Nanoscale Protonation Limits and Charge Density in Polymer Films Govern the Activity of Immobilized LacZ under Acid Stress

Posted by dbos UCSF

Kavli Affiliate: Yifan Cheng | Authors: Huida Duan, Junxing Chen, Felicia Fianu, Wei Sun and Yifan Cheng | Summary: Under acidic conditions, polycationic polymer coatings function as protective immobilization supports through protonation-mediated local pH buffering. However, it remains unclear how polymer support design parameters, such as film thickness and charge density, govern that vital protonation […]

Testing the Association of Supermassive Black Hole Infrared Flares and High-energy Neutrinos

Posted by klaurent MIT

Kavli Affiliate: Erin Kara | Summary:The physical origin of the observed cosmic neutrinos remains an open question and the subject of active research. While matter accretion onto supermassive black holes is long thought to accelerate particles to high energies, it has recently been suggested that tidal disruption events, and accretion flares in general, with prominent […]

Anisotropic Kitaev Spin Glass in Li$_2$Ru$_x$Ir$_1-x$O$_3$

Posted by klaurent Berkeley

Kavli Affiliate: James Analytis| Summary:Kitaev iridates have emerged as an important class of spin-orbit-entangled quantum materials in which bond-directional exchange interactions generate strong magnetic frustration and unconventional correlated states. Rather than realizing simple ordered magnets, members of the alpha,beta,gamma-Li2IrO3 family exhibit fragile and highly anisotropic magnetic behavior, including incommensurate counter-rotating order, strong field sensitivity, and […]

Anisotropic Kitaev Spin Glass in Li$_2$Ru$_x$Ir$_1-x$O$_3$

Posted by klaurent Berkeley

Kavli Affiliate: James Analytis| Summary:Kitaev iridates have been proposed as candidates for realizing an elusive quantum spin liquid (QSL) state, in which strong spin-orbit coupling and bond-directional exchange generate a highly frustrated and entangled ground state. However, all physical systems proposed to host this ground state, including Li$_2$IrO$_3$, Na$_2$IrO$_3$, and RuCl$_3$, develop magnetic order at […]

Insights into the Physical Nature of Polar Ring Galaxies from H I Observations

Posted by klaurent Peking

Kavli Affiliate: Luis Ho | Summary:Polar ring galaxies (PRGs) host an outer ring of gas and stars oriented nearly perpendicular to the main stellar body. They represent extreme examples of misaligned systems and provide valuable insight into galaxy interactions, gas accretion, and peculiar gas dynamics. We compile a complete sample of kinematically confirmed PRGs and […]

Highest weight categories via pairs of dual exceptional sequences

Posted by klaurent Tokyo

Kavli Affiliate: Alexey Bondal | Summary:In this paper we present criteria in terms of dual pairs of exceptional sequences for an abelian category to be highest weight. The criteria are applied in three situations of geometric origin. We give new proofs for the facts that the category of perverse sheaves of middle perversity on complex-analytic […]

Knowledge Vector Weakening: Efficient Training-free Unlearning for Large Vision-Language Models

Posted by klaurent Stanford

Kavli Affiliate: Hsiao-Mei (Sherry) Cho| First 5 Authors: [#item_custom_name[1, [#item_custom_name[2, [#item_custom_name[3, [#item_custom_name[4, [#item_custom_name[5| Summary:Large Vision-Language Models (LVLMs) are widely adopted for their strong multimodal capabilities, yet they raise serious concerns such as privacy leakage and harmful content generation. Machine unlearning has emerged as a promising solution for removing the influence of specific data from trained […]

Evaluating Classifications of Extremely Metal-poor Candidates Selected from Gaia XP Spectra

Posted by klaurent Chicago

Kavli Affiliate: Alexander Ji | Summary:Extremely metal-poor stars are intrinsically rare, but emerging methods exist to accurately classify them from all-sky Gaia XP low-resolution spectra. To assess their overall accuracy for targeting metal-poor stars, we present a high-resolution spectroscopic followup of 75 very metal-poor candidates selected from the catalog by R. Andrae, V. Chandra, and […]
