International patent protection: Time for a fully EU functioning supra-national patent mechanism

Larger industrial companies have become increasingly global in their functions and aspirations. With regard to patents, it is increasingly common for a multinational company to face alleged infringing acts committed by the same competitor in several countries. Securing international patent protection both at the acquisition and the enforcement stage is the corollary to the cross border exploitation of patents. The regulation of transnational trade and the international exploitation of patent rights have brought about international agreements concerning these closely related issues, such as international patent granting power, international harmonization of patent laws and uniform systems of jurisdiction and choice of law rules applicable to patent enforcement as well as other areas. However, there is an increasingly strained relationship between international patent acquisition and enforcement1 which is the dominant focus of this paper. Whilst a network of international agreements facilitates the grant of increasingly similar patent rights in many countries, cross border patent enforcement through the application of the relevant private international rules has been very weak. From a private international law perspective, the legal independence and territorial limitations of patent rights has severe implications for the application of the relevant jurisdictional and choice of law rules. Therefore, cross-border adjudication has indeed been challenged in the patent area. This paper seeks to focus on the problems associated with acquiring and enforcing patent rights at a multijurisdictional level, particularly within the EU

Neighbouring residue effects on the ^(15)N chemical shifts of some aliphatic dipeptides

The ^(15)N chemical shifts of a number of simple aliphatic dipeptides have been determined in a aqueous solution and while the amine nitrogen shift is independent of the nature of the neighbouring residue, the peptide nitrogen shift shows a marked dependence upon the nature of the adjacent amino-acid

Narrow Line Cooling and Momentum-Space Crystals

Narrow line laser cooling is advancing the frontier for experiments ranging from studies of fundamental atomic physics to high precision optical frequency standards. In this paper, we present an extensive description of the systems and techniques necessary to realize 689 nm 1S0 - 3P1 narrow line cooling of atomic 88Sr. Narrow line cooling and trapping dynamics are also studied in detail. By controlling the relative size of the power broadened transition linewidth and the single-photon recoil frequency shift, we show that it is possible to continuously bridge the gap between semiclassical and quantum mechanical cooling. Novel semiclassical cooling process, some of which are intimately linked to gravity, are also explored. Moreover, for laser frequencies tuned above the atomic resonance, we demonstrate momentum-space crystals containing up to 26 well defined lattice points. Gravitationally assisted cooling is also achieved with blue-detuned light. Theoretically, we find the blue detuned dynamics are universal to Doppler limited systems. This paper offers the most comprehensive study of narrow line laser cooling to date.Comment: 14 pages, 19 figure

Narrow Line Cooling: Finite Photon Recoil Dynamics

We present an extensive study of the unique thermal and mechanical dynamics for narrow-line cooling on the 1S0 - 3P1 88Sr transition. For negative detuning, trap dynamics reveal a transition from the semiclassical regime to the photon-recoil-dominated quantum regime, yielding an absolute minima in the equilibrium temperature below the single-photon recoil limit. For positive detuning, the cloud divides into discrete momentum packets whose alignment mimics lattice points on a face-centered-cubic crystal. This novel behavior arises from velocity selection and "positive feedback" acceleration due to a finite number of photon recoils. Cooling is achieved with blue-detuned light around a velocity where gravity balances the radiative force.Comment: 4 pages, 3 figures, Phys. Rev. Lett., in pres

Precision spectroscopy and density-dependent frequency shifts in ultracold Sr

By varying the density of an ultracold $^{88}$Sr sample from $10^9$ cm$^{-3}$ to $> 10^{12}$ cm$^{-3}$, we make the first definitive measurement of the density-related frequency shift and linewidth broadening of the $^1S_0$ - $^3P_1$ optical clock transition in an alkaline earth system. In addition, we report the most accurate measurement to date of the $^{88}$Sr $^1S_0 - ^3P_1$ optical clock transition frequency. Including a detailed analysis of systematic errors, the frequency is ($434 829 121 312 334 \pm 20_{stat} \pm 33_{sys}$) Hz.Comment: 4 pages, 4 figures, 1 table. submitte

National Vascular Registry: 2015 Annual Report.

The National Vascular Registry is commissioned by the Healthcare Quality Improvement Partnership (HQIP) to measure the quality and outcomes of care for patients who undergo major vascular surgery in NHS hospitals in England and Wales. It aims to provide comparative information on the performance of NHS vascular units and thereby support local quality improvement as well as inform patients about major vascular interventions delivered in the NHS. As such, all NHS hospitals in England, Wales, Scotland and Northern Ireland are encouraged to participate in the Registry. The measures used to describe the patterns and outcomes of care are drawn from various national guidelines including: the “Provision of Services for Patients with Vascular Disease” document and the Quality Improvement Frameworks published by the Vascular Society, and the National Institute for Health and Care Excellence (NICE) guidelines on stroke and peripheral arterial disease. This report provides a description of the care provided by NHS vascular units, and contains information on the process and outcomes of care for: (i) patients undergoing abdominal aortic aneurysm (AAA) repair, (ii) patients undergoing carotid endarterectomy, (iii) patients undergoing a revascularisation procedure (angioplasty/stent or bypass) or major amputation for lower-limb peripheral arterial disease (PAD). In addition, the report presents the findings of an organisational audit conducted in August 2015

Measurement of Linear Stark Interference in 199Hg

We present measurements of Stark interference in the 6$^1S_0$ $\rightarrow$ 6$^3P_1$ transition in $^{199}$Hg, a process whereby a static electric field $E$ mixes magnetic dipole and electric quadrupole couplings into an electric dipole transition, leading to $E$-linear energy shifts similar to those produced by a permanent atomic electric dipole moment (EDM). The measured interference amplitude, $a_{SI}$ = $(a_{M1} + a_{E2})$ = (5.8 $\pm$ 1.5)$\times 10^{-9}$ (kV/cm)$^{-1}$, agrees with relativistic, many-body predictions and confirms that earlier central-field estimates are a factor of 10 too large. More importantly, this study validates the capability of the $^{199}$Hg EDM search apparatus to resolve non-trivial, controlled, and sub-nHz Larmor frequency shifts with EDM-like characteristics.Comment: 4 pages, 4 figures, 1 table; revised in response to reviewer comment

National Vascular Registry: 2014 Progress Report.

The National Vascular Registry is commissioned by the Healthcare Quality Improvement Partnership (HQIP) to measure the quality and outcomes of care for patients who undergo major vascular surgery in NHS hospitals in England and Wales. It aims to provide comparative information on the performance of NHS hospitals and thereby support local quality improvement as well as inform patients about the care delivered in the NHS. As such, all NHS hospitals in England, Wales, Scotland and Northern Ireland are encouraged to participate in the Registry. The measures used to describe the patterns and outcomes of care are drawn from various national guidelines including: the “2014 The Provision of Services for Patients with Vascular Disease” and the Quality Improvement Frameworks published by the Vascular Society, and the National Institute for Health and Care Excellence (NICE) guidelines on stroke and peripheral arterial disease. In 2014, the Registry published NHS trust and surgeon-level information for elective infrarenal Abdominal Aortic Aneurysm (AAA) repair and carotid endarterectomy on the Registry website. From 28 October, information on both procedures has been available on the www.vsqip.org.uk website for all UK NHS trusts that currently perform them. For English NHS trusts, the same information was published for individual consultants, as part of NHS England’s “Everyone Counts: Planning for Patients 2013/4” initiative. Consultant-level information was also published for NHS hospitals in Wales, Scotland and Northern Ireland for consenting surgeons. This progress report aims to complement that information by (1) providing an overview of care delivered by the NHS at a national level, and (2) describing various developments within the National Vascular Registry. The Registry will publish its next annual report on major vascular surgery in November 2015
