The role of mortality awareness in hero identification

Three studies examine hypotheses derived from terror management theory to investigate the relationship between mortality concerns and hero identification. Study 1 found reminders of death, followed by a distraction task and a self-prime, led to greater inclusion of heroes in the self. Study 2 found that writing about a personal hero, but not other’s heroes or acquaintances, led to lower death-thought accessibility after being reminded of mortality. Finally, Study 3 found that after death reminders, participants led to identify with a hero exemplifying traits of legacy and/or sacrifice showed lower death thought accessibility. Findings are discussed as generative for heroism research, informing a previously overlooked motivation underlying hero identification and the existential function of such identification

A Direct Carrier I/Q Modulator for High-Speed Communication at D-Band Using 130 nm SiGe BiCMOS Technology

This paper presents a 110-170 GHz direct conversion I/Q modulator realized in 130 nm SiGe BiCMOS technology with ft/fmax values of 250 GHz/ 370 GHz. The design is based on double-balanced Gilbert mixer cells with on-chip quadrature LO phase shifter and RF balun. In single-sideband operation, the modulator exhibits up to 9.5 dB conversion gain and has measured 3 dB IF bandwidth of 12 GHz. The measured image rejection ratio and LO to RF isolation are as high as 20 dB and 31 dB respectively. Meas-ured input P1dB is -17 dBm at 127 GHz output. The DC power con-sumption is 53 mW. The active chip area is 620 μm× 480 μm in-cluding the RF and LO baluns. The circuit is capable of transmit-ting more than 12 Gbit/s QPSK signal

Ivor Gurney and Sir Herbert Brewer: A misunderstood relationship?

Between 1906 and 1911, Ivor Gurney was an articled pupil of Sir Herbert Brewer, the Organist of Gloucester Cathedral, having just completed a successful career as one of Brewer’s cathedral choristers. During his time as a chorister he had regularly been given solos, including most notably as a last minute stand in soloist in a major concert during the 1904 Three Choirs Festival, and he had also been appointed the choir’s ‘first chorister’ in 1905. He was therefore already a gifted musician and it was no surprise that Brewer agreed to take him on as a pupil. At this time in 1906, Brewer — himself a former Gloucester chorister and articled pupil of one of his Gloucester predecessors, C. H. Lloyd — had been the cathedral organist for nearly ten years, and would stay in post until his death in 1928. My recent research for a University of Gloucestershire MA examined his place in British music history, his educational philosophy, and the effect he had on the careers of his teenage articled pupils (of which he generally had a few at any one time). It was initially prompted by a sense that he had been given a ‘raw deal’ by the biographers of his more well-known articled pupils, including Gurney, who tend to disparage or play down his role. His other notable pupils included Herbert Howells and Ivor Novello. Writing of Gurney, Michael Hurd (1978) was particularly hard on Brewer and treats the musical life of Gloucester Cathedral rather disparagingly. Hurd reports that Brewer ‘does not appear to have been enthusiastic, (as a teacher of Gurney) but duly instructed his wayward pupil in the mysteries of harmony and counterpoint, piano and organ.’ One of my main sources was Brewer’s own extensive published memoirs, but, useful as they are, they do not include anything on Gurney or his relationship with him

Requirement of a 5′-Proximal Linear Sequence on Minus Strands for Plus-Strand Synthesis of a Satellite RNA Associated with Turnip Crinkle Virus

AbstractViral RNA replication begins with specific recognition of cis-acting RNA elements by the viral RNA-dependent RNA polymerase (RdRp) and/or associated host factors. A short RNA element (3′-AACCCCUGGGAGGC) located 41 bases from the 5′ end of minus strands of satellite RNA C (satC), a 356-base subviral RNA naturally associated with turnip crinkle virus (TCV), was previously identified as important for plus-strand synthesis using an in vitro RdRp assay (H. Guan, C. Song, A. E. Simon, 1997, RNA 3, 1401–1412). To examine the functional significance of this element in RNA replication, mutations were introduced into the consecutive C residues in the element. A single mutation of the 3′-most C residue resulted in undetectable levels of satC plus strands when transcripts were assayed in protoplasts and suppressed transcription directed by the element in vitro. However, satC minus strands were detectable at 6 h postinoculation (hpi) of protoplasts, accumulating to about 10% of wild-type levels at 24 hpi. This mutation, when in the plus-sense orientation, had little or no effect on minus-strand synthesis from full-length satC plus strands in vitro, suggesting that the 5′-proximal RNA element is required for satC plus-strand synthesis. In addition, in vivo genetic selection revealed a strict requirement for 10 of the 14 nucleotides of the element, indicating that the primary sequence is essential for RNA accumulation

A Fully integrated D-band Direct-Conversion I/Q Transmitter and Receiver Chipset in SiGe BiCMOS Technology

This paper presents design and characterization of single-chip 110-170 GHz (D-band) direct conversion in-phase/quadrature-phase (I/Q) transmitter and receiver monolithic microwave integrated circuits (MMICs), realized in a 130 nm SiGe BiCMOS process with ft/fmax of 250 GHz/370 GHz. The chipset is suitable for low power wideband communication and can be used in both homodyne and heterodyne architectures. The Transmitter chip consists of a six-stage power amplifier, an I/Q modulator, and a LO multiplier chain. The LO multiplier chain consists of frequency sixtupler followed by a two-stage amplifier. It exhibits a single sideband conversion gain of 23 dB and saturated output power of 0 dBm. The 3 dB RF bandwidth is 31 GHz from 114 to 145 GHz. The receiver includes a low noise amplifier, I/Q demodulator and x6 multiplier chain at the LO port. The receiver provides a conversion gain of 27 dB and has a noise figure of 10 dB. It has 3 dB RF bandwidth of 28 GHz from 112-140 GHz. The transmitter and receiver have dc power consumption of 240 mW and 280 mW, respectively. The chip area of each transmitter and receiver circuit is 1.4 mm x 1.1 mm
