Hyunsuk Hong
We consider a mean-field model of coupled phase oscillators with random heterogeneity in the coupling strength. The system that we investigate here is a minimal model that contains randomness in diverse values of the coupling strength, and it is found to return to the original Kuramoto model [Y. Kuramoto, Prog. Theor. Phys. Suppl. 79, 223 (1984)10.1143/PTPS.79.223] when the coupling heterogeneity disappears. According to one recent paper [H. Hong, H. Chaté, L.-H. Tang, and H. Park, Phys. Rev. E 92, 022122 (2015)10...

New researchers often face difficulty finding and focusing research questions. I describe a new tool for research mentoring, the Pursuing Personal Passion (P3) interview, and a systematic approach to help learners organize their curiosity and develop researchable questions aligned with their personal and professional priorities. The learner-centered P3 research interview parallels the patient-centered clinical interview. This paper reviews experience with 27 research mentees over the years 2009 to 2016, using the P3 approach to identify their initial research topics, classify their underlying passions and track the evolution into their final research questions...

The aims of this study were to design the Hookah Smoking Initiation for Women Questionnaire (HIWQ) and determine its psychometric properties. This was a sequential exploratory mixed-methods design consisting of qualitative and quantitative phases. This study was conducted from August 2012 to July 2013 in Tehran. In the qualitative phase, semi-structured interviews were held with 36 Iranian women for developing a preliminary item pool. Consequently, during the quantitative phase, the psychometric properties of the questionnaire were determined with the collaboration of 323 women living in various geographical locations in Tehran, Iran...

This review aims to be a comprehensive, authoritative, critical, and readable review of general interest to the medicinal chemistry community because it focuses on the pharmacological, chemical, structural and computational aspects of diverse chemical categories as monoamine oxidase inhibitors (MAOIs). Monoamine oxidases (MAOs), namely MAO-A and MAO-B represent an enormously valuable class of neuronal enzymes embodying neurobiological origin and functions, serving as potential therapeutic target in neuronal pharmacotherapy, and hence we have coined the term "Neurozymes" which is being introduced for the first time ever...

Patients and healthcare providers are becoming increasingly connected via social media, bringing new opportunities and challenges. Direct connection can occur between patients and providers using online tools such as Facebook and LinkedIn. In addition, providers can gather information about patients using a search engine such as Google, referred to as patient-targeted Googling (PTG). An online 54-item survey was used to gain information on (1) how and to what extent genetic counseling students and genetic counselors connect directly with patients via social media sites, and (2) gather information on providers using PTG...

Covering up to February 2017The pericarps of several species from the Zanthoxylum genus, a.k.a. the "prickly ash", have long been used for culinary purposes throughout Asia, most notably in the Sichuan (previously Szechuan) cuisine of Southwestern China, due to the unique tingling and numbing orosensations arising from a collection of polyunsaturated fatty acid amide (alkamide) constituents. The past decade has experienced dramatically increased academic and industrial interest in these pungent Zanthoxylum-derived alkamides, with a concomitant explosion in studies aimed at elucidating the specific biochemical mechanisms behind several medically-relevant biological activities exhibited by the natural products...

There has been a growing trend towards incorporating short, educational films as part of research funding and project proposals. Researchers and developers in CO2 capture and storage are using films to communicate outcomes, but such films can be influenced by experiences and values of the producers. We document the content and presentation of seven online CO2 capture and storage films to determine how framing occurs and its influence on the tone of films. The core frame presents CO2 capture and storage as a potential solution to an imminent crisis in climatic warming and lack of a sustainable energy supply...

Sibling sexual abuse (SSA) is a continuum of childhood sexual behaviors that do not fit the category of age-appropriate curiosity. Although SSA may be the most prevalent and longest lasting form of intrafamilial sexual abuse-as well as the one with the worst repercussions-it is also the least reported, studied, and treated. Based on 100 mostly religious Jewish families referred to a child advocacy center (CAC) in Jerusalem from 2010 to 2015, this qualitative study examines SSA characteristics, dynamics, and perceptions of deviancy in multisibling subsystems...

To distinguish colors, the nervous system must compare the activity of distinct subtypes of photoreceptors that are maximally sensitive to different portions of the light spectrum. In vertebrates, a variety of adaptations have arisen to refine the spectral sensitivity of cone photoreceptors and improve color vision. In this review article, we focus on one such adaptation, the oil droplet, a unique optical organelle found within the inner segment of cone photoreceptors of a diverse array of vertebrate species, from fish to mammals...

For hundreds of years, biologists have studied accessible organisms such as garden peas, sea urchins collected at low tide, newt eggs, and flies circling rotten fruit. These organisms help us to understand the world around us, attracting and inspiring each new generation of biologists with the promise of mystery and discovery. Time and time again, what we learn from such simple organisms has emphasized our common biological origins by proving to be applicable to more complex organisms, including humans. Yet, biologists are increasingly being tasked with developing applications from the known, rather than being allowed to follow a path to discovery of the as yet unknown...

The presentation and management of two bizarre congenital cephalic curiosities at the two extremes of the clinical spectrum are discussed herewith. Case 1: presented to us as a neonate with a scalp swelling mirror-imaging her head and face. The journey from clinics to wards and to the operation theatre and to her home is introspected. Case 2: presented to us as dicephalous dibrachius dipus parapagus conjoined twins. The detailed work-up of individual organ systems, the multidisciplinary approach to management and the final outcome are discussed...

PREMISE OF THE STUDY: Aspen groves along the Niobrara River in Nebraska have long been a biogeographic curiosity due to morphological differences from nearby remnant Populus tremuloides populations. Pleistocene hybridization between P. tremuloides and P. grandidentata has been proposed, but the nearest P. grandidentata populations are currently several hundred kilometers east. We tested the hybrid-origin hypothesis using genetic data and characterized putative hybrids phenotypically. METHODS: We compared nuclear microsatellite loci and chloroplast sequences of Niobrara River aspens to their putative parental species...

OBJECTIVES: We know little about women's interest in and experiences with a printout of their pre-abortion ultrasound image. METHODS: We conducted a mixed methods study at a large volume abortion-providing facility where patients are offered the opportunity to receive their ultrasound printout, using two years of abstracted medical chart data on demographics and printout acceptance and interviews with patients about whether they took a printout and, if they did, why and what they did with it...

BACKGROUND: The increasing number of legally ambiguous and precarious Novel Psychoactive Substances (NPS) constitutes a challenge for policy makers and public health. Scientific and more in-depth knowledge about the motivations for using NPS is scarce and often consist of predetermined, non-systematic, or poorly described reasons deduced from top-down approaches. Therefore, the aim of the present study was to explore and characterize the users' self-reported reasons for NPS use inductively and more comprehensively...

There is little empirical understanding of how young children's screen engagement links to their well-being. Data from 19,957 telephone interviews with parents of 2- to 5-year-olds assessed their children's digital screen use and psychological well-being in terms of caregiver attachment, resilience, curiosity, and positive affect in the past month. Evidence did not support implementing limits (< 1 or < 2 hr/day) as recommended by the American Academy of Pediatrics, once variability in child ethnicity, age, gender, household income, and caregiver educational attainment were considered...

BACKGROUND: Recruitment rates of older people in epidemiological studies, although relatively higher than in clinical trials, have declined in recent years. This study aimed to explore motivating factors and concerns among older participants in an intensive epidemiological study (Hertfordshire Sarcopenia Study - HSS) and identify those that could aid future recruitment to epidemiological studies and clinical trials. METHODS: Participants of the HSS fasted overnight and travelled several hours each way to the research facility at an English hospital for extensive diet/lifestyle questionnaires and investigations to assess muscle including blood tests and a muscle biopsy...

Manfred Eigen turned 90 on May 9th, 2017. He celebrated with a small group of colleagues and friends on behalf of the many inspired by him over his lifetime-whether scientists, artists, or philosophers. A small group of friends, because many-who by their breakthroughs have changed the face of science in different research areas-have already died. But it was a special day, devoted to the many genius facets of Manfred Eigen's oeuvre, and a day to highlight the way in which he continues to exude a great, vital and unbroken passion for science as well as an insatiable curiosity beyond his own scientific interests...

Efficient nickel transport is crucial for the survival and virulence of various bacteria and fungi, with Ni2+ being required for the activity of nine enzymes such as [NiFe] hydrogenase, which catalyzes the reversible oxidation of molecular hydrogen for energy production. This work focuses on a region of transmembrane domain I from the HupE nickel transporter, highly conserved in the HupE/UreJ and NiCoT permease families, analyzing its interactions with native Ni2+ and two other metal ions (Cu2+ and Zn2+), which might interfere with nickel binding...

The investment theory of adult intelligence posits that individual differences in knowledge attainment result from people's differences in cognitive ability and their propensity to apply and invest that ability, which is referred to as investment personality traits. Here, we differentiated intellectual (i.e., intellectual curiosity) and nonintellectual investment (i.e., openness to experience), and we tested their respective predictive validity for knowledge attainment in four independent lab-based studies (overall N = 649)...
