Fast band structure computation using a new and efficient hHybrid method

Fast band structure computation using a new and efficient hHybrid method

Imagine you are an Uber driver and happen to pick up a material scientist or a physicist. What would be the first question you asked her/him? I could give the reader some examples based on my personal experience. This approach may seem naive or biased, but such questions may lead brilliant minds to dedicate themselves to the field. Two frequently asked questions are (i) how do people distinguish different phases of matter and (ii) what are the main challenges in material science? Of course, t...

Contribution of the thermal Hall effect to the anomalous Nernst and spin Seebeck effects

Contribution of the thermal Hall effect to the anomalous Nernst and spin Seebeck effects

Heat dissipation has been the most formidable challenge in information technology due to the continued increase in power dissipation, and it has hampered the development of charged-based electronic devices. Unlike purely charge-based systems, information devices encoded in magnetization states in spintronics are nonvolatile, which can reduce the power requirement for maintaining the data. Therefore, within a very short period of time, we have witnessed the remarkable success of spintronics to tr...

A paper-based test for tuberculosis diagnosis in developing countries

A paper-based test for tuberculosis diagnosis in developing countries

Scientists from Taiwan have developed a “paper” test for the diagnosis of tuberculosis infectionEarly diagnosis of tuberculosis (TB) allows patients to receive proper treatment and helps prevent the disease from spreading. However, in resource-limited areas, expensive test equipment and long wait times for results are obstacles to TB diagnosis and treatment. To overcome this problem, scientists report in ACS Sensors the development of a fast paper-based tuberculosis test that can be ...

Waste cold recovery using thermoelectric power generator

Waste cold recovery using thermoelectric power generator

Recovery of wasted cold energy by TEG The worldwide energy crisis has made people realize the importance of the waste energy recovery, and waste heat recovery has become a popular topic of discussion. However, waste cold is also common. For instance, liquefied gas storage is necessary for hospitals, the natural gas industry, the semiconductor industry, etc. In cryogenic engineering, liquid nitrogen is widely employed in the food, biotechnology, electronics and semiconductor manufacturing, and...

Which nature is legitimate?

Which nature is legitimate?

Riverfront redevelopment and urban agricultureWith the popularization of environmentalism, a resurgence of urban agriculture has been observed in Taiwan in recent years. NGOs, communities and even the government advocate for community gardens, home gardening, farmers’ markets, local food movements and shrinking the food footprint. The legitimacy of urban agriculture has thus been elevated and even gained the endorsement of official policy.Moreover, Taipei’s riverfront area, which was...

Probing the photovoltaic properties of silver-doped Cu(In, Ga)Se2 films by a nonvacuum solution process

Probing the photovoltaic properties of silver-doped Cu(In, Ga)Se2 films by a nonvacuum solution process

The ever-increasing demand for energy resources and sustainable development has promoted the growth of thin-film photovoltaic technology. Cu(In, Ga)Se2 (CIGS) solar cells have come to the forefront and are extensively considered a promising type of thin-film solar cell owing to their increased efficiency and potential for application in building-integrated photovoltaic systems. A schematic diagram of a CIGS solar cell is shown in Figure 1.Figure 1. Schematic diagram of a CIGS solar cell.It is we...

Different classes of statins have varying effects on reducing sepsis mortality

Different classes of statins have varying effects on reducing sepsis mortality

Sepsis, a pathogen-induced systemic inflammation that leads to organ dysfunction, remains a major public health problem. Each year, an estimated 20 to 30 million patients develop sepsis, and the annual incidence is still increasing in many countries. However, anti-infective therapy may not be sufficient for all sepsis patients and could give rise to antibiotic-resistant bacteria. Thus, strategies that can resolve inflammation or reverse immune paralysis associated with sepsis are intensively stu...

A genome-wide methylation study of coronary artery ectasia

A genome-wide methylation study of coronary artery ectasia

Approximately 38 million people die from noncommunicable diseases (NCDs) globally per year (Global status report on noncommunicable diseases 2014: Attaining the nine global noncommunicable diseases targets; a shared responsibility, 2014), and the most important contributing factor to these deaths is cardiovascular disease. Cardiovascular diseases have become the top 3 causes of death not only in Taiwan but also worldwide ("World Health Organization website [http://www.who.int/mediacentre/factshe...

Parental habits of betel quids chewing are dose-dependently associated with a risk of metabolic syndrome in offspring

Parental habits of betel quids chewing are dose-dependently associated with a risk of metabolic syndrome in offspring

Betel chewing, a socially important custom, is an addictive habit recognized as causing oropharyngeal and other cancers. Chewers of the chopped nuts of the Areca catechu palm, wrapped in piper betel vine leaves or flowers [‘betel-quids’], take the habit with them across the globe and currently number ~700 million [10% of the world population]. Addictive arecal alkaloids form carcinogenic nitroso-compounds during digestion, and many nitroso-compounds induce type 2 diabetes [T2DM] at l...

Pre-market trading and IPO prices

Pre-market trading and IPO prices

Underpricing is a known issue associated with initial public offerings (IPOs) throughout the world. This phenomenon has been observed in Taiwan. Traditionally, information asymmetry is used to explain the existence of tremendous IPO-related underpricing. Taiwan has a well-organized pre-IPO market. Trading information in a pre-IPO market can ameliorate the information asymmetry problem. However, underpricing levels remain high even if there is trading on a pre-IPO market. Information asymmetry th...
