Novel molecular architectures from iptycene polymers
… were targeted because they possess a unique structural property called internal molecular free volume. When these bulky pendant groups are incorporated into the backbone of a polymer chain, they produce a novel chain architecture called molecular barbed wire. This molecular barbed wire …

Controllability and Observability of a Large Scale Thermodynamical System via Connectability Approach
… condition are investigated through the structural property of a digraph called connectability. It will be shown that the connectability condition between input and states, as well as output and states of a nonlinear system are equivalent to Lie-algebra rank condition. This approach has …

Combinatorial channels from partially ordered sets
… systems. Our goal is to identify and exploit structural properties common to a wide variety of coding problems, classical and modern, using the framework of partially ordered sets. We represent adversarial error models as combinatorial channels, form combinatorial channels from posets, …

Database optimization algorithm for empirical potentials
… technique to estimate the errors for the structural property functions in the testing set. We provide the first analytical derivations of how modifications in the fitting database affect the testing set errors. A new binary modified embedded-atom method functional form is developed for …

The diphthongs of Spanish: Stress, syllabification, and alternations
… stress, rather than in terms of a feature, or a structural property of high vowels. Such a proposal reduces the inventory of Spanish syllable types and allows us to eliminate the feature (syllabic). The Sonority Principle and the two-mora limit per syllable determine syllabic wellformedness. This …

Machine learning for strength prediction and optimal design of sustainable concrete formulas
… mixes with low carbon footprints that still meet structural performance requirements will be an essential part of global decarbonization efforts. In this work, we build a concrete performance model, which maps from concrete constituents to compressive strength, a key structural property. …

Understanding the Role of Ligand Oxidation State: Design, Synthesis, and Reactivity of Electronically Asymmetric Molybdenum Dithiolene Complexes
… oxo-MoIV(dithiolene) complexes exhibit a unique structural property, a large fold angle along the S•••S vector of the dithione ligand. These complexes also show a positive solvatochromic effect in a range of polar to nonpolar solvents. The rich electrochemical properties of these redox active …

An Assessment of Impediments to Low-Impact Development in the Virginia Portion of the Chesapeake Bay Watershed
… the implementation of LID: site-specific & non-structural, property owner acceptance, pollutant removal benefit, development rules, lack of education, maintenance considerations, flooding problems, and cost. Lack of education was ranked as the most important impediment, with development rules …

The Cover Time of Random Walks on Graph
… We also show that with high probability, a structural property of the graph called conductance, is bounded below by a constant. This is of independent interest. Finally, we explore random walks with weighted random edge choices. We present a weighting scheme that has a smaller worst case …

Bone Properties of Recombinant Inbred Line - BXD Mouse
… on characterizing genetic-influence based bone structural response.</p> <p>51 BXD RI mouse strains were analyzed, including progenitor C57BL/6J (n=16) and DBA/2J (n=15), and two first filial generations (D2B6F1 and B6D2F1). Bones were collected from 10 to 14-week old females and males (N≥3 each …

Licensing Of Cell Fate Reprogramming Via Leafy Transcription Factor Pioneering Activity
… of LFY and wondered whether its unique structural property, a long central disordered domain in between two multivalent functional domains, could support the formation of membrane-less compartments in cells and offer an additional layer of regulation through phase separation. By …

Structural Properties of Genotype-Phenotype Maps: Models, Estimates and Evolution
… studies a range of questions surrounding the structural properties of GP maps. In the first part, the origin of a striking structural property shared by GP maps is studied, namely the positive correlation between the robustness and evolvability of phenotypes. By introducing analytically …

Symmetries in algebraic Property Testing
… only inspecting a small window into the data. In Property Testing, a local algorithm should perform the task of distinguishing objects satisfying a given property from objects that require many modifications in order to satisfy the property. A special place in Property Testing is held by algebraic …

Vulnerability analysis of electricity distribution networks with large-penetrations of PEVs and DERs
… optimal attack strategy exhibits an interesting structural property: the downstream nodes are more critical for limiting costs of reactive power supply and maintaining voltage regulation. This insight is useful for vulnerability assessment of DNs under DER/PEV node compromises. Finally, we also …

Investigating the sink efficiencies of interfaces under irradiation
… building block to understand many classical structural-property relationships in polycrystals. Interfaces serve as sinks, sources or trap sites for vacancies, which facilitate creep, can drive interface migration, or serve as a vacancy-interstitial recombination site that results in an ideal …

Progressive Collapse Assessment of Steel and Concrete Composite Structures Subjected to Extreme Loading Conditions
… discussed inside the scientific community. The structural property associated with such a vulnerability is named robustness. Depending on the type of the structural system and on the importance of consequences, specific design strategies can be adopted in order to ensure a robust structural …
