A 400μW-RX, 1.6mW-TX superregenerative transceiver for wireless sensor networks (2005)

A fully integrated 2GHz super-regenerative transceiver is implemented in a 0.13 /spl mu/m CMOS process. The transmit and receive paths utilize BAW resonators, yielding a 450 /spl mu/W 1V RF front-end and a transmitter delivering 380 /spl mu/W with 23% efficiency. At 5kb/s, the receiver achieves a sensitivity of -100.5dBm for 10/sup -3/ BER.
Feature-aided localization of ground vehicles using passive acoustic sensor arrays (2009)

Localization of moving ground targets using acoustic signals obtained by a passive sensor network, made up of acoustic sensor arrays on the ground, is a difficult problem as the signals are contaminated by wind noise and hampered by road conditions and multipath, etc., and are generally not deterministic. It becomes even more challenging when some of the vehicles are wheeled (e.g., cars) and some are tracked (e.g., tanks), and are closely spaced. In such cases the stronger acoustic signals from the tracked vehicles can mask those from the wheeled vehicles, leading to poor detection of such targets. A novel detection scheme is presented, according to which the direction of arrival (DoA) angle estimates of emitters are obtained by each sensor array using real data. The full position estimates of targets, obtained following the association of the DoA angle estimates of the same target from at least three sensor arrays, are used for target tracking. However, because of the particular challenges encountered in multiple ground vehicle scenarios, this association is not always reliable and thus, target tracking using kinematic (DoA angle) measurements only is difficult and it can lead to lost tracks. In this paper we propose a new feature-aided multidimensional assignment algorithm, to augment the existing assignment algorithms which use only kinematic measurements, to improve the association performance, especially in the case of wheeled vehicles. We present a novel frequency domain feature extraction technique by implementing a statistical characterization of the features, in order to enhance the accuracy of data association. The feature and DoA angle measurements are used simultaneously, via a joint likelihood function, in a multidimensional assignment (MDA) to localize targets.
Chiral Seleno-Amines from Indium Selenolates. A Straightforward Synthesis of Selenocysteine Derivatives (2006)

A simple and efficient procedure for the synthesis of chiral beta-seleno-amines derivatives from a one-pot indium(I) iodide-mediated aziridine ring opening with diorganoyl diselenides has been developed. As an application, the synthesis of selenocysteine and selenotreonine derivatives has been accomplished.
STAT3 Is Required for Proliferation and Maintenance of Multipotency in Glioblastoma Stem Cells (2009)

Signal transducer and activator of transcription 3 (STAT3) regulates diverse cellular processes, including cell growth, differentiation, and apoptosis, and is frequently activated during tumorigenesis. Recently, putative glioblastoma stem cells (GBM-SCs) were isolated and characterized. These cells can self-renew indefinitely in culture, are highly tumorigenic, and retain the ability to differentiate in culture. We have found that treatment of GBM-SCs with two chemically distinct small molecule inhibitors of STAT3 DNA-binding inhibits cell proliferation and the formation of new neurospheres from single cells. Genetic knockdown of STAT3 using a short hairpin RNA also inhibits GBM-SC proliferation and neurosphere formation, confirming that these effects are specific to STAT3. Although STAT3 inhibition can induce apoptosis in serum-derived GBM cell lines, this effect was not observed in GBM-SCs grown in stem cell medium. Markers of neural stem cell multipotency also decrease upon STAT3 inhibition, suggesting that STAT3 is required for maintenance of the stem-like characteristics of these cells. Strikingly, even a transient inhibition of STAT3 leads to irreversible growth arrest and inhibition of neurosphere formation. These data suggest that STAT3 regulates the growth and self-renewal of GBM-SCs and is thus a potential target for cancer stem cell-directed therapy of glioblastoma multiforme.
Importance of disrupted intestinal barrier in inflammatory bowel diseases (2010)

The current paradigm of inflammatory bowel diseases (IBD), both Crohn's disease (CD) and ulcerative colitis (UC), involves the interaction between environmental factors in the intestinal lumen and inappropriate host immune responses in genetically predisposed individuals. The intestinal mucosal barrier has evolved to maintain a delicate balance between absorbing essential nutrients while preventing the entry and responding to harmful contents. In IBD, disruptions of essential elements of the intestinal barrier lead to permeability defects. These barrier defects exacerbate the underlying immune system, subsequently resulting in tissue damage. The epithelial phenotype in active IBD is very similar in CD and UC. It is characterized by increased secretion of chloride and water, leading to diarrhea, increased permeability via both the transcellular and paracellular routes, and increased apoptosis of epithelial cells. The main cytokine that seems to drive these changes is tumor necrosis factor alpha in CD, whereas interleukin (IL)-13 may be more important in UC. Therapeutic restoration of the mucosal barrier would provide protection and prevent antigenic overload due to intestinal "leakiness." Here we give an overview of the key players of the intestinal mucosal barrier and review the current literature from studies in humans and human systems on mechanisms underlying mucosal barrier dysfunction in IBD.
Effects of brefeldin A and accessory proteins on association of ADP-ribosylation factors 1, 3, and 5 with Golgi (1993)

ADP-ribosylation factors (ARFs) are approximately 20-kDa guanine nucleotide-binding proteins initially identified by their ability to enhance in vitro cholera toxin-catalyzed ADP-ribosylation and subsequently shown to participate in vesicular transport in the Golgi and other cellular compartments. By cDNA and genomic cloning, at least six mammalian ARFs were identified. Brefeldin A (BFA) disrupts Golgi membranes and inhibits binding of soluble high molecular weight proteins to Golgi fractions. We examined the effects of BFA on binding of ARF1, -3, and -5 to a Golgi fraction in the presence of an ATP-regenerating system and a fraction of soluble, high molecular weight, accessory proteins (SAP), presumably containing complexes identified by others as coatomers that are involved in vesicular transport. ARF binding in all instances was dependent on guanosine 5'-O-(3-thiotriphosphate) and increased by the ATP-regenerating system. Binding of ARF1 and -3, but not ARF5, was enhanced by SAP. BFA inhibited the SAP-dependent, but not the SAP-independent, binding of ARF1 and -3. It had no effect on the increment in binding produced by an ATP-regenerating system. B36, an inactive derivative of BFA, did not inhibit SAP-dependent binding of ARF1 and -3. Binding of ARF5, which was SAP-independent, was not affected by BFA. These observations are consistent with the conclusion that mammalian ARFs differ in their dependence on accessory proteins for interaction with Golgi and, perhaps, other cellular membranes and that BFA specifically inhibits SAP-dependent ARF binding.
Reduction of Metal Oxides by Electron Cyclotron Resonance (ECR) Plasma of Hydrogen–A Model Study on Discharge Cleaning (1980)

A reduction experiment on oxides of Cu, Ni, Fe, Mo and Ti was carried out, using a low electron temperature ECR plasma of hydrogen. Reduction rates of these oxides were estimated by observing the disappearance of interference rings of oxide layers. The reduction efficiency η of H + flux was evaluated; η=0.4 for copper oxide and 10 -3 <η<10 -2 for other oxides. Roughly, the reduction rate decreased with an increase in the metal-oxygen binding energy. It was shown that oxide layers with a thickness in the order of magnitude 10 -1 µm were reduced without difficulty. It is of interest from the viewpoint of discharge cleaning of fusion-oriented machines.
<i>Mycobacterium avium</i>Genes Associated with the Ability To Form a Biofilm (2006)

Mycobacterium avium is widely distributed in the environment, and it is chiefly found in water and soil. M. avium, as well as Mycobacterium smegmatis, has been recognized to produce a biofilm or biofilm-like structure. We screened an M. avium green fluorescent protein (GFP) promoter library in M. smegmatis for genes involved in biofilm formation on polyvinyl chloride (PVC) plates. Clones associated with increased GFP expression > or =2.0-fold over the baseline were sequenced. Seventeen genes, most encoding proteins of the tricarboxylic acid (TCA) cycle and GDP-mannose and fatty acid biosynthesis, were identified. Their regulation in M. avium was confirmed by examining the expression of a set of genes by real-time PCR after incubation on PVC plates. In addition, screening of 2,000 clones of a transposon mutant bank constructed using M. avium strain A5, a mycobacterial strain with the ability to produce large amounts of biofilm, revealed four mutants with an impaired ability to form biofilm. Genes interrupted by transposons were homologues of M. tuberculosis 6-oxodehydrogenase (sucA), enzymes of the TCA cycle, protein synthetase (pstB), enzymes of glycopeptidolipid (GPL) synthesis, and Rv1565c (a hypothetical membrane protein). In conclusion, it appears that GPL biosynthesis, including the GDP-mannose biosynthesis pathway, is the most important pathway involved in the production of M. avium biofilm.

Tire Cord (2000)

Abstract The development of various tire cord materials such as cotton, rayon, nylon, steel, polyester, fiber glass, and aramid used for the reinforcement of pneumatic tire is reviewed. Balanced properties developed through tailored cord–rubber composite laminates required for optimum tire performance are described. A general overview of tire cord materials and subsequent processing steps necessary for the laminate structure integrity during varying tire service conditions are presented. Typical chemical and physical properties pertinent to anisotropic cord–rubber composites are also described. Attempts to correlate cord mechanics and nonlinear viscoelastic responses of cord–rubber laminates with tire performance are reviewed. Tire cord laboratory test methods used for chemical and physical characterization are described. The importance of tire cord cost structure and its value governed by tire performance is depicted. In addition, environmental factors affecting vehicle design leading to research efforts for future tire cord materials with high strength‐to‐weight ratio is postulated.

A 1.25MS/S Two-Step Incremental ADC with 100DB DR and 110DB SFDR (2018)

This paper presents a two-step incremental ADC (IADC) with extended counting. The proposed IADC has only one active integrator in the two-step conversion cycle. To achieve high accuracy without trimming or calibration, a cyclic ADC with a 31-level quantizer is used in the second step. Fabricated in 0.18 μm CMOS process, the prototype ADC occupies 0.72 mm <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">2</sup> . With a 55 MHz clock, the measured dynamic range and SFDR are 100 dB and 110 dB, respectively, at a conversion rate of 1.25 MS/s. The power consumption is 27.7 mW from a 3 V power supply. This gives a Schreier FoM of 173.6 dB.
Evaluation of Soybean–Navy Bean Emulsions Using Different Processing Technologies (2017)

In this study, an innovative emulsion made from soybean and navy bean blends of different proportionalities was developed. In addition, two processing methods were used: traditional cooking and jet-cooking. The physical attributes and storage stability were measured and compared. This study found that the high content of starch and fiber in navy bean flour contributes to the increase in viscosity of the emulsions, at both room and refrigeration temperatures, as the proportion of navy bean flour in the blends increased. The steam jet-cooked emulsions with higher soybean content has better shelf life stability, smaller particle size, higher fat, lower starch, and lower viscosity, whereas the traditional kettle cooking method is better in reducing anti-nutritional components. No significant difference was found between the two cooking methods in terms of nutritional contents in the emulsions, such as protein, crude fat, and total starch. The traditional kettle cooking, with its longer cooking time, seems to reduce more trypsin inhibitor in the emulsions than those prepared with the steam jet-cooking. This exploratory study is the first to report soybean–navy bean beverage prototypes having desirable nutritional value and the potential for functional beverage market.
Introduction of Genes Encoding C4 Photosynthesis Enzymes into Rice Plants: Physiological Consequences (2007)

Transgenic rice plants expressing the maize phosphoeno/pyruvate carboxylase (PEPC) and pyruvate, orthophosphate dikinase (PPDK) exhibit a higher photosynthetic capacity (up to 35%) than untransformed plants. The increased photosynthetic capacity in these plants is mainly associated with an enhanced stomatal conductance and a higher internal CO2 concentration. Plants simultaneously expressing high levels of both enzymes also have a higher photosynthetic capacity. The results suggest that both PEPC and PPDK play a key role in organic acid metabolism in the guard cells to regulate stomatal opening. Under photoinhibitory and photooxidative conditions, PEPC transgenic rice plants are capable of maintaining a higher photosynthetic rate, a higher photosynthetic quantum yield by PSII and a higher capacity to dissipate excess energy photochemically and non-photochemically than untransformed plants. Preliminary data from field trials show that relative to untransformed plants, the grain yield is about 10-20% higher in selected PEPC and 30-35% higher in PPDK transgenic rice plants, due to increased tiller number. Taken together, these results suggest that introduction of C4 photosynthesis enzymes into rice has a good potential to enhance its tolerance to stress, photosynthetic capacity and yield.
Design of Architecture for Efficient Integration of Internet of Things and Cloud Computing (2017)

With a penchant of computing everywhere, everything is going to be connected to the Internet and its data will be used for various progressive purposes. All such required things are connected over the internet and communication is established between them. All the things which are connected may generate data, sometimes data may be used immediately and in some cases data has to be processed and stored for future use. So here comes the use of cloud, the data can be stored in cloud and can be used whenever required. The integration of cloud computing and Internet of Things (IoT) can enable the resource sharing more efficiently than before. From many surveys it is found that integration of IoT and cloud computing is in its initial phase and it has not extended to all application domains due to its inadequate security architecture. So, the paper discusses a secured architecture and the issues involved. The cloud services are integrated through a novel IP/MPLS (Internet Protocol/ Multiprotocol Label Switching) core. Elliptic Curve Cryptography (ECC) is used to ensure complete protection against the security risks. However, new challenges arise when cloud is integrated with IoT. The paper proposes an idea to integrate Internet of Things and Cloud Computing in order to increase the efficiency of computing environment and meet the challenges of speed and accuracy of the services extended by the providers. Keywords: IOT, cloud computing, Elliptic Curve Cryptography, IP/MPLS core, Architecture.

Domains and Maturation Processes That Regulate the Activity of ADAMTS-2, a Metalloproteinase Cleaving the Aminopropeptide of Fibrillar Procollagens Types I–III and V (2005)

Processing of fibrillar collagens is required to generate collagen monomers able to self-assemble into elongated and cylindrical collagen fibrils. ADAMTS-2 belongs to the "A disintegrin and metalloproteinase with thrombospondin type 1 motifs" (ADAMTS) family. It is responsible for most of the processing of the aminopropeptide of type I procollagen in the skin, and it also cleaves type II and type III procollagens. ADAMTS are complex secreted enzymes that are implicated in various physiological and pathological processes. Despite accumulating evidence indicating that their activity is regulated by ancillary domains, additional information is required for a better understanding of the specific function of each domain. We have generated 17 different recombinant forms of bovine ADAMTS-2 and characterized their processing, activity, and cleavage specificity. The results indicated the following: (i) activation of the ADAMTS-2 zymogen involves several cleavages, by proprotein convertases and C-terminal processing, and generates at least seven distinct processed forms; (ii) the C-terminal domain negatively regulates enzyme activity, whereas two thrombospondin type 1 repeats are enhancer regulators; (iii) the 104-kDa form displays the highest aminoprocollagen peptidase activity on procollagen type I; (iv) ADAMTS-2 processes the aminopropeptide of alpha1 type V procollagen homotrimer at the end of the variable domain; and (v) the cleaved sequence (PA) is different from the previously described sites ((P/A)Q) for ADAMTS-2, redefining its cleavage specificity. This finding and the existence of multiple processed forms of ADAMTS-2 strongly suggest that ADAMTS-2 may be involved in function(s) other than processing of fibrillar procollagen types I-III.

Radiation-Induced Apoptosis in Thymocytes: Inhibition by Diethyldithiocarbamate and Zinc (1996)

Apoptosis is a process of physiological cell death characterized by DNA fragmentation, chromatin condensation, loss of membrane asymmetry, mitochondrial alterations and cell lethality. In the present study, apoptosis induced in thymocytes by gamma irradiation is evaluated by flow cytometry, by a diphenylamine colorimetric method and by gel electrophoresis. Treatment of thymocytes with diethyldithiocarbamate or zinc shows that these compounds can inhibit radiation-induced apoptosis. Moreover, a synergistic effect is observed by using combinations of both compounds: ZnSO4 potentiates the effect of diethyldithiocarbamate at concentrations at which the compounds used separately show a low efficacy. A study of kinetics shows that addition of 1 microM diethyldithiocarbamate + 50 microM ZnSO4 (the most efficient combination) after irradiation can decrease DNA fragmentation even when it is added 2-3 h after irradiation. However, 1 microM diethyldithiocarbamate + 50 microM ZnSO4 cannot prevent the radiation-induced loss of membrane asymmetry and the decrease in alteration of the mitochondrial membrane as measured by binding of merocyanine 540 and uptake of rhodamine 123, respectively.

Descripción sistemática del "Pez Graso" del Lago de Tota (Boyacá) (1942)

La especie P. totae se distingue fácilmente de los demás miembros conocidos de la familia Pygidiidae por sus anillos grasos, que semejan una serie de llantas de automóvil, y especialmente por las dos ampollas occipitales de forma peculiarísima; por su apariencia repugnante; por su olor a manteca; y por la posición adelantada de la unión de las membranas branquiales.
