The Diversity Multiplexing Tradeoff (DMT) [1] is a compact, yet elegant framework to capture the performance of wireless communication systems at asymptotically high signal to noise ratios (SNR). Recent application of DMT at finite SNR [2] makes the DMT a versatile framework. We have analyzed the DMT for the rate-adaptive SIMO maximal-ratio combining (SIMO-MRC) for asymptotic and non-asymptotic...

The discrete multitone modulation (DMT) systems have been widely used in various applications. The DMT system can be considered as a dual of a subband coder, obtained by using the synthesis bank as the transmitter and analysis bank as the receiver. In designing optimal subband coders, the objective is to minimize output quantization noise, whereas in the problem of designing optimal DMT system,...

In Discrete Multitone (DMT) transceivers, a time domain equalizer (TEQ) is used to shorten the effective channel impulse response such that a shorter cyclic prefix can be used. In this paper, we pose the TEQ design problem completely in the frequency domain by defining a frequency-domain weighted least squares cost function. The definition of the frequency-domain TEQ design criterion, we show, ...

Disease modifying therapies (DMTs) reduce the frequency of relapses and accumulation of disability in multiple sclerosis (MS). Long-term persistence with treatment is important to optimize treatment benefit. This long-term, cohort study was conducted at the Calgary MS Clinic. All consenting adults with relapsing-remitting MS who started either glatiramer acetate (GA) or interferon-β 1a/1b (IFN-...

BACKGROUND Adherence to disease-modifying therapies (DMTs) results in the reduction of the number and severity of relapses and delays the progression of multiple sclerosis (MS). Patients with lower adherence rates experience more inpatient visits and higher MS-related medical costs. Fingolimod, the first oral DMT approved by the US Food and Drug Administration, may improve the access and compli...

We consider a general multiple antenna network with multiple sources, multiple destinations and multiple relays in terms of the diversity-multiplexing tradeoff (DMT). We examine several subcases of this most general problem taking into account the processing capability of the relays (half-duplex or full-duplex), and the network geometry (clustered or non-clustered). We first study the multiple ...

We introduce a dynamic multiscale tree (DMT) architecture that learns how to leverage the strengths of different state-of-the-art classifiers for supervised multi-label image segmentation. Unlike previous works that simply aggregate or cascade classifiers for addressing image segmentation and labeling tasks, we propose to embed strong classifiers into a tree structure that allows bi-directional...

It is known that neither the Alamouti nor the V-BLAST scheme achieves the Zheng–Tse diversity–multiplexing tradeoff (DMT) of the multiple-input multiple-output (MIMO) channel. With respect to the DMT curve, the Alamouti scheme achieves the point corresponding to maximum diversity gain only, whereas V-BLAST meets only the point corresponding to maximum multiplexing gain. It is also known that D-...

PURPOSE To evaluate adherence to disease-modifying therapies (DMTs) among patients with multiple sclerosis (MS) initiating oral and injectable DMTs, and to estimate the impact of adherence on relapse, health resource utilization, and medical costs. PATIENTS AND METHODS Commercially insured MS patients (aged 18-65 years, two or more MS diagnoses, one or more DMT claims) with continuous eligibi...

The title co-crystal, C4H7N5·C4H10O2, crystallizes with one mol-ecule of 6-methyl-1,3,5-triazine-2,4-diamine (DMT) and one mol-ecule of butane-1,4-diol in the asymmetric unit. The DMT mol-ecules form ribbons involving centrosymmetric R2(2)(8) dimer motifs between DMT mol-ecules along the c-axis direction. These ribbons are further hydrogen bonded to each other through butane-1,4-diol, forming s...
