Effect of lactoferrin digest and ozone treatments on Penicillium spp. isolated from bottled water
Creators: name: Liceaga Gesualdo, Andrea
Publisher: name: University of British Columbia
Year: 2009

description: Recently, consumers have complained about visible fungi contamination in bottled water; this has caused the industry a series of rejected products. These fungi seem to be resistant to the common sterilization processes, such as ozonation, used for bottled water. In this study, the main objective was to investigate the effect of an antimicrobial peptide and ozone treatments on a Penicillium spp. isolated from bottled water. Foreign bodies were isolated from bottled water and plated on potato dextrose agar. A loopfull from a visible colony was examined by phase contrast microscope for identification based on its morphology. Fungi isolated from the bottled water were identified as Penicillium sp. using three specialized media. A stock suspension was obtained by washing the spores after 7 days incubation at 25°C on PDA. Lactoferrin (5% w/v), isolated from cheese whey, was digested at 37°C for 4 hrs using porcine pepsin (3% w/w) at pH 2.3. Digestion was terminated by increasing the temperature to 80°C for 15 min and the pH to 7.0. The digest was centrifuged and the supernatant filtered through a 0.45 μ cellulose acetate filter. Digestion was confirmed by SDS-PAGE electrophoresis. Lactoferrin digest (LFD), containing lactoferricin, was used without further purification. The antimicrobial assay was performed using a 96 well microplate containing peptone yeast glucose medium (PYG) and known concentrations of LFD. Each well was inoculated with the spore suspension (7xl0³ mL⁻¹ spores); bovine serum albumin digest was used as negative control. Culture optical density was monitored at 595 nm over time. LFD at concentrations of 0.06 and 0.3 mg/mL inhibited spore germination and mycelial fusion for up to 9 and 21 days at 30°C, respectively. Ozonation experiments were carried out at 0.1-0.4 ppm ozone in 100 mL of distilled deionized water with or without LFD (0.03, 0.06 0.30 mg/mL). Two experimental set ups were used; one consisted of adding ozonated water (65 mL) to 35 mL of spore suspension (3xl0⁶ mL⁻¹ spores). Samples (1 mL) of ozonated spores were retrieved at 0, 4, 8 and 12 min and plated on potato dextrose trypan blue agar using the hydrophobic grid membrane filtration (HGMF) method. The second set up consisted of directly ozonating 100 mL inoculated water (0.9 mL spore suspension with 99.1 mL d-d water). Samples (1 mL) were retrieved every 30 seconds for a period of 3 minutes and plated as described above. Ozone concentrations in the range of 0.1-0.4 ppm stimulated spore germination, mycelial fusion and growth. LFD when added, led to slower development of mould colonies on the HGMF filters.

description: We specify an experts algorithm with the following characteristics: (a) it uses only feedback from the actions actually chosen (bandit setup), (b) it can be applied with countably infinite expert classes, and (c) it copes with losses that may grow in time appropriately slowly. We prove loss bounds against an adaptive adversary. From this, we obtain master algorithms for "active experts problems", which means that the master's actions may influence the behavior of the adversary. Our algorithm can significantly outperform standard experts algorithms on such problems. Finally, we combine it with a universal expert class. This results in a (computationally infeasible) universal master algorithm which performs - in a certain sense - almost as well as any computable strategy, for any online problem.

description: Nonlinear spintronics, which combines nonlinear dynamics and spintronics, opens a new route for controlling spins and spin dynamics beyond conventional spintronics based on linear responses. Strongly correlated electron systems, which can have large nonlinear responses, are promising candidates for nonlinear spintronics. In this paper, we focus on the nonlinear Edelstein effect (NEE), a generalization of the Edelstein effect, and study the impact of electron correlations on the NEE by performing numerical calculations on a Hubbard model. We find that correlation effects can either enhance or suppress the nonlinear response. We show that the enhancement and suppression of the response are due to the real and imaginary components of the self-energy, respectively. Additionally, we have explored the relationship between the NEE and photomagnetic or optomagnetic effects. Our findings demonstrate that electron correlations can either enhance or suppress the optical spin injection, depending on the light frequency, while always strengthening the inverse Faraday effect.

description: We study the dynamical behaviour of ultracold fermionic atoms loaded into an optical lattice under the presence of an effective magnetic flux, induced by spin-orbit coupled laser driving. At half filling, the resulting system can emulate a variety of iconic spin-1/2 models such as an Ising model, an XY model, a generic XXZ model with arbitrary anisotropy, or a collective one-axis twisting model. The validity of these different spin models is examined across the parameter space of flux and driving strength. In addition, there is a parameter regime where the system exhibits chiral, persistent features in the long-time dynamics. We explore these properties and discuss the role played by the system's symmetries. We also discuss experimentally-viable implementations.

Subjects: Livestock Production/Industries

description: Partial equilibrium analysis is used to estimate the social costs of production control in the Australian egg industry. These costs are compared with the estimates of the social cost of the home consumption price scheme which has operated in the past. The comparison is made for various supply and demand conditions and for alternative pricing and quota policies. The method used is to model historical supply and demand relationships for the years 1965-6 to 1972-3. Actual price and quantity data for these years is then used to estimate the social cost of home consumption pricing as it operated in that period. Simulated production controls are imposed on the model and the resulting social costs and benefits are estimated.

description: Task offloading, crucial for balancing computational loads across devices in networks such as the Internet of Things, poses significant optimization challenges, including minimizing latency and energy usage under strict communication and storage constraints. While traditional optimization falls short in scalability; and heuristic approaches lack in achieving optimal outcomes, Reinforcement Learning (RL) offers a promising avenue by enabling the learning of optimal offloading strategies through iterative interactions. However, the efficacy of RL hinges on access to rich datasets and custom-tailored, realistic training environments. To address this, we introduce PeersimGym, an open-source, customizable simulation environment tailored for developing and optimizing task offloading strategies within computational networks. PeersimGym supports a wide range of network topologies and computational constraints and integrates a \textit{PettingZoo}-based interface for RL agent deployment in both solo and multi-agent setups. Furthermore, we demonstrate the utility of the environment through experiments with Deep Reinforcement Learning agents, showcasing the potential of RL-based approaches to significantly enhance offloading strategies in distributed computing settings. PeersimGym thus bridges the gap between theoretical RL models and their practical applications, paving the way for advancements in efficient task offloading methodologies.

description: The reconstruction theorem is a cornerstone of the theory of regularity structures [Hai14]. In [CZ20] the authors formulate and prove this result in the language of distributions theory on the Euclidean space $\mathbb{R}^d$, without any reference to the original framework. In this paper we generalize their constructions to the case of distributions over a generic $d$-dimensional smooth manifold $M$, proving the reconstruction theorem in this setting. This is done having in mind the extension of the theory of regularity structures to smooth manifolds.

description: We introduce a toy model that allows us to study the physical properties of a spin impurity coupled to the electrons in the superconducting island. We show that when the coupling of the spin is of the order of the superconducting gap two almost degenerate subgap states are formed. By computing the Berry phase that is associated with the superconducting phase rotations in this model, we prove that these subgap states are characterized by a different charge and demonstrate that the switching between these states has the same effect as quasiparticle poisoning (unpoisoning) of the island. We also show that an impurity coupled to both the island and the lead generates Josepshon current fluctuations.

description: The problem investigated is how to estimate expected profits and the risk of using nitrogenous fertilizer for purposes of making fertilizer recommendations and explaining farmer decisions. Three inappropriate methods are discussed and a new method is developed which combines experimentally determined production functions with cross-section data on crop damages. For the Philippine situation analyzed, it appears that using the amount of nitrogen fertilizer which maximizes expected profits does not substantially increase the risk above low nitrogen levels. This finding casts doubt on the hypothesis that farmers' reluctance to use modern techniques is due to their aversion to risk.

description: Localization of molecular orbitals finds its importance in the representation of chemical bonding (and anti-bonding) and in the local correlation treatments beyond mean-field approximation. In this paper, we generalize the intrinsic atomic and bonding orbitals [G. Knizia, J. Chem. Theory Comput. 2013, 9, 11, 4834-4843] to relativistic applications using complex and quaternion spinors, as well as to molecular fragments instead of atomic fragments only. By performing a singular value decomposition, we show how localized valence virtual orbitals can be expressed in this intrinsic minimal basis. We demonstrate our method on systems of increasing complexity, starting from simple cases such as benzene, acrylic-acid and ferrocene molecules, and then demonstrating the use of molecular fragments and inclusion of relativistic effects for complexes containing heavy elements such as tellurium, iridium and astatine. The aforementioned scheme is implemented into a standalone program interfaced with several different quantum chemistry packages.

description: We use a rigid axisymetric microfluidic flow focusing device to produce monodisperse bubbles, dispersed in a surfactant solution. The gas volume fraction of the dispersion collected out of this device can be as large as 90%, demonstrating that foam with solid-like viscoelastic properties can be produced in this way. The polydispersity of the bubbles is so low that we observe crystallization of our foam. We measure the diameter of the bubbles and compare these data to recent theoretical predictions. The good control over bubble size and foam gas volume fraction shows that our device is a flexible and promising tool to produce calibrated foam at a high flow rate.

description: We derive the effective Hamiltonian describing collective oscillations of Majorana neutrinos with a transition magnetic moment, allowing for the presence of scalar and pseudoscalar nonstandard neutrino self-interactions (NSSIs). Using this Hamiltonian, we analyze new flavor instability channels of collective oscillations in a core-collapse supernova environment that open up in the presence of a small but nonzero neutrino magnetic moment. It turns out that, contrary to certain claims in the literature, within the minimally extended Standard Model (i.e., without NSSIs), no new instabilities arise within the linear order, nor do they produce any observable signatures in the neutrino flavor-energy spectra, at least for magnetic moments up to $10^{-15}~μ_{\text{B}}$ and quite realistic fields of the order of $10^{12}~$Gauss. On the other hand, in the presence of NSSIs, new fast and slow instabilities mixing neutrinos and antineutrinos appear, which show up in the spectra even for tiny magnetic moments of the order of $10^{-24}~μ_{\text{B}}$, leading to considerable distortions of the spectra and nonstandard spectral splits. We study sensitivity of collective oscillations to these, NSSI-induced instabilities in detail and discuss the observability of the NSSI couplings triggering them.

description: We undertook a time-series photometric multi-site campaign for the rapidly oscillating Ap star HD 99563 and also acquired mean light observations over two seasons. The pulsations of the star, that show flatter light maxima than minima, can be described with a frequency quintuplet centred on 1557.653 microHertz and some first harmonics of these. The amplitude of the pulsation is modulated with the rotation period of the star that we determine with 2.91179 +/- 0.00007 d from the analysis of the stellar pulsation spectrum and of the mean light data. We break the distorted oscillation mode up into its pure spherical harmonic components and find it is dominated by the l=1 pulsation, and also has a notable l=3 contribution, with weak l=0 and 2 components. The geometrical configuration of the star allows one to see both pulsation poles for about the same amount of time; HD 99563 is only the fourth roAp star for which both pulsation poles are seen and only the third where the distortion of the pulsation modes was modelled. We point out that HD 99563 is very similar to the well-studied roAp star HR 3831. Finally, we note that the visual companion of HD 99563 is located in the Delta Scuti instability strip and may thus show pulsation. We show that if the companion was physical, the roAp star would be a 2.03 solar mass object, seen at a rotational inclination of 44 degrees, which then predicts a magnetic obliquity of 86.4 degrees.

description: This paper is concerned with determining the nature of and the relationships between movements in a number of New South Wales pig and pork price series. Spectral and cross-spectral methods are applied to some ten series differentiated by type of pig and market level. Results indicate that over the long term there are in general strong correlations between the various price pairings examined, but that in the shorter-run, price changes are not well reflected throughout the pig market. The role of imperfect information is noted as a major contributor to this observed short-run price independence.

description: Over the past few decades, extensive research has been devoted to the design of artificial reverberation algorithms aimed at emulating the room acoustics of physical environments. Despite significant advancements, automatic parameter tuning of delay-network models remains an open challenge. We introduce a novel method for finding the parameters of a Feedback Delay Network (FDN) such that its output renders target attributes of a measured room impulse response. The proposed approach involves the implementation of a differentiable FDN with trainable delay lines, which, for the first time, allows us to simultaneously learn each and every delay-network parameter via backpropagation. The iterative optimization process seeks to minimize a perceptually-motivated time-domain loss function incorporating differentiable terms accounting for energy decay and echo density. Through experimental validation, we show that the proposed method yields time-invariant frequency-independent FDNs capable of closely matching the desired acoustical characteristics, and outperforms existing methods based on genetic algorithms and analytical FDN design.
New constraints on the planetary system around the young active star AU Mic. Two transiting warm Neptunes near mean-motion resonance

description: AU Mic is a young, active star whose transiting planet was recently detected. We report our analysis of its TESS data, where we modeled the BY Draconis type quasi-periodic rotational modulation by starspots simultaneously to the flaring activity and planetary transits. We measured a flare occurrence rate of 6.35 flares per day for flares with amplitudes in the range of $0.06\% < f_{\rm max} < 1.5\%$ of the star flux. We employed a Bayesian MCMC analysis to model the five transits of AU Mic b, improving the constraints on the planetary parameters. The planet radius of $4.07\pm0.17$~R$_{\oplus}$ and a mean density of $1.4\pm0.4$~g~cm$^{-3}$ confirms that it is a Neptune-size moderately inflated planet. While a single feature possibly due to a second planet was previously reported in the former TESS data, we report the detection of two additional transit-like events in the new TESS observations of July 2020. This represents substantial evidence for a second planet (AU Mic c) in the system. We analyzed its three transits and obtained an orbital period of $18.859019\pm0.000016$~d and a planetary radius of $3.24\pm0.16$~R$_{\oplus}$, which defines it as a warm Neptune-size planet with an expected mass in the range of 2.2~M$_{\oplus}$~$< M_{\rm c} < $25.0~M$_{\oplus}$. The two planets in the system are in near 9:4 mean-motion resonance. We show that this configuration is dynamically stable and should produce transit-timing variations (TTV). Our non-detection of significant TTV in AU Mic b suggests an upper limit for the mass of AU Mic c of $<7$~M$_{\oplus}$, indicating that this planet is also likely to be inflated. As a young multi-planet system with at least two transiting planets, AU Mic becomes a key system for the study of atmospheres of infant planets and of planet-planet and planet-disk dynamics at the early stages of planetary evolution.

description: We introduce a dynamic stabilization scheme universally applicable to unidirectional nonlinear coherent waves. By abruptly changing the waveguiding properties, the breathing of wave packets subject to modulation instability can be stabilized as a result of the abrupt expansion a homoclinic orbit and its fall into an elliptic fixed point (center). We apply this concept to the nonlinear Schrödinger equation framework and show that an Akhmediev breather envelope, which is at the core of Fermi-Pasta-Ulam-Tsingou recurrence and extreme wave events, can be frozen into a steady periodic (dnoidal) wave by a suitable variation of a single external physical parameter. We experimentally demonstrate this general approach in the particular case of surface gravity water waves propagating in a wave flume with an abrupt bathymetry change. Our results highlight the influence of topography and waveguide properties on the lifetime of nonlinear waves and confirm the possibility to control them.

description: In the presence of a conserved quantity, symmetry-resolved entanglement entropies are a refinement of the usual notion of entanglement entropy of a subsystem. For critical 1d quantum systems, it was recently shown in various contexts that these quantities generally obey entropy equipartition in the scaling limit, i.e. they become independent of the symmetry sector. In this paper, we examine the finite-size corrections to the entropy equipartition phenomenon, and show that the nature of the symmetry group plays a crucial role. In the case of a discrete symmetry group, the corrections decay algebraically with system size, with exponents related to the operators' scaling dimensions. In contrast, in the case of a U(1) symmetry group, the corrections only decay logarithmically with system size, with model-dependent prefactors. We show that the determination of these prefactors boils down to the computation of twisted overlaps.

description: New product development (NPD) is a knowledge intensive process where the generation of new ideas and concepts requires detailed knowledge of both products and customers. The high reported failure rates for innovative functional beverages suggest an inability to manage customer knowledge effectively, as well as a lack of knowledge management between functional disciplines involved in the NPD process. This research explored the concept of managing customer knowledge at the early stages of the NPD process, through the use of advanced concept optimisation methods, and applied it to the development of a range of functional beverages. A conjoint - based survey was administered to four hundred customers in Ireland. This research identified two hypothetical functional beverage concepts with high levels of customer acceptance. Managing customer knowledge during the concept development stage of the NPD process can assist firms overcome customer acceptance issues associated with innovative products. Methodologies that advance both a firm's understanding of customers' choice motives and value systems, and its knowledge management process, can increase the chances of new product success in international food and beverage markets.

description: e present wide field deep UBVI photometry for the previously unstudied open cluster NGC 4852 down to a limiting magnitude $I\sim24$, obtained from observations taken with the Wide Field Imager camera on-board the MPG/ESO 2.2m telescope at La Silla (ESO, Chile). These data are used to obtain the first estimate of the cluster basic parameters, to study the cluster spatial extension by means of star counts, and to derive the Luminosity (LF) and Mass Function (MF). The cluster radius turns out to be $5.0\pm1.0$ arcmin. The cluster emerges clearly from the field down to V=20 mag. At fainter magnitud es, it is completely confused with the general Galactic disk field. The stars inside this region define a young open cluster (200 million years old) 1.1 kpc far from the Sun (m-M = 11.60, E(B-V) = 0.45). The Present Day Mass Functions (PDMF) from the $V$ photometry is one of the most extended in mass insofar obtained, and can be represented as a power-law with a slope $α= 2.3\pm0.3$ and (the Salpeter (1955) MF in this notation has a slope $α= 2.35$), in the mass range $3.2 \leq \frac{m}{m_{\odot}} \leq 0.6$. Below this mass, the MF cannot be considered as representative of the cluster MF, as the cluster merges with the field and therefore the MF is the result of the combined effect of strong irregularities in the stellar background and interaction of the cluster with the dense Galactic field. The cluster total mass at the limiting magnitude results to be 2570$\pm$210 M$_{\odot}$.

description: The circumgalactic medium (CGM) of star-forming dwarf galaxies plays a key role in regulating the galactic baryonic cycle. We investigate how susceptible the CGM of dwarf satellite galaxies is to ram pressure stripping (RPS) in Milky Way-like environments. In a suite of hydrodynamical wind tunnel simulations, we model an intermediate-mass dwarf satellite galaxy ($M_{*} = 10^{7.2}~M_{\odot}$) with a multiphase interstellar medium (ISM; $M_{\rm ISM} = 10^{7.9}~M_{\odot}$) and CGM ($M_{\rm CGM,vir} = 10^{8.5}~M_{\odot}$) along two first-infall orbits to more than 500 Myr past pericenter of a Milky Way-like host. The spatial resolution is $\sim$79 pc in the star-forming ISM and $316-632$ pc in the CGM. Our simulations show that the dwarf satellite CGM removal is fast and effective: more than $95\%$ of the CGM mass is ram-pressure-stripped within a few hundred Myrs, even under a weak ram pressure orbit where the ISM stripping is negligible. The conditions for CGM survival are consistent with the analytical halo gas stripping predictions in McCarthy et al. (2008). We also find that including the satellite CGM does not effectively shield its galaxy, and therefore the ISM stripping rate is unaffected. Our results imply that a dwarf galaxy CGM is unlikely to be detected in satellite galaxies; and that the star formation of gaseous dwarf satellites is likely devoid of replenishment from a CGM.

description: Many structural glasses feature static and dynamic mechanical properties that can depend strongly on glass formation history. The degree of universality of this history-dependence, and what it is possibly affected by, are largely unexplored. Here we show that the variability of elastic properties of simple computer glasses under thermal annealing depends strongly on the strength of attractive interactions between the glasses' constituent particles -- referred to here as glass `stickiness'. We find that in stickier glasses the stiffening of the shear modulus with thermal annealing is strongly suppressed, while the thermal-annealing-induced softening of the bulk modulus is enhanced. Our key finding is that the characteristic frequency and density per frequency of soft quasilocalized modes becomes effectively invariant to annealing in very sticky glasses, the latter are therefore deemed `thermo-mechanically inannealable'. The implications of our findings and future research directions are discussed.

description: This paper examines and analyzes the impacts of the reformed CAP as well as the decisions of the new round of negotiations for the olive oil and cotton sectors in the European Union. The aim of this study is to estimate the changes in supply (agricultural supply plus intermediate demand and final production), demand (consumption), price and stock formation (import, export, beginning and ending stocks, national price formation) for both the olive oil and cotton sectors. The model designed for this purpose is partial equilibrium and policy oriented. The objectives of this model are to estimate changes in the production and consumption of the two products concerned, to determine how the reformed Common Agricultural Policy (CAP) and the new round of negotiations of the World Trade Organization (WTO) affect these two sectors, to analyze the evolution of export and import volumes, and finally to determine how this evolution will influence the welfare situation of the olive oil and cotton sectors.

description: Η κατανόηση των τεχνολογιών των τρισδιάστατων εκτυπώσεων με αναφορά στην εξέλιξή τους και έμφαση στην εφαρμογή τους στις σύγχρονες τεχνολογίες αποτελεί τον σκοπό της εργασίας. Τα στοιχεία συγκεντρώθηκαν με βιβλιογραφική ανασκόπηση, ενώ χρησιμοποιήθηκαν και πηγές από το διαδίκτυο. Η ιδέα των 3D εκτυπωτών ξεκίνησε επίσημα με τη δημοσίευση σχετικού άρθρου του Raymond F. Jones, "Tools of the Trade", σε τεύχος του περιοδικού Astounding Science Fiction το 1950. Έπειτα από μερικά χρόνια εμφανίστηκαν οι πρώτες αιτήσεις ευρεσιτεχνίας και η εξέλιξή τους υπήρξε αλματώδης. Σήμερα υπάρχουν περισσότερες από 10 τεχνολογίες 3D εκτύπωσης. Οι προοπτικές είναι τεράστιες τόσο στην ανάπτυξη της τεχνολογίας όσο και στην εφαρμογή εξειδικευμένων προϊόντων. Υπάρχουν προοπτικές σε εξέλιξη για χρήση των εκτυπώσεων 3D στο διάστημα και σε τρόφιμα. Η υποστήριξη των τεχνολογικά εξελιγμένων βιομηχανικών μοντέλων θα πρέπει να γίνεται από κατάλληλα καταρτισμένο προσωπικό. Η 3D εκτύπωση συντελεί στην εφαρμογή της τρισδιάστατης αποτύπωσης των ιδεών των σχεδιαστών οπτικής επικοινωνίας. Η εργασία είναι δομημένη σε τρεις ενότητες. Στην πρώτη παρουσιάζονται οι τεχνολογίες των 3D εκτυπωτών, στη δεύτερη αναπτύσσεται η ιστορική τους εξέλιξη και στην τρίτη συζητείται η εφαρμογή της 3D εκτύπωσης στην οπτική επικοινωνία.

description: Foreign trade in agricultural and food products is a very important component of trade and agricultural policy. In the recent years these policies change influencing on the result of this trade and indirectly on food producers as well as consumers. The aim of this paper is look through the agri - food trade between Poland and European Union countries and the process of Poland's integration with the European Union which had an essential impact on trade between the member countries. The integration process connected with transition from a protective trade policy to a liberal trade policy was favourable for Poland. From 1989 to 2003, the volume of trade turnover in agri- food products between Poland and European Union increased over twofold. The European Union member states are main trading partners of Poland. They accounted for over half (51.6%) of the turnover in farm and food trade in 2003. The main partners on the export side are: Germany, Netherlands, Great Britain and Italy; and on the import side are Germany, Netherlands, Spain and Italy. Trade in farm and food goods with the European Union was favourable for Poland for the first time since 2003. Poland has gained trade advantages in the food sector after integration with the EU.

description: We show that the static friction force which must be overcome to render a sticking contact sliding is reduced if an external torque is also exerted. As a test system we study a planar disk lying on horizontal flat surface. We perform experiments and compare with analytical results to find that the coupling between static friction force and torque is nontrivial: It is not determined by the Coulomb friction laws alone, instead it depends on the microscopic details of friction. Hence, we conclude that the macroscopic experiment presented here reveals details about the microscopic processes lying behind friction.

description: We show that Property $\mathrm{(TTT)}$ is an obstruction to weak amenability with Cowling--Haagerup constant $1$. More precisely, if $G$ is a countable group and $H$ is an infinite subgroup of $G$ such that the pair $(G,H)$ has relative Property $\mathrm{(TTT)}$, then the weak Haagerup constant $\boldsymbolΛ_{\mathrm{WH}}(G)$ is strictly greater than $1$. We apply this result to some semidirect products and lattices in higher rank algebraic groups.

Perceptual properties, conceptual domain, and the acquisition of words for solids and nonsolids

Publisher: name: University of British Columbia

description: In 2 experiments, we taught 120 3-year-olds and 120 adults novel words for unfamiliar solid objects or perceptually similar nonsolid substances described as belonging either to the toy domain or the food domain. In a forced-choice task, participants extended the novel words to one of two test items: a same-shape test item (i.e., one that shared a common shape with the standard but differed in colour, texture, or smell) or a same-substance test item (i.e., one that shared a common colour, texture, and smell with the standard but differed in shape). Participants made more same-shape choices in the solid than in the nonsolid conditions. This tendency varied depending on whether the same-shape item differed from the standard in colour, texture, or smell. Participants also made more same-shape choices for items described as toys than for the same items described as food. This tendency was consistent regardless of whether the same-shape item differed from the standard in colour, texture, or smell. The findings confirm previous reports that children's word extensions are affected by the solidity of the referent. They also reveal that these extensions are guided by information about the referent's conceptual domain. Finally, these results provide the first evidence that these extensions are influenced by the smell, texture, and colour of the referent.

description: Three-body and four-body interactions have been directly measured in a colloidal system comprised of three (or four) charged colloidal particles. Two of the particles have been confined by means of a scanned laser tweezers to a line-shaped optical trap where they diffused due to thermal fluctuations. By means of an additional focused optical trap a third particle has been approached and attractive three-body interactions have been observed. These observations are in qualitative agreement with additionally performed nonlinear Poissson-Boltzmann calculations. Two configurations of four particles have been studied experimentally as well and in both cases a repulsive four-body interaction term has been observed.
