Conventional face super-resolution methods, also known as face hallucination, are limited up to 2∼4× scaling factors where 4 ∼ 16 additional pixels are estimated for each given pixel. Besides, they become very fragile when the input low-resolution image size is too small that only little information is available in the input image. To address these shortcomings, we present a discriminative gene...

For many classes of symplectic manifolds, the Hamiltonian flow of a function with sufficiently large variation must have a fast periodic orbit. This principle is the base of the notion of Hofer-Zehnder capacity and some other symplectic invariants and leads to numerous results concerning existence of periodic orbits of Hamiltonian flows. Along these lines, we show that given a negatively curved...

The integration of heterogeneous networks is a trend of Fourth Generation (4G) systems. But with more integrating network technologies, bandwidth management is more complicated. This paper proposes a bandwidth management method, called Bandwidth Management and Disposition (BMD). The BMD calculates the Reword Point (RP) to quantify the Mobile Host’s (MH) requests, and calculates the Upgrade Rank...

In this paper we describe a method for learning grammars in the general framework of Harmonic Serialism (see McCarthy this volume for references and an introduction). We have two main goals. The first is to address the hidden structure problem that serial derivations introduce. The second is to address the problem of learning variation, which has yet to be confronted in this framework (see also...

IEEE 802.11v and 802.11aa are two recent amendments that define new functionalities in order to support a reliable multicast transport over wireless networks. The first amendment introduces directed multicast service (DMS). On the other hand, 802.11aa defines the groupcast with retries (GCR) service, which proposes two retransmission policies: block acknowledgement (GCR-BACK) and unsolicited re...

We present a domain theoretic characterisation of the weak instance approach to the universal relation (UR) model. This characterisation gives us a better understanding of the semantics of the UR model. In particular, we show that the representative instance is the least upper bound of a transformation function on the database, which is analogous to the well-known chase procedure. In addition, ...

It is shown by examples that the position uncertainty on a circle, proposed recently by Kowalski and Rembieli´nski [J. Phys. A 35 (2002) 1405] is not consistent with the state localization. We argue that the relevant uncertainties and uncertainty relations (UR's) on a circle are that based on the Gram-Robertson matrix. Several of these generalized UR's are displayed and related criterions for s...

Urate-lowering therapy is indispensable for the treatment of gout, but available drugs do not control serum urate levels tightly enough. Although the uricosurics benzbromarone and probenecid inhibit a urate reabsorption transporter known as renal urate transporter 1 (URAT1) and thus lower serum urate levels, they also inhibit other transporters responsible for secretion of urate into urine, whi...

BACKGROUND The agreement on agriculture and the World Trade Organization were major outcomes of the 1986-1994 Uruguay Round (UR) negotiations within the General Agreement on Tariffs and Trade (GATT). The measures under the UR were predicted to increase poverty in developing countries, a serious cause for concern since poverty alleviation is a major goal of developing countries. Thus this paper ...

BACKGROUND An accurate prediction of unplanned readmission (UR) after discharge from hospital can facilitate physician's decision making processes for providing better quality of care in geriatric patients. The objective of this study was to explore the association of cardiac autonomic functions as measured by frequency domain heart rate variability (HRV) and 14-day UR in geriatric patients. ...
