description: Many areas of science and engineering encounter data defined on spherical manifolds. Modelling and analysis of spherical data often necessitates spherical harmonic transforms, at high degrees, and increasingly requires efficient computation of gradients for machine learning or other differentiable programming tasks. We develop novel algorithmic structures for accelerated and differentiable computation of generalised Fourier transforms on the sphere $\mathbb{S}^2$ and rotation group $\text{SO}(3)$, i.e. spherical harmonic and Wigner transforms, respectively. We present a recursive algorithm for the calculation of Wigner $d$-functions that is both stable to high harmonic degrees and extremely parallelisable. By tightly coupling this with separable spherical transforms, we obtain algorithms that exhibit an extremely parallelisable structure that is well-suited for the high throughput computing of modern hardware accelerators (e.g. GPUs). We also develop a hybrid automatic and manual differentiation approach so that gradients can be computed efficiently. Our algorithms are implemented within the JAX differentiable programming framework in the S2FFT software code. Numerous samplings of the sphere are supported, including equiangular and HEALPix sampling. Computational errors are at the order of machine precision for spherical samplings that admit a sampling theorem. When benchmarked against alternative C codes we observe up to a 400-fold acceleration. Furthermore, when distributing over multiple GPUs we achieve very close to optimal linear scaling with increasing number of GPUs due to the highly parallelised and balanced nature of our algorithms. Provided access to sufficiently many GPUs our transforms thus exhibit an unprecedented effective linear time complexity.

description: Without any doubt the young technology of additive manufacturing, including 2D and 3D printing, has been changing the world. A wide spectrum of objects in medical and pharmaceutical field can already be successfully printed. This ranges from a detailed figure in the micrometer regime to a full size residential house unit made from concrete [Sakin et al., 2017; Doherty et al., 2020]. In the pharmaceutical sector, additive manufacturing offers the option of medication customization [Pravin et al., 2018]. Integrating this new technology has several advantages over the current, well-established but outdated “one-size-fits-all” approach. Besides avoiding medication errors, printing tailored oral dosage forms is financially attractive for small scale on-demand production [Awad et al., 2018]. The development of dosage forms, production of sample batches and modification of samples can be done with little effort compared to generic powder-pressed pills which require heavy pharmaceutical machinery [Awad et al., 2018; Dachtler et al., 2020]. To further progress and to create the legal framework for the approval of additively manufactured drugs it requires a paradigm change of stakeholders who have the power to make decisions and changes [Horst et al., 2019].

description: The semi-empirical initial-final mass relation (IFMR) connects spectroscopically analyzed white dwarfs in star clusters to the initial masses of the stars that formed them. Most current stellar evolution models, however, predict that stars will evolve to white dwarfs $\sim$0.1 M$_\odot$ less massive than that found in the IFMR. We first look at how varying theoretical mass-loss rates, third dredge-up efficiencies, and convective-core overshoot may help explain the differences between models and observations. These parameters play an important role at the lowest masses (M$_{\rm initial}$ $

description: In December 2019, a series of pneumonia of unknown cause emerged in Wuhan, China, which developed into a global pandemic with more than 200 million cases and 4 million deaths worldwide as of August 2021. The enveloped RNA betacoronavirus which was found to cause the pandemic was named severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). Academia and industry started with non-clinical and clinical development of several SARS-CoV-2 vaccine candidates immediately and results were achieved enormously fast. As an example, BioNTech and Pfizer got their joint SARS-CoV-2 vaccine approved less than eight months after trials started, while under normal circumstances vaccine development takes up to 10 – 15 years. In the case of the SARS-CoV-2 vaccine the extremely fast turnaround time from start of clinical trials to approval of the first vaccine candidates was driven by the urgent medical need and made possible by the mobilisation of enormous financial resources from the private and public sectors, as well as manpower and effort and the willingness of regulators to speed up timelines and approval processes. Looking at the extremely fast and successful development of several SARS-CoV-2 vaccine candidates, it is difficult to understand from a layman’s perspective why for others diseases like Human Immunodeficiency Virus/ Acquired Immunodeficiency Syndrome (HIV/AIDS) and tuberculosis (TB), which are among the top ten causes of death worldwide, development of effective vaccines takes so long. More than 30 years after HIV has been discovered, there is still no vaccine available for prevention of HIV infection. Development of several vaccine candidates has failed in clinical trials. The difficulties stem in large part from HIV’s unusual characteristics of replicating and mutating rapidly and high sequence diversity, its ability of immune system evasion and the creation of a persistent viral reservoir within the host. Development of the novel TB vaccine candidate VPM1002, which is designed to be a safe and effective vaccine for prevention of TB infection and TB recurrence, is an example of classical vaccine development. VPM1002 was invented in Germany, went through successful non-clinical development and is currently being tested in phase III clinical trial. The achievements during the last year fast development of SARS-CoV-2 vaccines during the last year have proven that in case of a pandemic situation and an urgent medical need, fast vaccine development is possible. The achievements were reached with high financial commitment and regulators have shown willingness and engagement to accelerate timelines for review and approval processes. It would be desirable if further vaccine developments could benefit from these efforts.

description: Poorly separable liquid/liquid mixtures often pose a major challenge in pharmaceutical extraction. In particular, compounds containing a low difference of density are difficult to separate using mixer-settler setups. The Zaiput device can prove an advantage over present liquid/liquid extractors. The research work involves characterizing the Zaiput apparatus for liquid/liquid extraction of pharmaceutical compounds with the model solvent system toluene-water. The extraction efficiency was investigated for a solvent mixture containing toluene-acetone-water residence times. To evaluate the separation success, the outlet’s concentrations are measured via IR spectroscopy.

description: We describe numerical techniques used in the construction of our 4th order evolution for the full Einstein equations, and assess the accuracy of representative solutions. The code is based on a null gauge with a quasi-spherical radial coordinate, and simulates the interaction of a single black hole with gravitational radiation. Techniques used include spherical harmonic representations, convolution spline interpolation and filtering, and an RK4 "method of lines" evolution. For sample initial data of "intermediate" size (gravitational field with 19% of the black hole mass), the code is accurate to 1 part in 10^5, until null time z=55 when the coordinate condition breaks down.

description: The CMS collaboration reported a $\sim 3 \, \sigma$ (local) excess at $96\;$GeV in the search for light Higgs-boson decaying into two photons. This mass coincides with a $\sim 2 \, \sigma$ (local) excess in the $b\bar b$ final state at LEP. We show an interpretation of these possible signals as the lightest Higgs boson in the 2 Higgs Doublet Model with an additional complex Higgs singlet (2HDMS). The interpretation is in agreement with all experimental and theoretical constraints. We concentrate on the 2HDMS type II, which resembles the Higgs and Yukawa structure of the Next-to Minimal Supersymmetric Standard Model. We discuss the experimental prospects for constraining our explanation at future $e^+e^-$ colliders, with concrete analyses based on the ILC prospects.

description: Mixing is a crucial parameter for a wide range of processes in bio-/chemical engineering. In multiphase flows, the aim is a high and uniform mixing effect throughout the reaction volume without negative effects on the discrete phase. These are usually caused by the hydromechanical stress exerted by the mixing element. The present study introduces a novel reactor concept to overcome the use of fast rotating, locally acting mixing elements common in stirred tank reactors. Therefore, the reactor is designed of a flat, horizontally mounted cylinder, which enables mixing of the enclosed volume by its rotation around the central axis. To evaluate the mixing performance, a colorimetric method for mixing time determination is presented and the spatial evolution of mixing kinetics visualized. In addition, the method reveals the dependencies of the mixing time on the rotational speed and filling volume.

description: In this paper we propose a consensus group decision making scheme under model uncertainty consisting of an iterative two-stage procedure and based on the concept of Fréchet barycenter. Each step consists of two stages: the agents first update their position in the opinion metric space by a local barycenter characterized by the agents' immediate interactions and then a moderator makes a proposal in terms of a global barycenter, checking for consensus at each step. In cases of large heterogeneous groups the procedure can be complemented by an auxiliary initial homogenization step, consisting of a clustering procedure in opinion space, leading to large homogeneous groups for which the aforementioned procedure will be applied.
 The scheme is illustrated in examples motivated from environmental economics.

description: Encapsulation of clinically relevant cells, such as multipotent stromal cells (MSCs), in three-dimensional (3D) core-shell alginate structures is a promising method for the treatment of various diseases as well as drug testing and development. By utilizing the alginate capsules, drugs and active substances can be delivered specifically to the desired place within the patients’ body. The aim of this work was to investigate the effect of cryopreservation on the integrity of cell-free coaxial alginate capsules after thawing using slow freezing to ensure their long-term storage. Alginate capsules were produced by electro-spraying and cryopreserved using different cryoprotective agents (CPAs), incubation time and thawing temperature. The results suggest that the capsules loaded with 10% (v/v) dimethyl sulfoxide (DMSO) and 0.3 M sucrose and using high thawing rates demonstrated a beneficial effect on the integrity of capsules, as compared to 10% (v/v) DMSO alone and applying low thawing rates. This study is a further development towards the application of cryopreservation for long-term storage and the emerging cell-based medicine.

description: Spherical agglomeration (SA) is a key crystal shape modification technique commonly used to improve processability and physical properties of active pharmaceutical ingredients (APIs), such as flowability and dissolution. SA involves the introduction of a bridging liquid in the form of droplets into a suspension of API crystals. A novel approach was successfully implemented in this study by adopting a membrane emulsification (ME) system to control the size of bridging liquid droplets and spherical agglomerates. The study investigated ways to achieve the critical quality attributes of the spherical agglomerates by varying operating conditions and design parameters, including mixing rate, bridging liquid injection rate and membrane pore diameter. Antisolvent crystallization of benzoic acid in ethanol (solvent) and water (antisolvent) in presence of toluene as a bridging liquid was used as a case study. Spherical agglomerates of benzoic acid with enhanced quality attributes and mean size of 300 μm were obtained using a membrane pore size of 18 μm, a bridging liquid flow rate of 0.025 mL/min and mixing rate in the range of 800 RPM and 1000 RPM.

description: Third-party package usage has become a common practice in contemporary software development. Developers often face different challenges, including choosing the right libraries, installing errors, discrepancies, setting up the environment, and building failures during software development. The risks of maintaining a third-party package are well known, but it is unclear how information from Stack Overflow (SO) can be useful. This paper performed an empirical study to explore npm co-usage in SO. From over 30,000 SO posts, we extracted 2,100 SO posts related to npm and matched them to 217,934 npm library packages. We find that, popular and highly used libraries are not discussed as often in SO. However, we can see that the accepted answers may prove useful, as we believe that the usage examples and executable commands could be reused for tool support.

We investigate the consequences when a small group of mutants using quantum strategies try to invade a classical ESS in a population engaged in symmetric bimatrix game of Prisoner's Dilemma. Secondly we show that in an asymmetric quantum game between two players an ESS pair can be made to appear or disappear by resorting to entangled or unentangled initial states used to play the game even when the strategy pair remains a Nash equilibrium in both forms of the game.

description: Let $A_1$ be the (first) Weyl algebra, and let $G$ be its automorphism group. We study the natural action of $G$ on the space of isomorphism classes of right ideals of $A_1$ (equivalently, of finitely generated rank 1 torsion-free right $A_1$-modules). We show that this space breaks up into a countable number of orbits each of which is a finite dimensional algebraic variety. Our results are strikingly similar to those for the commutative algebra of polynomials in two variables; however, we do not know of any general principle that would allow us to predict this in advance. As a key step in the proof, we obtain a new description of the bispectral involution of \cite{W1}. We also make some comments on the group $G$ from the viewpoint of Shafaravich's theory of infinite dimensional algebraic groups.

description: The question of the universality of the longitudinal peak conductivity at the integer quantum Hall transition is considered. For this purpose, a system of 2D Dirac fermions with random mass characterised by variance $g$ is proposed as a model which undergoes a quantum Hall transition. Whilst for some specific models the longitudinal peak conductivity $σ_{xx}$ was found to be universal (in agreement with the conjecture of Lee et al. as well as with some numerical work), we find that $σ_{xx}$ is reduced by a factor $(1+g/2π)^{-1}$, at least for small $g$. This provides some theoretical evidence for the non-universality of $σ_{xx}$, as observed in a number of experiments.

description: Tristructural-isotropic (TRISO) fuel is currently one of the most mature fuel types for candidate advanced reactor types, namely pebble bed reactors (PBRs). In PBRs, TRISO-fueled pebbles can be re-introduced into the core several times before reaching their target burnup. Non-destructive techniques capable of assaying ${}^{235}$U mass in the pebble are therefore needed for nuclear material control and accountability during fuel recirculation. In this work, we have developed a new boron-coated straw (BCS) based neutron multiplicity counter (NMC) to estimate ${}^{235}$U mass in each pebble. BCS detectors are chosen for their inherent high insensitivity to gamma rays that will enable their use to assay also irradiated pebbles and high neutron detection efficiency, comparable to ${}^{3}$He detectors. The BCS-based NMC that we have designed was built by Proportional Technologies, Inc. (PTI) Houston, TX. In this work, we report the system-level simulation of the BCS-based NMC and the straw-level charge collection simulation coupled with a custom software to tally the detected pulse integral from the list mode energy deposited. We have developed a high-fidelity model of the NMC to simulate the response of a single straw detector to a ${}^{252}$Cf source. The simulated die-away time, single neutron count rate, and double neutron count rate agree well with measured values, with a relative difference within $\pm$0.4\%. The simulated charge spectrum agrees well with the measured one in the case of a round straw. We plan to use the NMC to perform active and passive interrogation of fresh and spent fuel pebbles.

description: Pebble bed reactor (PBR) relying on TRISO-fueled pebbles is one of the most promising Gen-IV reactor designs because of intrinsic safety and thermal efficiency. Fuel pebbles flow through PBR's core and the identification of individual pebbles exiting the core will be beneficial to improve safeguards and fuel management. We propose a pebble identification method that is fast, accurate, robust, and applicable to PBRs containing hundreds of thousands of pebbles. The identification relies on the internal distribution of TRISO fuel particles, which is a unique feature of each pebble. We experimentally demonstrated that X-ray CT can extract the particle distribution with high accuracy. We then applied the algorithm to identify a single pebble in a data set of 100,000 pebbles achieving 100% identification accuracy in 90,000 tests with the presence of arbitrary rotations and measurement noises. The average time to identify one pebble is below 50 s, compatible with PBR operation.

description: In this study, a novel approach was developed for determining the density of compacts using ultraviolet–visible spectrophotometry. The assumption within this context was that a change in density affects the corresponding color information of the compact. From the obtained spectra of the visible range, the color information of the compact was calculated which turned out to be directly proportional to the density of the compact. In comparison, the obtained spectra were analyzed using partial least square regression. The results of this study showed that both methods could be used predicting the density of a compact from the corresponding visible spectrum at identical accuracy. In contrast to the partial least square regression, the correlation of the color information as a direct output parameter of the spectrophotometer with the density required no excessive data pre-processing. Subsequently, the easier and faster data processing of the color information over the partial least square regression, conceives using this novel approach as potential process analytical technology tool for implementation into a compression process e.g., tableting or roller compaction.

description: Inducing magnetic orders in a topological insulator (TI) to break its time reversal symmetry has been predicted to reveal many exotic topological quantum phenomena. The manipulation of magnetic orders in a TI layer can play a key role in harnessing these quantum phenomena towards technological applications. Here we fabricated a thin magnetic TI film on an antiferromagnetic (AFM) insulator Cr2O3 layer and found that the magnetic moments of the magnetic TI layer and the surface spins of the Cr2O3 layers favor interfacial AFM coupling. Field cooling studies show a crossover from negative to positive exchange bias clarifying the competition between the interfacial AFM coupling energy and the Zeeman energy in the AFM insulator layer. The interfacial exchange coupling also enhances the Curie temperature of the magnetic TI layer. The unique interfacial AFM alignment in magnetic TI on AFM insulator heterostructures opens a new route toward manipulating the interplay between topological states and magnetic orders in spin-engineered heterostructures, facilitating the exploration of proof-of-concept TI-based spintronic and electronic devices with multi-functionality and low power consumption.

description: With the more and more extensive application of blockchain, blockchain security has been widely concerned by the society and deeply studied by scholars. Moreover, the security of blockchain data directly affects the security of various applications of blockchain. In this survey, we perform a comprehensive classification and summary of the security of blockchain data. First, we present classification of blockchain data attacks. Subsequently, we present the attacks and defenses of blockchain data in terms of privacy, availability, integrity and controllability. Data privacy attacks present data leakage or data obtained by attackers through analysis. Data availability attacks present abnormal or incorrect access to blockchain data. Data integrity attacks present blockchain data being tampered. Data controllability attacks present blockchain data accidentally manipulated by smart contract vulnerability. Finally, we present several important open research directions to identify follow-up studies in this area.

description: Coleoid cephalopods (squid, cuttlefish, octopus) have the largest nervous system among invertebrates that together with many lineage-specific morphological traits enables complex behaviors. The genomic basis underlying these innovations remains unknown. Using comparative and functional genomics in the model squid Euprymna scolopes, we reveal the unique genomic, topological, and regulatory organization of cephalopod genomes. We show that coleoid cephalopod genomes have been extensively restructured compared to other animals, leading to the emergence of hundreds of tightly linked and evolutionary unique gene clusters (microsyntenies). Such novel microsyntenies correspond to topological compartments with a distinct regulatory structure and contribute to complex expression patterns. In particular, we identify a set of microsyntenies associated with cephalopod innovations (MACIs) broadly enriched in cephalopod nervous system expression. We posit that the emergence of MACIs was instrumental to cephalopod nervous system evolution and propose that microsyntenic profiling will be central to understanding cephalopod innovations.

description: In many natural and artificial devices diffusive transport takes place in confined geometries with corrugated boundaries. Such boundaries cause both entropic and hydrodynamic effects, which have been studied only for the case of spherical particles. Here we experimentally investigate diffusion of particles of elongated shape confined into a corrugated quasi-two-dimensional channel. Elongated shape causes complex excluded-volume interactions between particle and channel walls which reduce the accessible configuration space and lead to novel entropic free energy effects. The extra rotational degree of freedom also gives rise to a complex diffusivity matrix that depends on both the particle location and its orientation. We further show how to extend the standard Fick-Jacobs theory to incorporate combined hydrodynamic and entropic effects, so as, for instance, to accurately predict experimentally measured mean first passage times along the channel. Our approach can be used as a generic method to describe translational diffusion of anisotropic particles in corrugated channels.

description: In situ tissue engineering requires to functionalize the surfaces of implants, to achieve better biocompatibility or to release pharmaceuticals. Often a burst release of such pharmaceuticals takes place and the surface functionality is gone rapidly. Casein-micelles (M-Cas) offer unique release capabilities for hydrophobic and hydrophilic substances. In this work, M-Cas were reconstructed and used as release system for curcumin as a model drug. Modified electrospun polycaprolactone (PCL)-fiber mats were coated with chitosan / tripolyphosphate nanoparticles (CS/TPP-NP) and functionalized with the reconstructed M-Cas. [1] CS/TPP-NPs and Na-caseinate (Cas) were used as blocking layer to slow down the release of curcumin loaded micelles. The layers were investigated by surface zeta-potential (ZP). The release of the curcumin from surfaces was possible and the blocking layers had a significant influence on the kinetics.

The Role of Energy and a New Approach to Gravitational Waves in General Relativity
Creators: name: Cooperstock, F. I.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The energy localization hypothesis of the author that energy is localized in non-vanishing regions of the energy-momentum tensor implies that gravitational waves do not carry energy in vacuum. If substantiated, this has significant implications for current research. Support for the hypothesis is provided by a re-examination of Eddington's classic calculation of energy loss by a spinning rod. It is emphasized that Eddington did not monitor the entire Tolman energy integral, concentrating solely upon the change of the 'kinetic' part of the energy . The 'quadrupole formula' is thus seen to measure the kinetic energy change. When the derivative of the missing stress-trace integral is computed, it is seen to cancel the Eddington term and hence the energy of the rod is conserved, in support of the localization hypothesis. The issue of initial and final states is addressed.

Adaptation to the Edge of Chaos in the Self-Adjusting Logistic Map

description: Self-adjusting, or adaptive systems have gathered much recent interest. We present a model for self-adjusting systems which treats the control parameters of the system as slowly varying, rather than constant. The dynamics of these parameters is governed by a low-pass filtered feedback from the dynamical variables of the system. We apply this model to the logistic map and examine the behavior of the control parameter. We find that the parameter leaves the chaotic regime. We observe a high probability of finding the parameter at the boundary between periodicity and chaos. We therefore find that this system exhibits adaptation to the edge of chaos.

description: We study the effects of the phonon-phonon coupling on the low-energy electric dipole response within a microscopic model based on an effective Skyrme interaction. The finite rank separable approach for the quasiparticle random phase approximation is used. Choosing as an example the isotopic chain of Calcium, we show the ability of the method to describe the low-energy $E1$ strength distribution. With one and the same set of parameters we describe available experimental data for $^{48}$Ca and predict the electric dipole strength function for $^{50}$Ca.
