description: The evaluation of photovoltaic (PV) systems under real field conditions is considered of utmost
importance in assessing the actual performance of different technologies and although data regarding the
performance comparison of PV systems has been reported in the past, the error margins on the evaluated parameters
are often presented as an approximate value or underestimated. The outdoor test facilities in Stuttgart, Germany and
Nicosia, Cyprus include 13 grid-connected PV systems of the latest technologies and of nominal power 1 kWp each.
PV system performance indicators have been extracted using state-of-the-art monitoring and measurement systems
and evaluations have been carried out for more than three years. The highest performance parameter errors as a result
of error propagation from the sensors and other measuring devices were observed on the performance ratio (PR),
temperature coefficient and efficiency evaluations. For the temperature coefficient evaluation it was found that other
effects such as dust, degradation and spectrum are more important than the sensors error accuracy, especially in the
case of thin film technologies. The purpose of this work is to determine and quantify the error sources associated
with outdoor testing and to outline procedures and techniques to minimise these.

description: The cryogenic underground observatory for rare events (CUORE) is a 1-ton scale bolometric experiment whose detector consists of an array of 988 TeO2 crystals arranged in a cylindrical compact structure of 19 towers. This will be the largest bolometric mass ever operated. The experiment will work at a temperature around or below 10 mK. CUORE cryostat consists of a cryogen-free system based on pulse tubes and a custom high power dilution refrigerator, designed to match these specifications. The cryostat has been commissioned in 2014 at the Gran Sasso National Laboratories and reached a record temperature of 6 mK on a cubic meter scale. In this paper, we present results of CUORE commissioning runs. Details on the thermal characteristics and cryogenic performances of the system will be also given.

description: The permanent deactivation of the recombination-active boron-oxygen complex, which consists of one substitutional boron atom and one interstitial oxygen dimer, in boron-doped Czochralski-grown silicon is demonstrated on low-resistivity lifetime samples as well as on high-efficiency RISE-EWT (Rear Interdigitated Single Evaporation Emitter Wrap-Through) solar cells. Furthermore, we describe a model capable of explaining the time dependence of the lifetime evolution during the deactivation process, introducing a second defect reaction which results in the binding of the oxygen dimer in a recombination-inactive complex. The application of the deactivation procedure to RISE-EWT solar cells results in an increase of the stabilized energy conversion efficiency from 19.1 % to 20.3 %.

description: The integration of photovoltaics in buildings is a key to the future of PV technology. Architects and
engineers are willing to integrate PV into their overall design projects and concepts. We know that architects are
restricted to selecting PV technologies that are on the market. Further research into building integrated PV is also
required to achieve the aims of architects and designers, which is to enhance the use of this technology in their buildings.
The increased use of this technology in building integrated PV (BIPV) and research into thin films is expected to be
ongoing in the medium and long terms to reduce the costs of the technology in such applications. For thin films, high
efficiency is the key to reducing the cost per rated watt of product in the long term. Third generation PV may triple
efficiencies and hence significantly reduce costs of thin-film cells and modules. The possible uses of thin film PV in
BIPV are wide ranging. And what important architectural and engineering characteristics must it have to make it suitable
in BIPV? As the efficiency of thin-film cells continues to rise, their flexibility of use in BIPV will increase, making them
a great asset. PV researchers are aiming for greater efficiency. Architects want to use PV in new applications and
integration methods and want PV modules with improved aesthetics for specific projects. The solar industry is looking
for cost-effectiveness in PV. The requirements of architects for the enhanced integration of photovoltaic’s into buildings
are demonstrated.

description: Coronavirus disease 2019 (COVID-19) increases the risk of coagulopathy. Although the presence of antiphospholipid antibodies (aPLs) has been proposed as a possible mechanism of COVID-19-induced coagulopathy, its clinical significance remains uncertain. Therefore, this study aimed to evaluate the prevalence and clinical significance of aPLs among critically ill patients with COVID-19. This prospective observational study included 60 patients with COVID-19 admitted to intensive care units (ICU). The study outcomes included prevalence of aPLs, and a primary composite outcome of all-cause mortality and arterial or venous thrombosis between antiphospholipid-positive and antiphospholipid-negative patients during their ICU stay. Multiple logistic regression was used to assess the influence of aPLs on the primary composite outcome of mortality and thrombosis. A total of 60 critically ill patients were enrolled. Among them, 57 (95%) were men, with a mean age of 52.8 ± 12.2 years, and the majority were from Asia (68%). Twenty-two patients (37%) were found be antiphospholipid-positive; 21 of them were positive for lupus anticoagulant, whereas one patient was positive for anti-β2-glycoprotein IgG/IgM. The composite outcome of mortality and thrombosis during their ICU stay did not differ between antiphospholipid-positive and antiphospholipid-negative patients (4 [18%] vs. 6 [16%], adjusted odds ratio 0.98, 95% confidence interval 0.1–6.7; p value = 0.986). The presence of aPLs does not seem to affect the outcomes of critically ill patients with COVID-19 in terms of all-cause mortality and thrombosis. Therefore, clinicians may not screen critically ill patients with COVID-19 for aPLs unless deemed clinically appropriate.Other Information Published in: Rheumatology International

description: We describe a process to manufacture ultrathin photovoltaic (PV) cells from crystalline silicon and
gallium arsenide. The method uses technologies developed for microsystems and has been proven to release small
form factor (< 1 mm) and ultrathin solar cells (1.15 μm thick for GaAs, and down to 14 μm in crystalline silicon)
with demonstrated functionality. The 14 μm thick c-Si solar cells have achieved efficiencies in excess of 10%. The
scale of these cells provide significant benefits for low, medium, and high concentration solar power. These benefits
include simplified thermal management, better optical efficiency of the concentrating system, and low-cost module
assembly. Due to these advantages over larger scale cells, our economic models predict that this technology could
provide $0.50/Wpeak module manufacturing costs with additional savings in the balance of system costs relative to
current PV system technologies.

description: Anatomic variations involving arterial supply of the large intestines are of clinical significance. Variations range from the pattern of origin, branching and territorial supply. The colon, the part of the large intestine, usually receives its arterial blood supply from branches of the superior and inferior mesenteric arteries. However, anatomic variation in this vascular arrangement has been reported, with vascular anatomy of the right colon being described as complex and more variable compared with the left colon. During routine cadaveric dissection of the supracolic and infracolic viscera, we encountered an additional mesenteric artery originating directly from the anterior surface of the abdominal aorta between the origins of the superior and inferior mesenteric arteries. This additional “inferior mesenteric artery” ran obliquely superiorly toward the left colon giving rise to two branches supplying the distal part of the ascending colon, the transverse colon and the proximal part of the descending colon. Awareness and knowledge of this anatomic variation are important for radiologists and surgeons to improve the quality of surgery and avoid both intra- and postoperative complications during surgical procedures of the colon.Other Information Published in: Surgical and Radiologic Anatomy

description: The Circum-Galactic Medium (CGM) can be probed through the analysis of absorbing systems in the line-of-sight to bright background quasars. We present measurements of the metallicity of a new sample of 15 sub-damped Lyman-$α$ absorbers (sub-DLAs, defined as absorbers with 19.0 < log N(H I) < 20.3) with redshift 0.584 < $\rm z_{abs}$ < 3.104 from the ESO Ultra-Violet Echelle Spectrograph (UVES) Advanced Data Products Quasar Sample (EUADP). We combine these results with other measurements from the literature to produce a compilation of metallicity measurements for 92 sub-DLAs as well as a sample of 362 DLAs. We apply a multi-element analysis to quantify the amount of dust in these two classes of systems. We find that either the element depletion patterns in these systems differ from the Galactic depletion patterns or they have a different nucleosynthetic history than our own Galaxy. We propose a new method to derive the velocity width of absorption profiles, using the modeled Voigt profile features. The correlation between the velocity width delta_V90 of the absorption profile and the metallicity is found to be tighter for DLAs than for sub-DLAs. We report hints of a bimodal distribution in the [Fe/H] metallicity of low redshift (z < 1.25) sub-DLAs, which is unseen at higher redshifts. This feature can be interpreted as a signature from the metal-poor, accreting gas and the metal-rich, outflowing gas, both being traced by sub-DLAs at low redshifts.

description: In search of states with non-Abelian statistics, we explore the fractional quantum Hall effect in a system of two-dimensional charge carrier holes. We propose a new method of mapping states of holes confined to a finite width quantum well in a perpendicular magnetic field to states in a spherical shell geometry. This method provides single-particle hole states used in exact diagonalization of systems with a small number of holes in the presence of Coulomb interactions. An incompressible fractional quantum Hall state emerges in a hole liquid at the half-filling of the ground state in a magnetic field in the range of fields where single-hole states cross. This state has a negligible overlap with the Halperin 331 state, but a significant overlap with the Moore-Read Pfaffian state. Excited fractional quantum Hall states for small systems have sizable overlap with non-Abelian excitations of the Moore-Read Pfaffian state.

description: Solar cell technologies based on silicon wafers dominate the market since the beginning of industrial production of photovoltaic modules. Future objectives are the reduction of the silicon wafer thickness and a reduction of fabrication costs. We present new results for the fabrication of solar cells according to our new concept by Albonding of silicon wafers to a supporting glass substrate. The bonding process is carried out in a Rapid Thermal Processing (RTP)-furnace and integrated in the fabrication of the pn-junction, Al-Back Surface Field (BSF) and the backside metal contact. We optimized this technology for extra thin (90 μm) multicrystalline silicon wafers, the best solar cells show an efficiency of 15%. The results of quantum efficiency and light beam inducted current (LBIC) are discussed.

description: Background Early identification of patients who may need massive blood transfusion remains a major challenge in trauma care. This study proposed a novel and easy-to-calculate prediction score using clinical and point of care laboratory findings in patients with abdominal trauma (AT). Methods Patients with AT admitted to a trauma center in Qatar between 2014 and 2017 were retrospectively analyzed. The FASILA score was proposed and calculated using focused assessment with sonography in trauma (0 = negative, 1 = positive), Shock Index (SI) (0 = 0.50–0.69, 1 = 0.70–0.79, 2 = 0.80–0.89, and 3 ≥ 0.90), and initial serum lactate (0 ≤ 2.0, 1 = 2.0–4.0, and 2 ≥ 4.0 mmol/l). Outcome variables included mortality, laparotomy, and massive blood transfusion (MT). FASILA was compared to other prediction scores using receiver operating characteristics and areas under the curves. Bootstrap procedure was employed for internal validation. Results In 1199 patients with a mean age of 31 ± 13.5 years, MT, MT protocol (MTP) activation, exploratory laparotomy (ExLap), and hospital mortality were related linearly with the FASILA score, Injury Severity Score, and total length of hospital stay. Initial hemoglobin, Revised Trauma Score (RTS), and Trauma Injury Severity Score (TRISS) were inversely proportional. FASILA scores correlated significantly with the Assessment of Blood Consumption (ABC) (r = 0.65), Revised Assessment of Bleeding and Transfusion (RABT) (r = 0.63), SI (r = 0.72), RTS (r = − 0.34), and Glasgow Coma Scale (r = − 0.32) and outperformed other predictive systems (RABT, ABC, and SI) in predicting MT, MTP, ExLap, and mortality. Conclusions The novel FASILA score performs well in patients with abdominal trauma and offers advantages over other scores.Other Information Published in: World Journal of Surgery

description: Purpose Total knee arthroplasty is one of the significantly evolving procedures with different knee designs available in the market. The continued development of these prosthesis resulted in improvement of the implant survivorship and patient satisfaction. This study is an RCT-based meta-analysis aimed to compare two designs of total knee replacement: the conventional modular and the monoblock trabecular metal tibial trays. Methods This meta-analysis was performed by a literature review according to the PRISMA guidelines. A detailed search of the English literature was done using the PubMed, Medline, CINAHL, Cochrane, Embase, and Google Scholar databases. Only randomized control trials were included in the analysis after ensuring homogeneity. RevMan V.5.0.18.33 (The Cochrane Collaboration, Copenhagen, Denmark) was used to perform the meta-analysis. Extracted outcome measures were Knee Society score, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, survivorship, complication rate, and radiostereographic analysis. Results Seven randomized control trials with 635 patients were eligible for our analysis after they met our inclusion criteria. Three hundred twelve patients received monoblock tibias, and the other 323 patients received modular tibial trays during their total knee arthroplasty surgeries. There were statistically significant superiority of the modular knees in the functional Knee Society and WOMAC scores at five years (P = 0.003 and 0.05, respectively). The modular design was also more stable on RSA at two years (P < 0.0001). Conclusion Modular and monoblock tibial trays are comparable knee designs with comparable survivorship and complication rates. However, the modular knees had better mid-term functional outcome and are more stable on radiostereographic analysis.Other Information Published in: International Orthopaedics

description: Since 2000, Fraunhofer ISE prepared yield certificates for some 400 PV systems. The institute also operates
monitoring equipment at some 200 PV installations, with some of them for more than 6 years now. For an intersection
of more than 30 PV systems, we have access both to the original yield certificates and to data sets of meteorological
and plant performance data. On this data base, different comparisons are carried out:
• A straightforward comparison looks at predicted and observed yield, irradiation and performance ratios (PR)
• For systems with DC measurements available we compare the “DC-PR” and the “AC-PR”
• A more in-depth method is named “weather adjusted yield certificate”. Here, observed time series of solar irradiation
and ambient temperature are fed into the same prediction routines as used with the certificate calculations.
In the following, all parameters measured on site may be compared to the relevant values of the prediction
routine.
The overall deviation in energy yield is +3.7 % with a standard deviation of 4.2 %. Most of the deviation results from
higher irradiation in the recent years compared to the long term average. So the average deviation in PR for the systems
is 0.7 %-points with a standard deviation of 2.5 %-points. This deviation is covered by the uncertainty estimation in the
yield certificate.

description: This work is an overview of the activities performed in the issues of simulation and characterization of III-V solar cells for space applications within the cooperation agreement between the Argentine National Atomic Energy Commission (CNEA) and the Argentine National Commission for Space Activities (CONAE), which is addressed in these first stages to SAOCOM and SAC-D satellites. These activities include numerical simulation of III-V homojunction solar cells (InGaP and GaAs) and Ge cells, and its virtual interconnection in order to simulate a triple junction (TJ) InGaP/GaAs/Ge cell, the same type that will be used in the solar arrays of the next CONAE satellites. The simulation tools developed here can be extended to other multijunction devices and can also be used for their optimization. On the other hand, while electrical characterization of TJ cells was presented in othe contributions, here the development of an equipment to measure the spectral response on triple junction III-V solar cells based on interference narrow band filters and dichroic lamps as polarization light to select the subcell to be measured is showed. Results in both activities are demonstrated.

Methods This meta-analysis was conducted with adherence to PRISMA guidelines. PubMed, Cochrane, Web of Science, and Google Scholar were searched until February 2022. Inclusion criteria were as follows: all studies in which the patients with joint replacements were evaluated for PJI; synovial Calprotectin was the biomarker of choice to diagnose PJI; standardized guidelines were used as the gold standard for the diagnosis; and a comparison between the guidelines and Calprotectin results was made. Diagnostic parameters such as sensitivity, specificity, diagnostic odds ratio (DOR), positive predictive value, negative predictive value, and area under the curve (AUC) were calculated for the included studies to evaluate synovial Calprotectin for PJI diagnosis. Results The total number of the included patients was 618 from eight studies. The pooled sensitivity, specificity, and diagnostic odds ratio of Calprotectin test were 92% (95%CI: 84%-98%), 93% (95%CI: 84%-99%), and 187.61 (95%CI: 20.21–1741.18), respectively. The results showed that the negative and positive likelihood ratios of the Calprotectin test were 0.07 (95%CI: 0.02–0.22) and 9.91 (95%CI: 4.11–23.93), respectively. The SROC showed that the area under the curve for Calprotectin test was 0.935. Conclusion Synovial Calprotectin is a valuable biomarker as it provides a reliable and rapid diagnosis of PJI. It has the potential to be used in clinical practice due to its high sensitivity and specificity that are comparable to the other utilized biomarkers. Another advantage is its low cost relative to other biomarkers.Other Information Published in: International Orthopaedics

description: Tuberous sclerosis complex (TSC) turns off cell growth in response to energy stress by inhibiting the master kinase mechanistic target of rapamycin complex (mTORC1). TSC hydrolyzes RAS homolog-mTORC1 binding (RHEB) from its GTP-bound to GDP-bound state, preventing the allosteric activation of mTORC1. Loss-offunction TSC mutations hyperactivate mTORC1 resulting in the common genetic disorder TSC characterized by excess cell growth and tumor formation. Here we overcome a high degree of continuous conformational heterogeneity to determine the 2.9 Å cryo-electron microscopy (cryo-EM) structure of the complete human TSC in complex with the lysosomal recruitment factor WIPI3. TSC forms an elongated 40 nm wing-like structure with a core HEAT-repeat scaffold formed by a TSC2 dimer joined centrally by the juxtaposition of two catalytic domains. The TSC1 coil-coil dimer runs across the TSC2 surface, forming a previously undetected N-terminal TSC1 dimer that clamps onto the core scaffold on a single TSC wing. Structural and biochemical analysis reveals a novel phosphatidylinositol phosphate (PIP)-binding pocket in the TSC1 dimer interface that specifically binds singularly phosphorylated PIPs. WD repeat domain phosphoinositide-interacting-protein-3 (WIPI3) binds to the extreme tip of the complex through a conserved motif in TSC1, providing a second membrane anchor point for TSC lysosomal recruitment. The TSC:WIPI3 complex helps explain how TSC lysosomal recruitment proteins coordinate with endolysosomal phosphoinositide-signaling networks to regulate TSC localization, RHEB hydrolysis, and mTORC1 inhibition. More broadly, the high-resolution structure of the complete human TSC identifies novel mutational hotspots that unravel crucial new mechanisms of TSC dysregulation in disease.

description: We present extensively dense observations of the super-Chandrasekhar supernova (SC SN) candidate SN 2012dn from $-11$ to $+140$ days after the date of its $B$-band maximum in the optical and near-infrared (NIR) wavelengths conducted through the OISTER ToO program. The NIR light curves and color evolutions up to 35 days after the $B$-band maximum provided an excellent match with those of another SC SN 2009dc, providing a further support to the nature of SN 2012dn as a SC SN. We found that SN 2012dn exhibited strong excesses in the NIR wavelengths from $30$ days after the $B$-band maximum. The $H$ and $K_{s}$-band light curves exhibited much later maximum dates at $40$ and $70$ days after the $B$-band maximum, respectively, compared with those of normal SNe Ia. The $H$ and $K_{s}$-band light curves subtracted by those of SN 2009dc displayed plateaued evolutions, indicating a NIR echo from the surrounding dust. The distance to the inner boundary of the dust shell is limited to be $4.8 - 6.4\times10^{-2}$ pc. No emission lines were found in its early phase spectrum, suggesting that the ejecta-CSM interaction could not occur. On the other hand, we found no signature that strongly supports the scenario of dust formation. The mass loss rate of the pre-explosion system is estimated to be $10^{-6}-10^{-5}$ M$_{\odot}$ yr$^{-1}$, assuming that the wind velocity of the system is $10-100$ km~s$^{-1}$, which suggests that the progenitor of SN 2012dn could be a recurrent nova system. We conclude that the progenitor of this SC SN could be explained by the single-degenerate scenario.

description: We describe the optical characterisation of two silicon cold-electron bolometers each consisting of a small ($32 \times 14~\mathrm{μm}$) island of degenerately doped silicon with superconducting aluminium contacts. Radiation is coupled into the silicon absorber with a twin-slot antenna designed to couple to 160-GHz radiation through a silicon lens.The first device has a highly doped silicon absorber, the second has a highly doped strained-silicon absorber.Using a novel method of cross-correlating the outputs from two parallel amplifiers, we measure noise-equivalent powers of $3.0 \times 10^{-16}$ and $6.6 \times 10^{-17}~\mathrm{W\,Hz^{-1/2}}$ for the control and strained device, respectively, when observing radiation from a 77-K source. In the case of the strained device, the noise-equivalent power is limited by the photon noise.

description: We study perturbative general relativity with a two-form and a dilaton using the double field theory formulation which features explicit index factorisation at the Lagrangian level. Explicit checks to known tree level results are performed. In a natural covariant gauge a ghost-like scalar which contributes even at tree level is shown to decouple consistently as required by perturbative unitarity. In addition, a lightcone gauge is explored which bypasses the problem altogether. Using this gauge to study BCFW on-shell recursion, we can show that most of the D-dimensional tree level S-matrix of the theory, including all pure graviton scattering amplitudes, is reproduced by the double field theory. More generally, we argue that the integrand may be reconstructed from its single cuts and provide limited evidence for off-shell cancellations in the Feynman graphs. As a straightforward application of the developed technology double field theory-like expressions for four field string corrections are derived.

description: Purpose To meet the increasing demands of total shoulder arthroplasty (TSA) while reducing its financial burden, there has been a shift toward outpatient surgery. This systematic review and meta-analysis aimed to evaluate the safety of outpatient TSA. Methods The primary objective was to compare re-admission rates and postoperative complications in outpatient versus inpatient TSA. The secondary objectives were functional outcomes and costs. PubMed, Google Scholar, and Web of Science were searched until March 28, 2020. The inclusion criteria were studies reporting at least complications or readmission rates within a period of 30 days or more. Results Ten level III retrospective studies were included with 7637 (3.8%) and 192,025 (96.2%) patients underwent outpatient and inpatient TSA, respectively. Outpatient TSA had relatively younger and healthier patients. There were no differences between outpatient and inpatient arthroplasty for 30- and 90-day readmissions. Furthermore, unadjusted comparisons demonstrated significantly less total and major surgical complications, less total, major, and minor medical complications in favour of outpatient TSA. However, subgroup analyses demonstrated that there were no significant differences in all complication if the studies had matched controls and regardless of data source (database or nondatabase studies). The revision rates were similar between both groups at a 12–24 months follow-up. Two studies reported a significant reduction in costs in favour of outpatient TSA. Conclusion This study highlights that outpatient TSA could be a safe and effective alternative to inpatient TSA in appropriately selected patients. It was evident that outpatient TSA does not lead to increased readmissions, complications, or revision rates. A potential additional benefit of outpatient TSA was cost reduction.Other Information Published in: International Orthopaedics
