The familial placements of Cyrtandromoea Zoll. and Wightia Wall., two small and enigmatic South‐East Asian genera, have long been controversial in Lamiales. Here we adopt a two‐step approach to resolve their phylogenetic relationships. We initially reconstructed a large‐scale phylogeny of Lamiales using six chloroplast markers (atpB, matK, ndhF, psbBTNH, rbcL, and rps4). The results showed that both Cyrtandromoea and Wightia emerged in the LMPO clade, including Lamiaceae, Mazaceae, Phrymaceae, Paulowniaceae, and Orobanchaceae. Based on the second set of six chloroplast markers (atpB, matK, ndhF, rbcL, rps16, and trnL‐F) and two nuclear ribosomal regions (external transcribed spacer and internal transcribed spacer) for the analyses focusing on the LMPO clade, our results revealed that Cyrtandromoea was consistently nested within Phrymaceae, whereas Wightia was supported as sister to Phrymaceae by the chloroplast DNA dataset or sister to Paulowniaceae by the nuclear ribosomal DNA dataset. Morphological and anatomical evidence fully supports the inclusion of Cyrtandromoea in Phrymaceae, and an updated tribal classification is done for Phrymaceae with five tribes, that is, Cyrtandromoeeae Bo Li, Bing Liu, Su Liu & Y. H. Tan, trib. nov., Diplaceae Bo Li, Bing Liu, Su Liu & Y. H. Tan, trib. nov., Leucocarpeae, Mimuleae, and Phrymeae. The conflicting phylogenetic position of Wightia indicated by different genome markers results in difficulty placing the genus in either Phrymaceae or Paulowniaceae. Considering the distinct morphological differences between Wightia and other families in the LMPO clade, we here propose a new family, Wightiaceae Bo Li, Bing Liu, Su Liu & Y. H. Tan, fam. nov., to accommodate it, which is the 26th family recognized in Lamiales.

It is shown that relaxions can be formed in a solid at temperature T ≧ TSCHA. (= TEB). Lattice theory of polymer solutions is applied to a solid having two types of atoms — localized atoms and relaxion atoms. The relaxion instability temperature is found to be smaller than TEB. The relaxion model and energy balance criterion together lead to the conclusion that at TEB the solid transforms into a relaxion liquid, i.e., Tm = TEB. The model is (i) in agreement with the Lindemann equation of melting, (ii) explains qualitatively the increase in entropy at melting, and (iii) shows why a solid cannot be superheated above TEB (= Tm), but the liquid can be supercooled to TR (< Tm). Es wird gezeigt, das sich im Festkorper bei Temperaturen T = TSCHA (= TEB) Relaxionen aus-bilden. Die Gittertheorie von Polymerlosungen wird auf einen Festkorper mit zwei Atomarten — lokalisierte Atome und Relaxionsatome — angewendet. Es wird gefunden, das die Relaxions-instabilitatstemperature kleiner als TEB ist. Das Relaxionsmodell zusammen mit dem Energie-bilanzkriterium fuhrt zu dem Schlus, das bei TEB der Festkorper in eine Relaxionsflussigkeit ubergeht, d. h. Tm = TEB. Das Modell ist 1. in Ubereinstimmung mit der Schmelzgleichung von Lindemann, 2. erklart es qualitativ den Entropieanstieg beim Schmelzen und 3. zeigt es, warum ein Festkorper nicht uber TEB (= Tm) aufgeheizt, jedoch die Flussigkeit auf TR (< Tm) unter-kuhlt werden kann.

The energy balance criterion of melting of solids is formulated. According to this criterion, the solid becomes unstable when Evib = ƒEp, that is, when the vibrational energy Evib is a fraction ƒ (≦ 1) times the total energy of interaction of the vibrating atoms Ep. For an isotropic Debye solid, the relationship between Evib and Ep is derived using the self-consistent harmonic approximation (SCHA) model. The present study complements the results of the SCHA model and gives the relationship between Ep and Tm. The interaction energy calculations for the rare gas solids yield ƒ ≈ 0.32 to 0.43, which is consistent with the value ƒ ⪅ 1 expected on the basis of the cohesive energy arguments. Es wird das Energiebilanzkriterium des Schmelzens von Festkorpern formuliert. Entsprechend diesem Kriterium wird der Festkorper instabil, wenn Evib = ƒEp, d. h. wenn die Schwingungsenergie Evib ein Bruchteil ƒ (⪅ 1) der Gesamtwechselwirkungsenergie der Schwingungsatome, Ep ist. Fur einen isotropen Debye-Festkorper wird die Beziehung zwischen Evib und Ep mit der selbstkonsistenten harmonischen Naherung (SCHA) abgeleitet. Die Untersuchung vervollstandigt die Ergebnisse des SCHA-Modells und ergibt die Beziehung zwischen Ep und Tm. Die Berechnungen der Wechselwirkungsenergie fur Seltenerd-Festkorper liefert ƒ ≈ 0,32 bis 0,43, was mit dem Wert ƒ ⪅ 1, der auf der Grundlage von Kohasionsenergiebetrachtungen erwartet wird, konsistent ist.

The electrocardiograms of 1,171 patients above the age of 65 in a predominantly geriatric institution were reviewed to determine the incidence of tachyarrhythmias. Data on the overall incidence and the individual types of arrhythmias are presented. Atrial fibrillation was the most common arrhythmia observed, followed by atrial flutter and supraventricular tachycardia. Atrial fibrillation often was associated with other evidence of myocardial damage. The significance of sinus bradycardia and grade I A-V block in the pathogenesis of atrial fibrillation and the significance of the tachyarrhythmias are discussed.
