Models and algorithms for analyzing complex networks are widely used in research and affect society at large through their applications in online social networks, search engines, and recommender systems. According to a new study, however, one widely used algorithmic approach for modeling these networks is fundamentally flawed, failing to capture important properties of real-world complex networks.

PUTRAJAYA: Prime Minister Tan Sri Muhyiddin Yassin said today any Cabinet member holding a new portfolio would require time to study the ministry and manage it well.
Commenting on women’s groups concerns with the Women and Family Ministry’s new appointments, Muhyiddin said he had briefed the newly-minted minister Datuk Seri Rina Mohd Harun about what to do to manage the ministry because she was new at the ministry.
“But it’s not that she is totally lack of experience. The new portfolio requires everyone to take more time to study,“ he said, adding that he had also told Rina to work closely with her deputy Datuk Siti Zailah Mohd Yusoff.
According to media reports, women’s rights groups had expressed their concerns over the appointment of Rina and Siti Zailah as the new minister and deputy minister mainly because their track records allegedly do not inspire confidence.
“What is important is not what her personal view is. What is important is what the government thinks about it and that she or whoever is in the ministry needs to understand,“ Muhyiddin said at a news conference after chairing the Economic Action Council (EAC) meeting here.
“Bear with us; we will manage it,“ he added. – Bernama

A world without robots is now almost inconceivable. Not only do they take on important tasks in production processes, they are also increasingly being used in the service sector. For example, machines created to resemble humans—known as androids—are helping to care for elderly people. However, this development conflicts with the preconception that senior citizens are rather hostile to technology and would be skeptical about a robot. A study by psychologists of Friedrich Schiller University Jena, Germany suggests, however, that older people are far less anxious and hostile regarding such ‘human robots’ than previously thought.

Commercial fast-charging stations subject electric car batteries to high temperatures and high resistance that can cause them to crack, leak, and lose their storage capacity, write engineers at the University of California, Riverside in a new study published in Energy Storage. To remedy this, the researchers have developed a method for charging at lower temperatures with less risk of catastrophic damage and loss of storage capacity.

As more robots make their way into society, it is important to consider the ethical and moral implications of having them complete tasks that can have a significant impact on people’s lives. If robots and machines are to become widely used in situations where they could seriously affect human lives, for instance by driving cars or giving elderly people the medication they need on a daily basis, developers should first consider the associated implications.

Colloidal quantum dot (CQD) solar cells have attracted considerable attention due to the advantages of being flexible and lightweight. Additionally, they are much easier to manufacture compared to commercial silicon solar cells in use today. Now, researchers report a novel technology capable of maximizing the performance of the existing CQD solar cells.
