Exploiting Spatial Correlation for Improved Prediction in 5G Cellular Networks

—The complexity of the ﬁfth generation of cellular systems (5G) will call for the deployment of advanced Machine Learning (ML) techniques to control and optimize the network. In this paper, we present an application of machine learning to predict the number of users in each base station of a cellular network, based on a dataset with real data collected from hundreds of base stations of a major U.S. national operator. We show that by exploiting the spatial correlation introduced by the mobility of the users it is possible to improve the prediction accuracy with respect to that of completely distributed methods, based on local information only, with a reduction of the prediction error by up to 53%. Finally, we describe a use case in which these predictions are used by a higher-layer application to route vehicular trafﬁc according to network Key Performance Indicators (KPIs).
Estimating Productivity of Manufacturing Sector in Shanghai: A Comparative Study

The manufacturing sector is the foundation of a nation’s industrial structure, and its productivity is closely related to the quality of economic development. The paper uses DEA (Data Envelopment Analysis) models to measure Manufacturing TFP (Total Factor Productivity) and the factors affecting its growth in Shanghai since 1996, and compares Shanghai’s TFP growth with other major manufacturing provinces in China. The results show that Shanghai has no significant advantages over other provinces under the combined action of the internal and external factors. Turning to the development mode driven by the “two-wheel” of both technological progress and technical efficiency is an important way to increase the productivity of manufacturing sector in Shanghai.
Spatial Genetic Patterns in Relation to Regional History and Structure: Gammarus minus (Amphipoda) in Appalachian Watersheds

Populations of Gammarus minus (Amphipoda) at spring and stream sites of 54 small drainage basins in the mid-Appalachian Mountains of central Pennsylvania are highly differentiated genetically at three allozyme loci. Mean heterozygosity, H, is little affected by drainage area, stream density and mean stream gradient. However, H is sig- nificantly correlated with: (1) latitude, with a cline of increasing homozygosity running northward, and (2) distance from the regional trunk stream, with upstream populations most remote from large trunk streams lowest in H. Latitude and trunk stream influences have probably resulted from founder effect operating over recolonizations of vacated habitats. Frequency isopleth surfaces of high frequency alleles are less broadly regional than patterns of H. Some isopleths follow ridgelines, but their modal direction is transverse across valleys, especially along drainage divides. This pattern runs counter to environmental gra- dients and is inconsistent with the operation of natural selection. It supports the hypothesis that surface streams are the main avenues of migration. Spatial correlograms of H and allele frequencies in stream-connected graphs show positive autocorrelation diminishing with distance to 40-60 km. Beyond this radius, correlations are negative or absent.
Adaptive Keyframe and ROI selection for Real-time Video Stabilization

Video stabilization is an important image enhancement widely used in surveillance system in order to improve recognition performance. Most previous methods calculate inter-frame homography to estimate global motion. These methods are relatively slow and suffer from significant depth variations or multiple moving object. In this paper, we propose a fast and practical approach for video stabilization that selects the most reliable key frame as a reference frame to a current frame. We use optical flow to estimate global motion within an adaptively selected region of interest in static camera environment. Optimal global motion is found by probabilistic voting in the space of optical flow. Experiments show that our method can perform real-time video stabilization validated by stabilized images and remarkable reduction of mean color difference between stabilized frames.

The chimeric mice derived from umbilical cord blood stem cells of EGFP-transgenic mouse

Objective The chimeric mice were prepared by microinjection of blastocyst cavity using umbilical cord blood stem cells(UCBSCs) of Enhanced Green Fluorescent Protein(EGFP)-transgenic mouse, which was expected to provide a theoretical and experimental basis for the study of in-vivo differentiation of adult stem cells. Methods Mouse UCBSCs expressing green fluorescence was microinjected into blastocyst cavity and several blastocysts were transferred into uterus of pseudo pregnant mouse. First of all, new-born candidate chimeric mouse were observed through feather color. Secondly, the genomic DNA and total RNA were extracted to analyze chimeric rate in several tissues. Finally, flow cytometry was used to detect percentage of green fluorescent cells mice in several tissues. Results The UCBSCs expressing green fluorescent protein were successfully isolated. After flow cytometry analysis, the proportion of cells expressing green fluorescence was 80.25%. Through microinjection and embryo transfer, we got five white new-born mice and no chimeric feather color was observed. The analyses of PCR and RT-PCR were carried out to detect EGFP gene using six tissues including, heart muscle, liver, lung, skin, leg muscle and adipose tissue. The results showed that the leg muscle and adipose tissue of two mice were positive and the other tissues and six tissues of the other 3 mice were all negative. The leg muscle and adipose tissue of two positive mice were digested into single-cells suspension and were carried out flow cytometry analysis. The Results showed that the average chimeric rates of leg muscle and adipose tissue of two positive mice were 9.87% and 5.78%, respectively. Conclusion The results demonstrated that adult UCBSCs could differentiate into leg muscle and adipose tissue in vivo.
Origine et évolution des races bovines Créoles (Bos taurus) de Colombie

SUMMARY Origin and evolution of criollo cattle breeds (Bos taurus) of Colombia The Creole cattle of America are descended from a reduced number of animals which arrived with Christopher Columbus during his second voyage in November 1493 and mainly from animals introduced later by the conquistadors and the Spanish colonists from the island of Hispaniola (Haiti and Dominican Republic) from where they were introduced in Colombia. These animals of various breeds played a fundamental role in the implantation and the development of cattle breeding in the country until the beginning of the 20 th century. The introduction, from that date, of new bovine breeds was at the origin of a considerable decrease in the number of theses Creole breeds and change in the system of production. Currently, these Creole breeds are now a part of a program of conservation and we intend to use them in pure and cross-breeds for the production of meat and milk in tropical conditions. The genetic studies demonstrate a certain degree of polymorphism which translates a relatively strong variability in breeds with a small number of animals. In a world context of biodiversity preservation this genetic wealth is carrier of hope.

Evaluation of allelopathic potential in rice germplasm

Weeds in paddy are known to reduce rice yield severely. Use of herbicides for weed control has given rise to many problems related to environmental protection, herbicide-tolerant weeds and contamination of agricultural products, which endangered the sustainable development of agriculture. Since last decades, ecological methods for weed control have been developed. Research on rice allelopathy against weeds that started in late 1980's had been encouraging and developed fast. It is one of the first steps for research on rice allelopathy against weeds that involved the screening potential of rice germplasm (Oryza sativa L.). The objective of this research was to determine the allelopathic rice germplasm with both high allelopathic index (AI) and high activity against weeds. Seven rice germplasm (Oryza satica L.) were used as the test materials in this experiment which were primarily screened by bioassay methodology. The allelopathic indices (AIs) were determined with HPLC by the special secondary metabolite marking method, and then, the field experiments were conducted to confirm the weed control effects derived from rice varieties. High allelopathic activity against barnyardgrass (Echinochloa crusgalli L.) of the three rice germplasm (I-Kung-Pao, Parahainakoru from native Taiwan and HB-1 from Mainland China) was detected among the tested rice germplasm. The inhibitory ratios of barnyardgrass root length were 57, 64 and 55%, respectively. The AIs were 0.61, 0.56 and 0.59, respectively, similar to the allelopathic rice PI312777 from the United States considered as control in the experiment. Satisfactory weed control effects in field were obtained as reductions of both the plant density and the fresh weight of barnyardgrass. On short, the rice varieties of I-Kung-Pao, Parahainakoru and HB-1 were regarded as valuable rice germplasm with high allelopathic potential in China.
Toxicological Studies on the Egyptian Cotton Leafworm, Prodenia litura. I. Susceptibility of Different Larval Instars of Prodenia to Insecticides

The susceptibility of the third, fourth, and fifth instars of the Egyptian cotton leafworm, Prodentia litura F. , to 4 insecticides was determined. Acetone solutions of the insecticides were opically applied to the larvae using glass micropipets. The most suitable weight for testing within each instar was determined so as to achieve consistent results. As the larvae increased in age and weight, their susceptibility to insecticides decreased. However, the susceptibility of the unit body weight remained about constant. Observations in the field have always shown that timing of insecticide application is one of the important factors that affect the outcome of spray programs. Much research was conducted to find out the reason for this phenomenon.

Application of Nanotechnology in Cancer Diagnosis and Therapy - A Mini-Review

Cancer is a leading cause of death and poor quality of life globally. Even though several strategies are devised to reduce deaths, reduce chronic pain and improve the quality of life, there remains a shortfall in the adequacies of these cancer therapies. Among the cardinal steps towards ensuring optimal cancer treatment are early detection of cancer cells and drug application with high specificity to reduce toxicities. Due to increased systemic toxicities and refractoriness with conventional cancer diagnostic and therapeutic tools, other strategies including nanotechnology are being employed to improve diagnosis and mitigate disease severity. Over the years, immunotherapeutic agents based on nanotechnology have been used for several cancer types to reduce the invasiveness of cancerous cells while sparing healthy cells at the target site. Nanomaterials including carbon nanotubes, polymeric micelles and liposomes have been used in cancer drug design where they have shown considerable pharmacokinetic and pharmacodynamic benefits in cancer diagnosis and treatment. In this review, we outline the commonly used nanomaterials which are employed in cancer diagnosis and therapy. We have highlighted the suitability of these nanomaterials for cancer management based on their physicochemical and biological properties. We further reviewed the challenges that are associated with the various nanomaterials which limit their uses and hamper their translatability into the clinical setting in certain cancer types.
DOMESTIC INVESTMENT IN PAKISTAN: AN ANALYSIS ACROSS DIFFERENT POLITICAL REGIMES

This study has been conducted to find out the impact of political and economic variables on domestic investment of Pakistan. For this purpose secondary data for 35 years has been collected according to the variables of this study. To analyze the data ARDL bound test procedure has been applied to assess long run relationshipand ARDL based ECM applied to check short run associationof political and economic variables on domestic investment whereas augmented dickey fuller test is applied to check stationary of data. Our findings declared that gross domestic product, foreign direct investment, foreign debt and domestic credit to private sector positively affect domestic investment in Pakistan whereas interest rate, foreign aid, inflation and non-democratic government have negative relation with domestic investment in long run. Dictatorial dummy and credit to private sector has insignificant influence in long run whereas in short run, non democratic dummy influences domestic investment significantly. Results are accordant with classical and Keynesian views. Overall it is concluded that domestic investment decisions have no concern to regime type but political and economic stability and law and order conditions are necessary to promote domestic investment.
The clinical and molecular epidemiology of community-associated Staphylococcus aureus in northern Australia

Staphylococcus aureus is a major human pathogen which has proved versatile in developing resistance to antimicrobials and acquiring virulence factors. Prior to 1990 methicillin-resistant S. aureus (MRSA) was principally a hospital-acquired pathogen, but in the past two decades there has been the global emergence of community-associated (CA) strains of MRSA. Early reports from the Northern Territory, Australia documented high rates of CA-MRSA in Indigenous people. It is unclear why CA-MRSA has emerged in this setting and what relationship CA-MRSA has with the circulating methicillin-susceptible S. aureus (MSSA) strains. The epidemiology of S. aureus and CA-MRSA in northern Australia was described by determining population incidences for S. aureus infection and prospectively collecting S. aureus isolates at the Royal Darwin Hospital. The annual incidence of S. aureus bacteraemia was six times higher in the Indigenous compared to the non-Indigenous population. The disease spectra due to CA-MRSA and MSSA were similar. However, remote residence was associated with CA-MRSA. Irrespective of methicillin-resistance, Panton-Valentine leukocidin (PVL) + isolates appeared more virulent, causing disease in younger, healthier hosts. However, isoforms of PVL conferred no differential clinical effect compared to each other. Diversity was found within the staphylococcal protein A (spa) locus in both CAMRSA and MSSA clonal complex 93 isolates, suggesting multiple independent acquisitions of the methicillin-resistance mediating mecA gene. Molecular typing assays were developed and utilised. These targeted the stable housekeeping genes of the multilocus sequence typing loci, the more rapidly evolving spa locus, and the gene encoding for the pore forming virulence factor PVL. Together, the results support a hypothesis that CA-MRSA has arisen in S. aureus lineages in remote Indigenous communities where staphylococcal disease is highly prevalent. Standard treatment regimens for staphylococcal skin disease may no longer be effective in remote communities and investigations into alternative treatments were commenced.
Intermediary Energy Metabolism during Dormancy and Anoxia in the Land Snail Otala lactea

Metabolic responses to dormancy and anoxia were assessed in foot muscle and he-patopancreas of the land snail Otala lactea (Pulmonata, Helicidae). In both states cellular energetics (arginine phosphate content, adenylate energy charge) were maintained at a high level, fueled during estivation by aerobic metabolism and during anoxia by carbohydrate fermentation. D-lactate was the major product of anaerobiosis in hepatopancreas, but in foot muscle D-lactate, L-alanine, and succi-nate accumulated (in net amounts of 13.5, 3.5, and 1.8 μmolg⁻¹ wet weight, respec-tively). Changes in the concentrations of glycolytic intermediates were compared for both short-and long-term stress: 2 and 14 h of exposure to N₂ gas atmosphere, 3 and 22 d of dormancy at 22° C. Both stresses appeared to include glycolytic activation in the short term in foot muscle, with crossover analyses indicating regulatory control at the phosphofructokinase, aldolase, and pyruvate kinase loci. Over the long term, however, this was reversed and a glycolytic rate depression was observed aspart of the overall metabolic rate depression of these states. In foot muscle, inhibition at phosphofructokinase and pyruvate kinase was apparent during anoxia, whereas aldolase and pyruvate kinase were the key sites of inhibitory control during estivation. In hepatopancreas, phosphofructokinase was the primary locus for inhibitory control during both prolonged anoxia and estivation. These data suggest that common molecular mechanisms underlie glycolytic rate depression during dormancy and anaerobiosis.
Post-Quantum Linkable Ring Signature Enabling Distributed Authorised Ring Confidential Transactions in Blockchain

When electronic wallets are transferred by more than one party, the level of security can be enhanced by decentralising the distribution of authorisation amongst those parties. Threshold signature schemes enable this functionality by allowing multiple cosigners to cooperate in order to create a joint signature. These cosigners interact to sign a transaction which then conﬁrms that a wallet has been transferred. However, in the event of a post-quantum attack, existing threshold signature schemes that support such an authorisation technique in privacy-preserving cryptocurrency protocols - like Ring Conﬁdential Transaction ( RingCT ) - would not provide adequate security. In this paper, we present a new post-quantum cryptographic mechanism, called Lattice-based Linkable Ring Signature with Co-Signing ( L2RS-CS ), which oﬀers a distributed authorisation feature to protect electronic wallets. A novel security model for L2RS-CS is also formalised to capture the security and privacy requirements to protect transactions in applications to blockchain cryptocurrency protocols, such as the RingCT . To address key-generation security concerns, and to support compression of keys and signatures, the L2RS-CS incorporates a distributed key generation along with a solid public-key aggregation. Finally, we prove the security of our constructed L2RS-CS in the random oracle model and the standard lattice-based Module-SIS hardness assumption.

Activated components of parasiticidal Dactylogyrus intermedius extracted from Radix angelicae pubescentis were isolated and purificated by column chromatography and biologica l tracking in this study.The activity in vitro of activated components at different concentrations were determined.Then their chemical structures were identified by TLC,UV,HPLC and GC-MS.Observations implied that the killing effect of the components on D.intermedius at different concentrations were fraction FandK1-2-3.Fraction F could reach to 100% parasiticidal rate when the concentration was 1.6 mg/L.As for K1-2-3,concentrations of 5 mg/L could reach to the parasiticidal rate of 74.9%. According to physico-chemical property examination and spectroanalysis,fraction F and K1-2-3 were identified as the osthole and scopoletine.
Hops β-acids (Humulus lupulus) decrease intestinal gene expression of proinflammatory cytokines in an ex-vivo model

SUMMARY The objective of this study was to evaluate the intestinal gene expression of cytokines in pullets, during the tissue exposure to hops β-acids and lipopolysaccharides (LPS), using an ex-vivo model. To analyze the intestinal gene expression, ileum of pullets was collected, and maintained for 1 hour in Dulbecco's Modified Eagle Medium (DMEM) according to the following 6 treatments: Control (DMEM only); DMEM + 30 ppm of hops β-acids (45%); DMEM + 240 ppm of hops β-acids (45%); DMEM + 30 ppm of hops β-acids (45%) + LPS (10 μg/mL); DMEM + 240 ppm of hops β-acids (45%) + LPS (10 μg/mL) and DMEM + LPS (10 μg/mL). The expression of IL-1β; IL-6; IFN-γ; IL-4 and IL-10 was analyzed using Real Time PCR. The hops β-acids or LPS had no effect on IL-4 and IL-10 expression (P > 0.05). However, hops β-acids decreased IL-1β and IFN-γ expression (P
Mechanisms for heavy metal detoxification and tolerance in algae

With the development of industry and agriculture, more and more heavy metals are released into water bodies. Today, many heavy metals constitute a global environmental hazard. Heavy metals such as copper, zinc, and nickel are essential for many physiological processes yet can be toxic at higher levels. Other metals such as cadmium, mercury and lead are nonessential and potentially highly toxic. Algae possess a range of potential cellular mechanisms that may be involved in the detoxification of heavy metals and thus tolerance to metal stress. These include roles for the following: for sequesteration of metals on extracellular components that reduce metal bioavailability; for chelation of metals in the cytosol by peptides and proteins; for sequestration of metals in polyphosphate bodies; for the compartmentation of metals away from metabolic process by transporting them into the vacuole; for increasing the efflux or exclusion of metals; for producing stress proteins such as heat shock proteins that repair the stress damaged proteins; in addition, some heavy metals cause oxidative stress in algae, with the result that metal toxicity can be altered by synthesis of appropriate enzymes or metabolites counteracting metal induced oxidative stress.In recent years, some attempts to engineer the production of metallothioneins (MTs) and phytochelatins (PCs) in algae to increase metal tolerance and/or accumulation have been reported. To date, however, it is mainly the model plant species that have been genetically engineered. Phytoremediation strategies have been proposed as an attractive alternative owing to their low cost and high efficiency. The concept of phytoremediation of heavy metal contaminated water has been increasingly supported by research. And, algae have been widely used as pollution indicators in water quality determination. Thus, studies on tolerance and detoxification mechanism of heavy metal in algae have numerous ecological and public health implications.
