Abstract Chronic obstructive pulmonary disease (COPD) and sleep apnoea (OSA) syndrome (OSAS) are both common conditions. Their comorbid association – overlap (OVS) can result in clinically important nocturnal oxygen desaturation. We sought to compare demographic anthropometric characteristics, associated comorbidities saturation patients with OVS versus OSA alone. Methods included consecutive d...
Oncolytic viruses (OVs) are capable of exerting anti-cancer effects by a variety of mechanisms, including immune-mediated tumor cell death, highlighting their potential use in immunotherapy. Several adaptation mechanisms such as autophagy contribute to OV-mediated anti-tumor properties. Autophagy regulates immunogenic signaling during cancer therapy which can be utilized to design therapeutic c...
Multiply charged optical vortex solitons (OVS) (m=1,...,4) are generated in a thermal nonlinear medium with saturation. The respective soliton constants are found to be linearly proportional to the topological charges. Special attention is paid to the modulational instability, which is effectively suppressed by a moderate saturation but still remains an increasing function of the topological ch...
در این مقاله یک مبدل دو طرفه جدید ایزوله ارائه شده است. این مبدل از دو ترانسفورمر فوروارد و فلای بک تشکیل گردیده و تنها یک سوییچ در طرف اولیه و یک سوییچ در طرف ثانویه ترانسفورمر دارد. این مبدل به صورت PWM کنترل میگردد و از آنجایی که در هر دو حالت خاموش و روشن بودن سوییچها توان به خروجی منتقل میگردد، چگالی توان آن نسبت به مبدلهای قبلی بالاتر است. از طرفی مبدل مذکور قادر است که از هر دو طرف به ...
Occupants can provide valuable feedback on the indoor environmental quality of buildings. Research occupant voting systems (OVS) has demonstrated that apps or electronic devices act as viable tools for collecting long-term from occupants. However, previous research only to a limited extent explored occupants’ interaction with OVS and impact it might have reliability collected feedback. The pres...
Smartphone applications or electronic devices in the form of occupant voting systems (OVS) have demonstrated to be feasible for acquiring feedback from occupants support building operation manager identify indoor environmental quality (IEQ) problems and inappropriate control settings heating, ventilation air-conditioning (HVAC). The present paper aims contribute growing research on OVS as a too...
adenocarcinoma (PDAC) remains a highly lethal disease with a median survival time that does not exceed 6.5 months [1]. Since more than 80% of patients present with advanced metastatic disease, systemic chemotherapy remains the only treatment. The high resistance to conventional and targeted therapies in PDAC as in other desmoplastic tumors of adults is largely due to the dense extracellular mat...
The controlled introduction of oxygen vacancies (OVs) in photocatalysts has been demonstrated to be an efficient approach for improving the separation photogenerated charge carriers, and thus, enhancing photocatalytic performance photocatalysts. In this study, a two-step calcination method where ZIF-8 was used as precursor explored synthesis ZIF-8-derived ZnO nanoparticles with gradient distrib...
Piezo-photocatalysis has emerged as a promising strategy to address environmental pollution and the fast-growing energy shortage. Unfortunately, current efficiencies of piezo-photocatalysts are still far from ideal, improving their catalytic efficiency remains challenging. In this paper, we introduce oxygen vacancies (OVs) in Bi4Ti3O12 (BIT) nanosheets boost piezo-photocatalytic performance. Co...
