Resource management in IP-based radio access networks

IP is being considered to be used in the Radio Access Network (RAN) of UMTS. It is of paramount importance to be able to provide good QoS guarantees to real time services in such an IP-based RAN. QoS in IP networks is most efficiently provided with Differentiated services (Diffserv). However, currently Diffserv mainly specifies Per Hop Behaviors (PHB). Proper mechanisms for admission control and resource reservation have not yet been defined. A new resource management concept in the IP-based RAN is needed to offer QoS guarantees to real time services. We investigate the current Diffserv mechanisms and contribute to development of a new resource management protocol. We focus on the load control algorithm [9], which is an attempt to solve the problem of admission control and resource reservation in IP-based networks. In this document we present some load control issues and propose to enhance the load control protocol with the Measurement Based Admission Control (MBAC) concept. With this enhancement the traffic load in the IP-based RAN can be estimated, since the ingress router in the network path can be notified by marking packets with the resource state information. With this knowledge, the ingress router can perform admission control to keep the IP-based RAN stable with a high utilization even in overload situations.
Surveillance for Malaria Elimination in Swaziland: A National Cross-Sectional Study Using Pooled PCR and Serology

Background To guide malaria elimination efforts in Swaziland and other countries, accurate assessments of transmission are critical. Pooled-PCR has potential to efficiently improve sensitivity to detect infections; serology may clarify temporal and spatial trends in exposure. Methodology/Principal Findings Using a stratified two-stage cluster, cross-sectional design, subjects were recruited from the malaria endemic region of Swaziland. Blood was collected for rapid diagnostic testing (RDT), pooled PCR, and ELISA detecting antibodies to Plasmodium falciparum surface antigens. Of 4330 participants tested, three were RDT-positive yet false positives by PCR. Pooled PCR led to the identification of one P. falciparum and one P. malariae infection among RDT-negative participants. The P. falciparum-infected participant reported recent travel to Mozambique. Compared to performing individual testing on thousands of samples, PCR pooling reduced labor and consumable costs by 95.5%. Seropositivity was associated with age ≥20 years (11·7% vs 1·9%, P<0.001), recent travel to Mozambique (OR 4.4 [95% CI 1.0–19.0]) and residence in southeast Swaziland (RR 3.78, P<0.001). Conclusions The prevalence of malaria infection and recent exposure in Swaziland are extremely low, suggesting elimination is feasible. Future efforts should address imported malaria and target remaining foci of transmission. Pooled PCR and ELISA are valuable surveillance tools for guiding elimination efforts.
A gain scheduled controller for sinusoidal ripple elimination of AC PM motor systems

An adaptive control algorithm for the elimination of torque and velocity ripples in the alternating current (AC) permanent magnet (PM) motor control systems is presented in this paper. A model of AC PM motor system includes n sinusoidal disturbances is first developed. The internal model principle (IMP) is then applied to design a controller to eliminate the torque and velocity ripples without estimating the amplitude and the phase values of the sinusoidal disturbances. Based on the IMP and the pole-zero placement technique, a gain scheduled (GS) robust two-degree-of-freedom (2DOF) speed regulator is developed to eliminate the torque and velocity ripples and to achieve a desirable tracking response. Using the small gain theorem, the system stability radius is obtained for n sinusoidal disturbances with slowly time-varying frequencies. The effectiveness of the proposed GS robust 2DOF speed regulator can be shown by the simulation results of an example with two sinusoidal disturbances.
Integration of SiP-Based 60-GHz 4 $\,\times\,$4 Antenna Array With CMOS OOK Transmitter and LNA

An integrated system-in-package-based 60-GHz 4 × 4 antenna array with CMOS on-off keying (OOK) transmitter and low-noise amplifier (LNA) is investigated. The 4 × 4 circular polarized array exhibits a wide impedance bandwidth (VSWR <; 2) and 3-dB axial ratio bandwidth of over 8 GHz using a strip line sequential rotation feeding scheme. It has a beam-shaped pattern with a 3-dB beamwidth of 20° and a peak gain of 16.8 dBi. The modulators in 90-nm CMOS includes 60-GHz oscillators and switchable amplifiers to achieve the OOK modulation. The key features of the circuits are small power consumption and size. By applying a bond wire compensation scheme, the LNA and 60-GHz CMOS modulator are successfully integrated into the low-temperature co-fired ceramic package with 2-mil 500-μm-long bond wires. The measurement results for the antenna array with LNA shows a peak gain of ~ 35 dBi. The 60-GHz CMOS modulator is tested at a data rate of 2 Gb/s and the bit-error performance of the system is also demonstrated. The energy usage of 60-GHz modulator at 2 Gb/s is only 13.2 pj/bit for the modulator.
An adaptive matching pursuit algorithm for linear frequency modulation signal compressive sampling

We focus on the problem of compressive sampling of Linear Frequency Modulation(LFM) signal via Matching Pursuit. We designed an adaptive matching pursuit algorithm through dynamic dictionary optimization. Results from the sparse property of LFM under Chirplet Basis, we use Chirplet atom to generate dictionary. Then by feeding the information of signal back into dictionary generating process, the grid error can be reduced significantly. It also allows us to get better parameter estimation results and lower signal sampling rate. We demonstrate computing performance on a LFM signal sampling example.
Fate of Mammalian Cochlear Hair Cells and Stereocilia after Loss of the Stereocilia

Cochlear hair cells transduce mechanical stimuli into electrical activity. The site of hair cell transduction is the hair bundle, an array of stereocilia with different height arranged in a staircase. Tip links connect the apex of each stereocilium to the side of its taller neighbor. The hair bundle and tip links of hair cells are susceptible to acoustic trauma and ototoxic drugs. It has been shown that hair cells in lower vertebrates and in the mammalian vestibular system may survive bundle loss and undergo self-repair of the stereocilia. Our goals were to determine whether cochlear hair cells could survive the trauma and whether the tip link and/or the hair bundle could be regenerated. We simulated the acoustic trauma-induced tip link damage or stereociliary loss by disrupting tip links or ablating the hair bundles in the cultured organ of Corti from neonatal gerbils. Hair-cell fate and stereociliary morphology and function were examined using confocal and scanning electron microscopies and electrophysiology. Most bundleless hair cells survived and developed for ∼2 weeks. However, no spontaneous hair-bundle regeneration was observed. When tip links were ruptured, repair of tip links and restoration of mechanotransduction were observed in <24 h. Our study suggests that the dynamic nature of the hair cell's transduction apparatus is retained despite the fact that regeneration of the hair bundle is lost in mammalian cochlear hair cells.
The Prevalence and Awareness of Cardiometabolic Risk Factors in Southern Chinese Population with Coronary Artery Disease

Background. Cardiometabolic risk factors significantly accelerate the progression of coronary artery disease (CAD); however, whether CAD patients in South China are aware of the prevalence of these risk factors is not clear yet. Methods. The study consisted of 2312 in-admission CAD patients from 2008 to 2011 in South China. Disease history including hypertension, dyslipidemia, and diabetes was relied on patients' self-reported records. Physical and clinical examinations were tested to assess the real prevalence of the cardiometabolic risk factors. Results. 57.9% of CAD patients had more than 3 cardiometabolic risk factors in terms of the metabolic syndrome. The self-known and real prevalence of hypertension, diabetes, and dyslipidemia were 56.6%, 28.3%, and 25.1% and 91.3%, 40.9%, and 92.0%, respectively. The awareness rates were 64.4%, 66.3%, and 28.5% for hypertension, diabetes, and dyslipidemia. The prevalence of cardiometabolic risk factors was significantly different among gender and among disease status. Conclusions. Most CAD patients in South China had more than three cardiometabolic risk factors. However, the awareness rate of cardiometabolic diseases was low, especially for dyslipidemia. Strategies of routine physical examination programs are needed for the early detection and treatment of cardiometabolic risk factors in order to prevent CAD progression and prognosis.
The Dynamic Deprivation Index: measuring relative socio-economic deprivation in NZ on a monthly basis

ABSTRACT The standard measures of relative socio-economic deprivation within New Zealand are the NZDEP studies and the NZ IMD. Although both sets of studies are extremely rigorous, high quality research outputs they are only able to provide a snapshot of the national distribution of relative socio-economic deprivation at fixed points in time. The inability to express deprivation levels as an extended and current time series means that not only are policy analysts and researchers working with outdated information, but also that it is often unfeasible to associate changes in deprivation levels to specific events or policy implementations. The Dynamic Deprivation Index (DDI) assigns a deprivation score and deprivation index to each area unit in New Zealand on a monthly basis. In this paper we look to describe the methodology behind the construction of the DDI and to validate the results therein. We argue that if public bodies were to make the data they hold more easily accessible, then there is no reason why New Zealand should not be able to benefit from a measure of socio-economic deprivation that combines the sophistication of the NZDEP studies or IMD with the contemporaneousness of the DDI.
Information accessibility and cryptic processes

We give a systematic expansion of the crypticity—a recently introduced measure of the inaccessibility of a stationary process's internal state information. This leads to a hierarchy of k-cryptic processes and allows us to identify finite-state processes that have infinite cryptic order—the internal state information is present across arbitrarily long, observed sequences. The crypticity expansion is exact in both the finite- and infinite-order cases. It turns out that k-crypticity is complementary to the Markovian finite-order property that describes state information in processes. One application of these results is an efficient expansion of the excess entropy—the mutual information between a process's infinite past and infinite future—that is finite and exact for finite-order cryptic processes.
An introduction to contemporary egalitarianism

During the 1980s, the number of homeless people in the United States grew rapidly. This was due, among other things, to the Reagan administration’s severe cuts to the housing budget. In fact, by the end of the Reagan years the federal government was spending $8 billion annually on housing. The Carter administration had spent $32 billion annually at a time when homelessness was far less common (Singer 1993: 28). 1 Most egalitarians would think that Reagan’s cuts were unjust. This is because these cuts increased inequality. However, egalitarians would not be alone in objecting to Reagan’s cuts on the grounds of justice. Most utilitarians would also be troubled, because they would think that the harm the homeless suffered was substantial and not counterbalanced by benefits to taxpayers. These utilitarians would conclude that the Reagan administration produced less total welfare than it could have done with a more generous housing budget and so acted wrongly. The egalitarian explanation of why Reagan’s cuts were unjust refers to equality whereas the utilitarian explanation does not. There is nevertheless a sense in which both egalitarians and utilitarians attach value to equality. In fact, all major normative political theories subscribe to equality in this wide sense. They share what Thomas
Retinopathy in diabetes.

Diabetic retinopathy is the most frequent cause of new cases of blindness among adults aged 20 –74 years. During the first two decades of disease, nearly all patients with type 1 diabetes and 60% of patients with type 2 diabetes have retinopathy. In the Wisconsin Epidemiologic Study of Diabetic Retinopathy (WESDR), 3.6% of younger-onset patients (type 1 diabetes) and 1.6% of olderonset patients (type 2 diabetes) were legally blind. In the younger-onset group, 86% of blindness was attributable to diabetic retinopathy. In the older-onset group, in which other eye diseases were common, one-third of the cases of legal blindness were due to diabetic retinopathy. NATURAL HISTORY OF DIABETIC RETINOPATHY Diabetic retinopathy progresses from mild nonproliferative abnormalities, characterized by increased vascular permeability, to moderate and severe nonproliferative d iabetic r etinopathy (NPDR), characterized by vascular closure, to proliferative diabetic retinopathy (PDR), characterized by the growth of new blood vessels on the retina and posterior surface of the vitreous. Macular edema, characterized by retinal thickening from leaky blood vessels, can develop at all stages of retinopathy. Pregnancy, puberty, blood glucose control, hypertension, and cataract surgery can accelerate these changes. Vision-threatening retinopathy is rare in type 1 diabetic patients in the first 3–5 years of diabetes or before puberty. During the next two decades, nearly all type 1 diabetic patients develop retinopathy. Up to 21% of patients with type 2 diabetes have retinopathy at the time of first diagnosis of diabetes, and most develop some degree of retinopathy over time. Vision loss due to diabetic retinopathy results from several mechanisms. Central vision may be impaired by macular edema or capillary nonperfusion. New blood vessels of PDR and contraction of the accompanying fibrous tissue can distort the retina and lead to tractional retinal detachment, producing severe and often irreversible vision loss. In addition, the new blood vessels may bleed, adding the further complication of preretinal or vitreous hemorrhage. Finally, neovascular glaucoma associated with PDR can be a cause of visual loss.

Homelessness and Child Welfare Services in New York City: Exploring Trends and Opportunites for Improving Outcomes for Children and Youth

For over a decade, national research has shown that many disadvantaged youth and families experience both homelessness and involvement in child welfare services. However, prior to the research summarized here, no population-based research had examined systematically the extent and dynamics by which children and youth experience both of these service systems. This white paper for the New York City Administration for Children's Services (ACS) provides a summary of three studies that looked carefully at how these two important social welfare systems have shared a population, and how our improved understanding of these intersecting systems of care can promote better outcomes and improved quality of life for children and youth.
A distance spectrum interpretation of turbo codes

The performance of turbo codes is addressed by examining the code's distance spectrum. The "error floor" that occurs at moderate signal-to-noise ratios is shown to be a consequence of the relatively low free distance of the code. It is also shown that the "error floor" can be lowered by increasing the size of the interleaver without changing the free distance of the code. Alternatively, the free distance of the code may be increased by using primitive feedback polynomials. The excellent performance of turbo codes at low signal-to-noise ratios is explained in terms of the distance spectrum. The interleaver in the turbo encoder is shown to reduce the number of low-weight codewords through a process called "spectral thinning. " This thinned distance spectrum results in the free distance asymptote being the dominant performance parameter for low and moderate signal-to-noise ratios.
Enhanced Effect of Human Cardiac Stem Cells and Bone Marrow Mesenchymal Stem Cells to Reduce Infarct Size and Restore Cardiac Function after Myocardial Infarction

: Background —As mesenchymal stem cells (MSCs) induce proliferation and differentiation of c-kit+ cardiac stem cells (CSCs) in vivo and in vitro, we hypothesized that combining human (h)MSCs with c-kit+ hCSCs produces greater infarct size reduction compared to either cell administered alone after MI. Methods and Results —Yorkshire swine underwent balloon occlusion of the LAD coronary artery followed by reperfusion, and were immunosuppressed after MI with cyclosporine and methylprednisolone. Intramyocardial injection of either: combination hCSCs/hMSCs (1M/200M, n=5), hCSCs alone (1M, n=5), hMSCs alone (200M, n=5), or placebo (PBS, n=5) was administered to the infarct border zones at 14 days post-MI. Phenotypic response to cell therapy was assessed by cardiac MRI and micromanometer conductance catheterization hemodynamics. While each cell therapy group had reduced MI size relative to placebo (p<0.05), the MI size reduction was 2-fold greater in combination vs. either cell therapy alone (p<0.05). Accompanying enhanced MI size reduction was substantial improvement in LV chamber compliance (end-diastolic pressure volume relationship, p<0.01) and contractility (preload recruitable stroke work and dP/dt max , p<0.05) in combination treated swine. EF was restored to baseline in cell treated pigs, while placebo pigs had persistently depressed LV function (p<0.05). Immunohistochemistry showed 7-fold enhanced engraftment of stem cells in the combination therapy group vs. either cell type alone (P<0.001). Conclusions —Combining hMSCs and hCSCs as a cell therapeutic enhances scar size reduction, and restores diastolic and systolic function toward normal after MI. Taken together these findings illustrate important biological interactions between c-kit+ CSCs and MSCs that enhance cell-based therapeutic responses.

Members of the RAD52 Epistasis Group Contribute to Mitochondrial Homologous Recombination and Double-Strand Break Repair in Saccharomyces cerevisiae

Mitochondria contain an independently maintained genome that encodes several proteins required for cellular respiration. Deletions in the mitochondrial genome have been identified that cause several maternally inherited diseases and are associated with certain cancers and neurological disorders. The majority of these deletions in human cells are flanked by short, repetitive sequences, suggesting that these deletions may result from recombination events. Our current understanding of the maintenance and repair of mtDNA is quite limited compared to our understanding of similar events in the nucleus. Many nuclear DNA repair proteins are now known to also localize to mitochondria, but their function and the mechanism of their action remain largely unknown. This study investigated the contribution of the nuclear double-strand break repair (DSBR) proteins Rad51p, Rad52p and Rad59p in mtDNA repair. We have determined that both Rad51p and Rad59p are localized to the matrix of the mitochondria and that Rad51p binds directly to mitochondrial DNA. In addition, a mitochondrially-targeted restriction endonuclease (mtLS-KpnI) was used to produce a unique double-strand break (DSB) in the mitochondrial genome, which allowed direct analysis of DSB repair in vivo in Saccharomyces cerevisiae. We find that loss of these three proteins significantly decreases the rate of spontaneous deletion events and the loss of Rad51p and Rad59p impairs the repair of induced mtDNA DSBs.
Commercial Vehicles in Delhi: Diesel Demand and Sulphur Emission

The aim of this paper is to estimate the future growth of commercial vehicles (passenger vehicles and goods vehicles) and to project the subsequent increase in diesel demand and the level of sulphur dioxide emissions in Delhi. Using an S-curve growth model on the data set of auto rickshaws, taxis, buses, and goods vehicles from 1965- 66 to 2005-06, a long-term trend in the growth of commercial vehicles is projected to the year 2020-21. By 2020-21, the number of commercial vehicles is expected to increase to 0.51 million, with an increase in the share of goods vehicles and a simultaneous decrease in the share of passenger vehicles. The growth of commercial vehicles will boost the demand for diesel in 2020-21 by 68 percent, thus resulting in a threefold increase in sulphur dioxide emissions. The conversion of goods vehicle engines from diesel to CNG (compressed natural gas) will reduce diesel demand and sulphur dioxide levels significantly. A reduction of sulphur content in diesel can further reduce sulphur dioxide emissions.
Semi-Automated Integration of Legacy Systems Using Linked Data

A lot of valuable data is stored in standalone legacy systems inside enterprise infrastructure across different domains. It was always a big challenge to integrate such systems with each other even on structural level, but with the recent development of Semantic Web technologies its now clear that integration on semantic level could be achieved and data from different sources could be used more effectively. Its now becoming a trend to open data to the public according to Linked Data principals, but there is no common workflow that could be used with legacy systems. In this paper we propose our solution for semi-automated integration of legacy systems using Linked data principals. We analyze the motivation and current state of the art in the domain, present our method and algorithms for data extraction, transformation, mapping and interlinking. Finally we show our own implementation of the proposed solution and discuss the results.
