Toward Consistent SDNs: A Case for Network State Fuzzing

The conventional wisdom is that a software-defined network (SDN) operates under the premise that the logically centralized control plane has an accurate representation of the actual data plane state. Unfortunately, bugs, misconfigurations, faults or attacks can introduce inconsistencies that undermine correct operation. Previous work in this area, however, lacks a holistic methodology to tackle this problem and thus, addresses only certain parts of the problem. Yet, the consistency of the overall system is only as good as its least consistent part. Motivated by an analogy of network consistency checking with program testing, we propose to add active probe-based network state fuzzing to our consistency check repertoire. Hereby, our system, Pazz, combines production traffic with active probes to periodically test if the actual forwarding path and decision elements (on the data plane) correspond to the expected ones (on the control plane). Our insight is that active traffic covers the inconsistency cases beyond the ones identified by passive traffic. Pazz prototype was built and evaluated on topologies of varying scale and complexity. Our results show that Pazz requires minimal network resources to detect persistent data plane faults through fuzzing and localize them quickly while outperforming baseline approaches.
Network Availability of Hybrid FSO/mmW 5G Fronthaul Network in C-RAN Architecture

New innovation approach called -centralized radio access network(Cloud-RAN or C-RAN) - architecture is developed to meet theexplosive growth in mobile traffic in the 5th generation (5G) mobilenetworks especially in the need of high-speed, high capacity, realtimedata, and high-reliability. In C-RAN architecture, fronthaulnetworks connect between the radio units called -Remote RadioHeads (RRHs)- and the processing unit called -Base BandProcessing Unit (BBU)-. Recently, hybrid free space optics (FSO)and millimeter waves (mmW) network is considered to be apromising solution that can match with the requirements of 5Gfronthaul networks. In this paper, hybrid FSO/mmW links at eachRRH is proposed to enhance the performance of C-RAN fronthaulnetwork at various weather conditions. The performance of hybridFSO/mmW technology as a fronthaul network is evaluated atdifferent weather conditions and compared to other technologies.The numerical results reveal that improvements are obtained innetwork reliability using hybrid FSO/mmW fronthaul network,especially at severe weather conditions.
Risk Factors and Efficacy of Adjuvant Therapy After Surgery of Elderly Colon Cancer Patients 70 Years of Age or Older

Background: Colon cancer affects largely elderly populations. Elderly patients treated with adjuvant chemotherapy is lower than younger patients in colon cancer. We aim to evaluate the survival and prognostic factors in accordance with adjuvant chemotherapy in elderly colon cancer patients undergoing curative resection. Methods: We retrospectively reviewed 86 patients 70 years of age or older with stage II, III colon cancer who were underwent surgical resection between 2005 and 2013 at single-center. We examined demographic factors, comorbidities at the time of diagnosis, factors associated with colon cancer, and factors associated with treatment, and analyzed associations survival and these factors divided into adjuvant chemotherapy group (chemotherapy group) and the conservative treatment group (observation group). Results: Among 86 patients 70 years of age or older, 58 patients (67.4%) administered adjuvant chemotherapy and 28 patients (32%) underwent conservative treatment. There are significant differences in respect to the age of 75 in order to select conservative treatment or adjuvant chemotherapy for patients with surgery (p=0.008). There was no significant difference of median overall survival between both groups (chemotherapy group versus observation group: 20 months vs. 24 months, p=0.000). Poor ECOG PS score was independent prognostic factor for overall survival (95% confidential interval 0.016-0.205; hazard ratio, 0.58; p<0.001). Conclusion: Adjuvant chemotherapy did not affect the overall survival in stage II, III elderly colon cancer after surgical resection. There was the tendency to determine whether undergoing adjuvant chemotherapy according to chronologic age. It is thought to be necessary to perform a comprehensive geriatric assessment for decision of adjuvant chemotherapy in elderly patients.
Geopolimer hybrid dibuat dengan mengaktifkan abu terbang menggunakan alkali aktivator dan semen Portland sebagai bahan pengganti sebagian abu terbang untuk perawatan pada suhu ruang. Penelitian ini betujuan untuk mengkaji kuat tekan mortar geopolimer abu terbang hybrid dengan menggunakan semen Portl

Geopolymer hybrid was made by activating fly ash with alkaline activator and Portland cement for replacing fly ash to accelerate curing in ambient temperature. This study aims to examine the compressive strength of geopolymer hybrid mortar using Portland cement, that is OPC (Ordinary Portland Cement) and PCC (Portland Composite Cement). The research procedure began with test the characteristics of the material used, that is fly ash and fine aggregate. The fly ash came from the Ombilin PLTU, Padang. Meanwhile, the fine aggregates came from Teratak Buluh, Kampar. Alkaline activator solutions used were 10M and 12M NaOH, modulus activator ratio (Ms) 1.5 and 2.5. The percentage of replacement of fly ash with cement used is 10% and 15%. The size of the mold used was the cube of 5x5x5 cm. Tests carried out include the mortar compressive strength test. Compressive strength testing was carried out at 7 days and 28 days of curing in ambient temperature. From the test results obtained the optimum compressive strength on geopolymer hybrid mortar was the variation of 10M NaOH, 2.5 and 15% replacement of fly ash with cement at 7 days and 28 days curing in ambient temperature by 8.27 MPa and 13.33 MPa used OPC. Meanwhile, geopolymer hybrid mortar used PCC at 7 days and 28 days by 6.27 MPa and 11.47 MPa. Based on the results, the geopolymer hybrid mortar using OPC has higher compressive strength than using PCC at 7 days to 28 days curing in ambient temperature.
Design, Simulation, Modeling, and Implementation of a Square Helmholtz Coil in Contrast with a Circular Coil for MRI Applications

This paper focuses on Helmholtz-type coils that can produce a second-order homogeneity field to be used for Magnetic Resonance Imaging (MRI) applications. A Helmholtz coil is a device used for producing a region of a nearly uniform magnetic field. It consists of two identical magnetic coils that are placed symmetrically along a common axis, one on either side of the experimental area, separated by a distance equal to the radius of the circular coil and half-length of the side of the square coils. Each coil carries an equal electrical current flowing in the same direction. The main objective of this article is to calculate the magnetic field provided by the coils at any point in space and to show and compare the uniform magnetic field induced by the square and circular Helmholtz coils. With the aid of MATLAB simulation tool, mathematical equations are simulated to demonstrate the axial magnetic field produced by one and two loops. Also, the design and simulation of electrical modeling for square and circular Helmholtz coils are performed using PSPICE. Finally, these coils are realized and tested experimentally, and the results for square and circular Helmholtz coils are compared.

These sites cover the dominant habitats and landscapes present within the study area, and were surveyed during spring, summer and autumn. In addition to these surveys, members of Birds Australia have contributed significantly to the number of fauna records for the study area, as have numerous DEC staff, scientific researchers, and members of the public.
Qualitative study on the effectiveness of community-based methadone maintenance treatment among heroin addicts in some regions of China

Objective To assess the effectiveness of methadone maintenance treatment(MMT)among heroin addicts visiting methadone clinics in Zhejiang,Guizhou,and Sichuan provinces in China.Methods In August 2005,in-depth interviews were undertaken with 30 heroin addicts,15 their family members and 7 health workers.Participants were recruited by doctors from local methadone clinics.After informed consent,face-to-face interviews were conducted in a private location near to the MMT clinics.The interview lasted for 1 to 1.5 hours.All interview records were transcribed and analyzed by ATLAS.5. 0.Results Although a few clients reported that heroin was used stealthily,the cases of using heroin were markedly decreased.Accordingly,heroin-related crimes and HIV related high risk behaviors were substantially reduced.Physical health,self-esteem,emotional well-being,stress,family relationships,normal daily life,employment status and engagement in social activities were improved to various degrees for most clients.Conclusion MMT reduces not only heroin use,drug-related crimes and HIV spread,but also plays a positive role in improving clients' mental and physical health and in rehabilitating their social functions.Therefore,MMT coverage should be quickly expanded so that more drug users may participate in this treatment regime.
Supplementary material to "Radionuclide wiggle-matching reveals a non-synchronous Early Holocene climate oscillation in Greenland and Western Europe around a grand solar minimum"

Several climate events have been reported from the Early Holocene superepoch, the best known of these 21 being the Preboreal oscillation (PBO). It is still unclear how the PBO and the number of climate events observed 22 in Greenland ice cores and European terrestrial records are related to one another. This is mainly due to 23 uncertainties in the chronologies of the records. Here, we present new high resolution 10Be concentration data from 24 the varved Meerfelder Maar sediment record in Germany, spanning the period 11,310-11,000 years BP. These 25 new data allow us to synchronize this well-studied record as well as Greenland ice-core records to the IntCal13 26 time-scale via radionuclide wiggle-matching. In doing so, we show that the climate oscillations identified in 27 Greenland and Europe between 11,450 and 11,000 years BP were not synchronous but terminated and began, 28 respectively, with the onset of a grand solar minimum. A similar spatial anomaly pattern is found in a number of 29 modeling studies on solar forcing of climate in the North Atlantic region. We further postulate that freshwater 30 delivery to the North Atlantic would have had the potential to amplify solar forcing through a slowdown of the 31 Atlantic meridional overturning circulation (AMOC) reinforcing surface air temperature anomalies in the region. 32 33 34 35 36 37 38 39 40 https://doi.org/10.5194/cp-2019-125 Preprint.

Human RSV antigens were detected in nasal/throat swabs in infants with bronchiolitis and pneumonia.
Peran Makerspace di Perpustakaan untuk

Fungsi perpustakaan tidak hanya sebagai tempat menyimpan buku dan berfokus pada pengembangan fisik, tetapi juga berorientasi pada pemberdayaan masyarakat. Kegiatan makerspace di Perpustakaan dapat menjadi salah satu pendekatan efektif kepada pemustaka untuk menciptakan sebuah inovasi dan kreasi bersama. Inilah makna perubahan paradigma perpustakaan ke arah yang lebih baik. Penelitian ini merupakan jenis kajian kualitatif yang bertujuan menganalisis kegiatan makerspace di Perpustakaan Kabupaten Gunungkidul dan menawarkan sebuah model implementasi makerspace berbasis kewirausahaan yang dapat meningkatkan kualitas ekonomi masyarakat. Peneliti melakukan wawancara kepada beberapa informan secara purposive sampling, yaitu Kepala Perpustakaan dan Pustakawan di Perpustakaan Kabupaten Gunungkidul serta anggota pelatihan membatik yang diselenggarakan perpustakaan tersebut. Hasil penelitian menunjukkan bahwa kegiatan makerspace melalui pelatihan ini mampu memberikan kontribusi berupa lingkungan yang kreatif dan menumbuhkan jiwa kewirausahaan bagi para anggota. Namun, kegiatan ini masih belum memberikan kontribusi prototyping dikarenakan perpustakaan belum menyediakan referensi dan informasi memadai tentang desain dan motif batik yang banyak diminati pasar. Selain itu, kegiatan pelatihan membatik ini juga mempunyai hambatan, yaitu kurangnya modal dan promosi. Hal ini yang menyebabkan produk batik yang dihasilkan kurang terdistribusi ke berbagai daerah. Akhirnya, pendapatan yang diperoleh para anggota kurang maksimal. Oleh karena itu, kegiatan membatik yang merupakan kegiatan makerspace perlu didukung oleh komponen-komponen lainnya yang menarik untuk dikaji lebih dalam lagi.
Effects of Lipopolysaccharides (LPS) of Yersinia ruckeri on Immune Response in Rainbow Trout (Oncorhynchus mykiss) by Intraperitoneal and Oral Administration

BACKGROUND: Recently, the researches about herbal medicines as substitutes for chemical drugs have risen in number. OBJECTIVES: To add more aspects to this research area, this study evaluated the changes in biochemical factors of the blood serum due to the consumption of Thymus daenensis extract and the effect of the period of its consumption into the diet of herd dogs. METHODS: Eight adult male dogs were chosen and fed with a fixed diet for 1 month. Then they were ran- domly assigned to two groups of four. The members of first (control) group were fed only with the fixed diet and the second group received 200mg/ml, administered as 1ml/kg of Thymus daenensis extract into their fixed diet. Finally, the dogs were bloodlet at 3 different times, namely before intervention, 7 and 14 days after the in- tervention to measure the factors of glucose, cholesterol, triglyceride, LDL and HDL, alanine aminotransferase and aspartate aminotransferases. RESULTS: Comparing to the control group and the starting point of this experiment, levels of FBS, LDL, TGL, CHOL, AST factors significantly decreased 14 days after intervention, but the HDL factor increased after 7 and 14 days of intervention (P 0.05). CONCLUSIONS: Consequently, oral consumption of Thymus daenensis extract led to decrease in the amounts of glucose and lipids of blood and this herb can be recommended for treating diabetics and persons suffering from high cholesterol.
Pre-monsoon rains and onset of monsoon over the Indochina Peninsula

The rainfall phenomena in the pre-monsoon season over the Indochina Peninsula are investigated using geopotential height, wind and moisture fields by the NCEP/NCAR reanalysis, and OLR, precipitation and GPS data during the GAME-IOP year, 1998. The intermittent rainfall events during the pre-monsoon period are brought in wide region over the central part of the Indochina Peninsula. In early and middle April, and early May, the lower OLR regions, representing the heavy convective activity, extend southward from the mid-latitude zone to the Indochina Peninsula. The composite analysis in these three rainfall events show that these rainfall events are brought by the trough passage in the upper troposphere which migrates eastward in the mid-latitude westerlies along the southern periphery of the Tibetan Plateau. The moisture inflow in the lower troposphere related with these rainfall events is found to come mainly from the south and east, which shows sharp contast with the situations of inflow mainly from the west after the monsoon onset in middle May. Former climatological studies have shown that the summer rainy season starts earlier in the inland area of Thailand and the onset of summer rainy season is prior to the establishment of the summer monsoon circulation over the Indochina Peninsula. Part of such rainfall is shown to be brought by an intermittent rain phenomenon under the mid-latitude westerlies prior to the monsoon onset. keywords: Pre-monsoon rain, Indochina Peninsula, mid-latitude westerly, moisture flux, wind field
Scrutinizing Implementations of Smart Home Integrations

A key feature of the booming smart home is the integration of a wide assortment of technologies, including various standards, proprietary communication protocols and heterogeneous platforms. Due to customization, unsatisfied assumptions and incompatibility in the integration, critical security vulnerabilities are likely to be introduced by the integration. Hence, this work addresses the security problems in smart home systems from an integration perspective, as a complement to numerous studies that focus on the analysis of individual techniques. We propose HomeScan, an approach that examines the security of the implementations of smart home systems. It extracts the abstract specification of application-layer protocols and internal behaviors of entities, so that it is able to conduct an end-to-end security analysis against various attack models. Applying HomeScan on three extensively-used smart home systems, we have found twelve non-trivial security issues, which may lead to unauthorized remote control and credential leakage.
SFI Enhances Therapeutic Efficiency of Gefitinib: An Insight into Reversal of Resistance to Targeted Therapy in Non-small Cell Lung Cancer Cells

Background: The clinical application of EGFR tyrosine kinase inhibitors is always accompanied by inevitable drug resistance. However, the mechanism remains elusive. In the present study, we investigate the involvement of MAPK/SREBP1 pathway in NSCLC gefitinib resistance and evaluate the synergistic effects of shenqi fuzheng injection (SFI) and gefitinib on NSCLC cells. Methods: To investigate the MAPK/SREBP1 pathway involved in gefitinib resistance, Western blotting was used to examine p-MEK, p-ERK and SREBP1 expression in PC-9 and PC-9/GR cells, MTT was used on cell proliferation, wound healing assay was used on cell migration. To detect the cooperative effects of SFI and gefitinib, clonogenic assay was used on cell proliferation. Apoptosis assay was analyzed by flow cytometry. Immunofluorescence was used to detect gefitinib binding to EGFR. Western blotting was used to detect whether SFI regulate the resistance to gefitinib via the suppression of MAPK/SREBP1 pathway. Results: Our results showed that MAPK/SREBP1 pathway mediated resistance to gefitinib in NSCLC cells. MAPK pathway was found to directly target SREBP1 and inhibition of SREBP1 increased gefitinib sensitivity. In addition, SFI showed cooperative anti-proliferation and pro-apoptosis impacts on gefitinib resistant cells via down-regulating MAPK/SREBP1 pathway. Moreover, the combination of SFI and gefitinib enhanced gefitinib binding to EGFR resulting in the restoration of sensitivity to gefitinib. Conclusions: Taken together, MAPK/SREBP1 pathway could be regarded as the potential treatment target for overcoming resistance to EGFR-TKIs in NSCLC and adjuvant therapy of SFI could be a potential therapeutic strategy for gefitinib resistant treatment.
Weight-space symmetry in neural network loss landscapes revisited

Neural network training depends on the structure of the underlying loss landscape, i.e. local minima, saddle points, flat plateaus, and loss barriers. In relation to the structure of the landscape, we study the permutation symmetry of neurons in each layer of a deep neural network, which gives rise not only to multiple equivalent global minima of the loss function but also to critical points in between partner minima. In a network of d−1 hidden layers with nk neurons in layers k = 1, . , d, we construct continuous paths between equivalent global minima that lead through a ‘permutation point’ where the input and output weight vectors of two neurons in the same hidden layer k collide and interchange. We show that such permutation points are critical points which lie inside high-dimensional subspaces of equal loss, contributing to the global flatness of the landscape. We also find that a permutation point for the exchange of neurons i and j transits into a flat high-dimensional plateau that enables all nk! permutations of neurons in a given layer k at the same loss value. Moreover, we introduce higher-order permutation points by exploiting the hierarchical structure in the loss landscapes of neural networks, and find that the number of K-th order permutation points is much larger than the (already huge) number of equivalent global minima – at least by a polynomial factor of order K. In two tasks, we demonstrate numerically with our path finding method that continuous paths between partner minima exist: first, in a toy network with a single hidden layer on a function approximation task and, second, in a multilayer network on the MNIST task. Our geometric approach yields a lower bound on the number of critical points generated by weight-space symmetries and provides a simple intuitive link between previous theoretical results and numerical observations.
