Nano Delivery Strategy Opens Effective Avenues for the Treatment of Colorectal Cancer

open access: yesMedicine Bulletin, Volume 2, Issue 2, Page 205-230, March 2026.
ABSTRACT Colorectal cancer (CRC) presents significant therapeutic challenges because of chemoresistance, systemic toxicity, and the complexity of the tumor microenvironment (TME). Nanodrug delivery systems (NDDS) have emerged as versatile platforms capable of overcoming these limitations by enhancing tumor accumulation, improving pharmacokinetics, and ...

Link analyses and LPD/AJ strategies for IEEE 802.16a [PDF]

open access: yes, 2007
In military operations, covertness of operation is of paramount importance. The transmission power of the data link must be kept to the minimum to maintain a low probability of detection (LPD) from the adversary. However, a reduction in the transmitted

Comparison of complementary sequences in hybrid phase and frequency shift keying CW radar using periodic ambiguity analysis [PDF]

open access: yes, 2012
Continuous waveform (CW) polyphase sequences for radar have a much lower power spectral density (PSD) than pulsed signals but can retain the same target detection capability.

Comparative Analysis of High‐Throughput Phenotyping Techniques for Early Detection of Herbicide Stress

open access: yesWeed Research, Volume 66, Issue 2, March/April 2026.
ABSTRACT Early detection of herbicide‐induced stress is essential for optimising weed control, improving crop safety and advancing precision agriculture practices. While non‐destructive imaging technologies offer great potential for rapid stress diagnosis, direct comparisons of their performance across species, herbicides and application rates remain ...
