The samples of each composition were irradiated to 10 kGy and 100 kGy gamma dose to determine the radiation induced absorption. The Ca co-doped crystal was found to have maximum induced absorption, while B and Ba co-doped were found to be more radiation hard. The reduction in transmission could be partially restored at room temperature without any annealing treatment of the crystals. The additional absorption was also measured after annealing the crystals in reducing environment and compared with the radiation induced absorption. Thermoluminescence measurements were carried out to explain the defect structure and recovery of the transmission reduction at room temperature.
Luminosity determination in pp collisions at $\sqrt{s} = 7$ TeV using the ATLAS detector at the LHC (2011)

Abstract Measurements of luminosity obtained using the ATLAS detector during early running of the Large Hadron Collider (LHC) at $\sqrt{s} = 7$ TeV are presented. The luminosity is independently determined using several detectors and multiple algorithms, each having different acceptances, systematic uncertainties and sensitivity to background. The ratios of the luminosities obtained from these methods are monitored as a function of time and of μ , the average number of inelastic interactions per bunch crossing. Residual time- and μ -dependence between the methods is less than 2% for 0&lt; μ &lt;2.5. Absolute luminosity calibrations, performed using beam separation scans, have a common systematic uncertainty of ±11%, dominated by the measurement of the LHC beam currents. After calibration, the luminosities obtained from the different methods differ by at most ±2%. The visible cross sections measured using the beam scans are compared to predictions obtained with the PYTHIA and PHOJET event generators and the ATLAS detector simulation.
Dihalogen-bridged NHC–palladium(i) dimers: synthesis, characterisation and applications in cross-coupling reactions (2019)

A di-iodo-bridged Pd<sup>I</sup> dimer bearing an N-heterocyclic carbene ligand was made accessible via the reduction of [(IPr)PdI<sub>2</sub>]<sub>2</sub> in basic methanol solution. The structural features of [(IPr)PdI]<sub>2</sub> were explored by single-crystal X-ray analysis. It was found to be a convenient one-component precatalyst with high activity in Suzuki-Miyaura, Buchwald-Hartwig, and Sonogashira reactions.
Botnet Attack Detection Using Convolutional Neural Networks in the IoT Environment (2021)

In this study an experiment has been conducted on the detection of the most common botnet attacks in the Internet of Things (IoT) environment, using Convolutional Neural Networks (CNN) architecture. The developed CNN model was optimized by fluctuating the values of the hyperparameters at each repeating run. After the optimization process, the model was evaluated and obtained results were compared with the results in the literature. The entire dataset contains nine datasets of nine different IoT devices, each has ten types of botnet attacks. One of these datasets was used in the experiments. The proposed CNN model classified benign network traffic and botnet network traffic correctly, with a success rate (accuracy) of 97.98%. It performed better than Gaussian Naive Bayes (GNB), ANN, Support Vector Machines (SVM), and K-Nearest Neighbors (KNN) models which have success rates of 75.98%, 88.70%, 97.14%, and 97.48%, respectively.
Low multiplier coefficient sensitivity block digital filters (1984)

Block ladder filters, based upon a ladder analog, are developed. A general procedure for removing delay free loops from digital filters is presented. Using the procedure, vector delay free loops of block ladder filters are eliminated. The multiplier coefficient sensitivities of the resulting block ladder based filters are considerably better than the corresponding sensitivities of previously developed block filters.

Identification of guanine nucleotide-binding protein γ-7 as an epigenetically silenced gene in head and neck cancer by gene expression profiling (2013)

Silencing of tumor suppressor genes plays a vital role in head and neck carcinogenesis. Aberrant hypermethylation in the promoter region of some known or putative tumor suppressor genes occurs frequently during the development of various types of cancer including head and neck squamous cell carcinoma (HNSCC). In this study we used an expanded mRNA expression profiling approach followed by microarray expression analysis to identify epigenetically inactivated genes in HNSCC. Two HNSCC cell lines were treated with 5-aza-2'-deoxycytidine followed by microarray analysis to identify epigenetically silenced genes in HNSCC. We found 1,960, 614 and 427 genes were upregulated in the HNSCC cell lines JHU-012, JHU-011 and the combination of both cell lines, respectively. HNSCC tumor and normal mucosal samples were used for gene profiling by a 47K mRNA gene expression array and we found 7,140 genes were downregulated in HNSCC tumors compared to normal mucosa, as determined by microarray analysis, and were integrated with cell line data. Integrative analysis defined 126 candidate genes, of which only seven genes showed differential methylation in tumors and no methylation in normal mucosa after bisulfite sequencing. Following validation by QMSP, one gene, guanine nucleotide-binding protein γ-7 (GNG7), was confirmed to be highly methylated in tumors and unmethylated in normal mucosal and salivary rinse samples demonstrating cancer-specific methylation in HNSCC tissues. TXNIP and TUSC2 were partially methylated in tumors and normal salivary rinses but unmethylated in normal mucosa. We concluded that GNG7 is a highly specific promoter methylated gene associated with HNSCC. In addition, TXNIP and TUSC2 are also potential biomarkers for HNSCC.
Robust Multiscale Stereo Matching from Fundus Images with Radiometric Differences (2011)

A robust multiscale stereo matching algorithm is proposed to find reliable correspondences between low contrast and weakly textured retinal image pairs with radiometric differences. Existing algorithms designed to deal with piecewise planar surfaces with distinct features and Lambertian reflectance do not apply in applications such as 3D reconstruction of medical images including stereo retinal images. In this paper, robust pixel feature vectors are formulated to extract discriminative features in the presence of noise in scale space, through which the response of low-frequency mechanisms alter and interact with the response of high-frequency mechanisms. The deep structures of the scene are represented with the evolution of disparity estimates in scale space, which distributes the matching ambiguity along the scale dimension to obtain globally coherent reconstructions. The performance is verified both qualitatively by face validity and quantitatively on our collection of stereo fundus image sets with ground truth, which have been made publicly available as an extension of standard test images for performance evaluation.
Abstract 3468: Immunoproteasome expression and checkpoint blockade response in advanced non-small cell lung cancer (2023)

Abstract Responders to checkpoint blockade in Non Small Cell Lung Cancer (NSCLC) often feature an inflamed microenvironment prior to therapy. However, the complete set of molecular drivers connecting this histologic observation to enhanced tumor clearance remain enigmatic. In updated analysis of the Stand Up 2 Cancer-Mark Foundation (SU2C-MARK) Cohort - a collection of 393 patients with whole exome and/or RNA sequencing along with matched checkpoint blockade response annotation - we identify a prominent predictive role for inducible components of the immunoproteasome, a non-canonical peptide processing complex upstream of antigen presentation. Notably, these subunits are enriched as predictors relative to interferon-inducible genes as well as proteasome components in general, and are consistently associated with objective response, progression-free survival and overall survival. Expression of Immunoproteasome subunits associates positively with TCR (but not BCR) burden, supporting a mechanistic model in which enhanced immunoproteasome processivity leads to superior T-cell recognition. Furthermore, although they are known to be targets of interferon gamma (IFNɣ), we demonstrate that their expression is better modeled via a combination of IFNɣ and tumor necrosis factor-α (TNFα) levels, suggesting they may act as integrators of multiple cytokine cascades. Given the fact that the immunoproteasome can alter both antigen quantity as well as quality (including peptide cleavage site preference), the enhanced expression of this complex in the setting of checkpoint blockade response may have important implications for modeling of antigen presentation. These data also suggest novel strategies to enhance immune checkpoint blockade.

Reentry Site During Fibrillation Induction in Relation to Defibrillation Efficacy for Different Shock Waveforms (2001)

The defibrillation waveforms with the lowest DFTs were those that induced reentry at sites of low shock potential gradient, indicating efficacious stimulation of myocardium. Additionally, the site of reentry induced by waveforms with the lowest DFTs was in myocardium that was more highly recovered just before the shock, perhaps because this high degree of recovery seldom occurs during defibrillation due to the rapid activation rate during fibrillation.
Isolated Preset Architecture for a 32nm SOI embedded DRAM macro (2012)

The Isolated Preset Architecture (IPA) improves retention characteristics by implementing a weak read `1' Isolation scheme, allowing a lower stored `1' level to be sensed. The architecture also reduces sub-array area by 15% and bit-line activation power by 2× compared to previous design, without impacting performance. The architecture was implemented in IBM's 32nm High-K/Metal SOI embedded DRAM technology. Hardware results confirm 1.8ns random cycle and 2× improved retention characteristic with optimized Analog reference tuning.
Macroscopic and high-throughput printing of aligned nanostructured polymer semiconductors for MHz large-area electronics (2015)

High-mobility semiconducting polymers offer the opportunity to develop flexible and large-area electronics for several applications, including wearable, portable and distributed sensors, monitoring and actuating devices. An enabler of this technology is a scalable printing process achieving uniform electrical performances over large area. As opposed to the deposition of highly crystalline films, orientational alignment of polymer chains, albeit commonly achieved by non-scalable/slow bulk alignment schemes, is a more robust approach towards large-area electronics. By combining pre-aggregating solvents for formulating the semiconductor and by adopting a room temperature wired bar-coating technique, here we demonstrate the fast deposition of submonolayers and nanostructured films of a model electron-transporting polymer. Our approach enables directional self-assembling of polymer chains exhibiting large transport anisotropy and a mobility up to 6.4 cm(2) V(-1) s(-1), allowing very simple device architectures to operate at 3.3 MHz. Thus, the proposed deposition strategy is exceptionally promising for mass manufacturing of high-performance polymer circuits.
Rotational Motion of Cytochrome c Derivatives Bound to Membranes Measured by Fluorescence and Phosphorescence Anisotropy (1982)

Molecular motion of metal-free and metal-substituted cytochrome c derivatives was examined using the anisotropy of emissions from the singlet and the triplet states. The anisotropy of fluorescence provides a means to study the motion of cytochrome c in the nanosecond time scale, since the fluorescence lifetime of metal-free cytochrome c is around 10 ns. We find that the anisotropy of fluorescence of metal-free cytochrome c when bound to mitochondria does not decay, but when bound to phospholipids has a small component which decays independently of the rotation of the whole molecule. The use of phosphorescence extends the time scale for study into the millisecond regime, since the lifetime of the excited triplet state of zinc cytochrome c, as measured by triplet-triplet absorption and phosphorescence emission is approximately equal to 9 ms for free zinc cytochrome c and 7 ms for mitochondrial membrane-bound zinc cytochrome c at room temperature. The decay of anisotropy of phosphorescence emission of mitochondrial membrane-bound zinc cytochrome c is clearly biphasic; the fast component corresponds to a rotational relaxation time of 300 mus and the slow component with relaxation time of approximately equal to 6 ms. The slow component appears to be due to the rotation of the entire mitochondrion, whereas the fast component was interpreted to be due to the rotation of cytochrome c in a cone about a single axis perpendicular to the plane of the membrane surface.
APPLICATION OF MARKOV CHAIN MODELS FOR SHORT-TERM GENERATION ASSETS VALUATION (2005)

This paper valuates generation assets within deregulated electricity markets. A new framework for modeling electricity markets with a Markov chain model is proposed. The Markov chain model captures the fundamental economic forces underlying the electricity markets such as demand on electricity and supplied online generation capacity. Based on this new model, a real option analysis is adopted to valuate generation assets. The Markov chain model is combined with a binomial tree to approximate the stochastic movement of prices on both electric energy and ancillary services, which are driven by the market forces. A detailed example is presented. This method is shown to provide optimal operation policies and market values of generation assets. This method also provides means to analyze the impacts of demand growth patterns, competition strategies of competitors, and other key economic forces.

A collaborative approach for local training on contemporary mobile technologies in Eritrea (2017)

The unprecedented uptake of mobile services in Africa has had substantial direct and indirect impacts on the local economies. Eritrea is one of the countries in the continent that is relatively late adaptor of mobile broadband technologies. This change in the local mobile landscape is creating an urgent need for enhanced local expertise in mobile technologies. To that end, the local higher education institutions play a key role in the capacity building process. In this article, we describe the experience from a capacity building project with the Eritrean Institute of Technology (EIT) that resulted in the implementation training course on Advanced Wireless Technologies (AWT) at EIT. We demonstrate how the course design was fit with the local context and training needs within the mobile ecosystem. Furthermore, we present the teaching approach and hands-on learning activities that were utilized in the AWT course. Finally, we provide some concluding discussions based on the experiences from venue of the course implementation. The collaborative approaches and experiences shared here provide a useful model for local HEIs in Eritrea (and Africa in general) that are undergoing similar process of adapting advanced mobile technologies.

Bovine ocular squamous cell carcinoma: tumor-associated immunity detected by E-rosette augmentation test. (1983)

The E-rosette augmentation (ERA) assay was used to study cell-mediated immunity with blood leukocytes from cattle with bovine ocular squamous cell carcinoma (BOSCC), from cattle with benign ocular or cutaneous lesions, and from healthy controls. Potassium chloride extracts (3 M) of BOSCC and skin from the same donor, cutaneous bovine papillomas, allogeneic lymphosarcoma, and xenogeneic sheep squamous cell carcinoma were used as antigens. Of the 21 animals with BOSCC, leukocytes of 19 gave positive ERA reactions to BOSCC extract and only those of 4 reacted nonspecifically to other extracts. Of 21 animals in the control group, only 3 gave positive ERA reactions. In reciprocal tests, cattle with BOSCC showed ERA reactivity only against extracts of BOSCC, and cattle with cutaneous papillomas showed reactivity only against extracts of cutaneous papillomas. Blood leukocytes from tumor-bearing cattle stimulated with related tumor extracts released a soluble factor that enhanced E-rosette formation when tested on normal bovine leukocytes.

Evaluation of the Dietary Supplementation of a Formulation Containing Ascorbic Acid and a Solid Dispersion of Curcumin with Boric Acid against Salmonella Enteritidis and Necrotic Enteritis in Broiler Chickens (2019)

Two experiments were conducted to evaluate the effect of the prophylactic or therapeutic administration of a 0.1% mixture containing ascorbic acid and a solid dispersion of curcumin with polyvinylpyrrolidone and boric acid (AA-CUR/PVP-BA) against <i>Salmonella</i> Enteritidis (<i>S</i>. Enteritidis) in broiler chickens. A third experiment was conducted to evaluate the impact of the dietary administration of 0.1% AA-CUR/PVP-BA in a necrotic enteritis (NE) model in broiler chickens. The prophylactic administration of 0.1% AA-CUR/PVP-BA significantly decreased <i>S</i>. Enteritidis colonization in cecal tonsils (CT) when compared to the positive control group (PC, <i>p</i> < 0.05). The therapeutic administration of 0.1% AA-CUR/PVP-BA significantly reduced the concentration of <i>S</i>. Enteritidis by 2.05 and 2.71 log in crop and CT, respectively, when compared with the PC on day 10 post-<i>S</i>. Enteritidis challenge. Furthermore, the serum FITC-d concentration and total intestinal IgA levels were also significantly lower in chickens that received 0.1% AA-CUR/PVP-BA. Contrary, the PC group showed significantly higher total intestinal IgA levels compared to the negative control or AA-CUR/PVP-BA groups in the NE model. However, 0.1% AA-CUR/PVP-BA showed a better effect in reducing the concentration of <i>S</i>. Enteritidis when compared to the NE model. Further studies with higher concentration of AA-CUR/PVP-BA into the feed to extend these preliminary results are currently being evaluated.

Highly Diastereo- and Enantioselective CuH-Catalyzed Synthesis of 2,3-Disubstituted Indolines (2015)

A diastereo- and enantioselective CuH-catalyzed method for the preparation of highly functionalized indolines is reported. The mild reaction conditions and high degree of functional group compatibility as demonstrated with substrates bearing heterocycles, olefins, and substituted aromatic groups, renders this technique highly valuable for the synthesis of a variety of cis-2,3-disubstituted indolines in high yield and enantioeselectivity.
