Protective effects of hexane fraction of Costus afer leaves against sodium arsenite-induced hepatotoxicity and nephrotoxicity in male albino wistar rats [PDF]
The Ukrainian Biochemical Journal, 2020 Arsenite is a toxic metallic pollutant known to cause hepatotoxic and nephrotoxic injuries. Costus afer Ker Gawl. is an indigenous medicinal plant used as therapy for numerous tissue disorders. Thus, this study investigated the protective potential of C.

SNR Walls for Signal Detection [PDF]
IEEE Journal of Selected Topics in Signal Processing, 2008 This paper considers the detection of the presence/absence of signals in uncertain low SNR environments. Small modeling uncertainties are unavoidable in any practical system and so robustness to them is a fundamental performance metric. The impact of these modeling uncertainties can be quantified by the position of the "SNR wall" below which a detector

The Morphologies of SNRs and their ISM and CSM [PDF]
Symposium - International Astronomical Union, 1998 Recently, many unusual morphologies of supernova remnants (SNRs) have been discovered: semicircular shell; center-brightened but without center point source; two-lobed; bipolar; irregular, etc. To understand these varieties of morphologies, we have made theoretical models.

The Kinematics of The SNR G292.0+1.8 [PDF]
Symposium - International Astronomical Union, 1983 Optical velocity field mapping of G292.0+1.8 in the [0III] λ5007 å line has been carried out using the IPCS with the 3.6 m ESO telescope at La Silla. Our data are not consistent with the suggestion that the [0III] emitting material in the western portion of this remnant is concentrated in an expanding ring. The existing data on G292.0+1.8 suggests that

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments
FEBS Open Bio, EarlyView.Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...
