Nomada fuscicornis

description: Nomada fuscicornis Nylander, 1848. Statut (Belgique): EN
Contrairement à la plupart des Nomada dont les hôtes appartiennent au genre Andrena, la nomade antennes-brunes (Nomada fuscicornis, Fig. 25) est cleptoparasite du genre Panurgus et plus particulièrement, de l’espèce Panurgus calcaratus (SMIT, 2018). La période de vol de Nomada fuscicornis s’étend de juillet à septembre et l’espÈce affectionnerait les mÊmes milieux que son hôte (WESTRICH, 2019). Panurgus calcaratus est une espèce sabulicole oligolectique sur Asteraceae (WESTRICH, 2019). Les spécimens de Panurgus capturés dans le Hainaut fréquentaient effectivement les genres Picris, Crepis, Hypochaeris, etc. Le spécimen de Nomada fuscicornis à quant à lui été capturé au sol, dans la réserve naturelle de la Mer de Sable où l’on retrouve son hôte en abondance.
Dans l’idée d’aménager des sites propices à l’hôte, des bancs sablonneux pourraient Être plantés d’espÈces d’Asteraceae. Afin de conserver un accÈs au substrat et permettre la nidification, nous recommandons l’utilisation d’espèces à faible recouvrement comme Hieracium pilosella (FRANÇOIS et al., 2017).

description: We study 2-dimensional submanifolds of the space ${\mathbb{L}}({\mathbb{H}}^3)$ of oriented geodesics of hyperbolic 3-space, endowed with the canonical neutral Kähler structure. Such a surface is Lagrangian iff there exists a surface in ${\mathbb{H}}^3$ orthogonal to the geodesics of $Σ$. We prove that the induced metric on a Lagrangian surface in ${\mathbb{L}}({\mathbb{H}}^3)$ has zero Gauss curvature iff the orthogonal surfaces in ${\mathbb{H}}^3$ are Weingarten: the eigenvalues of the second fundamental form are functionally related. We then classify the totally null surfaces in ${\mathbb{L}}({\mathbb{H}}^3)$ and recover the well-known holomorphic constructions of flat and CMC 1 surfaces in ${\mathbb{H}}^3$.

description: We present the first detection and mapping of the HD 32297 debris disk at 1.3 mm with the Combined Array for Research in Millimeter-wave Astronomy (CARMA). With a sub-arcsecond beam, this detection represents the highest angular resolution (sub)mm debris disk observation made to date. Our model fits to the spectral energy distribution from the CARMA flux and new Spitzer MIPS photometry support the earlier suggestion that at least two, possibly three, distinct grain populations are traced by the current data. The observed millimeter map shows an asymmetry between the northeast and southwest disk lobes, suggesting large grains may be trapped in resonance with an unseen exoplanet. Alternatively, the observed morphology could result from the recent breakup of a massive planetesimal. A similar-scale asymmetry is also observed in scattered light but not in the mid-infrared. This contrast between asymmetry at short and long wavelengths and symmetry at intermediate wavelengths is in qualitative agreement with predictions of resonant debris disk models. With resolved observations in several bands spanning over three decades in wavelength, HD 32297 provides a unique testbed for theories of grain and planetary dynamics, and could potentially provide strong multi-wavelength evidence for an exoplanetary system.

description: Nomada integra Brullé, 1832. Statut (Belgique): VU
La nomade de l’épervière (Nomada integra, Fig. 26) est cleptoparasite de l’espèce Andrena humilis et vole entre avril et juin (WESTRICH, 2019). Selon PEETERS et al. (2012), l’espèce affectionnerait les milieux secs et chauds. Les trois spécimens capturés se partagent entre des prairies et le parc universitaire de la ville de Mons (Nimy). L’hôte, Andrena humilis, est une espèce oligolectique sur la tribu des Cichorieae (Taraxacum, Crepis, etc) et affectionnerait les prairies à gestion extensive (PEETERS et al., 2012; WESTRICH, 2019), comme semble le confirmer notre échantillon (56% des effectifs sont répartis dans ce milieu). En second lieu, l’hôte a été retrouvé en assez grand nombre dans les parcs (20% des effectifs).
Si Nomada integra et son hôte semblent pouvoir s’accommoder du milieu urbain, des mesures de gestion appropriées dans les parcs permettraient peut-être d’en accroître les populations. Ces mesures pourraient notamment concerner la préservation de certaines « mauvaises herbes » dans les pelouses (Hypochaeris, Crepis, Leontodon, Taraxacum, etc), celles-ci constituant l’essentiel de l’alimentation d’ Andrena humilis. De mÊme, l’hôte pourrait Être favorisé par le tracé de chemins de terre, cette espÈce affectionnant les sols compacts pour l’établissement de ses nids (PEETERS et al., 2012).

description: Qajar adalah sebuah kekuatan politik Persia (sekarang Iran) yang berkuasa dalam rentang waktu cukup lama sejak 1796 hingga 1925. Tulisan ini berusaha untuk mengungkap peristiwa-peristiwa penting dalam pemerintahan pengusa Qajar ketiga yakni di bawah Muhammad Shah dengan rentang waktu kekuasaannya sejak 1834 hingga wafatnya pada 1848. Metodologi penelitian yang dipakai adalah metode historis dengan langkah-langkahnya yakni pemilihan topik, pengumpulan sumber, verifikasi secara internal untuk menilai validitas kesaksian dalam sumber, melakukan penafsiran / interpretasi dan melakukan penulisan sejarah (historiografi). Hasil penelitian ini menunjukkan bahwa peristiwa-peristiwa penting di masa kekuasaan Muhammad Shah ialah diawali usaha invasi atas Afghanistan yang gagal pada 1838. Muhammad Shah melancarkan kampanye militer lain melawan Agha Khan I pemimpin sekte Ismailiyah untuk mengganti posisinya sebagai penguasa Kerman. Agha Khan yang kalah kemudian mengungsi dan membangun basis sektenya di India. Peristiwa sangat penting berikutnya adalah kelahiran agama Babiyah di bawah Sayyid Ali yang berhasil mengguncang stabilitas politik dan sosial Persia antara tahun 1844 hingga kematian Muhammad Shah pada 1848 M

description: Sphecodes niger von Hagens, 1874. Statut (Belgique): VU
Le sphécode noir, Sphecodes niger (Fig. 28), est une espèce clepoparasite rare (seulement 55 individus dans la base de données régionale; FOLSCHWEILLER et al., 2020 b) volant de mai à juin pour les individus sortant de diapause et de juillet à octobre pour la génération estivale (WESTRICH, 2019). L’espèce fréquenterait les prairies calcaires et les carrières (PEETERS et al., 2012). L’unique capture de notre inventaire provient d’une petite prairie calcaire dissimulée dans un quartier résidentiel et protégée par le statut de réserve naturelle. L’hôte principale est Lasioglossum morio (WESTRICH, 2019), l’un des Halictidae les plus abondants de notre échantillon. Ce Lasioglossum est une espèce ubiquiste, polylectique et très adaptable lors de la réalisation de ses nids (WESTRICH, 2019). Dans ce contexte, la fragmentation de l’habitat (DROSSART et al., 2019) semble jouer un rôle plus important dans la vulnérabilité de l’espèce que la raréfaction de son hôte. Notre principale recommandation consiste donc à protéger ou restaurer les habitats calcaires dont l’espèce dépend.
Dans la littérature, l’espÈce est connue pour visiter Achillea millefolium, Daucus carota et Senecio jacobaea (PEETERS et al., 2012; WESTRICH, 2019). Notre individu à quant à lui été collecté sur Heracleum sphondylium. Ces fleurs pourraient donc rejoindre la composition des mélanges floraux proposés dans les aménagements destinés aux pollinisateurs. En effet, par le passé, ceux-ci se focalisaient assez fortement sur les Fabacaeae, probablement car ils avaient été pensés pour soutenir les populations de bourdons (WOOD et al., 2015; WOOD et al., 2017).

description: Non-standard physics which can be described by effective four fermion interactions may be an additional source of CP violation in the neutrino propagation. We discuss the detectability of such a CP violation at a neutrino factory. We assume the current baseline setup of the international design study of a neutrino factory (IDS-NF) for the simulation. We find that the CP violation from certain non-standard interactions is, in principle, detectable significantly below their current bounds -- even if there is no CP violation in the standard oscillation framework. Therefore, a new physics effect might be mis-interpreted as the canonical Dirac CP violation, and a possibly even more exciting effect might be missed.

description: Image virtual try-on task has abundant applications and has become a hot research topic recently. Existing 2D image-based virtual try-on methods aim to transfer a target clothing image onto a reference person, which has two main disadvantages: cannot control the size and length precisely; unable to accurately estimate the user's figure in the case of users wearing thick clothes, resulting in inaccurate dressing effect. In this paper, we put forward an akin task that aims to dress clothing for underwear models. %, which is also an urgent need in e-commerce scenarios. To solve the above drawbacks, we propose a Shape Controllable Virtual Try-On Network (SC-VTON), where a graph attention network integrates the information of model and clothing to generate the warped clothing image. In addition, the control points are incorporated into SC-VTON for the desired clothing shape. Furthermore, by adding a Splitting Network and a Synthesis Network, we can use clothing/model pair data to help optimize the deformation module and generalize the task to the typical virtual try-on task. Extensive experiments show that the proposed method can achieve accurate shape control. Meanwhile, compared with other methods, our method can generate high-resolution results with detailed textures.

description: Models which accelerate the expansion of the universe through the addition of a function of the Ricci scalar f(R) leave a characteristic signature in the large-scale structure of the universe at the Compton wavelength scale of the extra scalar degree of freedom. We search for such a signature in current cosmological data sets: the WMAP cosmic microwave background (CMB) power spectrum, SNLS supernovae distance measures, the SDSS luminous red galaxy power spectrum, and galaxy-CMB angular correlations. Due to theoretical uncertainties in the nonlinear evolution of f(R) models, the galaxy power spectrum conservatively yields only weak constraints on the models despite the strong predicted signature in the linear matter power spectrum. Currently the tightest constraints involve the modification to the integrated Sachs-Wolfe effect from growth of gravitational potentials during the acceleration epoch. This effect is manifest for large Compton wavelengths in enhanced low multipole power in the CMB and anti-correlation between the CMB and tracers of the potential. They place a bound on the Compton wavelength of the field be less than of order the Hubble scale.

description: As robots operate in increasingly complex and dynamic environments, fast motion re-planning has become a widely explored area of research. In a real-world deployment, we often lack the ability to fully observe the environment at all times, giving rise to the challenge of determining how to best perceive the environment given a continuously updated motion plan. We provide the first investigation into a `smart' controller for gaze control with the objective of providing effective perception of the environment for obstacle avoidance and motion planning in dynamic and unknown environments. We detail the novel problem of determining the best head camera behaviour for mobile robots when constrained by a trajectory. Furthermore, we propose a greedy optimisation-based solution that uses a combination of voxelised rewards and motion primitives. We demonstrate that our method outperforms the benchmark methods in 2D and 3D environments, in respect of both the ability to explore the local surroundings, as well as in a superior success rate of finding collision-free trajectories -- our method is shown to provide 7.4x better map exploration while consistently achieving a higher success rate for generating collision-free trajectories. We verify our findings on a physical Toyota Human Support Robot (HSR) using a GPU-accelerated perception framework.

The associated objects have an geometric character. Some fractional dynamical systems on a fractional Leibniz algebroid are disscussed.

description: We estimate cluster ages from lithium depletion in five pre-main-sequence groups found within 100 pc of the Sun: TW Hydrae Association, Eta Chamaeleontis Cluster, Beta Pictoris Moving Group, Tucanae-Horologium Association and AB Doradus Moving Group. We determine surface gravities, effective temperatures and lithium abundances for over 900 spectra through least squares fitting to model-atmosphere spectra. For each group, we compare the dependence of lithium abundance on temperature with isochrones from pre-main-sequence evolutionary tracks to obtain model dependent ages. We find that the Eta Chamaelontis Cluster and the TW Hydrae Association are the youngest, with ages of 12+/-6 Myr and 12+/-8 Myr, respectively, followed by the Beta Pictoris Moving Group at 21+/-9 Myr, the Tucanae-Horologium Association at 27+/-11 Myr, and the AB Doradus Moving Group at an age of at least 45 Myr (where we can only set a lower limit since the models -- unlike real stars -- do not show much lithium depletion beyond this age). Here, the ordering is robust, but the precise ages depend on our choice of both atmospheric and evolutionary models. As a result, while our ages are consistent with estimates based on Hertzsprung-Russell isochrone fitting and dynamical expansion, they are not yet more precise. Our observations do show that with improved models, much stronger constraints should be feasible: the intrinsic uncertainties, as measured from the scatter between measurements from different spectra of the same star, are very low: around 10 K in effective temperature, 0.05 dex in surface gravity, and 0.03 dex in lithium abundance.

description: AbstractMetal–organic frameworks with diverse structures and unique properties have demonstrated that can be an ideal substitute for natural enzymes in colorimetric sensing platform for analyte detection in various fields such as environmental chemistry, biotechnology and clinical diagnostics, which have attracted the scientist’s attention, recently. In this study, a porous coordination network (denoted as PCN-222) was synthesized as a new biomimetic material from an iron linked tetrakis (4-carboxyphenyl) porphyrin (named as Fe-TCPP) as a heme-like ligand and Zr6 linker as a node. This catalyst shows the peroxidase and catalase activities clearly. The mechanism of peroxidase activity for PCN-222 was investigated using the spectrophotometric methods and its activity was compared with the other nanoparticles which, the results showed a higher activity than the other catalysts. Also, the hydrogen peroxide was detected by PCN-222(Fe) based on the peroxidase-like activity. For detection of hydrogen peroxide a linear range of 3–200 μM and detection of limit (LOD) 1 μM (3σ/slope), under optimal conditions were obtained. Moreover, based on the high tendency of PCN-222(Fe) to combine with the TMB as a chromogenic substrate in the peroxidase-like activity, we developed the sensitive and selective colorimetric assay for glucose detection that was found a detection limit (LOD) of 2.2 μM in the linear range from 12 to 75 μM. Finally due to the good catalytic activity of PCN-222(Fe), it was used to detection of glucose and hydrogen peroxide in real samples.

We also describe the set of dimensions of all indecomposable unitary (Euclidean) representations of a quiver and establish the number of parameters in an indecomposable unitary representation of a given dimension.
Leptogenesis and dark matter unified in a non-SUSY model for neutrino masses

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose a unified explanation for the origin of dark matter and baryon number asymmetry on the basis of a non-supersymmetric model for neutrino masses. Neutrino masses are generated in two distinct ways, that is, a tree-level seesaw mechanism with a single right-handed neutrino, and one-loop radiative effects by a new additional doublet scalar. A spontaneously broken U(1)$^\prime$ brings a $Z_2$ symmetry which restricts couplings of this new scalar and controls the neutrino masses. It also guarantees the stability of a CDM candidate. We examine two possible candidate for the CDM. We also show that the decay of a heavy right-handed neutrino related to the seesaw mechanism can generate baryon number asymmetry through leptogenesis.

description: The Mott insulating perovskite KCuF3 is considered the archetype of an orbitally-ordered system. By using the LDA+dynamical mean-field theory (DMFT) method, we investigate the mechanism for orbital-ordering (OO) in this material. We show that the purely electronic Kugel-Khomskii super-exchange mechanism (KK) alone leads to a remarkably large transition temperature of T_KK about 350 K. However, orbital-order is experimentally believed to persist to at least 800 K. Thus Jahn-Teller distortions are essential for stabilizing orbital-order at such high temperatures.

We propose modifications of the inverted Wishart and matrix $t$ distributions, replacing the scalar degrees of freedom by a diagonal matrix of degrees of freedom. The MV-DLM is then re-defined and modifications of the updating algorithm for missing observations are suggested.

description: Using absorbance measurements through a Couette cell containing an emulsion of buoyant droplets, volume fraction profiles are measured at various shear rates. These viscous resuspension experiments allow a direct determination of the normal stress in the vorticity direction in connection with the suspension balance model that has been developed for suspensions of solid particles. The results unambigously show that the normal viscosity responsible for the shear-induced migration of the droplets is independant on the capillary number, implying that particle deformation does not play a great role. It is similar to that of rigid particles at volume fractions below 40\% but much smaller at higher ones.

La mélitte de l’odontite, Melitta tricincta (Fig. 23), est une abeille solitaire apparaissant à la fin de l’été (août-septembre). L’espèce creuse son nid dans le sol sans présenter de préférence pour un substrat particulier. En revanche, les espaces de nidification se situent toujours à proximité de fleurs du genre Odontites, les femelles utilisant ces dernières comme unique source de pollen (PEETERS et al., 2012; DELLICOUR et al., 2015; WESTRICH, 2019). Les habitats fréquentés sont nombreux mais généralement xérothermophiles (MACEK et al., 2010). Les quatre spécimens collectés proviennent d’un terril et d’une prairie.
Les Odontites peuvent s’épanouir en grand nombre sur les talus et bords de routes. WESTRICH (2020) considère d’ailleurs ces milieux comme des habitats d’importance pour Melitta tricincta. Pour y maintenir la présence des Odontites, on recommande l’utilisation d’un fauchage annuel entre les mois de septembre et mai (WESTRICH, 2020). Un ensemencement serait également envisageable par l’intermédiaire de mesures agro-environnementales.

description: Children’s literature in India has undergone significant transformation over the past decade. Moving beyond traditional, didactic narratives, modern literature embraces diverse themes, perspectives, and intersectionality. Contemporary works depict real-life issues such as caste, gender, disability, and societal inequities, fostering empathy and inclusivity. Visual storytelling, too, has evolved, with illustrators playing a pivotal role in addressing mature themes. This paper explores these shifts, presenting a comprehensive review of notable works and their contributions to authentic and transformative storytelling for children.

Seladonia confusa

description: Seladonia confusa (Blüthgen 1926). Statut (Belgique): VU
L’halicte confus (Seladonia confusa, Fig. 27) est une espèce polylectique et sabulicole dont le mode de vie serait possiblement eusocial (DOLPHIN, 1966; PEETERS et al., 2012; WESTRICH, 2019). La période de vol débuterait dès le mois d’avril pour les femelles hivernantes, et s’étendrait de juillet à septembre pour les individus émergeant en été (WESTRICH, 2019). Les spécimens collectés proviennent d’un terril, d’une aire sablonneuse et d’une ancienne sablière, illustrant ainsi la nécessité d’un substrat adéquat pour la nidification de cette espÈce. La vulnérabilité de l’halicte confus à l’échelle belge est en effet directement associée à la fragilité de son habitat (DROSSART et al., 2019). En Wallonie en particulier, ce taxon était connu pour se cantonner presque exclusivement aux sablières (PAULY, 2017c). De ce fait, sa conservation ne peut s’envisager sans la mise en place de mesures visant à protéger les aires sablonneuses existantes. Ajoutons ici qu’en dehors des sablières dont la répartition est relativement limitée, le vaste réseau de terrils de la province pourrait également participer à la conservation de l’espèce. Si aux Pays-Bas, l’espèce semble ne pas s’approcher des villes (PEETERS et al., 2012), en Belgique, celle-ci a déjà été collectée dans des potagers urbains (PAULY et al., 2019). Des aménagements dans les parcs destinés à l’ensemble des espèces sabulicoles pourraient donc s’avérer bénéfiques (ex: bacs à sable, « carrés de sols »; FORTEL et al., 2016).

Time-dependent and time-integrated angular analysis of $B\toϕK^0_Sπ^0$ and $ϕK^\pmπ^\mp$

description: We perform a time-dependent and time-integrated angular analysis of the decays $B^0\toϕK^{*}(892)^0$, $ϕK^{*}_2(1430)^0$, and $ϕ(Kπ)^{*0}_{0}$ with the final sample of about 465 million $\BB$ pairs recorded with the $\babar$ detector. Twenty-four parameters are investigated, including the branching fractions, CP-violation parameters, and parameters sensitive to final-state interactions. We use the dependence on the $Kπ$ invariant mass of the interference between the scalar and vector or tensor components to resolve discrete ambiguities of the strong and weak phases. We use the time-evolution of the $B\toϕK^0_Sπ^0$ channel to extract the CP-violation phase difference $Δϕ_{00}=0.28\pm0.42\pm 0.04$ between the $B$ and $\Bbar$ decay amplitudes. When the $B\toϕK^\pmπ^\mp$ channel is included, the fractions of longitudinal polarization ${f_L}$ of the vector-vector and vector-tensor decay modes are measured to be $0.494\pm0.034\pm0.013$ and $0.901^{+0.046}_{-0.058}\pm 0.037$, respectively. This polarization pattern requires the presence of a positive-helicity amplitude in the vector-vector decay from a currently unknown source.

Sphecodes scabricollis

description: Sphecodes scabricollis Wesmael, 1835. Statut (Belgique): EN
Le sphécode anguleux, Sphecodes scabricollis (Fig. 29), n’est représenté que par 50 individus dans les bases de données régionales (FOLSCHWEILLER et al., 2020b). Sa période de vol s’étendrait de mai à septembre (WESTRICH, 2019). D’aprÈs les données réunies au Pays-Bas, l’espèce fréquenterait les espaces de végétation clairsemée sur sols sablo-limoneux (PEETERS et al., 2012). Ce sphécode est cleptoparasite de Lasioglossum zonulum, une espèce polylectique affectionnant le mÊme type d’habitats et souvent retrouvée à proximité de sols humides (PEETERS et al., 2012). Sphecodes scabricollis aurait déjà été observé sur les fleurs de Daucus carota, ou encore sur le genre Solidago. Inclure ces espÈces dans les mélanges floraux proposés dans le cadre des méthodes agro-environnementales pourrait donc s’avérer utile pour la conservation de l’espèce.
Les deux spécimens capturés proviennent du Bois de Bon-Secours, sur une parcelle au sol sablo-limoneux. L’hôte n’a pas été collecté sur ce site et, réciproquement, Lasioglossum zonulum a été collecté dans des friches, carrières, prairies et terrils dont son parasite est pour l’instant absent. Cette incohérence laisse supposer que l’échantillonnage de ces espèces est encore incomplet. Un effort de collecte accru permettrait de mieux cerner l’écologie de l’espÈce afin d’affiner les mesures de conservation.

description: In this paper, we consider the problem of resource allocation among two competing users sharing a binary symmetric broadcast channel. We model the interaction between autonomous selfish users in the resource allocation and analyze their strategic behavior in manipulating the allocation outcome. We analytically show that users will improve their performance (i.e. gain higher allocated rates) if they have more information about the strategy of the competing user.

description: AbstractWe report the synthesis of a composite from cobalt porphyrin-based metal organic framework (MOF) and multi-walled carbon nanotube (MWCNT), possessing good catalytic activity toward oxygen reduction (OR) and oxygen evolution (OE) processes. A 3-D porous coordination network (PCN) with 3-D nanochannels was synthesized using ultrastable Zr6 clusters and tetrakis(4-carboxyphenyl)porphyrin cobalt(II). Located in the backbone of MOF, cobalt porphyrins as the active centers are easily accessible to the reactants. The composite exhibits smaller overpotentials and higher current for OR and OE reactions compared to the commercial Pt/C catalyst. A proton-coupled electron transfer mechanism has been suggested due to the pH dependence of water oxidation on the electrocatalyst. Furthermore, the stability of the catalyst has been verified by various techniques. Our designed heterogeneous, inexpensive, and stable electrocatalyst is a proper candidate for acidic fuel cells and water splitting devices under near neutral condition without requirement of pyrolysis process.

description: We study the problem of pattern selection in an array of parametrically-driven nonlinear resonators with application to microelectromechanical and nanoelectromechanical systems (MEMS & NEMS), using an amplitude equation recently derived by Bromberg, Cross, and Lifshitz [PRE 73, 016214 (2006)]. We describe the transitions between standing-wave patterns of different wave numbers as the drive amplitude is varied either quasistatically, abruptly, or as a linear ramp in time. We find novel hysteretic effects, which are confirmed by numerical integration of the original equations of motion of the interacting nonlinear resonators.

description: We present a deep-learning artificial intelligence model that is capable of learning and forecasting the late-inspiral, merger and ringdown of numerical relativity waveforms that describe quasi-circular, spinning, non-precessing binary black hole mergers. We used the NRHybSur3dq8 surrogate model to produce train, validation and test sets of $\ell=|m|=2$ waveforms that cover the parameter space of binary black hole mergers with mass-ratios $q\leq8$ and individual spins $|s^z_{\{1,2\}}| \leq 0.8$. These waveforms cover the time range $t\in[-5000\textrm{M}, 130\textrm{M}]$, where $t=0M$ marks the merger event, defined as the maximum value of the waveform amplitude. We harnessed the ThetaGPU supercomputer at the Argonne Leadership Computing Facility to train our AI model using a training set of 1.5 million waveforms. We used 16 NVIDIA DGX A100 nodes, each consisting of 8 NVIDIA A100 Tensor Core GPUs and 2 AMD Rome CPUs, to fully train our model within 3.5 hours. Our findings show that artificial intelligence can accurately forecast the dynamical evolution of numerical relativity waveforms in the time range $t\in[-100\textrm{M}, 130\textrm{M}]$. Sampling a test set of 190,000 waveforms, we find that the average overlap between target and predicted waveforms is $\gtrsim99\%$ over the entire parameter space under consideration. We also combined scientific visualization and accelerated computing to identify what components of our model take in knowledge from the early and late-time waveform evolution to accurately forecast the latter part of numerical relativity waveforms. This work aims to accelerate the creation of scalable, computationally efficient and interpretable artificial intelligence models for gravitational wave astrophysics.

description: A progressão das legislações e o enfraquecimento das políticas públicas têm contribuído para a intensificação das desigualdades no país, refletindo-se numa produção normativa em contextos de exclusão e subcidadania. Os atuais procedimentos penais brasileiros, são reflexos de um passado marcado pelo preconceito racial e pela marginalização do indivíduo condições que permeiam tanto a sociedade quanto as próprias instituições estatais. Esses elementos, por sua vez, culminam na racialização do sistema de justiça criminal e no encarceramento em massa da população. O projeto de modernização do Brasil nunca pretendeu incorporar a população negra, entendiam "modernizar" como embranquecer a sociedade brasileira.

description: Recently published measurements of the branching ratios ${\cal B}(ψ(1S)\to\ga η_C(1S))$ and ${\cal B}(ψ(2S)\to\ga η_C(1S))$ by the CLEO collaboration are examined in the context of a potential model that includes both relativistic and one-loop QCD corrections to the quark-antiquark interaction. The prediction for the width $Γ(ψ(1S)\to\ga η_C(1S))$ is in excellent agreement with the new data but the prediction for $Γ(ψ(2S)\to\ga η_C(1S))$ is too small. In an effort to understand this discrepancy, we derive an upper bound on $Γ(ψ(2S)\to\ga η_C(1S))$ and point out its experimental value saturates this bound.

Social modeling influences on self-report and facial expression indices of cold-induced pain
Creators: name: Patrick, Christopher John
Publisher: name: University of British Columbia
Year: 2010

description: Socialization has been identified as one important source of individual differences in pain expression (Craig, 1980). Previous laboratory studies (e.g. Craig, 1978a; Craig & Coren, 1975; Craig & Prkachin, 1978) had shown that self-report, physiological, and psychophysical indices of electric shock-induced pain could be influenced by social modeling. The present study attempted to replicate these findings using a different noxious stimulus, the cold pressor test, and two separate indices of the pain experience - self-report and facial expression. Subjects (72 female introductory psychology students, ages 17 to 25 years) undertook the cold pressor test and rated their discomfort in the presence of either a tolerant, an intolerant, or an inactive model. Half the subjects in each of these three groups were permitted to see both the model and the model's ratings of discomfort (visual condition); the other half were screened from the model, and saw only the model's discomfort ratings (nonvisual condition). Subjects' facial expressions were videotaped during the cold pressor test and subsequently scored using the Facial Action Coding System (Ekman & Friesen, 1978b). It was hypothesized that subjects exposed to a tolerant model would report less pain, endure the cold pressor for a longer period of time, and show fewer facial signs of pain than control group subjects; intolerant-modeling subjects were expected to show more distress on both self-report and facial measures. Moreover, modeling group differences in facial expression were expected to be more pronounced in the visual condition. The results indicated that only self-report indices of pain were influenced by the modeling manipulation, even in the visual condition. However, further analyses suqgested that facial indices of pain do not covary with self-report, even amongst control subjects; facial signs of distress were most prominent at the onset of noxious stimulation, although self-reported discomfort increased over exposure time. The results were discussed in light of past research on cold-induced pain (e.q. Wolf & Hardy, 1941). Also, facial actions associated with pain in the present study were contrasted with earlier descriptions of the pain expression (Hjortsjo, 1969). Finally, a discussion was made of implications for future research.
