When will they (ever) learn?
… that networks affect learning, there is little direct evidence linking social networks to learning. And opposing network features are often emphasized. While some scholars have emphasized the importance of closed networks, others have highlighted networks that span structural holes, a network …

Aedes Albopictus in Peoria, an Invasion by an Exotic Mosquito Vector Into an Urban La Crosse Virus Endemic Area in Illinois
Although no direct evidence was found that Ae. albopictus is serving as a vector for La Crosse virus encephalitis, LAC virus continues to circulate in the sciurid amplifier host population and Ae. albopictus was shown to utilize sciurid bloodmeals. Continued surveillance is recommended to monitor …

Historical fire regimes in southeasern pine savannas
Southeastern coastal plain pine savannas lack direct evidence of past fire regimes. As a result, uncertainty exists regarding the range of variation in frequency and seasonal timing of past fire regimes and the relative importance of anthropogenic and lightning-ignited fires. Characterization of …

Functional Correlates of Exposure to Complex, Spatial Environments in Rat Dentate Gyrus
… neurophysiological studies have provided strong evidence for a hippocampal role in learning and memory, but there is little direct evidence for experience-related synaptic alterations within the hippocampus. In these experiments, synaptic transmission was evaluated in the dentate gyrus of …

Rearrangements of 1-Heterosubstituted Chrysanthemyl Aldehyde and Chrysanthemyl Amines
… analog of presqualene pyrophosphate. There is no direct evidence for this discrete new intermediate but a successful synthesis of it would facilitate, via biosynthetic incorporation studies, determination of whether or not such an intermediate does exist. With this goal in mind, research was …

The effect of antiretroviral treatment on HIV associated tuberculosis incidence and outcomes in the Free State Province, South Africa.
… mortality in the region, there is little direct evidence of the magnitude of its effect on mortality in people coinfected with TB, or on TB treatment outcomes. There is little evidence on the effect of ART on TB incidence in HIV positive people in South Africa, which has most HIV-TB cases …

Characterization of the Active Site of Chloroperoxidase Using Physical Techniques (Hemeproteins)
… of my research has been devoted to obtaining direct evidence that CPO also has a thiolate 5th ligand from a cysteine residue. This information will provide the framework for a detailed analysis of the structure-function relationships between peroxidases, catalase and cytochrome P-450 …

The Mechanism of the Action of Gastrin on Guinea Pig Ileum Smooth Muscle
… the gastrointestinal tract. Vizi et al. produced direct evidence that gastrin caused the release of acetylcholine from Auerbach's plexus of guinea pig terminal ileum which, in turn, caused the muscle to contract. The purpose of this study was to verify the findings of Vizi et al. and to describe …

Telomere Specific Homologous Recombination in the Alternative Lengthening of Telomeres
… mechanism remain a mystery. A growing body of evidence suggests that ALT cells maintain telomeres by homologous recombination (Reddel 2003 for Review). Groundbreaking work by Oliver Bechter demonstrated that ALT cells and telomerase-positive cells show no difference in the rate of general HR. …

FACILITATING CLINICAL DECISION-MAKING IN REHABILITATION: INNOVATIVE APPROACHES TO SYNTHESIZE AND TRANSLATE EVIDENCE INTO PRACTICE
Integrating scientific evidence into clinical rehabilitation practice is essential to ensuring effective, data-driven interventions. However, translating this evidence into everyday clinical decision-making presents significant challenges due to the complexity of available information and the need …

Single-crystal metal oxides and supported metal nanoclusters as model catalyst sytems
… Ultraviolet photoelectron spectroscopy shows direct evidence of charge transfer from high-temperature adsorbed phenol to electronic states of TiO2(110) usually associated with the accumulation of charge at surface oxygen vacancies, providing direct evidence of a frequently-hypothesized radical …

Prediction-driven computational auditory scene analysis
… cannot 'infer' the presence of a sound for which direct evidence is hidden by other components. The 'prediction-driven' approach is presented as an alternative, in which analysis is a process of reconciliation between the observed acoustic features and the predictions of an internal model of the …

The Human Dentate Gyrus Plays A Necessary Role in Discriminating New Memories
… pictures. These results provide the first direct evidence in humans that discriminating new memories cannot wholly function without an intact dentate gyrus and that this mnemonic ability is dissociable from, but likely interacts with, completion processes in the CA3 subfield of the …

TREX1 AUTOIMMUNE DISEASE MUTANTS REVEAL DIMERIC STRUCTURE REQUIREMENTS AND THE C-TERMINAL REGION OF TREX1 CONTROLS CELL LOCALIZATION THROUGH UBIQUITINATION
… the activity of the opposing protomer provides direct evidence that TREX1 activity is dependent on a dimeric structure, and suggests a possible mechanism for modulating TREX1 acitivity in a cell by disrupting dimer contacts.

Essays on nominal rigidities, bounded rationality, and macroeconomic policy
… lie at the core of macroeconomics. The empirical evidence suggests that prices and wages adjust sluggishly to aggregate shocks, while theoretical models justify why and to what extent these rigidities imply monetary non-neutrality. However, direct evidence on nominal rigidities being the actual …

Real-time mass spectrometric analysis of catalytic reaction mechanisms
… of equilibria were observed, and there is no direct evidence of a single pathway. Instead, there appear to be two mechanisms which are active in different conditions (one fluoride, one aqueous). Studies were initiated into the related SM polycondensation reaction and the hydrolysis of …

The Long Non-coding RNA Malat1 Regulates Inflammatory Cytokine Production in Chronic Diabetic Complications
… SAA3 and p53. The data from this study provided direct evidence to the importance of MALAT1 in the pathogenesis of chronic diabetic complications involving the heart and kidneys.
