Psychotherapy is predominantly a sedentary practice that, with rare exceptions, does not involve much physical activity on the part of either the client or the therapist. In response to this situation, the article examines three concerns: the impact of sedentarism on psychotherapists; the disconnection between the evidence of the benefit of physical exercise on psychological wellbeing and the predominant focus in psychotherapy on the sedentary mind; and the implications of the disconnection between psychotherapists' own minds and bodies. of the method employed was an heuristic enquiry conducted by the first author (reflected in the "I" and the "my" voice in the article), under the supervision of the second author. Drawing on and interweaving relevant literature throughout, the enquiry explores the first author's own relationship with exercise and, specifically, boxing, as both a practice (i.e., physical exercise) and as a metaphor for the heuristic research process (a psychological and intellectual exercise).

Dual-energy computed tomography (CT) is to reconstruct images of an object from two projection datasets generated from two distinct x-ray source energy spectra. It can provide more accurate attenuation quantification than conventional CT with a single x-ray energy spectrum. In the diagnostic energy range, x-ray energy-dependent attenuation can be approximated as a linear combination of photoelectric absorption and Compton scattering. Hence, two physical components of x-ray attenuation can be determined from two spectral informative projection datasets to achieve monochromatic imaging and material decomposition. In this paper, a projection decomposition method is proposed for the image reconstruction in dual-energy CT. This method combines both an analytical algorithm and a single-variable optimization method to solve the non-linear polychromatic x-ray integral model, allowing accurate quantification of photoelectric absorption and Compton scattering components. Numerical tests are performed to illustrate the merit of the proposed method by comparing with classical projection decomposition methods.

Abstract—Dual-energy computed tomography (CT) is to reconstruct images of an object from two projection datasets generated from two distinct x-ray source energy spectra. It can provide more accurate attenuation quantification than conventional CT with a single x-ray energy spectrum. In the diagnostic energy range, x-ray energy-dependent attenuation can be approximated as a linear combination of photoelectric absorption and Compton scattering. Hence, two physical components of x-ray attenuation can be determined from two spectrally informative projection datasets to achieve monochromatic imaging and material decomposition. In this paper, a projection-domain image reconstruction method is proposed to accurately quantify the two attenuation components for dual-energy CT. This method combines both an analytical algorithm and a single-variable optimization method to solve the non-linear polychromatic x-ray integral model, allowing an efficient and accurate decomposition of physical basis components. Numerical tests are performed to illustrate the merit of the proposed method.

In medical X-ray Computed Tomography (CT), the use of two distinct X-ray source spectra (energies) allows dose-reduction and material discrimination relative to that achieved with only one source spectrum. Existing dual-energy CT methods include source kVp-switching, double-layer detection, dual-source gantry, and two-pass scanning. Each method suffers either from strong spectral correlation or patient-motion artifacts. To simultaneously address these problems, we propose to improve CT data acquisition with the Grating Oriented Line-wise Filtration (GOLF) method, a novel X-ray filter that is placed between the source and patient. GOLF uses a combination of absorption and filtering gratings that are moved relative to each other and in synchronization with the X-ray tube kVp-switching process and/or the detector view-sampling process. Simulation results show that GOLF can improve the spectral performance of kVp-switching to match that of dual-source CT while avoiding patient motion artifacts and dual imaging chains. Although significant flux is absorbed by this pre-patient filter, the proposed GOLF method is a novel path for cost-effectively extracting dual-energy or multi-energy data and reducing radiation dose with or without kVp switching.

Allen Forte produced an immense body of work in music theory—ten books, sixty-three articles, and thirty-six other publications.1 Over the course of his forty-year academic career, he supervised seventy-two Ph.D. students and encouraged many more. And he was a founder and first President of the Society for Music Theory. His extraordinary dedication to this field—setting it up as the academic specialty it now is in the American academy—is a monumental contribution to its institutional history. David Lewin may have capsuled it best in his dual dedication of Musical Form and Transformation to Forte and Milton Babbitt: “For Milton, who showed me the world of music theory, and Allen, who showed me how to live there.”2 How did Allen Forte make a place for us to live in such a world? Two banquet addresses tell the story. The first was given at the tenth-year anniversary of SMT in 1987, in Rochester; and the second at the twenty-fifth, 2002, in Columbus. I was present at both occasions, and was pleased that these addresses were eventually published in near-original form.3 They are noteworthy documents of oral history. They also show a side of Forte that tremulous graduate students did not see, a charming raconteur who gave his naturally dry wit a wider range and much broader smile; I came to know this side well in Forte's later years, and came also to appreciate the serious, determined, and single-minded music theorist who could channel these impulses with a sophisticated charisma that inspired people with his vision, whether they agreed with its details or not.

Abstract This article presents a three-section discussion, exploring the specific interrelated themes and questions central to the transformational and neo-Riemannian enterprise. The first section discusses the natures of musical objects and relations within the transformational worldview. It asks what happens when tones and chords are imagines not as objects but as transformations. The second section delves further into the object/transformation dichotomy. It explores the structural and functional differences among dissonant and consonant trichords in a particular nonatonic cycle. It also explores how the voice-leading functional and set-theoretical implications of the cycle might be engaged by a transformational perspective as a means to impart “sensuous distinctions”. The last section examines the analytical implications of the first two sections, by examining Vaughan Williams's neo-modal triadic Fantasia on a Theme by Thomas Tallis.
