Food-bridging: a new network construction to unveil the principles of cooking
In this manuscript we propose, analyse, and discuss a possible new principle
behind traditional cuisine: the Food-bridging hypothesis and its comparison
with the food-pairing hypothesis using the same dataset and graphical models
employed in the food-pairing study by Ahn et al. [Scientific Reports, 1:196
(2011)].
The Food-bridging hypothesis assumes that if two ingredients do not share a
strong molecular or empirical affinity, they may become affine through a chain
of pairwise affinities. That is, in a graphical model as employed by Ahn et
al., a chain represents a path that joints the two ingredients, the shortest
path represents the strongest pairwise chain of affinities between the two
ingredients.
Food-pairing and Food-bridging are different hypotheses that may describe
possible mechanisms behind the recipes of traditional cuisines. Food-pairing
intensifies flavour by mixing ingredients in a recipe with similar chemical
compounds, and food-bridging smoothes contrast between ingredients. Both
food-pairing and food-bridging are observed in traditional cuisines, as shown
in this work.
We observed four classes of cuisines according to food-pairing and
food-bridging: (1) East Asian cuisines, at one extreme, tend to avoid
food-pairing as well as food-bridging; and (4) Latin American cuisines, at the
other extreme, follow both principles. For the two middle classes: (2)
Southeastern Asian cuisines, avoid food-pairing and follow food-bridging; and
(3) Western cuisines, follow food-pairing and avoid food-bridging
National Science Foundation Advisory Committee for Cyberinfrastructure Task Force on Campus Bridging Final Report
The mission of the National Science Foundation (NSF) Advisory Committee on Cyberinfrastructure (ACCI) is to advise the NSF as a whole on matters related to vision and strategy regarding cyberinfrastructure (CI). In early 2009 the ACCI charged six task forces with making recommendations to the NSF in strategic areas of cyberinfrastructure: Campus Bridging; Cyberlearning and Workforce Development; Data and Visualization; Grand Challenges; High Performance Computing (HPC); and Software for Science and Engineering. Each task force was asked to offer advice on the basis of which the NSF would modify existing programs and create new programs. This document is the final, overall report of the Task Force on Campus Bridging.National Science Foundatio
Relationship between bridging and dimensions of sella turcica with classification of craniofacial skeleton
Purpose: In orthodontics, it is essential to determine the craniofacial skeleton pattern (class I, II, III) for planning treatment. Sella turcica bridging that is seen on lateral cephalometric radiographs is considered as a normal finding. This study aimed to compare sella turcica bridging and its dimensions in patients with various craniofacial patterns. Material and methods: A total of 105 lateral cephalometric radiographs (53 men and 52 women), aged 14-26 years, were randomly and equally assigned to three groups of class I, II, and III, respectively. The length, diameter, and depth of the sella turcica as well as sella turcica bridging were determined on radiographs. The chi-squared test was used for assessing the relationship between sella turcica bridging and craniofacial skeleton classification. ANOVA was used for assessing the relationship between the dimensions of the sella turcica and craniofacial skeleton classification. The Pearson's correlation coefficient was used for assessing the relationship between age and the dimensions of the sella turcica. Results: The sella turcica had a normal shape in 64.76% of patients, whereas 35.33% of patients had sella turcica bridging. In total, 11.42% of patients belonged to class I, 34.28% to class II, and 66.62% to class III. The diameter of the sella turcica had a significant relationship with age; the diameter of the sella turcica increased with age (p < 0.001). Conclusions: There is a significant relationship between craniofacial skeleton patterns and sella turcica bridging, i.e., the incidence of sella turcica bridging is higher in class III patients. The sella turcica had a greater diameter in older patients
Bridging transitions for spheres and cylinders
We study bridging transitions between spherically and cylindrically shaped
particles (colloids) of radius separated by a distance that are
dissolved in a bulk fluid (solvent). Using macroscopics, microscopic density
functional theory and finite-size scaling theory we study the location and
order of the bridging transition and also the stability of the liquid bridges
which determines spinodal lines. The location of the bridging transitions is
similar for cylinders and spheres, so that for example, at bulk coexistence the
distance at which a transition between bridged and unbridged
configurations occurs, is proportional to the colloid radius . However all
other aspects, and, in particular, the stability of liquid bridges, are very
different in the two systems. Thus, for cylinders the bridging transition is
typically strongly first-order, while for spheres it may be first-order,
critical or rounded as determined by a critical radius . The influence of
thick wetting films and fluctuation effects beyond mean-field are also
discussed in depth
Structure of adsorbed organometallic rhodium: model single atom catalysts
We have determined the structure of a complex rhodium carbonyl chloride [Rh(CO)(2)Cl] molecule adsorbed on the TiO2 (110) surface by the normal incidence x-ray standing wave technique. The data show that the technique is applicable to reducible oxide systems and that the dominant adsorbed species is undissociated with Rh binding atop bridging oxygen and to the Cl found close to the fivefold coordinated Ti ions in the surface. A minority geminal dicarboryl species, where Rh-Cl bond scission has occurred, is found bridging the bridging oxygen ions forming a high-symmetry site
Bridging the Gap
School districts across the country are increasingly seeking out digital tools to support the work of educators, in the hopes of improving students' academic achievement. With the rapid emergence of this new market, many districts have been challenged by the task of identifying and procuring educational technology (ed-tech) products that match the needs of their educators and students.The NYC Department of Education's "Innovate NYC Schools" division, supported by a U.S. DOE Investing in Innovation (i3) grant, aims to address this problem, in part by promoting "user-centered design," an approach that puts the needs and preferences of products' intended users (in this case, teachers, students, and parents) front and center in the development and procurement of new technology.Bridging the Gap describes the design and implementation of three Innovate NYC Schools initiatives grounded in user-centered design theory:School Choice Design Challenge (SCDC),an effort to develop apps that would help students explore and narrow down their choices of high school.#SharkTankEDU events, during which ed-tech developers present a product to a panel of educators who provide feedback on the tool.Short-Cycle Evaluation Challenges (SCEC), a classroom-based, semester-long pilot of ed-tech tools intended to inform product development, as well as the ultimate procurement decisions of school staff.The report focuses on four phases of work involved in bringing ed-tech companies and the users of their products together: defining a problem; selecting users and ed-tech companies; implementing pilot-based initiatives; and evaluating products. It describes strategies used and challenges faced, and offers practical lessons gleaned from the experiences of the individuals who designed and participated in these efforts.
