Solutions with Prescribed Local Blow-up Surface for the Nonlinear Wave Equation
Authors: Cazenave Thierry , Martel Yvan , Zhao Lifeng 
Published: September 2019

AbstractWe prove that any sufficiently differentiable space-like hypersurface ofℝ1+N{{\mathbb{R}}^{1+N}}coincides locally around any of its points with the blow-up surface of a finite-energy solution of the focusing nonlinear wave equation∂t⁢t⁡u-Δ⁢u=|u|p-1⁢u{\partial_{tt}u-\Delta u=|u|^{p-1}u}onℝ×ℝN{{\mathbb{R}}\times{\mathbb{R}}^{N}}, for any1≤N≤4{1\leq N\leq 4}and1<p≤N+2N-2{1<p\leq\frac{N+2}{N-2}}. We follow the strategy developed in our previous work (2018) on the construction of solutions of the nonlinear wave equation blowing up at any prescribed compact set. Here to prove blow-up on a local space-like hypersurface, we first apply a change of variable to reduce the problem to blowup on a small ball att=0{t=0}for a transformed equation. The construction of an appropriate approximate solution is then combined with an energy method for the existence of a solution of the transformed problem that blows up att=0{t=0}. To obtain a finite-energy solution of the original problem from trace arguments, we need to work withH2×H1{H^{2}\times H^{1}}solutions for the transformed problem.
Deconstructing Popular Mythologies about Millennials and Party Identification
Authors: Cluverius John , Dyck Joshua J. 
Published: September 2019

AbstractAmericans born before 1980, called Millennials, are repeatedly treated as a singular voting bloc, but much like the Baby Boomers, have been socialized across a series of very different elections. We develop a theory of millennial political socialization that argues that older Millennials are more tied to the Democratic party and more liberal than their younger counterparts. We use the 2016 Cooperative Congressional Election Study and an original survey of 1274 Americans conducted before the 2016 elections to test this theory. We find some support for our theory; in addition, we find that younger Millennials are socialized by issues of identity politics and culture – specifically on issues of immigration and the role of race in society. This implies a generation that largely favors Democrats, but whose Republicans are more culturally conservative than middle aged Republican voters.
Ab initio theory of the nitrogen-vacancy center in diamond
Authors: Gali Ádám 
Published: September 2019

Abstract
The nitrogen-vacancy (NV) center in diamond is a solid-state defect qubit with favorable coherence time up to room temperature, which could be harnessed in several quantum-enhanced sensor and quantum communication applications, and has a potential in quantum simulation and computing. The quantum control largely depends on the intricate details about the electronic structure and states of the NV center, the radiative and nonradiative rates between these states, and the coupling of these states to external spins, electric, magnetic, and strain fields, and temperature. This review shows how first-principles calculations contributed to understanding the properties of the NV center and briefly discusses the issues to be solved toward the full ab initio description of solid-state defect qubits.

AbstractStructure elucidation is an important and sometimes time-consuming step for natural products research. This step has evolved in the past few years to a faster and more automated process due to the development of several computational programs and analytical techniques. In this paper, the topics of NMR prediction and CASE programs are addressed. Furthermore, the elucidation of natural peptides is discussed.
Functional Reorganization of Local Circuit Connectivity in Superficial Spinal Dorsal Horn with Neuropathic Pain States
Authors: Gong Nian , Hagopian Garo , Holmes Todd C. , Luo Z. David , Xu Xiangmin 
Published: September 2019

AbstractThe spinal dorsal horn is the first relay structure coding for pain transmission and modulation. Previous anatomical and electrophysiological studies have examined spinal dorsal horn circuit connections and network activity. Further work is required to understand spinal cord sensory information processing that underlies pathological neuropathic pain states. Our previous studies suggest that peripheral nerve injury enhances presynaptic excitatory input onto spinal superficial dorsal horn neurons, which in turn contributes to pathologic nociception. The potential changes in local postsynaptic circuits in the dorsal horn that lead to pathologically heightened behavioral responses to pain remain largely unexplored. We combined whole-cell electrophysiological recordings with laser-scanning photostimulation to test whether peripheral nerve injury in the spinal nerve ligation (SNL) mouse model of neuropathic pain leads to alterations in the functional connectivity of spinal cord circuits including lamina II excitatory interneurons. Here we show that SNL enhances excitation and decreases inhibition to lamina II excitatory interneurons along with their increased glutamate-evoked excitability. The enhanced excitatory postsynaptic input and connectivity evoked by SNL eventually return to normal levels concurrently with the resolution of the neuropathic pain states. The physiological pattern highly correlates with mouse pain behaviors following SNL, supporting a neurophysiological mechanism of central sensitization and neuropathic pain that is functionally localized to the spinal dorsal horn. Together, these data support that SNL induces functional changes in synaptic input and connectivity to lamina II excitatory interneurons that code for pain perception, and thus provide new insights into the mechanism and locus of pain hypersensitivity.
Limits to Genomic Divergence Under Sexually Antagonistic Selection
Authors: Kasimatis Katja R , Ralph Peter L , Phillips Patrick C 
Published: September 2019

AbstractSince the autosomal genome is shared between the sexes, sex-specific fitness optima present an evolutionary challenge. While sexually antagonistic selection might favor different alleles within females and males, segregation randomly reassorts alleles at autosomal loci between sexes each generation. This process of homogenization during transmission thus prevents between-sex allelic divergence generated by sexually antagonistic selection from accumulating across multiple generations. However, recent empirical studies have reported high male-female FST statistics. Here, we use a population genetic model to evaluate whether these observations could plausibly be produced by sexually antagonistic selection. To do this, we use both a single-locus model with nonrandom mate choice, and individual-based simulations to study the relationship between strength of selection, degree of between-sex divergence, and the associated genetic load. We show that selection must be exceptionally strong to create measurable divergence between the sexes and that the decrease in population fitness due to this process is correspondingly high. Individual-based simulations with selection genome-wide recapitulate these patterns and indicate that small sample sizes and sampling variance can easily generate substantial male-female divergence. We therefore conclude that caution should be taken when interpreting autosomal allelic differentiation between the sexes.

Authors: Akhter T. , Alim M. A. A. 
Published: September 2019

The effects of pressure work with radiation heat loss on natural convection flow on a sphere have been investigated in this paper. The governing boundary layer equations are first transformed into a non-dimensional form and the resulting nonlinear partial differential equations are then solved numerically using finite-difference method with Keller-box scheme. We have focused our attention on the evaluation of shear stress in terms of local skin friction and rate of heat transfer in terms of local Nusselt number, velocity as well as temperature profiles. Numerical results have been shown graphically and tabular form for some selected values of parameters set consisting of radiation parameter Rd, pressure work parameter Ge, surface temperature parameter θw and the Prandtl number Pr.
Stability analysis in a delayed SIR epidemic model with a saturated incidence rate
Authors: Kaddar A. 
Published: September 2019

We formulate a delayed SIR epidemic model by introducing a latent period into susceptible, and infectious individuals in incidence rate. This new reformulation provides a reasonable role of incubation period on the dynamics of SIR epidemic model. We show that if the basic reproduction number, denoted, R0, is less than unity, the diseasefree equilibrium is locally asymptotically stable. Moreover, we prove that if R0 > 1, the endemic equilibrium is locally asymptotically stable. In the end some numerical simulations are given to compare our model with existing model.

Solution of the Davey–Stewardson equation using homotopuy analysis method
Authors: Jafari H. , Alipour M. 
Published: September 2019

In this paper, the homotopy analysis method (HAM) proposed by Liao is adopted for solving Davey–Stewartson (DS) equations which arise as higher dimensional generalizations of the nonlinear Schrödinger (NLS) equation. The results obtained by HAM have been compared with the exact solutions and homotopy perturbation method (HPM) to show the accuracy of the method. Comparisons indicate that there is a very good agreement between the HAM solutions and the exact solutions in terms of accuracy.
Exact solutions for the unsteady rotational flow of a generalized second grade fluid through a circular cylinder
Authors: Kamran M. , Imran M. , Athar M. 
Published: September 2019

Here the velocity field and the associated tangential stress corresponding to the rotational flow of a generalized second grade fluid within an infinite circular cylinder are determined by means of the Laplace and finite Hankel transforms. At time t = 0 the fluid is at rest and the motion is produced by the rotation of the cylinder around its axis with a time dependent angular velocity Ωt. The solutions that have been obtained are presented under series form in terms of the generalized G-functions. The similar solutions for the ordinary second grade and Newtonian fluids, performing the same motion, are obtained as special cases of our general solution.
Run up flow of a couple stress fluid between parallel plates
Authors: Devakar M. , Iyengar T. K. V. K. V. 
Published: September 2019

Consider the flow of an incompressible fluid between two parallel plates, initially induced by a constant pressure gradient. After steady state is attained, the pressure gradient is suddenly with drawn while the plates are impulsively started simultaneously. The arising flow is referred to as run up flow and the present paper aims at studying this flow in the context of a couple stress fluid. Using Laplace transform technique, the expression for velocity is obtained in Laplace transform domain which is later inverted to the space time domain using a numerical approach. The variation of velocity with respect to various flow parameters is presented through graphs.
State-feedback stabilization for stochastic high-order nonlinear systems with a ratio of odd integers power
Authors: Liu L. , Duan N. 
Published: September 2019

This paper investigates the problem of globally asymptotically stable in probability by state-feedback for a class of stochastic high-order nonlinear systems with a ratio of odd integers power. By extending the adding a power integrator technique and choosing an appropriate Lyapunov function, a linear smooth state-feedback controller is explicitly constructed to render the system globally asymptotically stable in probability. Furthermore, we address the problem of state-feedback inverse optimal stabilization in probability. A simulation example is provided to show the effectiveness of the proposed approach.

Israel’s Violations of the International Agreement in Siyasah Kharijiyyah (Study of Israeli-Palestinian Peace Agreement 1993-2007)
Authors: Muchtar Masyrofah , Salam Nahrowi 
Published: September 2019

The implementation of the principle of Pacta Sunt Servanda in every international agreement is crucial, considering that the principle necessitates both parties to comply with the agreement. However, in the case of a peace agreement between Israel and Palestine, the fact shows the opposite. This has been due to the violation of the agreement by Israel between 1993-2007. Employing a normative-empirical approach, this study analyzes Israel’s violations against the Israeli-Palestinian peace agreement between 1993-2007, which contradict the principle of Pacta Sunt Servanda and the Siyasah Kharijiyya concept. This study reveals that Israel neglected the principle of Pacta Sunt Servanda in the peace agreement with Palestine. The absence of sanctions for Israel shows that the International Court of Justice has not been able to provide legal certainty for the Palestinian people. Implementasi asas Pacta Sunt Servanda mutlak ada dalam setiap perjanjian internasional. Asas ini sebagai landasan bahwa perjanjian tersebut wajib dipatuhi kedua belah pihak. Namun, faktanya sangatlah bertolak belakang dengan yang diharapkan. Pada perjanjian damai Israel-Palestina, banyak pelanggaran yang dilakukan Israel pada perjanjian damai tersebut terutama kurun waktu 1993–2007. Pada masa itu, telah terjadi rangkaian perjanjian damai antara Israel-Palestina, namun pihak Israel yang selalu melanggar hasil kesepakatan perjanjian tersebut. Dengan pendekatan normatif-empiris, penelitian ini menganalisis pelanggaran Israel pada perjanjian damai Israel-palestina dalam kurun waktu tahun 1993– 2007. Pelanggaran tersebut bertentangan dengan asas Pacta Sunt Servanda dalam konsep perjanjian internasional dan Siyasah Kharijiyyah pada kajian Fikih Siyasah. Temuan penelitian menjelaskan bahwa Israel tidak mengindahkan asas Pacta Sunt Servanda dalam melakukan perjanjian damai dengan Palestina. Tidak ada sanksi terhadap Israel memperlihatkan bahwa Mahkamah Internasional belum dapat memberikan kepastian hukum terhadap rakyat Palestina.

A MATA COMO ESPAÇO DE ENCANTARIA: UMA RELAÇÃO COM A PENTECOSTALIDADE
Authors: Moura Rodolfo , Moraes Manoel Ribeiro de 
Published: September 2019

Falar das presentes e diversificadas influências religiosas que o pentecostalismo herdou durante sua formação histórica requer uma análise abrangente. Contudo, o artigo tem a proposição de construir apenas uma breve análise que provoque o debate acerca da mata como espaço de encantaria na cosmovisão pentecostal, sobretudo dos pentecostais que frequentam a vigília da mata, a qual comumente é denominada de “oração do monte” . Esse tipo de encontro ocorre, semanalmente, em uma zona de mata, no bairro de Val-de-Cães, em Belém. Dessa forma, a abordagem objetiva compreender possíveis elementos de ressignificação que o grupo frequentador faz de códigos da cultura religiosa dos povos tradicionais da Amazônia, onde ecoa, em sua forma de expressão religiosa, a importância da mata na qualidade de espaço mágico-religioso, logo, com traços de influência cultural xamânica. Desse modo, a abordagem atende o método qualitativo, produzido mediante observação participante e revisão bibliográfica, esta, especificamente, sobre a temática pentecostal das encantarias e do sincretismo, as quais ajudam na compreensão dessa relação da pentecostalidade com a mata, exteriorizada na vigília.

Published: September 2019

WstępAby obniżyć częstość występowania próchnicy zębów w Żywcu, władze samorządowe wdrożyły program dedykowany dzieciom w wieku 4–15 lat. Program obejmował działania edukacyjne i profilaktyczne (badanie jamy ustnej oraz lakowanie I i II stałych zębów trzonowych). Celem pracy było zmierzenie skuteczności programu zdrowotnego.Materiał i metodyW badaniu wzięli udział 12-letni uczniowie: z miasta Żywiec objęci programem profilaktycznym (grupa P; n = 441); z miasta Żywiec nieobjęci takim programem (grupa CT; n = 131) oraz ze wsi w powiecie żywieckim, również nieuczestniczący w programie (grupa CR; n = 135). Skuteczność programu była oceniana na podstawie wiedzy dzieci na temat zdrowia jamy ustnej oraz oceny stanu uzębienia, w szczególności pierwszych i drugich zębów trzonowych stałych.WynikiDzieci z grupy P miały większą wiedzę (p < 0,001), obserwowano u nich niższą częstotliwość próchnicy zębów stałych (p < 0,001), niższe średnie wartości DMFT (1,3; p < 0,001) i DMFS (1,4; p < 0,001), niższe wartości SiC (3,2; p < 0,001) oraz wyższe wskaźniki lakowania I (p < 0,001) i II (p < 0,001) zębów trzonowych niż w obu grupach kontrolnych. Dla porównania w grupie CT: DMFT = 4,5; DMFS = 5,2; SiC = 7,2, w grupie CR: DMFT = 3,5;
DMFS = 4,3; SiC = 7,0. Wskaźnik leczenia zębów w grupie CR (0,44) był znacznie niższy niż w grupach P (0,80) i CT (0,76).WnioskiRealizacja programu profilaktycznego o takim charakterze mogłaby przynieść korzyści nie tylko w Polsce, lecz także w krajach, w których stan zdrowia jamy ustnej jest bardzo niekorzystny.
