Published: July 2023

Using the renormalized wavefunction approach, we examined the excitonic quantum beat in a three-level system in disk-shaped quantum dots. The non-stationary electron wave function and the time-dependent exciton absorption intensity under the effect of an intensity pump laser that resonates with two excited electron states were also provided. Our numerical findings demonstrate that the time-dependent exciton absorption intensity takes the shape of a periodic oscillation when the quantum dot is subjected to a powerful resonant pump laser. This is clear evidence that quantum beats appears in the quantum disk. Additionally, the dot radius and the pump field detuning significantly affect the beat characteristics, such as frequency and amplitude.

Russell-Silver syndrome (RSS) is a rare genetic malformation characterized by the growth of a 2-year-old male child with RSS who underwent hip spica surgery under general anesthesia. The patient had a history of mild developmental delay, failure to gain weight, and frequent vomiting. Anesthetic implications of RSS, including airway management, glucose homeostasis, hypothermia, and pharmacological considerations, were considered during the patient's pre-operative assessment and intraoperative management. The patient was induced with propofol and fentanyl, and maintenance anesthesia was achieved with sevoflurane. The patient's airway was safely secured, and extubation was performed smoothly. The anesthetic management proceeded without complications, ensuring a successful outcome. This case report highlights the importance of considering the specific anesthetic implications of RSS in the perioperative management of patients with this rare genetic syndrome.

Published: July 2023

Brown-Sequard syndrome (BSS) is an uncommon condition caused by a localized injury to one side of the spinal cord. It is rarely reported to present because of cervical disc herniation (CDH), especially as a result of 2 consecutive discs prolapse, with only 8 cases reported worldwide, 4 of which have the cervical disc levels of C5-C6, C6-C7 being affected just like the case we are presenting. A 45 years male had complained of left-sided body pain and numbness following a fall, his symptoms progressing over two weeks to left side hemiparesis and impaired sensation; MRI of C spine revealed C5-C6, C6- C7 disc prolapse with cord compression resulting in BSS. The patient was treated surgically by anterior cervical discectomy and fusion (ACDF) followed by physiotherapy. The patient showed complete recovery in terms of sensory and motor deficits in both the right and left upper and lower limbs. We are stressing the role of detailed history, comprehensive neurological examination, and proper imaging in the early diagnosis of BSS. Treatment with anterior surgical intervention is the recommended approach in most reported cases and is associated with an excellent prognosis.

Authors: Muahiddah Nuri , Diamahesa Wastu Ayu
Published: July 2023

The use of immunostimulants from papaya leaves as a treatment strategy for fish diseases has gained attention in the field of aquaculture. Initial studies have shown that the active compounds in papaya leaves have the potential as immunostimulants to enhance the fish immune system and combat disease infections. Previous studies have revealed that the administration of papaya leaf extracts in fish feed can stimulate immune responses, including activating immune cells such as macrophages and increasing antibody production. The compounds in papaya leaves also exhibit antimicrobial effects that help fight against pathogens causing diseases in fish. Although research findings indicate the potential use of papaya leaf immunostimulants, further studies are needed to understand their mechanisms of action comprehensively. Factors such as effective dosage, optimal administration methods, and their effects on various diseases must be clarified. Safety aspects should also be considered, including potential side effects and residues in fish intended for human consumption. Consideration should also be given to sustainable fish farming practices and the potential environmental impacts of the widespread use of papaya leaf immunostimulants. In conclusion, using immunostimulants from papaya leaves to treat fish diseases shows promising potential. However, further research is required to understand their effects thoroughly, determine the appropriate dosage, evaluate the safety, and consider sustainable aquaculture aspects before their use can be widely recommended in aquaculture practices.

Craniospinal is known as the method to kill the cancer within a wide radiation area, starting from the cranial to spinal nervous system. In the case, the cancer has spread through the fluid of cerebro spinalis, such as medulloblastoma. We carried out the research to determine the isodose curve in medulloblastoma craniospinal patients and DVH (Dose Volume Histogram) statistic in the OAR (Organ at Risk) by using 3D-CRT radiotherapy technique.  To conduct the radiative treatment, we used the moving Junction method in which the radiation was divided into three Iso section, i.e.: Section Iso brain with gantry 90° and 270°, Section Iso thoracic with gantry 0°, and Section Iso lumbar with gantry 0°. Then, we analyzed the isodose curves and DVH statistics created by photon beams of 6 MV and 10 MV with and without considering the dose absorbed by OAR. We found that the isodose curves created with considering the OAR dose were better than those created without considering the OAR dose. We also found that the dose absorbed by OAR was within the tolerance limit stated in ICRU guidelines.

Introduction: Following the COVID-19 outbreak in China in December 2019, viral spread started to be seen in many countries. In March 2020, simultaneous with the pandemic declaration, the first case was observed in Northern Cyprus. During this time, the emergency department visit patterns showed differences worldwide.

Aim: Thus, this study aims to compare and contrast the differences between pre-pandemic and pandemic period emergency department visits resulting from any kind of drug and/or substance intoxication. To do so, a retrospective analysis was held using two private university hospitals’ electronic recording systems for the periods of 1st December 2017-9th March 2020 (before the pandemic) and 10th March 2020-30th June 2022 (during the COVID-19 pandemic).

Results: The demographic data were collected, and the study-specific data were grouped into 5 different intoxication categories. Data collected were compared in terms of pre- and post-pandemic timescales. The results showed that there is no significant difference between the demographic data of patients however, intoxication-related emergency department visits were significantly lower during the pandemic compared to the pre-pandemic period.

Conclusion: This study will be a pioneer in contributing to many social problems, especially substance abuse, which was previously lacking in scientific data in Northern Cyprus.

Наслідки військової агресії вимагають постійного моніторингу та контролю, аналізу ризиків, розробки та впровадження відповідних коригувальних дій та управлінських рішень, які є гнучкими та адаптуються до постійних та мінливих потреб. Щоб оцінити мінливі потреби, слід проводити постійну та безперервну оцінку потреб системи громадського здоров’я, орієнтуючись на конкретні надзвичайні запити громадського здоров’я. Всесвітньою організацією охорони здоров’я, Центрами з контролю та профілактики захворювань (CDC), EuroCDC, ОБСЄ, а також регіональними та місцевими організаціями розроблено ряд інструментів оцінки. Оцінювання використовує різноманітні підходи, включаючи зовнішнє та внутрішнє оцінювання, які спрямовані на розуміння конкретних потреб у відповідь на надзвичайні ситуації у сфері громадського здоров’я. З метою оцінювання потреб України в надзвичайних ситуаціях у сфері охорони здоров’я, ми провели огляд існуючих інструментів, які можуть бути використані для вирішення надзвичайних потреб у сфері охорони здоров’я в Україні через російську агресію. Було розглянуто окремі інструменти, включаючи інструменти для самооцінки та зовнішнього оцінювання. Висновки з огляду літератури представлені в статті аби поінформувати про стандарти готовності стстеми охорони громадського здоров’я до надзвичайних ситуацій, надати аналіз інструментів, які можуть бути корисними для інших процесів управління надзвичайними ситуаціями у сфері охорони громадського здоров’я та уникнути нестандартних оцінок.
Graphene oxide 2D thin films for electronic and photonic chips
Authors: Moss David
Published: July 2023

As a derivative of graphene, graphene oxide (GO) was initially developed by chemists to emulate some of the key properties of graphene, but it was soon recognized as a unique material in its own right, addressing an application space that is not accessible to chemical vapor deposition based materials. Over the past decade, GO has emerged as a new frontier material with tremendous advances in its material fabrication and quality control over its properties. These in turn have led to rapid progress in GO based photonics, electronics, and optoelectronics concepts and devices, evoking new science and paving the way for many technological breakthroughs with exceptional performance. Here, we review the unique fundamental characteristics of GO, its thin film fabrication methods, patterning techniques, and mechanisms for tuning its material properties. This latter capability in particular has enabled novel advanced functional photonic, electronic, and optoelectronic devices. Understanding these insights is essential for designing and tailoring GO properties for state-of-the-art applications including solar energy harvesting, energy storage, medical diagnosis, image displays, and optical communications. We conclude by discussing the open challenges and exciting opportunities of this field, together with future prospects for major technological advancements and breakthroughs.

Authors: Soomro Shuaib Ahmed , Ali Akhtiar , Nabi Agha Amad , Soomro Suhaib Ahmed
Published: July 2023

BACKGROUND: Due to the COVID-19 pandemic, many employees lost their jobs. At the same time, millions of individuals have been forced to relocate because of a “new normal, “ which requires them to work from home offices. Working from home poses difficulties for employees whose employers do not provide appropriate support to their home workplaces. Hence, it significantly affected employee performance and organizations. OBJECTIVE: This study utilizes stress theories to evaluate perceived job insecurity and perceived employability during COVID-19. The research examined perceived job insecurity and the resulting work stress, which led to adverse work outcomes. METHODS: The authors collected information from two multinational corporations and gathered longitudinal data in two waves. The authors used hierarchical regression for our data analysis. RESULTS: The findings indicated a substantial positive relationship between perceived job insecurity and work stress. Job insecurity in working environment has also increased, adversely affecting employee productivity. It follows from the moderated mediation analysis that perceived employability significantly impacts indirectly on work stress and outcomes. CONCLUSION: This study expands our knowledge and adds to the literature on workplace stress theories regarding COVID-19.
Universal optimality and robust utility bounds for metric differential privacy1
Authors: Fernandes Natasha , McIver Annabelle , Palamidessi Catuscia , Ding Ming
Published: July 2023

We study the privacy-utility trade-off in the context of metric differential privacy. Ghosh et al. introduced the idea of universal optimality to characterise the “best” mechanism for a certain query that simultaneously satisfies (a fixed) ε-differential privacy constraint whilst at the same time providing better utility compared to any other ε-differentially private mechanism for the same query. They showed that the Geometric mechanism is universally optimal for the class of counting queries. On the other hand, Brenner and Nissim showed that outside the space of counting queries, and for the Bayes risk loss function, no such universally optimal mechanisms exist. Except for the universal optimality of the Laplace mechanism, there have been no generalisations of these universally optimal results to other classes of differentially-private mechanisms. In this paper, we use metric differential privacy and quantitative information flow as the fundamental principle for studying universal optimality. Metric differential privacy is a generalisation of both standard (i.e., central) differential privacy and local differential privacy, and it is increasingly being used in various application domains, for instance in location privacy and in privacy-preserving machine learning. Similar to the approaches adopted by Ghosh et al. and Brenner and Nissim, we measure utility in terms of loss functions, and we interpret the notion of a privacy mechanism as an information-theoretic channel satisfying constraints defined by ε-differential privacy and a metric meaningful to the underlying state space. Using this framework we are able to clarify Nissim and Brenner’s negative results by (a) that in fact all privacy types contain optimal mechanisms relative to certain kinds of non-trivial loss functions, and (b) extending and generalising their negative results beyond Bayes risk specifically to a wide class of non-trivial loss functions. Our exploration suggests that universally optimal mechanisms are indeed rare within privacy types. We therefore propose weaker universal benchmarks of utility called privacy type capacities. We show that such capacities always exist and can be computed using a convex optimisation algorithm. Further, we illustrate these ideas on a selection of examples with several different underlying metrics.
Toward Predicting the Char Bed Shape in Kraft Recovery Boilers
Authors: ENGBLOM MARKUS , MUELLER CHRISTIAN , BRINK ANDERS , HUPA MIKKO , JONES ANDREW
Published: July 2023

The authors have developed a model for describing the time-dependent change in char bed shape in kraft recovery boilers, and have implemented this model into a computational fluid dynamics (CFD) environment. The model was tested by simulating a 3150 tons dry solids/day kraft recovery boiler, and was found to be capable of describing the change in bed shape resulting from calculated carbon accumulation. The model simulated the behavior of the actual char bed relatively well. The current model offers a structure for further development toward a char bed model with better shape-predicting capability.
