Chemotherapy extravasation is a potentially serious complication. There is a paucity of information in the veterinary literature investigating extravasation events, treatments, and outcomes. Evaluate chemotherapy extravasation events and treatments in dogs and cats, adverse events (AEs), and overall outcomes. Twenty dogs and three cats were included. Retrospective, multicenter, descriptive study including dogs or cats with suspected extravasation from chemotherapy. Information obtained included: signalment, extravasation details and treatment provided, AEs graded according to VCOG-CTCAE v2 criteria, and outcome. The most common drug extravasated was doxorubicin, followed by carboplatin. Carboplatin extravasation (n = 5) resulted in Grades III-IV AEs, all of which required surgical debridement. Doxorubicin extravasation (n = 9) resulted in Grades 0-V AEs, two of which amputation was ultimately recommended, and one of those two was euthanized instead. Extravasation of vinca alkaloids (n = 5) and rabacfosadine (n = 1) resulted in Grades II-III AEs, all managed in the outpatient setting. Mitoxantrone (n = 2) and dacarbazine (n = 1) extravasation resulted in no clinical signs associated with extravasation injury. Seventy-eight percent (18/23) cases had extravasation occur during one of the first four treatments of chemotherapy, with 30% (7/23) occurring during the first chemotherapy treatment. Most cases (20/23) had mild to moderate or no AEs. Findings support that carboplatin should be considered a vesicant.

The prevalence and correlates of suicidal threats and attempts among 662 racially and ethnically diverse adult female victims of intimate partner violence (IPV) were studied. One in five women had threatened or attempted suicide during her lifetime. They observed that multiple logistic regression results indicated that women at greater risk of severe or potentially lethal assaults as measured by the Danger Assessment and those who reported having a chronic or disabling illness were more likely to have threatened or attempted suicide. A linear association was found between age and suicide threats/attempts, with younger women having increased odds. Finally, African American IPV victims were less likely to have threatened or attempted suicide as compared to Latina victims. Study implications are discussed.

This paper presents new lower and upper bounds for the optimal compression of binary prefix codes in terms of the most probable input symbol, where compression efficiency is determined by the nonlinear codeword length objective of minimizing maximum pointwise redundancy. This objective relates to both universal modeling and Shannon coding, and these bounds are tight throughout the interval. The upper bounds also apply to a related objective, that of d <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">th</sup> exponential redundancy.

Abstract— The investigation of visual‐quality issues for high‐contrast projection screens such as those used for avionics projection displays and other applications requiring a high level of ambient light rejection will be described. Visibility of artifacts and noise generated by the optical and structural properties of a variety of high‐contrast projection screens was characterized by both empirical, subjective image quality evaluations and a suite of objective screen‐quality metrics. At least two of these metrics were found to provide very good correlation with the subjective assessment. These metrics are applicable to any display system where spatial‐noise artifacts are an issue, such as with direct‐view AMLCDs with anti‐glare treatments.

We report on the recent advances made by our groups in the technology and applications of Holographically formed Polymer Dispersed Liquid Crystal (HPDLC) devices. In this paper we will briefly review some of the basic operating principles of HPDLC devices and their salient features as applied to display and image capture applications. The usability of HPDLC films in displays is enhanced by incorporating diffusion into the films. The photopic reflectance and reflection bandwidth of an HPDLC device can be improved by stacking multiple films of HPDLC material between one set of electrodes. HPDLC mirrors can be used to advantage in an electronic image capture system.

Abstract We demonstrate a Holographic‐Polymer Dispersed Liquid Crystal (H‐PDLC) with an enhanced viewing‐angle, formed by writing a diffuse hologram structure directly into our H‐PDLC material. We model the diffuse H‐PDLC reflectance by summing over the contributions of discrete grating domains of differing orientations. We use a normal distribution function to weight each orientation to describe the grating densities. SEM studies were performed to determine the morphologies and orientations of multiple gratings within the sample.
