Acoustic cavitation is investigated experimentally and theoretically starting with a single bubble in an acoustic field. The single bubble is trapped in an acoustic resonator and observed by high-speed imaging and acoustic measurements following its transient dynamics to a possible steady state after generation by laser light. Numerical calculations are done to explore the regions of survival f...

Because loop-like constructs appear in programming languages so often, we need to take fixed points. In addition, because we are defining meaning functions inductively, most or all of the definitions for individual expression forms need to produce continuous functions. Therefore, we need to find an easy way to show that functions are continuous. We will define a restricted language so that all ...

The synthesis of C2-symmetrical bis(β-enamino-pyran-2,4-dione) derivative 3 connected via 1,6-hexylene linker was reported for the first time. X-ray structures and Hirshfeld studies new bis- β-enamino-pyran-2,4-dione along with two structurally related pyran-2,4-dione derivatives 2a,b were discussed. A comparative analysis different intermolecular contacts affecting crystal stability presented....

The proliferation of malware in recent years has motivated the need for tools to detect, analyze, and understand intrusions. Though analysis and detection can be difficult, malware fortunately leaves artifacts of its presence on disk. In this paper, we present Dione, a flexible policy-based disk I/O monitoring and analysis infrastructure that can be used to analyze and understand malware behavi...

The one-pot synthesis of three dragmacidin derivatives is reported. Sarcosine anhydride (4) is brominated and immediately reacted with the corresponding indole to produce the products, namely 3,6-bis(5'-methoxy-3'-indolyl)-1,4-dimethylpiperazine-2,5-dione (1), 3,6-bis(7'-methyl-3'-indolyl)-1,4-dimethylpiperazine-2,5-dione (2) and 3,6-bis-(6'-chloro-3'-indolyl)-1,4-dimethylpiperazine-2,5-dione (...

Three new abietane-type diterpenoids, 7a-butoxyabieta-8,12-diene-11,14-dione (1), 6a,7a-dihydroxyabieta-8,12-dien-11,14-dione (2), and 6a,7b-dihydroxyabieta8,12-diene-11,14-dione (3) were isolated from the bark of Cryptomeria japonica D. Don. Their structures were established by means of 1D and 2D NMR, IR, UV, and HR-EI-MS spectra and comparison with the data of known analogues. ã 2016 Publishe...

In order to know the contribution of adrenal and gonadal androgens to the development of the side gland of Suncus murinus, we studied the effects of gonadectomy and adrenalectomy on gland thickness and the plasma levels of testosterone, androstenedione (delta 4-dione) and dehydroepiandrosterone (DHA). In males, castration decreased gland thickness to 71% of the control. The plasma levels of del...

Several steroids occurring in the pathway of corticosteroid biosynthesis were investigated for their ability to exert a fast or delayed feedback inhibition of stress-induced release of corticotrophin. Rats were injected subcutaneously with vehicle or a steroid either 10 min (fast feedback) or 4 h (delayed feedback) before they were subjected to stress which consisted of a 2 min exposure to ethe...
