Intermediate surgical outcome in patients suffering poor-grade aneurysmal subarachnoid hemorrhage. A single center experience

Abstract Background It is known that patients suffering poor-grade aneurysmal subarachnoid hemorrhage (aSAH) have a dismal prognosis. The importance of early intervention is well established in the pertinent literature. Our aim was to assess the functional outcome and overall survival of these patients undergoing surgical clipping. Material and methods In the current retrospective study we included all consecutive poor-grade patients after spontaneous SAH who presented at our institution over an eight-year period. All participants suffering SAH underwent brain CT angiography (CTA) to identify the source of hemorrhage. We assessed the severity of hemorrhage according to the Fisher grade classification scale. All patients were surgically treated. The functional outcome was evaluated six months after the onset with the Glasgow Outcome Scale. Finally, we performed logistic and Cox regression analyses to identify potential prognostic risk factors. Results Our study included twenty-three patients with a mean age of 53 years. Five (22%) patients presented with Hunt and Hess grade IV, and eighteen (78%) with grade V. The mean follow-up was 15.8 months, while the overall mortality rate was 48%. The six-month functional outcome was favorable in 6 (26%) patients. The vast majority of our patients died between the 15th and the 60th post-ictal days. We did not identify any statistically significant prognostic factors related to the patient’s outcome and/or survival. Conclusions Poor-grade aSAH patients may have a favorable outcome with proper surgical management. Large-scale studies are necessary for accurately outlining the prognosis of this entity, and identifying parameters that could be predictive of outcome.
Internal Structure and Hydrothermal Fluid Circulation of Parícutin Volcano, Mexico: Insights Gained From Near‐Surface Geophysics

Numerous investigations of Parícutin volcano have been made since its formation during 1943–1952, but none has utilized geophysical techniques until now. This report summarizes the results of near‐surface geophysical surveys conducted during 2017–2019, involving self‐potential, ground‐temperature measurements, and a 3D resistivity model of the scoria cone. Interpretation of the integrated data enabled the definition of the geometry of the eruption's feeder dyke and a better understanding of the near‐surface spatter facies. These geophysical data also better characterized the buried morphology of a horseshoe‐shaped crater produced by a cone collapse early in the eruption, as well as the contact between lava flows and overlying pyroclastic fallout deposits. Moreover, the measured conductivities detected several meter‐scale zones of convective hydrothermal fluid circulation within the cone. Collectively, the data of this study demonstrate a powerful approach to discern the relationship between the internal structure of a monogenetic cone and its associated hydrothermal system.
Assessing Determinants of Farmer’s Participation in Sugarcane Contract Farming in Indonesia

The integrated value chain is a prerequisite for the successful industrialization of the agricultural sector. Contract farming (CF) is a useful instrument to integrate the agricultural value chain in developing countries such as Indonesia. The purpose of this study was to identify the determinants of farmer participation in sugarcane contract farming. The data utilized in this study was obtained from the Indonesian Plantation Farm Household Survey 2014 for Sugarcane. The data consists of 8.831 farmers distributed in 8 provinces. Logistic regression was used to estimate the determinants of farmer participation in sugarcane CF. The result shows that age, education, and type of cultivated land negatively affect farmer participation in sugarcane CF. Meanwhile, land tenure, cultivation area, cropping system, certified seed, membership in a cooperative, access to extension services, and membership in farmer’s association positively affect farmer participation in sugarcane CF. The policy implication for increasing farmer participation in CF is to intensify the information of CF to the farmer with a large cultivation area. Since these farmers tend to participate in CF to anticipate marketing risks.
Cold and Dense Plasma Sheet Caused by Solar Wind Entry: Direct Evidence

We present a coordinated observation with the Magnetospheric Multiscale (MMS) mission, located in the Earth’s magnetotail plasma sheet, and the Acceleration, Reconnection, Turbulence, and Electrodynamics of the Moon’s Interaction with the Sun (ARTEMIS) mission, located in the solar wind, in order to understand the formation mechanism of the cold and dense plasma sheet (CDPS). MMS detected two CDPSs composed of two ion populations with different energies, where the energy of the cold ion population is the same as that of the solar wind measured by ARTEMIS. This feature directly indicates that the CDPSs are caused by the solar wind entry. In addition, He+ was observed in the CDPSs. The plasma density in these two CDPSs are ~1.8 cm−3 and ~10 cm−3, respectively, roughly 4–30 times the average value of a plasma sheet. We performed a cross-correlation analysis on the ion density of the CDPS and the solar wind, and we found that it takes 3.7–5.9 h for the solar wind to enter the plasma sheet. Such a coordinated observation confirms the previous speculation based on single-spacecraft measurements.
PETTLEP imagery and tennis service performance: an applied investigation

Abstract Tennis is one of the most popular and widely played sports enjoyed by players of different age groups and genders as a profession as well as a mode of recreation. A novel method, PETTLEP imagery combines both conventional and non-conventional style of training of an athlete and improves one’s performance. This study aimed to analyze the tennis service performance of junior tennis players based on PETTLEP imagery training. Forty-four junior male tennis players (M age=13.22 years, SD=0.42) were selected for the study. The investigator handed over the MIQ-R questionnaire to all the participants in which they scored 16 and above points as per previous research. The participants were equally divided (n=11) into three experimental groups (E1, E2, and E3) and a control group. The service performance outcomes of all the players were compared before and after a training session. The three experimental groups were assigned with service-specific training, service-specific training combined with PETTLEP imagery training, and PETTLEP imagery training alone, respectively, for three days per week for 12 weeks. They were tested on their service accuracy based on the International tennis number (ITN) manual on-court assessment test. The data were assessed for normality and analyzed using non-parametric methods to reveal main effects (each training method alone) as well as to calculate the combined effect of PETTLEP and service-specific training. Certain significant improvements in tennis service were observed with service-specific training alone. Though it marginally outperformed the PETTLEP imagery method, the most improved services were observed with both PETTLEP and service-specific training utilized together. This implies an additive effect when both methods are used together.
Real-Time Traffic Flow Forecasting via a Novel Method Combining Periodic-Trend Decomposition

Accurate and timely traffic flow forecasting is a critical task of the intelligent transportation system (ITS). The predicted results offer the necessary information to support the decisions of administrators and travelers. To investigate trend and periodic characteristics of traffic flow and develop a more accurate prediction, a novel method combining periodic-trend decomposition (PTD) is proposed in this paper. This hybrid method is based on the principle of “decomposition first and forecasting last”. The well-designed PTD approach can decompose the original traffic flow into three components, including trend, periodicity, and remainder. The periodicity is a strict period function and predicted by cycling, while the trend and remainder are predicted by modelling. To demonstrate the universal applicability of the hybrid method, four prevalent models are separately combined with PTD to establish hybrid models. Traffic volume data are collected from the Minnesota Department of Transportation (Mn/DOT) and used to conduct experiments. Empirical results show that the mean absolute error (MAE), mean absolute percentage error (MAPE), and mean square error (MSE) of hybrid models are averagely reduced by 17%, 17%, and 29% more than individual models, respectively. In addition, the hybrid method is robust for a multi-step prediction. These findings indicate that the proposed method combining PTD is promising for traffic flow forecasting.
The role of RIG-I, AIM2 and IFI16 receptors for viral RNA and DNA in the pathogenesis of spontaneous and early missed miscarria

Aim To identify the features of the expression of mRNA of intracellular RIG-I, IFI16 and AIM2 receptors for viral RNA and DNA, and their signaling pathway proteins in the decidual tissue of patients with spontaneous and early missed miscarriages. Material and methods The study comprised 68 patients with sporadic miscarriages, including 34 women with missed and 34 with spontaneous miscarriages at 6 to10 weeks of gestation. The control group included 57 patients who underwent surgical termination of pregnancy at the same gestational age. Patients with severe non-obstetric comorbidities, antiphospholipid syndrome, endocrine causes of miscarriage, and confirmed fetal chromosomal abnormalities were excluded from the study. Decidual tissues were collected by uterine curettage. Expression of RIG-I, IFI16 and AIM2 mRNA and their signaling pathway proteins (ASC, TBK1, STING, caspase-1, interleukin-1β) was analyzed using quantitative polymerase chain reaction. Results Patients with missed miscarriages had a seven-fold increase in the expression of decidual AIM2 mRNA protein detecting intracellular viral and Listeria’s DNA. This elevation was accompanied by an increase in the caspase-1 and IL-1β mRNA expression resulting in the initiation of an inflammatory response and pyroptotic cell death. Patients with missed miscarriages did not have significant changes in the expression of RIG-I and IFI16 mRNA, and their signaling pathway proteins. No changes in AIM2, RIG-I, and IFI16 mRNA expression and their signaling pathway proteins were observed in patients with spontaneous miscarriage. Conclusion Patients with missed miscarriages have an increased decidual expression of the AIM2 receptor for viral and Listeria’s DNA. This increase is accompanied by an increase in the caspase-1 and IL-1β mRNA expression, leading to the initiation of a pro-inflammatory response and cell death.
Urbanization versus other land use: Diverging effects on dragonfly communities in Germany

Land use change, such as urbanization and intensification of agricultural practices, poses major threats for biodiversity. We examined whether the composition of freshwater species differs between landscapes dominated by urban, agricultural or more natural structures in a region with a long history of landscape transformation. We determined the differences and characteristics of the dragonfly fauna in relation to major land use categories. We particularly focused on urban land use, as it generally induces a high level of landscape transformation.
β-Glucan and Parasites

Summary Immunosuppression caused by parasitic infections represents the foremost way by which the parasites overcome or escape the host’s immune response. Glucan is a well-established natural immunomodulator with the ability to significantly improve immune system, from innate immunity to both branches of specific immunity. Our review is focused on the possible role of glucan’s action in antiparasite therapies and vaccine strategies. We concluded that the established action of glucan opens a new window in treatment and protection against parasitic infections.
TRFLP analysis for revealing the diversity of rice phyllosphere bacteria

Wiraswati SM, Wahyudi AT, Rusmana I, Nawangsih AA. 2018. TRFLP analysis for revealing the diversity of rice phyllosphere bacteria. Biodiversitas 19: 1743-1749. Phyllosphere environment of rice plant is usually inhabited by diverse bacteria which mostly contribute beneficial effects to the plant fitness. TRFLP method is a rapid and straightforward method to determine the bacterial diversity of many environments, including rice phyllosphere environment. This study aimed to analyze rice phyllosphere bacterial diversity of healthy rice plant cultivar Ciherang obtained from Sukabumi, Jasinga, and Situgede. The bacterial genomes were amplified and digested with two restriction enzymes, i.e., MspI and BstUI. The bacterial diversity (H’ index) and evenness (E index) were calculated from the peak value. From TRFs analysis, Betaproteobacteria and Pseudomonadales were dominantly found in nearly all samples with different relative abundance. In addition, Alphaproteobacteria and Gammaproteobacteria were also dominant in the several samples. The unique bacteria groups were inhabited in the sample from specific regions with certain growth phase. This finding informs us that the geographical factors might be more influent than the growth phase factor. Furthermore, the bacterial diversity and evenness of the metagenomic approach are higher than cultivation-dependent approach.
Quality Differentiation and Optimal Pricing Strategy in Multi-sided Markets

This paper analyzes the generalized quality differentiation model in multi-sided markets with positive externalities, which leads to new insights into the optimal pricing structure of the firm. We find that quality differentiation for users on one side leads to a decrease in the price charged to users on the other side due to cross-subsidization, thereby affecting the pricing structure of multi-sided firms. In addition, quality differentiation affects the strategic relationships among the choice variables for the platform, so that the platform strategically uses quality differentiation to raise its profits.
Planning Grasps With Suction Cups and Parallel Grippers Using Superimposed Segmentation of Object Meshes

This article develops model-based grasp planning algorithms. It focuses on industrial end-effectors like grippers and suction cups, and plans grasp configurations considering computer aided design (CAD) models of target objects. The developed algorithms can stably find many high-quality grasps, with satisfying precision and little dependency on the quality of CAD models. The undergoing core technique is superimposed segmentation, which preprocesses a mesh model by peeling it into superimposed facets. The algorithms use the facets to locate contacts and synthesize grasp poses for popular industrial end-effectors. Several tunable parameters are prepared to adapt the algorithms to meet various requirements. The experimental section studies the influence of the tunable parameters and analyzes the cost, precision, and robustness of the proposed algorithms and their planned grasps, with both simulations and real-world systems. Besides, the proposed algorithms are applicable to mesh models reconstructed from point clouds obtained by depth sensors. Some experiments and analysis are also carried out to study and demonstrate the ability.
Basolateral localization of MMP14 drives apicobasal polarity change during EMT independently of its catalytic activity

The transmembrane Matrix Metalloproteinase MMP14/MT1-MMP is known to promote cell migration by cleavage of the extracellular matrix. To initiate migration, epithelial cells need to gain mesenchymal attributes. They reduce cell-cell junctions and apicobasal polarity and gain migratory capabilities. This process is named epithelial-mesenchymal transition (EMT). MMP14’s implication in EMT is still ill-defined. We used chick neural crest (NC) cells as a model to explore the function of MMP14 in physiological EMT. Our results show that MMP14 is expressed by chick NC cells. However, it is its subcellular localization, rather than its expression, that correlates with EMT. MMP14 is first apical and switches to basolateral domains during EMT. Loss of function and rescue experiments show that MMP14 is involved in EMT independently of its catalytic activity. It lies downstream of pro-EMT genes and upstream of cell polarity. We found that basolateral localization of MMP14 is required and sufficient to induce polarity change in NC cells and neuroepithelial cells, respectively. These effects on polarity occur without impact on cell-cell adhesion or the extracellular matrix. Overall, our data points to a new function of MMP14 in EMT that will need to be further explored in other systems such as cancer cells.
Visual Captions: Augmenting Verbal Communication with On-the-fly Visuals

Video conferencing solutions like Zoom, Google Meet, and Microsoft Teams are becoming increasingly popular for facilitating conversations, and recent advancements such as live captioning help people better understand each other. We believe that the addition of visuals based on the context of conversations could further improve comprehension of complex or unfamiliar concepts. To explore the potential of such capabilities, we conducted a formative study through remote interviews (N=10) and crowdsourced a dataset of over 1500 sentence-visual pairs across a wide range of contexts. These insights informed Visual Captions, a real-time system that integrates with a video conferencing platform to enrich verbal communication. Visual Captions leverages a fine-tuned large language model to proactively suggest relevant visuals in open-vocabulary conversations. We present findings from a lab study (N=26) and an in-the-wild case study (N=10), demonstrating how Visual Captions can help improve communication through visual augmentation in various scenarios.
OPTIMAL SOLUTION OF FIXED COST TRANSPORTATION PROBLEMS BY APPROXIMATING STAIRCASE METHOD

The fixed charge is the main issue facing by many of the production and transportation systems. It is posing real difficulties in the solving process since it does not depend on the number of units transported in that particular route. Even though the mathematical model has been framed and many of the researchers were done their research, very few were succeed to get the optimal solution. Those methods are effective when the sources and destinations are less in numbers and it is still difficult to get the optimal solution when the number of sources and destinations were increasing. We proposed a method in this paper to solve fixed cost transportation problems based on the linear approximation. It is very easy to understand and not posing any difficulties in the solving process. Using this method we can get a solution which is optimal for the problem in the finite number of steps. Proposed method is effective even though the sources and destinations are large in numbers.

Disclosure Tone Management and Labor Unions

By analyzing the influence of labor unions on the narrative content of corporate disclosures, we provide empirical evidence that managers deflate the tone of earnings press releases in order to convey to unions a less optimistic image of firm financial performance. We find that the tone of the qualitative information in earnings press releases is significantly less optimistic as the degree of unionization increases, and particularly when financial performance is strong. The results of quasi-natural experiments suggest that labor unions causally affect the use of tone deflation, and the deflation is stronger during labor negotiations. Our findings also indicate that labor unions lead to a significant weakening of the signaling value of the tone of earnings press releases in predicting future performance.
A Study on the Mechanism Regulating Acetate to Propionate Ratio in Rumen Fermentation by Dietary Carbohydrate Type

The research direction of our team is nutrition and physiology of ruminants, including dietary nutrition metabolism and rumen microorganisms. Previous research has shown that ruminal acetate-to-propionate ratio is related to diet utilization efficiency. At present, it is believed that the main factors affecting the ruminal acetate-to-propionate ratio are the degradation rate of the diet and the rumen microbial structure, but the main mechanism is unclear. This study found that the effect of ruminal acetate-to-propionate ratio was not affected by the concentration of the fermentation substrate, but was affected by the structure of the rumen microbiota. We believe that changes in the rumen microflora structure are the main mechanism for regulating the ruminal acetate-to-propionate ratio. This will help people to further understand the rumen physiology, thereby gradually improving feed conversion efficiency and reducing production costs. Abstract: In order to explore the mechanism by which diet regulates the acetate-to-propionate molar ratio (A: P ratio), we compared the effect on rumen fermentation parameters and the microbiome by altering the ratio of dietary concentrates to roughage ratio and calcium pyruvate infusion. The test animals were Laoshan dairy goats, and were fed continuously through an automatic feeder. The test groups were fed a base diet of low concentrates, and intraruminally infused with calcium pyruvate at two concentrations. The infusion concentrations were derived from the difference in the rate of carbohydrate degradation of the high and low concentrate diets, and they were artificially set such that the high concentration infusion group was infused with twice the concentration as the low concentration infusion group. The control groups were fed high concentrate (6:4) and low concentrate (3:7) diets, respectively. The following results were obtained by measuring rumen fermentation parameters and microbial composition: the rumen A: P ratio was significantly lower in the high-concentrate diet group than in the low concentrate diet group (P 0.05), while infusion of high concentration calcium pyruvate significantly increased the rumen A: P ratio (P effect on rumen microbial structure. The above results indicate that increasing the concentration of the fermentation substrate without affecting the composition of the microflora does not reduce the A: P ratio. Microbiological results showed that the A: P ratio was more closely related to the rumen microflora structure. Therefore, it is believed that rumen microflora structure is the main mechanism regulating A: P ratio in rumen fermentation.
