description: We report neutron scattering studies on single crystals of the electron-doped (n-type) superconducting cuprate Nd2-xCexCuO4 (x=0.15) with Tc = 18 K and 25 K. Unlike the hole-doped (p-type) superconducting cuprates where incommensurate magnetic fluctuations commonly exist, the n-type cuprate shows commensurate magnetic fluctuations at the tetragonal (1/2 1/2 0) reciprocal points both in the superconducting and in the normal state. A spin gap opens up when the n-type cuprate becomes superconducting, as in the optimally doped p-type La2-xSrxCuO4. The gap energy, however, increases gradually up to about 4 meV as T decreases from Tc to 2 K, which contrasts with the spin pseudogap behavior with a T-independent gap energy in the superconducting state of p-type cuprates.

Paleorhinus

description: PALEORHINUS WILLISTON, 1904
 Type species: Paleorhinus bransoni Williston, 1904. Diagnosis: Characterized by the following autapomorphies: discrete anteroposteriorly extending row of 6–7 slightly raised nodes on the lateral surface of the jugal; low paired ridges on lateral surface of squamosal enclosing a shallow, slit-like fossa.
 Comments: Paleorhinus is a historically problematic wastebasket taxon that is in need of a full revision that is beyond the scope of the present paper. Here, we merely report characters that appear to be uniquely shared between the genotype species, Paleorhinus bransoni, and ‘ Francosuchus ’ angustifrons and thus support referral of the latter to the genus Paleorhinus (see Phylogenetic Analysis, below). An assessment of whether Paleorhinus is a subjective junior synonym of Parasuchus is beyond the scope of this work (see above).

description: In this work, novel, high-throughput metrology methods are used to perform a detailed performance loss analysis of approximately 400 industrial crystalline silicon solar cells, all coming from the same production line. The characterization sequence includes a non-destructive transfer length method (TLM) measurement technique featuring circular TLM structures hidden within the busbar region of the cells. It also includes a very fast external quantum efficiency and reflectance measurement technique. More traditional measurements, like illuminated current-voltage, Suns-VOC, and photoluminescence imaging are also used to carry out the loss analysis. The variance of the individual loss parameters and their impact on cell performance are investigated and quantified for this large group of industrial solar cells. Some important correlations between the measured loss parameters are found. The nature of these distributions and correlations provide important insights about loss mechanisms in a cell and help prioritize efforts to optimize the performance of the production line.

description: Antibody production is a key feature of the adaptive immune response. High affinity antibodies neutralise and clear invading pathogens, thereby protecting the host against microbial infections. It is now well-established that T follicular helper (Tfh) cells – a distinct subset of CD4+ T helper cells – are essential in providing cognate help to B cells in the germinal centre (GC) to differentiate into memory and long-lived plasma cells that secrete high affinity antibodies. However, stringent control of Tfh cell numbers is crucial to produce optimally affinity-matured antibody responses that are devoid of self-reactivity. Indeed, excessive number of Tfh cells has been associated with autoimmunity. However, our understanding of the molecular mechanisms controlling Tfh cell differentiation is still incomplete. This thesis focuses on characterising novel post-transcriptional mechanisms that limit Tfh cell numbers. The data presented in this thesis show that RNA-binding proteins, Roquin and its paralogue Roquin-2, cooperate to repress Icos, a key Tfh cell molecule, and limit GC reactions. Mutations in the RING or ROQ domain of Roquin disrupted Icos mRNA regulation, but, unlike the ROQ mutant that still occupied mRNA-regulating stress granules, RING-deficient Roquin failed to localise to stress granules and allowed Roquin-2 to compensate in the repression of ICOS. In addition, the data presented here show that microRNA-146a is highly expressed in human and mouse Tfh cells and its peak expression marks the decline of the Tfh cell response. Loss of miR-146a caused cell-autonomous, spontaneous accumulation of Tfh and GC B cells. Mechanistically, miR-146a acted in both Tfh and GC B cells to control ICOS-ICOSL interactions and limit Tfh and GC B cell numbers. Collectively, Roquin family proteins and miR-146a emerge as novel post-transcriptional brakes on ICOS expression, thus limiting Tfh cell numbers and GC responses.

description: This thesis provides new equilibrium existence results for markets with information asymmetries and relates them in a novel way to the role of economic intermediation. Under atomless uncertainty, single market linear price equilibria are known not to exist prevalently even when agents are risk averse expected utility maximizers. The notion of prevalence involves essentially picking an economy at random. Bypassing the nonexistence problem is one of the achievements of the nonlinear price decentralization theory. This thesis contributes by reconciling the nonlinear price decentralization theory to a large extent with certain competitive market structures. We do this in Chapter 1 by defining linear price equilibrium with multiple markets and establishing its existence. Each market has its own price vector (linear functional), and agents’ involvement in various markets is heterogeneous. As a result, price differences across markets may prevail in equilibrium. We present an example in which single market linear price equilibrium does not exist but certain corresponding equilibrium with two markets does. Our equilibrium with multiple markets has a more standard economic interpretation than equilibrium with nonlinear prices used in nonlinear decentralization theory. Our framework can potentially accommodate even more nonlinearities if economic intermediaries are explicitly introduced into the model. Despite the nonexistence problem, single market linear price equilibrium with infinitely many states is still known to exist under restrictive assumptions on the information structure. In Chapter 2, we introduce two new results on the existence of single market linear price (Radner) equilibrium with infinitely many states under economically meaningful conditions. Our first result requires that agents have independent information, while the second assumes that the total endowment of the economy is common knowledge. In Chapter 3, we explore how economic agents can test the scope of their knowledge and, in particular, the informational content of equilibrium prices under asymmetric information. We show that one can go far in arguing that equilibrium prices tend to be fully revealing.

description: Selenophorus chaparralus Purrington  (Fig. 29)
 Selenophorus chaparralus Purrington 2000: 9. Type locality: Texas (Amistad Reservoir, Val Verde Co.). Types: USNM.
 Descriptive Notes. Body size small, ABL at most 8.0 mm. Ventrite 6 of male with pair of small carinate prominences. Elytra very shiny, iridescent bluish black, contrasting with dark reddish-brown forebody. Head and pronotum proportionately small relative to elytra. Pronotum with hind angles broadly rounded, with base narrower against elytra. Elytral intervals distinctly convex, finely and irregularly micropunctulate. Median lobe has short inflation near middle, apical 1/5 bent abruptly dorsad and with a very short ostium; apical tip a knob-like process hooked in opposite directions. ABL 7.5–8.0 mm.
 Range. USA: sTX; Mexico *.
 Remarks. The males of both S. chaparralus (Fig. 29) and the Mexican species S. tubericauda share a similar bilateral pair of carinae near the apex of ventrite 6. Superficially resembling S. chaparralus and approaching the southern limit of S. chaparralus in northeastern Mexico, S. tubericauda is distinguished primarily by its dark appendages (palps, antennae, legs), dark forebody not tinged reddish, and elytra relatively dull due to distinct microsculpture mesh. The latter feature places S. tubericauda in the concinnus group. The aedeagus in one studied male from the state of Querétaro in central Mexico is normally shaped without the abrupt bend in median lobe as seen in S. chaparralus.

description: What can we learn about quantum gravity from a simple toy model, without actually quantizing it? The toy model consists of a finite number of point particles, coupled to three dimensional Einstein gravity. It has finitely many physical degrees of freedom. These are basically the relative positions of the particles in spacetime and the conjugate momenta. The resulting reduced phase space is derived from Einstein gravity as a topological field theory. The crucial point is thereby that we do not make any a priori assumptions about this phase space, except that the dynamics of the gravitational field is defined by the Einstein Hilbert action. This already leads to some interesting features of the reduced phase space, such as a non-commutative structure of spacetime when the model is quantized.

description: We conduct spectral line survey observations in the 3 mm band toward a spiral arm, a bar-end, and a nuclear region of the nearby barred spiral galaxy NGC 3627 with the IRAM 30 m telescope and the Nobeyama 45 m telescope. Additional observations are performed toward the spiral arm and the bar-end in the 2 mm band. We detect 8, 11, and 9 molecular species in the spiral arm, the bar-end, and the nuclear region, respectively. Star-formation activities are different among the three regions, and in particular, the nucleus of NGC 3627 is known as a LINER/Seyfert 2 type nucleus. In spite of these physical differences, the chemical composition shows impressive similarities among the three regions. This result means that the characteristic chemical composition associated with these regions is insensitive to the local physical conditions such as star formation rate, because such local effects are smeared out by extended quiescent molecular gas on scales of 1 kpc. Moreover, the observed chemical compositions are also found to be similar to those of molecular clouds in our Galaxy and the spiral arm of M51, whose elemental abundances are close to those in NGC 3627. Therefore, this study provides us with a standard template of the chemical composition of extended molecular clouds with the solar metalicity in nearby galaxies.

description: In this paper, we find the solutions of quartic quasitopological black holes and branes coupled to logarithmic and exponential forms of nonlinear electrodynamics. These solutions have an essential singularity at $r=0$. Depending on the value of charge parameter $q$, we have an extreme black hole/brane, a black hole/brane with two horizons or a naked singularity. For small values of parameter $q$, the solutions lead to a black hole/brane with two horizons. The values of the horizons are independent of the values of quasitopological parameters and depend only on the values of $q$, dimensions $n$, nonlinear parameter $β$ and mass parameter. Also, the solutions are not thermally stable for dS and flat spacetimes. However, AdS solutions are stable for $r_{+}>{r_{+}}_{\rm{ext}}$ which the temperature is zero for $r_{+}={r_{+}}_{\rm{ext}}$. The value of ${r_{+}}_{\rm{ext}}$ also depends on the values of parameters $q$, $β$, $n$ and $m$. As the value of ${r_{+}}_{\rm{ext}}$ decreases, the region of stability becomes larger. We also use HPEM metric to probe GTD formalism for our solutions. This metric is successful to predict the divergences of the scalar curvature exactly at the phase transition points. For large values of parameter $Ξ$, the black hole/brane has a transition to a stable state and stays stable.

description: First, the relation between black holes and limitations on information of other systems is developed. After reviewing the relation of entropy to information, we derive the entropy bound, review its applications to cosmology and its extensions to higher dimensions, and discuss why black holes behave as 1-D objects when emitting entropy. We also discuss fundamental limitations on the information of pulses in curved space, and on the rate of disposal of information into a black hole. We then move on to a discussion of quantum black holes motivated by the adiabatic invariance of horizon area of classical holes. We develop an algebraic formalism based on symmetry which gives information on the area (or mass) spectrum of quantum black holes, and on the degeneracy of the levels. This last turns out to be consistent with the horizon area-black hole entropy proportionality while leaving room for corrections.

description: Mobile context determination is an important step for many context aware services such as location-based services, enterprise policy enforcement, building or room occupancy detection for power or HVAC operation, etc. Especially in enterprise scenarios where policies (e.g., attending a confidential meeting only when the user is in "Location X") are defined based on mobile context, it is paramount to verify the accuracy of the mobile context. To this end, two stochastic models based on the theory of Hidden Markov Models (HMMs) to obtain mobile context are proposed-personalized model (HPContext) and collaborative filtering model (HCFContext). The former predicts the current context using sequential history of the user's past context observations, the latter enhances HPContext with collaborative filtering features, which enables it to predict the current context of the primary user based on the context observations of users related to the primary user, e.g., same team colleagues in company, gym friends, family members, etc. Each of the proposed models can also be used to enhance or complement the context obtained from sensors. Furthermore, since privacy is a concern in collaborative filtering, a privacy-preserving method is proposed to derive HCFContext model parameters based on the concepts of homomorphic encryption. Finally, these models are thoroughly validated on a real-life dataset.

description: Dialog acts reveal the intention behind the uttered words. Thus, their automatic recognition is important for a dialog system trying to understand its conversational partner. The study presented in this article approaches that task on the DIHANA corpus, whose three-level dialog act annotation scheme poses problems which have not been explored in recent studies. In addition to the hierarchical problem, the two lower levels pose multi-label classification problems. Furthermore, each level in the hierarchy refers to a different aspect concerning the intention of the speaker both in terms of the structure of the dialog and the task. Also, since its dialogs are in Spanish, it allows us to assess whether the state-of-the-art approaches on English data generalize to a different language. More specifically, we compare the performance of different segment representation approaches focusing on both sequences and patterns of words and assess the importance of the dialog history and the relations between the multiple levels of the hierarchy. Concerning the single-label classification problem posed by the top level, we show that the conclusions drawn on English data also hold on Spanish data. Furthermore, we show that the approaches can be adapted to multi-label scenarios. Finally, by hierarchically combining the best classifiers for each level, we achieve the best results reported for this corpus.

We resolved a double peak structure of the superconducting transition under magnetic field for the first time, which provides thermodynamic evidence for the existence of multiple superconducting phases. We also found a clear limiting of the upper critical field Hc2 for the field direction parallel to the RuO2 plane only within 2 degrees. The limiting of Hc2 occurs in the same H-T domain of the second superconducting phase; we suggest that the two phenomena have the same physical origin.

The reduced phase space can be considered as a deformed version of the phase space of two special-relativistic point particles in the centre of mass frame. When the system is quantized, we find some possibly general effects of quantum gravity, such as a minimal distances and a foaminess of the spacetime at the order of the Planck length. We also obtain a quantization of geometry, which restricts the possible asymptotic geometries of the universe.

description: The magnetic field created in proton-proton and nucleus-nucleus collisions at ultra high energies are studied with models of point-like charges and hard sphere for distribution of the constituents for vacuum conditions. The various beam ions are considered from light to heavy nuclei at energies corresponded to the nominal energies of proton beam within the projects of further accelerator facilities high-energy Large Hadron Collider (HE-LHC) and Future Circular Collider (FCC). The magnetic field strength immediately after collisions reaches the value tens of GeV$^{2}$ while the approach with point-like charges some overestimate the amplitude of the field in comparison with more realistic hard sphere model. The absolute value of magnetic field rapidly decrease with time and increases with growth of atomic number. The amplitude for $eB$ is estimated at level $100$ GeV$^{2}$ in order to magnitude for quark-quark collisions at energies corresponded to the nominal energies of proton beams. These estimations are close to the range for onset of $W$ boson condensation.

description: The formulation of the initial value problem for the Einstein equations is at the heart of obtaining interesting new solutions using numerical relativity and still very much under theoretical and applied scrutiny. We develop a specialised background geometry approach, for systems where there is non-trivial a priori knowledge about the spacetime under study. The background three-geometry and associated connection are used to express the ADM evolution equations in terms of physical non-linear deviations from that background. Expressing the equations in first order form leads naturally to a system closely linked to the Einstein-Christoffel system, introduced by Anderson and York, and sharing its hyperbolicity properties. We illustrate the drastic alteration of the source structure of the equations, and discuss why this is likely to be numerically advantageous.

description: Variability is a defining characteristic of young low-mass stars that are still accreting material from their primordial protoplanetary disk. Here we present the largest \textit{HST} variability study of Classical T Tauri stars (CTTS) to date. For 5 of these objects, we obtained a total of 25 spectra with the Space Telescope Imaging Spectrograph (STIS). Mass accretion rates and the fraction of the star covered by accretion columns (i.e., filling factors) were inferred using 1D NLTE physical models whose parameters were fit within a Bayesian framework. On week long timescales, typical changes in the mass accretion rates range up to a factor of $\sim2$, while changes of up to a factor of $\sim5$ are inferred for the filling factors. In addition to this, we observed a possible accretion burst in the transitional disk system GM Aur, and an incident we interpret as a chance alignment of an accretion column and the undisturbed photosphere along our line of sight in the full disk system VW Cha. We also measure correlations between mass accretion rate and line luminosities for use as secondary tracers of accretion. We place our objects in context with recent high-cadence photometric surveys of low-mass star formation regions and highlight the need for more broad-wavelength, contemporaneous data to better understand the physical mechanisms behind accretion variability in CTTS.

description: Epidemiology simulations have become a fundamental tool in the fight against the epidemics of various infectious diseases like AIDS and malaria. However, the complicated and stochastic nature of these simulators can mean their output is difficult to interpret, which reduces their usefulness to policymakers. In this paper, we introduce an approach that allows one to treat a large class of population-based epidemiology simulators as probabilistic generative models. This is achieved by hijacking the internal random number generator calls, through the use of a universal probabilistic programming system (PPS). In contrast to other methods, our approach can be easily retrofitted to simulators written in popular industrial programming frameworks. We demonstrate that our method can be used for interpretable introspection and inference, thus shedding light on black-box simulators. This reinstates much-needed trust between policymakers and evidence-based methods.

description: Cyberwarfare encompasses the actions by any international organization to attack and try to cause damage to another nation's infrastructure, computers or information systems through computer viruses or denial-of-service (DOS) attacks. Cyberwarfare is also known as the use or affecting in a battlespace or warfare in the background of computers, online control systems (IoTs), and networks. It comprises both aggressive and distrustful operations relating to the danger of cyberattacks, espionage, and collateral/ other damage. There are controversy and argument over whether such operations can be termed as a "war". Transnational cyber-security is an increasingly persistent issue for leading national world powers. Existing professionals are not well-resourced to deal with the continuous change in the cybersecurity field, due to an absence of detailed knowledge in the field. The United States is not only just a gigantic target for these cyber-attacks but also a leading offender. Regardless of several cyberattacks also, the nation is failed to take the appropriate measures to defend against the modern age crime - cyberwarfare.

description: Dielectric screening plays an important role in reducing the strength of carrier scattering and trapping by point defects for many semiconductors such as the halide perovskite solar materials. However, it was rarely considered as a screen to find new electronic semiconductors. We performed a material search study using the dielectric properties as a screen to identify potential electronic materials in the class of metal-pnictide ternary sulfosalts, containing Bi or Sb. These salts are basically ionic due to the electronegativity difference between the S and both the metal and pnictogen elements. However, we do find significant cross-gap hybridization between the S p-derived valence bands and pnictogen p-derived conduction bands in many of the materials. This leads to enhanced Born effective charges, and in several cases, highly enhanced dielectric constants. We find a chemical rule for high dielectric constants in terms of the bond connectivity of the pnictogen-chalcogen part of the crystal structure. We additionally find a series of compounds with low effective mass, high dielectric constant and other properties that suggest good performance as electronic materials and also several potential thermoelectric compounds. Experimental optical data and solar conversion efficiency are reported for Sn-Sb-S samples, and results in accord with predicted good performance are found. The results illustrate the utility of dielectric properties as a screen for identifying complex semiconductors.

description: Rephrasing the backbone of two-dimensional percolation as a monochromatic path crossing problem, we investigate the latter by a transfer matrix approach. Conformal invariance links the backbone dimension D_b to the highest eigenvalue of the transfer matrix T, and we obtain the result D_b=1.6431 \pm 0.0006. For a strip of width L, T is roughly of size 2^{3^L}, but we manage to reduce it to \sim L!. We find that the value of D_b is stable with respect to inclusion of additional ``blobs'' tangent to the backbone in a finite number of points.

description: The healthcare-associated infections HAIs are international health problem and its major cause of death worldwide with wide range complications among healthcare workers, patients, and visitors, And these complications are very expensive from the humanitarian and economic aspects and cause increase in healthcare resources waste as increase medications and medical supplies consumption, intensive uses of diagnostic laboratory services, sharp rising hospital's admission rates and other harmful effects on patient's life. As currently, medical laboratory specialists are the cornerstones of diagnosis of infectious diseases, the number of medical laboratories science colleges has increased, with a high number of highly qualified specialists with a strong background on microbiology and epidemiology of various disciplines that include clinical chemistry, microbiology, hematology, immunology, and histopathology. Those specialists work in laboratories of varying sizes and resources. Most of those specialists perform most tasks from different disciplines, including the microbiological tests. Therefore, the junior laboratory specialist must be fully familiar with the basic tasks and activities of infection control and prevention. The aim of this review is to know the general principles of infection control and prevention and the role of medical laboratory specialists, hoping that the medical laboratory specialists will play a valuable and effective role in the field of infection control and prevention, thereby preventing hospital infections and antibiotic resistance and providing a safe environment for the patient, health care providers and the community.
Extreme gas kinematics in an off-nuclear HII region of SDSS J143245.98+404300.3

description: We present and discuss the properties of an ionized component with extreme kinematics in an off-nuclear HII region located at 0.8 - 1.0 kpc from the nucleus of SDSS J143245.98+404300.3, recently reported in Rodriguez del Pino et al. (2019). The high-velocity gas component is identified by the detection of very broad emission wings in the Halpha line, with Full Width at Half Maximum (FWHM) > 850-1000 kms-1. Such gas kinematics are outstandingly high compared to other HII regions in local galaxies and similar to those reported in some star-forming clumps of galaxies at redshift around 2. The spatially resolved analysis indicates that the high velocity gas extends at least 90 pc and it could be compatible with an ionized outflow entraining gas at a rate 7 - 9 times larger than the rate at which gas is being converted into stars. We do not detect broad emission wings in other emission lines such as Hbeta, maybe due to moderate dust extinction, nor in [NII]6548, 6584 and [SII]6717, 6731, which could be caused by the presence of turbulent mixing layers originated by the impact of fast-flowing winds. The lack of spectral signatures associated to the presence of Wolf-Rayet stars points towards stellar winds from a large number of massive stars and/or supernovae as the likely mechanisms driving the high velocity gas.

description: Research misconduct has been a threat to Chinese biomedical research. Despite many publications dealing with research integrity in China, little empirical data is available concerning Chinese biomedical researchers’ perceptions of research integrity and misconduct. To learn more about this issue, we interviewed Chinese biomedical researchers in Europe to investigate their perceptions of this issue. Semi-structured interviews were conducted with 25 participants until data saturation was reached. The findings indicate that certain aspects of research integrity need elaboration among Chinese biomedical researchers. Participants had a vague understanding of general concepts related to research integrity. Data fabrication, data falsification and plagiarism were perceived as the most severe deviance. Inappropriate authorship (especially gift authorship) and ghost writing were regarded as the most prevalent types of research misconduct in Chinese biomedical research. The harms of certain practices, such as inappropriate authorship, salami publication and multiple submission, were not well recognized. Attitudes toward research misconduct were divided. The current scientific evaluation system, pressures of promotion, motives for fame and other factors were perceived as the main reasons for research misconduct. Participants suggested various measures in addition to existing safeguards to improve research integrity in Chinese biomedical research.
