Rationalism in Greek Philosophy

Originally published in 1961. Greek philosophers were concerned with the distinction between appearance and reality, and all the differences in their philosophic systems were ultimately predicated on their different views of this distinction. The history of Greek rationalism is, then, a study of the changing basis of Greek philosophy. George Boas provides a historical account of rationalism in classical philosophy. He focuses on four central topics: the distinction between appearance and reality, the method used to establish the distinction, the appraisal of life made by the philosophers studied, and their ethical theories

Studies in Intellectual History

Originally published in 1953. In this collection of essays, prominent midcentury intellectual historians provide critical essays on their field of specialty. This volume gathers work by Harold Cherniss, George Boas, Ludwig Edelstein, Leo Spitzer, and others

Vox Populi

Originally published in 1969. The proverb vox populi, vox Dei first appeared in a work by Alcuin (ca. 798), who wrote that "the people [] are to be led, not followed. [] Nor are those to be listened to who are accustomed to say, 'The voice of the people is the voice of God.'" Tracing the changing meaning of the saying through European history, George Boas finds that "the people" are not an easily identifiable group. For many centuries the butt of jokes and the substance of comic relief in serious drama, the people became in time an object of pity and, later, of aesthetic appeal. Popular opinion, despised in ancient Rome, was something sought, after the French Revolution. The first essay documents the use of the titular proverb through the eighteenth century. In the next six essays, Boas attempts to determine who the people were and how writers and philosophers have regarded them throughout history. He also examines the people as the creators of literature, art, and music, and as the subject of others' artistic representations. In a final essay, he discusses egalitarianism, which has given a voice to the common person. Animating Boas's account is his own belief in the importance of the individual's voice—as opposed to the voice of the masses, which is by no means necessarily that of God or reason

Diffuse Optical Tomography Activation in the Somatosensory Cortex: Specific Activation by Painful vs. Non-Painful Thermal Stimuli

Background: Pain is difficult to assess due to the subjective nature of self-reporting. The lack of objective measures of pain has hampered the development of new treatments as well as the evaluation of current ones. Functional MRI studies of pain have begun to delineate potential brain response signatures that could be used as objective read-outs of pain. Using Diffuse Optical Tomography (DOT), we have shown in the past a distinct DOT signal over the somatosensory cortex to a noxious heat stimulus that could be distinguished from the signal elicited by innocuous mechanical stimuli. Here we further our findings by studying the response to thermal innocuous and noxious stimuli. Methodology/Principal Findings: Innocuous and noxious thermal stimuli were applied to the skin of the face of the first division (ophthalmic) of the trigeminal nerve in healthy volunteers (N = 6). Stimuli temperatures were adjusted for each subject to evoke warm (equivalent to a 3/10) and painful hot (7/10) sensations in a verbal rating scale (0/10 = no/max pain). A set of 26 stimuli (5 sec each) was applied for each temperature with inter-stimulus intervals varied between 8 and 15 sec using a Peltier thermode. A DOT system was used to capture cortical responses on both sides of the head over the primary somatosensory cortical region (S1). For the innocuous stimuli, group results indicated mainly activation on the contralateral side with a weak ipsilateral response. For the noxious stimuli, bilateral activation was observed with comparable amplitudes on both sides. Furthermore, noxious stimuli produced a temporal biphasic response while innocuous stimuli produced a monophasic response. Conclusions/Significance: These results are in accordance with fMRI and our other DOT studies of innocuous mechanical and noxious heat stimuli. The data indicate the differentiation of DOT cortical responses for pain vs. innocuous stimuli that may be useful in assessing objectively acute pain

A high performance cost-effective digital complex correlator for an X-band polarimetry survey

The detailed knowledge of the Milky Way radio emission is important to characterize galactic foregrounds masking extragalactic and cosmological signals. The update of the global sky models describing radio emissions over a very large spectral band requires high sensitivity experiments capable of observing large sky areas with long integration times. Here, we present the design of a new 10 GHz (X-band) polarimeter digital back-end to map the polarization components of the galactic synchrotron radiation field of the Northern Hemisphere sky. The design follows the digital processing trends in radio astronomy and implements a large bandwidth (1 GHz) digital complex cross-correlator to extract the Stokes parameters of the incoming synchrotron radiation field. The hardware constraints cover the implemented VLSI hardware description language code and the preliminary results. The implementation is based on the simultaneous digitized acquisition of the Cartesian components of the two linear receiver polarization channels. The design strategy involves a double data rate acquisition of the ADC interleaved parallel bus, and field programmable gate array device programming at the register transfer mode. The digital core of the back-end is capable of processing 32 Gbps and is built around an Altera field programmable gate array clocked at 250 MHz, 1 GSps analog to digital converters and a clock generator. The control of the field programmable gate array internal signal delays and a convenient use of its phase locked loops provide the timing requirements to achieve the target bandwidths and sensitivity. This solution is convenient for radio astronomy experiments requiring large bandwidth, high functionality, high volume availability and low cost. Of particular interest, this correlator was developed for the Galactic Emission Mapping project and is suitable for large sky area polarization continuum surveys. The solutions may also be adapted to be used at signal processing subsystem levels for large projects like the square kilometer array testbeds
