Headaches are a frequent presenting complaint in the Emergency Department (ED), making up approximately 3.2% of visits annually. Emergency medicine physicians must be adept at differentiating the benign headache from the life-threatening headache associated with critical secondary causes such as an intracranial hemorrhage, mass, or infection. Most headaches are self-limited and arise from prima...

When looking for new and faster parallel sorting algorithms for use in massively parallel systems it is tempting to investigate promising alterna tives from the large body of research done on parallel sorting in the eld of theoretical com puter science Such theoretical algorithms are mainly described for the PRAM Parallel RandomAccess Machine model of computation This paper shows how this kind ...

I Individuals face a self-control problem when the attainment of their overriding long-term interests comes at the expense of short-term but influential outcomes. For example, the boredom that is often associated with studying long hours is a price students have to pay in order to attain academic success, and the discomfort that is often associated with diering or undergoing a medical checkup i...

Briefly and informally an (economic or adaptive) plan can be described in terms of its action with respect to two sets: Cfc, an effectively defined set of objects; M, a set of functions /*#: (P-*(R, £ £ 8 , where (P is the set of distributions over G, and (R is a ranking set of positive real numbers. Under the intended interpretation, each P £ ( P corresponds to a mix of goods, chromosomes, str...

The "original antigenic sin" phenomenon (OAS) 1 challenges the dogma of the specificity of the immunological memory: when there is sequential infection with two different but antigenically related strains of influenza A virus, the antibody stimulated by the second infection reacts more strongly with the primary virus than with the one actually eliciting the response (1-3). This phenomenon is no...

public have developed an increasing appetite for felf-help, alternative medicine, and allergy. This has ?een associated with the development outside the National Health Service of self-referral laboratories and Vanous allergy, ecology and environmental therapy clinics. Patients with chronic, intractable or incurable diseases are a vulnerable group, and anecdotal media rePorts of unlikely and un...

Mountain regions have been identi fied as especially vulnerable areas to climate change. Changes in snowfall, glacier retreat and shifts in biodiversity amount and distribution are some examples of the sensitivity of mountain ecosystems. Moreover, in many mountain economies, reliable snow cover plays a key role as an important resource for the winter tourism industry, the main income source and...

There is always a tradeoff between privacy and the desired level of security for any internet user in the contemporary cyber world. Cyber security, of late, is paramount and its breach could lead to untoward consequences, at times, disastrous. The advent of the IPv6 provides a hope to resolve this tradeoff satisfactorily. Included in the IPV6 suite is a method for devices to automatically confi...

A 10-year-old female patient, being treated for dystrophic bullous epidermolysis in a Pediatric Hospital, was referred to our Dermoscopy Ambulatory because of a newly observed mole in the submandibular area. Clinically, the lesion presented as an irregular double-colored macule of about 2 cm in diameter, with irregular borders, suspicious of malignancy. Dermoscopy showed a multicomponent patter...

This paper presents the LIA summarization systems participating to DUC 2007. This is the second participation of the LIA at DUC and we will discuss our systems in both main and update tasks. The system proposed for the main task is the combination of seven different sentence selection systems. The fusion of the system outputs is made with a weighted graph where the cost functions integrate the ...
