OBJECTIVE To analyze the long-term changes in maxillary arch widths and buccal corridor ratios in orthodontic patients treated with and without premolar extractions. METHODS The study included 53 patients who were divided into the extraction (n = 28) and nonextraction (n = 25) groups. These patients had complete orthodontic records from the pretreatment (T1), posttreatment (T2), and postreten...

Fundamental characteristics of decentralized separation control in a high density air corridor are discussed. A high density air corridor is expected to be an air space where aircraft capable of airborne self-separation are allowed to fly into the same direction. Some decentralized control algorithms are indispensable for its operational safety and a large traffic throughput. In this study two ...

Non-coding sequence in eukaryotes encodes functionally important signals for the regulation of gene expression. Since these elements are evolutionary conserved among related taxa due to stabilizing selection they accumulate less mutations than adjacent non-functional DNA. These conserved non-coding sequences with potential regulatory activity, are known as phylogenetic footprints. They can be d...

In response to growing awareness of climate change, requests to establish product carbon footprints have been increasing. Product carbon footprints are life cycle assessments restricted to just one impact category, global warming. Product carbon footprint studies generate life cycle inventory results, listing the environmental emissions of greenhouse gases from a product's lifecycle, and charac...

Strict control of tissue-specific gene expression plays a pivotal role during lineage commitment. The transcription factor c-Myb has an essential role in adult haematopoiesis and functions as an oncogene when rearranged in human cancers. Here we have exploited digital genomic footprinting analysis to obtain a global picture of c-Myb occupancy in the genome of six different haematopoietic cell-t...

background and objectives: in the last few decades, losses of our cultural heritage due to biodeteriorationare beinghighly recognized. from museum objects to rock monuments, the microbial biodeterioration agents are found to be the most destructive. possibilities for proper preservative measure(s) are always more when it is only a monument, statue, museum article, or pre-historic art in any sma...

This article found that Characteristic behavior from footprints as appeared in the Aṭṭhakathā-Dhammapada: way to look at characteristic behaviors know personality of a person appears scriptures commentary class. It mentions those with Rāga-carita have concave centered-footprints, Dosa-carita squeeze heel or heavy heels; Moha-carita peaked front footprints; center ridge caress unclear footprints...

This study deals with the influence landmark information has on the foraging behaviour of the desert ant, Cataglyphis fortis, especially with the interaction of such landmark information with the ants' path integration system. We show in the first experiment that desert ants that are captured immediately after leaving their nest and then transferred to a remote test area search for the nest rat...

Flow corridor is a new class of trajectory-based airspace which derives from the Next Generation Air Transportation System Concept of Operations. Reducing the airspace complexity and increasing the capacity are the main purpose of the en-route corridor. This paper analyzes the collision risk-capacity tradeoff using combined discrete-continuous simulation method. A basic two-dimensional en-route...

n Flight delays are now a major problem in the U.S. National Airspace System. A significant fraction of these delays are caused by reductions in en route capacity due to severe convective weather. The Corridor Integrated Weather System (CIWS) is a fully automated weather analysis and forecasting system designed to support the development and execution of convective weather impact mitigation pla...
