Robust RFI Excision for Pulsar Signals by a Novel Nonlinear M-type Estimator with an Application to Pulsar Timing
Authors: Shan 单昊 Hao
Published: July 2023

Radio frequency interference (RFI) mitigation for pulsar signals is a long perplexing issue in astrophysical measurements. Linear mitigation methods are often criticized for limited RFI excision range and weakness of RFI modeling. Meanwhile, thresholding methods (e.g., the SumThreshold) suffer from empirical factors. In our opinion, the main defect of the current status is the lack of a concise definition to distinguish signals from RFI with the aid of certain techniques, e.g., sparse representation. This point is the root cause of these problems and also forms our motivation. This paper aims to expand the excision range (e.g., the on-pulse and quasiperiodic RFI) and cut down some empirical factors. The main contribution is that we give a definition and derive a widely practicable nonlinear framework for RFI excision. This framework can overcome the susceptibility of the least-square criterion to RFI, and excise almost all types of RFI once and for all. A robust LnCosh criterion based nonlinear maximum likelihood-type (M-type) penalized smoothing estimator is introduced. The novelty is that this estimator is first embedded into the iterative shrinkage-thresholding algorithm (ISTA) and the fast ISTA. Nonlinearity highlights this method. Curvelet sparsity gives satisfying approximation for pulsar signals containing dispersion feature. Finally, useful signal details will be retrieved from the excision residual by a morphological component analysis. This method is applied to the time-frequency signals collected by the Nanshan 26 m Radio Telescope. The numerical experiments can persuasively prove that it has desired application prospects.
Magnetic Activity–Rotation–Age–Mass Relations in Late-pre-main-sequence Stars
Authors: Getman Konstantin V. , Feigelson Eric D. , Garmire Gordon P.
Published: July 2023

We study the four-dimensional relationships between magnetic activity, rotation, mass, and age for solar-type stars in the age range 5–25 Myr. This is the late-pre-main-sequence (l-PMS) evolutionary phase when rapid changes in a star's interior may lead to changes in the magnetic dynamo mechanisms. We carefully derive rotational periods and spot sizes for 471 members of several l-PMS open clusters using photometric light curves from the Zwicky Transient Facility. Magnetic activity was measured in our previous Chandra-based study, and additional rotational data were obtained from other work. Several results emerge. Mass-dependent evolution of rotation through the l-PMS phase agrees with astrophysical models of stellar angular momentum changes, although the data suggest a subpopulation of stars with slower initial rotations than commonly assumed. There is a hint of the onset of unsaturated tachoclinal dependency of X-ray activity on rotation, as reported by Argiroffi et al., but this result is not confidently confirmed. Both X-ray luminosity and starspot area decrease approximately as t
−1 for solar-mass stars, suggesting that spot magnetic fields are roughly constant and l-PMS stars follow the universal solar-scaling law between the X-ray luminosity and surface magnetic flux. Assuming convective dynamos are dominant, theoretical magnetic fluxes fail to reveal the universal law for l-PMS stars that enter late Henyey tracks. Altogether we emerge with a few lines of evidence suggesting that the transition from the turbulent to solar-type dynamo occurs at the later stages of l-PMS evolution as stars approach the zero-age main sequence.
The Distribution of Metallicities in the Local Galactic Interstellar Medium*

Published: July 2023

In this investigation, we present an analysis of the metallicity distribution that pertains to neutral gas in the local Galactic interstellar medium (ISM). We derive relative ISM metallicities for a sample of 84 sight lines probing diffuse atomic and molecular gas within 4 kpc of the Sun. Our analysis is based in large part on column density measurements reported in the literature for 22 different elements that are commonly studied in interstellar clouds. We supplement the literature data with new column density determinations for certain key elements and several individual sight lines important to our analysis. Our methodology involves comparing the relative gas-phase abundances of many different elements for a given sight line to simultaneously determine the strength of dust depletion in that direction and the overall metallicity offset. We find that many sight lines probe multiple distinct gas regions with different depletion properties, which complicates the metallicity analysis. Nevertheless, our results provide clear evidence that the dispersion in the metallicities of neutral interstellar clouds in the solar neighborhood is small (∼0.10 dex) and only slightly larger than the typical measurement uncertainties. We find no evidence for the existence of very low metallicity gas (as has recently been reported by De Cia et al.) along any of the 84 sight lines in our sample. Our results are consistent with a local Galactic ISM that is well mixed and chemically homogeneous.
Rapid Variability of the Accretion Disk Wind in the Narrow-line Seyfert 1, PG 1448+273

Published: July 2023

PG 1448+273 is a luminous, nearby (z = 0.0645), narrow-line Seyfert 1 galaxy, which likely accretes close to the Eddington limit. XMM-Newton observations of PG 1448+273 in 2017 revealed the presence of an ultrafast outflow, as seen through its blueshifted iron K absorption profile, with an outflow velocity of about 0.1 c. Here, the first NuSTAR observation of PG 1448+273, performed in 2022 and coordinated with XMM-Newton, is presented, which shows remarkable variability of its ultrafast outflow. The average count rate is a factor of 2 lower during the last 60 ks of the NuSTAR observation, where a much faster component of the ultrafast outflow was detected with a terminal velocity of 0.26 ± 0.04 c. This is significantly faster than the outflow component that was initially detected in 2017, when overall PG 1448+273 was observed at a lower X-ray flux, and which implies an order of magnitude increase in the wind kinetic power between the 2017 and 2022 epochs. Furthermore, the rapid variability of the ultrafast outflow in 2022, on timescales down to 10 ks, suggests we are viewing through a highly inhomogeneous disk wind in PG 1448+273, where the passage of a denser wind clump could account for the increase in obscuration in the last 60 ks of the NuSTAR observation.
Comparing Complex Chemistry in Neighboring Hot Cores: NOEMA Studies of W3(H2O) and W3(OH)

Published: July 2023

Presented here are NOEMA interferometric observations of the neighboring hot cores W3(H2O) and W3(OH). The presence of two star-forming cores at different evolutionary stages within the same parent cloud presents a unique opportunity to study how the physics of the source and its evolutionary stage impact the chemistry. Through spectral analysis and imaging, we identify over 20 molecules in these cores. Most notably, we have detected HDO and CH3CH2CN in W3(OH), which were previously not detected in this core. We have imaged the molecular emission, revealing new structural features within these sources. W3(OH) shows absorption in a “dusty cocoon” surrounded by molecular emission. These observations also reveal extended emission that is potentially indicative of a low-velocity shock. From the information obtained herein, we have constructed column density and temperature maps for methanol and compared this information to the molecular images. By comparing the spatial distribution of molecules that may be destroyed at later stages of star formation, this work demonstrates the impact of physical environment on chemistry in star-forming regions at different evolutionary stages.
Pulsation-induced Spectroscopic Variability of IRAS Z02229+6208
Authors: Začs Laimons , Puķı̄tis Kārlis
Published: July 2023

Monitoring of high-resolution spectra in the optical and near-infrared wavelength region was carried out for the early post-AGB stage star IRAS Z02229+6208 with the CARMENES instrument to reveal spectroscopic variability over the pulsation cycle of 154 days. Significant changes are seen in both the intensity and position of carbon-bearing molecular lines. Strong and broad CN red system lines, blueshifted up to 9.4 km s−1 relative to the stellar photosphere, are seen near the light minimum. Near the light maxima, the molecular features are weak and most of them are in emission, e.g., broad emissions in the CN red system (0,0) lines are seen. A site of formation of molecular absorptions and emissions appears to be an extended atmosphere of a cool post-AGB star affected by stellar pulsation. In addition, we observed narrow absorption lines of the C2 Phillips (2, 0), (3, 0) system and the CN red system (2,0), most likely related to the circumstellar envelope produced during the evolution on the asymptotic giant branch (AGB). An expansion velocity of the circumstellar shell was found to be V
exp = −11.1 km s−1 relative to the stellar mass center, in agreement with that estimated before from CO lines. The observed spectroscopic variability seems to be typical for pulsating early post-AGB stage stars.
WHEELS AND VICARIOUS CIRCLES: The Making of Apparatus of Repair

Published: July 2023

In 2021 and 2022, I led the creation of a site specific performance project rooted in my belief that alternatives to incarceration create more public safety than prisons and punishment-driven caging. “Apparatus of Repair” is the third in a trilogy of public art projects called The Decarceration Trilogy: Dismantling the Prison Industrial Complex one Dance at a Time. It gathered currently and formerly incarcerated people, as well as survivors of violence. Over two years we dove into restoration, via a vicarious restorative process, knowing that the conversations we generated would inform the creation of site specific public art. This article reflects on the process and performances.
 
En 2021 et 2022, j’ai piloté la création d’un projet de performance in situ avec la conviction personnelle que les alternatives à l’incarcération sont plus bénéfiques en termes de sécurité publique que les prisons et autres formes d’enfermement punitif. « Apparatus of Repair » ( « Réparer à ciel ouvert ») est le troisième volet d’une trilogie de projets artistiques publics baptisée The Decarceration Trilogy: Dismantling the Prison Industrial Complex one Dance at a Time (Trilogie de la non-incarcération : démantèlement du complexe carcéral industriel, pas à pas). Ce projet rassemble des personnes incarcérées et des ex-détenu·e·s, ainsi que des survivant·e·s de violences. Pendant plus de deux ans, nous nous sommes immergé·e·s dans la réparation à l’aide de processus indirects, sachant que les conversations engendrées façonneraient la création d’un art public insitu.

Paving the way to Struggle
Authors: Ningtyas Eka
Published: July 2023

Kebatinan (“the knowledge of spirit”) is a religious movement first established in 1955 with the Semarang theosophical group’s support. The movement’s name is derived from mystical practices that have developed in the Malay world since the end of the 19th century, characterized by an emphasis on spirituality to get closer to God. This article focuses on the formation of religious discourse in the Indonesian Kebatinan Congress of 1955 as a response to the relationship between the state and society within the framework of religion as codified by the Pancasila. The main concerns of this paper are the formation of the concept of kebatinan, the debates it raised, and the position of the Kebatinan movement within the religious discourse in 1950s Indonesia. The article argues that at this period, Indonesia’s religious discourse was fluid and loosely formalized. The progressive formalization process starting from this period can be analyzed through the formation of an umbrella organization for the Kebatinan movement by some adherents who considered themselves as representing a brand different from mainstream religious institutions.
On the Road of Hijrah: Contesting Identity through Urban Mobilities in Contemporary Indonesian Muslims
Authors: Fansuri Hamzah
Published: July 2023

This article analyses how the hijrah movement, a contemporary religious movement that reinterprets the meaning and practices of being pious, has gained widespread sympathy among Indonesian urban Muslims. Although numerous studies have endeavoured to scrutinize the phenomenon of hijrah in communities or movements, most focus on social media, and only a few examine their daily mobilities in urban life. By focusing on the Kajian Musawarah, one of Indonesia’s most prominent hijrah communities and employing interdependent mobilities, the article reveals those activists and followers of such community contest new Islamic identities through their intersections with various forms of urban mobilities. Within physical, imaginative, virtual, and communicative travel, the Kajian Musawarah amplifies the symbolic value of hijrah over Islamic attributes, including clothing, language and recitation circles to attract urban Muslims. Furthermore, their Islamic identity is also contesting many aspects of social life such as urban lifestyle, consumptive culture, and relation to other Muslim and non-Muslim communities.

Published: July 2023

The U.S. Army Aviation Development Directorate has developed generic high-fidelity flight-dynamics models of two advanced high-speed rotorcraft configurations - a lift offset coaxial helicopter with a pusher propeller and a tiltrotor. The models were developed to provide the government with independent control-system design, handling-qualities analysis, and simulation research capabilities for these types of aircraft in support of the Future Vertical Lift initiate. Full flight envelope explicit model following control systems were designed for both configurations using a multi-objective optimization approach to meet a comprehensive set of stability, handling qualities, and performance requirements. The control laws for both aircraft were evaluated in a piloted simulation experiment at the NASA Ames Vertical Motion Simulator using a series of high-speed handling qualities demonstration maneuvers. This paper discusses the control laws and the results of the piloted handling qualities assessment. The results from the simulation experiment show overall assigned Level 1 handling qualities for both aircraft.

Authors: Rivera Oscar
Published: July 2023

El lugar donde vivimos como integrantes de una colectividad tiene una influencia sustancial en la toma de decisiones y en la definición de una identidad. Todos los elementos que determinan un contexto de convivencia social implican los elementos objetivos con los que los individuos definimos nuestro actuar. EL objetivo de este artículo es evidenciar cómo un contexto de violencia puede influir en un proceso de normalización hacia las conductas de violencia intrafamiliar y violencia hacia las mujeres. Se llevó a cabo un estudio exploratorio de corte cualitativo en las colonias de mayor incidencia delictiva en el municipio de Mexicali, Baja California enfocado a jóvenes entre 14-19 años. Se encuestaron a 629 jóvenes durante el año 2021 y se obtuvieron las estadísticas de incidencia delictiva de siete colonias consideradas como de alta prioridad por el municipio. Los resultados arrojan que existe un proceso de normalización hacia conductas violentas por parte de aquellos jóvenes que conviven en espacios donde la violencia familiar y de género tienen una presencia cotidiana. Resulta trascendente una aproximación descriptiva con estas dimensiones debido a que la identidad de los jóvenes está permanentemente en construcción y define quiénes son y cómo se ven a sí mismos en relación con el mundo que los rodea.

Machine-based algorithm: a revolution we need for early sepsis diagnosis in hospitals
Authors: Shahid Muhammad Usama , Furqan Madiha , Fatima Syeda Zainab
Published: July 2023

Dear Editor,
Sepsis is a life-threatening medical emergency and one of the fundamental causes of early mortality within hospitals. WHO report of 2020 shows that nearly 11 million people worldwide die from sepsis yearly (1). It commonly affects neonates and children; however, pregnant women, the elderly, cancer patients, and bed-bound individuals are particularly at high risk of developing sepsis as well due to the immunosuppressant state of their condition. Sepsis is a clinical diagnosis; thus majorly depends upon a multitude of symptoms, clinical examinations, baseline investigations, and the expertise of the clinicians. Unfortunately, all these methods are highly non-specific, making the diagnosis difficult.
Owing to its high mortality, the key to survival lies in the timely initiation of the therapy. Therefore, sepsis requires early diagnosis to help save the life of an affected individual. In this search, multiple systems and methods have been developed previously and used in various hospitals. It includes evaluating by SIRS criteria, detecting the levels of pro-inflammatory markers in the serum, and by newer techniques like diagnosing using electrochemical sensors like PCT (procalcitonin), optical and fluorometric sensors, and microfluidic sensors. These detect different biomarkers in the serum of the patients and thus help in rapid diagnosis. Regardless, the sensitivity and specificity of these systems remain low.

Tios, perus e tucano: notas sobre um perspectivismo rosiano
Authors: Pansica Rafael
Published: July 2023

Este artigo propõe uma leitura comparativa entre dois contos de Guimarães Rosa publicados em Primeiras Estórias (1962), “As margens da alegria” e “Os cimos”. O espelhamento dessas estórias nos permitirá apontar o posicionamento político-artístico do autor que será caracterizado, aqui, como um posicionamento perspectivista. O tratamento literário da colonização do sertão brasileiro nesses contos não faz apenas a denúncia crítica da destruição do ecossistema do cerrado, mas apontará também para o ataque contra um regime social perspectivista constituído pela mútua implicação afetiva dos seres que povoam o que costumamos separar como “natureza” e “sociedade”.

Dünyada olduğu gibi ülkemizde de nüfusun büyük çoğunluğunun kent merkezlerinde yaşıyor olması kentsel alanlar üzerinde yoğun bir insan baskısına sebep olmaktadır. İnsanların yaşamsal ihtiyaçlarının (barınma, iş, eğitim, sağlık, sosyal yaşam vb.) gereği olarak ortaya çıkan bu baskılar kentsel alanlarda yapı yoğunluğunun artmasına, arazi formunun değişmesine ve iklimin değişmesine neden olmaktadır. İklimin değişmesi hem açık mekanların hem de kapalı mekanların tasarımında yeni stratejilerin geliştirilmesini gerekli kılmaktadır. Bu stratejilerle oluşturulacak planlama ve tasarım kararları ve çözümleri bugün olduğu kadar gelecekte de bu değişimlerin etkilerinin öngörüldüğü senaryolarla ilişkilendirilmelidir.

Bu bakış açısıyla “Geleceğin iklim senaryolarına hazırlıklı, sürdürülebilir, dirençli, kentsel peyzajlar oluşturmak için hangi parametreler önemlidir?”, “Başarılı uygulama örnekleri hangi yönleri ile öne çıkmaktadır?” soruları araştırmanın çıkış noktasını oluşturmaktadır. Araştırma, “Kentlerimizi geleceğin iklim senaryolarına hazırlamak için peyzaj tasarımı stratejileri neler olmalıdır?” sorusuna odaklanmaktadır. Bu kapsamda iklim değişiminin hangi parametreleri etkilediği ve etkilerin kentsel peyzaj alanlarına yansımaları kuramsal olarak literatür bilgileri ile açıklanmıştır. Bu bilgiler ışığında kentsel alanlarda yapılacak peyzaj tasarımı uygulamalarında düşünülmesi gereken tasarım stratejileri ve çözüm önerileri ortaya konulmuştur. Sonuçta teorik ve pratik çerçevede yapılan değerlendirmelerle iklim senaryolarına hazırlıklı kentsel peyzaj uygulamaları ile ilgili öneriler geliştirilmiştir.

Book review - Claiming the City: A Global History of Workers' Fight for Municipal Socialism by Shelton Stromquist. 2023
Authors: Rolf Hannes
Published: July 2023

Shelton Stromquist has written a long and very rich account of the international history of local socialist activism, often called municipal socialism. Drawing on various examples, Stromquist wants to shift the focus from national parliamentary politics and centrist narratives to the local level, where the labour movement was built. At a time when local struggles such as affordable housing are once again on the agenda of progressive activists, this book offers important insights into the early local history of labour politics and inspiration for contemporary activists and municipal socialists.

In order to study the influence of long flight time on the operation
performance of personnel under the electronic map color scheme and obtain
the electronic map color scheme suitable for long flight time, this study
designed an ergonomic experiment simulating the operation of electronic map
by personnel under the environment of 60 days of long flight time, and
studied the operation performance of four electronic map color schemes:
color matching, sunlight color matching, yellow light source color matching
and gray color matching. The results show that the long endurance has a
significant impact on the operation performance of different color schemes,
and the color scheme of yellow light source has good operation performance
and is more applicable under the condition of long endurance.
The effect of operation steps on the efficiency of human-computer
interaction

Published: July 2023

In the field of human-computer interaction design, the efficiency of
interaction operations has become an increasing concern, and how to complete
tasks quickly and accurately has become the focus of our research.
Therefore, this study took the two tasks of "information addition" and
"information deletion" as typical cases, and carried out ergonomic
experiments. By analyzing the physiological indicators and performance
indicators of operators in the process of completing tasks, the completion
of tasks under different operating steps was analyzed. The results show that
the performance of the task is significantly improved after the reduction of
interaction steps. This conclusion can be applied to the human-machine
interface interaction design to improve the efficiency of user interaction
operations.

Statistics show that the fertility rate has decreased during the last
decades, but life expectancy has more than doubled during the last century.
It indicates that there is a trend of more and more working-aged people
traveling in the cities. It becomes more problematic when we look at the
study of the United Nations which estimates that 55% of the world's
population lives in urban areas and projects a proportion of 70% by 2050.
This is a problem because most cities have not been planned to bear flows of
people of this magnitude, and this is the root cause of most mobility issues
that people face every day over the world. On the other hand, technological
evolution has been outstanding in the last few years, and smart cities can
make use of this advancement, especially to improve urban mobility. Examples
of technologies that have been adopted in this field are the Internet of
Things, Big Data, Artificial Intelligence, Intelligent Information Systems,
and Intelligent Transportation Systems. This work aims to highlight the
importance of all these tools in the application scenario of smart cities
and, with this aim, brings an overview of each of them and a bibliographic
review that shows how they are being currently discussed and adopted.

We developed a simulator to practice the digital disimpaction technique,
a kind of excretory care that is commonly performed by home-care nurses in
Japan. The key point of this study is that the requirements for creating a
simulation model were not known in advance, so we adopted a rapid
prototyping method, in which product development is carried out by
repeatedly creating and testing simple prototypes and a user-participatory
design method, where feedback is obtained directly from users. We proceeded
with the development of the simulator and the definition of requirements
simultaneously, repeating the process of creation, trial use, and feedback
from interviews with skilled nurses. Digital disimpaction is a complex
procedure involving interaction with a living body, in which a finger
stimulates the rectum and facilitates the excretion of feces leveraging the
rectum's natural biological response. Digital disimpaction is performed
primarily by a nurse. Since digital disimpaction is an embarrassing and
sometimes painful procedure for the patient, a smooth and comfortable
technique is desirable. On the other hand, only a limited set of
circumstances are provided to learn the digital disimpaction technique. The
requirement for a "procedure requiring non-visible interaction," such as
digital disimpaction, is hard to acquire through a simple interview because
it is performed based on subjective sensation. Further, while the movement
of the finger within the body is crucial, it is essentially impossible to
learn through observation of a skilled nurse as it is not visible from the
outside. For this reason, we created a simple rectal model as a first
prototype. We improved the model by extracting requirements from
observations and feedback on actual trial use by skilled nurses. From the
first user experience of the simple 3D printed model, requirements were
extracted regarding the texture of the rectum, the interaction between
finger movement and rectal response, and the characteristics of the feces. A
rectal model with a mucosal structure and a fecal model was created based on
the obtained requirements. Through the second user experience, the process
was repeated, where requirements were again extracted regarding the shape of
the rectal model, the characteristics of the mucosa, and the rectal response
with the finger movement. We redesigned the model to meet these refined
requirements and developed a buttock model covering the rectal model.The
results of the third user experience confirmed that the simulator mostly
reproduced the intestinal setting as perceived by the nurses during the
actual digital disimpaction procedure. This study suggests that the
combination of rapid prototyping and user-participatory design can be used
to systemize subjects for which requirements are hard to define in advance,
such as care procedures based on tacit knowledge.

The need of nursing staff will continue to increase in the next years.
At the same time, the healthcare system will face an increase of elderly
people. So, the future society will be confronted with socio-political and
economic challenges. It is expected that human-robot collaboration will
increase in healthcare. This should support and relieve care staff. An
online study was conducted to examine differences in the acceptance of
different care robots and the general attitude towards robots in the
healthcare sector. To additionally analyze the impact of the COVID-19
pandemic, two different measurement times were used, one at the beginning of
the pandemic resp. after the first corona wave and the first lockdowns, and
one five months later. The results of the study should help to understand
the acceptance of the potential use of different robots in healthcare and
the impact of the COVID-19 pandemic.
