Smartphone-integrated RPA-CRISPR-Cas12a Detection System with Microneedle Sampling for Point-of-Care Diagnosis of Potato Late Blight in Early Stage
Potato late blight, caused by the oomycete pathogen Phytophthora infestans, is one of the most devastating diseases affecting potato crops in the history. Although conventional detection methods of plant diseases such as PCR and LAMP are highly sensitive and specific, they rely on bulky and expensive laboratory equipment and involve complex operations, making them impracticable for point-of care diagnosis in the field. Here in this study, we report a portable RPA-CRISPR based diagnosis system f…

Whenever two Americans meet, we find ourselves talking about "the situation," an eerie crossover from lands of war and dictatorship.
My thoughts on the big picture, and why I have more reason for concern and more hope in resisting than I expected.

Trump’s authoritarian turn is everyone’s problem
It’s May 2025, and it feels like every new conversation (in my circles? in the United States? far beyond that?) needs to start with an acknowledgement of the bleak bigger picture on the natio…

Sobolev inequality and its extremal functions for homogeneous Hörmander vector fields
Let $X=(X_1,X_{2},\ldots,X_m)$ be a system of homogeneous Hörmander vector fields defined on $\mathbb{R}^n$. In this paper, we establish connections between the volume growth rate set of subunit balls and the admissible conjugate Sobolev exponents set on arbitrary open subsets $Ω\subset \mathbb{R}^n$. By analyzing further properties of these sets, we derive Sobolev inequalities and provide explicit conditions for the optimality of the corresponding Sobolev exponents, particularly for bounded …

Analogous supercritical crossovers in black holes and water
We investigate the supercritical crossovers for black hole thermodynamics in the supercritical regime beyond the critical point, where small and large black holes are indistinguishable from the conventional viewpoint. We establish a refined supercritical phase diagram that comprehensively characterizes small, large, and indistinguishable black hole phases, whose boundaries are defined by two supercritical crossover lines. The universal scaling laws of the two crossover lines are fully verified …

Black hole/quantum machine learning correspondence
We explore a potential connection between the black hole information paradox and the double descent phenomenon in quantum machine learning. Information retrieval from Hawking radiation can be viewed through the lens of quantum linear regression over black hole microstates, with the Page time corresponding to the interpolation threshold, beyond which test error decreases despite overparameterization. Using the Marchenko-Pastur law, we derive the variance in test error for the quantum linear regr…

Bulk Excitations of Invertible Phases
Recent developments in the study of topological defects highlight the importance of understanding the multi-dimensional structure of bulk excitations inside a quantum system. When the bulk ground state is trivial, i.e. a product state, excitations on top of it are decoupled from each other and correspond to lower-dimensional phases and their defects within. In this paper, we expand the discussion to invertible phases and study the bulk excitations in, for example, SPT phases, Majorana chains, p…

Quasi-normal modes and echoes of generalized black hole bounces and their correspondence with shadows
We study the quasi-normal modes (QNMs) of a family of generalized black bounces interpolating between regular black holes and traversable wormhole solutions according to a single extra parameter $a$. Firstly, working with a generic spherically symmetric space-time with arbitrary radial function and an anisotropic fluid matter source, the general equations for the gravitational waves are obtained. Then, we focus on such particular space-time metric and use the time-domain method to find the evol…
