description: From CCD observations carried out with different telescopes, we present short-term photometric measurements of the large trans-Neptunian object Varuna in 10 epochs, spanning around 19 years. We observe that the amplitude of the rotational light-curve has changed considerably during this period of time from 0.41 to 0.55 mag. In order to explain this variation, we constructed a model in which Varuna has a simple triaxial shape, assuming that the main effect comes from the change of the aspect angle as seen from Earth, due to Varuna's orbital motion in the 19-year time span. The best fits to the data correspond to a family of solutions with axial ratios b/a between 0.56 and 0.60. This constrains the pole orientation in two different ranges of solutions presented here as maps. Apart from the remarkable variation of the amplitude, we have detected changes in the overall shape of the rotational light-curve over shorter time scales. After the analysis of the periodogram of the residuals to a 6.343572 h double-peaked rotational light-curve fit, we find a clear additional periodicity. We propose that these changes in the rotational light-curve shape are due to a large and close-in satellite whose rotation induces the additional periodicity. The peak-to-valley amplitude of this oscillation is in the order of 0.04 mag. We estimate that the satellite orbits Varuna with a period of 11.9819 h (or 23.9638 h), assuming that the satellite is tidally locked, at a distance of ~ 1300 km (or ~ 2000 km) from Varuna, outside the Roche limit.

description: We prove an adiabatic theorem for the evolution of spectral data under a weak additive perturbation in the context of a system without an intrinsic time scale. For continuous functions of the unperturbed Hamiltonian the convergence is in norm while for a larger class functions, including the spectral projections associated to embedded eigenvalues, the convergence is in the strong operator topology.

description: The study examined the profitability of livestock marketing in Gamawa Local Government Area, Bauchi State in the year 2012. A combination of both purposive and simple random sampling techniques was employed to collect data from one hundred and twenty marketers, using structured questionnaire. The data were analysed using descriptive statistics, farm budgeting and multiple regression analysis. The result showed that goat and cattle marketers had the mean age, marketing experience and household size of 46 and 40 years, 11 and 13 years, 9 and 13 persons, respectively. In addition, marketing margin and returns per Naira invested per goat and cattle in the study area were N 4,016.66 and N38, 816.6, and N0.14 and N0.26, respectively. The findings revealed that cost of goat acquisition, medication, and labour were significant at P ≤ 0.01, P ≤ 0.05 and P ≤ 0.1, respectively; while in the case of cattle marketing, cost of cattle acquisition, feeding, medication, and labour were significant at P ≤ 0.01, P ≤ 0.05, P ≤ 0.1 and P ≤ 0.1, respectively. The study identified inadequate credit facilities, lack of market information, high cost of transportation and inadequate housing facilities as the most pressing constraints affecting the system. It was therefore recommended that provision of adequate housing facilities, sources of market information and easing access to credits as well as lowering transportation costs in order to improve in the areas of shortcoming.
EFFECT OF MOTOR CORTEX FEEDBACK ON MOUSE WHISKER SENSORY PROCESSING IN PRIMARY SOMATOSENSORY CORTEX

description: In the mouse somatosensory cortex (S1), whisker touch evokes an early and late response that travel horizontally across the cortex resembling a traveling wave. Traveling waves have been shown to be a key aspect of neural processing, and previous work has indicated the late traveling wave is reliant on long range feedback from motor cortex (MC). How these traveling waves change under a goal directed behavior and what effect MC feedback has on S1 neural processing is still unclear. To investigate the effect of MC feedback on traveling wave dynamics and neuronal spiking in S1, we inhibited MC inputs to S1 using optogenetics while recording with micro-ECoG arrays or silicon probes in S1. Under passive whisker stimulation, we observed a significant decrease in wave amplitude, wave speed, and multi-unit activity during the late period (~100ms after the deflection), accompanied with desynchronization of sensory-evoked populational response. This suggests organized and sustained S1 activity is supported by MC inputs. Interestingly, the MC-inhibition was accompanied with increased spiking in deep cortical layers, suggesting MC feedback onto S1 also has an inhibitory role. In animals performing an active whisker-based sensory discrimination task, we observed a decrease in touch evoked wave speed for reward vs non-reward whisker touches. Interestingly, inhibition of MC inputs during active touch showed an increase in spontaneous and touch evoked wave speed of both reward-associated and unassociated whiskers. This indicates MC influence on S1 traveling waves is brain state dependent. Together, our work suggests that MC feedback is critical in organizing S1 neural activity during sensory processing, potentially through regulating local excitation/inhibition balance to enable optimal neural coding.

description: The issue of beef meat supply response is an important one as it has an impact on production, nutrition, and poverty alleviation. The traditional beef meat supply that characterizes the livestock sector of Burundi may be unsustainable in providing the desired amount of food meat to the growing population and may be chocked off by a stiff competition in the regional trade agreement, COMESA and EAC where South Africa, Botswana and Kenya are the leading beef meat suppliers. This paper mainly aims to determine factors affecting beef meat supply in Bujumbura based on the structural Nerlov paradigm. Time series analysis was used on annual data for a period of 40 years (1970-2010). Both co-integration and Vector Error Correction Model (VECM) were used to fine tune the Nerlov model and determine the long-run and short-run relationships between the variables of interest. Empirical results show that the long-run relationship exists through co-integration tests and beef price supply is inelastic (ε = 0.8) as it has been expected. The speed adjustment coefficient of partial adjustment of 18% indicates that there exist some production costs that slow and retard the beef supply function to adjust to price variation. Clear mechanisms to link beef and cattle producers to market and slaughterhouses in Burundi are desirable in order to reduce or eliminate factors that constrain beef supply in Burundi.

description: We report new infrared measurements of the supermassive black hole at the Galactic Center, Sgr A*, over a decade that was previously inaccessible at these wavelengths. This enables a variability study that addresses variability timescales that are ten times longer than earlier published studies. Sgr A* was initially detected in the near-infrared with adaptive optics observations in 2002. While earlier data exists in form of speckle imaging (1995 - 2005), Sgr A* was not detected in the initial analysis. Here, we improved our speckle holography analysis techniques. This has improved the sensitivity of the resulting speckle images by up to a factor of three. Sgr A* is now detectable in the majority of epochs covering 7 years. The brightness of Sgr A* in the speckle data has an average observed K magnitude of 16.0, which corresponds to a dereddened flux density of $3.4$ mJy. Furthermore, the flat power spectral density (PSD) of Sgr A* between $\sim$80 days and 7 years shows its uncorrelation in time beyond the proposed single power-law break of $\sim$245 minutes. We report that the brightness and its variability is consistent over 22 years. This analysis is based on simulations using Witzel et al. (2018) model to characterize infrared variability from 2006 to 2016. Finally, we note that the 2001 periapse of the extended, dusty object G1 had no apparent effect on the near-infrared emission from accretion flow onto Sgr A*. The result is consistent with G1 being a self-gravitating object rather than a disrupting gas cloud.

 Forewing length: male 29.0–35.0 mm (mean (n = 5) 32.52 mm, SD = 1.751); female 31.0–35.0 mm (mean (n = 5) 33.32 mm, SD = 1.190).
 Records. This large Colotis has been recorded from Tanzania in woodlands at 300– 1800 m in the Nguu Mts, Morogoro, Turiani, the slopes of Mt Image, Udzungwa, the Ukaguru Mts, Mikumi, the Mpwapwa District and much of the western part of the country (Kielland 1990, p.59). Included here as a member of the lower slopes fauna on the basis of several specimens in BMNH collected at New Moshi in 1916 by F.C. Selous, and two males from Moshi caught at 2700 ft in June 1920 (Rothschild Collection). Larsen (1996, p.132) noted records for Taveta (see also Rogers 1913, p.99). The species ranges elsewhere south to Mozambique and northeastern South Africa, west to Namibia and Angola, and north to Somalia.
This “purple tip” has several female forms, principally reflecting white or yellow ground colour, and red or non-red forewing tip coloration. The extent of any red marking is particularly variable: in some females there are rows of more or less discrete proximal (two or three) and distal (four or five) spots within the apex, and neither, either one or the other, or both can be reddened (Kielland 1990, illustrates a white female of this last sort). As d’ Abrera (1997) noted, the forms “are connected by intergrades”.

We use this to construct semi-classical solutions of the boundary Yang-Baxter equation in the elliptic and trigonometric cases. A novel feature of the trigonometric case is that the $\mathbb{Z}_2$ action lifts to the gauge bundle in a $z$-dependent way. We construct several examples of $K$-matrices, and check they agree with cases appearing in the literature.

description: Commercialization occurs both between households within the same community, as well as between households and external markets. The drivers of commercialization at household and community level are not yet well understood. The trend in commercialization is increasing in most of the agricultural products, both in terms of the range of products involved, the number of participants and the value traded, while commercialization of wild fruit and its products still absent or extremely limited. Therefore, the main objective of this paper was to find the drivers governing the commercialization of edible wild fruits in Kenyan dry lands and to give recommendations on the possible prime movers to a commercialization of edible wild fruits among pastoralists in Kenya. An ordinal logistic regression model of binary choice was used as the major analytical tool. Therefore, this research concluded that establishing or improving the storage facility, improving transportation or road network and establishing the fruit nursery are the key factors that can motivate the community to commercialize and proper utilization this potential resource.

description: This study analyzed credit use and its effect on production efficiency of cocoa farms in Ondo State. Primary data were collected in a crosssectional survey of 183 randomly selected cocoa farms. These were drawn in a multi-stage sampling process that covered the five dominant cocoa producing Local Government Areas of Ondo State Nigeria. Data collected were analyzed using descriptive statistics and stochastic frontier. The study found that most (95.1%) of the cocoa farms were operated by males, with a mean age of 49.8years. The mean cocoa farm size was 1.28 hectares. Only 58.5% cocoa farmer’s procured credit during the 2009/2010 production season, of which (83.2%) procured credit mainly from produce merchants. The mean credit request was N238,738.30, only N113,321.50 (47.5%) were granted. Farmers that used credit had significantly (p<0.01) higher farm size (1.44Ha) and recorded significantly (p<0.01) higher net farm income (N292, 107.23/ Ha) than those that could not secure credit (1.05Ha and N183, 046.83/ Ha respectively). The empirical results revealed that cocoa farmers were operating at a point of decreasing return as depicted by the return to scale of 0.153 with mean technical efficiency of 0.44. Hire labour has positive and significant effect on output at p<0.01. Increase in credit use brings about significant reduction in technical inefficiency among the cocoa farms. The result revealed a direct relationship between access to credit and technical efficiency level. The study recommended that government and other stakeholders should support farmers to form virile farmer’s organization that will improve credit delivery through the produce merchant.

description: The productive impacts of transfer programmes have been receiving increased attention. However, little is known about such effects in emergency and crisis settings. Even less is known about whether transfer type – a food basket or a cash grant – influences the productive potential of such transfers. Theory suggests that cash transfers can relieve liquidity constraints associated with investments, but subsidised food provision, by acting as a form of insurance, may prevent households from retreating to conservative income-generating strategies during volatile periods. This report contrasts the effects of transfer modality during a randomised field experiment in Yemen. The results demonstrate a modest productive impact of both modalities and suggest a role for liquidity and price risk channels. Cash transfer recipients invested relatively more in activities with higher liquidity requirements (livestock), while food recipients incorporated higher-return crops into their agricultural portfolios.
On the micromagnetic behavior of dipolar-coupled nanomagnets in defective square artificial spin ice systems

description: We report here the results of micromagnetic simulations of square artificial spin ice (ASI) systems with defects. The defects are introduced by misaligning of a nanomagnet at the vertex. In these defective systems, we are able to stabilize emergent monopole-like state by applying a small external field. We observe a systematic change of dipolar energies of the systems with varying misalignment angle. The fields at which the emergent monopoles are created vary linearly with the dipolar energies of the systems. Our results clearly show that the magnetization reversal of the ASI systems is intricately related to the interplay of defects and dipolar interactions.

description: A correlation and probability analysis of the distribution of arrival directions for a sample of AGASA events reported to have energies above 4x10^{19} eV shows the small scale clustering to remain significant at the 99.5 - 99.9% CL and to be consistent with previous results. For the sample taken as a whole, there are no departures from either homogeneity or isotropy on angular scales greater than 5 degrees. The sample of events with E >= 6x10^{19} eV possesses no small scale clustering. Cross correlating subsamples partitioned by energy reveals three uncorrelated distributions in the intervals 4 - 5x10^{19} eV, 5 - (8-10)x10^{19} eV, and greater than (8-10)x10^{19} eV. The partition with 5 <= E < 8x10^{19} eV is correlated with the supergalactic equatorial plane while the other two groups are statistically consistent with isotropic distributions. The presence of three distinct energy-partitioned groups of events could reflect possible changes in primary composition, different source distributions, differing levels of GZK losses, or deflection effects of magnetic fields.

Subjects: subject: Instrumentation and Methods for Astrophysics (astro-ph.IM)
subject: FOS: Physical sciences

description: A new method SREAG (spherical rectangular equal-area grid) is proposed to divide a spherical surface into equal-area cells. The method is based on dividing a sphere into latitudinal rings of near-constant width with further splitting each ring into equal-area cells. It is simple in construction and use, and provides more uniform width of the latitudinal rings than other methods of equal-area pixelization of a spherical surface. The new method provides a rectangular grid cells with the latitude- and longitude-oriented boundaries, near-square cells in the equatorial rings, and the closest to uniform width of the latitudinal rings as compared with other equal-area isolatitudinal grids. The binned data is easy to visualize and interpret in terms of the longitude-latitude rectangular coordinate system, natural for astronomy and geodesy. Grids with arbitrary number of rings and, consequently, wide and theoretically unlimited range of cell size can be built by the proposed method. Comparison with other methods used in astronomical research showed the advantages of the new approach in sense of uniformity of the ring width, a wider range of grid resolution, and simplicity of use.

description: There is increasing interest in understanding if social protection can foster social cohesion, particularly between refugees and host communities. Using a cluster randomised control trial, this study examines if a short-term transfer programme targeted to Colombian refugees and poor Ecuadorians in urban and peri-urban areas of northern Ecuador led to changes in social cohesion measures. The overall results suggest that the programme contributed to reported improvements in social cohesion among Colombian refugees in the hosting community through enhanced personal agency, attitudes accepting diversity, confidence in institutions, and social participation. However, the programme had no impact on social cohesion among Ecuadorians. The programme had no negative impacts on the indicators or domains analysed. Although it was not possible to identify specific mechanisms, impacts are hypothesised to be driven by the joint targeting of Colombians and Ecuadorians, the interaction between nationalities at monthly nutrition sessions, and the messaging around social inclusion by programme implementers.

description: This study examined the socio-economic impact of the Lower Niger dredging vis-à-vis the anticipated socio-economic incentives on the fisher folks’ community in Baro, Niger state Nigeria. A simple random technique was used to select 60 fisherfolks using a well-structured questionnaire. Data obtained were analyzed using descriptive and inferential statistics. Result indicated a net increase of N2, 965.00 (USD 18.53) per month in the gross margin of the fisher folk and a marginal increase of N174.96 (USD 1.08) per after the dredging activities. This could be due to the increase in socio-economic livelihood activities brought about by enhanced accessibility of the community and more robust inland water way transportation. Conversely, it was discovered that some fish species no longer exist after dredging and 43.3% of the fisher folks spent above 10 hours per day to make a substantial catch after dredging compared with 13.3% of the same fishing time before dredging. It was however concluded that, although, the dredging project include both positive and negative impacts, the negative impacts are short-term and could be minimized if appropriate mitigation measures such as erosion and turbidity control, provision of water shed where fish nurseries would be raised, provision of adequate fishing gears and training on new fishing techniques as well as value additions to fish product are put in place.

description: In this paper, we describe all traces for the BCH star-product on the dual of a Lie algebra. First we show by an elementary argument that the BCH as well as the Kontsevich star-product are strongly closed if and only if the Lie algebra is unimodular. In a next step we show that the traces of the BCH star-product are given by the $\ad$-invariant functionals. Particular examples are the integration over coadjoint orbits. We show that for a compact Lie group and a regular orbit one can even achieve that this integration becomes a positive trace functional. In this case we explicitly describe the corresponding GNS representation. Finally we discuss how invariant deformations on a group can be used to induce deformations of spaces where the group acts on.

description: The recent trends in primary food prices have been evaluated as a signifier of the potential threats to the world in terms of food shortages and hunger. The prices of primary agricultural products like wheat and rice have risen significantly in the essential producer countries. The recent price changes were partially attributed to production shortages, which, if true, are expected to constitute a critical problem for both the suppliers and demanders. The rising prices, in accor­dance with the food shortages, are expected to influence the developing countries and the poverty lines that are mostly determined by the food intake. Accordingly, a relationship between poverty and real food prices is suspected mainly for developing and the least-developed countries. With this in mind, this study investigates the relationship between development level, including the indication of income distribution, and the producer prices of rice and wheat. We ana­lyze the degree of relationship between the Gini coefficient, indicating the level of income distribution, and various production indicators such as producer prices and yields of rice and wheat. Analysis of the data reveals that it is not possible to infer a significant relationship between yield of rice or wheat and the level of national income distribution. When the rich and poor countries are discriminated according to the level of income distribution, it is understood that rising producer prices reduce the income inequality by less than one percent. We conclude that the relationship should be reviewed with respect to contemporary changes in prices and level of income distribution and aggregates of income distribution in order to make proper inferences.

However, U.S. almond imports to India face high tariffs and non-tariff barriers which diminish the full potential of export volume for U.S. almonds. This research uses an empirical model to examine the trade effects of eliminating India's phytosanitary protocols of in-shell almond imports shipped from the U.S. for the years 2003/04 to 2006/07. The model uses a price-wedge analysis incorporating uncertainty as to the outcome of the net revenue in almond exports which adds to the economic cost of the exports. With the elimination of phytosanitary protocols, the results indicate that trade would be increased and much of the increased imports would accrue to U.S. producers. Therefore lessening restrictive import requirements for pest control will normally increase the flow of agricultural products and improve the welfare of consumers. This U.S.-India almond-trade model also can be used to estimate the trade effects of other phytosanitary measures on agricultural products.

description: This study observes the use of Facebook in the complex social phenomenon, natural disasters. By adopting an affordance perspective, this study emphasis on how local Jordanian communities harness the power of Facebook during the 2018 Dead Sea flash flood. Through using an interpretive approach, three affordances of Facebook were identified, namely, disaster warning, volunteer mobilization, and the coordination of response and recovery. Then, the researchers examined how these affordances helped the Jordanian communities to respond to disaster situations and achieve social outcomes during the floods. Based on the data analysis, it has been noticed that Facebook changed the way individuals; organizations, activists, and government respond and act to the challenges posed by a disaster. This study contributes to the emerging literature on the use of Facebook in natural disasters in the Jordanian context. There is a hope that this research could inspire more researchers about the use of emerging digital technologies in examining a variety of natural disasters.

description: Eronia leda (Boisduval, 1847)
Larsen 1996: pl. 6, figs 44 i,ii. d’ Abrera 1997: 71 (4 figs). SI: Figure 23e–h.
 Forewing length: male 25.5–30.5 mm (mean (n = 7) 27.79 mm, SD = 1.798); female 28–31.5 mm (mean (n = 6) 29.65 mm, SD = 0.878).
 Note: Nazari et al. (2011) placed this species in the resurrected monobasic genus Afrodryas Stoneham, 1957, but we have not accepted this change (see Discussion).
 Records. Found in various habitats from near sea level to 2100 m in Mpanda, Kigoma, Northern Highlands, Uluguru Mts, Mwanihana, Rubeho Mts, Pugu Hills and Masagati Forest (Kielland 1990, p.55). In the BMNH there are several specimens from Kilimanjaro, including a male from Ngare-Nairobi collected by B. Cooper at 4000–5000 ft, and a female from Old Moshi (SI: Figure 21g,h). Recorded from Taveta by Rogers (1913, p.99), and from the lower slopes of Kilimanjaro by Aurivillius (1910a, p.12). On this basis we include this species as a member of the lower slopes fauna, not having been encountered in the forest reserve area by Liseki (2009). Beyond Tanzania this butterfly has been recorded from Nigeria (northeast), Chad, Sudan (south), Ethiopia (south), Kenya, DRC (Kivu, Shaba, Haut-Lomani, Lualaba, Haut-Katanga, Tanganika), Zambia, Namibia (north), Zimbabwe, Botswana (north), Angola, Mozambique, parts of South Africa and Swaziland.
Males appear always to be bright yellow with orange tips. Females vary considerably, including male-like forms, others are almost all yellow with faint markings at the forewing apex, or with a more darkened forewing apex (f. “inargyrata”), yet others are whitish (f. “cygnophila”). Pale, whitish females never seem to have orange tips.

description: We study low-dimensional problems in topology and geometry via a study of contact and Cauchy-Riemann ($CR$) structures. A contact structure is called spherical if it admits a compatible spherical $CR$ structure. We will talk about spherical contact structures and our analytic tool, an evolution equation of $CR$ structures. We argue that solving such an equation for the standard contact 3-sphere is related to the Smale conjecture in 3-topology. Furthermore, we propose a contact analogue of Ray-Singer's analytic torsion. This ''contact torsion'' is expected to be able to distinguish among ''spherical space forms'' $\{Γ\backslash S^{3}\}$ as contact manifolds. We also propose the study of a certain kind of monopole equation associated with a contact structure. In view of the recently developed theory of contact homology algebras, we will discuss its overall impact on our study.

description: Van der Waals materials and heterostructures manifesting strongly bound room temperature exciton states exhibit emergent physical phenomena and are of a great promise for optoelectronic applications. Here, we demonstrate that nanostructured multilayer transition metal dichalcogenides by themselves provide an ideal platform for excitation and control of excitonic modes, paving the way to exciton-photonics. Hence, we show that by patterning the TMDCs into nanoresonators, strong dispersion and avoided crossing of excitons and hybrid polaritons with interaction potentials exceeding 410 meV may be controlled with great precision. We further observe that inherently strong TMDC exciton absorption resonances may be completely suppressed due to excitation of hybrid photon states and their interference. Our work paves the way to a next generation of integrated exciton optoelectronic nano-devices and applications in light generation, computing, and sensing.

description: This research finds that college students spend approximately $58 each week on total food purchases and almost $JO each week on food eaten away from home. College students allocate about 40 percent of their money spent on food eaten away from home to fast food and sit-down restaurants. College students spend roughly $18, or 32 percent of their food-purchase budget, on fruits and vegetables each week. They consume 2.35 servings of fruits each day, slightly higher than the USDA's recommendation. However, college students eat 1.87 servings of vegetables a day, which is almost a whole serving below the USDA's recommendation. This research finds that college-aged consumers are look­ing for more convenience and better prices among fruits and vegetables and may be more likely to buy more fruit and vegetable items if their needs were better met.

description: У статті здійснено комплексний аналіз принципів судового захисту прав потерпілих від воєнних злочинів у контексті сучасних викликів міжнародного гуманітарного права. Досліджено основні засади, що регулюють судовий захист, зокрема принципи гуманності, неупередженості, пропорційності та невідворотності відповідальності. Визначено, що ці принципи, сформовані на основі міжнародних конвенцій та судової практики, забезпечують фундаментальні гарантії для потерпілих, проте потребують вдосконалення у зв’язку з новими викликами, спричиненими сучасними збройними конфліктами.

Окрему увагу приділено аналізу впливу збройної агресії Російської Федерації проти України на ефективність механізмів судового захисту. Встановлено, що сучасні правові системи не завжди гарантують своєчасне та справедливе розслідування воєнних злочинів і забезпечення правосуддя для потерпілих. Запропоновано оновлену систему принципів судового захисту, яка передбачає розширення підходів до документування злочинів, посилення міжнародної співпраці та вдосконалення механізмів компенсації шкоди жертвам збройних конфліктів.

У статті наголошено на необхідності гармонізації національних правових систем із міжнародними стандартами, що сприятиме підвищенню ефективності судового переслідування винних та відновленню прав потерпілих. Акцентовано увагу на ролі міжнародних судових інституцій, зокрема Міжнародного кримінального суду (МКС) та Європейського суду з прав людини (ЄСПЛ), у забезпеченні справедливого судочинства та притягнення до відповідальності осіб, винних у воєнних злочинах.

Результати дослідження дозволяють сформувати концептуальну модель оновлених принципів судового захисту, які враховують сучасні виклики та забезпечують більш ефективний захист прав потерпілих. Запропонований підхід має практичне значення для вдосконалення судової системи України та підвищення ефективності міжнародного правосуддя.

description: Positron emission tomography (PET) imaging is an imaging modality for diagnosing a number of neurological diseases. In contrast to Magnetic Resonance Imaging (MRI), PET is costly and involves injecting a radioactive substance into the patient. Motivated by developments in modality transfer in vision, we study the generation of certain types of PET images from MRI data. We derive new flow-based generative models which we show perform well in this small sample size regime (much smaller than dataset sizes available in standard vision tasks). Our formulation, DUAL-GLOW, is based on two invertible networks and a relation network that maps the latent spaces to each other. We discuss how given the prior distribution, learning the conditional distribution of PET given the MRI image reduces to obtaining the conditional distribution between the two latent codes w.r.t. the two image types. We also extend our framework to leverage 'side' information (or attributes) when available. By controlling the PET generation through 'conditioning' on age, our model is also able to capture brain FDG-PET (hypometabolism) changes, as a function of age. We present experiments on the Alzheimers Disease Neuroimaging Initiative (ADNI) dataset with 826 subjects, and obtain good performance in PET image synthesis, qualitatively and quantitatively better than recent works.
A probe of the Radion-Higgs mixing in the Randall-Sundrum model at e^+ e^- colliders

description: In the Randall-Sundrum model, the radion-Higgs mixing is weakly suppressed by the effective electroweak scale. A novel feature of the existence of gravity-scalar mixing would be a sizable three-point vertex among the KK graviton, Higgs and radion. We study this vertex in the process e^+ e^- -> h phi, which is allowed only with a non-zero radion-Higgs mixing. It is shown that the angular distribution is a unique characteristic of the exchange of massive spin-2 gravitons, and the total cross section at the future e^+ e^- collider is big enough to cover a large portion of the parameter space where the LEP/LEP II data cannot constrain.
