Compuestos antifúngicos en Prosopis ruscifolia: identificación y análisis de su utilidad en el control de especies toxigénicas de Aspergillus (2018)

Se requieren nuevos agentes antifúngicos capaces de controlar a hongos del género Aspergillus que provocan pudriciones en maíz especialmente en granos almacenados, contaminándolos con aflatoxinas. La ingestión de estas micotoxinas puede ocasionar intoxicaciones en humanos y animales. El control químico de especies de Aspergillus se restringe al uso de preservantes de grado alimenticio, los cuales son fungistáticos, pueden alterar las características organolépticas del grano y en dosis subinhibitorias del crecimiento micelial pueden estimular la producción de aflatoxinas. Plantas autóctonas del NOA conocidas popularmente por sus propiedades antisépticas podrían proveer metabolitos secundarios capaces de detener el progreso de estos hongos. El objetivo de este trabajo fue determinar la actividad antifúngica de extractos de vinal (Prosopis ruscifolia) sobre especies de Aspergillus e identificar los metabolitos responsables. Partes aéreas de P. ruscifolia se extrajeron secuencialmente con hexano, diclorometano, acetato de etilo y metanol. La actividad antifúngica de estos extractos se ensayó sobre seis cepas de Aspergillus por bioautografía de siembra puntual y por microdilución, lo que permitió determinar que solo el extracto metanólico (fMeOH) presentó actividad antifúngica sobre las especies de Aspergillus ensayadas. Las dosis mínimas inhibitorias del crecimiento fúngico (DIM) fueron de 50-200 µg/ml y las concentraciones inhibitorias del 50% y 100% del crecimiento fúngico (CI50 y CIM) fueron 60-297 µg/ml y 50-1500 µg/ml respectivamente. Los constituyentes del fMeOH se separaron mediante cromatografía en columna de sílica gel y por cromatografía preparativa en capa fina. Las moléculas antifúngicas se estudiaron mediante revelados específicos en CCF y por espectrometría de resonancia magnética nuclear (RMN), identificándose los mismos como alcaloides (Juliflorina y Juliprosineno), un ciclitol (Pinitol) y una saponina triterpénica. El fMeOH de parte aéreas de P. ruscifolia no manifestó toxicidad sobre A. salina (CL5O > 1000 ppm), lo cual indica que el mismo no presenta citotoxicidad en eucarionates.
Tool support for collaborative teaching and learning of object-oriented modeling (2002)

Modeling is central to doing and learning object-oriented development. We present a new tool, Ideogramic UML, for gesture-based collaborative modeling with the Unified Modeling Language (UML), which can be used to collaboratively teach and learn modeling. Furthermore, we discuss how we have effectively used Ideogramic UML to teach object-oriented modeling and the UML to groups of students using the UML for project assignments.
An Unconventional Human Ccr4-Caf1 Deadenylase Complex in Nuclear Cajal Bodies (2006)

mRNA deadenylation is a key process in the regulation of translation and mRNA turnover. In Saccharomyces cerevisiae, deadenylation is primarily carried out by the Ccr4p and Caf1p/Pop2p subunits of the Ccr4-Not complex, which is conserved in eukaryotes including humans. Here we have identified an unconventional human Ccr4-Caf1 complex containing hCcr4d and hCaf1z, distant human homologs of yeast Ccr4p and Caf1p/Pop2p, respectively. The hCcr4d-hCaf1z complex differs from conventional Ccr4-Not deadenylase complexes, because (i) hCaf1z and hCcr4d concentrate in nuclear Cajal bodies and shuttle between the nucleus and cytoplasm and (ii) the hCaf1z subunit, in addition to rapid deadenylation, subjects substrate RNAs to slow exonucleolytic degradation from the 3' end in vitro. Exogenously expressed hCaf1z shows both of those activities on reporter mRNAs in human HeLa cells and stimulates general mRNA decay when restricted to the cytoplasm by deletion of its nuclear localization signal. These observations suggest that the hCcr4d-hCaf1z complex may function either in the nucleus or in the cytoplasm after its nuclear export, to degrade polyadenylated RNAs, such as mRNAs, pre-mRNAs, or those RNAs that are polyadenylated prior to their degradation in the nucleus.
O-015 Contrast transit time changes on digital subtraction angiography following pipeline flow diversion (2017)

<h3>Introduction</h3> Pipeline embolization devices (PED) are used for endovascular treatment of cerebral aneurysms but can be associated with delayed ipsilateral intraparenchymal hemorrhage (DIPH). Changes in intracranial hemodynamics after PED are poorly understood. Here, we assess hemodynamic changes after PED in patients with and without DIPH. <h3>Methods</h3> Records of patients with distal internal carotid artery (ICA) aneurysms treated with PED at our institution between 2012–2017 were retrospectively reviewed. Regions of interest were selected proximally to PED over the cavernous ICA and distally over the middle cerebral artery (MCA), and then transit times were determined using syngo iFlow software (Siemens). Ratio of MCA to ICA transit time was compared before and after treatment using Wilcoxon matched-pairs signed-ranks test. Ratios were also compared between patients with and without DIPH using 2-sample Wilcoxon rank-sum test. <h3>Results</h3> 53 patients were included (mean age 56 years). Ratio of MCA to ICA transit time decreased significantly after PED deployment (1.13 vs. 1.23, p&lt;0.01, figure 1A). Ratio in DIPH + group (n=4) was significantly lower (1.00 vs. 1.13, p=0.01, Fig B) and decreased significantly more (21% vs. 4.4%, p=0.02) compared to DIPH – group (n=49). The ratio tended to be higher in larger aneurysms at baseline (p=0.07) but not after PED treatment (p=0.15). <h3>Conclusion</h3> Ratio of MCA to ICA transit time decreases more in patients with DIPH following PED treatment. These contrast transit time changes can be detected in real-time in the neuroangiography suite. <h3>Disclosures</h3> <b>D. Brunozzi:</b> None. <b>S. Shakur:</b> None. <b>F.

Engineering Evaluations of a Catalytic Membrane Reactor for the Water Gas Shift Reaction (2005)

A study of the performance of a membrane reactor (MR) for the water gas shift (WGS) reaction is presented, also pursuing the membrane engineering approach in the logic of the Process Intensification Strategy. The MR mathematical model was developed from the design equation of traditional reactors considering a H2 high-selectivity membrane, to perform a comparison between the two reactor types and experimental literature data8 and qualitatively and quantitatively estimate the convenience of MR use. The effect of the operating conditions (temperature, reaction pressure, feed flow rate, etc.) on the catalyst efficiency was also considered in addition to their influence on the reaction from kinetic and thermodynamic points of view. A catalyst effectiveness factor was calculated considering the Thiele module. It takes into account the kinetic and diffusive resistances inside the catalytic pellet, which also depend on the pellet geometric characteristics (pore diameter, pore length, tortuosity, porosity, etc.). The obtained results confirmed the advantage of the use of a MR for the WGS reaction, in terms of conversion improvement and reduction of the necessary reaction volumes and related costs.
Immobilization of Proteins in Poly-Styrene-Divinylbenzene Matrices: Functional Properties and Applications (2015)

Supports based on poly-styrene-divinylbenzene (PSD) are commercially available since a long time ago. However, they are not commonly used as enzyme immobilization matrices. The main reason for this lies in the negative effect of the very hydrophobic surface on enzyme stability that produces the instantaneous enzyme inactivation in many instances. However, they have recently regained some impact in enzyme immobilization. They are easy to modify, and have been prepared with different modifiers. We will pay special attention to the coating of these supports with ionic liquids, which permits to have the ionic liquid phase anchored to the solid and modulate the enzyme properties without risk of losing these expensive and potentially toxic compounds. Thus, this review will present the covalent or physical immobilization of enzymes on PSD supports, submitted to different modifications. Moreover, lipases immobilized via interfacial activation on some naked PSD supports have shown some unexpected improvement in their catalytic properties, with uses in reactions like hydrolysis, esterification or transesterification.
Power Hardware-in-the-Loop-Based Anti-Islanding Evaluation and Demonstration (2015)

The National Renewable Energy Laboratory (NREL) teamed with Southern California Edison (SCE), Clean Power Research (CPR), Quanta Technology (QT), and Electrical Distribution Design (EDD) to conduct a U.S. Department of Energy (DOE) and California Public Utility Commission (CPUC) California Solar Initiative (CSI)-funded research project investigating the impacts of integrating high-penetration levels of photovoltaics (PV) onto the California distribution grid. One topic researched in the context of high-penetration PV integration onto the distribution system is the ability of PV inverters to (1) detect islanding conditions (i.e., when the distribution system to which the PV inverter is connected becomes disconnected from the utility power connection) and (2) disconnect from the islanded system within the time specified in the performance specifications outlined in IEEE Standard 1547. This condition may cause damage to other connected equipment due to insufficient power quality (e.g., over-and under-voltages) and may also be a safety hazard to personnel that may be working on feeder sections to restore service. NREL teamed with the Florida State University (FSU) Center for Advanced Power Systems (CAPS) to investigate a new way of testing PV inverters for IEEE Standard 1547 unintentional islanding performance specifications using power hardware-in-loop (PHIL) laboratory testing techniques.
Blind MIMOME Wiretap Channel with Delayed CSIT (2014)

We study the Gaussian MIMOME wiretap channel where a transmitter wishes to communicate a confidential message to a legitimate receiver in the presence of eavesdroppers, while the eavesdroppers should not be able to decode the confidential message. Each node in the network is equipped with arbitrary number of antennas. Furthermore, channels are time varying, and there is no channel state information available at the transmitter (CSIT) with respect to eavesdroppers' channels; and transmitter only has access to delayed CSIT of the channel to the legitimate receiver. The secure degrees of freedom (SDoF) for such network has only been characterized for special cases, and is unknown in general. We completely characterize the SDoF of this network for all antenna configurations. In particular, we strictly improve the state-of-the-art achievable scheme for this network by proposing more efficient artificial noise alignment at the receivers. Furthermore, we develop a tight upper bound by utilizing 4 important inequalities that provide lower bounds on the received signal dimensions at receivers which supply delayed CSIT or no CSIT, or at a collection of receivers where some supply no CSIT. These inequalities together allow for analysis of signal dimensions in networks with asymmetric CSIT; and as a result, we present a converse proof that leads to characterization of SDoF for all possible antenna configurations.
MiSAR (2015)

While numerous hardware synchronization mechanisms have been proposed, they either no longer function or suffer great performance loss when their hardware resources are exceeded, or they add significant complexity and cost to handle such resource overflows. Additionally, prior hardware synchronization proposals focus on one type (barrier or lock) of synchronization, so several mechanisms are likely to be needed to support real applications, many of which use locks, barriers, and/or condition variables.
Advanced three‐dimensional tailored RF pulse for signal recovery in T2*‐weighted functional magnetic resonance imaging (2006)

T(2) (*)-weighted functional MR images are plagued by signal loss artifacts caused by susceptibility-induced through-plane dephasing. We present major advances to the original three-dimensional tailored RF (3DTRF) pulse method that pre-compensates the dephasing using three-dimensional selective excitation. The proposed 3DTRF pulses are designed iteratively with off-resonance incorporation and with a novel echo-volumar trajectory that frequency-encodes in z and phase-encodes in x,y. We also propose a computational scheme to accelerate the pulse design process. We demonstrate effective signal recovery in a 5-mm slice in both phantom and inferior brain, using 3DTRF pulses that are only 15.4 ms long. Compared to the original method, the new approach leads to significantly reduced pulse length and enhancement in slice selectivity. 3D images of the slice volume confirm fidelity of the excited phase pattern and slice profile.

Diazotization and Coupling Reactions of Ethyl 3-amino-1H-pyrazole-4-carboxylate;Synthesis of some Pyrazolozaines (2001)

Pyrazoloazines are extremely useful in agriculture and medicine. The main objective of this article is to synthesize some new pyrazoloazines. Ethyl 3-amino-1H-pyrazole-4-carboxylate undergoes diazotization, couples with activated methylene compounds and cyclizes to form pyrazolo[5,1-c][1,2,4]tri-azine derivatives. The title compound also reacts with -substituted cinnamonitriles to produce pyrazolo[1,5-a]pyrimidine derivatives. Structures of newly synthesized compounds are established via chemical and spectral methods.
Ranking Answers and Web Passages for Non-factoid Question Answering: Emory University at TREC LiveQA. (2015)

This paper describes a question answering system built by a team from Emory University to participate in TREC LiveQA’15 shared task. The goal of this task was to automatically answer questions posted to Yahoo! Answers community question answering website in real-time. My system combines candidates extracted from answers to similar questions previously posted to Yahoo! Answers and web passages from documents retrieved using web search. The candidates are ranked by a trained linear model and the top candidate is returned as the final answer. The ranking model is trained on question and answer (QnA) pairs from Yahoo! Answers archive using pairwise ranking criterion. Candidates are represented with a set of features, which includes statistics about candidate text, question term matches and retrieval scores, associations between question and candidate text terms and the score returned by a Long Short-Term Memory (LSTM) neural network model. Our system ranked top 5 by answer precision, and took 7th place according to the average answer score. In this paper I will describe our approach in detail, present the results and analysis of the system.

Following a request from the European Commission, the Panel on Dietetic Products, Nutrition and Allergies was asked to provide a scientific opinion on a list of health claims pursuant to Article 13 of Regulation (EC) No 1924/2006. This opinion addresses the scientific substantiation of health claims in relation to Lactobacillus rhamnosus ATCC 53103 (LGG) and “gastrointestinal health” and maintenance of tooth mineralisation. The scientific substantiation is based on the information provided by the Member States in the consolidated list of Article 13 health claims and references that EFSA has received from Member States or directly from stakeholders. The food constituent that is the subject of the health claims is L. rhamnosus ATCC 53103 (LGG). The Panel considers that L. rhamnosus ATCC 53103 (LGG) is sufficiently characterised.
High resolution inversion of seismic wavelet and reflectivity using iterative deep neural networks (2019)

In this work, we propose a deep learning based data-driven method for high resolution inversion of seismic data. The method splits the inversion into two subproblems: one inverts the seismic wavelet and the other for reflectivity. Using a partially learned approach, the proposed method simultaneously estimates the wavelet and reflectivity in an alternative way, and realized by deep neural networks (DNN). Both synthetic and field data examples clearly demonstrate the advantages of the proposed method in reducing the prediction error, ensuring the sparsity of the reflectivity and improving the lateral stability.

In-Situ RBS Channelling Studies Of Ion Implanted Semiconductors And Insulators (2011)

The experimental set‐up at the ion beam facility in Jena allows the performance of Rutherford backscattering spectrometry (RBS) in channeling configuration at any temperature between 15 K and room temperature without changing the environment or the temperature of the sample. Doing RBS channeling studies at 15 K increases the sensitivity to defects, because the influence of lattice vibrations is reduced. Thus, the very early processes of ion induced damage formation can be studied and the cross section of damage formation per ion in virgin material, P, can be determined. At 15 K ion‐beam induced damage formation itself can be investigated, because the occurrence of thermal effects can be widely excluded. In AlAs, GaN, and ZnO the cross section P measured at 15 K can be used to estimate the displacement energy for the heavier component, which is in reasonable agreement with other experiments or theoretical calculations. For a given ion species (here Ar ions) the measured cross section P exhibits a quadratic dependence P∝PSRIM2 with PSRIM being the value calculated with SRIM using established displacement energies from other sources. From these results the displacement energy of AlN can be estimated to about 40 eV. Applying the computer code DICADA to calculate the depth distribution of displaced lattice atoms from the channeling spectra, indirect information about the type of defects produced during ion implantation at 15 K can be obtained. In some materials like GaN or ZnO the results indicate the formation of extended defects most probably dislocation loops and thus suggest an athermal mobility of defect at 15 K.

Optimization of an X-band spline-profile horn for a military SATCOM terminal (2010)

As a risk mitigation exercise, a new X-band feed-pallet and feed horn for an existing military SATCOM terminal was designed. Through the use of an optimized horn design, and redesign of the feed network components, an improved design was obtained. The new feed system is more compact, has reduced weight, and is mechanically simpler than the existing feed pallet.
Effect of Digested Bacterial Cell Powder (DBCP) on Performance of Primiparous Sows and Suckling Piglets (1998)

Brevibacterium lactofermentumより調製された酵素処理菌体末(DBCP)経口投与の初産母豚および哺乳子豚に対する影響について研究した.DBCPを妊娠期に投与する事により,出生時の一腹あたりの子豚数が増加した.DBCPの投与により,糞中のEscheyichia coli数が減少し,また母豚初乳中の全タンパク質,β-ラクトグロブリン,γ-ラクトグロブリンの量が増加する傾向がみられた.これらのDBCPの効果はDBCPに含まれるペプチドグリカンの免疫賦活効果によるものと考えられた.DBCPを妊娠16日から,授乳期まで投与し,更に,哺乳期に哺乳期用飼料添加により投与した場合が離乳時の一腹あたり子豚数および体重において最も良い成績が得られた.

This paper introduces a novel dataset, called LCDMoire, which was created for the first-ever image demoireing challenge that was part of the Advances in Image Manipulation (AIM) workshop, held in conjunction with ICCV 2019. The dataset comprises 10,200 synthetically generated image pairs (consisting of an image degraded by moire and a clean ground truth image). In addition to describing the dataset and its creation, this paper also reviews the challenge tracks, competition, and results, the latter summarizing the current state-of-the-art on this dataset.
Chain‐Cleavage and hydrolysis of activated polyethylene glycol derivatives: Evidence for competitive processes (1990)

Abstract Studies have been carried out with the tosylate of the monomethyl ether of polyethylene glycol (MeO–PEG–OTs) and with low molecular weight models to assess whether the neighboring oxygen at position 3 or 6 provides the driving force for hydrolytic cleavage of these activated derivatives. Our results reveal that MeO–PEG–OTs undergoes hydrolysis by competitive pathways. Water directly displaces the tosylate group to give the original PEG alcohol and the oxygen at position 6 nucleophilically displaces the tosylate group to give a cyclic oxonium ion as an intermediate. This intermediate can react by three pathways. First, it can lead to the production of the original PEG alcohol by attack of water on a ring carbon; second, dioxane and a lower molecular weight PEG alcohol is produced by water attack at the nonring carbon next to the charged oxygen; and third dioxane can be displaced by the oxygen atom at position 6 in the chain.
Analysis and Characterization of Aromatic Polyamide Copolymer Particles with Trifluoromethyl and Amino Groups (2011)

Nano-sized aromatic polyamide copolymer particles with trifluoromethyl (CF3) and amino (NH2) groups were prepared by copolymerizing 4,4′-diphenyldicarbonyl chloride (DPE) with 2,2-bis(4-aminophenyl) hexafluoropropane (BAHFP) and bis(3,4-diaminophenyl) ether (BDAPE). They were spherical particles with diameters of 150–320 nm. The diameter varied depending on the monomer ratio. The copolymer compositions of the products were characterized by FT-IR and Thermogravimetric analysis (TGA) measurements and found to be in close agreement with the monomer ratios. In addition, all of the products containing BDAPE were found to have a partially cross-linked structure. The amount of CF3 and NH2 groups attached to the particles changed depending on the monomer ratio.
