The system has two components: a pen and a receiver. The pen uses ordinary ink, and its regular size and weight makes writing feel natural. But the pen also contains an infrared sensor, which captures hand movements while writing. The receiver is clipped to the notepad or paper, and receives data from the pen through the pen´s ultrasonic transmitter. The receiver can store up to 50 pages of writing and pictures.The Mobile Digital Scribe comes with a USB cable which is used to connect the receiver to a PC. IOGEAR´s handwriting recognition software translates notes into text and sketches into JPEGs, which can be saved and edited. Text can be shared via JPEG format through e-mail or instant messaging.The Mobile Digital Scribe can also be connected to a PC while the user is writing, and handwritten text and drawings will be displayed automatically on the computer screen.The technology can identify 12 languages, including Italian, Swedish, Chinese, and Russian. IOGEAR plans to target the system at students as well as legal and medical professionals. Instead of carrying laptops to class and meetings, individuals can use regular paper with the electronic pen and receiver, and upload their notes at home. The Mobile Digital Scribe is available for $130, and comes with IOGEAR´s limited one-year warranty.via: www.iogear.comlast_img read more

Panasonic preps for WiGig era of content exchange

first_imgThe demo shows a passenger transferring media from the tablet to a display mounted in the passenger seat. An exchange of content also takes place from the car’s computer over to the tablet; the passenger checks out auto information such as readings on tire pressure and battery capacity.Panasonic is one of the companies that have been participating in the WiGig Alliance of companies, an alliance making a big push to advocate a wireless gigabit standard and to promote a strong ecosystem of interoperable devices. Panasonic is on the Alliance’s board of directors, along with other big industry names such as Dell, Intel, Cisco, Broadcom, and Microsoft. The shared understanding among the Alliance companies is that the technology marketplace is no longer just about Internet connectivity but device connectivity, as more consumers own multiple devices and seek fast, efficient data transfers from one device to another. The Alliance is not new; it was formed back in 2009 but observers note that the time appears ripe to turn up the volume in promoting WiGig’s commercial growth. The Alliance has worked on a unified specification for 60 GHz wireless technologies, to make it possible for multi-gigabit wireless connectivity among PCs, handhelds and a range of devices under the umbrella of consumer electronics. A WiGig MAC specification was published in June last year. The standard is in draft stage with the IEEE as 802.11ad. Some technologists prefer to note the limitations as well as benefits to come; the wireless technologies will offer higher data rates than 802.11ac, but at short distances – and where walls, ceilings and other obstructions don’t hinder the path. A benefit of operating at 60 GHz is availability.According to the Alliance, “60 GHz is the ultimate complement to both 2.4 and 5 GHz. The 60 GHz band simply has much more bandwidth available (7-9 GHz of spectrum) vs. 83.5 MHz in the 2.4 GHz band, which enables much higher data rates.” The organization intends to provide a certification mark, which will show consumers that products have passed interoperability testing. Panasonic meanwhile is in the process of prototyping the WiGig-enabled SD card, which it aims to commercialize for vehicle usage in summer 2013. That seems to mesh with the Alliance prediction that it expects “wide availability” of WiGig-enabled devices in 2013. According to Ars Technica, the spec is still undergoing some fine-tuning at IEEE.

New model describes cognitive decision making as the collapse of a quantum

first_img Explore further Diagram of a state representation of a Markov and a quantum random walk model. In the Markov model, evidence (shaded state) evolves over time by moving from state to state, occupying one definite evidence level at any given time. In the quantum model the decision-maker is in an indefinite evidence state, with each evidence level having a probability amplitude (shadings) at each point in time.

The content is provided for information purposes only. © 2015 Phys.org But the Markov random walk theory, based in classical probability theory, runs into problems when confronted with the emerging research consensus that preferences and beliefs are constructed, rather than revealed by judgments and decisions. An international group of psychological researchers now suggests a new model called the quantum random walk (QRW) theory that specifically posits that preferences and beliefs are constructed rather than revealed by judgments and decisions, and they have published the results of an experiment that support this theory in the Proceedings of the National Academy of Sciences.By contrast with MRW, the new theory assumes that evidence develops over time in a superposition state analogous to the wave-like state of a photon, and judgements and decisions are made when this indefinite superposition state “collapses” into a definite state of evidence. It’s important to note that the researchers are not suggesting that the brain is a quantum computer; they specifically note that their report uses quantum dynamics only metaphorically.In the experiment, nine study participants completed 112 blocks of 24 trials each over five sessions, in which they viewed a random dot motion stimulus on a screen. A percentage of the dots moved coherently in a single direction. The researchers manipulated the difficulty of the test between trials. In the choice condition, participants were asked to decide whether the coherently moving dots were traveling to the left or the right. In the no-choice condition, participants were prompted by an audio tone simply to make a motor response. Then participants were asked to rate their confidence that the coherently moving dots were traveling to the right on a scale ranging from 0 (certain left) to 100 percent (certain right). The researchers report that, on average, confidence ratings were much higher when the trajectories of the dots were highly coherent. Confidence ratings were lower in the no-choice condition than in the choice condition, providing evidence against the read-out assumption of MRW theory, which holds that confidence in the choice condition should be higher.The QRW theory posits that evidence evolves over time, as in MRW, but that judgments and decisions create a new definite state from an indefinite, superposition-like state. “This quantum perspective reconceptualizes how we model uncertainty and formalizes a long-held hypothesis that judgments and decisions create rather than reveal preferences and beliefs,” the authors write.They conclude, “…quantum random walk theory provides a previously unexamined perspective on the nature of the evidence accumulation process that underlies both cognitive and neural theories of decision making.” More information: “Interference effects of choice on confidence: Quantum characteristics of evidence accumulation.” PNAS, published ahead of print August 10, 2015, DOI: 10.1073/pnas.1500688112AbstractDecision-making relies on a process of evidence accumulation which generates support for possible hypotheses. Models of this process derived from classical stochastic theories assume that information accumulates by moving across definite levels of evidence, carving out a single trajectory across these levels over time. In contrast, quantum decision models assume that evidence develops over time in a superposition state analogous to a wavelike pattern and that judgments and decisions are constructed by a measurement process by which a definite state of evidence is created from this indefinite state. This constructive process implies that interference effects should arise when multiple responses (measurements) are elicited over time. We report such an interference effect during a motion direction discrimination task. Decisions during the task interfered with subsequent confidence judgments, resulting in less extreme and more accurate judgments than when no decision was elicited. These results provide qualitative and quantitative support for a quantum random walk model of evidence accumulation over the popular Markov random walk model. We discuss the cognitive and neural implications of modeling evidence accumulation as a quantum dynamic system.center_img Certainty in our choices often a matter of time, study finds Citation: New model describes cognitive decision making as the collapse of a quantum superstate
 (2015, August 12) retrieved 18 August 2019 from https://phys.org/news/2015-08-cognitive-decision-collapse-quantum-superstate.html (Phys.org)—Decision making in an enormous range of tasks involves the accumulation of evidence in support of different hypotheses. One of the enduring models of evidence accumulation is the Markov random walk (MRW) theory, which assigns a probability to each hypothesis. In an MRW model of decision making, when deciding between two hypotheses, the cumulative evidence for and against each hypothesis reaches different levels at different times, moving particle-like from state to state and only occupying a single definite evidence level at any given point.

Astronomers conduct chemical investigation of globular cluster NGC 6723

first_img Globular clusters (GCs) are collections of tightly bound stars orbiting galaxies. Astronomers perceive them as natural laboratories enabling studies on the evolution of stars and galaxies. Given that GCs are relatively rare, as there are just over 200 such clusters so far identified in the Milky Way, the hunt for new objects of this type and studying them is essential in order to improve our understanding of our home galaxy.However, many known GCs still remain poorly studied, especially with regard to heavier elements. This is the case with NGC 6723—a GC about 12.5 billion years old located some 28,400 light years away in the constellation Sagittarius. Although this cluster has been studied photometrically in the past, its history of spectroscopic observations is unsatisfactory, leaving many uncertainties regarding its chemical composition.A team of astronomers led by Juliana Crestani of the Federal University of Rio Grande do Sul, Brazil, decided to change that. They have performed a detailed spectral analysis of NGC 6723 using high-resolution spectra for 11 RGB stars collected with the Magellan Inamori Kyocera Echelle (MIKE) instrument on one of the twin 6.5 Magellan telescopes, and with the Fibre-fed, Extended Range, Echelle Spectrograph (FEROS) at the MPG/ESO 2.2-meter telescope. This allowed them to investigate abundances of a variety of species, including light, alpha, iron-peak and neutron-capture elements in the selected sample of stars.”In the present work, we have obtained abundance estimates for variety of chemical species with a sample of 11 RGB stars,” the astronomers wrote in the paper.The research found a mean metallicity at a level of about −0.93, with a star-to-star spread of around 0.05 dex. The typical alpha enrichment was measured at approximately 0.39, which follows the trend of metal-poor and metal-intermediate globular clusters.The astronomers noted that the same trend was observed also for light metals, iron-peak, s/r-process elements and for the anticorrelation: Na-O and Mg-Al. The findings seem to suggest that the chemical enrichment of NGC 6723 is typical for metal-intermediate GCs.”The current findings further support the evidence that the chemical enrichment of NGC 6723 is more in line with metal-intermediate GCs and their lower metallicity counterparts, and it does not bring forward the prodrome of the metal-rich regime,” the researchers concluded.They added that the results put NGC 6723 right at the edge between the low and high metallicity regimes that correlate strongly with horizontal-branch morphology. By analyzing high-resolution spectra for 11 red giant branch (RGB) stars, astronomers have conducted a chemical investigation of the globular cluster NGC 6723. Results of the study, presented in a paper published June 24 on arXiv.org, offer more insights on the chemical enrichment of NGC 6723 and could be important to better understand chemical composition of globular clusters in general.
