Published: March 2023

Abstract
With the increasingly large number of Type Ia supernova being detected by current-generation survey telescopes, and even more expected with the upcoming Rubin Observatory Legacy Survey of Space and Time, the precision of cosmological measurements will become limited by systematic uncertainties in flux calibration rather than statistical noise. One major source of systematic error in determining SNe Ia color evolution (needed for distance estimation) is uncertainty in telescope transmission, both within and between surveys. We introduce here the Collimated Beam Projector (CBP), which is meant to measure a telescope transmission with collimated light. The collimated beam more closely mimics a stellar wave front as compared to flat-field-based instruments, allowing for more precise handling of systematic errors such as those from ghosting and filter angle-of-incidence dependence. As a proof of concept, we present CBP measurements of the StarDICE prototype telescope, achieving a standard (1σ) uncertainty of 3% on average over the full wavelength range measured with a single beam illumination.
2.8 μm pulsed Er3+:ZBLAN fiber laser based on external gain modulation
Authors: Wu J E , Li L , Yang S Q , Li L P , Wang P , Zhao T 
Published: March 2023

Abstract
We report the generation of stable pulses in a ∼2.8 μm Er3+:ZBLAN fiber laser by varying the population inversion of active ions with an external 1973 nm auxiliary pump source. When we increase the 976 nm master pump power to beyond the chaotic self-pulsing stage, stable pulse trains can be obtained immediately with the switch-on of the 1973 nm auxiliary pump source. The pulse repetition rate can be tuned from 22.47 kHz to 63.98 kHz by adjusting the 1973 nm pump power, and the corresponding pulse width is varied from 4.47 μs to 1.99 μs. The underlying mechanism of the pulsed Er3+:ZBLAN fiber laser with external gain modulation is also discussed.
Random sequential covering
Authors: Krapivsky P L 
Published: March 2023

Abstract
In random sequential covering, identical objects are deposited randomly, irreversibly, and sequentially; only attempts increasing the coverage are accepted. A finite system eventually gets congested, and we study the statistics of congested configurations. For the covering of an interval by dimers, we determine the average number of deposited dimers, compute all higher cumulants, and establish the probabilities of reaching minimally and maximally congested configurations. We also investigate random covering by segments with

sites and sticks. Covering an infinite substrate continues indefinitely, and we analyze the dynamics of random sequential covering of

Abstract
We study the long-time asymptotic behavior of the position distribution of a run-and-tumble particle (RTP) in two dimensions in the presence of translational diffusion and show that the distribution at a time t can be expressed as a perturbative series in

, where γ
−1 is the persistence time of the RTP. We show that the higher order corrections to the leading order Gaussian distribution generically satisfy an inhomogeneous diffusion equation where the source term depends on the previous order solutions. The explicit solution of the inhomogeneous equation requires the position moments, and we develop a recursive formalism to compute the same. We find that the subleading corrections undergo shape transitions as the translational diffusion is increased.
Automated, adaptive, fast reset circuit for wide-energy range detector front-end
Authors: Kaczmarczyk P. , Kmon P. 
Published: March 2023

Abstract
In this article, we present a front-end amplifier that is equipped with a precise, fast, and automated reset circuit responsible for two actions: restoring the charge-sensitive amplifier output voltage from a pulse level to baseline, and the analog-to-digital conversion of the pulse amplitude. Importantly, the circuit is self-clocking, which allows to take advantage of the modern submicrometer CMOS process, and thus speed-up the reset and conversion phases. Thanks to the proposed approach, the fast clock signal distribution and an independent analog-to-digital converter per channel are not required, saving both the power consumption and the silicon area. The presented circuitry was adopted into 100-pixel-shaped recording channels and sent for fabrication in the CMOS 28 nm process.
Design and performance optimisation of the Hexaboards for CMS HGCAL silicon sensor readout electronics
Authors: Khan F.A. 
Published: March 2023

Abstract
A new high-granularity endcap calorimeter, HGCAL, is foreseen to be installed later this decade in the CMS experiment. We present the design and performance of the Hexaboard, a complex hexagonal multi-layer PCB equipped with multiple HGCROC ASICs to read out the signals from silicon pads with low noise and large dynamic range. The Hexaboards are glued to silicon sensors and connect to their pads via wire bonds through holes in the PCBs. The Hexaboard also connects to mezzanine boards for powering, trigger and data concentration and transfer. More than ten variants of the Hexaboard are required to cover the circular fiducial area of the CMS endcaps. Detailed performance measurements, and comparative PCB simulations using Ansys SIwave, are presented.
Generalized ILW hierarchy: solutions and limit to extended lattice GD hierarchy
Authors: Takasaki Kanehisa 
Published: March 2023

Abstract
The intermediate long wave (ILW) hierarchy and its generalization, labelled by a positive integer N, can be formulated as reductions of the lattice KP hierarchy. The integrability of the lattice KP hierarchy is inherited by these reduced systems. In particular, all solutions can be captured by a factorization problem of difference operators. A special solution among them is obtained from Okounkov and Pandharipande’s dressing operators for the equivariant Gromov-Witten theory of

. This indicates a hidden link with the equivariant Toda hierarchy. The generalized ILW hierarchy is also related to the lattice Gelfand-Dickey hierarchy and its extension by logarithmic flows. The logarithmic flows can be derived from the generalized ILW hierarchy by a scaling limit as a parameter of the system tends to 0. This explains an origin of the logarithmic flows. A similar scaling limit of the equivariant Toda hierarchy yields the extended 1D/bigraded Toda hierarchy.
Particle entity in the Doi–Peliti and response field formalisms
Authors: Bothe Marius , Cocconi Luca , Zhen Zigan , Pruessner Gunnar 
Published: March 2023

Abstract
We introduce a procedure to test a theory for point particle entity, that is, whether said theory takes into account the discrete nature of the constituents of the system. We then identify the mechanism whereby particle entity is enforced in the context of two field-theoretic frameworks designed to incorporate the particle nature of the degrees of freedom, namely the Doi–Peliti field theory and the response field theory that derives from Dean’s equation. While the Doi–Peliti field theory encodes the particle nature at a very fundamental level that is easily revealed, demonstrating the same for Dean’s equation is more involved and results in a number of surprising diagrammatic identities. We derive those and discuss their implications. These results are particularly pertinent in the context of active matter, whose surprising and often counterintuitive phenomenology rests wholly on the particle nature of the agents and their degrees of freedom as particles.
Small innovation for sustainable use of fisheries resources
Authors: Matsuoka Tatsuro 
Published: March 2023

Abstract
Influenced by Rio Declaration, Code of Conduct for Responsible Fisheries provided the principle toward sustainable fisheries in 1995. Reduction of wastages became a major issue. The author first accessed that the total amount of finfish discards in prawn trawling was similar to the coastal fisheries’ production in PNG and it was serious wastage. He also proved the over-estimation of global discards. A newly developed semi-demersal cuttlefish trammel-net successfully excluded bycatch of sub-legal individuals of flounder. He clarified that the process of declining of ghost fishing function after gear loss for cage trap and gillnet is represented with a survival function, on which the duration of ghost fishing and mortality were quantitatively estimated. He developed a technique for buoy line with an intermediate float to avoid entanglement of the line around seabed rocks. The author advocates research toward small innovation, through which many researchers can contribute to sustainable development.

Abstract
The occurrence of coastal erosion in the coastal area of Karawang Regency has recently been thought to be a disaster, considering the condition is at an alarming status and is a lengthy problem. Hence, an integrated coastal rehabilitation effort is needed to address the impact of coastal erosion in the area effectively and efficiently. The purpose of this study is to develop an integrated management strategy for coastal rehabilitation for coastal erosion control in the coastal area of Karawang Regency by stressing solutions on socio-economic and institutional aspects. This study is a case study conducted through a survey method in the three coastal areas of Karawang Regency that were the most severely affected, namely Cibuaya Beach, Cilebar Beach, and Cilamaya Kulon Beach. Data were collected through observation techniques and in-depth interviews, strengthened by secondary data. Data analysis employed descriptively and decision-making methods of the Analytic Hierarchy Process. The study’s results recommend strategic priorities in managing coastal rehabilitation. Firstly, the coastal border area conservation strategy sets frontiers and rules for managing coastal borders following applicable laws and regulations. Secondly, the social reconciliation and law enforcement strategy facilitate and mediate conflict resolution through deliberation. Thirdly, the strengthening group capacity strategy promotes collaboration between groups of mangrove farmers and related groups to communicate knowledge and experiences. Fourthly, the community education strategy conducts socialization and public awareness of preserving the mangrove ecosystem.

Published: March 2023

Abstract
Aiming at the high temperature and high salinity of Keshen 8 gas reservoir, the selective water plugging agent system with high temperature resistance, salt resistance and water permeability was studied. The effect of the plugging system components on the performance of plugging agent was investigated by single factor experiment, and the best formula was determined. The compressive strength of the material was stable at about 4.6 MPa, and the plugging agent had good temperature and salt resistance. Through the physical simulation experiment of fracture core flow, the plugging effect of different plugging agent injection volume on plugging agent is discussed. When the injection volume is 0.3 PV, the liquid phase plugging rate is 86.69 %, and the gas phase plugging rate is 26.18 %, which has good water resistance and gas permeability.

Published: March 2023

Abstract
This project reports on improving the thermal performance of light-emitting diode (LED) packages based on an optimized thermal structure with a sprayed cuprous oxide coating. Eighteen orthogonal arrays of LED aluminum plates were used and the influence of the parameters of thermal dissipation structure on the LED junction temperature was established. The junction temperature of the LED assembly is developed by various heat dissipation structures based on Taguchi methods. The experimental results show that by measuring the temperature of the 12W LED module, the best results were compared with the lowest values in the overall experiment, where the junction temperature dropped from 67°C to 51°C Also, the contribution of the error to the total variance is about 0.8%, indicating that the experiment is quite successful and robust results. It was found that lower junction temperature values were obtained with optimized heat sink structures with Cu2O-coated Al substrates, and the thermal performance of the LEDs was further improved.
Retinol-Binding Protein 4 Actives Adipocyte Renin–Angiotensin System via Toll-Like Receptor 4
Authors: Zhang Kang-Zhen , Li Xiu-Zhen , Wang Li , Shen Xi-Yu , Zhu Shu-Shu , Lu Xiang , Gao Wei 
Published: March 2023

Abstract

Background
To investigate the relationship between the levels of serum adipokine retinol-binding protein 4 (RBP4) levels and essential hypertension as well as to explore the role and mechanism of RBP4-induced activation of renin–angiotensin system (RAS) in hypertension in adipocyte.

Methods
From December 2016 to March 2019, 96 hypertensive patients without treatment and 64 healthy nonhypertensive subjects were recruited. The difference in serum RBP4 levels between the 2 groups was compared, and the relationship between serum RBP4 and hypertension was analyzed by multivariate logistic regression. In mouse primary white adipocytes, the effect and mechanism of RBP4 on RAS in adipocyte were determined by experiment of adenovirus transfected RBP4 overexpression. Protein expression of Toll-like receptor 4 (TLR4) and RAS key components was determined by western blotting. The level of angiotensin II (Ang II) in cell supernatant was measured by enzyme-linked immunosorbent assay. We also observed the effect of TLR4 inhibitor TAK242 on RAS activation induced by RBP4 overexpression.

Results
Serum RBP4 levels were significantly higher in patients with essential hypertension than in healthy nonhypertensive subjects [30.14 (23.76–40.65) vs. 25.05 (20.05–31.04) µg/ml, P &lt; 0.01]. Multivariate logistic regression analysis showed that RBP4 was independently associated with hypertension [OR 1.10 (95% CI 1.06–1.14), P = 0.002]. In RBP4-transfected adipocytes, the expression of angiotensin-converting enzyme, angiotensinogen, renin/angiotensin-forming enzyme 1, and angiotensin II receptor 1, as well as the level of Ang II in cell supernatant (P &lt; 0.05) were significantly increased. Whereas, activation of RAS system was markedly reduced when RBP4-transfected adipocyte was treated by TAK242 (P &lt; 0.05).

Conclusions
Serum RBP4 is associated with hypertension. TLR4-mediated activation of RAS might be mechanisms underlying the effects of RBP4 on blood pressure.
Targeted optimal treatment regime learning using summary statistics
Authors: Chu J , Lu W , Yang S 
Published: March 2023

SummaryPersonalized decision-making, aiming to derive optimal treatment regimes based on individual characteristics, has recently attracted increasing attention in many fields, such as medicine, social services and economics. Current literature mainly focuses on estimating treatment regimes from a single source population. In real-world applications, the distribution of a target population can be different from that of the source population. Therefore, treatment regimes learned by existing methods may not generalize well to the target popu- lation. Because of privacy concerns and other practical issues, individual-level data from the target population are often not available, which makes treatment regime learning more challenging. We consider the problem of treatment regime estimation when the source and target populations may be heterogeneous, individual-level data are available from the source population and only the summary information of covariates, such as moments, is accessible from the target population. We develop a weighting framework that tailors a treatment regime for a given target population by leveraging the available summary statistics. Specifically, we propose a calibrated augmented inverse probability weighted estimator of the value function for the target population and estimate an optimal treatment regime by maximizing this estimator within a class of prespecified regimes. We show that the proposed calibrated estimator is consistent and asymptotically normal even with flexible semi/nonparametric models for nuisance function approximation, and that the variance of the value estimator can be consistently estimated. We demonstrate the empirical performance of the proposed method using simulation studies and a real application using two datasets on sepsis.
Cortical activity during the wind-up of flexion reflex and pain: a magnetoencephalographic study using time-frequency analysis

Published: March 2023

Abstract
Wind-up is a nociceptive-specific phenomenon in which pain sensations are facilitated, in a frequency-dependent manner, by the repeated application of noxious stimuli of constant intensity, with invariant tactile sensations. Thus, cortical activities during wind-up could be an alteration associated with pain potentiation. We aimed to investigate somatosensory-evoked cortical responses and induced brain oscillations during wind-up by recording magnetoencephalograms. Wind-up was produced by the application of 11 consecutive electrical stimuli to the sural nerve, repeated at a frequency of 1 Hz without varying the intensity. The augmentation of flexion reflexes and pain rating scores were measured simultaneously as an index of wind-up. In the time-frequency analyses, the γ-band late event-related synchronization and the β-band event-related desynchronization were observed in the primary somatosensory region and the bilateral operculo-insular region, respectively. Repetitive exposure to the stimuli enhanced these activities, along with an increase in the flexion reflex magnitude. The evoked cortical activity reflected novelty, with no alteration to these repetitive stimuli. Observed oscillations enhanced by repetitive stimulation at a constant intensity could reflect a pain mechanism associated with wind-up.
Association of serum bicarbonate with the development of kidney stones in patients with chronic kidney disease: a retrospective cohort study
Authors: Tangri Navdeep , Mathur Vandana , Reaven Nancy L , Funk Susan E , Whitlock Reid H , Wesson Donald E , Bushinsky David A 
Published: March 2023

ABSTRACT

Background
Epidemiological studies demonstrate an association between kidney stones and risk of chronic kidney disease (CKD) and CKD progression. Metabolic acidosis, as a consequence of CKD, results in a reduced urine pH which promotes the formation of some types of kidney stones and inhibits the formation of others. While metabolic acidosis is a risk factor for CKD progression, the association of serum bicarbonate with risk of incident kidney stones is not well understood.

Methods
We used an Integrated Claims-Clinical dataset of US patients to generate a cohort of patients with non-dialysis-dependent CKD with two serum bicarbonate values of 12 to &lt;22 mmol/L (metabolic acidosis) or 22 to &lt;30 mmol/L (normal serum bicarbonate). Primary exposure variables were baseline serum bicarbonate and change in serum bicarbonate over time. Cox proportional hazards models evaluated time to first occurrence of kidney stones during a median 3.2-year follow-up.

Results
A total of 142 884 patients qualified for the study cohort. Patients with metabolic acidosis experienced post–index date kidney stones at greater frequency than patients with normal serum bicarbonate at the index date (12.0% vs 9.5%, P &lt; .0001). Both lower baseline serum bicarbonate [hazard ratio (HR) 1.047; 95% confidence interval (CI) 1.036–1.057] and decreasing serum bicarbonate over time (HR 1.034; 95% CI 1.026–1.043) were associated with increased risk of kidney stone development.

Conclusions
Metabolic acidosis was associated with a higher incidence of kidney stones and shorter time to incident stone formation in patients with CKD. Future studies may investigate the role of correcting metabolic acidosis to prevent stone formation.
