Three words from the sacred harp

This three-movement choral piece was written for the University of Glasgow Madrigirls, which is an all female choir under the direction of Katy Cooper and Catriona Hutchinson. The first movement is for two mezzo soprano soloists, the second movement is for quintet, and the third movement is for the full SSAA choir. The piece takes selections of texts from the Sacred Harp Hymnal which are unified according to three movements by the following three words: 1) "I", 2) "will" and 3) "sing". The following is a program note from the first performance on June 17, 2011. <br></br><br></br> Three Words from the Sacred Harp is constructed around the words “I”, “Will” and “Sing”, which were taken from the Sacred Harp, 1991 Edition. <br></br><br></br> In the first movement, a duet on I, the extracts dwell on ideas of journeying home. <br></br><br></br> Journey Home 111<br></br><br></br> I'm on my journey home<br></br><br></br> Parting Friends 267<br></br><br></br> I'm trav'ling through the wilderness<br></br><br></br> Journey Home 111<br></br><br></br> I'm bound fair Canaan's land to see<br></br><br></br> 80 Service to the Lord<br></br><br></br> Farewell, vain world I'm going home<br></br><br></br> <br></br><br></br> My Savior smiles and bids me come Devotion 48<br></br><br></br> Then shall I see, and hear, and know<br></br><br></br> Journey Home 111<br></br><br></br> Oh, who will come and go with me?<br></br><br></br> I'm Going Home 282 <br></br><br></br> And I don't care to stay here long!<br></br><br></br> Eternal Day 383<br></br><br></br> Rivers of life divine I see. <br></br><br></br> In the second movement, on Will, the words deal with inviting God into the home. <br></br><br></br> 335 Return again<br></br><br></br> All will come to desolation, unless Thou return again.<br></br><br></br> 161 Sweet Home<br></br><br></br> All will be peace when I’m with Thee at home. <br></br><br></br> The third movement, Sing, deals with death and eternity. <br></br><br></br> Infinite delight 562<br></br><br></br> And thus I begin to sing<br></br><br></br> Oh grave, where is thy triumph now?<br></br><br></br> Oh death, where is thy sting?<br></br><br></br> Wooten 548<br></br><br></br> And I soon shall sing in eternity<br></br><br></br> Fillmore 434<br></br><br></br> Thus I will sing, till sense and language are no more<br></br><br></br> <br></br><br></br> Many thanks to the Madrigirls for their wonderful singing, to Creative Scotland for making this project possible, and to fasola.org for providing such a unique way of examining the Sacred Harp

A system-on-chip digital pH meter for use in a wireless diagnostic capsule

This paper describes the design and implementation of a system-on-chip digital pH meter, for use in a wireless capsule application. The system is organized around an 8-bit microcontroller, designed to be functionally identical to the Motorola 6805. The analog subsystem contains a floating-electrode ISFET, which is fully compatible with a commercial CMOS process. On-chip programmable voltage references and multiplexors permit flexibility with the minimum of external connections. The chip is designed in a modular fashion to facilitate verification and component re-use. The single-chip pH meter can be directly connected to a personal computer, and gives a response of 37 bits/pH, within an operating range of 7 pH units

Human immunodeficiency virus treatment-induced adipose tissue pathology and lipoatrophy: Prevalence and metabolic consequences

Lipoatrophy and metabolic complications of treatment of human immunodeficiency virus (HIV) infection may share common associations with adipose tissue pathology and inflammation. To investigate these relationships, we undertook a large-scale study of adipose tissue, body composition, and metabolic outcomes among HIV-infected adult men at a tertiary hospital HIV cohort during the period 2001-2007. Methods. Assessments included adipose biopsies (np211) for investigation of adipocyte mitochondrial DNA content, adipocytokine expression, and adipose macrophage content; and whole-body dual-energy X-ray absorptiometry (DEXA) scans (np225) for objective body composition changes; 138 individuals contributed both biopsy and DEXA data. Results. Compared with 78 treatment-naive control subjects, 98 zidovudine recipients (48%) and 49 stavudine recipients (67%) had leg fat measures <10% threshold value. Adipose samples associated with current stavudine or zidovudine (np99) revealed significant adipocyte mitochondrial DNA depletion, adipose tissue macrophage infiltration, and elevated proinflammatory cytokine levels, compared with samples from control subjects and nonthymidine nucleoside reverse-transcriptase inhibitor (NRTI) recipients (all P<.05). Improvements in adipose pathology after NRTI switching (np21 longitudinal samples) correlated with increased preswitch adipose inflammation and less severe fat loss (both P<.05). Elevated ratios of total to high-density lipoprotein cholesterol levels and Homeostatic Metabolic Assessment scores correlated independently with lipoatrophy severity (P<.05) and increased body mass index (P<.05) in thymidine NRTI-experienced individuals. No effect of demographic or HIV-related variables, or HIV protease inhibitor therapy exposure was detected. Conclusions. Adipose tissue pathology and lipoatrophic fat loss are highly prevalent among recipients of stavudine- or zidovudine-based HIV treatment and are associated with adverse metabolic outcomes. Restoring adipose tissue health appears to be an important issue in the long-term treatment of this patient population

Design of a single-chip pH sensor using a conventional 0.6-&#956;m CMOS process

A pH sensor fabricated on a single chip by an unmodified, commercial 0.6-/spl &#956;m CMOS process is presented. The sensor comprises a circuit for making differential measurements between an ion-sensitive field-effect transistor (ISFET) and a reference FET (REFET). The ISFET has a floating-gate structure and uses the silicon nitride passivation layer as a pH-sensitive insulator. As fabricated, it has a large threshold voltage that is postulated to be caused by a trapped charge on the floating gate. Ultraviolet radiation and bulk-substrate biasing is used to permanently modify the threshold voltage so that the ISFET can be used in a battery-operated circuit. A novel post-processing method using a single layer of photoresist is used to define the sensing areas and to provide robust encapsulation for the chip. The complete circuit, operating from a single 3-V supply, provides an output voltage proportional to pH and can be powered down when not required

Threshold behavior of bosonic two-dimensional few-body systems

Bosonic two-dimensional self-bound clusters consisting of $N$ atoms interacting through additive van der Waals potentials become unbound at a critical mass m*(N); m*(N) has been predicted to be independent of the size of the system. Furthermore, it has been predicted that the ground state energy E(N) of the N-atom system varies exponentially as the atomic mass approaches m*. This paper reports accurate numerical many-body calculations that allow these predictions to be tested. We confirm the existence of a universal critical mass m*, and show that the near-threshold behavior can only be described properly if a previously neglected term is included. We comment on the universality of the energy ratio E(N+1)/E(N) near threshold.Comment: 6 pages, 3 figure

Moment bounds for the Smoluchowski equation and their consequences

We prove uniform bounds on moments X_a = \sum_{m}{m^a f_m(x,t)} of the Smoluchowski coagulation equations with diffusion, valid in any dimension. If the collision propensities \alpha(n,m) of mass n and mass m particles grow more slowly than (n+m)(d(n) + d(m)), and the diffusion rate d(\cdot) is non-increasing and satisfies m^{-b_1} \leq d(m) \leq m^{-b_2} for some b_1 and b_2 satisfying 0 \leq b_2 < b_1 < \infty, then any weak solution satisfies X_a \in L^{\infty}(\mathbb{R}^d \times [0,T]) \cap L^1(\mathbb{R}^d \times [0,T]) for every a \in \mathbb{N} and T \in (0,\infty), (provided that certain moments of the initial data are finite). As a consequence, we infer that these conditions are sufficient to ensure uniqueness of a weak solution and its conservation of mass.Comment: 30 page

The Trapped Polarized Fermi Gas at Unitarity

We consider population-imbalanced two-component Fermi gases under external harmonic confinement interacting through short-range two-body potentials with diverging s-wave scattering length. Using the fixed-node diffusion Monte Carlo method, the energies of the "normal state" are determined as functions of the population-imbalance and the number of particles. The energies of the trapped system follow, to a good approximation, a universal curve even for fairly small systems. A simple parameterization of the universal curve is presented and related to the equation of state of the bulk system.Comment: 4 pages, 2 tables, 2 figure

Effects of Enamel Paint on the Behavior and Survival of the Periodical Cicada, \u3ci\u3eMagicicada Septendecim\u3c/i\u3e (Homoptera) and the Lesser Migratory Grasshopper, \u3ci\u3eMelanoplus Sanguinipes (Orthoptera).

We present information compiled from several studies on the effects of methods for marking individual arthropods on their longevity and behavior. Results from our own research on effects of enamel paint marking on two in- sect species, the periodical cicada, Magicicada septendecim, and the lesser migratory grasshopper, Melanoplus sanguinipes, are also presented. Neither species showed any adverse survivorship or behavioral effects from marking
