description: Οι σύγχρονες εφοδιαστικές αλυσίδες καλούνται να ανασχεδιάσουν τις διαδικασίες
τους προκειμένου αυτές να εναρμονιστούν με τους περιβαλλοντικούς στόχους που πολλές χώρες έχουν θέσει για το εγγύς μέλλον. Ειδικότερα, στον τομέα των αστικών και περιαστικών μεταφορών, η μετάβαση στην ηλεκτροκίνηση αναμένεται να αναβαθμίσει σημαντικά την ποιότητα ζωής των κατοίκων των πόλεων. Ένας τύπος ηλεκτρικού οχήματος που έχει τη δυνατότητα να αλλάξει άρδην τις αστικές μεταφορές είναι τα Μη Στελεχωμένα Εναέρια Οχήματα (Unmanned Aerial Vehicles - UAV ), γνωστά ως «drones».
Η παρούσα διδακτορική διατριβή πραγματεύεται τη χρήση των UAV σε προβλήματα
δρομολόγησης οχημάτων που αφορούν ανθρωπιστικές και εμπορικές εφαρμογές. Συγκεκριμένα, μοντελοποιεί και επιλύει δύο προβλήματα όπου τα UAV χρησιμοποιούνται σε αποστολές έρευνας και διάσωσης, και δύο προβλήματα που αφορούν τη χρήση τους για τη μεταφορά εμπορευμάτων στον αστικό ιστό πόλεων.
Αρχικά παρουσιάζεται το Συσσωρευτικό Πρόβλημα Δρομολόγησης UAV που έχει
εφαρμογή σε αποστολές έρευνας και διάσωσης. Οι αποστολές αυτές αποτελούν προβλήματα ελαχιστοποίησης του χρόνου που απαιτείται για την κάλυψη μιας περιοχής ενδιαφέροντος. Η προτεινόμενη μεθοδολογία μετατρέπει το πρόβλημα κάλυψης σε ένα πρόβλημα δρομολόγησης UAV, ενσωματώνοντας σε αυτό τον αντικειμενικό στόχο της αποστολής και τους περιορισμούς που διέπουν την αυτονομία των UAV. Το δεύτερο πρόβλημα που προτείνεται για τη μοντελοποίηση σεναρίων έρευνας, είναι το Πρόβλημα Αναζήτησης Κινούμενων Κορυφών με UAV. Σε αυτό λαμβάνεται υπόψη η κίνηση των αγνοουμένων εντός της περιοχής ενδιαφέροντος, επομένως αποτελεί ένα δυναμικό πρόβλημα βελτιστοποίησης. Στόχος του προβλήματος είναι η μεγιστοποίηση της αξίας των σημείων που καλύπτουν UAV, για το σύνολο του χρόνου που διαρκεί η έρευνα.
Στη συνέχεια παρουσιάζεται το Πρόβλημα Δρομολόγησης συνδυασμού Ηλεκτρικών
Οχημάτων Δρόμου και UAV, όπου αφορά εμπορικές εφαρμογές, με τους δύο τύπους
ηλεκτρικών οχημάτων να λειτουργούν συνεργατικά προκειμένου να παρακάμψουν τις
αδυναμίες τους και να προσφέρουν τα πλεονεκτήματά τους. Στόχος του προβλήματος
είναι η ελαχιστοποίηση της συνολικά καταναλισκόμενης ενέργειας που απαιτείται για την παράδοση δεμάτων. Το δεύτερο πρόβλημα που προτείνεται σε αυτή την κατηγορία είναι το Πρόβλημα Ελαχιστοποίησης Ενέργειας Δρομολόγησης UAV με Παραλαβές και Παραδόσεις. Σε αυτό μοντελοποιούνται υπηρεσίες ταχυμεταφορών με χρήση UAV μεταξύ ιδιωτών και έχει εφαρμογή σε αγοραπωλησίες μέσω των μέσων κοινωνικής δικτύωσης. Στόχος είναι η ελαχιστοποίηση της ενέργειας που απαιτείται για την εκτέλεση του μεταφορικού έργου.

Loria’s Free-tailed Bat Ozimops loriae French: Tadaride de Loria / German: Loria-Bulldogfledermaus / Spanish: Murciélago rabudo de Loria Other common names: Loria’s Mastiff Bat, Little Northern Mastiff Bat Taxonomy. Nyctinomus loriae Thomas, 1897, “Kamali,” close to the mouth of the Kemp Welch River, Papua New Guinea. As currently defined, Ozimops loriae is confined to Papua New Guinea after its former races cobourgianus and ride: were elevated to species level. It was included in the novel subgenus Ozimops, elevated to genus level by S. M. Jackson and C. P. Groves in 2015. Monotypic. Distribution. Known only from a few locations in SE coastal Papua New Guinea, in and around the National Capital District, Port Moresby, and Central Province. Descriptive notes. Head-body 48-50 mm, tail 27 mm, ear 11 mm, hindfoot 5- 3-8 mm, forearm 32-34 mm; weight 6-13 g. Loria’s Free-tailed Bat is the smallest free-tailed bat in Papua New Guinea. Fur is pale gray brown, paler on underside. Upperlip is wrinkled. Wings are long, narrow, and tapered and black brown. Ears are not joined by a membrane, and are triangular with smooth margins. Adult males have a gular pouch. Habitat. Known only from.low-elevation savanna woodlands between sea level and 100 m, including the urban settlements of Port Moresby. Food and Feeding. Loria’s Free-tailed Bat probably forages for flying insects in open areas or above the forest canopy. Based on wing morphology, flight is presumed to be direct and fast, with limited maneuverability. Breeding. No information. Activity patterns. Loria’s Free-tailed Bats have been reported roosting in hollows in Eucalyptus (Myrtaceae) trees. Movements, Home range and Social organization. The Australian Museum has nine Loria’s Free-tailed Bat specimens collected from a single roost in a tree hollow, at Laloki in Central Province, Papua New Guinea. The roost contained at least nine individuals of mixed sexes. Status and Conservation. Classified as Data Deficient on The IUCN Red List (as Mormopterus loriae), because there is insufficient information on the species’ range and population size (both of which appear very small), or on possible threats.

description: Geometrical coupling in a co-dimensional one Randall-Sundrum scenario (RS) is used to study resonances of $p-$form fields. The resonances are calculated using the transfer matrix method. The model studied consider the standard RS with delta-like branes, and branes generated by kinks and domain-wall as well. The parameters are changed to control the thickness of the smooth brane. With this a very interesting pattern is found for the resonances. The geometrical coupling does not generate resonances for the reduced $p-$form in all cases considered.

description: We provide a systematic treatment of chemical equilibrium in the presence of a specific type of time dependent background. The type of time dependent background we consider appears, for example, in recently proposed axion/Majoron leptogenesis models [1,2]. In describing the chemical equilibrium we use quantities which are invariant under redefinition of fermion phases (we refer to this redefinition as a change of basis for short), and therefore it is a basis invariant treatment. The change of the anomaly terms due to the change of the path integral measure [3,4] under a basis change is taken into account. We find it is useful to go back and forth between different bases, and there are insights which can be more easily obtained in one basis rather than another. A toy model is provided to illustrate the ideas. For the axion leptogenesis model [1], our result suggests that at $T > 10^{13}$ GeV , when sphaleron processes decouple, and $Γ_{B+L} << H < Γ_L$ (where $H$ is the Hubble parameter at temperature $T$ and $Γ_L$ is the $ΔL = 2$ lepton number violating interaction rate), the amount of $B-L$ created is controlled by the smallness of the sphaleron interaction rate, $Γ_{B+L}$. Therefore it is not as efficient as described. In addition, we notice an interesting modification of gauge boson dispersion relations at subleading order.

description: We compute corrections to the inflationary potential due to conformally coupled non-relativistic matter. We find that under certain conditions of the matter coupling, inflation may be interrupted abruptly. We display this in the superconformal Starobinsky model, where matter is conformally coupled to the Einstein frame metric. These corrections may easily stop inflation provided that there is an initial density of non-relativistic matter. Since these additional heavy degrees of freedom generically occur in higher dimension theories, for example as Kaluza-Klein modes, this effect can arise in multiple scenarios.

South-western Free-tailed Bat Ozimops kitcheneri French: Tadaride de Kitchener / German: Stdwestliche Bulldogfledermaus / Spanish: Murciélago rabudo de Kitchener Other common names: Western Free-tailed Bat, Western Mastiff Bat Taxonomy. Mormopterus (Ozimops) kitcheneri McKenzie, Reardon & Adams in Reardon et al., 2014, “ 20 km north-west of Balladonia, Western Australia. 32.252°S, 123.431°E.” Ozimops kitchener: was previously synonymized with O. planiceps. It was identified as a distinct taxon (“species 4 population O”) by M. Adams and colleagues in 1988, and informally known by that identity until formally described by T. B. Reardon and colleagues in 2014 and placed in the Mormopterus subgenus Ozimops. Ozimops was then elevated to genuslevel by S. M.Jackson and C. P. Groves in 2015. Monotypic. Distribution. Restricted to S Western Australia. Descriptive notes. Head-body 55-60 mm, tail 28-36 mm, forearm 33-35 mm; weight 8-10- 5 g. Fur on head and back is gray or brown with pale bases; lighter on underside. Ears are triangular. Skin on ears, wings, and muzzle is dark brown. Males are distinguishable from all other Ozimops species by having a penis thatis shorter than 7- 5 mm but with pointed bacular mound. Skull is very flat. The species can be distinguished from other Ozimops by a unique combination of allozyme alleles with number offixed differences ranging from two to ten. Habitat. Semiarid and mesic eucalypt forests and woodlands. Food and Feeding. South-western Free-tailed Bats hunt flying insects above the canopy, taking them in high-speed passes at ¢. 25-30 km /h. Breeding. Females give birth to single young during early summer (December). Activity patterns. South-western Free-tailed Bats usually roost in tree hollows, although small colonies have been found in the roofs of buildings. Movements, Home range and Social organization. South-western Free-tailed Bats are colonial. Status and Conservation. Classified as Least Concern on The IUCN Red List (as Mormopterus kitcheneri), due to its very large range (c. 350,000 km?) and area of occupancy (not estimated). The South-western Free-tailed Bat uses a broad range of habitats and is common in suitable habitat, so is presumed to have a large population size. There are no data on population trends forthis species, but a significant reduction in population size since colonial expansion from the late 1800s can be inferred from land clearing data.

description: Free space optical (FSO) communication has been receiving increasing attention in recent years with its ability to achieve ultra-high data rates over unlicensed optical spectrum. A major performance limiting factor in FSO systems is atmospheric turbulence which severely degrades the system performance. To address this issue, multiple transmit and/or receive apertures can be employed, and the performance can be improved via diversity gain. In this paper, we investigate the bit error rate (BER) performance of FSO systems with transmit diversity or receive diversity with equal gain combining (EGC) over atmospheric turbulence channels described by the Double Generalized Gamma (Double GG) distribution. The Double GG distribution, recently proposed, generalizes many existing turbulence models in a closed-form expression and covers all turbulence conditions. Since the distribution function of a sum of Double GG random variables (RVs) appears in BER expression, we first derive a closed-form upper bound for the distribution of the sum of Double GG distributed RVs. A novel union upper bound for the average BER as well as corresponding asymptotic expression is then derived and evaluated in terms of Meijer's G-functions.

description: This study presents a piezoelectric energy harvester made of poly(vinylidene fluoride-trifluoroethylene)/polyethylene terephthalate for use in structural health monitoring applications. The piezoelectric energy harvester was made of a layer of polyvinylidene fluoride-trifluoroethylene (PVDF/TrFE). In addition, PET sheets, double-sided micron-thick tapes, and PVDF-TrFE sheets were utilized in the fabrication of the device. The proposed device was characterized by measuring its output voltage and current. The output power of the harvester was sufficient to operate a MEMS pressure sensor under wind pressure, with a maximum current of 291.34 µA and a maximum voltage of 937.01 mV. The power value obtained was 272.99 µW.

description: We present an update of the CLUMPY code for the calculation of the astrophysical J-factors (from dark matter annihilation/decay) for any Galactic or extragalactic dark matter halo including substructures: halo-to-halo concentration scatter may now be enabled, boost factors can include several levels of substructures, and triaxiality is a new option for dark matter haloes. This new version takes advantage of the CFITSIO and HEALPix libraries to propose FITS output maps using the HEALPix pixelisation scheme. Skymaps for $γ$-ray and $ν$ signals from generic annihilation/decay spectra are now direct outputs of CLUMPY. Making use of HEALPix routines, smoothing by a user-defined instrumental Gaussian beam and computing the angular power spectrum of the maps is now possible. In addition to these improvements, the main novelty is the implementation of a Jeans analysis module, to obtain dark matter density profiles from kinematic data in relaxed spherical systems (e.g., dwarf spheroidal galaxies). The code is also interfaced with the GreAT toolkit designed for Markov Chain Monte Carlo analyses, from which probability density functions and credible intervals can be obtained for velocity dispersions, dark matter profiles, and J-factors.

Prestellar Core Formation, Evolution, and Accretion from Gravitational Fragmentation in Turbulent Converging Flows

Publisher: name: arXiv
Year: 2015
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: We investigate prestellar core formation and accretion based on three-dimensional hydrodynamic simulations. Our simulations represent local $\sim 1$pc regions within giant molecular clouds where a supersonic turbulent flow converges, triggering star formation in the post-shock layer. We include turbulence and self-gravity, applying sink particle techniques, and explore a range of inflow Mach number ${\cal M}=2-16$. Two sets of cores are identified and compared: $t_1$-cores are identified of a time snapshot in each simulation, representing dense structures in a single cloud map; $t_\mathrm{coll}$-cores are identified at their individual time of collapse, representing the initial mass reservoir for accretion. We find that cores and filaments form and evolve at the same time. At the stage of core collapse, there is a well-defined, converged characteristic mass for isothermal fragmentation that is comparable to the critical Bonner-Ebert mass at the post-shock pressure. The core mass functions (CMFs) of $t_\mathrm{coll}$-cores show a deficit of high-mass cores ($\gtrsim 7M_\odot$) compared to the observed stellar initial mass function (IMF). However, the CMFs of $t_1$-cores are similar to the observed CMFs and include many low-mass cores that are gravitationally stable. The difference between $t_1$-cores and $t_\mathrm{coll}$-cores suggests that the full sample from observed CMFs may not evolve into protostars. Individual sink particles accrete at a roughly constant rate throughout the simulations, gaining one $t_\mathrm{coll}$-core mass per free-fall time even after the initial mass reservoir is accreted. High-mass sinks gain proportionally more mass at late times than low-mass sinks. There are outbursts in accretion rates, resulting from clumpy density structures falling into the sinks.

description: In this paper, a modified Eddington-inspired-Born-Infeld (EiBI) theory with a pure trace term $g_{μν}R$ being added to the determinantal action is analysed from a cosmological point of view. It corresponds to the most general action constructed from a rank two tensor that contains up to first order terms in curvature. This term can equally be seen as a conformal factor multiplying the metric $g_{μν}$. This very interesting type of amendment has not been considered within the Palatini formalism despite the large amount of works on the Born-Infeld-inspired theory of gravity. This model can provide smooth bouncing solutions which were not allowed in the EiBI model for the same EiBI coupling. Most interestingly, for a radiation filled universe there are some regions of the parameter space that can naturally lead to a de Sitter inflationary stage without the need of any exotic matter field. Finally, in this model we discover a new type of cosmic "quasi-sudden" singularity, where the cosmic time derivative of the Hubble rate becomes very large but finite at a finite cosmic time.

description: The article considers the Derrida-Retaux model with a random number of terms, i.e. a sequence of integer random variables defined by the relations $ X_{n + 1} = (X_n^{(1)} + X_n^{(2)} + ... + X_n^{(N_n)} - a)^{+}$, $n\ge 0$, where $X_n^{j}$ are independent copies of $X_n$, the values of $N_j$ are independent and identically distributed, $a$ is a positive integer. The energy in the model is defined as $Q:=\lim\limits_{n\to\infty} \frac{\mathbb{E}(X_{n})}{(\mathbb{E}N_1)^{n}}$. We present sufficient conditions (in terms of distributions of $X_0$ and $N_1$) for subcritical ($Q=0$) and supercritical ($Q>0$) regimes of model behavior.

description: We present a few newly found old sunspot observations from the years AD 1708, 1709, and 1710, which were obtained by Peter Becker from Rostock, Germany. For 1709, Becker gave a detailed drawing: he observed a sunspot group made up of two spots on Jan 5, 6, and 7, and just one of the two spots was observed on Jan 8 and 9. We present his drawing and his explanatory text. We can measure the latitude and longitude of these two spots and estimate their sizes for all five days. While the spots and groups in 1708 and the spot on four of the five days in January 1709 were known before from other observers (e.g. Hoyt & Schatten 1998), the location of the spots in early January 1709 were not known before, so that they can now be considered in reconstructed butterfly diagrams. The sunspots detected by Becker on 1709 Jan 5 and 1710 Sep 10 were not known before at all, as the only observer known for those two dates, La Hire, did not detect that spot (group). We estimate new group sunspot numbers for the relevant days, months, and years. The time around 1708--1710 is important, because it documents the recovery of solar activity towards the end of the Maunder Grand Minimum. We also show two new spot observations from G. Kirch for 1708 Sep 13 \& 14 as described in his letter to Wurzelbaur (dated Berlin AD 1708 Dec 19).

description: We present Atacama Large Millimeter/submillimeter Array observations of 99.02 GHz free-free and H40$α$ emission from the centre of the nearby starburst galaxy NGC 253. We calculate electron temperatures of 3700-4500 K for the photoionized gas, which agrees with previous measurements. We measure a photoionizing photon production rate of $(3.2\pm0.2)\times10^{53}$ s$^{-1}$ and a star formation rate of $1.73\pm0.12$ M$_\odot$ yr$^{-1}$ within the central 20$\times$10 arcsec, which fall within the broad range of measurements from previous millimetre and radio observations but which are better constrained. We also demonstrate that the dust opacities are ~3 dex higher than inferred from previous near-infrared data, which illustrates the benefits of using millimetre star formation tracers in very dusty sources.

Publisher: name: Zenodo
Year: 2021

description: This research presents the numerical investigation of the dynamic response of bus structure by optimizing the frame size. The study is very important to fill the gap in the area of vehicle structure response due to maneuverability. Here it is aimed to optimize the weight of bus body structure by evaluating its stress and deformation. The study worked at Bishoftu bus model ZK6118HGA, modeled with solid work 18 and analysis has been done with ANSYS 19.0. Braking left corner, and right cornering test has been performed. Optimization has been done by replacing overdesigned RHS (rectangular hollow section) with lower-sized RHS. The improved structure was also investigated with the cornering and braking tests. The weight of the improved structure is significantly lower than the original structure. The study revealed that the weight of the bus body structure was reduced by 93.58 kg. Which is about 3.07% of the whole structure weight. The procedure used for the analysis is validated using analytical calculations on simply supported overhanging beam comparing to software verification.

description: In a piece published in 1981, H. M. Edwards touts the benefits of reading the masters. A quarter-century later, Edwards takes seriously his own advice by publishing an encomium on Euler's Institutiones (1755). While we agree with Edwards that we shall all do well by studying the masters, we argue that to derive the full benefit, one must read historically important texts without interposing a lens formed by one's own mathematical accomplishments. We show, in particular, that Edwards misses much of the style and substance of Euler's Institutiones by reading the text through a constructivist lens.

description: This paper considers the problem of estimating the delays of a weighted superposition of pulses, called stream of pulses, in a noisy environment. We show that the delays can be estimated using a tractable convex optimization problem with a localization error proportional to the square root of the noise level. Furthermore, all false detections produced by the algorithm have small amplitudes. Numerical and in-vitro ultrasound experiments corroborate the theoretical results and demonstrate their applicability for the ultrasound imaging signal processing.
PEER SOCIALIZATION OF NONSUICIDAL SELF-INJURY (NSSI):  MODERATORS OF THE ASSOCIATION BETWEEN PEER GROUP NSSI AND FUTURE SELF-INJURIOUS BEHAVIOR

description: Nonsuicidal self-injury (NSSI) is a remarkably prevalent behavior among adolescents, yet few robust longitudinal predictors have been identified.  Prior work suggests that adolescents’ friends’ engagement in NSSI is a potent prospective predictor of adolescents’ own increased engagement in NSSI.  Given adolescents’ heightened sensitivity to social rewards and under-developed inhibitory control, these peer socialization effects may represent a powerful risk, perhaps especially among adolescents experiencing internalizing symptoms and interpersonal distress.  Additionally, peers’ favorable responses to NSSI may provide social reinforcement among adolescents who engage in self-injurious thoughts and behaviors.  This large scale, two-wave longitudinal study offered a unique opportunity to examine peer socialization effects in broader groups of friends in a school-based sample of adolescents.  Utilizing three distinct metrics for friend NSSI behaviors in larger groups, unique conceptualizations of how peer socialization occurs dynamically among friends were examined.  Findings implicate peer socialization of NSSI as a dynamic, bi-directional phenomenon during adolescence under unique conditions of interpersonal and internalizing symptoms.

description: We use the recently derived density of states for a particle confined to a spherical well in three dimensional fuzzy space to compute the thermodynamics of a gas of non-interacting fermions confined to such a well. Special emphasis is placed on non-commutative effects and in particular non-commutative corrections to the thermodynamics at low densities and temperatures are computed where the non-relativistic approximation used here is valid. Non-commutative effects at high densities are also identified, the most prominent being the existence of a minimal volume at which the gas becomes incompressible. The latter is closely related to a low/high density duality exhibited by these systems, which in turn is a manifestation of an infra-red/ultra violet duality in the single particle spectrum. Both non-rotating and slowly rotating gasses are studied. Approximations are benchmarked against exact numerical computations for the non-rotating case and several other properties of the gas are demonstrated with numerical computations. Finally, a non-commutative gas confined by gravity is studied and several novel features regarding the mass-radius relation, density and entropy are highlighted.

Creators: name: Sussman, Alexandra
Publisher: name: No Publisher Supplied
Year: 2022

description: Purpose of Project: The purpose of this DNP project was to conduct a gap analysis to understand the differences between current practice and evidence-based recommendations and to develop a tailored toolkit for healthcare providers to optimize pharmacological management of older adults.Methodology: Using a gap analysis methodology, healthcare providers from four suburban offices in New Jersey participated in a nine-question electronic survey to assess current practices of polypharmacy management. A gap analysis was performed and a toolkit consisting of useful resources was developed to address the identified gaps. Results: Fifteen participants successfully completed the survey. Although the majority of healthcare providers maintain several good practices regarding polypharmacy management, less than half (40%) of them use specific evidence-based screening tools to identify high-risk medications on a routine basis. Consistent with prior research, this DNP project demonstrates healthcare providers underutilize evidence-based recommendations and screening tools when managing polypharmacy in older adults.Implications for Practice: Utilization of an evidence-based toolkit may improve healthcare providers’ polypharmacy management and deprescribing practices. Furthermore, a consistent approach to polypharmacy management may improve medication quality and safety resulting in overall improved patient outcomes.
Improving nursing home cascade communication for quality measures

description: Purpose of Project: Improve cascade communication for quality measures in frontline nursing home (NH) staff using evidence-based communication plan measured through baseline/follow-up retrospective chart audit and staff feedback. Methodology: Using Kotter’s change model, this QI project occurred at a 110-bed NH. A CMS quality measure (QM), ‘percent of residents whose need for help with activities of daily living has increased’ is derived from staff charting of NH residents’ activities of daily living (ADLs). Frequently missing, incomplete, and inaccurate ADL notes increase the risk of inaccurate QM data. Project activities (quality measure awareness at daily huddles, role play, and in-person discussions) occurred between September and November 2021. Outcomes were measured through retrospective chart audits across all shifts (N-night, D-day, E-evening), and staff feedback (baseline/follow-up) obtained using the Team Development Measure (TDM) tool. Results: Baseline chart audits (n=84) indicated 36 missing/60 incomplete /64 inaccurate ADL notes. Follow-up audits (n=84) showed 45 missing/59 incomplete/59 inaccurate ADL notes. Gaps persisted except incomplete and inaccurate evening shift notes which improved by 15.78% and 17.39%, respectively. No statistically significant relationships were identified between all ADL note categories - missing N/D/E notes (p= 1.000/p=0.400/p=0.371); incomplete N/D/E notes (p=0.646/p=0.581/p=0.223); and inaccurate N/D/E notes (p=0.703/p=0.285/p=1.000). Per TDM report, staff feedback from baseline (n=18) to follow-up (n=9) reflected a decline from stage 3 - building clarity of roles to stage 2 – building communication. Implications for Practice: Staff awareness of NH quality measures can promote safe resident-centered care, accurate data for quality measures, and reimbursement of NH care. Policies that address workplace barriers and staff accountability must be valued.

description: A GPS carrier-phase frequency transfer link along a baseline of 450 km has been established and is characterized by comparing it to a phase-stabilized optical fiber link of 920 km length, established between the two endpoints, the Max-Planck-Institut für Quantenoptik in Garching and the Physikalisch-Technische Bundesanstalt in Braunschweig. The characterization is accomplished by comparing two active hydrogen masers operated at both institutes. The masers serve as local oscillators and cancel out when the double differences are calculated, such that they do not constitute a limitation for the GPS link characterization. We achieve a frequency instability of 3 x 10^(-13) in 30 s and 5 x 10^(-16) for long averaging times. Frequency comparison results obtained via both links show no deviation larger than the statistical uncertainty of 6 x 10^(-16). These results can be interpreted as a successful cross-check of the measurement uncertainty of a truly remote end fiber link.

The Challenges and Opportunities of Implementing various Electronic-Payment Projects in Commercial Bank of Ethiopia: The case of Point of Sale (POS) Terminal.
Creators: name: Mesfin Betru
Publisher: name: Zenodo
Year: 2017

description: The main objective of this study is to identify the Challenges and Opportunities of Implementing various Electronic-Payment Projects in the Commercial Bank of Ethiopia: taking Point of Sale (POS) Terminal as a case study. Mixed research design was employed and primary data was collected through questionnaires and semi-structured interviews from employees and customers of the bank and analyzed using quantitative (statistical) and qualitative methods. The finding of this study reveals that the most challenging factor to the implementation of POS terminal is network failure. Organizational factors such as lack of employees' knowledge to answer customers' questions related to POS terminal, low support and follow up, lack of coordination and cooperation between different units of the bank viz. branches, districts, and E-payment process are considered as challenges in implementing POS terminal system. Moreover, payment mode factors such as double debit of accounts for single transaction due to connectivity failures, deduction of customers account for failed transactions are amongst the challenges identified by the study. Despite the aforementioned and other challenges, the study showed that Growing acceptance of POS terminal, the Business growth of the bank, NBE's policy direction that enforce banks to adopt technological innovation, change in the society life style i.e. the ongoing digital and technology revolution are some of the major opportunities identified by the study. Efforts at improving the connectivity of the network and security of transactions is recommended in order to efficiently adopt POS terminal payment system. Moreover, the study recommended the bank to raise public awareness on the use of payment cards for transactions on POS terminals, should improve the internal communication coordination, should facilitate proper and sustainable trainings for its employees to implement POS terminal payment system proficiently.

description: The recent BESIII announcement of a pseudoscalar glueball candidate makes an update on glueballs from lattice QCD timely. A brief review of how glueballs are studied in lattice QCD is given, and the reasons that glueballs are difficult to study both in lattice QCD with dynamical quarks and in experiments are outlined. Recent glueball studies in lattice QCD are then presented, and an exploratory investigation of the scalar glueball using glueball, meson, and meson-meson operators is summarized, suggesting that no scalar state below 2 GeV or so can be considered to be predominantly a glueball state.

Subjects: subject: Adaptation and Self-Organizing Systems (nlin.AO)
subject: FOS: Physical sciences

description: In many complex systems, states and interaction structure coevolve towards a dynamic equilibrium. For the adaptive contact process, we obtain approximate expressions for the degree distributions that characterize the interaction network in such active steady states. These distributions are shown to agree quantitatively with simulations except when rewiring is much faster than state update, and used to predict and to explain general properties of steady-state topologies. The method generalizes easily to other coevolutionary dynamics.

Care-Taking as Civilizing: Catholic Orphanages and the Mission Civilisatrice in Saint-Louis, Senegal, 1936-1949

description: For nearly a century, the Catholic Sœurs de Saint Joseph de Cluny operated the Ndar Toute orphanage for mixed-race (métis) and African girls in the city of Saint-Louis, Senegal. By the 1940s, Popular Front reforms, citizenship laws, and even changes in the social and political culture of Saint-Louis itself, sparked questions about the responsibility of Catholic missions and colonial authorities to care for orphaned girls. After tracing a history of orphans in Saint-Louis, this paper examines subsidy requests, inspection reports, and mission documents to reveal that colonial administrators and Catholic missions held shifting and sometimes conflictual understandings of which children needed care, what form that care took, and for what purpose orphaned children were raised. Through considering both rhetoric and actions concerning orphaned children, this paper argues that, despite an increasingly welfarist colonial discourse, the civilizing mission on lived on past its expiration date in the bodies of orphaned children.
The Significance of Research Methods with Reference to Language Education in Higher Education.

Subjects: Education

description: This research paper investigates the significance of research in language education in the higher education sector. For this purpose, the researcher conducted a case study with twenty 4th year students studying English at the University of Human Development (UHD), Iraqi Kurdistan Region. They were selected based on purposive sampling. The participants were invited to respond to a questionnaire that was created and piloted by the researcher. They were also requested to take part in a structured interview. The findings show that the nature of research methods for 4th year students across higher education is complex and elusive. The findings also show that most of the students almost have the same problems and they have similar views on their final project as they started at the beginning of the final year of the academic year (2018-2019) at the University of Human Development.

description: The methanol solvomorph 1 ⋅ 2MeOH of the cobalt(II) complex [Co(LSal,2−Ph)2] (1) with the sterically demanding Schiff-base ligand 2-(([1,1′-biphenyl]-2-ylimino)methyl)phenol (HLSal,2−Ph) shows the thus far largest dihedral twist distortion between the two chelate planes compared to an ideal pseudotetrahedral arrangement. The cobalt(II) ion in 1 ⋅ 2MeOH exhibits an easy-axis anisotropy leading to a spin-reversal barrier of 55.3 cm−1, which corresponds to an increase of about 17 % induced by the larger dihedral twist compared to the solvent-free complex 1. The magnetic relaxation for 1 ⋅ 2MeOH is significantly slower compared to 1. An in-depth frequency-domain Fourier-transform (FD-FT) THz-EPR study not only allowed the direct measurement of the magnetic transition between the two lowest Kramers doublets for the cobalt(II) complexes, but also revealed the presence of spin-phonon coupling. Interestingly, a similar dihedral twist correlation is also observed for a second pair of cobalt(II)-based solvomorphs, which could be benchmarked by FD-FT THz-EPR.
