Effect of pressure on the electrical properties of flexible NiPc thin films fabricated by rubbing-in technology (2020)

Nickel phthalocyanine (NiPc) film was deposited onto the surface of flexible conductive glass by rubbing-in technology and used to fabricate devices based on ITO/NiPc/CNT/rubber structure. The I – V characteristics of the devices were investigated under different uniaxial pressures of 200, 280, and 480 gf/cm 2 , applied perpendicular to the surface of the NiPc film. Results showed that the nonlinearity coefficients of the I – V curves are in the range of 2 to 3, which was found to be decreased with the increase of the pressure. The rectification ratio of the devices was estimated to be varied from 1.5 to 3 based on the applied pressure. Concluding, the resistance of the active layers was decreased with the increase of both pressure and voltage. We believe that using the rubbing-in technology under sufficient applied pressure it is possible to utilize NiPc for the development of various electronic devices such as diodes, nonlinear resistors, and sensors.

Severe fludarabine neurotoxicity after reduced intensity conditioning regimen to allogeneic hematopoietic stem cell transplantation: a case report (2015)

We present a case of severe, irreversible neurotoxicity in a 55-year-old-patient with myelofibrosis undergoing hematopoietic stem cell transplantation following a reduced intensity conditioning including fludarabine. The patient developed progressive sensory-motor, visual and consciousness disturbances, eventually leading to death. MRI imaging pattern was unique and attributable to fludarabine neurotoxicity.
Vinegar and its active component acetic acid inhibit SARS-CoV-2 infection in vitro and ex vivo (2021)

Interferon; ACE2: Angiotensin converting enzyme 2. Vero cells were seeded at 2.5×10 5 cell/well in 24-well plates in Eagle's minimum essential medium (EMEM) supplemented with 10% fetal calf serum (complete medium).Twenty-four h later, 50 plaque forming units (PFU) of a previously titrated SARS-CoV-2 isolate (GISAID accession ID: EPI_ISL_413489) were added to vinegar (from 0.28% to 0.008%) or acetic acid (from 0.1 to 0.5%) serially diluted (1:2) in PBS and incubated for 15 min at either 37°C or 45°C before addition to confluent Vero cells.
Self-Reconfiguration in Response to Faults in Modular Aerial Systems (2020)

We present a self-reconfiguration technique by which a modular Hying platform can mitigate the impact of rotor failures. In this technique, the system adapts its configuration in response to rotor failures to be able to continue its mission while efficiently utilizing resources. A mixed integer linear program determines an optimal module-to-position allocation in the structure based on rotor faults and desired trajectories. We further propose anefficient dynamic programming algorithm that minimizes the number of disassembly and reassembly steps needed for reconfiguration. Evaluation results show that our technique can substantially increase the robustness of the system while utilizing resources efficiently, and that it can scale well with the number of modules.
Protective Effects of Luteolin on Diabetic Nephropathy in STZ‐Induced Diabetic Rats (2011)

Diabetic nephropathy is a long-term complication of diabetic mellitus. Many experimental evidences suggest that persistent hyperglycaemia generates intracellular reactive oxygen species (ROS) and upregulates transforming growth factor-b1 and extracellular matrix expression in mesangial and tubular epithelial cells, which is involved of free radicals in the pathogenesis of diabetes and more importantly in the development of diabetic complications. Antioxidants effectively inhibit high-glucose- and H2O2-induced transforming growth factor-b1 and fibronectin upregulation, thus providing evidence that ROS play an important role in high glucose-induced renal injury. The flavonoid luteolin has been shown to possess direct antioxidant activity, therefore we hypothesize that it may be useful in treatment of many chronic disease associated with oxidative stress, such as diabetic nephropathy via its antioxidant properties. Our results suggested that protection against development of diabetic nephropathy by luteolin treatment involved changes in superoxide dismutase (SOD) activity, the malondialdehyde (MDA) content and expression of Heme Oxygenase-1 (HO-1) protein.
Strategies for Business Process Reengineering: Evidence from Field Studies (1995)

:This paper reports on early results from case study research into the relationship between business process reengineering (BPR) and strategic planning. First a framework for analysis is proposed based on the concept of alignment. This “process alignment model” comprises four lenses of enquiry: process, strategy, information systems, and change management and control. Four case studies are then described, selected from a wider sample to demonstrate variation across the four domains. A taxonomy of strategies for BPR is derived from the case studies. This taxonomy suggests a richer variety of BPR practice than has been documented to date and provides an opportunity and platform for further research.

Noncoupled NADH:Ubiquinone Oxidoreductase of <i>Azotobacter vinelandii</i> Is Required for Diazotrophic Growth at High Oxygen Concentrations (2001)

The gene encoding the noncoupled NADH:ubiquinone oxidoreductase (NDH II) from Azotobacter vinelandii was cloned, sequenced, and used to construct an NDH II-deficient mutant strain. Compared to the wild type, this strain showed a marked decrease in respiratory activity. It was unable to grow diazotrophically at high aeration, while it was fully capable of growth at low aeration or in the presence of NH(4)(+). This result suggests that the role of NDH II is as a vital component of the respiratory protection mechanism of the nitrogenase complex in A. vinelandii. It was also found that the oxidation of NADPH in the A. vinelandii respiratory chain is catalyzed solely by NDH II.
MIC of Nuclear Waste Containers (2008)

Abstract Microbiologically influenced corrosion (MIC) is one of a number of threats to the long-term integrity of nuclear waste containers. As such, the potential for, and extent of, MIC must be assessed and suitable models developed for predicting the long-term behaviour of the container. There are two broad approaches to assessing the threat posed by MIC; first, to determine whether the environment will support microbial activity and, if so, where and when it will occur, and second, to estimate the maximum amount of damage that could occur if microbial activity in the repository is possible. A decision-tree approach is used to present evidence for both of these approaches and to decide whether MIC is a significant threat to the integrity of the container. Examples are provided from various international nuclear waste management programs. Microbial effects will not compromise the safety of the overall disposal system because they will not lead to either early container failures or to a large number of simultaneous failures, both factors which can lead to an increase in the peak dose.
Coplanar waveguide fed ultra-wideband antenna over the planar and cylindrical surfaces (2014)

The investigation of coplanar waveguide fed ultra-wideband antenna and the influence of the proximity of different materials on the reflection coefficients and radiation characteristics is presented. The antenna is composed of two circular coplanar strips which enclose slot aperture of similar shape and is designed on a thin and flexible substrate. From the modeling and experimental tests the antenna shows good performance in 2-15GHz frequency range with return losses better than 10dB. It is shown that the proximity of different, non-metalic materials does not significantly affect antenna performance. The proximity of metalic screens deteriorates its radiation pattern and reflection coefficient. However with the correct choice of the distance between screen and antenna the required level of return losses can be provided.
United Snakes [image analysis software] (1999)

Since their debut in 1987, snakes (active contour models) have become a standard image analysis technique with several variants now in common use. We present a portable, reusable software package called "United Snakes". The package unites the most popular snake variants, including finite difference, B-spline, and Hermite polynomial snakes within the mathematical framework of a general finite element formulation with a choice of shape functions. The package furthermore incorporates a recently proposed snake-like technique known as "livewire". We integrate snakes and livewire by introducing an effective method for imposing hard constraints on snakes. Our experiments demonstrate that snakes and livewire have complementary strengths and that their union offers a more powerful tool for interactive image analysis, especially for medical imaging applications. United Snakes is implemented in Java as a JavaBean so that it can easily be integrated in end user application systems.

All-Pairs Common-Ancestor Problems in Weighted Dags (2006)

This work considers (lowest) ancestor problem in weighted \\directed acyclic graphs. \\The minimum-weight (lowest) ancestor two vertices is vertex among set (lowest) with the smallest ancestral distance. all-pairs minimum-weight common ancestor problem we present an O(nm) algorithm for arbitrary edge which is optimal for sparse graphs and an O(n^2.575) algorithm for dense graphs with moderately bounded edge weights based on matrix multiplication. The presented solutions to all-pairs minimum-weight lowest common ancestor problem are based upon solutions all-pairs all lowest common problem in unweighted graphs, which represents an upper bound. For all-pairs all lowest problem we give an O(nm k^2) algorithm, with k bound on maximum number lowest ancestors for pairs, and an O(nm width(G)) algorithm, where width(G) is size of largest antichain (independent set) in transitive closure G. \\The ideas are applicable for fast matrix multiplication implying an O(n^3.616) algorithm.
Gut Microbiota Composition Is Related to Cardiorespiratory Fitness in Healthy Young Adults (2018)

Bacteria residing in the human gastrointestinal tract has a symbiotic relationship with its host. Animal models have demonstrated a relationship between exercise and gut microbiota composition. This was the first study to explore the relationship between cardiorespiratory fitness (maximal oxygen consumption, VO<sub>2</sub>max) and relative gut microbiota composition (Firmicutes to Bacteroidetes ratio [F/B]) in healthy young adults in a free-living environment. Twenty males and 17 females (25.7 ± 2.2 years), who did not take antibiotics in the last 6 months, volunteered for this study. VO<sub>2</sub>max was measured using a symptom-limited graded treadmill test. Relative microbiota composition was determined by analyzing DNA extracted from stool samples using a quantitative polymerase chain reaction that specifically measured the quantity of a target gene (16S rRNA) found in Firmicutes and Bacteroidetes. Relationships between F/B and potentially related dietary, anthropometric, and fitness variables were assessed using correlation analyses with an appropriate Bonferroni adjustment (<i>p</i> < .004). The average F/B ratio in all participants was 0.94 ± 0.03. The F/B ratio was significantly correlated to VO<sub>2</sub>max (<i>r</i> = .48, <i>p</i> < .003), but no other fitness, nutritional intake, or anthropometric variables (<i>p</i> > .004). VO<sub>2</sub>max explained ∼22% of the variance of an individual's relative gut bacteria as determined by the F/B ratio. These data support animal findings, demonstrating a relationship between relative human gut microbiota composition and cardiorespiratory fitness in healthy young adults. Gastrointestinal bacteria is integral in regulating a myriad of physiological processes, and greater insight regarding ramifications of exercise and nutrition on gut microbial composition may help guide therapies to promote human health.
DNA melting in the presence of fluorescent intercalating oxazole yellow dyes measured with a gel‐based assay (2002)

We measured the effect of the intercalating oxazole yellow DNA dye quinolinium,4-[(3-methyl-2(3H)-benzoxazolylidene)methyl]-1-[3-(trimethylammonio)propyl]-,diiodide (YO-PRO) and its homodimer (YOYO) on the melting of self-complementary DNA duplexes using a gel-based assay. The assay, which requires a self-complementary DNA sequence, is independent of the optical properties of the molecules in solution. The melting temperature of the DNA is observed to increase in direct proportion to the number of occupied intercalation sites on the DNA, irrespective of whether the dye molecules are in monomer or dimer form. The increase is approximately 2.5 degrees C for each intercalation site occupied in the presence of 38 mM [Na(+)], for dye/duplex ratios in which less than 1/5 of the available intercalation sites are occupied.
Overexpression of p27Kip1 inhibits the growth of both normal and transformed human mammary epithelial cells. (1998)

We previously reported increased expression of p27Kip1 in a series of human breast cancer cell lines, as compared to cell lines established from normal mammary epithelial cells. These data were surprising because this protein exerts a growth-inhibitory function in normal cells, and p27Kip1 has been proposed as a candidate tumor suppressor gene. A possible explanation for the paradoxical increase in p27Kip1 in the breast cancer cell lines is that they had become refractory to the inhibitory effects of this protein. To address this question, here, we transfected the MCF7 breast cancer cell line and the MCF10F nontumorigenic mammary epithelial cell line with a vector containing the p27Kip1 cDNA to obtain derivatives that express increased levels of p27Kip1. The increased expression of p27Kip1 in both of these cell lines was associated with lengthening of the G1 phase, an increase in the doubling time, a decreased saturation density, and a decreased plating efficiency. In the MCF7 cells, anchorage-independent growth and in vivo tumorigenicity were also suppressed. These effects were associated with decreased cyclin E-associated in vitro kinase activity in both cell lines. The increased expression of p27Kip1 was associated with a decreased level of expression of cyclin D1 in the MCF10F cells but an increased level of the cyclin D1 protein in the MCF7 cell line. Both derivatives expressed slightly increased levels of the cyclin E protein. Thus, breast cancer cells are still responsive to p27Kip1-mediated inhibition of cell growth despite the high basal level of this protein. These results suggest that therapeutic strategies that further increase the level of expression of p27Kip1 or mimic its activity might be useful in cancer therapy.
AUTOMATED IMPROVING AND FORMING WORDNET SYNSETS ON CONVENTIONAL (NON COMPUTER BASED) SYNONYM AND BILINGUAL DICTIONARIES (2009)

WordNet is an on-line lexical database of English language. Word meanings are represented by synonym sets (synsets). Each synset corresponds to one lexical concept. Different lexical and semantic relations link the synsets. An algorithm for automated forming Bulgarian synsets, corresponding to WordNet synsets, is presented. The three main steps of the algorithm are: I Automated improving of synsets on synonym dictionary that includes discovering synsets representing one concept; synsets which contain words for two or more different concepts; synsets with missed or incorrect synonyms placed in them, etc.; II. Finding a correspondence between lines of Englilish-Bulgarian Dictionary and WordNet synsets; III. Forming Bulgarian synsets coresponding to 55,000 WordNet concepts, using results from steps I. and II.
A programmable, multi-format photonic transceiver platform enabling flexible optical networks (2015)

Development of programmable photonic devices for future flexible optical networks is ongoing. To this end, an innovative, multi-format QAM transmitter design is presented. It comprises a segmented-electrode InP IQ-MZM to be fabricated in InP, which can be directly driven by low-power CMOS logic. Arbitrary optical QAM format generation is made possible using only binary electrical signals, without the need for high-performance DACs and high-swing linear drivers. The concept enables a host of Tx-side DSP functionality, including the spectral shaping needed for Nyquist-WDM system concepts. In addition, we report on the development of an optical channel MUX/DEMUX, based on arrays of microresonator filters with reconfigurable bandwidths and center wavelengths. The device is intended for operation with multi-format flexible transceivers, enabling Dense (D)WDM superchannel aggregation and arbitrary spectral slicing in the context of a flexible grid environment.
Zona‐induced acrosome reaction of hamster spermatozoa (1988)

It is well established that the zonae pellucidae of mature unfertilized eggs have the ability to induce the acrosome reaction of capacitated spermatozoa. To determine if this capacity of the zona is species-specific, hamster spermatozoa were allowed to attach to the zonae of homologous and heterologous eggs and examined for the acrosome reaction. The zonae of eggs from six different species were tested and the zona of hamster egg was found to have the strongest capacity to induce the acrosome reaction of hamster spermatozoa, followed by human and rat zonae. The zonae and mouse, guinea pig, and domestic fowl eggs were incapable of inducing the acrosome reaction of hamster spermatozoa. The acrosome reaction-inducing ability of the hamster zona was found to increase during maturation in the ovary. The zona of mature unfertilized hamster eggs maintained their acrosome reaction-inducing ability even after aldehyde fixation or storage in a highly concentrated solution of ammonium sulfate.
Human Action Recognition Via Fused Kinematic Structure and Surface Representation (2013)

Human action recognition from visual data has remained a challenging problem in the field of computer vision and pattern recognition. This dissertation introduces a new methodology for human action recognition using motion features extracted from kinematic structure, and shape features extracted from surface representation of human body. Motion features are used to provide sufficient information about human movement, whereas shape features are used to describe the structure of silhouette. These features are fused at the kernel level using Multikernel Learning (MKL) technique to enhance the overall performance of human action recognition. In fact, there are advantages in using multiple types of features for human action recognition, especially, if the features are complementary to each other (e.g. kinematic/motion features and shape features). For instance, challenging problems such as inter-class similarity among actions and performance variation, which cannot be resolved easily by using a single type of feature, can be handled by fusing multiple types of features. This dissertation presents a new method for representing the human body surface provided by depth map (3-D) using spherical harmonics representation. The advantage of using the spherical harmonics representation is to represent the whole body surface into a nite series of spherical harmonics coefficients. Furthermore, these series can be used to describe the pose of the body using the phase information encoded inside the coefficients. Another method for detecting/tracking distal limb segments using the kinematic structure is developed. The advantage of using the distal limb segments is to extract discriminative features that can provide sufficient and compact information to recognize human actions. Our experimental results show that the aforementioned methods for human action description are complementary to each other. Hence, combining both features can enhance the robustness of action recognition. In this context, a framework to fuse multiple features using MKL technique is developed. The experimental results show that this framework is promising in incorporating multiple features in different domain for automated recognition of human actions
Short-range order and strain in SiGeC alloys probed by phonons (2001)

We report a detailed study of the dependence of the vibrational modes in rapid thermal chemical vapor deposition grown Si1−x−yGexCy samples on substitutional carbon concentration. The difficulty in incorporating substitutional carbon in these alloys with concentrations higher than a few tenths of an atomic percent is well known. We show that simultaneous analysis of x-ray diffraction, infrared absorption, and Raman scattering measurements can be used to determine the fraction of substitutional carbon from the total carbon content. We claim that the uncertainty in defining this fraction led to the discrepancies between the interpretations of previous studies. The frequency shifts of the C local modes and the Si–Si mode are studied, in addition to the intensity dependence of the former. The evolution of C satellite peaks and their dependence on total C concentration are presented. There is a large frequency change of these modes, indicating a very large local bond distortion induced by the presence of carbon in the lattice. We show that the shifts of the Si–Si mode frequencies due to the Ge and C content are not simply the addition of each contribution separately. The rate at which they shift with changing C concentration depends on the Ge content in the alloy. The probability of creating ordered substitutional C–C pairs, rather than randomly distributed C atoms in the crystal lattice, increases nonlinearly as a function of the carbon content.
