Treatment of Acid Hydrolysis of a 1900 Large-Scale Composite Artwork by the Artist Roberto Sebastian Matta: Comparison between Traditional and Innovative Deacidifying Methodologies
Authors: Partenzi Ilaria , Marconi Martina , Vinciguerra Vittorio , Pelosi Claudia , Fontani Nicoletta
Published: March 2023

This work was carried out for a master’s degree thesis concerning the conservation of a contemporary artwork made by the surrealist artist Roberto Sebastian Matta. The artwork is a large (one central panel 180.3 × 405.1 cm; two side panels 179.1 × 150.6 cm) triptych created in 1974 with pastels on tracing paper adhered onto canvas as a secondary support. After thoroughly studying the execution technique and conservation status of the artwork, several issues arose, including a strong acid hydrolysis of both the paper and canvas supports. We focused our intervention on deacidification treatments by comparing either traditional substances, such as calcium propionate in an alcoholic solution, or more innovative methods, such as a nanostructured calcium hydroxide in isopropyl alcoholic solution. Acid hydrolysis degradation was the most difficult issue to address because of the size of the artwork and for the different sensitivities to aqueous methods of the materials used to make the artwork. For the first time to our knowledge, we used an innovative deacidification method consisting of nanostructured calcium hydroxide particles. This intervention would allow the homogeneous atomization of the deacidifying agent in alcoholic solvents to be safe and effective for the work as a whole.
ReMouse Dataset: On the Efficacy of Measuring the Similarity of Human-Generated Trajectories for the Detection of Session-Replay Bots
Authors: Sadeghpour Shadi , Vlajic Natalija
Published: March 2023

Session-replay bots are believed to be the latest and most sophisticated generation of web bots, and they are also very difficult to defend against. Combating session-replay bots is particularly challenging in online domains that are repeatedly visited by the same genuine human user(s) in the same or similar ways—such as news, banking or gaming sites. In such domains, it is difficult to determine whether two look-alike sessions are produced by the same human user or if these sessions are just bot-generated session replays. Unfortunately, to date, only a handful of research studies have looked at the problem of session-replay bots, with many related questions still waiting to be addressed. The main contributions of this paper are two-fold: (1) We introduce and provide to the public a novel real-world mouse dynamics dataset named ReMouse. The ReMouse dataset is collected in a guided environment, and, unlike other publicly available mouse dynamics datasets, it contains repeat sessions generated by the same human user(s). As such, the ReMouse dataset is the first of its kind and is of particular relevance for studies on the development of effective defenses against session-replay bots. (2) Our own analysis of ReMouse dataset using statistical and advanced ML-based methods (including deep and unsupervised neural learning) shows that two different human users cannot generate the same or similar-looking sessions when performing the same or a similar online task; furthermore, even the (repeat) sessions generated by the same human user are sufficiently distinguishable from one another.
Adaptive Immunosuppression in Lung Transplant Recipients Applying Complementary Biomarkers: The Zurich Protocol
Authors: Schuurmans Macé M. , Raeber Miro E. , Roeder Maurice , Hage René
Published: March 2023

Achieving adequate immunosuppression for lung transplant recipients in the first year after lung transplantation is a key challenge. Prophylaxis of allograft rejection must be balanced with the adverse events associated with immunosuppressive drugs, for example infection, renal failure, and diabetes. A triple immunosuppressive combination is standard, including a steroid, a calcineurin inhibitor, and an antiproliferative compound beginning with the highest levels of immunosuppression and a subsequent tapering of the dose, usually guided by therapeutic drug monitoring and considering clinical results, bronchoscopy sampling results, and additional biomarkers such as serum viral replication or donor-specific antibodies. Balancing the net immunosuppression level required to prevent rejection without overly increasing the risk of infection and other complications during the tapering phase is not well standardized and requires repeated assessments for dose-adjustments. In our adaptive immunosuppression approach, we additionally consider results from the white blood cell counts, in particular lymphocytes and eosinophils, as biomarkers for monitoring the level of immunosuppression and additionally use them as therapeutic targets to fine-tune the immunosuppressive strategy over time. The concept and its rationale are outlined, and areas of future research mentioned.

Background and objectives: In patients with colorectal cancer (CRC), heterogeneous expression of Mismatch repair (MMR) proteins can manifest itself in several different forms and is not such a rare phenomenon. Therefore, it is very important to recognize the nuclear expression of MMR proteins of different MMR status in order to avoid false positive or false negative results. The aim of this study was to determine the frequency and distribution of heterogeneous expression of MMR proteins in patients with stages II and III of the disease as well as its association with clinical, demographic and pathological characteristics of CRC in relation to proficient and deficient expression of MMR proteins. Material and Methods: The study included 104 cases of colorectal cancer obtained from surgical colectomy material in stages II and III of the disease. Results: From a total of 104 patients with colorectal cancer, immunohistochemical analysis of the expression of all four MMR proteins showed that heterogeneous expression of MMR proteins (as well as deficient immunoreactivity of tumor cells) was present in 12 cases, while proficient expression of MMR proteins was detected in 80 tumors. Conclusions: Our study showed that the only independent predictors of the loss of MMR protein expression were younger patient age and right-sided anatomical location of the tumor. The study also established the existence of heterogeneous expression of MMR proteins in a non-negligible percentage of CRCs (11.5%), where heterogeneous nuclear expression of MMR proteins was described in several different forms.
The Ontology of the Many-Worlds Theory

It is shown that the wavefunction describes our observations using the postulate that relates position to the distribution |Ψ|2. This finding implies that a primary ontology is unnecessary. However, what is real is not directly represented by the wavefunction but by the gauge invariants. In light of the presented ontology, Spacetime State Realism becomes not a fundamental ontology but derived.

Authors: Li Hang , Jiang Huiming
Published: March 2023

Based on the County-Level Digital Rural Index and county-level panel data for Jilin Province (2018–2020), this study used a fixed-effect model to investigate the effect of the digital economy on Chinese farmers’ income. The results show that the digital economy can positively affect farmers’ disposable income and that there is regional heterogeneity. Specifically, digital economy development has better effects on farmers’ income in the eastern region of Jilin Province, but there is still room for development in the central and western regions. Accordingly, from the perspectives of urbanization, industrial structure, government support for agriculture, digital-inclusive finance, and agricultural digital talent, suggestions have been made to promote the coordinated development of the digital economy and farmers’ livelihoods in various regions.

We aimed to determine the prevalence of bacterial coinfection (CoBact) and bacterial superinfection (SuperBact), the causative pathogens, the initial antibiotic-prescribing practice, and the associated clinical outcomes of hospitalized patients with respiratory syncytial virus-associated acute respiratory illness (RSV-ARI). This retrospective study included 175 adults with RSV-ARI, virologically confirmed via RT-PCR, during the period 2014–2019. Thirty (17.1%) patients had CoBact, and 18 (10.3%) had SuperBact. The independent factors associated with CoBact were invasive mechanical ventilation (OR: 12.1, 95% CI: 4.7–31.4; p < 0.001) and neutrophilia (OR: 3.3, 95% CI: 1.3–8.5; p = 0.01). The independent factors associated with SuperBact were invasive mechanical ventilation (aHR: 7.2, 95% CI: 2.4–21.1; p < 0.001) and systemic corticosteroids (aHR: 3.1, 95% CI: 1.2–8.1; p = 0.02). CoBact was associated with higher mortality compared to patients without CoBact (16.7% vs. 5.5%, p = 0.05). Similarly, SuperBact was associated with higher mortality compared to patients without SuperBact (38.9% vs. 3.8%, p < 0.001). The most common CoBact pathogen identified was Pseudomonas aeruginosa (30%), followed by Staphylococcus aureus (23.3%). The most common SuperBact pathogen identified was Acinetobacter spp. (44.4%), followed by ESBL-positive Enterobacteriaceae (33.3%). Twenty-two (100%) pathogens were potentially drug-resistant bacteria. In patients without CoBact, there was no difference in mortality between patients who received an initial antibiotic treatment of <5 days or ≥5 days.

Published: March 2023

Transmission loss is a very important acoustic characteristic of the muffler. In order to improve the efficiency of the double-load method for measuring the transmission loss of the muffler, this paper proposes a single-step measurement method for transmission loss of muffler. In addition,
the simulation model of the single-step measurement method is established based on the finite element acoustic analysis. For the model, the calculation method of the transmission loss of the muffler is deduced from the theoretical knowledge of the transfer matrix. In the simulation, the sound
pressure data of six positions in the model are obtained, and the transfer matrix is used to calculate the transmission loss of the muffler. Then, two simulation comparison experiments were done. In order to verify the validity of the single-step measurement method, the first comparison experiment
was to compare the transmission loss of the muffler simulated by the single-step measurement method with their theoretical transmission loss in the finite element acoustic analysis. The results of the simulation validation test cases showed that the transmission loss of the muffler obtained
by the single-step measurement method was consistent with the theoretical value. The second comparison experiment was to compare the transmission loss obtained by the single-step measurement method with the transmission loss obtained by the double-load method. The results of the simulation
validation test cases showed that at certain frequencies, the transmission loss obtained by the single-step measurement method was more accurate than the transmission loss obtained by the double-load method. In conclusion, the single-step measurement method proposed in this paper can accurately
obtain the transmission loss of the muffler with only one measurement, which improves the measurement efficiency.
Experimental contribution analysis of external noise components to interior noise of an automobileExperimental contribution analysis of external noise components to interior noise of an automobile

Published: March 2023

The contribution analysis of various automobile noise sources to the interior noise is important, enabling to design an automobile with a low interior noise level. However, it is difficult to experimentally analyze the contribution of physically meaningful noise sources to the interior
noise using the state-of-the-art contribution analysis method, for example, based on the transmissibility matrix method and the singular value decomposition (SVD), since the source strengths decomposed by using the SVD procedure are difficult to be associated with physical sources. Here, it
is proposed to decompose an interior noise auto-spectrum into multiple auto-spectra, each represents the contribution of a physically meaningful noise source to the interior noise, by using the LDL decomposition. Through an experiment with the three speakers driven by three independent, filtered
random noise signals, it was shown that the measured noise spectrum could be successfully decomposed into three contributions, each associated with noise radiated from only one speaker. Then, an automobile instrumented with 64 exterior and 4 interior microphones was tested on a highway at
the speeds of 65 miles per hour (mph) and 80 mph. The contribution results obtained by processing the measured microphone signals indicated the highest contributions of the aeroacoustic sources on the windows and the hood to the interior noise.
Design and validation of micro-vibration isolator for reaction wheels in consideration of launch environment of satellite
Authors: Huang Jie , Yu Z.F.
Published: March 2023

Micro-vibration is an important factor that influences the imager orientation accu- racy and even deteriorates the quality of image of high-resolution satellite. To eliminate the influences of micro-vibration, a passive micro-vibration isolation method is proposed for reaction wheels
(RWs) of satellite. At the same time, the launch environment is fully considered in the design of isolation system to guarantee the safety of both RWs. The isolation efficiency and orientation stability experiment results show that, without isolators, the peak value of the torque output reaches
more than 10 Nm that is sharply depressed with isolation system operating mode. Without isolators, four clear peak values located at 10 Hz, 41 Hz, 47 Hz, 83 Hz are found in the orientation oscillation of RW. The random vibration experiments show that the maximal acceleration output 34.61 g
is much lower than the RW design value 49 g which guarantees the safety of RW under harsh launch environment. The isolating efficiency is higher than 75% which is suitable for the requirement of the imager on-board the SDLT-1 satellite.

This study aims to determine the authority of notaries and Land Deed Making Officials (PPAT) in making a concession agreement deed due to a lost mortgage certificate, analyzing the stages and processes in registering a concession agreement deed due to a lost mortgage certificate at the Asahan Regency Land Office and assessing the position law and the use of a concession agreement deed due to a lost mortgage certificate at the Asahan Regency Land Office. This study uses a qualitative descriptive method with a case approach and a statutory approach. The results of the study indicate that the Royal Consent Deed was made with a notarial deed. Although the APHT, which is the "base" of making mortgage certificates, is a PPAT deed, the consent deed remains the authority of a notary, not a PPAT. The registration process and completeness of the documents related to the Roya application using the Roya Consensus deed are the same as the general Roya service, as regulated in the Regulation of the Minister of Agrarian Spatial Planning/Head of BPN Number 3 of 1997 and Regulation of the Minister of Agrarian Spatial Planning/Head of BPN Number 1 of 2010. Deed roya permit made by a notary, its position is only as a substitute for a mortgage certificate lost in the roya process, not for execution, so that its position cannot be equated with a mortgage certificate which has executorial power because it is not regulated by law..

The research method used is descriptive method, while the data analysis technique uses qualitative. The results of the study indicate that the legal protection carried out against children as narcotics abusers in Indonesia based on Law No. 11 of 2012 concerning the Juvenile Criminal Justice System has been regulated starting from the process of investigation, arrest, detention, prosecution, examination in court and correctional. The Belawan Harbor Police Resort has made efforts to protect children who use narcotics by fulfilling children's rights during the investigation process, as well as seeking to resolve cases through diversion. Various obstacle factors faced by the protection of children who abuse narcotics are deviant behavior from child suspects, pressure on children from narcotics networks, the detention time of children is relatively short, there are restrictions on diversion requirements as non-repetition of criminal acts, and the cost of resolving cases through diversion is relatively large for costs. rehabilitation and consultation costs. It is recommended that the police not use children to uncover narcotics networks. The government needs to consider revising the SPPA Law by removing the diversion restriction as regulated in article 7 paragraph (2). The government needs to consider fully covering the costs of rehabilitating children who use narcotics at a more reasonable cost standard.
