description: It is demonstrated theoretically that the counter-rotating quadrupole mode in a vortex of Bose-Einstein condensates can decay into a pair of Kelvin modes via Beliaev process. We calculate the spectral weight of density-response function within Bogoliubov framework, taking account of both Beliaev and Landau processes. Good agreement with experiment on $^{87}$Rb by Bretin et al. [cond-mat/0211101] allows us to unambigiously identify the decayed mode as the Kelvin wave propagating along a vortex line.

description: The present study has been conducted to know the general profile, educational status, activities performed and income of the migratory child labour vis-a-vis the natives engaged in agricultural activities in Punjab. The study is based on a sample of twelve villages randomly taken from three agro-climatic zones. In all the villages, 302 children working in agricultural sector were identified and all of them were the respondents of this study. It has been found that about one-fourth of the child labour working in agricultural and allied activities in the state of Punjab are migrants from other states, viz. Uttar Pradesh, Bihar, Uttarakhand and Himachal Pradesh. Most of the migrant child workers were in the age group of 12-14 years. The ratio of female child labour was higher in migrants than in natives. A very high number of child labour belonging to both migrant and native families were from scheduled caste families. All the migratory working children belonged to the landless families of labourers. The educational status of the migrant child labour portrayed a very grim picture. None of them was found going to the school and the reason behind their absenteeism was migration from other states. The child labour was belonging to the low income families. Children were engaged in various agricultural activities such as ploughing, sowing, irrigation, paddy transplantation, crop watching, cattle grazing, crop hartvesting wheatear picking stubble harvesting, pea plucking, cotton picking, potato digging, etc. Children were also employed in dairy farms and poultry farms. The wage earnings of working children were meagre. Special schools for migrants in the rural areas of the state can be opened where they may be taught through their mother tongue. Night schools or schools on the pattern of Charwaha Schools of Bihar may also be started to cater to the needs of working children. The study has also suggested that more employment avenues for adult labour, especially for the women in the villages of the state, should be generated through promoting agro-based industries and traditional handicrafts such as embroidery, pickle-papad making, etc.

Es ist die fünfte Coffee Lecture der Reihe mit dem Thema Open Science. "Open Science is the practice of science in such a way that others can collaborate and contribute, where research data, lab notes and other research processes are freely available, under terms that enable reuse, redistribution and reproduction of the research and its underlying data and methods." [Quelle] In dieser Coffee Lecture wird das Thema Open Science in allen Facetten und die Trends im Bereich Open Science beleuchtet. Ein verantwortungsvoller Umgang mit erhobenen Forschungsdaten und der sie erzeugenden Software dient dem Ziel der Nachvollziehbarkeit und Nachprüfbarkeit der Forschung. Er ermöglicht häufig eine Nachnutzung der Forschungsdaten und der Forschungssoftware. Open Science umfasst unter anderem Open Access, Open Data, Open Source und OER. Im Zusammenhang mit der Demokratisierung der Wissenschaft sind nachhaltige, nachnutzbare Forschungsdaten und darüber hinaus offene Bildungsmaterialien wichtige Aspekte. Der wissenschaftliche Wertschöpfungsprozess stellt Stufen des Forschungsprozesses dar. Die Ergebnisse der Forschung können von der Lehre aufgegriffen werden und einen Ausgangspunkt für neue Studien bilden. Der offene Zugang zu Forschungsergebnissen ist also in einer vernetzten Welt ganz grundlegend. Im Sinne von Open Science fördert die Forschungsdaten-Community deshalb die Transparenz von Wissenschaft beim Umgang mit Forschungsdaten nach dem Prinzip FAIR (findable, accessible, interoperable, reusable). Ein Public Engagement im Bereich der Forschung kann durch Open Science darüber hinaus noch gestärkt werden. "Wir müssen dahin kommen, dass man auch die eigenen Forschungsdaten anderen zur Verfügung stellt."

description: 162173 Ryugu, the target of Hayabusa2, has a round shape with an equatorial ridge, which is known as a spinning top-shape. A strong centrifugal force is a likely contributor to Ryugu's top-shaped features. Observations by Optical Navigation Camera onboard Hayabusa2 show a unique longitudinal variation in geomorphology; the western side of this asteroid, later called the western bulge, has a smooth surface and a sharp equatorial ridge, compared to the other side. Here, we propose a structural deformation process that generated the western bulge. Applying the mission-derived shape model, we employ a finite element model technique to analyze the locations that experience structural failure within the present shape. Assuming that materials are uniformly distributed, our model shows the longitudinal variation in structurally failed regions when the spin period is shorter than ~3.75 h. Ryugu is structurally intact in the subsurface region of the western bulge while other regions are sensitive to structural failure. We infer that this variation is indicative of the deformation process that occurred in the past, and the western bulge is more relaxed structurally than the other region. Our analysis also shows that this deformation process might occur at a spin period between ~3.5 h and ~3.0 h, providing the cohesive strength ranging between ~4 Pa and ~10 Pa.

description: Groundnut is a labour-intensive crop, especially for operations like sowing, weeding, harvesting, and drying. But, of-late, due to timely unavailability of labour, many farmers are not able to exercise timely operations resulting in low yield realization. The present study conducted in two major groundnut-growing states, viz. Gujarat and Andhra Pradesh, has revealed that farmers employ more human labour in weeding and harvesting operations in groundnut than in other operations. The practise of manual decortication and stripping is followed by a larger number of farmers in Andhra Pradesh than in Gujarat, indicating less mechanization in the former. For weeding, though, the human labour-use in weedicide + bullock intercultivation + hand weeding technique is almost half of that of the bullock inter-cultivation + hand weeding, only 13 per cent of the farmers practise this labour-saving technique and hence this method should be disseminated in both the regions to reduce human-labour demand. In Andhra Pradesh, for all the operations in groundnut cultivation except harvesting, the cost as well as labour-use has been reduced substantially due to use of partial/complete mechanization methods. Hence, the necessary infrastructure (labour-saving machineries) should be created at the village or block level to reduce the human-labour demand.

description: We present Keck II spectroscopy of an optical mHz quasi-periodic oscillations (QPOs) in the lightcurve of the X-ray pulsar binary Her X-1. In the power spectrum it appears as `peaked noise', with a coherency $\sim$2, a central frequency of 35 mHz and a peak-to-peak amplitude of 5%. However, the dynamic power spectrum shows it to be an intermittent QPO, with a lifetime of $\sim$hundred seconds, as expected if the lifetime of the orbiting material is equal to the thermal timescale of the inner disk. We have decomposed the spectral time series into constant and variable components and used blackbody fits to the resulting spectra to characterise the spectrum of the QPO variability and constrain possible production sites. We find that the spectrum of the QPO is best-fit by a small hot region, possibly the inner regions of the accretion disk, where the ballistic accretion stream impacts onto the disk. The lack of any excess power around the QPO frequency in the X-ray power spectrum, created using simultaneous lightcurves from XTE, implies that the QPO is not simply reprocessed X-ray variability.

description: The present study conducted in the Burdwan district of West Bengal, has examined the socio-economic impact of MGNREGA on the rural poor who are mainly comprised of small and marginal farmers & agricultural labourers. The study is based on a random sample of 102 respondents (82 beneficiary and 20 non-beneficiary households) drawn by the PPS method from two good-performing and two poorly-performing Gram Panchayats randomly selected from one randomly selected good-performing block in the district. It has been found that significant changes have taken place in the socio-economic variables like annual per capita income, monthly per capita food expenditure, annual per child expenditure on education, per capita savings, condition of the dwelling houses, access to healthcare facility and possession of other assets or luxury items for those households which are regularly working in the scheme. According to the value of the socio-economic index prepared, it has been found that in the initial year of implementation (2007-08) of MGNREGA in the study area, 43.9 per cent beneficiary households were in poor socio-economic conditions which have gradually improved in the succeeding years and decreased to 32.9 per cent in 2008-09 and further to 18.3 per cent in 2009-10. The study has made some suggestions also for incorporating improvements in the present MGNREG scheme based on the constraints reported by the workers associated with this Scheme.

Chemical Evolution of Odd Elements in an Inhomogeneous Early Galaxy

description: We investigate the chemical evolution of odd-numbered elements such as sodium (Na) and aluminum (Al) during the early epochs of the Galactic halo with the use of a model that reproduces the observed box-shaped distribution of extremely metal-poor stars in the [Na, Al/Mg] versus [Mg/H] plane. Our model is constructed under the assumptions that those stars retain the elemental abundance patterns produced by individual Type II supernovae (SNe), and that the yields of the odd elements depend on the initial metallicity, z, of their SN progenitors. As a result, recent abundance determinations that clarify how the [Na, Al/Mg] ratios of field stars have evolved to the solar values enable us to deduce how the yields of these odd elements depend on z. The observed trends in these abundances, in particular the very large scatter (over 1 dex in [Al/Mg]) requires that the Al yield scales as m_Al proportional to z^0.6 for [Mg/H]-1.8. It is found that the predicted frequency distribution of stars in the [Na/Mg] versus [Mg/H] diagram is very sensitive to the assumed form of the primordial IMF, and that its slope is steeper than the Salpeter IMF. The necessity to match the observed abundance patterns of odd elements and the frequency distribution of extremely metal-poor stars should provide useful constraints on nucleosynthesis calculations of metal-free massive stars as well as on theories of their formation.

description: We have studied self-conjugate second-order equations with spinor wavefunctions for fermions moving in an external Coulomb field. For stationary states, the equations are characterized by separated states with positive and negative energies, which render probabilistic interpretation possible. For the Coulomb field of attraction, the energy spectrum of the second-order equation coincides with the spectrum of the Dirac equation, while the probability densities of states are slightly different. For a Coulomb field of repulsion, there exists an impermeable potential barrier with radius depending on the classical electron radius and on the electron energy. The existence of the impermeable barrier does not contradict the results of experiment for determining the inner electron structure and does not affect (in the lowest order of perturbation theory) the Coulomb electron scattering cross section. The existence of the impermeable barrier can lead to positron confinement in supercritical nuclei with $Z \geq 170$ in case of realization of spontaneous emission of vacuum electron-positron pairs.

description: The technique of Darboux transformation is applied to nonlocal partner of two-dimensional periodic A_{n-1} Toda lattice. This system is shown to admit a representation as the compatibility conditions of direct and dual overdetermined linear systems with quantized spectral parameter. The generalization of the Darboux transformation technique on linear equations of such a kind is given. The connections between the solutions of overdetermined linear systems and their expansions in series at singular points neighborhood are presented.

description: The formation of patterned nanostructure in AgCo/Pt/MgO(001) thin film is simulated by a technique of combining molecular dynamics and phase-field theory. The dislocation (strain) network existing in Pt/MgO is used as a template whose pattern is transferred to AgCo phase in spinodal decomposition, resulting in regular arrays of Co islands that are attracted by the dislocations. The influence of various factors, such as component concentration and film thickness, is studied. It is found that the spinodal decomposition of AgCo in this system is mainly characterized by a competition between a surface-directed layer structure and the strain-induced patterned structure, where the patterned Ag-Co structure only dominates in a small range near the interface (less than 10 atomic layers). However, if the interlayer diffusion can be minimized by controlling film growth conditions, it is shown that the patterned structure can be formed throughout the entire film.

 Type species. Protomorgania koebelei Dooley and Evans, sp. nov.
 Diagnosis. Protomorgania Dooley and Evans is a monotypic genus that belongs to the subfamily Aspidiotinae based on presence of macroducts of the 1-barred type. Unlike many of the aspidiotine genera, it has perispiracular pores associated with the spiracles. It is similar to several of the genera treated herein in that they have a relatively broad body with a constriction or incision between the prothorax and mesothorax with most of the species in this group lack perivulvar pores. It can be distinguished from these genera by the following combination of characters: anterior and posterior spiracles with associated perispiracular pores; dorsum of the pygidium not reticulated; L 1 lobes fused ventrally, appressed dorsally. It is most similar to Neomorgania (MacGillvray, 1921) but can be distinguished from that genus by having: the anterior and posterior spiracles with associated pores; L 1 lobes fused ventrally, appressed dorsally; and a tubercle present on lateral margin of the cephalon; in Neomorgonia, only the anterior spiracles have associated pores; the L 1 lobes are appressed ventrally and dorsally; and it lacks the tubercle on lateral margin of the cephalon.

description: In India, male out-migration from rural to urban areas has increased in recent years, especially in the Indo- Gangetic regions of the country. This indicates that most of the developed regions of India are utilizing labour force of backward areas. The paper has investigated on labour out-migration from the states of Uttar Pradesh and Bihar to find its determinants and its impacts on farm economy. The analysis of determinants shown that the number of members in a family and their educational status have a positive impact on migration. As a result of male out-migration, the women left behind in the villages assume a major role in various farm activities resulting in the so-called ‘feminization of agriculture’. It has also empowered the female members of the migrant households in terms of enhancing their decision-making role in various activities. The study has observed some policy implications in terms of formation of self-help groups or labour societies to help out-migrants, organization of training programmes for capacity building of women, more thrust on education a girl-child and development of infrastructure in the rural areas.

description: We report on a multi-wavelength study of the relationship between young star clusters in the Antennae galaxies (NGC 4038/9) and their interstellar environment, with the goal of understanding the formation and feedback effects of star clusters in merging galaxies. This is possible for the first time because various new observations (from X-rays to radio wavelengths) have become available in the past several years. Quantitative comparisons are made between the positions of the star clusters (broken into three age groups) and the properties of the interstellar medium by calculating the two-point correlation functions. We find that young star clusters are distributed in a clustered fashion. The youngest star clusters are associated with molecular cloud complexes with characteristic radii of about 1 kpc. In addition, there is a weak tendency for them to be found in regions with higher HI velocity dispersions. No dominant triggering mechanism is identified for the majority of the clusters in the Antennae. Feedback from young bright cluster complexes show large H_alpha bubbles and H_alpha velocity gradients in shells around the complexes. We estimate the current star formation rate to be 20 solar mass/yr, and the gas consumption timescale to be 700 Myr. The latter is comparable to the merging time scale and indicates that star formation has been enchanced by the merger event. Finally, we find that the Schmidt law, with index N=-1.4, is also a good description of the cluster formation triggered by merging in the Antennae. There is some evidence that feedback effects may modify the Schmidt law at scales below 1 kpc.

An ensemble of symmetric unistochastic matrices is obtained with use of unitary symmetric matrices pertaining to the circular orthogonal ensemble. We study the distribution of complex eigenvalues of bistochastic, unistochastic and ortostochastic matrices in the complex plane. We compute averages (entropy, traces) over the ensembles of unistochastic matrices and present inequalities concerning the entropies of products of bistochastic matrices.

description: Quantum entanglement is a form of correlation between quantum particles that cannot be increased via local operations and classical communication. It has therefore been proposed that an increment of quantum entanglement between probes that are interacting solely via a mediator implies non-classicality of the mediator. Indeed, under certain assumptions regarding the initial state, entanglement gain between the probes indicates quantum coherence in the mediator. Going beyond such assumptions, there exist other initial states which produce entanglement between the probes via only local interactions with a classical mediator. In this process the initial entanglement between any probe and the rest of the system "flows through" the classical mediator and gets localised between the probes. Here we theoretically characterise maximal entanglement gain via classical mediator and experimentally demonstrate, using liquid-state NMR spectroscopy, the optimal growth of quantum correlations between two nuclear spin qubits interacting through a mediator qubit in a classical state. We additionally monitor, i.e., dephase, the mediator in order to emphasise its classical character. Our results indicate the necessity of verifying features of the initial state if entanglement gain between the probes is used as a figure of merit for witnessing non-classical mediator. Such methods were proposed to have exemplary applications in quantum optomechanics, quantum biology and quantum gravity.

Although the primary response to chemotherapy is high, the majority of patients will develop resistance against applied treatment. In this study, we focused on resistance to cisplatin, a first-line drug used for the treatment of ovarian cancer. The mechanism of the resistance development process is widely described, but there is a lack of information about the involvement of members of small heat shock proteins (HSPs) and their transport via exosomes. In this study, we used two cell lines: A2780 and SKOV3, and their cisplatin-resistance variants: A2780 CDDP and SKOV3 CDDP. We have shown that the expression of three small HSPs (HSPB5, HSPB6, and HSPB8) in cisplatin-resistant cell lines differs from their sensitive counterparts. Further, we isolated exosomes and determined the small HSPs in their cargo. In A2780 WT we observed a low amount of HSPB5 and HSPB6. We did not observe the expression of small HSPs in the SKOV3 cell line in both sensitive and resistant variants. Our data suggest the involvement of small HSPs in drug resistance of ovarian cancer and their presence is not related to exosomal transport. Analysis of the biological consequences of the imbalance of small HSPs expression in cisplatin resistance needs further investigation.

description: In Punjab, the influx of migrant labour particularly in agriculture sector started with the green revolution and picked up subsequently. Due to monoculture in the cropping pattern, the state has become largely dependent on migrant labourers for various agricultural operations. The influx of seasonal as well as permanent labour from outside has led to various socio-economic problems in Punjab. In the wake of this, the present study was purposively conducted in the Central Zone of Punjab for the year 2011 to find the causes and impact of labour in-migration in Punjab. A total of 105 respondents belonging to the states of Bihar, Uttar Pradesh, Jharkhand, Madhya Pradesh and Nepal constituted the sample frame. The results have revealed that better income and employment opportunities at the destination place were the major factors responsible for migration. About 64 per cent of the respondents earned less than ` 20000 per annum at their native places and 60 per cent of them had less than 200 days of employment in a year, whereas 23 per cent of the labourers were unemployed at their native place. However, after migration 63 per cent of the migrants could earn from ` 20000 to ` 50000 per annum and 34 per cent earned more than ` 50000 per annum in Punjab, leading to a major share (60% of total income) as remittances sent back to their native places. On the other hand, the flip side of the influx of migrants in the study area increased the drug menace by 37 per cent, social tension by 45 per cent and crime by 43 per cent. The state government should maintain a demographic balance by regulating the migrants and should help in verification of credentials of migrating labourers to Punjab.

description: We report measurements of the 12C/13C abundance ratio in the three galactic regions G 333.0-0.4, NGC 6334 A and G 351.6-1.3 from observations of the 12CI 3P2-3P1 transition and the hyperfine components of the corresponding 13CI transition near 809 GHz. These transitions were observed simultaneously with the CO 7-6 line emission at 806 GHz with the AST/RO telescope located at the South Pole. From a simultaneous fit to the 12CI 3P2-3P1 transition and the HF components of the corresponding 13CI transition and an independent estimate of an upper limit to the optical depth of the 12CI emission we determine intrinsic 12CI/13CI column density ratios of 23+-1 for G 333.0-0.4, 56+-14 for NGC 6334 A and 69+-12 for G 351.6-1.3. As the regions observed are photon dominated, we argue that the apparent enhancement in the abundance of 13C towards G 333.0-0.4 may be due to strong isotope-selective photodissociation of 13CO, outweighing the effects of chemical isotopic fractionation as suggested by models of PDRs. Towards NGC 6334 A and G 351.6-1.3 these effects appear to be balanced, similar to the situation for the Orion Bar region observed by Keene et al. (1998).

description: No-cloning theorem forbids perfect cloning of an unknown quantum state. A universal quantum cloning machine (UQCM), capable of producing two copies of any input qubit with the optimal fidelity, is of fundamental interest and has applications in quantum information processing. This is enabled by delicately tailored nonclassical correlations between the input qubit and the copying qubits, which distinguish the UQCM from a classical counterpart, but whose experimental demonstrations are still lacking. We here implement the UQCM in a superconducting circuit, and investigate these correlations. The measured entanglements well agree with our theoretical prediction that they are independent of the input state and thus constitute a universal quantum behavior of the UQCM that was not previously revealed. Another feature of our experiment is the realization of deterministic and individual cloning, in contrast to previously demonstrated UQCMs, which either were probabilistic or did not constitute true cloning of individual qubits.

description: The experience gained from the path breaking experiment of formation of labour bank has been reported and SWOT analysis has been carried out. The strengths, weaknesses, opportunities and threats of the Labour Bank have been reported. The capital of Labour Bank is the working capacity of the registered labourers. The Bank lends, even though for a short period, the working capacity of the labourers. The significance of Labour Bank experiment lies in the need of the agricultural sector to break the shackles on account of labour-related problems. The experience gained from this experiment can be used to develop similar labour organizations in other panchayaths also. The study has offered some suggestions based on the Labour Bank in Kunnathukal Panchayath in Thiruvananthapuram district of Kerala and its current relevance for implementation of rural employment programmes.

description: We study double ionization of He driven by a near-single-cycle laser pulse at low intensities at 400 nm. Using a three-dimensional semiclassical model, we identify the pathways that prevail non-sequential double ionization (NSDI). We focus mostly on the delayed pathway, where one electron ionizes with a time-delay after recollision. We have recently shown that the mechanism that prevails the delayed pathway depends on intensity. For low intensities slingshot-NSDI is the mechanism that prevails. Here, we identify the differences in two-electron probability distributions of the prevailing NSDI pathways. This allows us to identify properties of the two-electron escape and thus gain significant insight into slingshot-NSDI. Interestingly, we find that an observable fingerprint of slingshot-NSDI is the two electrons escaping with large and roughly equal energies.

description: We present Chandra data from a 31.7 ks observation of the Centaurus cluster, using the ACIS-S detector. Images of the X-ray emission show a plume-like feature at the centre of the cluster, of extent 60 arcsec (20 kpc in projection). The feature has the same metallicity as gas at a similar radius, but is cooler. Using adaptive binning, we generate temperature, abundance and absorption maps of the cluster core. The radial abundance profile shows that the previously known, steep abundance gradient peaks with a metallicity of 1.3-1.8 Zsolar at a radius of about 45 arcsec (15 kpc), before falling back to 0.4 Zsolar at the centre of the cluster. A radial temperature profile shows that the temperature decreases inwards. We determine the spatial distributions of each of two temperature components, where applicable. The radiative cooling time of the cooler component within the inner 10 arcsec (3 kpc) is less than 2x10^7 yr. X-ray holes in the image coincident with the radio lobes are seen, as well as two outer sharp temperature drops, or cold fronts. The origin of the plume is unclear. The existence of the strong abundance gradient is a strong constraint on extensive convection or gas motion driven by a central radio source.

description: We study the connections between three quantities that can be used as diagnostics for quantum chaos, i.e., the out-of-time-order correlator (OTOC), Loschmidt echo (LE), and complexity. We generalize the connection between OTOC and LE for infinite dimensions and extend it for higher-order OTOCs and multi-fold LEs. Novel applications of this intrinsic relation are proposed. We also propose a relationship between a specific circuit complexity and LE by using the inverted oscillator model. These relationships signal a deeper connection between these three probes of quantum chaos.
