description: Regular inspection and maintenance of infrastructure facilities are crucial to ensure their functionality and safety for users. However, current inspection methods are labor-intensive and can vary depending on the inspector. To improve this process, modern sensor systems and machine learning algorithms can be deployed to detect defects based on rapidly acquired data, resulting in lower downtime. A quality-controlled processing chain allows to provide hence informed uncertainty assessments to inspection operators. In this study, we present several Deeplab V3+ models optimized to predict corroded segments of the quay wall at JadeWeserPort, Germany, which is a dataset from the 3D HydroMapper research project. Our models achieve generally high accuracy in detecting this damage type. Therefore, we examine the use of a Region Growing-based weakly supervised approach to efficiently extend our model to other common types in the future. This approach achieves about 90 % of the results compared to corresponding fully supervised networks, of which a ResNet-50 variant peaks at 55.6 % Intersection-over-Union regarding the test set's corrosion class.

description: Facial expressions convey nonverbal cues which play an important role in interpersonal relations, and are widely used in behavior interpretation of emotions, cognitive science, and social interactions. In this paper we analyze different ways of representing geometric feature and present a fully automatic facial expression recognition (FER) system using salient geometric features. In geometric feature-based FER approach, the first important step is to initialize and track dense set of facial points as the expression evolves over time in consecutive frames. In the proposed system, facial points are initialized using elastic bunch graph matching (EBGM) algorithm and tracking is performed using Kanade-Lucas-Tomaci (KLT) tracker. We extract geometric features from point, line and triangle composed of tracking results of facial points. The most discriminative line and triangle features are extracted using feature selective multi-class AdaBoost with the help of extreme learning machine (ELM) classification. Finally the geometric features for FER are extracted from the boosted line, and triangles composed of facial points. The recognition accuracy using features from point, line and triangle are analyzed independently. The performance of the proposed FER system is evaluated on three different data sets: namely CK+, MMI and MUG facial expression data sets.

description: PSR B1706$-$44 is an energetic gamma-ray pulsar located inside supernova remnant (SNR) G343.1$-$2.3 and it powers a compact pulsar wind nebula (PWN) that shows torus and jet structure in X-rays. We present a radio study of the PWN using Australia Telescope Compact Array (ATCA) observations at 3, 6, 13, and 21\,cm. We found an overall arc-like morphology at 3 and 6\,cm, and the ``arc" shows two distinct peaks at 6\,cm. The radio emission is faint inside the X-ray PWN and only brightens beyond that. We develop a thick torus model with Doppler boosting effect to explain the radio PWN structure. The model suggests a bulk flow speed of $\sim 0.2c$, which could indicate significant deceleration of the flow from the X-ray emitting region. Our polarization result reveals a highly ordered toroidal $B$-field in the PWN. Its origin is unclear given that the supernova reverse shock should have interacted with the PWN. At a larger scale, the 13 and 21\,cm radio images detected a semi-circular rim and an east-west ridge of G343.1$-$2.3. We argue that the latter could possibly be a pulsar tail rather than a filament of the SNR, as supported by the flat radio spectrum and the alignment between the magnetic field and its elongation.

Development and validation of generic food packaging migration testing analytical methodology
Creators: name: Zhang, Nan

Year: 2022

description: Food packaging plays an important role in our daily life. Global regulatory agencies have established different food packaging regulations that mandate manufacturers to perform related analytical testing to ensure food safety. The rapid introduction of new materials and technologies to complex food packaging matrices brought great challenges for developing analytical testing procedures that can demonstrate regulation compliance. This study aimed to help food packaging manufacturers develop a battery of generic, fast, efficient, and cost-effective analytical methodologies for their routine food packaging analyses. The battery approach included a decision tree dependent non-targeted screening analyses and targeted quantitation analyses utilizing gas chromatography mass spectrometry (GC-MS) and liquid chromatography mass spectrometry (LC-MS) analytical techniques. Eight representative commercial food packaging samples intended for different applications were analyzed using the developed approach to exemplify its efficacy. Notable migrants from each packaging material such as plasticizers, slip additives, antioxidants, photoinitiators, and monomers were identified and discussed for their origins, mechanism of migration, and degradation pathways. Novel compounds such as tetramethyl bisphenol F and Weston 705 type migrants were reported for the first time in this research. Targeted method validation of 14 selected compounds was presented including linearity of calibration, limit of detection, limit of quantitation, spiking and recovery from food simulant matrices, accuracy, and precision. The identified compounds in this study can provide important references for food packaging manufacturers who need to identify migrants from their products. The developed approach also can be used in their routine analytical and quality control procedures design and development.

description: We review existing manifestations and prospects for ferroelectricity in electronically and optically active carbon-based materials. The focus point is the proposal for the electronic ferroelectricity in conjugated polymers from the family of substituted polyacetylenes. The attractive feature of synthetic organic ferroelectrics is a very high polarizability coming from redistribution of the electronic density, rather than from conventional displacements of ions. Next fortunate peculiarity is the symmetry determined predictable design of perspective materials. The macroscopic electric polarization follows ultimately from combination of two types of a microscopic symmetry breaking which are ubiquitous to qusi-1D electronic systems. The state supports anomalous quasi-particles - microscopic solitons, carrying non-integer electric charges, which here play the role of nano-scale nucleus of ferroelectric domain walls. Their spectroscopic features in optics can interfere with low-frequency ferroelectric repolarization providing new accesses and applications. In addition to already existing electronic ferroelectricity in organic crystals and donor-acceptor chains, we point to a class of conducting polymers and may be also to nano-ribbons of the graphene where such a state can be found. These proposals may lead to potential applications in modern intensive searches of carbon ferroelectrics.

Multiband thermal transport in the iron-based superconductor Ba1 xKxFe2As2

description: We present results of precise measurements of the thermal and electrical transport in the optimally- and over-doped Ba1-xKxFe2As2 single crystals (x = 0.35, 0.55, 0.88) and compare them to the previously reported data on Ba(Fe1-yCoy)2As2. A contraction of the electron pocket is observed upon substitution potassium for barium, but even at the extreme doping (x = 0.88) there is still a noticeable contribution from negative charge carriers to the electronic transport. The size of the electron pocket in all K-doped samples is small enough to cause a significant enhancement of the respective Hall-Lorenz number. Another observed characteristic is the emergence of a maximum in the transverse thermal conductivity below the superconducting critical temperature of the optimally- (x = 0.35) and slightly over-doped (x = 0.55) samples. The evolution of this anomaly from the optimally electron-doped Ba(Fe0.94Co0.06)2As2 to hole-overdoped Ba0.45K0.55Fe2As2 suggests formation of a uniform superconducting gap on the electron pocket in the former and regions of a depressed gap on the hole-pocket in the latter.

description: In this paper, we report the multiwavelength observations of an erupting prominence and the associated CME on 13 May 2013. The event occurs behind the western limb in the field of view of SDO/AIA. The prominence is supported by a highly twisted magnetic flux rope and shows rapid rotation in the counterclockwise direction during the rising motion. The rotation of the prominence lasts for $\sim$47 minutes. The average period, angular speed, and linear speed are $\sim$806 s, $\sim$0.46 rad min$^{-1}$, and $\sim$355 km s$^{-1}$, respectively. The total twist angle reaches $\sim$7$π$, which is considerably larger than the threshold for kink instability. Writhing motion during 17:42$-$17:46 UT is clearly observed by SWAP in 174 Å and EUVI on board the behind STEREO spacecraft in 304 Å after reaching an apparent height of $\sim$405\,Mm. Therefore, the prominence eruption is most probably triggered by kink instability. A pair of conjugate flare ribbons and post-flare loops are created and observed by STA/EUVI. The onset time of writhing motion is consistent with the commencement of the impulsive phase of the related flare. The 3D morphology and positions of the associated CME are derived using the graduated cylindrical shell (GCS) modeling. The kinetic evolution of the reconstructed CME is divided into a slow-rise phase ($\sim$330 km s$^{-1}$) and a fast-rise phase ($\sim$1005 km s$^{-1}$) by the writhing motion. The edge-on angular width of the CME is a constant (60$^{\circ}$), while the face-on angular width increases from 96$^{\circ}$ to 114$^{\circ}$, indicating a lateral expansion. The latitude of the CME source region decreases slightly from $\sim$18$^{\circ}$ to $\sim$13$^{\circ}$, implying an equatorward deflection during propagation.

We demonstrate a duality between fracton topological order and interacting spin systems with symmetries along extensive, lower-dimensional subsystems, which may be used to systematically search for and characterize fracton topological phases. Commutative algebra and elementary algebraic geometry provide an effective mathematical toolset for our results. Our work paves the way for identifying possible material realizations of fracton topological phases.

Silicon Solar Cell Improvements

description: 29th European Photovoltaic Solar Energy Conference and Exhibition; 507-512
description: This paper describes a viable path for the mass production of Si solar cells that lead to lower cost for
PV electrical energy. Systems and modules having solar cells with plated metal contacts benefit from both, a higher
solar cell performance as well as significantly reduced consumable cost.
As most advances in industrial solar cell production over the past decades the introduction of plating technology
benefits from significant equipment and material improvements. In parallel this road offers to shift the limits with
respect to achievable solar cell efficiency by inherent advantages such as the possibility to form narrower metal
contacts of excellent conductivity at low cost and the possibility to contact moderately doped Si areas.
Efficiency improvements depend on the degree that other processing steps are adapted to the new degree of freedom
in optimization offered by plated contact formation. Efficiency improvement is experimentally demonstrated.
Equipment solutions and cost aspects are addressed. Besides good reliability and adhesion of the plated contacts we
show efficiency potential exceeding 21% for PERC-type Si solar cells.

description: We present a systematic characterization of multi-wavelength emission from blazar PKS 1510-089 using well-sampled data at infrared(IR)-optical, X-ray and $γ$-ray energies. The resulting flux distributions, except at X-rays, show two distinct lognormal profiles corresponding to a high and a low flux level. The dispersions exhibit energy dependent behavior except for the LAT $γ$-ray and optical B-band. During the low level flux states, it is higher towards the peak of the spectral energy distribution, with $γ$-ray being intrinsically more variable followed by IR and then optical, consistent with mainly being a result of varying bulk Lorentz factor. On the other hand, the dispersions during the high state are similar in all bands expect optical B-band, where thermal emission still dominates. The centers of distributions are a factor of $\sim 4$ apart, consistent with anticipation from studies of extragalactic $γ$-ray background with the high state showing a relatively harder mean spectral index compared to the low state.

description: As the constituents of a flock are polar, one expects a fore-aft asymmetry in their interactions. We show here that the resulting antisymmetric part of the "exchange coupling" between a bird and its neighbours, if large enough, destabilizes the flock through spontaneous turning of the birds. The same asymmetry also yields a natural mechanism for a difference between the speed of advection of information along the flock and the speed of the flock itself. We show that the absence of detailed balance, and not merely the breaking of Galilean invariance, is responsible for this difference. We delineate the conditions on parameters and wavenumber for the existence of the turning instability. Lastly we present an alternative perspective based on flow-alignment effects in an active liquid crystal with turning inertia in contact with a momentum sink.

description: Accurate and extensive atomic data are essential for spectroscopic analyses of stellar atmospheres and other astronomical objects. We present energy levels, lifetimes, and transition probabilities for neutral nitrogen, the sixth most abundant element in the cosmos. The calculations employ the fully relativistic multiconfiguration Dirac-Hartree-Fock and relativistic configuration interaction methods, and span the 103 lowest states up to and including 2s$^2$2p$^2$5s. Our theoretical energies are in excellent agreement with the experimental data, with an average relative difference of 0.07%. In addition, our transition probabilities are in good agreement with available experimental and theoretical data. We further verify the agreement of our data with experimental results via a re-analysis of the solar nitrogen abundance, with the results from the Babushkin and Coulomb gauges consistent to 2% or 0.01 dex. We estimated the uncertainties of the computed transition data based on a statistical analysis of the differences between the transition rates in Babushkin and Coulomb gauges. Out of the 1701 computed electric dipole transitions in this work, 83 (536) are associated with uncertainties less than 5% (10%).

description: In this work a novel method for improving multicrystalline ingot properties is presented. The method
consists of using a specially designed masteralloy, Elkem Masteralloy for multi ingots (EMMA™), to the charge.
Results obtained on G1 and G5 scale show reduced inclusion content as revealed by IR-imaging. Further
investigations with FEG-SEM identified that these inclusions were mainly silicon nitrides. Solar cell efficiencies of
the G1 ingots showed a clear enhancement of the efficiency in the bottom of the ingots (height < 25 mm), in the socalled
red-zone. This effect seems to be linked to the EMMA™ addition, since the effect was more pronounced with
increase in EMMA™ content to the ingots. It is also seen on minority carrier lifetime images from G5 ingots with
increased EMMA™ addition that the red-zone is reduced and bulk lifetime enhanced. Solar cell efficiencies obtained
on G5 ingots showed up to 0.3% increase in average cell efficiency. Distribution of cell efficiency for G5 ingots
produced and processed in industry gave higher fraction of cells in higher efficiency segments and correspondingly
lower fraction in lower efficiency segments.

description: In this paper we study a proportionate flow shop of batching machines with release dates and a fixed number m≥2 of machines. The scheduling problem has so far barely received any attention in the literature, but recently its importance has increased significantly, due to applications in the industrial scaling of modern bio-medicine production processes. We show that for any fixed number of machines, the makespan and the sum of completion times can be minimized in polynomial time. Furthermore, we show that the obtained algorithm can also be used to minimize the weighted total completion time, maximum lateness, total tardiness and (weighted) number of late jobs in polynomial time if all release dates are 0. Previously, polynomial time algorithms have only been known for two machines.

description: Diffusion at solid-liquid interfaces is crucial in many technological and biophysical processes. Although its behavior seems deceivingly simple, recent studies showing passive superdiffusive transport suggest diffusion on surfaces may hide rich complexities. In particular, bulk-mediated diffusion occurs when molecules are transiently released from the surface to perform three-dimensional excursions into the liquid bulk. This phenomenon bears the dichotomy where a molecule always return to the surface but the mean jump length is infinite. Such behavior is associated with a breakdown of the central limit theorem and weak ergodicity breaking. Here, we use single-particle tracking to study the statistics of bulk-mediated diffusion on a supported lipid bilayer. We find that the time-averaged mean square displacement (MSD) of individual trajectories, the archetypal measure in diffusion processes, does not converge to the ensemble MSD but it remains a random variable, even in the long observation-time limit. The distribution of time averages is shown to agree with a Lévy flight model. Our results also unravel intriguing anomalies in the statistics of displacements. The time averaged MSD is shown to depend on experimental time and investigations of fractional moments show a scaling $\langle |r(t)|^q\rangle \sim t^{qν(q)}$ with non-linear exponents, i.e. $ν(q)\neq\textrm{const}$. This type of behavior is termed strong anomalous diffusion and is rare among experimental observations.

description: We study the instability of the superconducting state in a mesoscopic geometry for the low pinning material Mo$_3$Ge characterized by a large Ginzburg-Landau parameter. We observe that in the current driven switching to the normal state from a nonlinear region of the Abrikosov flux flow, the mean critical vortex velocity reaches a limiting maximum velocity as a function of the applied magnetic field. Based on time dependent Ginzburg-Landau simulations we argue that the observed behavior is due to the high velocity vortex dynamics confined on a mesoscopic scale. We build up a general phase diagram which includes all possible dynamic configurations of Abrikosov lattice in a mesoscopic superconductor.

featuring a laser patterned front and Ni/Cu contacts. At first, the laser induced recombination for different n+/n/n+
structures is quantified, showing that its dimensions depend strongly on the “high-low” junction depth. Selective laser
doping is evaluated as an alternative solution for the patterning of the metal contacts. Different thermal sequences are
tested to anneal the laser-induced defects for both laser ablated and laser doped cells. An absolute increase of jsc of
0.5 mA/cm2 for the laser doped cells is demonstrated, with conversion efficiencies over 21%.

description: To produce more cost-effective multicrystalline silicon wafers, increasing the ingot size represents an
important direction. The potential benefits from having bigger ingot include higher volume to surface area ratio to
reduce contamination from crucibles, higher output per furnace and more homogeneous crystalline structure. However,
to evaluate the wafers’ quality by processing the wafers into cells is a very time consuming process and the data tracking
is complicated and difficult. With recently developed in-line wafer photoluminescence (PL) device, it had been made
possible that a controlled PL measurement of the as-sawed wafers be assembled to reflect the ingot growth history. It
was found that by upgrading from G5 to G7, both the grain boundary/dislocation cluster area and the contamination

description: We study the propagation properties and light-matter interactions of the focused doughnut pulses, broadband, single-cycle electromagnetic perturbations of toroidal topology first described by Hellwarth and Nouchi in 1996. We show how focused doughnuts are reflected and refracted at planar metallic and vacuum-dielectric interfaces leading to complex distortions of the field structure. We also identify the conditions under which these toroidal pulses excite dominant dynamic toroidal dipoles in spherical dielectric particles.

description: In this paper we study in detail the effect of the rotational alignment between a hexagonal boron nitride (hBN) slab and the graphene layers in the vertical current of a a graphene-hBN-graphene device. We show how for small rotational angles, the transference of momentum by the hBN crystal lattice leads to multiple peaks in the I-V curve of the device, giving origin to multiple regions displaying negative differential conductance. We also study the effect of scattering by phonons in the vertical current an see how the opening up of inelastic tunneling events allowed by spontaneous emission of optical phonons leads to sharp peaks in the second derivative of the current.

description: Vera C. Rubin Observatory, through the Legacy Survey of Space and Time (LSST), will allow us to derive a panchromatic view of variability in young stellar objects (YSOs) across all relevant timescales. Indeed, both short-term variability (on timescales of hours to days) and long-term variability (months to years), predominantly driven by the dynamics of accretion processes in disk-hosting YSOs, can be explored by taking advantage of the multi-band filters option available in Rubin LSST, in particular the $u,g,r,i$ filters that enable us to discriminate between photospheric stellar properties and accretion signatures. The homogeneity and depth of sky coverage that will be achieved with LSST will provide us with a unique opportunity to characterize the time evolution of disk accretion as a function of age and varying environmental conditions (e.g. field crowdedness, massive neighbors, metallicity), by targeting different star-forming regions. In this contribution to the Rubin LSST Survey Strategy Focus Issue, we discuss how implementing a dense observing cadence to explore short-term variability in YSOs represents a key complementary effort to the Wide-Fast-Deep observing mode that will be used to survey the sky over the full duration of the main survey ($\approx$10 years). The combination of these two modes will be vital to investigate the connection between the inner disk dynamics and longer-term eruptive variability behaviors, such as those observed on EXor objects.

Orientational ordering of confined hard rods: the effect of shape anisotropy on surface ordering and capillary nematization

description: We examine the ordering properties of rectangular hard rods with length L and diameter D at a single planar wall and between two parallel hard walls using the second-virial density functional theory. The theory is implemented in the three-state Zwanzig approximation, where only three mutually perpendicular directions are allowed for the orientations of hard rods. The effect of varying shape anisotropy is examined at L/D=10, 15 and 20. In contact with a single hard wall, the density profiles show planar ordering, damped oscillatory behavior, and wall induced surface ordering transition below the coexisting isotropic density of bulk isotropic-nematic (I-N) phase transition. Upon approaching the coexisting isotropic density, the thickness of nematic film diverges logarithmically, i.e. the nematic wetting is complete for any shape anisotropy. In the case of confinement between two parallel hard walls, it is found that the continuous surface ordering transition depends strongly on the distance between confining walls (H) for HL. The minimal density at which a surface ordering transition can be realized is located at around H~2D for all studied shape anisotropies due to the strong interference effect between the two hard walls. The first order I-N phase transition of the bulk system becomes surface ordered isotropic (IB)-capillary nematic (NB) phase transition in the slit pore. This first order IB-NB transition weakens with decreasing pore width and terminates in a critical point for all studied shape anisotropies.

description: During the recent year, it has been proven that silicon heterojunction (Si-HJT) solar cells can achieve
efficiencies close to 25 % using simple cell structure. However, most of these record cells have been achieved at the
R&D scale and only few companies are producing Si-HJT cells and modules on a mass production scale. In light of this
observation, Meyer Burger together with the PV-Center of CSEM and the contribution of the Swiss Federal Office of
Energy and the State of Neuchâtel have started end 2013 a project to perform fully integrated R&D at the pilot scale with
an overall budget of 8.2 M€. The Swiss Inno-HJT project brings together the development from the sawing of thin wafers
using diamond wire technology, advanced cell concepts using proved Meyer Burger deposition equipments for Si-HJT
cell production and low cost metallization by plating at pilot scale at CSEM. These cells are then integrated in monofacial
and bifacial modules using the SmartWire technology and will be measured and monitored in outdoor conditions to show
the benefits in terms of kWh produced by Si-HJT modules compared to standard commercially available modules. This
contribution will report about the progresses of the Swiss Inno-HJT: High-lights will be the demonstration of busbar less
cell efficiencies above 23% done in a mass production environment and the first data from the outdoor monitoring of
modules.

description: In this paper we present the successful integration of a silicon heterojunction (HJ) solar cell with metal
wrap through architecture (MWT) and foil based- back contact module technology. With this contribution we show a
record cell efficiency of 20.3% achieved using commercial n-type Cz 6 inch wafers and demonstrate an encapsulated
cell efficiency of 19.6% achieved on a 2×2 mini-module. To our knowledge this is the first time that module results of
MWT-HJ architecture have been reported. In this studies , we propose a method to increase the solar cell performance
up to 21% together with a 50% cost of ownership reduction of the front silver metal including via and conductive
adhesive. This is possible solely by the optimization of the front metal grid. MWT-HJ is a fully low-temperature
integrated cell and module concept compatible also with thinner wafers.
Polarisation of molecular lines in the circumstellar envelope of the post-Asymptotic Giant Branch star OH 17.7-2.0

description: (abridged) The role of magnetic field in the shaping of Planetary Nebulae (PNe), either directly or indirectly after being enhanced by binary interaction, has long been a topic of debate. Large scale magnetic fields around pre-PNe have been inferred from polarisation observations of masers. However, because masers probe very specific regions, it is still unclear if the maser results are representative of the intrinsic magnetic field in the circumstellar envelope (CSE). Molecular line polarisation can provide important information about the magnetic field. A comparison between the field morphology determined from maser observations and that observed in the more diffuse CO gas, can reveal if the two tracers probe the same magnetic field. We compare observations taken with ALMA of molecular line polarisation around the post-Asymptotic Giant Branch)/pre-PNe star OH~17.7-2.0 with previous observations of polarisation in the 1612~MHz OH maser region. We detect CO~$J=2-1$ molecular line polarisation at a level of $\sim4\%$ that displays an ordered linear polarisation structure. We find that, correcting for Faraday rotation of the OH~maser linear polarisation vectors, the OH and CO linearly polarised emission trace the same large scale magnetic field. A structure function analysis of the CO linear polarisation reveals a plane-of-the-sky magnetic field strength of $B_\perp\sim1$~mG in the CO region, consistent with previous OH Zeeman observations. The consistency of the ALMA CO molecular line polarisation with maser observations indicate that both can be used to determine the magnetic field in CSEs. The existence of a strong, ordered, magnetic-field around OH 17.7-2.0 indicates that magnetic fields are likely involved in the formation of this bipolar pre-PNe.

description: Natural product chemistry is constantly challenged by newly discovered, complex molecules. Elements of complexity arise from unprecedented frameworks, with a large amount of densely packed stereogenic centres and different functional groups along with a generally high oxidation state. As a prime example, rearranged triterpenoids possess all these elements. For their total synthesis, a limit of what is considered sensible in terms of steps and yield is frequently reached. As an alternative, semisynthetic approaches have gained a great amount of attention in recent years. In this featured article, we present our and others' contributions towards the development of efficient and economic syntheses of complex terpenoid natural products and elaborate on the underlying rationale of biogenetic space-guided synthetic analysis.
