Problems hampering

Siberian stone pine (Pinus sibirica Du Tour) is a cone-bearing species with outstanding nutritious seeds, health-supporting properties, and nut oil. Currently, the main volume of pine nuts is harvested in natural forests, which causes damage to ecosystems. The best solution to this problem would be harvesting nuts on special pine nut plantations established on the basis of high-seeding clones. However, it is hampered by the low efficiency of the existing methods for assessing plus-tree productivity.

Sustainability challenges are currently hampering an increase in salmon production. Using sterile salmon can solve problems with precocious puberty and genetic introgression from farmed escapees to wild populations. Recently sterile salmon was produced by knocking out the germ cell-specific dead end (dnd).

Identification of cis- and trans-acting factors regulating gene expression remains an important problem in biology. Bioinformatics analyses of regulatory regions are hampered by several difficulties. One is that binding sites for regulatory proteins are often not significantly over-represented in the set of DNA sequences of interest, because of high levels of false positive predictions, and because of positional restrictions on functional binding sites with regard to the transcription start site.

Accurate gene regulatory networks can be used to explain the emergence of different phenotypes, disease mechanisms, and other biological functions. Many methods have been proposed to infer networks from gene expression data but have been hampered by problems such as low sample size, inaccurate constraints, and incomplete characterizations of regulatory dynamics.

Twenty years after the discovery of neural stem cells, the question whether the central nervous system can be considered among regenerative tissues is still open. On one side, deep characterization of neural stem and progenitor cells, their niches, and their progeny in brain neurogenic sites overtly showed that new neurons can be generated in the brain of adult mammals, including humans.

Statistical parsing of noun phrase (NP) structure has been hampered by a lack of goldstandard data. This is a significant problem for CCGbank, where binary branching NP derivations are often incorrect, a result of the automatic conversion from the Penn Treebank.(N (N/N lung) (N (N/N cancer) (N deaths) ) )This structure is correct for most English NPs and is the best solution that doesn’t require manual reannotation. However, the resulting derivations often contain errors.

Despite the rising interest in developing grammatical error detection systems for non-native speakers of English, progress in the field has been hampered by a lack of informative metrics and an inability to directly compare the performance of systems developed by different researchers. In this paper we address these problems by presenting two evaluation methodologies, both based on a novel use of crowdsourcing.

One of the major challenges facing statistical machine translation is how to model differences in word order between languages. Although a great deal of research has focussed on this problem, progress is hampered by the lack of reliable metrics. Most current metrics are based on matching lexical items in the translation and the reference, and their ability to measure the quality of word order has not been demonstrated.

Managing inter-object dependencies in object-oriented systems is a complex task. Changes of one object often require dependent objects to change accordingly. Making every object explicitly inform every dependent object about its state changes intertwines object interfaces and implementations, thereby hampering system evolution and maintenance. These problems can be overcome by introducing the notion of Implicit Invocation to object-oriented systems as a decoupling mechanism between objects.

As companies refocus their attention on growth, many find they are held back by the very thing that should be propelling them forward: their sales force. For too many organizations, this critical function is hampered by ineffective sales people and with the expensive drag of turnover. It’s a problem that has held the attention of executives for many years—but one that also has gone largely unsolved.

Since the dawn of history, human activities have always been closely related to friction, the resistance to sliding. It is thanks to friction that one can stand and walk on the ground, one can wear clothes, one can make fire by rubbing two sticks together, or one can even start and stop a car. In these cases friction is very useful for human beings. In many other cases, however, human activities have been very much hampered by friction since ancient times. How to diminish friction is one of the most basic technological problems. For example, when a heavy...

Solve Two of the Toughest Problems When Preparing for the Stockbroker’s Exam Those wishing to become licensed as stockbrokers must pass the series 7 examination. This exam, known officially as the General Securities Registered Representative Examination, is very rigorous. Traditionally, students without a financial background have a difficult time with the mathematical calculations peculiar to the world of stocks, bonds, and options. Many are also relatively unfa- miliar with proper use of the calculator and thus are dou- bly hampered in their efforts to become registered.
