Water shortage is one of the biggest challenges that humanity faces. Novel technologies to tackle the challenge of water scarcity are urgently needed. However, all the existing studies are based on bare fibers with diameter in the order of mm. This talk introduces a novel fog collection technology using microfibers fabricated by near-field electrospinning. The collection efficiency reaches a record high level. Systematic investigation reveals that the waterdrops are “visible” to fog droplets in the incoming air flow because of the relatively small size of the microfibers. Thus, the large waterdrops deflect the fog-carrying airflow to the satellite small waterdrops, which effectively intercept the fog droplets.

Most professions these days require more than general intelligence. They require in addition the ability to collect, analyze and think about data. Personal life is enriched when these same skills are applied to problems in everyday life involving judgment and choice. This course presents basic concepts from statistics, probability, scientific methodology, cognitive psychology and cost-benefit theory and shows how they can be applied to everything from picking one product over another to critiquing media accounts of scientific research. Concepts are defined briefly and breezily and then applied to many examples drawn from business, the media and everyday life.
What kinds of things will you learn? Why it’s usually a mistake to interview people for a job. Why it’s highly unlikely that, if your first meal in a new restaurant is excellent, you will find the next meal to be as good. Why economists regularly walk out of movies and leave restaurant food uneaten. Why getting your picture on the cover of Sports Illustrated usually means your next season is going to be a disappointment. Why you might not have a disease even though you’ve tested positive for it. Why you’re never going to know how coffee affects you unless you conduct an experiment in which you flip a coin to determine whether you will have coffee on a given day. Why it might be a mistake to use an office in a building you own as opposed to having your office in someone else’s building. Why you should never keep a stock that’s going down in hopes that it will go back up and prevent you from losing any of your initial investment. Why it is that a great deal of health information presented in the media is misinformation.

You’re sitting down for dinner with an old friend to catch up. You’re in the middle of sharing an anecdote when their phone dings. Their eyes shift to the screen, and they slide their device into their lap to send a reply.
Most of us have been on both sides of this scenario, and while it may seem harmless, these kinds of distractions during our everyday interactions can make people feel unheard or unimportant, fragment our attention, and hurt our relationships. On the other hand, research shows that active listening — putting your full focus on your conversational partner to truly understand their message — can help us anticipate problems, resolve conflicts, expand our knowledge and build trust.
Like any skill, active listening can be practiced and cultivated. Here are three key ways to become a better listener.

This course gives you easy access to the invaluable learning techniques used by experts in art, music, literature, math, science, sports, and many other disciplines. We’ll learn about how the brain uses two very different learning modes and how it encapsulates (“chunks”) information. We’ll also cover illusions of learning, memory techniques, dealing with procrastination, and best practices shown by research to be most effective in helping you master tough subjects.
Using these approaches, no matter what your skill levels in topics you would like to master, you can change your thinking and change your life. If you’re already an expert, this peep under the mental hood will give you ideas for turbocharging successful learning, including counter-intuitive test-taking tips and insights that will help you make the best use of your time on homework and problem sets. If you’re struggling, you’ll see a structured treasure trove of practical techniques that walk you through what you need to do to get on track. If you’ve ever wanted to become better at anything, this course will help serve as your guide.

Everyone experiences adversity and stress at some level, whether it’s the pressure to perform in school or work, relationship problems, financial difficulties, or simply the number of tasks to do in a short period of time. All stress isn’t bad, but chronic stress can take its toll on our minds, bodies, and behavior. Research has shown that people can learn and use specific resilience skills (such as optimistic thinking, relaxation strategies, choosing one’s attention) and positive routines (good sleep, scheduling in fun, and so on) in order to better manage stress, bounce back quicker after a setback, be more effective in their academic and vocational pursuits, develop stronger relationships with others, be physically and mentally healthy, and be satisfied with their lives overall. In short, resilience is ordinary magic and can be learned. It does not necessarily mean that you have to be born resilient or get lucky in life. The purpose of this course is to teach individuals the science behind becoming a resilient person. Stated simply, resilience is the ability to survive and thrive. Resiliency is not only about your ability to positively adapt in the face of adverse or challenging circumstances (that is, survive), but it is also about learning the positive skills, strategies and routines that enable you to live a happy, fulfilling, and meaningful life (in other words, thrive). This course gives you the permission to take care of yourself in order to effectively manage life stressors and do what matters most in life.
By the end of this course, you will have learned about the knowledge and skills that you can apply in your life now and in the future to be a resilient person.

Managers have tried various strategies and perks to boost employee engagement—all with little impact on long-term retention and performance. But now, neuroscience offers some answers. Through his research on the brain chemical oxytocin—shown to facilitate collaboration and teamwork—Zak has developed a framework for creating a culture of trust and building a happier, more loyal, and more productive workforce.
By measuring people’s oxytocin levels in response to various situations—first in the lab and later in the workplace—Zak identified eight key management behaviors that stimulate oxytocin production and generate trust: (1) Recognize excellence. (2) Induce “challenge stress.” (3) Give people discretion in how they do their work. (4) Enable job crafting. (5) Share information broadly. (6) Intentionally build relationships. (7) Facilitate whole-person growth. (8) Show vulnerability.
Ultimately, Zak concludes, managers can cultivate trust by setting a clear direction, giving people what they need to see it through, and then getting out of their way. In short, to boost engagement, treat people like responsible adults.

It needed to target different audiences for various business formats in the complex.To address these challenges, International Youth Culture Center identified market hotspots and strong IPs in 2014, and found that live TV shows, specifically "Running Man Brothers", were the hottest trend. By combining the conference center's highlights and the show's popularity, we successfully implemented our event marketing plan. After the program aired, International Youth Culture Center became a city-wide hotspot, achieving our marketing and budget targets.
