description: We aim at an augmentation of communication abilities of amyotrophic lateral sclerosis (ALS) patients by creating a brain-computer interface (BCI) which can control a computer or other device by using only brain activity. As a method, we use a stimulus-driven BCI based on vibration stimuli delivered via a gaming pad to the user's back. We identify P300 responses from brain activity data in response to the vibration stimuli. The user's intentions are classified according to the P300 responses recorded in the EEG. From the results of the psychophysical and online BCI experiments, we are able to classify the P300 responses very accurately, which proves the effectiveness of the proposed method.

Revealing the onset of star-formation by studying high-redshift clumpy galaxies with ALMA
Creators: name: Anita Zanella
Publisher: name: Zenodo
Year: 2024

description: Star-forming galaxies at z ~ 2 - 4 seem to be more gas-rich  than local galaxies and to have gravitationally-unstable interstellar medium. Simulations predict that such conditions allow the formation of massive star-forming regions, dubbed "clumps", 100 times larger and more massive than local star-forming regions. While clumps have been extensively studied at UV and optical wavelengths, their molecular gas and dust reservoirs have hardly been observed and are still poorly constrained. We tackled these open questions by investigating the [CII] and dust morphology of a z ~ 3.4 lensed galaxy hosting four clumps detected in the UV continuum. We conducted ALMA observations probing scales down to ∼ 300 pc and detected three [C II] clumps, while we do not detect the dust continuum. We used the [CII] luminosity as a tracer of molecular gas, as recently suggested by severeal observational and theoretical studies, to estimate the star formation efficiency of clumps and investigate their location in the Schmidt-Kennicutt plane. This revealed that clumps span a range of SFE, likely depending on their evolutionary phase (early formation vs more evolved ages). These observations suggest that multi-wavelength observations ranging from the UV to the FIR are key to understand the onset of star formation and the role of clumps in galaxy evolution. I will conclude the presentation by discussing future prospects and developments.

description: Non-trivial topology of phase is crucial for many important physics phenomena such as, for example, the Aharonov-Bohm effect 1 and the Berry phase 2. Light phase allows one to create "twisted" photons 3, 4 , vortex knots 5, dislocations 6 which has led to an emerging field of singular optics relying on abrupt phase changes 7. Here we demonstrate the feasibility of singular visible-light nanooptics which exploits the benefits of both plasmonic field enhancement and non-trivial topology of light phase. We show that properly designed plasmonic nanomaterials exhibit topologically protected singular phase behaviour which can be employed to radically improve sensitivity of detectors based on plasmon resonances. By using reversible hydrogenation of graphene 8 and a streptavidin-biotin test 9, we demonstrate areal mass sensitivity at a level of femto-grams per mm2 and detection of individual biomolecules, respectively. Our proof-of-concept results offer a way towards simple and scalable single-molecular label-free biosensing technologies.

The Influence of the Binder Type & Aggregate Nature on the Electrical Resistivity and Compressive Strength of Conventional Concrete

description: Concrete has been used in a number of civil engineering applications due to its interesting fresh, hardened, and durability-related properties. 28-day compressive strength is the most important hardened state property and is frequently used as an indicator of the material’s quality. However, early-age mechanical properties are a key factor nowadays to enhance construction planning. Several advanced techniques have been proposed to appraise concrete microstructure and quality, and among those electrical resistivity (ER) is one of the most commonly used since it is a non-destructive and low-cost technique. Although recent literature data have shown that ER may be significantly influenced by a variety of parameters such as the test setup, material porosity and moisture content, binder type/amount and presence of supplementary cementing materials (SCMs) along with the nature of the aggregates used in the mix, further research must be performed to clarify the influence of the raw materials (i.e. SCMs and aggregate nature) on ER using distinct setups. Therefore, this work aims to appraise the influence of the coarse aggregate nature and binder replacement/amount on the concrete ER and compressive strength predictions models through ER. Twenty-four concrete mixtures were developed with two different coarse aggregate natures (i.e. granite and limestone), two different water-to-binder ratios (w/b; i.e. 0.6 and 0.4) and incorporating two different SCMs (i.e. slag and fly-ash class F) with different replacement levels. Moreover, three distinct ER techniques (e.g. bulk, surface, and internal) and compressive strength tests were performed at different ages (i.e. 3, 7, 14, and 28 days). Results indicate that the binder type and replacement amount significantly affect ER and compressive strength. Otherwise, the coarse aggregate nature presented only trivial influence for 0.6 w/b mixes, except for 50% fly-ash replacement samples; whereas for concrete specimens with enhanced microstructure (i.e. 0.4 w/b), the aggregate nature influence was statically significant especially for the binary mixtures with high SCMs replacement levels (i.e. 70% GGBS and 50% fly-ash). Finally, all ER test setups were considered to be quite suitable and reliable NDT techniques correlating themselves very well. Yet the internal resistivity setup demonstrated to be the device which yields the lowest variability amongst them.

La tradition de ces documents, qui débute au XIIe siècle et prend rapidement de l’ampleur au XIIIe siècle, présente des caractéristiques très hétérogènes, mais presque toutes les chartes sont complètement dépourvues de symboles au sens diplomatique du terme. Néanmoins, certaines d’entre elles sont structurées de telle manière que leur présentation laisse supposer un contenu symbolique. La communication se consacrera donc, sur la base d’exemples concrets du XIIe et XIIIe siècles, à la question de discuter quels critères peuvent indiquer une conception symbolique des documents concernés et quelles intentions celle-ci pourrait refléter.

description: Chen Xi is an artist born in Beijing, who has spent part of her life in Italy and currently lives in the UK. She is the author of a novel about the life of a Chinese girl in Italy and a collection of postmodern fairy tales. As both a writer and an illustrator, she uses mixed media (mostly literature and visual art, but also performance and music) to convey her creative expression. Since her style draws upon different cultural traditions to shape original, fluid meanings, she can be described as a transcultural artist and writer. This section first provides an introduction to the artist’s life, works and style, then it offers the original Italian translation of four chapters from her novel and an excerpt from an illustrated story. An interview with the author closes the section.

description: This study investigates flood avalanches in a dense reservoir network in the semiarid north-eastern Brazil. The population living in this area strongly depends on the availability of the water from this network. Water is stored during intense wet-season rainfall events and evaporates from the reservoir surface during the dry season. These seasonal changes are the driving forces behind the water dynamics in the network. The reservoir network and its connectivity properties during flood avalanches are investigated with a model called ResNetM, which simulates each reservoir explicitly. It runs on the basis of daily calculated water balances for each reservoir. A spilling reservoir contributes with water to the reservoir downstream, which can trigger avalanches affecting, in some cases, large fractions of the network. The main focus is on the study of the relation between the total amount of water stored and the largest observable cluster of connected reservoirs that overspill in the same day. It is shown that the thousands of small and middle-sized reservoirs are eminent for the retention of water upstream the large ones. Therefore, they prevent large clusters at a low level of water. Concerning connectivity measures, the actual reservoir network, which evolved without an integrated plan, performed better (i.e., generated smaller avalanches for similar amount of stored water) than numerous stochastically generated artificial reservoir networks on the same river network.

description: We propose a scheme based on topological insulators to generate Kramers pairs of Majorana fermions or parafermions in the complete absence of magnetic fields. Our setup consists of two topological insulators whose edge states are brought close to an s-wave superconductor. The resulting proximity effect leads to an interplay between a non-local crossed Andreev pairing, which is dominant in the strong electron-electron interaction regime, and usual superconducting pairing, which is dominant at large separation between the two topological insulator edges. As a result, there are zero-energy bound states localized at interfaces between spatial regions dominated by the two different types of pairing. Due to the preserved time-reversal symmetry, the bound states come in Kramers pairs. If the topological insulators carry fractional edge states, the zero-energy bound states are parafermions, otherwise, they are Majorana fermions.

description: Using the model system of ferroelectric domain walls, we explore the effects of long-range dipolar interactions and periodic ordering on the behavior of pinned elastic interfaces. In piezoresponse force microscopy studies of the characteristic roughening of intrinsic 71° stripe domains in BiFeO$_3$ thin films, we find unexpectedly high values of the roughness exponent ζ = 0.74 $\pm$ 0.10, significantly different from those obtained for artificially written domain walls in this and other ferroelectric materials. The large value of the exponent suggests that a random field-dominated pinning, combined with stronger disorder and strain effects due to the step-bunching morphology of the samples, could be the dominant source of pinning in the system.

description: Background: Globally, Medical recording service is a component of all health care system, as it is the entry point of the health service and one of the key areas to have quality service in the health facilities. Clinical record documentation is one of the most basic professional responsibilities even if it is often poorly practiced. Record keeping and information management are the requirement for the provision of quality patient service. They are essential for the patient’s present and future healthcare decision making. The information contained in the record is essential, but the process of documenting it is often considered a lesser priority by many health institutions.

Objective: The overall objective of the project is to improve completeness of inpatient medical records from 65 % to 90% in Amdework primary hospital by the end of June,30, 2019.

description: Solid inflation can support a long period of anisotropic inflation. We calculate the statistical anisotropies in the scalar and tensor power spectra and their cross-correlation in anisotropic solid inflation. The tensor-scalar cross-correlation can either be positive or negative, which impacts the statistical anisotropies of the TT and TB spectra in CMB map more significantly compared with the tensor self-correlation. The tensor power spectrum contains potentially comparable contributions from quadrupole and octopole angular patterns, which is different from the power spectra of scalar, the cross-correlation or the scalar bispectrum, where the quadrupole type statistical anisotropy dominates over octopole.

description: Germanium is the base element in many phase-change materials, i.e. systems that can undergo reversible transformations between their crystalline and amorphous phases. They are widely used in current digital electronics and hold great promise for the next generation of non-volatile memory devices. However, the ultra fast phase transformations required for these applications can be exceedingly complex even for single component systems, and a full physical understanding of these phenomena is still lacking. In this paper we study nucleation and growth of crystalline Ge from amorphous thin films at high temperature using phase field models informed by atomistic calculations of fundamental material properties. The atomistic calculations capture the full anisotropy of the Ge crystal lattice, which results in orientation dependences for interfacial energies and mobilities. These orientation relations are then exactly recovered by the phase field model at finite thickness via a novel parametrization strategy based on invariance solutions of the Allen-Cahn equations. By means of this multiscale approach, we study the interplay between nucleation and growth and find that the relation between the mean radius of the crystallized Ge grains and the nucleation rate follows simple Avrami-type scaling laws. We argue that these can be used to cover a wide region of the nucleation rate space, hence facilitating comparison with experiments.

In particular, the characters of programmed art, described by Umberto Eco in two important contributions of the early Sixties, show a connection with the theoretical reflection of Totino and the composition of the first “verbotectures”, in relation to the concepts of seriality and variation. This is evident in works like Space and Time and in the “chromophoneme” In sleep, the dream, of which a textual analysis is carried out.

Evolution or Revolution? PIDs for PID Users

description: The case for using PIDs extensively and consistently has more or less been made which begs the question as to why they are not implemented as completely as one might wish?

 The ARDC, through our National Information Infrastructure program, promotes the use of PID’s in the Australian research sector as a mechanism to link research concepts, funding, outputs, people, organisations, instruments, and objects; thereby creating a richer, more reliable, more coherent, more reproducible, and more reusable research environment.

 Through this program the ARDC provides, supports and connects with several persistent identifier services including DOI, IGSN, Handle, ORCID and PURL.

 In addition, the ARDC provides actual infrastructure and project funding and support so we are ourselves deeply interested in both the ability of PID’s to enable new and better research as well as how they can be used to reflect the impact of our activities. The question “how is the world better because it invested resources in the ARDC?” is key. The Research Activity Identifier (RAiD) was created to answer this question, being a model which links activities, inputs and outputs in the research lifecycle.

 For ARDC to rely on PID’s we need to assume the identifier infrastructure itself is persistent and sustainable.

 So, as an infrastructure operator with a particular set of drivers and desired outcomes from the use of PID's we’d like to ask some questions around whether harmonisation (and consolidation?) of PID’s and PID providers might facilitate sustainability (it’s perhaps easier to fund a PID provider who does it all?) and implementation (would it be easier to implement and use PIDs if they followed the same minting, usage, and governance models?).

 Think of this as a devil’s advocate session, I’d love to understand if there are reasons why harmonisation and consolidation are not sensible next steps now that the use case for PID’s (but PID’s in total rather than as individuals) has more or less been made.

 How would you run the session to support the spirit of PIDapalooza as a laid-back, welcoming, energetic and exciting meeting, and ensure at least 10 minutes of your session are used to interact with the audience?

 Ideally this session would be largely audience interaction. The questions to be posed range from the peripheral (“how might PID organisations share good practice?”) to fundamental (“Why, now that PID’s have been shown to be critical, would I not just set up an international PID organisation with my other government colleagues and standardise it all?”)

 That second question might be a bit much, but you did ask for energetic and exciting!

description: This introductory essay aims to shed light on the theoretical raison d’être, the intersections within, and the main lines shared by the five essays that make up this section. The section is dedicated to transnational and blended learning spaces in telecollaborative, trans-institutional projects. This piece pivots on the increasingly important and pervasive theoretical notion of the “Spatial Turn” (Bachmann-Medick 2016, 211-243), which has become increasingly visible in, among other fields, pedagogy and cultural studies, and more specifically in the idea of boundary-crossing and hybridisation not only of physical but also of methodological spaces. This introductory essay shows how these five scholarly pieces contribute in different ways to enriching the interdisciplinary scholarly space at the intersection of intercultural awareness and technology- enhanced teaching and learning of foreign languages and cultures.

description: In this letter we report the singlet ground state structure of the full carotenoid peridinin by means of variational Monte Carlo (VMC) calculations. The VMC relaxed geometry has an average bond length alternation of 0.1165(10) Å, larger than the values obtained by DFT (PBE, B3LYP and CAM-B3LYP) and shorter than that calculated at the Hartree-Fock (HF) level. TDDFT and EOM-CCSD calculations on a reduced peridinin model confirm the HOMO-LUMO major contribution of the Bu+-like (S2) bright excited state. Many Body Green's Function Theory (MBGFT) calculations of the vertical excitation energy of the Bu+-like state for the VMC structure (VMC/MBGFT) provide excitation energy of 2.62 eV, in agreement with experimental results in n-hexane (2.72 eV). The dependence of the excitation energy on the bond length alternation in the MBGFT and TDDFT calculations with different functionals is discussed.

description: The study was aimed to produce cheddar and cottage cheese from doe and ewe milk. The sources of milk were from Arsi Negele and Kofele areas of Oromiya region. Cheddar cheeses were made from whole doe, whole ewe milk and their mixtures contained ratio of 25, 50 and 75% of doe and ewe milk using standard procedure for cheddar cheese processing technology. The proximate, microbiological, Physico-chemical, sensory analysis and yield calculation of the cheeses were made at chemical Engineering laboratory, Holleta agricultural research center, Ethiopian health and nutrition research institute.The proximate analysis result showed that cheeses made from 100% doe milk had the lowest moisture content (27.77%) and highest fat content (54.80%) but a lower yield (0.66kg/5kg of whole milk) compared to cheeses made from 100% ewe milk (35.29%, 30.1%, 0.88kg/5kg of whole milk respectively). Other mix ratios had intermediate values between the two specious of cheese (p<0.05). No significant differences in the values of protein, total solid and lactose content of sampled cheeses were found. Microbiological results showed that all cheeses made were within the limit range for acceptable conditions for consumers (< 1* 104 cfu/g).

description: This paper studies the secure beamforming design in a multiple-antenna three-node system where two source nodes exchange messages with the help of an untrusted relay node. The relay acts as both an essential signal forwarder and a potential eavesdropper. Both two-phase and three-phase two-way relay strategies are considered. Our goal is to jointly optimize the source and relay beamformers for maximizing the secrecy sum rate of the two-way communications. We first derive the optimal relay beamformer structures. Then, iterative algorithms are proposed to find source and relay beamformers jointly based on alternating optimization. Furthermore, we conduct asymptotic analysis on the maximum secrecy sum-rate. Our analysis shows that when all transmit powers approach infinity, the two-phase two-way relay scheme achieves the maximum secrecy sum rate if the source beamformers are designed such that the received signals at the relay align in the same direction. This reveals an important advantage of signal alignment technique in against eavesdropping. It is also shown that if the source powers approach zero the three-phase scheme performs the best while the two-phase scheme is even worse than direct transmission. Simulation results have verified the efficiency of the secure beamforming algorithms as well as the analytical findings.

description: In the fragmented air cargo industry, the traditional peer-to-peer air cargo messaging for communication has the limitations of lack of transparency in the end-to-end supply chain and complex digital connectivity. With the blockchain characteristics of decentralisation and immutability ensuring data transparency and security, our work proposes to apply blockchain technology for air cargo messaging to streamline the multi-stage communication flow among stakeholders using smart contracts and to act as an intermediary to simplify the digital connections among air cargo stakeholders. Technical performance, cost benefit and adoption challenges are investigated for the feasibility of adopting the blockchain system in the industry.

description: The authoritativeness of a charter - as defined in the terms which, mutatis mutandis, are so familiar to us: a written document of legal characters, which follows certain standards in its inner and outer characteristics - this chancery style forces charters into a tight corset.

Formulary (especially the cursus) and form, the fonts used for the various sections of the charter, guidelines regarding means of authentication, all of these, depending on the degree of differentiation in materials, techniques, and other features (elongated scripts, highlighted scripts, monogram, subscription sign (beehive), littera cum spatiis et floribus, cum filo serico, cum filo canabis, rota, to mention just a few) are regulated according to a notion of ‘correctness’. These have provided the tools of the trade for the development of “diplomatics'' as a science (Mabillon, Bessler, Gatterer, …).

Since these criteria are, as a rule, known to both issuer and recipient, they were utilised as criteria of authenticity for validation already in the Middle Ages, and later on for confirmation (“collationiert und auscultiert”).

All of this is taught in the milieu of the chancery and the scribes, the formulary particularly in the artes dictandi. This went so far that students were trained not only regarding the proper addresses of recipients and the intitulationes of issuers for their particular social environment, but even provided models and patterns (or outlines for such) for the intended document.

Where, in all this, is there room for individuals and individual expression?

Important decisions are generally supported through the naming of witnesses; if those witnesses do not sign the document personally, we are dealing with a special notion of credibility.

Late mediaeval election confirmations - the examples are chosen from a Benedictine context - lead us into specific written landscapes. Witnesses (members of a convent) sign on the same day. The formulary appears to have been rendered identically. The documents give insight into fluency and individuality of some, just as much as others consciously imitate the script of the ‘predecessor’. Yet others have to clumsily draw out the letters, as they have no practice in writing.

We find old writings and old forms next to “modern” forms; confidence next to modesty? But expertise also leads to falsification and forgery.

description: We present new model of D=4 relativistic massive particle with spin and we describe its quantization. The model is obtained by an extension of standard relativistic phase space description of massive spinless particle by adding new topological Souriau-Wess-Zumino term which depends on spin fourvector variable. We describe equivalently our model as given by the free two-twistor action with suitable constraints. An important tool in our derivation is the spin-dependent twistor shift, which modifies standard Penrose incidence relations. The quantization of the model provides the wave function with correct mass and spin eigenvalues.

description: We investigate the vacuum polarization and the Casimir energy of a Dirac field coupled to a scalar potential in one spatial dimension. Both of these effects have a common cause which is the distortion of the spectrum due to the coupling with the background field. Choosing the potential to be a symmetrical square-well, the problem becomes exactly solvable and we can find the whole spectrum of the system, analytically. We show that the total number of states and the total density remain unchanged as compared with the free case, as one expects. Furthermore, since the positive- and negative-energy eigenstates of the fermion are fermion-number conjugates of each other and there is no zero-energy bound state, the total density and the total number of negative and positive states remain unchanged, separately. Therefore, the vacuum polarization in this model is zero for any choice of the parameters of the potential. It is important to note that although the vacuum polarization is zero due to the symmetries of the model, the Casimir energy of the system is not zero in general. In the graph of the Casimir energy as a function of the depth of the well there is a maximum approximately when the bound energy levels change direction and move back towards their continuum of origin. The Casimir energy for a fixed value of the depth is a linear function of the width and is always positive. Moreover, the Casimir energy density (the energy density of all the negative-energy states) and the energy density of all the positive-energy states are exactly the mirror images of each other. Finally, computing the total energy of a valence fermion present in the lowest fermionic bound state, taking into account the Casimir energy, we find that the lowest bound state is almost always unstable for the scalar potential.

description: Heavy-flavour hadrons, i. e. hadrons carrying charm or beauty quarks, are a well-suited probe to study the Quark-Gluon Plasma (QGP) in relativistic heavy-ion collisions. For this reason, measurements of electrons from heavy-flavour hadron decays have been performed in pp, p-Pb and Pb-Pb collisions at the LHC with the ALICE detector. Results for the nuclear modification factors ($R_{\rm{pA}}$ and $R_{\rm{AA}}$) support a final-state energy loss of heavy quarks in central Pb-Pb collisions and, in semi-central collisions a positive elliptic flow coefficient $v_{2}$ of electrons from heavy-flavour hadron decays was observed. Furthermore, a double-ridge structure was observed in the measured two-particle angular correlation distribution, triggered by heavy-flavour decay electrons, in high-multiplicity p-Pb collisions relative to low-multiplicity p-Pb collisions and to pp collisions.

description: Raman sensing and Raman microscopy are amongst the most specific optical technologies to identify the chemical compounds of unknown samples, and to enable label-free biomedical imaging with molecular contrast. However, the high cost and complexity, low speed, and incomplete spectral information provided by current technology are major challenges preventing more widespread application of Raman systems. To overcome these limitations, we developed a new method for stimulated Raman spectroscopy and Raman imaging using continuous wave (CW), rapidly wavelength swept lasers. Our all-fiber, time-encoded Raman (TICO-Raman) setup uses a Fourier Domain Mode Locked (FDML) laser source to achieve a unique combination of high speed, broad spectral coverage (750 cm-1 - 3150 cm-1) and high resolution (0.5 cm-1). The Raman information is directly encoded and acquired in time. We demonstrate quantitative chemical analysis of a solvent mixture and hyperspectral Raman microscopy with molecular contrast of plant cells.

description: Rotheca serrata (L.) Steane & Mabb. a plant having significant medicinal value is used in treating a fever, rheumatism, inflammation, pain, and malarial fever. Ursolic acid has a five-ringed pentacyclic structure belongs to the family of triterpenoids. It has antioxidant, antitumor, and hepato-protective properties. The method in HPLC was developed on a SHIMADZU, Shimpack ODS (25 cm × 4.6 mm, 5 µm) column. The mobile phase consisted of a 70:25:5 (v/v/v) mixture of methanol, acetonitrile, and 0.02 M ammonium acetate buffer (pH 3.5). A flow rate of 1.2 mL/min and λmax of 215 nm. Ursolic acid from the extract and standard was eluted at the same retention time of 4.1 min. 20–120 µg/mL was the linearity range chosen and was found to be linear (R2=0.996). The value of LOD was 0.85 µg/mL and LOQ was 1.96 µg/mL. The method for analysis of ursolic was found to be accurate with good repeatability.

description: The interview covers Price’s turn to international projects after he stepped down as dean of the Benjamin N. Cardozo School of Law in 1991. Price describes his travel, scholarly projects, and relationships to research centers in Central Europe, the Balkans, Russia, India, and elsewhere, in the 1990s and early 2000s. The establishment of the Oxford Programme in Comparative Media Law and Policy in the mid-1990s is discussed. Price recounts his close collaborations with Andrei Richter, Peter Krug, and Stefaan Verhulst. He describes projects for the US Agency for International Development (USAID), the Carter Center’s Commission on Radio and Television Policy, and the Markle Foundation. Price’s concept of the “market for loyalties” is discussed, in relationship to freedom of expression, media technologies, and sovereignty, and in relationship to a pair of single-authored book—Television, the Public Sphere, and National Identity (1996), Media and Sovereignty (2002)—and a number of edited volumes.

description: Scalar \cite{scalar_paper} and tensor \cite{tensor_paper} glueballs created in $J/ψ$ radiative decays are studied in quenched lattice QCD. Using two anisotropic lattices to approach the continuum limit, we compute the relevant form factors responsible for the decay rates for $J/ψ\rightarrowγG_{0^{++}}$ and $J/ψ\rightarrowγG_{2^{++}}$. Comparing with the existing experimental data, it is argued that $f_0(1710)$ is a favorable candidate for scalar glueball. The decay rate for $J/ψ\rightarrowγG_{2^{++}}$ is found to be quite substantial. A comprehensive search in the tensor channel on BESIII is therefore suggested.

description: The present work investigated the anxiolytic effect of the alkaloid fraction (AF II) from the root bark of Mimosa tenuiflora. Female Swiss mice of 6 weeks old were used in this study. The animals were divided into three groups: 0.9% NaCl (vehicle group, s.c.), AF II (6 mg/kg, s.c.), and diazepam – DZP (5 mg/kg, s.c.). The light/dark box and elevated plus maze tests evaluated the animal anxiety. DMT was identified by the HPLC method. AF II showed significant anxiolytic effects in the two behavioural tests used.
