Intimate war
Contending that domestic violence and modern international warfare are part of a single complex of violence, this paper identifies their shared intimate dynamics. Both violences operate through emotional and psychological registers that are as central to their effectiveness as incidents of direct physical harm. While these dynamics are intimate, they are present across scale, and read here through a feminist lens on intimacy-geopolitics where neither framing has primacy. Research on the connections between domestic violence and international warfare is longstanding, most recently highlighting how intimate violence is produced within warzones. The analysis here begins instead from intimate dynamics, to draw out the warlike nature of domestic violence in peacetime. Tactics of modern warfare are juxtaposed with the dynamics of domestic violence in suburban Scottish homes: shock and awe, hearts and minds, cultural and psychological occupation, just war and collateral damage. Resisting the temptation to regard domestic violence as everyday militarism, the relation is rotated: both violences continuously wind through the intimate-geopolitical. This spatial reconfiguration is structured by gender, race, class, nation and citizenship, resulting in uneven impacts from all kinds of intimate war. The interweaving of military and intimate themes is intended as a casting-off point for progressing political geographies that are attentive to intimacy as foundational in the workings of power across scale
An evaluation of the ATM man/machine interface. Phase 3: Analysis of SL-3 and SL-4 data
The functional adequacy of human factored crew operated systems under operational zero-gravity conditions is considered. Skylab ATM experiment operations generated sufficient telemetry and voice transcript data to support such an assessment effort. Discussions are presented pertaining to the methodology and procedures used to evaluate the hardware, training and directive aspects of Skylab 3 and Skylab 4 manned ATM experiment operations
Teleosemantics and the hard problem of content
Hutto and Myin claim that teleosemantics cannot account for mental content. In their view, teleosemantics accounts for a poorer kind of relation between cognitive states and the world but lacks the theoretical tools to account for a richer kind. We show that their objection imposes two criteria on theories of content: a truth-evaluable criterion and an intensionality criterion. For the objection to go through, teleosemantics must be subject to both these criteria and must fail to satisfy them. We argue that teleosemantics meets the truth-evaluable criterion and is not required to meet the intensionality criterion. We conclude that Hutto and Myin’s objection fails
Teleosemantics and the free energy principle
The free energy principle is notoriously difficult to understand. In this paper, we relate the principle to a framework that philosophers of biology are familiar with: Ruth Millikan’s teleosemantics. We argue that: (i) systems that minimise free energy are systems with a proper function; and (ii) Karl Friston’s notion of implicit modelling can be understood in terms of Millikan’s notion of mapping relations. Our analysis reveals some surprising formal similarities between the two frameworks, and suggests interesting lines of future research. We hope this will aid further philosophical evaluation of the free energy principle
Jensen-Feynman approach to the statistics of interacting electrons
Faussurier et al. [Phys. Rev. E 65, 016403 (2001)] proposed to use a
variational principle relying on Jensen-Feynman (or Gibbs-Bogoliubov)
inequality in order to optimize the accounting for two-particle interactions in
the calculation of canonical partition functions. It consists in a
decomposition into a reference electron system and a first-order correction.
The procedure appears to be very efficient in order to evaluate the free energy
and the orbital populations. In this work, we present numerical applications of
the method and propose to extend it using a reference energy which includes the
interaction between two electrons inside a given orbital. This is possible
thanks to our efficient recursion relation for the calculation of partition
functions. We also show that a linear reference energy, however, is usually
sufficient to achieve a good precision and that the most promising way to
improve the approach of Faussurier et al. is to apply Jensen's inequality to a
more convenient convex function.Comment: submitted to Physical Review
Integrated infrared and visible image sensors
Semiconductor imaging devices integrating an array of visible detectors and another array of infrared detectors into a single module to simultaneously detect both the visible and infrared radiation of an input image. The visible detectors and the infrared detectors may be formed either on two separate substrates or on the same substrate by interleaving visible and infrared detectors
The Histone 3'-Terminal Stem-Loop-Binding Protein Enhances Translation through a Functional and Physical Interaction with Eukaryotic Initiation Factor 4G (eIF4G) and eIF3
Metazoan cell cycle-regulated histone mRNAs are unique cellular mRNAs in that they terminate in a highly conserved stem-loop structure instead of a poly(A) tail. Not only is the stem-loop structure necessary for 3'-end formation but it regulates the stability and translational efficiency of histone mRNAs. The histone stem-loop structure is recognized by the stem-loop-binding protein (SLBP), which is required for the regulation of mRNA processing and turnover. In this study, we show that SLBP is required for the translation of mRNAs containing the histone stem-loop structure. Moreover, we show that the translation of mRNAs ending in the histone stem-loop is stimulated in Saccharomyces cerevisiae cells expressing mammalian SLBP. The translational function of SLBP genetically required eukaryotic initiation factor 4E (eIF4E), eIF4G, and eIF3, and expressed SLBP coisolated with S. cerevisiae initiation factor complexes that bound the 5' cap in a manner dependent on eIF4G and eIF3. Furthermore, eIF4G coimmunoprecipitated with endogenous SLBP in mammalian cell extracts and recombinant SLBP and eIF4G coisolated. These data indicate that SLBP stimulates the translation of histone mRNAs through a functional interaction with both the mRNA stem-loop and the 5' cap that is mediated by eIF4G and eIF3
