Measurement of Rotational Property for a Baseball in Flight with Acceleration Sensors (2018)

In order to accurately and easily measure the rotational property of a ball in flight, we attempt to use a baseball with a built-in acceleration sensor unit which consists of one three-axis sensor for Low G and three sensors for High G. Two approaches for obtaining the rotational speed and its axis of the ball from outputs of the sensors are investigated; one is based on rotational acceleration component in the outputs and the other is based on translational one. In flight experiments, we obtain the time series data of acceleration for two kinds of flight trajectory of straight and curve balls. By using these experimental data, we measure the rotational speed and rotation axis with the present two algorithms. As the results, in each algorithm it is shown that the rotational speed is decreasing with time, and also that the rotation axis keeps almost constant during the flight. These results indicate the effectiveness of the present algorithms. In particular, the latter result means the validity of our assumption on rotation axis. The estimated rotational speeds are 15.0 rps and 22.4 rps in average for straight and curve ball, and the difference between the results of the two algorithms shows 0.6 rps and 0.03 rps, respectively. On the other hand, the difference in rotation axis is approximately 19 degrees in the case of straight ball while that is 16 degrees in curve ball.

Three-dimensional analysis of surface plasmon resonance modes on a gold nanorod (2009)

We investigate the surface optical properties of a gold (Au) nanorod by using the finite-element method in a three-dimensional model. Results from the near-field optical images show spatially oscillatory patterns (nodal fields) on the surface, and these are attributable to plasmon-mode wave functions. We interpret these phenomena in terms of the electric field nodes on the surface of the rod, and the results show good agreement with our experimental observation in the optical images.

Reduction of NOx in Lean Exhaust by Selective NOx-Recirculation (SNR-Technique) Part I: System and Decomposition Process (1998)

&lt;div class="htmlview paragraph"&gt;The &lt;b&gt;SNR-technique&lt;/b&gt; is a new &lt;b&gt;NOx aftertreatment&lt;/b&gt; system for lean burn gasoline and diesel applications. The objective of &lt;b&gt;SNR is NOx&lt;/b&gt; removal from lean exhaust gas by &lt;b&gt;NOx&lt;/b&gt; adsorption and subsequent selective external recirculation and decomposition of &lt;b&gt;NOx&lt;/b&gt; in the combustion process. The &lt;b&gt;SNR-project&lt;/b&gt; is composed of two major parts. Firstly the development of &lt;b&gt;NOx adsorbents&lt;/b&gt; which are able to store large quantities of &lt;b&gt;NOx&lt;/b&gt; in lean exhaust gas, and secondly the &lt;b&gt;NOx&lt;/b&gt; decomposition by the combustion process.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;Emphasis of this paper is the investigation of &lt;b&gt;NOx&lt;/b&gt; reduction in the combustion process, including experimental investigation and numerical simulation. The &lt;b&gt;NOx&lt;/b&gt; decomposition process has been proven in diesel and lean-burn gasoline engines. Depending on the type of engine &lt;b&gt;NOx-conversion&lt;/b&gt; rates up to 90 % have been &lt;b&gt;observed&lt;/b&gt;. Regarding the complete &lt;b&gt;SNR-system&lt;/b&gt;, including the efficiency of the adsorbing material and the &lt;b&gt;NOx&lt;/b&gt; decomposition by the combustion, a &lt;b&gt;NOx&lt;/b&gt; removal of more than 50% is achievable. By numerical studies the reaction paths of &lt;b&gt;NOx&lt;/b&gt; decomposition have been identified As a main result of the reaction analysis it is presumed that the thermal NO production is decreased and additionally the NO reduction via non-thermal NO reactions is increased.&lt;/div&gt; &lt;div class="htmlview paragraph"&gt;The &lt;b&gt;SNR&lt;/b&gt; project was carried out by an international consortium &lt;b&gt;comprising&lt;/b&gt; five European countries within the framework of the &lt;b&gt;BRITE EURAM PROGRAMME&lt;/b&gt; and with the financial support of the European &lt;b&gt;Community&lt;/b&gt;.&lt;/div&gt;
PCS/W-CDMA dual-band MMIC power amplifier with a newly proposed linearizing bias circuit (2002)

A personal communications service/wide-band code division multiple access (PCS/W-CDMA) dual-band monolithic microwave integrated circuit (MMIC) power amplifier with a single-chip MMIC and a single-path output matching network is demonstrated by adopting a newly proposed on-chip linearizer. The linearizer is composed of the base-emitter diode of an active bias transistor and a capacitor to provide an RF short at the base node of the active bias transistor. The linearizer enhances the linearity of the power amplifier effectively for both PCS and W-CDMA bands with no additional DC power consumption, and has negligible insertion power loss with almost no increase in die area. It improves the input 1-dB gain compression point by 18.5 (20) dB and phase distortion by 6.1/spl deg/ (12.42/spl deg/) at an output power of 28 (28) dBm for the PCS (W-CDMA) band while keeping the base bias voltage of the power amplifier as designed. A PCS and W-CDMA dual-band InGaP heterojunction bipolar transistor MMIC power amplifier with single input and output and no switch for band selection is embodied by implementing the linearizer and by designing the amplifier to have broad-band characteristics. The dual-band power amplifier exhibits an output power of 30 (28.5) dBm, power-added efficiency of 39.5 % (36 %), and adjacent channel power ratio of -46 (-50) dBc at the output power of 28 (28) dBm under 3.4-V operation voltage for PCS (W-CDMA) applications.
Transfer Learning by Borrowing Examples for Multiclass Object Detection (2011)

Despite the recent trend of increasingly large datasets for object detection, there still exist many classes with few training examples. To overcome this lack of training data for certain classes, we propose a novel way of augmenting the training data for each class by borrowing and transforming examples from other classes. Our model learns which training instances from other classes to borrow and how to transform the borrowed examples so that they become more similar to instances from the target class. Our experimental results demonstrate that our new object detector, with borrowed and transformed examples, improves upon the current state-of-the-art detector on the challenging SUN09 object detection dataset. 1
Thyroid Venous Catheterization in the Early Diagnosis of Familial Medullary Thyroid Carcinoma (1982)

In kindreds with familial medullary thyroid carcinoma (MTC), individuals are often detected whose peripheral plasma calcitonin (CT) levels are undetectable in the basal state but increase minimally following provocative testing. The proper management of such patients has been uncertain, but most investigators have advocated repeat testing and evaluation after an interval of several months. The present study was conducted to evaluate the diagnostic implications of these modest increases in plasma calcitonin. In 25 kindred members at direct risk for familial medullary thyroid carcinoma (MTC), basal peripheral plasma calcitonin (CT) levels were less than 240 pg/ml. Following provocative testing with intravenous calcium or pentagastrin or both, calcitonin values remained below 240 pg/ml in eight subjects (Group A), however, they were mildly elevated (260-580 pg/ml) in 12 subjects (Group B) and moderately elevated (700-940 pg/ml) in five subjects (Group C). Following the transfemoral placement of a catheter into the inferior thyroid vein (ITV), provocative testing was repeated, and ITV and peripheral blood samples were collected simultaneously. Basal ITV plasma CT levels were below 240 pg/ml in all patients in Group A, however, they were mildly elevated (500 pg/ml) in one of the 12 patients in Group B and moderately elevated (800 pg/ml, 1400 pg/ml) in two of the five patients in Group C. Following provocation, ITV plasma CT levels became markedly elevated in one patient in Group A and in all of the patients in Groups B(2520+/-635 pg/ml) and C (6322+/-2598 pg/ml). Thyroidectomy was performed in patients whose ITV plasma CT level was elevated following provocative testing. Medullary thyroid carcinoma of C-cell hyperplasia were evident either on microscopic (1/1 patient in Group A;9/12 patients in Group B; and 2/5 patients in Group C), or gross (3/12 patients in Group B;3/5 patients in Group C) examination of thyroidectomy specimens. In only one of 14 patients was metastatic MTC noted on histologic examination of resected cervical lymph nodes. Postoperative peripheral plasma CT levels were unchanged from basal and less than 240 pg/ml following provocative testing in all but one patient. The present study then provides definitive evidence that patients at direct risk for familial MTC who have even minimally abnormal responses in peripheral plasma CT following provocative testing generally harbor some stage of a C-cell proliferative disorder. Identification of such individuals with early disease is important because thyroidectomy offers an extremely high cure rate.
Protecting Public-Access Sites Against Distributed Denial-of-Service Attacks (2004)

A distributed denial-of-service (DDoS) attack can flood a victim site with malicious traffic, causing service disruption or even complete failure. Public-access sites like amazon or ebay are particularly vulnerable to such attacks, because they have no way of a priori blocking unauthorized traffic. We present Active Internet Traffic Filtering (AITF), a mechanism that protects public-access sites from highly distributed attacks by causing undesired traffic to be blocked as close as possible to its sources. We identify filters as a scarce resource and show that AITF protects a significant amount of the victim's bandwidth, while requiring from each participating router a number of filters that can be accommodated by today's routers. AITF is incrementally deployable, because it offers a substantial benefit even to the first sites that deploy it.
Electrical Treeing Behavior in Polyethylene Filled with Aluminum Oxide Nanoparticles (2017)

Electrical treeing behavior in low density polyethyleneand its nanocomposite filled with 1.0 wt% and 3.0 wt%aluminum oxide nanoparticles was investigated bymeans of a real-time microscope recording system and asynchronized partial discharge measurement. Forpreparing the nanocomposite, uncoated aluminum oxidenanoparticles with 99.5% purity (Nanodur, CAS 1344-28-1) were used. These were of almost spherical shapewith an average diameter of 45 nm. The test objectswere prepared in form of the wire-plane electrodegeometry [1]. The electrical treeing tests were carriedout by applying 50 Hz AC voltage at a ramping speed of22 V/s. The obtained experimental results indicate thatthe addition of the nanoparticles has a positive impacton the resistance to electrical treeing. Both the scale andthe shape of the distribution of the treeing initiationvoltage improved. The magnitude of partial dischargeactivity associated with the treeing in polyethylenenanocomposites was also lower than in the referencematerial.
Wireless Control of Smart Battery Systems (2022)

Smart Battery (SB) is a new concept that combines advanced power electronics, wireless communication, and artificial intelligence to increase the performance and extend the lifetime of the battery. In this paper, the concept of wireless control of SB systems is introduced. The hardware design of the electronic circuit needed to implement the smart battery is presented. Moreover, Bluetooth Low Energy (BLE) with connection-oriented is the most interesting solution to obtain lower power consumption and security of the system. The wireless architecture proposed can establish at least 133 connections per second among central control and smart cells. The wireless communication was validated through an experimental wireless development platform.

Velocity-selective coherent population trapping in conjunction with pol-grad cooling in a folded three-level system under standing wave excitation (1993)

We identify the conditions under which velocity selective coherent population trapping (VSCPT) takes place when a three level Λ system is excited by a pair of Raman resonant standing waves.
Fixed full duplex relaying for wireless broadband communication (2012)

We compare full duplex (FD) and half duplex (HD) relaying in terms of coverage range. We consider a practical FD relay model where both the dynamic ranges of transmitter and receiver and the level of the residual loop interference between transmitted and received signals are taken into account. We numerically evaluate the rate performance of the full duplex multi-hop (FD-MH) scheme and the half duplex decode-and-forward (HD-DF) scheme, where the former requires transmit power allocation under the dynamic range constraint. Results show that there is a tradeoff between these two relaying modes.

Femoral fracture type can be predicted from femoral structure: A finite element study validated by digital volume correlation experiments (2017)

Proximal femoral fractures can be categorized into two main types: Neck and intertrochanteric fractures accounting for 53% and 43% of all proximal femoral fractures, respectively. The possibility to predict the type of fracture a specific patient is predisposed to would allow drug and exercise therapies, hip protector design, and prophylactic surgery to be better targeted for this patient rendering fracture preventing strategies more effective. This study hypothesized that the type of fracture is closely related to the patient-specific femoral structure and predictable by finite element (FE) methods. Fourteen femora were DXA scanned, CT scanned, and mechanically tested to fracture. FE-predicted fracture patterns were compared to experimentally observed fracture patterns. Measurements of strain patterns to explain neck and intertrochanteric fracture patterns were performed using a digital volume correlation (DVC) technique and compared to FE-predicted strains and experimentally observed fracture patterns. Although loaded identically, the femora exhibited different fracture types (six neck and eight intertrochanteric fractures). CT-based FE models matched the experimental observations well (86%) demonstrating that the fracture type can be predicted. DVC-measured and FE-predicted strains showed obvious consistency. Neither DXA-based BMD nor any morphologic characteristics such as neck diameter, femoral neck length, or neck shaft angle were associated with fracture type. In conclusion, patient-specific femoral structure correlates with fracture type and FE analyses were able to predict these fracture types. Also, the demonstration of FE and DVC as metrics of the strains in bones may be of substantial clinical value, informing treatment strategies and device selection and design. © 2017 Orthopaedic Research Society.

Wafer-level packaging and laser bonding as an approach for silicon-into-lab-on-chip integration (2013)

A novel approach for the integration of silicon biosensors into microfluidics is presented. Our approach is based on wafer-level packaging of the silicon die and a laser-bonding process of the resulting mold package into a polymer-multilayer stack. The introduction of a flexible and 40 μm thin hot melt foil as an intermediate layer enables laser bonding between materials with different melting temperatures, where standard laser welding processes cannot be employed. All process steps are suitable for mass production, e.g. the approach does not involve any dispensing steps for glue or underfiller. The integration approach was demonstrated and evaluated regarding process technology by wafer-level redistribution of daisy chain silicon dies representing a generic biosensor. Electrical connection was successfully established and laser-bonding tensile strength of 5.7 N mm−2 and burst pressure of 587 kPa at a temperature of 100 °C were achieved for the new material combination. The feasibility of the complete packaging approach was shown by the fabrication of a microfluidic flow cell with embedded mold package.
Tubulin Resists Degradation by Cereblon-Recruiting PROTACs (2020)

Dysregulation of microtubules and tubulin homeostasis has been linked to developmental disorders, neurodegenerative diseases, and cancer. In general, both microtubule-stabilizing and destabilizing agents have been powerful tools for studies of microtubule cytoskeleton and as clinical agents in oncology. However, many cancers develop resistance to these agents, limiting their utility. We sought to address this by developing a different kind of agent: tubulin-targeted small molecule degraders. Degraders (also known as proteolysis-targeting chimeras (PROTACs)) are compounds that recruit endogenous E3 ligases to a target of interest, resulting in the target's degradation. We developed and examined several series of α- and β-tubulin degraders, based on microtubule-destabilizing agents. Our results indicate, that although previously reported covalent tubulin binders led to tubulin degradation, in our hands, cereblon-recruiting PROTACs were not efficient. In summary, while we consider tubulin degraders to be valuable tools for studying the biology of tubulin homeostasis, it remains to be seen whether the PROTAC strategy can be applied to this target of high clinical relevance.

Mode engineering for hybrid SOI/III-V optical devices (2012)

Optical amplifiers are demonstrated by direct bonding III-V gain layers to SOI waveguides which include 2-D and 3-D adiabatic tapers. The 3-D tapers have a low loss of 0.1 dB per mode conversion, the lowest demonstrated for coupling between SOI waveguides of this type. The 2-D tapers are used to control interaction with the III-V gain region. An integrated amplifier delivered 14 dB intra chip gain using the new adiabatic tapered waveguides.
