Two sets of ribosome structures have recently led to two different interpretations of what limits the accuracy of codon translation by transfer RNAs. In this review, inspired by this intermezzo at the Ribosome Club, we briefly discuss accuracy amplification by energy driven proofreading and its implementation in genetic code translation. We further discuss general ways by which the monitoring base

The properties of the bootstrap test for restrictions are studied in two versions: 1) bootstrapping under the null hypothesis, restricted, and 2) bootstrapping under the alternative hypothesis, unrestricted. This article demonstrates the equivalence of these two methods, and illustrates the small sample properties of the Wald test for testing Granger-Causality in a stable stationary VAR system by
Purpose: This study’s purpose is to study the long term effects of M&A and to examine whether stock price is the only determinant of post-merger performance or if operating performance can be used as an additional determinant. How underlying variables impact these measures are also part of this study´s purpose. Methodology: A quantitative approach is used where two event studies are conducte
Values, worldviews, and self-construal are strong correlates of pro-environmental behavior. In this brief empirical note, we argue that these constructs overlap conceptually and share underlying dimensions. Using an international sample of 11,964 individuals, we demonstrate that values, worldviews, and self-construal can be reduced to two dimensions, self-focus and other-focus, capturing 67 % of v
This article focuses on how academic and industrial leaders view central aspects of the initiation, collaboration process, and the outcomes in government-funded R&D projects. In much previous work on university-industry collaborations (UICs), universities or researchers and/or firms have been studied without any direct reference to the other party, thus neglecting the fact that the motivations
Evaluating the trade interdependence among countries is the key to understanding critical metal minerals security. By constructing a novel interdependence network, this paper reveals a more comprehensive world hierarchy and risk system of critical metals, and focuses on the interdependencies between China and the US-led MSP countries before and after the Sino-US trade disputes. The results indicat
Increased use of powerful PCR technology for the routine detection of pathogens has focused attention on the need for international validation and preparation of official non-commercial guidelines. Bacteria of epidemiological importance should be the prime focus, although a "validation infrastructure" once established could easily be adapted for PCR-based detection of viruses and parasites. The ai
Soft tissue sarcoma (STS) diagnostics and prognostics are challenging, particularly in highly malignant and pleomorphic subtypes such as undifferentiated pleomorphic sarcoma (UPS) and leiomyosarcoma (LMS). We applied 32K BAC arrays and gene expression profiling to 18 extremity soft tissue LMS and 31 extremity soft tissue UPS with the aim of identifying molecular subtype signatures and genomic prog
Four organizations at Stockholm-Arlanda airport are going through various organizational changes. They are preparing for present and future demands through structural changes, implementation of new technology, training, and other efficiency and capacity improving measures. The change processes will be followed during two years of which this paper presents the baseline measurement. The key factors
While foreign direct investments (FDI) are promoted as a vehicle for economic development their environmental consequences are less estab-lished. This study tests the hypotheses that 1) FDI led to environmental deg-radation in form of increased greenhouse gas emissions during Sub-Saharan Africa´s recent growth spurt but that 2) this impact was felt to a lesser extent in countries with a higher qua
