description: Nanometer scale power amplifiers (PA) at sub-THz suffer from severe parasitic effects that lead to experience limited maximum frequency and reduced power performance at the device transceiver front end. The integrated circuits researchers proposed different PA design architecture combinations at scaled down technologies to overcome these limitations. Although the designs meet the minimum requirements, the power added efficiency (PAE) of PA is still quite low. In this paper, a W-band single-ended common-source (CS) and cascode integrated 3-stage 2-way PA design is proposed. The design integrated different key design methodologies to mitigate the parasitic; such as combined Class AB and Class A stages for gain-boosting and efficiency enhancement, Wilkinson power combiner for higher output power, linearity, and bandwidth, and transmission line (TL)-based wide band matching network for better inter-stage matching and compact size. The proposed PA design is validated using UMS 150-nm GaAs pHEMT using advanced design system (ADS) simulator. The results show that the proposed PA achieved a gain of 20.1 dB, an output power of 17.2 dBm, a PAE of 33 % and a 21 GHz bandwidth at 90 GHz Sub-THz band. The PA layout consumes only 5.66 X 2.51 mm2 die space including pads. Our proposed PA design will boost the research on sub-THz integrated circuits research and will smooth the wide spread adoption of 6G in near future.

 Extremely rare within the Kimberley region, Melanotaenia nigrans is only known from one small tributary in Dominic Creek near the mouth of the King Edward River (Fig. 21), and although WAM records suggest it is present in Yampi Sound, recent examination of these specimens by the senior author revealed them to be M. australis. The species is also found in coastal drainages of the Northern Territory, including Groote Eylandt and the northern tip of Cape York (Allen et al. 2002).

description: Baseline liver stiffness (LS) is prognostically relevant in patients with chronic hepatitis C virus (HCV) infection but may change after successful HCV eradication. Data on post-treatment LS for a further risk stratification remain scarce. Here, we study the kinetics of LS and laboratory parameters in patients undergoing HCV treatment and analyze the association of post-treatment LS with outcome parameters. In a cohort of 1011 chronic HCV patients undergoing DAA treatment, we identified 404 patients with sequential LS and laboratory assessments with or without viral eradication. Additionally, outcome parameters were correlated with post-treatment LS after successful HCV therapy. LS significantly decreased from a median of 8.8 to 6.1 kPa in 346 patients after HCV eradication, but significantly increased from a median of 10.5 to 11.9 kPa in 58 patients without viral clearance. In 78 patients with two sequential post-treatment measurements, LS decreased from 12.6 to 8.7 kPa after a median 344 d, with a further decrease to 7.0 kPa after a median of 986 d after end of treatment (EoT). In 400 patients with a post-treatment LS assessment after viral eradication, only 9 liver-related events occurred over a median follow-up (FU) of 23 months. All events were observed in patients with a post-treatment LS >20 kPa. After successful HCV eradication, LS improves sequentially, suggesting an initial phase of necroinflammation regression followed by a second phase of true fibrosis regression. Overall, liver-related events were rarely observed and seem to be limited to patients with a post-treatment LS >20 kPa, so that these patients require a closer clinical monitoring.

description: Phase transformations such as freezing typically start with heterogeneous nucleation. Heterogeneous nucleation near a wetting transition, of a crystalline phase is studied. The wetting transition occurs at or near a vapour-liquid transition which occurs in a metastable fluid. The fluid is metastable with respect to crystallisation, and it is the crystallisation of this fluid phase that we are interested in. At a wetting transition a thick layer of a liquid phase forms at a surface in contact with the vapour phase. The crystalline nucleus is then immersed in this liquid layer, which reduces the free energy barrier to nucleation and so dramatically increases the nucleation rate. The variation in the rate of heterogeneous nucleation close to wetting transitions is calculated for systems in which the longest-range forces are dispersion forces.

description: We present a measurement of the spatial clustering of rest-frame UV-selected massive galaxies at $0.5\le z \le 2.5$ in the COSMOS/UltraVISTA field. Considering four separate redshift bins with $Δz=0.5$, we construct three galaxy populations, i.e., red sequence (RS), blue cloud (BC), and green valley (GV) galaxies, according to their rest-frame extinction-corrected UV colors. The correlation lengths of these populations are confirmed to be dependent on their rest-frame UV color and redshift: UV redder galaxies are found to be more clustered. In all redshift bins, the GV galaxies generally have medium clustering amplitudes and are hosted within dark matter halos whose masses are more or less between those of RS and BC galaxies; and the clustering amplitude of GV galaxies is close to that of AGNs in the same redshift bin, suggesting that AGN activity may be responsible for transforming galaxy colors. After carefully examining their stellar masses, we find that the clustering amplitudes of galaxy samples with different colors are all similar once they have a similar median stellar mass and that the median stellar mass alone may be a good predictor of galaxy clustering.

description: A great transformation is under way in international relations. The influence of non-state actors is rising, and the focus of intergovernmental coordination is shifting from border measures, such as tariffs, to a myriad of policies that traditionally have been the sole province of national decision making, such as food safety standards. This transformation is most evident where international cooperation has been most successful: international trade, in particular the efforts within the World Trade Organization (WTO) to manage non-tariff barriers to trade. In many cases it has proved extremely difficult for nations to comply with WTO strictures on non-tariff policies because these policies are embedded within an array of political supporters and institutions that democratic governments find difficult (and politically costly) to unravel. We focus on these “problem cases”—where the goal of liberalizing trade conflicts with popular consumer preferences—and suggest that these pose a threat to the legal integrity and political sustainability of the WTO. Ironically, cases marked by relatively low economic stakes may pose the greatest threats because these cases are less likely to be linked to other important benefits of international cooperation, and thus governments are less likely to seek an intergovernmental solution to avert non-compliance in such situations. We suggest that formal remedies to this problem are unlikely to be successful; rather, restraint by key states is likely to be the most effective way for the world trading community to learn to avoid and abate these problem cases before they overwhelm the world trading system.

description: Identifying mechanisms to finance environmental conservation is crucial to achieve sustainable development. Pharmaceutical prospecting has been touted as a mechanism with prospects to generate revenue to conserve biodiversity. Pharmaceutical prospecting could improve with the use of prior information to guide pharmaceutical prospecting research. Such prior information could be traditional knowledge on use of biodiversity for medicinal purposes. Sri Lanka is richly bestowed with both biodiversity and traditional knowledge of the use of it for medicinal purposes. This paper, through review of the literature and empirical estimation of the willingness to pay for pharmaceutical prospecting, has estimated the complementary value of biodiversity and traditional knowledge of its use, in Sri Lanka. The Knuckles forest has been used as the demonstrative case for analysis. It is found that pharmaceutical prospecting has reasonable potential to generate revenue to conserve biodiversity in Sri Lanka. Thus, it is recommended that legislations, institutions and mechanisms, which are required to establish property rights on biodiversity and traditional knowledge, be expeditiously established to facilitate pharmaceutical prospecting. Given the social and political sensitivity of pharmaceutical prospecting, broad public consultation should be sought, prior to implementation of pharmaceutical prospecting.

description: The Newman-Penrose constants of the spacetime corresponding to the development of the Brill-Lindquist initial data are calculated by making use of a particular representation of spatial infinity due to H. Friedrich. The Brill-Lindquist initial data set represents the head-on collision of two non-rotating black holes. In this case one non-zero constant is obtained. Its value is given in terms of the product of the individual masses of the black holes and the square of a distance parameter separating the two black holes. This constant retains its value all along null infinity, and therefore it provides information about the late time evolution of the collision process. In particular, it is argued that the magnitude of the constants provides information about the amount of residual radiation contained in the spacetime after the collision of the black holes.

description: The recent emerging field of synthetic dimension in photonics offers a variety of opportunities for manipulating different internal degrees of freedom of photons such as the spectrum of light. While nonlinear optical effects can be incorporated into these photonic systems with synthetic dimensions, these nonlinear effects typically result in long-range interactions along the frequency axis. Thus it has been difficult to use of the synthetic dimension concept to study a large class of Hamiltonians that involves local interactions. Here we show that a Hamiltonian that is locally interacting along the synthetic dimension can be achieved in a dynamically-modulated ring resonator incorporating $χ^{(3)}$ nonlinearity, provided that the group velocity dispersion of the waveguide forming the ring is specifically designed. As a demonstration we numerically implement a Bose-Hubbard model, and explore photon blockade effect, in the synthetic frequency space. Our work opens new possiblities for studying fundamental many-body physics in the synthetic space in photonics, with potential applications in optical quantum communication and quantum computation.
Imaging Spectroscopy for Extrasolar Planet Detection

Subjects: subject: Astrophysics (astro-ph)

description: Coronagraphic imaging in combination with moderate to high spectral resolution may prove more effective in both detecting extrasolar planets and characterizing them than a standard coronagraphic imaging approach. We envisage an integral-field spectrograph coupled to a coronagraph to produce a 3D datacube. For the idealised case where the spectrum of the star is well-known and unchanging across the field, we discuss the utility of cross-correlation to seek the extrasolar planet signal, and describe a mathematical approach to completely eliminate stray light from the host star (although not its Poisson noise). For the case where the PSF is dominated by diffraction and scattering effects, and comprises a multitude of speckles within an Airy pattern typical of a space-based observation, we turn the wavelength dependence of the PSF to advantage and present a general way to eliminate the contribution from the star while preserving both the flux and spectrum of the extrasolar planet. We call this method `spectral deconvolution'. We illustrate the dramatic gains by showing an idealized simulation that results in a 20-sigma detection of a Jovian planet at 2 pc with a 2-m coronagraphic space telescope, even though the planet's peak flux is only 1% that of the PSF wings of the host star. This scales to detection of a terrestrial extrasolar planet at 2 pc with an 8-m coronagraphic Terrestrial Planet Finder (TPF) in ~7 hr (or less with appropriate spatial filtering). Data on the spectral characteristics of the extrasolar planet and hence on its atmospheric constituents and possible biomarkers are obtained naturally as part of this process.

description: Environmental policies to deal with global problems like climate change must be global and some form of environmental valuation at the international level would be a very useful input into decision making. However, such a valuation is likely to be so difficult that we need to consider whether it is possible at all. The purpose of this paper was to investigate how people in different socioeconomic settings and different countries view and value a number of environmental issues. We set out to see how people in widely different settings would rank different “environmental problems”. The study was performed simultaneously in countries from four continents; Botswana, Brazil, Kenya, South Africa, Sri Lanka, Sweden and Uganda. The sample of countries varies by income, population growth, social indicators such as literacy and environmental resources. We found that most of the respondents were reasonably aware of environmental issues and there is a similar group of issues that dominates the environmental agenda in practically all the countries. There is for instance agreement on the fact that water and air pollution as well as waste management are important issues. Issues such as climate change, forest loss and the spread of toxic substances were also considered important in practically all countries. The results have proven to be reasonably in line with what might be expected.

description: We propose novel hybrid beamforming schemes for the terahertz (THz) wireless system where a multi-antenna base station (BS) communicates with a multi-antenna user over frequency selective fading. Here, we assume that the BS employs sub-connected hybrid beamforming and multi-carrier modulation to deliver ultra high data rate. We consider a three-dimensional wideband THz channel by incorporating the joint effect of molecular absorption, high sparsity, and multi-path fading, and consider the carrier frequency offset in multi-carrier systems. With this model, we first propose a two-stage wideband hybrid beamforming scheme which includes a beamsteering codebook searching algorithm for analog beamforming and a regularized channel inversion method for digital beamforming. We then propose a novel wideband hybrid beamforming scheme with two digital beamformers. In this scheme, an additional digital beamformer is developed to compensate for the performance loss caused by the constant-amplitude hardware constraints and the difference of channel matrices among subcarriers. Furthermore, we consider imperfect channel state information (CSI) and propose a probabilistic robust hybrid beamforming scheme to combat channel estimation errors. Numerical results demonstrate the benefits of our proposed schemes for the sake of practical implementation, especially considering its high spectral efficiency, low complexity, and robustness against imperfect CSI.

description: In order to achieve full detection sensitivity at low frequencies, the mirrors of interferometric gravitational wave detectors must be isolated from seismic noise. The VIRGO vibration isolator, called 'superattenuator', is fully effective at frequencies above 4 Hz. Nevertheless, the residual motion of the mirror at the mechanical resonant frequencies of the system are too large for the interferometer locking system and must be damped. A multidimensional feedback system, using inertial sensors and digital processing, has been designed for this purpose. An experimental procedure for determining the feedback control of the system has been defined. In this paper a full description of the system is given and experimental results are presented.

description: Malnutrition among children and women continues to be one of the major problems in Sri Lanka despite the food and nutritional intervention programs implemented since independence. The objectives of this study were to find out whether there is calorie malnutrition among the urban poor in Kandy and to find out the determinants of the intra-household allocation of calories. Calorie adequacy ratios of fathers, mothers and children were compared to find out whether there is calorie malnutrition among family members. Relative calorie allocation of individuals was regressed with socio-economic variables to find the determinants of the intra-household calorie allocation. Primary data collected using a structured questionnaire from sixty households in the lower income group in urban Kandy was used for the analysis. Results show that there was a significant difference among calorie adequacy ratios of fathers, mothers and children. Fathers have the highest and children have the lowest mean calorie adequacy ratios. Regression results indicate that income of mother and family size have significant positive and negative impacts respectively on mother’s relative calorie allocation. Results also show that there was an age and gender biased calorie allocation within the family. Income of mother had a negative effect on children’s calorie allocation. Though expansion in employment opportunities could alleviate malnutrition among women, it may aggravate malnutrition among children.

We express this quantum curve in terms of spectral Darboux coordinates on the moduli space of meromorphic $\mathfrak{sl}_2$-connections on $\mathbb{P}^1$ and argue that the topological recursion produces a $2g$-parameter family of associated tau functions, where $2g$ is the dimension of the moduli space considered. We apply this procedure to the 6 Painlevé equations which correspond to $g=1$ and consider a $g=2$ example.

description: Finite temperature simulations are used to study quadrupole excitations of a trapped Bose-Einstein condensate. We focus specifically on the m=0 mode, where a long-standing theoretical problem has been to account for an anomalous variation of the mode frequency with temperature. We explain this behavior in terms of the excitation of two separate modes, corresponding to coupled motion of the condensate and thermal cloud. The relative amplitudes of the modes depends sensitively on the temperature and on the frequency of the harmonic drive used to excite them. Good agreement with experiment is found for appropriate drive frequencies.

Research universities in search of our kind of people: Black women doctoral student socialization
Creators: name: Cunningham, Shari M.
Publisher: name: No Publisher Supplied

description: As research universities become more visibly “diverse,” scholarship must contend with whether inclusion is also a part of higher education’s future. This project examines doctoral education's attitudes, beliefs, and ideologies as a site of persistent exclusionary practices and impetus for enduring change. It has been documented that knowing how to navigate academia's social dynamics is one of the most critical lessons doctoral students learn. Hence, this project focused on the social aspects of doctoral training, seeking to move beyond quantifiable benchmarks. This research project explored the lived experience of Black women doctoral students in Ph.D. programs in the Humanities at research universities. Data collection included semi-structured interviews examining the experience of Black women doctoral students enrolled or formerly enrolled at three R1 public universities in New England, the Mid-Atlantic, and the Southern United States from across 10 disciplines. Three research questions guided this project, covering the perception of academic socialization, relationship building, and the history of the universities as racialized organizations. Three significant findings from my project include (1) the significance of the advisor/advisee relationship; (2) Black women’s experiences were informed by racialized/gendered ideologies; and (3) the (mis)alignment of beliefs between the advisor and advisee complicated relationship dynamics and access to resources.

Soon, 5G mobile networks will be available to handle all types of services and applications for vast numbers of users through their mobile equipment. To effectively manage new 5G systems, end-to-end (E2E) performance analysis and optimization will be key features. However, estimating the end-user experience is not an easy task for network operators. The amount of end-user performance information operators can measure from the network is limited, complicating this approach. Here we explore the calculation of service metrics [known as key quality indicators (KQIs)] from classic low-layer measurements and parameters. We propose a complete machine-learning (ML) modeling framework. This system's low-layer metrics can be applied to measure service-layer performance. To assess the approach, we implemented and evaluated the proposed system on a real cellular network testbed.

description: We study an impact of asymmetric dark matter on properties of the neutron stars and their ability to reach the two solar masses limit, which allows us to present a new range of masses of dark matter particles and their fractions inside the star. Our analysis is based on the observational fact of the existence of two pulsars reaching this limit and on the theoretically predicted reduction of the neutron star maximal mass caused by the accumulation of dark matter in its interior. We also demonstrate that light dark matter particles with masses below 0.2 GeV can create an extended halo around the neutron star leading not to decrease, but to increase of its visible gravitational mass. By using recent results on the spatial distribution of dark matter in the Milky Way, we present an estimate of its fraction inside the neutron stars located in the Galaxy center. We show how the detection of a 2 Msun neutron star in the most central region of the Galaxy will impose an upper constraint on the mass of dark matter particles of ~ 60 GeV. Future high precision measurements of the neutron stars maximal mass near the Galactic center, will put a more stringent constraint on the mass of the dark matter particle. This last result is particularly important to prepare ongoing, and future radio and x-ray surveys.

description: Organic products are considered to be superior in quality compared to conventionally produced products, since it has been proved that organic products help prevent several health hazards. Therefore, demand for organic products are increasing all over the world, as well as in Sri Lanka. Given this increasing demand for organic products, this study was conducted with a view to identifing the market potentials for organic products and consumer expectations in Kandy. Further, it identifies the factors that influence the additional willingness to pay for organic vegetables. The research was conducted in three supermarkets, namely, Cargills, Dhanasiri and Royal Garden Mall. Thirty respondents were randomly selected from each of the supermarkets. Results reveal that most of the consumers are aware of organic products and this awareness has influenced their consumption of organic products in the past. Further, a majority of the consumers considered price as an important factor for their organic product consumption and have attached a higher importance for certification from a reputed organization. Consumers also indicated that organic products should be sold in easily accessible shops for the convenience of purchasing. Results of the regression analysis revealed that of the socio-demographic factors, income, environmental education and years of education significantly influence the willingness to pay for organic vegetables. Based on the study it could be concluded that consumer awareness effectively advances the demand for organic products and there is a high potential to introduce organic products to the supermarkets in Kandy. Therefore, along with introducing organic products, marketers should also direct proper awareness programs among consumers in promoting the demand for organic products.

description: The NJ tree inferred from the sheep and human TRAV gene sequences. The evolutionary analysis was conducted in MEGA5 [36]. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) is shown next to the branches [40]. The trees are drawn to scale, with branch lengths in the same units as those of the evolutionary distances used to infer the phylogenetic trees. The evolutionary distances were computed using the p-distance method [37] and are in the units of the number of base differences per site. The sheep TRAV subgroup classification is according to the corresponding human TRAV subgroups. Sheep-specific subgroups are numbered from TRAV42 (boxed in the right column). The TRAV genes found in humans and not in sheep are boxed in the tree. The gene functionality according to IMGT rules (F: functional, ORF: open reading frame, P: pseudogene) is indicated. For each subgroup, the CDR1-IMGT, CDR2-IMGT and CDR3-IMGT lengths are reported between brackets in the right column: when different between species, the first is for the human subgroup and the second is for the sheep subgroup. For TRAV42 to TRAV45, the CDR-IMGT lengths are for the sheep subgroup only (no corresponding subgroup in humans). The IMGT 6-letter standardised abbreviation for taxon is used: three letters for genus and three letters for species (Homsap, Oviari). (PPT 7.56 kb)

description: The number of air transportation passengers during the holidays in Brazil has grown notably since the late nineties. One of the reasons is greater competition in airfares made possible by economic liberalization. This paper presents an econometric model of airline pricing aiming at estimating the impacts of holiday periods on fares, with special emphasis on three-day holiday events. It makes use of a database with daily collected data from the internet between 2008 and 2010 for the major Brazilian city, Sao Paulo. The econometric panel data model employs a two-way error components "within" estimator, controlling for airline/airport-pair fixed effect along with quotation and departure months effects. The decomposition of time effects between quotation and departure month effects is the main methodological contribution of the paper. Results allow for a comparative analysis of the performance of Sao Paulo's downtown and international airports - respectively, Congonhas (CGH), and Guarulhos (GRU) airports. As a result, the price of tickets bought 60 days in advance for flights with two stops leaving from the downtown airport fell by most.

description: In this paper we introduce a biologically inspired Convolutional Neural Network (CNN) architecture called LGN-CNN that has a first convolutional layer composed by a single filter that mimics the role of the Lateral Geniculate Nucleus (LGN). The first layer of the neural network shows a rotational symmetric pattern justified by the structure of the net itself that turns up to be an approximation of a Laplacian of Gaussian (LoG). The latter function is in turn a good approximation of the receptive field profiles (RFPs) of the cells in the LGN. The analogy with the visual system is established, emerging directly from the architecture of the neural network. A proof of rotation invariance of the first layer is given on a fixed LGN-CNN architecture and the computational results are shown. Thus, contrast invariance capability of the LGN-CNN is investigated and a comparison between the Retinex effects of the first layer of LGN-CNN and the Retinex effects of a LoG is provided on different images. A statistical study is done on the filters of the second convolutional layer with respect to biological data. In conclusion, the model we have introduced approximates well the RFPs of both LGN and V1 attaining similar behavior as regards long range connections of LGN cells that show Retinex effects.

description: This paper presents a test of intermodal interaction between coaches and airlines in Brazil in order to check for the efficacy of recent liberalization measures designed to promote competition in both industries. Interstate travel service in the country is heavily provided by coaches, and the system is fully operated by the private sector under public delegation through permits and authorizations. Agency-based regulation was introduced in 2002 along with a price cap regime aimed at enhancing the flexibility to change fares in response to demand and cost conditions. By making use of a reaction function-based model of coach operators' pricing decisions in the interstate travel market, we then estimate the sensitivity of the changes in coach fares to the changes in airline fares in a simultaneous-equation framework. Intermodal interaction among coach operators and airlines is found to be highly significant and probably due to the competition for a small but increasing set of premium, quality-sensitive, coach passengers.

description: The two-dimensional (2D) vortex lattice in the extreme type-II limit is studied by Monte Carlo simulation of the corresponding 2D Coulomb gas, with identical pins placed at sites coinciding with the zero-temperature triangular vortex lattice. At weak pinning we find evidence for 2D melting into an intermediate hexatic phase. The strong pinning regime shows a Kosterlitz-Thouless transition, driven by interstitial vortex/anti-vortex excitations. A stack of such identical layers with a weak Josephson coupling models a layered superconductor with a triangular arrangement of columnar pins at the matching field. A partial duality analysis finds that layer decoupling of the flux-line lattice does not occur at weak pinning for temperatures below 2D melting.
