Published: September 2021

Traditional methods for mitigating pandemics employ a dual strategy of contact tracing plus testing combined with quarantining and isolation. The contact tracing aspect is usually done via manual (human) contact tracers, which are labor-intensive and expensive. In many large-scale pandemics (e.g., COVID-19), testing capacity is resource limited, and current myopic testing strategies are resource wasteful. To address these challenges, in this work, we provide a blueprint on how to contain the spread of a pandemic by leveraging wireless technologies and advances in sequential learning for efficiently using testing resources in order to mitigate the spread of a large-scale pandemic.
We study how different wireless technologies could be leveraged to improve contact tracing and reduce the probabilities of detection and false alarms. The idea is to integrate different streams of data in order to create a susceptibility graph whose nodes correspond to an individual and whose links correspond to spreading probabilities. We then show how to develop efficient sequential learning based algorithms in order to minimize the spread of the virus infection. In particular, we show that current contact tracing plus testing strategies that are aimed at identifying (and testing) individuals with the highest probability of infection are inefficient. Rather, we argue that in a resource constrained testing environment, it is instead better to test those individuals whose expected impact on virus spread is the highest. We rigorously formulate the resource constrained testing problem as a sequential learning problem and provide efficient algorithms to solve it. We also provide numerical results that show the efficacy of our testing strategy.

Published: September 2021

Canlılar içinde bulundukları mekanı duyularının yanı sıra beden hareketleri ile deneyimlemektedir. Bu nedenle, ‘mimarlık’, ‘hareket’ ve ‘beden’ kavramlarının arasında güçlü bir ilişki bulunmaktadır. Beden ve hareket verilerinin mimari form yaratma sürecinde etkin bir biçimde kullanılması tasarımı ve tasarımcıyı besleyen bir süreçtir. Dolayısıyla bu verilerin tasarım sürecine aktarılması adına izlenebilecek yöntemlerin ve ifade tekniklerinin araştırılması önemlidir.
Bu bağlamda ....... Üniversitesi 4. sınıf iç mimarlık öğrencisi 19 kişi ile birlikte bir çevrimiçi çalıştay gerçekleştirilmiş ve sunduğu hareket çeşitliliği gözetilerek seçilen bir ‘dans’ performansı form üretim aracı olarak ele alınmıştır. Kompleks bir tasarım problemi olarak kurgulanabilecek form üretim süreci bu çalışmada bağlamlarından sıyrılarak salt dans geometrisine dayalı üretim teşvik edilmiştir. Böylece ‘hareketin geometrisi’ olarak tanımlanan ‘Kinematik’ çalıştay başlığının önerdiği gibi dans performansı anlam ve etkiyen güçlerden arındırılarak yalnızca bedensel hareketten oluşan formlar aranmıştır. İki fazlı kurgulanan çalışmanın birinci fazında katılımcılara yaklaşık bir dakikalık dans videosu izletilmiş ve izlenen performansın kısa-süreli hafızaya dayalı olarak üç boyutlu model ile temsil edilmesi istenmiştir. Çalışmanın ikinci fazında video tekrarlı olarak oynatılırken temsilin tekrarlanması beklenmiş ve sonuç ürünler Laban Hareket Analizi yöntemi ile analiz edilmiştir. Katılımcıların geribildirimleri metin, anket ve sözel açıklamalar ile toplanmış ve nitel veri analizi gerçekleştirilmiştir. İki fazın sonuç ürünleri arasında görsel canlandırmaya, malzeme seçimine ve yoruma bağlı farklılıklar tespit edilmiş ve etkileri tartışılmıştır.

Iatrogenic scleroderma renal crisis: A case report and mini literature review for renal crisis
Authors: Boz Gülşah , Karahan Samet , Yüksek Nurdan 
Published: September 2021

Background: Systemic sclerosis is a connective tissue disease characterized by fibrosis of the skin and organs, marked changes in microvascular structure, cellular and humoral immune disorders. Renal involvement is more frequent and mainly characterized by moderate proteinuria, elevated serum creatinine levels, and hypertension. The most common kidney involvement in SSc is scleroderma renal crisis (SRC) that is fatal without prompt intervention.Case report: A 52-year-old Caucasian male with known diffuse cutaneous systemic sclerosis was hospitalized with communityacquired pneumonia. On the fifth day after appropriate antibiotic therapy and 60 mg/day methylprednisolone, decreased urine output, arterial hypertension, decreased renal function and pulmonary edema developed. The patient was diagnosed with a scleroderma renal crisis. Emergency hemodialysis was applied to the patient, and captopril 6 × 25 mg/day and nifedipine 2*60 mg/day treatment were given. He received a routine hemodialysis program for about three months. The hemodialysis program was terminated when the patient’s urine quality and quantity increased.Conclusions: SRC, characterized by malignant hypertension, azotemia, microangiopathic hemolytic anemia, and kidney failure, is one of the most important complications of systemic sclerosis with a poor prognosis without prompt intervention. Steroid use is one of the important risk factors that precipitate SRC development. With angiotensin-converting enzyme inhibitors, survival increased after SRC, the need for dialysis decreased, and usually allowed the discontinuation of dialysis treatment within about 6-18 months. Suspicion of SRC in the presence of the above-mentioned findings in patients with a diagnosis or suspected systemic sclerosis can be considered the most important treatment step.

Objective: Supraventricular tachycardia, one of the most common conditions requiring emergency cardiac intervention in newborns, is also the most common symptomatic tachyarrhythmia in newborns. Therefore, early diagnosis and treatment approach is important.
Method: Demographic findings, clinical findings, and treatment approaches of newborns hospitalized with the diagnosis of supraventricular tachycardia between January 2011 and November 2020 in the Neonatal Intensive Care Unit of our hospital were evaluated retrospectively.
Results: Thirty-eight patients without congenital heart disease (except secundum-type atrial septal defect) and diagnosed with supraventricular tachycardia were evaluated retrospectively. The mean week of gestation was 38.2 ± 1.8, the mean age at diagnosis was 10.7 ± 10.1 days, the number of patients with heart failure was 8 (21%), the number of patients with Wolff-Parkinson White syndrome was 8 (21%), the number of patients with fetal arrhythmia was 6 (15.7%) and the mean number of hospitalization days was 15.7±13.5. The patients were given adenosine in the first stage and propranolol, amiodarone, propafenone and flecainide in the second stage as medical treatment. Cardioversion was performed in 5 (13%) patients due to resistant supraventricular tachycardia.
Conclusion: Early diagnosis and treatment of supraventricular tachycardia are very important in terms of reducing morbidity and mortality. Therefore, we think that increasing awareness of supraventricular tachycardia among clinicians following newborn babies will enable newborns with supraventricular tachycardia to receive early diagnosis and treatment.
Sin og sig med flertalsantecedent fra runesten til LANCHART
Authors: Ehlers Katrine Rosendahl 
Published: September 2021

In modern Danish, the reflexive pronouns sin and sig differ in terms of their ability to corefer with a plural antecedent. The reflexive possessive sin typically only allows singular antecedents and the reflexive pronoun sig allows both singular and plural antecedents. Instead of sin, speakers use the non-reflexive deres to corefer with a plural antecedent.
This difference between sin and sig is fairly new. Up until the beginning of the twentieth century, many speakers used not only sin but also sig primarily with singular antecedents and the non-reflexive counterparts deres and dem with plural antecedents. This usage pattern goes back to before the thirteenth century. In this paper I investigate the development in the use of sin and sig with plural antecedents. In the earliest runic sources of Danish from before 1000 AD, both sin and sig are
used with plural antecedents. In the Middle Danish provincial laws from the thirteenth century, sin and sig are both restricted to occurring mainly with singular antecedents. This usage, reflexive pronouns/possessives with singular antecedents and non-reflexive pronouns/possessives with plural antecedents, is found in the spoken language at least until the twentieth century. However, I show with data from the spoken corpus LANCHART that the use of dem with plural antecedents has almost disappeared in modern Danish.
Markering af propriumsfunktion ved omvendt ledstilling
Authors: Sandst Line 
Published: September 2021

In this article, I discuss a type of proper name that is rarely discussed among linguistics and name researchers, however often found among the category of commercial names in the linguistic landscapes in cities. The proper name type differs from other proper name types due to its in Danish unconventional structure of having the part of the compound that describes the locality as the first part of the expression, e.g. Café Sommersko, and not as the last part of the compound, e.g. *Sommerskocaféen that is the common structure in Danish and other Germanic languages.
I argue that the unconventional word formation evokes the instant notion of proper name status, hence has the ability to bypass the time factor that expressions needs in order to obtain proper name status. Therefore, the unconventional expression can be used to exploit the untapped linguistic possibility in Danish language for name givers to form instant proper names.
Of Sound Mind
Authors: Kraus Nina 
Published: September 2021

How sound leaves a fundamental imprint on who we are.
Making sense of sound is one of the hardest jobs we ask our brains to do. In Of Sound Mind, Nina Kraus examines the partnership of sound and brain, showing for the first time that the processing of sound drives many of the brain's core functions. Our hearing is always on—we can't close our ears the way we close our eyes—and yet we can ignore sounds that are unimportant. We don't just hear; we engage with sounds. Kraus explores what goes on in our brains when we hear a word—or a chord, or a meow, or a screech.
Our hearing brain, Kraus tells us, is vast. It interacts with what we know, with our emotions, with how we think, with our movements, and with our other senses. Auditory neurons make calculations at one-thousandth of a second; hearing is the speediest of our senses. Sound plays an unrecognized role in both healthy and hurting brains. Kraus explores the power of music for healing as well as the destructive power of noise on the nervous system. She traces what happens in the brain when we speak another language, have a language disorder, experience rhythm, listen to birdsong, or suffer a concussion. Kraus shows how our engagement with sound leaves a fundamental imprint on who we are. The sounds of our lives shape our brains, for better and for worse, and help us build the sonic world we live in.
Born Knowing

Published: September 2021

An expert on the brain argues that the mind is not a blank slate and that much early behavior is biologically predisposed rather than learned.
Why do newborns show a preference for a face (or something that resembles a face) over a nonface-like object? Why do baby chicks prefer a moving object to an inanimate one? Neither baby human nor baby chick has had time to learn to like faces or movement. In Born Knowing, neuroscientist Giorgio Vallortigara argues that the mind is not a blank slate. Early behavior is biologically predisposed rather than learned, and this instinctive or innate behavior, Vallortigara says, is key to understanding the origins of knowledge.
Drawing on research carried out in his own laboratory over several decades, Vallortigara explores what the imprinting process in young chicks, paralleled by the cognitive feats of human newborns, reveals about minds at the onset of life. He explains that a preference for faces or representations of something face-like and animate objects—predispositions he calls “life detectors”—streamlines learning, allowing minds to avoid a confusing multiplicity of objects in the environment, and he considers the possibility that autism spectrum disorders might be linked to a deficit in the preference for the animate. He also demonstrates that animals do not need language to think, and that addition and subtraction can be performed without numbers. The origin of knowledge, Vallortigara argues, is the wisdom that humans and animals possess as basic brain equipment, the product of natural history rather than individual development.

Introduction: the prevalence of cervical and anal human papillomavirus (HPV) infection in women infected with human immunodeficiency virus (HIV) is high. However, little is known about the differences in the susceptibility of these infections and related lesions. The aim of this study was to describe the association between the prevalence of cervical and anal HPV infection and HPV-related lesions in HIV-positive women. Methods: this study included 88 HIV-positive women attending an outpatient clinic in a university hospital. Ectocervical, endocervical, and anal samples were collected for colpocytology and anal cytology. A polymerase chain reaction-based technique was used to detect HPV deoxyribonucleic acid in endocervical and anal swab samples. Results: the cervical and anal HPV positivity rates were 35.21% and 78.8%, respectively. The presence of HPV-related lesions on colpocytology was associated with anal HPV positivity (P = 0.027). The ratio between cervical HPV infection and cervical HPV-related lesions was 2.5. The ratio between anal HPV infection and anal HPV-related lesions was 4.3. Overall, 30% had concomitant HPV DNA in the cervix and anus. Conclusion: there are differences in the susceptibility of infections and related lesions between the cervix and anus. Despite a higher incidence of anal HPV, the progression to HPV-related lesion does not occur via the same manner in the cervix and anus. Moreover, cervical HPV-related lesions in HIV-positive women may serve as a cue for anal preventive strategies, and further investigations in these women may be useful.

Abstract

Objectives
This study aimed to investigate the relationship between working hours and lifestyle behaviors using data from a large nationally representative panel survey.

Methods
We used the Korea Health Panel Study (KHPS) data from 2011 to 2014. Weekly working hours and lifestyle risk factors were assessed by questionnaires. Comparing to the reference group, the weekly working hours were 40 h per week, odds ratios and 95% confidence intervals for smoking status, alcohol consumption status, and regular exercise status of other weekly working hours groups (&lt;40, 40, 41–52, and &gt;52) were calculated, using generalized estimating equation models considering repeated measures.

Results
Our findings clearly showed a relationship between long working hours and unhealthy lifestyles, such as cigarette smoking, alcohol consumption, physical inactivity, and insufficient sleep. Additionally, weekly working hours are positively associated with the amount of smoking and drinking, and inversely associated with sleep duration among those who worked 40 h or more per week.

Conclusion
Long working hours are associated with unhealthy lifestyles, such as cigarette smoking, alcohol consumption, physical inactivity, and insufficient sleep.

AbstractRho.do.spi.ril'lum. Gr. neut. n.rhodon, the rose; N.L. neut. n.Spirillum, a bacterial genus; N.L. neut. n.Rhodospirillum, the roseSpirillum.Proteobacteria / Alphaproteobacteria / Rhodospirillales / Rhodospirillaceae / RhodospirillumThe genusRhodospirillumhas harbored a diverse set of spiral‐shaped phototrophic bacteria, most of which have been reclassified as species of other genera, families, and even orders and phyla since the 1980s. The heterogeneity has been long known, but only the faith into sequence‐based information gave strong support for taxonomic rearrangements. Currently, the genusRhodospirillumcontains a single species, which is characterized by spiral‐shaped cells, motility by bipolar flagella, and internal membranes as vesicles. It performs anaerobic photosynthesis, which is restricted to anoxic light conditions due to the oxygen‐sensitive biosynthesis of bacteriochlorophyll and thus the phototrophic apparatus. It can grow photoheterotrophically as well as photoautotrophically. The key enzyme of autotrophic carbon dioxide fixation inRhodospirillum rubrum,ribulose bisphosphate carboxylase (RubisCO) type‐II, is well characterized and forms a homodimer that is also encoded in some related genera ofRhodospirillaceae. Chemotrophic growth may also occur under microoxic to oxic conditions in the dark and anaerobically by fermentation. The genus comprises mesophilic freshwater bacteria. Ubiquinones and rhodoquinones with 10 isoprene units and fatty acids typical of otherAlphaproteobacteriawith C18:1, C16:0, and C16:1as major components are present.DNA G + C content (mol%): 64.6–65.7, type 65.4 (genome analysis), 63.8–65.8 (Bd).Type species:Rhodospirillum (Rsp.) rubrumMolisch 1907AL(basonym:Spirillum rubrumEsmarch 1887).
