    Uncertainty principles connected with the Mobius inversion formula

    No full text
    We say that two arithmetic functions ff and gg form a \emph{M\"{o}bius pair} if f(n)=dng(d)f(n) = \sum_{d \mid n} g(d) for all natural numbers nn. In that case, gg can be expressed in terms of ff by the familiar M\"{o}bius inversion formula of elementary number theory. In a previous paper, the first-named author showed that if the members ff and gg of a M\"{o}bius pair are both finitely supported, then both functions vanish identically. Here we prove two significantly stronger versions of this uncertainty principle. A corollary of our results is that in a nonzero M\"{o}bius pair, one cannot have both $\sum_{f(n) \neq 0}\frac{1}{n

    Summer of Shrew, Part 3: A Sly Conceit

    No full text
    In the third of a four-part series on Shakespeare\u27s The Taming of the Shrew, Daniel Pollack-Pelzner asks, what if Kate’s story isn’t the play’s only reality? Pollack-Pelzner explores how a drunken beggar and an earlier version of the script shift the brawling balances of the play and call into question who the real shrew is

    EU standing request on catch scenarios for zero TAC stocks 2023: pollack (<i>Pollachius pollachius</i>) in subareas 6–7 (Celtic Seas and the English Channel)

    No full text
    ICES has provided forecasts on the development of pollack (Pollachius pollachius) in subareas 6–7 (Celtic Seas and the English Channel). There are no catch scenarios that will rebuild the stock above Blim by 2025. ICES, therefore, advises zero catch in 2024.Pollack is caught in demersal mixed fisheries although there are some fisheries targeting pollack in certain areas. Due to the large geographic range of this stock, regional differences in fishing practices, and the diverse range of species that are caught together with this stock, it is not possible to produce mixed‑fisheries scenarios for 2024.For pollack in subareas 6–7:If catches are such that stock biomass is stable between 2024 and 2025, it would result in a catch of 1363 tonnes in 2024;If catches are such that stock biomass increases by +10% between 2024 and 2025, it would result in a catch of 1145 tonnes in 2024;If catches are such that stock biomass increases by +20% between 2024 and 2025, it would result in a catch of 925 tonnes in 2024;If catches are such that stock biomass increases by +30% between 2024 and 2025, it would result in a catch of 705 tonnes in 2024.Pollack in subareas 6–7 is subject to a multiannual management plan (MAP), but FMSY ranges are not available. Options are provided to increase the stock biomass.Since pollack are taken as bycatch in mixed fisheries, a specific monitoring TAC is not required for this stock.</p

    The only woman in the room: why science is still a boys' club

    No full text
    In 2005, when Lawrence Summers, then president of Harvard, asked why so few women, even today, achieve tenured positions in the hard sciences, Eileen Pollack set out to find the answer. A successful fiction writer, Pollack had grown up in the 1960s and ’70s dreaming of a career as a theoretical astrophysicist. Denied the chance to take advanced courses in science and math, she nonetheless made her way to Yale. There, despite finding herself far behind the men in her classes, she went on to graduate summa cum laude, with honors, as one of the university’s first two women to earn a bachelor of science degree in physics. And yet, isolated, lacking in confidence, starved for encouragement, she abandoned her ambition to become a physicist. Years later, spurred by the suggestion that innate differences in scientific and mathematical aptitude might account for the dearth of tenured female faculty at Summer’s institution, Pollack thought back on her own experiences and wondered what, if anything, had changed in the intervening decades. Based on six years interviewing her former teachers and classmates, as well as dozens of other women who had dropped out before completing their degrees in science or found their careers less rewarding than they had hoped, The Only Woman in the Room is a bracingly honest, no-holds-barred examination of the social, interpersonal, and institutional barriers confronting women—and minorities—in the STEM fields. This frankly personal and informed book reflects on women’s experiences in a way that simple data can’t, documenting not only the more blatant bias of another era but all the subtle disincentives women in the sciences still face. The Only Woman in the Room shows us the struggles women in the sciences have been hesitant to admit, and provides hope for changing attitudes and behaviors in ways that could bring far more women into fields in which even today they remain seriously underrepresented

    A remark on sociable numbers of odd order

    No full text
    AbstractWrite s(n) for the sum of the proper divisors of the natural number n. We call n sociable if the sequence n, s(n), s(s(n)), … is purely periodic; the period is then called the order of sociability of n. The ancients initiated the study of order 1 sociables (perfect numbers) and order 2 sociables (amicable numbers), and investigations into higher-order sociable numbers began at the end of the 19th century. We show that if k is odd and fixed, then the number of sociable n⩽x of order k is bounded by x/(logx)1+o(1) as x→∞. This improves on the previously best-known bound of x/(loglogx)1/2+o(1), due to Kobayashi, Pollack, and Pomerance

    The Shifting Values of Port Cities: Towards “what if histories” and “design fiction”?

    No full text
    What if we had the chance to reboot and redesign our society? Who would have considered it possible that the current pandemic crisis offers exactly that opportunity? Within a matter of weeks, we have experienced a change in lifestyle that seemed impossible as a response to climate change a few months ago. The COVID-19 pandemic is hitting people and businesses hard. This is also true of ports and their surrounding cities. Attempts to protect people from a life-threatening disease have changed the functioning of such port cities around the world. In some, ships continue to deliver much-needed goods. But in others, they have become floating storage or laid up, upsetting the entire maritime system. Meanwhile, streets and public spaces are emptier than usual, with satellite images revealing significant drops in air pollution. While some people are working harder than ever—think of the medical professions—others have lost their jobs and their livelihood or even died.History, Form & Aesthetic
