AMPA receptors (AMPARs) mediate the majority of fast excitatory transmission in the brain and critically contribute to synaptic plasticity and pathology. AMPAR trafficking and gating are tightly controlled by auxiliary transmembrane AMPAR regulatory proteins (TARPs). Here, using systematic domain swaps with the TARP-insensitive kainate receptor GluK2, we show that AMPAR interaction with the prototypical TARP stargazin/γ2 primarily involves...

There is an increasing demand for realizing a simple Si based universal memory device working at ambient temperatures. In principle, nonvolatile magnetic memory can operate at low power consumption and high frequencies. However, in order to compete with existing memory technology, size reduction and simplification of the used material systems are essential. In this work, the chiral‐induced spin selectivity effect is used along with 30–50 nm...

Cysteine catabolism presents cells with a double-edged sword. On the one hand, cysteine degradation provides cells with essential molecules such as taurine and sulfide. The formation of sulfide in cells is thought to regulate important and diverse physiological processes including blood circulation, synaptic activity and inflammation. On the other hand, the catabolism of cysteine by gut microbiota can release high levels of sulfide that may...

While presenting an initiative to potential backers, the entrepreneur can choose the extent to which she presents herself, versus presenting the idea. We investigate this decision and its effect on the success of the fundraising on a leading crowdfunding platform (Kickstarter). We employ a text mining quantification method validated by experiments and robustness tests. Our dataset was collected using custom software and includes over 20,000...

The cutoff phenomenon was recently confirmed for random walks on Ramanujan graphs by the first author and Peres. In this work, we obtain analogs in higher dimensions, for random walk operators on any Ramanujan complex associated with a simple group G over a local field F. We show that if T is any k-regular G-equivariant operator on the Bruhat-Tits building with a simple combinatorial property (collision-free), the associated random walk on...

We study how people reconcile conflicting moral intuitions by juxtaposing two versions of classic moral problems: the trolley problem and the footbridge problem. When viewed separately, most people favor action in the former and disapprove of action in the latter, despite identical consequences. The difference is often explained in terms of the intention principle—whether the consequences are intended or incidental. Our results suggest that...

We report the results of a parquet renormalization group (RG) study of competing instabilities in the full 2D four-pocket, three-orbital low-energy model for iron-based superconductors. We derive and analyze the RG flow of the couplings, which describes all symmetry-allowed interactions between low-energy fermions. Despite that the number of the couplings is large, we argue that there are only two stable fixed trajectories of the RG flow and...

The proliferation of regional economic organizations (REOs) is a prominent feature of the contemporary international environment. Many of these organizations aspire to promote regional peace and stability. Some strive to promote these goals only through economic cooperation, while others have expanded their mandate to include mechanisms that address security concerns more directly. A glance at the security components of such organizations...

We present the first parser for UCCA, a cross-linguistically applicable framework for semantic representation, which builds on extensive typological work and supports rapid annotation. UCCA poses a challenge for existing parsing techniques, as it exhibits reentrancy (resulting in DAG structures), discontinuous structures and non-terminal nodes corresponding to complex semantic units. To our knowledge, the conjunction of these formal...

Financial crime, often referred to as “white-collar” crime, is a severe issue all around the world. A recent FBI survey found that in the preceding twelve months, approximately one in every four United States citizens had fallen victim to financial crime in one form or another (fraud, money laundering, internal embezzlement, impersonation, forgery, blackmail, theft, etc.).

The extent of financial crime in financial services companies over the...

Private-key functional encryption enables fine-grained access to symmetrically-encrypted data. Although private-key functional encryption (supporting an unbounded number of keys and ciphertexts) seems significantly weaker than its public-key variant, its known realizations all rely on public-key functional encryption. At the same time, however, up until recently it was not known to imply any public-key primitive, demonstrating our poor...

The Atlantic and Pacific Oceans represent different biogeochemical regimes in which the abundant marine cyanobacterium Prochlorococcusthrives. We have shown that Prochlorococcus populations in the Atlantic are composed of hundreds of genomically, and likely ecologically, distinct coexisting subpopulations with distinct genomic backbones. Here we ask if differences in the ecology and selection pressures between the Atlantic and Pacific are...

From the 19th–20th-century beginnings of modern linguistics, scholars reported on various results of interactions between diverse language speakers; but it was only with Uriel Weinreich’s Languages in Contact (1953) that a solid theoretical basis for the systematic study of contact linguistics was elaborated. The present article studies lexical influences from South Slavic on Judezmo (Ladino/Judeo-Spanish) resulting from contact during the...

Database management systems operating over encrypted data are gaining signicant commercial interest. CryptDB is one such notable system supporting a variety SQL queries over encrypted data (Popa et al., SOSP '11). It is a practical system obtained by utilizing a number of encryption schemes, together with a new cryptographic primitive for supporting SQL's join operator. This new primitive, an adjustable join scheme, is an encoding scheme...

We discuss the basic physics of the flow of micron-scale droplets in 2D geometry. Our focus is on the use of droplet ensembles to look into fundamental questions of non-equilibrium systems, such as the emergence of dynamic patterns and irreversibility. We review recent research in these directions, which demonstrate that 2D microfluidics is uniquely set to study complex out-of-equilibrium phenomena thanks to the simplicity of the underlying...

Universities, often at the center of innovative clusters, are believed to be important drivers of local economic growth. This paper identifies the extent to which U.S. universities stimulate nearby economic activity using the interaction of a national shock to the spread of innovation from universities - the Bayh-Dole Act of 1980 - with pre-determined variation both within a university in academic strengths and across universities in federal...

A basic intuition is that arbitrage is easier when markets are most liquid. Surprisingly, we find that momentum profits are markedly larger in liquid market states. This finding is not explained by variation in liquidity risk, time-varying exposure to risk factors, or changes in macroeconomic condition, cross-sectional return dispersion, and investor sentiment. The predictive performance of aggregate market illiquidity for momentum profits...

Standing is a peculiar norm, allowing for deflecting that is rejecting offhand and without deliberation interventions such as directives. Directives are speech acts that aim to give directive-reasons, which are reason to do as the directive directs because of the directive. Standing norms, therefore, provide for deflecting directives regardless of validity (i.e., regardless of whether or not a directive succeeds in giving a directive-reason)...

We show that the group of almost automorphisms of a d‐regular tree does not admit lattices. As far as we know, this is the first such example among (compactly generated) simple locally compact groups.

The present chapter outlines the historical development of lexicography in Judezmo, the traditional language of the Sephardic Jews of the former Ottoman Empire and its successor states, and Ḥaketía, the language of the Sephardim of Spanish Morocco. After notes on the thematic limitations of the chapter and on present-day Judezmo orthography, introductory notes are provided on Judezmo and Ḥaketía. The developmental stages of Judezmo and...
