Pure-tone thresholds (250 to 8000 Hz) were measured twice in test (n = 18) and control (n = 10) groups. TM electrodes were placed between first and second threshold measurements in the test group, whereas the control group did not receive electrodes. Pure-tone threshold shifts were compared between groups. The effect of TM electrode contact location on threshold shifts was evaluated in the test group. TM electrodes significantly increased average low-frequency thresholds, 7.5 dB at 250 Hz and 4.2 dB at 500 Hz, and shifts were as large as 25 dB in individual ears. Also, threshold shifts did not appear to vary at any frequency with TM electrode contact location. - 'To solve the given system of linear equations with complex coefficients, we can use the Gaussian elimination method. The given system of equations is: (1) 2x + 5y + 3iz = 8i (2) x - 3y + 2z = 1 (3) -4x + 2y + 5iz = -5 First, we will write the augmented matrix for this system: | 2 5 3i | 8i | | 1 -3 2 | 1 | | -4 2 5i | -5 | Next, we will perform row operations to get the matrix in row-echelon form.

To do this, we can subtract half of the first row from the second row: | 2 5 3i | 8i | | 0 -5.5 -1i | -3i | | -4 2 5i | -5 | Now, we will make the first element of the third row 0. To do this, we can add twice the first row to the third row: | 2 5 3i | 8i | | 0 -5.5 -1i | -3i | | 0 12 11i | 11i | Next, we will make the second element of the third row 0.

We can now solve for the variables using back-substitution. From the third row, we have: 10.8i * z = 6i Dividing both sides by 10.8i, we get: z = 6i / 10.8i = 6/10.8 = 1/1.8 = 5/9 Now, we can substitute z back into the second row to find y: -5.5y - 1i(5/9) = -3i Multiplying both sides by -1, we get: 5.5y + (5i/9) = 3i Subtracting 5i/9 from both sides, we get: 5.5y = 3i - 5i/9 = (22i - 5i) / 9 = 17i/9 Dividing both sides by 5.5, we get: y = (17i/9) / 5.5 = 17i / 49.5 = 17i / (99/2) = 34i / 99 Finally, we can substitute y and z back into the first row to find x: 2x + 5(34i/99) + 3i(5/9) = 8i Multiplying both sides by 99, we get: 198x + 5(34i) + 3i(55) = 792i 198x + 170i + 165i = 792i 198x = 792i - 335i = 457i Dividing both sides by 198, we get: x = 457i / 198 So, the solution to the given system of linear equations is: x = 457i / 198 y = 34i / 99 z = 5/9' - Remodelling of the asthmatic airway includes increased deposition of proteoglycan (PG) molecules. One of the stimuli driving airway remodelling may be excessive mechanical stimulation. We hypothesized that fibroblasts from asthmatic patients would respond to excessive mechanical strain with up-regulation of message for PGs. We obtained fibroblasts from asthmatic patients (AF) and normal volunteers (NF) using endobronchial biopsy. Cells were maintained in culture until the fifth passage and then grown on a flexible collagen-coated membrane. Using the Flexercell device, cells were then subjected to cyclic stretch at 30% amplitude at 1 Hz for 24 h. Control cells were unstrained. Total RNA was extracted from the cell layer and quantitative RT-PCR performed for decorin, lumican and versican mRNA. In unstrained cells, the expression of decorin mRNA was greater in AF than NF. With strain, NF showed increased expression of versican mRNA and AF showed increased expression of versican and decorin mRNA. The relative increase in versican mRNA expression with strain was greater in AF than NF. - source_sentence: 'Represent this question for retrieving relevant documents: What is the total arc length of the Lévy C curve after iterating 8 times if the original line segment had a length of 1 unit?' sentences: - "Pose estimation is indeed a fascinating area in computer vision, but it's not\ \ entirely a walk in the park. Estimating the pose of a human or object involves\ \ a combination of complex mathematical techniques and algorithms. Let's delve\ \ deeper into some key aspects of pose estimation:\n\n1). **3D vs 2D Pose Estimation**:\ \ \n - 3D Pose Estimation aims to determine the 3-dimensional pose of a subject,\ \ providing depth information along with the 2D coordinates. This requires specialized\ \ techniques like stereo cameras or depth sensors to capture the 3D structure\ \ of the scene.\n - In comparison, 2D Pose Estimation focuses on estimating the\ \ 2D pose of a subject within a single image or video frame, providing information\ \ about joint locations in the image plane.\n\n2). **Model-based Pose Estimation**:\ \ \n - This approach leverages predefined models of human (or object) skeletons\ \ with known joint connections. The model is then fitted to the input image or\ \ video data to estimate the pose of the subject. \n - A prominent example of\ \ Model-based Pose Estimation is the popular OpenPose library, which utilizes\ \ a part-based model to estimate human poses.\n\n3). **Model-free Pose Estimation**:\ \ \n - Contrary to model-based methods, model-free approaches do not rely on predefined\ \ models. Instead, they directly learn to estimate the pose from raw image or\ \ video data. \n - One such technique is the Convolutional Pose Machine (CPM)\ \ which uses convolutional neural networks to predict heatmaps for body joints,\ \ which are then refined to obtain the final pose estimation.\n\n4). **Case Study:\ \ Human Pose Estimation in Sports Analysis**: \n - Pose estimation plays a crucial\ \ role in sports analysis, enabling the quantification of player movements and\ \ kinematics. \n - For instance, in soccer, pose estimation techniques can be\ \ employed to track player positions, analyze their running patterns, and evaluate\ \ their performance during matches.\n\n5). **Comparative Analysis with Similar\ \ Concepts**: \n - Object Detection: While both pose estimation and object detection\ \ involve locating and identifying objects in images or videos, pose estimation\ \ specifically focuses on determining the pose or configuration of the object,\ \ while object detection primarily aims to identify and localize the object's\ \ presence.\n - Motion Capture: Pose estimation is closely related to motion capture,\ \ which involves tracking and recording the movements of human subjects. Motion\ \ capture systems typically employ specialized sensors or cameras to capture highly\ \ accurate 3D pose data, whereas pose estimation algorithms typically rely on\ \ computer vision techniques to infer poses from 2D or 3D image or video data.\n\ \n6). **Common Misconceptions and Clarifications**: \n - Pose estimation is not\ \ limited to humans: It can also be used to estimate the pose of objects, animals,\ \ and even vehicles.\n - Pose estimation is distinct from facial expression recognition:\ \ While both involve analyzing images or videos of people, pose estimation focuses\ \ on body posture and joint locations, whereas facial expression recognition aims\ \ to identify and interpret facial expressions." - "The Lévy C curve is a self-replicating fractal that is created by iteratively\ \ replacing a straight line segment with two segments, each of which is 1/sqrt(2)\ \ times the length of the original segment, and joined at a right angle. \n\n\ After each iteration, the total arc length of the curve increases by a factor\ \ of 2/sqrt(2), which is equal to sqrt(2). \n\nIf the original line segment has\ \ a length of 1 unit, then after 8 iterations, the total arc length of the Lévy\ \ C curve will be:\n\nArc length = Original length * (sqrt(2))^n\nArc length =\ \ 1 * (sqrt(2))^8\nArc length = 1 * 2^4\nArc length = 1 * 16\nArc length = 16\ \ units\n\nSo, the total arc length of the Lévy C curve after iterating 8 times\ \ is 16 units." - 'If the dictator keeps X points for themselves, the receiver will get the remaining points, which can be calculated as: Y = 10 - X To find the fractional amount of the total points the receiver received, we can create a fraction with Y as the numerator and the total points (10) as the denominator: Fraction = Y/10 = (10 - X)/10 So, the receiver gets a fractional amount of (10 - X)/10 of the total points.' - source_sentence: 'Represent this question for retrieving relevant documents: Detailed Elaboration on Dimensionality Reduction and Industry Application' sentences: - '**Dimensionality Reduction: A Comprehensive Overview** Dimensionality reduction is a fundamental concept in machine learning and data analysis. It involves transforming high-dimensional data into a lower-dimensional representation while preserving the most important information. Dimensionality reduction techniques have a wide range of applications in various industries, such as: * **Feature engineering:** reducing the number of features in a dataset to improve the efficiency of machine learning algorithms. * **Visualization:** enabling the visualization of high-dimensional data by projecting it onto a lower-dimensional subspace. * **Data compression:** reducing the storage and transmission costs of large datasets. **Specific Industry Applications:** * **Computer vision:** Extracting meaningful features from images and videos for object recognition, image segmentation, and facial recognition. * **Natural language processing:** Reducing the dimensionality of text data for text classification, document summarization, and machine translation. * **Bioinformatics:** Analyzing gene expression data and identifying biomarkers for disease diagnosis and drug discovery. * **Financial modeling:** Identifying patterns and trends in financial data for risk assessment, portfolio optimization, and fraud detection. * **Recommendation systems:** Generating personalized recommendations for products, movies, or music based on user preferences.

The only curative treatment is surgery. As hepatocellular carcinoma is often associated with liver cirrhosis, patients are at risk for postoperative liver failure. In the recent years, platelets are thought to play an important role in liver regeneration.The aim of this study was to discover the relevance of postoperative platelet counts after liver resection for hepatocellular carcinoma. Data of 68 patients who underwent liver resection for hepatocellular carcinoma between July 2007 and July 2012 in a single centre were analysed. Postoperative morbidity and mortality were evaluated in regard to postoperative platelet counts. Comparative analysis between patients with platelet counts ≤100 2x109/ l and >100 x109/ l at d1 was performed in regard to postoperative outcome. Within this cohort, 43 patients (63%) suffered from histologically proven liver cirrhosis. Postoperative mortality was statistically significant associated with postoperative reduced platelet counts. Comparative analysis showed significantly elevated postoperative bilirubin levels and lower prothrombin time in patients with platelet counts ≤ 100 1x109/ l at d1. - "Let G be a group of order 25.

The aim of this study was to investigate the above issue. This study enrolled consecutive psychiatric outpatients with mood and/or anxiety disorders who undertook a first visit to a medical center. Migraine was diagnosed according to the International Classification of Headache Disorders, 2nd edition. Three psychometric scales and the Short-Form 36 were administered. General linear models were used to estimate the difference in scores contributed by either migraine or MDE. Multiple linear regressions were employed to compare the variance of these scores explained by migraine or MDE. Among 214 enrolled participants, 35.0% had migraine. Bipolar II disorder patients (70.0%) had the highest percentage of migraine, followed by major depressive disorder (49.1%) and only anxiety disorder (24.5%). Patients with migraine had worse depression, anxiety, and somatic symptoms and lower SF-36 scores than those without. The estimated differences in the scores of physical functioning, bodily pain, and somatic symptoms contributed by migraine were not lower than those contributed by MDE. The regression model demonstrated the variance explained by migraine was significantly greater than that explained by MDE in physical and pain symptoms. - 'Based on the information provided, we only know the number of patients who died within the first year after the surgery.

Oxylipins play a key role in chronic disease progression. It is possible, but unknown, if oxylipin concentrations change with the consumption of functional foods or differ with subject age. Therefore, in a parallel comparator trial, 20 healthy individuals were recruited into a younger (19-28years) or older (45-64years) age group (n=10/group). Participants ingested one muffin/day containing 30g of milled flaxseed (6g alpha-linolenic acid) for 4weeks. Plasma oxylipins were isolated through solid phase extraction, analyzed with HPLC-MS/MS targeted lipidomics, and quantified with the stable isotope dilution method. At baseline, the older group exhibited 13 oxylipins ≥2-fold the concentration of the younger group. Specifically, pro-inflammatory oxylipins 5-hydroxyeicosatetraenoic acid, 9,10,13-trihydroxyoctadecenoic acid, and 9,12,13-trihydroxyoctadecenoic acid were signi... | | Represent this question for retrieving relevant documents: Find the isometries of the metric $ds^2 = dx^2 + dy^2$ over the rectangle $R=[0,a] \times [0,b]$, subject to the additional condition that any isometry $f$ maps $(0,0)$ to $(x_0, y_0)$. Find $x_0$ and $y_0$ such that the isometry $f$ is given by $f(x,y) = (x_0 + x, y_0 - y)$. | An isometry is a transformation that preserves the distance between points. In this case, we are looking for transformations that preserve the metric $ds^2 = dx^2 + dy^2$. Let's consider the transformation $f(x,y) = (x_0 + x, y_0 - y)$ and find the conditions on $x_0$ and $y_0$ for it to be an isometry.

First, let's compute the differential of the transformation:

$$df = \begin{pmatrix} 1 & 0 \\ 0 & -1 \end{pmatrix} \begin{pmatrix} dx \\ dy \end{pmatrix} = \begin{pmatrix} dx \\ -dy \end{pmatrix}$$

Now, let's compute the metric under this transformation:

$$ds'^2 = (dx')^2 + (dy')^2 = dx^2 + (-dy)^2 = dx^2 + dy^2$$

Since $ds'^2 = ds^2$, the transformation $f(x,y) = (x_0 + x, y_0 - y)$ is an isometry.

Now, let's find the conditions on $x_0$ and $y_0$ such that the isometry maps $(0,0)$ to $(x_0, y_0)$. Applying the transformation to $(0,0)$, we get:

$$f(0,0) = (x_0 + 0, y_0 - 0) = (x_0, y_0)$$

Since the transformation maps $(0,0)$ to $(x_0, y_0)$, there are no additional conditions... | | Represent this question for retrieving relevant documents: Do two di-leucine motifs regulate trafficking and function of mouse ASIC2a? | Acid-sensing ion channels (ASICs) are proton-gated cation channels that mediate acid-induced responses in neurons. ASICs are important for mechanosensation, learning and memory, fear, pain, and neuronal injury. ASIC2a is widely expressed in the nervous system and modulates ASIC channel trafficking and activity in both central and peripheral systems. Here, to better understand mechanisms regulating ASIC2a, we searched for potential protein motifs that regulate ASIC2a trafficking. | * Loss: [MultipleNegativesRankingLoss](https://sbert.net/docs/package_reference/sentence_transformer/losses.html#multiplenegativesrankingloss) with these parameters: ```json { "scale": 20.0, "similarity_fct": "cos_sim" } ``` ### Training Hyperparameters #### Non-Default Hyperparameters - `eval_strategy`: steps - `per_device_train_batch_size`: 32 - `per_device_eval_batch_size`: 32 - `num_train_epochs`: 1 - `batch_sampler`: no_duplicates - `multi_dataset_batch_sampler`: round_robin #### All Hyperparameters
