Temperature Dependence and Potential of Nebulizer Spray Pyrolysis on Zinc Stannate (ZnSnO3) Thin Films for Ammonia Gas Sensors
This study focuses on the preparation and characterization of Zinc stannate (ZnSnO3) thin films using a nebulizer spray pyrolysis technique at different substrate temperatures ranging from 300 to 500 °C. The films were analyzed using X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis, ammonia gas sensitivity, electrical conductivity, and optical measurements. The XRD analysis revealed the presence of distinct crystallographic planes and improved crystallinity wi th increasing deposition temperature. SEM analysis showed a transition from amorphous to nanorod structures with increasing tempe...

Are deep learning classification results obtained on CT scans fair and interpretable?
AbstractFollowing the great success of various deep learning methods in image and object classification, the biomedical image processing society is also overwhelmed with their applications to various automatic diagnosis cases. Unfortunately, most of the deep learning-based classification attempts in the literature solely focus on the aim of extreme accuracy scores, without considering interpretability, or patient-wise separation of training and test data. For example, most lung nodule classification papers using deep learning randomly shuffle data and split it into training, validation, and test sets, causing certain image...

A low-cost phantom design for evaluating spine SABR calculations in the presence of prosthetic vertebral stabilization
We present an initial design for a low-cost phantom to evaluate spine stereotactic ablative radiotherapy (SABR) in the presence of prosthetic vertebral stabilization. The phantom is modular, allowing the prosthetic at the centre of the phantom to be removed by exchanging the central block. It also includes space to insert ion chamber and film. The agreement of the RayStation TPS (v8.0B) collapsed cone convolution (CCC) calculation and measurement was determined for phantom versions with and without prosthetic. There was little to no change in the agreement between the measured and calculated dose when introducing metallic ...

Automated cardiac arrhythmia detection techniques: a comprehensive review for prospective approach
In this study, it is noticed that the performance of the machine-learning-based arrhythmia detection techniques depend on pre-processing of ECG signal, R-peaks detection, features extraction and classification tools while the deep-learning-based techniques do not require the features extraction step. Generally, the existing techniques utilize Massachusetts Institute of Technology-Beth Israel Hospital arrhythmia database to evaluate the classification performance. The classification performance of automated techniques also depends on ECG data used for training and testing of the classifier. It is expected that the performan...

Bioprocess Biosyst Eng. 2024 Apr 3. doi: 10.1007/s00449-024-02973-x. Online ahead of print.ABSTRACTGluconic acid's potential as a wheat straw pretreatment agent was studied at different concentrations (0.125-1 M) and temperatures (160-190 °C) for 30 min, followed by enzymatic hydrolysis. 0.125 M gluconic acid, 170 °C, yielded the highest xylose output, while 0.5 M gluconic acid at 190 °C yielded the best glucose yield. A fraction of gluconic acid decomposed during pretreatment. Detoxified hemicellulose hydrolysate from 0.125 M gluconate at 170 °C for 60 min showed promise for ethanol production. The gluconate contained...

Synthesis of biopolymer blends nanocomposites embedded with mono-(Ag, Fe) and bi-(Ag-Fe) metallic nanoparticles using an eco-friendly approach for antimicrobial activities
We examined its efficacy against Escherichia coli, Staphylococcus aureus and Candida albicans as microorganisms. Good antibacterial and antifungal activity was observed. The bimetallic composites demonstrated greater activity than monometallic composites against these bacterial and fungal species. All bimetallic nanocomposites have shown enhanced, loss due to reflection, loss due to absorption, and the total EMI shielding efficiency at 8 GHz (X-band) and 16 GHz (Ku-band) frequency. All these results ratify, that these newly developed bio nanocomposites are most suitable in many applications, in EMI shielding, nanotechnolog...
