description: Thermal processing of as-made fluorozirconate glasses, which were additionally doped with rare earth and chlorine ions, leads to enhanced fluorescence intensities. For up-conversion applications, the glasses have been doped with trivalent neodymium ions as the active rare earth ion, while divalent europium has been used to develop down-conversion systems. The samples were annealed up to a temperature of 290°C to initiate the growth of BaCl2 nanocrystals therein; the rare earth is incorporated in the glass as well as in the nanoparticles. The particle diameters are in the range from a few nanometers to several tens of nanometers. The development of glass ceramics doped with erbium, whose luminescence characteristics make it a better choice for the application as an up-conversion layer on silicon solar cells, is in progress.

description: We investigate how confining a transverse spatial dimension influences the few- and many-body properties of non-relativistic bosons with pointlike interactions. Our main focus is on the dimensional crossover from three to two dimensions, which is of relevance for ultracold atom experiments. Using Functional Renormalization Group equations and T-matrix calculations we study how the phase transition temperature changes as a function of the spatial extent of the transverse dimension and relate the 3D and 2D s-wave scattering lengths. The analysis reveals how the properties of the lower-dimensional system are inherited from the higher-dimensional one during the renormalization group evolution. We limit the discussion to confinements in a potential well with periodic boundary conditions and argue why this qualitatively captures the physics of other compactifications such as transverse harmonic confinement as in cold atom experiments.

description: Simulation allows medical students to practice procedures and techniques in a controlled and safe environment, reducing the risk of patient harm. It utilizes either a standardized patient, virtual patient, or task
 trainer. However, using a single simulation modality can limit the scope of the scenarios that can be created, potentially limiting the learning experience. Simtegration uses more than one type of modality within the same simulation session. It is a hybrid form of simulation, allowing learners to practice and integrate technical and non-technical skills in a more realistic setting.

 The Department of Surgery at St. Luke’s Medical Center College of Medicine-William H. Quasha Memorial, Quezon City, Philippines, conducted a Simtegration clinical skills assessment of 28 medical intern rotators with the combined use of task trainers and standardized patients with favorable results.

description: Si/SiO2 single quantum wells and quantum dot layers were prepared under ultrahigh vacuum conditions in order to study their structural, chemical and photo-electrical properties with respect to a possible application in photovoltaic devices. Particular focus is put on the realization of well-defined and abrupt interfaces with low densities of interface gap states. The detection of a photocurrent in these quantum structures is demonstrated. Its spectral dependence correlates with the respective structural properties. Internal quantum efficiencies of photoconductivity and, thus, carrier mobility-lifetime products are strongly affected by Si/SiO2 interface states and were significantly enhanced upon hydrogen treatment due to passivation of interface gap states.

description: We consider singularly perturbed boundary value problems with a simple interior turning point whose solutions exhibit an interior layer. These problems are discretised using higher order finite elements on layer-adapted piecewise equidistant meshes proposed by Sun and Stynes. We also study the streamline-diffusion finite element method (SDFEM) for such problems. For these methods error estimates uniform with respect to $\varepsilon$ are proven in the energy norm and in the stronger SDFEM-norm, respectively. Numerical experiments confirm the theoretical findings.

description: Light induced (copper related) lifetime degradation has been studied in different solar cell silicon material. Especially the effect of oxygen level on the lifetime degradation has been investigated. The results show that oxygen plays a role in the lifetime degradation but is not necessary as the lifetime degradation can be seen also in float-zone (FZ) and low-oxygen cast silicon. However, copper concentration has to be much higher in FZ as compared to Czochralski (CZ) that the phenomenon is detectable.

description: We report the use of hydrogenated amorphous silicon carbide (a-SiC:H) prepared by plasma enhanced chemical vapor deposition (PECVD) as the photoelectrode in an integrated “hybrid” photoelectrochemical (PEC) cell to
produce hydrogen directly from water using sunlight. Results on the durability of hydrogenated amorphous silicon carbide (a-SiC:H) photoelectrodes in an electrolyte are presented. In a pH2 electrolyte, the a-SiC:H photoelectrode exhibits excellent stability for 100 hour test so far performed. A photocurrent onset shift (anodically) after a 24- or 100-hour durability test in electrolyte is observed, likely due to changes in the surface chemical structure of the a-SiC:H photoelectrode. It is also observed that a thin SiOx layer native to the air exposed surface of the a-SiC:H affects the photocurrent and the its onset
shift. Finally, approaches for eliminating the external bias voltage and enhancing the solar-to-hydrogen efficiency in a PV/PEC hybrid structure to achieve ≥10% are presented.

description: Generation of more than one free-carrier depends on a multistage nonlinear process and requires special dedicated low-energy centers. A cascade-like progression induced by an interband absorption allows a Si metamaterial to convert 400 nm photons into collectable primary and secondary free-carriers [1]. Such carriers can be drawn into the external electrical circuit even in a multiinterface architecture containing a carrier collection limit. (CCL). This conversion performance is inversely proportional to incident light intensity.
We have conceived and fabricated Si test structures containing a Si metamaterial by an amorphizing dose ionimplantation and suitable thermal treatment. The photoluminescence investigations of samples totally amorphized at the surface zone and with two states of the front face (passivated and bare) has allowed a clear visualization of specific nonradiative recombination mechanisms at the origin of the low-energy secondary generation. An optimization of the effect by suitable conditioning and annealing should be possible, opening the way to different applications, especially in the areas of nanophotovoltaics and ultrahigh efficiency solar cells.

We demonstrate the existence of a class of states for which entanglement is forever frozen during the dynamics, even if the state of the system does evolve. At the same time non-local correlations, quantified by the violation of the Clauser-Horne-Shimony-Holt (CHSH) inequality, either undergo sudden death or are trapped during the dynamics.

description: A four-junction solar cell design using monolithically integrated II/VI and III/V semiconductor materials on GaSb substrate is presented. The device structure is optimized to simplify the growth by varying both the bandgap energy and layer thickness of each subcell. Simulations show that the achievable AM0 energy conversion efficiency is 40% under 1 sun and 47% under 1000 suns. Preliminary experimental results of molecular beam epitaxy growth of II/VI materials on GaSb substrates is also reported; these materials include ZnTe bulk layers, ZnCdTe/ZnTe quantum wells, and CdSe/CdTe superlattices. In situ reflection high-energy electron diffraction measurements indicate a smooth and rapid transition from the III/V surface to the II/VI surface during growth. Post
growth characterization using X-ray diffraction, high-resolution transmission electron microscopy, and photoluminescence points to excellent structural, interfacial, and optical properties in these materials.

Compounds belonging to the group of I-III-VI2 chalcopyrites, currently used as absorbers in the leading thin-film technology, appear as promising candidates for the realization of IB-devices. In this paper we first analyze the expected performance of such a thin-film intermediate band solar cell (TF-IBSC) by considering different levels of idealization. In the second part of the paper some issues relevant for the practical realization of IBs in chalcopyrites are discussed and impurities acting as potential IB-precursors in the chalcopyrite sulfide host identified.

description: This paper presents a systematic approach to using the Socratic method in developing prompt templates that effectively interact with large language models, including GPT-3. Various methods are examined, and those that yield precise answers and justifications while fostering creativity and imagination to enhance creative writing are identified. Techniques such as {\em definition}, {\em elenchus}, {\em dialectic}, {\em maieutics}, {\em generalization}, and {\em counterfactual reasoning} are discussed for their application in engineering prompt templates and their connections to inductive, deductive, and abductive reasoning. Through examples, the effectiveness of these dialogue and reasoning methods is demonstrated. An interesting observation is made that when the task's goal and user intent are conveyed to GPT-3 via ChatGPT before the start of a dialogue, the large language model seems to connect to the external context expressed in the intent and perform more effectively.

description: We demonstrate currently reached results for depositing silicon thin films by crucible-free electron beam
physical vapor deposition (EB-PVD). The feasibility of a crucible-free EB-PVD could successfully be demonstrated in
experiments with different configurations of evaporation material. The process could be improved regarding the critical
aspects, e.g. occurrence of cracks during heating up and spill out of the melt on the melting pool edges. Deposition
rates above 500 nm/s, corresponding to 30 μm/min, have been reached. By using a double-ingot arrangement and
superposing vapor from multiple sources the relative deviation of layer thickness could be reduced to < ±5 % on a
substrate width of 200 mm (8 ). Furthermore, we investigated impacts of process parameters on layer stress.

description: In this paper, the influence of the voltage variations due to sources of series resistance on the solar cell
cell J-V curve is investigated. At first, the text book lumping approach for series resistance with its assumptions is
explained. Then, the local diode equation is expanded as a Taylor series to analyse what happens for small voltage
variations. Afterwards, the concept of a series resistance calculation based on voltage averaging is introduced. The
voltage averaging approach is more intuitive and easier to grasp, and is proven to be exactly equivalent to the text book
approach. Finally, the average current density in between two fingers will be calculated with a correct method for
current density averaging and compared to the value predicted by the text book approach to check its validity. It is
found that the text book approach is quite accurate for voltage variations that stay below the thermal voltage, but starts
to deviate for higher values.
Testing Models for the Shallow Decay Phase of Gamma-Ray Burst Afterglows with Polarization Observations

description: The X-ray afterglows of almost one half of gamma-ray bursts have been discovered to have a shallow decay phase by the {\em Swift} satellite, whose origin remains mysterious. Two main models have been proposed to explain this phase, relativistic wind bubbles (RWBs) and structured ejecta, which could originate from millisecond magnetars and rapidly-rotating black holes, respectively. Based on these models, we here investigate polarization evolution in the shallow decay phase of X-ray and optical afterglows. We find that in the RWB model, a significant bump of the polarization degree evolution curve appears during the shallow decay phase of both optical and X-ray afterglows, while the polarization position angle changes its direction by $90^\circ$ abruptly. In the structured ejecta model, however, the polarization degree does not evolve significantly during the shallow decay phase of afterglows, no matter whether the magnetic field configuration in the ejecta is random or globally large-scale. Therefore, we conclude that these two models for the shallow decay phase and relevant central engines would be testable with future polarization observations.

[Methods] Taking seedlings of S. tonkinensis as the research object, the response characteristics of chlorophyll and photosynthesis of S. tonkinensis were compared under different concentrations of copper and cadmium. [Results] With the increase of copper and cadmium treatment concentrations, the chlorophyll content first rose and then fell. With the increase of cadmium concentration, the net photosynthetic rate of S. tonkinensis plants increased from decrease to increase, and the stomatal conductance, transpiration rate and intercellular CO2 concentration all increased. [Conclusions] Under the stress of different concentrations of cadmium, the photosynthetic characteristics of S. tonkinensis were not obviously inhibited. Copper stress has inhibitory effect on photosynthesis of S. tonkinensis.

description: In this study, the properties of the intrinsic amorphous silicon (a-Si:H) and p-doped microcrystalline silicon (μc-Si:H) materials were investigated in a wide range of the deposition rates using the plasma enhanced chemical vapour deposition (PECVD) technique at the very high excitation frequency (VHF) and standard radio-frequency (RF). Thereby, the high-rate and low-rate regimes were compared. The material properties of the passivation layers as well as carrier lifetime were studied. Furthermore, the new p-type μc-Si:H electrodes were introduced. The initial growth process of the p-layer on top of the a-Si:H material was developed. Additionally, the influence of the ion bombardment energy on the deposition process is studied using simulation methods. At the final stage of the development, the dynamic VHF-PECVD process for the passivation and electrode layers has been introduced and applied for a highly productive fabrication of the heterojunction silicon solar cells (HIT).
Disentangling the origins of torque enhancement through wall roughness in Taylor-Couette turbulence

description: Direct numerical simulations (DNSs) are performed to analyze the global transport properties of turbulent Taylor-Couette flow with inner rough wall up to Taylor number $Ta=10^{10}$. The dimensionless torque $Nu_ω$ shows an effective scaling of $Nu_ω\propto Ta^{0.42\pm0.01}$, which is steeper than the ultimate regime effective scaling $Nu_ω\propto Ta^{0.38}$ seen for smooth inner and outer walls. It is found that at the inner rough wall, the dominant contribution to the torque comes from the pressure forces on the radial faces of the rough elements; while viscous shear stresses on the rough surfaces contribute little to $Nu_ω$. Thus, the log layer close to the rough wall depends on the roughness length scale, rather than on the viscous length scale. We then separate the torque contributed from the smooth inner wall and the rough outer wall. It is found that the smooth wall torque scaling follows $Nu_s \propto Ta_s^{0.38\pm0.01}$, in excellent agreement with the case where both walls are smooth. In contrast, the rough wall torque scaling follows $Nu_r \propto Ta_r^{0.47\pm0.03}$, very close to the pure ultimate regime scaling $Nu_ω\propto Ta^{1/2}$. The energy dissipation rate at the wall of inner rough cylinder decreases significantly as a consequence of the wall shear stress reduction caused by the flow separation at the rough elements. On the other hand, the latter shed vortices in the bulk that are transported towards the outer cylinder and dissipated. Compared to the purely smooth case, the inner wall roughness renders the system more bulk dominated and thus increases the effective scaling exponent.

description: In previous work, we have demonstrated the perfect integration on silicon of micrometric GaAs
crystals without any structural defects nor stress, using Epitaxal Lateral Overgrowth on Tunnel Oxide from nanoseeds
(ELTOn). Then, it would be very interesting to integrate the crystals in a regular way to have a quasi-complete
covering of the Si substrate, without coalescence of the GaAs microcrystals to maintain their very good electronic
properties, avoiding then detrimental grain boundaries. The main focus of this work is to address the issue of the
doping determination in a single micrometric size GaAs crystal which is a pre-requisite to develop the future design
and technology of multijunction solar cells based on an array of non-coalescent GaAs crystals free of structural
defects. In a previous work, local electrical characterizations by CP-AFM revealed a rather high non intentional ptype
doping. To obtain a quantitative estimation of the doping level, we propose a contactless method based on the
photoluminescence measurement of the evolution of the bandgap versus temperature and its modeling.

Impacts of three cultivation factors were analyzed: (i) three cultivation models (T1, T2 and T3), (ii) planting density (T1, T2 and T3), (iii) soil covering (T1, T2, T3, T4) on plant growth, and yield production. [Results] The soil moisture content, temperature, roots growth, stems development, leaf area index, and number-weight of tubers per plant and per plot (g) have significantly increased with commercial yield average of 45 t/ha.[Conclusions] The combination of this method with modern agriculture mechanization should be further popularized and applied in large scale planting in regions with climatic conditions similar winter season in Yunnan Province, so as to make contribution to the satisfaction of the world population potato consumption.

description: In this work, we have developed a new low cost low temperature curing (LTC) paste which is suitable
for Si hetero-junction (SHJ) solar cell. It is made of Cu particle coated with Ag, that is to say, Ag coated Cu paste. To
ensure the enough performance of LTC paste, Ag particles were blended with Ag coated Cu particles. We estimated
cost reduction rate due to Ag coated Cu paste, and investigated conductor and contact resistance of Ag coated Cu
paste electrode. Finally, we fabricated SHJ solar cells using the Ag coated Cu paste, and compared with Ag paste, the
difference of cell efficiency was relatively just only 0.4%. In conclusion, we were able to confirm that the newly
developed LTC Ag coated Cu paste replaces LTC Ag paste, and it can reduce about 30% of electrode cost of SHJ
solar cell.

description: This study explores the needed properties of both Transparent Conductive Oxides (TCOs) and the emitter region for bifacial homojunction solar cells with potentially passivated contacts. TCO layers with different electrical and optical properties have been tested on both sides of n-type homojunction cells for different resistivity of the boron doped region. The high lateral conductivity provided by the diffused emitter and back surface field (BSF) greatly reduces the constraints on TCO electrical properties in such structures. An understanding of the required properties of TCO for advanced homojunction applications is given. All in all moderately conductive TCOs on resistive junctions are shown to be suitable for such applications, allowing better optical properties and limitation of the recombinations losses without inducing resistive losses in the devices.
What do Health Workers say About Rural Practice?

Subjects: Preventative health care

description: Adequately staffed rural health services improve healthcare delivery and health outcomes, yet this is lacking in rural Ghana. We used a descriptive qualitative design to understand the contextual issues that affect rural practice, in the Upper East Region, Ghana. Sixty-eight in-depth interviews were conducted with healthcare workers and analysed thematically. Four themes were identified: types of postings to rural settings, healthcare workers’ perceptions of their rural postings, perceived enablers and motivators for rural practice, and perceived challenges and barriers to rural practice. While adequate supervision and family proximity are needed to improve the feelings of loneliness, isolation and neglect in rural areas, challenges and barriers such as inadequate security, unstable electricity supply, language barrier, lack of equipment and transport/ambulance have been identified to have negative influence on healthcare workers. The findings highlight the need for healthcare managers to improve fairness and transparency in the posting and reshuffling processes of healthcare workers.
We all have a role to play: Redressing inequities for children living with CAH and other chronic health conditions of childhood in resource-Poor settings

Subjects: Community child health

description: CLAN (Caring and Living as Neighbours) is an Australian-based non-governmental organisation (NGO) committed to equity for children living with chronic health conditions in resource-poor settings. Since 2004, CLAN has collaborated with a broad range of partners across the Asia Pacific region to improve quality of life for children living with congenital adrenal hyperplasia (CAH). This exploratory case study uses the Knowledge to Action (KTA) framework to analyse CLAN’s activities for children living with CAH in the Asia Pacific. The seven stages of the KTA action cycle inform a systematic examination of comprehensive, collaborative, sustained actions to address a complex health challenge. The KTA framework demonstrates the “how” of CLAN’s approach to knowledge creation and exchange, and the centrality of community development to multisectoral collaborative action across a range of conditions, cultures and countries to redressing child health inequities. This includes a commitment to: affordable access to essential medicines and equipment; education, research and advocacy; optimisation of medical management; encouragement of family support groups; efforts to reduce financial burdens; and ethical, transparent program management as critical components of success. Improvements in quality of life and health outcomes are achievable for children living with CAH and other chronic health conditions in resource-poor settings. CLAN’s strategic framework for action offers a model for those committed to #LeaveNoChildBehind.

description: Indium Tin Oxide (ITO) is widely used in solar cell devices for its excellent electrical and optical
characteristics, such as high transparency in the Ultraviolet-Visible range and good conductivity (around 104 -1cm-
1). In this work we have compared thin (70-150 nm) ITO layers deposited by Direct Current or Radio Frequency
sputtering. We have used different substrate temperatures during film growth and have afterwards thermally annealed
the samples at different temperatures up to 300°C to investigate the effects on the electrical and optical properties of
the material. We have found out that the different growth/annealing conditions induce changes in the optical
properties of the samples as well as in the conductivity and carrier concentration.
Using a nominal group technique to approach consensus on a resilience intervention for smoking cessation in a lower socioeconomic population

Subjects: Social determinants of health

description: Smoking prevalence remains inequitably high for lower SES (socioeconomic status) populations. The psychosocial interactive model of resilience theorises that resilience might be 'switched on' in order to support and/or maintain smoking cessation for these populations. This study aimed to develop a Resilience Intervention for Smoking Cessation (RISC) through reviewing the extant literature around efficacious interventions for smoking cessation. Deliberative democracy principles were then used to understand lay perspectives regarding this potential smoking cessation program. Methods: Public health databases were searched to find efficacious psycho-social resilience interventions in the peer-reviewed literature for smoking cessation amongst lower SES populations. Potential components for RISC were selected based on evidence within the literature for their effectiveness. We then employed the Nominal Group Technique (NGT) to create discussion and consensus on the most socially appropriate and feasible components from the perspective of smokers from low SES areas. The NGT included 16 people from a lower SES population in southern metropolitan Adelaide who indicated they were seriously contemplating quitting smoking or had recently quit. Data were collected from multiple Likert ratings and rankings of the interventions during the NGT workshop and analysed descriptively. The Wilcoxon signed-ranked test was used where appropriate. Qualitative data were collected from participant reflections and group discussion, and analysed thematically. Results: Six smoking cessation interventions, likely to enhance resilience, were selected as potential constituents for RISC: mindfulness training; setting realistic goals; support groups; smoke free environments; mobile phone apps; and motivational interviewing. Consensus indicated that mindfulness training and setting realistic goals were the most acceptable resilience enhancing interventions, based on perceived usefulness and feasibility. Conclusions: This research applied principles from deliberative democracy in order to illuminate lay knowledge regarding an appropriate and acceptable smoking cessation resilience program for a lower SES population. This process of collaborative and complex knowledge-generation is critically important to confront inequities as an ongoing challenge in public health, such as smoking cessation for disadvantaged groups. Further research should involve development and trial of this resilience program.
Pseudorapidity dependence of long-range two-particle correlations in pPb collisions at sqrt(s[NN]) = 5.02 TeV

description: Two-particle correlations in pPb collisions at a nucleon-nucleon center-of-mass energy of 5.02 TeV are studied as a function of the pseudorapidity separation (Delta eta) of the particle pair at small relative azimuthal angle (abs(Delta phi) < pi/3). The correlations are decomposed into a jet component that dominates the short-range correlations (abs(Delta eta) < 1), and a component that persists at large Delta eta and may originate from collective behavior of the produced system. The events are classified in terms of the multiplicity of the produced particles. Finite azimuthal anisotropies are observed in high-multiplicity events. The second and third Fourier components of the particle-pair azimuthal correlations, V[2] and V[3], are extracted after subtraction of the jet component. The single-particle anisotropy parameters v[2] and v[3] are normalized by their lab frame mid-rapidity value and are studied as a function of eta[cm]. The normalized v[2] distribution is found to be asymmetric about eta[cm] = 0, with smaller values observed at forward pseudorapidity, corresponding to the direction of the proton beam, while no significant pseudorapidity dependence is observed for the normalized v[3] distribution within the statistical uncertainties.

description: Dicaeum nigrilore Hartert Dicaeum nigrilore Hartert, 1904d: 8 (Mt. Apo, Southern Mindanao, 3000 feet above the sea). Now Dicaeum nigrilore nigrilore Hartert, 1904. See Salomonsen, 1960b: 20, Dickinson et al., 1991: 389–390, and Cheke and Mann, 2008b: 374. HOLOTYPE: AMNH 698360, adult male, collected on Mt. Apo, 3000 ft, 06.59N, 125.16E (Dickinson et al., 1991: 415), Mindanao Island, Philippines, in October 1903, by Johannes (5 John) Waterstradt (no. W. 302.a). From the Rothschild Collection. COMMENTS: Hartert cited Waterstradt’s field number of the holotype in the original description; both male and female were described. The number of specimens was not given, but Hartert (1920a: 430) recorded that Waterstradt had sent 13 specimens from Mt. Apo, some of them young. Hartert (1920b: 358), said ‘‘John Waterstradt collected not less than 14 specimens …’’ Fourteen specimens came to AMNH. The 13 paratypes are: Mt. Apo, October and November 1903, 3 males and 10 females, AMNH 698358, AMNH 698359, AMNH 698361–698371. I did not find AMNH 698363 in the collection, and it was perhaps exchanged to another institution without having been marked in the catalog. AMNH 698364 is the specimen illustrated in Hartert (1920b: 358 and pl. VI).
