A new Cu(II) three-dimensional network with 4,4′-oxybis benzoic acid: structural diversity, EPR, and magnetism
The copper derivative [Cu4(oba)4(H2O)4]∙H2On(1) has been hydro(solvo)thermally synthesized by combining flexible 4,4′-oxybis benzoic acid (oba) and divalent copper nitrate. As a result of the potential coordination modes of carboxylate oxygens from the oba ligand, the aforementioned complex leads to the formation of an interesting 3D framework, as evidenced by single-crystal X-ray diffractometry. Concerning the topology in 1, the dimers [Cu2C4O8] are nodes of a 5-fold 4-connected uninodal net of the type lvt, with point symbol 42.84 and vertex symbol [4.4.84.84.88.88]. The encapsulation of the copper coordination polymer displays a moderate luminescent property. On temperature-dependent magnetic study, it reveals that the magnetic behaviour of 1 can be associated to a strong antiferromagnetic coupling between the two Cu(II) ions
An adaptive p-Q management technique for grid voltage regulation using PV inverter
Network operators are currently exploring how embedded solar generation can assist with voltage regulation in the distribution network, usually by leveraging the inverter's reactive power capability. In highly resistive networks, reactive power alone may not be sufficient, which has motivated researchers to explore how simultaneous adjustment of active (P) and reactive (Q) power can result in better voltage regulation. However, the relevant published methods usually require unavailable network data as inputs and disregard the non-monotonic relation between P/Q power and voltage in resistive networks. This paper explores theoretically this relation and shows that there is always one optimal P/Q ratio that achieves maximum voltage for that particular loading condition. Surpassing this ratio results in voltage deterioration rather than improvement, which poses a risk for the relevant methods in the literature. To fill this gap, this paper introduces a new adaptive P/Q closed-loop voltage regulation scheme for PV systems and other inverter-based resources, which autonomously tracks this optimal ratio without any external inputs. This method guarantees that the resulting voltage would meet the target setpoint if feasible, or will be the maximum possible otherwise. This is the first technique to do this without any prior knowledge about the network. The proposed scheme is validated and assessed over other conventional voltage regulation methods in MATLAB/Simulink.</p
Network-agnostic adaptive PQ adjustment control for grid voltage regulation in PV systems
The service of grid voltage regulation is required nowadays from inverter-based resources (IBRs) particularly at the lower voltage level. In the transmission network, this is easily managed by leveraging solely the reactive power (Q) capability of the IBR, but in distribution networks that are mix of L and r the voltage magnitude is coupled with both active (P) and reactive power injection. There are methods in the literature designed for these cases that utilize both P and Q in voltage regulation, but they usually require network and load data, which may not be readily available. Furthermore, they often disregard an apparent nonmonotonic relation between the inverter terminal voltage and the P/Q ratio risking instability. To fill this gap, this article introduces a network-Agnostic P-Q adjustment technique for photovoltaic (PV) systems or other IBRs. The proposed technique tracks in a step-like manner the reference voltage set point if it is feasible, or the maximum grid voltage otherwise. This allows identification of the critical P/Q ratio without any prior information at the cost of limited voltage ripple due to a variable step-size strategy implemented. The superior performance of the proposed scheme is validated through simulations in MATLAB-Simulink in a reduced UKGDS 95-bus system and through lab experiments on a scaled down laboratory grade prototype.</p
On Petri Nets with Hierarchical Special Arcs
We investigate the decidability of termination, reachability, coverability and deadlock-freeness of Petri nets endowed with a hierarchy of places, and with inhibitor arcs, reset arcs and transfer arcs that respect this hierarchy. We also investigate what happens when we have a mix of these special arcs, some of which respect the hierarchy, while others do not. We settle the decidability status of the above four problems for all combinations of hierarchy, inhibitor, reset and transfer arcs, except the termination problem for two combinations. For both these combinations, we show that deciding termination is as hard as deciding the positivity problem on linear recurrence sequences -- a long-standing open problem

Abstract
India’s pluralistic health architecture formally integrates six traditional systems—Ayurveda, Yoga and Naturopathy, Unani, Siddha, Homoeopathy, and Sowa Rigpa (AYUSH)—within a predominantly allopathic public primary health care system. This scoping review maps the evidence on structural co-location and functional integration of AYUSH in India’s PHC system. Following Arksey & O’Malley (2005) and PRISMA-ScR, 87 records were identified and 17 sources included. Seven thematic domains emerged: historical foundations, coverage (6,158 PHCs, 12,500 AAMs as of 31 March 2025), integrative frameworks, salutogenesis as the “fourth tier”, policy/standards, patient care (>93% improvement reported), and mainstreaming challenges. Co-location has achieved scale but not depth. The evidence calls for functional co-governance, workforce parity, and positioning AYUSH as the salutogenic foundation of Indian PHC via the Ayushman Arogya Mandir framework.

Shoreline changes and its impact on the mangrove ecosystems of some islands of Indian Sundarbans, North-East coast of India
This study aims to analyse the shoreline oscillations of three estuarine Islands in Sundarban delta and its impact on mangrove forests around the Islands. Six multi-temporal Landsat images spanning 42 years (1975–2017) have been used in the study. Band ratio was computed to discriminate the water line from the land, which was later digitized. Digital shoreline analysis system (DSAS) was employed for estimation and analysis of the shorelines changes by End point rate (EPR) model and Linear regression rate (LRR) model after laying transects offshore of the baseline. Sea level and topography of the islands have also been analyzed. To assess the mangrove health, time series Normalized Differential Vegetation Index (NDVI) analysis has been performed using the Mann Kendall Tau statistics and Sen's slope. Mangrove degradation maps were produced from the data and combined with evidences collected from field works. The results point to a very dynamic shoreline ensuing in erosion of mangrove forests while some areas do show encouraging trends due to sustained accretion especially in the southern and eastern parts. Overall erosion is higher than accretion in the Islands. Results show that NDVI has been decreasing along patches that are near to erosion hotspots irrespective of climatic trends. Thus it can be concluded that mangrove forests are under severe stress due to shoreline ingression and sea level rise and not climatic alterations. Going forward this work could provide significant information on the nature of shoreline changes and could assist in sustainable development for Sundarban biodiversity niche management.</p
