Published: June 2019

Amorphous metal-oxide semiconductors (AOSs) such as indium-gallium-zinc-oxide (IGZO) as an active channel have attracted substantial interests with regard to high-performance thin-film transistors (TFTs). Recently, intensive and extensive studies of flexible and/or wearable AOS-based TFTs fabricated by solution-process have been reported for emerging approaches based on device configuration and fabrication process. However, several challenges pertaining to practical and effective solution-process technologies remain to be resolved before low-power consuming AOS-based TFTs for wearable electronics can be realized. In this paper, we investigate the non-thermal annealing processes for sol-gel based metal-oxide semiconductor and dielectric films fabricated by deep ultraviolet (DUV) photo and microwave annealing at low temperature, compared to the conventional thermal annealing at high temperature. A comprehensive investigation including a comparative analysis of the effects of DUV photo and microwave annealing on the degree of metal-oxide-metal networks in amorphous IGZO and high-dielectric-constant (high-k) aluminum oxide (Al2O3) films and device performance of IGZO-TFTs in a comparison with conventional thermal annealing at 400 °C was conducted. We also demonstrate the feasibility of wearable IGZO-TFTs with Al2O3 dielectrics on solution-processed polyimide films exhibiting a high on/off current ratio of 5 × 104 and field effect mobility up to 1.5 cm2/V-s operating at 1 V. In order to reduce the health risk and power consumption during the operation of wearable electronics, the operating voltage of IGZO-TFTs fabricated by non-thermal annealing at low temperature was set below ~1 V. The mechanical stability of wearable IGZO-TFTs fabricated by an all-solution-process except metal electrodes, against cyclic bending tests with diverse radius of curvatures in real-time was investigated. Highly stable and robust flexible IGZO-TFTs without passivation films were achieved even under continuous flexing with a curvature radius of 12 mm.
The social dynamics of lung cancer talk on Twitter, Facebook and Macmillan.org.uk
Authors: Taylor Joanna , Pagliari Claudia
Published: June 2019

People with lung cancer and others affected by the condition are using social media to share information and support, but little is known about how these behaviours vary between different platforms. To investigate this, we extracted posts from Twitter (using relevant hashtags), the Lung Cancer Support Group on Facebook and the Macmillan.org.uk lung cancer discussion forum for a single month. Interaction Process Analysis revealed that all three platforms were used more for giving than seeking information, opinion or suggestions. However, interaction types (including sentiment) varied between platforms, reflecting their digital architectures, user-base and inclusion of a moderator. For example, a higher percentage of information-seeking and sentiment marked the Macmillan.org.uk, compared with Twitter and the Facebook Group. Further analysis of the messages using a four-dimensional typology of social support revealed that emotional and informational support types were most prevalent on the Macmillan.org.uk forum, closely followed by the Facebook Group. Contrary to expectations, Twitter posts showed the most companionship support, reflecting the use of hashtags as user-generated signals of community belonging and interests. Qualitative analysis revealed an unanticipated sub-category of spiritual support, which featured uniquely in the Lung Cancer Support Group on Facebook. There was little evidence of trolling or stigma, although some users remarked that lung cancer was unfairly resourced compared with other cancers. These findings provide new insights about how people affected by lung cancer use social media and begin to elucidate the value of different platforms as channels for patient engagement and support, or as potential research data sources.

Test–Retest Reliability of Relative Fundamental Frequency and Conventional Acoustic, Aerodynamic, and Perceptual Measures in Individuals With Healthy Voices
Authors: Park Yeonggwang , Stepp Cara E.
Published: June 2019

Purpose

Recent studies have shown that an acoustic measure, relative fundamental frequency (RFF), has potential for the assessment of excessive laryngeal tension and vocal effort associated with functional and neurological voice disorders. This study presents an analysis of the test–retest reliability of RFF in individuals with healthy voices and a comparison of reliability between RFF and conventional measures of voice.

Method

Acoustic and aerodynamic measurements and Consensus Auditory–Perceptual Evaluation of Voice (CAPE-V) were performed on 28 individuals with healthy voices on 5 consecutive days. Participants produced RFF stimuli, a sustained /ɑ/, and a reading passage to allow for extraction of acoustic measures and CAPE-V ratings; /pa/ trains were produced to allow for extraction of aerodynamic measures.

Results

Moderate reliabilities (intraclass correlation coefficient [ICC] = .64–.71) were found for RFF values. Mean vocal fundamental frequency, smoothed cepstral peak prominence, shimmer, harmonics-to-noise ratio, and mean airflow rate exhibited good-to-excellent reliabilities (ICC = .76–.99). ICCs for jitter and phonation threshold pressure were moderately reliable (ICC = .67–.74). ICCs for subglottal pressure estimates and all CAPE-V parameters showed poor reliabilities (ICC = .31–.58).

Conclusion

RFF has comparable reliability to conventional measures of voice. This expands the potential for clinical application of RFF.

Optimisation framework for the operation of battery storage within solar‐rich microgrids
Authors: Jayawardana Asanga , Agalgaonkar Ashish P. , Robinson Duane A. , Fiorentini Massimo
Published: June 2019

The growing trend of distributed generation, such as solar photovoltaic (PV) systems and small scale wind turbines have promoted the development of microgrids which are highly dependent on renewable energy. Due to the intermittent nature of renewable energy, these microgrids are generally equipped with energy storage, such as batteries. Batteries are generally operated using fixed control methods, often deviating from the optimal operation. This aspect has created an opportunity to gain improved outcomes for microgrid owners and operators. This research study describes a pathway for designing an optimisation framework which can be used to optimise the charge and discharge operation of battery storage within a microgrid containing a solar PV system. Optimisation is implemented in terms of gaining maximum cost benefit for microgrid owners. The advantages of using model predictive control optimisation compared to fixed control methods for this particular problem, solvers and verification procedures are highlighted. A case study is provided with results including analysis of battery operation, energy usage, and impact on overall tariff. The study describes each step of the control and optimisation platform development ensuring readers to be able to replicate the process utilised.
Reflection geometries in absorbed and unabsorbed AGN
Authors: Panagiotou C. , Walter R.
Published: June 2019

Context. The hard X-ray emission of active galactic nuclei (AGN), and in particular, the reflection component, is shaped by the innermost and outer regions of the galactic nucleus.

Aims. Our main goal is to investigate the variation of the Compton hump amongst a population of sources and correlate it with other spectral properties to constrain the source geometry.

Methods. We studied the NuSTAR hard X-ray spectra of a sample of 83 AGN and performed a detailed spectral analysis of each of them. Based on their spectral shape, we divided the sample into five categories and also studied their stacked spectra.

Results. We found a stronger reflection in mildly obscured sources, which verifies the results reported in previous works. In addition, the reflection behaviour, and probably origin, varies with absorption. The accretion disc seems to be the main reflector in unabsorbed sources. A clumpy torus seems to produce most of the reflection in obscured sources. The filling factor of the clouds surrounding the active nucleus is a key parameter that drives the appearance of AGN. Finally, we found that the Fe line and the Compton hump are roughly correlated, as expected.

Published: June 2019

The results of studies on improving the environmental characteristics of boiler plants of municipal heat-power engineering in the application of technologies for the deep recovery of heat from exhaust-gases of gas-fired boilers are presented. The data on the reduction of environment by reducing the amount and temperature of harmful emissions resulting from fuel combustion are given. The data are given for boiler plants equipped with complex heat-recovery systems characterized by cooling the exhaust-gases below the dew point of the water vapor contained in them. It is shown that the decrease in emissions is due to a decrease in fuel consumption in boilers due to the beneficial use of the heat of exhaust-gases in these systems and the dissolution of nitrogen and carbon oxides in the condensate, formed in the heat-recovery equipments. The analysis of improving the environmental safety of boiler plants when used in heat-recovery technologies of corrosion protection systems for chimneys has been performed. Anticorrosion protection is provided by preventing condensate formation in the exhaust-gas ducts of boiler plants when using technologies for the deep recovery of exhaust-gas heat. To prevent condensate formation, the method of pre-drying cooled exhaust-gases in a heat exchanger-preheater installed after heat-recovery equipment is used. It is also shown that the use of complex heat-recovery systems provides in the boiler plant additional water in the form of condensate formed during condensation of moisture from exhaust-gases. Receipt of this condensate is another ecological effect of heat-recovery, which allows reducing the consumption of natural water resources for supply municipal heat networks.
Performance of special type heat sink with an integrated synthetic jet actuator
Authors: Gil Paweł
Published: June 2019

The performance of special type heat sink with integrated synthetic jet actuator has been presented in this work. Synthetic jet is a flow technique which synthesizes stagnant air to a form of jet. Synthetic jet produces high turbulent flow and thus high heat transfer coefficient can be achieved. Standard heat sink with fan have limited applications in particular in a dusty industrial environment. Therefore, the use of new flow technique is optimistic. The paper presents preliminary results of heat sink thermal power and characteristic temperatures during synthetic jet switched on and off. The results show that under synthetic jet switched on, the dissipated heat is 3.7 times higher than when synthetic jet is switched off.

Published: June 2019

The issue of waste accumulation has become one of the global problems of humanity. In Ukraine, the main method of waste management is landfill depositing, which is unproductive and affects the ecosystem negatively. However, large landfill sites should be used to produce biogas, thereby reducing the environmental burden and the earned revenue should be used to introduce recycling and a gradual transition to a European waste management policy. The aim of our study was to investigate the state of waste recycling and the possibility of using waste landfills and food with lost consumptive qualities for biogas generation. To analyze the economic efficiency of the installation of biogas equipment in landfills and to investigate the current state of waste management in Ukraine. The research demonstrates that at present in Ukraine the problem of waste accumulation becomes actual. At the same time, the number of large waste landfills is increasing. It is proved that at landfills with an area of more than 50 hectares, the installation of biogas equipment is cost-effective, and the raw material can be distributed at the feed-in tariff, thus solving the energy problem.

Authors: Kwarciak-Kozłowska Anna , Włodarczyk Renata , Wystalska Katarzyna
Published: June 2019

The aim of the research was to compare the effectiveness of sorption of pollutants from landfill leachate on two granulated activated carbons (AG and BA-10) and biochar (BC). The sorption process of wastewater components on activated carbons was carried out under static conditions for 72 hours. The doses of adsorbents used varied from 2–8 g·dm-3. Results of removing of COD were estimated on the base of adsorption capacity and COD removal efficiency. After 72 h of the process at the highest doses (8 g·dm-3), the COD removal rate ranged from 40% (BA-10) to 60% (AG). In the case of biochar, the COD adsorption rate was 53% The state of sorption equilibrium takes a similar character for BC and AG and is determined after 4 h. The degree of sorption of selected metals from landfill leachate using the analyzed range ranged from 84% to 96% depending on its type.

Authors: Lis Anna , Spodyniuk Nadiia
Published: June 2019

Realization and exploitation of buildings involves in European Union about 40% of total energy consumption [1]. One of the elements of rationalization of energy consumption in buildings are the undertakings related with thermal modernization of buildings. The actions related with reducing the energy intensity of buildings are not always correlated with improvement of microclimate conditions in the rooms. Errors in the implementation of the energy efficiency program led to the phenomenon of sick building syndrome. The paper presents the results of the research conducted in a few educational buildings before and after thermal modernization. The research includes energy consumption for the heating of building and selected parameters of the interior microclimate. This analysis was carried out to evaluate the influence of energy saving activities on microclimate interior conditions. It was found that in many cases commonly used gravitational ventilation is not able to ensure the proper conditions of the interior microclimate, and the concentrations of carbon dioxide recorded in the tested rooms exceeded the applicable standards.

Authors: Stefanowicz Ewelina , Szulgowska-Zgrzywa Małgorzata
Published: June 2019

The negative impact of systems based on fossil fuel on the environment and the desire to promote sustainable development is increasingly encouraging building owners to invest in renewable energy sources. One of the possibilities of using a renewable energy source located in shallow soil layers is a brine-to-water heat pump. Ground energy can be used for both heating and cooling buildings. This article presents the advantages of balancing the supply and energy consumption from the ground for the large heat pump systems. Authors presented a case study and the simulation of the system operation with different cooling load share vs heating load. This was done on the basis of the analysis of data from several years of measurements from the actual installation as well as the simulation in Earth Energy Designer software. The results of the simulations shows that the most advantageous strategy for the operation of the analysed installation is to provide 50 to 75% of the cooling load in relation to the heating load.
Risk analysis associated with secondary water pollution in selected agglomerations of the Silesian Voivodship
Authors: Zimoch Izabela , Bartkiewicz Ewelina
Published: June 2019

Water quality is the most important parameter related to water intended for human consumption. The main task of water supply companies is to keep water quality at the possible highest level. Water, which consumers receive in their homes, is the final product of a multi-stage processing, which aims to obtain water with the required physico-chemical and biological composition. Nevertheless, during transport through the Water Supply System (WSS), water reacts with various factors, sometimes causing secondary pollution. An important threat associated with water quality reduction is disinfection by-products (DBP), formed during the oxidation of organic compounds and some inorganic compounds found in water. DBPs has carcinogenic properties, that’s why they are threats for human health.The article presents the results of water quality analysis and risk assessments. In research the real WSS, which supplies water to selected Silesian agglomeration, was analyzed. The work uses laboratory tests of selected water parameters. Statistical methods were used to determine the causes of water quality deterioration.
Psychokardiologie – aktuelle Leitlinien und klinische Realität
Authors: Herrmann-Lingen Christoph
Published: June 2019

In the last decades, psychocardiological knowledge has contributed a lot to the understanding of psychosocial factors involved in the pathogenesis, course, and treatment of cardiovascular diseases. Therefore, psychological, social, and behavioral factors should be detected and addressed early on in order to prevent cardiovascular disease and/or its progression. On the other hand, cardiovascular disease is an important stressor which can lead to psychological comorbidities and thus deteriorate prognosis and quality of life. During therapy a clear, consistent, and empathic communication between professionals and patients is of importance. Up to now there is not much evidence as to the effectiveness of psychotherapeutic interventions or antidepressant medication for cardiac patients with mental comorbidities. Beyond psychosomatic basic care, combined with physical activity, severely ill patients may require multimodal inpatient care in specialized psychosomatic or psychocardiological units and continuous support with lifestyle change.

Authors: Miehlke Stephan , von Arnim Ulrike , Schlag Christoph , Frieling Thomas , Madisch Ahmed , Loibl Rudolf , Mainz Dagmar , Labenz Joachim
Published: June 2019

Background Eosinophilic esophagitis (EoE) is an increasingly recognized immune-mediated esophageal disease and a common cause for dysphagia and food bolus obstruction. The aim of this study was to evaluate the current clinical management of EoE among adult gastroenterologists in Germany.

Methods We performed a cross-sectional study of 1393 adult gastroenterologists using a questionnaire containing 22 questions to general, diagnostic, and therapeutic aspects of EoE. The self-administered online survey was conducted between November 2017 and February 2018. Data capture and analysis was performed using SurveyMonkey.

Results The overall responder rate was 29.6 %. More than half of the responders (54.9 %) felt to observe a significant increase of EoE patients. The EREFS score was mostly either unknown (44.3 %) or not routinely used (52.2 %). If EoE was suspected, most responders obtained multiple esophageal biopsies (n = 3 – 4: 35.7 %; n > 4: 61.6 %). The preferred primary treatment was proton pump inhibitors (PPI) in 37.2 % and topical steroids in 35.0 % of responders. PPI regimens were highly diverse, with only half of responders using high-dose PPI regimens. Allergy testing was often initiated (always 25.4 %, sometimes 48.9 %). The most common dietary therapy was 6-food elimination diet (52 %), followed by allergy test-directed diets (16 %) and 2-food elimination diet (16.5 %). The majority of responders indicated a need for long-term treatment (i. e., 23 % of responders in > 50 % their patients and 47.7 % of responders in 25 – 50 % of their patients).

Conclusions Among gastroenterologists in Germany, substantial variation in the adherence to published EoE guidelines appears to exist. This indicates the need for intensified education and national guidelines in order to optimize and harmonize the clinical management of EoE patients.
Zum Problem der Häufigkeitsbestimmung von
Intergeschlechtlichkeit und Varianten der Geschlechtsentwicklung: Eine
Übersichtsarbeit
Authors: Hauck Lena , Richter-Appelt Hertha , Schweizer Katinka
Published: June 2019

Einführung Körperliche Geschlechtsentwicklungen, die auf chromosomaler,
gonadaler und/oder anatomischer Ebene untypisch verlaufen, werden als
Intergeschlechtlichkeit, Varianten der Geschlechtsentwicklung, Intersex,
Intersexualität, Variationen der körpergeschlechtlichen Merkmale und Störungen
der Geschlechtsentwicklung bezeichnet. Sie sind alternative Oberbegriffe für
eine Reihe verschiedener Besonderheiten der somatosexuellen Entwicklung, für die
in der Literatur unterschiedliche Angaben über deren Häufigkeiten kursieren.

Forschungsziele Der Beitrag präsentiert eine Übersicht über aktuelle
Angaben zur Häufigkeit und identifiziert Faktoren, welche die Festlegung einer
Zahl zur Inzidenz bzw. Prävalenz von Varianten der Geschlechtsentwicklung
erschweren.

Methoden Es wurde eine Literaturrecherche in den Datenbanken
Medline, Web of Science und PsycINFO durchgeführt.
Dabei wurden englisch- und deutschsprachige Studien von 2000 bis 2017 erfasst,
die sich mit der Inzidenz von Varianten der körpergeschlechtlichen Entwicklung
beschäftigen. Aus den Ergebnissen wurden relevante Treffer ausgewählt, anhand
derer aktuelle Zahlen zur Häufigkeit, unterschiedliche Methoden der
Häufigkeitserhebung sowie Probleme bei der Ermittlung der Zahlen
herausgearbeitet wurden.

Ergebnisse Die analysierten Studien geben Zahlen zwischen 0.018 % und 2.1
% bzw. 3.8 % aller Geburten als Gesamthäufigkeit von Varianten der
Geschlechtsentwicklung bzw. des urogenitalen Systems an. Diese hängen stark von
der Definition und den eingeschlossenen Formen ab. Die Seltenheit einiger Formen
und die kritikwürdigen Untersuchungsmethoden erschweren die Erhebung belastbarer
Ergebnisse.

Schlussfolgerung In der Forschung zur Intergeschlechtlichkeit sollte eine
transparente, respekvolle und präzise Sprache als Grundlage für einen
konstruktiven Diskurs über geschlechtliche Vielfalt eingesetzt werden, auch um
Kooperationsprojekte zu stärken. Die angenommene Dunkelziffer der nicht
erfassten oder diagnostizierten Fälle sollte nicht unterschätzt werden.

Frühgeborene haben ein erhöhtes Risiko, einen Zinkmangel zu erleiden, da bedingt durch die fehlende intrauterine Reifung die Zinkspeicher in der Leber nicht gefüllt werden können. Bei einem eutrophen weiblichen Frühgeborenen von 25+5 Schwangerschaftswochen zeigten sich ab dem 14. Lebenstag ein perinealer und perianaler „Dekubitus“. Zahlreiche lokale Therapieversuche blieben erfolglos. Die Diagnostik erbrachte einen erniedrigten Serum-Zinkspiegel, sodass mit einer Substitution begonnen wurde. Bereits nach wenigen Tagen begannen die Defekte zu heilen und waren nach drei Wochen vollständig abgeheilt. Trotz regulären Nahrungsaufbaus mit Formula-Nahrung war der Zinkbedarf in diesem Fall vermutlich aufgrund unvollständiger Resorption nicht gedeckt worden. Der Fall macht auf eine latente Unterversorgung von Frühgeborenen mit Zink aufmerksam und unterstreicht die Notwendigkeit von Kontrollen, besonders bei entsprechenden Hautsymptomen.

Objective The objective of this study is to compare the implant stability of Hiossen ET III implants with its new hydrophilic (NH) surface and Hiossen ET III implants with the sandblasted and acid-etched (SA) surface.

Materials and Methods Patients required at least two teeth to be rehabilitated with a fixed, implant-supported restoration, consecutively enrolled. Patients randomly received SA surface implants (SA group) or SA implants with a newly developed bioabsorbable apatite nanocoating (NH group). Outcome measures were implant and prosthetic survival rate, complications, insertion torque, and implant stability quotient (ISQ) measured at implant placement and every week up to 8 weeks after implant placement. Comparison between groups was made by unpaired t-test, while the comparison between each follow-up will be made by paired t-tests to detect any change during the follow-up. Complications and failures were compared using Fisher's exact test.

Results A total of 14 patients were treated with 28 implants (14 SA and 14 NH). No implant and prosthesis failed 4 months after implant placement. No complications were experienced. At the 2nd week after implants placement, two implants in the SA group showed discontinuous measurements versus none in the NH group (p = 0.4815). Implants unscrewed during ISQ measurements and were rescrewed. Data recording stopped for 6 weeks. Both implants osseointegrated without any further complication. The NH implants did not show physiological ISQ decrease between 2nd and 4th week after implant placement, showing a more even pattern of ISQ values compared with SA implants (77.1 ± 4.6 vs. 72.9 ± 11.5; difference: 4.2 ± 12.1; p = 0.258). High ISQ values were found in both groups at each time point.

Conclusions NH implants are a viable alternative to SA surface, as they seem to avoid the ISQ drop during the remodeling phase.

Objective This study was carried out to assess and compare the marginal gap of conventionally used metal onlays and new resin nanoceramic (RNC) (Lava Ultimate block) onlays.

Materials and Methods This is an in vitro study using two extracted sound human mandibular molars. One tooth was prepared to receive the metal onlays and another one for the RNC onlays which were fabricated using the computer-aided design and computer-aided manufacturing (CAD/CAM) technology. Twelve metals and 12 ceramic onlays were fabricated before they were placed at their respective preparation and examined under the Leica stereomicroscope, M125C (Leica Microsystems, Wetzlar, Germany) for a marginal analysis. The gap width was measured at 10 predefined landmarks which included 3 points on the buccal and lingual surfaces each and 2 points each on the mesial and distal surfaces, respectively.

Statistical Analysis Mann–Whitney post hoc test was used for statistical analysis (P ≤ 0.05).

Results Overall, the RNC onlays showed significant lower marginal gap with the exception of the landmarks 5 and 6 (on distolingual) and no significant difference at landmark 7 (on midlingual). It was observed that the marginal gap were all within the clinically acceptable limit of 120 μm.

Conclusions Based on the results obtained, it can be concluded that the RNC CAD/CAM onlays are a promising alternative to the metal onlays.

Introduction The Prune Belly Syndrome (PBS) is the deficiency or congenital hypoplasia of the abdominal muscles accompanied with disorders of the urinary tract. The surgical treatment for the uropathy of the PBS seeks to correct the anatomical defects that induce damage to the urinary tract, including the improvement of the bladder emptying. The correction of the abdominal wall defect must be considered as an important part of the treatment.

Objective To describe of the most relevant clinic characteristics and outcomes of a group of eight patients with PBS managed with abdominoplasty and reconstructive urologic surgery.

Methods Retrospective review of the medical charts of patients with PBS at Hospital Universitario San Ignacio, Hospital Militar Central of Bogotá, Clinica Infantil Colsubsidio and Fundación Oftalmológica Ardila Lulle of Bucaramanga, (Colombia) that were managed with reconstructive surgery of the urinary tract and Monfort technique abdominoplasty (between 2006 and 2016) by one of the authors (JPN). The evaluated variables included: phenotypic appearance, renal function, bowel movements, and urinary tract infection (UTI) episodes. These variables as well as the abdominal wall aspect, were evaluated postoperatively.

Results There were 11 patients identified with PBS between 2006 and 2016. Eight (8) of them underwent reconstructive urologic surgery, orchidopexy and Monfort technique abdominoplasty. After the procedures, none of the patients presented deterioration of the renal function, and they reported a better quality of the stools according to the Bristol scale; there were also less episodes of UTI. The phenotypic aspect of the abdominal wall was qualified as satisfactory in all cases.

Conclusions Reconstructive urologic surgery and abdominoplasty in patients with PBS is an excellent choice of management that reduces the number of UTIs, improves bowel movements according to the Bristol scale, and preserves the renal function. This management approach also improves the phenotypic aspect of the abdominal wall. All of this leads to higher survival rate and better quality of life.

The development of a superconducting analog to the transistor with extremely low power dissipation will accelerate the proliferation of low-temperature circuitry operating in the milliKelvin regime. The thin-film, magnetically actuated cryotron switch is a candidate building block for more complicated and flexible milliKelvin circuitry. We demonstrate its utility for implementing reconfigurable circuitry by integrating a cryotron switch into flux-summed code-division SQUID multiplexed readout for large arrays of transition-edge-sensor (TES) microcalorimeters. Code-division multiplexing eliminates the noise penalty of time-division multiplexing while being drop-in compatible with the latter's control electronics. However, code-division multiplexing is susceptible to single-point failure mechanisms which can result in an unconstrained demodulation matrix and the loss of information from many sensing elements. In the event of a failure, the integrated cryotron switch provides a zero-signal output from a single TES, enabling the demodulation matrix used to compute TES signals from SQUID signals to be constrained and data recovered from the remaining sensors. This demonstration of configurable error correction provides both a real-world application of the cryotron switch and a foundation for more complex circuitry at milliKelvin temperatures.
