Abstract

We consider a content delivery problem in which jobs are processed in batches and may abandon before their service has been initiated. We model the problem as a Markovian single-server queue and analyze two different settings: (1) the system is cleared as soon as the server is activated, i.e., service rate mu = infinity, and (2) the service speed is exponentially distributed with rate mu < infinity. The objective is to determine the optimal clearing strategy that minimizes the average cost incurred by holding jobs in the queue, having jobs renege, and performing setups. This last cost is incurred upon activation of the server in the case mu = infinity, and per unit of time the server is active otherwise. Our first contribution is to prove that policies of threshold type are optimal in both frameworks. In order to do so we have used the Smoothed Rate Truncation method which overcomes the problem arising from unbounded transition rates. For our second contribution, we derive the steady-state job-length distribution under threshold policies. The latter yields a characterization of the optimal threshold strategy, which can be easily implemented. Finally, we present numerical results for our solution across a wide range of parameters. We show that the performance of nonoptimal threshold policies can be very poor, which highlights the importance of computing the optimal threshold.

Abstract

Energy storage devices (ESDs) have the potential to revolutionize the electricity grid by allowing the smoothing of variable-energy generator output and the time-shifting of demand away from peak times. A common approach to study the impact of ESDs on energy systems is by modeling them as electric circuits in simulations. Although recent circuit models are becoming more accurate, to obtain statistically valid results, extensive simulations need to be run. In some cases, existing datasets are not large enough to obtain statistically significant results. The impact of ESDs on energy systems has also been recently studied using analytical methods, but usually by assuming ideal ESD behavior, such as infinite ESD charging and discharging rates, and zero self-discharge. However, real-life ESDs are far from ideal. We investigate the effect of nonideal ESD behavior on system performance, presenting an analytical ESD model that retains much of the simplicity of an ideal ESD, yet captures many (though not all) nonideal behaviors for a class of ESDs that includes all battery technologies and compressed air energy storage systems. This allows us to compute performance bounds for systems with nonideal ESDs using standard teletraffic techniques. We provide performance results for five widely used ESD technologies and show that our models can closely approximate numerically computed performance bounds.

Abstract

The focus of our work is the use of an energy storage system (ESS) to integrate solar energy generators into the electrical grid. Although, in theory, an ESS allows intermittent solar power to be shaped to meet any desired load profile, in practice, parsimonious ESS dimensioning is challenging due to the stochastic nature of generation and load and the diversity and high cost of storage technologies. Existing methods for ESS sizing are based either on simulation or analysis, both of which have shortcomings. Simulation methods are computationally expensive and depend on the availability of extensive data traces. Existing analytical methods tend to be conservative, overestimating expensive storage requirements. Our key insight is that solar power fluctuations arise at a few distinct time scales. We separately model fluctuations in each time scale, which allows us to accurately estimate ESS performance and efficiently size an ESS. Numerical examples with real data traces show that our model and analysis are tight

Abstract

The wide range of performance characteristics of storage technologies motivates the use of a hybrid energy storage systems (HESS) that combines the best features of multiple technologies. However, HESS design is complex, in that it involves the choice of storage technologies, the sizing of each storage element, and deciding when to charge and discharge each underlying storage element (the operating strategy.We formulate the problem of jointly optimizing the sizing and the operating strategy of an HESS that can be used for a large class of applications and storage technologies. Instead of a single set of storage element sizes, our approach determines the Pareto-optimal frontier of the sizes of the storage elements along with the corresponding optimal operating strategy. Thus, as long as the performance objective of a storage application (such as an off-grid microgrid) can be expressed as a linear combination of the underlying storage sizes, the optimal vector of storage sizes falls somewhere on this frontier. We present two case studies to illustrate our approach, demonstrating that a single storage technology is sometimes inadequate to meet application requirements, unlike an HESS designed using our approach. We also find simple, near-optimal, and practical operating strategies for these case studies, which allows us to gain several new engineering insights.

107. Energy and throughput trade-offs in cellular networks using base station switching

Author

Kumar, Abhinav, Rosenberg, C, Kumar, Abhinav, and Rosenberg, C

Abstract

Base station operation consumes a lot of energy, a considerable amount of which can be saved by switching off base stations during low user demand (for example, at night). Base station switching (BSS) can result in loss in coverage if not performed properly. We show that coverage is closely related to scheduling via power management and that the bottleneck is typically the uplink. To save energy, we propose a set of BSS patterns, at a global system-level, that have the potential to provide full coverage if the appropriate schedulers are used. We further show that the existing benchmark uplink scheduling schemes do not provide full coverage when BSS is used in urban as well as rural macro-cell environments (the downlink benchmark scheduling scheme provides full coverage only for some of the BSS patterns). Hence, we propose novel scheduling schemes for both uplink and downlink that realistically model interference, ensure full coverage, and provide good energy-performance trade-offs for the proposed BSS patterns. We also present a low complexity high performance heuristic for the proposed uplink scheduler. Finally, we show the presented models and results can be used to quantify, offline, the energy-performance trade-offs under different operating scenarios.

Abstract

This article focuses on the cyber defense technology networking and evaluation. To make rapid advances in defending against attacks, the state of the art in evaluation of network security mechanisms must be improved. Current deficiencies and impediments to evaluating network security mechanisms include lack of scientific rigor, lack of relevant and representative network data, inadequate models of defense mechanisms and inadequate models of the network and both the background and attack traffic data. To develop a testbed framework for evaluating security mechanisms, the project focuses on a select subset of the overall problem space. The framework will include attack scenarios, attack simulators, generators for topology and background traffic, data sets derived from live traffic and tools to monitor and summarize test results. The development of testing methodologies complemented by an experimental infrastructure will support the realistic and consistent evaluation of mechanisms purported to mitigate large-scale attacks.

Abstract

Microstructures of the Murray granite pluton (central Ontario, Canada) show evidence of both static and dynamic crystallization subsequent to partial melting. Backscattered electron analyses reveal interstitial K-feldspar and plagioclase at triple junctions of strain-free, isometric quartz grains. The geometry of the quartz-feldspar boundaries mimics the original topology of the quartz-melt contacts during crystallization. This conclusion is suggested by the occurrence of both rounded and planar faces of quartz grains, and by low (27 [degrees]) dihedral angles of quartz-quartz-feldspar boundaries, similar to dihedral angles in experimentally crystallized quartz-quartz-silicic melt systems. In contrast, feldspar seams in deformed granites have high axial ratios, are usually elongated perpendicular to the foliation plane, and are located preferentially along individual grain boundaries. Quartz grains are dynamically recrystallized and occasionally transected by feldspar seams, indicating that fracturing occurred in the presence of melt during crystal-plastic deformation of quartz. The subparallel orientation in quartz grains of intragranular, feldspar-bearing fractures and interstitial feldspar seams suggests that these features originated as intragranular and intergranular fractures, respectively. Partial-melt topology was therefore controlled by intergranular and, occasionally, by intragranular fracturing. Keywords: granite, microstructure, partial melting, melt topology, synmagmatic deformation.

Abstract

Item does not contain fulltext, PURPOSE: Submicroscopic deletions of chromosome band 2p25.3 are associated with intellectual disability and/or central obesity. Although MYT1L is believed to be a critical gene responsible for intellectual disability, so far no unequivocal data have confirmed this hypothesis. METHODS: In this study we evaluated a cohort of 22 patients (15 sporadic patients and two families) with a 2p25.3 aberration to further refine the clinical phenotype and to delineate the role of MYT1L in intellectual disability and obesity. In addition, myt1l spatiotemporal expression in zebrafish embryos was analyzed by quantitative polymerase chain reaction and whole-mount in situ hybridization. RESULTS: Complete MYT1L deletion, intragenic deletion, or duplication was observed in all sporadic patients, in addition to two patients with a de novo point mutation in MYT1L. The familial cases comprise a 6-Mb deletion in a father and his three children and a 5' MYT1L overlapping duplication in a father and his two children. Expression analysis in zebrafish embryos shows specific myt1l expression in the developing brain. CONCLUSION: Our data strongly strengthen the hypothesis that MYT1L is the causal gene for the observed syndromal intellectual disability. Moreover, because 17 patients present with obesity/overweight, haploinsufficiency of MYT1L might predispose to weight problems with childhood onset.Genet Med 17 6, 460-466.

Abstract

Cytogenetically, testicular germ cell tumors of adolescents and adults (TGCTs) are characterized by gain of 12p-sequences, most often through isochromosome formation (i(12p)), Fluorescence in situ hybridization (FISH) has shown that i(12p))-negative TGCTs also cryptically contain extra 12p-sequences. The consistency of 12p-over-representation in all histological subtypes of TGCTs, including their preinvasive stage, suggests that gain of one or more genes on 12p is crucial in the development of this cancer. So far, studies aimed at the identification of the relevant gene(s) were based on the 'candidate-gene approach'. No convincing evidence in favor of or against a particular gene has been reported. We combined conventional karyotyping, comparative genomic hybridization, and FISH to identify TGCTs with amplifications of restricted regions of 12p, Out of 49 primary TGCTs (23 without i(12p), 13 with and 13 unknown), eight tumors (six without i(12p) and two unknown) showed amplifications corresponding to 12p11.1-p12.1. Using bicolour-FISH, physical mapping, and semi-quantitative polymerase chain reactions, the size of the shortest region of overlap of amplification (SROA) was estimated to be between 1750-3000 kb, In addition, we mapped a number of genes in and around this region. While fourteen known genes could be excluded as candidates based on their location outside this region, we demonstrate that KRAS2, JAW1 and SOX5 genes are localized within the SROA, While KRAS2 and JAW1 map to the proximal border of the SROA, SOX5 maps centrally in the SROA, KRAS2 and JAW1 are expressed in all TGCTs, whereas one 12p amplicon-positive TGCT lacks expression of SOX5, The critical region of 12p over-represented in TGCTs is less than 8% of the total length of the short arm of chromosome 12, It will be helpful in the identification of the gene(s) involved in TGCT-development.

Abstract

The relation between reported chronic pain and clinical findings was studied by comparing survey data six months before and eighteen months after a clinical examination. Studied individuals (n = 165) were randomly selected from subsamples of an initial survey (n = 1806) to a general population. Among individuals reporting chronic pain 85% were assessed to have chronic pain at the examination. Diagnoses were found in 22% of examined pain individuals. Myofascial pain syndrome and myalgia were the most common findings. Compared with located neck-shoulder pain, widespread pain had a greater impact on the individual, a worse prognosis regarding pain duration and working capacity, and revealed a raised serum urate level of unclear significance. Although no specific cause of pain is found in individuals with widespread pain it is important to identify and treat this group due to the great effects on functional capacity and the worse prognosis.

2q24 deletion Seizures Mental impairment severe myoclonic epilepsy patient infancy disruption deletion parents slc4a10 scn1a
Abstract

P>Approximately 50% of all carriers of 2q21-q31 deletions present epileptic seizures. The band 2q24 constitutes the smallest commonly deleted segment in these patients, and contains the voltage-gated sodium channel genes SCN1A and SCN2A, associated with Dravet syndrome and benign familial neonatal-infantile seizures, respectively. A further putative locus involving epilepsy in the region was previously identified through disruption of the SLC4A10 gene by translocation. In the course of performing high-resolution DNA copy number analyses on syndromic mentally impaired individuals, we encountered three patients with overlapping deletions in chromosome region 2q24. Two of these patients exhibited epileptic seizures in addition to mental deficiency. The deletion in one of the epileptic patients did not include the SCN cluster, demonstrating that a less severe form of epilepsy maps to an adjacent genomic region. This second region comprises about 3 Mb and contains the candidate gene SLC4A10, providing further support for the potential role of this gene in epilepsy.
