Proof. There are three cases: (1) A and B are in the same column. Then, since in each column we picked the shortest student, A is shorter than B. (2) A and B are in the same row. Then, since in each row we picked the tallest student, B is taller than A. (3) A and B are neither in the same row, nor in the same column. Let C be a student who is in the same row as A and in the same column as B. Th...

An objection to the memetic approach to culture Memetics is one possible evolutionary approach to the study of culture. Boyd and Richerson's models (1985, Boyd this volume), or my epidemiology of representations (1985, 1996), are among other possible evolutionary approaches inspired in various ways by Darwin. The memetic approach is based on the claim that culture is made of memes. If one takes...

Neuroimaging studies have identified two major large-scale brain networks, the default mode network (DMN) and the dorsal attention network (DAN), which are engaged for internally and externally directed cognitive tasks respectively, and which show anticorrelated activity during cognitively demanding tests and at rest. We identified these brain networks using independent component analysis (ICA)...

Many scientists have until recently considered consciousness to be unsuitable for scientific research. As Damasio remarks, ‘studying consciousness was simply not the thing to do before you made tenure, and even after you did it was looked upon with suspicion’ (Damasio, 1999, p. 7). Prompted by technological developments as well as conceptual changes, this attitude has changed within the last de...

Because abnormalities in cerebrovascular reactivity (CVR) in subjects with long-term diabetes could partly be ascribed to autonomic neuropathy and related to central chemosensitivity, CVR and the respiratory drive output during progressive hypercapnia were studied in 15 diabetic patients without (DAN-) and 30 with autonomic neuropathy (DAN+), of whom 15 had postural hypotension (PH) (DAN+PH+) a...

Differential screening-selected gene aberrative in neuroblastoma (DAN) is a member of a cystine knot protein family that includes Cerberus and Gremlin. First isolated in a screen to identify genes down-regulated in transformed rat fibroblasts, DAN has subsequently been cloned in Xenopus, mouse, and human. Overexpression of DAN suppresses the transformed phenotype and retards the cell's entry in...

The Dan family of transforming growth factor beta antagonists is a large, evolutionarily conserved family of proteins. Little is known about either the specificity of these antagonists or the biological roles of these proteins. We have characterized Dan, the founding member of this family, with regard to both its biochemical specificity and its biological roles. Although DAN is not an efficient...

To assess the occurrence and nature of sleep-disordered breathing (SDB) in 26 adult, nonobese diabetics (18 with autonomic neuropathy (DAN+) (age 45 (41-50) yrs; body mass index (BMI) 24.1 (22-26) kg x m(-2)) and eight without autonomic neuropathy (DAN-) (age 45 (35-55) yrs; BMI 24.8 (23-26) kg x m(-2))) overnight full sleep studies and measurements of central and peripheral carbon dioxide (CO2...

Seiring kemajuan dalam teknologi ponsel, Smartphone memiliki kemampuan untuk mengakses layanan web dalam aplikasi pengguna berinteraksi untuk mengambil dan mengirim informasi dari dan ke layanan web. Karenanya, Smartphone semakin meningkat popularitasnya. Pemanfaatan layanan web baru dan layanan web yang telah ada juga akan tumbuh pesat. Makalah ini memberikan perbandingan dari dua jenis utama ...

Supramolecular induction of chirality to a π-stacked dialkoxynaphthalene (DAN)-fiber (made of achiral building blocks) from a neighbouring helical naphthalenediimide (NDI)-fiber is reported. CD-studies helped in understanding the nature of co-assembly in the donor-acceptor chromophore mixture from molecular to macroscopic scale.
