description: 16. B. ruderarius (Müller, 1776) Flugzeiten: alte ♀♀ 7. 4. — 3. 8., ♀♀ 1. 6. — 10. 9., ♂ ♂ 1. 7. bis 13. 9. — Bevorzugte Blüten: Calluna vulgaris, Empetrum nigrum, Vicia cracca. — In ganz Deutschland nicht selten. Für Cuxhaven wird diese Art erstmals von A. C. W. Wagner (1914) verzeichnet. Ausserdem wer­ den von Alfken und A. C. W. Wagner (1914) die Fundorte Ahrensch und Oxstedt vermerkt. 1937 nennt A. C. W. Wagner 120 Fundorte. Demnach war. ruderarius von 1913—37 hier nicht nur heimisch, sondern vielleicht auch häufig. Von 1959—6 und 1968—69 konnten im untersuchten Gebiet insgesamt 165 Individuen gefangen werden, d. s. 2,3% aller zur Verfügung stehenden Hummeln. Er wurde vornehmlich in den unbebauten Geest­ gebieten I und II nachgewiesen. Ein Vergleich der Befunde von 1959—6 mit denen von 1968—69 mag darauf hindeuten, dass auch diese Art im Raum Cuxhaven immer seltener wird. Die besonders auffallende Minde­ rung der Häufigkeit dieser Art in Fanggebiet IV dürfte in der Haupt­ sache auf die grossen Neubauflächen zurückzuführen sein. Während von 1959—6 noch 16,1 % auf. ruderarius entfallen, ist er von 1968—69 hier nicht mehr nachweisbar. — Nester oberirdisch und sehr individuen­ arm (Postner 1951). — Schmarotzer wurden noch nicht beobach­ tet. — Variabilität: Die Färbung dieser Art ist im Cuxhavener Ge­ biet ausserordentlich unterschiedlich, wobei die Weibchen und Arbeiterin­ nen auffällig dunkler gefärbt sind als die Männchen. Während erstere meist in der typischen, bis auf den 4.-6. Hinterleibsring, schwarzen Fär­ bung auftreten, konnten von letzteren nur hellere Formen nachgewiesen werden.

description: We use fragmenting jet functions (FJFs) in the context of quarkonia to study the production channels predicted by NRQCD (3 S 1 (1) , 3 S 1 (8) , 1 S 0 (8) , 3 P J (8) ). We choose a set of FJFs that give the probability to find a quarkonium with a given momentum fraction inside a cone-algorithm jet with fixed cone size and energy. This observable gives several lever arms that allow one to distinguish different production channels. In particular, we show that at fixed momentum fraction the individual production mechanisms have distinct behaviors as a function of the the jet energy. As a consequence of this fact, we arrive at the robust prediction that if the depolarizing 1 S 0 (8) matrix element dominates, then the gluon FJF will diminish with increasing energy for fixed momentum fraction, z, and z >0.5

description: PtdIns(4,5)P2 (phosphatidylinositol 4,5-bisphosphate) is a relatively common anionic lipid that regulates cellular functions by multiple mechanisms. Hydrolysis of PtdIns(4,5)P2 by phospholipase C yields inositol trisphosphate and diacylglycerol. Phosphorylation by phosphoinositide 3-kinase yields PtdIns(3,4,5)P3, which is a potent signal for survival and proliferation. Also, PtdIns(4,5)P2 can bind directly to integral and peripheral membrane proteins. As an example of regulation by PtdIns(4,5)P2, we discuss phosphatase and tensin homologue deleted on chromosome 10 (PTEN) in detail. PTEN is an important tumor suppressor and hydrolyzes PtdIns(3,4,5)P3. PtdIns(4,5)P2 enhances PTEN association with the plasma membrane and activates its phosphatase activity. This is a critical regulatory mechanism, but a detailed description of this process from a structural point of view is lacking. The disordered lipid bilayer environment hinders structural determinations of membrane-bound PTEN. A new method to analyze membrane-bound protein measures neutron reflectivity for proteins bound to tethered phospholipid membranes. These methods allow determination of the orientation and shape of membrane-bound proteins. In combination with molecular dynamics simulations, these studies will provide crucial structural information that can serve as a foundation for our understanding of PTEN regulation in normal and pathological processes.

description: Land cover change in the semi-arid environment of the eastern Hindu Kush region is driven by anthropogenic activities and environmental change impacts. Natural hazards, such as floods presumably influenced by climatic change, cause abrupt change of land cover. So far, little research has been conducted to investigate the spatiotemporal aspects of this abrupt change in the valleys. In order to explore the abrupt change in land cover and floods as its possible drivers in the eastern Hindu Kush, a semi-arid mountain region characterized by complex terrain, vegetation variation, and precipitation seasonality, we analyzed long-term Landsat image time series from 1988 to 2020 using Breaks For Additive Seasonal and Trend (BFAST). Overall, BFAST effectively detected abrupt change by using Landsat-derived Modified Soil Adjusted Vegetation Index (MSAVI). The results of our study indicate that approximately 95% of the study area experienced at least one abrupt change during 1988–2020. The years 1991, 1995, 1998, 2007, and 2016 were detected as the peak years, with the peaks occurring in different seasons. The annual trend of abrupt change is decreasing for the study area. The seasonality of abrupt change at the catchment level shows an increasing trend in the spring season for the southern catchments of Panjkora and Swat. The spatial distribution patterns show that abrupt change is primarily concentrated in the floodplains indicating that flooding is the primary driver of the land cover change in the region. We also demonstrated the accurate detection of past flood events (2015) based on the two case examples of Ayun, Rumbur, and Kalash valleys. The detection of the flood events was verified by fieldwork and historical high-resolution Google Earth imagery. Finally, our study provides an example of applying Landsat time series in a dry mountain region to detect abrupt changes in land cover and analyze impact of natural hazards such as floods.

description: Quantum cascade lasers are unipolar semiconductor lasers covering a wide range of the infrared and terahertz spectrum. Lasing action is achieved by using optical intersubband transitions between quantized states in specifically designed multiple-quantum-well heterostructures. A systematic improvement of quantum cascade lasers with respect to operating temperature, efficiency and spectral range requires detailed modeling of the underlying physical processes in these structures. Moreover, the quantum cascade laser constitutes a versatile model device for the development and improvement of simulation techniques in nano- and optoelectronics. This review provides a comprehensive survey and discussion of the modeling techniques used for the simulation of quantum cascade lasers. The main focus is on the modeling of carrier transport in the nanostructured gain medium, while the simulation of the optical cavity is covered at a more basic level. Specifically, the transfer matrix and finite difference methods for solving the one-dimensional Schrödinger equation and Schrödinger-Poisson system are discussed, providing the quantized states in the multiple-quantum-well active region. The modeling of the optical cavity is covered with a focus on basic waveguide resonator structures. Furthermore, various carrier transport simulation methods are discussed, ranging from basic empirical approaches to advanced self-consistent techniques. The methods include empirical rate equation and related Maxwell-Bloch equation approaches, self-consistent rate equation and ensemble Monte Carlo methods, as well as quantum transport approaches, in particular the density matrix and non-equilibrium Green's function (NEGF) formalism. The derived scattering rates and self-energies are generally valid for n-type devices based on one-dimensional quantum confinement, such as quantum well structures.
Oxygen Vacancies on SrO-terminated SrTiO3(001) Surfaces studied by Scanning Tunneling Spectroscopy

description: The electronic structure of SrTiO3(001) surfaces was studied using scanning tunneling spectroscopy and density-functional theory. With high dynamic range measurements, an in-gap transition level was observed on SrO-terminated surfaces, at 2.7 eV above the valence band maximum. The density of centers responsible for this level was found to increase with surface segregation of oxygen vacancies and decrease with exposure to molecular oxygen. Based on these finding, the level is attributed to surface O vacancies. A level at a similar energy is predicted theoretically on SrO-terminated surfaces. For TiO2-terminated surfaces, no discrete in-gap state was observed, although one is predicted theoretically. This lack of signal is believed to be due to the nature of defect wavefunction involved, as well as the possible influence of transport limitations in the tunneling spectroscopy measurements.

description: We study the counterion distribution around a spherical macroion and its  osmotic pressure in the framework of the recently developed  Debye-Hückel-hole-cavity (DHHC) theory. This is a local density  functional approach which incorporates correlations into  Poisson-Boltzmann theory by adding a free energy correction based on the  one-component plasma. We compare the predictions for ion distribution  and osmotic pressure obtained by the full theory and by its zero  temperature limit with Monte Carlo simulations. They agree excellently  for weakly developed correlations and give the correct trend for  stronger ones. In all investigated cases the DHHC theory and its  computationally simpler zero temperature limit yield better results than  the Poisson-Boltzmann theory.

Creators: name: Webb, Nigel
Publisher: name: University of Glasgow

description: A detailed examination of the interactions between individuals and their wider social experiences is the primary aim of this thesis. It is intended that such an investigation will present a picture of local society within which the ties between individuals and families are more multi-faceted than a strict feudal presentation of society would allow. This formulation takes into account a number of components and involves the important consideration of religious patronage as an indicator of local attachments. The investigation of the social role of religious patronage, including consideration of personal motivation and the politics of choice, will be the subject of two chapters and will provide an important indication of the strength of local attachments and social ties. The main theme throughout this work will be that the development of local society involved the integration of a number of social groups within a framework provided by relatively clear geographical boundaries. This thesis thus aims to portray the main characteristics of local society in more three dimensional terms than have been previously attempted, by approaching the subject from a number of different angles. The thesis will accordingly elaborate the existing picture of Scottish society, through the movement of discussion away from the narrow confines of superior lordship.

description: We have measured parity-violating asymmetries in elastic electron-proton and quasielastic electron-deuteron scattering at Q2=0.22 and 0.63  GeV2. They are sensitive to strange quark contributions to currents in the nucleon and the nucleon axial-vector current. The results indicate strange quark contributions of ≲10% of the charge and magnetic nucleon form factors at these four-momentum transfers. We also present the first measurement of anapole moment effects in the axial-vector current at these four-momentum transfers.

description: We explore the stability of structures exhibiting hybridization gaps across a broad range of binary and ternary intermetallic compositions by means of band structure and total energy calculations. This search reveals previously unknown metal-based insulators, some with large gaps exceeding 1 eV, such as Al2Fe and Al4IrRe. We confirm large gaps using a hybrid density functional including exact exchange, and predict a gap of 2.2 eV for AlMnSi in the Pearson type tP6 structure, which is a chemically ordered ternary variant of the prototype MoSi2(Pearson type tI6) structure.

description: GaN films are grown by plasma-assisted molecular beam epitaxy on SiC substrates. The width of the x-ray rocking curve for the (1 0 -1 2) reflection exhibits a distinct minimum for Ga/N flux ratios which are only slightly greater than unity. Correlated with this minimum the surface morphology is somewhat rough, with a hill and valley topography. Based on transmission electron micrographs, the reduction in rocking curve width is attributed to enhanced annihilation of edge dislocations due to their tendency to cluster at topographic valleys.

description: A molecule can be optically accelerated to rotate unidirectionally at a frequency of a few terahertzes which is many orders higher than the classical mechanical rotor. Such a photon-induced ultrafast molecular unidirectional rotation has been well explored as a controllable spin of the molecular nuclear wave packet. Although it has been observed for more than 10 years, a complete imaging of the unidirectional rotating nuclear wave packet is still missing, which is essentially the cornerstone of all the exploring applications. Here, for the first time, we experimentally visualize the time-dependent evolution of the double-pulse excited molecular unidirectional rotation by Coulomb explosion imaging the rotational nuclear wave packet. Our results reveal comprehensive details undiscovered in pioneering measurements, which exhibits as a joint of the quantum revival of the impulsively aligned rotational wave packet and its unidirectional rotation following the angular momentum conservation. The numerical simulations well reproduce the experimental observations and intuitively revivify the thoroughgoing evolution of the rotational wave packet.

Neutrino Tridents in the NOvA Near Detector
Creators: name: Smith, Erica

Publisher: name: Zenodo
Year: 2020

description: NOvA is a long-baseline accelerator-based neutrino oscillation experiment that uses the NuMI beam from Fermilab to measure electron-neutrino appearance and muon-neutrino disappearance using a Near Detector, located at Fermilab, and a Far Detector, located in Ash River, Minnesota. The high flux of muon neutrinos at the Near Detector allows for measurement of rare processes such as neutrino trident scattering, a Standard Model process in which a charged-lepton pair is produced via neutrino-nucleus scattering. The event rate of this process may give insight into a Beyond the Standard Model interaction involving a Z' boson as a mediator. This poster will discuss estimates of the event rates, which are on the order of tens to hundreds, detail a method to reconstruct these events, and evaluate the viability of measuring an event rate in the NOvA Near Detector.

What is “Data Protection Policy”? How it distinct from prior policies on data protection? While the need for comprehensive data protection measures is imperative, countries differ in terms of the scope, aim, and level of enforcement of this policy. Why and how Indonesia adopted a data protection law (UU PDP) as its primary approach to digital governance amidst the seemingly weak public concerns on data protection?

description: Double-spin asymmetries and absolute cross sections were measured at large Bjorken x  (0.25≤x≤0.90), in both the deep-inelastic and resonance regions, by scattering longitudinally polarized electrons at beam energies of 4.7 and 5.9 GeV from a transversely and longitudinally polarized He3 target. In this dedicated experiment, the spin structure function gHe32 was determined with precision at large x, and the neutron twist-3 matrix element dn2 was measured at ⟨Q2⟩ of 3.21 and 4.32  GeV2/c2, with an absolute precision of about 10−5. Our results are found to be in agreement with lattice QCD calculations and resolve the disagreement found with previous data at ⟨Q2⟩=5  GeV2/c2. Combining dn2 and a newly extracted twist-4 matrix element fn2, the average neutron color electric and magnetic forces were extracted and found to be of opposite sign and about 30  MeV/fm in magnitude.

description: The starting substrate 5-chloro-4,9-dimethoxy-7-oxo-7H-furo[3,2-g]chromene-6-carbonitrile (2) was efficiently synthesized from chlorination of the corresponding hydroxy derivative. The presence of adjacent cyano and chloro functions was employed for construction a variety of five, six and seven membered rings annulated furo[3,2-g]chromenes. Treating precursor 2 with hydrazine, phenylhydrazine and hydroxylamine yielded furo[3,2:6,7]chromeno[4,3-c]pyrazoles 3, 4 and furo[3,2:6,7] chromeno[3,4-d]isoxazole 5, respectively. Also, reaction of compound 2 with a diversity of 1,3-N,N-binucleophiles such as guanidine, cyanoguanidine, thiourea, acetamidine and benzamidine produced annulated furo[3,2:6,7]chromeno[4,3-d]pyrimidines 6–10, respectively. Further, treatment of compound 2 with a variety of 1,4-binucleophiles namely ethylenediamine, o-phenylenediamine and 2-aminophenol yielded furo[3,2:6,7]chromeno[4,3-e][1,4]diazepine 11, furo[3,2:6,7]chromeno[4,3-b][1,5]benzodiazepine 12 and furo[3,2:6,7]chromeno[4,3-b][1,5]benzoxazepine 13, respectively. Some of the synthesized compounds seemed good antimicrobial activity especially compounds 3, 6 and 8. Using analytical and spectral results, the structures of the prepared compounds were established.

description: An efficient method of synthesizing the various 3-Fluorochromones from enamino ketones by using N-Fluoro benzenesulfonimide (NFSI) is described. The key step in the synthesis involves tandem cyclization and fluorination to form 3-fluorochromones in good yields. The significant features of this method include simple operational procedures, high purity of the product and cost reducing. This reaction achieved good to excellent yields (51–92%) under ambient conditions with significantly faster rate. The products obtained were confirmed by 1H, 13C NMR and mass spectroscopy techniques.
On the Approximation of the Sum of Lognormals by a Log Skew Normal Distribution

description: Several methods have been proposed to approximate the sum of lognormal RVs. However the accuracy of each method relies highly on the region of the resulting distribution being examined, and the individual lognormal parameters, i.e., mean and variance. There is no such method which can provide the needed accuracy for all cases. This paper propose a universal yet very simple approximation method for the sum of Lognormals based on log skew normal approximation. The main contribution on this work is to propose an analytical method for log skew normal parameters estimation. The proposed method provides highly accurate approximation to the sum of lognormal distributions over the whole range of dB spreads for any correlation coefficient. Simulation results show that our method outperforms all previously proposed methods and provides an accuracy within 0.01 dB for all cases.

Psithyrus vestalis

description: 3. Ps. vestalis (GeoffroY in FourcroY, 1785) Ps. vestalis ist nach Stoeckhert über ganz Deutschland verbreitet und nicht selten. Der Wirt ist B. terrestris. Im Cuxhavener Gebiet konnte Ps. vestalis noch nicht nachgewiesen werden. Alfkens (1913) für diese Art fälschlicherweise angegebenen Fundorte von Ahrensch, Berensch und Ox­ stedt beziehen sich tatsächlich auf die Art Ps. bohemicus (Alfken 1938, S. 25).

Sensitivity to Nucleon Decay in Theia
Creators: name: Askins, Morgan
Publisher: name: Zenodo
Year: 2020

description: New developments in the production of water-based liquid scintillators and the separation of scintillation and Cherenkov light would make it possible for Theia to provide unique sensitivity to many modes of nucleon decay. While modes of decay with low-mass daughters, such as $p \rightarrow e^+ \pi^0$, are best studied with large Cherenkov detectors, decays with heavy products below the Cherenkov threshold ($p \rightarrow \nu K$) only are undetectable in pure Cherenkov detectors except through secondary interactions and nuclear deexcitations. The addition of scintillation light will lead to increased sensitivity and background rejection for $p \rightarrow \nu K$, where the $K$ is always below the Cherenkov threshold. At the lower-end of the spectrum, nucleon decay through invisible modes are only detectable by their subsequent nuclear deexcitations which benefit most from increased energy resolution and background suppression.

description: In this work we consider a DBI Galileon (DBIG) inflationary model and constrain its parameter space with the Planck 2015 and BICEP2/Keck array and Planck (BKP) joint analysis data by means of a potential independent analysis. We focus our attention on inflationary solutions characterized by a constant or varying sound speed as well as warp factor. We impose bounds on stringy aspects of the model, such as the warp factor $\left(f\right)$ and the induced gravity parameter $\left(\tilde{m}\right)$. We study the parameter space of the model and find that the tensor-to-scalar ratio can be as low as $r\simeq6\times10^{-4}$ and inflation happens to be at GUT scale. In addition, we obtain the tilt of the tensor power spectrum and test the standard inflationary consistency relation $\left(r=-8n_{t}\right)$ against the latest bounds from the combined results of BKP+Laser Interferometer Gravitational-Waves Observatory (LIGO), and find that DBIG inflation predicts a red spectral index for the tensor power spectrum.

description: A novel, green, solvent-free, and efficient method has been developed for the one-pot reductive amination of carbonyl compounds using thiamin hydrochloride as a catalyst. This method has performed reductive amination on various functionalized amines and aldehydes, including aliphatic, aromatic, and heteroaromatic ones. The reductive amination of the carbonyl compounds occurred in a single step without any side reaction. The key benefits of this technique included its easiness, greener protocol, quick transformation, variety of substrates, outstanding yield, metal-free, and catalyst recyclability. This helps to make the procedure practical, affordable, and biodegradable.

description: Steps on GaAs(110) surfaces, with step-normal vectors parallel to [001], are studied by scanning tunneling microscopy and spectroscopy. Two possible orientations of the steps occur, with outward normal vectors of [001] or [00-1], which in simple bulk-terminated form have Ga (cations) or As (anions) on their edges, respectively. The latter type of step in n-type or undoped material is found to retain its bulk-terminated form. A band of states is observed extending out from the valence band, associated with the dangling bonds of the terminating As atoms. It is argued that compensation of the dangling bonds on the step edges is the driving force for the step structure, producing reconstruction of the step edges in certain cases.

description: Using x-ray diffraction and NMR spectroscopy, we present structural and  material properties of phosphatidylserine (PS) bilayers that may account  for the well documented implications of PS headgroups in cell activity.  At 30°C, the 18-carbon monounsaturated DOPS in the fluid state has a  cross-sectional area of 65.3Å2 which is remarkably smaller than the area 72.5Å2 of the DOPC analog, despite the extra electrostatic repulsion expected  for charged PS headgroups. Similarly, at 20°C, the 14-carbon disaturated  DMPS in the gel phase has an area of 40.8Å2 vs. 48.1Å2 for DMPC. This condensation of area suggests an extra attractive  interaction, perhaps hydrogen bonding, between PS headgroups. Unlike  zwitterionic lipids, stacks of PS bilayers swell indefinitely as water  is added. Data obtained for osmotic pressure versus interbilayer water  spacing for fluid phase DOPS are well fit by electrostatic interactions  calculated for the Gouy-Chapman regime. It is shown that the  electrostatic interactions completely dominate the fluctuational  pressure. Nevertheless, the x-ray data definitively exhibit the effects  of fluctuations in fluid phase DOPS. From our measurements of  fluctuations, we obtain the product of the bilayer bending modulus KC and the smectic compression modulus B. At the same interbilayer separation, the interbilayer fluctuations are smaller in DOPS than for DOPC, showing that B and/or KC are larger. Complementing the x-ray data, 31P-chemical  shift anisotropy measured by NMR suggest that the DOPS headgroups are  less sensitive to osmotic pressure than DOPC headgroups, which is  consistent with a larger KC in DOPS. Quadrupolar splittings for D2O  decay less rapidly with increasing water content for DOPS than for  DOPC, indicating greater perturbation of interlamellar water and  suggesting a greater interlamellar hydration force in DOPS. Our  comparisons between bilayers of PS and PC lipids with the same chains  and the same temperature enable us to focus on the effects of these  headgroups on bilayer properties.

description: The two-dimensional atomically thin insulator hexagonal boron nitride (h-BN) constitutes a new paradigm in tunnel based devices. A large band gap along with its atomically flat nature without dangling bonds or interface trap states makes it an ideal candidate for tunnel spin transport in spintronic devices. Here, we demonstrate the tunneling of spin-polarized electrons through large area monolayer h-BN prepared by chemical vapor deposition in magnetic tunnel junctions. In ferromagnet/h-BN/ferromagnet heterostructures fabricated over a chip scale, we show tunnel magneto resistance at room temperature. Measurements at different bias voltages and on multiple devices with different ferromagnetic electrodes establish the spin polarized tunneling using h-BN barriers. These results open the way for integration of 2D monolayer insulating barriers in active spintronic devices and circuits operating at ambient temperature, and for further exploration of their properties and prospects.

Ps. bohemicus (Seidl, 1837) (= distinctus Perez, 1884) Flugzeiten: alte ♀♀ 14. 4. — 1. 9., ♂ ♂. 7. — 11. 9. — In Deutsch­ land weit verbreitet und überall häufiger als Ps. vestalis, nach Alfken überall verbreitet und sehr häufig. Es werden die Fundorte Ahrensch, Berensch und Oxstedt genannt, so dass wohl angenommen werden kann, dass diese Art zu jener Zeit bereits auch im Raum Cuxhaven heimisch war. A. C. W. Wagner verzeichnet 1937 109 Fundorte. 1959—6 und 1968—69 wurden insgesamt 3 Weibchen und 7 Männchen in den unbe­ bauten Geest- bzw. Marschgebieten I, VIII und IX nachgewiesen, d. s. 23,8% aller berücksichtigten Psithyrus-Individuen. (1958 wurden bereits 2 Weibchen in Gebiet I gefangen.) — Wirt: B. lucorum. Diese Angabe dürfte auch für Cuxhaven zutreffen, da die hier nachgewiesenen Weib­ chen von Ps. bohemicus bislang ausschliesslich in dem vornehmlich von B. lucorum beflogenen Heide-Fanggebiet I beobachtet wurden

Structure Function Sum rules for Systems with Large Scattering Lengths

description: We use a dispersion relation in conjunction with the operator product expansion (OPE) to derive model independent sum rules for the dynamic structure functions of systems with large scattering lengths. We present an explicit sum rule for the structure functions that control the density and spin response of the many-body ground state. Our methods are general and apply to either fermions or bosons which interact through two-body contact interactions with large scattering lengths. By employing a Borel transform of the OPE, the relevant integrals are weighted toward infrared frequencies, thus allowing for greater overlap low energy data. Similar sum rules can be derived for other response functions. The sum rules can be used to extract the contact parameter introduced by Tan, including universality violating corrections at finite scattering lengths.

description: The starting substrate 5-chloro-4,9-dimethoxy-7-oxo-7H-furo[3,2-g]chromene-6-carbonitrile (2) was efficiently synthesized from chlorination of the corresponding hydroxy derivative. The presence of adjacent cyano and chloro functions was employed for construction a variety of five, six and seven membered rings annulated furo[3,2-g]chromenes. Treating precursor 2 with hydrazine, phenylhydrazine and hydroxylamine yielded furo[3,2:6,7]chromeno[4,3-c]pyrazoles 3, 4 and furo[3,2:6,7] chromeno[3,4-d]isoxazole 5, respectively. Also, reaction of compound 2 with a diversity of 1,3-N,N-binucleophiles such as guanidine, cyanoguanidine, thiourea, acetamidine and benzamidine produced annulated furo[3,2:6,7]chromeno[4,3-d]pyrimidines 6–10, respectively. Further, treatment of compound 2 with a variety of 1,4-binucleophiles namely ethylenediamine, o-phenylenediamine and 2-aminophenol yielded furo[3,2:6,7]chromeno[4,3-e][1,4]diazepine 11, furo[3,2:6,7]chromeno[4,3-b][1,5]benzodiazepine 12 and furo[3,2:6,7]chromeno[4,3-b][1,5]benzoxazepine 13, respectively. Some of the synthesized compounds seemed good antimicrobial activity especially compounds 3, 6 and 8. Using analytical and spectral results, the structures of the prepared compounds were established.

description: Let $E$ be an elliptic curve described by either an Edwards model or a twisted Edwards model over $\mathbb{F}_p$, namely, $E$ is defined by one of the following equations $x^2+y^2=a^2(1+x^2y^2),\, a^5-a\not\equiv 0$ mod $p$, or, $ax^2+y^2=1+dx^2y^2,\,ad(a-d)\not\equiv0$ mod $p$, respectively. We express the number of rational points of $E$ over $\mathbb{F}_p$ using the Gaussian hypergeometric series $\displaystyle {_2F_1}\left(\begin{matrix} ϕ&ϕ {} & ε \end{matrix}\Big| x\right)$ where $ε$ and $ϕ$ are the trivial and quadratic characters over $\mathbb{F}_p$ respectively. This enables us to evaluate $|E(\mathbb{F}_p)|$ for some elliptic curves $E$, and prove the existence of isogenies between $E$ and Legendre elliptic curves over $\mathbb{F}_p$.

description: Quantitative structures are obtained at 30 degrees C for the fully hydrated fluid phases of palmitoyloleoylphosphatidylcholine (POPC), with a double bond on the sn-2 hydrocarbon chain, and for dierucoylphosphatidylcholine (di22:1PC), with a double bond on each hydrocarbon chain. The form factors F(qz) for both lipids are obtained using a combination of three methods. (1) Volumetric measurements provide F(0). (2) X-ray scattering from extruded unilamellar vesicles provides /F(qz)/ for low q(z). (3) Diffuse X-ray scattering from oriented stacks of bilayers provides /F(qz)/ for high q(z). Also, data using method (2) are added to our recent data for dioleoylphosphatidylcholine (DOPC) using methods (1) and (3); the new DOPC data agree very well with the recent data and with (4) our older data obtained using a liquid crystallographic X-ray method. We used hybrid electron density models to obtain structural results from these form factors. The result for area per lipid (A) for DOPC 72.4 +/- 0.5 A(2) agrees well with our earlier publications, and we find A = 69.3 +/- 0.5 A2 for di22:1PC and A = 68.3 +/- 1.5 A2 for POPC. We obtain the values for five different average thicknesses: hydrophobic, steric, head-head, phosphate-phosphate and Luzzati. Comparison of the results for these three lipids and for our recent dimyristoylphosphatidylcholine (DMPC) determination provides quantitative measures of the effect of unsaturation on bilayer structure. Our results suggest that lipids with one monounsaturated chain have quantitative bilayer structures closer to lipids with two monounsaturated chains than to lipids with two completely saturated chains.
