Revaluasi Aset Untuk Tujuan Perpajakan, Ambil Atau Jangan

The Government has launched a policy of taxation through the Minister of Finance numbered 191/PMK.010/2015 on Revaluation of Fixed Assets Proposed in the Year 2015 and 2016. Impact of revaluation, automatically has consequences to the increase on depreciation expenses of fixed assets are charged to the profit and loss next period, so company will have benefit from the revaluation of these assets. But Fixed Assets Revaluation for tax purposes is not free. There are taxes to be paid, especially if the asset after revaluation is sold to a third party, then the taxpayer will be charged as additional income tax. If the company still wants to take the program of the asset revaluation, fixed assets after the revaluation prohibited for sale to another party until the depreciation of assets ending

Group Chase and Escape

We describe here a new concept of one group chasing another, called "group chase and escape", by presenting a simple model. We will show that even a simple model can demonstrate rather rich and complex behavior. In particular, there are cases in which an optimal number of chasers exists for a given number of escapees (or targets) to minimize the cost of catching all targets. We have also found an indication of self-organized spatial structures formed by both groups.Comment: 13 pages, 12 figures, accepted and to appear in New Journal of Physic

Chiral Modulations in Curved Space I: Formalism

The goal of this paper is to present a formalism that allows to handle four-fermion effective theories at finite temperature and density in curved space. The formalism is based on the use of the effective action and zeta function regularization, supports the inclusion of inhomogeneous and anisotropic phases. One of the key points of the method is the use of a non-perturbative ansatz for the heat-kernel that returns the effective action in partially resummed form, providing a way to go beyond the approximations based on the Ginzburg-Landau expansion for the partition function. The effective action for the case of ultra-static Riemannian spacetimes with compact spatial section is discussed in general and a series representation, valid when the chemical potential satisfies a certain constraint, is derived. To see the formalism at work, we consider the case of static Einstein spaces at zero chemical potential. Although in this case we expect inhomogeneous phases to occur only as meta-stable states, the problem is complex enough and allows to illustrate how to implement numerical studies of inhomogeneous phases in curved space. Finally, we extend the formalism to include arbitrary chemical potentials and obtain the analytical continuation of the effective action in curved space.Comment: 22 pages, 3 figures; version to appear in JHE

Synthesis, XRD and HS-Analysis

An efficient microwave-assisted one-step synthetic route toward Mannich bases is developed from 4-hydroxyacetophenone and different secondary amines in quantitative yields, via a regioselective substitution reaction. The reaction takes a short time and is non-catalyzed and reproducible on a gram scale. The environmentally benign methodology provides a novel alternative, to the conventional methodologies, for the synthesis of mono- and disubstituted Mannich bases of 4-hydroxyacetophenone. All compounds were well-characterized by FT-IR, 1H NMR, 13C NMR, and mass spectrometry. The structures of 1-{4-hydroxy-3-[(morpholin-4-yl)methyl]phenyl}ethan-1-one (2a) and 1-{4-hydroxy-3-[(pyrrolidin-1-yl)methyl]phenyl}ethan-1-one (3a) were determined by single crystal X-ray crystallography. Compound 2a and 3a crystallize in monoclinic, P21/n, and orthorhombic, Pbca, respectively. The most characteristic features of the molecular structure of 2a is that the morpholine fragment adopts a chair conformation with strong intramolecular hydrogen bonding. Compound 3a exhibits intermolecular hydrogen bonding, too. Furthermore, the computed Hirshfeld surface analysis confirms H-bonds and π–π stack interactions obtained by XRD packing analyses

Holographic two dimensional QCD and Chern-Simons term

We present a holographic realization of large Nc massless QCD in two dimensions using a D2/D8 brane construction. The flavor axial anomaly is dual to a three dimensional Chern-Simons term which turns out to be of leading order, and it affects the meson spectrum and holographic renormalization in crucial ways. The massless flavor bosons that exist in the spectrum are found to decouple from the heavier mesons, in agreement with the general lore of non-Abelian bosonization. We also show that an external dynamical photon acquires a mass through the three dimensional Chern-Simons term as expected from the Schwinger mechanism. Massless two dimensional QCD at large Nc exhibits anti-vector-meson dominance due to the axial anomaly.Comment: 22 page

Towards azimuthal anisotropy of direct photons

Intensive radiation of magnetic bremsstrahlung type (synchrotron radiation) resulting from the interaction of escaping quarks with the collective confining colour field is discussed as a new possible mechanism of observed direct photon anisotropy.Comment: 3 pages, Comments and references added, accepted to JETP Letters (Pis'ma v ZhETF

Synthesis, molecular docking and biochemical analysis of aminoalkylated naphthalene-based chalcones as acetylcholinesterase inhibitors

Twelve novel chalcones were synthesized using 2-alkyloxy-naphthaldehydes and Mannich bases of 4-hydroxyacetophenone. The chalcones were characterized using FTIR, 1D and 2D NMR and HRMS spectroscopy. Comparative docking analysis was carried out to screen their affinity towards the AChE enzyme (PDB 1EVE). All chalcones showed lower binding energy (-13.06 to -10.43 kcal/mol) against AChE better than donepezil (-10.52 kcal/mol). All chalcones were potent inhibitors towards AChE, with IC50 values ranging between 0.11 and 5.34 nM better than donepezil (IC50 33.4 nM) and selectivity indexes (0.66–23.83), despite the fact that chalcones 10 and 13 were inactive. The structure activity relationship indicated that introducing diethyl amine in ring A of the chalcone skeleton and the propargyl moiety at ring B was a?rmed to be a prospective drug against AChE. The multifunctional properties of chalcone 15 were all advantages that demonstrate an excellent candidate for the development of an effective drug against AChE

Experimental study and high dimensional QSAR modelling of phenylpropanoids of Alpinia galanga as corrosion inhibitors on mild steel

Plant extracts as corrosion inhibitors have been extensively investigated and are found as an alternative to synthetic organic compounds. The corrosion inhibition of mild steel in 1 M HCl by 15 compounds comprising of five phenylpropanoids from Alpinia galanga and other related compounds was explored experimentally using potentiodynamic polarisation procedures. The inhibition efficiencies determined experimentally for the various inhibitors were used in the Quantitative Structure-Activity Relationship (QSAR) study with their molecular descriptors calculated using Dragon software. Penalised multiple linear regression (PMLR) was adopted as the method of variable selection using elastic net penalty. The elastic net results show low mean-squared error of the training set (MSEtrain) of 0.121 and test set (MSEtest) of 0.131. The model obtained can be applied to predict the corrosion inhibition efficiencies of related organic compounds. Results also reveal that the PMLR based on elastic net penalty is effective in dealing with high dimensional data

The Incremental Cooperative Design of Preventive Healthcare Networks

This document is the Accepted Manuscript version of the following article: Soheil Davari, 'The incremental cooperative design of preventive healthcare networks', Annals of Operations Research, first published online 27 June 2017. Under embargo. Embargo end date: 27 June 2018. The final publication is available at Springer via http://dx.doi.org/10.1007/s10479-017-2569-1.In the Preventive Healthcare Network Design Problem (PHNDP), one seeks to locate facilities in a way that the uptake of services is maximised given certain constraints such as congestion considerations. We introduce the incremental and cooperative version of the problem, IC-PHNDP for short, in which facilities are added incrementally to the network (one at a time), contributing to the service levels. We first develop a general non-linear model of this problem and then present a method to make it linear. As the problem is of a combinatorial nature, an efficient Variable Neighbourhood Search (VNS) algorithm is proposed to solve it. In order to gain insight into the problem, the computational studies were performed with randomly generated instances of different settings. Results clearly show that VNS performs well in solving IC-PHNDP with errors not more than 1.54%.Peer reviewe

The Chiral Magnetic Effect and Axial Anomalies

We give an elementary derivation of the chiral magnetic effect based on a strong magnetic field lowest-Landau-level projection in conjunction with the well-known axial anomalies in two- and four-dimensional space-time. The argument is general, based on a Schur decomposition of the Dirac operator. In the dimensionally reduced theory, the chiral magnetic effect is directly related to the relativistic form of the Peierls instability, leading to a spiral form of the condensate, the chiral magnetic spiral. We then discuss the competition between spin projection, due to a strong magnetic field, and chirality projection, due to an instanton, for light fermions in QCD and QED. The resulting asymmetric distortion of the zero modes and near-zero modes is another aspect of the chiral magnetic effect.Comment: 33 pages, 5 figures, to appear in Lect. Notes Phys.
