Here’s how it works, step by step: The transmitter chip is made of four hybrid silicon lasers. Light beams from the lasers each travel into an optical modulator. The modulator encodes data onto the beams at 12.5Gbps. The four beams are then combined and output to a single optical fiber, for a total data rate of 50Gbps. At the other end of the link, the receiver chip separates the four optical beams and directs them into photo detectors. The photo detectors convert data back into electrical signals.

Erikson’s Stages of Development  Erik Erikson, a German psychoanalyst heavily influenced by Sigmund Freud, explored three aspects of identity: the ego identity (self), personal identity (the personal idiosyncrasies that distinguish a person from another, social/cultural identity (the collection of social roles a person might play). Erikson’s psychosocial theory of development considers the impact of external factors, parents and society on personality development from childhood to adulthood. According to Erikson’s theory, every person must pass through a series of eight interrelated stages over the entire life cycle. Infant (Hope) – Basic Trust vs. Mistrust Toddler (Will) – Autonomy vs. Shame Preschooler (Purpose) – Initiative vs. Guilt School-Age Child (Competence) – Industry vs. Inferiority Adolescent (Fidelity) – Identity vs. Identity Diffusion Young Adult (Love) – Intimacy vs. Isolation Middle-aged Adult (Care) – Generativity vs. Self-absorption Older Adult (Wisdom) – Integrity vs. Despair

Persons who circumvent access controls in order to engage in noninfringing uses of works in these six classes will not be subject to the statutory prohibition against circumvention.

The purpose of the proceeding is to determine whether current technologies that control access to copyrighted works are diminishing the ability of individuals to use works in lawful, noninfringing ways.

Theories and Models of Learning for Educational Research and Practice. This knowledge base features learning theories that address how people learn. A resource useful for scholars of various fields such as educational psychology, instructional design, and human-computer interaction. Below is the index of learning theories, grouped in somewhat arbitrary categories.

Solutions to the world’s problems will never be found in textbooks.

Are you verbal/linguistic? Then you make sense out of the world through language and can use words effectively either speaking or in writing. When you make puns and tell stories, you exhibit this intelligence.Learning strategies: read material before going to lectures; take notes of what you hear and read; describe what you have learned to others; listen to what others have learned;write out the steps/instructions to a procedure or experiment;use crossword puzzles, puns and imaginary conversations as memory devices;use your verbal/linguistic knowledge to help you study. For example, if you are taking a course in music, make up a story based on what you hear.

Information literacy is a set of abilities requiring individuals to "recognize when information is needed and have the ability to locate, evaluate, and use effectively the needed information." 1

he researchers report their findings in the advance online publication of the Nature Cell Biology July issue. The cells in our bodies constantly sense their environment and respond appropriately. For example, if pathogens invade the body, cells will respond by generating an inflammatory environment to fight the pathogen. This is achieved by intricate molecular circuits within cells that sense and relay external signals and orchestrate the cellular response. Aberrant functioning of these cellular switch boards can lead to diseases including autoimmune disorders and cancer. In the study, an the scientists set out to better understand the molecular workings underlying inflammation. Inflammation, the body's primary line of defense against disease-causing microbes and parasites, is a highly complex and tightly regulated biochemical process involving a myriad of specialized cells communicating with each other through an arsenal of signaling molecules.

the enduring themes that emerge across contexts and times. These themes include the need to: negotiate educational beliefs in each situation; focus on the details of learning design; consider the importance of relevant and authentic tasks that enable learners to develop lifelong learning and earning capabilities; and accommodate shifting roles of both teachers and learners in a mutual comfort zone so that all participants benefit
