Financial support for Clean Development Mechanism (CDM) projects in underrepresented host countries was agreed on at the Copenhagen conference. The EU rules include special import quotas for Certified Emission Reductions (CERs) from Least Developed Countries (LDCs). This paper discusses whether these measures can contribute to overcoming barriers to CDM development in LDCs, how Programmes of Ac...

BACKGROUND The Observational Medical Outcomes Partnership (OMOP) Common Data Model (CDM) has been implemented on various claims and electronic health record (EHR) databases, but has not been applied to a hospital transactional database. This study addresses the implementation of the OMOP CDM on the U.S. Premier Hospital database. METHODS We designed and implemented an extract, transform, load...

مقدمه: یکی از عوامل دخیل در ایجاد بیماری آلزایمر تجمع پپتیدهای آمیلوئید بتا و تشکیل پلاک های آمیلوئیدی در مغز می باشد. کاهش میزان این پلاک ها سبب بهبود بیماری آلزایمر می شود. عوامل مختلفی از جمله فاگوسیتوز توسط سلول های سیستم ایمنی، آنزیم های پروتئولیتیک و کبد در پاک سازی مغز از پلاک های آمیلوئیدی نقش دارند. در مطالعات قبلی نشان دادیم که عصاره آبی اسطوخدوس سبب بهبود حافظه موش های صحرایی آلزایمر...

I present a specific worked example of evolution through inflation to the initial conditions for an isocurvature CDM model for structure formation. The model invokes three scalar fields, one that drives power law inflation, one that survives to become the present-day CDM, and one that gives the CDM field a mass that slowly decreases during inflation and so “tilts” the primeval mass fluctuation ...

With the imminent promise of constraints on the epoch of reionization from observations of microwave background anisotropies, the question of whether or not the standard Cold Dark Matter (CDM) model permits early reionization has been subjected to detailed investigation by various authors, with the conclusion that reionization may occur at quite high redshift. However, it is widely accepted tha...

Cold Dark Matter (CDM) models of galaxy formation had been remarkably successful to explain a number of observations in the past decade. However, with both the theoretical modeling and the observations being improved, CDM models have been very recently shown to have excessive clustering on the sub-galactic scale. Here I discuss a solution, based on our high-resolution numerical simulations, to ...

Humans can learn concepts or recognize items from just a handful of examples, while machines require many more samples to perform the same task. In this paper, we build a computational model to investigate the possibility of this kind of rapid learning. The proposed method aims to improve the learning task of input from sensory memory by leveraging the information retrieved from long-term memor...

In the standard cold dark matter (CDM) theory of cosmic structure formation, CDM particles are assumed to be collisionless. The actual identity and microscopic nature of CDM is still unknown, however. It is important, therefore, to explore the consequences of varying this underlying assumption about CDM in the hope that astronomical observations can be used to place meaningful constraints. It h...

As the 2012 end of the first commitment period of the Kyoto Protocol is fast approaching, there is a strong realisation that the Clean Development Mechanism (CDM) projects have no doubt been playing an important role globally, particularly in promoting clean development in China. Consequently, the prospects for the CDM market in the post-Kyoto era are attracting a lot of attention, including fr...

Over almost all of minimal supergravity (mSUGRA or CMSSM) model parameter space, there is a large overabundance of neutralino cold dark matter (CDM). We find that the regions of mSUGRA parameter space which match the measured abundance of CDM in the universe are highly fine-tuned, unless tanβ is very large. If instead we invoke the Peccei-Quinn-Weinberg-Wilczek solution to the strong CP problem...
