signals whose levels differ by one decibel have a power ratio of 10110 approximately 126 or rootpower ratio of 101⁄20 approximately 112the unit expresses a relative change or an absolute value in the latter case the numeric value expresses the ratio of a value to a fixed reference value when used in this way the unit symbol is often suffixed with letter codes that indicate the reference value for example for the reference value of 1 volt a common suffix is v eg 20 dbvtwo principal types of scaling of the decibel are in common use when expressing a power ratio it is defined as ten times the logarithm in base 10 that is a change in power by a factor of 10 corresponds to a 10 db change in level when expressing rootpower quantities a change in amplitude by a factor of 10 corresponds to a 20 db change in level the decibel scales differ by a factor of two so that the related power and rootpower levels change by the same value in linear systems where power is proportional to the square of amplitude the definition of the decibel originated in the measurement of transmission loss and power in telephony of the early 20th century in the bell system in the united states the bel was named in honor of alexander graham bell but the bel is seldom used instead the decibel is used for a wide variety of measurements in science and engineering most prominently for sound power in acoustics in electronics and control theory in electronics the gains of amplifiers attenuation of signals and signaltonoise ratios are often expressed in decibels the decibel originates from methods used to quantify signal loss in telegraph and telephone circuits until the mid1920s the unit for loss was miles of standard cable msc 1 msc corresponded to the loss of power over one mile approximately 16 km of standard telephone cable at a frequency of 5000 radians per second 7958 hz and matched closely the smallest attenuation detectable to a listener a standard telephone cable was a cable having uniformly distributed resistance of 88 ohms per loopmile and uniformly distributed shunt capacitance of 0054 microfarads per mile approximately corresponding to 19 gauge wirein 1924 bell telephone

transmission lines such planar transmissionline resonators can be very compact in size and are widely used elements in microwave circuitry in cryogenic solidstate research superconducting transmissionline resonators contribute to solidstate spectroscopy and quantum information science in a laser light is amplified in a cavity resonator that is usually composed of two or more mirrors thus an optical cavity also known as a resonator is a cavity with walls that reflect electromagnetic waves ie light this allows standing wave modes to exist with little loss mechanical resonators are used in electronic circuits to generate signals of a precise frequency for example piezoelectric resonators commonly made from quartz are used as frequency references common designs consist of electrodes attached to a piece of quartz in the shape of a rectangular plate for high frequency applications or in the shape of a tuning fork for low frequency applications the high dimensional stability and low temperature coefficient of quartz helps keeps resonant frequency constant in addition the quartzs piezoelectric property converts the mechanical vibrations into an oscillating voltage which is picked up by the attached electrodes these crystal oscillators are used in quartz clocks and watches to create the clock signal that runs computers and to stabilize the output signal from radio transmitters mechanical resonators can also be used to induce a standing wave in other media for example a multiple degree of freedom system can be created by imposing a base excitation on a cantilever beam in this case the standing wave is imposed on the beam this type of system can be used as a sensor to track changes in frequency or phase of the resonance of the fiber one application is as a measurement device for dimensional metrology the most familiar examples of acoustic resonators are in musical instruments every musical instrument has resonators some generate the sound directly such as the wooden bars in a xylophone the head of a drum the strings in stringed instruments and the pipes in an organ some modify the sound by enhancing particular frequencies such as the sound box of a guitar or violin organ pipes the bodies of woodwinds and the sound boxes of stringed instruments are examples of acoustic cavity resonators the exhaust pipes in automobile exhaust systems are designed as acoustic resonators that work with the muffler to reduce noise by making sound waves cancel each other out the exhaust note is an important feature for some vehicle owners so both the original manufacturers and the aftermarket suppliers use the resonator to enhance the sound in tuned exhaust systems designed for performance the resonance of the exhaust pipes can also be

the only viable superfluid medium that can currently be used is helium4 and it has been successfully accomplished in controlled conditions such solvents are currently under investigation for use in spectroscopic techniques in the field of analytical chemistry due to their superior kinetic properties any matter dissolved or otherwise suspended in the superfluid will tend to aggregate together in clumps encapsulated by a quantum solvation shell due to the totally frictionless nature of the superfluid medium the entire object then proceeds to act very much like a nanoscopic ball bearing allowing effectively complete rotational freedom of the solvated chemical species a quantum solvation shell consists of a region of nonsuperfluid helium4 atoms that surround the molecules and exhibit adiabatic following around the centre of gravity of the solute as such the kinetics of an effectively gaseous molecule can be studied without the need to use an actual gas which can be impractical or impossible it is necessary to make a small alteration to the rotational constant of the chemical species being examined in order to compensate for the higher mass entailed by the quantum solvation

treatment and in particular water softening nanofilters soften water by retaining scaleforming divalent ions eg ca2 mg2nanofiltration has been extended into other industries such as milk and juice production as well as pharmaceuticals fine chemicals and flavour and fragrance industries one of the main advantages of nanofiltration as a method of softening water is that during the process of retaining calcium and magnesium ions while passing smaller hydrated monovalent ions filtration is performed without adding extra sodium ions as used in ion exchangers many separation processes do not operate at room temperature eg distillation which greatly increases the cost of the process when continuous heating or cooling is applied performing gentle molecular separation is linked with nanofiltration that is often not included with other forms of separation processes centrifugation these are two of the main benefits that are associated with nanofiltration nanofiltration has a very favorable benefit of being able to process large volumes and continuously produce streams of products still nanofiltration is the least used method of membrane filtration in industry as the membrane

to fall out of favor this cultural change likely had to do with the rise of the scientific method and the emphasis on a plain style of speaking and writing even todays formal oratory is much less ornate than in the classical era ancient china had a delayed start to implementing rhetoric persuasion because there were no rhetoricians training students it was understood that chinese rhetoric was part of chinese philosophy which schools taught focusing on two concepts wen ” rhetoric and “ zhi ” thoughtful content ancient chinese rhetoric shows strong connections with modern public speaking as chinese rhetoric placed a high value on ethicsancient chinese rhetoric had three objectives i using language to reflect peoples feelings ii using language to be more pointed effective and impactful and iii using rhetoric as an aesthetic tool chinese rhetoric traditionally focused more on the written than the spoken word but both share similar characteristics of constructiona unique and key difference between chinese and western rhetoric is the audience targeted for persuasion in chinese rhetoric state rulers were the audience whereas western rhetoric targets the public another difference between chinese and western rhetoric practices is how a speaker establishes credibility or ethos in chinese rhetoric the speaker does not focus on individual credibility like western rhetoric instead the speaker focuses on collectivism by sharing personal experiences and establishing a connection between the speakers concern and the audiences interestchinese rhetoric analyses public speakers on three standards i tracing which is how well the speaker is doing compared to traditional speaking practices ii examination or how the speaker considers the audiences daily lives and iii practice which is how relevant the topic or argument is to the state society and people aristotle and one of his most famous writings rhetoric written in 350 bce have been used as a foundation for learning how to master the art of public speaking in his works rhetoric is the act of publicly persuading an audience rhetoric is similar to dialect he defines both as being acts of persuasion however dialect is the act of persuading someone in private whereas rhetoric is about persuading people in a public setting aristotle defines someone who practices rhetoric or a rhetorician as an individual who can comprehend persuasion and how it is appliedaristotle divides rhetoric into three elements i the speaker ii the topic or point of the speech and iii the audience aristotle also classifies

that classical rhetoric and rapoports pavlovian strategy and freudian strategy all share the common goal of controlling or persuading someone else but the rogerian strategy has different assumptions about humanity and a different goal in young becker and pikes view the goal of rogerian rhetoric is to remove the obstacles — especially the sense of threat — to cooperative communication mutual understanding and mutual intellectual growth they considered this goal to be a new alternative to classical rhetoric they also said that classical rhetoric is used both in dyadic situations — when two parties are trying to understand and change each other — and in triadic situations — when one party is responding to an opponent but is trying to influence a third party such as an arbitrator or jury

article argued that the three principles of rogerian strategy that they borrowed from rapoport could be found in various parts of aristotles writings and so were already in the classical tradition she pointed to book i of aristotles rhetoric where he said that one must be able to understand and argue both sides of an issue and to his discussions of friendship and of the enthymeme in book ii and to similar passages in his topics she also saw some similarity to platos phaedrus other scholars have also found resonances between rogerian and platonic rhetorics of dialogueenglish professor paul g

it is often observed that otype stars are preferentially located in the center of a young cluster after relaxation the speed of some low mass members can be greater than the escape velocity of the cluster which results in these members being lost to the cluster this process is called evaporation a similar phenomenon explains the loss of lighter gases from a planet such as hydrogen and helium from the earth — after equipartition some molecules of sufficiently light gases at the top of the atmosphere will exceed the escape velocity of the planet and be lost through evaporation most open clusters eventually dissipate as indicated by the fact that most existing open clusters are quite young globular clusters being more tightly bound appear to be more durable the relaxation time of the milky way galaxy is approximately 10 trillion years on the order of thousand times the age of the galaxy itself thus any observed mass segregation in our galaxy must be almost entirely primordial

called superionic ice or ice xviii is a phase of water that exists at extremely high temperatures and pressures in superionic water water molecules break apart and the oxygen ions crystallize into an evenly spaced lattice while the hydrogen ions float around freely within the oxygen lattice the freely mobile hydrogen ions make superionic water almost as conductive as typical metals making it a superionic conductor it is one of the 19 known crystalline phases of ice superionic water is distinct from ionic water which is a hypothetical liquid state characterized by a disordered soup of hydrogen and oxygen ions while theorized for decades it was not until the 1990s that the first experimental evidence emerged for superionic water initial evidence came from optical measurements of laserheated water in a diamond anvil cell and from optical measurements of water shocked by extremely powerful lasers the first definitive evidence for the crystal structure of the oxygen lattice in superionic water came from xray measurements on lasershocked water which were reported in 2019if it were present on the surface of the earth superionic ice would rapidly decompress in may 2019 scientists at the lawrence livermore national laboratory llnl were able to synthesize superionic ice confirming it to be almost four times as dense as normal ice and black in colorsuperionic water is theorized to be present in the mantles of giant planets such as uranus and neptune as of 2013 it is theorized that superionic ice can possess two crystalline structures at pressures in excess of 50 gpa 7300000 psi it is predicted that superionic ice would take on a bodycentered cubic structure however at pressures in excess of 100 gpa 15000000 psi and temperatures above 3140 degrees fahrenheit it is predicted that the structure would shift to a more stable facecentered cubic lattice the ice appears black in color demontis et al made the first prediction for superionic water using classical molecular dynamics simulations in 1988 in 1999 cavazzoni et al predicted that such a state would exist for ammonia and water in conditions such as those existing on uranus and neptune in 2005 laurence fried led a team at lawrence livermore national laboratory to recreate the formative conditions of superionic water using a technique involving smashing water molecules between diamonds and super heating it with lasers they observed frequency shifts which indicated that a phase transition had taken place the team also created computer models which indicated that they had indeed created

collaboration of scientists the aim was to study the processes of galaxy formation and evolution in the universe with a comprehensive physical model early results were described in a number of publications following widespread press coverage the project publicly released all data produced by the simulations in april 2015 key developers of the illustris simulation have been volker springel maxplanckinstitut fur astrophysik and mark vogelsberger massachusetts institute of technology the illustris simulation framework and galaxy formation model has been used for a wide range of spinoff projects starting with auriga and illustristng both 2017 followed by thesan 2021 millenniumtng 2022 and tngcluster to be published in 2023 the original illustris project was carried out by mark vogelsberger and collaborators as the first largescale galaxy formation application of volker springels novel arepo codethe illustris project included largescale cosmological simulations of the evolution of the universe spanning initial conditions of the big bang to the present day 138 billion years later modeling based on the most precise data and calculations currently available are compared to actual findings of the observable universe in order to better understand the nature of the universe including galaxy formation dark matter and dark energythe simulation included many physical processes which are thought to be critical for galaxy formation these include the formation of stars and the subsequent feedback due to supernova explosions as well as the formation of supermassive black holes their consumption of nearby gas and their multiple modes of energetic feedbackimages videos and other data visualizations for public distribution are available at official media page the main illustris simulation was run on the curie supercomputer at cea france and the supermuc supercomputer at the leibniz computing centre germany a total of 19 million cpu hours was required using 8192 cpu cores the peak memory usage was approximately 25 tb of ram a total of 136 snapshots were saved over the course of the simulation totaling over 230 tb cumulative data volumea code called arepo was used to run the illustris simulations it was written by volker springel the same author as the gadget code the name is derived from the sator square this code solves the coupled equations of gravity and hydrodynamics using a discretization of space based on a moving voronoi tessellation it is optimized for running on large distributed memory supercomputers using an mpi

burrowing animals and anthills it is a term used in archaeology and anthropology to describe similar implements which usually consists of little more than a sturdy stick which has been shaped or sharpened and sometimes hardened by being placed temporarily in a firefashioned with handles for pulling or pushing it forms a prehistoric plough and is also described as a type of hoe digging sticks more than 170000 years old made of boxwood by neanderthals have been found in italy in mexico and the mesoamerican region the digging stick was the most important agricultural tool throughout the regionthe coa stick normally flares out into a triangle at the end and is used for cultivating maize it is still used for agriculture in some indigenous communities with some newer 20thcentury versions having the addition of a little metal tipother digging sticks according to native americans of the columbia plateau have been used since time immemorial to gather edible roots like balsamroot bitterroot camas and varieties of biscuitroot typical digging sticks were and are still about 2 to 3 feet in length usually slightly arched with the bottom tip shaved off at an angle a 5 to 8 inch crosspiece made of antler bone or wood was fitted perpendicularly over the top of the stick allowing the use of two hands to drive the tool into the ground since contact with the europeans in the 19th century native americans have also adapted the use of a metal in making digging sticks australia digging sticks are used by many of the aboriginal peoples of australia for digging up roots and tubers

than the present proponents of the linear view unlike confucianism and to a certain extent taoism that both search for an ideal past the judeochristianislamic tradition believes in the fulfillment of history which was translated into the idea of progress in the modern age therefore chinese proponents of modernization have looked to western models according to thompson the late qing dynasty reformer kang youwei believed he had found a model for reform and modernisation in the ancient chinese classicsphilosopher karl popper said that progress was not fully adequate as a scientific

homo sapiens among the earliest of their species in eurasia skhul cave is on the slopes of mount carmel qafzeh cave is a rockshelter near nazareth in lower galilee the remains found at es skhul together with those found at the nahal mearot nature reserve and mugharet elzuttiyeh were classified in 1939 by arthur keith and theodore d mccown as palaeoanthropus palestinensis a descendant of homo heidelbergensis the remains exhibit a mix of traits found in archaic and anatomically modern humans they have been tentatively dated at about 80000 – 120000 years old using electron paramagnetic resonance and thermoluminescence dating techniques the brain case is similar to modern humans but they possess brow ridges and a projecting facial profile like neanderthals they were initially regarded as transitional from neanderthals to anatomically modern humans or as hybrids between neanderthals and modern humans neanderthal remains have been found nearby at kebara cave that date to 61000 – 48000 years ago but it has been hypothesised that the skhulqafzeh hominids had died out by 80000 years ago because of drying and cooling conditions favouring a return of a neanderthal population suggesting that the two types of hominids never made contact in the region a more recent hypothesis is that skhulqafzeh hominids represent the first exodus of modern humans from africa around 125000 years ago probably via the sinai peninsula and that the robust features exhibited by the skhulqafzeh hominids represent archaic sapiens features rather than neanderthal features the discovery of modern human made tools from about 125000 years ago at jebel faya united arab emirates in the arabian peninsula may be from an even earlier exit of modern humans from africa in january 2018 it was announced that modern human finds at the mount carmel cave of misliya discovered in 2002 had been dated to around 185000 years ago giving an even earlier date for an outofafrica
