Crooked Hillary and Dumb Trump
Authors: Hoffmann Christian R. 
Published: May 2018

AbstractWhile there is extensive research on the language of twitter, our knowledge of the pragmatics of particular twitter genres (and sub-genres) is still piecemeal. At the same time, in the past decades, political discourse analysis has widened our understanding of how language can be used instrumentally to alter or manipulate public interaction, meanings and opinions. However, it has seldom examined the evaluative load of political communication in much detail. To this end, the paper, on the one hand, serves to illuminate the pragmatics of political tweets as a twitter genre. On the other hand, the study brings to the fore the strategic use of negative evaluations in political online campaigning and discusses its potential (and actual) socio-political ramifications. The quantitative and qualitative analysis of negative evaluations largely draws on Martin and White’s Appraisal framework (2005) and is based on a compatible study byCabrejas-Peñuelas and Díez-Prados (2014). I track down, classify and categorize the negative evaluations of a subset of twitter posts by Donald Trump and Hillary Clinton in a self-compiled corpus of 1965 tweets, with a view to evaluation types, their relative frequencies and dispersion across the corpus, as well as objects and targets of evaluation. The quantitative analysis is then completed by a qualitative examination of the objects and targets of evaluation in both twitter profiles as well as a closer look at the recurrent language used to evaluate the political “other”. The results show that Trump makes more flexible (and strategic) use of negative evaluations (both in terms of types, frequency and distribution), while Clinton’s negative evaluations are less frequent, less diverse and, thus possibly, less convincing.
Self-praise online and offline
Authors: Dayter Daria 
Published: May 2018

AbstractIn contrast to the assumptions of linguistic research on face-to-face interaction, CMC studies have shown that self-promotion is acceptable and even desired in certain online contexts. However, investigations of self-praise online repeatedly refer to the specific features of internet environment or internet communities that cause a temporary suspension of the constraint against self-praise. The constraint itself is treated as somewhat of an axiom. The assumption is, therefore, that the speech act of self-praise is face-threatening and disruptive and can only occur when certain conditions prevail, for example, when a disclaimer #humblebrag is provided. In the present study, I look at self-praise in private WhatsApp chats. Until now, self-praise has been investigated in broadcasting contexts of Twitter and Instagram. On the basis of the existing description of these naturally occurring episodes of self-praise, a retrieval strategy is developed to identify self-praise in a corpus through queries for collocations of lexical markers. An analysis of the episodes of self-praise retrieved from the WhatsApp corpus and some preliminary results from the corpus of spoken American English support the tentative hypothesis that self-praise is an unmarked speech behaviour that is a part of an everyday speech act repertoire. The existing claim about its special status could be explained through a combination of intuitive assumptions carried over from the influential studies of the pre-corpus era, and the retrieval methods that targeted the modified self-praise.
Aponeurosis behaviour during muscular contraction: A narrative review
Authors: Raiteri Brent James 
Published: May 2018

AbstractThere is an abundance of evidence that suggests elastic tendons can enhance both animal and human muscle performance. However, in many terrestrial animals, including humans, a large proportion of the elastic tissue within the muscle‐tendon unit is located within the muscle. This continuous elastic sheet, which provides muscle fibre attachment, is known as the aponeurosis. The aponeurosis has a much more complicated shape than the free tendon and it undergoes a more complicated loading regime during contraction, due to its relationship with the bulging muscle fibres, which remain isovolumetric during force production. Muscle contraction may dynamically modulate the stiffness of the aponeurosis at the same active versus passive force, by increasing the intramuscular pressure and transverse forces within the muscle, which may stretch the aponeurosis in width and subsequently reduce its longitudinal strain. Some evidence also suggests that the aponeurosis mechanical properties may be affected by muscle length, which appears to reduce the fascicle strains for a given muscle force at longer muscle lengths. This narrative review outlines the animal and human studies that have investigated aponeurosis behaviour during contraction and discusses how an elastic sheet with a variable stiffness under activation might be beneficial for muscle performance. While it is clear that our understanding of the role of aponeurosis is lacking, it is hoped that further work will attempt to determine how this tissue contributes to power amplification and elastic energy savings during locomotion and potentially uncover how aponeurosis behaviour contributes to injury risk.
The Portuguese stakeholders’ perspective on social investment and quality assessment in LTC
Authors: Lopes Alexandra , Dias Isabel 
Published: May 2018

AbstractThere has been quite a considerable amount of debate over the last decade about the importance of quality assessment in the field of LTC provision in Portugal, framed by the discourse on social investment. In a context of limited resources, care providers are pressured to demonstrate creation of value. Quality assessment becomes one of the paths to demonstrate worthiness. This, however, has not translated into standardised protocols of evaluation of impacts and quality in particular. The question has been asked why is that? In this article we contribute to answering this question by looking at the discourses of stakeholders on the topic of social investment and quality in LTC. Overall there is a discourse that acknowledges the importance of assessing investments and quality as a reliable proxy to measure return on investments, although there is a general difficulty in translating social investment and the quest for quality into specific examples and tools.
Intra-Areolar Pexy: The “Compass Rose” Suture Technique for Small and Moderate Areola Herniation
Authors: Ionescu Radu , Dima Daniel , Antohi Nicolae 
Published: May 2018

Abstract

Background
Common methods for addressing minor tuberous breast (type 0; normal mammary base breast with isolated areolar herniation) do not solve the underlying pathology and may leave an unsightly scar.

Objectives
To assess the efficacy and safety of a simple, scarless method based on a novel “compass rose” technique, which addresses the etiology of minor tuberous breast and other cases desiring small areolar diameter reductions.

Methods
The technique uses 3 layers of suturing, 1 in a compass pattern and 2 in round block. Retrospective data are provided for 77 consecutive women (141 breasts) undergoing cosmetic breast augmentation surgery and requiring unilateral or bilateral type 0 tuberous breast correction (n = 22) or areolar width reduction ≤ 15 mm (n = 55).

Results
Baseline mean age and body mass index were 29.7 ± 6.0 years and 19.4 ± 1.5 kg/m2, respectively. Patients were followed up for a mean of 27.2 ± 19.5 months. In tuberous breast, mean Northwood Index decreased from 0.55 ± 0.06 at baseline to 0.36 ± 0.02 at ≥ 6 months post surgery, indicating minimal residual deformity. In areolar width reductions without tuberosity, mean width decreases of 11.3 ± 1.8 mm (20.0%) were achieved. Patient satisfaction was high with regard to lack of scarring, stability of the result, and overall breast attractiveness. Eight complications were recorded (n = 2 superficial hematoma; n = 3 hypersensibility; n = 2 knot palpability; n = 1 recurrence); all were resolved.

Conclusions
The method is effective and safe, and may be applicable across patients with type 0 tuberous breast or desiring small areolar diameter reductions.

Abstract

BACKGROUND
The optimal timing of corticosteroid (CS) treatment in patients with primary central nervous system (CNS) lymphoma (PCNSL) remains controversial. While poor clinical presentation may justify early treatment with CS, this may ultimately result in reduced concentrations of chemotherapeutic agents via perturbations in the permeability of the blood-brain barrier.

OBJECTIVE
To investigate whether early CS exposure is associated with beneficial outcomes and/or reduced occurrence of adverse events as opposed to delayed/concomitant administration.

METHODS
Herein we performed a retrospective observational analysis using patients that were prospectively entered into a database. All patients whom were admitted to the University Hospital between 2009 and 2015 with newly diagnosed PCNSL were included within our study.

RESULTS
Our cohort included 50 consecutive patients diagnosed with PCNSL; of these, in 30 patients CS administration was initiated prior to chemotherapy (early), whilst in the remaining 20 patients CS administration was initiated concomitantly with their chemotherapeutic regimen (concomitant). Within the early vs concomitant CS administration groups, no significant differences were observed with regard to progression-free survival (PFS) (P = .81), overall survival (OS) (P = .75), or remission (P = .68; odds ratio 0.76 and confidence interval [95%] 0.22-2.71). Critically, the timing of CS initiation was not associated with either PFS (P = .81) or PFS (P = .75).

CONCLUSION
Early CS administration was not associated with a deterioration in response to chemotherapy, PFS, or OS. As such, administration of CS prior to initiation of chemotherapy is both reasonable and safe for patients with newly diagnosed PCNSL.

Abstract
Chronic meningitis caused by Sporothrix sp. is occasionally described in immunosuppressed patients. We report the challenges in diagnosing and managing 2 nonimmunocompromised patients with hydrocephalus and chronic meningitis caused by Sporothrix brasiliensis. This more virulent species appears to contribute more atypical and severe cases than other related species.
Direct Cervical Carotid Stenting and Angioplasty of Right Internal Carotid Artery and Brachiocephalic Artery Ostial Stenoses With Flow Reversal: 2-Dimensional Operative Video
Authors: Rangel-Castilla Leonardo , Levy Elad I , Siddiqui Adnan H 
Published: May 2018

Abstract
We present a case of tandem stenosis of the great vessels (cervical internal carotid artery [ICA] and brachiocephalic trunk ostium [BTO]) treated with stenting and balloon angioplasty of both lesions under flow arrest. A 70-yr-old woman with a history of hypertension, hyperlipidemia, coronary artery disease, and previous strokes presented with recurrent transient ischemic attacks of the left upper and lower extremities over the last 6 mo. She underwent right cervical endarterectomy (CEA) 16 yr prior. Neurological examination was unremarkable. Carotid Doppler ultrasonography revealed severely increased velocities of the right ICA. Cervical magnetic resonance angiography demonstrated 80% right ICA stenosis and 50% BTO stenosis. Digital subtraction cerebral angiography showed 80% right ICA stenosis and 70% BTO stenosis. The patient was not a candidate for standard carotid artery stenting because the BTO precluded endovascular access or for CEA because of the previous CEA; therefore, direct carotid access and flow reversal was an alternative. Under general anesthesia and systemic heparinization, the patient underwent right carotid artery surgical exposure. Under flow reversal using the Enroute System (Silk Road Medical, Sunnyvale, California), anterograde right ICA stenting angioplasty and retrograde BTO stenting and angioplasty were performed. Successful revascularization of the right ICA and BTO was obtained. No procedure-related complications occurred. The patient was discharged home 2 d postprocedure, neurologically intact. Direct carotid access with flow reversal is a safe and effective therapeutic alternative for patients with ICA (or common carotid artery) stenosis who cannot undergo CEA or when endovascular access from the aortic arch is not possible.
Patient consent was obtained prior to performing the procedure. Institutional board approval is not required for the report of a single case.
Local Policing in a Nationalized Police Force: A Study on the Local Teams of The Netherlands’ National Police
Authors: Terpstra Jan 
Published: May 2018

Abstract
This article concentrates on the local consequences of the introduction of the Netherlands’ National Police. Six local teams of the National Police were studied, using both interviews with officers and observations of police work. Despite the emphasis on standardization, this study showed that there are important differences between these teams. The scale enlargement of the local teams resulted in several negative side effects, such as an increase in driving time of patrol cars in rural areas, and a loss of social bonds between officers in these teams. The aim to replace traditional patrol work by problem-oriented types of policing is hardly realized in practice. Despite the emphasis on the importance of community policing, in fact community officers now have a more isolated position. The introduction of the National Police created more distance between citizens and the police and made that this relationship is now more dependent on abstract forms of communication.
Extracontextuality and extravalence in quantum mechanics
Authors: Auffèves Alexia , Grangier Philippe 
Published: May 2018

We develop the point of view where quantum mechanics results from the interplay between the quantized number of ‘modalities’ accessible to a quantum system, and the continuum of ‘contexts’ that are required to define these modalities. We point out the specific roles of ‘extracontextuality’ and ‘extravalence’ of modalities, and relate them to the Kochen–Specker and Gleason theorems.

Quantum reversibility is relative, or does a quantum measurement reset initial conditions?
Authors: Zurek Wojciech H. 
Published: May 2018

I compare the role of the information in classical and quantum dynamics by examining the relation between information flows in measurements and the ability of observers to reverse evolutions. I show that in the Newtonian dynamics reversibility is unaffected by the observer’s retention of the information about the measurement outcome. By contrast—even though quantum dynamics is unitary, hence, reversible—reversing quantum evolution that led to a measurement becomes, in principle, impossible for an observer who keeps the record of its outcome. Thus, quantum irreversibility can result from the information gain rather than just its loss—rather than just an increase of the (von Neumann) entropy. Recording of the outcome of the measurement resets, in effect, initial conditions within the observer’s (branch of) the Universe. Nevertheless, I also show that the observer’s friend—an agent who knows what measurement was successfully carried out and can confirm that the observer knows the outcome but resists his curiosity and does not find out the result—can, in principle, undo the measurement. This relativity of quantum reversibility sheds new light on the origin of the arrow of time and elucidates the role of information in classical and quantum physics. Quantum discord appears as a natural measure of the extent to which dissemination of information about the outcome affects the ability to reverse the measurement.

The quantum theory of time, the block universe, and human experience
Authors: Vaccaro Joan A. 
Published: May 2018

Advances in our understanding of the physical universe have dramatically affected how we view ourselves. Right at the core of all modern thinking about the universe is the assumption that dynamics is an elemental feature that exists without question. However, ongoing research into the quantum nature of time is challenging this view: my recently introduced quantum theory of time suggests that dynamics may be a phenomenological consequence of a fundamental violation of time reversal symmetry. I show here that there is consistency between the new theory and the block universe view. I also discuss the new theory in relation to the human experience of existing in the present moment, able to reflect on the past and contemplate a future that is yet to happen.

Dealing with indistinguishable particles and their entanglement
Authors: Compagno Giuseppe , Castellini Alessia , Lo Franco Rosario 
Published: May 2018

Here, we discuss a particle-based approach to deal with systems of many identical quantum objects (particles) that never employs labels to mark them. We show that it avoids both methodological problems and drawbacks in the study of quantum correlations associated with the standard quantum mechanical treatment of identical particles. The core of this approach is represented by the multiparticle probability amplitude, whose structure in terms of single-particle amplitudes we derive here by first principles. To characterize entanglement among the identical particles, this new method uses the same notions, such as partial trace, adopted for non-identical ones. We highlight the connection between our approach and second quantization. We also define spin-exchanged multipartite states which contain a generalization of W states to identical particles. We prove that particle spatial overlap plays a role in the distributed entanglement within multipartite systems and is responsible for the appearance of non-local quantum correlations.

Recent interest in quantum communications has stimulated great technological progress in satellite quantum technologies. These advances have rendered the aforesaid technologies mature enough to support the realization of experiments that test the foundations of quantum theory at unprecedented scales and in the unexplored space environment. Such experiments, in fact, could explore the boundaries of quantum theory and may provide new insights to investigate phenomena where gravity affects quantum objects. Here, we review recent results in satellite quantum communications and discuss possible phenomena that could be observable with current technologies. Furthermore, stressing the fact that space represents an incredible resource to realize new experiments aimed at highlighting some physical effects, we challenge the community to propose new experiments that unveil the interplay between quantum mechanics and gravity that could be realizable in the near future.

Cooperative induction of ordered peptide and fatty acid aggregates
Authors: Bomba Radoslaw , Kwiatkowski Witek , Riek Roland , Greenwald Jason 
Published: May 2018

AbstractInteractions between biological membranes and disease-associated amyloids are well documented and their prevalence suggests that an inherent affinity exists between these two distinct molecular assemblies. Within the framework of our research project on amyloids and the origins of life, we hypothesized here that such interactions could increase both the sequence and structure space of peptide amyloids in a heterogeneous system and that if cooperative in nature, the interaction could be advantageous to the propagation of these entities in a prebiotic context. Thus, we have investigated the interplay between vesicle-forming fatty acids and amyloidogenic peptides, the respective precursors of lipids and proteins. Individually they are able to form ordered structures under a limited range of conditions with the bilayer of fatty acid vesicles and the cross-β core of amyloids both being repetitive structures that could in principle support a cooperative interaction. Here we report that an 8-residue basic peptide that can form an amphipathic β-strand, that is soluble at neutral pH and that can form amyloids above its pI at pH 11, is also able to cooperatively form novel co-aggregates of diverse structure with and in the context of simple fatty acids at neutral pH. Below the critical vesicle concentration (CVC) the mixtures of fatty acid and peptide yield a flocculent precipitate with an underlying β-structure. Above the CVC, the mixtures yield ribbon or tube-like structures that bear some of the hallmarks of amyloids yet have associated with them a significant amount of fatty acids, likely in a bilayer structure. In the context of the origin of cellular life these results expand the phase space of both peptides and fatty acids while providing a simple yet robust physical connection between two distinct biological entities relevant for life.
