Low frequency assist for mmWave backhaul - the case for SDN resiliency mechanisms

In 5G, network densification is a major concern for operators. When a massive amount of small cells are deployed, the backhaul capacity is crucial and researchers are exploring the use of high frequency bands such as 28, 60 or even 140 GHz because of the large portion of spectrum that is available. Unfortunately, such mmWave links frequently change their capacity due to blocking and weather phenomena which makes it challenging to design stable multihop backhaul networks using those frequency bands. In this paper, we investigate the use of Software Defined Networking (SDN) for the operation and control of wireless backhaul networks. We explore different ways how SDN resiliency mechanisms such as FastFailover Groups can be used to mitigate disruptive connectivity in the multihop operation due to mmWave links frequently failing. We also demonstrate a clear benefit for using low frequency assist mode, where the small cell has an additional stable LTE uplink to the eNB that is used should the mmWave backhaul links fail. Our experiments using a network emulator show that such SDN based local repair mechanisms can significantly reduce the packet loss rate inside the mmWave backhaul mesh, which can be further reduced with an LTE assisted Failover.
Electronically Stabilized Copoly(Styrene-Acrylic Acid) Submicrocapsules Prepared by Miniemulsion Copolymerization

This work reports the preparation and characterization of poly(styrene-acrylic acid) (St/AA) submicrocapsules by using the miniemulsion copolymerization method. AA was introduced to miniemulsion polymerization of St to increase the zeta potential and the resulting electrostatic stability of St/AA submicrocapsules. Phytoncide oil was adopted as the core model material. Miniemulsion copolymerization of St and AA was conducted at a fixed monomer concentration (0.172 mol) with a varying monomer feed ratio [AA]/[St] (0.2, 0.25, 0.33, 0.5, and 1.0). Concentrations of initiator (azobisisobutyronitrile; 1.0 × 10−3, 2.0 × 10−3, 3.0 × 10−3, and 4.0 × 10−3 mol/mol of monomer) and surfactant (sodium dodecyl sulfate; 0.6 × 10−3, 1.0 × 10−3, and 1.4 × 10−3 mol) were also controlled to optimize the miniemulsion copolymerization of St and AA. Dynamic light scattering and microscopic analyses confirmed the optimum condition of miniemulsion copolymerization of St and AA. Long-term colloidal stability of aqueous St/AA submicrocapsule suspension was evaluated by using TurbiscanTM Lab. In this work, the optimum condition for miniemulsion copolymerization of St and AA was determined ([AA]/[St] = 0.33; [SDS] = 1.0 × 10−3 mol; [AIBN] = 2.0 × 10−3 mol/mol of monomer). St/AA submicrocapsules prepared at the optimum condition (392.6 nm and −55.2 mV of mean particle size and zeta potential, respectively) showed almost no variations in backscattering intensity (stable colloids without aggregation).
Reducing Roadmap Size for Network Transmission in Support of Cloud Automation

This work aims to highlight the benefits of Cloud Automation for industrial adopters and some of the research challenges that must be addressed in this process. The focus is on the use of cloud computing for efficiently planning the motion of new robot manipulators designed for flexible manufacturing floors. In particular, different ways that a robot can interact with a computing cloud are considered, where an architecture that splits computation between the remote cloud and the robot appears advantageous. Given this synergistic robot-cloud architecture, this work describes how solutions from the recent literature can be employed on the cloud during a periodically updated preprocessing phase to efficiently answer manipulation queries on the robot given changes in the workspace. In this setup, interesting tradeoffs arise between path quality and computational efficiency, which are evaluated in simulation. These tradeoffs motivate further research on how motion planning should be executed given access to a computing cloud.
Concurrent dual-frequency oscillator using a dual-band filter

A novel concept of designing concurrent dual-frequency oscillator based on dual-band filter as the frequency selective feedback network is presented in this paper. A trisection stepped-impedance resonator with dual-band response is used as a frequency determining circuitry in the feedback loop of an amplifier to realize a dual-frequency oscillator. The designed oscillator generated concurrent oscillations at 2.48GHz and 5.4GHz. Phase-noise values of −114dBc/Hz and −104dBc/Hz are obtained at 1MHz offset from lower and upper frequencies, respectively.
[Adiponectinemia, inflammatory process activity, and endothelial dysfunction in patients with type 2 diabetes and acute coronary syndrome with ST elevation in relation to the severity of lesions in the coronary arteries].

INTRODUCTION Metabolic disorders developing in diabetes are associated with impaired endothelial function and the presence of subclinical inflammation, in consequence leading to generalized atherosclerosis. Vasoprotective factors include adiponectin, a cytokine with a diverse antiatherosclerotic activity. OBJECTIVES Evaluation of adiponectin concentrations and activity of the inflammatory process and endothelial dysfunction in patients with type 2 diabetes and acute coronary syndrome (ACS) with ST elevation (STEMI) in relation to the severity of lesions in the coronary arteries. PATIENTS AND METHODS This study included 72 patients (24 women, 48 men) with type 2 diabetes, treated with sulphonylurea derivatives, diagnosed with STEMI, who underwent percutaneous coronary angioplasty. The treated group consisted of 41 patients, mean age (+/- standard deviation) was 64 +/-9.6 years, the Gensini score (GS) >32 points (more advanced lesions in the coronary vessels). The control group consisted of 31 patients, a mean age of 63 +/-10 years, GS <32 points (less advanced lesions). Within 12 hours after the ACS, serum troponin T activity (TnT), creatine kinase MB isoenzyme (CK-MB), C-reactive protein (CRP), fibrinogen, two adhesion molecules - soluble vascular adhesion molecule-1 (sVCAM-1) and soluble intercellular adhesive molecule-1 (sICAM-1) were evaluated in serum of the patients. Leucocytosis, glucose and insulin levels, and lipid profiles were obtained after overnight fast conditions. RESULTS Patients in group I demonstrated a significantly higher TnT and CK-MB (1.39 +/-1.3 vs 0.83 +/-0.74 ng/ml, p <0.05; 139.6 +/-178.5 vs 57.48+/-52.1 IU/I p <0.05, respectively), higher concentrations of CRP (12.06 +/-14.3 vs 3.59 +/-4.1mg/l, p <0.05) fibrinogen (4.59 +/-1.93 vs 3.62 +/-1.36 g/l, p <0.05), sVCAM-1 (1393.4 +/-865.4 vs 863.9+/-425.2 ng/ml, p <0.05) and sICAM-1 (735.1+/-316.3 vs 573.3 +/-226.1 ng/ml, p <0.05), higher leucocytosis (11,430 +/-3680 vs 9750+/-3100/microl, p <0.05) and lower adiponectin concentrations (5.8 +/-5.2 vs 8.3 +/-2.9 8 microg/ml, p <0.05) as compared to the control group. CONCLUSIONS Hypoadiponectinaemia, severity of the inflammatory process and endothelial dysfunction could be factors contributing to the progression of atherosclerotic lesions in the coronary arteries in patients with type 2 diabetes.

Intelligent decision-making through a simulation of evolution

A computer replaces the Galapagos Islands as the authors take finite-state machines through a simulated process of evolution and natural selection. Random mutation of an arbitrary machine yields an offspring. The machines then compete and, given available history and a goal to achieve, the machine that gets the higher score thus survives as the fittest and is selected as the new parent. Mutation and selection are continued, with real-time decisions being based upon the logic of the surviving machines.

Microblog Sentiment Orientation Detection Using User Interactive Relationship

The development and popularity of microblog have made sentiment analysis of tweets and Weibo an important research field. However, the characteristics of microblog message pose challenge for the sentiment analysis and mining. The existing approaches mostly focus on the message content and context information. In this paper, we propose a novel microblog sentiment analysis framework by incorporating the social interactive relationship factor in the content-based approach. By exploring the interactive relationship on social network based on posted messages, we build social interactive model to represent the opposition or acceptation behavior. Based on the interactive relationship model, the sentiment of microblog message with sparse emotion terms can be deduced and identified, and the sentiment uncertainty can be alleviated to some extent. Afterwards, we transform the classification problem into an optimization problem. Experimental results on Weibo data set indicate that the proposed method can outperform the baseline methods.
Humoral responses to Malassezia furfur serovars A, B and C in normal individuals of various ages

A transferable solid‐phase (TSP) ELISA was developed for the determination of antibody titres specific to Malassezia furfur serovars A, B and C in human sera. A survey of levels of class‐specific antibodies (IgM, IgG and IgA) to M. furfur serovars A, B and C in relation to age (2–64 years: 60 individuals) demonstrated that individuals had immunity to M. furfur by the age of 2–3 years. There was no difference in either IgM or IgG levels into adulthood. The only age‐related differences were lower IgM titres to the three serovars in the 60–64 year age‐group compared with younger individuals. There was, however, a difference between titres of antibody specific to the three serovars. The mean reciprocal log2 IgM titre to serovar A (6·9) was significantly higher (P < 0·05) than that to serovar B (mean reciprocal log2 titre of 5·8), but not to serovar C (6·1). In contrast, the mean reciprocal log2 IgG titre to serovar A (6·5) was significantly lower (P <0 ·05) than those to serovars B and C (mean reciprocal log2 titre of 8·9 in both cases).
Combination of polymorphisms from genes related to estrogen metabolism and risk of prostate cancers: the hidden face of estrogens.

PURPOSE The association between common functional polymorphisms from the CYP17, CYP19, CYP1B1, and COMT genes involved in the estrogen metabolism and the risk of prostate carcinoma was evaluated. PATIENTS AND METHODS The study investigated 1,983 white French men (1,101 patients with prostate cancer and 882 healthy controls) aged between 40 and 98 years. The different alleles and genotypes were analyzed according to case-control status, aggressiveness pattern of the tumors, age at onset, and family history of cancers. RESULTS The VV (high activity) genotype of the V432L polymorphism from CYP1B1 (odds ratio [OR] = 1.36; 95% CI, 1.03 to 1.79; P = .031), and the long allele (> 175 bp) of the TTTA repeat from CYP19 (OR, 1.26; 95% CI, 1.08 to 1.47; P = .003) were significantly associated with the risk of prostate cancer. An additive effect was observed when we combined the two at-risk alleles (OR = 1.63; 95% CI, 1.24 to 2.13; P < .001). The association was stronger for the CYP1B1 VV genotype (OR = 1.55; 95% CI, 1.13 to 2.13; P = .007) among the group of patients with highly aggressive disease. Stratification by age at onset showed that the associations of CYP1B1 and CYP19 variants were largely confined to the younger prostate cancer patients. CONCLUSION This association between polymorphisms from genes related to estrogen metabolism and prostate cancer risk suggest new clinical considerations in the management of prostate cancer: the development of new prevention trials based on genetic profiling and the evaluation of specific inhibitors involving the estrogen pathways.
Are Bilateral and Multilateral Aid‐For‐Trade Complementary?

Using the first comprehensive estimates of ad valorem tariff equivalent bilateral trade costs spanning the time period 2002&#8211;10, we examine whether the aid&#8208;for&#8208;trade (AFT) inflows reduce bilateral trade costs facing aid recipients. If so, we ask whether the trade costs reduction effects of AFT from bilateral and multilateral sources are complementary. By showing the extent to which the observed trade cost reduction effects of AFT from bilateral (multilateral) sources correlate with the magnitudes of AFT disbursements from multilateral (bilateral) sources, we present plausible explanation for the cross&#8208;country variations in the extent to which AFT promotes trade flows. Our findings have, thus, important policy implications for shaping future discourses on the coordination of disbursements for enhancing the effectiveness of AFT.
Morphological analysis and lemmatization for Swiss German using weighted transducers

With written Swiss German becoming more popular in everyday use, it has become a target for text processing. The absence of a standard orthography and the variety of dialects, however, lead to a vast variation in different spellings which makes this task difﬁcult. We built a system based on weighted transducers that recognizes over 90% of the tokens in certain texts. Weights ensure preferring the best analysis for most words while at the same time allowing for very broad range of spelling variations. Our morphological tagset that we deﬁned for this purpose and lemmas in Standard German open the possibility for further processing. Besides our morphological analyzer and lemmatizer, a morphologically annotated corpus offers new resources for Swiss German and helps spreading our tagset.
Control of Biofouling In Marine Environment - Past, Present And Future

Biofouling is a worldwide phenomenon plaguing mariners and accounting for economic burden on shipping, aquaculture and various other maritime industries. The fouling organisms cause extensive damage to commercially important marine structures causing increased drag of marine surface and submarine vessels incurring increased fuel penalties. Antifouling is the phenomenon of preventing biofouling. Conventionally the principal protective method against fouling has been the use of antifouling paints. Environmental concerns of high toxicity against non- specific targets including marine flora and fauna have resulted in imposition of worldwide ban on the use of most chemical antifouling formulation including TBT in 2006. Currently, other available approaches are far from ideal and consequently they do not provide a complete or long term answer to this expensive problem. Consequently exploration for alternatives coating has been intensified to bridge the gap. Great deal of attention is being currently focused on identification of nontoxic, environmentally friendly, Natural Product Antifouling agents (NPA).
Compositional differences among female‐associated and embryo‐associated microbiota of the viviparous Pacific Beetle cockroach, Diploptera punctata

ABSTRACT All cockroach species, except one, harbor the endosymbiont Blattabacterium, transmitted from females to embryos. Adult cockroaches acquire non‐Blattabacterium bacteria as part of their gut microbiota over time, but our knowledge of the possible transmission of these non‐Blattabacterium bacteria from females to embryos is rudimentary. We characterized the gut microbiota of gravid viviparous Diploptera punctata females and the non‐Blattabacterium microbiota of associated developing embryos, as well as the gut microbiota of non‐gravid females, and the microbiota of orphan embryos (females not included), following high‐throughput sequencing of the 16S rRNA gene to assess bacterial transference. We determined significant differences in community composition between gravid females and associated embryos and overall greater similarity in community composition among embryos than adult females. Results suggest various routes of transference of bacteria from females or the environment to embryos. The bacterial families Halomonadaceae and Shewanellaceae were more abundant in embryos than in gravid females. The functional relevance of these families remains to be elucidated, but provisioning of amino acids deficient in the brood sac secretion is a possibility. Overall, our results highlight the need for further studies investigating the uptake and selective screening of microbes by D. punctata embryos, as well as their functions. &NA; Graphical Abstract Figure. Diploptera punctata females and their corresponding developing embryos differ in microbiota composition.
Limbic and Motor Function Comparison of Deep Brain Stimulation of the Zona Incerta and Subthalamic Nucleus

BACKGROUND: Psychiatric and neuropsychological side effects of subthalamic nucleus (STN) stimulation have been increasingly recognized. Most programming regimens focus on contacts 0 and 1, whereas contact 3, which often is located near or in the zona incerta (ZI), is usually not used. The question of whether ZI stimulation may limit limbic effects has not been answered. OBJECTIVE: To examine the effects of short-term stimulation near or in the ZI (contact 3) compared with stimulation of the STN using standard trajectories and targeting as measured by limbic and motor functions. METHODS: Motor and limbic functions of 11 patients with STN DBS were assessed with the Unified Parkinson Disease Rating Scale-3, structured gait video analysis, Visual Analog Scale mood scales, task testing of impulsivity, and facial recognition under routine STN programming and under stimulation in or near the ZI. Postoperative magnetic resonance imaging confirmed the location of contact 3 near or in the ZI. RESULTS: Data analysis with repeated-measures analysis of variance revealed that motor scores remained stable with both stimulation settings, with specific improvements in finger taps (P = .02) and rapid alternating movements (P = .03) in ZI stimulation. Stimulation near or in the ZI led to a decrease in self- reported anxiety and depression (P = .03 for both) and an improvement in fear recognition (P = .02). CONCLUSION: We provide preliminary evidence that stimulation in or near the ZI results in maintained motor function while improving self-reported depression and anxiety in patients with bilateral STN DBS. Stimulation in or near the ZI may provide a useful programming setting for patients prone to psychiatric side effects.
Inter- and intra-individual variations of urinary endogenous metabolites in healthy male college students using 1H NMR spectroscopy

Abstract Background: Most human metabolomics studies have shown that spectral outputs of 1H nuclear magnetic resonance fingerprinting are strongly influenced by inter- and intra-individual variations; however, few studies have been performed to evaluate the inter- and intra-individual variations in urinary endogenous metabolites. Methods: We recruited 30 male college students to evaluate the factors affecting intra- and inter-individual variations in urinary endogenous metabolites. Statistical analysis for variations in urinary metabolites was performed after eliminating outliers found in principal component analysis (PCA) plots. Results: Inter-individual variations were relatively low for 2-oxoglutarate, succinate, citrate, dimethylglycine, and taurine, but high for trimethylaminoxide (TMAO), hippurate, and lactate. Intra-individual variations for 2-oxoglutarate, citrate, dimethylglycine, and taurine were relatively low, but high for TMAO and hippurate. The factors affecting inter-individual variation of lactate were age, body mass index, beverages, and alcohol, whereas the factors affecting intra-individual variation of lactate were age and fish. Kim Chi intake affected the inter-individual variation of succinate, citrate, TMAO, and hippurate; however, it did not affect the intra-individual variation of endogenous metabolites. Conclusions: Our results showed that inter- and intra-individual variations in urinary endogenous metabolites were very large, and significant factors affecting inter- and intra-individual variation were diverse, even after eliminating outliers in PCA analysis.

Mutations in the trfA replication gene of the broad-host-range plasmid RK2 result in elevated plasmid copy numbers

Mutated forms of trfA, the replication protein gene of plasmid RK2, that support a minimal RK2 origin plasmid in Escherichia coli at copy numbers up to 23-fold higher than normal have been isolated. Six such high-copy-number (copy-up) mutations were mapped and sequenced. In each case, a single base transition led to an amino acid substitution in the TrfA protein primary sequence. The six mutations affected different residues of the protein and were located within a 69-base-pair region encoding 24 amino acids. Dominance tests showed that each of the mutants can be suppressed by wild-type trfA in trans, but suppression is highly dependent on the amount of wild-type protein produced. Excess mutant TrfA protein provided in trans significantly increased the copy number of RK2 and other self-replicating derivatives of RK2 that contain a wild-type trfA gene. These observations suggest that the mutations affect a regulatory activity of the TrfA replication protein that is a key factor in the control of initiation of RK2 replication.
Spice-accurate systemC macromodels of noisy on-chip communication channels

With the advent of nanoscale technologies, even RTL and system designers must consider interconnect analysis to provide predictable performance, reliability and meet power budgets. However, system-wide modeling of high-speed interconnects using conventional circuit simulators such as SPICE can become prohibitively CPU expensive. We propose to formulate analytical interconnect macromodels capturing noise effects, and to integrate them into the SystemC communication abstractions. Experimental results show that HDL simulations achieve an average accuracy of 5% from SPICE, while a few case studies illustrate the applicability of the proposed framework for fast exploration of physical channel configuration and performance estimation.
