With inconsistent COVID-19 prevention guidelines being issued across different local governments, an examination of how individual businesses are implementing infection-control interventions on their own is needed. This study assessed the relative compliance of businesses with infection-control guidelines implemented to decrease the spread of COVID-19. Researchers employed an environmental/behavioral checklist to systematically record how the guidelines were followed in community areas where people congregate and risk receiving or spreading COVID-19. Early numbers show that most establishments post signs with guidelines at entrances, require masks for entry, deny entry for symptomatic individuals, and have installed protective barriers between customers and employees. There are also high rates of compliance with mask-wearing guidelines among employees. Future directions include collaboration with other universities for more robust, large-scale data collection and analyses.

Binary cell fate decisions serve at a cornerstone of cellular decision-making processes during embryonic development. Understanding and studying these decisions require an intimate knowledge of the spatial and temporal expression dynamics of critical genes. Split fluorescent proteins (sFP) can serve as a novel tool to study these binary cell fate decisions, with unique applications such as the potential to amplify weak genetic signals. Ultimately, sFPs can be utilized to revolutionize the study of protein-protein interactions during embryonic development and beyond.

A promising chipless RFID approach uses millimeter-wave synthetic aperture radar (SAR) to image metal ink-printed ID tags from a meter or more away. Due to printing cost, it is desirable to minimize the size and spacing of metal patches within a tag, preferably into the subwavelength regime. Although circular SAR (CSAR) has a sharply peaked point response in 2D, its side lobes of closely-spaced targets interfere strongly with each other to distort the image. An alternative 2D subwavelength imaging approach with minimal side lobes is Time-Reversal MUSIC (TR-MUSIC). Traditional TR-MUSIC, however, requires a large number of transmitters and receivers. We propose a hybrid synthetic aperture TR-MUSIC algorithm (SATR-MUSIC) that combines the benefits of both approaches. Using relatively few transceivers, SATR-MUSIC is able to resolve objects separated by approximately in 2D with minimal background artifacts. It does so by averaging TR-MUSIC’s imaging kernel incoherently over the synthetic aperture.

All unmanned aerial vehicles that use synthetic aperture radar (SAR) systems are equipped with inertial navigation systems (INS) to reduce motion error. Additional motion compensation (MOCOMP) from the data itself is still necessary to achieve required accuracy of a SAR. An affordable method for small drones has yet to be created. We propose machine learning with deep convolutional neural network (CNN) to extract motion error such as sway (right and left) and surge (forward). Results show that the CNN is capable of recognizing gradual drone motion deviations. It has the potential to pick up sudden motion error as well, overcoming major deficiencies of traditional MOCOMP methods, and the need for INS.

Black Americans are twice as likely as Nonhispanic Whites to develop Alzheimer’s Disease. In a past study, we found that race modifies the relationship between neuroimaging measures and Alzheimer’s biomarkers between functionally connected regions in the brains of Black Americans. In this study, we aim to replicate these findings in a larger cohort of participants and explore what other factors might be contributing to the observed biomarker-connectivity relationship. We found a marginally significant interaction for race by diagnosis such that Black Americans with dementia had lower connectivity between the precuneus and temporal pole. In contrast, our previous study found that Black Americans had increased connectivity within these regions.

The defensive burying paradigm can inform how stressor controllability affects stress adaptation, which has clinical implications with regards to adaptive coping responses following presentation with a stressful situation. Active coping (notably defensive burying) is associated with a controllable stressor, promoting stress adaptation, thus decreases stress hormone levels. In opposition, chronic stress and uncontrollable stressors lead to an increase in passive coping behaviours, with elevated stress hormone levels. Several brain regions have been implicated in active and passive coping, as well as neurotransmitter systems, which can be evaluated via pharmacological manipulation. No sex differences were found in defensive burying, although there were effects of sex hormones within sex.

The cubic-quintic Ginzburg-Landau equation (CQGLE) governs the dynamics of solitons in lasers and many optical systems. Using data obtained from the simulations of the CQGLE, we performed a singular value decomposition (SVD) to create a low dimensional model that qualitatively predicts the stability of the solitons as a function of the energy gain constant. It was found both in the full simulations and in the low dimensional model that the soliton becomes unstable when the gain exceeds a certain threshold value. Both the low dimensional model and the full simulation demonstrated the same qualitative behavior when the soliton loses stability.

To investigate the impact of writing a gratitude letter on particular mood states, we asked students in two university classes (a research class and a positive psychology class) to complete a 15-item mood assessment survey (MAS) twice a day (once in the morning and once at night). The research students who signed up for one or two pass/fail field-study credits in a research class also completed the MAS twice a day, but they did not write the weekly gratitude letter that was expected from the students in the positive psychology class. Each mood state was averaged per each day for the participants in each group and compared between the Gratitude Group and the Control Group. No group difference occurred for some mood states like “incompetent,” but for the “unmotivated” mood state, a significant difference was found. To investigate the potential effect of weekday, we compared the average mood rating between groups for each day of the week. For the mood state of “unmotivated”, a remarkable dip occurred on Wednesday for the Gratitude group, but not for the Control group. These results indicated that writing a gratitude letter increased the benefactor’s motivation, especially on the day when it was accomplished.

At Bose Institute Prof. Debendra Mohan Bose and his co-workers made globally recognised contributions in the field of cosmic rays including the first recording of mu-meson tracks. Prof. D. M. Bose and Dr. Biva Choudhury did their cosmic ray experiments at the Darjeeling campus of Bose Institute (along with Sandakphu and Pharijong). Presently the Darjeeling campus hosts a National facility for Astroparticle Physics and Space Science. In Kolkata also there is a Centre for Astroparticle Physics and Space Science (CAPSS). In these two campuses, we are still working on the R&D of plastic scintillation detectors for the study of the cosmic rays to preserve the legacy of Prof. D. M. Bose. The only cosmic ray air shower array in the eastern part of India, consisting of seven plastic scintillator detectors is commissioned at an altitude of about 2200~meters above sea level (a.s.l.) in the Eastern Himalayas (Darjeeling) at the end of January 2018. The cosmic ray air shower array has a hexagon shape with six detectors kept at the vertices ofthe hexagon and one at the center of it. The distance between two consecutive detectors is 8 meters. Each detectorelement is made up of four plastic scintillators of dimension 50~cm~$times$~50~cm~$times$~1~cm thereby forming a totalactive area of 1~m$^2$. These scintillators are fabricated indigenously in the Cosmic RayLaboratory (CRL), TIFR, Ooty, India. All four scintillators of a detector are coupled with a singlePhoto Multiplier Tube (PMT) using wavelength shifting (WLS) fibers. A custom-built module withseven inputs is used to generate a multi-fold trigger. Measurement of the number of cosmic ray airshower is going on since the end of January 2018. The secondary cosmic ray flux and its variation overtime are also recorded at the laboratory in Darjeeling using a three-fold coincidence technique withplastic scintillators. All the details of the experimental setup, techniques of measurement are reported earlier. The updates in the results are presented in this article. In this review article, the details of the R&D program of plastic scintillation detectors carried out during the last five years, for the study of cosmic ray is reported.
