The glasses were developed by four guys; Dave Crosby, Owen Reading, Richard Taylor and Greg Storey, who found a common interest in self-adjustable glasses and in the process created a company to fulfill the goal of providing low cost eyeglasses to the millions of people the world over who cannot afford a traditional pair. Their secondary market is for people who could use adjustable glasses for other than general use purposes, such as reading, working on a computer, knitting, i.e. for people as they get older and find they have trouble focusing while performing different tasks.The Eyejusters, which come with detachable thumb-dials also come with a plastic case and special cleaning cloth. The cloth can be used to clean both sides of both lenses because the outer lens can be hinged down for easy access. The Eyejusters also offer UV protection, which has been incorporated to help prevent eye damage from the sun, another common problem in underdeveloped countries.Another interesting aspect of the adjustable glasses is that it appears with a little tweaking, they could be used to perform self exams in more developed countries. By adding a digital display, the wearer could work out their own prescription and send it to a company that sells traditional eyeglasses, sidestepping an expensive trip to an ophthalmologist. Two pairs of specs in one: Touch of finger changes prescription (Phys.org) — A new kind of eyeglasses is now available from a British company that allows the wearer to adjust the prescription anytime, anywhere, via small thumb-dials on the sides. Called, Eyejusters, the glasses make use of a technology called a Slidelens, which very aptly describes how these glasses do their magic. Each lens is actually two lenses that have slightly different shapes; turning the thumb-dial causes one lens to move slightly left or right and that changes the focal point for the wearer. The lenses are moved until the person doing the focusing finds the sweet spot; which is exactly how users focus a pair of binoculars.

Eyejusters solve both problems; when ordered, they come with an eye-chart that can be used to help discern if a person’s vision can be corrected with Eyejusters (the power range is from +4.5 to 0 D (positive) and 0 to -5.0 D (negative)) and to figure out which version they need (for near or far vision correction).

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. Journal information: Biology Letters (Phys.org)—A team of researchers working in Australia has found via DNA analysis, that the lack of genetic diversity in pygmy blue whales is due to natural causes, not because of whaling. In their paper published in the journal Biology Letters, the researchers, affiliated with a variety of institutions in Australia, describe their study of the whales and why what they learned may help save them. That is good news for the species, because it means their lack of diversity is not due to whaling, (which did reduce their numbers dramatically, along with other blue whales)—it is because they are still so new of a species. Also because they are now a protected species, the researchers believe that if they can mitigate other threats, such as different sorts of human pollution, the whales have a good chance of returning to their pre-whaling population. Australian blue whales now call Antarctica home © 2015 Phys.org Pygmy blue whales are a subspecies of blue whales and contrary to their name, are not really all that small. They average 24 meters in length compared to their bigger cousins, which average 28 to 30 meters in length.For many years marine biologists have assumed that the lack of genetic diversity found in pygmy blue whales living around the shores of Australia, was due to their numbers being cut due to whaling. Now it appears that is not the case. In this new effort, the researchers sought to better understand the history of the whales and how they wound up with so little diversity. To learn more, they obtained DNA samples from several specimens and then studied patterns of genetic mutations—that allowed them to see that the whales had all come from just a few individuals, a “founder group,” beginning around 20,000 years ago. After comparing the pygmy whale DNA with other blue whales living in other parts of the world, the team was able to ascertain that they had gotten their start as Antarctic blue whales.The researchers note that 20,000 years ago, the Earth was experiencing peak glaciation, which allowed blue whales (currently the largest animal on the planet) to travel to other places, one of which was, apparently Australia. But then the glaciers retreated, leaving those that had migrated to adapt to their new environment—they evolved into the pygmy blue whales that exist today. More information: Low genetic diversity in pygmy blue whales is due to climate-induced diversification rather than anthropogenic impacts, Biology Letters, DOI: 10.1098/rsbl.2014.1037AbstractUnusually low genetic diversity can be a warning of an urgent need to mitigate causative anthropogenic activities. However, current low levels of genetic diversity in a population could also be due to natural historical events, including recent evolutionary divergence, or long-term persistence at a small population size. Here, we determine whether the relatively low genetic diversity of pygmy blue whales (Balaenoptera musculus brevicauda) in Australia is due to natural causes or overexploitation. We apply recently developed analytical approaches in the largest genetic dataset ever compiled to study blue whales (297 samples collected after whaling and representing lineages from Australia, Antarctica and Chile). We find that low levels of genetic diversity in Australia are due to a natural founder event from Antarctic blue whales (Balaenoptera musculus intermedia) that occurred around the Last Glacial Maximum, followed by evolutionary divergence. Historical climate change has therefore driven the evolution of blue whales into genetically, phenotypically and behaviourally distinct lineages that will likely be influenced by future climate change.
Journal information: Proceedings of the National Academy of Sciences (Phys.org)—That there are universal patterns in the naming of colors across languages has long been a topic of discussion in a range of disciplines, including anthropology, cognitive science and linguistics. However, previous color term research has not applied an evolutionary framework to the analysis of these worldwide patterns. Recently, scientists at Yale University traced the history of color systems in language by applying phylogenetic methods across a large language tree. They not only validated the phylogenetic approach to culture, but also generated a precise history of color terms across a large language sample drawn from the Pama-Nyungan languages of Australia, and moreover provided evidence supporting the loss and, as had been previously known, gain of color terms in the evolutionary process.

That is, our perception of the world disposes us to talk about things in certain ways. For example, humans aren’t very good at smelling (compared to hearing or seeing), so it’s not surprising that we don’t have a lot of smell-based vocabulary. The same is true for color – the color terms that are most frequently named are (with some simplification) those that refer to regions of the color spectrum that are maximally perceptually distinct from one another. It’s therefore not surprising that different languages would end up with similar color inventories. Our work shows that those same principles are at work in the ways in which color terms drop out of use.Bowern notes that the study is relevant to a number of related disciplines, including anthropology, psychology and linguistics. “Color naming has been a central question of all these disciplines for over 100 years now,” she points out. “Color was an early battleground around the idea that perception might shape language, and language perception. In essence, the debate revolved around cultural relativity and cultural differences, and whether languages that lexicalize the world in ways that differ significantly from their major European and Asian counterparts might yield crucial insights into human evolution and prehistory. “There’s also been discussion about the role of material culture in leading to color naming elaboration,” she adds. “An interesting example is purple, which in English originally referred to a particular type of ink, and was only later generalized as a color term that could refer to things other than ink. Our work shows how insights from historical linguistics give us a better idea about how these issues interact.”The pap theory1,2 play a substantial role in the development of color term systems, further study from an evolutionary perspective can refine our understanding of the interaction of cognitive constraints and language change in shaping lexical system.”Perhaps an analogy with numbers would be useful,” Bowern suggests. “It’s not surprising that so many languages have a base ten system for counting, because the ease of counting on fingers and toes makes that a very salient choice. However, languages change over time through sound and word change, and so in many languages we find clear base ten systems being obscured.” In English, she illustrates the relationship between the words three and thirty isn’t as clear as the relationship between eight and eighty. “We thought the same might be true for color – that is, while there might be cognitive constraints that lead humans to name colors in a certain way, we would also expect regular principles of language, particularly semantic, to apply – and indeed, that’s what we find: The cognitive constraints provide a framework for the types of colors that tend to appear, but languages acquire and change their color words from many sources. In short, color terms undergo broadening and narrowing, as other words do – but they do so within a framework that constrains the organization of the system.” Fig. 3.

Haynie published in the Proceedings of the National Academy of Sciences, these being:tracking the evolution of color terms across a large language tree in order to trace the color systems historyvalidating phylogenetic approaches to culture and providing an explicit history of color terms across a large language sample when working with the Pama-Nyungan languages of Australiafinding alternative trajectories of color term evolution beyond those considered in the standard theoriesapplying Bayesian phylogenetic methods to data that bridges linguistics, cultural anthropology, and cognitive science”We had a lot of trouble gtting data for the languages, as well as interpreting the data we had,” Bowern tells Phys.org. “Since there’s no preexisting set of color term datasets for these languages, we had to create it from grammars, dictionaries and field notes.” Moreover, she adds, if a term wasn’t in the dataset, they had to determine if it was truly absent from the language – or if it simply was not recorded in their data. The researchers also ran into difficulty deciding if a word was truly a color term, as was the case with orange, which had to be excluded from their list of colors because too many instances of the term referred only to the fruit.”There is now a substantial body of literature on phylogenetic approaches to culture,” Bowern continues. (Phylogenetics is the study of evolutionary relationships among species, individuals or genes, as modeled on trees.) “It’s still somewhat controversial, but the critiques of phylogenetics outside of biology often focus on the differences between biological systems and other areas of change, such as in linguistics or culture.” That said, she points out that oftentimes these critiques overlook the degree of difference among biological evolutionary processes. “It’s uncontroversial that language changes; it’s also uncontroversial that languages aren’t organisms. The point is that from Darwin on, language and biology have had a long history of cross-pollination and co-inspiration.” New study reveals that prelinguistic infants can categorize colors Since the paper addresses the links between perception, language, and the categorization of the natural world, Phys.org asked Bowern if more detailed perception of the environmental color spectrum leads to corresponding terms (a structural evolutionary change in the ascending visual pathway), or if terminology comes first in agglutinative languages as a complex form combining a color with a function.”I assume that it’s driven by terminology,” Bowern says. “Remember that this is not about what can be perceived – people can perceive color differences that they don’t have words for, and perception varies between individuals even when the color lexicon does not. However, within terminological change, there might be several different ways that the change could proceed. Perhaps as a term becomes more specialized to a part of a color range, an additional term is analogically brought into the system. Or, conversely, as a term becomes analogically applied to color, another term’s range is contracted.” Bowern notes that the researchers did not find evidence in the Australian data for compound colors, such as light red.Another interesting question is the dissociation between color perception and language in color blindness. “This is a good illustration of why we should usually look at the population/language level, rather than at specific individual speakers. A language still contains a word for red and green, even if some fraction of the population cannot distinguish those colors. We still have a vocabulary for music, even though some people are tone deaf. However, one could imagine a hypothetical language or dialect where enough people are color blind that those colors come to be called by the same name – but that hasn’t happened in our data set.”Bowern’s research group currently has work-in-progress in several aspects of language change related to both Australian languages, and language documentation and change in other regions. Specifically, they’re investigating ways to use computer tools to produce sound and text-aligned recordings – that is, align a recorded story with and words in the corresponding transcription. “This is incredibly useful for language research,” she tells Phys.org. Bowern is also continuing with her work in describing Australian languages, which already has provided some surprises. “In working on Australian language trees we found that Australia has approximately 400 languages – far more than 250 languages as was previously thought.” Not surprisingly, then, the scientists used fairly standard techniques in phylogenetics to look at color terms to address these challenges. “We defined the problem as one in which we were comparing theories, and testing which of the theories were well-supported by our data,” she explains. “For example, we compared theories where languages only lost color terms to ones where they could only gain them, or where they could both gain and lose them.” They found that their data and models did not support either of the first theories, and moreover had to find ways to model our data that were computationally tractable: The number of possible parameters for computer models with seven color terms were more than could be calculated.

After refining their system, the researchers entered real-world data from a major earthquake that occurred in Amatrice Italy in 2016 and from the series of aftershocks that followed. The aftershocks were so unusual that earthquake experts gave them their own name: the Amatrice-Norcia seismic sequence. After running the system, the researchers found that it “issued statistically reliable and skillful space-time-magnitude forecasts” for the event.While the results are promising, the researchers are quick to point out that their system is still in the pilot stage, and thus, it is still unclear how well it might perform when used to predict aftershock patterns that occur after future earthquakes.

Earthquake forecasting during the complex Amatrice-Norcia seismic sequence, Science Advances (2017). DOI: 10.1126/sciadv.1701239AbstractEarthquake forecasting is the ultimate challenge for seismologists, because it condenses the scientific knowledge about the earthquake occurrence process, and it is an essential component of any sound risk mitigation planning. It is commonly assumed that, in the short term, trustworthy earthquake forecasts are possible only for typical aftershock sequences, where the largest shock is followed by many smaller earthquakes that decay with time according to the Omori power law. We show that the current Italian operational earthquake forecasting system issued statistically reliable and skillful space-time-magnitude forecasts of the largest earthquakes during the complex 2016–2017 Amatrice-Norcia sequence, which is characterized by several bursts of seismicity and a significant deviation from the Omori law. This capability to deliver statistically reliable forecasts is an essential component of any program to assist public decision-makers and citizens in the challenging risk management of complex seismic sequences. A damaged building at Accumuli by the Amatrice earthquake (August 24, 2016). Credit: Marco Anzidei Scientists have long sought forecasting methods for earthquakes, for obvious reasons—unfortunately, to date, little progress has been made despite hundreds of years of effort. Science has advanced one area of forecasting, however: aftershocks that occur after a major quake.It has been noted that aftershocks can occur in sequences that frequently follow a power series. Because of that, seismologists could make predictions of aftershocks based on the degree of severity of the preceding major quake. But, as the researchers note, there are exceptions—sometimes, aftershocks seemingly occur randomly. Occasionally, they even precede a large quake. It was these exceptions that the researcher sought to address with a new and improved earthquake prediction system.The system built by the team is called an Operational Earthquake Forecasting (OEF) system, and is based on three predictive models. The first two are models known as epidemic-type aftershock sequences (ETAS), which use clustering information to make predictions. The third was based on the short-term earthquake probability model (STEP), which, as its name implies, is math based.

The star has an effective temperature of nearly 3,000 K, luminosity of around 0.03 solar luminosities and a rotation period of 1.63 days.EPIC 204376071 was observed by NASA’s Kepler spacecraft twice during its prolonged mission known as K2. When the star was observed by Kepler for the second time, in late 2017, a group of astronomers led by Saul Rappaport of Massachusetts Institute of Technology (MIT) identified a single occultation-like event in the light curve of the object.The detected occultation lasted for about a day and what interested researchers the most was the fact that the event was extremely deep and quite noticeably asymmetric with an egress about twice as long as the ingress.”In this work, we report the discovery of a one-day-long, 80 percent deep, occultation of a young star in the Upper Scorpius stellar association: EPIC 204376071,” the astronomers wrote in the paper.The event blocked up to about 80 percent of the light for an entire day. Besides this one-day occultation and frequent flares, as well as low-amplitude rotational modulation, EPIC 204376071 turned out to be quiet for a total of 160 days of K2’s two observational campaigns.According to the paper, there are a few things that make the detected event unique. These are the continuous coverage with half-hour sampling of the flux, the very clearly mapped-out asymmetry in the occultation profile, and weak emission identified in the Wide-field Infrared Survey Explorer (WISE) 3 and 4 bands.The researchers concluded that such a deep eclipse with these properties cannot be explained by another star crossing EPIC 204376071. They assume that this unique, very deep, long dip in the lightcurve could be caused by orbiting dust or small particles. The second theory is that a transient accretion event of dusty material near the corotation radius of the star could be responsible for the observed occultation.”We have explored two basic scenarios for producing a deep asymmetric occultation of the type observed in EPIC 204376071. In the first, we considered an intrinsically circular disk of dusty material anchored to a minor body orbiting the host star. (…) Second, we considered a dust sheet of material of basically unknown origin, though we do assume that the source of the dust is in a quasi-permanent orbit about the host star,” the paper reads.However, the astronomers added that it is too early to draw final conclusions on which of the two hypotheses is true. More studies of EPIC 204376071 are needed, in particular, radial velocity measurements to search for evidence of an orbiting body, and adaptive optics observations to search for scattered light from disk structures or evidence of low-mass wide companions. An international team of astronomers has observed a deep, day-long asymmetric occultation in a recently detected low-mass star known as EPIC 204376071. In a research paper published February 21 on arXiv.org, the scientists detail their finding and ponder various theories that could explain such peculiar occultation. © 2019 Science X Network This document is subject to copyright.

Many physicists and computer scientists believe they will soon outperform traditional computers. Unfortunately, reaching that goal has proven to be a difficult challenge. Several big-name companies have built quantum computers, but none are ready to compete with traditional hardware just yet. These companies have, over time, come to use the number of qubits that a given quantum computer uses as a means of measuring its performance—but most in the field agree that such a number is not really a good way to compare two very different quantum computers. IBM is one of the big-name companies working to create a truly useful quantum computer, and as part of that effort, has built models that they sell or lease to other companies looking to jump on the quantum bandwagon as soon as they become viable. As part of its announcement, IBM focused specifically on the term “quantum volume”—a metric that has not previously been used in the quantum computing field.
