    Wideband E-shaped Patch Antennas for Advanced Wireless Terminals

    Get PDF
    Low-profile patch antennas have become ubiquitous in wireless terminals, especially as devices have become smaller and demand more functionality out of their RF subsystems. While their shape and size is attactive for many applications, their narrow bandwidth hinders their usage in many systems. With the rise of computer-aided design, many patch antenna design concepts have been presented with enhanced bandwidth capabilities. The E-shaped patch antenna, whose original shape presented in the early 2000’s resembles the letter E, offers compelling performance with reasonable manufacturing complexity. In it most basic form, this antenna was linearly polarized and either wideband or dual-band. Over the last two decades, many variations of the E-shaped patch have been presented in literature: circularly polarized, miniaturized, frequency reconfigurable, or even polarization reconfigurable. This paper summarizes these efforts in realizing novel functionalities with a relatively simple design geometry

    Chameleon masculinity: developing the British ‘population-centred’ soldier

    In this article I develop what I term chameleon masculinity as a specific form of gendered adaptation of military agency opened up by the post-9/11 shift towards ‘population-centred’ counterinsurgency and stabilisation. A gendered analysis of this carefully cultivated form of military agency is central to revealing some of the concealed embodied dynamics that challenge the hegemony of the traditional combat soldier, and in practice enables this form of war. Drawing on 18 months of anthropological fieldwork, for the most part alongside the UK’s Military Stabilisation Support Group, this research incorporates my auto-ethnography as an officer in the Royal Naval Reserves. Rather than focusing at the level of policy, strategy, and doctrine, I examine how the specialized and masculinized agency of ‘the chameleon’ translates tactically into the body of the British military stabilisation operative, showing how this is developed though intensive pre-deployment training in the UK, and embodied and practised through operational deployment in Afghanistan. This reveals the specific agency of chameleon masculinity and how its potential for inherent violence becomes deceptively ‘hidden in plain sight’

    Biceps, Bitches and Borgs: Reading <i>Jarhead</i>’s Representation of the Construction of the (Masculine) Military Body

    This paper explores the relationship between masculinity, the body and the military through a close reading of the film Jarhead. Drawing on a Foucauldian frame of analysis, we consider three performances of the masculine military body that form key aspects of the film’s representational economy: the disciplined body, an outcome of the processes of basic training; the gendered body, realized through deployment of metaphors of the feminine to strengthen the masculine conception of the military body; and the cyborgian body, the result of the man-machine interface which is rapidly developing in many militaries around the world, and which poses significant questions for performances of military masculinity. We conclude by suggesting that the film’s rendering of the material and discursive body reveals an unexpected tension between the expectations of military bodies and the lived experience of their labour. As well as augmenting empirical explorations of male-worker-bodies and analysing the occupation of soldier as requiring a unique kind of body work, our contribution to the body-organization literature turns upon the claim that docile military bodies are made fit for purpose, but may actually no longer have a purpose for which to be fit

    <p>Abstract</p> <p>Background</p> <p>The monitoring of <it>BCR-ABL </it>transcript levels by real-time quantitative polymerase chain reaction (RT-qPCR) has become important to assess minimal residual disease (MRD) and standard of care in the treatment of chronic myeloid leukemia (CML). In this study, we performed a prospective, sequential analysis using RT-qPCR monitoring of <it>BCR-ABL </it>gene rearrangements in blood samples from 91 CML patients in chronic phase (CP) who achieved complete cytogenetic remission (CCyR) and major molecular remission (MMR) throughout imatinib treatment.</p> <p>Methods</p> <p>The absolute level of <it>BCR-ABL </it>transcript from peripheral blood was serially measured every 4 to 12 weeks by RT-qPCR. Only level variations > 0.5%, according to the international scale, was considered positive. Sequential cytogenetic analysis was also performed in bone marrow samples from all patients using standard protocols.</p> <p>Results</p> <p>Based on sequential analysis of <it>BCR-ABL </it>transcripts, the 91 patients were divided into three categories: (A) 57 (62.6%) had no variation on sequential analysis; (B) 30 (32.9%) had a single positive variation result obtained in a single sample; and (C) 4 (4.39%) had variations of <it>BCR-ABL </it>transcripts in at least two consecutive samples. Of the 34 patients who had elevated levels of transcripts (group B and C), 19 (55.8%) had a < 1% of <it>BCR-ABL/BCR </it>ratio, 13 (38.2%) patients had a 1% to 10% increase and 2 patients had a >10% increase of RT-qPCR. The last two patients had lost a CCyR, and none of them showed mutations in the <it>ABL </it>gene. Transient cytogenetic alterations in Ph-negative cells were observed in five (5.5%) patients, and none of whom lost CCyR.</p> <p>Conclusions</p> <p>Despite an increase levels of <it>BCR-ABL/BCR </it>ratio variations by RT-qPCR, the majority of CML patients with MMR remained in CCyR. Thus, such single variations should neither be considered predictive of subsequent failure and nor an indication for altering imatinib dose or switching to second generation therapy. Changing of imatinib on the basis of <it>BCR-ABL/BCR</it>% sustained increase and mutational studies is a prudent approach for preserving other therapeutic options in imatinib-resistant patients.</p

    Do agile managed information systems projects fail due to a lack of emotional intelligence?

    YesAgile development methodologies (ADM) have become a widely implemented project management approach in Information Systems (IS). Yet, along with its growing popularity, the amount of concerns raised in regard to human related challenges caused by applyingADMare rapidly increasing. Nevertheless, the extant scholarly literature has neglected to identify the primary origins and reasons of these challenges. The purpose of this study is therefore to examine if these human related challenges are related to a lack of Emotional Intelligence (EI) by means of a quantitative approach. Froma sample of 194 agile practitioners, EI was found to be significantly correlated to human related challenges in agile teams in terms of anxiety, motivation, mutual trust and communication competence. Hence, these findings offer important new knowledge for IS-scholars, project managers and human resource practitioners, about the vital role of EI for staffing and training of agile managed IS-projects
