Nonlinear Correction to the Euler Buckling Formula for\ud Compressible Cylinders [PDF]

open access: yes, 2010
Euler’s celebrated buckling formula gives the critical load N for the buckling of a slender cylindrical column with radius B and length L as\ud \ud N/(π 3B2)=(E/4)(B/L)2,\ud \ud where E is Young’s modulus.

Bausteine zu einer Oral History der Wissenschaftsgeschichte Auf der Suche: von der Biologie und der Philosophie zur Wissenschaftsgeschichte. Interview mit Soraya de Chadarevian

open access: yesBerichte zur Wissenschaftsgeschichte, Volume 48, Issue 3, Page 266-289, October 2025.
Wie kann man einen historischen Blick auf das eigene Fach werfen? Diese Frage ist nicht einfach zu beantworten – will man einerseits nicht in einer Nabelschau und Hagiographie enden, andererseits aber auch keinen umfassenden Entwurf einer zukünftigen Historiographie vorlegen.

Characterization of Transcription Termination‐Associated RNAs: New Insights into their Biogenesis, Tailing, and Expression in Primary Tumors

open access: yesInternational Journal of Genomics, Volume 2018, Issue 1, 2018., 2018
Next‐generation sequencing has uncovered novel classes of small RNAs (sRNAs) in eukaryotes, in addition to the well‐known miRNAs, siRNAs, and piRNAs. In particular, sRNA species arise from transcription start sites (TSSs) and the transcription termination sites (TTSs) of genes. However, a detailed characterization of these new classes of sRNAs is still

Use of community characteristics to predict hunting and game harvests in western Amazonian forests

open access: yesConservation Biology, Volume 39, Issue 4, August 2025.
Abstract Wild game harvesting in Amazonia provides rural residents with protein and cash income but can threaten wildlife populations and forest ecosystem functions. As yet, the socioeconomic and environmental drivers that shape hunter livelihoods remain poorly understood.

Hiwi Knockdown Inhibits the Growth of Lung Cancer in Nude Mice

open access: yesAsian Pacific Journal of Cancer Prevention, 2013
Hiwi, a human homologue of the Piwi family, plays an important role in stem cell self-renewal and is overexpressed in various human tumors. This study aimed to determine whether an RNA interference-based strategy to suppress Hiwi expression could inhibit tumor growth in a xenograft mouse model.

A war-prone tribe migrated out of Africa to populate the world. [PDF]

open access: yes, 2010
Of the tribal hunter gatherers still in existence today, some lead lives of great violence, whereas other groups live in societies with no warfare and very little murder^1,2,3,4,5^.

Characterization of the Small RNA Transcriptome of the Marine Coccolithophorid, Emiliania huxleyi [PDF]

open access: yes, 2016
Small RNAs (smRNAs) control a variety of cellular processes by silencing target genes at the transcriptional or post-transcription level. While extensively studied in plants, relatively little is known about smRNAs and their targets in marine ...

The potential value of cancer‐testis antigens in ovarian cancer: Prognostic markers and targets for immunotherapy

open access: yesImmunity, Inflammation and Disease, Volume 12, Issue 6, June 2024.
Cancer‐testis antigens (CTAs) exhibit carcinogenic potential and strong immunogenicity in ovarian cancer. This review outlines a comprehensive of overview the regulatory mechanism, immunogenicity, clinical expression significance, tumorigenesis, and application prospects of CTAs in ovarian cancer, all of which can provide novel insights in the ...

PiwiRNA-651 as marker of treatment response and survival in classical Hodgkin lymphoma. [PDF]

open access: yes, 2017
PiwiRNAs, small non-coding RNAs processed by Piwi proteins, are involved in maintaining genome stability in germline cells. Recently, piwiRNA expression has been identified in some tumors.
