Epitaxial growth of CoSi2 on hydrogen-terminated Si(001)
We demonstrate that CoSi2 grows epitaxially on H-terminated Si(001) and present the growth mechanism. It was found that direct reaction of Co with Si is suppressed on H-terminated Si below 400 °C. Thus, the hydrogen at the Co/Si interface hinders the formation of Co2Si and CoSi. Upon thermal desorption of hydrogen at around 400–550 °C, CoSi2, which is closely lattice-matched to Si(001), grows on Si(001) and thus, thin epitaxial CoSi2 films are formed on Si(001). The {111}-faceting was completely suppressed in the epitaxial CoSi2/Si(001), leading to the atomically flat interface

The pion-nucleon scattering lengths from pionic deuterium
We use the framework of effective field theories to discuss the determination
of the S-wave \pi N scattering lengths from the recent high-precision
measurements of pionic deuterium observables. The theoretical analysis proceeds
in several steps. Initially, the precise value of the pion-deuteron scattering
length a_{\pi d} is extracted from the data. Next, a_{\pi d} is related to the
S-wave \pi N scattering lengths a_+ and a_-. We discuss the use of this
information for constraining the values of these scattering lengths in the full
analysis, which also includes the input from the pionic hydrogen energy shift
and width measurements, and throughly investigate the accuracy limits for this
procedure. In this paper, we also give a detailed comparison to other effective
field theory approaches, as well as with the earlier work on the subject,
carried out within the potential model and multiple scattering framework.Comment: The replacement includes an erratum, which is published in Eur. Phys.

Effects of Second Phase Morphology on Deep Drawability of TRIP-aided Dual-phase Sheet Steels
applicationEffects of retained austenite parameters on the deep drawability in high-strength TRIP-aided dual-phase (TDP) sheet steels with different silicon and manganese contents were investigated. The deep drawability evaluated with a limiting drawing ratio (LDR) was affected by volume fraction of the retained austenite rather than by its stability and morphology. Namely, the higher the volume fraction of the retained austenite, the larger the strength-deepdrawability balance, i.e., the product of tensile strength and LDR. The excellent deep drawability was caused by large local necking resistance at the cup wall just above the punch bottom due to "the transformation hardening" and "the stress relaxation" resulting from the strain-induced martensite transformation, as well as a low punch force of the shrinking flange.departmental bulletin pape

Catálogo Taxonômico da Fauna do Brasil: setting the baseline knowledge on the animal diversity in Brazil
The limited temporal completeness and taxonomic accuracy of species lists, made available in a traditional manner in scientific publications, has always represented a problem. These lists are invariably limited to a few taxonomic groups and do not represent up-to-date knowledge of all species and classification. In this context, the B Brazilian megadiverse fauna is no exception, and the Catálogo Taxonômico da Fauna do Brasil (CTFB) (h[p://fauna.jbrj.gov.br/), made public in 2015, represents a database on biodiversity anchored on a list of valid and expertly recognized scientific names of animals in Brazil. The CTFB is updated in near real time by a team of more than 800 specialists. By January 1, 2024, the CTFB compiled 133,691 nominal species, with 125,138 that were considered valid. Most of the valid species were arthropods (82.3%, with more than 102,000 species) and chordates (7.69%, with over 11,000 species). These taxa were followed by a cluster composed of Mollusca (3,567 species), Platyhelminthes (2,292 species), Annelida (1,833 species), and Nematoda (1,447 species). All remaining groups had less than 1,000 species reported in Brazil, with Cnidaria (831 species), Porifera (628 species), Rotifera (606 species), and Bryozoa (520 species) representing those with more than 500 species. Analysis of the CTFB database can facilitate and direct efforts towards the discovery of new species in Brazil, but it is also fundamental in providing the best available list of valid nominal species to 6 users, including those in science, health, conservation efforts, and any initiative involving animals. The importance of the CTFB is evidenced by the elevated number of citations in the scientific literature in diverse areas of biology, law, anthropology, education, forensic science, and veterinary science, among others
Do the Internet Security Alerts Have an Impact on Lowering ccTLD Security Risks?
Despite all the security measures to build a safely networked world there are innumerable loopholes for malicious activity. One of the countermeasures to fight such malicious activities is to issue security alerts. The purpose of this paper is to see if there is significant impact by these security alerts; to best of our knowledge, this is the first statistical study to understand such impact of Internet security alerts. For the analysis, this paper looks at two of the most malicious security alerts, the Phishing and Spam, issued by two well-known sources. The statistical analysis concludes that for Phishing, the security alerts indeed has a significant positive impact at ccTLD2 level. For Spam, the security alert data issued by reputed organizations is less frequent. As such, the available data is limited; and, our statistical analysis concludes that Spam is still out of control at ccTDL level. However, considering the significant positive impact on Phishing due to security alerts, it seems reasonable to suggest that the agencies issuing security alerts must be more serious and regular in publishing the rankings than at present.departmental bulletin pape
