Hilbert functions and symbolic powers.
Michigan Mathematical Journal, 1987 Let p be a prime ideal of the regular local ring R, and let \(p^{(n)}=p^ nR_ p\cap R\) be the n-th symbolic power of p. \textit{R. Cowsik} [in Algebra and its Applications, Int. Symp., New Delhi 1981, Lect. Notes Pure Appl. Math. 91, 13-14 (1984; Zbl 0562.13002)] asks whether the ring \(\oplus p^{(n)}\) is Noetherian; this question motivates much of ...

On the ordinary and symbolic powers of fiber products
We completely determine the depth and regularity of symbolic powers of the fiber product of two homogeneous ideals in disjoint sets of variables, given knowledge of the symbolic powers of each factor.

Self‐Cooling Molecular Spin Qudits
Advanced Materials, EarlyView.A material made of [GdEr] molecular dimers can encode a qudit and perform as a magnetic refrigerant. Microwave resonant pulses coherently manipulate its 16 spin states, while direct demagnetization measurements cool the material and a device down to temperatures below 1 K.

Advanced Materials, EarlyView.In this work, low bandgap (≈1.55 eV) semitransparent perovskite solar cells (ST‐PSCs) having thin (thickness < ≈100 nm) perovskite layers and transparent conductive oxide‐based rear electrodes are fabricated using vacuum‐deposition methods. Two different ST‐PSCs demonstrated a high light utilization efficiency value of 4.2 (PCE: 9.26% and AVT: 45.3 ...

Outline of an Anthropology of Muiscas from a southern perspective: parallels and transits
Universitas Humanística, 2013 This article aims to explore reflectively and critically the various ways in which symbolic powers operate on the anthropology of the Muisca Culture from the concerns raised, considering a southern perspective.

The Symbolic Body and the Rhetoric of Power
Social Analysis, 2010 In this article I will discuss the human body, both physical and social, as an instrument of political and aesthetic power and will analyze the processes of its social construction, starting with the notion of Corpus Mysticum Christi as the metaphoric organizational structure of consensus to power.

Advanced Materials, EarlyView.A high‐capacity polyimide‐linked porous organic polymer (HAT‐PTO) incorporating numerous redox‐active centers is synthesized via a hydrothermal reaction, delivering a high theoretical capacity of 484 mAh g−1. In situ hybridization with carboxyl‐functionalized multiwalled carbon nanotubes enhances conductivity and stability, achieving 397 mAh g−1 at C ...

Role of the Recombination Zone in Organic Light‐Emitting Devices
Advanced Materials, EarlyView.This review summarizes the critical role of the recombination zone in organic light‐emitting diodes (OLEDs). We highlight that broadening the recombination zone in OLEDs based on emissive layers with balanced charge transport and high photoluminescence quantum yields provides a promising route toward achieving both long operational lifetime and high ...

On Noetherian Rees algebras and symbolic powers
, 2008 My research explores the relationship of Noetherian Rees algebras and symbolic powers. Cowsik proposed a question: if R is a regular local ring and [special characters omitted] ⊂ R is a prime ideal, then is ⊕ n≥0[special characters omitted] Noetherian ...
