Exploring TeV Candidates of Fermi Blazars through Machine Learning
Authors: Zhu J. T. , Lin C. , Xiao H. B. , Fan J. H. , Bastieri D. , Wang G. G. 
Published: June 2023

Abstract
In this work, we make use of a supervised machine-learning algorithm based on Logistic Regression (LR) to select TeV blazar candidates from the 4FGL-DR2/4LAC-DR2, 3FHL, 3HSP, and 2BIGB catalogs. LR constructs a hyperplane based on a selection of optimal parameters, named features, and hyperparameters whose values control the learning process and determine the values of features that a learning algorithm ends up learning, to discriminate TeV blazars from non-TeV blazars. In addition, it gives the probability (or logistic) that a source may be considered a TeV blazar candidate. Non-TeV blazars with logistics greater than 80% are considered high-confidence TeV candidates. Using this technique, we identify 40 high-confidence TeV candidates from the 4FGL-DR2/4LAC-DR2 blazars and we build the feature hyperplane to distinguish TeV and non-TeV blazars. We also calculate the hyperplanes for the 3FHL, 3HSP, and 2BIGB. Finally, we construct the broadband spectral energy distributions for the 40 candidates, testing for their detectability with various instruments. We find that seven of them are likely to be detected by existing or upcoming IACT observatories, while one could be observed with extensive air shower particle detector arrays.
The 2021 Activity of the Fast-radio-burst-emitting Galactic Magnetar SGR 1935+2154 as Observed by NASA’s Fermi Gamma-Ray Burst Monitor
Authors: Rehan Noor ul Sabah , Ibrahim Alaa I. 
Published: June 2023

Abstract
The galactic, fast-radio-burst-emitting magnetar SGR 1935+2154 entered an active X-ray burst episode in 2021 September, nearly a year after emitting a fast radio burst with an X-ray counterpart. We report on the temporal and spectral properties of the activity, which included bright intermediate flares, and present a burst catalog of the Fermi Gamma-Ray Burst Monitor observations. We compare this activity to the previous 6 yr history of the source since its discovery in 2014. The bursts show a mean log-Gaussian duration T
100 ∼ 77.34 ms, a cutoff power-law peak energy E
peak ∼ 26.62 keV, and a photon index ΓCPL ∼ 0.49, and blackbody soft and hard temperatures kT
BBs ∼ 5.23 keV and kT
BBh ∼ 9.24 keV, respectively. The burst fluence spans 3 orders of magnitude (10−8–10−5 erg cm−2) and follows

peak) shows a slight softening and is generally softer than other magnetars. We discuss our results in terms of magnetar physics and emission mechanisms.
Horizonless Spacetimes As Seen by Present and Next-generation Event Horizon Telescope Arrays
Authors: Eichhorn Astrid , Gold Roman , Held Aaron 
Published: June 2023

Abstract
We study the capabilities of present and future radio very long baseline interferometry arrays to distinguish black holes from horizonless spacetimes. We consider an example of a horizonless spacetime, obtained by overspinning a regular black hole. Its image is distinct from the image of a Kerr spacetime due to a second set of photon rings interior to the shadow. These photon rings cannot be directly resolved by present and even next-generation Event Horizon Telescope arrays, but instead imprint themselves in horizon-scale images as excess central brightness relative to that of a black hole. We demonstrate that future arrays can decrease the upper bound on the central brightness depression by a factor of 10 and thereby detect such indirect imprints from non-Kerr spacetimes in reconstructed images.
Limits on Leptonic TeV Emission from the Cygnus Cocoon with Swift-XRT

Published: June 2023

Abstract

γ-ray observations of the Cygnus Cocoon, an extended source surrounding the Cygnus X star-forming region, suggest the presence of a cosmic-ray accelerator reaching energies up to a few PeV. The very-high-energy (VHE; 0.1–100 TeV) γ-ray emission may be explained by the interaction of cosmic-ray hadrons with matter inside the Cocoon, but an origin of inverse Compton radiation by relativistic electrons cannot be ruled out. Inverse Compton γ-rays at VHE are accompanied by synchrotron radiation peaked in X-rays. Hence, X-ray observations may probe the electron population and magnetic field of the source. We observed 11 fields in or near the Cygnus Cocoon with the Neil Gehrels Swift Observatory’s X-Ray Telescope (Swift-XRT) totaling 110 ks. We fit the fields to a Galactic and extragalactic background model and performed a log-likelihood ratio test for an additional diffuse component. We found no significant additional emission and established upper limits in each field. By assuming that the X-ray intensity traces the TeV intensity and follows a

spectrum, we obtained a 90% upper limit of F
X < 8.7 × 10−11 erg cm−2 s−1 or <5.2 × 10−11 erg cm−2 s−1 on the X-ray flux of the entire Cygnus Cocoon between 2 and 10 keV depending on the choice of hydrogen column density model for the absorption. The obtained upper limits suggest that no more than one-quarter of the γ-ray flux at 1 TeV is produced by inverse Compton scattering, when assuming an equipartition magnetic field of ∼20 μG.

Abstract
The dramatic changes in the magnetic field at the dipolarization front (DF) provide a suitable environment for electron acceleration, which usually can cause the flux enhancement of energetic electrons behind the front. However, it is unknown whether energetic electrons observed at the DF are energized locally, and which mechanism accelerates the electrons at the DF is unclear. Our study performs a direct quantitative analysis to reveal the acceleration process of energetic electrons at the DF using the high-time-resolution data from NASA's Magnetospheric Multiscale mission. The fluxes of energetic electrons at 90° are enhanced at the front. Under adiabatic conditions, our quantitative analysis indicates that these electrons at the front could be locally accelerated to over 100 keV by betatron acceleration. Eventually, the electron temperature anisotropy formed via the betatron mechanism could provide the free energy to excite whistler waves at the DF. Our quantitative study provides, for the first time, strong direct evidence for the local electron acceleration at the DF.

Quantitative inverse theorem for Gowers uniformity norms and in
Authors: Milićević Luka 
Published: June 2023

AbstractWe prove quantitative bounds for the inverse theorem for Gowers uniformity norms
$\mathsf {U}^5$
and
$\mathsf {U}^6$
in
$\mathbb {F}_2^n$
. The proof starts from an earlier partial result of Gowers and the author which reduces the inverse problem to a study of algebraic properties of certain multilinear forms. The bulk of the work in this paper is a study of the relationship between the natural actions of
$\operatorname {Sym}_4$
and
$\operatorname {Sym}_5$
on the space of multilinear forms and the partition rank, using an algebraic version of regularity method. Along the way, we give a positive answer to a conjecture of Tidor about approximately symmetric multilinear forms in five variables, which is known to be false in the case of four variables. Finally, we discuss the possible generalization of the argument for
$\mathsf {U}^k$
norms.
An Exceptional Presentation of “Watermelon Stomach” in a 30- Year-Old Cirrhotic Male
Authors: Salpekar Radhika , Upadhya Keerthan , Prasad Shiva 
Published: June 2023

Gastric antral vascular ectasia (GAVE) is an unusual cause of chronic upper gastrointestinal bleeding commonly described in elderly females, with associated autoimmune diseases, and in cirrhotic males. The entity is characterized by angioectasia in the pyloric antrum, giving its classic streaky “watermelon stripe” appearance. This report highlights the rare presentation of a 30-year-old male with liver cirrhosis, who presented with anemia and fatigability. Diagnosis of GAVE was made using endoscopy, and trials of argon plasma coagulation were administered. Following this, an antrectomy was performed since there was a further drop in hemoglobin. The patient made a full recovery with no subsequent dependence on blood transfusions. GAVE can be mistakenly underdiagnosed as a treatable cause of occult gastrointestinal bleeding. This report mandates caution on endoscopy for younger patients with an upper gastrointestinal bleed while taking other more common causes of gastrointestinal bleeding (peptic ulcers, esophageal varices, and non-steroidal anti-inflammatory drugs [NSAID]-induced gastritis) into account.

Background: Intestinal parasitic infections (intestinal worms) are major public health problems, especially in developing countries. This study was conducted to determine the prevalence and management strategy of intestinal parasitic infections (IPIs) employed by households.
Methodology: The study was carried out in Imo State, south-eastern Nigeria. Faecal samples from 1200 school children, aged 6-13 years were examined using the Kato Katz method and formol-ether concentration techniques. A structured and pre-tested questionnaire was used to collect data. The level of significance was set at P< 0.05.
Results: The total prevalence of IPIs was 19.3%, which comprises eight parasites namely; Ascaris lumbricoides (3.4%), Trichuris trichiura (1.3%), hookworm (1.8%), Strongyloides stercoralis (0.2%), Taenia spp (0.5%), Entamoeba histolytica (5.3%), Entamoeba coli (3.7%), and Giardia lamblia (4.2%). There was high awareness of possible signs and symptoms of IPIs. Albendazole, Pyrantel pamoate and Mebendazole were the three most frequently used drugs and intermittent deworming with them was effective against the intestinal worm. The impact of deworming on the prevalence of intestinal worms was higher among children dewormed every 4 months, compared with other groups. Self-medication was a major practice amongst the study population. Households (33.9%) delayed up to 48 hours from the onset of symptoms before giving the child medical attention. The majority of households used plant extracts as alternative medication.
Conclusion: The management approaches in the study area were good although they did not regard IPIs as a serious public health problem for a growing child.

Published: June 2023

INTRODUCTION
The COVID-19 pandemic wreaked worldwide havoc resulting in at least 6.9 million deaths. In Kenya, the government laid out behavioural and social mitigation strategies to control its spread. This study aimed to assess adherence to COVID-19 mitigation measures among adults residing in Kitui County, Kenya.
METHODOLOGY
A descriptive cross-sectional study was conducted among households in Kitui Central Sub-County, Kitui County, Kenya sampling 384 participants. Data was collected using a semi-structured questionnaire and observation checklist. Principal Component Analysis, Chi-square and multiple regression were used to assess associations and causation using SPSS version 25.
RESULTS
The response rate was 85%. Almost all (96.6%; n=315) of the participants had heard of COVID-19 and knew that wearing face masks prevents infection (98.5%; n=321). Television was the source of information for most (53.7%, n=175) participants. There was a significant difference (p<.05) between respondents who knew the COVID-19 prevention protocols and those who did not (χ2=0.10; df=1;p=.00).
CONCLUSION
There was a high level of knowledge and a moderate level of practice of COVID-19 prevention protocols. Television was an important medium for community health education. Ministries of health can utilise mass media for continuous population education on COVID-19 and other infectious diseases.

Published: June 2023

BACKGROUND
Stigma compromises the quality of life of people living with HIV/AIDS. There is a critical knowledge gap on how to combat self-stigma among HIV-positives. the study assessed the effectiveness of nurse-led PMTCT health education on self-stigma reduction among HIV-positive women attending PMTCT antenatal clinics in Mombasa County, Kenya.
METHODOLOGY
The study used a two-group, quasi-experimental research design. All pregnant HIV-positive women of reproductive age (18-49) who attended PMTCT prenatal clinics at the selected Mombasa County healthcare facilities were included in the study. A nurse-led health education program on PMTCT was provided at the intervention location but not at the control site. The mean difference in the proportion of mothers who reported self-stigma between the intervention and control groups was computed using a chi-square statistic. To assess the effectiveness of nurse-led PMTCT health education intervention, the difference in difference (DiD) was conducted.
RESULT
Chi-square statistics indicated that there were significantly (χ2=151.096, df=1, p<0.001) more HIV-positive women with low self-stigma in the intervention group compared to the control group at the end-line survey. Nurse-led health education on PMTCT reduced the proportion of self-stigma in HIV-positive women from 62.1% to 10.6%. It thus reduced the proportion of self-stigma in HIV-positive women significantly by 82.6%.
CONCLUSION
Nurse-led PMTCT health education should be integrated with other interventional strategies aimed at reducing self-stigma among HIV-positive women attending PMTCT antenatal clinics

Published: June 2023

The purpose of this study is to statistically evaluate the impact of urban forestry on urban heat Island in Umuahia city, located in Eastern Nigeria using Land Surface Temperature (LST) time series. The LST datasets were extracted from the Moderate Resolution Imaging Spectroradiometer (MODIS, MYD11A2 V6) satellite using Python and JavaScript in Google Earth Engine (GEE) platform. Two microclimate environments were considered namely: The Densely and sparsely populated areas in three different locations each. Each microclimate location had 976 observations starting from the 18th of February 2000 to the 1st of May 2021. The Auto-regressive Moving Average (ARMA) was used to model and predict the time series future points of each location; accuracy was measured using Mean Absolute Percentage Error (MAPE) and Root Mean Square Error (RMSE). The Land surface temperature of each selected microclimate location were monitored and the results showed an average observed temperatures difference of 2.90C between the Densely Populated and Sparsely Populated areas. In conclusion, the study showed that inhabitants of densely populated areas experience higher temperature regime than the inhabitants living within the sparsely populated areas. This increase in temperature within the densely populated could be attributed to the gradual loss of vegetation cover, which is due to man-made activities such as land use, land cover changes, industrial activities, vehicular movements, and the heat generated from buildings within the city. Thus, a spatial development planning strategy, which controls the growth of the built area and add green spaces should be created for a friendly urban environment.
