Abstract:
Replication protein A (RPA) is a complex of three polypeptides of 70, 34, and 13 kDa isolated from diverse eukaryotes. The complex is a single-stranded DNA-binding protein essential for simian virus 40-based DNA replication in vitro and for viability in the yeast Saccharomyces cerevisiae. We have identified a new 30-kDa human protein which interacts with the 70- and 13-kDa subunits of RPA, with a yeast two-hybrid/interaction trap method. This protein, Rpa4, has 47% identity with Rpa2, the 34-kDa subunit of RPA. Rpa4 associates with the 70- and 13-kDa subunits to form a trimeric complex capable of binding to single-stranded DNA. Rpa4 is preferentially expressed in placental and colon mucosa tissues. In the placenta, Rpa4 is more abundant than the 70-kDa Rpa1 subunit and is not associated with either Rpa1 or with any other single-stranded DNA-binding protein. In proliferating cells in culture, Rpa4 is considerably less abundant than Rpa1 and Rpa2. Northern (RNA) blot analysis suggest that there are alternatively processed forms of the RPA4 mRNA, and Southern blot analysis indicates that beside RPA4 there may be other members of the RPA2 gene family.

Abstract:
ABSTRACT Menin is a 70-kDa protein encoded by MEN1, the tumor suppressor gene disrupted in multiple endocrine neoplasia type 1. In a yeast two-hybrid system based on reconstitution of Ras signaling, menin was found to interact with the 32-kDa subunit (RPA2) of replication protein A (RPA), a heterotrimeric protein required for DNA replication, recombination, and repair. The menin-RPA2 interaction was confirmed in a conventional yeast two-hybrid system and by direct interaction between purified proteins. Menin-RPA2 binding was inhibited by a number of menin missense mutations found in individuals with multiple endocrine neoplasia type 1, and the interacting regions were mapped to the N-terminal portion of menin and amino acids 43 to 171 of RPA2. This region of RPA2 contains a weak single-stranded DNA-binding domain, but menin had no detectable effect on RPA-DNA binding in vitro. Menin bound preferentially in vitro to free RPA2 rather than the RPA heterotrimer or a subcomplex consisting of RPA2 bound to the 14-kDa subunit (RPA3). However, the 70-kDa subunit (RPA1) was coprecipitated from HeLa cell extracts along with RPA2 by menin-specific antibodies, suggesting that menin binds to the RPA heterotrimer or a novel RPA1-RPA2-containing complex in vivo. This finding was consistent with the extensive overlap in the nuclear localization patterns of endogenous menin, RPA2, and RPA1 observed by immunofluorescence.

Abstract:
Regarding high-level and complex decision-making scenarios, the study presents an extensive approach to the Simple Aggregation of Preferences Expressed by Ordinal Vectors-Multi Decision Making method (SAPEVO-M). In this context, the modeling proposal, named SAPEVO-Hybrid and Hierarchical (SAPEVO-H²), the objective of this study, based on the concepts of multi-criteria analysis, provides the evaluation of alternatives under the light of multiple criteria and perceptions, enabling the integration of the objectives of a problem, which are transcribed into attributes and structured in a hierarchical model, analyzing qualitative and quantitative data through ordinal and cardinal entries, respectively. As a case study, a decision analysis concerning the defense strategies against anti-Remotely Piloted Aircraft Systems (RPAS) strategies for the Brazilian Navy is carried out. Using the technique of the causal maps approach based on Strategic Options Development and Analysis (SODA) methodology, the problematic situation is structured for numerical implementation, demonstrating the performance of objectives and elements of a hierarchical structure. As a result, rankings concerning objectives and anti-RPAS technologies, based on the treatment of subjective information, are presented. In the end, the main contribution of the study and its limitations are discussed, along with the conclusions and some proposals for future studies.

Abstract:
In this paper, on the basis of multifunctional reconfigurable pixel antenna (RPA) elements, a novel linear sparse array with an attractive compound reconfigurability is presented. It has the potential advantages of its beam scanning with low gain fluctuation, low sidelobe in two orthogonal planes, and polarization reconfigurable performance. Specifically, an RPA with simultaneous polarization and pattern reconstruction capabilities, consisting of the driven patch and the parasitic pixels on the same layer of dielectric substrate, is firstly designed, which can work in several operation modes corresponding to steerable beam directions θ=0°;θxoz=25°, 45°;θyoz=15° with two circular polarizations in X-band. Cross-slot coupling feed is used to improve polarization reconstruction capability and reduce the complexity of hybrid reconstruction topology optimization. Then, those RPAs are integrated into the 1×8 linear sparse array to realize the reconfiguration of two circular polarizations and beam steering in xoz- and yoz-plane. Simulation results show that the gain fluctuation and sidelobe level of the array during beam scanning have significant advantages over the previous phased array, and the generation of antenna grating lobes is avoided. Moreover, both RPA element and RPA array prototypes have been fabricated and measured to testify the efficiency. The measured results agree well with the simulated ones, which indicates the application potential in the field of modern wireless communication system of the proposed linear sparse array.

Abstract:
This paper addresses the issue of developing a computerized system for processing information in the construction of the trajectory of an unmanned aircraft (UAC), a remotely-piloted aviation system (RPAS), or another robotic system. Resolving this task involves the neural network learning algorithms based on the mathematical model of movement. The construction of such a trajectory between two specified destinations has been considered that provides for the possibility of bypassing static and dynamic obstacles. The specified trajectory is divided into several smaller parts. The possibility of restructuring when changing the position of obstacles in space has been considered. A UAC flight control algorithm has been developed, which implies training a neural network for bypassing obstacles of different sizes. To predict the development of the situation when an object moves between two specified points in space, it is proposed to use the Q-Learning algorithm. It has been shown that the smallest number of steps required for moving along a specified trajectory is 18, the largest is 273 steps. In case of distortion during data transmission, the training of the neural network makes it possible to reduce the possibility of collision with obstacles by improving the accuracy and speed of information transfer between the on-board computer and operator. A system of the video support to moving objects was modeled; dependence charts of the normalized frame size at different parameter values were built. Using the charts makes it possible to determine the function of the maneuver intensity. Existing neural network learning methods such as CNN and LSTM were compared. It has been proven that the success rate reaches 74 % when using CNN only, while it amounts to 92 % at the hybrid application of CNN+LSTM. The simulation results have demonstrated the high efficiency of the developed algorithm

Abstract:
A series of Trifolium ambiguum x T. repens hybrid populations has been developed at the hexaploid (four T. repens and two T. ambiguum genomes) and pentaploid (four T. repens and one T. ambiguum genome) level. When tested for effectiveness of symbiotic nitrogen fixation, the 6x and 5x hybrids nodulated with either T. repens or T. ambiguum strains of rhizobia but only formed an effective N- fixing symbiosis with a mix of T. repens rhizobia strains. When grown in the field, the 6x and 5x hybrid plants had a similar morphology to white clover in that the hybrids grew surface stolons (fewer numbers than white clover) and no underground rhizomes. The advantage of the 6x hybrid was deeper roots and a greater proportion of root, a characteristic considered important for greater drought tolerance and persistence than for white clover. The 6x hybrid indicated 55% of the seed production potential of white clover, but there was large variation between plants in all reproductive traits. The 5x hybrid showed poor levels of seed set. The growth pattern of the 6x hybrids in the field indicated lower herbage yield in the first year but improved performance compared with white clover into the second year. At this early stage, the hybrid breeding populations consist of unselected and novel hybrid combinations. Variations in growth and reproductive characteristics exist between hybrid plants, thus providing scope for improvement through selection and breeding.

Abstract:
Neotyphodium is an asexual, vertically transmitted, obligate fungal endosymbiont infecting cool-season grasses such as Arizona fescue. The relationship between Neotyphodium and several native grass hosts ranges from antagonistic to mutualistic. One theory that may explain how Neotyphodium infection is maintained despite inconsistent mutualistic benefit to the host is the bounded hybrid superiority hypothesis. This hypothesis argues that hybrids are more fit than non-hybrids in response to some environmental stresses. Neotyphodium infects hosts in both hybrid and non-hybrid forms. We tested the possibility of hybrid superiority in depauperate habitats (low soil water and nitrate) by quantifying the types and frequency of host infections (uninfected, hybrid-infected and non-hybrid-infected), and the quality of resources available between three host populations. A second theory, the geographic mosaic theory of coevolution, may also explain different symbiotic outcomes at the population level in response to variation in abiotic and biotic population characters. We provide cursory support for both hypotheses. Keywords: geographic mosaic theory of coevolution, hybrid, Festuca, Neotyphodium, symbiosis, mutualism, bounded hybrid superiority

Abstract:
A ryegrass breeding programme to improve the seasonal growth and plant persistence of perennial and hybrid ryegrasses in the Waikato began at AgResearch Ruakura, Hamilton in 2001. One approach was to characterise the genetic diversity of the naturalised populations within 26 dairy farms from different districts around the Waikato and Bay of Plenty (BOP) regions. Plants from 26 individual breeding lines were evaluated as single spaced plants over a 3-year period in comparison with three commercialised ryegrass cultivars. Principal Component Analysis was used to order the plant populations in accordance with the observed plant variables of seasonal growth pattern, tillering ability, leaf size and extension, and the incidence of crown rust. A hierarchical cluster analysis of the wild populations revealed two distinct plant groups. A mix of large leaf Italian Lolium multiflorum and hybrid plants were typical from the warmer drier areas of the BOP. The Italian ryegrass was prone to severe crown rust infection whereas the hybrids were more resistant. Shorter, narrow leaved and densely tillered plants with a high rust infection dominated the Waikato populations. Ecotypes that maintained high plant tiller density throughout the seasons had the best persistence. Plants that displayed an improvement in seasonal yield and tillering over the commercial cultivars were considered an important genetic source to develop new persistent cultivars for the Waikato and BOP regions.

Abstract:
Deer are seasonal animals with a feed intake that varies with day length, reaching a low in winter. Feed intake then rises rapidly in spring. Superimposed on the nutritional response to day length are the genetics of the deer. This paper documents preliminary findings of live weight gain in winter and spring and intake during September for red deer (Cervus elaphus) and elk (Cervus elaphus canadensis) x red deer hybrids. Two experiments examined the relative growth rates and feed intake of rising 1 year old red and elk x red hybrid male deer during winter and spring 2001 and 2002. Live weight gain was higher in the elk x red than the red deer in both winter (averaging 262 and 144 g/d respectively) and spring (averaging 390 and 272 g/d respectively). Dry matter intake in September 2001 was 1.64 and 2.13 kg DM/d for red and elk x red deer respectively (P=0.003). Dry matter intake in September 2002 averaged 2.04 and 2.35 kg DM/d (P

Abstract:
Replication Protein A (RPA) [Replication Factor A (RFA) in yeast] is an ssDNA binding protein composed of Rpa1, Rpa2, and Rpa3 and involved in numerous DNA processing pathways such as Replication, Recombination, and Repair. It participates in such diverse pathways by its ability to interact with numerous proteins. The goal of my project was to find novel RPA-protein interactions using the yeast two hybrid assay. Using this method, we identified several known and unknown proteins that interact with Rfa1 and showed that these interactions were dependent on the phosphorylation state of Rfa2. Next, we determine the region important for interaction between Rfa1 and Rad24. Rad24 is a checkpoint protein important for initiation of the DNA damage checkpoint signaling. By using the β- galactosidase assay, we determined the N-terminal region of Rfa1 (DBD-F) and the C-terminal region of Rad24 (460-660 aa) to be necessary for their interaction.

In this chapter we discuss the typology of drones that are currently being used for different kinds of environmental and conservation applications. Drones are also commonly known variously as Remotely Piloted Aircraft Systems (RPAS), Unmanned Aerial Vehicles (UAV), and Unmanned Aircraft Systems (UAS). We focus on the most popular aircraft types including multirotor (of various configurations), fixed wing, and hybrid ‘vertical-take-off-and-landing’ (VTOL) craft, and briefly discuss the relative pros and cons of each type. We also broadly discuss the essential components common to all remotely piloted aircraft systems, including the power source, flight controller (or autopilot), and ground control station.

Abstract:
In last period, the technology development has experienced accelerated and extreme growth resulting in many concepts such as: blockchain, quantum technology, Robotic Process Automation (RPA), Artificial Intelligence (AI) and Machine Learning (ML), Internet of Things (IoT), edge computing, Virtual Reality (VR) and Augmented Reality (AR), and 5th (5G) and 6th (6G) generation networks. This trend is increased by the SARS-CoV-2 pandemic, given that the technology enabled continuance of affairs. In parallel, the threats and attacks on cyber security have dramatically increased as well, causing many losses of all kinds. These two trends need to be treated combined for the purpose of timely and proper addressing and solving of security issues and challenges in the context of future technologies. Therefore, this work contributes by providing a brief overview of cyber security perspective, i.e. challenges and issues for top future technologies. The conducted analysis has shown that security issues for future technologies are numerous and need to be treated in systematic and organized manner during the design of technologies and products in order to minimize the risk and damage and maximize the utilization and benefit.

It aims to present trends brought to the working environment using technologies and tools to manage people and their knowledge. Firstly, the authors aim to specify selected areas of HR management influenced by the development of information technologies based on the literature review and a professional opinion. Four areas were selected: a hybrid world of work, robotic/intelligent process automation (RPA/IPA), talents, and knowledge management in the digital era. The research statements were prepared for the round table discussion with experts and a survey using the CAWI method. Practitioners' opinion was compared with theoretical findings and statements. Despite the research limitations, the results bring topical information and complement the professionals' views. Overall, respondents agree that discussed trends in HR bring new opportunities, freedom, and flexibility, but also some challenges. RPA/IPA solutions free people from routine work and give space for creativity.

Abstract:
Laser/plasma interaction experiments have generally suffered from poor focal spot quality. This problem is a direct result of the coherence of the laser. A number of different methods1,2 have been developed to modify the coherence properties of the laser in an attempt to produce a smooth focal spot profile. In designing a scheme suitable for Vulcan a number of constraints have to be considered: the laser system must remain flexible to meet the needs of a broad based user community; the focal spot requirements differ significantly between the different groups and all have to be catered to; and the cost of any scheme has to be limited. The method chosen was a combination of induced spatial incoherence (ISI) and random phase plates (RPP). To produce ISI a short coherence length oscillator is used. To generate spatial incoherence transparent echelons are placed at the output of the rod amplifier chain before the final disk amplifier stages. This method as used on Vulcan has a limit on the size of focal spots available. A second smoothing method is therefore used: RPPs are inserted into each beam to control the divergence of the laser. This hybrid approach to focal smoothing has proved extremely successful.
