Fire crews have been battling the blaze since lunchtime.The fire is about 90 percent contained and only burned about 2 acres, but that’s because of the fire crews working fast over a three hour period. Flames could have easily spread to Miramar National Cemetery.Officials stated the fire is under control, but expect to be there until it is fully contained.No structures, including the cemetery, and no injuries have been reported at this time.

Behind Brockhamptons Texas Triumph At Austin City Limits Festival


first_img Facebook Email Go inside the boy band’s prolific—and tumultuous—path to its big-time Texas homecomingRiley Van StewardGRAMMYs Oct 6, 2018 – 9:55 am Beneath the sweltering heat of the Texas sun, Zilker Park bristles with the tents, stages and sounds of the Austin City Limits Festival (ACL.) Every wristband and sign is a bright collage of colors and bold fonts, and every act comes onstage to the screams of fans so enamored by the music and culture of this festival that they are willing to brave the Texas sun. For fans and artists alike, ACL perfectly captures the feeling of Austin.No act better encapsulates this mix of emotions, feelings and spirit than Brockhampton. The Internet generation’s most prominent boy band has recently been rocked by controversy, album delays, album cancellations, and label signings, but they have come to the heart of the lone-star state triumphant on the heels of their No. 1 album, Iridescence.Nine months ago, they were a different band. They were focusing more on rap lead by the cover boy of all three of the Saturation trilogy, Ameer Vann. Their sound was not mainstream by any stretch of the imagination, yet its roots were clearly in the emerging anti-pop rap of Tyler, the Creator and Odd Future. On Iridescence, Brockhampton has escaped all comparison to their predecessors. The sound is experimentally shifting from rap to electronic psychedelia, tapping into the same teen-angst that built such a loyal fan base.Few other artists could claim a following so loyal—and at times impatient—as to complain about a nine-month wait between albums. The crowd made their thoughts clear: it was worth the wait. Twitter Behind Brockhampton’s Texas Triumph At Austin City Limits Festival News https://twitter.com/brckhmptn/status/1042989775983063041 Brockhampton’s Texas-Sized Triumph At ACL behind-brockhamptons-texas-triumph-austin-city-limits-festival Still prolific by most artists’ standards, the gap grew to nine months as Brockhampton met challenges and controversy. Their frontman and cover boy, Ameer Vann, often touted as the most talented rapper of the group by leader Kevin Abstract, faced a wave of allegations beginning on Twitter of physical and emotional abuse. The band was quick to respond, kicking Vann out and disavowing his actions. Vann had been an integral piece of the boy band’s image. They often stated that the quality of their music came from the quality of their friendship. So, fans were wary of the impact this would have on the mental-health and stability of the group. In many minds, this tour was Brockhampton’s response.Taking the stage in all black, Dom Mclennon lead the group out to “New Orleans.” A technical difficulty stopped his mic from working for the beginning of the song, but didn’t stop McLennon, who continued as if nothing happened. The show had begun, and Abstract proclaimed that Brockhampton is “The greatest boy band on earth” to the screams of the crowd.When Kevin asked his fans to put their arms up “Like you’re on a rollercoaster,” the simile was followed by thermal point-of-view images from a rollercoaster displayed on stage. The level of intricacy and detail on the screen behind the band was almost as exciting as the artists’ wild dances across the stage. On screen were shadow-puppets, close-ups, and cartoonish font spelling “peanut butter.” Visuals switched between highly saturated thermal imaging and black-and-white to fit the mood of the music. Often members of the band would kneel while they were not performing. And, then suddenly the group would erupt in monsterish, bold dance moves feeding off the energy of the crowd and each other.Some of the slickest twists were their performance of older songs. Instead of repeating the recorded renditions in a way that may clash with the new style of Iridescence, Brockhampton updated their classics to fit the tone of this new album and era. The greatest example was McLennon’s verse on “Bleach.” His call for moral action in an immobile society previously performed as pseudo-spoken word poetry turned to a soulful ballad.“Boogie” was the finale of this lively ordeal. The light swoon of a violin introduced what is easily the group’s most rambunctious, least-classically inspired single, and still the violin somehow fit into the larger narrative the group weaved on stage. They may be wild, they may be crazy as the Lone Star State itself, they may even be eclectic but their music speaks volumes beautifully and directly to the internet generation.Hozier Opens Up About “Nina Cried Power,” Reveals What’s On His PlaylistRead morelast_img read more

Oooh, ahhh, indeed. At $250, the compact Rylo dual-lens camera is selling for its lowest price yet. And for an extra $50, you can get the bundle that includes the waterproof housing.This deal runs through Sept. 3; it usually costs $500. LG G8 ThinQ Angela Lang/CNET LG’s 2019 flagship, the G8 ThinQ, is almost ready for your pocket. It launched at MWC this year, but now we know that you’ll be able to preorder it in the US starting March 29. The company’s offering a limited-time promotion for $150 off the retail price of $820 (for qualified buyers), and it will start dropping into hands on April 11.Initial sales will be through LG’s usual suspects: AT&T, Best Buy, B&H, Sprint, T-Mobile, US Cellular, Verizon, and Xfinity Mobile.   The G8’s headline feature is its vein-reading hand-sign-in security with a limited set of touchless gesture controls using the front-facing camera. While we weren’t impressed by the execution of these features — they felt distinctly first-gen — and it had to compete with more buzzworthy foldable phones like the Samsung’s Galaxy Fold announced at the same time, we did see promise in the technology. I thought this might be a mistake, but, no, the weirdly named HP Laptop 15t Value is indeed quite the value at this price. Specs include an Intel Core i7 processor, 12GB of RAM, a 256GB solid-state drive and a 15.6-inch display. However, I strongly recommend paying an extra $50 to upgrade that display to FHD (1,920×1,080), because you’re not likely to be happy with the native 1,366×768 resolution.

Wait — no, I’m not. As much as I respect the original intent of the holiday (which became official back in 1894), to most of us, it’s just a bonus day off — one that’s blissfully tacked onto a weekend. So, yeah, stores; go ahead, run your sales. I’m listening. Perhaps unsurprisingly, Labor Day doesn’t bring out bargains to compete with the likes of Black Friday (which will be here before you know it), but there are definitely some sales worth your time.For example:We’ve rounded up the best Labor Day mattress deals.We’ve also gathered the best Labor Day laptop deals at Best Buy.The 2019 Vizio P Series Quantum is back under $999.Be sure to check out Amazon’s roughly three dozen Labor Day deals on TVs and audio.

Midge swarms show mechanical properties behave as a viscoelastic material


first_imgMean swarm response to an oscillating swarm marker. (A) Trajectories (>40 s long) of individual midges (each color corresponding to a different midge) are individually convoluted but remain localized over the ground-based swarm marker (black square). (B) Sketch of our experimental setup. Swarms form inside a plexiglass cube measuring 122 cm on a side and are imaged using three cameras mounted outside the enclosure. The swarm marker (in dark gray) is mounted on a linear stage (in red) that can be oscillated over a range of controlled frequencies and amplitudes along the direction indicated by the white arrows, which we label as the x direction. z increases vertically from the swarm marker (antiparallel to gravity), with the marker itself at z = 0. Midge development tanks (light blue) and four infrared light-emitting diode arrays (yellow; additional arrays on top of the enclosure are not shown) are also shown. (C) Phase-averaged position of the center of the swarm marker XM and the center of mass of the swarm XS. The swarm center of mass tracks the sinusoidal motion of the marker, although with a reduced amplitude and a phase lag. (D) The amplitude of the swarm center-of-mass motion AS as a function of the amplitude of the marker motion AM for two different oscillation frequencies, showing a linear relationship between the two. The shaded area shows the SEM. Microrobots that can form into multiple types of swarming shapes A team of researchers from Stanford University and Rothamsted Research, has found that midge swarms have some types of mechanical properties and also respond to a stimulus at times as a viscoelastic. In their paper published in the journal Science Advances, the group describes their study of swarm behavior in a species of midges and what they found.

Midges are an unofficial classification of two-winged fly. There are many species, most of which are associated with swarms that live near water or marshy areas. In this new effort, the researchers wanted to learn more about the physical properties of swarming behavior from the perspective of an entire swarm, rather than the individuals in it. To that end, they obtained a mass of male Chironomus riparius, which are known to swarm over a given object such as a tree stump as part of their mating ritual—the swarm allows the females to find them from a distance. In their lab, the researchers placed a square of black felt on the bottom of a tank for the midges to use as their orienting object. When the piece of felt was moved, the swarm responded to it. To test swarm responses to it, the felt square was attached to a small oscillating device.The researchers report that they focused specifically on how the swarm responded as an entire unit to the moving object below them. They report that it behaved in a layered manner, with those closest to the moving object responding faster than those in more distant layers. The researchers suggest this was likely due to propagation delays in messaging between individuals. They also observed mechanical properties—and sometimes the swarm behaved elastically, while at other times it behaved more like a viscous liquid—which, in physics terms, meant it was behaving like a viscoelastic material. They also found that sometimes, the viscosity properties were overcome by the elastic properties, which led to an observed dampening effect of the swarm’s overall movement. The researchers suggest this made the swarm more stable, making it easier for the females to find it. They also suggest their findings might have some relevance to swarming robotics efforts.last_img read more
