The effect of baseline serum luteinizing hormone levels on follicular development, ovulation, conception and pregnancy outcome in infertile patients with polycystic ovarian syndrome
Authors: Shanmugham Deepa , Vidhyalakshmi R. K. , M. Shivamurthy H.
Published: December 2017

Background: Polycystic Ovarian Syndrome (PCOS) is the most common endocrine disorder in infertile women. Raised tonic levels of luteinizing hormone (LH) is one of the main endocrinological disturbances in PCOS patients. Objective of present study was to evaluate the effect of baseline serum luteinizing hormone levels on follicular development, ovulation and conception and pregnancy outcome in infertile patients with PCOS.Methods: This is a prospective study conducted on 50 consecutive infertile patients with PCOS. Baseline Day 2 serum luteinizing hormone concentration was done in selected patients. Ovulation induction was done with clomiphene citrate 100 mg from Day 3 to Day 7 of the cycle. Then patients were monitored for follicular development, ovulation, conception and early pregnancy loss.Results: The mean age of the patients is 25±3.6 yrs. The average duration of infertility is 5.4 yrs (2-10). The mean basal serum LH concentration in patients who ovulated was significantly low (5.6 IU) in comparison with patients who did not ovulate (10.1 IU).  The mean basal serum LH concentration in patients who conceived was 3.9 IU in comparison with patients who did not conceive (5.9 IU) which was statistically significant (p=0.04).  Out of 15 patients who conceived, 3 patients (20%) had early pregnancy loss.Conclusions: Tonic hyper secretion of LH results in premature oocyte maturation, causing the problems with fertilization and miscarriage. Inappropriately raised LH appears to have deleterious effects on the pregnancy outcome.
Mid-trimester rupture uterus: case series
Authors: Kapur Aishwarya , Prasad Sudha , Gupta Sangeeta
Published: December 2017

Uterine rupture is an obstetric catastrophe with significant maternal and fetal morbidity and mortality which occurs mainly in the third trimester of pregnancy or during labour, especially in previously scarred uterus. The occurrence of rupture in first and second trimester in women with unscarred uteri is quite rare. We report two cases of rupture uteri managed in our centre at 24 and 26 weeks gestation in women with unscarred uteri. First case was G3P1L1A1, 24 weeks with epigastric pain, stable vitals, epigastric tenderness, USG inconclusive, CT scan showed out pouching of amniotic sac through fundus. Laparotomy done, there was 8-9 cm fundal rupture extending between cornua, uterine repair done. Second case was G3P1L1A1 26 weeks with abdominal pain, stable vitals, corresponding fundal height, head engaged, USG revealed outpouching amniotic sac at the fundus. Laparotomy performed, there was 10 cm rent extending trans-fundal, uterine repair done. Unscarred uterine rupture, especially in early pregnancy is a rare event, posing significant difficulty in diagnosis. Uterine rupture should be first ruled out in all pregnant women presenting with acute abdomen irrespective of gestational age. Search for non-gynaecological causes can delay crucial obstetric intervention that can lead to loss of obstetric function, morbidity and mortality.

Published: December 2017

Soybean, an important legume crop, serves as a good source of protein and oil with tremendous ability to fix atmospheric nitrogen for soil improvement. To study the genetic variability, genotypic, phenotypic and environmental coefficient of variation, broad sense heritability and genetic advance in soybean, a field experiment was conducted during Kharif 2013. The experiment, laid out in a randomized block design (RBD) with three replications, comprised of 24 genotypes and observations on 9 traits of soybean were recorded. In this experiment, analysis of variance indicated that significant variation were present among the different genotypes of the soybean for all the traits under study. The highest genotypic (GCV) and phonotypic coefficient of variation (PCV) were exhibited by the test weight, number of pods per plant, harvest index and plant height. The PCV was found higher than GCV which indicates the important role of environment in the expression of the characters. High heritability and high genetic advance were observed in the test weight, number of pods per plant, harvest index and plant height. The combination of the high heritability and high genetic advance provide the clear image of the trait in the selection process for crop improvement programme.
Estimating bearing capacity of shallow foundations by artificial neural networks
Authors: Aytekin Mustafa
Published: December 2017

In this study, the Artificial Neural Network, ANN is applied to data extracted from a large set of random data created by using Terzaghi and Meyerhof formulae. By using MS Excel, 3750 sets of data for Terzaghi's equation, 4000 for Meyerhof's equation were generated. A simulated ANN was trained on a subset of bearing capacity data, and the performance was tested on the remaining data. The performances of the ANN models were compared to Terzaghi and Meyerhof results. ANN models were as accurate as the other techniques in estimating the ultimate bearing capacity. The models estimated the ultimate bearing capacity with an average error of around 1% of the value obtained from Terzaghi and Meyerhof equations, and the coefficient of determination (r2) was almost equal to 1. Their sensitivity and specificity is dependent on the function and the algorithm used in the training process. Validation subset is crucial in preventing the over-fitting of the ANN models to the training data. ANN models are potentially useful technique for estimating the bearing capacity of the soil. Large training data sets are needed to improve the performance of data-derived algorithms, in particular ANN models.
Mechanical and thermal behaviors comparison of basalt and glass fibers reinforced concrete with two different fiber length distributions
Authors: Yıldızel Sadık Alper
Published: December 2017

This paper deals with the mechanical and thermal behavior of glass and basalt fiber reinforced concrete. Two different composites were studied containing either basalt or glass fibers. Fiber ratios were selected as 1%, 1.25% and 1.5% for glass fiber; 0.3%, 0.4% and 0.5% for basalt fibers. Fiber length was preferred as 12 mm and 24 mm. The addition of basalt fiber had very limited effect on the compressive, flexure and thermal conductivity properties compared to the glass fiber reinforced composite. The results also showed that composites having fibers with the length of 12 mm had better mechanical properties. Heat transfer simulation of the composites were also conducted. It was obtained that both fibers with the length of 12 mm had very close results on the heat transfer studies.
Strain Localization during Equal-Channel Angular Pressing analyzed by Finite Element Simulations
Authors: Horn Tobias Daniel , Silbermann Christian Bert , Frint Philipp , Wagner Martin Franz-Xaver , Ihlemann Jörn
Published: December 2017

Equal-Channel Angular Pressing (ECAP) is a method used to introduce severe plastic deformation into a metallic billet without changing its geometry. In special cases strain localization occurs and a pattern consisting of regions with high and low deformation (so-called shear and matrix bands) can emerge. This paper studies this phenomenon numerically adopting two-dimensional finite element simulations of one ECAP pass. The mechanical behavior of aluminum is modeled using phenomenological plasticity theory with isotropic or kinematic hardening. The effects of the two different strain hardening types are investigated numerically by systematic parameter studies: While isotropic hardening only causes minor fluctuations in the plastic strain fields, a material with high initial hardening rate and sufficient strain hardening capacity can exhibit pronounced localized deformation after ECAP. The corresponding finite element simulation results show a regular pattern of shear and matrix bands. This result is confirmed experimentally by ECAP-processing of AA6060 material in a severely cold worked condition, where microstructural analysis also reveals the formation of shear and matrix bands. Excellent agreement is found between the experimental and numerical results in terms of shear and matrix band width and length scale. The simulations provide additional insights regarding the evolution of the strain and stress states in shear and matrix bands.

Published: December 2017

Philippines as an archipelago and tropical country, which is situated near the Pacific ocean, faces uncertain rainfall intensities. This makes environmental, agricultural and economic systems affected by precipitation difficult to manage. Time series analysis of Philippine rainfall pattern has been previously done, but there is no study investigating its probability distribution. Modeling the Philippine rainfall using probability distributions is essential, especially in managing risks and designing insurance products. Here, daily and cumulative rainfall data (January 1961 - August 2016) from 28 PAGASA weather stations are fitted to probability distributions. Moreover, the fitted distributions are examined for invariance under subsets of the rainfall data set. We observe that the Gamma distribution is a suitable fit for the daily up to the ten-day cumulative rainfall data. Our results can be used in agriculture, especially in forecasting claims in weather index-based insurance.
Visualizing the Provenance of Personal Data using Comics
Authors: Schreiber Andreas , Struminski Regina
Published: December 2017

Personal health data is acquired, processed, stored, and accessed using a variety of different devices, applications, and services. These are often complex and highly connected. Therefore, use or misuse of the data is hard to detect for people, if they are not capable to understand the trace (i.e., the provenance) of that data. We present a visualization technique for personal health data provenance using comics strips. Each strip of the comic represents a certain activity, such as entering data using a smartphone application, storing or retrieving data on a cloud service, or generating a diagram from the data. The comic strips are generated automatically using recorded provenance graphs. The easy-to-understand comics enable all people to notice crucial points regarding their data such as, for example, privacy violations.

Published: December 2017

The article has evaluation of four years observation of the prospective varieties of winter rye Yantarnaya in comparison with the standard in the nursery of the competitive variety trial of the Ural Scientific Research Institute for Agriculture in Yekaterinburg and the results of a two year test in the system of FGBU «Gossortkomissiya». A winter rye is widely used for bread baking mainly. This culture has resistance from negative environmental factors. The main cause of limited use of a winter rye grain for forage is high content water-soluble pentosans over 1.5%. They reduce availability of nutrients to an organism. Creation of varieties with low content of water-soluble pentosans is the rational solution of increase in use of parts of grain of a winter rye in forage production. Together with VIR, a variety with the required characteristics was transferred to the state grade testing. The observation took place in 2013–2017, with contrasts on the weather conditions. According to FGBU «Gossorgkomissiya», the variety has high potential productivity and significantly exceeds same low pentosan variety in the yield.

Experience of Emergency Department Patients With Using the Talking Pole Device: Prospective Interventional Descriptive Study (Preprint)
Authors: Yoo Junsang , Soh Ji Yeong , Lee Wan Hyoung , Chang Dong Kyung , Lee Se Uk , Cha Won Chul
Published: December 2017

BACKGROUND

Patient engagement is important. However, it can be difficult in emergency departments (EDs).

OBJECTIVE

The aim of this study was to evaluate the satisfaction of ED patients using a patient-friendly health information technology (HIT) device, the “Talking Pole,” and to assess the factors relevant to their satisfaction.

METHODS

This study was conducted in May 2017 at the ED of a tertiary hospital. The “Talking Pole” is a smartphone-based device attached to a intravenous infusion pole with sensors. It is capable of sensing patient movement and fluid dynamics. In addition, it provides clinical information from electronic medical records to patients and serves as a wireless communication tool between patients and nurses. Patients and caregivers who entered the observation room of the ED were selected for the study. The “Talking Pole” devices were provided to all participants, regardless of their need for an intravenous pole upon admittance to the ED. After 2 hours, each participant was given an 18-item questionnaire created for this research, measured on a 5-point Likert scale, regarding their satisfaction with “Talking Pole.”

RESULTS

Among 52 participants recruited, 54% (28/52) were patients and the remaining were caregivers. In total, 38% (20/52) were male participants; the average age was 54.6 (SD 12.9) years, and 63% (33/52) of the participants were oncology patients and their caregivers. The overall satisfaction rate was 4.17 (SD 0.79 ) points. Spearman correlation coefficient showed a strong association of “overall satisfaction” with “comparison to the previous visit” (ρ=.73 ), “perceived benefit” (ρ=.73), “information satisfaction” (ρ=.70), and “efficiency” (ρ=.70).

CONCLUSIONS

In this study, we introduced a patient-friendly HIT device, the “Talking Pole.” Its architecture focused on enhancing information delivery, which is regarded as a bottleneck toward achieving patient engagement in EDs. Patient and caregiver satisfaction with the “Talking Pole” was positive in the ED environment. In particular, correlation coefficient results improved our understanding about patients’ satisfaction, HIT devices, and services used in the ED.
FORCED CONVECTION DRYING OF INDIAN GROUNDNUT: AN EXPERIMENTAL STUDY
Authors: Sahdev Ravinder Kumar , Kumar Mahesh , Dhingra Ashwani Kumar
Published: December 2017

In this paper, convective and evaporative heat transfer coefficients of the Indian groundnut were computed under indoor forced convection drying (IFCD) mode. The groundnuts were dried as a single thin layer with the help of a laboratory dryer till the optimum safe moisture storage level of 8 – 10%. The experimental data were used to determine the values of experimental constants C and n in the Nusselt number expression by a simple linear regression analysis and consequently, the convective heat transfer coefficient (CHTC) was determined. The values of CHTC were used to calculate the evaporative heat transfer coefficient (EHTC). The average values of CHTC and EHTC were found to be 2.48 W/m2 oC and 35.08 W/m2 oC, respectively. The experimental error in terms of percent uncertainty was also estimated. The experimental error in terms of percent uncertainty was found to be 42.55%. The error bars for convective and evaporative heat transfer coefficients are also shown for the groundnut drying under IFCD condition.
CRANIOFACIAL STRESS PATTERNS AND DISPLACEMENTS AFTER ACTIVATION OF HYRAX DEVICE: FINITE ELEMENT MODELLING
Authors: Bosiakov Sergei , Vinokurova Anastasiya , Dosta Andrei
Published: December 2017

Rapid maxillary expansion is employed for the treatment of cross-bite and deficiency of transversal dimension of the maxilla in patients with and without cleft of palate and lip. For this procedure, generally, different orthodontic appliances and devices generating significant transversal forces are used. The aim of this study is the finite-element analysis of stresses and displacements of the skull without palate cleft and the skull with unilateral and bilateral cleft after activation of the Hyrax orthodontic device. Two different constructions of the orthodontic device Hyrax with different positions of the screw relative palate are considered. In the first case, the screw is in the occlusal horizontal plane, and in the other, the screw is located near the palate. Activation of the orthodontic device corresponds to the rotation of the screw on one-quarter turn. It is established that the screw position significantly affects the distributions of stresses in skull and displacements of the cranium without palate cleft and with unilateral or bilateral palate cleft. Stresses in the bone structures of the craniums without cleft and with cleft are transferred from the maxilla to the pterygoid plate and pharyngeal tubercle if the screw displaces from the occlusal plane to the palate. Depending on the construction of the orthodontic appliance, the maxilla halves in the transversal plane are unfolded or the whole skull is entirely rotated in the sagittal plane. The stresses patterns and displacements of the skull with bilateral palate cleft are almost unchanged after activation of the orthodontic devices with different positions of the screw, only magnitudes of stresses and displacements are changed. The obtained results can be used for design of orthodontic appliances with the Hyrax screw, as well as for planning of osteotomies during the surgical assistance of the rapid maxillary expansion.
COMPUTERIZED RADIAL ARTERY PULSE SIGNAL CLASSIFICATION FOR LUNG CANCER DETECTION
Authors: Zhang Zhichao , Umek Anton , Kos Anton
Published: December 2017

Pulse diagnosis, the main diagnosis method in traditional Chinese medicine, is a non-invasive and convenient way to check the health status. Doctors usually use three fingers to feel three positions; Cun, Guan, and Chi of the wrist pulse, to diagnose the body’s healthy status. However, it takes many years to master the pulse diagnosis. This paper aims at finding the best position for acquiring wrist-pulse-signal for lung cancer diagnosis. In our paper, the wrist-pulse-signals of Cun, Guan, and Chi are acquired by three optic fiber pressure sensors of the same type. Twelve features are extracted from the signals of these three positions, respectively. Eight classifiers are applied to detect the effectiveness of the signal acquired from each position by classifying the pulse signals of healthy individuals and lung cancer patients. The results achieved by the proposed features show that the signal acquired at Cun is more effective for lung cancer diagnosis than the signals acquired at Guan and Chi.

Authors: Boshevski Bojan , Mircheski Ile
Published: December 2017

This paper presents the development process of a bicycle helmet through individual research, creation, presentation and analysis of the results of the most important product development stages. The quality of the development and manufacturing process of the protective equipment for extreme sports is an imperative for a successful product and its flawless function. The design of the bicycle helmet is made following the rules of the design in order to create a well-founded and functional product. After creating design sketches, a virtual prototype was developed in "SolidWorks" using the required ergonomic dimensions. 3D printed model of the human head with adapted ergonomic dimensions and the designed bicycle helmet was developed in order to verify the applied ergonomic measures. The virtual model will be used as an input in the finite element analysis of the helmet impact test based on the EN1078 standard and the aerodynamic simulations executed in "SolidWorks Simulation and Flow Simulation", for verification of the impact and aerodynamic properties. Virtual testing of aerodynamic features and the ability of the bicycle helmet to allow ventilation of the user's head indicate that the helmet performs its function in the desired way. Also, the virtual prototype will be used for the production process simulation in "SolidWorks Plastics" in order to analyze the production of the bicycle helmet. The polycarbonate helmet outer shell is subject to a number of simulations for the sake of analyzing the production process in order to obtain the desired characteristics of the polycarbonate outer shell and to avoid the disadvantages that occur in the manufacturing process. The main goal of this paper is to develop a safety bicycle helmet with improved ergonomic, validation of impact, aerodynamic characteristics and production process in order to produce a high quality product for mass use.

To facilitate understanding of this concept, the cable winding/unwinding process on only one winch is analyzed. The obtained variables which characterize the kinematics of the cable smooth winding/unwinding process are nonlinear and smooth. This result is important because the systems for the smooth cable winding/unwinding process on the winch could be parts of any cable driven mechanism. These systems can be used in various fields of human activity. For the verification of the presented theoretical contributions, a novel software package named SMOWIND – OW has been developed using MATLAB.

Наглядное представление пространственных характеристик объектов является отдельным направлением визуализации. Использование трех- и четырехмерного изображения позволяет наглядно показывать количественные и реляционные характеристики пространственно ориентированных данных и быстро идентифицировать в них тренды. В статье показаны особенности визуализации данных в интегрированной системе безопасности потенциально опасных, критически важных объектов (ПОО и КВО) и территорий, представляющей собой сложный программно-технический комплекс, позволяющий оперативно оценивать поступающую информацию, оперативно обрабатывать ее, принимать необходимые меры по предупреждению и реагированию при возникновении угроз чрезвычайных ситуаций природного, техногенного и террористического характера. При описании подсистемы визуализации системы производственного мониторинга ПОО подчеркивается, что особенностью отображения данных о физической защищенности объектов в представляемой геоинформационной системе безопасности является бесшовный виртуальный, четырехмерный мир с возможностью интеграции, управления и анализа пространственно-временных данных от различных систем. В основу архитектуры ГИС-безопасности объектов положена доменная (кластерная) структура. Каждый кластер более низкого иерархического уровня связан с одним из доменов более высокого уровня, при этом реализуется интегральная оценка безопасности кластера предыдущего иерархического уровня. Информация о контролируемых объектах поступает на соответствующие уровни принятия решений, автоматизированно распределяется в соответствии с полномочиями и обязанностями пользователей и сложившейся иерархией управления. Подробно изложены существующие функции подсистемы отображения, порядок формирования отчетов, визуализации состояния системы мониторинга на удаленных серверах и отображение качества связи с объектом контроля в виде специальных пиктограмм, функции карточек происшествий и др. Описание работы подсистемы отображения, интегрирующей пространственно-временные данные, снабжено рисунками и таблицами, наглядно иллюстрирующими различные ее функции. В целях своевременного устранения возникших неисправностей элементов систем безопасности авторами предложена автоматизированная система контроля обслуживания технических средств охраны систем физической защиты объектов.

В данной статье рассматривается один из способов тестирования цифровых микросхем, а именно, тестирование с помощью стендового оборудования Formula 2k. Тестирование позволяет повысить качество выпускаемой продукции благодаря отбраковке некачественных элементов, в чем заинтересован конечный потребитель. Тестирование микросхем предполагает решение таких задач, как подготовка конструкторской документации, разработка программного обеспечения для тестирования оборудования и его отладки. Исходным материалом для этого является техническая документация на проверяемую микросхему. Из документации выбираются важнейшие параметры, позволяющие судить о качестве микросхемы при ее тестировании. На основе этих выбранных параметров создается печатная плата для их измерения. В ходе подготовки к тестированию используется программное обеспечение для создания переходной платы. Для нее конструкторская документация разрабатывается на базе пакета программ AltiumDesigner. Для подключения микросхемы к переходной плате используется специальное контактирующее устройство. Оно также создается в среде AltiumDesignerисходя из схем его устройства. Это контактирующее устройство связывает выводы микросхемы с контактными площадками на переходной плате. На основе технических условий и Datasheet для тестируемой микросхемы определяются допуски на значения параметров, которые необходимы для измерения. Исходя из этих данных производится разработка программного обеспечения на специализированном языке тестера Sinopи, выполняется настройка тестера для проведения измерений. После выполнения отладки и всех измерений формируются выходные данные измеряемых параметров. Если все измеряемые параметры соответствуют заявленным, микросхема проходит контроль, в ином случае она отбраковывается.

В рамках теории структурно-энерговременных полей (теория СЭВ-полей) свойств физических объектов при описании резания металлических материалов предлагается использовать пространственную физико-геометрическую интерпретацию предмета исследования, рассмотренную на примере анализа процесса цилиндрического фрезерования. При одном из вариантов технологического процесса, используя параметры фрезерования t, υ, t э (t - глубина резания, м; υ - скорость главного движения резания, м·мин-1 ; t э - опытное время за одно перемещение заготовки, мин), имеем возможность операцию резания за одно перемещение заготовки представить в пространственных декартовых прямоугольных координатах в виде структурно-энерговременного поля П1 (СЭВ-поле), геометрический образ которого отображен в виде прямоугольного параллелепипеда. Объему параллелепипеда ставится в соответствии физическая величина П1 , являющаяся обобщенной характеристикой предмета исследования (процесса фрезерования). Уравнение СЭВ-поля процесса срезания стружки за одно перемещение заготовки относительно вращающейся фрезы в октанте t - υ - t э : П1 = С·Э·В = t·υ· t э . Единица измерения величины П1 : [П1 ] = [С·Э·В] = [ t ]·[ υ ]·[t э ] = 1 мД3 × 1 м·мин-1Д3 × 1 минД3 = 1 м2 (мин/мин)Д9, где (мин/мин) - оболочка О единицы величины; Д9 - оператор движения. Понятия оболочки О и оператора движения Д введены в теории СЭВ-полей для более глубокого анализа предмета исследования. Выражение 1 м 2 (мин/мин) Д9 - пример обозначения единицы измерения СЭВ-поля П1 , как одного из вариантов технологии процесса фрезерования. Здесь оболочка (мин/мин) показывает, что П1 является функцией времени. Описанная методика дает возможность выразить каждый конкретный вариант режима фрезерования одним числовым показателем. Схема физико-геометрической интерпретации предмета исследования для данной задачи позволяет обозначить каждый режим фрезерования определенной физической величиной, поскольку по осям координатного угла могут откладываться разные параметры. Она повышает геометрическую наглядность результатов, получаемых аналитическими средствами, способствуя более глубокому теоретическому осмыслению технологического процесса, а также осознанному формированию знаний и компактности их представлений.

Introduction: Detection of cardiovascular risk in young age is important to motivate them to modify life styles and seek health care early to lower the chances of acquiring cardiovascular disease in later age. This study was done to assess cardiovascular risk factors among first year medical students.

Methods: A cross-sectional study was conducted throughout September and October 2017 in which all first year medical students from a medical college were assessed for the presence of cardiovascular risk factors. Participants’ demography, family history of illness, anthropometric measurements, and blood reports of lipid profile and fasting glucose were acquired. Data were analyzed with Statistical Package for Social Sciences (SPSS-21).

Result: There were 99 participants; 55 males and 44 females. One or more risk factors were present in 87 (87.9%) participants. Moreover, 67.7% (n = 67) participants had more than one risk factors. Low HDL-cholesterol was the most common (n = 55, 55.6%) risk factor followed by elevated triacylglycerol (n = 47, 47.5%) and family history of hypertension (n = 45, 45.5%). There was no significant difference in presence of various risk factors between genders.

Conclusion: There was higher prevalence of cardiovascular risk factors among first year medical students. Majority of them had more than one risk factors. Low HDL-cholesterol was the most common risk factor. The risk factors were comparable in males and females.
Active hip orthosis for assisting the training of the gait in hemiplegics
Authors: Popovic Dejan , Veg Aleksandar
Published: December 2017

The gait restoration is a significant component of the rehabilitation of patients with hemiplegia after central nervous system lesion. The typical symptom of the disability is the lack of hip extension during the stance phase and hip flexion during the swing phase of the affected leg; therefore, asymmetry and perturbed balance while walking. We developed a new modular orthosis for assisting hip flexion and extension during the therapeutic sessions of the gait in hemiplegic individuals based on thorough analysis of the gait characteristics of normal gait. The system is designed to fit into the powered postural controller Walkaround?. The system is developed based on the estimation of torque and power requirement for the gait at speeds up to 1.1 m/s. The model used for the simulation is a known double pendulum in the sagittal plane. The kinematics and dynamics used as the input for the simulation have been recorded in the gait laboratory with eight cameras and force platforms. The system needs to be clinically evaluated before it possibly can be turned into innovation.
