100 Gbit/s serial transmission using a silicon-organic hybrid (SOH) modulator and a duobinary driver IC
100 Gbit/s three-level (50 Gbit/s 00K) signals are generated using a silicon-organic hybrid modulator and a BiCMOS duobinary driver IC at a BER of 8.5x10(-5)(<10(-12)). We demonstrate dispersion-compensated transmission over 5 km
Temperature and force dependence of nanoscale electron transport via the Cu protein Azurin
The mechanisms of solid-state electron transport (ETp) via a monolayer of
immobilized Azurin (Az) was examined by conducting probe atomic force
microscopy (CP-AFM), both as function of temperature (248 - 373K) and of
applied tip force (6-12 nN). By varying both temperature and force in CP-AFM,
we find that the ETp mechanism can alter with a change in the force applied via
the tip to the proteins. As the applied force increases, ETp via Az changes
from temperature-independent to thermally activated at high temperatures. This
is in contrast to the Cu-depleted form of Az (apo-Az), where increasing the
applied force causes only small quantitative effects, that fit with a decrease
in electrode spacing. At low force ETp via holo-Az is temperature-independent
and thermally activated via apo-Az. This observation agrees with
macroscopic-scale measurements, thus confirming that the difference in ETp
dependence on temperature between holo- and apo-Az is an inherent one that may
reflect a difference in rigidity between the two forms. An important
implication of these results, which depend on CP-AFM measurements over a
significant temperature range, is that for ETp measurements on floppy systems,
such as proteins, the stress applied to the sample should be kept constant or,
at least controlled during measurement.Comment: 24 pages, 6 figures, plus Supporting Information with 4 pages and 2

(The Need for) A Model of Translational Mind Science Justice Research
Despite the historical importance of translational research to social psychological investigations of social justice issues, the culture and incentives of contemporary social psychology are ambivalent towards non-experimental field research. This ambivalence poses a significant impediment to social psychology’s role in societal change. This paper offers a brief history of how the field evolved from a relative emphasis on translating social psychology from the laboratory to the field (and back) to the present moment. In doing so, we enumerate the most significant impediments to contemporary translational social psychology, namely that conducting translational research often involves greater cost, greater difficulty advancing psychological theory, and more time navigating logistics compared with basic laboratory research. Finally, using the example of recent multi-investigator research on race and gender equity in policing, we outline emerging strategies for how to conduct translational research amidst contemporary impediments, and offer modest suggestions for how the field can better facilitate this kind of research in the future. Taken together this review offers a set of theoretical and practical suggestions for easing the path from research to societal change
An 800-MHz Mixed-V-T 4T IFGC Embedded DRAM in 28-nm CMOS Bulk Process for Approximate Storage Applications
Compliance and legal authority
This article addresses the question of how public compliance with the criminal law is cultivated and sustained. We first consider the empirical evidence for instrumental and normative modes of compliance and social regulation. After arguing that normative compliance with the criminal law is ethically and practically preferable to that secured by instrumental models of crime control, we outline some future directions of research into procedural justice and legitimacy
