description: Galactic superwinds occur in almost all infrared-luminous galaxies with star formation rates (SFRs) above 10 M_sun/yr, as shown by studies of the NaI D interstellar absorption line. We demonstrate that this result also applies to ultraluminous infrared galaxies (ULIRGs) which host an active galactic nucleus (AGN) embedded in a strong starburst (SFR > 100 M_sun/yr) by studying a sample of 26 Seyfert ULIRGs in NaI D. The infrared luminosity of these galaxies is powered jointly by the AGN and starburst. We find that there are hints of the influence of the AGN on outflows in Seyfert 2/starburst composites, but the evidence is not yet statistically conclusive. The evidence we find is lower wind detection rates (i.e., wind opening angles) in Seyfert 2 ULIRGs than in galaxies of comparable L_IR, higher velocities than in galaxies of comparable SFR, and correlations between the neutral gas and the ionized gas in the extended narrow-line region. Though the AGN probably contributes to the outflows in Seyfert 2 ULIRGs, its momentum and energy injection is equal to or less than that of the starburst. Similarly, the outflow mechanical luminosity (energy outflow rate) per unit radiative luminosity is the same for starburst and Seyfert 2 ULIRGs. In the nuclei of Seyfert 1s, we observe small-scale outflows that are powered solely by the AGN. However, in Mrk~231, we observe both a high-velocity, small-scale and low-velocity, extended outflow. The latter may be powered by a starburst or radio jet. These large-scale, lower-velocity outflows certainly exist in other Seyfert 1 ULIRGs, but they are washed out by the light of the nucleus.

description: The aim of this study is to investigate the mechanism of electro-acupuncture (EA) on the recovery of injured spinal cord. Rats were randomly divided into normal control, sham-operated, SCI, SCI+EA group and T10 segment spinal cord injury (SCI) rat model was established by the modified Allen’s method. After 7 days, the mRNA and protein expression of Nestin, neuron specific nuclear protein (NeuN) and calcitonin gene related peptide (CGRP) were detected by real time RT-PCR, Western blot and immunohistochemistry respectively. The protein expression of cleaved caspase 3, Bax, Bcl-2, TNF-α and IL-1β were also detected by Western blot. MicroRNA 449a (miR- 449a) expression was also compared. Further, 12 SCI rats were randomly divided into EA and miR subgroups (EA + miR-449a agomir injection). The expression of Nestin, NeuN, CGRP, cleaved caspase 3, Bax, Bcl-2, TNF-α, IL-1β and miR-449a was compared. The direct interaction of miR-449a and CGRP mRNA was assessed by dual luciferase reporter assay. At day 7, compared with sham-operated group, miR-449a expression in SCI group was significantly increased (P < 0.05), and NeuN and CGRP mRNA and protein expression was markedly decreased (P < 0.05), but protein levels of Nestin, cleaved caspase 3, TNF-α, IL-1β and the ratio of Bax/Bcl-2 in SCI group were significantly increased (P < 0.05). The EA treatment significantly reduced miR-449a level and cleaved caspase 3, TNF-α, IL-1β level and the ratio of Bax/Bcl-2 (P < 0.01), but substantially increased Nestin, NeuN and CGRP expression (P < 0.05 or 0.01). High level of iR-449a in miR subgroup was accompanied by decreased expression of Nestin, NeuN and CGRP and increased expression of cleaved caspase 3, TNF-α, IL-1β and elevation of the ratio of Bax/Bcl-2 (P < 0.05), suggesting miR-449a inhibits the effects of EA on NSCs and neurons. Lucif- erase reporter assay showed that miR-449a bound to the 3’ UTR of CGRP, and thereby regulated CGRP expres- sion. In conclusion, EA promotes proliferation of neural stem cells and the survival of neurons by downregulation of miR-449a expression.

description: Ο ναυτιλιακός κλάδος αναμφισβήτητα αποτελεί έναν από τους πιο επικίνδυνους τομείς απασχόλησης. Αυτό συμβαίνει διότι επικρατούν απρόβλεπτες και απαιτητικές συνθήκες εργασίας, όπως και υψηλός κίνδυνος εμφάνισης ατυχημάτων. Παρόλο που υπάρχει σημαντικό ερευνητικό ενδιαφέρον για τους δείκτες υγείας και ευημερίας των εργαζομένων σε διάφορους κλάδους, ελάχιστη προσοχή έχει δοθεί στην εργασιακή επίδοση και προσπάθεια ως εξαρτώμενες μεταβλητές του ωραρίου απασχόλησης. Επίσης, υπάρχει ένα κενό στη διεθνή και εγχώρια βιβλιογραφία που αφορά τα ναυτιλιακά επαγγέλματα. Σκοπός της παρούσας μελέτης είναι η διερεύνηση της σχέσης μεταξύ εργασιακού ωραρίου, εργασιακής προσπάθειας και απόδοσης. Επιπρόσθετοι ερευνητικοί στόχοι είναι η ανάλυση του βαθμού επίδρασης της εργασιακής προσπάθειας στην απόδοση, όπως και των δημογραφικών χαρακτηριστικών στην επιλογή εργασιακού ωραρίου. Για την εκπλήρωση των προαναφερόμενων στόχων διενεργήθηκε ποσοτική έρευνα σε δείγμα διακοσίων εξήντα ενός εργαζομένων του ναυτιλιακού κλάδου της Ελλάδας. Τα αποτελέσματα έδειξαν ότι το εργασιακό ωράριο δεν προδιαθέτει σημαντικά τα επίπεδα εργασιακής προσπάθειας. Επίσης, διαπιστώθηκε πως η βραδινή υπερεργασία για την εκπλήρωση των επαγγελματικών καθηκόντων ενισχύει την αποδοτικότητα του ανθρώπινου δυναμικού. Παράλληλα, αποδείχθηκε ότι η εργασιακή προσπάθεια συσχετίζεται θετικά με την επίδοση των εργαζομένων. Ακόμα, υποστηρίχθηκε ότι τα δημογραφικά χαρακτηριστικά των απασχολούμενων προδιαθέτουν σημαντικά το εργασιακό ωράριο. Συγκεκριμένα, οι άντρες προτιμούν να εργάζονται περισσότερες ώρες ημερησίως και να κάνουν συχνότερα βραδινές υπερωρίες συγκριτικά με τις γυναίκες. Τέλος, προτείνονται μελλοντικές ερευνητικές κατευθύνσεις και στρατηγικές προς τους επαγγελματίες της διοίκησης ανθρώπινου δυναμικού, οι οποίες αποσκοπούν στη βελτίωση της επίδοσης και προσπάθειας των εργαζομένων του ναυτιλιακού κλάδου.

description: Asteroseismology of bright stars has become increasingly important as a method to determine fundamental properties (in particular ages) of stars. The Kepler Space Telescope initiated a revolution by detecting oscillations in more than 500 main-sequence and subgiant stars. However, most Kepler stars are faint, and therefore have limited constraints from independent methods such as long-baseline interferometry. Here, we present the discovery of solar-like oscillations in $α$ Men A, a naked-eye (V=5.1) G7 dwarf in TESS's Southern Continuous Viewing Zone. Using a combination of astrometry, spectroscopy, and asteroseismology, we precisely characterize the solar analog alpha Men A (Teff = 5569 +/- 62 K, R = 0.960 +/- 0.016 Rsun, M = 0.964 +/- 0.045 Msun). To characterize the fully convective M dwarf companion, we derive empirical relations to estimate mass, radius, and temperature given the absolute Gaia magnitude and metallicity, yielding M = 0.169 +/- 0.006, R = 0.19 +/- 0.01 and Teff = 3054 +/- 44 K. Our asteroseismic age of 6.2 +/- 1.4 (stat) +/- 0.6 (sys) Gyr for the primary places $α$ Men B within a small population of M dwarfs with precisely measured ages. We combined multiple ground-based spectroscopy surveys to reveal an activity cycle of 13.1 +/- 1.1 years, a period similar to that observed in the Sun. We used different gyrochronology models with the asteroseismic age to estimate a rotation period of ~30 days for the primary. Alpha Men A is now the closest (d=10pc) solar analog with a precise asteroseismic age from space-based photometry, making it a prime target for next-generation direct imaging missions searching for true Earth analogs.

description: Regional industrialization efforts include industrial recruitment, entrepreneurial and small business development, and business retention and expansion programs. Recently, many states and communities have targeted their industrialization programs at specific industries to promote the development of industry clusters. Broadly defined, an industry cluster is a loose, geographically bounded collection of similar and/or related firms that together create competitive advantages for member firms and the regional economy. The purpose of this paper is to summarize the debate concerning the advisability of industry cluster targeting as an employment generation strategy for states and sub-state regions. Our review of the appropriateness of a clusters strategy begins with a summary of industry cluster characteristics. Next we present the potential advantages developed clusters provide regional economies and the difficulties of establishing competitive clusters in new locations. We conclude with a summary of the implications of an industry clusters strategy for regional industrial development.
Functional analysis of semaphorin-1a in the developing PNS

description: During development, elongating axons must make important steering decisions in order to establish the intricate and precise web of connections in a functional nervous system. Developing axons are currently believed to be guided by cues present in their local environment which act through four general mechanisms: chemoattraction/chemorepulsion (secreted molecules), and contact mediated attraction/contact mediated repulsion (cell surface molecules) which effectively steer the axon growth cone along a directed path to its correct target. The semaphorin family of secreted and cell surface glycoproteins were first described in 1993 and are thought to play an integral role in axon pathfinding by acting as chemorepulsive guidance molecules. However, although chemorepulsion had been demonstrated for several secreted semaphorin family members, little was known about the function of the majority of the semaphorin members, including the transmembrane forms, at the time that this thesis project began in 1995. The aim of this thesis was to investigate the role of Semaphorin-1a, the founding member of the semaphorin family, using the highly accessible peripheral nervous system of the developing grasshopper limb bud with the aspiration of obtaining a better understanding of the functional role of a transmembrane semaphorin. The studies outlined in this thesis investigate the effects of Sema-1a on the pathfinding events of several early arising neurons. The data presented herein describe the first evidence of an attractive guidance activity for a semaphorin family member and highlights the complexity and utility of the semaphorins in axon guidance.

description: We reinvestigate the problem of Gribov ambiguities within the Landau (or Lorentz) gauge for the ghost and gluon propagators in pure SU(2) lattice gauge theory. We make use of the full symmetry group of the action taking into account {\it large}, i.e. non-periodic $\mathbb{Z}(2)$ gauge transformations leaving lattice plaquettes invariant. Enlarging in this way the gauge orbits for any given gauge field configuration the Landau gauge can be fixed at higher local extrema of the gauge functional in comparison with standard (overrelaxation) techniques. This has a clearly visible effect not only for the ghost propagator at small momenta but also for the gluon propagator, in contrast to the common belief.

description: Temporal noise correlations are ubiquitous in quantum systems, yet often neglected in the analysis of quantum circuits due to the complexity required to accurately characterize and model them. Autoregressive moving average (ARMA) models are a well-known technique from time series analysis that model time correlations in data. By identifying the space of completely positive trace reserving (CPTP) quantum operations with a particular matrix manifold, we generalize ARMA models to the space of CPTP maps to parameterize and simulate temporally correlated noise in quantum circuits. This approach, denoted Schrödinger Wave ARMA (SchWARMA), provides a natural path for generalization of classic techniques from signal processing, control theory, and system identification for which ARMA models and linear systems are essential. This enables the broad theory of classical signal processing to be applied to quantum system simulation, characterization, and noise mitigation.

description: Chronic neuropathic pain is a common and widely recognized pain syndrome for patients and difficult to manage for physicians. Azadirachta indica (AI) possesses analgesic, anti-inflammatory, and antioxidant properties. To evaluate the neuroprotective effect of AI standardized extract in an animal model of peripheral neuropathy induced by partial sciatic nerve ligation (PSNL). PSNL was induced in male Wistar rats (180-200 g) with tight ligation of the nerve. Rats received treatment with either vehicle i.e. distilled water (PSNL control), Pyridoxine (100 mg/kg, p.o.) or AI (100, 200 and 400 mg/kg, p.o.) for 28 days. Various behavioral parameters, biochemical, molecular and histological parameters were evaluated. PSNL resulted in a significant decrease (p < 0.05) in allodynia, hy- peralgesia, motor coordination and motor nerve conduction velocity (MNCV) whereas chronic treatment with AI (200 and 400 mg/kg) significantly attenuated (p < 0.05) these behavioral changes. Enhanced activity of oxidative- nitrosative stress, inflammatory mediators (TNF-α, IL-1β, and NF-κB) as well as mRNA expression of Bax, Caspase-3, and iNOs were significantly attenuated (p < 0.05) by AI treatment. It also significantly increased (p < 0.05) peripheral blood oxygen content and Bcl-2 mRNA expression. The flow cytometric analysis revealed that AI (200 and 400 mg/kg) treatment significantly attenuated neural apoptosis and reactive oxygen species levels. PSNL induced histological aberrations were also decreased by AI treatment. Azadirachta indica exerts its neuro- protection against PSNL induced neuropathic pain via inhibition of oxidative-nitrosative stress, the release of pro-inflammatory cytokines and apoptosis to improve MNCV (graphical abstract, Figure 1).

description: The dark matter dominated Fornax dwarf spheroidal has five globular clusters orbiting at ~1 kpc from its centre. In a cuspy CDM halo the globulars would sink to the centre from their current positions within a few Gyrs, presenting a puzzle as to why they survive undigested at the present epoch. We show that a solution to this timing problem is to adopt a cored dark matter halo. We use numerical simulations and analytic calculations to show that, under these conditions, the sinking time becomes many Hubble times; the globulars effectively stall at the dark matter core radius. We conclude that the Fornax dwarf spheroidal has a shallow inner density profile with a core radius constrained by the observed positions of its globular clusters. If the phase space density of the core is primordial then it implies a warm dark matter particle and gives an upper limit to its mass of ~0.5 keV, consistent with that required to significantly alleviate the substructure problem.

description: Lantana camara, the widely studied species, and L. montevidensis, the less studied species of the genus Lantana are both used in traditional medicine for the same purpose (anti-asthma, anti-ulcer, anti-tumor, etc). However, little is known about the toxicity of L. montevidensis and there is limited information on its chemical constituents. Here, we investigated for the first time the genotoxicity and cytotoxicity of the ethanolic (EtOH) and aqueous extracts from the leaves of Lantana montevidensis in human leukocytes, as well as their ossible interaction with human erythrocyte membranes in vitro. The antioxidant activities of both extracts were also investigated in chemical and biological models. Treatment of leukocytes with EtOH or aqueous extracts (1-480 µg/mL) did not affect DNA damage index, but promoted cytotoxicity at higher concentrations (240-480 µg/mL). Both extracts did not modify the osmotic fragility of human erythrocytes. The extracts scavenged DPPH radical and prevented Fe2+-induced lipid peroxidation in rat’s brain and liver homogenates, and this was likely not attributed to Fe (II) chelation. The HPLC analysis of the extracts showed different amounts of polyphenolic compounds (isoquercitrin, gallic acid, catechin, ellagic acid, apigenin, kaempferol, caffeic acid, rutin, quercitrin, quercetin, chlorogenic acid, luteolin) that may have contributed to these effects. These results supported information on the functional use of L. mon-tevidensis in folk medicine.

description: An increased number of tumor-associated macrophages (TAMs) that exhibit the M2 macrophage phenotype is related to poorer prognosis in cancer patients. MafB is a transcription factor regulating the differentiation of macrophages. However, involvement of MafB for the development of TAMs is unknown. This study was designed to investigate the role of MafB in a murine urethane-induced lung cancer model. Urethane was injected intraperitoneally into wild-type and dominant-negative MafB transgenic mice. Twenty-four weeks later, mice were sacrificed and their lungs removed for pathological analysis. The numbers and mean areas of lung cancer were evaluated. In addition, the numbers of Mac-3-positive macrophages were evaluated in each tumor. The numbers and mean areas of lung cancer induced by urethane administration were not significantly different between wild-type and dominant-negative MafB transgenic mice. The numbers of TAMs in lung cancer tissue were not significantly different between the two groups. MafB silencing using dominant-negative MafB did not influence the initiation and growth of lung cancer in mice exposed to urethane. These data suggest that MafB may not be related to the development of TAMs.

description: This research uses simulated test marketing methodology to examine the consumer purchase interest in organic grapes and price sensitivity. A profile of the target organic food purchaser is identified and consumer perceptions of organic grapes are compared to their perceptions of regular (conventionally grown) grapes. The research uses a survey instrument and a concept exposure that were administered through the use of a personal interview of 342 randomly selected respondents at food stores in May 2001 in San Luis Obispo County, California. Comparisons of nominal and ordinal variables were generated through the use of chi-square tests. The statistical tests used to examine interval and ratio variables are t-tests, one-way analysis of variance, and multivariate analysis of variance.

description: The PII protein family constitutes one of the most conserved and well distributed family of signal transduction proteins in nature. These proteins play key roles in nitrogen and carbon metabolism. PII function has been well documented in Gram-negative bacteria. However, there are very few reports describing the in vitro properties and function of PII derived from Gram-positive bacteria. Here we present the heterologous expression and efficient purification protocols for untagged PII from three Actinobacteria of medical and biotechnological interest namely: Mycobacterium tuberculosis, Rhodococcus jostii and Streptomyces coelicolor. Circular dichroism and gel filtration analysis supported that the purified proteins are correctly folded. The purification protocol described here will facilitate biochemical studies and help to uncover the biochemical functions of PII proteins in Actinobacteria.

description: Obesity is one of the diagnostic criteria of metabolic syndrome (MS). It is correlated with insulin resistance (IR) and high vascular risk as well. Advanced glycation end products (AGEs) and their receptor (RAGE) play an important role in abnormal metabolic components in obese women. This study aimed to explore the serum levels of sRAGE in Egyptian obese women and compare with healthy non-obese controls and investigate the relationship between serum sRAGE, metabolic parameters, and obesity complications. The soluble form of receptor for advanced glycation end products (sRAGE), anthropometry, metabolic and biochemical biomarkers were measured in 100 obese women and 100 age-matched healthy control non-obese women. The homeostasis model assessment estimate of insulin resistance (HOMA-IR) has been determined from serum insulin and glucose values. Serum sRAGE levels were significantly lower in obese cases than controls and inversely correlated with obesity and metabolic parameters. Results of univariate and multivariate analyses for determinants of serum sRAGE levels in obese cases showed that parameters statistically and significantly related were body mass index (BMI), waist circumference (WC), LDL-C, TG, BP, HOMA-IR, ALT and AST. sRAGE is a novel biomarker for metabolic dysfunction in Egyptian obese women and might predict the future cardio-metabolic events.

description: The X-ray spectrum of extreme HBL type blazars is located in the synchrotron branch of the broadband spectral energy distribution (SED), at energies below the peak. A joint fit of the extrapolated X-ray spectra together with a host galaxy template allows characterizing the synchrotron branch in the SED. The X-ray spectrum is usually characterized either with a pure or a curved power-law model. In the latter case, however, it is hard to distinguish an intrinsic curvature from excess absorption. In this paper, we focus on five well-observed blazars: 1ES 0229+200, PKS 0548-322, RX J1136+6737, 1ES 1741+196, 1ES 2344+514. We constrain the infrared-to-X-ray emission of these five blazars using a model that is characterized by the host galaxy, spectral curvature, absorption, and ultraviolet excess to separate these spectral features. In the case of four sources: 1ES 0229+200, PKS 0548-322, 1ES 1741+196, 1ES 2344+514 the spectral fit with the atomic neutral hydrogen from the Leiden Argentina Bonn Survey result in a significant UV excess present in the broadband spectral energy distribution. Such excess can be interpreted as an additional component, for example, a blue bump. However, in order to describe spectra of these blazars without such excess, additional absorption to the atomic neutral hydrogen from the Leiden Argentina Bonn Survey is needed.

description: Αυτή η μελέτη εξετάζει τον αντίκτυπο της σταθερής αγοράς στην περιβαλλοντική, κοινωνική και διακυβερνητική (ESG) απόδοση της εταιρείας. Χρησιμοποιούμε μια συγκριτική ανάλυση του προφίλ της απόδοσης ESG μεταξύ νέων και εδραιωμένων εταιρειών στην αγορά, ελέγχοντας τη δυναμική της αγοράς και συγκεκριμένα χαρακτηριστικά των εταιρειών. Η εμπειρική μας ανάλυση βασίζεται σε ετήσια χρηματοοικονομικά δεδομένα και τις τιμές αγοράς για 1940 εισηγμένες εταιρείες των ΗΠΑ από το 2007 έως το 2016. Επικεντρωνόμαστε στη σχέση μεταξύ της βιωσιμότητας και της ηλικίας των επιχειρήσεων δοκιμάζοντας τον αντίκτυπο της ηλικίας των επιχειρήσεων στην απόδοση ως προς την ESG των εταιρειών. Επιπλέον, δοκιμάζουμε αυτήν την υπόθεση σε περιόδους κρίσης. Διαπιστώνουμε ότι οι παλαιότερες εταιρείες έχουν σημαντικά χαμηλότερη απόδοση στη βιωσιμότητα σε σύγκριση με τις νεότερες. Τα αποτελέσματά μας δείχνουν ότι οι νεότερες εταιρείες μπορούν να προσαρμοστούν πιο αποτελεσματικά στις σύγχρονες βιώσιμες επιχειρηματικές απαιτήσεις.

description: Η παρούσα διπλωματική παρουσιάζει ένα μοντέλο πλέγματος, αποτίμησης δικαιωμάτων προαίρεσης μέσω της κατασκευής τεκμαρτού τριωνυμικού δέντρου. Βασικός σκοπός είναι να κατασκευαστεί ένα μοντέλο μέσω του οποίου θα ενσωματώνεται η πληροφορία της τεκμαρτής μεταβλητότητας και θα το καθιστά πιο ακριβές στην αποτίμηση δικαιωμάτων προαίρεσης. Αρχικά, παρουσιάζεται μια σύντομη ιστορική αναδρομή για την ανάγκη εύρεσης ενός πιο αποδοτικού μοντέλου αποτίμησης δικαιωμάτων προαίρεσης, και αναλύεται το πρόβλημα που δημιουργείται με την χρήση της σταθερής μεταβλητότητας σε προϋπάρχοντα μοντέλα. Ακολουθεί η θεωρητική ανάλυση ξεκινώντας από το απλό διωνυμικό μοντέλο αποτίμησης συνεχίζοντας με το απλό τριωνυμικό μοντέλο ως ένα διωνυμικό δυο βημάτων, και φτάνοντας στην κατασκευή ενός τεκμαρτού τριωνυμικού δέντρου για την αποτίμηση Ευρωπαϊκών δικαιωμάτων αγοράς και πώλησης. Με βάση την θεωρητική ανάλυση δημιουργούνται οι κατάλληλοι αλγόριθμοι για να γίνει η εμπειρική μελέτη στο μοντέλο. Για ένα δείγμα ιστορικών ημερών συλλέγονται τα διαθέσιμα δικαιώματα προαίρεσης, εκτιμάται η τεκμαρτή μεταβλητότητα και δημιουργείται το τεκμαρτό τριωνυμικό δέντρο. Αποτιμώντας τα δικαιώματα του δείγματος με τα παραπάνω μοντέλα, συμπεραίνουμε ότι το τελευταίο πρόκειται για ένα πιο ευέλικτο και αποτελεσματικό μοντέλο αποτίμησης των Ευρωπαϊκών δικαιωμάτων αγοράς και πώλησης. Επίσης, μπορεί να επεκταθεί και στην αποτίμηση δικαιωμάτων Αμερικανικού τύπου καθώς κατασκευάζεται σε διακριτό χρόνο.

description: This paper develops a statistically unbiased and simple method for measuring the difference of independent empirical distributions estimated by bootstrapping or other simulation approaches. This complete combinatorial method is compared with other unbiased and biased methods that have been suggested in the literature, first in Monte Carlo simulations and then in a field test of external and internal scope testing in contingent valuation. Tradeoffs between methods are discussed. When the empirical distributions are not independent a straightforward difference test is suggested.

description: A novel series of 1,3,5-trisubstituted-2-pyrazoline derivatives (PFC-1 to PFC-16) were synthesized in a three step reaction using conventional and microwave assisted green chemistry approach. The synthesized derivatives were characterized and their chemical structures were established by various physicochemical methods such as IR, Mass, 1H-NMR, 13C-NMR and elemental analysis. The synthesized compounds were tested for their neurophar- macological potential. The compounds exhibited significant antidepressant and anti-anxiety activities against var- ious behavioral in vivo models. Compounds PFC-3 and PFC-12 were found to be the most active derivatives in the series. The 2-pyrazoline analogs, having 2-hydroxyphenyl and anthracen-9-yl substitution at 3rd position while 4-benzyloxyphenyl and 4-methylphenyl substitution at 5th position, were decisive in eliciting good antidepressant and anxiolytic properties, respectively. The docking experiments revealed that the synthesized derivatives were potential inhibitors of MAO-A protein, which plays a central role in managing depression and anxiety disorders. The most potent derivatives were found to be involved in some key interactions with Tyr407, Tyr444, Phe352 and Ala68 amino acid residues at the binding site of MAO-A protein. All the synthesized derivatives successfully passed the pharmacokinetic barriers of absorption, distribution, metabolism and elimination as predicted using in silico techniques without showing any substantial indication of acute and neurotoxicity. This was further confirmed in the laboratory by performing acute toxicity studies as per OECD guidelines.

A bridge between the minimal doubly resolving set problem in (folded) hypercubes and the coin weighing problem

description: In this paper, we consider the minimal doubly resolving set problem in Hamming graphs, hypercubes and folded hypercubes. We prove that the minimal doubly resolving set problem in hypercubes is equivalent to the coin weighing problem. Then we answer an open question on the minimal doubly resolving set problem in hypercubes. We disprove a conjecture on the metric dimension problem in folded hypercubes and give some asymptotic results for the metric dimension and the minimal doubly resolving set problems in Hamming graphs and folded hypercubes by establishing connections between these problems. Using the Lindström's method for the coin weighing problem, we give an efficient algorithm for the minimal doubly resolving set problem in hypercubes and report some new upper bounds. We also prove that the minimal doubly resolving set problem is NP-hard even restrict on split graphs, bipartite graphs and co-bipartite graphs.

description: Using hydrodynamic simulations and a technique to extract the rotational component of the velocity field, we show how bubbles of relativistic gas inflated by AGN jets in galaxy clusters act as a catalyst, transforming the energy carried by sound and shock waves to heat. The energy is stored in a vortex field around the bubbles which can subsequently be dissipated. The efficiency of this process is set mainly by the fraction of the cluster volume filled by (sub-)kpc scale filaments and bubbles of relativistic plasma.

description: A growing trend in demand analysis during the last two decades is the use of household survey data. Detailed demographic information collected in these surveys allows treatment of heterogeneous preference and the typically large sample also allows estimation of large demand system that are otherwise not possible with aggregate time series. However, the use of household-level data is complicated by the censoring of the dependent variable especially for systems with disaggregated commodity definitions. To overcome the numerical problem of evaluating truncated multi-dimensional error term distributions, a Quasi-maximum likelihood method is used to estimate a censored 9-commodity demand system for a sample of urban Mexican households. The impacts of changes in price and expenditures are quantified as are the impacts of alternative household compositions evaluated via the use of an endogenously determined equivalence scale.

An oscillation result is used to prove hitherto unknown almost everywhere convergence for the signed average analog of Bourgain's averages. As an immediate corollary we obtain a Wiener-Wintner type of result for the ergodic Hilbert series.

description: Using a unique dataset on the characteristics, origin, and destination of households who engaged in intrametropolitan moves in the Columbus, Ohio area, we estimate a hybrid conditional logit choice model of residential location that separately identifies the push/pull influence of local public goods, namely school quality and public safety, from household income and other lifecycle effects. Our results provide evidence of both a "natural evolution" of households, due to income and household structural changes, as well as a "flight from blight", due to higher crime rates, lower school quality, and lower quality of housing stock in the central city. In comparing the magnitudes of these variables, we find that the influence of public school quality is consistently larger than the influence of household income across all locations and particularly in the central city. Rather than being largely a result of the "natural evolution" of households as incomes grow over time, our results provide evidence that the central city's inferior public goods, most notably school quality, have played a much more dominant role in pushing households to suburban locations. This finding has important implications for central city, suburban, and exurban communities that seek to counteract the movement of population to the outer suburbs and beyond.
