In this paper, we present a new method to simulate the signal of polarization-sensitive optical coherence tomography (for short, PS-OCT) by the use of the sphere cylinder birefringence Monte Carlo program developed by our laboratory. Using the program, we can simulate various turbid media based on different optical models and analyze the scattering and polarization information of the simulated media. The detecting area and angle range and the scattering times of the photons are three main conditions we can use to screen out the photons which contribute to the signal of PS-OCT, and in this paper, we study the effects of these three factors on simulation results using our program, and find that the scattering times of the photon is the main factor to affect the signal, and the detecting area and angle range are less important but necessary conditions. In order to test and verify the feasibility of our simulation, we use two methods as a reference. One is called Extended Huygens Fresnel (for short, EHF) method, which is based on electromagnetism theory and can describe the single scattering and multiple scattering of light. By comparison of the results obtained from EHF method and ours, we explore the screening regularities of the photons in the simulation. Meanwhile, we also compare our simulation with another polarization related simulation presented by a Russian group, and our experimental results. Both the comparisons find that our simulation is efficient for PS-OCT at the superficial depth range, and should be further corrected in order to simulate the signal of PS-OCT at deeper depth. © Copyright SPIE.

We propose and conduct both the rotating linear polarization imaging (RLPI) and Mueller matrix transformation (MMT) measurements of different biological tissue samples, and testify the capability of the Mueller matrix polarimetry for the anisotropic scattering media. The independent parameters extracted from the RLPI and MMT techniques are compared and analyzed. The tissue experimental results show that the parameters are closely related to the structural characteristics of the turbid scattering media, including the sizes of the scatterers, the angular distribution and order of alignment of the fibers. The results and conclusions in this paper may provide a potential method for the detection of precancerous and early stage cancerous tissues. Also, such studies represent the Mueller matrix transformation procedure which results in a set of parameters linking up the Mueller matrix elements to the structural and optical properties of the media. © 2012 World Scientific Publishing Company.

OBJECTIVES Objective evaluation of the impact of minimized extracorporeal circulation (MECC) on perioperative cognitive brain function in coronary artery bypass grafting (CABG) by electroencephalogram P300 wave event-related potentials and number connection test (NCT) as metrics of cognitive function. METHODS Cognitive brain function was assessed in 31 patients in 2013 with a mean age of 65 years [standard deviation (SD) 10] undergoing CABG by the use of MECC with P300 auditory evoked potentials (peak latencies in milliseconds) directly prior to intervention, 7 days after and 3 months later. Number connection test, serving as method of control, was performed simultaneously in all patients. RESULTS Seven days following CABG, cognitive P300 evoked potentials were comparable with preoperative baseline values [vertex (Cz) 376 (SD 11) ms vs 378 (18) ms, P = 0.39; frontal (Fz) 377 (11) vs 379 (21) ms, P = 0.53]. Cognitive brain function at 3 months was compared with baseline values [(Cz) 376 (11) ms vs 371 (14 ms) P = 0.09; (Fz) 377 (11) ms vs 371 (15) ms, P = 0.04]. Between the first postoperative measurement and 3 months later, significant improvement was observed [(Cz) 378 (18) ms vs 371 (14) ms, P = 0.03; (Fz) 379 (21) vs 371 (15) ms, P = 0.02]. Similar clearly corresponding patterns could be obtained via the number connection test. Results could be confirmed in repeated measures analysis of variance for Cz (P = 0.05) and (Fz) results (P = 0.04). CONCLUSIONS MECC does not adversely affect cognitive brain function after CABG. Additionally, these patients experience a substantial significant cognitive improvement after 3 months, evidentiary proving that the concept of MECC ensures safety and outcome in terms of brain function. © The Author 2014.

Tokyo-based startup Minimal Technologies today announced that it has secured a business partnership with Recruit, the Japanese web services conglomerate best known for its eponymous job placement service. Recruit will use the startup’s multilingual website localization service in a bid to attract more non-Japanese visitors to its sites ahead of the international tourism influx that will be created by the 2020 Tokyo Olympics. The alliance with Recruit is sure to raise the domestic profile of WOVN, launched in June 2014. As Minimal Technologies co-founder Jeff Sandford explains, Recruit’s adoption of the service will likely entice others to follow. “If a large company in Japan is not using your service, it’s very hard to get other large companies to take the plunge,” Sandford explains. “Having Recruit show their confidence in us will be great for getting other large corporations to use WOVN as well, and that will lead to other smaller companies utilizing our service.” Recruit will roll out WOVN widgets, capable of translating websites into the top 27 most popular languages on the web, across 12 of its domains to start with. Additional Recruit sites will receive the service down the road. In addition to its new business alliance, Minimal Technologies is also releasing a beta of its backend service WOVN++ today. WOVN is currently a Javascript frontend code, hidden in a website’s HTML header. The backend version will improve SEO results for multi-language searches, as it creates a small library on the server and switches the language before it goes to the browser itself. If your website (say is in English but you want to offer Japanese, you can have WOVN++ automatically generate unique URLs ( or This way, search engines can pick up on the translated language – not just the original. “We can make a lot of choices for you, as there’s a lot of busywork that we can take care of – that’s our focus in everything we’re creating,” Sandford says. “Changing paths and subdomains usually requires new routing inside the application, but WOVN++ stays outside of the application server as much as possible, and it doesn’t change your code.” For enterprise users who want to have complete control over their own data, WOVN++ also allows them to host the translated content on their own servers instead of the startup’s. Both WOVN and WOVN++ have free and paid tiers, but Sandford hints that the latter may become a premium-only service in the future. Between October 2014 and now, WOVN’s total user base has grown from 1,000 to more than 4,500. Minimal Technologies raised 31 million yen (US$250,000) from Incubate Fund over two seed funding rounds last spring and summer.

Tokyo-based Minimal Technologies, the startup behind multilingual website localization service, has raised JPY 130 million (US$1.1 million) in pre-series A funding. Opt Ventures, the investment subsidiary of Japan’s largest e-marketing company, led the round, with Nissay Capital contributing. Just two months ago, Minimal Technologies announced a business partnership with Japanese job placement and internet services giant Recruit. That deal will see the startup’s WOVN widgets added to the company’s websites, increasing visibility for foreign visitors ahead of the 2020 Tokyo Olympics. WOVN’s widgets provide customizable website translations for the 27 most popular languages on the web. “We’re still working with Recruit and on schedule, but they have not rolled out WOVN on any sites yet,” Minimal Technologies co-founder Jeff Sandford tells Tech in Asia. “As is normal when working with a company the size of Recruit, we are at still at the preparation stage. Going by the schedule, they will start to use WOVN this fall.” In addition to the startup’s partnership with Recruit, Minimal Technologies also unveiled a beta of its backend service WOVN++. It improves SEO results for searches in different languages by allowing a search engine to see the translated version of a website, not only the original. If you’re running an English website with WOVN++ that supports Japanese, for example, someone searching for it via Yahoo Japan will be able to see results for the Japanese iteration. It also generates custom, language-based URLs and allows enterprise users to host translated data on their own servers. “We’re working with a number of websites, large and small, to improve the service and bring it out of beta,” he adds, indicating that WOVN widgets have been adopted by more than 4,500 websites internationally so far. Today’s funding will be used to hire new talent, specifically developers. The startup previously raised JPY 31 million (US$280,000) in seed funding from Incubate Fund last year.

Here’s our newest round-up of the featured startups on our site this week. If you have startup tips or story suggestions, feel free to email us. Enjoy this week’s list! Tweezar wants to make it easier for diamond traders to communicate with end users in a much more transparent manner. The startup’s 3D-printed rectangular gizmo allows merchants simply take the diamond stone, slide it into the device, and click start. Within 20 seconds, the device will take a high-definition image of the stone. Merchants then use the Tweezar app on their smartphone, which has embedded optical character recognition (OCR) technology, allowing them to scan the diamond’s certificate. After all parameters are complete, both the high-definition images of the diamond as well as its accompanying certificate will be uploaded on ecommerce sites such as Ebay. MotionElements is a marketplace for stock video, animations, and after effects. The startup aims go beyond being just a marketplace for video creators, but to build a place where creators in the world can connect, create, earn, and learn. Operating in Singapore and Malaysia, CatchThatBus lets users book cross-country trips between both countries through a website or its iOS, Android, or Windows apps. Through the mobile apps, users can also view real-time information on schedules and seat availability. PopSlide is a lock screen reward-based advertising product from Singapore-based tech firm Yoyo. Users can gather points by swiping their lock screens to look at mobile ads. When ready, they can redeem points for free mobile credit. Developed by Tokyo-based Minimal Technologies, multilingual website localization service allows visitors to translate a website one HTML tag at a time, offering both machine translation and “premium” human translation. Bangalore-based Zivame is the country’s largest online lingerie retailer. From everyday underwear to sexy lingerie, as well as maternity, plus size and bridal lingerie, the startup brought an array of intimate wear for women online. Orders made on Zivame were also delivered discreetly – the outer package bears no insignia that might let delivery boys know there’s lingerie inside. Lamplight Analytics provides social media insights to brands. Its tools work not just in English, but also in Cantonese, Mandarin, Japanese, Korean, Malay, and Bahasa Indonesia. Bangalore-based startup Reverie has an answer to one of the biggest barriers for internet and mobile businesses in India: language. The startup has an application programming interface (API) that an app or portal can plug in to deliver its content in over 50 languages. Spa Monkeys is a quality control service and marketplace for the spa, beauty, and wellness industry in Asia. The platform only databases high-quality merchants and products, so whenever someone in Hong Kong goes to a gym, hair salon, or spa, and sees a Spa Monkey logo on the door — they know the business will not pressure them into buying packages, is well documented, and has good customer service. Ksubaka wants to reinvent advertising in Asia in a way that will most certainly keep consumers engaged with brands: through gaming kiosks. Touchscreen kiosks called “PlaySpots” are built and then strategically located in stores – right where consumers are making purchasing decisions. Many of the games offer rewards and carry an offline-to-online component (O2O). CloudSwyft upends the traditional hiring system for enterprises. Instead of asking applicants to talk about their skills, it will have them perform tasks. Using CloudSwyft, recruiters can choose a lab environment (Windows Server, Linux, Java, C#, etc.), drag and drop checkpoints or practical exercises, set scoring, save and publish, then assign to a job candidate. When completed, the employer can view the results right away. Creative technology startup Octagon made waves last month when it introduced a locally-manufactured virtual reality (VR) headset. Users can attach a mobile phone to the screen to experience virtual-reality like immersion. The startup also offers its own VR content to go with the headset: a collection of 360 degree photography of landscapes and historical sites from around the world. Toreta wants to solve restaurants’ reservation scheduling problems. It is available as an iPad app that takes restaurant employees through a customer call from start to finish. We’re now gearing up for our 10th edition, Tech in Asia Tokyo 2015, happening 8 and 9 September in Tokyo.
