description: The interactions between the spin-$1/2$ doubly charmed baryons and Nambu-Goldstone bosons are analyzed within a manifestly relativistic baryon chiral perturbation theory up to next-to-next-to leading order, by using the so-called extended-on-mass-shell scheme. We utilize heavy diquark-antiquark symmetry to estimate the low-energy constants in the chiral effective Lagrangians. The $S$- and $P$-wave scattering lengths are predicted. We find that those diagrams, vanishing exactly in the heavy-quark limit, do contribute slightly to the $S$-wave scattering lengths in reality. The influence of the spin-$3/2$ doubly charmed baryons, as heavy-quark spin partners of the spin-$1/2$ ones, on the scattering lengths is discussed as well. Finally, $S$-wave phase shifts for elastic scattering processes are presented in the energy region near threshold. Our results in this work will not only be very useful for performing chiral extrapolations of future lattice QCD data, but also provide us chiral inputs for the investigation of the spectroscopy of doubly heavy baryons.

description: Grain cleaning is the operation of a post-harvest system during which contaminants mixed with grain mass such as chaff, straw, weed seeds, soil, dust, and dirt are removed. It is a prerequisite operation in food processing. Teff cleaning involves different operations to remove those impurities for the preparation of Ethiopian staple food called injera and also for means of foreign currency. Traditionally, contaminants in teff seed are removed by winnowing by layda and mensh before separating chaff and seed on the ground until the grain is sorted from the straw and sieving to separate finer chaff and other particles from seed. This manual process is tiring, time, and energy-consuming and result in teff seed loss. Teff (Eragrostis tef) cleaner was designed and constructed based on the physical and mechanical properties of the seed, design considerations like cost and availability of materials. In order to develop solutions to solve the teff cleaning process problem, the conceptual design of the machine was performed first. Six different design concepts were developed, discussed, and modeled by SOLIDWORKS software in 2D to select one final concept that solves the problem. The cleaner works by the principle of air-screen cleaning which uses a pneumatic mechanism (fan system) to remove lightweight materials and a mechanical (sieving system) mechanism to remove materials with larger sizes. It consists of a feeding unit constructed from a conveyor to transfer grain mass mixture, a separating unit (axial fan system) constructed from four blades, the cleaning unit consists of three vibratory screens attached to shaking mechanism and power transmission components such as shafts, pulleys, belts, and bearings. The stress, strain, and deformation analysis of shafts was performed by ANSYS workbench software to determine the maximum values and the point where the maximum values have occurred. The power requirement evaluation of the machine showed that the total minimum power required to run the machine is 2.30hp. The preliminary test of the machine with three feed rates (5kg/min, 10kg/min, and 15kg/min) and three sieve inclinations (0, 5, and 10 degrees) showed that the optimum parameters of the cleaner were 5kg/min feed rate and 5-degree sieve inclination with a cleaning efficiency of 97.85% and cleaning loss of 0.87%. For better performance the design and performance analysis of the teff cleaner should be further analyzed and improved on overall performance

description: In todays digital world automated Machine Translation of one language to another has covered a long way to achieve different kinds of success stories. Whereas Babel Fish supports a good number of foreign languages and only Hindi from Indian languages, the Google Translator takes care of about 10 Indian languages. Though most of the Automated Machine Translation Systems are doing well but handling Indian languages needs a major care while handling the local proverbs/ idioms. Most of the Machine Translation system follows the direct translation approach while translating one Indian language to other. Our research at KMIT R&D Lab found that handling the local proverbs/idioms is not given enough attention by the earlier research work. This paper focuses on two of the majorly spoken Indian languages Marathi and Telugu, and translation between them. Handling proverbs and idioms of both the languages have been given a special care, and the research outcome shows a significant achievement in this direction.

description: Glass fiber reinforced composite pipes have been widely used for its high strength and high stiffness to weight ratio. The filament winding method is the manufacturing process used for glass fiber reinforced composite pipes. This study aims to present damage modeling and failure analysis of filament wound glass fiber reinforced composite pipes using continuum damage mechanics. Abaqus (version 6.14-5) commercial software was used to perform the progressive failure analysis of composite pipe based on continuum damage mechanics approach with stiffness and strength degradation. The failure analysis employs Hashin failure criteria to predict damage initiation and fracture energy-based damage evolution for the composite laminates. The numerical convergence problem is solved by using a viscous regularization model. Alternatively, the numerical implementation of the progressive damage model is presented by defining the user-defined material (UMAT) subroutine in Abaqus/CAE standard. The damage model considers four failure modes such as fiber tensile, fiber compressive, matrix tensile, and matrix compressive viscous damage variables. The failure evolutions such as failure initiation, under failure, and ultimate failure are discussed. The maximum failure pressure of numerical simulation results in ABAQUS is described. Verification of UMAT subroutine and numerical simulations of built-in material damage model in ABAQUS are considered. The results showing good agreement are obtained between them.

description: The Reynolds-averaged Navier-Stokes equation for compressible flow over supercritical airfoils under various flow conditions must be rapidly and accurately solved to shorten design cycles for such airfoils. Although deep-learning methods can effectively predict flow fields, the accuracy of these predictions near sensitive regions and their generalizability to large-scale datasets in engineering applications must be enhanced. In this study, a modified vision transformer-based encoder-decoder network is designed for the prediction of transonic flow over supercritical airfoils. In addition, four methods are designed to encode the geometric input with various information points and the performances of these methods are compared. The statistical results show that these methods generate accurate predictions over the complete flow field, with a mean absolute error on the order of 1e-4. To increase accuracy near the shock area, multilevel wavelet transformation and gradient distribution losses are introduced into the loss function. This results in the maximum error that is typically observed near the shock area decreasing by 50%. Furthermore, the models are pretrained through transfer learning on large-scale datasets and finetuned on small datasets to improve their generalizability in engineering applications. The results generated by various pretrained models demonstrate that transfer learning yields a comparable accuracy from a reduced training time.

description: Les deux axes fondamentaux de l’éducation sont l’obtention d’un niveau maximum d’autonomie, lequel repose sur la capacité de discernement, et de participation sociale. Cette dernière se centre aussi sur la sexualité. Dans ce cadre nous nous intéressons aux pratiques éducatives, autour l’éducation sexuelle, mises en place en foyer auprès des jeunes de 16 à 20 ans avec une déficience intellectuelle. Dans ce contexte, notre problématique revêt un enjeu éducatif qui découle de trois lois: la loi sur l’élimination des inégalités frappant les personnes handicapées (LHand), la loi sur la majorité sexuelle, et la loi sur la capacité de discernement. La question de l’éducation sexuelle se trouve entre ces trois lois. En fait, dans une situation où les éducateurs évaluent un jeune de 16 ans révolus comme incapable de discernement et lui empêchent d’avoir des relations sexuelles comme les autres jeunes tout-venants de son âge, ils feraient de la discrimination: ils iraient contre LHand, qui combat les discriminations et les inégalités en raison d’un handicap, et contre la loi sur la majorité sexuelle, qui donne le droit aux jeunes dès 16 ans d’avoir des relations sexuelles. La problématique repose sur la nécessité pour les professionnels de l’éducation de résoudre ce dilemme posé par ces lois. Les institutions et les professionnels de l’éducation peuvent prendre deux positions opposés par rapport à la question de (l’éducation à) la sexualité: soit permissive, soit prohibitionniste. Nos questions de recherche se basent sur la place de l’éducation sexuelle dans la prise d’autonomie et dans la participation sociale dans un foyer qui adopte un positionnement permissif, et sur comment l’enjeu éducatif est-il résolu par les éducateurs. Les résultats obtenus à travers l’étude de cas d’un foyer « permissif » mettent en évidence que l’autonomie est l’objectif principal de toutes les actions éducatives, et que la participation sociale ainsi que la sexualité sont des effets secondaires de l’autonomie. En plus, même si ce foyer se présente comme permissif et considère les jeunes comme des adultes à part entière, ses actions pédagogiques sont canalisées et quelque fois prohibitionnistes. En fait, face au dilemme qui ressort de l’enjeu éducatif, les éducateurs sont sur la défensive: pour les jeunes, le fait d’avoir des expériences sexuelles ne doit pas signifier subir des violences. Le cas échéant, ils préfèrent aller contre LHand et contre la loi sur la majorité sexuelle afin de les protéger.

description: Photonic crystals -- a class of materials whose optical properties derive from their structure in addition to their composition -- can be created by self-assembling particles whose sizes are comparable to the wavelengths of visible light. Proof-of-principle studies have shown that DNA can be used to guide the self-assembly of micrometer-sized colloidal particles into fully programmable crystal structures with photonic properties in the visible spectrum. However, the extremely temperature-sensitive kinetics of micrometer-sized DNA-functionalized particles has frustrated attempts to grow large, monodisperse crystals that are required for photonic metamaterial applications. Here we describe a robust two-step protocol for self-assembling single-domain crystals that contain millions of optical-scale DNA-functionalized particles: Monodisperse crystals are initially assembled in monodisperse droplets made by microfluidics, after which they are grown to macroscopic dimensions via seeded diffusion-limited growth. We demonstrate the generality of our approach by assembling different macroscopic single-domain photonic crystals with metamaterial properties, like structural coloration, that depend on the underlying crystal structure. By circumventing the fundamental kinetic traps intrinsic to crystallization of optical-scale DNA-coated colloids, we eliminate a key barrier to engineering photonic devices from DNA-programmed materials.

description: Pressure effect on superconducting properties of two YB6 samples (Tc = 5.9 and 7.5 K) were investigated by measurements of electrical resistivity, magnetic susceptibility, and X-ray diffraction in the pressure range up to 320 kbar. Magnetoresistivity measurements down to 60 mK and up to 47 kbar have shown a negative pressure effect on Tc as well as on the third critical field Hc3 with the slopes dlnTc/dp = -0.59%/kbar and dlnHc3/dp = -1.1%/kbar, respectively. The magnetic susceptibility measurements evidenced that the slope of dlnTc/dp gradually decreases with pressure reaching 3 times smaller value at 112 kbar. The lattice parameter measurements revealed the volume reduction of 14% at 320 kbar. The pressure-volume dependence is described by the Rose-Vinet equation of state. The obtained relative volume dependence dlnTc/dlnV analyzed by the McMillan formula for Tc indicates that the reduction of the superconducting transition temperature is mainly due to hardening of the Einstein-like phonon mode responsible for the superconducting coupling. This is confirmed by the analysis of the resistivity measurements in the normal state up to T = 300 K performed at pressures up to 28 kbar.

description: In this paper, we study a particular type of inflation by using non-local Friedman equations that are somehow derived from the zero levels of string field theory and express a tachyonic action. Then, we challenge it by further refining de Sitter (dS) swampland conjecture (FRdSSC) monitoring. Therefore, we investigate some quantities, such as potential and Hubble parameters. We also consider slow-roll parameters to examine quantities such as the scalar spectrum index and the tensor-to-scalar ratio. Using straightforward calculations, we investigate this model from the swampland conjecture perspective in terms of the cosmological parameters, i.e., ($n_s$), ($r$), and observable data such as Planck 2018, by constructing some structures such as $(c_1,2-n_s)$ and $(c_1,2-r_s)$. Then, we make a new restriction for this conjecture as $c_12c_22$ and get a limit for this model in the range $c0.0942$. We find this inflationary model is strongly in tension with the dS swampland conjecture (dSSC), i.e., $c_1=c_2 \neq \mathcal{O}(1)$. So, we shall challenge it with the FRdSSC, which has some free parameters, viz., $a,b>0$, $a+b=1$, and $q>2$. By setting these parameters, we examine the compatibility of the mentioned conjecture with this inflationary model. Finally, we infer from this string field inflation model that it satisfies the FRdSSC with the constraint of its free parameters $a$, $b$, and $q$.

description: We study the prospects for detection of continuous gravitational signals from "normal" Galactic neutron stars, i.e. non-recycled ones. We use a synthetic population generated by evolving stellar remnants in time, according to several models. We consider the most recent constraints set by all-sky searches for continuous gravitational waves and use them for our detectability criteria. We discuss detection prospects for the current and the next generation of gravitational wave detectors. We find that neutron stars whose ellipticity is solely caused by magnetic deformations cannot produce any detectable signal, not even by 3rd-generation detectors. Currently detectable sources all have $B\lesssim10^{12}$ G and deformations not solely due to the magnetic field. For these in fact we find that the larger the magnetic field is, the larger is the ellipticity required for the signal to be detectable and this ellipticity is well above the value induced by the magnetic field. Third-generation detectors as the Einstein Telescope and Cosmic Explorer will be able to detect up to $\approx 250$ more sources than current detectors. We briefly treat the case of recycled neutron stars, with a simplified model. We find that continuous gravitational waves from these objects will likely remain elusive to detection by current detectors but should be detectable with the next generation of detectors.

description: The behavior of tropical residual soils for the resolution of geotechnical engineering is a striving occurrence due to their unique physical nature of formation through the dynamic weathering process. Thus, it was necessary to require a unique empirical equation for this type of soil. Accordingly, this thesis paper explored the correlation of consolidation parameters with other easily measurable properties for soil located in Gullele Botanic Garden of Addis Ababa city. Index property, were conducted on disturbed samples, whereas, compression test were conducted on an undisturbed soil sample, further the Scanning Electron Microscopic were conducted on disturbed and an undisturbed soil sample.The Rosin–Rammler distribution function and Gompertz equation were fitted to soil textural data and compression characteristic curves, respectively. Regression analysis was used to establish a relationship among measured mechanical properties. It was observed that the clay content of the Gullele Botanic Garden ranges between 75.58% and 49.9%. The plasticity index, PI, of the soil was ranging from 9.42 to 47.56. The α and β parameters of the Rosin-Rammeler equation was in the range of 2.0 to 29.1 and 0.3 to 0.47 respectively. The coefficient of compression, Cc, of the Gompertz equation was in the range of 0.197 to 0.454. It was interesting to find a strong relationship between Cc and PI: whereas the direction of the relationship varied for Cc value at 0.2, negative for higher and positive the otherwise. In general, the study showed that tropical residual soils are very difficult to correlate measure of their physical parameters. Furthermore, testing of representative samples had revealed that the soil materials are affected by moisture variation, degree of particle size sorting, and increase stress level with load increment. Precaution is necessary on soil sample preparation and manipulation for utilizing multi-application in civil infrastructures

description: Sperm competition is a crucial aspect of male reproductive success in many species, including Drosophila melanogaster, and seminal fluid proteins (Sfps) can influence sperm competitiveness. However, the combined effect of environmental and genotypic variation on sperm competition genes' expression remains poorly understood. Here, we used Drosophila Genetic Reference Panel (DGRP) inbred lines and manipulated developmental population density (i.e. larval density) to test the effects of genotype, environment and genotype-by-environment interactions (GEI) on the expression of the known sperm competition genes Sex Peptide, Acp36DE and CG9997. High larval density resulted in reduced adult body size, but expression of sperm competition genes remained unaffected. Furthermore, we found no significant GEI but genotypic effects in the expression of SP and Acp36DE. Our results also revealed GEI for relative competitive paternity success (second male paternity; P2), with genes’ expression positively correlated with P2. Given the effect of genotype on genes' expression, we conducted a genome-wide association study (GWAS) and identified polymorphisms in putative cis-regulatory elements as predominant factors regulating the expression of SP and Acp36DE. The association of genotypic variation with sperm competition outcomes, and the resilience of sperm competition genes’ expression against environmental challenges, demonstrates the importance of genome variation background in reproductive fitness.

description: Direct experimental detection of anyonic exchange statistics in fractional quantum Hall systems by braiding the excitations and measuring the wave-function phase is an enormous challenge. Here, we use a small, noisy quantum computer to emulate direct braiding within the framework of a simplified model applicable to a thin cylinder geometry and measure the topological phase. Our algorithm first prepares the ground state with two quasiholes. It then applies a unitary operation controlled by an ancilla, corresponding to a sequence of adiabatic evolutions that takes one quasihole around the other. We finally extract the phase of the wave function from measuring the ancilla with a compound error mitigation strategy. Our results open a new avenue for studying braiding statistics in fractional Hall states.

description: In ferromagnets, electric current generally induces transverse Hall voltage in proportion to magnetization (anomalous Hall effect), and it is frequently used for electrical readout of the up and down spin states. While these properties are usually not expected in antiferromagnets, recent theoretical studies predicted that non-coplanar antiferromagnetic order with finite scalar spin chirality (i.e. solid angle spanned by neighboring spins) can often induce large spontaneous Hall effect even without net magnetization or external magnetic field. This phenomenon, i.e. spontaneous topological Hall effect, can potentially be used for the efficient electrical readout of the antiferromagnetic states, but its experimental verification has long been elusive due to the lack of appropriate materials hosting such exotic magnetism. Here, we report the discovery of all-in-all-out type non-coplanar antiferromagnetic order in triangular lattice compounds CoTa3S6 and CoNb3S6, by performing the detailed magnetic structure analysis based on polarized neutron scattering experiments as well as systematic first-principles calculations. These compounds are reported to host unconventionally large spontaneous Hall effect despite their vanishingly small net magnetization, and our analysis revealed that it can be well explained in terms of topological Hall effect, which originates from the fictitious magnetic field associated with scalar spin chirality in non-coplanar antiferromagnetic orders. The present results indicate that the scalar spin chirality mechanism can offer a promising route to realize giant spontaneous Hall response even in compensated antiferromagnets, and highlight intercalated van der Waals magnets as an unique quasi-two-dimensional material platform to enable various nontrivial manner of electrical reading and possible writing of non-coplanar antiferromagnetic domains.

description: In this work, we study magnetization dynamics in superconductor-ferromagnet (S-F) thin-film multilayer. Theoretical considerations supported by the broad-band ferromagnetic resonance spectroscopy reveal development of acoustic and optic resonance modes in S-F multilayers at significantly higher frequencies in comparison to the Kittel mode of individual F-layers. These modes are formed due to antiferromagnetic-like interaction between F-layers via shared circulating superconducting currents in S-layers. The gap between resonance modes is determined by the thickness and superconducting penetration depth in S-layers. Overall, rich spectrum of S-F multilayers and its tunability opens wide prospects for application of these multialyers in magnonics as well as in various superconducting hybrid systems.

Puis dans un deuxième temps de découvrir ce que pensent les élèves pour trouver des pistes de résolution à cette problématique. Un questionnaire proposé à plusieurs classes du secondaire I a permis de mettre en lumière les représentations que les élèves se font du bouc émissaire, du brimeur et de la situation dans sa globalité. L'analyse de leurs réponses pourraient permettre à des enseignants de mieux comprendre les sentiments de leurs élèves et peut-être de leur donner des idées pour mettre en place des stratégies pour tenter de faire disparaître ce phénomène dans leurs classes, sachant que les représentations des élèves ne sont pas toujours celles que l'on croit.

description: We study the non-linear corrections to the matter and velocity power spectra in the synchronous gauge (SG). We consider the perturbations up to third order in a zero-pressure fluid in flat cosmological background, which is relevant for the non-linear growth of cosmic structure. As a result, we point out that the SG is an inappropriate coordinate choice when handling the non-linear growth of the large-scale structure. Although the equations in the SG happen to coincide with those in the comoving gauge (CG) to linear order, they differ from second order. In particular, the second order hydrodynamic equations in the the SG are apparently in the Lagrangian form, whereas those in the CG are in the Eulerian form. Thus, the non-linear power spectra naively presented in the original SG show strange behavior quite different from the result of the Newtonian theory even on sub-horizon scales. The power spectra in the SG show regularized behaviors only after we introduce convective terms in the second order so that the equations in two gauges coincide to the second order.

description: X-ray computed tomography (CT) is one of the most common imaging techniques used to diagnose various diseases in the medical field. Its high contrast sensitivity and spatial resolution allow the physician to observe details of body parts such as bones, soft tissue, blood vessels, etc. As it involves potentially harmful radiation exposure to patients and surgeons, however, reconstructing 3D CT volume from perpendicular 2D X-ray images is considered a promising alternative, thanks to its lower radiation risk and better accessibility. This is highly challenging though, since it requires reconstruction of 3D anatomical information from 2D images with limited views, where all the information is overlapped. In this paper, we propose PerX2CT, a novel CT reconstruction framework from X-ray that reflects the perspective projection scheme. Our proposed method provides a different combination of features for each coordinate which implicitly allows the model to obtain information about the 3D location. We reveal the potential to reconstruct the selected part of CT with high resolution by properly using the coordinate-wise local and global features. Our approach shows potential for use in clinical applications with low computational complexity and fast inference time, demonstrating superior performance than baselines in multiple evaluation metrics.

description: We consider the semilinear Lane-Emden problem \begin{equation}\label{problemAbstract}\left\{ \begin{array}{lr} -Δu= |u|^{p-1}u\qquad \mbox{ in }Ω\\ u=0\qquad\qquad\qquad\mbox{ on }\partial Ω\end{array} \right.\tag{$\mathcal E_p$} \end{equation} where $p>1$ and $Ω$ is a smooth bounded symmetric domain of $\mathbb R^2$. We show that for families $(u_p)$ of sign-changing symmetric solutions of \eqref{problemAbstract} an upper bound on their Morse index implies concentration of the positive and negative part, $u_p^\pm$, at the same point, as $p\to+\infty$. Then an asymptotic analysis of $u_p^+$ and $u_p^-$ shows that the asymptotic profile of $(u_p)$, as $p\to+\infty$, is that of a tower of two different bubbles.

description: Corporate social responsibility (CSR) is the way organizations integrate social, environmental and economic concerns in a transparent and accountable manner. This study assessed practices and challenges of CSR in rebar manufacturing factory of Ethiopia. Specifically, the study addressed issues pertaining to environmental protection, employee satisfaction and employment creation, community participation, customer relation and challenges of its implementation and business sustainability. Methodologically, the study applied qualitative case studies among seven rebar manufacturing factories and institutes which are willing to participated in the study to address the research question of the study which focused on assessing the CSR practices, challenges, and its relation with business sustainability in the rebar industries of the country. The quantitative data analyzed using descriptive statistics (mean and standard deviation) while qualitative data analyzed through explanatory and thematic analysis using correlation or association and the relation between dependent and independent variables are using regression statistical method. The study also found that almost all companies have had a CSR practices towards employee, customer, community and environment and the practices also have a positive impact on a firm’s business sustainability. In Investigating the benefits and challenges that the rebar industries are faced during implementation of CSR; the study results indicated that the major benefits that the companies attained by implementing CSR contributes to build their image and reputation; reduce company’s cost by reusing waste; contributes to the businesses’ survival. Findings also showed that the government is lagged behind for encouraging and regulating of CSR practices in industries. Thus, a common CSR framework is essential for countries like Ethiopia. But it is difficult to establish a universal framework due to the different CSR practices in different cultures. Finally I recommend future study about CSR practices comparative analysis between manufacturing and service industries and I acknowledged my study advisor GEREMEW TEKLU (PHD) for his patience, motivation and guidance for successful accomplishment of my study

description: Nous avons questionné cinq femmes cheffes de famille, d’origine brésilienne, pour essayer de connaître leurs aspirations concernant l’avenir scolaire de leurs enfants. Au total, elles somment 9 enfants, ayant fréquenté, ou fréquentant encore, l’école obligatoire en Suisse. Six d’entre eux sont des primo-arrivants, c’est-à-dire, ils sont la première génération étrangère à intégrer le système scolaire suisse. Quelles sont les attentes maternelles sur l’avenir scolaire de ces six primo-arrivants ? Luzie 53 ans, Elsa 47 ans, Paula 41 ans, Diana 40 ans, et Hélène 37 ans, 5 femmes d’origine ethnique et confession religieuse différentes présentant des parcours migratoire similaires.3 Les mères cheffes de famille qui ont participé à cette recherche appartiennent aux classes défavorisées, à la fois au Brésil et en Suisse. Toutes ces femmes ont ramené leurs enfants en Suisse malgré le manque de permis de séjour valable. Trois d’entre elles vivent toujours dans l’illégalité. Pourquoi ces mères imposent à leurs enfants de vivre dans la précarité sociale ? Notre objectif est d’analyser leurs attentes et les confronter aux théories de l’intersectionnalité afin de comprendre comment les problématiques de genre, de classe et d’immigration influencent les attentes des mères sur l’avenir scolaire de leurs enfants.

description: High performance calorimetry conducted at future hadron colliders, such as the FCC-hh, poses a significant challenge for applying current detector technologies due to unprecedented beam luminosities and radiation fields. Solutions include developing scintillators that are capable of separating events at the sub-fifty picosecond level while also maintaining performance after extreme and constant neutron and ionizing radiation exposure. The RADiCAL is an approach that incorporates radiation tolerant materials in a sampling 'shashlik' style calorimeter configuration, using quartz capillaries filled with organic liquid or polymer-based wavelength shifters embedded in layers of tungsten plates and LYSO crystals. This novel design intends to address the Priority Research Directions (PRD) for calorimetry listed in the DOE Basic Research Needs (BRN) workshop for HEP Instrumentation. Here we report preliminary results from an experimental run at the Fermilab Test Beam Facility in June 2022. These tests demonstrate that the RADiCAL concept is capable of < 50 ps timing resolution.

description: Tuning forks are very popular experimental tools widely applied in low and ultra low temperature physics as mechanical resonators and cantilevers in the study of quantum liquids, STM and AFM techniques, etc. As an added benefit, these forks being cooled, have very high Q-value, typically $10^6$ and their properties seems to be magnetic field independent. We present preliminary vacuum measurements of a commercial tuning fork oscillating at frequency 32~kHz conducted in magnetic fields up to 8~T and at temperature $\sim 10$~mK. We found an additional weak damping of the tuning fork motion depending on magnetic field magnitude and we discuss physical nature of the observed phenomena.

description: We present a new photometric identification technique for SN 1991bg-like type Ia supernovae (SNe Ia), i.e. objects with light-curve characteristics such as later primary maxima and absence of secondary peak in redder filters. This method is capable of selecting out this sub-group from the normal type Ia population. Furthermore, we find that recently identified peculiar sub-types such as SNe Iax and super-Chandrasekhar SNe Ia have similar photometric characteristics as 91bg-like SNe Ia, namely the absence of secondary maxima and shoulders at longer wavelengths, and can also be classified with our technique. The similarity of these different SN Ia sub-groups perhaps suggests common physical conditions. This typing methodology permits the photometric identification of peculiar SNe Ia in large up-coming wide field surveys either to study them further or to obtain a pure sample of normal SNe Ia for cosmological studies.
