Cuckoo Search Optimization Algorithm Based MPPT Technique for Photovoltaic Systems Under Partial Shading Condition
Creators: name: Shambavi.N, Dr. V.Gopalakrishnan
Publisher: name: Zenodo
Year: 2024

description: The main aim of this research work is to provide maximum power point tracking (MPPT) design for photovoltaic systems using the Cuckoo Search algorithm technique. Due to the fact that the power to voltage characteristics of partially shadowed solar arrays create several peaks, a strong optimization strategy is desperately capture the peak of these arrays rather than just local ones. The required optimization method must detect the global peak with rapid convergence and accuracy. The P-V and I-V curves show multiple Local Maximums (LM) and a Global Maximum (GM) when partial shading (PS) is present. Through the Maximum Power Point Tapping process, the Cuckoo Search algorithm dynamically switches between the exploratory and exploitative phases, resulting in exceptional dynamic reaction and high convergence speed. Several simulations were run in the Matlab/Simulink system for various shading patterns to assess the practicality of the suggested method. The simulation results demonstrate the accuracy of the proposed approach for controlling the energy output at solar panels. Experiments show that the proposed method can reliably track global peaks and handle partial shading with optimal efficacy.

description: We experimentally measure the density of states (DOS) and dynamical structure factor (DSF) arising from the thermal fluctuations in a colloidal crystal composed of thermally sensitive micron-sized hydrogel particles at several different particle volume fractions, ϕ’s. Particle positions are tracked over long times using optical microscopy and particle tracking algorithms in a single two-dimensional (2D) [111]plane of a 3D face-centered-cubic single crystal. The dynamical fluctuations are spatially heterogeneous while the lattice itself is highly ordered. At all ϕ’s, the DOS exhibits an excess of low frequency modes, a so-called boson peak (BP), and the DSF exhibits a cross-over from propagating to nonpropagating behavior, a so-called Ioffe-Regel crossover, at a frequency somewhat below the BP for both longitudinal and transverse modes. As we tune ϕ from 0.64 to 0.56, the Lindemann parameter grows from ~3% to ~8%; however, the shape of the DOS and DSF remain largely unchanged when rescaled by the Debye level. This invariance indicates that the effective degree of disorder remains essentially constant even in the vicinity of melting.
The Three-dimensional Evolution of Rising, Twisted Magnetic Flux Tubes in a Gravitationally Stratified Model Convection Zone

description: We present three-dimensional numerical simulations of the rise and fragmentation of twisted, initially horizontal magnetic flux tubes which evolve into emerging Omega-loops. The flux tubes rise buoyantly through an adiabatically stratified plasma that represents the solar convection zone. The MHD equations are solved in the anelastic approximation, and the results are compared with studies of flux tube fragmentation in two dimensions. We find that if the initial amount of field line twist is below a critical value, the degree of fragmentation at the apex of a rising Omega-loop depends on its three-dimensional geometry: the greater the apex curvature of a given Omega-loop, the lesser the degree of fragmentation of the loop as it approaches the photosphere. Thus, the amount of initial twist necessary for the loop to retain its cohesion can be reduced substantially from the two-dimensional limit. The simulations also suggest that as a fragmented flux tube emerges through a relatively quiet portion of the solar disk, extended crescent-shaped magnetic features of opposite polarity should form and steadily recede from one another. These features eventually coalesce after the fragmented portion of the Omega-loop emerges through the photosphere.

This paper settles the remaining cases, which are of a different nature because Lie($G$) has a more complicated structure and there need not exist general dimension bounds of the sort that exist in good characteristic.

description: The effect of Nb substitution on the nanocrystallization process and high temperature magnetic properties of FeCoSiBCu nanocomposites is reported. Magnetization changes accompany the primary crystallization of α-Fe(Co) nanocrystals and the secondary crystallization of (FeCo)23B6and (FeCo)2B phases. With increasing the Nb fraction in the alloys, the diffusion barrier to growth of α-Fe(Co) nanocrystals increases, resulting in an increase of thermal stability and a delay of Fe(Co) dissolution required for (FeCo)23B6 phase formation. The transmission electron microscopy images reveal finer grains with increasing Nb content.

description: The NN results are presented from the extended-soft-core (ESC) interactions. They cosist of local- and non-local-potentials due to (i) one-boson-exchange (OBE), pseudo-scalar-, vector-, scalar-, and axial-vector-nonets, (ii) diffractive exchanges, (iii) two-pseudoscalar-exchange, and (iv) meson-pair-exchange (MPE). Fits to the pp- and np-data for 0 < T(lab) < 350 MeV have typical χ^2/Ndata= 1.15. Used are less than 20 parameters, which are coupling constants and cut-off masses. The couplings follow rather closely the pattern predicted by the quark-pair-creation model. As a result the 11 OBE-couplings are rather constrained, i.e. quasi-free. The deuteron binding energy and several NN scattering lengths are fitted at the same time.

description: Background Organisms are able to anticipate changes in the daily environment with an internal oscillator know as the circadian clock. Transcription is an important mechanism in maintaining these oscillations. Here we explore, using whole genome tiling arrays, the extent of rhythmic expression patterns genome-wide, with an unbiased analysis of coding and noncoding regions of the Arabidopsis genome. Results As in previous studies, we detected a circadian rhythm for approximately 25% of the protein coding genes in the genome. With an unbiased interrogation of the genome, extensive rhythmic introns were detected predominantly in phase with adjacent rhythmic exons, creating a transcript that, if translated, would be expected to produce a truncated protein. In some cases, such as the MYB transcription factor AT2G20400, an intron was found to exhibit a circadian rhythm while the remainder of the transcript was otherwise arrhythmic. In addition to several known noncoding transcripts, including microRNA, trans-acting short interfering RNA, and small nucleolar RNA, greater than one thousand intergenic regions were detected as circadian clock regulated, many of which have no predicted function, either coding or noncoding. Nearly 7% of the protein coding genes produced rhythmic antisense transcripts, often for genes whose sense strand was not similarly rhythmic. Conclusions This study revealed widespread circadian clock regulation of the Arabidopsis genome extending well beyond the protein coding transcripts measured to date. This suggests a greater level of structural and temporal dynamics than previously known.

On the oxygen abundance determination in HII regions: the problem of the line intensities -- oxygen abundance calibration

Publisher: name: arXiv
Year: 2000

description: The problem of the line intensities -- oxygen abundance calibration has been considered. We confirm the idea of McGaugh (1991) that the strong oxygen lines ([OII] 3727, 3729 and [OIII] 4959, 5007) contain the necessary information for determination of accurate abundances in low-metallicity (and may be also in high-metallicity) HII regions. It has been found that the excitation parameters p3 or p2 (which are defined here as contributions of the radiation in [OIII] 4959, 5007 lines and in [OII] 3727, 3729 lines to the "total" oxygen radiation respectively) allow to take into account the variations in R23 values among HII regions with a given oxygen abundance. Based on this fact a new way of the oxygen abundance determination in HII regions has been constructed and corresponding relations between line intensities and the oxygen abundance have been derived empirically using the available oxygen abundances determined via measurement of temperature-sensitive line ratios. In parallel a new R23 calibration has been derived on the base of recent data and compared to previous calibrations. For oxygen-rich HII regions the present R23 calibration is close to that of Edmunds and Pagel (1984): their calibration has the same slope but is shifted towards higher oxygen abundances by around 0.07 dex as compared to the present calibration.

description: Chamaecyparis lawsoniana ist eine charakteristische Baumart im städtischen und stadtnahen Grün in den USA. Für den Forst ist C. lawsoniana vor allem im nordwestlichen Kalifornien und im südwestlichen Oregon von großer ökonomischer und ökologischer Bedeutung. Mit der Verschiffung von Saatgut 1854 von den USA nach England begann die Selektion und Züchtung von Zierformen in Baumschulen vor allem an der Westküste der USA. 1923 wurde in der Nähe von Seattle (USA) ein vermehrtes Absterben von C. lawsoniana in Baumschulen und in der freien Landschaft beobachtet. Als Ursache konnte 1943 Phytophthora lateralis identifiziert werden. 1952 trat in den USA der Erreger das erste Mal im Wald an C. lawsoniana auf. Inzwischen ist der Erreger im Westen von Nordamerika weit verbreitet, wurde aber bisher nicht in anderen Landesteilen nachgewiesen.
In Europa wurde P. lateralis das erste Mal 1999 in Frankreich an C. lawsoniana in einer Baumschule nachgewiesen. Eine weitere Verbreitung wurde in den folgenden Jahren nicht bekannt. Erst 2005 konnte der Erreger erneut in einer Baumschule in den Niederlanden aus kranken C. lawsoniana isoliert werden. Seit 2005 wurde P. lateralis auch mehrfach in Frankreich in kranken C. lawsoniana-Hecken außerhalb von Baumschulen nachgewiesen.

description: We report the oxidation products and qualitative rates for polydisperse FeCo magnetic nanoparticles (MNPs) synthesized using an induction plasma torch. X-ray diffraction(XRD) and TEM showed MNPs to have a thin ferrite shell. Nanopowders were isochronally annealed to promote oxidation and XRD was used to follow the evolution of the FeCo core and the Fe3O4and FeO oxide shells. Isothermal anneals were used to follow oxidation kinetics at 350 and 500°C. High resolution transmission electron microscopy(HRTEM) revealed faceted morphologies terminated at (100) and (110) FeCo faces with (110)FeCo∥(111)oxide and (100)FeCo∥(100)oxide, and [010]FeCo∥[011]oxide orientation relationships between the FeCo core and oxide shell. We show HRTEM images of MNP chaining and compare the rf heating of samples of aqueous ferrofluids similarly loaded with as synthesized and oxidized MNPs.

description: We report an experimental and numerical study of femtosecond multi-pulse laser-induced densification in vitreous silica (v-SiO2) and its signature in Raman spectra. We compare the experimental findings to recently developed molecular dynamics (MD) approach accounting for bond-breaking due to laser irradiation, together with a dynamical matrix approach and bond polarizability model based on first-principle calculations for the estimation of Raman spectra. We observe two stages of the laser-induced densification and Raman spectrum evolution: growth during several hundreds of pulses followed by further saturation. At the medium-range, the network connectivity change in v-SiO2 is expressed in reduction of major ring fractions leading to more compacted structure. With the help of Sen & Thorpe model, we also study the short-range order transformation and derive the interbonding Si-O-Si angle change from the Raman measurements. Experimental findings are in excellent agreement with our MD simulations, and, hence, support bond-breaking mechanism of laser-induced densification. Thus, our modeling explains well the laser-induced changes both in the short-range order caused by the appearance of Si-coordination defects and medium-range order connected to evolution of the ring distribution. Finally, our findings disclose similarities between sheared-, permanently-densified- and laser-induced-glass and suggest interesting future experiment in order to clarify the impact of the thermo-mechanical history on glasses under shear, cold- and hot-compression, and laser-induced densification.

description: The tricritical behavior of the two-dimensional $q$-state Potts model with vacancies for $1\leq q \leq4$ is argued to be encoded in the fractal structure of the geometrical spin clusters of the pure model. The close connection between the critical properties of the pure model and the tricritical properties of the diluted model is shown to be reflected in an intimate relation between Fortuin-Kasteleyn and geometrical clusters: The same transformation mapping the two critical regimes onto each other also maps the two cluster types onto each other. The map conserves the central charge, so that both cluster types are in the same universality class. The geometrical picture is supported by a Monte Carlo simulation of the high-temperature representation of the Ising model ($q=2$). In this new numerical approach, closed graph configurations are generated by means of a Metropolis update algorithm, involving single plaquettes.

description: International organizations (IOs) are often confronted with contradictory external demands. How do they mediate between the conflicting expectations of their various stakeholders? Drawing on the concept of organizational hypocrisy, this article sheds light on the mediation efforts of IOs. Mediation is understood as the counter-coupling of organizational talk and action that enables IOs to deal with the diverging imperatives of being both a ‘political organization’ and an ‘action organization’. Among other things, this understanding of mediation offers an innovative perspective on the question of why internal criticism by employees often finds little support in IOs. Due to the (necessary) discrepancy between words and action, IOs’ criticism culture is undermined in two ways: (1) internal criticism is suppressed by IO leadership out of fear that the existing hypocrisy could be publicly exposed; and (2) it is a challenge for IO staff to constructively criticize their hypocritical organization without being naive or cynical.

Consider the union of all images of translates of a fixed finite-rank subgroup of $A_0$, also defined over the algebraic numbers, by abelian subvarieties of $A_0$ of codimension at least $k$ under all isogenies between $A_0$ and some fiber of the abelian scheme. We characterize the curves inside the abelian scheme which are defined over the algebraic numbers, dominate the base curve and potentially intersect this set in infinitely many points. Our proof follows the Pila-Zannier strategy.

description: An experimental approach for obtaining perpendicular FePt-SiOx thin films with a large height to diameter ratio FePt(L10) columnar grains is presented in this work. The microstructure for FePt-SiOx composite thin films as a function of oxide volume fraction, substrate temperature, and film thickness is studied by plan view and cross section TEM. The relations between processing, microstructure, epitaxial texture, and magnetic properties are discussed. By tuning the thickness of the magnetic layer and the volume fraction of oxide in the film at a sputtering temperature of 410 °C, a 16 nm thick perpendicular FePt film with ∼8 nm diameter of FePt grains was obtained. The height to diameter ratio of the FePt grains was as large as 2. Ordering at lower temperature can be achieved by introducing a Ag sacrificial layer.

description: In many cases, the stability of complex structures in colloidal systems is enhanced by a competition between different length scales. Inspired by recent experiments on nanoparticles coated with polymers, we use Monte Carlo simulations to explore the types of crystal structures that can form in a simple hard-core square shoulder model which explicitly incorporates two favored distances between the particles. To this end, we combine Monte Carlo-based crystal structure finding algorithms with free energies obtained using a mean-field cell theory approach, and draw phase diagrams for two different values of the square shoulder width as a function of the density and temperature. Moreover, we map out the zero-temperature phase diagram for a broad range of shoulder widths. Our results show the stability of a rich variety of crystal phases, such as body-centered orthogonal (BCO) lattices, not previously considered for the square shoulder model.

description: Magnetic nanoparticles (MNPs) possessing low Curie temperatures (TC’s) offer the possibility for self-regulated heating of cancer cells, where the TC acts as an upper limit to heating to prevent damage to neighboring healthy tissue. We report the synthesis of monodisperse metastable fcc γ-phase Fe–Ni MNPs possessing tunable TC’s, whose stoichiometries have been predicted from metastable extensions to an equilibrium Fe–Ni phase diagram. Metastable alloys have been predicted within the constructs of the T0 construction in the Fe–Ni eutectoid phase diagram. Fe–Ni MNPs have been synthesized via chemical reduction in Fe- and Ni-precursors with stoichiometries ranging from Fe90Ni10 to Fe70Ni30. Mn-precursors have been added to further reduce the alloy’s TC. MNP morphology and structure have been confirmed by x-ray diffraction and transmission electron microscopy while magnetic properties were investigated using vibrating sample magnetometry. Fe70Ni30 MNPs were found to have a TCof 82 °C and specific magnetization of 66 emu/g. Addition of 1 wt % Mn to Fe75Ni25 reduced the TC to 78 °C, which is the lowest reported for fcc Fe–Ni alloys. We also report a model for radio frequency self-regulated heating, in which the maximum achievable temperature of water-MNP suspensions(TC<100 °C) or octyl ether-MNP suspensions(TC>100 °C) is approximately the TC of the MNPs suspended in the solution.
Crosstalk between Notch signaling pathway and Epithelial-mesenchymal transition (EMT), Angiogenesis and Cancer stem cells in Triple Negative Breast Cancer (TNBC)

description: Notch signaling is an evolutionary conserved cell signaling pathway, when dysregulated can cause high cellular proliferation, high mobility capabilities, drug resistance which contribute to the development of TNBC. In this retrospective study, the role of Notch signaling pathway in TNBC progression was explored by analyzing the correlation of Notch reecptors with epithelial-mesenchymal transition (EMT), angiogenesis, and cancer stem cell (CSC) characteristics. Immunohistochemical analysis of Notch receptors (Notch1-4), EMT markers (E-cadherin and vimentin), angiogenesis marker (CD31), and CSC marker (Oct3/4) was conducted on tissue samples from 100 TNBC patients.Significant associations were found between Notch1, membrane Notch3, and nuclear Notch4 with vimentin expression, indicating their role in EMT induction. Moreover, Notch1 and nuclear Notch3 were positively correlated with CD31 expression, suggesting their involvement in angiogenesis regulation. Additionally, Notch1 and membrane Notch3 were associated with Oct3/4 expression, implicating their role in induction of cancer stem cell properties. These findings implicate the importance of Notch signaling in TNBC aggressiveness and suggest Notch receptors as potential therapeutic targets.

description: Growing evidence supports the suggestion that the compact high-velocity clouds of HI (CHVCs) are located throughout the Local Group and continue to fuel galactic evolution. Recent distance estimates to individual objects lie in the range 150-850 kpc, implying an HI mass range of 10^5.7 to 10^7.2 M_Sun together with sizes ranging from 2-12 kpc, while the average linewidth is 30 km/s FWHM. It is natural to ask whether objects of this type would not already have been seen by current blind HI surveys of the extragalactic sky. We consider the properties of the deepest published surveys of this type and conclude that the sensitivity and coverage have now begun to reveal the high mass end of the distribution (M_HI >10^7 M_Sun). Achieving detection limits an order of magnitude deeper should finally enable direct study of these systems beyond the Local Group, or definitively rule out their existence.

description: A technique based on x-ray diffraction (XRD) is introduced to understand the variation of the grain-to-grain L10 ordering in FePt recording media. We classify the possible ways that the grains may be ordered into three types: homogeneous ordering, inhomogeneous ordering, and bipolar ordering. We study the possible impact of each type of ordering on the XRD spectra in terms of the relative angular positions of the FePt (001) and (002) peaks. XRD peak profile fitting is carried out to identify the grain ordering type in FePt-SiOx thin films sputtered with in-situ heating.

description: We show that entanglement between two solitary qubits in quasi-one-dimensional Bose-Einstein condensates can be spontaneously generated due to quantum fluctuations. Recently we have shown that dark solitons are an appealing platform for qubits thanks to their appreciable long lifetime. We investigate the spontaneous generation of entanglement between dark-soliton qubits in the dissipative process of spontaneous emission. By driving the qubits with the help of oscillating magnetic field gradients, we observe the formation of long distance steady-state concurrence. Our results suggest that dark-soliton qubits are good candidates for quantum information protocols based purely on matter-wave phononics.

description: We present a three dimensional (3D) extinction analysis in the region toward the supernova remnant (SNR) S147 (G180.0-1.7) using multi-band photometric data from the Xuyi Schmidt Telescope Photometric Survey of the Galactic Anticentre (XSTPS-GAC), 2MASS and WISE. We isolate a previously unrecognised dust structure likely to be associated with SNR S147. The structure, which we term as "S147 dust cloud", is estimated to have a distance $d$ = 1.22 $\pm$ 0.21 kpc, consistent with the conjecture that S147 is associated with pulsar PSR J0538 + 2817. The cloud includes several dense clumps of relatively high extinction that locate on the radio shell of S147 and coincide spatially with the CO and gamma-ray emission features. We conclude that the usage of CO measurements to trace the SNR associated MCs is unavoidably limited by the detection threshold, dust depletion, and the difficulty of distance estimates in the outer Galaxy. 3D dust extinction mapping may provide a better way to identify and study SNR-MC interactions.

Case and agreement in Brazilian Portuguese: Between Bantu and Romance
Creators: name: Galves, Charlotte
name: Avelar, Juanito
Publisher: name: Zenodo
Year: 2021

description: This chapter presents some syntactic peculiarities of Brazilian Portuguese which
 differentiate it from European Portuguese and, from a typological point of view, put
 it apart in the Romance and even in the Indo-European domain. We argue that this
 is due to the influence of the African languages (mostly from the Bantu subgroup)
 that were taken to Brazil by the slave trade during three centuries. We propose
 that this change affected T(ense), more exactly T’s EPP condition, which ceased to
 be φ-dependent, with the consequence that SpecTP became an A-bar position. On
 the basis of the criteria proposed by Sheehan & van der Wal (2018), we discuss the
 status of syntactic Case in Brazilian Portuguese and depart from a previous analysis
 that argued that, in this language, DPs could enter the derivation without a case
 feature. In the analysis proposed in this chapter, Case and EPP nicely combine to
 account for the facts considered.
Extended-soft-core Baryon-Baryon Model II. Hyperon-Nucleon Interaction
Creators: name: Rijken, Th. A.
name: Yamamoto, Y.
Publisher: name: arXiv
Year: 2006
Subjects: subject: Nuclear Theory (nucl-th)
subject: FOS: Physical sciences

description: The YN results are presented from the Extended-soft-core (ESC) interactions. They consist of local- and non-local-potentials due to (i) One-boson-exchange (OBE), with pseudoscalar-, vector-, scalar-, and axial-vector-nonets, (ii) Diffractive exchanges, (iii) Two-pseudoscalar exchange, and (iv) Meson-pair-exchange (MPE). This model, called ESC04, describes NN and YN in a unified way using broken flavor SU(3)-symmetry. Novel ingredients are the inclusion of (i) the axial-vector-mesons, (ii) a zero in the scalar- and axial-vector meson form factors. We describe simultaneous fits to the NN- and YN-data, using four options in the ESC-model. Very good fits were obtained. G-matrix calculations with these four options are also reported. The obtained well depths (U_Λ, U_Σ, U_Ξ) reveal distinct features of ESC04a-d. The ΛΛ-interactions are demonstrated to be consistent with the observed data of_{ΛΛ}^6He. The possible three-body effects are investigated by considering phenomenologically the changes of the vector-meson masses in a nuclear medium.

Extended Falicov-Kimball model: exact solution for the ground state

description: The extended Falicov-Kimball model is analyzed exactly in the ground state at half filling in the limit of large dimensions. In the model the on-site and the intersite density-density interactions between all particles are included. We determined the model's phase diagram and found a discontinuous transition between two different charge-ordered phases. Our analytical calculations show that the ground state of the system is insulating for any nonzero values of the interaction couplings. We also show that the dynamical mean-field theory and the static broken-symmetry Hartree-Fock mean-field approximation give the same results for the model at zero temperature. In addition, we prove using analytical expressions that at infinitesimally small, but finite, temperatures the system can be metallic.

description: L'ensemble de ces notes ont été crée par John Baldwin lors d'une de ses premières périodes de résidence à Paris. Ces documents comprennent tous les magistri qu’il avait pu rencontrer dans ses sources. Aux XIIème et XIIIème siècles, les universités n'existant pas encore, le titre de magister s'il évoque certainement une compétence n'est pas rattaché de façon systématique au passage par les écoles. De surcroît, les magistris sont le plus souvent désignés par leur seul prénom. La lecture de ces données est donc difficile et suppose un long travail pour tenter d'identifier un individu auquel on pourrait rattacher plusieurs mentions. John Baldwin avait donc renoncé à utiliser ces données pour donner un prolongement à sa magnifique étude sur les gradués d'université et leur emploi par les Capétiens et les Plantagenêts. Néanmoins, il a conservé ces données et elles sont potentiellement très utile dans le cadre de Studium, comme le sont toutes les mentions dans les volumes des Fasti Ecclesiae Gallicanae de chanoines portant ce titre de magister sans autres précisions. L'ampleur des dépouillements rend ces données très utiles et nous devons une grande reconnaissance à John Baldwin pour avoir pris la peine de faire photocopier ses fiches et de nous les avoir transmises amicalement.
Les données ainsi que les images des fiches sont accessibles sur le site Internet à l'adresse suivante : http://studium-baldwin.lamop.fr/.
Les transcriptions des fiches ont été effectuées par des étudiants de Paris 1 Panthéon - Sorbonne mais elles n'ont pas été corrigées par la suite.

Anomaly-Induced Effective Action and Inflation

description: In the early Universe matter can be described as a conformal invariant ultra-relativistic perfect fluid, which does not contribute, on classical level, to the evolution of the isotropic and homogeneous metric. If we suppose that there is some desert in the particle spectrum just below the Planck mass, then the effect of conformal trace anomaly is dominating at the corresponding energies. With some additional constraints on the particle content of the underlying gauge model (which favor extended or supersymmetric versions of the Standard Model rather than the minimal one), one arrives at the stable inflation. We review the model and report about the calculation of the gravitational waves on the background of the anomaly-induced inflation. The result for the perturbation spectrum is close to the one for the conventional inflaton model, and is in agreement with the existing Cobe data (see also [hep-th/0009197]).
