Documents that express an opinion abound, especially in the so-called web 2.0 era of social media and social networking. Jae-Young Chang of the Department of Computer Engineering at Hansung University, in Seoul, South Korea, suggests that there is a need to find ways to summarize their contents for a wide range of applications.

Augmented reality (AR), virtual reality (VR), and mixed reality (MR) technology open new possibilities across many fields. However, high-quality extended reality (XR) applications are computationally heavy in terms of computer graphics, which means that they do not run smoothly on inexpensive and easy-to-use XR devices such as VR/AR headsets and smartphones, because their GPU computing capacity is limited.

A point set registration problem is a task using two shapes, each consisting of a set of points, to estimate the relationship of individual points between the two shapes. Here, a “shape” is like a human body or face, which is similar to another body or face but exhibits morphological diversity. Taking the face as an example: the center position of the pupil of an eye varies depending on individuals but can be thought to have a correspondence with that of another person. Such a correspondence can be estimated by gradually deforming one shape to be superimposable on the other. Estimation of the correspondence of a point on one shape to a point on another is the point set registration problem. Since the number of points of one shape could be millions, estimation of correspondence is calculated by a computer. Nonetheless, up to now, even when the fastest conventional method was used, it took a lot of time for calculation for registration of ca. 100,000 points. Thus, algorithms that could find a solution far faster without affecting accuracy have been sought. Furthermore, preliminary registration before automated estimation was a prerequisite for the conventional calculation method, so algorithms that do not need preliminary registration are desirable.

The Raspberry Pi is putting a cherry on top of its 8th anniversary cake by offering its popular top-of-the-line computer module for just $35. It’s a remarkable offer for a company that thrust itself onto the computer scene in 2012 with a credit-card sized Raspberry Pi 1 that featured a 700MHz ARM11 processor and 256MB of RAM. The price back in 2012: the same $35.

The World Health Organization has launched a new easy-to-access, digital version of its Model list of Essential Medicines (EML). The move will revolutionize the way this core WHO reference tool is used.
More than 150 countries currently use the WHO list to work out which medicines best meet their national health contexts and priorities, so they can compile their own national essential medicines lists.
Essential medicines are those that satisfy the priority health care needs of a population. They are the medicines that need to be available in a functioning health system at all times, in appropriate dosage forms, of assured quality, and at prices individuals and the community can afford.
Keeping up-to-date lists of the most important medicines a country needs is key to achieving health for all in a sustainable way.
Since 1977, the WHO list has been revised every 2 years (most recently in 2019) by a group of experts and published in print or PDF formats. It includes information about available dose forms and strengths; specifications as to who should take a medicine; what conditions a medicine can treat and how it should be taken, as well as details about the clinical evidence supporting recommendations being made.
The new electronic version brings the traditional EML to smartphones and computer screens in a comprehensive, freely accessible, online database. Instead of flicking through pages of information, users can search by simply clicking on the name of a medicine, for example, or a health issue. They can also make their own customized lists by exporting the list – in full or in part – into an Excel or Word version.
The electronic EML is the latest step in WHO’s effort to harness digital technologies to drive improvements in global public health, and advance progress towards universal health coverage.
