Cybersecurity is an organizational issue that should be looked at through the lens of various stakeholders. However, it is often treated as a siloed issue in which more is always seen as better. The CISOs, CIOs, and the key decision-makers struggle to understand how much security is enough. Cybersecurity solutions, referred to as controls, more often than not result in a residual risk. To assess this risk better, the security controls should be studied in further detail. The objective of this paper is to educate the audience with the various cyber security controls being used in the academia and in the industry. In order to circumvent the security issues faced by large organization, the tradeoffs of each controls should be studied further. The paper is meant to provide a balanced view providing the positive and the critical aspect of implementing some of the known security solutions. There is no one perfect formula when it comes to selecting security controls. However, picking a security control that are in line with the users’ needs will help reduce some of the risks associated with implementing the controls. An optimal solution requires a balanced approach towards the risk, cost, and benefit of the solution. The aim of the paper is to help the reader assess some of risks and the tradeoff associated with the security controls being practiced in the industry today.

Biomedical waste has the potential to be hazardous and cause environmental pollution, therefore its proper management and disposal, especially in hospitals and healthcare facilities, plays an important role in protecting both the environment and public health. Biomedical waste encompasses a diverse array of materials originating from patient care, research activities, and medical interventions, and inadequate handling poses significant hazards. Common disposal methods, such as incineration, have been associated with environmental contamination and the emission of harmful fumes. Biomedical waste poses health risks through the spread of infectious diseases, particularly via sharps injuries, and the release of toxic compounds into the environment. The hazardous category includes infectious, potentially hazardous, and radioactive waste, with around 10% of hospital waste deemed infectious according to the World Health Organization. Various disposal techniques, including burning, autoclaving, microwaving, shredding, landfilling, and chemical treatments, are employed globally, each with its own benefits and limitations. In this review, a classification of the various categories of biomedical waste and its effects, treatment and disposal methods are discussed. In summary, the substantial impact of biomedical waste on the environment and public health necessitates careful handling and adherence to regulations. The implementation of sustainable waste management practices, promotion of recycling, and adoption of innovative technologies are essential for mitigating the adverse effects of biomedical waste on the environment and local communities.

Superconducting quantum interference device (SQUID) which is made of two parallel Josephson junctions has applications in magnetometry. A similar spin-based device is proposed here where spin superfluid in ferromagnet (FM) mimics the superconducting state. Two materials CoFeB and Fe3Sn are used for spin superfluid-based SQUID like device where easy plane anisotropy in CoFeB can be engineered and Fe3Sn has inherent easy plane anisotropy. Frequency varies in spin based proposed devices. Frequency increases and again decreases with the increase in both applied magnetic field and applied spin current. The proposed device can be used as nano oscillator and detector. The frequency in the proposed device shows multiple frequency steps which can be used for neuromorphic applications.

Authentication of TPS is the component of the QA program for RTPS and planning process. So, verification of dose calculation algorithm is essential to measure the efficiency of the dose calculations. The goal is to assess how far the dosage measured deviates from the dose predicted by the treatment planning system (TPS) algorithm using a CIRS Thorax phantom. It has been done to measure the dosimetric variations of 6MV, 10MV and 15MV photon beams. The phantom was initially scanned using a CT-simulator, and the raw data from the gated scans were then exported to TPS to perform the planning. Using this planning, the phantom was irradiated for four different cases. The computed dose was then compared with the measured dose to ensure TPS validity. The findings demonstrate that the variation between the measured doses in altered holes of the CIRS thorax phantom and the calculated doses by TPS was within the allowed limit except few points of four cases. Max. and Min. deviations for 6MV were 3.87% and 0.05% respectively. On the other hand, Max. and Min. deviations for 10MV were 7.87% and 0.12% respectively and that for 15MV are 4.44% and 0.02% respectively. Satisfactory results were obtained for lung and bone substitute. The results demonstrate the accuracy of the doses determined by the treatment planning system algorithm using a thorax phantom, and they also demonstrate the competency of using the phantom for regular verification. In case of external beam radiation therapy with AAA algorithm, the CIRS Thorax Phantom is suitable for dose computation in heterogeneous medium. However it is more compatible for 6MV than 10MV and 15MV.

The manufacturing of sputtering targets diverges from the conventional methods in ceramic processing, primarily because the quantities produced are frequently limited. The application of hot-press in this scenario significantly simplifies the sputter target fabrication process, allowing precise control over both target density and dimensions during pressing. However, without a hot press, the fabrication necessitates substantial preliminary efforts, which may be challenging to justify due to the restricted production volume. This study utilizes polytetrafluoroethylene (PTFE) rings as compaction dies filled with powders. Subsequently, the die is deformed between parallel platens, effectively compacting the powders. The method relies on the characteristic that the pressing results in minimal change in the internal diameter of the ring. This approach was exemplified through the creation of 2-inch (La0.5Sr0.5) MnO3-δ (LSM) and (La0.8Sr0.2) FeO3-δ (LSF) targets, where the deformable die was sized based on preliminary experiments involving smaller-diameter PTFE rings. The outcome of this fabrication process successfully produced sputter targets with high density, well within the tolerances of the sputter gun. Further tests involved using the prepared targets for the successful deposition of thin film LSM-LSF composite cathodes for SOFC applications.

Smart grids have emerged as a transformative technology in the energy sector, enabling efficient electricity management, improved reliability, and integration of renewable energy sources. The necessity to promote smart grid (SG) has been recognized with a strong consensus. The SG integrates electrical grids and communication infrastructures and forms an intelligent electricity network working with all connected components to deliver sustainable electricity supplies. Many advanced communication technologies have been identified for SG applications with a potential to significantly enhance the overall efficiency of power grids. However, the widespread deployment of smart grids raises concerns about the privacy and security of the data collected and transmitted by these systems. To address these concerns, this paper proposes a comprehensive framework for ensuring privacy and security in smart grid systems. This framework includes encryption techniques, access control mechanisms, and robust authentication protocols. Additionally, this paper discusses the importance of user awareness and education in mitigating privacy and security risks. The research contributes to the existing literature on smart grid privacy and security by providing insights specific to the information technology security domain. The findings of this manuscript will be valuable for policymakers, energy providers, and researchers working towards the development of secure and privacy-preserving smart grid systems.
