The Sand Creek Massacre
Authors: Kerr Asa M.
Published: February 2019

The 1864 massacre of Cheyenne and Arapaho Native Americans by a Colorado territorial militia regiment is investigated through a genocidal lens, both as a component of the larger destruction of Native American cultures and peoples by U.S. forces and in its own specific economic and ideological context. Using the work of many other scholars in the field of genocide studies and the established definition of genocide provided by the UN Convention on Genocide, this essay initially defines how the gradual dwindling of Native American populations from the onset of European colonization through the next three centuries can be viewed as genocide. Following this groundwork, the question of culpability for the massacre is brought forth and three main categories of suspects are identified: local government and military leaders, the White settler population of Colorado, and the U.S. federal government. All three potential areas of culpability are shown to possess varying degrees of responsibility in effecting the massacre. Upon conclusion of the investigation, there is a brief discussion of possible means of reconciliation accompanied by an examination of the nature of current reconciliation efforts.
The Performance of Fixed-Horizon, Look-Ahead Procedures Compared to Backward Induction in Bayesian Adaptive-Randomization Decision-Theoretic Clinical Trial Design
Authors: Lipsky Ari M. , Lewis Roger J.
Published: February 2019

Designing optimal, Bayesian decision-theoretic trials has traditionally required the use of computationally-intensive backward induction. While methods for addressing this barrier have been put forward, few are both computationally tractable and non-myopic, with applications of the Gittins index being one notable example. Here we explore the look-ahead approach with adaptive-randomization, with designs ranging from the fully myopic to the fully informed. We compare the operating characteristics of the look-ahead designed trials, in which decision rules are based on a fixed number of future blocks, with those of trials designed using traditional backward induction. The less-myopic designs performed well. As the designs become more myopic or the trials longer, there were disparities in regions of the decision space that are transition zones between continuation and stopping decisions. The more myopic trials generally suffered from early stopping as compared to the less myopic and backward induction trials. Myopic trials with adaptive randomization also saw as many as 28 % of their continuation decisions change to a different randomization ratio as compared to the backward induction designs. Finally, early stages of myopic-designed trials may have disproportionate effect on trial characteristics.
Causal loops: Logically consistent correlations, time travel, and computation
Authors: Baumeler Ämin
Published: February 2019

Causal loops are loops in cause-effect relations, where, say for two events A, B, the event A is a cause of B and, vice versa, B is a cause of A. Such loops are traditionally ruled out due to potential logical problems, e. g., where an effect suppresses its own cause. Motivated by our current physical theories, we show that not only causal loops exist that are logically consistent, but that these loops are computationally tame and help to further investigate on the theoretical foundations of time travel. Causal loops do not necessarily pose problems from a logics, computer-science, and physics point of view. This opens their potential applicability in various fields from philosophy of language to computer science and physics.
KGSA: A Gravitational Search Algorithm for Multimodal Optimization based on K-Means Niching Technique and a Novel Elitism Strategy
Authors: Golzari Shahram , Zardehsavar Mohammad Nourmohammadi , Mousavi Amin , Saybani Mahmoud Reza , Khalili Abdullah , Shamshirband Shahaboddin
Published: February 2019

Gravitational Search Algorithm (GSA) is a metaheuristic for solving unimodal problems. In this paper, a K-means based GSA (KGSA) for multimodal optimization is proposed. This algorithm incorporates K-means and a new elitism strategy called “loop in loop” into the GSA. First in KGSA, the members of the initial population are clustered by K-means. Afterwards, new population is created and divided in different niches (or clusters) to expand the search space. The “loop in loop” technique guides the members of each niche to the optimum direction according to their clusters. This means that lighter members move faster towards the optimum direction of each cluster than the heavier members. For evaluations, KGSA is benchmarked on well-known functions and is compared with some of the state-of-the-art algorithms. Experiments show that KGSA provides better results than the other algorithms in finding local and global optima of constrained and unconstrained multimodal functions.
The fourth order strongly noncanonical operators
Authors: Baculikova Blanka , Dzurina Jozef
Published: February 2019

It is shown that the strongly noncanonical fourth order operator

$$\begin{array}{}
\displaystyle
\mathcal
{L}\,y=\left(r_3(t)\left(r_2(t)\left(r_1(t)y'(t)\right)'\right)'\right)'
\end{array}$$

can be written in essentially unique canonical form as

$$\begin{array}{}
\displaystyle
\mathcal
{L}\,y = q_4(t)\left(q_3(t)\left(q_2(t)\left(q_1(t)\left(q_0(t)y(t)\right)'\right)'\right)'\right)'.
\end{array}$$

The canonical representation essentially simplifies examination of the fourth order strongly noncanonical equations

$$\begin{array}{}
\displaystyle
\left(r_3(t)\left(r_2(t)\left(r_1(t)y'(t)\right)'\right)'\right)'+p(t)y(\tau(t))=0.

Numerical method for 3D two-component isothermal compressible flows with application to digital rock physics
Authors: Balashov Vladislav , Savenkov Evgenii , Zlotnik Alexander
Published: February 2019

We propose a numerical algorithm for simulations of two-component viscous compressible isothermal flows with surface effects in 3D domains of complex shape with voxel representation of geometry. The basic mathematical model is the regularized system of Navier–Stokes–Cahn–Hilliard equations. Simulations of droplet spreading over a flat base and displacement of one liquid by another one in a pore space of real rock sample are carried out. The simulation results demonstrate the applicability and good efficiency of the used system of equations, the corresponding difference scheme, and its implementation algorithms for numerical solution of the considered class of problems.
Robust regularization of topology optimization problems with a posteriori error estimators
Authors: Ovchinnikov George V. , Zorin Denis , Oseledets Ivan V.
Published: February 2019

Topological optimization finds a material density distribution minimizing a functional of the solution of a partial differential equation (PDE), subject to a set of constraints (typically, a bound on the volume or mass of the material).

Using a finite elements discretization (FEM) of the PDE and functional we obtain an integer programming problem. Due to approximation error of the FEM discretization, optimization problem becomes mesh-depended and possess false, physically inadequate optimums, while functional value heavily depends on the fineness of discretization scheme used to compute it. To alleviate this problem, we propose regularization of given functional by error estimate of the FEM discretization. This regularization provides robustness of solutions and improves obtained functional values as well.

While the idea is broadly applicable, in this paper we apply our method to the heat conduction optimization. Problems of this type are of practical importance in design of heat conduction channels, heat sinks and other types of heat guides.
Analytical Solutions and Integrable Structure of the Time-Dependent Harmonic Oscillator With Friction
Authors: An Hongli , Chan Waihong , Li Biao , Yuen Manwai
Published: February 2019

By employing the Madelung transformation, the time-dependent harmonic oscillator with friction described by the Schrödinger equation is reduced to a hydrodynamic system. An exponential elliptic vortex ansatz is introduced, and thereby a finite-dimensional nonlinear dynamical system is obtained. Time-modulated physical variables corresponding to the divergence, spin, shear, and normal deformation rates of the Madelung velocity field are introduced, and the dynamical system is reducible to a form amenable to general solutions. In particular, three typical elliptical vortex solutions termed pulsrodons are derived, and their behaviours are simulated. These solutions have recently found applications in oceanic and atmospheric dynamics. Moreover, it is shown that the harmonic oscillator with friction has an underlying integrable structure of Ermakov–Hamiltonian type.

The changes of landuse in watershed area of Beringin river, from rubber forest into housing area of Bukit Semarang Baru (BSB), is suspected as the cause of increase in water discharge into Beringin river. The research objective is to describe the rise in water discharge of Beringin river due to the changes of landuse in the watershed area of Beringin river which currently inhibited by BSB housing. According to statistics criteria, the distribution of maximum daily rainfall frequency for repeated period of 2, 5, 10 and 20 years was analyzed by distribution frequency Gumbel. Research result shows that there is an increase in water discharge of Beringin river due to the rise of runoff water as the consequence of land use change in BSB area. Ten years discharge before the land use change was = 7,94 m /dt, then raised into 113,49 m3 /dt following the change, so the water discharge of Beringin river is = 121,43 m3 /dt. This impact analysis can be an early information for the future researcher to find the solution of flood phenomena in Semarang.Perubahan tataguna lahan di sub DAS Beringin, dari hutan karet menjadi kawasan hunian Bukit Semarang Baru (BSB) diduga penyebab meningkatnya aliran limpasan yang masuk sungai Beringin.
