20100183597 | DRAK2 EXPRESSION IS ASSOCIATED WITH DIABETES - Drak2 is a member of the death-associated protein family and a serine threonine kinase. In this study, we investigated its role in beta-cell survival and diabetes. Drak2 mRNA and protein were rapidly induced in islet beta-cells after stimulation by inflammatory cytokines known to be present in type 1 diabetes. Drak2 upregulation was accompanied by increased beta-cell apoptosis, beta-cell apoptosis caused by the said stimuli was inhibited by Drak2 knockdown using siRNA. Conversely, transgenic (Tg) Drak2 overexpression led to aggravated beta-cell apoptosis triggered by the stimuli. Further in vivo experiments demonstrated that Drak2 overexpressed in Tg islets is responsible for type 1 diabetes-prone phenotype. Purified Drak2 could phosphorylate ribosomal protein S6 (p70S6) kinase in an in vitro kinase assay. Drak2 overexpression in NIT-1 cells led to enhanced p70S6 kinase phosphorylation, while Drak2 knockdown in these cells reduced it. These mechanistic studies proved that p70S6 kinase was a bona fide Drak2 substrate in vitro and in vivo. | 07-22-2010 |

Finally, the modified compensation vectors are used to derive a recovered clock signal. | 10-07-2010 |
20110255875 | DUAL RATE QPSK/TCM-QPSK OPTICAL MODULATION - The present disclosure allows for optical link capacity to be optimized based on transmission parameters, such as amplifier gain, link loss, optical signal-to-noise ratio. For example, optical signals at wavelengths that are susceptible to impairments, such as non-linear effects, or that are not adequately amplified by an optical amplifier, may be modulated in accordance with lower rate/less spectrally efficient modulation formats (“low rate formats”) that are more noise tolerant. On the other hand, those optical signals at wavelengths that are less susceptible to or do not incur such impairments may be modulated in accordance with highly spectrally efficient /higher rate modulation formats (“high rate formats”) that are more noise sensitive. Accordingly, a maximum or optimized capacity may be realized through appropriately choosing, for each channel, a particular modulation format and channel spacing. Such optimized capacity can be readily obtained with adaptive driver circuits. | 10-20-2011 |
20110274436 | OPTICAL COMMUNICATION SYSTEM - Consistent with the present disclosure a transmitter is provided that transmits data in either a “quasi-DP-BPSK” (“QDP”) mode or in a DP-QPSK mode. In the QDP mode, data bits are transmitted as changes in phase between first and second phase states along a first axis or as changes in phase between third and fourth phase states along a second axis in the IQ plane. Although the transmitter outputs an optical signal that changes in phase between each of the four states, a sequence bit identifies which axis carries the data bit. The sequence bit is one of a series of sequence bits that may be generated by a pseudo-random number generator. The series of sequence bits can be relatively long, e.g., 32 bits, to permit sufficiently random changes in the axis that carries the data. Thus, unlike conventional BPSK, in which data is transmitted between phase states along a single axis, the present disclosure provides an apparatus and related method for randomly selecting one of two axes, for example, for each transmitted bit. In the receiver, it has been observed that the MU-CMA algorithm can process data carried by optical signals in the QDP mode with relatively few errors. Thus, the same equalizer (FIR) filter may be used to process BPSK, as well as QPSK data. | 11-10-2011 |

According to one of the embodiments, the interpolation circuit includes a memory and a FIR filter circuit having filter tap coefficient values selected to provide attenuation at high frequencies to reduce aliasing noise. | 12-01-2011 |

The optical signals are converted to corresponding electrical signals, which are then subject to further processing. In particular, phase data associated with the higher order QAM constellation is processed, such that the outer points of the constellation are rotated to have the same phase as the inner points. As a result, both the inner and outer points resemble a constellation, and both may be more readily processed using feedforward or feedback carrier recovery. After such carrier recovery, the phase data is further processed so that the outer points are rotated back and the customer data can be extracted from the phase data. | 12-29-2011 |

20110268526 | Injection Molded Torque Nut with Internal Recession - A torque nut includes a threaded passageway and a groove. The groove has its opening facing the passageway. A breakaway insert having a major body portion is formed in the passageway, and a tab connected to the major body portion is formed in the groove, for example, by injection molding.

In one use, a resin component, a catalyst component and a first end of a rock-bolt are positioned in a bore hole. The torque nut is threaded onto the opposite end of the rock-bolt. Rotation of the torque nut rotates the rock-bolt, mixing the components. After the components set, increased torque is applied to the torque nut to fracture the insert and move the nut up the threaded end of the rock-bolt against roof stabilizing components. | 11-03-2011 |
