Unique Games Conjecture (UGC), proposed by [24], lies in the center of many inapproximability results. At the heart of UGC lies approximability of MAX-CUT, which is a special instance of Unique Game. [25, 29] showed that assuming Unique Games Conjecture, it is NPhard to distinguish between MAX-CUT instance that has a value 1 − ε vs. 1 − Ω( √ ε). [14] then showed a matching polynomial time algor...

A time dependent two-point correlation-function analysis of the BATSE 2B catalog nds no evidence of burst repetition. As part of this analysis, we discuss the e ects of sky exposure on the observability of burst repetition and present the equation describing the signature of burst repetition in the data. For a model of all burst repetition from a source occurring in less than ve days we derive ...

In a previous study we used event-related potentials to dissociate semantic (associative) and repetition priming when prime words were masked below (40 ms primes) and above (80 and 120 ms primes) levels of awareness (Holcomb et al., 2005). While robust priming effects were present on the N400 component regardless of the prime duration in the repetition priming experiment, in the semantic primin...

Our visual memory percepts of whether we have encountered specific objects or scenes before are hypothesized to manifest as decrements in neural responses in inferotemporal cortex (IT) with stimulus repetition. To evaluate this proposal, we recorded IT neural responses as two monkeys performed a single-exposure visual memory task designed to measure the rates of forgetting with time. We found t...

Two studies were carried out to investigate the effects of presentation of primes showing partial (word-initial) or full overlap on processing of spoken target words. The first study investigated whether time compression would interfere with lexical processing so as to elicit aphasic-like performance in non-brain-damaged subjects. The second study was designed to compare effects of item overlap...

PURPOSE To study the potential combined application of gadolinium and magnetization transfer in the MR imaging of intracranial tumors. METHODS Twenty-two patients were imaged at low field strength (0.1 T). Corresponding gradient-echo partial saturation images without and with magnetization transfer pulse were produced. Images with intermediate repetition times were obtained in 18 cases; five ...

The present text discusses the protests of 2013 in Brazil from a transpassed notion time. I suggest that past, and future be taken into account for analysis protests, which are, respectively, marked by specters, conjunctions. Indeed, carry unresolved Brazilian at same time their failure presented conjunctions determine political ideological judgments about terms present. Finally, argue were an ...

Implicit memory, including priming, can be preserved in aging and dementia despite impairment of explicit memory. To explore the neural correlates of preserved memory ability, whole-brain functional MRI (fMRI) was used during a repetition priming paradigm to study 34 young adults, 33 older adults without dementia, and 24 older adults in the early stages of dementia of the Alzheimer type (DAT). ...

Positive and negative polarity fast ionization wave discharges in nitrogen and dry air are studied in a rectangular geometry channel over a wide range of time delays between the discharge pulses, s = 10 ms to 25 ls (pulse repetition rates of m = 100 Hz– 40 kHz). The discharge is generated by alternating polarity high-voltage pulses (peak voltage 18–23 kV, pulse duration 50–60 ns). Ionization wa...
