Leptopelis viridis

description: Leptopelis viridis (Günther, 1869)
Green Tree Frog
Material: One male, NGK-Nimba 0083, and one female, NGK-Nimba 0086 (Fig. 6H).
Comments: Leptopelis viridis is a savannah frog, which is also encountered in herbaceous vegetation from the semi-decideous forest zone. It ranges across the northern part of sub-Saharan Africa (Schiøtz 1967; Rödel 2000; Channing and Rödel 2019). The species was recorded within grassland at the foot of Mounts Nimba (07°35.453’N, 008°24.957’W; 843 m asl). Additional populations were recorded in the Yéalé village, on shrubs, palm trees, and herbaceous plants (07°31.928’N, 008°25.401’W; 425 m asl). The males measured 32.0‒34.0 mm (N = 6), while a single recorded female reached 36.0 mm SUL.

Nimbaphrynoides occidentalis

description: Nimbaphrynoides occidentalis (Angel, 1943)
Nimba Toad
Material: No voucher.
Comments: Nimbaphrynoides occidentalis is a unique toad, being viviparous and endemic to a very limited range of a total of 4 km 2 on the ridges of the Mounts Nimba between Liberia, Guinea, and Ivory Coast (Lamotte 1959; Lamotte and Sanchez-Lamotte 1999; Hillers et al. 2008b; Sandberger-Loua et al. 2016, 2017). The toads live in montane grasslands above 1,200 m asl, where they go into dormancy during the dry season (Lamotte 1959; Hillers et al. 2008; Sandberger et al. 2010). Nimbaphrynoides occidentalis comprises two subspecies isolated by a forested mountain ridge: the larger N. occidentalis liberiensis is restricted to one site in Liberia, while N. occidentalis occidentali s occurs in a few sub-populations in Guinea and Ivory Coast (Sandberger et al. 2010). We found N. occidentalis occidentalis at 1,235 m asl, on very humid steep slopes in the montane grassland (07°35.555’N, 008°25.788’W; 1,235 m asl). Four juveniles and one female were discovered under rocks. The sizes of the juveniles ranged from 12.0‒14.0 mm while the female measured 23.0 mm. The basic dorsal color of the juveniles was dark brown, with a somewhat irregular mixture of light brown and white spots. Their snout, eyelids, and legs were colored light brown. The juveniles showed a pattern typical for adult males (Fig. 7A), whereas the female had a nearly uniform light brown dorsal color (Fig. 7B). The main threat for this species in Ivory Coast is bush fires in the dry season. A detailed assessment of the distribution and population sizes of N. occidentalis occidentalis from Ivory Coast is urgently needed.

description: We consider the problem of black-box multi-objective optimization (MOO) using expensive function evaluations (also referred to as experiments), where the goal is to approximate the true Pareto set of solutions by minimizing the total resource cost of experiments. For example, in hardware design optimization, we need to find the designs that trade-off performance, energy, and area overhead using expensive computational simulations. The key challenge is to select the sequence of experiments to uncover high-quality solutions using minimal resources. In this paper, we propose a general framework for solving MOO problems based on the principle of output space entropy (OSE) search: select the experiment that maximizes the information gained per unit resource cost about the true Pareto front. We appropriately instantiate the principle of OSE search to derive efficient algorithms for the following four MOO problem settings: 1) The most basic em single-fidelity setting, where experiments are expensive and accurate; 2) Handling em black-box constraints} which cannot be evaluated without performing experiments; 3) The discrete multi-fidelity setting, where experiments can vary in the amount of resources consumed and their evaluation accuracy; and 4) The em continuous-fidelity setting, where continuous function approximations result in a huge space of experiments. Experiments on diverse synthetic and real-world benchmarks show that our OSE search based algorithms improve over state-of-the-art methods in terms of both computational-efficiency and accuracy of MOO solutions.

Ancient Peruvian sprang fabrics
Creators: name: Frame, Mary Patricia
Publisher: name: University of British Columbia
Year: 2010

description: This paper attempts to develop a technical feature of ancient Peruvian fabrics as a dating tool by describing its occurrence as fully as possible. The fabrics in this study share a common technique or method of manufacture which has been called "sprang". Sprang is a weftless technique of interworking a set of parallel elements fixed at both ends and it is characterized by the duplication of fabric in mirror-image symmetry at both ends of the warp. Structural peculiarities which remain in the finished fabric allow the identification of the method of manufacture. A large sample of sprang fabrics was identified, analyzed, replicated and diagrammed. They were grouped on the basis of structural similarity. The fabrics were dated through grave association, where possible, "but primarily through comparative stylistic and iconographic analysis. The andent Peruvian sprang fabrics are presented chronologically by horizon and period. Within each time segment, the sample is grouped by structure. What results is a profile of the sprang technique - the variations in structures, the modifications to the basic technique and the differing functions of the finished fabrics - as it is used through time. By cross-checking technical groupings with grave association, style and iconography, it emerges that certain technical features are diagnostic of the originating culture. The application of this information includes the identification of undocumented fabrics in museum collections and the expansion of the iconographic repertory of some styles. The evolution of the techniques of sprang in ancient Peru is broadly sketched and some internal sequencing of the larger groups of technically associated sprang fabrics is proposed. The iconographic study of the sprang fabrics leads to some insights into the importance of fabric making within ancient Peruvian culture. In particular, the repeated association of the serpent with images of fabric structures in the sprang sample of the Early Horizon illuminates the significance of fabric and fabric making.

On the Power of Quantum Encryption Keys

description: The standard definition of quantum state randomization, which is the quantum analog of the classical one-time pad, consists in applying some transformation to the quantum message conditioned on a classical secret key $k$. We investigate encryption schemes in which this transformation is conditioned on a quantum encryption key state $ρ_k$ instead of a classical string, and extend this symmetric-key scheme to an asymmetric-key model in which copies of the same encryption key $ρ_k$ may be held by several different people, but maintaining information-theoretical security. We find bounds on the message size and the number of copies of the encryption key which can be safely created in these two models in terms of the entropy of the decryption key, and show that the optimal bound can be asymptotically reached by a scheme using classical encryption keys. This means that the use of quantum states as encryption keys does not allow more of these to be created and shared, nor encrypt larger messages, than if these keys are purely classical.

Northern Flat-backed Toad
Material: Two males, NGK-Nimba 0043, NGK-Nimba 0051 (Fig. 7C), and one female, NGK-Nimba 0058 (Fig. 7D).
Comments: Sclerophrys maculata is a common toad with flat and granular parotid glands living in the savannah zone and edges of heavily degraded forests (Rödel 2000; Poynton et al. 2016). Toads were found in grassy pastures at the foot of Mounts Nimba (07°35.258’N, 008°25.052’W; 821 m asl), and some females were also observed occasionally together with S. togoensis on forest trails (07°32.993’N, 008°24.753’W; 425 m asl). Further records were obtained in the Yéalé village (07°31.928’N, 008°25.401’W; 425 m asl), mostly along dirt roads in puddles, around houses, or in plantations at swamp edges. The body sizes of two males were 46.0 and 49.0 mm, while females measured 41.5– 69.0 mm (N = 5). During the reproductive period, some males exhibited a remarkable yellow color.

description: In this work, analyzing the propagation of electromagnetic waves in the field of gravitational waves, we show the presence and significance of the so called surfing effect for pulsar timing measurements. It is shown that, due to the transverse nature of gravitational waves, the surfing effect leads to enormous pulsar timing residuals if the speed of gravitational waves is smaller than speed of light. This fact allows to place significant constraints on parameter $ε$, which characterizes the relative deviation of the speed of gravitational waves from the speed of light. We show that the existing constraints from pulsar timing measurements already place stringent limits on $ε$ and consequently on the mass of graviton $m_g$. These limits on $m_g$ are three orders of magnitude stronger than the current constraints from Solar System tests. The current constraints also allow to rule out massive gravitons as possible candidates for cold dark matter in galactic halo. In the near future, the gravitational wave background from extragalactic super massive black hole binaries, along with the expected sub-microsecond pulsar timing accuracy, will allow to achieve constrains of $ε\lesssim 0.4\%$ and possibly stronger.

description: The Internet has provided a door to communications with the world. Opportunities to communicate with people of common interests in remote and geographically distant areas provide a variety of comment, different experiences and learning potential for everyone connected to the system. This paper reviews my Internet learning process as a non-computer specialist; several different approaches to earning money through this medium; and where farm managers are able to benefit in the future. For people on the information supply side of the Internet, five major means for making money are discussed:
(1) contracting with business and government to provide specific information;
(2) providing an advertising service;
(3) providing courses and newsletters at a fee;
(4) collecting a finder's fee for linking potential customers with manufacturers; and
(5) providing information on specific topics for a fee.
On the demand side, farm managers benefit from the wide variety of information available on the Interent, electronic mail for fast communication, newsgroups on . specific topic areas and mailing lists, all at reasonable cost.

description: The Cahn-Hilliard equation describes phase separation in binary liquids. Here we study this equation with spatially-varying sources and stirring, or advection. We specialize to symmetric mixtures and time-independent sources and discuss stirring strategies that homogenize the binary fluid. By measuring fluctuations of the composition away from its mean value, we quantify the amount of homogenization achievable. We find upper and lower bounds on our measure of homogenization using only the Cahn-Hilliard equation and the incompressibility of the advecting flow. We compare these theoretical bounds with numerical simulations for two model flows: the constant flow, and the random-phase sine flow. Using the sine flow as an example, we show how our bounds on composition fluctuations provide a measure of the effectiveness of a given stirring protocol in homogenizing a phase-separating binary fluid.

The effect of immobilization on ligamentous healing and strength of the medial collateral ligament of the rat knee
Creators: name: Pisesky, Wayne Anthony
Publisher: name: University of British Columbia
Year: 2010

description: The purpose of this study was to determine the effects of varying periods of immobilization on ligamentous healing and strength in a rat experimental model. Sixty-one mature male Wistar rats were used. The left knee medial collateral ligament was surgically exposed, divided, and repaired. The rats were randomly placed into one of four groups: Group A, no immobilization, Group B, 2 weeks' immobilization, Group C, 6 weeks' immobilization, and Group D, 10 weeks' immobilization of the operated limb. The right knee served as a control. The ligaments were studied histologically and biomechanically at 2 weeks, 6 weeks, 10 weeks and 20 weeks post-operatively. Histologic samples were objectively evaluated with the light microscope using a Maturity Index Score and Scale that were devised based on the numbers and orientation of the fibroblasts and the amount and orientation of the collagen fibres. Ligament-bone preparations were studied using an Instron material testing machine to determine the biomechanical properties of the ligament until failure. Utilizing the Maturity Index Score and Scale, it was shown that Group A, with no immobilization, matured more rapidly than the other groups, and achieved full maturity at 20 weeks post-operatively. The other groups all showed a retarded rate of healing while immobilized. The electron microscopic study supported this data by demonstrating the level of metabolic activity of the fibroblasts which decreased with increasing maturity and by demonstrating that the size, amount and orientation of the collagen fibers increased with mobilization. The biomechanical testing showed that at 2 weeks post-operative, Group A had achieved a strength which was 46% of controls while Group B was only 29% of controls (p = 0.055). At 6 weeks Group A was 65% of controls, Group B was 56% of controls and Group C was 39% of controls (p = 0.0004). At 20 weeks Group A was 83% of controls, Group B was 71% of controls, Group C was 66% of controls and Group D was 48% of controls (p = 0.0005). Group A was 71% stronger than Group D at this time, indicating that the healing medial collateral ligament attained a greater strength and histologically matured more rapidly if mobilization is begun immediately.

description: The development of flexible and reconfigurable sensors that can be readily tailored toward different molecular analytes constitutes a key goal and formidable challenge in biosensing. In this regard, synthetic nanopores have emerged as potent physical transducers to convert molecular interactions into electrical signals. Yet, systematic strategies to functionalize their surfaces with receptor proteins for the selective detection of molecular analytes remain scarce. Addressing these limitations, a general strategy is presented to immobilize nanobodies in a directional fashion onto the surface of track‐etched nanopores exploiting copper‐free click reactions and site‐specific protein conjugation systems. The functional immobilization of three different nanobodies is demonstrated in ligand binding experiments with green fluorescent protein, mCherry, and α‐amylase (α‐Amy) serving as molecular analytes. Ligand binding is resolved using a combination of optical and electrical recordings displaying quantitative dose–response curves. Furthermore, a change in surface charge density is identified as the predominant molecular factor that underlies quantitative dose–responses for the three different protein analytes in nanoconfined geometries. The devised strategy should pave the way for the systematic functionalization of nanopore surfaces with biological receptors and their ability to detect a variety of analytes for diagnostic purposes.

description: Traditionally, the farm gate has been perceived as a substantial barrier behind which farmers could exercise almost unfettered managerial independence and through which the farmers managerial skills did not have to extend. Globalization and the industrialization of some agricultural industries has meant that farms must be much more integrated with the wider economy than in the past. The increased movement to production of tailored rather than generic commodities has meant that others in the supply chain have a greater interest in on-farm managerial practices - meaning that they now pass through the farm gate. Increased information and the expansion of contracts at the expense of spot markets means that farmers must move beyond the farm gate to acquire information on desired product quality, prices and to engage in one-on-one contract negotiations. These trends are explored and the demands they make on the managerial skills of farmers are discussed.

description: This paper is devoted to the use of hybrid Petri nets (PNs) for modeling and control of hybrid dynamic systems (HDS). Modeling, analysis and control of HDS attract ever more of researchers' attention and several works have been devoted to these topics. We consider in this paper the extensions of the PN formalism (initially conceived for modeling and analysis of discrete event systems) in the direction of hybrid modeling. We present, first, the continuous PN models. These models are obtained from discrete PNs by the fluidification of the markings. They constitute the first steps in the extension of PNs toward hybrid modeling. Then, we present two hybrid PN models, which differ in the class of HDS they can deal with. The first one is used for deterministic HDS modeling, whereas the second one can deal with HDS with nondeterministic behavior.

description: We obtain the distribution amplitude (DA) of the pion from its light-front wave functions in the basis light-front quantization framework. This light-front wave function of the pion is given by the lowest eigenvector of a light-front effective Hamiltonian consisting a three-dimensional confinement potential and the color-singlet Nambu--Jona-Lasinion interaction both between the constituent quark and antiquark. The quantum chromodynamics (QCD) evolution of the DA is subsequently given by the perturbative Efremov-Radyushkin-Brodsky-Lepage evolution equation. Based on this DA, we then evaluate the singly and doubly virtual transition form factors in the space-like region for $π^0\rightarrow γ^*γ$ and $π^0\rightarrow γ^*γ^*$ processes using the hard-scattering formalism. Our prediction for the pion-photon transition form factor agrees well with data reported by the Belle Collaboration. However, in the large $Q^2$ region it deviates from the rapid growth reported by the BaBar Collaboration. Meanwhile, our result on the $π^0\rightarrow γ^*γ^*$ transition form factor is also consistent with other theoretical approaches and agrees with the scaling behavior predicted by perturbative QCD.

description: We study the growing time scales and length scales associated with dynamical slow down for a realistic glass former, using computer simulations. We perform finite size scaling to evaluate a length scale associated with dynamical heterogeneity which grows as temperature decreases. However, relaxation times which also grow with decreasing temperature, do not show the same kind of scaling behavior with system size as the dynamical heterogeneity, indicating that relaxation times are not solely determined by the length scale of dynamical heterogeneity. We show that relaxation times are instead determined, for all studied system sizes and temperatures, by configurational entropy, in accordance with the Adam-Gibbs relation, but in disagreement with theoretical expectations based on spin-glass models that configurational entropy is not relevant at temperatures substantially above the critical temperature of mode coupling theory. The temperature dependence of the heterogeneity length scale shows significant deviations from theoretical expectations, and the length scale one may extract from the system size dependence of the configurational entropy has much weaker temperature dependence compared to the heterogeneity length scale at all studied temperatures. Our results provide new insights into the dynamics of glass-forming liquids and pose serious challenges to existing theoretical descriptions.

Togo Toad
Material: Three males, NGK-Nimba 0004, NGK-Nimba 0028, NGK-Nimba 0029 (Fig. 7G), and one female, NGK-Nimba 0050 (Fig. 7H).
Comments: This toad has a patchy distribution in primary forests from Togo to Sierra Leone, and mainly breeds in shallow forest streams during the dry season (Rödel and Bangoura 2004; Rödel et al. 2004). Four specimens were found in different forest patches. The variable color pattern of this species has been deescribed by Rödel and Bangoura (2004), Channing and Rödel (2019), and Gongomin et al. (2019). Diagnostic is the parallel, straight, narrow, and angular parotid glands, running parallel to the side of the body. Two males were encountered in a patch of dense forest crossed by a shallow stream (07°33.440’N, 008°24.657’W; 439 m asl). A female was found together with another male among humid litter on a forest trail (07°32.993’N, 008°24.753’W; 425 m asl). While the female measured 64.0 mm, the SULs of the three males ranged from 40.5–44.5 mm. In Ivory Coast, S. togoensis is highly threatened by deforestation (Gongomin et al. 2019).

description: Hungarian agriculture has been under a radical social-economic transition,which results in fundamental changes in the ownership, production and organization structure of the sector. Both countries Italy and Hungary as well have been actively involved in a reform process of agricultural policy from, different positions and reasons. The process of reform of CAP will be pursued further necessitates new adjustments of Italy as a member of EU. The key-elements of the success of this process are the development of human resource, as well as improved information supply for agricultural decision makers, which should be based upon the wide and more effective use of advanced information technology (IT). This is one of the key challenges for the reform of education, research and extension services. Both sub-regions Perugia in Italy and Szarvas-Koros in Hungary with considerable historical roots and well-functioning institutions of agricultural and environmental education and research, will have a fundamental role in this process amongst other rural higher educationcenters. Recent changes in rural economy, society and environment necessitate system-oriented research using IT tools In scope of this project the exchange of ideas, knowledge and methodologies, about advanced application of IT could provide adaptable ideas and examples for other sub-regions in both sides.

description: We consider the generalized Tolman solution of general relativity, describing the evolution of a spherical dust cloud in the presence of an external electric or magnetic field. The solution contains three arbitrary functions $f(R)$, $F(R)$ and $τ_0(R)$, where $R$ is a radial coordinate in the comoving reference frame. The solution splits into three branches corresponding to hyperbolic ($f >0$), parabolic ($f=0$) and elliptic ($f < 0$) types of motion. In such models, we study the possible existence of wormhole throats defined as spheres of minimum radius at a fixed time instant, and prove the existence of throats in the elliptic branch under certain conditions imposed on the arbitrary functions. It is further shown that the normal to a throat is a timelike vector (except for the instant of maximum expansion, when this vector is null), hence a throat is in general located in a T-region of space-time. Thus if such a dust cloud is placed between two empty (Reissner-Nordström or Schwarzschild) space-time regions, the whole configuration is a black hole rather than a wormhole. However, dust clouds with throats can be inscribed into closed isotropic cosmological models filled with dust to form wormholes which exist for a finite period of time and experience expansion and contraction together with the corresponding cosmology. Explicit examples and numerical estimates are presented. The possible traversability of wormhole-like evolving dust layers is established by a numerical study of radial null geodesics.

description: We report new precision measurements of the properties of our Galaxy's supermassive black hole. Based on astrometric (1995-2007) and radial velocity (2000-2007) measurements from the W. M. Keck 10-meter telescopes, a fully unconstrained Keplerian orbit for the short period star S0-2 provides values for Ro of 8.0+-0.6 kpc, M_bh of 4.1+-0.6x10^6 Mo, and the black hole's radial velocity, which is consistent with zero with 30 km/s uncertainty. If the black hole is assumed to be at rest with respect to the Galaxy, we can further constrain the fit and obtain Ro = 8.4+-0.4 kpc and M_bh = 4.5+-0.4x10^6 Mo. More complex models constrain the extended dark mass distribution to be less than 3-4x10^5 Mo within 0.01 pc, ~100x higher than predictions from stellar and stellar remnant models. For all models, we identify transient astrometric shifts from source confusion and the assumptions regarding the black hole's radial motion as previously unrecognized limitations on orbital accuracy and the usefulness of fainter stars. Future astrometric and RV observations will remedy these effects. Our estimates of Ro and the Galaxy's local rotation speed, which it is derived from combining Ro with the apparent proper motion of Sgr A*, (theta0 = 229+-18 km/s), are compatible with measurements made using other methods. The increased black hole mass found in this study, compared to that determined using projected mass estimators, implies a longer period for the innermost stable orbit, longer resonant relaxation timescales for stars in the vicinity of the black hole and a better agreement with the M_bh-sigma relation.

description: The variations in volume and quality of the milk due to the current system of production in Norwegian goat dairy farming complicate production of brand goat cheeses. In the specialised goat dairy farming system most kids are also culled right after birth and there are currently few options for utilising the meat. In this paper the farm economics of an alternative system with altered period of kidding, currently in the periodfrom January to March, combined with production of meat and cashmere fibre is examined. May kidding combined with raising the kids for 8 months yielded the most promising economical return, however depending upon the fibre output and expected decrease in milk yield. Compared to the present system the changes would be favourable from an animal welfare point of view.
