The band energy structures of CeF2Cl and CeFCl2 crystals have been calculated using the projector augmented-wave (PAW) method and the hybrid exchange-correlation functional PBE0. The valence band top consists of 2p states of F and 3p states of Cl. An energy gap is observed between the 5d states of Ce in the bottom part of the conduction band of both crystals, forming two subbands, 5d1 and 5d2, with very different effective electron masses (2.49 m0 and 0.19 m0 for CeF2Cl and 5.95 m0 and 0.84 m0 for CeFCl2, respectively). The 4f states of Ce are placed within the forbidden band. The obtained values for the band gap of CeF2Cl and CeFCl2 crystals are 6 eV and 4.6 eV, respectively.
IMPLIKASI FIKIH PENGGUNAAN METODE HISAB WUJÛD AL-HILÂL PADA KALENDER MUHAMMADIYAH
Authors: Maskufa Maskufa 
Published: May 2024

Kalender Hijriyah Muhammadiyah disusun dengan menggunakan metode hisab wujûd al-hilâl tanpa membedakan fungsi kalender untuk ibadah dan muamalat atau administrasi. Tiadanya pembedaan fungsi kalender ini menjadikan kalender Muhammadiyah lebih menunjukkan kepastian dalam penetapan hari-hari besar keagamaan sehingga memberikan kemudahan dalam membuat perencanaan kegiatan yang bernuansa keagamaan. Meskipun demikian, masih beragamnya metode yang digunakan dalam penyusunan kalender yang ada di Indonesia menyebabkan penetapan hari-hari besar keagamaan khususnya bulan-bulan yang terkait dengan ibadah masih belum seragam. Perbedaan dalam penggunaan metode ini mempunyai implikasi fikih yang signifikan seperti puasa Ramadan, hari raya, puasa Arafah, kurban dan zakat. Tulisan ini akan membahas persoalan tersebut dengan menggunakan tiga pendekatan yaitu ilmu ushul fikih, ilmu astronomi, dan sosiologi.

Abstract
Muhammadiyah Islamic lunar calendar is composed on the methodological basis of the emergence of the Moon (wujud al-hilal). This method does not distinguish the function of calendar whether for worship, transaction or administrative objectives. The absence of such limit shows that the Muhammadiyah calendar system strives to put certainty in determining the dates of Islamic holidays so to make Muslims easy to prepare the events far before they are realized. However, unlike the Muhammadiyah, there are different methods of composing the Islamic lunar calendar amongst Islamic organizations in Indonesia. As a result, conflicts amongst Muslims often occur when determining the dates of Islamic worship and event. This, furthermore, has caused legal implication in Islamic law, such as in determining the beginning of the fasting month, the first day of idul fitri and the payment of zakat al-fitr, the fasting in the days of the hajj and the slaughtering of animals. This article will examines the issue of discrepancies in determining the beginning of the Islamic lunar calendar seen from the perspectives of Islamic legal methodology (usul al-fiqh), astronomy and sociology.

Research on the Attenuation Characteristics of Frequency Domain Parameters in Different Rock Medium
Authors: Liu Xiling , Liu Huini , Xiong Feng , Xie Qin , Zhong Yuchen , Hao Qi 
Published: May 2024

Abstract
This study examines the frequency attenuation characteristics of elastic waves in marble, granite, and red sandstone through laboratory tests and numerical simulations based on ABAQUS software on eight rock samples. The correlation between the distance of the decay of the peak frequency and the petrophysical and mechanical parameters is also analyzed. The results show that elastic waves undergo stepwise attenuation of their peak frequency during laboratory attenuation tests. This finding was confirmed by numerical simulations. As elastic waves propagate through a rock medium, the amplitude of the high-frequency peak area near the excitation frequency decreases rapidly, while the proportion of low-frequency signals increases. As the propagation continues, the signal spectrum is dominated by low-frequency components, resulting in a stepwise attenuation of the peak frequency. It has been observed that the step decay distance of the peak frequency of elastic waves varies with the degree of particle bonding, which can be used to characterize the attenuation properties of elastic waves in a medium.
Effect of ultrasound-guided injection of botulinum toxin type A into shoulder joint cavity on shoulder pain in poststroke patients: Study Protocol for a Randomized Controlled Trial
Authors: Zheng Peng , Zheng Manxu , Fan Tao 
Published: May 2024

Abstract

Background
Hemiplegic shoulder pain (HSP) is a common complication after stroke. It severely affects the recovery of upper limb motor function. Early shoulder pain in hemiplegic patients are mainly neuropathic caused by central nerve injury or neuroplasticity. Commonly used corticosteroid injections in the shoulder joint can reduce shoulder pain, however, the side effects also include soft tissue degeneration or increased tendon fragility, and the long-term effects remain controversial. Botulinum toxin injections are relatively new and are thought to block the transmission of pain receptors in the shoulder joint cavity, inhibit the production of neuropathogenic substances to reduce neurogenic inflammation. However, there is no conclusive evidence as to whether or not the amelioration of pain by botulinum toxin affects brain function. In previous studies of botulinum toxin versus glucocorticoids in the treatment of shoulder pain, there is a lack of observation of differences in changes in brain function. As the content of previous assessments of pain improvement was predominantly subjective, objective quantitative assessment indicators were lacking. Functional near-infrared imaging (fNIRS) can remedy this problem.
Methods
This study protocol was designed for a double-blind, randomized controlled clinical trial of patients with post-stroke HSP without biceps longus tenosynovitis or acromion bursitis. 78 patients will be randomly assigned to either the botulinum toxin type A or glucocorticoid group. At baseline, patients in each group will receive shoulder cavity injections of either botulinum toxin or glucocorticoids and will be followed for 1 and 4 weeks. The primary outcome is change in shoulder pain on the Visual Analog Scale (VAS). Secondary outcomes is the assessment of changes in oxyhemoglobin levels in the corresponding brain regions by fNIRS imaging, shoulder flexion, external rotation range of motion, upper extremity Fugl-Meyer, and modified Ashworth score.
Discussion
Ultrasound-guided botulinum toxin type A shoulder joint cavity injections may provide evidence of pain improvement in patients with HSP. The results of this trial are also help to analyse the correlation between changes in shoulder pain and changes in cerebral haemodynamics and shoulder joint motor function.

Abstract

In view of the severe problem of mine pressure behavior under the influence of mining stress superposition on both sides of the working face, this paper takes the isolated working face of Shanxi Yangquan H-N Coal Mine as the research object, and uses FLAC3D numerical simulation software to study the evolution of the plastic zone of the mining roadway in the isolated working face, the distribution of the second invariant field of the partial stress and the distribution of the third invariant field of the partial stress. The results show that there is a large-scale non-uniform failure in the roadway within 15 m of the advanced working face, and the plastic zone of the negative side and the floor appears through the phenomenon. The plastic zone at the roof extends to the positive side, and the shape is ' eagle beak '. The distribution pattern of J2 is basically consistent with the distribution pattern of plastic zone; According to the distribution pattern of J3, within 15 m from the working face, large compressive strain appears in the deep part of both sides of the roadway, and a certain range of tensile strain appears in the shallow part of the roadway. The J2 distribution of roof and floor of mining roadway is ' inverted trapezoid ' distribution, and both sides of roof and floor are more prone to large damage. The J3 distribution of floor of mining roadway is ' trapezoid ' distribution, both sides of floor are in compressive strain state, the middle part of roadway is in tensile strain state, and the J2 distribution of roadway side is ' inverted V ' distribution. With the closer to the working face, the vertex of ' inverted V ' is farther from the roadway, and the vertex value of ' inverted V ' is larger, that is, the greater the damage; the distribution of J3 in the side of the mining roadway is ' V-shaped '. On the positive side, only the coal in the middle of the coal pillar is in compressive strain, and the rest is tensile strain. On the negative side, only the shallow part of the roadway is in tensile strain, and the rest is compressive strain. According to the shape of plastic zone, J2 and J3 distribution, the roof roadway is reinforced and the angle of anchoring hole is adjusted. According to the observation results of surface displacement on site, the optimization of support parameters has a good effect on controlling the deformation of surrounding rock of mining roadway in island working face.

Abstract

Considered one of the most consumed foods in the world, milk has many nutritional properties healthily to human. The toxic elements in milk can come from environmental sources such as the area where livestock are confined, as well as food and water. In addition, milk can be contaminated during and after ordering, in the industrialization process or, during transport and packaging. Whey is often discarded in the manufacture of milk, however some applications of this by-product can be useful, and among the advantages is the reduction of waste generation, thus becoming an environmentally correct action. In this work, an FIA-FAAS system was proposed using activated carbon fibers (ACF) modified with albumin forming Restricted Access Material (ACF-RAM) and using this material as an adsorbent in SPE, for determination of cadmium in whey. The abbreviation adopted for this method was FIA-SPE-ACF-RAM-FAAS. The RAM possibility the directed introduction of the whey samples to the system without any prior treatment because only ions could be adsorbed into ACS, the bigger molecules, e.g. proteins, were discarded to waste during the process. The FIA system was optimized by chemometric tools such as Factorial Design and Doehlert Matrix. The Limit of Detection was 0.24 µg L-1 and the Limit of Quantification was 0.81 µg L-1. The method was applied to a whey sample, the precision checked through Relative Standard Deviation was always less than 5.0 %. The accuracy was verified through the spiked sample and recovery were between 95% and 105%.

Abstract

Climate change is expected to increase the frequency and severity of climate extremes, which will negatively impact crop production. As one of the main food and feed crops, maize is also vulnerable to extreme climate events. In order to accurately and comprehensively assess the future climate risk to maize, it is urgent to project and evaluate the stress of extreme climate related maize production under future climate scenarios. In this study, we comprehensively evaluated the spatio-temporal changes in the frequency and intensity of six extreme climate indices (ECIs) across China’s maize harvest region by using a multi-model ensemble method, and examined the capability of the Coupled Model Intercomparison Project Phase 6 (CMIP6) to capture these variations. We found that the Independence Weight Mean (IWM) ensemble results calculated by multiple Global Change Models (GCMs) with bias correction could better reproduce each ECI. The results indicated that heat stress for maize showed consistent increase trends under four future climate scenarios in the 21st century. The intensity and frequency of the three extreme temperature indices in 2080s were significantly higher than these in 2040s, and in the high emission scenario were significantly higher than these in the low emission scenario. The three extreme precipitation indices changed slightly in the future, but the spatial changes were relatively prominent. Overall, the temporal characteristics and trends of extreme temperature events were consistent, while the spatial heterogeneity of extreme precipitation events was more significant.

Published: May 2024

Abstract

The dynamic caustics system combined with numerical simulation is used to study the effect of the slit in the borehole on the blasting effect. The result show that: slit blasting of the borehole has a significant directional fracture effect when compared with ordinary blasting, the length of cracks in the slit direction is significantly larger than that of ordinary blasting, and the length and number of cracks in the non-slit direction are significantly smaller than that of ordinary blasting. The slit in the borehole wall causes the blast energy to be released mainly in the slit direction and suppressed in the non-slit direction. Crack inhibition zone exists at the root of slit in the borehole wall. Once blasting produced the direction cracks in the slit direction, the surroundings of the blast hole wall will not produce cracks. Slit blasting can inhibit cracks near the slits, so as to achieve the purpose of controlling the direction of rock fracture. As the slit length increased, the major crack propagation length of the slits decreased before increasing. When the slit length increased to 5mm (diameter to length ratio of 1.2), the crack propagation length was the largest, then the slit length continued to increase, the crack extension length did not change much. With the increase of the slit length, the peak value of the slit main crack propagation stress intensity factor and the peak value of the velocity show the trend of decreasing and then increasing, and the two peak values are the lowest when the slit length is 3 mm. The horizontal incident tensile wave reflected by rock mass defects and blasthole unloading waves increase the stress intensity factor and crack propagation rate, promoting crack propagation. Considering the blasting effect, the cost and time of drilling slits, it is more appropriate to choose a slit length of 0.5mm (diameter to length ratio λ is 12). The research results provide a certain significance of guidance for the slit blasting of the borehole wall in practical engineering.

Abstract

Background: The primary immunological readout for clinical vaccine trials of the Plasmodium falciparum (Pf) pre-erythrocytic malaria vaccine, R21/MatrixM, is total IgG antibody specific to the central four amino acid (NANP) repeat region of the circumsporozoite protein (CSP). A multiplexed Meso Scale Discovery (MSD) assay, which includes the NANP repeat region of CSP, was developed and validated.
Methods: Here we describe the validation of a multiplexed MSD assay to measure serum or plasma antibody binding to four antigens: six repeats of the NANP repeat region of P. falciparum (Pf) CSP, the C-terminus (C-term) region of CSP, full length R21 vaccine construct, and hepatitis B surface antigen (HBsAg). Initial assay optimisation, which included validation of the HBsAg international standard, was performed by MSD. Further validation performed in Oxford covered intra and inter-assay, and inter-operator variability, accuracy of QC and standard curve samples, and included bridging between the singleplex ELISA used in previous R21/MM studies, and this multiplexed assay.
Results: The multiplexed MSD assay was shown to be a robust and specific assay with a broad dynamic range. We report a strong linear relationship between NANP6 IgG as measured by the singleplex ELISA and the multiplexed assay.
Conclusions: This multiplexed MSD assay can be used to measure antibodies specific to the CSP NANP repeat region, CSP C-term region, full length R21 vaccine construct, and HBsAg. This assay can be used to determine humoral immune responses elicited by CSP-containing Pf malaria vaccines.
