Creators: name: Khan Farnia, Khan Farnia,Aboo BakarKhan,Mohammed Aslam Husin,Md Tabrez
Publisher: name: Zenodo
Year: 2023

description: The permanent magnet synchronous reluctance generator (PMSRG) is an innovative electrical machine that combines the benefits of both permanent magnet and reluctance torques. In recent times, the synchronous reluctance generator (PMSRG) has gained significant attention in the industry due to its unique characteristics. This study emphasizes the comprehensive analysis, modeling, and simulation of a PMSRG drive system, highlighting its distinguishing characters in comparison to other generators used in similar applications. By employing dynamic equations, the PMSRG's mathematical base is established, and the d-q transformation strategy is implemented for vector control. Space Vector Pulse Width Modulation (SVPWM) technology is utilized to model and simulate the PMSRG without rotor cage or magnetic material. The MATLAB Simulink environment is employed to simulate and customize the PMSRG model. This simulation takes into account speed variations under different frequencies and load conditions, further enhancing the understanding and potential of the PMSRG in practical applications. Apart from that this analysis also focuses on highlighting the distinctive features of the PMSRG, demonstrating its potential for improved energy conversion efficiency and reduced losses compared to traditional motors. These findings contribute to a better understanding and optimization of PMSRGs, making them a promising option for various industrial and renewable energy applications.

description: The Helmholtz equation can be written as coupled equations for the amplitude and phase. By considering spatial phase distributions corresponding to reflectionless wave propagation in the plane and solving for the amplitude in terms of this phase, we designed two-dimensional graded-index media which do not scatter light. We give two illustrative examples, the first of which is a periodic grating for which diffraction is completely suppressed at a single frequency at normal incidence to the periodicity. The second example is a medium which behaves as a 'beam shifter' at a single frequency; acting to laterally shift a plane wave, or sufficiently wide beam, without reflection.

description: The features of solitary waves observed in horizontal monodisperse chain of barely touching beads not only depend on geometrical and material properties of the beads but also on the initial perturbation provided at the edge of the chain. An impact of a large striker on a monodisperse chain, and similarly a sharp decrease of bead radius in a stepped chain, generates a solitary wave train containing many single solitary waves ordered by decreasing amplitudes. We find, by simple analytical arguments, that the unloading of compression force at the chain edge has a nearly exponential decrease. The characteristic time is mainly a function involving the grains' masses and the striker mass. Numerical calculations and experiments corroborate these findings.

description: The accretion flow around the Galactic Center black hole Sagittarius A* (Sgr A*) is expected to have an electron temperature that is distinct from the ion temperature, due to weak Coulomb coupling in the low-density plasma. We present four two-temperature general relativistic radiative magnetohydrodynamic (GRRMHD) simulations of Sgr A* performed with the code KORAL. These simulations use different electron heating prescriptions, motivated by different models of the underlying plasma microphysics. We compare the Landau-damped turbulent cascade model used in previous work with a new prescription we introduce based on the results of particle-in-cell simulations of magnetic reconnection. With the turbulent heating model, electrons are preferentially heated in the polar outflow, whereas with the reconnection model electrons are heated by nearly the same fraction everywhere in the accretion flow. The spectra of the two models are similar around the submillimetre synchrotron peak, but the models heated by magnetic reconnection produce variability more consistent with the level observed from Sgr A*. All models produce 230~GHz images with distinct black hole shadows which are consistent with the image size measured by the Event Horizon Telescope, but only the turbulent heating produces an anisotropic `disc-jet' structure where the image is dominated by a polar outflow or jet at frequencies below the synchrotron peak. None of our models can reproduce the observed radio spectral slope, the large near-infrared and X-ray flares, or the near-infrared spectral index, all of which suggest non-thermal electrons are needed to fully explain the emission from Sgr A*.

description: Big bang nucleosynthesis constraints on baryon isocurvature perturbations are determined. A simple model ignoring the effects of the scale of the perturbations is first reviewed. This model is then extended to test the claim that large amplitude perturbations will collapse, forming compact objects and preventing their baryons from contributing to the observed baryon density. It is found that baryon isocurvature perturbations are constrained to provide only a slight increase in the density of baryons in the universe over the standard homogeneous model. In particular it is found that models which rely on power laws and the random phase approximation for the power spectrum are incompatible with big bang nucleosynthesis unless an {\em ad hoc}, small scale cutoff is included.

description: In our previous works, we have analyzed the evolution of bulk viscous matter dominated universe with a more general form for bulk viscous coefficient, $ζ=ζ_{0}+ζ_{1}\frac{\dot{a}}{a}+ζ_{2}\frac{\ddot{a}}{\dot{a}}$ and also carried out the dynamical system analysis. We found that the model reasonably describes the evolution of the universe if the viscous coefficient is a constant. In the present work we are contrasting this model with the standard $Λ$CDM model of the universe using the Bayesian method. We have shown that, even though the viscous model gives a reasonable back ground evolution of the universe, the Bayes factor of the model indicates that, it is not so superior over the $Λ$CDM model, but have a slight advantage over it.

#FFBosworth
Before he became a famous leader in the charismatic movement, Ern Baxter was a campaign manager for William Branham. But something happened that prompted him to part ways with Branham. Baxter and F.F. Bosworth were two of the most prominent leaders to work with Branham.
This blog post features an interview of Baxter by the Rev. Dewey Friedel. It reveals, among other things, Baxter's serious concerns about Branham's doctrine and "supernatural" gift of healing. Baxter said he was "disturbed" by Branham's teachings on faith and he questioned the source of Branham's power. The interview is believed to have taken place in the early 1990s. It was published as a book titled, Life on Wings.

Existence of the LOFF State in Superconducting UPd_2Al_3

description: In a recent Letter, Gloos et al have suggested that the heavy fermion superconductor, UPd_2Al_3, has a transition in magnetic field from the normal state to an inhomogeneous superconducting state, known as the LOFF state, followed at lower fields by a first order phase transition to the usual flux lattice state. To investigate this, the author derives a formula for the upper critical field for the LOFF state valid at all temperatures in the clean limit (the previous work of Gruenberg and Gunther was restricted to zero temperature), and shows that the LOFF state cannot quantitatively explain the phase diagram for UPd_2Al_3. This indicates that a more general solution which breaks cylindrical symmetry is necessary to explain the data.

Regularised Kalb-Ramond Magnetic Monopole with Finite Energy

description: In a previous work we suggested a self-gravitating electromagnetic monopole solution in a string-inspired model involving global spontaneous breaking of a $SO(3)$ internal symmetry and Kalb-Ramond (KR) axions, stemming from an antisymmetric tensor field in the massless string multiplet. These axions carry a charge, which, in our model, also plays the rôle of the magnetic charge. The resulting geometry is close to that of a Reissner-Nordström (RN) black hole with charge proportional to the KR-axion charge. We proposed the existence of a thin shell structure inside a (large) core radius as the dominant mass contribution to the energy functional. The resulting energy was finite, and proportional to the KR-axion charge; however, the size of the shell was not determined and left as a phenomenological parameter. In the current article, we can calculate the mass-shell size, on proposing a regularisation of the black hole singularity via a matching procedure between the RN metric in the outer region and, in the inner region, a de Sitter space with a (positive) cosmological constant proportional to the scale of the spontaneous symmetry breaking of $SO(3)$ . The matching, which involves the Israel junction conditions for the metric and its first derivatives at the inner surface of the shell, determines the inner mass-shell radius. The axion charge plays an important rôle in guaranteeing positivity of the "mass coefficient" of the gravitational potential term appearing in the metric component; so the KR electromagnetic monopole shows normal attractive gravitational effects. This is to be contrasted with the global monopole case (in the absence of KR axions) where such a matching is known to yield a negative "mass coefficient" (and, hence, repulsive gravitational effects). The total energy of the monopole within the shell is calculated.

description: Aims: The two stable isotopes of nitrogen, 14N and 15N, exhibit a range of abundance ratios both inside and outside the solar system. The elemental ratio in the solar neighborhood is 440. Recent ALMA observations showed HCN/HC15N ratios from 83 to 156 in six T Tauri and Herbig disks and a CN/C15 N ratio of 323 +/- 30 in one T Tauri star. We aim to determine the dominant mechanism responsible for these enhancements of 15N: low-temperature exchange reactions or isotope-selective photodissociation of N2. Methods: Using the thermochemical code DALI, we model the nitrogen isotope chemistry in circumstellar disks with a 2D axisymmetric geometry. Our chemical network is the first to include both fractionation mechanisms for nitrogen. The model produces abundance profiles and isotope ratios for several key N-bearing species. We study how these isotope ratios depend on various disk parameters. Results: The formation of CN and HCN is closely coupled to the vibrational excitation of H2 in the UV-irradiated surface layers of the disk. Isotope fractionation is completely dominated by isotope-selective photodissociation of N2. The column density ratio of HCN over HC15N in the disk's inner 100 au does not depend strongly on the disk mass, the flaring angle or the stellar spectrum, but it is sensitive to the grain size distribution. For larger grains, self-shielding of N2 becomes more important relative to dust extinction, leading to stronger isotope fractionation. Between disk radii of ~50 and 200 au, the models predict HCN/HC15N and CN/C15N abundance ratios consistent with observations of disks and comets. The HCN/HC15N and CN/C15N column density ratios in the models are a factor of 2-3 higher than those inferred from the ALMA observations.

description: We present the first extraction of the transversity distribution in the framework of collinear factorization based on the global analysis of pion-pair production in deep-inelastic scattering off transversely polarized targets and in proton-proton collisions with one transversely polarized proton. The extraction relies on the knowledge of di-hadron fragmentation functions, which are taken from the analysis of electron-positron annihilation data. For the first time, the chiral-odd transversity is extracted from a global analysis similar to what is usually done for the chiral-even spin-averaged and helicity distributions. The knowledge of transversity is important for, among other things, detecting possible signals of new physics in high-precision low-energy experiments.

description: A model has been proposed in which neutral scalar particles chi, of mass 1-10 MeV, annihilate through the exchange of a light vector boson U, of mass 10-100 MeV, to produce the 511 keV line observed emanating from the center of the galaxy. The chi interacts weakly with normal matter and is a viable dark matter candidate. If the U-boson couples to quarks as well as to electrons, it could enhance the branching ratio for the rare decay pi0 -> e+e-. A recent measurement by the KTeV Collaboration lies three standard deviations above a prediction by Dorokhov and Ivanov, and we relate this excess to the couplings of the U-boson. The values are consistent with other constraints and considerations. We make some comments on possible improvements in the data.

The spaces forming the Fréchet part (i.e. the space of test functions) of the triple are characterized both in a geometric way and in terms of the adjoint of multiplication by the complex variable, using the Stirling numbers of the second kind. The dual of the space of test functions has a topological algebra structure, of the kind introduced and studied by the first named author and G. Salomon.

description: Ende 2019 hat sich das Coronavirus weltweit verbreitet, mit den ersten Fällen in der Schweiz im Februar 2020 (BAG, 2020) und der Erklärung zur Pandemie durch die WHO im darauffolgenden März (WHO, 2022). Durch die Covid-19-Pandemie wurde das Schweizer Gesundheitswesen in verschiedener Hinsicht auf die Probe gestellt. Einerseits musste innert kurzer Zeit eine Vielzahl intensivpflegebedürftiger Patientinnen und Patienten aufgrund einer noch unbekannten Viruserkrankung behandelt werden. Andererseits wurden, um deren adäquate Versorgung zu garantieren, die nicht durch Covid-19 bedingten Behandlungen reduziert. So galt zwischen dem 16. März und dem 26. April 2020 («Frühlings-Lockdown») im Rahmen der ausserordentlichen Lage für Spitäler schweizweit ein Verbot für «medizinisch nicht dringend angezeigte Untersuchungen und Behandlungen» («temporäres Behandlungsverbot») (Bundesrat, 2020). Aufgrund der tatsächlichen oder antizipierten Auslastung der Intensivstationen mussten Spitäler auch nach dem Frühlings-Lockdown phasenweise Eingriffe verschieben.

Wichtigste Ergebnisse
Schweizweit reduzierten sich die stationären Fallzahlen während des Frühlings-Lockdowns 2020 im Vergleich zur Vorjahresperiode um 32,2%. Diese Reduktion wurde mit Ausnahme einzelner Eingriffe bis Ende 2020 nicht kompensiert. Auf das ganze Jahr 2020 betrachtet wurden in den Schweizer Spitälern 5,8% weniger stationäre Fälle behandelt als 2019.

Der Rückgang der Fallzahlen während des Frühlings-Lockdowns war bei nicht-lebensnotwendigen Eingriffen und in Diagnosegruppen mit vielen elektiven Eingriffen am grössten, was zeigt, dass das Verbot für «medizinisch nicht dringend
angezeigte Untersuchungen und Behandlungen» wirksam umgesetzt wurde.

Im Tessin waren die Auswirkungen der Pandemie auf den regulären Spitalbetrieb früher festzustellen und die Reduktion der Fallzahlen war stärker als in den übrigen Grossregionen.

description: `Tree pruning' (TP) is an algorithm for probabilistic inference on binary Markov random fields. It has been recently derived by Dror Weitz and used to construct the first fully polynomial approximation scheme for counting independent sets up to the `tree uniqueness threshold.' It can be regarded as a clever method for pruning the belief propagation computation tree, in such a way to exactly account for the effect of loops. In this paper we generalize the original algorithm to make it suitable for decoding linear codes, and discuss various schemes for pruning the computation tree. Further, we present the outcomes of numerical simulations on several linear codes, showing that tree pruning allows to interpolate continuously between belief propagation and maximum a posteriori decoding. Finally, we discuss theoretical implications of the new method.

description: It is commonly believed that the significant energy saving advantages are belonged to the logic circuits which operate at low temperature as less enegy is needed for cooling them to the treshold temperature after operation. Also, nanoscale thermal management, efficient energy usage in nanoscale and especially thermal optimization are the most challenging issues, while dealing with the new generation of transistors as the miniaturizing unlimitedly the silicon channels of the transistors has resulted in an increase in the energy consumption of computers and the leakage currents. In this paper, the non-Fourier thermal attitudes of well-known two-dimensional crystalline materials of graphene, blue phosphorene, germanene, silicene and MoS$_2$ as the silicon channels replacements are studied by using the phonon Monte-Carlo method. We show that graphene and blue phosphorene have the least maximum temperature, representer of the reliability of the transistors, among the all five investigated nano-channels during the Monte-Cralo simulation. The established hotspots of these two materials are always cooler, not reaching the temperature threshold level, and they lose the heat much faster as the heat generation zone is switched off. The obtained results considered along with the electrical disadvantages of the graphene layer, suggests the blue phosphorene as the more thermally appropriate and optimal choice for the silicon channel replacement in new designed field effect transistors. That is to say that the limit of the energy and economic cost of the producing the advanced blue phosphorene chips meets the value of the product for the computing enterprise.

description: We study theoretically the Josephson current-phase relationship in a chaotic quantum dot coupled to superconductors by ballistic contacts. In this regime, strong proximity effect induces superconductivity in the quantum dot that leads to a significant modification in the electron density of states and formation of multiple sub-gaps. The magnitude of the resulting supercurrent depends on the phase difference of the superconducting order parameter in the leads and shows strongly anharmonic skewed behavior. We find that when the Thouless energy on the dot exceeds the superconducting energy gap, the second harmonic of the supercurrent becomes comparable in magnitude to the first harmonic. To address these effects on the technical level, we use the nonlinear $σ$-model Keldysh formalism in the framework of the circuit theory to compute dependence of the density of states, Josephson energy, and current on the superconducting phases in the leads. We analyze how these quantities change as a function of the Thouless energy and the superconducting gap. Finally, we briefly discuss sub-gap tail states, mesoscopic supercurrent fluctuations, weak localization correction, and also touch on anharmonicity of gatemon qubits with quantum dot Josephson junctions.

Es ist daher lohnend Öffentliche Bibliotheken in die angestrebte kommunale Gesamtstrategie zur Verbesserung von Gesundheit und Gesundheitschancen einzubeziehen. Aktuell unterbleibt in Deutschland jedoch größtenteils die kontinuierliche und flächendeckende Einbindung Öffentlicher Bibliotheken in integrierte Handlungskonzepte der Gesundheitsförderung. Relevante Hintergründe und Chancen werden aufgezeigt.

Density Waves in the Flows of Granular Media
Creators: name: Lee, Jysoo
Publisher: name: arXiv
Year: 1993
Subjects: subject: Condensed Matter (cond-mat)
subject: FOS: Physical sciences

description: We study density waves in the flows of granular particles through vertical tubes and hoppers using both analytic methods and molecular dynamics (MD) simulations. We construct equations of motion for quasi one-dimensional systems. The equations, combined with the Bagnold's law for friction, are used to describe the time evolutions of the density and the velocity fields for narrow tubes and hoppers. The solutions of the equations can have two types of density waves, kinetic and dynamic. For tubes, we can show the existence of kinetic waves, and obtain the condition for dynamic waves for tubes from the equations. For hoppers, we obtain the solutions of the equations up to the first order of the opening angle, which also show the existence of kinetic waves. We reproduce density waves in the MD simulations for tubes. The waves are believed to be kinetic based on a few evidences, including a well defined flux-density curve. In MD simulations of flows in hoppers, we find density waves, which are also believed to be kinetic.

The Emergence of Radiation from Gravitational Potential Wells: The Absence of $ωM$ Effects

description: We consider a source of gravitational waves of frequency $ω$, located near the center of a massive galaxy of mass $M$ and radius $R$, with $ω\gg R^{-1}$. In the case of a perfect fluid galaxy, and of odd-parity waves, there is no direct matter-wave interaction and the propagation of the waves is affected by the galaxy only through the curvature of the spacetime background through which the waves propagate. We find that, in addition to the expected redshift of the radiation emerging from the galaxy, there is a small amount of backscatter, of order $M/ω^2R^3$. We show that there is no suppression of radiative power by the factor $1+ω^2M^2/4$ as has been recently predicted by Kundu. The origin of Kundu's suppression lies in the interpretation of a term in the expansion of the exterior field of the galaxy in inverse powers of radius. It is shown why that term is not related to the source strength or to the strength of the emerging radiation.

description: We report the distribution of a cryptographic key, secure from photon number splitting attacks, over 35 km of optical fiber using single photons from an InAs quantum dot emitting ~1.3 microns in a pillar microcavity. Using below GaAs-bandgap optical excitation, we demonstrate suppression of multiphoton emission to 10% of the Poissonian level without detector dark count subtraction. The source is incorporated into a phase encoded interferometric scheme implementing the BB84 protocol for key distribution over standard telecommunication optical fiber. We show a transmission distance advantage over that possible with (length-optimized) uniform intensity weak coherent pulses at 1310 nm in the same system.

description: Körperliche, kulturelle, soziale und intellektuelle Freizeitaktivitäten – von der Teilnahme in einem Sportverein bis zum Lösen von Rätseln – spielen eine wichtige Rolle für das individuelle Wohlbefinden und die Lebensqualität. Sie stillen diverse Bedürfnisse, sind Verwirklichung von individuellen Präferenzen und Werten und helfen in der Regel auch dabei, soziale Kontakte zu pflegen, positive Emotionen zu verspüren, zu lernen und sich weiterzuentwickeln. Die Art der Freizeitaktivitäten, an denen Menschen teilnehmen, ist ein wesentlicher Faktor im Hinblick auf ihre Identität. Nur die berufliche Tätigkeit ist für die meisten Menschen von vergleichbarer Bedeutung, wobei diese im Alter an Relevanz verliert. Darüber hinaus zeigen Studien, dass körperliche, kulturelle, soziale und intellektuelle Freizeitbeschäftigungen langfristig positive Auswirkungen auf die Gesundheit haben, insbesondere auf die kognitive Leistungsfähigkeit. Dafür verantwortlich sind diverse psychologische, biologische und soziale Mechanismen wie zum Beispiel die Stärkung der Resilienz, Bewegungsförderung, Gesundheitsverhalten und der Aufbau von sozialem Kapital, um nur einige zu nennen. Im vorliegenden Themendossier sind wir der Frage nachgegangen, welche Freizeitaktivitäten heutige Seniorinnen und Senioren in jüngeren und mittleren Jahren ausgeübt haben und inwiefern sie diesen Aktivitäten im Pensionsalter weiterhin nachgehen. Zudem haben wir analysiert, inwiefern Freizeitaktivitäten in der ersten Lebenshälfte beziehungsweise aktuelle Freizeitaktivitäten und kognitive Leistungsfähigkeit im Pensionsalter zusammenhängen. Die Analyse der Daten des Schweizer Alterssurveys zeigt, dass Freizeitaktivitäten weit verbreitet sind und oft über das gesamte Leben hinweg Beständigkeit aufweisen. Insbesondere für körperliche, soziale und intellektuelle Aktivitäten zeigt sich diese Kontinuität. Des Weiteren zeigt sich, dass die kognitive Leistungsfähigkeit mit den Aktivitäten in der ersten Lebenshälfte und den aktuellen Freizeitaktivitäten in Zusammenhang steht. Personen, die in der ersten Lebenshälfte physisch, sozial oder intellektuell aktiv waren, wiesen eine bessere kognitive Leistungsfähigkeit auf als solche, die in dieser Hinsicht passiver waren. Dieses Muster stützt die These, dass körperliche, soziale und intellektuelle Aktivitäten dazu beitragen, die kognitive Leistungsfähigkeit im Alter zu stärken oder den Rückgang der kognitiven Leistungsfähigkeit hinauszuzögern.

description: We present mass estimates of supermassive black holes in six nearby fast rotating early-type galaxies (NGC4339, NGC4434, NGC4474, NGC4551, NGC4578 and NGC4762) with effective stellar velocity dispersion around 100 km/s. We use near-infrared laser-guide adaptive optics observations with the GEMINI/NIFS to derive stellar kinematics in the galactic nuclei, and SAURON observations from the ATLAS3D Survey for large-scale kinematics. We build axisymmetric Jeans anisotropic models and axisymmetric Schwarzschild dynamical models. Both modelling approaches recover consistent orbital anisotropies and black hole masses within 1-2sigma confidence level, except for one galaxy for which the difference is just above the 3sigma level. Two black holes (NGC4339 and NGC4434) are amongst the largest outliers from the current black hole mass - velocity dispersion relation, with masses of $(4.3^{+4.8}_{-2.3})\times10^7$ and $(7.0^{+2.0}_{-2.8})\times10^7$ M$_\odot$, respectively ($3σ$ confidence level). The black holes in NGC4578 and NGC4762 lie on the scaling relation with masses of $(1.9^{+0.6}_{-1.4})\times10^7$ and $(2.3^{+0.9}_{-0.6})\times10^7$ M$_\odot$, respectively (3sigma confidence level). For two galaxies (NGC4474 and NGC4551) we are able to place upper limits on their black holes masses ($<7\times10^6$ and $<5\times10^6$ M$_\odot$, respectively, $3σ$ confidence level). The kinematics for these galaxies clearly indicate central velocity dispersion drops within a radius of 35 pc and 80 pc, respectively. These drops cannot be associated with cold stellar structures and our data do not have the resolution to exclude black holes with masses an order of magnitude smaller than the predictions. Parametrizing the orbital distribution in spherical coordinates, the vicinity of the black holes is characterized by isotropic or mildly tangential anisotropy.

description: A series of novel ester derivatives 2 − 7, of natural product geodin 1, isolated from the soft coral-derived fungus Aspergillus sp., were designed and semi-synthesised through one step reaction with high yield. Compound 5 showed strong antifouling inhibitory activities with MIC of 4.80 μM while compound 4 showed selective inhibitory activities with MICs values 8.59 μM against Aeromonas salmonicida and Pseudomonas aeruginosa (Sea-Nine 211, MIC = 0.27 μM). Compounds 3, 4 and 6 showed potent anti-pathogenic inhibitory activities with MICs of 2.29 μM, 4.29 μM and 4.56 μM respectively against Staphylococcus aureus (Ciprofloxacin, MIC = 0.156 μM). Compound 2 showed weak inhibitory activity against A. salmonicida with MIC 18.75 μM (Sea-Nine 211, MIC = 0.27 μM) and with MICs 9.38 μM against S. aureus (ciprofloxacin, MIC = 0.156 μM). However, compound 7 showed very low antibacterial activities with MIC = >20 μM. The preliminary structure-activity relationships of compounds 2 − 7 further prove that the modification of 4-OH group of natural product geodin 1 improves the antibacterial activities such as antifouling and anti-pathogenic activities.

description: Background: Approximately 50% of survivors of childhood acute lymphoblastic leukemia (ALL) demonstrate cognitive impairments. However, the trajectory of change and contributing neuropathology is unclear, limiting our ability to tailor intervention content and timing. This study aimed to explore information processing abilities and brain morphology early post-treatment for pediatric ALL. Procedure: Twenty-one children at the end of ALL treatment and 18 controls underwent neuropsychological assessment. A subset also completed structural magnetic resonance imaging. Results: A principal component analysis generated two cognitive factors: information processing capacity and information processing speed. Compared to control group, the ALL group displayed deficits in capacity, but not speed. No group differences were identified in morphology. No relationship was identified between capacity or speed and morphology. Conclusion: Early cognitive intervention should target information processing abilities using a system-wide approach. Future studies should employ alternative imaging techniques sensitive to white-matter microstructure when exploring pathology underlying information processing deficits.
