Ancillary costs that increase, which impact gross margin, but the single largest has to do with volumes, volume degradation. Other criteria of the specified system, to which coherentists frequently appeal, are similarly unable to solve the specification problem. Since coherence with a set of beliefs is a test of truth, truth cannot consist in correspondence. Demand was stable for esthetic and opthalmic lasers. For example, when you search for a film, we use your search information and location to show the most relevant cinemas near you. If it is false, some other proposition about how many sentences Austen wrote that day is true.
The answer is to work on coherent writing. Is it mainly still in the one to three kilowatts or is that starting to spread to higher powers, a couple firms have introduced higher power lasers. Samsung continues to dominate the mobile display market with roughly a dozen other firms trying to close the gap. Question: Once I train my breathing to the rate of 5 cycles in approximately 1 minute, will it remain trained? Nikolay Todorov -- Longbow Research -- Analyst Okay, understood. Now, because particles can have more to them than just position, we can do the same thing with spin to the mix. A version which holds that truth is coherence with the beliefs of an omniscient being is proof against the objection. The risk associated with China has increased over the past quarter as we learn more about the evolving underlying situation, particularly in their domestic challenges.
Paul Thagard is the author of the first of two recent new arguments against the coherence theory. The increase is related to large collections that occurred in early January 2019, rather than in December of 2018. Coherentists who do not believe that the specified set is the set of propositions believed by an omniscient being are committed to rejection of the principle of bivalence since it is not the case that for every proposition either it or a contrary proposition coheres with the specified set. The correspondence theory, in contrast, states that the truth conditions of propositions are not in general propositions, but rather objective features of the world. John Ambroseo -- Chief Executive Officer, President, and Director Yeah, I think the thing to bear in mind with a number of these applications, and I think this is true for the industry, not just Coherent, is that we're playing the role -- I shouldn't say. Advocates of the correspondence theory believe that a belief is at least most of the time ontologically distinct from the objective conditions which make the belief true.
What are and incoherent radiation? If the specified set is a set actually believed, or even a set which would be believed by people like us at some limit of inquiry, coherentism involves the rejection of realism about truth. I assume so, but -- Kevin Palatnik -- Chief Financial Officer and Executive Vice President Your assumption is correct. I suggested a middle ground between long-range strategic planning and the need for immediate strategy, execution, learning and nimbleness. It's not a big enough piece of the business to cast a swing vote, but I would say, in general, three of the four end markets are doing well. I would like to remind everyone that some information provided during this call may include forward-looking statements, including, without limitation, statements about Coherent's future events, anticipated financial results, business trends, and the expected timing and benefit, if any, of such trends. He also says this is helpful in teleportation.
Sounds like a science fiction book to me. We're just not going to go into the verticals. Bret DiMarco -- Executive Vice President and General Counsel Thank you, Connor, and good afternoon, everyone. I was trying to discern between your two segments there. I think the downturn that everybody's pointing to really is capacity expansion because we were on a memory craze for several years, and that has righted itself based on how memory pricing has changed just in the last two or three quarters. How about just a housekeeping question?.
An every day description of entanglement would be the following: A set of twins, a boy and a girl, have moved in opposite directions, one lives in California the other in New York. John Ambroseo -- Chief Executive Officer, President, and Director Sure. The Chinese government has to strike a delicate balance between reigning in debt and providing stimulus, which has been previously effective in driving demand for big-ticket items like autos and appliances. Without being specific around the timing of any orders with any specific customer, I would say the level of activity remains to be positive. More importantly, a coherence theory of truth does not follow from the premisses.
If, however, the coherence theorist holds that the truth of the law of non-contradiction depends on its coherence with a system of beliefs, and it were supposed to be false, then propositions cannot cohere or fail to cohere. While there are myriad tools, systems, methods and models of strategic planning, not all of them address all of these foundational questions. This account of coherence is unsatisfactory for the following reason. We also use this information to show you ads for similar films you may like in the future. If coherence is consistency, the coherence theorist would have to claim that both propositions are true, but this is impossible. Any more color you can give us and do you think that's going to continue? Coherence is, in the end, a matter of perception.
Answer: Yes, caffeine stimulates sympathetic emphasis resulting in a relatively higher sympathetic bias, thus making it more challenging to achieve balance. Operator Your next question comes from the line of Blayne Curtis with Barclays. This is the case since there is no guarantee that a perfectly coherent set of beliefs matches objective reality. Sometimes coherence theorists maintain that the specified system is the most comprehensive system, but this is not the basis of a successful response to the specification problem. The distance over which the coherence persists is called coherent length.
Question: How is this any different than just breathing slowly? John Ambroseo -- Chief Executive Officer, President, and Director Sure. Modifying one's breathing is not unlike modifying one's posture. John Ambroseo -- President and Chief Executive Officer Thanks, Bret. John Ambroseo -- Chief Executive Officer, President, and Director I think that the customers will continue to keep an aggressive posture on inventory as a cash conservation method, and we're in position where we can supply on relatively short notice. Any conversation around using any form of annealing would really be on refresh rates, and being able to surpass what is currently in the market.
