Large scale massive MIMO field trial for 5G mobile communications system (2016)

Higher spectrum efficiency is a target of the 5th generation (5G) mobile communications system. Massive MIMO is considered as one of important technologies for that purpose. Under the practical conditions that the number of antennas on user equipment (UE) is limited, multi-user MIMO (MU-MIMO) is a probable use scenario of Massive MIMO. Furthermore, massive connectivity is another important target, and MU-MIMO under high UE correlations could occur in the massive connectivity scenarios. By taking these targets and scenarios into account, Huawei and NTT DOCOMO have conducted a large scale field trial to evaluate the feasibility of massive MIMO, especially the performance of linear, non-linear, and hybrid precoding MU-MIMO schemes.
Modem link-property advertisements (2012)

Devices and associated applications are increasingly connected to a variety of smart modems that have dynamically varying link characteristics. For example, incoming and outgoing link rates can be varied over time with adaptive coding and modulation to suit the channel characteristics. In addition, those links may go up and down due to a variety of factors. The link rate and conditions offered by the modem to connected devices and associated applications therefore vary. In order to autonomously condition traffic and allow the network to get the most out of the modem's link capacity, the upstream devices and applications need to be informed of the modem's link conditions. This becomes a form of cognitive networking. This paper will discuss the problem and present a simple protocol that can be used to provide upstream devices and applications with downstream link conditions. While the protocol in this document is described in the context of modem radio-frequency link properties, it can also be broadly applied to other scenarios such as cryptographic devices.
Receiver-based bandwidth sharing for streaming client with multiple connections (2015)

Recently, HTTP has been widely used for video delivery over the Internet. In many cases, a client receives video data via multiple concurrent connections regardless of limited bandwidth resource that may result in low quality of experience. In this work, we present a client-based method for sharing the capacity of a last-hop access link for multiple connections. Our method estimates the overall bandwidth of the access link and simultaneously controls TCP receivers' window sizes to achieve a particular target bitrate for each HTTP connection. Experiment results show that our solution can maintain the throughputs of multiple connections and quickly respond to large bandwidth changes.

Single scan STEM-EMCD in 3-beam orientation using a quadruple aperture (2022)

The need to acquire multiple angle-resolved electron energy loss spectra (EELS) is one of the several critical challenges associated with electron magnetic circular dichroism (EMCD) experiments. If the experiments are performed by scanning a nanometer to atomic-sized electron probe on a specific region of a sample, the precision of the local magnetic information extracted from such data highly depends on the accuracy of the spatial registration between multiple scans. For an EMCD experiment in a 3-beam orientation, this means that the same specimen area must be scanned four times while keeping all the experimental conditions same. This is a non-trivial task as there is a high chance of morphological and chemical modification as well as non-systematic local orientation variations of the crystal between the different scans due to beam damage, contamination and spatial drift. In this work, we employ a custom-made quadruple aperture to acquire the four EELS spectra needed for the EMCD analysis in a single electron beam scan, thus removing the above-mentioned complexities. We demonstrate a quantitative EMCD result for a beam convergence angle corresponding to sub-nm probe size and compare the EMCD results for different detector geometries.
Novel compact double balanced coplanar active mixer Application to a single chip MMIC receiver for satellite repeater (2001)

This paper proposes a new compact double balanced coplanar mixer suitable for satellite repeaters. Compared to the present 14/12GHz satellite mixers, its size is divided by 3 and it provides 2dB gain instead of the classical 10dB loss. This mixer was successfully integrated with 4 other functions in a single chip receiver MMIC.
Data from Phase 1b Clinical Trial with Alpelisib plus Olaparib for Patients with Advanced Triple-Negative Breast Cancer (2023)

&lt;div&gt;AbstractPurpose:&lt;p&gt;We had previously reported on the safety and the recommended phase 2 dose (RP2D) of olaparib in combination with the PI3Kα-specific inhibitor alpelisib in patients with high-grade serous ovarian cancer as studied in a phase 1b trial (NCT01623349). Here, we report on the breast cancer cohort from that study.&lt;/p&gt;Patients and Methods:&lt;p&gt;Eligible patients had recurrent triple-negative breast cancer (TNBC) or recurrent breast cancer of any subtype with a germline &lt;i&gt;BRCA&lt;/i&gt; mutation and were enrolled to a dose-escalation or -expansion cohort. After definition of the RP2D, secondary end points included safety and objective response rate (ORR). Exploratory analyses were performed using circulating-free DNA (cfDNA).&lt;/p&gt;Results:&lt;p&gt;Seventeen patients with TNBC were enrolled with a median of three prior lines of chemotherapy. The most common treatment-related grade 3–4 adverse events were hyperglycemia (18%) and rash (12%). The ORR was 18% (23% for patients treated at the RP2D) and 59% had disease control. The median duration of response was 7.4 months. Analysis of cfDNA tumor fractions (TFx) revealed that patients with TFx &lt; 15% after completion of the first cycle had a longer progression-free survival compared with those with TFx ≥ 15% (6.0 vs. 0.9 months; &lt;i&gt;P&lt;/i&gt; = 0.0001).&lt;/p&gt;Conclusions:&lt;p&gt;Alpelisib in combination with olaparib is tolerable in patients with pre-treated TNBC, with evidence of activity in non-&lt;i&gt;BRCA&lt;/i&gt; carriers. cfDNA provided important prognostic information. Results highlight potential synergistic use of a PI3K inhibitor to sensitize HR-proficient (BRCA wild-type) TNBC to PARP inhibition and suggest the potential to expand the use of PARP inhibition beyond &lt;i&gt;BRCA&lt;/i&gt;-mutant tumors.&lt;/p&gt;&lt;/div&gt;
Additive Fabrication and the Mechanisms of Nucleation and Growth in Chemical Vapor Deposition Processes (2000)

In this Account, we present several representative studies of thin-film growth by chemical vapor deposition, with particular emphasis given to elucidating the mechanistic, energetic, and structural aspects of nucleation and growth. These understandings have allowed us to develop new methods to deposit patterned, as opposed to blanket, thin films. We show how such procedures can be exploited to effect the directed assembly (i.e., the additive fabrication) of a device architecture.

On the scope of relationships ~CASE\ (2002)

The concept of relationship scope is a valuable modelling concept with a variety of applications. A particular relationships' scope expresses a constraint upon the entities which may validly be linked together by an instance of the relationship. The scoping of relationships has application to validation of reference relationships, imposing semantics upon the data not otherwise expressible directly by the data model. It can be applied to enrich the concept of composite entities. It can define the constraints necessary to direct relational table generation from entity and object oriented data models. It is one of a range of techniques contributing to our meta-CASE programme of managing the complexity of CASE tools by capturing as many aspects as possible through generic functionality parameterised for specific instances by values captured declaratively.
Comparison of preferred orientation and stress in silver thin films on different substrates using x-ray diffraction (2007)

Silver thin films were deposited on SiO2 and polyethylene naphthalate (PEN) using e-beam evaporation. X-ray diffraction techniques were used to investigate the influence of substrate morphology on the Ag film’s texture. Different modes of texture were observed in Ag thin films on SiO2 and PEN. Detailed information regarding spatial distribution of specific {hkl} planes was obtained by conducting pole figure analyses. A typical stress measurement technique for thin films, sin2ψ analysis, was performed to study how the surface morphology of the various substrates affected the stress induced during the texture evolution of the thin films. Based on the data from this study, the preferred orientation and stress of Ag thin films on SiO2 and PEN were discussed.
Rapid, Selective, Ambient Growth and Optimization of Copper Benzene-1,3,5-Tricarboxylate (Cu–BTC) Metal–Organic Framework Thin Films on a Conductive Metal Oxide (2018)

Metal–organic frameworks (MOFs) are useful for thin film-based device integration as they show high adsorption capacity for selected gases. However, optimized device integration of MOFs for various platforms requires high-quality, well controlled thin film growth techniques that are flexible, scalable, and manufacturable. For this reason, there is a critical need for the ability to grow MOFs in the form of dense and uniform thin films efficiently on a wide range of substrates. In this work, copper benzene-1,3,5-tricarboxylate (Cu–BTC) MOF thin films are rapidly produced at room temperature by using a conductive aluminum-doped zinc oxide (AZO) as a seed layer to template Cu–BTC growth, with growth only occurring on the AZO layer via a hydroxy double salt intermediate. The formation pathway of the Cu–BTC films was investigated in detail because of the significant importance of improving the Cu–BTC film growth from the perspective of optimized device integration. We demonstrate that the structure of the resultant Cu–BTC film could be fine-tuned via alterations to the solvents used during growth conditions, pH, and the identity of the Cu salt anion. The technique described here is rapid, tunable, selective, and applicable to a variety of substrates.
Searching for Efficient Neural Architectures for On-Device ML on Edge TPUs (2022)

On-device ML accelerators are becoming a standard in modern mobile system-on-chips (SoC). Neural architecture search (NAS) comes to the rescue for efficiently utilizing the high compute throughput offered by these accelerators. However, existing NAS frameworks have several practical limitations in scaling to multiple tasks and different target platforms. In this work, we provide a two-pronged approach to this challenge: (i) a NAS-enabling infrastructure that decouples model cost evaluation, search space design, and the NAS algorithm to rapidly target various on-device ML tasks, and (ii) search spaces crafted from group convolution based inverted bottleneck (IBN) variants that provide flexible quality/performance trade-offs on ML accelerators, complementing the existing full and depthwise convolution based IBNs. Using this approach we target a state-of-the-art mobile platform, Google Tensor SoC, and demonstrate neural architectures <sup xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">1</sup> that improve the quality-performance pareto frontier for various computer vision (classification, detection, segmentation) as well as natural language processing tasks.
KnowMe and ShareMe (2014)

There is much recent work on using the digital footprints left by people on social media to predict personal traits and gain a deeper understanding of individuals. Due to the veracity of social media, imperfections in prediction algorithms, and the sensitive nature of one's personal traits, much research is still needed to better understand the effectiveness of this line of work, including users' preferences of sharing their computationally derived traits. In this paper, we report a two- part study involving 256 participants, which (1) examines the feasibility and effectiveness of automatically deriving three types of personality traits from Twitter, including Big 5 personality, basic human values, and fundamental needs, and (2) investigates users' opinions of using and sharing these traits. Our findings show there is a potential feasibility of automatically deriving one's personality traits from social media with various factors impacting the accuracy of models. The results also indicate over 61.5% users are willing to share their derived traits in the workplace and that a number of factors significantly influence their sharing preferences. Since our findings demonstrate the feasibility of automatically inferring a user's personal traits from social media, we discuss their implications for designing a new generation of privacy-preserving, hyper-personalized systems.
Characterization of Aneuploid Populations with Trisomy 7 and 20 Derived from Diploid (2011)

Chromosomal instability leading to aneuploidy occurs in most sporadic colorectal cancers (CRCs) and is believed to be an early driving force in disease progression. Despite this observation, the cellular advantages conferred by these cytogenetic alterationsare poorly understood. Here, weprovideevidencethatserum-free passage oforiginallydiploid, immortalized human colonic epithelial cells (HCECs) gave rise to the acquisition of trisomy 7 (+7), an aneuploidy detected in more than 40% of colorectal adenomas. These cells remain diploid under long-term growth in 2% serum conditions. Analysis by GTG banding and fluorescent in situ hybridization detected no rare preexisting +7 cell in the original population, suggesting a conversion of diploid cells to an aneuploid state. The acquisition of +7 also precedes loss or truncation of the adenomatosis polyposis coli gene as both diploid and +7 cells express full-length, functional protein. Coculturing of fluorescent-labeled cells demonstrate that +7 HCECs have a growth advantage over diploid cellsinserum-freeconditions.Defectsincellmigrationandaberrantregulationoftheepidermalgrowthfactorreceptor, located on chromosome 7p, are also detected in +7 HCECs. Interestingly, knockdown of TP53 and expression of K-Ras V12 in +7 HCECs resulted in the emergence of trisomy 20, another nonrandom aneuploidy observed in ∼85% of CRC. In summary, we describe isogenic colonic epithelial cells that represent cytogenetic changes occurring frequently in sporadic CRC. The emergence and characterization of trisomy 7 and 20 demonstrate that these HCECs may serve as unique human cell–based models to examine the effects of chromosomal instability in CRC progression.

The Carbenoid Approach to Peptide Synthesis (2000)

A different approach to the synthesis of dipeptides is described based on the formation of the NHCHR1CONH-CHR2CO bond by carbenoid N-H insertion, rather than the formation of the peptide bond itself. Thus decomposition of triethyl diazophosphonoacetate catalysed by rhodium(II) acetate in the presence of N-protected amino acid amides 8 gives the phosphonates 9. Subsequent Wadsworth-Emmons reaction of 9 with aldehydes in the presence of DBU gives dehydro dipeptides 10. The reaction has been extended to a simple two-step procedure, without the isolation of the intermediate phosphonate, for conversion of a range of amino acid amides 11 into dehydro dipeptides 12 and to an N-methylamide 11 h, and for conversion of a dipeptide to tripeptide (13-->14). Direct conversion, by using methyl diazophenylacetate, of amino acid amides to phenylglycine-containing dipeptides 19 proceeds in good chemical yield, but with poor diastereoselectivity.

Compact Thermosyphon Using Refrigerant Flow Control. (Improvement of Heat Transfer Characteristics in the Cooling Unit with Multiple Power Modules Vertically Mounted) (1998)

In a compact closed two-phase loop thermosyphon which consists of a multiradiator and a refrigerant bath with multiple power modules mounted vertically, the heat radiation performance deteriorates as the refrigerant bath becomes thinner. We have found that this is because the return condensate is blocked by the back flow of the bubble in the return path when the heat load decreases and increases sharply. We have also improved the heat radiation performance by providing an adiabatic path between the boiling area and the return path.

This software provides the opportunity for quantitative assessment and possible longitudinal surveillance.
Analysis and development of a novel algorithm for the in-vehicle\n hand-usage of a smartphone (2018)

Smartphone usage while driving is unanimously considered to be a really\ndangerous habit due to strong correlation with road accidents. In this paper,\nthe problem of detecting whether the driver is using the phone during a trip is\naddressed. To do this, high-frequency data from the triaxial inertial\nmeasurement unit (IMU) integrated in almost all modern phone is processed\nwithout relying on external inputs so as to provide a self-contained approach.\nBy resorting to a frequency-domain analysis, it is possible to extract from the\nraw signals the useful information needed to detect when the driver is using\nthe phone, without being affected by the effects that vehicle motion has on the\nsame signals. The selected features are used to train a Support Vector Machine\n(SVM) algorithm. The performance of the proposed approach are analyzed and\ntested on experimental data collected during mixed naturalistic driving\nscenarios, proving the effectiveness of the proposed approach.\n
Effect of chlorination on the TlBr band edges for improved room temperature radiation detectors (2015)

Thallium bromide (TlBr) crystals subjected to hydrochloric acid (HCl) chemical treatments have been shown to advantageously affect device performance and longevity in TlBr‐based room temperature radiation detectors, yet the exact mechanisms of the improvements remain poorly understood. Here, we investigate the influence of several HCl chemical treatments on device‐grade TlBr and describe the changes in the composition and electronic structure of the surface. Composition analysis and depth profiles obtained from secondary ion mass spectrometry (SIMS) identify the extent to which each HCl etch condition affects the detector surface region and forms of a graded TlBr/TlBr Cl surface heterojunction. Using a combination of X‐ray photoemission spectroscopy (XPS) and hybrid density functional calculations, we are able to determine the valence band offsets, band gaps, and conduction band offsets as a function of Cl content over the entire composition range of . This study establishes a strong correlation between device process conditions, surface chemistry, and electronic structure with the goal of further optimizing the long‐term stability and radiation response of TlBr‐based detectors.
