Penile epidermoid cysts are uncommon, and a small number of cases have been reported worldwide. We present the first documented patient with a penile epidermoid cyst which consisted of multiple focuses. A 37-year-old man presented to our department with a chief complaint of an asymptomatic, soft mass in the ventral part of the penis. the mass was nontender, freely movable and measuring 3 cm within the dermis. MRI (magnetic resonance imaging) revealed a high signal intensity on both t1- and t2-weighted images. Excision of the cyst was performed under local anesthesia. Macroscopically, the cut surface of the mass appeared to be full of a cheese-like material and the cyst consisted of multiple focuses. the cyst did not contain skin appendages. the pathological diagnosis was an epidermoid cyst of the penis. No recurrence has been noted in the year since the operation.

Accurately simulating the geographical distribution and temporal variability of global surface ozone has long been one of the principal components of chemistry-climate ***,the simulation outcomes have been reported to vary significantly as a result of the complex mixture of uncertain factors that control the tropospheric ozone *** the cross-model discrepancies to achieve higher accuracy predictions of surface ozone is thus a task of priority,and methods that overcome structural biases in models going beyond naïve averaging of model simulations are urgently *** on the Coupled Model Intercomparison Project Phase 6(CMIP6),we have transplanted a conventional ensemble learning approach,and also constructed an innovative 2-stage enhanced space-time Bayesian neural network to fuse an ensemble of 57 simulations together with a prescribed ozone dataset,both of which have realised outstanding performances(R2>0.95,RMSEthe conventional ensemble learning approach is computationally cheaper and results in higher overall performance,but at the expense of oceanic ozone being overestimated and the learning process being *** Bayesian approach performs better in spatial generalisation and enables perceivable interpretability,but induces heavier computational *** of these multi-stage machine learning-based approaches provide frameworks for improving the fidelity of composition-climate model outputs for uses in future impact studies.

Polymer gels are three-dimensional dosimetric tools. the purpose of the present study was to investigate the temperature dependence of polymer gels during scanning Magnetic Resonance Imaging. Prepared gels were irradiated with a 6MV X-ray beam at intensities ranging from 0 to 20 Gy in order to investigate their dose-R2 and dose-R1 responses. Irradiated gels were evaluated from 1.5-t magnetic resonance R2 and R1 images for each 5°C change in temperature from 5°C to 41°C, and then the four-field box technique irradiation plan was used to deliver a total dose of 4 Gy using the same beam weight in each direction to the prepared gels. the profile of the dose map generated from the four-field irradiated gel data at 20°C was then compared with the planned data. the dose-R2 response curve was linear up to 20 Gy at 20°C, with a slope of 1.17 Gy-1˙s-1. the slopes of the fitted curves of the dose-R2 decreased as gel temperature increased. the slopes of the dose-R1 curves were more parallel than the slopes of the dose-R2 curves between 5 and 41°C. the difference in the full width of half maximum of the gel profile data obtained using the four-field box technique at 20°C and the planned data were below 5% on average. the dose map from the irradiated gels obtained using the dose-R2 curve was the same as that from the planned data under the same temperature conditions. Measurement of difference between various temperatures is significant with dose accuracy. It is suitable to evaluate the gel dosimeter under the thermal equilibrium condition, MRI room temperature from the point of view of the stability of the irradiated gels.

Just like in animals, the essence of fertilization process in plants is the fusion of male andfemale gametes. Although it is already possible, with the aid of cytological manipulation, toachieve in vitro fusion of isolated egg and sperm cell to form zygote, it remains to be solvedwhether the fusion of male and female gametes in nature is at random or there exists some kindof 'recognition'.

Macroautophagy （here autophagy） is a catabolic mechanism responsible for the degradation of bulk cytoplasm, long-lived proteins and organeUes. During autophagy, the cargos are engulfed by double-membrane structures named phagophores, which expand to form the autophagosomes. Subsequently, these autophagosomes fuse with lysosomes, in which the cytoplasmic cargos are degraded. Autophagy is a constitutive pro- cess, which plays an important role in cellular homeostasis. In primary neurons autophagosome formation occurs continuously and preferentially at the distal end of axons. On the other hand, autophagy is increased by different stresses, and its dysregulation or excessive induction may lead to detrimental effects. Many neurological disorders have been associated with alterations in the autophagic pathway and an increase in autophagy during axonal degeneration was described.

在新自由主义的推波助澜下,公共管理主义被视为诊治公部门效能不彰的万灵丹,因为其效能要求契合集体利益之社会期望,因而取得市民社会的支持,继而转变为强力的社会论述,以驱动政府进行高等教育革新。然而,批评者却认为,此种表现力思维强化大学的科层性,并削弱教师的专业自主权,其商业逻辑使大学文化转向功利主义。本文指出,这些批评陷落于结构主义的预设立场,致使未能深究为何公共管理主义能如此兴盛。绩效主义开启学术取向的结构脉络,此种脉络的制度化酬赏原则强化个人化的成就动机,进而汇流成集体化的学术主义,因而削弱科层体制中私心与权威结合的保守文化,继而提升组织效能。此种新学术主义彰显出,公共管理主义的效能法则赢得大学内部的支持,因而强化其社会论述的影响力。

Fault Ride-through （FRt） capabilities set up according to the grid codes may affect the performance of related protective elements during fault periods. therefore, in this paper the coordination between the FRt capability and over-current protection of DFIG Wind Generators in MV networks is investigated. Simulation test cases using MAtLAB-Simulink are implemented on a 365-MW wind farm in AL-Zaafarana, Egypt. the simulation results show the influence of the FRt capability on the protective relaying coordination in wind farms, showing that the FRt may work in situations where is were expected not to work, and then disabling the over-current protection, which should have worked in this situation.
