast printing and bone tissue formation, we formulated various nanocomposite hydrogel-based bioinks using natural and biocompatible biomaterials (i.e., alginate, tempo-oxidized cellulose nanofibrils (TOCNF), and polydopamine nanoparticles (PDANPs)). Rheological studies and printability tests revealed that bioinks containing 1.5% alginate and 1.5% TOCNF in the presence or absence of PDANP (0.5%) are suitable for 3D printing. Furthermore, in vitro studies of 3D-printed osteoblast-laden scaffolds indicated that the 0.5% PDANP-incorporated bioink induced significant osteogenesis. Overall, the bioink consisting of alginate, TOCNF, and PDANPs exhibited excellent printability and bioactivity (i.e., osteogenesis).
EduSense (2019)

Providing university teachers with high-quality opportunities for professional development cannot happen without data about the classroom environment. Currently, the most effective mechanism is for an expert to observe one or more lectures and provide personalized formative feedback to the instructor. Of course, this is expensive and unscalable, and perhaps most critically, precludes a continuous learning feedback loop for the instructor. In this paper, we present the culmination of two years of research and development on EduSense, a comprehensive sensing system that produces a plethora of theoretically-motivated visual and audio features correlated with effective instruction, which could feed professional development tools in much the same way as a Fitbit sensor reports step count to an end user app. Although previous systems have demonstrated some of our features in isolation, EduSense is the first to unify them into a cohesive, real-time, in-the-wild evaluated, and practically-deployable system. Our two studies quantify where contemporary machine learning techniques are robust, and where they fall short, illuminating where future work remains to bring the vision of automated classroom analytics to reality.

Heterobimetallic complexes of IrM (M = FeII, CoII, and NiII) core and bridging 2-(diphenylphosphino)pyridine: electronic structure and electrochemical behavior (2020)

Three complexes based on an Ir-M (M = Fe<sup>II</sup>, Co<sup>II</sup>, and Ni<sup>II</sup>) heterobimetallic core and 2-(diphenylphosphino)pyridine (Ph<sub>2</sub>PPy) ligand were synthesized via the reaction of trans-[IrCl(CO)(Ph<sub>2</sub>PPy)<sub>2</sub>] and the corresponding metal chloride. Their structures were established by single-crystal X-ray diffraction as [Ir(CO)(μ-Cl)(μ-Ph<sub>2</sub>PPy)<sub>2</sub>FeCl<sub>2</sub>]·2CH<sub>2</sub>Cl<sub>2</sub> (2), [IrCl(CO)(μ-Ph<sub>2</sub>PPy)<sub>2</sub>CoCl<sub>2</sub>]·2CH<sub>2</sub>Cl<sub>2</sub> (3), and [Ir(CO)(μ-Cl)(μ-Ph<sub>2</sub>PPy)<sub>2</sub>NiCl<sub>2</sub>]·2CH<sub>2</sub>Cl<sub>2</sub> (4). Time-dependent DFT computations suggest a donor-acceptor interaction between a filled 5d<sub>z<sup>2</sup></sub> orbital on iridium and an empty orbital on the first-row metal atom, which is supported by UV-vis studies. Magnetic moment measurements show that the first-row metals are in their high-spin electronic configurations. Cyclic voltammetry data show that all the complexes undergo irreversible decomposition upon either reduction or oxidation. Reduction of 4 proceeds through an ECE mechanism. While these complexes are not stable to electrocatalysis conditions, the data presented here refine our understanding of the bonding synergies of the first-row and third-row metals.
High-Precision Calibration Approaches to Robot Vision Systems (2010)

Motivated by the practical issues in applying the vision systems to the industrial robot vision applications, the dissertation has made great efforts on camera calibration, camera recalibration, vision systems calibration and pose estimation.

Firstly, the calibration methods from Tsai are analyzed and improved by solving the degenerate and extent situations. Since the image origin is not calibrated in Tsai methods, the direct linear method and the calibration with vanishing points are referred. Theycalibrate the image origin but neglect the lens distortion. The situation in practice is that the lens distortion is more sensitive than the image origin to pose estimation and
it is difficult to give an initial guess to implement the distortion alignment. Therefore, a direct search algorithm for the image origin is introduced by use of the other camera parameters. Finally, the refinement with nonlinear minimization for all camera parameters comes into the discussing sight.

After the settle down of the mathematical issues in camera calibration, some approaches to online calibration are proposed according to the application environments. The calibration with a robot tool and with a calibration body are the alternative solutions for the robot vision applications. Taking further the application procedure into account, an approach to camera pose calibration with an external measurement system is introduced. 

When the applications in industries are given more concerns, the camera recalibration needs to be considered. Since the camera is disturbed by its pose in most of cases, the recalibration is simplified to determine the changes happened to the camera pose. Three recalibration approaches are proposed for checking the changes and determining the corrections of the camera pose in real time.

Eventually, some contributions on vision systems calibration and pose estimation are made according to the applications. Although the application with a mono-camera system and the calibration to a stereo sensor are discussed in details, the dominating target is the multi-camera system. Some valuable approaches, including pattern weight,zero measurement, pattern compensation and security control, to improve the system performances in industrial applications are therefore brought forward.

All the methods and approaches referred in the issertation aim at applying the vision systems accurately and efficiently to the robot vision applications. They relate
fruitfully the techniques in laboratory to the industrial applications.
Synthesis, Antibacterial and Thermal Studies of Cellulose Nanocrystal Stabilized ZnO-Ag Heterostructure Nanoparticles (2013)

Synthesis of ZnO-Ag heterostructure nanoparticles was carried out by a precipitation method with cellulose nanocrystals (CNCs) as a stabilizer for antimicrobial and thermal studies. ZnO-Ag nanoparticles were obtained from various weight percentages of added AgNO₃ relative to Zn precursors for evaluating the best composition with enhanced functional properties. The ZnO-Ag/CNCs samples were characterized systematically by TEM, XRD, UV, TGA and DTG. From the TEM studies we observed that ZnO-Ag heterostructure nanoparticles have spherical shapes with size diameters in a 9-35 nm range. The antibacterial activities of samples were assessed against the bacterial species Salmonella choleraesuis and Staphylococcus aureus. The CNC-stabilized ZnO-Ag exhibited greater bactericidal activity compared to cellulose-free ZnO-Ag heterostructure nanoparticles of the same particle size. The incorporation of ZnO-Ag hetreostructure nanoparticles significantly increased the thermal stability of cellulose nanocrystals.
AFAP-110 is overexpressed in prostate cancer and contributes to tumorigenic growth by regulating focal contacts (2007)

The actin filament-associated protein AFAP-110 is an actin cross-linking protein first identified as a substrate of the viral oncogene v-Src. AFAP-110 regulates actin cytoskeleton integrity but also functions as an adaptor protein that affects crosstalk between Src and PKC. Here we investigated the roles of AFAP-110 in the tumorigenic process of prostate carcinoma. Using immunohistochemistry of human tissue arrays, we found that AFAP-110 was absent or expressed at very low levels in normal prostatic epithelium and benign prostatic hyperplasia but significantly increased in prostate carcinomas. The level of AFAP-110 in carcinomas correlated with the Gleason scores. Downregulation of AFAP-110 in PC3 prostate cancer cells inhibited cell proliferation in vitro and tumorigenicity and growth in orthotopic nude mouse models. Furthermore, downmodulation of AFAP-110 resulted in decreased cell-matrix adhesion and cell migration, defective focal adhesions, and reduced integrin beta1 expression. Reintroduction of avian AFAP-110 or a mutant disabling its interaction with Src restored these properties. However, expression of an AFAP-110 lacking the PKC-interacting domain failed to restore properties of parental cells. Thus, increased expression of AFAP-110 is associated with progressive stages of prostate cancer and is critical for tumorigenic growth, in part by regulating focal contacts in a PKC-dependent mechanism.
The chemistry and catalytic properties of ruthenium and osmium complexes. Part 1. Homogeneous catalysis of organic reactions by bromo(carbonyl)hydridotris(triphenylphosphine)osmium(II) (1985)

The title compound catalyses CC bond migration, isomerisation of allyl alcohol, hydrogenation of ayclic and cyclic olefins, dienes, acetylenes, aldehydes, ketones, α,β-unsaturated aldehydes and ketones, and hydroformylation of alkenes under moderate reaction conditions. High selectivities have been observed in the hydrogenation of conjugated and unconjugated dienes to monoenes, CC to CC bonds, α,β-unsaturated aldehydes to unsaturated alcohols, and α,β-unsaturated ketones to saturated ketones; L-carvone [2-methyl-5-(1-methylethenyl)cyclohex-2-en-1-one] may be selectively reduced to 2-methyl-5-(1-methylethyl)cyclohex-2-en-1-one or 2-methyl-5-(1-methylethyl)cyclohexanone depending on the reaction conditions.
