Ophthalmology was the first medical specialty to adopt lasers right after their invention more than 50 years ago, and they gradually revolutionized ocular imaging, diagnostics, therapy, and surgery. Challenging precision, safety, and selectivity requirements for ocular therapeutic and surgical procedures keep advancing the laser technologies, which in turn continue enabling novel applications f...

This paper examines the death penalty question from the perspective of the new ethical theory, the Principle of Goodness. At first sight, the Principle seems to be a strictly tighter moral principle than Kant’s categorical imperative; yet we find that the application diverges from the recommendations of Kant in this case. Unlike many discussions of this question, which often argue either no, or...

Angular reconstitution in combination with multivariate statistical techniques to classify and average the characteristic views of a molecule form a complete, selfcontained methodology for the high-resolution threedimensional (3D) structure analysis of uncrystallized macromolecules by electron microscopy. The angular reconstitution approach is based on the fact that two different two-dimensiona...

Despite the urgent need to develop professional ethics regarding information behaviour, several obstacles exist in Japan. The greatest is the lack of individuals’ ethics of responsibility. To overcome this difficulty, we must examine and reflect on the historical circumstances that led to the formation of Japanese core ethics and on the sociocultural context that compensates for the lack of ind...

World health organization (WHO) and International agency for the prevention of blindness (IAPB) along with local Governmental and Non-Governmental partners lunched a global initiative for elimination of avoidable blindness in the late 1990s with an aim to eliminate avoidable blindness by the year 2020. World sight day is observed on the second Thursday of October to highlight the plight of peop...

Macaque monkeys were presented with continuous rapid serial visual presentation (RSVP) sequences of unrelated naturalistic images at rates of 14--222 msec/image, while neurons that responded selectively to complex patterns (e.g., faces) were recorded in temporal cortex. Stimulus selectivity was preserved for 65% of these neurons even at surprisingly fast presentation rates (14 msec/image or 72 ...

Perhaps in no field of human disease, more than in the field of rheumatism and connective-tissue disorders, have such great technical advances been made in methods of biological study. Some of the knowledge thus gained and some of the ideas suggested are at present difficult to apply directly to the clinical problems that face rheumatologists. Moreover, some of the newly discovered facts seem a...

We present the historical light curve of T Tau derived from photographic plates in the Harvard College Observatory archives. We find that the optical light of T Tau varied by 2-3 (or more) magnitudes on time scales as short as a month prior to ∼ 1917, consistent with the results of Lozinskii (1949). Extreme light fluctuations of greater than 2 magnitudes abruptly ceased in the late 1910's and, ...
