For most theories in physics, the order of operations has little impact on the result. When setting a dial to a certain ...

State machines can operate asynchronously for high-performance applications. This is ideal for I/O-bound tasks, such as in web servers or other concurrent environments, where you don't want a ...

For subcellular fractionation in periplasm/membrane/cytoplasm fractions, 50 mL of exponentially growing cultures were sedimented (3,260 × g, 4°C), and cells were resuspended in 20 mL of 20% sucrose/10 ...

Maria is either at home or in the office. She’s not at home. Where is she? You might wonder why I started with such an unpuzzling puzzle. But in solving it, you already used logic. You reasoned ...

Current neural prostheses can restore limb movement to tetraplegic patients by translating brain signals coding movements to control a variety of actuators. Fast and accurate somatosensory feedback is ...

Despite the importance of APs in ensuring the robustness and connectivity of many real-world networks, we still lack a deep understanding on the roles of APs in many complex networks. Can we design an ...

The influenza surface glycoprotein hemagglutinin (HA) is a potential target for antiviral drugs because of its key roles in the initial stages of infection: receptor binding and the fusion of virus ...

Naive T cell activation requires signaling by the T cell receptor and by nonclonotypic cell surface receptors. The most important costimulatory protein is the monovalent homodimer CD28, which ...
