Some writers have suggested that they may have evolved as a visual signal of sexual maturity and fertility.

Some audio formats feature a combination of a lossy format and a lossless correction which when combined reproduce the original signal ; the correction can be stripped, leaving a smaller, lossily compressed, file.

Some pulse modulation schemes also allow the narrowband analog signal to be transferred as a digital signal ( i. e. as a quantized discrete-time signal ) with a fixed bit rate, which can be transferred over an underlying digital transmission system, for example some line code.

Some neurons do not generate action potentials, but instead generate a graded electrical signal, which in turn causes graded neurotransmitter release.

Some proteins, such as insulin, are extracellular proteins that transmit a signal from the cell in which they were synthesized to other cells in distant tissues.

Some types of phospholipid can be split to produce products that function as second messengers in signal transduction.

Some transmitters are capable of direct frequency-shift keying ( FSK ) as they can directly accept the digital signal and change their transmitting frequency according to the mark or space input state.

Some articles published before 1977 used the term signal transmission or sensory transduction for signal transduction: a total of 48, 377 scientific papers related to signal transduction were published in 1977, of which 11, 211 were reviews of other papers.

Some local farming communities that were not connected to the main networks set up barbed wire telephone lines that exploited the existing system of field fences to transmit the signal.

Some cardiac cells are self-excitable, contracting without any signal from the nervous system, even if removed from the heart and placed in culture.

Some measurements in signal circuits require higher sensitivity movements so as not to load the circuit under test with the meter impedance.

Some computer systems, upon receiving a boot signal from a human operator or a peripheral device, may load a very small number of fixed instructions into memory at a specific location, initialize at least one CPU, and then point the CPU to the instructions and start their execution.

Some object at the remote location echoes this PN signal back to the location station – either passively, as in some kinds of radar and sonar systems, or using an active transponder at the remote location, as in the Apollo Unified S-Band system.

Some applications have the receiver tied to other equipment that uses the audio muting control voltage as a " signal present " indication.

Some of the signal power may be reflected back to its origin rather than being carried all the way along the cable to the far end.

Some time before she had ordered the signal beacons set up for just such a purpose.

Some active subwoofers use a servo feedback mechanism based on cone movement which modifies the signal sent to the voice coil.

Some transmission systems contain multipliers, which amplify a signal prior to re-transmission, or regenerators, which attempt to reconstruct and re-shape the coded message before re-transmission.

Some communities make use of an " all clear " signal, or sound separate signals for fire calls and ambulance runs.

Some early VCRs would record audio without a control track signal, but this was of little practical use since the absence of a control track signal meant that the linear tape speed was irregular during playback.

Some of the other impairments reported were decreased IQ, visiomotor coordination, information processing, verbal learning and concentration.

Some of the earliest examples of this technology implemented input / output processing such as direct memory access as a separate thread from the computation thread.

Some of these technologies include speech recognition software to allow computers to handle first level of customer support, text mining and natural language processing to allow better customer handling, agent training by automatic mining of best practices from past interactions, support automation and many other technologies to improve agent productivity and customer satisfaction.

Some of Simon's economic research was directed toward understanding technological change in general and the information processing revolution in particular.

Some kinds of changes are a part of the everyday routine of information processing and adhere to a predefined procedure, which reduces the overall level of risk to the processing environment.

Some philosophers divide consciousness into phenomenal consciousness, which is subjective experience itself, and access consciousness, which refers to the global availability of information to processing systems in the brain.

Some scientific journals have begun to set detailed standards for what types of image processing are allowed in research results.

Some psychologists propose that this processing gives rise to particular mental states ( cognitivism ) whilst others envisage a direct path back into the external world in the form of action ( radical behaviourism ).

Some examples are VLIW, MISC, OISC, massive parallel processing, systolic array, reconfigurable computing, and dataflow architecture.

Some of these molecules like NOD2 interact with RIP2 kinase that activates NF-κB signaling, whereas others like NALP3 interact with inflammatory caspases and initiate processing of particular cytokines like interleukin-1β.

Some automated reasoners exploit the graph-theoretic features of the networks during processing.

Some intrinsics were provided to accelerate string processing ( e. g. scanning in an array for a particular search pattern ); other language extensions were provided to allow the UCSD p-System to be self-compiling and self-hosted.

Some vodkas are made from potatoes, molasses, soybeans, grapes, rice, sugar beets and sometimes even byproducts of oil refining or wood pulp processing.

* Some models of sub-controllers ( usually lower cost ) have no memory and processing power to make access decisions independently.

Some governments are tolerant and accepting of onshore asylum claims ; other governments arrest or detain those who attempt to seek asylum ; sometimes while processing their claims.

Some high compression algorithms require high processing power.

Some modelling and escort agencies will tell applicants that they have a number of clients lined up, but that they require a " registration fee " of sorts to account for processing and marketing expenses, or so it is claimed, which is paid in a number of untraceable methods, most often by cash ; once the fee is paid, the applicant is informed that the client has cancelled, and thereafter they never contact the applicant again.

The magical number seven, plus or minus two: Some limits on our capacity for processing information.

Some of these buildings contain facilities for processing and storing olive oil, such as Maroni-Vournes and Building X at Kalavassos-Ayios Dhimitrios.

Some methods of compensating for this or otherwise producing much wider digital photographs involve using a fisheye lens and " defishing " the image in post processing to simulate a rectilinear wide angle lens.

Some systems also include permute functions that re-pack elements inside vectors, making them particularly useful for data processing and compression.

Some sausages are cooked during processing and the casing may be removed after.

Some techniques which are used in digital image processing include:

Some lower-budget recordings from the 1970s and 1980s have a " lo-fi " sound due to the limitations of the analog recording and processing techniques, which introduced unwanted artifacts such as distortion and phase problems.
