Minichromosome maintenance complex component 7 (MCM7) belongs to the minichromosome family that is important for initiation of eukaryotic DNA replication. Overexpression MCM7 protein relative cellular proliferation and responsible aggressive malignancy in various cancers. Mechanistically, inhibition significantly reduces associated with cancer. To date, no effective small molecular candidate has been identified can block progression cancer induced by protein. Therefore, study designed...

Electrifying medium- and heavy-duty trucks is critical to decarbonizing the transportation sector. The energy needs of electric will likely require megawatt-scale charging stations, which could significantly stress distribution grid. Distributed resources (DERs) can alleviate this reduce costs with proper management. To that end, work develops a hierarchical predictive control algorithm for future multiport stations provide real-time management decide rates, dispatch storage system (ESS),...

Without a reliable metering and communication infrastructure, the smart grid could become catastrophe to national security economy. A true infrastructure should detect all existing predict future threats through intrusion detection methods. Smart grids are susceptible various physical cyber-attack as result of communication, control computation vulnerabilities employed in grid. The paper provides comprehensive study on types solutions infrastructures. As part this survey, infrastructures...

The short-circuit response of inverter-interfaced distributed generators (IIDGs) is not adequately represented in many conventional protection studies. This paper presents an in-depth analysis IIDG behavior during grid faults and proposes a more accurate reduced-order parameterized current (RPSC) model inverters. Typical inverter components are thoroughly investigated to identify those that play dominant roles faults. shows the limiter factor for steady-state fault-current inverter; while...

This paper investigates the test procedures specified in UL 1741 SA and upcoming revision to IEEE P1547.1. A 550 kVA photovoltaic inverter was chosen for tests. research reveals some of key components consider while doing certification tests also identifies issues requiring consideration future releases standard, i.e.

Inverter-based DER responses to faults on the electric power system are different than those of conventional generators and often poorly understood. Inverter fault largely software-defined, within physics-based constraints. DERs regulated by standards grid codes that also constrain their responses. Though response will vary widely, for any following particular standard, a pattern can be synthesized observing standard. In this paper, recently published IEEE 1547-2018 is examined explore...

This paper proposes a distributed control method based on consensus algorithm for energy resources (DERs) using blockchain as secure communication medium cyber resilience. Each DER communicates with local server that is maintained by the ledger technology to allow securely sharing measurements among neighbouring assets achieve global objectives, i.e., voltage and frequency regulation well accurate power DERs, including collective grid-forming capability. To prove can retain system stability...

This paper presents an analysis of grid voltage control strategies for heavy-duty electric vehicle charging stations. The performance three approaches-including power factor control, standardized volt-volt ampere reactive (VAR) curve and customized volt-VAR control-are investigated evaluated different sizes stations, including a single-port station, midsized three-port six-port travel center. stations are placed on multiple locations four types distribution systems to obtain comprehensive...

In this paper, a state-of-charge (SoC) based distributed cooperative control (DCC) strategy has been proposed for minimizing the voltage regulation and proportional power sharing (in per unit) among Plug-in-Electric Vehicles (PEVs) generations (DGs) connected in DC μGrid. The method can charging discharging rates of PEVs depending on available generation capacity Using information from neighboring DGs only, global μGrid is estimated load converters achieved by methodology.

This paper investigates induced oscillation (specifically subsynchronous torsional interactions) in power systems arising from photovoltaic (PV) modulation. Time domain simulations of a modified IEEE first-benchmark system are presented and analyzed. In the benchmark system, PV generator was added at same bus where synchronous is connected. The impact different parameters inverters' volt-volt-ampere reactive (volt-var) curve on SSTI examined. most severe found arises time response inverter's...

The hybrid micro-grid is developing because of providing reliable electricity from renewable energy sources. This paper introduces AC/DC micro-grids which will help to develop distribution generation system and the interconnection between customer.

Different coordination control systems are proposed for assuring stability under...

Momentary cessation (MC) and response to rate-of-change-of-frequency (ROCOF) are inverter responses that can have serious impact on the stability of grid during abnormal conditions. Though IEEE Std 1547-2018 provides fairly well defined expected from inverter-based DERs conditions, a significant portion currently installed in distribution network do not Any analysis involving MC ROCOF must consider specific characteristics these for better confidence results, especially grids with high...

Background: Whipple surgery, or pancreaticoduodenectomy, is a complex surgical procedure often performed to treat pancreatic and periampullary cancers. Quality of life (QOL) performance status are critical metrics for assessing post-operative outcomes. This study aimed evaluate the QOL patients after surgery in tertiary care centre Bangladesh. Methods: cross-sectional was conducted among 64 who underwent at Sheikh Russel National Gastroliver Institute Hospital, Dhaka, Bangladesh between...

Background: Complications of pancreatic stump reconstruction after pancreaticoduodenectomy (PD) can lead to severe morbidity or even mortality. This study is taken see the postoperative outcome pancreatico-gastrostomy (PG) over pancreaticojejunostomy (PJ) PD. Aim was compare outcomes PG and PJ following PD in a cross-sectional analysis.
