Composition-tunable transition metal dichalcogenide nanosheets a scalable, solution-processable method.

The alloying of two-dimensional (2D) transition metal dichalcogenides (TMDs) is an established route to produce robust semiconductors with continuously tunable optoelectronic properties. However, typically reported methods for fabricating alloyed 2D TMD nanosheets are not suitable for the inexpensive, scalable production of large-area (m) devices. Herein we describe a general method to afford large quantities of compositionally-tunable 2D TMD nanosheets using commercially available powders and liquid-phase exfoliation.

Measuring leadership an assessment of the Multifactor Leadership Questionnaire.

Although the most used measure of transformational leadership, the Multifactor Leadership Questionnaire (MLQ), has been the subject of intense scrutiny among leadership scholars, little interest has been shown in analyzing the relationship between its underlying constructs and / or their measures. The present study identifies a formative factor structure for most MLQ first-order factors, replacing the usual reflective model. We demonstrate the value of this structure using data from two different samples.

Resilient managed competition during pandemics: lessons from the Italian experience.

One of the main governance decisions that policymakers need to make is whether to implement public services via centralized or decentralized forms. As Costa et al. discuss in their article, when public services are implemented via competing systems, service providers contend to provide good services with the ultimate objective of gaining market quota.

Artificial intelligence for the public sector: opportunities and challenges of cross-sector collaboration.

Public sector organizations are increasingly interested in using data science and artificial intelligence capabilities to deliver policy and generate efficiencies in high-uncertainty environments. The long-term success of data science and artificial intelligence (AI) in the public sector relies on effectively embedding it into delivery solutions for policy implementation. However, governments cannot do this integration of AI into public service delivery on their own.

DETERMINANTS OF NETWORK OUTCOMES: THE IMPACT OF MANAGEMENT STRATEGIES.

The literature on network management is extensive. However, it generally explores network structures, neglecting the impact of management strategies. In this article we assess the effect of management strategies on network outcomes, providing empirical evidence from 119 urban revitalization networks.

Adducted vocal cords relieved by neuromuscular blocking drug: a cause of impaired mechanical ventilation when using a laryngeal mask airway: two photographically documented cases.

Two cases of vocal cord closure, which was responsible for acute intraoperative impairment of mechanical ventilation in two patients with entropy-controlled depth of anesthesia, are reported. Administration of low-dose neuromuscular blocking drug was associated with immediate vocal cord relaxation and restoration of efficient mechanical ventilation.

Preventing biofilm formation and associated occlusion by biomimetic glycocalyxlike polymer in central venous catheters.

The use of catheters and other implanted devices is constantly increasing in modern medicine. Although catheters improve patients' healthcare, the hydrophobic nature of their surface material promotes protein adsorption and cell adhesion. Catheters are therefore prone to complications, such as colonization by bacterial and fungal biofilms, associated infections, and thrombosis.

The creation of innovation through public-private collaboration.

This article develops the notion of how different options of public-private collaborations implemented by organizations affect the creation of innovation through a case study: the Blood and Tissue Bank. Data were obtained through in-depth semi-structured interviews with the entire managerial team of the organization under analysis. We coded the interviews, and implemented content analysis.

Wound healing and catheter thrombosis after implantable venous access device placement in 266 breast cancers treated with bevacizumab therapy.

The aim of this study was to determine, in a population with metastatic breast cancer treated with bevacizumab therapy, the incidence of wound dehiscence after placement of an implantable venous access device (VAD) and to study the risk of catheter thrombosis. This study enrolled all VADs placed by 14 anesthetists between 1 January 2007 and 31 December 2009: 273 VADs in patients treated with bevacizumab therapy and 4196 VADs in patients not treated with bevacizumab therapy. In the bevacizumab therapy group, 13 cases of wound dehiscence occurred in 12 patients requiring removal of the VAD (4.

Use of a subcutaneous implantable pleural port in the management of recurrent malignant pleurisy: five-year experience based on 168 subcutaneous implantable pleural ports.

Introduction: The authors report their experience in the use of subcutaneous implantable pleural port (SIPP) catheters for the treatment of symptomatic recurrent malignant pleurisy.

Materials And Methods: Single-center, prospective follow-up of 137 patients (168 SIPPs).

Results: No SIPP placement failures were observed.

Management of operable invasive breast cancer in women over the age of 70: long-term results of a large-scale single-institution experience.

Background: The treatment of choice for elderly women with breast cancer remains controversial. This retrospective analysis of a cohort from a single institution was designed to evaluate whether such patients are really undertreated because of their age and to reappraise their usual management.

Methods: The characteristics of 538 patients aged > or = 70 years with operable breast cancer, treated between 1995 and 1999, were retrospectively analyzed comparing patients aged 70 to 75 years (group I, n = 288), 75 to 80 years (group II, n = 156), and > or = 80 years (group III, n = 94).

Effects of dietary L-arginine intake on cardiorespiratory and metabolic adaptation in athletes.

To assess the effect of diet enrichment with L-arginine or supplementation at high doses on physiological adaptation during exercise, 9 athletes followed 3 different diets, each over 3 consecutive days, with a wash-out period of 4 d between training sessions: control diet (CD), 5.5 +/- 0.3 g/d of L-arginine; Diet 1 (rich in L-arginine food), 9.

Prenatal programming of sporting success: associations of digit ratio (2D:4D), a putative marker for prenatal androgen action, with world rankings in female fencers.

Associations of the second-to-fourth digit ratio (2D:4D), a putative marker for prenatal androgen action, and of absolute finger length, a putative marker for pubertal-adolescent androgen action, with sport performance were examined in a multinational sample of 87 world-class women epee fencers. Lower (masculinized) digit ratios correlated, although not significantly so, with better current and highest past world rankings. These correlations were significant for right-hand 2D:4D with controls for the most salient factors for 2D:4D (ethnicity) and world rankings (years of international experience, height, and weight).

Conservative treatments of intraocular retinoblastoma.

Objective: To describe the efficacy of conservative management of retinoblastoma by an association of conservative ocular therapies and chemothermotherapy.

Design: Phase II prospective nonrandomized trial.

Participants: Eighty-three children were included (115 eyes).

Use of a pleural implantable access system for the management of malignant pleural effusion: the Institut Curie experience.

Purpose: Malignant pleural effusion has a very poor prognosis, raises problems of medical management, and impairs quality of life. The authors report the first experience of a pleural implantable access system for the treatment of recurrent symptomatic malignant pleural effusion.

Description: Prospective follow-up of 29 patients between August 20, 2005 and August 1, 2007 in a single center.

[Specific aspects of the pre-anaesthetic consultation in patients with cancer].

This article focuses on the problems which the anaesthetist faces in the preoperative evaluation of patients with cancer and the specific aspects of this consultation. The multidisciplinary approach to the care of patients with cancer demands an understanding of all aspects of its treatment. Chemotherapy, radiotherapy and surgery are often combined and are very successful.
