Ten current and former Samsung semiconductor engineers say many are leaving for SK Hynix and other rivals due to long hours, heavy workloads, and lower bonuses (Michelle Kim/Rest of World)

Samsung is desperate to compete on chips. Workers say it comes at a cost.
Scarred by long hours, low pay, and a hostile work culture, many chip workers are leaving for competitors, including American companies.

#EroticMusings Week 3 (June 15-21), Studio: Is your work in erotica integrated with your day-to-day life and work, or somewhat separate?
It's fully integrated, but I also have it easy. I work from home, so no strangers snooping. And I mostly write (and occasionally draw). When you enter the room, you see my set-up from the front or side, nothing to see there.

Standard posets and integral weight bases for symmetric powers of minuscule representations
This paper extends our earlier work where we constructed ``minuscule'' representations of Kac--Moody algebras from colored posets in a way that maintains key properties of the well-known minuscule representations of simple Lie algebras. In this paper we work only with finite posets. We define standard posets here as ones that can be used to construct weight bases of $m^\text{th}$ symmetric powers ($m \ge 1$) of these minuscule Kac--Moody representations over the integers in a certain fashion. O…

Cut Tracing with E-Graphs for Boolean FHE Circuit Synthesis
Fully Homomorphic Encryption (FHE) is a promising privacy-preserving technology enabling secure computation over encrypted data. A major limitation of current FHE schemes is their high runtime overhead. As a result, automatic optimization of circuits describing FHE computation has garnered significant attention in the logic synthesis community. Existing works primarily target the multiplicative depth (MD) and multiplicative complexity (MC) of FHE circuits, corresponding to the total number of m…

On quadratic persistence and Pythagoras numbers of totally real projective varieties
In this paper, we study the relationship between quadratic persistence and the Pythagoras number of totally real projective varieties. Building upon the foundational work of Blekherman et al. in arXiv:1902.02754, we extend their characterizations of arithmetically Cohen-Macaulay varieties with next-to-maximal quadratic persistence to arbitrary case. Our main result classifies totally real non-aCM varieties of codimension $c$ and degree $d$ that exhibit next-to-maximal quadratic persistence in t…

Gravitational wave propagation in hybrid metric-Palatini gravity
In this work we analyze the propagation properties of gravitational waves in the hybrid metric-Palatini gravity theory. We introduce the scalar-tensor representation of the theory to make explicit the scalar degrees of freedom of the theory and obtain their equations of motion in a form decoupled from the metric tensor. Then, we introduce linear perturbations for the metric tensor and for the two scalar fields and obtain the propagation equations for these three quantities. We analyzed the theo…

Few Single-Qubit Measurements Suffice to Certify Any Quantum State
A fundamental task in quantum information science is \emph{state certification}: testing whether a lab-prepared $n$-qubit state is close to a given hypothesis state. In this work, we show that \emph{every} pure hypothesis state can be certified using only $O(n^2)$ single-qubit measurements applied to $O(n)$ copies of the lab state. Prior to our work, it was not known whether even sub-exponentially many single-qubit measurements could suffice to certify arbitrary states. This resolves the main o…

Hydrodynamic theory of wetting by active particles
The accumulation of self-propelled particles on repulsive barriers is a widely observed feature in active matter. Despite being implicated in a broad range of biological processes, from biofilm formation to cytoskeletal movement, wetting of surfaces by active particles remains poorly understood. In this work, we study this active wetting by considering a model comprising an active lattice gas, interacting with a permeable barrier under periodic boundary conditions, for which an exact hydrodynam…

Volumetric Functional Maps
The computation of volumetric correspondences between 3D shapes has great potential for medical and industrial applications. In this work, we pave the way for spectral volume mapping, extending for the first time the functional maps framework from the surface setting to the volumetric domain. We show that the eigenfunctions of the volumetric Laplace operator define a functional space that is suitable for high-quality signal transfer. We also experiment with various techniques that edit this fun…
