Working and Episodic Memory in HIV Infection, Alcoholism, and Their Comorbidity: Baseline and 1-Year Follow-Up Examinations
Selective memory deficits occur in individuals with human immunodeficiency virus (HIV) infection and those with chronic alcoholism, but the potential compounded effect of these conditions is seldom considered, despite the high prevalence of alcohol use disorders in HIV infection.

Zebrafish Chemical Screening Reveals an Inhibitor of Dusp6 That Expands Cardiac Cell Lineages
The dual-specificity phosphatase 6 (Dusp6) functions as a feedback regulator of fibroblast growth factor (FGF) signaling to limit the activity of extracellular signal–regulated kinases (ERKs) 1 and 2.

Coordinating Asynchronous and Open Distributed Systems Under Semiring-Based Timing Constraints
We focus on coordinating actors and roles through message manipulations based on event-based timing constraints. In addition, different types of timing constraints are generalized into a semiring-based constraint structure; and the all-pairs extremal paths algorithm on closed semirings is applied to derive the most stringent constraints which are logical implications of the original set of…

Calculating Protoplanet Collisions in the Early Solar System
We study shock-synthesized high-pressure phases in meteorites in infer the conditions under which they formed. These phase are found in or adjacent to locally melted veins or pockets that formed on shock compression.

Cellular and Genetic Mechanisms Involved in the Generation of Protective and Pathogenic Immune Responses in Human Chagas Disease
Perhaps one of the most intriguing aspects of human Chagas disease is the complex network of events that underlie the generation of protective versus pathogenic immune responses during the chronic phase of the disease.

Generative and discriminative methods using morphological information for sentence segmentation of Turkish
This paper presents novel methods for generative, discriminative, and hybrid sequence classification for segmentation of Turkish word sequences into sentences.

Mesomechanical Modeling of Fracture
Advanced finite element techniques in simulation of the materials behavior under mechanical loading are reviewed.

Temperature Dependent Nonlinear Absorption in InSb
Temperature dependent two-photon and free-carrier absorption spectra of InSb are measured using femtosecond, picosecond, and nanosecond IR sources. Measurements over this substantial range of pulsewidths give results consistent with a recent theoretical model.

Recommended Resources For The National Defense Education Program Pre-Engineering Partnerships
This SRI International (SRI) report presents the selection criteria applied in selecting five resources for recommendation to PEP. Accompanying narrative scenarios illustrate how the resources can support S&Es who work in middle school classrooms.

Challenges in Scalable Fault Tolerance
Efficient and effective means are needed that exploit structure inherent in one layer of architecture to provide key properties to enable reliable execution at other levels.

Dopamine and Opioid Gene Variants Are Associated with Increased Smoking Reward and Reinforcement Owing to Negative Mood
We explored associations of gene variants in the dopamine, opioid, and serotonin pathways with smoking reward (‘liking’) and reinforcement (latency to first puff and total puffs) as a function of negative mood and expected versus actual nicotine content of the cigarette.

Interleukin 17 Production Among Patients with American Cutaneous Leishmaniasis
We show that lymphocytes obtained from patients with mucosal leishmaniasis and cutaneous leishmaniasis produce higher levels of IL‐17 than do lymphocytes obtained from uninfected control subjects (P
