United States Tactical Doctrine, 1855 to 1861: The Mismeasure of Technology

This thesis illuminates the state of United States Army tactical doctrine at the beginning of the Civil War. In 1855, the weapons available to the United States Army left much to be desired in terms of firepower. Their limited range and lack of accuracy meant that they could not be relied upon to render the final decision in battle. The tactical system of 1855, however, blended this firepower with the shock action effect of bayonets and sabres, permitting the capabilities of the weaponry to be maximized on the battlefield while at the same time minimizing the deficiencies. This harmony between weapons and tactics was not to be long lived. In June 1855, the United States Army adopted the rifled musket which greatly increased the firepower capability of the infantry. However, the effect that this new firepower would have on the conduct of battle was not understood. Military manuals and literature published between 1855 and 1861 failed to adequately prepare the officer corps of 1861 for the carnage this weapon would produce on the battlefields of 1861 to 1865

Wage Dynamics and Peer Referrals

We present a flexible model of wage dynamics where information about job openings is transmitted through social networks. The model is based on Calvó-Armengol & Jackson (2004, 2007) and extends their results outside the stationary distribution, and under observed and unobserved heterogeneity. We present an empirical application using the British Household Panel Survey by exploiting direct information about individual’s social networks. We find that the distribution of job offers is positively affected by the employment status of an individual’s friends, and that this relationship is stronger for women

Interfacial toughness evolution under thermal cycling by laser shock and mechanical testing of an EB-PVD coating system

One of the major challenges for coatings on superalloys is to keep adherence during aging, where damage is mostly driven by thermal cycling. On the other hand, the methodology of the evaluation of the interfacial toughness should be consistent with in service loading. Recently, the use of LAser Shock Adhesion Test (LASAT) has shown its capability for both ranking different coating solutions and evaluating the evolution of a given coating as a function of aging [1-2]. The intent of this paper is to demonstrate the ability of LASAT to reproduce damage mechanisms observed under quasi-static in plane mechanical testing and to propose a general methodology to assess interfacial toughness evolution based on LASAT measurements. The material chosen in this study is a partially Y2O3 stabilized EB-PVD zirconia layer coating deposited by Electron Beam – Physical Vapor Deposition (EB-PVD) onto a first generation Ni base superalloy. Aging has been performed using thermal cycling under laboratory air. Degradation of the coating system due to ageing is quantitatively assessed by LASAT and accompanied by different microstructural analysis methods. For LASAT, if laser flux is below a threshold, no delamination occurs. When increasing laser flux above this threshold, a systematic sequence is observed: i) delamination without buckling of the ceramic layer, ii) delamination and buckling, iii) partial cracking of the ceramic layer, and iv) spallation [1-2]. These different states are also achieved in compressive quasi-static testing and assessed by means of local strain measurement using digital image correlation technique [3]. Aging is evaluated through the evolution of both the delamination and the buckling behavior induced by the LASAT method or critical strain at ceramic spallation under compressive static load.

Enhancing scientific dissemination in neuroscience via preprint peer-review: "Peer Community In Circuit Neuroscience"

The dissemination of scientific results and new technologies in biomedical science is rapidly evolving from an exclusive and fee-oriented publishing system towards more open, free and independent strategies for sharing knowledge. In this context, preprint servers such as bioRxiv answer a very real scientific need by enabling the rapid, free and easy dissemination of findings, regardless of whether these are novel, replicated, or even showcasing negative results. Currently, thousands of manuscripts are being shared via bioRxiv each month, and neuroscience is the largest and fastest growing subject category. However, commenting on bioRxiv is declining and no structured scientific validation such as peer-review is currently available. The Peer Community In (PCI) platform addresses this unmet need by facilitating the rigorous evaluation and validation of preprints, and PCI Circuit Neuroscience (PCI C Neuro) aims to develop and extend this tool for the neuroscience community. Here we discuss PCI C Neuro's mission, how it works, and why it is an essential initiative in this new era of open science

Transcriptional Regulation of the Intestinal Cancer Stem Cell Phenotype

Colorectal cancer (CRC) is one of the most frequent cancers worldwide. Current treatments include surgery and chemotherapy, but disease recurrence occurs frequently. The continuous renewal of intestinal epithelium relies on the presence of intestinal stem cells that are also at the origin of CRC and contribute to therapy resistance and metastatic dissemination. Several nuclear signaling pathways and transcription factors regulate both intestinal cell homeostasis and tumorigenesis. However, the transcriptional events that govern the emergence of aggressive therapy-resistant cancer stem cells are still poorly defined. This review summarizes the relevance of transcription factors in intestinal stem cell biology and their involvement in colon cancer development and drug resistance

Crack morphology in a columnar thermal barrier coating system

For high temperature application, EB-PVD ceramic layers are commonly used as thermal barrier coating. During thermal transients, the thermal expansion mismatch between coating and substrate drives failure of the TBC mainly by interfacial cracking. Laser Shock Adhesion Test (LASAT) provides stresses at the ceramic/metal interface enabling controlled interfacial cracking [1-2]. For achieving a clear understanding of the influence of local morphology on interfacial toughness, this study aims at characterizing the 3D morphology of a crack at the interface between metal and an EB-PVD TBC having a columnar structure.

Sublogarithmic uniform Boolean proof nets

Using a proofs-as-programs correspondence, Terui was able to compare two models of parallel computation: Boolean circuits and proof nets for multiplicative linear logic. Mogbil et. al. gave a logspace translation allowing us to compare their computational power as uniform complexity classes. This paper presents a novel translation in AC0 and focuses on a simpler restricted notion of uniform Boolean proof nets. We can then encode constant-depth circuits and compare complexity classes below logspace, which were out of reach with the previous translations.Comment: In Proceedings DICE 2011, arXiv:1201.034
