This article presents a cold-start linear branch flow model named modified DistFlow. In DistFlow, the active and reactive power are replaced by their ratios to voltage magnitude as state variables, so that errors introduced conventional linearization approaches due complete ignoring of network loss terms reduced. Based on path-branch incidence matrix, flows nodal magnitudes can be written in succinct matrix forms. Subsequently, proposed DistFlow is applied problem optimization...
Combined heat and electricity operation with variable mass flow rates promotes flexibility, economy, sustainability through synergies between electric power systems (EPSs) district heating (DHSs). Such combined presents a highly nonlinear nonconvex optimization problem, mainly due to the bilinear terms in model—that is, product of rate nodal temperature. Existing methods, such as optimization, generalized Benders decomposition, convex relaxation, still present challenges achieving...
Abstract Objectives The aim of this study was to determine the status tertiary lymphoid structures (TLSs) using radiomic features in patients with invasive pulmonary adenocarcinoma (IA). Methods In retrospective study, IA from November 2015 March 2024 were recruited two independent centers (center 1, training and internal test data set; center 2, external set). TLS divided into groups according hematoxylin-eosin staining. Radiomic extracted, support vector machine (SVM) implemented predict...
Endometrial cancer (EC) is a prevalent gynecologic malignancy where accurate grading and assessment are crucial for determining prognosis treatment strategies. Conventional MRI techniques, including apparent diffusion coefficient (ADC) T2-weighted imaging, often fail to capture the detailed microstructural complexities of EC. To evaluate efficacy relaxation correlated spectroscopic imaging (DR-CSI) in assessing EC compare its diagnostic performance with conventional ADC imaging. Sixty-two...
Summary In this paper, the exponential mean‐square stability of neutral switching Markovian jump systems with generally incomplete transition probabilities is investigated. The model discussed in paper concludes both deterministic signals and jumping signals. rates process are assumed to be partly available, that is, some elements have been exactly known, merely known lower upper bounds, others may no information use. Based on Lyapunov‐Krasovskii functional method, sufficient conditions...
Gliding arc is a mostly used non-equilibrium plasma generation method whose characteristic affected by the back-breakdown phenomenon. Mode transition induced of gliding studied in this work and effects gas flow rate, applied voltage, electrode parameters on mode were studied. Experimental results show that there are two typical modes during development arc. A comprises periodicitical from minimum gap breakdown to longest extinguishment, while B continues produce at ends electrodes. As rate...
Hydrotalcite intercalated nanohybrids have served as a vital phosphorescent photosensitizer owing to remarkable 1 O 2 quantum yield and high cell mortality performance.

Based model, three types equations, namely, power flow network and equations are presented allocate losses. By introducing path-branch incidence matrix, all can be in analytical forms for generalized radial distribution network. results IEEE 33-bus system show that: firstly, more accurate than DistFlow; secondly, decoupling losses by within an acceptable...
Abstract This paper describes the fracture of composite insulator string B phase on Tower 72 500kV line. A series tests have been taken core rod and sheath to analyze causation accident, including hydrophobicity test, dissection analysis, dye penetration, SEM FTIR. It is found that surface fault chalked, its reduced. The interface between epoxy resin matrix silicone rubber has completely failed. Epoxy degraded, partial discharge accelerates this process. main chain Si-O side Si-C in molecule...
저에너지(수 eV) 양전자 빔을 이용하여 도체나 반도체의 표면/계면의 물리화학적 특성 분석에 독특한 유용성이 보고 되고 있다. 기존의 표면 분석법에 비해 표면의 선택도가 향상되어 반도체 소자의 박막 두께가 얇아지는 최신기술에 적합한 분석법으로 주목을 받고 물질표면에 조사된 저에너지 양전자는 근처의 image potential에 포획이 되어 표면에 있는 전자들과 쌍소멸하며 Auger 전자를 방출한다. 표면으로부터 방출된 전자의 에너지를 측정함으로 원자의 화학적 구별이 가능하므로 검출기의 에너지 분해도가 중요하다. ExB 형태의 측정기는 <TEX>$6{\sim}10\;eV$</TEX> 정도이고 특정한 영역만을 일정시간 스캔하여 스펙트럼을 측정하므로 측정시간이 길어진다는 단점이 반면에 Time-Of-Flight(TOF) 시스템은 방출되는 전자들의 동시에 검출하므로 단축되어 측정 효율이 향상된다. 분해도를 높이기 위해서는 측정하고자 하는 진행거리를 길게 할수록 좋으나, 공간적 제약을...

In this paper, a novel quadratic convex optimal power flow model, namely, MDOPF, is proposed to determine the dispatches of distributed generators. Based on results two price mechanisms, distribution locational marginal (DLMP) and (DLP), are analyzed. For DLMP, an explicit method developed calculate loss that does not require backward/forward sweep algorithm thus reduces computational complexity. However, component in DLMP will cause over-collection losses (OCL). To address issue, DLP...
In this paper, we propose a convex planning model of integrated heat and electricity systems considering variable mass flow rates. The main challenge comes from the non-convexity bilinear terms in district heating network, i.e., product rate nodal temperature. To resolve issue, first reformulate network through equivalent transformation substitution. It shows that reformulated has only one set nonconvex constraints with reduced others are linear constraints. Such reformulation not guarantees...
