Background We wish to introduce a new chemical format called UCM (Universal Chemical Markup). The format is based on XML (Extensible Markup Language) and its first version focuses on recording chemical structures and their properties. Results UCM currently supports structures containing isotopes, ions and various types of bonding including delocalized bonds. Properties can be expressed by combi...

Scenario-driven requirement specifications are widely used to capture and represent functional requirement. More recently, the Use Case Maps language (UCM), being standardized by ITU-T as part of the User Requirements Notation (URN) has gained on popularity within the software requirements community. UCM models focus on the description of functional and behavioral requirements as well as high-l...

BACKGROUND Umbilical cord milking (UCM) improves blood pressure and urine output, and decreases the need for transfusions in comparison to immediate cord clamping (ICC). The immediate effect of UCM in the first few minutes of life and the impact on neonatal resuscitation has not been described. METHODS Women admitted to a tertiary care center and delivering before 32 weeks gestation were rand...

Uremic cardiomyopathy (UCM) is characterized by metabolic remodelling, compromised energetics, and loss of insulin-mediated cardioprotection, which result in unsustainable adaptations and heart failure. However, the role of mitochondria and the susceptibility of mitochondrial permeability transition pore (mPTP) formation in ischemia-reperfusion injury (IRI) in UCM are unknown. Using a rat model...

—We describe and demonstrate the Unit Characteristic Method (UCM) as a means by which measurements of habitat from typical stream surveys can be used to estimate the capacity of a stream to rear juvenile steelhead Oncorhynchus mykiss. Channel unit features of importance include surface area by unit type, depth, substrate, and cover. The influence of a stream’s primary productivity is represente...

The way to ensure that students will learn informatics (computer science) concepts is focused on learner's intrinsical motivation. Informatics concepts based on tasks and puzzles raise students' interest. Teachers need diverse activities that can lead students to deeper understanding. Algorithms are very important part of informatics. Thus we need to introduce various algorithms even at school....

Early during neuromuscular development, acetylcholine receptors (AChRs) accumulate at the center of muscle fibers, precisely where motor growth cones navigate and synapses eventually form. Here, we show that Wnt11r binds to the zebrafish unplugged/MuSK ectodomain to organize this central muscle zone. In the absence of such a zone, prepatterned AChRs fail to aggregate and, as visualized by live-...

Twitter (and similar microblogging services) has become a central nexus for discussion of the topics of the day. Twitter data contains rich content and structured information on users’ topics of interest and behavior patterns. Correctly analyzing and modeling Twitter data enables the prediction of the user behavior and preference in a variety of practical applications, such as tweet recommendat...

This paper presents the results of a study to determine if and how the use case model (UCM) could be used by strategists in small businesses. The reason for wanting to use the UCM in this way is to get problem domain experts, that is top management, more involved in systems development by creating a requirements model which can be used by systems developers as a starting point for analysis. The...

Immune rejection of transplanted material is a potential complication of organ donation. In response to tissue transplantation, immune rejection has two components: a host defense directed against the grafted tissue and an immune response from the grafted tissue against the host (graft vs host disease). To treat immune rejection, transplant recipients are typically put on immunosuppression ther...
