ABSTRACTA fabrication process for sub-100 nm Ge wires on Si substrates is reported for the first time. Wires with a cross section of 6 × 57 nm2 are demonstrated. The wire structures are analyzed by atomic force (AFM), scanning electron (SEM), and transmission electron microscopy (TEM). Sample preparation for TEM is performed using a novel technique using both pre and in situ deposition of multiple protection layers using a Focused Ion Beam (FIB) micromachining system.

In legged mobile robotics the most common approach is to design fully actuated legs with several degrees of freedom (DOF) in order to successfully navigate through rough terrains. However, simpler leg architectures with as few as one-DOF have been developed in the past to achieve the very same goal. The ability of these simpler legs to traverse uneven terrains is arguably limited with respect to multi-DOF designs, but in some applications the reduction of the DOF and hence, of the number of actuators, as well as the simplicity of the associated control could be a great advantage and the decisive argument. In this paper, the authors propose a novel one-DOF robotic leg that has been specially designed to achieve the greatest robustness possible with respect to the difficult terrains it has to traverse. In order to do that, a method to analyze and optimize any one-DOF robotic leg with respect to its ability to overcome obstacles is proposed here. This method is based on a simple and efficient novel technique to generate synthetic terrains combined with a simulation algorithm estimating the traversability of the particular one-DOF leg design under scrutiny. To illustrate the generality of the proposed method, it is used to design both an optimal leg with the architecture presented here for the first time and also, one with the most common one-DOF leg architecture found in the literature.

ABSTRACT Genetic studies of Campylobacter jejuni have been limited due to the lack of a transposon mutagenesis method. Here, we describe a novel technique for random transposon mutagenesis using amariner-based transposon into C. jejuni strain 480. Insertions were random, as demonstrated by Southern blot analysis and insertional junction sequencing. We have demonstrated, for the first time, random in vivo transposon mutagenesis of C. jejuni.

The silver–calcium system has been reinvestigated over the whole composition range by thermal analysis, X-ray diffraction, and metallography. A novel technique has been used to prepare and examine these reactive alloys. In the course of this project four intermetallic compounds have been observed for the first time; while two others, viz., Ag2Ca and AgCa, which were reported before by others, have been confirmed. Three of the new compounds are: Ag8Ca3, Ag3Ca5, and AgCa3, while the fourth was not isolated or examined in detail. Two other compounds which were described in earlier work as Ag4Ca and Ag3Ca, have been found to be Ag9Ca2 and Ag7Ca2, respectively. Major modifications have been made in the liquidus curve and possible reactions in the solid state are indicated.

This paper both expands and reconceptualizes our knowledge about the early (January 1947 to January 1948) and formative responses of American archaeologists and anthropologists to word and rumor about W. F Libby's 14C dating system. Drawing principally from primary sources for the first time, integrated with literature from the history and sociology of science, new and interpretative information is offered relative to several topics. They include: (1) the profession's inefficient communication networks and their influence on the year-long course of truncated dialogue about purported radioactive dating investigations afoot; (2) the divergent ways in which competing factions of elite specialists labored to formulate strategies to address the perceived implications of Libby's novel technique; (3) the particularly important roles in this period assumed by Chicago's Robert Redfield and Fred Eggan, the R. S. Peabody Foundation's Frederick Johnson, and the Viking Fund's Paul Fejos, among others; (4) the degree and manner in which the effort to grapple with the 14C dating proposal was integrally connected to an ongoing campaign to enhance the professional standing of American archaeology; and (5) clear indications that some archaeologists exhibited ambivalence, if not resistance, to the prospect of "physics" intruding into their domain.

A novel technique was recently introduced in our laboratories for the measurement of the compressive strength of single fibres, based on a modified configuration of the single fibre composite fragmentation test. In particular, the effect of the length of the embedded fibre on its compressive strength was assessed for the first time, based on Weibull statistics considerations. Moreover, during the sample manufacturing stage, a fibre can break in compression due to induced cooling stresses, rather than mechanical stresses, which can be determined from the fragmentation phenomenon. In this note, improved analyses of such compressive fragmentation effects are presented and discussed.
