CAMBRIDGE, MA — Maybe you can’t tell a book from its cover, but according to researchers at MIT you may now be able to do the equivalent for materials of all sorts, from an airplane part to a medical implant. Their new approach allows engineers to figure out what’s going on inside simply by observing properties of the material’s surface. The team used a type of machine learning known as deep learning to compare a large set of simulated data about materials’ external force fields and the corresponding internal structure, and used that to generate a ...

According to computational complexity theory, mathematical problems have different levels of difficulty in the context of their solvability. While a classical computer can solve some problems (P) in polynomial time — i.e., the time required for solving P is a polynomial function of the input size — it often fails to solve NP problems that scale exponentially with the problem size and thus cannot be solved in polynomial time. Classical computers based on semiconductor devices are, therefore, inadequate ...

For text categorization, it is necessary to select a set of features(terms) with high discrimination by using feature selection. In text feature selection, Accuracy2（ACC2）treats terms with same absolute document rate difference but different discrimination equally, which is unreasonable. Existing improved methods (normalized difference measure（NDM）, max-min ratio（MMR）and trigonometric comparison measure（TCM）) based on ACC2 may confuse the importance of rare and sparse terms on account of challenge for parameter selection. To solve the problems, a research team led by Li Zhang published their new research on 15 February 2023 in Frontiers of Computer Science co-published ...

Safer cancer drugs are now one step closer after a new study led by UCL (University College London) researchers found the likely reason that some treatments damage the heart. Modern drugs can be very effective at treating cancer and have led to greatly improved survival rates. However, some cancer treatments can cause damage to the heart, or cardiotoxicity. This damage can present in a range of ways, from a slight change in the heart’s pumping ability to debilitating heart failure. But the ways in which these drugs cause damage ...

Innovating, i.e. the ability to find solutions to new problems or innovative solutions to known problems, it provides crucial benefits for the adaptation and the survival of human beings as well as for animals. What are the characteristics that make specific species or animals to be innovative? A study by the University of Barcelona has analysed this cognitive skill in ungulates, a group of mammals such as dromedaries, horses and goats, characterized by walking on the tip of their toes or hooves. The results show that those individuals that are less integrated ...

NAIROBI, Kenya, 20 April 2023_An international team of researchers, led by Africans, has fully sequenced the genome of a climate resilient bean that could bolster food security in drought-prone regions. The sequencing of the hyacinth bean or ‘lablab bean’ [Lablab purpureus] paves the way for wider cultivation of the crop, bringing nutritional and economic benefits, as well as much needed diversity to the global food system. The plant is native to Africa and is cultivated throughout the tropics producing highly nutritious beans, which are used for food ...

Large-scale circulation anomalies are a key factor in the transportation of water vapor and changes in climate. For tropical and subtropical regions, an atmospheric circulation field not only determines the characteristics of the weather situation but also influences the atmospheric circulation in the middle and high latitudes, as well as the global climate, through the transport of energy and angular momentum. At the same time, whilst lightning can serve as a global tropical “thermometer” and an indicator of water vapor in the upper troposphere, the driving role of the circulation situation for it needs to be further analyzed. In a paper recently ...

During photosynthesis, the green pigment chlorophyll in algae and plants absorbs most of the energy from incoming light. Chlorophyll gets excited and transfers this energy to the energy-harvesting protein complexes photosystem I (PSI) and II (PSII). However, some of this energy dissipates as heat or chlorophyll a fluorescence (ChlF). Changes in the environment or plant physiology that affect PSII also alter ChlF, which can therefore be used as a fast, sensitive, and non-destructive indicator of PSII status. Indeed, ChlF is a powerful tool for assessing multiple aspects of photosynthesis. Though ChlF measurements ...
