Abstract
This study reports preliminary micrometeorological observations in suburban Tangerang, Banten, Indonesia, a rapidly urbanizing area influenced by Jakarta’s expansion. Monitoring micrometeorological conditions is essential to understand the impacts of rapid landscape changes in such transitional zones. Observations were conducted on the rooftop of the STMKG building, 43 m above ground, using an ultrasonic anemometer, global radiation sensor, downward longwave radiation sensor, and an ambient temperature-humidity sensor. Data were logged at a high frequency of 10 Hz over an 8-day period (20–28 March 2024), and mean values were calculated every 30 minutes. Turbulent fluxes were analysed using the eddy covariance method. Results indicate that wind patterns are predominantly influenced by sea and land breezes, with generally low drag coefficients except in the northeast sector. Heat fluxes align with changes in observed radiation, and turbulence statistics confirm the suitability of the site for micrometeorological monitoring in suburban Tangerang. These findings highlight the complex interactions between local meteorological conditions and urban development, offering insight into energy flux dynamics and aerodynamic properties in the area. The research provides a baseline for future studies and continuous observation to better understand the evolving micrometeorological conditions in Tangerang’s suburban environment.- Book : 1472(1)

In this article, for the first time in the extreme conditions of Uzbekistan, in order to reduce farm costs from born male lambs, data on the use of low-frequency laser radiation as one of the biophysical methods is presented and summarized, which, as studies have shown, ensures the normal course of physiological processes in the body of male lambs that fall into a state of stress after separation from their mothers and the cessation of breastfeeding. The work presents reliable data on the positive effect of this method, which also improved the quality indicators of the resulting livestock products.- Book : 173()

In animals, mitosis involves the breakdown of the nucleus. The reassembly of a nucleus after mitosis requires the reformation of the nuclear envelope around a single mass of chromosomes. This process requires Ankle2 (also known as LEM4 in humans) which interacts with PP2A and promotes the function of the Barrier-to-Autointegration Factor (BAF). Upon dephosphorylation, BAF dimers cross-bridge chromosomes and bind lamins and transmembrane proteins of the reassembling nuclear envelope. How Ankle2 functions in mitosis is incompletely understood. Using a combination of approaches in Drosophila, along with structural modeling, we provide several lines of evidence that suggest that Ankle2 is a regulatory subunit of PP2A, explaining how it promotes BAF dephosphorylation. In addition, we discovered that Ankle2 interacts with the endoplasmic reticulum protein Vap33, which is required for Ankle2 localization at the reassembling nuclear envelope during telophase. We identified the interaction sites of PP2A and Vap33 on Ankle2. Through genetic rescue experiments, we show that the Ankle2/PP2A interaction is essential for the function of Ankle2 in nuclear reassembly and that the Ankle2/Vap33 interaction also promotes this process. Our study sheds light on the molecular mechanisms of post-mitotic nuclear reassembly and suggests that the endoplasmic reticulum is not merely a source of membranes in the process, but also provides localized enzymatic activity.- Book : 13()

Neutron-induced reaction cross sections of short-lived nuclei are imperative to understand the origin of heavy elements in stellar nucleosynthesis and for societal applications, but their measurement is extremely complicated due to the radioactivity of the targets involved. One way of overcoming this issue is to combine surrogate reactions with the unique possibilities offered by heavy-ion storage rings. In this work, we describe the first surrogate-reaction experiment in inverse kinematics, which we successfully conducted at the Experimental Storage Ring (ESR) of the GSI/FAIR facility, using the Pb208(p,p′) reaction as a surrogate for neutron capture on Pb207. Thanks to the outstanding detection efficiencies possible at the ESR, we were able to measure for the first time the neutron-emission probability as a function of the excitation energy of Pb208. We have used this probability to select different descriptions of the γ-ray strength function and nuclear level density, and provide reliable results for the neutron-induced radiative capture cross section of Pb207 at energies for which no experimental data exist.

Abstract
Progress in physics understanding and theoretical model development of plasma transport and confinement (TC) in the ITPA TC Topical Group since the publication of the ITER Physics Basis (IPB) document (Doyle et al 2007 Nucl. Fusion
47 S18) was summarized focusing on the contributions to ITER and burning plasma prediction and control. This paper provides a general and streamlined overview on the advances that were mainly led by the ITPA TC joint experiments and joint activities for the last 15 years (see JEX/JA table in appendix). This paper starts with the scientific strategy and scope of the ITPA TC Topical group and overall picture of the major progress, followed by the progress of each research field: particle transport, impurity transport, ion and electron thermal turbulent transport, momentum transport, impact of 3D magnetic fields on transport, confinement mode transitions, global confinement, and reduced transport modeling. Cross references with other Topical Groups are given in order to highlight overlapped topics, such as the 3D effect on the plasma transport in the edge and L-H transition physics. The increasing overlap between the topical groups is a reflection of the progress on integrating the known physics into comprehensive models that are better and better able to reproduce the plasma transport. In recent years, such integration has become increasingly prevalent when considering transport from the SOL, through the edge pedestal, and into the plasma core. In the near future, increased collaboration also with the magneto-hydrodynamic and energetic particles community will be important as we approach burning plasma conditions in next-step fusion devices. A summary of remaining challenges and next steps for each research field is given in the Summary section.- Book : 65(3)

AbstractUltraviolet (UV) photoacoustic microscopy has attracted lots of attention since it can provide histological images for disease diagnosis without any tissue processing or staining, holding great potential for rapid histopathology in hospitals. However, sometimes, the nuclear contrast in the images is relatively low due to the high UV absorption of various surrounding biomolecules (e.g., heme, myoglobin, lipids, etc.), resulting in low diagnostic accuracy. Here, a label‐free dual‐modality imaging system with ultraviolet photoacoustic and auto‐fluorescence (PAAF) microscopy is proposed, which can obtain photon absorption‐induced PA and AF images simultaneously using only one UV pulsed laser. With the opposite contrast acquired in the PA and AF images and the image fusion technique, this proposed PAAF microscopy enables high‐contrast and high‐sensitivity histological imaging for various tissues, even under a low excitation energy of 0.7 nJ and a high pulse‐to‐pulse energy fluctuation of ≈30%. Mouse brain, kidney, liver, lung, and human lung tissues processed by different clinical protocols have been imaged to demonstrate the versatility of PAAF microscopy, showing its promising applications in surgical pathology.- Book : ()
