Conceptually, facility layout design (FLD) or facility layout planning (FLP) is an extensive terminology that encompasses the design of factories as well as hospitals, airports, retail stores, and other types of facilities [1]. Owing to the importance and complexity of production or manufacturing systems, the vast majority of research on FLD has focused on factory layout design or shop-floor design [2]. Therefore, the terms facility layout design, factory layout planning, and shop-floor layout are often used interchangeably. Macroscopically, FLD is inherently connected to the strategic planning of production and product development, as well as the planning of processes, machines, and equipment [3]. Facility layout design is crucial for optimizing production efficiency by strategically arranging resources, workstations, and equipment to streamline material flow, minimize transportation time, and reduce costs. FLD can be further divided into concept layout and detailed layout planning. A concept layout includes a coarse spatial representation of functional units with only limited consideration of detailed influences. These details are covered by the subsequent step of detailed layout planning. Generally, there are four basic types of layout, which are fixed-position layout, process layout, cellular layout, and product layout [4]. Each kind of layout has its own distinct advantages depending on the nature of the production process, types of product, and the production volume [5]. However, for a long time, no matter in theory or in practice, the problem of FLD was notoriously difficult for its complexity, and there is no ideal formulation method so far. Smith [6] argued that factory design problems inevitably face ten crucial dilemmas and corresponding deep-seated underlying paradoxes. In essence, the factory design process is essentially information-deficient and is an argumentative and dynamic process [7].This work outlines the evolution of facility layout design thro

Purpose Our study assessed the ability F-18-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) radiomics to differentiate breast carcinoma from breast lymphoma using machine-learning approach. Methods Sixty-five breast nodules from 44 patients diagnosed as breast carcinoma or breast lymphoma were included. Standardized uptake value (SUV) and radiomic features from CT and PET images were extracted using local image features extraction software. Six discriminative models including PETa (based on clinical, SUV and radiomic features from PET images), PETb (SUV and radiomic features from PET images), PETc (radiomic features only from PET images), CTa (clinical and radiomic features from CT images), CTb (radiomic features only from CT images), and SUV model were generated using least absolute shrinkage and selection operator method and linear discriminant analysis. The areas under the receiver operating characteristic curve (AUCs), accuracy, sensitivity, and specificity were calculated to evaluate the discriminative ability of these models. Results PETa and CTa models showed the best ability to differentiation in training and validation group (AUCs of 0.867 and 0.806 for PETa model, AUCs of 0.891 and 0.759 for CTa model, respectively). Conclusion Models based on clinical, SUV, and radiomic features of F-18-FDG PET/CT images could accurately discriminate breast carcinoma from breast lymphoma.

The high trap density (generally 10(16) to 10(18) cm(-3)) in thin films of organic semiconductors is the primary reason for the inferior charge-carrier mobility and large nonradiative recombination energy loss (Delta E-nr) in organic solar cells (OSCs), limiting improvement in power conversion efficiencies (PCEs). In this study, the trap density in OSCs is efficiently reduced via extending the donor core of nonfullerene acceptors (NFAs) from a heptacyclic unit to a nonacyclic unit. TTPIC-4F with a nonacyclic unit has stronger intramolecular and intermolecular interactions, affording higher crystallinity in thin films relative to its counterpart BTPIC-4F. Thus, the D18:TTPIC-4F-based device achieves a lower trap density of 4.02 x 10(15) cm(-3), comparable to some typical high-performance inorganic/hybrid semiconductors, with higher mobility and inhibited charge-carrier recombination in devices. Therefore, the D18:TTPIC-4F-based OSC exhibits an impressive PCE of 17.1% with a low Delta E-nr of 0.208 eV, which is the best known value for A-D-A-type NFAs. Therefore, extending the donor core of NFAs is an efficient method for suppressing trap states in OSCs for high PCEs.

Small metal clusters have received increasing attention due to their attractive and superior performance in electrocatalytic energy conversion. However, the design and synthesis of well-dispersed metal clusters is a great challenge owing to their ease of aggregation. Here, we develop a biomassin situconversion strategy to synthesize Fe single atomic sites (Fe-N-4) combined with ultra-small Fe(2)O(3)nanoclusters embedded in N, S codoped porous carbons (Fe-SA/FeONC/NSC) for the oxygen reduction reaction (ORR). The resultant Fe-SA/FeONC/NSC exhibits a high half-wave potential (E-1/2= 0.86 ***) and an outstanding kinetic current density at 0.80 V (J(k)= 32.15 mA cm(-2)), which even surpasses those of commercial Pt/C (E-1/2= 0.85 V,J(k)= 16.5 mA cm(-2)). Atomic level dispersed Fe-N(4)sites integrated with Fe(2)O(3)clusters embedded in N, S-mediated carbon are mainly responsible for the excellent ORR activity. More importantly, the assembled Zn-air battery can output a prominent power density of 179.0 mW cm(-2)and energy density of 837.4 W h kg(-1)along with robust stability, outperforming the commercial Pt/C and most non-platinum catalysts. This work opens up an avenue for biomassin situconversion into non-precious metal electrocatalysts for energy conversion and storage technologies.

BackgroundParagangliomas (PGLs) are extremely rare neuroendocrine tumours arising from extra-adrenal chromaffin cells. PGLs are clinically rare, difficult to diagnose and usually require surgical intervention. PGLs mostly present catecholamine-related symptoms. We report a case of Acute abdomen as the initial manifestation of haemorrhagic retroperitoneal PGL. There has been only one similar case reported in *** presentationWe present a unique case of a 52-year-old female with acute abdomen induced by haemorrhagic retroperitoneal PGL. The patient had a 5-h history of sudden onset of serve right lower quadrant abdominal pain radiating to the right flank and right lumbar region. Patient had classic symptoms of acute abdomen. Abdominal ultrasound revealed a large abdominal mass with a clear boundary. A Computed Tomography Angiography (CTA) of superior mesenteric artery was also performed to in the emergency department. The CTA demonstrated a large retroperitoneal mass measured 9.0x7.3 cm with higher density inside. A provisional diagnosis of retroperitoneal tumour with haemorrhage was made. The patient received intravenous fluids, broad-spectrum antibiotics and somatostatin. On the 3(rd) day of admission, her abdominal pain was slightly relieved, but haemoglobin decreased from 10.9 to 9.4 g/dL in 12 h suggesting that there might be active bleeding in the abdominal cavity. Thus, we performed a midline laparotomy for the patient. Haemorrhage was successfully stopped during operation. The retroperitoneal tumour with haemorrhage was completely removed. The abdominal pain was significantly relieved after surgery. The patient initially presented with acute abdomen instead of catecholamine-related symptoms. The diagnosis of retroperitoneal PGL with haemorrhage was finally confirmed by postoperative pathological and immunohistochemical results. The postoperative course was uneventful. At the 1-year follow-up visit, no tumour recurrence was observed by Single Photon

Shanghai Lingang New City, located in the southeast corner of Shanghai, was constructed by land reclamation from 2002 to 2005, in an area where the geological structure is prone to subsidence over time. Firstly, we explore the spatio-temporal pattern of ground subsidence and its mechanism using the Persistent Scatterers Interferometric Synthetic Aperture Radar (PSInSAR) technique by processing 50 scenes of Sentinel-1A images acquired from May 2016 to May 2018. In order to assess the accuracy of PSInSAR derived deformation, we collect the first-class leveling data at two benchmarks located in the study area;the comparison between the two settlement indicates that the maximum difference is 1.93 mm and 2.9 mm, respectively, which validates the PSInSAR's high accuracy. We then obtain the skeleton release coefficients by the joint analysis of PSInSAR measurements and groundwater level data. Finally, we find that this coastal area has undergone both elastic and inelastic deformation from 2016 to 2018. The outcome shows that the combination of different techniques is conductive to understand the deformation mechanism of the aquifer system in these coastal areas, which is expected to be a valuable reference for ground subsidence monitoring and groundwater extraction management.

BMC SURGERY 2022年第1期22卷 249-249页

Background Autoamputation of the appendix, i.e., complete separation of a part of the appendix without any surgical intervention, has been rarely documented in the literature in recent years. Herein, we report a case where the amputated part of the appendix was viable after autoamputation and reviewed the related literature. Case presentation A 39-year-old female patient was admitted to our hospital complaining of abdominal pain and subsequently underwent an emergency laparoscopic appendectomy (LA). Intraoperatively, we found an abnormally short appendix protruding from the cecum and a strip-like tissue attached to the mesoappendix, considered a duplex appendix, was resected. Finally, in conjunction with the histopathology findings and the past medical history, the patient was diagnosed with "Pseudo-duplication of the Appendix". Conclusions Autoamputation of the appendix resulting in preserved tissue viability and absence of necrosis at both ends, can be termed as "Pseudo-duplication of the Appendix". This condition is very rare in clinical practice and has not been reported in China, to the best of our knowledge. It has been established that the autoamputated appendix can produce chronic inflammation, intestinal fistulae and even cancer, affecting the patient's quality of life. Accordingly, a clear diagnosis and timely management are essential. In this report, we established a novel classification for "Pseudo-duplication of the Appendix", hoping that our report will help surgeons better understand this anatomical anomaly of the appendix, to help during the differential diagnosis process and avoid confusion.
