چکیده

Abstract Understanding the chemical past of our Sun and how life appeared on Earth is no mean feat. The best strategy we can adopt to study newborn stars located in an environment similar one which was born assess their content. In particular, hot corinos are prime targets because recent studies have shown correlations between interstellar complex organic molecules abundances from comets. ORion ALMA New GEneration Survey aims number closest analog Sun’s birth environment, OMC-2/3 filament. this context, investigated nature 19 solar-mass protostars found that 26% sample sources show warm methanol emission indicative corinos. Compared Perseus low-mass star-forming region, where PErseus CHEmistry detected ∼60% sources, seem be relatively scarce While suggests Orion different, improved statistics needed order consolidate result. If two regions truly would indicate likely playing a role shaping composition protostars.

We define a unit system for end-user spreadsheets that is based on the concrete notion of units instead of the abstract concept of types. Units are derived from header information given by spreadsheets. The unit system contains concepts, such as dependent units, multiple units, and unit generalization, that allow the classification of spreadsheet contents on a more fine-grained level than types...

The most comprehensive and often-cited statistic about the U.S. economy is gross domestic product (GDP), the sum of all goods and services produced in the United States. Estimates of GDP are the featured statistics in the National Income and Product Accounts, the construction of which involves the collection and aggregation of an immense amount of data. In the construction of real GDP, complica...

We investigate the combinatorics of a topological space that is generated by the set of edgeweighted finite trees. This space arises by multiplying the weights of edges on paths in trees and is closely connected to tree reconstruction problems involving finite state Markov processes. We show that this space is a contractible finite CW-complex whose face poset can be described via a partial orde...

Comparing Apples and Oranges – How Reliable are Molecular Docking Tools?

The development a novel drug is a time consuming and expensive process. Besides the identification of the target, a significant amount of time and money is required to screen large libraries of compounds for drug candidates. Computational methods, namely molecular docking techniques, play, thus, an important role in the drug discovery process. Employing these techniques, scientists hope to iden...
