This report summarizes a software de…ned phase locked loop and its connection to standard second-order loop design parameter for a integrating VCO and DDFS frequency synthesizer. 1 Introduction Phase locked loops (PLLs) have been used since the early development of radio. Critical paper collections [1] and books [2] cover the subject matter, which includes nonlinear feedback and stochastic di¤e...

In this paper, we propose a parametric model checking algorithm for a subclass of Timed Automata called Parametric Time-Interval Automata(PTIA). In a PTIA, we can specify upperand lower-bounds of the execution time (time-interval) of each transition using parameter variables. The proposed algorithm takes two inputs, a model described in a PTIA and a property described in a PTIA accepting all in...

BACKGROUND The prognostic significance of disseminated tumor cells (DTC) in bone marrow (BM) of breast cancer patients at the time of primary diagnosis has been confirmed by a large pooled analysis. In view of the lack of early indicators for secondary adjuvant treatment, we here evaluated whether the persistence of DTCs after adjuvant therapy increases the risk of subsequent relapse and death....

Purpose. Typical treatment of retroperitoneal sarcomas (RPSs) is surgery with or without radiation therapy for localized disease. With surgery alone, local failure rates are as high as 90%; this led to radiation therapy playing an important role in the treatment of RPSs. Methods. Thirty-one patients with retroperitoneal sarcoma treated with gross total resection and radiation therapy make up th...

Current Flow Scheduling techniques in Data Center Networks(DCN) results in overloaded or underutilized links. Static flow scheduling techniques such as ECMP and VLB use hashing techniques for scheduling the flows. In case of hash collision a path gets selected number of times resulting overloading of that path and underutilization of other paths. Dynamic flow scheduling techniques like global f...

BACKGROUNDS Matrix metalloproteinase 2 (MMP-2) plays a crucial role in the progression of breast cancer (BC). The prognostic role of MMP-2 expression in BC patients has been widely reported, but the results were inconsistent. Thus, a meta-analysis was conducted to gain a better insight into the impact of MMP-2 expression on survival and clinicopathological features of BC patients. METHODS Ide...

Consider a communication network. Our goal is to equip the set of processors in the network with a control algorithm that will allow a processor in the network to effect a depth-first traversal through the graph underlying the network, using messages. The output of the algorithm is a depthfirst-search (DFS) tree of the graph underlying the network, kept in a distributed fashion, i.e., at the en...

DDFS (Direct Digital Frequency Synthesizer) is a new technique of frequency synthesizes which introduces the advanced digital processing theory into frequency synthesis. A direct digital frequency synthesizer is composed of a phase accumulator, an adder, an ROM for wave pattern saving, a D/A converter and a LPF (low pass filter). With the rapid development of VLSI, the speed of algorithm is req...

After doing a literature survey on the DFFS algorithms ([1] ~ [6]) proposed in recent years (after 2000), we select the algorithm presented in [1] to be implemented in our project. Compared with other algorithm we study in the literature survey, the selected algorithm is able to achieve highest clock frequency and spurious free dynamic range (SFDR) while requires a modest implementation complex...

Background: The RSSearchTM Registry is a multi-institutional, observational, ongoing registry established to standardize data collection from patients treated with stereotactic radiosurgery (SRS) and/or stereotactic body radiotherapy (SBRT). This report describes the design, patient demographics, lesion characteristics, and SRS/SBRT treatment patterns in RSSearchTM. Illustrative patient-related...
