description: It is shown that certain diffeomorphism or homeomorphism groups with no restriction on support of an open manifold with finite number of ends are bounded. It follows that these groups are uniformly perfect. In order to characterize the boundedness several conditions on automorphism groups of an open manifold are introduced. In particular, it is shown that the commutator length diameter of the automorphism group $\mathcal D(M)$ of a portable manifold $M$ is estimated by $2fragd_{\mathcal D(M)}+2$, where $fragd_{\mathcal D(M)}$ is the diameter of $\mathcal D(M)$ in the fragmentation norm.

On the logical operators of quantum codes

description: I show how applying a symplectic Gram-Schmidt orthogonalization to the normalizer of a quantum code gives a different way of determining the code's logical operators. This approach may be more natural in the setting where we produce a quantum code from classical codes because the generator matrices of the classical codes form the normalizer of the resulting quantum code. This technique is particularly useful in determining the logical operators of an entanglement-assisted code produced from two classical binary codes or from one classical quaternary code. Finally, this approach gives additional formulas for computing the amount of entanglement that an entanglement-assisted code requires.

description: Among various approaches for indirect detection of dark matter, synchrotron emission due to secondary electrons/positrons produced in galactic WIMPs annihilation is raising an increasing interest. In this paper we propose a new method to derive bounds in the mchi - plane by using radio continuum observations of Messier 33, paying particular attention to a low emitting Radio Cavity. The comparison of the expected radio emission due to the galactic dark matter distribution with the observed one provides bounds which are comparable to those obtained from a similar analysis of the Milky Way. Remarkably, the present results are simply based on archival data and thus largely improvable by means of specifically tailored observations. The potentiality of the method compared with more standard searches is discussed by considering the optimistic situation of a vanishing flux (within the experimental sensitivity) measured inside the cavity by a high resolution radio telescope like ALMA. Under the best conditions our technique is able to produce bounds which are comparable to the ones expected after five years of Fermi LAT data taking for an hadronic annihilation channel. Furthermore, it allows to test the hypothesis that space telescopes like Pamela and Fermi LAT are actually observing electrons and positrons due to galactic dark matter annihilation into leptons.

description: We show that three dimensional superconductors, described within a Bogoliubov de Gennes framework can have zero energy bound states associated with pointlike topological defects. The Majorana fermions associated with these modes have non-Abelian exchange statistics, despite the fact that the braid group is trivial in three dimensions. This can occur because the defects are associated with an orientation that can undergo topologically nontrivial rotations. A new feature of three dimensional systems is that there are "braidless" operations in which it is possible to manipulate the groundstate associated with a set of defects without moving or measuring them. To illustrate these effects we analyze specific architectures involving topological insulators and superconductors.

Il tempo di vita di un asteroide è determinato dalla sua resistenza agli impatti con altri corpi minori. In uno studio pubblicato oggi su Nature, gli scienziati della missione spaziale Osiris-Rex hanno stimato direttamente – per la prima volta – la resistenza agli impatti di un asteroide, e di conseguenza l’età superficiale assoluta dei massi che lo costituiscono. Lo studio, che parte da un’analisi dettagliata delle dimensioni e della profondità dei crateri osservati sui massi dell'asteroide Bennu, indica che il corpo è a tutti gli effetti un Near Earth Object da circa 1,75 milioni di anni.

description: The major challenge in the management of patients with oral squamous cell carcinomas (OSCC) is the development of resistance to therapy leading to disseminated disease. Since cancer stem cells (CSC) have emerged as important players in OSCC metastasis, our objectives were to explore the implications of CSC in OSCC tumor progression, invasion and response to conventional therapies. Methods: A panel of well-characterized cell lines originated from the most common sites in the head and neck area was used. Cells were cultured as floating spheres or under normal adherent conditions and analyzed for CD44, ALDH, CD24, CD29, CD56 by flow cytometry, PCR arrays for genes related to stemness, metastasis and EMT . We also investigated sLeX expression, known to play a key-role in many cancers metastasis by promoting tumor cells binding to endothelial E-selectin. We analyzed the tumorigenic potential of OSCC cells by invasion assays and in vivo OSCC experimental models comparatively to CSC cells. Moreover resistance to cisplatin and radiation was assessed by annexin V/PI assay and by colony forming assay. Results: The highest levels of sLeX expression were found in cell lines originated from oral cavity (9%-47%) compared to other head and neck locations (0.1%-7%). Cells grown as spheres were 95-100% positive for sLeX compared to 10-40% of adherent counterpart. Although sLeX+ and sLeX- cells were both able to form spheres, sLeX+ spheres were predominant and larger. Flow cytometry and PCR arrays indicated that the spheres were highly enriched in CSC and metastatic markers. Consistently, the spheres showed increased invasive and tumorigenic potential, and resistance to conventional chemotherapy and radiations. Conclusion: these studies are the first to unveil a novel link between sLeX expression, stem cell formation and metastatic spread in OSCC, and provide supportive evidence for CSC resistance to treatment. Understanding the mechanisms of tumor invasion and metastasis will improve patient outcome and survival.

description: Using long C_{N}H_{2} conjugated carbon chains with the polyynic structure as prototypical examples of one-dimensional (1D) semiconductors, we discuss self-localization of excess charge carriers into 1D large polarons in the presence of the interaction with a surrounding polar solvent. The solvation mechanism of self-trapping is different from the polaron formation due to coupling with bond-length modulations of the underlying atomic lattice well-known in conjugated polymers. Model ab initio computations employing the hybrid B3LYP density functional in conjunction with the polarizable continuum model are carried out demonstrating the formation of both electron- and hole-polarons. Polarons can emerge entirely due to solvation but even larger degrees of charge localization occur when accompanied by atomic displacements.

Trimethyltin-induced hippocampal degeneration in developing rats: Modulation of reelin expression and endogenous neurogenesis

description: Trimethyltin (TMT) is a neurotoxicant inducing in rats selective neuronal death, mainly localised in hippocampal regions. Reelin is an extracellular matrix glycoprotein essential for the radial migration of cortical neurons during development and for the integration of dentate granular cell progenitors. In the hippocampus, reelin modulates the synaptic plasticity, its expression being down-regulated as brain maturation is completed (reviews 1-3). We analyzed the expression of reelin, and the modulation of neurogenesis, in the postnatal rat hippocampus during TMT-induced neurodegeneration. BrdU-analysis indicated an enhancement of hippocampal neurogenesis in the subgranular zone of TMT-treated rats (P21 and P28), the newly generated cells differentiating essentially towards neurons. Immunohistochemistry and Real-time PCR revealed that reelin expression remained almost unmodified in treated rats, while a time-dependent down-regulation in the hippocampus of control rats was observed, as expected. Quantitative analysis of reelin-IR cells evidenced, in treated animals, a persistent reelin expression in the stratum lacunosum moleculare of Cornu Ammonis and in the molecular layer of Dentate Gyrus. Thus TMT treatment enhances endogenous neurogenesis and prevents the physiological developmental decrease of reelin. These results hint at the possibility that both phoenomena, in an integrated or distinct manner, might play a role in the tissue response to brain injury.

description: Peripheral neuropathies are in general characterized by hyperalgesia and allodynia with alterations of muscular sensitivity and functions. Selected antioxidants have been proposed as a potential therapeutic agents in the treatment or prevention of several pathologies related to oxidative stress. Thioctic acid is an antioxidant existing in nature and expressed in two optical isomers. (+)-Thioctic acid is the naturally occurring enantiomer, whereas the most used formulation of the compound in clinical practice, synthetic thioctic acid, is the mixture of (+) and (-)-enantiomers. The present study assessed if compression of sciatic nerve, induced by loose ligation, is accompanied by a central nervous system (CNS) changes and if thioctic acid enantiomers treatment may have a possible neuroprotective role. Loose ligation of the right sciatic nerve was performed in spontaneously hypertensive rats (SHR), used as a model of increased oxidative stress, and in normotensive Wistar-Kyoto rats (WKY) used as a control group. Animals with sciatic nerve ligation were left untreated or were treated intraperitoneally for 14 days with (+/-)-(25 and 50 mg/Kg/day), (+)-(25 mg/Kg/day), (-)-(25 mg/Kg/day) thioctic acid. Analysis, centered on injury phenomena at level of dorsal root ganglia and spinal cord, consisted in an immunochemical and immunohistochemical analysis. In the spinal cord an increase of oxidative stress markers was observed in rats after sciatic nerve ligation. It was accompanied by astrogliosis and neuronal damage without activation of apoptotic process primarily in in the dorsal horn of spinal cord. Antioxidant treatment reduced oxidative stress and astrogliosis being (+)-thioctic acid was active than (+/-)- or (-)-enantiomers. The above results demonstrated the spinal cord changes induced by peripheral nerve injury and a neuroprotective effect elicited by thioctic acid. The demonstration of a more pronounced activity of (+)-thioctic acid suggests that appropriate antioxidant strategies may represent a suitable approach in the treatment of mechanical neuropathies.

Subjects: digital anthropometry; dental arches; registration; CBCT; face

description: Digital 3D models of dental arches and facial soft tissues may constitute an important support for clinicians and maxillofacial surgeons. They can be obtained using a noninvasive and harmless method1 starting from acquisitions made with a dental scanner and a stereophotogrammetric device. The aim of the study was to compare measures taken on the 3D dental and facial models with the ones obtained through a Cone Beam Computed Tomography (CBCT) device in order to evaluate the reliability of the proposed method and its repeatability. Dental and facial data about a population of seven healthy subjects just undergone CBCT have been acquired and registered twice by three operators following a protocol devised for previous works published by this same laboratory2,3. Five craniofacial and six dental landmarks have been taken into account and their linear distances have been calculated. The errors between the corresponding distances in the alternative method and in the CBCT volume have been normalized on the corresponding distance measured on the CBCT model. Statistically significant differences between repetitions and operators were found in the distances between the orbitalis and dental landmarks. We assume that these differences might have been caused by the difficulty in the positioning of the craniofacial soft-tissue landmarks on the CBCT scans. Also the delicate steps for registering the models of the dental arches could have generated errors as it has been suggested by the significant difference between experienced and inexperienced operators. It is advisable to continue the study on more patients in order to obtain a larger data set. It might also be good to consider soft tissue landmarks that are closer to the respective bone tissue ones.

Subjects: ferric and ferrous iron; asbestos; mouse lung

description: Pulmonary toxicity induced by asbestos is thought to be mediated through redox-cycling of fiber-bound and bioavailable iron (Fe).This impacts an oxidative stress which potentially mediates a cascade of events culminating in inflammation, fibrosis and cancer (Ghio et al, 2008 and 2009). The present study aimed to elucidate in a murine model of asbestos exposure the distribution of ferric and ferrous iron and its relation with the development of fibrosis. C57/Bl/6 mice were exposed to saline or crocidolite asbestos in saline (55 and 110 µg intra-tracheally) and examined at 1 and 6 months for lung pathology. The left lung was embedded in paraffin, sectioned and stained with hematoxylin and eosin (H&E) and Masson’s trichrome. A modified Perl’s or Turnbull’s blue histochemical stain was used to demonstrate Fe3+ and Fe2+ respectively (Wang et al, 2002). One month following exposure, mice instilled with crocidolite displayed a significant inflammatory injury on staining with H&E (relative to animal exposed to saline). Crocidolite fibers could be observed most frequently in the region of distal bronchioles. The retention of these fibers was associated with an accumulation of inflammatory cells, predominantly macrophages. This response persisted 6 months following asbestos instillation. Increased collagen was observed at one and 6 months after asbestos exposure. One important observation made in 1-month H&E-stained slides of asbestos-exposed mice was the presence of focal atypical hyperplastic lesions. These lesions did not progress in severity from 1 to 6 months. Histological lung sections from saline exposed mice did not stain for both ferric and ferrous Fe. However, one month following crocidolite instillation, a number of Fe3+-positive (but no Fe2+-positive) cells (predominantly macrophages) were present, in the lower respiratory tract. At 6 months postinjection, an increase number of Fe3+-positive cells was observed and also some Fe2+ positive cells were present. The observation of some Fe2+ positive cells in the lung of asbestos exposed mice at 6 months postinjection suggests a shift in the oxidation state of the accumulated iron, with more cells becoming Fe2+-positive at a late stage. These growing amounts of Fe2+ could support a continuated generation of oxidative stress resulting in clinical manifestations, which culminate in inflammarory, fibrotic and hyperplastic lesions.

description: Time shifting the outputs of Gravitational Wave detectors operating in coincidence is a convenient way to estimate the background in a search for short duration signals. However this procedure is limited as increasing indefinitely the number of time shifts does not provide better estimates. We show that the false alarm rate estimation error saturates with the number of time shifts. In particular, for detectors with very different trigger rates this error saturates at a large value. Explicit computations are done for 2 detectors, and for 3 detectors where the detection statistic relies on the logical ``OR'' of the coincidences of the 3 couples in the network.

description: Diffusion tensor imaging (DTI) could be useful in order to study movement disorders because it is possible to verify variations between several functional circuits simultaneously with a non-invasive approach. Improving DTI method with Constrained Deconvolution System (CDS), it is possible to solve many limitations of this technique. We decided to use CSD approach in order to demonstrate a cerebellar involvement in Parkinson’s Disease (PD), based on hypotheses already made by other authors. Twenty-six patients with PD were studied with a 3 Tesla MRI CSD protocol, with five more control subjects. We obtained Fractional Anisotropy Map (FA) from all patients and we adopted a quantitative analysis of color-signal pixel by pixel. With this method we could study fiber directions of each pixel for each cerebellar slice of each patient. We compared measurements obtained with control subjects. The latter had more red pixels compared to green and blue pixels. PD patients showed less red pixels compared to control subjects. In some cases, green pixels were more than red. This was a clear demonstration of a different colorimetrical signal behavior between PD patients and controls. We advanced the hypothesis that cerebellum undergoes a loss of the ability to analyze and modify informations, because the reduction of red signal (latero-lateral direction) in PD patients, compared to controls, could means that informations may be in transit for less time into reverberating circuits of cerebellar folia.

description: One of the problems in gross anatomy to describe the origin and intracranial course of cranial nerves is we have to remove the brain out of the neurocranium. By this procedure we destroy the subarachnoid cisterns and the relationship to neighbourly structures. The individual anatomy of the specimen provides the basic knowledge for planning the approach. The task of this kind of approach planning is to define the given anatomical spaces between structures, which can be used a pathway. In general for endoscopy we need space and light. That leads us to the old discussion : microsurgical anatomy - endoscopic anatomy - surgical anatomy – systematic anatomy or topographic anatomy à THERE EXISTS ONLY ONE GROSS ANATOMY. For the cranial nerves we use following approaches: 1) supraorbital, 2) transclival, 3) retrosigmoidal and 4) through the foramen magnum. The main anatomical structures seen by endoscopical wiew will be described.

description: Map and compass allow orienteers navigating point to point in unfamiliar and uneven grounds. High levels of fitness and running speed are requested to cover successfully long distances and climbs. Lower limb muscular strength is necessary to sustain challenging descents on rough terrains (Fong et al., 2007). Eight male junior (age, 19±1.6yr) Italian national team orienteers (OR), and 8 cross country track and fields (TF) experienced runners (20±4.5yr), all with right lower limb dominance volunteered. Ages, weights, heights, and BMI of OR and TF did not differ (ANOVA, p>0.05). Each participant performed, and an isokinetic dynamometer measured 5 repetitions of right and left foot dorsal and plantar flexions at the angular speeds of 60-120-180deg/sec respectively. Each value was normalized to the body weight of the respective subject. Descriptive statistics were computed within subject, group, movement, angular speed, and side. For each movement, the effects of group and side on the peak torques at different speeds were compared by ANOVA (statistical significance 5%). On average in both groups, right foot dorsal and plantar flexor muscles were stronger than those of contralateral limb, for all the angular speeds, but no significant differences were found. OR performed peak torques larger than those obtained by TF, in both sides and movements. Differences were significant in foot plantar flexor muscles at 60-120-180deg/sec, and in foot dorsal flexor muscles at 60-120deg/sec (p≤0.04 for all comparisons). The investigation should be extended to a larger group of participants and to other muscular districts. Data could be of interest for athletes, coaches, and physicians to set a correct training planning, to prevent accidental injuries, or to quantify the effects of rehabilitation (Fong et al., 2007).

description: Ball-throwing is a basic open skill common to several physical activities and sports. It is strictly related to eye-hand coordination, a neuromuscular ability affecting many expressions of human movement, including daily living activities (Houwen et al., 2008). The accuracy of underhand ball-throwing task was studied in 538 girls and 583 boys aged 6-11yr, with normal or corrected-to-normal vision. Within range of age, the ages of boys and girls did not differ (ANOVA, p>0.05). Using the dominant hand, each participant performed 2 consecutive sequences of 5 repetitions of a standardized underhand ball-throwing test (UBT). It consisted in underhand throwing a tennis ball into the floor area delimited by a 80cm diameter wooden hoop, lying on the floor 9m apart the standing child (Grassi et al., 2006). Within subject, the centered targets of each sequence were scored. Descriptive statistics of UBT were computed within sequence, age, and sex group. The effects of age and sex, and sex × age interaction on UBT scores were compared by ANOVA (statistical significance 5%). UBT scores significantly increased with age (p=0.003). Boys obtained larger UBT scores than those obtained by the girls of the same age (p=0.002). The age-related differences of UBT scores were similar in boys and girls (p>0.05). On average, UBT scores recorded in the second sequence were larger than those of the first sequence. Differences were significant in boys, and increased with age (p<0.01 for all comparisons). The effects of age was similar in boys and girls (p>0.05). UBT could be used in both sport activities and rehabilitation to quantify either the level of motor learning and training or the effects of physiotherapy treatments.

description: We present progenitor-star detections, light curves, and optical spectra of SN2009ip and the 2009 optical transient in UGC2773 (U2773-OT), which were not genuine SNe. Precursor variability in the decade before outburst indicates that both of the progenitor stars were LBVs. Their pre-outburst light curves resemble the S Doradus phases that preceded giant eruptions of eta Carinae and SN1954J (V12 in NGC2403), with intermediate progenitor luminosities. HST detections a decade before discovery indicate that the SN2009ip and U2773-OT progenitors were supergiants with likely initial masses of 50-80 Msun and $\ga$20 Msun, respectively. Both outbursts had spectra befitting known LBVs, although in different physical states. SN 2009ip exhibited a hot LBV spectrum with characteristic speeds of 550 km/s, plus faster material up to 5000 km/s, resembling the slow Homunculus and fast blast wave of eta Carinae. U2773-OT shows a forest of narrow absorption and emission lines comparable to that of S Dor in its cool state, plus [CaII] emission and an IR excess indicative of dust, similar to SN2008S and N300-OT. [CaII] emission is probably tied to a dusty pre-outburst environment, and not the outburst mechanism. SN2009ip and U2773-OT may provide a critical link between historical LBV eruptions, while U2773-OT may provide a link between LBVs and SN2008S and N300-OT. Future searches will uncover more examples of precursor LBV variability of this kind, providing key clues that may help unravel the instability driving LBVs.

description: We investigate the phase diagram of a two-band frustrated Hubbard model in the framework of dynamical mean field theory. While a first-order phase transition occurs from a paramagnetic (PM) metal to an antiferromagnetic (AF) insulator when both bands are equally frustrated, an intermediate AF metallic phase appears in each band at different $U_c$ values if only one of the two bands is frustrated, resulting in continuous orbital-selective phase transitions from PM metal to AF metal and AF metal to AF insulator. We argue that such intermediate phases are possibly related to the puzzling AF metallic state with small magnetization observed in undoped iron-pnictide superconductors as well as to the pseudogap features observed in optical experiments.
