Prolonged exposure to freezing stress reduces the ability of chickpea seedlings to effectively tolerate extremely low temperatures

The duration and intensity of freezing stress are the most critical factors determining injury in autumn chickpeas, limiting their production and development. To evaluate the effects of freezing temperature and duration on the survival rate (SU%), as well as the physiological and biochemical characteristics of autumn chickpea seedlings, a study was conducted using five different temperatures (0, -6, -8, -10, and -12°C) and five different durations (1 h, 2 h, 3 h, 4 h, and 5 h) of exposure to freezing stress. The SU% of chickpea seedlings decreased to zero after exposure to temperatures of -10°C and -12°C for 5 hours. As the temperature decreased from -8°C to -12°C and the duration of exposure to freezing stress increased from 1 to 5 hours, the leaf membrane stability index decreased by 33%, 48%, 46%, 57%, and 58%, respectively. The highest and lowest total pigment contents were observed after 1 hour at 0°C and 5 hours at -12°C, respectively. The maximum photochemical efficiency of photosystem II (Fv’/Fm’) was not affected by temperatures as low as -8°C in any of the time treatments during the recovery period. However, this parameter’s value decreased as the freezing stress duration increased. At -12°C, the activity of ascorbate peroxidase, catalase, and peroxidase increased by 44.6%, 38.3%, and 33.0%, respectively, as the duration of stress was increased from 1 hour to 5 hours. A positive and significant correlation was observed between plant dry weight, membrane stability index, photosynthetic pigment content, and Fv’/Fm’ with SU% after exposure to freezing stress. The minimum temperature and the maximum duration of freezing stress tolerance in chickpea seedlings were observed at -12°C for two hours. Our findings confirm that prolonging the freezing duration disrupts the defense mechanisms of chickpea seedlings. Therefore, future studies on breeding chickpeas tolerant to freezing stress should concentrate on attributes strongly correlated with SU%.
Augmented feedback modes during functional grasp training with an intelligent glove and virtual reality for persons with traumatic brain injury

Introduction: Physical therapy is crucial to rehabilitating hand function needed for activities of daily living after neurological traumas such as traumatic brain injury (TBI). Virtual reality (VR) can motivate participation in motor rehabilitation therapies. This study examines how multimodal feedback in VR to train grasp-and-place function will impact the neurological and motor responses in TBI participants (n = 7) compared to neurotypicals (n = 13). Methods: We newly incorporated VR with our existing intelligent glove system to seamlessly enhance the augmented visual and audio feedback to inform participants about grasp security. We then assessed how multimodal feedback (audio plus visual cues) impacted electroencephalography (EEG) power, grasp-and-place task performance (motion pathlength, completion time), and electromyography (EMG) measures. Results: After training with multimodal feedback, electroencephalography (EEG) alpha power significantly increased for TBI and neurotypical groups. However, only the TBI group demonstrated significantly improved performance or significant shifts in EMG activity. Discussion: These results suggest that the effectiveness of motor training with augmented sensory feedback will depend on the nature of the feedback and the presence of neurological dysfunction. Specifically, adding sensory cues may better consolidate early motor learning when neurological dysfunction is present. Computerized interfaces such as virtual reality offer a powerful platform to personalize rehabilitative training and improve functional outcomes based on neuropathology.
Efficacy and safety of Chinese herbal medicine in post-stroke epilepsy: a systematic review and meta-analysis

Background: Poststroke epilepsy (PSE) is a common complication of strokes that seriously affects the recovery and quality of life of patients, and effective treatments are needed. Chinese herbal medicine (CHM) adjunctive therapy is a viable treatment option, but current evidence is insufficient to support its efficacy and safety. This study aimed to evaluate the efficacy and tolerability of CHM adjunctive therapy in the treatment of PSE. Methods: A systematic search of eight databases was conducted to identify PSE-related randomized clinical trials from the inception of each database through October 2023. The methodological quality assessment was conducted by RoB 2.0, meta-analysis was conducted by RevMan 5.3 and Stata 15.1, and evidence quality was evaluated by GRADE. Results: Twenty-three RCTs involving 1,901 PSE patients were identified. We found that orally administered CHM plus conventional Western medicine (CWM) was superior to CWM monotherapy in increasing the 75% responder rate (RR 1.46, 95% CI: 1.31 to 1.62, p < 0.00001), decreasing the seizure duration (MD -1.01, 95% CI: −1.30 to −0.72, p < 0.00001), improving total responder rate (RR 1.29, 95% CI: 1.20 to 1.37, p < 0.00001), reducing epileptiform discharges (EDs) (MD -2.02.46, 95% CI: −2.64 to −1.40, p < 0.00001), and decreasing the number of leads involved in epileptiform discharge (MD -3.92, 95% CI: −5.15 to −2.68, p < 0.00001). Furthermore, intravenously administered CHM plus CWM was superior regarding 75% responder rate (RR 1.39, 95% CI: 1.24 to 1.56, p < 0.00001), total responder rate (RR 1.29, 95% CI: 1.20 to 1.39, p < 0.00001), EDs (MD -3.92, 95% CI: −5.15 to −2.68, p < 0.00001), and the number of leads involved in epileptiform discharge (MD -1.82, 95% CI: −2.62 to −1.02, p < 0.00001). However, regarding the 50%–75% responder rate, there was no statistically significant difference between the two groups for either oral (RR 1.00, 95% CI: 0.77 to 1.29, p = 0.98) or injectable CHM (RR 0.95, 95% CI: 0.67 to 1.33, p = 0.75). Both orally administered CHM plus CWM (RR 0.56, 95% CI: 0.35 to 0.90, p = 0.02) and intravenously administered CHM plus CWM (RR 0.64, 95% CI: 0.45 to 0.90, p = 0.010) caused fewer AEs than CWM. Furthermore, the levels of evidence ranged from low to high due to publication bias and heterogeneity. Conclusion: CHM adjuvant therapy may be an effective and safe therapy for PSE. However, due to the poor quality of clinical data, more well-designed RCTs are needed to confirm these findings.

Attaining the maximum Bose–Einstein condensation in a finite-size hard-core boson model

We propose a model for hard-core bosons in a lattice which allows to achieve the optimal occupation number predicted by Tennie et al (2017 Phys. Rev. B 96 064502) for a finite number of sites. The model is based on an extension of the Hamiltonian of the so-called Hubbard star, whose quantum properties are studied by means of quantum information descriptors such as the von Neumann entropy and the mutual information. These metrics are analyzed as a function of the one- and two-particle reduced density matrices, allowing to explore the relationship between condensation and entanglement by means of a control parameter that, under a given limit, connects our findings with previous results. All developments comprised in this article have been derived by analytical methods.
JAKARTA MASS RAPID TRANSIT PROJECT: AN ECONOMIC REVIEW

Jakarta is the capital city of Indonesia. The growth of Jakarta is increasing, bringing with it paralyzing traffic congestion. The city has responded by planning to build a modern subway system (mass rapid transit system), connecting Blok M and Setasiun Kota. This system is believed by many to be able to solve congestion, particularly, in the North-South corridor of the city. The subway system is an ideal transportation system for big cities like Jakarta. To civic and political leaders it promises glamour and sophistication, and to urban planners it promises resolution of overwhelming traffic congestion. However, there are some aspects that need to be reviewed carefully before the implementation of the plan. Those aspects could be far more difficult and costly than was ever imagined in the planning phase. This paper explores the rationale for the Jakarta Subway Project. The discussion includes the need to have a subway transportation system, the benefits to the city, and the cost to build it. It is partly true that the subway system, which has a great capacity to move people, is the only system, which can be used to solve chaotic road conditions in Jakarta, since no other urban transportation mode has a bigger capacity to move people than this one. However, the financial and economic viability associated with this project need to be justified carefully.
Artificial Neural Networks Application to Predict Wheat Yield Using Climatic Data

The goal of this study was to apply artificial neural networks to predict rain-fed wheat yield using meteorological data a few days to few months before harvesting. The climatic observation data used; were mean of daily minimum and maximum temperature, extreme of daily minimum and maximum temperature, sum of daily rainfall, number of rainy days, sum of daily sun hours, mean of daily wind speed, extreme of daily wind speed, mean of daily relative humidity, and sum of daily water requirements that were collected during 1990-1999 in Sararood Station for wheat phenological stages consisting; sowing, germination, emergence, 3 rd leaves, tillering, stem formation, heading, flowering, milk maturity, wax maturity, full maturity, separately for each growing season. Then, they arranged in a matrix whose rows form each of the statistical years and the columns are meteorological factors at each phenological stage. Finally, the obtained model had the following capabilities: Prediction of wheat yield with maximum errors of 45-60 kg/ha at least two months before full maturity stage, determination of the sensitivity of each phenological stage with respect to meteorological factors, and determination of the priority order and importance of each meteorological factor effective in plant growth and crop yield.
STRUCTURE OF THE CUMBERLAND PLATEAU, TENNESSEE

Present structure of the Cumberland Plateau results from two components: (1) regional eastward dip of about 25 feet per mile off the Cincinnati arch; and (2) Pine Mountain, Cumberland Plateau, and Sequatchie Valley bedding thrusts, which strike north-eastward and have roots in the Valley and Ridge province to the southeast. Gentle eastward dip off the flank of the Cincinnati arch is the only structure affecting the undisturbed portion of the plateau, and is also the primary component of structure in the faulted area. Bedding thrusts do not disturb the position and attitude of strata within the thrust sheets. Locally, however, where the faults cut across bedding, superficial anticlines are formed. The structural concordance between the undisturbed areas and areas of bedding thrusts supports the “no-basement” interpretation for the essential regional structure. Movement of the Cumberland Plateau overthrust sheet over steep portions of its generally flat fault plane caused superficial flat-topped, steep-sided anticlines similar to the Powell Valley anticline of the Pine Mountain overthrust. Abrupt ends of such anticlines mark places where buried steep thrusts become buried strike-slip faults. The oldest thrust is the northwest-dipping Whetstone Mountain fault; next is the Cumberland Plateau overthrust; the youngest thrusts are the Seauatchie Valley thrust and some faults of the Valley and Ridge province.

What Plant Genetic Resources for Food and Agriculture Are Available under the Plant Treaty and Where Is This Information?

Plant genetic resources for food and agriculture (PGRFA) are the building blocks upon which global food and nutrition security depend and are key to plant breeding for more resistant crops, but how available are they? To understand what PGRFA are available under the mechanisms created by the International Plant Treaty’s access and benefit-sharing, we conducted a comparative analysis of the five largest sources of pooled global data concerning PGRFA, including data conserved by and available to users under the Plant Treaty’s access and benefit-sharing (ABS) mechanism. These data sources were the registry of notification letters maintained by the Plant Treaty Secretariat and four international PGRFA databases: Genesys, European Search Catalogue for Plant Genetic Resources (EURISCO), World Information and Early Warning System on Plant Genetic Resources for Food and Agriculture (WIEWS) and Global Information System on PGRFA (GLIS). Our analysis revealed that a comprehensive and consistent overview of the PGRFA available under the Plant Treaty’s ABS conditions is not available. The GLIS is the most logical longer-term candidate to promote the provision of up-to-date and comprehensive snapshots of what PGRFA the Plant Treaty framework make available, primarily because it provides a mechanism (digital objective identifiers) to link together information from a range of information sources, including Genesys, WIEWS and EUEISCO and other online publications, and data sets concerning PGRFA in the multilateral system. Successful adoption of the GLIS could be promoted by creating novel incentives endorsed by the Governing Body to encourage Contracting Parties, Article 15 organizations, and individuals to share information about the materials they are making available under the Plant Treaty, in addition to the capacity-building for some GLIS users that is also necessary. These incentives could be included among the package of measures currently being considered by the Plant Treaty’s Working Group to Enhance the Functioning of the Multilateral System of Access and Benefit-Sharing.
CLIMATE AND PRIMARY PRODUCTIVITY OVER THE LAST 500 YEARS OF THE CHENGHAI LAKE,YUNNAN

Chenghai Lake,a closed eutrophic lake,is situated in Yunnan Plateau.Here the primary productivity trends of the Chenghai lake for the past 500 years were reconstructed by using sediment pigments from core CH01.Oscillaxanthin (Osc)is a pigment unique to the Oscillatoriaceae and has been found in only one genus apart from Oscillatoria . In contrast,Myxoxanthophyll (Myx) is found in most blue green algal genera and in all six families examined.The Chlorophyll derivatives (CD)and total carotenoids (TC) are frequently used in palaeolimnology to reconstruct past levels of primary productivity.In the Chenghai Lake core,the most obvious stratigraphic change in pigment concentration is the dramatic rise in Oscillaxanthin and Myxoxanthophyll beginning at 15 cm. Moreover,high CD and TC values following high Myx and Osc values above 45 cm,allude to higher production.However,high CD and TC values and relatively lower Myx and Osc and CD/TC,correlate with good preservation. During the last 500 years,Chenghai Lake has undergone major increases in productivity and eutrophication in response to the variations in the lake level from agriculture in the lake's watershed.The results showed that the primary productivity generally increased for the recent 500 years,during which there were two abrupt transitions at about 1700 and 1790AD respectively.In addition,from pigment evidences two warm events were demonstrated at about 1750 and 1930AD respectively.
Comparison of pollen-slide and sieving methods in lacustrine charcoal analyses for local and regional fire history

The charcoal content from laminated lake sediments in Québec, Canada, was estimated from pollen slides and by a sieving method. The resulting charcoal series are compared to estimate the suitability of these two methods to provide a local or regional fire history. The replication of five different charcoal series from the sieving method shows that this method is suitable for fire-history reconstruction. In our laminated sediments, 1cm3 is representative of the charcoal content of the sediment. The large charcoal fragments above 15600 mm2are too scarce, however, to provide a significant charcoal series. Comparison of the sieving charcoal series versus the pollen-slide charcoal-series shows that the two series display a roughly similar pattern. The differences between the two series probably result from the accumulation of small particles that have a regional source area and are transported by air over long distances and from high fragmentation rates due to laboratory treatment. Spectral analysis for the last 2000 years shows that the sieving charcoal series have no significant periodic accumulation rate, whereas the spectral analysis of the pollen-slide charcoal series shows a significant period of about 500 years. Because the charcoal particles from the sieving method are larger than those from the pollen-slide method, which are potentially windborne over long distances, our study suggests that the sieving method series is a proxy of local fire history, whereas the pollen-slide method is more suitable for detecting regional trends in fire history.
Characterisation of suspended matter in river systems: River Sava in Slovenia case study

d13C and d15N values in suspended matter were used to examine the seasonal (late summer 2004 and spring 2005) relationship with hydrological characteristics of the River Sava watershed in Slovenia. d13C values range from 29.2 to 23.0 ‰ and d15N values from 0.5 to 16.7 ‰ and indicate that the samples are a mixture of two end members: modern soils and plant litter. A simple mixing model was used to indicate that soil organic carbon prevails over plant litter and contributes more than 50 % of suspended material. The total suspended solid flux (TSS) is estimated to be 1.3 × 1012 g/year. Anthropogenic impact was detected only in a tributary stream of the River Sava which is located in an agriculture-industrial area and is reflected in higher d15N values in suspended matter in the late summer season.

Compact Wide-Beam Scanning Dual-Polarized mmWave Array for Mobile Terminals

A compact wide-beam scanning dual-polarized (DP) array is designed for millimeter-wave (mmWave) applications in mobile terminals. The element is a coupled shorted patch antenna with quarter-wavelength resonance. Orthogonally slot coupled feeding is used to achieve the DP radiation. A close element distance of 0. 4λ0 is chosen to construct the array. In order to decrease the coupling between close elements, the elements' positions are misaligned. Finally, the proposed DP mmWave array with a small size of 1. 39λ0 × 0. 42λ0 is achieved. A bandwidth of 24–28 GHz is realized for both polarizations. Within this band, the mutual couplings among adjacent elements are below −15 dB and the isolations between DP ports are above 20 dB. A wide 3 dB beam scanning range of ±60° for horizontal polarization radiation and ±50° for vertical polarization radiation is achieved. Within the beam scanning range, an acceptable less than −6.2 dB sidelobe level and a moderate below −15 dB cross-polarization level can be maintained. This compact wide-beam scanning DP mmWave array has the potential for future applications of mobile terminals.

Microbial Community and Urban Water Quality

Urbanization of China is substantial and growing, and water resources are crucial for both economic and social sustainable development. Unfortunately, the frequency and intensity of water contamination events are increasing at an unprecedented rate and often accompanied by increased pollutant loading due to human activities such as irreversible industrialization and urbanization. The impacts of human pollution are most evident and of greatest concern at the microbial level. The research of the Aquatic Ecohealth Group, Key Laboratory of Urban Environment and Health, Institute of Urban Environment, Chinese Academy of Sciences, has been focusing mainly on aquatic microorganisms in the urban environment, from drinking water and landscape water to waste water. Its projects fall into three categories: biomonitoring and bioassessment, microbial ecology and diversity, ecotoxicology and environmental microbiology. Its scientif ic topics include the aquatic ecological safety and microbial food web.
