Dithienylethene molecular switch.

However, examination of viral resistance to AD101, molecular antagonist of CCR5, indicated that resistant viruses did not switch to another coreceptor ( CXCR4 ) but persisted in using CCR5, either through binding to alternative domains of CCR5, or by binding to the receptor at a higher affinity.

* A molecular switch is a molecule that can be reversibly shifted between two or more stable states.

The rotational barrier for a push-pull olefin is lower than that of an ordinary olefin and this makes it an interesting candidate for a molecular switch for instance azobenzenes.

The molecular component can be described as a molecular switch, and may perform this function by any of several mechanisms, including charge storage, photochromism, or changes in capacitance.

An evolutionary capacitor is a molecular switch mechanism that can " toggle " genetic variation between hidden and revealed states.

Dimeric α-catenin preferentially binds to actin and suppresses Arp2 / 3 complex-mediated actin branching, thus acting as a molecular switch to regulate actin polymerization.

The assignment of actual addresses to symbolic index word and electronic switch names occurs in Phase 3, of the Autocoder processor.

The initial setting of the availability table indicated that the index word or electronic switch was not available for assignment.

The one- or two-digit number of the index word or electronic switch was used in the operand of a symbolic machine instruction to specify indexing or as a parameter which is always an index word or electronic switch, e.g., 3.

The one- or two-digit number of the index word or electronic switch was used in the operand of an EQU statement, e.g.,

any such reference will make the index word or electronic switch unavailable at the end of this pass.

During the assignment pass, each instruction is examined for reference to the symbolic name of an index word or electronic switch.

If the one- or two-digit address of an index word or electronic switch is used or is included in the operand of an XRESERVE or SRESERVE statement ( see page 99 ), the corresponding index word or electronic switch is reserved.

Extreme caution should be used, however, to avoid the conflicting usage of an index word or electronic switch which may result from the assignment of more than one name or function to the same address.

If the symbolic name or actual address of an index word or electronic switch appears or is included in the operand of an XRELEASE or SRELEASE statement ( see page 101 ), the specified index word or electronic switch will again be made available, regardless of the method by which it was reserved.

Each switch occupies one digit position in a word, can be set on or off, and is considered as logically equivalent to an electronic switch.

It cannot, however, be referred to by electronic switch commands, e.g., ESN, BSN, etc..

Guitar amplifiers and electronic keyboards may have switch pedals for turning built-in effects on and off.

The advantages of optical keyboard technology are that it offers a real waterproof keyboard, resilient to dust and liquids ; and it uses about 20 % PCB volume, compared with membrane or dome switch keyboards, significantly reducing electronic waste.

Subsequently, in 1974, the same workers at the Physics Department of The University of Texas M. D. Anderson Cancer Center reported an organic electronic device, a voltage-controlled switch.

* Solid state relay, an electronic switch built of solid materials

When the current through the device is reversed, the electrodes switch functions, so anode becomes cathode, while cathode becomes anode, as long as the reversed current is applied, with the exception of diodes where electrode naming is always based on the forward current direction.

Whilst this had the advantage of being usable by untrained users via ' hunt and peck ' typing and requiring one less key switch than a conventional 12 button keypad, it had the disadvantage that some symbols required three times as much force to depress them as others which made it hard to achieve any speed with the device.

Among the obstacles are demonic monsters, pits of toxic or radioactive slime, ceilings that lower and crush the player, and locked doors for which a keycard, skull-shaped key device, or remote switch must be located.

The input signal is used to switch the active device causing pulses of current to flow through a tuned circuit forming part of the load.

* 1891 – Almon Strowger, an undertaker in Topeka, Kansas, patents the Strowger switch, a device which led to the automation of telephone circuit switching.

* Node ( networking ), a device such as a computer or switch attached to a computer or telecommunications network, or a point in a network topology where lines intersect

Other characters do not use the swazzle, so the Punchman had to switch back and forth while still holding the device in his mouth.

A solid-state relay uses a thyristor or other solid-state switching device, activated by the control signal, to switch the controlled load, instead of a solenoid.

* Isolate the controlling circuit from the controlled circuit when the two are at different potentials, for example when controlling a mains-powered device from a low-voltage switch.

The most familiar form of switch is a manually operated electromechanical device with one or more sets of electrical contacts, which are connected to external circuits.

Another view is that a device which is plugged into an electrical outlet of a wall becomes part of the building, but is nonfunctional while the switch is off ; turning it on would then constitute " building " and turning it off would be " demolishing " ( categories 35 and 34 ).

The landline telephone contains a switchhook ( A4 ) and an alerting device, usually a ringer ( A7 ), that remains connected to the phone line whenever the phone is " on hook " ( i. e. the switch ( A4 ) is open ), and other components which are connected when the phone is " off hook ".

A transistor is a semiconductor device used to amplify and switch electronic signals and electrical power.

The device being the " Soft " power switch, the NIC ( via Wake-on-LAN ), the cover being opened, a temperature change, etc.

Additionally, a device which can switch the machine off and on again, controlled perhaps by a remote signal, can force a reboot which will clear problems due to misbehaving software.

The Frame Relay network exists between a LAN border device, usually a router, and the carrier switch.

Digital techniques are useful because it is easier to get an electronic device to switch into one of a number of known states than to accurately reproduce a continuous range of values.

To switch off an n-channel device requires a negative gate-source voltage ( V < sub > GS </ sub >).

Conversely, to switch off a p-channel device requires V < sub > GS </ sub > positive.

Avaya ERS 3500 and ERS 2500 series | ERS 2550T-PWR 50-port network switch A network switch or switching hub is a computer networking device that connects network segments or network devices.

A switch is a telecommunication device which receives a message from any device connected to it and then transmits the message only to the device for which the message was meant.
