description: There are many subtle issues associated with solving the Navier-Stokes equations. In this paper, several of these issues, which have been observed previously in research involving the Navier-Stokes equations, are studied within the framework of the one-dimensional Kuramoto-Sivashinsky (KS) equation, a model nonlinear partial-differential equation. This alternative approach is expected to more easily expose major points and hopefully identify open questions that are related to the Navier-Stokes equations. In particular, four interesting issues are discussed. The first is related to the difficulty in defining regions of linear stability and instability for a time-dependent governing parameter; this is equivalent to a time-dependent base flow for the Navier-Stokes equations. The next two issues are consequences of nonlinear interactions. These include the evolution of the solution by exciting its harmonics or sub-harmonics (Fourier components) simultaneously in the presence of a constant or a time-dependent governing parameter; and the sensitivity of the long-time solution to initial conditions. The final issue is concerned with the lack of convergent numerical chaotic solutions, an issue that has not been previously studied for the Navier-Stokes equations. The last two issues, consequences of nonlinear interactions, are not commonly known. Conclusions and questions uncovered by the numerical results are discussed. The reasons behind each issue are provided with the expectation that they will stimulate interest in further study.

description: The quantum dynamics of colliding Bose-Einstein condensates with 150 000 atoms are simulated directly from the Hamiltonian using the stochastic positive-P method. Two-body correlations between the scattered atoms and their velocity distribution are found for experimentally accessible parameters. Hanbury Brown-Twiss or thermal-like correlations are seen for copropagating atoms, while number correlations for counterpropagating atoms are even stronger than thermal correlations at short times. The coherent phase grains grow in size as the collision progresses with the onset of growth coinciding with the beginning of stimulated scattering. The method is versatile and usable for a range of cold atom systems.

description: The acetylcholinesterase inhibitory activity of 89 organic extracts from marine organisms was evaluated through a TLC bioautography methodology. Extracts from soft corals (Eunicea and Plexaura) were the most active compared with extracts from sponges. The bioguided chemical study of the most active extract, obtained from Pseudoplexaura porosa, led to the isolation of a diterpene with spectroscopic properties consistent to those published to the cembrane Steylolide. However, further analysis by X-ray diffraction indicated that the compound was the 14-acetoxycrassine (1), correcting the structure reported to the Styelolide. Additionally, the acetylcholinesterase inhibitory activity of fourteen cembranoids (2–15) isolated from soft corals Eunicea knighti and Pseudoplexaura flagellosa was evaluated. Cembranoids 2, 3 and 4 were the most active compounds in the TLC bioassay. Then, the most promising cembranoids, 14-acetoxycrassine (1) and asperdiol (2), were tested quantitatively and they exhibited IC50 values of 1.40 ± 0.113 and 0.358 ± 0.130 μM, respectively.

description: Our contemporary world is characterized by a tremendous momentum of information and communications technology (ICT) applications that have penetrated various areas of life and have greatly modernized both the ways we lead our life today, compared to what life was less than a century ago. Education, in turn, has significantly been influenced by the emerging ICT trends. Therefore, due to the societal status of education, the current research aims to study ICT applications in pre-university education institutions, by studying investigating South Korea case and how it managed to adopt these applications in pre-university education institutions. Heading this purpose, the research tries to find out how Egypt could benefit from the Korean case to develop its corresponding education system through the adoption of ICT within its institutions in accordance with the nature of the Egyptian educational system. The current research uses the comparative approach, the case study style, using primary and official documents, as a study tool. The research proceeds in a set of steps, the first of which is: planning the research framework and its structure e.g., state of the problem, its objectives, its significance, its limitations, and the review of literature. The second step presents a theoretical study of ICT applications in pre-university education, before the research moves through the third and fourth chapters, in its third step, to study the Korean case and the cultural factors that affected its educational system during adopting ICT applications in Korean pre-university education institutions. This is followed by Egypt's efforts to adopt ICT applications in its pre-university educational system institutions, in the fourth step. The fifth step comes to conclude the most important results of the research, divided into three domains: theoretical results, results specific to Korea, and finally results specific to Egypt. Based on these results, the research begins to propose a set of mechanisms for developing ICT applications in pre-university education institutions in Egypt, accompanied with the requirements for this development, and any obstacles that this endeavor may face.

On the Hardness-Intensity Correlation in Gamma-Ray Burst Pulses

description: We study the hardness-intensity correlation (HIC) in gamma-ray bursts (GRBs). In particular, we analyze the decay phase of pulse structures in their light curves. The study comprises a sample of 82 long pulses selected from 66 long bursts observed by BATSE on the Compton Gamma-Ray Observatory. We find that at least 57% of these pulses have HICs that can be well described by a power law. The distribution of the power law indices, obtained by modeling the HIC of pulses from different bursts, is broad with a mean of 1.9 and a standard deviation of 0.7. We also compare indices among pulses from the same bursts and find that their distribution is significantly narrower. The probability of a random coincidence is shown to be very small. In most cases, the indices are equal to within the uncertainties. This is particularly relevant when comparing the external versus the internal shock models. In our analysis, we also use a new method for studying the HIC, in which the intensity is represented by the peak value of the E F_E spectrum. This new method gives stronger correlations and is useful in the study of various aspects of the HIC. In particular, it produces a better agreement between indices of different pulses within the same burst. Also, we find that some pulses exhibit a "track jump" in their HICs, in which the correlation jumps between two power laws with the same index. We discuss the possibility that the "track jump" is caused by strongly overlapping pulses. Based on our findings, the constancy of the index is proposed to be used as a tool for pulse identification in overlapping pulses.

description: Workflow for the proteomic analysis of the adhesive proteomes of Amphibalanus amphitrite and Pollicipes pollicipes. A) First, transcriptomics-based protein sequences of proteins that had previously been identified in the adhesive of A. amphitrite were compared via BlastP to the predicted proteome of the SNU_Aamp genome assembly (GCA_009805615.1). The identified protein sequences (Aamp) were then compared via BlastP to the predicted proteome of the Ppol_2 genome assembly (GCF_011947565.2). B) Next, mass spectrometry files produced from the proteomic analysis of A. amphitrite and P. pollicipes adhesive in prior publications were reanalyzed with the predicted proteomes based on the available genomes. The A. amphitrite samples had previously been analyzed using a Sciex Triple TOF 5600, and were reanalyzed using a Thermo Lumos Orbitrap Fusion mass spectrometer. Sciex files were analyzed with Mascot and Scaffold and Orbitrap files were analyzed with MaxQuant. A. amphitrite Orbitrap files were analyzed with either the SNU_Aamp database or a truncated database containing the NRL transcriptomics-based protein sequences previously identified in the adhesive (Adh DB), and with both databases simultaneously. This was done because no matches in the SNU_Aamp database existed for certain NRL sequences. Locations of the results for each data analysis step are listed in the figure.
Decay chain information on the newly discovered double charm baryon state $Ξ_{cc}^{++}$

description: We interprete the new double charm baryon state found by the LHCb Collaboration in the invariant mass distribution of the set of final state particles $(Λ_c^+\,K^-\,π^+\,π^+)$ as being at the origin of the decay chain $Ξ_{cc}^{++} \to Σ_c^{++} (\to Λ_c^+ π^+) +\bar K^{*0} (\to K^- π^+)$. The nonleptonic decay $Ξ_{cc}^{++} \to Σ_c^{++} + \bar K^{*0}$ belongs to a class of decays where the quark flavor composition is such that the decay proceeds solely via the factorizing contribution precluding a contamination from internal $W$-exchange. We use the covariant confined quark model previously developed by us to calculate the four helicity amplitudes that describe the dynamics of the transition $Ξ_{cc}^{++} \to Σ_c^{++}$ induced by the effective $(c \to u)$ current. We then proceed to calculate the rate of the decay as well as the polarization of the $Σ_c^{++}$ and $Λ_c^+$ baryons and the longitudinal/transverse composition of the $\bar K^{*0}$. We estimate the decay $Ξ_{cc}^{++} \to Σ_c^{++} \bar K^{*0}$ to have a branching rate of $B(Ξ_{cc}^{++} \to Σ_c^{++} \bar K^{*0}) \sim 10.5 \%$. As a byproduct of our investigation we have also analyzed the decay $Ξ_{cc}^{++} \to Σ_c^{++} \bar K^{0}$ for which we find a branching ratio of $B(Ξ_{cc}^{++} \to Σ_c^{++} \bar K^0) \sim 2.5 \%$.

description: The French Revolution brought principles of "liberty, equality, and brotherhood" to bear on the day-to-day challenges of governing what was then the largest country in Europe. Its experiments provided a model for future revolutions and democracies across the globe, but this first modern revolution had no model to follow. Using reconstructed transcripts of debates held in the Revolution's first parliament, we present a quantitative analysis of how this system managed innovation. We use information theory to track the creation, transmission, and destruction of patterns of word-use across over 40,000 speeches and more than one thousand speakers. The parliament as a whole was biased toward the adoption of new patterns, but speakers' individual qualities could break these overall trends. Speakers on the left innovated at higher rates while speakers on the right acted, often successfully, to preserve prior patterns. Key players such as Robespierre (on the left) and Abbé Maury (on the right) played information-processing roles emblematic of their politics. Newly-created organizational functions---such as the Assembly's President and committee chairs---had significant effects on debate outcomes, and a distinct transition appears mid-way through the parliament when committees, external to the debate process, gain new powers to "propose and dispose" to the body as a whole. Taken together, these quantitative results align with existing qualitative interpretations but also reveal crucial information-processing dynamics that have hitherto been overlooked. Great orators had the public's attention, but deputies (mostly on the political left) who mastered the committee system gained new powers to shape revolutionary legislation.

description: Filtering algorithms for two degenerate quark flavours have advanced to the point that, in 2+1 flavour simulations, the cost of the strange quark is significant compared with the light quarks. This makes efficient filtering algorithms for single flavour actions highly desirable, in particular when considering 1+1+1 flavour simulations for QED+QCD. Here we discuss methods for filtering the RHMC algorithm that are implemented within BQCD, an open-source Fortran program for Hybrid Monte Carlo simulations.

The Worldsheet Conformal Field Theory of the Fractional Superstring

Publisher: name: arXiv
Year: 1993
Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: Two of the important unresolved issues concerning fractional superstrings have been the appearance of new massive sectors whose spacetime statistics properties are unclear, and the appearance of new types of ``internal projections'' which alter or deform the worldsheet conformal field theory in a highly non-trivial manner. In this paper we provide a systematic analysis of these two connected issues, and explicitly map out the effective post-projection worldsheet theories for each of the fractional-superstring sectors. In this way we determine their central charges, highest weights, fusion rules, and characters, and find that these theories are isomorphic to those of free worldsheet bosons and fermions. We also analyze the recently-discovered parafermionic ``twist current'' which has been shown to play an important role in reorganizing the fractional-superstring Fock space, and find that this current can be expressed directly in terms of the primary fields of the post-projection theory. This thereby enables us to deduce some of the spacetime statistics properties of the surviving states.

Subjects: social Aciences

description: The purpose of this study is to investigate the impact of bureaucracy problems on investment opportunities. A well-structured five Likert's scale questionnaire is used to collect data from a targeted population of 280 respondents. Data collected is used to give clear answers to wither bureaucracy problems have impact on investment opportunities or not.  Statistical package No 16 is used to generate analysis.  Various kinds of statistics were included such as tables, means and standard deviations, coefficients and so on. Results have confirmed that these problems have strong negative impact on investment opportunities in Jordan, therefore the null hypothesis are rejected. Given the significant strong negative relationship between bureaucracy problems and investment opportunities, it is practically necessary to continuously improve public operational systems and avoid the adoption of excessive bureaucratic systems. Flexible systems and Easier and simpler procedures can be reinforced to weaken the impact of these obstacles on investment opportunities

description: The empirical relation between density and velocity of pedestrian movement is not completely analyzed, particularly with regard to the `microscopic' causes which determine the relation at medium and high densities. The simplest system for the investigation of this dependency is the normal movement of pedestrians along a line (single-file movement). This article presents experimental results for this system under laboratory conditions and discusses the following observations: The data show a linear relation between the velocity and the inverse of the density, which can be regarded as the required length of one pedestrian to move. Furthermore we compare the results for the single-file movement with literature data for the movement in a plane. This comparison shows an unexpected conformance between the fundamental diagrams, indicating that lateral interference has negligible influence on the velocity-density relation at the density domain $1 m^{-2}

Their structures were established mainly by NMR and MS experiments as well as the necessary chemical evidences. Their inhibitory effects on two organic anion transporters (OAT1 and OAT3) were investigated and the results showed that 1 exhibited a strongly specific inhibitory effect on OAT1 at 100 μM.
Measuring the Sun's Motion with Stellar Streams

description: We present a method for measuring the Sun's motion using the proper motions of Galactic halo star streams. The method relies on the fact that the motion of the stars perpendicular to a stream from a low-mass progenitor is close to zero when viewed from a non-rotating frame at rest with respect to the Galaxy, and that the deviation from zero is due to the reflex motion of the observer. The procedure we implement here has the advantage of being independent of the Galactic mass distribution. We run a suite of simulations to test the algorithm we have developed, and find that we can recover the input Solar motion to good accuracy with data of the quality that will soon become available from the ESA/Gaia mission.

description: In dance, a jump generally refers to a spring or a leap into the air. It is a combination movement that involves both a bend and a stretch of the legs—two movements that are fundamental to the Western theatrical tradition. But the technology of jumping suggests much more than just this practical sense. It suggests a negotiation of temporalities (as in, my jump follows my stretch, which is preceded by my bend) as well as the demonstration of the particular conditions necessary for becoming (as in, I can only jump because I have stretched, and stretch because I have bent). As such, jumping might also be understood as both an exercise and embodiment of choreographic thinking; as the activity of thought as it matters—and is made perceptible—in, through, and with its technology.
Two Bounds on the Maximum Phonon-Mediated Superconducting Transition Temperature

Year: 2006
Subjects: subject: Superconductivity (cond-mat.supr-con)

description: Two simple bounds on the $T_c$ of conventional, phonon-mediated superconductors are derived within the framework of Eliashberg theory in the strong coupling regime. The first bound is set by the total electron-phonon coupling available within a material given the hypothetical ability to arbitrarily dope the material. This bound is studied by deriving a generalization of the McMillan-Hopfield parameter, $\widetildeη(E)$, which measures the strength of electron-phonon coupling including anisotropy effects and rigid-band doping of the Fermi level to $E$. The second bound is set by the softening of phonons to instability due to strong electron-phonon coupling with electrons at the Fermi level. We apply these bounds to some covalent superconductors including MgB$_2$, where $T_c$ reaches the first bound, and boron-doped diamond, which is far from its bounds.

description: Functional supramolecular organogels with unique properties and morphology can be obtained by designing gelators’s chemical structure. Rosin, an important natural renewable diterpene resource, consists of a rigid ring skeleton and chiral structure similar to triterpenoids and has excellent self-assembly ability in solution. In this paper, four novel rosin-based derivatives were proposed and synthesized in one step by introducing phosphamide groups by using natural rosin as raw material. They could form eleven types of monoamide and diamide organogels in specific solvents. The minimum gelatinization concentration is 50–180 mg/mL. In particular, by adjusting the number and type of phosphamide groups and rigid structures, the morphology and other properties of the gel could be modulated. Two-dimension lamellar and three-dimensional fiber network organogels were obtained and the hydrogen bond and π–π stack were proved to be the most important driving forces for the gelation. What is particularly important is that the gels exhibited multiple stimulus responsiveness, such as temperature, acid-base and anions. Thus, the four dehydroabietylamine phosphamide gelators synthesized by the one-step method provide new ways of designing novel gel-based soft materials for intelligent response, ion detection, etc.

description: We propose $N=2$ holomorphic Yang-Mills theory on compact Kähler manifolds and show that there exists a simple mapping from the $N=2$ topological Yang-Mills theory. It follows that intersection parings on the moduli space of Einstein-Hermitian connections can be determined by examining the small coupling behavior of the $N=2$ holomorphic Yang-Mills theory. This paper is a higher dimensional generalization of the Witten's work on physical Yang-Mills theory in two dimensions.

description: This study assessed the evolution in sanitary services and water quality in the watershed of Santos and São Vicente Estuary from 2004 onwards. Results show evolution in services offered to the population after conclusion of the first phase of Onda Limpa Program, when sewage treated at the secondary level evolved from 11% to 14% of population, the pre-conditioning followed by submarine outfall 49% to 53% and population without a sewerage system fell 40% to 33%, being that for the latter 41% are in irregular areas not subjected to coverage. Among the four most populous sub-basins, each has about 90,000 people without a sewerage system, including urbanized and irregular areas. This factor, added to high level of annual rainfall still harms the water quality on the region.

Graviton multi-point amplitudes for higher-derivative gravity in anti-de Sitter space

description: We calculate graviton multi-point amplitudes in an anti-de Sitter black brane background for higher-derivative gravity of arbitrary order in numbers of derivatives. The calculations are performed using tensor graviton modes in a particular regime of comparatively high energies and large scattering angles. The regime simplifies the calculations but, at the same time, is well suited for translating these results into the language of the dually related gauge theory. After considering theories of up to eight derivatives, we generalize to even higher-derivative theories by constructing a "basis" for the relevant scattering amplitudes. This construction enables one to find the basic form of the n-point amplitude for arbitrary n and any number of derivatives. Additionally, using the four-point amplitudes for six and eight-derivative gravity, we re-express the scattering properties in terms of the Mandelstam variables.

Inhomogeneous Chemical Evolution of the Galactic Halo: Abundance of r-process Elements

description: We present a stochastic model based on the Monte Carlo technique to study the inhomogeneous chemical evolution of the Galactic halo. In particular, we consider the local enrichment and subsequent mixing of the interstellar gas resulting from bursts of star formation, following explicitly the fragmentation and coalescence of interstellar gas clouds. The model takes into account the mixing of halo gas through cloud-cloud collisions and the delayed mixing of supernova ejecta into the interstellar medium. The consequences of the infall of halo gas onto the Galactic disk are also discussed. The mass spectrum of clouds, the age-metallicity relation, and the G-dwarf distribution are investigated at different times. We analyze in detail the predictions of our model for the abundance of elements like Eu, Ba, and Sr in the Galactic halo, following their production by $r$-process nucleosynthesis for different assumptions on the supernova mass range. Finally, we compare our results with spectroscopic data for the chemical composition of metal-poor halo stars.

description: We show that liquid organic scintillator detectors (e.g., KamLAND and Borexino) can measure the 8B solar neutrino flux by means of the nu_e charged current interaction with the 13C nuclei naturally contained in the scintillators. The neutrino events can be identified by exploiting the time and space coincidence with the subsequent decay of the produced 13N nuclei. We perform a detailed analysis of the background in KamLAND, Borexino and in a possible liquid scintillator detector at SNOLab, showing that the 8B solar neutrino signal can be extracted with a reasonable uncertainty in a few years of data taking. KamLAND should be able to extract about 18 solar neutrino events from the already collected data. Prospects for gigantic scintillator detectors (such as LENA) are also studied.

description: The formation and growth of helium bubbles due to self-irradiation in plutonium has been modelled by a discrete kinetic equations for the number densities of bubbles having $k$ atoms. Analysis of these equations shows that the bubble size distribution function can be approximated by a composite of: (i) the solution of partial differential equations describing the continuum limit of the theory but corrected to take into account the effects of discreteness, and (ii) a local expansion about the advancing leading edge of the distribution function in size space. Both approximations contribute to the memory term in a close integrodifferential equation for the monomer concentration of single helium atoms. The present boundary layer theory for discrete equations is compared to the numerical solution of the full kinetic model and to previous approximation of Schaldach and Wolfer involving a truncated system of moment equations.

description: We describe a compact THz-pump and X-ray-probe beamline, based on an electron linac, for ultrafast time-resolved diffraction applications. Two high-energy electron ($γ>50$) bunches, $5~$ns apart, impinge upon a single-foil or a multifoil radiator and generate THz radiation and X-rays simultaneously. The THz pulse from the first bunch is synchronized to the X-ray beam of the second bunch by using an adjustable optical delay of THz pulse. The peak power of THz radiation from the multifoil radiator is estimated to be $0.14~$GW for a $200~$pC well-optimized electron bunch. GEANT4 simulations show a carbon foil with thickness of $0.5~-~1.0~$mm has the highest yield of $10~-~20~$keV hard X-rays for a $25~$MeV beam, which is approximately $10^3$ photons/(keV pC-electrons) within a few degrees of the polar angle. A carbon multifoil radiator with $35$ foils ($25~$$μm~$thick each) can generate close to $10^3$ hard X-rays/(keV pC-electrons) within a $2^\circ$ acceptance angle. With $200~$pC charge and $100~$Hz repetition rate, we can generate $10^7$ X-rays per $1~$keV energy bin per second or $10^5$ X-rays per $1~$keV energy bin per pulse. The longitudinal time profile of X-ray pulse ranges from $400~-~600~$fs depending on the acceptance angle. The broadening of the time duration of X-ray pulse is observed owing to its diverging effect. A double-crystal monochromator (DCM) will be used to select and transport the desired X-rays to the sample. The heating of the radiators by an electron beam is negligible because of the low beam current.
