Длительность интереса жителей США к террористическим актам: зависит ли она от политических взглядов?
Authors: Подлипская Ольга Геннадьевна 
Published: March 2022

В работе исследуется динамика общественного внимания к террористическим актам, произошедшим в США в 2012—2020 гг., в зависимости от политических предпочтений населения штата. Из 7 включенных в рассмотрение террористических атак 5 были совершены радикальными исламистами, одна — правым экстремистом, одна не имела политической направленности. В качестве независимой переменной используется процент голосов, полученный республиканским кандидатом в данном штате на выборах, ближайших к дате события (рассматриваются выборы 2020, 2016 и 2012 гг.). Изучается динамика количества онлайн-запросов, сделанных на тему конкретного теракта пользователями из данного штата в поисковой системе Google. Данные получены с помощью сервиса Google Trends. В качестве меры спада интереса к событию используется отношение числа запросов в первые два дня после события, к числу запросов в четвертый и пятый дни. Исходная гипотеза исследования состоит в том, что теракт, совершенный правым экстремистом, будет дольше удерживать общественное внимание в демократических штатах, а теракт радикальных исламистов — в республиканских. Результаты подтвердили первую часть гипотезы, однако оказались неоднозначными в отношении второй части. Внимание к исламистским терактам удерживалось дольше в демократических штатах (в меньшей мере, чем для теракта правого экстремиста), однако для четырех из рассмотренных в работе терактов корреляция внимание с политической позицией штата оказалась статистически незначимой. Теракт, не имеющий политической направленности, значимо дольше удерживал общественное внимание в республиканских штатах. Таким образом, по спаду общественного внимания теракты дифференцируются в первую очередь не по линии «исламистские — расистские», а по линии «политически мотивированные — не политически мотивированные». Возможное объяснение полученных результатов состоит в том, что демократы более склонны к обсуждению политических вопросов в целом.

Measuring and assessing indeterminacy and variation in the morphology-syntax distinction
Authors: Tallman Adam J. R. , Auderset Sandra 
Published: March 2022

Abstract
We provide a discussion of some of the challenges in using statistical methods to investigate the morphology-syntax distinction cross-linguistically. The paper is structured around three problems related to the morphology-syntax distinction: (i) the boundary strength problem; (ii) the composition problem; (iii) the architectural problem. The boundary strength problem refers to the possibility that languages vary in terms of how distinct morphology and syntax are or the degree to which morphology is autonomous. The composition problem refers to the possibility that languages vary in terms of how they distinguish morphology and syntax: what types of properties distinguish the two systems. The architecture problem refers to the possibility that languages vary in terms of whether a global distinction between morphology and syntax is motivated at all and the possibility that languages might partition phenomena in different ways. This paper is concerned with providing an overarching review of the methodological problems involved in addressing these three issues. We illustrate the problems using three statistical methods: correlation matrices, random forests with different choices for the dependent variable, and hierarchical clustering with validation techniques.

Abstract
Driven by new two-dimensional materials, great changes and progress have taken place in the field of ultrafast photonics in recent years. Among them, the emerging single element two-dimensional materials (Xenes) have also received much attention due to their special physical and photoelectric properties including tunable broadband nonlinear saturable absorption, ultrafast carrier recovery rate, and ultrashort recovery time. In this review, the preparation methods of Xenes and various integration strategies are detailedly introduced at first. Then, we summarize the outcomes achieved by Xenes-based (beyond graphene) fiber lasers and make classifications based on the characteristics of output pulses according to the materials characterization and nonlinear optical absorption properties. Finally, an outlook of the future opportunities and challenges of ultrafast photonics devices based on Xenes and other 2D materials are highlighted, and we hope this review will promote their extensive applications in ultrafast photonics technology.

A review of atomic layer deposition modelling and simulation methodologies: Density functional theory and molecular dynamics
Authors: Sibanda David , Oyinbo Sunday Temitope , Jen Tien-Chien 
Published: March 2022

AbstractThe use of computational modelling and simulation methodologies has grown in recent years as researchers try to understand the atomic layer deposition (ALD) process and create new microstructures and nanostructures. This review article explains and simplifies two simulation methodologies, molecular dynamics and the density functional theory (DFT), in solving atomic layer deposition problems computationally. We believe that these simulation methodologies are powerful tools that can be utilised in atomic layer deposition. DFT is used to solve problems in surface science and catalysis (predicting surface energy, adsorption energy, charge transfer,etc.), semiconductors (band structure, defect bands, band gap,etc.), superconductors (electron–phonon coupling, critical transition temperature), and molecular electronics (conductance, current–voltage characteristics). Molecular dynamics (MD) is used to predict the kinetic and thermodynamic properties of a material. Of interest in this article is a review where different material problems emanating from atomic layer deposition from these fields have been addressed by DFT and MD. Selected publications are discussed where DFT and MD have been successfully applied in atomic layer deposition (and related processes in some instances). The applications of DFT stretch from binding energy calculations of molecules and the solid band structure in chemistry and physics, respectively, computing the electron density up to determining the properties of a many-electron system. Also highlighted in this review study are the challenges that DFT and MD simulations must overcome.

Abstract
In this study, chemical modification of chitosan has been carried out using epichlorohydrin as crosslinking agent and ethyl acetoacetate as a modifier to graft acetoacetyl moiety. The said organo-functionalization on chitosan and sodium alginate not only offered a novel support for TiO2 immobilization but also enhanced sorption performance for Ni(II) recovery from aqueous medium. So, a composite consisting of acetoacetyl moiety grafted chitosan, sodium alginate and titanium oxide (EAA-MCS/TiO2) was prepared and characterized by fourier transform-infra red (FT-IR) spectroscopy and scanning electron microscopy (SEM). The hybrid composite (3EAA-MCS/TiO2) which had TiO2 to EAA-MCS mass ratio of 20.0% by weight showed maximum sorption efficiency. The formulated sorbent was conditioned in the form of hydrogel beads for operation. Isothermal sorption and kinetics studies were performed at pH = 6.0 to configure the nature of sorption. Pseudo-2nd order rate expression better explained the sorption kinetics and chemisorption is the predominant mode of uptake. Langmuir adsorption model better explained the sorption process (R
2 ∼ 0.99) and maximum monolayer sorption capacity (q

m
) at sorption/desorption dynamic equilibrium was computed as 403 mg/g at optimized pH.
Ectopic Cushing’s syndrome from an ACTH-producing pheochromocytoma with a non-functioning pituitary adenoma

Published: March 2022

Summary
An adrenocorticotropic hormone (ACTH)-producing pheochromocytoma (PCC)/paraganglioma is the cause of ectopic Cushing’s syndrome (CS) in 5.2% of cases reported in the literature. We present a previously healthy 43-year-old woman admitted to our hospital with cushingoid features and hypertensive urgency (blood pressure = 200/120 mmHg). Her 24-h urinary free cortisol was >4270 nmol/day (reference range (RR) = 100–380 nmol/day) with a plasma ACTH of 91.5 pmol/L (RR: 2.0–11.5 pmol/L). Twenty-four-hour urinary metanephrines were increased by 30-fold. Whole-body CT demonstrated a 3.7-cm left adrenal mass with a normal-appearing right adrenal gland. Sellar MRI showed a 5-mm sellar lesion. MIBG scan revealed intense uptake only in the left adrenal mass. She was managed pre-operatively with ketoconazole and phenoxybenzamine and underwent an uneventful left laparoscopic adrenalectomy, which resulted in biochemical resolution of her hypercortisolemia and catecholamine excess. Histology demonstrated a PCC (Grading System for Adrenal Pheochromocytoma and Paraganglioma score 5) with positive ACTH staining by immunohistochemistry. A PCC gene panel showed no mutations and there has been no evidence of recurrence at 24 months. This case highlights the difficult nature of localizing the source of CS in the setting of a co-existing PCC and sellar mass.

Learning points

An adrenocorticotropic hormone (ACTH)-producing pheochromocytoma (PCC) is an important item to be considered in all patients presenting with ectopic Cushing’s syndrome (CS).

In exceptionally rare cases, patients with ectopic CS may present with multiple lesions, and a systematic approach considering all potential sources is crucial to avoid misdiagnosis.

CS with a large adrenal mass but lacking contralateral adrenal atrophy should raise suspicion of an ACTH-dependent process.

In patients with clinical suspicion of PCC, clinicians should be mindful of the use of steroids and beta-blockers without appropriate alpha blockade as they may precipitate an adrenergic crisis.

Analysis of Timely Access to Healthcare and Difficulty Procuring Specialist Care Among Children with and without Anxiety or Depression Disorders
Authors: Wu Jingwei , Paoletti Andrew , DeLago Cynthia 
Published: March 2022

Background: To examine disparities to access preventive care and specialist care in children with anxiety or depression disorders.
Methods: The population of interest was extracted from the National Survey of Children’s Health 2011/2012 (NSCH 2011/12) data set. The sample included children (0-17 years old) and their caregivers who completed the survey. Data were analyzed from February 2011 to June 2012. Outcome variables included reports for missed or delayed care, and problems procuring specialist care based on parental response to interview questions. Covariates included child/caregiver demographics, insurance status, household employment, and poverty levels.
Findings: A total of 85 536 records were extracted from the NSCH 2011/12 data set. The covariate-adjusted odds (also adjusted as necessary using the correct sampling methods suggested by the NSCH) of having delayed or missed care for a child with anxiety or depression were 2.26 (95% confidence interval [CI], 1.83-2.79, p<0.001) times higher than a child without anxiety or depression. The covariate-adjusted odds of the caregiver reporting problems procuring specialist care for a child with anxiety or depression were 1.66 (95% CI, 1.45-1.88, p<0.001) times higher than a child without these diagnoses.
Conclusions: Children with anxiety or depression are less likely to obtain timely preventive care and have problems procuring specialist care. These findings highlight a disparity that requires the attention of healthcare providers and outreach programs.

Published: March 2022

Background and aim. Osteoarthritis (OA) is the most common joint condition and the leading cause of pain and disability in elderly patients. Currently, there is no biomarker available for the early diagnosis of OA, and limited data is available regarding the molecular basis of progression for OA. For this reason, this study aimed to identify the metabolomic profile of early and late OA using high-performance liquid chromatography coupled with untargeted mass spectrometry (LC-MS).
Methods. 31 patients with knee OA and joint effusion were enrolled. Based on Kellgren/Laurence scale, 12 patients were classified as early OA (eOA) and 19 as late OA (lOA). The synovial fluid (SF) was collected and characterized by untargeted LC-MS. Only the metabolites identified in more than 25% of each group were kept for further analysis. Principal component analysis (PCA) enabled the unsupervised clustering of the eOA and lOA groups. Further, for classification, the best three principal components (PCs) were used as input for two machine learning algorithms (random forest and naïve Bayes), which were trained to discriminate between the eOA and lOA groups.
Results. 43 metabolites were identified in both eOA and lOA, but after selecting the metabolites present in at least 25% of the patients in each group, the metabolomics analysis yielded a panel of only nine metabolites: four metabolites related to phospholipids (phosphatidylcholine 20:0/18:2 and 18:0/20:2, sphingomyelin, and ceramide), three metabolites belonging to purine metabolites (inosine 5'-phosphate, adenosine thiamine diphosphate, and diadenosine 5',5'-diphosphate), one metabolite was a gonadal steroid hormone (estrone 3-sulfate), and one metabolite represented by heme, with all but ceramide (d18:1/20:0) being enriched in the lOA group. By using as features the best three PCs (PC2, PC8 and PC9), random forest and naïve Bayes machine learning algorithms yielded a classification accuracy of 0.81 and 0.78, respectively.
Conclusion. Our LC-MS analysis of SF from patients with eOA and lOA indicates stage-dependent differences, lOA being associated with a perturbed metabolome of phospholipids, purine metabolites, gonadal steroid hormones (estrone 3-sulfate) and a heme molecule. Specific questions need to be answered regarding the biosynthesis and function of these metabolites in osteoarthritic joints, with the aim of developing new relevant biomarkers and therapeutic strategies.

Neolitik yaşam biçiminin ortaya çıkışı ve gelişimi açısından, Güneydoğu Anadolu Bölgesi’nin önemi tartışılmaz bir gerçek olarak önümüzde durmaktadır. Bu bölge içinde Geç PPNA ve Erken PPNB döneme tarihlenen çok az yerleşim yerinde kazı yapılmıştır. Bunlardan biri, Yukarı Dicle havzasının kuzey kesiminde, Ambar Çayı’nın batı kıyısına kurulmuş olan Gre Fılla yerleşimidir. Bu yazıda Gre Fılla’da 2018-2019 kazılarında ele geçen kesici kenarlı sürtme taş aletler ele alınmıştır. Bu tür aletler, sürtme taş buluntu topluluğu içinde tanımlı bir alet grubunu oluşturmaktadır. Toplam 26 adet buluntunun her biri öncelikle metrik ölçüleri, kullanılan hammaddeler, üretim teknikleri, tipolojileri ve yerleşim içindeki buluntu yerleri bağlamında ele alınmıştır. Gre Fılla kesici sürtme taş aletleri, üretiminde kullanılan hammaddeler ve boyutları bakımından büyük bir çeşitlilik sunmaktadır. Bunlardan elde edilen veriler diğer buluntulardan elde edilen verilerle birlikte değerlendirilmiştir.
Bu aletler üzerinde yürütülen analizlerden elde edilen veriler bölge içinde kazıları yapılmış çağdaşı yerleşmelerin verileriyle karşılaştırılmıştır. Yakındoğu’nun neredeyse tüm yerleşmelerinde Çanak Çömleksiz Neolitik Dönem boyunca yaygın olarak gözlemlenen bu aletler üzerine ayrıntılı analizler çok sınırlı yapılmış olup, kullanılan terminoloji de büyük ölçüde farklılık göstermektedir. Gre Fılla kazılarından elde edilen bulgular bölgenin kültür tarihine önemli katkılar sağlamaktadır.
La plasmación constitucional de los derechos humanos: un punto de encuentro en defensa de la Constitución = Constitutional rendering of human rights: A meeting point in defense of the Constitution
Authors: Alegre Martínez Miguel Ángel 
Published: March 2022

El artículo 10.2 de la Constitución española de 1978, además de ser el punto de encuentro entre los niveles internacional e interno del reconocimiento de los derechos, sirve en este artículo como punto de partida para repasar algunas cuestiones básicas sobre lo que la Constitución aporta como norma básica del ordenamiento (articulación y cohesión del mismo, racionalización y limitación del poder, fuente de validez de las demás normas), y lo que exige como instrumento destinado a organizar la comunidad política en torno a determinados valores (libertad, igualdad, democracia, transparencia, certeza, respeto a la dignidad y a los derechos, etc.). A propósito de todo ello, se mencionan algunos retos actuales a los que se enfrentan los poderes constituidos para favorecer el desarrollo de la persona de modo conforme a la dignidad que la Constitución reclama. Article 10.2 of the 1978 Spanish Constitution, besides being the meeting point between the international and internal levels of the recognition of rights, serves in this contribution as a starting point to review some basic questions about what provides the Constitution as basic norm of the juridical system, (its articulation and cohesion, rationalization and limitation of power, source of validity of the other norms) and what it requires as an instrument for organizing the political community around certain values (freedom, equality, democracy, transparency, certainty, respect for dignity and rights, etc.). Also are mentioned, regarding all this, some current challenges faced by constituted powers, in order to favor the development of person in accordance with the dignity that the Constitution demands.
Libertad de expresión de las convicciones personales y el derecho al honor = Freedom of expression of personal convictions and the right to hono
Authors: De la Fuente García Selene 
Published: March 2022

Nuestro estado democrático de derecho, junto a la actual Constitución, confiere a los ciudadanos una serie de derechos fundamentales, como son la libertad de conciencia, el derecho a la libertad de expresión y el derecho a la libertad de información, los cuales gozan de una máxima protección. El pleno ejercicio de dichos derechos permite al sujeto el libre desarrollo de su personalidad, uno de los principios constitucionales más relevantes. Estos derechos fundamentales cuentan, además, con la fortaleza que les confiere la figura de la garantía institucional ya que son idóneos para la creación de la opinión pública libre. El desarrollo de ellos deberá darse acorde al orden público protegido por la ley, y en concreto, con el respeto a otros derechos fundamentales, en especial el derecho al honor. En la práctica, la colisión entre la libertad de expresión y el derecho al honor suele ser bastante habitual. La jurisprudencia constitucional establece una serie de reglas para resolver este conflicto, que será objeto de estudio de esta investigación. Our democratic rule of law, together with the current Constitution, confers on citizens a number of fundamental rights, such as freedom of conscience, the right to freedom of expression and the right to freedom of information, which enjoy maximum protection. The full exercise of these rights allows the subject to freely develop his personality, one of the most relevant constitutional objects. These fundamental rights also have the strength afforded to them by the institutional guarantee figure as they are suitable for the creation of free public opinion. The development of them should be in accordance with the public order protected by law, and in particular with respect for other fundamental rights, in particular the right to honour. In practice, the collision between freedom of expression and the right to honour is often quite common. Constitutional jurisprudence lays down a number of rules for resolving this conflict, which will be the subject of study of this investigation
