OBJECTIVE The purpose of this investigation was to study the relationship between vertical skeletal growth pattern and dental maturation in children with long or short anterior facial height. MATERIALS AND METHODS The sample consisted of the records of 312 Dutch children (153 boys and 159 girls, aged 9-12.9 years, with a mean chronological age of 11.3 years). The subjects were selected accord...

Seabirds are often studied at individual colonies, but the confounding effects of emigration and mortality processes in open populations may lead to inappropriate conclusions on the mechanisms underlying population changes. Magellanic penguin (Spheniscus magellanicus) colonies of variable population sizes are distributed along the Argentine coastline. In recent decades, several population and d...

A considerable number of growth studies on prematurely born children have been carried out since 1919 when Ylppo (1920) published the first major report on this subject (Capper, 1928; Hess, Mohr and Bartelme, 1934: von Sydow, 1936; Illingworth, 1939; Brander, 1941; Levine and Gordon, 1942; Asher, 1946; Drillien, 1948; Alm, 1953; Douglas and Mogford, 1953). The earlier results are unreliable and...

(ISHRAT HUSAIN) Most of the attention on Islamic finance has so far been focused on the regulatory framework, products and services offered, comparability with conventional finance, risk management characteristics, Shariah compliance, and expansion and penetration issues. Very little work has been done to explore the unique features of Islamic finance for the larger good of the society particul...

We study the role of nano-scale cues in controlling neuronal growth. We use photolithography to fabricate substrates with repeatable line-pattern ridges of nano-scale heights. We find that neuronal processes, which are of micron size, have strong interactions with ridges even as low as 10 nm. The interaction between the neuronal process and the ridge leads to a deflection of growth direction an...

Heat capacities measured as a function of temperature for Al(115)(+), Al(116)(+), and Al(117)(+) show two well-resolved peaks, at around 450 and 600 K. After being annealed to 523 K (a temperature between the two peaks) or to 773 K (well above both peaks), the high temperature peak remains unchanged but the low temperature peak disappears. After considering the possible explanations, the low te...

We investigate multitarget search on complex networks and derive an exact expression for the mean random cover time that quantifies the expected time a walker needs to visit multiple targets. Based on this, we recover and extend some interesting results of multitarget search on networks. Specifically, we observe the logarithmic increase of the global mean random cover time with the target numbe...

As a typical self-driven many-particle system far from equilibrium, traffic flow exhibits diverse fascinating non-equilibrium phenomena, most of which are closely related to traffic flow stability and specifically the growth/dissipation pattern of disturbances. However, the traffic theories have been controversial due to a lack of precise traffic data. We have studied traffic flow from a new pe...

The characteristic growth pattern of fungal mycelia as an interconnected network has a major impact on how cellular events operating on a micron scale affect colony behavior at an ecological scale. Network structure is intimately linked to flows of resources across the network that in turn modify the network architecture itself. This complex interplay shapes the incredibly plastic behavior of f...

According to United Nations estimates, the population of the elderly 60 years and over in the world will reach 1.2 billion by the year 2025, the majority of whom will be in developing countries l . A major factor in the ageing of a population is fertility decline and statistics indicate that f~rtility for Malaysian females has been declinini,3. The implementation of development and health progr...
