description: Spreadsheets have grown up and became very powerful and easy to use tools in applying analytical techniques for solving business problems. Operations managers, production managers, planners and schedulers can work with them in developing solid and practical Do-It-Yourself Decision Support Systems. Small and Medium size organizations, can apply OR methodologies without the presence of specialized software and trained personnel, which in many cases cannot afford anyway. This paper examines an efficient approach in solving combinatorial programming problems with the use of spreadsheets. A practical application, which demonstrates the approach, concerns the development of a spreadsheet-based DSS for the Multi Item Procurement Problem with Fixed Vendor Cost. The DSS has been build using exclusively standard spreadsheet feature and can solve real problems of substantial size. The benefits and limitations of the approach are also discussed.

description: The Pierre Auger Observatory reports that 20 of the 27 highest energy cosmic rays have arrival directions within 3.2 deg of a nearby galaxy in the Veron-Cetty & Veron Catalog of Quasars and Active Galactic Nuclei (12th Ed.), with ~5 of the correlations expected by chance. In this paper we examine the correlated galaxies to gain insight into the possible UHECR sources. We find that 14 of the 21 correlated VCV galaxies are AGNs and we determine their bolometric luminosities. The remaining 7 are primarily star-forming galaxies. The bolometric luminosities of the correlated AGNs are all greater than 5 x 10^{42} erg/s, which may explain the absence of UHECRs from the Virgo region in spite of the large number of VCV galaxies in Virgo, since most of the VCV galaxies in the Virgo region are low luminosity AGNs. Interestingly, the bolometric luminosities of most of the AGNs are significantly lower than required to satisfy the minimum condition for UHECR acceleration in a continuous jet. If a UHECR-AGN correlation is substantiated with further statistics, our results lend support to the recently proposed ``giant AGN flare" mechanism for UHECR acceleration.

description: Recently W. J. Kim, M. Brown-Hayes, D. A. R. Dalvit, J. H. Brownell, and R. Onofrio [Phys. Rev. A, v.78, 036102(R) (2008)] performed electrostatic calibrations for a plane plate above a centimeter-size spherical lens at separations down to 20-30 nm and observed "anomalous behavior". It was found that the gradient of the electrostatic force does not depend on separation as predicted on the basis of a pure Coulombian contribution. Some hypotheses which could potentially explain the deviation from the expected behavior were considered, and qualitative arguments in favor of the influence of patch surface potentials were presented. We demonstrate that for the large lenses at separations of a few tens nanometers from the plate, the electrostatic force law used by the authors is not applicable due to possible deviations of the mechanically polished and ground lens surface from a perfect spherical shape. A model is proposed which explains the observed "anomalous behavior" using the standard Coulombian force.

Characterization of recombinant plasmids carrying Drosphila melanogaster tRNA Serine7 genes and their preparation for DNA sequencing
Creators: name: Spurr, Mark Gregory
Publisher: name: University of British Columbia
Year: 2010

description: Specific Drosphila tRNA Ser4,7 plasmids were identified and isolated by hybridization with purified [¹²⁵I] tRNA Ser4,7 molecules. Seven clones were isolated carrying the Drosphila Ser tRNA Ser4,7 gene and were further characterized by restriction endonuclease digestion; agarose gel electrophoresis and hybridization with individual purified [¹²⁵I] tRNA Ser4,7 molecules. The results show that five different DNA fragments have been isolated, four which code for a single, specific isoacceptor, and one which appears to code for two different isoacceptors. Two plasmids which initially contained multiple Hind III inserts upon primary isolation were recloned to contain single Hind III inserts containing the tRNA Ser4,7 gene. One of these recloned plasmids contained a smaller tRNA Ser4,7 gene carrying insert than did its original multiple insert isolate. Small tRNA Ser4,7 gene carrying restriction fragments were labelled with T4 polynucleotide kinase and [³²P] ATP, strand separated, and electroeluted, in preparation for nucleotide sequencing.

description: Nel saggio descrivo le tracce di materiale proveniente dalla tradizione orientale nel canzoniere provenzale C, attraverso un’analisi delle serie e della varia lectio, prima nella sezione di Giraut de Borneil, e poi in quelle di altri autori. In conclusione propongo due ipotesi ricostruttive: la prima riconduce le tracce di tale materiale a un livello alto nello stemma della tradizione manoscritta trobadorica; la seconda suggerisce l’arrivo in Provenza dall’Italia di materiale manoscritto già strutturato, con una fisionomia simile a Da/IK.

The work describes the traces of written materials coming from the Eastern trobadoric tradition into the chansonnier C. It analyses both the disposition of the texts in the manuscript and the varia lectio, starting from the authorial section of Giraut de Borneil and then approaching the sections of other authors. The proposed results lead to two hypotheses: the first one brings back the traces of Eastern materials to an ancient initial moment in the trobadoric tradition; the second one suggests that an already organised manuscript materials (similar to our manuscripts DaIK) arrived from Italy into the regions of Southern France.

Spacing behavior of snowshoe hares in relation to their population dynamics
Creators: name: Boutin, Stanley A.
Publisher: name: University of British Columbia
Year: 2010

description: The importance of spacing behavior on snowshoe hare population dynamics was studied in the Kluane Lake, Yukon area from May 1978 to July 1979. Two study sites, each consisting of a 9.29 ha live-trapping grid, were used to capture and tag animals. Numbers were increasing over the study with May breeding densities going from 8 in 1978 to 20 in 1979. The increase was a result of higher than average (12.25 young caught per female) natality rates. Yearly juvenile and adult survival rates were equal at 20%. A total of 116 hares were equipped with radio-transmitters during the study. These were monitored to determine home range locations and individual movements. Home ranges overlapped by at least 30% between and within sexes throughout the year. Home ranges averaged larger for males (4-8 ha) than females (3-5 ha). During periods of birth, females contracted the size of their home range but not significantly. 14 radio-tagged individuals dispersed during the study. They moved an average of 1045 m and were from all age and sex classes with the exception of adult males. To determine the importance of spacing behavior on breeding females' home ranges and movements I removed a small group of individuals from a much larger group of radio-tagged animals. The initial removal was done 10 days before the birth of the first litters and was then repeated 10 days before birth of the second litters. Home ranges were monitored before and after each removal and compared to a control area. Females did not increase their use of the removal area nor was it colonized by individuals from beyond the ring of radio-tagged animals. This suggests that breeding female densities were not limited by spacing behavior. Females did shift use of their home range after the removal by spending up to 30% more time on the removal side of their range. This suggests that females use their range in a manner that avoids interaction. Adult females were removed from one of the study areas during the late breeding season to assess their influence on juvenile movements and survival. There were no significant differences in these aspects between the manipulated area and a control. However, telemetry showed that juvenile and adult female home ranges overlapped little on the control area during September. The movements to create this situation were done by juveniles at a time before they could be trapped or radio-tagged. This suggests that some juveniles may leave their parents' home ranges at a time prior to which is detectable by conventional trapping and telemetry. The need for further investigation in this area is stressed.

description: L’articolo si propone di studiare i canali attraverso i quali l’opera di Peire d’Alvernhe ha raggiunto l’età di compilazione dei canzonieri provenzali. Il contributo analizza il numero e la disposizione dei testi conservati in ciascun canzoniere e, passando attraverso lo studio della varia lectio, individua sei fonti principali, di cui tre tra le più antiche a noi note (tradizione musicale, tradizione catalana, tradizione italiana ε+β). Inoltre, lo studio tenta di astrarre dal caso concreto di Peire d’Alvernhe alcuni comportamenti tipici dei compilatori dei canzonieri: operazioni di recensione di materiali di diversa provenienza, loro organizzazione in sezioni d’autore più complete, eventuale collazione dei materiali ed eventuale revisione testuale. Lo studio puntuale della sezione di Peire d’Alvernhe in ogni ms. ha permesso infine di rettificare alcune sviste che persistevano nella tradizione di studi.

The paper aims to study the channels through which Peire d’Alvernhe’s poetry was able to reach the time when the Provençal chansonniers have been produced. Analysing the number and disposition of the texts preserved by each manuscript, and taking into account the lessons found in the varia lectio, it’s possible to recognize six main sources: among them we find the musical tradition, the Catalan tradition and the Italian tradition ε+β, which are three of the most ancient sources of Provençal poetry. In addition, the particular case of Peire d’Alvernhe unfolds some aspects of the work of the medieval ‘editors’: recension of texts coming from different sources, their organisation in a new completer authorial section, their possible collation and textual editing. Finally, it’s possible to rectify some oversights found in previous bibliography.

description: The Fornax cluster provides an unparalleled opportunity to investigate in detail the formation and evolution of early-type galaxies in a dense environment. We aim at kinematically characterizing photometrically detected globular cluster (GC) candidates in the core of the cluster. We used the VLT/VIMOS spectroscopic data from the FVSS survey in the Fornax cluster, covering one square degree around the central massive galaxy NGC 1399. We confirmed a total of 777 GCs, almost doubling the previously detected GCs, using the same dataset by Pota et al. (2018). Combined with previous literature radial velocity measurements of GCs in Fornax, we compiled the most extensive spectroscopic GC sample of 2341 objects in this environment. We found that red GCs are mostly concentrated around major galaxies, while blue GCs are kinematically irregular and are widely spread throughout the core region of the cluster. The velocity dispersion profiles of blue and red GCs show a quite distinct behaviour. Blue GCs exhibit a sharp increase in the velocity dispersion profile from 250 to 400km/s within 5 arcminutes (29 kpc/1 reff of NGC 1399) from the central galaxy. The velocity dispersion profile of red GCs follows a constant value in between 200-300km/s until 8 arcminutes (46 kpc/1.6reff), and then rises to 350km/s at 10 arcminutes (58 kpc/2 reff). Beyond 10 arcminutes and out to 40 arcminutes (230 kpc/8 reff), blue and red GCs show a constant velocity dispersion of 300+/-50km/s, indicating that both GC populations are tracing the cluster potential. We have kinematically confirmed and characterized the previously photometrically discovered overdensities of intra-cluster GCs. We found that those substructured intra-cluster regions in Fornax are dominated mostly by blue GCs.

24 hr noise exposure aboard US navy aircraft carriers
Creators: name: Schaal, Nicholas

Publisher: name: F1000 Research Limited
Year: 2019

description: Background: Personnel assigned to aircraft carriers are exposed to a variety of noise sources from equipment and flight deck operations for durations >12 h. Personnel work and live in environments where hazardous noise areas and hearing recovery spaces such as sleeping and relaxation areas are in proximity to one another which provides little recovery time from hazardous noise. This investigation describes noise levels measured over a 24-h period on a US Navy aircraft carrier during flight operations for different populations of aircraft carrier personnel.

Methods: Personal noise monitoring occurred from 23 to 28 January 2014 aboard a US Navy Nimitz-class aircraft carrier during a routine at-sea period. Fifty-nine study volunteers were assigned to similar exposure groups (SEGs). The SEGs were compared to determine which groups were at greatest risk of hazardous noise exposure. Statistical analysis was conducted with SPSS version 24 using an alpha level of 0.05.

Results: Mean 24-h equivalent continuous sound levels Leq(24-h) and on-duty time weighted averages (TWA(on-duty)) ranged from 71 to 127 decibels A weighted (dBA). The 80 dBA American Conference of Governmental Industrial Hygienists (ACGIH) threshold limit value (TLV) for 24-h noise exposure was exceeded by 93% of the study volunteers. The 85 dBA ACGIH TLV and Department of defense Occupational exposure limit for 8-h noise exposures was exceeded by 68% of the population. Leq(off-duty) ranged from 38 to 102 dBA with 61% of the population exceeding the 70 dBA ACGIH TLV classified as effective quiet to allow for temporary threshold shift recovery. SEG 2 Flight Deck Launch and Recovery had significantly higher 24-h noise exposures than SEG 3 Damage Control Maintenance and Repair (P = 0.01), SEG 5 Supply (P = 0.01), and SEG 7 Administrative/Professional (P = 0.009). Similar results were found for TWA(on-duty) noise exposures. Median TWA(on-duty) and Leq(24-h) for SEG 2 were 16–21 dB higher than SEG 3, 5, and 7. There were no significant differences between off-duty Leq noise exposures according to SEG.

Discussion/Conclusions: SEGs located on the flight deck (SEGs 1 and 2) and SEGs responsible for maintenance and repair activities (SEGs 3 and 4) supporting flight operations had the highest TWA(on- duty) and Leq(24-h). These findings raise serious concerns because high noise exposures both on- and off-duty may result in immediate acoustic trauma and development of temporary threshold shifts, which, if unresolved with auditory rest, may lead to permanent hearing loss.

Auditory-visual integration of temporal relations in infants
Creators: name: Humphrey, Gary Keith
Publisher: name: University of British Columbia
Year: 2010

description: Three experiments examined auditory-visual integration of temporal relations by infants. In the first experiment infants of 3, 6 and 10 months of age were placed midway between two flashing visual displays. Tones, temporally synchronized to one of the visual displays, emanated from concealed speakers placed midway between the visual displays directly in front of the infants. The visual displays, and corresponding tones differed in temporal rate by a factor of four. No evidence was found for differential looking to the sound-specified visual pattern in any of the three age levels tested. The 3-month-olds showed a strong right-looking bias regardless of visual pattern or temporal rate of the tone, while the 10-month-olds preferred to look at the fast visual pattern regardless of position or tone rate. Both of these biases impaired the effectiveness of the simultaneous presentation paradigm to detect differential looking related to auditory-visual synchrony. Experiments II and III used an habituation methodology which eliminated any effects of position and rate bias. Only 4-month-old infants were tested. In each experiment, one group of infants was first presented with temporally synchronous auditory and visual signals during habituation trials and then nonsynchronous signals during recovery trials. Two other groups of infants, one in each experiment, received the opposite sequence. In Experiment II the auditory and visual signals were spatially congruous, but they were separated by 90° in Experiment III. Since the pulse rate of the visual stimuli was changed for the nonsynchronous trials, a control group was tested which received only the light during habituation and recovery trials. Both groups initially presented with synchronous signals showed habituation and recovery. Neither group presented with nonsynchronous stimuli during habituation trials demonstrated recovery and only the group with the spatially separated sources habituated. The results suggest that 4-month-old infants are able to coordinate the temporal relations between auditory and visual signals.

description: Fifth generation (5G) networks are expected to connect a huge number of Internet of Things (IoT) devices in many usage scenarios. The challenges of typical massive IoT applications with sporadic and short packet uplink transmissions are well studied, while not enough attention is given to the delivery of content of common interest, such as software/firmware updates and remote control, towards IoT devices in emerging point-to-multipoint scenarios. Moreover, the delivery of delay-sensitive IoT traffic is not sufficiently addressed in the literature. In this work we (i) identify the drawbacks of the current Single-Cell Point-to-Multipoint (SC-PTM) solution for unplanned critical traffic delivery in cellular IoT (cIoT) networks, and (ii) propose paging and multicast schemes for a fast distribution of critical updates after, e.g., bug fixes or system failures. We benchmark the performance of the proposed paging scheme against similar solutions available in the literature. Our extended SC-PTM framework is energy efficient and guarantees low service latency, as demonstrated both analytically and by simulations.

description: Current research on Explainable AI (XAI) heavily targets on expert users (data scientists or AI developers). However, increasing importance has been argued for making AI more understandable to nonexperts, who are expected to leverage AI techniques, but have limited knowledge about AI. We present a mobile application to support nonexperts to interactively make sense of Convolutional Neural Networks (CNN); it allows users to play with a pretrained CNN by taking pictures of their surrounding objects. We use an up-to-date XAI technique (Class Activation Map) to intuitively visualize the model's decision (the most important image regions that lead to a certain result). Deployed in a university course, this playful learning tool was found to support design students to gain vivid understandings about the capabilities and limitations of pretrained CNNs in real-world environments. Concrete examples of students' playful explorations are reported to characterize their sensemaking processes reflecting different depths of thought.

description: The Parker Solar Probe (PSP) spacecraft is performing the first in situ exploration of the solar wind within 0.2 au of the Sun. Initial observations confirmed the Alfvénic nature of aligned fluctuations of the magnetic field B and velocity V in solar wind plasma close to the Sun, in domains of nearly constant magnetic field magnitude $|{\bf B}|$, i.e., approximate magnetic pressure balance. Such domains are interrupted by particularly strong fluctuations, including but not limited to radial field (polarity) reversals, known as switchbacks. It has been proposed that nonlinear Kelvin-Helmholtz instabilities form near magnetic boundaries in the nascent solar wind leading to extensive shear-driven dynamics, strong turbulent fluctuations including switchbacks, and mixing layers that involve domains of approximate magnetic pressure balance. In this work we identify and analyze various aspects of such domains using data from the first five PSP solar encounters. The filling fraction of domains, a measure of Alfvénicity, varies from median values of 90% within 0.2 au to 38% outside 0.9 au, with strong fluctuations. We find an inverse association between the mean domain duration and plasma $β$. We examine whether the mean domain duration is also related to the crossing time of spatial structures frozen into the solar wind flow for extreme cases of the aspect ratio. Our results are inconsistent with long, thin domains aligned along the radial or Parker spiral direction, and compatible with isotropic domains, which is consistent with prior observations of isotropic density fluctuations or ``flocculae'' in the solar wind.

description: We present a radial velocity study of the rapidly rotating B-star Regulus that indicates the star is a single-lined spectroscopic binary. The orbital period (40.11 d) and probable semimajor axis (0.35 AU) are large enough that the system is not interacting at present. However, the mass function suggests that the secondary has a low mass (M_2 > 0.30 M_sun), and we argue that the companion may be a white dwarf. Such a star would be the remnant of a former mass donor that was the source of the large spin angular momentum of Regulus itself.

description: Organic salts represent an ideal experimental playground for studying the interplay between magnetic and charge degrees of freedom, which has culminated in the discovery of several spin-liquid candidates, such as $κ$-(ET)$_2$Cu$_2$(CN)$_3$ ($κ$-Cu). Recent theoretical studies indicate the possibility of chiral spin liquids stabilized by ring-exchange, but the parent states with chiral magnetic order have not been observed in this material family. In this work, we discuss the properties of the recently synthesized $κ$-(BETS)$_2$Mn[N(CN)$_2$]$_3$ ($κ$-Mn). Based on analysis of specific heat, magnetic torque, and NMR measurements combined with ab initio calculations, we identify a spin-vortex crystal order. These observations definitively confirm the importance of ring-exchange in these materials, and support the proposed chiral spin-liquid scenario for triangular lattice organics.

description: According to the fundamental principle of evolutionary game theory, the more successful strategy in a population should spread. Hence, during a strategy imitation process a player compares its payoff value to the payoff value held by a competing strategy. But this information is not always accurate. To avoid ambiguity a learner may therefore decide to collect a more reliable statistics by averaging the payoff values of its opponents in the neighborhood, and makes a decision afterwards. This simple alteration of the standard microscopic protocol significantly improves the cooperation level in a population. Furthermore, the positive impact can be strengthened by increasing the role of the environment and the size of the evaluation circle. The mechanism that explains this improvement is based on a self-organizing process which reveals the detrimental consequence of defector aggregation that remains partly hidden during face-to-face comparisons. Notably, the reported phenomenon is not limited to lattice populations but remains valid also for systems described by irregular interaction networks.

description: We report on direct imaging of vortex matter nucleated in micron-sized Bi2Sr2CaCu2O8+y superconducting samples that incidentally present a bridge structure. We find that when nucleating vortices in a field-cooling condition the deck of the bridge acts as a converging lens for vortices. By means of Bitter decoration images allowing us to quantify the enhancement of vortex-vortex interaction energy per unit length in the deck of the bridge, we are able to estimate that the deck is thinner than 0.6\,$μ$m. We show that the structural properties of vortex matter nucleated in micron-sized thin samples are not significantly affected by sample-thickness variations of the order of half a micron, an important information for type-II superconductors-based mesoscopic technological devices.

description: We employ a recently developed methodology -- called "structural refinement" -- to extract nested sequent systems for a sizable class of intuitionistic modal logics from their respective labelled sequent systems. This method can be seen as a means by which labelled sequent systems can be transformed into nested sequent systems through the introduction of propagation rules and the elimination of structural rules, followed by a notational translation. The nested systems we obtain incorporate propagation rules that are parameterized with formal grammars, and which encode certain frame conditions expressible as first-order Horn formulae that correspond to a subclass of the Scott-Lemmon axioms. We show that our nested systems are sound, cut-free complete, and admit hp-admissibility of typical structural rules.
Genetic and epidemiologic aspects of multiple sclerosis in British Columbia

description: The etiology of multiple sclerosis (MS) remains unknown despite much research. The controversy about a genetic component to MS has been going on for nearly a century. Using various sources, the two main ones being the British Columbia (B.C.) Health Surveillance Registry and the B.C. Division of the MS Society of Canada, 983 persons, reported to have MS and living in B.C. on April 30, 1976, were ascertained. These data give a prevalence rate for the province of 39.9 per 100,000 population and a female:male sex ratio of 1.9:1. These findings are what is expected for a northern, temperate region such as B.C. Genetic and medical histories were obtained for 416 of the ascertained patients. Empiric familial recurrence risks, needed for genetic counselling, were derived for first, second, and third degree relatives of patients. The family data were tested for "goodness-of-fit" to the multifactorial two-threshold model of inheritance. This model was rejected on the basis that "too many" families with at least two affected siblings were observed than can be expected under the model. This is evidence for either (a) a genetic model with a higher recurrence risk than the multifactorial model or (b) genetic heterogeneity. There is evidence for phenotypic heterogeneity in MS. Patients with a family history of the disease tend to develop MS at an earlier age than do those with no family history. Pregnancy increases the risk of an exacerbation during a "pregnancy year", particularly during the three months postpartum. However, pregnancy does not appear to affect the long-term prognosis for MS. In summary, the results from this study confirm the findings of others that a genetic factor (or factors) is associated with the manifestation of MS and that there is an increased frequency of the disease among relatives of patients compared with the general population. While the precise genetic model is unclear, recurrence risk estimates have been derived for the first time. Hence genetic counselling is recommended for all MS patients and their families.

description: We develop information field theory (IFT) as a means of Bayesian inference on spatially distributed signals, the information fields. A didactical approach is attempted. Starting from general considerations on the nature of measurements, signals, noise, and their relation to a physical reality, we derive the information Hamiltonian, the source field, propagator, and interaction terms. Free IFT reproduces the well known Wiener-filter theory. Interacting IFT can be diagrammatically expanded, for which we provide the Feynman rules in position-, Fourier-, and spherical harmonics space, and the Boltzmann-Shannon information measure. The theory should be applicable in many fields. However, here, two cosmological signal recovery problems are discussed in their IFT-formulation. 1) Reconstruction of the cosmic large-scale structure matter distribution from discrete galaxy counts in incomplete galaxy surveys within a simple model of galaxy formation. We show that a Gaussian signal, which should resemble the initial density perturbations of the Universe, observed with a strongly non-linear, incomplete and Poissonian-noise affected response, as the processes of structure and galaxy formation and observations provide, can be reconstructed thanks to the virtue of a response-renormalization flow equation. 2) We design a filter to detect local non-linearities in the cosmic microwave background, which are predicted from some Early-Universe inflationary scenarios, and expected due to measurement imperfections. This filter is the optimal Bayes' estimator up to linear order in the non-linearity parameter and can be used even to construct sky maps of non-linearities in the data.

Subjects: AGR/20 Zoocolture

description: The purpose of the PhD research was the identification of new strategies of farming and processing, with the aim to improve the nutritional and technological characteristics of poultry meat. Part of the PhD research was focused on evaluation of alternative farming systems, with the aim to increase animal welfare and to improve the meat quality and sensorial characteristics in broiler chickens. It was also assessed the use of innovative ingredients for marination of poultry meat (sodium bicarbonate and natural antioxidants)
The research was developed by studying the following aspects:
- Meat quality characteristics, oxidative stability and sensorial traits of chicken meat obtained from two different farming systems: free range vs conventional;
- Meat quality traits of frozen chicken breast pre-salted using increasing concentrations of sodium chloride;
- Use of sodium bicarbonate in comparison with sodium trypolyphosphate for marination of broiler breast meat and phase;
- Marination with thyme and orange essential oils mixture to improve chicken meat quality traits, susceptibility to lipid oxidation and sensory traits.
The following meat quality traits analyseswere performed: 
Colour, pH, water holding capacity by conventional (gravimetric methods, pressure application, centrifugation and cooking) and innovative methods (low-field NMR and DSC analysis) ability to absorb marinade soloutions, texture (shear force using different probes and texture profile analysis), proximate analysis (moisture, proteins, lipids, ash content, collagen, fatty acid), susceptibility to lipid oxidation (determinations of reactive substances with thiobarbituric acid and peroxide value), sensorial analysis (triangle test and consumer test).

description: We investigate vortex configurations with the "vulcanization" term inspired by the renormalization of $ϕ_\star^4$ theory in the canonical $θ$-deformed noncommutativity. We focus on the classical limit of the theory described by a single parameter which is the ratio of the vulcanization and the noncommutativity parameters. We perform numerical calculations and find that nontopological vortex solutions exist as well as Q-ball type solutions, but topological vortex solutions are not admitted.
