We present a comprehensive study of the effects of third-order dispersion (TOD) on dispersion-managed (DM) solitons. The two main effects of TOD are creation of asymmetry of the DM soliton’s profile and generation of continuum radiation. Considering these two effects, we derive a conservative bound on the magnitude of TOD below which it will not have a significant detrimental effect on DM solit...

We report the detection of CN, HCN, HNC, CS, HCO+, C2H and H2CO (ortho and para) in the protoplanetary disks of DM Tau and GG Tau. For the first time organic molecules are observed in objects representative of the presolar nebula. These molecules are underabundant with respect to the standard dense clouds. The depletions in the “outer” disk of DM Tau (100 < r < 900 AU), derived from the line in...

It is well-known that if T is a Dm–Dn bimodule map on the m×n complex matrices, then T is a Schur multiplier and ‖T‖cb = ‖T‖. If n = 2 and T is merely assumed to be a right D2-module map, then we show that ‖T‖cb = ‖T‖. However, this property fails if m ≥ 2 and n ≥ 3. For m ≥ 2 and n = 3, 4 or n ≥ m2 we give examples of maps T attaining the supremum C(m,n) = sup{‖T‖cb : T a right Dn-module map o...

Emission from the 212 − 111 line of H2CO has been detected and marginally resolved toward LkCa15 by the Nobeyama Millimeter Array. The column density of H2CO is higher than that observed in DM Tau and than predicted by theoretical models of disk chemistry, and the line intensity profile is less centrally peaked than that for CO. Similar behavior is observed in other organic gaseous molecules in...

It is known that cardiovascular complications plays important roles in the development of diabetes mellitus (DM) and platelet dysfunction is one of the key reasons which led to microangiopathy. This study was designed to investigate the mitochondria function changes of platelet in DM rats and DM patients. The results showed that the platelets viability, platelet adenosine triphosphate (ATP) con...

In a practical project a statistical analysis of the Web log files of the domain www.volkswagen.de was carried out by using the CRISP-DM procedure. For the preprocessing phase, more profound findings could be gained than are usually described in many studies. Since the aim was to deduce significant statements while measuring the effect, tests of significance for e-metrics were used in addition ...

The velocity function derived from large scale surveys can be compared with the predictions of ΛCDM cosmology, by matching the measured rotation velocities Vrot of galaxies to the maximum circular velocity of dark matter (DM) halos Vmax. For Vrot<50 kms−1, a major discrepancy arises between the observed and ΛCDM velocity functions. However, the manner in which different observational measures o...

In a recent publication [10] the author showed that self-motions of general planar Stewart Gough platforms can be classified into two so-called Darboux Mannheim (DM) types (I and II). Moreover, in [10] the author was able to compute the set of equations yielding a type II DM selfmotion explicitly. Based on these equations we present a basic result for this class of self-motions.
