Abstract:
Abstract We construct a conformal field theory dual to string theory on AdS3 with pure NS–NS flux. It is given by a symmetric orbifold of a linear dilaton theory deformed by a marginal operator from the twist-2 sector. We compute two- and three-point functions on the CFT side to 4th order in conformal perturbation theory at large N. They agree with the string computation at genus 0, thus providing ample evidence for a duality. We also show that the full spectra of both short and long strings on the CFT and the string side match. The duality should be understood as perturbative in N −1.

Abstract:
En el mundo tecnológico actual, donde las redes están creciendo rápidamente, se exige que los protocolos de red sean robustos, confiables y versátiles. Es por ello que antes de ser propuestos para su uso, deben ser estudiados a fondo, para lo que se requiere utilizar herramientas informáticas que permitan examinar su comportamiento en diferentes entornos. Es así que, con este fin, se utilizan simuladores de redes. Uno de estos simuladores es el ns-2, que ha sido utilizado de manera exhaustiva en ámbitos académicos y científicos por casi dos décadas. Sin embargo, con el lanzamiento de un nuevo simulador, el ns-3, que difiere en muchos aspectos de su antecesor y requiere la reformulación de los programas escritos para la versión anterior, surge el interrogante si la actualización a las nuevas versiones es realmente necesaria. Es así que, nos preguntamos si el simulador de redes que utilizamos es suficiente para nuestro trabajo o si la nueva versión aportará considerables beneficios en las investigaciones actuales y futuras. Determinar si la inversión de tiempo en el aprendizaje de una nueva herramienta, producirá suficientes mejorías en las tareas que requiere la investigación de redes, es una decisión importante. Este informe presenta de manera comparativa las dos versiones del simulador. Se describen las ventajas y desventajas, alcances, limitaciones y requisitos para la utilización de cada una de las versiones.

Abstract:
Abstract We evaluated four different health related quality of life measures to determine their ability to detect change over time. The four measures included the Health Utilities Index Mark 2 and 3 (HUI 2/3), the PedsQLTM 4.0 Generic Core and Cancer Module, the EuroQol and the Lansky Play - Performance Scale. Children with Hodgkin’s disease, their parents and the clinic nurse were all asked to complete the four measures at four time points: 2 weeks after the 1st course of chemotherapy, on the 3rd day of the 2nd course of chemotherapy, during the 3rd week of radiation and 1 year after diagnosis. At each follow up time point the respondents were asked to indicate whether the child’s HRQL had improved, stayed the same or became worse since the last measurement. 51 adolescents from 12 centres across Canada were enrolled in the study between May 1, 2002 and March 31, 2005. Two patients were excluded: one patient died shortly after the first time point, and the other patient failed to complete any of the questionnaires. The 49 patients included in the analysis had an average age of 14.7 years (8.9 - 17.9), with the two most common stages being IIA (39%) and IVA (18%). Complete data was available on 92% of patients at time 2, 89% at time 3 and 76% at time 4. Four of the 36 patients with complete follow up had relapsed (11%). The summary scores from the patients responses can be seen in the graph below. Figure Figure All measures showed a significant change between time 1 and time 4 (<0.05). When the change in child scores was analysed between the time points using the child’s self-reported change in HRQL, the PedsQL and the EuroQol showed significant change at all time points.

Abstract:
Network simulator (ns-3) is a reputed simulation platform for performance evaluation of cellular networks. In this work, we explore the use of ns-3 for tracking of successful handovers (HO) and handover failures and consequent impact on 4G LTE network throughput with the aim of discovering new analytical relations about HOs and new methods to optimize the resulting throughput. Decreased cell sizes in newer generation networks lead to increasing number of handovers and handover failures that have significant impact. We begin by reviewing analytical models in the literature that aim to predict number of HO and HO failures in terms of HO control and network parameters. We initially conduct a suite of exhaustive validation studies of such analytical models, based on the simulation execution manager (SEM) for ns-3 for parallelization. Via this, we discover new causal relations relating HO failures and choice of HO control parameters on network throughput. Based on these initial results, we next evaluate the application of Gaussian process regression for prediction of instantaneous network throughput and bandit algorithms as an effective mechanism to optimize throughput over time. The new relations discovered help better understand the impact of input handover control parameters on the number of handovers and handover failures allowing us to fine tune them. The new optimization and prediction methods discovered give good gains over baseline algorithms and help accurately predict throughput respectively.

Abstract:
ABSTRACT The genome of Junonia coenia densovirus (JcDNV) shares with members of the genus Densovirus the property of possessing structural (VP) and nonstructural (NS) genes in opposite orientations. The three NS genes located in the 5′ half on one strand encode three NS proteins assumed to be involved in viral DNA replication: NS-1 and NS-2, which are common to all DNVs, and a 28-kDa polypeptide, NS-3, with a unique sequence. Whereas the essential role played by JcDNV NS-1 in viral DNA replication has been clearly established (C. Ding, M. Urabe, M. Bergoin, and R. M. Kotin, J. Virol. 76:338-345, 2002), nothing is known of the biological function(s) of NS-3. To investigate this function, we designed constructs derived from pBRJ, a plasmid encompassing an infectious sequence of JcDNV DNA (M. Jourdan, F. X. Jousset, M. Gervais, S. Skory, M. Bergoin, and B. Dumas, Virology 179:403-409, 1990), with partial or complete deletion of NS-3 sequence or with the ATG initiation codon mutated by site-directed mutagenesis. Transfection of these constructs to sensitive Ld 652 cells or Spodoptera littoralis larvae prevented the accomplishment of a productive cycle. We clearly established that the blocking of the replicative cycle in the absence of NS-3 expression occurred at the level of viral DNA replication. Replication of viral DNA could be restored by cotransfecting Ld 652 cells with a plasmid expressing JcDNV-NS-3 protein in trans. Time course analysis showed that NS-3 is produced early (6 h posttransfection) in the replicative cycle, and its production parallels that of replicative-form viral DNA. Finally, we present evidence that NS-1 and NS-2 proteins are synthesized at apparently the same levels whether or not NS-3 is expressed.

Abstract:
Complexity of current computer networks, including e.g., local networks, large structured networks, wireless sensor networks, datacenter backbones, requires a thorough study to perform analysis and support design. Simulation is a tool of paramount importance to encompass all the different aspects that contribute to design quality and network performance (including as well energy issues, security management overheads, dependability), due to the fact that such complexity produces several interactions at all network layers that is not easily modellable with analytic approaches. In this systematic literature review we aim to analyze, basing our investigation on available literature, the adoption of a popular network simulator, namely ns-3, and its use in the scientific community. More in detail, we are interested in understanding what are the impacted application domains in which authors prefer ns-3 to other similar tools and how extensible it is in practice according to the experience of authors. The results of our analysis, which has been conducted by especially focusing on 128 papers published between 2009 to 2019, reveals that 10% of the evaluated papers were discarded because they represented informal literature; most of the studies presented comparisons among different network simulators, beyond ns-3 and conceptual studies related to performance assessment and validation and routing protocols. Only about 30% of considered studies present extensions of ns-3 in terms of new modules and only about 10% present effective case studies demonstrating the effectiveness of employing network simulator in real application, except conceptual and modeling studies.

Abstract:
NanoSheet-Gate-All-Around-FETs (NS-GAAFETs) are commonly recognized as the future technology to push the digital node scaling into the sub-3 nm range. NS-GAAFETs are expected to replace FinFETs in a few years, as they provide highly electrostatic gate control thanks to the GAA structure, with four sides of the NS channel entirely enveloped by the gate. At the same time, the NS rectangular cross-section is demonstrated to be effective in its driving strength thanks to its high saturation current, tunable through the NS width used as a design parameter. In this work, we develop a NS-GAAFET compact model and we use it to link peculiar single-device parameters to digital circuit performance. In particular, we use the well-known BSIM-CMG core solver for multigate transistors as a starting point and develop an ad hoc resistive and capacitive network to model the NS-GAAFET geometrical and physical structure. Then, we employ the developed model to design and optimize a digital inverter and a five-stage ring oscillator, which we use as a performance benchmark for the NS-GAAFET technology. Through Cadence Virtuoso SPICE simulations, we investigate the digital NS-GAAFET performance for both high-performance and low-power nodes, according to the average future node present in the International Roadmap for Devices and Systems. We focus our analysis on the main different technological parameters with regard to FinFET, i.e., the inner and outer spacers. Our results highlight that in future technological nodes, the choice of alternative low-K dielectric materials for the NS spacers will assume increasing importance, being as relevant, or even more relevant, than photolithographic alignment and resolution at the sub-nm scale.

Abstract:
This study sought to compare the in vitro characteristics of fresh and frozen non-sorted (NS) and sex-sorted (SS) bull spermatozoa. Experiment 1: Holstein–Friesian ejaculates (n = 10 bulls) were split across four treatments and processed: (1) NS fresh at 3 × 106 spermatozoa, (2) X-SS frozen at 2 × 106 spermatozoa, (3) X-SS fresh at 2 × 106 spermatozoa and (4) X-SS fresh at 1 × 106 spermatozoa. NS frozen controls of 20 × 106 spermatozoa per straw were sourced from previously frozen ejaculates (n = 3 bulls). Experiment 2: Aberdeen Angus ejaculates (n = 4 bulls) were split across four treatments and processed as: (1) NS fresh 3 × 106 spermatozoa, (2) Y-SS fresh at 1 × 106 spermatozoa, (3) Y-SS fresh at 2 × 106 spermatozoa and (4) X-SS fresh at 2 × 106 spermatozoa. Controls were sourced as per Experiment 1. In vitro assessments for progressive linear motility, acrosomal status and oxidative stress were carried out on Days 1, 2 and 3 after sorting (Day 0 = day of sorting. In both experiments SS fresh treatments had higher levels of agglutination in comparison to the NS fresh (P < 0.001), NS frozen treatments had the greatest PLM (P < 0.05) and NS spermatozoa exhibited higher levels of superoxide anion production compared with SS spermatozoa (P < 0.05). Experiment 1 found both fresh and frozen SS treatments had higher levels of viable acrosome-intact spermatozoa compared with the NS frozen treatments (P < 0.01).

Abstract:
Precise Point Positioning (PPP) is an official service of the BeiDou Global Navigation Satellite System (BDS-3) through the PPP-B2b signal. In this paper, we mainly focus on the long-term performance evaluation of BDS-3 PPP-B2b products and their application in time service. Since the PPP-B2b product is only available in and around China area, the arcs of PPP-B2b products are about several hours. We propose to evaluate the time datum stability by using all available satellites. Then, 557 day PPP-B2b products are collected for this experiment. The results show that there are large jumps in the GPS satellite clock time datum series. However, the BDS-3 satellite clock datum stability is almost at the same level with current Space State Representation (SSR) corrections from the International Global navigation satellite system Service (IGS). The difference between PPP-B2b GPS and BDS-3 satellite clock time datum will be absorbed into the Inter System Bias (ISB) parameter. Thus, it should be specially noted that the ISB parameter cannot be estimated as constant values if users use PPP-B2b products. In addition, the accuracy of the BDS-3 satellite clock is significantly better than that of the GPS for both the Root Mean Square Error (RMSE) and standard deviation (STD). The average Signal in Space Range Errors (SISREs) is 0.22 ns and 0.13 ns for GPS and BDS-3, respectively. The one-way timing experiment shows BDS-3 timing stability is 2.9 × 10−14@104 s. In addition, 10 baselines from 13 km to 4494 km are formed for time synchronization evaluation by using PPP-B2b products. The average RMSEs of time synchronization is from 0.46 ns to 1.58 ns and from 0.66 ns to 1.19 ns for GPS and BDS-3, respectively. As for STD, the average values are from 0.27 ns to 0.74 ns and from 0.27 ns to 0.47 ns for GPS and BDS-3, respectively. Overall, the results show that the time datum stability, accuracy, and service performance of BDS-3 PPP-B2b products has been stable over the past two years.

Abstract:
Introduction: Acute necrotizing pancreatitis with a high mortality rate and the search for treatment continues. We investigated the protective effect of Nigella Sativa (NS), with antioxidant and anti-inflammatory effects, in experimental acute necrotizing pancreatitis. Materials and Methods: Thirty six male Wistar albino rats (weights 180-220 g) were randomised into four groups. Group 1 (Control): Rats were given standard mouse chow. No pro-drug or pancreatic intervention was performed. Group 2 (NS): In addition to their standard diet, rats were given 0.1 ml/100gr of NS orally for 3 days prior to the experiment. Group 3: Necrotizing pancreatitis was induced by retrograde administration of 3% Na-Taurocholate through the distal common bile duct of the rats on on experiment day. Group 4 (NS+ANP): Necrotizing pancreatitis was also formed in rats receiving 0.1ml/100 mg of NS for 3 days. Rats were given high-dose anesthesia 8 hours after the onset of pancreatitis. Immunohistochemical (TNF-a, MDA, MPO, Caspase), histological pancreatitis scoring and biochemical (LDH, Lipase, amylase) analyzes were performed from the blood and pancreatic tissue samples obtained. Results: There was no difference in histopathological, immunohistochemical and biochemical values between Group 1 and Group 2 (p>0.05). There were significiant differences between Group 4 and Group 3 in terms of histopathological, immunohistochemical and biochemical parameters (p<0.001). The pancreatitis findings of the Group 4 were found to be significantly milder than Group 3, which did not receive NS. Conclusion: NS pretreatment alleviates NaTaurocholate-induced experimental pancreatitis. NS firstly studied in experimental models of pancreatitis.

Abstract:
The multipath transmission control protocol (MPTCP) is considered a promising wireless multihoming solution, and the 3rd generation partnership project (3GPP) includes it as a standard feature in the fifth-generation (5G) networks. Currently, ns-3 (Network Simulator-3) is widely used to evaluate the performance of wireless networks and protocols, including the emerging MPTCP protocol. This paper investigates the fidelity of the Linux kernel implementation of MPTCP in the ns-3 direct code execution module. The fidelity of MPTCP simulation is tested by comparing its performance with a real Linux stack implementation of MPTCP using a hardware testbed for two different setups. One setup emulates the existence of a bottleneck link between the sending and receiving networks, whereas the other setup does not have such a bottleneck. The fidelity of ns-3’s simulation is tested for four congestion control algorithms, namely Cubic, linked-increases algorithm (LIA), opportunistic LIA (OLIA) and wVegas for relatively short and long data flows. It is found that the uplink MPTCP throughput performance exhibited by the ns-3 simulator matches the hardware testbed results only if the flows are long-lived and share no common bottleneck link. Likewise, the MPTCP throughput achieved during a downlink scenario using the ns-3 simulator and the hardware testbed are close to each other across all algorithms except wVegas regardless of the flow size if there is no bottleneck link. Moreover, it is observed that the impact of LTE handover on MPTCP throughput is less significant in the simulator than the real hardware testbed, and it is setup-dependent.

Abstract:
ObjectiveThe objective of this study was to determinate whether the introduction of nerve-sparing (NS) procedure influences surgical and survival outcomes of cervical cancer patients undergoing laparoscopic radical hysterectomy (LRH).MethodsData of consecutive patients undergoing minimally invasive radical with or without NS surgery for cervical cancer were enrolled in the study.ResultsSixty-three patients (66%) who had LRH were compared with 33 women (34%) undergoing NS-LRH. Among the NS group, 19 patients (57.6%) had surgery via minilaparoscopy (using 3-mm instruments). Baseline characteristics were similar between groups. Patients undergoing NS-LRH had shorter operative time (210 vs 257 minutes; P = 0.005) and higher number of pelvic lymph nodes yielded (29 [26–38] vs 22 [8–49]; P < 0.001) than patient in the control group. No differences in blood loss, complications, and parametrial width were observed. Patients were catheterized with an indwelling Foley catheter for a median of 3.5 days (2–7 days) and 5.5 days (4–7 days) in NS and non-NS groups, respectively (P = 0.01). Voiding dysfunctions occurred in 1 patient (3%) and 12 patients (19%) who underwent NS-LRH and standard LRH, respectively (P = 0.03). No differences in 3-year disease-free survival (P = 0.72) and overall survival (P = 0.71) were recorded.ConclusionsThe beneficial effects (in terms of operative time and number of nodes harvested) of NS-LRH are likely determined by the expertise of the surgeon because NS approach was introduced after having acquired adequate background in conventional LRH. Our data show that in experienced hands NS-LRH is safe and feasible. Moreover, NS technique reduces catheterization time and the rate of postoperative urinary dysfunction.

Abstract:
ABSTRACT Advanced LIGO and Advanced Virgo are detecting a large number of binary stellar origin black hole (BH) mergers. A promising channel for accelerated BH merger lies in active galactic nucleus (AGN) discs of gas around supermasssive BHs. Here, we investigate the relative number of compact object (CO) mergers in AGN disc models, including BH, neutron stars (NS), and white dwarfs, via Monte Carlo simulations. We find the number of all merger types in the bulk disc grows ∝ t1/3 which is driven by the Hill sphere of the more massive merger component. Median mass ratios of NS–BH mergers in AGN discs are $\tilde{q}=0.07\pm 0.06(0.14\pm 0.07)$ for mass functions (MF) M−1(− 2). If a fraction fAGN of the observed rate of BH–BH mergers (RBH–BH) come from AGN, the rate of NS–BH (NS–NS) mergers in the AGN channel is ${R}_{\mathrm{ BH}\!-\!\mathrm{ NS}} \sim f_{\mathrm{ AGN}}[10,300]\, \rm {Gpc}^{-3}\, \rm {yr}^{-1},({\mathit{ R}}_{NS\!-\!NS} \le \mathit{ f}_{AGN}400\, \rm {Gpc}^{-3}\, \rm {yr}^{-1}$). Given the ratio of NS–NS/BH–BH LIGO search volumes, from preliminary O3 results the AGN channel is not the dominant contribution to observed NS–NS mergers. The number of lower mass gap events expected is a strong function of the nuclear MF and mass segregation efficiency. CO merger ratios derived from LIGO can restrict models of MF, mass segregation, and populations embedded in AGN discs. The expected number of electromagnetic (EM) counterparts to NS–BH mergers in AGN discs at z &lt; 1 is $\sim [30,900]\, {\rm {yr}}^{-1}(f_{\mathrm{ AGN}}/0.1)$. EM searches for flaring events in large AGN surveys will complement LIGO constraints on AGN models and the embedded populations that must live in them.

Abstract:
During the last decade, the number of vehicles on roads has been rapidly growing. Therefore, the demands for communication on the move are also increasing and the attention from many researchers is focused on the Vehicular Ad hoc NETworks (VANETs) because of their importance for Intelligent Transportation Systems (ITSs). Due to the complexity and cost of practical evaluation of VANETs, the researchers often rely on network simulation in order to evaluate their work. In this paper, we have developed a Network Simulator 3 (NS-3) based framework for VANETs that provides network performance analysis based on the key performance indicators such as throughput, packet loss ratio, overhead, end-to-end delay, jitter, etc. Since VANETs are highly dynamic networks, many researchers have proposed different routing protocols in order to improve the network performance. In this paper we have compared several topology-based routing protocols, and proposed utilization of the commonly used Expected Transmission Count (ETX) metric to improve VANET performance.

Abstract:
La principal característica del servicio de video bajo demanda a través de la tecnología de video streaming es el consumo de grandes anchos de banda, por lo que los planificadores de redes deben considerar este servicio en el momento de dimensionar dichas redes. Para alcanzar esta meta, una de las herramientas es la ingeniería de tráfico y sus modelos asociados. Así, este artículo presenta un modelo de tráfico basado en la simulación por eventos discretos y desarrollado a través del software de código abierto y de investigación en redes, denominado ns-3. Se describen las abstracciones de los elementos de red, y el proceso de construcción de diferentes escenarios de evaluación, independiente de las características del servicio que se desee analizar, y la recolección y visualización gráfica de estadísticas. Finalmente se presentan los análisis de los parámetros de desempeño que permiten obtener las características mínimas de red para soportar el servicio.
