We developed a 12-item, short form of the Experiences in Close Relationship Scale (ECR; Brennan, Clark, & Shaver, 1998) across 6 studies. In Study 1, we examined the reliability and factor structure of the measure. In Studies 2 and 3, we cross-validated the reliability, factor structure, and validity of the short form measure; whereas in Study 4, we examined test-retest reliability over a 1-mon...

Some mAL neurons in the male brain form the ipsilateral neurite (ILN[+]) in a manner dependent on FruBM, a male-specific transcription factor. FruBM represses robo1 transcription, allowing the ILN to form. We found that the proportion of ILN[+]-mALs in all observed single cell clones dropped from ∼90% to ∼30% by changing the heat-shock timing for clone induction from 4-5 days after egg laying (...

Proper assembly and maintenance of epithelia are critical for normal development and homeostasis. Here, using the Drosophila ovary as a model, we identify a role for the B1 isoform of the ecdysone receptor (EcR-B1) in this process. We performed a reverse genetic analysis of EcR-B1 function during oogenesis and demonstrate that silencing of this receptor isoform causes loss of integrity and mult...

The reconstruction of evolutionary trees is a major problem in biology, and many evolutionary trees are estimated using heuristics for the NP-hard optimization problem Maximum Parsimony. The current heuristics for searching through tree space use a particular technique, called “tree-bisection and reconnection”, or TBR, to transform one tree into another tree; other less-frequently used transfor...

Proper coupling of the rf power to the plasma in an electron-cyclotron resonance (ECR) ion source is probably the most important factor in achieving satisfactory performance of overdense plasmas in high-current ECR sources. Poor coupler design can lead to a variety of undesirable effects such as high reflected power, low plasma density, unstable operation, and poor performance. Scientific Solut...

MicroRNA-34 (miR-34) is crucial for preventing chronic large-scale neurite degeneration in the aged brain of Drosophila melanogaster. Here we investigated the role of miR-34 in two other types of large-scale axon degeneration in Drosophila: axotomy-induced axon degeneration in olfactory sensory neurons (OSNs) and developmentally related axon pruning in mushroom body (MB) neurons. Ectopically ov...

The aim of this study was to enhance the understanding of cultural and sample differences in the assessment of attachment by examining the factor structure of the Experiences in Close Relationships-Revised (ECR-R). The ECR-R is a self-report measure of adult romantic attachment dimensions. The present study used a Danish sample with the purpose of addressing limitations in previous studies, suc...

In the absence of cell migration, plant architecture is largely determined by the direction and extent of cell expansion during development. In this report, we show that very-long-chain fatty acid (VLCFA) synthesis plays an essential role in cell expansion. The Arabidopsis thaliana eceriferum10 (cer10) mutants exhibit severe morphological abnormalities and reduced size of aerial organs. These m...

Male-male courtship is infrequent among mature adult Drosophila melanogaster. After pairs of mature adult males expressing a temperature-sensitive allele of the ecdysone receptor (EcR) gene were treated at a restrictive temperature, however, they engaged in elevated levels of male-male courtship. EcR-deficient males courted wildtype males and females, but were not courted by wildtype males. The...
