Detection and quantification of phytotoxic metabolites of Sarocladium oryzae in sheath rot-infected grains of rice (2002)

Antimicrobial and phytotoxic metabolites, helvolic acid and cerulenin are present in infected grains and reduce the seed viability and seedling health. These metabolites may increase the pathogenic potential and survival of S. oryzae in rice seed by competing with other seed-borne fungi.
Brain Tissues Segmentation on MR Perfusion Images Using CUSUM Filter for Boundary Pixels (2019)

The fully automated and relatively accurate method of brain tissues segmentation on T2-weighted magnetic resonance perfusion images is proposed. Segmentation with this method provides a possibility to obtain perfusion region of interest on images with abnormal brain anatomy that is very important for perfusion analysis. In the proposed method the result is presented as a binary mask, which marks two regions: brain tissues pixels with unity values and skull, extracranial soft tissue and background pixels with zero values. The binary mask is produced based on the location of boundary between two studied regions. Each boundary point is detected with CUSUM filter as a change point for iteratively accumulated points at time of moving on a sinusoidal-like path along the boundary from one region to another. The evaluation results for 20 clinical cases showed that proposed segmentation method could significantly reduce the time and efforts required to obtain desirable results for perfusion region of interest detection on T2-weighted magnetic resonance perfusion images with abnormal brain anatomy.
λ Vectors for Stable Cloned Gene Expression (1990)

The bacteriophage lambda offers a unique opportunity concurrently to minimize segregational instability in recombinant systems by chromosomal integration of the cloned gene and to achieve high cloned gene expression during an abortive lytic phase. Lysis leads approximately to a 100-fold amplification of the cloned gene. Cell lysis in the lytic state is blocked by a specific mutation (Sam), allowing the cell to maintain its integrity, and lambda DNA packaging is blocked by other mutations (Wam, Eam) that keep cloned genes open to transcription. In the presence of these mutations, extremely high levels of cloned beta-galactosidase (more than 15% of total cell protein) have been obtained during abortive lysis from vectors found to be essentially 100% stable for over 75 generations in the lysogenic phase.
pnCCDs for Ultra-Fast and Ultra-Sensitive Optical and NIR Imaging (2008)

We present the design, status of fabrication and testing, and expected performance characteristics of new CCDs for highest frame rates and excellent sensitivity over a wide wavelength range, from the near UV to the to near IR. To achieve frame rates in the kHz regime, the devices are based on proven technology with column parallel readout. The CCDs are back illuminated, sensitive over their full thickness of 450 μm, allowing a peak quantum efficiency near 100% at any chosen wavelength between 400 nm and 1,000 nm. Test results, including astronomical trials at Skinakas observatory, using available devices with an on‐chip JFET amplifier are presented. Based on the above CCD design we are currently producing two novel variants with single photon counting capabilities: They either use integrated avalanche diodes in the readout chain or a repetitive non‐destructive readout. Both readout schemes have already successfully proven their single‐photon sensitivity and we present the related results.
Photoinduced electron transfer from rail to rung within a self-assembled oligomeric porphyrin ladder (2009)

Photoinduced electron transfer in a self-assembled supramolecular ladder structure comprising oligomeric porphyrin rails and ligated dipyridyltetrazine rungs was characterized by transient absorption spectroscopy and transient direct current photoconductivity to be mainly from an oligomer (rail) to the center of a terminal tetrazine (rung), with the remaining hole being delocalized on the oligomer and subsequent charge recombination in 0.19 ns.
Divergent Coupling of Alcohols and Amines Catalyzed by Isoelectronic Hydride MnI and FeII PNP Pincer Complexes (2016)

Herein, we describe an efficient coupling of alcohols and amines catalyzed by well-defined isoelectronic hydride Mn(I) and Fe(II) complexes, which are stabilized by a PNP ligand based on the 2,6-diaminopyridine scaffold. This reaction is an environmentally benign process implementing inexpensive, earth-abundant non-precious metal catalysts, and is based on the acceptorless alcohol dehydrogenation concept. A range of alcohols and amines including both aromatic and aliphatic substrates were efficiently converted in good to excellent isolated yields. Although in the case of Mn selectively imines were obtained, with Fe-exclusively monoalkylated amines were formed. These reactions proceed under base-free conditions and required the addition of molecular sieves.
Quotients of orders in cyclic algebras and space-time codes (2013)

Let $F$ be a number field with ring of integers $\boldsymbol{O}_F$ and $D$ a division $F$-algebra with a maximal cyclic subfield $K$. We study rings occurring as quotients of a natural $\boldsymbol{O}_F$-order $\Lambda$ in $D$ by two-sided ideals. We reduce the problem to studying the ideal structure of $\Lambda/q^s\Lambda$, where $q$ is a prime ideal in $\boldsymbol{O}_F$, $s\geq 1$. We study the case where $q$ remains unramified in $K$, both when $s=1$ and $s>1$. This work is motivated by its applications to space-time coded modulation.
1 Membrane Biofilm Reactors for Water and Wastewater Treatment (2015)

Certain gaseous substrates, such as hydrogen, methane, and oxygen, can act as electron donor or acceptors for desired microbial processes. These gases are inexpensive and can lead to effective processes, but their low water solubility can limit their use. The membrane biofilm reactor (MBfR) is a novel system that uses membranes to supply dissolved gas directly to a biofilm growing on the membrane surface. This paper describes the MBfR and discusses applications for water and wastewater treatment.

p-(Methanesulfonyl) styrene-linked cyclic ketone derivatives showed strong anti-inflammatory activity but few GI side effects and deserve to be further investigated.
Excitation and Measurement of BSR in Vehicle Seats (2001)

&lt;div class="htmlview paragraph"&gt;Buzz, Squeak, and Rattle (BSR) tests are commonly employed in the automotive industry as a diagnostic. The resulting signals are typically analyzed using established (historical) metrics such as A-weighted SPL or stationary loudness (ISO532B). However, due to the non-stationary nature of these signals, traditional metrics often fail to fully describe the signals in question. Compounding the issue is the fact that some specifications state that the test specimen is to produce ‘no objectionable noises’ when subjected to representative excitation. This is a very vague and debatable statement that normally cannot be settled by subjective observations alone. Within this paper, sound quality and statistical metrics are employed for several BSR signals acquired during forced response testing of a seat. Results are presented for two different boundary conditions and alternative signal processing tools are presented. Signal processing of non-stationary signals for an unoccupied and biofidelic mannequin-loaded seat are presented and compared.&lt;/div&gt;

Mechanisms behind the Faceting of Catanionic Vesicles by Polycations:  Chain Crystallization and Segregation (2006)

Vesicles composed of an anionic and a cationic surfactant, with a net negative charge, associate strongly with a hydrophobically modified polycation (LM200) and with an unmodified polycation with higher charge density (JR400), forming viscoelastic gel-like structures. Calorimetric results show that in these gels, LM200 induces a rise of the chain melting temperature (Tm) of the vesicles, whereas JR400 has the opposite effect. For both polymer-vesicle systems, the shear viscosity exhibits an inflection point at Tm, and for the LM200 system the measured relaxation times are significantly higher below Tm. The neat vesicles and the polycation-bound vesicles have a polygonal-like faceted shape when the surfactant chains in the bilayer are crystallized, as probed by cryo-transmission electron microscopy. Above Tm, the neat and the LM200-bound vesicles regain a spheroidal shape, whereas those in the JR400 system remain with a deformed faceted shape even above Tm. These shape changes are interpreted in terms of different mechanisms for the polymer-vesicle interaction, which seem to be highly dependent on polymer architecture, namely charge density and hydrophobic modification. A crystallization-segregation mechanism is proposed for the LM200-vesicle system, while, for the JR400-vesicle one, charge polarization-lateral segregation effects induced by the polycation in the catanionic bilayer are envisaged.
Hamiltonian Simulation in the Interaction Picture (2018)

We present a low-space overhead simulation algorithm based on the truncated Dyson series for time-dependent quantum dynamics. This algorithm is applied to simulating time-independent Hamiltonians by transitioning to the interaction picture, where some portions are made time-dependent. This can provide a favorable complexity trade-off as the algorithm scales exponentially better with derivatives of the time-dependent component than the original Hamiltonian. We show that this leads to an exponential improvement in gate complexity for simulating some classes of diagonally dominant Hamiltonian. Additionally we show that this can reduce the gate-complexity scaling for simulating $N$-site Hubbard models for time $t$ with arbitrary long-range interactions as well as reduce the cost of quantum chemistry simulations within a similar-sized plane-wave basis to $\widetilde{\mathcal{O}}(N^2t)$ from $\widetilde{\mathcal{O}}(N^{11/3}t)$. We also show a quadratic improvement in query complexity for simulating sparse time-dependent Hamiltonians, which may be of independent interest.

EFFECTS OF GRADIENT MAGNETIC FIELD ON THE SOLIDIFICATION STRUCTURE OF ALUMINUM UNDER ELECTROMAGNETIC VIBRATION (2007)

The effect of gradient high magnetic field on the structure refinement of pure A1 has been investigated experimentally.It was found that during electromagnetic vibration the refining region was influenced by the magnetization force and gravity.A model responsible for the magnetization force-restrain migratation of crystal grains has been proposed based on the classical dynamics,in which the grain is treated as a spheroid.A theoretical expression was derived for the migratation of grain as a function of applied magnetic intensity and gradient.The micro-gravitational solidification and restraint ofcrystal showercan be realized under gradient high magnetic field.
Simple technique for measuring cavity lossin semiconductor lasers (1994)

A new technique for measuring the cavity loss of semiconductor lasers is introduced. The cavity loss is deduced from the Fabry-Perot oscillations in the spontaneous emission well below the bandgap of the active region. This approach, referred to as the below-bandgap technique, is simple, applicable to both Fabry-Perot and DFB lasers, and is capable of measuring cavity losses with few restrictions on laser bias current.
Insecticides for Suppression of Nylanderia fulva (2017)

<i>Nylanderia fulva</i> (Mayr) is an invasive ant that is a serious pest in the southern United States. Pest control operators and homeowners are challenged to manage pest populations below acceptable thresholds. Contact and bait insecticides are key components of an Integrated Pest Management (IPM) strategy, however, little is known about their efficacy. In repellency and efficacy bioassays, <i>N. fulva</i> were not completely repelled by any insecticide tested, although fewer ants crossed a surface treated with Temprid<sup>®</sup>. Few insecticides provided rapid control. Termidor<sup>®</sup> and Temprid<sup>®</sup> were the best performing with mean mortality of 100% in 13.4 and 19.0 days, respectively. In no-choice bait acceptance studies, it was shown that <i>N. fulva</i> generally had greater acceptance of carbohydrate-based ant baits (Advion<sup>®</sup>, InTice<sup>TM</sup> (gel), and InTice<sup>TM</sup> (granular)). However, mortality was low for the InTice<sup>TM</sup> baits in a 7-day bioassay. Maxforce<sup>®</sup> Ant Killer Bait Gel and Advance<sup>®</sup> 375A in the spring and Maxforce<sup>®</sup> Complete in the summer and fall required the fewest days to reach 100% mortality. Bait active ingredients that resulted in the highest mortality were hydramethylnon and fipronil. These data on the efficacy of commercially available contact and bait insecticides provide valuable information to manage this invasive pest.

Differential Diagnosis of Left Ventricular Mural Thrombi by Myocardial Contrast Echocardiography (1999)

Two-dimensional echocardiography has become the procedure of choice to diagnose left ventricular mural thrombi. However, small or flat thrombi may be difficult to distinguish from myocardium. The spatial distribution of the ventricular myocardial blood flow can be imaged with myocardial contrast echocardiography (MCE). The authors presumed that the absence of arterial supply to a fresh thrombus may allow MCE to distinguish between thrombus and myocardium. In the 2 cases presented here, MCE was performed with the same technique as that used for the purpose of visualization of myocardial perfusion; as a result, an apical mural thrombus, indistinct from myocardium before MCE, was visualized as a contrast defect during imaging. Conversely, myocardium that mimicked a thrombus was imaged by MCE as a contrast-opacified area. These findings suggest that MCE after reperfusion therapy is useful to distinguish mural thrombi from myocardium.
Right Ventricular Pressure, dP/dt, and Preejection Interval During Tilt Induced Vasovagal Syncope (1997)

This study examined the potential utility of monitoring right ventricular dP/dt as a means of detecting imminent vasovagal syncope. To assess this possibility, continuous right ventricular pressure measurements were recorded in nine patients during induction of syncope by head-up tilt testing. Findings indicated that arterial pressure tended to fall prior to drop in heart rate. RV pressure exhibited a significant, but very small, fall during tilt. DP/dt max increased by 15-20% during tilt, then fell by a median of 30% from maximum value beginning about 2 minutes prior to syncope. Thus, further investigation of dP/dt as a potential marker of impending vasovagal syncope is warranted.
Evaluation of a Community Bicycle Helmet Promotion Campaign: What Works and Why (1993)

Future helmet campaigns should use interpersonal strategies to increase parental worry about their children being involved in a bicycle accident. Generalization of these findings is limited by the high socioeconomic status of the study participants, and by the outcome measure, which is helmet ownership, not helmet use.
Molecular Sciences Made Personal: Developing Curiosity in General and Organic Chemistry with a Multi-Semester Utility Value Intervention (2019)

Freshmen and sophomores in college are historically at risk of disengaging with general and organic chemistry courses, performing poorly and not continuing in STEM. Utility value (UV) interventions, though, have increased the achievement and retention of low-performing students in psychology and introductory biology courses. In this study, a multi-semester UV intervention is being implemented to increase curiosity, a predictor of increased learning and retention, of three student cohorts going through general and organic chemistry. In General Chemistry II, student groups complete a research project applying abstract chemistry concepts, such as acid base properties, to clinically prescribed drugs, considering inter-individual variations based on personal genetics. In Organic Chemistry I, students complete a series of short journal prompts connecting organic chemistry with nutrition. Based on a preliminary analysis of cohort 1 and 2, students exposed to the multi-semester intervention perform a half letter grade better in introductory biochemistry after controlling for their ACT Composite and Math scores. Based on cohort 1’s self-reported evaluations at the end of Organic Chemistry 2, a significant (p = .003) increase in curiosity occurred with the intervention group students (N = 42) compared to the control students (N = 167). A focus group of intervention participants who had recently completed Introductory Biochemistry indicated these students believed the intervention had better prepared them for biochemistry. These preliminary findings suggest the multi-semester UV intervention increases student engagement in introductory chemistry and increases students’ self-confidence in applying independent scientific thinking and higher-order problem-solving skills, particularly during the culminating biochemistry course.

Análise teórica da atuação de canabinoides nas vias metabólicas do câncer de mama por meio da biologia de sistemas e revisão sistemática da literatura (2021)

Entre as mulheres, o câncer de mama é o mais comum e incidente tipo de tumor. Apesar dos avanços significativos no tratamento, permanecem lacunas em relação ao entendimento dos mecanismos de resistência às terapias. Os canabinoides têm demonstrado significativa atuação no tratamento de tumores mamários, tanto em culturas celulares como em modelos vivos. Dado o perfil heterogêneo deste tipo de tumor e a complexidade do potencial terapêutico dos canabinoides, é necessária a identificação de vias metabólicas de atuação destes compostos, para a elaboração de medicamentos no combate a doenças como o câncer de mama. Neste trabalho, buscou-se, por meio de uma Revisão Sistemática da Literatura e dados obtidos na base de dados StringDB, explanar o papel de atuação do canabinoide canabidiol em células MDA-MB-231 de câncer de mama. Identificou-se que a clássica via de sinalização JAK-STAT pode ser uma via crucial para a atuação do canabidiol no câncer de mama, tendo em vista que a proteína STAT3 pode ser ativada por receptores acoplados a proteína G, que são alvos de modulação alostérica negativa do canabidiol. Conclui-se que o efeito do canabidiol em seus respectivos receptores pode promover a modulação dos mesmos e consequentemente a não ativação de STAT3.
Hyperbranched Poly(ethylene glycol)s:  A New Class of Ion-Conducting Materials (1996)

A new concept for the synthesis of hyperbranched macromolecules involving the use of ABx macromonomers containing linear oligomeric units is introduced. This methodology is used for the preparation of a series of novel hyperbranched poly(ethylene glycol) derivatives containing linear poly(ethylene glycol) units of varying lengths and 3,5-dioxybenzoate branching units. An interesting feature of the hyperbranched poly(ethylene glycol) derivatives is their lack of crystallinity, which is used in the design of a new class of polyelectrolyte materials. The dependence of the ionic conductivity on temperature and the concentration of added lithium cations for these novel hyperbranched macromolecules is reported.

A Survey on Intrusion Detection Systems for Cloud Computing Environment (2015)

Cloud Computing is a newly emerged technology. It is getting popularity day by day due to its amazing services. The applications and services based on the cloud are emerging day by day. Due to networked nature of the cloud, resources, data and applications are vulnerable to the attack in cloud environment. So Intrusion Detection Systems (IDS) are employed in the cloud to detect malicious behaviour in the network and in the host. IDS monitors network or host system activities by collecting network information, and analyzes this information for malicious activities and generate alarms, if intrusion takes place. In this paper we surveyed various types of Intrusion Detection Systems proposed over the years for Cloud Computing environment.
Acetazolamide-induced cerebral and ocular vasodilation in humans is independent of nitric oxide (1999)

Acetazolamide, a carbonic anhydrase inhibitor, is used orally in the treatment of primary and secondary open-angle glaucoma and induces ocular and cerebral vasodilation. Several in vitro studies have shown that carbonic anhydrase pharmacology and the L-arginine-nitric oxide (NO) pathway are closely related. We investigated the role of NO in acetazolamide-induced vasodilation on cerebral and ocular vessels in 12 healthy subjects in the presence or absence of NG-monomethyl-L-arginine (L-NMMA), a NO synthase inhibitor, and in the presence or absence of L-arginine, the precursor of NO. Acetazolamide was administered after pretreatment with either L-NMMA or placebo and either L-arginine or placebo. Pulsatile choroidal blood flow was assessed with laser interferometric measurement of fundus pulsation. In addition, mean blood flow velocity (MFV) in the middle cerebral artery (MCA) and ophthalmic artery (OA) was measured with Doppler sonography. Acetazolamide increased ocular fundus pulsation amplitude (FPA; +27%, P < 0.001) and MFV in the MCA (+38%, P < 0.001) and in the OA (+19%, P = 0.003). Administration of L-NMMA alone reduced FPA (-21%, P < 0.001) and MFV in the MCA (-11%, P = 0. 030) but did not change MFV in the OA. All hemodynamic effects of L-NMMA were reversed by L-arginine. However, neither L-NMMA nor L-arginine altered acetazolamide-induced changes in cerebral or ocular hemodynamic parameters. The present data indicate that acetazolamide-induced hemodynamic changes are not mediated by NO. Which mediators other than NO are involved in the hemodynamic effects as induced by carbonic anhydrase inhibitors remains to be elucidated.
