世界城市地区的人口不断增加,按此趋势发展,到2025年世界城市人口将达到43亿。与此同时,城市生活垃圾也逐渐增加,到2025年,将从现在的13亿吨增加到22亿吨。在这些垃圾中,玻璃占5%,而且只有不到30%可循环利用,这意味着4 600万吨是填埋处理的。到2025年大约7 700万吨废弃玻璃需要进行填埋处理。尽管玻璃可以回收利用,但由于各方面原因使得玻璃的回收利用非常复杂,其中之一是因为需对玻璃进行颜色分类处理。目前,废玻璃已经用于替代部分硅酸盐水泥和骨料,但存在碱骨料反应的风险。废玻璃作为化学激发胶凝材料具有很大的潜力。但是关于该方面的研究很少,主要问题是将废玻璃作为碱激发胶凝材料使用时,其部分水化产物易溶于水。使用碱性激发剂激活其他含钙胶凝材料,如碳酸盐、矿粉等复合胶凝材料是可行的,且可得到性能优异的净浆和混凝土。讨论不同废玻璃水化反应产物的组成和结构,分析将废玻璃作为胶凝材料再利用在玻璃循环利用方面的可行性和优势。

We show that highly doped graphene ribbons can support surface plasmons at near-infrared frequencies when their width is in the nanometer range,leading to important nonlocal and finite quantum-size corrections,such as sizable blueshifts.The magnitude of these effects is assessed by comparing classical and quantum-mechanical models to describe graphene plasmons.More precisely,we examine individual and interacting 6–8 nm wide zigzag and armchair ribbons doped to 0.4–1.5 eV Fermi energies.We find a strong influence of nonlocal effects on the orientation of graphene edges,with plasmons in zigzag ribbons undergoing strong quenching when their energy is below the Fermi level.Nonlocality is also affecting the hybridization between ribbon plasmons in dimers and arrays for separations below a few nanometers.Remarkably,the removal of a single row of atomic bonds in a ribbon produces a strong plasmon frequency shift,whereas the removal of bonds along an array of rows separated by several nanometers in an extended sheet causes a dramatic increase in the absorption.Besides the fundamental interest of these results,our work supports the use of narrow ribbons to achieve electro-optical modulation in the near infrared.

Current LTE networks are experiencing significant growth in the number of users worldwide. The use of data services for online browsing, e-learning, online meetings and initiatives such as smart cities means that subscribers stay connected for long periods, thereby saturating a number of signalling resources. One of such resources is the Radio Resource Connected (RRC) parameter, which is allocated to eNodeBs with the aim of limiting the number of connected simultaneously in the network. The fixed allocation of this parameter means that, depending on the traffic at different times of the day and the geographical position, some eNodeBs are saturated with RRC resources (overused) while others have unused RRC resources. However, as these resources are limited, there is the problem of their underutilization (non-optimal utilization of resources at the eNodeB level) due to static allocation (manual configuration of resources). The objective of this paper is to design an efficient machine learning model that will take as input some key performance indices (KPIs) like traffic data, RRC, simultaneous users, etc., for each eNodeB per hour and per day and accurately predict the number of needed RRC resources that will be dynamically allocated to them in order to avoid traffic and financial losses to the mobile network operator. To reach this target, three machine learning algorithms have been studied namely: linear regression, convolutional neural networks and long short-term memory (LSTM) to train three models and evaluate them. The model trained with the LSTM algorithm gave the best performance with 97% accuracy and was therefore implemented in the proposed solution for RRC resource allocation. An interconnection architecture is also proposed to embed the proposed solution into the Operation and maintenance network of a mobile network operator. In this way, the proposed solution can contribute to developing and expanding the concept of Self Organizing Network (SON) used in 4G and 5G networks.

Cyclin-dependent kinases 4 and 6(CDK4/6)inhibitors demonstrated activity in terms of progression-free survival(PFS)in advanced dedifferentiated liposarcoma(DD-LPS),a sarcoma with CDK4 amplification.CDK4 overexpression is by far more common than amplification in sarcomas and it might be a rational target for CDK inhibitors.Preclinical investigators of this study found that CDK4 overexpression,while not of CDKN2A,was the most consistent predictive factor for palbociclib efficacy in sarcomas.Advanced adult-type soft-tissue sarcoma,excluding DD-LPS,or bone sarcoma patients,progressing after at least one systemic line,whose tumors overexpressed CDK4,but not CDKN2A at baseline biopsy,were accrued in this single-arm phase II trial(EudraCT number:2016-004039-19).With the main endpoint of a 6-month PFS rate,40%was considered promising in this population.Palbociclib was administered orally at 125 mg/day for 21 days in 28-day cycles.A total of 214 patients with 236 CDK4/CDKN2A determinations were assessed for prescreening,archival material(141),and screening,baseline biopsy(95).There were 28(29%)with favorable mRNA profiles from 95 screened patients at baseline.From 23 enrolled patients,21 evaluable,the 6-month PFS rate was 29%(95%CI 9–48),and there were 6 patients out of 21 with a PFS longer than 6 months.The median PFS and overall survival were 4.2(95%CI 3.6–4.8)and 12(95%CI 8.7–15.4)months,respectively.Translational research showed a significant correlation between CDK4 mRNA and protein expression.Palbociclib was active in a variety of sarcoma subtypes,selected by CDK4/CDKN2A,and deserves further investigation in the sarcoma context.

BACKGROUND Metastatic small bowel low-grade neuroendocrine tumors(NETs)have a good prognosis.Surgery is the only curative treatment;however,this may induce advanced liver disease,particularly in long-term survivor patients.Acquired hepatocerebral degeneration or Parkinsonism in cirrhosis is characterized by rapidly progressive extrapyramidal symptoms in patients with advanced liver disease.CASE SUMMARY A 70-year-old man presented to the emergency department with diminished consciousness and disorientation,and was diagnosed with hepatic encephalopathy.The patient was diagnosed in 1993 with a metastatic small bowel NET,for which he twice underwent hepatic surgery,with metastatic resection in 1993 and a right hepatectomy in 2002 to remove two hepatic metastases.In 2003,the patient started first-line chemotherapy and in 2004 started the first of three consecutive biological treatments,followed by radio-molecular therapy,achieving stable disease for 14 years.Disease progression was identified and he underwent an endoscopic retrograde cholangiopancreatography.However,in 2019 advanced liver disease was identified.We diagnosed the development of acquired hepatocerebral degeneration,an unusual long-term side effect after multiple hepatic procedures.CONCLUSION The importance of regular and ongoing surveillance in long-term NET survivors who undergo hepatic procedures should be integrated into the therapeutic management plan,as some of these negative outcomes could be prevented.

The aim of this study was to evaluate the genotoxicity induced by cyclophosphamide-adriamycin treatment in breast cancer patients through the frequencies of Sister Chromatid Exchange (SCE), Replication Index (RI), Mitotic Index (MI) and Cell Proliferation Index (CPI) and to study the possible association between biomarkers of genotoxicity and the early response to treatment. The frequencies were obtained before and immediately after therapy from 17 patients with breast cancer (p < 0.001). Response to treatment was assessed after two years resulting in 12 patients in a state of remission. MI and CPI had high values after treatment in women with active cancers compared to those in a state of remission, however there were not significant differences. Conclusions: It is possible that MI y CPI biomarkers can serve as indicators for early assessment of treatment with cyclophosphamide-adriamycin. It should be noted that these are preliminary results and further study is necessary.
