Advanced Photonics Research, EarlyView.Electron acceleration using multipetawatt femtosecond lasers and subcritical density plasmas achieves a maximum charge of 245 nC, with an injection rate of up to 100 nC per picosecond. The charge variation with plasma density, initially increasing and then decreasing, arises from the competition between the injection of multiple plasma waves and laser ...

Difluoro Carbenes: From Genuine Gold Complexes to Unprecedented Metallacyclic Reactivity
Angewandte Chemie, EarlyView.Thanks to chelating ligands and enhanced backdonation, genuine gold(I) difluorocarbenes persistent for hours at −30 °C or even 0 °C have been obtained. In addition to classical Fisher‐type electrophilic behavior, these complexes display unprecedented reactivity toward alkenes and 1,3‐dienes.

Advanced Synthesis &Catalysis, EarlyView.In the presence of a Pd0 catalyst, large π‐extended arynes trimerize in an unusual manner to forge extremely compact and strained chiral benzenoids. This new trimerization reaction involves a 1,7‐Pd isomerization, a rare and poorly understood process that is elucidated.

Beyond Relativism? Re-engaging Wittgenstein [PDF]
, 2002 Relativism is the view that there are as many worlds as there are ways of thinking and expressing the worlds that are expressed. That is to say, things are related to the ways in which we express them. Thus philosophers assert that the way we express our

Relativism and our warrant for scientific theories [PDF]
, 2004 We depend upon the community for justified belief in scientific theory. This dependence can suggest that our individual belief in scientific theory is justified because the community believes it to be justified.

Disagreement, Cognitive Command, and the Indexicality of Moral Truth
Studies in Logic, Grammar and Rhetoric, 2015 Moral Relativism can be considered an attractive alternative to realism because relativists can make good sense of cultural and societal disagreements by seeing them as faultless.

ACSS2/AATF Drives Soluble FasL‐Mediated CD8+ T Cell Apoptosis in Pancreatic Neuroendocrine Tumors
Advanced Science, EarlyView.This study unveils that ACSS2‐driven acetate metabolism fuels histone pan‐acetylation in pancreatic neuroendocrine tumors (PNETs), remodeling the epigenetic landscape. The ACSS2/AATF axis transcriptionally activates soluble FasL (sFasL), which engages Fas receptors on infiltrating CD8+ T cells to trigger caspase‐8/3‐mediated apoptosis.

Transverse‐Electric Cherenkov Radiation for TeV‐Scale Particle Detection
Advanced Science, EarlyView.Finite refractive indices of naturally existing materials place a fundamental ceiling on the momentum of detectable particles in traditional Cherenkov detectors. This work demonstrates transverse‐electric graphene plasmon Cherenkov radiation, breaking the momentum barrier for particle detection beyond the TeV scale with exceptional robustness and ...

, 2016 In this essay we provide (1) an argument for why ethics should be naturalized, (2) an analysis of why it is not yet naturalized, (3) a defense of ethical naturalism against two fallacies—Hume’s and Moore’s—that ethical naturalism allegedly commits, and ...

"Putnamizacja absolutnie wszystkiego" i jej epistemologiczne reperkusje („Putnamisation of Absolutely Everything” and its Epistemological Repercussions) [PDF]
Analiza i Egzystencja, 2009 In the article inspired by Putnam’s thesis of „skolemisation of absolutely everything” (which is so called theory-modelling argument about semantic anti-realism) I try to describe Hilary Putnam’s style of philosophy, especially his argumentation in ...
