Time of Arrival Based Localization in Wireless Sensor Networks : A Non-Linear Approach (2015)

In this paper, we aim to obtain the location information of a sensor node deployed in a Wireless Sensor Network (WSN). Here, Time of Arrival based localization technique is considered. We calculate the position information of an unknown sensor node using the non-linear techniques. The performances of the techniques are compared with the Cramer Rao Lower bound (CRLB). Non-linear Least Squares and the Maximum Likelihood are the non-linear techniques that have been used to estimate the position of the unknown sensor node. Each of these non-linear techniques are iterative approaches, namely, Newton Raphson estimate, Gauss Newton Estimate and the Steepest Descent estimate for comparison. Based on the results of the simulation, the approaches have been compared. From the simulation study, Localization based on Maximum Likelihood approach is having higher localization accuracy.
Synthesis and Physiological Activity of Thiophenes and Furans with 3- and 4-Methoxyacetophenone Derivatives (2008)

The synthesis and physiological activity of thiophenes and furans with methoxyacetophenone derivatives were examined. 3-Methoxyacetophenone (1) and 4-methoxyacetophenone (2) were converted, respectively, to the oximes (3) and (4) by oximation with hydroxylamine hydrochloride, and to the primary amines (5) and (6) by reduction with LiAlH(4). The primary amine derivatives were further converted into the thiophene and furan compounds (5a) approximately (5h) and (6a) approximately (6h), respectively. Bioassay of these compounds (5a) approximately (5h) and (6a) approximately (6h) on the germination of lettuce(Lactuca satiba) seeds showed that compound (5b) exhibits growthpromoting activity.
Northern California Oncology Group protocol 6G91: response to treatment with radiation therapy and seven-drug chemotherapy in patients with glioblastoma multiforme. (1986)

The Northern California Oncology Group (NCOG) conducted a nonrandomized phase II study to evaluate the benefit of a seven-drug chemotherapy protocol (NCOG 6G91) in patients with glioblastoma multiforme (GM). Time to tumor progression was the primary end point of the study. The treatment consisted of 5-FU and lomustine administered after surgery and before radiation therapy, hydroxyurea and misonidazole during radiation therapy, and procarbazine and vincristine alternated with carmustine and 5-FU after radiation therapy. Ninety patients entered the study; data from the 64 patients with GM who completed radiation therapy and at least started the postradiation chemotherapy regimen and returned for follow-up examination are analyzed in this report. The median time to tumor progression in the 64 adequately treated patients was 42 weeks; the 25th percentile value was 60 weeks. A Cox multivariate analysis showed that age and extent of surgical resection were important prognostic variables in patients with GM. The results of this treatment regimen were similar to those of a previous NCOG protocol (6G61), which consisted of hydroxyurea during radiation therapy followed by chemotherapy with carmustine or a combination of lomustine, procarbazine, and vincristine.

Corneal endothelial cytotoxicity of diluted povidone–iodine (2001)

The concentrations of PI tolerated by animal endothelium in vitro and in vivo were higher than the reported bactericidal levels. These findings justify further investigation of the safety and efficacy of PI for intracameral prophylaxis during surgery.
Molecular Pathology and Personalized Medicine: The Dawn of a New Era in Companion Diagnostics—Practical Considerations about Companion Diagnostics for Non-Small-Cell-Lung-Cancer (2016)

Companion diagnostics (CDx) have become a major tool in molecular pathology and assist in therapy decisions in an increasing number of various cancers. Particularly, the developments in lung cancer have been most impressing in the last decade and consequently lung cancer mutation testing and molecular profiling has become a major business of diagnostic laboratories. However, it has become difficult to decide which biomarkers are currently relevant for therapy decisions, as many of the new biomarkers are not yet approved as therapy targets, remain in the status of clinical studies, or still have not left the experimental phase. The current review is focussed on those markers that do have current therapy implications, practical implications arising from the respective companion diagnostics, and thus is focused on daily practice.
SORPTION BEHAVIOUR OF MOLYBDENUM ON DIFFERENT METAL OXIDE ION EXCHANGERS (1988)

ABSTRACT The thermal desorption of molybdenum(VI)-oxide from an inorganic adsorber matrix is an efficient new procedure for the final purification of fission molybdenum from inorganic and organic impurities. The investigations presented in this paper served to find out suitable thermally resistant inorganic ion exchangers and practical loading conditions for the preceding chromatographic sorption of molybdate anions from the process solution, in batch distribution experiments the influence of HN03-molarity, Mo-concentration and molybdenum loading on the Mo-sorption of AI2O3, Sn02, Mn02 and Sb2O5 is described in terms of their retention capacities and distribution coefficients. It could be confirmed that the retention capacity - as expected -depends strongly on the specific surface area, crystallinity and acidity of the oxide. AI203 and Sn02 with capacities of 30 and 4.7 mg Mo/g ion exchanger, respectively, proved to be superior to Mn02 and Sb205 owing to their faster Mo-sorption and better stability against abrasion.
Reactive power control of a wind farm made up with doubly fed induction generators. II (2002)

Electrical systems endowed with variable generating units are called to dominate the electrical landscape in the near future and new tools are necessary to develop in order to work in this new environment. Wind power generation is becoming one of the most important renewable energy sources in Spain and consequently, the simulation of a wind farm power performance will be an essential tool for the location of new farms. Additionally, their active/reactive power regulation possibility can become very important in the decision making process for the generator-type that has to be implemented in each wind farm. The present paper presents two different algorithms for the regulation of wind farms made up with doubly fed induction machines (DFIM), simulation results of the developed algorithms and real results of the implementation in a farm located in the North of Spain. Part II presents the developed reactive power control algorithms.
Raman microscopy for dynamic molecular imaging of living cells (2008)

We demonstrate dynamic imaging of molecular distribution in unstained living cells using Raman scattering. By combining slit-scanning detection and optimizing the excitation wavelength, we imaged the dynamic molecular distributions of cytochrome c, protein beta sheets, and lipids in unstained HeLa cells with a temporal resolution of 3 minutes. We found that 532-nm excitation can be used to generate strong Raman scattering signals and to suppress autofluorescence that typically obscures Raman signals. With this technique, we reveal time-resolved distributions of cytochrome c and other biomolecules in living cells in the process of cytokinesis without the need for fluorescent labels or markers.
Analysis of choline and atropine in hairy root cultures of <b><i>Cannabis sativa</i></b> L. by capillary electrophoresis‐electrospray mass spectrometry (2006)

We describe a capillary zone electrophoresis method coupled to electrospray ionization (ion trap) mass spectrometry (CZE-ESI-MS) for the identification and determination of choline and atropine compounds in hairy root extracts from Cannabis sativa L. Fused-silica capillary and an alkaline solution of 20 mM ammonium acetate at pH 8.5 are used being the most suitable for the analysis of choline and atropine in less than 10 min. Under the optimized conditions, including CE and ESI-MS parameters, the method resolved both compounds with very high sensitivity. The system exhibited good linear response in the range of 25-500 mg/L and 500-1000 microg/L for choline and atropine, respectively. The detection limit of choline was 18 mg/L and 320 microg/L for atropine. Finally, the developed method was applied to the analysis of these compounds in transgenic root cultures of Cannabis sativa L.
<title>CBR channels on a DQRAP-based HFC network</title> (1995)

DQRAP (distributed queuing random access protocol), is a multiple access protocol that offers a throughput equal to the offered traffic up to a load of one with a lesser delay than any other multiple access protocol. DQRAP utilizes three control minislots and two distributed queues: transmission and collision resolution, to provide this performance for all values of 'a', i.e., the size of the network is immaterial. This paper describes: (a) how DQRAP can act as the switching fabric for a distributed ATM switch serving an HFC (hybrid fiber-coax) network; and (b) how CBR (constant bit rate) traffic is supported on our distributed ATM switch, i.e., a DQRAP/ATM switch. Simulation results representing the operation of a DQRAP/ATM switch operating in two modes: (a) the control minislots in dataslots allocated to CBR traffic are utilized in the reservation process; and (b) the control minislot capacity in those slots is allocated to CBR data.
SoMeta: Scalable Object-Centric Metadata Management for High Performance Computing (2017)

Scientific data sets, which grow rapidly in volume, are often attached with plentiful metadata, such as their associated experiment or simulation information. Thus, it becomes difficult for them to be utilized and their value is lost over time. Ideally, metadata should be managed along with its corresponding data by a single storage system, and can be accessed and updated directly. However, existing storage systems in high-performance computing (HPC) environments, such as Lustre parallel file system, still use a static metadata structure composed of non-extensible and fixed amount of information. The burden of metadata management falls upon the end-users and require ad-hoc metadata management software to be developed.With the advent of "object-centric" storage systems, there is an opportunity to solve this issue. In this paper, we present SoMeta, a scalable and decentralized metadata management approach for object-centric storage in HPC systems. It provides a flat namespace that is dynamically partitioned, a tagging approach to manage metadata that can be efficiently searched and updated, and a light-weight and fault tolerant management strategy. In our experiments, SoMeta achieves up to 3.7X speedup over Lustre in performing common metadata operations, and up to 16X faster than SciDB and MongoDB for advanced metadata operations, such as adding and searching tags. Additionally, in contrast to existing storage systems, SoMeta offers scalable user-space metadata management by allowing users with the capability to specify the number of metadata servers depending on their workload.
Metabolic programming and PDHK1 control CD4+ T cell subsets and inflammation (2014)

Activation of CD4+ T cells results in rapid proliferation and differentiation into effector and regulatory subsets. CD4+ effector T cell (Teff) (Th1 and Th17) and Treg subsets are metabolically distinct, yet the specific metabolic differences that modify T cell populations are uncertain. Here, we evaluated CD4+ T cell populations in murine models and determined that inflammatory Teffs maintain high expression of glycolytic genes and rely on high glycolytic rates, while Tregs are oxidative and require mitochondrial electron transport to proliferate, differentiate, and survive. Metabolic profiling revealed that pyruvate dehydrogenase (PDH) is a key bifurcation point between T cell glycolytic and oxidative metabolism. PDH function is inhibited by PDH kinases (PDHKs). PDHK1 was expressed in Th17 cells, but not Th1 cells, and at low levels in Tregs, and inhibition or knockdown of PDHK1 selectively suppressed Th17 cells and increased Tregs. This alteration in the CD4+ T cell populations was mediated in part through ROS, as N-acetyl cysteine (NAC) treatment restored Th17 cell generation. Moreover, inhibition of PDHK1 modulated immunity and protected animals against experimental autoimmune encephalomyelitis, decreasing Th17 cells and increasing Tregs. Together, these data show that CD4+ subsets utilize and require distinct metabolic programs that can be targeted to control specific T cell populations in autoimmune and inflammatory diseases.
Perovskite Tandem Solar Cells (2017)

The meteoric rise of perovskite single‐junction solar cells has been accompanied by similar stunning developments in perovskite tandem solar cells. Debuting with efficiencies less than 14% in 2014, silicon–perovskite solar cells are now above 25% and will soon surpass record silicon single‐junction efficiencies. Unconstrained by the Shockley–Quiesser single‐junction limit, perovskite tandems suggest a real possibility of true third‐generation thin‐film photovoltaics; monolithic all‐perovskite tandems have reached 18% efficiency and will likely pass perovskite single‐junction efficiencies within the next 5 years. Inorganic–organic metal–halide perovskites are ideal candidates for inclusion in tandem solar cells due to their high radiative recombination efficiencies, excellent absorption, long‐range charge‐transport, and broad ability to tune the bandgap. In this progress report, the development of perovskite tandem cells is reviewed, with presentation of their key motivations and challenges. In detail, it presents an overview of recombination layer materials, bandgap‐tuneability, transparent contact architectures, and perovskite compounds for use in tandems. Theoretical estimates of efficiency for future tandem and triple‐junction perovskite cells are presented, outlining roadmaps for future focused research.
Using mutual information to resolve query translation ambiguities and query term weighting (1999)

An easy way of translating queries in one language to the other for cross-language information retrieval (IR) is to use a simple bilingual dictionary. Because of the general-purpose nature of such dictionaries, however, this simple method yields a severe translation ambiguity problem. This paper describes the degree to which this problem arises in Korean-English cross-language IR and suggests a relatively simple yet effective method for disambiguation using mutual information statistics obtained only from the target document collection. In this method, mutual information is used not only to select the best candidate but also to assign a weight to query terms in the target language. Our experimental results based on the TREC-6 collection shows that this method can achieve up to 85% of the monolingual retrieval case and 96% of the manual disambiguation case.
Gadolinium complexes of [(myristoyloxy)propyl]diethylenetriaminetetraacetate: new lipophilic, fatty acyl conjugated NMR contrast agents (1992)

New lipophilic contrast agents, 1-[3'-(myristoyloxy)propyl]diethylenetriamine-1,4,7,7-tetraacetic acid (1MP-DTTA), 4-[3'-(myristoyloxy)propyl]diethylenetriamine-1,1,7,7-tetraacetic acid (4MP-DTTA), and 4-[3'-(myristoyloxy)propyl]-2,6-dioxodiethylenetriamine-1,1, 7, 7-tetraacetic acid (4MPD-DTTA), were prepared from either diethylenetriamine or 3-amino-1-propanol (overall yield 16-23%). Liposome-incorporated Gd complexes of ligands 1MP-DTTA, 4MP-DTTA, and 4MPD-DTTA were prepared by mixing GdCl3 and the prepared vesicles consisting of ligand, egg lecithin, and cholesterol (molar ratio 1.1:5.1) followed by further sonication, and their in vitro relaxivities were determined. The relaxivities of these agents were higher than those of the Gd3+ aquoion, Gd(EDTA), or Gd(DTPA) at both 0.23 and 0.47 T. Gd(4MPD-DTTA) displayed the highest relaxivities (24.0 +/- 0.4 and 34.7 +/- 0.4, at 0.23 and 0.47 T, respectively) among these new Gd complexes. The relaxivities of these three agents increased from the lower to the higher magnetic field, indicating a positive field dependence. Stability constants (log K) of Gd(1MP-DTTA), Gd(4MP-DTTA), and Gd(4MPD-DTTA) were found to be 18.2 +/- 0.2, 18.4 +/- 0.2, and 15.7 +/- 0.8, respectively. A lower limit of 0.3 mmol/kg was found for LD50 for these three agents.
[Effect of glutamate and combined with inosine monophosphate on gastric secretion]. (1994)

Experiments on dogs with Pavlov pouch and gastric fistula demonstrate that monosodium glutamate (MSG) enriched with inosine monophosphate (IMP) potentiate pentagastrin-induced gastric secretion. The preparation (Chi-Mi) was introduced directly into the intestine through a fistula. When given alone in an equal quantity MSG produced the same effect. In per os administration Chi-Mi was more effective, probably due to a different response of the gustatory receptors to MSG and Chi-Mi. When the latter two were added to meat used as a food stimulus, Chi-Mi brought about more intensive gastric secretion in all its phases. In sham feeding Chi-Mi also intensified the secretion augmenting the reflex phase of gastric secretion when added to food substances. The findings may appear helpful in further search for medical application of glutamate and allied substances.
The Warrigal Dataset: Multi-Vehicle Trajectories and V2V Communications (2014)

Intelligent Transportation Systems rely on understanding, predicting and affecting the interactions between vehicles. Development of such systems must be based upon data derived from actual interactions if they are to be effective when used in real world applications. Increasingly, systems are being developed that are based on radio communication of state and intent between vehicles. Understanding of how these interactions occur is also necessary to creating robust systems. In order to test and compare new techniques, approaches and algorithms it is necessary to have a rich dataset to experiment with. This paper presents a detailed dataset useful for members of the Intelligent Transportation Systems community. It contains vehicle state information, vehicle-to-vehicle communications and road maps at high temporal resolution for large numbers of interacting vehicles over a long time period. This data set has already been used for a number of Intelligent Transportation Systems projects such as road mapping, driver intent prediction and collision avoidance among others.
The line drawing editor, an experiment in computer vision (1976)

A computer program, the Line Drawing Editor (LDE), that allows convenient modification of computer representations of simple line drawings has been designed and implemented. The distinguishing feature of the LDE from the multitude of interactive graphics programs that accomplish the same function is the use of a computer controlled TV camera for input and program control rather than conventional interactive input devices such as light pens or data tablets. A graphical editing language allows the LDE user to indicate, by marking the drawing in appropriate fashion, the changes that are to be made. The drawing, which was generated on a hardcopy output device, with the added edit information is placed in front of the camera. In successive phases the LDE computes a two dimensional homogeneous transformation relating the viewed drawing and its computer description, locates the lines added to the drawing, parses the added lines according to the edit language and finally uses this information to update the drawing description.
Recent Epidemiological Status of Canine Viral Enteric Infections and Giardia Infection in Japan. (2001)

Epidemiology of canine enteric infections was studied. Rectal swabs collected from 95 dogs presented at animal hospitals during a period from January to June of 2000 were examined for enteric pathogens, including viruses and Giardia lamblia (G. lamblia). Most frequently detected in both diarrheal and normal feces were canine coronavirus (55.4%) and G. lamblia (48.2%). Canine parvovirus type 2 (CPV-2) was specifically associated with diarrheal cases and CPV-2b was the predominant antigenic type. Although canine rotavirus, canine adenovirus, and canine distemper virus were also detected in a small number of diarrheal cases, no evidence for calicivirus infection was obtained.
Revised Constitution of Sclerophytins A and B (2000)

Facilitated transport of oxygen in ethyl cellulose membranes containing cobalt porphyrins as oxygen carriers (2000)

Facilitated transport of oxygen was investigated in ethyl cellulose membranes containing cobalt(II) meso-tetrakis (substituted phenyl) porphyrins [CoTPP, CoT(2-Cl)PP, CoT(4-Cl)PP, CoT(4-MeO)PP, and CoT(2,4-2MeO)PP] as fixed oxygen carriers. The oxygen permeability (P) and oxygen/nitrogen selectivity (P/P) of the membranes containing oxygen carriers increase with a decrease in the upstream gas pressure, but the nitrogen permeability (P) is almost independent of the upstream nitrogen pressure. This indicates that the fixed oxygen carriers in the polymer membranes can reversibly interact with oxygen and facilitate oxygen transport in the membranes. The study on the influences of the substituents in the cobalt(II) porphyrins and the fifth ligand (imidazole or pyridine) on the membrane permeation behaviors shows that the porphyrin complex with an electron-accepting substituent in the meso-phenyl ring or with imidazole as the fifth ligand could increase the permeability and oxygen/nitrogen selectivity of the membranes much more than that with an electron-donating substituent or with pyridine as the fifth ligand. © 2000 John Wiley & Sons, Inc.

Quantitative Description of Glycan-Receptor Binding of Influenza A Virus H7 Hemagglutinin (2013)

In the context of recently emerged novel influenza strains through reassortment, avian influenza subtypes such as H5N1, H7N7, H7N2, H7N3 and H9N2 pose a constant threat in terms of their adaptation to the human host. Among these subtypes, it was recently demonstrated that mutations in H5 and H9 hemagglutinin (HA) in the context of lab-generated reassorted viruses conferred aerosol transmissibility in ferrets (a property shared by human adapted viruses). We previously demonstrated that the quantitative binding affinity of HA to α2→6 sialylated glycans (human receptors) is one of the important factors governing human adaptation of HA. Although the H7 subtype has infected humans causing varied clinical outcomes from mild conjunctivitis to severe respiratory illnesses, it is not clear where the HA of these subtypes stand in regard to human adaptation since its binding affinity to glycan receptors has not yet been quantified. In this study, we have quantitatively characterized the glycan receptor-binding specificity of HAs from representative strains of Eurasian (H7N7) and North American (H7N2) lineages that have caused human infection. Furthermore, we have demonstrated for the first time that two specific mutations; Gln226→Leu and Gly228→Ser in glycan receptor-binding site of H7 HA substantially increase its binding affinity to human receptor. Our findings contribute to a framework for monitoring the evolution of H7 HA to be able to adapt to human host.
