description: We report strategies of achieving both high assembly yield of carbon nanotubes at selected position of the circuit via dielectrophoresis (DEP) and field effect transistor (FET) yield using semiconducting enriched single walled carbon nanotube (s-SWNT) aqueous solution. When the DEP parameters were optimized for the assembly of individual s-SWNT, 97% of the devices show FET behavior with a maximum mobility of 210 cm2/Vs, on-off current ratio ~ 106 and on conductance up to 3 μS, however with an assembly yield of only 33%. As the DEP parameters were optimized so that 1-5 s-SWNTs are connected per electrode pair, the assembly yield was almost 90% with ~ 90% of these assembled devices demonstrating FET behavior. Further optimization gives an assembly yield of 100% with up to 10 SWNT/site, however with a reduced FET yield of 59%. Improved FET performance including higher current on-off ratio and high switching speed were obtained by integrating a local Al2O3 gate to the device. Our 90% FET with 90% assembly yield is the highest reported so far for carbon nanotube devices. Our study provides a pathway which could become a general approach for the high yield fabrication of CMOS compatible carbon nanotube FETs.

description: Protostellar feedback, both radiation and bipolar outflows, dramatically affects the fragmentation and mass accretion from star-forming cores. We use ORION, an adaptive mesh refinement gravito-radiation-hydrodynamics code, to simulate the formation of a cluster of low-mass stars, including both radiative transfer and protostellar outflows. We ran four simulations to isolate the individual effects of radiation feedback and outflow feedback as well as the combination of the two. Outflows reduce protostellar masses and accretion rates each by a factor of three and therefore reduce protostellar luminosities by an order of magnitude. Thus, while radiation feedback suppresses fragmentation, outflows render protostellar radiation largely irrelevant for low-mass star formation above a mass scale of 0.05 M_sun. We find initial fragmentation of our cloud at half the global Jeans length, ~ 0.1 pc. With insufficient protostellar radiation to stop it, these 0.1 pc cores fragment repeatedly, forming typically 10 stars each. The accretion rate in these stars scales with mass as predicted from core accretion models that include both thermal and turbulent motions. We find that protostellar outflows do not significantly affect the overall cloud dynamics, in the absence of magnetic fields, due to their small opening angles and poor coupling to the dense gas. The outflows reduce the mass from the cores by 2/3, giving a core to star efficiency ~ 1/3. The simulation with radiation and outflows reproduces the observed protostellar luminosity function. All of the simulations can reproduce observed core mass functions, though they are sensitive to telescope resolution. The simulation with both radiation and outflows reproduces the galactic IMF and the two-point correlation function of the cores observed in rho Oph.

description: I briefly review the current state of the modelling of photospheric activity based on the high-precision optical light curves obtained with MOST, CoRoT, and Kepler. These models can be used to search for active longitudes where activity is preferentially concentrated, estimate the amplitude of stellar differential rotation, and look for short-term activity cycles as, e.g., in the case of CoRoT-2. In the case of a late-type star accompanied by a transiting hot Jupiter, the small light modulations observed during transits when a dark spot is occulted by the disc of the planet are also briefly considered. They can be used to derive information on individual active regions as well as on stellar rotation and the spin-orbit alignment of the system.

The adaption method is inspired by mutually unbiased measurements, but it is also applicable in cases for which no complete set of mutually unbiased bases is known.

description: Ground-based surveys have mapped the stellar outskirts of Local Group galaxies in unprecedented detail, but extending this work to other galaxies is necessary to overcome stochastic variations in evolutionary history and provide more stringent constraints on cosmological galaxy formation models. As part of our continuing program of ultra-deep imagery of galaxies beyond the Local Group, we present a wide-field analysis of the isolated late-type spiral NGC2403 using data obtained with Suprime-Cam on Subaru. The survey reaches a maximum projected radius of 30 kpc or deprojected radius of R_dp~60 kpc. The colour-magnitude diagram reaches 1.5 mag below the tip of the metal-poor red giant branch (RGB) at a completeness rate > 50% for R_dp >12 kpc. Using the combination of diffuse light photometry and resolved star counts, we are able to trace the radial surface brightness (SB) profile over a much larger range of radii and surface brightness than is possible with either technique alone. The exponential disc as traced by RGB stars dominates the SB profile out to >8 disc scale-lengths, or R_dp~18 kpc, and reaches a V-band SB of 29 mag per sq. arcsec. Beyond this radius, we find evidence for an extended structural component with a significantly flatter SB profile than the inner disc and which we trace to R_dp~40 kpc and ~32 mag per sq. arcsec. This component can be fit with a power-law index of ~3, has an axial ratio consistent with that of the inner disc and has a V-band luminosity of 1-7% that of the whole galaxy. At R_dp~20 - 30 kpc, we estimate a peak metallicity [M/H]= -1.0+/-0.3. Although the extant data are unable to discriminate between stellar halo or thick disc interpretations of this component, our results support the notion that faint, extended stellar structures are a common feature of all disc galaxies, even isolated, low-mass systems.

description: The electronic band structure of cubic HfO2 is calculated using an it ab initio all-electron self--consistent linear augmented plane-wave method, within the framework of the local-density approximation and taking into account full-relativistic contributions. From the band structure, the carrier effective masses and the complex dielectric function are obtained. The Γ-isotropic heavy and light electron effective masses are shown to be several times heavier than the electron tunneling effective mass measured recently. The imaginary part of the complex dielectric function ε_2(ω) is in good agreement with experimental data from ultraviolet spectroscopic ellipsometry measurements in bulk yttria-stabilized HfO2 as well as with those performed in films deposited with the tetrakis diethylamido hafnium precursor for energies smaller than 9.5 eV.

description: A web based survey is an effective tool which is used frequently in academic and non academic researches. Increase in internet usage and easy access to web technology facilitate the growing popularity of web surveys but absence of exhaustive literature on web surveys presents a significant challenge. This paper presents basic guidelines for developing a robust web survey. Aspects related to data quality, coverage bias, questionnaire design, non response bias, response bias, processing error, data duplication and pilot testing are discussed in detail. The paper closes with suggestions on key areas in which advance research is required to enhance the data quality of web questionnaires.

description: Domain-wall skyrmions (DWSKs) are topological spin textures confined within domain walls that have recently attracted significant attention due to their potential applications in racetrack memory technologies. In this study, we theoretically investigated the motion of DWSKs driven by spin-polarized currents in ferromagnetic strips. Our findings reveal that the motion of DWSKs is contingent upon the direction of the current. When the current is applied parallel to the domain wall, both spin-transfer torque (STT) and spin-orbit torque (SOT) can drive the DWSK along the domain wall. Conversely, for currents applied perpendicular to the domain wall, STT can induce DWSK motion by leveraging the skyrmion Hall effect as a driving force, whereas SOT-driven DWSKs halt their motion after sliding along the domain wall. Furthermore, we demonstrated the current-driven motion of DWSKs along curved domain walls and proposed a racetrack memory architecture utilizing DWSKs. These findings advance the understanding of DWSK dynamics and provide insights for the design of spintronic devices based on DWSKs.

Isotropy testing in spatial point patterns: nonparametric versus parametric replication under misspecification

description: Several hypothesis testing methods have been proposed to validate the assumption of isotropy in spatial point patterns. A majority of these methods are characterised by an unknown distribution of the test statistic under the null hypothesis of isotropy. Parametric approaches to approximating the distribution involve simulation of patterns from a user-specified isotropic model. Alternatively, nonparametric replicates of the test statistic under isotropy can be used to waive the need for specifying a model. In this paper, we first present a general framework which allows for the integration of a selected nonparametric replication method into isotropy testing. We then conduct a large simulation study comprising application-like scenarios to assess the performance of tests with different parametric and nonparametric replication methods. In particular, we explore distortions in test size and power caused by model misspecification, and demonstrate the advantages of nonparametric replication in such scenarios.

description: We explore the accretion mechanisms in EX Lupi, prototype of EXor variables, during its quiescence and outburst phases. We analyse high-resolution optical spectra taken before, during, and after its 2008 outburst. In quiescence and outburst, the star presents many permitted emission lines, including typical CTTS lines and numerous neutral and ionized metallic lines. During the outburst, the number of emission lines increases to over a thousand, with narrow plus broad component structure (NC+BC). The BC profile is highly variable on short timescales (24-72h). An active chromosphere can explain the metallic lines in quiescence and the outburst NC. The dynamics of the BC line profiles suggest an origin in a hot, dense, non-axisymmetric, and non-uniform accretion column that suffers velocity variations along the line-of-sight on timescales of days. Assuming Keplerian rotation, the emitting region would be located at ~0.1-0.2 AU, consistent with the inner disk rim, but the velocity profiles of the lines reveal a combination of rotation and infall. Line ratios of ions and neutrals can be reproduced with a temperature of T~6500 K for electron densities of a few times 10$^{12}$cm$^{-3}$ in the line-emitting region. The data confirm that the 2008 outburst was an episode of increased accretion, albeit much stronger than previous EX Lupi and typical EXors outbursts. The line profiles are consistent with the infall/rotation of a non-axisymmetric structure that could be produced by clumpy accretion during the outburst phase. A strong inner disk wind appears in the epochs of higher accretion. The rapid recovery of the system after the outburst and the similarity between the pre-outburst and post-outburst states suggest that the accretion channels are similar during the whole period, and only the accretion rate varies, providing a superb environment for studying the accretion processes.

description: In his 1979 paper Trotman proves, using the techniques of the Thom transversality theorem, that under some conditions on the dimensions of the manifolds under consideration, openness of the set of maps transverse to a stratification in the strong (Whitney) topology implies that the stratification is $(a)$-regular. Here we first discuss the Thom transversality theorem for the weak topology and then give a similiar kind of result for the weak topology, under very weak hypotheses. Recently several transversality theorems have been proved for complex manifolds and holomorphic maps. In view of these transversality theorems we also prove a result analogous to Trotman's result in the complex case.

We review theoretical calculations for the breaking of flavor symmetry, quark-antiquark symmetry and charge symmetry in the unpolarized and polarized nucleons using the meson cloud model. We report an estimation for the total distribution of strange and antistrange quarks in the nucleon by combining theoretical calculations of SU(3) flavor symmetry breaking with light antiquark distributions obtained from global analysis of available experimental data.

Rapid Transition of Uncombed Penumbrae to Faculae during Large Flares

description: In the past two decades, the complex nature of sunspots has been disclosed with high-resolution observations. One of the most important findings is the "uncombed" penumbral structure, where a more horizontal magnetic component carrying most of Evershed Flows is embedded in a more vertical magnetic background (Solanki & Montavon 1993). The penumbral bright grains are locations of hot upflows and dark fibrils are locations of horizontal flows that are guided by nearly horizontal magnetic field. On the other hand, it was found that flares may change the topology of sunspots in $δ$ configuration: the structure at the flaring polarity inversion line becomes darkened while sections of peripheral penumbrae may disappear quickly and permanently associated with flares (Liu et al. 2005). The high spatial and temporal resolution observations obtained with Hinode/ SOT provide an excellent opportunity to study the evolution of penumbral fine structure associated with major flares. Taking advantage of two near-limb events, we found that in sections of peripheral penumbrae swept by flare ribbons, the dark fibrils completely disappear, while the bright grains evolve into faculae that are signatures of vertical magnetic flux tubes. The corresponding magnetic fluxes measured in the decaying penumbrae show stepwise changes temporally correlated with the flares. These observations suggest that the horizontal magnetic field component of the penumbra could be straightened upward (i.e., turning from horizontal to vertical) due to magnetic field restructuring associated with flares, which results in the transition of penumbrae to faculae.

We find good agreement between our simulations and the atom-loss measurements with a $^{39}$K condensate. Our simulations reveal an interplay of weak collapse and the propensity of the system to form a hotspot, and we uncover new scaling laws that govern this behavior. We also identify promising signatures of the theoretically predicted, but so far experimentally elusive, elastic three-body interactions.

description: Cosmic rays are a known problem in astronomy, causing both loss of data and data inaccuracy. The problem becomes even more extreme when considering data from a high-radiation environment, such as in orbit around Earth or outside the Earth's magnetic field altogether, unprotected, as will be the case for the James Webb Space Telescope (JWST). For JWST, all the instruments employ nondestructive readout schemes. The most common of these will be "up the ramp" sampling, where the detector is read out regularly during the ramp. We study three methods to correct for cosmic rays in these ramps: a two-point difference method, a deviation from the fit method, and a y-intercept method. We apply these methods to simulated nondestructive read ramps with single-sample groups and varying combinations of flux, number of samples, number of cosmic rays, cosmic-ray location in the exposure, and cosmic-ray strength. We show that the y-intercept method is the optimal detection method in the read-noise-dominated regime, while both the y-intercept method and the two-point difference method are best in the photon-noise-dominated regime, with the latter requiring fewer computations.

On the sodium overabundance of giants in open clusters: The case of the Hyades
Creators: name: Smiljanic, Rodolfo
Publisher: name: arXiv
Year: 2012
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)
subject: FOS: Physical sciences

description: Sodium abundances have been determined in a large number of giants of open clusters but conflicting results, ranging from solar values to overabundances of up to five orders of magnitude, have been found. The reasons for this disagreement are not well-understood. As these Na overabundances can be the result of deep mixing, their proper understanding has consequences for models of stellar evolution. As discussed in the literature, part of this disagreement comes from the adoption of different corrections for non-LTE effects and from the use of different atomic data for the same set of lines. However, a clear picture of the Na behaviour in giants is still missing. To contribute in this direction, this work presents a careful redetermination of the Na abundances of the Hyades giants, motivated by the recent measurement of their angular diameters. An average of [Na/Fe] = +0.30, in NLTE, has been found. This overabundance can be explained by hydrodynamical models with high initial rotation velocities. This result, and a trend of increasing Na with increasing stellar mass found in a previous work, suggests that there is no strong evidence of Na overabundances in red giants beyond those values expected by evolutionary models of stars with more than ~ 2 Msun.

description: We present a multiwavelength study of the NGC 281 complex which contains the young cluster IC 1590 at the center, using deep wide-field optical UBVI_c photometry, slitless spectroscopy along with archival data sets in the near-infrared (NIR) and X-ray. The extent of IC 1590 is estimated to be ~6.5 pc. The cluster region shows a relatively small amount of differential reddening. The majority of the identified young stellar objects (YSOs) are low mass PMS stars having age <1-2 Myr and mass 0.5-3.5 M_\odot. The slope (Γ) of the mass function for IC 1590, in the mass range 2 < M/M_\odot \le 54, is found to be -1.11+-0.15. The slope of the K-band luminosity function (0.37+-0.07) is similar to the average value (~0.4) reported for young clusters. The distribution of gas and dust obtained from the IRAS, CO and radio maps indicates clumpy structures around the central cluster. The radial distribution of the young stellar objects, their ages, Δ(H-K) NIR-excess, and the fraction of classical T Tauri stars suggest triggered star formation at the periphery of the cluster region. However, deeper optical, NIR and MIR observations are needed to have a conclusive view of star formation scenario in the region. The properties of the Class 0/I and Class II sources detected by using the Spitzer mid-infrared observations indicate that a majority of the Class II sources are X-ray emitting stars, whereas X-ray emission is absent from the Class 0/I sources. The spatial distribution of Class 0/I and Class II sources reveals the presence of three sub-clusters in the NGC 281 West region.

description: Copying, Creativity and Copyright – by Professor Ronan Deazley (Queen’s University Belfast) and CREATe researcher Bartolomeo Meletti – offers insights into the creative process behind their award-winning film The Adventure of the Girl with the Light Blue Hair, and makes the case for understanding copying as a positive phenomenon in helping us learn and innovate, develop and engage with others. Copying plays a crucial role at all stages of our development as human beings, from DNA replication to the way in which physical synchronicity helps us establish connections and relationships with friends and family, and beyond. Copying can also facilitate freedom of expression and political engagement, by enabling people and communities across the globe come together and speak with one voice. Consider, for example the global response to the killings in Paris at the offices of the Charlie Hebdo magazine on 7 January 2015. Three simple words – Je Suis Charlie – have been copied (creatively and otherwise) and re-copied millions of times all over the world to commemorate those who lost their lives during that attack. This is copying as remembrance, free speech, solidarity and protest.

description: This report summarizes the November 21 - December 6, 2009 cruise on the RSS Discovery involving full-water-column CTD and lowered ADCP profiles, along with shipboard ADCP profiles, conducted within the Northwest Providence Channel and east of Abaco Island, Bahamas. No Florida Straits sections were planned due to the RRS Discovery not having clearances to enter U.S. waters. A package consisting of a Seabird Electronics Model 9/11+ CTD O2 system, a RDI 150 kHz Workhorse Lowered Acoustic Doppler Current Profiler, a RDI 300 kHz Workhorse Lowered Acoustic Doppler Current Profiles, and 23 10-liter Niskin bottles, was to be lowered to the bottom. This report includes a description of the calibrations procedures and profiles of pressure, salinity (conductivity), temperature, and dissolved oxygen concentration. Water samples were also collected at various depths and analyzed for salinity and oxygen concentration to aid with CTD calibration. A total of 35 CTD-O2/LADCP stations were occupied. PIES/CPIES operations were conducted from 5 sites, involving recovery, deployment and telemetry. Mooring operations include recovery and redeployment of 3 moorings with a mixture of current meters, Acoustic Doppler Current Profiles (ADCPs), and temperature/salinity recorders, and deployment of 2 bottom landers instrumented with bottom pressure recorders.

description: The increasing availability of longitudinal student achievement data has heightened interest among researchers, educators and policy makers in using these data to evaluate educational inputs, as well as for school and possibly teacher accountability. Researchers have developed elaborate "value-added models" of these longitudinal data to estimate the effects of educational inputs (e.g., teachers or schools) on student achievement while using prior achievement to adjust for nonrandom assignment of students to schools and classes. A challenge to such modeling efforts is the extensive numbers of students with incomplete records and the tendency for those students to be lower achieving. These conditions create the potential for results to be sensitive to violations of the assumption that data are missing at random, which is commonly used when estimating model parameters. The current study extends recent value-added modeling approaches for longitudinal student achievement data Lockwood et al. [J. Educ. Behav. Statist. 32 (2007) 125--150] to allow data to be missing not at random via random effects selection and pattern mixture models, and applies those methods to data from a large urban school district to estimate effects of elementary school mathematics teachers. We find that allowing the data to be missing not at random has little impact on estimated teacher effects. The robustness of estimated teacher effects to the missing data assumptions appears to result from both the relatively small impact of model specification on estimated student effects compared with the large variability in teacher effects and the downweighting of scores from students with incomplete data.

description: Background

Nucleolar organizer regions are parts of chromosomes that code ribosomal RNA and correlate to cellular proliferation. They have been identified by means of an argyrophilic technique that reveals NORs as black dots in the nuclei. The method has been recently applied in some malignancies, as lymphoma or melanoma. Only few investigations on  hormonal-dependent tumours have been published. Our aim was to investigate on the total number of AgNORs and cell type of endometrial tumors.

Material and Methods

We studied 21 cases of formalin fixed paraffin embedded endometrial tumors including hyperplasia. The number of AgNORs was counted in both epithelial and stromal components. A total of 13 cases were benign and 8 malignant lesions.

Results

The total number of AgNORs was found to correlate with mitotic counts both in benign lesions and malignancies. The mean number of AgNORs increased from 2.79 in simple endometrial hyperplasia to 10.0 in adenocarcinoma.

Conclusions

Our data indicate that the AgNORs visualization can assist to differentiate between different malignancy grades of endometrial proliferations, especially between complex endometrial hyperplasia and atypical hyperplasia as well as endometrial adenocarcinomas.

description: We recall a construction of non-commutative algebras related to a one-parameter family of (deformed) spheres and tori, and show that in the case of tori, the *-algebras can be completed into C*-algebras isomorphic to the standard non-commutative torus. As the former was constructed in the context of matrix (or fuzzy) geometries, it provides an important link to the framework of non-commutative geometry, and opens up for a concrete way to study deformations of non-commutative tori. Furthermore, we show how the well-known fuzzy sphere and fuzzy torus can be obtained as formal scaling limits of finite-dimensional representations of the deformed algebras, and their projective modules are described together with connections of constant curvature.

description: The idea of this study came out long time ago, in relation to some personal unfortunate events. I have extended my research on 10000 funerary inscriptions and documents from civil and military tombs to find out if the relation between the date of birth and the date of death  is significantly correlated . Our findings point out that in about 75% cases the date of death is up to 2 months before or after the date of birth. This suggests a genetic determinism of death moment.

Acoustic Emission of Lactococcus lactis ssp. lactis C2 Infected with Three Bacteriophages c2, sk1 and ml3

Subjects: subject: Food Microbiology

description: The objective of this research was to monitor the Acoustic Emission (AE) produced by Lactococcus lactis ssp. lactis C2 infected with three bacteriophages (c2, sk1 and ml3 at 90 min) using an acoustic emission-monitoring device which was designed at University of Kentucky in Lexington KY. The acoustic emission data was collected and then analyzed. These Acoustic Emission (AE) data suggested that bacteriophage ml3, sk1 and c2 can easily be distinguished by the differences in Absolute Energy (ABE), Centroid Frequency (CF) and Peak Frequency (PF) signals. The AE data suggested that bacteriophage sk1 and c2 caused greater stress on the lactis C2 than bacteriophage ml3. When the bacteriophage were added to the lactis C2 at 90 min, the host bacteria shifted from cell division processes to the development of bacteriophage replications. When the bacteriophage replications were initiated, the AE information being emitted increased significantly. The distinguishable difference produced by AE could provide a novel method to identify different bacteriophage and track certain metabolic and cell growth parameters of the host bacteria. Further research is still needed to identify where the AE information is being generated and whether all bacteriophage are as different as those used in this study.

numismatics

description: This thesis, a hybrid of traditional humanities scholarship and cultural heritage informatics, reflects technical advances in digital numismatics made between 2011 and 2013. In this regard, this thesis is intended both as a potential guide to contemporary curators and information technology professionals who desire to make their collections broadly available on the World Wide Web and as documentation of the state of digital numismatics in the year 2013. This aspect of documentation is particularly important since many earlier digital numismatic projects have gone unpublished. It is paramount to record the thought processes which have informed the intellectual and technical decisions made during the development of these projects for the benefit of future generations of scholars, curators, and information technologists.

description: We construct fermionic Lagrangians with anisotropic scaling z=2, the natural counterpart of the usual z=2 Lifshitz field theories for scalar fields. We analyze the issue of chiral symmetry, construct the Noether axial currents and discuss the chiral anomaly giving explicit results for two-dimensional case. We also exploit the connection between detailed balance and the dynamics of Lifshitz theories to find different z=2 fermionic Lagrangians and construct their supersymmetric extensions.

description: We prepared magnetic tunnel junctions with one ferromagnetic and one superconducting Al-Si electrode. Pure cobalt electrodes were compared with a Co-Fe-B alloy and the Heusler compound Co2FeAl. The polarization of the tunneling electrons was determined using the Maki-Fulde-model and is discussed along with the spin-orbit scattering and the total pair-breaking parameters. The junctions were post-annealed at different temperatures to investigate the symmetry filtering mechanism responsible for the giant tunneling magnetoresistance ratios in Co-Fe-B/ MgO/ Co-Fe-B junctions.

description: We study the electronic properties of actual-size graphene nanoribbons subjected to substitutional disorder particularly with regard to the experimentally observed metal-insulator transition. Calculating the local, mean and typical density of states, as well as the time-evolution of the particle density we comment on a possible disorder-induced localisation of charge carriers at and close to the Dirac point within a percolation transition scenario.

description: The electronic band structures and optical properties of cubic, tetragonal, and monoclinic phases of HfO2 are calculated using the first-principles linear augmented plane-wave method, within the density functional theory and generalized gradient approximation, and taking into account full-relativistic contributions. From the band structures, the electron- and hole-effective masses were obtained. Relativistic effects play an important role, which is reflected in the effective masses values and in the detailed structure of the dielectric function. The calculated imaginary part of the dielectric function and refractive index are in good agreement with the data reported in the literature.
THE ARABIC PARTICLES ‘INNA WA AḪAWĀTU-HĀ’ AT THE SYNTAX-SEMANTICS INTERFACE

description: In Arabic inna wa-aḫawātu-hā ‘inna and its related sisters’ are traditionally considered as verb-like particles. They are specified as introducing equational sentences and change their constituents’ case to a different pattern from what verbs do. Therefore, they are called nawāsiḫ in Arabic, or words that cause a shift to the accusative case (Ryding 2005).  The medieval grammarians’ treatment of inna and its sisters as verb-like particles and of the equational sentence in general is based on the theory of ‘amal, ‘government’ which Sībawayhi has described it in his book Al-kitab. The theory presumes a grammatical operation (‘amal) in which an operator (‘āmil) assigns to a unique operand (ma’mūl) a grammatical function (Carter, 1973, 151). However, in modern linguistics, government is realized as a syntactic relation that imposes case agreement between the syntactic elements in the sentential structure. And this structure has a deep representation and surface representation.  The Medieval treatment for the equational sentence introduced by inna is problematic, because it attributes to inna a verbal power to resolve the issue of the case assignment to the equational sentence which lacks an overt syntactic operator. Modern approaches to equational sentence differ totally from the traditional account. Some modern approaches propose a copula for the equational sentence; this copula is either covert or deleted. Other modern approaches propose a tense projection in deep structure that determines an equational sentence’s surface form. Neither sort of approach gives a reasonable explanation for the case assignment pattern, for the general properties of equational sentences, or for the status of inna.  In this study, I propose a new approach focusing on the role of semantics in the assignment of case in equational sentences in Arabic. My hypothesis is based on a new interpretation to Sībawayhi’s description of the ‘ibtida’ sentence; according to this new interpretation ibtida’ is not a syntactic operator but rather a semantic one. I also propose that a sentence’s syntactic properties are sensitive to its semantic MODE, a specification of whether it expresses a topic-based proposition; or an event-based proposition.  My new hypothesis is intended to apply to all varieties of Arabic including Classical Arabic, and Modern Standard Arabic, as well as the regional dialects of Arabic.
