Published: March 2023

Abstract
Microfluidic pressure sensors are extensively present in a wide range of applications such as wearable devices, drug detection, and many healthcare applications. Integrated microfluidic pressure sensors are highly desirable in many fields where it offers high sensitivity, non-toxicity, and high biocompatibility. In the present work, an integrated microfluidic pressure sensing mechanism is analyzed in a microfluidic device. The device is composed of poly dimethyl siloxane (PDMS) based material with a microcantilever of the same material integrated on one side of the microchannel. The pressure of fluid in the microchannel is measured by deflection generated on the PDMS microcantilever while the fluid is made to be drive-in. The pressure-based deflection measurement process is analyzed for different types of fluids and the geometry of microcantilevers. The designs for the microcantilevers are considered rectangular-shaped, T-shaped, and Pi-shaped cantilever. The modelling and analysis are done in the commercially available software tool COMSOL Multiphysics®. The results have shown that maximum deflection is achieved with a Pi-shaped microcantilever in fluid plasma (37.05 μm) and in water (30.98 μm) at 8000 μm/s fluid inlet velocity. This maximum deflection was found to be in cooperation with the pressure value at the channel inlet 125.1 Pa for Pi-microcantilever. The optimization is achieved for improved fluid pressure sensing with an integrated microcantilever, which reduces the device setup for fluid pressure analysis. The purpose of research and study is to control fluid pressure inside microfluidic channels, which can pave the way for efficient small setup cytometry and cell separation microfluidic devices.

Abstract
The presence of fringing in astronomical Charge-Coupled Device (CCD) images will have an impact on photometric quality and measurements. Yet its impact on the Vera C. Rubin Observatory’s Legacy Survey of Space and Time (LSST) has not been fully studied. We present a detailed study on fringing for CCDs already implemented on the Rubin Observatory LSST Camera’s focal plane. After making physical measurements and knowing the compositions, we developed a model for the e2v CCDs. We present a method to fit for the internal height variation of the epoxy layer within the sensors based on fringing measurements in a laboratory setting. This method is generic enough that it can be easily modified to work for other CCDs. Using the derived fringing model, we successfully reproduce comparable fringing amplitudes that match the observed levels in images taken by existing telescopes with different optical designs. This model is then used to forecast the expected level of fringing in a single LSST y-band sky background exposure with Rubin telescope optics in the presence of a realistic time-varying sky spectrum. The predicted fringing amplitude in LSST images ranges from 0.04% to 0.2% depending on the location of a CCD on the focal plane. We find that the predicted variation in surface brightness caused by fringing in LSST y-band sky background images is about 0.6

Abstract
We report an all-fiber low threshold (70 mW) multimode Q-switched mode-locked (QML) fiber laser at 1.5

μ

m. Nonlinear polarization rotation and a few mode Er-doped fiber (FM-EDF) were both adopted to achieve a low threshold QML operation initially, and the later experimental results showed and verified that the FM-EDF was the key factor of the QML pulses generation. A multimode QML state at 70 mW pump power was obtained with an 18 μs Q-switched pulse width and a 7.41 kHz repetition rate. The repetition rate and pulse width of the mode-locked pulses within the Q-switched envelope were 16.9 MHz and ∼910 ps respectively. The multimode QML fiber laser can be turned from 1561.8 nm to 1575.1 nm owing to the multimode interference and the fiber birefringence filtering effect. The QML pulses with dual-wavelength and three-wavelength were also observed by manipulating the polarization controllers and increasing the pump power. The experimental results showed that multimode QML pulses can be achieved with a short FM-EDF at a lower pump power in an all-fiber multimode cavity. The generated low threshold and tunable QML multimode fiber laser has potential application in measuring and mode-division multiplexed system.

Conceptual design of multichannel fast electron bremsstrahlung detection system to study fast electron dynamics during lower hybrid current drive in ADITYA-U tokamak
Authors: Kumar Jagabandhu , Pandya Santosh P. , Sharma P.K. 
Published: March 2023

Abstract
To drive plasma current non inductively, a Lower Hybrid
Current Drive (LHCD) system with a passive-active multijunction
(PAM) antenna for injecting lower hybrid wave (LHWs) has been
designed, fabricated and to be integrated with ADITYA-U Tokamak. A
fast electron population in the energy range of a few keV to several
hundreds of keV is generated with the injection of the LHWs. These
fast electrons interacting mainly with ions and electrons result in
Hard X-Ray (HXR) emission called Fast Electron Bremsstrahlung
acronym as FEB emission. A single channel FEB detection system is
being used in the earlier experiment of LHCD in ADITYA-U
tokamak. However, the single channel detection system can't provide
a radial emissivity profile of HXR intensity distribution. In order
to determine a radial emissivity profile, for the first time, a
multichannel FEB detection system is designed for ADITYA-U
tokamak. This paper describes the detailed conceptual design for the
selection of suitable detectors, optimization of the collimators,
shielding geometry, and low energy filtering cut-off. In the present
design analysis, the soller collimator concept is considered over a
simple pinhole camera system due to its several advantages. In order
to optimize the multichannel FEB system parameters for the best
possible performance, a forwarded modelling code has been used. The
signal to background ratio at each detector location has been
estimated for a few system parameters and reported herein.
Ability of spatial filters to distinguish between two MUAPs generated from MUs with different locations, sizes and fibers pennation
Authors: Messaoudi Noureddine , Belkacem Samia , Bekka Raïs El'hadi 
Published: March 2023

Abstract
In this study, we investigated the effects of the motor unit
(MU) location and size and the fibres pennation on the ability of
anisotropic and almost isotropic spatial filters used to detect
surface electromyographic (EMG) signals to make a distinction
between motor unit action potentials (MUAPs) generated from two
MUs. The study was based on simulated MUAPs. The fibres orientation
was performed by varying the fibres pennation angle (FPA).
The root mean square error (RMSE) between MUAPs generated from two
MUs was used as a criterion to evaluate the ability of the
investigated filters to distinguish between two generated MUAPs. The
location of a MU was fixed and the second MU moved away from the
first MU in the transversal direction for the first case and in the
depth direction in the second case to take five different locations
in every case.
We showed that the capability of the studied filters to more
separate two MUAPs strongly depended on MU location, MU size and
FPA. This capability of separation was best with large distances
between the two MUs and with large sizes of them. Furthermore, the
main survey of this work was that the BiTDD filter has the best
ability of separation of two MUAPs than the other filters in a given
FPA interval. The number of pennation angles in this interval is
related to the location and size of the moved MU.
Towards a mathematical theory of the Madelung equations: Takabayasi’s quantization condition, quantum quasi-irrotationality, weak formulations, and the Wallstrom phenomenon
Authors: Reddiger Maik , Poirier Bill 
Published: March 2023

Abstract
Even though the Madelung equations are central to many ‘classical’ approaches to the foundations of quantum mechanics such as Bohmian and stochastic mechanics, no coherent mathematical theory has been developed so far for this system of partial differential equations. Wallstrom prominently raised objections against the Madelung equations, aiming to show that no such theory exists in which the system is well-posed and in which the Schrödinger equation is recovered without the imposition of an additional ‘ad hoc quantization condition’—like the one proposed by Takabayasi. The primary objective of our work is to clarify in which sense Wallstrom’s objections are justified and in which sense they are not, with a view on the existing literature. We find that it may be possible to construct a mathematical theory of the Madelung equations which is satisfactory in the aforementioned sense, though more mathematical research is required. More specifically, this work makes five main contributions to the subject: First, we rigorously prove that Takabayasi’s quantization condition holds for arbitrary C
1-wave functions. Nonetheless, we explain why there are serious doubts with regards to its applicability in the general theory of quantum mechanics. Second, we argue that the Madelung equations need to be understood in the sense of distributions. Accordingly, we review a weak formulation due to Gasser and Markowich and suggest a second one based on Nelson’s equations. Third, we show that the common examples that motivate Takabayasi’s condition do not satisfy one of the Madelung equations in the distributional sense, leading us to introduce the concept of ‘quantum quasi-irrotationality’. This terminology was inspired by a statement due to Schönberg. Fourth, we construct explicit ‘non-quantized’ strong solutions to the Madelung equations in two dimensions, which were claimed to exist by Wallstrom, and provide an analysis thereof. Fifth, we demonstrate that Wallstrom’s argument for non-uniqueness of solutions of the Madelung equations, termed the ‘Wallstrom phenomenon’, is ultimately due to a failure of quantum mechanics to discern physically equivalent, yet mathematically inequivalent states—an issue that finds its historic origins in the Pauli problem.

Abstract
The Painlevé equations possess transcendental solutions y(t) with special initial values that are symmetric under rotation or reflection in the complex t-plane. They correspond to monodromy problems that are explicitly solvable in terms of classical special functions. In this paper, we show the existence of such solutions for a q-difference Painlevé equation. We focus on symmetric solutions of a q-difference equation known as

Existence of the FS-type renormalisation fixed point for unidirectionally-coupled pairs of maps
Authors: Burbanks Andrew , Osbaldestin Andrew 
Published: March 2023

Abstract
We give the first proof of the existence of a renormalisation fixed-point for period-doubling in pairs of maps of two variables lying in the so-called Feigenbaum-Summation (FS) universality class. The first map represents a subsystem that is unimodal with an extremum of degree two. The dynamics of the second map accumulates an integral characteristic of the dynamics of the first, via a particular form of unidirectional coupling. We prove the existence of the corresponding renormalisation fixed point by rigorous computer-assisted means and gain tight rigorous bounds on the associated universal constants. Our work provides the first step in establishing rigorously the picture conjectured by Kuznetsov et al of the birth, from the FS-type fixed point, of the so-called C-type two-cycle via a period doubling in the dynamics of the renormalisation group transformation itself.

Published: March 2023

Abstract
In this research work an attempt was made to reinforce AA7075 composites with B4C and SiC particles through stir casting route. SEM with EDS mapping revealed that the reinforcement were uniformly over the composites and hardness reduces with the addition of SiC particles owing to the inverse hall petch effect. The results revealed that wear rate reduces with addition of SiC particles owing to the formation of mechanically mixed layer and protective oxide layer confirmed through SEM with EDAX mapping. Three distinct cracks were formed, when slides at different temperature as confirmed through worn surface morphology, pits cracks and plasticization of material were the other features observed. The used motor oil properties were analyzed and results divulged that the oil suitable for dielectric fluid. Increase in Material Removal Rate (MRR), reduction in Tool Wear Ratio (TWR) and Surface Roughness (Ra) was observed with the incorporation of powder particles owing to the bridging effect. Black spots, craters, micro pits, globules and micro crack are the distinct observed on the machined surface topography. The modified Preference Ranking Organization METHod for Enrichment of Evaluations (PROMETHEE) optimization technique was utilized to find the optimal parametric combination.
Extinction Threat to a Previously Undescribed Species of Gall Wasp (Hymenoptera: Cynipidae) and Two Associated Parasitoid Species (Hymenoptera: Braconidae and Eulophidae) on a Threatened Rose
Authors: Abe Yoshihisa , Ide Tatsuya , Matsuo Kazunori , Maeto Kaoru , Wu Yajiao 
Published: March 2023

Abstract
Diplolepis ogawai Abe and Ide sp. nov. (Hymenoptera: Cynipidae) induces galls on Rosa hirtula (Regel) Nakai (Rosales: Rosaceae), which is endemic to a restricted area of Honshu, the main island of Japan. The gall is induced mainly on the leaf of R. hirtula in spring and the mature gall falls to the ground in early summer. The gall-inducing wasp emerges from the gall on the ground in the following spring, suggesting that D. ogawai is univoltine. From spring to summer, the braconid Syntomernus flavus Samartsev and Ku and the eulophid Aprostocetus sp. are parasitic on the larva of D. ogawai in the gall, and the adult wasp of both parasitoid species emerges from the gall on the ground in summer. For S. flavus, this is the first distribution record in Japan and the first host record. Since R. hirtula is threatened with extinction by succession and deforestation, D. ogawai and its two parasitoid wasp species are considered to be at risk of coextinction with the threatened rose. In the event that the population size of this rose species is further reduced, D. ogawai and its parasitoids may ­become extinct prior to the extinction of R. hirtula. To conserve these three wasp species associated with R. hirtula, protection of remnant vegetation where individuals of this threatened rose species grow is necessary.
The Aesthetics of Crossword Puzzles
Authors: Kubala Robbie 
Published: March 2023

Abstract
This paper develops an aesthetics of crossword puzzles. I present a taxonomy of crosswords in the Anglophone world and argue that there are three distinct sources of aesthetic value in crosswords. First, and in common with other puzzles, crosswords merit aesthetic experiences of our own agency: paradigmatically, the aesthetic experience of struggling for and hitting upon the right solution. In addition to instantiating the aesthetic value of puzzles in general, crosswords in particular can have two other sources of aesthetic value: the visual appeal of grid art and the poetic delight of idiomatic language. Crossword aesthetics takes place at the intersection of the recently popular aesthetics of puzzles and games and the more familiar aesthetics of the visual and literary arts.
Implementation and outcomes of an ambulatory care pharmacist service: Application of an implementation science framework
Authors: Foster Brooke , Spillane Jordan , Abuzoor Anas , Zraik Mahadi 
Published: March 2023

Abstract

Purpose
As teams work to optimize the pharmacist’s role on care teams, it is important to be proactive and strategic during the service creation process. Implementation science frameworks can help guide pharmacists as they work to translate evidence-based interventions into practice.

Summary
When a care gap in respiratory chronic disease state management in the primary care setting was identified, a team was created to investigate whether an ambulatory care pharmacist service would be a valuable way to address the care gap. This paper outlines the steps taken to scope and implement a new pharmacist service. An implementation science framework, the Exploration, Preparation, Implementation, Sustainment (EPIS) framework, was used to guide the service implementation process. Postimplementation data were collected to assess the impact of the service. A total of 56 patients were managed by the pharmacist in the first year following implementation. Data suggested that the pharmacist service has clinical value based on an improvement in chronic obstructive pulmonary disease (COPD) symptom control, rescue inhaler use, adherence, and inhaler technique. The data also informed postimplementation changes for continuous quality improvement.

Conclusion
The use of an implementation science framework to implement a new pharmacist service proved valuable. Although this project focused on addressing a care gap in COPD, implementation science frameworks can and should be used to guide the implementation of a variety of new clinical services to enhance impact and sustainability.
Sodium-glucose cotransporter 2 inhibitors and cardiovascular clinical outcomes in acute heart failure: A narrative review
Authors: Rodriguez Ryan , Kaluzna Stephanie Dwyer 
Published: March 2023

Abstract

Purpose
This review describes the evidence from randomized controlled trials (RCTs) regarding the effects of sodium-glucose cotransporter 2 (SGLT2) inhibitors on cardiovascular (CV) clinical outcomes when therapy is initiated during acute heart failure (HF).

Summary
SGLT2 inhibitors have become a cornerstone of guideline-directed medical therapy (GDMT) for type 2 diabetes mellitus, chronic kidney disease, and HF. Because of their ability to promote natriuresis and diuresis as well as other potentially beneficial CV effects, use of SGLT2 inhibitors has been investigated when therapy is initiated during hospitalization for acute HF. We identified 5 placebo-controlled RCTs that reported CV clinical outcomes incorporating one or more components of all-cause mortality, CV mortality, CV hospitalization, HF worsening, and hospitalization for HF in patients treated with empagliflozin (n = 3 trials), dapagliflozin (n = 1 trial), and sotagliflozin (n = 1 trial). Nearly all CV outcomes in these trials showed benefit with SGLT2 inhibitor use during acute HF. Incidence of hypotension, hypokalemia, and acute renal failure was generally similar to that with placebo. These findings are limited by heterogeneous outcome definitions, variation in time to SGLT2 inhibitor initiation, and small sample sizes.

Conclusion
SGLT2 inhibitors may have a role in inpatient management of acute HF, provided there is close monitoring for fluctuations in hemodynamic, fluid, and electrolyte status. Initiation of SGLT2 inhibitors at the time of acute HF may promote optimized GDMT, continued medication adherence, and reduced risk of CV outcomes.

Published: March 2023

Abstract
Attachment and resilience are crucial in parent–child interaction. In this study, we investigated the effect of a mindful parenting program on the attachment of deaf children and the resilience of their hearing mothers. The present study was a semi-randomized controlled trial design. Thirty mothers with deaf children were randomly selected from Deaf School in Tehran, Iran. They were randomly assigned to intervention (n = 15) and control (n = 15) groups. The intervention group participated in an eight-session mindful parenting program, while the control group did not participate in this program. Both groups completed the Kinship Center Attachment Questionnaire and Connor-Davidson Resilience Scale before and after the intervention. The data were analyzed using the repeated measures analysis of variance test. The results showed that the intervention significantly and positively influenced the attachment of deaf children and resilience in their mothers in the post-test, and the persistence of this effect was maintained in the follow-up stage (p &lt; .001). This study suggests that mindful parenting can promote attachment of deaf children and resilience in their mothers. In addition, the mothers attested to the social validity of the program.
