description: We present predictions for top anti-top bottom anti-bottom production at the LHC in next-to-leading order QCD. The precise description of this background process is a prerequisite to observe associated top anti-top Higgs production in the Higgs -> bottom anti-bottom decay channel and to directly measure the top-quark Yukawa coupling at the LHC. The leading-order cross section is extremely sensitive to scale variations. We observe that the traditional scale choice adopted in ATLAS simulations underestimates the top anti-top bottom anti-bottom background by a factor two and introduce a new dynamical scale that stabilizes the perturbative predictions. We study various kinematic distributions and observe that the corrections have little impact on their shapes if standard cuts are applied. In the regime of highly boosted Higgs bosons, which offers better perspectives to observe the top anti-top Higgs signal, we find significant distortions of the kinematic distributions. The one-loop amplitudes are computed using process-independent algebraic manipulations of Feynman diagrams and numerical tensor reduction. We find that this approach provides very high numerical stability and CPU efficiency.

description: We study classes of dynamical systems that can be obtained by constructing recursive networks with monotone Boolean functions. Stack filters in nonlinear signal processing are special cases of such systems. We show an analytical connection between coefficients used to optimize the statistical properties of stack filters and their sensitivity, a measure that can be used to characterize the dynamical properties of Boolean networks constructed from the corresponding monotone functions. A connection is made between the rank selection probabilities (RSPs) and the sensitivity. We also examine the dynamical behavior of monotone functions corresponding to filters that are optimal in terms of their noise suppression capability, and find that the optimal filters are dynamically chaotic. This contrasts with the optimal information preservation properties of critical networks in the case of small perturbations in Boolean networks, and highlights the difference between such perturbations and those corresponding to noise. We also consider a generalization of Boolean networks that is obtained by utilizing stack filters on continuous-valued states. It can be seen that for such networks, the dynamical regime can be changed when binary variables are made continuous.

Year: 2025

description: Thyroid eye disease (TED) significantly affects patients' quality of life (QoL), leading to substantial physical, emotional, and social impairments. Teprotumumab, a fully human monoclonal antibody targeting the insulin-like growth factor-1 receptor, has emerged as a novel treatment option for moderate to severe TED. This review explores the mechanism and efficacy of Teprotumumab, its impact on patients' QoL, and the importance of integrating QoL assessments into clinical practice. Current evidence highlights that Teprotumumab not only alleviates ocular symptoms but also enhances overall well-being, emphasizing the need for holistic management strategies in TED.

description: We present new 7 mm and archive 1.3 cm high angular resolution observations of the HL/XZ Tau region made with the VLA. At 7 mm, the emission from HL Tau seems to be arising in a clumpy disk with radius of order 25 AU. The 1.3 cm emission from XZ Tau shows the emission from a binary system with 0"3 (42 AU) separation, known from previous optical/IR observations. However, at 7 mm, the southern radio component resolves into a binary with 0"09 (13 AU) separation, suggesting that XZ Tau is actually a triple star system. We suggest that the remarkable ejection of gas from the XZ Tau system observed with the HST may be related to a periastron passage of this newly discovered close binary system.

description: In the framework of supersymmetric Grand Unified Theories, the minimal Higgs sector is often extended by introducing multi-dimensional Higgs representations in order to obtain realistic models. However these constructions should remain anomaly-free, which constraints significantly their structure. We review the necessary conditions for the cancellation of anomalies in general and discuss in detail the different possibilities for SUSY SU(5) models. Alternative anomaly free combinations of Higgs representations, beyond the usual vector-like choice, are identified, and it is shown that their corresponding beta functions are not equivalent. Although the unification of gauge couplings is not affected, the introduction of multi-dimensional representations leads to different scenarios for the perturbative validity of the theory up to the Planck scale.

description: Background: With increasing survival following the use of antiretroviral therapy, adolescents living with Human Immunodeficiency Virus (ALHIV) could have complications such as delayed puberty and psychological complications. In Nigeria, there is limited data on the association between delayed sexual maturation and psychosocial dysfunction in ALHIV. The objective of this study was to determine the prevalence and the association between delayed sexual development (DSD) and psychosocial dysfunction (PSD) in ALHIV and compare it with uninfected adolescents.

Methodology: This was a cross-sectional study carried out at the Lagos University Teaching Hospital (LUTH), Nigeria and it involved 144 ALHIV and an equal number of HIV-negative controls who were matched for age, sex and social class. Information was obtained from participants using interviewer-administered questionnaires; their stages of sexual development and their psychosocial function were assessed using Tanner staging criteria and the Paediatric Symptom Checklist tool respectively. Data were analysed using the Statistical Package for Social Sciences software version 23.

Results: The mean (±SD) age of ALHIV and the HIV-negative controls was 14.8 (±3.0) and 14.8 (±2.9) years respectively. All the ALHIV were on HAART and 99.3% were in clinical stage 1. There was no significant difference between the prevalence of DSD among the ALHIV (9.4%) and the HIV-negative controls (6.4%) (p= 0.402). The prevalence of PSD in ALHIV and HIV-negative controls were 4.9% and 5.6% respectively (p=0.791). There was no significant association between PSD and DSD in both groups of study participants (p=0.459 and p=0.301).

Conclusion: The prevalence of PSD and DSD were low and similar among adolescents with and without HIV, and no association was found between PSD and DSD. However, routine screening of adolescents for PSD should be practised for early identification and prompt management where indicated.

description: We present the derivation and code implementation of a first-principles methodology to calculate the lattice-mediated contributions to the bulk flexoelectric tensor. The approach is based on our recent analytical long-wavelength extension of density-functional perturbation theory [Royo and Stengel, Phys. Rev. X 9, 021050 (2019)], and avoids the cumbersome numerical derivatives with respect to the wave vector that were adopted in previous implementations. To substantiate our results, we revisit and numerically validate the sum rules that relate flexoelectricity and uniform elasticity by generalizing them to regimes where finite forces and stresses are present. We also revisit the definition of the elastic tensor under stress, especially in regards to the existing linear-response implementation. We demonstrate the performance of our method by applying it to representative cubic crystals and to the tetragonal low-temperature polymorph of SrTiO$_3$, obtaining excellent agreement with the available literature data.

description: Background: Air pollution from vehicular emissions and other sources accounts for over seven million global deaths annually and contributes significantly to environmental degradation, including climate change. Vehicular emission is not prioritized for control in Nigeria, thus undermining public health and the Sustainable Development Goals 3, 11 and 13. This study aims to characterize vehicular emissions in Abuja municipality and quantify exhaust air pollutants of commonly used vehicles.

Methodology: Cross-sectional exhaust emissions study of vehicles in Abuja Municipal Area Council. Information on the type and age, fuel type, purchase and use category of 543 vehicles on routine Annual Road Worthiness Test at the Computerized Test Center, Abuja. Exhaust levels of CO, CO2 HCHO and PM10 were measured using hand-held devices. IBM SPSS version 26.0.0.0 (2019) statistical software.

 Results: The Toyota brand comprised 52.5% of the vehicles. Over 80% were older than 10 years; 85.5% were preowned and 87.3% were used for private purposes. PMS was the dominant fuel used (91.1%). Except for PM10, older vehicles emitted higher levels of the measured pollutants than newer ones. The differences were significant for CO and HCHO. Diesel-fueled and commercial vehicles also emitted higher levels of CO, HCHO and PM10 compared to PMS-fueled and private vehicles respectively.

Conclusions: Strong regulatory policies that discourage over-aged vehicles; speedy adoption of the ECOWAS guidelines on cleaner fuels and emission limits; and coordinated implementation of effective Inspection & Monitoring programmes by relevant government agencies are required to safeguard public health and the environment. We also recommend the introduction of vehicles powered by alternative energy, the use of bicycles, designation of one-way traffic and pedestrian zones.

description: Using molecular-dynamics simulation, we study the crater volumes induced by energetic impacts ($v= 1- 250$ km/s) of projectiles containing up to N=1000 atoms. We find that for Lennard-Jones bonded material the crater volume depends solely on the total impact energy $E$. Above a threshold $\Eth$, the volume rises linearly with $E$. Similar results are obtained for metallic materials. By scaling the impact energy $E$ to the target cohesive energy $U$, the crater volumes become independent of the target material. To a first approximation, the crater volume increases in proportion with the available scaled energy, $V=aE/U$. The proportionality factor $a$ is termed the cratering efficiency and assumes values of around 0.5.

description: We discuss some details for the model proposed in Ref. \cite{aks-prl}, in which neutrino oscillation, dark matter, and baryon asymmetry of the Universe can be simultaneously explained by the TeV-scale physics without introducing very high mass scales. An exact discrete $Z_2$ symmetry is introduced, under which new particle contents (a real singlet scalar field, a pair of charged singlet scalar fields and TeV-scale right-handed neutrinos) are assigned to have odd quantum number, whereas ordinary gauge fields, quarks and leptons, and two Higgs doublets are even. Tiny neutrino masses are generated at the three loop level due to the exact $Z_2$ symmetry, by which stability of the dark matter candidate is also guaranteed. The extra Higgs doublet is required not only for the tiny neutrino masses but also for successful electroweak baryogenesis. We discuss phenomenological properties of the model, and find that there are successful scenarios in which above three problems are solved simultaneously under the constraint from current experimental data. We then discuss predictions in such scenarios at ongoing and future experiments. It turns out that the model provides discriminative predictions especially in Higgs physics and dark matter physics, so that it is testable in near future.

description: Background: To determine the level of knowledge and challenges associated with learning movement disorders among final-year medical students. Methodology: A cross-sectional survey of 79 final-year medical students at the Madonna University, Elele, Rivers State. Consenting students filled out the study questionnaire, which consisted of socio-demographic variables and questions on the knowledge and challenges of learning movement disorders. Data were collected and analyzed using the Statistical Package for Social Sciences Version 20.

Results: The mean age of the study participants was 27.41±2.78 years, with a male-to-female ratio of 1.3:1. Almost (91.1%) all the study participants had heard about parkinsonism from their lectures, followed by chorea (88.6%). More than half of the participants knew about one type of movement disorder or the other. Forty-three (54.4%) students expressed difficulty understanding movement disorder lectures. Inadequate exposure to patients with movement disorders and lack of audiovisual aids to enhance the learning experience were the greatest challenges in learning movement disorders.

Conclusion: Parkinsonism was the most recognized movement disorder among the study participants. More than half of the participants admitted to having challenges with movement disorder lectures. The paucity of movement disorder cases during clinical rotation and lack of teaching aids were cited as major challenges affecting learning and appreciation of movement disorder lectures. Medical educators are encouraged to deploy appropriate methods that optimize the learning experience among medical students during movement disorder lectures.

A detailed Monte Carlo analysis is presented for six benchmark scenarios for the Higgs boson, $H_1^{0}$, these cover $m_{H_1^0}=$~120, 150 GeV and doublet-triplet mixing of $c_H=$~0.2, 0.5 or 0.8. We find that, for appropriate values of $c_H$, an excellent Higgs mass measurement is possible for the neutral Higgs in the triplet model, and discuss how to distinguish the triplet model Higgs boson from the Higgs boson of the Standard Model.

description: We define weak units in a semi-monoidal 2-category $\CC$ as cancellable pseudo-idempotents: they are pairs $(I,α)$ where $I$ is an object such that tensoring with $I$ from either side constitutes a biequivalence of $\CC$, and $α: I \tensor I \to I$ is an equivalence in $\CC$. We show that this notion of weak unit has coherence built in: Theorem A: $α$ has a canonical associator 2-cell, which automatically satisfies the pentagon equation. Theorem B: every morphism of weak units is automatically compatible with those associators. Theorem C: the 2-category of weak units is contractible if non-empty. Finally we show (Theorem E) that the notion of weak unit is equivalent to the notion obtained from the definition of tricategory: $α$ alone induces the whole family of left and right maps (indexed by the objects), as well as the whole family of Kelly 2-cells (one for each pair of objects), satisfying the relevant coherence axioms.

description: We review the basic properties of the currCFL-K^0 phase in dense quark matter. At asymptotically large densities, three-flavor quark matter is in the color-flavor locked (CFL) state. The currCFL-K^0 state is a way to respond to ``stress'' on the quark Cooper pairing, imposed at more moderate densities by the strange quark mass and the conditions of electric and color neutrality. We show how a kaon supercurrent is incorporated in a purely fermionic formalism, and show that the net current vanishes due to cancellation of fermion and charge-conjugate fermion contributions.

description: As the use of online platforms continues to grow across all demographics, users often express a desire to feel represented in the content. To improve representation in search results and recommendations, we introduce end-to-end diversification, ensuring that diverse content flows throughout the various stages of these systems, from retrieval to ranking. We develop, experiment, and deploy scalable diversification mechanisms in multiple production surfaces on the Pinterest platform, including Search, Related Products, and New User Homefeed, to improve the representation of different skin tones in beauty and fashion content. Diversification in production systems includes three components: identifying requests that will trigger diversification, ensuring diverse content is retrieved from the large content corpus during the retrieval stage, and finally, balancing the diversity-utility trade-off in a self-adjusting manner in the ranking stage. Our approaches, which evolved from using Strong-OR logical operator to bucketized retrieval at the retrieval stage and from greedy re-rankers to multi-objective optimization using determinantal point processes for the ranking stage, balances diversity and utility while enabling fast iterations and scalable expansion to diversification over multiple dimensions. Our experiments indicate that these approaches significantly improve diversity metrics, with a neutral to a positive impact on utility metrics and improved user satisfaction, both qualitatively and quantitatively, in production.

description: Progress in the theory of anomalous diffusion in weakly turbulent cold magnetized plasmas is explained. Several proposed models advanced in the literature are discussed. Emphasis is put on a new proposed mechanism for anomalous diffusion transport mechanism based on the coupled action of conductive walls (excluding electrodes) bounding the plasma drain current (edge diffusion) together with the magnetic field flux "cutting" the area traced by the charged particles in their orbital motion. The same reasoning is shown to apply to the plasma core anomalous diffusion. The proposed mechanism is expected to be valid in regimes when plasma diffusion scales as Bohm diffusion and at high $B/N$, when collisions are of secondary importance.

description: The term "Code Mixed" refers to the use of more than one language in the same text. This phenomenon is predominantly observed on social media platforms, with an increasing amount of adaptation as time goes on. It is critical to detect foreign elements in a language and process them correctly, as a considerable number of individuals are using code-mixed languages that could not be comprehended by understanding one of those languages. In this work, we focus on low-resource Hindi-English code-mixed language and enhancing the performance of different code-mixed natural language processing tasks such as sentiment analysis, emotion recognition, and hate speech identification. We perform a comparative analysis of different Transformer-based language Models pre-trained using unsupervised approaches. We have included the code-mixed models like HingBERT, HingRoBERTa, HingRoBERTa-Mixed, mBERT, and non-code-mixed models like AlBERT, BERT, and RoBERTa for comparative analysis of code-mixed Hindi-English downstream tasks. We report state-of-the-art results on respective datasets using HingBERT-based models which are specifically pre-trained on real code-mixed text. Our HingBERT-based models provide significant improvements thus highlighting the poor performance of vanilla BERT models on code-mixed text.

Publisher: name: Nigerian Medical Journal

description: Background: Nigeria remains a major contributor to neonatal deaths worldwide, yet little consideration has been given to intra/inter health facility transfer of sick neonates. The dearth of Neonatal Transport Network Services (NNTS) is probably an underappreciated driver of the abysmally high national neonatal mortality indices. This study aims to evaluate neonatal transport services among health facilities in Port Harcourt Metropolis,

Methods: Twenty-eight selected health facilities (tertiary, private hospitals Primary Health Centers] were assessed on the availability, modality and practice of NNTS. Data was analyzed using SPSS Version 23.

Results: Routine transfer of high-risk pregnant mothers to higher levels of care occurred always in 14 (50%) and sometimes in 6 (21.4%) facilities; Private cars and taxes were the most common mode of transport in 24 (85.7%) facilities. Two facilities (7.2%) had ambulances equipped with transport incubators. Nurses and nurse attendants with no formal training in NNTS accompanied referred neonates in 2 (7.2%) facilities. Most referring facilities (78.6%) neither rarely or never contacted receiving centers before the arrival of neonates and most nor gave back referrals after offering neonatal care. None (100%) of the facilities had a trained emergency transport team.

Conclusion: Health facilities in Southern Nigeria lack standardized Neonatal Transport Network characterized by poor communication between health facilities and inadequate trained personnel for inter-facility transfer of sick neonates. Urgent action is required to address these gaps, including training of healthcare workers on neonatal transport and sharing findings with relevant stakeholders/policymakers to establish a functional neonatal transport network among health facilities.

description: A comprehensive study of thermodynamic properties of three samples of bimetallic molecular magnets [Co$^{\mathrm{II}}$(pyrazole)$_{4}$]$_{2x}$[Fe$^{\mathrm{II}}$(pyrazole)$_{4}$]$_{2(1-x)}$[Nb$^{\mathrm{IV}}$(CN)$_{8}$]$\cdot$4H$_{2}$O with $x$=0 (Co$_{2}$Nb), 0.5 (CoFeNb), and 1 (Fe$_{2}$Nb) is reported. The three samples display the same crystallographic structure crystallizing in the tetragonal system with space group $I4_1/a$. Their heat capacities are measured in the temperature range 0.36-100 K without applied field as well as in the field of $μ_0 H$ = 0.1, 0.2, 0.5, 1, 2, 5, and 9 T. The results imply the presence of the second-order phase transitions to magnetically ordered phases at 4.87(8) K, 7.1(2) K, and 8.44(3) K for $x$=0, 0.5, and 1, respectively. The corresponding thermodynamic functions are analyzed to discuss the stability of the mixed compound and the magnetocaloric effect (MCE). The Gibbs energy of mixing is found to be positive but smaller in magnitude than the energy of thermal fluctuations indicating that the mixed sample is marginally stable in the full detected temperature range. The enthalpy of mixing is negative, which points to an ordered arrangement of the Co(II) and Fe(II) ions in the solid solution CoFeNb. The negative values of the entropy of mixing are explained by considering the enhanced rigidity of the crystal lattice of the solid solution sample. To extract the magnetic contribution to the heat capacity an approach based on a reasonable frequency spectrum is adopted. Taking advantage of the in-field heat capacity measurements MCE was described in terms of the isothermal entropy change $ΔS_\mathrm{M}$ and the adiabatic temperature change $ΔT_\mathrm{ad}$. The magnitudes of these quantities are typical for the class of molecular magnets.

Sassi contro il cielo Menzogna individuale e verità di Stato in Oscar Wilde

Year: 2013

description: The late Victorian era saw Oscar Wilde’s rise to success and fall from grace. For many years the Irish author lived a double life. He was both a celebrated man of letters, and an irreducibly extraneous body. His essay The Decay of Lying, published in 1889, is a Socratic dialogue that, through its inherent duplicity, exhibits this binary condition. On one hand it is a brilliant work of criticism – pleasantly heterodox – that fully embodies Wilde’s rule of “bewildering the masses”, while on the other, even though backhandedly, it gives a recalcitrant account of the implacable social control of his time. In this eulogy of the art of lying – mainly understood as a way of “saying no” to the truths of power – Wilde reveals the theoretical foundations and originality of his political philosophy, which is the same as that displayed in his later essay The Soul of Man Under Socialism (1891).

description: Recent results from experiments like PAMELA have pointed to excesses of e+e- in cosmic rays. If interpreted in terms of Dark Matter annihilations, they imply the existence of an abundant population of e+e- in the galactic halo at large. We consider the high energy gamma ray fluxes produced by Inverse Compton scattering of interstellar photons on such e+e-, and compare them with the available data from EGRET and some preliminary data from FERMI. We consider different observation regions of the sky and a range of DM masses, annihilation channels and DM profiles. We find that large portions of the parameter space are excluded, in particular for DM masses larger than 1 TeV, for leptonic annihilation channels and for benchmark Einasto or NFW profiles.

Publisher: name: University of British Columbia
Year: 2010

description: Thus study describes an investigation of the question: Is there a relationship between social functioning in the Aged, defined within a specific population sample, and the utilization of health and medical services by those persons? The results show that there is a relationship between social functioning and utilization, and that decreased social functioning correlates significantly with higher health and medical service utilization and also that intervening variables do not significantly suppress this relationship. These results suggest implications for future research and policy in dealing with the Aged in our society.

We will be concerned with Bezout special way of reducing elimination for any degree systems to finding conditions for linear systems solutions, with his typical use of indeterminate coefficients that he doesn't compute but looks only for existence and number, with his idea to work on set of polynomials products sums, and with a very personal method to found two equations resultant.

On internal wave breaking and tidal dissipation near the centre of a solar-type star

description: We study the fate of internal gravity waves, which are excited by tidal forcing by a short-period planet at the interface of convection and radiation zones, approaching the centre of a solar-type star. We study at what amplitude these wave are subject to instabilities. These instabilities lead to wave breaking whenever the amplitude exceeds a critical value. Below this value, the wave reflects perfectly from the centre of the star. Wave breaking results in spinning up the central regions of the star, and the formation of a critical layer, which acts as an absorbing barrier for ingoing waves. As these waves are absorbed, the star is spun up from the inside out. This results in an important amplitude dependence of the tidal quality factor Q'. If the tidal forcing amplitude exceeds the value required for wave breaking, efficient dissipation results over a continuous range of tidal frequencies, leading to Q' \approx 10^5 (P/1day)^(8/3), for the current Sun. This varies by less than a factor of 5 throughout the range of G and K type main sequence stars, for a given orbit. We predict fewer giant planets with orbital periods of less than about 2 days around such stars, if they cause breaking at the centre, due to the efficiency of this process. This mechanism would, however, be ineffective in stars with a convective core, such as WASP-18, WASP-12 and OGLE-TR-56, perhaps partly explaining the survival of their close planetary companions.

description: The author deals with a subject very dear to Franco Frabboni, the integrated training system, starting from the notion of territory and the analysis of the school crisis. The changes in society lead us to think of an expanded education and training system where the many educational agencies must work together for the realization operative strategies, which aretailored to the needs of the many new social subjects. It is especially in the South of Italy that this system could be fruitful and Frabboni has always looked and reflected carefully in its numerous works on these historical and social issues.

description: Transition metal dichalcogenides are known to possess large optical nonlinearities and driving these materials at high intensities is desirable for many applications. Understanding their optical responses under repetitive intense excitation is essential to improve the performance limit of these strong-field devices and to achieve efficient laser patterning. Here, we report the incubation study of monolayer MoS${}_{2}$ and WS${}_{2}$ induced by 160 fs, 800 nm pulses in air to examine how their ablation threshold scales with the number of admitted laser pulses. Both materials were shown to outperform graphene and most bulk materials; specifically, MoS${}_{2}$ is as resistant to radiation degradation as the best of the bulk thin films with a record fast saturation. Our modeling provides convincing evidence that the small reduction in threshold and fast saturation of MoS${}_{2}$ originates in its excellent bonding integrity against radiation-induced softening. Sub-ablation damages, in the forms of vacancies, lattice disorder, and nano-voids, were revealed by transmission electron microscopy, photoluminescence, Raman, and second harmonic generation studies, which were attributed to the observed incubation. For the first time, a sub-ablation damage threshold is identified for monolayer MoS${}_{2}$ to be 78% of single-shot ablation threshold, below which MoS${}_{2}$ remains intact for many laser pulses. Our results firmly establish MoS${}_{2}$ as a robust material for strong-field devices and for high-throughput laser patterning.

description: We present briefly the Nondeterministic Waiting Time algorithm. Our technique for the simulation of biochemical reaction networks has the ability to mimic the Gillespie Algorithm for some networks and solutions to ordinary differential equations for other networks, depending on the rules of the system, the kinetic rates and numbers of molecules. We provide a full description of the algorithm as well as specifics on its implementation. Some results for two well-known models are reported. We have used the algorithm to explore Fas-mediated apoptosis models in cancerous and HIV-1 infected T cells.
