AbstractP systems are a model of compartmentalized multiset rewriting inspired by the structure of living cells and the way they function. In this paper, we focus of a variant in P systems in which membranes have limited capacity, i.e., the number of objects they may hold is limited by a fixed bound. This feature corresponds to an important physical property of cellular compartments. We propose several possible semantics of limited capacity and show that one of them allows real-time simulations of partially blind register machines, while the other one allows for obtaining computational completeness.

AbstractThe optical refractive index of cellular components is generally not a property considered amenable to manipulation in microscopy as this is an intrinsic physical property of materials. Here we show that by targeting cephalopod reflectin protein nanoparticles one can manipulate the optical refractive index of mammalian cellular compartments. We further demonstrate that refractive index alteration based contrast agents can be utilized for dark field microscopy and quantitative phase contrast holotomography. Additionally we have molecularly cloned novel reflectins with improved and novel optical properties.

This aims to review and analyze the Jordanian experiment in the developmental regional planning field within the decentralized managerial methods, which is considered one of the primary basic provisions for applying and success of this kind of planning. The study shoed that Jordan has passed important steps in the way for implanting the decentralized administration, but these steps are still not enough to established the effective and active regional planning. The study reveled that there are many problems facing the decentralized regional planning in Jordan, despite of the clear goals that this planning is trying to achieve. These problems have resulted from the existing relationship between the decentralized administration process’ dimensions from one side, and between its levels which ranged from weak to medium decentralization from the other side, In spite of the official trends aiming at applying more of the decentralized administrative policies, still high portion of these procedures are theoretical, did not yet find a way to reality. Because any progress or success at the level of applying the decentralized administrative policies doubtless means greater effectiveness and influence on the development regional planning in life of the residents in the kingdom’s different regions. So, it is important to go a head in applying more steps and decentralized administrative procedures, gradually and continuously to guarantee the control over any negative effects that might result from Appling this kind of systems.   © 2018 JASET, International Scholars and Researchers Association

The objectives of the research were to describe the types of speech acts used in televised political debates of governor candidates of North Sumatera, to derive the dominant type of speech acts used in televised political debates of governor candidates of North Sumatera and to elaborate the way of five governor candidates of North Sumatera use speech acts in televised political debates. This research was conducted by applying descriptive qualitative research. The findings show that there were only four types of speech acts used in televised political debates, Debat Pemilukada Sumatera Utara and Uji Publik Cagub dan Cawagub Sumatera Utara, they were assertives, directives, commissives and expressives. The dominant type of speech acts used in both televised political debates was assertives, with 82 utterances or 51.6% in Debat Pemilukada Sumatera Utara and 36 utterances or 41.37% in Uji Publik Cagub dan Cawagub Sumatera Utara. The way of governor candidates of North Sumatera used speech acts in televised political debates is in direct speech acts, they spoke straight to the point and clearly in order to make the other candidates and audiences understand their utterances.   Keywords: Governor Candidate; Political Debate; Speech Acts

The cultural environment of Ibn al-Arabi is in Andalusia, Spain today. There, on the one hand, Sufism, on the other hand, thinks like Ibn Bacce (Death.1138), Ibn Tufeyl (Death186), Ibn Rushd (Death.1198) and the knowledge and philosophy inherited by scholars, . Ibn al-Arabi (1165-1240), that was the effect of all this; But more mystic (mystic) circles came out of the way. This work, written by Ibn al-Arabi's works (especially Futuhati Mekkiye), also contains a very small number of other relevant sources.

<div>Photoactivatable dyes enable single-molecule imaging in biology. Despite progress in the development of new fluorophores and labeling strategies, many cellular compartments remain difficult to image beyond the limit of diffraction in living cells. For example, lipid droplets, which are organelles that contain mostly neutral lipids, have eluded single-molecule imaging. To visualize these challenging subcellular targets, it is necessary to develop new fluorescent molecular devices beyond simple on/off switches. Here, we report a fluorogenic molecular logic gate that can be used to image single molecules associated with lipid droplets with excellent specificity. This probe requires the subsequent action of light, a lipophilic environment and a competent nucleophile to produce a fluorescent product. The combination of these requirements results in a probe that can be used to image the boundary of lipid droplets in three dimensions with resolutions beyond the limit of diffraction. Moreover, this probe enables single-molecule tracking of lipids within and between droplets in living cells.</div>

The Way

This chapter considers Freedman’s contribution to scholarship and the nascent elements of a school of thought relevant to both academic and policy realms, as well as introducing a more skeptical and critical approach to the subject’s scholarship. It considers Freedman’s engagement with the policy world and why this has managed to be both extensive and successful, as well as its outcomes. It also introduces discussion of possible challenges to Freedman’s work, presenting a balancing perspective to positive appreciations of his oeuvre. The chapter concludes by indicating the weaknesses of such challenges and reaffirms the sense of a school of thought informed by a distinctive approach. This is the blend of scripturalism and constructivism, on one side, with realism, on the other, that is the hallmark of the nascent school, and the way in which it is germane in both academic and policy domains.

The Way

This chapter spans Freedman’s earliest focus on nuclear weapons and his development of strategic scripts as an analytical tool over three decades later. It discusses the way in which opposing logics of disarmament and armament co-existed in relation to nuclear weapons. It deploys the notion of strategic scripts to explain the contradictions inherent in approaches to nuclear disarmament, developing the concept of strategic scripts as it does so. The notion of scripts can be used to explore and even to promote nuclear disarmament. Two scripts, one of ‘stable reduction’, the other of ‘disarmament’, each serve to frame thinking. These scripts and the interactions they generate facilitate understanding of the way in which opposite instinctive reactions and, stemming from these, scripts about nuclear weapons co-exist, but are fragile as either an analytical or a strategic tool.
