The data shows the explosion in use of the drugs for weight loss.

It’s not the mistakes that matter. Apple has made them before. The Newton, MobileMe, the butterfly keyboard. What matters is the posture. A company once defined by joyful provocation—by thinking different—is now defined by its defensiveness. Its leadership acts not like inventors but like stewards of a status quo. They protect margins like relics. They fear dilution. They optimize at the expense of surprise.

Apple’s Diet of Worms
On a crisp April morning in 1521, the twenty-one-year-old Emperor Charles V entered the Bishop’s Palace in Worms. The weight of a continent rested on his adolescent shoulders, and he carried it with the stiff dignity of someone raised to believe history itself had chosen him. He wore black

Volume Entropy Rigidity for Random Groups at Low Densities
We study the rigidity of the volume entropy for weighted word metrics on hyperbolic groups, building on a recent convexity result due to Cantrell-Tanaka. Using ideas from small cancellation theory, we give conditions under which a hyperbolic group admits a unique normalized weight minimizing the entropy. Moreover, we show that these conditions are generic for random groups at small densities, and that the unique minimizer of such a generic group is arbitrarily close to the uniform weight.

1-D Schrödinger operator on a star graph with nondefinite weight function
On a star graph $G$ with $n = n_+ + n_-$ edges of unit length, we study the operator $-\frac{\mathrm{d}^2}{\mathrm{d} x^2}$ on $n_+$ and $\frac{\mathrm{d}^2}{\mathrm{d} x^2}$ on $n_-$ edges equipped with Dirichlet boundary conditions at the outer vertices and a Kirchhoff condition at the central vertex. We study the spectral properties of the corresponding indefinite Kirchhoff Laplacian on $G$ and we show that it is similar to a selfadjoint operator in the Hilbert space $L^2(G)$ and that its ei…

Highest-weight vectors and three-point functions in GKO coset decomposition
We revisit the classical Goddard-Kent-Olive coset construction. We find the formulas for the highest weight vectors in coset decomposition and calculate their norms. We also derive formulas for matrix elements of natural vertex operators between these vectors. This leads to relations on conformal blocks. Due to the AGT correspondence, these relations are equivalent to blowup relations on Nekrasov partition functions with the presence of the surface defect. These relations can be used to prove K…

Analysis of the Plancherel weight and factoriality of the group von Neumann algebras of non-unimodular totally disconnected groups
Let $G$ be a locally compact group, $L(G)$ be its group von Neumann algebra equipped with the Plancherel weight $φ_G$. In this paper, we consider the following two questions. (1) When is the restriction of $φ_G$ to the subalgebra generated by a closed subgroup $H$ semifinite? If so, is it equal (up to a constant) to $φ_H$? (2) When is $L(G)$ a factor? We give a complete answer to (1), and when $G$ is second countable, totally disconnected and admits a sufficiently large non-unimodular part, …

A Selberg-type zero-density result for twisted $\rm GL_2$ $L$-functions and its application
Let $f$ be a fixed holomorphic primitive cusp form of even weight $k$, level $r$ and trivial nebentypus $χ_r$. Let $q$ be an odd prime with $(q,r)=1$ and let $χ$ be a primitive Dirichlet character modulus $q$ with $χ\neqχ_r$. In this paper, we prove an unconditional Selberg-type zero-density estimate for the family of twisted $L$-functions $L(s, f \otimes χ)$ in the critical strip. As an application, we establish an asymptotic formula for the even moments of the argument function $S(t, f…

Generic weights for finite reductive groups
This paper is motivated by the study of Alperin's weight conjecture in the representation theory of finite groups. We generalize the notion of $e$-cuspidality in the $e$-Harish-Chandra theory of finite reductive groups, and define generic weights in non-defining characteristic. We show that the generic weights play an analogous role as the weights defined by Alperin in the investigation of the inductive Alperin weight condition for simple groups of Lie type at most good primes. We hope that our…

Phantom chain simulations for fracture of star polymer networks on the effect of arm molecular weight
This study investigated the fracture of star polymer networks made from prepolymers with various arm molecular weights in the range $2 \leq N_a \leq 0$, for node functionalities $3 \leq f \leq 8$ and conversion ratios $0.6\leqϕ_c\leq0.95$ by phantom chain simulations. The networks were created via end-linking reactions of star polymers dispersed in a simulation box with a fixed monomer density $ρ=8$. The resultant networks were alternatively subjected to energy minimization and uniaxial stret…

Simultaneous probes of pseudogap and disorder by hard x-ray photoemission applied for a candidate thermoelectric Al-Pd-Ru quasicrystal
The bulk electronic structure of Al-Pd-Ru quasicrystal (QC) have been investigated by hard X-ray photoemission spectroscopy (HAXPES). We have found an intrinsic pseudogap structure in which the spectral weight in the vicinity of the Fermi level (E_F) is remarkably suppressed at any photon energy. The valence-band HAXPES spectra and the asymmetry of the core-level peaks indicate a contribution of the Al sites to the electronic structure in the vicinity of E_F with less contributions from the Pd …

Doubling Inequality and Strong Unique Continuation for an Elliptic Transmission Problem
We investigate the Strong Unique Continuation Property (SUCP) for elliptic equations with piecewise Lipschitz coefficients exhibiting jump discontinuities across a regular interface. We prove SUCP at the interface using a doubling inequality derived from a Carleman estimate with a singular weight. This result is intended as a first step toward solving the inverse problem of estimating the size of an unknown, merely measurable, inclusion inside a conductor from boundary measurements.

Omnivorous? Vegan? Makes no difference to muscle building after weight training, study finds
A new study asked three questions about muscle protein synthesis in response to a nine-day diet and weight training regimen: First, does the source of protein—plant or animal-based—make any difference to muscle gain? Second, does it matter if total daily protein intake is evenly distributed throughout the day? And third, does a moderate but sufficient daily protein intake influence any of these variables? The answer to all three questions is "no," the researchers found.

We present a novel integral criterion for the Riemann Hypothesis based on a regulated, normalized surface integral involving a logarithmic weight and the reciprocal square of the Riemann zeta function. The construction distinguishes symmetric from asymmetric zero configurations and converges if and only if all nontrivial zeros lie on the critical line. Analytical arguments are supported by model computations and operator-theoretic reformulations. The resulting structure provides a new functiona…

Organizational Regularities in Recurrent Neural Networks
Previous work has shown that the dynamical regime of Recurrent Neural Networks (RNNs) - ranging from oscillatory to chaotic and fixpoint behavior - can be controlled by the global distribution of weights in connection matrices with statistically independent elements. However, it remains unclear how network dynamics respond to organizational regularities in the weight matrix, as often observed in biological neural networks. Here, we investigate three such regularities: (1) monopolar output weigh…

First, the definition of disjoint Ces$\grave{a}$ro-hypercyclic operators is provided, and disjoint Ces$\grave{a}$ro-Hypercyclicity Criterion is proposed. Later, two methods are used to prove that operators satisfying this criterion possess disjoint Ces$\grave{a}$ro-hypercyclicity. Finally, this paper further investigates weighted shift operators and provides detailed characterizations of the weight …

DECA: A Near-Core LLM Decompression Accelerator Supporting Out-of-Order Invocation
To alleviate the memory bandwidth bottleneck in Large Language Model (LLM) inference workloads, weight matrices are stored in memory in quantized and sparsified formats. Hence, before tiles of these matrices can be processed by in-core generalized matrix multiplication (GeMM) hardware engines, they need to be dequantized and de-sparsified. This is currently performed in software with vector operations. Unfortunately, this approach delivers only modest performance. Moreover, it is hard to unders…

Using the tableau model for crystals, we construct an explicit and self-contained bijection between their highest weight elements and Sundaram's branching model.

Weyl laws for exponentially small singular values of the $\overline{\partial}$ operator
We study the number of exponentially small singular values of the semiclassical $\overline{\partial}$ operator on exponentially weighted $L^2$ spaces on the two-dimensional torus. Accurate upper and lower bounds on the number of such singular values are established with the help of auxiliary notions of upper and lower bound weights. Assuming that the Laplacian of the exponential weight changes sign along a curve, we construct optimal such weights by solving a free boundary problem, which yields…

The Lagrangian multiplier method has proven highly effective in addressing the ill-conditioning of full waveform inversion (FWI). It enables the development of robust and computationally efficient algorithms capable of converging to accurate velocity models, even from poor initial estimates. Traditionally, these methods optimize an Augmented Lagrangian (AL) function, using a scalar penalty parameter to weight the quadratic penalty term for wave-equation constraint violations. This penalty balan…

Since any smooth solution can be embedded into a self-similar solution at the identity scale, it follows that under standard flow conditions, the initial solution will remain smooth for all time as long as the self-similar solution is selected to have certain isobaric weight.
