The bi-conductive surfaces have a periodic arrangement of low-conductivity material embedded within a high-conductivity substrate. The thermal conductivity of the epoxy (<1 W/mK) is several orders of magnitude less than that of copper (~400 W/mK). When submerged in a fluid and heated from the underside, this creates an in-plane variation in surface temperature. Due to the extreme conductivity difference, there is negligible heat conducted through the epoxy divisions during nucleate boiling (see thermal circuit analysis in the Supplementary Material). As such, the wall superheat temperature above the epoxy divisions will be notably reduced as compared to that experienced over the copper sections. At low average wall superheats, prior to bubble nucleation, these in-plane temperature variations will drive natural convection flows aligned with the epoxy divisions similar to Rayleigh-Bérnard convection rolls. It has been shown that this sort of flow instability is immediately triggered for any finite superheating with a spatially varying surface temperature27. The resulting flow-field draws cooler liquid down toward the surface from above the epoxy divisions, while warmer fluid rises from above the hot copper. At these early stages the counter-rotating flows will produce a stagnation point in the center of the copper, resulting in a local minimum in convective heat transfer coefficient and therefore a local maximum in surface temperature28. As the wall superheat is increased this local maximum temperature promotes bubble nucleation along the center of the copper regions. This results in the formation of an ordered flow-field, as shown schematically in Fig. 1e, which persists at increasing thermal loadings. The in-plane variations in wall superheat take a periodic form with a wavelength equal to the pitch between epoxy divisions, P. This superheat wavelength dictates the nature and location of the ordered pathways of escaping vapor and replenishing liquid returning to the surface during nucleate boiling. Figure 1f shows an image of the onset of nucleate boiling, where the first few nucleation sites are activated on a bi-conductive surface (N = 4 cm−1) at a wall superheat of ~5 K. As can be seen, the vapor bubbles preferentially nucleate near the center of the copper due to the local maximum in surface temperature. This is consistently seen for all of the surfaces tested, and demonstrates that the wettability of the epoxy is not promoting nucleation due to a lower surface energy (see supplemental movies). Additionally, Fig. 1g shows how the superheat wavelength, P, imparts a level of control over the bubble diameter during lateral coalescence. By ordering nucleation sites and liquid return pathways, the size of bubbles undergoing lateral coalescence across an epoxy division is tuned to nominally coincide with the superheat wavelength, P.

“I feel better now that I’m not afraid to speak to them,” Lee said. “Before I was really scared. After talking with him (Reyes), I really like him. I like this place. It’s really coming along.”

The photograph is often described in art history as if it was a window, but what happens when we step through the window of the picture plane, and into the image itself? Because such images have no natural scale, we might find ourselves suddenly bigger, or smaller, than we expect. For people entering Svizzera 240, this whimsical problem was made concrete. The interior of the pavilion was remapped as a series of rooms whose scale distorted to fill the available space, even as all the fittings, from door handles to wood grain, remained meticulously Swiss standard issue. Visitors would move, increasingly dismayed, from one room to another, feeling themselves smaller, and then larger. With another person in the room—are they standing as far away as we think they are, or are they taller or shorter than we thought? Much like a hike on a glacier in which an inexperienced walker, without the benefit of familiar forms, slowly loses their bearings and is unable to tell if a ridge is an hour away or a day’s march, visitors pleasurably lose their bearings in a space where the objects are familiar, but scale is no longer trustworthy. Architectural historians and critics, walking through the rooms in Svizzera 240, would try to orient themselves via history. Some spoke of mannerism, others of Borromini. The playfulness of the installation, and the pleasure it brought, was also a rejection of functionalism in favor of a baroque, self-reflexive exploration of possibilities, of the rules of a game pushed to its limits. To go, within a few sentences, from minimalism to mannerism (let alone to the Baroque) requires some critical agility. Mannerism and minimalism would seem, on the face of it, to contradict each other. But there is an inner affinity: both mannerism and minimalism explore not just content, but the coordinates of experience. They don’t just make things bigger or smaller, they stretch and compress time and space, wringing meaning out of the grid like some deviant topologist. What the exhibition recalled—for it is a canonical lesson, but one worth retelling—was how the seeming minimalism of the rooms, their sameness, could sensitize the viewer to subtle shifts and could produce on an experiential level a kind of maximalism.

Real-time traffic information helps you to avoid congestion, and plan alternative routes. But if you are delayed, the ‘Share ETA Mode’ can send your location and estimated time of arrival to chosen contacts via email or text message1. If your journey time slips, the system can automatically send further updates.

The differences are mostly in features and price. A 40″ TV is under $200 at Walmart right now. Monitors anywhere near that large tend to be 4k or curved and so command a premium, most are at least $400, closer to $600 or more. A television has a tuner and a user interface that may be useless without a remote control, a monitor has a resolution appropriate for it’s size at a viewing distance of an arm’s length, no tuner, and a UI that is set with buttons on the device and then forgotten forever. A television tends to have some analog input options for composite and split video signals along with HDMI, while a monitor will tend to have an RGB input (VGA) if any analog, as well as some displayport or DVI ports in addition to HDMI if present.

“It’s been kind of a community project also with a lot of help from friends and neighbors and stuff like that,” Darwin said. “They supported Leighton all the way through high school, and they’re still supporting him now.”

WASHINGTON — Members of a special joint committee tasked with recommending ways to overhaul spending practices say Congress’ current budgeting system is broken, but they aren’t ready to recommend any steps to improve matters.

Caseology is a relatively well-established case brand, but their products have mostly been overshadowed on retailers like Amazon by more popular offerings from other manufacturers like Spigen. But if you search "Pixel 2 XL case" on Amazon right now, the Vault comes up as the first result with an ‘Amazon’s Choice’ banner next to its photo. After some hands-on time with it, I totally understand why.

The Range Rover Velar debuts the all-new Touch Pro Duo infotainment system, which is the latest infotainment system to be developed by Jaguar Land Rover. Touch Pro Duo features two high-definition 10-inch touchscreens that form the centerpiece of the beautifully minimalist cabin, and blends a futuristic, elegant feel with an intuitive, engaging interface and exceptional functionality1.

The shell mold consists of a highly polished metal mold of the helmet that is surrounded by several moving parts that have the same shape.

One afternoon in the studio, Ive sketched the Apple Watch as seen from the side, with the crown asymmetrical on two axes: nearer the top of the watch than the bottom, and nearer the face than the back. (There is also a more flush secondary button.) As an afterthought, he quickly drew the front of an iPod: a rectangle within a rectangle, and a circle within a circle. He pointed at the watch drawing. “It’s not for us to say if things are iconic,” he said, and then described it as a “very, very iconic view.” Ive explained that, had he centered the Digital Crown, the watch would be a quite different product. “It’s just literal. And you could say, ‘Why is that an issue?’ Well, if it’s literally referencing what’s happened in the past, the information about what it does is then wrong.” The crown rotates, which is reassuring, but it doesn’t wind the watch or adjust hands. The goal, Ive said, was to create “the strangely familiar.”
