The determinants of net interest margins & net interest spreads in the Russian & Japanese Commercial Banking sectors

This study presents an empirical investigation of the determinants of net interest margins and spreads in the Russian and Japanese banking sectors with a particular focus on commercial banks. Net interest mar-gins and spreads serve as indicators of financial intermediation efficiency. This paper employed a bank-level unbalanced panel dataset prolonging from 2005 to 2014. My main empirical results show that bank characteristics explain the most of the variation in not only net interest margins but also in spreads. Capi-talization, liquidity risk, inflation, economic growth, private and government debt are important determi-nants of margin in Russia. In Japan to the contrary loan and deposit market concentration along with bank size do predominate. Common significant variables in both countries are the substitution effect, cost effi-ciency and profitability. Turning to net interest spreads, micro- and macro-specific variables are the main significant drivers in Russia. I reach the conclusion that there are no significant determinants of net interest spreads in Japan within the original selection of variables, but operating efficiency and deposits to total funding seem to prevail. In both countries, there are solid differences in the net interest margins as well as spreads once the pre- and the post-crisis periods are considered

Meḥemmed Kemālī und seine Abhandlung über die osmanische Rechen- und Buchhaltungskunst aus dem Jahr 1587

Diese Arbeit beruht auf der Transkription und Übersetzung der Abhandlung des Meḥemmed Kemālī, eines osmanischen Finanzbeamten des 16. Jh.s in Buda, über die osmanische „Rechen- und Buchhaltungskunst“. Inhaltlich kann die Abhandlung in drei Hauptteile gegliedert werden. Im ersten Teil, dem Teil der „Buchhaltungsskunst“, erklärt uns Kemālī zuerst die Bedeutung von Abkürzungszeichen in der Buchhaltung und veranschaulicht dies am Beispiel eines (Registerheft-)Eintrags zur Vergabe eines gedüks, einer Stelle. Dann werden die Feinheiten der Soldauszahlung erläutert. Im zweiten Teil, dem Teil der „Rechenkunst“ werden nützliche Hinweise zur Multiplikation und Division sowie deren Proben gegeben und anhand von Beispielen ausgeführt. Weiters erklärt uns Kemālī mithilfe einer anteilsmäßigen Schulden-rückzahlung die Dreisatzregel mit direkter Proportionalität. Den dritten Teil der Abhandlung bilden Tabellen zu den im ersten Teil erwähnten Soldberechnungen. Zusätzlich wird ein außerthematischer Einschub, ein Gedicht von 4 Versen, das auf Sinān Paşa, dem Beglerbegi von Buda gedichtet wurde, vorgestellt. Die Arbeit selbst wird mit Informationen zum Leben und Werk des Autors, der unter dem Dichternamen Defterdār-zāde bzw. Balāṭī-zāde Meḥemmed Kemālī bekannt war, eingeleitet. Nach Transkription und Übersetzung der Abhandlung folgt für das bessere Verständnis ein Kommentar, das neben einer ausführlichen Inhaltsangabe auch Erläuterungen und Ausführungen zu den in der Abhandlung vorkommenden Begriffen und Namen beinhaltet. Weiters wird im Kommentar die Arithmetik des Kemālī mit Beispielen aus dem Rechenbuch des deutschen Rechenmeisters Adam Ries (m. 1559) vergliechen

FT-IR Spectroscopic Study of the Hofmann-Td-type Clathrates: Ni(1,9-diaminononane)M\u27(CN)4 ⋅2G (M\u27 = Cd or Hg, G = Benzene, 1,2-Dichlorobenzene or 1,4-Dichlorobenzene)

New Hofmann Td-type clathrates in the form of Ni(1,9-diaminononane)M\u27(CN)4 ⋅ 2G (M\u27 = Cd or Hg, G = benzene, 1,2-dichlorobenzene or 1,4-dichlorobenzene) were prepared in powder form and their infrared spectra are reported in the range of 4000–200 cm–1. As seen from the spectral features, the present compounds are similar in structure to the Hofmann Td-type clathrates

Effect of Helicobacter pylori infection on deep vein thrombosis seen in patients with Behçet's disease

Objective: To investigate the role of homocysteine metabolism due to Helicobacter pylori infection on the development of deep vein thrombosis (DVT) in patients with Behcet's disease (BD). Design: Prospective clinical study. Setting: Teaching hospital. Subject: Fifty-five patients with BD divided into groups, with DVT and without DVT, 19 healthy individuals and 18 patients with coronary artery disease (CAD) were enrolled into the study. Interventions: Plasma homocysteine and Hp seropositivity were determined. Results: There was significant Hp positivity in all groups (p>0.05). Homocysteine levels were not significantly different for each group except patients with CAD (p>0.05). Conclusion: There was no difference for frequency of Hp infection in all groups. We conclude that Hp does not influence DVT seen in BD via homocysteine metabolism, but the methinnin-loading test would be appropriate for enlighting patients whose fasting plasma homocysteine levels are found to be normal.

Reaction time and brake pedal force after total knee replacement: timeframe for return to car driving

Purpose: This prospective cohort study aimed to examine objective and subjective parameters in patients who underwent total knee replacement (TKR) to assess from when on driving a car can be deemed safe again. Methods: Thirty patients (16 women, 14 men, age 66±11 years) who received TKR of the right knee and 45 healthy controls (26 women, 19 men, age 32±9 years) were asked to perform an emergency braking manoeuvre using a driving simulator. Brake pedal force (BPF), neuronal reaction time (NRT), brake reaction time (BRT), and subjective parameters (pain, subjective driving ability) were measured preoperatively as well as 5 days, 3–4, and 6 weeks after TKR. Results: Preoperative NRT was 506±162 ms, BRT 985±356 ms, and BPF 614±292 N. NRT increased to 561±218 ms, BRT to 1091±404 ms and BPF decreased to 411±191 N 5 days after TKR. Three weeks after surgery, NRT was 581±164 ms and BRT 1013±260 ms, while BPF increased to 555±200 N. Only BPF showed signifcant diferences (p<0.01). In week 6, all parameters were restored to baseline levels; patients showed signifcant pain decrease and evaluated their driving abil ity as “good” again. Conclusion: BPF was the only parameter displaying a signifcant postoperative decrease. However, preoperative patients’ baseline levels and subjective confdence in driving ability were only reached 6 weeks after the operation. These results indicate that a minimum waiting period of 6 weeks should be considered before patients can safely participate in road traffic at their individual preoperative safety level again. Level of evidence II

Orthogonal Light-Dependent Membrane Adhesion Induces Social Self-Sorting and Member-Specific DNA Communication in Synthetic Cell Communities

Developing orthogonal chemical communication pathways in diverse synthetic cell communities is a considerable challenge due to the increased crosstalk and interference associated with large numbers of different types of sender-receiver pairs. Herein, the authors control which sender-receiver pairs communicate in a three-membered community of synthetic cells through red and blue light illumination. Semipermeable protein-polymer-based synthetic cells (proteinosomes) with complementary membrane-attached protein adhesion communicate through single-stranded DNA oligomers and synergistically process biochemical information within a community consisting of one sender and two different receiver populations. Different pairs of red and blue light-responsive protein-protein interactions act as membrane adhesion mediators between the sender and receivers such that they self-assemble and socially self-sort into different multicellular structures under red and blue light. Consequently, distinct sender-receiver pairs come into the signaling range depending on the light illumination and are able to communicate specifically without activation of the other receiver population. Overall, this work shows how photoswitchable membrane adhesion gives rise to different self-sorting protocell patterns that mediate member-specific DNA-based communication in ternary populations of synthetic cells and provides a step towards the design of orthogonal chemical communication networks in diverse communities of synthetic cells

Formalism for Multiphoton Plasmon Excitation in Jellium Clusters

We present a new formalism for the description of multiphoton plasmon excitation processes in jellium clusters. By using our method, we demonstrate that, in addition to dipole plasmon excitations, the multipole plasmons (quadrupole, octupole, etc) can be excited in a cluster by multiphoton absorption processes, which results in a significant difference between plasmon resonance profiles in the cross sections for multiphoton as compared to single-photon absorption. We calculate the cross sections for multiphoton absorption and analyse the balance between the surface and volume plasmon contributions to multipole plasmons.Comment: 29 pages, 1 figur
