A number of researchers studying permutation statistics on the symmetric group Sn have considered pairs (x, Y), where x is an Eulerian statistic and Y is a Mahonian statistic. Of special interest are pairs such as (des, maj), whose joint distribution on Sn is given by Carlitz’s q-Eulerian polynomials. We present a natural Eulerian statistic stc such that the pair (stc, inv) is equally distribut...

In this paper we examine the performance of a spacetime coded (STC) OFDM system. As an example, two emerging WLAN standards (IEEE 802.11a and ETSI Hiperlad2) are modified to accommodate the STC technique. Performance results using statistical multi-element channel models are compared with those using state-of-the-art indoor MIMO channel measurements. We conclude that the gap between the ideal s...

The association between blood calcium levels and electrocardiographic variables was compared in 137 normal parturient and 36 peripartum recumbent Holstein cows to determine whether hypocalcemia in peripartum dairy cows can be rapidly diagnosed using electrocardiograph. Inverse of STc (ST peak interval/SS interval(0.5)) and blood ionized calcium or serum calcium concentrations were strongly corr...

INTRODUCTION Oscillating the head about a spatial horizontal axis activates both the vertical semicircular canals (VC) and the otolith organs. It is generally assumed that in-phase modulation of unit firing rate (FR) with head position indicates convergent otolith input, while in-phase modulation with head velocity indicates VC input. The amplitude of FR modulation depends on head orientation i...

Subtotal cystectomy (STC; surgical removal of ∼75% of the rat urinary bladder) elicits a robust proliferative response resulting in complete structural and functional bladder regeneration within 8-weeks. The goal of these studies was to characterize the early cellular response that mediates this regenerative phenomenon, which is unique among mammalian organ systems. STC was performed on eightee...

Stanniocalcin (STC) is a calcium- and phosphate-regulating hormone produced in bony fish by the corpuscles of Stannius, which are located close to the kidney. It is a major antihypercalcemic hormone in fish. As the corpuscles of Stannius are absent, and antihypercalcemic hormones are basically not necessary, in mammals, the discovery of a mammalian homolog, STC1, was surprising and intriguing. ...

Running Title: STC-1 and mammary gland function Abstract During pregnancy and lactation in rodents, STC-1 production by the ovaries is upregulated markedly and released into the circulation. The mammary glands are one target of this systemically delivered hormone. The purpose of this study was to lower serum levels of STC-1 in lactating mice through passive immunization, so as to monitor the ef...

We describe in this paper two on-line algorithms for covering planar areas by a square-shaped tool attached to a mobile robot. Let D be the tool size. The algorithms, called Spanning Tree Covering (STC) algorithms, incrementally subdivide the planar area into a grid of D-size cells, while following a spanning tree of a grid graph whose nodes are 2D-size cells. The two STC algorithms cover gener...

We study a natural problem in graph sparsification, the Spanning Tree Congestion (STC) problem. Informally, the STC problem seeks a spanning tree with no tree-edge routing too many of the original edges. The root of this problem dates back to at least 30 years ago, motivated by applications in network design, parallel computing and circuit design. Variants of the problem have also seen algorith...

Syndrome-Trellis Code (STC) is a near-optimal convolutional method for adaptive steganography. Hitherto, the existing steganography commonly depends on carefully designed distortion cost function, which controls embedding position of message in cover signal. From another point view, we implement by improving STC coding process (named Adaptive-STC). The parity-check matrix key to encoding and ex...
