![]() The exact master equation for the generalized QBM also has potential applications to photonics quantum computing. ![]() We find that the so-called “initial jolt,” which has been thought to be an artificial effect due to the use of the initial decoupled system-environment states, has nothing to do with the initial decoupled state. With the exact master equation for both the initial decoupled and initial correlated states, the issues about the initial jolt are also reexamined. In the Hu-Paz-Zhang master equation, such a renormalized potential is misplaced so that the correct renormalization Hamiltonian has not been found. We find that the renormalized system Hamiltonian after tracing out all the environmental states induced naturally a momentum-dependent potential, which shows the consistency of including the momentum-dependent coupling in the QBM Hamiltonian. A single realization of a one-dimensional Wiener process A single realization of a three-dimensional Wiener process. ![]() It is a white noise with a variance proportional to the temperature. The fluctuation force is similar to that employed in the classical case. The Hu-Paz-Zhang master equation of the conventional QBM model is reproduced as a special case. Brownian Motion and Quantum Mechanics Roumen Tsekov A theoretical parallel between the classical Brownian motion and quantum mechanics is explored. We propose a Langevin equation to describe the quantum Brownian motion of bounded particles based on a distinctive formulation concerning both the fluctuation and dissipation forces. We discuss the physical realizations of the generalized QBM in different physical systems, and derive its exact master equation for both the initial decoupled states and initial correlated states. The generalized QBM can capture more physical applications because the single-particle transition and the two-particle pair production between the system and the environment represent two very different physical processes that usually do not have the same coupling strengths. ![]() The conventional QBM model corresponds to the special case W k = V k. The resulting Hamiltonian in the particle number representation is given by H t o t = ℏ ω S a † a + ∑ k ℏ ω k b k † b k + ∑ k ℏ ( V k a † b k + V k * b k † a ) + ∑ k ℏ ( W k a † b k † + W k * b k a ). This opens a potentially new method of studying the quantum-to-classical transition.In this paper we generalize the quantum Brownian motion (QBM) to include the momentum-dependent system-environment couplings. We do it for realistic, thermal environments and show their noise-robustness. Here we derive an example of objective states of motion in quantum mechanics by showing the formation of dynamical spectrum broadcast structures in the celebrated, realistic model of decoherence -Quantum Brownian Motion. However, two fundamental problems have arisen: a description of objective motion and applicability to other types of environments. It was recently derived in terms of spectrum broadcast structures for small objects embedded in noisy photon-like environments.

The former couple even launched their YouTube channel titled Jules & Stephen Jones and it is rumored that they collaborated for a clothing brand. Then, in 2019, Stephen confirmed from his Facebook that he and Julia have been engaged since March 2019. In fact, the duo also got engaged in December 2017. Julia and Stephen had been as one since March when season 4 ended. She found out that they stopped talking two days before the recording of The Aftermatch. Julia herself claimed that she and Stephen will never be together again in light of the time she spent in Las Vegas. You’re reaching out to the wrong person, he said. ![]() They broke up after McHugh cheated on Rose with a girl named ‘Hannah’ in season 5 of the show Are You The One?.įor what reason would he come to Las Vegas in case he was involved with you? Maybe you should ask her that, Hannah replied before encouraging Julia to talk to her ex in secret. Meanwhile, his girl was dating a person called Stephen McHugh and they even almost got married. Previously, Jake Paul was also linked with stars like Erika Costell and Alissa Violet. In fact, Paul’s dating history is even more complicated than that of his love. Later, Rose posted an overly friendly photo with Mongeau on her Instagram account.Īs of now, it is very clear in 2021 that they are still together and going strong but we don’t know the exact date of when Rose and Paul started dating. The often-seen duo hung out and had fun with Paul’s ex, Mongeau. Julia supported her then-recent boyfriend the entire week before the competition and at events. In 2020, the then-budding couple was seen together in Miami for their boxing match against British YouTuber AnEsonGib on January 30, which her new boyfriend JakePaul dominated in a first-round knockout victory. The pair split in January 2020, and Paul started seeing Rose within a few weeks.Since last year, Julia Rose has been dating her famous boyfriend named Jake Paul. The ceremony was aired both as a $50 pay-per-view event and as part of Mongeau’s MTV reality show, “No Filter: Tana Mongeau.” But the pair reportedly didn’t have a marriage license, so the July 2019 wedding wasn’t legally valid. The former Disney star, who is the brother of fellow social media juggernaut Logan Paul, started dating Rose a month or so after the end of his sham marriage to - you guessed it - social media star Tana Mongeau. ![]() The couple got together after his sham marriage to Tana Mongeau. Paul was spotted having what appeared to be a heart-to-heart talk with buddies at Miami Beach restaurant Papi Steak, according to spies. They added, “He would like to get back together with her and maybe they will, but they both need to slow down their lives.” It’s unclear how Rose would slow her life down, since - if her Instagram is to be believed - she seems to alternate between doing nothing and doing nothing on the beach. They added that the brave little soul has “moved on with other girls” but that “still in his heart she was the one.” Paul is said to be “devastated” over the split. There was much speculation that the pair were kaput last week when Paul tweeted, “Alexa, play ‘I’m Single’ by Jake Paul.” (He released a boldly terrible song of that name in 2019.)īut sources say Paul has been out and about in Miami telling pals that he and Rose are indeed done. More shocking still, it turns out the influencer-turned-boxer may have both thoughts and feelings. ![]() Social-media superstar Jake Paul has split with his Instagram model girlfriend Julia Rose, Page Six has learned. ![]() Plus, there are plenty of area events to keep you entertained if it's too cold to hit the beach.

![]() Easiest Way to Back Up Data from Android SD Card to ComputerĪndroid smartphones and tablets today are the lifeline of many people, which means the data and information contained in the device is very valuable. What if SD Card Data are Lost? How to Back up? Part 1. Back Up Android SD Card to Mac with Android File Transfer Back Up Android SD Card to PC with USB Cable Back Up SD Card on Android with Android Backup Manager Easiest Way to Back Up Data from Android SD Card to Computer So how to back up SD card of Android phone/tablet in fact? There will be simple guides to make it in this post. And keeping a backup of the Android data helps to ensure that there is at least an available copy on your computer, which makes it easy to restore your device with the backup file. ![]() Therefore, the first reason why it's important to ensure that you have backed up your Android regularly is that the device may be stolen or broken. Download the PiShrink script, and make it executable.No one wants to lose important data on the SD card in Android phone or tablet when Android phone is damaged or stolen. If you do not have Linux installed, you can install the latest version of Ubuntu or Linux Mint in a virtual machine, and run this script there. Unfortunately, this tool is only available on Linux. ![]() This also makes copying the image back onto the SD card much faster. To work around this limitation, we will use PiShrink, a script that automatically shrinks a Pi image that will then automatically resize to the max size of the SD card on boot. This is fine if you only have one or two such images, but any more than that (especially if you use an SSD) will cause you to run out of space. ![]() For example, cloning an SD card with a capacity of 32GB will create an image file of 32 GB, even if only 5 GB is actually in use on the card. How to Shrink the Cloned Raspberry Pi Image (Linux-only)Īs mentioned at the starting of the article, these methods create an image file that is equal to the total capacity of the SD card. You can then remove the card from your Mac, and insert it back in the Raspberry Pi. Once the write is complete, you will see a confirmation from dd. Insert the micro SD card that you want to clone in your PC using a USB or built-in card reader. Windows Instructions Backup Raspberry Pi SD Cardġ. There is a method to shrink the image size, but it works only on Linux, and we will be explaining it later in the tutorial. For example, if you have a 16 GB SD card, the resulting image file will also be 16 GB, no matter how much space your installation is actually using. Note: This method will create an image file exactly the size of the SD card’s total capacity. We will explain how to do it on Windows, Linux, and finally macOS. So today, we will learn how to clone or backup the Raspberry Pi micro SD card to an image file, and restore the image after we are done experimenting. In both the above scenarios, it is helpful to have an exact, bit-by-bit identical backup of your working Raspberry Pi installation. Problem is, you only have one micro SD card, and already have a working installation on it that you do not want to lose. Another common scenario is let’s say, you just got to know about a cool new Raspberry Pi-based project or Linux distro, and you are dying to try it out. It was right around when Spears married Alexander, Musial notes, that more and more publications began to slap Spears with the label “white trash”-especially after reports emerged that she’d worn a baseball cap and ripped jeans down the aisle. In doing so, the doc ignores multiple relationships that ignited the public derision toward her in earnest-like her brief dalliance with her back-up dancer, Columbus Short, and her infamously brief marriage to childhood friend Jason Alexander (not of Seinfeld fame) in 2003. It’s difficult to discern why Framing Britney Spears skips straight from Spears’ break-up with Timberlake in 2002 to her engagement to Federline two years later. Kentwood was central to Spears’ public image from her early years her parents, James (AKA “Jamie”) and Lynne Spears, famously scraped by to fund their eldest daughter’s career, even as the former’s contracting business collapsed. Overhead shots of the Kentwood water tower, farmland, and a church steeple play like a screen-saver as the bubbly, heavily accented Felicia Culotta-Spears’ assistant and chaperone for years-explains the town’s “hospitable and humble” nature. To understand how Spears “got here,” her womanhood is just one of several facets of her identity one must unpack.įor instance: How can we talk about the dehumanization of Britney Spears if we never address how her image morphed from that of a darling “small-town girl” from the South, to that of a backwards “white-trash” redneck who deserved no sympathy from the public?Īs with any project concerning Spears, Framing Britney doesn’t waste much time before reminding us all that she hails from the modest town of Kentwood, Louisiana. In reality, misogyny comes in different flavors, depending on other factors including but certainly not limited to a woman’s race, social class, gender expression, and weight. Misogyny certainly poisoned Spears’ relationship with celebrity, but Framing Britney’s examination of the horrible treatment hurled her way feels limited-reliant, above all, on the idea that misogyny is a fixed ideology. Despite the doc’s insistence that “to understand where Britney is now, we should understand how she got here,” the episode itself offers a cherry-picked biography-one that oversimplifies the many societal impulses that converged to dehumanize and torment a young celebrity in distress. But its study of the singer’s life and career in the public eye feels rushed and even superficial at times. More than a decade later, the clip is just one of countless pieces of chilling archival footage included in The New York Times’ explosively popular documentary Framing Britney Spears -which explores the singer’s life and career within the context of the fan-led movement to free her from the conservatorship that has ruled her life for more than a decade.Īvailable on Hulu following its debut on FX, Framing Britney Spears builds on the multiple robustly reported articles the Times has run over the years -each of which have lent gravitas to a fan effort that might otherwise have been written off-and is a handy primer for anyone who’s still not quite sure what cries to #FreeBritney actually mean. Her hair? Ding! Her husband? Ding! Her sanity? Host John O’Hurley’s voice boomed with classic game show boisterousness as he shouted, “Has she lost her mind?!” Ding! Other answers included “Her Children” and “Weight”-to which O’Hurley replied, “I guess.” In 2008, the same year that Britney Spears had been placed under a 5150 psychiatric hold after losing custody of her children amid a painful, tabloid-fueled public breakdown, a gaggle of Family Feud contestants took turns guessing at all the things she’d lost.

In 1961 a report was issued indicating Navy and Air Force interest in a lightweight bomb to replace existing weapons, but that both services had considerably different military requirements for such a weapon. B61 bomb casing MAPS Air Museum, North Canton, Ohio. Development A B61 bomb undergoing disassembly. According to the Federation of American Scientists in 2012, the roughly 400 B61-12s will cost $28 million apiece. As of 2020, it is undergoing a 12th modification. Basic weight is about 700 pounds (320 kg), although the weights of individual weapons may vary depending on version and fuze/retardation configuration. It has a streamlined casing capable of withstanding supersonic flight and is 11 ft 8 in (3.56 m) long, with a diameter of about 13 inches (33 cm). It is a Full Fuzing Option (FUFO) weapon, meaning it is equipped with the full range of fuzing and delivery options, including air and ground burst fuzing, and free-fall, retarded free-fall and laydown delivery. The B61 is of the variable yield ("dial-a-yield" in informal military jargon) design with a yield of 0.3 to 340 kilotons in its various mods. It is a low to intermediate-yield strategic and tactical nuclear weapon featuring a two-stage radiation implosion design.
