Published: February 2025

Abstract
Nowadays modern apparel industry encounters numerous challenges, including the dynamic nature of the market and the increasing customer demand for product variety. This drives fashion industries to diversify their product range, intensifying competition and leading to the production of a wide range of products in a single factory. Hence, implementing a systematic method and/or model to ascertain optimal product mix combinations within a garment factory becomes pivotal for informed decision-making. The current research aims to formulate a model to manage the available resources and improve overall operational efficiency through optimal product mix and production scheduling. The case study took place at CBA Garments Factory PLC in Ethiopia, which aimed to produce multiple garments but ultimately manufactured only one product at a time. The research employed quantitative research through analyzing data, general sewing data system, utilizing sequencing and scheduling approaches, and employing simple integer linear programming modeling tools. Based on the result, the newly developed optimized model enabled the case company to produce an average of four product types to fulfil multiple orders and increase resource utilization from 19.6% to an average of 73%.
Unlocking chemistry calculation proficiency: uncovering student struggles and flipped classroom benefits
Authors: Rusek Martin 
Published: February 2025

Abstract
This study investigated the challenges first-year bachelor teacher students (N = 24 in experimental and 36 in the control group) face in basic chemistry calculations, a critical aspect of chemistry education. This study investigated the effectiveness of a flipped-classroom model in a Chemistry Calculations course for pre-service teachers during the pandemic-induced shift to online education. A control group, which experienced traditional in-person instruction, and an experimental group, which experienced the flipped-classroom model, were compared. The students’ progress was measured through pre- and post-tests covering five types of chemical calculations, and interviews with 12 students provided additional insights. Results indicated that while students generally handle calculations involving composition of solutions well, they struggle with pH calculations, mixing equations, and balancing chemical equations. The study identified lack of attention to these topics in some secondary schools and students’ difficulties with mathematical concepts as key factors in these challenges. This research aims to guide undergraduate instructors in optimising course content to address these issues, thereby improving students’ performance, and reducing dropout rates. It highlights the need for further investigation into the teaching of chemistry calculations at the secondary level.
Mass rearing protocol and density trials of Lilioceris egena (Coleoptera: Chrysomelidae), a biological control agent of air potato
Authors: Murray Rosemary B. , Hahn Philip G. , Menocal Octavio 
Published: February 2025

Abstract

Lilioceris egena (Weise) (Coleoptera: Chrysomelidae) is an approved classical biological control agent that feeds on the aerial reproductive structures (i.e., bulbils) of the invasive air potato vine in Florida. The Florida Department of Agriculture and Consumer Services, Division of Plant Industry, has mass-produced and released over 100,000 beetles since 2021. Mass rearing can be challenging for highly specialized herbivores like L. egena. Therefore, we present a detailed protocol to mass rear L. egena under laboratory settings. This protocol ensures consistent production of approximately 675 beetles per month/colony for research and field applications while maintaining efficiency and affordability. Additionally, we determined how the number of mating pairs and the condition of air potato bulbils (whole or bisected) used in the mass rearing system influenced the number of adults produced. Results showed that 17 mating pairs per bulbil (of approximately 150 g) was an optimal beetle density to maximize beetle production and maintain a healthy colony. The condition of bulbils utilized did not influence the number of adults produced. This protocol can be adopted by integrated pest management (IPM) and master gardener programs, universities, and regulatory agencies in other southeastern states currently facing air potato infestations.

Authors: Zhu Yeqing , Huang Xiaojun , Yu Tianxiang , Liu Kun , Zhang Meng 
Published: February 2025

Abstract
The fly ash (FA) is one of the large amount of solid wastes stored in China. Because of its low price, large specific surface area, and surface electronegativity, reasonable modification can turn FA into treasure, prepared as an adsorption material with good adsorption performance. In this article, the industrial solid waste FA is used as raw material, and the FA-based sodium aluminosilicate was synthesized by a one-step hydrothermal alkali dissolution method and characterized by X-ray fluorescence, X-ray diffraction, scanning electron microscopy, Fourier transform infrared, Brunauer Emmett Teller, and other test methods. The results show that (1) aluminum silicate sodium hydrate can be synthesized by low-temperature method under atmospheric pressure to form P-type zeolite and calcite structure. (2) Alkali concentration, temperature, and reaction time affect the structure of aluminosilicate sodium hydrate. With the increase of alkali concentration, temperature, and reaction time, the product changes from P-type zeolite to calite structure. (3) The optimal synthesis condition of FA for sodium aluminosilicate hydrate is as follows: the concentration of NaOH solution is 4 mol·L−1, the dissolution temperature is 80°C, the reaction time is 21 h, and the specific surface area is 60.54 m2·g−1.

Published: February 2025

Abstract

Objectives
To investigate the effect of orally administered cytidine-5′-diphosphocholine (citicholine) (50,100,200 mg/kg), α-tocopherol (Vit E; 25 mg/kg), caffeine (10 mg/kg), L-dopa (25 mg/kg) or the combination of Vit E, caffeine with citicholine (100 mg/kg) on nigrostriatal neuronal damage induced in the mice brain by subcutaneous (s.c.) rotenone.

Methods
Swiss male mice received rotenone (1.5 mg/kg, s.c, three times per week) alone or with other drugs for 2 weeks. Mice were evaluated for brain malondialdehyde (MDA), reduced glutathione (GSH), and nitric oxide (NO), paraoxonase-1 (PON-1), acetylcholinesterase (ACHE), interlukin-1beta (IL-1β), nuclear factor kappa B (NF-κB) and monocyte chemoattractant protein (MCP-1). Histopathologic examination was also done.

Results
Cticholine co-treatment at 50, 100 or 200 mg/kg significantly decreased brain MDA and increased PON-1 activity in a dose-dependent manner. When given at 200 mg/kg, it also significantly decreased NO production, while at 100 and 200 mg/kg significantly increased GSH brain. MCP-1 significantly decreased upon treatment with 100 or 200 mg/kg of citicholine. IL-1 β and NF-κB significantly decreased and AChE significantly increased by 200 mg/kg citicholine. Oxidative stress and inflammatory biomarkers also showed favorable changes after Vit E, caffeine or L-dopa. However, the combination of Vit E and/or caffeine with 100 mg/kg citicholine was not superior to that of only citicholine at 100 or 200 mg/kg.

Conclusions
Citicholine is neuroprotective in acute rotenone nigrostriatal degeneration via antioxidant and anti-inflammatory properties. It is suggested that citicholine may have a role in treatment of Parkinson’s disease by decreasing neuro-inflammation and oxidative stress, preventing the development of neuronal damage.

Abstract

Aim
The aim of this study is to determine the effect of vitamin D replacement therapy on sleep habits in restless legs syndrome (RLS) patients with vitamin D deficiency.

Methods
The study was conducted between September 1, 2018, and September 1, 2019, at the Pediatrics outpatient clinic of Bezmialem Vakif University. 46 cases with RLS and 43 healthy controls between these dates were included in the study. The Children’s Sleep Habits Questionnare was filled out retrospectively by parents.

Results
While vitamin D supplementation was given to 20 children with RLS who were found to have vitamin D deficiency, the 26 patients without vitamin D deficiency did not receive supplementation. There was no significant difference between the treatment groups in terms of gender, age, and pre-treatment sleep habits. Compared to the pre-treatment period, post-treatment bedtime resistance, sleep onset delay, sleep anxiety, parasomnias, daytime sleepiness, and CSHQ total score were significantly improved in RLS cases with vitamin D deficiency. There were no significant differences in RLS patients without vitamin D supplementation. Other comparisons also showed no difference between groups.

Conclusion
There was no difference between the sleep habits of RLS cases with and without vitamin D deficiency. Sleep habits improved positively after vitamin D supplementation in patients with vitamin D deficiency compared to the pre-treatment period. There was no difference in the sleeping habits of RLS patients without vitamin D deficiency during the same period. Vitamin D supplementation can improve sleep habits in patients with RLS.

-dimensional modified Zakharov–Kuznetsov (mZK) partial differential equation is of importance as a model for phenomena in various physical fields such as discrete electrical lattices, electrical waves in cold plasmas, nonlinear optical waves, deep ocean-waves, and the propagation of solitary gravity waves. In this study, the main objective is to give a detailed analysis of exact traveling wave solutions of the mZK equation with truncated M-fractional spatial–temporal partial derivatives. Using an appropriate traveling wave transformation and the homogeneous balance rule, the mZK equation is converted into a corresponding ordinary differential equation (ODE). The

-expansion and Sardar subequation methods are then used to derive exact solutions of the ODE in the form of functions such as hyperbolic, trigonometric, and special generalized hyperbolic and trigonometric functions. The two methods give some novel solutions of the proposed model and are presented here for the first time. The fractional-order effects are studied through numerical simulations, including three-dimensional (3D), two-dimensional (2D), and contour plots. These numerical simulations clearly show physical interpretations of selected solutions. In particular, the generalized hyperbolic and trigonometric function solutions that have been derived by the Sardar subequation method are important as they provide examples of exact traveling wave solutions of various physical types. Furthermore, the results include examples of bifurcations and chaotic behaviors of the model through 2D and 3D plots when parameter values are varied. Finally, the methods of solution described in this study are reliable, powerful, and efficient and can be recommended to obtain traveling wave solutions of other nonlinear partial differential equations with truncated M-fractional derivatives.
Optical and laser damage resistance: Role of periodic cylindrical surfaces
Authors: Li Yuan , Su Junhong 
Published: February 2025

Abstract
Traditional laser thin film optical components are specially designed layered structures made of two or more materials. However, as the number of layers increases, the anti-laser damage ability of the optical elements is significantly reduced. In this study, a single-layer structured surface is designed to have better optical transmittance than its homogeneous substrate. It also shows potential advantages in laser damage resistance applications. The transmittance and laser damage morphology of periodic cylindrical surfaces and their uniform substrates using a combination of experimental and simulation methods are examined. According to ISO21254, the laser-induced damage threshold (LIDT) of the structured surface and the uniform substrate were measured on a 1-on-1 irradiation of a 1,064 nm laser with a pulse width of 10 ns. The measured LIDT values were (15.3 ± 1.15) J/cm2 for the structured surface and (15.2 ± 1.09) J/cm2 for the uniform substrate. The damaged morphology of the structured surface was analyzed using a polarizing microscope to study its periodic distribution. Additionally, the electric field distribution on the surface of the structure and its uniform substrate was simulated using the finite element method. The results indicate that the damage characteristics of the structured surface are influenced by the surface structure, and the presence of the structure influences the energy distribution of laser deposition. This study serves as a valuable reference for further research into the laser damage mechanism of structured surfaces.
With Agrivoltaics Cooperatives towards Electricity Self-Sufficient Villages in Germany?
Authors: Bauknecht Martin 
Published: February 2025

Abstract
This paper aims to examine a new business opportunity for energy cooperatives: Integration of agrivoltaics and energy sharing allows an electricity selfsufficient village. The development of energy cooperatives presents a viable path toward decentralized and sustainable energy systems. Agrivoltaics, which combines agricultural with solar energy production, emerges as a pivotal strategy for establishing electricity self-sufficient villages. Solar Package I law provides the foundational regulatory and financial framework to promote agrivoltaics installations, enhancing both food and electricity production on the same land. Building on this, Solar Package II is crucial for facilitating energy sharing within energy cooperatives, enabling communities to trade and utilize locally produced energy efficiently. A robust business model for electricity self-sufficient villages has been developed, focusing on integrating renewable energy sources, implementing advanced energy storage solutions, and fostering local energy markets. This model emphasizes local power generation, significantly reducing the need for extensive and costly grid infrastructure investments across Germany. By empowering local communities through energy cooperatives and leveraging innovative solutions like agrivoltaics and energy sharing, this approach not only enhances energy security and sustainability but also stimulates local economies and promotes community resilience.
MEDiCINe: Motion Correction for Neural Electrophysiology Recordings
Authors: Watters Nicholas , Buccino Alessio , Jazayeri Mehrdad 
Published: February 2025

Electrophysiology recordings from the brain using laminar multielectrode arrays allow researchers to measure the activity of many neurons simultaneously. However, laminar microelectrode arrays move relative to their surrounding neural tissue for a variety of reasons, such as pulsation, changes in intracranial pressure, and decompression of neural tissue after insertion. Inferring and correcting for this motion stabilizes the recording and is critical to identify and track single neurons across time. Such motion correction is a preprocessing step of standard spike sorting methods. However, estimating motion robustly and accurately in electrophysiology recordings is challenging due to the stochasticity of the neural data. To tackle this problem, we introduceMEDiCINe(MotionEstimation byDistributionalContrastiveInference forNeurophysiology), a novel motion estimation method. We show that MEDiCINe outperforms existing motion estimation methods on an extensive suite of simulated neurophysiology recordings and leads to more accurate spike sorting. We also show that MEDiCINe accurately estimates the motion in primate and rodent electrophysiology recordings with a variety of motion and stability statistics. We open-source MEDiCINe, usage instructions, examples integrating MEDiCINe with common tools for spike-sorting, and data and code for reproducing our results. This open software will enable other researchers to use MEDiCINe to improve spike sorting results and get the most out of their electrophysiology datasets.Significance StatementRecent advances in high-density microelectrode arrays such as Neuropixels have allowed neurophysiologists to record from hundreds of neurons simultaneously. Such data scale necessitates automatic isolation and tracking of individual neurons throughout a recording session, a process called “spike sorting”. One challenge for automated spike sorting algorithms is relative motion between the electrodes and the brain, which must be corrected to stabilize the recording. We introduce a method for estimating such motion in neural recordings. Our method outperforms existing motion estimation methods and produces more accurate spike sorting on a benchmark of simulated datasets with known ground-truth motion. Our method also performs well on primate neurophysiology datasets. We open-source our method and instructions for integrating it into common spike sorting pipelines.
Kv4.2 regulates basal synaptic strength by inhibiting R-type calcium channels in the hippocampus

Published: February 2025

Kv4.2 subunits, which mediate transient A-type K+current, are crucial in regulating neuronal excitability and synaptic responses within the hippocampus. While their contribution to activity-dependent regulation of synaptic response is well-established, the impact of Kv4.2 on basal synaptic strength remains elusive. To address this gap, we introduced Kv4.2-specific antibody (anti-Kv4.2) into hippocampal neurons of mouse of both sexes to selectively inhibit postsynaptic Kv4.2, enabling direct examination of its impact on excitatory postsynaptic potentials (EPSPs) and currents (EPSCs) during basal synaptic activity. Our results demonstrated that blocking Kv4.2 significantly enhanced the amplitude of EPSPs. This amplification was proportional to the increase in the amplitude of EPSCs, which, in turn, correlated with the expression level of Kv4.2 in dendritic regions of the hippocampus. Furthermore, the anti-Kv4.2-induced increase in EPSC amplitude was associated with a decrease in the failure rate of EPSCs evoked by minimal stimulation, suggesting that blocking Kv4.2 facilitates the recruitment of AMPA receptors to both silent and functional synapses to enhance synaptic efficacy. The anti-Kv4.2-induced synaptic potentiation was effectively abolished by intracellular 10 mM BAPTA or by blocking R-type calcium channels (RTCCs) and downstream signaling molecules, including protein kinase A and C. Importantly, Kv4.2 inhibition did not occlude further synaptic potentiation induced by high frequency stimulation, suggesting that anti-Kv4.2 induced synaptic strengthening involves unique mechanisms that are distinct from long-term potentiation pathways. Taken together, these findings underscore the essential role of Kv4.2 in the regulation of basal synaptic strength, which is mediated by inhibition of RTCCs.Significance StatementSynaptic transmission is mediated primarily by AMPA receptors (AMPARs) and there has been considerable interest in elucidating the mechanisms underlying their recruitment during activity-dependent synaptic strengthening. However, the mechanism by which basal synaptic strength is regulated remains elusive. Here, we show that blocking postsynaptic Kv4.2 enhances AMPAR-mediated currents in hippocampal neurons, and that this enhancement is mediated by the signaling mechanisms involving R-type Ca2+channels, protein kinases A and C. Importantly, Kv4.2 inhibition did not occlude activity-dependent synaptic potentiation, suggesting its specific influence in regulating synaptic AMPARs under basal conditions. Thus, our study highlights the critical function of Kv4.2 in regulating Ca2+signaling at subthreshold potentials, thereby regulating basal synaptic strength.
