Authors: Gunawan Elizabeth , Calista Helena , Frite Patricia , Isfandriani Rerry , Suwanto Kartika Magdalena
Published: July 2022

Makalah ini merupakan penjelasan lengkap tentang proses desain identitas visual es krim Verenice yang diproduksi oleh mahasiswa program studi Teknik Pangan Universitas Pelita Harapan. Verenice adalah es krim rendah lemak yang menggunakan susu almond sebagai bahan dasarnya, serta memiliki warna biru yang khas dan alami dari ekstrak bunga telang. Susu almond tersebut membuat es krim ini rendah lemak dibandingkan menggunakan susu full cream, sedangkan bunga telang memiliki nutrisi tinggi dan kaya akan antioksidan yang sangat berkhasiat untuk kulit manusia. Dalam mendesain identitas visual untuk produk inovatif ini, terdapat beberapa tahapan yang dibagi dalam tiga kategori, yakni pra-desain, desain, dan pasca-desain. Penulis melakukan eksplorasi identitas visual dengan menggunakan morphological matrix. Selanjutnya, penulis melakukan evaluasi dari ketiga hasil alternatif desain identitas visual yang kemudian akan diaplikasikan dalam desain kemasan. Setiap alternatif desain memiliki eksplorasi yang berbeda-beda agar mendapatkan satu desain yang akan difinalisasikan. Dengan makalah ini, penulis berharap dapat membentuk identitas visual desain yang terintegrasi.

Penggunaan desain minimalis semakin marak digunakan pada era modern ini. Tren desain yang telah berkembang ini mengakibatkan sejumlah perusahaan seperti Google dan Microsoft, untuk memperbarui desain logo mereka disesuaikan dengan zaman namun justru menerima banyak kritik. Sebagai seorang desainer, mengikuti tren tentu adalah hal yang dapat meningkatkan peluang kerja dan mengembangkan kemampuan agar tetap mengikuti zaman. Namun, semakin banyaknya perusahaan dengan gaya logo yang sama, menghilangkan keunikan dan rasa “akrab” kita dengan logo orisinal mereka. Tujuan dari makalah ini adalah untuk mengetahui alasan rebranding logo ikon Google Workspace dan logo Microsoft Edge. Juga untuk membandingkan kritik para pengguna mengenai desain minimalis hasil rebranding logo ikon Google Workspace dan logo Microsoft Edge pada citra perusahaan Google dan Microsoft.

Reformas en el régimen local general: el inicio de un nuevo ciclo
Authors: Velasco Francisco
Published: July 2022

De forma discreta, y oculto por el protagonismo de la Covid-19 durante los dos últimos años, se ha iniciado, con intensidad muy diversa según las materias, un proceso de reforma del régimen local básico: para los municipios pequeños, para la ciudad de Barcelona y respecto de la financiación local. En este proceso de reformas normativas tiene que estar muy presente la diversidad local y territorial de España. Esta diversidad no impide la regulación básica estatal, ni siquiera para concretos grupos de municipios o para concretas ciudades, pero sí aconseja que esa regulación sea flexible y, en algunas materias, desplazable en su eficacia por las leyes autonómicas o las ordenanzas y reglamentos locales. La misma idea de diversidad debe estar presente en el sistema de financiación, que ha de entroncar con la financiación autonómica y debe conectar más intensamente cada fuente de financiación (mediante tributos propios o por transferencias) con cada tipo de municipios

Authors: Gurpreet Singh  , DK Sharma  , Deepali Pathak  , Sumanta Dutta
Published: July 2022

Background: Time since death (TSD) is the period between the death and time of examination of a body. Numerousstudies conducted on analysis of potassium in vitreous humour have shown that the vitreous potassium levelsincrease with rise in TSD. Studies done on postmortem biochemistry of synovial fluid have proposed a positivelinear relationship between potassium and TSD. But, very few authors have compared findings of these two fluids.So, this study was undertaken to compare the accuracy of determining post-mortem interval from Sodium andPotassium levels of vitreous humour and synovial fluid.Methods: A total of 140 cases were taken with certified time of death. These were divided into 7 groups i.e.0-6 hours, 6-12 hours, 12-18 hours, 18-24 hours, 24-30 hours, 30-36 hours and above 36 hours. Vitreous humour andSynovial fluid from knee joint were aspirated from both sides of body and were analyzed using Medica EasylyteNa/K Analyser. Results were obtained using SPSS 24 software.Conclusions: Potassium has a strong positive correlation with TSD in both fluids. Sodium has weak negativecorrelation. There is no difference between values of both sides. There is no statistically significant differencebetween values of Vitreous humour and Synovial Fluid. Hence, both can be used alternatively.

Published: July 2022

This review article shows the history of the development of Japanese national garden culture from ancient times to the Meiji Revolution. This is a time span of more than 2,300 years. The development of Japanese horticulture is considered from the point of view of its inextricable connection with political events within the country and the accompanying economic situation. The Japanese garden, as a historical and cultural phenomenon and one of the most popular trends in landscape art, has been stirring the minds of researchers in various fields of knowledge on all continents for more than 150 years. Gardens only at first glance were intended for pleasure and pleasant pastime, at the same time they carried the deepest philosophical meaning, forced the mind to work, deciphering the ancient treatises of the sages, trained the imagination. The data on the formation and development of horticultural techniques in each of the historical periods of Japan are given.

Published: July 2022

The review provides an analysis of the development of Japanese ornamental gardening from the Meiji period to the present. In historical terms, this short period of time of about 155 years originates in the restoration of the imperial power of Japan after the last shogun resigned his authority to govern the country. It is characterized by high rates of industrialization of the economy, which could not but affect the development of many traditional arts, including gardening. It was during this period that Japanese traditions were imported to the countries of the Old and New World, Japanese gardens were built outside the country. At the same time, European art, technology and traditions are penetrating Japan and have a strong influence on the culture of the country. The influence of Western art led to the emergence of eclectic gardens, but brought a certain fresh stream to modern decorative gardening. The complex, but always recognizable structure and appearance of the Japanese garden are gradually giving way to simplified forms of European-American design, while outside Japan interest in Japanese gardens is not decreasing and more and more Japanese architects are building traditional Japanese gardens in other countries.

In the cultural history of China for many millennia, plants have played a significant role in fine and applied arts, landscape architecture, cooking and healing. At the dawn of civilization, plants were used by people to survive in difficult conditions, mainly for food and medical purposes. With the spiritual development of society, the emergence of philosophical and religious teachings, the expansion of botanical knowledge, they became increasingly integrated into the daily life of ethnic groups, becoming objects of worship and hoped for symbolism and imagery. Often the same plants of local flora can be found in gardens, in pharmacopoeias, and in culinary recipes. Considering the most popular plants of Chinese gardens, the authors analyze the general patterns of the use of local plants in the cultural field of various regions of China and their impact on certain branches of knowledge in other countries. The example given in the article of the spread of folk herbal medicine from one country around the world makes it possible to assess the processes of globalization taking place in the field of culture.
THE MOTIVATIONS OF CHINESE INDIVIDUAL FOREIGN INVESTORS IN THE AUSTRALIAN RESIDENTIAL REAL ESTATE MARKET
Authors: Wu Po-Jui , Chen Athena Ying
Published: July 2022

There is an increasing number of Chinese individual foreign investors (IFIs) in Australian residential real estate markets, but few studies specifically focus on Chinese IFIs and comprehensively analyse these investors’ motivations in the Australian real estate market. This paper examines the motivations of IFIs in the Australian residential real estate markets. A qualitative historical research approach was employed to examine the topic. By using semi-structured interviews of Chinese individual investors (consisting of Chinese temporary residents and Chinese nonresidents) and Australian agents in Australian residential real estate from 2014 to 2015, the paper finds four common motivations (good living environment, stable political environment, cost efficiency and profit returns) and three distinct motivations (education, immigration and bandwagon effects) of Chinese IFIs. It was found that cost efficiency, profit returns, education investment and immigration tend to be articulated differently between Chinese temporary residents and Chinese nonresidents, although these four motivations were expressed by both. Chinese nonresidents consider cost efficiency and profit returns as their major motivations. In contrast to Chinese nonresidents, education, and immigration are the most important motivations instead of some traditional motivations such as profit returns or cost efficiency for Chinese temporary residents.

We present the current state of models for the z ∼ 3 carbon monoxide (CO) line intensity signal targeted by the CO Mapping Array Project (COMAP) Pathfinder in the context of its early science results. Our fiducial model, relating dark matter halo properties to CO luminosities, informs parameter priors with empirical models of the galaxy–halo connection and previous CO (1–0) observations. The Pathfinder early science data spanning wavenumbers k = 0.051–0.62 Mpc−1 represent the first direct 3D constraint on the clustering component of the CO (1–0) power spectrum. Our 95% upper limit on the redshift-space clustering amplitude A
clust ≲ 70 μK2 greatly improves on the indirect upper limit of 420 μK2 reported from the CO Power Spectrum Survey (COPSS) measurement at k ∼ 1 Mpc−1. The COMAP limit excludes a subset of models from previous literature and constrains interpretation of the COPSS results, demonstrating the complementary nature of COMAP and interferometric CO surveys. Using line bias expectations from our priors, we also constrain the squared mean line intensity–bias product,

⊙ Mpc−3 (95% upper limits). Based on early instrument performance and our current CO signal estimates, we forecast that the 5 yr Pathfinder campaign will detect the CO power spectrum with overall signal-to-noise ratio of 9–17. Between then and now, we also expect to detect the CO–galaxy cross-spectrum using overlapping galaxy survey data, enabling enhanced inferences of cosmic star formation and galaxy evolution history.

We introduce COMAP-EoR, the next generation of the Carbon Monoxide Mapping Array Project aimed at extending CO intensity mapping to the Epoch of Reionization. COMAP-EoR supplements the existing 30 GHz COMAP Pathfinder with two additional 30 GHz instruments and a new 16 GHz receiver. This combination of frequencies will be able to simultaneously map CO(1–0) and CO(2–1) at reionization redshifts (z ∼ 5–8) in addition to providing a significant boost to the z ∼ 3 sensitivity of the Pathfinder. We examine a set of existing models of the EoR CO signal, and find power spectra spanning several orders of magnitude, highlighting our extreme ignorance about this period of cosmic history and the value of the COMAP-EoR measurement. We carry out the most detailed forecast to date of an intensity mapping cross correlation, and find that five out of the six models we consider yield signal to noise ratios (S/Ns) ≳ 20 for COMAP-EoR, with the brightest reaching a S/N above 400. We show that, for these models, COMAP-EoR can make a detailed measurement of the cosmic molecular gas history from z ∼ 2–8, as well as probe the population of faint, star-forming galaxies predicted by these models to be undetectable by traditional surveys. We show that, for the single model that does not predict numerous faint emitters, a COMAP-EoR-type measurement is required to rule out their existence. We briefly explore prospects for a third-generation Expanded Reionization Array (COMAP-ERA) capable of detecting the faintest models and characterizing the brightest signals in extreme detail.

We describe the first-season CO Mapping Array Project (COMAP) analysis pipeline that converts raw detector readouts to calibrated sky maps. This pipeline implements four main steps: gain calibration, filtering, data selection, and mapmaking. Absolute gain calibration relies on a combination of instrumental and astrophysical sources, while relative gain calibration exploits real-time total-power variations. High-efficiency filtering is achieved through spectroscopic common-mode rejection within and across receivers, resulting in nearly uncorrelated white noise within single-frequency channels. Consequently, near-optimal but biased maps are produced by binning the filtered time stream into pixelized maps; the corresponding signal bias transfer function is estimated through simulations. Data selection is performed automatically through a series of goodness-of-fit statistics, including χ
2 and multiscale correlation tests. Applying this pipeline to the first-season COMAP data, we produce a data set with very low levels of correlated noise. We find that one of our two scanning strategies (the Lissajous type) is sensitive to residual instrumental systematics. As a result, we no longer use this type of scan and exclude data taken this way from our Season 1 power spectrum estimates. We perform a careful analysis of our data processing and observing efficiencies and take account of planned improvements to estimate our future performance. Power spectrum results derived from the first-season COMAP maps are presented and discussed in companion papers.
Effects of CO-dark Gas on Measurements of Molecular Cloud Stability and the Size–Linewidth Relationship
Authors: O’Neill Theo J. , Indebetouw Rémy , Bolatto Alberto D. , Madden Suzanne C. , Wong Tony
Published: July 2022

Stars form within molecular clouds, so characterizing the physical states of molecular clouds is key to understanding the process of star formation. Cloud structure and stability are frequently assessed using metrics including the virial parameter and Larson scaling relationships between cloud radius, velocity dispersion, and surface density. Departures from the typical Galactic relationships between these quantities have been observed in low-metallicity environments. The amount of H2 gas in cloud envelopes without corresponding CO emission is expected to be high under these conditions; therefore, this CO-dark gas could plausibly be responsible for the observed variations in cloud properties. We derive simple corrections that can be applied to empirical clump properties (mass, radius, velocity dispersion, surface density, and virial parameter) to account for CO-dark gas in clumps following power-law and Plummer mass density profiles. We find that CO-dark gas is not likely to be the cause of departures from Larson’s relationships in low-metallicity regions, but that virial parameters may be systematically overestimated. We demonstrate that correcting for CO-dark gas is critical for accurately comparing the dynamical state and evolution of molecular clouds across diverse environments.

We present Atacama Large Millimeter Array band 6/7 (1.3 mm/0.87 mm) and Very Large Array Ka-band (9 mm) observations toward NGC 2071 IR, an intermediate-mass star-forming region. We characterize the continuum and associated molecular line emission toward the most luminous protostars, i.e., IRS1 and IRS3, on ∼100 au (0.″2) scales. IRS1 is partly resolved in the millimeter and centimeter continuum, which shows a potential disk. IRS3 has a well-resolved disk appearance in the millimeter continuum and is further resolved into a close binary system separated by ∼40 au at 9 mm. Both sources exhibit clear velocity gradients across their disk major axes in multiple spectral lines including C18O, H2CO, SO, SO2, and complex organic molecules like CH3OH, 13CH3OH, and CH3OCHO. We use an analytic method to fit the Keplerian rotation of the disks and give constraints on physical parameters with a Markov Chain Monte Carlo routine. The IRS3 binary system is estimated to have a total mass of 1.4–1.5 M
⊙. IRS1 has a central mass of 3–5 M
⊙ based on both kinematic modeling and its spectral energy distribution, assuming that it is dominated by a single protostar. For both IRS1 and IRS3, the inferred ejection directions from different tracers, including radio jet, water maser, molecular outflow, and H2 emission, are not always consistent, and for IRS1 these can be misaligned by ∼50°. IRS3 is better explained by a single precessing jet. A similar mechanism may be present in IRS1 as well but an unresolved multiple system in IRS1 is also possible.
Using LSST Microlensing to Constrain Dark Compact Objects in Spherical and Disk Configurations
Authors: Winch Harrison , Setford Jack , Bovy Jo , Curtin David
Published: July 2022

The Legacy Survey of Space and Time (LSST) with the Vera Rubin Observatory will provide strong microlensing constraints on dark compact objects (DCOs) in our Galaxy. However, most current forecasts limit their analysis to Primordial Black Holes (PBH). It is unclear how well LSST microlensing will be able to constrain alternative models of DCOs with different Galactic spatial profile distributions at a subdominant DM fraction. In this work, we investigate how well LSST microlensing will constrain spherical or disk-like Galactic spatial distributions of DCOs, taking into account extended observing times, baryonic microlensing background, and sky distribution of LSST sources. These extensions represent significant improvements over existing microlensing forecasts in terms of both accuracy and versatility. We demonstrate this power by deriving new LSST sensitivity projections for DCOs in spherical and disk-like distributions. We forecast that LSST will be able to constrain one-solar-mass PBHs to have a DM fraction under 4.1 × 10−4. One-solar-mass objects in a dark disk distribution with the same dimensions as the Galactic disk will be constrained below 3.1 × 10−4, while those with m = 105
M
⊙ will be constrained to below 3.4 × 10−5. We find that compressed dark disks can be constrained up to a factor of ∼10 better than ones with identical dimensions to the baryonic disk. We also find that dark disks become less tightly constrained when they are tilted with respect to our own disk. This forecasting software is a versatile tool, capable of constraining any model of DCOs in the Milky Way with microlensing, and is made publicly available.
A Late-time Radio Flare Following a Possible Transition in Accretion State in the Tidal Disruption Event AT 2019azh

Published: July 2022

We report here radio follow-up observations of the optical tidal disruption event (TDE) AT 2019azh. Previously reported X-ray observations of this TDE showed variability at early times and a dramatic increase in luminosity, by a factor of ∼10, about 8 months after optical discovery. The X-ray emission is mainly dominated by intermediate hard-soft X-rays and is exceptionally soft around the X-ray peak, which is L

X
∼ 1043 erg s−1. The high cadence 15.5 GHz observations reported here show an early rise in radio emission followed by an approximately constant light curve, and a late-time flare. This flare starts roughly at the time of the observed X-ray peak luminosity and reaches its peak about 110 days after the peak in the X-ray, and a year after optical discovery. The radio flare peaks at ν
L

ν
∼ 1038 erg s−1, a factor of two higher than the emission preceding the flare. In light of the late-time radio and X-ray flares, and the X-ray spectral evolution, we speculate a possible transition in the accretion state of this TDE, similar to the observed behavior in black hole X-ray binaries. We compare the radio properties of AT 2019azh to other known TDEs, and focus on the similarities to the late-time radio flare of the TDE ASASSN-15oi.
Magnetar Bursts Due to Alfvén Wave Nonlinear Breakout
Authors: Yuan Yajie , Beloborodov Andrei M. , Chen Alexander Y. , Levin Yuri , Most Elias R. , Philippov Alexander A.
Published: July 2022

The most common form of magnetar activity is short X-ray bursts, with durations from milliseconds to seconds, and luminosities ranging from 1036–1043 erg s−1. Recently, an X-ray burst from the galactic magnetar SGR 1935+2154 was detected to be coincident with two fast radio burst (FRB) like events from the same source, providing evidence that FRBs may be linked to magnetar bursts. Using fully 3D force-free electrodynamics simulations, we show that such magnetar bursts may be produced by Alfvén waves launched from localized magnetar quakes: a wave packet propagates to the outer magnetosphere, becomes nonlinear, and escapes the magnetosphere, forming an ultra-relativistic ejecta. The ejecta pushes open the magnetospheric field lines, creating current sheets behind it. Magnetic reconnection can happen at these current sheets, leading to plasma energization and X-ray emission. The angular size of the ejecta can be compact, ≲1 sr if the quake launching region is small, ≲0.01 sr at the stellar surface. We discuss implications for the FRBs and the coincident X-ray burst from SGR 1935+2154.

Type Ia supernovae (SNe Ia) are more precise standardizable candles when measured in the near-infrared (NIR) than in the optical. With this motivation, from 2012 to 2017 we embarked on the RAISIN program with the Hubble Space Telescope (HST) to obtain rest-frame NIR light curves for a cosmologically distant sample of 37 SNe Ia (0.2 ≲ z ≲ 0.6) discovered by Pan-STARRS and the Dark Energy Survey. By comparing higher-z HST data with 42 SNe Ia at z < 0.1 observed in the NIR by the Carnegie Supernova Project, we construct a Hubble diagram from NIR observations (with only time of maximum light and some selection cuts from optical photometry) to pursue a unique avenue to constrain the dark energy equation-of-state parameter, w. We analyze the dependence of the full set of Hubble residuals on the SN Ia host galaxy mass and find Hubble residual steps of size ∼0.06-0.1 mag with 1.5σ−2.5σ significance depending on the method and step location used. Combining our NIR sample with cosmic microwave background constraints, we find 1 + w = −0.17 ± 0.12 (statistical + systematic errors). The largest systematic errors are the redshift-dependent SN selection biases and the properties of the NIR mass step. We also use these data to measure H
0 = 75.9 ± 2.2 km s−1 Mpc−1 from stars with geometric distance calibration in the hosts of eight SNe Ia observed in the NIR versus H
0 = 71.2 ± 3.8 km s−1 Mpc−1 using an inverse distance ladder approach tied to Planck. Using optical data, we find 1 + w = −0.10 ± 0.09, and with optical and NIR data combined, we find 1 + w = −0.06 ± 0.07; these shifts of up to ∼0.11 in w could point to inconsistency in the optical versus NIR SN models. There will be many opportunities to improve this NIR measurement and better understand systematic uncertainties through larger low-z samples, new light-curve models, calibration improvements, and eventually by building high-z samples from the Roman Space Telescope.

Energetic electrons of Jovian origin have been observed for decades throughout the heliosphere, as far as 11 au, and as close as 0.5 au, from the Sun. The treatment of Jupiter as a continuously emitting point source of energetic electrons has made Jovian electrons a valuable tool in the study of energetic electron transport within the heliosphere. We present observations of Jovian electrons measured by the EPI-Hi instrument in the Integrated Science Investigation of the Sun instrument suite on Parker Solar Probe at distances within 0.5 au of the Sun. These are the closest measurements of Jovian electrons to the Sun, providing a new opportunity to study the propagation and transport of energetic electrons to the inner heliosphere. We also find periods of nominal connection between the spacecraft and Jupiter in which expected Jovian electron enhancements are absent. Several explanations for these absent events are explored, including stream interaction regions between Jupiter and Parker Solar Probe and the spacecraft lying on the opposite side of the heliospheric current sheet from Jupiter, both of which could impede the flow of the electrons. These observations provide an opportunity to gain a greater insight into electron transport through a previously unexplored region of the inner heliosphere.

Pseudohynobius flavomaculatus a provincially-protected salamander species, inhabits mountainous areas of Chongqing and surrounding provinces in China. In the present study, the complete mitochondrial genome of P. flavomaculatus was sequenced and analyzed. The mitogenome is 16,401 bp in length and consisted of 13 protein-coding genes, 2 ribosomal RNA genes, 22 transfer RNA genes, and a control region. We performed a novel phylogenetic analysis, which demonstrated a sister relationship between P. flavomaculatus and P. jinfo. The 95% confidence interval around our new divergence date estimate suggest that Hynobiidae originated at 101.62–119.84 (mean=110.87) Ma. Species within Hynobiidae diverged successively in the Cenozoic era, and hynobiid speciation coincides primarily with geologic events. Our biogeographical inference demonstrates that nearly all early hynobiids divergences correspond to geological estimates of orogeny, which may have contributed to the notably high dN/dS ratio in this clade. We conclude that orogeny is likely a primary, dynamic factor, which may have repeatedly initiated the process of speciation in the family Hynobiidae.
Le street art : le débordement autonome
Authors: Genin Christophe
Published: July 2022

Le street art a depuis longtemps une réputation de marginalité, lié aux mauvais lieux des esprits contestataires. La critique d’art, savante ou médiatique, abonde en ce sens, perpétuant une image de pratique rebelle et anticonformiste. Toutefois cette marginalité nous semble douteuse compte tenu de l’histoire de ce mouvement, de l’évolution économique et artistique de certaines pratiques de rue, de la reconnaissance d’un art des rues par le marché de l’art et les institutions culturelles privées et publiques. Examinant les statuts d’une marge et du street art depuis des paramètres proprement artistiques et relevant de l’esthétique, notre propos se centrera sur la notion de débordement .
Les poteries modelées de Sejnane, figures d’une esthétique de la terre peinte
Authors: Sirven Hélène
Published: July 2022

Les potières berbères de Sejnane (Tunisie) produisent depuis toujours des objets domestiques qui sont aussi des objets d’art, de collection, et pas seulement un artisanat. Leur savoir-faire fait partie du patrimoine immatériel de l’Unesco et les artistes, les institutions contemporains sont sensibles à cette pratique ancestrale. Dans cet article, on examine en quoi l’art des potières de Sejnane incarne une poétique, une poïétique, une esthétique qui croisent signes et figurations et interrogent les frontières de l’art, la notion de marge.
En marge de la « marge » japonaise
Authors: Suto Yoshiko , Weigel Frédéric
Published: July 2022

Notre article se propose d’articuler au domaine de l’esthétique notre expérience en tant qu’organisateur d’expositions présentant des artistes internationaux dans un centre d’art indépendant au Japon. En nous basant sur une théorie de la réception des œuvres, nous proposerons une lecture des appréhensions habituelles des modalités courantes au Japon par le renvoi aux formules de Nishida concernant l’acte artistique. Dès lors se croisent deux notions de marginalité. La première renvoie à l’opposition entre philosophie analytique et philosophie existentielle, la seconde consiste à minorer les formes d’art qui ne renvoient pas au bien de la communauté.
Nodal solutions for the Kirchhoff-Schrödinger-Poisson system in $ \mathbb{R}^3 $
Authors: Cheng Kun , Wang Li
Published: July 2022

This paper is dedicated to studying the following Kirchhoff-Schrödinger-Poisson system:

   \begin{document}$ \begin{equation*} \left\{\begin{array}{ll} - \left(a+b \int_{ \mathbb{R}^3} |\nabla u|^2 dx \right) \Delta u+V(|x|) u+\lambda\phi u = K(|x|)f(u), & x \in \mathbb{R}^{3}, \\ -\Delta \phi = u^2, & x \in \mathbb{R}^{3}, \end{array}\right. \end{equation*} $\end{document}

where $ V, K $ are radial and bounded away from below by positive numbers. Under some weaker assumptions on the nonlinearity $ f $, we develop a direct approach to establish the existence of infinitely many nodal solutions $ \{u_k^{b, \lambda}\} $ with a prescribed number of nodes $ k $, by using the Gersgorin disc's theorem, Miranda theorem and Brouwer degree theory. Moreover, we prove that the energy of $ \{u_k^{b, \lambda}\} $ is strictly increasing in $ k $, and give a convergence property of $ \{u_k^{b, \lambda}\} $ as $ b\rightarrow 0 $ and $ \lambda \rightarrow 0 $.
SRV-GAN: A generative adversarial network for segmenting retinal vessels

Published: July 2022

In the field of ophthalmology, retinal diseases are often accompanied by complications, and effective segmentation of retinal blood vessels is an important condition for judging retinal diseases. Therefore, this paper proposes a segmentation model for retinal blood vessel segmentation. Generative adversarial networks (GANs) have been used for image semantic segmentation and show good performance. So, this paper proposes an improved GAN. Based on R2U-Net, the generator adds an attention mechanism, channel and spatial attention, which can reduce the loss of information and extract more effective features. We use dense connection modules in the discriminator. The dense connection module has the characteristics of alleviating gradient disappearance and realizing feature reuse. After a certain amount of iterative training, the generated prediction map and label map can be distinguished. Based on the loss function in the traditional GAN, we introduce the mean squared error. By using this loss, we ensure that the synthetic images contain more realistic blood vessel structures. The values of area under the curve (AUC) in the retinal blood vessel pixel segmentation of the three public data sets DRIVE, CHASE-DB1 and STARE of the proposed method are 0.9869, 0.9894 and 0.9885, respectively. The indicators of this experiment have improved compared to previous methods.
GSTCNet: Gated spatio-temporal correlation network for stroke mortality prediction

Published: July 2022

Stroke continues to be the most common cause of death in China. It has great significance for mortality prediction for stroke patients, especially in terms of analyzing the complex interactions between non-negligible factors. In this paper, we present a gated spatio-temporal correlation network (GSTCNet) to predict the one-year post-stroke mortality. Based on the four categories of risk factors: vascular event, chronic disease, medical usage and surgery, we designed a gated correlation graph convolution kernel to capture spatial features and enhance the spatial correlation between feature categories. Bi-LSTM represents the temporal features of five timestamps. The novel gated correlation attention mechanism is then connected to the Bi-LSTM to realize the comprehensive mining of spatio-temporal correlations. Using the data on 2275 patients obtained from the neurology department of a local hospital, we constructed a series of sequential experiments. The experimental results show that the proposed model achieves competitive results on each evaluation metric, reaching an AUC of 89.17%, a precision of 97.75%, a recall of 95.33% and an F1-score of 95.19%. The interpretability analysis of the feature categories and timestamps also verified the potential application value of the model for stroke.

Treatment of Stenotrophomonas maltophilia infections comprises of sulfamethoxazole/tripethoprim (SXT) or fluoroquinolones. We investigated antimicrobial resistance, presence of resistance genes (sul1, smqnr) and clonal dissemination in S. maltophilia from a university hospital. Among 62 isolates, 45 (73%) represented infection. Two isolates (3%) were resistant to SXT and three (5%) to levofloxacin. Twenty-nine isolates (47%), including two out of three levofloxacin-resistant, carried smqnr. Resistance of S. maltophilia was low and was not associated with sul1 or smqnr carriage. Although high degree of genetic diversity was identified (29 pulsotypes), 22/62 (35.5%) strains were classified into four clones; clone b was associated with bacteraemias.
Quid pro quo: Friendly information exchange between rivals
Authors: Blume Andreas , Park In-Uck
Published: July 2022

We show that information exchange via disclosure is possible in equilibrium even when it is certain that whenever one party learns the truth, the other loses. The incentive to disclose results either from an expectation of disclosure being reciprocated—the quid pro quo motive—or from the possibility of learning from the rival's failure to act in response to a disclosure—the screening motive. Alternating and gradual disclosures are generally indispensable for information exchange and the number of disclosure rounds grows without bound if the agents' initial information becomes sufficiently diffuse; in that sense, the less informed agents are, the more they talk. Patient individuals can achieve efficiency by means of continuous alternating disclosures of limited amounts of information. This provides a rationale for protracted dialogues.
Monotone contracts
Authors: Bird Daniel , Frug Alexander
Published: July 2022

We develop a framework for deriving dynamic monotonicity results in long‐term stochastic contracting problems with symmetric information. Specifically, we construct a notion of
concave separable activity that encompasses many prevalent contractual components (e.g., wage, effort, level of production, etc.). We then provide a tight condition under which such activities manifest a form of seniority in
every contracting problem in which they are present: any change that occurs in the level of the activity over time favors the agent. Our work unifies and significantly generalizes many existing results and can also be used to establish monotonicity results in other settings of interest.
Las tareas del daño
Authors: Thiebaut Carlos
Published: July 2022

Se propone que las experiencias de daño se definen por dos tipos de rasgos. En primer lugar, por un tipo doble de modalidad de la experiencia: a diferencia de la negatividad de lo que tradicionalmente se comprende como mal, el daño se define no por ser necesario o ser experimentado como tal, sino por su posibilidad negativa -lo que no es o era necesario que hubiera sucedido- y por la necesidad práctica de que no vuelva a reiterarse. En segundo lugar, las experiencias de daño se elaboran y trabajan en estructuras relacionales no simétricas de las víctimas o los supervivientes, los victimarios o dañadores y el conjunto de terceras figuras que atienden y se posicionan concernidos ante ellas, cuando ello alcanza a suceder. Por lo primero, los daños se abren a su clausura que se articula, al menos, en tres tareas: las de su cese, las de su cura o reparación y las del compromiso de su no reiteración. Por lo segundo, esas tareas suponen autoridades y responsabilidades diferentes en esas tres figuras que configuran las experiencias de daño.
República y revolución: la crítica de Schlegel a Kant
Authors: Tomassini Fiorella
Published: July 2022

El propósito de este artículo es analizar la crítica de Schlegel a la filosofía política de Kant respecto de dos temas: el ideal republicano y la justificación de la revolución. En el Versuch, Schlegel vincula república y democracia y se opone a la tesis de Kant, según la cual la revolución no es moralmente permisible. La insurrección del pueblo es reivindicada como una forma de acción política autorizada por la voluntad general, con el fin de acelerar la institución de un régimen republicano. Mi argumento es que la postura de Schlegel respecto de la justificación de la revolución se apoya en dos pilares: primero, en una concepción rousseauniana del pueblo como poder constituyente y, segundo, en el rechazo de la doctrina kantiana acerca de la absoluta necesidad racional del Estado.
