description: In this work, we expand and test the capabilities of our recently developed super-resolution (SR) model to generate high-resolution (HR) realizations of the full phase-space matter distribution, including both displacement and velocity, from computationally cheap low-resolution (LR) cosmological N-body simulations. The SR model enhances the simulation resolution by generating 512 times more tracer particles, extending into the deeply non-linear regime where complex structure formation processes take place. We validate the SR model by deploying the model in 10 test simulations of box size 100 Mpc/h, and examine the matter power spectra, bispectra and 2D power spectra in redshift space. We find the generated SR field matches the true HR result at percent level down to scales of k ~ 10 h/Mpc. We also identify and inspect dark matter halos and their substructures. Our SR model generate visually authentic small-scale structures, that cannot be resolved by the LR input, and are in good statistical agreement with the real HR results. The SR model performs satisfactorily on the halo occupation distribution, halo correlations in both real and redshift space, and the pairwise velocity distribution, matching the HR results with comparable scatter, thus demonstrating its potential in making mock halo catalogs. The SR technique can be a powerful and promising tool for modelling small-scale galaxy formation physics in large cosmological volumes.

description: Recent measurements of the ionizing photon mean free path ($λ_{912}^{\rm mfp}$) at $5 < z < 6$ suggest that the IGM was rapidly evolving at those times. We use radiative transfer simulations to explore the implications for reionization, with a focus on the short value of $λ_{912}^{\rm mfp} = 3.57^{+3.09}_{-2.14}$ cMpc/$h$ at $z=6$. We introduce a model for sub-resolution ionizing photon sinks based on radiative hydrodynamics simulations of small-scale IGM clumping. We argue that the rapid evolution in $λ_{912}^{\rm mfp}$ at $z=5-6$, together with constraints on the metagalactic ionizing background, favors a late reionization process in which the neutral fraction evolved rapidly in the latter half. We also argue that the short $λ_{912}^{\rm mfp}(z=6)$ points to faint galaxies as the primary drivers of reionizaton. Our preferred model, with $λ_{912}^{\rm mfp}(z=6) = 6.5$ Mpc/$h$, has a midpoint of $z= 7.1$ and ends at $z= 5.1$. It requires 3 ionizing photons per H atom to complete reionization and a LyC photon production efficiency of $\log(f^{\rm eff}_{\rm esc} ξ_{\rm ion}/[\mathrm{erg}^{-1} \mathrm{Hz}]) = 24.8$ at $z>6$. Recovering $λ_{912}^{\rm mfp}(z=6)$ as low as the measured central value may require an increase in IGM clumpiness beyond predictions from simulations, with a commensurate increase in the photon budget.

description: Administration of protection mechanisms for large networked information enterprises is challenging due to large numbers of application instances resources and users, complex and dynamic business processes, and high (and always growing) volume of change because of the first two (large scale and dynamics). Significant portion of the complexity and the cost of security administration are due to the ineffective human computer interaction (HCI) models and interfaces employed in security administration.  This talk introduces an upcoming project which goal is to develop better ways of representing cognitive models and find efficient HCI techniques to improve security administration for large-scale networked information enterprises.

description: The article presents an example of the use of functional series for the analysis of nonlinear systems for discrete time signals. The homogeneous operator is defined and it is decomposed into three component operators: the multiplying operator, the convolution operator and the alignment operator. An important case from a practical point of view is considered – a cascade connection of two polynomial systems. A new, binary algorithm for determining the sequence of complex kernels of cascade from two sequences of kernels of component systems is presented. Due to its simplicity, it can be used during iterative processes in the analysis of nonlinear systems (e.g. feedback systems).

description: Recent advances in natural language processing and deep learning have accelerated the development of digital assistants. In conversational commerce, these assistants help customers find suitable products in online shops through natural language conversations. During the dialogue, the assistant identifies the customer's needs and preferences and subsequently suggests potentially relevant products. Traditional online shops often allow users to filter search results based on their preferences using facets. Selected facets can also serve as a reminder of how the product base was filtered. In conversational commerce, however, the absence of facets and the use of advanced natural language processing techniques can leave customers uncertain about how their input was processed by the system. This can hinder transparency and trust, which are critical factors influencing customers' purchase intentions. To address this issue, we propose a novel text-based digital assistant that, in the product assessment step, explains how specific product aspects relate to the user's previous utterances to enhance transparency and facilitate informed decision-making. We conducted a user study (N=135) and found a significant increase in user-perceived transparency when natural language explanations and highlighted text passages were provided, demonstrating their potential to extend system transparency to the product assessment step in conversational commerce.

description: Electrical charges generation occurring during contact and friction of insulating materials has been identified for a long time. However the contribution of these electrical charges to the friction behaviour is usually neglected in the energetical balances. Based on published results and on our own experimental results on the ability of the dielectric materials to trap charges, we show in this study that the interaction energy during friction depends markedly on these trapped charges. Eventually, we propose the complementary use of the "mirror " method and of surface forces measurements to obtain a quantitative evaluation of this contribution. dielectric behaviour / friction / triboelectrification / interfacial interactions / surface free energy / space charge / surface forces
Robust Trust Region for Weakly Supervised Segmentation

description: Acquisition of training data for the standard semantic segmentation is expensive if requiring that each pixel is labeled. Yet, current methods significantly deteriorate in weakly supervised settings, e.g. where a fraction of pixels is labeled or when only image-level tags are available. It has been shown that regularized losses - originally developed for unsupervised low-level segmentation and representing geometric priors on pixel labels - can considerably improve the quality of weakly supervised training. However, many common priors require optimization stronger than gradient descent. Thus, such regularizers have limited applicability in deep learning. We propose a new robust trust region approach for regularized losses improving the state-of-the-art results. Our approach can be seen as a higher-order generalization of the classic chain rule. It allows neural network optimization to use strong low-level solvers for the corresponding regularizers, including discrete ones.

Identification and cloning of DNA affecting production of the adhesive holdfast of Caulobacter crescentus CB2
Creators: name: Mitchell, David Walter
Publisher: name: University of British Columbia
Year: 2010

description: As part of a preliminary investigation into the biological and chemical properties of the freshwater Caulobacter crescentus strain CB2 holdfast (Hf), this research entailed the identification, phenotypic characterization, and cloning of genomic DNA that in some way contribute to the production or regulation of the Hf. Random transposon (Tn5) mutagenesis was used to identify genomic DNA encoding Hf-related functions. A library of approximately 16,000 independently selected mutants (P > 98%) was prepared from which approximately 12,000 colonies (P = 95%) were screened for 77 Hf-mutants that were aberrant in the ability to form large cellular masses adjoined at the Hf (termed rosettes) and/or the ability of colonies to adhere to cellulose-acetate. Ten unique sites of Tn5-insertion were identified from Southern blots of chromosomal DNA from all screened mutants using restriction enzymes that cut once or twice within the Tn5 element. Subsequently, using restriction enzymes that cut frequently or infrequently outside of the Tn5 element, the ten sites of Tn5-insertion were found to be clustered in four genomic regions. Restriction fragments of Tn5-mutated genomic DNA that were shown to contain all of the identified sites of Tn5-insertion within a given cluster were cloned from one representative mutant of each of the four regions. In attempting to ascribe functions to the regions of DNA that encode Hf-related functions, the phenotype of Hf-mutants was investigated on the basis of Hf-adhesiveness to glass and cellulose-acetate and on the basis of lectin-binding to Hf. Four phenotypes were identified: no Hf produced, a low amount of Hf produced, Hf produced and shed into the medium, and a fourth category where a possible alteration of stalk was related to impaired adhesion of the Hf material. The shedding phenotype is of particular interest as a possible means of isolating both wildtype and mutant Hf material for chemical analysis. To this end, a gene replacement strategy was used to transfer a Tn5-mutated DNA fragment cloned from one Hf-mutant into a previously prepared ultraviolet light-induced Hf-shedding mutant. Double mutants confirmed for both shedding and Tn5-induced Hf characteristics were isolated.

description: We consider the nonlinear Schroedinger equation in higher dimension with Dirichlet boundary conditions and with a non-local smoothing nonlinearity. We prove the existence of small amplitude periodic solutions. In the fully resonant case we find solutions which at leading order are wave packets, in the sense that they continue linear solutions with an arbitrarily large number of resonant modes. The main difficulty in the proof consists in solving a "small divisor problem" which we do by using a renormalisation group approach.

description: We use high-resolution hydrodynamic re-simulations to investigate the properties of the thermal Sunyaev-Zel'dovich (SZ) effect from galaxy clusters. We compare results obtained using different physical models for the intracluster medium (ICM), and show how they modify the SZ emission in terms of cluster profiles and scaling relations. We also produce realistic mock observations to verify whether the results from hydrodynamic simulations can be confirmed. We find that SZ profiles depend marginally on the modelled physical processes, while they exhibit a strong dependence on cluster mass. The central and total SZ emission strongly correlate with the cluster X-ray luminosity and temperature. The logarithmic slopes of these scaling relations differ from the self-similar predictions by less than 0.2; the normalization of the relations is lower for simulations including radiative cooling. The observational test suggests that SZ cluster profiles are unlikely to be able to probe the ICM physics. The total SZ decrement appears to be an observable much more robust than the central intensity, and we suggest using the former to investigate scaling relations.

description: We report the discovery of a quadruply imaged quasar, SDSSJ125107.57+293540.5, selected from the Sloan Digital Sky Survey. Follow-up imaging reveals that the system consists of four blue point-like components in a typical cusp lens geometry surrounding a central red galaxy. The source redshift is 0.802 and the lens redshift is 0.410. The maximum image separation between the lensed components is 1"79. While the image configuration is well reproduced by standard mass models with reasonable parameter values, the flux ratios predicted by these models differ from the observed ratios in all bands. This is suggestive of small-scale structures in this lens, although the definitive identification of the anomaly requires more accurate photometry and astrometry.

description: The renormalized contribution of fermions to the curvature masses of vector and axial-vector mesons is derived with two different methods at leading order in the loop expansion applied to the (2+1)-flavor constituent quark-meson model. The corresponding contribution to the curvature masses of the scalar and pseudoscalar mesons, already known in the literature, is rederived in a transparent way. The temperature dependence of the curvature mass of various (axial-)vector modes obtained by decomposing the curvature mass tensor is investigated along with the (axial-)vector--(pseudo)scalar mixing. All fermionic corrections are expressed as simple integrals that involve at finite temperature only the Fermi-Dirac distribution function modified by the Polyakov-loop degrees of freedom. The renormalization of the (axial-)vector curvature mass allows us to lift a redundancy in the original Lagrangian of the globally symmetric extended linear sigma model, in which terms already generated by the covariant derivative were reincluded with different coupling constants.

description: We present a UVES/VLT high resolution atlas of three L dwarfs and one T dwarf system, spectral classes at which most of the objects are brown dwarfs. Our atlas covers the optical region from H$α$ up to the near infrared at 1 $μ$m. We present spectral details of ultra-cool atmospheres at very high resolution ($R \sim 33 000$) and compare the spectra to model calculations. Our comparison shows that molecular features from VO and CaH, and atomic features from Cs and Rb are reasonably well fit by current models. On the other hand, features due to TiO, CrH, and water, and atomic Na and K reveal large discrepancies between model calculations and our observations.

A correlation between the distribution of biological apatite and amino acid sequence of type I collagen
Creators: name: Maitland, Murray E.
Publisher: name: University of British Columbia
Year: 2010

description: The present study was undertaken to examine the distribution of biological apatite within type I collagen fibrils of calcifying turkey leg tendons. The localization of apatite was determined by both bright field and selected-area dark field electron microscopy and was correlated with specific classes of amino acids from chick type I collagen sequence data by computer modelling. These electron microscopic techniques illustrated that apatite occurs in both the gap and overlap zones at early stages of mineralization in an asymmetric pattern which corresponds to the polarized IM- to C- molecular orientation within the collagen fibril. Based on comparisons with theoretical computer images of the known amino acid sequence of collagen it was determined for early stages of mineral deposition that apatite is excluded from areas of high hydrophobic density. The gap zone is less hydrophobic than the overlap zone on average but each of these zones had areas of high density of hydrophobic amino acids which corresponded to sites of low mineral density. Conversely, regions with a high proportion of mineral were low in density of hydrophobic amino acids. The possible interactions between hydrophobic effects and the process of mineral deposition are discussed. In addition, the accommodation of collagen to the deposition of apatite in the overlap zone is discussed.

description: In the traditional cascading architecture for spoken language understanding (SLU), it has been observed that automatic speech recognition errors could be detrimental to the performance of natural language understanding. End-to-end (E2E) SLU models have been proposed to directly map speech input to desired semantic frame with a single model, hence mitigating ASR error propagation. Recently, pre-training technologies have been explored for these E2E models. In this paper, we propose a novel joint textual-phonetic pre-training approach for learning spoken language representations, aiming at exploring the full potentials of phonetic information to improve SLU robustness to ASR errors. We explore phoneme labels as high-level speech features, and design and compare pre-training tasks based on conditional masked language model objectives and inter-sentence relation objectives. We also investigate the efficacy of combining textual and phonetic information during fine-tuning. Experimental results on spoken language understanding benchmarks, Fluent Speech Commands and SNIPS, show that the proposed approach significantly outperforms strong baseline models and improves robustness of spoken language understanding to ASR errors.

description: We study the measurement of Higgs boson self-couplings through $2\rightarrow 3$ vector boson scattering (VBS) processes in the framework of Standard Model effective field theory (SMEFT) at both proton and lepton colliders. The SMEFT contribution to the amplitude of the $2\to3$ VBS processes, taking $W_L W_L\rightarrow W_L W_L h$ and $W_L W_L\rightarrow h h h$ as examples, exhibits enhancement with the energy $\frac{\mathcal{A}^{\text{BSM}}}{\mathcal{A}^{\text{SM}}} \sim \frac{E^2}{Λ^2}$, which indicates the sensitivity of these processes to the related dimension-six operators in SMEFT. Simulation of the full processes at both hadron and lepton colliders with a variety of collision energies are performed to estimate the allowed region on $c_6$ and $c_{Φ_1}$. Especially we find that, with the help of exclusively choosing longitudinal polarizations in the final states and suitable $p_T$ cuts, $WWh$ process is as important as the more widely studied triple Higgs production ($hhh$) in the measurement of Higgs self-couplings. Our analysis indicates that these processes can play important roles in the measurement of Higgs self-couplings at future 100 TeV pp colliders and muon colliders. However, their cross sections are generally tiny at low energy machines, which makes them much more challenging to explore.

description: Possible bound nuclei beyond the two-neutron drip line in the $50\leqslant Z \leqslant 70$ region are investigated by using the deformed relativistic Hartree-Bogoliubov theory in continuum with density functional PC-PK1. Bound nuclei beyond the drip lines of $_{56}$Ba, $_{58}$Ce, $_{62}$Sm, $_{64}$Gd and $_{66}$Dy are predicted, forming peninsulas of stability in nuclear landscape. Near these peninsulas, several multi-neutron emitters are predicted. The underlying mechanism of the peninsulas of stability is investigated by studying the total energy, Fermi surface, quadrupole deformation and the single-neutron spectrum in the canonical basis. It is found that the deformation effect is crucial for forming the peninsulas of stability, and pairing correlations are also essential in specific cases. The dependence on the deformation evolution is also discussed. The decay rates of multi-neutron radioactivity in Ba and Sm isotopic chains are estimated by using the direct decay model.

description: The problem of how many trajectories of a random walker in a potential are needed to reconstruct the values of this potential is studied. We show that this problem can be solved by calculating the probability of survival of an abstract random walker in a partially absorbing potential. The approach is illustrated on the discrete Sinai (random force) model with a drift. We determine the parameter (temperature, duration of each trajectory, ...) values making reconstruction as fast as possible.

This heteroatomic doped CN photocatalyst possesses enhanced visible light absorption, higher charge separation efficiency than pristine CN. Under acidic conditions, cellobiose is not only more efficiently hydrolyzed into glucose but also promotes the syngas and gluconic acid production. Density functional theory (DFT) calculations reveal the favorable generation of •O2− during the photocatalytic reaction, which is essential for gluconic acid production. Consequently, the fine-designed photocatalyst presents excellent cellobiose conversion (>80%) and gluconic acid selectivity (>70%) together with the co-production of syngas (~56 μmol g-1 h-1) under light illumination. The current work demonstrates the feasibility of biomass photoreforming with value-added chemicals and syngas co-production under mild condition.

description: In Europe, equines destined for human consumption (hereafter called slaughter equines) are subject to the same restrictions of usage of veterinary drugs as other food-producing animals, with amendments regulated in the so-called ‘positive list’, Regulation (EC) No. 1950/2006. Due to the complex legal requirements for drug administration in slaughter equines, it might be that specific knowledge regarding the legislation of slaughter equines may be insufficient among veterinarians, equine owners, and equine keepers. To study this assumption, three target group-specific surveys were conducted in 2021. Answers from 153 equine treating veterinarians, 170 equine owners, and 70 equine keepers were included in the analysis. In total 68.4% (91/133) of the participating veterinarians, the regulations of the ‘positive list’, Regulation (EC) No. 1950/2006, were ‘rather complicated’ to ‘complicated’. Among the participating veterinarians, 38.4% (58/151) did not or could not answer correctly how to proceed if a slaughter equine is scheduled to receive phenylbutazone, usage of which is prohibited in all livestock by Regulation (EU) No. 37/2010. Simultaneously, 56.2% (86/153) of the participating veterinarians named phenylbutazone as the, or one of the, most often used non-steroidal anti-inflammatory drugs. Altogether, 41.2% (70/170) of participating equine owners and 42.9% (30/70) of equine keepers did not know under which circumstances an equine can legally be slaughtered for human consumption. In total, 34.3% (24/70) of the equine keepers classified their knowledge of national regulations for animal keepers regarding the documentation of drug usage in equines as ‘poor’ to ‘nonexistent’. This lack of knowledge in all three surveyed groups, combined with the complex legal regulations regarding the usage and documentation of drugs in slaughter equines, could result in missing and false documentation, treatment of slaughter equines with prohibited substances and therefore pose a risk factor for drug residues in equine meat.

description: “One Belt, One Road” is an extensive and complex initiative whose potential effect and influence are

still currently pending for answers. This paper addresses the following research question: What is the

effect of the New Silk Road intercontinental railways on the trade between China and its trading partners

in Central Asia and Europe? We focus on nine railway lines connecting Europe and China, which

started operations between 2011 and 2015. The countries’ trade patterns with railway connections to

China are then compared to the countries without railway connections to China. We find the intercontinental

railways have a positive effect on China’s exports to its trading partners in Central Asia and Europe,

especially concerning exports of manufactured goods, machinery and transport equipment, and

miscellaneous manufactured articles. Moreover, the intercontinental railways have a positive effect on

China’s imports of food and live animals from its trading partners.

description: Novel push–pull dicyanomethylenedihydrofuran(DCDHF)-based chromophores bearing 6-hydroxyl-2,5,7,8-tetramethylchroman-2-carboxylic acid (HTCX) group were synthesized to function as an antioxidant moiety. The preparation of phenylvinyl-bridged DCDHF chromophores with a hydroxyl functional group to be attached HTCX. Due to intramolecular charge transfer (ICT), HTCX-containing DCDHF chromophores showed a distinct solvatochromism in a range of organic solvents. The molecular structures of the prepared HTCX-bearing DCDHF fluorophores were verified by 1H/13C NMR and FTIR spectroscopic analyses. The emission spectra demonstrated dramatic enhancement in the photostability of the prepared fluorophores. Though, the synthesized HTCX/LSHA(Light Stabilizer Hindered Amine)-DCDHF-based hybrids were studied to evaluated antimicrobial efficiency. HTCX-based hybrid DCDHF-8 revealed sensible activity towards (+ve) Gram and (-ve) Gram bacterial strains, and LSHA-based hybrid DCDHF-15 demonstrated good antibacterial effectiveness against B. cereus (+ve gram) and K. pneumoniae (-ve gram) bactria, comparative to Ampicillin reference. Moreover, the theoretical molecular docking stimulation was realistic to sight see their binding connections towards (PDB-1LNZ).

description: The disinfection of commercial hatching eggs before incubation is a common strategy to reduce potential vertical transmission of bacterial and fungal infections from the eggshell to one-day-old chicks that may prevail in poultry products and eventually reach the end consumer. The present investigation focuses on the parallel testing and application of four different disinfection methods (conventional and alternative) under commercial hatchery conditions against natural eggshell bacterial contamination. Hatching eggs from two ROSS 308 broiler breeder flocks were selected and divided into six different groups: two groups were not disinfected and served as negative controls, and four were independently disinfected following product specifications and protocols. From each group, a sample of 100 hatching eggs was selected for bacterial re-isolation, utilizing a modified shell rinse method. Colony-forming units (cfu) from the shell rinse suspensions were determined and analyzed to establish cfu values for each tested egg. These values were analyzed to determine the bacterial disinfection capacity of the four disinfection methods under commercial hatchery conditions. The tested methods were hydrogen peroxide + alcohol, peracetic acid, low energy electron beam, and the gold standard in practice: formaldehyde. Among these methods, formaldehyde, peracetic acid, and low energy electron beam showed a significant difference when compared to the non-disinfected groups whereas hydrogen peroxide + alcohol did not. The bacterial disinfection capacity of the tested methods was compared as well to the gold standard method formaldehyde fumigation and only low energy electron beam achieved similar disinfection levels as formaldehyde. According to our data, three methods significantly reduce the bacterial load on the eggshell of hatching eggs under commercial hatching conditions, including potential alternative methods such as low energy electron beam that perform similar to the gold standard in practice.
Seed germination characteristics of Centaurea diffusa and C. Maculosa

description: The problematic reinfestation of chemically-treated sites by diffuse and spotted knapweed {Centaurea diffusa and C. maculosa) is thought to occur from dormant seeds in the soil. This study confirmed that reserves of dormant seeds are present in the soil of infested sites, although greater numbers of seeds were recovered from senesced plants. Knapweed plants produce both non-dormant and dormant seeds (germination polymorphism), the relative proportions of which vary between individual plants within a site, as well as between bulk samples collected from different sites. Two types of dormant seeds were identified. Dormancy of some seeds was broken by exposure to red light ('light-sensitive seeds'). Light-sensitivity was evident at 10, 15, 20, 25, and 30°C. Germination in light-sensitive seeds was shown to be mediated by phytochrome. A lesser number of dormant seeds failed to respond to red light ('light-insensitive seeds'). Dry after-ripening released dormancy in both light-sensitive and light-insensitive seeds. However, no apparent loss of dormancy from after-ripening occurred when the relative humidity was too low or too high. At the highest relative humidity level tested (90.7%), dormancy was induced in some seeds while other seeds died. Dormancy was also induced when imbibed seeds were incubated in darkness at 25, 30, 35, and 40°C for 5 days. Dormancy induction was greatly enhanced by incubating submerged seeds in de-oxygenated water (anaerobiosis). However, some seeds died when incubated anaerobically for 5 days. Dormancy was broken in a small percentage of dormant seeds by incubation in a 10 mM solution of potassium nitrate or potassium nitrite; 100 mM potassium nitrite killed most seeds. Gibberellic acid was a much stronger germination stimulant. Some dormant seeds germinated at 25 °C if they were previously chilled at 3°C. To compare laboratory findings with field germination behaviour, seeds from two samples of each species were buried to a depth of about 3 cm in mesh packets during November, April and August near Salmon Arm, B.C. Seeds exhibiting higher levels of germination in darkness in vitro also germinated to higher levels in situ when burial occurred in November. However, burial in April and August led to lower germination levels in situ. Light sensitivity was still prominent following 17 months of burial. Most of the decline in viable seed numbers during burial were attributable to in situ germination. Theoretical discussions of the source of germination polymorphism in knapweed seeds, the importance of light to field germination and seedling mortality, and a potential strategy for controlling these weeds are presented.

description: Το λικέρ είναι ένας τύπος οινοπνευματώδους ποτού, που αποτελείται από αλκοόλη γεωργικής προέλευσης, από κάποια γλυκαντική ουσία, συνήθως ζάχαρη και αρωματίζεται με τη προσθήκη φυσικών αρωματικών υλών, όπως είναι τα φρούτα, τα άνθη, τα βότανα, οι ξηροί καρποί, τα καρυκεύματα ακόμα και με προσθήκη κρέμας γάλακτος. Όσο αφορά τα λικέρ από ξηρούς καρπούς, τα πιο σύνηθες είναι αυτα που το άρωμά τους προέρχεται από πικραμύγδαλο και από φουντούκι. Στην παρούσα πτυχιακή αποφασίστηκε να δημιουργηθεί λικέρ του οποίου το άρωμα προέρχεται από έναν πολύ γνωστό ξηρό καρπό, το φιστίκι Αιγίνης. Για αυτόν τον σκοπό παρακάτω εναποτίθενται πληροφορίες για το φιστίκι τόσο στο εξωτερικό όσο και στην Ελλάδα, για τα διάφορα είδη λικέρ και τους τρόπους παρασκευής τους, καθώς και για τα αιθέρια έλαια και τον τρόπο που αντλούνται από τη φύση. Στην συνέχεια ακολουθεί το πειραματικό μέρος όπου, παρασκευάστηκαν κάποια δείγματα λικέρ τα οποία διέφεραν μεταξύ τους τόσο ως προς τον τρόπο αρωμάτισης, όσο και ως προς τον τρόπο που παράχθηκαν. Ουσιαστικά χρησιμοποιήθηκαν ξηροί καρποί, νοποί και ψημένοι αλλά και αιθέριο έλαιο φιστικιού Αιγίνης για την αρωμάτιση τους. Έπειτα με τη βοήθεια εξειδικευμένων δοκιμαστών και βάση ερωτηματολογίου έγινε η οργανοληπτική δοκιμή των διαφορετικών λικέρ, συγκρίθηκαν μεταξύ τους και στη συνέχεια παρατίθενται τα στατιστικά αποτελέσματα που πάρθηκαν από την αξιολόγηση των δειγμάτων καθώς και τα συμπεράσματα που προέκυψαν. Τελικά το μεγαλύτερο ενδιαφέρον εστιάστηκε τόσο στην περιγραφή του χρώματος κυρίως του λικέρ που προήλθε απο εκχύλιση, όσο και στην περιγραφή της γεύσης και της επίγευσης, όπου σε αυτή τη περίπτωση προτιμήθηκαν τα λικέρ που προήλθαν απο αρωματισμό με αιθέριο έλαιο.
