Some Introductory Notes on the Development and Characteristics of Sabah Malay

This is a preliminary description of the Malay variety used as a lingua franca in the Malaysian state of Sabah at the northernmost top of Borneo. The paper discusses a number of common linguistic features that distinguish Sabah Malay from other Malay varieties and analyses these features from a historical linguistic perspective. While it is argued that Sabah Malay has a close historical relation with other Malay dialects spoken in Borneo, especially Brunei Malay, the vernacular is also influenced phonologically and lexically by Sabah\u27s indigenous and immigrant speech communities. Words and sentences recorded or elicited during fieldwork in various parts of Sabah illustrate these points

Induction of NF-κB by the Akt/PKB kinase

AbstractThe serine/threonine kinase Akt (also known as protein kinase B, PKB) is activated by numerous growth-factor and immune receptors through lipid products of phosphatidylinositol (PI) 3-kinase. Akt can couple to pathways that regulate glucose metabolism or cell survival [1]. Akt can also regulate several transcription factors, including E2F, CREB, and the Forkhead family member Daf-16 [2–4]. Here, we show that Akt can regulate signaling pathways that lead to induction of the NF-κB family of transcription factors in the Jurkat T-cell line. This induction occurs, at least in part, at the level of degradation of the NF-κB inhibitor IκB, and is specific for NF-κB, as other inducible transcription factors are not affected by Akt overexpression. Furthermore, the effect requires the kinase activity and pleckstrin homology (PH) domain of Akt. Also, Akt does not act alone to induce cytokine promoters and NF-κB reporters, because signals from other pathways are required to observe the effect. These studies uncover a previously unappreciated connection between Akt and NF-κB induction that could have implications for the control of T-cell growth and survival

Stability of the nonlinear dynamics of an optically injected VCSEL

Automated protocols have been developed to characterize time series data in terms of stability. These techniques are applied to the output power time series of an optically injected vertical cavity surface emitting laser (VCSEL) subject to varying injection strength and optical frequency detuning between master and slave lasers. Dynamic maps, generated from high resolution, computer controlled experiments, identify regions of dynamic instability in the parameter space. © 2012 Optical Society of America

IL-17 Signaling triggers degradation of the constitutive NF-κB inhibitor ABIN-1

IL-17 activates NF-κB and induces expression of proinflammatory genes. IL-17 drives disease in autoimmune conditions, and anti–IL-17 Abs have shown impressive success in the clinic. Although produced by lymphocytes, IL-17 predominantly signals in fibroblasts and epithelial cells. IL-17–driven inflammation is kept in check by negative feedback signaling molecules, including the ubiquitin editing enzyme A20, whose gene TNFAIP3 is linked to autoimmune disease susceptibility. The A20 binding inhibitor of NF-κB activation 1 (ABIN-1) is an A20-binding protein encoded by the TNIP1 gene, which is also linked to autoimmune disease susceptibility including psoriasis. Accordingly, we hypothesized that ABIN-1 might play a role in negatively regulating IL-17 signaling activity. Indeed, ABIN-1 enhanced both tonic and IL-17–dependent NF-κB signaling in IL-17–responsive fibroblast cells. Interestingly, the inhibitory activities of ABIN-1 on IL-17 signaling were independent of A20. ABIN-1 is a known NF-κB target gene, and we found that IL-17–induced activation of NF-κB led to enhanced ABIN-1 mRNA expression and promoter activity. Surprisingly, however, the ABIN-1 protein was inducibly degraded following IL-17 signaling in a proteasome-dependent manner. Thus, ABIN-1, acting independently of A20, restricts both baseline and IL-17–induced inflammatory gene expression. We conclude that IL-17–induced signals lead to degradation of ABIN-1, thereby releasing a constitutive cellular brake on NF-κB activation

Indirect Interaction of Solid-State Qubits via Two-Dimensional Electron Gas

We propose a mechanism of long-range coherent coupling between nuclear spins to be used as qubits in solid-state semiconductor-heterojunction quantum information processing devices. The coupling is via localized donor electrons which in turn interact with the two-dimensional electron gas. An effective two-spin interaction Hamiltonian is derived and the coupling strength is evaluated. We also discuss mechanisms of qubit decoherence and consider possibilities for gate control of the interaction between neighboring qubits. The resulting quantum computing scheme retains all the gate-control and measurement aspects of earlier approaches, but allows qubit spacing at distances of order 100nm, attainable with the present-day semiconductor device technologies.Comment: 12 pages in plain Te

Opportunities From the Digital Revolution: Implications for Researching, Publishing, and Consuming Qualitative Research

In the 1990s, the term 'online' research emerged as a new and vibrant suite of methods, focused on exploitation of sources not collected by traditional social science methods. Today, at least one part of the research life cycle is likely to be carried out 'online,' from data collection through to publishing. In this article, we seek to understand emergent modes of doing and reporting qualitative research 'online.' With a greater freedom now to term oneself a 'researcher,' what opportunities and problems do working with online data sources bring? We explore implications of emerging requirements to submit supporting data for social science journal articles and question whether these demands might disrupt the very nature of and identity of qualitative research. Finally, we examine more recent forms of publishing and communicating research that support outputs where data play an integral role in elucidating context and enhancing the reading experience

The First Extrasolar Planet Discovered with a New Generation High Throughput Doppler Instrument

We report the detection of the first extrasolar planet, ET-1 (HD 102195b), using the Exoplanet Tracker (ET), a new generation Doppler instrument. The planet orbits HD 102195, a young star with solar metallicity that may be part of the local association. The planet imparts radial velocity variability to the star with a semiamplitude of $63.4\pm2.0$ m s$^{-1}$ and a period of 4.11 days. The planetary minimum mass ($m \sin i$) is $0.488\pm0.015$ $M_J$.Comment: 42 pages, 11 figures and 5 tables, Accepted for publication in Ap
