Abstract:
Abstract. In pursuit of a more systematic and comprehensive framework for personality assessment, we introduce procedures for assessing personality traits at the lowest level: nuances. We argue that constructing a personality taxonomy from the bottom up addresses some of the limitations of extant top-down assessment frameworks (e.g., the Big Five), including the opportunity to resolve confusion about the breadth and scope of traits at different levels of the organization, evaluate unique and reliable trait variance at the item level, and clarify jingle/jangle issues in personality assessment. With a focus on applications in survey methodology and transparent documentation, our procedures contain six steps: (1) identification of a highly inclusive pool of candidate items, (2) programmatic evaluation and documentation of item characteristics, (3) test-retest analyses of items with adequate qualitative and quantitative properties, (4) analysis of cross-ratings from multiple raters for items with adequate retest reliability, (5) aggregation of ratings across diverse samples to evaluate generalizability across populations, (6) evaluations of predictive utility in various contexts. We hope these recommendations are the first step in a collaborative effort to identify a comprehensive pool of personality nuances at the lowest level, enabling subsequent construction of a robust hierarchy – from the bottom up.

Abstract:
In this paper, we extend the notion of (word) derivatives and partial derivatives due to (respectively) Brzozowski and Antimirov to tree derivatives using already known inductive formulae of quotients. We define a new family of extended regular tree expressions (using negation or intersection operators), and we show how to compute a Brzozowski-like inductive tree automaton; the fixed point of this construction, when it exists, is the derivative tree automaton. Such a deterministic tree automaton can be used to solve the membership test efficiently: the whole structure is not necessarily computed, and the derivative computations can be performed in parallel. We also show how to solve the membership test using our (Bottom-Up) partial derivatives, without computing an automaton.

Abstract:
ABSTRACT:In the 2000s, Berlin saw the formation of so-called Baugruppen (construction groups) – associations of small-scale investors who pooled their modest capital to commission an architect and construct a multistorey building in which they would own and occupy a flat. They were mostly middle-class families united by a belief in community values and neighbourly contact as well as the qualities of urban living. This article will present the construction groups as an example of bottom-up architecture in an industrialized western country, in which individual initiatives and user-centred design had to be negotiated within a highly professionalized environment, as well as with contradictory political positions. It will show that construction groups brought together various threads of Berlin's recent urban history: the gradual integration of radical post-1968 lifestyles into mainstream society, the ‘return to the inner city’ connected with the increasing popularity of ‘new tenements’, and the evolution of innovative, post-functionalist architecture.

Abstract:
The bottom-up construction of synthetic cells from molecular components is arguably one of the most challenging areas of research in the life sciences. We review the impact of confining biological systems in synthetic vesicles. Complex cell-like systems require control of the internal pH, ionic strength, (macro)molecular crowding, redox state and metabolic energy conservation. These physicochemical parameters influence protein activity and need to be maintained within limits to ensure the system remains in steady-state. We present the physicochemical considerations for building synthetic cells with dimensions ranging from the smallest prokaryotes to eukaryotic cells.

Abstract:
In the construction industry, there are two methods for constructing basements (Top-Down) and (Bottom-UP). The difference between them lies in the sequence of works, since in the (Bottom-Up) method the end of the excavation work is the necessary condition for the beginning of the substructure construction, and this is different from the (Top Down) method where excavation and construction of the substructure and the superstructure are carried out in parallel, which significantly reduces the project duration but at the same time increases the construction cost. Also there is a difference in terms of use for each of these two methods, for example, it is preferable to use the (Top-Down) in dense urban areas, where there is not enough space for the construction and where there are concerns that the adjacent buildings may be deformed as a result of construction, and this is what the (Bottom-Up) method cannot provide. In order to determine the optimal method from a mathematical point of view, 7 main criteria and 25 sub-criteria were identified, and the Analytic Hierarchy Process was used to solve this multi-criteria problem. Using the Expert Choice software, we found that the (Top-Down) method is preferred by 14.8% more than (Bottom-Up), and a sensitivity analysis was performed to determine which criteria dominated our optimal result.

Full text
Abstract:
Motion metaphors occur at different levels, from prepositional phrases to discourse, including theoretical metaphors. After reviewing Relevance Theory as a bottom-up approach, and Cognitive Linguistics and Segmented Discourse Representation Theory as top-down ones, an integrated approach to metaphor in discourse construction is developed, based on a cognitive operation of connection of lower units into higher ones, similar to subsumption in the Lexical Constructional Model and to chunking in the Usage-Based Approach. In discourse construction, as the analysis of press and poetry examples show, either a motion metaphor may contribute to the discourse structure, or it may result from it. Discourses are packed into text structures; live discourse metaphors develop into text-type metaphors on their way to conventionalization. Metaphor and discourse construction are bottom-up processes, since they result from connection of lower units, but they are also top-down, based on properties of higher units, domains in metaphor and relations in discourse.

Abstract:
The bottom-up approach to miniaturization, which starts from molecules to build up nanostructures, enables the extension of the macroscopic concepts of a device and a machine to molecular level. Molecular-level devices and machines operate via electronic and/or nuclear rearrangements and, like macroscopic devices and machines, need energy to operate and signals to communicate with the operator. Examples of molecular-level photonic wires, plug/socket systems, light-harvesting antennas, artificial muscles, molecular lifts, and light-powered linear and rotary motors are illustrated. The extension of the concepts of a device and a machine to the molecular level is of interest not only for basic research, but also for the growth of nanoscience and the development of nanotechnology.

Abstract:
The rational design of an outer shell is of great significance to promote the photocatalytic efficiency of core-shell structured photocatalysts. Herein, a covalent organic framework (COF) nanoshell was designed and deposited on the cadmium sulfide (CdS) core surface. A typical COF material, TPPA, featuring exceptional stability, was synthesized through interfacial polymerization using 1, 3, 5-triformylphloroglucinol (TP) and p-phenylenediamine (PA) as monomers. The nanoshell endows the CdS@TPPA nanosphere with ordered channels for unimpeded light-harvesting and fast diffusion of reactants/products and well-defined modular building blocks for spatially charge separation. Moreover, the heterojunction formed between CdS and TPPA can further facilitate the effective charge separation at the interface via lower exciton binding energy compared with that of pristine TPPA. By modulating the thickness of TPPA nanoshell, the CdS@TPPA nanosphere photocatalyst with the nanoshell thickness of about 8±1 nm exhibits the highest photocatalytic H2 evolution of 194.1 μmol h-1 (24.3 mmol g-1 h-1, 8 mg), which is superior to most of the reported COF-based photocatalysts. The framework nanoshell in this work may stimulate the thinking about how to design advanced shell architecture in the core-shell structured photocatalysts to achieve coordinated charge and molecule transport.

Abstract:
How synthetic can “synthetic biology” be? A literal interpretation of the name of this new life science discipline invokes expectations of the systematic construction of biological systems with cells being built module by module—from the bottom up. But can this possibly be achieved, taking into account the enormous complexity and redundancy of living systems, which distinguish them quite remarkably from design features that characterize human inventions? There are several recent developments in biology, in tight conjunction with quantitative disciplines, that may bring this literal perspective into the realm of the possible. However, such bottom-up engineering requires tools that were originally designed by nature’s greatest tinkerer: evolution.

We show that for every deterministic bottom-up tree transducer, a unique equivalent transducer can be constructed which is minimal. The construction is based on a sequence of normalizing transformations which, among others, guarantee that non-trivial output is produced as early as possible. For a deterministic bottom-up transducer where every state produces either none or infinitely many outputs, the minimal transducer can be constructed in polynomial time.

Does local oversight improve public service delivery? We study the effect of a mobile phone application that allows citizens to monitor school construction projects in Brazilian municipalities. The app prompts users to submit data about construction sites, sends such crowdsourced information to independent engineers, and contacts the mayors’ offices about project delays. Our results show that the app has a null impact on school construction indicators. Additionally, we find that politicians are unresponsive to individual requests. The results question the impact of bottom-up monitoring on public service performance and suggest that interventions targeted at other groups, or focused on different issues, may produce better policy outcomes.

Abstract:
Bottom-up organic synthesis serves as an efficient method to provide atomically precise heteroatom-doped polycyclic aromatic hydrocarbons (PAHs) with not only well-defined size and edge structures but also specific concentrations and positions of the heteroatoms. We provide a plenary account of the preparation of nitrogen-doped PAHs (N-PAHs) through 1,3-dipolar cycloaddition between different dipolarophiles, as well as pyrazine-type N-doped diaza-hexa-peri-hexabenzocoronene (diaza-HBC). Additionally, we present the synthesis of a class of helical N-charged PAHs, including one charged aza[5]helicene and two charged aza[4]helicenes. Moreover, the bottom-up organic synthesis strategy is further extended to the construction of novel nitrogen-boron-nitrogen (NBN)-containing PAHs. Finally, we discuss the synthesis of four-coordinate boron chromophores containing 6,12,18-tris(alkyl amine)-5,11,17-triazatrinaphthylene derivative ligands.1 Introduction2 Nitrogen-Doped PAHs Based on Dibenzo-9a-azaphenalene (DBAP)3 Cationic Nitrogen-Doped Helical PAHs4 Nitrogen–Boron–Nitrogen-Doped PAHs5 Conclusion and Outlook

Abstract:
Poly(dimethylsiloxane) silicones have found many applications in biomedical devices, whereas their surface hydrophobicity always brings about unexpected bioadhesion, causing complications of the implanted biomedical devices. In this work, surface-initiated reversible addition-fragmentation chain transfer (SI-RAFT) polymerization was utilized to generate PEG brushes on silicone surface, obtaining highly hydrophilic surface coatings. Such PEG brush coated silicone presents excellent antifouling to protein, cells, and bacteria, which may have great potential in implantable biomaterial surface modifications.

Abstract:
ABSTRACTIt is widely claimed that there was a clear spatial continuity in the evolution of the traditional Middle Eastern city, with every new development the result of an intelligent, albeit unplanned, evolution of pre-existing doctrines of construction. However, as far as the new Safavid urban development of seventeenth-century Isfahan (in Iran) is concerned, it is possible to distinguish a spatial fragmentation, in terms of urban pattern and urban structure, between the old texture and new extensions.
