The Ramsey number is known for only a few specific knots and links, namely the Hopf link and the trefoil knot (although not published in periodicals). We establish the lower bound of all Ramsey numbers of any knot to be one greater than its stick number. 1 Background and Definitions The study of Ramsey numbers of knots can be found at the intersection of knot theory and graph theory. 1.1 Knot T...

OBJECTIVE In this study, we determined the assay performance criteria necessary to produce acceptable results for >or=98% of neonate bilirubin samples collected by capillary heel-stick. STUDY DESIGN AND METHODS We determined serum free hemoglobin levels in 151 heel-stick serum samples to determine the hemolysis level. We then tested the effect of hemolysis on total bilirubin levels determined...

The vision of legendary criminologist Cesare Lombroso to use scientific theories of individual causes of crime as a basis for screening and prevention programmes targeting individuals at risk for future criminal behaviour has resurfaced, following advances in genetics, neuroscience and psychiatric epidemiology. This article analyses this idea and maps its ethical implications from a public heal...

Medical students face the threat of needle stick injury with the consequent risk of acquiring blood-borne infection by pathogens such as HIV, Hepatitis B and Hepatitis C while performing their clinical activities in the hospitals. A cross-sectional study was conducted among 417 final year medical students from Universiti Kebangsaan Malaysia (UKM), University Malaya (UM) and Universiti Putra Mal...

Stick models are widely used in studying the behaviour of straight as well as skew bridges and viaducts subjected to earthquakes while carrying out preliminary studies. The application of such models to highly curved bridges continues to pose challenging problems. A viaduct proposed in the foothills of the Himalayas in Northern India is chosen for the study. It is having 8 simply supported span...

Robustness and reliability is the essence of speech communication. The senses collaborate with memory and other brain mechanisms to decode spoken language in the harsh and often unpredictable environments of the real world. How the brain makes speech “stick” is the focus of this special session, which examines how the senses and motor system coordinate during speech perception and production.

Targeting the inner nuclear membrane roteins destined for the inner nuclear membrane (INM) start out in the peripheral ER. Diffusion from the ER will get them to the contiguous outer nuclear membrane (ONM), but the next step could involve either vesicular transport, short-lived fusions between INM and ONM, or movement along the lipid bilayers surrounding nuclear pores. On page 1051, Ohba et al....

During the past two decades there has been a heated debate about the causes of the German so-called Wirtschaftswunder (economic miracle) after the Second World War. This debate came somewhat unexpectedly, as the German war generation always took it for granted that the impressive growth record in the 1950s and 60s was a consequence of economic liberalization after 15 years of tight planning and...

s Gibson (1982) correctly points out, despite Quine's brief flirtation with a " mitigated phenomenalism " (Gibson's phrase) in the late 1940's and early 1950's, Quine's ontology of 1953 (" On Mental Entities ") and beyond left no room for non-physical sensory objects or qualities. Anyone familiar with the contemporary neo-dualist qualia-freak-fest might wonder why Quinean lessons were insuffici...

We propose a modular, reactive controller for locating a target in a maze while maintaining sufficient battery power. We have adapted our solution of take into account the limitations of the simulation environment and the high level of noise. The behavior of our robot proved to be sensible though being by far less efficient than mappingbased solutions.
