Gels, such as polyacrylamide gels, are provided that include linear polyacrylamide in the stacking gel. Due to \u201cpost-sense coupling\u201d effects upon activation of the sense amplifiers in conjunction with capacitive coupling effects between bit lines, potential changes occur on adjacent bit lines. The information processing method and apparatus provided by the embodiments of the present disclosure may be used for achieving a failure diagnosis of the user equipment. By combining electrophilic gas injection and bent nose shaping, the system reduces andor eliminates plasma induced communication disruption, such as, GPS communication blackout, for a reentry vehicle during reentry.
