A phase transition between jammed and unjammed states could fluidize and mobilize tumor cells as a group, without requiring them to transform from one cell type to a drastically different one, Friedl said.

KGW news in Portland reports according to local experts they've interviewed, thieves jam things into victim's lock to prevent their key from working and go strip the bike of components while it is left unattended while the owner tries to figure out how to get it unjammed.

The combination of these developments eventually culminated in success. On 13 March 1941 Braham achieved a surprise attack on a Dornier Do 17, knocking out one of its engines before the cannons jammed. His radar operator, Sergeant Ross, eventually unjammed three of the guns. Braham's second burst blew the bomber up at a range of 60 yards and the Beaufighter narrowly avoided colliding with the debris.

Bruce 1969, pp. 51–52. The Snark was fitted with what was, for the time, a very heavy armament for a single-seat fighter. In addition to the normal two synchronised Vickers guns inside the fuselage, it had four Lewis guns mounted under the lower wings, firing outside the propeller disc. These guns were inaccessible to the pilot, and so could not be reloaded or unjammed in flight.

In materials science, fragile matter is a granular material that is jammed solid. Everyday examples include beans getting stuck in a hopper in a whole food shop, or milk powder getting jammed in an upside-down bottle. The term was coined by physicist Michael Cates, who asserts that such circumstances warrant a new class of materials. The jamming thus described can be unjammed by mechanical means, such as tapping or shaking the container, or poking it with a stick.

However, it makes the determination of range difficult or impossible. The TRR solves this problem by providing a separate ranging system on another frequency. By making the signal wide-frequency, the jammer has to likewise broadcast across a similar bandwidth, limiting the energy in any one frequency and allowing the operator to tune the receiver to find an unjammed band. Combining range from the TRR and direction from the TTR provided complete information on the target.

A worker who is working on the robot may be injured because a malfunctioning robot is typically unpredictable. For example, a robotic arm that is part of a car assembly line may experience a jammed motor. A worker who is working to fix the jam may suddenly get hit by the arm the moment it becomes unjammed. Additionally, if a worker is standing in a zone that is overlapping with nearby robotic arms, he or she may get injured by other moving equipment.

Allen remained on the scene until two other officers arrived in response to the distress call. He initially fled in his car but quickly returned, attempting to shoot the officers as he drove past. Several more squad cars arrived in pursuit of Allen, still firing from the windows with the service revolver and a now unjammed carbine. After two collisions with police cruisers and one with a CTA bus, Allen was finally stopped when Officer Lawrence Rapien intentionally steered his cruiser head on into Allen's car.

After she stated she would go to the police as soon as he released her, Lockett walked her into a ravine and had his accomplices help her over a barbed wire fence, where Lockett shot her from a distance of approximately six feet with a 1/4-ounce slug from a sawed-off 12-gauge shotgun. The impact from the slug tore into her chest and shoulder, knocking her to the ground. At that time Lockett's gun jammed. As Nieman lay on the ground moaning in agony, he walked back to their vehicle and using a screw driver unjammed the shotgun.

Video of path of flight At 16:09 (00:09 UTC), the flight crew successfully unjammed the horizontal stabilizer with the primary trim system. However, upon being freed, it quickly moved to an extreme "nose-down" position, forcing the aircraft into an almost vertical nosedive. The plane dropped from about to between in around 80 seconds. Both pilots struggled together to regain control of the aircraft, and only by pulling with 130 to 140 pounds (580 to 620 N) on the controls did the flight crew stop the descent of the aircraft and stabilize the MD-83 at approximately .

Squadrons quickly had special chutes fitted to their bombers to make chaff deployment even easier. Seeing this as a development that made it safer to go on operations, many crews got in as many trips as they could before the Germans found a counter-countermeasure. Würzburg Riese radar. The effect of jamming appears in the left "jagged" half of the circular ring, contrasting with the normal "smooth" (unjammed) display on the right half of the circle, with a real target at the 3 o'clock position – on the jammed left side the real target "blip" would have been indistinguishable from the jamming.

This could not be accomplished with the magnetron, whose output frequency is a function of its physical construction, but this was possible using new high-power klystrons. This possibility was developed under the name "Blue Riband", using twelve klystrons that were randomly mixed together to produce an output signal on two widely separated frequencies. Against this new design, the carcinotron would be forced to spread its signal across the entire 500 MHz bandwidth of the set of klystrons. Even then, if its signal was sweeping too slowly it might only jam one of the two frequencies being used for that pulse, allowing the other to be received unjammed.

In this case, the jamming will be the same frequency as the radar for only a short period, while the rest of the radar pulse is unjammed. AESAs can also be switched to a receive-only mode, and use these powerful jamming signals to track its source, something that required a separate receiver in older platforms. By integrating received signals from the targets' own radar along with a lower rate of data from its own broadcasts, a detection system with a precise RWR like an AESA can generate more data with less energy. Some receive beamforming-capable systems, usually ground-based, may even discard a transmitter entirely.

The initial damage reports included a two- to three-hour estimate of restoring steam power as the extent of the damage had not yet been fully assessed, although that was repaired much more quickly than the initial estimate. Focused on the tactical situation, Drew was unaware that steam had been restored to the port outer turbine, the rudder unjammed and electrical power had been restored to the steering gear at about 02:02 before he decided to abandon ship 45 minutes later. Earlier, the destroyer had stopped to render assistance at 01:54 and Drew had transferred 172 wounded and superfluous crewmen before she had to depart to rejoin the convoy.Osbourne, pp. 81–82, 84, 88–89, 100, 105–106; Waters, p.
