d0 Ferromagnetic Interface Between Non-magnetic Perovskites

We use computational and experimental methods to study d0 ferromagnetism at a charge- imbalanced interface between two perovskites. In SrTiO3/KTaO3 superlattice calculations, the charge imbalance introduces holes in the SrTiO3 layer, inducing a d0 ferromagnetic half-metallic 2D electron gas at the interface oxygen 2p orbitals. The charge imbalance overrides doping by vacancies at realistic concentrations. Varying the constituent materials shows ferromagnetism to be a gen- eral property of hole-type d0 perovskite interfaces. Atomically sharp epitaxial d0 SrTiO3/KTaO3, SrTiO3 /KNbO3 and SrTiO3 /NaNbO3 interfaces are found to exhibit ferromagnetic hysteresis at room temperature. We suggest the behavior is due to high density of states and exchange coupling at the oxygen t1g band in comparison with the more studied d band t2g symmetry electron gas.Comment: 5 pages, 5 figure

A geometric Newton method for Oja's vector field

Newton's method for solving the matrix equation $F(X)\equiv AX-XX^TAX=0$ runs up against the fact that its zeros are not isolated. This is due to a symmetry of $F$ by the action of the orthogonal group. We show how differential-geometric techniques can be exploited to remove this symmetry and obtain a ``geometric'' Newton algorithm that finds the zeros of $F$. The geometric Newton method does not suffer from the degeneracy issue that stands in the way of the original Newton method

Hubungan Kompetensi dan Disiplin Kerja Terhadap Kinerja Pegawai

Beberapa permasalahan ASN di Kabupaten Merauke adalah nilai kinerja (SKP) setiap tahunnya  menurun, penempatan pegawai yang tidak sesuai dengan kompetensinya, ketidaksesuaian pendidikan dengan uraian tugas yang dibebankan, dan tingkat kehadiran pegawai pada jam kerja yang kurang.Tujuan dari penelitian ini adalah  untuk menjelaskan hubungan antara kompetensi dan disiplin kerja dengan kinerja pegawai di Kantor Pemerintah Kabupaten Merauke. Metode penelitian yang digunakan adalah dengan pendekatan kuantitatif dengan analisis bivariat yaitu korelasi Somers’d dan pengolahannya menggunakan bantuan sofware SPSS 21. Populasi dalam penelitan ini adalah meliputi seluruh pegawai di Pemerintah Daerah Kabupaten Merauke yaitu sejumlah 5.453 orang. Untuk Jumlah sampel dalam penelitian ini ditentukan menggunakan menggunakan rumus slovin yaitu sejumlah 372 responden. Hasil penelitian ini menemukan bahwa kompetensi secara signifikan terdapat asosiasi yang kuat dengan kinerja pegawai di Kantor Pemerintah Kabupaten Merauke. Hal ini menunjukan bahwa  ketika kompetensi pegawai semakain baik maka akan kinerja pegawai juga semakin baik, dan disiplin kerja secara signifikan terdapat asosiasi yang kuat dengan kinerja pegawai  di  Kantor Pemerintah Kabupaten Merauke. Hal ini menunjukan bahwa  ketika disiplin kerja pegawai semakain baik maka akan kinerja pegawai juga semakin baik

10th international scientific conference business and management 2018

The purpose of the study is to investigate and elaborate the dynamic capabilities needed to manage disruptive business. This paper is a conceptual paper. Firstly, authors present key concept of technological disruption, which is highly relevant for modern corporate foresight. Nowadays, in the market conditions of corporate foresight, VUCA (Volatility, Uncertainty, Complexity, and Ambiguity) approach has a significant role. Secondly, the rigor of this paper is to combine scientific discussion of technological disruption with the VUCA approach and dynamic capabilities of smart disruptor. The special focus of this article is the challenges of orchestration of dynamic capabilities in the special conditions of VUCA business environment and disruptive competition. The method/design of this study is a conceptual paper. The results: We evaluate the role of competence gaps identification inside a firm: The technology gaps, market gaps and business model gaps in modern business leadership. Our principal conclusion is to present tools to manage the dynamic capabilities in the VUCA and in the disruptive business environment. Further, we will present the pleminary definition of the smart disruptor

Radial Velocity Studies of Close Binary Stars. IX

Radial-velocity measurements and sine-curve fits to the orbital velocity variations are presented for the eighth set of ten close binary systems: AB And, V402 Aur, V445 Cep, V2082 Cyg, BX Dra, V918 Her, V502 Oph, V1363 Ori, KP Peg, V335 Peg. Half of the systems (V445 Cep, V2082 Cyg, V918 Her, V1363 Ori, V335 Peg) were discovered photometrically by the Hipparcos mission and all systems are double-lined (SB2) contact binaries. The broadening function method permitted improvement of the orbital elements for AB And and V502 Oph. The other systems have been observed for radial velocity variations for the first time; in this group are five bright (V<7.5) binaries: V445 Cep, V2082 Cyg, V918 Her, KP Peg and V335 Peg. Several of the studied systems are prime candidates for combined light and radial-velocity synthesis solutions.Comment: 17+ pages, 2 tables, 4 figure

Benefit of measuring vedolizumab concentrations in inflammatory bowel disease patients in a real-world setting

Objectives We set out to determine the reasons for serum vedolizumab (VDZ) trough concentration (TC) measurements in inflammatory bowel disease (IBD) patients and to evaluate treatment modifications after therapeutic drug measurement (TDM). We also evaluated the effect of increased dosing on patients' response to VDZ therapy. Methods We performed a retrospective cohort study of IBD patients who received VDZ therapy at Helsinki University Hospital and whose VDZ levels were measured between June 2014 and December 2018. Results Altogether, 90 patients (32 Crohn's disease and 58 ulcerative colitis) and 141 VDZ TC measurements were included. 24.1% of measurements took place during induction and 75.9% during the maintenance phase. During induction, 64.7% reached the target TC >20 mu g/ml. During maintenance therapy, 82.2% of VDZ TCs were within or exceeded the suggested target range of 5-15 mu g/ml. Reasons for TDM were: secondary nonresponse (44.0%), assessment of adequate VDZ TC (25.5%), primary nonresponse (12.8%), adverse events (6.4%), and other (11.3%). No treatment changes occurred after 60.3% of VDZ measurements. Increased dose frequency was used after 25.5% of VDZ measurements and 33.3% of these patients experienced improvement. Altogether, 31 (34.4%) patients discontinued the therapy due to inadequate treatment response. No anti-vedolizumab antibodies were detected. Conclusions During the maintenance of VDZ therapy, the majority of VDZ TCs were within the suggested range. Measurement of VDZ TC did not lead to any treatment changes in two-thirds of patients. Dose optimization occurred in a quarter of patients and a third of them benefited from it.Peer reviewe
