Question: What type of group does SWMRS and We the Kings have in common?
Context: A class rating is an allowance to fly a certain group of aircraft that require training common to all aircraft within the group.  A type rating is specified if a particular aircraft requires additional specialized training beyond the scope of initial license and aircraft class training.  What aircraft require a type rating is decided by the local aviation authority.  Almost all single engine piston (SEP) or multi engine piston (MEP) single pilot aircraft can be flown without a "type rating", but are covered by a "class rating" instead.  An exception to this under European Aviation Safety Agency (EASA) regulations is the piston version of the Piper Malibu. Multi-male groups, also known as multi-male/multi-female, are a type of social organization where the group contains more than one adult male, more than one adult female, and offspring.  Within Order Primates, it is the most common social group type, with group sizes ranging from 10 to 100 individuals.  Large groups of primates are called "troops."  Examples of species that can be categorized under this type of social organization include many diurnal lemurs, langurs, and most members of the family Cebidae. SWMRS (formerly Emily's Army) is an American punk rock band formed in Oakland, California in 2004 by Cole Becker and Joey Armstrong, with Cole's brother Max joining only a few weeks afterwards.  They drew on a mix of influences ranging from the Beach Boys to the Ramones to create their own brand of rock.  The band added Travis Neumann in 2009, who later left in 2014 due to creative differences.  The band released a demo and a string of EPs from 2008 to 2010.  The band released their first album, "Don't Be a Dick", on June 14, 2011.  The band's second album, "Lost at Seventeen", was released on June 11, 2013.  They added Sebastian Mueller as the bassist 2014.  The band's third studio album, and their first under the name SWMRS after dropping their former name, "Drive North", was released February 12, 2016, via Uncool Records. " Drive North" was later re-released and remastered after the band was signed to record label Fueled By Ramen on October 13, 2016. Metal-catalyzed C–H borylation reactions are transition metal catalyzed organic reactions that produce an organoboron compound through functionalization of aliphatic and aromatic C–H bonds and are therefore useful reactions for carbon–hydrogen bond activation.  Metal-catalyzed C–H borylation reactions utilize transition metals to directly convert a C–H bond into a C–B bond.  This route can be advantageous compared to traditional borylation reactions by making use of cheap and abundant hydrocarbon starting material, limiting prefunctionalized organic compounds, reducing toxic byproducts, and streamlining the synthesis of biologically important molecules.  Boronic acids, and boronic esters are common boryl groups incorporated into organic molecules through borylation reactions.  Boronic acids are trivalent boron-containing organic compounds that possess one alkyl substituent and two hydroxyl groups.  Similarly, boronic esters possess one alkyl substituent and two ester groups.  Boronic acids and esters are classified depending on the type of carbon group (R) directly bonded to boron, for example alkyl-, alkenyl-, alkynyl-, and aryl-boronic esters.  The most common type of starting materials that incorporate boronic esters into organic compounds for transition metal catalyzed borylation reactions have the general formula (RO)B-B(OR).  For example, Bis(pinacolato)diboron (BPin), and bis(catecholato)diborane (BCat) are common boron sources of this general formula. In common law, a petit jury (or trial jury, sometimes petty jury) hears the evidence in a trial as presented by both the plaintiff (petitioner) and the defendant (respondent).  After hearing the evidence and often jury instructions from the judge, the group retires for deliberation, to consider a verdict.  The majority required for a verdict varies.  In some cases it must be unanimous, while in other jurisdictions it may be a majority or supermajority.  A jury that is unable to come to a verdict is referred to as a hung jury.  The size of the jury varies; in criminal cases involving serious felonies there are usually 12 jurors, although Scotland uses 15.  A number of countries that are not in the English common law tradition have quasi-juries on which lay judges or jurors and professional judges deliberate together regarding criminal cases.  However, the common law trial jury is the most common type of jury system. Horntail or wood wasp is the common name for any of the 150 non-social species of the family Siricidae, of the order Hymenoptera, a type of xylophagous sawfly.  This family was formerly believed to be the sole living representative of the superfamily Siricoidea, a group well represented in Paleogene and Mesozoic times, but the family Anaxyelidae has been linked to this group.  There are ten living genera placed in the family, and an additional three genera described from fossils.  The last tergite of the abdomen has a strong, projecting spike, thus giving the group its common name (the ovipositor is typically longer and also projects posteriorly, but it is not the source of the name).  A typical adult horntail is brown, blue, or black with yellow parts, and may often reach up to 4 cm long.  The pigeon horntail ("Tremex columba") can grow up to 5 cm long (not counting the ovipositor), among the longest of all Hymenoptera. Bird's eye maple, or bird's eye extinction, is a specific type of extinction exhibited by minerals of the mica group under cross polarized light of the petrographic microscope.  It gives the mineral a pebbly appearance as it passes into extinction.  This is caused when the grinding tools used to create petrographic thin sections of precise thickness alter the alignment of the previously perfect basal cleavage planes which split micas up into its characteristic thin sheets.  The resulting, slightly roughened surface alters the extinction angle of various parts of the crystal lattice, leading to this type of extinction.  Since it is not a natural feature of the mineral, bird's eye maple is not observed in all mica crystals, nor from all angles, but it is quite common, and is used as a diagnostic feature for micas. We the Kings is an American rock band from Bradenton, Florida.  The band's self-titled full-length debut album, released in 2007, included the platinum single "Check Yes Juliet", and went on to sell over 250,000 copies in the US.  The group's second album "Smile Kid" (2009) included Top 40 singles "Heaven Can Wait" and "We'll Be a Dream" (featuring Demi Lovato), as well as the single "She Takes Me High". Coronary artery disease (CAD), also known as ischemic heart disease (IHD), is a group of diseases that includes: stable angina, unstable angina, myocardial infarction, and sudden cardiac death.  It is within the group of cardiovascular diseases of which it is the most common type.  A common symptom is chest pain or discomfort which may travel into the shoulder, arm, back, neck, or jaw.  Occasionally it may feel like heartburn.  Usually symptoms occur with exercise or emotional stress, last less than a few minutes, and get better with rest.  Shortness of breath may also occur and sometimes no symptoms are present.  The first sign is occasionally a heart attack.  Other complications include heart failure or an irregular heartbeat. A thiosulfoxide is a chemical compound containing a sulfur to sulfur double bond of the type RR'S=S with R and R' both alkyl or aryl residues.  The thiosulfoxide has a molecular shape known as trigonal pyramidal.  Its coordination is also trigonal pyramidal.  The point group of the thiosulfoxide is C.  A 1982 review concluded that there was as yet no definitive evidence for the existence of stable thiosulfoxides which can be attributed to the double bond rule which states that elements of period 3 and beyond do not form multiple bonds.  The related sulfoxides of the type RR'S=O are very common.  Many compounds containing a sulfur-sulfur double bond have been reported in the past although only a few verified classes of actually stable compounds exist, closely related to thiosulfoxides.
