Use of Transposon-Transposase Systems for Stable Genetic Modification of Embryonic Stem Cells

Human stem cells provide new hopes in the clinical treatment of a number of diseases, are excellent models for tissue and cell differentiation, and serve as the basis of new screening systems for drug development and toxicity. Regenerative medicine makes use of cells that can grow and differentiate to replace a damaged tissue. Hematopoietic stem/progenitor cells are successfully applied for bone marrow transplantation in otherwise lethal clinical conditions, while many other cell-based treatments are still experimental. Based on their basic features, we distinguish two major kinds of stem cells. Pluripotent stem cells, capable of differentiating to all types of the cells of human body, were first derived from early human embryos (HuES) and could be grown to provide cell lines with preserved pluripotent characteristics (Thomson et al., 1998). A recently discovered method of generating induced pluripotent stem (iPS) cells from differentiated cell types (Takahashi & Yamanaka, 2006) provides a potential to obtain autologous human stem cell lines without using embryonic tissues. In both cases a major concern, regarding therapeutic applications, is the formation of teratomas, consisting of numerous types of partially differentiated tissues (Reubinoff et al., 2000). Another major source of human stem cells is our own body. Although in a relatively small number, the so called “tissue-derived stem cells”, sometimes referred to as “adult stem cells”, are present throughout our life in various tissues and organs. The “stemness” of these cells, that is their actual stage of differentiation, depends on age, tissue origin and many other still unrecognized conditions. We know that the bone marrow or the cord blood of the neonate contains mostly hematopoietic progenitor cells, the skin, the liver or the intestine has a large number of repopulating epithelial progenitors, and even the muscle or the brain have dormant cells capable of tissue regeneration. Whether our body also contains early cell types similar to the embryonic stem cells, capable of differentiating into any tissue, is still an
Arthropoda of subantarctic islands of New Zealand. 5. Plecoptera

Six gripopterygid stonefly species are found on New Zealand's subantarctic islands. They belong to the genera Apteryoperla and Aucklandobius, which are endemic to New Zealand and those islands. The only winged species, Aucklandobius complementarius Enderlein, is found on the Auckland Islands with A. gressitti n.sp. , Apteryoperla turbotti lilies, and A. kuscheli n.sp. Campbell Island is inhabited by Apteryoperla campbelli lilies and A. longicauda lilies; there is also a doubtful record of Aucklandobius complementarius. All Apteryoperla species except longicauda have terrestrial larvae.
The twelve theories of co‐existence in plant communities: the doubtful, the important and the unexplored

Background: Twelve distinct explanations have been proposed for the co-existence of species in ecological communities. Types of mechanism: The mechanisms can be divided into those that are stabilizing, i.e. with an increase-when-rare mechanism, and those that are equalizing, the latter on their own only delaying the exclusion of species. However, by evening out fitness, equalizing mechanisms can facilitate the operation of stabilizing mechanisms. Importance: It is suggested that circular interference networks, co-evolution of similar interference ability, cyclic succession, equal chance (neutrality) and initial patch composition are likely to be unimportant, or perhaps not even occur. Equal chance is an equalizing mechanism. Allogenic disturbance, alpha-niche differentiation, environmental fluctuation (relative non-linearity and/or the storage effect) and pest pressure are probably important. All four are stabilizing. More evidence is needed on aggregation, interference/dispersal trade-offs and the spatial mass effect. Aggregation and the spatial mass effect are equalizing. Suggestions are made of the evidence needed to make informed judgements on which contribute the most to co-existence in plant communities.
Inter-relationship Between Marine Meiobenthos and Microbes

Meiofauna are benthic metazoans of small size. They form a heterogeneous group of organisms ranging from 38 to 1000 μm in size. Considerable interest was aroused during 1970s and 80s concerning the importance of meiofauna. Much of the meiofaunal life and their characteristics have been reviewed by McIntyre (1969), Coull and Bell (1979) Coull and Giere (1988) and Montagna (1995). All of these authors have pointed out to the need for increased research on meiofauna and microbial interaction. Today, meiofauna is considered a dynamic element of the marine environment and an integral part of the benthic ecosystem. Obviously, then, their importance must continue to be investigated.

The predictive performance of the POSSUM scoring system and early indicatosrs of peripheral perfusion for complications after major abdominal surgery

Postoperative complications are the major cause of postoperative morbidity and mortality and remain to be a serious burden for a healthcare system. The early identification of patients at risk may play a pivotal role in rational decisions regarding perioperative management. The aim of this study was to explore the characteristics of complications in high-risk patients after major abdominal surgery. We also assessed and compared the accuracy of the Clavien-Dindo classification (CDC) and the Comprehensive Complication Index (CCI) for evaluation of postoperative morbidity and the predictive performance of the POSSUM scoring system for complications and mortality. Finally, we wanted to explore the significance of early indicators of altered peripheral perfusion after major abdominal surgery for the occurrence of severe complications. A prospective, observational, cohort study included 206 high-risk surgical patients undergoing major abdominal surgery at the Clinic for Digestive Surgery, Clinical Center of Serbia, from November 2016 to October 2017. We found that the complication rate in our cohort was 60.7% and that the occurrence of complications was associated with the longer ICU stay (p<0.001), postoperative length of stay (p<0.001) and lower functional activity at hospital discharge (p<0.001). The CCI was shown to be of superior accuracy in high-risk patients with multiple complications compared to the CDC as it demonstrated a higher correlation to the resource utilization indicators (p<0.001). The POSSUM scoring system showed the sub-optimal performance for prediction of morbidity and mortality in this cohort of patients (AUCmorbidity= 0.708, O:E ratio=1.07; AUCmortality= 0.744, O:E ratio=0.38). We found that the alterations of peripheral perfusion early after the operation were more pronounced in patients who developed more severe complications. Capillary refill time, central-toperipheral temperature gradient, and venoarterial pCO2 difference to arteriovenous O2 content ratio on admission to the ICU after the operation, as well as serum lactate concentration and base excess 12 hours after the admission to the ICU were the independent predictors of severe complications. Finally, based on the preoperative, intraoperative, and postoperative variables, with the application of the machine learning algorithms, we developed a new model for the prediction of postoperative complications. The model was validated on the new set of patients and it demonstrated an excellent predictive performance (AUC=0.91; sensitivity 92%; specificity 78%; PPV 87%).
Determining Nitrogen Fertilizer Cost Using Turfgrass Response

Numerous nitrogen (N) sources are used in turfgrass management and vary from soluble to slow-release. Determining the least expensive N source can be confusing for consumers. Price per ton and price per pound N are common price comparison methods. An improved approach could use longevity of the N source to balance the price. The objective of this study was to determine the longevity of turfgrass response to N sources and to determine the cost to achieve such responses. This study was conducted in Ft. Lauderdale and Jay, FL, from 1 Jan. to 31 Dec. 2018 on ‘Riley’s Super Sport’ (Celebration®) bermudagrass (Cynodon dactylon). Treatments included nontreated turfgrass, urea, ammonium sulfate, stabilized urea, methylene urea, ureaformaldehyde, two natural organics, sulfur-coated urea, and two polymer-coated urea fertilizers. Treatments were arranged in a split-plot design with N sources as whole plots and N rate (N applied at 49 and 98 kg·ha−1 every 4 months) as subplots. Turf quality was recorded on a scale of 1 to 9, where 1 = dead/brown turf and quality, 6 = minimal acceptable, and 9 = optimal healthy/green turf. Turf quality ratings were recorded weekly and used to determine response longevity (days quality ≥6.0) and area under the turfgrass response curve (AUTRC). Urea resulted in response longevity greater than or equal to other N sources during each season except when applied at 98 kg·ha−1 of N during the fall fertilizer cycle in Jay. Natural organics were ≈6-fold more expensive than urea in Jay and Ft. Lauderdale using turfgrass response longevity and AUTRC. Urea and sulfur-coated urea were the least expensive soluble and slow-release N source, respectively, using dollars per pound N, dollars per acre per day, and dollars per acre per quality-day during each fertilizer cycle and annual average in Jay and Ft. Lauderdale. No evidence was found supporting the use of turfgrass response as a more effective method of determining fertilizer cost than dollars per pound N.
Human T Cell Responses to Dengue Virus Infections: CD8+CTL and Acute Immunosuppression: a Dissertation

There are four serotypes of dengue virus designated dengue 1 , 2 , 3 and 4 (D 1 , D2 D3 and D4) and epidemiological studies indicate that a severe complication of dengue virus infection dengue hemorrhagic fever (DHF) is more likely to occur following a secondar infection. DHF is hypothesized to be immunologically mediated and may be triggered by virus-specific T cells. It is also likely that dengue virus-specific cytotoxic T lymphocytes (CTLs) are important for recovery from dengue virus infections. An analysis of the immune response during acute illness and when the patient has recovered from the infection (immune state) is therefore important as it will provide insights into the immunopathological nature of the disease. This thesis initially examines the CD8+ CTL responses in volunteers who have received live attenuated dengue vaccines and then investigates acute and immune T cell responses in children following natural infection '" . -. --.
Classification on Web Application Requests

This Technology has become ubiquitous and growing, web applications are one of the examples on technology, which are widely used, and deals with a sensitive and huge amount of data, for that these web applications have become a target for many attackers for financial gain, infiltration data, distort the reputation of application, or even for fun. Therefore, it becomes a need to protect web-based applications from attacks, whether known or unknown. This paper discusses the methods of classifying requests in normal and abnormal. It depends on measuring the accuracy of each classification method to know which method will be the best in classifying applications. HTTP DATASET CSIC 2010 contains 61065 of web requests automatically generated, it was developed at the information security institute of Spanish Research National Council CISC, this requests generated from an e-commerce web application, where users register by providing some private information and buy items by their shopping cart. The goal of using this dataset is to present machine-learning techniques in the classifying and predicting the HTTP requests as normal or anomalous traffic. Four classifiers approaches were utilized including: Support Vector Machine (SVM), Decision Trees (DT), Logistic Regression (LR), and Random Forest (RF).
ISAR Target Recognition Using Pix2pix Network Derived from cGAN

Inverse Synthetic Aperture Radar (ISAR) image processing has received much interest in recent years, due to its effectiveness in remote sensing and military use. Although ISAR can achieve all-time all-weather target detection, the quality of images is unstable due to many factors such as sea clutter, which will interfere with target recognition. Since, for sea objects, strong correlation exists between ISAR data and optical camera data, target information extraction accuracy and reliability can be improved by jointly processing the two types of data. In this paper, the pix2pix network derived from the conditional generative adversarial network (cGAN) is used to realize the translation of the ISAR images to the corresponding optical images. In order to remove the influence of lighting conditions on the color of the optical images, we use the grayscale images instead. We combine the generated and the ISAR images to train the CNN network for recognition. Experimental results demonstrate that the proposed method can effectively improve the recognition rate of target recognition based on the ISAR images.
Security Notions for the VeraGreg Framework and Their Reductions

Homomorphic encryption enables computations with encrypted data, however, in its plain form, it does not guarantee that the computation has been performed honestly. For the Fully Homomorphic Encryption (FHE), a verifiable variant emerged soon after the introduction of FHE itself, for a single-operation homomorphic encryption (HE), particular verifiable variant has been introduced recently, called the VeraGreg Framework. In this paper, we identify a weakness of List Non-Malleability as defined for the VeraGreg framework—an analogy to the classical Non-Malleability—and define a stronger variant, which addresses the weakness and which we show not to be strengthenable any more. Next, we suggest a decomposition of the abstract VeraGreg framework, introduce novel notions of security for the resulting components and show some reductions between them and/or their combinations. We conjecture that VeraGreg achieves the strongest (and desirable) security guarantee if and only if its building blocks achieve certain, much more tangible properties. Finally, we suggest a simplification to the original VeraGreg instantiation, which now relies on hardness of particular kind of the famous Shortest Vector Problem for lattices.
Two-Tier Spectrum Trading Strategy for Heterogeneous Cognitive Radio Networks

The heterogeneous network structure is a promising paradigm to improve the quality of service across the entire network. Nevertheless, such structure is challenging due to the presence of multiple-tier secondary users (SUs). In this paper, we investigate the effect of spectrum allocation in a heterogeneous cognitive radio networks with a primary network and two-tier secondary networks, and propose a two-tier spectrum trading strategy which includes two trading processes. In Process One, we model the spectrum trading as a monopoly market, where the spectrum owner (PO) acts as the monopolist and the first-tier secondary users (FSUs) act as the buyers. We design an optimal quality-price contract with the objective of maximizing the utility of PO, and the FSUs will choose the spectrum with appropriate quality and price in order to enhance their satisfaction. In Process Two, the spectrum trading is modeled as a multi-seller, multi-buyer market. The dynamic behavior of second-tier secondary users (SSUs) is studied using evolution game, while the competition among FSUs is analyzed via noncooperative game where the Nash equilibrium is considered as the solution. The existences of the optimal contract and Nash equilibrium are demonstrated in the performance evaluation.
Batch Computing Method for Sensitivity Analysis of Large Power Grids Based on GPU Acceleration

For a given power system operating condition, sensitivity analysis is needed when it is necessary to analyze how the changes of some variables will affect other variables. With the increasing scale of the power grid, it is computationally expensive to perform sensitivity analysis under various operating conditions, such as changes in generation power and line outages. In order to accelerate sensitivity analysis of large-scale power grids, a batch computing method based on graphics processing unit-central processing unit (GPU-CPU) heterogeneous computing framework is proposed. Considering the coarse-grained parallelism of the calculation under different operating conditions and further mining fine-gain parallelism in calculation is an effective approach to improve computational efficiency. This paper proposes a fine-grained parallel batch calculation method to simultaneously obtain line outage distribution factors and generation shift distribution factors under various operating conditions. Finally, by comparing with the standard example, the effectiveness of the proposed method is verified by case study.
Scan Blindness in Finite Microstrip Antenna Arrays

The work considers the problem of scan blindness in microstrip antenna arrays and shows the relationship between the results of analysis carried out with the assumption of infinite antenna array and the results for finite antenna array. The results for infinite arrays obtained using the concept of Floquet modes can be used jointly with empirical results for finite antenna arrays to obtain a method to optimize the parameters of dielectric substrate and the distance between radiating elements to get a scan sector with required scan loss.
Ab-initio Study of Structural, Electronic and Optical Properties of CdS

The structural, electronic and optical properties of wurtzite, zinc blende, and rocsalt phases of the CdS were studied using the DFT method implemented in the WIEN2k code. We used the generalized gradient approximation (GGA-PBEsol) and Becke-Johnson modifies method (TB-mBJ) to calculate the different properties. Structural properties were calculated using the GGA-PBEsol approximation. This method gives the better results for the structural parameters and shows that the wurtzite phase is the most stable under normal temperature and pressure conditions. The other electronic and optical properties were made by utilizing the TB-mBJ method, which is used to approximate the experimental data. These properties show that zinc blende and wurtzite phases have the same electronic and optical properties. These results are in good agreement with the theoretical and experimental values.
A physical model for high resolution radar sea clutter

Sea clutter intensity for high-resolution imaging radars is known to deviate from the classical exponential probability distribution which is observed at low resolution. We use a physical description of sea clutter based on the Two-Scale Model to obtain a relevant expression of the clutter distribution at high-resolution. We test this model with a set of airborne SAR data and show that it provides excellent fits of the intensity distribution in the two polarizations with only one parameter, which is interpreted as a surface mean square slope and is sea state dependent.
