Direct visualization of superselective colloid-surface binding mediated by multivalent interactions

Posted by dbos Delft

Kavli Affiliate: Liedewij Laan | First 5 Authors: Christine Linne, Daniele Visco, Stefano Angioletti-Uberti, Liedewij Laan, Daniela J. Kraft | Summary: Reliably distinguishing between cells based on minute differences in receptor density is crucial for cell-cell or virus-cell recognition, the initiation of signal transduction and selective targeting in directed drug delivery. Such sharp differentiation between […]

Two Bright M Dwarfs Hosting Ultra-Short-Period Super-Earths with Earth-like Compositions

Posted by klaurent MIT

Kavli Affiliate: Roland K. Vanderspek | First 5 Authors: Teruyuki Hirano, John H. Livingston, Akihiko Fukui, Norio Narita, Hiroki Harakawa | Summary: We present observations of two bright M dwarfs (TOI-1634 and TOI-1685: $J=9.5-9.6$) hosting ultra-short period (USP) planets, identified by the TESS mission. The two stars are similar in temperature, mass, and radius ($T_mathrm{eff},approx,3500$ […]

Gravitational wave backgrounds from coalescing black hole binaries at cosmic dawn: an upper bound

Posted by klaurent Peking

Kavli Affiliate: Kohei Inayoshi | First 5 Authors: Kohei Inayoshi, Kazumi Kashiyama, Eli Visbal, Zoltan Haiman, | Summary: The successive discoveries of binary merger events by Advanced LIGO-Virgo have been revealing the statistical properties of binary black hole (BBH) populations. A stochastic gravitational wave background (GWB) is a useful tool to probe the cosmological evolution […]

Understanding mechanisms of thermal expansion in PbTiO$_3$ thin-films from first principles: role of high-order phonon-strain anharmonicity

Posted by klaurent Cornell

Kavli Affiliate: Nicole A. Benedek | First 5 Authors: Ethan T. Ritz, Nicole A. Benedek, , , | Summary: The thermal properties of materials are critically important to various technologies and are increasingly the target of materials design efforts. However, it is only relatively recent advances in first-principles computational techniques that have enabled researchers to […]

The TESS Objects of Interest Catalog from the TESS Prime Mission

Posted by klaurent MIT

Kavli Affiliate: Christopher J. Burke | First 5 Authors: Natalia M. Guerrero, S. Seager, Chelsea X. Huang, Andrew Vanderburg, Aylin Garcia Soto | Summary: We present 2,241 exoplanet candidates identified with data from the Transiting Exoplanet Survey Satellite (TESS) during its two-year prime mission. We list these candidates in the TESS Objects of Interest (TOI) […]

Topological modular forms and the absence of a heterotic global anomaly

Posted by klaurent Tokyo

Kavli Affiliate: Yuji Tachikawa | First 5 Authors: Yuji Tachikawa, , , , | Summary: Spacetime theories obtained from perturbative string theory constructions are automatically free of perturbative anomalies, but it is not settled whether they are always free of global anomalies. Here we discuss a possible $mathbb{Z}_{24}$-valued pure gravitational anomaly of heterotic compactifications down […]

Inferring simple but precise quantitative models of human oocyte and early embryo development

Posted by dbos Harvard

Kavli Affiliate: Daniel Needleman | First 5 Authors: Brian D Leahy, Catherine Racowsky, Daniel Needleman, , | Summary: Macroscopic, phenomenological models have proven useful as concise framings of our understandings in fields from statistical physics to economics to biology. Constructing a phenomenological model for development would provide a framework for understanding the complicated, regulatory nature […]

Distinguishing Tidal Disruption Events from Impostors

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | First 5 Authors: Ann Zabludoff, Iair Arcavi, Stephanie La Massa, Hagai B. Perets, Benny Trakhtenbrot | Summary: Recent claimed detections of tidal disruption events (TDEs) in multi-wavelength data have opened potential new windows into the evolution and properties of otherwise dormant supermassive black holes (SMBHs) in the centres of galaxies.

Random-access quantum memory using chirped pulse phase encoding

Posted by klaurent Berkeley

Kavli Affiliate: Irfan Siddiqi | First 5 Authors: James O’Sullivan, Oscar W. Kennedy, Kamanasish Debnath, Joseph Alexander, Christoph W. Zollitsch | Summary: As in conventional computing, key attributes of quantum memories are high storage density and, crucially, random access, or the ability to read from or write to an arbitrarily chosen register. However, achieving such […]
