Fibrillar macromolecules are long, linear structures that have helical symmetry. A technique called X-ray fiber diffraction (XRFD) is often used to help solve the three-dimensional structure of fibrillar macromolecules. Models of fibrillar structure, built de novo, using homologs or using experimental data derived from other methods should be compared to this experimental XRFD data to test and ref

Gender assignment in languages with a gender system is a complex issue, as this can be influenced by both semantic, morphological, and phonological factors (Corbett, 1991, 2013; Corbett & Fraser, 2000). Many Indo-European languages possess a three-gender system, which distinguishes masculine, feminine, and neuter gender. Whereas this system is preserved in several Indo-European branches, it ha

Precipitation and recovery of precipitates is one of the unit operations in chemical engineering that can be operated on a large scale. Experiences from the area of biotechnology have clearly shown that there is not enough selectivity in the precipitation methods used to be able to separate, for example, complex mixtures of proteins from cell homogenates. Moreover, methods to precipitate proteins

Two new paired domain genes of Drosophila, Pox meso and Pox neuro, are described. In contrast to the previously isolated paired domain gnees, paired and gooseberry, which contain both a paired and a homeodomain (PHox genes), Pox meso and Pox neuro possess no homeodomain. Evidence suggesting that the new genes encode tissue-specific transcriptional factors and belong to the same regulatory cascade

Testicular microlithiasis (TM) has been reported in up to 46% of men with testicular cancer. This has given rise to the suspicion that TM is a premalignant condition. In studies of healthy men there is, however, no association between TM and development of cancer. Nonetheless, patients with TM and contralateral testicular cancer, testicular atrophy, inhomogeneous parenchyma, infertility or a histo

The main contribution of this article is a rethinking of the peace concept, geared towards the creation of a framework for the analysis of agonistic peace. The literature on agonistic peace has thus far been elaborate in terms of theoretical sophistication. However, the dearth of empirical research on the concept is quite remarkable. This study takes that lacuna as a starting point for the groundi

Using resources shared within a social group – either in a cooperative or a competitive way - requires keeping track of own and others’ actions, which, in turn, requires well-developed short-term memory. Although short-term memory has been tested in social mammal species, little is known about this capacity in highly social birds, such as ravens. We compared ravens (Corvus corax) with humans in sp

COVID-19 has turned our lives upside down. The first lockdown occurred in Italy in the spring of 2020, drastically disrupting people’s daily schedules, work schedules, socialisation, and relationships with co-workers, family and friends. To overcome physical isolation, collect impressions and keep a record of the period, the “How are you?” online questionnaire has been designed as a potential conv

Memristors implemented as resistive random-access memories (RRAMs) owing to their low power consumption, scalability, and speed are promising candidates for in-memory computing and neuromorphic applications. Moreover, a vertical 3D implementation of RRAMs enables high-density crossbar arrays at a minimal footprint. Co-integrated III–V vertical gate-all-around MOSFET selectors in a one-transistor-o

The Swedish electric vehicle fleet is rapidly growing, creating a need to include their charging demand in future grid planning. Charging stations are often placed based on the needs of the transport system, and the grid connection is considered at a later stage with long lead times. This study proposes selecting charging locations based on grid capacity. Doing this by probabilistic load flow requ

The colophon in Ps 72:20 has long been puzzling psalm scholars. It reads כלו תפלות דוד בן־ישי—the prayers of David, son of Jesse, are ended—and as such it raises a number of questions. The first observation to be made is that the word תפלה is used, not תהלה. That this is a potential problem is clear already in the LXX, where תפלה is corrected to ὕμνοι. Secondly, the claim that the prayers of David
