description: The hypothalamus-pituitary-thyroid (HPT) axis regulates energy balance through the pleiotropic action of thyroid hormones. HPT basal activity and stimulation by cold or voluntary exercise are repressed by previous chronic stress in adults. Maternal separation (MS) modifies HPT basal activity we thus studied the response of the axis to energy demands and analyzed possible epigenetic changes on Trh promoter. Non-handled (NH) or MS male Wistar rats were cold exposed 1h at adulthood, only in NH rats Trh expression in the hypothalamic paraventricular nucleus (PVN) and serum TSH concentration were increased. Two weeks of voluntary exercise decreased fat mass and Trh expression, and thyroid hormones concentration changed proportionally to running distance in NH male rats and MS male rats. Although NH-females ran more than MS and much more than males, exercise decreased body weight and fat mass only in NH-rats with no change on any parameter of HPT axis, but increased Pomc expression in arcuate-nucleus of NH- whereas Npy in MS-females. Overall methylation pattern of PVN Trh gene promoter was similar in NH-males or -females; MS modified methylation of specific CpG sites, a thyroid-hormone receptor (THR) binding site present after the initiation site was hypomethylated in MS-males; in MS-females, the THR binding-site of the proximal promoter (site 4) and two sites in the first intron were hypermethylated. Our studies showed that, in a sex dimorphic manner, MS blunted the responses of HPT axis to energy demands in adult animals and caused methylation changes on Trh promoter that could alter T3 feedback.

description: We demonstrate negative refraction of microwaves in metallic photonic crystals. The spectral response of the photonic crystal, which manifests both positive and negative refraction, is in complete agreement with band-structure calculations and numerical simulations. The negative refraction observed corresponds to left-handed electromagnetism and arises due to the dispersion characteristics of waves in a periodic medium. This mechanism for negative refraction is different from that in metamaterials.

description: Inflammation of the brain is called encephalitis and may result in acute and chronic brain damage. Encephalitis can be caused by various pathogens, especially neurotropic viruses, or can occur in the context of autoimmune diseases. Encephalitis is often difficult to diagnose and to monitor precisely during the course of the disease. Thanks to highly specific detection technology, components of the neuron skeleton, such as neurofilaments, can now be reliably quantified in the peripheral blood besides cerebrospinal fluid (CSF). Among them, neurofilament light chain (NfL) has demonstrated wide utility due to high preanalytical stability, robust diagnostic technology, and excellent reproducibility. We provide an overview of how NfL has advanced diagnostics in encephalitis and outline future avenues in research needs and possible clinical applicability of NfL in adults and children.

description: A set of brackets for classical dissipative systems, subject to external random forces, are derived. The method is inspired to the old procedure found by Peierls, for deriving the canonical brackets of conservative systems, starting from an action principle. It is found that an adaptation of Peierls' method is applicable also to dissipative systems, when the friction term can be described by a linear functional of the coordinates, as is the case in the classical Langevin equation, with an arbitrary memory function. The general expression for the brackets satisfied by the coordinates, as well as by the external random forces, at different times, is determined, and it turns out that they all satisfy the Jacobi identity. Upon quantization, these classical brackets are found to coincide with the commutation rules for the quantum Langevin equation, that have been obtained in the past, by appealing to microscopic conservative quantum models for the friction mechanism.

Bounds on the Index of Rotationally Symmetric Self-Shrinking Tori

description: A closed surface evolving under mean curvature flow becomes singular in finite time. Near the singularity, the surface resembles a self-shrinker, a surface that shrinks by dilations under mean curvature flow. If the singularity is modeled on a self-shrinker other than a round sphere or cylinder, then the singularity is unstable under perturbations of the flow. One can quantify this instability using the index of the self-shrinker when viewed as a critical point of the entropy functional. In this work, we prove an upper bound on the index of rotationally symmetric self-shrinking tori in terms of their entropy and their maximum and minimum radii. While there have been a few lower bound results in the literature, we believe that this result is the first upper bound on the index of a self-shrinker. Our methods also give lower bounds on the index and the entropy, and our methods give simple formulas for two entropy-decreasing variations whose existence was proved by Liu. Surprisingly, the eigenvalue corresponding to these variations is exactly $-1$. Finally, we present some preliminary results in higher dimensions and six potential directions for future work.

description: High entropy oxides (HEOs) are a class of materials, containing equimolar portions of five or more transition metal and/or rare-earth elements. We report here about the layer-by-layer growth of HEO [(La$_{0.2}$Pr$_{0.2}$Nd$_{0.2}$Sm$_{0.2}$Eu$_{0.2}$)NiO$_3$] thin films on NdGaO$_3$ substrates by pulsed laser deposition. The combined characterizations with in-situ reflection high energy electron diffraction, atomic force microscopy, and X-ray diffraction affirm the single crystalline nature of the film with smooth surface morphology. The desired +3 oxidation of Ni has been confirmed by an element sensitive X-ray absorption spectroscopy measurement. Temperature dependent electrical transport measurements revealed a first order metal-insulator transition with the transition temperature very similar to the undoped NdNiO$_3$. Since both of these systems have a comparable tolerance factor, this work demonstrates that the electronic behaviors of $A$-site disordered perovskite-HEOs are primarily controlled by the average tolerance factor.

description: We report on a revision of our previous computation of the renormalized expectation value of the stress-energy tensor of a massless, minimally coupled scalar with a quartic self-interaction on a locally de Sitter background. This model is important because it demonstrates that quantum effects can lead to violations of the weak energy condition on cosmological scales - on average, not just in fluctuations - although the effect in this particular model is far too small to be observed. The revision consists of modifying the propagator so that dimensional regularization can be used when the dimension of the renormalized theory is not four. Although the finite part of the stress-energy tensor does not change (in D=4) from our previous result, the counterterms do. We also speculate that a certain, finite and separately conserved part of the stress tensor can be subsumed into a natural correction of the initial state from free Bunch-Davies vacuum.

description: Supersymmetry is formulated for integrable models based on the $sl(2|1)$ loop algebra endowed with a principal gradation. The symmetry transformations which have half-integer grades generate supersymmetry. The $sl(2|1)$ loop algebra leads to N=2 supersymmetric mKdV and sinh-Gordon equations. The corresponding N=1 mKdV and sinh-Gordon equations are obtained via reduction induced by twisted automorphism. Our method allows for a description of a non-local symmetry structure of supersymmetric integrable models.

description: Choosing a suitable visualization for data is a difficult task. Current data visualization recommender systems exist to aid in choosing a visualization, yet suffer from issues such as low accessibility and indecisiveness. In this study, we first define a step-by-step guide on how to build a data visualization recommender system. We then use this guide to create a model for a data visualization recommender system for non-experts that aims to resolve the issues of current solutions. The result is a question-based model that uses a decision tree and a data visualization classification hierarchy in order to recommend a visualization. Furthermore, it incorporates both task-driven and data characteristics-driven perspectives, whereas existing solutions seem to either convolute these or focus on one of the two exclusively. Based on testing against existing solutions, it is shown that the new model reaches similar results while being simpler, clearer, more versatile, extendable and transparent. The presented guide can be used as a manual for anyone building a data visualization recommender system. The resulting model can be applied in the development of new data visualization software or as part of a learning tool.

description: Eukaryotic cells transmit extracellular signal information to cellular interiors through the formation of a ternary complex made up of a ligand (or agonist), G-protein, and G-protein coupled receptor (GPCR). Previously formalized theories of ternary complex formation have mainly assumed that observable states of receptors can only take the form of monomers. Here, we propose a multiary complex model of GPCR signaling activations via the vector representation of various unobserved aggregated receptor states. Our results from model simulations imply that receptor aggregation processes can govern cooperative effects in a regime inaccessible by previous theories. In particular, we show how the affinity of ligand-receptor binding can be largely varied by various oligomer formations in the low concentration range of G-protein stimulus.

 Diagnosis
 Externally indistinguishable from C. cateianus n. sp., C. deceptus is distinguished from C. cateianus by details of the male and female genitalia. In C. deceptus, the median lobe is evenly tapered to the apex and the parameres are angulate subapically (Fig. 85); in C. cateianus, the median lobe is subparallel for most of its length and the parameres are more or less straight laterally (Fig. 84). The tubular extension of C. deceptus bears two narrow bands of spines for most of its length and appears less densely spined (Fig. 106); the tubular extension of C. cateianus has one broad band of spines (at least proximally and distally) and appears more densely spined (Fig. 105). At present, these two species are not sympatric. C. deceptus is known from central and western Nepal and northwestern India; C. cateianus is known from eastern Nepal and northeastern India.
 Description
 As in C. cateianus, except as noted.
Male genitalia, Fig. 85; parameres converging at anterior end in ventral aspect; ventral surface with long thin sclerite along midline, sclerite about 3/4 length of parameres; articulation between basal piece and parameres darkly pigmented and conspicuous. Female genitalia, Fig. 106; spermatophore present in specimen illustrated; bursa copulatrix twisted and coiled posteriorly (not shown); bursal plates attenuated at posterior angles, symmetrical; tubular extension: arising dorsally on bursa; with 2 narrow bands of spines along most of length, bands merging into broad band around base; spines about 1/2 size of bursal spines; spermatheca absent.

description: Dirac materials are of great interest as condensed matter realizations of the Dirac and Weyl equations. In particular, they serve as a starting point for the study of topological phases. This physics has been extensively studied in electronic systems such as graphene, Weyl- and Dirac semi-metals. In contrast, recent studies have highlighted several examples of Dirac-like cones in collective excitation spectra, viz. in phonon, magnon and triplon bands. These cannot be directly related to the Dirac or Weyl equations as they are bosonic in nature with pseudo-unitary band bases. In this article, we show that any Dirac-like equation can be smoothly deformed into a form that is applicable to bosonic bands. The resulting bosonic spectra bear a two-to-one relation to that of the parent Dirac system. Their dispersions inherit several interesting properties including conical band touching points and a gap-opening-role for `mass' terms. The relationship also extends to the band eigenvectors with the bosonic states carrying the same Berry connections as the parent fermionic states. The bosonic bands thus inherit topological character as well. If the parent fermionic system has non-trivial topology that leads to mid-gap surface states, the bosonic analogue also hosts surface states that lie within the corresponding band gap. The proposed bosonic Dirac structure appears in several known models. In materials, it is realized in Ba$_2$CuSi$_2$O$_6$Cl$_2$ and possibly in CoTiO$_3$ as well as in paramagnetic honeycomb ruthenates. Our results allow for a rigorous understanding of Dirac phononic and magnonic systems and enable concrete predictions, e.g., of surface states in magnonic topological insulators and Weyl semi-metals.

description: Double-black (DB) nodes have no place in red-black (RB) trees. So when DB nodes are formed, they are immediately removed. The removal of DB nodes that cause rotation and recoloring of other connected nodes poses greater challenges in the teaching and learning of RB trees. To ease this difficulty, this paper extends our previous work on the symbolic arithmetic algebraic (SA) method for removing DB nodes. The SA operations that are given as, Red + Black = Black; Black - Black = Red; Black + Black = DB; and DB - Black = Black removes DB nodes and rebalances black heights in RB trees. By extension, this paper projects three SA mathematical equations, namely, general symbolic arithmetic rule; partial symbolic arithmetic rule1; and partial symbolic arithmetic rule2. The removal of a DB node ultimately affects black heights in RB trees. To balance black heights using the SA equations, all the RB tree cases, namely, LR, RL, LL, and RR, were considered in this work; and the position of the nodes connected directly or indirectly to the DB node was also tested. In this study, to balance a RB tree, the issues considered w.r.t. the different cases of the RB tree were i) whether a DB node has an inner, outer, or both inner and outer black nephews; or ii) whether a DB node has an inner, outer or both inner and outer red nephews. The nephews r and x in this work are the children of the sibling s to a DB, and further up the tree, the parent p of a DB is their grandparent g. Thus, r and x have indirect relationships to a DB at the point of formation of the DB node. The novelty of the SA equations is in their effectiveness in the removal of DB that involves rotation of nodes as well as the recoloring of nodes along any simple path so as to balance black heights in a tree.

description: This graduate project explores how the convergence between living architecture and the concept of slowness can lead to greater social connection within the affected communities. A structured network of slow public spaces is key for cities to effectively address the complex conditions that arise within an increasingly fast culture. In order to keep up with rising density cities need to increase the capacity of these public spaces. The primary methodology is the study of typological connections at multiple scales, materiality and architectural details through scholarly research and investigative analysis.

To evaluate the issues pertaining to personal privacy and public health, we examine the usage patterns of original data, de-identification data, and encrypted data. Our specific proposal discusses the COVID index, which considers collective infection, outbreak intensity, availability of medical infrastructure, and the death rate. Finally, we summarize the findings and lessons for future research and the policy implications.

description: [Introduction] When Ukraine adopted the 2002 Land Code, it chose to follow a liberal path of agricultural land relations, but failed to create the necessary conditions for the land market to function fully. The moratorium on land sales, implemented directly after the adoption of the Land Code, prohibited 6.92 million owners of land shares (16 % of the population) from fully exercising their property rights. Initially intended as a temporary measure, the moratorium has, to date, been extended eight times. As such, many landowners have passed away without ever being able to fully exercise their property rights. Economic losses caused by the prohibition of land sales are considerable. First, inability to transfer land from less to more efficient producers contributes to a situation where tenancy insecurity substantially reduces incentives to invest in technologies improving land use productivity. As a result, growth of the agricultural sector is substantially lower than it could have been with a free land market. Second, current management of land lease contracts incurs high transaction costs, which could be lowered if land users were able to buy plots. Third, one quarter of Ukrainian agricultural land is still owned by the government. Privatization of 10.5 million ha could generate substantial financial resources for newly reformed local governments. In addition, land sales market has a potential to expand respective tax base and improve the collection of land tax. Resources from privatization and improved tax revenues could substantially help restore the dilapidated rural infrastructure. In sum, due to gains in agricultural production and land privatization, Ukrainian experts estimate that liberalization could lead to a 3-9 % increase in the annual growth rate of the GDP.

description: After two and a half decades of state-mandated cotton production, the diversification of agriculture and the downsizing of the cotton area have become prominent features of Uzbekistan's current modernization strategy. Given the momentum of agricultural policy reform, this policy brief aims to evaluate the success of farm restructuring so far. Moreover, it asks what policymakers should do next to promote agricultural competitiveness without losing sight of the social consequences of reform. After initial downsizing of the former collective farms and achieving nominal self-sufficiency in grain during the 1990s, the government has struggled to find a new model for its farming sector. In January 2019, the government initiated a new wave of farm consolidation. Rather than targeting at a particular type or size of farm organization, policymakers are recommended to focus instead on ensuring that all farmers receive undistorted market signals and have access to an optimal set of supporting public services. Stepwise liberalization of output and factor markets will contribute to this goal, and it needs to be complemented by better tailored public services to Uzbekistan's heterogeneous farming sector to lead to a successful agricultural transformation. The latter is especially important for household producers who will likely appreciate better non-farm income opportunities generated by reforms that go beyond the agricultural sector.
What about Swivel?

description: An unintended consequence of using social sciences data, especially from government sources, is that users end up devoting a significant amount of time to dealing with the mechanics of data cleanup that could (in theory) be otherwise spent thinking about the content and meaning of the data instead. Often that time is further devoted to learning a great deal about a single piece of proprietary software that may or may not continue to be available over time. Swivel appears to be a tool that resolves this problem by simplifying data visualization. It uses non-proprietary data formats as its input and automatically turns out a range of graphical displays for any table uploaded. But does this really help with the issue of misplaced effort by users? Even if it does, how might it be integrated into a data services program in an academic institution? I will be discussing my efforts to develop a more user-friendly version of the Consumer Expenditure Survey data via Swivel and where/how I think Swivel and similar tools might fit into a data services program.

description: Excavations on a large area to the east of City Walls Road, Worcester, uncovered extensive archaeological remains, which when combined with documentary and historical research has produced a wide-ranging study of the Silver Street/Lowesmoor suburb, especially from the 13th century onwards. The route of the Roman road from Droitwich was confirmed, and evidence in indicated of Anglo Saxon activity on this marshy area. Medieval developments involved tile manufacture and clay pipe making. From 1642 to the end of the Civil War the area was dominated by the bastion ditch surrounding 'St Martin's Sconce', part of the city defences. This was a major historic feature, mentioned in reports of the 1646 siege, and the site of the escape of Charles II after the Battle of Worcester in 1651. Porcelain manufacturing began here in the 19th century and five bottle ovens and parts of ancillary buildings belonging to Grainger's Porcelain Works were uncovered. Excavation produced exceptional structural and artefactual evidence for this small pottery works - which has been analysed within the historical context of 19th-century ceramic manufacture - and this can be considered as a highly significant and important investigation of this major industry.

description: Spin excitation in a nano-graphite ribbon with zigzag edges is investigated theoretically. Due to the strongly localized nature of the states near Fermi energy, the effective Hamiltonian for the low energy physics is given by Heisenberg Hamiltonian with the nearest neighbor exchange coupling. The action corresponding to the effective Hamiltonian is mapped to that of the O(3) nonlinear sigma model. It is shown that the spin excitation has a gap when the number of the zigzag lines is even, whereas the excitation becomes gapless in case of the odd number of the zigzag lines.

description: Surface roughness plays a critical role in ultrashort pulse laser ablation, particularly for industrial applications using burst mode operations, multi-pulse laser processing, and the generation of laser-induced periodic surface structures. Hence, we address the impact of surface roughness on the resulting laser ablation topography predicted by a simulation model and compared to experimental results. We present a comprehensive multi-scale simulation framework that first employs finite-difference-time-domain simulations for calculating the surface fluence distribution on a rough surface measured by an atomic-force-microscope followed by the two-temperature model coupled with hydrodynamic/solid mechanics simulation for the initial material heating. Lastly, a computational fluid dynamics model for material relaxation and fluid flow is developed and employed. Final state results of aluminum and AISI 304 stainless steel simulations demonstrated alignment with established ablation models and crater dimension prediction. Notably, Al exhibited significant optical scattering effects due to initial surface roughness of 15 nm - being 70 times below the laser wavelength, leading to localized, selective ablation processes and substantially altered crater topography compared to idealized conditions. Contrary, AISI 304 with RMS roughness of 2 nm showed no difference. Hence, we highlight the necessity of incorporating realistic, material-specific surface roughness values into large-scale ablation simulations. Furthermore, the induced local fluence variations demonstrated the inadequacy of neglecting lateral heat transport effects in this context.

description: Light emitting diodes (LEDs) in the deep ultra-violet (DUV) offer new perspectives for multiple applications ranging from 3D printing to sterilization. However, insufficient light extraction severely limits their efficiency. Nanostructured sapphire substrates in aluminum nitride based LED devices have recently shown to improve crystal growth properties, while their impact on light extraction has not been fully verified. We present a model for understanding the impact of nanostructures on the light extraction capability of DUV-LEDs. The model assumes an isotropic light source in the semiconductor layer stack and combines rigorously computed scattering matrices with a multilayer solver. We find that the optical benefit of using a nanopatterned as opposed to a planar sapphire substrate to be negligible, if parasitic absorption in the p-side of the LED is dominant. If losses in the p-side are reduced to 20%, then for a wavelength of 265 nm an increase of light extraction efficiency from 7.8% to 25.0% is possible due to nanostructuring. We introduce a concept using a diffuse ('Lambertian') reflector as p-contact, further increasing the light extraction efficiency to 34.2%. The results underline that transparent p-sides and reflective p-contacts in DUV-LEDs are indispensable for enhanced light extraction regardless of the interface texture between semiconductor and sapphire substrate. The optical design guidelines presented in this study will accelerate the development of high-efficiency DUV-LEDs, but the model is also readily applicable to other multilayer opto-electronic nanostructured devices such as photovoltaics or photodetectors.

description: As Web 2.0 continues to evolve and transform into what is being referred to as Web 3.0 we are seeing the boundaries between websites and web services blurring as more and more web content becomes remixable. Many of the resultant visualizations and applications can be achieved with no more than a basic understanding of the underlying technologies. This presentation will discuss the range of collaborative web utilities which use Web2.0 technologies which venture into the numeric and spatial data visualisation arenas. There are a whole range of map (or spatial) mash-ups which utilize Web2.0 technologies and interactive mapping products such as Google Earth and MS Virtual Earth. Such mapping utilities have paved the way for research organisations to explore and expose their findings in new and innovative ways. There has been however less publicity regarding the visualisation of data, once thought to be the remit of domain experts. This presentation will also look at and compare a number of utilities such as Swivel and Many Eyes, that to varying degrees visualise data and allow data users the opportunity to interact with and share data in an open environment.

description: Relational learning in networked data has been shown to be effective in a number of studies. Relational learners, composed of relational classifiers and collective inference methods, enable the inference of nodes in a network given the existence and strength of links to other nodes. These methods have been adapted to predict customer churn in telecommunication companies showing that incorporating them may give more accurate predictions. In this research, the performance of a variety of relational learners is compared by applying them to a number of CDR datasets originating from the telecommunication industry, with the goal to rank them as a whole and investigate the effects of relational classifiers and collective inference methods separately. Our results show that collective inference methods do not improve the performance of relational classifiers and the best performing relational classifier is the network-only link-based classifier, which builds a logistic model using link-based measures for the nodes in the network.

description: Over the decades, astronomical X-ray telescopes have utilized the Wolter type-1 optical design, which provides stigmatic imaging in axial direction but suffers from coma and higher-order aberrations for off-axis sources. The Wolter-Schwarzschild design, with stigmatic imaging in the axial direction, while suffering from higher-order aberrations, is corrected for coma, thus performing better than the Wolter type-1. The Wolter type-1 and Wolter-Schwarzschild designs are optimized for on-axis but have reduced angular resolution when averaged over a wide field of view, with the averaging weighted by the area covered in the field of view. An optical design that maximizes angular resolution at the edge of the field of view rather than at the center is more suitable for wide-field X-ray telescopes required for deep-sky astronomical surveys or solar observations. A Hyperboloid-Hyperboloid optical design can compromise axial resolution to enhance field angle resolution, hence providing improved area-weighted average angular resolution over the Wolter-Schwarzschild design, but only for fields of view exceeding a specific size. Here, we introduce a new optical design that is free from coma aberration and capable of maximizing angular resolution at any desired field angle. This design consistently outperforms Wolter-1, Wolter-Schwarzschild, and Hyperboloid-Hyperboloid designs when averaged over any field of view size. The improvement in performance remains consistent across variations in other telescope parameters such as diameter, focal length, and mirror lengths. By utilizing this new optical design, we also present a design for a full-disk imaging solar X-ray telescope.

description: Any company that aspires to industry leadership in 21st century must think in terms of global, not domestic market leadership. The world economy is globalizing at an accelerating pace as countries previously closed to foreign companies open up their markets, as the Internet shrinks the importance of geographic distance, and as ambitious growth - minded companies race to build stronger competitive positions in the markets of more and more countries. This paper focuses on strategy options for expanding beyond domestic boundaries and competing in the market of either a few or a great many countries. In the process of exploring these issues, we will introduce a number of correct concepts - multi country competition, global competition, profit sanctuaries, and cross - market subsidization. The paper includes section of market conditions; strategy options for entering and competing in foreign markets, the importance of locating operations in the most advantageous countries and so on.
