Analysis and Evaluation of End-to-End PTP Synchronization for Ethernet-Based Fronthaul

Provisioning of cost-effective Ethernet-based fronthaul by reusing the LAN infrastructure available in most commercial buildings is challenging predominantly in terms of the required bandwidth and synchronization. In contrast to a synchronous fronthaul, a PTP-based Ethernet network must cope with estimation noise introduced by packet delay variation (PDV) for synchronization recovery. The SYNC packet used for PTP on such networks is expected to suffer from significant PDV due to the fronthaul traffic and other background traffic. Further challenges are met when the switches adopted in the network do not support PTP and therefore synchronization can only be done by end-devices. Focusing on this scenario, this paper analyzes the problems that may affect the time offset estimation accuracy and presents schemes to mitigate these problems. The performance is evaluated through a self-developed FPGA-based testbed and the results suggest that the end-to-end PTP approach can fulfill the less strict time alignment requirements of 3GPP standards if PDV is handled properly.
Regularizing AdaBoost with validation sets of increasing size

AdaBoost is an iterative algorithm to construct classifier ensembles. It quickly achieves high accuracy by focusing on objects that are difficult to classify. Because of this, AdaBoost tends to overfit when subjected to noisy datasets. We observe that this can be partially prevented with the use of validation sets, taken from the same noisy training set. But using less than the full dataset for training hurts the performance of the final classifier ensemble. We introduce ValidBoost, a regularization of AdaBoost that takes validation sets from the dataset, increasing in size with each iteration. ValidBoost achieves performance similar to AdaBoost on noise-free datasets and improved performance on noisy datasets, as it performs similar at first, but does not start to overfit when AdaBoost does.

Apoptosis is a prominent feature of acute anterior uveitis in the Fischer 344 rat

AIMS To examine the hypothesis that apoptosis of infiltrating cells contributes to spontaneous resolution of uveitis in clinically relevant rodent models. METHODS Experimental melanin induced uveitis (EMIU) was induced in Fischer 344 rats by immunisation with 250 μg bovine ocular melanin. Endotoxin induced uveitis (EIU) was induced by injection of 200 μgEscherichia coli lipopolysaccharide. Formalin fixed, paraffin embedded ocular cross sections were stained by terminal deoxynucleotidyl transferase mediated deoxyuridine triphosphate biotin nick end labelling (TUNEL) to identify apoptotic cells. Indirect immunoperoxidase staining of paraformaldehyde lysine periodate fixed tissue cross sections was used to demonstrate expression of inducible nitric oxide synthase (iNOS). RESULTS TUNEL positive mononuclear cells were observed in the anterior uvea during both EMIU and EIU at all selected time points. However, whereas the majority of mononuclear cells appeared apoptotic from the outset of disease, neutrophils were notably TUNEL negative at all time points examined. Many infiltrating neutrophils expressed iNOS. CONCLUSION Apoptosis occurs early in the course of rat EMIU and EIU, and may contribute to resolution of these diseases. In general, infiltrating mononuclear cells die rapidly, while neutrophils survive, producing inducible nitric oxide synthase which may contribute to disease pathogenesis.

Design and simulation of reflective modulators based on semiconductor optical amplifier and electro-absorption modulator

Modulators and amplifiers are the building block of any optical access network. Reflective modulators based on combination of an electro-absorption modulator (EAM) and semiconductor optical amplifier (SOA) are efficient devices for applications in carrier distributed optical access networks due to the gain provided by the SOA and the high speed & low chirp modulation of the EAM. Monolithically integrated reflective EAM-SOAs (R-EAM-SOAs) exhibits excellent performance due to the gain saturation properties of the SOA. Results depict that due to high gain SOA, these devices can be used in a region where the output power is clamped around a maximum value for input carrier powers. In this region of operation, the R-EAM-SOA also exhibits low pattern distortion despite being in a saturated regime. In this paper, we study, analyze and simulate a complete optical communication network using integrated reflective EAM-SOAs (R-EAM-SOAs).
Dynamic Spectrum Allocation for Energy Harvesting-Based Underlaying D2D Communication

In this paper, we model and analyze the resource management problem of energy harvesting-based underlaying device-to-device (D2D) communication in uplink cellular networks (CNs). D2D transmitter can harvest energy from ambient inter- ference and reuse the spectrum of the cellular users (CUs) to com- municate with corresponding receiver. The energy of transmitters comes form the mix of the harvested energy and its battery. To improve the spectrum utilization, one D2D pair should be enable to reuse the spectrum of multiple CUs. In our analysis, dynamic spectrum allocation is applied to minimize the total energy cost of the system with QoS guarantees for both cellular link and D2D link. We first propose a sub- optimal resource allocation scheme while the spectrum bands are static. Then by applying efficient iteration method, we propose the optimal resource management algorithm with dynamic spectrum allocation. Numerical results validate the significant advantages of our proposed schemes in energy harvesting-based D2D underlaying CNs.
A study of walkable spaces with natural elements for urban regeneration A focus on cases in Seoul, South Korea

environmental protection issues and the monitoring of pollution, especially for the largest cities in Asia, are becoming increasingly prominent factors for inclusive urban planning of public open spaces. Recently, a walkability concept was implemented in many cities, and in 2016 it became a campaign direction for development in Seoul. This paper considers conditions of implementation for the walkability concept, using examples of pedestrian walkway-making initiatives, and regeneration of existing walkways along water streams in urban case studies in Seoul, South Korea. The role of nature-based solutions was considered in relation to aesthetics, and social and environmental characteristics (e.g., air pollution, oxygenation through greenery) obtained through literature reviews for the case studies. Considering the complexity of the situation, with factors such as Air Quality Index (AQI) warning conditions, and the general positive impact of walkability on enhancing a healthy life style and social interaction and on reducing congestion, this study contributes to the discussion on walkability, and the importance of nature-based urban regeneration projects for densely populated areas in cities. The results of particular cases in this paper suggest the need for careful monitoring and consideration of various factors for urban regeneration walkable design projects.
Hybrid Modulation Switching Strategy forGrid Connected Photovoltaic Systems

This work presents a novel single phase cascaded H-bridge multilevel inverter with least number of switches and isolated DC sources. The proposed inverter consists of two H-bridges connected in cascade. The upper H-bridge consists of five power electronic switches, capable of developing five level output and the lower H-bridge is capable of developing multilevel output. The conventional CHB inverter is replaced with the additional bi-directional switches in each cell. The proposed inverter consists of two H-bridges, the upper Hbridge is replaced with the addition of one bi-directional switch and the lower H-bridge is replaced with the bidirectional switches driven by hybrid modulation switching strategy. The upper inverter is switched at high frequency and the lower inverter is switched at low frequency. Hybrid modulation switching strategy is used to generate the multilevel output for the proposed inverter. The proposed inverter will be compared with the existing multilevel topologies on the basis of number of components, number of isolated DC sources, Switching losses and converter losses. The proposed inverter will be connected to the grid by proper synchronization along with maximum power point tracking algorithm. The proposed grid connected multilevel inverter will be simulated using MATLAB/SIMULINK and will be implemented in hardware using SPATRAN3A DSP.
Backoff Algorithm in Cognitive Radio MAC Protocol for Throughput Enhancement

In this paper, we have explored a novel concept of the medium access control (MAC) protocol for the distributed cognitive radio network. We have implemented the backoff algorithm in the self-scheduled multichannel cognitive radio MAC (SMC-MAC) protocol for the contention solving among the cognitive users and, hence, reserve the licensed channels for data transmission. In this control channel protocol, the cognitive users share the sensing results with each other, and each channel is divided into four intervals such as idle, sensing-sharing, contention, and data transmission. However, the backoff algorithm has been implemented during the contention interval to enhance the number of successful users and, hence, has increased the throughput of cognitive radio network. The backoff algorithm has significantly minimized the competition and, hence, collision among the cognitive users while reserving the unutilized licensed channels.
An efficient certificateless aggregate signcryption scheme from pairings

A formal model of certificateless aggregate signcryption is proposed, which allows n different users to signcrypt n different messages. Then we propose a concrete certificateless aggregate signcryption scheme. Based on the Bilinear Diffie-Hellman Problem and Computational Diffie-Hellam Problem, the proposed scheme captures indistinguishability of encryptions under adaptively chosen ciphertext attacks (IND-CCA2) and existential unforgeability against chosen message attacks (EUF-CMA) in the random oracle model.
Subepithelial mucinous corneal dystrophy. Clinical and pathological correlations.

We describe a family with an unusual autosomal dominant anterior corneal dystrophy. The onset was characterized by frequent, recurrent corneal erosions in the first decade. This subsided during adolescence and was followed by progressive decreased vision. Slit-lamp examination revealed bilateral subepithelial opacities and haze, involving the entire cornea, but most dense centrally. Histopathological study revealed a subepithelial band of eosinophilic, periodic acid-Schiff-positive, alcian blue-positive, hyaluronidase-sensitive material anterior to Bowman's layer. Electron microscopy demonstrated subepithelial deposition of fine fibrillar material consistent with glycosaminoglycan. Immunohistochemical analysis indicated that the accumulated material contained a combination of chondroitin 4-sulfate and dermatan sulfate. This unique condition clinically resembled Grayson-Wilbrandt dystrophy, but differed histochemically. To our knowledge, this anterior corneal dystrophy has not previously been reported, and it is best described by the name "subepithelial mucinous corneal dystrophy. "
CAPRI: A Critical Assessment of PRedicted Interactions

CAPRI is a communitywide experiment to assess the capacity of protein‐docking methods to predict protein–protein interactions. Nineteen groups participated in rounds 1 and 2 of CAPRI and submitted blind structure predictions for seven protein–protein complexes based on the known structure of the component proteins. The predictions were compared to the unpublished X‐ray structures of the complexes. We describe here the motivations for launching CAPRI, the rules that we applied to select targets and run the experiment, and some conclusions that can already be drawn. The results stress the need for new scoring functions and for methods handling the conformation changes that were observed in some of the target systems. CAPRI has already been a powerful drive for the community of computational biologists who development docking algorithms. We hope that this issue of Proteins will also be of interest to the community of structural biologists, which we call upon to provide new targets for future rounds of CAPRI, and to all molecular biologists who view protein–protein recognition as an essential process.

Overview of the role of molecular methods in the diagnosis of malignant lymphomas.

OBJECTIVE To review the role of molecular genetics in the diagnosis of malignant lymphomas. DATA SOURCES AND STUDY SELECTION Primary research studies and reviews published in the English literature that focus on molecular genetics and malignant lymphoma, in particular, clonality, chromosomal translocations, tumor suppressor genes, and Hodgkin disease. DATA EXTRACTION AND SYNTHESIS Molecular genetics has an important role in the assessment of malignant lymphomas. Clonality, detected by Southern blot analysis or the polymerase chain reaction, is helpful for establishing the diagnosis of lymphoma in lesions with ambiguous morphologic and immunophenotypic findings. Southern blot analysis is the "gold standard" for clonality assessment, but the process is labor-intensive and time-consuming. Polymerase chain reaction analysis is more convenient, but a potentially significant false-negative rate exists in the analysis of some antigen receptor genes as a result of using consensus primers and the process of somatic hypermutation. Chromosomal translocations, which result in oncogene activation, occur in many types of B- and T-cell lymphomas, and their detection is helpful in classification as well as in establishing a diagnosis of malignancy. Gene rearrangements and chromosomal translocations also can be used to monitor minimal residual disease. Tumor suppressor genes, although their analysis is relatively less useful for diagnosis, are involved in both pathogenesis and tumor progression and will be more important diagnostically as this field continues to expand. Molecular genetic analysis has played a major role in improving our understanding of Hodgkin disease. CONCLUSIONS Molecular genetic tests are currently important ancillary tools for the diagnosis and classification of malignant lymphomas, and their role is likely to increase in the future.
Intensification of preoperative chemotherapy for osteogenic sarcoma: results of the Memorial Sloan-Kettering (T12) protocol.

PURPOSE It has been observed previously in osteosarcoma (OS) that the degree of necrosis of the resected primary tumor following a period of preoperative chemotherapy is predictive of subsequent event-free survival (EFS). The aim of this study was to determine if more intensive preoperative chemotherapy would increase the proportion of patients with a good histologic response and improve EFS. PATIENTS AND METHODS Seventy-three patients with OS were treated at Memorial-Sloan Kettering Cancer Center (MSKCC) on the T12 protocol between 1986 and 1993. Patients were randomized between therapy based on the T10 protocol and therapy with more intensive preoperative chemotherapy. The more intensive preoperative regimen consisted of two courses of cisplatin (CDDP) and doxorubicin (DOX) in addition to the usual preoperative regimen of high-dose methotrexate (HD MTX) and bleomycin, cyclophosphamide, and dactinomycin (BCD). RESULTS The regimen with more intensive preoperative chemotherapy achieved a modest increase in the proportion of patients with a good histologic response (44% with a grade III or IV histologic response v 37% in the control arm, 33% with grade IV histologic response v 13% in the control arm). EFS continued to correlate with histologic response. The actuarial 5-year EFS in patients with localized disease was 78% for the regimen with more intensive preoperative chemotherapy and 73% for the control arm. CONCLUSION Despite modest increases in the proportion of patients with good histologic response with intensified preoperative chemotherapy, no improvement in EFS was observed.
Validation of a questionnaire to assess physical activity of children ages 4-8 years.

Three physical activity questionnaires were validated against heart rate (HR) monitoring and motion accelerometer data. All three methods were carried out simultaneously on 62 children ages 4-8 years on 4 consecutive days. The questionnaires were filled in by the children's parents and teachers. The reported time of physical activity with moderate to vigorous intensity, expected to increase HR above 140 beats per minute (bpm), correlated with the time of HR > or = 140 bpm and > or = 150 bpm (r = .40, p < .01) and with the accelerometer score (r = .53, p < .0001). Correlation between the HR > or = 140 bpm and accelerometer score was r = . 45, p < . 001, and between the HR > or = 150 bpm and accelerometer score, it was r = . 41, p < . 01.
A SyR and IPM machine design methodology assisted by optimization algorithms

The design optimization of synchronous reluctance (SyR) machine and its extension to internal permanent magnet (IPM) motors for wide speed ranges is considered in this paper by means of a Finite Element Analysis-based multi-objective genetic algorithm (MOGA). The paper is focused on the rotor design, that is controversial key aspect of the design of high saliency SyR and IPM machines, due to the difficult modeling dominated by magnetic saturation. A three step procedure is presented, to obtain a starting SyR design with the optimal torque versus torque ripple compromise and then properly include PMs into the SyR geometry, given the desired constant power speed range of the final IPM machine. The designed rotors have been extensively analyzed by computer simulations and two SyR prototypes have been realized to demonstrate the feasibility of the design procedure.
Detecting Trends in Social Bookmarking Systems: A del.icio.us Endeavor

The authors present and evaluate an approach to trend detection in social bookmarking systems using a probabilistic generative model in combination with smoothing techniques. Social bookmarking systems are gaining major interest among researchers in the areas of data mining and Web intelligence, since they provide a large amount of user-generated annotations and reflect the interest of millions of people. Based on a vast corpus of approximately 150 million bookmarks found at del. icio.us, the authors analyze bookmarking and tagging patterns and discuss evidence that social bookmarking systems are vulnerable to spamming. They present a method to limit the impact of spam on a trend detector and provide conclusions as well as directions for future research.
Comparison of immunoglobulin (IgG, IgM) concentrations in calves raised under organic and conventional conditions*

The objective of study was conducted on to compare immunoglobulin (Ig) concentrations in calves raised under organic and conventional conditions. 30 newborn Holstein Friesian calves (15 rose under organic and 15 under conventional conditions) in two dairy cattle farms. Blood samples were taken from 30 newborn calves at birth (before taking colostrum) and on 14th day to compare immunoglobulin (Ig) concentrations in calves raised under organic and conventional conditions. Furthermore, blood and colostrum samples were also taken from the mothers included into the study. IgG and IgM concentrations in colostrum and blood serums were determined using commercial ELISA kits. IgG concentrations at birth (0.79±0.34, 1.64±0.95 mg/mL) and on the 14th day (46.5±21.5, 70.5±27.8 mg/mL) in calves raised under organic conditions were lower than those raised under conventional conditions (p 0.05). No difference was found in the IgG and IgM concentrations of colostrum obtained from cows raised under organic and conventional conditions. In both the husbandry systems, positive and significant (p<0.01) correlations were found between the Ig concentrations of the mothers and offsprings. Consequently, it can be suggested that higher Ig concentrations in cattle raised under conventional conditions might be due to poorer environmental conditions.
Comparative analysis between the Stratix II (Altera) and Virtex 4 (Xilinx) for implementing a LVDS bus receiver

Technological advances mean that increasingly faster speeds are required for data transmission between devices, and also better tools and resources are required for connecting devices. When various solutions are available for solving data transmission problems, it is necessary to compare solutions to decide which is best for a given system. This paper compares two families of FPGAs both suitable for implementing an LVDS receiver de-serializer. The paper also describes the various tools that are available with each device for improving performance and increasing data transmission rates.
