description: Posture is a complex process determined by the interaction of several body structures. In the past years, different direct and indirect procedures have been proposed to understand how these anatomical structures could be modified by forces exerted during sport practice (Queen et al, 2007). A particular attention has been focused on the variations in athletes from different sports to highlight eventual correlations between morpho-functional modifications, postural diseases and injuries (Cain et al, 2007). The aim of this work is to study the morphological aspects of the footprint and the spine in different athletes by an integrate approach. 115 subjects were tested and divided accordingly to the specific sport activity (control, basketball, volleyball, football, gymnastics); only subjects without previous or current diseases of the bones, joints and muscles have been considered. The electronic baropodometry has been used to measure the pressure distribution exerted on each foot during static and dynamic conditions; the Surfacer has been used to record the position of chosen points on the back. Our results indicated that, in comparison with controls, athletes from different sports displayed specific and significant modifications in foot type and in the back morphology; in particular, statistical analysis showed that in basketball and gymnastics athletes, significant changing in foot type and in the back morphology were present; moreover, in volleyball athletes, significant changing were found in foot type. Therefore, our results suggest that each sport could determinate specific postural changes during sport practice. Our data could be useful to develop specific training protocols aimed to prevent alterations in spine morphology and foot type that are associated with sport practice and could determine injuries or other postural diseases.

The influence of water sorption on the dynamic mechanical properties of nylon 6-6 and the plasticising effect of water.
Creators: name: Quistwater, Jacques Marie Raymond
Publisher: name: University of British Columbia

description: Much work has recently been done on studies of mechanical and electrical dispersion phenomena in polymers. Many workers have been active studying the effect of plasticisers, irradiation, heat, and mechanical treatment, copolymerisation, and cross-linking, such as vulcanisation, on a large number of high polymers. In spite of its great technological importance, the effect of humidity on the mechanical properties of textile fibres has not been studied in a systematic way. The present investigation is an attempt at studying the influence of humidity on the modulus and energy dissipation of nylon 6-6 monofilaments. The modulus and energy loss were determined using a low-frequency vibrometer, over the full range of relative humidities at 9, 35, and 60 °C., using 15 denier nylon monofilaments. Values of these empirical quantities were plotted as functions of frequency and humidity, and water content. The results were discussed taking into account the fact that water sorbed by fibres is present predominantly in the amorphous regions, and might be expected to break hydrogen bonds existing between adjacent peptide links, thereby reducing molecular interaction, and facilitating segmental motion. A mechanism was proposed in order to explain the results. The values of the tangent of the loss angle were compared with recent work by Sauer at al. Using expressions derived by Ferry and coworkers, apparent activation energies for the flow processes were calculated at a number of fixed water contents, and were found to vary between 26.3 and 110 kcal./mole.

Un nuovo approccio basato su osservazioni del cielo ad elevata risoluzione spaziale potrebbe fornire un ottimo test per identificare definitivamente un segnale caratteristico associato alla materia oscura. E' quanto emerge da uno studio, pubblicato su Physical Review D, secondo cui gli ammassi di galassie interagenti rappresenterebbero il miglior banco di prova per valutare statisticamente l'attendibilità dell'emissione X o gamma riconducibile alla presenza di questa enigmatica componente.

description: Trisomy 21, or Down’s syndrome, is the most common genetic cause of intellectual disability; moreover, DS patients suffer from muscle hypotonia and low muscle strength whose mechanisms are still unknown and only partially explained by intellectual disability. Genetic mouse models (e.g., the Ts65Dn mouse) may offer insights into the responsible mechanisms . Moreover, the Ts65Dn mouse show muscle weakness and share morphological similarities with sarcopenia of aging [1]. To characterize skeletal muscle in theTs65Dn model, we explored the hindlimb of young adult (6-month-old) mice in euploid (n=9, mean weight: 43.8±4.10 g) and trisomic (n=9, mean weight: 38.2±4.0 g ) individuals by magnetic resonance imaging. Mice were imaged in a Bruker Tomograph at 4.7 Tesla using a RARE T2-weighed sequence (TR: 5000ms, TE: 56ms; spatial resolution 0.0182cm2 per pixel). Muscle cross sectional area was measured in a section taken at mid-femur in either hindlimbs and values averaged for further analysis. Results showed that mean hindlimbs muscle cross sectional area was larger in trisomic than in euploid mice (0.29±0.05 vs. 0.23±0.05 cm2, p=0.03 [t test]). Because of significant difference in body weight between euploid and trisomic mice (p=0.009), data were adjusted per body weight. Using adjusted data, a significant difference was still found between groups (euploid: 0.005±0.001; trisomic: 0.007±0.001 cm2/g body weight). It is concluded that young adult trisomic mice has increased apparent muscle mass in hindlimbs. Since trisomic Ts65Dn mice show reduced grip strength as well as running and swimming speed in the presence of roughly normal muscle biochemistry [2], possible structural and fibertype changes in hindlimb muscles of these mice are under investigation to explain such a discrepancy.

description: The production of K+ and K- mesons below and at the NN threshold is summarized, based on a comparison of data with transport model calculations. K+ mesons are created in associate production together with hyperons (e.g. Lambda) in multi-step processes involving Delta resonances. These processes occur mainly during the high-density phase of the collision and this makes the K+ an ideal tool to extract the stiffness of the nuclear equation of state, found to be rather soft with a compressibility modulus K below 240 MeV. In contrast, the major part of K- mesons are produced via strangeness exchange. Most of the created K- are absorbed and the surviving ones are emitted quite late and at low densities.

description: We study the response of the QCD vacuum to an external abelian chromomagnetic field in the framework of a non local Nambu-Jona Lasinio model with the Polyakov loop. We use the Lattice results on the deconfinement temperature of the pure gauge theory to compute the same quantity in the presence of dynamical quarks. We find a linear relationship between the deconfinement temperature with quarks and the squared root of the applied field strength, $gH$, in qualitative (and to some extent also quantitative) agreement with existing Lattice calculations. On the other hand, we find a discrepancy on the approximate chiral symmetry restoration: while Lattice results suggest the deconfinement and the chiral restoration remain linked even at non-zero value of $gH$, our results are consistent with a scenario in which the two transitions are separated as $gH$ is increased.

The pyrolysis of diallyl and reactions of allyl radicals with l-butene.
Creators: name: Ruzicka, Dalibor Josef
Publisher: name: University of British Columbia
Year: 2012

description: A study has been made of the pyrolysis of 1,5-hexadiene (diallyl) and of the reactions of the allyl radicals thus produced with 1-butene. The pyrolysis of 1,5-hexadiene was found to be first order and appears to proceed mainly by free radical reactions in the temperature range 460 - 520° C. However, molecular rearrangement in the formation of cyclohexene and benzene are possible. The over-all activation energy for the process was found to be 31.3 kcal/mole for an A factor of 10⁸˙⁵ min¯¹. The main products among the gaseous compounds were methane, ethane, ethylene, propylene, and 1-butene. The main liquid products were cyclopentene, cyclopentadiene, 1-hexene and benzene. Evidence was obtained for hydrogen abstraction by allyl and addition of the allyl radical to olefinic double bonds. Activation energies for the formation of methane, ethane, propane, ethylene, propylene and 1-butene were determined. Addition of approximately 5 % by volume of 1,5-hexadiene was found to increase the rate of the pyrolysis of 1-butene about 6-7 times at 506° C. The formation of C₅-cyclic products and methane was found to be proportional to (diallyl)½ . This provides kinetic evidence that allyl radicals are involved directly in the formation of these products in the sensitized decomposition and also that the primary step in the pyrolysis of diallyl involves the formation of two allyl radicals. Mechanism for the pyrolysis of diallyl and for the reactions of allyl with 1-butene are discussed. A brief study has also been made of the pyrolysis of 1-butene in the presence of acetaldehyde. The thermal decomposition of 1-butene sensitized by addition of 25% by volume of acetaldehyde was carried out at 477° C. The decomposition of acetaldehyde was found to be inhibited by the presence of 1-butene by a factor of more than two. 1-butene, which practically does not decompose at the above temperature by itself, decomposes appreciably in the presence of acetaldehyde.

Subjects: Parkinson’s disease; VGF peptides; substantia nigra.

description: Parkinson’s disease (PD) is a neurological disorder characterized by a progressive degeneration of dopaminergic neurons of the substantia nigra, that results in dopamine depletion in the striatum with a deregulation of a number of substances/ neurotrasmitters. A previous study demonstrated a clear-cut decrease of certain peptides derived from the VGF gene in the parietal cortex from patients affected by PD. Hence, we used an animal model of PD, and plasma samples from PD patients and control subjects to investigate the role of VGF in PD. Rats (Sprague Dawley) were treated with injections of 6 hydroxydopamine into the medial forebrain bundle, anesthetized and perfused with 4% paraformaldehyde 3 weeks (group 1: n= 8) or 6 weeks (group 2: n=17) after injection. In addition, subcutaneous injections of L-DOPA (6mg/ Kg) were carried out one week before the sacrifice in rats from group 1 and 2 (n=4 and n=6, respectively). We raised antibodies to the C-terminal end of the human VGF sequence, for immunohistochemistry (IHC) and enzyme-linked immunosorbent assay (ELISA, IC50 = 15 pmol/ml). For pilot experiments, human plasma samples were taken from subjects affected by PD (n=13, age range: 51–84 years), and from age matched controls (n=10), to be used for ELISA experiments. We analysed the substantia nigra (SN) of the PD rats using VGF-C-terminus antiserum in double staining with antibodies to glutamate decarboxylase (GAD), tyrosine hydroxylase (TH), serotonin and Substance P. In the control side, VGF-C-terminus peptides were found in neurone terminals/axons within the pars compacta (SNC) and reticulata (SNR) of the substantia nigra, co-localised with GAD and substance P (but not with serotonin or TH) and in closed connection with TH cell bodies of the SNC. In the PD side, while the GAD staining remains unaffected, VGF-C-terminus and substance P immnureactivities disappeared (compared to the control side) in a large population of neurone terminals of both SNC and SNR, and in relation with the TH decrease. When L-DOPA was applied to the animals, VGF-C-terminus immunoreactivity on the PD side returned comparable to the control side. By ELISA, high concentrations of proVGF, in the order of 600-2000 pmol/ml were shown in the plasma from controls with a significant decrease in PD samples (p=0,0029). In conclusion, using the animal models, we showed here for the first time that VGF is involved into nigro-striatal circuits and down-regulated in PD. Besides, of a great interest, is the finding that a deregulation of VGF can occur also in humans.

description: Thanks to the development of dedicated CBCT scanners, 3D cephalometric analysis is become a widely used tool for the diagnosis and treatment of dentofacial disharmonies in maxillofacial surgery and dentistry [1]. Traditionally, an expert manually annotates a set of cephalometric landmarks on a CBCT scan. Accuracy and repeatability of this manual approach are limited because of intra- and inter-subject variability in landmarks identification [2]. To improve the manual annotation, we are developing a nearly-automatic method that estimates the positions of a set of landmarks registering a previously annotated reference subject to the patient skull. In this study, in order to reduce the estimation error, we compare different registration approaches by varying two registration parameters, such as elasticity (affine or elastic) and domain (local or global) of geometric transformation. The algorithms were tested on 21 CBCT scans of adult caucasian women. To evaluate the outcome of the registration process, Euclidean distances in the 3D space between automatically and manually annotated landmarks were computed. Finally, for each landmark, accuracy and precision of the annotation process were calculated as the mean and standard deviation of the distances of the analyzed sample. Results show that the combination of a global affine registration followed by a global elastic registration significantly reduces the annotation error (p<0.001), increasing both accuracy (p<0.001) and precision (p>0.05). Paired Student’s t tests were used for comparisons. The obtained results are promising, nevertheless the study should be continued in order to reduce further estimation error.

A Spitzer Spectroscopic Survey of Low Ionization Nuclear Emission-line Regions: Characterization of the Central Source

description: We have conducted a comprehensive mid-IR spectroscopic investigation of 67 Low Ionization Nuclear Emission Line Regions (LINERs) using archival observations from the high resolution modules of the Infrared Spectrograph on board the Spitzer Space Telescope. Using the [NeV] 14 and 24um lines as active galactic nuclei (AGN) diagnostics, we detect active black holes in 39% of the galaxies in our sample, many of which show no signs of activity in either the optical or X-ray bands. In particular, a detailed comparison of multi-wavelength diagnostics shows that optical studies fail to detect AGN in galaxies with large far-IR luminosities. These observations emphasize that the nuclear power source in a large percentage of LINERs is obscured in the optical. Indeed, the majority of LINERs show mid-IR [NeV]14/[NeV]24um flux ratios well below the theoretical low-density limit, suggesting that there is substantial extinction toward even the [NeV]-emitting region . Combining optical, X-ray, and mid-IR diagnostics, we find an AGN detection rate in LINERs of 74%, higher than previously reported statistics of the fraction of LINERs hosting AGN. The [NeV]24um /[OIV]26um mid-IR line flux ratio in "AGN-LINERs" is similar to that of standard AGN, suggesting that the spectral energy distribution (SED) of the intrinsic optical/UV continuum is similar in the two. This result is in contrast to previous suggestions of a UV deficit in the intrinsic broadband continuum emission in AGN-LINERs. Consistent with our finding of extinction to the [NeV]-emitting region, we propose that extinction may also be responsible for the observed optical/UV deficit seen in at least some AGN-LINERs.

description: Advances in the upper airway imaging allow to better evaluate and understand their morphology, pathology and mechanics [1]. In particular, Cone beam CT technology (CBCT), with its isotropic spatial resolution, undistorted images, X-ray lower radiation exposure, versatility and relatively low cost, takes over other imaging modalities [2]. The purpose of this study is to evaluate whether CBCT scans can be valuable tools for the extraction of quantitative parameters to confirm the deviation of the nasal septum in a specific patient. First, we assessed the difference in angle of septal deviation, calculated as proposed by Orhan et al., among a control group and a patient group [3]. Subsequently, we evaluated the percentage difference between the volume of the upper airways in the right side and left side of the nose in the same sample. The measurements were performed on 23 CBCT scans of Caucasian adult women, divided into 7 control subjects and 16 patients. The results demonstrate that there is a significant difference both in the deviation angle (p<0.05) and in the volume difference between healthy and patient subjects (p<0.001). Duplicate measurements of the deviation angle and the volume found no significant difference (p>0.05); random errors explained 0.77% (angle) and 0.99% (volume) of the sample variance. Paired Student’s t tests were used for comparisons. In particular, the volume difference appears to be less sensitive to the presence of isolated cartilaginous ridges that increase the angle of deviation even if the septum is not pathological. This makes it more suited to the identification of this pathology. The obtained outcomes are encouraging and it is advisable to continue the study on a larger sample.

description: We have recently introduced the two new computing models of self-similar cellular automata and self-similar Petri nets. Self-similar automata result from a progressive, infinite tessellation of space and time. Self-similar Petri nets consist of a potentially infinite sequence of coupled transitions with ever increasing firing rates. Both models are capable of hypercomputations and can, for instance, ``solve'' the halting problem for Turing machines. We survey the main definitions and propositions and add new results regarding the indeterminism of self-similar cellular automata.

description: The investigations directed to creation of selective terahertz radiation emitter have been performed. The GaN/AlGaN heterostructures with high-mobility 2D electron gas have been fabricated. High degree of the 2D-electron heating (up to 400 K) have been obtained by means of lateral electric field. Spectra of the terahertz radiation reflection, transmission and emission have been studied in GaN/AlGaN heterostructure on sapphire substrate and spectral percularities due to 2D electrons have been revealed. Additionally, spectra of terahertz radiation reflection and transmission have been studied for the heterostructures with metallic grating on the surface. The possibility to observe the effects due to 2D plasmons is discussed.

Angular size test on the expansion of the Universe

description: Assuming the standard cosmological model as correct, the average linear size of galaxies with the same luminosity is six times smaller at z=3.2 than at z=0, and their average angular size for a given luminosity is approximately proportional to 1/z. Neither the hypothesis that galaxies which formed earlier have much higher densities nor their luminosity evolution, mergers ratio, or massive outflows due to a quasar feedback mechanism are enough to justify such a strong size evolution. Also, at high redshift, the intrinsic ultraviolet surface brightness would be prohibitively high with this evolution, and the velocity dispersion much higher than observed. We explore here another possibility to overcome this problem by considering different cosmological scenarios that might make the observed angular sizes compatible with a weaker evolution. One of the models explored, a very simple phenomenological extrapolation of the linear Hubble law in a Euclidean static universe, fits the angular size vs. redshift dependence quite well, which is also approximately proportional to 1/z with this cosmological model. There are no free parameters derived ad hoc, although the error bars allow a slight size/luminosity evolution. The type Ia supernovae Hubble diagram can also be explained in terms of this model with no ad hoc fitted parameter. WARNING: I do not argue here that the true Universe is static. My intention is just to discuss which theoretical models provide a better fit to the data of observational cosmology.

description: It is widely accepted that glioblastoma (GBM) develops from cancer stem cells (CSCs), a subset of stem-like cells displaying high resistance to treatment. In fact, despite aggressive therapy, 90% of patients relapse within 2 cm from tumor edge. Our recent findings showed the existence of a CSC type, residing in GBM peritumor tissue (PCSCs), that bears distinct characteristics from CSCs of the tumor mass (GCSCs). It should be considered the possibility that, after surgical resection, PCSCs might represent a reservoir of cells able to recapitulate the tumor. In this setting, characterization of PCSCs appears to be crucial in order to identify novel effective therapeutic targets. Thus, our aim was to investigate GCSCs and PCSCs role in angiogenesis, a key event in both GBM and peritumor tissue, whose vasculature shows features similar to those found in the tumor mass. In particular, we analyzed, by immunocytochemistry (ICC), Western blotting or real-time PCR, the expression of molecules involved in hypoxia and angiogenesis, such as HIF1α, HIF2α, and VEGF along with its receptors (VEGFR1, VEGFR2). ICC has highlighted the presence and the specific localization of these molecules in both GCSCs and PCSCs. The two cell populations showed comparable levels of VEGF. The transcript of VEGFR1 was in general expressed at higher levels in GCSCs than in PCSCs, while VEGFR2 mRNA and protein did not show a unique trend of expression. The expression of VEGF and its receptors in both GCSCs and PCSCs suggests that, besides well-known paracrine loops, autocrine signalings are also involved in tumor angiogenesis. Moreover, the expression of angiogenesis markers in PCSCs suggests these cells to have a direct role in peritumor tissue new vessel formation. In this regard, PCSCs should be considered a promising therapeutic target to counteract the angiogenesis-supported tumor progression.

description: This paper employs two step systems GMM to analyse the effect of institutional quality on economic growth for Sub-Saharan African countries for the period from 2006 to 2018. The findings show that an improvement on institutional quality positively and significantly improve Sub-Saharan African countries output. The findings further provide evidence that the effect of institutional quality on output varies with regional location of SSA countries. In particular, institutional qualities are more effective in driving income growth in West African region than the other three regions of Eastern Africa and Central Africa. In addition, the findings indicate that the impact of institutional quality on output growth varies with income level of SSA countries. An improvement in intuitional quality is more likely to improve economic performance of low income SSA economies than the middle income SSA countries. SSA countries should strengthen independent institutional bodies that prosecute economic crimes. Also, African countries should support African agendas that are aligning with global development agenda. Sub-Saharan African countries should strengthen institutions that widen democratic space, civil liberty and the participation of citizen in the development agenda of a country.
Violation of smooth observable macroscopic realism in a harmonic oscillator

description: We study the emergence of macrorealism in a harmonic oscillator subject to consecutive measurements of a squeezed action. Since the harmonic oscillator dynamics admits a hidden trajectory formulation, the assumptions of macrorealism are violated only by the measurement process. We demonstrate a breakdown of macrorealism in a wide parameter range that is maximized in a scaling limit of extreme squeezing. A semiclassical analysis shows that macrorealism is violated even with measurements of classically smooth observables that do not resolve quantum levels. We propose an experimental test of macrorealism with entangled photons by demonstrating that local realism in a composite system implies macrorealism in a subsystem.

Interplay among spin, orbital effects and localization in a GaAs two-dimensional electron gas in a strong in-plane magnetic field

description: The magnetoresistance of a low carrier density, disordered GaAs based two-dimensional (2D) electron gas has been measured in parallel magnetic fields up to 32 T. The feature in the resistance associated with the complete spin polarization of the carriers shifts down by more than 20 T as the electron density is reduced, consistent with recent theories taking into account the enhancement of the electron-electron interactions at low densities. Nevertheless, the magnetic field for complete polarization, Bp, remains 2-3 times smaller than predicted for a disorder free system. We show, in particular by studying the temperature dependance of Bp to probe the effective size of the Fermi sea, that localization plays an important role in determining the spin polarization of a 2D electron gas.
