It is known that the interleukin-4 receptorα(IL-4Rα) is highly expressed on the surface of various human solid tumors. We previously designed novel IL-4Rα-lytic hybrid peptide composed of binding peptide to IL-4Rαand cell-lytic peptide and reported that the designed IL-4Rα-lytic hybrid peptide exhibited cytotoxic and antitumor activity bothin vitroandin vivoagainst the human pancreatic cancer cells expressing IL-4Rα. Here, we evaluated the antitumor activity of the IL-4Rα-lytic hybrid peptide as a novel molecular targeted therapy for human biliary tract cancer (BTC). The IL-4Rα-lytic hybrid peptide showed cytotoxic activity in six BTC cell lines with a concentration that killed 50% of all cells (IC50) as low as 5 μM. We also showed that IL-4Rα-lytic hybrid peptide in combination with gemcitabine exhibited synergistic cytotoxic activityin vitro. In addition, intravenous administration of IL-4Rα-lytic hybrid peptide significantly inhibited tumor growth in a xenograft model of human BTCin vivo. Taken together, these results indicated that the IL-4Rα-lytic hybrid peptide is a potent agent that might provide a novel therapy for patients with BTC.

Crystalline metal–organic frameworks (MOFs) are extensively used in areas such as gas storage and small-molecule drug delivery. Although Cu-BTC (1, MOF-199, BTC: benzene-1,3,5-tricarboxylate) has versatile applications, its NO storage and release characteristics are not amenable to therapeutic usage. In this work, micro-sized Cu-BTC was prepared solvothermally and then processed by ball-milling to prepare nano-sized Cu-BTC (2). The NO storage and release properties of the micro- and nano-sized Cu-BTC MOFs were morphology dependent. Control of the hydration degree and morphology of the NO delivery vehicle improved the NO release characteristics significantly. In particular, the nano-sized NO-loaded Cu-BTC (NO⊂nano-Cu-BTC, 4) released NO at 1.81 µmol·mg−1 in 1.2 h in PBS, which meets the requirements for clinical usage. The solid-state structural formula of NO⊂Cu-BTC was successfully determined to be [CuC6H2O5]·(NO)0.167 through single-crystal X-ray diffraction, suggesting no structural changes in Cu-BTC upon the intercalation of 0.167 equivalents of NO within the pores of Cu-BTC after NO loading. The structure of Cu-BTC was also stably maintained after NO release. NO⊂Cu-BTC exhibited significant antibacterial activity against six bacterial strains, including Gram-negative and positive bacteria. NO⊂Cu-BTC could be utilized as a hybrid NO donor to explore the synergistic effects of the known antibacterial properties of Cu-BTC.

In the present work, the porous metal-organic framework (MOF) Basolite®F300 (Fe-BTC) was tested as a potential drug-releasing depot to enhance the solubility of the anticancer drug paclitaxel (PTX) and to prepare controlled release formulations after its encapsulation in amphiphilic methoxy poly(ethylene glycol)-poly(ε-caprolactone) (mPEG-PCL) nanoparticles. Investigation revealed that drug adsorption in Fe-BTC reached approximately 40%, a relatively high level, and also led to an overall drug amorphization as confirmed by differential scanning calorimetry (DSC) and X-ray diffraction (XRD). The dissolution rate of PTX-loaded MOF was substantially enhanced achieving a complete (100%) release within four days, while the neat drug only reached a 13% maximum rate (3–4 days). This PTX-Fe-BTC nanocomposite was further encapsulated into a mPEG-PCL matrix, a typical aliphatic amphiphilic copolyester synthesized in our lab, whose biocompatibility was validated by in vitro cytotoxicity tests toward human umbilical vein endothelial cells (HUVEC). Encapsulation was performed according to the solid-in-oil-in-water emulsion/solvent evaporation technique, resulting in nanoparticles of about 143 nm, slightly larger of those prepared without the pre-adsorption of PTX on Fe-BTC (138 nm, respectively). Transmission electron microscopy (TEM) imaging revealed that spherical nanoparticles with embedded PTX-loaded Fe-BTC nanoparticles were indeed fabricated, with sizes ranging from 80 to 150 nm. Regions of the composite Fe-BTC-PTX system in the infrared (IR) spectrum are identified as signatures of the drug-MOF interaction. The dissolution profiles of all nanoparticles showed an initial burst release, attributed to the drug amount located at the nanoparticles surface or close to it, followed by a steadily and controlled release. This is corroborated by computational analysis that reveals that PTX attaches effectively to Fe-BTC building blocks, but its relatively large size limits diffusion through crystalline regions of Fe-BTC. The dissolution behaviour can be described through a bimodal diffusivity model. The nanoparticles studied could serve as potential chemotherapeutic candidates for PTX delivery.

The usefulness of interspecific crosses between Sitka spruce (Picea sitchensis (Bong.) Carr.) and interior spruce (Picea glauca (Moench) Voss, Picea engelmannii Parry and their hybrids) was investigated in one coastal environment. For height growth and bud set most of the variation was at the regional and individual cross level, but very little variation was at the subregional level. The main genetic effects, male and female, accounted for a majority of the genetic variance and additive genetic effects are interpreted as the main factor in the determination of height growth and bud set. For bud set the maternal source of variation accounted for the majority of the genetic variance and a maternal influence on bud set is suggested. Some specific cross combinations were outstanding in height growth and non-additive genetic factors are considered important in these crosses. For bud break most of the variation was due to the residual error, although regions and crosses were statistically significant sources of variation. The Female*Male term was the most important genetic source of variation although bud break is not considered to have as much genetic variation as height and bud set. Large differences were found in the pattern of cold hardiness in the fall and it is considered that photoperiod plays a much larger role than previously thought, especially for interior spruce. Most of the variation was again at the regional and individual cross level. The intermediate performance of the hybrids suggests an inheritance of cold-hardiness based on additive genetic effects. Recommendations are given in the text for the use of these hybrids as well as the areas in which further research would be desireable.

In the growing field of polycyclic aromatic hydrocarbons (PAHs), the replacement of carbon with isostructural atoms is becoming a versatile functionalisation strategy to tailor the optoelectronic properties of the materials. Among the different dopants, the substitution of C-C pairs by isoelectronic B-N covalent couples leads to isostructural molecular material bearing strong local dipole moments. This imparts a series of physical-chemical properties to the molecule, such as wider HOMO-LUMO gap, the introduction of anchoring points for gas storage and peculiar self-assembly behaviour on metal surfaces. The BN/CC isosterism concept goes back to the seminal discovery of the borazine (H3B3N3H3) by Stock and Pohland in 1926. Thus, in reference to its isoelectronic and isostructural relationship withbenzene, borazine ring is commonly known as “inorganic benzene”. Hence, borazine and its derivatives are valuable molecular modules to be inserted as doping units in graphiticbased carbon materials to tailor their physical-chemical properties. This dissertation focuses on the design, synthesis and characterisation of novel organic materials doped with borazine modules, with the aim of exploring the photophysics, electronics and self-assembly properties of hybrid boron-nitrogen-carbon (BNC)frameworks. Before addressing the detailed investigations of this thesis work, in Chapter I, a brief introduction on the past and recent achievements in the organic synthesis of borazine and its derivatives are given to the reader. This chapter also includes the main synthetic methods used for their functionalisations, as well as their chemical properties and materials applications. Chapter II addresses the design and synthesis of three-branched borazine doped polyphenylenes, in which one or more aryl units are replaced by borazine rings. Owing the possibility of functionalising the borazine ring with different groups on the aryl substituents at the N and B atoms, BNC polyphenylenes were prepared through the decarbonylative [4 + 2] Diels-Alder cycloaddition reaction. To achieve this, two types of molecular modules were synthesised: core and branching units. Therefore, having the possibility of introducing the borazine in different ratios, orientations and positions, three-branched hybrid polyphenylenes featuring controlled orientation and dosages of the doping B3N3-rings were prepared (Figure A.1). At last, the photophysical properties of borazine-doped polyphenylenes have been investigated, describing the relation between the light emission properties and the orientation / dosage doping of these hybrid materials. The second project tackled in this doctoral work is described in Chapter III. Inspiring by the local polar character of the borazine ring, B3N3 scaffold can theoretically interact with polar or polarisable gas molecules, thus making BN-materials promising candidates for tailoring the gas absorptions. In this chapter, the preparation of 3D BN metal organic framework (BN-MOF), composed by three-carboxyl borazine 3-1 as organic linker and [Zn4O(CO)6] as metal cluster is described (Figure A.2). Additionally, to evaluate the effect of the BN doping units in gas storage, the isostructural 3D C-MOF reference, in which the borazine core is replaced by the benzene unit, has been prepared (Figure A.2). The last section of the chapter is dedicated to the description of the X-ray crystal structures of the MOFs as well as their morphology, surface area and thermal stability. Finally, Chapter IV is dedicated to the investigation of three-pyridyl borazine derivatives, amenable to self-assemble and form 2D metal-organic porous network upon deposition on metal surfaces. The first part of the chapter deals with the synthesis of borazine 4-6 through a Suzuki cross-coupling reaction between borazine bearing three-OTf groups and an organoboron pyridyl moiety. The second part describes, by scanning tunnelling microscopy (STM), the tailoring of the 2D self-assembly of borazine 4-6 on Ag(100) and Cu(111) via coordination and thermal treatments. Specifically, densely packed honeycomb network on Ag(100) was observed, whereas interconnected chains were found on Cu(111). Upon deposition of additional Cu atoms at 420 K, a structural transformation can be induced on Cu(111), which leads to a fully three-fold coordinated triangular network (Figure A.3).

Water splitting has been recognized as a promising solution to challenges associated with the intermittent nature of solar energy for over four decades. A great deal of research has been done to develop high efficient and cost-effective catalysts for this process. Among which tantalum nitride (Ta₃N₅) has been considered as a promising candidate to serve as a good catalyst for solar water splitting based on its suitable band structure, chemical stability and high theoretical efficiency. However, this semiconductor is suffered from its special self-oxidation problem under photoelectrochemical water splitting conditions. Several key unique properties of graphitic carbon nitride (g-C₃N₄) render it an ideal choice for the protection of Ta₃N₅. In this work, Ta₃N₅/g-C₃N₄ hybrid photoanode was successfully synthesized. After addition of co-catalyst, the solar water splitting performance of this hybrid photoanode was enhanced. And this protection method could also act as a potential general protection strategy for other unstable semiconductors

Homogeneous catalysts are advantageous in selective catalysis due to the well-defined active site at the molecular level. The poor recyclability, bimolecular aggregation, and undesired poison resistance of homogeneous catalysts hinder further industrial application despite the controlled reaction pathway due to the homogeneous environment. On the other hand, heterogeneous catalysts are preferred in industry due to their high recyclability and high activity. Yet, poor selectivity due to undefined active sites is a drawback. The construction of a host-guest system where a molecular level catalyst is incorporated into the Metal-Organic Framework (MOF) provides a promising solution to bridge those two fields. This composite maintains the advantages of homogeneous and heterogeneous catalysts and overcomes the disadvantages. However, finding an incorporation method that is versatile with minimum synthetic modification of the host and guest remains one of the challenges. In the first part of this dissertation, a new concept called “aperture-opening encapsulation’’ is introduced for incorporating large and diverse guest molecules into MOFs without changing the identity of either the guest or MOF. The approach capitalizes on the existence of linker exchange reactions, which, as our kinetic studies show, proceed via competition between associative and dissociative exchange mechanisms. The second part describes how this method is applied to incorporate a molecular catalyst into the cavity of UiO-66 for the hydrogenation of carbon dioxide to formate, which is a useful application for energy related industry. The developed hybrid composite showed the ability to be recycled, showed no evidence of bimolecular catalyst decomposition, and was less prone to catalyst poisoning. These results demonstrate for the first time how the aperture-opening process resulting from linker dissociation in MOFs can be utilized as a strategy to synthesize host-guest materials useful for chemical catalysis. After the establishment of the hybrid catalyst, the last part of the dissertation describes our efforts into the investigation of mass transport in catalysis. The understanding of the interaction between the host-guest is beneficial for the development of biological analogs in the future

Municipal housing companies (MHCs) can be seen as hybrid organizations, operating under multiple institutional logics that are likely in tension with each other. Measuring the performance of hybrid organizations is a much harder exercise than measuring the performance of pure public or pure private entities. There is a lack of research in this area. To fill this gab van Helden and Reichard’s (2016a) proposed a framework that assigns typical characteristics to PMS in hybrids. The authors call for empirics to test the framework. Accordingly, the first purpose of the thesis is to test the hypotheses of this framework in practice, using a case study approach of two MHCs, MKB AB and LKF AB. The second purpose is to shed light on challenges, conflicts and even propose solutions for MCS/PMS. The thesis ended up by proposing a conceptual model for MCS/PMS that aims to reconcile conflicting goals and logics. The model integrates strategic management control tools (BSC and ERP) to support strategy implementation and formulation as well as to reconcile the different interests of the various stakeholders.

We present the synthesis and characterisation of novel single organic molecules known as phenoxylene borazines and borazatruxenes. Using temperature-dependant and concentration-dependant 1H NMR, we probe the supramolecular aggregation of these molecules in solution. Finally, we synthesise 2D hybrid material comprised of electron delocalised benzene rings and electron localised borazine rings. Using a combination of solid-state 11B and 13C NMR techniques, Raman spectroscopy and XPS, we confirm the presence of benzene and borazine regions in these novel materials.

The use of mobile devices and social media has been increasing dramatically and becoming critical for B2C businesses. Such businesses need to consider implementing e-commerce services in the mobile environment with social integration to satisfy their customers’ needs. Concepts like mobile commerce and social commerce are already being used extensively by many businesses. However, there are no clear guidelines in the literature on how to use mobile and social characteristics together for B2C e-commerce. Fusing these two concepts is what we call mobile social commerce (ms-commerce). In this thesis, we performed a thorough literature review to identify the characteristics of ms-commerce. The findings enabled us to first devise a proper definition for ms-commerce as the concept of performing online commercial activities in a mobile environment with the help of contributions from customers. Second, elements of the building blocks of ms-commerce, namely business models, m-commerce and s-commerce were identified based on commonly accepted fundamentals of the related concepts. Each building block has a critical role in increasing the value and efficiency of the product/service being delivered online by B2C businesses. We propose a mobile social commerce design framework along with a modular design model consisting of a generic class diagram that can be used for designing and developing ms-commerce applications that fit the specific needs of businesses. Businesses can choose the right elements to integrate in their ms-commerce application with the purpose of increasing the efficiency and integrating the social participation of customers. Three different scenarios were devised, and three mobile app prototypes were developed to support them, using the design model of our proposed framework. Finally, in light of our experience in developing ms-commerce applications, we discussed and contrasted the three different mobile development strategies, namely native, hybrid and web-based.

Анотація:

Digital communication systems which use Orthogonal Frequency Division Multiplexing (OFDM) are now widely used and have many advantages. The main disadvantage is the requirement for highly linear analogue electronics including the high power amplifier (HPA). This requirement cannot be met in all circumstances because of the occurrence of symbols with high peak to average power ratio (PAPR). Such symbols may be non-linearly distorted by limiting. Approaches to solve this problem have been either to reduce the PAPR at the transmitter or to try to mitigate the effect of the non-linearity at the receiver. Soft-limiting, i.e. applying limiting in software prior to the HPA is a simple way to reduce the PAPR. It produces non-linear distortion which will cause an increase in the bit-error-rate (BER) at the receiver. This thesis surveys existing alternatives ways of reducing the effect of non-linearity and proposes some new ones. Two iterative receiver techniques, based on statistical analysis of the nature of the non-linearity, have been implemented and investigated. These are the ‘Bussgang Noise Cancellation’ (BNC) technique and the ‘Decision Aided Reconstruction’ (DAR) techniques. As these techniques are valid for any memory-less nonlinearity, an alternative form of limiting, named as Inverted-Wraparound (IWRAP) has been included in the BNC investigation. A new method is proposed which is capable of correcting the received time-domain samples that are clipped, once they have been identified. This is named the ‘Equation-Method’ and it works by identifying constellation symbols that are likely to be correct at the receiver. If there are a sufficient number of these and they are correctly identified, the FFT may be partitioned to produce a set of equations that may be solved for the clipped time-domain samples. The thesis proposes four enhancements to this new method which improve its effectiveness. It is shown that the best form of this method outperforms conventional techniques especially for severe clipping levels. The performance of these four enhancements is evaluated over channels with additive white Gaussian noise (AWGN) in addition to clipping distortion. A technique based on a ‘margin factor’ is designed to make these methods work more effectively in the presence of AWGN noise. A new combining algorithm referred as ‘HARQ for Clipping’ is presented where soft bit decisions are combined from multiple transmissions. ‘HARQ for Clipping’ has been combined with the best version of the Equation-Method, and the performance of this approach is evaluated in terms of the BER with different levels of AWGN. It has been compared to other approaches from the literature and was found to out-perform the BNC iterative receiver by 3dB at signal to noise ratios around 10dB. Without HARQ, the best version of the Equation-Method performs better than the BNC receiver, at signal-to-nose ratios above about 17dB.

Zusammenfassung Damit Deutschland nachhaltiger Wirtschaftsraum bleibt, muss in Forschung und Entwicklung, Geschäftsmodellinnovation und Kompetenzentwicklung im Bereich hybrider Leistungsbündel sowie der Plattform-Ökosysteme breitflächig investiert werden. Dahinter steht das Ziel, Deutschland wieder zu einer der führenden Technologienationen zu machen, denn diese Position hat Deutschland, als die Digitalisierung Einzug erhielt, in vielen Feldern verloren. Nun gilt es, Boden wieder gut zu machen und nach den Bereichen Daten-Hosting und B2C-Plattformen, die fest in US-amerikanischer und chinesischer Hand sind, jetzt das bedeutende Feld der Plattform-Ökonomie zu gestalten, in denen Prozess-Know-how mit Fertigungs-Wissen kombiniert wird, Expertenwissen im Anlagenbau und Produktionsplanung zusammenkommen sowie die Erfahrungen mit produktionsnahen und produktspezifischen Dienstleistungen die Basis hybrider Leistungsbündel darstellen. Der Wettkampf um dieses weltweit bedeutende, weiße Feld auf der Landkarte der webbasierten und mit Plattformen verbundenen Business Ecosystems und mit diesen den hybriden Leistungsbündel im B2B- sowie B2C-Bereich, hat gerade erst begonnen – und Deutschland startet dazu aus einer hervorragenden Ausgangslage. Damit diese Pole-Position ausgebaut werden kann, müssen die technologischen Enabler (Modularität, Konnektivität, Digitaler Zwilling und Autonomie) sowie die Geschäftsmodell-Enabler (Denken in Geschäftsmodellen, Resilienz sowie Wertschöpfungsnetze und Plattform-Ökonomie) konsequent angegangen werden. Dabei wird die Fähigkeit, Kooperationen einzugehen, zu einer Kernkompetenz, denn nur durch das schnelle, flexible Zusammenbringen von Kompetenzen, schaffen wir den eigentlichen und nicht schnell kopierbaren Mehrwert für hybride Leistungsbündel, in denen physische Produkte und smarte Services verschmelzen und neue Geschäftsmodelle ermöglicht werden. Offene Datennetze, die Bereitschaft, Daten zu teilen und Open-Source-Ansätze werden mit diesen Kooperationen zur kritischen Voraussetzung für die Wertschöpfung von heute und morgen. IT Security und Intellectual Property müssen gewahrt bleiben, doch darf die Angst vor dem Missbrauch von Daten nicht dazu führen, dass ad hoc und für spezielle Produkte zu gestaltende Supply Chains nicht organisiert, den wahrgenommenen Kundennutzen bietende Services zu physischen Produkten nicht erstellt oder freie Produktionskapazitäten nicht genutzt werden. „Mehrwert“ heißt morgen „Kooperation“!

AbstractFuSeBMC is a test generator for finding security vulnerabilities in C programs. In Test-Comp 2021, we described a previous version that incrementally injected labels to guide Bounded Model Checking (BMC) and Evolutionary Fuzzing engines to produce test cases for code coverage and bug finding. This paper introduces an improved version of FuSeBMC that utilizes both engines to produce smart seeds. First, the engines run with a short time limit on a lightly instrumented version of the program to produce the seeds. The BMC engine is particularly useful in producing seeds that can pass through complex mathematical guards. Then, FuSeBMC runs its engines with extended time limits using the smart seeds created in the previous round. FuSeBMC manages this process in two main ways. Firstly, it uses shared memory to record the labels covered by each test case. Secondly, it evaluates test cases, and those of high impact are turned into seeds for subsequent test fuzzing. In this year’s competition, we participate in the Cover-Error, Cover-Branches, and Overall categories. The Test-Comp 2022 results show that we significantly increased our code coverage score from last year, outperforming all tools in all categories.

AbstractColombian corporate law has been at the forefront of Latin American systems for the last decade. In 2008, it introduced the simplified corporation (SC), becoming the first country in the region to adopt a hybrid company form. The Colombian legislator has also been a pioneer in the enactment of norms related to benefit corporations introduced by Law 1901 of June 18, 2018 (referred to under the law as benefit and collective interest companies (BICs). Colombian legislation has adopted a highly flexible model of a benefit and collective interest company that does not represent high transaction costs for those entrepreneurs who wish to adopt it. The BIC model has been very successful in Colombia. In fact, the growth of this business model has been exponential within the last few years. It remains to be seen if there will be a convergence between Colombian BIC companies and the few corporations that have been certified by System B in this country.

Non-gray phonon transport solvers based on the Boltzmann transport equation (BTE) are frequently employed to simulate sub-micron thermal transport. Typical solution procedures using sequential solution schemes encounter numerical difficulties because of the large spread in scattering rates. For frequency bands with very low Knudsen numbers, strong coupling between the directional BTEs results in slow convergence for sequential solution procedures. In this paper, we present a hybrid BTE-Fourier model which addresses this issue. By establishing a phonon group cutoff (say Kn = 0.1), phonon bands with low Knudsen numbers are solved using a modified Fourier equation which includes a scattering term as well as corrections to account for boundary temperature slip. Phonon bands with high Knudsen numbers are solved using a BTE solver. Once the governing equations are solved for each phonon group, their energies are then summed to find the total lattice energy and correspondingly, the lattice temperature. An iterative procedure combining the lattice temperature determination and the solutions to the modified Fourier and BTE equations is developed. The procedure is shown to work well across a range of Knudsen numbers.

Self-heating has emerged as a critical bottleneck to scaling in modern transistors. In simulating heat conduction in these devices, it is important to account for the granularity of phonon transport since electron-phonon scattering occurs preferentially to select phonon groups. However, a complete accounting for phonon dispersion, polarization and scattering is very expensive if the Boltzmann transport equation (BTE) is used. Moreover, difficulties with convergence are encountered when the phonon Knudsen number becomes small. In this paper we simulate a two-dimensional bulk MOSFET hotspot problem using a partially-implicit hybrid BTE-Fourier solver which is significantly less expensive than a full BTE solution, and which shows excellent convergence characteristics. Volumetric heat generation from electron-phonon collisions is taken from a Monte Carlo simulation of electron transport and serves as a heat source term in the governing transport equations. The hybrid solver is shown to perform well in this highly non-equilibrium situation, matching the solutions obtained from a pure all-BTE solution, but at significantly lower computational cost. The paper establishes that this new model and solution methodology are viable for the simulation of thermal transport in other emerging transistor designs and in other nanotechnology applications as well.

In this paper we present a novel controller for Shape Memory Alloy (SMA) actuated robotic systems. The new controller, called BAC (B-spline based Adaptive Control), is based on a hybrid combination of gain scheduling, B-spline approximation, variable structure control and integral control. The proposed controller shows excellent positioning accuracy and speed throughout the full range of motion of a SMA actuated robotic system in large-scale applications. To demonstrate the validity of BAC, a novel anthropomorphic SMA Actuated forearm/wrist mechanism is utilized in real-time PC based control experiments. BAC is experimentally compared to PID and integral variable structure controllers and it is shown that its performance is superior.

The use of optical processors for fast numerical calculations has always been hampered by the inherent inaccuracies of analog optics. Numerous techniques have been proposed to overcome this deficiency. One of these, the Bimodal Optical Computer (BOC), proposed by Caulfield et al[1], has generated considerable interest lately. The BOC (shown in fig.l) is a hybrid processor dedicated to solving a set of linear algebraic equations (LAE’s). It consists of an iterative optical processor that uses continuous analog feedback, coupled to a digital processor to ensure high accuracy through a process of iterative refinement.

1. Abstract: Over the past 25 years, vine cacti of the genera Hylocereus and Selenicereus have been introduced into Israel and southern California as new exotic fruit crops. The importance of these crops lies in their high water use efficiency and horticultural potential as exotic fruit crops. Our collaboration focused on the cytological, molecular and evolutionary aspects of vine cacti polyploidization to confront the agricultural challenge of genetic improvement, ultimately to improve success of vine cacti as commercial fruit crop plants. More specifically, we worked on the: 1- Identification of the putative ancestor(s) of the tetraploid H. megalanthus; 2- Determination of the number of origins of H. megalanthus (single vs. multiple origins of polyploidy); 3- Cytogenetic analysis of BC1 and F1 hybrids; 4- Determination of important agricultural traits and the selection of superior hybrids for cultivation. The plant material used in this study comprised interspecific Hylocereus F1 and first backcross (BC1) hybrids, nine Hylocereus species (58 genotypes), nine Selenicereus species (14 genotypes), and four Epiphyllum genotypes. Two BC1 hexaploids (BC-023 and BC-031) were obtained, a high ploidy level that can be explained only by a fertilization event between one unreduced female gamete from the triploid hybrid and a balanced gamete from the pollen donor, the diploid H. monacanthus. These findings are scientific evidence that support the possibility that “hybridization followed by chromosome doubling” could also occur in nature. Cytomixis, the migration of chromatin between adjacent cells through connecting cytoplasmatic channels, was observed in vine cacti hybrids and may thus imply selective DNA elimination in response to the allopolyploidization process. Evidence from plastid and nrDNA internal transcribed spacers (ITS) sequences support the placement of H. megalanthus within a monophyletic Hylocereus group. Furthermore, both plastid and ITS datasets are most consistent with a conclusion that this tetraploid species is an autopolyploid, despite observations that the species appears to be morphologically intermediate between Hylocereus and Selenicereus. Although the possibility of very narrow allopolyploidly (i.e., derivation from parents that are barely diverged from each other such as closely related species in the same genus) cannot be ruled out entirely based on our data (in part due to the unavailability of Hylocereus species considered to be morphologically the closest relatives of H. megalanthus), the possibility of H. megalanthus representing an intergeneric cross (i.e., Hylocereus × Selenicereus) seems extremely unlikely. Interestingly, the process of homogenization of ITS sequences (concerted evolution) is either incomplete or lacking in both Hylocereus and Selenicereus, and the inclusion of several artificial hybrids in the molecular study revealed the potential for biparental plastid inheritance in Hylocereus. The most important agricultural implication of this research project was the information collected for F1 and BC1 hybrids. Specifically, this project concluded with the selection of four superior hybrids in terms of fruit quality and potential yields under extreme high temperatures. These selected hybrids are self-compatible, avoiding the need for hand cross pollination to set fruits, thus reducing manpower costs. We recently offered these hybrids to growers in Israel for prioritized rapid evaluation and characterization.

This scientific article studies natural history documentaries produced by BBC and traces important stages of the development of the attitude towards such genre as natural history documentary. This research is about understanding why this kind of programmes is important, particularly for Ukrainians, and why we should study the genre thoroughly, including the BBC’s experience in the field. Accordingly, the main objectives of the study were: 1. To substantiate the necessity for Ukrainian scholars to study natural history documentaries and BBC’s experience in the field. 2. To trace back and describe the main stages of development in the sphere of producing natural history documentaries by British Broadcasting Corporation. 3. To analyze the obstacles which modern journalists, filmmakers are dealing with and to draw attention of Ukrainian specialists to those philosophical questions that modern era is searching for answers to. In the result of the research these main tasks which were outlined above were fulfilled. The author of this article concluded that natural history documentaries help to understand our place in the world we live in. In addition, through the shared environment we can feel unity with those who inhabit our region, country, inhabited it before, will inhabit in future. Documentaries help us understand who we are. And this function of identification is very important for contemporary Ukraine. To understand how to create proper natural history documentary it’s important to learn the global history of creating such programmes and especially that part which covers BBC’s achievements. The achievements of the corporation which gave birth to such prominent figure as David Attenborough. In addition to this, the article described some modern challenges which documentary makers face and those questions which contemporary society needs to have answered. Because you cannot create a proper natural history programme if you know past but do not know modern challenges. To sum up, the topic which is deeply connected with process of self-identification is very important and perspective for Ukrainian society which suffers hybrid war and endeavours of Russian Federation to assimilate Ukrainian people, Ukrainian culture.

An experimental study was carried out to characterize the scavenging behavior of a cross-scavenged, piston-aspirated, two-stroke, natural gas engine to aid in the development of computationally inexpensive simple scavenging models for onboard engine control by (1) studying the effects of changing operational parameters on the engine's scavenging performance, and (2) identifying the underlying phenomena driving the observed effects. Tracer based methods were used to quantify the scavenging and trapping performance of the engine - CO2 was used as a tracer for combustion products and pre-mixed fuel was used as a fresh charge tracer. CO2 concentration was measured on a crank angle resolved basis both in the engine cylinder and exhaust using portable NDIR sensors, while unburned fuel concentration was measured in the exhaust using the FID module of a standard five gas analyzer. It was found that scavenging took place in three stages, an initial perfect displacement type stage, followed by a short-circuiting, and a perfect mixing type stage. Engine speed and load changes were found to have the strongest effects on the trapping and scavenging performance of the engine; spark timing effects were less significant. Changes in measured scavenging and trapping efficiencies at different operating points resulted from a combination of influences, namely (1) reduced time for gas exchange at high speeds, (2) higher expansion and scavenging pressures at high loads and retarded spark timings, and (3) phasing of the reflected 'scavenging' and 'plugging' pulses in the exhaust pipe relative to BDC and EPC, respectively. Increasing engine load made the engine scavenge significantly better and increasing engine speed resulted in a larger fraction of the delivered air being trapped. The combined effect of these scavenging changes and changes in the engine's fuel conversion efficiency resulted in the engine running leaner at high speeds (more air delivered and higher trapping efficiency) and at low loads (higher trapped residuals). The results were then used to gauge the performance of the simple scavenging model (the hybrid model) developed in phase II of the project. While encouraging results were obtained at high speed, the trapped air mass was overestimated at medium speed; suggesting the need for adding a low scavenging efficiency sub-model. Recommendations have been made about adding a short-circuiting zone to address this limitation of the model.

To achieve higher brake thermal efficiency (BTE) and improve vehicle economy, the new development of dedicated hybrid engine (DHE), adopting the Atkinson or Miller cycle, has been becoming the current development trends. A base 1.5L natural aspiration (NA) engine with deep Atkinson cycle has been developed for dedicated hybrid vehicle application, which can achieve the highest BTE of 41.19%. In order to achieve higher BTE, several potential technologies which are easy for mass production application have been studied progressively, such as, higher compression ratio (CR), optimized exhaust gas recirculation (EGR) pick point, lower EGR temperature, higher EGR rate, higher RON number fuels, heat transfer reduction by polishing valve head, light boost, lower viscosity oil. The results show the combined technology application can achieve the highest engine BTE of 42.59%. This paper provides the studied technical routine and the achieved benefits step by step.
