Electron acceleration in the Van Allen radiation belts by fast magnetosonic waves

first_imgLocal acceleration is required to explain electron flux increases in the outer Van Allen radiation belt during magnetic storms. Here we show that fast magnetosonic waves, detected by Cluster 3, can accelerate electrons between ∼10 keV and a few MeV inside the outer radiation belt. Acceleration occurs via electron Landau resonance, and not Doppler shifted cyclotron resonance, due to wave propagation almost perpendicular to the ambient magnetic field. Using quasi-linear theory, pitch angle and energy diffusion rates are comparable to those for whistler mode chorus, suggesting that these waves are very important for local electron acceleration. Since pitch angle diffusion does not extend into the loss cone, these waves, on their own, are not important for loss to the atmosphere. We suggest that magnetosonic waves, which are generated by unstable proton ring distributions, are an important energy transfer process from the ring current to the Van Allen radiation belts.last_img read more

Finding creative ways to maintain campus bonds remotely

first_img Harvard faculty and staff talk about how they’re spending their time when there’s nowhere to go and no one to see Related Notes from the new normal Campus friend groups remain close, even if not geographically. So they’ve had to make adjustments to keep in touch. For some it was merely a matter of going remote with their regular weekly gathering; others discovered whole new reasons to get together. This is how three groups did it: one adapted, one reimagined, and one very recently crafted.An event adaptedSiva Emani ’21, a co-president of Harvard Dharma, began the Hindu group’s Zoom session with a check-in question, the typical starting point for their Friday evening social and worship gathering: “What’s the place you wish you could be at right now?”Of the more than 25 participants, many named spots on campus — the second floor of Cabot Library, IM soccer on Cumnock field. But several mentioned one in particular: the Dharma prayer space in Canaday Hall.,On Friday evenings during the school year, Harvard Dharma gathers in Canaday Hall for aarti, a worship session where light is offered to various deities, represented by physical idols. It begins with a member lighting a candle (diya), placing it atop a tray, and briefly circulating the flame before the idols, while the group sings “Om Jai Jagdish Hare.” The tray is passed to other members, each of whom can take a turn presenting the light to the idols and receiving a blessing.The challenge? How to turn aarti into a virtual ritual. Co-presidents Emani and Mit Patel ’21 pondered the options. Having each participant work with their own tray and candle might detract from the central, community focus. They decided that the members should take turns hosting aarti from their homes.,On April 3, Pranati Parikh ’21 sat in front of her family’s designated shrine. Her mother, Purvi Parikh, offered the aarti, while Pranati sang and her brother, Parth, played the drum (tabla). Once the devotional chant ended, Parikh’s mother walked the candle to the camera and waved her hand over it to direct the flame toward the screen, blessing the students tuning in.,Harvard Dharma has continued to tweak the ceremony. After the first Zoom aarti, for instance, it became apparent that it would sound much less chaotic if only the host’s singing was projected.Patel says that a silver lining to the new arrangement has been the chance to see the home traditions of Dharma members, and the specific idols that their families possess. And, Patel says, “It must be cool for parents to see their children continue their traditions in college.”After aarti, the group either does an activity or breaks up into small group discussions. A recent conversation focused on community and faith during the COVID-19 pandemic. Lowell House’s Varun Tekur ’22 expressed his gratitude for two values that Harvard Dharma and Hinduism encourage: “Calmness and community. Those values are emphasized in this time.”An event reimaginedEvening tea is a longstanding Thursday tradition at Lowell House. With residents scattered back to their hometowns, senior Meredith Pong came up with a plan to fill the void: In place of tea, she would serve up a baking tutorial.As assistant manager of the tea, Pong was the ideal candidate for this. In that role she led a handful of student bakers in preparing savory and sweet confections to feed 200 people each week. Last summer she interned at Ovenly bakery’s kitchen in Brooklyn, N.Y. She has taken Harvard’s “Science and Cooking” course, and binges on New York Times recipes and Bon Appétit videos.,And her reputation is sterling. Nina Zipser, a Lowell Faculty Dean, has emailed her with baking questions, most recently to ask why her custard curdled. (Pong suspects that “the heat was too high, causing all the water to evaporate and make the proteins curl up.”) She also has the endorsement of Beth Terry, Lowell House Administrator, who told Pong, “If I ever get married again, I want you to make that chocolate cake at my wedding.”Pong emailed the Lowell House list with her plan and received more than 30 enthusiastic responses. In her note, she suggested some flavors for an upcoming scones session: rosemary and currant, chocolate chip, blueberry and lemon, honey, cheddar chive, cheddar mustard — “really whatever people had in their pantry or could get their hands on.”Pong is conscious of choosing recipes that don’t require complex ingredients, since many students across the world are following stay-home guidelines. The first week she made chocolate chip cookies but went beyond basic recipe instructions. She discussed the importance of salt, how to properly cream butter and sugar, how to butter a pan, and how to achieve the desired chewy or crispy texture.On a recent Thursday, she convened a group for scones. Within minutes, Pong was fielding questions from Lowell peers on Zoom:“I don’t have heavy cream. Would replacing it with Greek yogurt or condensed milk work?” (Yogurt!)“For the rosemary, do I want the whole leaf or chopped pieces?” (Whole pieces!)Pong instructed viewers to squish butter between their thumbs and forefingers to a lima bean size. Then, let the dough rest in the refrigerator. “You want the flour to have time to hydrate and let all the gluten that’s been formed by the mixing relax. That way it’s less chewy.” Someone asked: “Can I see what your dough looks like?” prompting Pong to hold her bowl to the screen.,During tasks, the conversation went from upcoming housing day ideas to surveying how many people use TikTok. At one point, students brainstormed what they should bake in upcoming weeks. Someone suggested black bean brownies — not only healthy, “it’s the perfect apocalypse food.”Click here for the Ovenly Currant Rosemary Scones recipe.An event fully craftedBeyond those activities that have spun off existing ones, some have emerged on their own. Pforzheimer House residents have created many new online groups, and one of them caters to a very specific interest: Chinese costume dramas.Tutor Daniel Frim and senior Ying-ke Chin-Lee first began talking about East Asian cinema while eating Zinnekan’s waffles. Frim had hosted a final study break in Pforzheimer before students left campus — and the conversation they’d struck up seemed like the perfect interest to explore amid the pandemic diaspora.Frim and Chin-Lee emailed the Pforzheimer list inviting any and all to join them for Friday afternoon Zoom viewings. For the first week, Chin-Lee selected the first episode of the TV series “The Eternal Love” to share with her peers. In Zoom’s chat box, Chin-Lee mentioned that the drama is pretty cheesy, and knows it, to which Frim responded, “Cheesy is just what I need these days!”,To ensure coordinated viewing, Frim used the very high-tech method of a verbal countdown to signal when all viewers should press play on their YouTube video links.For a contrasting second viewing, Chin-Lee chose “Ashes of Love,” a more fantastical example. In the Flower Realm, a goddess gives birth to a daughter who is supposed to be prevented from falling in love. The plot thickens as this daughter is caught in a love triangle.,Afterward, Frim questioned Chin-Lee about elements that viewers not versed in Chinese costume dramas might miss. Before the discussion ended, she named a few favorites, including adaptations of two classic novels, 1994’s “Romance of the Three Kingdoms” and 1987’s “Dream of the Red Mansion.” Anyone looking for entertainment suggestions while at home should take note.

Closing the awareness gap and communicating the credit union difference

first_img“Credit unions are small and less secure than banks.” Credit unions do not have the federal insurance that banks do, which has caused misconceptions among consumers about credit unions for some time. Deposits with credit unions are insured by the National Credit Union Administration (NCUA), which offers the same type of coverage that banks have. Credit unions are held to the same regulations as banks and often times face more restrictions on their investments and loans. Through education and awareness, the goal is to help debunk misconceptions about credit unions for non-credit union members and to shed light on the truth about the credit union difference. Credit unions can take part in the effort to “close the gap” through every interaction with members and non-members alike.The entire webinar was recorded and is available for viewing by all registered subscribers of Engagement Builder at engage.pscu.com. “Credit unions have limited ATMs and branches, which translates into limited access to money.” Credit unions are cooperative in nature, meaning they work together to provide the best options for all members. Credit union members have access to shared banking networks without incurring fees and can utilize sister credit unions to perform banking activities at other locations. The options are not limited, just simply different from those offered by a traditional bank. “Credit unions are primarily for people in need.” Contrary to this belief, anyone can join a credit union. As mentioned above, each credit union has a commonality between its members. However, this does not mean that members have to be in need of financial, medical or professional support. center_img 158SHARESShareShareSharePrintMailGooglePinterestDiggRedditStumbleuponDeliciousBufferTumblr,Duane Hogg Duane Hogg is a digital strategist and credit union storyteller, creating content that compels Millennials to not only think but also act. In addition to content marketing for the Make … Web: www.pscu.com Details One-third of all U.S. citizens are currently members of a credit union. However, most have little to no idea what a credit union actually is and cannot correctly articulate how a credit union differs from a bank. For non-members, the lack of awareness is more acute.CUNA recently launched a Consumer Awareness Initiative to conduct nationwide research and help the industry create top of mind consumer awareness of and belief in credit unions as the best option in financial services. Myles Bristowe, vice president of marketing strategy and leader of Engagement Builder for PSCU, was invited to sit on the Consumer Awareness Advisory Group made up of a diverse cross-section of marketing leaders from various sectors of the credit union system.  The findings from the consumer research revealed a number of surprises and glaring inconsistencies in the way credit unions have been positioning themselves. These findings undoubtedly contribute to the sub-10 percent market share numbers credit unions are working to improve, despite having over 110 million U.S. members.On March 8, 2017, the Engagement Builder team hosted a webinar to share the provocative findings of the research with special guest speakers, Douglas Kiker, chief strategic communications officer for CUNA, and Graeme Trayner, vice president of the Brands and Communications practice at Greenberg, Quinlan and Rosner. Over 400 credit union leaders and marketers participate in the webinar.The research findings shared during the webinar revealed that credit unions are widely trusted by consumers and are best known for good rates, especially on car loans. However, there are several “myths” that consumers believe about credit unions:“I am not eligible to join a credit union.” The biggest difference between banks and credit unions is that a credit union serves a specific group of people or community. Criteria can include where someone lives, their profession, college affiliation or religious beliefs. With so many credit unions available today, non-members need to understand that eligibility guidelines are much broader than they might think. Consumers should conduct their own research to find a credit union that would be the best fit for their needs. last_img read more

Leaders gather in Cape Town for WEF on Africa

first_img1 June 2015The World Economic Forum’s 25th meeting in Africa, with the theme Then and Now: Reimagining Africa’s Future, takes place in Cape Town from 3 to 5 June.It will be the largest ever in the region, with more than 1 250 leaders from business, politics, academia, civil society and the media attending.The record levels of participation could be seen to reflect an optimism in the economic prospects of the region, according to the World Economic Forum (WEF), as well as an unprecedented commitment across all stakeholder groups to pursue public-private co-operation as a means of tackling the considerable challenges the region still faces.More than 90 senior government officials will attend and 83 leading international companies will be represented. “As befits Africa’s youthful population,” said the WEF, “the meeting will also boast a record 200 young leaders, drawn from the forum’s community of Global Shapers and Forum of Young Global Leaders, as well as the highest proportion of women leaders – at 270 woman leaders 25.8% – than ever before. In total, over 75 countries will be represented.”Lessons of the pastSpeaking on the eve of the gathering, Elsie Kanza, the head of Africa, World Economic Forum, said: “The occasion of our 25th meeting allows us an opportunity to see how far Africa has come economically, socially and politically since 1990. However, what this meeting is really about is looking forward, to see how we can channel the lessons of the past with the creativity, innovation and resourcefulness that comes from all stakeholders working together to solve Africa’s challenges in the present and future.”The WEF’s first meeting on Africa took place in October 1990.This year, the programme is built upon the three pillars: enabling markets, marshalling resources and inspiring creativity. It will feature high-level sessions on critical subjects such as migration, combating terrorism and harnessing Africa’s informal economy.Alongside the meeting, the Grow Africa Investment Forum, which runs from 2 to 4 June, will bring together leaders engaged in the forum-led Grow Africa food security initiative. Another high-level summit will take place focused on mobilising financing for cross-border infrastructure.There will also be several innovations, among them Community Conversations. These will be public debates based on the forum’s popular Davos Open Forum format, in which young people from the city are invited to interact with meeting participants on the key subjects of entrepreneurism and leadership.The meeting will also, for the first time, webcast press conferences and issue briefings live, enabling the public to submit questions on important issues facing Africa’s future.FDI leaderSpeaking at a media briefing in Johannesburg on Friday ahead of the summit, Minister in the Presidency Jeff Radebe said South Africa as a foreign direct investment destination was regarded as one of the best on the continent.“South Africa remains the most diverse economy on the continent – providing a supportive regulatory framework, a well-developed infrastructure network, a world- class financial hub and world-class services for business opportunities.”According to the United Nations Conference on Trade and Development, South Africa remained the top foreign direct investment destination in Africa during 2013, significantly increasing foreign direct investment inflows from $4.6-billion (R56.28- billion) in 2012 to $8.1-billion in 2013, mostly in green field’s investments.Radebe said South Africa continued to make strides in improving the ease of doing business.“South Africa, if compared to other Brics [Brazil, Russia, India, China and South Africa] nations, comes first in the five of the 10 criteria the World Bank uses to assess ease of doing business – starting a business, dealing with construction permits, getting credit, protecting investors and paying taxes,” he said.Convened for regional and global leaders from business, government and civil society, the forum will take stock of progress made over the last 25 years, share insights on the present landscape and identify innovative approaches to accelerate inclusive growth while bring about sustainable development in the future.SAinfo reporterlast_img read more

With Solskjaer overseeing the club’s worst start in 30 years, Allardyce has used the side from 45 years ago as a warning to the current crop that they are not too good to be relegated. He told talkSPORT: “It isn’t beyond the realms of possibility that they could catastrophically fall into more problems if confidence goes and injuries stay like they are.”Players tend not to get as fit as quick as they would do when things are going well, that’s an absolute fact.

Quebec Premier Francois Legault to address secularism bill in video message

first_imgMONTREAL — Quebec Premier Francois Legault will address his government’s controversial secularism bill tonight in a speech delivered via video.Legault’s office says the message will be broadcast on the premier’s official website and Facebook page at 5:30 p.m.The legislation tabled last week would prohibit public servants in positions of authority — including teachers, police officers, Crown prosecutors and prison guards — from wearing religious symbols.The Coalition Avenir Quebec’s legislation also invoked the notwithstanding clause, declaring the provisions of the bill would apply despite certain provisions of the Canadian Charter of Rights and Freedoms.The government has said the bill respects the wishes of most Quebecers, but critics have denounced it as discriminatory towards women as well as religious minorities such as Muslims, Jews and Sikhs.They say Muslim women wearing a hijab will bear the brunt of the law’s impact, and could face increasing stigmatization and violence in their everyday lives.The Canadian Presslast_img read more
