Endophytic Fungi from Frankincense Tree Improves Host Growth and Produces Extracellular Enzymes and Indole Acetic Acid (2016)

Boswellia sacra, an economically important frankincense-producing tree found in the desert woodlands of Oman, is least known for its endophytic fungal diversity and the potential of these fungi to produce extracellular enzymes and auxins. We isolated various fungal endophytes belonging to Eurotiales (11.8%), Chaetomiaceae (17.6%), Incertae sadis (29.5%), Aureobasidiaceae (17.6%), Nectriaceae (5.9%) and Sporomiaceae (17.6%) from the phylloplane (leaf) and caulosphere (stem) of the tree. Endophytes were identified using genomic DNA extraction, PCR amplification and sequencing the internal transcribed spacer regions, whereas a detailed phylogenetic analysis of the same gene fragment was made with homologous sequences. The endophytic colonization rate was significantly higher in the leaf (5.33%) than the stem (0.262%). The Shannon-Weiner diversity index was H' 0.8729, while Simpson index was higher in the leaf (0.583) than in the stem (0.416). Regarding the endophytic fungi's potential for extracellular enzyme production, fluorogenic 4-methylumbelliferone standards and substrates were used to determine the presence of cellulases, phosphatases and glucosidases in the pure culture. Among fungal strains, Penicillum citrinum BSL17 showed significantly higher amounts of glucosidases (62.15±1.8 μM-1min-1mL) and cellulases (62.11±1.6 μM-1min-1mL), whereas Preussia sp. BSL10 showed significantly higher secretion of glucosidases (69.4±0.79 μM-1min-1mL) and phosphatases (3.46±0.31μM-1min-1mL) compared to other strains. Aureobasidium sp. BSS6 and Preussia sp. BSL10 showed significantly higher potential for indole acetic acid production (tryptophan-dependent and independent pathways). Preussia sp. BSL10 was applied to the host B. sacra tree saplings, which exhibited significant improvements in plant growth parameters and accumulation of photosynthetic pigments. The current study concluded that endophytic microbial resources producing extracellular enzymes and auxin could establish a unique niche for ecological adaptation during symbiosis with the host Frankincense tree.
Neural network based controller for constrained multivariable systems (2010)

This paper presents a new neural network based controller design for multivariable systems. The proposed controller is designed using radial basis function (RBF) neural network. Weight update equation using classical least mean square principle is derived for the RBF network. The controller generates optimal control signals abiding by constraints, if any, on the control signals. Simulation results are included in the end to assess the performance of the proposed controller.
Leisure Sports, Leisure Satisfaction and Happiness in Single-Elderly Female Households (2018)

The purpose of this study is to examine the relationships among physical leisure activity, leisure satisfaction, and happiness in 442 single females aged 60-89. The data analyezd was from a 2016 National Leisure Activity Survey. (920 female women in households of two or more served as the comparison group.) In this study, a status analysis, one-way ANOVA, Pearson’s R were conducted to explore their leisure life and the levels of leisure satisfaction and happiness. First, the results of the study showed that single, elderly female households had lower levels of leisure satisfaction and happiness than the comparison group. Second, as for participation in sports-leisure activities experienced in a year, the group of single, elderly female households was lower than the comparison group. Third, in the single-older female househlods group, participants who chose physical leisure activities as their main leisure activity had higher lveels of leisure satisfaction and happiness than participants who chose watching TV and walking. Fourth, regardingh appiness, it was positively highly correlated with leisure satisfaction while leisure cost and monthly average household income was not. To improve health related quality of life in elderly Korean women living alone, these results show that physical leisure activities are recommended. There should be more opportunities for sports participation and the participation should be started earlier. Furthermore, psychological aspects that might inhibit physical activities, such as a fear of starting something new, should be considered in future national leisure services and policies.
Management of Low-Grade Third Ventricular Ependymomas in Adults by Endoscopic Biopsy Followed by Gamma Knife Radiosurgery (2013)

The strategy of endoscopic biopsy followed by gamma knife radiosurgery for adult WHO grade II third ventricular ependymomas has produced acceptable clinical results 3 years posttreatment. Stereotactic radiosurgery without prior microsurgical resection has not previously been reported in these tumors. Longer follow-up is required to evaluate the durability of this treatment.
Structured Sensing Matrix Design for In-sector Compressed mmWave Channel Estimation (2022)

Fast millimeter wave (mmWave) channel estimation techniques based on compressed sensing (CS) suffer from low signal-to-noise ratio (SNR) in the channel measurements, due to the use of wide beams. To address this problem, we develop an in-sector CS-based mmWave channel estimation technique that focuses energy on a sector in the angle domain. Specifically, we construct a new class of structured CS matrices to estimate the channel within the sector of interest. To this end, we first determine an optimal sampling pattern when the number of measurements is equal to the sector dimension and then use its subsampled version in the sub-Nyquist regime. Our approach results in low aliasing artifacts in the sector of interest and better channel estimates than benchmark algorithms.

The r33 electro-optic coefficient of Er:LiNbO3 (2009)

By exploiting a Mach-Zehnder interferometer, the r(33) electro-optic coefficient of erbium-bulk-doped lithium niobate crystals grown by the Czochralski technique was measured depending on the erbium content. The r(33) coefficient decreases with the erbium concentration. Such a trend has been connected with both the reduction of the lattice parameter, measured by high resolution x-ray diffraction, and the increase of lattice defects.
[Extrapleural pneumonectomy after hyperthermo-chemotherapy for the lung cancer patients with malignant pleural effusion]. (2004)

The prognosis of the lung cancer patients with malignant pleural effusion is extremely poor. Intrapleural perfusion hyperthermo-chemotherapy for the treatment of malignant pleural effusion was performed in 120 lung cancer patients and showed better prognosis than conventional treatment. After successful local control by hyperthermo-chemotherapy, extrapleural pneumonectomy was performed in 8 patients with clinical N 0 or N 1 and M 0 lung cancer. All patients survived for more than 1 year. The only 1 patient survived for more than 3 years and 3 months without recurrence. Almost all patients who died within 2 years had pathological n 2, carcinomatous pericarditis, cancer invasion beyond extrapleural space and so on. Extrapleural pneumonectomy after hyperthermo-chemotherapy can be a choice of surgical treatment if the n 2 disease, pericarditis, and extrapleural invasion of disseminated cancer cells should be excluded precisely.
Long‐term efficacy and safety of combined insulin and glucagon‐like peptide‐1 therapy: Evidence from the LEADER trial (2019)

In patients on insulin, liraglutide improved glycaemic control, weight and need for insulin versus placebo, for at least 36 months with no increased risk of severe hypoglycaemia, while maintaining CV safety/efficacy, supporting the combination of liraglutide and insulin for management of type 2 diabetes.
Oscillations in intrinsic photoconductivity and photo-hall effect spectra of n-type CdTe (1973)

The oscillatory structure of the intrinsic photoconductivity responseof n-type CdTe samples was observed. The photoresponse to chopped light shows a phase delay, which oscillates with photon energy. Also the photo-Hall effect was investigated. For these quantities a phenomenological theory is developed which takes into account the variations of the mobility and lifetime of electrons according to their position in thecrystal (non-uniform excitation). From this the dependence of the mobility of electrons in the lightexcitated part of the sample versus wavelength is deduced. Also this spectrum has an oscillatory structure. An explanation is proposed of all these results: the annihilation, by Auger effect, of an exciton bound to a neutral donor produces variations in mobility and lifetime of electrons. Nous avons observé la structure oscillatoire des spectres dephotoconductivité dans des échantillons de CdTe de type n. Le déphasage du photo-signal par rapport au faisceau lumineux modulé présente des oscillations spectrales. Nous avons aussi mesuré la tension d'effet photo-Hall. Pour évaluer ces quantités, nous avons développé une théorie phénoménologique qui tient compte des variations de la mobilité et de la durée de vie des électrons suivant leur position dans le cristal (excitation non homogène). A partir de cela nous pouvons déduire la dépendance spectrale de la mobilité des électrons dans la région de l'échantillon excitée par la lumière. Ce spectrea lui aussi une structure oscillatoire. Nous proposons une explication detous ces résultats: l'annihilation, par effet Auger, d'un exciton lié a un donneur neutre provoque des variations de la mobilité et de la durée de vie des électrons.
Advanced curved planar reformation: flattening of vascular structures (2004)

Traditional volume visualization techniques may provide incomplete clinical information needed for applications in medical visualization. In the area of vascular visualization important features such as the lumen of a diseased vessel segment may not be visible. Curved planar reformation (CPR) has proven to be an acceptable practical solution. Existing CPR techniques, however, still have diagnostically relevant limitations. In this paper, we introduce two advances methods for efficient vessel visualization, based on the concept of CPR. Both methods benefit from relaxation of spatial coherence in favor of improved feature perception. We present a new technique to visualize the interior of a vessel in a single image. A vessel is resampled along a spiral around its central axis. The helical spiral depicts the vessel volume. Furthermore, a method to display an entire vascular tree without mutually occluding vessels is presented. Minimal rotations at the bifurcations avoid occlusions. For each viewing direction the entire vessel structure is visible.
Hückel Molecular Orbital Calculation of p-Substituted Styrene Derivatives (1967)

ヒュケル型の分子軌道の計算によって種々のp-置換スチレンのπ-電子準位を求めた。置換基とべンゼン核間のクーロン積分,共鳴積分の補正パラメータとして a およびlを用いた。パラメータaは最高被占準位と最低空準位間のエネルギー差が測定された最低のπ-電子励起エネルギーに等しくなるように定め,パラメータlはStreitwieserの提案した値を採用した。このようにして求めた最高被占準位がイオン化電圧に相当するものとみなし,種々のp-置換スチレンのイオン化電圧を算出した。このようにして算出した値と電荷移動エネルギーから求めたイオン化電圧とよく一致した。また,分子軌道の計算結果を基礎として,親電子試薬に対するフロンティア電子密度を求め,この種のp-置換スチレンの重合反応の機作との関連に推論をこころみた。

Calcium signaling in systemic lupus erythematosus T cells: A treatment target (2011)

NF-AT activation is a key step in the activation of SLE T cells and the production of immunoglobulin. Dipyridamole inhibits SLE T cell function and improves pathologic changes of the disease in lupus-prone mice. We propose that dipyridamole can be used in treatment regimens for patients with SLE.
Opto-mechanical lab-on-fibre seismic sensors detected the Norcia earthquake (2018)

We have designed and developed lab-on-fibre seismic sensors containing a micro-opto-mechanical cavity on the fibre tip. The mechanical cavity is designed as a double cantilever suspended on the fibre end facet and connected to a proof mass to tune its response. Ground acceleration leads to displacement of the cavity length, which in turn can be remotely detected using an interferometric interrogation technique. After the sensors characterization, an experimental validation was conducted at the Italian National Institute of Geophysics and Volcanology (INGV), which is responsible for seismic surveillance over the Italian country. The fabricated sensors have been continuously used for long periods to demonstrate their effectiveness as seismic accelerometer sensors. During the tests, fibre optic seismic accelerometers clearly detected the seismic sequence that culminated in the severe Mw6.5 Norcia earthquake that struck central Italy on October 30, 2016. The seismic data provided by the optical sensors were analysed by specialists at the INGV. The wave traces were compared with state-of-the-art traditional sensors typically incorporated into the INGV seismic networks. The comparison verifies the high fidelity of the optical sensors in seismic wave detection, indicating their suitability for a novel class of seismic sensors to be employed in practical scenarios.

Manifold Mixup: Encouraging Meaningful On-Manifold Interpolation as a Regularizer. (2018)

Deep networks often perform well on the data manifold on which they are trained, yet give incorrect (and often very confident) answers when evaluated on points from off of the training distribution. This is exemplified by the adversarial examples phenomenon but can also be seen in terms of model generalization and domain shift. We propose Manifold Mixup which encourages the network to produce more reasonable and less confident predictions at points with combinations of attributes not seen in the training set. This is accomplished by training on convex combinations of the hidden state representations of data samples. Using this method, we demonstrate improved semi-supervised learning, learning with limited labeled data, and robustness to adversarial examples. Manifold Mixup requires no (significant) additional computation. Analytical experiments on both real data and synthetic data directly support our hypothesis for why the Manifold Mixup method improves results.

Probing the explanation of the muon (g-2) anomaly and thermal light dark matter with the semi-visible dark photon channel (2021)

We report the results of a search for a new vector boson ($A'$) decaying into two dark matter particles $\chi_1 \chi_2$ of different mass. The heavier $\chi_2$ particle subsequently decays to $\chi_1$ and $A' \to e^- e^+$. For a sufficiently large mass splitting, this model can explain in terms of new physics the recently confirmed discrepancy observed in the muon anomalous magnetic moment at Fermilab. Remarkably, it also predicts the observed yield of thermal dark matter relic abundance. A detailed Monte-Carlo simulation was used to determine the signal yield and detection efficiency for this channel in the NA64 setup. The results were obtained re-analyzing the previous NA64 searches for an invisible decay $A'\to \chi \overline{\chi}$ and axion-like or pseudo-scalar particles $a \to \gamma \gamma$. With this method, we exclude a significant portion of the parameter space justifying the muon g-2 anomaly and being compatible with the observed dark matter relic density for $A'$ masses from 2$m_e$ up to 390 MeV and mixing parameter $\epsilon$ between $3\times10^{-5}$ and $2\times10^{-2}$.
Practical Approaches to Analyzing Results of Microarray Experiments (2002)

Microarray technology is rapidly becoming a standard laboratory technique. The main challenges related to the successful implementation of the technology are analysis-related. In this article we provide a practically oriented review focusing on methods for analysis of large-scale gene expression data in the research laboratory. We describe the various common clustering methods and outline our approach to using them. We discuss methods for scoring genes for their relevance, focusing on the statistical meaning of microarray results, especially with regard to the problem of multiple testing. We also deal with the problem of adding biologic meaning to the results of microarray experiments and describe advanced tools that represent different but valid directions in providing automated solutions to this problem. The tools and approaches described and discussed here should provide the reader with a preliminary understanding of the analysis of the results of microarray experiments. The practical focus of this review should remove the mystery behind the analysis of microarray experiments, thus leading to more productive and efficient use of the technology.

Hydrolysis of oligoribonucleotides: influence of sequence and length (1992)

The chemical stability of phosphodiester bonds of some oligoribonucleotides in the presence of a cofactor like polyvinylpyrolidine (PVP) is sequence dependent. It was found that pyrimidine-A (YA) and pyrimidine-C (YC) are especially susceptible to hydrolysis. The hydrolyzability of this same phosphodiester bond is dependent on its position in the oligomer. The presence of 3' and 5'-adjacent nucleotides enhances hydrolysis of the UA phosphodiester bond. The acceleration of the hydrolysis of UA by a 5'-adjacent nucleotide is not base dependent. However, a 3'-adjacent purine increases hydrolysis of a UA phosphodiester bond more than a 3'-pyrimidine. The presence of the exoamino group on the 3'-side base (on 6 and 4 position for adenosine and cytidine, respectively) of YA or YZ phosphodiester bond is required for hydrolysis.
Experimental verification of motion mitigation of discrete proton spot scanning by re-scanning (2013)

In order to be able to treat mobile tumours with active, scanned proton therapy, adequate motion mitigation techniques have to be applied. Re-scanning is such an approach, where the interplay effect between tumour motion and treatment delivery is statistically smeared out. Different re-scanning methods have been used for the irradiation of a spherical target volume and motion amplitudes of up to 10 mm. The resulting dose distributions have been captured in two dimensions by imaging a scintillating screen at the iso-centre for different motion starting phases. Dose inhomogeneity increased approximately linearly with motion amplitude, while the influence of motion period and direction was small. Re-scanning the whole target volume reduced the interplay effect more than re-scanning only the iso-energy layers. Even for 10 mm motion amplitude, no hot or cold spots were seen for 10 re-scans of the whole volume. A fast energy change and fast beam scanning is vital for this kind of re-scanning, as available on Gantry 2 at the Paul Scherrer Institute. For larger motion amplitudes, re-scanning should be combined with gating, breath-hold or tracking to reduce the internal target volume.
Role of natural products in belowground interactions between plant species (2019)

Plants are consistently releasing root exudates into the rhizosphere which have the potential to influence the growth and development of neighboring plant species. Root exudates contain low and high molecular weight compounds such as sugars, amino acids, secondary metabolites, phytohormones, proteins, enzymes, and polysaccharides. Although aboveground plant interactions through volatile compounds has been extensively studied, only few studies investigated role of the belowground chemical interactions between plant species. The aim of this study is to elucidate the belowground chemical interactions between rye and hairy vetch grown together as cover crop mixture. Rye and hairy vetch were cultivated alone and together in pots filled with micro glasssbeads. Plant were grown for three weeks in climate chamber and their root exudates were collected for the chemical analysis. Targeted analysis with LC-MS/MS was done to identify the changes occurring in secondary metabolite profile of the rye and hairy vetch’s root exudates as result of co-cultivation. Quantification results displayed that both hairy vetch and rye are altering their root exudation in response to rye-hairy vetch co cultivation. Hairy vetch significantly increased concentration of root exuded flavonoids such as kaempferol and pratensein in response to presence of rye. Concentrations of DIMBOA (2,4-dihydroxy-7-methoxy-1,4-benzoxazin-3-one) and BOA (1,3-benzoxazol-2-one) in rye’s root exudate were increased significantly as result of co cultivation with hairy vetch. The results from this study will increase our understanding about root exuded natural products with growth suppressive effects, which finally leads us to more sustainable plant protection system.<br/>
