In today's world, with rapid advancement of technology and the need for a shift towards green energy, it is seen that the power grid especially on the low voltage (LV) side is becoming more complex than ever. Introduction of different appliances has made it harder to comprehend the grid accurately. For this very reason, Gaussian mixture modelling is turned to for modelling of LV load models which is described in this paper. The advantages of this method along with validation for a set of LV networks against the secondary substation measurements is done. Further steps to be taken in order to improve upon this load model are explained in conclusions.

<div>AbstractPurpose:<p>Report results of the phase Ib dose-escalation/expansion study of triplet therapy with cyclin-dependent kinases 4 and 6 (CDK4/6) inhibitor (ribociclib), mTOR inhibitor (everolimus), and endocrine therapy (exemestane).</p>Patients and Methods:<p>Postmenopausal women with hormone receptor-positive (HR<sup>+</sup>), human epidermal growth factor receptor 2-negative (HER2<sup>−</sup>), pretreated, advanced breast cancer (ABC) were enrolled. The primary objective of the dose-escalation phase was to estimate the MTD and recommended phase II dose (RP2D) of triplet therapy through evaluation of the incidence of dose-limiting toxicities. Safety, tolerability, and efficacy of the RP2D were evaluated in the dose-expansion phase in patients naïve or refractory to CDK4/6 inhibitor therapy.</p>Results:<p>Patients (<i>N</i> = 116) received triplet therapy (<i>n</i> = 83 in the dose-escalation phase; <i>n</i> = 33 in the dose-expansion phase). A dose-dependent drug–drug interaction was observed for everolimus, with exposure increasing two- to fourfold in the presence of ribociclib. The RP2D was determined to be ribociclib 300 mg once daily, 3 weeks on/1 week off in a 4-week cycle, plus everolimus 2.5 mg once daily, plus exemestane 25 mg once daily taken with food. The safety profile was consistent with the known profiles of the combination partners, and preliminary evidence of antitumor activity was observed. Higher <i>ESR1</i> gene expression trended with better treatment response to triplet therapy; higher gene expression of MAPK pathway genes trended with worse treatment response.</p>Conclusions:<p>Triplet therapy with endocrine therapy and mTOR and CDK4/6 inhibition provides clinical benefit and an acceptable safety profile in previously treated postmenopausal women with HR<sup>+</sup>, HER2<sup>−</sup> ABC.</p></div>

Adaptive optics, in combination with multi-photon techniques, is a powerful approach to image deep into a specimen. Remarkably, virtually all adaptive optics schemes today rely on wavefront modulators that are reflective, diffractive or both. This, however, can pose a severe limitation for applications. Here, we present a fast and robust sensorless adaptive optics scheme adapted for transmissive wavefront modulators. We study our scheme in numerical simulations and in experiments with a novel, optofluidic wavefront shaping device that is transmissive, refractive, polarisation-independent, and broadband. We demonstrate scatter correction of two-photon-excited fluorescence images of microbeads as well as brain cells and benchmark our device against a liquid-crystal spatial light modulator. Our method and technology could open new routes for adaptive optics in scenarios where previously, the restriction to reflective and diffractive devices may have staggered innovation and progress.

Italy was among the first countries hit by the pandemic of coronavirus disease 2019 (COVID-19). The application of strict lockdown measures disproportionately affected both cancer patient care as well as cancer research. A survey was conducted among Italian oncologists to explore whether and how the COVID-19 outbreak has changed their aptitudes and practice toward … Continued

Melanoma is the deadliest form of skin cancer and has the ability to metastasize widely. Accurate diagnosis of sentinel lymph nodes (SLN) is crucial to its management. The gold standard for SLN identification is planar lymphoscintigraphy. Recently, single-photon emission computed tomography combined with computed tomography (SPECT/CT) has been used as a hybrid method to map lymphatic drainage networks. We aim to better characterize the utility of this tool in head and neck melanoma by evaluating its effectiveness in the preoperative setting for melanoma patients undergoing sentinel lymph node biopsy (SLNB). We performed a retrospective chart review at the West Haven Veterans Affairs Hospital. Inclusion criteria were patients with melanoma with a thickness greater than 0.75 mm and SPECT/CT use before operative sentinel lymph node excision. Exclusion criteria included clinically palpable lymph nodes, evidence of distant metastatic disease, melanoma with a Breslow depth less than 0.75 mm, and melanoma in situ. Our primary endpoints were correlation with intraoperative findings and whether the test had any influence on the operative plan. Thirty-five patients between 2011 and 2017 met our criteria. SPECT/CT correlated with the sentinel node biopsy based on intraoperative lymphoscintigraphy in 30 (86%) of 35 cases, and there were no changes to the operative plan after SPECT/CT was performed. Sentinel lymph nodes were correctly identified in all 35 cases. The role of SPECT/CT in SLNB is uncertain. According to some studies, SPECT/CT can help decision making and change surgical approach in up to 35% of patients. However, other studies have reported questionable correlation with intraoperative findings and no added intraoperative value in over 50% of patients. We have demonstrated that preoperative SPECT/CT was consistent with intraoperative findings in 86.0% of cases but did not change the surgical approach for the SLNB. Surveillance over a period of 12 months did not reveal any signs of melanoma recurrence. A possible advantage of SPECT/CT is potentially decreasing costs by lowering operative time. However, financial cost in the literature suggests SPECT/CT is costlier than lymphoscintigraphy and therefore this must be weighed against any potential benefit. Overall, we did not find that SPECT/CT gives added value when compared with lymphoscintigraphy.
