The America We Elected

On January 21st, hundreds of thousands of Americans traveled to Washington D.C. for President Obama's second Inauguration. I was among them to celebrate the event. Here are some of the people I met. These photos follow a set I took at the first Inauguration in 2009 as well as photos I took on the election night in November; I plan to continue attending every Inauguration in the future in order to document the type of people who gather for this event. I call the series "The America We Elected" because I am interested in focusing on the faces of the people in the crowd rather than the main spectacle shown in the media; it is interesting to think about how the faces would be different given a different outcome in the election. For instance, we are looking at radiantly happy people and strangers bonding together with a shared sense of hope, but we can imagine alternate situations where the people I would have encountered might have been angry protestors, or just entirely different demographics of the population. The main thrust of the project is to capture reality as it is and present this little seen aspect to a larger audience. The photos are unmanipulated, spontaneous, and captured on film by a Rolleiflex camera.

African American Women Leading in Tech

“Close your eyes and name three people who have impacted the tech industry.”

In all likelihood, that list might be overwhelmingly white and male.

And you are not alone. Numerous lists online yielded the same results. In recent years, many articles have chronicled the dearth of diversity in tech. Studies have shown the ways in which venture capital firms have systematically underestimated and undervalued innovation coming particularly from women of color. In 2016 only 88 tech startups were led by African American women, in 2018 this number had climbed to a little over 200. Between 2009 and 2017, African American women raised $289MM in venture/angel funding. For perspective, this only represents .0006% of the $424.7B in total tech venture funding raised in that same time frame. In 2018, only 34 African American women had ever raised more than a million in venture funding.

When it comes to innovation, it is not unusual for financial value to be the biggest predictor of what is considered innovative. In fact, a now largely controversial list posted by Forbes of America’s most innovative leaders in the fall of 2019 featured 99 men and one woman. Ironically, what was considered innovative was, in fact, very traditional in its presentation. The criteria used for the list was “media reputation for innovation,” social connections, a track record for value creation, and investor expectations for value creation.

The majority of African American women-led startups raise $42,000 from largely informal networks. Criteria weighted on the side of ‘track record for value creation’ and ‘investor expectations for value creation’ devalues the immense contributions of African American women leading the charge on thoughtful and necessary tech. Had Forbes used criteria for innovation that recognized emergent leadership, novel problem-solving, or original thinking outside the circles of already well-known and well-established entrepreneurs we might have learned something new. Instead, we're basically reminded that "it takes money to make money."

Meanwhile, African American women are the fastest-growing demographic of entrepreneurs in the United States. Their contributions to tech, amongst other fields, are cementing the importance of African American women in the innovation space. And they are doing this within and outside traditional tech frameworks. By becoming familiar with these entrepreneurs and their work, we can elevate their reputation and broaden our collective recognition of innovative leaders.

In honor of black history month, we have compiled a list of African American women founders leading the way in tech innovation from Alabama to the Bay Area. From rethinking energy to debt forgiveness platforms these women are crossing boundaries in every field.

African American Women Leading in Tech

“Close your eyes and name three people who have impacted the tech industry.”

In all likelihood, that list might be overwhelmingly white and male.

And you are not alone. Numerous lists online yielded the same results. In recent years, many articles have chronicled the dearth of diversity in tech. Studies have shown the ways in which venture capital firms have systematically underestimated and undervalued innovation coming particularly from women of color. In 2016 only 88 tech startups were led by African American women, in 2018 this number had climbed to a little over 200. Between 2009 and 2017, African American women raised $289MM in venture/angel funding. For perspective, this only represents .0006% of the $424.7B in total tech venture funding raised in that same time frame. In 2018, only 34 African American women had ever raised more than a million in venture funding.

When it comes to innovation, it is not unusual for financial value to be the biggest predictor of what is considered innovative. In fact, a now largely controversial list posted by Forbes of America’s most innovative leaders in the fall of 2019 featured 99 men and one woman. Ironically, what was considered innovative was, in fact, very traditional in its presentation. The criteria used for the list was “media reputation for innovation,” social connections, a track record for value creation, and investor expectations for value creation.

The majority of African American women-led startups raise $42,000 from largely informal networks. Criteria weighted on the side of ‘track record for value creation’ and ‘investor expectations for value creation’ devalues the immense contributions of African American women leading the charge on thoughtful and necessary tech. Had Forbes used criteria for innovation that recognized emergent leadership, novel problem-solving, or original thinking outside the circles of already well-known and well-established entrepreneurs we might have learned something new. Instead, we're basically reminded that "it takes money to make money."

Meanwhile, African American women are the fastest-growing demographic of entrepreneurs in the United States. Their contributions to tech, amongst other fields, are cementing the importance of African American women in the innovation space. And they are doing this within and outside traditional tech frameworks. By becoming familiar with these entrepreneurs and their work, we can elevate their reputation and broaden our collective recognition of innovative leaders.

In honor of black history month, we have compiled a list of African American women founders leading the way in tech innovation from Alabama to the Bay Area. From rethinking energy to debt forgiveness platforms these women are crossing boundaries in every field.

EMSx: A Numerical Benchmark for Energy Management Systems. (arXiv:2001.00450v2 [math.OC] UPDATED)

Inserting renewable energy in the electric grid in a decentralized manneris a key challenge of the energy transition. However, at local scale, both production and demand display erratic behavior, which makes it delicate to match them. It is the goal of Energy Management Systems (EMS) to achieve such balance at least cost. We present EMSx, a numerical benchmark for testing control algorithms for the management of electric microgrids equipped with a photovoltaic unit and an energy storage system. EMSx is made of three key components: the EMSx dataset, provided by Schneider Electric, contains a diverse pool of realistic microgrids with a rich collection of historical observations and forecasts; the EMSx mathematical framework is an explicit description of the assessment of electric microgrid control techniques and algorithms; the EMSx software EMSx.jl is a package, implemented in the Julia language, which enables to easily implement a microgrid controller and to test it. All components of the benchmark are publicly available, so that other researchers willing to test controllers on EMSx may reproduce experiments easily. Eventually, we showcase the results of standard microgrid control methods, including Model Predictive Control, Open Loop Feedback Control and Stochastic Dynamic Programming.

Numerical study on the effect of geometric approximation error in the numerical solution of PDEs using a high-order curvilinear mesh. (arXiv:1908.09917v2 [math.NA] UPDATED)

When time-dependent partial differential equations (PDEs) are solved numerically in a domain with curved boundary or on a curved surface, mesh error and geometric approximation error caused by the inaccurate location of vertices and other interior grid points, respectively, could be the main source of the inaccuracy and instability of the numerical solutions of PDEs. The role of these geometric errors in deteriorating the stability and particularly the conservation properties are largely unknown, which seems to necessitate very fine meshes especially to remove geometric approximation error. This paper aims to investigate the effect of geometric approximation error by using a high-order mesh with negligible geometric approximation error, even for high order polynomial of order p. To achieve this goal, the high-order mesh generator from CAD geometry called NekMesh is adapted for surface mesh generation in comparison to traditional meshes with non-negligible geometric approximation error. Two types of numerical tests are considered. Firstly, the accuracy of differential operators is compared for various p on a curved element of the sphere. Secondly, by applying the method of moving frames, four different time-dependent PDEs on the sphere are numerically solved to investigate the impact of geometric approximation error on the accuracy and conservation properties of high-order numerical schemes for PDEs on the sphere.

Determinantal Point Processes in Randomized Numerical Linear Algebra. (arXiv:2005.03185v1 [cs.DS])

Randomized Numerical Linear Algebra (RandNLA) uses randomness to develop improved algorithms for matrix problems that arise in scientific computing, data science, machine learning, etc. Determinantal Point Processes (DPPs), a seemingly unrelated topic in pure and applied mathematics, is a class of stochastic point processes with probability distribution characterized by sub-determinants of a kernel matrix. Recent work has uncovered deep and fruitful connections between DPPs and RandNLA which lead to new guarantees and improved algorithms that are of interest to both areas. We provide an overview of this exciting new line of research, including brief introductions to RandNLA and DPPs, as well as applications of DPPs to classical linear algebra tasks such as least squares regression, low-rank approximation and the Nystr"om method. For example, random sampling with a DPP leads to new kinds of unbiased estimators for least squares, enabling more refined statistical and inferential understanding of these algorithms; a DPP is, in some sense, an optimal randomized algorithm for the Nystr"om method; and a RandNLA technique called leverage score sampling can be derived as the marginal distribution of a DPP. We also discuss recent algorithmic developments, illustrating that, while not quite as efficient as standard RandNLA techniques, DPP-based algorithms are only moderately more expensive.

Catalyst for living radical polymerization and polymerization method

A nonmetallic compound having an ionic bond with a halide ion is used as a catalyst for living radical polymerization. Even if a radical initiator is not used, a monomer can be subjected to a radical polymerization to obtain a polymer having narrow molecular weight distribution. The cost of the living radical polymerization can be remarkably reduced, and it is made possible to prevent adverse effects of using a radical initiator (such as side reactions). The present invention is significantly more environmentally friendly and economically excellent than conventional living radical polymerization methods, due to advantages such as low toxicity of the catalyst, low amount of the catalyst necessary, high solubility of the catalyst, mild reaction conditions, and no coloration/no odor, etc. The catalyst can be applied to various monomers and enables synthesis of high molecular weight polymers.

C6-hydrocarbons are removed from the stabilizer overhead vapor stream to form a HCl and H2-rich stream. An isomerization catalyst is activated using at least a portion of the HCl and H2-rich stream to form a chloride-promoted isomerization catalyst. A paraffin feed stream is contacted with the chloride-promoted isomerization catalyst in the presence of hydrogen for isomerization of the paraffins.
