Non-metric calibration of camera lens distortion (2002)

This paper addresses the problem of calibrating camera lens distortion, which can be significant in medium to wide angle lenses. Our approach is based on the analysis of distorted images of straight lines. We derive a new distortion measure that can be optimized using nonlinear search techniques to find the best distortion parameters that straighten these lines. Unlike the other existing approaches, we also show how to use this measure to find fast, closed-form solutions to the distortion coefficients. Some experiments to evaluate the performance of this approach on synthetic and real data are reported.
FATIGUE STRENGTH OF SUPER HIGH STRENGTH BOLT (2005)

The super high strength bolt which has about 1400N/mm^2 tensile strengthof is developed. In this super high strength bolt, the shape of the bolt thread bottom and the shape of imperfect tfread are improved so that this super-high strength bolt may improve the performance to delayed fracture. Though the cause of the delayed fracture and the fatigue fracture is different, the parts improved to the delayed fracture is expected to bring good results for fatigue strength. In this paper, the fatigue strength of super high strength bolts is described. The shape of bolt thread bottom, the bolt strength, and the kind of the bolt material are taken as test parameters. And from the test results, the results of considering the influence that these test parameters give to fatigue strength are described.
Automatic equalizer for digital magnetic recording systems (1987)

This paper describes a new adaptive automatic equalizer based on both Linear Cancellation and probablistic decoding techniques for eliminating Intersymbol Interference in digital magnetic recording systems. It is confirmed that sufficient eye opening and error rate improvements can be achieved using this equalizer at an operation speed of 46 Mbps.
PHOTOCONDUCTIVITY IN SINGLE-CRYSTAL Pb1−xSnx Te (1968)

Photoconductivity at wavelengths up to 15 μ at 77°K and up to 20 μ at 4.2°K has been observed in Bridgman-grown and subsequently annealed crystals of Pb1−xSnx Te which had carrier concentrations ranging from 2 to 8 × 1015 cm−3 with a mobility of about 3 × 104 cm2/V-sec at 77°K. Detectivity values generally were between 108 and 109 cm/W-sec1/2 at 77°K and greater than 1010 cm/W-sec1/2 at 4.2°K. Photoconductive lifetimes of about 10−8 at 77°K and higher temperatures and 10−6 sec at 4.2°K were measured by means of light pulses from a GaAs diode laser.
Molecular Complex of Cholecystokinin-8 and N-Terminus of the Cholecystokinin A Receptor by NMR Spectroscopy (1999)

The bimolecular complex of the C-terminal octapeptide of cholecystokinin, CCK-8, with the N-terminus of the CCK(A)-receptor, CCK(A)-R(1-47), has been structurally characterized by high-resolution NMR and computational refinement. The conformation of CCK(A)-R(1-47), within the lipid environment used for the spectroscopic studies, consists of a well-defined alpha-helix (residues 3-9) followed by a beta-sheet stabilized by a disulfide linkage between C18 and C29, leading to the first transmembrane alpha-helix (TM1). Titration of CCK(A)-R(1-47) with CCK-8 specifically affects the NMR signals of W39 of the receptor, in a saturable fashion. This association is specific for CCK-8; no association was observed upon titration of CCK(A)-R(1-47) with other peptide hormones. The ligand/receptor complex was characterized by intermolecular NOEs between Tyr(27) and Met(28) of CCK-8 and W39 of CCK(A)-R(1-47). These findings suggest that CCK-8 binds to CCK(A) with the C-terminus within the seven-helical bundle and the N-terminus of the ligand, projecting out between TM1 and TM7, forming specific interactions with the N-terminus of the CCK(A) receptor. This mode of ligand binding, consistent with published mutagenesis studies, requires variation of the interpretation of recent findings from photoaffinity cross-linking studies.
Bayesian design of decentralized hypothesis testing under communication constraints (2014)

We consider a distributed detection system under communication constraints, where several peripheral nodes observe a common phenomenon and send their observations to a fusion center via error-free but rate-constrained channels. Using the minimum expected error probability as a design criterion, we propose a cyclic procedure for the design of the peripheral nodes using the person-by-person methodology. It is shown that a fine-grained binning idea together with a method for updating the conditional probabilities of the joint index space at the fusion center, decrease the complexity of the algorithm and make it tractable. Also, unlike previous methods which use dissimilarity measures (e.g., the Bhattacharyya distance), a-prior hypothesis probabilities are allowed to contribute to the design in the proposed method. The performance of the proposed method is compared to a method due to Longo et al.'s and it is shown that the new method can significantly outperform the previous one at a comparable complexity.
Joint detection and classification convolutional neural network on weakly labelled bird audio detection (2017)

Bird audio detection (BAD) aims to detect whether there is a bird call in an audio recording or not. One difficulty of this task is that the bird sound datasets are weakly labelled, that is only the presence or absence of a bird in a recording is known, without knowing when the birds call. We propose to apply joint detection and classification (JDC) model on the weakly labelled data (WLD) to detect and classify an audio clip at the same time. First, we apply VGG like convolutional neural network (CNN) on mel spectrogram as baseline. Then we propose a JDC-CNN model with VGG as a classifier and CNN as a detector. We report the denoising method including optimally-modified log-spectral amplitude (OM-LSA), median filter and spectral spectrogram will worse the classification accuracy on the contrary to previous work. JDC-CNN can predict the time stamps of the events from weakly labelled data, so is able to do sound event detection from WLD. We obtained area under curve (AUC) of 95.70% on the development data and 81.36% on the unseen evaluation data, which is nearly comparable to the baseline CNN model.
The oxytocin receptor signalling system and breast cancer: a critical review (2020)

Breast cancer is making up one-quarter of all new female cancer cases diagnosed worldwide. Breast cancer surgeries, radiation therapies, cytotoxic chemotherapies and targeted therapies have made significant progress and play a dominant role in breast cancer patient management. However, many challenges remain, including resistance to systemic therapies, tumour recurrence and metastasis. The cyclic neuropeptide oxytocin (OT) elicits a plethora of biological responses via the oxytocin receptor (OTR) in both the central and peripheral nervous system, including social bonding, stress, maternal behaviour, sexual activity, uterus contraction, milk ejection and cancer. As a typical member of the G protein-coupled receptor family, OTR represents also an intriguing target for cancer therapy. There is emerging evidence that OTR plays a role in breast cancer development and progression, and several breast cancer cell lines express OTR. However, despite supporting evidence that OT lowers breast cancer risks, its mechanistic role in breast cancer development and the related signalling pathways are not fully understood. Here, we review the current knowledge of the OT/OTR signalling system in healthy breast tissue as well as in breast cancer, and discuss OTR as a potential therapeutic target for breast cancer management.
High Availability for VM Placement and a Stochastic Model for Multiple Knapsack (2017)

k-HA (high-Availability) is an important faulttolerance property of VM placement in clouds and clusters - it is the ability to tolerate up to k host failures by relocating VMs from failed hosts without disrupting other VMs. It has long been assumed [1] that deciding the existence of a k-HA placement is ΣP 3 -hard. In a surprising yet simple result we show that k-HA reduces to multiple knapsack and hence is in NP= ΣP 1 . We propose a stochastic model for multiple knapsack that not only captures real-world workloads but also provides a uniform basis for comparing the efficiencies of different polynomial-time heuristics. We prove, using the central limit theorem and linear programming, that, there exists a best polynomial-time heuristic, albeit impractical from the standpoint of implementation. We turn to industry practice and discuss the drawbacks of commonly used heuristics-First- fit,Best-fit,Worst-fit,MTHM and CSP. Load-balancing is a fundamental customer requirement in industry. Based on a large real-world dataset of cluster workloads (from industry leader Nutanix) we show that the natural load-balancing heuristic - Water- filling - has several excellent properties. We compare and contrast Water-filling with MTHM using our stochastic model and find that Water-filling is a heuristic of choice.
A framework for assessing value chain agility (2006)

Purpose To gain understanding of value chain (VC) agility in terms of value‐adding processes, this paper seeks to present a VC agility framework and then to develop the involved constructs. Design/methodology/approach A framework of VC agility and its theoretical underpinnings is presented. Within the framework, drivers and determinants of VC agility are identified as characteristics enabling flexibility within key components of a firm's VC. Also, it is posited that information technology (IT) capability impacts the levels of achieved flexibility and agility, and that VC agility impacts business performance. Findings From scale development, key determinants of flexibility within VC activities are identified. Correlation analysis suggests that firms derive higher levels of agility through integrating information across the VC rather than within VC activities. Firms with flexibility in their VC functions enjoy higher levels of ensuing VC agility and on‐time delivery, ROA, and market share. Research limitations/implications While the sample size is adequate for scale development, it is not adequate for structural equation modeling since the guideline is to have at least five survey responses for every item measure. Thus, insights were gleaned from initial analysis based on correlations. Practical implications Managerial insights concerning key value‐adding activities that build flexibility and ultimately agility are identified. Originality/value To the best of one's knowledge, this work is the first to operationalize VC agility from the perspective that agility is derived from flexibility in the VC processes and is enabled by IT integration. From exploratory research, insights are gained on how VC agility links with business performance.
Band structure properties of novel BxGa1−xP alloys for silicon integration (2011)

We have grown and investigated the band-structure properties of novel III-V alloys based upon BxGa1−xP. These layers are utilized as strain-compensating layers for the lattice-matched integration of novel direct bandgap Ga(NAsP) quantum well lasers on silicon. Experimental and theoretical studies reveal the dependence of the direct and indirect band gaps for strained BxGa1−xP layers grown on silicon as a function of Boron composition from which we derive the properties of free-standing BxGa1−xP. For Boron fractions up to 6%, we find that the bowing parameter for the lowest (indirect) band gap is − 6.2 ± 0.2 eV. High crystalline quality and promising optical material properties are demonstrated and applied to monolithically integrated Ga(NAsP)/(BGa)P multi-quantum well heterostructures on (001) silicon substrates. Our results show that novel (BGa)P layers are suitable for strain compensation purposes, which pave the way towards a commercial solution for the monolithic integration of long term stable laser diodes on silicon substrates.
Clinical results after anterior mini-open approach for femoroacetabular impingement in early degenerative stage (2010)

We describe our modified anterior mini-invasive technique and results obtained in our first consecutive 117 cases in 105 patients. To assess the influence of preoperative Tönnis degenerative stage, cases were divided into group A (Tönnis 0, 32 hips), B (Tönnis 1, 61 hips), and C (Tönnis 2, 24 hips). The clinical score Dexeus combined score (DCS) was used preoperatively, 3 months, 6 months, and every year after operation. At 3-month follow-up, impingement test results improved significantly in 30 hips of group A (94%; p&lt;0.001) and in 58 of group B (95%; p&lt;0.001), whereas in group C, improvement was observed in only 14 cases (58%; p&gt;0.05). No statistical difference was observed at 3-year visit in all groups. Merle d'Aubigné-Postel and WOMAC scores improved significantly in group A (p&lt;0.001) and B (p&lt;0.001) after 1 year and remained unchanged at subsequent yearly follow-ups. For group C, clinical outcomes scores did not show any significant improvement overall (p&gt;0.05). We concluded that anterior mini-invasive technique is an effective method to treat femoroacetabular impingement, and results are highly influenced by preoperative degenerative state, especially in stage Tönnis 2. Therefore, it seems to be a reasonable early surgical treatment in symptomatic patients.
[A Case of Successful Stomach-Preserving Pancreaticoduodenectomy with Celiac Artery Resection after Neoadjuvant Chemoradiation Therapy for Pancreatic Cancer with Hepatic Arterial Variation]. (2016)

Here we report a case of successful stomach-preserving pancreaticoduodenectomy with celiac artery resection for pancreatic cancer with hepatic arterial variation. A 70-year-old woman was referred to our hospital for examination and treatment of pancreatic cancer. A CT scan showed a tumor with suspected portal vein invasion at the body and head of the pancreas, in contact with the common hepatic artery and the splenic artery with 360°involvement. Contact with the celiac artery and left gastric artery was less than1 80°. CT and angiography revealed hepatic arterial variation in which the right hepatic artery and the left hepatic artery arose from the superior mesenteric artery and the left gastric artery, respectively. Resectability status was considered as borderline resectable. After neoadjuvant chemoradiation therapy, the levels of the serum tumor markers declined remarkably and a CT scan showed SD(RECIST). Subtotal stomach-preserving pancreaticoduodenectomy with celiac artery resection(SSPPD-CAR)was performed without resectionof the left gastric artery and a pathological R0 resectionwas achieved. The significance of performing combination resection and reconstruction of a major artery in pancreatic cancer is unclear. However, there may be cases with vascular variants that enable radical resection without reconstruction of the common hepatic artery. Therefore, it is important to preoperatively evaluate the configuration of the artery accurately and to select the optimal surgical procedures onthe basis of these variations.
Anesthesia for craniotomy: a double-blind comparison of alfentanil, fentanyl, and sufentanil. (1990)

Using a prospective, randomized, and double-blind study design, alfentanil (n = 15), fentanyl (n = 14), or sufentanil (n = 16), in combination with N2O, were administered to patients undergoing craniotomy for supratentorial tumor resection. Physicians were given two syringes, one of which was labeled as "load" for the initial loading dose and the other as "maintenance" for continuous infusion. The concentration of drug in each syringe was adjusted to permit administration on a milliliter per kilogram basis. The target loading doses for alfentanil, fentanyl, and sufentanil were 75, 10, and 1 microgram/kg, respectively, and initial infusion rates were 33.5, 2.0, and 0.3 microgram.kg-1.h-1, respectively. Additional supplementary boluses and changes in maintenance infusion rate were made according to predetermined guidelines. Isoflurane, in increasing 0.2% inspired increments, was used only when the maximum allowed opioid dose had been given (i.e., supplementary bolus doses equal to 75% of the calculated loading dose or supplementary bolus doses equal to 50% of the calculated loading dose combined with a 50% increase in the maintenance infusion rate). Opioid infusions were stopped at the time of bone flap replacement. Antihypertensive medications and naloxone were subsequently given at the discretion of the anesthesiologist. Group demographics were not different. Total volumes of drug were similar among groups indicating equipotent preparations. Administration of isoflurane, antihypertensive medications, and naloxone were not different among groups. Although decreases in blood pressure seen with induction were similar among groups, alfentanil-treated patients received ephedrine more frequently before intubation. Thirty minutes after entry into the postanesthesia recovery area, respiratory rate and pH were lowest in sufentanil-treated patients.(ABSTRACT TRUNCATED AT 250 WORDS)
OPTICAL AND ULTRAVIOLET STELLAR FLARE SPECTROSCOPY (1983)

As for solar flares, one of the most physically revealing types of data for M-dwarf flares are high-resolution, time-resolved spectra. Due to the intrinsically faint nature of the M-dwarf stars, spectroscopic data has tended to be of low spectral (˜ 5 Ǻ) and temporal (˜ 5 min) resolution. However, with the development of image intensified spectrographs and fast, efficient digital detectors, the last several years have seen the successful acquisition of both high time and spectral resolution M-dwarf flare spectra. Recent programs have also been successfully conducted using the International Ultraviolet Explorer (IUE) satellite to obtain UV and EUV spectra of M-dwarf flares. These data reveal that dwarf M star flares are remarkably similar to solar flares in all aspects of their spectroscopic phenomenology.
An Evaluation of use of Accelerated Loading Equipment for Determination of Fatigue Performance of Asphalt Pavement in Laboratory (2004)

In this study, a model hot mix asphalt (HMA) pavement was constructed in the laboratory and tested under repeated wheel load applications using Model Mobile Load Simulator 3 (MMLS3). This study presents a discussion on the background of MMLS3, production of test slabs, use of various strain gauges, loading, data acquisition using strain gauges in various directions and analysis of test results. Analysis of data showed the effect of wheel load on fatigue performance of the pavement in terms of strain history and cracking. Different phases of strain history have been identified and their role on fatigue performance discussed. A rational approach of calculation of strain corresponding to failure load applications has also been presented. A finite element model of MMLS3 pavement showed the usefulness of numerical solutions over closed form solutions with respect to effects of boundary conditions. The finite element model presented in this paper successfully described the behavior of the pavement loaded with the MMLS3 in terms of effect of variation of pavement thickness and relative magnitude of strains in different directions. Based on the observations from several trials involving preparation of test pavement slabs and, loading and testing, it is concluded that the MMLS3 can be used for evaluation of HMA for fatigue characterization. A proper protocol for preparation of slabs, loading and testing with the MMLS3 is being developed. Once developed, the protocol will be used for more rigorous HMA material characterization in the laboratory.
Panoramic 3D Reconstruction Using Rotational Stereo Camera with Simple Epipolar Constraints (2006)

In this paper, we propose a novel method for panoramic 3D scene recovery using rotational stereo cameras with simple epipolar constraints. By rotating two parallel stereo cameras about a vertical axis with a constant velocity, we acquire two sampled spacio-temporal volumes which are made of the sequential images captured by a uniform angular interval. The two spacio-temporal volumes can be resampled into a set of multi-perspective panoramas. We analyze the epipolar geometry among images (panoramas and original images) of two spacio-temporal volumes. The result shows that only three types of simple epipolar constraints (epipolar line is row or column of image) exist in the two spacio-temporal volumes. Then we compute a depth map from four image pairs using a multi-baseline algorithm with the three types of epipolar constraints; that is horizontal, vertical and combination of them. Experimental results using both synthetic and real images show that our approach produces high quality panoramic 3D reconstruction.
Ovarian reserve in reproductive age women with type 1 diabetes (2018)

Background: Premature aging are frequently observed among individuals with type 1 diabetes. Decrease of ovarian reserve may be one of the characteristics of such process.&#x0D; Aims: To evaluate the ovarian reserve function in female patients of reproductive age with type 1 diabetes in comparison with healthy women.&#x0D; Materials and methods: This study evaluated 224 Caucasian women, age 1837 years with type 1 diabetes and 230 healthy women of comparable age. Serum concentrations of anti-Mullerian hormone (AMH), inhibin B, follicle stimulating hormone (FSH), luteinizing hormone (LH), estradiol, progesterone and testosterone were compared on the 23 day of menstrual cycle as ovarian volume and antral follicle count (AFC). In addition, glycated hemoglobin level (HbA1c%) was evaluated.&#x0D; Results: We reveal statistically significant difference in following parameters in diabetic women in comparison with healthy women: AMH, AFC. But even in diabetic patients parameters remained within reference ranges. There was a pronounced negative relationship between the levels of HbA1c% and AMG.&#x0D; Conclusions: Ovarian reserve function parameters decrease in young women with type 1 diabetes in comparison with healthy women, but ovarian reserve parameters are in normal reference range. These findings are important in pregnancy planning consulting by gynecologists and endocrinologists. We must recommend to women with type 1 diabetes more early planning of natural pregnancy for treatment with reproductive technology in cases of prolog absence of nature pregnancy.
TGF-β production by eosinophils drives the expansion of peripherally induced neuropilin− RORγt+ regulatory T-cells during bacterial and allergen challenge (2022)

Eosinophils are best known for their effector functions in settings of parasitic infection or allergen challenge, but have also increasingly been implicated in immune regulation at mucosal sites. Here, we show using bacterial infection and antigen challenge models that extrathymic Foxp3+ regulatory T-cells that arise de novo in the context of bacterial infection require an intact eosinophil compartment. Mouse strains with a constitutive or conditional eosinophil deficiency, or with an eosinophil-specific ablation of Tgfb, lack bacterially induced neuropilin-negative, RORγt-positive gastrointestinal Treg populations in models of Helicobacter pylori, Helicobacter hepaticus and Citrobacter rodentium infection, as well as in the steady state colon and upon oral ovalbumin challenge. Treg priming in lymph nodes appears not to be impaired. Eosinophil-dependent tissue-resident Tregs express CTLA4, ICOS, CD39 and T-bet in addition to RORγt. Eosinophils reside in close proximity to Tregs in infected tissues, and specifically induce the expansion of newly formed Tregs, but not conventional T-cells in vivo and in vitro. TGF-β expression in eosinophils is induced by bacterial contact and during allergen exposure. Specific Tgfb ablation in eosinophils and the associated Treg defects result in excessive T-cell responses in the examined Th2- but not Th1-polarized settings.
