A Study of the Hibernation of Bumblebees (Hymenoptera:Bombidae) in Southern England

In temperate parts of the world such as the British Isles, bumblebee colonies are annual, since only the young queens are able to survive the winter, while the old queens, workers and males all die. The young, fertilized queens produced during the summer months enter hibernation, and it is these bumblebees which reappear in the following spring and later form colonies of their own. In southern England the period of hibernation may last anything from 6 to 9 months, depending on the species and to some extent on spring temperatures. Hibernation is, therefore, an important yet neglected aspect of bumblebee biology. Previous workers (Sladen 1912; Bols 1937, 1939) have indicated that well-drained banks or slopes with a north or north-west exposure are favourite sites for hibernating bumblebees, and both Wagner (1907) and Sladen (1912) have stated that bumblebees hibernate under trees, but do not give precise details. Bumblebees have also been recorded hibernating in rotten tree stumps (Frison 1926; Tkalcu 1960, 1961), under moss, leaves and piles or rubbish (Verrill, in Putnam 1864; Sladen 1912; and others), and in various other miscellaneous places. Plath (1927, 1934), Frison (1929) and Townsend (1951) have all reported the occurrence of many queens of the New World species Bombus impatiens (Cresson) hibernating in very close proximity to one another, and presumably in all these cases the queens were hibernating about the entrance to their maternal nest. However, much of the information on the hibernation of bumblebees so far published has accumulated from casual observations which have not been followed up by more critical data, and apparently only Sladen has investigated the subject of the natural hibernation of bumblebees in this country. In the present studies an attempt has been made to obtain data on various aspects of the natural hibernation of bumblebees and where possible differences between species or groups of species have been investigated.
USE OF ANTI-EPILEPTIC DRUGS (AED’s) IN PREGNANT WOMEN, THEIR RISK AND SAFETY MEASURES: A META-ANALYSIS

Aim and Objective: To assess the risks and safety measures in use of antiepileptic drugs in pregnant women. Methods: Data on AED use and maternal characteristics were collected through metaanalysis, in which malformations were confirmed by medical records . The risk of major malformations was calculated among infants of mothers exposed to specific AEDs in monotherapy or polytherapy during the 1st trimester of pregnancy and among an unexposed groups. Results: The full outcome data were collected by meta-analysis. There were fewer MCMs for pregnancies exposed only to Lamotrigine than only to Valproate . Polytherapy combinations containing valproate carried a higher risk MCM than combinations not containing valproate. Safety Measures: Use of Second generation AEDs to prevent risks, monotherapy of AEDs and Therapeutic Drug Monitoring by setting Individual AED target concentrations in pregnant women are considered to be beneficial. Conclusion: We conclude that second generation AEDs should be adjusted back to preconception doses are slightly higher over 2 weeks –3 months, depending on the AED.
Genetic diversity of eight millet genera assessed by using molecular and morphological markers

Abstract. In this study, the genetic diversity and relationships among eight millet genera were investigated by molecular and morphological data analyses. Sixty-nine millet accessions were analysed by using amplified fragment length polymorphism (AFLP) markers, and evaluated for morphological traits. Eight AFLP primer pairs were amplified successfully and 779 bands were scored for all accessions, with a high level of polymorphism detected. Nei’s genetic distance among all accessions varied from 0.0123 to 0.4246 and the Shannon’s index was estimated at 0.9708. The neighbour joining tree, using the unweighted neighbour-joining method and Dice’s dissimilarity coefficient, was constructed. The AFLP markers revealed the close relatedness between the Eragrostis and Panicum genera, whereas the greatest distance was found the Pennisetum and Echinochloa genera. Cluster analysis based on the AFLP profiles revealed that the majority of accessions of a given millet genus tend to group together. Clustering from morphological data allocated individuals into three main clusters with high variation. The genetic variability found between the analysed accessions was weakly negatively correlated (r = –0.074) with their morphological attributes. However, high molecular and morphological variability indicated that this collection includes rich and valuable plant materials for millet breeding.
Multiscale Segmentation of Microscopic Images

The chapter introduces multiscale methods for image analysis and their applications to segmentation of microscopic images. Specifically, it presents mathematical morphology and linear scale-space theories as overarching signal processing frameworks without excessive mathematical formalization. The chapter introduces several differential invariants, which are computed from parametrized Gaussian kernels and their derivatives. The main application of this approach is to build a multidimensional multiscale feature space, which can be subsequently used to learn characteristic fingerprints of the objects of interests. More specialized applications, such as anisotropic diffusion and detection of blob-like and fiber-like structures, are introduced for two-dimensional images, and extensions to three-dimensional images are discussed. Presented approaches are generic and thus have broad applicability to time-varying signals and to twoand three-dimensional signals, such as microscopic images. The chapter is intended for biologists and computer scientists with a keen interest in the theoretical background of the employed techniques and is in part conceived as a tutorial.
Chromosomal Homologies and Evolution of Testudinoid Turtles with Emphasis on the Systematic Placement of Platysternon

The karyotype of Platysternon (2n = 54) is compared to members of the Chelydridae, Emydidae and Kinosternidae and is found to be the most similar to the primitive batagurine emydid condition (2n = 52). The batagurine karyotype can be derived from that of Platysternon (or the reverse) by one event whereas several are required to derive Platysternon from either Chelydra or Macroclemys. Moreover, derived chromosomal characters are shared between Platysternon and emydids. It is proposed that the Platysternidae (Gray) may be valid, including only Platysternon. Chromosomal data are also used to develop a phylogeny of the Testudinoidea in which the Chelydridae is found to be an early offshoot of the emydid-testudinid line and the Platysternidae is derived from a later form ancestral to the Emydidae and Testudinidae.
HMDPose: A large-scale trinocular IR Augmented Reality Glasses Pose Dataset

Augmented Reality Glasses usually implement an Inside-Out tracking. In case of a driving scenario or glasses with less computation capabilities, an Outside-In tracking approach is required. However, to the best of our knowledge, no public datasets exist that collects images of users wearing AR glasses. To address this problem, we present HMDPose, an infrared trinocular dataset of four different AR Head-mounted displays captured in a car. It contains sequences of 14 subjects captured by three different cameras running at 60 FPS each, adding up to more than 3,000,000 labeled images in total. We provide a ground truth 6DoF-pose, captured by a submillimeter accurate marker-based tracker. We make HMDPose publicly available for non-profit, academic use and non-commercial benchmarking on ags.cs. uni-kl.de/datasets/hmdpose/.
Fabrication and stability of GO/Al2O3 composite nanofiltration membranes

Using an tubular Al2O3 ultrafiltration membrane with an average pore diameter of 20 nm as the carrier, after modified by dopamine, a pressure-driven deposition method was used to successfully prepare a GO/Al2O3 composite nanofiltration membrane that can be stable in aqueous solution for a long time. The thickness of GO layer can be controlled by changing the loading amount. The results showed that the pure water permeability of all GO/ Al2O3 composite nanofiltration membranes decreased and then reached a steady state during the cross-flow filtration. In addition, the pure water permeability of GO/Al2O3 composite nanofiltration membranes decreased as the GO loading amount increased. The permeability and rejection of GO/Al2O3 composite nanofiltration membranes remained stable when GO loading amount was greater than 90 mg/m2. As the storage time (in pure water) extended, the cross-linking of GO sheets caused by residual salt ions during tests led to a higher rejection of GO/Al2O3 composite nanofiltration membranes towards monovalent and divalent salts. After being immersed in pure water for 680 h, the GO/Al2O3 composite nanofiltration membrane with GO loading amount of 140 mg/m2 showed the highest 研究论文 DOI:10.11949/0438-1157.20200205 收稿日期:2020-02-28 修回日期:2020-04-07 通信作者:漆虹(1974—),男,博士,研究员,hqi@njtech.edu. cn 第一作者:汪菊(1995—),女,硕士研究生,2543303804@qq.com 基金项目:国家自然科学基金项目(21490581);中国石油化工股份有限公司资助项目(317008-6) 引用本文:汪菊,牛淑锋,费莹,漆虹 .

Isotopic Data for Inferring Groundwater Dynamics in Cagayan de Oro City, Philippines

A groundwater study was conducted in Cagayan de Oro City (CDO) located in the north-central part of Mindanao, the Philippines using isotopic techniques. The study identifies the recharge sources of the groundwater in the city and estimates the groundwater age and groundwater recharge rate. Monthly integrated samplings of rainfall were conducted in three locations of varying altitudes from October 2012 to March 2015. Groundwater samples from production wells and shallow wells were also collected within the same period at least twice, during the dry and the wet seasons. The samples were analyzed for their stable isotopic compositions and groundwater in selected deep wells was dated using tritium-helium dating. A meteoric water line of δD = (8.26 ± 0.21) δ18O + (11.56 ± 1.88) was calculated using the precipitation-weighted reduced major axis (PWRMA) method. Isotopic compositions of groundwater show that local precipitation recharges the shallow aquifer. An interaction exists between the shallow and deep aquifer possibly due to the absence of a well-defined multilayer aquifer based on available lithological profiles. Coastal shallow wells appear to be recharged from 35–80 meters above sea level (masl), while deep wells appear to be recharged from 200–300 masl. A recharge rate of 380 mm/yr was estimated, which is more than 20% of the average annual rainfall and twice the estimated recharge using the precipitation-based method.
Proposal for an experiment to measure the Hausdorff dimensionof quantum-mechanical trajectories

We make a proposal for a Gedanken experiment, based on the Aharonov-Bohm effect, how to measure in principle the zig-zagness of the trajectory of propagation (abberation from its classical trajectory) of a massive particle in quantum mechanics. Experiment I is conceived to show that contributions from quantum paths abberating from the classical trajectory are directly observable. Experiment II is conceived to measure average length, scaling behavior and critical exponent (Hausdorff dimension) of quantum mechanical paths.

Cyclin B1 expression in meiotically competent and incompetent goat oocytes

To start determining the nature of meiotic incompetence in goat oocytes, we have examined the expression of one of the potential pre‐MPF subunits: the cyclin B1. We have been isolating a small DNA probe encoding the goat cyclin B1 box to analyze the expression of the cyclin B1 gene in competent and incompetent goat oocytes. This probe was easily obtained by polymerase‐chain‐reaction (PCR) on reverse‐transcribed mRNA from granulosa cells, using cyclin B specific primers derived from a bovine cDNA. The transcript corresponding to cyclin B1 in goat granulosa cells is 1.8 kb. In situ hybridization analysis indicated that competent and incompetent oocytes contained cyclin B1 mRNA, but also that active cyclin B1 mRNA synthesis occured at the end of the growth phase, e.g., when oocytes progressed in the acquisition of meoitic competence. Western blot analysis, performed with a monoclonal anticyclin B1 antibody, revealed in competent and incompetent oocytes a polypeptide of 65kDa corresponding to the goat cyclin B1 protein. This pattern of cyclin B1 expression further suggested that meiotic incompetence in goat oocytes could not be primarily correlated with a lack of cyclin B1 protein as potential pre‐MPF subunit, but to a limiting amount of this protein.

Agents’ behavior and its conceptual framework

This note concentrates on the notion of agents’ behavior, as understood today, and suggests expanding it to study future socio-technical systems. The proposal is to take an ontological viewpoint to discuss anew topics like: how to understand behavior, how to connect behavior to an agents’ type, how to structure a broader framework for behavior studies. Due to space limitations, the presentation focuses on motivations and gives only a few guiding ideas. Overall, the aim is to foster the transformation of today’s socio-technical systems in inclusive systems where humans and artificial agents cohabit and, possibly, develop social practices, norms and other forms of collaboration [1].
Coat Color in Wild Populations of the Roof Rat in Hawaii

Rattus rattus rattus has occupied the Hawaiian Islands not longer than 188 years. Three coat color mutants are present and were probably introduced with the original colonizing stocks. Four principal populations are discerned from mapping of phenotype frequencies. It is postulated that coat colors by themselves are of neutral selective value, and that their present distributional pattern has arisen through pleiotropic action of the coat color genes whose major adaptive significance in local environments is physiological.
Seismic response analysis of RC frame core-tube building with self-centering braces

This paper examines the seismic responses of a reinforced concrete (RC) frame core-tube building with pre-pressed spring self-centering energy dissipation (PS-SCED) braces. The PS-SCED brace system consists of friction devices for energy dissipation, pre-pressed combination disc springs for self-centering and tube members as guiding elements. A constitutive model of self-centering flag-shaped hysteresis for PS-SCED brace is developed to better simulate the seismic responses of the RC frame core-tube building with PS-SCED braces, which is also verified by the tests of two braces under low cyclic reversed loading. Results indicate that the self-centering and energy dissipation capabilities are well predicted by the proposed constitutive model of the PS-SCED brace. The structure with PS-SCED braces presents similar peak story drift ratio, smaller peak acceleration, smaller base shear force and much smaller residual deformations as compared to the RC frame core-tube building with bucking-restrained braces (BRBs).
An instrumental variable based compressed sampling matching pursuit method for closed-loop identification

Abstract: For the identification of a class of closed-loop systems with unknown time-delays in both the control plant and the feedback controller, an instrumental variable based compressed sampling matching pursuit method is developed. By using the instrumental variable identification idea to modify the compressed sampling matching pursuit algorithm, the sparse parameter vector of the overparameterized identification model is firstly estimated. Then the estimates of the control plant parameters and the time-delays can be extracted from the estimated parameter vector, and the parameters of the feedback controller can be obtained by using the model equivalence principle. Simulation results show that the proposed method can effectively estimate the parameters and time-delays for the class of closed-loop systems with only a few iterations.
Multiple Fault Isolation in Redundant Systems

We consider the problem of sequencing tests to isolate multiple faults in redundant (fault-tolerant) systems with minimum expected testing cost (time). It can be shown that single faults and minimal faults, i.e., minimum number of failures with a failure signature different from the union of failure signatures of individual failures, together with their failure signatures, constitute the necessary information for fault diagnosis in redundant systems. In this paper, we develop an algorithm to find all the minimal faults and their failure signatures. Then, we extend the Sure diagnostic strategies [1] of our previous work to diagnose multiple faults in redundant systems. The proposed algorithms and strategies are illustrated using several examples.
Changing forms of employment : organisations, skills and gender

During the last two decades there has been widespread evidence of change in specific aspects of employing organizations, employment and employment related institutions. Changing Forms of Employment looks at the underlying trends which generate pressures towards a fundamental reshaping of social institutions in three ways: changes in the organization of production, particularly those associated with the growth of service dominated economics; the effects of technological change, particularly those associated with Information Technology; the erosion of the 'male breadwinner' (or single earner) model of employment and household. These trends have resulted in strains and ruptures in the organization and regulation of employment, and related institutions including trade unions, employers, and households. The task of the next decade is to both reconstruct relationships, and to renew institutions.

A re-appraisal of palaeoenvironmental history in Central Africa: evidence for a major fluvial refuge in the Zaire Basin

Pleistocene refuge theory has been strengthened in the Neotropics by much prominent and recent work. In contrast, models developed in the 1960s for Central African tropics are still retained to-day. Because these were based on knowledge of highland palaeoenvironments and bioge- ography, and on an almost blank page for lowland forests of the Central Zaire Basin, the discrimination between lowland and montane faunas remained imprecise, and their relative histories somewhat confused. Results of a 5-year study on primate distribution and systematics in the Zaire Basin do not support the previously proposed diversity gra- dients, and show that the so-called East Central major

Gravitational Lensing by Clusters of Galaxies

Gravitational lensing by clusters of galaxies affects the cosmic X-ray background (XRB) by altering the observed density and flux distribution of background X-ray sources. At faint detection flux thresholds, the resolved X-ray sources appear brighter and diluted, while the unresolved component of the XRB appears dimmer and more anisotropic, because of lensing. The diffuse X-ray intensity in the outer halos of clusters might be lower than the sky-averaged XRB, after the subtraction of resolved sources. Detection of the lensing signal with a wide-field X-ray telescope could probe the mass distribution of a cluster out to its virialization boundary. In particular, we show that the lensing signature imprinted on the resolved component of the XRB by the cluster A1689 should be difficult, but possible, to detect out to 8' at the 2-4 σ level, after 106 s of observation with the forthcoming Advanced X-Ray Astrophysics Facility (AXAF) satellite. The lensing signal is fairly insensitive to the lens redshift in the range 0.1 ≲ zl ≲ 0.6. The amplitude of the lensing signal is, however, sensitive to the faint-end slope of the number-flux relation for unresolved X-ray sources, and it can thus help constrain models of the XRB. A search for X-ray arcs or arclets could identify the fraction of all faint sources that originate from extended emission of distant galaxies. The probability for a 3 σ detection of an arclet that is stretched by a factor of approximately 3 after a 106 s observation of A1689 with AXAF is roughly comparable to the fraction of all background X-ray sources that have an intrinsic size of approximately 1''.
Iron Metabolism in BeWo Chorion Carcinoma Cells

Growing human choriocarcinoma BeWo b24 cells contain 1.5 X 10‘ functional cell surface transferrin binding sites and 2.0 X 10’ intracellular binding sites. These cells rapidly accumulate iron at a rate of 360,000 iron atoms/min/cell. During iron uptake the transferrin and its receptor recycle at least each 19 min. The accumulated iron is released from the BeWo cells at a considerable rate. The time required to release 50% of previously accumulated iron into the extracellular medium is 30 h. This release process is cell line-specific as HeLa cells release very little if any iron. The release of iron by BeWo cells is stimulated by exogenous chelators such as apotransferrin, diethylenetriaminepenta-acetic acid, desferral, and apolactoferrin. The time required to release 50% of the previously accumulated iron into medium supplemented with chelator is 15 h. In the absence of added chelators iron is released as a low molecular weight complex, whereas in the presence of chelator the iron is found complexed to the chelator. Uptake of iron is inhibited by 250 PM primaquine or 2.5 PM monensin. However, the release of iron is not inhibited by these drugs. Intracellular iron is stored bound to ferritin. A model for the release of iron by BeWo cells and its implication for transplacental iron transport is discussed.
