Comparison - sCMOS vs. CCD technology; lower figure compares a scientific grade CCD (left) and a pco.edge camera with sCMOS sensor (on the right) under similar weak illumination conditions. This demonstrates the superiority of sCMOS over CCD with regards to read out noise and dynamic, without smear (the vertical lines in the CCD image).

A standing wheelchair is an automated device that assists its user in moving from a seated, to standing position and oftentimes back to flat if the chair has the capabilities of doing so. Standing wheelchairs are common among individuals with: muscular dystrophy, multiple sclerosis, and other ailments that compromise mobility functions.

A drawing of the Royal Opera House, Covent Garden, where Michael Arne primarily worked from 1777 until his death. This drawing was made shortly before the theatre burned down in 1808. Many of Arne's compositions dating from his time there, along with a large amount composed by his father, were destroyed in this fire and are now lost.[3]

Number of captured N. pompilius at various depths around the Osprey Reef Seamount, Coral Sea. The data was collated from 271 trapping events spread across all months of the year. Nautiluses were most common at 300–350 m (1,000–1,100 ft). No specimens were recovered from a depth of less than 150 m (500 ft) during 18 trapping efforts.[15]
Original caption: "The influence of depth on capture rates was analyzed for 271 trapping events spread throughout all months of the year. The most effective capture depths were around 300 to 350 m, while no captures were recorded from 18 trapping efforts at depths <150 m. Error bars (±1 standard error of the mean) are shown."

Deutsch: Foto einer Aufnahme des Kircheninneren aus der Zeit vor Einführung der Elektrizität in Bonndorf. Das genauer Datum der Aufnahme ist nicht eindeutig, müsste aber um 1900 sein. Folgende Anhaltspunkte mögen dafür angebracht sein: Ab 1905 gab es in Bonndorf, durch das Städtische Elektrizitätswerk (Gleich-) Strom in Bonndorf. Die Kirche wurde nach 1905 mittels eines Kronleuchters, welcher in der Mitte des Hauptschiffes hing, beleuchtet. Die Kanzel ist die, welche 1850 beim Bau der Kirche eingebaut wurde. Diese wurde später durch eine größere mit vier Holzreliefs (Kirchenlehrer) ersetzt. Die Kreuzwegstationen müssen ebenfalls die von 1850 sein, denn heute sind andere Kreuzwegstationen vorhanden, die auf Simmler zurückgehen sollen. Die Wandflächen bei den Kreuzwegstationen sind heute nicht mehr mit Ornamentmalereien versehen. Die in der Mitte stehende Weihnachtskrippe geht auf Simmler zurück und steht heute in der Hauskapelle des Alten- und Pflegeheims St. Laurentius, der früheren "Spitalkapelle".
Orașul ideal este o pictură realizată de Fra Carnevale, cândva între 1480 și 1484. Pictura, aflată actualmente la Walters Art Museum din Baltimore, statul Maryland, exemplifică foarte bine ideile de planificare urbană ideală ale Renașterii, folosind elemente evidente de arhitectură romană și greacă axate pe o planificare de tip central.
English: This extraordinary panel exemplifies Renaissance ideals of urban planning, respect for Greco-Roman antiquity, and the mastery of central perspective. The imaginary city square features a Roman arch typically erected as a commemoration of military victory at its center. As a whole, the painting offers a model of the architecture and sculpture that would ideally be commissioned by a virtuous ruler who cares for the welfare of the citizenry. The amphitheater is modeled on the Colosseum in Rome. The octagonal structure to the right, covered with colored stone, suggests the medieval Baptistery in Florence, which in the 15th century was thought to be a reused Roman temple. Together they reflect the importance of security, religion, and recreation in a well-regulated city and the value of Roman ideals in urban design. The private residences at either side are also dignified with classical architectural elements. Classicizing elements also appear in the foreground. Statues, set on columns in the Roman style, represent virtues of a good ruler, including Justice with her sword and scales and Liberality (generosity) with a cornucopia. This view and two related paintings (now in Urbino and Berlin) were apparently commissioned for the palace of Duke Federico da Montefeltro of Urbino. Set into the woodwork at shoulder height or higher, "The Ideal City" would have seemed like a window onto another, better world. The illusion of a space that extends out from our own is achieved using a mathematical perspective system developed in Florence. The space is defined in terms of the viewer's own angle of vision: the receding lines establishing spatial relationships converge at a central point in the city gate visible beneath and beyond the Roman arch.
