We discuss a new optimisation for recursive functions yielding multiple results in tuples for lazy functional languages, like Clean and Haskell. This optimisation improves the execution time of such functions and also reduces the amount of memory allocated in the heap by these functions, which reduces garbage collection costs. In some cases execution time is improved by more than a factor of tw...

The products of the Polycomb group of genes are cooperatively involved in repressing expression of homeotic selector genes outside of their appropriate anterior/posterior boundaries. Loss of maternal and/or zygotic function of Polycomb group genes results in the ectopic expression of both Antennapedia Complex and Bithorax Complex genes. The products of the trithorax group of genes are cooperati...

We introduce a new method — the group Dantzig selector — for high dimensional sparse regression with group structure, which has a convincing theory about why utilizing the group structure can be beneficial. Under a group restricted isometry condition, we obtain a significantly improved nonasymptotic `2-norm bound over the basis pursuit or the Dantzig selector which ignores the group structure. ...

Mobile location estimation is becoming an important value-added service for a mobile phone operator. It is well-known that GPS can provide an accurate location estimation. But it is also a known fact that GPS does not perform well in urban areas like downtown New York and cities like Hong Kong. Then many mobile location estimation approaches based on the cellular radio networks have been propos...

In this paper an efficient face candidates selector is proposed for face detection tasks in still gray level images. The proposed method acts as a selective attentional mechanism. Eye-analogue segments at a given scale are discovered by finding regions which are roughly as large as real eyes and are darker than their neighborhoods. Then a pair of eye-analogue segments are hypothesized to be eye...

We demonstrate a selector device with excellent performances (J MAX > 10 7 A/cm 2 , switching speed < 20ns) at the 30nm cell size. Furthermore, these promising device characteristics were achieved in a fully CMOS compatible stack (W/Ta 2 O 5 /TaO x /TiO 2 /TiN) with extremely thin oxide layer (< 10nm). Through the comprehensive understanding on the exponential I-V curve, the effect of intrinsic...

This paperpnsenb a radical-partitioned neural network system using a modified Sigmoid fvnction and a weight-dotted radical selector f o r large-volume Chinese characters recognition VLSI. Wiih a modified Sigmoid function and the weight-dotted radical selector, the recognition rate of 1000 radical-partitioned Chinese characters can be enhanced to 90% from 70% for the input samples with 15% rando...

This paper describes a high-speed GaAs MESFET digital IC design for optical communication systems. We propose novel circuit configurations of a selector and a static delayed flip-flop which are key elements to perform high-speed digital functions. Employing these new design, the selector IC and static decision IC fabricated with 0.12-μm GaAs MESFET operated up to 44 Gbit/s and 22 Gbit/s, respec...

A sequence of objects with independent, identically distributed qualities is presented to a selector who must choose two on-line, i.e. without anticipation or recall. The selector’s aim is to obtain a satisfactory pair as quickly as possible. Two versions of the problem are considered, and optimal selection rules are derived and compared. An investigation is also made of a heuristic rule suitab...

The earliest step in creating the cerebral cortex is the specification of neuroepithelium to a cortical fate. Using mouse genetic mosaics and timed inactivations, we demonstrated that Lhx2 acts as a classic selector gene and essential intrinsic determinant of cortical identity. Lhx2 selector activity is restricted to an early critical period when stem cells comprise the cortical neuroepithelium...
