description: Random numbers are important in many activities, including communication, encryption, science, gambling, finance, and decision-making. There is a strong demand for a hardware random number generator that could support cryptographic applications. In this work, we propose a quantum tunneling diode as a source of true randomness achieved by applying electrical current sweeps through the device and then harnessing a time-counting unit to measure fluctuation of current flows. Our approach can be implemented with inexpensive electronics and could be integrated into systems that require random numbers such as portable communication devices.

description: The radiative feedback of massive stars on molecular clouds creates pillars, globules and other features at the interface between the HII region and molecular cloud. We present here Herschel observations between 70 and 500 micron of the immediate environment of the Cygnus OB2 association, performed within the HOBYS program. All structures were detected based on their appearance at 70 micron, and have been classified as pillars, globules, evaporating gasous globules (EGGs), proplyd-like objects, and condensations. From the 70 and 160 micron flux maps, we derive the local FUV field on the PDR surfaces. In parallel, we use a census of the O-stars to estimate the overall FUV-field, that is 10^3-10^4 G_0 close to the central OB cluster (within 10 pc) and decreases down to a few tens G_0, in a distance of 50 pc. From a SED fit to the four longest Herschel wavelengths, we determine column density and temperature maps and derive masses, volume densities and surface densities for these structures. We find that the morphological classification corresponds to distinct physical properties. Pillars and globules have the longest estimated photoevaporation lifetimes, a few 10^6 yr, while all other features should survive less than that. These lifetimes are consistent with that found in simulations of turbulent, UV-illuminated clouds. We propose a tentative evolutionary scheme in which pillars can evolve into globules, which in turn then evolve into EGGs, condensations and proplyd-like objects.

title: An Investigation of Experimental Muscle Pain on Neuromuscular Fatigue and Endurance Performance
Creators: name: Norbury, Ryan
Publisher: name: University of Kent
Year: 2023

description: The determinants of exercise-induced fatigue are a contentious topic within exercise physiology and the limitations to endurance performance are still not fully understood. Exercise-induced pain is often present during high intensity exercise and typically occurs in parallel with exercise-induced fatigue. Therefore, it is possible that exercise-induced pain may be in part responsible for the development of neuromuscular fatigue and be a limitation to endurance performance. Therefore, the purpose of this thesis was to experimentally increase muscle pain and investigate the development of neuromuscular fatigue during endurance exercise. Experimental muscle pain was caused with an intramuscular injection of hypertonic saline into the vastus lateralis whereas an isotonic injection served as the non-painful control.Four experimental studies were conducted for this thesis. The first study aimed to investigate the test-retest reliability of an isometric time to task failure (TTF) of the knee extensors and measures of neuromuscular fatigue. This was to determine if these measures were sufficiently reliable to investigate the effects of pain on fatigue and endurance performance. The second study was to determine the effect of localised muscle pain on the performance of an isometric TTF of the knee extensors and measures of neuromuscular fatigue. Study three was to explore if non-local pain could also affect isometric endurance performance and the development of neuromuscular fatigue. The final study sought to investigate if whole-body, self-paced cycling exercise was also impaired by elevated muscle pain. The results of study one showed that an isometric knee extensor TTF displayed good reliability displayed by a coefficient of variation = 5.1% [95% CI: 2.9 - 7.3] and standard error of measurement = 21 s. Similarly, measures of neuromuscular fatigue displayed good reliability in the presence of exercise-induced fatigue (all coefficient of variation < 10%). Study two revealed that elevated muscle pain reduced isometric endurance time by 16% and this was due to a reduction in maximal strength and a reduction in voluntary activation (exacerbated central fatigue). Similarly, study three showed that non-local pain can reduce endurance time by 10% due to a decreased voluntary activation. Short duration self-paced cycling exercise remained largely unaffected in the presence of elevated muscle pain and the development neuromuscular fatigue was also unaltered. In conclusion, muscle pain appears to exacerbate the development of neuromuscular fatigue and impose a significant limitation to single-limb time to exhaustion exercise. However, self-paced exercise appears to be less affected by elevated pain and requires further investigation.

description: Colored c-Si PV cells or modules will allow a wider spread of Building Integrated Photovoltaic (BIPV) both on traditional roofs and on building facades. A few commercial products range from mono or multi crystalline colored PV cells to colored front protecting glasses. This paper presents the state of the art of some laboratory structures, their economical motivations and the results related to performances simulation. A general purpose simulation program developed at DEIB (Dipartimento di Elettronica, Informazione e Bioingegneria of Politecnico di Milano) allows the comparison of the power and color performances of the investigated structures. Three new structures have been simulated to improve the performances with no or very limited cost increase. In particular, we focused on tile-red cells, because of their high interest for PV roofing in the Mediterranean regions. For this reason, we propose a few samples deposited at the Nano Technology Laboratory (PoliFAB) of Politecnico di Milano.

description: A new approach based on the development of a new low-cost masking material is presented. The new
masking material based on a low-cost wax composition able to withstand wet hot chemical treatment at up to 100 °C.
The developed wax composition costs 10 times less than photoresist and can be taken into consideration as an
industrial masking process for solar cell for the front copper metallization process. In this work, applying and
removal procedures of wax mask are discussed. The applying procedure consists of rolling of wax film and further
patterning using laser ablation. Removal procedures are two: thermal and chemical. The procedures are investigated
using optical microscopy, reflectance spectroscopy and lifetime measurements. Finally, the proposed approach has
potential to enable front-side electroplated metallization at low cost.

description: Transitional disks are protoplanetary disks with opacity gaps/cavities in their dust distribution, a feature that may be linked to planet formation. We perform Bayesian modeling of the three transitional disks SZ Cha, CS Cha and T25 including photometry from the Herschel Space Observatory to quantify the improvements added by these new data. We find disk dust masses between 2x10^-5 and 4x10^-4 Msun, and gap radii in the range of 7-18 AU, with uncertainties of ~ one order of magnitude and ~ 4 AU, respectively. Our results show that adding Herschel data can significantly improve these estimates with respect to mid-infrared data alone, which have roughly twice as large uncertainties on both disk mass and gap radius. We also find weak evidence for different density profiles with respect to full disks. These results open exciting new possibilities to study the distribution of disk masses for large samples of disks.

 Citizen science has been taking an increasingly stable place among the components of open science in recent years. Citizen science activities allow interaction between various interested parties, from researchers to the users of the research results, which is an essential prerequisite for the well-being of society, scientific progress, and solving global problems.

 In 2022, a study was conducted in the Baltic States, which revealed various aspects of cooperation between scientists, amateur researchers, library and museum specialists in the context of citizen science. The research, using the method of a survey, proved that the involvement of both citizens and memory institutions in research is diverse, and that it is expanding with the development of open science. Researchers from the Baltic States expressed a positive opinion regarding cooperation with amateur researchers and specialists from memory institutions. On the other hand, the citizens highly appreciated the researchers' contribution to citizen science activities, their sharing of knowledge about the research process, methods, fields of science, as well as the shared experiences of new discoveries.

description: The results from the silicon heterojunction (SHJ) pilot line established at Arizona State University Solar Power Laboratory are presented. The pilot line is producing both front- and rear-emitter SHJ cells with 20.3% mean efficiency as well as bifacial cells with 20% front- and 19.5% rear-side efficiency. We also report 19% SHJ cells on 50-μm-thick wafers. The structure and optimization of the front- and rear-emitter cells is described. The key process improvements included (1) using IZO to achieve a good ohmic contact with (p+)a-Si layers, and using (n+)μc-Si as well as highly defective (n+)a-Si layers to ensure good ohmic contact with ITO; (2) using H2 plasma treatments of (i)a-Si layers to improve surface passivation; and (3) optimization of a-Si layers thickness to reduce optical and series resistance losses. Finally, an analysis of loss mechanisms in a 20% full wafer screen printed SHJ cell is presented and a roadmap towards 23% efficiency is discussed.

description: We describe a compactification of the six-dimensional (2,0) theory on a four-sphere which gives rise to a two-dimensional Toda theory at long distances. This construction realizes chiral Toda fields as edge modes trapped near the poles of the sphere. We relate our setup to compactifications of the (2,0) theory on the five and six-sphere. In this way, we explain a connection between half-BPS operators of the (2,0) theory and two-dimensional W-algebras, and derive an equality between their conformal anomalies. As we explain, all such relationships between the six-dimensional (2,0) theory and Toda field theory can be interpreted as statements about the edge modes of complex Chern-Simons on various three-manifolds with boundary.

description: We consider reinforcement learning (RL) in Markov Decision Processes in which an agent repeatedly interacts with an environment that is modeled by a controlled Markov process. At each time step $t$, it earns a reward, and also incurs a cost-vector consisting of $M$ costs. We design model-based RL algorithms that maximize the cumulative reward earned over a time horizon of $T$ time-steps, while simultaneously ensuring that the average values of the $M$ cost expenditures are bounded by agent-specified thresholds $c^{ub}_i,i=1,2,\ldots,M$. In order to measure the performance of a reinforcement learning algorithm that satisfies the average cost constraints, we define an $M+1$ dimensional regret vector that is composed of its reward regret, and $M$ cost regrets. The reward regret measures the sub-optimality in the cumulative reward, while the $i$-th component of the cost regret vector is the difference between its $i$-th cumulative cost expense and the expected cost expenditures $Tc^{ub}_i$. We prove that the expected value of the regret vector of UCRL-CMDP, is upper-bounded as $\tilde{O}\left(T^{2\slash 3}\right)$, where $T$ is the time horizon. We further show how to reduce the regret of a desired subset of the $M$ costs, at the expense of increasing the regrets of rewards and the remaining costs. To the best of our knowledge, ours is the only work that considers non-episodic RL under average cost constraints, and derive algorithms that can~\emph{tune the regret vector} according to the agent's requirements on its cost regrets.

description: This Policy Paper explores the potential of urban farming in Jordan to address the pressing issues of food security, climate-induced risks, and socioeconomic vulnerability in urban centers. With around 92% of Jordan’s citizens living in cities, and a significant refugee population residing in urban areas, the cities are highly vulnerable to disruptions in critical food supplies exacerbated by climate change and external shocks like the COVID-19 outbreak and Russia’s war in Ukraine. Vulnerable groups, including the urban poor, older people, youth, people with disabilities, and refugees in informal settlements, face precarious food and nutrition security. Urban farming, the practice of growing food in cities, is identified as a crucial solution to feed these vulnerable groups. The paper highlights the efficiency of urban farming, with innovative techniques providing up to 15 times higher productivity than conventional agriculture. Apart from addressing food security and health concerns, urban farming can play a vital role in enhancing cities’ resilience and employment opportunities. Moreover, it can act as a center for community engagement and youth education, while also providing ecological benefits. Karolina Zubel aims to showcase the environmental, ecological, and socioeconomic benefits of developing urban farming in Jordan from a sustainability and inclusivity perspective. By involving local communities and ensuring social dialogue, the development process can contribute to environmental and socioeconomic sustainability, preventing further vulnerability and exclusion. Additionally, it examines stakeholders’ perceptions, beneficiaries, and inclusivity in decision-making processes. The author explores governance challenges related to urban farm development, and discusses the prospects of such developments within the context of the European Green Deal diplomacy. The paper’s outcomes present a comprehensive understanding of the potential of urban farming in Jordan, emphasising its role in building resilience, enhancing food security, and promoting social inclusivity. The policy-oriented recommendations are designed to guide future actions and accelerate the development of urban farming across Jordan, fostering a sustainable and inclusive approach to address the complex challenges faced by urban populations.

description: The back side of Bifacial N-type Si solar cells has to be highly doped to form back surface field (BSF),
this results in low contact and good fill factor. However, highly doped back surface field increased Auger
recombination and high surface recombination. The motivation to form selective back surface field on n-type cells
from the selective emitter known for p-type cells. This paper applied two different process to create selective back
surface field and developed industrially applicable production sequence. The first one uses commercial etching paste
by screen printing to etch the regions between the contact metallization . The second process utilizes the wet chemical
etch back process where the areas intended for metallization are protected from etching by an acid resistant barrier.
Both techniques attain significant improvement (0.3% abs efficiency gain for etching paste and >0.4% abs for etch back
process) compared to standard cells with homogeneous back surface field. The influence of cell parameters and its
distribution are discussed, respectively.

AlOx/SiNx using a centrotherm tube PECVD system. Both stack systems were evaluated in PERC cell processes. The
SiONx/SiNx stack was implemented into two different mono PERC process flows, while the AlOx/SiNx stack was
integrated into mono and multi cell processes. A distinguishing property of AlOx is the field effect passivation induced
by negative fixed charges, which contributes to excellent passivation for p-type wafer since it avoids inversion layer
shunting. The passivation quality of SiONx/SiNx and AlOx/SiNx were characterized by QSSPC, corona charge
measurements and spectral response. Cell results of these two stack systems from different process flows were
examined.

description: In this work, the valence band offset (EV) and hole transport across the heterojunction between
amorphous silicon suboxides (a-SiOx:H) and crystalline silicon (c-Si) is investigated. Thin layers ranging from pure
intrinsic a-Si:H to near-stoichiometric a-SiO2 were grown by varying precursor gas mixtures during chemical vapor
deposition. A continuous increase of EV starting from ≈ 0 .3 eV for the a-Si:H/c-Si to > 4 eV for the a-SiO2/c-Si
heterointerface was measured by in-system photoelectron spectroscopy. Furthermore, (p)a-Si:H/(i)a-SiOx:H/(n)c-
Si/(i,n+)a-Si:H heterojunction solar cells, with intrinsic a-SiOx:H passivation layers deposited using the same
parameter sets, were fabricated. We report a linear decrease of the solar cell fill factor for increasing EV in the range
of 0.27 – 0.85 eV. The reason is an increase of the barrier height for holes at the (i)a-SiOx:H/(n)c-Si heterojunction
and a simultaneous change of the hole transport mechanism from thermionic emission to defect-assisted tunnel
hopping through valence-band tail-states. It is demonstrated that as compared to a single layer, significantly larger
barrier heights can be tolerated in a stack of high band gap material and a material with lower band gap, forming a
staircase of band offsets. This could allow the application of these layers in silicon heterojunction solar cells.

description: Ray tracing radiative transfer is a powerful method for comparing theoretical models of black hole accretion flows and jets with observations. We present a public code, grtrans, for carrying out such calculations in the Kerr metric, including the full treatment of polarised radiative transfer and parallel transport along geodesics. The code is written in Fortran 90 and efficiently parallelises with OpenMP, and the full code and several components have Python interfaces. We describe several tests which are used for verifiying the code, and we compare the results for polarised thin accretion disc and semi-analytic jet problems with those from the literature as examples of its use. Along the way, we provide accurate fitting functions for polarised synchrotron emission and transfer coefficients from thermal and power law distribution functions, and compare results from numerical integration and quadrature solutions of the polarised radiative transfer equations. We also show that all transfer coefficients can play an important role in predicted images and polarisation maps of the Galactic center black hole, Sgr A*, at submillimetre wavelengths.

description: We exploit the reduced space of C. elegans postures to develop a novel tracking algorithm which captures both simple shapes and also self-occluding coils, an important, yet unexplored, component of worm behavior. We apply our algorithm to show that visually complex, coiled sequences are a superposition of two simpler patterns: the body wave dynamics and a head-curvature pulse. We demonstrate the precise coiled dynamics of an escape response and uncover new behaviors in spontaneous, large amplitude coils; deep reorientations occur through classical Omega-shaped postures and also through larger, new postural excitations which we label here as delta-turns. We find that omega and delta turns occur independently, the serpentine analog of a random left-right step, suggesting a distinct triggering mechanism. We also show that omega and delta turns display approximately equal rates and adapt to food-free conditions on a similar timescale, a simple strategy to avoid navigational bias.

were used to find the best passivation related process parameters. Hydrophilic (-OH) or hydrophobic (-H) was formed
in different chemical cleaning solution before ALD AlOx. 5-15nm AlOx was deposited on the double sides of the
cleaned silicon wafers to check the thickness and blisters influence on the effective lifetime. After annealed in
N2(with 10% O2) at 550-650, high effective lifetime was obtained before capping SiNx. The lifetime decayed
dramatically after PECVD SiNx. However, anneal at 600 in N2 after capping SiNx can raise the lifetime about 50%
and keep it after firing. It is found that ALD AlOx passivation is very sensitive to the pre treatment, for example,
various soaking time of HNO3 before ALD AlOx will affect the lifetime seriously till after firing for N-type silicon
wafers, while no obvious difference for boron diffused N-type wafers before capping SiNx. So specific prior
treatment and post anneal process are needed for different wafers.

description: Aims. Study the connection between the masing disk and obscuring torus in Seyfert 2 galaxies. Methods. We present a uniform X-ray spectral analysis of the high energy properties of 14 nearby megamaser Active Galactic Nuclei observed by NuSTAR. We use a simple analytical model to localize the maser disk and understand its connection with the torus by combining NuSTAR spectral parameters with available physical quantities from VLBI mapping. Results. Most of the sources analyzed are heavily obscured, showing a column density in excess of $\sim 10^{23}$ cm$^{-2}$. In particular, $79\%$ are Compton-thick ($N_{\rm H} > 1.5 \times 10^{24}$ cm$^{-2}$). Using column densities measured by NuSTAR, with the assumption that the torus is the extension of the maser disk, and further assuming a reasonable density profile, the torus dimensions can be predicted. They are found to be consistent with mid-IR interferometry parsec-scale observations of Circinus and NGC 1068. In this picture, the maser disk is intimately connected to the inner part of the torus. It is probably made of a large number of molecular clouds connecting the torus and the outer part of the accretion disk, giving rise to a thin disk rotating in most cases in Keplerian or sub-Keplerian motion. This toy model explains the established close connection between water megamaser emission and nuclear obscuration as a geometric effect.

description: We show that for any Carnot group $G$ there exists a natural number $D_G$ such that for any $0<\varepsilon<1/2$ the metric space $(G,d_G^{1-\varepsilon})$ admits a bi-Lipschitz embedding into $\mathbb{R}^{D_G}$ with distortion $O_G(\varepsilon^{-1/2})$. This is done by building on the approach of T. Tao (2021), who established the above assertion when $G$ is the Heisenberg group using a new variant of the Nash--Moser iteration scheme combined with a new extension theorem for orthonormal vector fields. Beyond the need to overcome several technical issues that arise in the more general setting of Carnot groups, a key point where our proof departs from that of Tao is in the proof of the orthonormal vector field extension theorem, where we incorporate the Lovász local lemma and the concentration of measure phenomenon on the sphere in place of Tao's use of a quantitative homotopy argument.

A Force-Level Theory of the Rheology of Entangled Rod and Chain Polymer Liquids. I. Tube Deformation, Microscopic Yielding and the Nonlinear Elastic Limit

description: We employ a first principles, force-level approach to self-consistently construct the anharmonic tube confinement field for entangled fluids of rigid needles and for primitive-path (PP) level chains in two limiting situations where chain stretching is assumed to either completely relax or remain unrelaxed. The influence of shear and extensional deformation and polymer orientation is determined in a nonlinear elastic limit where dissipative relaxation processes are intentionally neglected. For needles and PP-level chains, a Gaussian analysis of transverse polymer dynamical fluctuations predicts that deformation-induced orientation leads to tube dilation. In contrast, for deformed polymers in which chain stretch does not relax we find tube compression. For all three systems, a finite maximum transverse entanglement force localizing the polymers in effective tubes is predicted. The conditions when this entanglement force can be overcome (a force imbalance) by an externally applied force associated with macroscopic deformation can be crisply defined in the nonlinear elastic limit, and the possibility of a "microscopic absolute yielding" event destroying the tube confinement can be analyzed. For needles and contour-relaxed PP chains, this force imbalance is found to occur at a stress of order the equilibrium shear modulus and thus a strain of order unity, corresponding to a mechanically fragile entanglement tube field. However, for unrelaxed stretched chains, tube compression stabilizes transverse polymer confinement, and there appears to be no force imbalance. These results collectively suggest that the crossover from elastic to irreversible viscous response requires chain retraction to initiate disentanglement. We qualitatively discuss comparisons with existing phenomenological models for nonlinear startup shear, step strain, and creep rheology experiments.

description: The state of vanishing friction known as superlubricity has important applications for energy saving and increasing the lifetime of devices. Superlubricity detected with atomic force microscopy appears in examples like sliding large graphite flakes or gold nanoclusters across surfaces. However, the origin of the behavior is poorly understood due to the lack of a controllable nano-contact. We demonstrate graphene nanoribbons superlubricity when sliding on gold with a joint experimental and computational approach. The atomically well-defined contact allows us to trace the origin of superlubricity, unravelling the role played by edges, surface reconstruction and ribbon elasticity. Our results pave the way to the scale-up of superlubricity toward the realization of frictionless coatings.

description: With the growth of available computational resource, CFD-DEM (computational fluid dynamics-discrete element method) becomes an increasingly promising and feasible approach for the study of sediment transport. Several existing CFD-DEM solvers are applied in chemical engineering and mining industry. However, a robust CFD-DEM solver for the simulation of sediment transport is still desirable. In this work, the development of a three-dimensional, massively parallel, and open-source CFD-DEM solver SediFoam is detailed. This solver is built based on open-source solvers OpenFOAM and LAMMPS. OpenFOAM is a CFD toolbox that can perform three-dimensional fluid flow simulations on unstructured meshes; LAMMPS is a massively parallel DEM solver for molecular dynamics. Several validation tests of SediFoam are performed using cases of a wide range of complexities. The results obtained in the present simulations are consistent with those in the literature, which demonstrates the capability of SediFoam for sediment transport applications. In addition to the validation test, the parallel efficiency of SediFoam is studied to test the performance of the code for large-scale and complex simulations. The parallel efficiency tests show that the scalability of SediFoam is satisfactory in the simulations using up to O(10^7) particles.

description: We localize the sources of brain activity of children with epilepsy based on EEG recordings acquired during a visual discrimination working memory task. For the numerical solution of the inverse problem, with the aid of age-specific MRI scans processed from a publicly available database, we use and compare three regularization numerical methods, namely the standarized Low Resolution Electromagnetic Tomography (sLORETA), the weighted Minimum Norm Estimation (wMNE) and the dynamic Statistical Parametric Mapping (dSPM). We show that all three methods provide the same spatio-temporal patterns of differences between epileptic and control children. In particular, our analysis reveals statistically significant differences between the two groups in regions of the Parietal Cortex indicating that these may serve as "biomarkers" for diagnostic purposes and ultimately localized treatment.

title: On the nature of entropy and complexity in psychology

description: The link between entropy and complexity is the cornerstone of all complex systems. Despite their significance and previous research indicating that the principles of entropy and complexity can be applied to psychological systems, a theoretically and methodologically comprehensive examination of their link has remained largely unexplored in psychology. To address this, the present research investigated the link between entropy and complexity in psychological systems. Drawing on the theoretical and methodological approaches of complexity science, this research examined the link across three distinct yet interrelated lines of investigation that consisted of nine online studies (N = 665) and used a combination of linear and nonlinear analysis techniques. In Part I, the link was examined in relation to patterns, with the evaluation of the stimulus being the focus of the investigation. In Parts II and III, the link was examined in relation to processes, with the response to the stimulus being the focus of the investigation. More specifically, Part II focused on processes at the macro-level, after which Part III extended the focus to both the macro- and micro-levels. On the whole, the present research established and empirically validated an integrative perspective on how entropy and complexity – two fundamental concepts that are essential for understanding complex systems in nature – impact the dynamics of psychological systems.
