Efficient and Sustainable Transplutonium Isotope Production: A New Diagnostic Approach

Posted by in categories: computing, military, nuclear energy, space, sustainability

In this study, a novel rapid diagnostic method was developed for optimizing the production of transplutonium isotope through high flux reactor irradiation. The proposed method was based on the concept of “Single Energy Interval Value (SEIV)” and “Energy Spectrum Total Value (ESTV)”, which significantly improved the production efficiency of isotopes such as 252Cf (by 15.08 times), 244Cm (by 65.20 times), 242Cm (by 11.98 times), and 238Pu (by 7.41 times). As a promising alternative to the traditional Monte Carlo burnup calculation method, this method offers a more efficient approach to evaluate radiation schemes and optimize the design parameters. The research discovery provides a theoretical basis for further refining the analysis of transplutonium isotope production, leading to more efficient and sustainable production methods. Future studies could focus on the implementation of energy spectrum conversion technology to further improve the optimal energy spectrum.

The production of transplutonium isotope, which are essential in numerous fields such as military and space technology, remains inefficient despite being produced through irradiation in a high flux reactor. Past studies on the optimization of transplutonium isotope production through irradiation in a high flux reactor have been limited by the computational complexity of traditional methods such as Monte Carlo burnup calculation. These limitations have hindered the refinement of the evaluation, screening, and optimization of the irradiation schemes. Hence, this research aimed to develop a rapid diagnostic method for evaluating radiation schemes that can improve the production efficiency of isotopes such as 252Cf, 244Cm, 242Cm, and 238Pu. The outcome of the study showed great potential in advancing the production of transplutonium isotope, which have numerous applications in fields such as military, energy, and space technology.

Algorithms don’t understand sarcasm. Yeah, right!

Posted by in categories: computing, information science

Sarcasm, a complex linguistic phenomenon often found in online communication, often serves as a means to express deep-seated opinions or emotions in a particular manner that can be in some sense witty, passive-aggressive, or more often than not demeaning or ridiculing to the person being addressed. Recognizing sarcasm in the written word is crucial for understanding the true intent behind a given statement, particularly when we are considering social media or online customer reviews.

While spotting that someone is being sarcastic in the offline world is usually fairly easy given facial expression, and other indicators, it is harder to decipher sarcasm in online text. New work published in the International Journal of Wireless and Mobile Computing hopes to meet this challenge. Geeta Abakash Sahu and Manoj Hudnurkar of the Symbiosis International University in Pune, India, have developed an advanced sarcasm detection model aimed at accurately identifying sarcastic remarks in digital conversations, a task crucial for understanding the true intent behind online statements.

The team’s model comprises four main phases. It begins with text pre-processing, which involves filtering out common, or “noise,” words such as “the,” “it,” and “and.” It then breaks down the text into smaller units. To address the challenge of dealing with a large number of features, the team used optimal feature selection techniques to ensure the model’s efficiency by prioritizing only the most relevant features. Features indicative of sarcasm, such as information gain, chi-square, mutual information, and symmetrical uncertainty, are then extracted from this pre-processed data by the algorithm.

Meta’s big vision for face computers might be better than Apple’s

Posted by in categories: computing, futurism

And it’s also about seven times the price of the Quest 3, Meta’s current answer to the Vision Pro. It’s not as flashy as the Vision Pro, but right now you can do a lot more with it. Meta CEO Mark Zuckerberg was eager to point that out in his impromptu review of Apple’s headset. Meta’s strategy is focusing on what you can do now, and doing that gives people a reason to stick around. If they stick around, they’ve inherently bought into your idea of the future.

It’s too early to say how Apple’s tried-and-true approach will pan out. But a common complaint I’ve seen from Vision Pro buyers is they don’t know what to do with it besides watch movies. It’s also too early to say whether Meta glasses users will stick around long term. (They certainly didn’t for the Ray-Ban Stories.) But we do know one thing: at the end of his Vision Pro review, Zuckerberg said the Ray-Ban Meta Smart Glasses sales have far exceeded his hopes.

Quantum Breakthrough: New Method Preserves Information Against All Odds

Posted by in categories: computing, quantum physics

Add a dash of creamer to your morning coffee, and clouds of white liquid will swirl around your cup. But give it a few seconds, and those swirls will disappear, leaving you with an ordinary mug of brown liquid.

Something similar happens in quantum computer chips—devices that tap into the strange properties of the universe at its smallest scales—where information can quickly jumble up, limiting the memory capabilities of these tools.

That doesn’t have to be the case, said Rahul Nandkishore, associate professor of physics at the University of Colorado Boulder.

Infleqtion Unveils Quantum Roadmap for Quantum Sensing, Software and Computing Products

Posted by in categories: business, computing, engineering, particle physics, quantum physics

Infleqtion is unique amongst quantum companies due its participation in so many different segments of the quantum computing industry including quantum components, quantum computers, quantum software, and quantum sensors. This strategy of a broad product portfolio provides both advantages and disadvantages for a company. The potential advantages include achieving synergy between different product areas with the neutral atom, atomic prism, photonic, software, and other technologies they have developed over the years. It also brings some diversity in the revenue streams because some products will provide early revenue while others might take a few years of development before they can make a revenue contribution. The potential disadvantages could include execution risks if the engineering resources are spread too thin. Also, there may be different sets of customers and sales channels for the different product lines which can increase the complexities of managing a sales force, calling on customers, and generating new business.

Nonetheless, Infleqtion has made some interesting announcements in the past few months. In 2023 alone, the Quantum Computing Report by GQI ran 17 different stories that included Infleqtion. This week they hosted a webinar to discuss their product roadmaps for sensors, software, and computing. The highlight of the webinar was the announcement of their quantum computing roadmap. In this article, we will cover their plans for quantum computing, but first we will start with the progress they talked about in quantum sensors and quantum software and then discuss quantum computing afterwards.

Infleqtion’s discussion of sensor products included ones named Tiqker, Sqywire, and eXaqt. Tiqker is a small form factor ultra-accurate clock intended for use in navigation, data centers, and communication networks. The company asserts that this clock is 100X more accurate than cesium beam atomic clocks and 100,000X more accurate than a crystal oscillator. In navigation applications it can be used in GPS-denied environments and in communication networks it can help increase bandwidth and reduce latencies due to the more precise clocking of the data signals. The company mentioned that they are partnering with a large company for use of Tiqker in data center applications and that Tiqker is now available for pre-order. Sqywire is an ultra-sensitive radio frequency (RF) receiver that senses RF signals with Rydberg state atom-based sensing. It can be used installed of a classical antenna and provides high sensitivity, lower power, and ultra-wide bandwidth in a form factor.

Voltage Control over Magnons

Posted by in categories: computing, materials

Researchers have demonstrated that magnetic spin waves called magnons can be controlled by voltage and thus could operate more efficiently as information carriers in future devices.

Magnonic devices are being developed to transmit signals, not with electrons, but with magnons—traveling waves in the magnetic ordering of a material. New work provides one of the missing elements of the magnonics toolbox: a voltage-controlled magnon transistor [1]. The device is made up of a magnetic insulator sandwiched between two metal plates. The researchers show that they can control the flow of magnons in the insulator through voltages applied to the plates. The results could lead to more-efficient magnonic devices.

A magnon can be imagined as a row of fixed magnetic elements, or “spins,” that tilt and rotate their orientations in a coordinated pattern. This “spin wave” can carry information through a material without involving the movement of charges, which can cause undesirable heating in a circuit. Magnonics—though still in its infancy—is a potentially energy-efficient alternative to traditional electronics, says Xiu-Feng Han from the Chinese Academy of Sciences. The challenge right now for the magnonics field, he says, is developing practical versions of the four basic components of a magnonic circuit: a generator, a detector, a switch, and a transistor.

Scientists Create World’s First “Quantum Semiconductor”

Posted by in categories: biotech/medical, computing, mobile phones, quantum physics

Semiconductor devices are small components that manage the movement of electrons in contemporary electronic gadgets. They are essential for powering a wide range of high-tech products, including cell phones, laptops, and vehicle sensors, as well as cutting-edge medical devices. However, the presence of material impurities or variations in temperature can interfere with electron flow, causing instability.

But now, theoretical and experimental physicists from the Würzburg-Dresden Cluster of Excellence ct.qmat—Complexity and Topology in Quantum Matter have developed a semiconductor device from aluminum-gallium-arsenide (AlGaAs). This device’s electron flow, usually susceptible to interference, is safeguarded by a topological quantum phenomenon. This groundbreaking research was recently detailed in the esteemed journal Nature Physics.

“Thanks to the topological skin effect, all of the currents between the different contacts on the quantum semiconductor are unaffected by impurities or other external perturbations. This makes topological devices increasingly appealing for the semiconductor industry. They eliminate the need for the extremely high levels of material purity that currently drive up the costs of electronics manufacturing,” explains Professor Jeroen van den Brink, director of the Institute for Theoretical Solid State Physics at the Leibniz Institute for Solid State and Materials Research in Dresden (IFW) and a principal investigator of ct.qmat.
