The anion is composed of two SnE4 tetrahedra sharing a common edge with C2h symmetry. All the lanthanide(III) atoms are eight‐coordinate by six nitrogen atoms of three en ligands and two oxygen atoms of two μ2‐OH groups forming distorted bicapped trigonal prisms. In compounds 1‐3, extensive hydrogen bonds are formed leading to three‐dimensional networks of anions and cations. Compounds 1‐3 remove all the organic part in one step upon heating in the nitrogen stream.

The Network Structure [SbHg2]GaCl4: An X‐Ray Study of a Temperature Driven Phase Transition
Authors: Schlirf J. , Deiseroth H. J.
Published: June 2007

[SbHg2]GaCl4 is a new compound forming red, transparent, air sensitive crystals with a cationic network [SbHg2]+ topologically related to cristobalite. Tetrahedral (GaCl4)− groups are located in suitable cavities. The title compound is the first example of this formula type with antimony and exists in a low (LT) and a high‐temperature (HT) modification (Tc = 277 K). The HT‐modification crystallizes in space group Pbcn (no. 60) with the lattice constants a = 1200.23(4) pm, b = 876.15(4) pm, c = 1750.83(6) pm (Z = 8, T = 293 K) whereas the LT‐modification crystallizes in Pna21 (no. 33) with a = 1743.30(6) pm, b = 874.36(5) pm, c = 1196.92(4) pm (T = 170 K). The phase transition is partially of first order and is investigated by a series of temperature dependent X‐ray single crystal measurements. The origin of the phase transition is most likely a significant librational disorder of the GaCl4 tetrahedra at higher temperatures which is frozen out in the LT‐modification. This becomes obvious from only one type of GaCl4 tetrahedra with unusual large anisotropic thermal parameters for the Cl atoms in the HT‐modification. In the LT‐modification two types of GaCl4 groups with significantly reduced thermal parameters and slightly different orientations are found. A comparison of the interatomic distances between the Cl atoms of the GaCl4 groups and atoms in the first coordination sphere gives evidence that in one orientation the interaction between Cl and Sb and in the other the interaction between Cl and Hg is optimized.

Authors: Fu Wenyi , Edelmann Frank , Takats Josef
Published: June 2007

Deprotonation of the readily available organometallic aldehyde derivative [(η4‐C7H7CHO)Fe(CO)3] (2) with NaN(SiMe3)2 in benzene solution at ambient temperature afforded the anionic formylcycloheptatrienyl complex Na[(η3‐C7H6CHO)Fe(CO)3] (3). The anion is fluxional in solution and displays a unique ambident reactivity towards electrophiles (MeI, Me3SiCl). New substituted [(η4‐RC7H6CHO)Fe(CO)3] and [(η4‐heptafulvene)Fe(CO)3] complexes have been identified as the products. Treatment of 3 with 0.5 equivalents of dimeric [(COD)RhCl]2 (COD = 1,5‐cyclooctadiene) afforded the functionalized Fe‐Rh cycloheptatrienyl complex [(μ‐C7H6CHO)(CO)3FeRh(COD)] (7) in up to 86 % yield. Carbonylation of 7 under an atmosphere of CO led to facile conversion to the heterobimetallic pentacarbonyl derivative [(μ‐C7H6CHO)(CO)3FeRh(CO)2] (8), which is also accessible in lower yield from the direct reaction of 3 with [Rh(CO)2Cl]2.

Syntheses and Properties of Di‐tert‐butylphosphides [M(PtBu2)2]2 (M = Zn, Hg) and [Cu(PtBu2)]4

The phosphides [M(PtBu2)2]2 (M = Zn, Hg) and [Cu(PtBu2)]4 are accessible from reaction of LiPtBu2 with ZnI2, HgCl2 and CuCl, respectively. [M(PtBu2)2]2 (M = Zn, Hg) are dimers in the solid state. X‐ray structural analyses of these phosphides reveal that [M(PtBu2)2]2 (M = Zn, Hg) contain four‐membered M2P2‐rings whereas [Cu(PtBu2)]4 features a planar eight‐membered Cu4P4‐ring. Degradation reaction of LiPtBu2(BH3) in the presence of HgCl2 results in the dimeric phosphanylborane BH3 adduct [tBu2PBH2(BH3)]2. X‐ray quality crystals of [tBu2PBH2(BH3)]2 (monoclinic, P21/n) are obtained from a pentane solution at 6 °C. According to the result of the X‐ray structural analysis, the O2‐oxidation product of [Hg(PtBu2)2]2, [Hg{OP(O)(tBu)OPtBu2}(μ‐OPtBu)]2, features in the solid state structure two five‐membered HgP2O2‐rings and a six‐membered Hg2P2O2‐ring. Herein the spiro‐connected Hg atoms are member of one five‐membered and of the six‐membered ring.

La3OCl[AsO3]2: A Lanthanum Oxide Chloride Oxoarsenate(III) with a “Lone‐Pair” Channel Structure

La3OCl[AsO3]2 was prepared by the solid‐state reaction between La2O3 and As2O3 using LaCl3 and CsCl as fluxing agents in evacuated silica ampoules at 850 °C. The colourless crystals with pillar‐shaped habit crystallize tetragonally (a = 1299.96(9), c = 558.37(5) pm, c/a = 0.430) in the space group P42/mnm (no. 136) with four formula units per unit cell. The crystal structure contains two crystallographically different La3+ cations. (La1)3+ is coordinated by six oxygen atoms and two chloride anions in the shape of a bicapped trigonal prism (CN = 8), whereas (La2)3+ carries eight oxygen atoms and one Cl− anion arranged in the shape of tricapped trigonal prism (CN = 9). The isolated pyramidal [AsO3]3− anions (d(As–O) = 175–179 pm) consist of three oxygen atoms (O2 and two O3), which surround the As3+ cations together with the free, non‐binding electron pair (lone pair) Ψ1‐tetrahedrally (∢(O–As–O) = 95°, 3×). One of the three crystallographically independent oxygen atoms (O1), however, is exclusively coordinated by four (La2)3+ cations in the shape of a real tetrahedron (d(O–La) = 236 pm, 4×). These [(O1)(La2)4]10+ tetrahedra form endless $\rm ^{1}_{\infty}\{[OLa^{e}_{4/2}]^{4+}\}$ chains in the direction of the c axis through trans‐edge condensation. Empty channels, constituted by the lone‐pair electrons of the Cl− anions and the As3+ cations in the Ψ1‐tetrahedral oxoarsenate(III) anions [AsO3]3−, run parallel to [001] as well.

Authors: Kótai László , Sajó István E. , Gács István , Sharma Pradeep K. , Banerji Kalyan K.
Published: June 2007

Two convenient methods were developed to transform KMnO4 into barium permanganate and other permanganate salts via BaMnO4 or Mn2O7 intermediates. Pure BaMnO4 was prepared by the reaction of KMnO4 with KI in the presence of BaCl2 and NaOH. Hydrothermal reaction of barium manganate with excess carbon dioxide for 1.5 h at 100 °C led to barium‐permanganate with almost quantitative yield. Mn2O7 was prepared by means of the reaction of KMnO4 and sulfuric acid monohydrate in a two‐phase (CCl4‐H2SO4.H2O) system. In the presence of excess barium carbonate and catalytic amount of water barium permanganate could be obtained with a moderate yield. Similarly, other permanganate salts (Zn, Cd, Cu, Mg, Ca, Ni, Al, Fe, Ce, rare earth metals) were prepared by substituting the BaCO3 for the appropriate metal oxides, hydroxides or carbonates.

(Me2NH2)[(Ph3Sn)3(MoO4)2], a Triorganotin Molybdate with Layer Structure

The reaction of [(Ph3Sn)2MoO4] with (Me2NH2)Cl in an acetonitrile/water mixture leads to the formation of (Me2NH2)[(Ph3Sn)3(MoO4)2] (1). (1) crystallizes in the space group Pca21 with a = 1967.0(4), b = 1353.1(2) and c = 2176.6(5) pm. In the crystal structure of 1 Ph3SnO2 bipyramides and MoO4 tetrahedra are linked by corner sharing to give a layer structure. Additionally the layers are connected by O···H···N hydrogen bridges between MoO4 groups and [Me2NH2]+ ions to give a 3D network structure.

Authors: Vocke W.
Published: June 2007

Der profil‐ebene Spannungszustand [1] führt im allgemeinen Fall auf eine Differentialgleichung der Spannungsfunktion F, die wesentlich umfangreicher ist als die Bipotentialgleichung der Ebene. Beim Keilprofil läßt sich jedoch in Sonderfällen eine vom Verfasser eingeführte verkürzte Gleichung anwenden, die fast der Bipotentialgleichung entspricht und geschlossene Lösungen zuläßt.

Trigonometric Interpolation and Predictor‐Corrector Formulas for Numerical Integration
Authors: Salzer Herbert E.
Published: June 2007

Formulas are derived for n1/2‐point osculatory trigonometric interpolation, which give the unique trigonometric sum Sn(x) satisfying Sn(xi) = f(xi), i = 1,2, …, n, and S′n(xi) = f′(xi), i = 1,2, …, n + 1. In conjunction with previously derived formulas, we have predictor‐corrector formulas for stepwise numerical integration of y′ = Φ(x, y). These formulas might be applicable to numerical integration where y is either purely or nearly periodic (e. g., orbits, satellites, etc.). For each n, for xi equally spaced at intervals of h, there is a different predictor‐corrector pair for every h. To obtain predictor‐corrector formulas for y″ = Φ (x, y, y′), one requires n 1/3 ‐and n 2/3 ‐point hyperosculatory trigonometric interpolation formulas (i. e., based upon fi, f′i and f′i, i = 1,2, …, n, and one or two out of fn+1, f′n+1, and f″n+1). A procedure is outlined for obtaining unique n 1/3 ‐and n 2/3 ‐point formulas (different for odd and even n). Remainder formulas in terms of divided differences for complex arguments (not too informative) are given for some formulas having an odd number of interpolation conditions.

Ausbreitung von punktförmig erregten Wellen in einem gleichförmig bewegten Medium
Authors: Becker Ernst
Published: June 2007

Ein unbegrenztes, schwingungsfähiges Medium wird durch eine raumfeste, punktförmige, harmonisch pulsierende Störung zu Wellen angeregt, die vom Störzentrum fortlaufen. Die Flächen konstanter Phase (z. B. die Flächen, auf denen zu einem bestimmten Zeitpunkt die Wellenberge liegen) für ruhendes und für gleichförmig bewegtes Medium werden miteinander verglichen. Unter gewissen Umständen gehen diese Flächen durch eine einfache Verschiebung in Bewegungsrichtung des Mediums auseinander hervor. Notwendige und hinreichende Bedingung hierfür ist die Unabhängigkeit des Vektors der Gruppengeschwindigkeit vom Betrag des Wellenzahlvektors. Die Überlegungen gestatten auch einige Folgerungen für die Deformation der Phasenflächen in den Fällen, in denen diese Bedingung nicht erfüllt ist.
Die Bewegung eines einfachen Wagenmodells
Authors: Bottema O.
Published: June 2007

Es wird die Bewegung eines ebenen mechanischen Systems mit vier Freiheitsgraden betrachtet, das sich kräftefrei auf einer waagerechten Ebene bewegt. Das System besteht aus zwei gelenkig verbundenen starren Körpern L1 und L2, denen man je eine nicht‐holonome Bedingung auferlegt. Kinematische Überlegungen zeigen, daß zwei Hauptfälle zu unterscheiden sind: die Bahn des Mittelpunkts Q der „Hinterachse”︁ hat entweder unendlich viele Rückkehrpunkte und Wendepunkte oder eine Rückkehrpunkt und keine Wendepunkte. Die Bewegungsgleichungen kann man immer elementar soweit integrieren, daß die Abhängigkeit zwischen den Drehwinkeln der Körper und der Zeit bekannt ist. In einem Spezialfall gelingt es auch, die Bahnkurve von Q zu bestimmen, die sich als eine Kreistraktrix erweist.
Gestaltaussagen über dissoziierte und andere chemisch reagierende Zweistoffgrenzschichten
Authors: Adams Ernst
Published: June 2007

Allgemein gültige Aussagen über chemisch reagierende, kompressible, laminare, instationäre Grenzschichten mit zwei Komponenten werden mit Hilfe des Nirenbergschen Maximumprinzips hergeleitet. Die thermodynamischen und Transporteigenschaften, die Verteilungen des Druckes, des Massen‐ und des Wärmeübergangs sind beliebig. Die folgenden Ergebnisse gelten z. B. für dissoziierte Luft als Lighthill‐Gas oder für die Injektion eines Fremdgases: 1. Schranken für die Massenkonzentrationen werden angegeben, und zwar für den Fall des thermodynamischen Gleichgewichtes, für eingefrorene Reaktionen und für einen Typus von Staupunktströmungen außerhalb des Gleichgewichtes February Die Ablösung wird allein durch den Druckgradienten bestimmt. 3. Wenn die Schallgeschwindigkeit am Außenrand der Grenzschicht gegen Null geht, kann die Geschwindigkeitskomponente u im Inneren der Grenzschicht kein Extremum annehmen.
Zur Stabilitätsprüfung mittels der Frequenzgänge von Regler und Regelstrecke
Authors: Kaerkes R.
Published: June 2007

Von H. Cremer und F. Kolberg wurde 1960 ein Kriterium zur Prüfung des Stabilitätsverhaltens eines geschlossenen Regelkreises anhand der Ortskurven von Regler und Regelstrecke angegeben, das auf der Untersuchung der Ortskurven in Umgebungen von Punkten gleichen Argumentes beruht. In der vorliegenden Arbeit werden gleichwertige Kriterien abgeleitet ausgehend von den Kroneckerschen Indizes gewisser Schnitt‐stellen der beiden Ortskurven.

Über Operatorgleichungen mit nicht linear auftretendem Parameter
Authors: Hadeler K. P.
Published: June 2007

Es werden Eigenwertaufgaben vollstetiger Operatoren behandelt, in denen der Parameter in der ersten und zweiten Potenz auftritt. Unter gewissen Voraussetzungen sind diese Aufgaben äquivalent zu selbstadjungierten Aufgaben mit linear auftretendem Parameter, so daß sich die für solche Aufgaben bekannten Einschließungssätze und Iterationsmethoden übertragen lassen. Eigenwertaufgaben von Differentialgleichungen mit linearer und quadratischer Abhängigkeit vom Parameter lassen sich in vielen Fällen auf Aufgaben vollstetiger Operatoren des genannten. Typs zurückführen. In einem zweiten Abschnitt werden Eigenwertaufgaben betrachtet, die von einem Parameter in monotoner Weise abhängen. Es werden Schranken für den Wert des Parameters berechnet, für den der kleinste bzw. größte Eigenwert gleich eins ist.
Optimale Anfangsverteilungen bei der Monte‐Carlo‐Methode mit Informationsspeicherung
Authors: Amann H.
Published: June 2007

Die Monte‐Carlo‐Methode mit Informationsspeicherung zur Lösung elliptischer Randwertprobleme macht von der Markoffeigenschaft der Irrwanderung eines Teilchens in einem Gittergebiet Gebrauch. Danach kann jeder Punkt, der bei der Irrfahrt mindestens einmal berührt wird, als Ausgangspunkt eines neuen Irrweges angesehen werden, und man erhält so bei der Simulation einer einzigen Irrfahrt Näherungswerte für die Lösung in mehreren Gitterpunkten zugleich. Bei dieser Betrachtungsweise erhebt sich die Frage, wo das Teilchen seine Irrfahrt nun wirklich beginnen soll, d. h. die Frage nach der Wahl der Anfangsverteilung. Bei Zugrundelegung verschiedener Gütekriterien wird dieses Problem eingehend diskutiert, was zu nützlichen Folgerungen für die praktische Rechnung führt. Einige numerische Beispiele veranschaulichen die erhaltenen Ergebnisse.
Beitrag zur Kerbspannungstheorie
Authors: Landgraf G. , Löbel G.
Published: June 2007

Eine hinreichend genaue Berechnung des Kerbfaktors ist oft nur durch Interpolieren zwischen den Lösungen für die flache und die tiefe Kerbe möglich. Bei Kerben mit parallelen Flanken und kreisförmigen Grund gelingt mittels einer neuen Abbildungsfunktion von G. Landgraf eine strenge Lösung des Problems mit der Hablkreiskerbe als Grenzfall für die flache und der Schlitzkerbe als Grenzfall für die tiefe Kerbe. Die Lösungen enthalten elliptische Integrale 1. und 2. Gattung. Bei der Auswertung wurde daher ein graphisches Verfahren benutzt, um mit möglichst geringem Aufwand die Kerbfaktoren für eine Vielzahl von Fällen ermitteln zu können.
Green's Functions in the Non‐Stationary Theory of Elastic Shells
Authors: De Silva C. N. , Whitman A. B.
Published: June 2007

The method of Green's function is extended to the thermoelastic Kirchhoff‐Love theory of thin shells. A reciprocity theorem and heat conduction equations appropriate to the Kirchhoff‐Love theory are used to derive integral solution formulas for middle surface displacements involving six Green's functions. The equations determining the Green's functions are deduced and compared to those for shallow shells. Both sets of equations are solved by conventional techniques for an infinite circular cylindrical shell. One of the Green's functions is evaluated numerically at the source point for both theories, and a comparison between them is made for various ratios of shell thickness to radius.
Drei‐Front‐Konfigurationen mit Energiezufuhr
Authors: Rues D.
Published: June 2007

Es werden die verschiedenen Möglichkeiten der Energiezufuhr auf Diskontinuitätsflächen in einer Überschallparallelströmung betrachtet. Dabei zeigt sich, daß die Energiezufuhr auf einer Front unter gleichzeitiger Ausbildung nur einer Stoßwelle nicht möglich ist, sondern daß sich zusätzlich zu der Energiefront noch mindestens zwei Stoßfronten ausbilden müssen. Für eine Anströmmachzahl M∞ = 10 und eine Energiezufuhr qi/W = 0,1 werden die verschiedenen möglichen Frontwinkel sowie die Drücke und die Stromlinienwinkel hinter den Fronten berechnet. Für einige Bereiche ergeben sich dabei mehrere Lösungen, während für andere, wozu natürlich auch der Choking‐Bereich gehört, keine stationären Lösungen existieren.
Ein einfaches Modell zur Berechnung von Vertikalschwingungen im inhomogenen linear elastischen Halbraum
Authors: Schimmerl J.
Published: June 2007

Ein elastisch isotroper inhomogener Halbraum soll durch ein einachsig zylindersymmetrisches Modell so ersetzt werden, daß er bei Schwingungen ein möglichst analoges Verhalten zeigt. Dies wird so erreicht, daß für den gegebenen veränderlichen Elastizitätsmodul E(z) die zugehörige Querschnittsfläche F(z) gesucht wird, die das dispersionsfreie Modell charakterisiert. Neben der Berechnung der Spannung σ, der Verschiebung w und der Amplitude W bei Schwingungen eines Fundaments auf dem inhomogenen Halbraum wird die Möglichkeit der Bestimmung von Bodenkennziffern aus charakteristischen Meßkurven angedeutet.
Selective COX‐2 Inhibitors, Eicosanoid Synthesis and Clinical Outcomes: A Case Study of System Failure
Authors: James M. J. , Cook‐Johnson R. J. , Cleland L. G.
Published: June 2007

Elucidation of differences between the active sites of COX‐1 and COX‐2 allowed the targeted design of the selective COX‐2 inhibitors known as coxibs. They were marketed as non‐steroidal anti‐inflammatory drugs (NSAIDs) that had improved upper gastrointestinal (GI) safety compared with older non‐selective NSAIDs such as diclofenac and naproxen. Two GI safety studies conducted with arthritis patients demonstrated that in terms of upper GI safety, celecoxib was not superior to diclofenac (CLASS study) but rofecoxib was superior to naproxen (VIGOR study). However, the VIGOR study revealed also that rofecoxib had increased cardiovascular (CV) risk compared with naproxen. This clinical outcome was supported by the existence of plausible eicosanoid‐based biological mechanisms whereby selective COX‐2 inhibition could increase CV risk. Nevertheless, the existence of CV risk with rofecoxib was successfully discounted by its pharmaceutical company owner, Merck & Co, with the assistance of specialist opinion leaders and rofecoxib achieved widespread clinical use for 4–5 years. Rofecoxib was withdrawn from the market when several clinical trials in colorectal cancer and post‐operative pain revealed increased CV risk with not only rofecoxib, but also coxibs. The commercial success of rofecoxib provides a case‐study of failure of the medical journal literature to guide drug usage. Attention to ethical issues may have provided a more useful guide for prescribers.
Production of 14‐Oxo‐cis‐11‐eicosenoic Acid from Lesquerolic Acid by Sphingobacterium multivorum NRRL B‐23212
Authors: Kuo Tsung Min , Isbell Terry A. , Rooney Alejandro , Levinson William E. , Frykman Hans
Published: June 2007

The objective of this study was to explore the extent of microbial conversion of lesquerolic acid (14‐hydroxy‐cis‐11‐eicosenoic acid; LQA) by whole cell catalysis and to identify the newly converted products. Among compost isolates including NRRL strains B‐23212 (Sphingobacterium multivorum), B‐23213 (Acinetobacter sp.), B‐23257 (Enterobacter cloacae B), B‐23259 (Escherichia sp.) and B‐23260 (Pseudomonas aeruginosa) the S.multivorum strain was the only microorganism that converted LQA to produce a new product identified as 14‐oxo‐cis‐11‐eicosenoic acid by GC‐MS and NMR analyses. The conversion yield was 47.4% in 48 h at 200 rpm and 28°C in small shake flask experiments. In comparison, both Acinetobacter and Pseudomonas strains failed to convert LQA to major new products but used LQA apparently as an energy source during fermentation. For structural analysis, 6.88 g of 14‐oxo‐cis‐11‐eicosenoic acid was produced from converting 11 g LQA (a 62% yield) in 72 h at 200 rpm and 28 °C in Fernbach flasks using 18‐h‐old NRRL B‐23212 cultures and an improved medium that also contained EDTA and glycerol in lieu of glucose as carbon source. NRRL B‐23212 was further identified by 16S rRNA gene sequence analysis as a unique strain of S. multivorum. Therefore, S. multivorum NRRL B‐23212 possesses an enzymatic activity presumably a secondary alcohol dehydrogenase for converting LQA to produce 14‐oxo‐cis‐11‐eicosenoic acid, a first report that demonstrates the functional modification of LQA by whole cell catalysis.
Excision of the tricuspid valve in a baby with Candida endocarditis
Authors: du Plessis Frederik A. , Helbing Willem A. , Bogers Ad J.J.C.
Published: June 2007

We report on the management of Candida endocarditis in a 5-month old infant. The orifice of the tricuspid valve was totally obstructed, and the tension apparatus of the valve destroyed. Excision of the valve led to severe failure of the right heart. The combined use of anti-failure treatment, and reduction of right ventricular afterload with oxygen, nitric oxide and sildenafil, proved successful.
Movement along a low‐angle normal fault: The S reflector west of Spain
Authors: Reston T. J. , Leythaeuser T. , Booth‐Rea G. , Sawyer D. , Klaeschen D. , Long C.
Published: June 2007

The existence of normal faults that moved at low angles (less than 20°) has long been debated. One possible low‐angle fault is the S detachment at the west Galicia (Spain) margin and thought to occur at the top of serpentinized mantle. It is unlikely that S was a large submarine slide as it was probably active over several million years without the development of any compressional features such as toe thrusts, it appears to have rooted beneath the conjugate Flemish Cap margin, and it is similar to structures elsewhere that also appear to be rooted detachments. Here we analyze depth images to identify synrift sediment packages above S and use the geometry of these synrift packages to constrain the angle at which S both formed and remained active. We find that S must have remained active at angles below 15°, too low to be explained simply by the low friction coefficient of partially serpentinized peridotites. Instead, we suggest that transient high fluid pressures must have developed within the serpentinites and propose a model in which anastomosing fault strands are alternately active and sealed, enabling moderately high fluid pressures to develop.
Evolution of mixing state of black carbon particles: Aircraft measurements over the western Pacific in March 2004

Published: June 2007

We report the evolution of the mixing state of black carbon (BC) particles in urban plumes measured by an airborne single particle soot photometer. The aircraft observations were conducted over the ocean near the coast of Japan in March 2004. The number fraction of coated BC particles with a core diameter of 180 nm increased from 0.35 to 0.63 within 12 hours (h), namely 2.3% h−1, after being emitted from the Nagoya urban area in Japan. BC particles with a core diameter of 250 nm increased at the slower rate of 1.0% h−1. The increase in coated BC particles was associated with increases in non‐sea salt sulfate and water‐soluble organic carbon by a factor of approximately two, indicating that these compounds contributed to the coating on the BC particles. These results give direct evidence that BC particles become internally mixed on a time scale of 12 h in urban plumes.
Multi‐input data derived Dst model
Authors: Zhu D. , Billings S. A. , Balikhin M. A. , Wing S. , Alleyne H.
Published: June 2007

A multi‐input single‐output (MISO) discrete time model is identified for the Dst dynamics using the Nonlinear Autoregressive Moving Average Model with Exogenous Input (NARMAX) approach to describe the dynamics of the geomagnetic index Dst under the influence of two solar wind parameters V Bs and the dynamical pressure P. The identified model provides a concise representation for the evolution of the Dst index and is able to forecast the dynamics of Dst more accurately in comparison with previously derived single‐input NARMAX models.
