title: Screaming at the Television: How Pose Fans Interrogate Cross-Gender Relationships Between Transgender-Cisgender Couples Through Networked Counterpublics
Creators: name: Calleja, Robin
Publisher: name: Georgetown University. Communication, Culture & Technology Graduate Program
Year: 2022

description: This paper analyzes the romantic story arc between a cisgender heterosexual man (Stan) and a transgender woman (Angel) in the first season of Ryan Murphy’s groundbreaking television series, Pose (2018-2020). It also explores how fans have responded to its portrayal of a cross-gender relationship. I provide a descriptive summary of the #StanGel arc and conduct a discourse analysis within threads of the subreddit r/PoseFX on Reddit. In juxtaposition to Microsoft researcher danah boyd’s networked publics and Sarah Jackson, Moya Bailey, and Brooke Foucault Welles’ understanding of counterpublics, my discourse analysis of selected threads make three key findings: (1) new media can complement traditional media by extending the discussion beyond the screen and to a shared space; (2) LGBTQ+ fans want to see accurate portrayals of their experiences, especially its more lighthearted aspects; and (3) queer-dominated online communities like r/PoseFX serve as networked counterpublics that challenge the dominant cis-heterocentric narrative and ideologies of the mainstream society. This paper aims to contribute to both Media Studies and Queer Studies, with a greater aim of acknowledging the scarcity in academic literature on transgender representation in popular media, particularly cross-gender relationships between transgender women and cisgender men.

description: An anomalous Hall insulator without magnetic long-range ordering is theoretically reported in the absence of the relativistic spin-orbit coupling. It is realized in itinerant electrons coupled with the Ising spins on a <111> kagome plane of pyrochlore spin ice in applied magnetic field. We find that the kagome-ice type local spin correlation in the magnetization plateau state opens a charge gap without magnetic ordering, which results in quantization of the Hall conductivity. By Monte Carlo simulation, we identify the anomalous Hall insulating region in the magnetic phase diagram, in addition to another anomalous Hall insulator in a fully-saturated state.

description: Cartographic generalization is a problem, which poses interesting challenges to automation. Whereas plenty of algorithms have been developed for the different sub-problems of generalization (e.g., simplification, displacement, aggregation), there are still cases, which are not generalized adequately or in a satisfactory way. The main problem is the interplay between different operators. In those cases the human operator is the benchmark, who is able to design an aesthetic and correct representation of the physical reality. Deep learning methods have shown tremendous success for interpretation problems for which algorithmic methods have deficits. A prominent example is the classification and interpretation of images, where deep learning approaches outperform traditional computer vision methods. In both domains-computer vision and cartography-humans are able to produce good solutions. A prerequisite for the application of deep learning is the availability of many representative training examples for the situation to be learned. As this is given in cartography (there are many existing map series), the idea in this paper is to employ deep convolutional neural networks (DCNNs) for cartographic generalizations tasks, especially for the task of building generalization. Three network architectures, namely U-net, residual U-net and generative adversarial network (GAN), are evaluated both quantitatively and qualitatively in this paper. They are compared based on their performance on this task at target map scales 1:10,000, 1:15,000 and 1:25,000, respectively. The results indicate that deep learning models can successfully learn cartographic generalization operations in one single model in an implicit way. The residual U-net outperforms the others and achieved the best generalization performance.

description: Urothelial carcinoma of the bladder is a common malignancy that causes approximately 150,000 deaths per year worldwide. So far, no molecularly targeted agents have been approved for treatment of the disease. As part of The Cancer Genome Atlas project, we report here an integrated analysis of 131 urothelial carcinomas to provide a comprehensive landscape of molecular alterations. There were statistically significant recurrent mutations in 32 genes, including multiple genes involved in cell-cycle regulation, chromatin regulation, and kinase signalling pathways, as well as 9 genes not previously reported as significantly mutated in any cancer. RNA sequencing revealed four expression subtypes, two of which (papillary-like and basal/squamous-like) were also evident in microRNA sequencing and protein data. Whole-genome and RNA sequencing identified recurrent in-frame activating FGFR3–TACC3 fusions and expression or integration of several viruses (including HPV16) that are associated with gene inactivation. Our analyses identified potential therapeutic targets in 69% of the tumours, including 42% with targets in the phosphatidylinositol-3-OH kinase/AKT/mTOR pathway and 45% with targets (including ERBB2) in the RTK/MAPK pathway. Chromatin regulatory genes were more frequently mutated in urothelial carcinoma than in any other common cancer studied so far, indicating the future possibility of targeted therapy for chromatin abnormalities.

description: The possibility of charge order is theoretically examined for the Kondo lattice model in two dimensions, which does not include bare repulsive interactions. Using two complementary numerical methods, we find that charge order appears at quarter filling in an intermediate Kondo coupling region. The charge ordered ground state is an insulator exhibiting an antiferromagnetic order at charge-poor sites, while the paramagnetic charge-ordered state at finite temperatures is metallic with pseudogap behavior. We confirm that the stability of charge order is closely related with the local Kondo-singlet formation at charge-rich sites. Our results settle the controversy on charge order in the Kondo lattice model in realistic spatial dimensions.

Arches & memory: a diachronic view of Roman material culture
Creators: name: LaRocca, Austen Leigh
Publisher: name: No Publisher Supplied
Year: 2023

description: This project examines the form of the freestanding Roman arch in its historical, cultural, and ideological contexts from its inception to the present. Paying particular attention to those arches within the city of Rome itself, this paper traces the history of freestanding arches erected in the capital from the time of their construction to the time of their (in most cases) destruction and disappearance. By looking at the lives of these arches beyond the ancient period this dissertation will show that monuments act as palimpsests, accumulating meaning with each successive historical generation. In particular, arches have evolved to become a universal symbol of Imperial Triumph, an identity which is both removed from their complex ancient uses, and problematic in the 21st century. This research uses archaeological records, primary sources, written and visual representations, historiographical accounts, and comparative examples to demonstrate the layers of identity on Roman arches and the manner in which these monumental palimpsests accumulated, and manifested over the course of two millennia. By looking at Roman arches, a relatively ubiquitous and recognizable form, this study will demonstrate the complexities and contradictions inherent in even the most familiar and ancient monuments.

description: The unsteady flows over a shallow rectangular cavity at Mach 1·5 and 2·5 are modified at the leading edge by using compression ramps, expansion surfaces, and mass injection. The study is performed through solutions of Short-time Reynolds-Averaged Navier–Stokes equations (TRANS) with turbulence modelled by a two-equation k–v model. When a compression ramp is introduced, two types of responses are observed: at Mach 1·5, a strong flapping motion leads to small changes in the frequency and sound pressure level in the cavity compared with the baseline case of rectangular geometry. The roll-up of the shear layer produces convective vortices, leading to enhanced pressure fluctuations on the downstream surface; At Mach 2·5, a weak shear layer instability produces a reduction in the sound pressure level, and the increased distance between the leading edge and the trailing edge produces a reduction in frequency. An increase in the mean pressure drag coefficient is produced due to the high pressure on the ramp. When an expansion surface is employed, the mean pressure drag coefficient is also increased slightly. When the flow is attached to the surface, the major flow physics are similar to the baseline case. A reduction of the sound pressure level is observed in the cavity with the surface height. When a shock induced separation occurs on the surface, a steady flow is established in the cavity. When the mass injection is introduced, a passive pressure response is observed at the leading edge, producing local vorticity and vortex shedding. The flow mechanism remains the same at both Mach numbers, with a weak sitting vortex near the rear corner. An optimal mass injection pressure ratio is identified.
A co-rotational based anisotropic elasto-plastic model for geometrically non-linear analysis of fibre reinforced polymer composites: Formulation and finite element implementation

description: Geometrical non-linearity is one of the aspects to be taken into account for accurate analysis of fibre reinforced polymers (FRPs), since large displacements and rotations may be observed in many of its structural applications such as in aircraft wings and wind turbine blades. In this paper, a co-rotational formulation and implementation of an invariant-based anisotropic plasticity model are presented for geometrically non-linear analysis of FRPs. The anisotropic constitutive equations are formulated in the format of isotropic tensors functions. The model assumes an anisotropic pressure-dependent yield function, and in addition to this, a non-associated plastic potential function in order to model realistic plastic deformations in FRPs. The formulation is then cast in the co-rotational framework to consider the geometrical non-linear effects in an efficient manner. The developed model is implemented in the commercial finite element (FE) software ABAQUS/Implicit via the means of the user-defined material subroutine (UMAT). The kinematics within the co-rotational frame is explained briefly while the important aspects regarding the numerical treatment and implementation are discussed in detail. Representative numerical examples at different scales are presented to demonstrate the applicability and robustness of the proposed development.

description: Recent progress in nanotechnology has allowed to fabricate new hybrid systems where a single two-level system is coupled to a mechanical nanoresonator. In such systems the quantum nature of a macroscopic degree of freedom can be revealed and manipulated. This opens up appealing perspectives for quantum information technologies, and for the exploration of quantum-classical boundary. Here we present the experimental realization of a monolithic solid-state hybrid system governed by material strain: a quantum dot is embedded within a nanowire featuring discrete mechanical resonances corresponding to flexural vibration modes. Mechanical vibrations result in a time-varying strain field that modulates the quantum dot transition energy. This approach simultaneously offers a large light extraction efficiency and a large exciton-phonon coupling strength $g_0$. By means of optical and mechanical spectroscopy, we find that $g_0/2π$ is nearly as large as the mechanical frequency, a criterion which defines the ultra-strong coupling regime.

Photoinduced Electron Transfer in Donor-Acceptor Systems for MALDI: a DFT Study
Creators: name: Campo Hernandez, Emmanuel

Publisher: name: Zenodo
Year: 2023

description: Phytoplankton chemotaxonomy is a valuable tool for classifying organisms based on molecular patterns. In particular, the enormous complexity and diversity of identifying these organisms has led to a wide discussion on phytoplankton chemotaxonomy [1]. Phytoplankton have a unique combination and distribution of pigments in their photosystems PSI and PSII, such as chlorophylls and carotenoids, which act as biomarkers, allowing for their identification and taxonomic classification. Matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) can be used to perform phytoplankton chemotaxonomy by analyzing these biosignature pigments and their patterns [2]. MALDI is based on analyte ionization and uses an organic compound, known as a matrix, to regulate this ionization process. The selection of the MALDI matrix depends on the analyte and the aim of the analysis [3]. Currently, our research groups, GIFTEX-UIS and IN SILICO-UNISUCRE, are using 2,5-dicyano-1,4-benzoquinone (DCTB) and α-cyano-4-hydroxycinnamic acid (CHCA) electron transfer (ET) matrices to efficiently analyze the pigments mentioned above [4]. Additionally, we have synthesized Donor-Acceptor (D-A) systems from Triphenylamine (TFA), which are substituted with -CN, -COOCH3, and -COOH, to enhance MALDI analysis. The D-A compounds have shown a good response in laser desorption/ionization (LDI) assays [5]. These D-A compounds are based on charge delocalization, which acts in MS positive and negative modes. However, the photochemical and dynamic quantum features of these structures and ET processes involved are not fully understood. Therefore, to optimize the use of D-A as MALDI ET matrices, it is necessary to understand the photoexcitation and ET processes at the quantum level. For this reason, we conducted a theoretical photophysical characterization and analysis using Density Functional Theory (DFT) using INKARI (UNSA, Perú) and GUANE (UIS, Colombia) supercomputers, focusing our efforts on the characterization of the structure and multiple optoelectronic properties that include the characterization of the molecular orbitals HOMO, LUMO, UV-vis, IRs, charge distribution analysis, and molecular electrostatic potential (MEP) maps. Through this project, we aim to gain a deep understanding of these systems in relation to their structure-photoreactivity at the mechano-quantum level, thereby providing a more solid basis for the reliable use of these D-A systems as matrices for ET analysis, which is an area of great analytical chemical interest.

description: An investigation on the feasibility of utilizing Mode Division Multiplexing (MDM) for simultaneous measurement of Surrounding Refractive Index (SRI) and temperature using a single sensor element based on an etched OM4 Graded Index Multi Mode Fiber (GI-MMF) with an integrated fiber Bragg Grating (BG), is presented. The proposed work is focused on the concept of principle mode groups (PMGs) generated by the OM4 GI-MMF whose response to SRI and temperature would be different and thus discrimination of the said two parameters can be achieved simultaneously via a single sensor element. Results indicate that the response of all PMGs to temperature to be equal, i.e., 11.4 pm/°C, while the response to SRI depends on each PMG. Thus, it is evident that temperature "de-coupled" SRI measurement can be achieved by deducing the temperature effects experienced by the sensor element. Sensitivity of the PMGs to applied SRI varied from 3.04 nm/RIU to of 0.22 nm/RIU from the highest to lowest PMG, respectively. The results verify that it is feasible to obtain dual measurement of SRI and temperature simultaneously using the same, i.e., single, sensing element. © 2020 by authors.

description: The purpose of this study is to propose the Bayesian network (BN) model to estimate flood peaks from atmospheric ensemble forecasts (AEFs). The Weather Research and Forecasting (WRF) model was used to simulate historic storms using five cumulus parameterization schemes. The BN model was trained to compute flood peak forecasts from AEFs and hydrological pre-conditions. The mean absolute relative error was calculated as 0.076 for validation data. An artificial neural network (ANN) was applied for the same problem but showed inferior performance with a mean absolute relative error of 0.39. It seems that BN is less sensitive to small data sets, thus it is more suited for flood peak forecasting than ANN.
North Carolina's Stream Watch Program: Citizen Involvement in Water Protection

Year: 1983

description: North Carolina's Department of Natural Resources and Community Development (NRCD), under the leadership of Secretary Joe Grimsley, has placed a high priority on increasing citizen involvement in the department's programs. The Stream Watch program, launched in March 1983, was developed to encourage citizens to become actively involved in local water resource management and protection. The program's three primary goals are: The seven NRCD regional offices provide staff support for Stream Watch activities, but groups must take the initiative for planning appropriate projects. Financial support has been made available through a $30,000 grant from the Z. Smith Reynolds Foundation. This money has been allocated to many groups throughout the state in the form of grants ranging from $200 to $1000. 1. To encourage North Carolina's citizens to "adopt" watersheds near their homes and make a long-range commitment to watch over and care for those areas 2. To increase citizens' awareness of and involvement in water resource management and protection 3. To establish a working partnership among North Carolina's citizens, industries and state and local governments. Citizen groups interested in participating in Stream Watch are asked to identify a local creek, river, lake or estuary that they are particularly concerned about. They agree to adopt that area, and register it with the central Stream Watch Coordinator in Raleigh. In return, they receive a folder of information on the Stream Watch program and related water resource issues. The groups are asked to inventory their adopted areas, learning about their history, land uses and natural assets. They should evaluate the areas' potentials and take stock of their present needs and problems.

description: During the assessment of the electromagnetic emissions of wind turbines (WTs), the aspects of measurement uncertainty must be taken into account. Therefore, this work focuses on the measurement uncertainty which arises through distance errors of the measuring positions around a WT. The measurement distance given by the corresponding standard is 30 m with respect to the WT tower. However, this determined distance will always differ e.g. due to unevenness of the surrounding ground, leading to measurement uncertainties. These uncertainties can be estimated with the knowledge of the electromagnetic field distribution. It is assumed in standard measurements, that the electromagnetic field present is a pure transversal electromagnetic field (far field). Simulations of a simplified WT model with a hub height of 100 m shows that this assumption is not effective for the whole frequency range from 150 kHz to 1 GHz. For frequencies below 3 MHz the field distribution is monotonically decreasing with the distance from the WT since it behaves like an electrical small radiator. Whereas for frequencies above 3 MHz, where the investigated model forms an electrical large radiator, the field distribution becomes more complex and the measurement uncertainty of the field strength at the observation point increases. Therefore, this work focuses on investigations where the near field becomes a far field. Based on the simulation results, a method for minimizing the uncertainty contribution caused by distance errors is presented. Therefore, advanced measurement uncertainty during in situ test of WTs can be reduced.

description: We investigate experimentally an exotic state of electronic matter obtained by fine-tuning to a quantum critical point (QCP), realized in a spin-polarized resonant level coupled to strongly dissipative electrodes. Several transport scaling laws near and far from equilibrium are measured, and then accounted for theoretically. Our analysis reveals a splitting of the resonant level into two quasi-independent Majorana modes, one strongly hybridized to the leads, and the other tightly bound to the quantum dot. Residual interactions involving these Majorana fermions result in the observation of a striking quasi-linear non-Fermi liquid scattering rate at the QCP. Our devices constitute a viable alternative to topological superconductors as a platform for studying strong correlation effects within Majorana physics.

description: Abstract Background Deaths and injuries arising from interpersonal violence among adolescents are major public health concerns in the United States. The bearing of weapons among adolescents is a critical factor in many of these deaths and injuries. Methods A secondary analysis of the 2005 United States Youth Risk Behavior Surveillance System Survey data was carried out to examine the variables associated with self-reported history of weapon carrying on school property among high school students. We used logistic regression analysis to assess the associations. Results Of the 13,707 respondents who participated in the survey, 10.2% of males and 2.6% of females reported carrying a weapon on school property. In multivariate logistic regression analysis, males were more likely to report having carried a weapon than females (odds ratio (OR) = 5.58; 95% confidence interval (CI) [4.23, 7.62]). Self-reported race/ethnicity was also associated with weapon carrying. Other variables positively associated with weapon carrying at school were substance use (OR = 1.77; 95% CI [1.16, 2.68]), depression (OR = 1.44; 95% CI [1.10, 1.89]), suicidal ideation (OR = 1.64; 95% CI [1.23, 2.19]), having had property stolen or deliberately damaged at school (OR = 1.55; 95% CI [1.21, 1.98]), having been raped (OR = 1.70; 95% CI [1.22, 2.37]), having been threatened or injured with a weapon on school property (OR = 2.19; 95% CI [1.63, 2.95]), and having engaged in physical fighting (OR = 2.02; 95% CI [1.56, 2.63]). Conclusion This research identifies factors that are associated with weapon bearing among adolescents in the United States. These factors may be important in the design of interventions aimed at improving school safety and adolescent health.
Ferromagnetism and the formation of interlayer As2-dimers in Ca(Fe1-xNix)2As2

description: The compounds Ca(Fe1-xNix)2As2 with the tetragonal ThCr2Si2-type structure (space group I4/mmm) show a continuous transition of the interlayer As-As distances from a non-bonding state in CaFe2As2 (dAs-As = 313 pm) to single-bonded As2-dimers in CaNi2As2 (dAs-As = 260 pm). Magnetic measurements reveal weak ferromagnetism which develops near the composition Ca(Fe0.5Ni0.5)2As2, while the compounds with lower and higher nickel concentrations both are Pauli-paramagnetic. DFT band structure calculations reveal that the As2-dimer formation is a consequence of weaker metal-metal in MAs4-layers (M = Fe1-xNix) of Ni-richer compounds, and depends not on depopulation or shift of As-As antibonding states as suggested earlier. Our results also indicate that the ferromagnetism of Ca(Fe0.5Ni0.5)2As2 and related compounds like SrCo2(Ge0.5P0.5)2 is probably not induced by dimer breaking as recently suggested, but arises from the high density of states generated by the transition metal 3d bands near the Fermi level without contribution of the dimers.

description: For generations, America's brightest students have followed a College Prep course of study during their high school years. While this group of students has been guided through their high school experience, the majority of students have been left to their own devices to select the courses in which they will enroll. Being human beings and prone to human weaknesses, these students have usually chosen the path of least resistance and taken the least demanding courses possible. Few students take Algebra by choice! Often, the only goal for the majority of students has been to finish. Unfortunately, as our nation's high drop-out statistics indicate, finishing school has not always included receiving a diploma. There is a certain irony in this scenario. Not trusting the intellect of our more advanced students to make the correct choices, we, as educators, have designed their curricula. Conversely, we have entrusted our average and below-average students with the decisions regarding the selection of their high school coursework, decisions that will affect their lives ever after.

description: DNA microarrays are a relatively new technology that can simultaneously measure the expression level of thousands of genes. They have become an important tool for a wide variety of biological experiments. One of the most common goals of DNA microarray experiments is to identify genes associated with biological processes of interest. Conventional statistical tests often produce poor results when applied to microarray data due to small sample sizes, noisy data, and correlation among the expression levels of the genes. Thus, novel statistical methods are needed to identify significant genes in DNA microarray experiments. This article discusses the challenges inherent in DNA microarray analysis and describes a series of statistical techniques that can be used to overcome these challenges. The problem of multiple hypothesis testing and its relation to microarray studies is also considered, along with several possible solutions.

The Winston-Salem Transit Authority: Planning for Mobility Management
Creators: name: Nalevanko, Anna M.
Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 1995

description: With the passage of the Intermodal Surface Transportation Act (ISTEA) of 1991, the national transportation focus has shifted to a more integrated approach of developing transportation systems. Transit services, infrastructure, and community designs that support transit, such as parking policies, bicycle paths, and transit-oriented development are all considered part of a balanced, efficient transportation system. With greater emphasis on transit and non-automobile modes of transportation, transportation professionals are challenged to explore more cost-effective, efficient approaches to deliver transit service, and to pursue better integration of the various public transportation modes (i.e., rail, intercity bus). Public transit can be a viable alternative to the single occupancy vehicle if the service is accessible and designed to meet the needs of the community. In many cases, enhancements can be achieved through the implementation of advanced, transit-specific technologies. This article outlines how a multi-disciplinary team has come together to enhance service delivery in one North Carolina community. The Winston-Salem Transit Authority (WSTA) is investigating service delivery improvements through the implementation of advanced communication and information technologies. What is learned from the application of transit-specific technologies at WSTA will benefit transit operations in the state and nationally.

description: Epsilon-near-zero-materials (ENZ-materials) and their unique properties are key to the successful integration and miniaturization of optical components. Novel concepts, which promise significant progress in this field of research, such as optical switches and thin film electrooptical modulators, are possible when the electrical and optical properties of ENZ-materials are carefully exploited. To achieve a greater understanding of these properties, in this paper the electrical conductivity, optical transmittance, as well as absorption of thin indium tin oxide films, are investigated and linked to their laser-induced damage threshold in the ultra-short pulse regime. To the best of the authors’ knowledge, this is the first concise study linking the electrical properties of indium tin oxide to its properties regarding high-power laser applications. © 2020.

Quasi-representations of surface groups

description: By a quasi-representation of a group $G$ we mean an approximately multiplicative map of $G$ to the unitary group of a unital $C^*$-algebra. A quasi-representation induces a partially defined map at the level $K$-theory. In the early 90s Exel and Loring associated two invariants to almost-commuting pairs of unitary matrices $u$ and $v$: one a $K$-theoretic invariant, which may be regarded as the image of the Bott element in $K_0(C(\mathbb{T}^2))$ under a map induced by quasi-representation of $\mathbb{Z}^2$ in U(n); the other is the winding number in $\mathbb{C}\setminus \{0\}$ of the closed path $t\mapsto \det(tvu + (1-t)uv)$. The so-called Exel-Loring formula states that these two invariants coincide if $\|uv - vu\|$ is sufficiently small. A generalization of the Exel-Loring formula for quasi-representations of a surface group taking values in U(n) was given by the second-named author. Here we further extend this formula for quasi-representations of a surface group taking values in the unitary group of a tracial unital $C^*$-algebra.

description: When performing joint actions, people rely on common ground - shared information that provides the required basis for mutual understanding. Common ground can be based on people's interaction history or on knowledge and expectations people share, e.g., because they belong to the same culture or social class. Here, we suggest that people rely on yet another form of common ground, one that originates in their similarities in multisensory processing. Specifically, we focus on 'crossmodal correspondences' - nonarbitrary associations that people make between stimulus features in different sensory modalities, e.g., between stimuli in the auditory and the visual modality such as high-pitched sounds and small objects. Going beyond previous research that focused on investigating crossmodal correspondences in individuals, we propose that people can use these correspondences for communicating and coordinating with others. Initial support for our proposal comes from a communication game played in a public space (an art gallery) by pairs of visitors. We observed that pairs created nonverbal communication systems by spontaneously relying on 'crossmodal common ground'. Based on these results, we conclude that crossmodal correspondences not only occur within individuals but that they can also be actively used in joint action to facilitate the coordination between individuals.

Multi Higgs and Vector boson production beyond the Standard Model

description: If the electroweak symmetry breaking is originated from a strongly coupled sector, as for instance in composite Higgs models, the Higgs boson couplings can deviate from their Standard Model values. In such cases, at sufficiently high energies there could occur an onset of multiple Higgs boson and longitudinally polarised electroweak gauge boson (V_L) production. We study the sensitivity to anomalous Higgs couplings in inelastic processes with 3 and 4 particles (either Higgs bosons or V_L's) in the final state. We show that, due to the more severe cancellations in the corresponding amplitudes as compared to the usual 2 to 2 processes, large enhancements with respect to the Standard Model can arise even for small modifications of the Higgs couplings. In particular, we find that triple Higgs production provides the best multiparticle channel to look for these deviations. We briefly explore the consequences of multiparticle production at the LHC.

description: Despite great efforts, transoral robotic laser surgery has not been established clinically. Patient benefits are yet to be proven to accept shortcomings of robotic systems. In particular, laryngeal reachability and transition from microscope to accurate endoscopic laser ablation have not been achieved. We have addressed those challenges with a highly integrated robotic endoscope for non-contact endolaryngeal laser surgery. The current performance status has been assessed in multi-level user studies. In addition, the system was deployed to an ex vivo porcine larynx. The robotic design comprises an extensible continuum manipulator with multifunctional tip. The latter features laser optics, stereo vision, and illumination. Vision-based performance assessment is derived from depth estimation and scene tracking. Novices and experts (n = 20) conducted teleoperated delineation tasks to mimic laser ablation of delicate anatomy. Delineation with motion-compensated and raw endoscopic visualisation was carried out on planar and non-planar nominal patterns. Root mean square tracing errors of less than 0.75 mm were feasible with task completion times below 45 s. Relevant anatomy in the porcine larynx was exposed successfully. Accuracy and usability of the integrated platform bear potential for dexterous laser manipulation in clinical settings. Cadaver and in vivo animal studies may translate ex vivo findings. © 2020, The Author(s).
