Response time of photoemission at quantum-classic boundary

The response time of the electron to light in photoemission is difficult to define and measure. Tunneling ionization of atoms, a strong-laser-induced photoemission process, provides a semiclassical case for visiting the problem. Here, we show that the response time can be determined at the boundary between quantum and classic. Specifically, tunneling is instantaneous but a finite response time (about 100 attoseconds) is needed for the state of the tunneling electron to evolve into the ionized state around tunnel exit. This time can be well described with a compact expression related to some basic laser and atomic parameters. Moreover, it can be directly mapped to and easily decoded from photoelectron momentum with a simple mapping, allowing an unambiguous measurement. These results shed light on definition and measurement of the response time of photoemission.
Self-supervised models of audio effectively explain human cortical responses to speech

Self-supervised language models are very effective at predicting high-level cortical responses during language comprehension. However, the best current models of lower-level auditory processing in the human brain rely on either hand-constructed acoustic ﬁlters or representations from supervised audio neural networks. In this work, we capi-talize on the progress of self-supervised speech representation learning (SSL) to create new state-of-the-art models of the human auditory system. Compared against acoustic baselines, phonemic features, and supervised models, representations from the middle layers of self-supervised models (APC, wav2vec, wav2vec 2.0, and HuBERT) con-sistently yield the best prediction performance for fMRI recordings within the auditory cortex (AC). Brain areas involved in low-level auditory processing exhibit a preference for earlier SSL model layers, whereas higher-level semantic areas prefer later layers. We show that these trends are due to the models’ ability to encode information at multiple linguistic levels (acoustic, phonetic, and lexical) along their representation depth. Overall, these results show that self-supervised models effectively capture the hierarchy of information relevant to different stages of speech processing in human cortex.
Exemplar Free Class Agnostic Counting

We tackle the task of Class Agnostic Counting, which aims to count objects in a novel object category at test time without any access to labeled training data for that category. All previous class agnostic counting methods cannot work in a fully automated setting, and require computationally expensive test time adaptation. To address these challenges, we propose a visual counter which operates in a fully automated setting and does not require any test time adaptation. Our proposed approach first identifies exemplars from repeating objects in an image, and then counts the repeating objects. We propose a novel region proposal network for identifying the exemplars. After identifying the exemplars, we obtain the corresponding count by using a density estimation based Visual Counter. We evaluate our proposed approach on FSC-147 dataset, and show that it achieves superior performance compared to the existing approaches.
Safe liquid scintillators for large scale detectors

Many experiments in particle physics, in particular in the field of neutrino searches, rely on organic liquid scintillators as target and detection material. The size of these detectors was continously growing in the last decades, up to the kiloton scale. In several cases these detectors are located at sites with enhanced safety requirements such as underground laboratories or in the vicinity of nuclear reactors. Therefore, there is strong demand in liquids which are safe with respect to aspects such as fire protection, human health or environmental pollution. The flash point, the vapor pressure or the toxicity need to be significantly improved as compared to classical solvents such as xylene or pseudocumene. We present and compare the performance and optical properties of scintillators based on high flash point solvents. In particular, polysiloxane based scintillators are characterized by outstanding properties in terms of safety.
Non-adiabatic corrections to chiral charge pumping in topological nodal semimetals

Studying many-body versions of Landau-Zener-like problems of non-interacting electrons in the Slater formalism for several $k \cdot p$ models representing Weyl and Dirac semimetals, we systematically include non-adiabatic corrections to a quantum limit of chiral charge pumping in these models. In this paper, we show that relative homotopy invariant [Sun et al., Phys. Rev. Lett. 121, 106402 (2018)] and Euler class invariant [Bouhon et al., Nat. Phys. 16, 1137 (2020)] non-trivially manifest in the non-adiabatic corrections to the quantum limit of chiral charge pumping. These corrections could affect conductivity channels connected with the presence of chiral anomaly. Moreover, we show that, for non-symmorphic systems, this contribution is sensitive to the direction of the applied magnetic field (in respect to the so-called non-symmorphic nodal loop), suggesting that the conjectured direction-selective chiral anomaly in non-symmorphic systems [Bzdu\v{s}ek et al., Nature (London) 538, 75 (2016)] could lead to a strongly anisotropic longitudinal magnetoresistance. The presented approach can be easily applied to other $k \cdot p$ or tight-binding models.
Full Proceeding Paper IN LABORATORY GENERATION AND MATURATION OF HUMAN MONOCYTE-DERIVED DENDRITIC CELLS FOR CANCER IMMUNOTHERAPY

Dendritic cells (DCs) play a critical role in the regulation of adaptive immune responses, furthermore they act as a bridge between the innate and the adaptive immune systems they have been ideal candidates for cell-based immunotherapy of cancers and infections in humans. The first reported trial using DCs in 1995, since they have been used in trials all over the world for several of indications, including cancer and human immunodeficiency virus infection. Generally, for in vitro experiments or for DCs vaccination monocyte-derived dendritic cells (moDCs) were generated from purified monocytes that isolated from peripheral blood by density gradient centrifugation. A variety of methods can be used for enrichment of monocytes for generation of clinical-grade DCs. Herein we summarized up to date understanding of systems and inputs used in procedures to differentiate DCs from blood monocytes in vitro.

Quantifying the effects of mixing state on aerosol optical properties

Abstract. Calculations of the aerosol direct effect on climate rely on simulated aerosol fields. The model representation of aerosol mixing state potentially introduces large uncertainties into these calculations, since the simulated aerosol optical properties are sensitive to mixing state. In this study, we systematically quantified the impact of aerosol mixing state on aerosol optical properties using an ensemble of 1800 aerosol populations from particle-resolved simulations as a basis for Mie calculations for optical properties. Assuming the aerosol to be internally mixed within prescribed size bins caused overestimations of aerosol absorptivity and underestimations of aerosol scattering. Together, these led to errors in the populations' single scattering albedo of up to −22.3 % with a median of −0.9 %. The mixing state metric χ proved useful in relating errors in the volume absorption coefficient, the volume scattering coefficient and the single scattering albedo to the degree of internally mixing of the aerosol, with larger errors being associated with more external mixtures. At the same time, a range of errors existed for any given value of χ. We attributed this range to the extent to which the internal mixture assumption distorted the particles' black carbon content and the refractive index of the particle coatings. Both can vary for populations with the same value of χ. These results are further evidence of the important yet complicated role of mixing state in calculating aerosol optical properties.
Profile of endoparasites in dairy cattle in the microregion of São João del-Rei,

The present study provides the first evaluation of the endoparasite profile in dairy cattle from the microregion of São João del-Rei, Minas Gerais, Brazil, including seasonal variations in parasitic infections. Fecal samples were collected directly from rectum of 123 dairy cows and 160 calves on 15 farms. These were kept in insulated boxes and sent for immediate analysis. Using eggs per gram of feces (EPG) we found the following prevalences: Strongyloidea 43.5%, Moniezia sp. 7.6% and both Strongyloides sp. and Trichuris spp. 2.2%, in dairy cows. In calves, the prevalence was Strongyloidea 50.9%, Moniezia sp. 5.6% and Strongyloides sp. 1.9%. The third-stage larvae recovered from coprocultures from cows and calves consisted mainly of Cooperia spp. , Haemonchus spp. and Ostertagia spp. EPG counts were significantly higher in calves. Regarding seasonality, the EPG counts and prevalence of Moniezia sp. tended to be higher in the dry period, whereas those of Strongyloidea were higher in the rainy season. Evidence suggests that parasite control and prophylaxis were inadequately managed on the farms studied here. The present parasitological profile correlates with those found by other similar studies, indicating that the main problem is still the inadequate management of parasite control and prophylaxis by farmers.
Does Dividend Policy Affect Earnings Management? Evidence From France

The objective of this paper is to examine the impact of the dividend policy on earnings management in France. Note that in recent years, research on the determinants of earnings management has multiplied. However, little work has really looked into this issue. The empirical research is based on a sample made up of French companies listed on the CAC All Tradable index for the period 2008-2015. The empirical results show that the dividend policy is a determinant of earnings management in the French context.
Effect of Hemostatic Agents on Shear Bond Strength of Orthodontic Eyelets Bonded with Conventional and Self-etch Adhesives

Statement of the Problem: The risk of debonding of the orthodontic eyelets due to blood contamination from the impacted tooth is a clinical problem that orthodontists face routinely. Purpose: This study aimed to assess the effect of hemostatic agents (Viscostat clear and Astringedent X) on shear bond strength (SBS) of orthodontic eyelets bonded with conventional (Transbond XT) and universal adhesive (GC-G Premio bond) adhesives. Materials and Method: In this experimental study, 84 freshly extracted bovine lower incisors were randomly divided into 7 groups namely TBXT, Blood, SEP, VISCO + TBXT, VISCO + SEP, ASTX + TBXT, and ASTX + SEP groups. In the TBXT group, teeth were etched with phosphoric acid gel, and then, the Transbond XT primer was applied and eyelets were bonded with Transbond XT. In the blood group, first, contamination with blood was done followed by the same procedure as TBXT. In other groups, the teeth were etched with phosphoric acid and based on their group allocation, Transbond XT primer (in TBXT groups), GC-G Premio Bond (in SEP groups), ViscoStat Clear gel (in VISCO groups), or Astringedent X (in ASTX groups) were applied. The SBS was measured for each group and the adhesive remnant index (ARI) was determined. Results: The mean SBS was 20.79 MPa in VISCO+SEP group, 19.2 MPa in the TBXT group, 16.06 MPa in the SEP group, 15.43 MPa in VISCO+TBXT group, 9.39 MPa in AST-X+TBXT group, and 1.62 MPa in the blood group. The SBS of ASTX+SEP, blood and TBXT+ASTX groups had significant differences from the SBS of the control group (p< 0.05). The ARI score of 0 had the highest frequency in the blood group. Conclusion: Due to the high coagulative effect of Astringedent X and acceptable SBS of Astringedent X in combination with GC-G Premio bond, this combination can be recommended for exposure of impacted teeth that are at high risk of blood contamination.
Resource and Power Management for In-Band D2D Communications

— Device-to-device (D2D) communications signiﬁcantly increase the ﬂexibility and capacity of a cellular network, where user equipments (UEs) are capable of directly conversing with each other without the relay by a base station (BS) . For in-band D2D communications, D2D pairs share the spectrum resources allocated to cellular UEs (CUEs) , which are the UEs in contact with the BS or with other devices through the BS. However, resource sharing would cause mutual signal interference between CUEs and D2D pairs. Consequently, how to efﬁciently allocate resources to CUEs and D2D pairs and also decide appropriate transmitted power for them is critical. In the chapter, we provide a comprehensive survey of resource and power management schemes for in-band D2D communications, and our discussion contains four parts. First, we give an overview of D2D communications, including their architecture, control policy, and communication mode. Then, we present the system model, which covers the network model, the estimation of channel quality, and the problem formulation for D2D resource and power management. After that, we elaborate on the existing management schemes, which are classiﬁed into matching-based, game-based, coloring-based, and other schemes. Finally, some research directions and challenges will be also addressed in this chapter.

ORGANIZATIONAL AMBIDEXTERITY WITHIN SUPPLY CHAIN MANAGEMENT: A SCOPING REVIEW

Background: Organizational ambidexterity is an emerging concept and it permeates too many functional domains in the discussion of organizational performance. The importance of understanding this concept motivates researchers to explore organizational ambidexterity as internal and external capabilities in the context of supply chain. Despite its importance in building oriented capabilities to organizations, little information is known about organizational ambidexterity in supply chain context. The objective of this review is to produce a comprehensive mapping of themes related to organizational ambidexterity studies in supply chain research, particularly in improving firm performance. Method: A scoping review of the literature was conducted using Web of Science (WoS), Scopus and EconBiz databases to identify what is the nature of published scientific literature on this topic and what are the emerging themes of organizational ambidexterity in relation to supply chain studies. Result: This study found three main themes and eleven sub-themes in relation to inter-organization ambidexterity in the supply chain context. The main themes include learning process, outcome and leadership. The review indicates that most of the studies are conducted in understanding learning process. Conclusion: The management of supply chain has a positive association with organizational ambidexterity. Supply chain operations involve selection, development, and implementation of new process(es) or technology (exploitation) - the outcome of a prior search procedure (exploration), which has been described as a sequential approach to exploration and exploitation and both processes are important especially in a dynamic environment. The findings from this scoping review indicate the importance of developing and managing a supply chain that supports exploration and exploitation practices. Therefore, managers should understand that maximizing a firm's current skills is critical to profitability and market share. While continuous refinement of existing knowledge is important, it is the generation and application of new knowledge that leads to increased value (profitability) and competitive advantage. Organizational ambidexterity within supply chain management provides significant benefits to big firms in improving their long-term efficiency. This offers avenue for future research to compare the effect of organizational ambidexterity in small firm.
Simultaneous estimation for the analysis of Paracetamol and Domperidone in tablet formulations by RP-HPLC method

A simple, fast, precise and accurate reverse phase high pressure liquid chromatographic method was developed for simultaneous estimation of paracetamol and domperidone from tablet by reverse phase waters C 18 column (250 x 4.6, mm, 5µm) . The sample was analyzed using Sodium Phosphate Buffer (Na 2 HPO 4 +NaH 2 PO 4 ): Acetonitrile in the ratio of 60:40 v/v ( pH adjusted to 7.5±0.1 with orthophosphoric acid) as mobile phase at a flow rate of 1.5ml/min & detection at 254 nm. The retention time for paracetamol & domperidone was found to be 2.1 & 8.5 min respectively. The validation of the proposed method was also carried out. The method was found to be linear (R 2 0.994 for paracetamol& R 2 0.997 for domperidone), precise (%RSD 0.98 for paracetamol & for domperidone 0.59) & selective. Due to its simplicity & accuracy, this method can be used for estimation of combination of these drugs in tablets dosage form.
Remote Online Teaching (ROT) in response to COVID‑19 pandemic: Exploring instructors’ experience

Background: Due to COVID‑19 pandemic, the whole world has experienced a rapid, mass university closure and a forced transition to online teaching to minimise disruptions to the academic year. The quick transition from in‑person to online teaching is presumed to be a challenging endeavour for many novice online instructors, and it is a ‘grand experiment’ that needs to be explored. Purpose and Research question: The aim of this research was to explore the Maldivian instructors’ experience of the COVID‑19 forced transitioning to remote online teaching. The research was guided by five central questions intended to gauge information focusing on teaching and learning and assessment strategies, support received, challenges and concerns, students’ reactions to the new learning experience, and recommendations from the instructors. Methodology: The study followed a qualitative multiple‑case study approach exploring the emergency remote online teaching experience of 7 instructors from three different higher education institutions that adopted a remote online learning strategy to allow educational continuity. Participants were selected through purposive convenience and snowball sampling method. The source of data for this research was a completed semi‑structured interview questionnaire and a phone interview conducted to confirm the information provided when deemed necessary. Manual thematic coding was applied to analyse open responses, and precoded aspects adopted from literature were analysed for its absence or presence in each of the cases. Cross and within case and institution analysis was performed to enable a coherent discussion. Findings: The findings of the study revealed that many instructors adopted a variety of strategies fit for an emergency online learning context and the main form of support was focused on technology integration rather than online pedagogy. The mains concerns identified related to student disengagement, instructor and student readiness and scepticism around online teaching influenced by traditional pedagogy. Conclusion and recommendations: Going forward, online teaching has to be carefully planned, systematically designed, to be effective. Instructors need to be supported to reformulate their teaching philosophy and develop competencies necessary for online teaching.
Silybum marianum seeds protected biochemical and oxidative stress markers in ethanol-induced toxicity of Wistar rat

In the present study, an attempt was made to evaluate the potential activity of Silybum marianum seeds infused solution (SMI) against ethanol (Eth) toxicity of Wistar rat liver and kidneys. Thirty six males (control, SMI positive control (200 mg/kg b.w./day), the Eth1 (01 g/kg b.w./day), the Eth2 (02 g/kg b.w./day), the Eth1+SMI and the Eth2+SMI) were orally administered for six successive weeks to measure serum biochemical parameters as well as hepatic and renal malondialdehyde (MDA), glutathione (GSH) and glutathione peroxidase (GPx) levels. According to the results, the Eth1+SMI and the Eth2+SMI alleviated ethanol-induced increased levels of ALT, AST, ALP, total cholesterol, triglycerides, LDL, urea, creatinine and MDA. Furthermore, the co-administration of SMI has maintained hepatic and renal GSH concentration and GPx activity close to that of the control. The SMI has alleviated ethanol-induced toxicity via the improvement of hepatic and renal markers.
IMPROVED SOCIAL SPIDER ALGORITHM FOR MINIMIZING MOLECULAR POTENTIAL ENERGY FUNCTION

: The social spider algorithm (SSA) is a new heuristic algorithm created on spider behaviors to solve continuous optimization problems. In this study, SSA is used in order to minimize a simplified model of the energy function of the molecule. The Molecular potential energy function problem is one of the most important real-life problems. The Molecular potential energy function problem attempts to predict the 3D structure of a protein. SSA is developed by various techniques (Crossover-mutation and G best convergence-silent spider techniques) and SSA is called Improved SSA (ISSA). By these techniques, the exploration and exploitation capabilities of SSA in the continuous search space are improved. The general performances of SSA and ISSA are tested on low-scaled and large-scaled thirteen benchmark functions and obtained results are compared with each other. Wilcoxon signed-rank test is applied to SSA and ISSA results. Then, the general performance of the SSA and ISSA is tested on a simplified model of the molecule for different dimensions. Also, the performance of the ISSA is compared to various state-of-art algorithms in the literature. The results showed the superiority of the performance of ISSA.
